Description

Technical Field

[0001] This application relates to the field of floor cleaning technology, and more particularly to a cleaning device, cleaning equipment, and cleaning system. Background Technology

[0002] A cleaning device is a device used to clean surfaces that need cleaning (such as floors, carpets, tabletops, etc.).

[0003] In related technologies, cleaning devices include a housing assembly, a mopping assembly rotatably mounted on the housing assembly, and a scraper assembly fixedly mounted on the housing assembly. When the cleaning device is in operation, the mopping assembly moves relative to the surface to be cleaned and absorbs dirt (such as wastewater, lint, dust, grime, and paper scraps). The scraper assembly then scrapes off the dirt from the mopping assembly, and a collection device sucks the scraped dirt into a collection box. However, the scraper assembly easily accumulates dirt and grime, which can lead to a series of problems, including affecting the cleaning efficiency of the cleaning device, contaminating the mopping assembly, clogging the filter, and causing odors.

[0043] A cleaning device is a device used to clean surfaces that need cleaning (such as floors, carpets, tabletops, etc.).

[0044] In related technologies, cleaning devices include a housing assembly, a mopping assembly rotatably mounted on the housing assembly, and a scraper assembly fixedly mounted on the housing assembly. When the cleaning device is in operation, the mopping assembly moves relative to the surface to be cleaned and absorbs dirt (such as wastewater, lint, dust, grime, and paper scraps). The scraper assembly then scrapes off the dirt from the mopping assembly, and a collection device sucks the scraped dirt into a collection box. However, the scraper assembly easily accumulates dirt and grime, which can lead to a series of problems, including affecting the cleaning efficiency of the cleaning device, contaminating the mopping assembly, clogging the filter, and causing odors.

[0045] Generally, when cleaning the scraper assembly, the housing assembly needs to be disassembled to remove the scraper assembly or expose it for cleaning. After cleaning, the housing assembly is then reassembled, a time-consuming and labor-intensive process.

[0046] In view of the above problems, this application provides a cleaning device, cleaning equipment and cleaning system, which aims to solve the technical problem of dirt and grime easily accumulating on the scraper assembly.

[0047] To illustrate the technical solution of this application, the dispensing device, cleaning equipment, and cleaning system provided in the embodiments of this application will be described in detail below with reference to the accompanying drawings.

[0048] Figure 1 This is a schematic diagram of a cleaning system according to one embodiment of this application. The cleaning system includes a base station 1000 and a cleaning device 2000. The cleaning device 2000 is used to move on the surface to be cleaned to clean the surface. After cleaning, the cleaning device 2000 can move into the base station 1000. The base station 1000 is used to charge the cleaning device 2000, to collect dirt stored in the cleaning device 2000, to clean the mopping component 2220 in the cleaning device 2000, and to replenish water to the cleaning device 2000, etc.

[0049] Figure 2 and Figure 3 This is a schematic diagram of the structure of a cleaning device 2000 according to one embodiment of this application. The cleaning device 2000 includes a device body 2100 and a cleaning device 2200 disposed on the device body 2100. The device body 2100 is used to drive the cleaning device 2200 to move on the surface to be cleaned, so that the cleaning device 2200 can clean the surface to be cleaned. Optionally, the device body 2100 may also include a clean water tank, a wastewater tank, a wastewater collection device, a moving drive device, and other structures.

[0050] Please refer to Figure 4 , Figure 5 and Figure 6 , Figure 4 This is a schematic diagram of the structure of the cleaning device 2200 provided in some embodiments of this application. Figure 5 This is an exploded structural diagram of the cleaning device 2200 provided in the embodiments of this application. Figure 6 yes Figure 4 A cross-sectional view of the cleaning device 2200 shown.

