[0024] like Figure 1 , Figure 2 and Figure 3 As shown, an embodiment of this application provides a handle assembly 100, mainly used in electric toothbrush handles. The handle assembly 100 includes a handle cylinder 110, a drive member 120, and a seal member 130.

[0025] The handle cylinder 110 has a receiving cavity 112 with an opening 111 at one end. The driving member 120 includes a fixing part 121 and an output part 122. The fixing part 121 is disposed in the receiving cavity 112. One end of the output part 122 is connected to the fixing part 121, and the other end passes through the opening 111 and is disposed outside the handle cylinder 110. The sealing member 130 is sleeved on the output part 122. The outer peripheral wall of the sealing member 130 abuts against the inner wall of the opening 111, and the inner peripheral wall of the sealing member 130 is provided with a first annular protrusion 131 that abuts against the peripheral wall of the output part 122.

[0026] The handle assembly 100 provided in the embodiments of this application has a handle cylinder 110 with a receiving cavity 112 having an opening 111 at one end. The fixing part 121 of the drive member 120 is disposed in the receiving cavity 112. One end of the output part 122 of the drive member 120 is connected to the fixing part 121, and the other end passes through the opening 111 and is disposed outside the handle cylinder 110. A sealing member 130 is sleeved on the output part 122. By abutting the outer peripheral wall of the sealing member 130 against the inner wall of the opening 111, the gap between the inner wall of the opening 111 and the peripheral wall of the output part 122 is sealed, thereby preventing external water or dust from entering the handle assembly 100 through the gap between the inner wall of the opening 111 and the peripheral wall of the output part 122, effectively extending the service life of the drive member 120.

[0027] By providing a first annular protrusion 131 on the inner circumferential wall of the seal 130 that abuts against the circumferential wall of the output portion 122, the first annular protrusion 131 fills the tiny gap between the inner circumferential wall of the seal 130 and the circumferential wall of the output portion 122, effectively enhancing the sealing effect, further reducing the probability of external water or dust entering the handle assembly 100, and further extending the service life of the drive component 120.

[0028] For example, the drive component 120 can be a sweeping motor, and the seal 130 can be made of rubber or silicone.

[0029] like Figure 3 As shown, in one embodiment of this application, the outer peripheral wall of the sealing member 130 is provided with a second annular protrusion 132 that abuts against the inner wall of the opening 111.

[0030] In this embodiment, by providing a second annular protrusion 132 on the outer peripheral wall of the seal 130 that abuts against the inner wall of the opening 111, the second annular protrusion 132 fills the tiny gap between the outer peripheral wall of the seal 130 and the inner wall of the opening 111, effectively enhancing the sealing effect, further reducing the probability of external water or dust entering the handle assembly 100, and further extending the service life of the drive component 120.

[0031] like Figure 3 As shown, in the above embodiments of this application, two second annular protrusions 132 are provided, and the two second annular protrusions 132 are spaced apart along the axial direction of the seal 130.

[0032] In this embodiment, the sealing effect is further enhanced by setting the number of second annular protrusions 132 to two and arranging the two second annular protrusions 132 at intervals along the axial direction of the seal 130.

[0033] like Figure 3As shown, in one embodiment of this application, the inner wall of the opening 111 is provided with an annular limiting part 113 at the end away from the fixing part 121, and the end of the annular limiting part 113 near the fixing part 121 abuts against the sealing member 130.

[0034] In this embodiment, an annular limiting part 113 is provided at the end of the inner wall of the opening 111 away from the fixing part 121, and the end of the annular limiting part 113 near the fixing part 121 abuts against the sealing member 130. Under the abutment action of the annular limiting part 113 against the sealing member 130, the sealing member 130 is restricted from moving away from the fixing part 121, thereby preventing the sealing member 130 from falling out of the opening 111 and causing the sealing function to fail, thus ensuring the stability of the sealing function.

[0035] like Figure 3 As shown in the above embodiments of this application, the sealing member 130 is provided with a third annular protrusion 133 at one end away from the fixing part 121, and the third annular protrusion 133 abuts against the end of the annular limiting part 113 near the fixing part 121.

