Description

Technical Field

[0001] The present application belongs to the technical field of cleaning equipment, and specifically relates to a floor brush assembly, a cleaning equipment and a cleaning system. Background Art

[0002] At present, most cleaning equipment such as floor scrubbers cannot complete pure vacuuming operations, mainly because most floor scrubbers and other cleaning equipment do not have a cyclone structure inside. Therefore, in the pure vacuuming state, dust is easily accumulated on the filter inside the cleaning equipment, causing dust to spray from the air outlet of the motor inside the cleaning equipment. In the related technology, a nozzle is set for the suction pipeline, and water is sprayed toward the dust through the nozzle to achieve the effect of dust-water mixing, thereby collecting dust and reducing dust accumulation on the filter.

[0003] However, since the dust flows quickly in the suction pipe during the dust suction process, the actual mixing effect of the spray water source and the dust is limited, so the problem of dust accumulation on the filter element is still quite serious in actual use. Utility Model Content

[0004] Purpose of the utility model: to provide a floor brush assembly to solve the above-mentioned technical problems; another purpose of the present application is to provide a cleaning device using the above-mentioned floor brush assembly; another purpose of the present application is to provide a cleaning system using the above-mentioned cleaning device.

[0005] Technical solution: A floor brush assembly, comprising:

[0006] Floor brush body;

[0007] A sewage suction pipe is provided on the floor brush body, the sewage suction pipe has a sewage suction port, the sewage suction pipe includes a first pipe, a second pipe and a third pipe connected in sequence, the sewage suction port is provided upstream of the first pipe, the second pipe has a first guide surface and a second guide surface opposite to each other, the first guide surface includes a first guide section and a second guide section, the first guide section is located upstream of the second guide section, the second guide surface includes a third guide section and a fourth guide section, the third guide section is located upstream of the fourth guide section, the first guide section is bent toward the third guide section, and the fourth guide section is bent toward the second guide section;

[0008] at least two guide portions, at least one of which is disposed in the first guide section and extends toward the third guide section to guide the fluid transported in the first tube toward the third guide section, and at least one of which is disposed in the fourth guide section and extends toward the second guide section to guide the fluid transported in the second tube toward the second guide section;

[0009] A first liquid spraying member is disposed on the sewage suction pipe and is used for spraying liquid toward the fluid before the fluid contacts the third flow guide section.

[0010] By adopting the above technical solution, during the use of the floor brush assembly, the suction pipe sucks in dust and other impurities through the suction port, and at the same time, the first spray member can spray liquid towards the impurities. Dust and other impurities can be mixed with the liquid before contacting the third guide section, forming a fluid that passes through the first tube, the second tube and the third tube in sequence. During the movement of impurities such as dust in the second pipe, since the first guide section is bent toward the third guide section, the impurities such as dust will be offset toward the third guide section. Due to the wall-adhering characteristics of the liquid, the fluid can flow in accordance with the pipe wall of the suction pipe. On this basis, at least one guide portion provided in the first guide section is used to guide the impurities such as dust to move toward the third guide section, and when moving from the first guide section to the third guide section, the impurities such as dust and the liquid can fully collide with the third guide section and further mix, thereby improving the mixing effect of impurities such as dust and the liquid. Subsequently, since the fourth guide section is bent toward the second guide section, the fluid that moves in accordance with the third guide section to the fourth guide section will be offset toward the second guide section. On this basis, at least one guide portion provided in the fourth guide section is used to guide the fluid to move toward the second guide section, so that the fluid can fully collide with the second guide section and further mix, thereby facilitating further improving the mixing effect of impurities such as dust and the liquid. Impurities such as dust and the liquid are mixed by hitting the wall multiple times, which is conducive to directly collecting the mixed fluid, reducing the accumulation of impurities such as dust on the filter element, and improving the collection efficiency of impurities such as dust.

[0011] A floor brush assembly, comprising:

[0012] Floor brush body;

[0013] A sewage suction pipe is provided on the floor brush body, the sewage suction pipe has a sewage suction port, the sewage suction pipe includes a first pipe, a second pipe and a third pipe connected in sequence, the sewage suction port is provided upstream of the first pipe, the second pipe has a first guide surface and a second guide surface opposite to each other, the first guide surface includes a first guide section and a second guide section, the first guide section is located upstream of the second guide section; the second guide surface includes a third guide section and a fourth guide section, the third guide section is located upstream of the fourth guide section, the first guide section is bent toward the third guide section, and the fourth guide section is bent toward the second guide section;

[0014] at least two guide portions, at least one of which is disposed in the first guide section and extends toward the third guide section to guide the fluid transported in the first tube toward the third guide section, and at least one of which is disposed in the fourth guide section and extends toward the second guide section to guide the fluid transported in the second tube toward the second guide section;

[0015] a first liquid spraying member, the first liquid spraying member being disposed on the sewage suction pipe, and being used for spraying liquid toward the fluid before the fluid contacts the third flow guide section;

[0016] Wherein, the third guide section is used to guide the fluid to make a turn greater than 90°;

[0017] And / or, the second guide section is used to guide the fluid to make a turn greater than 90°.

[0018] By adopting the above technical solution, during the use of the floor brush assembly, the suction pipe sucks in dust and other impurities from the suction port, and at the same time, the first liquid spraying member can spray liquid toward the impurities, and the dust and other impurities can mix with the liquid before contacting the third guide section, forming a fluid that passes through the first tube, the second tube and the third tube in sequence. During the movement of dust and other impurities in the second tube, since the first guide section bends toward the third guide section, the dust and other impurities will deviate toward the third guide section at this time. Due to the wall-adhering characteristics of the liquid, the fluid can flow along the wall of the suction pipe. On this basis, at least one drainage section provided in the first guide section guides the dust and other impurities to move toward the third guide section, and when moving from the first guide section to the third guide section, the dust and other impurities and the liquid can fully collide with the third guide section and further mix, thereby improving the mixing effect of dust and other impurities and the liquid. In addition, the fluid can make a turn greater than 90° when continuing to move after colliding at the third guide section, thereby ensuring that the fluid has a longer collision stroke in the second tube and improving the mixing effect for the fluid. When the fluid moves and turns at an angle lower than 90° in the third guide section, the fluid is likely to prematurely detach from the tube wall of the second tube, and the mixing effect will be weakened compared to the collision with the wall with a turn greater than 90°. Similarly, since the fourth guide section bends toward the second guide section, the fluid that moves to the fourth guide section in accordance with the third guide section will deviate toward the second guide section. On this basis, at least one guide portion provided in the fourth guide section guides the fluid to move toward the second guide section, so that the fluid can fully collide with the second guide section and further mix, which is conducive to further improving the mixing effect of impurities such as dust and liquid. In addition, the fluid can make a turn greater than 90° after colliding at the second guide section, thereby ensuring that the fluid has a longer collision stroke in the second tube and improving the mixing effect for the fluid. When the fluid moves at a turning angle of less than 90° in the second guide section, the fluid is likely to leave the tube wall of the second tube prematurely, and the mixing effect will be weakened compared to the wall collision with a turn greater than 90°. Dust and other impurities are mixed with liquid through multiple wall collisions, which is conducive to directly collecting the mixed fluid, reducing the accumulation of dust and other impurities on the filter element, and improving the collection efficiency of dust and other impurities.

