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 1, the setting shell as handle The motor of the driving head toothbrushes and the electricity being electrically connected with the motor in the head toothbrushes of 1 front end of body, the setting shell 1 The oral area of pond, the motor front end and shell connects, and the oral area of the shell is equipped with sealing element, the drive shaft and tooth of the motor Brush head connection, the battery are rack-mount, it is characterised in that: the motor front end is connected by spring and the bracket front end It connects, and when at least described head toothbrushes are upwarded pressure, the motor is using its front end and the junction of shell as supporting point energy To lower swing.

The electric toothbrush, it is characterised in that: the motor rear end is equipped with spring mounting seat, on the spring mounting seat The first buckle circumferentially arranged equipped with one group, the bracket front end are equipped with one group of second buckle circumferentially arranged, the bullet Spring both ends pass through the first buckle respectively, the second buckle is fixed.

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, then control the operation of electric toothbrush by control device.

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 motor rear end is equipped with the triggering for triggering the control device Bar.

The electric toothbrush, it is characterised in that: the spring mounting groove of the central point and bracket of the oral area of the shell Central point is mounted obliquely on the motor in shell not in same level.

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 advantage of the utility model is as follows: motor rear end spring support is flexible coupling, when head toothbrushes by When upwarding pressure, according to lever principle, motor can be to lower swing, to rise as supporting point using its front end and the junction of shell To the effect of buffering, make destruction of the brush head to dental enamel and gum to mitigate, when pressure reaches certain value, motor rear end touching The switch of hair below closes power supply by the switch, leaves the motor off operation, or by switch triggering control chip, then by Control chip makes corresponding prompt, change movement, and when pressure is released, toothbrush restores normal operating conditions.

Specific embodiment

If Fig. 1-6 shows, 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 with the motor 3, and 3 front end of motor is connect with the oral area 10 of shell 1, the shell The oral area 10 of body 1 is equipped with sealing element 11, and the drive shaft 5 of the motor 3 is connect with head toothbrushes 2, and the battery 4 is mounted on bracket 7 On, 3 rear end of motor is connect by spring 8 with 7 front end of bracket, due to being soft company between motor rear end spring support It connects, when the head toothbrushes 2 are upwarded pressure, the motor 3 can be to as supporting point using the junction of its front end and shell 1 Lower swing.

Further, it to make both ends of the spring connection stronger, prevents from falling off, 3 rear end of motor is installed equipped with spring Seat 6, the spring mounting seat 6 are equipped with one group of first buckle 9 circumferentially arranged, and 7 front end of bracket is equipped with one group in circle Second buckle 12 of week arrangement, it is fixed that 8 both ends of spring pass through the first buckle 9, second buckle 12 respectively.The spring installation The shell of seat and motor can be integrally formed, and seperated can also be connected.

Further, it is provided with control device 14 below the motor 3, control is triggered by the swing of the motor 3 Device 14, then the operation by the control electric toothbrush of control device 14.The control device 14 be pressure switch, travel switch, Microswitch, inductive switch, the metal clips with contact or Hall element etc..Power supply is closed by the switch or device, Operation is left the motor off, or chip is controlled by switch triggering, then corresponding prompt is made (as reminded user by control chip Toothbrush is not pressed firmly) or change movement (as reduced vibration frequency).

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 spring mounting seat.The sensitivity of triggering is improved by frizzen,

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, the central point of the spring mounting groove 17 of the central point and bracket 7 of the oral area 10 of the shell 1 is not same On one horizontal plane, it is mounted obliquely on the motor 3 in shell 1.It, can also be in shell to make motor smoothly be packed into shell Muscle is led in installation.Since head toothbrushes and motor are horizontal connection, when motor is obliquely installed, also natural shape between head toothbrushes and shell At certain downward angle, more meet ergonomics, to improve the comfortableness and security brushed teeth.

The above is only the preferred embodiment of the present invention, is not intended to limit the utility model, all practical at this Made any modifications, equivalent replacements, and improvements etc., is all contained in the protection of the utility model within novel spirit and principle Within the scope of.
