[0024] The following clearly and completely describes the technical solutions in the exemplary embodiments of the present disclosure in conjunction with the accompanying drawings of the exemplary embodiments of the present disclosure. The exemplary embodiments described in this specification are only used for illustrative purposes and do not limit the protection scope of the present disclosure, so it should be understood that various modifications and changes can be made to the exemplary embodiments without departing from the protection scope of the present disclosure.

[0025] In describing this disclosure, unless expressly specified and limiting, the terms "first" and "second" are used for descriptive purposes only and are not to be understood as indicating or implying relative importance, the term "plurality" means two or more than two, and the term "and / or" includes any and all combinations of the associated listed items. In particular, reference to "the / said" or "an" object is equally intended to indicate one of a possible plurality of such objects.

[0026] Unless otherwise specified or explained, terms such as "connected," "fixed," etc. should be understood broadly, for example, "connected" may mean fixedly connected, detachably connected, integrally connected, electrically connected, or signal connected, and "connected" may mean directly connected or indirectly connected via an intermediate medium. Those skilled in the art can understand the specific meanings of the above terms in the present disclosure according to specific circumstances.

[0027] Furthermore, in describing the present disclosure, orientation terms such as "above," "below," "inside," and "outside" described in the exemplary embodiments of the present disclosure are merely described based on angles shown in the accompanying drawings and are not to be construed as limitations of the exemplary embodiments of the present disclosure. Also, when a component or feature is connected "above," "below," or "inside," or "outside" of another component(s), depending on the context, it may be directly connected "above," "below," or "inside," or "outside" of the other component(s) or may be indirectly connected "above," "below," or "inside," or "outside" of the other component(s) via an intermediate element.

[0028] As shown in Figure 1, in the related cleaning device, the liquid storage box 2' is detachably connected to the main body 1'. When the cleaning liquid in the liquid storage box 2' is empty, the liquid storage box 2' is removed from the main body 1' and then filled with cleaning liquid. The liquid storage box 2' has an independent structure, which results in relatively high production costs and poor overall consistency, resulting in an unsightly appearance, a relatively high accident rate, and a negative impact on the service life of the cleaning device.

[0029] To solve this problem, this embodiment provides a cleaning device, which may be a sweeping robot, a mop machine, or other types of cleaning devices, such as a floor scrubber. As shown in Figures 2 and 3, the cleaning device includes a main body 1 and a reservoir 2. The reservoir 2 is used to store cleaning liquid, and the reservoir 2 includes a bottom shell 21, which is integrally molded with the main body 1. The cleaning liquid may be water, water with detergent added, or other liquids with cleaning capabilities.

[0030] In the cleaning device provided by this embodiment, the main body 1 supports the reservoir box 2, which is used to store cleaning fluid and supply the necessary cleaning fluid to components such as the wet cleaning structure in the cleaning device. The bottom shell 21 of the reservoir box 2 and the main body 1 are integrally molded, which corresponds to the bottom shell 21 of the reservoir box 2 being integrally molded with the main body 1, i.e., the bottom shell 21 of the reservoir box 2 being an integrated structure, which has good overall neatness, low cost, beautiful appearance, and good reliability. Compared with related art in which the reservoir box 2' has an independent structure, the frequency of repeated disassembly and assembly of the reservoir box 2 is reduced, which reduces the accident rate and maintenance frequency and extends the service life.

[0031] In particular, it should be noted that the bottom shell 21 and the main body 1 are injection molded to achieve the purpose of integrally molding the bottom shell 21 and the main body 1, thereby reducing the number of parts and the steps of part assembly, and thereby reducing production costs.

[0032] In this embodiment, the bottom shell 21 of the reservoir 2 and the main body 1 are integrally molded, and when the reservoir 2 runs low on cleaning fluid, the reservoir 2 can be refilled with cleaning fluid via the cleaning base station. A water bucket is provided within the cleaning base station and is detachably connected to the cleaning base station. A user removes the water bucket from the cleaning base station, fills it with cleaning fluid, and then places the water bucket into the cleaning base station. The water bucket supplies the cleaning fluid needed for wet cleaning to the reservoir 2 of the cleaning device. Alternatively, the cleaning base station can be directly connected to a water pipe, and water can be supplied to the water bucket via the water pipe.

[0033] In one embodiment, as shown in FIGS. 3 and 4, the reservoir 2 further includes a top cover 22, the bottom shell 21 having an open end, and the top cover 22 is disposed over the open end of the bottom shell 21.

[0034] Here, the bottom shell 21 has a housing structure, and the cavity inside the bottom shell 21 provides a storage space for the cleaning liquid. The top cover 22 is provided to cover the open end of the bottom shell 21, and the top cover 22 serves to close the open end of the bottom shell 21, thereby preventing the cleaning liquid from leaking from the bottom shell 21.

[0035] In particular, a sealed space is formed between the top cover 22 and the bottom shell 21, which is used to store the cleaning liquid, and has a good sealing effect.

[0036] In one embodiment, the top cover 22 is made of a transparent material.

[0037] After the assembly of the bottom shell 21 and the top cover 22 of the liquid storage box 2 is completed, the use of a transparent top cover 22 makes it easy to inspect the internal parts of the liquid storage box 2 for missing parts, incorrect assembly, or assembly omissions, thereby providing convenience for subsequent maintenance.

[0038] It should be understood that the bottom shell 21 and the main body 1 are integrally molded, but the bottom shell 21 and the upper cover 22 are not integrally molded for the following reasons: first, the difference in material between the opaque bottom shell 21 and the transparent upper cover 22 makes it difficult to mold them integrally; second, if the bottom shell 21 and the upper cover 22 are integrally molded, after injection is completed, the open end of the bottom shell 21 will be blocked by the upper cover 22, making it impossible to install the internal components of the liquid storage box 2, and it will also be impossible to inspect or repair other structures within the bottom shell 21. After the bottom shell 21 and the main body 1 provided in this embodiment are integrally molded, various components can be installed inside the bottom shell 21 through the open end of the bottom shell 21, and the internal components of the bottom shell 21 can also be inspected. After the initial installation or inspection is completed, the upper cover 22 and the bottom shell 21 are connected.

[0039] Furthermore, the upper cover 22 is made of a plastic material, and the upper cover 22 can be matched in material with the bottom shell 21 and the main body 1, which are integrally molded by injection molding, thereby improving the connection stability between the bottom shell 21 and the upper cover 22.

[0040] 3 and 4, in one embodiment, the cleaning apparatus further includes a wet cleaning structure 4, and the liquid storage box 2 is used to supply cleaning liquid to the wet cleaning structure 4. The liquid storage box 2 supplies cleaning liquid to the wet cleaning structure 4, thereby achieving the function of supplying cleaning liquid to the wet cleaning structure 4 and achieving the purpose of wet mopping the floor.

[0041] In particular, the wet cleaning structure 4 may be a mop cloth structure or a roller brush structure, which has a water-absorbing material such as cotton, and the mop cloth structure can be driven to reciprocate or rotate, or the roller brush structure can be driven to roll, to wet clean the floor surface to be cleaned.

[0042] In one embodiment, as shown in Figures 3 and 4, the cleaning device further comprises a liquid inlet pipe 5, the liquid inlet pipe 5 is disposed in the liquid storage box 2, a water inlet is disposed in the liquid storage box 2, a first end of the liquid inlet pipe 5 communicates with the water inlet, and a second end of the liquid inlet pipe 5 is used to transport cleaning liquid to the internal cavity of the liquid storage box 2.

[0043] The liquid inlet pipe 5 serves to connect the water inlet of the liquid storage box 2 and the internal cavity of the liquid storage box 2, and the liquid inlet pipe 5 is used to transport the cleaning liquid from the water inlet of the liquid storage box 2 to the internal cavity of the liquid storage box 2.

[0044] In one embodiment, as shown in Figures 3 and 4, the cleaning apparatus further includes a liquid outflow pipe assembly 6, which is disposed in the liquid storage box 2, a first end of the liquid outflow pipe assembly 6 communicating with the internal cavity of the liquid storage box 2, and a second end of the liquid outflow pipe assembly 6 communicating with the wet cleaning structure 4, and used to transport the cleaning liquid in the liquid storage box 2 to the wet cleaning structure 4.

[0045] The cleaning liquid in the liquid storage box 2 is transported to the wet cleaning structure 4 through the liquid outlet pipe assembly 6, which serves to connect the liquid storage box 2 and the wet cleaning structure 4 and transport the cleaning liquid to the wet cleaning structure 4, so that the wet cleaning structure 4 realizes the process of wet mopping the floor.

[0046] In particular, a liquid inlet connector is provided on the side of the upper cover 22 of the liquid storage box 2 facing the bottom shell 21, the second end of the liquid inlet pipe 5 is connected to the liquid inlet connector, and a connecting through-hole is provided on the outer wall of the liquid inlet connector, and the connecting through-hole functions as a shower, and the cleaning liquid transported from the liquid inlet pipe 5 passes through the liquid inlet connector and is sprayed into the internal cavity of the liquid storage box 2 through the connecting through-hole.

[0047] It should be understood that it is not necessary to completely seal the space between the liquid inlet pipe 5 and the liquid inlet connector in order to facilitate the flow of the cleaning liquid out of the connecting through-hole.

[0048] 3 and 4, the liquid outflow pipe assembly 6 includes a liquid outflow pipe 61 and a liquid outlet connector 62, where the liquid outflow pipe 61 is disposed in the liquid storage box 2 and communicates with the internal cavity of the liquid storage box 2. A first end of the liquid outlet connector 62 communicates with the liquid outflow pipe 61, and a second end of the liquid outlet connector 62 communicates with the wet cleaning structure 4.

[0049] The liquid outlet pipe 61 is provided in the liquid storage box 2 and communicates with the internal cavity of the liquid storage box 2, and the liquid outlet pipe 61 sucks up the cleaning liquid from the internal cavity of the liquid storage box 2. The first end of the liquid outlet connector 62 communicates with the liquid outlet pipe 61, and the second end of the liquid outlet connector 62 communicates with the wet cleaning structure 4, and the liquid outlet connector 62 plays the role of intermediate communication, so that the cleaning liquid flowing from the liquid outlet pipe 61 is transported to the wet cleaning structure 4 through the liquid outlet connector 62, thereby achieving the purpose of transporting the cleaning liquid to the wet cleaning structure 4.

[0050] In one embodiment, the cleaning device further comprises an overflow structure 7, which is provided on the reservoir box 2 and is used to overflow the cleaning liquid in the reservoir box 2.

