Description

Technical Field

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

[0002] Vacuum cleaners, floor scrubbers and other cleaning equipment are widely used for environmental cleaning in various indoor and outdoor scenarios. Different cleaning equipment can perform various functions such as vacuuming and mopping, thereby maintaining a clean and tidy living and working environment.

[0003] In related technologies, cleaning equipment typically uses floor brushes to clean floors. Floor brushes clean floors by vacuuming, scraping, and rinsing. During the cleaning process, dirt and debris may stick to the brush parts, requiring cleaning.

[0004] However, currently, floor brushes need to be cleaned at designated locations such as faucets or cleaning base stations, which is time-consuming and labor-intensive. Utility Model Content

[0005] This application provides a floor brush device to solve the technical problem that current floor brushes need to be cleaned at designated locations such as faucets or cleaning base stations, which is time-consuming and labor-intensive.

[0006] This application provides a floor brush device, which includes a device body and a cleaning component. The device body has a floor brush air duct, and the cleaning component is connected to the device body.

[0007] The cleaning assembly includes a cleaning body, a first water spray module, and a second water spray module. The cleaning body has an air suction chamber that is open to the bottom of the device body and is connected to the floor brush air duct. The first water spray module and the second water spray module are both located on the cleaning body. The first water spray module is configured to spray cleaning water onto the surface to be cleaned below the cleaning body, and the second water spray module is configured to spray cleaning water into the air suction chamber.

[0008] The floor brush device has a cleaning mode and a self-cleaning mode. In the cleaning mode, at least the first water spray module sprays cleaning water. In the self-cleaning mode, only the second water spray module sprays cleaning water.

[0009] The floor brush device provided in this application can switch between a cleaning mode and a self-cleaning mode. During cleaning, the device switches to cleaning mode, using the first water spray module to spray water onto the surface to be cleaned, and cooperating with related components to scrape and vacuum the surface to achieve a cleaning effect. After cleaning, the device switches to self-cleaning mode, the first water spray module turns off, and the second water spray module sprays water into the suction chamber to complete self-cleaning. By switching between cleaning and self-cleaning modes, the floor brush device can complete either cleaning or self-cleaning without needing to go to a faucet or cleaning station for cleaning, saving time and effort.

[0010] As an optional implementation, the floor brush duct has an air inlet, and the cleaning body is located below the air inlet; the cleaning body has a suction port, and the suction chamber is connected to the air inlet through the suction port.

[0011] With this setup, the air inlet can provide negative pressure suction, allowing the suction port to absorb debris and wastewater from the surface to be cleaned, improving the cleaning effect and reducing residual water stains on the surface.

[0012] As an optional implementation, along the cleaning direction of the floor brush device, the cleaning component has a cleaning chamber on the rear side of the suction chamber, and the cleaning chamber is connected to the air inlet through the suction port; the first water spray module is used to spray cleaning water onto the surface to be cleaned corresponding to the cleaning chamber.

[0013] With this setup, when the floor brush moves along the cleaning direction, the suction chamber can first perform a rough suction on the surface to be cleaned, sucking in dust and debris, and then the cleaning chamber can perform a fine cleaning on the surface to be cleaned, removing stubborn stains. The combination of the two improves cleaning efficiency.

[0014] As an optional implementation, the cleaning assembly further includes a first scraping assembly and a second scraping assembly, both of which are connected to the cleaning body and are spaced apart along the cleaning direction of the floor brush device.

[0015] When the floor brush device cleans the surface to be cleaned, the lower edges of both the first scraping component and the second scraping component are in contact with the surface to be cleaned, and a cleaning cavity is formed between the first scraping component and the second scraping component.

[0016] With this configuration, when the floor brush device moves forward or backward, the first or second scraping component can scrape the surface to be cleaned to remove stains and water stains, which can improve cleaning efficiency and speed up the drying of the surface to be cleaned.

[0017] As an alternative implementation, the suction port is at least partially located on the top wall of the air suction chamber, and the cleaning water sprayed by the second water spray module flows along the top wall of the air suction chamber to the suction port.

[0018] With this configuration, the suction port can draw in the cleaning water sprayed from the second water spray module, preventing the cleaning water from dripping.

