[0048] Figure 3 Show Figure 2 A partial enlarged view of the structure marked as A; Figure 4 A partial structural schematic diagram of an oral cleaning device provided in Embodiment 1 of the present invention is shown (the housing is not shown). Figure 3 and Figure 4 The oral cleaning device includes a device body 100, a switch assembly 200 and a driving assembly 400. The driving assembly 400 is disposed in the device body 100 and can drive the device body 100 to vibrate. The switch assembly 200 includes a movable assembly 210, a pressing assembly 220 and a magnetic field sensing module 230. The movable assembly 210 is magnetic and is rotatably disposed on the outside of the device body 100. The pressing assembly 220 is located on the inner side of the device body 100 and is spaced apart from the movable assembly 210. The movable assembly 210 can press the pressing assembly 220 through a part of the device body 100 to control the start and stop of the driving assembly 400. The magnetic field sensing module 230 is disposed in the device body 100 and is non-contactly disposed with the movable component 210, and can receive the magnetic field information of the movable component 210. The movable component 210 can rotate relative to the magnetic field sensing module 230 to change the magnetic field information received by the magnetic field sensing module 230, and the driving component 400 can adjust the rotation speed according to the magnetic field information. By utilizing the cooperation of the magnetic movable component 210 and the magnetic field sensing module 230 and utilizing the Hall effect, the function of the non-contact switch is realized. By the arrangement of the non-contact switch, it is possible to avoid the operation of opening a passage on the device body 100 in order to set the switch component 200, and the integrity and sealing performance of the structure of the device body 100 can be ensured, and the problem of water inside the device body 100 caused by poor sealing at the switch component 200 position can be prevented.
[0049] Specifically, the device body 100 includes a housing 110, the driving assembly 400 is disposed in the housing 110, the housing 110 is recessed from the circumference toward the central axis to form a mounting groove, and the movable assembly 210 is rotatably embedded in the mounting groove.
[0050] More specifically, the oral cleaning device further includes a control mainboard 300. The control mainboard 300 is disposed in the housing 110, and the magnetic field sensing module 230, the driving assembly 400 and the pressing assembly 220 are respectively connected to the control mainboard 300.
[0051] More specifically, the pressing component 220 is located below the mounting groove in the pressing direction, and the position of the housing 110 corresponding to the mounting groove is elastic, and the bottom of the mounting groove can be pressed against the pressing component 220 under the drive of the movable component 210 moving in the pressing direction to start or stop the driving component 400. In this embodiment, the position of the housing 110 corresponding to the mounting groove is made of elastic soft rubber material to provide the possibility for the bottom of the mounting groove to move in the pressing direction.
[0052] As an alternative, Figure 5 Show Figure 4 A partial enlarged view of the structure marked as B; Figure 6 FIG. 1 is a partial structural diagram of a switch assembly provided in Embodiment 1 of the present invention. Figure 5 and Figure 6 The control main board 300 is provided with an avoidance hole 310 at the position of the installation groove, and the avoidance hole 310 can prevent the control main board 300 from interfering with the bottom position of the installation groove. The pressing component 220 is located inside the avoidance hole 310, and the outer side of the bottom of the installation groove can partially extend into the avoidance hole 310 and contact the pressing component 220. Through the above arrangement, the stroke of the movable component 210 applying pressure to the pressing component 220 in the pressing direction can be shortened, thereby reducing the pressure that the user needs to apply when starting or stopping the driving component 400, thereby improving the user's experience.
[0053] More specifically, the device body 100 further includes a brush head 120. The brush head 120 is disposed at one end of the housing 110 and connected to the drive assembly 400, and can vibrate under the drive of the drive assembly 400 to improve the cleaning effect.

[0054] More specifically, the oral cleaning device further comprises a battery 500. The battery 500 is disposed inside the housing 110 and is electrically connected to the control mainboard 300, so as to provide power to the driving assembly 400 and the magnetic field sensing module 230, etc.
[0055] Continue to refer to Figure 3 and Figure 6, the pressing component 220 includes a pressure sensor 221, an electrical connection plate 222 and a force feedback device (not shown). The pressure sensor 221 is located below the movable component 210 in the pressing direction, and is connected to the control main board 300 through the electrical connection plate 222, and is communicatively connected to the driving component 400. The movable component 210 can trigger a pressure signal by applying pressure to the pressure sensor 221, and the driving component 400 can be started or shut down according to the pressure signal of the pressure sensor 221.

The magnetic member 212 is disposed in the movable housing 211, and can rotate in the mounting groove relative to the magnetic field sensing module 230 to change the magnetic field between the magnetic member 212 and the magnetic field sensing module 230. When the magnetic field between the magnetic member 212 and the magnetic field sensing module 230 changes, the intensity of the magnetic field at the location sensed by the magnetic field sensing module 230 can be changed, thereby controlling the conduction or disconnection of the circuit inside the magnetic field sensing module 230 according to the Hall effect, thereby realizing the control of the rotation speed of the driving assembly 400.
[0057] Specifically, the magnetic field sensing module 230 includes a plurality of magnetic field sensing members 231, which are arranged at intervals to form a receiving space, and the movable component 210 is located in the receiving space.

Figure 3 , Figure 5 and Figure 6 The movable housing 211 is spherical in structure and can be movably embedded in the mounting groove and can rotate around its own spherical center. The movable housing 211 partially protrudes from the peripheral side of the housing 110, which is convenient for users to perform pressing or rolling operations.
[0059] Embodiment 2
[0060] This embodiment provides an oral cleaning device. The only difference between this embodiment and the first embodiment is the shape of the movable shell 211 and the movement of the movable shell 211 in the installation groove in order to change the magnetic field between the magnetic field sensing module 230 and the magnetic member 212.
[0061] In this embodiment, the movable shell 211 is a roller structure, and a rotating shaft (not shown) is arranged in the installation groove. The movable shell 211 can rotate around the rotating shaft, and at the same time can drive the outer shell 110 to move in the pressing direction to the position corresponding to the bottom of the installation groove, so that it can realize the pressing effect on the pressing component 220.
[0062] Specifically, the rotating shaft may be parallel to the extension direction of the oral cleaning device, or may be perpendicular to the extension direction of the oral cleaning device, depending on whether the portion of the movable housing 211 protruding from the housing 110 is convenient for the user to press and roll. In this embodiment, the rotating shaft is perpendicular to the extension direction of the oral cleaning device, that is, the user can push and roll the movable housing 211 in the extension direction of the oral cleaning device to achieve a change in the magnetic field between the magnetic field sensing module 230 and the magnetic member 212.
