Description

Technical Field

[0001] This application relates to the field of cleaning equipment technology, and more particularly to a floor brush assembly, cleaning equipment, and cleaning system. Background Technology

[0002] Cleaning equipment has advantages such as being environmentally friendly, energy-saving, and highly efficient. As people become increasingly aware of the importance of household cleaning efficiency, cleaning equipment has gradually become widely used in daily production and life.

[0003] Currently, some cleaning equipment, such as floor scrubbers, have small and non-removable solution storage tanks. When adding cleaning solution, it is necessary to add the cleaning solution to the solution storage tank of the entire floor scrubber to mix the cleaning solution with clean water to obtain the cleaning solution.

[0004] However, the cleaning equipment mentioned above requires frequent refilling of the solution storage tank due to its small capacity, and there is a risk of spillage when users add cleaning solution, which is very inconvenient. In addition, the cleaning effect is generally poor due to insufficient pressure on the ground from the rollers of the floor brush. Utility Model Content

[0005] This application provides a floor brush assembly, cleaning equipment, and cleaning system to solve the technical problems of related technologies, such as the need for frequent liquid addition due to small capacity of the cleaning equipment, the risk of spillage when adding cleaning liquid, and the mediocre cleaning effect caused by insufficient pressure of the floor brush roller on the ground.

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

[0007] Base;

[0008] A cleaning component is rotatably connected to the base, and the cleaning component is used to clean the surface to be cleaned.

[0009] A cover plate, detachably connected to the base, and located on the upper side of the cleaning component, wherein the cover plate at least partially covers the cleaning component;

[0010] The second liquid supply tank is located on the side of the cover plate away from the cleaning component, and the second liquid supply tank has a receiving cavity for containing cleaning liquid;

[0011] In the vertical direction, the orthographic projection of the second liquid supply tank onto the cleaning component overlaps with the cleaning component.

[0012] Compared with the method in related technologies where users manually add cleaning fluid to the first supply tank, the floor brush component provided in this application reduces the frequency of adding cleaning fluid by setting up an independent second supply tank, thereby improving the user experience.

[0013] Furthermore, the second liquid supply tank, which holds the cleaning solution, provides some gravity, increasing the pressure on the surface being cleaned compared to a floor brush assembly without a second tank. This enhances the stability of the floor brush assembly and indirectly helps reduce water residue, thereby improving the cleaning effect. In addition to holding cleaning solution, the second liquid supply tank can also hold water, effectively expanding the capacity of the first tank and increasing the maximum water volume.

[0014] In the aforementioned floor brush assembly, optionally, in the vertical direction, the orthographic projection area of ​​the second liquid supply tank on the cleaning component is s1, and the orthographic projection of the cleaning component on the surface to be cleaned is s2, and the relationship between s1 and s2 is: 1 / 5≤s1 / s2≤4 / 5.

[0015] With the above settings, when s1 / s2 is less than 1 / 5, the effective area covered by the second liquid supply tank is insufficient, causing the center of gravity of the second liquid supply tank to shift towards the rear of the floor brush assembly, resulting in an uneven weight distribution of the floor brush assembly and a poor operating feel. When s1 / s2 is greater than 4 / 5, the coverage area of ​​the second liquid supply tank is too large. Because the cleaning component has a certain compressibility, the floor brush assembly is prone to colliding with the wall when cleaning the area to be cleaned near the wall, causing damage to the second liquid supply tank.

[0016] In the aforementioned floor brush assembly, optionally, in the vertical direction, the orthographic projection area of ​​the second liquid supply tank on the cleaning component is s1, and the orthographic projection of the cleaning component on the surface to be cleaned is s2, and the relationship between s1 and s2 is: 1 / 2≤s1 / s2≤3 / 4.

[0017] Within this range, the cleaning component has a larger projection surface. When the second liquid supply tank is positioned on the cleaning component, its weight can be distributed evenly across different parts of the component. Therefore, the larger projection surface of the cleaning component allows for more even support of the second liquid supply tank, thus optimizing the weight distribution of the floor brush assembly, mitigating water residue issues, and ultimately improving the operational stability of the floor brush assembly and the cleaning equipment.

[0018] In the aforementioned floor brush assembly, optionally, the projection of the center of gravity of the second liquid supply tank in the vertical direction is located on the cleaning component.

[0019] The second liquid supply tank at the aforementioned location, which contains the cleaning liquid, can provide a certain amount of gravity, and with the center of gravity corresponding to the cleaning component, it can further increase the pressure of the floor brush assembly on the surface to be cleaned, thereby further enhancing the stability of the floor brush assembly and indirectly helping to alleviate water stains and residue, thus further improving the cleaning effect of the floor brush assembly on the surface to be cleaned.

[0020] In the aforementioned floor brush assembly, optionally, the cover plate includes a protective plate and a connecting plate, the protective plate is located on the upper side of the cleaning component, the protective plate is connected to the connecting plate, and the connecting plate is detachably connected to the base;

[0021] The second liquid supply tank has a first liquid outlet communicating with the receiving cavity, and the connecting plate has a second liquid outlet, which corresponds to and is connected to the first liquid outlet.

