[0048] In order to illustrate the technical solution described in this application, specific embodiments are provided below.

[0049] Figure 1 FIG1 shows a principle block diagram of a base station control circuit 10 provided in an embodiment of the present application. Figure 1 As shown, the base station control circuit 10 includes a wireless communication control module 101, an infrared emission module 102 and a motor control module 103. The wireless communication control module 101 is electrically connected to the infrared emission module 102 and the motor control module 103 respectively; the wireless communication control module 101 is used to control the infrared emission module 102 to output infrared signals, so that the cleaning robot can dock with the base station according to the infrared signals; the wireless communication control module 101 is also used to control the motor control module 103, so that the functional motor driven by the motor control module 103 performs corresponding work; the wireless communication control module 101 is a Bluetooth chip or a WiFi chip.

[0050] It should be noted that the wireless communication control module 101 can be used to communicate wirelessly with external devices, including cleaning robots, smart cleaning devices (handheld vacuum cleaners, pet hair removers, etc.) or terminal devices (mobile phones, tablet computers, etc.).

[0051] Specifically, when the wireless communication control module 101 controls the infrared transmitting module 102 to output an infrared signal, and the infrared receiver of the cleaning robot receives the infrared signal, the cleaning robot can move toward the base station according to the infrared signal, thereby completing the docking with the base station. After the docking is successful, the base station can exchange information with the cleaning robot through the wireless communication control module 101. Then, the wireless communication control module 101 controls the motor control module 103 according to the interactive information, so that the motor control module 103 drives the functional motor to perform corresponding work to cooperate with the cleaning robot to perform operations such as charging, dust collection or water change.

[0052] For example, Figure 2 Schematic diagram of the structure of the base station 100 and the cleaning robot 200. When the cleaning robot 200 needs to dock with the base station 100, the cleaning robot 200 runs toward the base station 100, the infrared emitting tube 120 of the base station 100 sends an infrared signal to the cleaning robot 200, and the infrared receiving tube 220 of the cleaning robot 200 receives the infrared signal sent by the infrared emitting tube 120, and communicates with the base station 100, thereby guiding the cleaning robot 200 to dock with the base station 100. When the first electrode sheet 210 of the cleaning robot 200 contacts the second electrode sheet 110 of the base station 100, it indicates that the cleaning robot 200 and the base station 100 have completed docking. The cleaning robot 200 may include a sweeping robot, a mopping robot, and a sweeping and mopping robot.

[0053] For example, Figure 3 This is a circuit diagram of the Bluetooth chip U1 used in the wireless communication control module 101. Pins 17 MOTOR_PWM_P, 18 MOTOR_PWM_N, 19 MOTOR_EN, 3 MOTOR_ADC, 33 AC_MOTOR_CTL, and 27 SWDIO / ZERO_DET of the Bluetooth chip U1 are all used to connect to the motor control module 103. Pins 1 IR_FRONT_R, 5 IR_MID_L, 6 IR_MID_R, and 40 IR_FRONT_L of the Bluetooth chip U1 are all used to connect to the infrared transmitter module 102.

[0054] It should be noted that the wireless communication control module 101 can implement control functions based on a customized software control protocol.

[0055] In the base station control circuit 10 provided in the embodiment of the present application, the wireless communication control module 101 controls the infrared emission module 102 to output infrared signals, and can also control the motor control module 103 so that the motor control module 103 drives the functional motor to perform corresponding work. In addition, the wireless communication control module 101 also has a wireless communication function. Therefore, only one wireless communication control module 101 is needed to realize the two functions of base station control and wireless communication, and there is no need to set up another main control chip to control the base station, thereby significantly reducing the design cost of the base station control circuit 10. Moreover, compared with the prior art, after using a Bluetooth chip to realize wireless communication interaction with the cleaning robot, and then using a main control chip to control the base station, in the present application, only the wireless communication control module 101 is used to realize wireless communication and control at the same time, which shortens the time for the base station to respond to instructions and ensures that the base station can cooperate with the cleaning robot to efficiently complete the corresponding operation.

[0056] In one embodiment of the present application, the infrared emission module 102 includes multiple infrared emission units, each of which is electrically connected to the wireless communication control module 101, and the infrared emission unit is used to output an infrared signal according to the infrared control signal output by the wireless communication control module 101.

