Description

Technical Field

[0002] Cleaning equipment such as vacuum cleaners and floor scrubbers are usually equipped with a squeegee mechanism. During the cleaning process, the squeegee mechanism contacts the ground, forming a vacuum space. As the cleaning equipment moves, it absorbs water or other liquids on the ground to keep the ground dry and clean.

Some squeegee mechanisms employ complex adjustment mechanisms to adjust the angle, making assembly and adjustment complex. Others adjust the angle by adding or removing spacers, requiring repeated attempts and a complex adjustment process. Utility Model Content

[0034] The following will be combined with the drawings in the embodiments of this application to clearly and completely describe the technical solutions in the embodiments of this application. Obviously, the embodiments described are only part of the embodiments of this application, not all of the embodiments. Based on the embodiments in this application, all other embodiments obtained by ordinary technicians in this field based on this application are within the scope of protection of this application.

[0035] As mentioned in the background art, cleaning equipment such as vacuum cleaners and floor scrubbers are usually equipped with a squeegee mechanism. During the cleaning process, the squeegee mechanism contacts the ground, forming a vacuum space. As the cleaning equipment moves, it absorbs water or other liquids on the ground to keep the ground dry and clean.

[0036] When the squeegee mechanism is at an angle to the floor, meaning it's not firmly attached to the floor, it can lead to poor water absorption and, consequently, poor cleaning results. Some squeegee mechanisms employ complex adjustment mechanisms to adjust the angle, making assembly and adjustment complex. Others adjust the angle by adding or removing spacers, requiring repeated attempts and a complex adjustment process.

[0037] In order to facilitate adjustment of the contact angle between the squeegee mechanism and the ground, an embodiment of the present application provides a squeegee mechanism and a cleaning device. Specifically, the cleaning device includes a vehicle body and a squeegee mechanism. The squeegee mechanism provided in the embodiment of the present application is described in detail below.

[0038] See also Figure 1 and Figure 2 , Figure 1 A three-dimensional structural diagram of the squeegee mechanism according to an embodiment of the present application from a first angle; Figure 2 for Figure 1 The exploded diagram of the squeegee mechanism (not shown is the electric push rod mechanism and the squeegee body). Figure 1 and Figure 2 As shown, the squeegee mechanism is arranged at the bottom of the vehicle body, and includes: a fixing frame 100, a pitch adjustment structure 200, a squeegee mounting seat 300 and a squeegee body 400.

[0039] The top of the fixing frame 100 is used for fixed connection with the vehicle body. The squeegee body 400 is used for contacting the ground and is fixedly arranged at the bottom of the squeegee mounting seat 300.

[0040] The pitch adjustment structure 200 is disposed between the squeegee mounting seat 300 and the fixing frame 100 , is fixedly connected to the squeegee mounting seat 300 , and is rotatably connected to the fixing frame 100 .

[0041] The pitch adjustment structure 200 includes an operating handle 210 , which is used to adjust the pitch angle of the squeegee mounting seat 300 relative to the fixing frame 100 , so as to adjust the angle between the squeegee body 400 and the ground.

[0042] In the squeegee mechanism provided in this embodiment, the pitch adjustment structure 200 is disposed between the squeegee mounting base 300 and the fixed frame 100. It is fixedly connected to the squeegee mounting base 300 and rotatably connected to the fixed frame 100. The operating handle 210 of the pitch adjustment structure 200 can adjust the pitch angle of the squeegee mounting base 300 relative to the fixed frame 100, thereby adjusting the angle between the squeegee body 400 and the ground surface, ensuring a close contact between the squeegee body 400 and the ground surface and ensuring effective water absorption. This pitch adjustment structure, which allows the angle of the squeegee body 400 to be adjusted simply by adjusting the operating handle, is much simpler and more convenient than existing techniques.

[0043] In some embodiments of the present application, Figure 1 and Figure 2 As shown, the squeegee mechanism further includes: a lifting and adjusting structure 500 ; the fixing frame 100 includes: a first fixing frame 110 and a second fixing frame 120 .

