Description

Technical Field

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

[0002] In related technologies, cleaning equipment includes a floor brush and a fan assembly. The fan assembly is connected to the floor brush via a hose. The fan assembly includes an interconnected motor and blades. The motor drives the blades to rotate, thereby generating negative pressure, which causes airflow to flow along the floor brush and the fan assembly to suck up dust from the floor.

[0003] However, air vortexes can easily form at the connection between the hose and the floor brush, which can increase the load on the motor and reduce the working efficiency of the fan assembly. Utility Model Content

[0004] Based on this, this application provides a floor brush structure and cleaning device to address the shortcomings of related technologies.

[0005] In a first aspect, this application provides a floor brush structure, comprising:

[0006] The housing has a wind chamber and a dust inlet, the wind chamber has a first air outlet, and the dust inlet, the wind chamber and the first air outlet are connected.

[0007] A connecting pipe is provided, one end of which is configured to be connected to the main unit of the cleaning equipment, and the other end of the connecting pipe has a first air inlet, which is positioned opposite to and connected to a first air outlet.

[0008] A flow guide is located at the connection between the first air outlet and the first air inlet. The flow guide has a flow guiding section to guide the fluid to flow axially along the first air inlet.

[0009] The floor brush structure provided in this embodiment includes a housing, a connecting pipe, and a flow guide. The housing includes an air chamber and a suction port. The air chamber includes a first air outlet, the connecting pipe includes a first air inlet, and the flow guide includes a flow guide portion. The suction port is designed to contact the surface to be cleaned, thereby removing dirt from the surface. The air chamber is designed to allow fluid flow, connecting the suction port and the connecting pipe. The connecting pipe connects the floor brush structure to the main unit of the cleaning equipment, allowing the main unit of the cleaning equipment to provide negative pressure suction. The first air outlet and the first air inlet connect the air chamber and the connecting pipe, allowing fluid to flow sequentially along the suction port, the connecting pipe, and the main unit of the cleaning equipment, thereby removing dirt from the surface to be cleaned. Because a guide section is provided at the junction of the first air outlet and the first air inlet, the fluid in the air chamber flows towards the first air outlet. When entering the junction of the first air outlet and the first air inlet, the guide section can guide the fluid to flow along the axial direction of the first air inlet, rather than rotating around the axial direction of the first air inlet. This can prevent the formation of a cyclone at the junction of the first air outlet and the first air inlet, thereby reducing the suction loss caused by turbulence and reducing the load on the main unit. As a result, the working efficiency and cleaning effect of the cleaning equipment can be improved.

[0010] In one possible implementation, at least part of the airflow guide is located inside the air cavity.

[0011] In this way, when the fluid in the air cavity flows toward the first air outlet, the flow direction is first changed by the guiding effect of the guide part, so that the fluid flows to the first air inlet along the axial direction of the first air inlet instead of rotating around the first air inlet, thereby preventing the formation of a cyclone at the first air outlet.

[0012] In one possible implementation, the flow guide includes at least two flow guide ribs, which are spaced apart circumferentially along the first air inlet, and a flow guide channel is defined between two adjacent flow guide ribs.

[0013] In this way, a flow channel is formed between two adjacent guide ribs, which guides the fluid to flow along the axial direction of the first air inlet, thereby preventing the fluid from rotating around the axial direction of the first air inlet and generating vortices, thus reducing the suction loss of the floor brush structure.

[0014] In one possible implementation, the guide ribs extend radially along the first air inlet.

[0015] In this way, the guide ribs can guide the radial flow of the first air inlet and then the axial flow of the first air inlet, thereby preventing the fluid from generating a cyclone at the junction of the first air outlet and the first air inlet, thus reducing the suction loss of the floor brush structure.

[0016] In one possible implementation, at least two guide ribs are symmetrically arranged along the first radial direction of the first air inlet; wherein the first radial direction is consistent with the height direction of the floor brush structure.

