Description

A floor cleaning brush, cleaning equipment and cleaning system Technical Field

[0001] This application relates to the field of cleaning technology, and in particular to a cleaning brush, cleaning equipment and cleaning system. Background Technology

[0002] Currently, cleaning equipment with dual roller brushes on the market uses a dual air duct system with a larger front and a smaller rear air duct. During use, the suction power of the dual air ducts is dispersed, resulting in insufficient suction power in the front air duct and incomplete cleaning. When the floor brush moves backward, the rear air duct is prone to clogging due to its smaller diameter and weaker suction power, and water backflow is also obvious. This constitutes a fatal flaw of dual roller brush dual air duct cleaning equipment, which greatly affects the user experience.

[0003] For example, Chinese patent CN217592737U discloses a cleaning device with an air duct and a floor scrubber having the same. The cleaning airflow from the front suction port through the front air duct to the converging air duct travels a shorter distance than the cleaning airflow from the rear suction port through the rear air duct to the converging air duct. The front roller brush is the primary cleaning roller brush, and the rear roller brush is the secondary cleaning roller brush. The front air duct absorbs more material than the rear air duct. Summary of the Invention

[0004] The purpose of this application is to provide a cleaning brush, cleaning equipment, and cleaning system.

[0005] The embodiments of this application adopt the following technical solution: a floor cleaning brush, comprising:

[0006] Housing components;

[0007] A first roller brush is disposed at the front end of the housing assembly and is capable of rolling contact with the ground;

[0008] The second roller brush is located at the rear end of the housing assembly and is capable of rolling contact with the ground;

[0009] The first air duct has one end close to the first roller brush and is connected to the outside.

[0010] The second air duct has one end close to the second roller brush and is connected to the outside.

[0011] The third air duct has one end close to the other end of the first air duct and the other end of the second air duct, and the other end of the third air duct is connected to the main component of the cleaning equipment.

[0012] An air duct conversion component is disposed at the intersection of the first, second, and third air ducts. When the cleaning brush moves forward, the air duct conversion component moves around a first direction to block the second air duct and connect the first and third air ducts, thereby allowing dirt on the floor to enter the cleaning brush through the first and third air ducts. When the cleaning brush moves backward, the air duct conversion component moves around a second direction to block the first air duct and connect the second and third air ducts, thereby allowing dirt on the floor to enter the cleaning brush through the second and third air ducts.

[0013] Wherein, the first direction is opposite to the second direction.

[0014] When the local brush moves forward, the air duct switching component moves, connecting the first and third air ducts at the front while simultaneously closing the second air duct at the rear. When the local brush moves backward, it connects the second and third air ducts at the rear while simultaneously closing the first air duct at the front. The movement of the air duct switching component achieves the switching of air ducts, thus ensuring a strong suction force in a single air duct during operation and reducing air duct switching time and the chance of clogging the suction port. This solves the shortcomings of existing dual roller brush technologies, enabling a true dual roller brush cleaning system with dual air ducts that can suction at will, reducing user limitations and greatly improving the user experience.

[0015] In some embodiments, one end of the air duct conversion component is provided with a first rotating shaft, and the other end of the air duct conversion component is provided with a second rotating shaft; the middle part of the air duct conversion component is an arc-shaped plate, and both ends of the arc-shaped plate are sealing plates; when the air duct conversion component blocks the second air duct, the outer plate surface of the arc-shaped plate faces the second air duct; when the air duct conversion component blocks the first air duct, the outer plate surface of the arc-shaped plate faces the first air duct.

[0016] The first or second air duct can be switched by using an arc-shaped plate, and the switching process can be completed smoothly through the arc-shaped plate.

[0017] In some embodiments, a scraper is provided on the outer surface of the arc-shaped plate to reduce friction between the air duct conversion component and the housing assembly forming the first or second air duct when the air duct is blocked.

[0018] In some embodiments, the inner surface of the arc-shaped plate is a smooth arc-shaped surface. When the first air duct and the third air duct are connected, the smooth arc-shaped surface can smoothly connect the first air duct and the third air duct; when the second air duct and the third air duct are connected, the smooth arc-shaped surface can smoothly connect the second air duct and the third air duct.

[0019] The inner surface of the curved plate is a smooth curved surface, which makes it less likely for dirt to accumulate at the connection between the first or second air duct and the third air duct when they are connected.

