Specific embodiment

Embodiment one

As shown in Figure 1-3, there is the ultrasonic electric toothbrush of multiple shock mitigation system described in the utility model embodiment one, The technical solution implemented purpose to be achieved is, solves during using ultrasonic motor electric toothbrush, because of ultrasound Wave motor generates obvious vibratory sensation and is transmitted to the hand of user by toothbrush handle position, and caused influence makes The usage comfort problem of user, thus, the unfavorable factor that current ultrasonic electric toothbrush is affected is for use The shockproof properties of person's hand are poor, either use conventional motors device or novel driving device, motor both ends all can be to casing Inside conduction vibration.For the electric toothbrush of different shape, different model, internal component is different, for example, inside casing 1 Fuselage support 9 assembles pcb board 8, power supply unit 10, and 1 end of casing configures tail-hood 11,1 surface switches position of casing configuration switch Decorative panel 7 etc., therefore, these belong to the conventional arrangement of electric toothbrush motor.

Technical solution used by the utility model includes at least casing 1, ultrasonic motor 4 and fuselage support 9, for Its mutual cooperation is analyzed:

Due to using ultrasonic motor 4 that the head toothbrushes outside casing 1 is driven to be swung inside casing 1, thus, meanwhile, Ultrasonic motor 4 is fixed on inside casing 1 further through fuselage support 9, it can be seen that, the either driving end of ultrasonic motor 4 Or fixing end, all can be to a certain extent by vibration conduction to 1 handle part of casing, and technical solutions of the utility model use phase Three vibration absorption units answered combine to form shock mitigation system to solve the problems, such as present on, are embodied are as follows:

Firstly, waterproof shock-absorbing silica gel sheath 2 is set inside the casing 1 for 4 central spindle of the ultrasonic motor driving end side implemented, Meanwhile ultrasonic motor 4 drives end to have end cap 3, in positional relationship, the waterproof shock-absorbing silica gel sheath 2 implemented is in end cap 3 Outside is anchored on inside casing 1 so that the waterproof shock-absorbing silica gel sheath 2 connection end cap 3 be made to be extruded together；The waterproof implemented subtracts Silica gel sheath 2 is shaken also as the damping interval together between 4 central spindle section of ultrasonic motor driving end and 1 corresponding site of casing, this subtracts Shake interval can be used as the first vibration absorption unit of technical solutions of the utility model.

Then, the ultrasonic motor 4 implemented connect with fuselage support 9 one end casing 1 inside be arranged annular silica gel Fixing sleeve 6, the silica gel fixing sleeve 6 fastening are wrapped in one end that ultrasonic motor 4 connects with fuselage support 9, the silica gel implemented Also as the damping interval together between the fixing end and fuselage support 9 of ultrasonic motor 4, which can make fixing sleeve 6 For the second vibration absorption unit of technical solutions of the utility model.

Finally, the fixing end that the ultrasonic motor 4 implemented connects with fuselage support 9 and the silica gel fixing sleeve 6 implemented Between add a damping spring 5 being made of several metallic threadlike rings, make to be formed between ultrasonic motor 4 and damping spring 5 floating Dynamic suspended state can be used as the third vibration absorption unit of technical solutions of the utility model；

Further, the damping spring 5 implemented can make damping spring 5 to super since the contact area of wire form springs is small The pressure effect that sound wave motor 4 generates is located at waterproof shock-absorbing silica gel sheath 2 set by the driving of ultrasonic motor 4 end for offsetting Elasticity counter power, be conducive to further decrease fuselage support 9 and conduct the amplitude of oscillation and shake to 1 handle part of casing.

The ultrasonic motor 4 of arrangement above is further implemented with the cooperation of corresponding vibration absorption unit:

Several lug bosses 41 are set on the outside of 4 fixing end of ultrasonic motor implemented, and make these lug bosses 41 and silicon The inner wall of glue fixing sleeve 6 is in contact, meanwhile, 4 fixing end of ultrasonic motor also has the connecting pin for holding out against damping spring 5 Face 42.

With the ultrasonic electric toothbrush of multiple shock mitigation system, used silica gel described in the utility model embodiment one Dampening assembly is using the characteristic of silica gel softness come damping vibration, for example, end cap 3 is directly squeezed with waterproof shock-absorbing silica gel sheath 2 It is pressed on the side in motor driving end inside casing 1, silica gel fixing sleeve 6 is then squeezed in the bracket side inside casing 1, because This, is squeezed by strength using soft silica gel sheath and loses soft elastic reaction, be conducive to directly promote damping effect.