[0019] As an optional implementation, the cleaning body extends along the width direction of the device body, the suction chamber extends along the width direction of the device body, and the length of the suction chamber matches the width of the device body.

[0020] The second water spray module has a water outlet, and the water outlet and the sewage suction port are located at different positions along the length of the air suction chamber.

[0021] This design, with the cleaning body and suction chamber extending along the width of the device and matching in length, allows the cleaning equipment to cover a larger cleaning area in a single movement, reducing the number of times the cleaning equipment needs to be moved and improving cleaning efficiency.

[0022] As an optional implementation, there are at least two water outlets, which are distributed at both ends of the suction chamber along its length, and the sludge suction port is located in the middle of the suction chamber along its length, so that the cleaning water sprayed from the water outlets flows from both ends of the suction chamber along the chamber wall to the sludge suction port.

[0023] With this design, the cleaning water flows along the top wall of the suction chamber during the process of being drawn in, which can achieve the effect of cleaning the top wall of the suction chamber and improve the self-cleaning efficiency.

[0024] As an optional implementation, the floor brush device also includes a water supply component disposed on the main body of the device; the water supply component is configured to supply water to one of the first water spray module and the second water spray module, or to supply water to both the first water spray module and the second water spray module simultaneously.

[0025] With this setup, water can be selectively supplied through the water supply components, allowing switching between cleaning and self-cleaning modes.

[0026] As an optional implementation, the water supply assembly includes a water tank, a first water pump, and a second water pump. The inlet ends of both the first and second water pumps are connected to the water tank, the outlet end of the first water pump is connected to the first spray module, and the outlet end of the second water pump is connected to the second spray module.

[0027] This configuration allows for the control of the water pressure and flow rate of the first and second spray modules via the first and second water pumps, respectively, to meet different cleaning needs and improve cleaning flexibility.

[0028] As an optional implementation, the water supply assembly includes a water tank, a water pump, and a multi-way valve. The water pump's inlet is connected to the water tank, and the water pump's outlet is connected to the multi-way valve. The multi-way valve has at least two outlets, which are respectively connected to the first water spray module and the second water spray module. The multi-way valve can control the on / off state of each of its outlets.

[0029] With this setup, the water output of the first and second spray modules can be controlled via a multi-way water valve, enabling switching between cleaning and self-cleaning modes.

[0030] As an optional implementation, the bottom of the device body is provided with a receiving groove, and the cleaning components are detachably installed in the receiving groove.

[0031] This design allows for the disassembly of the cleaning components, facilitating the replacement of worn parts and the cleaning of the components themselves.

[0032] This application provides a floor brush device, comprising a main body and a cleaning component. The main body has a floor brush air duct, and the cleaning component is connected to the main body. The cleaning component includes a cleaning body, a first water spray module, and a second water spray module. The cleaning body has an air intake chamber open downwards towards the main body, and the air intake chamber is connected to the floor brush air duct. Both the first and second water spray modules are disposed on the cleaning body. The first water spray module is configured to spray cleaning water onto the surface to be cleaned below the cleaning body, and the second water spray module is configured to spray cleaning water into the air intake chamber. The floor brush device has a cleaning mode and a self-cleaning mode. In the cleaning mode, at least the first water spray module sprays cleaning water; in the self-cleaning mode, only the second water spray module sprays cleaning water. The floor brush device provided by this application can clean or self-clean the surface to be cleaned by switching between the cleaning mode and the self-cleaning mode, eliminating the need to go to a faucet or cleaning station for cleaning, saving time and effort.

[0049] To make the objectives, technical solutions, and advantages of the embodiments of this application clearer, the technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, not all embodiments. Based on the embodiments of this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application.

[0050] Vacuum cleaners, floor scrubbers and other cleaning equipment are widely used for environmental cleaning in various indoor and outdoor scenarios. Different cleaning equipment can perform various functions such as vacuuming and mopping, thereby maintaining a clean and tidy living and working environment.

[0051] In related technologies, cleaning equipment typically uses floor brushes to clean floors. Floor brushes clean floors by vacuuming, scraping, and rinsing. During the cleaning process, dirt and debris may stick to the brush parts, requiring cleaning.