[0019] A floor brush assembly, comprising:

[0020] Floor brush body;

[0021] A sewage suction pipe is provided on the floor brush body, the sewage suction pipe has a sewage suction port, the sewage suction pipe includes a first pipe, a second pipe and a third pipe connected in sequence, the sewage suction port is provided upstream of the first pipe; the second pipe has a first guide surface and a second guide surface opposite to each other, the first guide surface includes a first guide section and a second guide section, the first guide section is located upstream of the second guide section; the second guide surface includes a third guide section and a fourth guide section, the third guide section is located upstream of the fourth guide section, the first guide section is bent toward the third guide section, and the fourth guide section is bent toward the second guide section;

[0022] a drainage portion, the drainage portion being disposed in the first drainage section and extending toward the third drainage section so as to guide the fluid transported in the first tube toward the third drainage section;

[0023] A first liquid spraying member is provided on the sewage suction pipe and is used for spraying liquid toward the fluid before the fluid contacts the third flow guide section.

[0024] By adopting the above technical solution, during the use of the floor brush assembly, the suction pipe sucks dust and other impurities from the suction port, and at the same time, the first liquid spraying member can spray liquid toward the impurities, and the dust and other impurities can mix with the liquid before contacting the third guide section, forming a fluid that passes through the first tube, the second tube and the third tube in sequence. During the movement of dust and other impurities in the second tube, since the first guide section bends toward the third guide section, the dust and other impurities will deviate toward the third guide section at this time. Due to the wall-adhering characteristics of the liquid, the fluid can flow along the wall of the suction pipe. On this basis, at least one guide portion provided in the first guide section guides the dust and other impurities to move toward the third guide section, and when moving from the first guide section to the third guide section, the dust and other impurities and the liquid can fully collide with the third guide section and further mix, thereby improving the mixing effect of dust and other impurities and the liquid, which is conducive to directly collecting the mixed fluid, reducing the accumulation of dust and other impurities on the filter element, and improving the collection efficiency of dust and other impurities.

[0025] In some embodiments, at least two of the drainage portions include a first drainage portion and a second drainage portion, and the first drainage portion and the second drainage portion are distributed along the height direction of the floor brush body;

[0026] The first drainage portion has a first end and a second end oppositely disposed in the height direction of the floor brush body, the first end is connected to the first drainage section, the second end faces the third drainage section, and the second drainage portion has a third end and a fourth end oppositely disposed in the height direction of the floor brush body, the third end is connected to the fourth drainage section, and the fourth end faces the second drainage section;

[0027] In the height direction of the floor brush body, the fourth end is lower than the first end.

[0028] By adopting the above technical solution, during the use of the floor brush assembly, the suction pipe sucks in dust and other impurities through the suction port, and at the same time, the first liquid spraying part can spray liquid toward the impurities, and dust and other impurities can be mixed with the liquid before contacting the third guide section, forming a fluid that passes through the first tube, the second tube and the third tube in sequence. The first drainage part guides the fluid to move toward the third guide section so that the fluid hits the third guide section and is further mixed. Subsequently, the fluid moving along the third guide section can be offset toward the second guide section in the fourth guide section, and the second drainage part guides the fluid to move toward the second guide section so that the fluid hits the second guide section and is further mixed. At this time, setting the fourth end lower than the first end in the height direction of the floor brush body, compared with setting the fourth end higher than the first end in the height direction of the floor brush body, can ensure that the fluid has a longer wall-adhering movement distance when moving from the first drainage part to the second drainage part, reduce the problem of the fluid directly crossing the second drainage part after leaving the first drainage part without being guided and hitting the wall, improve the mixing effect of impurities such as dust and liquid, which is conducive to directly collecting the mixed fluid, reduce the accumulation of impurities such as dust in the filter element, and improve the collection efficiency of impurities such as dust.

[0029] In some embodiments, the minimum distance between the second end and the third guide section is a, and the minimum distance between the first end and the third guide section is b, satisfying: ba≥1 / 3b.

[0030] By adopting the above technical scheme, it is ensured that the travel distance of the first guide part to guide the fluid occupies at least one third or more of the distance between the first guide surface and the second guide surface at the position of the first guide part, which is conducive to ensuring that the first guide part can provide better guidance for the fluid and deflect the guiding travel toward the third guide section, thereby improving the effect of high-speed displacement and wall collision of the fluid at the first guide part. When the travel distance of the first guide part to guide the fluid occupies one third or less of the distance between the first guide surface and the second guide surface at the position of the first guide part, it is easy to increase the risk that the fluid does not fully deflect, does not reach and collide with the third guide section, and continues to be transported along the second pipe to the third pipe, which relatively reduces the fluid mixing effect and affects the collection efficiency of impurities such as dust.

[0031] In some embodiments, a≥20 mm is satisfied.

[0032] By adopting the above technical solution, when the sewage suction pipe absorbs dust and other impurities, in addition to dust with smaller particles, there are also impurities with larger particles, ensuring that the minimum distance between the second end and the third guide section is greater than 20 mm, which is conducive to reducing the problem of impurities with a size greater than 20 mm being stuck between the first drainage part and the sewage suction pipe wall, causing impurities to block the sewage suction pipe.

[0033] In some embodiments, the minimum distance between the fourth end and the second guide section is c, and the minimum distance between the third end and the second guide section is d, satisfying: dc≥1 / 3d.

[0034] By adopting the above technical scheme, it is ensured that the stroke of the second guide part to guide the fluid occupies at least one third or more of the distance between the first guide surface and the second guide surface at the position of the second guide part, which is conducive to ensuring that the second guide part can provide better guidance for the fluid and deflect the guiding stroke toward the second guide section, thereby improving the effect of high-speed displacement and wall collision of the fluid at the second guide part. When the stroke of the second guide part to guide the fluid occupies one third or less of the distance between the first guide surface and the second guide surface at the position of the second guide part, it is easy to increase the risk that the fluid does not fully deflect, does not reach and collide with the second guide section, and continues to be transported along the second pipe to the third pipe, which relatively reduces the fluid mixing effect and affects the collection efficiency of impurities such as dust.

[0035] In some embodiments, c≥20 mm.

[0036] By adopting the above technical solution, when the sewage suction pipe absorbs dust and other impurities, in addition to dust with smaller particles, there are also impurities with larger particles, ensuring that the minimum distance between the fourth end and the second guide section is greater than 20 mm, which is beneficial to reducing the problem of impurities with a size greater than 20 mm being stuck between the second drainage section and the sewage suction pipe wall, causing impurities to block the sewage suction pipe.

[0037] In some embodiments, an extension direction of the first guide portion away from the third guide segment and an extension direction of the second guide portion away from the fourth guide segment form an angle α, which satisfies: α≤90°.