[0017] In this way, the interference of the guide ribs with the installation of the housing can be avoided.

[0018] In one possible implementation, the included angle between two adjacent guide ribs is greater than or equal to 25°, and the included angle between two adjacent guide ribs is less than or equal to 120°.

[0019] This helps control the direction of fluid flow, preventing the fluid from forming a cyclone at the first air outlet.

[0020] In one possible implementation, the flow guide is connected to at least one of the housing and the connecting pipe.

[0021] In this way, the flow guide can be installed on the housing or on the connecting pipe, or it can be connected to both the housing and the connecting pipe at the same time, thereby fixing the flow guide to the floor brush structure.

[0022] In one possible implementation, the guide plate further includes a support plate, with guide ribs connected to the side of the support plate facing the air cavity, and the support plate is connected to the first air outlet; the support plate has an clearance opening to connect the first air inlet and the first air outlet.

[0023] Thus, by connecting the support plate to the first air outlet, the guide component can be fixed to the housing and used to support multiple guide ribs so that the guide ribs can be set inside the air cavity.

[0024] In one possible implementation, the guide member further includes a connecting part with open ends. A support plate is connected to the end of the connecting part facing the air cavity, and the end of the connecting part facing the air cavity is connected to an avoidance opening. The end of the connecting part away from the air cavity is connected to a first air inlet.

[0025] Thus, the first air inlet can be connected to the first air outlet through a guide member. The guide member can act as a connector between the first air inlet and the first air outlet, and it can prevent the fluid from flowing axially around the first air inlet.

[0026] In one possible implementation, the connection includes a plug tube that plugs into the first air inlet.

[0027] Thus, the connecting part can be connected to the connecting pipe by setting a plug-in pipe, thereby connecting the connecting part to the connecting pipe and connecting the first air inlet and the first air outlet through the plug-in pipe.

[0028] In one possible implementation, the insertion pipe includes a pipe body and a fixing rib, the fixing rib being connected to the outer wall of the pipe body; the pipe body is inserted into the first air inlet, and the fixing rib abuts against the side wall of the first air inlet.

[0029] In this way, the connector can be inserted into the first air inlet, thereby connecting the connector to the first air inlet and the first air outlet.

[0030] In one possible implementation, the first air outlet is provided with a snap-fit ​​groove, and the support plate snaps into the snap-fit ​​groove.

[0031] In this way, the support plate can be snapped into the first air outlet, thereby connecting the air guide to the first air outlet and installing the air guide onto the housing.

[0032] In one possible implementation, the guide also includes an ear that is connected to the side of the support plate facing the insertion tube;

[0033] The ear has a positioning hole, and the housing has a positioning post, which is inserted into the positioning hole.

[0034] Thus, when installing the air guide, the positioning pin and positioning hole can be used to initially position the air guide on the housing, so that the subsequent support plate can be engaged with the first air outlet.

[0035] In some embodiments, the main unit further includes a dust cup assembly connected to the cover and having a dust collection chamber connected to the fan assembly, thereby allowing fluid to flow sequentially through the suction port, air chamber, first air outlet, connecting pipe, dust collection chamber and fan assembly. The fluid can flow to the fan assembly after dust and gas are separated by the dust cup assembly.

[0036] In some embodiments, the floor brush structure further includes a dust cup assembly connected to the housing. The dust cup assembly has a dust collection chamber, and the suction port, dust collection chamber, air chamber, and connecting pipe are connected in sequence.

[0037] In this way, the fluid can flow sequentially along the suction port, dust collection chamber, air chamber, and connecting pipe to remove dirt from the surface to be cleaned. The dust cup assembly can be used to collect dirt and perform dust-air separation on the fluid entering the dust collection chamber. Because the dust cup assembly is located close to the surface to be cleaned, the flow path of dirt to the dust collection chamber is shortened, and dirt can be prevented from clogging the connecting pipe.

[0038] In one possible implementation, the housing has a suction chamber with one side open to form a suction port, and a second air outlet on the other side of the suction chamber.

