Description

Technical Field

[0001] This application relates to the field of household appliance technology, and in particular to a floor brush structure and cleaning device. Background Technology

[0002] Cleaning equipment (such as vacuum cleaners and floor scrubbers) can suck up dust and dirt from the ground to keep it clean.

[0003] In related technologies, cleaning equipment includes a main body and a floor brush structure, the floor brush structure having a suction port. When the cleaning equipment is running, suction is generated at the suction port, drawing dust and dirt into the floor brush structure to achieve cleaning.

[0004] However, the suction power of the floor brush structure gradually weakens from the suction port towards both sides of the width of the floor brush structure, resulting in uneven suction power distribution. Utility Model Content

[0005] This application provides a floor brush structure and cleaning equipment to solve the problem of uneven suction distribution in existing floor brush structures.

[0006] In a first aspect, embodiments of this application provide a floor brush structure, including:

[0007] The housing has a suction port.

[0008] The air intake is located at the front end of the housing in the direction of travel. The air intake has an air intake channel with a first angle between the air intake channel and the direction of travel of the housing. The air intake covers the suction port and directs the airflow into the suction port.

[0009] Thus, the floor brush structure provided in this application embodiment has a suction port on its housing, and a guide member corresponding to the suction port is provided on the front side along the traveling direction of the housing. The guide member covers the suction port and has a guide channel with a first angle along the traveling direction of the housing. Therefore, when the cleaning equipment is running and the suction port of the floor brush structure generates suction, the airflow will flow towards the suction port. When the airflow reaches the guide member, the guide member guides the airflow to the side of the suction port through the first angle, and then flows into the suction port. Compared to the prior art where the airflow directly enters the suction port, resulting in greater suction at the suction port than on both sides, the floor brush structure provided in this application embodiment can guide a portion of the airflow directly flowing towards the suction port to at least one side of the suction port, thereby relatively reducing the airflow directly flowing towards the suction port and decreasing the suction, while relatively increasing the airflow on at least one side of the suction port and increasing the suction, thus balancing the suction of the floor brush structure.

[0010] In one possible implementation, the floor brush structure provided in this application embodiment further includes a dust cup assembly, which is disposed on the housing and is connected to the suction port through an air duct.

[0011] This allows the dust cup assembly to be closer to the suction port, resulting in better dust collection efficiency.

[0012] In one possible implementation, the floor brush structure provided in this application embodiment has an air inlet in the dust cup assembly, which is connected to the suction port through an air duct.

[0013] This allows the cleaning equipment to operate more smoothly, preventing dust and dirt from entering other parts of the cleaning equipment.

[0014] In one possible implementation, the floor brush structure provided in this application embodiment has a straight air duct, with the air inlet and suction port located in the extension direction of the air duct.

[0015] This reduces the number of bends in the air duct, thereby reducing airflow resistance and improving suction efficiency.

[0016] In one possible implementation, the floor brush structure provided in this application embodiment has a through groove on the drainage component, and the through groove forms a drainage channel;

[0017] Alternatively, the drainage device includes a first drainage rib and a plurality of second drainage ribs, the plurality of second drainage ribs being respectively spaced apart on opposite sides of the first drainage rib, and drainage channels being formed between two adjacent second drainage ribs, as well as between the first drainage rib and the second drainage rib adjacent to the first drainage rib;

[0018] Alternatively, the drainage device includes multiple second drainage ribs, which are arranged sequentially at intervals, and a drainage channel is formed between two adjacent second drainage ribs.

[0019] In this way, the flow guide can be formed into three types of structures, making the structure of the flow guide more flexible and diverse, with a wider range of applications. It ensures a balanced suction effect on the suction port and provides a clear flow path for the airflow through the flow guide channel. It can accurately guide the surrounding airflow to the suction port, allowing the airflow to flow orderly along the flow guide channel, avoiding disorderly diffusion and turbulence of the airflow.

[0020] In one possible implementation, the floor brush structure provided in this application embodiment has a plurality of through grooves on the second drainage rib. The plurality of through grooves are spaced apart along the extension direction of the second drainage rib, and the through grooves connect two adjacent drainage channels.

[0021] This makes the second guide ribs more effective at guiding airflow. Two adjacent rows of second guide ribs can relay the airflow, allowing the airflow to flow more smoothly from the front end of the guide to the side of the suction port, reducing airflow loss and turbulence.

[0022] In one possible implementation, the bottom of the through groove on the second guide rib of the floor brush structure provided in this application extends to the housing.

[0023] This allows for greater airflow at the second drainage rib, further improving the smoothness of airflow.

[0024] In one possible implementation, the floor brush structure provided in this application embodiment has a first included angle greater than or equal to 0° and less than or equal to 50°.

[0025] In this way, the airflow collection range can be expanded, allowing the airflow to flow more fully to at least one side of the suction port under the action of the second guide rib and the guide end.

[0026] In one possible implementation, the floor brush structure provided in this application embodiment has parallel drainage channels;

[0027] Alternatively, the drainage channels located on the same side as the first drainage rib are parallel to each other.

[0028] This allows for more orderly airflow and reduces turning and turbulence.

[0029] In one possible implementation, the floor brush structure provided in this application embodiment has each drainage channel inclined relative to the housing surface toward the first drainage rib.

