Typically, these cleaning devices are physically separate and have mutually exclusive components. This requires a significant investment to purchase multiple cleaning devices to meet different cleaning needs. Furthermore, these multiple cleaning devices occupy a significant amount of physical space, which can easily limit consumer demand.SUMMARY

[0025] The first cleaning device can be of various types, including a floor scrubber or a handheld vacuum cleaner. It can also be a sweeper-and-mop machine with both sweeping and mopping functions, which is not specifically limited herein.

[0026] In some embodiments, as shown in FIG. 3, the first cleaning device is a floor scrubber. The first cleaning device 800 includes a body 81, a sewage tank (not shown), and a floor brush (not shown).

[0029] In some embodiments, as shown in FIG. 5, the second cleaning device 900 includes a main body 91 and a dust collection cup 92 disposed within the main body 91. The dust collection cup 92 has an air inlet and an air outlet, and the air outlet of the dust collection cup 92 is detachably connected to the power module 100. The second cleaning device 900 can include an electric roller brush device connected to the air inlet of the dust collection cup 92. The second cleaning device 900 includes a second fluid flow path extending from the electric roller brush device to the dust collection cup 92. When the power module 100 is assembled on the second cleaning device 900, the power module 100 is pneumatically communicated to the second fluid flow path. The power module 100 supplies power to the electric roller brush device of the second cleaning device 900 via the power supply module 700.

[0030] In some embodiments, as shown in FIG. 6, the housing 200 is provided with a snap fastener 22, and the main body 91 is provided with an engagement slot 93. When the main body 91 is connected to the housing 200, the snap fastener 22 is secured within the engagement slot 93.

[0031] The driving source 300 is mounted on the housing 200 and is used to drive the target cleaning device to generate a negative vacuum pressure to extract external dirt. The driving source 300 can be of various types, such as a fan assembly, a vacuum pump, or other devices. The fan assembly can be an axial flow fan or a rotary fan, which is not specifically limited herein.

[0032] The first interactive assembly 400 is mounted on the housing 200 and is used to interact with the first cleaning device to obtain a first target mode signal. The first target mode signal instructs the controller 600 to select a first target operating mode to control the first cleaning device. The first target operating mode is an operating mode adapted for the first cleaning device. The first target operating mode includes a scrubber mode, a vacuuming mode, a sweeping mode, or a mopping mode, etc.

[0033] In some embodiments, as shown in FIG. 7, the first interactive assembly 400 includes a first communication interface 41, and the first communication interface 41 is electrically connected to the controller 600. The first cleaning device can transmit the first target mode signal to the power module 100 via the communication interface. The first communication interface 41 may support I2C, SPI, UART, RS232, RS422, RS485, TTL, or USB communication protocols.

[0034] In some embodiments, the first cleaning device is equipped with a first main controller and a first trigger circuit. The first main controller is electrically connected to the first trigger circuit based on the first communication interface 41. The first trigger circuit generates a first trigger command in response to a trigger operation. The first main controller then sends a first target mode signal to the first communication interface based on the first trigger command.

[0035] The first trigger circuit may be a key circuit, a touch screen circuit, a voice control circuit, or a visual trigger circuit, etc. When a user presses the key circuit, the key circuit generates the first trigger command. Alternatively, the touch screen circuit generates the first trigger command based on a touch operation of the user. Alternatively, the voice control circuit generates the first trigger command based on a voice input of the user. Alternatively, the visual trigger circuit generates the first trigger command based on an image of the user.

[0036] In some embodiments, the first cleaning device is equipped with a first main controller with logic analysis capabilities. When the first cleaning device is equipped with the power module, the first main controller is electrically connected to the first communication interface and transmits a first target mode signal to the first communication interface.

[0037] In some embodiments, the first cleaning device may not require a first main controller with logic analysis capabilities and may only require a first trigger circuit. When the first cleaning device is equipped with the power module, the first trigger circuit is electrically connected to the first communication interface, thereby triggering the first trigger circuit to generate a first target mode signal and transmit the first target mode signal to the first communication interface. For example, when the first cleaning device is equipped with the power module, the first trigger circuit is electrically connected to the first communication interface, forming a loop with the first trigger circuit and generating a voltage signal, and the voltage signal is transmitted to the first communication interface as the first target mode signal.

[0038] In some embodiments, the first cleaning device may not require a first main controller with logic analysis capabilities or a first trigger circuit. When the first cleaning device is equipped with the power module, the first cleaning device may update the first-type level signal on the first communication interface to a second-type level signal, and the second-type level signal serves as the first target mode signal. When the first cleaning device is not equipped with a power module, the level signal of the first communication interface remains at the first-type level signal.

[0039] In some embodiments, the first-type level signal is a high level signal, and the second-type level signal is a low level signal. Alternatively, the first-type level signal is a low level signal, and the second-type level signal is a high level signal.

[0040] In some embodiments, the first interactive assembly 400 includes a first wireless communication module, and the first cleaning device is equipped with a second wireless communication module. The first cleaning device can transmit a first target mode signal to the power module 100 via the second wireless communication module, and the power module 100 receives the first target mode signal based on the first wireless communication module. The first wireless communication module can be Bluetooth, Wi-Fi, Zigbee, NFC, RFID, infrared communication module, 4G, 5G, 6G, etc.

[0041] It is understood that the first target mode signal can be expressed as a high level or a low level, or as a data frame that meets the corresponding communication protocol.

[0042] The second interactive assembly 500 is mounted on the housing 200 and is used to interact with a person or a second cleaning device to obtain a second target mode signal. The second target mode signal is used to instruct the controller 600 to select a second target operating mode to control the second cleaning device. The second target operating mode is an operating mode adapted for the second cleaning device. The second target operating mode includes a scrubber mode, a vacuum mode, a sweeping mode, or a mopping mode, etc.

[0043] In some embodiments, as shown in FIG. 8 , the second interactive assembly 500 includes a key circuit 51. The key circuit 51 is mounted on the housing 200 and electrically connected to the controller 600 to generate the second target mode signal.

[0044] In some embodiments, the second target mode signal can be generated by the key circuit 51 in response to a user pressing operation. The second target mode signal can be a high level or a low level. That is, when the user presses the key circuit 51, the key circuit 51 generates a high level, which represents the second target mode signal. Alternatively, when the user presses the key circuit 51, the key circuit 51 generates a low level, which represents the second target mode signal.

[0045] As shown in FIG. 1, the housing 200 includes a handle 23, and the key circuit 51 is disposed on the handle 23. The user can hold the handle 23 and operate the key circuit 51 on the handle 23, which facilitates user operation.

[0046] In some embodiments, the second interactive assembly 500 includes a second communication interface electrically connected to the controller 600. The second communication interface can support any one of the aforementioned communication protocols.

[0047] In some embodiments, the second cleaning device may be equipped with both a second main controller and a second trigger circuit, or may be equipped with only a second main controller, or may be equipped with only a second trigger circuit, or may not require a second main controller with logic analysis capabilities and a second trigger circuit. It is understood that the description of the second main controller and the second trigger circuit can refer to the description of the first main controller and the first trigger circuit above, and which will not be repeated here.

[0048] In some embodiments, the second interactive assembly 500 includes a third wireless communication module, and the second cleaning device is equipped with a fourth wireless communication module. The second cleaning device can transmit a second target mode signal to the power module 100 via the fourth wireless communication module, and the power module 100 receives the second target mode signal based on the third wireless communication module.

[0049] It is understood that the second target mode signal can be expressed as a high level or a low level, or as a data frame that complies with the corresponding communication protocol.

[0050] The controller 600 is mounted on the housing and electrically connected to the driving source 300, the first interactive assembly 400, and the second interactive assembly 500. The controller 600 is configured to select a target operating mode based on the signal received by the first interactive assembly 400 to control the driving source 300 to perform a cleaning operation in conjunction with the target cleaning device. Alternatively, the controller 600 is configured to select a target operating mode based on the signal received by the second interactive assembly 500 to control the driving source 300 to perform a cleaning operation in conjunction with the target cleaning device. Alternatively, the controller 600 is configured to select a target operating mode based on the signal received by the first interactive assembly 400 and the second interactive assembly 500 to control the driving source 300 to perform a cleaning operation in conjunction with the target cleaning device. The controller 600 can be a single-chip microcomputer, a PWM control board, a microprocessor, or other processor.

