Description:
SMOKING DEVICE FIELD OF THE INVENTION The present invention relates to smoking devices. More particularly, the present invention relates to personal and portable hookah-based smoking device having a changeable and disposable tobacco cartridge and a method of using the same.

BACKGROUND OF THE INVENTION The traditional hookah or the water-pipe is a well known smoking device that was originally invented in Turkey and was used especially in oriental and middle-east countries. Since then, the hookah has become very popular in other cultures and penetrated into western countries for the last few decades.

Thé hookah is related also to the traditional oriental custom of smoking in groups of several people in cafés or restaurants while using a single hookah having an inhaling pipe that is transferred from one individual to the others.

Smoking hookah is a social custom that involves also the preparation of the tobacco mixture and the burning material as well as introducing the mixture and the burning material in a special part of the hookah.

The traditional hookahs as well as modern water-pipes generally comprise a bottle-like part that is adapted to receive water and a connectable tube having a portion that is adapted to receive the tobacco. The connectable tube is provided with a pipe having two openings wherein one of the openings is. adapted to receive the smoke from the tobacco and the other end reaches the water in the bottle-like part so that smoke coming from the tobacco bubbles out through the water to the bottle and the connectable tube. The connectable tube is further provided with another flexible pipe through which

smoke is inhaled. The smoke passes through the water before it is inhaled by the smokers through a mouthpiece.

The passage of the tobacco smoke through water before inhaling the smoke into the mouth and lungs of the user has two objectives: First, some of the materials in the smoke are absorbed in the water without loosing the taste and aroma of the smoke. Therefore, the amount of harmful materials that reach the mouth and lungs of the user is reduced markedly. In fact, the water acts as a filter. Secondly, the water gives the smoke coolness that no cigarette, cigar or another pipe can provide.

One of the disadvantages of smoking a hookah in groups of people is that everyone has to smoke the same tobacco that has a certain taste and aroma. There are many types of tobacco as well as many types of fruit molasses and other flavor materials that smokers wish to mix in their tobacco.

Each one of the mixtures has a certain taste and aroma. People develop preferences towards a certain tobacco mix and do not want to smoke a tobacco that is chosen by other smokers. This brought about the minimization of the hookah and presentation of a small hookah for which the user prepare his own favorite tobacco.

Another disadvantage of using a hookah in groups of people is that transferring the hookah from mouth to mouth is non-hygienic. There are many people that do not want to smoke from a water pipe that was used by other people. Again, the minimized hookah can partially solve the problem.

For smoking the traditional hookah as well as the minimized one, the smoker has to prepare his own mixture of tobacco and other tastes and flavors as well as the burning material while making some preparation in order to enable smoking. Not all people have the time or the delight to prepare the smoking mixtures and would have wanted to smoke tobacco and enjoy the advantages of smoking a hookah without having to make any preparations.

Moreover, there is a need to provide a portable smoking device that is hookah-based and can be smoked at work and relatively rapidly without having to go through the tedious preparation of the mixtures and the burning materials.

DETAILED DESCRIPTION OF THE INVENTION AND THE FIGURES The present invention provides a new and unique smoking device that is based on the traditional hookah; however, the smoking device of the present invention is portable. The Hookah-based smoking device is also personal in the sense that it is not designed to be transferred between a few smokers and an individual smoker can smoke it alone.

An additional unique feature of the hookah-based smoking device is in the possibility to provide the tobacco in a specially designed cartridge that is connected to the smoking device. The cartridge can contain tobacco having different tastes and aromas. This feature eliminates the need of the smoker to mix and prepare the tobacco mixture and the burning material on his own. The tobacco mixture and the burning material are provided in a disposable cartridge that is changeable. Cartridges of various tobacco types are available so that the smoker can change the cartridge according to his needs and taste.

In a preferred embodiment of the present invention, the hookah-based smoking device comprises a tube through which the user inhales the smoke.

The smoke is originated from a connectable tobacco cartridge in which the burning products and preferably tobacco burns using a burning material such as coal. The coal has to be of such a kind that burns quickly. The tobacco cartridge is open to the air so as to facilitate an effective burning of. the tobacco and the burning material. The tobacco cartridge can preferably be screwed onto the tube. The cartridge is disposable. The hookah-based smoking device further comprises a container that is connected to the tube.