[0030] This further increases the side surface area of ​​the second airflow guide, allowing for more thorough contact with the airflow and optimizing the airflow path to better guide the airflow to the side of the suction port.

[0031] In one possible implementation, the floor brush structure provided in this application embodiment has each drainage channel symmetrically arranged relative to the first drainage rib.

[0032] This allows for a more balanced and consistent distribution of airflow and suction on both sides of the inlet.

[0033] In one possible implementation, the floor brush structure provided in this application embodiment has a drainage channel width greater than or equal to 1 mm and less than or equal to 1.6 mm.

[0034] Thus, a suitable width range ensures that the airflow maintains an appropriate speed within the drainage channel.

[0035] In one possible implementation, the floor brush structure provided in this application embodiment has a drainage channel in which the width of the drainage channel gradually increases from the side away from the suction port to the side facing the suction port.

[0036] This allows the airflow to gradually accelerate as it flows toward the suction port, thus enabling dust, dirt, and other contaminants to be sucked into the suction port more quickly.

[0037] In one possible implementation, the floor brush structure provided in this application embodiment has a protrusion in the drainage element, and the protrusion has a second included angle along the traveling direction of the housing.

[0038] In this way, the airflow that flows directly to the suction port can be dispersed into two parts by the protrusion, and guided to the two sides of the suction port by the first guide rib, thereby increasing the suction force on the opposite sides of the suction port.

[0039] In one possible implementation, the floor brush structure provided in this application embodiment has each second drainage rib having a drainage end, the drainage end being away from the suction port, and each drainage end having a first distance from the suction port;

[0040] Each first distance decreases sequentially towards at least one of the opposite sides of the suction port.

[0041] In this way, the airflow can form an orderly gradient as it flows from the inlet to the outlet, allowing the airflow to converge at the outlet in a layered and orderly manner, avoiding airflow chaos and mutual interference, and improving the airflow guidance efficiency.

[0042] In one possible implementation, the floor brush structure provided in this application embodiment has a first distance greater than or equal to 31mm and less than or equal to 60mm.

[0043] In this way, the airflow can be guided by the inlet to flow towards the suction port at a suitable speed and direction, optimizing the airflow distribution and enhancing the overall suction effect of the suction port.

[0044] In one possible implementation, the floor brush structure provided in this application embodiment has a sloping end that is inclined toward the suction port.

[0045] This allows the airflow to flow smoothly towards the inlet along the slope when it comes into contact with the inlet.

[0046] In one possible implementation, the floor brush structure provided in this application embodiment has inclined surfaces located in the same plane, and the plane has a third angle with the direction of travel of the shell.

[0047] This can further improve the smoothness and consistency of airflow along the guide end.

[0048] In one possible implementation, the brush structure provided in this application embodiment has the second drainage rib inclined relative to the housing surface toward the first drainage rib.

[0049] This further increases the side surface area of ​​the second airflow guide, allowing for more thorough contact with the airflow and optimizing the airflow path to better guide the airflow to the side of the suction port.

[0050] In one possible implementation, the floor brush structure provided in this application embodiment has a through groove on the first drainage rib, and the through groove forms a drainage channel facing the suction port;

[0051] Alternatively, a drainage channel may be formed between two adjacent second drainage ribs;

[0052] Alternatively, drainage channels may be formed between two adjacent second drainage ribs, as well as between the first drainage rib and the second drainage rib adjacent to the first drainage rib.

[0053] In this way, a clear flow path is provided for the airflow, which can accurately guide the surrounding airflow to the inlet, allowing the airflow to flow orderly along the guide channel, avoiding disorderly diffusion and turbulence.

[0054] In one possible implementation, the floor brush structure provided in this application embodiment has a second distance between the end of the first guide rib facing the suction port and the suction port, and a third distance between the end of each second guide rib facing the suction port and the suction port.

[0055] The second distance and each of the third distances are equal;

[0056] Alternatively, all third distances are equal, and the third distance is less than the second distance.

[0057] Thus, the second distance and the third distance are equal, which can form a uniform and stable airflow field at the inlet; the third distances are equal and the third distance is smaller than the second distance, which can enable the airflow guided by the second guide rib to reach the inlet faster and more directly.

[0058] In one possible implementation, the floor brush structure provided in this application embodiment has a third distance between the end of each second guide rib facing the suction port and the suction port, and each third distance is equal;

[0059] Alternatively, each third distance decreases sequentially from one side of each second drainage rib to the other side.

[0060] Thus, when the third distances are equal, the airflow can converge to the inlet along the distribution gradient of the guide end, forming a uniform and stable airflow field at the inlet; while when the third distances decrease in sequence, the length of each second guide rib is shorter, causing the airflow to form a stronger suction on the corresponding side of the inlet.

[0061] In one possible implementation, the floor brush structure provided in this application embodiment has a third distance greater than or equal to 15mm and less than or equal to 44.5mm.

[0062] This distance range allows the airflow sufficient space to buffer, preventing airflow turbulence or vortex formation caused by direct impact on the intake.

[0063] In one possible implementation, the distance between the side of the drainage element away from the housing and the housing in the floor brush structure provided in this application embodiment is greater than or equal to 0.5 mm and less than or equal to 1.2 mm.

[0064] This avoids the slight undulations on the surface to be cleaned from affecting the vacuuming effect, and also avoids frequent friction between the vacuum guide and the surface to be cleaned.

