[0067] Embodiments of the present invention are described in detail below, and the embodiments described with reference to the accompanying drawings are exemplary.

[0068] Reference below Figure 1-Figure 13 The base assembly 100 of the electric toothbrush 200 according to the embodiment of the present invention is described.

[0069] like Figure 1 and Figure 2 As shown, according to the base assembly 100 of the electric toothbrush 200 of the first aspect of the embodiment of the utility model, the electric toothbrush 200 is placed on the placement body through the base assembly 100, and the base assembly 100 includes: a base 10 and a bottom cover 20, the middle of the base 10 is provided with a charging port 11, the bottom cover 20 is arranged at the bottom of the base 10, the projection of the base 10 on the bottom cover 20 does not exceed the edge of the bottom cover 20, the bottom cover 20 can move relative to the base 10, so that the charging port 11 can be selectively opened and closed, and the bottom cover 20 is provided with a support portion 21, and the support portion 21 is suitable for supporting the placement body of the electric toothbrush 200.

[0070] Specifically, a charging port 11 is provided in the middle of the base 10 of the electric toothbrush 200, which can protect the charging port 11 and keep the position on the base 10 that is prone to mold away from the charging port 11, thereby avoiding failure of the charging port 11 and reducing the impact on the charging port 11. The bottom cover 20 is connected to the bottom of the base 10 to close the base 10 and prevent water stains from splashing into the base 10. The projection of the base 10 on the bottom cover 20 does not exceed the edge of the bottom cover 20, which can further improve the sealing of the base assembly 100. The bottom cover 20 can fully seal the base 10, thereby avoiding mold and bacterial growth on the bottom and outer edge of the base 10. In addition, under the action of external force, the bottom cover 20 can slide relative to the base 10, which has the advantage of labor-saving disassembly and installation. Moreover, the charging port 11 can be selectively opened and closed, that is, when charging is needed, the bottom cover 20 is removed to facilitate opening the charging port 11. When charging is completed, the bottom cover 20 is installed and the bottom cover 20 further seals the charging port 11, thereby improving the waterproof performance of the electric toothbrush 200.

[0071] Furthermore, the bottom cover 20 is provided with a support portion 21. The provision of the support portion 21 can play a role in strengthening support and can also increase the contact area between the bottom cover 20 and the placement body. The placement body can be a toothbrush holder or a washbasin, thereby making the base assembly 100 more stably placed and avoiding falling on the washbasin.

[0072] Therefore, the base assembly 100 of the electric toothbrush 200 can prevent the bottom cover 20 from getting moldy and bacteria growing, prevent deformation, and play a supporting and reinforcing role, so that the bottom cover 20 and the placement body of the electric toothbrush 200 can cooperate more stably.

[0073] According to some embodiments of the present invention, Figure 4 and Figure 5 As shown, the support portion 21 is the bottom surface of the bottom cover 20 .

[0074] The bottom surface of the support portion 21 is extended toward the outer edge of the base 10, so that the overall gravity of the electric toothbrush 200 is transmitted from the center of the bottom surface of the bottom cover 20 to the outside, and then transmitted to the placement body, thereby reducing the force on the bottom cover 20. The middle part of the bottom surface of the support portion 21 is disc-shaped, so that the contact area between the bottom surface of the bottom cover 20 and the placement body can be further increased, thereby further reducing the force on the bottom cover 20. Moreover, the bottom surface edge of the bottom cover 20 is bent inward, so that the bottom surface of the bottom cover 20 and the handle shell 80 can be naturally transitioned. Using the bottom surface as the support portion 21 can not only play a supporting and strengthening role, but also improve the stability of the bottom cover 20 and the placement body of the electric toothbrush 200.

[0075] According to some embodiments of the present invention, Figure 5 and Fig.10 As shown, the base 10 is formed with a plug-in slot 12 , the charging port 11 is arranged at the bottom of the plug-in slot 12 , and the bottom cover 20 is formed with a plug-in protrusion 22 , which is plugged and matched with the plug-in slot 12 .

[0076] Among them, the base 10 is provided with a plug-in groove 12, which allows the plug-in protrusion 22 to extend into the plug-in groove 12 to close the plug-in groove 12, thereby preventing water stains from flowing to the charging port 11, and the plug-in matching method is simple and convenient, which can further facilitate the matching between the base 10 and the bottom cover 20.

[0077] According to a specific embodiment of the utility model, the insertion groove 12 and the insertion protrusion 22 are interference fit, or the inner peripheral wall of the insertion groove 12 is provided with a first clamping part, and the outer peripheral wall of the insertion protrusion 22 is provided with a second clamping part, and the first clamping part and the second clamping part are clamped and fit.

[0078] Specifically, when the insertion groove 12 and the insertion protrusion 22 are interference-fitted, the connection between the insertion groove 12 and the insertion protrusion 22 can be made tighter and more stable, and the sealing performance of the base assembly 100 can be improved. When the outer peripheral wall of the insertion protrusion 22 is provided with a second clamping portion, the second clamping portion can be set as a clamping protrusion, and correspondingly, the inner peripheral wall of the insertion groove 12 is provided with a first clamping portion, and the first clamping portion can be set as a clamping groove, so that the clamping protrusion and the clamping groove are clamped and matched, so that the bottom cover 20 and the base 10 can be easily installed and removed.