[0057] Specifically, such as Figure 4 As shown, the infrared transmitting module 102 includes four infrared transmitting units (1021, 1022, 1023, 1024), each of which is electrically connected to the Bluetooth chip U1, receives the infrared control signal output by the Bluetooth chip U1, and outputs a corresponding infrared signal according to the corresponding infrared control signal. Among them, the first infrared transmitting unit 1021 is electrically connected to the pin 40IR_FRONT_L of the Bluetooth chip U1, and is used to receive the infrared control signal output by the pin 40IR_FRONT_L of the Bluetooth chip U1. The second infrared transmitting unit 1022 is electrically connected to the pin 1IR_FRONT_R of the Bluetooth chip U1, and is used to receive the infrared control signal output by the pin 1IR_FRONT_R of the Bluetooth chip U1. The third infrared transmitting unit 1023 is electrically connected to pin 5IR_MID_L of the Bluetooth chip U1, and is used to receive the infrared control signal output by pin 5IR_MID_L of the Bluetooth chip U1. The fourth infrared transmitting unit 1024 is electrically connected to pin 6IR_MID_R of the Bluetooth chip U1, and is used to receive the infrared control signal output by pin 6IR_MID_R of the Bluetooth chip U1.

[0058] It should be noted that the number of infrared emitting units is not limited here, and designers can increase / decrease the number of infrared emitting units according to actual needs. It should be noted that the number of infrared emitting units is at least two.

[0059] In one embodiment of the present application, Figure 4 As shown, the working principle of the infrared emitting unit is described here by taking the first infrared emitting unit 1021 as an example. The infrared emitting unit 1021 includes a first switching device Q1 and an infrared emitting tube IR1. The control end of the first switching device Q1 is electrically connected to the wireless communication control module 101, the first conduction end of the first switching device Q1 is electrically connected to the first end of the infrared emitting tube IR1, the second conduction end of the first switching device Q1 is grounded, and the second end of the infrared emitting tube IR1 is used to be electrically connected to the VDD-3V3 power supply.

[0060] Specifically, the first switching device Q1 is turned on or off according to the infrared control signal output by the Bluetooth chip U1, and controls the infrared emitting tube IR1 to emit an infrared signal. If the first switching device Q1 is a high-level conductive device, when the infrared control signal is a high-level signal, the first switching device Q1 is turned on, the infrared emitting tube IR1 is powered, and it outputs an infrared signal. When the infrared control signal is a low-level signal, the first switching device Q1 is turned off, the infrared emitting tube IR1 is not powered, and it cannot output an infrared signal. If the first switching device Q1 is a low-level conductive device, when the infrared control signal is a high-level signal, the first switching device Q1 is turned off, the infrared emitting tube IR1 is not powered, and it cannot output an infrared signal. When the infrared control signal is a low-level signal, the first switching device Q1 is turned on, the infrared emitting tube IR1 is powered, and it outputs an infrared signal.

[0061] It should be noted that the first switching device Q1 can be a first transistor, the base of the first transistor serves as the control end of the first switching device Q1, the collector of the first transistor serves as the first conduction end of the first switching device Q1, and the emitter of the first transistor serves as the second conduction end of the first switching device Q1.

[0062] Exemplarily, the first transistor may be an NPN transistor.

[0063] In one embodiment of the present application, Figure 4 As shown, taking the first infrared emitting unit 1021 as an example, the infrared emitting unit 1021 also includes a second switching device Q2, the control end of the second switching device Q2 is electrically connected to the second conduction end of the first switching device Q1, the first conduction end of the second switching device Q2 is electrically connected to the control end of the first switching device Q1, and the second conduction end of the second switching device Q2 is grounded, so that the infrared emitting unit 1021 outputs a stable infrared signal.

[0064] Specifically, the second switching device Q2 and the first switching device Q1 form a constant current source circuit, which can ensure that the current of the infrared emitting tube is more stable.

[0065] It should be noted that the second switching device Q2 can be a second transistor, the base of the second transistor serves as the control end of the second switching device Q2, the collector of the second transistor serves as the first conduction end of the second switching device Q2, and the emitter of the second transistor serves as the second conduction end of the second switching device Q2.