[0044] The top of the first fixing frame 110 is fixedly connected to the vehicle body; the bottom is movably connected to the second fixing frame 120; the squeegee body 400 is rotatably connected to the second fixing frame 120 through the pitch adjustment structure 200.

[0045] One end of the lifting adjustment structure 500 is fixed to the vehicle body, and the other end is fixedly connected to the second fixing frame 120, which can drive the second fixing frame 120 to rotate relative to the first fixing frame 110, so that the second fixing frame 120 drives the squeegee body 400 to rise and fall relative to the ground.

[0046] Specifically, the squeegee mechanism is arranged at the bottom of the vehicle body, and the lifting and adjusting structure 500 is applied to drive the squeegee body 400 to descend when the ground needs to be cleaned so as to fit the ground and absorb water; when it is not needed to work, the squeegee body 400 is driven to rise, which can avoid the squeegee body 400 from always contacting the ground, reduce wear and tear, and extend the service life of the squeegee body 400.

[0047] By applying the embodiment of the present application, the squeegee mechanism 400 has the functions of adjustable lifting and pitch angle adjustment. Under the action of the pitch adjustment structure 200, the pitch angle of the squeegee mounting base 300 relative to the fixing frame 100 can be adjusted to make the squeegee body 400 fit closely with the ground to ensure the water absorption effect; and under the action of the lifting adjustment structure 500, the lifting of the squeegee body 400 relative to the ground can be adjusted to extend the service life of the squeegee body 400.

[0048] In some embodiments of this application, see Figures 3 to 5 , Figure 3 for Figure 1 A three-dimensional structural diagram of the squeegee mechanism from a second angle; Figure 4 for Figure 3A three-dimensional structural diagram of the squeegee mechanism from a side view; Figure 5 for Figure 3 A three-dimensional structural diagram of the squeegee mechanism shown from an upward angle.

[0049] like Figures 1 to 3 As shown, a link mechanism 130 is provided on both sides of the first fixing frame 110 and the second fixing frame 120 , and both ends of the link mechanism 130 are hinged to the first fixing frame 110 and the second fixing frame 120 respectively.

[0050] Driven by the lifting adjustment structure 500 , the second fixing frame 120 can rotate relative to the first fixing frame 110 based on the connecting rod mechanism 130 to achieve lifting.

[0051] Specifically, the linkage mechanism includes a plurality of parallel connecting rods 131, each of which is hingedly connected to the first and second fixing frames 110, 120 at both ends via hinge pins. In the specific embodiment of the present application, two parallel connecting rods 131 are provided on either side of the first and second fixing frames 110, 120. These two connecting rods 131 and their hinge pins at both ends form a stable parallelogram linkage structure, enabling the second fixing frame 120 to be stably raised and lowered along with the linkage mechanism 130.

[0052] When the lifting adjustment structure 500 drives the second fixing frame 120 to rise, the second fixing frame 120 rotates clockwise relative to the first fixing frame 110 along with the connecting rod 131 to above the first fixing frame 110, thereby achieving the ascent of the second fixing frame 120. Conversely, when the lifting adjustment structure 500 drives the second fixing frame 120 to descend, the second fixing frame 120 rotates counterclockwise relative to the first fixing frame 110 along with the connecting rod 131 to below the first fixing frame 110, thereby achieving the descent of the second fixing frame 120.

[0053] In this embodiment of the present application, the linkage mechanism 130 is provided to define the range of movement of the second mounting frame 120 driven by the lifting adjustment structure 500. The second mounting frame 120 rotates clockwise or counterclockwise relative to the first mounting frame 110 along with the linkage mechanism 130 to a position above or below the first mounting frame 110, thereby achieving the lifting and lowering of the second mounting frame 120, and thus the lifting and lowering of the squeegee body 400. Furthermore, the linkage mechanism 130 has a simple structure, simplifying the assembly process of the squeegee mechanism.

