[0024] To enable those skilled in the art to better understand the technical solutions in this disclosure, the technical solutions in the embodiments of this disclosure will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this disclosure, and not all embodiments. Based on the embodiments in this disclosure, all other embodiments obtained by those skilled in the art without creative effort should fall within the scope of protection of this disclosure.

[0025] Unless otherwise expressly stated, throughout the specification and claims, the term "comprising" or its variations such as "including" or "comprises" shall be understood to include the stated elements or components without excluding other elements or other components.

[0026] It should be noted that when an element is described as being "fixed to" another element, it can be directly attached to the other element or there may be an intervening element. When an element is considered to be "connected to" another element, it can be directly connected to the other element or there may be an intervening element.

[0027] Currently, vacuum cleaner products are continuously expanding their functional boundaries to adapt to diverse cleaning scenarios, and floor cleaning attachments integrating wet cleaning capabilities have become an important market development trend. However, the supporting after-sales maintenance technology, especially drying solutions, still has significant shortcomings, becoming a key factor restricting the improvement of user experience and the guarantee of product safety.

[0028] The shortcomings of existing floor cleaning accessory drying technologies are mainly reflected in the following aspects: First, the system's collaborative interactivity is poor. There is a lack of intelligent collaborative working mode between the floor cleaning accessory and the drying base. The interaction logic design is simple, failing to achieve fully automated control and resulting in a poor user experience. Second, the core temperature control accuracy is low. Traditional heating and drying systems often employ simple on / off temperature control strategies, making it difficult to avoid problems such as localized overheating and uneven drying, thus posing certain safety hazards. Third, the safety redundancy design is inadequate. Related protection mechanisms have shortcomings, lacking multi-level, redundant overheat protection measures. A single point failure in the temperature control system can easily lead to safety risks. These various shortcomings interact and collectively restrict the functionality of floor cleaning accessories, reducing the overall market competitiveness of the products.

[0029] Based on the above understanding, the technical implementation idea of ​​this disclosure is to construct a master-slave collaborative working mechanism between the cleaning base station and the cleaning equipment. When the communication connection between the cleaning equipment and the cleaning base station is interrupted, the cleaning base station will automatically terminate the drying process, thus ensuring the safety and intelligence of the cleaning base station during use.

[0030] Please refer to Figure 1 As shown, this application provides a control method for a clean base station, specifically including:

[0031] S1, when the cleaning equipment is connected to the cleaning base station and communication is established, responds to the drying command sent by the cleaning accessory and controls the cleaning base station to enter the drying mode to dry the cleaning accessory.

[0032] S2, in response to a communication interruption between the cleaning accessory and the cleaning base station, controls the cleaning base station to exit the drying mode.

[0033] Please refer to Figure 2 As shown, the cleaning base station 100 in this application is used to adapt to the cleaning device 200. The cleaning device 200 includes a battery accessory 201, a main control board 202, and a cleaning accessory 203. The cleaning base station 200 may have a receiving cavity or base for accommodating the cleaning accessory 203. The cleaning base station 100 is used to dry the cleaning accessory 203 of the cleaning device by heating and blowing in the drying mode.

[0034] The cleaning device 200 can be a cleaning device that combines floor washing and vacuuming functions. The floor washing and vacuuming functions can be switched by changing the cleaning attachment 203. In another embodiment, the cleaning device 200 can also include a separate floor scrubber, both of which can achieve the effects of this embodiment. Furthermore, the cleaning base station 100 in this application can also have multiple common base station functions such as docking, dust collection, and accessory storage.

[0035] Please combine Figure 3 As shown, step S1 further includes:

[0036] S11, after the cleaning equipment is connected to the cleaning base station, in response to the self-cleaning command, the cleaning base station is controlled to output a wake-up pulse sequence, wherein the wake-up pulse sequence is used to control the battery accessory 201, thereby driving the cleaning accessory 203 to power on, and the cleaning accessory 203 establishes communication with the cleaning base station after power-on.

[0037] S12, in response to the drying command sent by the cleaning accessory, controls the cleaning base station to enter the drying mode.

[0038] Please combine Figure 2 and Figure 4 As shown, the cleaning base station 100 in one embodiment also includes a power board 10, a button assembly 13, a temperature acquisition assembly 12, a heating assembly 14, and a heat dissipation assembly 11. The controller 500 is integrated on the power board 10. The power board 10 also integrates a power interface 101, a first interface 105, a second interface 103, a third interface 106, a fourth interface 102, and a fifth interface 104.