[0020] In some embodiments, the first or second rotating shaft is connected to a drive member, and a visualization window is also provided on the first or second rotating shaft connected to the drive member for observing the connection between the drive member and the first or second rotating shaft.

[0021] In some embodiments, the housing assembly includes an upper housing assembly, a lower housing assembly, and a floor brush head, wherein the upper housing assembly is disposed on the lower housing assembly, and the lower housing assembly is disposed on the floor brush head;

[0022] The cleaning brush also includes a fixed base, which is detachably mounted on the brush head. The fixed base is hinged to the first and second rotating shafts of the air duct conversion component, so that the air duct conversion component can rotate relative to the fixed base.

[0023] By mounting the air duct conversion component on a fixed base, which is detachably mounted on the housing assembly, the air duct conversion component can be quickly disassembled.

[0024] In some embodiments, both the first rotating shaft and the second rotating shaft are provided with annular protrusions surrounding the axes of the first rotating shaft and the second rotating shaft;

[0025] The fixed base has grooves at both ends that mate with the annular protrusions respectively. The annular protrusions are placed in the grooves and rotate under the guidance of the grooves.

[0026] The combination of the annular protrusion and the groove allows for good positioning and guidance of the air duct switching component, enabling it to rotate stably and switch between the first, second, and third air ducts.

[0027] In some embodiments, a first soft scraper is provided at one end of the first air duct near the first roller brush; a second soft scraper is provided at one end of the second air duct near the second roller brush.

[0028] The first and second soft scraper strips are in contact with the ground.

[0029] The soft squeegee contacts the ground and can scrape away water stains and debris sucked up by the roller brush when cleaning the ground.

[0030] This application embodiment also provides a cleaning device, including a cleaning brush as described in any of the above embodiments, and further including a main body component, the main body component including:

[0031] The body assembly includes a motherboard that controls the movement direction of the air duct conversion component of the cleaning brush;

[0032] A handle assembly, which is disposed on the body assembly;

[0033] A sub-unit, which is disposed on the body assembly, is used to provide power and suction to the cleaning device;

[0034] A dust cup assembly, which is disposed on the body assembly and communicates with the third air duct of the cleaning brush, is used to receive dirt from the third air duct.

[0035] This application embodiment also provides a cleaning device, including a cleaning brush as described in any of the above embodiments, and further including a main body component, the main body component including:

[0036] The body assembly includes a motherboard that controls the movement direction of the air duct conversion component of the cleaning brush;

[0037] A handle assembly, which is disposed on the body assembly;

[0038] A sub-unit, which is disposed on the body assembly, is used to provide power and suction to the cleaning device;

[0039] A wastewater tank assembly, which is mounted on the body assembly and communicates with the third air duct of the cleaning brush, is used to receive dirt from the third air duct.

[0040] A clean water tank assembly, which is mounted on the body assembly, is used to provide cleaning water for the cleaning equipment.

[0041] This application embodiment also provides a cleaning system, including a base station and cleaning equipment, wherein the base station includes a fan and a hot air duct, and the hot air duct has a first hot air outlet and a second hot air outlet;

[0042] When the cleaning equipment is placed on the base station and dried, the air duct conversion component of the cleaning brush moves to a preset position, and the fan and the sub-unit provide suction so that the first air duct and the second air duct of the cleaning brush are connected to the third air duct. This allows the fan to blow hot air out through the first hot air outlet and the second hot air outlet, and blow it through the hot air duct to the first air duct, the second air duct and the third air duct of the cleaning brush.

[0043] The beneficial effects of the embodiments of this application are as follows:

[0044] When the local brush moves forward, the air duct switching component moves, connecting the first and third air ducts at the front while simultaneously closing the second air duct at the rear. When the local brush moves backward, it connects the second and third air ducts at the rear while simultaneously closing the first air duct at the front. The movement of the air duct switching component achieves the switching of air ducts, thus ensuring a strong suction force in a single air duct during operation and reducing air duct switching time and the chance of clogging the suction port. This solves the shortcomings of existing dual roller brush technologies, enabling a true dual roller brush cleaning system with dual air ducts that can suction at will, reducing user limitations and greatly improving the user experience.

[0071] This specification may use the phrases “in one embodiment,” “in another embodiment,” “in yet another embodiment,” or “in other embodiments,” all of which may refer to one or more of the same or different embodiments according to this application.

