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 a floor scrubber needs to continuously spray cleaning liquid toward a roller brush through a liquid spraying structure, so as to wet the roller brush before the roller brush cleans the surface to be cleaned, thereby facilitating the roller brush to perform cleaning operations.

[0003] However, cleaning equipment such as floor scrubbers generally have the problem of uneven liquid spraying on the roller brush, which easily causes the middle part of the roller brush to be wetted earlier and more fully than the two ends in the length direction, which in turn causes water stains on the cleaning surface when the roller brush is used for cleaning, 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 spray hole of the floor brush mechanism does not use steam, it cannot achieve good liquid atomization and uniform liquid spraying, and it also cannot solve the problem of water stains. 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 receiving cavity, the liquid separation shell is provided with a liquid inlet connected to the receiving cavity, the liquid separation shell is provided with a plurality of spray structures, the plurality of spray structures are connected to the receiving cavity, and the spray structure is provided with a nozzle for spraying water mist toward the roller brush, and the total flow area of ​​the plurality of nozzles is smaller than the flow area of ​​the liquid inlet;

[0007] The total flow area S of the plurality of nozzles satisfies: 0.35 mm 2 ≤S≤2.51mm 2 .

[0008] 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 nozzles is smaller than the flow area of ​​the liquid inlet, a liquid spraying pressure is formed at the nozzles. The liquid sprayed by the atomizing structure is coordinated with the overall spray structure, which is beneficial to increase the liquid spraying speed of the nozzles, expand the spraying range of the nozzles toward the roller brush, and enhance the wetting and penetration effect on the roller brush. The nozzles actually need to be set on the surface of the liquid separation component opposite to the roller brush. The length size of the liquid separation component needs to be adapted to the length size of the roller brush. When setting the size of each nozzle, if the opening of the nozzle is too large, it is easy to cause the nozzle to overflow. The area and the total flow area of ​​all nozzles are too large, which causes the spray pressure and the flow rate of the sprayed liquid at the nozzle to decrease, and the actual spraying of the nozzle, the atomization effect and uniformity of the wet roller brush will decrease. If the nozzle opening is too small, it is easy to cause the nozzle flow area and the total flow area of ​​all nozzles to be too small. At this time, the spray pressure and the flow rate of the sprayed liquid at the nozzle will be higher, and the nozzle is more likely to be blocked, and the liquid separation component needs to withstand excessive water delivery pressure; the single flow area and total flow area of ​​the nozzle with better spraying and wet roller brush uniformity can be obtained, and the total flow area of ​​multiple nozzles is further set at 0.35mm 2 Up to 2.51mm 2 It is beneficial to further optimize the atomization effect of the spray liquid from multiple nozzles 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.

[0009] 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 nozzle is arranged on the liquid separation member.

[0010] By adopting the above technical solution, the main body and the liquid separation part jointly form a containing chamber for accommodating the liquid source. When the liquid separation shell is in working state, the liquid source is introduced into the containing chamber from the liquid inlet, and the liquid is atomized through the spray structure and sprayed out from the nozzle, thereby realizing the input and output of the liquid source into and out of the liquid separation shell.

[0012] 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.

[0013] By adopting the above technical solution, the split-assembly main body and the liquid-separating parts can be independently disassembled and assembled, which is beneficial to the subsequent maintenance, replacement and other operations of the liquid-separating shell. In addition, the split-assembly main body and the liquid-separating parts can be independently processed, which is beneficial to reduce the processing difficulty of the overall liquid-separating shell and improve the yield rate of liquid-separating shell manufacturing.

[0014] In some embodiments, the main body and the liquid separation member are an integral structure.

[0015] By adopting the above technical solution, the main body and the liquid separation part of the integrated structure simplify the assembly steps of the main body and the liquid separation part in the manufacturing process compared with the main body and the liquid separation part of the split structure, which is beneficial to improve the production efficiency of the overall liquid separation shell.

[0016] 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 nozzles are connected to the jet cavity to spray liquid toward the roller brush.

[0017] By adopting the above technical solution, during the operation of the liquid separation shell, each nozzle 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.

[0018] In some embodiments, the jet chamber is provided with a;

[0019] Alternatively, the jet chamber is provided with a plurality of jet chambers, at least some of the jet chambers are spaced apart from each other, and each of the jet chambers is connected to at least one of the nozzles.

[0020] By adopting the above technical solution, only one jet chamber can be provided, that is, multiple nozzles all spray liquid toward the roller brush from one jet chamber. In addition, the jet chambers can also be provided in multiple spaces between each other, and each jet chamber can correspond to at least one nozzle, which is beneficial to further optimize the guiding effect of the jet chamber for each nozzle and improve the uniformity of wetting the roller brush.

[0021] In some embodiments, the cover body includes a base and a liquid separation portion disposed on the base, and the jet chamber is disposed on the base;

[0022] The liquid separation shell has a spray state for spraying water mist toward the roller brush. In the spray state, the jet chamber sprays liquid toward the roller brush and wets the roller brush. 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.

[0023] 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.

[0024] In some embodiments, the cover and the main body are separate assembly structures;

[0025] 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.

[0026] By adopting the above technical solution, the cover body, the main body and the liquid separator are all independent components. The cover body can be independently disassembled and assembled relative to the main body and the liquid separator, which is conducive to the subsequent maintenance and replacement of the cover body. In addition, the separately assembled cover body, liquid separator and main body can be independently processed, which is conducive to reducing the processing difficulty of the overall liquid separator shell and improving the yield rate of the liquid separator shell manufacturing. In addition, when the cover body and the liquid separator are designed as an integrated structure, it is conducive to further simplifying the assembly structure of the overall liquid separator shell, simplifying the assembly steps of the cover body and the liquid separator in the process production, and improving the assembly efficiency of the liquid separator shell.