[0051] The cleaning device 2200 includes a housing assembly 2210, a mopping assembly 2220, a scraper assembly 2230, and a drive assembly 2240. The housing assembly 2210 has a receiving space 2211. The mopping assembly 2220 is rotatably disposed within the receiving space 2211 of the housing assembly 2210, and includes a support portion and a flexible cleaning portion disposed on the outer periphery of the support portion. At least a portion of the scraper assembly 2230 contacts the flexible cleaning portion. The drive assembly 2240 is disposed on the housing assembly 2210, and its drive end is connected to the mopping assembly 2220 to drive the mopping assembly 2220 to rotate selectively in a first direction or in a second direction, the first direction being opposite to the second direction. The cleaning device 2200 has a scraping mode and a scraper cleaning mode. In the scraping mode, the drive assembly 2240 drives the mopping assembly 2220 to rotate in a first direction so as to scrape off dirt from the flexible cleaning part by the scraper assembly 2230. In the scraper cleaning mode, the drive assembly 2240 drives the mopping assembly 2220 to rotate in a second direction so as to clean the scraper assembly 2230 by the flexible cleaning part.

[0052] The housing assembly 2210 is constructed with a receiving space 2211. That is, the housing assembly 2210 includes a U-shaped outer shell 2212, a first side plate 2213 and a second side plate 2214. The U-shaped outer shell 2212 surrounds and forms a through groove. The first side plate 2213 is connected to one end of the U-shaped outer shell 2212 and covers one opening of the through groove. The second side plate 2214 is connected to one end of the U-shaped outer shell 2212 away from the first side plate 2213 and covers the other opening of the through groove, so that the U-shaped outer shell 2212, the first side plate 2213 and the second side plate 2214 surround and form a receiving groove (receiving space 2211).

[0053] Understandably, housing assembly 2210 can be a separate housing or the base plate of cleaning device 2000.

[0054] Drive component 2240 is disposed on housing component 2210, i.e., for example Figure 5The drive assembly 2240 is locked and fixed to the first side plate 2213 by fasteners (screws, rivets, etc.), or the drive assembly 2240 can be snapped and fixed to the first side plate 2213 by a snap-fit ​​connection.

[0055] The drive end of the drive component 2240 is connected to the mopping component 2220. That is, the mopping component 2220 has a receiving cavity, and part of the drive component 2240 is housed in the receiving cavity. The drive end of the drive component 2240 is engaged with the mopping component 2220 so that the drive end of the drive component 2240 can drive the mopping component 2220 to rotate around its own axis.

[0056] The mopping assembly 2220 is rotatably connected to the second side plate 2214 at the end opposite to the drive assembly 2240, so that the mopping assembly 2220 is rotatably disposed within the receiving space 2211 of the housing assembly 2210.

[0057] At least a portion of the outer surface of the mopping assembly 2220 protrudes from the receiving groove through the groove opening, allowing the outer surface of the mopping assembly 2220 to contact the surface to be cleaned. When the cleaning device 2000 moves across the surface to be cleaned to perform cleaning work, the groove opening faces downwards, and the outer surface of the mopping assembly 2220 contacts the surface to be cleaned through the groove opening to clean the surface.

[0058] When the drive component 2240 drives the mopping component 2220 to rotate, at least a portion of the mopping component 2220 can rotate around its own axis in a first direction or a second direction under the drive of the drive component 2240, so that the flexible cleaning part can rotate relative to the surface to be cleaned, thereby increasing the contact area between the mopping component 2220 and the surface to be cleaned, and improving the cleaning efficiency of the cleaning device 2200.

[0059] Please refer to Figure 6 It is understood that the outer periphery of the support portion is provided with a flexible cleaning part, that is, the mopping assembly 2220 includes a rigid member and a flexible member, the flexible member being sleeved around the periphery of the rigid member, and the rigid member being used to support the flexible member. The flexible member can refer to a cylindrical cloth roller brush or a fluffy roller brush. The flexible member includes a main body portion and a flexible cleaning part disposed on the main body portion. In the embodiment of this application, the outer periphery of the support portion is the surface of the fixed end of the main body portion that connects to the flexible cleaning part.

[0060] It is understood that the flexible cleaning part includes at least one of polyamide fiber, polyester fiber, and polypropylene fiber.

