| 1. | A razor handle with cleaning water jets, for razor heads cartridges of the one or two or three type blades comprising: a) An adaptor, to fit standard faucet openings, in a form of a semi spherical ball made of hard elastic material, adapted on the handle, to connect the razor handle to the faucet ; b) A hollow handle used as a water carrier/tube, allowing the flow of the water; c) A security valve integrated into the base of the handle, to break the water pressure in case of a too strong water flow from the faucet; d) Exits for the water, in a form of small holes or tubes that will build the water pressure forming small jets of water directed on the razor blades. The water jets by passing inwardly through said passages in the razor head will flush soap and shaving residue accumulated in and around the blades. |
| 2. | A razor handle with cleaning water jets, for razor heads cartridges of the one or two or three type blades comprising: A water connector and jets system integrated in the razor handle; a) An adaptor, to fit standard faucet openings, in a form of a semi spherical ball made of hard elastic material, inside the handle, to connect the razor handle to the faucet; b) A security valve integrated into the base of the adaptor, to break the water pressure in case of a too strong water flow from the faucet; c) An inside system of micro tubes made of plastic or metal connected to the adaptor base, delivering the micro water jets to the razor head cartridge. d) A razor handle made of two hollow parts, which will receive inside the complete cleaning system and to be closed/snapped one in top of the other to form the final structure of the razor. |
| 3. | A razor handle with cleaning water jets, with quick water connector and jet system; a) A small water adaptor, in a male/female type, about the same as used for garden hose quick connectors, fitted on the handle. This female adaptor is made in such a way that when opening the water faucet, the pressure closes the system, preventing the male part to get out of the female part adapted on/in the razor handle. When the faucet is closed the water pressure go down, the male member is automatically released, liberating the razor handle. b) A system for connecting the female adaptor to the faucet, fitted at the opening of the faucet, and used as the male connector for the female part adaptor fitted on the razor handle. c) A hollow handle used as a water carrier, allowing the flow of the water; d) A security valve integrated into the base of the adaptor, to break the water pressure in case of a too strong water flow from the faucet; e) Exits for the water, in a form of small holes or tubes that will build the water pressure forming small jets of water directed on the razor blades. The water jets by passing inwardly through said passages in the razor head will flush soap and shaving residue accumulated in and around the blades. |
| 4. | A razor handle with cleaning water jets, with Oring water connector and jet system integrated in the razor handle; a) A small water adaptor, in a male/female type, fitted inside the handle. This female adaptor is a same as No. 3 but have no blocking system integrated and need to be pressed against the faucet mouth when opening the water faucet. The 0ring, on the male adaptor, water proofing the connection. b) A system for connecting the female adaptor to the faucet, fitted at the opening of the faucet, and used as the male connector for the female part adaptor system fitted inside the razor handle. d) A security valve integrated into the base of the female adaptor, to break the water pressure in case of a too strong water flow from the faucet; e) Exits for the water, in a form of small tubes, connected to the female connector that will build the water pressure forming small jets of water directed on the razor blades. The water jets by passing inwardly through said passages in the razor head will flush soap and shaving residue accumulated in and around the blades. |
In razors of this type, the hairs cut off by the blades, and the foam used for shaving, accumulate between the razor blades and between the blades and body of the cartridge, thus very considerably reducing the efficiency of this type of mounting. It should also be noted that so-called"thick"foams very quickly obstruct the space formed between the blades and this occurs even before the user finishes shaving. Rinsing these types of cartridges under the tap is effective only to a very limited extent.
Also it is proved that spacing between the blades of the razor cartridge is in direct connection with the quality of the shaving. This system allows a smaller spacing of the blades such increasing the quality of the shaving.
The present invention seeks to overcome these disadvantages and to provide a simple and effective cleaning device for razor cartridges.
The designs and ergonometrics of the invention can easily be changed or adapted without affecting the basic purpose of the invention that is to clean effectively and quickly, with water jets and less water waste, the razor head cartridge.
The spot of the various adaptors on the handle can also be changed easily, suiting the needs of the future manufacturers.
In claims No. 1 and No. 2 the use of the invention is simple: the adaptor is placed under the exit of the tap water and firmly pressed with one hand. With the other hand we open the faucet to rise a reasonably water pressure in the system cleaning water jets without provoking side splashes. The security valve allowing a large margin of water pressure without splashes.
In claim No. 3 the invention is based in an adaptor that will need a part fitted on the faucet. It will be use in extreme cases of blades clogging, generally because the razor cartridge can be built with a smaller space between the blades. This system can also be built on the schema of claims. 2 a full integrated system.
All the systems can be mixed together or interchanged suiting the needs of manufacturing or fashion designs.
The foregoing and advantages will appear from the following drawings, which form a part hereof, and in which is shown by way of illustration specific embodiments in which the invention may be practiced. It is to be understood that other embodiments may be utilized and that structural changes may be made without departing from the scope of the invention. In the accompanying drawings, like reference characters designate the same or similar parts throughout the several views.
The following detailed description is, therefore, not to be taken in a limiting sense, and the scope of the present invention is best defined by the appended claims.
