Description

Technical Field

[0001] The present application relates to a contact cleaning device. Background Art

[0002] For contact cleaning devices, there are many types, such as rag spraying, rotating brush flushing, etc. Their basic problem is that during the cleaning process, the cleaning surface such as the rag / brush head, etc., cannot be cleaned by the cleaning water while the cleaning operation (cleaning the surface of the object) is being performed, and the cleaning water will not splash everywhere, flow out of the contact cleaning device, and pollute the environment.

[0003] Between water washing and cleaning the working surface and contact cleaning devices that prevent the cleaning water from leaking out, usually only one can be taken into account:

[0004] Either the cleaning water can be used to clean the surface of the object and the cleaning work surface, such as a flushing rotating brush head, the surface of the object and the rag / brush head are washed with water at the same time, but the cleaning water will flow freely onto the surface of the object or flow into the environment, which is not only not environmentally friendly, but also has usage restrictions in places where the cleaning water is not allowed to flow everywhere, such as mopping robots mopping the floor, washing cars in community parking spaces, etc.;

[0005] Either the cleaning surface is only wetted, in which case the water that wets the rag / brush head will not splash or flow everywhere, but the rag / brush head is only wetted and not cleaned by the cleaning water, that is, during the cleaning process, the dirt on the surface of the object will continue to adhere to the surface of the rag / brush head until the cleaning is completed, such as a contact cleaning device of the water-spraying rag type. In this way, after the cleaning surface of the rag or the like is not sufficient to adhere to the dirt, the cleanliness of the surface of the object will decrease, and spots or stains will appear, and the rag needs to be constantly replaced or scrubbed outside the contact cleaning device, which brings inconvenience to actual use.

[0006] This application will solve this problem. Summary of the invention

[0007] The purpose of the present application is to overcome the deficiencies of the above-mentioned prior art and to provide a contact cleaning device, which aims to solve the problem that the contact cleaning device can only take into account one end: scrubbing the surface of the object and the water washing operation surface, and preventing the cleaning water from leaking out, as well as the problem of usage restrictions in places where the cleaning water is not allowed to flow everywhere.

[0008] This application is implemented as follows:

[0009] A contact cleaning device comprises a sealing mechanism and at least one cleaning roller;

[0010] The cleaning roller can rotate around its central axis, and during the rotation process, its outer cylindrical surface passes through the cleaning position and the self-cleaning position in sequence;

[0011] The outer cylindrical surface of the cleaning roller at the cleaning position is used to directly or indirectly scrub the surface of the object;

[0012] The sealing mechanism and the cleaning roller together form a closed self-cleaning chamber in the self-cleaning position, and the outer cylindrical surface of the cleaning roller in the self-cleaning position is a local cleaning roller structural surface of the closed self-cleaning chamber, and the cleaning water in the closed self-cleaning chamber is self-cleaned. When entering and moving out of the self-cleaning position, the outer cylindrical surface of the cleaning roller in the self-cleaning position is squeezed by drainage, and the cleaning water in the closed self-cleaning chamber is prevented from leaking out.

[0013] Among them, the closed form of the closed self-washing chamber involved in the present application is the only way to prevent the cleaning water in the closed self-washing chamber from leaking out of the cleaning device, that is, there is no such shell outside the closed self-washing chamber, which wraps the closed self-washing chamber, the sealing mechanism, and the cleaning roller to prevent or recover the cleaning water leaking out of the closed self-washing chamber.