[0072] For cleaning equipment currently on the market with switching suction ducts, the floor brush section features a drive gear connected to an external gear. Several support gears rotatably connect to the external gear, allowing the switching duct to rotate vertically and switch between the front and rear suction ducts. This complex drive gear module transmission structure significantly increases product cost. Furthermore, during prolonged use, slow duct switching can lead to buildup at the suction port, causing switching failures and varying degrees of blockage. These structural features drastically reduce the lifespan of the drive motor, decrease cleaning performance, and make unclogging difficult, time-consuming, and laborious for users.

[0073] This application provides a cleaning brush 6, as shown in Figures 11, 2, 3 and 4. The cleaning brush 6 includes a housing assembly, a first roller brush 7, a second roller brush 8, a first air duct 6.3.2, a second air duct 6.3.3, a third air duct 6.3.4 and an air duct conversion component 6.4.

[0074] The housing assembly serves as the mounting base for other mounting structural components. It provides mounting space or locations for these other components.

[0075] The first roller brush 7 is located at the front end of the housing assembly and is capable of rolling contact with the ground. The second roller brush 8 is located at the rear end of the housing assembly and is also capable of rolling contact with the ground. The rolling of the first roller brush 7 and the second roller brush 8 can clean the areas on the ground that need to be cleaned.

[0076] One end of the first air duct 6.3.2 is close to the first roller brush 7 and communicates with the outside. One end of the second air duct 6.3.3 is close to the second roller brush 8 and communicates with the outside. There is a certain gap between one end of the first air duct 6.3.2 and the first roller brush 7, and there is also a certain gap between one end of the second air duct 6.3.3 and the second roller brush 8, so that dirt on the ground can enter the first air duct 6.3.2 through the gap between one end of the first air duct 6.3.2 and the first roller brush 7, or so that dirt on the ground can enter the second air duct 6.3.3 through the gap between one end of the second air duct 6.3.3 and the second roller brush 8.

[0077] One end of the third air duct 6.3.4 is close to the other end of the first air duct 6.3.2 and the other end of the second air duct 6.3.3. The other end of the third air duct 6.3.4 is connected to the main body component of the cleaning equipment so that dirt passing through the first air duct 6.3.2 or the second air duct 6.3.3 can enter the third air duct 6.3.4 and then enter the main body component of the cleaning equipment for dirt collection.

[0078] The air duct conversion component 6.4 is located at the intersection of the first air duct 6.3.2, the second air duct 6.3.3, and the third air duct 6.3.4. When the cleaning brush 6 moves forward, the air duct conversion component 6.4 moves in a first direction to block the second air duct 6.3.3 and connect the first air duct 6.3.2 with the third air duct 6.3.4, allowing dirt from the floor to enter the cleaning brush 6 through the first air duct 6.3.2 and the third air duct 6.3.4. When the cleaning brush 6 moves backward, the air duct conversion component 6.4 moves in a second direction to block the first air duct 6.3.2 and connect the second air duct 6.3.3 with the third air duct 6.3.4, allowing dirt from the floor to enter the cleaning brush 6 through the second air duct 6.3.3 and the third air duct 6.3.4. The first direction and the second direction are opposite. The air duct conversion component 6.4 can change position according to the movement direction of the cleaning brush 6, so that the cleaning brush 6 maintains single-air duct operation. This ensures strong suction from a single air duct during operation, improves the utilization rate of the suction motor 2.5, and reduces air duct switching time and the probability of suction port clogging. This solves the shortcomings of existing dual-roller brushes in the cleaning brush 6, enabling easy switching between dual-roller brushes and dual air ducts for cleaning, greatly improving the user experience. Here, "single air duct" refers to the air duct composed of the first air duct 6.3.2 and the third air duct 6.3.4 when the cleaning brush 6 moves forward; or it refers to the air duct composed of the second air duct 6.3.3 and the third air duct 6.3.4 when the cleaning brush 6 moves backward.

[0079] It should be noted that forward movement refers to directions such as directly in front, left front, and right front, while backward movement refers to directions such as directly behind, left rear, and right rear, rather than a single absolute forward or backward direction.