[0054] In some embodiments of the present application, Figure 1 and Figure 2 As shown, the lifting and adjusting structure 500 includes: an electric push rod mechanism 510, a roller assembly 520 and a traction rope 530.

[0055] like Figure 1 、 Figure 2 、 Figure 6 and Figure 7 As shown, Figure 6 for Figure 1 The three-dimensional structural diagram of the electric linear actuator shown; Figure 7 for Figure 1 The three-dimensional structure diagram of the roller assembly is shown. The electric push rod mechanism 510 is fixedly connected to the vehicle body; the roller assembly 520 includes a wheel frame 521 and a roller 522; the wheel frame 521 is fixedly connected to the vehicle body, and the roller 522 is rotatably mounted on the wheel frame 521.

[0056] One end of the traction rope 530 is fixedly connected to the telescopic end 510 a of the electric push rod mechanism 510 , and the other end is fixedly connected to the second fixing frame 120 after passing around the roller 522 .

[0057] The electric push rod mechanism 510 can extend and retract the traction rope 530 to drive the second fixing frame 120 to rotate relative to the first fixing frame 110 based on the connecting rod mechanism 130, so that the second fixing frame 120 drives the squeegee body 400 to rise and fall relative to the ground.

[0058] Specifically, if Figure 1 and Figure 6 As shown, the electric push rod mechanism 510 includes a motor 511 and a push rod 512, and the head of the push rod 512 is a push rod telescopic end 510a. The housings of the motor 511 and the push rod 512 are fixedly connected and fixed to the vehicle body through the electric push rod mounting base 513. The specific connection method is not limited in this application, and can be connected by threaded fasteners or as shown in FIG. Figure 6 As shown, the bottom of the push rod 512 is fixedly connected to the electric push rod mounting seat 513 through the cooperation of the perforated pin and the pin shaft.

[0059] The arrangement direction of the electric push rod mechanism 510 is not limited in this application and can be arranged horizontally, tilted or vertically. As long as the section of the traction rope 530 between the roller 522 and the second fixing member 120 is vertical or tilted at a certain angle, the second fixing frame 120 can be pulled up and down. In the specific embodiment of this application, if Figure 1 As shown, the electric push rod mechanism 510 is arranged horizontally, and the push rod telescopic end 510a can telescope and pull the traction rope 530 in the horizontal direction, so that the traction rope 530 section located between the roller 522 and the second fixing member 120 can vertically pull the second fixing frame 120.

[0060] like Figure 7As shown, the wheel frame 521 of the roller assembly 520 includes two roller support plates 521a arranged opposite and spaced apart. The roller 522 is disposed between the two roller support plates 521a and is rotatably connected to the two roller support plates 521a via a roller shaft 523. The roller 522 can be hollow, with its hollow portion forming a concentric circle with the outer circumference of the roller 522. The hollow portion is provided with a bearing secured by a retaining spring. The outer ring of the bearing is tightly fitted with the roller 522, and the inner ring is tightly fitted with the roller shaft 523. This allows the roller 522 to rotate relative to the roller shaft 523 based on the rotation between the outer and inner rings of the bearing.

[0061] The type of traction rope 530 is not limited in this application. It can be a nylon rope or steel wire rope, which is flexible, corrosion-resistant, and not easily aged. Alternatively, it can be a chain, which has a strong load-bearing capacity. A corresponding sprocket should be selected for the roller 522. The traction rope 530 can be wrapped around the roller 522 multiple times, or it can simply pass around the roller 522 to be fixedly connected to the second fixing frame 120. The specific length of the traction rope 530 can be selected based on the lifting range of the second fixing frame 120 and is not limited in this application.

