Description

Technical Field

[0001] This utility model relates to the field of cleaning tools technology, and specifically to a cleaning device. Background Technology

[0002] Currently, cleaning various surfaces is essential in daily life and industrial production. For example, windows, glass curtain walls, walls, and the surfaces of various equipment often accumulate dust, stains, and water stains, requiring cleaning to maintain their cleanliness and good visual appearance, while also helping to extend the lifespan of the cleaned objects.

[0003] However, while existing cleaning devices improve cleaning efficiency to some extent, they often have shortcomings in liquid collection and guidance. During the cleaning process, especially when cleaning vertical surfaces, the wastewater flowing down after cleaning can easily re-contaminate the cleaned area.

[0004] Therefore, how to provide a cleaning device that can effectively collect the liquid generated during the cleaning process has become a technical problem that urgently needs to be solved by those skilled in the art. Utility Model Content

[0005] In view of this, the present invention provides a cleaning device to solve the problem of collecting and guiding liquid generated during the cleaning process in existing cleaning devices.

[0006] In a first aspect, this utility model provides a cleaning device, comprising:

[0007] Liquid collection structure;

[0008] The cleaning head is equipped with a scraper and a collection port. The scraper and the collection port are positioned correspondingly so that the scraper can guide the liquid on the surface to be cleaned into the collection port. The collection port is connected to the collection structure. When the cleaning head cleans the surface to be cleaned from bottom to top, the extension direction of the scraper has an angle with the horizontal direction so that the collection port is located below at least one end of the scraper, thereby enabling the scraper to guide the liquid on the surface to be cleaned into the collection port and then into the collection structure.

[0009] Beneficial effects: In this application, the scraper and the liquid collection port are positioned correspondingly, and when the cleaning head cleans from bottom to top, the extension direction of the scraper makes an angle with the horizontal direction, so that the liquid collection port is located below at least one end of the scraper. This design allows the liquid on the surface to be cleaned to flow along the scraper into the liquid collection port under the action of gravity during the cleaning process, thereby collecting the liquid in the liquid collection structure. Furthermore, when the cleaning structure of this application cleans from bottom to top, the scraper guides the liquid on the surface to be cleaned into the liquid collection port; at this time, the scraper contacts the surface to be cleaned, which can prevent the liquid on the surface to be cleaned from flowing to the lower side of the scraper under the action of gravity, thus affecting the collection effect.

[0010] Furthermore, the cleaning head is provided with a protruding liquid collecting nozzle, which has an inlet and an outlet connecting to the liquid collecting structure; the inlet has an expansion port, which forms a liquid collecting port; when the scraper scrapes the surface to be cleaned, there is a gap between the liquid collecting nozzle and the surface to be cleaned; when the scraper scrapes the surface to be cleaned from bottom to top, there is an angle between the extension direction of the scraper and the horizontal direction, so that the liquid collecting port is located below at least one end of the scraper, thereby enabling the scraper to guide the liquid on the surface to be cleaned into the liquid collecting port.

[0011] Beneficial effects: The design of the liquid collecting nozzle makes liquid collection more targeted. Its inlet has an expansion port that forms a liquid collecting port. In conjunction with the scraper, it can accurately gather the liquid guided by the scraper and quickly flow into the liquid collecting structure through the outlet of the liquid collecting nozzle, which greatly improves the liquid collection efficiency and avoids the problem of difficulty in collecting due to liquid dispersion.

[0012] Furthermore, the scraper is equipped with a guide structure; when the scraper scrapes the surface to be cleaned from bottom to top, the guide structure can guide the liquid on the surface to be cleaned into the collection port.

[0013] Beneficial effects: The guiding structure provides a clearer flow path for the liquid, and can more effectively and quickly gather and guide the liquid on the surface to be cleaned to the collection port.

[0014] Furthermore, the liquid collection port is located at the first end of the scraper, and the guide structure is located at the first end of the scraper, extending to the liquid collection port. When the scraper scrapes the surface to be cleaned from bottom to top, the first end of the scraper is inclined downward relative to the second end, so that the liquid on the surface to be cleaned can flow along the scraper to the guide structure, and then be guided to the liquid collection port through the guide structure.

[0015] Beneficial effects: The guide structure is tightly integrated with the scraper and liquid collection port, resulting in a compact overall structure. While ensuring functionality, it reduces additional components, thereby lowering the complexity of the device and the risk of failure. Furthermore, during the cleaning process, the components work together to reduce friction and wear, extend the service life of the cleaning device, and enhance product stability and reliability.