[0039] The cleaning base station 100 is connected to an AC power source via a power interface 101. The AC power source for the cleaning base station 100 can be mains power. After being powered on, the cleaning base station 100 enters standby mode. The cleaning base station 100 is connected to the cleaning device 200 via a first interface 105, to the temperature acquisition component 12 via a second interface 103, to the heating component 14 via a third interface 106, to the heat dissipation component 11 via a fourth interface 102, and to the button component 13 via a fifth interface 104.

[0040] The cleaning base station 100 has a drying area, which in this application can be a receiving cavity or base for accommodating the cleaning accessory 203. Furthermore, the temperature acquisition component 12, the heating component 14, and the heat dissipation component 11 are all disposed within the drying area.

[0041] Furthermore, in this embodiment, the cleaning base station 100 can charge the cleaning device 200. When the cleaning device 200 is paired with the cleaning base station 100, even if communication between the two is not established, the cleaning base station 100 can directly charge the battery accessory 201 in the cleaning device 200. Figure 3 As shown, when the cleaning equipment 200 is connected to the cleaning base station 100, the first switch K1, the second switch K2 and the third switch K3 are automatically closed.

[0042] When the user triggers the button component 13, the controller generates a corresponding self-cleaning command. In response to the self-cleaning command, the controller controls the cleaning base station 100 to output a wake-up pulse sequence through the first interface 105.

[0043] Specifically, in one embodiment, the cleaning base station 100 generates a specific wake-up pulse sequence through its internally designed dedicated pulse circuit, and outputs this wake-up pulse sequence through the power line in the first interface. Based on specific parameters or combinations thereof, such as level, phase, pulse width, period, and number of pulses in the wake-up pulse sequence, it ensures that only the placement of legitimate cleaning equipment 200 and its accessories can activate the cleaning base station 100. Combined with... Figure 3 As shown, when the battery accessory 201 of the cleaning device 200 receives an accurate wake-up pulse sequence, the fourth switch K4 and the fifth switch K5 automatically close, that is, the main control board and the cleaning accessory 203 are powered on. After being powered on, the cleaning accessory 203 establishes communication with the cleaning base station 100 (the cleaning accessory 203 communicates with the cleaning base station 100 through the second communication line COM2, and the cleaning accessory 203 communicates with the main control board 202 through the first communication line COM1). The two parties exchange status information based on a custom communication protocol and officially enter the self-cleaning and drying process.

[0044] Furthermore, step S2 specifically includes:

[0045] S21 monitors the communication status in real time and, in response to a communication interruption between the cleaning accessory and the cleaning base station, controls the cleaning base station to exit the drying mode.

[0046] If the communication interruption between the cleaning accessory 203 and the cleaning base station 100 lasts for more than a set threshold, the cleaning base station 100 is controlled to exit the drying mode, wherein the set threshold is greater than or equal to 1 second. For example, when the cleaning accessory 203 is removed, if the communication interruption between the cleaning accessory 203 and the cleaning base station 100 exceeds 3 seconds, the cleaning base station 100 automatically terminates the drying process.

[0047] This application employs a master-slave architecture, with the cleaning accessory 203 as the master and the cleaning base station 100 as the slave. Through a clearly defined communication protocol and status handshake process, the security and intelligence of the cleaning base station 100 during use are ensured. Specifically, the cleaning accessory 203 is responsible for initiating self-cleaning commands (including starting the drying mode and controlling the drying time), while the cleaning base station 100, as the slave, only executes authorized operations, avoiding the risk of accidental triggering. The communication protocol clearly defines the data interaction specifications between the two parties, covering key information such as device status (e.g., base station temperature, heat dissipation component 11 operating conditions) and command feedback, ensuring accurate and error-free command transmission. The status handshake process is implemented through real-time bidirectional verification, proceeding to the next step only after confirmation. This architecture allows the cleaning accessory 203 to monitor the slave's operating status in real time, and user operation of the cleaning base station 100 is limited to "one-click" start, making the operation of the cleaning base station 100 more convenient and reliable, comprehensively improving its security and intelligence.

[0048] Furthermore, the control method in one embodiment also includes: S22, real-time monitoring of the temperature of the drying zone.

