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 water, rotating brush flushing, etc. Their basic problem is that during the cleaning process, the rag / brush head cannot be cleaned by the cleaning water while cleaning the surface of the object, and the cleaning water will not splash everywhere, flow out of the contact cleaning device, and pollute the environment.

[0003] Between scrubbing the surface of the object and washing the working surface with water, and contact cleaning devices that do not leak the cleaning water, usually only one side can be taken into account:

[0004] Alternatively, the surface of the object and the working surface can be cleaned with cleaning water, such as a flushing rotating brush head, but the cleaning water will flow freely onto the surface of the object or 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 working 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 rag is not enough 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 an annular cleaning belt;

[0010] The cleaning winding belt can be moved along its looped path and pass through the cleaning position and the self-cleaning position in sequence during the moving process;

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

[0012] The sealing mechanism and the cleaning belt together form a closed self-cleaning chamber in the self-cleaning position, and the outer ring belt surface of the belt segment of the cleaning belt in the self-cleaning position is a local 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 ring belt surface of the belt segment of the cleaning belt in the self-cleaning position is squeezed by drainage due to the interaction of the sealing mechanism, 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 belt to prevent or recover the cleaning water leaking from the closed self-washing chamber.

[0014] During specific use, the cleaning belt moves along its looped path, and passes through the cleaning position and the self-cleaning position in sequence during the movement, and the cleaning belt continuously circulates along its looped path, wherein the cleaning belt 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 ring belt surface of the belt section of the cleaning belt at the cleaning position, and the dirt attached to the outer ring belt surface of the cleaning belt will move to the self-cleaning position as the cleaning belt moves, and when the outer ring belt surface of the cleaning belt with dirt attached moves to the self-cleaning position, due to the specific use process, in the closed self-cleaning chamber By placing cleaning water or circulating cleaning water, the cleaning water in the closed self-cleaning chamber will clean and self-clean the outer ring belt surface of the cleaning belt with dirt attached, such as scrubbing, pressure flushing, ultrasonic decontamination, etc., and the outer ring belt surface of the cleaning belt at the self-cleaning position is squeezed by the sealing mechanism when entering and moving out of the self-cleaning position. Among them, the squeezing method can squeeze out most of the water on the outer ring belt surface of the cleaning belt, and at the same time, the outer ring belt surface of the cleaning belt can basically not flow out water when it is squeezed. In this way, the outer ring belt surface of the cleaning belt 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 ring belt surface of the cleaning belt to clean the surface of the object, and the cleaning water will not splash or flow during the cleaning process, and will not 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 ring belt surface of the cleaning belt with water, and preventing the cleaning water from leaking out of the contact cleaning device is solved. The outer ring belt surface of the cleaning belt can be continuously washed with water, the outer ring belt surface of the cleaning belt can be continuously wrung out, and the surface of the object can be continuously cleaned with the clean outer ring belt surface of the cleaning belt, which can effectively avoid leaving spots or stains on the surface of the object. Secondly, since the closed self-cleaning chamber is closed, 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

[0032] DETAILED DESCRIPTION

[0033] 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.

[0034] The present application provides a contact cleaning device for cleaning the surface of an object.

[0035] Specifically, the contact cleaning device includes a sealing mechanism 100 and a ring-shaped cleaning belt 200, wherein the ring shape can be a circular ring, an elliptical ring, a special-shaped ring, and the like.

[0036] The enclosing mechanism 100 enables the cleaning winding belt 200 to travel along its looped path and pass through the cleaning position and the self-cleaning position in sequence during the traveling process.

[0037] The outer ring belt surface of the belt section of the cleaning belt 200 in the cleaning position is used to directly or indirectly abut the surface of the object. Specifically, the outer ring belt surface of the cleaning belt 200 may be provided with cleaning materials capable of cleaning the surface of the object, such as a rag or bristles. At this time, the cleaning belt 200 directly abuts the surface of the object. The outer ring belt surface of the cleaning belt 200 may also be provided without cleaning materials capable of cleaning the surface of the object. The cleaning materials are connected to the outer ring belt surface of the cleaning belt 200 during specific use. At this time, the cleaning materials are consumables.