[0014] During specific use, the cleaning roller rotates and passes through the cleaning position and the self-cleaning position in turn during the rotation process, and the cleaning roller continuously rotates around its central axis, wherein the cleaning roller cleans the surface of the object at the cleaning position, and during this cleaning process, the dirt on the surface of the object will adhere to the outer cylindrical surface of the cleaning roller at the cleaning position, and the dirt attached to the outer cylindrical surface of the cleaning roller will move to the self-cleaning position as the cleaning roller rotates, and when the outer cylindrical surface of the cleaning roller with dirt attached moves to the self-cleaning position, a cleaning agent will be placed in the closed self-cleaning chamber during specific use. Washing water, or circulating cleaning water, the cleaning water in the closed self-cleaning chamber will clean and self-clean the outer cylindrical surface of the cleaning roller with dirt attached, such as scrubbing, pressure washing, ultrasonic decontamination, etc., and the outer cylindrical surface of the cleaning roller in the self-cleaning position is squeezed by the interaction of the sealing mechanism when entering and moving out of the self-cleaning position, wherein the extrusion method is adopted to squeeze out most of the water on the outer cylindrical surface of the cleaning roller, so that the outer cylindrical surface of the cleaning roller basically does not flow out water when being squeezed, so that the outer cylindrical surface of the cleaning roller can be kept moist and does not drip water when it reaches the cleaning position.

[0015] Based on the structural design of the present application, firstly, according to the above-mentioned usage process description, the contact cleaning device can continuously and cyclically use the outer cylindrical surface of the cleaning roller to clean the surface of the object, and during the cleaning operation, the cleaning water will not splash, flow, or leak into the environment. In this way, the problem of only being able to take into account one end at a time between scrubbing the surface of the object and washing the outer cylindrical surface of the cleaning roller with water, and preventing the cleaning water from leaking out of the contact cleaning device is solved. The outer cylindrical surface of the cleaning roller can be continuously washed with water, the outer cylindrical surface of the cleaning roller can be continuously wrung out, and the surface of the object can be continuously cleaned with the clean outer cylindrical surface of the cleaning roller, which can effectively avoid leaving spots or stains on the surface of the object. Secondly, since it is a closed self-cleaning chamber, the surface of the object can be set horizontally and upward, or vertically, or horizontally and downward. The contact cleaning device will not drip or leak in any placement state and can be used normally.

[0016] In specific applications, the present application can use less cleaning water to clean relatively dirty surfaces of objects, which is not only environmentally friendly, but also brings convenience for cleaning work that is not carried out near a water source, such as self-car washing in a parking space; it brings convenience for work that requires large-area cleaning without frequent replacement of rags, such as mopping robots; and it brings convenience for cleaning work in situations where cleaning water is not allowed to flow everywhere, such as cleaning floors, walls, internal and external window glass, etc. BRIEF DESCRIPTION OF THE DRAWINGS

[0033] DETAILED DESCRIPTION

[0034] In order to make the purpose, technical solution and advantages of the present application more clearly understood, the present application is further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present application and are not used to limit the present application.

[0035] The present application provides a contact cleaning device for cleaning the surface of an object.

[0036] Specifically, the contact cleaning device includes a sealing mechanism 100 and at least one cleaning roller 200, wherein the cleaning roller 200 can be a cylinder or a truncated cone; usually, the axial dimension of the cleaning roller 200 is larger than its average radial dimension, which is more effective in cleaning the surface of an object.

[0037] The cleaning roller 200 can rotate around its central axis and sequentially pass through a cleaning position and a self-cleaning position during the rotation process.

[0038] The outer cylindrical surface of the cleaning roller 200 in the cleaning position is used to directly or indirectly abut the surface of an object. Specifically, the outer cylindrical surface of the cleaning roller 200 may be provided with a cleaning material capable of cleaning the surface of an object, such as a rag 600 or bristles. In this case, the cleaning roller 200 directly abuts the surface of the object. The outer cylindrical surface of the cleaning roller 200 may also not be provided with a cleaning material capable of cleaning the surface of an object. During specific use, the cleaning material is connected to the outer cylindrical surface of the cleaning roller 200. In this case, the cleaning material is a consumable part.