[0039] The dust collection chamber has a second air inlet, which is positioned opposite to and abuts against the second air outlet, so that the dust collection chamber and the suction chamber are connected.

[0040] In this way, when the floor brush structure is vacuuming, the fluid flows sequentially along the suction chamber, dust collection chamber, air chamber, connecting pipe and the main unit of the cleaning equipment to suck up the dirt on the surface to be cleaned. In addition, the second air inlet and the second air outlet are directly connected to eliminate the intermediate pipe, thereby shortening the path of dirt on the surface to be cleaned to the dust collection chamber, thus improving the vacuuming effect of the floor brush structure.

[0041] Secondly, this application provides a cleaning device, including a main unit and the floor brush structure provided in the first aspect, wherein the floor brush structure is connected to the main unit.

[0042] In addition to the technical problems solved by the embodiments of this application, the technical features constituting the technical solutions, and the beneficial effects brought about by the technical features of these technical solutions described above, other technical problems that can be solved by the floor brush structure and cleaning equipment provided by this application, other technical features included in the technical solutions, and the beneficial effects brought about by these technical features will be further explained in detail in the specific embodiments.

[0072] To make the objectives, technical solutions, and advantages of this application clearer, the technical solutions in the embodiments of this application will be described in more detail below with reference to the accompanying drawings. In the drawings, the same or similar reference numerals denote the same or similar components or components having the same or similar functions throughout.

The embodiments described below with reference to the accompanying drawings are exemplary and intended to explain this application, and should not be construed as limiting this application. All other embodiments obtained by those skilled in the art based on the embodiments of this application without creative effort are within the scope of protection of this application. The embodiments of this application will be described in detail below with reference to the accompanying drawings.

[0073] 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.

[0074] 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 accompanying drawings, and 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, and therefore should not be construed as a limitation of this application.

[0075] 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.

[0076] Furthermore, the terms “comprising” and “having”, and any variations thereof, are intended to cover non-exclusive inclusion, such that a process, method, system, product, or display that includes a series of steps or units is 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 display.

[0077] In related technologies, cleaning equipment includes a floor brush and a fan assembly. The fan assembly is connected to the floor brush via a hose. The fan assembly includes an interconnected motor and blades. The motor drives the blades to rotate, thereby generating negative pressure, which causes airflow to flow along the floor brush and the fan assembly to suck up dust from the floor.

[0078] However, air vortexes can easily form at the connection between the hose and the floor brush, which can increase the load on the motor and reduce the working efficiency of the fan assembly.

[0079] In view of the above problems, this application provides a floor brush structure and a cleaning device. The floor brush structure provides a guide at the connection between the first air outlet and the first air inlet. The guide guides the fluid in the air chamber to enter the first air inlet and flow along the axial direction of the first air inlet, thereby preventing the fluid from rotating circumferentially along the first air inlet and generating a cyclone, thereby improving the dust collection efficiency of the cleaning device.

[0080] The following combination Figures 1 to 19 The specific implementation methods of the floor brush structure and cleaning equipment provided in the embodiments of this application will be described in detail.

[0081] Reference Figures 1 to 6 As shown in the figure, this application embodiment provides a cleaning device, which includes a main unit 20 and a floor brush structure 10, the floor brush structure 10 being connected to the main unit 20.

[0082] The main unit 20 may include a cover 201, a fan assembly 202, a handle 203, and a battery assembly 204. The fan assembly 202 is used to provide negative pressure suction, and the battery assembly 204 is used to power the fan assembly 202. The fan assembly 202 and the battery assembly 204 are disposed inside the cover 201. The handle 203 is inserted into the cover 201 and connected to the cover 201, so that the user can move the main unit 20 and the floor brush structure 10 together by operating the handle 203.