[0051] Since the internal space of the liquid storage box 2 is limited, an overflow structure 7 is provided on the upper cover 22 of the liquid storage box 2 to prevent the liquid storage box 2 from being overfilled. If there is too much cleaning liquid in the liquid storage box 2, the cleaning liquid in the liquid storage box 2 can be discharged through the overflow structure 7, preventing the liquid storage box 2 from being overfilled with cleaning liquid and being damaged, and protecting the liquid storage box 2.

[0052] It should be noted that the overflow structure 7 may specifically be an overflow valve, which is generally a one-way valve that restricts the flow direction of the cleaning liquid so that the cleaning liquid can only flow from the inside of the storage box 2 to the outside of the storage box 2.

[0053] It should be noted that the overflow structure 7 may be provided on the upper cover 22 of the liquid storage box 2, and the cleaning liquid can be overflowed and discharged through the overflow structure 7 only when the liquid storage box 2 is filled with cleaning liquid.

[0054] In one embodiment, the bottom shell 21 and top cover 22 are joined by ultrasonication.

[0055] If the bottom shell 21 and the top cover 22 are connected by ultrasonic processing, the following steps are required: First, the clamping step involves first placing the bottom shell 21 and the top cover 22 in the jig, respectively, and then using the welding head to press the top cover 22 into contact with the bottom shell 21. The welding head then applies pressure to press the top cover 22 against the bottom shell 21. Second, in the contact stage, the welding head vibrates vertically at a certain frequency. Because the plastics of the bottom shell 21 and the top cover 22 have poor thermal conductivity and cannot instantly release heat, the mechanical vibration energy is conducted and collected at the contact area between the bottom shell 21 and the top cover 22, also called the welding surface. As the contact area is an interface with a relatively large acoustic resistance, it generates a local high temperature, and the mechanical vibration energy generates heat energy due to the intense friction. Third, the melting stage: when the temperature of the welding surface reaches the melting point of the plastic, the plastic melts and the bottom shell 21 and the top cover 22 are integrated, and then the vibration stops. Fourth, during the pressure holding stage, the welding head continues to apply pressure until the contact area between the bottom shell 21 and the top cover 22 cools and solidifies, and the bottom shell 21 and the top cover 22 solidify and form; Fifth, in the material discharge stage, after the contact area between the bottom shell 21 and the top cover 22 has solidified, the welding head is reset and the welding head no longer applies pressure to the top cover 22, at which time the two plastic products, the bottom shell 21 and the top cover 22, are melted, and the entire ultrasonic welding process is completed.

[0056] Such an ultrasonic welding process can form strong molecular chains for welding purposes, and the welding strength can approach the strength of the raw materials of the bottom shell 21 and the top cover 22 themselves.

[0057] In one embodiment, as shown in Figures 5 to 8, ultrasonic protrusions 221 are provided on one of the top cover 22 and the bottom shell 21, and an ultrasonic surface 211 is provided on the other, and the ultrasonic protrusions 221 are connected to the ultrasonic surface 211, and the connection between the bottom shell 21 and the top cover 22 is achieved by ultrasonic treatment.

[0058] The directly opposite end surfaces of the top cover 22 and the bottom shell 21 are the contact areas between the bottom shell 21 and the top cover 22, and the ultrasonic protrusions 221 are protruding from the bottom shell 21 or the top cover 22. The ultrasonic protrusions 221 can form a molten adhesive under the vibration pressure of ultrasonic waves, providing raw material for the molten fusion of the bottom shell 21 and the top cover 22 and providing reserved locations for the plastic melting. The ultrasonic surface 211 has a planar structure with a relatively high flatness, providing a good attachment location for the molten adhesive, and a strong connection between the ultrasonic protrusions 221 and the ultrasonic surface 211, thereby improving the connection reliability between the bottom shell 21 and the top cover 22.

[0059] In particular, it should be noted that the ultrasonic protrusions 221 may be provided on the side of the top cover 22 facing the bottom shell 21 and the ultrasonic surface 211 may be provided on the side of the bottom shell 21 facing the top cover 22, or the ultrasonic surface 211 may be provided on the side of the top cover 22 facing the bottom shell 21 and the ultrasonic protrusions 221 may be provided on the side of the bottom shell 21 facing the top cover 22.

[0060] It should be understood that in some other embodiments, ultrasonic protrusions 221 are provided on one of the end faces of the top cover 22 and the bottom shell 21 that are close to each other, and ultrasonic grooves are provided on the other, and the ultrasonic protrusions 221 are at least partially disposed within the ultrasonic grooves, and the ultrasonic grooves function as adhesive overflow grooves, which reduce the overflow of adhesive after the ultrasonic protrusions 221 generate molten adhesive.

[0061] Therefore, in this embodiment, the specific form of providing the ultrasonic surface 211 and the ultrasonic protrusions 221 on the bottom shell 21 and the top cover 22 is not limited, and can be adjusted according to the actual production situation.

[0062] In one embodiment, as shown in Figures 5 to 8, the ultrasonic protrusions 221 have a closed ring structure, and the ultrasonic protrusions 221 are arranged along the circumferential direction of the upper cover 22, and the ultrasonic surface 211 has a closed ring structure, and the ultrasonic surface 211 is arranged along the circumferential direction of the bottom shell 21.

[0063] The ultrasonic protrusions 221 are arranged along the circumferential direction of the top cover 22, the ultrasonic protrusions 221 have a closed ring structure, and the ultrasonic protrusions 221 have a continuous full-circle structure. The ultrasonic surface 211 is arranged along the circumferential direction of the bottom shell 21, the ultrasonic surface 211 has a closed ring structure, and the ultrasonic surface 211 has a continuous full-circle structure. With this configuration, the fusion region between the ultrasonic protrusions 221 and the ultrasonic surface 211 is continuous, thereby improving the stability and reliability of the welding between the bottom shell 21 and the top cover 22.

[0064] In one embodiment, the cross section of the ultrasonic protrusion 221 is at least one of a triangle, an arc, and a polygon.

[0065] When the cross section of the ultrasonic protrusion 221 is triangular, it is also called a triangular ultrasonic line, and the volume of the ultrasonic protrusion 221 gradually decreases in the direction in which the upper cover 22 and the bottom shell 21 approach each other, that is, the ultrasonic protrusion 221 has a tapered structure. During the welding process, the molten adhesive formed by the melting of the ultrasonic protrusion 221 covers the ultrasonic surface 211, and the mutual contact area between the bottom shell 21 and the upper cover 22 is continuous, without fusion boundary and boundary stress, the fusion gap is uniform, the welding fastness is improved, and the welding efficiency can be effectively improved.

[0066] Through this ultrasonic welding process, a triangular ultrasonic line is formed on the upper cover 22 of the liquid storage box 2, and when the ultrasonic work is completed, the triangular ultrasonic line on the upper cover 22 is completely fused and bonded with the ultrasonic surface 211 of the main body 1, and the two independent parts of the upper cover 22 and the main body 1 of the liquid storage box 2 are completely connected, thereby achieving the purpose of the integrated liquid storage box 2 and improving the overall integrity while also improving the sealing of the liquid storage box 2.

[0067] It should be understood that this embodiment does not limit the cross-sectional shape of the ultrasonic protrusions 221, and the specific actual cross-sectional shape can be adjusted according to the actual production situation.

[0068] In one embodiment, as shown in FIG. 9, it should be understood that the bottom shell 21 includes a housing and a protective structure 3, and the protective structure 3 is provided within the housing and is used to prevent impact and deformation of the liquid storage box 2.

[0069] Here, the housing has a hollow structure and may have slightly inferior structural strength. For this reason, a protective structure 3 is provided within the housing, which serves to protect the housing, increase the structural strength of the housing, reduce deformation of the entire liquid storage box 2 due to impact, and improve the impact resistance of the integrated structure liquid storage box 2.

[0070] It should be understood that the housing and top cover 22 may be connected by ultrasonic processing, and the protective structure 3 and top cover 22 may be connected by ultrasonic processing.

[0071] In one embodiment, the protective structure 3 comprises a rib plate, the bottom of which is connected to the bottom wall of the housing and the side walls of which are connected to the side walls of the housing.

[0072] Since the bottom wall and the side walls of the housing are connected to each other, a weak situation may occur at the connection position between the bottom wall and the side walls of the housing. Since the bottom of the rib plate and the side walls of the rib plate are respectively connected to the bottom wall and the side walls of the housing, this is equivalent to the rib plate being connected near the connection position between the bottom wall and the side walls of the housing, thereby playing a role in enhancing the structural strength of the connection position.

[0073] In one embodiment, as shown in FIGS. 9 and 10, the rib plate includes a first rib plate 31 and a second rib plate 32, and the first rib plate 31 and the second rib plate 32 are curved on opposite sides.

[0074] The first and second rib plates 31 and 32 are connected to the bottom and side walls of the housing and function as reinforcing ribs, improving the structural strength of the bottom shell 21 as a whole. The first and second rib plates 31 and 32 have a curved structure, which provides greater structural strength and resistance to bending and breaking compared to straight rib plate structures. The first and second rib plates 31 and 32 are curved on opposite sides, i.e., the curved directions of the first and second rib plates 31 and 32 are not the same but are opposite each other. The structural strengths of the first and second rib plates 31 and 32, which are curved in different directions, complement each other. This ensures good structural strength even when both sides of the protective structure 3 are subjected to impacts in opposite directions, further preventing deformation of the liquid storage box 2 upon impact and improving the impact resistance of the integrally structured liquid storage box 2.

[0075] In addition, the number of protective structures 3 may be multiple, and multiple protective structures 3 may be provided within the housing and along the side walls of the housing. The number of protective structures 3 can be appropriately increased for positions where the housing structural strength is relatively weak, and the specific number and installation positions of the protective structures 3 can be adjusted according to actual production conditions.

[0013] One embodiment of the present disclosure provides a cleaning device, which may be a cleaning device such as a sweeping robot or a mop machine, or may be other types of cleaning devices, such as a floor scrubbing machine. The cleaning device may have a mopping function or a sweeping function, or may have both sweeping and mopping functions, so as to automatically complete the sweeping and mopping of a room floor. Referring to FIG. 1, the cleaning device includes a water tank 901 and a wet cleaning structure 904. A water inlet 9016 is provided on the water tank 901, and the water inlet 9016 supplies cleaning liquid to the water tank 901. The water tank 901 is used to store the cleaning liquid, and the water tank 901 is used to supply the cleaning liquid to the wet cleaning structure 904. Here, the cleaning liquid may be water, water with detergent added, or other liquid with cleaning ability.

