Abstract
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 draining element has a protrusion on the front side of the housing in the direction of travel, and the projection of the protrusion toward the suction port is located inside the suction port.
[0009] Thus, the floor brush structure has a suction port on its housing, and a guide member corresponding to the suction port is located on the front side of the housing along the direction of travel. The guide member has a protrusion, and the projection of the protrusion toward the suction port is located inside the suction port. Therefore, when the cleaning equipment is running and the suction port of the floor brush structure generates suction, the airflow will flow toward the suction port. When the airflow reaches the guide member, the protrusion on the guide member will disperse the airflow into two parts, and guide it to the side of the suction port through the guide member, and then flow 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 can disperse part of the airflow directly flowing toward the suction port to the side of the suction port, thereby relatively reducing the airflow directly toward the suction port and decreasing the suction, while relatively increasing the airflow on both sides 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 a shorter air duct.
[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 makes the vacuuming operation of the cleaning equipment smoother.
[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 within the duct.
[0016] In one possible implementation, the floor brush structure provided in this application includes a first drainage portion and a second drainage portion, which are connected. A protrusion is formed at the connection between the first drainage portion and the second drainage portion, and the first drainage portion and the second drainage portion extend to opposite sides of the suction port.
[0017] In this way, the protrusion can disperse the airflow to the first and second guide sections, and guide the dispersed airflow to the opposite sides of the suction port through the first and second guide sections respectively, thereby increasing the suction force on the opposite sides of the suction port.
[0018] In one possible implementation, the floor brush structure provided in this application embodiment has the ends of the first drainage portion and the second drainage portion connected to form a protrusion.
[0019] In this way, the protrusion can be made more prominent and regular in shape, and the airflow can be more effectively dispersed into two parts.
[0020] In one possible implementation, the floor brush structure provided in this application embodiment has a protrusion with a first included angle, which is greater than or equal to 60° and less than or equal to 110°.
[0021] In this way, the airflow can be dispersed to both sides of the inlet at a suitable angle.
[0022] In one possible implementation, the length of the end face of the protrusion facing the front end of the housing in the direction of travel of the floor brush structure provided in this application is greater than or equal to 10 mm and less than or equal to 15 mm.
[0023] This allows the protrusion to have sufficient area to disperse the airflow flowing from the front towards the inlet.
[0024] In one possible implementation, the floor brush structure provided in this application embodiment has at least one of the first drainage portion and the second drainage portion being arc-shaped.
[0025] In this way, a smooth guiding path can be provided for the airflow, allowing the airflow to turn more naturally and smoothly when passing through the guide section.
[0026] In one possible implementation, the floor brush structure provided in this application embodiment has an arc-shaped first drainage section and a second drainage section, and the first drainage section and the second drainage section are tangent to each other.
[0027] This results in a more consistent suction effect on both sides of the suction port.
[0028] In one possible implementation, the floor brush structure provided in this application embodiment has a first drainage section and a second drainage section symmetrically arranged.
[0029] This ensures that the airflow from the first and second drainage sections is guided evenly to both sides of the suction port, guaranteeing a uniform suction distribution on both sides of the suction port.
[0030] In one possible implementation, the floor brush structure provided in this application embodiment has at least one drainage groove on the drainage component, and the opening of the drainage groove is away from the housing.
[0031] In this way, some airflow can enter the guide channel and flow along the guide channel to the suction port, further optimizing the suction distribution of the floor brush structure.
[0032] In one possible implementation, the floor brush structure provided in this application embodiment has multiple drainage channels, which are sequentially and spaced apart on the drainage component.
[0033] In this way, multiple spaced-apart diversion channels can further subdivide the airflow, allowing for more precise distribution and guidance of the airflow.
[0034] In one possible implementation, the distance between the bottom of the drainage channel and the housing in the floor brush structure provided in this application embodiment is greater than 0 mm and less than or equal to 1.5 mm.