[0065] In one possible implementation, the floor brush structure provided in this application embodiment has a drainage soft rubber component.

[0066] This avoids excessive collisions between the drainage components and solid particles, thus improving the cleaning effect.

[0067] In one possible implementation, the floor brush structure provided in this application embodiment has a Shore hardness of 45A or greater and 85A or less for the drainage soft rubber component.

[0068] This ensures that the soft rubber parts will not be excessively deformed or damaged when subjected to airflow impact and external pressure.

[0069] In one possible implementation, the floor brush structure provided in this application embodiment has the drainage component and the housing integrally formed;

[0070] Alternatively, the housing has a mounting section, and the drainage element is disposed on the mounting section;

[0071] Alternatively, the drainage component can be bonded to the housing.

[0072] In this way, the installation method of the drainage device can be flexibly selected according to the installation requirements, ensuring the convenience of installation and use of the drainage device.

[0073] In one possible implementation, the brush structure provided in this application has its suction port located on one side of the centerline in the direction of travel of the housing.

[0074] This provides more space for the layout of components such as the dust cup assembly on the floor brush structure, making the entire device more compact.

[0075] In one possible implementation, the floor brush structure provided in this application embodiment has a housing with a receiving groove, a suction port in the receiving groove, and a draining member on the front side of the receiving groove along the traveling direction of the housing.

[0076] In this way, a relatively ample negative pressure adsorption space can be formed in front of the suction port, so that the suction range is larger.

[0077] Secondly, embodiments of this application provide a cleaning device, including a cleaning device body and any of the above-described floor brush structures disposed on the cleaning device body.

[0078] The floor brush structure and cleaning device provided in this application embodiment have a suction port on the housing of the floor brush structure. A guide member corresponding to the suction port is provided on the front side of the housing along the direction of travel of the housing. The guide member covers the suction port and has a first angle along the direction of travel of the housing, so that at least part of the side of the guide member away from the suction port is inclined relative to the direction of travel of the housing. In this way, when the cleaning device is running and the suction port of the floor brush structure generates suction, the airflow will flow towards the suction port. When the airflow flows to the guide member, the structure formed by the first angle will guide the airflow to the side of the suction port and then into the suction port. Compared with the prior art where the airflow directly enters the suction port, resulting in the suction force at the suction port being greater than the suction force on both sides of the suction port, the floor brush structure provided in this application embodiment can guide part of the airflow that flows directly to the suction port to at least one side of the suction port, so that the airflow that flows directly to the suction port is relatively reduced, the suction force is reduced, and the airflow on at least one side of the suction port is relatively increased, the suction force is increased, so as to balance the suction force of the floor brush structure.

[0100] The accompanying drawings have illustrated specific embodiments of this application, which will be described in more detail below. These drawings and descriptions are not intended to limit the scope of the concept in any way, but rather to illustrate the concept of this application to those skilled in the art through reference to specific embodiments. Detailed Implementation

[0101] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this utility model, not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this utility model. In the absence of conflict, the following embodiments and features can be combined with each other.

[0102] The cleaning equipment consists of a main body and a floor brush structure, which has a suction port. When the cleaning equipment is running, suction is generated at the suction port, drawing dust and dirt into the floor brush structure to achieve cleaning.

[0103] However, the suction power of the floor brush structure gradually weakens from the suction port towards both sides of the width direction of the floor brush structure, resulting in greater suction power at the suction port and less suction power further away from the suction port. Furthermore, when the suction port of the floor brush structure is offset to one side of the width direction, the suction power on the offset side will be greater than that on the offset side, thus making the suction power distribution of the floor brush structure uneven.

[0104] To overcome the deficiencies in the prior art, the floor brush structure and cleaning device provided in this application embodiment have a suction port on the housing of the floor brush structure, and a guide member corresponding to the suction port is provided on the front side of the housing along the direction of travel. The guide member covers the suction port, and the guide member has a first angle along the direction of travel of the housing, such that at least part of the side of the guide member away from the suction port is inclined relative to the direction of travel of the housing. Thus, when the cleaning device is running and the suction port of the floor brush structure generates suction, the airflow will flow towards the suction port. When the airflow reaches the guide member, the structure formed by the first angle guides the airflow to the side of the suction port, and then into the suction port. Compared to the prior art where the airflow directly enters the suction port, resulting in greater suction at the suction port than on both sides, the floor brush structure provided in this application embodiment can guide a portion of the airflow directly flowing towards the suction port to at least one side of the suction port, thereby relatively reducing the airflow directly flowing towards the suction port and decreasing the suction, while relatively increasing the airflow on at least one side of the suction port and increasing the suction, thus balancing the suction of the floor brush structure.

[0105] The present invention will now be described in detail with reference to the accompanying drawings, so that those skilled in the art can have a clearer and more detailed understanding of the present invention.

[0106] Reference Figures 1 to 16 As shown, this application embodiment provides a floor brush structure, including:

[0107] The housing 100 has a suction port 110.

[0108] The flow guide 200 is located at the front end of the housing 100 in the direction of travel. The flow guide 200 has a flow channel 230. The flow channel 230 and the direction of travel of the housing 100 have a first included angle α. The flow guide 200 covers the suction port 110 and guides the airflow into the suction port 110.