[0062] The specific connection method between the traction rope 530 and the second fixing frame 120 is not limited in this application. The traction rope 530 can be directly tied to the second fixing frame 120 or connected to the second fixing frame 120. Figure 3 and Figure 4 As shown, the end of the traction rope 530 is sleeved on the first traction rope mounting pin 531, and the second traction rope mounting pin 532 with an opening at the end is fixedly provided on the second fixing frame 120. The first traction rope mounting pin 531 and the opening on the second traction rope mounting pin 532 are tightly matched to fix the traction rope 530. The tightness of the traction rope 530 can be adjusted by adjusting the length of the second traction rope mounting pin 532 extending out of the second fixing frame 120.

[0063] In this embodiment of the present application, an electric push rod mechanism 510 is provided to retractably pull a traction rope 530, thereby driving the second mounting frame 120 to rotate relative to the first mounting frame 110 via the linkage mechanism 130. This allows the second mounting frame 120 to drive the squeegee body 400 to rise and fall relative to the ground. Furthermore, the lifting and lowering mechanism 500, comprising the electric push rod mechanism 510, the roller assembly 520, and the traction rope 530, offers a simple structure and easy installation, simplifying the assembly process of the squeegee mechanism.

[0064] In some embodiments of the present application, Figures 3 to 5 As shown, the first fixing frame 110 includes: two first side plates 111 arranged opposite to each other; the two first side plates 111 are fixedly connected by a connecting rib 112; and the electric push rod mechanism 510 is located between the two first side plates 111.

[0065] The second fixing frame 120 includes two second side plates 121 opposite to each other. The two second side plates 121 are fixedly connected via a second handle mounting plate 122 . The second handle mounting plate 122 is provided with an accommodating hole 1221 .

[0066] One end of the operating handle 210 of the pitch adjustment structure 200 passes through the receiving hole 1221 and is pivotally connected to the side of the second handle mounting plate 122 away from the pitch adjustment structure 200. The other end of the operating handle 210, the operating end, faces the receiving hole 1221 and is used to adjust the pitch angle of the squeegee mounting base 300 relative to the second fixing bracket 120, thereby adjusting the angle between the squeegee body 400 and the ground.

[0067] Specifically, if Figure 3 As shown, the pitch adjustment structure 200 also includes a pitch seat 220, which is fixedly connected to the top of the squeegee mounting seat 300 and rotatably connected to the fixing frame 100; the second handle mounting plate 122 is arranged opposite the pitch seat 220 and is rotatably connected at the bottom. The second traction rope mounting pin 532 is set on the second handle mounting plate 122, above the receiving hole 1221. The operating handle 210 passes through the pitch seat 220 and is inserted into the receiving hole 1221 on the second handle mounting plate 122. The operator can manually adjust the operating end of the operating handle 210 so that the pitch seat 220 drives the squeegee body 400 to rotate relative to the second handle mounting plate 122 along with the operating handle 210. The specific rotational connection method between the operating handle 210 and the second handle mounting plate 122 is detailed in the subsequent description.

[0068] The first side plate 111 and the connecting rib plate 112 can be connected into one part by welding; the second side plate 121 and the second handle mounting plate 122 can be connected into one part by welding.

[0069] By applying the embodiment of the present application, by adjusting the operating end of the operating handle 210, the pitch seat 220, the squeegee mounting seat 300 and the squeegee body 400 can be driven to rotate relative to the second handle mounting plate 122 along with the operating handle 210 to adjust the angle between the squeegee body 400 and the ground, so that the squeegee body 400 fits tightly against the ground and ensures the water absorption effect.

[0070] In some embodiments of the present application, Figures 1 to 4 As shown, the pitch seat 220 includes a connecting plate 221 and a first handle mounting plate 222; the connecting plate 221 is fixedly connected to the top of the squeegee mounting seat 300 and is rotatably connected to the fixing frame 100; the first handle mounting plate 222 is fixed to the top of the connecting plate 221, opposite to the fixing frame 100 and spaced apart.

[0071] The operating handle 210 is set on the first handle mounting plate 222, and can adjust the distance between the first handle mounting plate 222 and the fixing frame 100, so that the pitch seat 220 drives the squeegee mounting seat 300 to rotate relative to the fixing frame 100 to adjust the angle between the squeegee body 400 and the ground.