[0038] By adopting the above technical solution, the angle formed by the extension direction of the first guide part away from the third guide section and the extension direction of the second guide part away from the fourth guide section is set within 90°, so that the fluid flowing from the first guide part to the second guide part can actually make a turn greater than 90°, which is beneficial to ensure that the fluid flowing against the wall has a sufficient wall-impacting stroke, thereby improving the mixing effect of impurities such as dust and liquid, and is beneficial to directly collect the mixed fluid, reduce the accumulation of impurities such as dust on the filter element, and improve the collection efficiency of impurities such as dust.

[0039] In some embodiments, the first guide portion has a first guide surface, and the first guide surface is tangent to the first guide segment;

[0040] And / or, the second guide portion has a second guide surface, and the second guide surface is tangent to the fourth guide section.

[0041] By adopting the above technical solution, when the fluid flows from the first guide section to the first guide surface, the tangent first guide surface and the first guide section ensure smooth flow of the fluid. In the process of the fluid flowing to the first guide surface, the first guide surface reduces the flow resistance effect of the fluid flowing along the first guide section, which is conducive to reducing the reduction of the fluid flow rate, and is conducive to the fluid having a good high-speed deviation effect along the first guide surface, and improving the mixing effect of the subsequent fluid impacting the tube wall. Similarly, when the fluid flows from the fourth guide section to the second guide surface, the tangent second guide surface and the fourth guide section ensure smooth flow of the fluid. In the process of the fluid flowing to the second guide surface, the second guide surface reduces the flow resistance effect of the fluid flowing along the fourth guide section, which is conducive to reducing the reduction of the fluid flow rate, and is conducive to the fluid having a good high-speed deviation effect along the second guide surface, and improving the mixing effect of the subsequent fluid impacting the tube wall.

[0042] In some embodiments, the maximum width of the first tube is D 1 , the maximum width of the second tube is D 2 , the maximum width of the third tube is D 3 , satisfied: D 2 ≥1.2D 1 ;

[0043] And / or, meet: D 2 ≥1.2D 3 .

[0044] By adopting the above technical solution, the maximum width of the second tube is set to be at least 1.2 times greater than the maximum width of the first tube and / or the third tube, which is beneficial to provide sufficient extension and adjustment space for the drainage structure, ensure the high-speed deviation effect of the fluid in the second tube, avoid the drainage structure causing the internal flow area of ​​the second tube to be too low, and improve the flow capacity of the second tube.

[0045] In some embodiments, the maximum width of the first tube is D 1 , the maximum width of the third tube is D 3 , meet: 28mm ≥ D 1 ≥22mm;

[0046] And / or, meet: 28mm≥D 3 ≥22mm.

[0047] By adopting the above technical solution, the maximum width of the first tube and / or the third tube is set between 22mm and 28mm to meet the flow capacity of the suction pipe to suck and output fluid, ensure that the suction pipe can provide good suction force and suction efficiency, and facilitate cleaning and maintenance. When the maximum width of the first tube and / or the third tube is less than 22mm, on the one hand, some impurities with larger sizes cannot be smoothly sucked into the suction pipe, limiting the suction capacity of the suction pipe, and on the other hand, it is not convenient to clean the impurities accumulated in the suction pipe. When the maximum width of the first tube and / or the third tube is greater than 28mm, on the one hand, it is easy to reduce the suction force and suction effect of the suction pipe, and on the other hand, it also increases the size of the overall equipment, increases the occupied space and the overall quality of use, and is not convenient for storage and use.

[0048] In some embodiments, the floor brush assembly further includes:

[0049] The second liquid spraying member is arranged on the first tube and located upstream of the first liquid spraying member, and the second liquid spraying member is used for spraying liquid toward the fluid.

[0050] By adopting the above technical solution, by adding a second spray component upstream of the first spray component, it is beneficial to further pre-spray liquid on impurities such as dust sucked up by the suction pipe, thereby further improving the mixing effect of dust and other impurities mixed with liquid to form a fluid, which is beneficial to directly collect the mixed fluid, reduce the accumulation of dust and other impurities in the filter element, and improve the collection efficiency of dust and other impurities.

[0051] Correspondingly, a cleaning device described in an embodiment of the present application includes the above-mentioned floor brush assembly.

[0052] By adopting the above technical solution, when the cleaning equipment is used, the floor brush assembly of the cleaning equipment sucks in impurities such as dust through the suction port of the suction pipe. At the same time, the first spray component can spray liquid toward the impurities. Dust and other impurities can be mixed with the liquid before they contact the third guide section. The mixed fluid is successively offset toward the third guide section and toward the second guide section, thereby completing multiple wall-impacting mixing effects. The fluid is guided by the drainage part to further fully hit the wall to further improve the mixing effect of dust and other impurities and liquid, which is conducive to directly collecting the mixed fluid, reducing the accumulation of dust and other impurities in the filter element, and improving the collection efficiency of dust and other impurities.

[0053] In some embodiments, the cleaning device further comprises a cleaning liquid tank;

[0054] The floor brush assembly further includes a liquid pump, which is configured to pump the liquid in the clean liquid tank and deliver it to the first liquid spraying member.

[0055] By adopting the above technical solution, when using the cleaning equipment, the liquid used for cleaning is stored in the clean liquid tank in advance, and the liquid pump directly draws the liquid in the cleaning liquid for the first spray component to spray toward impurities such as dust. There is no need to add an additional liquid supply structure to the first spray component, which reduces the impact on the volume of the cleaning equipment itself, facilitates unified replenishment of the liquid source, and reduces the need for liquid replenishment operations.

[0056] In some embodiments, the floor brush assembly also includes a roller brush and a water diverter for spraying liquid toward the roller brush, the roller brush and the water diverter are respectively arranged on the floor brush body, and the liquid pump is configured to pump the liquid in the clear liquid tank and transport it to the water diverter.

[0057] By adopting the above technical solution, the water dividing component and the first liquid spray component can share a liquid pump. When the cleaning device wet-cleans the surface to be cleaned, the liquid pump can pump the liquid source to the water dividing component and transport it toward the roller brush, thereby wetting the roller brush and performing wet cleaning. When the cleaning device only needs to perform vacuuming operations, the liquid source can be transported only to the first liquid spray component by controlling the liquid pump. There is no need to additionally add a liquid supply structure to supply the first liquid spray component, thereby reducing the impact on the volume of the cleaning device itself, facilitating unified replenishment of the liquid source, and reducing the need for liquid replenishment operations.

[0058] Correspondingly, a cleaning system described in an embodiment of the present application includes the above-mentioned cleaning device and also includes a base station or a charging stand compatible with the cleaning device.

[0059] By adopting the above technical solution, when using a base station compatible with the cleaning equipment, the base station can provide the cleaning equipment with functions such as liquid supply, liquid drainage, self-cleaning, drying and charging, and when using a charging stand, the charging stand can provide the cleaning equipment with functions such as charging, self-cleaning and drying.

