Description

Technical Field

[0001] This application belongs to the field of cleaning technology, and in particular relates to cleaning systems, control methods for cleaning equipment, cleaning equipment, computer-readable storage media, and computer program products. Background Technology

[0002] During self-cleaning, the roller brush of a floor scrubber rotates at high speed, throwing out a large amount of wastewater and dirt. To prevent this dirt from entering the air outlet of the base, a front scraper is often installed in front of the roller brush. The close fit between the front scraper and the base forms a dirt barrier. During the drying stage, the front scraper needs to be raised to create a gap with the base, allowing hot air to pass through smoothly and ensuring that the roller brush is thoroughly dried.

[0003] Currently, self-cleaning solutions for floor scrubbers often switch between a "seal-gap" state for the front squeegee by flipping the scrubber's cover plate up and down: during self-cleaning, the cover plate is pressed down, and the front squeegee seals against dirt; during drying, the cover plate is raised, and the front squeegee clears the air duct. However, in the current solution, the front squeegee directly contacts wastewater and dirt during self-cleaning. After self-cleaning, these stains remain on the front squeegee and cannot be automatically cleaned, requiring manual wiping by the user, which significantly impacts the user experience.

[0004] Therefore, how to automatically clean the dirt from the front squeegee of the floor scrubber in self-cleaning mode, thereby improving the user experience of the floor scrubber, has become a pressing technical problem that needs to be solved. Summary of the Invention

[0005] This application provides a cleaning system, a control method for cleaning equipment, cleaning equipment, a computer-readable storage medium, and a computer program product, which can solve the problem of how to automatically clean the dirt on the front squeegee of a floor scrubber in self-cleaning mode, thereby improving the user's experience of using the floor scrubber.

[0006] In a first aspect, embodiments of this application provide a cleaning system, including:

[0007] A base for holding the brush head assembly of a cleaning device, including a blocking part that mates with the steam nozzle in the brush head assembly; The brush head assembly includes a lifting mechanism, a roller brush, a steam nozzle, a front scraper, a suction channel, and a processor. The suction channel and the lifting mechanism are located on opposite sides of the roller brush, and the steam nozzle is located above the front scraper. The processor controls the lifting mechanism to raise the front scraper to form a steam channel between the front scraper and the base when the brush head assembly is placed on the base and the cleaning device is performing a self-cleaning task; controls the steam nozzle to output steam; and controls the brush head assembly to draw in air through the suction channel. The steam flows forward through the blocking part of the baffle and enters the suction channel through the steam channel.

[0008] In some embodiments, the base also includes a hot air assembly, wherein when the brush head assembly is placed on the base, the air outlet of the hot air assembly is closer to the roller brush than the front scraper. The processor is also used to control the lifting mechanism to lower the front scraper when the brush head assembly is placed on the base and the cleaning equipment is performing a drying task, so that the front scraper and the base are sealed together; to control the hot air assembly to output hot air through the air outlet; and to control the brush head assembly to draw in air through the suction channel, so that the hot air passes through the roller brush and enters the suction channel.

[0009] In some embodiments, the base includes a stepped structure that engages with the front scraper; With the brush head assembly placed on the base and the cleaning device performing a self-cleaning task, the stepped structure and the raised front scraper work together to form a steam channel; With the brush head assembly placed on the base and the cleaning device performing a drying task, the stepped structure and the descending front scraper are sealed together.

[0010] In some embodiments, the air outlet of the hot air assembly of the base is located at the end of the stepped structure of the base and away from the front scraper.

[0011] In some embodiments, the stepped structure is inclined toward the direction of the roller brush.

[0012] In some embodiments, when the brush head assembly is placed on the base, the top of the blocking portion is higher than the location of the steam outlet of the steam nozzle.

[0013] In some embodiments, the steam nozzle includes a plurality of steam outlets, at least one of which is inclined toward the direction of the forward scraper.

