[0022] The present utility model provides an oral cleaning device 100. The oral cleaning device 100 involved in the present utility model can be either an electric toothbrush or a dental irrigator. In this embodiment, the oral cleaning device 100 is taken as an example of an electric toothbrush for description. The oral cleaning device 100 includes a working member 10 and a handle member 20 which are combined with each other. The handle member 20 includes a housing 21, a control assembly 22, a power source and a motor. The motor and the control assembly 22 are respectively electrically connected to the power source, and at least a part of the control assembly 22 is arranged on the housing 21.

In this embodiment, the second control assembly 24 is set as the stepless adjustment assembly, and the second control assembly 24 is electrically connected to the power source. The second control assembly 24 is used for the user to perform stepless adjustment on the oral cleaning device. Specifically, the user can manipulate the second control assembly 24 to change the vibration amplitude of the motor, and further change the operating parameters of the oral cleaning device 100. When the oral cleaning device 100 is an electric toothbrush, the operating parameters refer to the vibration amplitude or vibration frequency of the electric toothbrush head. When the oral cleaning device 100 is a dental irrigator, the operating parameters refer to the impact pressure or impact frequency of the pulsed water flow of the dental irrigator.

[0023] Further, the second control assembly 24 includes a second operation key 241 and a sliding rheostat 242. The sliding rheostat 242 is electrically connected to the power source, and the second operation key triggers the sliding rheostat to change the resistance value through magnetic force.

An inner screen 25 is arranged between the second operation key 241 and the sliding rheostat 242. An indicator light 251 is arranged on the inner screen 25, and the indicator light 251 is exposed through the housing 21. And the indicator light 251 is signal-connected to the second control assembly 24. When the user adjusts the second control assembly 24 to change the motor amplitude, the indicator light 251 changes the lighting signal to display the operating parameters of the oral cleaning device 100.

[0024] A bracket 26 is provided in the outer shell 21, the sliding rheostat 242 is mounted on the bracket 26, a control board 27 is further provided between the inner screen 25 and the bracket 26, the control board 27 is electrically connected to the power supply and is in signal connection with the indicator light 251 on the inner screen 25.

Then, when the user slides the second operation key 241 along the sliding groove 30, by using the magnetic attraction force generated between the driving magnet 243 and the driven magnet 244, the sliding piece 245 moves along with the sliding of the second operation key 241, the resistance value of the sliding rheostat 242 changes, thereby causing the change of the current intensity, and finally changing the amplitude or vibration frequency of the motor.

[0025] The first control component 23 is set as the start / stop key of the oral cleaning device 100, and the first control component 23 protrudes from the circumferential surface of the outer shell 21. The first control component 23 includes a first operation key 231 and a signal element 271 provided on the control board 27, and the signal element 271 is in signal connection with the power supply. A touch key 230 is provided on the first operation key 231, and the touch key 230 is used to trigger the signal element 271. When the oral cleaning device 100 is not powered on, press the first operation key 231 to make the touch key 230 touch the signal element 271, and the signal element 271 emits a power-on signal, and the oral cleaning device 100 is powered on; when the oral cleaning device 100 is powered on, press the first operation key 231 to make the touch key 230 touch the signal element 271 again, and the oral cleaning device 100 is powered off.

[0026] Further, the first control component 23 can also be set as a hierarchical adjustment component. At this time, the signal element 271 has a first gear member 2711, a second gear member 2712 and a third gear member 2713. The first gear member 2711, the second gear member 2712 and the third gear member 2713 are all in signal connection with the power supply respectively, and different gears control the oral cleaning device 100 to operate at different motor amplitudes. The user can rotate the first operation key 231 to the corresponding gear and press to turn on the oral cleaning device 100 to make it operate in the corresponding gear mode. At the same time, the first control component 23 is also provided with an anti-touch gear. Specifically, a stop element 28 is provided on the control board 27, and the stop element 28 is not in signal connection with the power supply. When the first operation key 231 touches the stop element 28, the state of the oral cleaning device 100 remains unchanged. That is, when the user rotates the first operation key 231 to the anti-collision gear corresponding to the stop element 28, even if the first operation key 231 is touched by an external force, causing the touch key 230 to touch the stop element 23, the oral cleaning device 100 cannot be powered on or off.

[0027] In other embodiments, a trigger is provided on the first operation key 231, a triggered member is provided on the inner screen 25, and at least one signal element 271 is provided on the control board 27.

Specifically, the triggered member is provided as a fifth magnet 291. The fifth magnet 291 has the same magnetic polarity (magnetic poles repel) as the first magnet 2311 and the third magnet 2313, that is, the fifth magnet 291 has the opposite magnetic property (magnetic poles attract) to the second magnet 2312 and the fourth magnet 2314. When the user rotates the first operation key 231 so that the first magnet 2311 or the third magnet 2313 corresponds to the fifth magnet 291 in the direction perpendicular to the longitudinal direction, and the user presses the first operation key 231, since the first magnet 2311 / third magnet 2313 and the fifth magnet 291 repel each other magnetically, under the repulsive force of the first magnet 2311, the fifth magnet 291 moves and touches the signal element 271, thereby turning on the oral cleaning device 100. When the user rotates the first operation key 231 so that the second magnet 2312 or the fourth magnet 2314 corresponds to the fifth magnet 291 in the direction perpendicular to the longitudinal direction, since the second magnet 2312 / fourth magnet 2314 and the fifth magnet 291 attract each other magnetically, under the magnetic attraction force, the fifth magnet 291 is attracted to the second magnet 2312 or the fourth magnet 2314. At this time, even if the first operation key 231 is touched by an external force, the fifth magnet 291 cannot touch the signal element 271 to cause the oral cleaning device 100 to turn on or off. In other embodiments, the fifth magnet 291 may also have the same magnetic polarity (magnetic poles repel) as the second magnet and the fourth magnet.