[0016] Furthermore, the guiding structure includes a guide slope, which is disposed at the first end of the scraper; and the guide slope is inclined towards the liquid collection port.

[0017] Beneficial effects: The guide slope is inclined from the first end of the scraper towards the liquid collection port, making full use of the gravity characteristics of the liquid. When the scraper scrapes the surface to be cleaned, the liquid collected can slide down smoothly under the action of gravity. Without the need for additional external force, it can flow into the liquid collection port quickly and smoothly, significantly improving the liquid collection efficiency and reducing liquid residue during the cleaning process.

[0018] Furthermore, the number of scraper strips is set to at least one;

[0019] When the number of scraper blades is set to two or more, there is an angle between the extension directions of two adjacent scraper blades; the liquid collection port is set between two adjacent scraper blades; or, each scraper blade is provided with a corresponding liquid collection port.

[0020] Beneficial effects: When the number of squeegees is set to at least one, multiple squeegees can work simultaneously, increasing the cleaning coverage area and improving cleaning efficiency. Furthermore, when there are two or more squeegees extending at an angle, they can guide liquid from different angles, adapting to various cleaning surfaces. Compared to a single squeegee, it can more effectively collect liquid from the surface to be cleaned, whether it's large areas of liquid or scattered stains, better converging them at the collection port and improving liquid collection efficiency.

[0021] Furthermore, the cleaning device also includes a cleaning rod connected to a cleaning head; a scraper extends along the mounting edge of the cleaning head, the extension direction of the mounting edge being inclined relative to the extension direction of the cleaning rod; or, the extension direction of the mounting edge is perpendicular to the extension direction of the cleaning rod, and there is an angle between the extension direction of the scraper and the extension direction of the mounting edge.

[0022] Beneficial effects: It ensures that when the squeegee is scraping the surface to be cleaned from bottom to top, there is an angle between the extension direction of the squeegee and the horizontal direction; thus, it can effectively collect the liquid on the surface to be cleaned.

[0023] Furthermore, the cleaning head is equipped with a flow guide channel, one end of which is connected to the liquid collection port and the other end is connected to the liquid collection structure.

[0024] Beneficial effects: Liquid can be quickly transferred to the liquid collection structure through the guide channel, avoiding the situation where the cleaning effect of the scraper is affected by the accumulation of liquid.

[0025] Furthermore, the cleaning head has a hollow structure inside, and the flow channel is set inside the hollow structure;

[0026] And / or, the flow channel includes a flow guide tube disposed on the cleaning head, with one end of the flow guide tube connected to the liquid collection port and the other end connected to the liquid collection structure.

[0027] Beneficial effects: The flow channel is set in the hollow structure, which not only makes full use of the internal space of the cleaning head, but also the outer shell of the cleaning head can provide good protection for the flow channel, preventing external collisions from damaging the flow channel and improving the service life of the product.

[0028] Furthermore, the liquid collection structure includes a liquid collection chamber; the liquid collection chamber is disposed on the cleaning head;

[0029] And / or, the cleaning device also includes a cleaning rod connected to the cleaning head, and a liquid collection chamber disposed on or inside the cleaning rod;

[0030] And / or, the collection chamber is located inside an external container;

[0031] And / or, the cleaning head is provided with a wiping section, which forms a liquid collection structure.

[0032] Beneficial effects: It can effectively recycle, store, and reuse liquids on the surface to be cleaned, further improving the ease of use of the product, saving resources, and reducing usage costs.

[0033] Furthermore, the cleaning device also includes a liquid storage structure, which has a liquid storage chamber; the liquid storage structure is provided with a liquid outlet, which is used to guide the liquid in the liquid storage chamber to flow out to the surface to be cleaned and / or the cleaning head;

[0034] When the liquid collection structure includes a liquid collection cavity, the liquid storage cavity forms the liquid collection cavity, and the liquid outlet is located in the liquid collection cavity;

[0035] Alternatively, the liquid collecting chamber is located on the liquid storage structure, and the liquid collecting chamber and the liquid storage chamber are separated from each other. The liquid collecting chamber has a drain port for draining the liquid in the liquid collecting chamber; and / or, the liquid storage chamber and the liquid collecting chamber are connected through a filter channel, and the liquid in the liquid collecting chamber can enter the liquid storage chamber after being filtered through the filter channel.

