Description

Technical Field

[0001] The utility model relates to the technical field of cleaning equipment, in particular to a cleaning equipment. Background Art

[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 floor scrubbers and cleaning robots) can scrape off the dirt on the cleaning module (such as a mop or a roller brush) and collect it into a sewage tank through a scraping structure while mopping the floor, so that a relatively clean mop or roller brush can always be used to clean the floor, which has a better cleaning effect and is therefore widely loved by users.

[0003] However, during the cleaning process, the cleaning device continuously scrapes dirt from the mop and stores the dirt into the sewage tank through the sewage inlet, so the sewage inlet of the sewage tank is always kept open. This causes the following defects in the existing cleaning devices: when the cleaning device passes through special areas or special sections (such as cobblestone sections, carpet areas, obstacle sections, etc.), the cleaning device will be bumpy, which may easily cause the sewage in the sewage tank to leak out from the sewage inlet; or, when the cleaning device needs to pass through a section or area that does not need to be cleaned or has been cleaned, the cleaning module will remain off the ground, but because the sewage inlet of the sewage tank is open, sewage may leak from the sewage inlet to the ground, causing secondary pollution. Utility Model Content

[0019] In some embodiments, the sealing member includes a baffle for opening and closing the sewage inlet and a connecting portion provided on the baffle, the connecting portion corresponds one-to-one with the transmission rod, and one end of the transmission rod is connected to the corresponding connecting portion.

[0020] In some embodiments, the baffle is disposed in the sewage tank, the connecting portion is disposed on a side of the baffle facing the sewage inlet, the connecting portion extends out of the sewage inlet, and is hinged to the outer side of the sewage tank.

[0022] In some embodiments, the body is provided with a driving device, and the driving device is connected to the cleaning module and is used to drive the cleaning module to be raised and lowered relative to the body.

[0023] In some embodiments, the driving device includes a hoisting mechanism, and the cleaning module is hoisted by the fuselage through the hoisting mechanism, so that the cleaning module can be installed on the fuselage in a liftable manner.

Moreover, when the cleaning device lifts the cleaning module to pass through a road section or area that does not need to be cleaned or has been cleaned, the lifting of the cleaning module will cause the opening and closing device to close the sewage inlet of the sewage tank, thereby avoiding the sewage leaking to the ground and causing secondary pollution. In addition, since most of the existing cleaning equipment already has the function of lifting the cleaning module, the cleaning equipment of the present invention can choose to reuse the structural design of the existing cleaning equipment with a lifting cleaning module, and only needs to add an additional opening and closing device, which greatly reduces the structural design cost of this embodiment. The opening and closing device can also be designed in the internal space of the cleaning equipment without increasing the external dimensions of the cleaning equipment.

[0037] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0038] It should be noted that all directional indications in the embodiments of the present invention (such as up, down, left, right, front, back...) are only used to explain the relative position relationship, movement status, etc. between the components under a certain specific posture (as shown in the accompanying drawings). If the specific posture changes, the directional indication will also change accordingly.

[0039] It should also be noted that when an element is referred to as being "fixed on" or "disposed on" another element, it may be directly on the other element or there may be an intermediate element at the same time. When an element is referred to as being "connected to" another element, it may be directly connected to the other element or there may be an intermediate element at the same time.

[0040] In addition, the descriptions of "first", "second", etc. in the present utility model are only used for descriptive purposes and cannot be understood as indicating or implying their relative importance or implicitly indicating the number of the indicated technical features. 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.

[0041] The utility model provides a cleaning device, which may be a mopping robot, a sweeping and mopping robot, a handheld floor scrubber, and the like.

[0042] Reference Figure 1 , Figure 2 and Figure 5 In this embodiment, the cleaning device includes a body 100 , a sewage tank 210 , a cleaning module 220 and an opening and closing device 300 .

[0043] Among them, the sewage tank 210 is set on the body 100, and the sewage tank 210 is mainly used to store sewage. For example, it can be used to store sewage generated by the cleaning equipment during the cleaning process, or it can be used to store sewage collected by the cleaning module from the surface of the cleaning object (such as the ground, the table); the sewage tank 210 itself is provided with a sewage inlet 211, and the sewage inlet 211 is used for the sewage collected by the cleaning equipment to flow into the sewage tank 210.