[0052] However, currently, floor brushes are usually manually cleaned at a designated location or placed on a cleaning base station for cleaning after the cleaning work is completed. At the same time, there are a lot of stains and debris stuck to the surface during the cleaning process, which also requires going to a designated location for cleaning. After cleaning, the brushes are placed back on the ground for cleaning, which is time-consuming and laborious.

[0053] To address the aforementioned technical problems, this application provides a floor brush device that can switch between a cleaning mode and a self-cleaning mode to clean the surface to be cleaned or to self-clean itself, eliminating the need for repeated handling and cleaning, thus saving time and effort.

[0054] The following is an example illustrating the application scenarios of the floor brush device provided in the embodiments of this application.

[0055] The floor brush device provided in this application embodiment is applied in cleaning equipment and is a cleaning structure in the cleaning equipment that comes into contact with the surface to be cleaned. The types of products to which the floor brush device in this application embodiment can be applied may include, but are not limited to, vacuum cleaners, floor scrubbers, and robotic vacuum cleaners. Depending on the different product types, the cleaning equipment provided in this application embodiment can be used to clean various types of floors and other surfaces, and this application embodiment does not make any specific limitations in this regard.

[0056] Figure 1 This is a schematic diagram of the structure of the floor brush device provided in the embodiments of this application; Figure 2 This is a bottom schematic diagram of the floor brush device provided in the embodiments of this application; Figure 3 This is a schematic diagram of the structure of the cleaning component provided in the embodiments of this application; Figure 4 An exploded view of the cleaning component provided in the embodiments of this application; Figure 5 This is a schematic diagram of the structure of the first scraping component provided in an embodiment of this application; Figure 6 This is a schematic diagram of the structure of the second scraping component provided in an embodiment of this application.

[0057] See Figures 1 to 6 As shown, this application provides a floor brush device 10, which can move on the surface to be cleaned and clean it. The floor brush device 10 includes a device body 100 and a cleaning component 200. The device body 100 is used to carry different cleaning parts, and the cleaning component 200 is used to clean the surface to be cleaned. The cleaning component 200 is connected to the device body 100. The device body 100 is provided with a floor brush air duct 110. The device body 100 may also be provided with a suction element. The floor brush air duct 110 can be connected to the suction element. The suction element provides negative pressure suction, and the sucked-in garbage and sewage can enter the collection device through the floor brush air duct 110.

[0058] In some embodiments, the cleaning assembly 200 includes a cleaning body 210, a first water spray module 221, and a second water spray module 222. The cleaning body 210 has an air suction chamber 216 that is open to the lower part of the device body 100 and is connected to the floor brush duct 110. The first water spray module 221 and the second water spray module 222 are both disposed on the cleaning body 210. The first water spray module 221 is configured to spray cleaning water onto the surface to be cleaned below the cleaning body 210, and the second water spray module 222 is configured to spray cleaning water onto the air suction chamber 216.

[0059] It should be noted that the first water spray module 221 and the second water spray module 222 may be provided with a first water spray cover plate 2211 and a second water spray cover plate 2221. The first water spray cover plate 2211 and the second water spray cover plate 2221 are respectively provided with a first water inlet connector 2214 and a second water inlet connector 2223. The first water inlet connector 2214 and the second water inlet connector 2223 are both connected to the water supply component to provide cleaning water to the first water spray module 221 and the second water spray module 222. The first water spray module 221 may also be provided with a water spray housing 2212. The first water spray cover plate 2211 covers the water spray housing 2212. The water spray housing 2212 has a water spray chamber inside. The side of the water spray housing 2212 facing the surface to be cleaned is provided with a water spray function. The cleaning body 210 has at least two spray holes 2213. The spray holes 2213 are connected to the first water inlet connector 2214 through the spray chamber. The first spray module 221 can spray cleaning water onto the surface to be cleaned below the cleaning body 210 through the spray holes 2213 to clean the surface. The cleaning body 210 is provided with an integrally formed spray chamber. The second spray cover plate 2221 is covered on the spray chamber of the cleaning body 210. The top wall of the suction chamber 216 is provided with at least two water outlets 2222. The water outlets 2222 are connected to the second water inlet connector 2223 through the spray chamber of the cleaning body 210. The second spray module 222 sprays cleaning water onto the suction chamber 216 through the water outlets 2222 to clean the suction chamber 216.