[0027] In some embodiments, the liquid separation shell further comprises a cover body, the cover body is arranged on a side of the liquid separation member away from the main body, the cover body is penetrated by a jet cavity, and the plurality of nozzles are connected to the jet cavity to spray liquid toward the roller brush;

[0028] The cover body and the liquid separation component are an integrated structure.

[0029] By adopting the above technical solution, the integrated structure of the cover body, the liquid separator and the main body simplifies the assembly steps of the cover body, the liquid separator and the main body in the process production compared with the separate structure of the cover body, the liquid separator and the main body, which is beneficial to improve the production efficiency of the overall liquid separator shell.

[0030] In some embodiments, the liquid separation shell has a length direction, and at least part of the nozzles are distributed along the length direction of the liquid separation shell.

[0031] By adopting the above technical solution, the nozzles 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 nozzles to evenly spray liquid to the roller brush and improve the uniformity of the roller brush wetting.

[0032] In some embodiments, the total flow area S of the plurality of nozzles satisfies: 0.35 mm 2 ≤S≤1.84mm 2 .

[0033] By adopting the above technical solution, the total flow area of ​​multiple nozzles is further set at 0.35mm 2 Up to 1.84mm 2 It is beneficial to further optimize the atomization effect of the liquid spray from multiple nozzles and the uniform wetting effect of the spray roller brush, thereby improving the cleaning effect and cleaning efficiency of the roller brush.

[0034] In some embodiments, the spray structure includes a mixing chamber provided in the liquid separation shell, the mixing chamber is connected to the accommodating chamber and the nozzle, and the mixing chamber is used to transport fluid toward the nozzle so that the nozzle sprays water mist toward the roller brush.

[0035] By adopting the above technical solution, 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, the liquid is introduced into the mixing chamber and sprayed out from the nozzle, so that the liquid forms an atomization effect at the nozzle, realizing the input of the liquid source and the atomization output.

[0036] In some embodiments, the liquid separation shell is provided with an air inlet connected to the mixing chamber, and the spray structure has a spray state of spraying water mist toward the roller brush;

[0037] In the spray state, gas is transported from the air inlet toward the mixing chamber, and liquid is transported from the accommodating chamber toward the mixing chamber. The gas and liquid are mixed in the mixing chamber and sprayed with water mist from the nozzle.

[0038] By adopting the above technical scheme, in the spray state, the liquid source is transported from the liquid inlet to the mixing chamber via the containing chamber, and at the same time, the pressurized gas is transported from the air inlet toward the mixing chamber. The gas and liquid are mixed in the mixing chamber and sprayed out from the nozzle, thereby further enhancing the liquid spray pressure at the nozzle, which is beneficial to improving the atomization effect of the liquid spray at the nozzle, thereby improving the uniform wetting effect of the spray roller brush, reducing 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.

[0039] In some embodiments, the mixing chamber is used to form a vortex that transports liquid toward the nozzle, so that the nozzle sprays water mist toward the roller brush.

[0040] By adopting the above technical scheme, when the liquid separation component is used to spray liquid toward the roller brush, the liquid source is input into the containing chamber from the liquid inlet and transported into the mixing chamber. The liquid forms a vortex in the mixing chamber and is output toward the nozzle, which is beneficial to atomize the sprayed liquid at the nozzle, and is beneficial to improve the atomization effect of the sprayed liquid at the nozzle, thereby improving the uniform wetting effect of the spray roller brush, reducing 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.

[0041] In some embodiments, the spray structure further comprises a plurality of flow channels disposed on the liquid separation shell, at least part of the flow channels surround the mixing chamber, and the flow channels are connected to the mixing chamber and the containing chamber respectively;

[0042] The spray structure has a spray state of spraying water mist toward the roller brush. In the spray state, the liquid in the accommodating chamber can be surrounded by the plurality of flow channels and input into the mixing chamber to form a vortex in the mixing chamber.

[0043] By adopting the above technical scheme, in the spray state, after the liquid source is input into the containing chamber from the liquid inlet, it is surrounded by a plurality of flow channels and input into the mixing chamber respectively. That is, through the surrounding arrangement of the flow channels, the liquid in the containing chamber is divided and input into the mixing chamber and forms a vortex flow, so that after converging into the mixing chamber, they intersect with each other and form a vortex outputted toward the nozzle, thereby improving the effect of vortex formation in the mixing chamber and improving the atomization effect of the liquid sprayed out of the nozzle.

[0044] In some embodiments, the flow channel has an output end connected to the mixing chamber, and the flow cross-section of the output end in the infusion direction of the flow channel is at least partially offset from the nozzle.

[0045] By adopting the above technical solution, when the output end inputs liquid into the mixing chamber, at least part of the flow cross-section of the output end is offset from the nozzle, thereby avoiding at least part of the liquid output from the output end from being directly input into the nozzle, reducing the loss of liquid used to form a vortex, and improving the effect of fully mixing the liquids input from each flow channel in the mixing chamber to form a vortex.

[0046] In some embodiments, a plurality of water guide parts are provided in the mixing chamber, and each water guide part is provided corresponding to each of the output ends;

[0047] In the spray state, in the direction surrounding the mixing chamber, the liquid output from one of the adjacent output ends is guided by its corresponding water guide portion toward the other water guide portion, so that the liquid output from the adjacent output ends converges in the mixing chamber and forms a vortex.

[0048] By adopting the above technical solution, in the spray state, when the liquid is input into the mixing chamber from each flow channel, it is guided by the water guide part to another water guide part, so that the liquids in adjacent flow channels form an intersection, that is, the water guide parts cooperate with each other to guide the liquid input into the mixing chamber from each flow channel to form a flow around the nozzle, thereby forming a vortex outside the nozzle, which is beneficial to improving the effect of vortex formation in the mixing chamber and improving the atomization effect of the liquid sprayed from the nozzle.

[0049] In some embodiments, in the direction surrounding the mixing chamber, the infusion directions of adjacent output ends have an intersection angle α, satisfying 0°<α<90°.

