Description

Technical Field

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

[0002] During operation, cleaning equipment such as floor scrubbers need to continuously spray liquid toward the roller brush to wet the roller brush, thereby facilitating the roller brush to perform cleaning operations.

[0003] At present, cleaning equipment such as floor scrubbers generally have the problem of uneven liquid spraying on the roller brush, which easily causes the two ends of the roller brush to be wetted later than the middle part in the length direction. At this time, due to the uneven wetting of the roller brush, it is easy to cause water stains when cleaning the surface to be cleaned, affecting the cleaning effect and cleaning efficiency of the roller brush. For example, a Chinese patent with announcement number CN218784421U discloses a floor brush mechanism, including a floor brush body, a heating component, a liquid supply component and a third pipeline structure. If the liquid spray hole of the floor brush mechanism does not use steam, it is impossible to achieve good liquid atomization and uniform liquid spraying. Utility Model Content

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

[0005] Technical solution: A liquid separation component, comprising:

[0006] A liquid separation shell, wherein the liquid separation shell has a containing cavity, and the liquid separation shell is provided with a liquid inlet connected to the containing cavity and a plurality of liquid spray holes, wherein the liquid spray holes are used to spray liquid toward the roller brush, and the total flow area of ​​the plurality of liquid spray holes is smaller than the flow area of ​​the liquid inlet;

[0007] The total flow area S of the plurality of liquid spray holes satisfies: 0.35 mm 2 ≤S≤2.51mm 2 ;

[0008] The flow area S1 of a single liquid spray hole satisfies: 0.01mm 2 ≤S1≤0.16mm 2 ;

[0009] The distance D between adjacent liquid spray holes satisfies: 6mm≤D≤18.6mm.

[0010] By adopting the above technical scheme, when the liquid separation component is used to spray liquid toward the roller brush, the liquid source is transported from the liquid inlet to the accommodating chamber. Since the total flow area of ​​the multiple liquid spray holes is smaller than the flow area of ​​the liquid inlet, a liquid spray pressure is formed at the liquid spray holes, which is beneficial to increasing the liquid spray speed of the liquid spray holes and atomizing the liquid sprayed from the liquid spray holes, thereby expanding the spray range of the liquid spray holes toward the roller brush and enhancing the wetting and penetration effect on the roller brush. The liquid spray holes actually need to be set on the surface of the liquid separation component opposite to the roller brush. The length dimension of the liquid separation component needs to be adapted to the length dimension of the roller brush. When setting the size of each liquid spray hole, if the opening of the liquid spray hole is too large, it is easy to cause the flow area of ​​the liquid spray hole and the total flow area of ​​all liquid spray holes to be too large. At this time, the liquid spray pressure at the liquid spray hole and the flow rate of the sprayed liquid are reduced, and the actual spraying of the liquid spray hole, the atomization effect and uniformity of the wetting roller brush are reduced. If the opening of the liquid spray hole is too small, it is easy to cause the flow area of ​​the liquid spray hole and the total flow area of ​​all liquid spray holes to be too large. The total flow area of ​​the holes is too small. At this time, the spray pressure and the flow rate of the sprayed liquid at the spray holes are both high, and the spray holes are more likely to be blocked at this time, and the water supply pressure in the liquid separation component is too large. At the same time, the number and spacing of the spray holes need to be reasonably arranged to improve the uniformity of the spray of each spray hole on the roller brush. If the spacing between adjacent spray holes is too large, it is easy to cause insufficient spray coverage, and if the spacing between adjacent spray holes is too small, the density of the spray holes is too large, resulting in excessive cross-coverage of the spray coverage of adjacent spray holes, which will cause uneven spraying and wetting of the roller brush. Combined with the conventionally used pump water flow rate and the pressure range that the water supply pipeline of the liquid separation component toward the spray hole can withstand, a reasonable aperture and number of the spray holes are set, and the single flow area, total flow area and spacing between adjacent spray holes with better uniformity of spraying and wetting the roller brush can be obtained. The total flow area of ​​multiple spray holes is further set at 0.35mm 2 Up to 2.51mm 2 The flow area of ​​a single spray hole is set at 0.01mm 2 Up to 0.16mm 2 The distance between adjacent spray holes is set between 6 mm and 18.6 mm, which is beneficial to further optimize the atomization effect of the spray liquid from multiple spray holes and the uniform wetting effect of the spray roller brush, thereby improving the problem of water stains caused by uneven wetting of the roller brush when cleaning the surface to be cleaned, and improving the cleaning efficiency of the roller brush.

[0013] The total flow area S of the plurality of liquid spray holes satisfies: 0.35 mm2 ≤S≤2.51mm 2 ;

[0015] The number a of the liquid spray holes satisfies: 15≤a≤33.

[0016] By adopting the above technical scheme, when the liquid separation component is used to spray liquid toward the roller brush, the liquid source is transported from the liquid inlet to the accommodating chamber. Since the total flow area of ​​the multiple liquid spray holes is smaller than the flow area of ​​the liquid inlet, a liquid spray pressure is formed at the liquid spray holes, which is beneficial to increasing the liquid spray speed of the liquid spray holes and atomizing the liquid sprayed from the liquid spray holes, thereby expanding the spray range of the liquid spray holes toward the roller brush and enhancing the wetting and penetration effect on the roller brush.

The total flow area of ​​multiple spray holes is further set at 0.35mm 2 Up to 2.51mm 2 The flow area of ​​a single spray hole is set at 0.01mm 2 Up to 0.16mm 2 Setting the number of the liquid spray holes between 15 and 33 is beneficial to further optimize the atomization effect of the liquid sprayed by the multiple liquid spray holes and the uniform wetting effect of the spray roller brush, thereby improving the problem of water stains caused by uneven wetting of the roller brush when cleaning the surface to be cleaned, and improving the cleaning efficiency of the roller brush.

At this time, the liquid spray pressure at the liquid spray hole and the flow rate of the sprayed liquid are reduced, and the actual spraying of the liquid spray hole, the atomization effect and uniformity of the wetting roller brush are reduced. If the opening of the liquid spray hole is too small, it is easy to cause the flow area of ​​the liquid spray hole and the total flow area of ​​all liquid spray holes to be too large. The total flow area of ​​the holes is too small. At this time, the spray pressure and the flow rate of the sprayed liquid at the spray holes are both high, and the spray holes are more likely to be blocked at this time, and the water supply pressure in the liquid separation component is too large. At the same time, the number and spacing of the spray holes need to be reasonably arranged to improve the uniformity of the spray of each spray hole on the roller brush. If the spacing between adjacent spray holes is too large, it is easy to cause insufficient spray coverage, and if the spacing between adjacent spray holes is too small, the density of the spray holes is too large, resulting in excessive cross-coverage of the spray coverage of adjacent spray holes, which will cause uneven spraying and wetting of the roller brush.

The total flow area of ​​multiple spray holes is further set at 0.35mm 2 Up to 2.51mm 2Setting the distance between adjacent spray holes between 6 mm and 18.6 mm, and setting the number of spray holes between 15 and 33, is beneficial to further optimize the atomization effect of the spray liquid from multiple spray holes and the uniform wetting effect of the spray roller brush, thereby improving the problem of water stains caused by uneven wetting of the roller brush when cleaning the surface to be cleaned, and improving the cleaning efficiency of the roller brush.

[0023] In some embodiments, the total flow area S of the plurality of liquid spray holes satisfies: 0.35 mm 2 ≤S≤1.84mm 2 .

[0024] By adopting the above technical solution, the total flow area of ​​the multiple spray holes is further set to 0.35mm 2 Up to 1.84mm 2 It is beneficial to further optimize the atomization effect of the liquid spraying holes and the uniform wetting effect of the spray roller brush, thereby improving the cleaning effect and cleaning efficiency of the roller brush.

[0025] In some embodiments, the flow area S1 of a single liquid spray hole satisfies: 0.017 mm 2 ≤S1≤0.071mm 2 .

[0026] By adopting the above technical solution, the flow area of ​​a single spray hole is further set at 0.017mm 2 Up to 0.071mm 2 It is beneficial to further optimize the atomization effect of the liquid spraying holes and the uniform wetting effect of the spray roller brush, thereby improving the cleaning effect and cleaning efficiency of the roller brush.

[0027] In some embodiments, the distance D between adjacent liquid spray holes satisfies: 6.5 mm ≤ D ≤ 14 mm.

[0028] By adopting the above technical solution, the distance between adjacent spray holes is further set between 6.5 mm and 14 mm, which is beneficial to further optimize the atomization effect of the spray liquid from multiple spray holes and the uniform wetting effect of the spray roller brush, thereby improving the cleaning effect and cleaning efficiency of the roller brush.

[0029] In some embodiments, the number a of the liquid spray holes satisfies: 20≤a≤30.

[0030] By adopting the above technical solution, the number of the spray holes is further set between 15 and 33, which is beneficial to further optimize the atomization effect of the spray liquid from multiple spray holes and the uniform wetting effect of the spray roller brush, thereby improving the cleaning effect and cleaning efficiency of the roller brush.

[0031] In some embodiments, the liquid separation shell has a liquid spraying state of spraying liquid toward the roller brush. In the liquid spraying state, an initial velocity V0 of the liquid flow sprayed from the liquid spraying hole satisfies: 1m / s≤V0≤5m / s.

[0032] By adopting the above technical scheme, the speed of the liquid flow sprayed from the spray hole in the spraying state can reach 1m / s to 5m / s, which is beneficial to increase the spray distance of the liquid flow sprayed from the spray port and the penetration ability of the wet roller brush, thereby improving the efficiency of the wet roller brush to improve the cleaning effect and cleaning efficiency of the roller brush.

[0033] In some embodiments, the liquid separation shell includes a main body and a liquid separation member, the main body and the liquid separation member surround the accommodating cavity, the liquid inlet is arranged on the main body, and the liquid spray hole is arranged on the liquid separation member.

When the liquid separation shell is in working state, the liquid source is introduced into the receiving chamber from the liquid inlet and sprayed out from the liquid spray hole, thereby realizing the input and output of the liquid source into and out of the liquid separation shell.

[0035] In some embodiments, the main body and the liquid separation member are separate assembly structures;

[0036] The main body has the accommodating cavity, and the main body is provided with an opening communicating with the accommodating cavity, and the liquid separating member is covered on the opening.

[0037] By adopting the above technical solution, the split-assembled main body and the liquid-separating parts can be independently disassembled and assembled, which is convenient for the maintenance and replacement of the liquid-separating shell. In addition, the split-assembled main body and the liquid-separating parts can be easily processed independently, thereby reducing the processing difficulty of the overall liquid-separating shell and improving the yield rate of the liquid-separating shell manufacturing.

[0038] In some embodiments, the liquid separating member has a length direction, and a dimension L of the liquid separating member in the length direction satisfies: 200 mm≤L≤280 mm.

[0039] By adopting the above technical solution, the length of the liquid separator is set between 200mm and 280mm to match the length of the roller brush, which is beneficial for the spray holes arranged on the liquid separator to evenly spray liquid to the roller brush, thereby improving the uniformity of wetting the roller brush.

[0040] In some embodiments, the main body and the liquid separation member are an integral structure.

[0041] By adopting the above technical solution, the main body and the liquid separation part of the integrated structure simplify the assembly process of the main body and the liquid separation part compared with the main body and the liquid separation part of the split structure, which is beneficial to improving the production efficiency of the overall liquid separation shell.

[0042] In some embodiments, the liquid separation shell has a length direction, and at least part of the liquid injection holes are distributed along the length direction of the liquid separation shell.

