[0002] As people's living standards improve, cleaning equipment has gradually entered households and become a small helper for household cleaning. Among them, some cleaning equipment (such as cleaning robots, floor scrubbers, etc.) are equipped with a wiper mechanism, which is pressed against a cleaning module (such as a roller brush or a crawler mop). While the cleaning equipment is mopping the floor, the dirt on the cleaning module is scraped off by the wiper mechanism and collected in a sewage tank, so that a relatively clean mop or roller brush is always used to clean the floor, which has a better cleaning effect and is widely loved by users.

[0003] However, the wiper mechanisms of existing cleaning devices are all mounted and fixed on the machine body, which is inconvenient for users to clean the wiper mechanisms.

[0004] After being used for a long time, some positions on the surface of the cleaning module may become dented, and there will be a gap between the dented position and the wiper mechanism, resulting in poor contact. Therefore, during the operation of the cleaning equipment, the contact between the wiper mechanism and the cleaning module appears sometimes far and sometimes close, resulting in uneven wiping effect of the wiper mechanism on different positions of the cleaning module, and then uneven water stains on the ground, affecting the cleaning effect.

Therefore, the features defined as "first" and "second" may explicitly or implicitly include at least one of the features. In addition, the technical solutions between the various embodiments can be combined with each other, but they must be based on the ability of ordinary technicians in this field to implement them. When the combination of technical solutions is contradictory or cannot be implemented, it should be deemed that such a combination of technical solutions does not exist and is not within the scope of protection required by the present utility model.

[0042] The utility model provides a cleaning device, which is applied to cleaning equipment (for example, a mopping robot, a sweeping and mopping robot, a handheld floor scrubber, etc.).

[0043] Reference Figure 1 and Figure 2 In this embodiment, the cleaning device includes a mounting frame 100, a cleaning module 200 (a drum or a device using a crawler mop) and a sewage tank 300. The cleaning module 200 and the sewage tank 300 are both arranged on the mounting frame 100, and the sewage tank 300 is detachably arranged on the mounting frame 100. Among them, the cleaning module 200 is used to contact the surface of an object to clean the surface of the object; a wiper mechanism 400 is arranged on the side of the sewage tank 300 close to the cleaning module 200, and the wiper mechanism 400 abuts against the cleaning module 200 to scrape off the dirt on the cleaning module 200; the sewage inlet 301 of the sewage tank 300 is docked with the wiper mechanism 400 to receive the dirt scraped from the cleaning module 200 by the wiper mechanism 400, that is, the dirt scraped by the wiper mechanism 400 directly flows from the sewage inlet 301 into the sewage tank 300 for storage. In this embodiment, the cleaning module 200 can be a drum-type cleaning member (refer to Fig.10 , for example, a roller brush), or a crawler cleaning element (reference Figure 1-Figure 3 ); wherein the crawler-type cleaning member comprises a wiper and a plurality of rotating rollers, wherein the wiper is an annular structure connected at both ends, the wiper is arranged around the plurality of rotating rollers, and the plurality of rotating rollers jointly tension the wiper; a portion of the outer surface of the wiper can contact the ground to clean the ground; and the cleaning device has a driving assembly for driving at least one rotating roller to rotate, and the rotating rotating roller drives the wiper to move around the plurality of rotating rollers through the friction between the outer surface and the wiper.

[0044] The cleaning device of the present embodiment arranges the wiper mechanism on the sewage tank 300, and the sewage tank 300 is detachably arranged on the mounting frame 100, so that the wiper mechanism 400 and the sewage tank 300 are taken and placed synchronously. When the user wants to clean the wiper mechanism 400, he only needs to remove the sewage tank 300 from the mounting frame 100, and the wiper mechanism 400 can be removed at the same time, which is convenient for the user to clean the wiper mechanism 400. After cleaning the wiper mechanism 400, he only needs to reinstall the sewage tank 300 on the mounting frame 100, that is, the reset of the wiper mechanism 400 is completed at the same time, so that the cleaning device can continue to be used normally, and the operation is convenient.

