[0002] Electric toothbrushes are popular among consumers due to their ease of use and superior cleaning effect. An electric toothbrush consists of a brush head and a handle. The handle typically houses a motor and power supply. When powered on, the motor drives the brush head to operate, thus achieving the effect of cleaning the oral cavity.

[0003] However, the operation of a motor will inevitably produce vibration. The motor in existing electric toothbrushes is usually just tightly fixed to the core bracket inside the handle, lacking a shock-absorbing structure. Therefore, the vibration of the motor will be directly transmitted to the outer shell through the core bracket, which will affect the user's experience. Utility Model Content

[0004] In view of this, the purpose of this application is to overcome the shortcomings of the prior art and provide an electric toothbrush handle to solve the technical problem that the vibration of the motor is directly transmitted to the outer shell through the core bracket, which affects the user's experience.

[0024] like Figure 1 , Figure 2 and Figure 4 As shown, an embodiment of this application provides an electric toothbrush handle 100, which is mainly used in an electric toothbrush 1000. The electric toothbrush handle 100 includes a housing 110, a motor support 120, and a shock-absorbing component 130.

[0025] The housing 110 has a receiving cavity 112 with an opening 111 at one end, and the movement support 120 is disposed in the receiving cavity 112. The buffer and shock absorber 130 is sleeved on the outer periphery of the movement support 120 and abuts against the outer periphery wall of the movement support 120 and the cavity wall of the receiving cavity 112, respectively.

[0026] The electric toothbrush handle 100 provided in the embodiments of this application has a housing 110 with a receiving cavity 112 having an opening 111 at one end. The core support 120 is disposed in the receiving cavity 112. By sleeved on the outer periphery of the core support 120, a buffer and shock absorber 130 is respectively fitted to abut against the outer periphery wall of the core support 120 and the cavity wall of the receiving cavity 112. Under the buffer and shock absorption effect of the buffer and shock absorber 130, the vibration transmitted from the drive motor to the housing 110 through the core support 120 is absorbed, thereby reducing the vibration felt by the housing 110 on the user's hand when using the device, and thus effectively improving the user experience.

[0027] For example, the shock absorber 130 can be made of silicone or rubber.

[0028] like Figure 2 and Figure 3 As shown, in one embodiment of this application, an annular mounting groove 121 is provided on the outer peripheral wall of the mechanism support 120, and the buffer and shock absorber 130 is disposed in the annular mounting groove 121.

[0029] In this embodiment, by opening an annular mounting groove 121 on the outer peripheral wall of the movement support 120 and placing the buffer damping member 130 on the annular mounting groove 121, the side wall of the annular mounting groove 121 can be used to axially limit the buffer damping member 130, effectively preventing the buffer damping member 130 from moving away from the movement support 120 along the axial direction of the movement support 120 and causing the buffer damping function to fail.

[0030] like Figure 2 and Figure 3 As shown in the above embodiments of this application, the bottom wall of the annular mounting groove 121 is provided with a limiting protrusion 1211, and the inner circumferential wall of the buffer damping member 130 is provided with a limiting groove 131 that cooperates with the limiting protrusion 1211.

[0031] In this embodiment, by providing a limiting protrusion 1211 on the bottom wall of the annular mounting groove 121 and a limiting groove 131 that cooperates with the limiting protrusion 1211 on the inner circumferential wall of the buffer damper 130, the circumferential rotation of the buffer damper 130 around the movement support 120 is restricted under the convex-concave cooperation of the limiting protrusion 1211 and the limiting groove 131. This ensures the stability and reliability of the contact between the buffer damper 130 and the outer circumferential wall of the movement support 120 and the cavity wall of the receiving cavity 112, thereby ensuring the stability and reliability of the buffer damping function.

[0032] In the above embodiments of this application, the bottom wall of the annular mounting groove 121 is provided with a limiting groove, and the inner circumferential wall of the buffer damping member 130 is provided with a limiting protrusion that cooperates with the limiting groove.

[0033] In this embodiment, by providing a limiting groove on the bottom wall of the annular mounting groove 121 and providing a limiting protrusion that cooperates with the limiting groove on the inner circumferential wall of the buffer damper 130, the circumferential rotation of the buffer damper 130 around the mechanism support 120 is restricted under the concave-convex cooperation of the limiting groove and the limiting protrusion. This ensures the stability and reliability of the contact between the buffer damper 130 and the outer circumferential wall of the mechanism support 120 and the cavity wall of the receiving cavity 112, thereby ensuring the stability and reliability of the buffer damping function.

[0034] like Figure 2 As shown, in any of the above embodiments of this application, the mechanism support 120 is provided with a first snap-fit ​​portion 122 at one end near the opening 111, and the cavity wall of the receiving cavity 112 is provided with a second snap-fit ​​portion 1121 that snaps into the first snap-fit ​​portion 122.