[0072] Specifically, the first handle mounting plate 222 is spaced apart from the second handle mounting plate 122. The operating handle 210 passes through the first handle mounting plate 222 and is inserted into the receiving hole 1221 on the second handle mounting plate 122. Both sides of the connecting plate 221 are rotatably connected to the second handle mounting plate 122 via pitch pins 223. The connecting plate 221 and the first handle mounting plate 222 can be welded together to form a single component.

[0073] By using the embodiment of the present application, the operator can manually adjust the operating end of the operating handle 210 so that the pitch seat 220 drives the squeegee body 400 to follow the operating handle 210 and rotate relative to the second handle mounting plate 122 .

[0074] In some embodiments of the present application, Figure 3 As shown, the operating handle 210 includes a first elastic member 211 and an adjustment limit member 212 .

[0075] The first elastic member 211 is arranged in the gap between the first handle mounting plate 222 and the fixing frame 100, one end of which is rotatably connected to the fixing frame 100, and the other end abuts against a surface of the first handle mounting plate 222 close to the fixing frame 100, and can be flipped relative to the fixing frame 100 together with the first handle mounting plate 222.

[0076] The adjustment limiter 212 is provided on the first handle mounting plate 222 and can adjust the first handle mounting plate 222 to rotate toward or away from the fixing frame 100 to adjust the compression degree of the first elastic member 211 and maintain the first handle mounting plate 222 in the adjusted position.

[0077] Specifically, the adjustment stop 212 on the first handle mounting plate 222 serves as the operating end of the operating handle 210. When the operator operates the adjustment stop 212, causing the first handle mounting plate 222 to rotate toward the mounting frame 100 based on its rotational connection with the mounting frame 100, the first elastic member 211 is compressed and rotates based on its rotational connection with the mounting frame 100. The first handle mounting plate 222 drives the squeegee mounting base 300 and the squeegee body 400 to rotate toward the mounting frame 100, causing the squeegee body 400 to rotate upward at a certain angle relative to the ground surface to conform to the convex slope of the ground.

[0078] On the contrary, when the handle 222 is rotated away from the fixing frame 100, the degree of compression on the first elastic member 211 is reduced. As the rotational connection with the fixing frame 100 rotates toward the ground, the first handle mounting plate 222 drives the squeegee mounting base 300 and the squeegee body 400 to rotate toward the ground, causing the squeegee body 400 to rotate downward at a certain angle relative to the ground to fit the ground with a concave slope.

[0079] During the above adjustment process, the first elastic member 211 and the adjustment limit member 212 apply forces in opposite directions toward the first handle mounting plate 222 , so that the first handle mounting plate 222 can be maintained at the adjusted position.

[0080] By applying the embodiment of the present application, by providing the first elastic member 211 and the adjustment limit member 212, the pitch adjustment structure 200 is simple in structure and easy to assemble. The angle between the squeegee body 400 and the ground can be adjusted by manually operating the adjustment limit member 212. The adjustment method is simpler than the existing technology.

[0081] In some embodiments of the present application, Figure 3 and Figure 4 As shown, the first elastic member 211 is a spring, and the adjustment limit member 212 includes a pin rod 2121 and a hand-tightening nut 2122 .

[0082] One end of the pin rod 2121 is rotatably connected to the fixing frame 100 , and the other end passes through the first handle mounting plate 222 and is threadedly connected to a hand nut 2122 provided on a side of the first handle mounting plate 222 away from the fixing frame 100 .

[0083] The first elastic member 211 is sleeved on the section of the pin rod 2121 located between the first handle mounting plate 222 and the fixing frame 100; rotating the hand nut 2122 can adjust the first handle mounting plate 222 to rotate toward or away from the fixing frame 100 to adjust the angle between the squeegee body 400 and the ground.

[0084] Specifically, in other embodiments of the present application, the accommodating hole 1221 and the compression spring seat 1222 may not be provided on the second handle mounting plate 122 , and the end of the pin rod 2121 is directly rotatably connected to the surface of the second handle mounting plate 122 .