[0014] Secondly, this application provides a control method for a cleaning device, which is applied to the cleaning device. The brush head assembly of the cleaning device includes a lifting mechanism, a roller brush, a steam nozzle, a front scraper, and a suction channel. The suction channel and the lifting mechanism are located on opposite sides of the roller brush, the steam nozzle is located above the front scraper, the lifting mechanism is connected to the front scraper, and the base of the cleaning device includes a blocking part that cooperates with the steam nozzle. The methods include: With the brush head assembly placed on the base and the cleaning device performing a self-cleaning task, the lifting mechanism is controlled to raise the front scraper to create a steam channel between the front scraper and the base. Control the steam nozzle to output steam; The control brush head assembly draws in air through the suction channel. The steam flows forward through the obstruction part and scrapes the strip, entering the suction channel through the steam channel.

[0015] In some embodiments, the base also includes a hot air assembly, wherein when the brush head assembly is placed on the base, the air outlet of the hot air assembly is closer to the roller brush than the front scraper. The method also includes: With the brush head assembly placed on the base and the cleaning equipment performing the drying task, control the lifting mechanism to lower the front scraper, so that the front scraper and the base are sealed together. Control the hot air assembly to output hot air through the air outlet; The brush head assembly draws in air through the suction channel, allowing hot air to pass through the roller brush and enter the suction channel.

[0016] Thirdly, embodiments of this application provide a cleaning device including a processor and a memory, the memory storing an application program, and the processor running the application program in the memory to perform the method described in any of the embodiments of the second aspect.

[0017] Fourthly, embodiments of this application provide a computer-readable storage medium storing a computer program that, when executed by a processor, implements the method described in any embodiment of the second aspect.

[0018] Fifthly, embodiments of this application provide a computer program product, including a computer program, which, when run, causes the method described in any embodiment of the second aspect to be executed.

[0019] The advantages of the embodiments in this application compared with related technologies are: When the cleaning equipment is performing a self-cleaning task and is positioned on the base, a steam nozzle located on the same side as the lifting mechanism and above the front scraper blade in the brush head assembly ensures that the high-temperature steam output from this nozzle preferentially flows over the surface of the front scraper blade. Simultaneously, the forced interception by the blocking part in the base ensures that most of the high-temperature steam output from the steam nozzle in self-cleaning mode is directed to the surface of the front scraper blade. In this way, by using the lifting mechanism to raise the front scraper blade, a gap is created between the front scraper blade and the base surface, forming a steam channel for the high-temperature steam to circulate. Simultaneously, controlling the suction channel allows the high-temperature steam intercepted by the blocking part to be drawn into the suction channel after passing through the roller brush. This ensures a continuous flow of high-temperature steam over the surface of the front scraper blade, achieving automated high-temperature steam rinsing and recovery of residual dirt without the need for manual cleaning by the user. Based on this, there is no need to add an independent drive or complex sealing structure. The high-temperature sterilization cleaning of the front scraper and the roller brush can be completed simultaneously in the same task by simply using the inherent positional relationship when the cleaning equipment is parked on the base and the conventional control logic of lifting, steam output and air suction in the self-cleaning mode. This not only improves the hygiene maintenance capability of the cleaning system, but also avoids interrupting the process or increasing user intervention for cleaning the front scraper, thus improving the intelligence of the self-cleaning of the cleaning equipment.

Detailed Implementation

[0029] In the following description, specific details such as preset system structures and techniques are set forth for illustrative purposes and not for limitation, in order to provide a thorough understanding of the embodiments of this application. However, those skilled in the art will understand that this application can also be implemented in other embodiments without these specific details. In other instances, detailed descriptions of well-known systems, apparatuses, circuits, and methods are omitted so as not to obscure the description of this application with unnecessary detail.

[0030] It should also be understood that the term “and / or” as used in this application specification and the appended claims means any combination of one or more of the associated listed items and all possible combinations, and includes such combinations.

[0031] Furthermore, in the description of this application and the appended claims, the terms "first," "second," "third," etc., are used only to distinguish descriptions and should not be construed as indicating or implying relative importance.

