[0002] In daily work and life, in addition to cleaning the ground, surfaces perpendicular to the ground, such as walls and windows, also need to be cleaned. Taking windows as an example, the commonly used hand-held window cleaning tools usually come with a window cleaning cloth. During use, the window cleaning cloth and the glass need to be sprayed with water to get wet before cleaning can be carried out. During the cleaning process, the sewage on the window will drip onto the ground or the window sill. After cleaning, the window cleaning cloth needs to be washed by hand. The use process is troublesome and inconvenient to operate. The window cleaning cloth needs to be continuously replaced or cleaned, which is time-consuming and laborious. Utility Model Content

[0003] In view of this, in the first aspect of this application, a cleaning device is provided. The cleaning device is used to clean a to-be-cleaned surface perpendicular to the ground. The cleaning device includes a housing, a water squeezing structure and a cleaning roller installed in the housing. The cleaning roller can rotate around its axis. The water squeezing structure, the housing, and the cleaning roller enclose to form a water tank. The water squeezing structure or the housing is provided with a clean water inlet and a sewage outlet communicating with the water tank. The clean water in the clean water tank can be transmitted to the cleaning roller through the clean water inlet. When the cleaning roller abuts against the to-be-cleaned surface and rotates, the clean water can become sewage. The cleaning roller and the water squeezing structure cooperate to squeeze out the sewage in the cleaning roller, so that the sewage is arranged in the water tank. At the same time, the clean water can also wash the cleaning roller and the sewage. The sewage is discharged into the sewage tank through the sewage outlet.

[0004] For the cleaning device provided in the first aspect of this application, through the mutual cooperation of the housing, the water squeezing structure, and the cleaning roller, the clean water in the clean water tank can be sprayed onto the cleaning roller through the clean water inlet of the water squeezing structure, so that the cleaning roller has its own clean water. Subsequently, when the cleaning roller abuts against the to-be-cleaned surface and rotates, the cleaning of the to-be-cleaned surface can be realized. During the cleaning process, the clean water will turn into sewage. Subsequently, the rotating cleaning roller can cooperate with the water squeezing structure to squeeze out the sewage and contaminants adsorbed on the cleaning roller and arrange them in the water tank. At the same time, the continuous clean water can continuously wash the cleaning roller and the sewage, realizing the self-cleaning of the cleaning roller. Finally, it is recovered into the sewage tank through the sewage outlet.

[0005] In summary, the cleaning device provided in this application uses the real-time self-cleaning principle of the cleaning roller to clean the to-be-cleaned surface. During the cleaning process, it is not necessary to spray water on the to-be-cleaned surface in advance, and it is not necessary to wash the cleaning roller by hand after cleaning. While the cleaning roller cleans the to-be-cleaned surface, the clean water washes the cleaning roller, and the sewage is recovered into the sewage tank without dripping onto the ground. It is convenient for users to use, has a good cleaning effect, and will not cause secondary pollution.

[0006] Among them, the water squeezing structure includes an extrusion member and a sealing member installed on the housing. The extrusion member squeezes the cleaning roller, and the sealing member abuts against the cleaning roller. The extrusion member, the sealing member, the housing, and the cleaning roller enclose to form the water tank.

It should be noted that for those of ordinary skill in the art of this technology, without departing from the principle of this application, several improvements and refinements can still be made, and these improvements and refinements are also regarded as the protection scope of this application.

[0029] In view of this, in order to solve the above problems, this application provides a cleaning device. Please refer to Figures 1 - 4 , Figure 1 which is a three - dimensional structural schematic diagram of the cleaning device in an embodiment of this application. Figure 2 is Figure 1 a three - dimensional structural schematic diagram of another perspective of the cleaning device shown in Figure 3 is Figure 1 a three - dimensional cross - sectional schematic diagram of the cleaning device shown in Figure 4 is Figure 1 a cross - sectional schematic diagram of the cleaning device shown in

[0030] The cleaning device 1 provided in this embodiment is used to clean a surface to be cleaned perpendicular to the ground. The cleaning device 1 includes a housing 10, and a water squeezing structure 20 and a cleaning roller 30 installed on the housing 10. The cleaning roller 30 can rotate around its axis. The water squeezing structure 20, the housing 10, and the cleaning roller 30 enclose to form a water tank 100. The water squeezing structure 20 or the housing 10 is provided with a clean water inlet 201 and a sewage outlet 202 communicating with the water tank 100. The clean water in the clean water tank can be transmitted to the cleaning roller 30 through the clean water inlet 201. When the cleaning roller 30 abuts against the surface to be cleaned and rotates, the clean water can become sewage. The cleaning roller 30 and the water squeezing structure 20 cooperate to squeeze out the sewage in the cleaning roller 30, so that the sewage is located in the water tank 100. At the same time, the clean water can also wash the cleaning roller 30 and the sewage, and the sewage is discharged into the sewage tank through the sewage outlet 202.

