Detailed implementation manners

[0033] The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present invention without creative efforts shall fall within the protection scope of the present invention.

[0034] <First embodiment>

[0035] A cleaning device in this embodiment is applied to cleaning dirt attached to a movable cleaning head of a handheld beauty care device. Refer to Figure 1 , in this embodiment, the handheld beauty care device is an electric shaver 200, the movable cleaning head is the cutter head of the electric shaver 200, and the cleaning device correspondingly is a shaver washer 100. A "beauty care device" refers to a beauty or care device.

[0036] The shaver washer 100 includes a base 10, a wireless communication device, and a controller.

[0037] The base 10 has a receiving groove 11, and the receiving groove 11 is at least for the cutter head of the electric shaver 200 to be placed in. A cleaning part is arranged on the base 10 for cleaning dirt attached to the cutter head.

[0038] Specifically, the cleaning part is a cleaning liquid supply part. After the cutter head of the electric shaver 200 is placed in the receiving groove 11 of the base 10, the cleaning part continuously flushes the dirt in the cutter head of the electric shaver 200 with the pumped cleaning liquid to achieve cleaning.

[0039] During the above cleaning process, since some dirt adheres stubbornly to the cutter head and is difficult to be directly washed away, when the cleaning unit is started, the cutter head needs to be controlled to perform actions such as vibration to further make the attached dirt fall off, so as to achieve a better cleaning effect.

[0040] In this embodiment, a wireless communication device and a controller are provided to cooperate for signal transmission, so as to respond to the start of the cleaning unit and send an instruction to the electric shaver 200 to start the action of the cutter head via the wireless communication device.

[0041] Specifically, the wireless communication device is arranged in the base 10 of the cleaning device. The base 10 has a convex portion 12 which protrudes from the top of the base 10 in a manner higher than the notch of the receiving groove 11, and the wireless communication device is arranged in the convex portion 12. The wireless communication device includes an electromagnet 20 and a control circuit for controlling the magnitude of the current of the electromagnet. The control circuit generates an instruction based on the change of the current of the electromagnet 20.

[0042] The controller is arranged in the electric shaver 200 and includes a Hall sensor 30 and a circuit board. The Hall sensor 30 is arranged inside the main body of the electric shaver 200.

[0043] Specifically, the shaver 200 includes a handle, the circuit board is arranged inside the housing of the handle, and the Hall sensor 30 is arranged on one side of the circuit board close to the housing of the handle.

[0044] In this embodiment, by arranging the electromagnet 20 in the convex portion 12 of the base 10, after the electric shaver 200 is placed into the receiving groove 11 of the base 10, the Hall sensor 30 and the electromagnet 20 can be axially aligned to ensure the maximum coupling of the magnetic field vectors. At the same time, the Hall sensor 30 is arranged on one side of the circuit board close to the housing of the handle to ensure the distance between the Hall sensor 30 and the electromagnet 20, thereby ensuring the magnetic field coupling efficiency and enabling the signal to be accurately and stably transmitted.

[0045] Furthermore, the controller is communicatively connected to both the wireless communication device and the cleaning unit. The controller is configured to: in response to the start of the cleaning unit, send an instruction to the electric shaver 200 to start the action of the cutter head via the wireless communication device, so that the shaver washer 100 and the electric shaver 200 form a cleaning kit.

[0046] In this embodiment, the electromagnet 20 and the Hall sensor 30 in the wireless communication device cooperate with each other, and the electromagnet 20 transmits signals unidirectionally to the Hall sensor 30, so that the cutter head responds to the start of the cleaning part to perform actions. Specifically, the control circuit conducts or cuts off the current flowing through the electromagnet according to a preset rule based on the instruction to be sent. The electromagnet 20 will have a magnetic field change according to the change of the flowing current. The Hall sensor 30 uses the Hall effect to convert the magnetic field change into a voltage change signal. The circuit board of the controller decodes the voltage change signal to obtain the corresponding instruction, and controls the cutter head to perform corresponding actions according to the instruction.