[0079] According to some embodiments of the present invention, Figure 2 As shown, the base assembly 100 of the electric toothbrush 200 further includes: a first elastic seal 30 , which is disposed on the inner peripheral wall of the insertion groove 12 , and the insertion protrusion 22 is sealedly matched with the first elastic seal 30 .

[0080] The first elastic seal 30 is elastic and can be deformed. The first elastic seal 30 is located between the plug-in protrusion 22 and the inner peripheral wall of the plug-in groove 12, so that the plug-in protrusion 22 and the first elastic seal 30 can be sealed more tightly.

[0081] According to some embodiments of the present invention, Figure 2 As shown, a guide surface 40 is provided at one end of the first elastic sealing member 30 corresponding to the notch of the plug-in groove 12 , and the guide surface 40 is used to guide the plug-in protrusion 22 .

[0082] The guide surface 40 can be set as a guide slope, which can guide the insertion of the plug-in protrusion 22, thereby facilitating the insertion of the plug-in protrusion 22 into the plug-in slot 12 and avoiding interference between the plug-in protrusion 22 and the notch of the plug-in slot 12.

[0083] According to the specific embodiment of the utility model, Figure 2 As shown, the guide surface 40 is constructed as a conical surface with a decreasing cross-sectional area in the direction of the bottom of the adjacent plug-in groove 12. In this way, it is easier to use the plug-in protrusion 22 when it starts to enter the plug-in groove 12. As the plug-in protrusion 22 extends, the plug-in protrusion 22 and the inner peripheral wall of the plug-in groove 12 gradually fit more closely, thereby preventing the bottom cover 20 from falling off.

[0084] According to some embodiments of the present invention, Figure 2 As shown, the inner peripheral wall of the first elastic sealing member 30 is formed with a sealing portion 31 protruding inwardly, and the outer peripheral wall of the inserting protrusion 22 is in contact with the sealing portion 31 .

[0085] The sealing portion 31 cooperates with the outer peripheral wall of the plug-in protrusion 22 to ensure the sealing between the plug-in protrusion 22 and the sealing portion 31 , thereby preventing water stains from flowing into the plug-in groove 12 . The sealing portion 31 may be an annular sealing protrusion.

[0086] According to a specific embodiment of the present utility model, the insertion protrusion 22 forms a buckle portion 222 protruding outward, and the buckle portion 222 is snap-fitted with the sealing portion 31 .

[0087] Among them, the buckle portion 222 can be set as a protrusion, and correspondingly, the sealing portion 31 can be an annular sealing protrusion, which extends into the upper side of the sealing protrusion, and the two are snap-fitted together, so as to facilitate the installation and disassembly of the plug-in protrusion 22 and the sealing portion 31, and also play a sealing role.

[0088] According to some embodiments of the present invention, Figure 2 As shown, the base assembly 100 of the electric toothbrush 200 further includes: a second elastic seal 50 , which is disposed on the outer peripheral wall of the base 10 , and is used for sealingly cooperating with the handle shell 80 of the electric toothbrush 200 .

[0089] Among them, the second elastic sealing member 50 is located between the handle shell 80 and the outer peripheral wall of the base 10, which can make the connection between the outer peripheral wall of the base 10 and the handle shell 80 tighter and can also further play a role in sealing and waterproofing.

[0090] According to some embodiments of the present invention, Figure 2 As shown, the base assembly 100 of the electric toothbrush 200 further includes an elastic buffer 60 , which is disposed on the bottom surface of the base 10 and is disposed around the notch of the insertion slot 12 .

[0091] Among them, the elastic buffer 60 is a buffer pad, which can reduce noise when the bottom cover 20 seals and cooperates with the charging port 11. It also has a buffering effect when pinching the hand. When the toothbrush is placed vertically on the table, it also plays a buffering role, thereby preventing the internal parts of the electric toothbrush 200 from being damaged.

[0092] According to some embodiments of the present invention, the first elastic seal 30, the second elastic seal 50 and the elastic buffer 60 are integrally formed, or the first elastic seal 30 and the second elastic seal 50 are connected by a connecting piece, and the elastic buffer 60 is integrally formed with the base 10.

[0093] Among them, when the first elastic seal 30, the second elastic seal 50 and the elastic buffer 60 are integrally formed, the number of parts can be reduced, the assembly procedures can be reduced, and time can be saved, thereby improving the installation efficiency. The gaps between the various parts can also be reduced, which affects the sealing and waterproof performance of the base 10.

[0094] According to some embodiments of the present invention, the base assembly 100 of the electric toothbrush 200 also includes: a second elastic seal 50, which is arranged on the outer peripheral wall of the base 10, and the elastic seal is used to seal with the handle shell 80 of the electric toothbrush 200, so that the seal between the outer peripheral wall of the base 10 and the handle shell 80 can be tighter.

[0095] According to some embodiments of the present invention, Figure 3 As shown, the inner peripheral wall of the second elastic seal 50 is provided with a first limiting portion 51 , and the outer peripheral wall of the base 10 is provided with a second limiting portion 13 , and the first limiting portion 51 cooperates with the first limiting portion 51 in the thickness direction of the base 10 .

[0096] The first limiting portion 51 is protruded toward the outer peripheral wall of the base 10 , and the first limiting portion 51 and the second limiting portion 13 are limited and matched, thereby preventing the first limiting portion 51 and the second limiting portion 13 from moving along the axial direction of the electric toothbrush 200 .
