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: since head toothbrushes are high-speed motion, once misoperation (is such as pressed Press through weight), dental enamel and gum can be injured, is not especially that very healthy crowd's injury is bigger to old man, children and tooth.

Utility model content

The technical problem to be solved by the present invention is to provide a kind of electric tooths that can prevent dental enamel and gum wounds Brush.

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 motor front end is flexibly connected by connecting shaft with the mounting hole on bracket with the connection of the oral area of shell, rear end, the motor Drive shaft connect with head toothbrushes, spring is set between the motor and bracket, and the oral area of the shell is equipped with sealing element, special Sign is: the mounting hole of the bracket is equipped with the gap swung for connecting shaft, and at least described head toothbrushes are upwarded pressure When, the motor can be to lower swing as supporting point using its front end and the junction of shell；

It is provided with control device below the motor, by the swing of the motor come trigger control device, then passes through control The operation of device control electric toothbrush processed.

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

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 the branch swung Point.

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 spring is tower spring.

The electric toothbrush advantage of the utility model is as follows: the space swung for connecting shaft is equipped on the mounting groove of bracket, Motor using the junction of the boss of front end and cone tank as fulcrum, when head toothbrushes upward pressure it is larger when, according to lever Principle, motor, to play the effect of buffering, can make destruction of the brush head to dental enamel and gum to lower swing to mitigate, when When pressure reaches certain value, the switch of motor rear end triggering below closes power supply by the switch, leaves the motor off operation, Or chip is controlled by switch triggering, then corresponding prompt, change movement, when pressure is released, toothbrush are made by control chip Restore normal operating conditions.

Detailed description of the invention

Utility model will be further described in detail below with reference to the attached drawings and specific embodiments.

Fig. 1 is the cross-sectional view of the utility model electric toothbrush；

Fig. 2 is the partial enlarged view of Fig. 1；

Fig. 3 is the utility model electric toothbrush internal structure exploded view；

Fig. 4 is the partial sectional view of the utility model electric toothbrush shell.

Specific embodiment

Show picture 1-4, the electric toothbrush of the utility model, including the shell 1, head toothbrushes 2, motor 3, battery as handle 4, the head toothbrushes 2 are arranged in 1 front end of shell, and the motor 3 is arranged in the shell 1 for driving the head toothbrushes 2, described Battery 4 is arranged in shell 1, and is electrically connected by pcb board 17 with the motor 3, the oral area 10 of 3 front end of motor and shell 1 Connection, 3 rear end of motor is flexibly connected and (is threaded through in mounting hole) with the mounting hole 9 on bracket 7 by connecting shaft 6, described 6 front end of connecting shaft sets flexible hook, and the other positions of the motor 3 are suspended on 1 inner cavity of shell.The drive shaft 5 of the motor 3 It is connect with head toothbrushes 2, spring 8 is set between the motor 3 and bracket 7, the oral area 10 of the shell 1 is equipped with sealing element 11.Institute The mounting hole 9 for stating bracket 7 is equipped with the gap swung for connecting shaft 6, and the waist hole of strip can be set in the mounting hole 9.Institute When stating head toothbrushes 2 and being upwarded pressure, the motor 3 using its front end and the junction of the oral area 10 of shell 1 as supporting point to Lower swing.It is provided with control device 14 below the motor 3, by the swing of the motor 3 come trigger control device 14, is passed through The operation of the control electric toothbrush of control device 14.The control device 14 is pressure switch, travel switch, microswitch, induction Switch, the metal clips with contact or Hall element etc..Power supply is closed by the switch or device, leaves the motor off fortune Row, or chip is controlled by switch triggering, then corresponding prompt is made (as reminded user not press firmly by control chip Toothbrush) or change movement (as reduced vibration frequency).

Further, 10 rear of oral area of the shell 1 is equipped with cone tank 10a, and 3 front end of motor is equipped with and the taper Slot 10a adaptable boss 13, after installing, is withstood cone tank by the boss of the active force of rear end spring, the motor front end, The motor 3 is using the junction of the boss 13 of front end and cone tank 10a as the fulcrum swung.Pass through cone tank and boss Design makes motor have enough spaces to swing, while during the swing, not will cause the deformation of sealing element, enabling sealing element There is good sealing effect.The boss and the shell of motor be integrally formed or seperated design.

Further, 3 rear end of motor is equipped with the frizzen 16 for triggering the control device 14, the frizzen It can be integrally formed with the connecting shaft.The sensitivity of triggering is improved by frizzen,
