[0039] Many specific details are described in the following description to facilitate a full understanding of this specification. However, this specification can be implemented in many other ways than those described herein, and those skilled in the art can make similar generalizations without violating the connotation of this specification, so this specification is not limited to the specific implementation disclosed below.

[0041] It should be understood that although the terms first, second, etc. may be used to describe various information in one or more embodiments of this specification, this information should not be limited to these terms. These terms are only used to distinguish the same type of information from each other. For example, without departing from the scope of one or more embodiments of this specification, the first may also be referred to as the second, and similarly, the second may also be referred to as the first. Depending on the context, the word "if" as used herein may be interpreted as "at the time of" or "when" or "in response to determining".

[0042] It should be noted that with people's increasing demand for cleaning quality, traditional cleaning tools have gradually faded out of people's sight. A large number of cleaning equipment such as vacuum cleaners, sweepers, and floor scrubbers have entered users' homes. After years of development, cleaning equipment has shown a trend of automation, functionality, diversification, and specialization, and the cleaning scenes of cleaning equipment have also increased. In order to meet people's needs to reduce the number of times they dump dust buckets, cleaning equipment base station-type products have emerged. When the cleaning equipment is placed in the base station, the base station detects and sends a self-cleaning signal to the cleaning equipment, and the cleaning equipment and the base station begin to perform self-cleaning operations.

[0043] In the prior art, a high level is sent from the base station to the charging port of the cleaning device, so that the battery pack enters the charging state, and then a pulse signal corresponding to the self-cleaning signal is sent. The cleaning device detects the pulse signal corresponding to the self-cleaning signal, and then sends a charge-to-discharge instruction to the battery pack, and the battery pack is converted from the charging state to the discharging state, and then the cleaning device as a whole executes the self-cleaning command. However, when the cleaning device is fully charged on the base station and enters the dormant state, the capacitor on the activation circuit is in a fully charged state and cannot be activated based on the high level sent by the charging port of the base station, and the control unit of the cleaning device enters a low power consumption state and cannot receive other activation signals to activate the battery pack, resulting in the battery pack being unable to activate and unable to respond to the self-cleaning signal, which in turn causes the cleaning device to be unable to perform self-cleaning.

[0044] During implementation, a high level can often be sent to the charging port of the cleaning equipment through the base station to put the battery pack into a charging state, and then a pulse signal corresponding to the self-cleaning signal is sent. The cleaning equipment detects the pulse signal corresponding to the self-cleaning signal, and then sends a charge-to-discharge instruction to the battery pack. The battery pack is converted from a charging state to a discharging state, and then the cleaning equipment as a whole executes the self-cleaning command.

[0045] Figure 1 Schematic diagram of a voltage signal of a self-cleaning control process provided by an embodiment of this specification, taking a vacuum cleaner as an example, Figure 1 As shown, the voltage signal of the base station charging port is: high 3s-30s square wave-high; the voltage signal of the vacuum cleaner charging switch is normally high, that is, the vacuum cleaner charging switch is continuously in the on state; the battery pack charging voltage is consistent with the voltage signal of the base station charging port.

[0046] However, when the cleaning device is fully charged on the base station and enters a dormant state, the capacitor on the activation circuit is in a fully charged state and cannot be activated based on the high level sent by the base station charging port, and the control unit of the cleaning device enters a low power consumption state and cannot receive other activation signals to activate the battery pack, resulting in the battery pack being unable to activate and unable to respond to the self-cleaning signal, which in turn causes the cleaning device to be unable to self-clean. Therefore, a self-cleaning control system for a cleaning device is provided in an embodiment of the present specification. By controlling the change of the voltage signal output by the base station charging port and the switching timing of the charging switch on the cleaning device, the capacitor on the battery pack activation circuit can be discharged first and then the battery pack can be activated, solving the problem that the cleaning device cannot self-clean after being fully charged on the base station and entering a dormant state, so that the cleaning device can start the self-cleaning operation, ensuring that the cleaning device can self-clean.

[0047] In this specification, a self-cleaning control system of a cleaning device is provided. This specification also relates to a self-cleaning control method of a cleaning device, a computing device, and a computer-readable storage medium, which are described in detail one by one in the following embodiments.

[0048] Figure 2 This is a structural block diagram of a self-cleaning control system for a cleaning device provided in an embodiment of this specification, such as Figure 2 As shown, the self-cleaning control system includes a cleaning device 202 and a base station 204, the cleaning device 202 includes a device control unit 2021, a charging terminal 2022 and a battery pack 2023, the base station 204 includes a base station control unit 2041 and a base station charging port 2042, the charging terminal 2022 of the cleaning device is connected to the base station charging port 2042 of the base station, and the cleaning device 202 is in a dormant state;

[0049] The base station control unit 2041 is configured to control the base station charging port 2042 to output a low level voltage signal first and then a high level voltage signal when a self-cleaning instruction is detected;

[0050] The device control unit 2021 is configured to detect that the base station charging port 2042 outputs a low-level voltage signal, control the charging switch on the cleaning device to turn off and then turn on the charging switch to activate the battery pack 2023 of the cleaning device 202 and start the self-cleaning operation of the cleaning device 202, wherein the charging switch is used to control the charging status of the charging terminal 2022, and when the charging switch is turned on, the base station charging port 2042 outputs a high-level voltage signal.

[0051] Specifically, Figure 2 As shown, the base station 204 includes a base station control unit 2041 connected to a base station charging port 2042 to control a voltage signal of the base station charging port 2042 ; and a device control unit 2021 connected to a charging terminal 2022 to detect a voltage signal of the base station charging port 2042 .

[0052] Cleaning equipment refers to the intelligent device body that performs cleaning tasks, such as vacuum cleaners, sweepers, floor scrubbers, etc.; base station refers to a workstation corresponding to the cleaning equipment and used to perform auxiliary work of the cleaning equipment, such as powering the cleaning equipment, performing self-cleaning of the cleaning equipment, and other auxiliary work.