[0085] like Figure 5As shown, in a specific embodiment of the present application, a raised compression spring seat 1222 is provided on a side of the second handle mounting plate 122 away from the pitch seat 220, surrounding a receiving hole 1221. An opening is provided on one end of the pin 2121 that passes through the receiving hole 1221. A compression spring pin 1223 passes through the compression spring seat 1222 and the opening at the end of the pin 2121, thereby rotatably connecting the pin 2121 to the compression spring seat 1222 on the second handle mounting plate 122. The provision of the receiving hole 1221, the compression spring seat 1222, and the compression spring pin 1223 allows a portion of the pin 2121 and the first elastic member 211 mounted on the pin 2121 to pass through the receiving hole 1221 and be located on the side of the second handle mounting plate 122 away from the pitch seat 220. This improves the space utilization of the pitch adjustment structure 200. Furthermore, the receiving hole 1221 also limits the rotation range of the operating handle 210, preventing damage to the squeegee body 400 due to excessive rotation.

[0086] The outer surface of one end of the pin 2121, which is connected to the hand nut 2122, is provided with threads, which are connected to the internal threads of the hand nut 2122. Rotating the hand nut 2122 can adjust the length of the portion of the pin 2121 that is threadedly connected to the hand nut 2122, thereby adjusting the distance between the first handle mounting plate 222 and the second handle mounting plate 122, and thus adjusting the angle between the squeegee body 400 and the ground.

[0087] The specific type of the hand-tightening nut 2122 is not limited in this application, and can be Figures 1 to 4 Provided plum blossom nuts, butterfly nuts, etc. When the operator tightens the hand nut 2122, the hand nut 2122 applies a force toward the second handle mounting plate 122 on the first handle mounting plate 222, causing the first handle mounting plate 222 to rotate toward the second handle mounting plate 122 and squeeze the first elastic member 211. The first elastic member 211 rotates with the first handle mounting plate 222 and applies a reverse force to the first handle mounting plate 222, allowing the first handle mounting plate 222 to maintain its adjusted position. Conversely, when the hand nut 2122 is loosened, the first elastic member 211 extends, applying a force to the first handle mounting plate 222 that is directed away from the second handle mounting plate 122. The hand nut 2122 applies a force in the reverse direction to the first handle mounting plate 222, allowing the first handle mounting plate 222 to maintain its adjusted position.

[0088] In the embodiment of the present application, the adjustment limit member 212 includes a pin rod 2121 and a hand nut 2122, which has a simple structure, making the pitch adjustment structure 200 easy to assemble, and the angle between the squeegee body 400 and the ground can be adjusted by manually rotating the hand nut 2122. The adjustment method is simpler than the existing technology.

[0089] In some embodiments of the present application, Figures 1 to 4As shown, the squeegee mechanism further includes a horizontal adjustment structure 600 ; the horizontal adjustment structure 600 includes two second elastic members 610 .

[0090] The two second elastic members 610 are disposed on the squeegee mounting base 300 and are located on both sides of the pitch base 220 .

[0091] One end of the second elastic member 610 is connected to the fixing frame 100, and the other end is connected to the squeegee mounting base 300, so as to drive the squeegee mounting base 300 and the squeegee body 400 to reset when the squeegee mounting base 300 and the squeegee body 400 deviate relative to the fixing frame 100.

[0092] Specifically, the squeegee mechanism provided in the embodiment of the present application, the first fixing frame 110, the second fixing frame 120, the operating handle 210, the pitch seat 220, the squeegee mounting seat 300 and the squeegee body 400 are connected from high to low and are symmetrical on both sides. The operating handle 210 and the pitch seat 220 are located on the central axis, and the two second elastic members 610 are symmetrically distributed on both sides of the pitch seat 220, so that the weight on the squeegee mounting seat 300 is evenly distributed, avoiding the different heights of the two ends of the squeegee body and the different pressures generated by the contact with the ground, which aggravates the damage to the lower end.

