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 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 after cleaning, which makes the floor brush prone to producing odors.
[0006] In a first aspect, this application provides a floor brush device, which includes a device body, a squeegee assembly, a water-blocking assembly, and a water-spraying assembly; the device body has a floor brush air duct; the squeegee assembly, the water-blocking assembly, and the water-spraying assembly are all disposed in the device body.
[0007] The water-blocking component is located in front of the squeegee component along the cleaning direction of the floor brush device; a first suction port is formed between the squeegee component and the water-blocking component, facing downwards from the main body of the device; the water spraying component is connected to the side of the water-blocking component away from the squeegee component, and together with the water-blocking component, a water spraying chamber is formed, the water spraying chamber is adjacent to the first suction port, and the water spraying component is configured to spray water into the water spraying chamber; the water spraying chamber has a water outlet facing downwards from the main body of the device.
[0008] The floor brush device provided in this application forms a water spray chamber in front of the first suction port. Water is sprayed into the water spray chamber using a water spray component. The water in the water spray chamber can flow from the water outlet to the surface to be cleaned. In this way, the water-blocking component isolates the water spray chamber from the first suction port. The negative pressure suction generated by the first suction port can draw the cleaning water dripping onto the surface to be cleaned from front to back through the water-blocking component and into the interior. During this process, the cleaning water will carry away dust and stains as it passes over the surface to be cleaned, achieving a good cleaning effect. In this way, the roller brush is eliminated, and there will be no wastewater residue on the floor brush device, avoiding the generation of odors when the floor brush device is placed after cleaning.
[0009] As an optional implementation, the wall of the water spray chamber is provided with an air inlet, which connects the inner and outer sides of the water spray chamber.
[0010] With this configuration, since the water spray chamber is spatially connected to the first suction port, the negative pressure generated by the first suction port can cause airflow to flow into the air inlet, and use the airflow to accelerate the water flow in the water spray chamber to the surface to be cleaned.
[0011] As an optional implementation, the air inlet is located at the top of the water spray chamber.
[0012] With this configuration, the air intake direction of the air inlet can be aligned with the water flow direction inside the spray chamber, improving the efficiency of the water flow downwards.
[0013] As an optional implementation, there can be multiple air inlets, which are arranged at intervals along the length of the water spray chamber.
[0014] This design allows for accelerated water droplets to fall at various locations along the width of the spray chamber, ensuring uniform water droplet distribution across different locations along the width of the cleaning device.
[0015] As an optional implementation, the wiper assembly may include a wiper blade and a first wiping element, the first wiping element being connected to the lower edge of the wiper blade; a second wiping element is connected to the lower edge of the water spray assembly, the second wiping element being located in front of the first wiping element along the cleaning direction of the floor brush device; a cleaning cavity is formed between the first wiping element and the second wiping element, and the water outlet is connected to the cleaning cavity.
[0016] This design allows for greater negative pressure suction through the first suction port, ensuring that wastewater on the ground can be drawn in, preventing water stains from remaining or overflowing.
[0017] As an optional implementation, the water-proof assembly may include a water-proof plate and a flexible member, the flexible member being connected to the lower edge of the water-proof plate and located between the first scraper and the second scraper; a first suction port is formed between the flexible member and the first scraper, and a water outlet is formed between the flexible member and the second scraper.
[0018] This design isolates the first suction port and the water outlet, preventing water dripping from the outlet from being directly sucked into the first suction port and thus failing to clean the surface to be cleaned.
[0019] As an optional implementation, the lower edge of the flexible member is higher than the lower edges of the first and second scraping members; when the first and second scraping members are in contact with the surface to be cleaned, the lower edge of the flexible member is spaced from the surface to be cleaned, so that water entering the cleaning chamber passes through the lower edge of the flexible member and is sucked into the first suction port.
[0020] With this design, the cleaning water can flow along the surface to be cleaned and make full contact as it passes through the lower edge of the flexible component, thus improving the cleaning effect.
[0021] As an optional implementation, the first scraper and the flexible member have a first side air inlet between their two ends along the width direction of the floor brush device, and the first side air inlet communicates with the cleaning chamber; and / or, the second scraper and the flexible member have a second side air inlet between their two ends along the width direction of the floor brush device, and the second side air inlet communicates with the cleaning chamber.
[0022] This design allows air to enter from both sides of the cleaning chamber, causing wastewater from the surface to be cleaned to converge towards the center and be more easily drawn into the brush duct from the first suction port.