[0032] References to "one embodiment" or "some embodiments" in this specification mean that one or more embodiments of this application include the preset features, structures, or characteristics described in connection with that embodiment. Therefore, the phrases "in one embodiment," "in some embodiments," "in other embodiments," "in still other embodiments," etc., appearing in different parts of this specification do not necessarily refer to the same embodiment, but rather mean "one or more, but not all, embodiments," unless otherwise specifically emphasized. The terms "comprising," "including," "having," and variations thereof mean "including but not limited to," unless otherwise specifically emphasized.

[0033] In related technologies, when a floor scrubber is self-cleaning its roller brush, the cover plate is often lowered to create a dirt barrier by tightly fitting the front squeegee on the cover plate against the base of the scrubber. When drying the roller brush, the cover plate is raised to create a gap between the front squeegee and the base, allowing hot air to pass through and dry the brush. However, this approach leaves the front squeegee in direct contact with wastewater and dirt. Neither the cleaning nor drying processes automatically clean the front squeegee; for example, steam won't clean it, leaving residue after self-cleaning that requires manual wiping, significantly impacting the user experience.

[0034] To address the aforementioned issues, this application proposes a cleaning system, a control method for cleaning equipment, cleaning equipment, a computer-readable storage medium, and a computer program product. Through the coordinated operation of a blocking part on the base of the cleaning equipment and the steam nozzle, lifting mechanism, front scraper, and suction channel in the brush head assembly, in self-cleaning mode, the lifting mechanism raises the front scraper to form a steam channel. Simultaneously, the blocking part forcibly intercepts and guides the high-temperature steam output from the steam nozzle to flow directionally across the surface of the front scraper, and then it is drawn into the suction channel through the roller brush side. This achieves automated high-temperature steam rinsing and recovery of residual dirt on the front scraper, improving the user experience of cleaning equipment, such as floor scrubbers.

[0035] The embodiments of this application are described in detail below with reference to specific examples.

[0036] Figure 1 This is a cross-sectional view of a cleaning system according to an embodiment of this application, as shown below. Figure 1 As shown, the cleaning system 1000 includes a cleaning device 100 and a base 200. The cleaning device 100 includes a brush head assembly 110, which includes a lifting mechanism 111, a roller brush 112, a steam nozzle 113, a front scraper 114, an air intake channel 115, and a processor. The air intake channel 115 and the lifting mechanism 111 are located on opposite sides of the roller brush 112, and the steam nozzle 113 is located above the front scraper 114.

[0037] The base 200 is used to hold the brush head assembly 110, including a blocking portion 210 that engages with the steam nozzle 113.

[0038] The processor controls the lifting mechanism 111 to raise the front scraper 114 to form a steam channel between the front scraper 114 and the base 200 when the brush head assembly 110 is placed on the base 200 and the cleaning device 100 is performing a self-cleaning task; controls the steam nozzle 113 to output steam; and controls the brush head assembly 110 to draw in air through the suction channel 115. The steam flows forward through the blocking part 210 and enters the suction channel 115 through the steam channel.

[0039] The cleaning equipment 100 can be a floor scrubber or a vacuum cleaner and mop combo, etc. This application embodiment does not limit the specific type of the cleaning equipment 100, but for convenience, a floor scrubber is used as an example.

[0040] Continue to refer to Figure 1 The lifting mechanism 111 is located at the free end of the brush head cover 116 of the brush head assembly 110, and the free end is the end of the brush head cover 116 away from the body of the cleaning device 100.

[0041] The steam nozzle 113 is also fixed to the free end of the brush head cover plate 116, and the steam nozzle 113 is farther away from the roller brush 112 than the lifting mechanism 111. The steam nozzle 113 can be connected to the instantaneous steam generator inside the cleaning equipment 100 through a high-temperature resistant hose to output steam.

