Abstract

The utility model relates to a rotary toothbrush, comprising a hollow brush holder, a brush bristle component which is movably connected with a transmission rod in the brush holder, a finger-operating component which is arranged at the top part of the brush holder and can axially slide along the surface of the brush holder and a driving gear which is arranged in the bush holder and can drive brush bristles to back and forth turn along radial direction. The utility model with simple structure can easily rotate the brush bristles, and the brush bristle component can be changed.

Description

A kind of rotary toothbrush

The utility model relates to a kind of cleaning teeth dirt and rotatable toothbrush of bristle of being used for.

In the prior art, the toothbrush that people generally use is that bristle is fixed on the end regions of brush holder and forms one with brush holder.Use this kind toothbrush to brush teeth generally mostly to be along laterally pulling back and forth of tooth, this kind teeth brushing way is assert the destructible gums through science, and the easy-clear not of the dirt in the teeth space.As very inconvenient again along tooth above-below direction pulling with this kind toothbrush, and staff does this action and is difficult to grasp suitable dynamics, also easily makes the brush holder collision gum or the gums of fasten bristles part, makes injury of teeth.

For solving this class problem, people explore the toothbrush that bristle can radially be rotated along brush holder, and two kinds of electrodynamic type and hands are arranged at present.The rotating toothbrush of so-called electrodynamic type bristle is to drive bristle with micromotor to rotate, though it can overcome above-mentioned deficiency, its cost is higher, and volume is big, and dry sound is arranged, and the conversion of bristle rotation direction is also quite difficult, so this kind toothbrush is difficult for promoting the use of.

The so-called manual or rotating toothbrush of bristle comparatively it is desirable to " manually rotary toothbrush " that Chinese patent CN2052222U announces at present.This kind toothbrush is that the bristle head is connected with a cylindricality gear, and button and tooth bar join, and tooth bar is meshed with stud wheel, in the bottom of tooth bar return spring are installed.When pressing button downwards, make brush rotate an angle, when unclamping button, return spring promotes tooth bar and makes angle of brush opposite spin.Though this kind toothbrush is simple in structure, must limit its anglec of rotation, user's frequency key pressing of having to just can reach the purpose of cleaning teeth.In addition, excessive when its anglec of rotation, brush two ends solid is easily hindered gum.

Task of the present utility model provides a kind of manual rotary toothbrush, and it rotates hair brushing part easily by simple driving mechanism, and can not damage any position, oral cavity.

For finishing above-mentioned task, the utility model adopts the brush holder of a hollow and the hair brushing part that flexibly connects with drive link in this brush holder, with the finger dynamic component that is arranged on brush holder top, and be installed in the brush holder and can make hair brushing part radially come the driving mechanism of back rotation; This driving mechanism comprises and refers to tooth bar and the promotion that dynamic component is affixed or spurs the elastomeric element of this tooth bar return; Its end regions was meshed with a cylindricality gear when above-mentioned tooth bar was static, and cylindricality gear bottom is a bevel gear, and this bevel gear is meshed with the bevel gear of drive link end.Along the endwisely slipping or radially press the finger dynamic component of brush holder, by driving mechanism hair brushing part is radially rotated back and forth with hand, its hair brushing part velocity of rotation can be adjusted easily with pointing.

Described finger dynamic component and the tooth bar that joins with it can radially extend in the brush holder, and this tooth bar directly is meshed with the stud wheel of drive link end.

Described elastomeric element can be made of stage clip.

Described hair brushing part one end is provided with nose bar, and this nose bar can be screwed on the drive link and make hair brushing part and brush holder axial engagement and then formation one.

Because the utility model adopts the manually mode of rotation bristle, and the mechanism that drives the bristle rotation is made of the intermeshing wheel of nibbling, it can rotate bristle easily back and forth, and velocity of rotation can automatically be adjusted by finger, or is recently adjusted by the modulus of two intermeshing bevel gears.In addition, its structure is simple especially, and is sturdy and durable, once the bristle wearing and tearing also can only be changed hair brushing part, and need not the integral replacing toothbrush.

Below in conjunction with drawings and Examples the utility model is elaborated.

Accompanying drawing 1 is the generalized section of the utility model appearance structure;

Accompanying drawing 2 is generalized sections of another embodiment of the utility model.

Referring to Fig. 1, the utility model comprises hair brushing part 2 and a brush holder 1 from seeing in appearance, and they interconnect by the drive link 3 that is arranged in the brush holder 1, and demolition mutually.Hair brushing part 2 is provided with a nose bar 21, its surface is provided with external screw thread, and drive link 3 is provided with nose bar 21 joining parts and can accepts this externally threaded internal thread, like this, nose bar 21 can be screwed on the drive link 3, makes hair brushing part 2 and brush holder can form one from seeing in appearance.Certainly, hair brushing part 2 also can adopt multiple mode to flexibly connect with drive link 3, as adopting socket connection etc.

Partly also can know the structure of finding out driving mechanism from the section of Fig. 1.Even the power that this power hair brushing part 2 that drives mechanism rotates is mainly finished by finger dynamic component 4 and elastomeric element 7.Brush holder 1 is provided with microscler chute, refers to that dynamic component 4 is installed in microscler chute top, and its lower lobes partly extend in the microscler chute, and affixed with the tooth bar 5 in the brush holder 1.The end cylindricality gear 6 interior with being limited to brush holder 1 was meshed when tooth bar 5 was static, and tooth bar 5 tops and elastomeric element 7 join, and this elastomeric element can be made of stage clip, and its other end leans on brush holder 1 inwall.The bottom of columnar tooth 6 is affixed or make the disc and the flank of tooth bevel gear 8 down of one with it, and this bevel gear is meshed with the bevel gear 9 of drive link 3 ends.During use, as long as refer to dynamic component 4 along microscler chute slip with finger, make linearly operating by the fixing tooth bar 5 of its underpart, give cylindricality gear 6 with its force transmission again, rotate thereby drive two bevel gears (8,9), hair brushing part 2 also rotates thereupon, when finger unclamped finger dynamic component 4, elastomeric element 7 pushing tow tooth bars 5 made hair brushing part 2 to counter-rotation, so repeatedly repeatedly, can realize the cleaning teeth purpose.

Another embodiment of the utility model radially extend into above-mentioned finger dynamic component 4 and tooth bar 5 in the brush holder 1, and as shown in Figure 2, the top of drive link 3 is connected with stud wheel 51, and this stud wheel is meshed with

tooth bar

5, and 5 times tops of described tooth bar and stage clip 52 join.When downwards by finger dynamic component 4, can drive tooth bar 5 and stud wheel 51 actions, thereby hair brushing part 2 is rotated; Open when referring to dynamic component 4 when openhanded, stage clip 52 can pop up tooth bar 5, thereby can make stud wheel 51 and hair brushing part 2 to counter-rotation.
