Abstract

The utility model discloses an electric toothbrush which is composed of a toothbrush handle which is provided with a motor and a battery box, a miniature motor, a brush rod fixing sleeve, a brush head lever, a movable toothbrush head and an eccentric cam, wherein the eccentric cam is driven by a gear on a main shaft of the motor to rotate, therefore the brush head lever can be driven to swing to realize the left and right swing of the toothbrush head. In addition, the goal of brushing up and down can be achieved. Three different kinds of brushing actions, an electric shearing type, a swing type and a rolling type, can be realized by the structural change of the brush head lever by the eccentric cam of the utility model and each type has unique advantages. At the same time, certain effects of massage and polish are achieved because of the slight vibration during tooth brushing. The utility model has the advantages of reasonable structure, scientific and practical design, simple use method, convenient carrying during touring, etc., and the brush head can be replaced.

Description

Electric toothbrush

The utility model discloses a kind of life appliance, specifically a kind of electric toothbrush.

At present, employed toothbrush all is that a side at brush holder has bristle in our daily life, the custom usage be about horizontal brush, this custom of brushing teeth promptly totally can not damaged gingiva again, the method for brushing teeth of science is along the upper and lower perpendicular brush of tooth, also be on the market now and some electric toothbrushes occurred, but because of its complex structure, volume is excessive, be not easy to carry, cost an arm and a leg and make vast consumer be difficult to accept, these electric toothbrush function singlenesses can only realize a kind of action of brushing teeth in addition.

The purpose of this utility model be to provide a kind of simple in structure, cheap, be easy to carry, can realize multiple brush teeth the action electric toothbrush.

The purpose of this utility model is to realize like this, this toothbrush is by the toothbrush handle that has motor and battery case, micromachine, the brush holder support fixed cover, the brush lever, active head toothbrushes, eccentric cam is formed, it is to rotate by the gear driven eccentric cam on the electric machine main shaft, thereby drive the brush lever swing and realize swinging of head toothbrushes, reach, following perpendicular brush, its motor and battery case are arranged on the inside of toothbrush handle, on toothbrush handle, have a switch, a gear is set on the main shaft of motor, eccentric cam be set at toothbrush handle on cover corresponding position, the chassis edge of eccentric cam has that teeth are used for and gears engaged, the brush lever is set in the brush holder support fixed cover, " U " shape card and eccentric cam by brush lever lower end are set together, and active brush is installed in the top of brush lever.

This utility model is owing to adopted above-mentioned structure to have the following advantages:

1, product of the present utility model is to be first defence line to various diseases according to brushing teeth of advocating of WHO, and the science of call method for brushing teeth is a standard with perpendicular brush, Anti-dental injury gum and dental bed development, this toothbrush can swing up and down along slot, can remove the foreign material and the dirt of slot depths, reach the prevention of various odontopathy.

2, the structural change of this utility model by eccentric cam brush lever can realize electronic shearing, swing type, three kinds of different actions of brushing teeth of roller, each have its unique advantage, so simultaneously owing to have slight vibration sense to play the effect of certain massage and polishing when brushing teeth.

3, this kind toothbrush is fit to people's use of various age brackets, and particularly for the child, use electrodynamic type toothbrush as a kind of toy, can increase the interest of child to brushing teeth with it, also can make the child form the good hygiene custom that love is brushed teeth.

4, this utility model is rational in infrastructure, science is practical, brush is replaceable, and using method is simple, tourism is carried also very convenient.

Concrete structure of the present utility model is provided by following examples and accompanying drawing thereof.

Fig. 1 is the electric toothbrush perspective view

Fig. 2 realizes the electric toothbrush structural representation of wobbling action for another embodiment

Fig. 3 realizes the electric toothbrush structural representation of scroll actions for another embodiment

Describe the realization situation of concrete structure of the present utility model and various function actions in detail below in conjunction with accompanying drawing: this toothbrush is by the toothbrush handle 1 that has motor and battery case, micromachine 2, brush holder support fixed cover 3, brush lever 4, active head toothbrushes 5, eccentric cam 6 is formed, it is to drive eccentric cam 6 by the gear on motor 2 main shafts 7 to rotate, thereby drive 4 swings of brush lever and realize swinging of head toothbrushes 5, reach, following perpendicular brush, its motor 2 and battery case 9 are arranged on the inside of toothbrush handle 1, on toothbrush handle 1, have a switch 8, a gear 7 is set on the main shaft of motor 2, eccentric cam 6 be set at toothbrush handle 1 on cover corresponding position, the chassis edge of eccentric cam 6 has teeth and is used for and gear 7 engagements, brush lever 4 is set in the brush holder support fixed cover 3, " U " shape card and eccentric cam 6 by brush lever 4 lower ends are set together, and active brush is installed in the top of brush lever 4.

(1), by shown in Figure 1: in order to realize shearing action, the brush lever adopts two groups, and overlapped placement, adopt two brushes, have two eccentric lobe on the eccentric cam, drive the brush lever relative motion of overlapped placement by it, thereby realized scissor function.

(2), by shown in Figure 2: the realization of swing function is by the driven by motor eccentric cam, makes head toothbrushes realize swinging by the brush lever.

(3), by shown in Figure 3: the realization of rolling function is that brush lever and brush are become one, directly link to each other with electric machine main shaft, when motor (can increase a reductor slow down) thus brush holder support rotates thereupon and realizes the function of rolling when rotating.