[0060] For example, the number of water spray holes 2213 can be 2, 3, 6, 8, 10, etc., and the number of water outlets 2222 can be 2, 3, 6, 8, 10, etc., and this application embodiment does not make specific limitations. Among them, at least two water spray holes 2213 are located at both ends of the water spray housing 2212, and at least two water outlets 2222 are located at both ends of the air suction chamber 216.

[0061] In some embodiments, the floor brush device 10 has a cleaning mode and a self-cleaning mode; in the cleaning mode, at least the first water spray module 221 sprays cleaning water from the first water spray module 221 and the second water spray module 222; in the self-cleaning mode, only the second water spray module 222 sprays cleaning water.

[0062] Understandably, by controlling the water output of the first water spray module 221 and the second water spray module 222, the floor brush device 10 can be switched between cleaning mode and self-cleaning mode. When the floor brush device 10 is in cleaning mode, it moves along the surface to be cleaned, the first water spray module 221 sprays water onto the surface to be cleaned, and the second water spray module 222 may spray water to clean the suction chamber 216 or may not spray water. When the floor brush device 10 is in self-cleaning mode, it stops moving, the first water spray module 221 stops spraying water, and the second water spray module 222 sprays water onto the top wall of the suction chamber 216 to wash away dust, hair, and debris adhering to the suction chamber 216.

[0063] As one possible implementation, the floor brush duct 110 has an air inlet 111, and the cleaning body 210 is located below the air inlet 111; the cleaning body 210 has a suction port 211, and the suction chamber 216 is connected to the air inlet 111 through the suction port 211.

[0064] It is understandable that the main body 100 of the device may be equipped with a suction element. When the suction element is working, the air inlet 111 generates negative pressure suction, which allows the suction port 211 to suck up dust, hair, garbage and debris and cleaning wastewater from the surface to be cleaned, and enter the collection device through the floor brush air duct 110.

[0065] Reference Figure 1 and Figure 2 The direction of movement of the floor brush device 10 during cleaning is defined as the X direction, and the width direction of the floor brush device 10 is defined as the Y direction, which is perpendicular to the x-axis. Figure 1 The orientation of the paper is Y-axis, which is perpendicular to X-axis.

[0066] As one possible implementation, along the cleaning direction of the floor brush device 10, the cleaning component 200 has a cleaning chamber 215 on the rear side of the suction chamber 216, and the cleaning chamber 215 is connected to the air inlet 111 through the suction port 211; the first water spraying module 221 is used to spray cleaning water onto the surface to be cleaned corresponding to the cleaning chamber 215.

[0067] Understandably, along the cleaning direction, the cleaning chamber 215 is located behind the suction chamber 216. When the floor brush device 10 performs cleaning work, the suction chamber 216 first performs a coarse suction on the surface to be cleaned, sucking in dust, hair, and debris from the surface through the suction port 211. Then, the cleaning chamber 215 performs a fine wash on the surface to be cleaned, spraying cleaning water onto the surface to be cleaned corresponding to the cleaning chamber 215 through the first water spray module 221 to rinse the surface, and sucking in cleaning wastewater through the suction port 211 to achieve cleaning of the surface to be cleaned.

[0068] As one possible implementation, the cleaning component 200 also includes a first scraping component 223 and a second scraping component 224, both of which are connected to the cleaning body 210 and are distributed at intervals along the cleaning direction of the floor brush device 10.

[0069] It should be noted that the first scraping assembly 223 may include a first scraping plate 2232 and a first scraping strip 2233, and the second scraping assembly 224 may include a second scraping plate 2242 and a second scraping strip 2243. The first scraping plate 2232 and the first scraping strip 2233, the second scraping plate 2242 and the second scraping strip 2243 may be integrally formed, or they may be connected by bolts, clips or other means.

[0070] When the floor brush device 10 cleans the surface to be cleaned, the lower edges of the first scraping component 223 and the second scraping component 224 are in contact with the surface to be cleaned, and a cleaning cavity 215 is formed between the first scraping component 223 and the second scraping component 224.

[0071] It should be noted that the cleaning body 210 may have a vertically penetrating first mounting groove 213 and a second mounting groove 214. The first mounting groove 213 and the second mounting groove 214 are spaced apart and extend along the length of the cleaning body 210. The lengths of the first mounting groove 213 and the second mounting groove 214 may match the length of the cleaning body 210. The first scraping component 223 and the second scraping component 224 may be inserted into the first mounting groove 213 and the second mounting groove 214 respectively to achieve connection with the cleaning body 210.