The container is adapted to receive a fluid such as water. The smoke generated in the tobacco cartridge enters the tube through a pipe having an opening that is positioned in the water in the container. The smoke that passes through the pipe bubbles out from the opening that is positioned in the water. The user, which inhales the smoke, receives smoke that is cooled by the water and is partially lack in some of the ingredients that are not desirable and are being absorbed by the water while passing through them. It should be

emphasized that the cartridge can be filled with materials other than tobacco.

It can be filled with herbs of any kind such as healing or medicine herbs.

Reference is now made to Figures 1a, b, and c illustrating a frontal view, a side view and an upper view of a hookah-based smoking device in accordance with a preferred embodiment of the present invention. Smoking device 10 comprises a tube 12 having a mouthpiece preferably provided with a stem 14 and a bit 15 through which smoke that is received in tube 12 can be inhaled by a user. Tube 12 is provided with two openings; a first opening 16, which is concentric to the tube, and a second opening 18, which is preferably provided on the side of the tube. First opening 16 is provided with a screw 20 to which a complementary screw of a tobacco cartridge 22 can be connected.

Tobacco cartridge 22 is concentric with respect to tube 12 and is provided with a side port 24. Side port 24 is provided with a seal 26 having a clasp 28 with which seal 26 can be removed of tobacco cartridge 22 (the seal is clearly shown in Figure 1c). Seal 26 is preferably a flexible sheet that is adhered on the edges of side port 24. A comprehensive explanation regarding tobacco cartridge 22 and other optional embodiments of tobacco cartridges are disclosed herein after.

Second opening 18 of tube 12 is provided with a screw 30 to which a complementary screw of a container 32 can be connected. Smoke generated in tobacco cartridge 22 is transferred into tube 12 through container 32.

Container 32 is preferably filled with water (not shown in Figure 1) so that the smoke bubbles through the water before entering tube 12. While the smoke bubbles pass through the water, some of the materials that are generated by the burning process of the tobacco are absorbed by the water that acts as a filter. Moreover, the smoke in the bubbles is cooled by the water and the user inhales cooled smoke.

It is noted that the container may be filled with any fluid that may act as an absorbent or a solution that comprises an absorbent material as well as a mixture within an absorbent material is mixed. However, water is generally a common and efficient absorbent that can be found anywhere.

In order to better understand the passage of the smoke generated in the tobacco cartridge into the tube through the container, reference is now made to Figure 2 illustrating a cross sectional frontal view of the tube of the hookah- based smoking device shown in Figure 1. First opening 16 is provided with a plug 40 having a bore 42. A substantially L-shaped pipe 44, having a first opening 47 and a second opening 48, pass through tube 12. First opening 47 is placed in bore 42 of plug 40 so that smoke generated in tobacco cartridge (not shown in Figure 2) is communicating with pipe 44 and there is no direct aerodynamic connection between the tobacco cartridge and tube 12. A portion of pipe 44 that comes out of second opening 18 is positioned outside tube 12. The portion of pipe 44 that is outside tube 12 is adapted to be positioned in container 32 that is screwed onto screw 30 (the container is not shown in Figure 2). Second opening 48 is positioned in container 32 inside the water that is received in the container.

When the user inhales through the mouthpiece of smoking device 10, the pressure in the cavity of tube 12 is reduced as well as the pressure in container 32. Therefore, smoke is driven to pass through pipe 44 from tobacco cartridge 22 and into container 32. The smoke bubbles through the water in the container in order to equilibrate the pressure in the container and in the tube. Container 32 is fluidically connected to tube 12 so that the smoke that bubbles out from pipe 44 is free to fill the cavity in tube 12 and to be inhaled by the user through bit 15.