[0077] In the cleaning device provided by this embodiment, the water tank 901 is used to store cleaning liquid and provides a storage space for the cleaning liquid. The water tank 901 supplies cleaning liquid to the wet cleaning structure 904, thereby realizing the function of supplying cleaning liquid to the wet cleaning structure 904 and achieving the purpose of wet mopping the floor. Here, the wet cleaning structure 904 may be a mop cloth structure or a roller brush structure, which has a water-absorbing material such as cotton, and can be driven to reciprocate or rotate the mop cloth structure or roll the roller brush structure to wet clean the floor surface to be cleaned.

[0078] Here, the cleaning device further includes a water supply pipe 906, which is located between the water storage tank 901 and the wet cleaning structure 904, with a first end of the water supply pipe 906 connected to the water inlet 9016 of the water storage tank 901 and a second end of the water supply pipe 906 connected to the wet cleaning structure 904, so that the cleaning liquid in the water storage tank 901 is transported into the wet cleaning structure 904 through the water supply pipe 906, thereby realizing the cleaning liquid supply and transport process.

[0079] Since the internal space of the water tank 901 is limited, in order to prevent the water tank 901 from being overfilled with cleaning liquid, as shown in Figure 1, the cleaning device further includes an overflow structure 902, which is provided on the water tank 901. When there is too much cleaning liquid in the water tank 901, the cleaning liquid in the water tank 901 can be discharged through the overflow structure 902, thereby preventing the water tank 901 from being overfilled with cleaning liquid and being damaged, and protecting the water tank 901.

[0080] It should be noted that the overflow structure 902 is specifically an overflow valve, and an overflow valve is generally a one-way valve that restricts the flow direction of the cleaning liquid, i.e., the cleaning liquid can only flow in one direction from the inside of the water storage tank 901 to the outside of the water storage tank 901.

[0081] 12 and 13, the water storage tank 901 includes a bottom shell 9011 and an upper cover 9012. The bottom shell 9011 has an open end on one side, and the upper cover 9012 is disposed to cover the open end of the bottom shell 9011, thereby serving to close the open end of the bottom shell 9011. The bottom shell 9011 and the upper cover 9012 may be detachably connected or fixedly connected. An overflow structure 902 is disposed on the upper cover 9012 of the water storage tank 901, and when the water storage tank 901 is filled with cleaning liquid, the overflow structure 902 discharges the overflowing liquid.

[0082] In particular, when the water storage tank 901 is full of cleaning liquid, it means that the capacity of the water storage tank 901 has reached its maximum when the base station supplies cleaning liquid from the water inlet 9016 of the water storage tank 901, and at this time the cleaning liquid overflows from the overflow structure 902, preventing a situation in which the base station continues to supply cleaning liquid to the water storage tank 901 and the cleaning liquid in the water storage tank 901 becomes overfilled. Therefore, when the water storage tank 901 is full of cleaning liquid, the cleaning liquid does not overflow from the overflow structure 902, and only when the liquid pressure ratio in the water storage tank 901 is relatively large, the cleaning liquid overflows from the overflow structure 902.

[0083] When the overflow structure 902 is actually operated, the cleaning liquid overflowing from the overflow structure 902 is likely to flow around the overflow structure 902 in an uncontrolled manner, which may damage other components inside the cleaning apparatus and affect the service life of the cleaning apparatus. Therefore, as shown in Figures 12 and 13, the cleaning apparatus provided by this embodiment further includes an enclosing structure 903, which at least partially surrounds the overflow structure 902 and is used to enclose and guide the cleaning liquid flowing from the overflow structure 902.

[0084] In the cleaning device provided by this embodiment, the enclosing structure 903 at least partially surrounds the overflow structure 902, and the enclosing structure 903 serves to block and enclose the cleaning liquid flowing from the overflow structure 902, preventing the cleaning liquid from overflowing in all directions around the overflow structure 902, thereby reducing the impact on other components of the cleaning device, reducing the frequency and cost of repair and maintenance of the cleaning device, and extending the service life of the cleaning device. At the same time, the cleaning liquid overflowing from the overflow structure 902 is guided out by the enclosing structure 903, which can guide the overflowed cleaning liquid so that it can be discharged in an orderly manner.

[0085] It should be understood that since the overflow structure 902 is provided on the top cover 9012 of the water storage tank 901, the surrounding structure 903 is also provided on the top cover 9012 of the water storage tank 901 to surround any overflowing cleaning liquid.

[0086] In one embodiment, as shown in FIG. 14, the enclosing structure 903 may be a semi-open structure, specifically, the enclosing structure 903 has an open end so that the cleaning liquid flowing from the overflow structure 902 flows out through the open end of the enclosing structure 903.

[0087] When a relatively large amount of cleaning liquid overflows from the overflow structure 902, it may be difficult for the surrounding structure 903 to completely contain the overflowed cleaning liquid, and the overflowed cleaning liquid may still overflow from the surrounding structure 903, resulting in a situation where the cleaning liquid overflows disorderly. Therefore, the surrounding structure 903 is provided with an open end, and the surrounding structure 903 is not a completely sealed structure, so that the overflowed cleaning liquid can flow out from the open end of the surrounding structure 903 and serve to discharge the overflowed cleaning liquid, and in this case, the open end of the surrounding structure 903 functions as a drain to guide the cleaning liquid.

[0088] In particular, the outer shape of the overflow structure 902 may be selected as a cylindrical structure, and the surrounding structure 903 may be selected as a U-shaped structure, which includes a circular arc portion 9031 and two straight portions 9032, the circular arc portion 9031 being wrapped around the outside of the overflow structure 902 and serving to surround the cleaning liquid, and both ends of the circular arc portion 9031 being connected to two straight portions 9032 correspondingly, which serve to surround the cleaning liquid while guiding and directing the overflowed cleaning liquid under the stretching action of the straight portions 9032 themselves. It should be understood that the U-shaped surrounding structure 903 corresponds to surrounding three sides of the overflow structure 902, with the remaining side being open for discharging the overflowed cleaning liquid.

[0089] In one embodiment, a guide inclined surface 9013 is provided in a portion of the water storage tank 901 that is inside the surrounding structure 903, and the guide inclined surface 9013 is inclined in a direction away from the overflow structure 902 and is used to guide the cleaning liquid flowing from the overflow structure 902.

[0090] The top surface of the water storage tank 901 and the two straight portions 9032 of the surrounding structure 903 essentially surround one groove structure, and the groove structure serves to guide any overflowing cleaning liquid; that is, the portion of the top surface of the upper cover 9012 inside the surrounding structure 903 corresponds to the groove bottom of the groove structure, and the opposing side surfaces of the two straight portions 9032 in the surrounding structure 903 correspond to the side walls of the groove structure. It should be understood that a guide inclined surface 9013 is provided in a portion of the water storage tank 901 located inside the surrounding structure 903, i.e., the groove bottom of the groove structure is substantially inclined, and at the same time, the guide inclined surface 9013 is inclined toward a direction away from the overflow structure 902, so that the cleaning liquid overflowing from the overflow structure 902 flows to the open end of the surrounding structure 903 through the guide inclined surface 9013 under the guiding action of the guide inclined surface 9013, thereby increasing the speed at which the cleaning liquid is discharged from the open end of the surrounding structure 903 and improving the timeliness and effectiveness of the liquid discharge.

[0091] In one embodiment, as shown in FIG. 14, the water tank 901 is provided with a restricting structure 9014, which is used to restrict the enclosing structure 903.

[0092] The water tank 901 is provided with a limiting structure 9014, which limits the position of the surrounding structure 903, prevents the surrounding structure 903 from being displaced too much, and ensures the positional stability of the surrounding structure 903.

[0093] Specifically, the upper cover 9012 of the water storage tank 901 is provided with a reinforcing rib, which includes a plurality of horizontal and vertical ribs arranged crosswise, and serves to reinforce the upper cover 9012. Here, the reinforcing rib around the overflow structure 902 resembles a U-shaped structure, which can effectively prevent the overflow structure 902 from overflowing. At this time, the U-shaped reinforcing rib is adapted to the outer shape of the U-shaped surrounding structure 903, and the U-shaped reinforcing rib not only reinforces the structure of the upper cover 9012 but also restricts the surrounding structure 903.

[0094] In one embodiment, the side of the enclosing structure 903 closest to the overflow structure 902 is at least partially affixed to the overflow structure 902 and the side of the enclosing structure 903 away from the overflow structure 902 is at least partially affixed to the restricting structure 9014 .

[0095] In other words, both sides of the arc portion 9031 of the enclosing structure 903 are respectively attached to the overflow structure 902 and the restricting structure 9014, whereby the arc portion 9031 blocks the overflowing cleaning liquid, and at the same time, under the cooperative action of the overflow structure 902 and the restricting structure 9014, the arc portion 9031 is equivalent to being sandwiched between the overflow structure 902 and the restricting structure 9014, thereby improving the positional stability of the arc portion 9031. The outer surface of the straight portion 9032 of the enclosing structure 903 is attached to the restricting structure 9014, and the inner surface of the straight portion 9032 of the enclosing structure 903 can guide the overflowing cleaning liquid.

[0096] In particular, it should be noted that the enclosing structure 903 is higher than the restricting structure 9014 to improve the enclosing effect of the enclosing structure 903 on the cleaning liquid.

[0097] In one embodiment, the surrounding structure 903 is made of sealed foam cotton, and while the surrounding structure 903 plays an enclosing role, it also has sealing and waterproofing effects, preventing overflowing water from leaking through the gap between the surrounding structure 903 and the water storage tank 901, and providing good sealing.

[0098] In one embodiment, the cleaning device further comprises a protective cover, the protective cover being placed on top of the water reservoir 901 and the enclosing structure 903 being sandwiched between the protective cover and the water reservoir 901 .

[0099] Specifically, the protective cover is disposed above the upper cover 9012 in the water tank 901, and serves to isolate and protect the upper cover 9012. The surrounding structure 903 is sandwiched between the protective cover and the upper cover 9012 of the water tank 901, and the two sides of the surrounding structure 903 abut against the inner wall of the protective cover and the outer wall of the upper cover 9012, respectively, and the elasticity of the surrounding structure 903 is utilized to clamp and fix the surrounding structure 903.

[0100] In one embodiment, the containment structure 903 can direct cleaning fluid that overflows from the overflow structure 902 to the wet cleaning structure 904 .

[0101] Because the wet cleaning structure 904 requires a large amount of cleaning liquid, the surrounding structure 903 can guide the cleaning liquid that overflows from the overflow structure 902 to the wet cleaning structure 904, not only preventing the overflowing cleaning liquid from becoming a harmful liquid, but also supplying the wet cleaning structure 904 with the cleaning liquid it needs, realizing the reuse of waste, reducing the waste of cleaning liquid, and at the same time reducing damage to other parts caused by the overflowing cleaning liquid, and extending the service life of the cleaning device.