[0060] Beneficial effect: During the use of the floor brush assembly of the embodiment of the present application, the suction pipe sucks dust and other impurities from the suction port, and at the same time, the first liquid spraying member can spray liquid toward the impurities, and the dust and other impurities can mix with the liquid before contacting the third guide section, forming a fluid that passes through the first pipe, the second pipe and the third pipe in sequence. During the movement of dust and other impurities in the second pipe, the dust and other impurities will be offset toward the third guide section and the second guide section in sequence. Due to the wall-adhesive property of the liquid, the fluid can flow along the pipe wall of the suction pipe. On this basis, at least one drainage part provided in the first guide section guides the dust and other impurities to move toward the third guide section, and the dust and other impurities and the liquid can fully hit the third guide section and further mix. At least one drainage part provided in the fourth guide section guides the fluid to move toward the second guide section, and the dust and other impurities and the liquid can fully hit the second guide section and further mix, which is conducive to further improving the mixing effect of dust and other impurities and liquid. The dust and other impurities and the liquid are mixed by hitting the wall multiple times, which is conducive to directly collecting the mixed fluid, reducing the accumulation of dust and other impurities on the filter element, and improving the collection efficiency of dust and other impurities.

[0072] The technical solutions in the embodiments of the present application will be described clearly and completely below in conjunction with the drawings in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, rather than all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by those skilled in the art without creative work are within the scope of protection of the present application.

[0073] In the description of the present application, it should be understood that the terms "length", "width", "thickness", "up", "down", "front", "back", "left", "right", "top", "bottom", "inside", "outside" and the like indicate positions or positional relationships based on the positions or positional relationships shown in the accompanying drawings, and are only for the convenience of describing the present application and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore cannot be understood as a limitation on the present application. In addition, the terms "first" and "second" are used for descriptive purposes only, and cannot be understood as indicating or implying relative importance or implicitly indicating the number of technical features indicated. Thus, the features defined as "first" and "second" may explicitly or implicitly include one or more features. In the description of the present application, "multiple" means two or more, and at least one means one, two or more, unless otherwise clearly and specifically defined.

[0074] At present, since there is no separate cyclone structure inside cleaning equipment such as floor scrubbers, most of the cleaning equipment such as floor scrubbers are unable to complete pure vacuuming operations, that is, pure vacuuming operations easily cause a large amount of dust to accumulate in the filter HEPA, causing dust to spray from the air outlet of the suction motor, and other problems.

[0075] Even if a liquid nozzle is installed on the sewage suction pipeline and water is sprayed toward the dust through the nozzle, the dust flows quickly in the pipeline under the suction state, and the actual mixing effect of the sprayed water and the dust is limited. Most of the dust is not fully mixed with the liquid and is transported to the HEPA, causing a large amount of accumulation. At this time, the effect of the nozzle is very limited, and cleaning equipment such as floor scrubbers cannot successfully complete operations such as vacuuming the floor and cleaning the carpet.

[0076] In view of this, combined with Figures 1 to 8 , an embodiment of the present application provides a floor brush assembly, aiming to overcome at least one of the above-mentioned technical problems.

[0077] In the following embodiments, a height direction X is introduced, which is parallel to the overall height direction of the floor brush assembly in this embodiment when used on the surface to be cleaned. Taking a roughly flat floor as a reference for the surface to be cleaned, the height direction X is roughly perpendicular to the surface to be cleaned.

[0078] Reference Figures 1 to 5 A floor brush assembly includes a floor brush body 1, a roller brush 7, a water distribution component 8, a sewage suction pipe 2, at least two drainage parts 3 and a first liquid spray component 4.

[0079] It can be understood that the floor brush assembly can move along a predetermined path to clean the surface to be cleaned, and the surface to be cleaned can be a floor, a carpet, etc.

[0080] The floor brush body 1 is provided with an arrangement cavity 10 for sequentially installing the roller brush 7, the water distribution member 8 and the sewage suction pipe 2. The sewage suction pipe 2 has a sewage suction port 20 facing the roller brush 7. The sewage suction pipe 2 includes a first pipe 21, a second pipe 22 and a third pipe 23 which are sequentially connected. The sewage suction port 20 is arranged upstream of the first pipe 21. The second pipe 22 has a first guide surface 220 and a second guide surface 221 which are opposite to each other. The first guide surface 220 includes a first guide section 2200 and a second guide section 2201. The first guide section 2200 is located upstream of the second guide section 2201. The second guide surface 221 includes a third guide section 2210 and a fourth guide section 2211. The third guide section 2210 is located upstream of the fourth guide section 2211. The first guide section 2200 is bent toward the third guide section 2210, and the fourth guide section 2211 is bent toward the second guide section 2201.

[0081] It should be noted that, in this embodiment, two drainage portions 3 are taken as an example, that is, at least two drainage portions 3 include a first drainage portion 30 and a second drainage portion 31. The first drainage portion 30 is arranged in the first guide section 2200 and extends toward the third guide section 2210 to guide the fluid transported in the first tube 21 toward the third guide section 2210. The drainage portion 3 is arranged in the fourth guide section 2211 and extends toward the second guide section 2201 to guide the fluid transported in the second tube 22 toward the second guide section 2201.

[0082] In other embodiments, the number of drainage parts 3 can be flexibly increased according to the bending structure of the sewage suction pipe 2. For example, in the present embodiment, the actual bending of the sewage suction pipe 2 is approximately an S-shaped structure, and two drainage parts 3 are set corresponding to the two bending areas. It can be understood that in other embodiments, when the sewage suction pipe 2 is provided with more bending areas, the corresponding number of drainage parts 3 can be increased to form a function of guiding the fluid in each bending area.

[0083] The first liquid spraying member 4 is arranged in the sewage suction pipe 2. In this embodiment, the first liquid spraying member 4 is actually arranged in the first tube 21 and is adjacent to the second tube 22, and the liquid spraying end of the first liquid spraying member 4 is arranged toward the first drainage portion 30. The first liquid spraying member 4 can spray liquid toward the fluid before the fluid contacts the third guide section 2210.

[0084] In this embodiment, the pure vacuuming operation of the floor brush assembly is taken as an example. During the use of the floor brush assembly, the suction pipe 2 sucks in dust and other impurities through the suction port 20. At the same time, the first spray member 4 can spray liquid toward the impurities. Dust and other impurities can be mixed with the liquid before contacting the third guide section 2210, forming a fluid that passes through the first tube 21, the second tube 22 and the third tube 23 in sequence. When dust and other impurities move in the second pipe 22, since the first guide section 2200 is bent toward the third guide section 2210, dust and other impurities will be deviated toward the third guide section 2210. Due to the wall-adhering property of the liquid, the fluid can flow along the wall of the sewage suction pipe 2. On this basis, dust and other impurities are guided to move toward the third guide section 2210 through at least one guide portion 3 provided on the first guide section 2200. When moving from the first guide section 2200 to the third guide section 2210, dust and other impurities and liquid can fully collide with the third guide section 2210 and further mix, thereby improving the mixing effect of dust and other impurities and liquid. Subsequently, due to The fourth guide section 2211 bends toward the second guide section 2201, and the fluid that moves from the third guide section 2210 to the fourth guide section 2211 will be offset toward the second guide section 2201. On this basis, at least one guide portion 3 provided on the fourth guide section 2211 guides the fluid to move toward the second guide section 2201, so that the fluid can fully impact the second guide section 2201 and further mix, which is beneficial to further improve the mixing effect of impurities such as dust and liquid. Dust and other impurities are mixed with liquid through multiple wall collisions, which is beneficial to directly collect the mixed fluid, reduce the accumulation of dust and other impurities in the filter element, and improve the collection efficiency of dust and other impurities.

