Description

Multi-direction movement automatic tooth-brush

This utility model relates to a kind of compound motion formula automatic tooth-brush, belongs to the A61C17/16 class.

The toothbrush that people use always, get used to doing side-to-side movement along tooth with hands up and down in the oral cavity more, because usage for many years, gingiva is suffered damage, the teeth roots that has forms cut or groove owing to accumulate over a long period, and the dirt of teeth crevice is difficult to thorough removing, and therefore, the odontopathy that causes with ordinary toothbrush is of common occurrence.

The Decree of Patent Office of China " electric toothbrush " and " electric toothbrush " that CN2068086U week young tiger is designed of CN2064642U Chen Song pool design.The former can only rotate with the hairbrush of circle, the latter also can only parallel teeth meets to move back and forth up and down and brushes the tooth that rinses one's teeth with water, use above-mentioned two kinds of toothbrushes, just the side-to-side movement of manual brushes tooth ground is accustomed to, change into and move up and down, form the cut or the groove of above-below direction tooth if life-time service still can cause the gingiva damage and accumulate over a long period, more unfavorable necessary left and right directions athleticism is removed clean dirt.

The purpose of this utility model is to provide a kind of toothbrush bristle that can make to move up and down at above-mentioned deficiency, compound motion formula automatic tooth-brush that again can side-to-side movement.

The purpose of this utility model is achieved in that a kind of compound motion formula toothbrush, and it comprises that two fan head toothbrushes and being contained in by micro machine and the gear reduction unit of battery by power supply are driven on the power transmission shaft; Brush base plate cross section be two waists and top margin equate trapezoidal, the two fan bases positive hexagon shape of its section constitution of back that is harmonious, the vertical above-mentioned hexagon of bristle, its gabarit are circular arc; Brush holder is the extension of base plate, and two fans are inserted with after being harmonious in the elastic binding clasp with groove, it and the teat of the brush holder back clamping brush holder that is harmonious; Power transmission shaft the inner is equipped with hemisphere axis hole coupling and is connected in the universal coupling mode with two link rods, two link rods in addition end all are equipped with the slip roller and are limited in two radial grooves of big disk and slide, and its extension and contraction control of link rod and roller thereof is that the cam that driven by gear reduction unit and two apply pressure to stage clip on the two slip rollers.

After head toothbrushes takes out from binding clasp, two skies that can insert middle sleeve every in.

Owing to adopt such scheme, can solve the habitual move left and right brush of manual toothbrush and gargle the harm that is caused, also overcome certain this electric toothbrush simultaneously and can only move up and down bristle and brush the shortcoming of gargling; This head toothbrushes is synthetic by six bristle pack, be on the whole round, separately be again the flat pattern brush of projection slightly, thereby the brush function of gargling about having guaranteed and up and down, to dental care particularly life-time service can cleanly take out stains, can protect the tooth gingiva injury-free again; This compact conformation, small and exquisite is pulled down brush and can be put into tube, uses compact battery, is convenient to travel and carries, and can be so kind as to give gift again.

Below in conjunction with drawings and Examples this utility model is further specified.

In Fig. 1 and Fig. 3, two fan brush base plates, 101 cross sections are combined into positive hexagonal polygon mutually, totally six of bristles 102, and its gabarit is the flat pattern of arcuation projection; Two fan the binding clasp 2 of packing into after toothbrushes 1 base plate 101 is harmonious, and binding clasp 2 is made by resilient material, and utilize the teat dress jail of its internal recess, clamping brush holder 103; Binding clasp 2 is loaded on the outer end of power transmission shaft 3, power transmission shaft 3 the inners are equipped with hemisphere axis hole coupling 401 and are connected in the universal coupling mode with two link rods 4, two link rods 4 are held interior slip of two radial grooves of slip roller 402 being housed and being limited in big disk 6 in addition, link rod 4 and roller 402 its extension and contraction control thereof are after being closed by switch 15, energized (battery 16) is in micro machine 13 inputs, motor shaft mill pinlon 12 drives center gear 11 and rotates, center gear 11 and 20 quiet joining of center, center 20 is slidingly matched with middle clamp plate, the big plectane 6 of stationary fit is equipped with in its outer end, also is driven to rotate.Thereby drive head toothbrushes 1 rotation.Center 20 and center mill pinlon 7 are one, center mill pinlon 7 drove gear 10 and the coaxial quiet mill pinlon 9 of crossing of joining is rotated, thereby drive central shaft gear 8, central shaft 21 and center 20 are movingly, ellipse cam 5 is equipped with in central shaft 21 outer ends, cam 5 is by the central shaft of joining 21 driven rotary quiet with it, and cam 5 leans on mutually with slip roller 402, and roller 402 is compressed by stage clip 403.When elliptic cam 5 forwarded major axis to, the roller 402 that slides this moment was pushed to away from the center of circle, otherwise, when elliptic cam 5 forwards minor axis to, slip roller 402 is pressed to the center of circle by stage clip 403, affects power transmission shaft 3 to move along upper bush 19 centre bores thereby promote link rod 4, and drive head toothbrushes 1 moves forward and backward.

As shown in Figure 2, head toothbrushes 1 not be after the time spent can take out from binding clasp 2, can insert the about two empty in 181,182 of middle sleeve 18.
