Description
Technical Field
[0001] This application relates to the field of cleaning product technology, and more particularly to a floor brush device and cleaning equipment. Background Technology
[0002] Vacuum cleaners, floor scrubbers, and robotic vacuum cleaners are common household cleaning devices. Many of these devices offer multiple functions, including vacuuming and mopping.
[0003] In related technologies, cleaning equipment with vacuuming and mopping functions typically uses a floor brush to clean the floor. The floor brush is equipped with a roller brush and a water tank. The water tank supplies cleaning water to wet the roller brush, and the wet roller brush rolls on the floor to achieve a wet mopping cleaning effect. In addition, a suction port is set on the floor brush to suck up garbage and debris on the floor, as well as wastewater scraped off from the roller brush.
[0004] However, currently, after cleaning equipment finishes cleaning, water stains remain on the roller brush parts of the floor brush, which makes the floor brush prone to producing odors. Utility Model Content
[0005] This application provides a floor brush device and cleaning equipment to solve the technical problem that water stains remain on the roller brush part of the current floor brush after cleaning, which makes the floor brush prone to producing odor.
[0006] In a first aspect, this application provides a floor brush device, which includes a device body, a wiping assembly and a spraying assembly; the floor brush device has a floor brush air duct, as well as a first suction port and a second suction port; the first suction port and the second suction port both face downwards from the device body and are both connected to the floor brush air duct.
[0007] The device has a partition at the bottom of its main body; a first suction port is located on the front side of the partition along a first direction, and a second suction port is located on the rear side of the partition along the first direction; a squeegee assembly is located on the rear side of the second suction port along the first direction; a water spray assembly is located between the partition and the second suction port, and the water spray assembly is configured to spray water toward the area facing the second suction port; wherein, the first direction is the cleaning direction of the floor brush device.
[0008] The floor brush device provided in this application features a first and a second suction port at the bottom, positioned one in front of the other along the cleaning direction. A separator separates the first and second suction ports, and a water spray component wets the floor facing the second suction port. During cleaning, large particles are blocked by the separator and sucked into the first suction port. Smaller dust particles pass under the separator and are sucked into the second suction port. The second suction port creates a strong negative pressure, drawing the wetted wastewater into the floor brush duct. As the cleaning water passes through the floor and is drawn into the second suction port, it carries away dust and stains, effectively separating particles of varying sizes for efficient cleaning. This method eliminates the need for a roller brush, prevents wastewater residue on the floor brush device, and avoids unpleasant odors after cleaning.
[0009] As an optional implementation, the water spray assembly is connected to the separator; the gap between the outer wall of the water spray assembly on the side away from the separator and the wiper assembly forms a second suction port.
[0010] With this configuration, the second suction port can be close to the partition, while the water spraying assembly sprays water between the second suction port and the partition to ensure that the second suction port has sufficient suction force on the area wetted by the water spraying assembly, thereby improving the efficiency of sewage suction.
[0011] As an optional implementation, the wiper assembly may include a wiper blade and a wiping element. A suction channel is formed between the wiper blade and the outer wall of the spray assembly, and the suction channel is connected to the floor brush air duct. The wiping element is connected to the wiper blade, and there is a gap between the wiping element and the outer wall of the spray assembly to form a second suction port, which is connected to the suction channel.
[0012] This configuration creates a second suction port through the gap between the scraper and the water spray assembly, resulting in a flat structure that increases the negative pressure suction that the second suction port can generate.
[0013] As an alternative implementation, the wiping component is inclined forward in a first direction relative to the vertical direction, and the sidewall of the water spray assembly facing the wiping component is inclined forward in a first direction.
[0014] This configuration allows the second suction port to be tilted towards the front of the floor brush device's cleaning direction, enabling it to suck in wastewater in the direction the floor brush device is moving, resulting in higher wastewater suction efficiency.
[0015] As an optional implementation, the lower edge of the separator extends along the width direction of the device body; in the vertical direction, the lower edge of the scraper is lower than the lower edge of the separator, so that when the scraper contacts the surface to be cleaned, there is a gap between the lower edge of the separator and the surface to be cleaned.
[0016] This design serves two purposes: firstly, it avoids water stains during the cleaning process; secondly, it allows dust and small particles on the floor to pass under the divider and be sucked in by the second suction port.