[0051] The power supply module 700 is mounted on the housing 200 and electrically connected to the driving source 300, the first interactive assembly 400, the second interactive assembly 500, and the controller 600, which is configured to supply power.

[0052] The power supply module 700 can be of various types, including a nickel-cadmium battery, a lithium-ion battery, or a lead-acid battery, which is not specifically limited herein.

[0053] When a user needs to use the first cleaning device, the power module 100 is assembled to the first cleaning device. The controller 600 determines the target operating mode corresponding to the first cleaning device and sends a start signal to the power supply module 700. Upon receiving the start signal, the power supply module 700 supplies power to the driving source 300 and the first cleaning device. After the driving source 300 is activated, the controller 600 controls the driving source 300 to operate in conjunction with the first cleaning device according to the target operating mode.

[0054] When a user needs to use the second cleaning device, the power module 100 is first stopped , the power module 100 is then removed from the first cleaning device, and the power module 100 is then assembled to the second cleaning device. The controller 600 determines the target operating mode corresponding to the second cleaning device and sends a start signal to the power supply module 700. Upon receiving the start signal, the power supply module 700 supplies power to the driving source 300 and the second cleaning device. The controller 600 controls the driving source 300 to operate in conjunction with the second cleaning device according to the target operating mode.

[0055] The embodiment can drive different cleaning devices simultaneously, achieving a single power source for multiple uses. This can meet the diverse cleaning needs of the user and eliminate the need to purchase separate cleaning devices with mutually exclusive components, resulting in relatively cost savings and avoiding the issue of separate cleaning devices occupying relatively large physical spaces.

[0056] In some embodiments, the target operating mode includes a first target operating mode or a second target operating mode, where the first target operating mode is adapted for the first cleaning device, and the second target operating mode is adapted for the second cleaning device. The controller 600 is configured to determine whether the target cleaning device connected to the housing 200 is the first cleaning device or the second cleaning device based on signals received by the first interactive assembly 400 and / or the second interactive assembly 500, and then select the corresponding target operating mode.

[0057] It is understood that the embodiment can determine the target cleaning device and target operating mode based on the target mode signals received by each interactive assembly. In some embodiments, when the first interactive assembly 400 receives the first target mode signal, the controller 600 determines that the target cleaning device connected to the housing 200 is the first cleaning device based on the first target mode signal. In some embodiments, when the second interactive assembly 500 receives the second target mode signal, the controller 600 determines the target cleaning device connected to the housing 200 as the second cleaning device based on the second target mode signal.

[0058] It is also understood that the embodiment can combine the first target mode signal and the second target mode signal to determine the target cleaning device and target operating mode. This allows for multi-dimensional determination of the target cleaning device and target operating mode, thereby improving reliability.

[0059] In some embodiments, when the first interactive assembly 400 receives the first target mode signal, the controller 600 determines the target cleaning device connected to the housing 200 as the first cleaning device based on the first target mode signal and selects the first target operating mode to control the driving source 300 to perform a cleaning operation in conjunction with the first cleaning device.

[0060] For example, when the first interactive assembly 400 includes a first communication interface 41, the target cleaning device sends the first target mode signal to the first communication interface 41. The controller 600 determines the target cleaning device connected to the housing 200 as the first cleaning device based on the first target mode signal. Consequently, the target cleaning device can proactively initiate a handshake with the power module 100, allowing the power module 100 to quickly determine that the target cleaning device is the first cleaning device.

[0061] For another example, when the first interactive assembly 400 includes a first communication interface 41, the controller 600 sends a communication signal to the first communication interface 41 at a preset frequency. When the target cleaning device is assembled to the power module 100, the communication signal is transmitted to the main controller of the target cleaning device. The main controller sends a first target mode signal to the first communication interface 41 based on the communication signal. The controller 600 determines that the target cleaning device connected to the housing 200 is the first cleaning device based on the first target mode signal. Therefore, the power module 100 can proactively initiate a handshake, and the target cleaning device can actively exchange information with the power module 100 based on the communication signal, thereby reliably determining that the target cleaning device is the first cleaning device and avoiding misdetermination.

[0062] For another example, when the first interactive assembly 400 includes a first communication interface 41, a user operates the target cleaning device, such as by operating a trigger circuit of the target cleaning device, causing the target cleaning device to transmit a first target mode signal to the first communication interface 41. Based on the first target mode signal, the controller 600 determines that the target cleaning device connected to the housing 200 is the first cleaning device. Therefore, the power module 100 can re-determine the target cleaning device as the first cleaning device based on the user operation, thereby accommodating the user operation habits.

[0063] In some embodiments, when the first interactive assembly 400 does not receive the first target mode signal and the second interactive assembly 500 receives the second target mode signal, the controller 600 determines that the target cleaning device connected to the housing 200 is the second cleaning device based on the second target mode signal and selects the second target operating mode to control the driving source 300 to cooperate with the second cleaning device to perform a cleaning operation.

[0064] For example, when the first interactive assembly 400 includes a first communication interface 41 and the second interactive assembly 500 includes a key circuit 51; the controller 600 determines the target cleaning device connected to housing 200 as the second cleaning device based on the second target mode signal, and selects the second target operating mode to control driving source 300 to cooperate with the second cleaning device to perform a cleaning operation. Therefore, the embodiment can reliably determine that the target cleaning device is the second cleaning device by combining the first and second target mode signals, avoiding misdetermination.

[0065] In some embodiments, when the first interactive assembly 400 first receives the first target mode signal, the controller 600 further determines based on the first target mode signal whether the second interactive assembly 500 has received the second target mode signal. If it is determined that the second interactive assembly 500 has received the second target mode signal, the controller 600 shields the second target mode signal. If it is determined that the second interactive assembly 500 has not received the second target mode signal, the controller 600 controls the driving source 300 in the first target operating mode to perform a cleaning operation in conjunction with the first cleaning device.

[0066] For example, when the first interactive assembly 400 includes a first communication interface 41 and the second interactive assembly 500 includes a key circuit 51, when the target cleaning device is equipped with the power module 100 and a user presses a local key on the target cleaning device, the target cleaning device responds by sending a first target mode signal to the first communication interface 41. The controller 600, upon receiving the first target mode signal transmitted by the first communication interface 41, determines that the target cleaning device is a first cleaning device (e.g., a floor scrubber) and controls the driving source 300 to perform a cleaning operation in conjunction with the floor scrubber according to the first target operating mode (the floor scrubber mode). The controller 600 then determines whether the key circuit 51 has been pressed. If so, the key circuit 51 sends a second target mode signal to the controller 600, In order to prevent the second target mode signal from interfering with the controller 600 controlled in the floor scrubber mode, the controller 600 shields the second target mode signal. This ensures that the controller 600 can reliably, safely, and robustly control the driving source 300 to perform a cleaning operation in conjunction with the floor scrubber.

[0067] In some embodiments, when the second interactive assembly 500 first receives the second target mode signal, the controller 600 further determines whether the first interactive assembly 400 receives the first target mode signal based on the second target mode signal. If the first interactive assembly 400 receives the first target mode signal, the controller 600 shields the second target mode signal. If the first interactive assembly 400 does not receive the first target mode signal, the controller 600 controls the driving source 300 to cooperate with the second cleaning device to perform the cleaning operation according to the second target operating mode.

