[0024] The utility model is now further described in conjunction with the accompanying drawings and specific implementation methods.

[0025] Reference Figures 1 to 4 As shown, the electric toothbrush with voice function provided in this embodiment includes a handle part 10 and a brush head part 20. The handle part 10 includes a handle shell 11, an inner bracket 12, a battery 15, a motor 14, a control circuit board 13, a speaker 16 and a plug assembly 17. The handle shell 11 has a mounting cavity and a front plug and a rear opening connected to the mounting cavity. The battery 15, the motor 14 and the control circuit board 13 are all mounted on the inner bracket 12 and are mounted together in the mounting cavity of the handle shell 11. The setting of the inner bracket 12 can form a stable support for the battery 15, the motor 14 and the control circuit board 13, which is not easy to be misplaced. As in this embodiment, the motor 14 is located at the front end of the battery 15, and the control circuit board 13 is located at the side end of the battery 15.

[0026] The motor shaft 141 of the motor 14 passes through the front socket, and the brush head part 20 is detachably inserted on the motor shaft 141. The rear section of the inner bracket 12 also isolates a space to form a front sound cavity 101; the speaker 16 is assembled on the plug assembly 17, and the plug assembly 17 is assembled on the rear opening of the brush handle shell 11. The plug assembly 17 forms a rear sound cavity 102, and the front sound cavity 101 and the rear sound cavity 102 are respectively located on the front and rear sides of the speaker 16; the control circuit board 13 connects the motor 14 and the speaker 16 to control the operation of the motor 14 and the speaker 16, and the battery 15 supplies power to the motor 14, the control circuit board 13 and the speaker 16.

[0027] Specifically, the battery 15, motor 14 and control circuit board 13 are all assembled on the inner bracket 12, which can form a stable support for the battery 15, motor 14 and control circuit board 13, and the front sound cavity 101 is directly formed by the space isolated by the rear section of the inner bracket 12. During assembly and use, the front sound cavity 101 will not be filled due to the misalignment of the above-mentioned components; the plug assembly 17 forms a rear sound cavity 102, and the front sound cavity 101 and the rear sound cavity 102 are respectively located on the front and rear sides of the speaker 16. In this way, the sound emitted by the speaker 16 can be amplified in the front sound cavity 101 and the rear sound cavity 102 at the same time, and the sound is fuller and the pronunciation effect is good, thereby greatly improving the user experience.

[0028] Specifically, the plug assembly 17 abuts against the rear end of the inner bracket 12, and can abut and fix the inner bracket 12, so as to better maintain the position of each component and prevent it from loosening. The rear end of the inner bracket 12 is provided with a sound hole 124 connected to the front sound cavity 101, and the sound hole 124 is arranged corresponding to the speaker 16, and the sound emitted from the front end of the speaker 16 is transmitted to the front sound cavity 101 through the sound hole 124.

[0029] Furthermore, the rear section of the inner bracket 12 includes a central axis 122 connected to the bracket body and a rear end plate 121 connected to the central axis 122. The rear end plate 121 serves as the rear end of the inner bracket 12. The plug assembly 17 abuts against the rear end plate 121. The sound holes 124 are also provided on the rear end plate 121. Specifically, a plurality of sound holes 124 are provided and distributed in a circle along the periphery of the central axis 122. The bracket body, the central axis 122, the rear end plate 121 and the inner wall of the brush handle housing 11 are enclosed together to form the front sound cavity 101. The central axis 122 has a hollow cavity 123 connected to the front sound cavity 101. In this way, the space of the front sound cavity 101 is increased as much as possible, and the setting of the hollow cavity 123 of the central axis 122 enables sound waves to be reflected back and forth in the hollow cavity 123, thereby achieving better sound amplification.

[0030] Specifically, the plug assembly 17 includes a plug 171 and a mounting tube 172, the mounting tube 172 is sleeved in the plug 171, the speaker 16 is mounted at the front end of the mounting tube 172, the rear end space of the mounting tube 172 is the rear sound cavity 102, and the plug 171 is provided with a sound outlet 173 connected to the rear sound cavity 102. The installation tube 172 is provided to simultaneously assemble the speaker 16 and form the rear sound cavity 102, and the plug 171 is used to block the rear opening of the brush handle housing 11 to achieve assembly.

[0031] The battery 15 is a rechargeable battery, and the charging method is wireless charging. The implementation structure is: the brush handle part 10 also includes a charging coil 19, and the charging coil 19 is assembled on the plug assembly 17. The charging coil 19 is connected to the battery 15 to charge the battery 15. Specifically, the charging coil 19 is clamped between the plug 171 and the mounting tube 172 to form a stable assembly. The charging coil 19 also has a clearance window to allow sound waves to pass through.

[0032] Furthermore, in this embodiment, the handle portion 10 further includes a display screen 18, which is connected to the control circuit board 13; the display screen 18 is disposed in the handle housing 11 and is fixed to the inner bracket 12, specifically, is located at the front end of the control circuit board 13, so as to achieve unified assembly. A display window corresponding to the display screen 18 is provided on the handle housing 11. The display screen 18 can be provided so that the user can intuitively confirm the selected information, such as the gear position information of the electric toothbrush.

[0033] At the same time, since the diameter of the handle housing 11 of the toothbrush is small, the display window cannot be made very large. In order to facilitate viewing, in this embodiment, a convex lens sheet 181 is also sealed in the display window of the handle housing 11. The convex lens sheet 181 can well magnify the font of the display screen 18, making it easier for the user to see clearly. At the same time, the convex lens sheet 181 is sealed in the display window, which can play a good isolation role.

[0034] Furthermore, the handle housing 11 is provided with an abutting protrusion 182 on the inner side of the display window, and the convex lens sheet 181 abuts against the abutting protrusion 182 . The abutting protrusion 182 can abut and limit the convex lens sheet 181 to ensure that the convex lens sheet 181 is assembled in place.

[0035] The handle housing 11 is also provided with a button 131 , such as a start button or a gear shift button, etc. The button 131 acts on the control circuit board 13 to operate the electric toothbrush.

[0036] Specifically, in this embodiment, the specific structures and connection structures of the above-mentioned battery 15, motor 14, control circuit board 13, speaker 16, charging coil 19, display screen 18 and button 131 are all existing technologies, which have been mastered and applied by technicians in this field long ago, and will not be described in detail here.

[0037] The electric toothbrush with voice function provided in this embodiment is one of the more preferred implementations in the present application. Of course, it is not limited to this in other embodiments. For example, the plug assembly can also be set as an independent component, and a charging interface can also be set on the brush handle shell for charging the battery in a wired manner, or the display screen structure is not used, or voice interaction is used to achieve human-computer interaction, etc.

[0038] Although the present invention has been specifically demonstrated and described in conjunction with the preferred embodiments, those skilled in the art should understand that various changes may be made to the present invention in form and detail without departing from the spirit and scope of the present invention as defined in the appended claims, all of which are within the scope of protection of the present invention.
