Description

Technical Field

[0001] The present application relates to the technical field of the water blocking system of a floor washer, and particularly relates to a lifting water blocking system and a floor washer using the system. Background Art

[0002] As an important cleaning device, a floor washer is widely used in commercial, industrial, and household fields. Its core function is to achieve efficient cleaning of the ground and sewage collection through the coordinated action of a floor scrubbing component and a water blocking component.

[0003] The existing sewage collection method of the floor scrubbing brush of a floor washer is as follows: the floor scrubbing brush is provided with a water baffle, and after blocking the sewage, it is transferred to the water suction squeegee at the rear to complete the collection by the water suction squeegee. However, this water baffle is usually of a fixed structure and needs to be adjusted regularly according to the wear condition of the floor scrubbing brush; moreover, the adjustment effect of the water baffle is also affected by the experience of the operator: if the water blocking rubber is not pressed down enough, the water scraping effect is poor; if the water blocking rubber is pressed down too much, not only the water scraping effect is poor, but also the water blocking rubber is easily rolled under the floor scrubbing disc, accelerating the wear. Summary of the Invention

[0004] In order to overcome the problems mentioned above, the present application provides a lifting water blocking system and a floor washer using the system.

[0005] In a first aspect, a lifting water blocking system provided by the present application adopts the following technical solution: A lifting water blocking system includes a brush disc frame, two water blocking frames symmetrically arranged on both sides of the brush disc frame, a connecting rod assembly connected to each water blocking frame, a water blocking component connected to the end of the connecting rod assembly far away from the water blocking frame, an elastic member connected between the connecting rod assembly and the water blocking component, and a limiting member arranged on the water blocking frame for limiting the connecting rod assembly. The water blocking component is connected to the water blocking frame through the connecting rod assembly to form a parallelogram structure, so that the connecting rod assembly can drive the water blocking component to swing in a direction close to or away from the water blocking frame. The elastic member is used to pull the water blocking component to move in a direction away from the water blocking frame to provide a downward pressure for the water blocking component. The limiting member is used to limit the swinging range of the connecting rod assembly, and the water blocking part of the water blocking component is turned outwards at a predetermined angle.

[0006] By adopting the above technical solution, the water retaining component, the connecting rod component and the water retaining frame form a parallelogram structure, enabling the connecting rod component to drive the water retaining component to swing towards or away from the water retaining frame, thereby realizing the position adjustment function of the water retaining component; the elastic member pulls the water retaining component to move away from the water retaining frame, providing a stable downward pressure for the water retaining component and ensuring the contact effect between the water retaining component and the ground; the limiting member restricts the swinging range of the connecting rod component, effectively reducing the structural failure caused by excessive swinging of the water retaining component; the water retaining part of the water retaining component is turned outwards at a predetermined angle, improving the water scraping effect and reducing the risk of the water retaining part being caught under the floor washing brush, thus overall enhancing the sewage collection efficiency and cleaning effect.

[0007] Optionally, one end of the water retaining frame is hinged to the brush disc frame, and the other end of the water retaining frame is locked to the brush disc frame.

[0008] By adopting the above technical solution, one end of the water retaining frame is hinged to the brush disc frame, enabling the water retaining frame to flip relative to the brush disc frame, so that the water retaining frame can be turned up when needed, facilitating the cleaning and maintenance of the area between the brush disc frame and the water retaining frame; the other end of the water retaining frame is locked to the brush disc frame, ensuring that the water retaining frame can be firmly fixed on the brush disc frame during operation, effectively reducing the loosening or flipping of the water retaining frame caused by external forces, and thus guaranteeing the stability and reliability of the water retaining component and enhancing the cleaning effect and operation stability of the overall system.

[0009] Optionally, the connecting rod component includes a first connecting rod and a second connecting rod arranged in parallel with each other. The top ends of the first connecting rod and the second connecting rod are both hinged to one side of the water retaining frame close to the brush disc frame, and the bottom ends of the first connecting rod and the second connecting rod are both hinged to the water retaining component. The first connecting rod and the second connecting rod can drive the water retaining component to swing towards or away from the water retaining frame.