[0031] The cleaning device 1 provided in this embodiment is mainly used to clean a surface to be cleaned perpendicular to the ground, such as a wall, glass, tile, window, etc. In this embodiment and the following text, only the surface to be cleaned is a window for illustrative purposes. At this time, the cleaning device 1 can also be called a window cleaning device or a cleaning head.

[0032] The cleaning device 1 mainly includes a housing 10, a cleaning roller 30, and a water squeezing structure 20. The housing 10 is mainly used to install components such as the cleaning roller 30 and the water squeezing structure 20, thereby providing a mounting foundation for the components in the cleaning device 1 and protecting each component. And the housing 10 can be subsequently connected to other components such as the fuselage 40 to form a complete machine.

[0033] The cleaning roller 30 is a component for cleaning the surface to be cleaned and is the main component in the cleaning device 1. The cleaning roller 30 can rotate around its axis, that is, the cleaning roller 30 can rotate by itself (such as Figure 4 rotating in the D direction as shown), and during the rotation process, it can adsorb the dirt on the surface to be cleaned, thereby realizing the cleaning of the surface to be cleaned. Optionally, in one embodiment, the cleaning roller 30 itself does not rotate and can be driven to rotate by the user's thrust. In other embodiments, the cleaning roller 30 itself can rotate by itself driven by components such as a motor. When the user presses the cleaning roller 30 against the surface to be cleaned, the cleaning roller 30 can automatically rotate to clean the surface to be cleaned.

[0034] The water squeezing structure 20 is a component that can squeeze the cleaning roller 30 and squeeze the sewage on the cleaning roller 30 out of the cleaning roller 30. Optionally, the water squeezing structure 20 and the housing 10 can be an integral structure or a split structure. In this embodiment, only the integral structure of the water squeezing structure 20 and the housing 10 is used for illustrative description. The water squeezing structure 20, the housing 10, and the cleaning roller 30 can enclose to form a water tank 100. The sewage squeezed out from the cleaning roller 30 can be stored in the water tank 100, and even part of the clean water can be stored in the water tank 100. A clean water inlet 201 and a sewage outlet 202 communicating with the water tank 100 are provided on the water squeezing structure 20 or the housing 10. The clean water inlet 201 is used to allow the clean water in the clean water tank to enter, and the sewage outlet 202 is used to discharge the sewage into the sewage tank. In this embodiment, only the case where the water squeezing structure 20 is provided with the clean water inlet 201 and the sewage outlet 202 communicating with the water tank 100 is used for illustrative description. Optionally, the water squeezing structure 20 is provided on the side of the cleaning roller 30 away from the surface to be cleaned, that is, the water squeezing structure 20 is provided above the cleaning roller 30.

[0035] As can be seen from the related art, when using a hand-held window cleaning tool with a window cleaning cloth, it is necessary to spray water on the window cleaning cloth and the glass to wet them before cleaning. During the cleaning process, the sewage on the window will drip onto the ground or the window sill. After cleaning, the window cleaning cloth needs to be manually washed. The use process is troublesome and not convenient to operate. The window cleaning cloth needs to be constantly replaced or cleaned, which is time-consuming and laborious. Although there are also hand-held window cleaning tools of the vacuum suction type, they are noisy, scrape the window surface with a soft rubber strip, have a large resistance, and the user experience is not good.

[0036] The cleaning device 1 provided by this embodiment can, through the mutual cooperation of the housing 10, the water squeezing structure 20, and the cleaning roller 30, spray the clean water in the clean water tank onto the cleaning roller 30 through the clean water port 201 of the water squeezing structure 20, so that the cleaning roller 30 is self-supplied with clean water. Subsequently, when the cleaning roller 30 abuts against the surface to be cleaned and rotates, the surface to be cleaned can be cleaned. During the cleaning process, the clean water will become sewage. Subsequently, the rotating cleaning roller 30 can cooperate with the water squeezing structure 20 to squeeze out the sewage and stains adsorbed on the cleaning roller 30 into the water tank 100, and at the same time, the continuous clean water can continuously wash the cleaning roller 30 and the sewage, realizing the self-cleaning of the cleaning roller 30. Finally, it is recycled into the sewage tank through the sewage port 202.