[0061] It is understood that at least part of the scraper assembly 2230 is in contact with the flexible cleaning part, that is, the distance between the free end of the flexible cleaning part and the outer periphery of the support part is equal to or greater than the distance between the scraper assembly 2230 and the outer periphery of the support part.

[0062] It is understandable that the distance between the free end of the flexible cleaning part and the outer periphery of the support part refers to the radial distance between the free end of the flexible cleaning part and the fixed end of the flexible cleaning part in the mopping assembly 2220 under the natural state (when the flexible cleaning part is not squeezed).

[0063] Since at least part of the scraper assembly 2230 is in contact with the flexible cleaning section, when the drive assembly 2240 drives the mopping assembly 2220 to rotate in the first direction in the scraping mode, the scraper assembly 2230 scrapes off dirt (such as sewage, lint, dust, mud and paper scraps) in the flexible cleaning section to clean the mopping assembly 2220, so that the mopping assembly 2220 can be reused to improve the cleaning efficiency of the cleaning device 2200.

[0064] Understandably, in its natural state, the free and fixed ends of the flexible cleaning part are roughly distributed radially along the mopping assembly 2220. After the mopping assembly 2220 rotates in the first direction for a certain period of time, the flexible cleaning part is squeezed and flattened by the scraper assembly 2230. That is, the distribution direction of the free and fixed ends of the flexible cleaning part tends to be axially aligned with the mopping assembly 2220, thus reducing the radial distance between the free end of the flexible cleaning part and the outer periphery of the supporting part. This makes it less likely for the free end of the flexible cleaning part to come into contact with the surface of the scraper assembly 2230.

[0065] In the scraper cleaning mode, the drive assembly 2240 drives the mopping assembly 2220 to rotate in the second direction. The scraper assembly 2230 can act as a "comb" to scoop up the flexible cleaning part, so that the distribution direction of the free end and fixed end of the flexible cleaning part tends to be radial to the scraper assembly 2230 of the mopping assembly 2220. This increases the radial distance between the free end of the flexible cleaning part and the outer periphery of the support part, allowing the scooped-up flexible cleaning part to re-contact the scraper assembly 2230. The flexible cleaning part will form an effective wiping and sweeping action on the surface of the scraper assembly 2230, which can re-hook up and remove dirt (such as sewage, lint, dust, mud and paper scraps, etc.) that adhered to the scraper assembly 2230 during the process of the mopping assembly 2220 rotating in the first direction (scraping mode), so as to clean the scraper assembly 2230.

[0066] It is understandable that the mopping assembly 2220 can rotate in the second direction when the cleaning device 2000 is working with the base station 1000 to perform self-cleaning. The dirt that the flexible cleaning part re-hooks up and carries away will be moved to the cleaning tray of the base station 1000. The water output from the base station 1000 can collect the dirt in the cleaning tray into the wastewater tank inside the base station 1000.

[0067] Therefore, in the cleaning device 2200 provided in the first aspect embodiment of this application, when the mopping assembly 2220 rotates in a first direction, the scraper assembly 2230 can scrape off the dirt attached to the mopping assembly 2220 to clean the mopping assembly 2220. When the mopping assembly 2220 rotates in a second direction, the flexible cleaning part contacts the scraper assembly 2230, and the flexible cleaning part forms an effective wiping and sweeping action on the surface of the scraper assembly 2230, which can re-hook up and remove the dirt (such as sewage, lint, dust, mud, and paper scraps) attached to the scraper assembly 2230 during the rotation of the mopping assembly 2220 in the first direction, thereby cleaning the scraper assembly 2230. This design can solve the problem of dirt accumulation on the scraper assembly 2230 due to long-term use.

[0068] Please refer to Figure 6 In some embodiments, the housing assembly 2210 has a dirt collection tank 2215; the scraper assembly 2230 includes a filter element 2231 and a scraper element 2232. The filter element 2231 covers the opening of the dirt collection tank 2215, and the scraper element 2232 is connected to the side wall of the dirt collection tank 2215. When the mopping assembly 2220 rotates in a first direction, the scraper element 2232 is located downstream of the opening of the dirt collection tank 2215. In scraping mode, the scraper element 2232 can scrape away dirt from the flexible cleaning section; in scraper cleaning mode, the flexible cleaning section can clean the scraper element 2232 and the filter element 2231.