[0044] The cleaning module 220 is an important component of the cleaning device for realizing the cleaning function. The cleaning module 220 is used to clean the surface of an object. When the cleaning device is performing the cleaning task on the surface of an object, the cleaning module 220 will contact the surface of the object to clean the surface of the object. In this embodiment, the cleaning module 220 can be installed on the fuselage 100 in a lifting manner, that is, the cleaning module 220 and the fuselage 100 are not relatively fixed, but can be lifted relative to the fuselage 100; when the cleaning device cleans the surface of an object, if the cleaning device reaches a special area or a special section (such as a carpet area, a cobblestone section, an obstacle section, etc.), the cleaning module 220 will be subjected to an upward force exerted by a protrusion or protrusion on the surface of the object (such as pebbles, thresholds, steps, etc.), and the cleaning module 220 will be relatively lifted relative to the fuselage 100. In addition, the fuselage 100 may also be provided with an electric control mechanism for applying an upward force to the cleaning module 220, so that the cleaning device can actively control the raising or lowering of the cleaning module 220. For example, when the cleaning device crosses an obstacle or a threshold, the cleaning device will actively control the raising of the cleaning module 220, and after crossing the obstacle or the threshold, the cleaning device will actively control the lowering of the cleaning module 220. For another example, when the cleaning device passes through a road section or area that does not need to be cleaned or has been cleaned, in order to avoid the cleaning module from causing stains on the road section or area, the cleaning device can actively control the raising of the cleaning module 220, and after passing through the road section or area, the cleaning device will actively control the lowering of the cleaning module 220. In addition, an operating component for manually lifting the cleaning module 220 can also be provided on the fuselage 100, and the user can manually lift the cleaning module 220 through the operating component, so that the actual application of the cleaning device is more flexible.

[0045] In this embodiment, the opening and closing device 300 is used to control the opening and closing of the sewage inlet 211 of the sewage tank 210, and when the cleaning module 220 is raised relative to the fuselage 100, the opening and closing device 300 closes the sewage inlet 211. The opening and closing device 300 of this embodiment can be electrically controlled, or can be driven by the lifting motion of the cleaning module 220. When the opening and closing device 300 is electrically controlled, the sewage inlet 211 can be directly closed when it is detected that the cleaning module 220 is in a raised state relative to the fuselage 100 (regardless of the raised height), or the sewage inlet 211 can be closed after it is detected that the cleaning module 220 is raised relative to the fuselage 100 to a set height (such as 5mm). When the opening and closing device 300 is driven by the lifting motion, the transmission sensitivity can be designed according to actual needs.

[0046] In some embodiments, when the cleaning module 220 falls back to its original position relative to the fuselage 100, that is, the cleaning device leaves a special area or a special section of road (such as a carpet area, a cobblestone section, an obstacle section, etc.), the cleaning module 220 falls back to a normal cleaning state in contact with the surface of an object relative to the fuselage 100, or the cleaning device has passed a section or area that does not need to be cleaned or has been cleaned, and the cleaning device actively controls the cleaning module 220 to fall back to contact the surface of the object. At this time, the opening and closing device 300 opens the sewage inlet 211, so that the cleaning device can continue to normally send the collected sewage from the sewage inlet 211 into the sewage tank 210. Of course, in some other embodiments, when the opening and closing device 300 is electronically controlled, the opening and closing device 300 may not automatically open the sewage inlet 211 or immediately open the sewage inlet 211 when the cleaning module 220 falls back to its original position relative to the body 100. For example, the cleaning equipment may be designed with a delayed judgment, such as a 2-second delay to determine whether a special area or a special road section has been completely left. If it is determined that the area or road section has been completely left, the opening and closing device 300 may open the sewage inlet 211; otherwise, the opening and closing device 300 may continue to close the sewage inlet 211.