[0042] The front scraper 114 is a long, elastic sealing element, typically made of wear-resistant, oil-resistant, high-temperature-resistant, and aging-resistant rubber or silicone material. Its cross-section can be V-shaped, D-shaped, lip-shaped, or rectangular; no specific limitation is made in this embodiment. It should be noted that when the cleaning device 100 is in charging mode, or has completed the drying process, or is placed on the base 200 but the base 200 is not powered on, or is placed on the ground and not performing a cleaning task—in cases where the front scraper 114 is not required to participate—the front scraper 114 is lifted by the lifting mechanism 111. It is understood that the base 200 needs to be powered on in self-cleaning mode.

[0043] The suction channel 115 is a cavity inside the brush head assembly 110 used to generate negative pressure and draw in air and wastewater. One end of its opening (suction port) is located near the roller brush 112, and the other end is connected to the fan inside the cleaning device 100 via a pipe. When the fan is working, a strong negative pressure is formed in the suction channel 115, which can draw in wastewater from the surface of the roller brush 112, exhaust gas generated during the cleaning process, and steam in this embodiment, and deliver them to the wastewater tank of the cleaning device 100. In this embodiment, the suction channel 115 and the lifting mechanism 111 are located on opposite sides of the roller brush, that is, the suction channel 115 is located on the rear side of the roller brush 112 (the side away from the front scraper 114), while the lifting mechanism 111 is located on the front side of the roller brush 112 (the side closer to the front scraper 114). This opposing arrangement allows the steam to fully pass over the surface of the roller brush 112 when it is drawn into the suction channel 115, thereby achieving efficient cleaning of the roller brush while cleaning the front scraper.

[0044] The blocking part 210 can be a protruding solid or hollow structure located at the end of the brush head assembly 110. Its core function is to forcibly intercept and guide the steam output from the steam nozzle 113. The blocking part 210 can be made of high-temperature resistant, corrosion-resistant, and easy-to-clean materials, such as stainless steel, ceramic, or high-temperature engineering plastics reinforced with glass fiber. No specific limitations are made in this embodiment. For convenience, high-temperature engineering plastics are used as an example.

[0045] The blocking portion 210 extends axially along the roller brush 112 and forms an angle with the steam output direction of the steam outlet in the steam nozzle 113. In this way, most of the steam output from the steam nozzle 113 is deflected by the blocking portion 210 and then passes through the front scraper 114. It is understood that this angle can be acute, right, or obtuse, and can be specifically set according to the path of the steam from the steam output direction to the front scraper 114. In this embodiment, no specific limitation is made on this angle. Optionally, the blocking portion 210 can be perpendicular to the steam output direction.

[0046] The self-cleaning task can be triggered in several ways, such as by a user pressing the self-cleaning button on the cleaning device 100, by remotely issuing a self-cleaning command through a user terminal (e.g., a mobile phone or tablet), or by the processor automatically triggering it after detecting that the dirt level of the roller brush 112 exceeds a threshold. When the self-cleaning task is triggered, the processor determines that the cleaning device 100 is performing the self-cleaning task. The brush head assembly 110 contains a microswitch or interface whose state changes after contacting the base 200. When the processor determines that the cleaning device 100 is performing the self-cleaning task, it can detect the state of the microswitch or interface. If the state is "connected to the base," the processor can determine that the brush head assembly 110 is placed on the base 200 and that the cleaning device 100 is performing the self-cleaning task. At this time, the processor sends a lifting command to the lifting mechanism 111. The lifting mechanism 111 is used to receive the lifting command sent by the processor, lift the front scraper 114, and, upon determining that the front scraper 114 has been lifted, send a first indication signal to the processor to indicate that the front scraper 114 has been lifted. Upon receiving the first indication signal, the processor controls the instantaneous steam generator to produce steam, which is output from the steam nozzle 113. It also controls the fan to operate, generating negative pressure to draw air into the suction channel 115.

