[0047] The embodiments of the present invention are described in detail below, and examples of the embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals throughout represent the same or similar elements or elements having the same or similar functions. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain the present invention, and cannot be understood as limiting the present invention.

[0048] like Figures 1 to 9 As shown, this embodiment provides an electric toothbrush, which includes a housing 100, a support member 200, a buffer member 300, a transmission member 400, a vibrator 500 and a brush head 600. The support member 200 is arranged in the housing 100; the buffer member 300 is arranged between the support member 200 and the housing 100; one end of the transmission member 400 is fixed to the support member 200, and the other end passes through the housing 100; the vibrator 500 is fixed to the support member 200, and can drive the support member 200 to vibrate to drive the transmission member 400 to vibrate; the brush head 600 can be relatively fixed to the transmission member 400. Bristles are arranged at the end of the brush head 600, and the vibration of the brush head 600 eventually drives the bristles to vibrate to assist in completing the brushing action.

[0049] With the help of the above-mentioned arrangement, the vibration generated by the vibrator 500 is transmitted to the transmission member 400 through the support member 200, and the brush head 600 is driven to vibrate through the transmission member 400, so that brushing can be performed; a buffer member 300 is connected between the support member 200 and the shell 100, so as to buffer the vibration generated by the vibrator 500 and weaken the vibration transmitted to the shell 100, thereby reducing the vibration feeling of the user when holding the shell 100, thereby improving the use experience.

[0050] To improve the transmission efficiency, in some embodiments, the transmission member 400 is embedded in the support member 200. The transmission member 400 and the support member 200 are integrally formed. Specifically, the transmission member 400 and the support member 200 are connected by an in-mold injection molding process. The in-mold injection molding process can achieve a tight and seamless connection between the transmission member 400 and the support member 200, so that the transmission member 400 has a stronger vibration sense, which is conducive to improving the vibration effect of the brush head 600.

[0051] In some embodiments, the transmission member 400 is a rod-shaped structure. A limiting ring groove is provided at one end where the transmission member 400 and the support member 200 are connected. The support member 200 is provided with a mounting groove, and the side wall of the mounting groove protrudes inward with a limiting protrusion 110. The transmission member 400 is inserted into the mounting groove, and the limiting protrusion 110 is inserted into the limiting ring groove. The limiting ring groove is arranged around the axis of the transmission member 400. The above arrangement, on the one hand, can increase the contact area between the transmission member 400 and the support member 200, thereby improving the firmness of the connection between the two; on the other hand, the axial movement between the transmission member 400 and the support member 200 can also be limited by the structure of the limiting protrusion 110 and the limiting ring groove, so as to prevent the transmission member 400 and the support member 200 from axially disengaging during the process of plugging and unplugging the brush head 600.

[0052] Combination Figure 3As shown, in order to improve the connection relationship between the brush head 600 and the transmission member 400, in some embodiments, the brush head 600 is provided with a plug hole, the other end of the transmission member 400 can be plugged into the plug hole, and the brush head 600 and the transmission member 400 can be relatively fixed. Specifically, there is friction between the plug hole and the transmission member 400 to prevent the brush head 600 and the transmission member 400 from being easily separated. Further, the end of the transmission member 400 is provided with a plug-in portion 410 along its own axial direction, the brush head 600 includes a brush body 610 and a connecting member 620 connected to each other, the plug-in hole is provided in the connecting member 620, the plug-in portion 410 can be plugged into the plug-in hole, the opening of the connecting member 620 and the plug-in hole is provided with an elastic connecting portion 621 and a clamping protrusion 622 provided at one end of the elastic connecting portion 621, the transmission member 400 is provided with a clamping ring 420, and the elastic connecting portion 621 applies elastic force so that the clamping protrusion 622 is clamped in the clamping ring 420. A first inclined surface 430 is provided on the side wall of the clamping ring 420 away from the vibrating member 500, and the first inclined surface 430 is inclined inwardly in the direction close to the vibrating member 500, and a second inclined surface 440 is provided at the corresponding position of the side wall of the transmission member 400 and the clamping protrusion 622, and the second inclined surface 440 is inclined outwardly in the direction close to the vibrating member 500.

[0053] The material of the transmission member 400 is metal. Specifically, the transmission member 400 is preferably made of stainless steel. In other embodiments, the transmission member 400 may also be made of plastic. The material of the support member 200 is plastic.

[0054] Combination Figure 2 , Figure 4 and Figure 5 As shown, the buffer member 300 includes a first elastic member 310 and a second elastic member 320. The first elastic member 310 is clamped between the support member 200 and the shell 100, and is located at an end of the support member 200 close to the brush head 600; the second elastic member 320 is clamped between the support member 200 and the shell 100, and is located at an end of the support member 200 away from the brush head 600.