[0047] The cleaning device of this embodiment is provided with a cleaning module 220 mounted on the body 100 in a movable manner that can be lifted and lowered, and an opening and closing device 300 for opening and closing the sewage inlet 211 of the sewage tank 210 is provided. When the cleaning module 220 is lifted upward relative to the body 100 by an external force, the opening and closing device 300 will close the sewage inlet 211 of the sewage tank 210. In this way, when the cleaning device is cleaning special areas or special sections (such as cobblestone sections, carpet areas, obstacle crossing sections, etc.), even if the cleaning module 220 is lifted upward by a protrusion on the ground, that is, the cleaning module 220 is lifted upward relative to the body 100, the opening and closing device 300 will automatically close the sewage inlet 211 of the sewage tank 210 at this time, so as to prevent the sewage in the sewage tank 210 from leaking out of the sewage inlet 211 due to the bumps, thereby avoiding the situation where the leakage of sewage causes secondary pollution to the ground, thereby ensuring the cleaning effect of the cleaning device in special areas or special sections. Furthermore, when the cleaning equipment lifts the cleaning module 220 to pass through a road section or area that does not need to be cleaned or has been cleaned, the lifting of the cleaning module 220 will cause the opening and closing device 300 to close the sewage inlet 211 of the sewage tank 210, and can also prevent the sewage in the sewage tank 210 from leaking to the ground and causing secondary pollution. In addition, since most existing cleaning equipment already has the function of lifting the cleaning module 220, the cleaning equipment of this embodiment can choose to reuse the structural design of the existing cleaning equipment with a lifting cleaning module 220, and only needs to add an additional opening and closing device 300, which greatly reduces the structural design cost of the solution of this embodiment, and the opening and closing device 300 can be designed in the internal space of the cleaning equipment without increasing the external dimensions of the cleaning equipment.

[0048] like Figure 3 As shown, in this embodiment, a scheme of an opening and closing device 300 controlled by electric control is provided. In this embodiment, the opening and closing device 300 includes a detection component 301 and a solenoid valve 302. The solenoid valve 302 is used to control the opening and closing of the sewage inlet 211 of the sewage tank 210. The detection component 301 is used to detect the state of the cleaning module 220 relative to the fuselage 100, and determine whether the cleaning module 220 is in a state of being raised relative to the fuselage 100, or in a state of not being raised relative to the fuselage 100 (i.e., in an initial state relative to the fuselage 100). The detection component 301 is electrically connected to the solenoid valve 302. When the detection component 301 detects that the cleaning module 220 is in a state of being raised relative to the fuselage 100, the solenoid valve 302 is controlled to close the sewage inlet 211. When the detection component 301 detects that the cleaning module 220 is in a non-raised state relative to the fuselage 100, the solenoid valve 302 can be controlled to immediately open the sewage inlet 211, or the state of the cleaning module 220 relative to the fuselage 100 can be continuously detected. When the non-raised state is maintained for a preset period of time (such as 2 seconds), the solenoid valve 302 is controlled to open. This can avoid switching the state of the solenoid valve 302 too frequently.

[0049] The detection component 301 may include a force sensor disposed between the cleaning module 220 and the body 100, and the value of the force sensor will change accordingly when the cleaning module 220 is lifted relative to the body 100; the detection component 301 may also include an optical sensor, and the optical sensor generates a sensing signal when the cleaning module 220 is lifted relative to the body 100. Of course, in other embodiments, the detection component 301 may also be other solutions.

[0050] Reference Figures 4 to 6 In this embodiment, the opening and closing device 300 includes a transmission assembly and a sealing member 310 for opening and closing the sewage inlet 211. The body 100 is connected to the sealing member 310 through the transmission assembly, that is, the opening and closing device 300 of this embodiment is driven and controlled by the lifting and lowering movement of the cleaning module 220. When the cleaning module 220 rises relative to the body 100, the body 100 transmits a force to the sealing member 310 through the transmission assembly to drive the sealing member 310 to close the sewage inlet 211, that is, when the cleaning module 220 rises upward relative to the body 100, the body 100 applies a force to the transmission assembly, and drives the sealing member 310 to move to a position to close the sewage inlet 211 through the transmission assembly. Of course, when the cleaning module 220 is lowered from the raised state relative to the main body 100 to return to the initial position, the main body 100 may transmit a force to the sealing member 310 through the transmission assembly to drive the sealing member 310 to open the sewage inlet 211, or the main body 100 may not apply a force to the transmission assembly, that is, the main body 100 drives the sealing member 310 to open the sewage inlet 211 without the transmission assembly (in this case, other methods may be used to complete the opening of the sealing member 310).