[0039] The enclosing mechanism 100 and the cleaning roller 200 form a closed self-cleaning chamber in the self-cleaning position. The outer cylindrical surface of the cleaning roller 200 in the self-cleaning position is a local structural surface of the closed self-cleaning chamber 101. On this structural surface, after passing through the self-cleaning position, it becomes a self-cleaning surface, and the cleaning water in the closed self-cleaning chamber 101 is self-cleaned. When the outer cylindrical surface of the cleaning roller 200 in the self-cleaning position enters and moves out of the self-cleaning position, it is squeezed by drainage, and the cleaning water in the closed self-cleaning chamber 101 is prevented from leaking out. It should be noted that when the outer cylindrical surface of the cleaning roller 200 in the self-cleaning position enters and moves out of the self-cleaning position, it can be squeezed by drainage under the interaction of the enclosing mechanism 100, or it can be squeezed by drainage under the interaction of another cleaning roller 200.

[0040] During specific use, the cleaning roller 200 rotates around its central axis, and passes through the cleaning position and the self-cleaning position in sequence during the rotation, and the cleaning roller 200 continuously rotates around its central axis, wherein the cleaning roller 200 cleans the surface of the object at the cleaning position, and during this cleaning process, the dirt on the surface of the object will adhere to the outer cylindrical surface of the cleaning roller 200 at the cleaning position, and the dirt attached to the outer cylindrical surface of the cleaning roller 200 will move to the self-cleaning position as the cleaning roller 200 rotates, and when the outer cylindrical surface of the cleaning roller 200 with dirt attached moves to the self-cleaning position, since cleaning water is placed in the closed self-cleaning chamber 101 during specific use, or circulating The cleaning water in the closed self-cleaning chamber 101 will clean and self-clean the outer cylindrical surface of the cleaning roller 200 with dirt attached, such as scrubbing, pressure washing, ultrasonic decontamination, etc., and when the outer cylindrical surface of the cleaning roller 200 at the self-cleaning position enters and moves out of the self-cleaning position, it is subjected to drainage squeezing under the interaction of the enclosing mechanism 100 or under the interaction of another cleaning roller 200, wherein the extrusion method can squeeze out most of the water on the outer cylindrical surface of the cleaning roller 200, so that the outer cylindrical surface of the cleaning roller 200 basically does not flow out water when being squeezed, so that the outer cylindrical surface of the cleaning roller 200 can be kept moist and does not drip water when it reaches the cleaning position.

[0041] Based on the structural design of the present application, firstly, according to the above-mentioned usage process description, the contact cleaning device can continuously and cyclically use the outer cylindrical surface of the cleaning roller 200 to clean the surface of the object, and during the cleaning operation, the cleaning water will not splash, flow, or leak into the environment. In this way, the problem of only being able to take into account one end between scrubbing the surface of the object and washing the outer cylindrical surface of the cleaning roller 200 with water, and preventing the cleaning water from leaking out of the contact cleaning device is solved. The outer cylindrical surface of the cleaning roller 200 can be continuously washed with water, the outer cylindrical surface of the cleaning roller 200 can be continuously wrung out, and the surface of the object can be continuously cleaned with the clean outer cylindrical surface of the cleaning roller 200, which can effectively avoid leaving spots or stains on the surface of the object. Secondly, since it is a closed self-cleaning chamber 101, the surface of the object can be set horizontally and upward, or vertically, or horizontally and downward. The contact cleaning device will not drip or leak in any placement state and can be used normally.

[0042] In the specific application process, the present application can use less cleaning water to clean the relatively dirty surface of objects, which is not only environmentally friendly, but also brings convenience for cleaning work that is not carried out near a water source, such as self-car washing in a parking space; it brings convenience for work that is not easy to frequently change the rag 600 but needs to clean a large area, such as a mopping robot; and it brings convenience for cleaning work in situations where cleaning water is not allowed to flow everywhere, such as cleaning floors, walls, internal and external window glass, etc.

[0043] It should be noted that, in a specific embodiment, a sealing structure is provided at the joint between the enclosing mechanism 100 and the cleaning roller 200 to achieve a sealed connection, wherein the method for achieving the seal can be selected according to the specific structural shape of the joint; the surface of the object can be a flat surface or a profiled surface.