[0069] In the above embodiment, since the scraper 2232 is located downstream of the opening of the sludge collection tank 2215 when the mopping assembly 2220 rotates in the first direction, the dirt scraped off by the scraper 2232 will first remain on the surface of the scraper 2232, and then slide into the sludge collection tank 2215, or be sucked into the sludge collection tank 2215 or directly sucked into the collection box under the suction of the sludge collection device.

[0070] In the above embodiment, after the dirt is scraped off by the scraper 2232, it is intercepted by the filter 2231, which can prevent large particles and hair from directly entering the downstream air duct or pump body, thus reducing the risk of blockage. Furthermore, the filter 2231 forms a physical barrier at the trough opening, preventing the dirt already collected in the collection trough 2215 from flowing back with the airflow and causing the dirt to detach from the collection trough 2215, thereby reducing secondary dust and odor diffusion. Additionally, the edge of the filter 2231 can act as a baffle, limiting the swing amplitude of the flexible cleaning part when rotating in the second direction, reducing excessive impact between the flexible cleaning part and the scraper 2232, and lowering the risk of the flexible cleaning part detaching and the scraper 2232 wearing down.

[0071] In the above embodiment, in the scraper cleaning mode, the mopping assembly 2220 rotates in the second direction, and the flexible cleaning part can at least contact the scraper 2232, so that the flexible cleaning part can remove the dirt on the scraper 2232, or the flexible cleaning part can remove the dirt trapped by the filter 2231, so as to clean the scraper 2232 and the filter 2231.

[0072] Please refer to Figure 8 It is understandable that the filter element 2231 has multiple openings, which are evenly distributed on the filter element 2231. This can ensure the function of intercepting dirt while maintaining a stable pressure difference inside and outside the dirt collection tank 2215 and avoiding suction attenuation.

[0073] In some embodiments, the scraper assembly 2230 is detachably connected to the housing assembly 2210, and the filter element 2231 can be removed from the housing assembly 2210 when it is necessary to clean the filter element 2231.

[0074] Please refer to Figure 6 In other embodiments, the scraper assembly 2230 and the housing assembly 2210 are integrally formed.

[0075] Understandably, the scraper 2232 can be a scraper or scraper made of rubber, silicone or other elastic materials, or it can be a scraper or scraper integrally formed with the side wall of the sludge collection tank 2215. The material of the scraper 2232 depends on the material selection of the housing assembly 2210 as a whole.

[0076] Please refer to Figure 6 and Figure 7 In some embodiments, the scraping member 2232 has a scraping edge 2232-1, and the distance between the free end of the flexible cleaning part and the outer periphery of the support part is greater than the distance between the scraping edge 2232-1 and the outer periphery of the support part.

[0077] Understandably, the scraping edge 2232-1 refers to the edge on the scraping part 2232. The scraping edge 2232-1 is used to directly contact the mopping assembly 2220 and to scrape off dirt from the flexible cleaning part.

[0078] In some embodiments, the distance between the free end of the flexible cleaning part and the outer periphery of the support part is equal to or greater than the distance between the filter element 2231 and the outer periphery of the support part.

[0079] In the above embodiment, when the mopping assembly 2220 rotates in the second direction, the scraper 2232 acts as a "comb" to lift the flexible cleaning part. Since the distance between the free end of the flexible cleaning part and the outer periphery of the support part is equal to or greater than the distance between the filter element 2231 and the outer periphery of the support part, the flexible cleaning part can contact the filter element 2231. The flexible cleaning part will effectively wipe and sweep the surface of the filter element 2231, and can re-hook up and remove the dirt (such as sewage, lint, dust, mud, and paper scraps) that adhered to the filter element 2231 during the rotation of the mopping assembly 2220 in the first direction, thereby cleaning the filter element 2231. The filter element 2231 can be cleaned without removing it from the housing assembly 2210 or with the scraper assembly 2230 and the housing assembly 2210 being integrally formed.