[0047] In this embodiment, non-contact signal transmission between the shaver cleaner 100 and the electric shaver 200 is carried out through the cooperation of the electromagnet 20 and the Hall sensor 30, which can achieve low-power and high-reliability communication between devices on the premise of ensuring complete physical isolation, and at the same time has the significant advantages of controllable cost and easy engineering implementation.

[0048] Furthermore, a cleaning method in this embodiment is used to clean the dirt attached to the cutter head of the shaver 200, and includes the following steps:

[0049] Place the cutter head of the shaver 200 into the receiving groove 11 of the shaver cleaner 100.

[0050] In response to the start of cleaning the cutter head, the shaver cleaner 100 sends an instruction to the shaver 200 in a wireless communication manner to start the action of the cutter head of the shaver 200.

[0051] Specifically, the shaver cleaner 100 is provided with a wireless communication device, including an electromagnet 20 and a control circuit for controlling the magnitude of the current of the electromagnet 20. The shaver 200 is provided with a controller, including a Hall sensor 30 and a circuit board for decoding according to the voltage change of the Hall sensor 30 to obtain an instruction.

[0052] When the cutter head of the shaver 200 is placed into the receiving groove 11 of the shaver cleaner 100 and the cleaning part is started, in response to the start of cleaning the cutter head, the control circuit of the wireless communication device makes the magnetic field generated by the electromagnet 20 change correspondingly by controlling the magnitude of the current passing through the electromagnet 20 according to the to-be-sent cutter head vibration instruction. The Hall sensor 30 of the controller receives the magnetic field change and generates a corresponding voltage change signal. The circuit board decodes according to the voltage change signal to obtain the corresponding cutter head vibration instruction, and controls the cutter head to vibrate according to the cutter head vibration instruction, so that the dirt attached to the cutter head falls off, achieving a better cleaning effect.

[0053] <Second Embodiment>

[0054] A cleaning device in this embodiment is applied to cleaning the dirt attached to the movable cleaning head of a handheld beauty care device. Refer toFigure 2 In this embodiment, the handheld beauty care device is an electric toothbrush 400, the movable cleaning head is the brush head of the electric toothbrush 400, and the cleaning device correspondingly is the ultraviolet disinfection storage box 300.

[0055] The ultraviolet disinfection storage box 300 includes a base 10, a wireless communication device, and a controller.

[0056] The base 10 has a receiving groove 11, and the receiving groove is at least for the brush head of the electric toothbrush 400 to be placed in. The cleaning part is arranged on the base 10 and is used for cleaning the dirt attached to the brush head.

[0057] In this embodiment, the cleaning part is an ultraviolet disinfection lamp. The whole electric toothbrush 400 is placed in the receiving groove 11, and the brush head is correspondingly placed at the irradiation position of the ultraviolet disinfection lamp. The ultraviolet disinfection lamp irradiates the brush head with ultraviolet rays to perform sterilization and disinfection to achieve cleaning.

[0058] During the above cleaning process, due to the limited irradiation angle of the ultraviolet disinfection lamp, and the dirt such as moisture or toothpaste foam that may remain on the brush head blocking the ultraviolet irradiation, it is difficult to comprehensively and deeply sterilize and disinfect the brush head. When the cleaning part is started, it is necessary to control the brush head to perform actions such as rotation and vibration, so that the ultraviolet rays can irradiate the brush head from all angles and irradiate the brush head deeply, so as to achieve a better cleaning effect.

[0059] In this embodiment, by setting up a wireless communication device and a controller to cooperate for signal transmission, in response to the start of the cleaning part, an instruction to start the action of the brush head is sent to the electric toothbrush 400 via the wireless communication device.

[0060] Specifically, the wireless communication device is arranged in the base 10 of the cleaning device. The wireless communication device includes an electromagnet 20 and a control circuit for controlling the magnitude of the current of the electromagnet 20. The control circuit generates an instruction based on the change of the current of the electromagnet 20.

[0061] The controller is arranged in the electric toothbrush 400 and includes a Hall sensor 30 and a circuit board. The Hall sensor 30 is arranged inside the main body of the electric toothbrush 400.

