Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of cleaning machines, in particular to a connecting guide baffle, a cleaning roller mechanism and a cleaning appliance. BACKGROUND

[0002] With the progress of science and technology, people's requirements for floor cleaning tools have gradually increased. A new cleaning mechanism has emerged, which uses a cleaning roller to adsorb dust on the cleaning surface, and then uses water to wash the cleaning roller to remove the dust from the cleaning roller. This mechanism is called "water dust circulation". Cleaning appliances using such a mechanism are also called "water dust circulation" scrubbers. The water dust circulation scrubber drives the cleaning cylinder to wipe the floor through the operation of the motor. The cleaning cylinder usually adopts a sponge cylinder structure, and the floor cleaning appliance is also equipped with a water supply system to clean the cleaning cylinder, thereby perfectly achieving the cleaning of the floor. In order to clean the cleaning cylinder, a closed cleaning space is usually provided to clean the local roller, clean water is provided to clean the cleaning cylinder, and then the sewage after cleaning the cleaning cylinder is pumped away.

[0003] Chinese patent document CN212698746U discloses a water pressing plate assembly for a cleaning tool, a cleaning head and a cleaning tool. The water pressing plate assembly comprises a water pressing plate comprising a transparent window, and a scraping strip connected to the water pressing plate. However, the arc-shaped working strip on the water pressing plate and the drainage part of the scraping strip are in interference fit with the sponge roller on the same side of the two points, and the interference fit part has a small amount of intermittent, which causes the fine particle garbage pulled up by the sponge roller to slowly accumulate at the place not in interference fit, and the accumulated place is blocked by the sponge roller as a whole inside the semi-closed space formed by the sponge roller and the shell, so that the accumulated fine particle garbage can only be cleaned by other tools after the sponge roller is disassembled. At the same time, due to the fact that the sponge roller is in a wet state during use, bacteria are easy to breed, and odor phenomenon occurs. Moreover, the place where the water pressing plate is in interference fit with the sponge roller is inside the semi-closed space formed by the sponge roller and the shell, so that it is very difficult to clean the accumulated fine particle garbage even after the sponge roller is disassembled. There is still a gap between the front end of the inner wall of the water pressing plate assembly and the surface of the sponge roller in a free state, and water will drip along the front end of the inner wall of the water pressing plate assembly to the cleaned floor when a large amount of water is used for mopping. Therefore, a technical solution is needed that can reduce the accumulation of fine particle garbage, facilitate the cleaning of the place where fine particle garbage accumulates, and prevent water from dripping to the floor when a large amount of water is used for mopping.

[0094] The scheme of the present application will be described in detail below in conjunction with the drawings.

[0095] As Figure 1As shown, the present invention provides a guide baffle, which is installed in a cleaning roller mechanism. The cleaning roller mechanism includes a cleaning roller 1 and a roller cover plate 2, and also includes a wringing strip 3 and a guide strip that form a cleaning surface contact with the surface of the cleaning roller. A guide baffle 4 is provided on the outside of the wringing strip, which contacts the surface of the cleaning roller. One end of the guide baffle is movably connected to the wringing strip, and the other end of the guide baffle is movably connected to the roller cover plate to improve the stability of the guide baffle during operation. A fixing member 5 is provided between the roller cover plate and the guide baffle for connecting and fixing the wringing strip. The fixing member includes a fixed end movably connected to the wringing strip and a free end connected to the guide baffle.

[0096] Example 1:

[0097] like Figure 2 As shown, for easy assembly and disassembly, one end of the guide baffle 4 is movably connected to the squeezing strip 3, and the other end of the guide baffle is movably connected to the roller cover plate 2 to improve the stability of the guide baffle during operation. A fixing member 5 for connecting and fixing the squeezing strip is provided between the roller cover plate and the guide baffle. The fixing member and the guide baffle support each other, and the space created by the support forms a variable cavity 6.