[0017] As an optional implementation, the height difference between the lower edge of the scraper and the lower edge of the separator is smaller than the gap between the scraper and the outer wall of the water spray assembly.
[0018] This setup ensures the unobstructed flow of the second suction port and prevents it from becoming clogged.
[0019] As an alternative implementation, the water spray assembly has a protrusion on the side facing the scraper, and the protrusion abuts against the scraper inside the second suction port.
[0020] This design prevents the gap between the scraper and the water spray assembly from closing under negative pressure suction, thus ensuring smooth airflow from the second suction port.
[0021] As an optional implementation, the second suction port extends along the width direction of the device body; there are multiple protrusions, which are arranged at intervals along the extension direction of the second suction port.
[0022] This design provides support at all points along the length of the second suction port, ensuring smooth airflow.
[0023] As an optional implementation, the width of the protrusion at the outer end of the second suction port is greater than the width of the protrusion at the inner end of the second suction port.
[0024] This design reduces airflow loss during the process of flowing into the first inlet.
[0025] As an alternative implementation, the sidewall of the protrusion facing the outside of the second suction port can be arc-shaped.
[0026] This design guides the airflow entering the first inlet, improving airflow smoothness.
[0027] As an optional implementation, the end of the wiper assembly away from the second suction port has an air outlet, which connects the second suction port and the floor brush duct. A flow guide structure is provided between the wiper assembly and the water spray assembly, and the flow guide structure is opposite to the air outlet.
[0028] With this configuration, when the airflow between the wiper assembly and the spray assembly converges at the air outlet, the airflow guide structure directs the airflow to avoid turbulence and reduce airflow loss.
[0029] As an optional implementation, the flow guiding structure may include a first flow guiding part and a second flow guiding part, wherein the first flow guiding part is connected to the wiper assembly, and the second flow guiding part is connected to the outer side wall of the water spray assembly; the first flow guiding part and the second flow guiding part are opposite to and abut against each other.
[0030] With this configuration, the airflow guide structure can be formed together when the wiper assembly and the water spray assembly are assembled, ensuring that the upper and lower ends of the airflow guide structure can be supported between the wiper assembly and the water spray assembly.
[0031] As an optional implementation, the water spray assembly may include a water spray body and a water spray cover. The water spray body is connected to a separator, and the water spray cover is connected to the side of the water spray body facing the wiper assembly. The water spray cover and the water spray body enclose a water spray cavity, and the water spray cover is provided with water spray holes that communicate with the water spray cavity. The water spray holes spray water towards the lower part of the device body.
[0032] This configuration improves the wetting efficiency of the area facing the ground from the second suction port.
[0033] As an optional implementation, the water spray hole is located at the lower edge of the water spray cover, and the water spray hole is located on the front side of the second suction port along the first direction.
[0034] This design allows the water flow to effectively and efficiently clean the ground during the process of the second suction port drawing in cleaning water.
[0035] As an optional implementation, the floor brush duct has an air inlet and an air outlet, with the air inlet forming a first suction port; the floor brush device also includes a suction pipe connected to the air outlet; and a second suction port is connected between the air inlet and the air outlet.
[0036] This design allows the garbage, debris, and water stains sucked in by the first and second suction ports to be collected and gathered in the storage space.
[0037] As an alternative implementation, the main body of the device may include a duct housing, which forms a floor brush duct.
[0038] In this configuration, at least a portion of the sidewall of the duct housing along the rear side in the first direction forms a partition; or, the partition is connected to the sidewall of the duct housing along the rear side in the first direction.
[0039] This configuration ensures the compactness of the floor brush device structure and improves space utilization.
[0040] Secondly, this application provides a cleaning device, which includes a main body and a floor brush device as described above, the floor brush device being movably connected to the main body.
[0041] This application provides a floor brush device and cleaning equipment. The floor brush device includes a main body, a squeegee assembly, and a spray assembly. The floor brush device has a floor brush air duct, a first suction port, and a second suction port. Both the first and second suction ports face downwards from the main body and are connected to the floor brush air duct. A partition is provided at the bottom of the main body. The first suction port is located on the front side of the partition along a first direction, and the second suction port is located on the rear side of the partition along the first direction. The squeegee assembly is disposed on the rear side of the second suction port along the first direction. The spray assembly is disposed between the partition and the second suction port and is configured to spray water towards the area facing the second suction port. The first direction is the cleaning direction of the floor brush device, thereby achieving the separation of particles of varying sizes and achieving a good cleaning effect. This method eliminates the need for a roller brush, prevents wastewater residue on the floor brush device, and avoids the generation of odors when the floor brush device is placed after cleaning.