[0053] It should be noted that the cleaning equipment corresponds to the base station. After use, the cleaning equipment can be put back into the base station. The base station includes a base station charging port. The base station charging port can charge the battery pack of the cleaning equipment through the charging switch. That is, when the charging switch is turned on, the base station charging port charges the battery pack through the charging end. When the charging switch is turned off, the base station charging port stops charging the battery pack. The cleaning equipment can enter a sleep state after being fully charged.

[0054] For example, Figure 3a Schematic diagram of a cleaning device provided in an embodiment of the present specification without being placed in a base station, such as Figure 3a As shown, the cleaning device corresponds to the base station, and the cleaning device is not placed in the base station. Figure 3b This is a schematic diagram of a cleaning device placed in a base station according to an embodiment of this specification. Figure 3b As shown, the cleaning device corresponds to the base station, and the cleaning device is placed in the base station, and the base station is connected to a power source to supply power to the cleaning device.

[0055] In addition, the cleaning device is provided with a device control unit for controlling the cleaning device, and the device control unit may be an MCU (Micro Control Unit) provided on the cleaning device; the base station is provided with a base station control unit for controlling the base station, and the base station control unit may be an MCU provided on the base station.

[0056] In actual implementation, after the cleaning device is put back into the base station, the self-cleaning instruction can be triggered. At this time, the cleaning device has not entered the sleep state, and the battery pack does not need to be activated. The base station control unit can control the base station charging port to output a high level for a set period of time to make the battery pack enter the charging state, and then send a pulse signal corresponding to the self-cleaning signal. The device control unit of the cleaning device detects the pulse signal corresponding to the self-cleaning signal, and then sends a charge-to-discharge instruction to the battery pack. The battery pack is converted from the charging state to the discharging state, and the cleaning device as a whole performs the self-cleaning operation.

[0057] Among them, before the cleaning device enters the sleep state, the self-cleaning instruction can be automatically triggered by the base station control unit, or it can be triggered by the user through the interactive control provided by the base station, and the interactive control can be a physical button or a virtual button on a touch screen, etc.; the self-cleaning signal can also be triggered by the interactive control provided on the cleaning device, and the interactive control can be a physical button set on the cleaning device or a virtual button on a touch screen, etc., and the embodiments of this specification do not limit this.

[0058] In actual applications, the cleaning equipment will enter a sleep state after being fully charged. The capacitor of the activation circuit on the cleaning equipment is in a fully charged state and cannot be activated based on the high level sent by the base station charging port. The control unit of the cleaning equipment enters a low power consumption state and can only respond to the voltage change signal of the base station charging port. It cannot receive other activation signals to activate the battery pack.

[0059] Therefore, in the embodiment of this specification, when the cleaning device is placed on the base station and is in a dormant state, if the base station control unit detects a self-cleaning instruction, the base station charging port can be controlled to output a low-level voltage signal first and then a high-level voltage signal, that is, the level of the base station charging port is first lowered and then raised. Since the base station charging port is in a normally high state before the self-cleaning instruction is detected, the level of the base station charging port will change from high to low and then to high. In specific implementation, controlling the base station charging port to output a low-level voltage signal is to control the base station charging port to be closed, and the level of the base station charging port is pulled low; controlling the base station charging port to output a high-level voltage signal is to open the base station charging port, and the level of the base station charging port is pulled high.

[0060] Among them, the low-level voltage signal is the voltage when the base station charging port is closed, and the high-level voltage signal is the voltage when the base station charging port is opened.

[0061] In addition, when the equipment control unit detects that the charging port of the base station outputs a low-level voltage signal, it means that the charging port of the base station changes from an open state to a closed state. At this time, it can be determined that activation is required to respond to the self-cleaning instruction, so the charging switch on the cleaning device is controlled to be closed. After the charging switch is turned off, the capacitor of the activation circuit on the cleaning device is discharged. The time when the charging switch is turned off is the discharge time of the capacitor. Then the charging switch is turned on again. When the charging switch is turned on again, the output of the charging port of the base station is a high-level voltage signal. The high-level voltage signal can activate the battery pack of the cleaning device to power the cleaning device, so that the cleaning device can start the self-cleaning operation. Among them, the cleaning device starts the self-cleaning operation, which means that the cleaning device executes the self-cleaning program on the cleaning device side. In addition, the self-cleaning program can also involve the base station side. The base station can execute the self-cleaning program on the base station side to cooperate in self-cleaning the cleaning device.

[0062] It should be noted that after the cleaning device enters the sleep state, the change in voltage signal from high to low can be detected by the device detection unit by controlling the charging port of the base station to change from a high-level voltage signal to first output a low-level voltage signal and then output a high-level voltage signal, so as to control the closing of the charging switch, thereby ensuring the discharge time of the capacitor in the battery pack activation circuit. Then the device control unit can also receive a high-level voltage signal to activate the battery pack. In other words, by controlling the change in the voltage signal output by the base station charging port and the switching timing of the charging switch on the cleaning device, the capacitor in the battery pack activation circuit can be discharged first and then the battery pack can be activated, which solves the problem that the battery pack cannot be activated after the cleaning device is fully charged on the base station and enters the sleep state, resulting in the inability to self-clean. The cleaning device can respond to the self-cleaning instruction and start the self-cleaning operation of the cleaning device, thereby ensuring that the cleaning device can perform self-cleaning.

[0063] In an optional implementation of this embodiment, the base station control unit 2041 is further configured as follows:

[0064] Control the base station charging port 2042 to output a low-level voltage signal of a first duration;

[0065] After the first duration is reached, the base station charging port 2042 is controlled to output a high-level voltage signal of a second duration, wherein the second duration is greater than the first duration.