[0050] By adopting the above technical solution, the intersection angle of the liquids output from adjacent output ends is set between 0° and 90°, which is conducive to the liquids output from adjacent output ends to form a superimposed intersection flow effect during the intersection process. Compared with the intersection angle of the liquids output from adjacent output ends being greater than 90°, the problem of mutual weakening of flow potential when the liquids output from adjacent output ends intersect is reduced, ensuring that the flow channels cooperate with each other to fully mix in the mixing chamber and form a vortex effect.

[0051] In some embodiments, the flow channel has an input end connected to the accommodating chamber and an output end connected to the mixing chamber, and the flow area of ​​the output end is smaller than the flow area of ​​the input end.

[0052] By adopting the above technical solution, in the process of liquid passing through the flow channel, since the flow area at the input end is smaller than the flow area at the output end, an output pressure is formed at the output end, which is beneficial to speed up the flow rate of the liquid output from the output end toward the mixing chamber, thereby helping to speed up the mixing efficiency of the liquid input into each flow channel in the mixing chamber and the effect of vortex formation, and improving the atomization effect of the liquid sprayed out from the nozzle.

[0053] In some embodiments, the flow area of ​​the flow channel in its own infusion direction decreases from the input end to the output end.

[0054] By adopting the above technical solution, in the process of liquid passing through the flow channel, the flow area of ​​the flow channel is continuously reduced to gradually increase the pressure on the liquid, which is beneficial to speed up the flow rate of the liquid output from the output end toward the mixing chamber, thereby helping to speed up the mixing efficiency of the liquid input into each flow channel in the mixing chamber and the effect of vortex formation, and improving the atomization effect of the liquid sprayed out from the nozzle.

[0055] In some embodiments, the nozzle has a length dimension d along its own infusion direction, satisfying: 0.1 mm≤d≤0.15 mm.

[0056] By adopting the above technical solution, the length dimension of the nozzle along its own infusion direction is set between 0.1mm and 0.15mm, so as to avoid the nozzle being too small in the infusion direction, causing the wall thickness of the liquid separation shell to be too low, resulting in too low structural strength at the nozzle, and at the same time avoid the nozzle being too large in the infusion direction, so that the vortex formed in the mixing chamber needs to travel a longer distance before being ejected from the nozzle, reducing the obstruction of the vortex flow potential at the nozzle, which is conducive to ensuring the atomization effect of the liquid output at the nozzle.

[0057] In some embodiments, the spray structure also includes a guide portion, which is arranged in the accommodating chamber and connected to the liquid separation shell, the liquid separation shell is provided with a vortex groove and a flow channel groove connected to the vortex groove, and the vortex groove is connected to the nozzle, and the guide portion cover is arranged on the vortex groove and the flow channel groove to enclose the mixing chamber and the flow channel.

[0058] By adopting the above technical scheme, in the process of producing the liquid separation shell, interconnected vortex grooves and flow channel grooves are pre-opened on the liquid separation shell, and the guide part is covered on the vortex grooves and the flow channel, so that the guide part and the liquid separation shell are enclosed to form a mixing chamber and a flow channel, which is beneficial to simplify the overall processing steps of the liquid separation shell in terms of technology, ensures that the processing and molding difficulty of the mixing chamber and the flow channel is relatively low, and facilitates the rapid batch production of the liquid separation shell.

[0059] 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 water mist toward the roller brush.

[0060] By adopting the above technical solution, during the use of the floor brush, the liquid separation component can atomize the liquid source and evenly spray water mist toward the roller brush, thereby improving the uniformity of the wetting of the roller brush, 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.

[0061] Correspondingly, a cleaning device described in an embodiment of the present application includes the above-mentioned liquid separation component or floor brush.

[0062] By adopting the above technical scheme, the cleaning equipment can flexibly use the liquid-separating component or the floor brush alone, so as 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 atomizes the liquid source and sprays water mist evenly toward the rotating roller brush, thereby improving the wetting uniformity of the roller brush, 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.

[0063] 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.

[0064] 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.

[0065] 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 nozzles is smaller than the flow area of ​​the liquid inlet, a spraying pressure is formed at the nozzles. The overall spray structure atomizes the sprayed liquid, which is beneficial to increase the spraying speed of the nozzles, expand the spraying range of the nozzles toward the roller brush, and enhance the wetting and penetration effect on the roller brush. The nozzle 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 nozzle, if the opening of the nozzle is too large, it is easy to cause the nozzle flow area and the total flow area of ​​all nozzles to be too large. At this time, the spray pressure at the nozzle and the flow rate of the sprayed liquid will decrease, and the actual spraying of the nozzle, the atomization effect and uniformity of the wetting roller brush will decrease. If the opening of the nozzle is too small, it is easy to cause the nozzle flow area and the total flow area of ​​all nozzles to be too small. At this time, the spray pressure at the nozzle and the flow rate of the sprayed liquid will be higher, and the nozzle is more likely to be blocked, and the liquid separation component needs to withstand excessive water supply pressure; at the same time, the number and spacing of the nozzles need to be reasonably arranged to improve the uniformity of each nozzle spraying on the roller brush, and further set the total flow area of ​​multiple nozzles to 0.35mm 2 Up to 2.51mm 2 It is beneficial to further optimize the atomization effect of the spray liquid from multiple nozzles 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.

[0079] 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 as to facilitate the roller brush to clean the surface to be cleaned. The liquid spraying structure usually needs to adapt to the nozzles set on the roller brush for spraying liquid, but the number of nozzles is limited, and it is difficult to spray liquid evenly on the roller brush, resulting in the roller brush often appearing in the middle of the length direction The part is wetted earlier than the two ends, and the overall wetting uniformity is poor, which affects the cleaning effect and cleaning efficiency of the roller brush;

[0080] 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.

The liquid inlet 11 and the nozzles 120 are distributed on both sides of the liquid separation housing 1 in the width direction Y, so as to provide sufficient space for the liquid inlet 11 to be connected to an external infusion pipeline, thereby avoiding affecting the arrangement and liquid spraying of the nozzles 120.