[0044] The following examples illustrate possible implementations:

[0045] Embodiment 1

[0046] See also Figure 1 In this embodiment, based on the aforementioned structure, a cleaning roller 200 is provided.

[0047] In this embodiment, the enclosure mechanism 100 includes an enclosure structure 110 , and the enclosure structure 110 includes an enclosure component 111 and two baffles 112 ; the enclosure component 111 and the cleaning roller 200 are both located between the two baffles 112 .

[0048] It should be noted that in the above-mentioned indirect scrubbing situation, the rag 600 can be attached to the outer cylindrical surface of the cleaning roller 200, see Figure 2 , Figure 3 , respectively showing the closing and locking methods of two types of rags 600 at both ends of the cleaning roller 200.

[0049] Among them, when the two ends of the cleaning roller 200 use a one-piece seal 310, as shown in the figure, the rag 600 wrapped and attached to the outer cylindrical surface of the cleaning roller 200 can be closed at both ends of the cleaning roller 200 by means of the depressions set at both ends of the cleaning roller 200 and the matching plugging covers 330, so that the two ends of the rag 600 are locked on the cleaning roller 200, so that the rag 600 wrapped and attached to the end face of the one-piece seal 310 and the end face of the one-piece seal 310 can jointly participate in the sealing between the baffle 112; similarly, when the thickness of the rag 600 is appropriate and the one-piece seal 310 is soft enough, the rag 600 clamped between the baffle 112 and the end face of the one-piece seal 310 can participate in the sealing without leaking.

[0050] When the two ends of the cleaning roller 200 use split seals 320, Figure 3As shown, the rag 600 wrapped and attached to the outer cylindrical surface of the cleaning roller 200 can pass through the hole in the annular split seal 320, appropriately tighten the two ends of the rag 600, and use the annular split seal as the interface along the two end cylindrical surfaces of the cleaning roller 200 to press and close the ends, so that the rag 600 is wrapped and attached to the outer cylindrical surface of the cleaning roller 200 smoothly without wrinkles. At the same time, after being pressed and fitted by the annular split seal, the excess rag 600 at the two ends of the cleaning roller 200 is cut off to serve as the closing ends of the cleaning roller 200, that is, the annular split seal 320 at this time also assumes the work of the closing lock of the rag 600 (the two end surfaces of the cleaning roller 200 are not in direct contact with the baffle 112, therefore, a small amount of excess rag 600 ends are left on the two end surfaces, which does not affect the sealing).

[0051] When the cleaning belt 1111 is used as a flexible member to wrap around the outer cylindrical surface of the cleaning roller 200, the rag 600 can be attached to the outer cylindrical surface of the cleaning belt 1111. Specifically, as shown in FIG. Figure 4 As shown in FIG. 6A , when the rag 600 is thin enough, the rags 600 can partially overlap each other without affecting the tight fit and sealing between the cleaning rollers 200 and the sealing mechanism 100. Figure 4 The rag 600 shown in FIG. 1B just surrounds the cleaning roller 200 for one cycle. Figure 4 As shown in C, the rag 600 just surrounds the cleaning roller 200 for one circle, and both ends of the rag 600 are embedded in the cleaning roller 200 and are pressed and locked.

[0052] Embodiment 2

[0053] See also Figure 5 This embodiment is similar to the first embodiment (structure as Figure 1 The difference between the above-mentioned cleaning rollers 200 and the above-mentioned cleaning rollers 200 is that at least two cleaning rollers 200 are provided, and the cleaning rollers 200 are arranged in sequence, wherein an enclosed gap is left between at least two adjacent cleaning rollers 200; the enclosing mechanism 100 includes an enclosing structure 110 (only a part of the figure is shown) and at least one enclosed roller 120, and the central axis of the enclosed roller 120 is parallel to the central axis of the cleaning roller 200; at least one enclosed roller 120 is provided in the enclosed gap, wherein, as shown in FIG. Figure 5 As shown, the enclosed gap may be provided with only one enclosed roller 120, or may be provided with two or more enclosed rollers 120; the enclosing mechanism 100, each enclosed roller 120 and each cleaning roller 200 together form a closed self-cleaning chamber 101. Based on this, by increasing the number of cleaning rollers 200, the cleaning capacity of the contact cleaning device per unit time can be enhanced.