[0043] By adopting the above technical solution, the liquid spray holes are distributed along the length direction of the liquid separation shell, and the corresponding roller brush can also be adapted and installed with the liquid separation shell along the length direction, which is conducive to the liquid spray holes to evenly spray liquid to the roller brush and improve the uniformity of the roller brush wetting.

[0044] In some embodiments, the liquid separation shell further includes a cover body, which is disposed on a side of the liquid separation member away from the main body, and a jet cavity is penetrated through the cover body, and a plurality of the liquid spray holes are connected to the jet cavity to spray liquid toward the roller brush.

[0045] By adopting the above technical solution, during the operation of the liquid separation shell, each liquid spray hole sprays liquid toward the jet chamber. At this time, the atomized liquid source can be sprayed along the jet chamber onto the roller brush, that is, the jet chamber can guide the atomized liquid source to be evenly dispersed on the roller brush, thereby improving the uniformity of the roller brush wetting.

[0046] In some embodiments, the jet chamber is provided with a;

[0047] Alternatively, the jet chamber is provided with a plurality of jet chambers, and each jet chamber is connected to at least one of the liquid spray holes.

[0048] By adopting the above technical scheme, only one jet chamber can be set, that is, multiple spray holes all spray liquid to the roller brush from one jet chamber. In addition, the jet chamber can also be set to be multiple and spaced from each other, and each jet chamber can correspond to at least one spray hole, which is beneficial to further optimize the guiding effect of the jet chamber for each spray hole and improve the uniformity of wetting the roller brush.

[0049] In some embodiments, the cover body includes a base and a liquid separation part arranged on the base, the jet chamber is arranged on the base, and the liquid separation shell has a spraying state of spraying liquid toward the roller brush. In the spraying state, the jet chamber sprays liquid toward the roller brush and wets the roller brush, and the liquid separation part is used to abut against the wetted roller brush and disperse the liquid on the roller brush as the roller brush rotates.

[0050] By adopting the above technical scheme, in the liquid spraying state, the roller brush rotates and makes part of itself face the jet chamber to receive the liquid sprayed from the jet chamber, thereby moistening the roller brush. Subsequently, the moistened part of the roller brush is pressed against and squeezed by the liquid separator to disperse the liquid accumulated on the roller brush, thereby further improving the uniformity of the wetting of the roller brush, which is beneficial to improving the cleaning effect and efficiency of the roller brush.

[0051] In some embodiments, the cover and the main body are separate assembly structures;

[0052] The cover body and the liquid separation component are a separate assembly structure, or the cover body and the liquid separation component are an integrated structure.

[0053] By adopting the above technical solution, the cover body, the main body and the liquid separator are all independent components, and the cover body can be independently disassembled and assembled relative to the main body and the liquid separator, which is convenient for the maintenance and replacement of the cover body. In addition, the cover body, the liquid separator and the main body assembled separately are convenient for independent processing, thereby reducing the processing difficulty of the overall liquid separator shell and improving the yield rate of the liquid separator shell manufacturing.

[0057] Correspondingly, a floor brush described in an embodiment of the present application includes the above-mentioned liquid separation component and a roller brush, and the liquid separation component is used to spray liquid toward the roller brush.

[0058] By adopting the above technical solution, during the use of the floor brush, the liquid separation component can evenly spray the liquid source toward the roller brush, thereby improving the wetting uniformity of the roller brush, thereby improving the cleaning effect and cleaning efficiency of the floor brush.

[0059] In some embodiments, the floor brush also includes a liquid pump, which is used to pump liquid toward the liquid separation component. The liquid separation component has a spraying state of spraying liquid toward the roller brush. In the spraying state, the pumping liquid flow rate Q of the liquid pump satisfies: 0≤Q≤160g / min.

[0060] By adopting the above technical solution, the floor brush can flexibly use a liquid pump that can pump liquid at 0 to 160g / min, thereby delivering the liquid source toward the liquid separation component to stably spray the liquid source toward the roller brush, thereby achieving uniform wetting of the roller brush and improving the cleaning effect and efficiency of the roller brush.

[0061] In some embodiments, in the liquid spraying state, the pump liquid flow rate Q of the liquid pump satisfies: 20g / min≤Q≤150g / min.

[0062] By adopting the above technical solution, the pump liquid flow rate of the liquid pump is further set at 20g / min to 150g / min, which is beneficial to ensure that the amount of liquid source delivered to the liquid separation component per unit time is sufficient, so as to stably spray the liquid source toward the roller brush, achieve uniform wetting of the roller brush, and improve the cleaning effect and cleaning efficiency of the roller brush.

[0063] Correspondingly, a cleaning device described in an embodiment of the present application includes the above-mentioned liquid separation component or floor brush.

[0064] By adopting the above technical scheme, the cleaning equipment can flexibly use the liquid-separating component or the floor brush alone to meet the needs of different usage scenarios. When the liquid-separating component is used alone, the cleaning equipment has the effect of atomizing the liquid source and spraying the liquid source evenly. When the floor brush is used, during the operation of the cleaning equipment, the liquid-separating component of the floor brush evenly sprays the atomized liquid source toward the rotating roller brush, thereby improving the wetting uniformity of the roller brush, thereby improving the cleaning effect and cleaning efficiency of the cleaning equipment.

[0065] 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.

[0066] 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.

[0067] Beneficial effect: When the liquid separation component is used in the embodiment of the present application to spray liquid toward the roller brush, the liquid source is transported from the liquid inlet to the accommodating chamber. Since the total flow area of ​​the multiple liquid spray holes is smaller than the flow area of ​​the liquid inlet, a liquid spray pressure is formed at the liquid spray holes, which is beneficial to increasing the liquid spray speed of the liquid spray holes and atomizing the liquid sprayed from the liquid spray holes, thereby expanding the spray range of the liquid spray holes toward the roller brush and enhancing the wetting and penetration effect on the roller brush. The liquid spray holes actually need to be set on the surface of the liquid separation component opposite to the roller brush. The length dimension of the liquid separation component needs to be adapted to the length dimension of the roller brush. When setting the size of each liquid spray hole, if the opening of the liquid spray hole is too large, it is easy to cause the flow area of ​​the liquid spray hole and the total flow area of ​​all the liquid spray holes to be too large. At this time, the liquid spray pressure at the liquid spray hole and the flow rate of the sprayed liquid are reduced, and the actual spraying of the liquid spray hole, the atomization effect and the uniformity of the wetting roller brush will all be reduced. If the opening of the liquid spray hole is too small, it is easy to cause the flow area of ​​the liquid spray hole and the total flow area of ​​all the liquid spray holes to be too large. The total flow area of ​​the holes is too small. At this time, the spray pressure and the flow rate of the sprayed liquid at the spray holes are both high, and the spray holes are more likely to be blocked at this time, and the water supply pressure in the liquid separation component is too large. At the same time, the number and spacing of the spray holes need to be reasonably arranged to improve the uniformity of the spray of each spray hole on the roller brush. If the spacing between adjacent spray holes is too large, it is easy to cause insufficient spray coverage, and if the spacing between adjacent spray holes is too small, the density of the spray holes is too large, resulting in excessive cross-coverage of the spray coverage of adjacent spray holes, which will cause uneven spraying and wetting of the roller brush. Combined with the conventionally used pump water flow rate and the pressure range that the water supply pipeline of the liquid separation component toward the spray hole can withstand, a reasonable aperture and number of the spray holes are set, and the single flow area, total flow area and spacing between adjacent spray holes with better uniformity of spraying and wetting the roller brush can be obtained. The total flow area of ​​multiple spray holes is further set at 0.35mm 2 Up to 2.51mm 2 It is beneficial to further optimize the atomization effect of the liquid sprayed by multiple spray holes and the uniform wetting effect of the spray roller brush, improve the problem of water stains caused by uneven wetting of the roller brush when cleaning the surface to be cleaned, and improve the cleaning efficiency of the roller brush.

DETAILED DESCRIPTION

[0078] 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.

[0079] 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.

[0080] At present, during the operation of cleaning equipment such as floor scrubbers, liquid needs to be sprayed toward the roller brush through a liquid spraying structure to quickly wet the roller brush, so that the roller brush can clean the surface to be cleaned. The liquid spraying structure usually needs to adapt to the liquid spraying holes set on the roller brush for spraying liquid, but the number of liquid spraying holes is limited, and it is difficult to spray liquid evenly on the roller brush, resulting in the roller brush often appearing in the middle part of the length direction Wetting earlier than the two ends, the overall wetting uniformity is poor, and the roller brush is prone to produce water stains on the surface to be cleaned, affecting the cleaning effect and cleaning efficiency of the roller brush;

[0081] In addition, the spray structure of cleaning equipment such as floor scrubbers also has the problem of slow liquid discharge speed, short spray distance, and the sprayed liquid tends to flow to low places, which affects the user experience of the cleaning equipment.

[0082] In view of this, combined with Figures 1 to 5 The embodiments of the present application provide a liquid separation component, a floor brush, a cleaning device and a cleaning system, aiming to overcome at least one of the above-mentioned technical problems.

[0083] In the following embodiments, intersecting length direction X and width direction Y, as well as rotation direction W are introduced, wherein the length direction X is parallel to the length direction of the entire liquid separation component in this embodiment, the width direction Y is parallel to the width direction of the entire liquid separation component in this embodiment, and the rotation direction W indicates one of the rotation directions of the roller brush.

[0084] Reference Figure 1 and Figure 2, a liquid separation component includes a liquid separation shell 1. The liquid separation shell 1 has a accommodating chamber 10, and the liquid separation shell 1 is provided with a liquid inlet 11 connected to the accommodating chamber 10 and a plurality of liquid spray holes 12. Among them, in the present embodiment, the liquid separation shell 1 has two sides arranged oppositely in the width direction Y, the liquid inlet 11 is arranged on one side of the liquid separation shell 1 in the width direction Y, and the plurality of liquid spray holes 12 are arranged on the other side of the liquid separation shell 1 in the width direction Y. The liquid inlet 11 and the liquid spray holes 12 are distributed on both sides of the liquid separation shell 1 in the width direction Y to provide sufficient space for the external infusion pipeline for the liquid inlet 11 to avoid affecting the arrangement and liquid spraying of the liquid spray holes 12. It can be understood that one side of the liquid separation shell 1 where the liquid spray hole 12 is arranged is used to be arranged toward the roller brush, so that the liquid spray hole 12 can spray liquid toward the roller brush.

[0085] It should be noted that the above-mentioned roller brush can be arranged on the surface to be cleaned and move along a predetermined path to clean the surface to be cleaned. The surface to be cleaned can be the ground or the like.

[0086] The total flow area of ​​the plurality of liquid spray holes 12 is smaller than the flow area of ​​the liquid inlet 11 .

