Specifically, the driving member 2 further comprises the third abutting wall 23, the third abutting wall 23 is internally provided with a coil, the third abutting wall 23 is arranged axially along the handle body 1 and is arranged spaced apart from the inner side wall of the handle body 1, the mounting seat 12 comprises the third seat body 123, the third seat body 123 is arranged at an end of the third abutting wall 23 away from the first seat body 121, and the third damping portion 313 is arranged between the third seat body 123 and the third abutting wall 23, so that the other part of the third abutting wall 23 and the inner side wall of the handle body 1 are left with a gap and are not in contact, i.e. the third seat body 123 and the third abutting wall 23 are arranged spaced apart from each other, thereby ensuring that the third abutting wall 23 of the driving member 2 and the third seat body 123 of the mounting seat 12 are not in direct contact in the radial direction of the handle body 1.

[0055] Notably, in the present embodiment, the mounting seat 12 comprises the first seat body 121, the second seat body 122 and the third seat body 123, the second seat body 122 is arranged radially along the handle body 1 and connects the first seat body 121 and the third seat body 123; the driving member 2 has the first abutting wall 21 corresponding to the first seat body 121, the second abutting wall 22 corresponding to the second seat body 122 and the third abutting wall 23 corresponding to the third seat body 123; the first damping member 31 comprises the first damping portion 311, the second damping portion 312 and the third damping portion 313, the first damping portion 311 is arranged between the first seat body 121 and the first abutting wall 21, the second damping portion 312 is arranged between the second seat body 122 and the second abutting wall 22, and the third damping portion 313 is arranged between the third seat body 123 and the third abutting wall 23, so that the driving member 2 is not in direct contact with the mounting seat 12 and the inner side wall of the handle body 1.

[0056] Preferably, the first damping part 311 and the third damping part 313 are arranged axially spaced apart around the handle body 1, so that the first seat body 121 is at least partially spaced apart from the first abutting wall 21, and the second seat body 122 is at least partially spaced apart from the second abutting wall 22. In the embodiment, the first damping part 311 is arranged axially spaced apart around the handle body 1, so that the first seat body 121 is partially in soft contact with the first abutting wall 21 through the first damping part 311, and the other part of the first seat body 121 and the other part of the first abutting wall 21 are spaced apart, at this time, the elastic coefficient of the first damping part 311 is better, the elastic performance is better, and more vibrations of the driving part 2 can be accepted. The third damping part 313 is also arranged axially spaced apart around the handle body 1. Meanwhile, the second seat body 122 is also provided with a fixing hole, and the second damping part 312 should be provided with a gap, which facilitates the fixing part to pass through the fixing hole of the second seat body 122 in the axial direction and then connect the driving part 2, so that the mounting seat 12 and the driving part 2 are fixedly installed. It is worth noting that the third seat body 123 is arranged outside the third abutting wall 23, and the third damping part 313 is arranged between the third seat body 123 and the third abutting wall 23. The third damping part 313 has a similar effect to the first damping part 311, both of which make the driving part 2 and the mounting seat 12 not directly contact in the radial direction of the driving part 2. Therefore, in the deformation embodiment, the third seat body 123 and the third damping part 313 can also be omitted, so that the third abutting wall 23 is directly spaced apart from the inner side wall of the handle body 1. Or an additional damping part is arranged on the third abutting wall 23, so that the third abutting wall 23 does not directly contact the inner side wall of the handle body 1.

[0057] Further, with reference to Figure 7 , the mounting seat 12 further comprises a fourth seat body 124, the fourth seat body 124 is arranged at one end of the first seat body 121 close to the first channel 11, and the handle body 1 is further provided with a mounting ring wall 13, and the fourth seat body 124 is adapted to abut and be mounted on the mounting ring wall 13; the damping assembly 3 further comprises a second damping part 32, the second damping part 32 is arranged between the fourth seat body 124 and the mounting ring wall 13, so that the mounting seat 12 and the mounting ring wall 13 are not directly in contact.

[0058] In the embodiment, the fourth seat body 124 is arranged at one side of the mounting seat 12 close to the first channel 11, and the fourth seat body 124 is fixedly connected with the mounting ring wall 13 inside the handle body 1, and the second damping part 32 is arranged between the fourth seat body 124 and the mounting ring wall 13, so that the mounting seat 12 and the mounting ring wall 13 are not directly in contact, and the vibration of the mounting seat 12 is not transmitted to the handle body 1.

[0059] Specifically, the second damping member 32 is arranged between the fourth seat body 124 of the mounting seat 12 and the mounting ring wall 13, so that the mounting seat 12 and the handle body 1 are also in soft contact, avoiding the transmission of vibration and noise. The mounting ring wall 13 extends along the handle body 1 away from the side of the first channel 11, and the mounting ring wall 13 is located outside the fourth seat body 124. The second damping member 32 includes a fourth damping part 321, a fifth damping part 322, and a sixth damping part 323. The fourth damping part 321 is arranged between the end of the fourth seat body 124 and the inner side wall of the handle body 1. The fifth damping part 322 is arranged between the inner side wall of the mounting ring wall 13 and the outer side wall of the fourth seat body 124. The sixth damping part 323 is arranged between the end of the mounting ring wall 13 and the first seat body 121. Preferably, a plurality of first damping protrusions 3221 are further arranged on the fifth damping part 322. The first damping protrusions 3221 are arranged along the axial direction of the handle body 1 and are arranged between the inner side wall of the mounting ring wall 13 and the outer side wall of the fourth seat body 124. The first damping protrusions 3221 improve the elastic performance of the fifth damping part 322. The inner side wall of the first seat body 121 has a relatively long axial length, so that the contact area between the inner side wall of the first seat body 121 and the drive shaft 24 is too large. This results in that the fifth damping part 322 may not be able to completely buffer the vibration of the drive shaft 24, and a part of the vibration of the drive shaft 24 still reaches the mounting seat 12 through the fifth damping part 322. Although this vibration is very subtle, it cannot be ignored. Therefore, a plurality of first damping protrusions 3221 are arranged at intervals on the outer circle of the fifth damping part 322. The outer circle of the first damping protrusions 3221 is in contact with the inner side wall of the first seat body 121, thereby reducing the contact area between the fifth damping part 322 and the inner side wall of the first seat body 121. This effectively solves the problem of excessive contact area between the fifth damping part 322 and the inner side wall of the first seat body 121. At the same time, the gaps between the plurality of first damping protrusions 3221 also provide a larger deformation space for the fifth damping part 322, thereby enhancing the elastic effect of the fifth damping part 322 and making the fifth damping part 322 have a stronger damping effect. At the same time, the first damping protrusions 3221 are in interference fit with the drive shaft 24, so that the fifth damping part 322 is in sealed connection with the drive shaft 24, thereby playing a waterproof role. The plurality of first damping protrusions 3221 play the effect of multiple waterproof barriers, thereby preventing water in the first channel 11 from reaching the drive member 2 through the gap between the mounting ring wall 13 and the fourth seat body 124, and improving the waterproof level of the toothbrush handle.

[0060] Further, the second damping member 32 further includes a seventh damping part 324. The seventh damping part 324 is arranged on the side of the sixth damping part 323 close to the central axis of the handle body 1.