[0045] In some embodiments, the wiper mechanism 400 and the mounting frame 100 can be relatively movable, wherein the wiper mechanism 400 can be relatively movable relative to the mounting frame 100, which can be achieved by the sewage tank 300 being movably mounted on the mounting frame 100, or by the wiper mechanism 400 being movably arranged on the sewage tank 300. The cleaning device further includes an elastic mechanism, which applies an elastic force toward the cleaning module 200 to the wiper mechanism 400, so that the wiper mechanism 400 elastically abuts against the cleaning module 200. In this embodiment, the elastic mechanism can be arranged on the sewage tank 300, or on the mounting frame 100, or between the sewage tank 300 and the mounting frame 100.

[0046] Since the cleaning device applies an elastic force toward the cleaning module 200 to the wiper mechanism 400 through the elastic mechanism, the wiper mechanism 400 elastically abuts against the cleaning module 200. The elastic force of the elastic mechanism and the abutting force of the cleaning module 200 make the overall force of the wiper mechanism 400 balanced. Therefore, if the cleaning module 200 moves away from the wiper mechanism 400, the wiper mechanism 400 will lose the abutting effect of the cleaning module 200 (that is, the force of the wiper mechanism 400 is unbalanced). Since the sewage tank 300 is movably arranged on the mounting frame 100, the sewage tank 300 and the wiper mechanism 400 will move closer to the cleaning module 200 together under the elastic force applied by the elastic mechanism to the wiper mechanism 400.

[0047] When part of the surface of the cleaning module 200 is concave (i.e., the surface of the cleaning module 200 is unevenly distributed in its circumferential direction), when the concave position of the surface of the cleaning module 200 reaches the contact with the wiper mechanism 400, the supporting force of the concave position on the wiper mechanism 400 will be weakened, and the wiper mechanism 400 will be driven to move closer to the cleaning module 200 through the action of the elastic mechanism, so that the wiper mechanism 400 is pressed against the concave position on the surface of the cleaning module 200; and when the cleaning module rotates from the concave position on the surface to the non-concave position and contacts the wiper mechanism 400, the non-concave position will squeeze the wiper mechanism 400, so that the wiper mechanism 400 retreats in the direction away from the cleaning module 200; through the action of the elastic mechanism on the wiper mechanism 400, the wiper mechanism 400 is moved back and forth and adjusted according to the concave and convex surface of the cleaning device, so as to maintain stable and good contact with the surface of the cleaning device.

[0048] When the cleaning module 200 has been used for a long time, the surface of the wiping material (such as a mop) of the cleaning module 200 will be worn to varying degrees, resulting in uneven thickness of the wiping material. Some places will be thinner, and the distance between the thinner parts of the wiping material and the wiper mechanism 400 will become larger. The elastic mechanism acts on the wiper mechanism 400, which will make the wiper mechanism 400 press against the wiping material of the cleaning module 200 and maintain stable and good contact with the surface of the cleaning module 200.

[0049] The technical solution of the cleaning device of this embodiment adopts a wiper mechanism 400 that can be movably arranged relative to the mounting frame 100, and an elastic mechanism is provided to apply an elastic force to the wiper mechanism 400 toward the cleaning module 200, so that the wiper mechanism 400 elastically abuts against the cleaning module 200. In this way, even if there is a gap between a part of the cleaning module 200 and the wiper mechanism 400 (that is, a depression appears at a part of the surface of the cleaning module 200), during the operation of the cleaning device, when a gap appears between the cleaning module 200 and the wiper mechanism 400, the wiper mechanism 400 will also move toward the cleaning module 200 under the elastic force of the elastic mechanism to eliminate the gap and keep the state of being pressed against the cleaning module 200, thereby ensuring that the wiper mechanism 400 and the cleaning module 200 can always maintain good contact, thereby ensuring that the wiper mechanism 400 has a uniform wiping effect on each position of the cleaning module 200, thereby avoiding uneven water stains on the ground and improving the cleaning effect.