[0109] The bottom of the housing 100 is provided with a placement surface, which faces the surface to be cleaned so as to contact and clean the surface. The suction port 110 is located on the side of the housing 100 facing the placement surface, and the housing 100 has an air duct 120 communicating with the suction port 110. The air duct 120 can be further connected to the suction component of the cleaning device, so that when the suction component is running, suction force is generated at the suction port 110 through the air duct 120 to adsorb dirt and dust on the surface to be cleaned.

[0110] The draining member 200 is disposed on the housing 100, located on the side of the housing 100 facing the placement surface, and along the traveling direction of the housing 100, the draining member 200 is located in front of the suction port 110 to cover the suction port 110.

[0111] A flow channel 230 is provided on the flow guide 200, and the flow channel 230 has a first included angle α (the first included angle α can be 0°) along the traveling direction of the housing 100, so that at least part of the side of the flow guide 200 away from the suction port 110 is inclined relative to the traveling direction of the housing 100. In this way, when the suction port 110 is drawing air, the air in front of the housing 100 gathers towards the suction port 110. Among them, part of the airflow flowing from the front side of the suction port 110 to the suction port 110 is guided by the flow channel on the flow guide 200 to at least one side of the suction port 110 when it reaches the flow guide 200, and further flows to the side of the suction port 110, that is, to the side in the width direction of the housing 100, and further enters the suction port 110 from there.

[0112] Therefore, the floor brush structure housing 100 provided in this embodiment of the application is provided with a suction port 110, and a guide member 200 corresponding to the suction port 110 is provided on the front side along the traveling direction of the housing 100. The guide member 200 covers the suction port 110, and the guide member 200 has a guide channel 230, which has a first included angle α (the first included angle α can be 0°) along the traveling direction of the housing 100. Thus, when the cleaning equipment is running and the suction port 110 of the floor brush structure generates suction, the airflow will flow towards the suction port 110. When the airflow flows to the guide member 200, the guide member 200 guides the airflow to the side of the suction port 110 through the guide channel 230, and then flows into the suction port 110.

[0113] Compared to the prior art where airflow directly enters the suction port 110, resulting in greater suction at the suction port 110 than on both sides of the suction port 110, the floor brush structure provided in this application embodiment can guide part of the airflow that flows directly to the suction port 110 to at least one side of the suction port 110, thereby relatively reducing the airflow that flows directly to the suction port 110 and decreasing the suction, while relatively increasing the airflow on at least one side of the suction port 110 and increasing the suction, so as to balance the suction of the floor brush structure.

[0114] In some embodiments, refer to Figure 1 and Figure 2 As shown, the floor brush structure also includes a dust cup assembly 300, which is disposed on the housing 100 and is connected to the suction port 110 through the air duct 120.

[0115] It is understandable that by placing the dust cup assembly 300 on the floor brush structure, the distance between the dust cup assembly 300 and the suction port 110 can be closer, and the air duct 120 can be shorter, so that dust and dirt can enter the dust cup assembly 300 in time, resulting in better dust collection efficiency.

[0116] Furthermore, refer to Figure 1 and Figure 2 As shown, the dust cup assembly 300 has an air inlet 310, which is connected to the suction port 110 through the air duct 120.

[0117] It is understandable that by setting up the air inlet 310, the dust suction of the cleaning equipment can be made smoother, and dust and dirt can be prevented from entering other parts of the cleaning equipment.

[0118] Furthermore, the air duct 120 is a straight air duct 120, and the air inlet 310 and the suction inlet 110 are located in the extension direction of the air duct 120.

[0119] By setting a straight air duct 120, the bends in the air duct 120 can be reduced, thereby reducing the airflow resistance in the air duct 120, improving the suction efficiency, reducing the amount of dust residue in the air duct 120, and reducing airflow noise.

[0120] In some embodiments, refer to Figure 4 and Figure 5 As shown, the drainage component 200 is provided with a through groove, which forms a drainage channel 230;

[0121] Or, refer to Figure 3 ,and Figures 6 to 8 As shown, the drainage component 200 includes a first drainage rib 210 and a plurality of second drainage ribs 220. The plurality of second drainage ribs 220 are respectively spaced apart on opposite sides of the first drainage rib 210. A drainage channel 230 is formed between two adjacent second drainage ribs 220 and between the first drainage rib 210 and the second drainage rib 220 adjacent to the first drainage rib 210.

[0122] Or, refer to Figures 9 to 16 As shown, the drainage component 200 includes a plurality of second drainage ribs 220, which are arranged sequentially at intervals, and a drainage channel 230 is formed between two adjacent second drainage ribs 220.

[0123] Understandably, this configuration allows the drainage component 200 to form three types of structures with drainage channels 230. The first type is formed by directly opening a through groove on the drainage component 200 itself to form the drainage channel 230. The second type is formed by the first drainage rib 210 and multiple second drainage ribs 220 together, making the structure of the drainage component 200 more flexible and diverse, and its application range wider. The third type is formed by multiple second drainage ribs 220 alone.

[0124] Firstly, it is understandable that directly opening a through groove on the drainage component 200 to form a drainage channel can make the structure of the drainage component 200 simpler and more compact.

[0125] Secondly, multiple second guide ribs 220 are provided on the basis of the first guide rib 210 and distributed on at least one side of the first guide rib 210, so that the first guide rib 210 and the second guide rib 220 are combined, so that the airflow can be guided more efficiently from the front of the suction port 110 to at least one side of the suction port 110, thereby enhancing the suction force on the corresponding side of the suction port 110 and better achieving a balanced distribution of the floor brush suction force.