[0054] In the description of this application, it should be noted that, unless otherwise expressly specified and limited, the terms "installation," "connection," and "linking" should be interpreted broadly.

Therefore, they should not be construed as limitations on this application.
[0056] The terms "first," "second," and "third" (if any) in the specification, claims, and accompanying drawings of this application are used to distinguish similar objects and are not necessarily used to describe a particular order or sequence. It should be understood that such data can be interchanged where appropriate so that the embodiments of this application described herein can be implemented in orders other than those illustrated or described herein.
[0057] Furthermore, the terms “comprising” and “having”, and any variations thereof, are intended to cover non-exclusive inclusion, such as a process, method, system, product, or maintenance tool that includes a series of steps or units, not necessarily limited to those steps or units that are explicitly listed, but may include other steps or units that are not explicitly listed or that are inherent to such process, method, product, or maintenance tool.
[0058] 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.
[0059] Cleaning equipment with vacuuming and mopping functions typically uses a floor brush to clean floors. The floor brush is equipped with a roller brush and a water tank. The water tank supplies water to wet the roller brush, which then rolls on the floor to achieve a wet mopping effect. The floor brush usually also has a suction port to suck up debris and wastewater scraped off the roller brush.
[0060] However, in current cleaning equipment, the roller brush on the floor brush is usually wrapped with a cleaning component that easily absorbs water. During the cleaning process, the cleaning component is squeezed by the scraper to remove the absorbed sewage. However, the water cannot be completely removed. After cleaning is completed, water stains will remain on the roller brush. If the cleaning component on the roller brush is not removed and dried in time, the floor brush is prone to odor or even mold.
[0061] To address the aforementioned technical problems, this application provides a floor brush device and cleaning equipment. It eliminates the roller brush structure on the floor brush and uses different suction ports to divert and clean large debris and wastewater stains. Furthermore, the design of the different suction port layout positions allows the suction port for wastewater stains to generate greater suction power. During the cleaning process, cleaning water is sprayed or dripped onto the area facing the suction port, and the suction power of the port draws in the wastewater from the surface to be cleaned. Thus, as the cleaning water enters the suction port from the surface to be cleaned, it removes dust and stains, improving cleaning efficiency. Moreover, after cleaning, there is no need for drying, and no odor is produced.
[0062] The following section provides examples illustrating the application scenarios of the floor brush device and cleaning equipment provided in the embodiments of this application.
[0063] 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 product type of the cleaning equipment in this application embodiment may include, but is 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. This application embodiment does not make any specific limitations in this regard.
[0064] Figure 1 This is a schematic diagram of the structure of the cleaning equipment provided in the embodiments of this application; Figure 2 This is a schematic diagram of the structure of the floor brush device provided in the embodiments of this application; Figure 3 for Figure 2 A partial schematic diagram of position A in the middle; Figure 4 This is a schematic diagram illustrating the cooperation between the squeegee assembly and the spray assembly in the floor brush device provided in the embodiments of this application.
[0065] See Figures 1 to 4 As shown, this application provides a floor brush device 100 for use in a cleaning device 10. The floor brush device 100 includes a device body 110, a squeegee assembly 120, and a water spray assembly 130. The squeegee assembly 120 and the water spray assembly 130 are mounted on the device body 110. During the floor cleaning process, the device body 110 can move along the floor, the water spray assembly 130 is used to wet the floor, and the squeegee assembly 120 can scrape away the water stains on the wet floor.
[0066] The floor brush device 100 includes a floor brush duct 111, a first suction port 101, and a second suction port 102. Both the first suction port 101 and the second suction port 102 face downwards from the main body 110 and are connected to the floor brush duct 111. When the floor brush device 100 performs cleaning operations, a negative pressure airflow is generated in the floor brush duct 111, causing the first suction port 101 and the second suction port 102 to generate negative pressure suction. Dust, debris, and wastewater stains sucked in by the first suction port 101 and the second suction port 102 can enter the floor brush duct 111 for collection and storage.
