Abstract

The technical solution relates to dentistry and can be used in cleaning teeth and interdental gaps, and also in polishing teeth and massaging gums. The technical result consists in, during the cleaning of teeth, casting plaque and food particles off of a brush and onto a hood and buccal mucosa in order to avoid brushing said plaque and food particles back into the interdental gaps. An electromechanical device for maintaining oral hygiene contains a tooth processing unit (1) which is mechanically connected to an electric drive which is installed in a housing (2) of a device handle. The tooth processing unit (1) is in the form of a shaft (4) having removable heads (5), said shaft being partially installed in the handle housing (2) and having the ability to rotate. The heads (5) are affixed on the external part of the shaft (4), which protrudes out of the housing (2). The end of the portion of the shaft (4) which is positioned in the handle housing (2) comes into contact with a corresponding output of the electric drive, the electric input of which drive is connected to the output of a battery (8) which is also installed within the handle housing (2). A hood (6) is provided on the handle housing (2) above the external portion of the shaft (4) which protrudes out of the handle housing (2), said hood corresponding to the length of the protruding portion of the shaft (4) with a head (5) secured thereon, and made in the form of a profiled plate with an inner longitudinal protrusion (7). The height of the protrusion (7) allows same to come into contact with the operating surface of a removable head (5) installed on the shaft. The present invention additionally provides for design variants.

Description

ELECTROMECHANICAL DEVICE FOR SECURITY

Mouth Hygiene

The claimed technical solution relates to the field of dentistry and can be used for brushing teeth and interdental spaces, as well as polishing teeth and massage gums.

State of the art

From the prior art, an electromechanical toothbrush is known, consisting of a handle housing with a microelectric drive located in it and a working part in the form of two counter-rotating cleaning elements connected to the microelectric drive by parallel drive axles closed from the outside of the casing equipped with nozzles in the form of removable cylindrical brushes or cylindrical tuberous rollers (RU, 14217829 U1).

The design of this device does not provide a means for dropping bristles from bristles when brushing plaque teeth and food particles. As a result, the quality of cleaning is reduced. An electromechanical toothbrush is also known from the prior art, consisting of a handle body with a micro-electric drive located in it, a neck with a drive axle installed in it, and a working head with a crown brush (see, for example, hpp: //www.braun-oral-b- professional-care-500-i-d16-513u.html). The design of this known device also does not provide a means for dropping from the bristles of the brush when brushing teeth plaque and food particles, and, in addition, a relatively small area of the cleaning element - the crown brush requires the skills of accurate positioning on the tooth surface being cleaned.

Disclosure of technical solution The objective of the claimed technical solution is to develop an electromechanical device for ensuring oral hygiene, the design of which provides for the possibility of high-quality cleaning of the surface of the dentition and interdental spaces by dropping plaque and food particles from the brush when brushing teeth.

The technical result of the proposed technical solution is to ensure that the dentists recommend the vertical direction of movement of the cleaning element from the gums, as well as cleaning the working element from plaque and food particles during brushing to prevent rubbing back into the interdental spaces.

The technical result is achieved by the fact that in the electromechanical device for ensuring oral hygiene containing a tooth processing unit, mechanically connected with an electric drive installed in the handle body of the device, according to the claimed technical solution, the tooth processing unit is configured as rotatable and partially placed in the shaft handle housing with removable nozzles fixed to its outer part protruding from the handle housing, the end face being placed inside and the handle housing of the shaft part is made in contact with the corresponding output of the electric drive, which is connected by its electric input to the output of the battery, also installed in the handle housing, while the outer part of the shaft protruding from the handle housing on the handle housing a visor is made corresponding to the length of the protruding part of the shaft with the nozzle and formed in the form of a profile plate with an internal longitudinal protrusion with a height that makes it possible to touch the surface of the removable nozzle mounted on the shaft.

Nozzles can be made in the form of a cylindrical brush or rubber sleeve.

The electric drive can be equipped with a unit for changing the direction of rotation of the shaft. It is advisable that the electromechanical device be equipped with an electrically connected with the battery light indicator of the direction of rotation of the shaft, functionally organized as a creeping line and made in the form of an annular optical element located on the outer surface of the handle housing from the side of the protruding outer part of the shaft.

Variant of the technical solution

The technical solution is illustrated by graphic materials. Figure 1 is a General view of an electromechanical device for providing oral hygiene.

Figure 2 is a view A of figure 1.

In the claimed technical solution, the nodes, blocks and elements included in it are indicated by the following positions: 1 - block (dental treatment); 2 - case (device handles); 3

- electric motor (electric drive); 4 - shaft (block 1 tooth processing), 5 - nozzles (in the form of a cylindrical brush); 6 - visor, 7 - ledge (longitudinal visor 6); 8 - battery; 9 - toggle switch (turning on the electric motor 3); 10 - indicator (direction of rotation of the shaft 4); 1 1 - trajectory (rotation of the peripheral sections of the cylindrical brush).