[0080] Please refer to Figure 7 In some embodiments, the scraper 2232 also has a first surface 2232-2 extending from the scraping edge 2232-1 toward the sludge collection groove 2215, wherein when the mopping assembly 2220 rotates in a first direction, the end of the first surface 2232-2 near the scraping edge 2232-1 is located downstream of the end of the first surface 2232-2 near the sludge collection groove 2215.

[0081] In the above embodiment, when the mopping assembly 2220 rotates in the first direction, the end of the first surface 2232-2 near the scraping edge 2232-1 is located downstream of the end of the first surface 2232-2 near the dirt collection tank 2215. That is, when the cleaning device 2200 is in use, the opening of the accommodating space 2211 faces downward, and the end of the first surface 2232-2 away from the dirt collection tank 2215 is located below the end of the first surface 2232-2 near the dirt collection tank 2215, so that the first surface 2232-2 is a downwardly inclined slope.

[0082] Understandably, when the mopping assembly 2220 rotates in the first direction, the dirt scraped off the flexible cleaning section by the scraping blade 2232-1 has an initial tangential velocity. The inclined design of the first surface 2232-2 provides a natural, smooth, and least-resistance guiding channel for the dirt with initial velocity. After the dirt impacts the first surface 2232-2, its momentum is effectively decomposed into a component that moves towards the dirt collection tank 2215, allowing the dirt to be smoothly guided into the dirt collection tank 2215, reducing the possibility of dirt splashing, bouncing, or getting stuck near the scraping blade 2232-1. Furthermore, by making the scraper 2232 "guide" rather than "shovel" dirt off the mopping assembly 2220, the contact friction between the scraper 2232 and the flexible cleaning part is reduced. This means that the drive assembly 2240 requires less torque to rotate the mopping assembly 2220, thus reducing the overall energy consumption of the cleaning device 2200 and helping to extend battery life or reduce heat dissipation. At the same time, lower contact friction also means lower operating noise and a longer lifespan for the mopping assembly 2220 and the scraper 2232.

[0083] Understandably, the downward-sloping first surface 2232-2 not only optimizes the scraping efficiency of the scraper 2232 when the mopping assembly 2220 rotates in the first direction, but also provides benefits when the mopping assembly 2220 rotates in the second direction. For example, the downward-sloping first surface 2232-2 can minimize the accumulation of dirt at the junction of the first surface 2232-2 and the side wall of the dirt collection groove 2215 (i.e., the root of the scraping blade 2232-1). Furthermore, when the mopping assembly 2220 rotates in the second direction, guided by the first surface 2232-2, the flexible cleaning part can more easily penetrate into the root of the scraping blade 2232-1 to wipe and clean the root of the scraping blade 2232-1, thereby more effectively hooking up and removing dirt entangled at the root of the scraping blade 2232-1, thus improving the thoroughness of cleaning the scraper 2232.

[0084] In some embodiments, a reference plane 2250 is used, which is a plane passing through the scraping blade 2232-1 and parallel to the rotation axis of the mopping assembly 2220. Figure 7 (As shown by the dashed line in the middle), the first surface 2232-2 and the reference plane 2250 form a first working angle α, which is 15° to 70°.

[0085] It should be noted that if the first working angle α is too small, the inclination of the first surface 2232-2 will be too large. This will cause dirt (especially liquid) to splash and bounce more easily when it hits the first surface 2232-2, rather than be guided and collected. It will also make the head of the scraper 2232 too "bulky", increasing unnecessary contact resistance and wear between the scraper 2232 and the mopping assembly 2220. The lower limit of 15° can suppress dirt bounce while ensuring the lightweight nature of the scraper 2232.

[0086] It should be noted that if the first working angle α is too large, the inclination of the first surface 2232-2 will be too "gentle," weakening its guiding effect. Dirt will easily accumulate on the first surface 2232-2, requiring greater centrifugal force to be thrown into the collection tank 2215. Furthermore, when the mopping assembly 2220 rotates in the second direction, it is not conducive to the removal of dirt from the first surface 2232-2. An upper limit of 70° ensures that the first surface 2232-2 has a sufficiently steep slope while also providing a clear and effective guiding force for the dirt, ensuring its smooth sliding into the collection tank 2215.