[0083] Reference Figures 1 to 14 As shown, based on the above embodiments, this application also provides a floor brush structure 10. The floor brush structure 10 includes a housing 100, a connecting pipe 200, and a guide member 300. The housing 100 has an air chamber 110 and a dust suction port 121. The air chamber 110 has a first air outlet 111. The dust suction port 121, the air chamber 110, and the first air outlet 111 are sequentially connected. One end of the connecting pipe 200 is configured to be connected to the main unit 20 of the cleaning equipment, and the other end of the connecting pipe 200 has a first air inlet 210. The first air inlet 210 and the first air outlet 111 are opposite to each other and connected.

[0084] The flow guide 300 is located at the connection between the first air outlet 111 and the first air inlet 210, and is connected to at least one of the housing 100 and the connecting pipe 200. The flow guide 300 has a flow guide portion 310 to guide the fluid to flow axially along the first air inlet 210.

[0085] It should be noted that mixtures of impurities such as gas, water stains, dust, and particles can be collectively referred to as fluids.

[0086] In this embodiment, the housing 100 is used to define the air outlet 110 and the suction port 121, thereby guiding the fluid to flow along the suction port 121 and the air outlet 110. The connecting pipe 200 is used to connect the housing 100 and the main unit 20, thereby connecting the air outlet 110 and the fan assembly 202, so that the fan assembly 202 provides power to drive the fluid to flow along the air outlet 110, the connecting pipe 200 and the fan assembly 202.

[0087] The air cavity 110 has a first air outlet 111 on the side facing the connecting pipe 200, and the connecting pipe 200 has a first air inlet 210 on the end facing the air cavity 110. When the first air outlet 111 and the first air inlet 210 are connected, the connecting pipe 200 can connect the air cavity 110 and the main unit 20.

[0088] It should be noted that if the first air outlet 111 and the first air inlet 210 are directly connected or abutted, when fluid flows towards the first air outlet 111, because the first air outlet 111 gradually narrows or suddenly narrows relative to other parts of the air cavity 110, the fluid flows from an open area to a narrow area. The relatively narrow first air outlet 111 will accelerate the fluid flow rate and cause the fluid flow to be unstable. This can easily lead to the formation of a cyclone at the connection between the first air outlet 111 and the first air inlet 210. This will increase the energy loss of the floor brush structure 10 and increase the load on the main unit 20, thereby reducing the cleaning effect of the cleaning equipment. Furthermore, the cyclone will cause the cleaning equipment to generate significant noise during operation, thus affecting the user experience.

[0089] Therefore, in this embodiment, a guide member 300 is provided at the connection between the first air outlet 111 and the first air inlet 210. The guide member 300 includes a guide portion 310. When the fluid flows from the side of the air chamber 110 away from the first air outlet 111 toward the first air outlet 111, the guide portion 310 can guide the fluid to flow along the extension direction of the first air outlet 111, thereby preventing the formation of a cyclone at the connection between the first air outlet 111 and the first air inlet 210 due to the circumferential rotation of the fluid along the first air outlet 111. This reduces the energy loss of the floor brush structure 10 and the load on the main unit 20, thereby improving the working efficiency and cleaning effect of the cleaning equipment.

[0090] The floor brush structure 10 provided in this application embodiment includes a housing 100, a connecting pipe 200, and a guide member 300. The housing 100 includes an air chamber 110 and a dust suction port 121. The air chamber 110 includes a first air outlet 111. The connecting pipe 200 includes a first air inlet 210. The guide member 300 includes a guide section 310. By providing a suction port 121 to contact the surface to be cleaned, dirt is sucked away. By providing a ventilation chamber 110 for fluid flow, the suction port 121 and the connecting pipe 200 are connected. The connecting pipe 200 is also connected to the floor brush structure 10 and the main unit 20 of the cleaning equipment. The main unit 20 of the cleaning equipment provides negative pressure suction. By providing a first air outlet 111 and a first air inlet 210 to connect the ventilation chamber 110 and the connecting pipe 200, fluid flows sequentially along the suction port 121, the ventilation chamber 110, the first air outlet 111, the first air inlet 210, and the main unit 20 of the cleaning equipment, thereby sucking away dirt from the surface to be cleaned. Because a guide section 310 is provided at the junction of the first air outlet 111 and the first air inlet 210, the fluid in the air chamber 110 flows toward the first air outlet 111. When entering the junction of the first air outlet 111 and the first air inlet 210, the guide section 310 can guide the fluid to flow along the axial direction of the first air inlet 210, rather than rotating around the axial direction of the first air inlet 210. This can prevent the formation of a cyclone at the junction of the first air outlet 111 and the first air inlet 210, thereby reducing the suction loss caused by turbulence. In this way, the dust collection effect of the cleaning equipment can be improved.