[0098] like Figure 3 As shown, to achieve a movable connection between one end of the guide baffle and the wringing strip, the wringing strip is provided with a fixing groove 38, and a fixing part 42 is provided on the corresponding wringing strip to movably connect and cooperate with the fixing groove. After the fixing part is inserted into the fixing groove, the guide baffle is fixed. The guide baffle includes a guide baffle body 45, and a fixing part 42 is provided at one end of the guide baffle. Specifically, the fixing part is a cylindrical shape extending outward from one end of the guide baffle body. The cylindrical surface of the fixing part can rotate slightly in the fixing groove 38 corresponding to the wringing strip. The side of the fixing groove that cooperates with the fixing part has a notch. The maximum width of the part where the fixing part connects with the guide baffle body is smaller than the minimum width of the notch. When the cleaning roller encounters an impact at high speed, the fixing part can further reduce the impact of the cleaning roller on the guide baffle through the notch of the fixing groove. Similarly, the auxiliary buffer of the guide baffle can further absorb the impact received by the cleaning roller. The guide baffle body is located at the lower end of the fixed part and has a flush end 44 that abuts against the squeezing part 31 of the squeezing strip. The depth of the flush end pressed into the surface of the cleaning roller is slightly lower than the depth of the squeezing part of the squeezing strip pressed into the surface of the cleaning roller. When the cleaning roller is running, starting from when the pressure surface of the cleaning roller passes the squeezing part 31, as the pressure surface of the cleaning roller passes the squeezing part 31 and the flush end 44 in sequence and continues to rotate, the force on the pressure surface of the cleaning roller caused by the squeezing strip or the guide baffle decreases in sequence. This is conducive to the slow release of the outward elastic force during the transition of the pressure surface of the cleaning roller from the compressed state to the free state, and can reduce the impact of the pressure surface of the cleaning roller on the outside.

[0099] In order to facilitate the cooperation with one end of the fixing member 5, as shown in the figure, the end of the extension baffle connected with the fixing member is provided with an elastic stretchable "U" shaped hook part 43, which is sleeved on the end of the fixing member extending to the surface of the cleaning roller, so as to realize the connection and fixation of the fixing member with the extension baffle. Figure 4

[0100] As shown in the figure, the hook part 43 is extended outward from the lowest part of the extension baffle body 45, and the "U" shaped hook part is "long outside and short inside", when installing the extension baffle, the chamfered part of the short inside can be used to abut against the corresponding outer edge of the fixing member 5 first, and then force is applied to the bottom of the "U" shaped part to push it to the opening direction of the "U" shaped part, so as to complete the clamping of the extension baffle 4 on one end of the fixing member 5 by the "U" shaped hook part 43. Figure 4

[0101] The lowest part of the extension baffle body 45 is the release end 40, when the cleaning roller rotates at high speed, the calculation starts from the extrusion part 31 through which the surface of the cleaning roller is pressed, when the surface of the cleaning roller is pressed successively through the extrusion part 31, the flush end 44, the arc surface of the extension baffle body 45 and the release end 40, and continues to rotate, the force from the extrusion strip or the extension baffle acting on the surface of the cleaning roller is successively reduced to zero, so as to facilitate the slow release of the outward elastic force in the process of the surface of the cleaning roller from the compressed state to the free state, and can reduce the impact of the surface of the cleaning roller to the outside.