[0072] As one possible implementation, the first scraper blade 2232 can be provided with multiple first slots 2231, and the first mounting groove 213 can be provided with multiple first engaging protrusions 2131 that match the first slots 2231. The upper and lower surfaces of the first engaging protrusions 2131 can be inclined towards the center to form two inclined surfaces. When the first scraping component 223 is inserted into the first mounting groove 213, the first scraping component 223 can slide into the first mounting groove 213 along the upper inclined surface of the first engaging protrusions 2131 until the first engaging protrusions 2131... The first slot 2231 engages with the first slot 2231, and the first engaging protrusion 2131 can limit the first scraping component 223 to prevent it from falling off or loosening during the cleaning process. When the first scraping component 223 is disassembled, an upward force is applied to the first scraping component 223 to make the first slot 2231 slide out along the lower inclined surface of the first engaging protrusion 2131. At this time, the first slot 2231 and the first engaging protrusion 2131 are disengaged, so that the first scraping component 223 can be taken out from the first mounting groove 213.

[0073] Similarly, the second scraper 2242 may be provided with multiple second slots 2241, and the second mounting groove 214 may be provided with multiple second snap-fit ​​protrusions 2141 that match the second slots 2241. The second slots 2241 and the second snap-fit ​​protrusions 2141 are snapped together in the same manner as described above.

[0074] Understandably, after the first scraping assembly 223 and the second scraping assembly 224 are connected to the cleaning body 210, a cleaning cavity 215 is formed between the first scraping assembly 223 and the second scraping assembly 224. The first water spray module 221 can spray water into the surface to be cleaned in the cleaning cavity 215 to rinse the surface and remove stubborn stains and adhered debris. The first scraper 2233 and the second scraper 2243 of the first scraping assembly 223 and the second scraper 2243 can make interference contact with the surface to be cleaned and deform, scraping away debris, stains, and water stains from the surface to be cleaned through friction. The first scraper 2233 and the second scraper 2243 can be made of elastic materials such as rubber and silicone.

[0075] It should be noted that the first water spray assembly 220 sprays water onto the surface to be cleaned in the cleaning chamber 215 through the water spray holes 2213. For example, there can be four water spray holes 2213, which are equidistantly arranged along the length of the water spray housing 2212, with two water spray holes 2213 located at both ends of the water spray housing 2212. When the floor brush device 10 performs cleaning work, water is sprayed from the four water spray holes 2213 onto the surface to be cleaned in the cleaning chamber 215. At the same time, the air inlet 111 generates negative pressure suction, so that the suction port 211 connected to the air inlet 111 can suck in the cleaning wastewater. As the floor brush device 10 moves, residual water stains can be scraped off by the first scraper 2233 or the second scraper 2243.

[0076] Understandably, during the cleaning process, on the one hand, the jets sprayed from the four water nozzles 2213 can directly rinse a portion of the surface to be cleaned; on the other hand, the cleaning water sprayed from the two water nozzles 2213 at both ends of the water spray housing 2212 will flow towards the central suction port 211 under the influence of airflow. During the water flow, the surface to be cleaned can be rinsed along the length of the cleaning chamber 215, and debris can be carried to the suction port 211, so that areas that cannot be directly rinsed by the jets from the water nozzles 2213 can also be rinsed by the water flow.

[0077] As one possible implementation, the suction port 211 is at least partially located on the top wall of the suction chamber 216, and the cleaning water sprayed by the second water spray module 222 flows along the top wall of the suction chamber 216 to the suction port 211.

[0078] Understandably, when the ground brush device 10 is performing cleaning work or has stopped working, the second water spray module 222 can spray cleaning water into the suction chamber 216 to perform self-cleaning of the suction chamber 216. During the self-cleaning process, the suction element of the second water spray module 222 is in working state so that the suction port can generate negative pressure suction, so that the suction port 211 can directly suck in the self-cleaning wastewater. The water output speed of the second water spray module 222 can be adjusted. The water output speed is slower during self-cleaning to prevent the cleaning wastewater from dripping onto the surface to be cleaned.