Since the container is filled with water and there is a possibility that the water will enter tube 12 if smoking device 10 is held in a declined manner, opening 18 is provided with a plug 50. Plug 50 is provided with a first hole 52 through which pipe 44 passes and preferably two additional bores provided with valves 54. In a preferred embodiment that is shown in Figure 2, valves 54 are operated such as a snorkel. The valves are clearly shown in Figure 2c, which is an enlargement of the valves in the bores. The walls of the bores as well as the valves are conical so that the upper openings of the valves that face tube 12 are smaller than the bottom openings that face container 32.

Each one of valves 54 is provided with a light ball 56 that is caged in the valve

using preferably four hooks 60. When the water is in the container and the user inhales through the mouthpiece, the smoke is free to pass through valves 54. If the smoking device is inclined and the water reaches opening 18, light balls 56, which are light enough to float on the water surface, are upwardly advancing towards the upper openings of valves 54. Since the diameter of the balls 56 is slightly longer than the diameter of the upper openings of the valve, balls 56 seal the openings so that water cannot enter tube 12.

In order for the hookah-based smoking device 10 to be stable in a position where the device is not decline, container 32 is shaped so that it is provided with a broad base. The device can be mounted on a surface while it is supported by the broad base and water cannot enter the tube.

Reference is now made to Figure 3 illustrating a frontal view of a hookah- based smoking device in accordance with another preferred embodiment of the present invention. Hookah-based smoking device 100 generally comprises similar parts as smoking device 10, however, smoking device 100 is provided with a tube-like container 102 that is screwed onto screw 30. Tube-like container is provided with a flat base 104 that supports smoking device 100 when it is mounted on a surface. In this way, the possibility of water entering the tube is lessened.

Reference is now made to Figure 4 illustrating a cross sectional view of the two optional containers in accordance with preferred embodiments of the present invention, disassembled from the hookah-based smoking device.

Generally, the container that is adapted to receive water can be of any shape.

As mentioned herein, container 32 as well as container 102 are provided with a broad base adapted to support the smoking device when placed on a surface. When the containers are disassembled from the smoking device, they can be supported also by the broad base. A cover 106 is provided as an accessory to the hookah-based smoking device assembly so that when the smoking device is not in use, the container is kept closed. Cover 106 is provided with a screw 108 that corresponds the screw that is provided on the container.

As mentioned herein before, one of the objects of the water is to filter the smoke. Some of the materials in the smoke bubbles that pass through the water are absorbed in the water. The amount of absorbed materials depends on the time the bubbles travels in the water, a factor that depends on the height of the water above opening 48 of pipe 44 (the pipe is not shown in Figure 4). For example, the time in which the bubbles travel in water 110 in container 102 is longer than the time the bubbles travel in the water 112 in container 32. The user can choose the containers shape and size according to his needs and desires as well as the height of the water. The same is applied on the coolness of the smoke that will be inhaled by the user. The more time the bubbles are in the water, the cooler the smoke will be.

The tobacco cartridge can be an empty cartridge that is filled by the user with tobacco and burning material or a cartridge that can be supplied as a disposable cartridge that can be changed in every use.

Reference is now made to Figures 5a-e illustrating different views as well as cross sectional views of the tobacco cartridge of the hookah-based smoking device shown in Figure 1. Figures 5 a, b illustrate an upper and frontal views of tobacco cartridge 22 provided with seal 26. Seal 26 is removed from port 24 when the user wishes to use the smoking device while port 24 has two purposes. The first is to light the burning material and the tobacco that is placed within tobacco cartridge 22 and the second purpose is to allow air with oxygen to be in contact with the burning material so as to enable the heating of the tobacco. Tobacco cartridge 22 has a connection 150 that is provided with a screw 157 that is screwed onto a tube such as tube 12 (not shown in Figure 5). Tobacco cartridge 22 is provided with a seal 154 that seals the cartridge when the smoking device is not in use in order to preserve the tobacco's freshness inside the cartridge. Seal 154 can be replaced by a cover that is screwed onto screw 157. When the cartridge is provided with a single port for lighting, the preferred method of lighting the coal is to hold the cartridge upside down while it is lighted and turning it back afterwards.