[0085] It should be noted that, in the present embodiment, the first drainage portion 30 and the second drainage portion 31 are actually formed integrally with the sewage suction pipe 2, that is, the first drainage portion 30 and the second drainage portion 31 do not need to be installed in the sewage suction hook as additional structural parts, and the first drainage portion 30 and the second drainage portion 31 can be formed during the molding and manufacturing process of the sewage suction pipe 2, which is beneficial to reduce the installation of structural parts, simplify the manufacturing process of the sewage suction pipe 2 and the drainage portion 3, and improve the installation accuracy of the drainage portion 3 compared to the separate installation of each drainage portion 3.

[0086] In some embodiments, reference Figure 2 and Figure 5 , the first drainage portion 30 and the second drainage portion 31 are distributed along the height direction X of the floor brush body 1. The first drainage portion 30 has a first end 300 and a second end 301 arranged opposite to each other in the height direction X of the floor brush body 1, the first end 300 is connected to the first diversion section 2200, and the second end 301 faces the third diversion section 2210. The second drainage portion 31 has a third end 310 and a fourth end 311 arranged opposite to each other in the height direction X of the floor brush body 1, the third end 310 is connected to the fourth diversion section 2211, and the fourth end 311 faces the second diversion section 2201. In the height direction X of the floor brush body 1, the fourth end 311 is lower than the first end 300.

[0087] It can be understood that when the sewage suction pipe 2 absorbs the mixed liquid with dust and other impurities and moves along the first drainage part 30, the first drainage part 30 guides the fluid to deflect and collide with the third drainage section 2210, and then the fluid moving along the third drainage section 2210 can deflect and collide with the fluid in the fourth drainage section 2211 toward the second drainage section 2201, and at this time, the second drainage section 31 guides the fluid to move toward the second drainage section 2201. Compared with the fourth end 311 being set higher than the first end 300 in the height direction X of the floor brush body 1, the fourth end 311 is set lower than the first end 300 in the height direction X of the floor brush body 1, which can ensure that the fluid moves from the first drainage section 30 to the second drainage section 31. The wall-adhering movement stroke is longer, reducing the problem that the fluid directly crosses the second drainage section 31 after leaving the first drainage section 30 without being guided and hit against the wall, improving the mixing effect of impurities such as dust and liquid, and facilitating the direct collection of mixed fluids, reducing the accumulation of impurities such as dust on the filter element, and improving the collection efficiency of impurities such as dust.

[0088] In some embodiments, reference Figure 3 The sewage suction pipe 2 is formed into a curved S-shaped structure, and the third flow guide section 2210 can guide the fluid to turn more than 90 degrees. Figure 3 As shown in FIG. 1 , taking the flow of a fluid as an example, the fluid is guided upward and deflected by the first guide portion 30 , and the fluid collides with the third guide section 2210 and turns downward along the third guide section 2210 . Figure 3The turning angle γ shown in the figure represents the flow turning angle of the example fluid at that location.

[0089] It is understandable that the guiding and steering function of the third guide section 2210 is available when the sewage suction pipe 2 is formed, and its bending curvature characteristics are used to ensure that the fluid has a longer collision stroke in the second pipe 22, thereby improving the mixing effect on the fluid. It is understandable that when the fluid moves and turns at an angle lower than 90° in the third guide section 2210, the fluid is likely to prematurely detach from the wall of the second pipe 22, and the mixing effect of the collision with the wall will be weakened compared to the turning angle greater than 90°.

[0090] In some embodiments, reference Figure 3 , the second guide section 2201 can guide the fluid to make a turn greater than 90°. Figure 3 As shown in FIG. 1 , taking the flow of a fluid as an example, the fluid is guided downward by the second guide portion 31 and deflected. After the fluid collides with the second guide section 2201, it turns upward along the second guide section 2201. Figure 3 The turning angle β shown in the figure represents the flow turning angle of the example fluid at that location.

[0091] Similarly, it is understandable that the guiding and steering function of the second guide section 2201 is available when the sewage suction pipe 2 is formed, and its bending curvature characteristics are used to ensure that the fluid has a longer collision stroke in the second pipe 22, thereby improving the mixing effect on the fluid. It is understandable that when the fluid moves and turns at an angle lower than 90° in the second guide section 2201, the fluid is likely to prematurely detach from the wall of the second pipe 22, and the mixing effect of the collision with the wall will be weakened compared to the turning angle greater than 90°.

[0092] In some embodiments, reference Figure 4 , the minimum distance between the second end 301 and the third guide section 2210 is a, and the minimum distance between the first end 300 and the third guide section 2210 is b, satisfying: ba≥1 / 3b.

[0093] It should be noted that in this embodiment, the actual flow cross section of the sewage suction pipe 2 is roughly circular, and the diameter changes only at the first pipe 21, the second pipe 22 and the third pipe 23. Therefore, at this time, it is limited to the minimum distance between the second end 301 and the third guide section 2210 on the reference line where the flow cross section diameter of the sewage suction pipe 2 is located.

[0094] Ensuring that the travel distance of the first guide portion 30 to guide the fluid occupies at least one third or more of the distance between the first guide surface 220 and the second guide surface 221 at the position of the first guide portion 30 is conducive to ensuring that the first guide portion 30 can provide better guidance for the fluid and deflect the guiding travel toward the third guide section 2210, thereby improving the effect of high-speed displacement and wall collision of the fluid at the first guide portion 30. When the travel distance of the first guide portion 30 to guide the fluid occupies one third or less of the distance between the first guide surface 220 and the second guide surface 221 at the position of the first guide portion 30, it is easy to increase the risk that the fluid does not fully deflect, does not reach and collide with the third guide section 2210, and continues to be transported along the second pipe 22 to the third pipe 23, which relatively reduces the fluid mixing effect and affects the collection efficiency of impurities such as dust.

[0095] In addition, in some embodiments, reference Figure 4 , satisfying: a≥20mm.

[0096] It can be understood that when the sewage suction pipe 2 absorbs impurities such as dust, in addition to dust with smaller particles, there are also impurities with larger particles. Ensuring that the minimum distance between the second end 301 and the third guide section 2210 is greater than 20 mm is helpful to reduce the problem of impurities with a size greater than 20 mm being stuck between the first drainage section 30 and the wall of the sewage suction pipe 2, causing impurities to block the sewage suction pipe 2.

[0097] Likewise, in some embodiments, reference Figure 4 , the minimum distance between the fourth end 311 and the second guide section 2201 is c, and the minimum distance between the third end 310 and the second guide section 2201 is d, satisfying: dc≥1 / 3d.

