Description

Technical Field

[0001] This application belongs to the field of cleaning equipment technology, and specifically provides a control method for a surface cleaning system. Background Technology

[0002] As people's living standards improve, a variety of electric surface cleaning devices are gradually entering people's daily lives, greatly facilitating the cleaning of house floors. Some electric surface cleaning devices are also equipped with a washing station to self-clean their mop parts, thereby reducing the cleaning work for users.

[0003] Currently, surface cleaning devices are equipped with operation buttons for activating the cleaning mode and the self-cleaning mode. When a user uses the surface cleaning device to clean the surface, they need to press the cleaning mode operation button to activate the device. When the surface cleaning device is in self-cleaning mode, the user needs to press the self-cleaning mode operation button to activate it. The operation is relatively complicated, and it is easy to press the wrong button, resulting in a poor user experience. Summary of the Invention

The surface cleaning system includes a surface cleaning device and a cleaning seat. The surface cleaning device includes a user input control element, a controller, and a cleaning module. The controller is electrically connected to both the user input control element and the cleaning module. The controller includes a cleaning mode and a self-cleaning mode. The control method includes:

[0005] The controller receives input information from the user and obtains the docking status between the surface cleaning device and the cleaning seat;

[0006] If the surface cleaning device and the cleaning seat are in a docked state, the self-cleaning mode will be activated.

[0016] Optionally, the aforementioned control method further includes:

[0017] During the aforementioned self-cleaning mode, the aforementioned power supply circuit charges the aforementioned rechargeable battery pack; or,

[0018] After the aforementioned self-cleaning mode ends, the aforementioned power supply circuit charges the aforementioned rechargeable battery pack.

[0019] Optionally, when the charge of the aforementioned rechargeable battery pack reaches a preset buffer value, the charging speed of the aforementioned power supply circuit for the aforementioned rechargeable battery pack is slowed down.

[0020] Optionally, the aforementioned surface cleaning device is equipped with a detection element, and the aforementioned cleaning seat is equipped with a trigger element. After the aforementioned surface cleaning device and the aforementioned cleaning seat are properly aligned, the aforementioned detection element is triggered by the aforementioned trigger element to generate a detection signal.

[0021] "Obtaining the docking status of the surface cleaning device and the cleaning seat" includes:

[0022] If the aforementioned controller receives a detection signal from the aforementioned detection element, it determines that the surface cleaning device and the cleaning seat are in a docked state; otherwise, it determines that the surface cleaning device and the cleaning seat are in a non-docked state; or...

[0023] The aforementioned surface cleaning device is equipped with a current sensor. When the aforementioned surface cleaning device is electrically connected to the aforementioned cleaning seat, current flows through the aforementioned current sensor, causing the current sensor to emit a detection signal.

[0024] "Obtaining the docking status of the surface cleaning device and the cleaning seat" includes:

[0025] If the controller receives the detection signal from the current sensor, it determines that the surface cleaning device and the cleaning seat are in a docked state; otherwise, it determines that the surface cleaning device and the cleaning seat are in a non-docked state.

[0026] Optionally, the aforementioned self-cleaning modes include:

[0027] When the rechargeable battery pack's charge level is lower than the first charge level, the power supply circuit supplies power to the aforementioned delivery pump, roller brush motor, and vacuum motor to drive the surface cleaning device to perform self-cleaning.

[0028] Optionally, the aforementioned self-cleaning modes include:

[0029] When the charge level of the aforementioned rechargeable battery pack is higher than the first charge level but lower than the second charge level, the aforementioned rechargeable battery pack supplies power to one of the aforementioned delivery pump and roller brush motor, and the aforementioned power supply circuit supplies power to the other of the aforementioned delivery pump and roller brush motor and to the aforementioned vacuum motor; and / or

[0030] When the charge level of the aforementioned rechargeable battery pack is higher than the aforementioned second charge level, the aforementioned rechargeable battery pack supplies power to the aforementioned delivery pump, roller brush motor and vacuum motor.

[0031] Optionally, the following steps are included before activating the self-cleaning mode:

[0032] Determine whether the handle of the surface cleaning device is in an upright position. If the handle is in an upright position, activate the self-cleaning mode.