[0066] Specifically, the first duration and the second duration can be pre-configured based on actual business needs, the first duration is the duration of lowering the base station charging port, and the second duration is the duration of raising the base station charging port.

[0067] During implementation, the first time length needs to ensure that the device control unit can detect the low-level voltage signal. However, if the first time length is too long, the cleaning device will have a black screen for a long time. Therefore, the first time length of the device is generally smaller, such as the first time length can be set to 1s; the second time length needs to be set greater than the first time length to ensure that the output of the base station charging port is a high-level voltage signal when the charging switch is turned on. For example, the second time length can be set to 4s.

[0068] It should be noted that, when the base station control unit detects a self-cleaning instruction, it can first control the base station charging port to output a low-level voltage signal for a first duration, and then control the base station charging port to output a high-level voltage signal for a second duration after reaching the first duration. That is, the base station charging port is first lowered for a first duration, and then raised for a second duration. For example, the base station control unit can control the base station charging port to be lowered for 1 second and then raised for 4 seconds.

[0069] In the embodiments of the present specification, the charging port of the base station can be controlled to output a low-level voltage signal of a first duration first, so as to provide a sufficient duration for the device control unit to detect the low-level voltage signal, thereby ensuring that the device control unit can detect the low-level voltage signal output by the charging port of the base station; in addition, after reaching the first duration, the charging port of the base station can be controlled to output a high-level voltage signal of a second duration, wherein the second duration is greater than the first duration, thereby providing sufficient time for activating the battery pack on the cleaning device, thereby ensuring that the battery pack can be successfully activated, thereby improving the success rate of the battery pack activation, and thereby ensuring the response rate of the self-cleaning instruction.

[0070] In an optional implementation of this embodiment, the device control unit 2021 is further configured as follows:

[0071] Determining whether a low-level voltage signal lasting a third duration is detected, wherein the third duration is less than or equal to the first duration;

[0072] If so, turn off the charging switch on the cleaning device, and turn on the charging switch after a fourth time period to activate the battery pack 2023 of the cleaning device and start the self-cleaning operation of the cleaning device, wherein the fourth time period is less than the second time period.

[0073] Specifically, the third time duration and the fourth time duration may also be pre-configured based on actual business needs, the third time duration being the time duration for detecting a low-level voltage signal, and the fourth time duration being the time duration for turning off a charging switch on the cleaning device.

[0074] In actual implementation, the duration of the low-level voltage signal output by the base station charging port is the first duration, and thus the device control unit can only detect a low-level voltage signal of the first duration at most, that is, the third duration is less than or equal to the first duration. In order to avoid missing the low voltage level signal and causing insufficient detection duration, the third duration can generally be set to be less than the first duration, such as 300ms.

[0075] In addition, the fourth time length is the time length for closing the charging switch on the cleaning device, that is, the discharge time of the capacitor of the activation circuit on the cleaning device, and the fourth time length can be set based on the actual capacitor discharge time. In addition, it is necessary to ensure that the base station charging port outputs a high-level voltage signal when the charging switch is turned on again, so the second time length is related to the fourth time length, and the fourth time length needs to be less than the second time length. For example, when the second time length is 4s, the fourth time length is 3s, so that it can be ensured that when the charging switch is turned on again, the output of the base station charging port is a high-level voltage signal.

[0076] It should be noted that the device control unit can determine whether a low-level voltage signal lasting for the third time period is detected. If so, it means that the current base station charging port outputs a low-level voltage signal, that is, the current base station charging port is closed. At this time, the charging switch on the cleaning device can be turned off to allow the capacitor of the activation circuit on the cleaning device to discharge, and then the charging switch can be turned on again after the fourth time period, so that the device control unit can receive the high-level voltage signal output by the base station charging port to activate the battery pack of the cleaning device and start the self-cleaning operation of the cleaning device.

[0077] In the embodiment of the present specification, the device control unit determines that the current base station charging port outputs a low-level voltage signal only when it detects a low-level voltage signal that lasts for a third period of time, and controls the charging switch on the cleaning device to close, thereby avoiding misjudgment, thereby avoiding false activation of the battery pack, and improving the accuracy of battery pack activation; in addition, when a low-level voltage signal that lasts for a third period of time is detected, it indicates that self-cleaning is currently required, that is, the battery pack needs to be activated. Since the cleaning device will enter a dormant state after being fully charged, the capacitor of the activation circuit on the cleaning device is in a fully charged state, and therefore the charging switch on the cleaning device can be closed to provide time for the capacitor to discharge, thereby ensuring that the battery pack can be activated, thereby ensuring that after entering the dormant state, it can respond to the self-cleaning instruction and start the self-cleaning operation of the cleaning device.

[0078] In an optional implementation of this embodiment, the second duration and the fourth duration are set based on the activation duration of the battery pack, and the difference between the fourth duration and the second duration is the activation duration of the battery pack.

[0079] It should be noted that the difference between the fourth time duration and the second time duration is the activation time duration of the battery pack, and thus the second time duration and the fourth time duration may be set based on the activation time duration of the battery pack.

[0080] In addition, in actual implementation, the charging port of the base station outputs a low-level signal of the first duration, and the device control unit only needs to detect the low-level voltage signal of the third duration to control the closing of the charging switch for the fourth duration. Within the time difference between the first duration and the third duration, the cleaning device can also receive a high-level voltage signal, and thus can also provide more time than the time difference between the fourth duration and the second duration for battery pack activation. That is to say, the time difference between the fourth duration and the second duration is the minimum time that the cleaning device can receive a high-level voltage signal, that is, the minimum time for battery pack activation.

[0081] For example, the fourth duration is 3s and the second duration is 4s, that is, the base station charging port outputs a high level for 4s, the charging switch of the cleaning device is closed for 3s, that is, 3s is used for capacitor discharge, and then the charging switch of the cleaning device is turned on. At this time, the cleaning device has at least 1s to receive the high-level voltage signal output by the base station charging port. If the first duration is 1s and the third duration is 300ms, the cleaning device has 1700ms to receive the high-level voltage signal output by the base station charging port for battery pack activation.