[0102] As shown in the figure, Figure 2 , Figure 4 ​​As shown, the extension baffle body 45 has an arc surface that elastically adheres to the surface of the cleaning drum, and the arc surface starts from the flush end 44 to the release end 40. Because of the slight height difference or flush between the squeezing part of the squeezing strip and the flush end 44 of the extension baffle body, and the different reaction forces of the surface of the cleaning drum under the compression of different materials, when the surface of the cleaning drum passing through the critical surface of the squeezing part 31 and the flush end 44, the reaction force of the cleaning drum has a sudden change, at this moment, the surface of the cleaning drum is subjected to the maximum force of the arc surface of the extension baffle body. When the surface of the cleaning drum continues to rotate along the arc surface of the extension baffle body 45, the surface of the cleaning drum continues to recover to the free state, and the impact force of the surface of the cleaning drum is neither too large nor too small during the recovery process, that is, the part that is bounced too much is just absorbed by the arc surface of the extension baffle body 45, and the arc surface of the extension baffle body 45 does not additionally prevent the surface of the cleaning drum from continuing to recover to the free state. When the surface of the cleaning drum leaves the release end 40 of the extension baffle body 45, the force of the extension baffle acting on the surface of the cleaning drum is zero. The above process is the process that the reaction force of the arc surface of the extension baffle body 45 acting on the surface of the cleaning drum decreases uniformly from the peak value to zero after the surface of the cleaning drum passing through the critical surface of the squeezing part 31 and the flush end 44. When the outer diameter of the cleaning drum is a fixed value and the arc length of the arc surface of the extension baffle body 45 is also a fixed value, the compression amount of each point of the cross section of the arc surface of the extension baffle body 45 relative to the free state of the surface of the cleaning drum is also a fixed value, and then the arc surface of the extension baffle body 45 should be uniquely determined. This process is somewhat similar to a ping-pong ball on a lead hammer being thrown up, and a top player uses the same lead hammer to hit the ping-pong ball with the same acceleration to make the ping-pong ball descend, and the player adjusts the angle of the racket surface during the process of descending, and the ping-pong ball does not bounce up and leave the racket surface due to the compression of the ping-pong ball or the racket. After the completion of the “lead surface ball fishing” action of the top player, the ping-pong ball is stationary on the racket surface parallel to the horizontal plane.

[0103] The surface of the middle part of the extension baffle body 45 opposite to the fixing part 5 extends upward by several elastic pressing strips 49, and the top surface of the elastic pressing strip abuts against the fixing part 5. In this way, the space supported by the several elastic pressing strips 49 between the fixing part and the extension baffle forms a variable cavity 6. In order to achieve a better rebound effect, the elastic pressing strips are vertically and spaced apart in the horizontal plane with the ground as the horizontal line. The design of the elastic pressing strips can provide a larger deformation space for the extension baffle, and at the same time reduce the stress of the cleaning drum. When an external force is transmitted to the fixing part through the drum cover, due to the design of the elastic pressing strips, the external force received by the squeezing strip can be effectively dispersed, so as not to affect the normal work of the cleaning drum.

[0104] In detail, as shown in Figure 2 , Figure 4 , the fixing part 42 is first clamped in the fixing groove 38, then the hook part 43 in the connecting and blocking plate is stretched, and one end of the fixing part 5 is sleeved in the hook part.

[0105] In order to smoothly separate the debris and garbage from the surface of the cleaning roller when the connecting and blocking plate contacts the surface of the cleaning roller after being pressed by the water squeezing strip, the cross section of the connecting and blocking plate is designed as an arc shape suitable for the surface of the cleaning roller.

[0106] In this embodiment, as shown in Figure 3 , Figure 4 , the connecting and blocking plate and the water squeezing part 31 of the water squeezing strip have a small height difference, and when in use, the connecting and blocking plate contacts the surface of the cleaning roller after being pressed by the water squeezing strip, and the garbage such as debris generated from the surface of the cleaning roller after being pressed is separated from the cleaning roller, so that fine particle garbage is not accumulated at the rear end of the water squeezing strip, and the odor generated by the cleaning roller mechanism is reduced.

[0107] As shown in Figure 5 , the connecting and blocking plate is an integral structure, and a plurality of elastic pressing strips 49 extending upward from the plumb are distributed on the surface of the connecting and blocking plate body.

[0108] As a preferred embodiment, the shape of the elastic pressing strip 49 abutting on the fixing part 5 is rectangular.

[0109] As a preferred embodiment, the shape of the elastic pressing strip 49 abutting on the fixing part 5 is circular.