[0047] In one implementation, the lifting mechanism 111 may include a lifting frame and a drive unit. The front scraper 114 is fixedly mounted on the lifting frame. The drive unit may be a micro stepper motor, a DC brushed motor with a lead screw and nut mechanism, a worm gear mechanism, or a rack and pinion mechanism, or it may be an electromagnet, a shape memory alloy actuator, or a piezoelectric ceramic actuator, etc. The specific type of drive element is not limited in this application embodiment. For example, the drive unit may be a DC motor with a gearbox, which converts the rotational motion of the DC motor into the linear motion of the lifting frame through a lead screw, thereby realizing the lifting or lowering of the front scraper 114.

[0048] In one implementation, the lifting mechanism 111 further includes a position sensor for detecting whether the lifting frame has reached a preset upper or lower limit position. When the lifting frame reaches the preset upper limit position, the lifting mechanism 111 determines that the front scraper bar has been raised; or, when the lifting frame reaches the preset lower limit position, the lifting mechanism 111 determines that the front scraper bar has been lowered. The position sensor can be a Hall switch, photoelectric switch, micro switch, or potentiometer, etc., and this application embodiment does not impose specific limitations.

[0049] In one implementation, the lifting mechanism 111 further includes a guide unit for smoothly lifting the frame and ensuring its vertical movement without deviation. The guide unit can be a linear guide rail, guide post, guide sleeve, or optical axis, etc., and this application embodiment does not impose specific limitations.

[0050] Considering that the material of the front scraper 114 is often a flexible material, this material will undergo a certain deformation when the cleaning device 100 draws air through the suction channel. Furthermore, the degree of deformation varies depending on the material of the front scraper 114, affecting the size of the gap between the front scraper 114 and the base 200. For example, a larger deformation of the front scraper 114 may widen the steam channel, resulting in greater steam loss. Therefore, in one implementation, the processor can also control the lifting mechanism 111 to raise or lower the front scraper 114 by a certain distance, flexibly changing the gap between the front scraper 114 and the base 200 to accommodate front scrapers 114 made of different materials, or to compensate for manufacturing tolerances and long-term wear and tear on components in the cleaning device, thereby improving the reliability of the front scraper cleaning in self-cleaning mode.

[0051] For example, the lifting command includes a lifting distance; the lifting mechanism 111 includes a distance sensor for detecting the real-time distance between the front scraper 114 and the base 200 and sending it to the drive unit; the drive unit is used to determine that the front scraper 114 has been lifted when the real-time distance is greater than or equal to the lifting distance. The distance sensor can be a miniature laser rangefinder, a miniature ultrasonic rangefinder, or a miniature displacement sensor, etc., and this application embodiment is not limited thereto.

[0052] In one implementation, the steam nozzle 113 is elongated and extends along the axial direction of the roller brush 112. The difference between the length of the steam nozzle 113 and the length of the front scraper 114 is less than or equal to a preset value, such as 0 cm or 1 cm, to ensure that the length of the steam nozzle 113 is approximately equal to the length of the front scraper 114, so that the entire length of the front scraper 114 can be covered by steam.

[0053] In one implementation, the steam nozzle 113 has multiple steam outlets, with at least one steam outlet angled towards the front scraper. This angled design allows the steam output from the steam nozzle to directly wash the surface of the front scraper at a certain incident angle, thereby efficiently removing residual dirt from the surface of the front scraper. Optionally, all the steam outlets may be angled downwards towards the front scraper.

[0054] In one implementation, such as Figure 2 As shown, multiple steam outlets are evenly distributed on the brush head cover. This allows for uniform cleaning of the front scraper 114 surface using steam in self-cleaning mode.

[0055] In one implementation, continue to refer to Figure 1 To allow steam to flow forward towards the front scraper 114 through the obstruction of the obstruction section 210, when the brush head assembly 110 is placed on the base 200, the top of the obstruction section 210 is higher than the steam outlet of the steam nozzle 113. This creates a height difference between the obstruction section 210 and the steam outlet of the steam nozzle 113. This height difference prevents the steam ejected from the steam nozzle 113 from directly crossing the obstruction section 210 and spreading away from the front scraper 114. Instead, the steam impacts the inner wall of the obstruction section 210, causing a change in kinetic energy direction and forcing it to deflect towards the front scraper 114.