[0079] In some embodiments, the suction port 211 may include a first suction port 211a, a second suction port 211b, and a third suction port 211c; the first suction port 211a is connected to the air suction chamber 216, the second suction port 211b is located between the first water spray module 221 and the first scraping assembly 223, and the first suction port 211a and the second suction port 211b are separated by the first scraping assembly 223; the third suction port 211c is located between the second scraping assembly 224 and the first water spray module 221. When the floor brush device 10 cleans along the cleaning direction, the first suction port 211a is used to suck up dust, hair and particulate matter, and the second suction port 211b and the third suction port 211c are used to suck up cleaning wastewater and small particulate matter in the cleaning chamber 215. The cross-sectional width of the first suction port 211a is greater than the cross-sectional width of the second suction port 211b and the third suction port 211c. The second suction port 211b and the third suction port 211c are flat suction ports, which have greater suction power under the same suction power and can suck up residual water stains on the surface to be cleaned. The design of the double suction ports in the cleaning chamber 215 can ensure that there are suction ports to suck up cleaning wastewater or water stains in time when the floor brush device 10 moves forward or backward, so that the surface to be cleaned dries quickly.

[0080] It should be noted that the top of the first scraping assembly 223 has a ventilation notch, with the first suction port 211a and the second suction port 211b connected to both sides of the ventilation notch. The first suction port 211a draws in cleaning water sprayed from the first water spray module 221, as well as dust, hair, and large particles of debris from the surface to be cleaned. When there is a lot of debris on the surface, the ventilation notch 225 at the top of the first scraping assembly 223 can increase the airflow of the first suction port 211a, allowing some debris to be drawn into the second suction port 211b through the ventilation notch 225, thereby improving the absorption efficiency.

[0081] As one possible implementation, the cleaning body 210 extends along the width direction of the device body 100, the suction cavity 216 extends along the width direction of the device body 100, and the length of the suction cavity 216 matches the width of the device body 100.

[0082] Understandably, the design of the cleaning body 210 and the suction chamber 216 extending along the width of the device body 100 and matching in length allows the cleaning equipment to cover a larger cleaning area in one movement, reducing the number of times the cleaning equipment needs to be moved and improving cleaning efficiency.

[0083] In some embodiments, the second water spray module 222 has a water outlet 2222. The water outlet 2222 and the suction port 211 are located at different positions along the length of the air suction chamber 216. After water is discharged from the water outlet 2222, it flows along the top wall of the air suction chamber 216 to the suction port 211, which can clean the top wall of the air suction chamber 216 along the way.

[0084] As one possible implementation, there are at least two water outlets 2222, which are distributed at both ends of the length of the air suction chamber 216, and the sewage suction port 211 is located in the middle of the length of the air suction chamber 216, so that the cleaning water sprayed from the water outlets 2222 flows from both ends of the air suction chamber 216 along the cavity wall of the air suction chamber 216 to the sewage suction port 211.

[0085] Understandably, the suction chamber 216 guides the airflow. Extending along the length of the cleaning body 210, the suction chamber 216 allows debris and impurities on the surface to be cleaned to be lifted by the airflow and enter the suction port 211. During self-cleaning, the water pump supplies water to the second spray module 222. Water enters the second spray chamber from the inlet and flows from the outlet 2222 to the suction chamber 216. At least two outlets 2222 are located at opposite ends of the suction chamber 216. With both ends connected to the outside, when the suction port 211 draws air, the airflow rushes in from both ends of the suction chamber 216 and flows into the central suction port 211 along the suction chamber 216. The water flow from the outlets 2222 at both ends of the suction chamber 216 is sprayed onto the cavity wall of the suction chamber 216 and flows along the cavity wall of the suction chamber 216 with the airflow, and is drawn in by the central suction port 211. While the water flow on both sides flows towards the central suction port 211, it can flush the cavity wall of the suction chamber 216, thereby achieving self-cleaning of the entire cavity wall of the suction chamber 216.

[0086] As one possible implementation, the floor brush device 10 also includes a water supply component disposed on the device body 100; the water supply component is configured to supply water to one of the first water spray module 221 and the second water spray module 222, or to supply water to both the first water spray module 221 and the second water spray module 222 simultaneously.