[0110] As a preferred embodiment, the shape of the elastic pressing strip 49 abutting on the fixing part 5 is triangular.

[0111] As a preferred embodiment, the shape of the elastic pressing strip 49 abutting on the fixing part 5 is S-shaped.

[0112] Embodiment two:

[0113] As shown in Figures 6-8As shown, the embodiment is different from the first embodiment in that the guide baffle 4 comprises a limiting portion 41 which is a protruding structure. In this solution, the end face of the protruding structure is arc-shaped. The arc-shaped protruding end face of the limiting portion abuts against the fixing member 5. In this embodiment, the arc-shaped protruding end face of the limiting portion abuts against the middle portion of the fixing member (the length of the fixing member is the length between the free end and the fixed end, and the fixed end is the abutting end of the fixing member which abuts against the first fixed portion and is close to the free end).

[0114] As shown in the drawings, Figure 7 In this embodiment, the guide baffle 4 is flush with the end face of the water squeezing portion 31 of the water squeezing strip. The water squeezing portion is provided with a guide portion 37 which is flush with the guide baffle and is smoothly connected with the guide baffle. The guide baffle is provided with a rotating fixing portion 42 which cooperates with the guide portion.

[0115] In order to achieve the flush end face effect, one end of the guide portion connected with the water squeezing portion is a fixed end, and the other end is a free end. The end face of the free end which contacts the surface of the cleaning roller forms a certain angle with the end face of the fixed groove. In this solution, the angle is preferably an acute angle. Correspondingly, a flush end 44 is arranged on the guide baffle. When the fixing portion 42 is clamped into the fixed groove 38, the flush end is just connected with the angle of the guide portion, so as to smoothly connect the guide baffle with the water squeezing strip.

[0116] Since the cleaning roller has a certain elasticity after being contacted with water, in order to prevent the garbage of the guide baffle and the water squeezing strip from being pressed against the surface of the cleaning roller during the working process, the end face of the water squeezing portion of the guide baffle and the water squeezing strip is flush. When used, the fine particle garbage at the rear end of the water squeezing strip will fall along with the roller and be recycled again, so as to reduce the accumulation of garbage. This design can reduce the garbage remaining in the cleaning roller mechanism and reduce the odor of the cleaning roller mechanism.

[0117] The lowest part of the guide baffle body 45 is the release end 40. Since the water squeezing strip is made of metal and is relatively hard, and the guide baffle is made of elastic material and is relatively soft, when the cleaning roller rotates at high speed, the force acting on the cleaning roller from the water squeezing strip or the guide baffle is gradually reduced to zero when the cleaning roller surface passes through the water squeezing part 31, the flush end 44, the arc surface of the guide baffle body 45, and the release end 40 in sequence. This is beneficial to the slow release of the outward elastic force during the process of the cleaning roller surface changing from the compressed state to the free state, and can reduce the impact of the cleaning roller surface on the outside. It should be noted that although the water squeezing part 31 and the flush end 44 are flush, the force acting on the cleaning roller from the elastic material of different materials is different when the cleaning roller is compressed to the same depth during operation. In order to alleviate the sudden change of the force acting on the cleaning roller at the critical interface, the hardness of the elastic material used for the guide baffle is as close as possible to the hardness of the metal used for the water squeezing strip.

[0118] As shown in Figure 8 , first, the fixed part 42 is clamped in the fixed groove 38, and then the entire guide baffle fixed part 42 is sequentially slid into the fixed groove 38. Unlike the first embodiment, the hook part of the guide baffle does not need to be clamped, which is much more convenient.

[0119] As shown in Figure 8 , at least two reinforcing ribs 46 are distributed on the surface of the guide baffle body, and the reinforcing ribs are distributed in parallel.

[0120] As a preferred embodiment, the reinforcing ribs 46 on the surface of the guide baffle body extend from the end of the guide baffle connected to the water squeezing strip to the hook part 43 along the circumferential direction of the cleaning roller.