[0036] And / or, the liquid storage chamber has a liquid inlet for adding liquid into the liquid storage chamber;

[0037] And / or, a nozzle is provided at the liquid outlet; the nozzle is used to spray the liquid in the liquid storage chamber so that the liquid in the liquid storage chamber can be sprayed onto the surface to be cleaned and / or the cleaning head.

[0038] Beneficial effects: It allows for the recycling and reuse of liquids on surfaces to be cleaned, saving resources and reducing costs.

[0039] This cleaning device allows liquid on the surface to be cleaned to flow along the scraper into the collection port under the influence of gravity during the cleaning process, thus collecting the liquid within the collection structure. Furthermore, when the cleaning structure cleans from bottom to top, the scraper guides the liquid on the surface into the collection port; at this time, the scraper is in contact with the surface to be cleaned, preventing the liquid on the surface from flowing to the underside of the scraper under the influence of gravity, which would affect the collection effect. This cleaning device effectively collects liquid generated during the cleaning process. Attached Figure Description

[0050] Furthermore, the technical features involved in the different embodiments of this utility model described below can be combined with each other as long as they do not conflict with each other.

[0051] The following is combined Figures 1-4 The following describes embodiments of the present invention.

[0052] According to an embodiment of this utility model, a cleaning device is provided, including a liquid collection structure 1 and a cleaning head 2. The cleaning head 2 is provided with a guide member and a liquid collection port 41. When cleaning a surface to be cleaned, the guide member of the cleaning head 2 forms an angle with the horizontal direction to guide the liquid on the surface to be cleaned into the liquid collection port 41. Under the action of gravity, the guide structure can smoothly guide the liquid on the surface to be cleaned into the liquid collection port 41, improving the liquid collection efficiency. In this application, the surface to be cleaned can be a glass surface, a floor, a tabletop, etc. In this application, the liquid can be water, a cleaning liquid containing detergent, wastewater that has been used to clean the surface, or any other liquid.

[0053] Furthermore, the surface to be cleaned has an angle with the horizontal direction, meaning the surface to be cleaned can be a vertical surface or an inclined surface; the surface to be cleaned can include a curved surface or a plane.

[0054] According to an embodiment of the present invention, a cleaning device is provided, including a liquid collection structure 1 and a cleaning head 2; the cleaning head 2 is provided with a guide and a liquid collection port 41, and when the cleaning head 2 cleans the surface to be cleaned from bottom to top, the guide direction of the guide has an angle with the horizontal direction; so as to guide the liquid on the surface to be cleaned into the liquid collection port 41.

[0055] In some embodiments, the guide includes a scraper 3, which has an angle between its extension direction and the horizontal direction when scraping the surface to be cleaned, so as to guide the liquid on the surface to be cleaned into the collection port 41.

[0056] In some embodiments, the guide member is a guide channel provided on the cleaning head 2. When the cleaning head 2 cleans the surface to be cleaned, the guide direction of the guide member can guide the liquid on the surface to be cleaned into the liquid collection port 41.

[0057] In some embodiments, the cleaning head 2 includes a mounting plate with a wiping structure on its surface and a flow guide on its surface. When the wiping structure wipes the surface to be cleaned, if there is too much liquid on the surface to be cleaned, some of the liquid is absorbed by the wiping structure, and the excess liquid can be guided into the liquid collection port 41 through the flow guide.

[0058] In some embodiments, the mounting plate is a strip structure; the guide extends along the length of the mounting plate, and when the cleaning head 2 cleans the surface to be cleaned, the extension direction of the guide has an angle with the horizontal direction.

[0059] In some embodiments, the cleaning device includes a cleaning rod 6 and a cleaning head 2 connected together. The cleaning head 2 includes a mounting plate, the surface of which is set at an angle to the extending direction of the cleaning rod 6. This angle can be a right angle, an acute angle, or an obtuse angle.

[0060] In some embodiments, the included angle is an obtuse angle or an acute angle.