[0087] In the above embodiment, by limiting the first working angle α to 15° to 70°, the scraping member 2232 generates a better hydrodynamic pressure effect when cutting into the liquid film on the surface of the mopping assembly 2220. This effectively lifts and scrapes away the liquid in the mopping assembly 2220 while avoiding the significant resistance that can occur with a right-angle structure. This keeps the torque required by the drive assembly 2240 to rotate the mopping assembly 2220 at a low level, reducing overall power consumption, improving battery life, and helping to control operating noise. Furthermore, this angle prevents the scraping edge 2232-1 from forming an excessively sharp angle, preventing the flexible cleaning part from being cut or excessively worn by the scraping edge 2232-1 during high-speed rotation, thus extending the service life of the mopping assembly 2220.

[0088] Please refer to Figure 7 In some embodiments, the scraper 2232 further has a second surface 2232-3 extending from the scraping edge 2232-1 in a direction away from the mopping assembly 2220. The second surface 2232-3 is disposed opposite to the first surface 2232-2. When the mopping assembly 2220 rotates in a first direction, the end of the second surface 2232-3 near the scraping edge 2232-1 is located upstream of the end of the second surface 2232-3 away from the mopping assembly 2220.

[0089] In the above embodiment, when the mopping assembly 2220 rotates in the first direction, the end of the second surface 2232-3 near the scraping edge 2232-1 is located upstream of the end of the second surface 2232-3 away from the mopping assembly 2220. That is, when the cleaning device 2200 is in use, the slot of the accommodating space 2211 faces downward, and the end of the second surface 2232-3 near the scraping edge 2232-1 is located above the end of the second surface 2232-3 away from the mopping assembly 2220, so that the second surface 2232-3 is an upwardly inclined slope.

[0090] In the above embodiment, the second surface 2232-3 is tilted upward, forming a sharp and efficient scraping edge at the scraping blade 2232-1. This allows the flexible cleaning part to slide from the second surface 2232-3 past the scraping blade 2232-1 and then contact the first surface 2232-2, enabling the flexible cleaning part to better "pry up" or "scrape" the dirt on the first surface 2232-2, thereby efficiently removing the dirt retained on the scraping member 2232.

[0091] Understandably, when the mopping assembly 2220 rotates in the second direction, an airflow or waterflow is generated around it. The second surface 2232-3, which has an upwardly inclined configuration, can smoothly cleave and guide this fluid, greatly reducing the eddies and air resistance (or fluid resistance) generated at the tail of the scraper 2232. This further reduces the load on the drive assembly 2240 and the overall energy consumption when the mopping assembly 2220 rotates in the second direction. At the same time, due to the smoother fluid separation, the operating noise is also effectively suppressed.

[0092] In some embodiments, a reference plane 2250 is used, which is a plane passing through the scraping blade 2232-1 and parallel to the rotation axis of the mopping assembly 2220. Figure 7 (As shown by the dashed line in the middle), the second surface 2232-3 and the reference plane 2250 form a second working angle β, which is 15° to 20°.

[0093] It should be noted that when the second working angle β is too small, the inclination of the second surface 2232-3 is too large, which will cause the head of the scraper 2232 to be too "bulky". This will not only increase the unnecessary contact resistance and wear between the scraper 2232 and the mopping assembly 2220, but also significantly increase the fluid resistance generated at the tail of the scraper 2232, resulting in a poorer noise reduction effect.

[0094] It should be noted that when the second working angle β is too large, although theoretically the fluid resistance generated at the tail of the scraper 2232 is smaller and the scraping edge 2232-1 of the scraper 2232 is sharper, the scraping edge 2232-1 will be too fragile, and the fatigue resistance and wear resistance will drop sharply, making it unable to withstand long-term operation.