[0121] As a preferred embodiment, the reinforcing ribs 46 on the surface of the guide baffle body extend from the end of the guide baffle connected to the water squeezing strip to the hook part 43 along the direction of the tangent to the elliptical trajectory formed by the cleaning roller.

[0122] Of course, the reinforcing ribs 46 distributed on the surface of the guide baffle body can also be irregular non-parallel reinforcing ribs (not shown in the figure), or continuous "S" type or "M" type or "N" type reinforcing ribs (not shown in the figure) with equal spacing between them.

[0123] Example Three:

[0124] As shown in Figures 9-13As shown, the embodiment is different from the first and second embodiments in that a plurality of fixing buckles 47 are arranged between the reinforcing ribs, and a plurality of fixing holes 51 corresponding to the fixing buckles 47 are arranged on the fixing member 5 connected with the guide baffle 4. In order to facilitate the connection of the fixing buckles 47 and the fixing holes 51, a fixing sliding groove 52 extends along the fixing hole 51 to the edge of the fixing member 5, and the fixing buckle 47 can slide along the fixing sliding groove 52 from the edge of the fixing member 5 to the fixing hole 51. In order to prevent the fixing buckle 47 from falling off the fixing hole 51.

[0125] As shown in the drawings, Figure 12 the fixing buckle 47 is designed as a structure with a wide upper part and a narrow lower part. The fixing buckle specifically includes a stop head 471, a stop rod 472, and a stop transition zone 473. The stop rod 472 extends outward from the guide baffle body 45, and one end of the stop rod 472 is connected integrally with the guide baffle body 45. The other end of the stop rod 472 is connected with the stop transition zone 473. The part of the stop rod 472 that continues to extend outward toward the stop transition zone 473 is the stop head. A chamfer is arranged at the stop transition zone between the stop head and the stop rod.

[0126] As shown in the drawings, Figure 9 , Figure 12 the fixing buckle of the guide baffle presents a similar "T" shape structure (not marked in the drawings) in the illustrated cross section. The stop rod 472 extends outward from the guide baffle body 45, and one end of the stop rod 472 is connected integrally with the guide baffle body 45. The other end of the stop rod 472 is connected with the stop transition zone 473. The part of the stop rod 472 that continues to extend outward toward the stop transition zone 473 is the stop head 471. The fixing buckle 47 of the guide baffle 4 presents a similar "T" shape structure (not marked in the drawings) in the direction of the reinforcing rib 46 when viewed from the fixing buckle 47. Figure 12

[0127] As shown in the drawings, Figure 13 the corresponding fixing sliding groove 52 is adapted to the stop rod 472, facilitating the stable cooperation of the fixing buckle 47 and the fixing hole 51, and facilitating the assembly of the two. In order to facilitate the connection of the fixing buckle 47 and the fixing hole 51, the fixing sliding groove 52 extends along the fixing hole 51 to the edge of the fixing member 5, and the stop rod 472 can slide along the fixing sliding groove 52 from the edge of the fixing member 5 to the fixing hole 51. At the same time, the stop head 471 is clamped on the outer surface of the fixing member 5 above the fixing hole 51 by means of the stop transition zone 473.

[0128] In this embodiment, the structure of the fixing buckle 47 is not limited to Figure 1 , Figure 9 , Figure 10 , Figure 12 , Figure 13 ​The hook structure can be a hook or any other structure that can be connected with the fixing hole and is not easy to fall off.

[0129] In the prior art, as shown in Figure 2 、 Figure 6 、 Figure 14 When the water flow through the filter hole is too large, the water is easy to overflow the wringing strip, flow along the back plate of the wringing strip, and drip along the cleaner head shell to the floor or drip down along the cleaner head shell, thereby forming water accumulation on the floor. This water leakage problem not only affects the cleaning effect of the cleaning appliance but also causes a poor experience for the customer. In addition, fine particle garbage along the water flow is easy to accumulate on the cleaner head shell, thereby causing odor.