[0066] Exemplarily, the second transistor may be an NPN transistor.

[0067] It should be noted that this application only shows one component composition of the infrared emission module 102, which does not mean that only this component composition can realize the function of the infrared emission module 102. Other components that can realize the function can also be replaced, and the present invention is not limited to this.

[0068] It should be noted that the four infrared emitting units (1021, 1022, 1023, 1024) in this application include four infrared emitting tubes, namely IR1, IR2, IR3 and IR4. The relative position relationship of the four infrared emitting tubes on the base station is as follows: Figure 5 As shown in the figure, IR1 is located at the front left of the base station, IR2 is located at the center left of the base station, IR3 is located at the center right of the base station, and IR4 is located at the front right of the base station. S1, S2, S3, and S4 are the areas covered by the infrared signals of infrared tubes IR1, IR2, IR3, and IR4, respectively.

[0069] It should be noted that when the Bluetooth chip U1 needs to control the infrared emitting tube to emit an infrared signal, pin 1IR_FRONT_R, pin 5IR_MID_L, pin 6IR_MID_R and pin 40IR_FRONT_L of the Bluetooth chip U1 respectively output high and low level infrared control signals alternately with different duty cycles, so that the infrared emitting tubes IR1, IR2, IR3 and IR4 respectively emit infrared signals with different infrared code values, so that the cleaning robot can confirm the specific position of the cleaning robot relative to the base station by identifying different infrared code values, and thus accurately dock with the base station.

[0070] It should be noted that this application only shows the case where four infrared emitting tubes are provided. The number of infrared emitting tubes can be increased or decreased according to actual needs, and the relative positions of all infrared emitting tubes can be adjusted accordingly to adjust the area covered by the infrared signal. It should be noted that the number of infrared emitting tubes is at least two.

[0071] In one embodiment of the present application, when the wireless communication control module 101 establishes a connection with the cleaning robot and receives a docking request sent by the cleaning robot, the wireless communication control module 101 is used to control the infrared emission module 102 to output an infrared signal.

[0072] Specifically, with respect to the prior art, once the base station is powered on, the infrared emission module 102 is always in working state, which may cause the problem of shortening the service life of the infrared emission module 102. The base station control circuit 10 proposed in the present application, only when the cleaning robot runs to the Bluetooth signal area (preset area) where the Bluetooth control module can cover and establish a connection, the wireless communication control module 101 is connected to the cleaning robot by Bluetooth and outputs an infrared control signal to the infrared emission module 102. The infrared emission module 102 outputs an infrared signal according to the infrared control signal, so that the cleaning robot is docked with the base station according to the infrared signal. Therefore, the infrared emission module 102 will only work when the cleaning robot runs to the preset area, which can avoid unnecessary continuous operation of the infrared emission module 102 after the base station is powered on, thereby extending the service life of the infrared emission module 102.

[0073] It should be noted that if there are multiple base stations in the same environment, the cleaning robot can communicate via Bluetooth to notify the infrared transmitting tube of a specific base station to send out an infrared signal, thereby avoiding infrared signal interference and preventing the cleaning robot from docking to the wrong base station.

[0074] For example, if there are dust collection base stations and water exchange base stations in the same environment, and a cleaning robot needs to collect dust, the cleaning robot will move near the dust collection base station and notify the dust collection base station to control the infrared emission tube to emit infrared signals, while the water exchange base station keeps the infrared emission tube from emitting infrared signals. This prevents the cleaning robot from receiving infrared signals from the water exchange base station and docking with the water exchange base station.

[0075] In one embodiment of the present application, Figure 6 As shown, the motor control module 103 includes a switching motor control module 1031 and a dust extraction motor control module 1032, and the functional motors include a switching motor 20 and a dust extraction motor 30. The input end of the switching motor control module 1031 and the input end of the dust extraction motor control module 1032 are both electrically connected to the wireless communication control module 101, the output end of the switching motor control module 1031 is electrically connected to the switching motor 20, and the output end of the dust extraction motor control module 1032 is electrically connected to the dust extraction motor 30.