[0055] Combination Figure 4 and Figure 5 As shown, the first elastic member 310 is annular, and the first elastic member 310 is sleeved on the support member 200, and at least part of the first elastic member 310 is sandwiched between the housing 100 and the support member 200. A sealing groove 211 is provided at one end of the support member 200 away from the brush head 600, and an annular cavity is formed between the sealing groove 211 and the inner side wall of the housing 100, and the second elastic member 320 is arranged in the annular cavity. The above arrangement allows both ends of the support member 200 to be buffered by the elastic member, thereby greatly reducing the vibration transmitted to the housing 100; at the same time, the arrangement of the first elastic member 310 sleeved on the transmission member 400 allows the first elastic member 310 and the transmission member 400 to be effectively sealed, thereby preventing water from entering the housing 100 at this point.

[0056] In order to improve the stability of the first elastic member 310, the first elastic member 310 is provided with an annular groove 311, and the opening of the annular groove 311 faces the brush head 600; an annular stopper 120 extends inwardly from the upper opening of the housing 100 facing the brush head 600, and an annular protrusion 130 extends downward from the inner end of the annular stopper 120, and the annular protrusion 130 is inserted into the annular groove 311. Specifically, the annular protrusion 130 is inserted into the bottom of the annular groove 311. This arrangement enables effective sealing between the housing 100 and the first elastic member 310 to prevent water from entering the interior of the housing 100 at this point.

[0057] It should be noted that the housing 100 has an installation cavity and an upper opening and a lower opening communicating with the installation cavity. The lower opening is blocked by a blocking member 150 , and the support member 200 is disposed in the installation cavity.

[0058] The support member 200 includes a support body 210 and a support end 220. The support end 220 is located at one end of the support body 210 close to the brush head 600. The outer diameter of the support end 220 is smaller than the outer diameter of the support body 210. The first elastic member 310 is annular. The first elastic member 310 is sleeved on the support end 220 and abuts against the end surface of the support body 210 close to the support end 220. With this arrangement, when installing, the first elastic member 310 is sleeved on the support end 220, and when the first elastic member 310 abuts against the support body 210, feedback that the installation is in place can be clearly obtained, thereby improving the installation efficiency and the accuracy of the relative position between the first elastic member 310 and the support member 200.

[0059] Combination Figure 6 and Figure 7 As shown, in order to improve the connection strength between the support member 200 and the housing 100, a buckle is provided on the support member 200, and the buckle includes a third elastic member 230 and a clamping portion 240. The housing 100 is provided with a clamping slot 140, and the third elastic member 230 applies elastic force to the clamping portion 240 so that the clamping portion 240 is clamped in the clamping slot 140. The above arrangement strengthens the connection between the housing 100 and the support member 200; at the same time, the vibration of the support member 200 is buffered by the third elastic member 230, further reducing the vibration of the housing 100 and improving the user experience. The buckle is located between the first elastic member 310 and the second elastic member 320.

[0060] Further, the third elastic member 230 includes an elastic rod, one end of which is arranged on the support member 200, and the clamping portion 240 is arranged on the other end of the elastic rod. This arrangement has a simple structure and is easy to produce. Specifically, the clamping groove 140 is arranged inside the housing 100, and the clamping portion 240 is provided with a guide surface 241, which is inclined inwardly in the direction close to the brush head 600, so that when the support member 200 is installed inside the housing 100, it only needs to be pushed in the direction of the brush head 600, and the clamping portion 240 with the guide surface 241 is pressed against the inner wall of the housing 100, and the elastic rod is caused to bend. When the support member 200 moves into place, the clamping portion 240 is reset under the action of the elastic rod, so that the clamping portion 240 is clamped in the clamping groove 140. One end of the elastic rod is provided with a toggle portion 242, and toggling the toggle portion 242 can cause the engaging portion 240 to be disengaged from the engaging slot 140, so as to complete the disassembly of the supporting member 200 and the housing 100 and improve the disassembly efficiency.

[0061] Combination Figure 4 As shown, to ensure effective transmission of vibration, the distance L between the vibration member 500 and the transmission member 400 is less than or equal to 10 mm. Figure 8 and Fig. 9 As shown, in some embodiments, the vibration member 500 is snap-connected to the support member 200. The vibration member 500 includes a driving member 510 and an eccentric member 520, and the eccentric member 520 is arranged on the output shaft of the driving member 510. The driving member 510 is a hollow cup motor. The support member 200 is provided with a placement groove, which is perpendicular to the axial direction of the shell 100. The support member 200 is provided with two relative elastic protrusions 260 at the opening of the placement groove. The distance between the free ends of the two elastic protrusions 260 is smaller than the outer diameter of the driving member 510 in a natural state. During installation, the free ends of the two elastic protrusions 260 are separated from each other so that the driving member 510 is placed in the placement groove. After the driving member 510 is placed, the free ends of the two elastic protrusions 260 return to a natural state. In the axial direction of the shell 100, a first limiting portion 251 and a second limiting portion 252 are provided in the support member 200, and the first limiting portion 251 and the second limiting portion 252 respectively abut against the two ends of the driving member 510, that is, the driving member 510 is clamped between the first limiting portion 251 and the second limiting portion 252 in the axial direction of the shell 100.