[0010] By adopting the above technical solution, the first connecting rod and the second connecting rod are arranged in parallel with each other and are respectively hinged to the water retaining frame and the water retaining component to form a parallelogram structure; this structure enables the connecting rod component to drive the water retaining component to swing towards or away from the water retaining frame, thereby realizing the flexible adjustment of the position of the water retaining component; this design not only improves the adaptability of the water retaining component but also ensures the stable operation of the water retaining component under different working conditions, enhancing the reliability of the overall system.

[0011] Optionally, the water retaining component includes a water retaining plate hinged to the first connecting rod and the second connecting rod, a pressure strip detachably connected to the water retaining plate, and a water retaining rubber strip clamped between the water retaining plate and the pressure strip. An outwardly turned part is formed on the bottom surface of the water retaining plate at a predetermined angle.

[0012] By adopting the above technical scheme, the water retaining assembly consists of a water retaining plate, a pressure strip and a water retaining rubber strip, wherein the water retaining plate is hinged to the first connecting rod and the second connecting rod, so that the water retaining assembly can move with the swing of the connecting rod assembly; the water retaining rubber strip between the water retaining plate and the pressure strip plays an actual water retaining role, and at the same time, the outward-turning portion formed on the bottom surface of the water retaining plate makes the part of the water retaining rubber strip in contact with the ground turn outward at a predetermined angle, thereby maintaining the best scraping effect, effectively reducing the possibility of the water retaining rubber strip being rolled under the floor scrubbing brush, and improving the sewage collection efficiency and cleaning effect.

[0013] Optionally, the rear ends of the water baffle plate and the pressure strip are both formed with bent portions bent toward the brush disc frame, and the bent portions on both sides of the brush disc frame form an end for the brush disc frame.

[0014] By adopting the above technical solution, the setting of the bending part enables the water retaining components located on both sides of the brush plate frame to effectively gather sewage during operation to form a closing structure, thereby improving the sewage collection efficiency and minimizing sewage overflow.

[0015] Optionally, a guide wheel is installed on one end of the water baffle plate close to the brush plate frame.

[0016] By adopting the above technical solution, the setting of the guide wheel makes it possible to limit the maximum downward pressure of the water-retaining rubber strip when the water-retaining rubber strip contacts the ground and is subjected to pressure, thereby ensuring that the water-retaining rubber strip maintains an optimal downward pressure angle; during the backward movement of the brush disc frame, the friction between the water-retaining rubber strip and the ground may cause the connecting rod assembly to tend to swing downward, thereby hindering the movement of the brush disc frame; at this time, the guide wheel effectively offsets the swinging tendency of the connecting rod assembly by rolling, thereby ensuring the smooth operation of the equipment and improving the overall cleaning efficiency and stability.

[0017] Optionally, an adjustment component for adjusting the limit member is provided on the water retaining frame.

[0018] By adopting the above-mentioned technical scheme, the adjustment assembly can change the relative position of the limiter and the connecting rod assembly, thereby controlling the swing range of the connecting rod assembly; this adjustability enables the water retaining assembly to maintain stable operation under different working conditions, effectively reducing the reduced wiping effect or structural instability caused by excessive swing of the connecting rod assembly, thereby improving the adaptability and reliability of the entire lifting and water retaining system.

[0019] Optionally, the elastic member is a tension spring, an extension portion is formed at the bottom end of the second connecting rod, one end of the tension spring is hooked on the extension portion, a fixed block is fixedly connected to the side of the water retaining plate away from the water retaining rubber strip, and one end of the tension spring away from the extension portion is hooked on the fixed block.