[0102] In one embodiment, as shown in Figures 14 and 15, the water storage tank 901 is provided with a flowing water trough 9015, a first end of the flowing water trough 9015 is used to receive the cleaning liquid flowing from the open end of the enclosing structure 903, and a second end of the flowing water trough 9015 is used to discharge the cleaning liquid, for example, the second end of the flowing water trough 9015 may be connected to the wet cleaning structure 904.

[0103] Specifically, a flowing water trough 9015 is provided on the bottom shell 9011 of the water storage tank 901, and the flowing water trough 9015 is essentially a through-slot structure, and the first end of the flowing water trough 9015 is used to receive water flowing from the open end of the surrounding structure 903, and the second end of the flowing water trough 9015 is connected to the wet cleaning structure 904, that is, the water inlet of the flowing water trough 9015 is docked with the opening of the surrounding structure 903, and the cleaning liquid flowing from the open end of the surrounding structure 903 flows into the flowing water trough 9015 through the water inlet of the flowing water trough 9015, and then the cleaning liquid is discharged into the wet cleaning structure 904 from the water outlet of the flowing water trough 9015, thereby fulfilling the function of assisting in supplying water to the wet cleaning structure 904.

[0104] 15 and 16, the running water trough 9015 is provided at a portion of the bottom shell 9011 where no open end is provided. In other words, the running water trough 9015 is provided at the edge position of the bottom shell 9011 and corresponds to a notch in the bottom shell 9011, so that the installation positions of the running water trough 9015 on the bottom shell 9011 and the top cover 9012 do not affect each other.

[0105] In one embodiment, a sloped surface 151 is provided at the bottom of the flow trough 9015, and the sloped surface 151 is sloped away from the opening direction of the surrounding structure 903 so that the cleaning liquid flowing from the open end of the surrounding structure 903 is guided to the wet cleaning structure 904 via the sloped surface 151.

[0106] An inclined surface 151 is provided at the bottom of the groove of the flow trough 9015, and the inclined surface 151 is inclined in a direction away from the opening direction of the surrounding structure 903. Under the guiding action of the inclined surface 151, the cleaning liquid in the flow trough 9015 flows through the inclined surface 151 to the wet cleaning structure 904, increasing the speed at which the overflowing cleaning liquid is discharged from the flow trough 9015 and improving the timeliness and effectiveness of drainage.

[0107] In one embodiment, a reinforcing rib 152 is provided at the groove bottom of the flow trough 9015. The reinforcing rib 152 is provided at the groove bottom of the flow trough 9015, and the reinforcing rib 152 serves to reinforce the structure of the groove bottom of the flow trough 9015, thereby increasing the structural strength of the flow trough 9015 and extending its service life.

[0108] If the inclined surface 151 were directly machined on the end surface of the bottom shell 9011 of the water storage tank 901, it would be equivalent to cutting the end surface of the bottom shell 9011, which would result in a reduction in the structural strength of the bottom shell 9011 and could affect the realization of other functions of the water storage tank 901. Therefore, the reinforcing rib 152 provided in this embodiment is protruded from the groove bottom of the water trough 9015, so that it not only does not affect the structural strength of the water storage tank 901, but also does not affect the realization of other functions of the water storage tank 901.

[0109] In one embodiment, the number of reinforcing ribs 152 is plural, and the reinforcing ribs 152 are arranged parallel to each other at intervals to further reinforce the structure of the water tank 901 .

[0110] It should be understood that a transport channel may be formed between two adjacent reinforcing ribs 152, which is used to guide the cleaning liquid and can divert any overflowing cleaning liquid.

[0111] In one embodiment, the cleaning device further comprises a main body 905, and the water tank 901 is disposed within the main body 905. Here, the main body 905 is provided with a communication hole 9051, and the running water trough 9015 communicates with the wet cleaning structure 904 through the communication hole 9051.

[0112] A water storage tank 901 is provided in the main body 905, and the main body 905 serves to support and house the water storage tank 901. The running water trough 9015 communicates with the wet cleaning structure 904 through a communication hole 9051 in the main body 905, and the communication hole 9051 serves as an intermediate communication, so that the cleaning liquid flowing from the water outlet of the running water trough 9015 is discharged to the wet cleaning structure 904 through the communication hole 9051.

[0113] In particular, the communication hole 9051 is arranged along the vertical direction, and the communication hole 9051 falls directly into the wet cleaning structure 904 under the action of its own gravity.

[0114] In particular, it should be noted that the communication holes 9051 have a hole structure as straight as possible in order to avoid the communication holes 9051 having a curved structure from affecting the discharge speed of the cleaning liquid.

[0115] The working process of the cleaning device provided in this embodiment is as follows: If there is too much cleaning liquid in the water storage tank 901 and the liquid pressure in the water storage tank 901 is too high, the cleaning liquid in the water storage tank 901 can be discharged through the overflow structure 902, and the surrounding structure 903 blocks and surrounds the cleaning liquid that has overflowed from the overflow structure 902. Under the guidance of the guiding inclined surface 9013, the cleaning liquid that has overflowed from the overflow structure 902 flows through the guiding inclined surface 9013 to the opening end of the surrounding structure 903. The cleaning liquid flowing from the opening end of the surrounding structure 903 flows from the water inlet of the flowing water trough 9015 into the flowing water trough 9015. Under the guidance of the inclined surface 151, the cleaning liquid in the flowing water trough 9015 flows through the inclined surface 151 and the connecting hole 9051 to the wet cleaning structure 904, thereby realizing the auxiliary function of supplying water to the wet cleaning structure 904.

[0116] The cleaning device provided in this embodiment adopts a sealed waterproofing measure to prevent the situation where water overflows from the overflow structure 902 of the water storage tank 901 and flows uncontrollably, and the surrounding structure 903 is enclosed on three sides with an open side, so that the excess cleaning liquid inevitably generated during the normal operation of the cleaning device is converted into water that does not cause any adverse effects, thereby ensuring the normal service life of the cleaning device, reducing the number of maintenance times of the cleaning device to a certain extent, and improving the user experience.

[0117] This embodiment is similar to the above embodiment, but the communication path between the surrounding structure 903 and the wet cleaning structure 904 and the specific structure of the surrounding structure 903 are different.

[0118] As shown in Figures 17 to 20, the cleaning device provided by this embodiment further includes a guide tube 907, and the surrounding structure 903 is a closed-ring structure. The surrounding structure 903 is attached around the overflow structure 902 and the guide tube 907, and the cleaning liquid flowing from the overflow structure 902 flows out through the guide tube 907.

[0119] Here, the overflow structure 902, the surrounding structure 903 and the guide pipe 907 are provided on the upper cover 9012 of the water storage tank 901, and the surrounding structure 903 is attached around the overflow structure 902 and the guide pipe 907. By surrounding the overflow structure 902 and the guide pipe 907, the surrounding structure 903 can avoid disorderly flow of the cleaning liquid flowing from the overflow structure 902 while also guiding the cleaning liquid directly into the guide pipe 907.

[0120] It should be understood that if the flow rate of cleaning liquid flowing from the overflow structure 902 is relatively large, the height of the surrounding structure 903 of the sealed structure may need to be higher than the height of the overflow structure 902, or the gap between the surrounding structure 903 of the sealed structure and the overflow structure 902 may need to be relatively large in order to ensure that a certain amount of cleaning liquid is stored.

[0121] In one embodiment, the guide tube 907 may be connected to the wet cleaning structure 904, and the cleaning liquid flowing from the overflow structure 902 flows to the wet cleaning structure 904 through the guide tube 907, and the guide tube 907 acts as an intermediate connection to transport the cleaning liquid to the wet cleaning structure 904 in a specific direction.

[0122] The guide tube 907 may be of a substantially vertical structure, so that the cleaning liquid falls directly into the wet cleaning structure 904 through the guide tube 907 under the action of its own gravity, avoiding the curved guide tube 907 from affecting the discharge speed of the cleaning liquid.

[0123] In one embodiment, the cleaning device further comprises a cover plate 8, which has an opening on the side of the enclosing structure 903 away from the water tank 901, and the cover plate 8 is disposed to cover the enclosing structure 903 and close the opening.

[0124] The enclosing structure 903 has an opening on the side away from the upper cover 9012, and if the flow rate of the cleaning liquid flowing from the overflow structure 902 is relatively large, it may overflow from the opening before being discharged from the guide pipe 907. For this reason, the cover plate 8 is provided to cover the enclosing structure 903 and close the opening, so that the cover plate 8 plays a sealing and blocking role, and the cleaning liquid flowing from the overflow structure 902 flows in a specific direction into the guide pipe 907 and is discharged to the wet cleaning structure 904.

[0125] When the surrounding structure 903 is attached around the overflow structure 902 and the guide tube 907, the end of the surrounding structure 903 facing the overflow structure 902 is the large end, and the end of the surrounding structure 903 away from the overflow structure 902 is the small end, and the shape of the cover plate 8 is adapted to the shape of the surrounding structure 903, and the cover plate 8 also has both a large end and a small end. Of course, in other embodiments, the shapes of the surrounding structure 903 and the cover plate 8 may be adjusted appropriately.

[0126] In one embodiment, a storage space is formed between the cover plate 8, the water storage tank 901 and the surrounding structure 903, and the storage space is used to store the cleaning liquid flowing from the overflow structure 902 and prevent overflow.

[0127] Specifically, the top wall of the storage space is the cover plate 8, the bottom wall of the storage space is the upper cover 9012, and the side wall of the storage space is the surrounding structure 903; that is, under the cooperative action of the cover plate 8, the upper cover 9012, and the surrounding structure 903, a relatively sealed space is formed, and the storage space functions to temporarily store the cleaning liquid flowing from the overflow structure 902 and prevent the cleaning liquid from overflowing.

[0128] In one embodiment, the enclosure structure 903 and the top cover 9012 of the water tank 901 are one-piece molded structures, which reduces the number of parts to be assembled and reduces production costs.

[0129] In one embodiment, the cover plate 8 is adhered to the enclosing structure 903 by an adhesive material.

[0130] Here, the adhesive member may be a double-sided tape or adhesive liquid, etc., so that the cover plate 8 is fixed to the surrounding structure 903 by adhesion, which makes the process simple and reduces the production cost.

[0131] In one embodiment, one of the surrounding structure 903 and the cover plate 8 is provided with a mounting post, and the other is provided with a mounting hole 81 , through which the mounting post is provided.

[0132] Here, the mounting posts may be positioning pins or fixing pins or bolts, and the mounting posts are provided through the mounting holes 81 to realize the fixing between the surrounding structure 903 and the cover plate 8 .

[0133] After the cover plate 8 is attached to the surrounding structure 903 with double-sided tape, the mounting posts are installed through the mounting holes 81, thereby achieving double fixing function and further improving the fixing effect.