[0050] Reference Figure 2 and Figure 3In this embodiment, the sewage tank 300 and the cleaning module 200 are arranged side by side along the first direction F1, and the sewage tank 300 and the mounting frame 100 are slidably matched in the first direction F1, that is, the sewage tank 300 is slidably arranged on the mounting frame 100. The elastic mechanism elastically acts on the sewage tank 300 to apply an elastic force toward the cleaning module 200 to the wiper mechanism 400 through the sewage tank 300; since the wiper mechanism 400 is arranged on a side of the sewage tank 300 close to the cleaning module 200, the elastic mechanism indirectly applies the elastic force to the wiper mechanism 400 by acting on the sewage tank 300. The technical solution of this embodiment adopts a sewage tank 300 that is slidably installed on the mounting frame 100, and the sliding direction is consistent with the distribution direction of the sewage tank 300 and the cleaning module 200, so that the mounting frame 100 guides the movement of the sewage tank 300 (i.e., limits the movement along the first direction F1), and makes the movement and adjustment of the sewage tank 300 and the wiper mechanism 400 under the elastic force of the elastic mechanism more stable and accurate, thereby better ensuring that the wiper mechanism 400 maintains good contact with the surface of the cleaning module 200, ensuring uniform wiping.

[0051] Of course, in some other embodiments, the sewage tank 300 can also be arranged on the mounting frame 100 in other movable installation ways, for example, it can be suspended on the mounting frame 100 to swing toward the cleaning module 200. In some other embodiments, the elastic mechanism can also act directly on the wiper mechanism 400.

[0052] In some embodiments, the mounting frame 100 is connected to the sewage tank 300 through a sliding assembly, and the sliding assembly includes a first sliding structure 610 and a second sliding structure 620. The first sliding structure 610 is arranged on the sewage tank 300, and the second sliding structure 620 is arranged on the mounting frame 100. The first sliding structure 610 and the second sliding structure 620 are slidingly adapted in the first direction F1. Among them, the first sliding structure 610 and the second sliding structure 620 can be a slide groove and a slider 621, a sliding sleeve and a sliding rod, or a gear and a rack, etc. In this embodiment, the sewage tank 300 and the mounting frame 100 are connected by using a sliding assembly that is slidingly adapted, which further improves the sliding smoothness and stability of the sewage tank 300 relative to the mounting frame 100 in the first direction F1.

[0053] Reference Figure 1 and Figure 2In some embodiments, the mounting frame 100 includes a hanging plate 110 located above the sewage tank 300, and the sliding assembly is disposed between the hanging plate 110 and the top side of the sewage tank 300. The sewage tank 300 is slidably hung on the second sliding structure 620 through the first sliding structure 610. In this embodiment, the sewage tank 300 is slidably connected to the mounting frame 100 by assembling the hanging plate 110 hung above it. In this way, the cleaning equipment does not need to set a support structure under the sewage tank 300, which is conducive to reducing the overall height of the cleaning equipment, and the sewage tank 300 can be closer to the ground, lowering the center of gravity of the cleaning equipment, making the cleaning equipment more stable when traveling. Of course, in some other embodiments, the sewage tank 300 can also be slidably connected to the mounting frame 100 at both ends (i.e., the two ends of the sewage tank 300 in the vertical direction along the first direction F1), or the sewage tank 300 is set on the mounting frame 100 by sliding at the bottom, etc.

[0054] Reference Figures 3 to 5 In some embodiments, one of the first sliding structure 610 and the second sliding structure 620 includes at least one sliding guide groove 611 extending along the first direction F1, and the other of the first sliding structure 610 and the second sliding structure 620 includes a slider 621 corresponding to the sliding guide groove 611, and each slider 621 is slidably arranged in the corresponding sliding guide groove 611; the figure takes the first sliding structure 610 including the sliding guide groove 611 and the second sliding structure 620 including the slider 621 as an example. In addition, the figure of this embodiment takes the sewage tank 300 hanging on the hanging plate 110 of the mounting frame 100 as an example. In the illustrated structure, an anti-slip flange can be provided at the notch of the sliding guide groove 611, and the slider 621 adopts a structure with a T-shaped or L-shaped cross section, so as to prevent the slider 621 from slipping out of the notch of the sliding guide groove 611, so that the slider 621 and the sliding guide groove 611 can be slidably adapted and also achieve hanging cooperation. Of course, in some other embodiments, the sliding guide groove 611 and the sliding block 621 can be replaced with other sliding adapter components, for example, a sliding sleeve and a sliding rod.