[0037] In summary, the cleaning device 1 provided by this embodiment uses the real-time self-cleaning principle of the cleaning roller 30 to clean the surface to be cleaned such as windows. In other words, this embodiment applies the real-time self-cleaning principle of the cleaning roller 30 to window cleaning. During the cleaning process, it is not necessary to spray and moisten the surface to be cleaned first, and it is not necessary to manually wash the cleaning roller 30 after cleaning. While the cleaning roller 30 is cleaning the surface to be cleaned, the clean water washes the cleaning roller 30, and the sewage is collected into the sewage tank without dripping onto the ground. It is convenient for the cleaning user, has a good cleaning effect, and will not cause secondary pollution.

[0038] Please also refer to Figures 4 - 5 , Figure 5 For Figure 4 the partially enlarged cross-sectional schematic view of the cleaning device shown. In this embodiment, the water squeezing structure 20 includes a squeezing member 21 and a sealing member 22 installed on the housing 10. The squeezing member 21 squeezes the cleaning roller 30, and the sealing member 22 abuts against the cleaning roller 30. The squeezing member 21, the sealing member 22, the housing 10, and the cleaning roller 30 enclose to form the water tank 100; when the cleaning roller 30 rotates, the cleaning roller 30 first passes through the sealing member 22 and then through the squeezing member 21, and the squeezing member 21 cooperates with the cleaning roller 30 to squeeze the sewage on the cleaning roller 30 into the water tank 100.

[0039] The water squeezing structure 20 mainly includes a squeezing member 21 and a sealing member 22. Both the squeezing member 21 and the sealing member 22 are installed on the housing 10. The squeezing member 21, the sealing member 22, and the housing 10 can be of an integral structure or a split structure. In this embodiment, only the integral structure of the squeezing member 21, the sealing member 22, and the housing 10 is used for schematic illustration.

[0040] The extrusion member 21 is mainly used to extrude the cleaning roller 30. In other words, the extrusion member 21 not only abuts against the cleaning roller 30, but also presses into the interior of the cleaning roller 30, pressing out certain grooves on the surface of the cleaning roller 30, and the end of the extrusion member 21 is arranged in the grooves. The above can also be understood as an interference fit between the extrusion member 21 and the cleaning roller 30. Only in this way can the extrusion member 21 extrude the cleaning roller 30, so as to squeeze out the sewage on the cleaning roller 30. The cleaning roller 30 is arranged in the water tank 100. The seal 22 can only abut against the cleaning roller 30 or slightly squeeze the cleaning roller 30, so as to play a role in sealing the water tank 100, preventing the clean water or sewage in the water tank 100 from flowing out of the water tank 100. At the same time, it also prevents the seal 22 from squeezing out the sewage on the cleaning roller 30, so that the sewage cannot enter the water tank 100 and flow outside the cleaning device 1.

[0041] Thus, the extrusion member 21, the seal 22, the housing 10, and the cleaning roller 30 can enclose and form the above-mentioned water tank 100. And when the cleaning roller 30 rotates, as Figure 4 shown, when the cleaning roller 30 rotates counterclockwise, the cleaning roller 30 first passes through the seal 22 and then through the extrusion member 21. Although the seal 22 cooperates with the cleaning roller 30 first, the seal 22 only plays a sealing role and will not cooperate with the cleaning roller 30 to squeeze out the sewage on the cleaning roller 30. Only when the extrusion member 21 cooperates with the cleaning roller 30 will the sewage on the cleaning roller 30 be squeezed out. And in accordance with the rotation direction of the cleaning roller 30, the squeezed sewage can be arranged in the water tank 100 and then discharged into the sewage tank through the sewage outlet 202. In summary, through the cooperation of the extrusion member 21 and the seal 22, not only can a closed space of the water tank 100 be formed, but also the sewage on the cleaning roller 30 can be squeezed out into the water tank 100, realizing the self-cleaning of the cleaning roller 30.

[0042] Please also refer to Figures 5 - 6 , Figure 6 which is Figure 3 a three-dimensional cross-sectional schematic diagram of another perspective of the cleaning device shown. In this embodiment, the seal 22 includes a connecting portion 221 and a sealing portion 222. One end of the connecting portion 221 is connected to the housing 10, and the other end of the sealing portion 222 abuts against the cleaning roller 30; the clean water inlet 201 is arranged on the seal 22 or at one end of the seal 22 along the axial direction of the cleaning roller 30, and the sewage outlet 202 is arranged on the seal 22 or at the other end of the seal 22 along the axial direction of the cleaning roller 30.