[0068] For example, when the first interactive assembly 400 includes a first communication interface 41 and the second interactive assembly 500 includes a key circuit 51, when the target cleaning device is equipped with the power module 100 and the user presses the key circuit 51 of the power module, the controller 600 receives the second target mode signal transmitted by the key circuit 51 and starts a timer to execute a timing operation. If the controller 600 determines within a preset time period that the first interactive assembly 400 has received the first target mode signal, the controller 600 shields the second target mode signal. In other words, the controller 600 does not directly determine that the target cleaning device is the second cleaning device (such as a vacuum cleaner) and does not control the driving source 300 to perform a cleaning operation in conjunction with the vacuum cleaner in the second target operating mode (vacuum cleaner mode). If the controller 600 determines within a preset time period that the first interactive assembly 400 has not received the first target mode signal, the controller 600 controls the driving source 300 in conjunction with the vacuum cleaner in the vacuum cleaner mode to perform a cleaning operation.

[0069] It is understandable that the first communication interface 41 is not in direct contact with the user and is not easily subject to misoperations by the user, that is, the first target mode signal obtained by the first communication interface 41 is capable of reliably reflecting whether the target cleaning device is the first cleaning device. When the first communication interface 41 receives the first target mode signal, the controller 600 can directly determine that the target cleaning device connected to the housing 200 is the first cleaning device, and select the first target operating mode to control the driving source 300 to cooperate with the first cleaning device to perform the cleaning operation. However, the key circuit 51 is arranged at the handle of the power module 100, exposed to the outside environment, and easily contacted with the user, and easily subject to erroneous triggering operations by the user. Therefore, when the controller 600 determines that the target cleaning device connected to the housing 200 is the first cleaning device, in order to avoid interference from the key circuit 51, the controller 600 selects to shield the second target mode signal sent by the key circuit 51.

[0070] When the controller 600 first receives the second target mode signal, it further determines within a preset time period whether the first interactive assembly 400 has received the first target mode signal. If the first interactive assembly 400 receives the first target mode signal within the preset time period, the controller 600 interprets the second target mode signal as a signal generated by an erroneous operation of user onto the key circuit 51 and, therefore, the controller 600 shields the second target mode signal. If the controller 600 determines within the preset time period that the first interactive assembly 400 has not received the first target mode signal, the controller 600 controls the driving source 300 to perform a cleaning operation in conjunction with the second cleaning device in accordance with the second target operating mode.

[0071] In some embodiments, when the second interactive assembly 500 receives the second target mode signal, the controller 600 determines, based on the second target mode signal, that the target cleaning device connected to the housing 200 is the second cleaning device and selects the second target operating mode to control the driving source 300 to perform a cleaning operation in conjunction with the second cleaning device. If the second interactive assembly 500 does not receive the second target mode signal, the controller 600 defaults to determining that the target cleaning device connected to the housing 200 is the first cleaning device and selects the first target operating mode to control the driving source 300 to perform cleaning operations in conjunction with the first cleaning device.

[0072] For example, if the first interactive assembly 400 includes the first communication interface 41 and the second interactive assembly 500 includes the key circuit 51, when the target cleaning device is assembled to the power module 100 and the user presses the key circuit 51 of the power module 100, the key circuit 51 receives the second target mode signal and transmits the second target mode signal to the controller 600. Based on the second target mode signal, the controller 600 determines that the target cleaning device connected to the housing 200 is a vacuum cleaner and selects the second target operating mode to control the driving source 300 to perform cleaning operations in conjunction with the vacuum cleaner.

[0073] If the user does not press the key circuit 51 of the power module 100 and the key circuit 51 does not receive the second target mode signal, the controller 600 defaults to determining that the target cleaning device connected to the housing 200 is a floor scrubber. In addition, the controller 600 sends a communication signal to the first communication interface 41 at a preset frequency. When the floor scrubber is equipped with the power module 100, the floor scrubber responds to the communication signal and feeds back a first target mode signal to the first communication interface, determining that the target cleaning device connected to the housing 200 is a floor scrubber, and then selects the floor scrubber mode to control the driving source 300 to cooperate with the floor scrubber to perform a cleaning operation.

[0074] In some embodiments, as shown in FIG. 9, the key circuit 51 includes a pull-up circuit 511 and a mode switch 512. The controller 600 electrically connects the pull-up circuit 511 and the mode switch 512 at a first node N1, respectively. When the mode switch 512 is pressed, the pull-up circuit 511 controls the first node N1 to output a first voltage signal. When the mode switch 512 is not pressed, the pull-up circuit 511 controls the first node N1 to output a second voltage signal. The first voltage signal is different from the second voltage signal and the first voltage signal is the second target mode signal.

[0075] In some embodiments, as shown in FIG. 10, the pull-up resistor 511 includes a resistor R1 and a resistor R2. One end of the resistor R1 and one end of the resistor R2 are both connected to an external power supply, where the external power supply is 5V. The other ends of the resistor R1 and the resistor R2 are both connected to a first node N1. One end of the mode switch 512 is connected to the first node N1, and the other end of the mode switch 512 is grounded. When the mode switch 512 is pressed, the first voltage signal at the first node N1 is a low level. When the mode switch 512 is not pressed, the second voltage signal at the first node N1 is a high level. The second target mode signal is a low level.

[0076] In some embodiments, as shown in FIG. 11, the key circuit 51 also includes a shift switch 513. The controller 600 is electrically connected to the pull-up circuit 511 and the shift switch 513 at a second node N2, respectively. The pressing operation of the shift switch 513 changes the voltage at the second node N2.

[0077] When the target operating mode is the first target operating mode, the controller 600 shields the voltage at the second node N2. For example, the first cleaning device is a floor scrubber, and the first target operating mode is floor scrubber mode. Since the floor scrubber has a gear shift function, the controller 600 can shield the signal generated by the gear shift switch on the power module 100 to prevent interference with the controller 600 controlling the floor scrubber. This improves the reliability and safety of the power module 100 in the floor scrubber mode.

[0078] When the target operating mode is the second target operating mode, the controller 600 adjusts the operating power of the driving source 300 in response to the voltage at the second node N2.

[0079] In some embodiments, when the target operating mode is the second target operating mode, the controller 600 calculates the operating power of the driving source 300 based on the number of times the voltage at the second node reaches a specified level and a preset power step size. The specified level can be a low level or a high level.

[0080] For example, if the second cleaning device is a vacuum cleaner and the second target operating mode is a vacuum cleaner mode, and the user presses the shift switch 513 twice, the voltage at the second node is the low level both times. The preset power step size is 5W. Therefore, the controller 600 calculates the operating power of the driving power 300 as 2*5=10W. Therefore, by providing a single shift switch 513, the embodiment enables arbitrary operating power adjustment, reducing structural design complexity and increasing power adjustment flexibility. Furthermore, the vacuum cleaner can utilize the shift switch 513 of the power module 100 to adjust its operating power, thereby simplifying the structural design of the vacuum cleaner.

[0081] In some embodiments, as shown in FIG. 10, one end of the shift switch 513 is connected to ground, and the other end of the shift switch 513 is connected to the second node N2. When the shift switch 513 is pressed, the voltage signal at the second node N2 is the low level. When the shift switch 513 is not pressed, the voltage signal at the second node N2 is the high level.

[0082] In some embodiments, as shown in FIG. 12, the power module 100 includes a display screen 24 mounted on the housing 200 and electrically connected to the controller 600. The display screen 24 is configured to display information corresponding to the first target operating mode or the second target operating mode. This information may be an icon, text, or lighting corresponding to the first target operating mode or the second target operating mode. This allows the user to understand the target operating mode of the power module 100 through the display screen 24, which facilitates user operation of the power module 100.

[0083] In some embodiments, when the first interactive assembly 400 includes a first communication interface 41, the first communication interface 41 is electrically connected to the controller 600. The controller 600 transmits a communication signal to the first cleaning device via the first communication interface 41 to detect whether the first cleaning device has responded with a first target mode signal based on the communication signal. When the controller 600 detects the first target mode signal, the controller 600 controls the power supply module 700 to supply power to the first cleaning device via the first communication interface 41.

[0084] In some embodiments, when the first cleaning device receives a communication signal, the first cleaning device verifies whether the communication signal is valid. If so, the first cleaning device returns a first target mode signal to the first communication interface 41. If not, the first cleaning device does not respond to the communication signal.