[0035] Alternatively, the bottom of the drainage channel extends onto the housing.
[0036] In this way, the airflow through the first and second diversion sections can be effectively controlled to enter the diversion groove, so that the airflow is concentrated in the diversion groove.
[0037] In one possible implementation, the floor brush structure provided in this application embodiment includes a first drainage rib, and the end of the first drainage rib facing away from the suction port forms a protrusion.
[0038] This allows for a relatively simple design of the protrusion structure and a more stable connection.
[0039] In one possible implementation, the floor brush structure provided in this application embodiment further includes a plurality of second drainage ribs. The plurality of second drainage ribs are respectively arranged sequentially on at least one side of the first drainage rib. A drainage channel facing the suction port is formed between two adjacent second drainage ribs and between the first drainage rib and the second drainage rib adjacent to the first drainage rib.
[0040] In this way, a flow channel can be formed, which provides a clear flow path for the airflow and can accurately guide the surrounding airflow to the inlet.
[0041] In one possible implementation, the floor brush structure provided in this application embodiment has a second drainage rib with a drainage end facing away from the suction port. Each drainage end located on the same side as the first drainage rib has a first distance between it and the suction port. Each first distance decreases sequentially from the first drainage rib to the second drainage rib.
[0042] In this way, the flow-guiding end is set to form a first distance, and the first distance decreases sequentially from the first flow-guiding rib to the second flow-guiding rib, so that when the airflow flows from the flow-guiding end to the suction port, an orderly gradient guidance is formed.
[0043] 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.
[0044] In this way, the airflow can be guided by the inlet and flow towards the suction port at a suitable speed and direction, giving full play to the function of the inlet channel, optimizing the airflow distribution, and enhancing the overall suction effect of the suction port.
[0045] In one possible implementation, the floor brush structure provided in this application embodiment has a sloping end that is inclined toward the suction port.
[0046] In this way, the sloping design can better match the direction of airflow, allowing the airflow to flow smoothly towards the inlet along the sloping surface when it comes into contact with the inlet.
[0047] In one possible implementation, the floor brush structure provided in this application embodiment has second drainage ribs on both sides of the first drainage rib, and the second drainage ribs are symmetrically arranged relative to the first drainage rib.
[0048] In this way, the symmetrical second drainage ribs can form a uniform airflow guidance on both sides of the first drainage ribs.
[0049] In one possible implementation, the floor brush structure provided in this application embodiment has a first drainage rib and each of the second drainage ribs parallel to the traveling direction of the housing;
[0050] Alternatively, each of the second drainage ribs has a second included angle with the direction of travel of the shell.
[0051] In this way, the guide ribs are parallel to the direction of travel of the shell, which can reduce the turning and turbulence of the airflow. The guide ribs have a second angle with the direction of travel of the shell, which allows the airflow to be guided more fully to both sides of the suction port.
[0052] 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.
[0053] Thus, a suitable width range ensures that the airflow maintains an appropriate speed within the drainage channel.
[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 is equal to the third distance;
[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 greater than or equal to 15mm and less than or equal to 44.5mm.
[0059] This distance range allows the airflow sufficient space to buffer, preventing airflow turbulence or vortex formation caused by direct impact on the intake.
[0060] In one possible implementation, the floor brush structure provided in this application embodiment has the projection of the protrusion toward the housing located inside the housing.
[0061] This avoids unnecessary interference between the protrusion and external objects.
[0062] In one possible implementation, the distance between the side of the drainage element away from the housing and the bottom surface of the housing in the floor brush structure provided in this application is greater than or equal to 0.5 mm and less than or equal to 1.2 mm.
[0063] 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.
[0064] In one possible implementation, the floor brush structure provided in this application embodiment has a drainage soft rubber component.
[0065] This avoids excessive collisions between the drainage components and solid particles, thus improving the cleaning effect.
[0066] 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.
[0067] This ensures that the soft rubber parts will not be excessively deformed or damaged when subjected to airflow impact and external pressure.