[0086] It should be noted that the roller brush 2 can be arranged on a 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.

[0087] The total flow area of ​​the plurality of nozzles 120 is smaller than the flow area of ​​the liquid inlet 11, and the total flow area S of the plurality of nozzles 120 satisfies: 0.35 mm 2 ≤S≤2.51mm 2That 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] It should be noted that, in this embodiment, the flow cross-sectional shapes of the liquid inlet 11 and the nozzle 120 are both circular in design, that is, the flow area of ​​a single nozzle 120 can be directly calculated by measuring the radial dimension of the nozzle 120. Specifically, the flow area of ​​a single nozzle 120 = π × (radius of the nozzle 120) 2 / 2, after calculating the flow area of ​​a single nozzle 120, the total flow area of ​​multiple nozzles 120 can be obtained by multiplying the designed number of nozzles 120.

[0089] 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.

[0090] In other embodiments, the flow cross-section of the liquid inlet 11 and the nozzle 120 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 by the corresponding polygon area calculation formula. In addition, in other embodiments, the flow cross-section of the liquid inlet 11 and the nozzle 120 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 nozzle 120 through a computer, which will not be described in detail here.

[0091] When the liquid separation component is used to spray liquid toward the roller brush 2, the liquid source is transported from the liquid inlet 11 to the accommodating chamber 10. Since the total flow area of ​​the multiple nozzles 120 is smaller than the flow area of ​​the liquid inlet 11, a liquid spraying pressure is formed at the nozzles 120. The liquid sprayed by the atomization of the overall spray structure 12 is helpful to increase the liquid spraying speed of the nozzles 120, expand the spraying range of the nozzles 120 toward the roller brush 2, and enhance the wetting and penetration effect on the roller brush 2. The nozzles 120 actually need to be arranged on the surface opposite to the roller brush 2 of the liquid separation component. According to the need to adapt the length of the liquid separation component to the length of the roller brush 2, when setting the size of each nozzle 120, if the opening of the nozzle 120 is too large, it is easy to cause the flow area of ​​the nozzle 120 and the total flow area of ​​all nozzles 120 to be too large, at this time, the spray pressure at the nozzle 120 and the flow rate of the sprayed liquid will decrease, and the actual spraying of the nozzle 120, the atomization effect and uniformity of the wet roller brush will decrease. If the opening of the nozzle 120 is too small, it is easy to cause the flow area of ​​the nozzle 120 and the total flow area of ​​all nozzles 120 to be too large. 0 is too small, at this time, the spray pressure and the flow rate of the sprayed liquid at the nozzle 120 are both high, and the nozzle 120 is more likely to be blocked, and the liquid separation component needs to withstand too large a water delivery pressure; at the same time, the number and spacing of the nozzles 120 need to be reasonably arranged to improve the uniformity of the liquid spraying of each nozzle 120 on the roller brush 2. If the spacing between adjacent nozzles 120 is too large, it is easy to cause insufficient coverage of the spray, and if the spacing between adjacent nozzles 120 is too small, the nozzle 120 is arranged too densely, resulting in adjacent nozzles 12 0 The spray coverage range is excessively crossed, which will cause uneven spraying and wetting of the roller brush 2; combined with the pump water flow rate used by the conventional liquid separation component and the pressure range that the water delivery pipeline of the liquid separation component toward the nozzle 120 can withstand, the reasonable aperture and number of the nozzles 120 are set, and the single flow area, total flow area and spacing between adjacent nozzles 120 with better uniformity of spraying and wetting the roller brush 2 can be obtained. The total flow area of ​​multiple nozzles 120 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 the multiple nozzles 120 and the uniform wetting effect of the spray roller brush 2, improve the problem of water stains generated when cleaning the surface to be cleaned due to uneven wetting of the roller brush 2, and improve the cleaning efficiency of the roller brush 2.

[0092] Specifically, in some embodiments, referring to Figures 1 to 9 The liquid separation housing 1 includes a main body 13 , a liquid separation member 14 and a cover body 15 .

[0093] 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 spray structure 12 is arranged between the liquid separator 14 and the cover 15. 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.

[0094] In order to improve the positioning accuracy and installation stability of the liquid separation member 14, as Figure 8 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.

[0095] In some embodiments, reference Figure 2 and Figure 3 , at least part of the spray structures 12 are distributed along the length direction X. In this embodiment, it is taken as an example that all the spray structures 12 are evenly distributed along the length direction X, that is, all the nozzles 120 are distributed along the length direction X in the liquid separation member 14 .

[0096] 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 working state, the liquid source is introduced into the receiving chamber 10 through the liquid inlet 11 and atomized by the spray structure 12, so that the nozzle 120 sprays water mist, realizing the input and output of the liquid source into and out of the liquid separation shell 1.

[0097] After the liquid separator 14 is installed relative to the roller brush 2 , the corresponding roller brush 2 can also be installed in an adaptable manner with the liquid separator 14 along the length direction X, which is conducive to the nozzle 120 to evenly spray water mist to the roller brush 2 and improve the uniformity of wetting the roller brush 2 .

[0098] In some embodiments, reference Figure 4 , Figure 7 and Fig. 9 The spray structure 12 includes a mixing chamber 121 disposed in the liquid separation shell 1 and a plurality of flow channels 122 connected to the mixing chamber 121. The mixing chamber 121 is connected to the accommodating chamber 10 through the plurality of flow channels 122, and the mixing chamber 121 is used to form a vortex for conveying liquid toward the nozzle 120, so that the nozzle 120 sprays water mist toward the roller brush 2.

[0099] In some embodiments, reference Figure 4 , at least part of the flow channels 122 surround the mixing chamber 121. Specifically, in this embodiment, a plurality of flow channels 122 are uniformly arranged around the mixing chamber 121 in the circumferential direction as an example.

