In addition, the terms "first", "second", and "third" are used for descriptive purposes only, and cannot be understood as indicating or implying relative importance.
[0033] In addition, the technical features involved in the different embodiments of the present invention described below can be combined with each other as long as they do not conflict with each other.
[0034] The utility model embodiment discloses a drive assembly for a toothbrush head 13, such as Figure 1-11 As shown, it includes: a first drive bracket 1 and a second drive bracket 2 that are detachably connected, a drive motor 3, a driving wheel 4 and a driven wheel 5 are installed between the first drive bracket 1 and the second drive bracket 2, the driving wheel 4 is sleeved on the output shaft of the drive motor 3, the driven wheel 5 is meshed with the driving wheel 4, and the driven wheel 5 is rotatably connected to the second drive bracket 2; the driven wheel 5 is sleeved with a drive push rod 6, the drive push rod 6 is used to be magnetically connected to the brush head push rod 131 of the toothbrush head 13, and the brush head push rod 131 is used to drive the brush disc 132 of the toothbrush head 13 to perform reciprocating rotation. In the specific implementation process, the first drive bracket 1 and the second drive bracket 2 are fastened by screws. The brush disc 132 is rotatably connected to the toothbrush handle 133, the brush head push rod 131 is located in the toothbrush handle 133 and is hinged to the brush disc 132, and the brush head push rod 131 is embedded with a second magnet 134.
[0035] It should be noted that, through the driving action of the driving motor 3, the driving push rod 6 performs telescopic movement, so that the brush head push rod 131 drives the brush plate 132 of the toothbrush head 13 to perform reciprocating rotational movement, thereby providing a driving component for the toothbrush head 13, providing telescopic power to the brush head push rod 131 of the toothbrush head 13, and realizing rotational teeth cleaning.
[0036] like Figure 3-11 As shown, the driving push rod 6 is sleeved with a sleeve 7 at one end relative to the driven wheel 5, and the sleeve 7 is embedded with a first magnet 8 for magnetic attraction with the brush head push rod 131. It should be noted that the first magnet 8 is magnetically connected with the second magnet 134, and the driving motor 3 drives the driving wheel 4 to rotate. Since the driving wheel 4 is engaged with the driven wheel 5, the driven wheel 5 is driven to rotate; since the driven wheel 5 is sleeved with the driving push rod 6, the driving push rod 6 and the first magnet 8 are driven to perform telescopic movement. Since the first magnet 8 is magnetically connected with the brush head push rod 131, the driving push rod 6 drives the brush head push rod 131 to perform telescopic movement, thereby driving the brush disc 132 to rotate and clean teeth.
[0037] like Figure 3 , Figure 4 and Fig. 9 As shown, the driving push rod 6 is provided with a first step 61 abutting against the sleeve 7, and the sleeve 7 is provided with a second step 71. In the specific implementation process, the first step 61 is arranged in an annular shape, and the first step 61 and the driving push rod 6 are an integrally formed structure; the arrangement of the first step 61 facilitates the sleeve 7 to be sleeved and installed.
[0038] like Figure 3 , Figure 4 and Figure 8 As shown, the driving push rod 6 is sleeved with a first waterproof ring 9 , and the first waterproof ring 9 is clamped between the first driving bracket 1 and the second driving bracket 2 .
[0039] like Figure 3 , Figure 4 and Figure 8 As shown, the second waterproof ring 10 is sleeved on the driving push rod 6, and the second waterproof ring 10 is clamped between the first driving bracket 1 and the second driving bracket 2. It should be noted that, through the sealing effect of the first waterproof ring 9 and the second waterproof ring 10, the driving assembly can be waterproofed to prevent water from entering the first driving bracket 1 and the second driving bracket 2, thereby ensuring the smooth operation of the driving motor 3.
[0040] like Figure 3 , Figure 4 and Figure 8 As shown, the first waterproof ring 9 is provided with a card slot 91 in an annular arrangement, the first drive bracket 1 is provided with a first card block 11, the second drive bracket 2 is provided with a second card block 21, and the first card block 11 and the second card block 21 are enclosed and engaged in the card slot 91. In the specific implementation process, the first card block 11 and the second card block 21 are enclosed and engaged in the card slot 91, so that the first waterproof ring 9 is pressed against the inner walls of the first drive bracket 1 and the second drive bracket 2; the second waterproof ring 10 is also provided with a card slot 91 in an annular arrangement, the first drive bracket 1 is provided with two first card blocks 11, and the second drive bracket 2 is provided with two second card blocks 21.
[0041] like Figure 1-4 As shown, it also includes a rotating shaft 12, which passes through the driven wheel 5 and the driving push rod 6, and the rotating shaft 12 is respectively plugged with the first driving bracket 1 and the second driving bracket 2. In this embodiment, the driving push rod 6 is provided with a limiting groove for accommodating the rotating shaft 12 to pass through.
[0042] like Figure 3 , Figure 4 and Figure 7 As shown, the driven wheel 5 is provided with an eccentric portion 51, and one end of the driving push rod 6 is sleeved with the eccentric portion 51. In this embodiment, the driven wheel 5 and the eccentric portion 51 are an integrally formed structure; when the driven wheel 5 rotates, the eccentric portion 51 is driven to rotate; because the eccentric portion 51 is sleeved with the driving push rod 6, the driving push rod 6 is driven to perform reciprocating telescopic motion, providing telescopic power to the brush plate 132 of the toothbrush head 13. Thus, rotary cleaning is achieved.
[0043] like Figure 3-6 As shown, a rib 22 is provided inside the second driving bracket 2. In the specific implementation process, the number of the ribs 22 is set to two, and the two ribs 22 are arranged in parallel and adjacent to each other; the ribs 22 abut against the outer wall of the driving motor 3, so that the contact between the second driving bracket 2 and the driving motor 3 is a line contact, which reduces the resonance of the driving motor 3 and enhances the user experience.
[0044] like Figure 3-6 As shown, the wall surface of the rib 22 is arranged in an arc shape. It should be noted that, since the wall surface of the rib 22 is arranged in an arc shape, the contact area between the rib 22 and the outer wall of the drive motor 3 is reduced, and the resonance of the drive motor 3 is better reduced.
[0045] Working principle: through the driving action of the driving motor 3, the driving push rod 6 performs telescopic movement, so that the brush head push rod 131 drives the brush plate 132 of the toothbrush head 13 to perform reciprocating rotational movement, thereby providing a driving component for the toothbrush head 13, providing telescopic power to the brush head push rod 131 of the toothbrush head 13, and realizing rotary teeth cleaning.
[0046] Obviously, the above embodiments are merely examples for the purpose of clear explanation, and are not intended to limit the implementation methods. For those skilled in the art, other different forms of changes or modifications can be made based on the above description. It is not necessary and impossible to list all the implementation methods here. The obvious changes or modifications derived therefrom are still within the scope of protection of the invention of the utility model.