[0068] In one possible implementation, the floor brush structure provided in this application embodiment has the drainage component and the housing integrally formed;
[0069] Alternatively, the housing has a mounting section, and the drainage element is disposed on the mounting section;
[0070] Alternatively, the drainage component can be bonded to the housing.
[0071] 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.
[0072] 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.
[0073] 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.
[0074] Secondly, embodiments of this application provide a cleaning device, including a cleaning device body and any of the aforementioned floor brush structures disposed on the cleaning device body.
[0075] 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 has a protrusion, and the projection of the protrusion toward the suction port is located inside the suction port. Thus, when the cleaning device is running and the suction port of the floor brush structure generates suction, the airflow will flow toward the suction port. When the airflow reaches the guide member, the protrusion on the guide member will disperse the airflow into two parts, and guide it to the side of the suction port through the guide member, and then flow 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 disperse part of the airflow directly flowing toward the suction port to the side of the suction port, thereby relatively reducing the airflow directly flowing toward the suction port and decreasing the suction force, while relatively increasing the airflow on both sides of the suction port and increasing the suction force, thus balancing the suction force of the floor brush structure.

[0091] The accompanying drawings illustrate 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 particular embodiments. Detailed Implementation
[0092] 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.
[0093] 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.
[0094] 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.
[0095] To overcome the shortcomings of existing technologies, 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 has a protrusion, and the projection of the protrusion toward the suction port is located inside the suction port. Thus, when the cleaning device is running and the suction port of the floor brush structure generates suction, the airflow will flow toward the suction port. When the airflow reaches the guide member, the protrusion on the guide member will disperse the airflow into two parts, and guide it to the side of the suction port through the guide member, and then flow 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 disperse part of the airflow directly flowing toward the suction port to the side of the suction port, thereby relatively reducing the airflow directly toward the suction port and decreasing the suction, while relatively increasing the airflow on both sides of the suction port and increasing the suction, thus balancing the suction of the floor brush structure.
[0096] 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.
[0097] In some embodiments, refer to Figures 1 to 10 As shown, this application embodiment provides a floor brush structure, including:
[0098] The housing 100 has a suction port 110.
[0099] The drainage member 200 has a protrusion 230 protruding towards the front side of the housing 100 in the direction of travel, and the projection of the protrusion 230 toward the suction port 110 is located inside the suction port 110.
[0100] The bottom of the housing 100 is provided with a placement surface 130, which faces the surface to be cleaned so as to contact and clean the surface. The suction port 110 is provided on the side of the housing 100 facing the placement surface 130, 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 can be generated at the suction port 110 through the air duct 120 to adsorb dirt and dust on the surface to be cleaned.
[0101] The draining member 200 is disposed on the housing 100, located on the side of the housing 100 facing the placement surface 130, and along the traveling direction of the housing 100, the draining member 200 is located in front of the suction port 110.
[0102] A protrusion 230 is provided on the guide member 200. The protrusion 230 protrudes towards the front side of the housing 100 in the direction of travel, and the projection of the protrusion 230 toward the suction port 110 is located inside the suction port 110, that is, the protrusion 230 protrudes away from the suction port 110. In this way, when the suction port 110 is suctioned, the air in front of the housing 100 gathers toward the suction port 110. Among them, part of the airflow flowing from the front side of the suction port 110 toward the suction port 110 is dispersed to the side of the guide member 200 by the protrusion 230 when it reaches the guide member 200. With the guidance of the guide member 200, it 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.
[0103] When the front side of the housing 100 along the direction of travel has an arc-shaped portion, the protrusion 230 can also extend from the flat portion of the housing 100 to the arc-shaped portion of the housing 100 to increase the installation volume of the protrusion 230 and improve the diversion effect of the protrusion 230.