[0076] Specifically, the input end of the switching element motor control module 1031 is electrically connected to the wireless communication control module 101, and is used to receive the switching element motor drive signal output by the wireless communication control module 101, and control the switching element motor 20 according to the switching element motor drive signal to open or close the first dust collection channel or the second dust collection channel of the base station. The first dust collection channel in the base station is used to collect dust for the cleaning robot, and the second dust collection channel in the base station is used to collect dust for intelligent cleaning devices (such as handheld vacuum cleaners, pet hair vacuums, etc.).

[0077] The input end of the dust extraction motor control module 1032 is electrically connected to the wireless communication control module 101, and is used to receive the dust extraction motor drive signal output by the wireless communication control module 101, and control the dust extraction motor 30 according to the dust extraction motor drive signal to extract dust and garbage from the cleaning robot or intelligent cleaning equipment.

[0078] For example, when the cleaning robot is successfully docked with the base station, the cleaning robot sends a dust collection instruction to the base station. The wireless communication control module 101 receives the dust collection instruction of the cleaning robot. If it is detected that the first dust collection channel is in a closed state, the wireless communication control module 101 outputs a switching motor driving signal to the switching motor control module 1031, so that the switching motor control module 1031 controls the switching motor 20 to work, thereby opening the first dust collection channel. Furthermore, the wireless communication control module 101 outputs a dust extraction motor driving signal to the dust extraction motor control module 1032, so that the dust extraction motor 30 works, so that the dust of the cleaning robot can be extracted into the dust collection chamber of the base station. For another example, when the handheld vacuum cleaner is successfully docked with the base station, the handheld vacuum cleaner sends a dust collection instruction to the base station, and the wireless communication control module 101 receives the dust collection instruction of the handheld vacuum cleaner. If it is detected that the second dust collection channel is in a closed state, the wireless communication control module 101 outputs a switching component motor drive signal to the switching component motor control module 1031, so that the switching component motor control module 1031 controls the switching component motor 20 to work, thereby opening the second dust collection channel. Furthermore, the wireless communication control module 101 outputs a dust extraction motor drive signal to the dust extraction motor control module 1032, so that the dust extraction motor 30 works, so that the dust from the handheld vacuum cleaner can be extracted into the dust collection chamber of the base station.

[0079] It should be noted that, in view of the fact that the existing technology can only collect dust from cleaning robots, the present application adds a switching component motor control module 1031 that can open or close the first dust collection channel or the second dust collection channel of the base station, thereby being able to collect dust from cleaning robots and intelligent cleaning equipment, and the functions of the base station are more abundant.

[0080] It should be noted that the motor control module 103 can also include a self-priming pump control module and a peristaltic pump control module. Accordingly, the functional motor can also include a self-priming pump motor and a peristaltic pump motor. If the cleaning robot needs to return to the base station to change water, the self-priming pump control module can control the self-priming pump motor to work according to the self-priming pump motor drive signal output by the wireless communication control module 101, so that the base station extracts sewage from the cleaning robot. The peristaltic pump control module can control the peristaltic pump motor to work according to the peristaltic pump motor drive signal output by the wireless communication control module 101, so that the base station adds cleaning fluid to the cleaning robot.

[0081] In one embodiment of the present application, the input end of the switching element motor control module 1031 includes a first input end and a second input end, and the first input end and the second input end are both electrically connected to the wireless communication control module 101. The output end of the switching element motor control module 1031 includes a first output end and a second output end, and the first output end and the second output end are both electrically connected to the switching element motor 20.

[0082] Specifically, the switching element motor drive signal includes a first switching element motor drive signal and a second switching element motor drive signal. The first input end of the switching element motor control module 1031 is used to receive the first switching element motor drive signal output by the wireless communication control module 101, and then control the switching element motor 20 to rotate in a first direction through the first output end. The second input end of the switching element motor control module 1031 is used to receive the second switching element motor drive signal output by the wireless communication control module 101, and then control the switching element motor 20 to rotate in a second direction through the second output end. The first direction and the second direction are opposite.

[0083] For example, the first direction can be selected as a clockwise direction, and the second direction can be selected as a counterclockwise direction. It can be set that when the first switching element motor drive signal is a high-level signal, the switching element motor control module 1031 controls the switching element motor 20 to rotate clockwise. When the second switching element motor drive signal is a high-level signal, the switching element motor control module 1031 controls the switching element motor 20 to rotate counterclockwise.