[0100] The spray structure 12 has a spray state of spraying water mist toward the roller brush 2. In this embodiment, the spray state can be a stable state in which the nozzle 120 sprays water mist toward the roller brush 2. In the spray state, the liquid in the accommodating chamber 10 can be surrounded by multiple flow channels 122 and input into the mixing chamber 121. Through the surrounding arrangement of each flow channel 122, the liquid in the accommodating chamber 10 is divided into the mixing chamber 121 and forms a vortex flow, so that after being collected in the mixing chamber 121, they intersect with each other and form a vortex output toward the nozzle 120, thereby improving the effect of vortex formation in the mixing chamber 121 and improving the atomization effect of the liquid sprayed at the nozzle 120, improving the uniform wetting effect of the spray roller brush 2, reducing the problem of water stains caused by uneven wetting of the roller brush 2 when cleaning the surface to be cleaned, and improving the cleaning efficiency of the roller brush 2.

[0101] In some embodiments, reference Figure 3 , Figure 4 , Figure 7 as well as Fig. 9 The spray structure 12 also includes a guide portion 124, which is disposed in the accommodating chamber 10 and connected to the main body 13. The liquid separation member 14 is provided with a vortex groove 140 and a flow channel groove 141 connected to the vortex groove 140 toward the guide portion 124, and the vortex groove 140 is connected to the nozzle 120. The guide portion 124 covers the vortex groove 140 and the flow channel groove 141 to enclose the mixing chamber 121 and the flow channel 122.

[0102] It is understandable that, referring to Fig. 9 As shown, in this embodiment, the guide portion 124 can be pre-formed integrally with the main body 13, that is, the guide portion 124 is actually designed as a convex column structure protruding from the main body 13 toward the liquid separation member 14. This is conducive to simplifying the processing technology of the guide portion 124 and reducing the difficulty of assembling the guide portion 124 and the liquid separation member 14.

[0103] During the production of the liquid-separating shell 1, the liquid-separating member 14 is provided with interconnected vortex grooves 140 and flow channel grooves 141 in advance, and the flow guide 124 is preset on the main body 13. When the main body 13 and the liquid-separating shell 1 are combined to form the accommodating chamber 10, the end of the flow guide 124 away from the main body 13 abuts against the liquid-separating member 14 and covers the vortex grooves 140 and the flow channel grooves 141, so as to be combined with the liquid-separating member 14 to form the mixing chamber 121 and the flow channel 122. This is beneficial to simplifying the overall processing steps of the liquid-separating shell 1 in terms of technology, ensuring that the processing and molding difficulty of the mixing chamber 121 and the flow channel 122 is low, and facilitating rapid batch production of the liquid-separating shell 1.

[0104] Specifically, in this embodiment, the liquid separating component 14 can be made of metal material. At this time, process means such as chemical reagent etching, laser etching, etc. can be used to etch the surface of the liquid separating component 14, so as to form the above-mentioned vortex groove 140 and flow channel groove 141. In addition, the liquid separating component 14 can also be made of materials such as ceramics, and process means such as laser etching can also be used at this time, which will not be repeated here.

[0105] In addition, in some embodiments, reference Figure 4 and Figure 5 The guide portion 124 can also be designed as an end cover structure that is only connected to the liquid separation member 14 and covers the vortex groove 140 and the flow channel groove 141. It can be understood that the structural design of the guide portion 124 only needs to ensure that the guide portion 124 can be mutually enclosed with the liquid separation member 14 to form the mixing chamber 121 and the flow channel 122, and does not affect the smooth input of the liquid into the mixing chamber 121 and the formation of the vortex, and will not be repeated here.

[0106] In some embodiments, reference Figure 4 The flow channel 122 has an input end 1221 connected to the accommodating chamber 10 and an output end 1220 connected to the mixing chamber 121 in its own infusion direction.

[0107] It can be understood that the above-mentioned input end 1221 is actually formed when the guide part 124 covers the flow channel groove 141, relying on the size design of the guide part 124, the vortex groove 140 and the flow channel groove 141, so that the guide part 124 does not completely cover the end of the flow channel groove 141 away from the vortex groove 140.

[0108] In this embodiment, at least part of the flow cross section of each output end 1220 in the liquid infusion direction of the flow channel 122 is misaligned with the nozzle 120. That is, when the output end 1220 inputs liquid into the mixing chamber 121, at least part of the flow cross section of the output end 1220 is misaligned with the nozzle 120, thereby preventing at least part of the liquid output from the output end 1220 from being directly input into the nozzle 120, reducing the loss of liquid kinetic energy used to form a vortex, and improving the effect of fully mixing the liquid input from each flow channel 122 in the mixing chamber 121 and forming a vortex.

[0109] Specifically, when the vortex groove 140 and the flow channel groove 141 are provided, the exemplary embodiment is as follows: Figure 4As shown, a shape similar to a spiral blade is formed on the liquid separation member 14. At this time, a water guide portion 123 is provided at each output end 1220 in the mixing chamber 121. In this embodiment, the water guide portion 123 is actually a part of the liquid separation member 14. The water guide portion 123 extends from the corresponding output end 1220 toward the water guide portion 123 of the adjacent output end 1220. In the spray state, in the direction surrounding the mixing chamber 121, the liquid output from one of the adjacent output ends 1220 is guided by its corresponding water guide portion 123 toward the corresponding water guide portion 123 of the other output end 1220, so that the liquid output from the adjacent output ends 1220 intersects in the mixing chamber 121 and forms a vortex.

[0110] It can be understood that when the liquid is input into the mixing chamber 121 from each flow channel 122, it is guided by the water guide portion 123 to another water guide portion 123, so that the liquids in adjacent flow channels 122 are intersected, that is, the water guide portions 123 cooperate with each other to guide the liquid input into the mixing chamber 121 from each flow channel 122 to form a flow around the nozzle 120, thereby forming a vortex outside the nozzle 120, which is beneficial to improving the effect of vortex formation in the mixing chamber 121 and improving the atomization effect of the liquid sprayed from the nozzle 120.