[0104] 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 has a protrusion 230, and the projection of the protrusion 230 toward the suction port 110 is located inside the suction port 110. Thus, when the cleaning equipment is running, when the suction port 110 of the floor brush structure generates suction, the airflow will flow toward the suction port 110. When the airflow flows to the guide member 200, the protrusion 230 on the guide member 200 will disperse the airflow into two parts, and guide them to the side of the suction port 110 through the guide member 200, and then 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 partially disperse the airflow that flows directly to the suction port 110 to the sides 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 both sides of the suction port 110 and increasing the suction, so as to balance the suction of the floor brush structure.
[0105] 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.
[0106] 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.
[0107] 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.
[0108] 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.
[0109] 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.
[0110] 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.
[0111] In some embodiments, refer to Figures 1 to 6As shown, the drainage member 200 includes a first drainage portion 210 and a second drainage portion 220, the first drainage portion 210 and the second drainage portion 220 are connected, a protrusion 230 is formed at the connection between the first drainage portion 210 and the second drainage portion 220, and the first drainage portion 210 and the second drainage portion 220 extend to opposite sides of the suction port 110 respectively.
[0112] It is understandable that by connecting the first guide section 210 and the second guide section 220 to each other, forming a protrusion 230 at the connection point, and extending them to both sides of the suction port 110, the protrusion 230 can disperse the airflow to the first guide section 210 and the second guide section 220, and guide the dispersed airflow to the opposite sides of the suction port 110 through the first guide section 210 and the second guide section 220, thereby increasing the suction force on the opposite sides of the suction port 110.
[0113] The first guide section 210 and the second guide section 220 provide clear guidance for the airflow, enabling the airflow to flow more orderly from both sides of the suction port 110 to the suction port 110, thereby improving the effective utilization rate of the suction force.
[0114] In some embodiments, refer to Figures 3 to 6 The end of the first drainage portion 210 and the end of the second drainage portion 220 are connected to form a protrusion 230.
[0115] Understandably, the protrusion 230 formed by the end connection of the first guide section 210 and the second guide section 220 has a more prominent and regular shape, which can more effectively disperse the airflow into two parts. Compared with the protrusion structure formed by non-end connection, the protrusion 230 formed by end connection has a more obvious effect on blocking and dispersing the airflow, which can make the airflow more evenly dispersed to both sides of the suction port 110, thereby better balancing the suction force at the suction port 110 and on both sides of the suction port 110.
[0116] In specific implementation, the protrusion 230 has a first included angle, which is greater than or equal to 60° and less than or equal to 110°.
[0117] It is understandable that the first included angle of the protrusion 230 is the included angle between the two ends connecting the first guide portion 210 and the second guide portion 220. Setting the first included angle 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 is too concentrated, and the dispersion effect is 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 dispersion is too large, and it may be dispersed to the sides beyond the width direction of the housing 100, affecting the dust collection effect of the floor brush structure.
[0118] For example, the first included angle can be set to 60°, 70°, 80°, 90°, 100° or 110°, and this application does not limit it. In this embodiment, the first included angle is set to 90°, which can make the airflow flow more smoothly and be distributed to the opposite sides of the suction port 110.
[0119] In some embodiments, refer to Figures 3 to 6 As shown, the length of the end face of the protrusion 230 facing the front end of the housing 100 in the direction of travel is greater than or equal to 10 mm and less than or equal to 15 mm.
[0120] Understandably, this configuration equates to setting the protrusion 230 to a size of 10mm to 15mm along its height direction perpendicular to the surface to be cleaned. This size range provides sufficient area for the protrusion 230 to disperse the airflow flowing from the front towards the suction port 110. When the airflow impacts the protrusion 230, it is effectively dispersed into two parts and guided to both sides of the suction port 110 via the first guide portion 210 and the second guide portion 220. If the end face length is too short, the obstruction and dispersion effect of the protrusion 230 on the airflow will be weakened, potentially failing to guide sufficient airflow to both sides of the suction port 110, resulting in a weak suction boost on both sides of the suction port 110 and difficulty in achieving a balanced suction distribution. Conversely, if the end face length is too long, it may rub against the surface to be cleaned, affecting the movement of the floor brush structure.