[0080] In this embodiment, when the cleaning brush 6 moves forward, the air duct conversion component 6.4 activates, connecting the first air duct 6.3.2 and the third air duct 6.3.4 at the front, while simultaneously closing the second air duct 6.3.3 at the rear. When the brush moves backward, it connects the second air duct 6.3.3 at the rear and the third air duct at the third, while simultaneously closing the first air duct 6.3.2 at the front. The air duct switching is achieved through the action of the air duct conversion component 6.4, thereby ensuring a strong suction force in a single air duct during operation and reducing air duct switching time and the probability of clogging the suction port. This solves the defects of the existing dual roller brushes, enabling true dual roller brush cleaning with dual air ducts that can be used for cleaning in both the front and rear, reducing user limitations and greatly improving the user experience.

[0081] In some embodiments, as shown in Figures 8, 9, and 10, a first rotating shaft 6.4.2 is provided at one end of the air duct conversion component 6.4, and a second rotating shaft 6.4.3 is provided at the other end. The middle part of the air duct conversion component 6.4 is an arc-shaped plate 6.4.1, with sealing plates at both ends. The sealing plates can seal both ends of the arc-shaped plate 6.4.1. The first rotating shaft 6.4.2 and the second rotating shaft 6.4.3 can be respectively provided on the sealing plates at both ends of the arc-shaped plate 6.4.1. When the air duct conversion component 6.4 blocks the second air duct 6.3.3, the outer plate surface of the arc-shaped plate 6.4.1 faces the second air duct 6.3.3; when the air duct conversion component 6.4 blocks the first air duct 6.3.2, the outer plate surface of the arc-shaped plate 6.4.1 faces the first air duct 6.3.2. The arc-shaped plate 6.4.1 enables the switching between blocking the first air duct 6.3.2 and the second air duct 6.3.3, and the switching process can be smoothly completed through the arc-shaped plate 6.4.1.

[0082] In addition, a scraper 6.4.4 can be provided on the outer plate surface of the arc plate 6.4.1 to reduce the friction between the air duct conversion component 6.4 and the outer shell assembly forming the first air duct 6.3.2 or the second air duct 6.3.3 when blocking the first air duct 6.3.2 or the second air duct 6.3.3.

[0083] As shown in Figures 3 and 4, from the cross-section of the cleaning brush 6, the A-channel change node of the curved plate 6.4.1 is connected to the lower part of the first channel 6.3.2, and the B-channel change node is connected to the side of the third channel 6.3.4 near the second channel 6.3.3. At this time, the horizontal position of the B-channel change node is higher than that of the A-channel change node. At the same time, the C-scraper node 6.4.4 moves to the side of the second channel 6.3.3 (achieving the scraping of the small particles from the first channel 6.3.2 to the second channel 6.3.3 for suction when moving in the second direction). The first channel 6.3.2 opens, and the second channel 6.3.3 closes to complete the cleaning when moving forward. When moving in the second direction, the B-channel change node connects to the lower part of the second channel 6.3.3, and the A-channel change node connects to the side of the third channel 6.3.4 near the second channel 6.3.3. At this time, the horizontal position of the A-channel change node is higher than that of the B-channel change node. The D-scraper 6.4.4 node moves to the side of the first channel 6.3.2 (achieving the scraping of small particles from the second channel 6.3.3 to the first channel 6.3.2 for suction when moving in the first direction). The second channel 6.3.3 opens, and the first channel 6.3.2 closes, completing the cleaning process during the backward movement.

[0084] In some embodiments, the inner surface of the curved plate 6.4.1 is a smooth curved surface. When the first air duct 6.3.2 and the third air duct 6.3.4 are connected, the smooth curved surface can smoothly connect the first air duct 6.3.2 and the third air duct 6.3.4. When the second air duct 6.3.3 and the third air duct 6.3.4 are connected, the smooth curved surface can smoothly connect the second air duct 6.3.3 and the third air duct 6.3.4. The smooth curved surface of the inner surface of the curved plate 6.4.1 makes it less likely for dirt to accumulate at the connection point between the first air duct 6.3.2 or the second air duct 6.3.3 and the third air duct 6.3.4 when they are connected.