[0022] Along the extension direction of the rotation axis of the cleaning component, the first liquid outlet is located in the middle area of ​​the second liquid supply tank, and the second liquid outlet is located in the middle area of ​​the connecting plate.

[0023] With the above configuration, the cleaning fluid in the second supply tank can flow evenly to the first outlet, and then enter the working area of ​​the cleaning component through the second outlet, which helps to distribute the cleaning fluid evenly on the component. When the cleaning component rotates, the evenly distributed cleaning fluid can be effectively carried into the area where the component contacts the surface to be cleaned, thereby improving the cleaning effect and avoiding the problem of local water stains caused by uneven distribution of cleaning fluid. This further enhances the cleaning capability of the cleaning equipment and improves the user experience.

[0024] Optionally, in the aforementioned floor brush assembly, the base has a suction port, which is located close to the cleaning component;

[0025] With the rotation axis of the cleaning component as the axis, the first liquid outlet, the second liquid outlet, and the suction port are arranged on the same side.

[0026] With the above configuration, the first and second liquid outlets are located on the same side, ensuring that the cleaning solution is sprayed evenly onto the area where the cleaning component contacts the surface to be cleaned, avoiding waste caused by spraying the cleaning solution onto non-clean areas. Simultaneously, the suction port is located on the same side as the first and second liquid outlets, allowing for timely collection of cleaned contaminants.

[0027] If the first liquid outlet, the second liquid outlet, and the suction port are located on different sides, that is, the spraying direction of the cleaning liquid is opposite to the suction direction, the cleaning liquid may be sucked into the suction port in advance, affecting the cleaning effect.

[0028] Optionally, in the aforementioned floor brush assembly, the base has an inlet corresponding to the second liquid outlet, and a sealing ring is provided between any two of the inlet, the second liquid outlet, and the first liquid outlet.

[0029] The sealing ring effectively prevents cleaning fluid from leaking at the interface, ensuring that the cleaning fluid does not overflow during transportation, preventing it from spilling into unwanted areas, ensuring that all cleaning fluid is used for cleaning operations, avoiding waste, and also helping to maintain the efficient operation of the equipment.

[0030] Optionally, the floor brush assembly described above may also include an inlet pipe, a pump, a mixing pipe, and a liquid distribution component. The inlet pipe is connected to the second supply tank and the input end of the pump, respectively. The output end of the pump is connected to the mixing pipe. The pump is used to draw cleaning liquid from the second supply tank and deliver it to the mixing pipe.

[0031] The input end of the mixing pipe can also be connected to the first liquid supply tank of the cleaning equipment, and the output end of the mixing pipe can be connected to the liquid distribution component. The liquid distribution component can distribute the cleaning solution after the cleaning liquid and clean water are mixed to the cleaning component.

[0032] With the above setup, the cleaning solution can be mixed with the clean water in the first supply tank after entering the mixing pipe, providing the necessary mixture of cleaning solution and clean water for cleaning operations. The mixing process can be adjusted according to cleaning needs to improve the cleaning effect.

[0033] Optionally, in the aforementioned floor brush assembly, the protective plate and the connecting plate are integrated as a single unit.

[0034] First, during the operation of the cleaning equipment, the cover plate needs to withstand a certain amount of external force and pressure. The one-piece design can avoid structural damage caused by weak points at the joints, which can enhance the overall structural strength of the cover plate and thus improve its durability.

[0035] Secondly, the integrated design reduces the processing and assembly steps of individual components, simplifying the production process and lowering production costs. Simultaneously, during assembly, no additional connectors are needed to secure the protective and connecting plates, improving assembly speed and accuracy. Furthermore, the integrated design effectively prevents cleaning fluid leakage at the joints, reduces gaps between components, and avoids cleaning fluid waste.

[0036] In the aforementioned floor brush assembly, optionally, the second liquid supply tank includes a housing having the receiving cavity;

[0037] The box body is bonded to the cover plate, or the box body and the cover plate are an integral part.

[0038] Through the above-described design, the box body and cover are bonded together, forming a tight seal to prevent cleaning fluid leakage and ensure the safe storage and stable supply of the cleaning fluid within the box. The box body and cover are integrated, enhancing their overall integrity and structural strength, preventing structural damage due to weak points at the connection, and improving the durability of the second fluid supply tank. Furthermore, the integrated design reduces assembly steps in the manufacturing process, lowering production costs and increasing production efficiency.

[0039] Optionally, the floor brush assembly described above may also include a locking component and a releasing component, wherein the locking component is connected to the releasing component;

[0040] The fixed end of the locking member is elastically connected to one of the cover plate and the second liquid supply tank, the movable end of the locking member is used to engage with the base, and the release member is used to move the movable end closer to the fixed end.

[0041] The flexible connection allows the locking element some room to deform under external force, and it returns to its original shape when the force is removed. This flexible connection also ensures a tight contact between the locking element and the cover or second liquid supply tank, enhancing sealing and preventing cleaning fluid leakage. When the user applies external force to release the locking element to install or remove the second liquid supply tank, the locking element returns to its locked state without manual operation, improving user convenience.

[0042] Optionally, in the aforementioned floor brush assembly, the second liquid supply tank also has a liquid inlet communicating with the receiving cavity, the liquid inlet being located on the side of the second liquid supply tank opposite to the cleaning component.

