Abstract
The utility model relates to an electrical toothbrush, which comprises a shell and two paralleled brush holders, wherein the shell is internally provided with a DC (direct current) power supply and an electric motor; the brush holders are connected with the electric motor through a driving device, the driving device comprises two paralleled rotating shafts and a reduction gear set, wherein the paralleled rotating shafts can be rotatablely penetrated at a front end opening of the shell, the reduction gear set is formed by multi groups of meshing gears, two brush holders are sleeved at the front ends of corresponding rotating shafts; a first gear shaft of the reduction gear set is positioned at the same axis of an output shaft of the electric motor and is fixedly connected with the output shaft of the electric motor, the gear shafts of two meshing gears at the rear end of the reduction gear set are sleeved on corresponding rotating shafts, and the brush holders are driven to rotate synchronously and inversely; and the side surfaces of the brush holders are extended with bristles, the bristles and the brush holders are integrated, and the bristles are in taper structures with taper pointed rear ends. Since the bristles and the brush holders are integrated, the operation of additionally planting the bristles into brush grooves is not needed, the manufacturing steps are reduced, and the manufacturing cost is lowered; and since the bristles are in taper structures with taper pointed rear ends, the size at the head part is small, the electrical toothbrush is easy to put into the mouth, and the use is convenient.
Description
(1) technical field
This utility model relates to daily living article, particularly a kind of electric toothbrush with two brushes.
(2) 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 the effect of massage gingiva is arranged, thereby reduces paathogenic factor in the oral environment, strengthen the resistance against diseases of tissue, certain effect is all arranged for prevention of periodontal disease.Adopt correct method for brushing teeth and select one, just seem particularly important toothbrush reasonable in design.Existing conventional two head toothbrush, bristle are to implant in the brush holder complex process, cost of manufacture height; Bristle is equally big end to end cylindrical structure, causes head to follow the afterbody volume equally big, is difficult for putting into face, the inconvenience of brushing teeth; In addition, the bristle of this structure is easily sheltered evil people and countenance evil practices, and is unhygienic, uses dangerous.
(3) summary of the invention
In order to solve the shortcoming that existing electric toothbrush exists, this utility model provides a kind of electric toothbrush, adopts bristle and the integrated structure of brush holder, and processing technology is simple, cost is low, and, easy to use, health.
For this reason, this utility model is taked following technical scheme:
A kind of electric toothbrush, include housing, two parallel brush holders arranged side by side, be provided with dc source, motor in the described housing, brush holder is connected with motor by actuating device, described actuating device comprises two parallel shafts that are rotated through on the housing front port, the train of reduction gears of organizing the meshing gear composition more, and two brush holders are socketed in corresponding rotating shaft front end; First gear shaft of train of reduction gears is positioned on the same axis and with motor output shaft with the output shaft of motor fixedlys connected, the gear bush of two meshing gears of least significant end is contained in the corresponding rotating shaft, drive the rotation of two brush holder synchronous backwards, described brush holder side is extended with bristle, described bristle is made up of the bristle unit, described bristle unit is at least two, and described bristle and brush holder are one-body molded, and described bristle is to the gradually sharp pyramidal structure of its end.
Described brush holder can be socketed in the rotating shaft with changeing, and the rotating shaft that cooperates with the brush holder endoporus is provided with spline.
Described bristle is made up of four bristle unit, and the parallel brush holder direction in described bristle unit is arranged, and is arranged symmetrically in the brush holder side.
Described bristle is made up of three bristle unit, and the parallel brush holder direction in described bristle unit is arranged, and is arranged symmetrically in the brush holder side.
Described housing side is embedded with on and off switch.
Described dc source is a battery.
Employing the utlity model has following advantage: 1, bristle and brush holder are one-body molded, need not in addition bristle to be implanted in the brush holder groove, have reduced making step, have reduced cost of manufacture; 2, bristle is that the shared volume of bristle and brush holder is little, puts into face easily, and is easy to use, and the gradually sharp structure of this taper can fully guarantee the contact surface of bristle and tooth to its end pyramidal structure of point gradually, and the while can brush teeth space again; 3, the bristle of pyramidal structure is difficult for sheltering evil people and countenance evil practices, and uses health, safety; 4, brush holder is detachable is installed in the rotating shaft, and brush holder damages the back only needs the replacing brush holder to get final product, and housing and rotating shaft etc. are reusable, have avoided the wasting of resources, have reduced use cost; 5, bristle can adopt many group structural configuration in the brush holder side, can satisfy different customer demands, and is applied widely; 6, two brush holder reverse rotations, brushing molar tooth is down to brush from root of the tooth, brush lower wall tooth is up to brush from root of the tooth, reaches brushing teeth of science.