[0020] By adopting the above technical solution, the tension spring as an elastic member can continuously provide stable tension, pull the water retaining plate to move away from the water retaining frame, and thus provide reliable downward pressure for the water retaining strip. Specifically, one end of the tension spring is hooked to the extension at the bottom end of the second connecting rod, and the other end is hooked to the fixed block on the side of the water retaining plate away from the water retaining strip. This connection method ensures the stable transmission of the tension spring force, so that the water retaining strip can fit closely to the ground and enhance the scraping effect; at the same time, the design can also automatically adapt to the wear of the floor scrubbing brush, always keep the water retaining strip in the best working state, and further improve the sewage collection efficiency and cleaning effect.

[0021] Optionally, the water retaining rubber strip is provided with a plurality of adjustment openings which are distributed at equal intervals and located on the same vertical line, and a plug-in block which is plug-in-matched with the adjustment opening is formed on one side of the water retaining plate close to the water retaining rubber strip.

[0022] By adopting the above technical solution, multiple adjustment openings that are evenly spaced and located on the same vertical line cooperate with the plug-in blocks on the water retaining plate to fix the water retaining strips at different heights, thereby adjusting the height of the water retaining strips according to actual usage needs to adapt to different ground environments or cleaning requirements.

[0023] In a second aspect, the present application provides a floor scrubber using a lifting water retaining system, comprising a floor scrubber body and a squeegee arranged on the bottom surface of the floor scrubber body and located on the rear side of the floor scrubber body, the squeegee being used to collect sewage behind the front water retaining assembly.

[0024] By adopting the above technical solution, the floor scrubber utilizes the lifting and water retaining system to effectively block and collect sewage.

[0025] In summary, the present application includes at least one of the following beneficial technical effects: 1. The water retaining assembly, the connecting rod assembly and the water retaining frame form a parallelogram structure, so that the connecting rod assembly can drive the water retaining assembly to swing in the direction close to or away from the water retaining frame, thereby realizing the position adjustment function of the water retaining assembly; the elastic member pulls the water retaining assembly to move in the direction away from the water retaining frame, providing a stable downward pressure for the water retaining assembly, and ensuring the contact effect between the water retaining assembly and the ground; the limiter limits the swing range of the connecting rod assembly, effectively reducing the structural failure caused by excessive swinging of the water retaining assembly; the water retaining part of the water retaining assembly is turned outward at a predetermined angle, which improves the scraping effect, reduces the risk of the water retaining part being rolled under the scrubbing brush, and improves the sewage collection efficiency and cleaning effect as a whole; 2. The setting of the bending part enables the water retaining components located on both sides of the brush plate frame to effectively gather sewage during operation to form a closing structure, thereby improving the sewage collection efficiency and minimizing sewage overflow; 3.

[0036] The following further describes the present application in detail with reference to the Figures 1 - 9 accompanying drawings.

[0037] An embodiment of the present application discloses a lifting water retaining system. Referring to Figure 1 and Figure 2 , the lifting water retaining system includes a brush tray 1, two water retaining brackets 2 symmetrically arranged on both sides of the brush tray 1, a connecting rod assembly connected to each water retaining bracket 2, a water retaining assembly connected to the end of the connecting rod assembly away from the water retaining bracket 2, an elastic member 3 connected between the connecting rod assembly and the water retaining assembly, and a limiting member 4 arranged on the water retaining bracket 2 for limiting the swinging range of the connecting rod assembly. The water retaining assembly is connected to the water retaining bracket 2 through the connecting rod assembly to form a parallelogram structure, so that the connecting rod assembly can drive the water retaining assembly to swing in a direction close to or away from the water retaining bracket 2. The elastic member 3 is used to pull the water retaining assembly to move away from the water retaining bracket 2, so as to provide a downward pressure for the water retaining assembly; the limiting member 4 is used to limit the swinging range of the connecting rod assembly. The water retaining part of the water retaining assembly is turned outwards at a predetermined angle, so as to maintain the best water scraping effect and achieve the effect of stable operation under various working conditions.