[0033] Those skilled in the art will understand that the control method of the surface cleaning system described above in this application has at least the following beneficial effects:

[0034] 1. By enabling the controller to acquire the docking status of the surface cleaning device, the user input control can be used to start the cleaning mode when the surface cleaning device and the cleaning seat are not docked, and can be used to start the self-cleaning mode when the surface cleaning device and the cleaning seat are docked. This allows the user to control the start of the cleaning mode and the self-cleaning mode with a single user input control, eliminating the need to select different control devices for different situations. This simplifies the operation and avoids situations where pressing the wrong control device causes the surface cleaning device to fail to start.

[0035] Furthermore, by obtaining the dirt status of the cleaning roller before starting the self-cleaning mode, the self-cleaning mode can be started when the cleaning roller is dirty, which can avoid resource waste and prevent over-cleaning from shortening the service life of the cleaning roller.

[0036] 2. By using a power supply circuit and a rechargeable battery pack to supply power to at least one of the conveying pump, roller brush motor, and vacuum motor to enable the surface cleaning device to perform self-cleaning, the power supply mode can be changed according to the power level of the rechargeable battery pack. Specifically, when the power level of the rechargeable battery pack is lower than a first power level, the power supply circuit supplies power to the conveying pump, roller brush motor, and vacuum motor to avoid over-discharge of the rechargeable battery pack, thereby avoiding a reduction in the service life of the rechargeable battery pack.

[0037] When the rechargeable battery pack has a charge level higher than a first charge level but lower than a second charge level, the rechargeable battery pack supplies power to one of the delivery pump and the roller brush motor. The power supply circuit supplies power to the other of the delivery pump and the roller brush motor and also supplies power to the vacuum motor. This reduces the load on the rechargeable battery pack when the charge level is low, and avoids poor cleaning performance due to low voltage supplied by the rechargeable battery pack.

[0038] When the rechargeable battery pack has a charge level higher than the second charge level, it supplies power to the delivery pump, roller brush motor, and vacuum motor, thereby ensuring the normal operation of the rechargeable battery pack and the cleaning effect of the surface cleaning device.

[0039] 3. By charging the rechargeable battery pack during the self-cleaning mode, the self-cleaning of the cleaning roller and the charging of the rechargeable battery pack occur simultaneously. This ensures that the rechargeable battery pack has sufficient charge after the surface cleaning device completes its self-cleaning process, facilitating subsequent cleaning and improving cleaning efficiency. Alternatively, by charging the rechargeable battery pack after the self-cleaning mode has ended, the need for simultaneous charging and use of the rechargeable battery pack can be avoided, making it more battery-friendly. Alternatively, it can prevent excessive load on the power supply circuit, thus extending its lifespan. Attached Figure Description

Those skilled in the art should understand that, provided the technical solution described in this application can be implemented, any changes in the composition, implementation, and positional relationship of the functional modules will not deviate from the technical principles of this application, and therefore should all fall within the protection scope of this application.

[0051] Furthermore, it should be noted that, in the description of this application, unless otherwise expressly specified and limited, the terms "installation," "connection," and "linkage" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can also refer to the internal connection of two components. Those skilled in the art can understand the specific meaning of the above terms in this application according to the specific circumstances.

[0052] The surface cleaning system of this application includes a surface cleaning device and a cleaning base. The surface cleaning device includes a user input control component, a controller, and a cleaning module. The controller is electrically connected to both the user input control component and the cleaning module. The controller includes a cleaning mode and a self-cleaning mode. The control method of this application includes:

[0053] The controller receives input information from the user and obtains the docking status between the surface cleaning device and the cleaning seat;

[0054] If the surface cleaning device and the cleaning seat are in a docked state, the self-cleaning mode will be activated.

[0055] If the surface cleaning device and the cleaning seat are not in a docked state, start the cleaning mode.

[0056] This application enables the controller to acquire the docking status of the surface cleaning device, allowing the user input control to activate the cleaning mode when the surface cleaning device and the cleaning seat are not docked, and to activate the self-cleaning mode when the surface cleaning device and the cleaning seat are docked. This allows the user to control the activation of both the cleaning and self-cleaning modes using a single user input control, eliminating the need to select different control devices for different situations. This simplifies the operation and avoids situations where pressing the wrong control device causes the surface cleaning device to fail to activate.

[0057] The control method of the surface cleaning system of this application will be described in detail below with reference to the accompanying drawings and specific embodiments.