[0087] The total flow area S of the plurality of liquid spray holes 12 satisfies: 0.35 mm 2 ≤S≤2.51mm 2, that is, the value of S can be 0.35, 0.36, 0.37, 0.38, 0.39, 0.40, 0.41, 0.42, 0.43, 0.44, 0.45, 0.46, 0.47, 0.48, 0.49, 0.50, 0.51, 0.52, 0.53, 0.54, 0.55, 0.56, 0.57, 0 .58, 0.59, 0.60, 0.61, 0.62, 0.63, 0.64, 0.65, 0.66, 0.67, 0.68, 0.69, 0.70, 0.71, 0.72, 0.73, 0.74, 0.75, 0.76, 0.77, 0.78, 0.79, 0.80, 0.81, 0.82, 0 .83, 0.84, 0.85, 0.86, 0.87, 0.88, 0.89, 0.90, 0.91, 0.92, 0.93, 0.94, 0.95, 0.96, 0.97, 0.98, 0.99, 1.00, 1.01, 1.02, 1.03, 1.04, 1.05, 1.06, 1.07, 1 .08, 1.09, 1.10, 1.11, 1.12, 1.13, 1.14, 1.15, 1.16, 1.17, 1.18, 1.19, 1.20, 1.21, 1.22, 1.23, 1.24, 1.25, 1.26, 1.27, 1.28, 1.29, 1.30, 1.31, 1.32, 1 .33, 1.34, 1.35, 1.36, 1.37, 1.38, 1.39, 1.40, 1.41, 1.42, 1.43, 1.44, 1.45, 1.46, 1.47, 1.48, 1.49, 1.50, 1.51, 1.52, 1.53, 1.54, 1.55, 1.56, 1.57, 1 .58, 1.59, 1.60, 1.61, 1.62, 1.63, 1.64, 1.65, 1.66, 1.67, 1.68, 1.69, 1.70, 1.71, 1.72, 1.73, 1.74, 1.75, 1.76, 1.77, 1.78, 1.79, 1.80, 1.81, 1.82, 1 .83, 1.84, 1.85, 1.86, 1.87, 1.88, 1.89, 1.90, 1.91, 1.92, 1.93, 1.94, 1.95, 1.96, 1.97, 1.98, 1.99, 2.00, 2.01, 2.02, 2.03, 2.04, 2.05, 2.06, 2.07, 2 .08, 2.09, 2.10, 2.11, 2.12, 2.13, 2.14, 2.15, 2.16, 2.17, 2.18, 2.19, 2.20, 2.21, 2.22, 2.23, 2.24, 2.25, 2.26, 2.27, 2.28, 2.29, 2.30, 2.31, 2.32, 2.33, 2.34, 2.35, 2.36, 2.37, 2.38, 2.39, 2.40, 2.41, 2.42, 2.43, 2.44, 2.45, 2.46, 2.47, 2.48, 2.49, 2.50, 2.51, or a range of any two of them. .

[0088] The flow area S1 of a single spray hole 12 satisfies: 0.01mm 2 ≤S1≤0.16mm 2 That is, the value of S1 can be any one of 0.01, 0.02, 0.03, 0.04, 0.05, 0.06, 0.07, 0.08, 0.09, 0.10, 0.11, 0.12, 0.13, 0.14, 0.15, and 0.16, or a range of any two of them.

[0089] The distance D between adjacent spray holes 12 satisfies: 6 mm ≤ D ≤ 18.6 mm, that is, the value of D can be 6.0, 6.1, 6.2, 6.3, 6.4, 6.5, 6.6, 6.7, 6.8, 6.9, 7.0, 7.1, 7.2, 7.3, 7.4, 7.5, 7.6, 7.7, 7.8, 7.9, 8.0, 8.1, 8.2, 8.3, 8.4, 8.5, 8.6, 8.7, 8.8, 8.9, 9.0, 9.1 , 9.2, 9.3, 9.4, 9.5, 9.6, 9.7, 9.8, 9.9, 10.0, 10.1, 10.2, 10.3, 10.4, 10.5, 10.6, 10.7, 10.8, 10.9, 11.0, 11.1, 11.2, 11.3, 11.4, 11.5, 11.6, 11.7, 11.8, 11.9, 12.0, 12.1, 12.2, 12.3, 12.4, 12.5 , 12.6, 12.7, 12.8, 12.9, 13.0, 13.1, 13.2, 13.3, 13.4, 13.5, 13.6, 13.7, 13.8, 13.9, 14.0, 14.1, 14.2, 14.3, 14.4, 14.5, 14.6, 14.7, 14.8, 14.9, 15.0, 15.1, 15.2, 15.3, 15.4, 15.5, 15.6, 15.7, 1 The range value consists of any one of 18.0, 18.1, 18.2, 18.3, 18.4, 18.5, and 18.6, or any two of the following.

[0090] It should be noted that in this embodiment, the flow cross-sectional shapes of the liquid inlet 11 and the liquid spray hole 12 are both circular in design, that is, the flow area S1 of a single liquid spray hole 12 can be directly calculated by measuring the radial dimension d of the liquid spray hole 12, specifically S1 = πd 2 / 4, after calculating the flow area S1 of a single spray hole 12, the total flow area S of multiple spray holes 12 can be obtained by multiplying the designed number of spray holes 12. The distance D between adjacent spray holes 12 can be directly measured by a ruler.

[0091] Similarly, the flow area of ​​the liquid inlet 11 can also be directly calculated by measuring the radial dimension of the liquid inlet 11, which will not be described in detail here.

[0092] In other embodiments, the flow cross-section of the liquid inlet 11 and the liquid spray hole 12 may also be a regular polygon such as a triangle, rectangle, ellipse, hexagon, etc., and the area calculation of the corresponding flow cross-section may be calculated by measuring the required size parameters using the corresponding polygon area calculation formula. In addition, in other embodiments, the flow cross-section of the liquid inlet 11 and the liquid spray hole 12 may also be an irregular shape, and the area of ​​the irregular shape may be calculated by scanning the flow cross-section of the liquid inlet 11 and the liquid spray hole 12 through a computer, which will not be described in detail here.

[0093] When the liquid separation assembly is used to spray liquid toward the roller brush, the liquid source is transported from the liquid inlet 11 to the accommodating chamber 10. Since the total flow area of ​​the plurality of liquid spray holes 12 is smaller than the flow area of ​​the liquid inlet 11, a liquid spray pressure is formed at the liquid spray holes 12, which is beneficial to increase the liquid spray speed of the liquid spray holes 12 and atomize the liquid sprayed from the liquid spray holes 12, thereby expanding the spray range of the liquid spray holes 12 toward the roller brush and enhancing the wetting and penetration effect on the roller brush. The wetted roller brush rolls and cleans the surface to be cleaned, thereby realizing a rapid cleaning function.

[0094] The liquid spray hole 12 actually needs to be set on the surface opposite to the liquid separation component and the roller brush. The length of the liquid separation component needs to be adapted to the length of the roller brush. When setting the size of each liquid spray hole 12, if the opening of the liquid spray hole 12 is too large, it is easy to cause the flow area of ​​the liquid spray hole 12 and the total flow area of ​​all the liquid spray holes 12 to be too large. At this time, the liquid spray pressure at the liquid spray hole 12 and the flow rate of the liquid sprayed out will decrease, and the actual spraying and wetting of the roller brush by the liquid spray hole 12 will be reduced. The atomization effect and uniformity of the liquid spray hole 12 will be reduced. If the opening of the liquid spray hole 12 is too small, it is easy to cause the flow area of ​​the liquid spray hole 12 and the total flow area of ​​all the liquid spray holes 12 to be too small. At this time, the liquid spray pressure at the liquid spray hole 12 and the flow rate of the liquid sprayed out will be high, and the liquid spray hole 12 is more likely to be blocked, and the liquid separation component needs to withstand excessive water delivery pressure; at the same time It is necessary to reasonably arrange the number and spacing of the spray holes 12 to improve the uniformity of each spray hole 12 spraying the roller brush. If the spacing between adjacent spray holes 12 is too large, it is easy to cause insufficient spray coverage, while if the spacing between adjacent spray holes 12 is too small, the density of the spray holes 12 will be too large, resulting in excessive cross-coverage of the spray coverage of adjacent spray holes 12, which will cause problems of uneven spraying and wetting of the roller brush. Combined with the pump water flow rate used in conventional liquid separation components and the pressure range that the water supply pipeline of the liquid separation component toward the spray hole 12 can withstand, a reasonable aperture and number of the spray holes 12 are set, and the value range of a single flow area, a total flow area and the spacing between adjacent spray holes 12 with better uniformity in spraying and wetting the roller brush can be obtained. The total flow area of ​​multiple spray holes 12 is further set at 0.35mm 2 Up to 2.51mm 2 The flow area of ​​a single liquid spray hole 12 is set at 0.01mm 2 Up to 0.16mm 2 The distance between adjacent spray holes 12 is set between 6 mm and 18.6 mm, which is beneficial to further optimize the atomization effect of the spray liquid from multiple spray holes 12 and the uniform wetting effect of the spray roller brush, thereby improving the problem of water stains caused by uneven wetting of the roller brush when cleaning the surface to be cleaned, and improving the cleaning efficiency of the roller brush.

[0095] Specifically, in some embodiments, referring to Figures 1 to 4 The liquid separation housing 1 includes a main body 13 , a liquid separation member 14 and a cover body 15 .

[0096] Among them, in this embodiment, Figure 2 and Figure 3As shown, the main body 13, the liquid separator 14 and the cover 15 are arranged as a split assembly structure. The main body 13 and the cover 15 are arranged along the width direction Y, and the liquid separator 14 is arranged between the cover 15 and the main body 13. Among them, the main body 13 has a accommodating cavity 10, and the main body 13 is provided with an opening 130 connected to the accommodating cavity 10 along the width direction Y, and the liquid separator 14 is covered on the opening 130. The liquid inlet 11 is arranged on the main body 13, and the liquid spray hole 12 is arranged on the liquid separator 14. The cover 15 is connected to the main body 13 to clamp the liquid separator 14 relative to the main body 13, thereby further improving the installation stability of the liquid separator 14.

[0097] In order to improve the positioning accuracy and installation stability of the liquid separation member 14, as Figure 4 As shown, the main body 13 is located at the opening 130 and a groove 131 can be arranged around the opening 130 for the liquid dispensing member 14 to be embedded.

[0098] In some embodiments, reference Figures 1 to 3 , at least part of the liquid spray holes 12 are distributed along the length direction X. In this embodiment, all the liquid spray holes 12 are evenly distributed on the liquid separation member 14 along the length direction X. The main body 13 and the liquid separation member 14 together form a receiving chamber 10 for accommodating a liquid source. When the liquid separation shell 1 is in the working state, the liquid source is introduced into the receiving chamber 10 from the liquid inlet 11 and sprayed out from the liquid spray hole 12, thereby realizing the input and output of the liquid source of the liquid separation shell 1. After the liquid separation member 14 is installed relative to the roller brush, the actual corresponding roller brush can also be adapted and installed with the liquid separation member 14 along the length direction X, which is conducive to the liquid spray hole 12 to evenly spray liquid to the roller brush and improve the uniformity of the roller brush wetting.

[0099] In some embodiments, reference Figures 2 to 4 The cover 15 is penetrated by a jet cavity 150, and a plurality of liquid spray holes 12 are connected to the jet cavity 150 to spray liquid toward the roller brush. During the operation of the liquid separation shell 1, each liquid spray hole 12 sprays liquid toward the jet cavity 150, and at this time, the atomized liquid source can be sprayed onto the roller brush along the jet cavity 150, that is, the jet cavity 150 can guide the atomized liquid source to be evenly dispersed onto the roller brush, thereby improving the uniformity of wetting the roller brush.

[0100] The cover body 15, the main body 13 and the liquid separator 14 are all independent components. The cover body 15 can be independently disassembled and assembled relative to the main body 13 and the liquid separator 14, which is convenient for the maintenance and replacement of the cover body 15. In addition, the separately assembled cover body 15, the liquid separator 14 and the main body 13 are convenient for independent processing, thereby reducing the processing difficulty of the overall liquid separator shell 1 and improving the manufacturing yield of the liquid separator shell 1.

[0101] In addition, it is understandable that, in some embodiments, the cover 15 and the liquid separation member 14 may also be designed as an integral structure, which is beneficial to further simplify the assembly structure of the entire liquid separation housing 1 and improve the assembly efficiency of the liquid separation housing 1 .