[0023] As an optional implementation, the water spray assembly may include a water spray housing and a water spray cover plate. The water spray housing is connected to the water-blocking assembly. The water spray cover plate is connected to the side of the water spray housing away from the water-blocking assembly and forms a water spray channel. The side of the water spray housing facing the water-blocking assembly is provided with water spray holes, which are connected to the water spray channel.
[0024] This design ensures that the water in the spray chamber flows and drips along the surface of the water-proof component, preventing water from splashing or overflowing.
[0025] As an optional implementation, there are multiple water spray holes, which are arranged at intervals along the length of the water spray chamber.
[0026] This configuration ensures uniform water supply across all locations along the width of the device.
[0027] As an optional implementation, the edge of the water spray housing is provided with a water baffle plate, which extends toward the water-proof assembly. The water-proof assembly has a sealing groove on the side facing the water spray assembly, and the end of the water baffle plate is inserted into the sealing groove.
[0028] This design allows the water baffle to create a space for water spraying while ensuring the water spray chamber has good sealing properties.
[0029] As an optional implementation, the floor brush device has a second suction port that is connected to the floor brush air duct and is located in front of the first suction port along the cleaning direction of the floor brush device.
[0030] This setup allows for the first intake of large volumes of debris and contaminants into the floor brush duct via the second suction port, followed by wetting the surface to be cleaned to remove any remaining stubborn dust and stains, thus improving cleaning effectiveness.
[0031] 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.
[0032] This application provides a floor brush device and cleaning equipment. The floor brush device includes a main body, a squeegee assembly, a water-isolating assembly, and a water spraying assembly. The main body has a floor brush air duct. The squeegee assembly, water-isolating assembly, and water spraying assembly are all disposed on the main body. The water-isolating assembly is located on the front side of the squeegee assembly along the cleaning direction of the floor brush device. A first suction port facing downwards from the main body is formed between the squeegee assembly and the water-isolating assembly. The water spraying assembly is connected to the side of the water-isolating assembly away from the squeegee assembly and forms a water spraying chamber with the water-isolating assembly. The water spraying chamber is disposed adjacent to the first suction port. The water spraying assembly is configured to spray water into the water spraying chamber. The water spraying chamber has a water outlet facing downwards from the main body. In this way, the water-isolating assembly isolates the water spraying chamber from the first suction port. The negative pressure suction generated by the first suction port can draw the cleaning water dripping onto the surface to be cleaned from front to back through the water-isolating assembly and into the interior. During this process, the cleaning water will carry away dust and stains as it passes over the surface to be cleaned, achieving a good cleaning effect. There will be no wastewater residue on the floor brush device, avoiding the generation of odors when the floor brush device is placed after cleaning.

[0047] 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. For example, they can refer to a fixed connection, an indirect connection through an intermediate medium, or the internal communication between two components or the interaction between two components. Those skilled in the art can understand the specific meaning of the above terms in this application according to the specific circumstances.
[0048] In the description of this application, it should be understood that the terms "upper", "lower", "front", "back", "vertical", "horizontal", "top", "bottom", "inner", "outer", etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are only for the convenience of describing this application and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this application.
[0049] 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.
[0050] 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.
[0051] 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.
[0052] 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 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.
[0053] 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.
[0054] 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, through the design of the water spray path of the water spray component, uses a water-separating component to isolate the water spray chamber and the first suction port. This allows the water sprayed from the water spray component to drip onto the front of the first suction port. Relying on the suction force of the first suction port, the dripping cleaning water carries away dust and stains during the process of being sucked into the first port, improving cleaning efficiency. Furthermore, after cleaning, there is no need for drying, and no odor is generated.
[0055] The following section provides examples illustrating the application scenarios of the floor brush device and cleaning equipment provided in the embodiments of this application.
[0056] 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.
[0057] 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 view of position A in the middle.
[0058] See Figures 1 to 3 As shown, this application provides a floor brush device 100, which includes a device body 110, a squeegee assembly 120, a water-blocking assembly 130, and a water-spraying assembly 140. The squeegee assembly 120, the water-blocking assembly 130, and the water-spraying assembly 140 are all disposed on the device body 110. The device body 110 can move along the surface to be cleaned, the water-spraying assembly 140 can wet the surface to be cleaned, the water-blocking assembly 130 is used to isolate the squeegee assembly 120 and the water-spraying assembly 140, and the squeegee assembly 120 can scrape away water stains from the wetted surface.