[0087] It should be noted that when the ground brush device 10 is in cleaning mode, the water supply component can spray water to the first water spray module 221 alone, or it can simultaneously supply water to the first water spray module 221 and the second water spray module 222; when the ground brush device 10 is in self-cleaning mode, the water supply component supplies water to the second water spray module 222 alone.

[0088] As one possible implementation, the water supply assembly includes a water tank, a first water pump, and a second water pump. The inlet ends of both the first and second water pumps are connected to the water tank, the outlet end of the first water pump is connected to the first spray module 221, and the outlet end of the second water pump is connected to the second spray module 222.

[0089] It should be noted that the first and second water pumps operate independently. The first and second water pumps can control the water pressure and flow rate of the first spray module 221 and the second spray module 222 according to actual needs. For example, when the floor brush device 10 switches to self-cleaning mode, the first water pump is turned off, and the second water pump controls the second spray module 222 to spray water onto the upper wall of the suction chamber 216 at a lower water pressure. This achieves a self-cleaning effect while preventing water from splashing into the surrounding environment.

[0090] As one possible implementation, the water supply assembly includes a water tank, a water pump, and a multi-way valve. The water pump's inlet is connected to the water tank, and the water pump's outlet is connected to the multi-way valve. The multi-way valve has at least two outlets, which are respectively connected to the first water spray module 221 and the second water spray module 222. The multi-way valve can control the on / off state of each of its outlets.

[0091] It is understandable that the multi-way water valve has at least two water outlets, and at least two water outlets are respectively connected to the first water spray module 221 and the second water spray module 222. The multi-way water valve can be controlled by a solenoid valve or a mechanical valve core to achieve independent on / off of the water outlets.

[0092] In some embodiments, the first water spray module 221 and the second water spray module 222 can be connected to the outlet of a plurality of multi-way water valves, so that the first water pump and the second water pump can simultaneously supply water to the first water spray module 221 or the second water spray module 222, thereby increasing the outlet pressure and outlet flow of the first water spray module 221 or the second water spray module 222 to enhance the cleaning effect.

[0093] As an optional implementation, the bottom of the device body 100 is provided with a receiving groove 120, and the cleaning component 200 is detachably disposed in the receiving groove 120.

[0094] For example, the cleaning body 210 and the device body 100 can be connected by a snap-fit ​​mechanism. The cleaning body 210 has a snap-fit ​​part 212, the top of which has a snap-fit ​​protrusion 2121. The two end walls of the receiving groove 120 have snap-fit ​​holes. When the cleaning body 210 is installed, it is inserted into the receiving groove 120 from bottom to top. During the insertion process, the snap-fit ​​part 212 abuts against the two end walls of the receiving groove 120, and the snap-fit ​​part 212 undergoes elastic deformation. When the snap-fit ​​part 212 reaches the snap-fit ​​hole, it returns to its original shape, and the snap-fit ​​protrusion 2121 slides into the snap-fit ​​hole to achieve a secure snap-fit. When disassembling, the snap-fit ​​protrusions 2121 on both sides are pressed at the same time to disengage them from the snap-fit ​​holes. At this time, the cleaning body 210 can be pulled out of the receiving groove 120 to complete the disassembly.

[0095] This application provides a floor brush device 10, which includes a device body 100 and a cleaning component 200. The device body 100 has a floor brush air duct 110, and the cleaning component 200 is connected to the device body 100. The cleaning component 200 includes a cleaning body 210, a first water spray module 221, and a second water spray module 222. The cleaning body 210 has a suction chamber 216 that is open towards the lower part of the device body 100 and communicates with the floor brush air duct 110. The first water spray module 221 and the second water spray module 222... All modules 222 are disposed on the cleaning body 210. The first water spray module 221 is configured to spray cleaning water onto the surface to be cleaned below the cleaning body 210, and the second water spray module 222 is configured to spray cleaning water into the suction chamber 216. The floor brush device 10 has a cleaning mode and a self-cleaning mode. In the cleaning mode, at least the first water spray module 221 sprays cleaning water; in the self-cleaning mode, only the second water spray module 222 sprays cleaning water. The floor brush device 10 provided in this application can clean or self-clean the surface to be cleaned by switching between the cleaning mode and the self-cleaning mode, eliminating the need to go to a faucet or cleaning station for cleaning, saving time and effort.
