[0039] In the related art, an electric toothbrush 10 is a toothbrush that generates automatic and rapid bristle vibrations through electric drive to achieve a tooth cleaning effect. The electric toothbrush 10 includes a motor, a drive shaft, and a brush head 12. When the motor rotates, the motor can drive the drive shaft to move, so that the drive shaft can drive the brush head 12 to move. After the brush head 12 moves, it can clean the teeth.
[0040] The existing electric toothbrush 10 can drive the brush head 12 to perform axial movement to achieve a better cleaning effect. Among them, since the brush head 12 will inevitably encounter water during the axial movement, it may damage the motor, which further causes the electric toothbrush 10 to not work properly. For this reason, the present application proposes a toothbrush handle 11.
[0041] Please refer to Figures 1 to 3, in some embodiments, the toothbrush handle 11 includes: a housing 100, a seal 200, and a drive mechanism 300. The housing 100 has a storage cavity 110 and a mounting hole 120. The shape of the housing 100 can be generally cylindrical, and the housing 100 can facilitate the user's grip. When the housing 100 is cylindrical, the length direction of the housing 100 can be the axial direction of the housing 100. The storage cavity 110 and the mounting hole 120 communicate with each other, and the mounting hole 120 can be provided at one end of the housing 100. The seal 200 has a movement hole 210, and the seal 200 is sealingly disposed in the mounting hole 120. The specific manner in which the seal 200 is sealingly disposed in the mounting hole 120 can be that the seal 200 abuts against the hole wall of the mounting hole 120, and the seal 200 and the mounting hole 120 are in interference fit. The drive mechanism 300 is disposed in the storage cavity 110. The drive mechanism 300 includes a drive member 310 and a movement member 320, and the drive member 310 can be a motor. The movement member 320 is used to connect to the toothbrush head 12. That is, after the movement member 320 is connected to the toothbrush head 12, when the movement member 320 moves, it can drive the toothbrush head 12 to move. The movement member 320 is slidably disposed in the movement hole 210, that is, the movement member 320 can move in the movement hole 210. And the movement member 320 is sealingly connected to the seal 200. After the movement member 320 and the seal 200 are sealingly connected, it can effectively prevent water from entering the movement hole 210. The drive member 310 is connected to the movement member 320, and the drive member 310 is used to drive the movement member 320 to move relative to the seal 200 along the length direction of the housing 100. The seal 200 is sealingly disposed in the mounting hole 120. In this way, the seal 200 and the housing 100 are sealingly connected, and the seal 200 can effectively prevent water from entering the storage cavity 110 from the mounting hole 120. Further, the movement member 320 of the drive mechanism 300 is sealingly connected to the seal 200. Therefore, the seal 200 further effectively prevents water from entering the storage cavity 110 from the movement hole 210. In this way, the setting of the seal 200 can effectively prevent water from entering the storage cavity 110, thereby damaging the drive member 310, and the toothbrush handle 11 can be used normally. Specifically, the toothbrush handle 11 can have high reliability.
[0042] Further, please refer to Figure 2 and Figure 3, in some embodiments, the moving member 320 includes a first body portion 321 and a first protruding portion 322. The first protruding portion 322 is connected to the first body portion 321, and the first protruding portion 322 protrudes relative to the first body portion 321. The first protruding portion 322 and the first body portion 321 together form a groove 323. Specifically, the first protruding portion 322 and the first body portion 321 together forming the groove 323 may be that two first protruding portions 322 and one first body portion 321 together form the groove 323. The seal 200 includes a second body portion 211 and a second protruding portion 212. The second body portion 211 has a movement hole 210, the second protruding portion 212 is connected to the hole wall of the movement hole 210, and the second protruding portion 212 protrudes relative to the hole wall of the movement hole 210. The second protruding portion 212 is slidably disposed in the groove 323, and the first protruding portion 322 is connected to the second body portion 211. Specifically, the first protruding portion 322 being connected to the second body portion 211 may be that the first protruding portion 322 abuts against the second body portion 211, so that they are tightly connected to effectively prevent water from entering the storage cavity 110. Among them, since the moving member 320 can move relative to the seal 200 along the length direction of the housing 100, when the second protruding portion 212 is slidably disposed in the groove 323, on the one hand, the second protruding portion 212 can move relative to the groove 323, and on the other hand, when the second protruding portion 212 moves to the edge of the groove 323, the second protruding portion 212 will abut against the groove wall of the groove 323, thereby achieving the effect of restricting the continuous movement of the moving member 320. That is, the cooperation between the second protruding portion 212 and the groove 323 can limit the movement of the moving member 320, which can effectively prevent the moving member 320 from having an excessive movement stroke and damaging the teeth during the movement of the brush head 12.