[0055] Reference Figures 3 to 5In this embodiment, there are multiple sliding guide grooves 611 and sliders 621 (three are used as an example in the figure), and the multiple sliding guide grooves 611 are spaced apart in the vertical direction of the first direction F1. Correspondingly, the multiple sliders 621 are also spaced apart in the vertical direction of the first direction F1. Through the cooperation of multiple groups of sliding guide grooves 611 and sliders 621 spaced apart in the vertical direction of the first direction F1, the sewage tank 300 and the mounting frame 100 are slidably matched at multiple different positions, thereby improving the stability of the sliding connection between the sewage tank 300 and the mounting frame 100, and the reliability of the mounting frame 100 hanging the sewage tank 300. Among them, multiple sliding guide grooves 611 can be aligned in the vertical direction along the first direction F1, or can be misaligned; the figure of this embodiment adopts a solution of three sliding guide grooves 611, and the three sliding guide grooves 611 are misaligned, and the middle sliding guide groove 611 deviates from the connecting line of the sliding guide grooves 611 at both ends, so that the three sliding guide grooves 611 form a triangular distribution, that is, the sewage tank 300 and the mounting frame 100 are hung at three positions of the triangular distribution. Due to the good stability of the triangular structure, the stability of the sliding connection between the sewage tank 300 and the mounting frame 100 and the reliability of the mounting frame 100 to hang the sewage tank 300 are further improved.

[0056] Reference Figure 3 , Figure 4 and Figure 8 In some embodiments, the elastic mechanism includes at least one (two are used as an example in the figure) elastic component 510, and the elastic component 510 includes a first elastic member 511, and the two ends of the first elastic member 511 act on the mounting frame 100 and the sewage tank 300 respectively, and the first elastic member 511 applies a force in the direction of the cleaning module 200 (i.e., a force along the first direction F1) to the sewage tank 300. Among them, the first elastic member 511 can be a spring, an elastic rubber block, an elastic rope, etc. For example, the first elastic member 511 is a spring in a compressed state, and the spring is arranged along the first direction F1 (i.e., the length direction is consistent with the first direction F1), and the two ends abut the mounting frame 100 and the sewage tank 300 respectively; for another example, the first elastic member 511 is an elastic rope in a stretched state, and the elastic rope is extended along the first direction F1, and the two ends of the elastic rope are respectively connected to the mounting frame 100 and the sewage tank 300. In this embodiment, the elastic mechanism is composed of only one or more first elastic members 511. The combined force of the first elastic members 511 of each elastic component 510 applied to the sewage tank 300 in the direction of the cleaning module 200 causes the wiper mechanism 400 on one side of the sewage tank 300 to elastically press against the cleaning module 200. The elastic mechanism has a simple structure and is more convenient to assemble.

[0057] Reference Figures 4 to 8In some embodiments, the elastic component 510 also includes a swing arm 512, a supporting portion 513 and a lock 514. The supporting portion 513 is fixed on the sewage tank 300, and the supporting portion 513 is located on the side of the swing arm 512 close to the cleaning module 200. The lock 514 is arranged on the mounting frame 100 or the sewage tank 300. One end of the swing arm 512 (referred to as the first end) is hinged to the mounting frame 100, and the other end of the swing arm 512 (referred to as the second end) is locked by the lock 514. The two ends of the first elastic member 511 elastically abut the swing arm 512 and the supporting portion 513 respectively. In this embodiment, the first end of the swing arm 512 is hinged to the mounting frame 100, and the second end of the swing arm 512 is locked by the lock buckle 514, so that the positions of the swing arm 512 and the mounting frame 100 remain relatively fixed, so that the first elastic member 511 elastically abuts against one end of the swing arm 512, which is equivalent to an indirect elastic action on the mounting frame 100, and because the abutting portion 513 is fixed on the sewage tank 300, the elastic abutment of the first elastic member 511 against one end of the abutting portion 513 is equivalent to an indirect elastic action on the sewage tank 300; and because the abutting portion is located on the side of the swing arm 512 close to the cleaning module 200, the elastic action of the first elastic member 511 on the abutting portion 513 causes the sewage tank 300 to generate an elastic force toward the cleaning module 200, thereby realizing the elastic abutment between the wiper mechanism 400 and the cleaning module 200.