[0058] The first embodiment of this application:

[0059] like Figures 1 to 3As shown, the surface cleaning system of this application includes a surface cleaning device 1 and a cleaning seat 2. The surface cleaning device 1 includes a cleaning head 11, a body 12, a handle 13, and a cleaning module 14. The cleaning module includes a cleaning roller 141, a roller brush motor 142, a sludge collection tank 143, a vacuum motor 144, a delivery pump 145, and a clean water tank 146. The cleaning roller 141 is rotatably mounted on the cleaning head 11, and the roller brush motor 142 is used to drive the cleaning roller 141 to rotate. The cleaning head 11 is provided with a dust suction port 111. The sludge collection tank 143 is mounted on the body 12 and is connected to the vacuum motor 144 and the dust suction port 111 respectively. The suction force generated by the vacuum motor 144 can suck dirt into the sludge collection tank 143 through the dust suction port 111. The clean water tank 146 is set on the body 12, and the delivery pump 145 is used to supply the cleaning liquid in the clean water tank 146 to the cleaning roller 141. The handle 13 is equipped with a user input control element 131, and the surface cleaning device 1 is equipped with a controller 15. The controller 15 is electrically connected to the user input control element 131 and the cleaning module 14 (specifically, the electrical components in the cleaning module 14). The user can control the opening and closing of the cleaning module 14 by operating the user input control element 131. The surface cleaning device 1 is equipped with a rechargeable battery pack 16 and a power supply circuit 17. The cleaning base 2 can be connected to mains power through a power adapter. The surface cleaning device 1 can be electrically connected to the cleaning base 2 and use the power supply circuit 17 to charge the rechargeable battery pack 16.

[0060] Combined Figure 4 As shown, the control method in this embodiment includes:

[0061] Step S101: Controller 15 receives input information from user input control unit 131.

[0062] The user input control element 131 can be a button. After the user presses the user input control element 131, the controller 15 receives the input information from the user input control element 131.

[0063] It should be noted that the user control component 131 can also be an operation key with various operation methods such as tossing or pushing.

[0064] Step S102: The controller 15 determines whether the surface cleaning device 1 and the cleaning seat 2 are in a docking state. If they are not docked, proceed to step S103; if they are docked, proceed to step S104.

[0065] As an example: The surface cleaning device 1 is equipped with a detection element, and the cleaning seat 2 is equipped with a trigger element. The detection element and the trigger element are set in corresponding positions. After the surface cleaning device 1 and the cleaning seat 2 are docked, the trigger element on the cleaning seat 2 approaches the detection element on the surface cleaning device 1, so that the detection element generates a detection signal under the action of the trigger element. The controller 15 obtains the docking status of the surface cleaning device 1 and the cleaning seat 2 by obtaining the detection signal.

[0066] The detection element and trigger element can be a reed switch and a magnet. After the surface cleaning device 1 and the cleaning seat 2 are in place, the reed switch is turned on by the magnet to generate a detection signal. Alternatively, the detection element and trigger element can be a magnetic sensor and a magnet. After the surface cleaning device 1 and the cleaning seat 2 are in place, the magnetic sensor detects the magnetic field of the magnet to generate a detection signal.

[0067] As an example 2: The surface cleaning device 1 is equipped with a current sensor. After the surface cleaning device 1 and the cleaning seat 2 are docked and an electrical connection is formed, the current sensor detects the current and generates a detection signal.

[0068] As an example three: The surface cleaning device 1 is equipped with a switch, and the cleaning seat 2 is equipped with a top column. After the surface cleaning device 1 and the cleaning seat 2 are properly connected, the top column on the cleaning seat 2 presses against the switch on the surface cleaning device 1 to turn on the switch, thereby generating a detection signal.

[0069] Step S103: Start the cleaning mode.

[0070] Specifically, when the controller 15 does not receive a detection signal, it determines that the surface cleaning device 1 and the cleaning seat 2 are in a non-dating state, thereby activating the cleaning mode. At this time, the controller 15 connects the circuit between the rechargeable battery pack 16 and the cleaning module 14, thereby enabling the rechargeable battery pack 16 to supply power to the roller brush motor 142, the vacuum motor 144 and the delivery pump 145. The roller brush motor 142 drives the cleaning roller 141 to rotate, and the rotating cleaning roller 141 cleans the surface to be cleaned. The vacuum motor 144 generates suction at the dust inlet 111, sucking the dirt on the surface to be cleaned into the dirt collection bucket 143. The delivery pump 145 supplies the cleaning liquid in the clean water tank 146 to the cleaning roller 141 to assist the cleaning roller 141 in cleaning the surface to be cleaned.