[0056] The various components of the aforementioned cleaning system work together. In self-cleaning mode, the lifting mechanism raises the front scraper to create a steam channel. Simultaneously, the blocking part forcibly intercepts and guides the steam output from the steam nozzle to flow directionally across the surface of the front scraper, and then the steam is drawn in through the suction channel by the roller brush. This achieves automated high-temperature steam rinsing and recovery of residual dirt on the front scraper, eliminating the tedious manual cleaning operation for the user. Furthermore, there is no need to add an independent drive or complex sealing structure. The inherent positional relationship when the cleaning equipment is parked on the base and the conventional control logic of the self-cleaning mode can simultaneously complete the high-temperature sterilization cleaning of the front scraper and the roller brush in the same task. This not only improves the hygiene maintenance capability of the cleaning system, but also avoids interrupting the process or requiring user intervention to clean the front scraper, thus enhancing the intelligence of the self-cleaning of the cleaning equipment.

[0057] Generally, after cleaning the roller brush 112 and front scraper 114 in self-cleaning mode, the cleaning device 100 needs to dry the roller brush 112 for the next use. Therefore, after the cleaning device 100 performs the self-cleaning task, it usually performs a drying task, and the hot air required to dry the roller brush 112 is provided by the base 200. If the front scraper 114 is still raised at this time, the hot air will dissipate into the external environment through the steam channel formed during the self-cleaning task, which will not only prolong the drying time of the roller brush but also cause local overheating of the cleaning device 100 or the base 200, thereby affecting the lifespan of the cleaning system. Therefore, in another embodiment, such as Figure 3 As shown, the base 200 also includes a hot air assembly 220. When the brush head assembly 110 is placed on the base 200, the air outlet 221 of the hot air assembly 220 is closer to the roller brush 112 than the front scraper 114.

[0058] The processor is also used to control the lifting mechanism 111 to lower the front scraper 114 so that the front scraper 114 and the base 200 are sealed together when the brush head assembly 110 is placed on the base 200 and the cleaning device 100 is performing a drying task; to control the hot air assembly 220 to output hot air through the air outlet 221; and to control the brush head assembly 110 to draw in air through the suction channel 115 so that the hot air passes through the roller brush 112 and enters the suction channel.

[0059] The hot air assembly 220 includes a heating element 222 and a fan 223. The heating element 222 is used to heat the air, and the fan 223 is used to drive the heated air to flow and form hot air, which is output from the air outlet 221.

[0060] The drying task is usually triggered automatically when the self-cleaning task ends, but it can also be started independently by the user via a button or user terminal, which sends a drying command to the processor. Upon receiving the drying command, the processor sends a descent command to the lifting mechanism 111. The lifting mechanism 111 receives the descent command from the processor, lowers the front scraper 114, and, upon confirming that the front scraper 114 has finished lowering, sends a second indication signal to the processor to indicate that the front scraper 114 has lowered. Upon receiving this second indication signal, the processor sends a start command to the hot air assembly 220. Upon receiving the start command, the hot air assembly 220 heats the air via the heating element 222, uses the fan 223 to drive the heated airflow to form hot air, which is output from the air outlet 221. It also controls the fan to generate negative pressure, causing the suction channel 115 to draw in air. This concentrates the hot air on the side of the front scraper 114 closest to the roller brush 112, and draws it into the suction channel 115 after passing through the roller brush 112.

[0061] Similar to the type of lifting front scraper 114, the descent command may include a descent distance; the drive unit of the lifting mechanism 111 is used to determine that the front scraper 114 has finished descent when the real-time distance is less than or equal to the descent distance.

[0062] In one implementation, such as Figures 1 to 4 As shown, the base 200 includes a stepped structure 230 that mates with the front scraper 114; when the brush head assembly 110 is placed on the base 200 and the cleaning device 100 performs a self-cleaning task, the stepped structure 230 mates with the raised front scraper 114 to form a steam channel; when the brush head assembly is placed on the base and the cleaning device performs a drying task, the stepped structure and the lowered front scraper are sealed together.