[0049] Specifically, after the cleaning base station 100 enters the drying mode, the temperature acquisition component 12 samples the temperature of the drying area and compares the sampled temperature with a first temperature threshold. For example, the cleaning base station 100 uses a negative temperature coefficient (NTC) thermistor to monitor the temperature of the drying area in real time. The controller reads the voltage value of the NTC through an ADC (analog-to-digital converter) and calculates the accurate sampled temperature based on its resistance-temperature characteristic curve.

[0050] In one implementation, when the sampling temperature is less than a first temperature threshold, the control method includes:

[0051] S231a, when the sampling temperature is less than the first temperature threshold, the heating component 14 and the heat dissipation component 11 are controlled to work so that the temperature of the drying area changes to the target temperature, wherein the target temperature is less than the first temperature threshold.

[0052] Furthermore, the drying mode in this application specifically includes controlling the operation of the heating component 14 and the heat dissipation component 11 to change the temperature of the drying area to the target temperature. The heat dissipation component 11 is used for air blowing, meaning that the drying mode in this application involves simultaneous heating and air blowing. For example, the heat dissipation component 11 may include a fan.

[0053] In the existing technology, the basic drying function of the cleaning base station 100 is insufficient. The cleaning accessory 203 lacks an efficient and thorough drying mechanism after use. Residual moisture can easily breed bacteria and produce odors in the closed space, which not only affects the hygiene of use, but also greatly reduces the user's willingness to use it.

[0054] This application employs a technology that combines heating and blowing simultaneously. Its core principle is to utilize the principle of thermal convection to adapt to the enclosed chamber and multi-component splicing structure of the floor scrubber, thereby overcoming the shortcomings of a single drying method and achieving efficient and uniform drying results. At the same time, it protects the accessories and improves the user experience, making it the optimal drying solution for addressing the pain points of using floor scrubbers and other cleaning equipment.

[0055] When the heating component 14 and the heat dissipation component 11 work simultaneously, the heating provides vaporization energy to the deep moisture in the brush fibers, gaps, and rubber strip adhesion areas, allowing the moisture to quickly turn into water vapor. The airflow creates forced thermal convection, promptly expelling the water vapor from the chamber. Simultaneously, it allows hot air to evenly penetrate all parts of the brush, significantly improving drying efficiency and shortening drying time. This method achieves thorough drying without dead angles, avoiding localized stuffiness and dampness or deep moisture residue, thus eliminating mold growth, brush odor, and dirt buildup at the source. At the same time, the airflow removes some excess heat, keeping the temperature within the drying area as close to the target range as possible. This prevents high-temperature damage such as brittle brushes, aging rubber strips, and deformation of the plastic chamber, and also prevents metal bearings from rusting due to prolonged moisture, effectively extending the service life of all brush components.

[0056] Furthermore, in one embodiment, the heating component 14 includes a PTC heater with self-limiting temperature characteristics. That is, when the temperature reaches a preset high-temperature zone, the resistance of the PTC heater remains high, the current in the circuit decreases significantly, and the heat generation power drops sharply. At this point, the heat generation power of the PTC heater is approximately equal to the heat dissipation power, and the temperature no longer continues to rise, stabilizing in a specific range near the Curie temperature, which can serve as primary safety protection. Furthermore, structurally, the PTC heater uses mica sheets as insulation and support frames, with heating wires wound around them to ensure uniform heating and electrical safety.

[0057] The clean base station 100 also includes a drive circuit, wherein the drive circuit includes a zero-crossing detection circuit and the drive circuit uses at least two bidirectional thyristor switches as power switches.

[0058] The zero-crossing detection circuit is used to detect the zero-crossing point of the AC power supply. The controller generates a PWM signal based on the zero-crossing point of the AC power supply and adjusts the duty cycle of the PWM signal according to the difference between the sampled temperature and the target temperature. One bidirectional SCR switch is connected between the zero-crossing detection circuit and the heating component 14, and the other bidirectional SCR switch is connected between the zero-crossing detection circuit and the heat dissipation component 11. The bidirectional SCR switches are controlled by the PWM signal to control their own on / off state.

[0059] Understandably, the bidirectional thyristor switch conducts when the PWM signal is high, and the heating component 14 and the heat dissipation component 11 operate when the bidirectional thyristor switch is on. The controller dynamically controls the duty cycle of the PWM signal to adjust the on-time of the bidirectional thyristor switch, thereby controlling the power of the heating component 14 and the heat dissipation component 11, and achieving precise control of the temperature of the drying area.