[0071] Step S104: Determine whether the handle 13 is in an upright position. If it is in an upright position, proceed to step S105.

[0072] Specifically, when the controller 15 receives a detection signal, it determines that the surface cleaning device 1 and the cleaning seat 2 are in a docking state, that is, the surface cleaning device 1 and the cleaning seat 2 have been docked in place. Then, the controller 15 obtains whether the handle 13 is in an upright state:

[0073] Because the handle 13 and the body 12 move together, in other words, it determines whether the handle 13 and the body 12 are in an upright state. Specifically, the pivot connection between the body 12 and the cleaning head 11 is provided with a triggering component and a detection component. The triggering component on the body 12 can be in different positions as the body 12 rotates. When the body 12 and the handle 13 are not in an upright state, the triggering component on the body 12 is far away from the detection component at the cleaning head 11, so it cannot generate a detection signal. When the body 12 and the handle 13 rotate from an upright state to an upright state, the triggering component at the pivot of the body 12 moves closer to the detection component on the cleaning head 11 as the body 12 rotates. When the body 12 reaches the upright state, the triggering component triggers the detection component, thereby transmitting a signal to the controller 15 to determine that the surface cleaning device 1 is in an upright state.

[0074] It should be noted that the triggering component and the detection component can adopt the triggering element and detection element described in step S102 above. Alternatively, the triggering component can also be set on the cleaning head 11, while the detection component is set on the body 12.

[0075] It should also be noted that the upright state referred to in this embodiment is only a description of the state in which the handle 13 and the body 12 are naturally placed. Depending on the production process, the upright state can be vertical or it can be at a certain tilt angle.

[0076] Those skilled in the art will understand that by determining whether the handle 13 is in an upright state before activating the self-cleaning mode, it can be ensured that the surface cleaning device 1 is in a natural placement state after being placed on the cleaning seat 2, that is, the state with the most stable center of gravity. This is beneficial to the stability of the surface cleaning device 1 on the cleaning seat 2 and avoids the vibration generated when the self-cleaning mode is activated from affecting the placement of the surface cleaning device 1.

[0077] Additionally, although not shown in the figure, if it is determined in this step that the surface cleaning device 1 is not in an upright state, a prompt may be issued, or the surface cleaning device 1 may not perform any work, and the user may see that the self-cleaning has not been activated and move the handle 13 of the surface cleaning device 1 on their own.

[0078] Step S105: Determine whether the cleaning roller 141 is dirty. If the cleaning roller 141 is dirty, proceed to step S106.

[0079] Specifically, when the controller 15 receives a signal that the handle 13 is in an upright position, the controller 15 obtains the dirt status of the cleaning roller 141:

[0080] As an example: The surface cleaning device 1 is equipped with a program recording module to record the mode activation status of the surface cleaning device 1. That is, when the surface cleaning device 1 activates the cleaning mode, the program recording module records the first information and overwrites the previous recorded information. When the surface cleaning device 1 activates the self-cleaning mode, the program recording module records the second information and overwrites the previous recorded information. When the surface cleaning device 1 is properly connected to the cleaning seat 2 and the user presses the user input control 131, the controller 15 receives the information signal from the program recording module. When the controller 15 receives the signal of the first information (i.e., the cleaning mode was activated last time), it determines that the cleaning roller 141 is dirty.

[0081] As an example 2: The surface cleaning device 1 is equipped with an image acquisition module, which is used to acquire surface images of the cleaning roller 141, determine the dirt status of the cleaning roller 141 based on the image analysis results, and transmit a signal to the controller 15 when the cleaning roller 141 is dirty.

[0082] Those skilled in the art will understand that by obtaining the dirt status of the cleaning roller 141 before activating the self-cleaning mode, the self-cleaning mode can be activated when the cleaning roller 141 is dirty, thus avoiding resource waste and preventing over-cleaning from shortening the service life of the cleaning roller 141.

[0083] It should be noted that, although not shown in the figure, if it is determined in this step that the surface cleaning device 1 is not dirty, a prompt may be issued, or the surface cleaning device 1 may not perform any work. That is to say, the surface cleaning device 1 is simply placed on the cleaning seat 2.

[0084] Step S106: Start the self-cleaning mode.