[0085] As shown in FIGS. 1 and 3, the housing 200 is provided with a first communication interface 41, and the body 81 is provided with a first device interface 83. When the body 81 is connected to the housing 200, the first device interface 83 is adapted to connect with the first communication interface 41. The first cleaning device can communicate with the controller 600 via the first device interface 83 and the first communication interface 41. Furthermore, the power supply module 700 can supply power to the first cleaning device via the first device interface 83 and the first communication interface 41.

[0086] As shown in FIGS. 1 and 4, the housing 200 is provided with a third communication interface 43, and the main body 91 is provided with a second device interface 94. When the main body 91 is connected to the housing 200, the second device interface 94 mates with the third communication interface 42. The second cleaning device can communicate with or charge the controller 600 via the second device interface 94 and the third communication interface 43. Furthermore, the power supply module 700 can supply power to the second cleaning device via the second device interface 94 and the third communication interface 43.

[0087] In some embodiments, as shown in FIG. 13, the power supply module 700 includes a battery 71, a first current branch 72, and a second current branch 73. The battery 71 is electrically connected to the first current branch 72 and the second current branch 73, respectively. The controller 600 is electrically connected to the first current branch 72 and the second current branch 73, respectively. In some embodiments, the power output terminal of the first current branch 72 is the first communication interface 41, and the power output terminal of the second current branch 73 is the third communication interface 43.

[0088] The battery 71 can be a lithium battery or a battery made of other materials. The first current branch 72 or the second current branch 73 can be a circuit structure with switching functions and current transmission, composed of various discrete components, including resistors, switches, capacitors, and other components.

[0089] When the target operating mode is the first target operating mode and the target cleaning device is the first cleaning device, the controller 600 switches on the first current branch 72 and disconnects the second current branch 73, thereby forming a first circuit with the battery 71, the first current branch 72, and the first cleaning device.

[0090] When the target operating mode is the second target operating mode and the target cleaning device is the second cleaning device, the controller 600 disconnects the first current branch 72 and switches on the second current branch 73, thereby forming a second circuit with the battery 71, the second current branch 73, and the second cleaning device. The power of the second cleaning device is less than that of the first cleaning device.

[0091] For example, when the first cleaning device is a floor scrubber and the first target operating mode is floor scrubber mode, the controller 600 enables the first current branch 72 and disconnects the second current branch 73, forming a first circuit between the battery 71, the first current branch 72, and the floor scrubber. When the second cleaning device is a vacuum cleaner and the second target operating mode is vacuum cleaner mode, the controller 600 disconnects first current branch 72 and enables the second current branch 73, forming a second circuit between the battery 71, the second current branch 73, and the vacuum cleaner. Because cleaning devices of varying power have different current or voltage load requirements for the current branches, this embodiment selectively enables the appropriate current branch to provide appropriate power to the respective cleaning device, thereby ensuring the operational safety of the power module.

[0092] In some embodiments, as shown in FIG. 14, the power supply module 700 further includes a sampling circuit 74, and the sampling circuit 74 is electrically connected to the first current branch 72 and the second current branch 73, respectively, for sampling a first electrical signal on the first circuit or a second electrical signal on the second circuit. The controller 600 is electrically connected to the sampling circuit 74 and is configured to determine the load type of the target cleaning device based on the target electrical signal and control the output power of the battery 71 based on the load type. The target electrical signal is either a first electrical signal or a second electrical signal.

[0093] The electrical signal can be a voltage signal or a current signal. The load type indicates the type of cleaning device equipped with the power module 100. When different cleaning devices are equipped with the power module, the cleaning devices can act as the load of the power module. The normal power of different cleaning devices can be the same or different. Generally, cleaning devices operating at normal power are more efficient and safer. This embodiment can provide a customized output power for the target cleaning device equipped with the power module 100 based on the load type, thereby improving the efficiency and safety of the target cleaning device.

[0094] In some embodiments, the controller 600 determines the load type of the target cleaning device based on the target electrical signal by obtaining a load type table, which includes multiple electrical signals and the load type corresponding to each electrical signal, and then traverses the load type table to determine the load type corresponding to the target electrical signal.

[0095] As another aspect of the present application, embodiments of the present application provide a cleaning system. The cleaning system includes a power module, a first cleaning device, and a second cleaning device. Either the first cleaning device or the second cleaning device is detachably connected to the power module. The embodiment can drive different cleaning devices to operate, achieving a single power source for multiple uses. This can meet diverse cleaning needs of the user and eliminate the need to purchase separate cleaning devices with mutually exclusive components, resulting in relatively cost-effectiveness and avoiding the issue of each independent cleaning device occupying a relatively large physical space.

[0096] As another aspect of an embodiment of the present application, an embodiment of the present application provides a method for controlling a cleaning device. As shown in FIG. 15, the method for controlling a cleaning device includes the following steps: S151: obtaining a first target mode signal via a first interactive assembly and a second target mode signal via a second interactive assembly. S152: selecting a target operating mode to control a driving source to cooperate with a target cleaning device to perform a cleaning operation based on signals obtained by the first interactive assembly and / or the second interactive assembly; and the target cleaning device is either the first cleaning device or the second cleaning device. S153: controlling a power supply module to supply power to the target cleaning device based on the target operating mode.

[0097] The embodiment can drive different cleaning devices, achieving a single power source for multiple uses. This can meet the diverse cleaning needs of the user and eliminate the need to purchase separate cleaning devices with mutually exclusive components, resulting in relatively cost savings and avoiding the issue of separate cleaning devices occupying relatively large physical spaces.

[0098] In some embodiments, the target operating mode includes a first target operating mode or a second target operating mode. The first target operating mode is adapted for a first cleaning device, and the second target operating mode is adapted for a second cleaning device. The step of selecting a target operating mode to control a driving source to cooperate with a target cleaning device to perform a cleaning operation based on signals obtained by the first interactive assembly and / or the second interactive assembly includes: determining, based on the signals received by the first interactive assembly and / or the second interactive assembly, whether the target cleaning device is the first cleaning device or the second cleaning device, and selecting the corresponding target operating mode to control the driving source to perform a cleaning operation with the target cleaning device.

[0099] In some embodiments, when the first interactive assembly receives the first target mode signal, it determines, based on the first target mode signal, that the target cleaning device is the first cleaning device, and selects the first target operating mode to control the driving source to perform a cleaning operation with the first cleaning device.

[0100] In some embodiments, when the first interactive assembly does not receive the first target mode signal and the second interactive assembly receives the second target mode signal, the target cleaning device is determined to be the second cleaning device based on the second target mode signal, and the second target operating mode is selected to control the driving source to cooperate with the second cleaning device to perform a cleaning operation.

[0101] In some embodiments, when the first interactive assembly first receives the first target mode signal, the first interactive assembly further determines whether the second interactive assembly has received the second target mode signal based on the first target mode signal. If the second interactive assembly determines that the second interactive assembly has received the second target mode signal, the second target mode signal is shielded. Alternatively, when the second interactive assembly first receives the second target mode signal, the second interactive assembly further determines whether the first interactive assembly has received the first target mode signal based on the second target mode signal. If the first interactive assembly determines that the first interactive assembly has received the first target mode signal, the second target mode signal is shielded.

[0102] In some embodiments, when the second interactive assembly receives the second target mode signal, the second interactive assembly determines that the target cleaning device is the second cleaning device based on the second target mode signal, and the second target operating mode is selected to control the driving source to cooperate with the second cleaning device to perform a cleaning operation. If the second interactive assembly does not receive the second target mode signal, it determines that the target cleaning device is the first cleaning device and selects the first target operating mode to control the driving source to cooperate with the first cleaning device to perform the cleaning operation.