[0051] Here, a solution is introduced in which the sealing member 310 opens the sewage inlet 211 when the cleaning module 220 is lowered from the raised state relative to the fuselage 100 and restored to the initial position. In this solution, the opening and closing device 300 also includes an elastic reset component, which applies a force to the sealing member 310 to move in the direction of opening the sewage inlet 211; when the cleaning module 220 is raised relative to the fuselage 100, the fuselage 100 applies a force to the sealing member 310 through the transmission component, which will keep the sealing member 310 in the position of closing the sewage inlet 211, and when the cleaning module 220 is restored to the initial position relative to the fuselage 100, the fuselage 100 no longer applies a force to the sealing member 310 through the transmission component, and the force applied by the elastic reset component to the sealing member 310 will drive the sealing member 310 to return to the position of opening the sewage inlet 211.

[0052] Reference Figure 4 and Figures 6 to 8In one embodiment, the transmission assembly includes at least one transmission rod 321 (two are used as an example in the figure of this embodiment), and the sewage tank 210 and the cleaning module 220 are relatively fixed (for example, the sewage tank 210 and the cleaning module 220 are fixed on the mounting member (the outer frame 230 shown in the figure), or the sewage tank 210 and the cleaning module 220 are directly fixedly connected) (see Figure 2 ), that is, the sewage tank 210 can follow the cleaning module 220 to rise and fall back relative to the fuselage 100. Among them, the transmission rod 321 is hinged to the sewage tank 210, and the hinge axis of the transmission rod 321 is located between the two ends of the transmission rod 321 (that is, the transmission rod 321 is hinged to the sewage tank 210 at a certain point of this section between its two ends), one end of the transmission rod 321 (referred to as the first end 321a of the transmission rod 321) is connected to the sealing member 310, and the other end of the transmission rod 321 (referred to as the second end 321b of the transmission rod 321) is in contact with the fuselage 100; when the cleaning module 220 is raised relative to the fuselage 100, the fuselage 100 will squeeze the second end 321b of the transmission rod 321, so that the first end 321a of the transmission rod 321 produces a corresponding movement, and then the transmission rod 321 will drive the sealing member 310 to rotate to close the sewage inlet 211.

[0053] In another embodiment, the transmission assembly includes at least one transmission rod 321, which is hinged to the cleaning module 220, and the hinge axis of the transmission rod 321 is located between the two ends of the transmission rod 321, one end of the transmission rod 321 (denoted as the first end 321a of the transmission rod 321) is connected to the sealing member 310, and the other end of the transmission rod 321 (denoted as the second end 321b of the transmission rod 321) is abutted against the fuselage 100; when the cleaning module 220 is raised relative to the fuselage 100, the fuselage 100 squeezes the second end 321b of the transmission rod 321, causing the first end 321a of the transmission rod 321 to produce corresponding movement, and then the transmission rod 321 drives the sealing member 310 to rotate to close the sewage inlet 211. The difference between this embodiment and the previous embodiment is that the transmission rod 321 is directly hinged on the cleaning module 220, and there is no requirement for whether the sewage tank 210 and the cleaning module 220 are relatively fixed, that is, the sewage tank 210 can be relatively fixed with the cleaning module 220, or the sewage tank 210 can be directly fixed on the fuselage 100. In this embodiment. When the sewage tank 210 is not relatively fixed with the cleaning module 220, since the cleaning module 220 does not need to move with the sewage tank 210, the force required to lift the cleaning module 220 relative to the fuselage 100 can be reduced, so that the lifting and lowering movement of the cleaning module 220 is more sensitive during the use of the cleaning device.