[0102] Regarding the specific structural design of the cover body 15, in some embodiments, refer to Figures 1 to 3 There are multiple jet chambers 150, at least some of the jet chambers 150 are spaced apart from each other, and each jet chamber 150 is connected to at least one spray hole 12. Figure 3 As shown, in this embodiment, the number of the jet chambers 150 and the number of the liquid spray holes 12 are the same, that is, the plurality of jet chambers 150 are spaced apart in the length direction X, and the plurality of jet chambers 150 and the plurality of liquid spray holes 12 correspond to each other one by one. This is conducive to further optimizing the guiding effect of the jet chamber 150 for each liquid spray hole 12 and improving the uniformity of the rolling brush wetting.

[0103] Of course, it is understandable that in other embodiments, the number of the jet chambers 150 may be less than the number of the liquid spray holes 12 , that is, a design in which a plurality of liquid spray holes 12 correspond to one jet chamber 150 .

[0104] In addition, in some embodiments, there may be only one jet cavity 150 , and in this case, the plurality of liquid spray holes 12 are all connected to the same jet cavity 150 .

[0105] From the perspective of the roller brush, the liquid separation shell 1 has a liquid spraying state toward the roller brush. In this embodiment, the liquid spraying state can be a stable state in which the liquid spraying hole 12 sprays liquid toward the roller brush. When the roller brush and the liquid separation shell 1 are relatively fixedly installed, during the operation of the roller brush, when part of the bristles of the roller brush rotate toward the jet chamber 150, the jet chamber 150 actually provides a space for the bristles of the roller brush to rise. Regardless of whether the cover body 15 is in contact with the roller brush, the jet chamber 150 can ensure that the bristles toward the liquid spraying hole 12 can rise. At this time, when the liquid spraying hole 12 sprays liquid toward this part of the bristles, the liquid has a better penetration effect on the roller brush, which is conducive to improving the uniformity and wetting effect of the roller brush.

[0106] Specifically, in some embodiments, referring to 2 and Figure 4 The cover 15 includes a base 151 and a liquid separation portion 152 disposed on the base 151, and the jet chamber 150 is disposed on the base 151. Figure 4 As shown, a side of the base 151 facing away from the liquid separation member 14 is formed with an arc surface 153 that matches the cross-sectional shape of the rolling brush.

[0107] In some embodiments, after the cover 15 and the roller brush are relatively fixed, the base 151 may not be in contact with the roller brush, that is, there is a gap between the arc surface 153 and the roller brush, but it is necessary to ensure that the liquid separation portion 152 is in contact with the roller brush. Figure 4 As shown, the actual liquid separation portion 152, that is, the portion of the roller brush facing the spray chamber 150, contacts the outer edge of the spray chamber 150 when the roller brush rotates away from the opposite spray chamber 150.

[0108] It is understandable that in other embodiments, the liquid separation portion 152 can also be arranged on the arc surface 153 or other positions to ensure that after the roller brush is partially wetted, the liquid can be pressed against and dispersed by the liquid separation portion 152. For example, the arc surface 153 is provided with edges, bumps and other structures for pressing against and scraping the liquid on the roller brush, which will not be described in detail here.

[0109] In the liquid spraying state, the roller brush rotates and makes part of itself face the jet chamber 150 to receive the liquid sprayed from the jet chamber 150, thereby wetting the roller brush. Subsequently, along the rotation direction W of the roller brush, the wetted part of the roller brush is pressed and squeezed by the liquid separator 152 to disperse the liquid accumulated on the roller brush, thereby further improving the wetting uniformity of the roller brush, which is beneficial to improving the cleaning effect and efficiency of the roller brush.

[0110] In addition, in some embodiments, the curved surface 153 of the base 151 can also fit the roller brush as a whole. At this time, the jet cavity 150 provides a more prominent effect of lifting the bristles of the roller brush, and the curved surface 153 and the liquid separation portion 152 can both provide the function of pressing against the roller brush to disperse the liquid on the roller brush.

[0111] In addition, it can be understood that in some embodiments, the main body 13, the liquid separator 14 and the cover 15 can also be an integral structure. The cover 15, the liquid separator 14 and the main body 13 of the integral structure simplify the assembly process of the main body 13 and the liquid separator 14 compared with the cover 15, the liquid separator 14 and the main body 13 of the separate structure, which is conducive to improving the production efficiency of the overall liquid separator housing 1.

[0112] In some embodiments, the number a of the liquid spray holes 12 satisfies: 15≤a≤33. That is, a can be any one of 15 to 33 or a range of any two of them. Setting the number of liquid spray holes 12 between 15 and 33 is conducive to further optimizing the atomization effect of the liquid sprayed by the multiple liquid spray holes 12 and the uniform wetting effect of the spray roller brush, thereby improving the cleaning effect and cleaning efficiency of the roller brush.

[0113] Optionally, in some embodiments, the total flow area S of the plurality of liquid spray holes 12 satisfies: 0.35 mm 2 ≤S≤1.84mm 2 . That is, S can be 0.35mm 2 Up to 1.84mm 2 The range value consisting of any one or any two of .

[0114] In some embodiments, the flow area S1 of a single liquid spray hole 12 satisfies: 0.017 mm 2 ≤S1≤0.071mm 2 That is, S1 can be 0.017mm 2 Up to 0.071mm 2The range value consisting of any one or any two of .

[0115] In some embodiments, the distance D between adjacent liquid spray holes 12 satisfies: 6.5 mm≤D≤14 mm, that is, D can be a range of any one of 6.5 mm to 14 mm or any two of them.

[0116] In some embodiments, the number a of the liquid spray holes 12 satisfies: 20≤a≤30. That is, a can be a range value consisting of any one of 20 to 30 or any two of them.

[0117] The total flow area of ​​the plurality of liquid spray holes 12 is further set to 0.35 mm 2 Up to 1.84mm 2 The flow area of ​​a single spray hole 12 is set at 0.017mm 2 Up to 0.071mm 2 The distance between adjacent spray holes 12 is set between 6.5 mm and 14 mm, and the number of spray holes 12 is set between 20 and 30, which is beneficial to further optimize the atomization effect of the spray liquid from multiple spray holes 12 and the uniform wetting effect of the spray roller brush, thereby improving the cleaning effect and cleaning efficiency of the roller brush.

[0118] In some embodiments, in the liquid spraying state, the initial velocity V0 of the liquid spraying flow from the liquid spraying hole 12 satisfies: 1 m / s≤V0≤5 m / s, that is, V0 can be any one of 1 m / s to 5 m / s or any two of the range values.

[0119] In the spraying state, the speed of the liquid flow sprayed from the spray hole 12 can reach 1m / s to 5m / s, which is beneficial to increase the spray distance of the liquid flow sprayed from the spray port and the penetration ability of the wet roller brush, thereby improving the efficiency of the wet roller brush to improve the cleaning effect and cleaning efficiency of the roller brush.

[0120] In some embodiments, reference Figure 2 , the dimension L of the liquid separator 14 in the length direction X satisfies: 200mm≤L≤280mm. That is, L can be any one of 200mm to 280mm or a range of any two. By setting the length dimension of the liquid separator 14 between 200mm and 280mm, so as to adapt to the length dimension of the roller brush, it is beneficial for the liquid spraying holes 12 arranged on the liquid separator 14 to evenly spray liquid to the roller brush, thereby improving the uniformity of the roller brush wetting.

[0121] The embodiment of the present application also discloses a liquid separation component. The liquid separation component includes a liquid separation shell 1. The liquid separation shell 1 has a accommodating chamber 10, and the liquid separation shell 1 is provided with a liquid inlet 11 connected to the accommodating chamber 10 and a plurality of liquid spray holes 12. Among them, in the present embodiment, the liquid separation shell 1 has two sides arranged oppositely in the width direction Y, the liquid inlet 11 is arranged on one side of the liquid separation shell 1 in the width direction Y, and the plurality of liquid spray holes 12 are arranged on the other side of the liquid separation shell 1 in the width direction Y. The liquid inlet 11 and the liquid spray holes 12 are distributed on both sides of the liquid separation shell 1 in the width direction Y to provide sufficient space for the external infusion pipeline for the liquid inlet 11 to avoid affecting the arrangement and liquid spraying of the liquid spray holes 12. It can be understood that the liquid separation shell 1 is provided with a side of the liquid spray hole 12 to be arranged toward the roller brush, so that the liquid spray hole 12 can spray liquid toward the roller brush.

[0122] The total flow area of ​​the plurality of liquid spray holes 12 is smaller than the flow area of ​​the liquid inlet 11 .

[0123] The total flow area S of the plurality of liquid spray holes 12 satisfies: 0.35 mm 2 ≤S≤2.51mm 2, that is, the value of S can be 0.35, 0.36, 0.37, 0.38, 0.39, 0.40, 0.41, 0.42, 0.43, 0.44, 0.45, 0.46, 0.47, 0.48, 0.49, 0.50, 0.51, 0.52, 0.53, 0.54, 0.55, 0.56, 0.57, 0 .58, 0.59, 0.60, 0.61, 0.62, 0.63, 0.64, 0.65, 0.66, 0.67, 0.68, 0.69, 0.70, 0.71, 0.72, 0.73, 0.74, 0.75, 0.76, 0.77, 0.78, 0.79, 0.80, 0.81, 0.82, 0 .83, 0.84, 0.85, 0.86, 0.87, 0.88, 0.89, 0.90, 0.91, 0.92, 0.93, 0.94, 0.95, 0.96, 0.97, 0.98, 0.99, 1.00, 1.01, 1.02, 1.03, 1.04, 1.05, 1.06, 1.07, 1 .08, 1.09, 1.10, 1.11, 1.12, 1.13, 1.14, 1.15, 1.16, 1.17, 1.18, 1.19, 1.20, 1.21, 1.22, 1.23, 1.24, 1.25, 1.26, 1.27, 1.28, 1.29, 1.30, 1.31, 1.32, 1 .33, 1.34, 1.35, 1.36, 1.37, 1.38, 1.39, 1.40, 1.41, 1.42, 1.43, 1.44, 1.45, 1.46, 1.47, 1.48, 1.49, 1.50, 1.51, 1.52, 1.53, 1.54, 1.55, 1.56, 1.57, 1 .58, 1.59, 1.60, 1.61, 1.62, 1.63, 1.64, 1.65, 1.66, 1.67, 1.68, 1.69, 1.70, 1.71, 1.72, 1.73, 1.74, 1.75, 1.76, 1.77, 1.78, 1.79, 1.80, 1.81, 1.82, 1 .83, 1.84, 1.85, 1.86, 1.87, 1.88, 1.89, 1.90, 1.91, 1.92, 1.93, 1.94, 1.95, 1.96, 1.97, 1.98, 1.99, 2.00, 2.01, 2.02, 2.03, 2.04, 2.05, 2.06, 2.07, 2 .08, 2.09, 2.10, 2.11, 2.12, 2.13, 2.14, 2.15, 2.16, 2.17, 2.18, 2.19, 2.20, 2.21, 2.22, 2.23, 2.24, 2.25, 2.26, 2.27, 2.28, 2.29, 2.30, 2.31, 2.32, 2.33, 2.34, 2.35, 2.36, 2.37, 2.38, 2.39, 2.40, 2.41, 2.42, 2.43, 2.44, 2.45, 2.46, 2.47, 2.48, 2.49, 2.50, 2.51, or a range of any two of them. .

[0124] The flow area S1 of a single spray hole 12 satisfies: 0.01mm 2 ≤S1≤0.16mm 2 That is, the value of S1 can be any one of 0.01, 0.02, 0.03, 0.04, 0.05, 0.06, 0.07, 0.08, 0.09, 0.10, 0.11, 0.12, 0.13, 0.14, 0.15, and 0.16, or a range of any two of them.