[0082] In the embodiments of this specification, the second duration and the fourth duration can be set based on the activation duration of the battery pack in the actual business scenario, thereby improving the flexibility of the solution implementation.

[0083] In an optional implementation of this embodiment, the base station control unit 2041 is further configured to control the base station charging port 2042 to output a self-cleaning signal after the second time period, wherein the self-cleaning signal is a signal triggered by a self-cleaning instruction;

[0084] The device control unit 2021 is further configured to start a self-cleaning operation corresponding to the self-cleaning signal when a self-cleaning signal is received.

[0085] It should be noted that after the device control unit controls to turn on the charging switch, it can receive the high-level voltage signal output by the base station charging port, activate the battery pack, and put the battery pack into the charging state. Then the base station charging port can send a pulse signal corresponding to the self-cleaning signal. After the device control unit of the cleaning device detects the pulse signal corresponding to the self-cleaning signal, it can send a charge-to-discharge instruction to the battery pack, and the battery pack is converted from the charging state to the discharging state. The cleaning device as a whole performs the self-cleaning operation corresponding to the self-cleaning signal. For example, after the base station charging port outputs a high level for 4s, the battery pack is activated. At this time, the base station charging port can output a 30s square wave, which is the pulse wave of the self-cleaning signal.

[0086] For example, Figure 4 is a schematic diagram of voltage signals of another self-cleaning control process provided by an embodiment of this specification, taking a vacuum cleaner as an example. Figure 4As shown, the voltage signal of the base station charging port is: high-low 1s-high 4s-30s square wave (the 30s square wave is the pulse signal corresponding to the self-cleaning signal)-high; the voltage signal of the vacuum cleaner charging switch is: high-low 3s (pulled low at a certain time point within the 1s low time of the base station charging port, and this time point is the detection time of the device control unit, such as pulling low at 300ms)-pull high-normally high; battery pack charging voltage: low for more than 3s-high for more than 1s-30s square wave.

[0087] In the embodiments of the present specification, after the battery pack is activated, the base station control unit can transmit a self-cleaning signal to the device control unit so that the device control unit can respond to the self-cleaning signal. In this way, after the cleaning device enters a sleep state, it is still possible to control the change in the voltage signal output by the base station charging port and the switching timing of the charging switch on the cleaning device, so that the capacitor on the battery pack activation circuit is discharged first and then the battery pack is activated. This solves the problem that the battery pack cannot be activated after the cleaning device is fully charged on the base station and enters a sleep state, resulting in the inability to self-clean. This allows the cleaning device to respond to the self-cleaning signal, ensuring that the cleaning device can perform self-cleaning.

[0088] In an optional implementation of this embodiment, the self-cleaning instruction is manually triggered by the user through the base station 204.

[0089] It should be noted that after the cleaning device is put back into the base station and enters the dormant state, the self-cleaning instruction can be automatically triggered by the base station control unit, or it can be triggered by the user through the interactive controls provided by the base station; and after the cleaning device enters the base station, the self-cleaning instruction is often manually triggered by the user through the base station. In other words, the self-cleaning instruction is a manual self-cleaning instruction, which ensures that the cleaning device can still respond to the manual self-cleaning instruction triggered by the user after entering the dormant state, thereby achieving self-cleaning. Self-cleaning is not only possible before the cleaning device enters the dormant state, which enriches the timing of self-cleaning, can adapt to most application scenarios, and improves the flexibility of self-cleaning.

[0090] In an optional implementation of this embodiment, the cleaning device 202 is communicatively connected to the base station 204;

[0091] The cleaning device 202 is further configured to detect a self-cleaning instruction and send the self-cleaning instruction to the base station control unit via a communication connection, wherein the self-cleaning instruction is triggered based on a first self-cleaning control configured on the cleaning device.

[0092] Specifically, the first self-cleaning control is an interactive control configured on the cleaning device, and the first self-cleaning control can be a physical button or a virtual button on a touch screen, etc.

[0093] In actual applications, the cleaning device can be connected to the base station by communication, such as wireless connection or wired connection. The wireless connection may include Bluetooth, WIFI, etc. The user can click the first self-cleaning control on the cleaning device. At this time, the cleaning device detects the self-cleaning instruction, and then sends the self-cleaning instruction to the base station control unit through the communication connection. The base station control unit detects the self-cleaning instruction and controls the level change of the base station charging port to activate the battery pack of the cleaning device.

[0094] It should be noted that the interactive control for triggering the self-cleaning instruction can be set on the cleaning device, and the user can trigger the self-cleaning instruction by operating the cleaning device. The triggering method is more flexible and can be adapted to most application scenarios.

[0095] In an optional implementation of this embodiment, Figure 2 As shown, the self-cleaning control system of the cleaning device further includes a remote control device 206, and the remote control device 206 is communicatively connected with the base station 204;

[0096] The remote control device 206 is configured to detect a self-cleaning instruction and send the self-cleaning instruction to the base station control unit via a communication connection, wherein the self-cleaning instruction is triggered based on a second self-cleaning control configured on the remote control device.

[0097] Specifically, the second self-cleaning control is an interactive control configured on the remote control device, and the second self-cleaning control may be a physical button or a virtual button on a touch screen, etc. The remote control device is an operating device capable of remotely controlling the base station, such as a mobile phone, a remote controller, etc.

[0098] In actual applications, the remote control device can be connected to the base station by communication, such as wireless connection or wired connection. The wireless connection may include Bluetooth, WIFI, etc. The user can click the second self-cleaning control on the remote control device. At this time, the remote control device detects the self-cleaning instruction, and then sends the self-cleaning instruction to the base station control unit through the communication connection. The base station control unit detects the self-cleaning instruction and controls the level change of the base station charging port to activate the battery pack of the cleaning device.