[0126] Thirdly, similarly, by sequentially and intermittently setting multiple second drainage ribs 220 to form a drainage channel 230, the structure of the drainage component 200 can be made more flexible and diverse by adjusting the structure and setting position of each second drainage rib 220, so as to adapt to different drainage needs.

[0127] It is understood that the number of diversion channels 230 can be controlled between 8 and 16, or less than 8, and this application does not impose any restrictions on this.

[0128] The flow channel 230 provides a clear flow path for the airflow, accurately guiding the surrounding airflow to the suction port 110. During cleaning operation, the airflow flows orderly along the flow channel 230, preventing disordered diffusion and turbulence, allowing the airflow to act more concentratedly on the suction port 110, thus enhancing the suction force at the suction port 110. To ensure a balanced suction effect of the flow guide 200 on the suction port 110, the number of second flow guide ribs 220 on the side of the suction port 110 with lower suction force is typically greater than that on the side with higher suction force, specifically, one to four more.

[0129] With this setup, when cleaning larger solid particles (such as corn, rice, mung beans, etc.) or smaller solid particles (such as millet, gravel, etc.), the solid particles can be sucked into the suction port 110 from both sides of the guide 200. For some tiny particles (such as flour, dust, etc.), the tiny particles can be sucked into the suction port 110 along the guide channel 230, avoiding the accumulation of tiny particles in dead corners where the suction is weak.

[0130] Furthermore, since some airflow can flow directly from the drainage channel 230 to the suction port 110, when the drainage component 200 collides with larger solid particles, the suction force at the drainage channel 230 can have a certain buffering and adsorption effect on the larger solid particles, preventing the larger fixed shell 100 from being knocked away.

[0131] In some embodiments, refer to Figure 15 and Figure 16 As shown, multiple through slots are provided on the second drainage rib 220. The multiple through slots are spaced apart along the extension direction of the second drainage rib 220, and the through slots connect two adjacent drainage channels 230.

[0132] The adjacent two flow channels 230 are connected by through grooves on the second flow ribs 220, allowing the airflow to be guided multiple times through each second flow rib 220 as it passes through them sequentially, forming a continuous and stable guidance path. When the airflow reaches the flow guide 200, the adjacent two flow channels 230 can relay the airflow through the through grooves, allowing the airflow to flow more smoothly from the front end of the flow guide 200 to the side of the suction port 110, reducing airflow loss and turbulence, improving the efficiency of airflow guidance, and thus enhancing the suction force on the corresponding side of the suction port 110, balancing the suction force on the side of the suction port 110 and at the suction port 110 itself.

[0133] The bottom of the through groove on the second drainage rib 220 extends to the shell 100.

[0134] This design allows for greater airflow at the second duct 220, thereby further improving the smoothness of airflow.

[0135] In practice, the first included angle α is greater than or equal to 0° and less than or equal to 50°.

[0136] Thus, by making the first included angle between 0° and 50°, it is possible to... Figure 3 , Figure 4 , Figure 5 , Figure 9 , Figure 10 and Figure 13 As shown, the drainage channel 230 is parallel to the direction of travel of the housing 100, that is, the first included angle α is 0°, or as shown in the figure. Figure 6 , Figure 7 , Figure 8 , Figure 11 , Figure 12 , Figure 14 , Figure 15 and Figure 16 As shown, the flow channel 230 is tilted relative to the direction of travel of the housing 100 to expand the airflow collection range, so that the airflow can flow more fully to at least one side of the suction port 110 under the action of the second flow guide rib 220 and the flow end 221.

[0137] For example, the first included angle α can be 0°, 10°, 20°, 30°, 40° or 50°, and this application does not limit it.

[0138] In some embodiments, refer to Figure Figure 3 ,and Figures 9 to 16 As shown, each drainage channel 230 is parallel to the others;

[0139] Or, refer to Figure 6 , Figure 7 , Figure 8 As shown, the drainage channels 230 located on the same side of the first drainage rib 210 are parallel to each other.

[0140] It should be noted that when the flow channels 230 are parallel to each other, the second flow guide ribs 220 are also parallel to each other. This parallel arrangement of the second flow guide ribs 220 provides a straight guiding path for the airflow. As the equipment moves forward, the airflow can flow smoothly along these guide ribs to the suction port 110, reducing airflow bends and turbulence, thereby reducing energy loss during airflow and improving airflow guidance efficiency.

[0141] When the drainage channels 230 located on the same side of the first drainage rib 210 are parallel to each other, the second drainage rib 220 can be tilted relative to the first drainage rib 210. During the movement of the equipment, the tilted second drainage rib 220 guides the airflow more fully to both sides of the suction port 110, enhances the suction force on both sides of the suction port 110, and facilitates the guidance of dust and debris far away from the suction port 110 to the suction port 110, increasing the effective range of the suction port 110 and improving the cleaning coverage area.

[0142] In some embodiments, each drainage channel 230 is inclined relative to the surface of the housing 100 toward the first drainage rib 210.

[0143] It is understandable that the inclined design further increases the side surface area of ​​the second guide rib 220, allowing for more thorough contact with the airflow and optimizing the airflow path to better guide the airflow to the side of the suction port 110. When the airflow reaches the guide member 200, the second guide rib 220, which is inclined relative to the surface of the housing 100, can more accurately guide the airflow, increase the airflow on both sides of the suction port 110, and thus effectively balance the suction force on both sides of the suction port 110.