[0059] The water-blocking component 130 is located on the front side of the wiper component 120 along the cleaning direction of the floor brush device 100. A first suction port 102 is formed between the wiper component 120 and the water-blocking component 130, facing downwards from the device body 110. The device body 110 has a floor brush air duct 111, and the first suction port 102 is connected to the floor brush air duct 111.
[0060] It is understandable that the first suction port 102 faces the surface to be cleaned below the main body 110 of the device, and the negative pressure suction generated by the first suction port 102 can suck in the sewage generated during the cleaning process.
[0061] In some embodiments, the water spray assembly 140 is connected to the side of the water-blocking assembly 130 opposite to the wiper assembly 120, and together with the water-blocking assembly 130, forms a water spray cavity 142. The water spray cavity 142 is disposed adjacent to the first suction port 102, and the water spray assembly 140 is configured to spray water into the water spray cavity 142. The water spray cavity 142 has a water outlet 1421 facing downwards from the device body 110.
[0062] It is understandable that the cleaning water sprayed into the spray chamber 142 can flow from the outlet 1421 to the surface to be cleaned. Since the outlet 1421 is located close to the first suction port 102, the negative pressure suction generated by the first suction port 102 will suck the sewage on the surface to be cleaned into the floor brush duct 111.
[0063] It should be noted that in the floor brush device 100 provided in this application embodiment, a water spraying chamber 142 is formed on the front side of the first suction port 102. Water is sprayed into the water spraying chamber 142 by the water spraying assembly 140. The water in the water spraying chamber 142 can flow from the water outlet 1421 to the surface to be cleaned. In this way, the water-blocking assembly 130 isolates the water spraying chamber 142 and the first suction port 102. The negative pressure suction generated by the first suction port 102 can draw the cleaning water dripping onto the surface to be cleaned from front to back through the water-blocking assembly 130 and into the interior.
[0064] Compared to existing technologies, the floor brush device 100 in this embodiment does not require the use of a roller brush. As the cleaning water passes through the surface to be cleaned and is sucked into the first suction port 102, it carries away dust and stains, achieving a good cleaning effect. In this way, there will be no wastewater residue on the floor brush device 100, avoiding the generation of odors when the floor brush device 100 is placed after cleaning.
[0065] Figure 4 This is a schematic diagram of the squeegee assembly in the floor brush device provided in the embodiments of this application; Figure 5 This is a schematic diagram of the water-proof component in the floor brush device provided in the embodiments of this application; Figure 6 This is a schematic diagram of the water spray component in the floor brush device provided in the embodiments of this application; Figure 7 A schematic diagram showing the connection of the squeegee assembly, water-blocking assembly, and water-spraying assembly of the floor brush device provided in an embodiment of this application; Figure 8 for Figure 7 A partial view of position B in the middle.
[0066] The water supply path of the water spray assembly 140 is described in detail below.
[0067] Please refer to Figures 1 to 8 In one possible implementation, the cavity wall of the water spray chamber 142 is provided with an air inlet 1422, which connects the inner and outer sides of the water spray chamber 142.
[0068] It is understandable that, since the water spray chamber 142 is spatially connected to the first suction port 102, the negative pressure generated by the first suction port 102 can cause the air inlet 1422 to flow into the airflow, and the airflow can flow out from the water outlet 1421. In this process, the airflow can be used to drive the water in the water spray chamber 142 to the surface to be cleaned.
[0069] In some embodiments, the air inlet 1422 is located at the top of the water spray chamber 142. When water in the water spray chamber 142 drips down onto the surface to be cleaned by gravity, the air inlet 1422 can be aligned with the water flow direction in the water spray chamber 142, thereby improving the efficiency of the water flow downwards.
[0070] For example, there can be multiple air inlets 1422, which are arranged at intervals along the length of the water spray chamber 142. This allows the water to drip at various positions in the width direction of the water spray chamber 142, ensuring the uniformity of water dripping at different positions in the width direction of the cleaning device.
[0071] It should be noted that the number of air inlets 1422 can be two, three, four, or more. The shape of the air inlets 1422 can be square, circular, or other regular or irregular shapes, and this application embodiment does not specifically limit this.
[0072] In some embodiments, the wiper assembly 120 may include a wiper blade 122 and a first wiping member 121, the first wiping member 121 being connected to the lower edge of the wiper blade 122. A second wiping member 141 is connected to the lower edge of the water spray assembly 140, and the second wiping member 141 is located in front of the first wiping member 121 along the cleaning direction of the floor brush device 100. A cleaning cavity 104 is formed between the first wiping member 121 and the second wiping member 141, and a water outlet 1421 communicates with the cleaning cavity 104.