[0134] In one embodiment, the cover plate 8 is provided with fixing holes 82, and fixing members are provided through the fixing holes 82 and the upper cover 9012, and are used for fixing between the cover plate 8 and the water storage tank 901.

[0135] Here, the fixing member may be a positioning pin, a fixing pin, or a bolt, and when the cover plate 8 is attached to the water tank 901, the fixing member is installed through the fixing hole 82 and the upper cover 9012. At this time, a first end of the cover plate 8 is fixed to the surrounding structure 903 via the mounting post, and a second end of the cover plate 8 is fixed to the upper cover 9012 via the fixing member, thereby improving the connection stability and fixing effect of the cover plate 8.

[0136] In one embodiment, the cover plate 8 may be made of a hard material, such as a PET material, and has good structural strength.

[0137] The working process of the cleaning device provided in this embodiment is as follows: When there is too much cleaning liquid in the water storage tank 901 and the liquid pressure in the water storage tank 901 is too high, the cleaning liquid in the water storage tank 901 is discharged through the overflow structure 902, and the cleaning liquid overflowing from the overflow structure 902 flows through the guide slope 9013 and along the inner wall of the enclosing structure 903 into the guide pipe 907 under the guidance of the guide slope 9013, and the enclosing structure 903 and the cover plate 8 function to block and enclose the cleaning liquid, and then the cleaning liquid flows through the guide pipe 907 to the wet cleaning structure 904, thereby realizing the function of auxiliary water supply to the wet cleaning structure 904.

[0138] An embodiment of the present disclosure provides a liquid storage box for a cleaning machine, which may be a cleaning machine such as a sweeping cleaning robot or a mop machine, or may be another type of cleaning machine such as a floor scrubber. As shown in Figure 21 , the liquid storage box for the cleaning machine includes a tank body 911 and a liquid discharge structure 912. The tank body 911 is used to store cleaning liquid, and the liquid discharge structure 912 is disposed within the tank body 911. The liquid discharge structure 912 includes a liquid discharge inclined surface structure 9121 and a liquid discharge pipe 9122. A first end of the liquid discharge pipe 9122 is connected to a bottom end of the liquid discharge inclined surface structure 9121, and a second end of the liquid discharge pipe 9122 is provided with a liquid discharge port. Here, the cleaning liquid in the tank body 911 is guided via the liquid discharge inclined surface structure 9121 to the first end of the liquid discharge pipe 9122 and is discharged to the outside of the tank body 911 through the liquid discharge port of the liquid discharge pipe 9122. Here, the cleaning liquid may be water, or water with added detergent, or any other liquid with cleaning ability.

[0139] The liquid discharge inclined surface structure 9121 includes an inclined surface and a bottom end connected to each other, the inclined surface being inclined relative to a horizontal plane, the first end of the inclined surface away from the liquid discharge pipe 9122 being the top end, and the second end of the inclined surface close to the liquid discharge pipe 9122 being the bottom end, which can be arranged parallel to the horizontal plane, and in this case the inclined surface is inclined downward in a direction closer to the liquid discharge pipe 9122.

[0140] It should be understood that the cleaning device storage box provided in this embodiment has a tank body 911 used to store cleaning liquid, a liquid discharge structure 912 provided in the tank body 911, and a liquid discharge slope structure 9121 of the liquid discharge structure 912 to maximize the discharge of cleaning liquid from the tank body 911. During actual use, the liquid discharge slope structure 9121 is at least partially inclined relative to the horizontal plane, and the cleaning liquid in the tank body 911 flows from the liquid discharge slope structure 9121 to the bottom end of the liquid discharge slope structure 9121 under the effect of gravity. A first end of a liquid discharge pipe 9122 is connected to the bottom end of the liquid discharge slope structure 9121, and the first end directly receives the cleaning liquid at the bottom end of the liquid discharge slope structure 9121 to facilitate the cleaning liquid being discharged into the liquid discharge pipe 9122. A liquid discharge port is provided at a second end of the liquid discharge pipe 9122, and the liquid discharge port is used to discharge the cleaning liquid in the liquid discharge pipe 9122 to the outside of the tank body 911. In this way, the liquid discharge inclined surface structure 9121 and the liquid discharge pipe 9122 work together to discharge the cleaning liquid at a high speed and with high efficiency, which is advantageous for thoroughly discharging the cleaning liquid from the tank body 911.

[0141] In some embodiments, a water pump is connected to the second end of the liquid discharge pipe 9122, and under the pumping action of the water pump, the cleaning liquid is sucked into the liquid discharge pipe 9122 and discharged outside the tank body 911 through the liquid discharge port.

[0142] In one embodiment, as shown in Figure 21, if the height of a first end of the liquid discharge inclined surface structure 9121 away from the liquid discharge pipe 9122 is h1 and the height of a second end of the liquid discharge inclined surface structure 9121 closer to the liquid discharge pipe 9122 is h2, then h1 > h2.

[0143] It should be understood that if the heights of both ends of the liquid discharge inclined surface structure 9121 are approximately the same and the liquid discharge inclined surface structure 9121 is approximately horizontal, the cleaning liquid in the tank body 911 will disperse and flow through the liquid discharge inclined surface structure 9121, making it difficult to cleanly discharge the cleaning liquid in the tank body 911.

[0144] Therefore, the height h1 of the first end of the liquid discharge slope structure 9121 provided in this embodiment, which is remote from the liquid discharge pipe 9122, is higher than the height h2 of the second end of the liquid discharge slope structure 9121, which is close to the liquid discharge pipe 9122.

[0145] The inclined surface of the liquid discharge inclined surface structure 9121 functions as a slide, and under the guiding action of the inclined surface, the cleaning liquid in the tank body 911 can flow from the top end, which is at a relatively high position, to the bottom end, which is at a relatively low position, so that the cleaning liquid in the tank body 911 can finally accumulate at the bottom end of the liquid discharge inclined surface structure 9121, thereby realizing the function of the cleaning liquid in the tank body 911 gathering in a direction closer to the liquid discharge pipe 9122, and allowing the cleaning liquid in the tank body 911 to be discharged smoothly and completely.

[0146] In one embodiment, h1-h2>1 mm.

[0147] If h1-h2>1 mm, this means that the height difference between the first end of the liquid discharge slope structure 9121, which is far from the liquid discharge pipe 9122, and the second end of the liquid discharge slope structure 9121, which is close to the liquid discharge pipe 9122, is relatively small. In this case, the heights of both ends of the liquid discharge slope structure 9121 are considered to be approximately the same, making it difficult for the liquid discharge slope structure 9121 to fulfill its role of guiding the cleaning liquid in the tank body 911. At the same time, the cleaning liquid in the tank body 911 will be evenly distributed on the liquid discharge slope structure 9121, making it difficult to cleanly discharge the cleaning liquid in the tank body 911. Therefore, the height difference between the first end of the liquid discharge inclined surface structure 9121 provided in this embodiment, which is far from the liquid discharge pipe 9122, and the second end of the liquid discharge inclined surface structure 9121, which is close to the liquid discharge pipe 9122, is greater than 1 mm, so that there is a significant difference in height between the two ends of the liquid discharge inclined surface structure 9121, which can guide the cleaning liquid in the tank body 911. At the same time, the cleaning liquid in the tank body 911 accumulates at the second end of the liquid discharge inclined surface structure 9121, which is close to the liquid discharge pipe 9122, so that the cleaning liquid in the tank body 911 can be discharged as cleanly as possible.

[0148] In one embodiment, as shown in FIG. 21, the liquid discharge slope structure 9121 is provided on the inner wall of the tank body 911 .

[0149] Here, the liquid discharge inclined surface structure 9121 and the tank body 911 may be separate structures, or the inner wall of the top or bottom wall of the tank body 911 itself may be inclined, and the inclined inner wall further forms the liquid discharge inclined surface structure 9121, which can guide the cleaning liquid inside the tank body 911 without adding an inclined guide plate inside the tank body 911, reduce the number of parts, and cut production and processing costs.

[0150] In one embodiment, a liquid discharge groove 91211 is further provided at the bottom end of the liquid discharge inclined surface structure 9121, and a first end of the liquid discharge pipe 9122 is connected to the bottom end of the liquid discharge inclined surface structure 9121 via the liquid discharge groove 91211, and the liquid discharge pipe 9122 has a liquid discharge hole communicating with the liquid discharge groove 91211, so that the cleaning liquid in the liquid discharge groove 91211 is discharged into the liquid discharge pipe 9122 through the liquid discharge hole and further discharged to the outside of the tank body 911.

[0151] Specifically, a liquid discharge groove 91211 is provided at approximately the middle of the bottom end of the liquid discharge slope structure 9121, and a first end of the liquid discharge pipe 9122 is connected to the bottom end of the liquid discharge slope structure 9121 via the liquid discharge groove 91211, which serves as an intermediate connection to improve the connection reliability between the liquid discharge pipe 9122 and the bottom end of the liquid discharge slope structure 9121. The liquid discharge pipe 9122 communicates with the liquid discharge groove 91211, which corresponds to setting the cleaning liquid suction position of the liquid discharge pipe 9122 within the liquid discharge groove 91211 of the groove structure, and after the cleaning liquid in the tank body 911 is guided to the liquid discharge groove 91211 by the inclined surface of the liquid discharge slope structure 9121, the liquid discharge groove 91211 provides a certain amount of storage space for the cleaning liquid, making it convenient for the liquid discharge pipe 9122 to suction and discharge the cleaning liquid.

[0152] In one embodiment, the height of the groove bottom of the liquid discharge groove 91211 is lower than the height of the bottom end of the liquid discharge inclined surface structure 9121, and the cleaning liquid in the tank body 911 is configured to be guided into the liquid discharge groove 91211 through the liquid discharge inclined surface structure 9121.

[0153] Since the height of the groove bottom of the liquid discharge groove 91211 is lower than the height of the bottom end of the liquid discharge inclined surface structure 9121, the groove bottom of the liquid discharge groove 91211 is actually at the lowest position, and the liquid discharge groove 91211 further plays a guiding and collecting role, so that even if the total amount of cleaning liquid in the tank body 911 is relatively small, the cleaning liquid in the tank body 911 can flow to the groove bottom of the liquid discharge groove 91211 to the maximum extent, and the liquid discharge pipe 9122 can suck up and discharge the cleaning liquid.

[0154] In some embodiments, the side walls of the liquid discharge groove 91211 are inclined relative to the bottom wall of the liquid discharge groove 91211, so that the side walls of the liquid discharge groove 91211 also serve as a guide.