[0125] The number a of the liquid spray holes 12 satisfies: 15≤a≤33, that is, a can be any one of 15, 16, 17, 18, 19, 20, 21, 22, 23, 24, 25, 26, 27, 28, 29, 30, 31, 32, 33 or a range value consisting of any two of them.

[0126] It should be noted that, in the present embodiment, the flow cross-sectional shapes of the liquid inlet 11 and the liquid spray hole 12 are both circular in design, that is, the flow area S1 of a single liquid spray hole 12 can be directly calculated by measuring the radial dimension of the liquid spray hole 12. After calculating the flow area S1 of a single liquid spray hole 12, the total flow area S of multiple liquid spray holes 12 can be obtained by multiplying the design number of liquid spray holes 12.

[0127] Similarly, the flow area of ​​the liquid inlet 11 can also be directly calculated by measuring the radial dimension of the liquid inlet 11, which will not be described in detail here.

[0128] In other embodiments, the flow cross-section of the liquid inlet 11 and the liquid spray hole 12 may also be a regular polygon such as a triangle, rectangle, ellipse, hexagon, etc., and the area calculation of the corresponding flow cross-section may be calculated by measuring the required size parameters using the corresponding polygon area calculation formula. In addition, in other embodiments, the flow cross-section of the liquid inlet 11 and the liquid spray hole 12 may also be an irregular shape, and the area of ​​the irregular shape may be calculated by scanning the flow cross-section of the liquid inlet 11 and the liquid spray hole 12 through a computer, which will not be described in detail here.

[0129] When the liquid separation component is used to spray liquid toward the roller brush, the liquid source is transported from the liquid inlet 11 to the accommodating chamber 10. Since the total flow area of ​​the multiple liquid spray holes 12 is smaller than the flow area of ​​the liquid inlet 11, a liquid spray pressure is formed at the liquid spray holes 12, which is beneficial to increase the spray speed of the liquid spray holes 12 and atomize the liquid sprayed from the liquid spray holes 12, thereby expanding the spray range of the liquid spray holes 12 toward the roller brush and enhancing the wetting and penetration effect on the roller brush. The wetted roller brush rolls and cleans the surface to be cleaned, thereby achieving a quick cleaning function.

[0130] The liquid spray hole 12 actually needs to be set on the surface opposite to the liquid separation component and the roller brush. The length of the liquid separation component needs to be adapted to the length of the roller brush. When setting the size of each liquid spray hole 12, if the opening of the liquid spray hole 12 is too large, it is easy to cause the flow area of ​​the liquid spray hole 12 and the total flow area of ​​all the liquid spray holes 12 to be too large. At this time, the liquid spray pressure at the liquid spray hole 12 and the flow rate of the liquid sprayed out will decrease, and the actual spraying and wetting of the roller brush by the liquid spray hole 12 will be reduced. The atomization effect and uniformity of the liquid spray hole 12 will be reduced. If the opening of the liquid spray hole 12 is too small, it is easy to cause the flow area of ​​the liquid spray hole 12 and the total flow area of ​​all the liquid spray holes 12 to be too small. At this time, the liquid spray pressure at the liquid spray hole 12 and the flow rate of the liquid sprayed out will be high, and the liquid spray hole 12 is more likely to be blocked, and the liquid separation component needs to withstand excessive water delivery pressure; at the same time It is necessary to reasonably arrange the number and spacing of the spray holes 12 to improve the uniformity of each spray hole 12 spraying the roller brush. If the spacing between adjacent spray holes 12 is too large, it is easy to cause insufficient spray coverage, while if the spacing between adjacent spray holes 12 is too small, the density of the spray holes 12 will be too large, resulting in excessive cross-coverage of the spray coverage of adjacent spray holes 12, which will cause problems of uneven spraying and wetting of the roller brush. Combined with the pump water flow rate used in conventional liquid separation components and the pressure range that the water supply pipeline of the liquid separation component toward the spray hole 12 can withstand, a reasonable aperture and number of the spray holes 12 are set, and the value range of a single flow area, a total flow area and the spacing between adjacent spray holes 12 with better uniformity in spraying and wetting the roller brush can be obtained. The total flow area of ​​multiple spray holes 12 is further set at 0.35mm 2 Up to 2.51mm 2 The flow area of ​​a single liquid spray hole 12 is set at 0.01mm 2 Up to 0.16mm 2 The number of the liquid spray holes 12 is set between 15 and 33, which is beneficial to further optimize the atomization effect of the liquid sprayed by the multiple liquid spray holes 12 and the uniform wetting effect of the spray roller brush, thereby improving the problem of water stains caused by uneven wetting of the roller brush when cleaning the surface to be cleaned, and improving the cleaning efficiency of the roller brush.

[0131] Specifically, in some embodiments, referring to Figures 1 to 4 The liquid separation housing 1 includes a main body 13 , a liquid separation member 14 and a cover body 15 .

[0132] Among them, in this embodiment, Figure 2 and Figure 3 As shown, the main body 13, the liquid separator 14 and the cover 15 are arranged as a split assembly structure. The main body 13 and the cover 15 are arranged along the width direction Y, and the liquid separator 14 is arranged between the cover 15 and the main body 13. Among them, the main body 13 has a accommodating cavity 10, and the main body 13 is provided with an opening 130 connected to the accommodating cavity 10 along the width direction Y, and the liquid separator 14 is covered on the opening 130. The liquid inlet 11 is arranged on the main body 13, and the liquid spray hole 12 is arranged on the liquid separator 14. The cover 15 is connected to the main body 13 to clamp the liquid separator 14 relative to the main body 13, thereby further improving the installation stability of the liquid separator 14.

[0133] In order to improve the positioning accuracy and installation stability of the liquid separation member 14, as Figure 4 As shown, the main body 13 is located at the opening 130 and a groove 131 can be arranged around the opening 130 for the liquid dispensing member 14 to be embedded.

[0134] In some embodiments, reference Figures 1 to 3 , at least part of the liquid spray holes 12 are distributed along the length direction X. In this embodiment, all the liquid spray holes 12 are evenly distributed on the liquid separation member 14 along the length direction X. The main body 13 and the liquid separation member 14 together form a receiving chamber 10 for accommodating a liquid source. When the liquid separation shell 1 is in the working state, the liquid source is introduced into the receiving chamber 10 from the liquid inlet 11 and sprayed out from the liquid spray hole 12, thereby realizing the input and output of the liquid source of the liquid separation shell 1. After the liquid separation member 14 is installed relative to the roller brush, the actual corresponding roller brush can also be adapted and installed with the liquid separation member 14 along the length direction X, which is conducive to the liquid spray hole 12 to evenly spray liquid to the roller brush and improve the uniformity of the roller brush wetting.

[0135] In some embodiments, reference Figures 2 to 4 The cover 15 is penetrated by a jet cavity 150, and a plurality of liquid spray holes 12 are connected to the jet cavity 150 to spray liquid toward the roller brush. During the operation of the liquid separation shell 1, each liquid spray hole 12 sprays liquid toward the jet cavity 150, and at this time, the atomized liquid source can be sprayed onto the roller brush along the jet cavity 150, that is, the jet cavity 150 can guide the atomized liquid source to be evenly dispersed onto the roller brush, thereby improving the uniformity of wetting the roller brush.

[0136] The cover body 15, the main body 13 and the liquid separator 14 are all independent components. The cover body 15 can be independently disassembled and assembled relative to the main body 13 and the liquid separator 14, which is convenient for the maintenance and replacement of the cover body 15. In addition, the separately assembled cover body 15, the liquid separator 14 and the main body 13 are convenient for independent processing, thereby reducing the processing difficulty of the overall liquid separator shell 1 and improving the manufacturing yield of the liquid separator shell 1.

[0137] In addition, it is understandable that, in some embodiments, the cover 15 and the liquid separation member 14 may also be designed as an integral structure, which is beneficial to further simplify the assembly structure of the entire liquid separation housing 1 and improve the assembly efficiency of the liquid separation housing 1 .

[0138] Regarding the specific structural design of the cover body 15, in some embodiments, refer to Figures 1 to 3 There are multiple jet chambers 150, at least some of the jet chambers 150 are spaced apart from each other, and each jet chamber 150 is connected to at least one spray hole 12. Figure 3 As shown, in this embodiment, the number of the jet chambers 150 and the number of the liquid spray holes 12 are the same, that is, the plurality of jet chambers 150 are spaced apart in the length direction X, and the plurality of jet chambers 150 and the plurality of liquid spray holes 12 correspond to each other one by one. This is conducive to further optimizing the guiding effect of the jet chamber 150 for each liquid spray hole 12 and improving the uniformity of the rolling brush wetting.

[0139] Of course, it is understandable that in other embodiments, the number of the jet chambers 150 may be less than the number of the liquid spray holes 12 , that is, a design in which a plurality of liquid spray holes 12 correspond to one jet chamber 150 .

[0140] In addition, in some embodiments, there may be only one jet cavity 150 , and in this case, the plurality of liquid spray holes 12 are all connected to the same jet cavity 150 .

[0141] From the perspective of the roller brush, the liquid separation shell 1 has a liquid spraying state toward the roller brush. In this embodiment, the liquid spraying state can be a stable state in which the liquid spraying hole 12 sprays liquid toward the roller brush. When the roller brush and the liquid separation shell 1 are relatively fixedly installed, during the operation of the roller brush, when part of the bristles of the roller brush rotate toward the jet chamber 150, the jet chamber 150 actually provides a space for the bristles of the roller brush to rise. Regardless of whether the cover body 15 is in contact with the roller brush, the jet chamber 150 can ensure that the bristles toward the liquid spraying hole 12 can rise. At this time, when the liquid spraying hole 12 sprays liquid toward this part of the bristles, the liquid has a better penetration effect on the roller brush, which is conducive to improving the uniformity and wetting effect of the roller brush.

[0142] Specifically, in some embodiments, referring to 2 and Figure 4 The cover 15 includes a base 151 and a liquid separation portion 152 disposed on the base 151, and the jet chamber 150 is disposed on the base 151. Figure 4 As shown, a side of the base 151 facing away from the liquid separation member 14 is formed with an arc surface 153 that matches the cross-sectional shape of the rolling brush.

[0143] In some embodiments, after the cover 15 and the roller brush are relatively fixed, the base 151 may not be in contact with the roller brush, that is, there is a gap between the arc surface 153 and the roller brush, but it is necessary to ensure that the liquid separation portion 152 is in contact with the roller brush. Figure 4As shown, the actual liquid separation portion 152, that is, the portion of the roller brush facing the spray chamber 150, contacts the outer edge of the spray chamber 150 when the roller brush rotates away from the opposite spray chamber 150.

[0144] It is understandable that in other embodiments, the liquid separation portion 152 can also be arranged at the arc surface 153 or other positions to ensure that after the roller brush is partially wetted, the liquid can be pressed against and dispersed by the liquid separation portion 152. For example, the arc surface 153 is provided with edges, bumps and other structures for pressing against and scraping the liquid on the roller brush, which will not be described in detail.

[0145] In the liquid spraying state, the roller brush rotates and makes part of itself face the jet chamber 150 to receive the liquid sprayed from the jet chamber 150, thereby wetting the roller brush. Subsequently, the wetted part of the roller brush is pressed and squeezed by the liquid separator 152 to disperse the liquid accumulated on the roller brush, thereby further improving the wetting uniformity of the roller brush, which is beneficial to improving the cleaning effect and efficiency of the roller brush.

