Field of application of the present invention

The present invention relates to a tool, in particular a toothbrush, for cleaning teeth and/or gums of a corresponding user.

State of the art

A toothbrush is a tool for oral hygiene, which allows removing impurities, especially plaque, from teeth and gums. It consists of a toothbrush in synthetic fibres that is inserted into the mouth via a special handle, after possibly applying a dab of toothpaste thereon.

Toothbrushes for cleaning teeth and/or gums of a corresponding user are known, comprising elongated means or a handle for supporting corresponding means, or respective head, for cleaning the teeth and/or gums, of said user, having corresponding cleaning or brushing bristles, which bristles define on the whole, with their free end, a corresponding surface for engaging and cleaning, especially for brushing, said teeth.

In a known manner, said cleaning means, or head, are movably, in particular rotatably, supported by said elongated support means, and corresponding actuating means of the movement, especially the rotation, for cleaning said means, or head are provided for, as well as corresponding means for driving said movement, especially said rotation, of said cleaning means, or head.

It is known that the currently used toothbrushes with an automatic actuation, as well as those with a manual actuation, are composed of a handle connected to a head by a fitting portion. The head is provided with a plurality of bristles, generally parallel to one another and arranged perpendicularly to a planar surface of the above-mentioned head.

Electric-actuated toothbrushes were originally designed for those patients with restricted motor abilities or for orthodontic patients.

However, nowadays said electric-actuated toothbrushes are particular useful for anyone, especially for those who do not use manual toothbrushes correctly, and in any case, they make the cleaning process of teeth and/or gums more comfortable and easier, since a significant part of the work is done without substantial manual movement by the user.

In addition, besides directly performing the brushing motion, the electrical toothbrushes differ from the manual toothbrushes also in another aspect. In fact, the handle of the electrical toothbrushes is designed to house power supply batteries, a propelling motor, and corresponding motion transmission means, together with other components required to ensure the driving, which is performed manually, through corresponding push button means exposed on the exterior of said handle.

Moreover, the currently used electrical toothbrushes usually operate at low voltage, typically of 12V or less. In particular, some designs of toothbrush also use a transformer to directly supply the motor within the handle via a cable, however, most of the already-known brushes has a rechargeable battery build-in inside the handle to be held. Other electrical toothbrushes use replaceable, disposable batteries which, as the rechargeable ones, are generally located on the bottom of the handle.

Moreover, some models are designed to be of a disposable type.

According to a known and quite widespread type of toothbrush, the head, the fitting body, and the handle of the electrical or manual toothbrush are arranged along the same straight line, thus the bristles are perpendicular to the above-mentioned line. Such straight line further represents the main axis of the tool.

Disadvantageously, toothbrushes configured in this way have limited accessibility to the oral cavity, i.e. , not all points within the oral cavity are easily reachable. In addition, the efficiency of the cleaning operation is substantially reduced, since the vibrating or oscillating cleaning action of these already known electric toothbrushes does not act through the cleansing movement senses from the gum to the tooth, which are instead universally recommended by the industry professionals.

In any event, in the field, it would be highly desirable to have toothbrushes that are as comfortable and easy to use as possible, and, especially for those users who have mobility difficulties, also as streamlined as possible.

Summary of the invention

In any event, by the present invention it is desired to propose a new and alternative solution to the solutions known so far, and in particular it is proposed to obviate one or more of the drawbacks or problems referred to above and/or to satisfy one or more needs referred to above, and/or in any case felt in the art, and in particular deducible from the above.

Therefor, a tool, in particular a toothbrush, is provided for cleaning teeth and/or gums of a corresponding user, comprising elongated means for supporting corresponding means, or respective head, for cleaning the teeth and/or gums of said user, in particular having means defining a surface for engaging said teeth and/or gums, preferably in the form of corresponding brushing bristles, which preferably define on the whole, with their free end, a corresponding surface for engaging and cleaning, especially for brushing, said teeth and/or gums; especially said cleaning means, or head, being activated by corresponding means of actuation, in particular for actuating a movement, especially a rotation, of said cleaning means, or head, and corresponding means are provided for controlling said actuating means, in particular of said movement, or of said rotation, of said cleaning means, or head; characterized in that said drive means, of said actuating means, in particular of actuation of the movement, especially the rotation, of said cleaning means, or head, are in the form of corresponding automatic drive means.

In this manner, a tool, in particular a toothbrush, for cleaning teeth and/or gums is obtained, the use of which is made considerably easier, in particular for those users who have difficulties, especially mobility difficulties.

In practice, the masticatory surface FM of the tooth can be brushed both through a clockwise rotation of the head, or equally, also through a counterclockwise rotation, and in a preferred manner, it is preferred to maintain the rotation that is used on the side part of the tooth from which said masticatory surface is reached.

As can be seen from said Figs. 9 to 12, in an advantageous manner, alternatively to what has been just illustrated, said drive means 18, of said actuating means 16, in particular of actuation of the movement, especially the rotation, of said cleaning means, or head 14, i.e., said processor means 180, are configured to maintain, in particular starting from at least one corresponding signal received, in 1013, from said detecting, or sensor, means, i.e., from the angular position determined, in 1014, by the same drive means 18, of said actuating means 16, in particular of actuation of the movement, especially the rotation, of said cleaning means, or head 14, i.e., by said processor means 180, in a stop condition of the rotation of said cleaning means, or head 14, when said tool is in an angular position ranging between a predetermined upstream angle, in particular ranging between 70° and 90°, preferably equal, or substantially equal, to 80° and a predetermined downstream angle of activation of the rotation, in particular ranging between 90° and 110°, preferably equal, or substantially equal, to 100°, for the lower arch of the teeth and/or the gums, and an angular position ranging between a predetermined upstream angle, in particular ranging between 250° and 270°, preferably equal, or substantially equal, to 260° and a predetermined downstream angle, in particular ranging between 270° and 290°, preferably equal, or substantially equal, to 280° for the upper arch of the user’s teeth and/or gums.