[0043] The presence of the injection port allows users to add cleaning fluid to the receiving cavity at any time without disassembling the entire second supply tank or other components, facilitating fluid replenishment. Furthermore, the injection port ensures that the cleaning equipment can be replenished with cleaning fluid promptly during use, guaranteeing the continuity of cleaning operations.

[0044] Optionally, in the above-mentioned floor brush assembly, the second liquid supply tank further includes a switch door, which is rotatably connected to the second liquid supply tank and is used to cover or open the liquid inlet.

[0045] A one-way valve is provided on the side of the switch door facing the second liquid supply tank;

[0046] When the switch door covers the injection port, the one-way valve blocks the injection port to allow one-way flow from the outside of the second liquid supply tank to the receiving cavity.

[0047] In this way, on the one hand, the cleaning fluid can be prevented from leaking due to vibration or other external forces during the use of the cleaning equipment, and on the other hand, outside air and pollutants can be prevented from entering the receiving cavity through the injection port, thereby ensuring the cleanliness of the cleaning fluid and the normal operation of the cleaning equipment.

[0048] Secondly, this application also provides a cleaning device, including a body and the aforementioned floor brush assembly, the floor brush assembly being located on the body.

[0049] Optionally, the cleaning equipment described above may also include a first liquid supply tank, which is disposed on the floor brush assembly or the machine body, and the first liquid supply tank is connected to the mixing pipe of the floor brush assembly.

[0050] Thirdly, embodiments of this application also provide a cleaning system, including the cleaning equipment and a base station or base that cooperates with it.

[0051] Compared with the method in related technologies where users manually add cleaning fluid to the first supply tank, the floor brush assembly, cleaning equipment, and cleaning system provided in this application embodiment have an independently set second supply tank, which reduces the frequency of users adding cleaning fluid and improves the user experience.

[0052] Furthermore, the second liquid supply tank, which holds the cleaning solution, provides some gravity, increasing the pressure on the surface being cleaned compared to a floor brush assembly without a second supply tank. This enhances the stability of the floor brush assembly and indirectly helps reduce water residue, thereby improving the cleaning effect. In addition to holding the cleaning solution, the second solution tank can also hold clean water, effectively expanding the capacity of the first supply tank and increasing the maximum volume of clean water.

[0053] In addition, the center of gravity of the second liquid supply tank in the vertical direction is located on the cleaning component, which can further increase the pressure of the floor brush assembly on the cleaning surface, thereby further improving the cleaning effect of the floor brush assembly on the cleaning surface.

[0054] Then, the second liquid supply tank has a larger projection surface. The cleaning components with a larger projection surface can support the second liquid supply tank more evenly, thereby optimizing the weight distribution of the floor brush assembly, alleviating the problem of water stain residue, and thus improving the working stability of the floor brush assembly and cleaning equipment.

[0081] The technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, and not all embodiments. Based on the embodiments of this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application.

[0082] In a first aspect, embodiments of this application provide a cleaning system (not shown in the figures), including a base or base station, and a cleaning device placed on the base or base station for cooperation.

[0083] Understandably, after cleaning the surface, the cleaning equipment can be placed on a base or base station for positioning, charging, self-cleaning, drying, or water supply and drainage. The base or base station has designated placement positions for the cleaning equipment, allowing for its accurate positioning. A charging port is also provided on the base or base station for charging the cleaning equipment. The base station may have an inlet pipe and a drain pipe to supply water to the first liquid supply tank and drain the wastewater tank. A drying device may be installed on the base or base station to dry the cleaned equipment.

[0084] It should be noted that the base or base station generally needs to be placed on the ground to support the operation of the cleaning equipment.

[0085] Secondly, this application also provides a cleaning device, which includes a body and a floor brush assembly, with the floor brush assembly located on the body.

[0086] It is understood that the floor brush assembly is located on the main body of the machine and can be used to perform cleaning actions on the surface to be cleaned to achieve a cleaning effect. The surface to be cleaned can be a floor or wall surface with varying degrees of roughness, or a carpet or rug of different lengths or types, or the surface of an object to be cleaned. This application does not specifically limit the type of surface to be cleaned. The cleaning action can be vacuuming, mopping, or both simultaneously to ensure the cleaning efficiency of the machine.

[0087] Furthermore, a suction channel can be set in the body, which can be connected to the vicinity of the floor brush assembly, so that external dirt can enter the suction channel after being cleaned by the floor brush assembly, thereby completing the cleaning work.

[0088] Reference Figure 1As an optional implementation, the cleaning equipment also includes a first liquid supply tank 20, which is installed on the floor brush assembly 10 or the machine body. The first liquid supply tank 20 can provide clean water for cleaning the floor brush assembly 10. The first liquid supply tank 20 is connected to the mixing pipe 700 of the floor brush assembly 10, that is, clean water can be connected to the floor brush assembly 10 through the mixing pipe 700.

[0089] Furthermore, the cleaning equipment also includes a wastewater tank, which can be mounted on the floor brush assembly 10 or on the machine body. The wastewater tank is connected to the suction channel to store the collected waste.