[0146] In addition, in some embodiments, the curved surface 153 of the base 151 can also fit the roller brush as a whole. At this time, from the perspective of the roller brush, the jet cavity 150 can provide a more prominent effect of lifting the bristles of the roller brush, and the curved surface 153 and the liquid separation portion 152 can both provide the function of pressing against the roller brush to disperse the liquid on the roller brush.

[0147] In addition, it can be understood that in some embodiments, the main body 13, the liquid separator 14 and the cover 15 can also be an integral structure. The cover 15, the liquid separator 14 and the main body 13 of the integral structure simplify the assembly process of the main body 13 and the liquid separator 14 compared with the cover 15, the liquid separator 14 and the main body 13 of the separate structure, which is conducive to improving the production efficiency of the overall liquid separator housing 1.

[0148] Optionally, in some embodiments, the total flow area S of the plurality of liquid spray holes 12 satisfies: 0.35 mm 2 ≤S≤1.84mm 2 . That is, S can be 0.35mm 2 Up to 1.84mm 2 The range value consisting of any one or any two of .

[0149] In some embodiments, the flow area S1 of a single liquid spray hole 12 satisfies: 0.017 mm 2 ≤S1≤0.071mm 2 That is, S1 can be 0.017mm 2 Up to 0.071mm 2 The range value consisting of any one or any two of .

[0150] In some embodiments, the number a of the liquid spray holes 12 satisfies: 20≤a≤30. That is, a can be a range value consisting of any one of 20 to 30 or any two of them.

[0151] The total flow area of ​​the plurality of liquid spray holes 12 is further set to 0.35 mm 2 Up to 1.84mm 2 The flow area of ​​a single spray hole 12 is set at 0.017mm 2 Up to 0.071mm 2 Setting the number of the liquid spray holes 12 between 20 and 30 is beneficial to further optimize the atomization effect of the liquid sprayed by the multiple liquid spray holes 12 and the uniform wetting effect of the spray roller brush, thereby improving the cleaning effect and cleaning efficiency of the roller brush.

[0152] In some embodiments, in the liquid spraying state, the initial velocity V0 of the liquid spraying flow from the liquid spraying hole 12 satisfies: 1 m / s≤V0≤5 m / s, that is, V0 can be any one of 1 m / s to 5 m / s or any two of the range values.

[0153] In the spraying state, the speed of the liquid flow sprayed from the spray hole 12 can reach 1m / s to 5m / s, which is beneficial to increase the spray distance of the liquid flow sprayed from the spray port and the penetration ability of the wet roller brush, thereby improving the efficiency of the wet roller brush to improve the cleaning effect and cleaning efficiency of the roller brush.

[0154] In some embodiments, reference Figure 2 , the dimension L of the liquid separator 14 in the length direction X satisfies: 200mm≤L≤280mm. That is, L can be any one of 200mm to 280mm or a range of any two. By setting the length dimension of the liquid separator 14 between 200mm and 280mm, so as to adapt to the length dimension of the roller brush, it is beneficial for the liquid spraying holes 12 arranged on the liquid separator 14 to evenly spray liquid to the roller brush, thereby improving the uniformity of the roller brush wetting.

[0155] The embodiment of the present application also discloses a liquid separation component. The liquid separation component includes a liquid separation shell 1. The liquid separation shell 1 has a accommodating chamber 10, and the liquid separation shell 1 is provided with a liquid inlet 11 connected to the accommodating chamber 10 and a plurality of liquid spray holes 12. Among them, in the present embodiment, the liquid separation shell 1 has two sides arranged oppositely in the width direction Y, the liquid inlet 11 is arranged on one side of the liquid separation shell 1 in the width direction Y, and the plurality of liquid spray holes 12 are arranged on the other side of the liquid separation shell 1 in the width direction Y. The liquid inlet 11 and the liquid spray holes 12 are distributed on both sides of the liquid separation shell 1 in the width direction Y to provide sufficient space for the external infusion pipeline for the liquid inlet 11 to avoid affecting the arrangement and liquid spraying of the liquid spray holes 12. It can be understood that the liquid separation shell 1 is provided with a side of the liquid spray hole 12 to be arranged toward the roller brush, so that the liquid spray hole 12 can spray liquid toward the roller brush.

[0156] The total flow area of ​​the plurality of liquid spray holes 12 is smaller than the flow area of ​​the liquid inlet 11 .

[0157] The total flow area S of the plurality of liquid spray holes 12 satisfies: 0.35 mm 2 ≤S≤2.51mm 2, that is, the value of S can be 0.35, 0.36, 0.37, 0.38, 0.39, 0.40, 0.41, 0.42, 0.43, 0.44, 0.45, 0.46, 0.47, 0.48, 0.49, 0.50, 0.51, 0.52, 0.53, 0.54, 0.55, 0.56, 0.57, 0 .58, 0.59, 0.60, 0.61, 0.62, 0.63, 0.64, 0.65, 0.66, 0.67, 0.68, 0.69, 0.70, 0.71, 0.72, 0.73, 0.74, 0.75, 0.76, 0.77, 0.78, 0.79, 0.80, 0.81, 0.82, 0 .83, 0.84, 0.85, 0.86, 0.87, 0.88, 0.89, 0.90, 0.91, 0.92, 0.93, 0.94, 0.95, 0.96, 0.97, 0.98, 0.99, 1.00, 1.01, 1.02, 1.03, 1.04, 1.05, 1.06, 1.07, 1 .08, 1.09, 1.10, 1.11, 1.12, 1.13, 1.14, 1.15, 1.16, 1.17, 1.18, 1.19, 1.20, 1.21, 1.22, 1.23, 1.24, 1.25, 1.26, 1.27, 1.28, 1.29, 1.30, 1.31, 1.32, 1 .33, 1.34, 1.35, 1.36, 1.37, 1.38, 1.39, 1.40, 1.41, 1.42, 1.43, 1.44, 1.45, 1.46, 1.47, 1.48, 1.49, 1.50, 1.51, 1.52, 1.53, 1.54, 1.55, 1.56, 1.57, 1 .58, 1.59, 1.60, 1.61, 1.62, 1.63, 1.64, 1.65, 1.66, 1.67, 1.68, 1.69, 1.70, 1.71, 1.72, 1.73, 1.74, 1.75, 1.76, 1.77, 1.78, 1.79, 1.80, 1.81, 1.82, 1 .83, 1.84, 1.85, 1.86, 1.87, 1.88, 1.89, 1.90, 1.91, 1.92, 1.93, 1.94, 1.95, 1.96, 1.97, 1.98, 1.99, 2.00, 2.01, 2.02, 2.03, 2.04, 2.05, 2.06, 2.07, 2 .08, 2.09, 2.10, 2.11, 2.12, 2.13, 2.14, 2.15, 2.16, 2.17, 2.18, 2.19, 2.20, 2.21, 2.22, 2.23, 2.24, 2.25, 2.26, 2.27, 2.28, 2.29, 2.30, 2.31, 2.32, 2.33, 2.34, 2.35, 2.36, 2.37, 2.38, 2.39, 2.40, 2.41, 2.42, 2.43, 2.44, 2.45, 2.46, 2.47, 2.48, 2.49, 2.50, 2.51, or a range of any two of them. .

[0158] The distance D between adjacent spray holes 12 satisfies: 6 mm ≤ D ≤ 18.6 mm, that is, the value of D can be 6.0, 6.1, 6.2, 6.3, 6.4, 6.5, 6.6, 6.7, 6.8, 6.9, 7.0, 7.1, 7.2, 7.3, 7.4, 7.5, 7.6, 7.7, 7.8, 7.9, 8.0, 8.1, 8.2, 8.3, 8.4, 8.5, 8.6, 8.7, 8.8, 8.9, 9.0, 9.1 , 9.2, 9.3, 9.4, 9.5, 9.6, 9.7, 9.8, 9.9, 10.0, 10.1, 10.2, 10.3, 10.4, 10.5, 10.6, 10.7, 10.8, 10.9, 11.0, 11.1, 11.2, 11.3, 11.4, 11.5, 11.6, 11.7, 11.8, 11.9, 12.0, 12.1, 12.2, 12.3, 12.4, 12.5 , 12.6, 12.7, 12.8, 12.9, 13.0, 13.1, 13.2, 13.3, 13.4, 13.5, 13.6, 13.7, 13.8, 13.9, 14.0, 14.1, 14.2, 14.3, 14.4, 14.5, 14.6, 14.7, 14.8, 14.9, 15.0, 15.1, 15.2, 15.3, 15.4, 15.5, 15.6, 15.7, 1 The range value consists of any one of 18.0, 18.1, 18.2, 18.3, 18.4, 18.5, and 18.6, or any two of the following.

[0159] The number a of the liquid spray holes 12 satisfies: 15≤a≤33, that is, a can be any one of 15, 16, 17, 18, 19, 20, 21, 22, 23, 24, 25, 26, 27, 28, 29, 30, 31, 32, 33 or a range value consisting of any two of them.

[0160] It should be noted that in this embodiment, the flow cross-sectional shapes of the liquid inlet 11 and the liquid spray hole 12 are both circular in design, that is, the flow area S1 of a single liquid spray hole 12 can be directly calculated by measuring the radial dimension d of the liquid spray hole 12, specifically S1 = πd 2 / 4, after calculating the flow area S1 of a single spray hole 12, the total flow area S of multiple spray holes 12 can be obtained by multiplying the designed number of spray holes 12. The distance D between adjacent spray holes 12 can be directly measured by a ruler.

[0161] Similarly, the flow area of ​​the liquid inlet 11 can also be directly calculated by measuring the radial dimension of the liquid inlet 11, which will not be described in detail here.

[0162] In other embodiments, the flow cross-section of the liquid inlet 11 and the liquid spray hole 12 may also be a regular polygon such as a triangle or a rectangle, and the area calculation of the corresponding flow cross-section may be calculated by measuring the required size parameters using the corresponding polygon area calculation formula. In addition, in other embodiments, the flow cross-section of the liquid inlet 11 and the liquid spray hole 12 may also be an irregular shape, and the area of ​​the irregular shape may be calculated by scanning the flow cross-section of the liquid inlet 11 and the liquid spray hole 12 through a computer, which will not be described in detail here.

[0163] When the liquid separation component is used to spray liquid toward the roller brush, the liquid source is transported from the liquid inlet 11 to the accommodating chamber 10. Since the total flow area of ​​the multiple liquid spray holes 12 is smaller than the flow area of ​​the liquid inlet 11, a liquid spray pressure is formed at the liquid spray holes 12, which is beneficial to increase the spray speed of the liquid spray holes 12 and atomize the liquid sprayed from the liquid spray holes 12, thereby expanding the spray range of the liquid spray holes 12 toward the roller brush and enhancing the wetting and penetration effect on the roller brush. The wetted roller brush rolls and cleans the surface to be cleaned, thereby achieving a quick cleaning function.