[0121] Furthermore, in some embodiments, reference is made to... Figures 3 to 6 As shown, at least one of the first drainage portion 210 and the second drainage portion 220 is arc-shaped.
[0122] It's easy to understand that the curved structure provides a smooth guiding path for airflow, allowing it to change direction more naturally and smoothly as it passes through the guide section. Compared to a straight structure, the curved shape reduces abrupt changes and turbulence in airflow, minimizing energy loss during the guiding process. This allows airflow to be guided more efficiently from the front of the intake 110 to both sides, thereby enhancing suction on both sides of the intake 110 and achieving a better, more balanced distribution of suction power from the floor brush.
[0123] For example, the first drainage portion 210 and the second drainage portion 220 can be as follows: Figure 3 and Figure 5 As shown, the convex side of the arc is positioned away from the suction port 110, or as... Figure 4 and Figure 6 As shown, the convex side of the graphic is oriented toward the suction port 110, but this application does not impose any restrictions on this.
[0124] In specific implementation, refer to Figures 3 to 6 As shown, both the first drainage portion 210 and the second drainage portion 220 are arc-shaped, and the first drainage portion 210 and the second drainage portion 220 are tangent to each other.
[0125] Both the first guide section 210 and the second guide section 220 are arc-shaped, which makes the suction force on both sides of the suction port 110 more even. The tangent arc design allows the airflow to transition continuously and smoothly from the protrusion 230 to the first guide section 210 and the second guide section 220 respectively.
[0126] Furthermore, refer to Figures 3 to 6 As shown, the first drainage section 210 and the second drainage section 220 are symmetrically arranged.
[0127] By making the first drainage section 210 and the second drainage section 220 symmetrical along the direction of travel of the housing 100, the airflow of the first drainage section 210 and the second drainage section 220 to both sides of the suction port 110 can be guided evenly and consistently, ensuring that the suction force distribution on both sides of the suction port 110 is uniform.
[0128] Furthermore, in some embodiments, reference is made to Figure 5 and Figure 6 As shown, at least one drainage groove 240 is provided on the drainage component 200, and the opening of the drainage groove 240 is away from the housing 100.
[0129] It is understandable that by opening a groove 240 on the guide member 200 away from the housing 100, the airflow can enter the guide groove 240 when it flows through the first guide part 210 and the second guide part 220, and flow along the direction of the guide groove 240 to the suction port 110, thereby further optimizing the suction distribution of the floor brush structure and making the suction on both sides of the suction port 110 and the entire width direction of the floor brush more balanced.
[0130] The opening of the drainage channel 240 is away from the housing 100, that is, the opening faces the surface to be cleaned, which makes the airflow velocity at the surface to be cleaned greater, further improving the dust collection and cleaning effect.
[0131] Among them, reference Figure 5 and Figure 6 As shown, there are multiple drainage channels 240, which are arranged sequentially and at intervals on the drainage component 200.
[0132] Multiple spaced-apart airflow channels 240 can further subdivide the airflow, allowing for more precise distribution and guidance. Each airflow channel 240 can guide a portion of the airflow to the suction port 110, thereby making the suction force more uniform across all parts of the suction port 110 and improving the consistency of cleaning.
[0133] Furthermore, the distance between the bottom of the drainage channel 240 and the housing 100 is greater than 0 mm and less than or equal to 1.5 mm;
[0134] Alternatively, the bottom of the drainage channel 240 extends onto the housing 100.
[0135] By setting the depth of the diversion channel 240, the airflow through the first diversion section 210 and the second diversion section 220 can be effectively controlled to enter the diversion channel 240, so that the airflow is concentrated in the diversion channel 240, increasing the airflow in the diversion channel 240, enhancing the adsorption force on dust in specific areas, and facilitating flexible control of airflow speed under different cleaning scenarios.
