CN2737323Y - Electric brush for interproximal space - Google Patents

Abstract

The utility model discloses a new type electric brush for interproximal space. The electric brush for the interproximal space uses a battery as the power to drive a micromotor, and the front half segment of the center of a motor rotor is a tubular hollow chamber, the tubular hollow chamber is used to contain the built-in part of a cleaning head, and the hollow chamber and the cleaning head are mutually tabled to drive through a gear wheel. A motor cap restricts the built-in part of the cleaning head to make the exposed part of the cleaning head extend through the circular hole of the center of the front part. The exposed part of the cleaning head is a slender cone which can extend in the interporximal space which is formed after gingivae are recessed to rotate to remove various pathogenic objects in the interproximal space. When the electric brush for the interproximal space is started up, the rotational speed of the cleaning head can be adjusted freely.

Description

The electric interdental brush

This utility model belongs to daily oral hygiene appliance.

Known daily oral hygiene appliance mainly contains manual hand brush, toothpick, dental floss and electric toothbrush four classes at present, wherein universal with the application of manual toothbrush, cleaning and health care effect to the oral cavity is performed meritorious deeds never to be obliterated, but, the bristle of manual toothbrush contacts because being planar with facing and teeth space, so it is be longer than the cleaning facing, but then poor because of cleaning effect more difficult to get access for teeth space; Toothpick matter is hard, is longer than and rejects impaction material in the teeth space, but then be difficult to cleaning for soft dirt, bacterial plaque in the teeth space; Dental floss can strike off the soft dirt in the teeth space, but when using dental floss, its process is tediously long, cumbersome, poor efficiency, unhygienic; The form of electric toothbrush and functional characteristics are compared with ordinary toothbrush and be there is no essential distinction---can not clean teeth space preferably equally.Because of these oral hygiene appliances commonly used all can not clean teeth space efficiently, easily, cause delays such as food debris, soft dirt, bacterial plaque are often arranged in the teeth space, make the sickness rate of oral pathology such as tooth proximal surface dental caries, gingivitis, periodontitis high for a long time, damaged everybody's oral health, have much room for improvement.

The purpose of this utility model provides a kind of novel oral hygiene appliance, overcomes the drawback that traditional oral hygiene appliance can not clean teeth space effectively, meticulously, can stretch into the teeth space high-efficiency cleaning, thereby safeguard dental health better.

This utility model is achieved in that with battery-operated micromotor, the rotation of motor is changed into the rotation of cleaning head through gear drive.Cleaning head and tooth contact portion are elongate tapered, can stretch into easily in the teeth space that forms behind the gingival atrophy, remove in the teeth space in the rotation process and the soft dirt on the tooth proximal surface, bacterial plaque etc., reach the purpose of cleaning teeth space.

Because the electric interdental brush can enter cleaning in the teeth space easily, remove food debris, soft dirt, bacterial plaque in the teeth space fully, simultaneously brush paste the facing rotation more can the rapid cleaning facing, so can finish cleaning better to tooth than manual toothbrush, toothpick, dental floss.Except that being suitable for adult that gingiva generally shrinks back, to the uneven person of crowded dentition, accept oral cavity orthodontic treatment person, mouthful in multiclass special populations such as the person that has the fixed restoration, upper extremity exercise is slight obstacle person, traveller, more can bring into play its advantage, satisfy their special oral cavity cleaning needs, reduce the sickness rate of tooth proximal surface dental caries, gingivitis, periodontitis etc.

Below in conjunction with accompanying drawing this utility model is further specified.

Accompanying drawing 1 is a vertical section of the present utility model structural map.

1, battery case 2, battery 3, switch 4, micromotor

5, motor base 6, motor medicated cap 7, cleaning head

Battery case in Fig. 1 (1) is cylindrical, its upper end with motor base (5) between to be threaded; Micromotor (4) rotor central authorities are entity structure near a side of motor base (5), and be a blind pipe near a side of motor medicated cap (6), there is suitable blind pipe long axis direction evenly to arrange the strip projection of example on the blind pipe wall, the proper tabling of strip projection that distributes on the built-in part outer surface of these projections and cleaning head (7), transmission whereby.The exposed parts of cleaning head (7) is more elongated taper shape, is about 15mm.Rounding off between the built-in part of cleaning head (7) and the exposed parts.Motor medicated cap (6) is half elliposoidal of smooth outer surface, and there is circular hole in its outstanding front central authorities, and the diameter of this circular hole is less than the diameter of the built-in part of cleaning head (7), but the while is greater than the diameter of cleaning head (7) exposed parts thickness.Between motor medicated cap (6) and the motor base (5) to be threaded.Approximately at an angle of 90, and the built-in part of cleaning head is a whole and continuity of keeping straight on mutually with exposed parts between battery case (1) and the cleaning head (7).

Claims (5)

1, a kind of electric interdental brush, by battery case, battery, switch, micromotor, motor base, the motor medicated cap, cleaning head constitutes jointly, it is characterized in that: battery case is cylindrical, with between the motor base to be threaded, miniature electric machine rotor central authorities are a tubular cavity near a side of motor medicated cap, be used for holding the built-in part of cleaning head, between motor medicated cap and the motor base to be threaded, the front end centre of motor medicated cap has circular hole, the exposed parts of cleaning head stretches out outside the motor medicated cap through this hole, and switch then is connected between battery and the micromotor by lead.

2, electric interdental brush according to claim 1, it is characterized in that: the strip dentation that is distributing consistent equably on the sidewall of the forward tubular cavity of miniature electric machine rotor central authorities with the tube wall long axis direction, these projections and the proper tabling of strip projection on the built-in part outer surface of cleaning head, the structure of formative gear transmission.

3, electric interdental brush according to claim 1, it is characterized in that: the diameter of the built-in part of cleaning head is obviously greater than the diameter of exposed parts thickness, and transition between the two is non-step, but rounding off little by little, motor medicated cap front end centre Circularhole diameter is less than the diameter of the built-in part of cleaning head, and the cleaning head exposed parts is the gradually thin taper that is about 15mm of terminad, and makes an appointment with at an angle of 90 between the battery case.