[0090] In this embodiment, the first liquid supply tank 20 is disposed on the floor brush assembly 10.

[0091] Reference Figure 1 Thirdly, this application embodiment also provides a floor brush assembly 10, which includes a base 100, a cleaning component 200, a cover plate 300, and a second liquid supply tank 400.

[0092] Specifically, the base 100 has a suction port 110, which connects to the suction channel of the machine body. The suction port 110 can be used to suck up substances, which may include liquids or solids such as hair and dust. It should be noted that the shape of the suction port 110 can be arbitrary, such as circular, square, or irregular, and can be varied according to requirements. This embodiment will not be elaborated here.

[0093] The cleaning component 200 is rotatably connected to the base 100 and is used to clean the surface to be cleaned. It is understood that the type of the cleaning component 200 can be arbitrary. For example, the cleaning component 200 can be a roller brush, a rag, a conveyor belt, etc. This application embodiment does not limit the specific type of the cleaning component 200, nor is it limited to the above examples. The following description uses a roller brush as an example of the cleaning component 200.

[0094] The cleaning component 200 has bristles on its outer periphery for cleaning. The bristles can move dirt on the surface to be cleaned. As the cleaning component 200 rotates, the dirt can be rotated until it is attracted by the suction channel located nearby, thus completing the cleaning of the dirt. It should be noted that the bristles can be soft or hard. This application embodiment does not limit the bristles of the cleaning component 200, nor is it limited to the above example.

[0095] It is understood that the dirt that the cleaning component 200 can carry includes, but is not limited to, hair, debris, liquids, etc. The embodiments of this application do not limit the usage scenarios of the cleaning component 200, nor are they limited to the above examples.

[0096] By setting up the cleaning component 200, the cleaning component 200 can be used to clean the surface to be cleaned, so as to complete the cleaning function of the cleaning equipment and the cleaning system; by using the rotatable cleaning component 200, the cleaning function of the cleaning component 200, the cleaning equipment and the cleaning system can be realized.

[0097] The cover plate 300 and the base 100 are detachably connected. It is understood that the detachable connection between the cover plate 300 and the base 100 may include, but is not limited to, snap-fit, screw-fit, adhesive, etc. The embodiments of this application do not limit the specific connection method between the cover plate 300 and the base 100, nor are they limited to the above examples.

[0098] With the above-mentioned configuration, the detachable connection allows the cover plate 300 to be removed during installation and maintenance, making it convenient to clean, replace or repair the cover plate 300 and other components such as the cleaning parts 200, reducing maintenance costs and difficulty, and also reducing the risk of cleaning fluid spillage when adding cleaning fluid, thus providing convenience for users.

[0099] The cover plate 300 is located on the upper side of the cleaning component 200 and covers part of the cleaning component 200. The cover plate 300 can protect the cleaning component 200 and prevent it from being contaminated by external dust and debris when not in use, or from being damaged by collisions with other objects during movement or storage, thereby extending the service life of the cleaning component 200.

[0100] The second liquid supply tank 400 is located on the side of the cover plate 300 away from the cleaning component 200, which avoids the second liquid supply tank 400 occupying a large space, improves the utilization rate of the internal space of the floor brush assembly 10, and is conducive to the miniaturization of the floor brush assembly 10, and thus to the miniaturization of the cleaning equipment and cleaning system.

[0101] The second liquid supply tank 400 has a receiving cavity 410 for holding cleaning fluid, which makes it more convenient for users to add or replace cleaning fluid without disassembling too many parts, thus improving ease of use.

[0102] Since the second liquid supply tank 400 is located on the side of the cover plate 300 away from the cleaning component 200, the user can directly open the second liquid supply tank 400 to replenish the cleaning fluid, which makes it convenient for the user to use.

[0103] It is understandable that, compared with the method in related technologies where users manually add cleaning fluid to the first supply tank, the floor brush assembly 10 provided in this application embodiment reduces the frequency of users adding cleaning fluid by setting up an independent second supply tank 400, thereby improving the user experience.

[0104] Reference Figure 3In the vertical direction Z, the orthographic projection of the second liquid supply tank 400 onto the cleaning component 200 overlaps with that of the cleaning component 200. The weight of the second liquid supply tank 400 and the cleaning component 200 are reasonably distributed in the vertical direction Z, which prevents the center of gravity of the floor brush assembly 10 from being too far back, thus making the floor brush assembly 10 more stable during operation. This improves the stability of the cleaning equipment and system, facilitates user operation, and enhances user comfort and convenience.

[0105] With the above configuration, the second liquid supply tank 400 that contains the cleaning liquid can provide a certain amount of gravity. Compared with the floor brush assembly 10 without the second liquid supply tank 400, the pressure of the floor brush assembly 10 on the surface to be cleaned can be increased, which can enhance the stability of the floor brush assembly 10 and indirectly help to alleviate water stains and residues, thereby improving the cleaning effect of the floor brush assembly 10 on the surface to be cleaned.

[0106] It should be noted that the second liquid supply tank 400 can also hold clean water. In this case, the second liquid supply tank 400 can be used as an expansion of the first liquid supply tank 20 to increase the upper limit of the clean water volume.

