In order to make the purpose of the utility model, technical solutions and advantages more clearly understood, below in conjunction with attached drawing and implementation Example, the present invention will be further described in detail.

Fig. 1 and Fig. 2 are please referred to, the utility model provides a kind of electric toothbrush, including head toothbrushes 200 and handle 100.

The handle 100 includes the shell with accommodating cavity, the bracket 90 in the accommodating cavity, connection 31 in described The bolster 30 of bracket 90, connection 31 in the bolster 30 and connect 31 driving mechanisms in the head toothbrushes 200, connection 31 In the control panel 70 of the driving mechanism and electrical connection 31 in the power elements 60 of the control panel 70, the shell, which offers, to be passed through It wears to 31 hole of connection of the accommodating cavity, the driving mechanism includes that can generate the force piece 11 of vibration and for conducting The output shaft 12 for stating the vibrational energy of force piece 11 and passing through 31 holes of the connection and being connected with the head toothbrushes 200, it is described slow Stamping 30 offers clamping groove 301, and the force piece 11 is connected in the bolster 30 and is located in the clamping groove 301, institute Stating bolster 30 is bolster 30 made of elastic material.The elastic material is preferably rubber or flexible glue.The force piece 11 Including eccentric turbin generator and rotation connection 31 in the motor set of the shaft of the eccentric turbin generator, the connection of output shaft 12 31 In the motor set.

The utility model by bolster 30 made of elastic material be set to the driving component 10 and the bracket 90 it Between, weaken the obstruction that the force piece 11 is subject in vibration processes, reduce the influence to 11 oscillation intensity of force piece, Compared to the rigid connection 31 of driving assembly 10 and bracket 90, the vibration that 31 modes of this connection increase driving assembly 10 is strong Degree, and then enhance the oscillation intensity of the head toothbrushes 200.

On the other hand, since driving assembly 10 is generally unified specification, and the shell of handle 100 is to adapt to consumer to need Ask often be arranged it is not of uniform size, and the utility model can on the basis of not changing 10 size of the driving component only needs The lower bolster 30 of replacement cost is just able to achieve the connection 31 of driving assembly 10 Yu bracket 90, and bolster 30 is easy to get due to raw material Easy to process can according to need is processed into suitable size, reduces difficulty of processing, improves processing efficiency, improves the drive The applicability of dynamic component 10.

Referring to Fig. 1, specifically, the bolster 30 successively includes to 11 direction of force piece along the output shaft 12 Offer the counterweight section 32 of 31 sections of the connection and solid setting of the clamping groove 301.The counterweight section 32 is due to being set as real Core structure event weight is larger, increases the counterweight of handle 100, improves absorption of the handle 100 to 10 energy of driving assembly, play Effect to 100 damping of handle.

Referring to Fig. 2, preferably, the cell wall of the clamping groove 301, which offers, is through to the bolster 30 towards described The blocked hole 302 of the end face of 200 one end of head toothbrushes.The blocked hole 302 makes the clamping groove 301 have bigger deformation empty Between, the requirement to force piece 11 or 30 machining accuracy of bolster or installation accuracy is reduced, production cost is reduced, is realized fast Speed installation.

Fig. 1 and Fig. 2 are please referred to, further, the driving mechanism further includes fixed structure 20, and the fixed structure 20 wraps It includes the fixing seat 21 with mounting groove and the fixation lid 22 of the opening of the mounting groove can be covered on, the fixed lid 22 The mounting hole through setting is offered, the force piece 11 is located in the mounting groove, and the output shaft 12 passes through the installation Hole is worn to outside, and the path length of the force piece 11 is greater than the aperture of the mounting hole.The fixed lid 22 described in this way is covered on described After fixing seat 21, the force piece 11 is without departing from the mounting groove out.The fixed structure 20 can be raw convenient for unified specification Connection 31 between the force piece 11 of production and external other structures.

Referring to Fig. 1, preferably, the force piece 11 is connected in the cell wall at the mounting hole and with the mounting groove It does not contact.I.e. in installation situations, the force piece 11 is not contacted with the cell wall of the mounting groove.Preferably, the output shaft 12 outer wall fits in the hole wall of the mounting hole, with the position of the fixation force piece 11.

The utility model by the force piece 11 is connected at the mounting hole and with the cell wall of the mounting groove not Contact so that force piece 11 in vibration processes not by the constraint of other structures, avoid unnecessary energy consumption, thus will Vibration is more transferred to the output shaft 12, increases oscillation intensity.

Preferably, the fixed lid 22 is clamped with the fixing seat 21, drops out the mounting groove to prevent the force piece 11.

Referring to Fig. 2, preferably, the bolster 30 and the fixing seat 21 are sliding, in order to assemble.

Referring to Fig. 2, specifically, the bolster 30 has the cunning being arranged in the same direction with the extending direction of the output shaft 12 Road 303, the outer wall of the fixing seat 21 are equipped with the sliding rail 211 being adapted to the slideway 303.The sliding rail 211 is provided projectingly, institute Stating slideway 303 is the groove being adapted to the sliding rail 211, and the fixing seat 21 need to be only pushed by when installation along the slideway 303 The bolster 30, fast and easy positioning and installation.Preferably, the sliding rail 211 is set as opposite facing two.

Fig. 1 and Fig. 2 are please referred to, further, the electric toothbrush further includes being socketed on the output shaft 12 and being arranged in The waterproof seal 50 in 31 holes of the connection, the inner wall of the waterproof seal 50 fits in the output shaft 12 and its outer wall pastes Together in the hole wall in 31 holes of the connection.Preferably, the waterproof seal 50 is rubber parts, passes through the output shaft with waterproof body Gap between 12 and the hole wall in 31 holes of the connection is penetrated into the accommodating cavity, and 11 short circuit of force piece is avoided.

Fig. 1 and Fig. 2 are please referred to, further, the driving mechanism further includes connection 31 in the fixed lid 22 and is socketed In the reinforcing member 40 of the output shaft 12, the inner wall of the reinforcing member 40 fits in the output shaft 12 and its outer wall fits in institute The inner wall of waterproof seal 50 is stated, the reinforcing member 40 has the through hole 401 through setting and with the perforation of 31 holes of the connection. The through hole 401 plays guiding role, prevents 11 skew of the force piece being vacantly arranged from touching the mounting groove 2 Cell wall leads to the consumption of energy.The reinforcing member 40 can also play reinforcement effect to the output shaft 12, prevent the output Axis 12 is lost due to the enhancing of oscillation intensity.

Fig. 1 and Fig. 2 are please referred to, specifically, the waterproof seal 50 including being wrapped in the outer of 40 upper end of reinforcing member outside Packet portion 51 and connection 31 in the outsourcing portion 51 and offer the sealing 52 through the through-hole 501 being arranged, the output shaft 12 outer wall fits in the hole wall of the through-hole 501.

Fig. 1 and Fig. 2 are please referred to, further, the electric toothbrush further includes the counterweight positioned at 60 lower section of power elements Iron 80 for increasing the feel of the handle 100, and further weakens hand-held vibration sense.

The above is only the preferred embodiment of the utility model only, is not intended to limit the utility model, all at this Made any modifications, equivalent replacements, and improvements etc., should be included in the utility model within the spirit and principle of utility model Protection scope within.