[0091] Reference Figure 8 As shown, in some embodiments, at least a portion of the guide portion 310 is located within the air cavity 110. That is, the guide portion 310 may be entirely located within the air cavity 110 or partially located within the air cavity 110. In this way, when the fluid in the air cavity 110 flows toward the first air outlet 111, the flow direction is first changed by the guiding effect of the guide portion 310, so that the fluid flows axially along the first air inlet 210 to the first air inlet 210, rather than rotating circumferentially along the first air inlet 210, thereby preventing the formation of a cyclone at the connection between the first air outlet 111 and the first air inlet 210.

[0092] Reference Figures 9 to 12 As shown, in one possible implementation, the flow guide 310 includes at least two flow guide ribs 311, which are spaced apart circumferentially along the first air inlet 210, and a flow guide channel 312 is defined between two adjacent flow guide ribs 311.

[0093] It is understood that two adjacent guide ribs 311 form a guide channel 312. At least two guide ribs 311 can define at least two guide channels 312. Fluid can be diverted to multiple guide channels 312 and flow along the guide channels 312, thereby guiding the fluid to flow along the axial direction of the first air inlet 210, thereby preventing the fluid from rotating around the axial direction of the first air inlet 210 and generating vortices, thereby reducing the suction loss of the floor brush structure 10.

[0094] In one possible implementation, the guide ribs 311 extend radially along the first air inlet 210. Thus, the guide channels 312 defined by adjacent guide ribs 311 also extend radially along the first air inlet 210, preventing the fluid from rotating axially around the first air inlet 210 and allowing the fluid to flow radially along the first air inlet 210 and then axially, thereby preventing the formation of an air vortex at the junction of the first air outlet 111 and the first air inlet 210, thereby reducing the suction loss of the floor brush structure 10.

[0095] In some embodiments, at least two guide ribs 311 are symmetrically arranged along the first radial direction of the first air inlet 210. The first radial direction is consistent with the height direction of the floor brush structure 10, and can be referenced from... Figure 10 The X direction in the equation.

[0096] It should be noted that the housing 100 includes an upper cover 100a and a bottom cover 100b. The upper cover 100a and the bottom cover 100b are arranged along the height direction of the floor brush structure 10. The upper cover 100a and the bottom cover 100b are processed and formed separately and then assembled into the housing 100. This is beneficial for processing and assembly. If the flow guide 300 is provided with flow guide ribs 311 on both sides of the first radial direction, the flow guide ribs 311 will affect the assembly of the upper cover 100a and the bottom cover 100b.

[0097] Therefore, in this embodiment, the guide ribs 311 can be arranged symmetrically along the first radial direction of the first air inlet 210. When the fluid flows along the cavity wall of the air chamber 110 to the first air outlet 111, the guide ribs 311 on both sides can guide the fluid to flow towards the center of the first air outlet 111, thereby making the fluid flow along the axial direction of the first air inlet 210, and can avoid the guide ribs 311 interfering with the assembly of the housing 100.

[0098] For example, there can be at least four guide ribs 311. A guide channel 312 can be defined between two adjacent guide ribs 311. At least four guide ribs 311 can define at least five guide channels 312, thereby splitting a large fluid into multiple smaller fluids. The guide ribs 311 are symmetrically distributed on both sides of the first air inlet 210, which is conducive to forming multiple guide channels 312 of uniform size so that the fluid can flow evenly to the connecting pipe 200.