[0111] More specifically, in some embodiments, referring to Figure 4 As shown, Figure 4 In the schematic diagram of two adjacent flow channels 122, in the spray state, the infusion direction of one of the flow channels 122 toward the mixing chamber 121 is defined as the first flow direction Z 1 The infusion direction of the other flow channel 122 toward the mixing chamber 121 is defined as the second flow direction Z 2 , the first flow direction Z 1 and the second flow direction Z 2 The intersection position generates an angle α, that is, the infusion directions of adjacent output ends 1220 toward the mixing chamber 121 have an intersection angle α.

[0112] In the direction surrounding the mixing chamber 121, 0°<α<90° is satisfied, that is, the intersection angle α is set to an acute angle. α can be 1°, 2°, 3°, 4°, 5°, 6°, 7°, 8°, 9°, 10°, 11°, 12°, 13°, 14°, 15°, 16°, 17°, 18°, 19°, 20°, 21°, 22°, 23°, 24°, 25°, 26°, 27°, 28°, 29°, 30°, 31°, 32°, 33°, 34°, 35°, 36°, 37°, 38°, 39°, 40°, 41°, 42°, 43°, 44°, 45°, 46°, 47°, The range value consists of any one of 48°, 49°, 50°, 51°, 52°, 53°, 54°, 55°, 56°, 57°, 58°, 59°, 60°, 61°, 62°, 63°, 64°, 65°, 66°, 67°, 68°, 69°, 70°, 71°, 72°, 73°, 74°, 75°, 76°, 77°, 78°, 79°, 80°, 81°, 82°, 83°, 84°, 85°, 86°, 87°, 88°, and 89°, or any two of them.

[0113] At this time, the intersection angle of the liquids output from each adjacent output end 1220 is between 0 and 90°, which is beneficial for the liquids output from the adjacent output ends 1220 to form a superimposed intersection flow effect during the intersection process. Compared with the liquids output from the adjacent output ends 1220 having an intersection angle greater than 90°, the problem of mutual weakening of flow potential when the liquids output from the adjacent output ends 1220 intersect is reduced, thereby ensuring that the flow channels 122 cooperate with each other to fully mix in the mixing chamber 121 and form a vortex effect.

[0114] In addition, in some embodiments, the intersection angle α may also be greater than or equal to 90°.

[0115] In addition, in some embodiments, reference Figure 4 The flow area of ​​the output end 1220 is smaller than the flow area of ​​the input end 1221 , so that an output pressure is formed at the output end 1220 , which is beneficial to speed up the flow rate of the liquid output from the output end 1220 toward the mixing chamber 121 .

[0116] Specifically, in this embodiment, the flow area of ​​the flow channel 122 in the direction of its own liquid infusion decreases from the input end 1221 to the output end 1220. That is, in the process of the liquid passing through the flow channel 122, the flow area of ​​the flow channel 122 is continuously reduced to gradually increase the pressure on the liquid, which is conducive to accelerating the flow rate of the liquid output from the output end 1220 toward the mixing chamber 121, thereby facilitating the mixing efficiency of the liquid input from each flow channel 122 in the mixing chamber 121 and the effect of vortex formation, and improving the atomization effect of the liquid sprayed from the nozzle 120.

[0117] In addition, in some embodiments, reference Figure 8 The nozzle 120 has a length dimension d along its own infusion direction, which satisfies: 0.1 mm ≤ d ≤ 0.15 mm. The value of d can be any one of 0.1, 0.11, 0.12, 0.13, 0.14, 0.15 or a range of any two of them.

[0118] It is understandable that the length of the nozzle 120 along its own infusion direction is set between 0.1 mm and 0.15 mm to avoid the nozzle 120 being too small in the infusion direction, so that the residual wall thickness after the groove on the liquid separation member 14 and the nozzle 120 is too low, resulting in too low structural strength at the nozzle 120. At the same time, the nozzle 120 is prevented from being too large in the infusion direction, so that the vortex formed in the mixing chamber 121 needs to pass a longer distance before being ejected from the nozzle 120, reducing the obstruction of the nozzle 120 to the vortex flow potential, which is conducive to ensuring the atomization effect of the liquid output at the nozzle 120.

[0119] In addition, in some embodiments, the liquid separation shell 1 can also use gas pressurization to make the nozzle 120 spray water mist. Specifically, the liquid separation shell 1 can be provided with an air inlet connected to the mixing chamber 121. It is understandable that the air inlet can be provided on the main body 13 to directly ventilate and pressurize the accommodating chamber 10. It is also possible to set a gas flow path for each mixing chamber 121 on the liquid separation member 14, and ventilate and pressurize each mixing chamber 121 through a unified air inlet provided on the liquid separation member 14.

[0120] In the spray state, the liquid source is transported from the liquid inlet 11 to the mixing chamber 121 via the accommodating chamber 10, and at the same time, pressurized gas is transported from the air inlet toward the mixing chamber 121. The gas and liquid are mixed in the mixing chamber 121 and sprayed out from the nozzle 120, which further enhances the liquid spraying pressure at the nozzle 120, and is beneficial to improving the atomization effect of the liquid sprayed from the nozzle 120, thereby improving the uniform wetting effect of the spray roller brush 2, reducing the problem of water stains caused by uneven wetting of the roller brush 2 when cleaning the surface to be cleaned, and improving the cleaning efficiency of the roller brush 2.

[0121] In some embodiments, reference Figure 7 and Figure 8 The cover body 15 is penetrated by a jet cavity 150 , and a plurality of nozzles 120 are connected to the jet cavity 150 to spray water mist toward the roller brush 2 .

[0122] In the spray state, each nozzle 120 sprays liquid toward the jet chamber 150. At this time, the atomized liquid source can be sprayed along the jet chamber 150 onto the roller brush 2, that is, the jet chamber 150 can guide the atomized liquid source to be evenly dispersed on the roller brush 2, thereby improving the uniformity of wetting the roller brush 2.

[0123] 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.

[0124] 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 .