[0063] The stepped structure 230 is a planar structure with a certain height difference, located on the surface of the base 200 that supports the brush head assembly 110, near the front scraper 114. The upper surface of the stepped structure 230 is used to contact or form a gap with the front scraper 114, so that when the brush head assembly 110 is placed on the base 200, the front scraper 114 is exactly above the stepped structure 230.

[0064] Combination Figure 5 The diagram shown is a cross-sectional view of a cleaning system including a stepped structure in an embodiment of this application. With the brush head assembly 110 placed on the base 200 and the cleaning device 100 performing a self-cleaning task, the processor controls the lifting mechanism 111 to raise the front scraper 114. At this time, a continuous gap is formed between the upper surface of the stepped structure 230 and the bottom of the raised front scraper 114; this gap is the steam channel. The upper surface of the stepped structure 230 serves as the lower wall of the steam channel, and its flatness directly affects the uniformity of steam flow. Steam is ejected from the steam nozzle 113, guided by the blocking part 210, flows over the surface of the front scraper 114, then enters the channel through the steam channel inlet, flows at high speed along the upper surface of the stepped structure 230, and is finally drawn in by the negative pressure of the suction channel 115 through the surface of the roller brush 112.

[0065] Combination Figure 6 This application embodiment shows a cross-sectional view of a cleaning system including a stepped structure. With the brush head assembly 110 placed on the base 200 and the cleaning device 100 performing a drying task, the processor controls the lifting mechanism 111 to lower the front scraper 114. At this time, the upper surface of the stepped structure 230 tightly adheres to the bottom of the lowered front scraper 114, forming a seal. This seal blocks the airflow channel between the front scraper 114 and the upper surface of the stepped structure 230, preventing hot air leakage and forcing all the hot air to flow towards the roller brush 112. Finally, under the negative pressure of the suction channel 115, the hot air is drawn into the surface of the roller brush 112.

[0066] In this implementation, during self-cleaning, the stepped structure, in conjunction with the raised front scraper, forms a steam channel for cleaning the front scraper; during drying, the stepped structure, in conjunction with the lowered front scraper seal, dries the roller brush. This eliminates the need for separate components for the two cleaning tasks, simplifying the base structure and reducing the cost of the cleaning system. Furthermore, a simple lifting mechanism allows for quick and reliable switching between the steam channel and the sealing state, ensuring the efficiency and reliability of the cleaning equipment's self-cleaning process.

[0067] In one implementation, continue to combine Figure 4 The air outlet 221 of the hot air assembly 220 of the base 200 is located at the end of the stepped structure 230 of the base 200, away from the front scraper. The end of the stepped structure 230 where the air outlet 221 is located refers to the edge of the stepped structure 230 near the roller brush 112, i.e., the root of the stepped structure. The opening direction of the air outlet 221 faces the surface of the roller brush 112. In this implementation, placing the air outlet at the end of the stepped structure and away from the front scraper prevents hot air from blowing directly onto the front scraper, thereby reducing the risk of heat deformation, aging, or sealing failure of the front scraper. Simultaneously, the stepped structure itself can be used as part of the hot air guiding structure, eliminating the need for additional complex air duct design, resulting in a simple structure that is easy to mold and reduces the cost of the cleaning system.

[0068] In one implementation, continue to combine Figures 4 to 6 The stepped structure 230 is inclined towards the roller brush. Specifically, there is a gentle slope between the position where the base 200 supports the roller brush 112 and the end where the air outlet of the stepped structure 230 is located, sloping towards the roller brush 112. During the self-cleaning process, high-temperature steam condenses on the stepped structure, forming water droplets. If the stepped structure is not inclined, this condensate will accumulate in the base, potentially breeding bacteria and being carried out by the airflow during the next cleaning, causing secondary pollution. The inclination of the stepped structure allows water and wastewater to automatically flow downhill under gravity, i.e., towards the roller brush side, and eventually be sucked into the wastewater tank by the suction channel, keeping the base dry and thus maintaining its hygiene.

