Description

A kind of electric toothbrush

Technical field

The utility model relates to a kind of electric toothbrushes.

Background technique

Electric toothbrush makes that brush head quickly move or high-frequency vibration cleans tooth by the quick movement of electric core, simultaneously Toothpaste is resolved into subtle foam by vibration moment, deeply cleans teeth space, at the same time, the trembling of bristle can promote the blood in oral cavity Circulation, has massage effect to gingiva tissue.But there are problems to be: 1, due to the high-speed motion of head toothbrushes, once misoperation is (such as Press overweight), dental enamel and gum can be injured, is not especially that very healthy crowd injures more to old man, children and tooth Greatly；2, it is limited by traditional structure, most of head toothbrushes and shell are level design, do not meet ergonomics, and that brushes teeth relaxes Adaptive is poor；3, due to the circular arc spread geometry of the use habit of people and tooth, its toothbrush handle of the toothbrush of horizontal structure is easy to touch Contact tooth, since toothbrush handle hardness is very high, therefore when brushing teeth, once touching, high-frequency vibration will be damaged seriously by toothbrush handle Tooth.

Utility model content

The technical problem to be solved by the present invention is to provide one kind comfort of brushing teeth is good and can prevent dental enamel and tooth The electric toothbrush of gum injury.

To solve the above problems, the technical solution adopted in the utility model includes shell, the setting shell as handle The motor of the interior driving head toothbrushes of head toothbrushes, the setting shell of body front end and the battery being electrically connected with the motor, The connection of the oral area of the motor front end and shell, rear end are connect by connecting shaft with the mounting hole on bracket, the drive of the motor Spring is arranged in moving axis and head toothbrushes horizontal connection between the motor and bracket, the oral area of the shell is equipped with sealing element, special Sign is: the central point of the mounting hole of the central point of the oral area of the shell and the bracket makes institute not in same level Motor is stated to be mounted obliquely in shell.

The electric toothbrush, it is characterised in that: the mounting hole of the bracket is equipped with the space swung for connecting shaft, until When few head toothbrushes are upwarded pressure, the motor can be to the bottom as supporting point using its front end and the junction of shell It is dynamic.

The electric toothbrush, it is characterised in that: the oral area rear of the shell is equipped with cone tank, and the motor front end is set There is the boss being adapted with the cone tank, the motor is using the junction of the boss of front end and cone tank as fulcrum.

The electric toothbrush, it is characterised in that: be provided with control device below the motor, pass through the pendulum of the motor It moves and carrys out trigger control device, the operation of the electric toothbrush is controlled by control device.

The electric toothbrush, it is characterised in that: the motor rear end is equipped with the triggering for triggering the control device Bar.

The electric toothbrush, it is characterised in that: the housing cavity is equipped with the positioning region positioned to motor.

The electric toothbrush, it is characterised in that: the spring is tower spring.

The electric toothbrush, it is characterised in that: the control device is pressure switch, travel switch, microswitch, sense Inductive switch or Hall component.

The electric toothbrush, it is characterised in that: the positioning region is that the reinforcing rib of the housing cavity is formed.

The electric toothbrush advantage of the utility model is as follows: 1, being designed by reasonable structure, keep the motor inclined It is mounted in shell, since head toothbrushes and motor are horizontal connection, when motor is obliquely installed, between head toothbrushes and shell also certainly Certain downward angle is so formed, more meets ergonomics, to improve the comfortableness and security brushed teeth；2, in bracket Mounting groove is equipped with the space that swings for connecting shaft, motor using the junction of the boss of front end and cone tank as fulcrum, when When head toothbrushes upward pressure larger, according to lever principle, motor can be to lower swing, so that the effect of buffering is played, to mitigate Make destruction of the brush head to dental enamel and gum, when pressure reaches certain value, the switch of motor rear end triggering below passes through The switch closes power supply, leaves the motor off operation, or control chip by switch triggering, then made by control chip and being mentioned accordingly Show, change movement, when pressure is released, toothbrush restores normal operating conditions.