[0002] The present application relates to the technical field of cleaning device technology, and more specifically to a power module and a cleaning system.BACKGROUND

[0003] With the advancement of cleaning device technology, a wide variety of cleaning devices have gradually become commonplace, providing various cleaning functions. For example, cleaning devices include floor scrubbers and vacuum cleaners, etc. People use different cleaning devices for different cleaning scenarios, such as a floor scrubber for cleaning floors and a small vacuum cleaner for cleaning tables. Typically, these cleaning devices are physically separate and have mutually exclusive components. This requires a significant investment to purchase multiple cleaning devices to meet different cleaning needs. Furthermore, these multiple cleaning devices occupy a significant amount of physical space, which can easily limit consumer demand.SUMMARY

[0025] The first cleaning device can be of various types, including a floor scrubber or a handheld vacuum cleaner. It can also be a sweeper-and-mop machine with both sweeping and mopping functions, which is not specifically limited herein.

[0026] In some embodiments, as shown in FIG. 3, the first cleaning device is a floor scrubber. The first cleaning device 800 includes a body 81, a sewage tank (not shown), and a floor brush (not shown). The sewage tank is detachably mounted on the body 81, and the floor brush is attached to a side of the body 81.

[0029] In some embodiments, as shown in FIG. 5, the second cleaning device 900 includes a main body 91 and a dust collection cup 92 disposed within the main body 91. The dust collection cup 92 has an air inlet and an air outlet, and the air outlet of the dust collection cup 92 is detachably connected to the power module 100. The second cleaning device 900 can include an electric roller brush device connected to the air inlet of the dust collection cup 92. The second cleaning device 900 includes a second fluid flow path extending from the electric roller brush device to the dust collection cup 92. When the power module 100 is assembled on the second cleaning device 900, the power module 100 is pneumatically communicated to the second fluid flow path. The power module 100 supplies power to the electric roller brush device of the second cleaning device 900 via the power supply module 700.

[0030] In some embodiments, as shown in FIG. 6, the housing 200 is provided with a snap fastener 22, and the main body 91 is provided with an engagement slot 93. When the main body 91 is connected to the housing 200, the snap fastener 22 is secured within the engagement slot 93.

[0031] The driving source 300 is mounted on the housing 200 and is used to drive the target cleaning device to generate a negative vacuum pressure to extract external dirt. The driving source 300 can be of various types, such as a fan assembly, a vacuum pump, or other devices. The fan assembly can be an axial flow fan or a rotary fan, which is not specifically limited herein.

[0032] The first interactive assembly 400 is mounted on the housing 200 and is used to interact with the first cleaning device to obtain a first target mode signal. The first target mode signal instructs the controller 600 to select a first target operating mode to control the first cleaning device. The first target operating mode is an operating mode adapted for the first cleaning device. The first target operating mode includes a scrubber mode, a vacuuming mode, a sweeping mode, or a mopping mode, etc.

[0033] In some embodiments, as shown in FIG. 7, the first interactive assembly 400 includes a first communication interface 41, and the first communication interface 41 is electrically connected to the controller 600. The first cleaning device can transmit the first target mode signal to the power module 100 via the communication interface. The first communication interface 41 may support I2C, SPI, UART, RS232, RS422, RS485, TTL, or USB communication protocols.

[0034] In some embodiments, the first cleaning device is equipped with a first main controller and a first trigger circuit. The first main controller is electrically connected to the first trigger circuit based on the first communication interface 41. The first trigger circuit generates a first trigger command in response to a trigger operation. The first main controller then sends a first target mode signal to the first communication interface based on the first trigger command.

[0035] The first trigger circuit may be a key circuit, a touch screen circuit, a voice control circuit, or a visual trigger circuit, etc. When a user presses the key circuit, the key circuit generates the first trigger command. Alternatively, the touch screen circuit generates the first trigger command based on a touch operation of the user. Alternatively, the voice control circuit generates the first trigger command based on a voice input of the user. Alternatively, the visual trigger circuit generates the first trigger command based on an image of the user.

[0036] In some embodiments, the first cleaning device is equipped with a first main controller with logic analysis capabilities. When the first cleaning device is equipped with the power module, the first main controller is electrically connected to the first communication interface and transmits a first target mode signal to the first communication interface.

[0037] In some embodiments, the first cleaning device may not require a first main controller with logic analysis capabilities and may only require a first trigger circuit. When the first cleaning device is equipped with the power module, the first trigger circuit is electrically connected to the first communication interface, thereby triggering the first trigger circuit to generate a first target mode signal and transmit the first target mode signal to the first communication interface. For example, when the first cleaning device is equipped with the power module, the first trigger circuit is electrically connected to the first communication interface, forming a loop with the first trigger circuit and generating a voltage signal, and the voltage signal is transmitted to the first communication interface as the first target mode signal.

[0038] In some embodiments, the first cleaning device may not require a first main controller with logic analysis capabilities or a first trigger circuit. When the first cleaning device is equipped with the power module, the first cleaning device may update the first-type level signal on the first communication interface to a second-type level signal, and the second-type level signal serves as the first target mode signal. When the first cleaning device is not equipped with a power module, the level signal of the first communication interface remains at the first-type level signal.

[0039] In some embodiments, the first-type level signal is a high level signal, and the second-type level signal is a low level signal. Alternatively, the first-type level signal is a low level signal, and the second-type level signal is a high level signal.

[0040] In some embodiments, the first interactive assembly 400 includes a first wireless communication module, and the first cleaning device is equipped with a second wireless communication module. The first cleaning device can transmit a first target mode signal to the power module 100 via the second wireless communication module, and the power module 100 receives the first target mode signal based on the first wireless communication module. The first wireless communication module can be Bluetooth, Wi-Fi, Zigbee, NFC, RFID, infrared communication module, 4G, 5G, 6G, etc.

[0041] It is understood that the first target mode signal can be expressed as a high level or a low level, or as a data frame that meets the corresponding communication protocol.

[0042] The second interactive assembly 500 is mounted on the housing 200 and is used to interact with a person or a second cleaning device to obtain a second target mode signal. The second target mode signal is used to instruct the controller 600 to select a second target operating mode to control the second cleaning device. The second target operating mode is an operating mode adapted for the second cleaning device. The second target operating mode includes a scrubber mode, a vacuum mode, a sweeping mode, or a mopping mode, etc.

[0043] In some embodiments, as shown in FIG. 8 , the second interactive assembly 500 includes a key circuit 51. The key circuit 51 is mounted on the housing 200 and electrically connected to the controller 600 to generate the second target mode signal.

[0044] In some embodiments, the second target mode signal can be generated by the key circuit 51 in response to a user pressing operation. The second target mode signal can be a high level or a low level. That is, when the user presses the key circuit 51, the key circuit 51 generates a high level, which represents the second target mode signal. Alternatively, when the user presses the key circuit 51, the key circuit 51 generates a low level, which represents the second target mode signal.

[0045] As shown in FIG. 1, the housing 200 includes a handle 23, and the key circuit 51 is disposed on the handle 23. The user can hold the handle 23 and operate the key circuit 51 on the handle 23, which facilitates user operation.

[0046] In some embodiments, the second interactive assembly 500 includes a second communication interface electrically connected to the controller 600. The second communication interface can support any one of the aforementioned communication protocols.

[0047] In some embodiments, the second cleaning device may be equipped with both a second main controller and a second trigger circuit, or may be equipped with only a second main controller, or may be equipped with only a second trigger circuit, or may not require a second main controller with logic analysis capabilities and a second trigger circuit. It is understood that the description of the second main controller and the second trigger circuit can refer to the description of the first main controller and the first trigger circuit above, and which will not be repeated here.

[0048] In some embodiments, the second interactive assembly 500 includes a third wireless communication module, and the second cleaning device is equipped with a fourth wireless communication module. The second cleaning device can transmit a second target mode signal to the power module 100 via the fourth wireless communication module, and the power module 100 receives the second target mode signal based on the third wireless communication module.

[0049] It is understood that the second target mode signal can be expressed as a high level or a low level, or as a data frame that complies with the corresponding communication protocol.