[0084] In one embodiment of the present application, Figure 7 As shown, the switching element motor control module 1031 includes a motor driving chip U2 , an input end of the motor driving chip U2 is electrically connected to the wireless communication control module 101 , and an output end of the motor driving chip U2 is electrically connected to the switching element motor 20 .

[0085] It should be noted that, in this embodiment, the input end of the motor driver chip U2 serves as the input end of the switching element motor control module 1031 , and the output end of the motor driver chip U2 serves as the output end of the switching element motor control module 1031 .

[0086] Exemplarily, pins 1IN1 and 2IN2 of the motor driver chip U2 serve as input terminals of the motor driver chip U2, and pins 6OUT1 and 7OUT2 of the motor driver chip U2 serve as output terminals of the motor driver chip U2. Pin 1IN1 of the motor driver chip U2 serves as the first input terminal of the motor driver chip U2 and is electrically connected to pin 17MOTOR_PWM_P of the Bluetooth chip U1. When the first switching element motor drive signal output by pin 17MOTOR_PWM_P of the Bluetooth chip U1 is a high-level signal, the motor driver chip U2 controls the switching element motor 20 to rotate in the first direction. Pin 2IN2 of the motor driver chip U2 serves as the second input terminal of the motor driver chip U2 and is electrically connected to pin 18MOTOR_PWM_N of the Bluetooth chip U1. When the second switching element motor drive signal output by pin 18MOTOR_PWM_N of the Bluetooth chip U1 is a high-level signal, the motor driver chip U2 controls the switching element motor 20 to rotate in the second direction.

[0087] It should be noted that pin 3nSLP of motor driver chip U2 is electrically connected to pin 19MOTOR_EN of Bluetooth chip U1. When pin 19MOTOR_EN of Bluetooth chip U1 outputs a high-level signal, motor driver chip U2 enters an active state. When the base station enters low-power mode, pin 19MOTOR_EN of Bluetooth chip U1 outputs a low-level signal, and motor driver chip U2 enters a dormant state.

[0088] Pin 5IPROPI of motor driver chip U2 is electrically connected to pin 3MOTOR_ADC of Bluetooth chip U1 for current sampling. When the sampled current exceeds a certain threshold, pins 17MOTOR_PWM_P and 18MOTOR_PWM_N of Bluetooth chip U1 both output low-level signals, thereby stopping switching element motor 20. This prevents excessive stall current from burning out motor 20 in unusual situations (e.g., a stuck switch).

[0089] Pins 8VM and 4VREF of the motor driver chip U2 are electrically connected to the power supply. The input voltage of pin 8VM is 12V, which is used to drive the switching component motor 20 to work; the input voltage of pin 4VREF is 3.3V, which is used to power the motor driver chip U2 to work.

[0090] It should be noted that Figure 7 The switching motor control module 1031 is further provided with a first connector J1, which is electrically connected to the switching motor 20. The first connector J1 ensures smooth transmission of power and control signals, while providing a stable mechanical connection and necessary protection.

[0091] It should be noted that this application only shows one component composition of the switching element motor control module 1031, which does not mean that only this component composition can realize the function of the switching element motor control module 1031. Other components that can realize this function can also be replaced, and are not limited to this.

[0092] In one embodiment of the present application, Figure 8 As shown, the dust extraction motor control module 1032 includes a third switching device Q9, the control end of the third switching device Q9 is electrically connected to the wireless communication control module 101, the first conduction end of the third switching device Q9 is electrically connected to the dust extraction motor 30, and the second conduction end of the third switching device Q9 is grounded.

[0093] It should be noted that, in this embodiment, the control end of the third switch device Q9 serves as the input end of the dust extraction motor control module 1032 , and the first conduction end of the third switch device Q9 serves as the output end of the dust extraction motor control module 1032 .