[0144] Furthermore, each drainage channel 230 is symmetrically arranged relative to the first drainage rib 210.

[0145] This design allows for a more balanced and consistent distribution of airflow and suction on both sides of the inlet 110.

[0146] In some embodiments, the width of the drainage channel 230 is greater than or equal to 1 mm and less than or equal to 1.6 mm.

[0147] An appropriate width range ensures that the airflow maintains a suitable speed within the drainage channel 230. If the width is too large, the airflow speed will decrease, reducing its ability to carry dust and debris, making it difficult to effectively suck pollutants from the ground into the suction port 110; conversely, if the width is too small, the airflow will encounter greater resistance, which is also detrimental to smooth airflow. With a width of 1mm to 1.6mm, the airflow can pass through the drainage channel 230 at a suitable speed, providing power for efficient dust collection. Furthermore, this width range is typically smaller than larger particles such as corn and mung beans, but larger than tiny particles such as flour, so that larger particles are intercepted and sequentially guided through the drainage end 221 to both sides of the suction port 110, allowing only tiny particles and dust to pass through.

[0148] In this embodiment, the width of the drainage channel 230 can be set to 1.5mm. In other embodiments, the width of the drainage channel 230 can also be set to 1mm, 1.1mm, 1.2mm, 1.3mm, 1.4mm or 1.6mm. This application does not limit this.

[0149] In addition, the width of the corresponding second guide rib can be set to 2mm.

[0150] In some embodiments, the width of the same drainage channel 230 gradually increases from the side away from the suction port 110 to the side facing the suction port 110.

[0151] It is understandable that when gas flows in the variable cross-section drainage channel 230, the flow velocity is slower at the narrower parts of the channel and faster at the wider parts. By gradually increasing the width of the drainage channel 230, the airflow gradually accelerates as it flows towards the suction port 110, thereby more quickly drawing dust and dirt into the suction port 110 and improving the dust collection efficiency of the floor brush structure. For example, within the same flow channel, the maximum width of the drainage channel 230 facing the suction port 110 can be three times the width of that side.

[0152] Furthermore, two drainage channels 230 can be set up, and the width of the drainage channel 230 gradually increases along the first distance decreasing direction of the drainage end 221, so as to further improve the drainage effect of the drainage channel 230.

[0153] In some embodiments, refer to Figure 4 and Figure 5 As shown, the drainage member 200 has a protrusion 240, which has a second included angle β along the traveling direction of the housing 100.

[0154] The protrusion 240 can be a sharp corner on the drainage member 200 itself or a sharp corner on the first drainage rib 210. The second included angle β is greater than or equal to 60° and less than or equal to 110°.

[0155] It is understandable that setting the second included angle β to 60° to 110° allows the airflow to be dispersed to both sides of the suction port 110 at a suitable angle. If the included angle is too small, the airflow will be too concentrated and the dispersion effect will be poor, which may result in the suction increase effect on both sides of the suction port 110 being not obvious. If the included angle is too large, the airflow will be dispersed too much and may be dispersed to the sides of the housing 100 in the width direction, affecting the dust collection effect of the floor brush structure.

[0156] For example, the second included angle β can be set to 60°, 70°, 80°, 90°, 100° or 110°, and this application does not limit it. In this embodiment, the second included angle β is set to 90°, which can make the airflow flow more smoothly and be distributed to the opposite sides of the suction port 110.

[0157] In some embodiments, reference is made to Figure 3 ,and Figures 6 to 16 As shown, each of the second drainage ribs 220 has a drainage end 221, the drainage end 221 is away from the suction port 110, and there is a first distance between each drainage end 221 and the suction port 110;

[0158] Each first distance decreases sequentially toward at least one of the opposite sides of the suction port 110.

[0159] The first distance between the drainage end 221 on the second drainage rib 220 and the suction port 110 is set to decrease sequentially towards at least one side of the suction port 110, as follows: Figure 3 , Figure 6 , Figure 7 and Figure 8 As shown, the first distance between the drainage end 221 and the suction port 110 is made to decrease sequentially towards the opposite sides of the suction port 110, or as shown in the figure. Figures 9 to 16 As shown, the first distance between the guide end 221 and the suction port 110 is gradually reduced to one side of the suction port 110. This allows the airflow to flow from the guide end 221 to the suction port 110 in an orderly gradient, enabling the airflow to converge at the suction port 110 in a layered and orderly manner, avoiding airflow chaos and mutual interference, and improving the airflow guidance efficiency.

[0160] And as Figures 9 to 16 As shown, the first distance between the drainage end 221 and the suction port 110 can decrease sequentially towards the left side of the suction port 110 or towards the right side of the suction port 110. Specifically, it can decrease sequentially towards the side with relatively weak suction force according to the suction force distribution requirements of the suction port 110. This application does not impose any restrictions on this.

[0161] In some embodiments, the first distance is greater than or equal to 31 mm and less than or equal to 60 mm.