[0099] In some embodiments, the included angle between two adjacent guide ribs 311 is greater than or equal to 25°, and the included angle between two adjacent guide ribs 311 is less than or equal to 120°. This helps to control the flow direction of the fluid and prevent the fluid from forming a cyclone at the first air outlet 111.

[0100] It should be noted that multiple guide ribs 311 can be evenly spaced along the circumference of the first air inlet 210, and the included angle between two adjacent guide ribs 311 is between 25° and 45°.

[0101] Alternatively, multiple guide ribs 311 can be symmetrically arranged along the first radial direction to form an X-shaped or *-shaped guide portion 310, for example, Figure 10 The schematic flow guide 310 includes six flow guide ribs 311, which are symmetrically arranged along the X direction. Three flow guide ribs 311 are provided on the left side of the X direction, and the included angle between two adjacent flow guide ribs 311 is 30°. Three flow guide ribs 311 are also provided on the right side of the X direction, and the included angle α between two adjacent flow guide ribs 311 is 30°. The included angle β between the first flow guide rib 311 on the left and the first flow guide rib 311 on the right is 120°.

[0102] Reference Figures 8 to 12 As shown, the air guide 300 also includes a support plate 313, and air guide ribs 311 are connected to the side of the support plate 313 facing the air cavity 110. The support plate 313 is connected to the first air outlet 111, and the support plate 313 has an clearance opening to connect the first air inlet 210 and the first air outlet 111. In this way, by connecting the support plate 313 to the first air outlet 111, the air guide 300 can be fixed to the housing 100 and used to support the multiple air guide ribs 311 so that the air guide ribs 311 are arranged in the air cavity 110.

[0103] Reference Figures 8 to 12 As shown, in one possible implementation, the guide member 300 further includes a connecting part 320. The guide part 310 is connected to the connecting part 320. The connecting part 320 is open at both ends. The support plate 313 is connected to the end of the connecting part 320 facing the air cavity 110. The end of the connecting part 320 facing the air cavity 110 is connected to the clearance opening. The end of the connecting part 320 away from the air cavity 110 is connected to the first air inlet 210. The first air inlet 210 is connected to the first air outlet 111 through the connecting part 320.

[0104] Thus, the first air inlet 210 can be connected to the first air outlet 111 through the guide 300. The guide 300 can act as a connector between the first air inlet 210 and the first air outlet 111, and the guide 300 can prevent the fluid from flowing around the first air inlet 210 axially, thereby reducing the turbulent energy loss of the floor brush structure 10.

[0105] Reference Figures 8 to 12 As shown, in one possible implementation, the connecting part 320 includes a plug pipe 321, which is plugged into the first air inlet 210. Thus, the connecting part 320 can be connected to the connecting pipe 200 by plugging the plug pipe 321, thereby connecting the connecting part 320 to the connecting pipe 200 and connecting the first air inlet 210 and the first air outlet 111 through the plug pipe 321.

[0106] Reference Figure 8 and Figure 11 As shown, in one possible implementation, the insertion pipe 321 includes a pipe body 3211 and a fixing rib 3212, with the fixing rib 3212 connected to the outer wall of the pipe body 3211. The pipe body 3211 is inserted into the first air inlet 210, and the fixing rib 3212 abuts against the side wall of the first air inlet 210.

[0107] This configuration allows the connector 321 to be connected to the first air inlet 210, thereby connecting the connector 321 to the first air inlet 210 and the first air outlet 111, thus enabling the first air inlet 210 and the first air outlet 111 to be connected and aligned.