[0038] The enclosing mechanism 100 and the cleaning belt 200 form a closed self-cleaning chamber 101 in the self-cleaning position. The outer ring belt surface of the belt segment of the cleaning belt 200 in the self-cleaning position is a local structural surface of the closed self-cleaning chamber 101. In addition, 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 entering and moving out of the self-cleaning position, the outer ring belt surface of the belt segment of the cleaning belt 200 in the self-cleaning position 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 the outer cylindrical surface of the cleaning belt 200 in the self-cleaning position can be squeezed by drainage under the interaction of the enclosing mechanism 100 when entering and moving out of the self-cleaning position, or it can be squeezed by drainage under the interaction of another cleaning belt 200.

[0039] During specific use, the cleaning belt 200 travels along its loop path, and passes through the cleaning position and the self-cleaning position in sequence during the traveling process, and the cleaning belt 200 continuously circulates along its loop path, wherein the cleaning belt 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 ring belt surface of the belt section of the cleaning belt 200 at the cleaning position, and the dirt attached to the outer ring belt surface of the cleaning belt 200 will move to the self-cleaning position as the cleaning belt 200 travels, and when the outer ring belt surface of the cleaning belt 200 with dirt attached moves to the self-cleaning position, since during specific use, cleaning water will be placed in the closed self-cleaning chamber 101, or The cleaning water is circulated, and the cleaning water in the closed self-cleaning chamber 101 will clean and self-clean the outer ring belt surface of the cleaning belt 200 with dirt attached, such as scrubbing, pressure flushing, ultrasonic decontamination, etc., so that the outer ring belt surface of the cleaning belt 200 at the self-cleaning position is subjected to drainage squeezing under the action of the enclosing mechanism 100 or under the interaction with another cleaning belt 200 when entering and moving out of the self-cleaning position. Among them, the extrusion method can squeeze out most of the water on the outer ring belt surface of the cleaning belt 200, and at the same time, the outer ring belt surface of the cleaning belt 200 basically does not flow out water when it is squeezed. In this way, the outer ring belt surface of the cleaning belt 200 can be kept moist and does not drip water when it reaches the cleaning position.

[0040] 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 ring belt surface of the cleaning belt 200 to clean the surface of the object, and the cleaning water will not splash or flow during the cleaning process, and will not 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 ring belt surface of the cleaning belt with water, and preventing the cleaning water from leaking out of the contact cleaning device is solved. The outer ring belt surface of the cleaning belt 200 can be continuously washed with water, the outer ring belt surface of the cleaning belt 200 can be continuously wrung out, and the surface of the object can be continuously cleaned with the clean outer ring belt surface of the cleaning belt 200, which can effectively avoid leaving spots or stains on the surface of the object. Secondly, since the closed self-cleaning chamber 101 is closed, 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.

[0041] 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.

[0042] 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 belt 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.

[0043] The following examples illustrate possible implementations:

[0044] Embodiment 1

[0045] See also Figure 1 The contact cleaning device further comprises at least two built-in rollers 320, the outer cylindrical surfaces of each built-in roller 320 abut against the inner annular surface of the cleaning belt 200, and the central axes of each built-in roller 320 are parallel to each other. Based on this, the outer annular surface of the belt section of the cleaning belt 200 in the cleaning position can be made flat, and the size of the outer annular surface of the belt section of the cleaning belt 200 in the cleaning position can be set according to actual use requirements. In this way, when the surface of the object is flat, it can be helpful to increase the area of ​​the cleaning working surface.

[0046] Specifically, two built-in rollers 320 are provided.