[0098] It should be noted that in this embodiment, the actual flow cross section of the sewage suction pipe 2 is roughly circular, and the diameter changes only at the first pipe 21, the second pipe 22 and the third pipe 23. Therefore, at this time, it is limited to the minimum distance between the fourth end 311 and the second guide section 2201 on the reference line where the flow cross section diameter of the sewage suction pipe 2 is located.

[0099] While ensuring that the travel distance of the fluid guided by the second guide portion 31 occupies at least one third or more of the distance between the first guide surface 220 and the second guide surface 221 at the position of the second guide portion 31, it is beneficial to ensure that the second guide portion 31 can provide better guidance for the fluid and deflect the guiding travel toward the second guide section 2201, thereby improving the effect of high-speed displacement and wall collision of the fluid at the second guide portion 31. When the travel distance of the fluid guided by the second guide portion 31 occupies one third or less of the distance between the first guide surface 220 and the second guide surface 221 at the position of the second guide portion 31, it is easy to increase the risk that the fluid does not fully deflect, does not reach and collide with the second guide section 2201, and continues to be transported along the second tube 22 to the third tube 23, which relatively reduces the fluid mixing effect and affects the collection efficiency of impurities such as dust.

[0100] In addition, in some embodiments, reference Figure 4 , satisfying: c ≥ 20mm.

[0101] When the sewage suction pipe 2 absorbs dust and other impurities, in addition to dust with smaller particles, there are also impurities with larger particles. Ensuring that the minimum distance between the fourth end 311 and the second guide section 2201 is greater than 20 mm is helpful to reduce the problem of impurities with a size greater than 20 mm being stuck between the second drainage section 31 and the wall of the sewage suction pipe 2, causing impurities to block the sewage suction pipe 2.

[0102] In addition, in some embodiments, reference Figure 5 An angle α is formed between an extension direction of the first guide portion 30 away from the third guide segment 2210 and an extension direction of the second guide portion 31 away from the fourth guide segment 2211 , satisfying: α≤90°.

[0103] The angle formed by the extension direction of the first drainage part 30 away from the third guide section 2210 and the extension direction of the second drainage part 31 away from the fourth guide section 2211 is set within 90°, so that the fluid flowing from the first drainage part 30 to the second drainage part 31 can actually make a turn greater than 90°, which is conducive to ensuring that the fluid flowing against the wall has a sufficient wall collision stroke, thereby improving the mixing effect of impurities such as dust and liquid, and is conducive to directly collecting the mixed fluid, reducing the accumulation of impurities such as dust on the filter element, and improving the collection efficiency of impurities such as dust. It can be understood that this design structure actually cooperates with the molded bending structure of the sewage suction pipe 2, aiming to direct the fluid to the concave area of ​​the bent inner wall of the sewage suction pipe 2 in turn, so that the fluid can turn and collide along the pipe wall, thereby improving the fluid mixing effect.

[0104] In addition, in some embodiments, reference Figure 5 The first guide portion 30 has a first guide surface 302 , and the first guide surface 302 is tangent to the first guide section 2200 .

[0105] In some embodiments, reference Figure 5 The second guide portion 31 has a second guide surface 312 , and the second guide surface 312 is tangent to the fourth guide section 2211 .

[0106] It can be understood that when the fluid flows from the first guide section 2200 to the first guide surface 302, the tangent first guide surface 302 and the first guide section 2200 ensure smooth flow of the fluid. In the process of the fluid flowing to the first guide surface 302, the first guide surface 302 reduces the flow resistance effect of the fluid flowing along the first guide section 2200, which is beneficial to reduce the reduction in the fluid flow rate, and is beneficial for the fluid to have a good high-speed deviation effect along the first guide surface 302, thereby improving the mixing effect of the subsequent fluid impacting the pipe wall.

[0107] Similarly, when the fluid flows from the fourth guide section 2211 to the second guide surface 312, the tangent second guide surface 312 and the fourth guide section 2211 ensure smooth flow of the fluid. In the process of the fluid flowing to the second guide surface 312, the flow resistance effect of the second guide surface 312 on the fluid flowing along the fourth guide section 2211 is reduced, which is beneficial to reducing the reduction in the fluid flow rate, and is beneficial for the fluid to have a good high-speed deviation effect along the second guide surface 312, thereby improving the mixing effect of the subsequent fluid impacting the pipe wall.

[0108] In some embodiments, reference Figure 5 , the maximum width of the first tube 21 is D 1 , the maximum width of the second tube 22 is D 2 , the maximum width of the third tube 23 is D 3 , satisfied: D 2 ≥1.2D 1 .

[0109] In some embodiments, reference Figure 5 , satisfied: D 2 ≥1.2D 3 .

[0110] It should be noted that the actual flow cross-section of the sewage suction pipe 2 in this embodiment is roughly circular, so the maximum width of the first pipe 21, the maximum width of the second pipe 22, and the maximum width of the third pipe 23 are all the pipe diameters at the corresponding pipes. The maximum width of the second pipe 22 is set to be at least 1.2 times greater than the maximum width of the first pipe 21 and the third pipe 23, which is conducive to providing sufficient extension and adjustment space for the drainage part 3 structure, ensuring the high-speed deviation effect of the fluid in the second pipe 22, avoiding the drainage part 3 structure causing the internal flow area of ​​the second pipe 22 to be too low, and improving the flow capacity of the second pipe 22.

[0111] Preferably, in some embodiments, the maximum width of the first tube 21 is D 1 , the maximum width of the third tube 23 is D3 , meet: 28mm ≥ D 1 ≥22mm.

[0112] D 1 It can be any one of 22mm, 23mm, 24mm, 25mm, 26mm, 27mm, and 28mm, or a range value consisting of any two of them.

[0113] Preferably, in some embodiments, the following is satisfied: 28 mm ≥ D 3 ≥22mm.

[0114] D 3 It can be any one of 22mm, 23mm, 24mm, 25mm, 26mm, 27mm, and 28mm, or a range value consisting of any two of them.

[0115] The maximum width of the first tube 21 and the third tube 23 is set between 22 mm and 28 mm to meet the flow capacity of the suction pipe 2 to suck and output fluid, ensure that the suction pipe 2 can provide good suction force and suction efficiency, and facilitate cleaning and maintenance. When the maximum width of the first tube 21 and the third tube 23 is less than 22 mm, on the one hand, some impurities with larger sizes cannot be smoothly sucked into the suction pipe 2, limiting the suction capacity of the suction pipe 2, and on the other hand, it is not convenient to clean the impurities accumulated in the suction pipe 2. When the maximum width of the first tube 21 and the third tube 23 is greater than 28 mm, on the one hand, it is easy to reduce the suction force and suction effect of the suction pipe 2, and on the other hand, it also increases the size of the overall equipment, increases the occupied space and the overall use quality, and is not convenient for storage and use.

[0116] In addition, in some embodiments, reference Figures 2 to 5 The floor brush assembly also includes a second liquid spraying member 5.