[0061] According to an embodiment of the present invention, a cleaning device is provided, including a liquid collection structure 1 and a cleaning head 2. The cleaning head 2 is provided with a scraper 3 and a liquid collection port 41. The scraper 3 and the liquid collection port 41 are positioned correspondingly, so that the scraper 3 can guide liquid on the surface to be cleaned into the liquid collection port 41. The liquid collection port 41 is connected to the liquid collection structure 1. When the cleaning head 2 cleans the surface to be cleaned from bottom to top, the extension direction of the scraper 3 forms an angle with the horizontal direction, so that the liquid collection port 41 is located below at least one end of the scraper 3, thereby enabling the scraper 3 to guide liquid on the surface to be cleaned into the liquid collection port 41, and then into the liquid collection structure 1. In this application, the scraper 3 and the liquid collection port 41 are positioned correspondingly, and when the cleaning head 2 cleans from bottom to top, the extension direction of the scraper 3 forms an angle with the horizontal direction, so that the liquid collection port 41 is located below at least one end of the scraper 3. This design allows the liquid on the surface to be cleaned to flow along the scraper 3 into the collection port 41 under the influence of gravity during the cleaning process, so that the liquid is collected in the collection structure 1. The collection structure 1 is simple and effective; and the structure of the cleaning device of this application is relatively simple, mainly consisting of the collection structure 1 and the cleaning head 2 with the scraper 3 and the collection port 41, which is easy to manufacture and maintain, reducing production and operating costs.

[0062] Furthermore, when the cleaning structure of this application cleans from bottom to top, the scraper 3 guides the liquid on the surface to be cleaned into the collection port 41; at this time, the scraper 3 contacts the surface to be cleaned, which can prevent the liquid on the surface to be cleaned from flowing to the lower side of the scraper 3 under the action of gravity, so as to affect the collection effect.

[0063] In some embodiments, the liquid collection port 41 is located between the first and second ends of the scraper 3 along its length, i.e., the liquid collection port 41 is located in the middle of the scraper 3. When the cleaning head 2 cleans the surface to be cleaned from bottom to top, the liquid collection port 41 is located above the first end and below the second end. The liquid collection port 41 can only collect the liquid to be cleaned above it, while the liquid below it will flow onto the surface to be cleaned for the user to wipe with a wiping structure. For example, when the user wipes the surface to be cleaned below the liquid collection port 41 with a cloth or cotton swab, there is no need to re-absorb water from the cloth or cotton swab; wiping can be done directly. In this embodiment, the liquid collection port 41 can be located anywhere below the second end of the scraper 3.

[0064] In some embodiments, the liquid collection port 41 is located at the first end. When the cleaning head 2 cleans the surface to be cleaned from bottom to top, the liquid collection port 41 can collect all the liquid scraped on the scraper 3.

[0065] In some embodiments, the cleaning head 2 is provided with a protruding liquid collecting nozzle 4, which has an inlet and an outlet communicating with the liquid collecting structure 1. The inlet has an expansion port forming a liquid collecting port 41. When the scraper 3 scrapes the surface to be cleaned, there is a gap between the liquid collecting nozzle 4 and the surface. When the scraper 3 scrapes the surface from bottom to top, the extension direction of the scraper 3 forms an angle with the horizontal direction, so that the liquid collecting port 41 is located below at least one end of the scraper 3, thereby allowing the scraper 3 to guide the liquid on the surface to be cleaned into the liquid collecting port 41. The gap between the liquid collecting nozzle 4 and the surface to be cleaned prevents the liquid collecting nozzle 4 from directly contacting the surface during cleaning, thus avoiding damage to the surface caused by friction or collision. Furthermore, the expansion port of the liquid collecting nozzle 4 is designed as a liquid collecting port 41, facilitating liquid inflow and further improving the liquid collection efficiency and effect.

[0066] In this embodiment, the liquid collecting nozzle 4 can be a funnel-shaped structure; the flared opening at the top of the funnel-shaped structure forms a liquid collecting port 41, and the narrow opening at the bottom forms the outlet of the liquid collecting structure 1; this facilitates the collection of liquid on the surface to be cleaned, and the outlet being at the narrow opening saves space and makes the structure more compact. The outlet is connected to the liquid collecting channel; the outlet can be connected to the liquid collecting structure 1 through a liquid guiding pipe, liquid guiding groove, or other liquid guiding structure.

[0067] In this embodiment, the flared end of the liquid collecting nozzle 4 can be integrally formed with the inlet or it can be detachably connected. When the two are detachably connected, the user can disassemble the flared end structure when there is no need to collect the cleaning liquid. The flared end structure can be screwed or press-fitted to the inlet of the liquid collecting nozzle 4.

[0068] This application also discloses some embodiments in which the scraper 3 is provided with a guide structure 31; when the scraper 3 scrapes the surface to be cleaned from bottom to top, the guide structure 31 can guide the liquid on the surface to be cleaned into the collection port 41. The guide structure 31 makes the scraper 3 guide the liquid on the surface to be cleaned more smoothly and accurately, further improving the collection efficiency and collection effect of the liquid on the surface to be cleaned.