[0099] It should be noted that users can remotely trigger self-cleaning commands through remote control devices such as mobile phones and remote controls without having to go near the base station and cleaning equipment. They can control and trigger self-cleaning commands anytime and anywhere to start self-cleaning. The operation method is more flexible and can adapt to most application scenarios, improving the user experience.

[0100] In an optional implementation of this embodiment, the first duration of the base station charging port 2042 outputting the low-level voltage signal does not exceed a set threshold.

[0101] It should be noted that the threshold is set to a pre-configured value to ensure that the duration of the base station charging port outputting the low-level voltage signal is not too long, such as 1s or 1.5s.

[0102] In actual applications, after the cleaning device enters the sleep state, some basic prompt information will still be displayed on the display screen of the cleaning device, such as the charging status, and the base station charging port outputs a low-level voltage signal, which means that the base station charging port is closed. At this time, the display screen of the cleaning device will be black. If the black screen time is too long, it will cause trouble to the user and the user interface is not friendly. Therefore, the time length for lowering the base station charging port is generally set to be smaller to avoid excessive impact on the user.

[0103] The self-cleaning control system of the cleaning equipment provided in the embodiment of the present specification, after the cleaning equipment is placed in the base station and enters the sleep state, the base station control unit can control the base station charging port to first output a low-level voltage signal and then output a high-level voltage signal when detecting a self-cleaning instruction. When the equipment control unit detects the low-level voltage signal, it can control the charging switch on the cleaning equipment to be closed to ensure the discharge time of the capacitor in the battery pack activation circuit, and then turn on the charging switch. When the charging switch is turned on, the base station charging port outputs a high-level voltage signal to activate the battery pack. After the battery pack is activated, a self-cleaning signal is sent to the cleaning equipment, so that the cleaning equipment can respond to the self-cleaning signal and start the self-cleaning operation. In this way, after the cleaning device enters the sleep state, the discharge time of the capacitor in the battery pack activation circuit is guaranteed by controlling the charging port of the base station to output a low-level voltage signal first and then a high-level voltage signal, so that the device control unit can receive the high-level voltage signal to activate the battery pack; that is, by controlling the change of the voltage signal output by the charging port of the base station and the switching timing of the charging switch on the cleaning device, the capacitor in the battery pack activation circuit can be discharged first and then the battery pack can be activated, which solves the problem that the battery pack cannot be activated and the battery pack cannot be self-cleaned after the cleaning device is fully charged on the base station and enters the sleep state, so that the cleaning device can start the self-cleaning operation, ensuring that the cleaning device can perform self-cleaning.

[0104] Figure 5 is a structural block diagram of a self-cleaning control system of another cleaning device provided in an embodiment of this specification, such as Figure 5As shown, the self-cleaning control system includes a cleaning device 502, a base station 504 and an adapter 506. The base station 504 is used to perform a self-cleaning operation on the cleaning device 502. The adapter 506 is used to charge the cleaning device 502. The cleaning device 502 includes a device control unit 5021, a charging terminal 5022 and a battery pack 5023. The adapter 506 includes an adapter control unit 5061 and an adapter charging port 5062. The cleaning device 502 is placed on the base station 504, and the charging terminal 5022 of the cleaning device 502 is connected to the adapter charging port 5062 of the adapter 506. The cleaning device 502 is in a dormant state.

[0105] The adapter control unit 5061 is configured to control the adapter charging port 5062 to output a first trigger signal when a self-cleaning instruction is detected, wherein the first trigger signal is different from a power supply signal of the adapter charging port 5062;

[0106] The device control unit 5021 is configured to control the charging switch on the cleaning device 502 to be turned off and then turned on again when detecting that the adapter charging port 5062 outputs a first trigger signal, so as to activate the battery pack 5023 of the cleaning device 502 and start the self-cleaning operation of the cleaning device 502 and the base station 504, wherein the charging switch is used to control the charging status of the charging terminal 5022.

[0107] It should be noted that the cleaning device can be placed on the base station, and the base station can be used to self-clean the cleaning device, and the cleaning device can be charged through the adapter, that is, the charging function is separated from the base station to the adapter.

[0108] Specifically, the first trigger signal is a pre-configured specific signal, which is different from the power supply signal of the adapter charging port. The first trigger signal is a signal that the device control unit can receive in a dormant state to activate the battery pack. For example, the first trigger signal can be a change signal of a low-level voltage signal first and then a high-level voltage signal, or the first trigger signal can also be a specific square wave or pulse wave.

[0109] In a possible implementation, an interactive control may be provided on the cleaning device to trigger a self-cleaning instruction. Specifically, the user may click on the interactive control on the cleaning device, at which point the cleaning device detects the self-cleaning instruction, and then sends the self-cleaning instruction to the adapter control unit via a communication connection. The adapter control unit detects the self-cleaning instruction and controls the charging port of the base station to output a first trigger signal. When the device control unit detects the first trigger signal output by the adapter charging port, it controls the charging switch on the cleaning device to be turned off and then turned on to activate the battery pack of the cleaning device and start the self-cleaning operation of the cleaning device and the base station.

[0110] In another possible implementation, the self-cleaning control system of the cleaning device can also be connected to an interactive control, which is connected to the adapter. When the user triggers the interactive control, the adapter control unit can detect the self-cleaning instruction and control the base station charging port to output a first trigger signal to activate the battery pack of the cleaning device.