[0067] Define the first direction as the cleaning direction of the floor brush device 100, such as... Figure 2 As shown, the first direction is the X direction, and the floor brush device 100 can move along the X direction during the cleaning process. Of course, the floor brush device 100 can also turn during the cleaning process, and the cleaning direction here is based on the structure of the floor brush device 100 itself.
[0068] In some embodiments, a partition 150 is provided at the bottom of the device body 110. A first suction port 101 is located on the front side of the partition 150 along a first direction, and a second suction port 102 is located on the rear side of the partition 150 along the first direction. A wiper assembly 120 is disposed on the rear side of the second suction port 102 along the first direction. A water spray assembly 130 is disposed between the partition 150 and the second suction port 102, and the water spray assembly 130 is configured to spray water toward the area facing the second suction port 102.
[0069] Understandably, the first suction port 101 and the second suction port 102 are distributed at intervals along the X direction at the bottom of the floor brush device 100, with the first suction port 101 in front and the second suction port 102 behind. During the forward cleaning process of the floor brush device 100, the first suction port 101 can first suck in dust, hair, and particulate matter. Among them, large debris is blocked by the separator 150 and is sucked into the floor brush air duct 111 through the first suction port 101 as the floor brush device 100 moves. The remaining dust and stubborn stains on the ground are not blocked by the separator 150. As the water spray component 130 wets the ground, the remaining small particulate matter and sewage stains can be sucked into the floor brush air duct 111 through the second suction port 102.
[0070] Since the water spray assembly 130 is located on the front side of the second suction port 102 along the X direction, the water sprayed by the water spray assembly 130 will wet the ground in the area directly below and adjacent to the front side of the second suction port 102. During the process of the second suction port 102 sucking up the cleaning water on the ground, the water flow will carry away dust and stains as it passes over the surface to be cleaned. The cleaning effect is achieved by the impact and rinsing of the water flow, thus eliminating the need for a roller brush. The squeegee assembly 120 is located on the rear side of the second suction port 102 along the X direction on the floor brush device 100. As the floor brush device 100 moves, the squeegee assembly 120 can scrape away water stains on the ground, ensuring that all wastewater can be sucked away by the second suction port 102, avoiding water stains remaining on the ground.
[0071] It should be noted that in the floor brush device 100 provided in this application embodiment, the first suction port 101 and the second suction port 102 are distributed one in front of the other along the cleaning direction and are separated by the separator 150. During the cleaning process, large-volume debris particles are blocked by the separator 150 and are sucked in by the first suction port 101. The remaining small-volume dust particles pass under the separator 150 and are sucked in by the second suction port 102, thus achieving the diversion of large and small particles of debris. The second suction port 102 will not be blocked by large-volume debris, and small-volume particles of debris and water stains will not remain on the ground, thereby improving cleaning efficiency.
[0072] Compared to existing technologies, the floor brush device 100 in this embodiment does not require a roller brush. As cleaning water passes through the surface to be cleaned and is drawn into the second suction port 102, it carries away dust and stains, achieving a good cleaning effect. In this way, no wastewater remains on the floor brush device 100, preventing odors from developing when the device is left idle after cleaning. Furthermore, there is no need to clean the roller brush after cleaning, saving time and effort, and eliminating the need for a separate drying device, thus reducing product costs.
[0073] Please continue to refer to Figures 1 to 4 In some embodiments, the water spray assembly 130 is connected to the separator 150. The gap between the outer wall of the water spray assembly 130 on the side opposite to the separator 150 and the wiper assembly 120 forms a second suction port 102 to improve the compactness of the front-to-back arrangement of the first suction port 101 and the second suction port 102. The first suction port 101 and the second suction port 102 can be positioned as close as possible to the separator 150.
[0074] It is understandable that the first suction port 101 is on the front side of the separator 150, while the second suction port 102 is on the rear side of the separator 150 and can be close to the separator 150. The water spraying assembly 130 sprays water between the second suction port 102 and the separator 150 to ensure that the second suction port 102 has a sufficiently large suction force on the area wetted by the water spraying assembly 130, thereby improving the sewage suction efficiency.
[0075] Furthermore, as the floor brush device 100 moves forward, residual small particles and dirt on the ground that were not sucked in by the first suction port 101 will immediately enter the water spray coverage area of the spray assembly and the effective suction coverage area of the second suction port 102 after passing under the separator 150, thus being quickly cleaned up, improving cleaning efficiency and cleaning effect.