[0047] In this embodiment, the sealing mechanism 100 also includes at least one sealing roller 114 arranged between the cleaning belt 200 and the sealing member 110; the sealing roller 114, the sealing member 110, the cleaning belt 200 and the two baffles 120 together form a closed self-cleaning chamber 101.

[0048] Specifically, one sealing roller 114 is provided, and a plurality of sealing rollers 114 may be provided depending on the situation.

The contact between the cleaning belt 200 and the sealing roller 114 is surface contact. This contact surface plays an important sealing role. It can avoid water leakage due to the jumping between the cleaning belt 200 and the sealing roller 114 caused by rigid contact between the two or shaking during the use of the contact cleaning device; further, between the sealing mechanism 100 and the cleaning belt 200, between the sealing mechanism 100 and the sealing roller 114, and between the cleaning belt 200 and the sealing mechanism 100, at least one side of the outer surfaces that are tightly pressed together are flexible surfaces (the same applies to the following embodiments).

Like this, it can be helpful to increase the length of the segment belt of the cleaning belt winding 200 in the self-cleaning position, and better clean the dirt in the closed self-cleaning chamber 101.

[0072] In this embodiment, the enclosure mechanism 100 includes an enclosure member 110 and two baffles 120;

[0073] The enclosure member 110 and the cleaning belt 200 are both located between the two baffles 120;

[0074] The enclosing member 110 , the cleaning belt 200 and the two baffles 120 together form a closed self-cleaning chamber 101 .

[0075] In this embodiment, at the opening of the open ring formed by the outer ring surface of the belt section of the cleaning belt 200 at the cleaning position, specifically, the enclosing member 110 includes at least one sealing roller 150, each sealing roller 150 is arranged in sequence, and the central axis of the sealing roller 150 is parallel to the central axis of the built-in roller 320. Specifically, there is one sealing roller 150.

[0076] See also Figures 8 to 10 In this embodiment, the sealing mechanism 100 is provided with a pressing adjustment mechanism 600, which is used to adjust the extrusion force on the outer ring belt surface of the belt section of the cleaning belt 200 in the self-cleaning position. In this way, the extrusion force on the outer cylindrical surface of the cleaning belt 200 in the self-cleaning position when entering and moving out of the self-cleaning position can be adjusted and controlled under the interaction of the sealing mechanism 100. Specifically, the relative pressing force between the two column rollers 310 and the sealing roller 150 between them.

[0077] Specifically, two rollers are provided, and the column end of the built-in roller 320 has a bearing 690. The clamping adjustment mechanism 600 includes a first radial locking ring 610, a second radial locking ring 620, a first clamping force spring 630, a second clamping force spring 640, a clamping force wrench 650, and a clamping force adjustment bolt 660. The first radial locking ring 610 and the first clamping force spring 630 are locked and connected by rotating 90 degrees through the first locking buckle 681, and then rotated 90 degrees through the first locking buckle 681 to unlock and disengage, so that the first radial locking ring 610 disengages the bearing 690 of the corresponding built-in roller 320 to load or remove the corresponding built-in roller 320, such as Fig. 9 As shown; similarly, the second radial locking ring 620 and the second clamping force spring 640 are locked and connected by rotating the second locking buckle 682 90 degrees, and then unlocked and disengaged by rotating the second locking buckle 682 90 degrees, so that the second radial locking ring 620 is disengaged from the bearing 690 of the corresponding built-in roller 320 to install or remove the corresponding built-in roller 320.

[0078] At least one of the built-in rollers 320 is rotatably connected to one end of the first radial locking ring 610, and the rotation axis is parallel to the central axis of the built-in roller 320. The other end of the first radial locking ring 610 is connected to or disconnected from one end of one of the first clamping force springs 630 by a 90-degree rotation of the first lock buckle 681.

[0079] At least one of the built-in rollers 320 is rotatably connected to one end of the second radial locking ring 620, and the rotation axis is parallel to the central axis of the built-in roller 320. The other end of the second radial locking ring 620 and one end of another second clamping force spring 640 are connected or disconnected by a 90-degree rotation of the second lock buckle 682.