[0085] Specifically, after receiving a signal that the cleaning roller 141 is dirty, the controller 15 activates the self-cleaning mode, supplying power to the roller brush motor 142, vacuum motor 144, and delivery pump 145 via the rechargeable battery pack 16 and / or power supply circuit 17. The roller brush motor 142 drives the cleaning roller 141 to rotate on the cleaning seat 2, and the delivery pump 145 supplies cleaning fluid from the clean water tank 146 to the cleaning roller 141, enabling the cleaning roller 141 to self-clean. The vacuum motor 144 generates suction at the suction port 111, drawing the wastewater generated during cleaning into the collection bucket 143.

[0086] It should be noted that the roller brush motor 142, vacuum motor 144 and conveying pump 145 can work simultaneously, or they can be set to perform cleaning and suction in stages in a cycle.

[0087] Furthermore, the surface cleaning device 1 is equipped with a power detection module for detecting the power level of the rechargeable battery pack. In self-cleaning mode, the controller 15 controls the power supply method of the power supply circuit 17 and the rechargeable battery pack 16 to the cleaning module 14 based on the power signal fed back by the power detection module.

[0088] When the charge of the rechargeable battery pack 16 is lower than the first charge value, the power supply circuit 17 supplies power to the roller brush motor 142, the vacuum motor 144 and the delivery pump 145 to drive the surface cleaning device to perform self-cleaning. This means that the rechargeable battery pack 16 is in an idle state when the charge is low, so as to avoid the rechargeable battery pack 16 being over-discharged and thus avoid reducing the service life of the rechargeable battery pack 16.

[0089] When the charge level of the rechargeable battery pack 16 is higher than the first charge level but lower than the second charge level, the rechargeable battery pack supplies power to one of the delivery pump 145 and the roller brush motor 142, and the power supply circuit 17 supplies power to the other of the delivery pump 145 and the roller brush motor 142 and supplies power to the vacuum motor 144, thereby reducing the load on the rechargeable battery pack 16 when the charge level of the rechargeable battery pack 16 is insufficient, and avoiding poor cleaning effect due to low voltage supplied by the rechargeable battery pack 16;

[0090] When the charge level of the rechargeable battery pack 16 is higher than the second charge level, the rechargeable battery pack 16 supplies power to the delivery pump 145, the roller brush motor 142 and the vacuum motor 144.

[0091] It should be noted that the first battery level can be 10%, 15%, 20%, etc., of the total battery level, and the second battery level can be 50%, 60%, 70%, etc., of the total battery level.

[0092] Step S107: During the self-cleaning mode, the power supply circuit 17 charges the rechargeable battery pack 16.

[0093] Specifically, once the surface cleaning device 1 and the cleaning seat 2 are properly connected, an electrical connection is formed between them. The power supply circuit 17 can then charge the rechargeable battery pack 16. Furthermore, the self-cleaning mode of the surface cleaning device 1 can be activated simultaneously during charging. In other words, the power supply circuit 17 can charge the rechargeable battery pack 16 independently; it is not necessary for the self-cleaning mode to be activated before charging can occur. Both processes can simply occur concurrently.

[0094] Those skilled in the art will understand that by enabling the power supply circuit 17 to charge the rechargeable battery pack 16 during the self-cleaning mode, i.e., the self-cleaning of the cleaning roller 141 and the charging of the rechargeable battery pack 16 are carried out simultaneously, the rechargeable battery pack 16 has sufficient power after the surface cleaning device 1 completes the self-cleaning, which facilitates subsequent cleaning work and improves cleaning efficiency.

[0095] Preferably, when the charge level of the rechargeable battery pack 16 reaches a preset buffer value, the charging speed of the power supply circuit 17 on the rechargeable battery pack 16 is slowed down to prevent overcharging and overheating of the rechargeable battery pack 16, thereby avoiding damage to the rechargeable battery pack 16. The preset buffer value can be any value such as 80%, 85%, or 90% of the total charge level.

[0096] In summary, those skilled in the art will understand that this embodiment can control the cleaning mode and the self-cleaning mode through a single user input control 131. In other words, the user only needs to operate one user input control 16, eliminating the need to select different controls for different situations, thus simplifying the operation and preventing the surface cleaning device 1 from failing to start due to pressing the wrong control. Furthermore, by obtaining the dirt status of the cleaning roller 141 before activating the self-cleaning mode, the self-cleaning mode can be activated when the cleaning roller 141 is relatively dirty, avoiding resource waste and preventing over-cleaning that could shorten the service life of the cleaning roller 141.