[0111] In the self-cleaning control system of the cleaning device provided in the embodiment of this specification, the cleaning device is placed in the base station, and the cleaning device is charged through the adapter. After the cleaning device enters the dormant state, the adapter can detect the self-cleaning instruction and control the charging port of the base station to output the first trigger signal. When the device control unit detects the first trigger signal, it can control the charging switch on the cleaning device to close to ensure the discharge time of the capacitor on the battery pack activation circuit, and then turn on the charging switch to activate the battery pack and start the self-cleaning operation. In this way, after the cleaning device enters the dormant state, a specific trigger signal is output through the adapter charging port, so that the device control unit can control the switching timing of the charging switch, and then the capacitor on the battery pack activation circuit can be discharged first, and then the battery pack is activated, which solves the problem that the cleaning device cannot activate the battery pack after it is fully charged on the base station and enters the dormant state, resulting in the inability to self-clean, so that the cleaning device can start the self-cleaning operation, ensuring that the cleaning device can perform self-cleaning.

[0112] Above Figure 5 The figure shows a schematic scheme of a self-cleaning control system of a cleaning device in this embodiment. Figure 5 The technical solution of the self-cleaning control system of the cleaning equipment shown is the same as the above Figure 2 The technical solution of the self-cleaning control system of the cleaning equipment shown belongs to the same concept. Figure 5 For details not described in detail in the technical solution of the self-cleaning control system of the cleaning device shown in the figure, please refer to the above Figure 2 Description of the technical solution of the self-cleaning control system of the cleaning equipment shown.

[0113] Figure 6 is a flow chart of a self-cleaning control method for a cleaning device provided in an embodiment of the present specification, which is applied to a base station control unit of a base station, a cleaning device is placed on the base station, a charging end of the cleaning device is connected to a base station charging port of the base station, and the cleaning device is in a dormant state, such as Figure 6 The specific steps shown include:

[0114] Step 602: Determine whether a self-cleaning instruction is detected.

[0115] The self-cleaning instruction may be triggered by a third self-cleaning control configured on the base station, and the third self-cleaning control trigger is an interactive control that triggers the self-cleaning operation. Alternatively, the self-cleaning instruction may also be provided by the cleaning device or the remote control device, that is, triggered by an interactive control provided by the cleaning device or the remote control device.

[0116] Step 604: If yes, control the base station charging port to first output a low level voltage signal and then output a high level voltage signal, wherein the change in the output voltage signal of the base station charging port is used to activate the battery pack of the cleaning device and start the self-cleaning operation of the cleaning device.

[0117] In an optional implementation of this embodiment, the charging port of the base station is controlled to output a low-level voltage signal first and then a high-level voltage signal. The specific implementation process may be as follows:

[0118] Control the charging port of the base station to output a low-level voltage signal of a first duration;

[0119] After the first duration is reached, the charging port of the base station is controlled to output a high-level voltage signal for a second duration, wherein the second duration is greater than the first duration.

[0120] Among them, the first duration of the base station charging port outputting the low-level voltage signal does not exceed the set threshold.

[0121] It should be noted that the second time period and the fourth time period can be set based on the activation time period of the battery pack, and the difference between the fourth time period and the second time period is the activation time period of the battery pack. The fourth time period is the time period for turning off the charging switch on the cleaning device.

[0122] In addition, after the cleaning device enters the sleep state, some basic prompt information will still be displayed on the display screen of the cleaning device, such as the charging status, and the base station charging port outputs a low-level voltage signal, which means that the base station charging port is closed. At this time, the display screen of the cleaning device will be black. If the black screen time is too long, it will cause trouble to the user and the user interface is unfriendly. Therefore, the time for lowering the base station charging port is generally set to a smaller value to avoid excessive impact on the user.

[0123] In the embodiments of the present specification, the charging port of the base station can be controlled to output a low-level voltage signal of a first duration first, so as to provide a sufficient duration for the device control unit to detect the low-level voltage signal, thereby ensuring that the device control unit can detect the low-level voltage signal output by the charging port of the base station; in addition, after reaching the first duration, the charging port of the base station can be controlled to output a high-level voltage signal of a second duration, wherein the second duration is greater than the first duration, thereby providing sufficient time for activating the battery pack on the cleaning device, thereby ensuring that the battery pack can be successfully activated, thereby improving the success rate of the battery pack activation, and thereby ensuring the response rate of the self-cleaning instruction.

[0124] In an optional implementation of this embodiment, after controlling the charging port of the base station to output a low-level voltage signal first and then a high-level voltage signal, the method further includes:

[0125] After the second time period, the charging port of the base station is controlled to output a self-cleaning signal.

[0126] It should be noted that after the battery pack is activated, the base station control unit can transmit a self-cleaning signal to the device control unit, so that the device control unit can respond to the self-cleaning signal and start the self-cleaning operation.

[0127] The self-cleaning control method for a cleaning device provided in an embodiment of the present specification ensures the discharge time of the capacitor in the battery pack activation circuit by controlling the charging port of the base station to output a low-level voltage signal first and then a high-level voltage signal after the cleaning device enters a sleep state, so that the device control unit can receive a high-level voltage signal to activate the battery pack; that is, by controlling the change of the voltage signal output by the charging port of the base station and the switching timing of the charging switch on the cleaning device, the capacitor in the battery pack activation circuit can be discharged first and then the battery pack can be activated, which solves the problem that the self-cleaning signal cannot activate the battery pack and causes the cleaning device to be unable to self-clean after it is fully charged on the base station and enters a sleep state, so that the cleaning device can start the self-cleaning operation, ensuring that the cleaning device can perform self-cleaning.

[0128] Figure 7 is a flow chart of another self-cleaning control method for a cleaning device provided in an embodiment of the present specification, which is applied to a device control unit of the cleaning device, wherein the cleaning device also includes a charging terminal and a battery pack, the charging terminal of the cleaning device is connected to the base station charging port of the base station, and the cleaning device is in a dormant state, such as Figure 7 The specific steps shown include:

[0129] Step 702: Detect whether the charging port of the base station outputs a low-level voltage signal, wherein the charging port of the base station first outputs a low-level voltage signal and then outputs a high-level voltage signal when the base station control unit detects a self-cleaning instruction.