[0094] Specifically, the third switch device Q9 is turned on or off according to the dust extraction motor drive signal output by pin 33AC_MOTOR_CTL of the Bluetooth chip U1, thereby controlling the operation or stop of the dust extraction motor 30. If the first switch device Q1 is a high-level conduction device, when the dust extraction motor drive signal is a high-level signal, the third switch device Q9 is turned on, and the dust extraction motor 30 operates. When the dust extraction motor drive signal is a low-level signal, the third switch device Q9 is turned off, and the dust extraction motor 30 does not operate. If the third switch device Q9 is a low-level conduction device, when the dust extraction motor drive signal is a high-level signal, the third switch device Q9 is turned off, and the dust extraction motor 30 does not operate. When the dust extraction motor drive signal is a low-level signal, the third switch device Q9 is turned on, and the dust extraction motor 30 operates.

[0095] It should be noted that the third switching device Q9 can be a third transistor, the base of the third transistor serves as the control end of the third switching device Q9, the collector of the third transistor serves as the first conduction end of the third switching device Q9, and the emitter of the third transistor serves as the second conduction end of the first switching device Q1.

[0096] Exemplarily, the third transistor may be an NPN transistor.

[0097] It should be noted that Figure 8The dust extraction motor control module 1032 is also provided with a second connector J2, and the second connector J2 is electrically connected to the dust extraction motor 30. The second connector J2 ensures the smooth transmission of electrical energy and control signals, while providing a stable mechanical connection and necessary protection. Pin 4 of the second connector J2 is electrically connected to pin 27SWDIO / ZERO_DET of the Bluetooth chip U1 for zero-crossing detection. The dust extraction motor 30 is started when the zero point of the AC power is detected, and the instantaneous current impact of the dust extraction motor 30 at startup is reduced to prevent the user from tripping the circuit when collecting dust. Pin 1 of the second connector J2 is connected to the power supply and inputs a 24V voltage to power the mainboard of the base station. Pin 1 of the second connector J2 is also connected to a transient suppression diode, which can suppress voltage transient impacts. When a transient high-voltage impact occurs in the circuit, the transient suppression diode can start quickly within a few nanoseconds or picoseconds, absorb the transient high energy, and thus protect the safety of the subsequent circuit.

[0098] It should be noted that this application only shows one component composition of the dust extraction motor control module 1032, which does not mean that only this component composition can realize the function of the dust extraction motor control module 1032. Other components that can realize this function can also be replaced, and are not limited to this.

[0099] In one embodiment of the present application, Figure 9 As shown, the base station control circuit 10 further includes a status detection module 104, which is electrically connected to the wireless communication control module 101 and is configured to detect base station status information. The status information includes at least one of motor status information, dust bag installation status information, flip cover closed status information, button status information, and water tank status information.

[0100] Specifically, the status detection module 104 can monitor the status of key components such as the motor, dust bag, flip cover, button, and water tank in real time, ensuring that the wireless communication control module 101 is aware of the working status of each component. Through the status detection module 104, the wireless communication control module 101 can quickly identify faults or abnormal conditions, such as motor overheating, dust bag not installed, flip cover not closed, button pressed, water tank lack of water, sewage tank full of water, or water tank or sewage tank not installed, etc., and can provide feedback to the user, allowing the user to promptly understand the working status of the base station, improving the user experience and the overall intelligence level. In addition, the wireless communication control module 101 can control each functional motor in real time based on the fault or abnormal status to ensure that the base station can perform smoothly.

[0101] In one embodiment of the present application, Figure 10As shown, the state detection module 104 further includes at least one of a micro switch, a photoelectric switch, a Hall sensor, and an infrared sensor. The micro switch, the photoelectric switch, the Hall sensor, and the infrared sensor are all detection devices.

[0102] Specifically, a micro switch is a contact sensor that is typically used to detect physical position or movement, such as when a switch is in place. When the physical condition being detected is met (e.g., when a switch is in place), the micro switch closes, and the status detection module 104 sends a corresponding signal to the wireless communication control module 101 via an electrical connection with the wireless communication control module 101, indicating that the component is in the expected state.

[0103] Photoelectric switches use the photoelectric effect to detect the presence of objects and are commonly used to detect dust or trash within base stations. When dust or trash blocks the light, the photoelectric switch turns off, and the status detection module 104 sends a corresponding signal to the wireless communication control module 101, indicating that the base station is full of dust or trash and needs to be cleaned or disposed of.