[0162] Within a range of 31mm to 60mm, the airflow, guided by the guide end 221, flows towards the suction port 110 at a suitable speed and direction, optimizing the airflow distribution and enhancing the overall suction effect of the suction port 110. If the distance is too close, the guide end 221 may be too close to the suction port 110, making the space for the first guide rib 210 and the second guide rib 220 relatively small. After the airflow passes through the guide end 221, it needs to make a significant adjustment to the angle to enter the suction port 110, which can easily form a vortex at the suction port 110 and fail to effectively expand the suction coverage area. If the distance is too far, the airflow will lose too much energy during its journey to the suction port 110, resulting in insufficient suction around the suction port 110, especially in the edge areas, affecting the balanced distribution of suction.

[0163] In this embodiment, the first distance is set to 40mm. In other embodiments, the first distance may also be set to 31mm, 35mm, 38mm, 39mm, 41mm, 42mm, 48mm, 50mm or 55mm, etc. This application does not limit this.

[0164] In some embodiments, refer to Figure 3 ,as well as Figures 6 to 16 As shown, the drainage end 221 is an inclined surface that faces the suction port 110.

[0165] The sloping design can better match the direction of airflow, so that when the airflow comes into contact with the guide end 221, it can flow smoothly along the sloping surface to the suction port 110.

[0166] Compared to the end face of the vertical housing 100 in the direction of travel, the inclined surface can reduce the collision and reflection of airflow, reduce the loss of airflow energy, and thus guide the airflow to the inlet 110 more efficiently, enhancing the suction force at the inlet 110 and on both sides of the inlet 110.

[0167] The inclined planes are located in the same plane, and the plane and the direction of travel of the shell 100 have a third angle γ.

[0168] This can further improve the smoothness and consistency of airflow along the guide end. For example, the third included angle γ can be greater than or equal to 40° and less than or equal to 50°, and this application does not limit it.

[0169] Furthermore, in some embodiments, the end of the first drainage rib 210 facing the suction port 110 has a second distance from the suction port 110, and the end of each second drainage rib 220 facing the suction port 110 has a third distance from the suction port 110.

[0170] Reference Figure 3 , Figure 7 and Figure 8 As shown, the second distance and each of the third distances are equal;

[0171] Or, refer to Figure 6 As shown, all third distances are equal, and the third distance is less than the second distance.

[0172] Thus, when the ends of the first guide rib 210 and the second guide rib 220 facing the suction port 110 are equidistant from the suction port 110, the path length of the airflow from each guide rib to the suction port 110 depends only on the first distance. This allows the airflow guided by different guide ribs to converge at the suction port 110 along the distribution gradient of the guide end 221 under the guidance of the guide end 221, forming a uniform and stable airflow field at the suction port 110.

[0173] When the second distance of the first guide rib 210 is less than the third distance of each of the second guide ribs 220, the ends of the second guide ribs 220 are closer to the suction port 110, allowing the airflow guided from the second guide ribs 220 to reach the suction port 110 more quickly and directly. This creates a stronger airflow in the edge region of the suction port 110, helping to expand the effective range of the suction port 110, especially for dust and debris at edges and corners, enabling more effective suction.

[0174] In addition, refer to Figures 9 to 12 As shown, each of the second drainage ribs 220 has a third distance between its end facing the suction port 110 and the suction port 110, and all the third distances are equal.

[0175] Alternatively, each third distance decreases sequentially from one side of each second drainage rib 220 to the other side.

[0176] Understandably, when all third distances are equal, the path length of the airflow from each second guide rib 220 to the inlet 110 can also depend on the first distance between the guide end 221 on the second guide rib 220 and the inlet, so that the airflow guided by different second guide ribs 220 can converge to the inlet 110 along the distribution gradient of the guide end 221 under the guidance of the guide end 221, forming a uniform and stable airflow field at the inlet 110.

[0177] When the third distance decreases sequentially from one side of each of the second drainage ribs 220 to the other side, the decreasing direction of the third distance is consistent with the decreasing direction of the first distance. This makes the length of each of the second drainage ribs 220 shorter and the length of the drainage channel 230 shorter, reducing the installation space occupied by the drainage component 200, and allowing the airflow to reach the suction port 110 faster and more directly, forming a stronger suction on the corresponding side of the suction port 110.

[0178] The third distance is greater than or equal to 15mm and less than or equal to 44.5mm.

[0179] As the airflow flows along the second guide rib 220 to the end facing the suction port 110, this distance provides sufficient space for buffering, preventing airflow turbulence or vortex formation due to direct impact on the suction port 110. At the same time, within this space, the airflow can accelerate towards the suction port 110 in a suitable manner, ensuring sufficient speed and power to carry dust and debris into the suction port 110.

[0180] In this embodiment, the third distance can be set to 24.5mm, then the second distance is greater than or equal to 24.5mm and less than the first distance. In other embodiments, the third distance can also be set to 15mm, 18mm, 22.5mm, 23.5mm, 25.5mm, 26.5mm, 28mm, 34mm or 40mm, etc. This application does not limit this.

[0181] In some embodiments, refer to Figure 1 and Figure 2 As shown, the distance between the side of the drainage element 200 away from the housing 100 and the housing 100 is greater than or equal to 0.5 mm and less than or equal to 1.2 mm.

[0182] To a certain extent, this distance range can adapt to different surfaces to be cleaned. When cleaning slightly uneven surfaces, a distance of 0.5mm to 1.2mm can ensure that the drainage component 200 and the surface to be cleaned can still maintain a good gap, and the suction effect will not be affected by the slight undulations of the surface to be cleaned. It can also avoid frequent friction between the drainage component 200 and the surface to be cleaned.