[0164] The liquid spray hole 12 actually needs to be set on the surface opposite to the liquid separation component and the roller brush. The length of the liquid separation component needs to be adapted to the length of the roller brush. When setting the size of each liquid spray hole 12, if the opening of the liquid spray hole 12 is too large, it is easy to cause the flow area of ​​the liquid spray hole 12 and the total flow area of ​​all the liquid spray holes 12 to be too large. At this time, the liquid spray pressure at the liquid spray hole 12 and the flow rate of the liquid sprayed out will decrease, and the actual spraying and wetting of the roller brush by the liquid spray hole 12 will be reduced. The atomization effect and uniformity of the liquid spray hole 12 will be reduced. If the opening of the liquid spray hole 12 is too small, it is easy to cause the flow area of ​​the liquid spray hole 12 and the total flow area of ​​all the liquid spray holes 12 to be too small. At this time, the liquid spray pressure at the liquid spray hole 12 and the flow rate of the liquid sprayed out will be high, and the liquid spray hole 12 is more likely to be blocked, and the liquid separation component needs to withstand excessive water delivery pressure; at the same time It is necessary to reasonably arrange the number and spacing of the spray holes 12 to improve the uniformity of each spray hole 12 spraying the roller brush. If the spacing between adjacent spray holes 12 is too large, it is easy to cause insufficient spray coverage, while if the spacing between adjacent spray holes 12 is too small, the density of the spray holes 12 will be too large, resulting in excessive cross-coverage of the spray coverage of adjacent spray holes 12, which will cause problems of uneven spraying and wetting of the roller brush. Combined with the pump water flow rate used in conventional liquid separation components and the pressure range that the water supply pipeline of the liquid separation component toward the spray hole 12 can withstand, a reasonable aperture and number of the spray holes 12 are set, and the value range of a single flow area, a total flow area and the spacing between adjacent spray holes 12 with better uniformity in spraying and wetting the roller brush can be obtained. The total flow area of ​​multiple spray holes 12 is further set at 0.35mm 2 Up to 2.51mm 2 Setting the distance between adjacent spray holes 12 between 6 mm and 18.6 mm, and setting the number of spray holes 12 between 15 and 33, is beneficial to further optimize the atomization effect of the spray liquid from multiple spray holes 12 and the uniform wetting effect of the spray roller brush, thereby improving the problem of water stains caused by uneven wetting of the roller brush when cleaning the surface to be cleaned, and improving the cleaning efficiency of the roller brush.

[0165] Specifically, in some embodiments, referring to Figures 1 to 4 The liquid separation housing 1 includes a main body 13 , a liquid separation member 14 and a cover body 15 .

[0166] Among them, in this embodiment, Figure 2 and Figure 3As shown, the main body 13, the liquid separator 14 and the cover 15 are arranged as a split assembly structure. The main body 13 and the cover 15 are arranged along the width direction Y, and the liquid separator 14 is arranged between the cover 15 and the main body 13. Among them, the main body 13 has a accommodating cavity 10, and the main body 13 is provided with an opening 130 connected to the accommodating cavity 10 along the width direction Y, and the liquid separator 14 is covered on the opening 130. The liquid inlet 11 is arranged on the main body 13, and the liquid spray hole 12 is arranged on the liquid separator 14. The cover 15 is connected to the main body 13 to clamp the liquid separator 14 relative to the main body 13, thereby further improving the installation stability of the liquid separator 14.

[0167] In order to improve the positioning accuracy and installation stability of the liquid separation member 14, as Figure 4 As shown, the main body 13 is located at the opening 130 and a groove 131 can be arranged around the opening 130 for the liquid dispensing member 14 to be embedded.

[0168] In some embodiments, reference Figures 1 to 3 , at least part of the liquid spray holes 12 are distributed along the length direction X. In this embodiment, all the liquid spray holes 12 are evenly distributed on the liquid separation member 14 along the length direction X. The main body 13 and the liquid separation member 14 together form a receiving chamber 10 for accommodating a liquid source. When the liquid separation shell 1 is in the working state, the liquid source is introduced into the receiving chamber 10 from the liquid inlet 11 and sprayed out from the liquid spray hole 12, thereby realizing the input and output of the liquid source of the liquid separation shell 1. After the liquid separation member 14 is installed relative to the roller brush, the actual corresponding roller brush can also be adapted and installed with the liquid separation member 14 along the length direction X, which is conducive to the liquid spray hole 12 to evenly spray liquid to the roller brush and improve the uniformity of the roller brush wetting.

[0169] In some embodiments, reference Figures 2 to 4 The cover 15 is penetrated by a jet cavity 150, and a plurality of liquid spray holes 12 are connected to the jet cavity 150 to spray liquid toward the roller brush. During the operation of the liquid separation shell 1, each liquid spray hole 12 sprays liquid toward the jet cavity 150, and at this time, the atomized liquid source can be sprayed onto the roller brush along the jet cavity 150, that is, the jet cavity 150 can guide the atomized liquid source to be evenly dispersed onto the roller brush, thereby improving the uniformity of wetting the roller brush.

[0170] The cover body 15, the main body 13 and the liquid separator 14 are all independent components. The cover body 15 can be independently disassembled and assembled relative to the main body 13 and the liquid separator 14, which is convenient for the maintenance and replacement of the cover body 15. In addition, the separately assembled cover body 15, the liquid separator 14 and the main body 13 are convenient for independent processing, thereby reducing the processing difficulty of the overall liquid separator shell 1 and improving the manufacturing yield of the liquid separator shell 1.

[0171] In addition, it is understandable that, in some embodiments, the cover 15 and the liquid separation member 14 may also be designed as an integral structure, which is beneficial to further simplify the assembly structure of the entire liquid separation housing 1 and improve the assembly efficiency of the liquid separation housing 1 .

[0172] Regarding the specific structural design of the cover body 15, in some embodiments, refer to Figures 1 to 3 There are multiple jet chambers 150, at least some of the jet chambers 150 are spaced apart from each other, and each jet chamber 150 is connected to at least one spray hole 12. Figure 3 As shown, in this embodiment, the number of the jet chambers 150 and the number of the liquid spray holes 12 are the same, that is, the plurality of jet chambers 150 are spaced apart in the length direction X, and the plurality of jet chambers 150 and the plurality of liquid spray holes 12 correspond to each other one by one. This is conducive to further optimizing the guiding effect of the jet chamber 150 for each liquid spray hole 12 and improving the uniformity of the rolling brush wetting.

[0173] Of course, it is understandable that in other embodiments, the number of the jet chambers 150 may be less than the number of the liquid spray holes 12 , that is, a design in which a plurality of liquid spray holes 12 correspond to one jet chamber 150 .

[0174] In addition, in some embodiments, there may be only one jet cavity 150 , and in this case, the plurality of liquid spray holes 12 are all connected to the same jet cavity 150 .

[0175] From the perspective of the roller brush, the liquid separation shell 1 has a liquid spraying state toward the roller brush. In this embodiment, the liquid spraying state can be a stable state in which the liquid spraying hole 12 sprays liquid toward the roller brush. When the roller brush and the liquid separation shell 1 are relatively fixedly installed, during the operation of the roller brush, when part of the bristles of the roller brush rotate toward the jet chamber 150, the jet chamber 150 actually provides a space for the bristles of the roller brush to rise. Regardless of whether the cover body 15 is in contact with the roller brush, the jet chamber 150 can ensure that the bristles toward the liquid spraying hole 12 can rise. At this time, when the liquid spraying hole 12 sprays liquid toward this part of the bristles, the liquid has a better penetration effect on the roller brush, which is conducive to improving the uniformity and wetting effect of the roller brush.

[0176] Specifically, in some embodiments, referring to 2 and Figure 4 The cover 15 includes a base 151 and a liquid separation portion 152 disposed on the base 151, and the jet chamber 150 is disposed on the base 151. Figure 4 As shown, a curved surface 153 matching the cross-sectional shape of the rolling brush is formed on the side of the base 151 facing away from the liquid separation member 14 .

[0177] In some embodiments, after the cover 15 and the roller brush are relatively fixed, the base 151 may not be in contact with the roller brush, that is, there is a gap between the arc surface 153 and the roller brush, but it is necessary to ensure that the liquid separation portion 152 is in contact with the roller brush. Figure 4 As shown, the actual liquid separation portion 152, that is, the portion of the roller brush facing the spray chamber 150, contacts the outer edge of the spray chamber 150 when the roller brush rotates away from the opposite spray chamber 150.

[0178] It is understandable that in other embodiments, the liquid separation portion 152 can also be arranged at the arc surface 153 or other positions to ensure that after the roller brush is partially wetted, the liquid can be pressed against and dispersed by the liquid separation portion 152. For example, the arc surface 153 is provided with edges, bumps and other structures for pressing against and scraping the liquid on the roller brush, which will not be described in detail.

[0179] In the liquid spraying state, the roller brush rotates and makes part of itself face the jet chamber 150 to receive the liquid sprayed from the jet chamber 150, thereby wetting the roller brush. Subsequently, the wetted part of the roller brush is pressed and squeezed by the liquid separator 152 to disperse the liquid accumulated on the roller brush, thereby further improving the wetting uniformity of the roller brush, which is beneficial to improving the cleaning effect and efficiency of the roller brush.

[0180] In addition, in some embodiments, the curved surface 153 of the base 151 can also fit the roller brush as a whole. At this time, the jet cavity 150 provides a more prominent effect of lifting the bristles of the roller brush, and the curved surface 153 and the liquid separation portion 152 can both provide the function of pressing against the roller brush to disperse the liquid on the roller brush.

[0181] In addition, it can be understood that in some embodiments, the main body 13, the liquid separator 14 and the cover 15 can also be an integral structure. The cover 15, the liquid separator 14 and the main body 13 of the integral structure simplify the assembly process of the main body 13 and the liquid separator 14 compared with the cover 15, the liquid separator 14 and the main body 13 of the separate structure, which is conducive to improving the production efficiency of the overall liquid separator housing 1.

[0182] Optionally, in some embodiments, the total flow area S of the plurality of liquid spray holes 12 satisfies: 0.35 mm 2 ≤S≤1.84mm 2 . That is, S can be 0.35mm 2 Up to 1.84mm 2 The range value consisting of any one or any two of .

[0183] In some embodiments, the distance D between adjacent liquid spray holes 12 satisfies: 6.5 mm≤D≤14 mm, that is, D can be a range of any one of 6.5 mm to 14 mm or any two of them.

[0184] In some embodiments, the number a of the liquid spray holes 12 satisfies: 20≤a≤30. That is, a can be a range value consisting of any one of 20 to 30 or any two of them.

[0185] The total flow area of ​​the plurality of liquid spray holes 12 is further set to 0.35 mm 2 Up to 1.84mm 2The distance between adjacent spray holes 12 is set between 6.5 mm and 14 mm, and the number of spray holes 12 is set between 20 and 30, which is beneficial to further optimize the atomization effect of the spray liquid from multiple spray holes 12 and the uniform wetting effect of the spray roller brush, thereby improving the cleaning effect and cleaning efficiency of the roller brush.

[0186] In some embodiments, in the liquid spraying state, the initial velocity V0 of the liquid spraying flow from the liquid spraying hole 12 satisfies: 1 m / s≤V0≤5 m / s, that is, V0 can be any one of 1 m / s to 5 m / s or any two of the range values.

[0187] In the liquid spraying state, the speed of the liquid flow sprayed from the liquid spray hole 12 can reach 1m / s to 5m / s, which is beneficial to increase the spray distance of the liquid flow sprayed from the liquid spray port and the penetration ability of the wet roller brush, thereby improving the efficiency of the wet roller brush, so as to improve the problem of water stains caused by uneven wetting of the roller brush when cleaning the surface to be cleaned, and improve the cleaning efficiency of the roller brush.

[0188] In some embodiments, reference Figure 2 , the dimension L of the liquid separator 14 in the length direction X satisfies: 200mm≤L≤280mm. That is, L can be any one of 200mm to 280mm or a range of any two. By setting the length dimension of the liquid separator 14 between 200mm and 280mm, it is convenient to adapt to the length dimension of the roller brush, so that the liquid spraying holes 12 arranged on the liquid separator 14 can evenly spray liquid to the roller brush, thereby improving the uniformity of the roller brush wetting.

