Abstract

The utility model discloses a non-electrical rotating tooth brush, comprising a brush head (1) and a brush handle, wherein the brush handle comprises two segments rotating relative to each other, one segment is provided with a multi-diameter shaft, while the other segment has a shaft hole (6) engaged with the multi-diameter shaft, the multi-diameter shaft comprises a rotating portion (3), a transition portion (4) and a securing block (5), a securing groove (7) is arranged inside the shaft hole (6) corresponding to the securing block (5), and the diameter of the entrance of the securing groove (7) is smaller than the external diameter of the securing block (5). The utility model has the advantages of the simple structure, the suitability for technique production and the low production cost.

Description

A kind of non-electric rotary tooth brush

Technical field

The utility model relates to a kind of rotary tooth brush, particularly a kind of non-electric rotary tooth brush.

Background technology

The rotary tooth brush of prior art has electronic and manual two kinds, electric structure is easy-to-use, but volume is big, the cost of manufacture height, improper use also damages gum easily, manually structure mainly is to utilize brush holder to rotate, brush holder is divided into relatively turnable two sections, the people holds the brush holder hypomere and rotates the rotation that the brush holder epimere is realized brush with thumb and forefinger during use, this kind design toothbrush volume is little, making and use cost are low, simultaneously can conveniently adopt the upright brush mode of brushing up and down along the teeth space direction, cleaning teeth is thorough, is not easy to damage gum, the applicant successively applied for two of the patents (patent No. is respectively 01275337.8 and 03217109.9) of technique scheme, but the concrete technical scheme that in patent, proposes, very unsuitable explained hereafter and market demands, cost of manufacture is also than higher.

Summary of the invention

The non-electric rotary tooth brush that the purpose of this utility model is to provide a kind of more reasonable structure, manufactures more convenient practicality, cost is low.

The utility model is achieved in that a kind of non-electric rotary tooth brush, comprise brush and brush holder, brush holder by can be in relative rotation two sections constitute, one section of this brush holder is provided with the step axle, the axis hole that another section setting matches with the step axle, the step axle comprises rotation section, transition part and Ka Tai, is provided with in the axis hole and the corresponding draw-in groove of card platform, and draw-in groove porch internal diameter is less than card platform external diameter.

The utility model has the advantages that structure is advantages of simple more, suitable explained hereafter, cost of manufacture is low.

Fig. 1 cuts open figure for the office of first kind of embodiment of the utility model.

Fig. 2 cuts open figure for the office of second kind of embodiment of the utility model.

Fig. 3 cuts open figure for the office of the third embodiment of the utility model.

The specific embodiment

As shown in Figure 1, brush holder is divided into two sections, one section is connected as a single entity with brush 1, and the step axle is set, the axis hole 6 that another section setting matches with the step axle, step axle component of rotation portion 3, transition part 4 and Ka Tai 5 at the rear portion, the diameter of card platform 5 is greater than transition part 4 diameters, less than rotation section 3 diameters, the end of axis hole 6 is a draw-in groove 7, and draw-in groove 7 internal diameters are slightly less than card platform 5 external diameters.During use, the step axle is inserted in the axis hole 6, exert oneself slightly, make card platform 5 parts snap in draw-in groove 7 location.So, can make brush holder relatively rotate and not throw off for two sections, guarantee result of use.

Rotational structure simplicity of design of the present utility model, easy to make, scheme compared to existing technology, mass production preferably.

Make for the technology that further facilitates axis hole 6 structures, axis hole 6 rear sides can be designed to the rounding off structure near the part of draw-in groove 7, and draw-in groove 7 parts can be processed as opening form, draw-in groove 7 is open-minded in the upper end or the lower end of brush holder, as shown in Figure 2, perhaps two ends are open-minded up and down, as shown in Figure 3.

For conveniently holding, the epimere design of brush holder has skid resistant course 2.

Claims

1, a kind of non-electric rotary tooth brush, comprise brush (1) and brush holder, brush holder by can be in relative rotation two sections constitute, it is characterized in that: one section of this brush holder is provided with the step axle, the axis hole (6) that another section setting matches with the step axle, the step axle comprises rotation section (3), transition part (4) He Katai (5), and the draw-in groove (7) corresponding with Ka Tai (5) is set in the axis hole (6), and draw-in groove (7) porch internal diameter is less than Ka Tai (5) external diameter.

2, non-electric rotary tooth brush according to claim 1 is characterized in that: this draw-in groove (7) is the groove structure, and draw-in groove (7) is open-minded at the upper and lower or above-below direction of brush holder.