[0155] In some embodiments, the bottom end of the liquid discharge inclined surface structure 9121 and the liquid discharge groove 91211 are formed as a single unit, and there is no gap between the bottom end of the liquid discharge inclined surface structure 9121 and the liquid discharge groove 91211, thereby reducing the risk of liquid leakage. Specifically, in actual processing and production, the inner wall of the tank body 911 may be processed into the liquid discharge inclined surface structure 9121 that is at least partially inclined with respect to the horizontal plane, and a groove may be processed into the inner wall of the tank body 911 at a position corresponding to the liquid discharge pipe 9122 to form the liquid discharge groove 91211.

[0156] In one embodiment, as shown in Figure 21, a liquid discharge connector 11 is provided at the bottom of the liquid discharge groove 91211, the liquid discharge connector 11 is connected to the first end of the liquid discharge pipe 9122, and a communicating hole is provided on the outer wall of the liquid discharge connector 11.

[0157] A liquid discharge connector 11 is provided at the bottom of the groove for discharging the cleaning liquid, and is connected to a first end of a liquid discharge pipe 9122. The liquid discharge connector 11 serves to fix the liquid discharge pipe 9122 to the liquid discharge groove 91211, preventing the liquid discharge pipe 9122 from shifting position due to violent shaking and improving the positional stability of the liquid discharge pipe 9122. A communication hole is provided on the outer wall of the liquid discharge connector 11, and the communication hole serves as an intermediate communication hole so that the cleaning liquid in the liquid discharge groove 91211 flows into the liquid discharge pipe 9122 through the communication hole, thereby realizing the cleaning liquid transport and liquid discharge process.

[0158] In this way, the connection reliability between the liquid discharge pipe 9122 and the liquid discharge connector 11 is improved, and at the same time, a communication effect between the liquid discharge groove 91211 and the liquid discharge pipe 9122 is achieved, thereby improving the connection stability of the liquid discharge pipe 9122 and achieving the purpose of discharging the cleaning liquid.

[0159] In some embodiments, the liquid discharge connector 11 is provided substantially at the center position of the liquid discharge groove 91211, i.e., the liquid discharge groove 91211 is provided surrounding the periphery of the liquid discharge connector 11. In this case, the side wall of the liquid discharge groove 91211 closer to the liquid discharge slope structure 9121 guides the cleaning liquid on the liquid discharge slope structure 9121 to the liquid discharge groove 91211, and the side wall of the liquid discharge groove 91211 away from the liquid discharge slope structure 9121 functions as a baffle to prevent the cleaning liquid from overflowing from the liquid discharge groove 91211.

[0160] In some other embodiments, when the liquid discharge groove 91211 is not provided at the bottom end of the liquid discharge inclined surface structure 9121, the bottom end of the liquid discharge inclined surface structure 9121 is a relatively small plane, and the liquid discharge pipe 9122 is provided on the plane, and the plane is connected to the inclined surface, thereby also solving the problem of partially guiding the liquid discharge.

[0161] In one embodiment, as shown in Figures 22 to 24, the tank body 911 includes a bottom shell 9112 and an upper cover 9113, a water flow path 91121 is provided in the bottom shell 9112, an open end is provided in the bottom shell 9112, and the upper cover 9113 is provided to cover the open end of the bottom shell 9112.

[0162] Here, the bottom shell 9112 is a housing structure, the internal cavity of the bottom shell 9112 provides a storage space for the cleaning liquid, and the top cover 9113 is provided to cover the open end of the bottom shell 9112, which serves to seal the open end of the bottom shell 9112, thereby preventing the cleaning liquid from leaking from the bottom shell 9112.

[0163] In some embodiments, the bottom shell 9112 and the top cover 9113 may adopt an integrally molded structure, and the bottom shell 9112 and the top cover 9113 may be connected by ultrasonic treatment. In this embodiment, the fixing method between the bottom shell 9112 and the top cover 9113 is not limited, as long as the sealing effect between the bottom shell 9112 and the top cover 9113 can be ensured to prevent leakage.

[0164] During normal use of the cleaning device, the effectiveness of the liquid storage box directly affects the supply efficiency of the cleaning liquid, and if the liquid supply efficiency of the liquid storage box is relatively low, it will directly affect the mopping effect. Therefore, as shown in Figures 25 and 26, the liquid discharge slope structure 9121 provided by this embodiment is provided on the bottom wall of the bottom shell 9112, and is configured so that the cleaning liquid in the tank body 911 is discharged through the liquid discharge pipe 9122 connected to the bottom wall of the bottom shell 9112 when the tank body 911 is in an upright state. The normal use means that the cleaning device is performing a cleaning task.

[0165] During normal use of the cleaning device, the tank body 911 is used to supply cleaning liquid to other structures such as the wet cleaning structure 913. At this time, the tank body 911 is in an upright position, i.e., the bottom shell 9112 is located below the upper cover 9113, and the upper cover 9113 is located above the bottom shell 9112. The cavity inside the bottom shell 9112 provides a storage space for the liquid discharge pipe 9122, and the bottom shell 9112 serves to connect to the liquid discharge pipe 9122, allowing the cleaning liquid in the bottom shell 9112 to be discharged through the liquid discharge pipe 9122 and used by structures such as the wet cleaning structure 913.

[0166] Here, as shown in Figures 25 and 26, a liquid outlet water pipe 91122 is provided in the bottom shell 9112, and a liquid outlet connector 123 is provided at the bottom of the liquid discharge groove 91211, and when the tank body 911 is in an upright position, the liquid outlet water pipe 91122 is the liquid discharge piping 9122, and the liquid outlet connector 123 is the liquid discharge connector 11, and a communicating hole is provided in the liquid outlet connector 123.

[0167] Specifically, a liquid discharge inclined surface structure 9121 is provided on the bottom wall of the bottom shell 9112, and the height difference between a first end of the liquid discharge inclined surface structure 9121 remote from the liquid outlet water pipe 91122 and a second end of the liquid discharge inclined surface structure 9121 close to the liquid outlet water pipe 91122 is greater than 1 mm, and there is a significant difference in height between the two ends of the liquid discharge inclined surface structure 9121, which serves to guide the cleaning liquid in the tank body 911. A liquid discharge groove 91211 is provided at the bottom end of the liquid discharge inclined surface structure 9121, and the height of the bottom of the liquid discharge groove 91211 is lower than the height of the bottom end of the liquid discharge inclined surface structure 9121, and in this state the groove bottom of the liquid discharge groove 91211 is at the lowest position when the tank body 911 is upright, and the cleaning liquid in the tank body 911 is guided into the liquid discharge groove 91211 via the liquid discharge inclined surface structure 9121, and the liquid discharge groove 91211 collects the cleaning liquid.

[0168] At this time, the liquid outlet connector 123 is in a position where the liquid outlet water pipe 91122 sucks up the cleaning liquid, and the cleaning liquid in the liquid discharge groove 91211 enters the liquid inlet body outlet connector 123 through the communicating hole of the liquid outlet connector 123 and is discharged through the liquid outlet water pipe 91122, so that when the tank body 911 is in an upright position during normal use, the cleaning liquid in the tank body 911 can be discharged to the maximum extent.

[0169] When the cleaning device breaks down and needs to be repaired or maintained, if the cleaning liquid remaining in the liquid storage box is not completely drained, it will be difficult to return it to the factory for maintenance. Therefore, as shown in Figures 25 and 27, the liquid discharge inclined surface structure 9121 provided in this embodiment is provided on the inner wall of the upper cover 9113, and the second end of the liquid discharge pipe 9122 is connected to the water flow path 91121, so that the cleaning liquid in the tank body 911 is discharged through the liquid discharge pipe 9122 and the water flow path 91121 when the tank body 911 is in an inverted state.

[0170] It should be understood that when the cleaning device is returned to the factory for maintenance, the cleaning liquid remaining in the tank body 911 needs to be drained, and at this time the tank body 911 is in an inverted state, i.e., the top cover 9113 is located below the bottom shell 9112, and the bottom shell 9112 is located above the top cover 9113. The cavity surrounded by the top cover 9113 and the bottom shell 9112 provides an accommodation space for the liquid discharge pipe 9122, and the top cover 9113 is connected to the liquid discharge pipe 9122, so that the cleaning liquid remaining in the tank body 911 can be drained through the liquid discharge pipe 9122.

[0171] Here, a liquid inlet water pipe 131 is connected to the upper cover 9113, a liquid inlet connector 132 is provided at the bottom of the liquid discharge groove 91211, and when the tank body 911 is in an inverted state, the liquid inlet water pipe 131 is the liquid discharge piping 9122, the liquid inlet connector 132 is the liquid discharge connector 11, and a communicating hole is provided in the liquid inlet connector 132.

[0172] Specifically, a liquid discharge inclined surface structure 9121 is provided on the inner wall of the upper cover 9113, and when the tank body 911 is in an inverted state, the height difference between the first end of the liquid discharge inclined surface structure 9121, which is far from the liquid inlet water pipe 131, and the second end of the liquid discharge inclined surface structure 9121, which is close to the liquid inlet water pipe 131, is greater than 1 mm, so that there is a significant difference in height between both ends of the liquid discharge inclined surface structure 9121, which plays a role in guiding the cleaning liquid in the tank body 911. A liquid discharge groove 91211 is provided at the bottom end of the liquid discharge inclined surface structure 9121, and the height of the groove bottom of the liquid discharge groove 91211 is lower than the height of the bottom end of the liquid discharge inclined surface structure 9121. At this time, the groove bottom of the liquid discharge groove 91211 is at the lowest position when the tank body 911 is in an inverted state, and the cleaning liquid in the tank body 911 is guided into the liquid discharge groove 91211 through the liquid discharge inclined surface structure 9121, and the liquid discharge groove 91211 realizes the collection of the cleaning liquid.

[0173] At this time, the liquid inlet connector 132 is in a position where the liquid inlet water pipe 131 sucks up the cleaning liquid, and the cleaning liquid in the liquid discharge groove 91211 flows into the liquid inlet connector 132 through the communicating hole of the liquid inlet connector 132, is discharged through the liquid inlet water pipe 131, and finally is sucked up and discharged through the water flow path 91121, so that when the tank body 911 is in an inverted state, the cleaning liquid remaining in the tank body 911 can be discharged to the maximum extent possible.

[0174] In one embodiment, as shown in Figures 25 to 27, a liquid discharge inclined surface structure 9121 is provided on the bottom wall of the bottom shell 9112 and the inner wall of the upper cover 9113, and the cleaning liquid in the tank body 911 is configured to be discharged through a liquid discharge pipe 9122 connected to the bottom wall of the bottom shell 9112 when the tank body 911 is in an upright position, and the cleaning liquid in the tank body 911 is configured to be discharged through a water flow path 91121 via a liquid discharge pipe 9122 connected to the inner wall of the upper cover 9113 when the tank body 911 is in an inverted position.