[0038] Referring to Figure 2 and Figure 3 , flanges 11 bent downward are formed on the front side and the rear side of the brush tray 1. A clamping plate 111 is detachably connected to the side of the flange 11 away from the brush tray 1. A blocking plate 112 is clamped between the flange 11 and the clamping plate 111. A fixing member 113 connected to the flange 11 is arranged on the clamping plate 111. One end of the fixing member 113 sequentially passes through the clamping plate 111 and the blocking plate 112 and is threadedly connected to the flange 11. In this embodiment, the fixing member 113 is a fixing bolt, and the blocking plate 112 is a rubber plate.

[0039] Two sets of floor scrubbing assemblies arranged in a front-back staggered manner are arranged on the brush tray 1. A water supply assembly for supplying water to the floor scrubbing ends of the two sets of floor scrubbing assemblies is arranged on the top surface of the brush tray 1; the water supply assembly supplies water to the floor scrubbing ends of the floor scrubbing assemblies, so that the floor scrubbing ends of the floor scrubbing assemblies can achieve a better cleaning effect.

[0040] Referring to Figure 4 and Figure 5, the floor scrubbing assembly includes a driving member 12 vertically installed on the top surface of the scrubbing brush holder 1, and a floor scrubbing brush 121 located on the bottom surface of the scrubbing brush holder 1 and connected to the driving end of the driving member 12; the driving end of the driving member 12 vertically penetrates the scrubbing brush holder 1, and a mounting seat 122 is detachably connected to the driving end of the driving member 12. The mounting seat 122 is sleeved on the periphery of the driving end of the driving member 12, and a mounting member 123 threadedly connected to the driving end of the driving member 12 is inserted through the bottom surface of the mounting seat 122, so as to realize the detachable connection between the mounting seat 122 and the driving end of the driving member 12; the floor scrubbing brush 121 is fixedly nested on the periphery of the mounting seat 122, so that the driving end of the driving member 12 drives the floor scrubbing brush 121 to rotate through the mounting seat 122. A plurality of water through holes 124 are arranged on the mounting seat 122 at equal intervals and vertically penetrate the mounting seat 122, and the water supply end of the water supply assembly supplies water to the floor scrubbing brush 121 through the water through holes 124.

[0041] Refer to Figure 3 and Figure 5 , the water supply assembly includes a water pump 13 installed on the top surface of the scrubbing brush holder 1, a water suction pipe 131 fixedly connected to the water inlet end of the water pump 13, a tee pipe 132 fixedly connected to the water outlet end of the water pump 13, and two water inlet pipes 133 respectively connected to the tee pipe 132; a water tank (not shown in the figure) is installed on the top surface of the scrubbing brush holder 1, and one end of the water suction pipe 131 away from the water pump 13 extends to the inner bottom wall of the water tank, so as to supply water to the water suction pipe 131 through the water tank; the two water inlet pipes 133 are respectively fixedly connected to the other two interfaces of the tee pipe 132, and one end of the water inlet pipe 133 away from the tee pipe 132 obliquely penetrates the top surface of the scrubbing brush holder 1 and extends above the mounting seat 122.

[0042] Refer to Figure 4 , connection seats 14 are fixedly connected to both corners on the front side of the scrubbing brush holder 1 on the top surface of the scrubbing brush holder 1. Hinges 21 corresponding to the positions of the connection seats 14 are installed on the water retaining frame 2. One side of the hinge 21 away from the water retaining frame 2 is installed on the connection seat 14. Through the connection between the hinge 21 and the connection seat 14, the water retaining frame 2 is hinged to the scrubbing brush holder 1, so that the water retaining frame 2 can be flipped relative to the scrubbing brush holder 1 with the hinge 21 as the hinge point.

[0043] Fixed seats 15 are fixedly connected to both corners on the rear side of the scrubbing brush holder 1 on the top surface of the scrubbing brush holder 1. A buckle lock 22 corresponding to the position of the fixed seat 15 is arranged on the water retaining frame 2. The locking end of the buckle lock 22 is connected to the fixed seat 15 to lock the water retaining frame 2 on the scrubbing brush holder 1, so that the water retaining frame 2 cannot be flipped.