[0130] To solve the above technical problems, as shown in Figure 9 、 Figure 11 、 Figure 13 The hook portion 43 cooperates with one end of the fixing member 5, thereby ensuring that the water overflowing the wringing strip always stays between the guide baffle and the fixing member. When the water flows through the drain hole 48, the water flow passes through the drain hole to the surface of the cleaning roller because the drain hole is in contact with the surface of the cleaning roller. Because the cleaning roller is a soft and water-absorbing material, it can quickly absorb the water dripping through the drain hole, thereby solving the technical problem of water dripping along the cleaner head shell directly to the floor.

[0131] As shown in Figure 3 、 Figure 9 、 Figure 10 、 Figure 13 In the embodiment, the guide baffle 4 and the wringing strip 3 are detachably connected. When fine particle garbage in the water flow adheres to the guide baffle body 45 or the hook portion 43, the guide baffle 4 can be disassembled and washed, thereby effectively preventing odor caused by long-term accumulation of fine particle garbage. The fixing sliding groove 52 on the fixing member 5 is adapted to the stop rod 472 on the guide baffle 4, which facilitates stable cooperation of the fixing buckle 47 and the fixing hole 51 and facilitates assembly and fixation of the two. In order to facilitate connection and fixation of the fixing buckle 47 and the fixing hole 51, the fixing sliding groove 52 extends through along the edge of the fixing hole 51 to the edge of the fixing member 5. The fixing buckle 47 on the guide baffle 4 presents a similar “T” shape structure in both views, which facilitates sliding of the stop rod 472 from the edge of the fixing member 5 along the fixing sliding groove 52 to the fixing hole 51. Meanwhile, the stop head 471 is clamped on the outer surface of the fixing member 5 above the fixing hole 51 by means of the stop transition area 473.

[0132] As shown in Figure 10 、 Figure 11As shown, the number of fixed buckles 47 in this embodiment is multiple, and the number of water outlets 48 is one less than the number of fixed buckles 47 (for example, when the number of fixed buckles is 6, the number of water outlets is 5), and the water outlets 48 are respectively distributed between the corresponding two fixed buckles 47. Of course, the water outlets 48 can also be arranged between the reinforcing ribs 46, at this time the water flow can flow along the reinforcing ribs 46 and directly flow out through the water outlet 48.

[0133] In this embodiment, the water outlet 48 is preferably arranged in a row, and of course it can also be arranged in multiple rows or columns in a staggered manner, as long as it can facilitate the water flow to quickly flow out through the water outlet 48.

[0134] As shown in Figure 1 , Figure 3 , Figure 7 , Figure 9 As shown in this embodiment, the height difference between the lead-in baffle 4 and the water squeezing part 31 of the water squeezing strip 3 is small or flush, so that fine particle garbage will not form an accumulation at the rear end of the water squeezing strip 3, reducing the odor generated by the cleaning roller mechanism, and at the same time, the hook part 43, the fixed buckle 47, the fixed hole 51 and the water outlet 48 structure designed on the lead-in baffle 4 can effectively prevent the problem of water flowing over the water squeezing strip 3 and dripping along the cleaning head shell, and also avoid the fine particle garbage flowing out along the water flow from piling up on the cleaning head shell, reducing the odor generated by the cleaning roller mechanism.

[0135] Embodiment Four:

[0136] As shown in Figure 14 The difference between this embodiment and embodiment one, embodiment two and embodiment three is that in this embodiment, the fixed part 5 and the lead-in baffle 4 are connected by screws, of course, the connection mode of the two in this embodiment is not limited, as long as the detachable connection mode in the art can be used as an alternative scheme in this embodiment. In order to achieve seamless connection between the lead-in baffle 4 and the water squeezing strip 3, the lead-in baffle 4 and the water squeezing strip 3 are connected by adhesion in this embodiment, through the above two connection modes, the seamless connection between the lead-in baffle 4 and the water squeezing strip 3 can be achieved, and at the same time, the height difference between the lead-in baffle 4 and the water squeezing strip 3 is small or close to flush.

