Description

A kind of rotary tooth brush

The utility model relates to a kind of toothbrush, the rotary toothbrush of especially a kind of brush holder.

The method for brushing teeth of science is for to brush up and down along the teeth crevice direction, i.e. the perpendicular brush advocated of hygiene department, and perpendicular brush mode cleaning teeth is thorough, be not easy to damage gum, effective, but brush very bothersome, use existing traditional toothbrush constantly to move up and down brush holder with hand, inconvenience is also more tired.For addressing this problem, people have designed the rotary toothbrush of brush holder, as: the patent No. is 01207516 and 00265367 technology, realize the rotation of brush holder by transmission device or tumbler are set on toothbrush handles, but above-mentioned two technology exists toothbrush design more complicated, the higher shortcoming of cost of manufacture, toothbrush volume is also bigger, be not easy to use, in addition, also have some other rotation design, its function and effect are had nothing in common with each other, and cut both ways.

The purpose of this utility model is to provide a kind of simplicity of design, low, easy to use, the effective rotary tooth brush of cost.

The utility model is achieved in that a kind of rotary tooth brush, comprises brush, brush holder, and this brush holder comprises brush holder axle and brush holder cover, and the brush holder cover is enclosed within brush holder axle outside, can rotate with respect to the brush holder axle.

Use principle of the present utility model is: the people holds the brush holder cover or the brush holder axle uses thumb and forefinger roll brush arbor or brush holder cover to realize the rotation of toothbrush.This kind rotates the simplicity of design of design, and easy to make, cost is low, and is simultaneously, easy to use, effective.

Below in conjunction with accompanying drawing the utility model is done further detailed description:

Fig. 1 is first kind of embodiment schematic diagram of the utility model.

Fig. 2 is second kind of embodiment schematic diagram of the utility model.

Fig. 3 is the third embodiment schematic diagram of the utility model.

Fig. 4 is the 4th kind of embodiment schematic diagram of the utility model.

As shown in Figure 1, brush holder axle 1 and brush 3 are made as one, and brush holder axle 1 is a multidiameter, and be thick near the part of brush 3, be inserted in the parts of fine in the brush holder cover 2, the tail end of brush holder axle 1 connects positioner, and the illustrated position device is a nut 8, also can be other version during practical application, as draw-in groove card structure etc., brush holder axle 1 tail end machining screw, nut 8 is screwed on the brush holder axle 1, and brush holder overlaps 2 axial location between the ladder shaft shoulder and nut 8 of brush holder axle 1.