[0062] Specifically, the electric toothbrush 400 includes a handle. The circuit board is arranged inside the housing of the handle, and the Hall sensor 30 is arranged on one side of the circuit board close to the housing of the handle.

[0063] In this embodiment, after the electric toothbrush 400 is placed in the receiving groove 11 of the base 10, the Hall sensor 30 and the electromagnet 20 will be axially aligned, and the Hall sensor 30 is arranged on one side of the circuit board close to the housing of the handle to ensure the distance between the Hall sensor 30 and the electromagnet 20, and further ensure the magnetic field coupling efficiency.

[0064] Further, the controller is communicatively connected to both the wireless communication device and the cleaning unit. The controller is configured to: in response to the startup of the cleaning unit, send an instruction to the electric toothbrush 400 to start the action of the brush head via the wireless communication device, so that the ultraviolet disinfection storage box 300 and the electric toothbrush 400 form a cleaning kit.

[0065] In this embodiment, the electromagnet 20 and the Hall sensor 30 in the wireless communication device cooperate with each other. The electromagnet 20 unidirectionally transmits signals to the Hall sensor 30, so that the brush head moves in response to the startup of the cleaning unit. Specifically, the control circuit conducts or cuts off the current flowing through the electromagnet according to a preset rule based on the instruction to be sent. The electromagnet 20 will change the magnetic field according to the change of the flowing current. The Hall sensor 30 uses the Hall effect to convert the magnetic field change into a voltage change signal. The circuit board of the controller decodes the voltage change signal to obtain the corresponding instruction, and controls the brush head to perform the corresponding action according to the instruction.

[0066] In this embodiment, the electromagnet 20 and the Hall sensor 30 are used to cooperate for non-contact signal transmission between the ultraviolet disinfection storage box 300 and the electric toothbrush 400, which can achieve low-power and high-reliability communication between devices on the premise of ensuring complete physical isolation, and at the same time has the significant advantages of controllable cost and easy engineering implementation.

[0067] Further, a cleaning method of this embodiment is used to clean the dirt attached to the brush head of the electric toothbrush 400, and includes the following steps:

[0068] Place the brush head of the electric toothbrush 400 into the receiving groove 11 of the ultraviolet disinfection storage box 300.

[0069] In response to the startup of the cleaning of the brush head, the ultraviolet disinfection storage box 300 sends an instruction to the electric toothbrush 400 in a wireless communication manner to start the action of the brush head of the electric toothbrush 400.

[0070] Specifically, the ultraviolet disinfection storage box 300 is provided with a wireless communication device, including an electromagnet 20 and a control circuit for controlling the magnitude of the current of the electromagnet 20. The electric toothbrush 400 is provided with a controller, including a Hall sensor 30 and a circuit board for decoding according to the voltage change of the Hall sensor 30 to obtain an instruction.

[0071] When the brush head of the electric toothbrush 400 is placed in the receiving groove 11 of the ultraviolet disinfection storage box 300 and the cleaning unit is started, in response to the start of cleaning the brush head, the control circuit of the wireless communication device makes the magnetic field generated by the electromagnet 20 change correspondingly by controlling the magnitude of the current passing through the electromagnet 20 according to the brush head vibration instruction or the brush head rotation instruction to be sent. The Hall sensor 30 of the controller receives the magnetic field change and generates a corresponding voltage change signal. The circuit board decodes the voltage change signal to obtain the corresponding brush head vibration instruction or brush head rotation instruction, and controls the brush head to vibrate or rotate according to the brush head vibration instruction or the brush head rotation instruction. The vibration of the brush head promotes the fall of dirt such as residual moisture or toothpaste foam in the brush head, reduces the shielding of ultraviolet rays, and further performs more effective deep sterilization and disinfection on the brush head. At the same time, the rotation of the brush head enables the brush head to receive ultraviolet irradiation at all angles for sterilization and disinfection, achieving a more comprehensive cleaning effect.

[0072] The above are only the preferred embodiments of the present invention and are not intended to limit the present invention. Any modifications, equivalent replacements, and improvements made within the spirit and principles of the present invention shall be included in the protection scope of the present invention.