[0073] It is understandable that the second scraper 141 is located in front of the first scraper 121 along the cleaning direction of the floor brush device 100, the cleaning chamber 104 is the area between the first scraper 121 and the second scraper 141, and the first suction port 102 is connected to the cleaning chamber 104. The first suction port 102 can generate a greater negative pressure suction force to ensure that the sewage on the ground can be sucked into it, and to avoid water stains remaining or overflowing.
[0074] In some embodiments, one end of the waterproofing component 130 facing downwards from the device body 110 is located between the first scraper 121 and the second scraper 141. The end of the waterproofing component 130 facing downwards from the device body 110 is higher than the lower edges of the first scraper 121 and the second scraper 141.
[0075] It is understandable that when the lower edge of the first scraping member 121 contacts the surface to be cleaned, the lower edge of the flexible member 131 has a gap with the surface to be cleaned. Water sprayed onto the surface to be cleaned can pass through the lower edge of the water-proof component 130 and enter the interior of the first suction port 102, ensuring that the cleaning water passes through the surface to be cleaned during the process of being sucked into the first suction port 102, thus achieving a good cleaning effect.
[0076] For example, the lower edges of the first scraper 121 and the second scraper 141 are flush. During the cleaning process, it can be ensured that the first scraper 121 and the second scraper 141 are in contact with the surface to be cleaned at the same time, ensuring that the cleaning cavity 104 is relatively sealed in the cleaning direction, and the first suction port 102 can form a large negative pressure suction force.
[0077] In one possible implementation, the water-blocking assembly 130 may include a water-blocking plate 132 and a flexible member 131. The flexible member 131 is connected to the lower edge of the water-blocking plate 132 and is located between the first scraper member 121 and the second scraper member 141. A first suction port 102 is formed between the flexible member 131 and the first scraper member 121, and a water outlet 1421 is formed between the flexible member 131 and the second scraper member 141.
[0078] Understandably, the first suction port 102 and the water outlet 1421 are isolated from each other. The lower edge of the water-blocking component 130 can block the water flow, ensuring that the water flowing out of the water outlet 1421 can drip onto the surface to be cleaned, and preventing the water dripping from the water outlet 1421 from being directly sucked into the first suction port 102 and thus failing to clean the surface to be cleaned.
[0079] For example, the lower edge of the flexible member 131 is higher than the lower edges of the first scraper member 121 and the second scraper member 141; when the first scraper member 121 and the second scraper member 141 contact the surface to be cleaned, there is a gap between the lower edge of the flexible member 131 and the surface to be cleaned, so that water entering the cleaning chamber 104 passes through the lower edge of the flexible member 131 and is sucked into the first suction port 102. The cleaning water can flow along the surface to be cleaned and make full contact as it passes through the lower edge of the flexible member 131, thereby improving the cleaning effect.
[0080] The direction of movement of the floor brush device 100 during cleaning is defined as the X direction, and the width direction of the floor brush device 100 is defined as the Y direction, which is perpendicular to the X direction.
[0081] Please refer to Figures 1 to 8 As an optional implementation, the first scraper 121 and the second scraper 141 both extend along the width direction of the device body 110, and the dimensions of the first scraper 121 and the second scraper 141 are matched along the width direction of the device body 110, so that the cleaning cavity 104 can have the largest possible cleaning coverage area in the width direction of the device body 110.
[0082] It is understood that both the first scraper 121 and the second scraper 141 extend along the Y direction. The first scraper 121 and the second scraper 141 can be arranged in parallel to ensure uniform negative pressure suction in all areas of the cleaning chamber 104 along the Y direction.
[0083] In some embodiments, the first scraper 121 is inclined toward the front of the device body 110 relative to the vertical direction, which can make the first suction port 102 face the forward direction when the cleaning device is cleaning, thereby improving the suction efficiency of sewage on the surface to be cleaned.
[0084] In some embodiments, the second scraper 141 is arranged vertically. During the cleaning process of the floor brush device 100, the second scraper 141 is kept in close contact with the surface to be cleaned, so that the cleaning chamber 104 can have a continuous and stable negative pressure through the first suction port 102. The cleaning water dripping onto the surface to be cleaned can be sucked into the first suction port 102 to achieve the effect of cleaning the floor with water.