[0093] When the vehicle turns the squeegee mechanism or the squeegee mechanism hits an obstacle, the squeegee mount 300 and squeegee body 400 shift horizontally relative to the mounting bracket 100. This causes the second elastic member 610 on one side to stretch and the second elastic member 610 on the other side to compress. The stretched second elastic member 610 exerts a pulling force on the squeegee mount 300 toward its original position, while the compressed second elastic member 610 pushes the squeegee mount 300 toward its original position, thereby returning the shifted squeegee mount 300 and squeegee body 400 to their original position.

[0094] By using the embodiment of the present application, when the squeegee mounting base 300 and the squeegee body 400 are offset relative to the fixing frame, the second elastic member 610 can play a role in adjusting and resetting, applying a force to the offset squeegee mounting base 300 and the squeegee body 400 to reset them, and also plays a buffering role to prevent the squeegee body 400 from being damaged, thereby extending the service life of the squeegee body 400.

[0095] In some embodiments of the present application, Figure 3 and Figure 4 As shown, the second elastic member 610 is a spring, and the second elastic member 610 is connected to the squeegee mounting seat 300 via a tension spring pin 620 and a tension spring seat 630 .

[0096] The tension spring seat 630 is fixedly set on the top of the squeegee mounting seat 300; one end of the tension spring pin 620 is fixedly connected to the end of the second elastic member 610, and the other end passes through the tension spring seat 630 and is threadedly connected to the adjusting nut 640 set on the side of the tension spring seat 630 away from the second elastic member 610.

[0097] The adjusting nut 640 adjusts the deformation degree of the second elastic member 610 by adjusting the length of the tension spring pin 620 extending from the adjusting nut 640 .

[0098] Specifically, based on the tension spring pin 620 , the tension spring seat 630 and the adjustment nut 640 , the second elastic member 610 and the squeegee mounting base 300 are adjustable.

[0099] Adjusting the deformation of the second elastic member 610 adjusts the stiffness of the second elastic member 610, thereby adjusting the ability of the squeegee body 400 to resist deformation. Specifically, by adjusting the second elastic member 610, the stiffness of the entire squeegee mechanism can be adjusted to suit different floor conditions. For rougher floors, the stiffness of the second elastic member 610 can be increased, while for smoother floors, the stiffness can be appropriately reduced.

[0100] The adjusting nuts 640 can also be configured as hand-tight nuts to facilitate rotation by the operator. When the operator tightens the adjusting nuts 640 at both ends of the squeegee mount 300, a larger portion of the end of the tension spring pin 620 moves to the side of the adjusting nut 640 away from the tension spring seat 630. The second elastic member 610 exerts a greater pulling force on the squeegee mount 300 through the tension spring seat 630, thereby increasing the overall stiffness of the squeegee mechanism. Conversely, when the operator loosens the adjusting nuts 640 at both ends of the squeegee mount 300, a portion of the tension spring pin 620 located on the side of the adjusting nut 640 away from the tension spring seat 630 moves to the side of the tension spring seat 630 closer to the fixing bracket 100. The pulling force of the second elastic member 610 on the squeegee mount 300 is reduced, thereby reducing the overall stiffness of the squeegee mechanism.

[0101] In this embodiment, the second elastic member 610 is connected to the squeegee mounting base 300 via a tension spring pin 620 and a tension spring base 630, resulting in a simple structure and easy assembly. The stiffness of the squeegee mechanism can be adjusted simply by rotating the adjustment nut 640, making adjustment of the squeegee mechanism's stiffness even simpler.

[0102] In some embodiments of the present application, Figure 2 As shown, two left and right adjustment holes 310 are provided on the squeegee mounting seat 300 , and the two left and right adjustment holes 310 are arranged in a direction perpendicular to the first handle mounting plate 222 .

[0103] The connecting plate 221 of the pitch seat 220 is connected to the two left and right adjustment holes 310 via bolts 320 ; the left and right adjustment holes 310 close to the first handle mounting plate 222 are larger than the diameter of the bolts 320 .