[0050] The controller 600 is mounted on the housing and electrically connected to the driving source 300, the first interactive assembly 400, and the second interactive assembly 500. The controller 600 is configured to select a target operating mode based on the signal received by the first interactive assembly 400 to control the driving source 300 to perform a cleaning operation in conjunction with the target cleaning device. Alternatively, the controller 600 is configured to select a target operating mode based on the signal received by the second interactive assembly 500 to control the driving source 300 to perform a cleaning operation in conjunction with the target cleaning device. Alternatively, the controller 600 is configured to select a target operating mode based on the signal received by the first interactive assembly 400 and the second interactive assembly 500 to control the driving source 300 to perform a cleaning operation in conjunction with the target cleaning device. The controller 600 can be a single-chip microcomputer, a PWM control board, a microprocessor, or other processor.

[0051] The power supply module 700 is mounted on the housing 200 and electrically connected to the driving source 300, the first interactive assembly 400, the second interactive assembly 500, and the controller 600, which is configured to supply power.

[0052] The power supply module 700 can be of various types, including a nickel-cadmium battery, a lithium-ion battery, or a lead-acid battery, which is not specifically limited herein.

[0053] When a user needs to use the first cleaning device, the power module 100 is assembled to the first cleaning device. The controller 600 determines the target operating mode corresponding to the first cleaning device and sends a start signal to the power supply module 700. Upon receiving the start signal, the power supply module 700 supplies power to the driving source 300 and the first cleaning device. After the driving source 300 is activated, the controller 600 controls the driving source 300 to operate in conjunction with the first cleaning device according to the target operating mode.

[0054] When a user needs to use the second cleaning device, the power module 100 is first stopped , the power module 100 is then removed from the first cleaning device, and the power module 100 is then assembled to the second cleaning device. The controller 600 determines the target operating mode corresponding to the second cleaning device and sends a start signal to the power supply module 700. Upon receiving the start signal, the power supply module 700 supplies power to the driving source 300 and the second cleaning device. The controller 600 controls the driving source 300 to operate in conjunction with the second cleaning device according to the target operating mode.

[0055] The embodiment can drive different cleaning devices simultaneously, achieving a single power source for multiple uses. This can meet the diverse cleaning needs of the user and eliminate the need to purchase separate cleaning devices with mutually exclusive components, resulting in relatively cost savings and avoiding the issue of separate cleaning devices occupying relatively large physical spaces.

[0056] In some embodiments, the target operating mode includes a first target operating mode or a second target operating mode, where the first target operating mode is adapted for the first cleaning device, and the second target operating mode is adapted for the second cleaning device. The controller 600 is configured to determine whether the target cleaning device connected to the housing 200 is the first cleaning device or the second cleaning device based on signals received by the first interactive assembly 400 and / or the second interactive assembly 500, and then select the corresponding target operating mode.

[0057] It is understood that the embodiment can determine the target cleaning device and target operating mode based on the target mode signals received by each interactive assembly. In some embodiments, when the first interactive assembly 400 receives the first target mode signal, the controller 600 determines that the target cleaning device connected to the housing 200 is the first cleaning device based on the first target mode signal. In some embodiments, when the second interactive assembly 500 receives the second target mode signal, the controller 600 determines the target cleaning device connected to the housing 200 as the second cleaning device based on the second target mode signal.

[0058] It is also understood that the embodiment can combine the first target mode signal and the second target mode signal to determine the target cleaning device and target operating mode. This allows for multi-dimensional determination of the target cleaning device and target operating mode, thereby improving reliability.

[0059] In some embodiments, when the first interactive assembly 400 receives the first target mode signal, the controller 600 determines the target cleaning device connected to the housing 200 as the first cleaning device based on the first target mode signal and selects the first target operating mode to control the driving source 300 to perform a cleaning operation in conjunction with the first cleaning device.

[0060] For example, when the first interactive assembly 400 includes a first communication interface 41, the target cleaning device sends the first target mode signal to the first communication interface 41. The controller 600 determines the target cleaning device connected to the housing 200 as the first cleaning device based on the first target mode signal. Consequently, the target cleaning device can proactively initiate a handshake with the power module 100, allowing the power module 100 to quickly determine that the target cleaning device is the first cleaning device.

[0061] For another example, when the first interactive assembly 400 includes a first communication interface 41, the controller 600 sends a communication signal to the first communication interface 41 at a preset frequency. When the target cleaning device is assembled to the power module 100, the communication signal is transmitted to the main controller of the target cleaning device. The main controller sends a first target mode signal to the first communication interface 41 based on the communication signal. The controller 600 determines that the target cleaning device connected to the housing 200 is the first cleaning device based on the first target mode signal. Therefore, the power module 100 can proactively initiate a handshake, and the target cleaning device can actively exchange information with the power module 100 based on the communication signal, thereby reliably determining that the target cleaning device is the first cleaning device and avoiding misdetermination.

[0062] For another example, when the first interactive assembly 400 includes a first communication interface 41, a user operates the target cleaning device, such as by operating a trigger circuit of the target cleaning device, causing the target cleaning device to transmit a first target mode signal to the first communication interface 41. Based on the first target mode signal, the controller 600 determines that the target cleaning device connected to the housing 200 is the first cleaning device. Therefore, the power module 100 can re-determine the target cleaning device as the first cleaning device based on the user operation, thereby accommodating the user operation habits.

[0063] In some embodiments, when the first interactive assembly 400 does not receive the first target mode signal and the second interactive assembly 500 receives the second target mode signal, the controller 600 determines that the target cleaning device connected to the housing 200 is the second cleaning device based on the second target mode signal and selects the second target operating mode to control the driving source 300 to cooperate with the second cleaning device to perform a cleaning operation.

[0064] For example, when the first interactive assembly 400 includes a first communication interface 41 and the second interactive assembly 500 includes a key circuit 51; the controller 600 determines the target cleaning device connected to housing 200 as the second cleaning device based on the second target mode signal, and selects the second target operating mode to control driving source 300 to cooperate with the second cleaning device to perform a cleaning operation. Therefore, the embodiment can reliably determine that the target cleaning device is the second cleaning device by combining the first and second target mode signals, avoiding misdetermination.

[0065] In some embodiments, when the first interactive assembly 400 first receives the first target mode signal, the controller 600 further determines based on the first target mode signal whether the second interactive assembly 500 has received the second target mode signal. If it is determined that the second interactive assembly 500 has received the second target mode signal, the controller 600 shields the second target mode signal. If it is determined that the second interactive assembly 500 has not received the second target mode signal, the controller 600 controls the driving source 300 in the first target operating mode to perform a cleaning operation in conjunction with the first cleaning device.

[0066] For example, when the first interactive assembly 400 includes a first communication interface 41 and the second interactive assembly 500 includes a key circuit 51, when the target cleaning device is equipped with the power module 100 and a user presses a local key on the target cleaning device, the target cleaning device responds by sending a first target mode signal to the first communication interface 41. The controller 600, upon receiving the first target mode signal transmitted by the first communication interface 41, determines that the target cleaning device is a first cleaning device (e.g., a floor scrubber) and controls the driving source 300 to perform a cleaning operation in conjunction with the floor scrubber according to the first target operating mode (the floor scrubber mode). The controller 600 then determines whether the key circuit 51 has been pressed. If so, the key circuit 51 sends a second target mode signal to the controller 600, In order to prevent the second target mode signal from interfering with the controller 600 controlled in the floor scrubber mode, the controller 600 shields the second target mode signal. This ensures that the controller 600 can reliably, safely, and robustly control the driving source 300 to perform a cleaning operation in conjunction with the floor scrubber.

[0067] In some embodiments, when the second interactive assembly 500 first receives the second target mode signal, the controller 600 further determines whether the first interactive assembly 400 receives the first target mode signal based on the second target mode signal. If the first interactive assembly 400 receives the first target mode signal, the controller 600 shields the second target mode signal. If the first interactive assembly 400 does not receive the first target mode signal, the controller 600 controls the driving source 300 to cooperate with the second cleaning device to perform the cleaning operation according to the second target operating mode.