[0054] In this embodiment, two cleaning rollers 200 are provided and one enclosing roller 120 is provided.

[0055] In other embodiments, there may be no spacing between the two cleaning rollers 200, that is, they are in direct contact. Specifically, at least two cleaning rollers 200 are provided, and each cleaning roller 200 is arranged in sequence, wherein at least two adjacent cleaning rollers 200 are in contact with each other. Increasing the number of cleaning rollers 200 can enhance the cleaning capacity of the contact cleaning device per unit time.

[0056] It should be noted here that, in the process of the outer cylindrical surface of the cleaning roller 200 in the self-cleaning position passing through the self-cleaning position, at least one of the side surfaces between the outer cylindrical surface of the cleaning roller 200 in the self-cleaning position and the extrusion surface that squeezes the outer surface of the cleaning roller 200 is made of a flexible material, that is, between the two cleaning rollers 200, between the cleaning roller 200 and the enclosing roller 120, and between the cleaning roller 200 and the enclosing mechanism 100, in the two tightly pressed fitting surfaces, at least one side surface is made of a flexible material, including a rag 600 attached to the outer cylindrical surface of the cleaning roller 200, wherein the typical matching relationship between the two cleaning rollers 200 and between the cleaning roller 200 and the enclosing roller 120 in the use state is as follows Figure 6 As shown, the enclosing roller 120 (cleaning roller 200) is tightly attached to the cleaning roller 200, and the outer cylindrical surface of the cleaning roller 200 is squeezed by the enclosing roller 120, which will produce a certain deformation. The contact between the cleaning roller 200 and the enclosing roller 120 is surface contact. This contact surface plays an important sealing role. It can avoid water leakage due to jumping between the cleaning roller 200 and the enclosing roller 120 due to rigid contact between the two or shaking during the use of the contact cleaning device; further, between the two cleaning rollers 200, between the cleaning roller 200 and the enclosing roller 120, and between the cleaning roller 200 and the sealing mechanism 100 (such as the above-mentioned embodiment 1), at least one side of the outer surfaces that are tightly pressed together are a flexible surface.

[0057] Embodiment 3

[0058] This embodiment is similar to the second embodiment (structure as Figure 5 The difference between the embodiment shown in the figure is that at least two adjacent cleaning rollers 200 are in contact with each other, that is, in this embodiment, a part of two adjacent cleaning rollers 200 are in direct contact with each other, and a part of two adjacent cleaning rollers 200 are not in direct contact with each other, but a gap is left between them.

[0059] Embodiment 4

[0060] See also Figure 7 This embodiment is similar to the second embodiment (structure as Figure 5 The difference from the embodiment shown in FIG. 1 is that two enclosing rollers 120 are provided.

[0061] Embodiment 5

[0062] See also Figure 8 and Fig.10 In this embodiment and the second embodiment (structure as Figure 5 The difference between the above-mentioned embodiment and the above-mentioned embodiment is that there are three enclosing rollers 120; the enclosing structure 110 includes an enclosing member 111 and two baffles 112; the enclosing member 111 and the cleaning roller 200 are both located between the two baffles 112; the enclosing member 111, the cleaning roller 200 and the two baffles 112 together enclose a closed self-cleaning chamber 101. The structure is simple, stable, reliable and easy to implement. In a specific embodiment, it is only necessary to achieve sealing at the joints between the enclosing member 111, the cleaning roller 200 and the two baffles 112. The sealing method can be selected according to the specific structural shape of the joint using conventional technical means in the art.