[0097] Furthermore, the power supply method of the rechargeable battery pack 16 and the power supply circuit 17 to the cleaning module 14 during self-cleaning is determined based on the power level of the rechargeable battery pack 16. The power supply circuit 17 charges the rechargeable battery pack 16 simultaneously with self-cleaning. When the power level of the rechargeable battery pack 16 is very low, it is kept idle while the power supply circuit 17 charges it, preventing over-discharge and thus avoiding a reduction in its lifespan. When the power level of the rechargeable battery pack 16 is insufficient, the load on it is reduced to prevent poor cleaning performance of the cleaning roller 141 due to low voltage supplied by the rechargeable battery pack 16. In addition, this method ensures that the rechargeable battery pack 16 has sufficient power after the surface cleaning device 1 completes self-cleaning, facilitating subsequent cleaning operations and improving cleaning efficiency.

[0098] The second embodiment of this application:

[0099] like Figure 5 As shown, unlike the first embodiment, the control method in this embodiment includes:

[0100] Step S201: The controller receives input information from the user input control unit.

[0101] Step S202: The controller checks whether the surface cleaning device and the cleaning seat are in a docked state. If they are not docked, proceed to step S203; if they are docked, proceed to step S204.

[0102] Step S203: Start the cleaning mode.

[0103] Step S204: Start the self-cleaning mode.

[0104] Step S205: During the self-cleaning mode, the power supply circuit charges the rechargeable battery pack.

[0105] In other words, this embodiment does not include steps for determining whether the handle is in an upright position or for detecting the dirt status of the cleaning roller.

[0106] It should be noted that this embodiment may also retain one of the two steps: determining whether the handle is in an upright state and detecting the dirt status of the cleaning roller.

[0107] The third embodiment of this application:

[0108] Although not shown in the figure, unlike the first embodiment, in this embodiment, the steps of obtaining the docking status of the surface cleaning device and the cleaning seat, determining whether the handle is in an upright state, and determining whether the cleaning roller is dirty are performed simultaneously, rather than sequentially. That is, the judgments are made simultaneously, and the self-cleaning mode is activated when all three signals are received at the same time.

[0109] The fourth embodiment of this application:

[0110] Although not shown in the figure, this embodiment differs from the first embodiment in that the order of steps for obtaining the docking state of the surface cleaning device and the cleaning seat, determining whether the handle is in an upright state, and determining whether the cleaning roller is dirty is different. The steps in this embodiment are as follows:

[0111] Step 1: Determine if the handle is in an upright position. If yes, proceed to Step 2; otherwise, proceed to Step 5.

[0112] Step 2: Check if the surface cleaning device and the cleaning seat are in a docked state. If yes, proceed to Step 3; otherwise, do not perform any work.

[0113] Step 3: Check if the cleaning roller is dirty. If so, proceed to Step 4.

[0114] Step 4: Activate self-cleaning mode.

[0115] Step 5: Check if the surface cleaning device and the cleaning seat are in a docked state. If yes, do not perform any work; if not, proceed to step 6.

[0116] Step 6: Start the cleaning mode.

[0117] The fifth embodiment of this application:

[0118] Although not shown in the figure, unlike the previous embodiment, in this embodiment, instead of "the power supply circuit charging the rechargeable battery pack during the self-cleaning mode", the power supply circuit charges the rechargeable battery pack after the self-cleaning mode ends. Specifically, during the self-cleaning process of the surface cleaning device, the charging circuit of the power supply circuit to the rechargeable battery pack is disconnected. Only after the surface cleaning device completes the self-cleaning does the power supply circuit start charging the rechargeable battery pack. Furthermore, the power supply circuit automatically starts charging the rechargeable battery pack after the self-cleaning process ends.

[0119] Those skilled in the art will understand that by having the power supply circuit charge the rechargeable battery pack after the self-cleaning mode ends, it is possible to avoid the rechargeable battery pack being used while being charged, which is more friendly to the rechargeable battery pack. It is also possible to avoid the power supply circuit from charging the rechargeable battery pack and supplying power to the cleaning mode at the same time, which would result in too much load and affect the service life of the power supply circuit.

[0120] The technical solutions of this application have been described in conjunction with the preceding embodiments. However, it will be readily understood by those skilled in the art that the scope of protection of this application is not limited to these specific embodiments. Without departing from the technical principles of this application, those skilled in the art can disassemble and combine the technical solutions in the above embodiments, and can also make equivalent changes or substitutions to the relevant technical features. Any changes, equivalent substitutions, improvements, etc., made within the technical concept and / or technical principles of this application will fall within the scope of protection of this application.