[0058] The abutting portion 513 may be a protruding structure constructed on the sewage tank 300, or may be a separate component fixedly mounted on the sewage tank 300. In the figure of this embodiment, the end of the sliding guide groove 611 on the sewage tank 300 away from the cleaning module 200 is used as the abutting portion, thus eliminating the trouble of additionally providing the abutting portion 513 on the sewage tank 300.

[0059] In some embodiments, the lock buckle 514 has two functions of locking and unlocking the second end of the swing arm 512. When the lock buckle 514 locks the second end of the swing arm 512, the swing arm 512 and the mounting frame 100 remain relatively fixed in position and will not move relative to each other; when the lock buckle 514 unlocks the second end of the swing arm 512, the swing arm 512 can swing freely around its first end. At this time, the swing arm 512 no longer maintains an elastically tight state with the first elastic member 511, and the first elastic member 511 returns to a natural state, and the first elastic member 511 no longer elastically presses against the supporting portion 513. In this way, when it is necessary to disassemble the sewage tank 300, the lock on the second end of the swing arm 512 can be released by the lock buckle 514, so that the first elastic member 511 can return to its natural state, and the first elastic member 511 no longer applies an elastic force to the abutting portion 513, so that the sewage tank 300 can be slid relative to the mounting frame 100 in a direction away from the cleaning module 200 to be removed from the mounting frame 100; when installing the sewage tank 300, the sliding guide groove 611 of the sewage tank 300 is first aligned with the slider 621 on the mounting frame 100, and then the sewage tank 300 is pushed to slide in a direction close to the cleaning module 200 until the wiper mechanism 400 abuts against the cleaning module 200, and finally the second end of the swing arm 512 is locked by the lock buckle 514, so that the first elastic member 511 generates an elastic force toward the cleaning module 200 on the sewage tank 300 through the abutting portion 513, that is, the installation of the sewage tank 300 is completed. The solution of this embodiment makes the disassembly and assembly of the sewage tank 300 more convenient, and it is convenient for the user to disassemble the sewage tank 300 for cleaning.

[0060] Continue to refer to Figures 4 to 8 In this embodiment, the lock 514 includes a pressure rod 5141 and a second elastic member 5142. The pressure rod 5141 is hinged on the mounting frame 100 or the sewage tank 300. The second elastic member 5142 acts on the pressure rod 5141, so that the pressure rod 5141 presses the second end of the swing arm 512 to prevent the swing arm 512 from swinging back to the supporting portion 513; an operating portion 5141a is provided at one end of the pressure rod 5141, so that the user can pry the pressure rod 5141 to release the pressure on the second end of the swing arm 512. In this embodiment, the lock buckle 514 is composed of a pressure rod 5141 and a second elastic member 5142. The second elastic member 5142 exerts an elastic force on the pressure rod 5141, so that the pressure rod 5141 keeps pressing the second end of the swing arm 512, so as to achieve the function of maintaining the locked state, and the lock on the second end of the swing arm 512 is released by prying the operating part 5141a of the pressure rod 5141. The lock buckle 514 has a simple structure, a stable locking state, and a convenient unlocking operation.