[0044] Refer to Figure 4 and Figure 6, the connecting rod assembly includes a first connecting rod 23 and a second connecting rod 24; the first connecting rod 23 and the second connecting rod 24 are arranged in parallel; the top ends of the first connecting rod 23 and the second connecting rod 24 are both hinged to one side of the water baffle 2 close to the brush disc holder 1, and the bottom ends of the first connecting rod 23 and the second connecting rod 24 are both hinged to the water blocking assembly. The connection points of the first connecting rod 23 with the water baffle 2 and the water blocking assembly, and the connection points of the second connecting rod 24 with the water baffle 2 and the water blocking assembly form a parallelogram structure, so that the first connecting rod 23 and the second connecting rod 24 can drive the water blocking assembly to swing towards or away from the water baffle 2.

[0045] The water blocking assembly includes a water baffle 5, a bead 51 and a water blocking rubber strip 52 clamped between the water baffle 5 and the bead 51; wherein, the water baffle 5 is located on the side of the water blocking rubber strip 52 close to the brush disc holder 1. The bottom ends of the first connecting rod 23 and the second connecting rod 24 are both hinged to the side of the water baffle 5 far from the water blocking rubber strip 52; a connecting portion 511 bent is formed at the front end of the bead 51, and a socket 512 is opened on the connecting portion 511. A plugging portion 53 corresponding to the position of the socket 512 is formed at the front end of the water baffle 5. Under the plugging action of the plugging portion 53 and the socket 512, the front ends of the water baffle 5 and the bead 51 are connected.

[0046] Bent portions 54 bent towards the direction close to the brush disc holder 1 are formed at the rear ends of both the water baffle 5 and the bead 51. A sub-lock 513 is installed on the bent portion 54 located on the bead 51, and a female lock 541 corresponding to and matching the position of the lock is fixed on the bent portion 54 located on the water baffle 5. The sub-lock 513 and the female lock 541 are latched to fix the water blocking rubber strip 52 between the water baffle 5 and the bead 51. At the same time, due to the existence of the bent portion 54, the rear end of the water blocking rubber strip 52 is also bent, so that a closing opening is formed between the two sets of water blocking assemblies and at the bent portion 54 of the water blocking assembly, which is beneficial to the convergence and collection of sewage.

[0047] In order to be able to adjust the height of the water blocking rubber strip 52, a plurality of adjustment openings 521 are arranged at equal intervals on the water blocking rubber strip 52; the plurality of adjustment openings 521 are located on the same vertical line; a plugging block that is inserted and matched with the adjustment openings 521 is formed on the side of the water baffle 5 close to the water blocking rubber strip 52. When the plugging block is inserted into the adjustment openings 521 at different heights, the adjustment of the height of the water blocking rubber strip 52 is realized. At the same time, in order to make the water blocking rubber strip 52 be clamped more firmly between the bead 51 and the water baffle 5, in this embodiment, a plurality of plugging blocks are provided, and the plurality of plugging blocks are arranged at equal intervals in the horizontal direction on the water baffle 5. The number of the adjustment openings 521 in the same horizontal direction is the same as and corresponds to the number of the plugging blocks one by one.

[0048] On the bottom surface of the water baffle 5, an outward-turned portion 55 is formed and is inclined obliquely. The outward-turned portion 55 is turned outward at a predetermined angle; and the inclination direction of the outward-turned portion 55 is inclined downward away from the brush disc holder 1. The existence of the outward-turned portion 55 makes the part of the water baffle strip 52 in contact with the outward-turned portion 55 also turn outward at a predetermined angle, so that the water-blocking portion of the water baffle strip 52 can maintain the best water scraping effect.

[0049] In this embodiment, the elastic member 3 is a tension spring. An extension portion 241 is formed at the bottom end of the second connecting rod 24. One end of the tension spring is hooked on the extension portion 241. A fixing block 56 is fixedly connected to the side of the water baffle 5 away from the water baffle strip 52. The end of the tension spring away from the extension portion 241 is hooked on the fixing block 56. Thus, the tension spring is used to pull the water baffle 5 to move away from the water baffle holder 2, providing a downward pressure for the water baffle strip 52.