[0107] Reference Figure 3 As an optional implementation, in the vertical direction Z, the orthographic projection area of ​​the second liquid supply tank 400 on the cleaning component 200 is s1, and the orthographic projection of the cleaning component 200 on the surface to be cleaned is s2, where s1 is less than s2.

[0108] Specifically, when the projected area s1 of the second liquid supply tank 400 on the cleaning component 200 is smaller than the projected area s2 of the cleaning component 200 on the surface to be cleaned, the second liquid supply tank 400 can be prevented from extending from the front side of the floor brush assembly 10 or from being on the same plane as the cleaning component 200 in the vertical direction Z. This avoids the second liquid supply tank 400 from hitting the wall first or hitting the wall at the same time as the cleaning component 200 when in operation, reducing cleaning dead corners, effectively increasing the cleanable area, and preventing the second liquid supply tank 400 from being damaged when it touches the wall.

[0109] Furthermore, the relationship between s1 and s2 is: 1 / 5 ≤ s1 / s2 ≤ 4 / 5.

[0110] When s1 / s2 is less than 1 / 5, the effective area covered by the second liquid supply tank 400 and the cleaning component 200 is insufficient, causing the center of gravity of the second liquid supply tank 400 to shift towards the rear of the floor brush assembly 10. This results in an uneven weight distribution of the floor brush assembly 10 and a poor operating feel. When s1 / s2 is greater than 4 / 5, the coverage area of ​​the second liquid supply tank 400 is too large. Because the cleaning component 200 has a certain compressibility, the floor brush assembly 10 is prone to colliding with the wall when cleaning the area to be cleaned near the wall, causing damage to the second liquid supply tank 400.

[0111] As an optional implementation, in the vertical direction Z, the orthographic projection area of ​​the second liquid supply tank 400 on the cleaning component 200 is s1, and the orthographic projection of the cleaning component 200 on the surface to be cleaned is s2. The relationship between s1 and s2 is: 1 / 2≤s1 / s2≤3 / 4.

[0112] It should be noted that the second liquid supply tank 400, which contains the cleaning fluid, has a relatively high weight, while the cleaning component 200 has a large projection surface. When the second liquid supply tank 400 is positioned on the cleaning component 200, its weight can be distributed evenly across different locations within the component. Therefore, the larger projection surface of the cleaning component 200 allows for a more uniform support of the second liquid supply tank 400, thus optimizing the weight distribution of the floor brush assembly 10 and improving the operational stability of both the floor brush assembly 10 and the cleaning equipment.

[0113] As an alternative implementation, in the vertical direction Z, the projection of the center of gravity of the second liquid supply tank 400 is located on the cleaning component 200.

[0114] It is understandable that the center of gravity of the second liquid supply tank 400 changes depending on the liquid distribution within the second liquid supply tank 400, such as the center of gravity of the second liquid supply tank 400 being located on the side with more liquid.

[0115] The second liquid supply tank 400 at the aforementioned location can provide a certain amount of gravity, and the center of gravity is located on the cleaning component 200. This can further increase the pressure of the floor brush assembly 10 on the surface to be cleaned, thereby further enhancing the stability of the floor brush assembly 10 and indirectly helping to alleviate water stains and residues, thus further improving the cleaning effect of the floor brush assembly 10 on the surface to be cleaned.

[0116] Reference Figure 4 and Figure 5 As an optional implementation, the cover plate 300 includes a protective plate 310 and a connecting plate 320.

[0117] Specifically, the protective plate 310 can effectively cover and protect the cleaning component 200. During movement or storage, the protective plate 310 prevents the cleaning component 200 from being damaged by collisions with other objects, thereby extending the service life of the cleaning component 200.

[0118] In some embodiments, the protective plate 310 is located on top of the cleaning component 200. During operation, the rotating cleaning component 200 of the floor brush assembly 10 splashes liquid. The protective plate 310 located on top of the cleaning component 200 can block the splashed liquid and prevent it from contaminating the surface to be cleaned.

[0119] The protective plate 310 is connected to the connecting plate 320, and the connecting plate 320 is detachably connected to the base 100. By incorporating this detachable design, users can easily remove the cover plate 300 to clean, replace, or repair components such as the cover plate 300 and the cleaning component 200, thereby reducing maintenance costs.

[0120] In addition, the detachable design helps reduce the risk of liquid spillage when adding cleaning solution, providing users with a more convenient user experience.

[0121] Reference Figure 4 and Figure 5 Furthermore, the second liquid supply tank 400 has a first liquid outlet 420 communicating with the receiving cavity 410, and the connecting plate 320 has a second liquid outlet 321, which corresponds to and communicates with the first liquid outlet 420. That is, the cleaning fluid in the second liquid supply tank 400 can be moved out of the second liquid supply tank 400 through the first liquid outlet 420 and the second liquid outlet 321, ensuring that the cleaning fluid can flow out of the second liquid supply tank 400 smoothly.

[0122] It should be noted that the shape and size of the first liquid outlet 420 and the second liquid outlet 321 can be adjusted according to requirements, and the shape and size of the first liquid outlet 420 and the second liquid outlet 321 can be the same or different. For example, the first liquid outlet 420 and the second liquid outlet 321 can be circular holes; another example is that the first liquid outlet 420 is square and the second liquid outlet 321 is circular, etc. This application does not limit the specific shape and size of the first liquid outlet 420 and the second liquid outlet 321, nor is it limited to the above examples.