[0130] The self-cleaning instruction is manually triggered by the user through the base station. Alternatively, the self-cleaning instruction can also be triggered by an interactive control provided by the cleaning device or remote control device and sent to the base station control unit.

[0131] Step 704: If yes, then control the charging switch on the cleaning device to turn off and then turn on the charging switch to activate the battery pack of the cleaning device and start the self-cleaning operation of the cleaning device. The charging switch is used to control the charging status of the charging end. When the charging switch is turned on, the base station charging port outputs a high-level voltage signal.

[0132] In an optional implementation of this embodiment, the charging switch on the cleaning device is controlled to be turned off and then turned on. The specific implementation process may be as follows:

[0133] Determining whether a low-level voltage signal lasting a third duration is detected, wherein the third duration is less than or equal to the first duration;

[0134] If so, turn off the charging switch on the cleaning device, and turn on the charging switch after a fourth time period to activate the battery pack of the cleaning device and start the self-cleaning operation of the cleaning device, wherein the fourth time period is less than the second time period.

[0135] It should be noted that the second time and the fourth time can be set based on the activation time of the battery pack, and the difference between the fourth time and the second time is the activation time of the battery pack. The second time is the time for raising the charging port of the base station.

[0136] In the embodiment of the present specification, the device control unit determines that the current base station charging port outputs a low-level voltage signal only when it detects a low-level voltage signal that lasts for a third period of time, and controls the charging switch on the cleaning device to close, thereby avoiding misjudgment, thereby avoiding false activation of the battery pack, and improving the accuracy of battery pack activation; in addition, when a low-level voltage signal that lasts for a third period of time is detected, it indicates that self-cleaning is currently required, that is, the battery pack needs to be activated. Since the cleaning device will enter a dormant state after being fully charged, the capacitor of the activation circuit on the cleaning device is in a fully charged state, and therefore the charging switch on the cleaning device can be closed to provide time for the capacitor to discharge, thereby ensuring that the battery pack can be activated, thereby ensuring that it can respond to the self-cleaning instruction after entering the dormant state.

[0137] In an optional implementation of this embodiment, after controlling to turn off the charging switch on the cleaning device and then turn on the charging switch, the method further includes:

[0138] When a self-cleaning signal is received, the self-cleaning operation of the cleaning device is started.

[0139] It should be noted that after the battery pack is activated, the base station control unit can transmit a self-cleaning signal to the device control unit, so that the device control unit can respond to the self-cleaning signal and start the self-cleaning operation of the cleaning device.

[0140] The self-cleaning control method for a cleaning device provided in an embodiment of the present specification ensures the discharge time of the capacitor in the battery pack activation circuit by controlling the charging port of the base station to output a low-level voltage signal first and then a high-level voltage signal after the cleaning device enters a sleep state, so that the device control unit can receive a high-level voltage signal to activate the battery pack; that is, by controlling the change of the voltage signal output by the charging port of the base station and the switching timing of the charging switch on the cleaning device, the capacitor in the battery pack activation circuit can be discharged first and then the battery pack can be activated, which solves the problem that the self-cleaning signal cannot activate the battery pack and causes the cleaning device to be unable to self-clean after it is fully charged on the base station and enters a sleep state, so that the cleaning device can start the self-cleaning operation, ensuring that the cleaning device can perform self-cleaning.

[0141] Figure 8 is a flow chart of another self-cleaning control method for a cleaning device provided in an embodiment of the present specification, which is applied to a device control unit of the cleaning device, wherein the cleaning device also includes a charging terminal and a battery pack, the charging terminal of the cleaning device is connected to the base station charging port of the base station, and the cleaning device is in a dormant state, such as Figure 8 The method shown includes:

[0142] Step 802: Detect whether the base station charging port outputs a second trigger signal, wherein the base station charging port outputs the second trigger signal when the base station control unit detects a self-cleaning instruction, and the second trigger signal is different from the power supply signal of the base station charging port.

[0143] Step 804: If yes, then control the charging switch on the cleaning device to be turned off and then turned on to activate the battery pack of the cleaning device and start the self-cleaning operation of the cleaning device, wherein the charging switch is used to control the charging state of the charging terminal.

[0144] It should be noted that the second trigger signal is a pre-configured specific signal, which is different from the power supply signal of the adapter charging port. The first trigger signal is a signal that the device control unit can receive in a dormant state to activate the battery pack. For example, the first trigger signal can be a change signal of a low-level voltage signal first and then a high-level voltage signal, or the first trigger signal can also be a specific square wave or pulse wave.

[0145] In practical applications, the second trigger signal may be output by the base station charging port when the base station control unit detects a self-cleaning instruction, and the self-cleaning instruction may be triggered by a cleaning device, a base station or a remote control device.

[0146] In the self-cleaning control system of the cleaning equipment provided in the embodiments of this specification, after the cleaning equipment is placed in the base station and enters the dormant state, the base station control unit can detect the self-cleaning instruction and control the base station charging port to output a second trigger signal. When the equipment control unit detects the second trigger signal, it can control the charging switch on the cleaning equipment to close to ensure the discharge time of the capacitor in the battery pack activation circuit, and then turn on the charging switch to activate the battery pack and start the self-cleaning operation. In this way, after the cleaning equipment enters the dormant state, a specific trigger signal is output through the base station charging port so that the equipment control unit can receive it to control the switching timing of the charging switch, so that the capacitor in the battery pack activation circuit can be discharged first and then the battery pack can be activated, which solves the problem that the cleaning equipment cannot self-clean after being fully charged on the base station and enters the dormant state, so that the cleaning equipment can start the self-cleaning operation, ensuring that the cleaning equipment can perform self-cleaning.

[0147] The above is a schematic scheme of a self-cleaning control method for a cleaning device of this embodiment. It should be noted that the technical scheme of the self-cleaning control method for the cleaning device and the technical scheme of the self-cleaning control system of the cleaning device described above belong to the same concept, and the details of the technical scheme of the self-cleaning control method for the cleaning device that are not described in detail can be referred to the description of the technical scheme of the self-cleaning control system of the cleaning device described above.