[0054] In the above two embodiments, the second end 321b of the transmission rod 321 is in contact with the fuselage 100. This contact makes the fuselage 100 not generate a force to drive the transmission rod 321 to reset on the second end 321b of the transmission rod 321 when the cleaning module 220 is lowered and returned to its original position relative to the fuselage 100. Therefore, the two embodiments can be applied in combination with the elastic reset component, so that when the cleaning module 220 is lowered and returned to its original position relative to the fuselage 100, the sealing member 310 is driven to automatically open the sewage inlet 211 through the action of the elastic reset component. Of course, in some other embodiments, the second end 321b of the transmission rod 321 can also be movably connected with the fuselage 100, so that when the cleaning module 220 is lowered and returned to its original position relative to the fuselage 100, the fuselage 100 also applies a force to reset the transmission rod 321 on the second end 321b of the transmission rod 321, driving the sealing member 310 to automatically open the sewage inlet 211, so that there is no need to combine the elastic reset component.

[0055] It should be noted that in the figures of the present application, the transmission rod 321 and the sealing member 310 are arranged separately. By designing the transmission rod 321 and the sealing member 310 separately, not only can the height required for the transmission assembly as a whole be reduced, so that the overall height of the cleaning module can be smaller, which is conducive to the compact design of the cleaning device, but also the movement stroke of the transmission rod 321 and the sealing member 310 can be smaller, the transmission is more stable, and the sealing member 310 can be prevented from being loosely closed. Of course, in some other embodiments, the transmission rod 321 and the sealing member 310 can also be arranged as one piece (refer to Fig. 9 ), the integrated setting can reduce the number of components and simplify the installation of the transmission components.

[0056] Reference Figure 4 and Figure 6 In some embodiments, the blocking member 310 includes a blocking piece 311 for opening and closing the sewage inlet 211 and a connecting portion 312 provided on the blocking piece 311, the connecting portion 312 corresponds to the transmission rod 321, and the first end 321a of the transmission rod 321 is connected to the corresponding connecting portion 312. When the cleaning module 220 is raised relative to the body 100, the body 100 squeezes the second end 321b of the transmission rod 321, and the first end 321a of the transmission rod 321 drives the blocking piece 311 to move until the blocking piece 311 closes the sewage inlet 211 of the sewage tank 210.

[0057] Reference Figure 4In some embodiments, the baffle 311 is disposed in the sewage tank 210, and the connecting portion 312 is disposed on the side of the baffle 311 facing the sewage inlet 211. The connecting portion 312 extends out of the sewage inlet 211 and is hinged to the outside of the sewage tank 210. By disposing the baffle 311 in the sewage tank 210, when the cleaning module 220 is raised relative to the body 100, the connecting portion 312 is tilted by the first end 321a of the transmission rod 321, so that the connecting portion 312 pulls the baffle 311 outside the sewage inlet 211, so that the baffle 311 covers the sewage inlet 211. This method of covering from the inside is more stable and has a better sealing effect. In addition, a rubber strip can be provided on the periphery of the side of the baffle 311 facing the sewage inlet 211 to better improve the sealing effect of the baffle 311 on the sewage inlet 211.

[0058] Reference Figure 4 In some embodiments, a first torsion spring 41 is provided on the hinge shaft of the transmission rod 321, and the first torsion spring 41 elastically acts on the transmission rod 321, so that the transmission rod 321 remains in contact with the body 100; a second torsion spring 42 is provided on the hinge shaft of the connection part 312, and the second torsion spring 42 applies a force to the connection part 312 to move in the direction of opening the sewage inlet 211. That is, through the action of the first torsion spring 41 and the second torsion spring 42, when the cleaning module 220 is in the initial state (i.e., not raised state) relative to the body 100, the baffle 311 remains in the state of opening the sewage inlet 211, thereby ensuring that the cleaning device can normally collect sewage. Among them, the combination of the first torsion spring 41 and the second torsion spring 42 is essentially a specific implementation scheme of the above-mentioned elastic reset component. Of course, in other embodiments, the elastic reset component can also be composed of other elastic devices, such as an elastic rope or a telescopic spring. The elastic rope or the telescopic spring tightens the connecting portion 312 to keep the baffle 311 in a state of opening the sewage inlet 211. When the cleaning module 220 rises relative to the fuselage 100, the fuselage 100 squeezes the second end 321b of the transmission rod 321, so that the baffle 311 overcomes the elastic tension of the elastic rope or the telescopic spring and closes the sewage inlet 211. When the cleaning module 220 falls back to its original position, the second end 321b of the transmission rod 321 is no longer squeezed by the fuselage 100, and the baffle 311 is reset under the elastic tension of the elastic rope or the telescopic spring to open the sewage inlet 211.