[0189] Correspondingly, the embodiment of the present application also discloses a floor brush. The floor brush includes a liquid separation component, a roller brush and a liquid pump. The liquid pump is used to pump liquid toward the liquid separation component, and the liquid separation component is used to spray the liquid source pumped by the liquid pump toward the roller brush through the liquid spray hole 12 and the jet chamber 150. It can be understood that during the process of the floor brush, the liquid separation component can evenly spray the liquid source toward the roller brush, improve the uniformity of the wetting of the roller brush, and thus improve the cleaning effect and cleaning efficiency of the floor brush.

[0190] Specifically, in some embodiments, in the liquid spraying state, the liquid pump flow rate Q of the liquid pump satisfies: 0<Q≤160g / min. The liquid pump may be an electromagnetic pump, a diaphragm pump, a peristaltic pump, or the like.

[0191] The floor brush can flexibly use a liquid pump that can work normally within the pump liquid flow range of 0 to 160g / min, so as to transport the liquid source toward the liquid separation component to stably spray the liquid source toward the roller brush, thereby achieving uniform wetting of the roller brush and improving the cleaning effect and cleaning efficiency of the roller brush.

[0192] Based on the pump liquid flow rate Q of the liquid pump, it is necessary to explain the calculation method of the initial velocity V0 of the liquid flow sprayed from the spray hole 12 in this embodiment, that is, the initial velocity V0 of the liquid flow sprayed from the spray hole 12 is actually equal to the pump liquid flow rate Q of the liquid pump divided by the total flow area S of multiple spray holes 12, that is, V0 = Q / S.

[0193] In addition, it should be noted that in this embodiment, the pipeline pressure p of the liquid pump inputting the liquid source into the liquid separation shell 1 is p=ρ×V0 2 / 2. Here, ρ is the density of the liquid used.

[0194] Based on the design scheme of the embodiment of the present application, the pressure that the liquid separation shell 1 needs to withstand in actual use can be reduced. At the same time, while meeting the atomization liquid source and improving the ability of the spray wet roller brush, the parameter requirements for the liquid pump are reduced, and the design difficulty of the liquid separation shell 1 is reduced.

[0195] Optionally, in some embodiments, in the liquid spraying state, the pump liquid flow rate Q of the liquid pump satisfies: 20g / min≤Q≤150g / min.

[0196] Further setting the pump liquid flow rate of the liquid pump at 20g / min to 150g / min is beneficial to ensure that the amount of liquid source delivered to the liquid separation component per unit time is sufficient, so as to stably spray the liquid source toward the roller brush, achieve uniform wetting of the roller brush, and improve the cleaning effect and cleaning efficiency of the roller brush.

[0197] Next, based on the embodiment of the present application, a further value range of the flow area S1 of the liquid spray hole 12 is set to 0.017 mm 2 Up to 0.071mm 2 The diameter d of the corresponding liquid injection hole 12 satisfies: 0.15mm≤d≤0.3mm.

[0198] Consider that the dimension L of the liquid separation member 14 in the length direction X satisfies: 200 mm ≤ L ≤ 280 mm, so as to match the length dimension of a conventional roller brush.

[0199] Based on the length L of the liquid separation member 14, the number of distribution of the liquid spray holes 12 is preset so that the distribution density of the liquid spray holes 12 along the length direction of the liquid separation member 14 is moderate. Considering that when the number of liquid spray holes 12 is set to be large, each liquid spray hole 12 is evenly distributed along the length direction X in a relatively extreme state, 35 liquid spray holes 12 are taken for testing; considering that when the actual hole diameter d of the conventional liquid spray hole 12 is less than or equal to 0.1mm, it is difficult to work normally or is very easy to be blocked in actual use, considering that the value of d in the extreme state is at least 0.11mm, combined with S1=πd 2 / 4, it can be concluded that when the number of the spray holes 12 is the largest and the diameter of the spray holes is the smallest in the limit state, S1 is approximately 0.01mm 2, corresponding to S is approximately 0.35mm 2 .

[0200] Based on the length dimension L of the liquid separation member 14, the number of distribution of the liquid spray holes 12 is preset so that the distribution density of the liquid spray holes 12 along the length direction of the liquid separation member 14 is moderate. Considering that when the number of liquid spray holes 12 is set to be small, in a relatively extreme state, each liquid spray hole 12 is evenly distributed along the length direction X, and 15 liquid spray holes 12 are taken for testing; combined with the actual hole diameter d of the conventional liquid spray hole 12 being greater than 0.45mm, it is difficult to form a good spray and atomization effect in actual use, and the liquid flow rate per unit time of a single hole is too large. Considering that the value of d is 0.45mm in the extreme state, combined with S1=πd 2 / 4, it can be concluded that when the number of the spray holes 12 is the least and the diameter of the spray holes is the largest in the limit state, S1 is approximately 0.16mm 2 , corresponding to S is approximately 2.51mm 2 .

[0201] According to the above-mentioned limit state, the value in this embodiment can be further optimized to adapt to the pressure bearing capacity of the conventional liquid separation component, and the infusion pressure is preferably controlled within 1 bar.

[0202] In this embodiment, the number of the liquid spray holes 12 is 20 as an example, and the number of the liquid spray holes 12 can be flexibly adjusted according to the length change of the liquid separation member 14. In this embodiment of the application, the pump liquid flow rate Q = 150g / min, the density of the liquid ρ = 1000kg / m 3 For example.

[0203] In test 1, the diameter of the spray hole 12 was d = 0.2 mm, S1 = 0.031 mm 2 For example, the number of the liquid spray holes 12 is a=20, that is, S=0.62 mm 2 , corresponding to the initial velocity of the test jet flow V0 = 3.98m / s, the pipeline pressure of the input liquid source in the liquid separation shell 1 p = 0.776bar, refer to Figure 6 That is, the spray distance and height variation trend of the liquid sprayed from the spray hole 12.

[0204] It can be determined that in reference test 1, when 0.15mm≤d≤0.3mm is satisfied and the pipeline pressure p of the liquid source input in the liquid separation shell 1 is lower than 1 bar, the initial velocity V0 of the sprayed liquid flow maintains a better output value and spray distance. Figure 6As shown in , after the spray liquid flow is sprayed out from the origin, the unit spraying distance is 0.5m per grid. In the first half of the unit spraying distance of the first grid, that is, within 0.25m, the liquid flow sprayed by the spray hole 12 basically maintains horizontal motion. Combined with the atomization effect of the spray hole 12 itself, the sprayed and atomized liquid flow of the spray hole 12 can roughly wet the roller brush while maintaining horizontal motion. In actual products, the distance between the spray hole 12 and the roller brush is actually much smaller than 0.25m. Therefore, in actual use, the spray hole 12 can spray and wet the corresponding roller brush area more accurately at this initial velocity, thereby achieving fully and evenly wetting the roller brush, improving the problem of water stains when cleaning the surface to be cleaned due to uneven wetting of the roller brush, and improving the cleaning efficiency of the roller brush.

[0205] Test 2: The diameter of the spray hole 12 is d = 0.1 mm, S1 = 0.008 mm 2 For example, the number of the liquid spray holes 12 is a=20, that is, S=0.16 mm 2 , corresponding to the initial velocity of the test jet flow V0 = 15.92m / s, the pipeline pressure of the input liquid source in the liquid separation shell 1 p = 12.412bar, refer to Figure 7 That is, the spray distance and height variation trend of the liquid sprayed from the spray hole 12.

[0206] In reference test 2, when d < 0.15 mm, the output value of the initial velocity V0 of the corresponding injection liquid flow is relatively large, but at this time, the pipeline pressure p of the input liquid source in the liquid separation shell 1 exceeds 12 bar, and the liquid separation shell 1 is subjected to a relatively large pressure. Figure 7 As shown in the figure, after the jet liquid flow is ejected from the origin, the unit jetting distance is 0.5m per grid. The liquid flow ejected from the jet hole 12 basically maintains horizontal motion within approximately two unit jetting distances due to the initial velocity V0 reaching 15.92m / s. In actual product applications, the required initial velocity requirement of the jet liquid flow from the jet hole 12 is much lower than 15.92m / s. At the same time, the pressure in the liquid separator shell needs to be as high as 12.412bar. The structural strength of conventional products is difficult to meet the pressure requirements, that is, it is difficult to be applied to conventional products.

[0207] Test 3: The diameter of the spray hole 12 is d = 0.4 mm, S1 = 0.126 mm 2 For example, the number of the liquid spray holes 12 is a=20, that is, S=2.52 mm 2 , corresponding to the initial velocity of the test jet flow V0 = 0.99m / s, the pipeline pressure of the input liquid source in the liquid separation shell 1 p = 0.048bar, refer to Figure 8 That is, the spray distance and height variation trend of the liquid sprayed from the spray hole 12.

[0208] In reference test 3, when d>0.3mm, the output value of the initial velocity V0 of the corresponding injection liquid flow is small, and the injection distance of the injection hole 12 is not good at this time. Figure 8 As shown in the figure, after the liquid flow is ejected from the origin, the unit ejection distance is 0.5m per grid. The liquid flow ejected from the liquid spray hole 12 has an initial velocity V0 of only 0.99m / s. At this time, the pipeline pressure p of the liquid source input in the liquid separation shell 1 is only 0.048bar, resulting in that in actual use, the liquid flow ejected from the liquid spray hole 12 has a downward trend after being output from the liquid spray hole 12. In actual product applications, it manifests as a slow liquid output speed, a short ejection distance, and the sprayed liquid tends to flow to a low place. The liquid output from the liquid spray hole 12 is difficult to accurately fall on the corresponding position of the roller brush, and the roller brush cannot be evenly wetted, affecting the user experience.

[0209] Therefore, comprehensive consideration meets: 0.35mm 2 ≤S≤2.51mm 2 ,0.15mm≤d≤0.3mm,0.017mm 2 ≤S1≤0.071mm 2 When the roller brush is cleaned, the spray hole 12 can spray and moisten the corresponding roller brush area more accurately, thereby fully and evenly moistening the roller brush, improving the problem of water stains caused by uneven moistening of the roller brush when cleaning the surface to be cleaned, and improving the cleaning efficiency of the roller brush.

[0210] The embodiment of the present application also discloses a cleaning device. The cleaning device includes the above-mentioned liquid separation component or floor brush. The cleaning device can be a floor scrubber or other products with a liquid separation component or floor brush and a cleaning function.

[0211] The cleaning equipment can flexibly use the liquid-separating component or the floor brush alone to meet the needs of different usage scenarios. When the liquid-separating component is used alone, the cleaning equipment has the effect of atomizing the liquid source and spraying the liquid source evenly. When the floor brush is used, during the operation of the cleaning equipment, the liquid-separating component of the floor brush evenly sprays the atomized liquid source toward the rotating roller brush, thereby improving the wetting uniformity of the roller brush, thereby improving the cleaning effect and cleaning efficiency of the cleaning equipment.

[0212] The embodiment of the present application also discloses a cleaning system, including a cleaning device and a base station or a charging base compatible with the cleaning device.

[0213] It should be noted that the cleaning equipment also includes a clean liquid tank and a dirty liquid tank, wherein the clean liquid tank is used to store the cleaning liquid source to be used, and the dirty liquid tank is used to store the dirty liquid generated after cleaning.

[0214] It should be noted that the difference between the base station and the charging stand described in this embodiment is that when using a base station compatible with the cleaning equipment, the base station can provide the cleaning equipment with functions such as supplying liquid to the clean liquid tank, draining liquid from the dirty liquid tank, self-cleaning and drying of the roller brush, and charging of the cleaning equipment, while when using the charging stand, the charging stand can provide the cleaning equipment with functions such as charging, self-cleaning and drying.