[0108] In some embodiments, the first air outlet 111 is provided with a snap-fit ​​groove, and the support plate 313 snaps into the snap-fit ​​groove. It is understood that the first air outlet 111 is defined by the upper cover 100a and the bottom shell 100b, and the first air inlet 210 is provided with a snap-fit ​​groove. Therefore, when assembling the upper cover 100a and the bottom shell 100b, the support plate 313 can be snapped into the snap-fit ​​groove, thereby connecting the connecting part 320 to the first air outlet 111, and connecting the guide 300 to the housing 100. Thus, the connecting part 320 can connect the housing 100 and the connecting pipe 200.

[0109] Reference Figure 9 , Figure 11 and Figure 12 As shown, in one possible implementation, the guide 300 further includes an ear 330, which is connected to the side of the support plate 313 facing the insertion tube 321. The ear 330 has a positioning hole 331, and the housing 100 is provided with a positioning post, which is inserted into the positioning hole 331.

[0110] In this way, when installing the air guide 300, the positioning pin and positioning hole 331 can be used to make the air guide 300 initially positioned on the housing 100, so that the subsequent support plate 313 can be snapped into the first air outlet 111, or the insertion pipe 321 can be inserted into the first air inlet 210.

[0111] For example, an ear 330 can be provided on each radial side of the insertion pipe 321, and each ear 330 is provided with a positioning hole 331. It should be noted that in some embodiments, the cleaning device may also include a dust cup assembly 400, which can be installed on the handle 203 or the cover 201. The dust cup assembly 400 is connected to the air chamber 110 through the connecting pipe 200 and is also connected to the fan assembly 202. In this way, during vacuuming, the airflow flows sequentially along the suction port 121, the air chamber 110, the connecting pipe 200, the dust cup assembly 400, and the fan assembly 202.

[0112] Reference Figures 2 to 6 , Figures 15 to 19 As shown, in some embodiments, the floor brush structure 10 further includes a dust cup assembly 400, which is connected to the housing 100. The dust cup assembly 400 has a dust collection chamber 411, and the suction port 121, the dust collection chamber 411, the air chamber 110, and the connecting pipe 200 are connected in sequence.

[0113] With this configuration, fluid can flow sequentially along the suction port 121, the dust collection chamber 411, the air chamber 110, and the connecting pipe 200 to suck up dirt from the surface to be cleaned. The dust cup assembly 400 can be used to collect dirt and perform dust-air separation on the fluid entering the dust collection chamber 411.

[0114] The housing 100 may be provided with a mounting groove 150 for mounting the dust cup assembly 400. The dust cup assembly 400 may include a dust collection cup 410, a cyclone cone 420, and a filter unit 430. The inner wall of the dust collection cup 410 defines a dust collection chamber 411. The cyclone cone 420 is disposed in the dust collection chamber 411 to separate dust and gas from the fluid entering the dust collection chamber 411. The filter unit 430 is used to filter the fluid discharged from the dust collection chamber 411 to prevent small particulate solids (such as dust) from continuing to flow to the main unit 20.

[0115] The dust cup assembly 400 may also include a locking release member 440, which is connected to one end of the dust cup 410. A locking part that cooperates with the locking release member 440 can be provided in the mounting groove 150. When the locking release member 440 is connected to the locking part, the dust cup assembly 400 can be fixed on the housing 100 as a whole. When the locking release member 440 is disengaged from the locking part, the dust cup assembly 400 can be removed from the housing 100 for easy cleaning.

[0116] Reference Figure 16 As shown, in some embodiments, the housing 100 has a suction chamber 120, one side of which is open to form a suction port 121, and the other side of which has a second air outlet 122. The dust collection chamber 411 has a second air inlet 4111, which is opposite to and abuts against the second air outlet 122, so that the suction chamber 120 and the dust collection chamber 411 are in communication.

[0117] Thus, when the floor brush structure 10 is vacuuming, the fluid flows sequentially along the suction chamber 120, the dust collection chamber 411, the air chamber 110, the connecting pipe 200, and the main unit 20 to suck up the dirt on the surface to be cleaned. Furthermore, the second air inlet 4111 is directly connected to the second air outlet 122 to eliminate the intermediate pipe, thereby shortening the path of dirt on the surface to be cleaned to the dust collection chamber 411 and improving the vacuuming effect of the floor brush structure 10.