[0125] Regarding the specific structural design of the cover body 15, in some embodiments, refer to Figure 7 , 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 nozzle 120. In this embodiment, the number of jet chambers 150 and the number of nozzles 120 are the same as an example, that is, the multiple jet chambers 150 are spaced apart in the length direction X, and the multiple jet chambers 150 and the multiple nozzles 120 correspond to each other. This is conducive to further optimizing the guiding effect of the jet chamber 150 for each nozzle 120 and improving the uniformity of wetting the roller brush 2.

[0126] Of course, it is understandable that in other embodiments, the number of the jet chambers 150 may be less than the number of the nozzles 120 , that is, a design in which a plurality of nozzles 120 correspond to one jet chamber 150 .

[0127] In addition, in some embodiments, there may be only one jet cavity 150 , and in this case, the plurality of nozzles 120 are all connected to the same jet cavity 150 .

[0128] When the roller brush 2 and the liquid separation shell 1 are relatively fixedly installed, during the operation of the roller brush 2, when part of the bristles of the roller brush 2 rotate toward the jet chamber 150, the jet chamber 150 actually provides a space for the bristles of the roller brush 2 to lift up. Regardless of whether the cover body 15 is in contact with the roller brush 2, the jet chamber 150 can ensure that the bristles toward the nozzle 120 can lift up. At this time, when the nozzle 120 sprays liquid toward this part of the bristles, the liquid has a better penetration effect on the roller brush 2, which is beneficial to improve the uniformity and wetting effect of the roller brush 2.

[0129] Specifically, in some embodiments, referring to 3 and Figure 8 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 8 As shown, a curved surface 153 matching the cross-sectional shape of the rolling brush 2 is formed on a side of the base 151 facing away from the liquid separation member 14 .

[0130] In some embodiments, after the cover 15 and the roller brush 2 are relatively fixed, the base 151 may not be in contact with the roller brush 2, that is, there is a gap between the arc surface 153 and the roller brush 2, but it is necessary to ensure that the liquid separation portion 152 is in contact with the roller brush 2. Figure 8 As shown, the actual liquid separation portion 152 , that is, the portion of the roller brush 2 facing the spray chamber 150 , contacts the outer edge of the spray chamber 150 when the roller brush 2 rotates away from the opposite spray chamber 150 .

[0131] It is understandable that in other embodiments, the liquid separation portion 152 can also be arranged on the arc surface 153, etc., to ensure that after the roller brush 2 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 2, which will not be described in detail.

[0132] In the spray state, the roller brush 2 rotates and directs part of itself toward the jet chamber 150 to receive the liquid sprayed from the jet chamber 150, thereby wetting the roller brush 2. Subsequently, along the rotation direction W of the roller brush 2, the wetted part of the roller brush 2 is pressed and squeezed by the liquid separator 152 to disperse the liquid accumulated on the roller brush 2, thereby further improving the wetting uniformity of the roller brush 2, which is beneficial to improving the cleaning effect and cleaning efficiency of the roller brush 2.

[0133] In addition, in some embodiments, the arc surface 153 of the base 151 can also fit the roller brush 2 as a whole. At this time, the jet cavity 150 can provide a more prominent effect of lifting the bristles of the roller brush 2, and the arc surface 153 and the liquid separation portion 152 can both provide the function of pressing against the roller brush 2 to disperse the liquid on the roller brush 2.

[0134] 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 steps of the cover 15, the liquid separator 14 and the main body 13 in terms of process production 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 shell 1.

[0135] Optionally, in some embodiments, the total flow area S of the plurality of nozzles 120 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 .

[0136] By further setting the total flow area of ​​the plurality of nozzles 120 to 0.35 mm 2 Up to 1.84mm 2This is beneficial to further optimize the atomization effect of the liquid sprayed by the multiple nozzles 120 and the uniform wetting effect of the spray roller brush 2, thereby improving the cleaning effect and cleaning efficiency of the roller brush 2.

[0137] In addition, in some embodiments, the flow area S of a single nozzle 120 is 1 Meet: 0.01mm 2 ≤S 1 ≤0.16mm 2 , that is, S 1 The value 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.

[0138] In some embodiments, the distance D between adjacent nozzles 120 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 , 15.0, 15.1, 16.2, 16.3, 16.4, 16.5, 16.6, 16.7, 16.8, 16.9, 17.0, 17.1, 17.2, 17.3, 17.4, 17.5, 17.6, 17.7, 17.8, 17.9, 18.0, 18.1, 18.2, 18.3, 18.4, 18.5, and 18.6, any one of or any two of them.

[0139] In some embodiments, the number b of the spray structure 12 and its nozzles 120 satisfies: 15≤b≤33, that is, b 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.

[0140] It is necessary to reasonably arrange the number and spacing of the nozzles 120 to improve the uniformity of the liquid spraying of each nozzle 120 to the roller brush 2. If the spacing between adjacent nozzles 120 is too large, it is easy to cause insufficient coverage of the liquid spraying, while if the spacing between adjacent nozzles 120 is too small, the density of the nozzle 120 arrangement is too large, resulting in excessive cross-over of the spray coverage of adjacent nozzles 120, both of which will cause problems of uneven spraying and wetting of the roller brush 2; 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 nozzle 120 can withstand, a reasonable aperture and number of nozzles 120 are set, and the single flow area, total flow area and spacing between adjacent nozzles 120 with better uniformity in spraying and wetting the roller brush 2 can be obtained, and the flow area of ​​a single nozzle 120 is set at 0.01mm 2 Up to 0.16mm 2 Setting the distance between adjacent nozzles 120 between 6 mm and 18.6 mm, and setting the number of nozzles 120 between 15 and 33, is beneficial to further optimize the atomization effect of multiple nozzles 120 spraying water mist toward the roller brush 2 and the uniform wetting effect of spraying the roller brush 2, thereby improving the problem of water stains caused by uneven wetting of the roller brush 2 when cleaning the surface to be cleaned, and improving the cleaning efficiency of the roller brush 2.