[0076] The specific structure of the wiper assembly 120 and the specific formation of the second suction port 102 will be described in detail below.
[0077] Figure 5 This is a schematic diagram of the squeegee assembly in the floor brush device provided in the embodiments of this application; Figure 6 This is a schematic diagram of the water spray cover in the floor brush device provided in the embodiment of this application.
[0078] Please refer to Figures 1 to 6 In one possible implementation, the wiper assembly 120 may include a wiper blade 122 and a wiping element 121. A suction channel 104 is formed between the wiper blade 122 and the outer wall of the spray assembly 130, and the suction channel 104 is connected to the floor brush duct 111. The wiping element 121 is connected to the wiper blade 122, and there is a gap between the wiping element 121 and the outer wall of the spray assembly 130 to form a second suction port 102, which is connected to the suction channel 104.
[0079] Understandably, the sidewall of the water spray assembly 130 facing the wiper assembly 120 is mated with the wiper blade 122, forming a suction channel 104 between them. The suction channel 104 connects the second suction port 102 and the floor brush duct 111. Wastewater and particles sucked in from the second suction port 102 will enter the floor brush duct 111 through the suction channel 104.
[0080] For example, the squeegee 121 can be connected to the lower edge of the wiper blade 122, and a second suction port 102 is formed through the gap between the squeegee 121 and the water spray assembly 130, so that the second suction port 102 has a flat structure, thereby increasing the negative pressure suction force that the second suction port 102 can generate.
[0081] The width direction of the floor brush device 100 is defined as the Y direction, which is perpendicular to the X direction. The squeegee 121 can extend along the Y direction at the lower edge of the squeegee 122, thereby making the second suction port 102 have a flat and slender structure along the Y direction. This effectively increases the suction power of the second suction port 102, allowing the cleaning water sprayed onto the ground by the water spray assembly 130 to flow more quickly and wash away stains more efficiently, thus achieving a better cleaning effect on the stains on the ground.
[0082] For example, the squeegee 121 can be made of elastic materials such as soft rubber, rubber, or silicone. The squeegee 121 can be a squeegee strip with a strip-shaped structure. The length of the first squeegee 121 can be equal to or similar to the length of the wiper blade 122 along the Y direction. The squeegee 121 and the wiper blade 122 can be bonded together with adhesive, or they can be fixedly connected by fasteners such as clips, or they can be integrally molded by overmolding. This application does not specifically limit the specific methods used in this embodiment.
[0083] It should be noted that the lower edges of the scraping component 121 and the water spraying component 130 can be arranged parallel to each other, and their lengths can be equal or similar, so as to ensure that the length of the second suction port 102 formed by the two is as close as possible to the width of the floor brush device 100.
[0084] In some embodiments, the wiping member 121 is inclined forward in a first direction relative to the vertical direction, and the water spray assembly 130 is inclined forward in a first direction on the sidewall of the wiping assembly 120.
[0085] It is understandable that when the lower edge of the scraper 121 contacts the surface to be cleaned, the lower edge of the water spray assembly 130 has a gap with the surface to be cleaned, so that the second suction port 102 can be tilted towards the front side of the cleaning direction of the floor brush device 100. The second suction port 102 can suck up sewage in the direction of the floor brush device 100, and has a higher sewage suction efficiency.
[0086] For example, the tilt angle of the scraper 121 relative to the vertical direction is 5°, 10°, 30°, 45°, 60°, 80°, 85°, etc., and this application embodiment does not specifically limit this. In addition, the scraper 121 can have a certain interference fit when it contacts the surface to be cleaned, that is, the scraper 121 abuts against the surface to be cleaned and produces a certain degree of elastic deformation.
[0087] In some embodiments, the lower edge of the separator 150 extends along the width direction of the device body 110. In the vertical direction, the lower edge of the scraper 121 is lower than the lower edge of the separator 150, so that when the scraper 121 contacts the surface to be cleaned, there is a gap between the lower edge of the separator 150 and the surface to be cleaned.
[0088] Understandably, during the cleaning process of the floor brush device 100, there is a gap between the lower edge of the partition 150 and the floor, which allows dust and small particles on the floor to pass through from under the partition 150 and be sucked in by the second suction port 102.