[0136] For example, the distance between the bottom of the drainage channel 240 and the housing 100 can be set to 0.3mm, 0.6mm, 0.9mm, 1.2mm or 1.5mm, and this application does not limit it.
[0137] Furthermore, in some embodiments, reference is made to Figures 7 to 10 As shown, the drainage member 200 includes a first drainage rib 250, and the end of the first drainage rib 250 facing away from the suction port 110 forms a protrusion 230.
[0138] Unlike Figures 3 to 6 The drainage component 200 structure in this embodiment has a protrusion 230 formed at the end of the first drainage rib 250 away from the suction port 110. The structure design is relatively simple and the connection is relatively stable, which ensures the stability and reliability of the drainage component 200.
[0139] Furthermore, referring to Figure 3 and Figure 6 As shown, the drainage component 200 also includes a plurality of second drainage ribs 260, which are respectively arranged sequentially on at least one side of the first drainage rib 250. A drainage channel 270 facing the suction port 110 is formed between two adjacent second drainage ribs 260 and between the first drainage rib 250 and the second drainage rib 260 adjacent to the first drainage rib 250.
[0140] The flow channel 270 provides a clear flow path for the airflow, accurately guiding the surrounding airflow to the suction port 110, similar to the flow grooves 240 on the first and second flow channels 210. During operation, the airflow flows orderly along the flow channel 270, preventing disordered diffusion and turbulence, and concentrating the airflow onto the suction port 110, thus enhancing the suction force at the suction port 110.
[0141] 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), the tiny particles can be sucked into the suction port 110 along the guide channel 270, avoiding the accumulation of tiny particles in dead corners where the suction is weak.
[0142] Furthermore, since some airflow can flow directly from the drainage channel 270 to the suction port 110, when the drainage component 200 collides with larger solid particles, the suction force at the drainage channel 270 can have a certain buffering and adsorption effect on the larger solid particles, preventing the larger fixed shell 100 from being knocked away.
[0143] Furthermore, in some embodiments, each second drainage rib 260 has a drainage end that is away from the suction port 110. Each drainage end located on the same side as the first drainage rib 250 has a first distance between it and the suction port 110. Each first distance decreases sequentially from the first drainage rib 250 to the second drainage rib 260.
[0144] The distance between the first and second guide ribs decreases sequentially from the first guide rib 250 to the second guide rib 260, creating an orderly gradient guidance as the airflow flows from the guide end to the suction port 110. This allows a portion of the airflow to flow sequentially along the guide ends of each second guide rib 260 to both sides of the suction port 110, while another portion flows through the guide channel 270 to the suction port 110. Specifically, the guide ends of the second guide ribs 260 furthest from the first guide rib 250 are closer to the suction port 110, and their guide channels 270 are shorter. Conversely, the guide ends of the second guide ribs 260 closest to the first guide rib 250 are slightly farther from the suction port 110, and their guide channels 270 are longer. Through the cooperation of the first and second guide ribs 250 and 260, the airflow converges at the suction port 110 in a layered and orderly manner, avoiding airflow chaos and mutual interference, and improving airflow guidance efficiency.
[0145] In some embodiments, the first distance is greater than or equal to 31 mm and less than or equal to 60 mm.
[0146] Within a range of 31mm to 60mm, the airflow, guided by the guide end, flows towards the suction port 110 at a suitable speed and direction, fully utilizing the function of the guide channel 270, optimizing airflow distribution, and enhancing the overall suction effect of the suction port 110. If the distance is too close, the guide end may be too close to the suction port 110, making the space for the first guide rib 250 and the second guide rib 260 relatively small. After the airflow passes through the guide end, it needs to make a significant angle adjustment 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.
[0147] 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.
[0148] And in some embodiments, reference is made to Figures 7 to 10 As shown, the drainage end is an inclined surface that faces the suction port 110.
