Description

Teeth-shaped swing type electric toothbrush

This utility model belongs to daily life product.

Still lack ideal electric toothbrush in the market, as seen this is still had many worth researchs and improved place.Axially rotation is just done in the electric toothbrush that has simply, does not meet the brushing up and down of science.The electric toothbrush that has has then been installed planetary gear, toggle and has been realized swinging up and down of brush, but structure is too complicated, in the middle of multistage transmission in vain loss a large amount of kinetic energy, thereby need often change battery, moreover run up and make pinion wherein very easily wear and tear, service life is not long.

The purpose of this utility model provides the electric toothbrush that a kind of new profile of tooth brush is done the vertically shaking motion, and it adopts new structural design, and not only power is strong, power consumption is little, and not fragile, durable in use.

This utility model is realized in the following manner: this electric toothbrush is made up of fuselage (2) and brush body (10), eccentric (4) and swing arm (5) are installed on the micromotor in the fuselage (3) axle successively, break-in axle (6) has been installed above the swing arm medial launder, this axle and motor coaxle, thereby the Motion Transmission of motor shaft is arrived brush holder (7) position, make its reciprocally swinging in the certain angle scope, and produce certain vibration.

Tooth-brush handle has the wedge keyway to match with the break-in shaft head, and the disassembling, assembling and replacing plug is convenient.Brush (9) has adopted new tooth Shape Design, makes bristle (13) be two spills shown in the accompanying drawing 3, has preferably with tooth to contact.Also have semicircular guard shield (8) at the behind of brush body face, avoid scraping or trembleing with other positions in the protection oral cavity.

This utility model has been cancelled planetary gear owing to adopted above-mentioned new structural design, makes to simplify the structure, and power is strong during work, power consumption is little, and a common batteries can use one month, and part is not easy to wear, and prolong service life greatly.The swing type of this electric toothbrush is scrubbed and the profile of tooth bristle, with its particular structure and teeth brushing way, the dirt in Ya Biao and the teeth space thoroughly can be removed comprehensively, and can be played the effect that tooth is protected in the health care of massage gingiva.Brush body can be changed, and such machine can use not only health but also economy for many people.

Fig. 1 is the structural representation of this utility model electric toothbrush.

Fig. 2 is the vertical view of running part.

Fig. 3 is a head toothbrushes tooth Shape Design sketch map.

Embodiment 1, opens switch (12), energized (1), miniature electric arbor (3) rotates, the rotation of eccentric (4) makes swing arm (5) make reciprocally swinging back and forth, through the effect of break-in axle (6), drives the toothbrush that is installed in above it and swings up and down in the certain angle scope.Fuselage (2) has O-ring seal (11) with the binding site of brush body (10), in case the fuselage infiltration.The fuselage size just can be pinned gingiva with brush (9) during use gently for shaking hands, and slowly moves, and can brush teeth and can massage gingiva.This utility model electric toothbrush adopts battery of a joint to get final product, and needn't everyday charge, and travelling is convenient and practical at home.
