[0034] Electric toothbrushes use the rapid rotation or vibration of the motor movement to produce high-frequency vibrations in the brush head, instantly breaking down the toothpaste into fine foam and deeply cleaning the gaps between teeth. At the same time, the vibration of the bristles can promote blood circulation in the mouth and have a massage effect on the gum tissue.
[0035] The handle of the electric toothbrush currently on the market is set outside the movement bracket, and the handle is threadedly connected to the bottom cover. When assembling the bottom cover and the handle, the bottom cover needs to be rotated relative to the handle for multiple circles to complete the assembly, resulting in a slow assembly speed of the handle and the bottom cover.
[0036] To solve the above problems, please refer to Figures 1 to 4 The handle 110 assembly proposed by the utility model includes:
[0037] A handle 110, wherein a receiving cavity 110a is provided in the handle 110;
[0038] The movement bracket 120 is provided with a clamping arm 121, the clamping arm 121 includes a first clamping protrusion 1211 and a second clamping protrusion 1212, the movement bracket 120 is located in the accommodating cavity 110a, and the first clamping protrusion 1211 is clamped with the inner wall of the handle 110; and
[0039] The bottom cover 130 includes a clamping portion 131 . The clamping portion 131 is located in the accommodating cavity 110 a . The second clamping protrusion 1212 is clamped with the clamping portion 131 .
[0040] The technical solution of the utility model adopts the method of providing a clamping arm 121 on the movement bracket 120, and providing a first clamping protrusion 1211 and a second clamping protrusion 1212 on the clamping arm 121, and the handle 110 and the bottom cover 130 are respectively clamped with the first clamping protrusion 1211 and the second clamping protrusion 1212, so as to realize the connection between the bottom cover 130 and the handle 110. During assembly, the assembly can be completed by simply snapping the handle 110 and the bottom cover 130 with the clamping arm 121, thereby avoiding the problem of low assembly efficiency caused by rotating the bottom cover 130 relative to the handle 110 for multiple turns due to threaded assembly.
[0041] In one embodiment, please refer to Figure 1 The first clamping protrusion 1211 and the second clamping protrusion 1212 are respectively located at opposite sides of the clamping arm 121 .
[0042] In this embodiment, in order to avoid the first clamping protrusion 1211 and the second clamping protrusion 1212 being located on the same side of the clamping arm 121, the elastic force applied by the handle 110 to the first clamping protrusion 1211 and the clamping portion 131 to the second clamping protrusion 1212 being in the same direction, causing the clamping arm 121 to be broken due to excessive elastic force, the first clamping protrusion 1211 and the second clamping protrusion 1212 are respectively arranged on opposite sides of the clamping arm 121.
[0043] In one embodiment, please refer to Figure 2 The first clamping protrusion 1211 and / or the second clamping protrusion 1212 have an inclined surface section 1213 and an abutting section 1214 connected to each other, and the height of the inclined surface section 1213 increases successively in a direction approaching the abutting section 1214 .
[0044] In this embodiment, the inclined surface section 1213 is used to provide a deformation space toward the inclined surface section 1213 when the abutting section 1214 is engaged with the handle 110 or the engaging portion 131 .
[0045] In one embodiment, please refer to Figure 1 and Figure 2 The movement bracket 120 also includes a battery rack interconnected with the clamping arm 121, the height of the inclined section 1213 of the first clamping protrusion 1211 increases successively in the direction approaching the battery rack, and the height of the inclined section 1213 of the second clamping protrusion 1212 increases successively in the direction away from the battery rack.
[0046] In this embodiment, the height of the inclined surface section 1213 of the first clamping protrusion 1211 increases successively in the direction approaching the battery rack, and the height of the inclined surface section 1213 of the second clamping protrusion 1212 increases successively in the direction away from the battery rack, that is, the inclined surfaces of the first clamping protrusion 1211 and the second clamping protrusion 1212 extend in opposite directions, and the end of the abutment section 1214 away from the inclined surface faces the opposite position. Therefore, the first clamping protrusion 1211 and the second clamping protrusion 1212 work together to constrain the axial displacement of the movement bracket 120 along the handle 110.
[0047] In one embodiment, please refer to Figure 1 The inner wall of the handle 110 is provided with a first clamping groove 110b, and the first clamping protrusion 1211 is clamped in the first clamping groove 110b;

[0049] In this embodiment, the first engaging groove 110b and the second engaging groove 131a respectively match the shapes of the first engaging protrusion 1211 and the second engaging protrusion 1212. Preferably, when both the first engaging protrusion 1211 and the second engaging protrusion 1212 have an inclined surface section 1213 and an abutting section 1214, the abutting section 1214 abuts against the groove wall of the first engaging groove 110b or the second engaging groove 131a, and the inclined surface section 1213 is used to guide the abutting section 1214 into the first engaging groove 110b or the second engaging groove 131a, thereby playing a positioning role of the engaging fit.
[0050] In one embodiment, please refer to Figure 3 The bottom cover 130 further includes a limiting protrusion 132 , which is located in the accommodating cavity 110 a and connected to the clamping portion 131 . The limiting protrusion 132 is used to limit the rotation of the bottom cover 130 relative to the movement bracket 120 .
[0051] In this embodiment, in order to restrict the bottom cover 130 from rotating around the movement bracket 120, a limiting protrusion 132 is provided on the bottom cover 130 to abut against the movement bracket 120. In this embodiment, a limiting groove that cooperates with the limiting protrusion 132 can be provided on the movement bracket 120, and the limiting protrusion 132 is located in the limiting groove, thereby achieving the effect of restricting the bottom cover 130 from rotating around the movement bracket 120. In other embodiments, the specific limiting method is not limited.
[0052] In one embodiment, please refer to Figure 3 and Figure 4 There are two limiting protrusions 132 , and the two limiting protrusions 132 are respectively connected to the two sides of the clamping portion 131 and respectively abut against the two sides of the clamping arm 121 , thereby restricting the bottom cover 130 from rotating relative to the movement bracket 120 .

In addition, the limiting protrusion 132 is provided with two limiting grooves for accommodating the two sides of the clamping arm 121, and the side walls of the two sides of the clamping arm 121 are respectively located in the two limiting grooves, further restricting the bottom cover 130 from rotating relative to the movement bracket 120.
[0054] In one embodiment, please refer to Figure 1 A positioning groove is provided in the accommodating cavity 110a, and the movement bracket 120 further includes a positioning protrusion 122. The positioning protrusion 122 and the clamping arm 121 are located on the same side, and the positioning protrusion 122 is located in the positioning groove.
[0055] In this embodiment, the positioning protrusion 122 on the movement bracket 120 is installed along the positioning groove in the handle 110 to align the first clamping protrusion 1211 with the first clamping groove 110b, which simplifies the process of aligning the first clamping protrusion 1211 to a preset position when assembling the movement bracket 120.
[0056] In one embodiment, please refer to Figure 1 The bottom cover 130 further includes a body 133 interconnected with the clamping portion 131. The body 133 is at least partially located in the accommodating cavity 110a. An annular groove 133a is provided on the outer periphery of the body 133 for placing a sealing ring.
[0057] In this embodiment, an annular groove 133a is provided on the main body 133 and a sealing ring is provided in the annular groove 133a, thereby preventing water outside the accommodating cavity 110a from entering the accommodating cavity 110a along the gap between the bottom cover 130 and the inner wall of the handle 110, thereby improving the sealing performance of the bottom cover 130.