[0085] The curvature of the inner surface of the arc-shaped plate 6.4.1 corresponds to the curvature of the inner cavities of the first air duct 6.3.2, the second air duct 6.3.3, and the third air duct 6.3.4, ensuring a smooth transition of dirt and debris at the air duct conversion component 6.4 after the air ducts 6.3.2 and 6.3.3 are changed. The outer arc-shaped surface of the arc-shaped plate 6.4.1 incorporates a scraper 6.4.4 structure to reduce friction during movement while ensuring a tight seal. This reduces the friction area of ​​the air duct conversion component 6.4, ensuring smooth movement and a tight seal. Simultaneously, the scraper 6.4.4 removes any small particles remaining on the outer slideway, effectively preventing blockages and resulting in a better seal when the first air duct 6.3.2 and the second air duct 6.3.3 are closed.

[0086] In some embodiments, as shown in Figures 5, 6, and 7, the first rotating shaft 6.4.2 or the second rotating shaft 6.4.3 is connected to the drive component 6.5. A visualization window 6.4.5 is also provided on the first rotating shaft 6.4.2 or the second rotating shaft 6.4.3 connected to the drive component 6.5 to observe the connection status between the drive component 6.5 and the first rotating shaft 6.4.2 or the second rotating shaft 6.4.3. The drive component 6.5 can be a motor, and the motor can be a stepper motor capable of forward and reverse rotation. The visualization window 6.4.5 facilitates observation of whether the drive component 6.5 is installed correctly and also facilitates disassembly. The first rotating shaft 6.4.2 or the second rotating shaft 6.4.3 has a built-in travel limit tooth 6.4.7 to control the travel of the air duct conversion component 6.4.

[0087] In some embodiments, the housing assembly includes an upper housing assembly 6.1, a lower housing assembly 6.2, and a floor brush head 6.3.1. The upper housing assembly 6.1 is disposed on the lower housing assembly 6.2, and the lower housing assembly 6.2 is disposed on the floor brush head 6.3.1. The floor brush head 6.3.1 serves as the main frame for mounting the lower housing assembly 6.2 and the upper housing assembly 6.1.

[0088] The cleaning brush 6 also includes a mounting base 6.7, as shown in Figures 11, 12, and 13. The mounting base 6.7 is detachably mounted on the brush head 6.3.1, and a sealing ring 6.8 is provided between the mounting base 6.7 and the brush head 6.3.1 to prevent water leakage at this location. The mounting base 6.7 is hinged to the first pivot 6.4.2 and the second pivot 6.4.3 of the air duct conversion component 6.4, allowing the air duct conversion component 6.4 to move relative to the mounting base 6.7. By mounting the air duct conversion component 6.4 on the mounting base 6.7, which is detachably mounted on the housing assembly, the air duct conversion component 6.4 can be quickly disassembled.

[0089] In some embodiments, the first rotating shaft 6.4.2 and the second rotating shaft 6.4.3 are each provided with an annular protrusion 6.4.6 around the axis of the first rotating shaft 6.4.2 and the second rotating shaft 6.4.3. The two ends of the fixing seat 6.7 are provided with grooves 6.7.1 that respectively cooperate with the annular protrusion 6.4.6. The grooves 6.7.1 can be T-grooves. The annular protrusion 6.4.6 is placed in the groove 6.7.1 and moves under the guidance of the groove 6.7.1.

[0090] The mounting base 6.7 uses a double T-slot mounting system to secure the duct conversion component 6.4. The double T-slot positioning and guiding motion of the duct conversion component 6.4 saves space and provides excellent sealing during duct changes. The inner surface of the mounting base 6.7 corresponds to the outer arc surface of the duct conversion component 6.4, ensuring smooth movement of the component and reducing the chance of small particles accidentally entering the slide rail and affecting its operation.

[0091] The cooperation between the annular protrusion 6.4.6 and the groove 6.7.1 can achieve good positioning and guidance of the movement of the air duct switching component, so that the air duct switching component 6.4 can rotate stably and realize the switching of the connection between the first air duct 6.3.2, the second air duct 6.3.3 and the third air duct 6.3.4.

[0092] In some embodiments, a first soft scraper 6.6.1 is provided at one end of the first air duct 6.3.2 near the first roller brush 7; a second soft scraper 6.6.2 is provided at one end of the second air duct 6.3.3 near the second roller brush 8. The first soft scraper 6.6.1 and the second soft scraper 6.6.2 are respectively embedded at the ends of the air duct openings of the first air duct 6.3.2 and the second air duct 6.3.3, and the first soft scraper 6.6.1 and the second soft scraper 6.6.2 are in contact with the ground. The first soft scraper and the second soft scraper can be long and thin, with a length approximately equal to the axial length of the first roller brush 7 and the second roller brush 8. The soft scraper, in contact with the ground, can scrape away water stains and debris sucked up by the roller brush 6.4.4 when cleaning the ground.