[0123] The following explanation uses the example of the first liquid outlet 420 and the second liquid outlet 321 both being circular holes.

[0124] Along the extension direction of the rotation axis of the cleaning component 200, i.e. along the horizontal direction X, the first liquid outlet 420 is located in the middle area of ​​the second liquid supply tank 400, and the second liquid outlet 321 is located in the middle area of ​​the connecting plate 320, i.e., the positions of the first liquid outlet 420 and the second liquid outlet 321 are corresponding.

[0125] Through the first liquid outlet 420 and the second liquid outlet 321 located in the middle area, the cleaning liquid in the second liquid supply tank 400 can flow evenly to the first liquid outlet 420, and then be moved out of the second liquid supply tank 400 through the second liquid outlet 321. This position corresponds to the working area of ​​the cleaning component 200, which helps the cleaning liquid to be evenly distributed on the cleaning component 200.

[0126] Furthermore, when the cleaning component 200 rotates, the evenly distributed cleaning fluid can be effectively carried into the area where the cleaning component 200 contacts the surface to be cleaned, thereby improving the cleaning effect and avoiding the problem of local water stains caused by uneven distribution of cleaning fluid, further enhancing the cleaning ability of the cleaning equipment and thus improving the user experience.

[0127] As described above, the base 100 has a suction port 110. As an optional implementation, the suction port 110 is located close to the cleaning component 200, that is, the suction port 110 can quickly collect dirt, including dust, hair, liquid, etc., after the cleaning component 200 has cleaned it.

[0128] Understandably, the cleaning component 200, during its rotation, can move and rotate the dirt on the surface to be cleaned. When the suction port 110 approaches the cleaning component 200, the dirt can be quickly sucked in and transferred to the suction channel, thereby reducing the time and amount of dirt remaining around the cleaning component 200, thus improving the cleaning effect. For example, when the cleaning component 200 is a roller brush, the bristles on the roller brush gather the dirt and, as the roller brush rotates, move it to the vicinity of the suction port 110. The suction port 110 can then suck in the dirt and transfer it to the suction channel, achieving the cleaning of the surface to be cleaned.

[0129] Reference Figure 4 and Figure 5 With the rotation axis of the cleaning component 200 as the axis, the first liquid outlet 420, the second liquid outlet 321, and the suction port 110 are arranged on the same side. "Arranged on the same side" means they are located on both sides of the rotation axis of the cleaning component 200, such as both on the front side or both on the rear side. It is understood that this arrangement facilitates precise spraying of the cleaning liquid and collection of dirt, improving the cleaning effect of the cleaning equipment, while also enhancing its stability and reliability.

[0130] Specifically, the first liquid outlet 420 and the second liquid outlet 321 are located on the same side, which ensures that the cleaning fluid can be evenly discharged from the second liquid supply tank 400, so as to spray it on the area where the cleaning component 200 contacts the surface to be cleaned, avoiding waste caused by the cleaning fluid being sprayed on non-clean areas. At the same time, the suction port 110 is located on the same side as the first liquid outlet 420 and the second liquid outlet 321, so that the suction port 110 can collect the dirt after cleaning in a timely manner.

[0131] It should be noted that if the first liquid outlet 420, the second liquid outlet 321, and the suction port 110 are located on different sides, that is, the spraying direction of the cleaning liquid is opposite to the suction direction, the cleaning liquid may be sucked into the suction port 110 in advance, affecting the cleaning effect.

[0132] Reference Figure 5 and Figure 6As an optional implementation, the base 100 has an inlet 120 corresponding to the second outlet 321. The inlet 120 corresponds to the second outlet 321, which can ensure that the cleaning fluid flows steadily and smoothly from the second supply tank 400 into the connecting plate 320 and reaches the cleaning area of ​​the cleaning component 200.

[0133] Specifically, the second liquid supply tank 400 stores cleaning fluid, which is released through the first liquid outlet 420 to the second liquid outlet 321 of the connecting plate 320. The liquid inlet 120 on the base 100 corresponds to the second liquid outlet 321, forming a complete fluid channel, allowing the cleaning fluid to flow smoothly from the second liquid supply tank 400 into the area near the cleaning component 200, thereby improving the delivery efficiency of the cleaning fluid.

[0134] Furthermore, a sealing ring is provided between any two of the liquid inlet 120, the second liquid outlet 321, and the first liquid outlet 420.

[0135] Understandably, the sealing ring can effectively prevent cleaning fluid from leaking at the interface, ensuring that the cleaning fluid does not overflow during the delivery process, preventing the cleaning fluid from spilling into unwanted areas, ensuring that the cleaning fluid is used entirely for cleaning operations, avoiding waste, and also helping to maintain the efficient operation of the cleaning equipment.

[0136] Reference Figure 2 As an optional implementation, the floor brush assembly 10 also includes an inlet pipe 500, a liquid pump 600, a mixing pipe 700, and a liquid distribution component 800.