In this manner, alternatively to what has been illustrated above, the masticatory surface Fm of the teeth can be brushed, without any rotation of said cleaning means, or head 14.

Advantageously, as can be seen from said Figs. 9 to 12, said drive means 18, of said actuating means 16, in particular of actuation of the movement, especially the rotation, of said cleaning means, or head 14, i.e. , said processor means 180, are configured to drive, in particular starting from at least one corresponding signal received, in 1013, from said detecting, or sensor, means, i.e., from the angular position determined, in 1014, by the same drive means 18, of said actuating means 16, in particular of actuation of the movement, especially the rotation, of said cleaning means, or head 14, i.e., said processor means 180, a condition of stop of the rotation of said cleaning means, or head 14, when said tool is in an angular position ranging between a predetermined upstream angle of deactivation of the rotation, in particular ranging between 180° and 200°, preferably equal, or substantially equal, to 190° and a predetermined downstream angle of deactivation of the rotation, in particular ranging between 340° and 360°, preferably equal, or substantially equal, to 350°, for the lower arch of the teeth and/or the gums, and an angular position ranging between a predetermined upstream angle of deactivation of the rotation, in particular ranging between 0° and 20°, preferably equal, or substantially equal, to 10° and a predetermined downstream angle of deactivation of the rotation, in particular ranging between 160° and 180°, preferably equal, or substantially equal, to 170° for the upper arch of the user’s teeth and/or gums.

In particular, besides the angular indications set forth above, it shall be in any case understood that the cleaning of the lower arch and the upper arch of the teeth occurs in two distinct steps, or stages, of the cleaning process, which are temporally spaced apart from one another. As regards the incisors and canine teeth or front teeth, these have a front or outer face and a rear or inner face. By assuming that a user of the tool, or toothbrush is right-handed, i.e., holding the tool with his/her right hand, for the incisors or canines of the lower arch, the front, or outer, face, corresponds to the left side Si, and the rear, or inner, face, corresponds to the right side Di of the same lower arch. Also, by assuming that a user of the tool, or toothbrush is right-handed, i.e., holding the tool with his/her right hand, for the incisors or canines of the upper arch, the front, or outer, face, corresponds to the left side Su, and the rear, or inner, face, corresponds to the right side Du of the same upper arch.

In particular, according to a preferred operational mode, the respective functioning step of the tool, or toothbrush, would continue to be operative, until the timing, i.e., the time available to complete the cleaning operation, is still ongoing, and however the rotation of the cleaning means, or head would be kept blocked.

Therefore, in a particularly advantageous manner, said drive means 18, of said actuating means 16, in particular of actuation of the movement, especially the rotation, of said cleaning means, or head 14, i.e., said processor means 180, are configured so as to actuate a corresponding, in particular predefined, cleaning process and especially defined by corresponding instructions, i.e., by a corresponding software or program, preferably housed in the memory of the same drive means 18, of said actuating means 16, in particular a corresponding process of actuation of the movement, especially the rotation, of said cleaning means, or head 14, i.e., of said processor means 180.

It shall be in any case understood that an implementation of a tool, or toothbrush, could be provided for, in which no temporal limits to perform the respective cleaning step i.e., to perform the entire cleaning of the teeth, are provided for. In particular, the user should just turn the tool or toothbrush on, for example, by using the corresponding drive means 181 , and possibly turn the tool or toothbrush off, for example, again by using the latter. In particular, and preferably, in that case the tool or toothbrush would be driven only by the sensors of position, i.e., of detection of the incline and/or the angular position of the same tool or toothbrush.

In this manner, the user is suitably informed and guided during the cleaning process.

- a tool, in particular a toothbrush, is obtained for cleaning teeth and/or gums, the use of which is made considerably easier, in particular for those users who have difficulties, in particular mobility difficulties;

- a tool, in particular a toothbrush, is obtained for cleaning teeth and/or gums, which can be suitably controlled to perform the proper actuations of the tool, in particular to perform the proper movement of the brushing action, i.e., which is adapted to implement a corresponding brushed performed in a controlled manner, in particular providing for a proper sense of action of the bristles, i.e., from the gum towards the teeth

- by virtue of its efficiency, it allows for reduced cleaning times, without decreasing its efficiency;

- it is possible to automatically activate the cleaning of the respective arch of the user’s set of teeth with a proper movement, or sense of rotation, of said cleaning means, or head; - the proper brushing action from the gum towards the end of the teeth is achieved for each side of the respective dental arch of the user;

- it is possible to actuate cleaning heads that are not in axis with the handle of the same tool;

- it is avoided to create an excessive angulation, and said inclined transmission means, thus achieving less mechanical stress of the components;

- it is possible to replace already-used cleaning means, or head with new cleaning means, or head and thus continuing using the tool;

- the masticatory surface of the teeth and/or the gums can be brushed, without rotation of said cleaning means, or head;

- damage is avoided, preventing an unwanted rubbing, during the cleaning operation, of the parts opposite those that are subjected to the cleaning or cleansing, in particular the cheek inner part or the tongue.

- an undesired build-up of material between said covering means and said cleaning means, or head, is avoided.