[0149] The sloping design allows it to better match the direction of airflow, enabling the airflow to flow smoothly towards the inlet 110 when it comes into contact with the inlet end.
[0150] 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.
[0151] For example, the drainage end may be tilted 40° to 50° relative to the direction of travel of the housing 100, and this application does not limit this.
[0152] Furthermore, the protrusion 230 on the first drainage rib 250 and the drainage end on the second drainage rib 260 can together form an obtuse-angled triangular structure away from the suction port 110. The range of the obtuse angle can be determined according to the first included angle on the protrusion 230 and the tilt angle of the drainage end. For example, the range of the obtuse angle can be set to be greater than or equal to 60° and less than or equal to 135°. This application does not limit this.
[0153] In some embodiments, the first drainage rib 250 has a second drainage rib 260 on both sides, and the second drainage rib 260 is symmetrically arranged with respect to the first drainage rib 250.
[0154] The symmetrical second guide ribs 260 can create uniform airflow guidance on both sides of the first guide ribs 250. When the airflow flows to the suction port 110 from different directions, the symmetrical guide channels 270 on both sides can guide the airflow to the suction port 110 along the same path, avoiding the situation where the suction force on one side of the suction port 110 is too strong and the suction force on the other side is too weak, making the suction force on both sides of the suction port 110 more balanced, thereby improving the overall dust collection effect.
[0155] In other embodiments, if the suction force on one side of the suction port 110 is less than that on the other side, more second drainage ribs 260 can be provided on the side with lower pressure corresponding to the first drainage rib 250 to increase the suction force on that side and make the overall suction force distribution more balanced.
[0156] In specific implementation, refer to Figures 7 to 10 As shown, the first drainage rib 250 and each of the second drainage ribs 260 are parallel to the travel direction of the shell 100;
[0157] Alternatively, each of the second drainage ribs 260 has a second included angle with the direction of travel of the housing 100.
[0158] When the first guide rib 250 and each of the second guide ribs 260 are parallel to the direction of travel of the housing 100, they can provide a straight guiding path for the airflow. During the forward movement of the equipment, the airflow can flow smoothly along these guide ribs to the suction port 110, reducing the turning and turbulence of the airflow, thereby reducing the energy loss of the airflow during the flow process and improving the efficiency of airflow guidance.
[0159] The second included angle is greater than half of the first included angle and less than the tilt angle of the guide end. Specifically, the value range of the second included angle can be set to be greater than 0° and less than or equal to 50° to expand the airflow collection range. During the movement of the device, the tilted guide ribs guide the airflow more fully to both sides of the suction port 110, enhance the suction force on both sides of the suction port 110, and facilitate the guidance of dust and debris far away from the suction port 110 to the suction port 110, thereby increasing the effective range of the suction port 110 and improving the cleaning coverage area.
[0160] Furthermore, when the first drainage rib 250 and each of the second drainage ribs 260 are parallel to the travel direction of the housing 100, the drainage channel 270 can be parallel to the travel direction of the housing 100. When each of the second drainage ribs 260 has a second angle with the travel direction of the housing 100, the drainage channel 270 can also have a second angle with the travel direction of the housing 100.
[0161] In some embodiments, the width of the drainage channel 270 is greater than or equal to 1 mm and less than or equal to 1.6 mm.
[0162] An appropriate width range ensures that the airflow maintains a suitable speed within the drainage channel 270. 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 270 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 to both sides of the suction port 110 through the drainage end, allowing only tiny particles and dust to pass through.
[0163] In this embodiment, the width of the drainage channel 270 can be set to 1.5mm. In other embodiments, the width of the drainage channel 270 can also be set to 1mm, 1.1mm, 1.2mm, 1.3mm, 1.4mm or 1.6mm. This application does not limit this.
[0164] In addition, the width of the corresponding second guide rib can be set to 2mm.