[0059] In some embodiments, the fuselage 100 is provided with a driving device, which is connected to the cleaning module 220 and is used to drive the cleaning module 220 to be raised and lowered relative to the fuselage 100; the driving device may be directly connected to the cleaning module 220, or may be indirectly connected through a middleware. In this embodiment, by providing a driving device for the cleaning device, the cleaning device can actively control the lifting of the cleaning module through the driving device, thereby providing support for the intelligent control design of the cleaning device; for example, the cleaning device can control the cleaning module 220 to adjust to a corresponding state according to the detected area or road section information (for example, when it is detected that an area or road section that does not need to be cleaned or has been cleaned is entered, the cleaning module 220 is controlled to rise relative to the fuselage 100 so that the cleaning module 220 leaves the ground, and when it is detected that an area or road section to be cleaned is entered, the cleaning module 220 is controlled to fall back to contact the ground). Among them, the driving device may be a device with a common motor or cylinder as a power source, or other solutions may be adopted, for example, the driving device includes an electromagnet assembly, and the lifting and lowering adjustment of the cleaning module 220 is achieved by the magnetic attraction control of the electromagnet.

[0060] Reference Figure 1 , Figure 2 and Figure 7 In some embodiments, the driving device includes a hoisting mechanism 110, and the cleaning module 220 is suspended by the hoisting mechanism 110 on the fuselage 100, so that the cleaning module 220 can be installed on the fuselage 100 in a liftable manner, that is, the cleaning module 220 of this embodiment is suspended on the fuselage 100 through the hoisting mechanism 110. Of course, in some other embodiments, the cleaning module 220 and the fuselage 100 can also be connected in other ways, for example, the cleaning module 220 is connected to the fuselage 100 through an elastic connection component, and the elastic connection component applies an upward elastic thrust or pulling force to the cleaning module 220, so that the cleaning module 220 can be installed on the fuselage 100 in a liftable manner; for example, the elastic connection component can include two tension springs, and the two tension springs respectively hang the two ends of the cleaning module 220 on the fuselage 100.

[0061] Reference Figure 2 and Figure 7In some embodiments, the hoisting mechanism 110 includes a motor 111, a winding post 112 and a pull wire 113, the winding post 112 is installed at the driving end of the motor 111, the pull wire 113 is wound on the winding post 112, and the two ends of the pull wire 113 are respectively connected to the cleaning module 220. In this embodiment, the hoisting mechanism 110 adopts a scheme driven by a motor 111, and the cleaning device can actively control the upward rise and downward return of the cleaning module 220 relative to the fuselage 100 by starting the motor 111 to work. In this way, during the cleaning process of the cleaning device, when the cleaning device reaches a special area or a special section (such as a carpet area, a cobblestone section, crossing a threshold, a step, etc.), the cleaning device can control the motor 111 to drive the cleaning module 220 to rise according to the detected area or section information to pass through the special area or special section, so that the cleaning device is more intelligent and can better adapt to the cleaning of complex indoor environments.

[0062] Reference Figure 2 , Figure 7 and Figure 8 In some embodiments, the cleaning device further comprises an outer frame 230, the cleaning module 220 and the sewage tank 210 are fixedly installed in the outer frame 230, and threading parts 231 are respectively provided at both ends of the outer frame 230, and both ends of the pull wire 113 are respectively passed through the threading parts 231 at both ends of the outer frame 230, and the ends of the pull wire 113 are provided with anti-dropping clips 51 to prevent the pull wire 113 from falling off from the threading parts 231. In this embodiment, the cleaning module 220 and the sewage tank 210 are fixedly installed in the outer frame 230 through the two ends of the pull wire 113, and the two ends of the pull wire 113 are respectively connected to the threading parts 231 at both ends of the shell, so that the cleaning module 220 and the sewage tank 210 are relatively fixedly installed. In this way, during the working process of the cleaning device, the sewage tank 210 follows the cleaning module 220 to move up and down relative to the body 100, so that the wiping assembly between the sewage tank 210 and the cleaning module 220 will not move, and a stable wiping effect is ensured.