[0141] Correspondingly, a floor brush according to an embodiment of the present application includes a liquid separation component, a roller brush 2, 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 water mist toward the roller brush 2 through the nozzle 120 and the jet chamber 150 from the liquid source pumped by the liquid pump. It can be understood that during the process of the floor brush, the liquid separation component can evenly spray water mist toward the roller brush 2, improve the uniformity of wetting the roller brush 2, improve the problem of water stains when cleaning the surface to be cleaned due to uneven wetting of the roller brush 2, and improve the cleaning efficiency of the roller brush 2.

[0142] 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.

[0143] 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 2, thereby achieving uniform wetting of the roller brush 2 and improving the cleaning effect and cleaning efficiency of the roller brush 2.

[0144] It should be noted that, in this embodiment, in combination with the length of a conventional roller brush, the dimension of the liquid separation member 14 in the length direction X is considered to be between 200 mm and 280 mm.

[0145] Based on the length of the liquid separation member 14, the number of nozzles 120 is pre-set so that the distribution density of the nozzles 120 along the length direction of the liquid separation member 14 is moderate. Considering that when the number of nozzles 120 is set to be large, each nozzle 120 is evenly distributed along the length direction X in a relatively extreme state, 35 nozzles 120 are taken for testing; considering that the actual hole diameter d of the conventional nozzle 120 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 S 1 =πd 2 / 4, it can be concluded that when the number of nozzles 120 is the largest and the diameter of the liquid spraying hole is the smallest in the limit state, S 1 Roughly 0.01mm 2 , corresponding to S is approximately 0.35mm 2 .

[0146] Based on the length of the liquid separation member 14, the number of nozzles 120 is pre-set so that the distribution density of the nozzles 120 along the length direction of the liquid separation member 14 is moderate. Considering that the number of nozzles 120 is set to be small, in a more extreme state, each nozzle 120 is evenly distributed along the length direction X, and 15 nozzles 120 are taken for testing; combined with the actual hole diameter d of the conventional nozzle 120 is 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 S 1 =πd 2 / 4, it can be concluded that when the number of nozzles 120 is the least and the diameter of the liquid spray hole is the largest in the limit state, S 1 Roughly 0.16mm 2 , corresponding to S is approximately 2.51mm 2 .

[0147] According to the above-mentioned limit state, the value can be further optimized in this embodiment to adapt to the pressure bearing capacity of the conventional liquid separation component, and the infusion pressure is preferably controlled within 1 bar. 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.

[0148] The cleaning device 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 device has the effect of atomizing the liquid source and evenly spraying the liquid source. When the floor brush is used, during the operation of the cleaning device, the liquid-separating component of the floor brush evenly sprays the atomized liquid source toward the rotating roller brush 2, thereby improving the wetting uniformity of the roller brush 2, thereby improving the problem of water stains caused by uneven wetting of the roller brush 2 when cleaning the surface to be cleaned, and improving the cleaning efficiency of the roller brush 2.

[0149] 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.

[0150] 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.

[0151] 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 into the clean liquid tank, draining liquid from the dirty liquid tank, self-cleaning and drying of the roller brush 2, 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.

[0152] The technical solution provided in the embodiments of the present application is described below in conjunction with specific implementation methods.

[0155] When the liquid separation component is used to spray liquid toward the roller brush 2, the liquid source is transported from the liquid inlet 11 to the accommodating chamber 10. Since the total flow area of ​​the multiple nozzles 120 is smaller than the flow area of ​​the liquid inlet 11, a liquid spraying pressure is formed at the nozzles 120. The liquid sprayed by the atomization of the overall spray structure 12 is helpful to increase the liquid spraying speed of the nozzles 120, expand the spraying range of the nozzles 120 toward the roller brush 2, and enhance the wetting and penetration effect on the roller brush 2. On this basis, the total flow area of ​​the multiple nozzles 120 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 the multiple nozzles 120 and the uniform wetting effect of the spray roller brush 2, improve the problem of water stains generated when cleaning the surface to be cleaned due to uneven wetting of the roller brush 2, and improve the cleaning efficiency of the roller brush 2.

Through the surrounding arrangement of each flow channel 122, the liquid in the accommodating chamber 10 is divided into two paths and input into the mixing chamber 121 to form a vortex flow, so that after being collected in the mixing chamber 121, they intersect with each other and form a vortex output toward the nozzle 120, thereby improving the effect of vortex formation in the mixing chamber 121 and improving the atomization effect of the liquid sprayed at the nozzle 120, improving the uniform wetting effect of the spray roller brush 2, reducing the problem of water stains caused by uneven wetting of the roller brush 2 when cleaning the surface to be cleaned, and improving the cleaning efficiency of the roller brush 2.

[0192] When using the cleaning device, the roller brush 2 of the floor brush is brought into contact with the surface to be cleaned, and the roller brush 2 is driven to rotate. The liquid source of the clean liquid tank is extracted by driving the liquid pump, so that the liquid source is input into the accommodating chamber 10 from the liquid inlet 11. Since the total flow area of ​​the plurality of nozzles 120 is smaller than the flow area of ​​the liquid inlet 11, a liquid spraying pressure is formed at the nozzles 120, and the liquid sprayed by the atomization of the integral spray structure 12 is helpful to increase the liquid spraying speed of the nozzles 120, expand the spraying range of the nozzles 120 toward the roller brush 2, and enhance the wetting and penetration effect on the roller brush 2. The wet roller brush 2 rolls along the surface to be cleaned, thereby quickly completing the cleaning operation.

[0193] On this basis, the total flow area of ​​the plurality of nozzles 120 is further set to 0.35 mm 2Up to 2.51mm 2 This is beneficial to further optimize the atomization effect of the liquid sprayed by the multiple nozzles 120 and the uniform wetting effect of the spray roller brush 2, thereby improving the cleaning effect and cleaning efficiency of the roller brush 2.