[0137] Compared with embodiment one, embodiment two and embodiment three, another difference is that there is no elastic pressing strip structure design in this embodiment, but the inside of the lead-in baffle can still be designed as a variable cavity 6 structure, the other end of the lead-in baffle 4 away from the water squeezing strip 3 is free to abut against the cleaning roller 1, or a protrusion can be provided at the terminal end of the end face, the protrusion abuts against the fixed part, when the fixed part 4 deforms, the protrusion structure design can achieve a certain buffering effect, thereby reducing the force between the lead-in baffle 4 and the cleaning roller 1, ensuring the normal work of the cleaning roller 1.

[0138] Similarly, one end of the fixing member 4 abuts against the protruding part of the connecting baffle 4, giving it more space for movement and deformation. The other structures are the same as in the first embodiment, and will not be repeated here.

[0139] The above design also meets the requirement that the connecting baffle 4 contacts the surface of the cleaning roller after being extruded by the water extrusion strip 3 during use, and separates the garbage such as debris generated after extrusion from the surface of the cleaning roller 1. Because there is a small height difference or almost no difference between the connecting baffle 4 and the water extrusion strip 3 in this embodiment, fine particle garbage will not accumulate at the rear end of the water extrusion strip, reducing the odor generated by the cleaning roller mechanism.

[0140] According to an embodiment of the present application, a cleaning roller mechanism is provided, comprising the connecting baffle described above.

[0141] According to an embodiment of the present application, a cleaning appliance is provided, comprising the cleaning roller mechanism described above.

[0142] According to an embodiment of the present application, during the operation of the cleaning appliance, the cleaning roller rotates, garbage is rolled up by the cleaning roller, and at the same time, clean water is delivered to the surface of the cleaning roller to flush the cleaning roller. The upper part of the cleaning head housing is provided with a water extrusion strip, the water extrusion strip and the cleaning roller are in interference fit, and the sewage extruded by the water extrusion strip and the clean water delivered to the cleaning roller are mixed together during high-speed rotation of the cleaning roller, and a part of the garbage is carried away by the water flow. The part of the cleaning roller rotating through the water extrusion part of the water extrusion strip will recover to the normal surface shape without pressure under the elasticity of the material of the cleaning roller itself, and the connecting baffle just absorbs the impact generated during the recovery of the part of the cleaning roller surface. The part of the cleaning roller surface during the recovery process cannot throw out the "micro-particle" garbage mixed in the "clean surface" after "water extrusion", and naturally these "micro-particle" garbage cannot be deposited on the lower surface corresponding to the part of the cleaning roller surface without the connecting baffle. It can be widely used on cleaning appliances, which can be a dust collector, a floor washing machine or a sweeping robot product.

The cleaning roller mechanism is provided with the guide baffle on the side surface of the rear end of the water squeezing strip, the guide baffle has a small height difference with the water squeezing part of the water squeezing strip. In use, the guide baffle is in contact with the cleaning surface of the cleaning roller after being squeezed by the water squeezing strip, and garbage such as chippings generated from the cleaning surface of the cleaning roller after being squeezed is separated from the cleaning roller. When the height difference between the guide baffle at the rear end of the water squeezing strip and the water squeezing part of the water squeezing strip is small or zero, fine garbage is not accumulated at the rear end of the water squeezing strip, the cleaning roller mechanism is prevented from generating peculiar smell, the guide baffle can absorb the impact generated from the cleaning surface of the cleaning roller in the process of recovering the shape after being squeezed by the water squeezing strip, the guide baffle is convenient to disassemble and clean, and the guide baffle can solve the problem that water is dripped along the inner surface of the roller cover plate to the cleaned ground when a large amount of water is used for mopping. The cleaning appliance can be a dust collector, a floor washing machine or a sweeping robot.