[0080] The other end of the first clamping force spring 630 is connected to the clamping force wrench 650;

[0081] The other end of the second clamping force spring 640 is connected to the clamping force wrench 650;

[0082] The clamping force wrench 650 is threadedly connected to the clamping force adjusting bolt 660 , wherein the distance between the clamping force wrench 650 and the first radial locking ring 610 and the distance between the clamping force wrench 650 and the second radial locking ring 620 can be adjusted by rotating the clamping force adjusting bolt 660 .

[0083] The lower end of the clamping force adjusting bolt 660 is connected to the steering member 670. When the clamping force adjusting bolt 660 rotates, the clamping force wrench 650 can be raised or lowered, thereby adjusting the distance between the column clamping force wrench 550 and the first column radial locking ring 510 and adjusting the distance between the column clamping force wrench 550 and the second column radial locking ring 520.

[0084] The clamping force wrench 650 is hinged on the baffle 120 through the clamping force adjusting bolt 660 and the steering member 670, and its upper end can be turned outward away from the baffle 120; when the upper end of the clamping force wrench 650 is vertically pressed inwardly against the baffle 120, the first clamping force spring 630 and the second clamping force spring 640 are in a long-distance state, and the spring force lifts the first radial locking ring 610 and the second radial locking ring 620 upward, so that the bearings of the two built-in rollers 320 are squeezed toward the sealing roller 150 and the external roller 420 at the same time, and the built-in roller 320 is pressed against the sealing roller 150 and the external roller 420. and its cleaning wrap 200 is pressed tightly against the sealing roller 150 and the external roller 420; when the upper end of the clamping force wrench 650 is pulled outward away from the baffle 120 and tilted outward, the first clamping force spring 630 and the second clamping force spring 640 are in a short-distance state and relaxed, and the first lock buckle 681 and the second lock buckle 682 can be rotated 90 degrees, so that the first clamping force spring 630 and the second clamping force spring 640 are disengaged from the first radial locking ring 610 and the second radial locking ring 620, and the built-in roller 320 is respectively installed or removed.

[0085] During specific use, the distance between the clamping force wrench 650 and the first radial locking ring 610 and the distance between the clamping force wrench 650 and the second radial locking ring 620 can be adjusted by rotating the clamping force adjusting bolt 660, thereby changing the spring force of the first clamping force spring 630 and the second clamping force spring 640, and adjusting the clamping force between the first radial locking ring 610 and the second radial locking ring 620 and the sealing roller 150. In this way, such a clamping force can always be found between the built-in roller 320 and the sealing roller 150, so that the clamping extrusion surface can squeeze out the moisture on the cleaning tape 200, making it moist and water-proof. It should be noted here that in a specific implementation, a sealing structure will be provided at the junction of the cleaning tape 200 and the enclosure 140 to achieve a sealed connection, wherein, for example Figure 8 As shown, at the junction of the cleaning belt 200 and the enclosure 140, the cleaning belt 200 can be set in a flange shape, and the enclosure 140 can be set in a smooth concave shape, which matches the flange of the cleaning belt 200 and seals, and sealing members can be set at both ends of the sealing roller 150 to seal the junction with the enclosure 140. When cleaning water is placed in the closed self-cleaning chamber 101, the cleaning belt 200 can be lubricated along its annular path, and the sealing roller 150 can be lubricated and rotated along its central axis. At the same time, the junctions with the enclosure 140 are sealed to construct the closed self-cleaning chamber 101. Among them, the external roller 420 is completely inside the closed self-cleaning chamber 101, and the internal roller 320 is completely outside the closed self-cleaning chamber 101, and it is not necessary to implement sealing between the enclosure 140.

[0086] After reasonably changing the sealing structure listed in this embodiment, it can be applied to other embodiments.

[0087] Embodiment 7