[0043] Further, please refer to Figure 2 and Figure 3 , in some embodiments, a plurality of grooves 323 are provided, and the plurality of grooves 323 are spaced along the length direction of the moving member 320. Specifically, after the plurality of grooves 323 are spaced along the length direction of the moving member 320, the plurality of grooves 323 can cooperate with one second protruding portion 212, that is, after the second protruding portion 212 disengages from one groove 323, the second protruding portion 212 will enter another groove 323. In this way, the movement stroke of the moving member 320 can be further restricted. In addition, the number of the second protruding portions 212 can also be set to be multiple, and each second protruding portion 212 can be disposed in one groove 323, and such a setting can also further improve the effect of limiting the movement of the moving member 320.
[0044] Further, please refer to Figure 2 and Figure 3, in some embodiments, the groove 323 is an annular groove 323 extending circumferentially along the moving member 320. Specifically, when the groove 323 is an annular groove 323, when installing the moving member 320 into the moving hole 210, the moving member 320 does not need to be rotated, and the second protrusion 212 is arranged in the groove 323 because the groove 323 is an annular structure. If the groove 323 is not an annular structure, for example, the groove 323 is arranged at a local position on the moving member 320, then when installing the moving member 320 into the moving hole 210, the moving hole 210 needs to be rotated to align the surface of the moving member 320 with the groove 323, which will reduce the installation efficiency.
[0045] Further, please refer to Figure 2 and Figure 3 , in some embodiments, the second protrusion 212 surrounds and is connected to the hole wall of the moving hole 210 along the circumferential direction of the moving member 320. Specifically, the shape of the second protrusion 212 can be annular, and the shape of the groove 323 can be annular. Thus, the contact area between the second protrusion 212 and the groove 323 is relatively large, and the relatively large contact area between the second protrusion 212 and the groove 323 can improve the effect of limiting the moving member 320.
[0046] Further, the following introduces how the driving mechanism 300 drives the moving member 320 to move along the length direction of the housing 100. Please refer to Figure 4 and Figure 5 , in some embodiments, the driving mechanism 300 further includes a first gear 330, a second gear 340 and a rotating member 350. The first gear 330 is provided with first helical teeth, the second gear 340 is provided with second helical teeth, and the first helical teeth and the second helical teeth mesh. After the first helical teeth and the second helical teeth mesh, the first gear 330 can drive the second gear 340 to rotate. The first gear 330 is connected to the driving member 310, the second gear 340 has a rotating shaft 341, and the rotating shaft 341 is located at the middle position of the second gear 340. One end of the rotating member 350 is fixedly connected to the rotating shaft 341, and the other end of the rotating member 350 is rotatably connected to the moving member 320. The driving member 310 can drive the first gear 330 to rotate, so that the first gear 330 drives the second gear 340 to rotate. Further, the second gear 340 drives the rotating member 350 to rotate, and when the rotating member 350 rotates, it can drive the moving member 320 to move, so that the moving member 320 moves relative to the seal 200 along the length direction of the housing 100. Specifically, through the cooperation of the first gear 330 and the second gear 340, the rotation of the driving member 310 (the rotation of the motor) can be converted into the movement of the moving member 320 along the length direction of the housing 100. Among them, the toothbrush will be driven by the moving member 320 to move, which can improve the brushing efficiency. At the same time, the structure of the driving mechanism 300 is simple, which is convenient for assembly and has a low cost.