[0085] For example, the length of the first wiping member 121 can be equal to or similar to the length of the wiper blade 122. The first wiping member 121 and the wiper blade 122 can be bonded together with adhesive, or the first wiping member 121 and the wiper blade 122 can be fixedly connected by fasteners such as clips, or the first wiping member 121 and the wiper blade 122 can be integrally formed by overmolding. This application embodiment does not specifically limit this.
[0086] For example, the length of the second scraper 141 can be equal to or similar to the length of the water spray assembly 140. The lower edge of the second scraper 141 and the water spray assembly 140 can be bonded together with adhesive, or the lower edge of the second scraper 141 and the water spray assembly 140 can be fixedly connected by fasteners such as clips, or the outer shell of the second scraper 141 and the water spray assembly 140 can be integrally formed by overmolding. This application embodiment does not specifically limit this.
[0087] For example, the flexible component 131 can be made of elastic materials such as rubber or silicone. The flexible component 131 can be a strip structure, and its length can be equal to or similar to the length of the water-blocking plate 132. The flexible component 131 and the water-blocking plate 132 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 embodiment does not specifically limit the specific methods used.
[0088] In some embodiments, at least one of the first scraping member 121 and the flexible member 131 has a protrusion 123 on the side facing the other. When the first suction port 102 generates negative pressure suction, the protrusion 123 abuts against the flexible member 131 and the first scraping member 121 to maintain the gap 101 and prevent the first scraping member 121 and the flexible member 131 from closing the first suction port 102 under the action of negative pressure suction, thereby ensuring smooth airflow.
[0089] Understandably, because the air pressure inside the first suction port 102 is lower than the external annular atmospheric pressure, the first scraping member 121 and the flexible member 131 will tend to move closer to each other under the influence of the internal and external pressure difference. The protrusion 123 can keep the first suction port 102 in an open state.
[0090] For example, the protrusion 123 may be integrally formed with the first scraper 121, and the protrusion 123 protrudes from the surface of the first scraper 121 toward the flexible member 131.
[0091] In some embodiments, the width of the protrusion 123 at the outer end of the first suction port 102 is greater than the width of the protrusion 123 at the inner end of the first suction port 102, thereby reducing the loss of airflow during the process of flowing into the first suction port 102.
[0092] It is understandable that the sidewall of the protrusion 123 facing the outside of the first suction port 102 is arc-shaped, which can guide the airflow drawn into the first suction port 102 and improve the smoothness of the airflow.
[0093] For example, the protrusion 123 may be teardrop-shaped.
[0094] In some embodiments, the wiper assembly 120 has an air outlet 124 at one end away from the first suction port 102. The air outlet 124 connects the gap 101 and the floor brush duct 111. A guide structure 103 is provided in the gap 101, and the guide structure 103 is opposite to the air outlet 124.
[0095] It is understandable that when the airflow entering the gap 101 recirculates at the air outlet 124, the guide structure 103 can guide the airflow to avoid turbulent airflow and reduce airflow loss.
[0096] For example, the air outlet 124 can be located in the middle of the length direction of the wiper assembly 120. When the first suction port 102 sucks in airflow and sewage, as the airflow and sewage enter between the wiper blade 122 and the baffle plate 132, 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.
[0097] 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 water-blocking 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-blocking assembly 130 are assembled, ensuring that the lower and upper ends of the flow guiding structure 103 can be supported at the bottom and top of the gap 101.
[0098] For example, the first guide portion 1031 and the second guide portion are matched in shape, and both can be teardrop-shaped. When the baffle plate 132 and the scraper plate 122 are connected, the first guide portion 1031 and the second guide portion can be directly opposite each other.
[0099] 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 baffle plate 132.
[0100] In some embodiments, the first scraper 121 and the flexible member 131 have a first side air inlet 1041 between their two ends along the width direction of the floor brush device 100. The first side air inlet 1041 is connected to the cleaning chamber 104, so that air can also enter from both sides of the cleaning chamber 104, so that the sewage on the surface to be cleaned gathers in the middle and is more easily sucked into the floor brush air duct 111 from the first suction port 102.
[0101] In some embodiments, the second scraper 141 and the flexible member 131 have a second side air inlet 1042 between their two ends along the width direction of the floor brush device 100. The second side air inlet 1042 is connected to the cleaning chamber 104, so that air can also enter from both sides of the cleaning chamber 104, so that the sewage on the surface to be cleaned gathers in the middle and is more easily sucked into the floor brush air duct 111 from the first suction port 102.