[0118] Reference Figures 4 to 6 , Figure 13 As shown, in one possible implementation, the floor brush structure 10 further includes a first seal 500, and the housing 100 has a first sealing groove 130 surrounding the outer periphery of the second air outlet 122. The first seal 500 is disposed in the first sealing groove 130 and abuts against the dust cup assembly 400 to seal the gap between the second air outlet 122 and the second air inlet 4111.

[0119] In other words, the first sealing groove 130 and the second air outlet 122 can both be located on the groove wall of the mounting groove 150. When the dust cup assembly 400 is installed into the mounting groove 150 and the second air outlet 122 and the second air inlet 4111 are correctly connected, the first sealing member 500 can seal the gap between the second air outlet 122 and the second air inlet 4111 to prevent fluid from leaking from the gap between the second air outlet 122 and the second air inlet 4111, thereby improving the dust collection effect of the floor brush structure 10.

[0120] Reference Figure 13 , Figure 18 , Figure 19 As shown, in some embodiments, the air chamber 110 further has a third air inlet 112, and the dust collection chamber 411 further has a third air outlet 4112. The third air outlet 4112 abuts against and communicates with the third air inlet 112, so that the dust collection chamber 411 and the air chamber 110 are connected.

[0121] Thus, when the dust cup assembly 400 is correctly installed into the mounting slot 150, the second air outlet 122 and the second air inlet 4111 can be directly connected, allowing the suction chamber 120 and the dust collection chamber 411 to communicate. Similarly, the third air outlet 4112 can be directly connected to the third air inlet 112, allowing the dust collection chamber 411 and the air chamber 110 to communicate. This, in turn, allows the suction chamber 120, the dust collection chamber 411, the air chamber 110, and the connecting pipe 200 to be sequentially connected, enabling fluid to flow sequentially along the suction chamber 120, the integrated chamber, the air chamber 110, and the connecting pipe 200. (Refer to...) Figures 4 to 6 , Figure 13 As shown, in some embodiments, the floor brush structure 10 further includes a second seal 600, and the housing 100 has a second sealing groove 140 surrounding the outer periphery of the third air inlet 112. The second seal 600 is disposed in the second sealing groove 140 and abuts against the dust cup assembly 400 to seal the gap between the third air inlet 112 and the third air outlet 4112.

[0122] Thus, when the dust cup assembly 400 is installed into the housing 100 and the third air outlet 4112 and the third air inlet 112 are connected, the second seal 600 can seal the gap between the third air outlet 4112 and the third air inlet 112 to prevent fluid from leaking from the gap between the third air outlet 4112 and the third air inlet 112, thereby improving the dust collection effect of the floor brush structure 10.

[0123] Reference Figure 19 As shown, it should be noted that the dust collection cup 410 may include a first cup body 410a and a second cup body 410b. After the first cup body 410a and the second cup body 410b are connected, they can jointly define the dust collection chamber 411. A third seal 450 may be provided at the connection between the first cup body 410a and the second cup body 410b to prevent fluid from leaking from the gap between the first cup body 410a and the second cup body 410b.

[0124] In one possible implementation, the third air inlet 112 is provided with at least one partition rib, which divides the third air inlet 112 into at least two sub-air inlets.

[0125] With this configuration, when the fluid in the dust collection chamber 411 enters the air chamber 110 through the third air inlet 112, the partition ribs can disperse a large stream of fluid into multiple smaller streams, preventing the fluid from forming a cyclone at the interface between the third air inlet 112 and the third air outlet 4112. Furthermore, the partition ribs can be used to fix structures such as filter foam, thereby preventing solids in the dust collection chamber 411 from continuing to flow into the air chamber 110.

[0126] 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.