[0093] The first air duct 6.3.2, the second air duct 6.3.3, the third air duct 6.3.4, the first soft scraper 6.6.1, and the second soft scraper 6.6.2 adopt an integrated structure. At the bottom of the air duct intersection, there is an air duct separation installation slot, which facilitates the direct installation of the air duct conversion component 6.4 and the drive component 6.5. The drive component 6.5 can be self-locking without installation screws. It is fixed and sealed by the slide rail support component, which greatly reduces the number of parts in the track changing transmission, improves the transmission matching accuracy, and facilitates installation, replacement, and maintenance.

[0094] This application embodiment also provides a cleaning device, as shown in FIG14. This cleaning device can be a dry suction device, such as a vacuum cleaner. It includes the cleaning brush 6 as described in any of the above embodiments, and also includes a main body component, which includes:

[0095] The body assembly 3 includes a mainboard 3.2, which controls the movement direction of the airflow conversion component 6.4 of the cleaning brush 6.

[0096] A handle assembly is mounted on the body assembly 3. The handle assembly may include a handle housing, a button control panel 1.2, and a lever 1.3. Buttons on the button control panel 1.2 are used for controlling the overall operating mode of the machine.

[0099] When the cleaning device is started via the switch on the control panel 1.2 on the handle, it is powered by the battery pack assembly 2.2, and the suction motor 2.5 starts. Simultaneously, the first roller brush 7 and the second roller brush 8 of the synchronous cleaning brush 6 rotate forward for cleaning. The main board 3.2 sends a signal to the drive component 6.5 of the air duct conversion component 6.4. The drive component 6.5 moves a certain angle, causing the air duct conversion component 6.4 to move a certain angle. The first air duct 6.3.2 connects to the third air duct 6.3.4 while simultaneously closing the second air duct 6.3.3. Under the cleaning action of the first roller brush 7, the main suction of the first air duct 6.3.2 cleans and sucks away dust and debris moving forward. When the dry cleaning equipment moves backward for cleaning, the main board 3.2 sends a signal to the air duct conversion component 6.4 and the drive component 6.5. The drive component 6.5 moves in the opposite direction at a certain angle, and the second air duct 6.3.3 connects to the third air duct 6.3.4 while closing the first air duct 6.3.2. Under the cleaning of the second roller brush 8, the dust and debris in the second direction are cleaned and sucked away by the main suction of the second air duct 6.3.3.

[0100] This dry suction device controls the forward and reverse movement of the air duct switching component 6.4 through the cleaning system, switching the connection and closing of the first air duct 6.3.2, the second air duct 6.3.3, and the third air duct 6.3.4 to achieve the set actions and complete the desired function.

[0101] This application embodiment also provides a cleaning device, as shown in FIG15. The cleaning device can be a floor scrubbing machine or other floor scrubbing equipment, including the cleaning brush 6 as described in any of the above embodiments, and also includes a main body component, which includes:

[0102] The body assembly 3 includes a mainboard 3.2, which controls the movement direction of the airflow conversion component 6.4 of the cleaning brush 6.

The wastewater tank assembly 4 may include a wastewater tank body 4.1 and a HEPA filter assembly 4.2 disposed at the top opening of the wastewater tank body 4.1 to filter dirt from the third air duct 6.3.4, especially large particles of debris and moisture.

[0106] The clean water tank assembly 5, which is mounted on the body assembly 3, is used to provide cleaning water for the cleaning equipment. For example, it can supply the cleaning equipment with the required electrolyzed water disinfectant.