[0061] In some embodiments, a first hook portion 512a is provided on the second end of the swing arm 512 facing the pressure rod 5141, and a second hook portion 5141b is provided on the pressure rod 5141, and the second hook portion 5141b buckles the first hook portion 512a. In this embodiment, the pressure rod 5141 buckles the first hook portion 512a by the second hook portion 5141b to achieve compression and locking of the second end of the swing arm 512, and when the operating portion 5141a is bent to disengage the second hook portion 5141b of the pressure rod 5141 from the first hook portion 512a, the second end of the swing arm 512 is unlocked.

[0062] Of course, in some other embodiments, the lock 514 can also adopt an electrically controlled structure. For example, the lock 514 includes an electric telescopic rod. When the electric telescopic rod is in an extended state, it clamps the second end of the swing arm 512 to achieve the function of locking the swing arm 512. When the electric telescopic rod is retracted, the restriction on the second end of the swing arm 512 is released, so that the swing arm 512 can resume free swinging.

[0063] In the figure of this embodiment, the elastic mechanism is set between the hanging plate 110 of the mounting frame 100 (above the sewage tank 300) and the top side of the sewage tank 300 as an example. The top side area of ​​the sewage tank 300 is larger, which is more convenient for setting the elastic mechanism. Of course, in other embodiments, the elastic mechanism can also be set between other positions of the sewage tank 300 (for example, the bottom side or both ends) and the mounting frame 100.

[0064] Reference Figures 2 to 4 In some embodiments, the wiper mechanism 400 is integrated with the sewage tank 300. In this embodiment, the wiper mechanism 400 is integrated on the side of the sewage tank 300 close to the cleaning module 200, so that the wiper mechanism 400 and the sewage tank 300 of the cleaning device can be disassembled and assembled at the same time, which can be done in one step, reducing the assembly steps of the cleaning device and improving the production efficiency of the cleaning equipment; in addition, since the wiper mechanism 400 and the sewage tank 300 are integrated, there is no need to consider the sealing between the wiper mechanism 400 and the sewage tank 300, eliminating the difficulty of sealing design and reducing costs. In addition, the wiper mechanism 400 and the sewage tank 300 are integrated, which will make the wiper mechanism 400 more convenient to form, the structural stability of the wiper mechanism will be better, and the support to the cleaning module 200 will be more stable.

[0065] Reference Figure 3 and Figure 4In some embodiments, the wiping mechanism 400 includes a scraper bar 410 extending obliquely upward from a side of the sewage tank 300 close to the cleaning module 200, and the scraper bar 410 and the outer wall of the sewage tank 300 enclose a water collection tank 302, and the sewage inlet 301 of the sewage tank 300 is set on the groove wall of the water collection tank 302. When the sewage tank 300 is installed on the mounting frame 100, the top side of the scraper bar 410 is pressed against the cleaning module 200. When the cleaning device is working, the dirt on the cleaning module 200 flows along the scraper bar 410 into the water collection tank 302, and the dirt in the water collection tank 302 flows into the sewage tank 300 from the sewage inlet 301 for storage.

[0066] In some embodiments, the walls of the water collection tank 302 located around the sewage inlet 301 are all tilted toward the sewage inlet 301, so that the sewage inlet 301 becomes the lowest position in the water collection tank 302, and the dirt at various positions in the water collection tank 302 will flow toward the sewage inlet 301, and the flow rate will be faster. In this way, the dirt in the water collection tank 302 is accelerated to enter the sewage tank 300, avoiding overflow and residue of dirt in the water collection tank 302.

[0067] Of course, in some other embodiments, the wiper mechanism 400 may also be an independent structure fixedly installed on the sewage tank 300, that is, the wiper mechanism 400 and the sewage tank 300 may be separately arranged.

[0068] Reference Figure 1 and Fig. 9 In this embodiment, the sewage tank 300 includes a box body 310 and a box cover 320. The box cover 320 covers the box body 310. One side of the box cover 320 is hinged to one side of the box body 310, and the other side of the box cover 320 is buckled and fixed to the other side of the box body 310 through a buckle structure 700. By setting the sewage tank 300 as a flip-openable structure, it is convenient for users to clean the inside of the sewage tank 300.