[0069] In this embodiment, the air outlet is positioned closer to the roller brush than the lifting mechanism, shortening the distance between the hot air and the roller brush, thereby reducing heat loss between the base and the roller brush. Simultaneously, when the brush head assembly is placed on the base and the cleaning device is performing a drying task, the lowering mechanism lowers the front scraper, ensuring a tight seal between the front scraper and the base. This ensures that the hot air from the outlet is confined to the side of the front scraper closest to the roller brush, reducing the possibility of hot air escaping through the gap between the front scraper and the base, and forcing all hot air through the roller brush into the suction channel, thus accelerating drying efficiency. Furthermore, during drying, only the lifting mechanism and suction channel from the self-cleaning task are reused, eliminating the need for additional valves, baffles, or independent seals for the drying task. This simplified control logic achieves simultaneous and rapid drying of the entire process—from the roller brush and suction port to the air duct—improving the user's continuous usage experience while effectively inhibiting bacterial growth and odor generation in humid environments.

[0070] The following method embodiments illustrate the specific process of the steps executed by the processor in the cleaning equipment of the above-mentioned cleaning system. It can be understood that the steps executed by the processor are the same as the steps executed by the cleaning equipment.

[0071] Figure 5 This is a flowchart illustrating a control method for a cleaning device provided in an embodiment of this application. The method is applied to a cleaning device, such as... Figures 1 to 6 In any of the embodiments described, the brush head assembly of the cleaning device includes a lifting mechanism, a roller brush, a steam nozzle, a front scraper, and a suction channel. The suction channel and the lifting mechanism are located on opposite sides of the roller brush, the steam nozzle is located above the front scraper, the lifting mechanism is connected to the front scraper, and the base of the cleaning device includes a blocking part that cooperates with the steam nozzle.

[0072] like Figure 5 The method shown includes: S101, when the brush head assembly is placed on the base and the cleaning device is performing a self-cleaning task, the lifting mechanism is controlled to raise the front scraper to form a steam channel between the front scraper and the base. S102 controls the steam nozzle to output steam; S103, control the brush head assembly to draw in air through the suction channel, the steam is blocked by the obstruction part and scrapes forward, and enters the suction channel through the steam channel.

[0073] In some embodiments, the base also includes a hot air assembly, wherein when the brush head assembly is placed on the base, the air outlet of the hot air assembly is closer to the roller brush than the front scraper. The method also includes: With the brush head assembly placed on the base and the cleaning equipment performing the drying task, control the lifting mechanism to lower the front scraper, so that the front scraper and the base are sealed together. Control the hot air assembly to output hot air through the air outlet; The brush head assembly draws in air through the suction channel, allowing hot air to pass through the roller brush and enter the suction channel.

[0074] For details of each step in the above method, please refer to [link / reference]. Figures 1 to 4 The descriptions of the relevant steps in the illustrated embodiments will not be repeated here.

[0075] In one application scenario, such as Figure 6 As shown, when the floor scrubber (an example of cleaning equipment) is placed on the charging station (an example of a base), the scrubber can determine its real-time status and execute different actions according to instructions, that is, determine the task it is currently performing and control the raising or lowering of the front squeegee accordingly. When the scrubber determines that it is performing a self-cleaning task, it controls its lifting mechanism to raise the front squeegee and executes the self-cleaning procedure (an example of S102 to S103). After self-cleaning is completed, a drying task is triggered, and the lifting mechanism is controlled to lower the front squeegee and execute the drying procedure (an example of controlling the hot air assembly to output hot air through the air outlet and controlling the brush head assembly to draw in air through the suction channel, so that the hot air passes through the roller brush and enters the suction channel). After drying is completed, the lifting mechanism is controlled to raise the front squeegee for user use. When the scrubber determines that it is currently performing a charging task, it also controls the lifting mechanism to raise the front squeegee and enters the charging mode, and then stands by after being fully charged.