[0175] In this way, when the tank body 911 is in an upright position for normal use and when the tank body 911 is in an inverted position for repair, the tank body 911 can completely discharge the cleaning liquid, and the liquid discharge inclined surface structure 9121 is provided on the bottom wall of the bottom shell 9112 and the inner wall of the upper cover 9113, and the liquid discharge inclined surface structure 9121 can be used to discharge the cleaning liquid remaining in the tank body 911 to the maximum extent, improving the cleaning liquid discharge efficiency and facilitating after-sales maintenance.

[0176] In some embodiments, when the cleaning device is in a working state performing a cleaning task, the cleaning device is in an upright state, and the cleaning base station supplies cleaning liquid to the liquid storage box through the water flow path 91121 of the bottom shell 9112, and the cleaning liquid flowing in from the water flow path 91121 enters the liquid inlet water pipe 131 and flows into the tank body 911 through the connecting hole provided in the liquid inlet connector 132. At this time, the cleaning liquid falls into the bottom shell 9112 from the position of the upper cover 9113, and the connecting hole of the liquid inlet connector 132 serves to allow the liquid in the liquid inlet water pipe 131 to flow into the water tank 1, so that the wet cleaning structure 913 realizes the mopping process.

[0177] In some embodiments, when the cleaning device is in a maintenance state, the cleaning device is in an inverted position, the upper cover 9113 is positioned below the bottom shell 9112, and the cleaning liquid in the tank body 911 is guided to the liquid discharge groove 91211 through the liquid discharge inclined surface structure 9121 provided on the inner wall of the upper cover 9113, and under the suction action of external force, the cleaning liquid enters the liquid inlet water pipe 131 through the connecting hole of the liquid inlet connector 132 and is sucked out to the outside of the tank body 911 through the water flow path 91121.

[0178] It should be noted that the setting of the cleaning device, i.e., discharging the cleaning liquid with the tank body 911 in an inverted position, is such that the speed at which the cleaning liquid is discharged is slow when the tank body 911 is set upright to perform a cleaning task, but by setting the tank body 911 in an inverted position and discharging the cleaning liquid to the outside via the water flow path 91121, it is possible to utilize the strong suction force characteristics of the cleaning base station to expedite the discharge of the cleaning liquid. It should be noted that it is not that maintenance cannot be performed unless the tank body 911 is in an inverted position, but rather that it is more advantageous for the cleaning liquid to be discharged when the tank body 911 is in an inverted position.

[0179] It should be understood that the flow path of the cleaning liquid in the liquid inlet pipe 131 and the communicating hole and the realization of its main function are different when the tank body 911 is in different states, upright and inverted. When the tank body 911 is in an upright state for normal use, the liquid inlet pipe 131 and the communicating hole mainly serve to inject the cleaning liquid supplied by the cleaning base station into the tank body 911, and when the tank body 911 is in an inverted state, the liquid inlet pipe 131 and the communicating hole mainly serve to discharge the cleaning liquid in the tank body 911 to the outside of the tank body 911, which essentially serves to discharge the liquid.

[0180] This embodiment further provides a cleaning device, which includes a cleaning device reservoir, where the cleaning device is specifically a sweeping cleaning robot with wet cleaning function.

[0181] In the cleaning device provided in this embodiment, a tank body 911 is used to store cleaning liquid, and a liquid discharge structure 912 is provided in the tank body 911, and a liquid discharge inclined surface structure 9121 of the liquid discharge structure 912 is used to maximize the discharge of cleaning liquid from the tank body 911. During actual use, the liquid discharge inclined surface structure 9121 is at least partially inclined relative to the horizontal plane, and the cleaning liquid in the tank body 911 flows from the liquid discharge inclined surface structure 9121 to the bottom end of the liquid discharge inclined surface structure 9121 under the effect of gravity. A first end of a liquid discharge pipe 9122 is connected to the bottom end of the liquid discharge inclined surface structure 9121, and the first end directly receives the cleaning liquid at the bottom end of the liquid discharge inclined surface structure 9121 and serves to discharge the cleaning liquid to the liquid discharge pipe 9122. A liquid discharge port is provided at a second end of the liquid discharge pipe 9122, and the liquid discharge port is used to discharge the cleaning liquid in the liquid discharge pipe 9122 to the outside of the tank body 911. In this way, the liquid discharge inclined surface structure 9121 and the liquid discharge pipe 9122 work together to increase the speed at which the cleaning liquid is discharged, which is highly efficient and advantageous for thoroughly discharging the cleaning liquid from the tank body 911.

[0182] In one embodiment, as shown in FIGS. 25 to 27, the cleaning apparatus further comprises a wet cleaning structure 913, and the reservoir box is used to supply cleaning liquid to the wet cleaning structure 913.

[0183] Here, the wet cleaning structure 913 may be a mop cloth structure or a roller brush structure, which has a water-absorbing material such as cotton, and can be driven to make the mop cloth structure reciprocate or rotate, or make the roller brush structure roll, so that the floor surface to be cleaned is wet cleaned. The liquid storage box supplies cleaning liquid to the wet cleaning structure 913, so that the wet cleaning structure 913 can realize the function of wet mopping the floor.

[0184] In one embodiment, the cleaning apparatus further comprises a transport pipe 914 , a first end of the transport pipe 914 communicating with the liquid outlet of the liquid discharge pipe 9122 , and a second end of the transport pipe 914 connected to the wet cleaning structure 913 .

[0185] The first end of the transport pipe 914 is connected to the liquid discharge port of the liquid discharge pipe 9122, and the second end of the transport pipe 914 is connected to the wet cleaning structure 913. The transport pipe 914 serves to realize intermediate communication between the liquid discharge pipe 9122 and the wet cleaning structure 913, so that the cleaning liquid flowing from the liquid discharge pipe 9122 flows to the wet cleaning structure 913 through the transport pipe 914, thereby realizing the transportation process of the cleaning liquid in the tank body 911 and achieving the purpose of supplying the cleaning liquid to the wet cleaning structure 913.

[0186] In some embodiments, a transport connector 133 is provided on the side of the top cover 9113 facing the bottom shell 9112, a first end of the transport connector 133 is connected to the liquid discharge pipe 9122 (i.e., the liquid outlet water pipe 91122), and a second end of the transport connector 133 is connected to the transport pipe 914, and the transport connector 133 ensures that the relative positions of the transport pipe 914 and the liquid discharge pipe 9122 are fixed while also realizing communication between the transport pipe 914 and the liquid discharge pipe 9122.

[0187] This embodiment provides a cleaning apparatus water tank applicable to a cleaning apparatus, where the cleaning apparatus may be a cleaning apparatus such as a sweeping robot or a mop machine, or may be other types of cleaning apparatus such as a floor scrubber. As shown in Fig. 28 , the cleaning apparatus water tank includes a tank body 921, a liquid inlet pipe 922, and a water inlet valve 923. The liquid inlet pipe 922 is disposed in the tank body 921, and a liquid inlet port 9221 is disposed at a first end of the liquid inlet pipe 922. The water inlet valve 923 is disposed inside the second end of the liquid inlet pipe 922, and the liquid inlet pipe 922 can communicate with the interior cavity of the tank body 921 via the water inlet valve 923. Specifically, by opening or closing the water inlet valve 923, the liquid inlet pipe 922 can selectively communicate with the interior cavity of the tank body 921. The interior cavity of the tank body 921 is used to store a cleaning liquid, which may be water, water with added detergent, or other liquids with cleaning ability.

[0188] In the water tank of the cleaning device provided in this embodiment, a liquid inlet pipe 922 is provided in a tank body 921, which serves to support the entire liquid inlet pipe 922. A liquid inlet port 9221 is provided at a first end of the liquid inlet pipe 922, and a water inlet valve 923 is provided at a second end of the liquid inlet pipe 922. External cleaning liquid can enter the liquid inlet pipe 922 through the liquid inlet port 9221, and the liquid inlet pipe 922 can communicate with the internal cavity of the tank body 921 through the water inlet valve 923. The water inlet valve 923 is used to open and close the liquid inlet pipe 922. When it is necessary to add cleaning liquid to tank body 921, water inlet valve 923 is opened, and the cleaning liquid flowing in from liquid inlet 9221 flows into the internal cavity of tank body 921 through liquid inlet pipe 922 and water inlet valve 923, and tank body 921 provides a storage space for the cleaning liquid and provides the water needed for cleaning structures such as mop cloths. When it is necessary to stop adding cleaning liquid to tank body 921, water inlet valve 923 is closed, and water inlet valve 923 serves to block liquid inlet pipe 922, thereby reducing to some extent the risk of the cleaning liquid in tank body 921 flowing back out of tank body 921.

[0189] In particular, a cleaning base station is provided outside the water tank of the cleaning device, and the cleaning base station supplies cleaning liquid to the internal cavity of the tank body 921 through the liquid inlet 9221. A water storage bucket is provided inside the cleaning base station, and the water storage bucket is detachably connected to the cleaning base station, so that a user can remove the water storage bucket from the cleaning base station, fill it with cleaning liquid, and then place the water storage bucket inside the cleaning base station, and the water storage bucket provides the cleaning liquid needed for mopping to the water tank of the cleaning device. Furthermore, the cleaning base station may be directly connected to a water pipe, and water may be supplied to the water storage bucket through the water pipe.

[0190] In the related art, a water inlet valve 200 (shown in Figure 29) is provided on a water inlet nozzle 92100, and when the water tank is filled with water, the water pressure inside the water tank increases. If the material of the water inlet valve 200 is relatively soft, the water inlet valve 200 may deform in a direction away from the water tank, resulting in a situation where water leaks from the water tank.

[0191] To solve this problem, as shown in FIG. 28, the water tank of the cleaning device provided by this embodiment further includes a support structure 924, which is disposed in the liquid inlet pipe 922 and is used to support the water inlet valve 923.

[0192] In the water tank of the cleaning device provided by this embodiment, the support structure 924 is arranged within the liquid inlet pipe 922, which provides an attachment position for the support structure 924, which is used to support the water inlet valve 923. The support structure 924 is used to resist the deformation force of the water inlet valve 923 toward the outside of the tank body 921, preventing the water inlet valve 923 from deforming in a direction away from the tank body 921, thereby reducing the risk of liquid leakage from the tank body 921 and improving the user experience.

[0193] In one embodiment, the water inlet valve 923 is a one-way valve that allows the cleaning liquid flowing in through the liquid inlet 9221 to flow in one direction into the internal cavity of the tank body 921 .