[0107] When the floor cleaning equipment is started via the switch on the control panel 1.2 on the handle, it is powered by the battery pack 2.2. The suction motor 2.5 and the roller brush motor start, and the first roller brush 7 and the second roller brush 8 work simultaneously, moving forward to clean. The main board 3.2 sends a signal to the drive unit 6.5 of the air duct conversion component 6.4. The drive unit 6.5 moves a certain angle, causing the air duct conversion component 6.4 to move a certain angle as well. The first air duct 6.3.2 connects to the third air duct 6.3.4 while simultaneously closing the second air duct 6.3.3. The cleaning process continues as the first roller brush 7 cleans... Under the cleaning action of the first air duct 6.3.2, the main suction force removes dirt, sewage, and debris moving in the forward direction. When the floor cleaning equipment moves backward, the main board 3.2 sends a signal to the drive component 6.5 of the air duct conversion component 6.4. The drive component 6.5 moves in the opposite direction at a certain angle, and the second air duct 6.3.3 connects to the third air duct 6.3.4 while simultaneously closing the first air duct 6.3.2. Under the cleaning action of the second roller brush 8, the main suction force of the second air duct 6.3.3 removes dirt, sewage, and debris moving in the second direction.

[0108] This application embodiment also provides a cleaning system, as shown in Figures 16 and 17. The cleaning system includes cleaning equipment and a base station 9. The base station 9 includes a fan and a hot air duct. The fan may include a first fan 9.6 and a second fan 9.7. The hot air duct has a first hot air outlet 9.1 and a second hot air outlet 9.2. A first air pressure plate 9.3 is provided above the first hot air outlet 9.1, and a second air pressure plate 9.4 is provided above the second hot air outlet 9.2, so that the first hot air outlet 9.1 and the second hot air outlet 9.2 converge toward one end of the first roller brush 7 and the second roller brush 8, thereby increasing the airflow and improving the drying effect. When the cleaning equipment is placed on the base station 9 and dried, the air duct conversion component 6.4 of the cleaning brush 6 moves to a preset position, and the fan and the sub-unit assembly 2 provide suction so that the first air duct 6.3.2 and the second air duct 6.3.3 of the cleaning brush 6 are connected to the third air duct 6.3.4. This allows the fan to blow hot air out through the first hot air port 9.1 and the second hot air port 9.2, and blow it through the hot air duct to the first air duct 6.3.2, the second air duct 6.3.3 and the third air duct 6.3.4 of the cleaning brush 6.

[0109] When the floor cleaning equipment is placed on base station 9 and self-cleaning is activated via the handle switch, the main board 3.2 sends a signal to control the air duct conversion component 6.4 and the drive component 6.5. The drive component 6.5 moves at a certain angle, causing the air duct conversion component 6.4 to move at a certain angle. The first air duct 6.3.2 connects to the third air duct 6.3.4, while the second air duct 6.3.3 remains closed. The main suction force of the first air duct 6.3.2 cleans and sucks away the dirt, sewage, particles, etc. remaining on the first roller brush 7. When the mainboard 3.2 sends a signal to control the air duct conversion component 6.4 and the drive component 6.5, the drive component 6.5 moves in the opposite direction by a certain angle. Under the action of the drive component 6.5, the air duct conversion component 6.4 moves in the opposite direction by a certain angle. The second air duct 6.3.3 connects to the third air duct 6.3.4, while the first air duct 6.3.2 remains closed. The main suction force of the second air duct 6.3.3 cleans and sucks away the dirt, sewage, particles and other residues remaining on the second roller brush 8. During the self-cleaning process, the air duct conversion component 6.4 is controlled by the program to change the direction of the air duct movement in a cycle, thus completing the self-cleaning process.

[0110] When the floor cleaning equipment enters the drying mode on base station 9, the main board 3.2 sends a signal to control the air duct conversion component 6.4 and the drive component 6.5. The drive component 6.5 moves at a certain angle, causing the air duct switching component to move at a certain angle, so that the A conversion node and the B conversion node are at similar heights. The first air duct 6.3.2, the second air duct 6.3.3 and the third air duct 6.3.4 are simultaneously connected, and the first fan 9.6 and the second fan 9.7 inside base station 9 blow hot air out through the first hot air port 9.1 and the second hot air port 9.2 to form a co-current circulation. The suction motor 2.5 of the machine body is the main force, and the hot air fan of base station 9 is the auxiliary force, which sucks away the water vapor formed by the residual moisture of the first roller brush 7 and the second roller brush 8, achieving a highly efficient drying effect.

[0111] This floor cleaning equipment controls the forward and reverse movement of the air duct conversion component 6.4 through the cleaning system, changing the connection and closing of the first air duct 6.3.2, the second air duct 6.3.3, and the third air duct 6.3.4 to achieve the set actions and complete the desired function.