An electromechanical device for ensuring oral hygiene contains: a tooth processing unit 1 mechanically connected to an electric motor 3 (electric drive) installed in the housing 2 of the device handle, made, for example, in the form of a DI1-2 s microelectric motor (see, for example, http: // modelist - konstruktor.eom / v_mire_modelejyvy-priobretaete-mikroelektrodvigatel-kak- vbrat-luchshii); a shaft 4 mounted with the possibility of rotation and partially placed in the handle housing 2 with a removable nozzle 5 in the form of a cylindrical brush of bristles or in the form of a polishing rubber sleeve (not shown in Fig. 1), fixed to the shaft part 4 protruding from the handle body 2 of the device; moreover, the end face of the shaft part 4 placed in the cavity of the housing 2 of the handle is made in contact with the corresponding output of the electric motor 3, with its electrical input connected to the output of the battery 8, made in the form of a corresponding power source of the AAA Duracell type (see, for example, http: / www.http: //duracell.ru/ru-ru/category/duracell-rechargeable/AAA), also installed in the housing 2 handles; at the same time, a visor 6 is made over the outer part of the shaft 4 on the handle housing 2 (mainly integrally with the handle body 2), corresponding to the length of this part of the shaft 4 and the nozzle 5 and formed in the form of a profile plate with an internal longitudinal protrusion 7 with a height that provides the possibility of touching the surface of the working elements (brush bristles) mounted on the shaft 4 of the removable nozzle 5. In addition, the cavity inside the housing 2 of the handle of the device from the outside can be closed with a protective waterproof rubber ring (not shown in Fig. 1) with an opening for the shaft 4.

The electric motor 3 is equipped with a circuit (not shown in Fig. 1) for changing the direction of rotation of the shaft 4 (see, for example, http://fictionbook.ru/author/dionJovin/sozdaem_robota_androida_svoimi_r ukami / read_online.html? Page = 5), while the toggle switch 9 is made in the form of a reversing switch (see, for example, http://www.dkc2.ru/shop_show_374413.html). To ensure ease of use, the electromechanical device can be equipped with an electrically connected with the battery 8 light indicator 10 of the direction of rotation of the shaft 4, functionally organized as a creeping line and made in the form of an annular optical element located on the outer surface of the handle body 2 from the side of the protruding outer part shaft 4.

The work of the claimed technical solution is as follows.

First, for carrying out the procedure for brushing the teeth, as well as the interdental space on the shaft 4, nozzles 5 are installed in the form of a cylindrical bristle brush. Accordingly, for the tooth polishing procedure, nozzles 5 are mounted on the shaft 4 in the form of a polishing rubber sleeve, the diameter of the outer surface of which is chosen so that this surface practically does not touch the protrusion 7 of the visor 6, or, in extreme cases, slides along the visor 6.

Using the toggle switch 9 include an electric motor 3, a rotating shaft 4 and, accordingly, nozzles 5, and enter the device into the oral cavity for contact of the bristles of the brush with teeth. In this case, the protrusion 7 of the visor 6 cleans food particles adhering to the brush bristles, and visor 6 provides protection against injuries of the cheek mucosa. It should be noted that the design of the device in accordance with the requirements of dentists provides for the rotation of the nozzle 5 from the gums (sweeping rotation), and at the same time, the angle of inclination is changed, which ensures cleaning of the interdental space.

It is obvious that during rotation of the nozzle 5 it is visually difficult to determine the direction of its rotation. Therefore, for ease of operation, a light indicator 10 of the direction of rotation of the shaft 4 can be used in the device, functionally organized as a creeping line and made in the form of an annular optical element located on the outer surface of the handle body 2 from the side of the protruding outer part of the shaft 4. In the direction of movement of the light spot along the surface of the indicator 10, the direction of rotation of the nozzle 5 is determined. It is possible to control the direction of rotation directly in the process of brushing teeth according to the movement of the light spot in the mirror.

Recommended by dentists, the main direction of toothbrush movement when brushing teeth is sweeping from the gums. Reproducing it in practice is difficult. The movement of a traditional toothbrush when brushing your teeth is recommended: for the upper teeth - from top to bottom and for the lower - from bottom to top, that is, vertically from the gums. The proposed device for providing oral hygiene (electromechanical toothbrush) ideally simulates sweeping movements from the gums. The bristles of the nozzle 5, on the one hand, are covered by a screen - a visor 6, which protects the mucous membrane of the cheeks from touching the rotating brush 5. The feature of the protective screen-visor 6 is a pronounced protrusion 7 located in the center along the entire inner surface of the visor 6. Its main and important appointment: during rotation of the brush - brush, the ends of the bristles hit an obstacle, spring together and discard the plaque on them towards the mucous membrane of the cheeks or in the oral cavity, returning clean to the surface of the teeth. Advantages: easily feasible vertically sweeping brush movements that allow you to qualitatively "sweep" food debris from the interdental spaces without rubbing them back, as happens with other toothbrushes; an opportunity to use rubber polishers instead of a brush - brush - nozzles for polishing tooth enamel to a mirror shine; Combining bristles with rubber inserts, gum massage can be carried out simultaneously with brushing your teeth.

The device can be turned on with a common button and start the rotation of the nozzle 5 in any direction, while the direction of rotation of the nozzle 5 is visually duplicated by the running light spot of the indicator 10. The rotation is carried out, say, for 15 seconds, then, after the beeper sounds, the reverse is triggered. And so this will happen until you press the button again (that is, to disable the rotation of the nozzle 5). It is better to turn on the device after applying toothpaste to the brush and placing it in the oral cavity, in order to avoid spraying the paste. The signal of the beeper will make it possible to carry out better brushing of teeth in segments, which will undoubtedly improve the quality of brushing. The signal can serve as a timer to control the duration of cleaning.