[0183] For example, in this embodiment, the side of the drainage member 200 away from the housing 100 can be set to be parallel to the surface to be cleaned, and the gap between the two is 1±0.1mm, that is, greater than or equal to 0.9mm and less than or equal to 1.1mm. In other embodiments, the distance between the drainage member 200 and the surface to be cleaned can also be set to 0.5mm, 0.6mm, 0.7mm or 0.8mm. This application does not limit this.

[0184] In some embodiments, the drainage element 200 is a drainage soft rubber element.

[0185] The drainage soft rubber component is designed to cushion the impact when the drainage component 200 collides with larger solid particles such as corn, rice, and mung beans, or smaller solid particles such as millet and gravel, preventing the solid particles from being knocked too far away and affecting the convenience and efficiency of cleaning. Furthermore, the protrusions can separate solid particles into two parts, allowing them to flow along the drainage component 200 to both sides of the suction port 110 and be drawn into the suction port 110, resulting in better cleaning performance.

[0186] When the brush structure adsorbs small particles such as flour and dust, it can draw the small particles into the suction port 110 along the direction of airflow, avoiding the accumulation of small particles in dead corners where the suction is weak.

[0187] Furthermore, the Shore hardness of the drainage soft rubber component is greater than or equal to 45A and less than or equal to 85A.

[0188] It is understandable that a hardness of 45A to 85A can ensure that soft rubber parts will not be excessively deformed or damaged when subjected to airflow impact and external pressure, thus maintaining their original shape and function and ensuring the normal operation of the equipment.

[0189] For example, in this embodiment, the Shore hardness of the drainage soft rubber component is 85A. In other embodiments, the Shore hardness of the drainage soft rubber component may also be set to 45A, 55A, 65A or 75A, or other hardness values. This application does not limit this.

[0190] In one possible implementation, the drainage element 200 is integrally formed with the housing 100;

[0191] Alternatively, the housing 100 has a mounting portion, and the drain member 200 is disposed on the mounting portion;

[0192] Alternatively, the drainage component 200 can be bonded to the housing 100.

[0193] Thus, the installation method of the drainage component 200 can be flexibly selected according to the installation requirements of the drainage component 200, ensuring the convenience of installation and use of the drainage component 200.

[0194] The one-piece molding method makes the drainage component 200 and the housing 100 a single structure, with strong integrity and firm connection, ensuring the stability and reliability of the floor brush structure. When the housing 100 has a mounting part and the drainage component 200 is set on the mounting part, the drainage component 200 can be installed and disassembled relatively easily, which is convenient when the drainage component 200 is damaged or needs to be replaced with a different type of drainage component 200. The adhesive method can make the drainage component 200 tightly connected to the housing 100. The adhesive process is relatively simple and the production cost is low.

[0195] Reference Figure 2 As shown, in some embodiments, the suction port 110 is located on one side of the centerline in the direction of travel of the housing 100.

[0196] Since the dust cup assembly 300 is mounted on the housing 100 of the floor brush structure, and the air inlet 310 of the dust cup assembly 300 is located at one end of the dust cup assembly 300, if the suction port 110 is located on the center line of the housing 100, the volume of the dust cup assembly 300 will be limited. Therefore, by placing the suction port 110 on one side of the center line in the direction of travel of the housing 100, more space is provided for the layout of components such as the dust cup assembly 300 on the floor brush structure, making the entire device more compact.

[0197] Reference Figure 2 As shown, in some embodiments, the housing 100 has a receiving groove 130, a suction port 110 is in the receiving groove 130, and a drain member 200 is on the front side of the receiving groove 130 along the traveling direction of the housing 100.

[0198] This configuration creates a more ample negative pressure adsorption space in front of the suction port 110 through the receiving groove 130, thereby increasing the suction range and preventing the suction port 110 from being placed directly on the placement surface, which would result in a smaller suction port area.

[0199] This application also provides a cleaning device, including a cleaning device body and a floor brush structure as described in any of the above embodiments disposed on the cleaning device body.

[0200] The floor brush structure has been described in detail in the above embodiments and will not be repeated here.

[0201] The cleaning device provided in this application embodiment features a floor brush structure. The housing 100 of the floor brush structure has a suction port 110. A guide member 200 corresponding to the suction port 110 is located on the front side of the housing 100 along its traveling direction. The guide member 200 covers the suction port 110 and has a guide channel 230. The guide channel 230 has a first included angle α (which can be 0°) along the traveling direction of the housing 100. Thus, when the cleaning device is running and the suction port 110 of the floor brush structure generates suction, the airflow will flow towards the suction port 110. When the airflow reaches the guide member 200, the guide channel 230 will guide the airflow to the side of the suction port 110, and then allow it to flow into the suction port 110. Compared to the prior art where airflow directly enters the suction port 110, resulting in greater suction at the suction port 110 than on both sides of the suction port 110, the floor brush structure provided in this application embodiment can guide part of the airflow that flows directly to the suction port 110 to at least one side of the suction port 110, thereby relatively reducing the airflow that flows directly to the suction port 110 and decreasing the suction, while relatively increasing the airflow on at least one side of the suction port 110 and increasing the suction, so as to balance the suction of the floor brush structure.