[0047] Further, please refer to Figure 4 and Figure 5 , in some embodiments, the drive mechanism 300 further includes an intermediate member 360. One end of the intermediate is rotatably connected to the rotating member 350, and the other end of the intermediate member 360 is rotatably connected to the moving member 320. Specifically, after the intermediate member 360 is provided, this can effectively reduce the swing of the moving member 320 in the radial direction of the housing 100, so that the movement of the moving member 320 in the length direction of the housing 100 is smoother and more stable. Among them, it should be added that after the sealing member 200 is provided with the movement hole 210, when the moving member 320 is located in the movement hole 210, the movement hole 210 can also play a guiding role for the moving member 320.
[0048] Further, the following introduces how the other end of the intermediate member 360 is rotatably connected to the moving member 320. Please refer to Figure 4 and Figure 5 , in some embodiments, the drive mechanism 300 further includes a pin shaft 370. The other end of the intermediate member 360 is provided with a first through hole 361, and the moving member 320 is provided with a second through hole 324. The pin shaft 370 passes through the first through hole 361 and the second through hole 324. After the pin shaft 370 passes through the first through hole 361 and the second through hole 324, the other end of the intermediate member 360 and the moving member 320 can be rotatably connected. In addition, it should be noted that the rotational connection between the rotating member 350 and one end of the intermediate member 360 can also be achieved in the above manner, and will not be elaborated here.
[0049] Further, in some embodiments, the material of the sealing member 200 is rubber. Among them, the rubber material has a low elastic modulus and a large elongation deformation ability, and can maintain elasticity within a wide temperature range (-50 to 150 °C). This high elasticity enables the rubber sealing member 200 to adapt to various size and shape changes, so as to maintain a good sealing effect. That is, when the sealing member 200 can closely abut against the hole wall of the mounting hole 120, it has a good sealing effect. The rubber sealing member 200 can effectively isolate the medium and avoid leakage and seepage. The rubber material can resist oxidation and corrosion erosion, and maintain the stability and reliability of its performance. The rubber material has a wide source and relatively low production cost. Specifically, after the sealing member 200 is made of rubber, it has a good sealing effect, a long service life and a low manufacturing cost.
[0050] Further, please refer to Figure 6 and Figure 7, in some embodiments, the electric toothbrush 10 includes: a brush head 12 and the toothbrush handle 11 of any one of the above embodiments, and the toothbrush handle 11 and the brush head 12 are detachably connected. The seal 200 is sealingly disposed in the mounting hole 120. Thus, the seal 200 is sealingly connected to the housing 100. The seal 200 can effectively prevent water from entering the storage cavity 110 through the mounting hole 120. Further, the moving member 320 of the drive mechanism 300 is sealingly connected to the seal 200. Therefore, the seal 200 further effectively prevents water from entering the storage cavity 110 through the moving hole 210. Thus, the arrangement of the seal 200 can effectively prevent water from entering the storage cavity 110, thereby preventing the drive member 310 from being damaged, and the toothbrush handle 11 can be used normally. Specifically, the toothbrush handle 11 can have high reliability. Further, the electric toothbrush 10 having the toothbrush handle 11 also has high reliability. In addition, it should be noted that since the toothbrush handle 11 and the brush head 12 are detachably connected, after long-term use of the electric toothbrush 10, the brush head 12 can be replaced, thereby effectively improving the cleaning effect of the electric toothbrush 10 on the teeth.
[0051] The embodiments of the present invention have been described in detail above with reference to the accompanying drawings. However, the present invention is not limited to the above embodiments. Various changes can be made without departing from the spirit of the present invention within the knowledge of those of ordinary skill in the art to which the present invention pertains. In addition, the embodiments of the present invention and the features in the embodiments can be combined with each other without conflict.