[0036] In this embodiment, by providing a third annular protrusion 133 at the end of the seal 130 away from the fixing part 121, and abutting the third annular protrusion 133 against the end of the annular limiting part 113 near the fixing part 121, the third annular protrusion 133 fills the tiny gap between the end wall of the end of the seal 130 away from the fixing part 121 and the third annular protrusion 133, thereby further enhancing the sealing effect, further reducing the probability of external water or dust entering the handle assembly 100, and further extending the service life of the drive component 120.

[0037] like Figure 3 As shown in the above embodiment of this application, the sealing member 130 has a first protrusion 134 protruding from one end away from the fixing part 121. The first protrusion 134 abuts against the circumferential wall of the output part 122 and the inner circumferential wall of the annular limiting part 113 to seal the gap between the circumferential wall of the output part 122 and the inner circumferential wall of the annular limiting part 113. This prevents external water or dust from entering the handle assembly 100 through the gap between the circumferential wall of the output part 122 and the inner circumferential wall of the annular limiting part 113, effectively extending the service life of the driving member 120.

[0038] like Figure 2 and Figure 3As shown in the above embodiments of this application, the handle assembly 100 further includes a bracket 140, which is disposed within the receiving cavity 112. The fixing part 121 is disposed on the bracket 140, and one end of the bracket 140 near the opening 111 abuts against the end of the sealing member 130 away from the annular limiting part 113. Specifically, the end of the bracket 140 near the opening 111 is provided with a second protrusion 141, and the end of the sealing member 130 away from the annular limiting part 113 is provided with a recess 135 that matches the shape of the second protrusion 141.

[0039] In this embodiment, a second protrusion 141 is provided at one end of the bracket 140 near the opening 111, and a recess 135 adapted to the shape of the second protrusion 141 is provided at one end of the seal 130 away from the annular limiting part 113. This restricts the seal 130 from moving towards the fixing part 121 under the abutment action of the second protrusion 141 against the recess 135, thereby preventing the seal 130 from falling out of the opening 111 into the receiving cavity 112 and causing the sealing function to fail, thus ensuring the stability of the sealing function.

[0040] This application also provides an electric toothbrush handle, including the handle assembly 100 described in the above embodiments.

[0041] The electric toothbrush handle has the handle assembly 100 of any of the above embodiments, and therefore has all the beneficial effects of the handle assembly 100, which will not be described in detail here.

[0042] This application also provides an electric toothbrush, including the electric toothbrush handle described in the above embodiments.

[0043] The electric toothbrush has the electric toothbrush handle of the above embodiments, and therefore has all the beneficial effects of an electric toothbrush handle, which will not be described in detail here.

[0044] In summary, this application proposes a handle assembly 100, which includes a handle cylinder 110, a drive member 120, and a sealing member 130. The handle cylinder 110 has a receiving cavity 112 with an opening 111 at one end. The fixing part 121 of the drive member 120 is disposed in the receiving cavity 112. One end of the output part 122 of the drive member 120 is connected to the fixing part 121, and the other end passes through the opening 111 and is disposed outside the handle cylinder 110. The sealing member 130 is sleeved on the output part 122. By abutting the outer peripheral wall of the sealing member 130 against the inner wall of the opening 111, the gap between the inner wall of the opening 111 and the peripheral wall of the output part 122 is sealed, thereby preventing external water or dust from entering the handle assembly 100 through the gap between the inner wall of the opening 111 and the peripheral wall of the output part 122, effectively extending the service life of the drive member 120. By providing a first annular protrusion 131 on the inner circumferential wall of the seal 130 that abuts against the circumferential wall of the output portion 122, the first annular protrusion 131 fills the tiny gap between the inner circumferential wall of the seal 130 and the circumferential wall of the output portion 122, effectively enhancing the sealing effect, further reducing the probability of external water or dust entering the handle assembly 100, and further extending the service life of the drive component 120.