[0063] See also Figure 8 , its structure shows one of the sealing forms, and sealing members are provided at both ends of the cleaning roller 200 and the enclosing roller 120. According to actual needs, they can be divided into a one-piece sealing member 310 connected to the outer cylindrical surface of the cleaning roller 200 and the enclosing roller 120 and a separate one-piece sealing member 320 (in this embodiment, as shown in the figure, one end of the two ends of the cleaning roller 200 and the enclosing roller 120 is provided with a one-piece sealing member 310, and the other end is provided with a separate one-piece sealing member 320; in other embodiments, both ends of the cleaning roller 200 and the enclosing roller 120 may be provided with a one-piece sealing member 310. The one-piece seal 310 or the split seal 320 may also be provided, the shaded portion on the baffle 112 is a smooth (table) surface, which is pressed and contacted with the one-piece seal 310 or the split seal 320 to achieve sealing. When cleaning water is placed in the closed self-cleaning chamber 101, the seal and the smooth surface can both slide and seal, and the rotation and sealing of the cleaning roller 200 and the enclosing roller 120 can be achieved. Conversely, the smooth surface can be set at both ends of the cleaning roller 200 and the enclosing roller 120, and the seal can be set at the shaded portion of the baffle 112, and sealing can be achieved in the same way. Among them, the smooth surface is a raised table surface, which is only arranged in the fan-shaped area enclosed by the closed self-cleaning chamber 101. In this way, in each round of rotation, the seals at both ends of the cleaning roller 200 or the enclosing roller 120 only need to participate in the sealing when constructing the closed self-cleaning chamber 101 and are in the fan-shaped area enclosed by the closed self-cleaning chamber 101. After leaving the fan-shaped area enclosed by the closed self-cleaning chamber 101, the seal is disengaged from the smooth surface. This arrangement not only improves the service life of the seal, but also effectively reduces the rotation resistance of the cleaning roller 200 or the enclosed roller 120.

[0064] See also Fig. 9The outer cylindrical surface of the cleaning roller 200 in the self-cleaning position is the cleaning roller structural surface 201 of the closed self-cleaning cavity 101, and the outer cylindrical surface of the enclosing roller 120 is the enclosing roller structural surface 121 of the closed self-cleaning cavity 101, which together participate in constructing the closed self-cleaning cavity 101. Among them, the dotted frame area on the cleaning roller structural surface 201 can be set as the self-cleaning area of ​​the outer cylindrical surface of the cleaning roller 200 in the closed self-cleaning cavity 101.

[0065] See also Figure 8 , Fig.10 and Fig.11 In this embodiment, the enclosure mechanism is provided with a pressing adjustment mechanism 500, which is used to adjust the squeezing force on the outer cylindrical surface of the cleaning roller 200 in the self-cleaning position when it moves out of the closed self-cleaning chamber 101. In this way, the squeezing force on the outer cylindrical surface of the enclosing roller 120 when the outer cylindrical surface of the cleaning roller 200 in the self-cleaning position enters and moves out of the self-cleaning position can be adjusted and controlled.

[0066] Specifically, two cleaning rollers 200 are provided, and the column end of the cleaning roller 200 has a bearing 590. The clamping adjustment mechanism 500 includes a first radial locking ring 510, a second radial locking ring 520, a first clamping force spring 530, a second clamping force spring 540, a clamping force wrench 550 and a clamping force adjustment bolt 560; the first radial locking ring 510 and the first clamping force spring 530 are locked and connected by rotating 90 degrees by the first locking buckle 581, and then rotated 90 degrees by the first locking buckle 581 to unlock and disengage, so that the first radial locking ring 510 is disengaged from the bearing 590 of the corresponding cleaning roller 200, so as to load or remove the corresponding cleaning roller 200, such as Fig.10 Similarly, the second radial locking ring 520 and the second pressing force spring 540 are locked and connected by rotating the second locking buckle 582 by 90 degrees, and then unlocked and disengaged by rotating the second locking buckle 582 by 90 degrees, so that the second radial locking ring 520 is disengaged from the bearing 590 of the corresponding cleaning roller 200, so as to install or remove the corresponding cleaning roller 200;

[0067] One end of the first radial locking ring 510 is hinged on the baffle 112, and the rotation axis is parallel to the central axis of the cleaning roller 200. The middle of the first radial locking ring 510 presses the corresponding bearing 590 of the cleaning roller 200. The other end of the first radial locking ring 510 and one end of one of the first pressing force springs 530 are connected or disconnected by rotating the first lock buckle 581 90 degrees.