Figures 5c and d are frontal and side cross sectional views of tobacco cartridge 22, respectively. Tobacco cartridge 22 is provided with tobacco 156 that resides at the bottom part of the cartridge. Tobacco 156 can be of any kind or can be a mixture of tobacco and other materials that enriches the taste and the aroma of the tobacco. Tobacco 156 is confined in the cartridge so it will not spread out upon removal of seal 154 by a mesh screen 170 that is provided adjacent a hole 168 on the bottom part of the cartridge. Hole 168 allows communication of smoke between the cartridge where the tobacco resided and pipe 44 that is adjacent to connection 150 that connects the cartridge and the tube. A mesh screen 172 adjacent to the bottom of cartridge 22 is adapted to prevent the tobacco from spreading out. Burning material 158 that is preferably coal is placed on top of tobacco 156 so that when burning material 158 is lighten and burns, tobacco 156 is heated. As can be seen from Figure 5d, burning material is preferably designed as a stick so as to facilitate clean and uniform combustion.

A perforated sheet 160 is placed between tobacco 156 and burning material 158. Figure 5e is an upper cross sectional view of tobacco cartridge 22. Perforated sheet 160 is clearly shown in the figure. Perforated sheet 160 is adapted to separate tobacco 156 and burning material 158 so that they will not mix and the taste of the tobacco will be purer. The perforations facilitate the smoke from the burning material to pass through the tobacco as well as oxygen from the air to be in good contact with the tobacco.

It is optional to provide a tobacco cartridge having separate openings; a first opening for lighting the burning material and a second opening allowing air to be in contact with the burning material.

Reference is now made to Figures 6 a-f illustrating different views and cross sectional views of a tobacco cartridge in accordance with another preferred embodiment of the present invention. In tobacco cartridge 200 side port 24 is adapted only for allowing air to be in contact with the coal and the tobacco so as to facilitate efficient combustion. In order to light the coal, an additional opening 202 is provided opposite connection 150. A coal stick 204

is accommodated within the upper part of tobacco cartridge 200. Coal stick 204 can be withdrawn from the cartridge through additional opening 202 so as to facilitate its lighting (clearly shown in Figure 6f which is a side view of the cartridge). Coal stick 204 is provided with a stopper 206 that prevents the complete ejection of the coal stick from tobacco cartridge 200. Additional opening 202 is provided with a screwed cover 208 that keeps the cartridge closed at all times except the time the coal is lighted.

It is emphasized again that the tobacco cartridge in the hookah-based smoking device can be designed as a disposable cartridge so that plurality of cartridges in which different types of burning products are provided, is supplied. Each cartridge can be provided with the tobacco or tobacco mixture of certain taste and aroma. The user can change the cartridge when the tobacco is fully burnt or when he desires for another taste. The tobacco cartridge is disposable so that when the tobacco is fully burnt, the user disposes of the cartridge and connects another one to the tube of the smoking device. The other option is to supply an empty tobacco cartridge in which the user fills in the tobacco as well as the burning material. The tobacco cartridges are preferably made of a material that is adapted to allow combustion of the burning products that are engages within. It is preferably made from a ceramic material, however any other material is covered by the scope of the present invention.

Reference is now made to Figure 7, illustrating the smoking device shown in Figure 1, disassembled. In the method of the present invention, the seal that closes connection 150 (seal 154) is removed before the cartridge is screwed onto opening 16. After the cartridge is connected to the tube, container 32 is filled with water (the water is not shown in Figure 7) and is ready to be screwed onto opening 18 while pipe 44 is positioned in the water.

Then port 24 of tobacco cartridge 22 is removed and the coal can be lighten so that air and eventually smoke can be inhaled by the user through bit 15. It is optional to provide the container with water or with any other fluid that act as a filter as mentioned herein before.

It is an optional to provide cartridges having a diameter that corresponds the diameter of the container's upper opening so that before disposal of the cartridge, it is inserted into the fluid container to be cooled.

It should be noted that the burning products may be tobacco or tobacco mixtures. Any mixture of tobacco and other materials such as fruit molasses and other flavor materials or other herbs that are desired to be smoked are covered by the scope of the present invention. The burning material that burns the tobacco or tobacco mixture can be coal, however any other appropriate material can be used in order to establish combustion.