[0104] Specifically, if Figure 2 As shown, in a specific embodiment of the present application, the two left and right adjustment holes 310 on the squeegee mounting seat 300 are spaced apart.

[0105] The lateral dimensions of the left and right adjustment holes 310 near the first handle mounting plate 222 are larger than the diameter of the bolt 320 and can be an elliptical hole, a waist-shaped hole or an arc-shaped hole, leaving space margin for the squeegee mounting seat 300 and the squeegee body, and also leaving space margin for the adjustment and reset of the second elastic member 610.

[0106] The squeegee mounting seat 300 can use the bolt set at the left and right adjustment holes 310 away from the first handle mounting plate 222 as the rotation axis. Relative to the rotation of the pitch seat 220, the rotation stroke is the horizontal length of the left and right adjustment holes 310 close to the first handle mounting plate 222.

[0107] That is, when the squeegee mechanism turns or touches an obstacle, the squeegee mounting seat 300 and the squeegee body 400 can rotate with the left and right adjustment holes 310 away from the first handle mounting plate 222 as the rotation center, and the rotation will be offset. The second elastic member 610 that is deformed due to the offset can drive the offset squeegee mounting seat 300 and the squeegee body 400 to adjust and reset based on the left and right adjustment holes 310.

[0108] A gasket 330 is provided between the bolt 320 and the connecting plate 221 and is made of copper to reduce friction between the bolt 320 and the connecting plate 221 .

[0109] By applying the embodiment of the present application, when the squeegee mechanism turns or touches an obstacle, the squeegee mounting base 300 can drive the squeegee body 400 to move based on the space margin left by the left and right adjustment holes 310 near the first handle mounting plate 222, and the second elastic member 610 can also adjust and reset the squeegee mounting base 300 and the squeegee body 400 based on the space margin.

[0110] The cleaning device provided in the embodiment of the present application includes the squeegee mechanism and the vehicle body described in any of the above embodiments; the vehicle body can drive the squeegee mechanism to move on the ground.

[0111] Specifically, if Figure 1 and Figure 2As shown, a water-absorbing rubber strip is provided at the bottom of the squeegee body 400 for fitting with the ground to form a sealed space to collect sewage; a sewage outlet 410 is provided at the top for connecting to a sewage pipe to transport the collected sewage to the sewage tank on the vehicle body.

[0112] Anti-collision turntables 420 are also rotatably provided at the top of both ends of the squeegee body 400. The diameter of the anti-collision turntables 420 is larger than the end size of the squeegee body 400, so that when the vehicle body drives the squeegee body 400 to move, it will collide with obstacles before other parts, thereby protecting the squeegee body 400.

[0113] The squeegee body 400 is further provided with two travel wheel assemblies 430 , each travel wheel assembly 430 includes two universal wheels 431 , one front and one rear, arranged on both sides of the squeegee body 400 , which can support the squeegee body 400 and roll on the ground as the vehicle body moves.

[0114] The two traveling wheel groups 430 can be Figure 1 As shown, the squeegee body 400 is symmetrically arranged at the left and right ends to keep the squeegee body 400 balanced.

[0115] In the cleaning device provided in the embodiments of the present application, the pitch adjustment structure 200 of the squeegee mechanism is disposed between the squeegee mounting base 300 and the fixed frame 100. It is fixedly connected to the squeegee mounting base 300 and rotationally connected to the fixed frame 100. The operating handle 210 of the pitch adjustment structure 200 can adjust the pitch angle of the squeegee mounting base 300 relative to the fixed frame 100, thereby adjusting the angle between the squeegee body 400 and the ground surface, ensuring a close contact between the squeegee body 400 and the ground surface and ensuring effective water absorption. Compared to existing technologies, this pitch adjustment structure, which allows the angle of the squeegee body 400 to be adjusted simply by adjusting the operating handle, makes the adjustment process simpler and more convenient.