[0095] In the above implementation, limiting the second working angle β to the range of 15° to 20° is a balance point that combines the three major characteristics of "low wind resistance", "scraping sharpness" and "structural reliability".

[0096] Please refer to Figure 2 In some embodiments, the cleaning device 2200 further includes a sweeping assembly 2260, which is located in front of the mopping assembly 2220 in the direction of movement of the cleaning device 2200 (X direction in the figure).

[0097] In the above embodiment, when cleaning the surface to be cleaned, the sweeping component 2260 first sweeps away larger-volume dirt or dirt that is not attached to the surface to be cleaned (such as paper scraps, hair, etc.), and then the mopping component 2220 mops the surface to be cleaned to remove dirt or dust that is difficult to clean, thereby improving the cleaning efficiency of the cleaning device 2200.

[0098] In some embodiments, the scraper assembly 2230 is located on the side of the mopping assembly 2220 opposite to the sweeping assembly 2260.

[0099] In some embodiments, the drive assembly 2240 includes a motor and a direction control unit, the direction control unit being configured to cause the motor to selectively drive the mopping assembly 2220 to rotate in a first direction or a second direction.

[0100] In the above embodiments, the introduction of the direction control unit upgrades the bidirectional rotation function from a manual, passive mechanical operation to an intelligent, programmable active control function. This allows the cleaning device 2200 to automatically and accurately switch between "scraping mode" (mopping component 2220 rotates in the first direction) and "scraper cleaning mode" (mopping component 2220 rotates in the second direction) based on a preset program or real-time sensor feedback, without user intervention. This greatly enhances the product's intelligence level and user experience. The direction control unit controls the motor's direction by sending precise electrical signals, avoiding the risks of jamming, wear, and poor contact inherent in mechanical reversing mechanisms. Each direction switch is fast, accurate, and reliable, ensuring that the self-cleaning function can be executed 100% reliably when needed, thereby maintaining the efficient operation of the scraping component 2232 and the entire cleaning system.

[0101] The directional control unit can integrate and process signals from various sensors, such as a current sensor to detect motor load and determine blockage, a timer for periodic self-cleaning, and an optical sensor to detect the cleanliness of the mopping assembly 2220. For example, when the directional control unit detects a continuous increase in motor current (indicating that the filter 2231 may be blocked, leading to increased resistance), it can automatically trigger reverse rotation for self-cleaning. Another example is that it can automatically reverse rotation for 15 seconds every 5 minutes of operation to prevent blockage.

[0102] In the above implementation, the direction control unit can be a microcontroller-based intelligent control unit, the core of which is an MCU (Micro Controller Unit) running a pre-written control program. The MCU's general-purpose input / output pins emit high / low level control signals. These signals are sent to the corresponding pins of the motor driver chip. Based on the received signal combinations, the motor driver chip controls the direction of the current output to the motor terminals, thereby achieving forward and reverse rotation of the motor. Microcontroller-based intelligent control units have a high degree of intelligence. They can easily integrate functions such as timing, load detection, and sensor feedback to implement complex control strategies.

[0103] In the above embodiments, the direction control unit can be a motor driver integrated circuit, which can control the motor direction through simple pin level configuration or input pulse sequences. Examples include dual H-bridge driver chips such as L293D, DRV8833, and TB6612FNG. These can themselves be considered simple, configurable direction control units. Specific logic level combinations are directly input to the control pins of the driver chip (e.g., IN1=1, IN2=0 represents forward rotation; IN1=0, IN2=1 represents reverse rotation). The circuit is simple, low-cost, and highly reliable.

[0104] In the above implementation, the direction control unit can be a digital control unit based on logic gate circuits. It uses basic digital logic chips (such as AND gates, OR gates, NOT gates, and flip-flops) to build a simple combinational or sequential logic circuit to generate the signals required to control the motor direction. An external trigger signal (such as pressing a button) changes the state of the flip-flop, and its output state determines the signal combination sent to the motor drive circuit, thereby achieving commutation. It is purely hardware-based, has a fast response speed, and requires no programming.