[0137] Specifically, the inlet pipe 500 is connected to the second supply tank 400. As described above, the second supply tank 400 is connected to the inlet 120 through the first outlet 420 and the second outlet 321, that is, the inlet pipe 500 is connected to the inlet 120, to ensure that the cleaning fluid can smoothly enter the inlet pipe 500 after flowing out of the second supply tank 400, providing a basis for subsequent cleaning fluid distribution and mixing.

[0138] The liquid pump 600 has an input end and an output end. The inlet pipe 500 connects the inlet port 120 to the input end of the liquid pump 600, allowing the liquid pump 600 to use its suction function to draw cleaning fluid from the second supply tank 400. This ensures that the delivery of cleaning fluid does not rely on gravity or other passive methods, improving the reliability and efficiency of the cleaning fluid supply. In other words, the liquid pump 600 can ensure precise distribution of the cleaning fluid, allowing it to be supplied to the mixing pipe 700 as needed.

[0139] The output end of the liquid pump 600 is connected to the input end 710 of the mixing pipe 700, allowing the cleaning liquid to enter the mixing pipe 700 directly from the liquid pump 600. At the same time, the input end 710 of the mixing pipe 700 can also be connected to the first liquid supply tank 20 of the cleaning equipment, allowing clean water to enter the mixing pipe 700.

[0140] It is understandable that the output end of the liquid pump 600 can be connected to the liquid outlet pipe 610, which is connected to the input end of the mixing pipe 700. The liquid outlet pipe 610 is used to transfer the cleaning liquid received by the liquid pump 600 to the input end 710 of the mixing pipe 700.

[0141] Specifically, the clean water in the first supply tank 20 is drawn into the clean water pump 23 through the inlet pipe 21 and flows to the inlet 710 of the mixing pipe 700 through the outlet pipe 22. In this way, both cleaning fluid and clean water can flow into the inlet 710 of the mixing pipe 700, which mixes the cleaning fluid and clean water. This allows the cleaning fluid to mix with the clean water in the first supply tank 20 after entering the mixing pipe 700, providing the necessary mixture of cleaning fluid and clean water, i.e., the cleaning solution, for cleaning operations. It should be noted that the ratio of cleaning fluid to clean water can be adjusted according to cleaning needs to improve the cleaning effect.

[0142] Furthermore, the output end 720 of the mixing pipe 700 can be connected to the liquid distribution component 800. The liquid distribution component 800 can distribute the liquid output from the mixing pipe 700, i.e. the cleaning liquid after mixing the cleaning liquid and clean water, to the cleaning component 200. The cleaning liquid contacts the cleaning component 200 so that the cleaning component 200 can complete self-cleaning or the cleaning component 200 can clean the surface to be cleaned.

[0143] Understandably, attached Figure 2 The pipes shown only illustrate the connection relationship and do not restrict the specific shape.

[0144] As an optional implementation, the protection plate 310 and the connecting plate 320 are integrated into one piece.

[0145] First, during the operation of the cleaning equipment, the cover plate 300 needs to withstand certain external forces and pressures. The integrated component can avoid structural damage caused by weak points at the connection, which can enhance the overall structural strength of the cover plate 300 and thus improve its durability.

[0146] Secondly, the integrated design reduces the processing and assembly steps of individual components, simplifying the production process and lowering production costs. Simultaneously, during assembly, no additional connectors are needed to secure the protective plate 310 and connecting plate 320, improving assembly speed and accuracy. Furthermore, the integrated design effectively prevents cleaning fluid leakage from the joints, reduces gaps between components, and avoids cleaning fluid waste.

[0147] Reference Figure 7 As an optional implementation, the second liquid supply tank 400 includes a housing 430 having a receiving cavity 410, in which the cleaning fluid can be stored.

[0148] During the operation of the cleaning equipment, cleaning fluid is drawn from the receiving cavity 410 and released onto the cleaning component 200 through the outlet, ensuring continuous cleaning operations. It should be noted that the capacity and shape design of the receiving cavity 410 can be optimized according to the usage requirements of the cleaning equipment to meet the cleaning fluid needs in different scenarios.

[0149] In some embodiments, the housing 430 is bonded to the cover 300. This creates a tight seal between the housing 430 and the cover 300, preventing leakage of the cleaning fluid and ensuring its safe storage and stable supply within the housing 430.

[0150] In some other embodiments, the housing 430 and the cover 300 are integrated as a single unit. This integrated design enhances the overall integrity and structural strength of the housing 430 and the cover 300, preventing structural damage caused by weak points at the connection points and improving the durability of the second liquid supply tank 400. Furthermore, the integrated design reduces assembly steps in the manufacturing process, lowers production costs, and increases production efficiency.

[0151] Reference Figure 8 As an optional implementation, the floor brush assembly 10 also includes a locking member 910 and a releasing member 920, wherein the fixed end of the locking member 910 is elastically connected to one of the cover plate 300 and the second liquid supply tank 400, and the movable end of the locking member 910 is used for snap-fit ​​connection with the base 100.

[0152] For example, the fixed end of the locking member 910 is elastically connected to the cover plate 300, and the movable end of the locking member 910 is engaged with the base 100 to load and unload the second liquid supply tank 400. In another example, the fixed end of the locking member 910 is elastically connected to the second liquid supply tank 400, and the movable end of the locking member 910 is engaged with the base 100 to load and unload the second liquid supply tank 400.