[0050] A guide wheel 57 is installed on the side of the water baffle 5 close to the brush disc holder 1 and at the bending portion 54 of the water baffle 5. The guide wheel 57 can rotate relative to the water baffle 5. When the guide wheel 57 contacts the ground, the water baffle strip 52 no longer presses down. This is the maximum downward pressure of the water baffle strip 52 and also the best downward pressure angle. When the brush disc holder 1 moves backward, under the frictional force between the water baffle strip 52 and the ground, the connecting rod assembly tends to swing downward, hindering the backward movement of the brush disc holder 1. At this time, the guide wheel 57 rolls to offset the swinging trend of the connecting rod assembly, realizing smooth operation.

[0051] Refer to Figure 4 and Figure 7 , the limiting member 4 is a limiting cylinder. The limiting cylinder is arranged on the side of the water baffle holder 2 close to the brush disc holder 1, and the circumferential side of the limiting cylinder abuts against the first connecting rod 23 to limit the first connecting rod 23, thereby limiting the swinging range of the water baffle strip 52; when the first connecting rod 23 contacts the circumferential side of the limiting cylinder, the first connecting rod 23 no longer swings downward.

[0052] Refer to Figure 7 and Figure 8 , a long slot 25 corresponding to the position of the limiting cylinder is formed on the water baffle holder 2. An adjusting component connected to the limiting cylinder is arranged in the long slot 25. The adjusting component is used to adjust the position of the limiting cylinder so as to adjust the swinging range of the connecting rod assembly.

[0053] The adjusting component includes a screw rod 41 rotatably connected in the long slot 25, an adjusting block 42 slidably connected to the long slot 25 and threadedly connected to the screw rod 41, and an adjusting member connected to the screw rod 41. An end face of the limiting cylinder is fixedly connected with a connecting shaft 43 coaxial with the limiting cylinder. The end of the connecting shaft 43 away from the limiting cylinder is fixedly connected to the adjusting block 42. Thus, by driving the screw rod 41 to rotate through the adjusting member, the adjusting block 42 drives the limiting cylinder to slide along the length direction of the long slot 25, changing the abutting position between the first connecting rod 23 and the limiting cylinder, and further adjusting the swinging range of the connecting rod assembly.

[0054] Reference Figure 7 and Figure 8 The adjusting member includes a bracket 44 fixedly connected to the side of the water retaining frame 2 away from the limiting cylinder, a worm 45 rotatably connected to the bracket 44, a worm wheel 46 fixedly sleeved on the circumference of the screw 41 and meshing with the worm 45, a cylinder 47 fixedly connected to the end of the worm 45 away from the worm wheel 46, and a rotating disk 48 fixedly connected to the end of the cylinder 47 away from the worm 45. By rotating the rotating disk 48, the worm 45 is driven to rotate, so that the rotating worm 45 drives the screw 41 to rotate through the worm wheel 46.

[0055] Reference Figure 8 and Figure 9 A groove 441 and a slide groove 442 are provided on the top surface of the bracket 44, and an abutment shaft 443 is vertically slidable in the slide groove 442, and a first spring 444 is fixedly connected between the inner bottom wall of the slide groove 442 and the bottom end of the abutment shaft 443; an extension block 445 extending to the outside of the groove 441 is rotatably connected in the groove 441, and a toggle plate 446 is fixedly connected to the top of the extension block 445, and a pressing portion 447 bent upward is formed on the end of the toggle plate 446 close to the abutment shaft 443, and the top of the abutment shaft 443 abuts against the pressing portion 447, and the toggle plate 446 is rotated. A receiving groove 448 is provided at one end of 46 away from the pressing portion 447, in which a stopper 4481 is slidably connected, and a second spring 4482 is fixedly connected between the stopper 4481 and the receiving groove 448; a clamping portion 4483 is formed on the bottom surface of the stopper 4481 and at one end of the stopper 4481 extending outside the receiving groove 448, and a plurality of clamping grooves 449 equidistantly distributed in the circumferential direction of the circle are provided on the circumferential side of the cylinder 47, and the clamping portion 4483 is clamped in the clamping groove 449 corresponding in position to limit the rotation of the turntable 48.