[0060] This application utilizes a zero-crossing detection circuit to ensure that the bidirectional thyristor switch only conducts near the zero-crossing point of the AC voltage, thereby minimizing inrush current and electromagnetic interference (EMI), ensuring stable operation of the clean base station 100, significantly improving the reliability of the clean base station 100, and extending component life. Furthermore, the heating component 14 in this application is a resistive heating device, avoiding the electromagnetic interference generated by the switching on and off of the bidirectional thyristor switch, further reducing the impact of electromagnetic interference.

[0061] It is understood that zero-crossing detection circuits are well known in the prior art, so their working principle will not be described in detail here, and any known or unknown zero-crossing detection circuit can be used without restriction.

[0062] In typical control schemes, the target temperature is usually set as a safety threshold. Exceeding the target temperature triggers safety protection, while drying continues below it. The drawback of this scheme is the lack of redundant control time, making it prone to triggering safety protection even when the system is under control, thus reducing user experience. This application addresses this by setting an independent first temperature threshold (with the target temperature below this threshold) in addition to the target temperature, ensuring that the cleaning base station 100 can automatically adjust its temperature while maintaining safety.

[0063] For example, in one embodiment, the target temperature is 75~80°C and the first temperature threshold is 83°C. When the sampling temperature is less than the first temperature threshold, it indicates that the temperature of the drying area is still within a controllable range.

[0064] In one implementation, the cleaning base station, in drying mode, dynamically adjusts the sampling temperature to a reasonable range by adjusting the duty cycle of the heater and the duty cycle of the cooling fan, without immediately triggering safety protection, thus improving the user experience.

[0065] In another embodiment, in the drying mode, the duty cycle of the cooling fan (i.e., the ratio of the actual speed to the rated maximum speed) of the cleaning base station is fixed at 100%, and the duty cycle of the heater (i.e., the ratio of the actual output power to the rated maximum power) is negatively correlated with the sampling temperature. Based on the difference between the sampling temperature and the target temperature, the duty cycle of the heater is negatively fed back to adjust the sampling temperature in real time and bring it within a reasonable range.

[0066] Existing drying solutions suffer from insufficient energy efficiency management, generally failing to dynamically adjust power based on real-time temperature requirements. Heating systems often operate at a fixed power, leading to unnecessary energy waste. This application, however, uses an NTC sensor to collect real-time temperature data from the drying zone and, combined with a feedback control algorithm, dynamically adjusts the duty cycle of the heater and cooling fan. This achieves and maintains a stable and efficient drying temperature, overcoming the low drying efficiency or overheating risks associated with traditional drying devices due to their inefficient temperature control.

[0067] S232a: After the cleaning base station has been running for a preset drying time, it will automatically exit the drying mode.

[0068] S233a, In drying mode, the cleaning base station continuously monitors and judges the communication status between the cleaning accessory and the cleaning base station: if the communication between the cleaning accessory and the cleaning base station is interrupted, the drying mode is exited; if the communication between the cleaning accessory and the cleaning base station is not interrupted, the temperature of the drying area is continuously monitored.

[0069] Experimental results demonstrate that this application achieves precise temperature control of ±1℃, a four-fold improvement in accuracy compared to the traditional ±5℃ control. The intelligent power adjustment strategy based on real-time temperature feedback increases drying efficiency by 40% and reduces energy consumption by over 30%. The application of zero-crossing triggering technology effectively suppresses surge current and electromagnetic interference, extending the electrical lifespan of key power devices by 50%.

[0070] In another embodiment, when the sampling temperature is greater than or equal to a first temperature threshold, the control method includes:

[0071] S231b, when the sampled temperature is greater than or equal to the first temperature threshold, the heating component 14 is controlled to stop working.

[0072] The first level of protection in this application adopts a software active protection mechanism, which immediately triggers the shutdown of the heating component 14 when the sampled temperature reaches the first temperature threshold.

[0073] It should be noted that the drying mode in this application specifically includes controlling the operation of the heating component 14 and the heat dissipation component 11 to change the temperature of the drying area to the target temperature. The heat dissipation component 11 is used for air blowing, meaning that the drying mode in this application involves simultaneous heating and air blowing. When the heating component 14 stops working, the cleaning base station 100 exits the drying mode. Therefore, when the sampling temperature is greater than or equal to the first temperature threshold, the cleaning base station 100 automatically exits the drying mode.