[0089] For example, the height difference between the lower edge of the scraper 121 and the lower edge of the separator 150 is less than the gap between the scraper 121 and the outer wall of the water spray assembly 130. This ensures that the particles passing under the separator 150 are less than the height of the second suction port 102, thus ensuring the unobstructed flow of the second suction port 102 and preventing it from being blocked.
[0090] In one possible implementation, the water spray assembly 130 has a protrusion 123 on the side facing the scraper 121. The protrusion 123 abuts against the scraper 121 inside the second suction port 102, thereby preventing the gap between the scraper 121 and the water spray assembly 130 from closing under the action of negative pressure suction, so as to ensure the smooth intake of airflow from the second suction port 102.
[0091] Understandably, because the air pressure inside the second suction port 102 is lower than the atmospheric pressure of the external environment, the outer walls of the scraper 121 and the water spray assembly 130 tend to move closer together due to the pressure difference. The protrusion 123 can keep the second suction port 102 in an open state.
[0092] For example, the protrusion 123 may be integrally formed with the housing structure of the water spray assembly 130, and the protrusion 123 protrudes toward the scraper 121 on the outer surface of the water spray assembly 130.
[0093] For example, the second suction port 102 extends along the width direction of the device body 110. There are multiple protrusions 123, which are arranged at intervals along the extension direction of the second suction port 102, so as to provide support for each position in the length direction of the second suction port 102 and ensure smooth airflow.
[0094] In some embodiments, the width of the protrusion 123 at the outer end of the second suction port 102 is greater than the width of the protrusion 123 at the inner end of the second suction port 102, thereby reducing the loss of airflow during the process of flowing into the first suction port 101.
[0095] It is understandable that the side wall of the protrusion 123 facing the outside of the second suction port 102 is arc-shaped, which can guide the airflow drawn into the second suction port 102 and improve the smoothness of the airflow.
[0096] For example, the protrusion 123 may be teardrop-shaped.
[0097] It should be noted that the number of protrusions 123 can be two, three, four or more. This application embodiment does not limit the number of protrusions 123 or the specific spacing between adjacent protrusions 123.
[0098] In some embodiments, the wiper assembly 120 has an air outlet 124 at one end away from the second suction port 102. The air outlet 124 connects the second suction port 102 and the floor brush duct 111. A flow guide structure 103 is provided between the wiper assembly 120 and the water spray assembly 130. The flow guide structure 103 is opposite to the air outlet 124.
[0099] Understandably, when the airflow entering between the wiper assembly 120 and the spray assembly 130 converges at the air outlet 124, the airflow guide structure 103 guides the airflow to avoid turbulent airflow and reduce airflow loss.
[0100] For example, the air outlet 124 can be located in the middle of the length direction of the wiper assembly 120. When the second suction port 102 sucks in airflow and sewage, as the airflow and sewage enter between the wiper blade 122 and the water spray assembly 130, the airflow and sewage will converge towards the middle air outlet 124. The airflow and sewage that converge on both sides of the air outlet 124 can enter the air outlet 124 under the guidance of the guide structure 103.
[0101] In some embodiments, the flow guiding structure 103 may include a first flow guiding portion 1031 and a second flow guiding portion 1032. The first flow guiding portion 1031 is connected to the wiper assembly 120, and the second flow guiding portion 1032 is connected to the outer wall of the water spray assembly 130. The first flow guiding portion 1031 and the second flow guiding portion 1032 are opposite to and abut against each other. In this way, the flow guiding structure 103 can be formed together when the wiper assembly 120 and the water spray assembly 130 are assembled, ensuring that the lower and upper ends of the flow guiding structure 103 can be supported between the wiper assembly 120 and the water spray assembly 130.
[0102] For example, the first guide portion 1031 and the second guide portion are matched in shape, and both can be teardrop-shaped. When the water spray assembly 130 and the wiper blade 122 are connected, the first guide portion 1031 and the second guide portion 1032 can be directly opposite each other.
[0103] For example, the first guide portion 1031 can be integrally formed with the wiper blade 122. The second guide portion 1032 can be integrally formed with the outer side wall of the water spray assembly 130.
[0104] The specific structure of the water spray assembly 130 will be described in detail below.