[0165] Furthermore, in some embodiments, reference is made to Figures 7 to 10 As shown, the end of the first drainage rib 250 facing the suction port 110 has a second distance from the suction port 110, and the end of each second drainage rib 260 facing the suction port 110 has a third distance from the suction port 110.
[0166] The second distance is equal to the third distance;
[0167] Alternatively, all third distances are equal, and the third distance is less than the second distance.
[0168] When the ends of the first guide rib 250 and the second guide rib 260 facing the inlet 110 are equidistant from the inlet 110, the path length of the airflow from each guide rib to the inlet 110 depends only on the first distance. This allows the airflow guided by different guide ribs to converge at the inlet 110 along the distribution gradient at the guide end, forming a uniform and stable airflow field at the inlet 110.
[0169] When the second distance of the first guide rib 250 is less than the third distance of each of the second guide ribs 260, the ends of the second guide ribs 260 are closer to the suction port 110, allowing the airflow guided from the second guide ribs 260 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.
[0170] The third distance is greater than or equal to 15mm and less than or equal to 44.5mm.
[0171] As the airflow flows along the second guide rib 260 to the end, this distance provides sufficient space for buffering, preventing airflow turbulence or vortex formation caused by 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.
[0172] 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.
[0173] In some embodiments, refer to Figure 1 and Figure 2 As shown, the projection of the protrusion 230 toward the housing 100 is located inside the housing 100.
[0174] This design prevents unnecessary interference between the protrusion 230 and external objects. During use, if the protrusion 230 extends beyond the housing 100, it may easily collide with other objects during movement or operation, potentially damaging the protrusion 230 or even affecting the normal operation of the entire device. Placing the projector within the housing 100 provides some protection for the protrusion 230, reducing the risk of damage from external collisions.
[0175] 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 bottom surface of the housing 100 is greater than or equal to 0.5 mm and less than or equal to 1.2 mm.
[0176] 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.
[0177] 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. This application does not limit this.
[0178] In addition, in some embodiments, the drainage element 200 is a drainage soft rubber element.
[0179] The guide piece 200 buffers the impact when it collides with larger solid particles (such as corn, rice, mung beans, etc.) or smaller solid particles (such as millet, gravel, etc.), preventing the solid particles from being knocked too far away and affecting cleaning convenience and efficiency. Furthermore, the protrusion 230 separates the solid particles into two parts, allowing them to flow along the guide piece to both sides of the suction port 110 and be drawn into it, resulting in better cleaning performance.
[0180] When the brush structure adsorbs some small particles (such as flour or dust), it can draw the small particles into the suction port 110 along the direction of airflow, thus preventing the small particles from accumulating in dead corners where the suction is weak.
[0181] Furthermore, the Shore hardness of the drainage soft rubber component is greater than or equal to 45A and less than or equal to 85A.
[0182] 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.
[0183] 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.
[0184] In some embodiments, the drainage element 200 is integrally formed with the housing 100;
[0185] Alternatively, the housing 100 has a mounting portion, and the drain member 200 is disposed on the mounting portion;
[0186] Alternatively, the drainage component 200 can be bonded to the housing 100.
[0187] 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.
[0188] 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.
[0189] 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.
[0190] 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.
[0191] This application also provides a cleaning device, including a cleaning device body and any of the above-mentioned floor brush structures disposed on the cleaning device body.
[0192] The floor brush structure has been described in detail in the above embodiments and will not be repeated here.
[0193] 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 has a protrusion 230, and the projection of the protrusion 230 toward the suction port 110 is located inside the suction port 110. Thus, when the cleaning device is running, and the suction port 110 of the floor brush structure generates suction, the airflow will flow toward the suction port 110. When the airflow reaches the guide member 200, the protrusion 230 on the guide member 200 will disperse the airflow into two parts, which are then guided to the side of the suction port 110 by the guide member 200, and then 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 partially disperse the airflow that flows directly to the suction port 110 to the sides 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 both sides of the suction port 110 and increasing the suction, so as to balance the suction of the floor brush structure.