[0068] For example, when the first interactive assembly 400 includes a first communication interface 41 and the second interactive assembly 500 includes a key circuit 51, when the target cleaning device is equipped with the power module 100 and the user presses the key circuit 51 of the power module, the controller 600 receives the second target mode signal transmitted by the key circuit 51 and starts a timer to execute a timing operation. If the controller 600 determines within a preset time period that the first interactive assembly 400 has received the first target mode signal, the controller 600 shields the second target mode signal. In other words, the controller 600 does not directly determine that the target cleaning device is the second cleaning device (such as a vacuum cleaner) and does not control the driving source 300 to perform a cleaning operation in conjunction with the vacuum cleaner in the second target operating mode (vacuum cleaner mode). If the controller 600 determines within a preset time period that the first interactive assembly 400 has not received the first target mode signal, the controller 600 controls the driving source 300 in conjunction with the vacuum cleaner in the vacuum cleaner mode to perform a cleaning operation.

[0069] It is understandable that the first communication interface 41 is not in direct contact with the user and is not easily subject to misoperations by the user, that is, the first target mode signal obtained by the first communication interface 41 is capable of reliably reflecting whether the target cleaning device is the first cleaning device. When the first communication interface 41 receives the first target mode signal, the controller 600 can directly determine that the target cleaning device connected to the housing 200 is the first cleaning device, and select the first target operating mode to control the driving source 300 to cooperate with the first cleaning device to perform the cleaning operation. However, the key circuit 51 is arranged at the handle of the power module 100, exposed to the outside environment, and easily contacted with the user, and easily subject to erroneous triggering operations by the user. Therefore, when the controller 600 determines that the target cleaning device connected to the housing 200 is the first cleaning device, in order to avoid interference from the key circuit 51, the controller 600 selects to shield the second target mode signal sent by the key circuit 51.

[0070] When the controller 600 first receives the second target mode signal, it further determines within a preset time period whether the first interactive assembly 400 has received the first target mode signal. If the first interactive assembly 400 receives the first target mode signal within the preset time period, the controller 600 interprets the second target mode signal as a signal generated by an erroneous operation of user onto the key circuit 51 and, therefore, the controller 600 shields the second target mode signal. If the controller 600 determines within the preset time period that the first interactive assembly 400 has not received the first target mode signal, the controller 600 controls the driving source 300 to perform a cleaning operation in conjunction with the second cleaning device in accordance with the second target operating mode.

[0071] In some embodiments, when the second interactive assembly 500 receives the second target mode signal, the controller 600 determines, based on the second target mode signal, that the target cleaning device connected to the housing 200 is the second cleaning device and selects the second target operating mode to control the driving source 300 to perform a cleaning operation in conjunction with the second cleaning device. If the second interactive assembly 500 does not receive the second target mode signal, the controller 600 defaults to determining that the target cleaning device connected to the housing 200 is the first cleaning device and selects the first target operating mode to control the driving source 300 to perform cleaning operations in conjunction with the first cleaning device.

[0072] For example, if the first interactive assembly 400 includes the first communication interface 41 and the second interactive assembly 500 includes the key circuit 51, when the target cleaning device is assembled to the power module 100 and the user presses the key circuit 51 of the power module 100, the key circuit 51 receives the second target mode signal and transmits the second target mode signal to the controller 600. Based on the second target mode signal, the controller 600 determines that the target cleaning device connected to the housing 200 is a vacuum cleaner and selects the second target operating mode to control the driving source 300 to perform cleaning operations in conjunction with the vacuum cleaner.

[0073] If the user does not press the key circuit 51 of the power module 100 and the key circuit 51 does not receive the second target mode signal, the controller 600 defaults to determining that the target cleaning device connected to the housing 200 is a floor scrubber. In addition, the controller 600 sends a communication signal to the first communication interface 41 at a preset frequency. When the floor scrubber is equipped with the power module 100, the floor scrubber responds to the communication signal and feeds back a first target mode signal to the first communication interface, determining that the target cleaning device connected to the housing 200 is a floor scrubber, and then selects the floor scrubber mode to control the driving source 300 to cooperate with the floor scrubber to perform a cleaning operation.

[0074] In some embodiments, as shown in FIG. 9, the key circuit 51 includes a pull-up circuit 511 and a mode switch 512. The controller 600 electrically connects the pull-up circuit 511 and the mode switch 512 at a first node N1, respectively. When the mode switch 512 is pressed, the pull-up circuit 511 controls the first node N1 to output a first voltage signal. When the mode switch 512 is not pressed, the pull-up circuit 511 controls the first node N1 to output a second voltage signal. The first voltage signal is different from the second voltage signal and the first voltage signal is the second target mode signal.

[0075] In some embodiments, as shown in FIG. 10, the pull-up resistor 511 includes a resistor R1 and a resistor R2. One end of the resistor R1 and one end of the resistor R2 are both connected to an external power supply, where the external power supply is 5V. The other ends of the resistor R1 and the resistor R2 are both connected to a first node N1. One end of the mode switch 512 is connected to the first node N1, and the other end of the mode switch 512 is grounded. When the mode switch 512 is pressed, the first voltage signal at the first node N1 is a low level. When the mode switch 512 is not pressed, the second voltage signal at the first node N1 is a high level. The second target mode signal is a low level.

[0076] In some embodiments, as shown in FIG. 11, the key circuit 51 also includes a shift switch 513. The controller 600 is electrically connected to the pull-up circuit 511 and the shift switch 513 at a second node N2, respectively. The pressing operation of the shift switch 513 changes the voltage at the second node N2.

[0077] When the target operating mode is the first target operating mode, the controller 600 shields the voltage at the second node N2. For example, the first cleaning device is a floor scrubber, and the first target operating mode is floor scrubber mode. Since the floor scrubber has a gear shift function, the controller 600 can shield the signal generated by the gear shift switch on the power module 100 to prevent interference with the controller 600 controlling the floor scrubber. This improves the reliability and safety of the power module 100 in the floor scrubber mode.

[0078] When the target operating mode is the second target operating mode, the controller 600 adjusts the operating power of the driving source 300 in response to the voltage at the second node N2.

[0079] In some embodiments, when the target operating mode is the second target operating mode, the controller 600 calculates the operating power of the driving source 300 based on the number of times the voltage at the second node reaches a specified level and a preset power step size. The specified level can be a low level or a high level.

[0080] For example, if the second cleaning device is a vacuum cleaner and the second target operating mode is a vacuum cleaner mode, and the user presses the shift switch 513 twice, the voltage at the second node is the low level both times. The preset power step size is 5W. Therefore, the controller 600 calculates the operating power of the driving power 300 as 2*5=10W. Therefore, by providing a single shift switch 513, the embodiment enables arbitrary operating power adjustment, reducing structural design complexity and increasing power adjustment flexibility. Furthermore, the vacuum cleaner can utilize the shift switch 513 of the power module 100 to adjust its operating power, thereby simplifying the structural design of the vacuum cleaner.

[0081] In some embodiments, as shown in FIG. 10, one end of the shift switch 513 is connected to ground, and the other end of the shift switch 513 is connected to the second node N2. When the shift switch 513 is pressed, the voltage signal at the second node N2 is the low level. When the shift switch 513 is not pressed, the voltage signal at the second node N2 is the high level.

[0082] In some embodiments, as shown in FIG. 12, the power module 100 includes a display screen 24 mounted on the housing 200 and electrically connected to the controller 600. The display screen 24 is configured to display information corresponding to the first target operating mode or the second target operating mode. This information may be an icon, text, or lighting corresponding to the first target operating mode or the second target operating mode. This allows the user to understand the target operating mode of the power module 100 through the display screen 24, which facilitates user operation of the power module 100.

[0083] In some embodiments, when the first interactive assembly 400 includes a first communication interface 41, the first communication interface 41 is electrically connected to the controller 600. The controller 600 transmits a communication signal to the first cleaning device via the first communication interface 41 to detect whether the first cleaning device has responded with a first target mode signal based on the communication signal. When the controller 600 detects the first target mode signal, the controller 600 controls the power supply module 700 to supply power to the first cleaning device via the first communication interface 41.