[0074] In one embodiment, the operating mode of the cleaning base station 100 after exiting the drying mode includes: controlling the heat dissipation component 11 to keep blowing air to dissipate residual heat from the drying area, and controlling the heat dissipation component 11 to stop blowing air after the temperature of the drying area drops to a reasonable temperature value (i.e. until the sampling temperature is less than or equal to the third temperature threshold).

[0075] In another alternative embodiment, the operating mode of the cleaning base station 100 after exiting the drying mode includes: directly controlling the heating component 14 and the heat dissipation component 11 to stop working simultaneously, so that the drying area stops heating and airflow supply, and the drying area naturally returns to the ambient temperature.

[0076] S232b: When the sampled temperature is continuously greater than or equal to the first temperature threshold within a set time, the heating component 14 is powered off.

[0077] The second-level protection in this application adopts a hardware active protection mechanism. In the event of software protection failure or controller malfunction, the circuit can be physically disconnected to de-energize the heating component 14. At this time, the cleaning base station 100 will also automatically exit the drying mode. Furthermore, the second-level protection mechanism is resettable and can automatically recover after the fault is cleared. That is, when the sampled temperature is lower than the first temperature threshold, the heating component 14 can automatically power on (it should be noted that powering on does not mean starting to work).

[0078] Specifically, the clean base station 100 also includes a thermal protector connected between the heating component 14 and the power supply of the heating component 14; the thermal protector is configured to: turn off when the sampling temperature collected by the temperature acquisition component 12 is continuously greater than or equal to a first temperature threshold within a set time, and turn on when the sampling temperature is less than the first temperature threshold.

[0079] S233b, when the sampling temperature is greater than or equal to the second temperature threshold, the cleaning base station 100 is controlled to cut off the power supply to the whole machine, wherein the second temperature threshold is greater than the first temperature threshold.

[0080] The third level of protection in this application adopts a hardware passive protection mechanism: in extreme cases, if all the above protections fail and the temperature continues to rise to an unacceptable level, the power supply to the clean base station 100 will be completely cut off to eliminate any fire risk.

[0081] Specifically, the clean base station 100 includes a non-resettable thermal fuse connected between the clean base station 100 and its power supply; the thermal fuse is configured to permanently melt when the sampling temperature acquired by the temperature acquisition component 12 is greater than or equal to a second temperature threshold.

[0082] To further ensure absolute safety, this application constructs a three-tiered protection system consisting of software protection, a resettable thermal protector, and a non-resettable thermal fuse. This multi-redundancy design, combining software and hardware, active and passive approaches, ensures reliable protection under various abnormal conditions, minimizing risks even in extreme situations and fundamentally eliminating overheating risks. The control method in this application also features real-time status monitoring and fault self-diagnosis capabilities, further enhancing maintenance convenience.

[0083] Furthermore, the control method also includes: after the cleaning base station 100 exits the drying mode, controlling the heat dissipation component 11 to continue working until the sampling temperature is less than or equal to a third temperature threshold, wherein the third temperature threshold is less than the target temperature. For example, the third temperature threshold is 45°C.

[0084] Specifically, after the cleaning base station 100 enters the drying mode, the temperature acquisition component 12 is controlled to sample the temperature of the drying area and compare the sampled temperature with a third temperature threshold: when the sampled temperature is greater than or equal to the third temperature threshold, the heat dissipation component 11 is controlled to work; when the sampled temperature is less than the third temperature threshold, the heat dissipation component 11 is controlled to stop working.

[0085] As can be seen from the above, the reasons why the cleaning base station 100 exits the drying mode include: automatically exiting the drying mode after running the preset drying time; communication interruption; power failure of the heating component 14; and the heating component 14 stopping operation. All of the above reasons may result in residual heat in the drying area.

[0086] This application utilizes the residual heat dissipation method of continuous airflow from the heat dissipation component 11 to quickly remove residual heat from the drying area after the heating components have stopped operating. This prevents localized heat accumulation and avoids persistently high temperatures in the drying area, achieving uniform cooling. It also prevents residual high temperatures from continuously damaging plastic, rubber parts, filters, and other components, reducing thermal aging and extending the lifespan of the equipment and consumables. Furthermore, it avoids electronic component malfunctions and battery charging safety hazards caused by high temperatures. In addition, this design prevents small amounts of water from rapidly drying and forming scale at high temperatures, inhibiting the growth of mold and odors, and reducing cleaning and maintenance costs. Most importantly, it eliminates the risk of burns during other operations, ensuring stable equipment operation and safe use.