[0069] In some embodiments, the guide structure 31 includes a guide groove or guide bar that extends along the length of the scraper 3.

[0070] This application also discloses some embodiments in which a liquid collection port 41 is disposed at the first end of the scraper 3, and a guide structure 31 is disposed at the first end of the scraper 3, extending to the liquid collection port 41. When the scraper 3 scrapes the surface to be cleaned from bottom to top, the first end of the scraper 3 is inclined downward relative to the second end, so that the liquid on the surface to be cleaned can flow along the scraper 3 to the guide structure 31, and then be guided to the liquid collection port 41 by the guide structure 31. The guide structure 31 extends directly from the first end of the scraper 3 to the liquid collection port 41, constructing a complete and closed liquid guiding path, which can effectively guide the liquid on the surface to be cleaned. When the scraper 3 scrapes from bottom to top, the liquid can flow smoothly along the surface of the scraper 3 into the guide structure 31, and then be guided by the guide structure 31 to the liquid collection port 41. The guide structure 31 is only set at the first end, which is simple in structure, convenient in production, and does not affect the scraping function of the scraper 3. While ensuring the scraping function of the scraper 3, it plays an effective role in guiding the liquid. The guide structure 31 may include at least one of a guide groove, a guide channel, a guide bar, etc.

[0071] This application also discloses some embodiments in which the guide structure 31 includes a guide slope disposed at the first end of the scraper 3; and the guide slope is inclined toward the liquid collection port 41. The guide slope disposed at the first end of the scraper 3 and inclined toward the liquid collection port 41 provides a clear flow path for the liquid. Moreover, the structural design of the guide slope is relatively simple, easy to manufacture and install, and reduces production costs.

[0072] In some embodiments, the first end of the scraper 3 has a curved or bent section that bends or bends toward the liquid collection port 41, and its surface forms a guide slope; not only is the guiding effect good, but the guide structure 31 is also strong and not easily damaged, thus improving the service life of the product.

[0073] In some embodiments, the upper surface of the first end of the scraper 3 is an inclined surface, and the first end of the scraper 3 extends to the liquid collection port 41. The inclined surface is inclined to the liquid collection port 41 so as to guide the liquid flowing down along the scraper 3 into the liquid collection port 41.

[0074] This application also discloses some embodiments in which the number of scraper strips 3 is set to at least one.

[0075] In some embodiments, the number of scraper 3 is set to one. When cleaning the surface to be cleaned, the extension direction of the scraper 3 is inclined relative to the horizontal direction, that is, there is an angle between the extension direction of the scraper 3 and the horizontal direction. The liquid collection port 41 is set below the highest point of the scraper 3 to collect the liquid guided by the upper scraper 3.

[0076] When the number of scraper blades 3 is set to two or more, there is an angle between the extension directions of two adjacent scraper blades 3; the liquid collection port 41 is set between two adjacent scraper blades 3; or, each scraper blade 3 is provided with a corresponding liquid collection port 41.

[0077] This application also discloses some embodiments in which the number of scraper blades 3 is set to two, and the extension directions of the two scraper blades 3 form an angle. The liquid collection port 41 is set between the two scraper blades 3. When the cleaning head 2 cleans the surface to be cleaned, the liquid collection port 41 is located at the lower end of the two scraper blades 3, that is, the two scraper blades 3 form a V-shaped structure, and the liquid collection port 41 is set at the tip of the V-shaped structure. At this time, the liquid collection port 41 can collect the liquid guided by the two scraper blades 3 at the same time, and the liquid collection efficiency is high.

[0078] Furthermore, the number of scraper blades 3 can be set to two or more, such as three, four, five, etc. The extensions of two adjacent scraper blades 3 are all at an angle, that is, each scraper blade 3 forms a W or wave-shaped structure; a liquid collection port 41 is provided at the bottom of each wave; each liquid collection port 41 can collect the liquid guided by two adjacent scraper blades 3 at the same time.

[0079] This application also discloses some embodiments in which the number of scraper 3 is set to two, the extension directions of the two scraper 3 are at an angle, and each scraper 3 is provided with a liquid collection port 41 at the bottom. Each liquid collection port 41 collects the liquid guided by the corresponding scraper 3, which can prevent the liquid from overflowing from a single liquid collection port 41 due to excessive liquid on the surface to be cleaned, thus affecting the collection effect.