[0068] One end of the second radial locking ring 520 is hinged on the baffle 112, and the rotation axis is parallel to the central axis of the cleaning roller 200. The middle of the second radial locking ring 520 presses the bearing 590 of the cleaning roller 200 on the other side. The other end of the second radial locking ring 520 and one end of another second pressing force spring 540 are connected or disconnected by rotating the second lock buckle 582 90 degrees.

[0069] The other end of the first clamping force spring 530 is connected to the clamping force wrench 550;

[0070] The other end of the second clamping force spring 540 is connected to the clamping force wrench 550;

[0071] The clamping force wrench 550 is threadedly connected to the clamping force adjusting bolt 560 , wherein the distance between the clamping force wrench 550 and the first radial locking ring 510 and the distance between the clamping force wrench 550 and the second radial locking ring 520 can be adjusted by rotating the clamping force adjusting bolt 560 .

[0072] The lower end of the clamping force adjusting bolt 560 is connected to the steering member 570. When the clamping force adjusting bolt 560 rotates, the clamping force wrench 550 can be raised or lowered, thereby adjusting the distance between the clamping force wrench 550 and the first radial locking ring 510 and adjusting the distance between the clamping force wrench 550 and the second radial locking ring 520.

[0073] The clamping force wrench 550 is hinged on the baffle 112 through the clamping force adjusting bolt 560 and the steering member 570, and its upper end can be turned outward away from the baffle 112; when the upper end of the clamping force wrench 550 is vertically pressed inwardly against the baffle 112, the first clamping force spring 530 and the second clamping force spring 540 are in a long-distance state, and the spring force lifts the first radial locking ring 510 and the second radial locking ring upward, so that the bearings 590 of the two cleaning rollers 200 are squeezed toward the rollers 120 on both sides thereof, so that the cleaning rollers 200 are pressed against the rollers 120 on both sides. The roller 200 is pressed tightly against the enclosing roller 120; when the upper end of the clamping force wrench 550 is pulled outward away from the baffle 112 and tilted outward, the first clamping force spring 530 and the second clamping force spring 540 are in a short-distance state and relaxed, and the first locking buckle 581 and the second locking buckle 582 can be rotated 90 degrees, so that the first clamping force spring 530 and the second clamping force spring 540 are disengaged from the first radial locking ring 510 and the second radial locking ring 520, and the cleaning roller 200 can be installed or removed respectively.

[0074] At the same time, from Fig.10It can be seen that the cleaning roller 200 is easy to be loaded and taken out, and it is easy to be pressed and sealed with the enclosing roller 112 after loading to construct a closed self-cleaning chamber 101; and, after taking out, it is easy to replace the split seal 320 and the rag 600 (if any), and leave a gap that penetrates up and down at the loading position of the cleaning roller 200, that is, between the two enclosing rollers 112, so that it is easy to wash away the dirt remaining inside the contact cleaning device.

[0075] In specific use, the distance between the clamping force wrench 550 and the first radial locking ring 510 and the distance between the clamping force wrench 550 and the second radial locking ring 520 can be adjusted by rotating the clamping force adjusting bolt 560, thereby changing the spring force of the first clamping force spring 530 and the second clamping force spring 540, and adjusting the clamping force between the first radial locking ring 510 and the second radial locking ring 520 and the enclosing roller 120. In this way, such a clamping force can always be found between the cleaning roller 200 and the enclosing roller 120, so that the clamping and squeezing surface can wring out the moisture on the cleaning roller 200, or wring out the moisture of the rag 600 on the cleaning roller 200, so that it is moist and does not drip.

[0076] Similarly, through reasonable transformation, the clamping adjustment mechanism 500 is applicable to other embodiments of the present application, including embodiment one.