[0056] Thus, the pressing portion 447 is pressed downward to disengage the engaging portion 4483 from the engaging groove 449. At this time, the adjusting block 42 can be moved in the elongated opening 25 by rotating the rotary disk 48 to adjust the position of the limiting cylinder. After the position of the limiting cylinder is adjusted, the pressing portion 447 can be released, the first spring 444 is reset, and the top end of the abutting shaft 443 lifts the pressing portion 447, so that the engaging portion 4483 is engaged with the engaging groove 449 corresponding to the position, thereby limiting the rotation of the rotary disk 48.

[0057] Reference Figure 7 and Figure 9, the two adjacent clamping grooves 449 are staggered to minimize the distance between the two adjacent clamping grooves 449, which is conducive to the clamping of the clamping part 4483 with the corresponding clamping groove 449; and the second spring 4482 and the accommodating groove 448 are set so that the stopper 4481 can be extended and retracted relative to the toggle plate 446, which is conducive to the clamping of the clamping part 4483 with the corresponding clamping groove 449. At the same time, in order to protect the adjustment component, the side of the water retaining frame 2 away from the limit cylinder is detachably connected to a protective shell (not shown in the figure) through a fastening bolt, and the long strip 25, the rotating disk 48 and the bracket 44 are all located in the protective shell.

[0058] The implementation principle of a lifting water retaining system in an embodiment of the present application is as follows: the water retaining assembly, the connecting rod assembly and the water retaining frame 2 form a parallelogram structure, so that the connecting rod assembly can drive the water retaining assembly to swing in a direction close to or away from the water retaining frame 2, thereby realizing the position adjustment function of the water retaining assembly; the elastic member 3 pulls the water retaining assembly to move in a direction away from the water retaining frame 2, providing a stable downward pressure for the water retaining assembly, and ensuring the contact effect between the water retaining assembly and the ground; the limit member 4 limits the swing range of the connecting rod assembly, effectively reducing the structural failure caused by excessive swinging of the water retaining assembly; the water retaining part of the water retaining assembly is turned outward at a predetermined angle, which improves the scraping effect, reduces the risk of the water retaining part being rolled under the scrubbing brush 121, and improves the sewage collection efficiency and cleaning effect as a whole.

[0059] An embodiment of the present application also discloses a floor scrubber using a lifting water retaining system, including a floor scrubber body and a squeegee arranged on the bottom surface of the floor scrubber body and located on the rear side of the floor scrubber body, the squeegee being used to collect sewage behind the front water retaining assembly, that is: the squeegee is located at one end of the water retaining plate 5 away from the plug-in portion 53; the brush plate frame 1 is installed on the bottom surface of the floor scrubber body through a lifting mechanism.

[0060] The lifting function of the brush plate frame 1 is realized by the lifting mechanism, and the scrubbing brush 121 rises and falls with the brush plate frame 1. The water retaining frame 2 is connected to the brush plate frame 1 by the hinge 21 and the buckle 22. The water retaining plate 5 is connected to the water retaining frame 2 by the connecting rod assembly to form a parallelogram structure. The tension spring provides a stable downward force, the guide wheel 57 limits the maximum downward pressure of the water retaining strip 52, and the limiter 4 limits the swing range of the connecting rod assembly. The prefabricated outward turning angle of the water retaining plate 5 improves the wiping effect and effectively reduces the water retaining strip 52 from being drawn under the scrubbing brush 121. The overall structure can automatically adapt to the wear of the scrubbing brush 121, maintain the best wiping effect, and operate stably under various working conditions, thereby improving the sewage collection efficiency and cleaning effect.

[0061] The above are all preferred embodiments of the present application, and the protection scope of the present application is not limited thereto. Therefore, any equivalent changes made according to the structure, shape, and principle of the present application should be included in the protection scope of the present application.