[0102] The specific structure of the water spray assembly 140 is described in detail below.
[0103] Please refer to Figures 1 to 8 As an optional implementation, the water spray assembly 140 may include a water spray housing 143 and a water spray cover 144, with the water spray housing 143 connected to the water-blocking assembly 130. The water spray cover 144 is connected to the side of the water spray housing 143 facing away from the water-blocking assembly 130 and forms a water spray channel 146. The side of the water spray housing 143 facing the water-blocking assembly 130 has water spray holes 145, which communicate with the water spray channel 146, thereby ensuring that the water in the water spray chamber 142 flows and drips along the surface of the water-blocking assembly 130, preventing water splashing or overflow.
[0104] For example, there are multiple water spray holes 145, which are arranged at intervals along the length of the water spray cavity 142, so that water can be supplied evenly at various positions in the width direction of the device body 110.
[0105] For example, the water-proof component 130 has a guide surface 133 facing the water spray component 140, which is configured to spray water onto the guide surface 133, which directs the cleaning water and drips it onto the surface to be cleaned.
[0106] In some embodiments, the edge of the water spray housing 143 is provided with a baffle plate 1431, which extends toward the water-blocking assembly 130. The water-blocking assembly 130 is provided with a sealing groove 134 on the side facing the water spray assembly 140. The end of the baffle plate 1431 is inserted into the sealing groove 134, so that the baffle plate 1431 can be used to form a water spraying space and ensure that the water spraying chamber 142 has good sealing performance.
[0107] In one possible implementation, the floor brush device 100 has a second suction port 105, which is connected to the floor brush air duct 111 and is located in front of the first suction port 102 along the cleaning direction of the floor brush device 100.
[0108] Understandably, as the floor brush device 100 moves forward, large volumes of garbage and debris can first be sucked into the floor brush air duct 111 through the second suction port 105, and then the remaining stubborn dust and stains can be sucked in and cleaned through the first suction port 102 by wetting the surface to be cleaned, thereby improving the cleaning effect.
[0109] For example, the floor brush device 100 has an air duct housing, which forms the floor brush air duct 111. The second suction port 105 can be located at the front end of the air duct housing. The wiper assembly 120 can be connected to the rear end of the air duct housing, and the air outlet 124 on the wiper assembly 120 is connected to the rear end of the air duct housing. Thus, the airflow and debris sucked in from the second suction port 105, as well as the airflow and wastewater sucked in from the first suction port 102, will be collected together in the thickness of the air duct housing and enter the dirt collection chamber of the cleaning device 10.
[0110] It should be noted that the second suction port 105 and the first suction port 102 have a certain distance between them, and the second scraping member 141 is positioned between the first suction port 102 and the second suction port 105.
[0111] This application provides a cleaning device 10, which includes a main body 200 and a floor brush device 100 as described above. The floor brush device 100 is movably connected to the main body 200. When performing cleaning operations, the user can move the floor brush device 100 by pushing or pulling the main body 200.
[0112] It is understandable that a suction pipe 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 pipe.
[0113] 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 102 and the second suction port 105 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.
[0114] This application provides a floor brush device and cleaning equipment. The floor brush device includes a main body, a squeegee assembly, a water-isolating assembly, and a water spraying assembly. The main body has a floor brush air duct. The squeegee assembly, water-isolating assembly, and water spraying assembly are all disposed on the main body. The water-isolating assembly is located on the front side of the squeegee assembly along the cleaning direction of the floor brush device. A first suction port facing downwards from the main body is formed between the squeegee assembly and the water-isolating assembly. The water spraying assembly is connected to the side of the water-isolating assembly away from the squeegee assembly and forms a water spraying chamber with the water-isolating assembly. The water spraying chamber is disposed adjacent to the first suction port, and the water spraying assembly is configured to spray water into the water spraying chamber. The water spraying chamber has a water outlet facing downwards from the main body. In this way, the water-isolating assembly isolates the water spraying chamber from the first suction port. The negative pressure suction generated by the first suction port can draw the cleaning water dripping onto the surface to be cleaned from front to back through the water-isolating assembly and into the interior. During this process, the cleaning water will carry away dust and stains as it passes over the surface to be cleaned, achieving a good cleaning effect. There will be no wastewater residue on the floor brush device, avoiding the generation of odors when the floor brush device is placed after cleaning.
[0115] 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. Such modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the scope of the technical solutions of the embodiments of this application.