[0080] This application also discloses some embodiments in which the cleaning device further includes a cleaning rod 6 connected to the cleaning head 2; the scraper 3 extends along the mounting edge of the cleaning head 2, and the extension direction of the mounting edge is inclined relative to the extension direction of the cleaning rod 6; which is more in line with user habits and improves user experience.

[0081] This application also discloses some embodiments in which the extending direction of the mounting edge is perpendicular to the extending direction of the cleaning rod 6, and the extending direction of the scraper 3 forms an angle with the extending direction of the mounting edge. This conforms to user habits and improves the user experience.

[0082] This application also discloses some embodiments in which a flow guiding channel 5 is provided on the cleaning head 2. One end of the flow guiding channel 5 is connected to the liquid collection port 41, and the other end is connected to the liquid collection structure 1. The liquid collected by the liquid collection port 41 is guided into the liquid collection structure 1 through the flow guiding channel 5, which can effectively collect the liquid. The flow guiding channel 5 can be provided on the outer surface of the cleaning head 2, and the flow guiding channel 5 can be a flow guiding groove.

[0083] This application also discloses some embodiments in which the cleaning head 2 has a hollow structure inside, and the flow channel 5 is disposed within the hollow structure. The flow channel 5, disposed within the hollow structure, not only makes full use of the internal space of the cleaning head 2, but also the outer shell of the cleaning head 2 provides good protection for the flow channel 5, preventing damage from external collisions and improving the product's service life. The flow channel 5 can be a flow groove disposed within the hollow structure. The cleaning head 2 can include a mounting plate, which includes a first plate 21 and a second plate 22 that are detachable from each other. A hollow structure is formed between the first plate 21 and the second plate 22, and the flow channel 5 can be disposed between the first plate 21 and the second plate 22. For example, a first flow groove can be formed on the inner surface of the first plate 21, and a second flow groove can be formed on the inner surface of the second plate 22. The first and second flow grooves interlock to form the flow channel 5. This method eliminates the need for an additional flow tube, is low-cost, easy to manufacture, and less prone to damage. In this case, the scraper 3 can be disposed on the edge of the first plate 21, and the wiping structure can be disposed on the outer surface of the second plate 22. Wiping structures can include wiping cloths, cotton balls, and other absorbent wiping structures.

[0084] In some embodiments, a groove is provided on the first plate 21, and the second plate 22 is a cover plate covering the groove, forming a hollow structure inside the groove. A through hole is provided on the first plate 21, and a liquid collecting nozzle 4 is provided on the outer surface of the first plate 21, with the outlet of the liquid collecting nozzle corresponding to the position of the through hole. One end of the guide channel 5 also corresponds to the position of the through hole, so that the liquid collecting nozzle 4 and the guide channel 5 are interconnected. This arrangement does not affect the wiping structure on the outer surface of the second plate 22 for wiping the surface to be cleaned.

[0085] This application also discloses some embodiments in which the flow channel 5 includes a flow guide tube disposed on the cleaning head 2, with one end of the flow guide tube connected to the liquid collection port 41 and the other end connected to the liquid collection structure 1. The flow guide tube is used as the flow channel 5, and the flow guide tube is detachably disposed on the outside or inside the hollow structure of the cleaning head 2; this facilitates maintenance and replacement.

[0086] In some embodiments, a mounting groove or clamping part is provided on the outer surface of the cleaning head 2 to clamp the guide tube on the clamp or install it in the mounting groove.

[0087] In some embodiments, the guide tube is disposed within the hollow structure of the cleaning head 2, for example, between the first plate 21 and the second plate 22, to facilitate disassembly and maintenance.

[0088] This application also discloses some embodiments, in which the liquid collection structure 1 includes a liquid collection chamber; the liquid collection chamber is disposed on the cleaning head 2. The liquid collection container has a liquid collection chamber inside; the liquid collection container can be fixedly or detachably disposed on the cleaning head 2, facilitating the discharge or cleaning of the collected liquid. For example, the liquid collection container is snap-fitted to the cleaning head 2, integrally connected, or fastened by screws.

[0089] This application also discloses some embodiments, in which the cleaning device further includes a cleaning rod 6, which is connected to the cleaning head 2, and a liquid collection chamber is disposed on or inside the cleaning rod 6.

[0090] In some embodiments, the liquid reservoir forms a cleaning rod 6; the liquid reservoir is fixedly or detachably connected to the cleaning head 2. Users can hold the liquid reservoir to clean the surface to be cleaned.
