Description

FIELD OF THE INVENTION The invention relates to sanitary and hygiene supplies.

Currently known are tools for cleaning teeth in the form of a toothbrush consisting of a handle and a head (working part), on which tufts of bristles, arranged in rows, are attached. The available toothbrushes do not fully meet modern requirements of oral hygiene of a person, since the time required for cleaning reaches 5 minutes. In this case, the design of the brush does not program its movement from top to bottom when cleaning the upper teeth and from bottom to top when cleaning the lower teeth and horizontal movement of the brush when cleaning the horizontal surfaces of the teeth. For the prototype we take a toothbrush on the author. St. No. 27765. A toothbrush consists of a groove inside which the discs with bristles attached to them rotate. The movement of the disks is obtained from the rotating spindle through gears. The disadvantage of this toothbrush is that the movement of the bristles does not meet the recommendations

dentists, and the horizontal surfaces of the teeth are not clean. Only one set of teeth, upper or lower, is cleaned at a time, which increases the time for cleaning the teeth.

The purpose of the invention is to improve the quality of brushing teeth by simultaneously cleaning the teeth of the front, back and chewing surfaces of the upper and lower teeth.

FIG. 1 shows the brush, a general view; in fig. 2 - the same, left view; in fig. 3 - electric brush; in fig. 4 - brush, in a perspective view.

The toothbrush includes a housing 1, a shaft 2, a tape 3 with bristles, a comb 4, a shaft 5, a comb 6, a tape 7 with bristles, a tube 8 made of springs with the possibility of bending material, a shaft 9 made of springs with the possibility of bending material, nut 10, gear 11, shaft 12, gear 13, box 14, handle 15, bevel gear 16, shaft 17, gear 18, shaft 19, roller 20, shaft 21, roller 22, shaft 23, roller 24. shaft 25 , roller 26, shaft 27, gear

28, bevel gear 29, housing 30, bevel gear 31, gear 32, shaft 33, roller 34, roller 36, shaft 37, roller 38, shaft 39, gear 40, shaft 41, roller 42, bevel gear 44, tube 45, made of a spring-bending material with the possibility of bending, a roller 46, made of a spring-loaded q. possibility of bending the material, a nut 47, a gear wheel 48, an electric motor 49.

The device works as follows.

In two buildings 1 and 30 of flexible material, which are mounted on tubes 8.45 in box 14 with grooves nuts 10, 47, there are flexible shafts 2, 5, 19.21, 23.25, 27, 33, 37, 39, 41. On flexible shafts there are rollers 20, 22, 24, 26, 34, 36, 38, 42. On drive shafts 17,27,33,41 there are gears 18, 28, 32, 40 as well as rollers whose positions are not indicated . In each case 1.30 on three shafts on one side and three shafts on the other hand in a checkerboard order on rollers there are tapes with bristles 3, 7. The bend of tapes with bristles is achieved by identical combs 4, 6 installed in cases 1, 30. the toothbrush is carried out from the handle 15 or the motor 49.

We press the tubes 8 and 45 with our fingers and bring them together for a minimum distance. The tubes 8 and 45 are brought together because they are made of spring material with the possibility of bending. Cases 1, 30 are placed in the mouth, their internal cavity is preliminarily covered with toothpaste. We weaken the pressure on the tubes 8 and 45 with fingers. Cases 1 and 30 pull over the gums. The handle 15 is started to turn or the motor 49 is turned on. The movement from the handle 15 is transmitted to the shaft 12 and gear 13. The rotation is transmitted from gear 13 to gears 11 and 48. Then from gear 11 through shaft 9 to bevel gears 44 and 32. From bevel gear 44 the movement is transmitted to gear 40, with which shaft 41 is driven to rotate. Drive rollers (whose positions are not shown) are equipped with rotating belts with bristles 3. Rollers with bristles are supported by 3 rollers 42, 37, which rotate freely on shafts 2.39 . From the bevel gear 32, the gear 31 rotary shaft 33 is rotated, on which rollers are fixed (position not shown) which drive the belts with bristles 7 in rotation. Ribbons with bristles 7 support rollers 34,