[0117] In this embodiment, the second liquid spraying member 5 is disposed on the first tube 21 and is located upstream of the first liquid spraying member 4. Specifically, the liquid spraying direction of the second liquid spraying member 5 is toward the side of the sewage suction port 20, so as to spray liquid toward the fluid.

[0118] It should be noted that the above-mentioned first spray component 4 and second spray component 5 can both adopt an atomizing nozzle structure, which is intended to spray water mist against impurities such as dust and improve the mixing effect of liquid and impurities such as dust. The structural principle of the atomizing nozzle structure is existing technology and will not be repeated here.

[0119] By adding a second liquid spray component 5 upstream of the first liquid spray component 4, it is beneficial to further pre-spray liquid on impurities such as dust sucked up by the sewage suction pipe 2, thereby further improving the mixing effect of the dust and other impurities mixed with the liquid to form a fluid, which is beneficial to directly collect the mixed fluid, reduce the accumulation of dust and other impurities in the filter element, and improve the collection efficiency of dust and other impurities.

[0120] In addition, in some embodiments, in addition to the first spray component 4 and the second spray component 5, the number of spray components can be flexibly increased according to needs and the layout space of the floor brush body 1, and other spray components can be set at any position of the suction pipe 2, aiming to further mix the dust and other impurities sucked into the suction pipe 2 with liquid.

[0121] The present application also discloses a floor brush assembly, referring to Figure 3 The floor brush assembly includes a floor brush body 1, a roller brush 7, a water distribution component 8, a sewage suction pipe 2, at least two drainage parts 3 and a first liquid spray component 4.

[0122] The floor brush body 1 is provided with an arrangement cavity 10 for sequentially installing the roller brush 7, the water distribution member 8 and the sewage suction pipe 2. The sewage suction pipe 2 has a sewage suction port 20 facing the roller brush 7. The sewage suction pipe 2 includes a first pipe 21, a second pipe 22 and a third pipe 23 which are sequentially connected. The sewage suction port 20 is arranged upstream of the first pipe 21. The second pipe 22 has a first guide surface 220 and a second guide surface 221 which are opposite to each other. The first guide surface 220 includes a first guide section 2200 and a second guide section 2201. The first guide section 2200 is located upstream of the second guide section 2201. The second guide surface 221 includes a third guide section 2210 and a fourth guide section 2211. The third guide section 2210 is located upstream of the fourth guide section 2211. The first guide section 2200 is bent toward the third guide section 2210, and the fourth guide section 2211 is bent toward the second guide section 2201.

[0123] It should be noted that, in this embodiment, two drainage portions 3 are taken as an example, that is, at least two drainage portions 3 include a first drainage portion 30 and a second drainage portion 31. The first drainage portion 30 is arranged in the first guide section 2200 and extends toward the third guide section 2210 to guide the fluid transported in the first tube 21 toward the third guide section 2210. The drainage portion 3 is arranged in the fourth guide section 2211 and extends toward the second guide section 2201 to guide the fluid transported in the second tube 22 toward the second guide section 2201.

[0124] In other embodiments, the number of drainage parts 3 can be flexibly increased according to the bending structure of the sewage suction pipe 2. For example, in the present embodiment, the actual bending of the sewage suction pipe 2 is approximately an S-shaped structure, and two drainage parts 3 are set corresponding to the two bending areas. It can be understood that in other embodiments, when the sewage suction pipe 2 is provided with more bending areas, the corresponding number of drainage parts 3 can be increased to form a function of guiding the fluid in each bending area.

[0125] The first liquid spraying member 4 is arranged in the sewage suction pipe 2. In this embodiment, the first liquid spraying member 4 is actually arranged in the first tube 21 and is adjacent to the second tube 22, and the liquid spraying end of the first liquid spraying member 4 is arranged toward the first drainage portion 30. The first liquid spraying member 4 can spray liquid toward the fluid before the fluid contacts the third guide section 2210.

[0126] At the same time, the molding structure of the sewage suction pipe 2 is set to a bending approximately S-shaped structure, the third guide section 2210 can guide the fluid to make a turn greater than 90°, and the second guide section 2201 can guide the fluid to make a turn greater than 90°.

[0127] like Figure 3 As shown in FIG. 1 , taking the flow of a fluid as an example, the fluid is guided upward and deflected by the first guide portion 30 , and the fluid collides with the third guide section 2210 and turns downward along the third guide section 2210 . Figure 3 The turning angle γ shown in the figure represents the flow turning angle of the example fluid at this location. The fluid is guided downward by the second guide portion 31, and after the fluid hits the second guide section 2201, it turns upward along the second guide section 2201. Figure 3 The turning angle β shown in the figure represents the flow turning angle of the example fluid at that location.

[0128] It is understandable that the guiding and steering function of the second guide section 2201 and the guiding and steering function of the third guide section 2210 are available when the sewage suction pipe 2 is formed, and rely on the bending curvature characteristics to ensure that the fluid has a longer collision stroke in the second tube 22, thereby improving the mixing effect for the fluid. It is understandable that when the fluid moves and turns at an angle lower than 90° in the third guide section 2210, the fluid is prone to prematurely detach from the tube wall of the second tube 22, and the mixing effect will be weakened compared to the collision with the wall with a turning angle greater than 90°. When the fluid moves and turns at an angle lower than 90° in the second guide section 2201, the fluid is prone to prematurely detach from the tube wall of the second tube 22, and the mixing effect will be weakened compared to the collision with the wall with a turning angle greater than 90°.

[0129] During the use of the floor brush assembly, the dirt suction pipe 2 sucks dust and other impurities through the dirt suction port 20, and at the same time, the first liquid spraying member 4 can spray liquid toward the impurities, and the dust and other impurities can be mixed with the liquid before contacting the third guide section 2210, forming a fluid that passes through the first pipe 21, the second pipe 22 and the third pipe 23. During the movement of dust and other impurities in the second pipe 22, since the first guide section 2200 is bent toward the third guide section 2210, the dust and other impurities will be offset toward the third guide section 2210 at this time. Due to the wall-adhesive property of the liquid, the fluid can flow along the wall of the dirt suction pipe 2. On this basis, the dust and other impurities are guided to move toward the third guide section 2210 by at least one guide portion 3 provided on the first guide section 2200, and when moving from the first guide section 2200 to the third guide section 2210, the dust and other impurities and the liquid can fully collide with the third guide section 2210 and further mix, thereby improving the mixing effect of dust and other impurities and the liquid. In addition, the fluid can make a turn greater than 90° when continuing to move after colliding at the third guide section 2210, thereby ensuring that the fluid has a longer collision stroke in the second tube 22, improving the mixing effect for the fluid, and when the fluid moves at a turning angle of less than 90° in the third guide section 2210, the fluid is easy to prematurely detach from the tube wall of the second tube 22, and the mixing effect will be weakened compared to the collision with the wall with a turn greater than 90°. Similarly, since the fourth guide section 2211 is bent toward the second guide section 2201, the fluid that moves to the fourth guide section 2211 in accordance with the third guide section 2210 will be offset toward the second guide section 2201. On this basis, at least one guide portion 3 provided in the fourth guide section 2211 guides the fluid to move toward the second guide section 2201, so that the fluid can fully collide with the second guide section 2201 and further mix, which is conducive to further improving the mixing effect of impurities such as dust and liquid. In addition, the fluid can continue to move after colliding at the second guide section 2201 and turn more than 90°, thereby also ensuring that the fluid has a longer collision stroke in the second tube 22, improving the mixing effect for the fluid, and when the fluid moves at a turning angle of less than 90° in the second guide section 2201, the fluid is likely to prematurely detach from the tube wall of the second tube 22, and the mixing effect will be weakened compared to the wall collision with a turning angle of more than 90°. Dust and other impurities are mixed with liquid through multiple wall collisions, which is conducive to directly collecting the mixed fluid, reducing the accumulation of dust and other impurities on the filter element, and improving the collection efficiency of dust and other impurities.