[0153] The locking element 910 is connected to the releasing element 920. When the user operates the releasing element 920, the releasing element 920 drives the locking element 910 to move, ensuring that the locking element 910 can accurately complete the locking or releasing action.

[0154] It should be noted that the elastic connection allows the locking element 910 a certain amount of deformation space when subjected to external force, and it can return to its original shape when the external force is removed. In this way, the elastic connection also ensures a tight contact between the locking element 910 and the cover plate 300 or the second liquid supply tank 400, enhancing sealing and preventing cleaning fluid leakage. When the user applies external force to release the locking element 910 to install or remove the second liquid supply tank 400, the locking element 910 returns to its locked state without manual operation, improving user convenience.

[0155] Furthermore, the snap-fit ​​connection refers to the interaction between the movable end of the locking element 910 and the slot or buckle on the base 100, which enables quick locking. It is understood that the above connection method does not require complex installation steps; the user only needs to apply a certain pressure to the movable end of the locking element 910 to make it snap into the slot of the base 100, thus completing the locking process.

[0156] The release element 920 is used to move the movable end closer to the fixed end. That is, the release element 920 can move towards the fixed end of the locking element 910 via mechanical transmission or direct action, thereby releasing the engagement with the base 100. This design allows the user to unlock the cover 300 simply by operating the release element 920, without applying excessive force or performing complex operations, thus improving the user experience.

[0157] As an optional implementation, the second liquid supply tank 400 also has a liquid inlet (not shown) communicating with the receiving cavity 410.

[0158] Understandably, the receiving cavity 410 of the second supply tank 400 is used to store cleaning fluid, which will be gradually consumed during the operation of the cleaning equipment. The presence of the filling port allows the user to add cleaning fluid to the receiving cavity 410 at any time without disassembling the entire second supply tank 400 or other components, facilitating the replenishment of cleaning fluid. In addition, the filling port ensures that the cleaning equipment can be replenished with cleaning fluid in a timely manner during use, guaranteeing the continuity of cleaning work.

[0159] The liquid inlet is located on the side of the second liquid supply tank 400 away from the cleaning component 200, so that when adding cleaning fluid, the user does not need to come into contact with the cleaning component 200 and the base 100, thus avoiding potential contamination of the cleaning component 200 and the base 100 during the addition process.

[0160] Understandably, this layout, which keeps the injection port away from the working area of ​​the cleaning component 200, reduces the risk of accidental leakage of cleaning fluid onto the cleaning component 200 or the base 100 during the addition process. This improves the reliability and cleaning effect of the floor brush assembly 10 and the cleaning equipment. Simultaneously, users have more operating space and lower operational difficulty when adding cleaning fluid, enhancing both convenience and safety.

[0161] Reference Figure 7 As an optional implementation, the second liquid supply tank 400 also includes a switch door 440, which is rotatably connected to the second liquid supply tank 400. The switch door 440 is used to cover or open the liquid inlet. Through the switch door 440, the user can open or close the liquid inlet simply by rotating the switch door 440. This rotation method is simple and easy to operate, requiring no disassembly or installation of additional parts, thus improving the efficiency and convenience of user operation.

[0162] For example, when no cleaning fluid is being added, the switch door 440 can seal the inlet to prevent cleaning fluid leakage and the entry of external contaminants. Alternatively, when cleaning fluid needs to be added, the user can rotate the switch door 440 to open the inlet, thereby releasing the inlet and allowing the cleaning fluid to be added.

[0163] A one-way valve 450 is provided on the side of the switch door 440 facing the second liquid supply tank 400. The one-way valve 450 ensures that the cleaning fluid can only flow into the receiving cavity 410 from the injection port, preventing the cleaning fluid from flowing out in reverse and improving the sealing and reliability of the second liquid supply tank 400.

[0164] Specifically, a one-way valve 450 is installed on the side of the switch door 440 facing the second supply tank 400. When the switch door 440 covers the injection port, the one-way valve 450 automatically seals the injection port. The one-way valve 450 ensures that the cleaning fluid can only flow into the receiving cavity 410 from the injection port and cannot flow out in the opposite direction. In this way, on the one hand, it can prevent the cleaning fluid from leaking due to vibration or other external forces during the use of the cleaning equipment, and on the other hand, it can prevent outside air and contaminants from entering the receiving cavity 410 through the injection port, thereby ensuring the cleanliness of the cleaning fluid and the normal operation of the cleaning equipment.

[0165] Furthermore, when the opening and closing door 440 covers the injection port, the one-way valve 450 blocks the injection port to allow the outer side of the second liquid supply tank 400 to unidirectionally flow into the receiving cavity 410.

[0166] Specifically, when the opening / closing door 440 covers the injection port, the one-way valve 450 is pressed tightly against the injection port by the opening / closing door 440, forming a seal. This seal ensures that the cleaning fluid can only flow into the receiving cavity 410 from the injection port, thus forming one-way flow.

[0167] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this application, and are not intended to limit them. Although this application has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some or all of the technical features therein.