[0087] Please refer to Figure 5 As shown in the illustration, this application also provides a controller 500 for a cleaning base station 100.

[0088] In the embodiments of this specification, the cleaning base station 100 can be adapted to cleaning devices 200 including but not limited to vacuum cleaners, robotic vacuum cleaners, floor scrubbers, sweeping trucks, cleaning machines, and floor brushers. The cleaning base station 100 has the aforementioned beneficial effects, enabling the establishment of a master-slave collaborative working mechanism between the cleaning base station 100 and the cleaning devices 200. When the communication connection between the cleaning devices 200 and the cleaning base station 100 is interrupted, the cleaning base station 100 automatically terminates the drying process, ensuring the safety and intelligence of the cleaning base station 100 during use.

[0089] In one embodiment, the cleaning base station 100 further includes a power board 10, a button assembly 13, a temperature acquisition assembly 12, a heating assembly 14, and a heat dissipation assembly 11. The controller 500 is integrated onto the power board 10, which also integrates a power interface 101, a first interface 105, a second interface 103, a third interface 106, a fourth interface 102, and a fifth interface 104. The cleaning base station 100 is connected to an AC power source via the power interface 101. The AC power source for the cleaning base station 100 can be mains power. After power-on, the cleaning base station 100 enters standby mode. The cleaning base station 100 is connected to the cleaning device 200 via the first interface 105, to the temperature acquisition assembly 12 via the second interface 103, to the heating assembly 14 via the third interface 106, to the heat dissipation assembly 11 via the fourth interface 102, and to the button assembly 13 via the fifth interface 104.

[0090] Furthermore, in one embodiment, the button assembly 13 integrates a first indicator light 131, a second indicator light 132, and a button 133. After the user places the cleaning attachment from the cleaning device 200 into the cleaning base station 100 (specifically, the receiving cavity or base in the cleaning base station 100 for receiving the cleaning attachment), and presses the button 133, the controller 500 generates a corresponding self-cleaning command. In response to the self-cleaning command, the controller controls the cleaning base station 100 to output a wake-up pulse sequence through the first interface. This one-button operation greatly simplifies the user's operation steps.

[0091] When the cleaning base station 100 is powered on, the first indicator light 131 remains constantly lit. When the cleaning base station 100 is in drying mode, the second indicator light 132 flashes in a breathing mode. This application provides intuitive feedback on the working status through multimodal status indication, greatly optimizing the user experience.

[0092] The cleaning base station 100 also includes a thermal protector connected between the heating component 14 and the power supply of the heating component 14. The thermal protector is configured to turn off when the sampling temperature collected by the temperature acquisition component 12 is continuously greater than or equal to a first temperature threshold within a set time, and to turn on when the sampling temperature is less than the first temperature threshold.

[0093] The clean base station 100 also includes a thermal fuse connected between the clean base station 100 and its power supply; the thermal fuse is configured to melt when the sampling temperature acquired by the temperature acquisition component 12 is greater than or equal to a second temperature threshold.

[0094] The clean base station 100 also includes a drive circuit, which includes a zero-crossing detection circuit and a bidirectional thyristor switch. The zero-crossing detection circuit is used to detect the zero-crossing point of the AC power supply. The controller is used to generate a PWM signal based on the zero-crossing point of the AC power supply and adjust the duty cycle of the PWM signal according to the difference between the sampled temperature and the target temperature. The bidirectional thyristor switch is connected between the zero-crossing detection circuit and the heating component 14 and the heat dissipation component 11, and is controlled by the PWM signal to control its own on / off state.

[0095] Furthermore, the operating voltage of the cleaning equipment 200 is 35V~36.5V, the operating voltage of the heat dissipation component 11 is 35V, and the common operating voltage of the temperature acquisition component 12, the controller 500 and the button component 13 is 5V. The power board 10 of the cleaning base station 100 generates corresponding 35V~36.5V voltage sources, 5V voltage sources and 35V voltage sources through the internal AC-DC step-down voltage regulator circuit.
