[0037] Figure 1 Disclosed is a toothbrush system 100, which includes an electric toothbrush 1 and a storage box 2 for accommodating the electric toothbrush 1. The electric toothbrush 1 can be placed in the storage box 2, and when the electric toothbrush 1 is placed in the storage box 2, the storage box 2 can charge the electric toothbrush 1. Furthermore, charging contacts are provided on the storage box 2 and the electric toothbrush 1, and the electric toothbrush 1 can be charged in addition to being placed in the storage box 2 for charging, and the electric toothbrush 1 can also be charged separately.

[0038] refer to Figure 2-14, the figure discloses an electric toothbrush 1, which includes a main body 11 and a brush head 12. The brush head 12 is generally detachably mounted on the main body 11. Referring to the position of the toothbrush in the figure, the upright direction of the toothbrush is taken as the up-down direction, and the upper ends of the motor 14, the housing 13, etc. refer to the upper part in the figure, that is, the upper part of each component when the toothbrush is placed vertically. The main body 11 generally includes a housing 13, a cover body 18 and a mounting structure 16 disposed in the housing 13. The housing 13 defines a accommodating space. A motor 14 and a battery 15 for providing power to the motor 14 are disposed in the accommodating space. In order to facilitate the installation of the motor and the battery, a mounting structure 16 is disposed in the housing, and the mounting structure 16 is used to install the motor 14 and the battery 15. The mounting structure 16 includes an upper shell 161 and a lower shell 162. Reference Figure 6 , the upper shell 161 is arranged at the first end (upper end or output shaft end) of the motor 14, and a first shock-absorbing pad 111 is arranged between the upper shell 161 and the outer shell 13. In one embodiment, the shape of the first shock-absorbing pad 111 matches the top of the upper shell 161, and the cover is arranged at the end of the upper shell 161. The first shock-absorbing pad 111 is provided with a through hole for the motor shaft to pass through, and the motor shaft and the through hole are interference fit, and the shock-absorbing pad also plays a waterproof role. Of course, in other embodiments, the first shock-absorbing pad 111 can also be other shapes, or a shock-absorbing structure composed of several shock-absorbing sheets. A second shock-absorbing pad 112 is arranged between the motor 14 and the upper shell 161. The second shock-absorbing pad 112 is arranged at the upper end of the motor 14, and the second shock-absorbing pad 112 includes a horizontal shock-absorbing section and a vertical shock-absorbing section, and the horizontal shock-absorbing section and the vertical shock-absorbing section are both in contact with the inner wall of the upper shell 161. Reference Fig.11 and Fig.13 , the lower shell 162 defines a first space 163 and a second space 164. The second end of the motor 14 is arranged at the first space 163, and a third shock-absorbing pad 113 is arranged between the second end of the motor 14 and the lower shell 162. At least part of the battery 15 is arranged in the second space 164. The lower shell 162 is provided with a snap-on structure 165, and the snap-on structure 165 is configured so that after the lower shell 162 is installed in the accommodation space, the snap-on structure 165 and the shell 13 are in contact to limit the lower shell 162 from moving outward along the axial direction relative to the shell 13. Through the fixed relationship between the upper shell 161, the motor 14, the lower shell 162 and the shell 13, the motor 14 and the battery 15 can be placed together on the mounting structure 16, and then the mounting structure 16 can be installed in the shell 13, and the lower shell 162 can be kept in the accommodation space through the shell 13. In this way, it is convenient to install and the shock-absorbing performance of the motor 14 can be improved.

[0039] refer to Figure 9-14 , with special reference Fig.10The clamping structure 165 can be a protruding structure symmetrically arranged on both sides of the lower shell 162. The protruding structure contacts the step structure arranged inside the shell 13. The step structure supports the protruding structure, which can effectively ensure that the mounting structure 16 is stably installed in the accommodation space without the need for other fixing structures to fix the mounting structure 16. During installation, the worker only needs to apply a little force, and the protruding structure moves in the shell 13 until it moves to the top of the step structure. At this time, the lower end of the protruding structure abuts against the upper surface of the step structure to limit the mounting structure 16.

[0040] In order to ensure that the upper housing 161 and the motor 14 are tightly connected, the upper housing 161 and the motor 14 are fixed together by fasteners. A shock absorbing structure can also be provided at the fastener to further reduce vibration. In this embodiment, the fastener is a bolt. Of course, in other structures, other structures can also be used.

[0041] A circuit board 17 is also mounted on the mounting structure 16, and the circuit board 17 is mounted on the upper housing 161 and / or the lower housing 162. A card joint structure may be provided on the upper housing 161 or the lower housing 162, and the circuit board 17 is carded onto the mounting structure 16, and then installed into the housing 13 together with the mounting structure 16. A light strip is also provided on the circuit board 17, and various functional information can be displayed through different display lights. The circuit board 17 extends along the axial direction of the housing 13, and the height of the circuit board 17 is substantially the same as the height of the mounting structure 16.

[0042] refer to Figure 8 The cover 18 is used to close the accommodation space. When the mounting structure is installed in the accommodation space, the accommodation space is sealed by the cover. The cover 18 is generally arranged at the lower end of the main body 11. The cover 18 is provided with a limiting column 181. The limiting column 181 is used to limit the movement of the battery 15 along the axial direction of the shell.

[0043] refer to Figure 3 and Figure 4 In order to realize the overall positioning of the mounting structure 16, a positioning structure 19 is provided between the upper shell 161 and the lower shell 162. The positioning structure 19 is configured to complete the circumferential positioning between the upper shell 161 and the lower shell 162 before the mounting structure 16 is installed in the accommodation space. In this way, it can ensure that the mounting structure 16 is smoothly installed in the accommodation space, facilitate operation, and save installation time.

[0044] refer to Figure 3 and 4In a specific embodiment, the positioning structure 19 includes a slot 191 provided on the upper shell 161 or the lower shell 162, and the lower shell 162 or the upper shell 161 is provided with a hook 192. After the mounting structure 16 is assembled to the housing 13, the hook 192 and the slot 191 do not contact each other. When the entire electric toothbrush 1 is installed, in order to avoid noise between the hook 192 and the slot 191, they are designed not to contact each other.

[0045] refer to Fig.12 and 13 The lower housing 162 includes a fastening structure 20, which is configured to hold the battery 15 in the second space 164. The lower housing 162 includes a hollow surface for dissipating heat for the battery 15. The fastening structure 20 includes one or more pressing sheets, which can press the battery 15. In order to further fix the battery 15 in the lower housing 162, a limiting column 181 is further provided on the cover 18. When the cover 18 is installed on the housing 13, the limiting column 181 contacts the lower end of the battery 15 to prevent the battery 15 from moving up and down.

[0046] Although the implementation scheme of the utility model has been disclosed as above, it is not limited to the applications listed in the specification and implementation scheme. It can be fully applied to various fields suitable for the utility model. For those familiar with the art, additional modifications can be easily implemented. Therefore, without departing from the general concept defined by the claims and the scope of equivalents, the utility model is not limited to the specific details and the illustrations shown and described here.