[0035] In this embodiment, a first locking part 122 is provided at one end of the movement bracket 120 near the opening 111, and a second locking part 1121 is provided on the cavity wall of the receiving cavity 112 to lock with the first locking part 122. Under the locking action of the first locking part 122 and the second locking part 1121, the movement bracket 120 is stably and reliably installed in the receiving cavity 112, avoiding displacement of the movement bracket 120 in the receiving cavity 112, which would affect the installation stability and reliability of the movement.

[0036] For example, the first latching portion 122 can be a buckle, and the second latching portion 1121 can be a slot adapted to the buckle. Alternatively, the first latching portion 122 can be a slot, and the second latching portion 1121 can be a buckle adapted to the slot.

[0037] like Figure 2 As shown in the above embodiments of this application, at least two of the first latching portion 122 and the second latching portion 1121 are provided. Two or more of the first latching portions 122 are spaced apart along the circumferential direction of the mechanism support 120, and two or more of the second latching portions 1121 are spaced apart along the inner circumferential direction of the housing 110.

[0038] In this embodiment, by setting the number of both the first latching portion 122 and the second latching portion 1121 to at least two, the two or more first latching portions 122 are arranged at intervals along the circumference of the movement bracket 120, and the two or more second latching portions 1121 are arranged at intervals along the inner circumference of the housing 110, so as to further enhance the latching effect between the movement bracket 120 and the cavity wall of the receiving cavity 112, thereby further improving the installation stability and reliability of the movement bracket 120, and further ensuring the installation stability and reliability of the movement.

[0039] like Figure 2As shown, in any of the above embodiments of this application, the electric toothbrush handle 100 further includes a charging bracket 140, which is disposed in the receiving cavity 112. The end of the charging bracket 140 away from the opening 111 is provided with a third locking part 141, and the cavity wall of the receiving cavity 112 is provided with a fourth locking part 1122 that is locked with the third locking part 141.

[0040] In this embodiment, a third latching portion 141 is provided at the end of the charging bracket 140 away from the opening 111, and a fourth latching portion 1122 is provided on the cavity wall of the receiving cavity 112 to latch the third latching portion 141. Under the latching action of the third latching portion 141 and the fourth latching portion 1122, the charging bracket 140 is stably and reliably installed in the receiving cavity 112, avoiding displacement of the charging bracket 140 in the receiving cavity 112, which would affect the installation stability and reliability of the charging interface.

[0041] For example, the third latching portion 141 can be a buckle, and the fourth latching portion 1122 can be a slot adapted to the buckle. Alternatively, the third latching portion 141 can be a slot, and the fourth latching portion 1122 can be a buckle adapted to the slot.

[0042] like Figure 2 As shown in the above embodiments of this application, at least two third latching portions 141 and four fourth latching portions 1122 are provided. Two or more third latching portions 141 are spaced apart along the circumference of the charging bracket 140, and two or more fourth latching portions 1122 are spaced apart along the inner circumference of the housing 110.

[0043] In this embodiment, by setting the number of both the third latching portion 141 and the fourth latching portion 1122 to at least two, the two or more third latching portions 141 are arranged at intervals along the circumference of the charging bracket 140, and the two or more fourth latching portions 1122 are arranged at intervals along the inner circumference of the housing 110, so as to further enhance the latching effect between the charging bracket 140 and the cavity wall of the receiving cavity 112, thereby further improving the installation stability and reliability of the charging bracket 140, and further ensuring the installation stability and reliability of the charging interface.

[0044] like Figure 2 As shown in the above embodiments of this application, the electric toothbrush handle 100 further includes a cover 150, which is connected to one end of the charging bracket 140 near the opening 111 and is used to cover the opening 111. The charging bracket 140 is provided with a fifth snap-fit ​​part at one end near the opening 111, and the cover 150 is provided with a sixth snap-fit ​​part that snaps into the fifth snap-fit ​​part.

[0045] In this embodiment, a fifth latching part is provided at one end of the charging bracket 140 near the opening 111, and a sixth latching part is provided on the cover 150 to latch the fifth latching part. Under the latching action of the fifth latching part and the sixth latching part, the cover 150 is stably installed at one end of the charging bracket 140 near the opening 111, thereby stably sealing the opening 111 with the cover 150.

[0046] For example, the fifth latching part can be a latching slot, and the sixth latching part can be a buckle that latches with the fifth latching part. Alternatively, the fifth latching part can be a buckle, and the sixth latching part can be a latching slot that latches with the fifth latching part.

[0047] like Figure 4 As shown in the figure, this application embodiment also provides an electric toothbrush 1000, including the electric toothbrush handle 100 described in the above embodiments.

[0048] The electric toothbrush 1000 has the electric toothbrush handle 100 of any of the above embodiments, and therefore has all the beneficial effects of the electric toothbrush handle 100, which will not be described in detail here.

[0049] In summary, this application proposes an electric toothbrush handle 100, which includes a housing 110, a motor support 120, and a shock absorber 130.
