Abstract

The utility model relates to a double-head electric toothbrush, which comprises an embedded DC power supply, a small-motor casing and two paralleled brush handle, wherein the front ends of the two brush handles are respectively provided with brush hairs; the brush handle is connected with the small motor through a transmission device. The toothbrush is characterized in that the transmission device comprises a two paralleled rational shaft that can rotationally arranged on the front end opening of the casing as well as a meshed transmission gear jacketed on the rotational shaft; the two brush handles are detachably jacketed on the front ends of corresponding rotational shafts; the rotational shaft is on the same axis with the output shaft of the small motor and is fixed and connected with the output shaft of the small motor; and the small motor drives the two brush handle to rotate inversely through a rotational shaft and a gear. The brush handle with the brush hair is jacketed onto the rotational shaft. After the brush hair is broken, only the brush handle with brush hair is needed to be replaced while the casing and the rotational shaft can be used repeatedly, avoiding waste of resource. The small motor and the rotational shaft are fixedly connection. The rotational shaft uses the meshed gear to drive another rotational shaft of rotate inversely. The structure is simple and the installation and maintenance are convenient.

Description

Two brush electric toothbrushes

Technical field

This utility model relates to daily living article, particularly a kind of electric toothbrush with two brushes.

Background technology

Brush teeth is to keep the most direct effective method of oral cavity cleaning, it can eliminate soft white dirt, food fragment and part bacterial plaque of tooth surface in the oral cavity, and massage gingiva effect arranged, thereby paathogenic factor in the minimizing oral environment, strengthen the resistance against diseases of tissue, certain effect is all arranged for prevention dental caries and periodontal disease.Adopt correct method for brushing teeth and select one, just seem particularly important toothbrush reasonable in design.Correct method for brushing teeth is perpendicular brush method, bristle is brushed downwards along diastema when brushing tooth, from lower to upper along the diastema brush, could remove residue, dental plaque and soft dirt in the interval of tooth so effectively during the brush lower tooth, can also massage gingiva, safeguard the normal of gingival contour.But when using traditional manual toothbrush to brush teeth for people with disability, child even sound adult, common employing cross-brushing method is brushed teeth, the horizontal back and forth tooth of brushing teeth, this method be to not only reaching ideal cleaning effect, also can damage tooth, gingiva, can cause the gingiva beach wormwood to contract wedge shaped defect etc.Obviously, traditional manual toothbrush is not suitable for the people with disability, the child uses, and also is difficult to correct get used to using the adult wrong method for brushing teeth of cross-brushing method.

Summary of the invention

The purpose of this utility model is to overcome the deficiencies in the prior art, and a kind of two brush electric toothbrushes simple in structure, easy to use are provided, and the tooth effect is protected in cleaning one's teeth of realizing ideal.

The purpose of this utility model is achieved through the following technical solutions:

Housing, the two parallel brush holders arranged side by side of dc source, fractional motor are established in two brush electric toothbrushes in comprising, two brush holder front ends are respectively equipped with bristle, and brush holder is connected with fractional motor by actuating device; It is characterized in that: described actuating device comprises two parallel shafts that are rotated through on the housing front port and the engaged transmission gear on the package packing rotating shaft, and two brush holders can be socketed in corresponding rotating shaft front end with changeing; Wherein a rotating shaft is positioned on the same axis and with the output shaft of fractional motor with the output shaft of fractional motor and fixedlys connected, and fractional motor is by rotating shaft, the rotation of gear driven two brush holder synchronous backwards.

Described brush holder is cylindric, sets firmly the bristle that four row are arranged vertically on the side face of its front end, becomes 90 ° between the adjacent bristle row, and the bristle row are 40 °～50 ° with the angle α of the radial centre lines of brush holder; Bristle row dislocation on two brush holders is arranged.

Described bristle row are 45 ° with the angle α of the radial centre lines of brush holder.

Be embedded with on and off switch on the side of described housing.

The utlity model has following advantage:

1, the brush holder of band bristle is socketed in the rotating shaft, after bristle damages, only needs the more brush holder of tape swapping bristle, and housing and rotating shaft are reusable, avoid the wasting of resources.

2, fractional motor is fixedlyed connected with a rotating shaft, and this rotating shaft drives another rotating shaft synchronous backward rotation by meshing gear, and is simple in structure, installation, easy to maintenance.

3, two brush holders synchronous backward rotation under the drive of fractional motor; the angle α of the radial centre lines of bristle and brush holder is 40 °～50 °; bristle with brush holder rotation is vertically scrubbed tooth along teeth space, can remove on the tooth rapidly and teeth space in residue, and can protect root of the tooth and oral cavity injury-free.