[0043] The seal 22 mainly includes a connecting portion 221 and a sealing portion 222. The connecting portion 221 is mainly used to connect the sealing portion 222, and the sealing portion 222 is mainly used to abut against the cleaning roller 30 to seal the water tank 100. Optionally, the connecting portion 221 and the sealing portion 222 can be an integral structure or a split structure. In this embodiment, only the case where the connecting portion 221 and the sealing portion 222 are of an integral structure is schematically illustrated. One end of the connecting portion 221 is used to connect to the housing 10, the other end of the connecting portion 221 is used to bend and connect one end of the sealing portion 222, and the other end of the sealing portion 222 is used to abut against the cleaning roller 30.

[0044] Specifically, the water inlet 201 can be arranged at any position of the seal 22. For example, the water inlet 201 can be arranged on the connecting portion 221 and / or the sealing portion 222. In this embodiment, only the case where the water inlet 201 is arranged on the connecting portion 221 is schematically illustrated. Alternatively, in addition to the connecting portion 221 and the sealing portion 222, other components such as sealing glue and other structures are provided at the opposite ends of the seal 22 along the axial direction of the cleaning roller 30, so as to further enclose the water tank 100. At this time, the water inlet 201 can also be arranged at one end of the seal 22 along the axial direction of the cleaning roller 30.

[0045] The sewage outlet 202 can also be arranged at any position of the seal 22. For example, the sewage outlet 202 can be arranged on the connecting portion 221 and / or the sealing portion 222. In this embodiment, only the case where the sewage outlet 202 is arranged on the sealing portion 222 is schematically illustrated. Alternatively, in addition to the connecting portion 221 and the sealing portion 222, other components such as sealing glue and other structures are provided at the opposite ends of the seal 22 along the axial direction of the cleaning roller 30, so as to further enclose the water tank 100. At this time, the sewage outlet 202 can also be arranged at the other end of the seal 22 along the axial direction of the cleaning roller 30.

[0046] In this embodiment, the sealing portion 222 includes a first part 2221 and a second part 2222. One end of the first part 2221 is bent and connected to the other end of the connecting portion 221, the other end of the first part 2221 is bent and connected to one end of the second part 2222, and the other end of the second part 2222 abuts against the cleaning roller 30. The angle between the first part 2221 and the connecting portion 221 is an acute angle, the angle between the first part 2221 and the second part 2222 is an obtuse angle. The first part 2221 and the second part 2222 of the sealing portion 222 form an inverted V-shaped structure. The first part 2221 is used to prevent sewage from overflowing, and the second part 2222 is convenient for the clean water to better flow onto the cleaning roller 30.

[0047] Optionally, along the extending direction of the water tank 100, i.e., along the axial direction of the cleaning roller 30, from both ends of the water tank 100 to the middle of the water tank 100, the size of the first part 2221 gradually increases, and the size of the second part 2222 gradually decreases. In other words, the size of the first part 2221 is the largest in the middle area of the water tank 100, and the size of the second part 2222 is the largest in the areas at both ends of the water tank 100. This facilitates the sewage to enter the first part 2221 from the middle area of the water tank 100, thus better containing the sewage and making the sewage flow towards the sewage outlet 202. At the same time, the clean water outlet 201 located at the edge can better allow the clean water to flow from the second part 2222 with a larger size at the edge to the cleaning roller 30, so that the clean water is adsorbed onto the cleaning roller 30.

[0048] Please refer to again Figure 3 And Figure 6 , in this embodiment, along the axial direction of the cleaning roller 30, the clean water outlet 201 and the sewage outlet 202 are arranged at opposite ends of the water tank 100.

[0049] In this embodiment, the clean water outlet 201 and the sewage outlet 202 are not arranged on the same side. Instead, along the axial direction of the cleaning roller 30, that is, along the length direction of the cleaning roller 30, the clean water outlet 201 and the sewage outlet 202 are arranged at opposite ends of the water tank 100, such that the clean water outlet 201 and the sewage outlet 202 are respectively arranged corresponding to opposite ends of the cleaning roller 30. In other words, one of the clean water outlet 201 and the sewage outlet 202 is located at the left end of the water tank 100, and the other is located at the right end of the water tank 100. Separating the clean water outlet 201 and the sewage outlet 202 can enable part of the clean water to fall back into the water tank 100 while the clean water is sprayed onto the cleaning roller 30 through the clean water outlet 201. At this time, the clean water at one end will flow towards the sewage outlet 202 at the other end. During this process, the clean water will also push the sewage towards the sewage outlet 202 at the other end, so that the sewage can be better discharged from the sewage outlet 202, and the clean water will continuously flush each wall surface in the water tank 100 to achieve the cleaning of the water tank 100.