[0084] In some embodiments, when the first cleaning device receives a communication signal, the first cleaning device verifies whether the communication signal is valid. If so, the first cleaning device returns a first target mode signal to the first communication interface 41. If not, the first cleaning device does not respond to the communication signal.

[0085] As shown in FIGS. 1 and 3, the housing 200 is provided with a first communication interface 41, and the body 81 is provided with a first device interface 83. When the body 81 is connected to the housing 200, the first device interface 83 is adapted to connect with the first communication interface 41. The first cleaning device can communicate with the controller 600 via the first device interface 83 and the first communication interface 41. Furthermore, the power supply module 700 can supply power to the first cleaning device via the first device interface 83 and the first communication interface 41.

[0086] As shown in FIGS. 1 and 4, the housing 200 is provided with a third communication interface 43, and the main body 91 is provided with a second device interface 94. When the main body 91 is connected to the housing 200, the second device interface 94 mates with the third communication interface 42. The second cleaning device can communicate with or charge the controller 600 via the second device interface 94 and the third communication interface 43. Furthermore, the power supply module 700 can supply power to the second cleaning device via the second device interface 94 and the third communication interface 43.

[0087] In some embodiments, as shown in FIG. 13, the power supply module 700 includes a battery 71, a first current branch 72, and a second current branch 73. The battery 71 is electrically connected to the first current branch 72 and the second current branch 73, respectively. The controller 600 is electrically connected to the first current branch 72 and the second current branch 73, respectively. In some embodiments, the power output terminal of the first current branch 72 is the first communication interface 41, and the power output terminal of the second current branch 73 is the third communication interface 43.

[0088] The battery 71 can be a lithium battery or a battery made of other materials. The first current branch 72 or the second current branch 73 can be a circuit structure with switching functions and current transmission, composed of various discrete components, including resistors, switches, capacitors, and other components.

[0089] When the target operating mode is the first target operating mode and the target cleaning device is the first cleaning device, the controller 600 switches on the first current branch 72 and disconnects the second current branch 73, thereby forming a first circuit with the battery 71, the first current branch 72, and the first cleaning device.

[0090] When the target operating mode is the second target operating mode and the target cleaning device is the second cleaning device, the controller 600 disconnects the first current branch 72 and switches on the second current branch 73, thereby forming a second circuit with the battery 71, the second current branch 73, and the second cleaning device. The power of the second cleaning device is less than that of the first cleaning device.

[0091] For example, when the first cleaning device is a floor scrubber and the first target operating mode is floor scrubber mode, the controller 600 enables the first current branch 72 and disconnects the second current branch 73, forming a first circuit between the battery 71, the first current branch 72, and the floor scrubber. When the second cleaning device is a vacuum cleaner and the second target operating mode is vacuum cleaner mode, the controller 600 disconnects first current branch 72 and enables the second current branch 73, forming a second circuit between the battery 71, the second current branch 73, and the vacuum cleaner. Because cleaning devices of varying power have different current or voltage load requirements for the current branches, this embodiment selectively enables the appropriate current branch to provide appropriate power to the respective cleaning device, thereby ensuring the operational safety of the power module.

[0092] In some embodiments, as shown in FIG. 14, the power supply module 700 further includes a sampling circuit 74, and the sampling circuit 74 is electrically connected to the first current branch 72 and the second current branch 73, respectively, for sampling a first electrical signal on the first circuit or a second electrical signal on the second circuit. The controller 600 is electrically connected to the sampling circuit 74 and is configured to determine the load type of the target cleaning device based on the target electrical signal and control the output power of the battery 71 based on the load type. The target electrical signal is either a first electrical signal or a second electrical signal.

[0093] The electrical signal can be a voltage signal or a current signal. The load type indicates the type of cleaning device equipped with the power module 100. When different cleaning devices are equipped with the power module, the cleaning devices can act as the load of the power module. The normal power of different cleaning devices can be the same or different. Generally, cleaning devices operating at normal power are more efficient and safer. This embodiment can provide a customized output power for the target cleaning device equipped with the power module 100 based on the load type, thereby improving the efficiency and safety of the target cleaning device.

[0094] In some embodiments, the controller 600 determines the load type of the target cleaning device based on the target electrical signal by obtaining a load type table, which includes multiple electrical signals and the load type corresponding to each electrical signal, and then traverses the load type table to determine the load type corresponding to the target electrical signal.

[0095] As another aspect of the present application, embodiments of the present application provide a cleaning system. The cleaning system includes a power module, a first cleaning device, and a second cleaning device. Either the first cleaning device or the second cleaning device is detachably connected to the power module. The embodiment can drive different cleaning devices to operate, achieving a single power source for multiple uses. This can meet diverse cleaning needs of the user and eliminate the need to purchase separate cleaning devices with mutually exclusive components, resulting in relatively cost-effectiveness and avoiding the issue of each independent cleaning device occupying a relatively large physical space.

[0096] As another aspect of an embodiment of the present application, an embodiment of the present application provides a method for controlling a cleaning device. As shown in FIG. 15, the method for controlling a cleaning device includes the following steps: S151: obtaining a first target mode signal via a first interactive assembly and a second target mode signal via a second interactive assembly. S152: selecting a target operating mode to control a driving source to cooperate with a target cleaning device to perform a cleaning operation based on signals obtained by the first interactive assembly and / or the second interactive assembly; and the target cleaning device is either the first cleaning device or the second cleaning device. S153: controlling a power supply module to supply power to the target cleaning device based on the target operating mode.

[0097] The embodiment can drive different cleaning devices, achieving a single power source for multiple uses. This can meet the diverse cleaning needs of the user and eliminate the need to purchase separate cleaning devices with mutually exclusive components, resulting in relatively cost savings and avoiding the issue of separate cleaning devices occupying relatively large physical spaces.

[0098] In some embodiments, the target operating mode includes a first target operating mode or a second target operating mode. The first target operating mode is adapted for a first cleaning device, and the second target operating mode is adapted for a second cleaning device. The step of selecting a target operating mode to control a driving source to cooperate with a target cleaning device to perform a cleaning operation based on signals obtained by the first interactive assembly and / or the second interactive assembly includes: determining, based on the signals received by the first interactive assembly and / or the second interactive assembly, whether the target cleaning device is the first cleaning device or the second cleaning device, and selecting the corresponding target operating mode to control the driving source to perform a cleaning operation with the target cleaning device.

[0099] In some embodiments, when the first interactive assembly receives the first target mode signal, it determines, based on the first target mode signal, that the target cleaning device is the first cleaning device, and selects the first target operating mode to control the driving source to perform a cleaning operation with the first cleaning device.

[0100] In some embodiments, when the first interactive assembly does not receive the first target mode signal and the second interactive assembly receives the second target mode signal, the target cleaning device is determined to be the second cleaning device based on the second target mode signal, and the second target operating mode is selected to control the driving source to cooperate with the second cleaning device to perform a cleaning operation.

[0101] In some embodiments, when the first interactive assembly first receives the first target mode signal, the first interactive assembly further determines whether the second interactive assembly has received the second target mode signal based on the first target mode signal. If the second interactive assembly determines that the second interactive assembly has received the second target mode signal, the second target mode signal is shielded. Alternatively, when the second interactive assembly first receives the second target mode signal, the second interactive assembly further determines whether the first interactive assembly has received the first target mode signal based on the second target mode signal. If the first interactive assembly determines that the first interactive assembly has received the first target mode signal, the second target mode signal is shielded.

[0102] In some embodiments, when the second interactive assembly receives the second target mode signal, the second interactive assembly determines that the target cleaning device is the second cleaning device based on the second target mode signal, and the second target operating mode is selected to control the driving source to cooperate with the second cleaning device to perform a cleaning operation. If the second interactive assembly does not receive the second target mode signal, it determines that the target cleaning device is the first cleaning device and selects the first target operating mode to control the driving source to cooperate with the first cleaning device to perform the cleaning operation.
