Description

 The invention relates to the field of personal hygiene and sanitary-hygienic accessories, and in particular to tools for cleaning removable lower and upper dentures.

 The invention may find application in dentistry for the treatment of vestibular and chewing surfaces of anterior teeth and interdental spaces in order to prevent the occurrence of gingival pockets and the development of periodontal disease.

A known tool for hygienic treatment of the oral cavity, containing a handle with an electric drive and a head of elastic material with a cleaning element (see RF patent, MKI ⁶ , 2123822, A 61 C 17/00, A 46 B 9/04. A method of hygienic processing of the oral cavity and a tool for its implementation / Declaration 14.12.93, publ. 27.12.98.).

 The disadvantages of the known tool, when used for cleaning dentures, are: low quality cleaning of dentures associated with the design of a cleaning element that is not able to penetrate and clean all kinds of recesses in dentures; low reliability and high cost due to the complexity of its design; high duration of cleaning dentures; quick wear of cleaning elements.

Closest to the proposed device in terms of essential features is a toothbrush containing a head in the form of a hollow chamber made of an elastic material with cleaning elements filled with a liquid agent (see RF patent, MKI ⁶ , 2039486, A 46 B 9/04. Toothbrush / Declared 02.06.92, publ. 20.07.95, Bull 20).

 The disadvantages of this brush, compared with the claimed, when using it for cleaning dentures, are: the inability to clean the inner surfaces of the lower and upper removable dentures and cleaning most of the outer surfaces of the upper removable dentures due to the absence of transverse U-shaped concave surfaces with cleaning elements; low head life due to quick wear of cleaning elements; low efficiency of cleaning from petrified deposits.

 The technical result created by the invention consists in the ability to offer the mass consumer a reliable and cheap brush for quick cleaning of removable dentures. The advantages of the proposed brush are as follows: quick cleaning of the palatine areas of the upper dentures, gingival cavities and other surfaces of the dentures; high efficiency of cleaning from petrified deposits; high head life.

 This result is achieved in that the toothbrush containing the head in the form of a hollow chamber made of an elastic material with cleaning elements filled with a liquid agent has several transverse U-shaped concave surfaces with cleaning elements, most of the rest of the head surface is covered with cleaning elements, has an opening in the wall of the hollow chamber connected to the handle, to the end of which on the side of the hollow chamber an elastic diaphragm is connected rigidly, connected to the oscillation generator through the rod, mi in the handle.

 The presence on the head of transverse U-shaped concave surfaces with cleaning elements allows you to clean the gingival surfaces of dentures, as well as other hard-to-reach areas. The presence of several such U-shaped concave surfaces on the head increases its service life.

 The presence of cleaning elements on most of the rest of the head surface, free of transverse U-shaped concave surfaces, allows the use of these cleaning elements to clean certain areas of the dentures, for example, the palatal surface of the upper denture. This increases the life of the head as a whole.

 The presence of a hole in the center of one wall of the hollow chamber is necessary in order for the vibrational vibrations from the generator of vibrational vibrations to act most uniformly through the liquid agent on the entire surface of the hollow chamber covered with cleaning elements. Just the presence of a hole in the wall of the hollow chamber is necessary for pouring a liquid agent into it.

 The vibration generator through the elastic diaphragm in the handle and through the liquid agent acts on the walls of the hollow chamber, causing vibrational vibrations of the cleaning elements, which significantly accelerate the cleaning process, especially from petrified deposits.

 The implementation of the generator of vibrational vibrations in the form of an electric drive of reciprocating movements with a frequency of an external power supply network allows us to extremely simplify its design and provide a given amplitude of vibrational vibrations of the cleaning elements.

 Figure 1 shows a General view of the brush for dentures, a longitudinal section, figure 2 is a General view of the head, left view.

 The device comprises a head made in the form of a hollow chamber 1 of an elastic material with cleaning elements 2, for example, in the form of a bristle-pile coating. In the hollow chamber 1, U-shaped concave 3 and convex 4 surfaces are alternately arranged. The hollow chamber 1 is filled with a liquid agent and has an opening 5 with a tubular element 6, which is hermetically connected to the handle 7. An elastic diaphragm 8 is attached to the end of the handle 7, which is rigidly connected through the rod 9 to a vibration generator 10, which is connected to an external AC voltage network ( conditionally not shown).

 The proposed device operates as follows.

 After turning on the device in an external alternating voltage electric network, the vibration generator 10 through the rod 9 and the elastic diaphragm 8 causes vibrational vibrations, with the frequency of the external power supply, of the liquid agent filling the hollow chamber 1. These vibrations, through the elastic walls of the hollow chamber 1, cause vibrational vibrations of the cleaning elements 2 located on the outer surfaces of the hollow chamber 1.

 A denture brush is used as follows. The convex surfaces 4 of the brush head are inserted into the gingival region of the prosthesis and brushing movements are carried out with a brush. Part of the prosthesis area, including the vestibular, chewing, and palatine surfaces, is inserted into the concave surface of the 3 brush heads, and then brush movements are carried out by the brush. The palatine surfaces of the upper denture and some other areas of the prosthesis can be cleaned with the end parts of the brush head or the convex surfaces of the 4 heads.

 This brush allows you to customize it for removable dentures of an individual user, to clean dentures from petrified deposits, and also provides softness and springy cleaning mode. The brush head has an extended service life.