[0050] Please refer to again Figure 4 , in this embodiment, the housing 10 is arranged around a part of the outer peripheral side of the cleaning roller 30, and the angle by which the housing 10 surrounds the cleaning roller 30 is not greater than 270°.

[0051] When the cleaning device 1 is working, since not all areas of the cleaning roller 30 need to abut against the surface to be cleaned, only some areas abut against the surface to be cleaned. Therefore, in this embodiment, it can be provided only around a part of the outer peripheral side of the cleaning roller 30, so that the remaining outer peripheral side of the cleaning roller 30 is exposed to clean the surface to be cleaned. And in this embodiment, the angle of the housing 10 around the cleaning roller 30 can be no more than 270°, in other words, the housing 10 surrounds less than half of the outer peripheral side of the cleaning roller 30, so that at least more than half of the outer peripheral side of the cleaning roller 30 is exposed, thereby increasing the exposed area of the cleaning roller 30. When the user uses the cleaning device 1 to clean the surface to be cleaned higher than himself and the surface to be cleaned lower than himself, the contact between the cleaning roller 30 and the surface to be cleaned can be maintained, and the contact between the housing 10 and the surface to be cleaned can be avoided.

[0052] Please refer to Figure 7 , Figure 7 is a side view of the cleaning device in an embodiment of the present application. In this embodiment, the number of the cleaning rollers 30 is one or more. When the number of the cleaning rollers 30 is multiple, the multiple cleaning rollers 30 are arranged along the axial direction parallel to the cleaning roller 30, or the axial direction of the cleaning roller 30 is arranged.

[0053] In this embodiment, the number of the cleaning rollers 30 can be one or more. When the number of the cleaning rollers 30 is multiple, in one embodiment, the multiple cleaning rollers 30 can be arranged along the axial direction parallel to the cleaning roller 30. In other words, the multiple cleaning rollers 30 can be arranged left and right. This embodiment only schematically illustrates with one cleaning roller 30. In other embodiments, the multiple cleaning rollers 30 can be arranged in any direction, such as along the axial direction perpendicular to the cleaning roller 30. In other words, the multiple cleaning rollers 30 can be arranged up and down or left and right. At this time, a water squeezing structure 20 can be provided for each cleaning roller 30 to squeeze water. Or the multiple cleaning rollers 30 are arranged arbitrarily along the axial direction intersecting the cleaning roller 30, such as being inclined or staggered, which should be within the protection scope of the present application.

[0054] In this embodiment, the cleaning roller 30 and the housing 10 are of an integral structure or a split structure. In one embodiment, the cleaning roller 30 can be separately removed from the housing 10. At this time, the cleaning roller 30 and the housing 10 are of a split structure, which is convenient for the disassembly and assembly of the cleaning roller 30. The user can separately clean or replace the cleaning roller 30. In another embodiment, the cleaning roller 30 can also not be removable from the housing 10. At this time, the cleaning roller 30 and the housing 10 are of an integral structure, which can reduce the number of components of the cleaning device 1 and facilitate the assembly of the cleaning device 1.

[0055] Please refer to together Figures 8 - 9 , Figure 8Schematic perspective view of a cleaning machine according to an embodiment of the present application. Figure 9 is Figure 8 Schematic cross-sectional view of the cleaning machine shown. This embodiment provides a cleaning machine 2, which includes a body 40, a handle 50, a clean water tank 60, a sewage tank 70, and a cleaning device 1 provided in the above embodiment of the present application. The cleaning device 1 is installed at one end of the body 40, the handle 50 is installed at the other end of the body 40, the clean water tank 60 communicates with the clean water inlet 201, and the sewage tank 70 communicates with the sewage outlet 202.

[0056] The cleaning machine 2 provided in this embodiment is mainly used to clean a to-be-cleaned surface perpendicular to the ground, such as a wall surface, glass, ceramic tile, window, etc. This embodiment and the following text will only take the to-be-cleaned surface as a window for illustrative purposes. At this time, the cleaning machine 2 can also be called a window cleaning machine. The cleaning device 1 and the handle 50 of the cleaning machine 2 are respectively installed at opposite ends of the body 40. The user can hold the handle 50 and place the cleaning device 1 on the window to clean the window.