[0130] In addition, the present application also discloses a floor brush assembly, referring to Figure 8The difference between the floor brush assembly and the above-mentioned embodiments is that only one drainage portion 3 is provided, that is, taking the first drainage portion 30 only provided on the first guide section 2200 as an example, the first drainage portion 30 is provided on the first guide section 2200 and extends toward the third guide section 2210 to guide the fluid transported in the first tube 21 toward the third guide section 2210.

[0131] During the use of the floor brush assembly, the suction pipe 2 sucks in dust and other impurities through the suction port 20. At the same time, the first spray member 4 can spray liquid toward the impurities. Dust and other impurities can be mixed with the liquid before contacting the third guide section 2210, forming a fluid that passes through the first tube 21, the second tube 22 and the third tube 23 in turn. During the movement of impurities such as dust in the second tube 22, since the first guide section 2200 is bent toward the third guide section 2210, the impurities such as dust will be offset toward the third guide section 2210. Due to the wall-adhesive property of the liquid, the fluid can flow along the tube wall of the suction tube 2. On this basis, at least one guide portion 3 provided on the first guide section 2200 guides the impurities such as dust to move toward the third guide section 2210. When moving from the first guide section 2200 to the third guide section 2210, the impurities such as dust and the liquid can fully collide with the third guide section 2210 and further mix, thereby improving the mixing effect of the impurities such as dust and the liquid, which is beneficial to directly collect the mixed fluid, reduce the accumulation of impurities such as dust on the filter element, and improve the collection efficiency of impurities such as dust.

[0132] Correspondingly, a cleaning device according to an embodiment of the present application includes the above-mentioned floor brush assembly.

[0133] It should be noted that the cleaning device can be a floor scrubber or other cleaning products with a vacuuming function, which will not be described in detail here.

[0134] When the cleaning equipment is in use, the floor brush assembly of the cleaning equipment sucks in dust and other impurities through the suction port 20 of the suction pipe 2. At the same time, the first spray component 4 can spray liquid toward the impurities. Dust and other impurities can be mixed with the liquid before they contact the third guide section 2210. The mixed fluid is successively offset toward the third guide section 2210 and toward the second guide section 2201, thereby completing multiple wall-impact mixing actions. The fluid is guided by the drainage part 3 to further fully hit the wall to further improve the mixing effect of dust and other impurities and liquid, which is conducive to directly collecting the mixed fluid, reducing the accumulation of dust and other impurities in the filter element, and improving the collection efficiency of dust and other impurities.

[0135] In addition, refer to Figure 2 , Figure 6 and Figure 7In some embodiments, the cleaning device further includes a clean liquid tank (not shown in the figure) and a dirty liquid tank (not shown in the figure). It should be noted that the clean liquid tank is also used to store liquid used in the wet cleaning process of the cleaning device. The liquid can be a cleaning solution or clean water. The dirty liquid tank is used to store a mixed fluid of collected dust and liquid during the pure vacuuming process of the cleaning device, and to collect the used liquid in the clean liquid tank during the wet cleaning process of the cleaning device.

[0136] The floor brush assembly also includes a liquid pump 6 , which is configured to pump the liquid in the clean liquid tank and deliver it to the first liquid spraying member 4 and the second liquid spraying member 5 , and at the same time, the liquid pump 6 is configured to pump the liquid in the clean liquid tank and deliver it to the water dividing member 8 .

[0137] When using the cleaning device, the liquid used for cleaning is stored in the liquid cleaning tank in advance, and the liquid pump 6 directly extracts the liquid in the cleaning liquid for the first liquid spraying part 4 and the second liquid spraying part 5 to spray toward dust and other impurities. The output end of the liquid pump 6 can be connected to the first liquid spraying part 4 and the second liquid spraying part 5 respectively using a three-way pipe 60 structure, and the extraction end of the liquid pump 6 is connected to the liquid cleaning tank. There is no need to add an additional liquid supply structure for the first liquid spraying part 4, which reduces the impact on the volume of the cleaning device itself, facilitates unified replenishment of the liquid source, and reduces the need for replenishment operation. At the same time, the water distribution part 8 and the first liquid spraying part 4 can share the liquid pump 6. When the cleaning device wet cleans the surface to be cleaned, the liquid pump 6 can pump the liquid source to the water distribution part 8 and transport it toward the roller brush 7, thereby wetting the roller brush 7 and performing wet cleaning. When the cleaning device only needs to perform dust removal operation, the liquid pump 6 can be controlled to only transport the liquid source to the first liquid spraying part 4. There is no need to add an additional liquid supply structure for the first liquid spraying part 4, which reduces the impact on the volume of the cleaning device itself, facilitates unified replenishment of the liquid source, and reduces the need for replenishment operation.

[0138] In addition, it should be noted that, taking the cleaning device in which the first drainage part 30 and the second drainage part 31 are arranged in the suction pipe 2 of the floor brush assembly as an example, the cleaning device is used to absorb dust alone, such as dust and other impurities on the floor and carpet. The collection and separation efficiency of the dust of the above design can be measured by experiment:

[0139] By measuring the volume of the dirty liquid tank, the dust absorption amount w that the dirty liquid tank can store is obtained. During the test, the cleaning equipment is first run for 15 seconds, and then the dust absorption test is carried out after the absorption state is stable.

[0140] The cleaning equipment is controlled to absorb the test amount of dust w within 1 minute. By weighing the weight of the HEPA before and after the test, the weight increase y of the HEPA after absorbing the dust can be obtained, that is, the amount of dust not collected. The remaining dust amount can be reversed to the actual collection amount of the dust and liquid tank (wy), and then the dust collection efficiency is obtained as [(wy) / w]×100%. By setting the first data currently verified by the test, the efficiency can reach 99.6%.

[0141] Correspondingly, a cleaning system according to an embodiment of the present application includes the above-mentioned cleaning device and also includes a base station or a charging stand compatible with the cleaning device.

[0142] It can be understood that when using a base station compatible with the cleaning equipment, the base station can provide the cleaning equipment with functions such as liquid supply, liquid drainage, self-cleaning, drying and charging, and when using a charging stand, the charging stand can provide the cleaning equipment with functions such as charging, self-cleaning and drying.
