Description

Two-axle electric toothbrush

This utility model relates to people's toothbrush used in everyday, it is widely used in child, the adult of all ages and classes, before the back of getting up, sleep, and brush teeth after meal, remove in the teeth space food debris of outside and facies occlusalis dentis, bacterial plaque etc. in the tooth, in case food rots, antibacterial corrodes tooth, also play simultaneously the massage gingiva, promote the gingiva blood circulation, promote the health care instrument of periodontal tissue's health.

As everyone knows, for a long time, people are accustomed to using traditional ordinary toothbrush, rely on the thrust of hands to brush teeth, still, most of people are difficult to grasp correct method for brushing teeth, action and exert oneself size and uniformity, especially child, old man and patient are all the more so, so, many oral pathology patients, because method for brushing teeth and action are incorrect, and cause symptoms such as gingival hemorrhage, atrophy even dental wedge are damaged, in addition, rely on the hands application of force to brush teeth, not only require great effort but also time-consuming, efficient is very low.

Ceng Jin has the people that the bristle of ordinary toothbrush is lined up 5 bundles, 1 row totally two row, drive worm and gear by micro machine, drive 10 pinions respectively, drive 10 bundle bristles then and rotate around the axis of itself separately, because the restriction of gear arrangement position, the direction of rotation of adjacent brush pieces is opposite.When brushing teeth, bristle with face that tooth contacts on rotatablely move as the plane, will produce horizontal teeth space direction, contrary teeth space direction motion, bristle is horizontal, the motion of reverse gingiva, can produce friction, even contusion gingiva, tooth, cause gingival atrophy, diseases such as dental wedge is damaged, simultaneously laterally, reverse brushing teeth can also be with food debris, bacterial plaque is brushed advance the junction of tooth and gingiva--in the gingival sulcus, because this motion mode of brushing teeth does not meet the action of perpendicular brush rules model, thus unfavorable to the health care of tooth and gingiva, in addition, requirement by the health of brushing teeth, the toothbrush operating period must not surpass half a year, and 10 bundle bristles are thrown off replacing, very trouble respectively from 10 gears connect.

Recently also the someone attempts to reform audaciously, bristle is formed a Cylinder, bristle all rotates with the Cylinder central shaft, can realize that tooth erects the brush method, but after the Cylinder bristle has been brushed upper teeth and gingiva, must change rotor shaft direction by toggle switch, could brush lower teeth and gingiva again, so also very time-consuming, and quite bother, moreover bristle that Cylinder is arranged and tooth or gingiva contact surface are too little again, and often needing for several times could be tooth and gingiva outwash along periodontal.

In view of this, the purpose of this utility model is the defective that exists at above-mentioned existing electric toothbrush, proposes a kind of twin shaft electric toothbrush.It is bristle to be formed two longitudinal profiles be the spiral revolving body that garden arcuation, horizontal section are garden shape, bristle rotates with upper and lower two bristle axles, brush is moving from the gingiva to the facies occlusalis dentis, it is for unidirectional current by aneroid battery, three gears of micro motor for driving, make two bristle axle backward rotation, so bristle only need move once along periodontal, last lower gum and dental surface can both have been brushed.The longitudinal profile of the spiral revolving body that bristle forms is the garden arcuation; on the one hand near tooth and gingival contour; be convenient to remove teeth space, gingival sulcus etc. and locate food debris, bacterial plaque; enlarged the contact surface of bristle and tooth gingiva on the other hand; and brush power is evenly distributed, helps the massage of gingiva greatly and the protection of oral mucosa.In addition, adopt between two bristle axles and two rotating shafts to removably connect, be convenient to the replacing of bristle, the bristle (bristle non-working surface) of bristle revolving body diameter 2/3 height is hidden by brush body, avoids the oral mucosa that rubs.This electric toothbrush is laborsaving, save time, the efficient height, and operation is also convenient, and volume is little, simple in structure, cheap simultaneously.

In order to realize the purpose of this utility model, this utility model comprises: brush body 1, bristle 2, micro machine 3, on and off switch 4, it is characterized in that: be provided with the rotating shaft 5 and 6 of two supports in brush body 1 dead eye, be provided with an end bearing in brush body 1 front end dead eye, the bristle axle 7 and 8 that the other end links to each other with 6 with rotating shaft 5 respectively in the mode of removably connecting, be provided with the tumbler gear 9 that is connected with rotating shaft 6, be provided with micro machine 3 on the pinion 10 that is connected of axle, be provided with rotating shaft 5 and be connected, simultaneously again with tumbler gear 9, the spool gear 11 of pinion 10 engagements, bristle 2 is formed two longitudinal profiles and is the garden arcuation, horizontal section is the spiral revolving body of garden shape, be connected on bristle axle 7 and 8 micro machine 3, tumbler gear 9, pinion 10, spool gear 11 and power supply all are supported in latter half of in the brush body 1 hermetically.

Further feature of the present utility model is: the first half of brush body 1 covers in the back side of spiral revolving body bristle 2 and by the two sides of the back side to revolving body diameter 2/3 height.

Fig. 1 is vertical sketch map of an embodiment of this utility model.

With reference to Fig. 1, it is as follows to be described in detail an embodiment of the present utility model:

Stir the on and off switch 4 that is exposed at outside the brush body 1, micro machine 3 inhours are rotated, go up the pinion 10 that connects, drive spool gear 11 and clockwise rotate through 3 of micro machines, drive bristle axle 7 through rotating shaft 5, bristle 2 rotates from top to bottom facing to upper teeth and gingiva on the bristle axle 7, meanwhile, spool gear 11 and tumbler gear 9 engagements, through rotating shaft 6 bristle axle 8 is rotated, the bristle 2 on the bristle axle 8 rotates from top to bottom facing to lower teeth and gingiva.

When brushing teeth, one hand is held brush body 1 rear portion, bristle 2(garden arc on the bristle axle 7 is vertically arranged) facing to upper teeth and gingiva, and allow bristle 2 keep brushing occlusal surfaces of teeth from last gingiva at every turn, again because the distance of 8 on bristle axle 7 and bristle axle goes up the lower teeth height by common people determines, for example: Toothbrush for adult two distance between axles adopt 12.5 millimeter, child's toothbrush is decided by child age, so the bristle 2(garden arc on the bristle axle 8 is vertically arranged) just in time facing to lower teeth and gingiva, bristle 2 brushes occlusal surfaces of teeth from lower gum, as long as move brush body 1 once along periodontal, all gingivas and tooth can both be by vertical method brushes one time, and unlike single brush wheel electric toothbrush, brushed upper tooth and gingiva after, also necessary toggle switch, make bristle axle backward rotation, brush lower tooth and gingiva again, not only time-consuming but also bother.

Bristle axle 7 and 8 is that the cold drawn axle top casting one deck plastic layer by 1.5 millimeters of Φ constitutes, and bristle 2 one ends of thin nylon yarn are to cast in the plastic layer, bristle 2 constitutes longitudinal profile and is the garden arcuation, horizontal section is the spiral revolving body of garden shape, bristle axle 7 and an end bearing of 8 are in brush body 1 front end plain bearing bore, the other end laterally connects the external part of corresponding rotating shaft 5 and 6 respectively with taper pin, owing between bristle axle and rotating shaft space (being a bit larger tham bristle shaft neck width) is arranged, when so desire is changed bristle, pull down taper pin, bristle axle 7 and 8 all is easy to take out and install.