[0148] The following combination Fig. 9 Taking the application of the self-cleaning control method of the cleaning device provided in this specification in a vacuum cleaner as an example, the self-cleaning control method of the cleaning device is further described. Fig. 9 This is a processing flow chart of a self-cleaning control method for a cleaning device applied to a vacuum cleaner provided in an embodiment of this specification. The vacuum cleaner corresponds to a base station. The vacuum cleaner is placed in the base station and enters a dormant state after being fully charged. Fig. 9 The self-cleaning control method specifically comprises the following steps:

[0149] Step 902: When the user manually starts self-cleaning, the base station mainboard MCU detects the self-cleaning instruction and controls the base station charging port to be pulled low for 1 second and then pulled high for 4 seconds.

[0150] Step 904: After the vacuum cleaner mainboard MCU detects a 300ms low charging level, it turns off the vacuum cleaner charging switch for 3s, and then turns on the vacuum cleaner charging switch. When the vacuum cleaner charging switch is turned on, the base station charging port is at a high level.

[0151] Among them, within 3 seconds of turning off the vacuum cleaner charging switch, the capacitor of the activation circuit on the vacuum cleaner is discharged. When the vacuum cleaner charging switch is turned on again after 3 seconds, the charging port of the base station is at a high level. After the vacuum cleaner charging switch is turned on, the battery pack is given a high-level activation time of more than 1 second to ensure that the battery pack can be activated and can respond to the self-cleaning command of the vacuum cleaner.

[0152] Step 906: The base station mainboard MCU controls the base station charging port to output a 30s square wave, which is a pulse wave corresponding to the self-cleaning signal, and the self-cleaning signal is a signal triggered by the self-cleaning instruction.

[0153] Step 908: The vacuum cleaner mainboard MCU receives the 30s square wave and starts the self-cleaning operation.

[0154] The self-cleaning control method for a cleaning device provided in the embodiments of this specification, after the vacuum cleaner enters a dormant state, by controlling the base station charging port to first be pulled low and then pulled high, the discharge time of the capacitor in the battery pack activation circuit is guaranteed, so that the device mainboard MCU can receive a high-level voltage signal to activate the battery pack; that is, by controlling the change of the voltage signal output by the base station charging port and the switching timing of the vacuum cleaner charging switch, the capacitor in the battery pack activation circuit can be discharged first and then the battery pack can be activated, which solves the problem that the vacuum cleaner cannot self-clean because the battery pack cannot be activated after being fully charged on the base station and enters a dormant state, so that the vacuum cleaner can respond to the self-cleaning signal transmitted by the base station controller, start the self-cleaning operation, and ensure that the vacuum cleaner can perform self-cleaning.

[0155] The following describes the self-cleaning control method of the cleaning device provided by the embodiment of the present invention in combination with specific application scenarios:

[0156] Application scenario 1:

[0157] The user uses a handheld vacuum cleaner to clean the room. After cleaning, the user puts the handheld vacuum cleaner back to the base station and charges the handheld vacuum cleaner through the base station. The handheld vacuum cleaner will enter a dormant state after it is fully charged. The user clicks the self-cleaning trigger control on the base station. At this time, the base station mainboard MCU detects the self-cleaning command and controls the base station charging port to be pulled low for 1s and then pulled high for 4s. After the handheld vacuum cleaner mainboard MCU detects a 300ms charging low level, it turns off the handheld vacuum cleaner charging switch for 3s, and then turns on the handheld vacuum cleaner charging switch. When the handheld vacuum cleaner charging switch is turned on, the base station charging port is at a high level to ensure that the battery pack of the handheld vacuum cleaner can be activated and can respond to the self-cleaning command. Afterwards, the base station mainboard MCU controls the base station charging port to output a 30s square wave, which is a pulse wave corresponding to the self-cleaning signal. The handheld vacuum cleaner mainboard MCU receives the 30s square wave, starts the self-cleaning operation, the roller brush of the handheld vacuum cleaner rotates, and the vacuum source of the base station is started, so that the dirt on the roller brush and the garbage in the dust bucket of the handheld vacuum cleaner can be sucked into the dust collection device in the base station for storage, thereby realizing self-cleaning of the handheld vacuum cleaner. After completing self-cleaning, it enters the charging state again.

[0158] Application scenario 2:

[0159] The user uses a floor scrubber with a drying function to clean the room. After cleaning, the floor scrubber is placed back to the base station and charged through the base station. The floor scrubber will enter a dormant state after being fully charged. The user clicks the self-cleaning trigger control on the floor scrubber. At this time, the floor scrubber mainboard MCU detects the self-cleaning instruction. The floor scrubber mainboard MCU transmits the self-cleaning instruction to the base station mainboard MCU via Bluetooth. After receiving the self-cleaning instruction, the base station mainboard MCU controls the base station charging port to be pulled low for 1s and then pulled high for 4s. After the floor scrubber mainboard MCU detects a 300ms charging low level, it turns off the floor scrubber charging switch for 3s, and then turns on the floor scrubber charging switch. When the floor scrubber charging switch is turned on, the base station charging port is at a high level to ensure that the floor scrubber's battery pack can be activated and respond to the self-cleaning instruction. Afterwards, the MCU of the base station mainboard controls the charging port of the base station to output a 30s square wave, which is the pulse wave corresponding to the self-cleaning signal. The MCU of the floor scrubber mainboard receives the 30s square wave and starts the self-cleaning operation. The roller brush of the floor scrubber rotates, sprays water, and starts the suction motor to suck the stains on the roller brush into the sewage bucket of the host for storage. Then the base station starts the drying roller brush function to realize self-cleaning of the floor scrubber. After completing self-cleaning, it enters the charging state again.