[0105] Please continue to refer to Figures 1 to 6 In one possible implementation, the water spray assembly 130 may include a water spray body 131 and a water spray cover 132. The water spray body 131 is connected to the separator 150, and the water spray cover 132 is connected to the side of the water spray body 131 facing the wiper assembly 120. The water spray cover 132 and the water spray body 131 enclose a water spray cavity 133. The water spray cover 132 is provided with water spray holes 134 communicating with the water spray cavity 133. The water spray holes 134 spray water downwards towards the device body 110, thereby improving the wetting efficiency of the area facing the ground as described by the second suction port 102.
[0106] It is understood that the water spray hole 134 is located at the lower edge of the water spray cover 132, and the water spray hole 134 is located on the front side of the second suction port 102 along the first direction. In this way, the cleaning water sprayed from the water spray hole 134 can impact the ground, remove stubborn stains, and allow the water flow to play a good and efficient cleaning role on the ground during the process of the second suction port 102 sucking in the cleaning water.
[0107] For example, there are multiple water spray holes 134, which are arranged at intervals along the width direction of the device body 110, so that water can be supplied evenly at various positions in the width direction of the device body 110.
[0108] For example, the spray cover 132 can be mated with the wiper blade 122. The spray body 131 can be connected to the separator 150 by bolt fasteners. Alternatively, the spray body 131 can be welded to the separator 150.
[0109] In some embodiments, the floor brush duct 111 has an air inlet 111a and an air outlet 111b, with the air inlet 111a forming a first suction port 101. The floor brush device 100 also includes a suction pipe 140, which is connected to the air outlet 111b. A second suction port 102 is connected between the air inlet 111a and the air outlet 111b.
[0110] It is understandable that the debris and sewage sucked in by the first suction port 101 and the second suction port 102 can converge in the floor brush duct 111 and enter the sewage suction pipe 140 together, so that the garbage, debris and water stains sucked in by the first suction port 101 and the second suction port 102 can be concentrated and collected in the storage space.
[0111] In some embodiments, the device body 110 may include a duct housing 112, which forms a floor brush duct 111.
[0112] For example, at least a portion of the sidewall of the duct housing 112 along the rear side in the first direction forms a partition 150, thereby ensuring the compactness of the floor brush device 100 structure and improving space utilization.
[0113] For example, the separator 150 is connected to the rear side wall of the duct housing 112 along the first direction. This makes the water spray assembly 130 connected to the separator 150 as close as possible to the duct housing 112, improving the compactness of the floor brush device 100 structure.
[0114] Please refer to Figures 1 to 6 This application provides a cleaning device 10, which includes a device body 200 and a floor brush device 100 as described above. The floor brush device 100 is movably connected to the device body 200. When performing cleaning operations, the user can move the floor brush device 100 by pushing or pulling the device body 200.
[0115] It is understandable that a suction channel 104 can be connected between the floor brush device 100 and the main body 200, and a sewage tank can be installed on the main body 200. Sewage sucked in by the floor brush device 100 can enter the sewage tank through the suction channel 104.
[0116] In addition, a fan unit can be installed on the main body 200 of the equipment. The fan unit is used to generate negative pressure airflow, thereby causing the first suction port 101 and the second suction port 102 to generate negative pressure suction. The clean airflow after being filtered by the sewage tank passes through the fan unit and is discharged to the outside of the main body 200 of the equipment.
[0117] This application provides a floor brush device and cleaning equipment. The floor brush device includes a main body, a squeegee assembly, and a spray assembly. The floor brush device has a floor brush air duct, a first suction port, and a second suction port. Both the first and second suction ports face downwards from the main body and are connected to the floor brush air duct. A partition 150 is provided at the bottom of the main body. The first suction port is located on the front side of the partition 150 along a first direction, and the second suction port is located on the rear side of the partition 150 along the first direction. The squeegee assembly is disposed on the rear side of the second suction port along the first direction. The spray assembly is disposed between the partition 150 and the second suction port, and is configured to spray water towards the area facing the second suction port. The first direction is the cleaning direction of the floor brush device, thereby achieving the separation of particles of varying sizes and achieving a good cleaning effect. This method eliminates the need for a roller brush, prevents wastewater residue on the floor brush device, and avoids the generation of odors when the floor brush device is placed after cleaning.
[0118] Finally, it should be noted that 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 or all of the technical features therein.