[0105] In the above embodiments, the direction control unit can be a relay-based electromechanical control unit, using one or more relays to change the direction of current flow in the motor coil. The direction control unit outputs a signal to drive the relay coil to engage or disengage, thereby changing the connection method of the relay's internal contacts and physically switching the power polarity at both ends of the motor. Its circuit is simple and easy to understand, and it can control high-power motors.

[0106] To achieve the above objectives, the technical solution adopted in the second aspect of this application is: a cleaning device 2000, including a device body 2100 and a cleaning device 2200 of the first aspect embodiment, wherein the cleaning device 2200 is disposed on the device body 2100.

[0107] By applying the cleaning device 2200 of the first aspect embodiment described above to the cleaning equipment 2000, the problem of dirt and grime accumulating on the scraper 2232 due to long-term use can be solved.

[0108] It is understandable that cleaning equipment 2000 can be, but is not limited to, robotic vacuum cleaners, floor scrubbers, robotic vacuum and mop combos, vacuum cleaners, etc.

[0109] In some embodiments, the cleaning device 2000 also includes a dirt collection device for collecting dirt scraped off by the scraper assembly 2230.

[0110] In the above embodiment, the suction port of the sludge collection device is connected to the sludge collection tank 2215, and the sludge collection device is used to generate suction.

[0111] The dirt scraped off by the scraper 2232 in the collection tank 2215 is actively and quickly sucked into a larger collection container (such as a dust box or sewage tank) through the suction port, so as to prevent dirt from clogging in the collection tank 2215 or from overflowing from the collection tank 2215.

[0112] In some embodiments, the sludge collection device includes a power source (centrifugal fan, crossflow fan, air pump, etc.), a sludge separation unit (filter, cyclone separator, etc.), a storage unit (sludge tank / dust box), and an air duct structure. The power source generates suction, and the sludge separation unit separates the sludge from the airflow after it is drawn from the collection tank 2215 by suction, preventing sludge from entering the fan and causing damage. The storage unit stores the sludge separated from the airflow. The air duct structure forms a sealed path connecting the intake, sludge separation unit, storage unit, and power source. An opening is made in the bottom or side wall of the collection tank 2215. The inlet of the air duct structure (the intake of the sludge collection device) connects to this opening, and the outlet of the air duct structure is connected to and communicates with the storage unit. The sludge separation unit is located inside the storage unit. The power source is connected in series in the path of this air duct structure. Typically, the air inlet of the power source is connected to the collection tank 2215 through the air duct structure, and the air outlet of the power source is connected to the sludge separation unit through the air duct structure.

[0113] In the scraping mode, the cleaning device 2200 moves on the surface to be cleaned, the mopping assembly 2220 absorbs dirt from the surface, and the drive assembly 2240 drives the mopping assembly 2220 to rotate in a first direction, causing the scraper 2232 to scrape off the dirt from the mopping assembly 2220, allowing the dirt to slide into the dirt collection tank 2215. The power source in the dirt collection device operates, causing the dirt in the dirt collection tank 2215 to be sucked into the air duct structure, and the airflow flows sequentially through the dirt separation unit and the storage unit, causing the dirt in the airflow to be separated by the dirt separation unit and stored in the storage unit.

[0114] To achieve the above objectives, the technical solution adopted in the third aspect of this application is: a cleaning system, including a base station 1000 and a cleaning device 2000 as described in the second aspect of the embodiment, wherein the cleaning device 2000 is used in conjunction with the base station 1000.

[0115] By applying the cleaning device 2000 of the second aspect embodiment described above to the cleaning system, the problem of dirt and grime accumulating on the scraper 2232 due to long-term use can be solved.

[0116] The base station 1000 is used to charge the cleaning equipment 2000, recycle dirt in the storage unit of the cleaning equipment 2000, clean the mopping component 2220 in the cleaning equipment 2000, and replenish water to the cleaning equipment 2000.

[0117] The above embodiments are only used to illustrate the technical solutions of this application, and are not intended to limit them. Although this application has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some of the technical features. Such modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the spirit and scope of the technical solutions of the embodiments of this application, and should all be included within the protection scope of this application.