[0104] Hall effect sensors are non-contact sensors that detect changes in magnetic fields and are commonly used to monitor motor status, such as speed and direction. By detecting changes in the magnetic field generated by a motor, Hall effect sensors can provide accurate information about the motor's operating status. Alternatively, Hall effect sensors can be used to monitor the installation of fresh water and wastewater tanks in base stations.

[0105] The infrared sensor is used to determine the status of a component based on the detected infrared signal. In base station control, the infrared sensor can be used to detect whether the base station's flip cover is closed.

[0106] Exemplarily, when it is necessary to detect whether the switching element is in place (the switching element is driven by the switching element motor), a first detection device and a second detection device can be set on opposite sides of the switching element, wherein the first detection device is electrically connected to pin 22L_DET1 of the Bluetooth chip U1, and the second detection device is electrically connected to pin 24L_DET2 of the Bluetooth chip U1. When the first detection device is triggered, the switching element rotates to a position where the first dust collection channel is connected to the dust collection chamber, and the second dust collection channel is not connected to the dust collection chamber. At this time, the pin 22L_DET1 of the Bluetooth chip U1 can control the dust of the cleaning robot to be drawn into the dust collection chamber through the trigger signal input by the first detection device. When the second detection device is triggered, the switching element rotates to a position where the second dust collection channel is connected to the dust collection chamber, and the first dust collection channel is not connected to the dust collection chamber. At this time, the pin 24L_DET2 of the Bluetooth chip U1 can control the dust of the handheld vacuum cleaner to be drawn into the dust collection chamber through the trigger signal input by the second detection device.

[0107] For example, when the dust bag needs to be detected, the third detection device is electrically connected with the pin 28SWCLK / DUSTBAG_DET of the Bluetooth chip U1, for detecting whether the dust bag is installed in place, so that the Bluetooth chip U1 controls the dust in the cleaning robot and / or the handheld vacuum cleaner to be sucked into the dust bag of the dust collection cavity. For example, in an application scenario, during the process that the Bluetooth chip U1 controls the dust in the cleaning robot to be sucked into the dust bag of the dust collection cavity, if the third detection device switches from the triggered state to the untriggered state, i.e., it is detected that the dust bag is not installed in place, the Bluetooth chip U1 controls to stop the dust collection.

[0108] For example, when the flip cover needs to be detected, the fourth detection device is electrically connected with the pin 34BOX_COVER_HALL of the Bluetooth chip U1, for detecting whether the flip cover of the base station is closed.

[0109] It should be noted that the flip cover of the base station is for the user to open the flip cover and take out the disposable dust bag from the dust collection cavity for replacement. If the flip cover of the base station is not closed, it will affect the dust collection effect of the base station. Therefore, by detecting whether the flip cover of the base station is closed, the Bluetooth chip U1 can more effectively control the dust collection.

[0110] For example, when the pairing key needs to be detected, the fifth detection device is electrically connected with the pin 25MODE_KEY of the Bluetooth chip U1, for detecting whether the pairing key is triggered.

[0111] It should be noted that when the base station needs to be paired with the cleaning robot again, after the pairing key of the base station is triggered, the Bluetooth chip U1 receives the trigger signal and can be paired with the cleaning robot again.

[0112] In an embodiment of the present application, as shown in Figure 10 The state detection module 104 further includes a bidirectional TVS tube, one end of which is connected with the third connector J3 and the other end is grounded, so as to prevent static electricity from affecting the circuit.

[0113] It should be noted that the third connector J3 is used to connect the detection device.

[0114] It should be noted that only one element composition of the state detection module 104 is shown in the present application, which does not mean that only this element composition can realize the function of the state detection module 104. Other elements that can realize the function can also be replaced, and are not limited to this.

[0115] The present application also discloses a base station, which comprises the base station control circuit 10 and at least one functional motor, and the wireless communication control module in the base station control circuit 10 is the unique master control of the base station.

[0116] The present application also discloses a base station control system, comprising a cleaning robot and the above-mentioned base station. The base station control system uses the above-mentioned base station to communicate with the cleaning robot and cooperate with the cleaning robot to complete corresponding tasks.