[0194] The water inlet valve 923 may be a one-way valve, which serves to restrict the flow direction of the cleaning liquid, so that the cleaning liquid flowing from the cleaning base station flows into the internal cavity of the tank body 921 through the water inlet valve 923, but the cleaning liquid in the internal cavity of the tank body 921 cannot return to the cleaning base station through the water inlet valve 923, which can to some extent prevent the cleaning liquid in the water tank of the cleaning device from returning to the outside of the water tank and reduce the risk of liquid leakage from the water tank of the cleaning device.

[0195] In one embodiment, as shown in Figures 30 and 31, the outer shape of the water inlet valve 923 is an approximately cylindrical structure, and the water inlet valve 923 specifically includes a central portion 9231, a fixed portion 9232, and an annular portion 33, wherein a valve port is provided in the central portion 9231 and configured to be selectively opened and closed, the fixed portion 9232 is provided around the periphery of the central portion 9231, and the annular portion 33 is provided between the central portion 9231 and the fixed portion 9232.

[0196] Here, fixed part 9232 is provided within liquid inlet tube 922 and surrounds center part 9231, and fixed part 9232 protects center part 9231 while also serving to mount and secure water inlet valve 923. A valve port is provided in center part 9231, and the valve port is configured to be selectively opened and closed to allow or block the flow of cleaning liquid within liquid inlet tube 922. Annular part 33 is provided between center part 9231 and fixed part 9232, and serves as an intermediate connection between center part 9231 and fixed part 9232, forming an integrated structure.

[0197] Specifically, the central portion 9231 has an approximately circular sheet structure, and a gap 311 is provided in the central portion 9231. The gap 311 has a cross-shaped structure, dividing the central portion 9231 into four units 312. When there is no cleaning liquid passing through the gap 311, the central portion 9231 resembles a sealed structure, and at this time, the valve port is in a closed state. When the cleaning liquid from the external cleaning base station flows into the water inlet valve 923 through the liquid inlet pipe 922, there is a pressure difference between the two ends of the liquid inlet pipe 922, and the cleaning liquid can break through the gap 311, so that the four units 312 expand to form through-holes for the cleaning liquid to pass through. At this time, the annular portion 33 serves to connect the units 312, and the valve port is in an open state, allowing the cleaning liquid in the cleaning base station to be transported to the internal cavity of the tank body 921 through the valve port.

[0198] In addition, since the gap 311 has a cross-shaped structure, the water inlet valve 923 is also called a cross valve. In this embodiment, the shape and structure of the gap 311 is not limited, and the gap 311 may have a U-shaped structure, etc., as long as a through hole is formed between multiple units 312 when a large water pressure hits the gap 311, and it should be understood that all of these are included in the protection scope of this embodiment.

[0199] In particular, the cleaning liquid flowing from the cleaning base station has a large water pressure, which can impact the gap 311 and expand the four elements 312, but the cleaning liquid in the tank body 921 generally does not have a large pressure, so the cleaning liquid in the tank body 921 cannot pass through the gap 311 to expand the elements 312. At the same time, the water inlet valve 923 is generally made of silicone, and if the cleaning liquid does not pass through the water inlet valve 923, the airtightness between the four elements 312 is relatively good, which can reduce the risk of liquid leakage to a certain extent.

[0200] Furthermore, when the tank body 921 is filled with cleaning liquid, the water pressure inside the tank body 921 is relatively high, and since the water inlet valve 923 is made of a silicone material, its texture is relatively soft. Under the action of the high water pressure in the tank body 921, the annular portion 33 of the water inlet valve 923 is depressed and deformed in a direction away from the tank body 921, that is, the annular portion 33 is turned outward, and as the annular portion 33 is turned outward, the units 312 also move in a direction away from the tank body 921. As a result, the four units 312 are not tightly attached, and through holes are formed for the cleaning liquid to pass through, and a small amount of cleaning liquid in the tank body 921 flows in the reverse direction into the tank body 921 via the water inlet valve 923.

[0201] To solve this problem, a support structure 924 supports the side of the annular portion 33 facing the liquid inlet 9221, as shown in Figures 28 and 30.

[0202] When the annular portion 33 has a tendency to curl outward, the support structure 924 supports the side of the annular portion 33 facing the liquid inlet 9221, and therefore the support structure 924 resists the force that causes the annular portion 33 to curl outward. This is equivalent to the support structure 924 occupying the space in which the annular portion 33 moves as it curls outward, and by supporting the annular portion 33, the risk of the annular portion 33 curling outward can be reduced, thereby avoiding liquid leakage from the tank body 921 and achieving the purpose of improving the user's usability.

[0203] It should be understood that since the outer shape of the water inlet valve 923 resembles a cylindrical structure, there are axial and radial directions in the central portion 9231, which is coaxial with the support structure 924, and the support structure 924 further confines the annular portion 33 along the axial outside of the central portion 9231.

[0204] In one embodiment, as shown in FIGS. 28 and 30, the inner wall of the liquid entry tube 922 and the support structure 924 are clamped to either side of the fixing portion 9232 along the radial direction of the central portion 9231 .

[0205] It should be understood that the support structure 924 is located inside the water inlet valve 923, and the inner wall of the liquid inlet tube 922 and the support structure 924 are clamped to both sides of the fixed portion 9232, respectively; that is, by adding a clamping structure at the position of the water inlet valve 923, the positional stability of the water inlet valve 923 along the radial direction of the center portion 9231 is improved under the joint clamping action of the liquid inlet tube 922 and the support structure 924.

[0206] In one embodiment, as shown in Figures 28 and 30, a first flow path 9222 is provided in a liquid inlet tube 922, a liquid inlet port 9221 is provided at a first end of the first flow path 9222, and a water inlet valve 923 and a support structure 924 are provided at a second end of the first flow path 9222.

[0207] Here, the first flow path 9222 provides a transport path for the cleaning liquid flowing from the cleaning base station, and the cleaning liquid enters the first flow path 9222 through the liquid inlet 9221 and is delivered to the water inlet valve 923 under the transport and guiding action of the first flow path 9222. Specifically, the first flow path 9222 resembles a cone structure, with the large opening end of the cone structure facing the cleaning base station and connected to the water inlet of the cleaning base station, and the small opening end of the cone structure facing the water inlet valve 923 and corresponding to the dimensions of the water inlet valve 923.

[0208] In one embodiment, a second flow path 9223 is further provided outside the second end of the liquid inlet tube 922, with a first end of the second flow path 9223 communicating with the first flow path 9222 and a second end of the second flow path 9223 communicating with the internal cavity of the tank body 921. Here, the water inlet valve 923 and a support structure 924 are provided at the connection position between the first flow path 9222 and the second flow path 9223, and the support structure 924 is provided between the water inlet valve 923 and the first flow path 9222.

[0209] It should be understood that the side of the liquid inlet pipe 922 that corresponds to the first flow path 9222 and is closer to the water inlet valve 923 provides a position for the support structure 924, and the support structure 924 is provided on the end face of the liquid inlet pipe 922 that corresponds to the first flow path 9222, thereby realizing support for the water inlet valve 923, and the structure is simple and the production costs are relatively low.

[0210] The support structure 924 is specifically a reinforcing rib, which serves to reinforce the structure of the liquid inlet pipe 922 and has relatively good structural strength.

[0211] In one embodiment, as shown in Figures 28, 30 and 32, the support structure 924 is a support ring, a first end of which is located opposite the first flow path 9222 and communicates with the first flow path 9222, and a second end of which is abutted against the annular portion 33.

[0212] The central hole of the support ring is docked with the small opening end of the first flow path 9222, so that the cleaning solution flowing in from the first flow path 9222 flows into the water inlet valve 923 through the support ring, and the support ring serves as an intermediate connection between the first flow path 9222 and the water inlet valve 923, and does not hinder the cleaning solution from flowing into the water inlet valve 923. Furthermore, the support ring has an annular structure, is continuous, and is installed in contact with the annular portion 33, so that the support ring can provide support for the annular portion 33. Therefore, the support ring has the dual functions of circulating the cleaning solution and supporting the water inlet valve 923.

[0213] In some other embodiments, the support structure 924 is at least one support protrusion, the support protrusion abutting the annular portion 33, and two adjacent support protrusions are spaced apart at the second end of the first flow path 9222.

[0214] Here, the number of support protrusions may be one or more. When there is one support protrusion, the annular portion 33 is supported by a separately provided support protrusion, and the support protrusion essentially plays the role of a support rod. When there are multiple support protrusions, the multiple support protrusions are spaced apart and uniformly arranged around the circumferential direction of the water inlet valve 923. Compared with when the support ring has a continuous structure, the support structure 924 in this case has a discontinuous intermittent structure, which can save raw materials and has a relatively low production cost.

[0215] In one embodiment, as shown in Figures 28 and 33, the water tank of the cleaning device further includes a fixing member 925, which is connected to the tank body 921 and is provided on the side away from the support structure 924 of the water inlet valve 923 to fix the water inlet valve 923.

[0216] Here, the fixing member 925 is also called a fixing cover, and is provided on the inner wall of the tank body 921, which provides an installation position for the fixing member 925. The fixing member 925 serves to limit and fix the water inlet valve 923, thereby preventing the water inlet valve 923 from coming off the liquid inlet pipe 922.

[0217] In particular, a first connecting hole is provided in the fixing member 925, a second connecting hole is provided in the tank body 921 corresponding to the first connecting hole, and a bolt is provided through the first connecting hole and the second connecting hole to fix the fixing member 925 in the tank body 921. Of course, in some other embodiments, the fixing member 925 and the tank body 921 may be connected by a connecting method such as locking.

[0218] In one embodiment, the fixed member 925 is at least partially disposed within the second flow path 9223, and a third flow path 9251 is disposed within the fixed member 925, a first end of the third flow path 9251 communicates with the second flow path 9223, and a second end of the third flow path 9251 communicates with the internal cavity of the tank body 921, with the third flow path 9251 serving as an intermediate communication. The liquid inlet pipe 922 communicates with the internal cavity of the tank body 921 via the third flow path 9251 of the fixed member 925, and the fixed member 925 also serves as an intermediate communication, allowing the cleaning liquid flowing from the liquid inlet pipe 922 to flow into the internal cavity of the tank body 921 via the third flow path 9251 of the fixed member 925.

[0219] It should be understood that along the axial direction of the center portion 9231 of the water inlet valve 923, the first end of the fixed portion 9232 of the water inlet valve 923 abuts against the end face corresponding to the first flow path 9222 of the liquid inlet pipe 922, and the second end of the water inlet valve 923 abuts against the fixed member 925, thereby realizing restriction of the water inlet valve 923 along the axial direction of the center portion 9231 and at the same time improving the positional stability of the water inlet valve 923.

[0220] In particular, the side surfaces of fixing member 925 and fixing portion 9232 facing each other are inclined, which increases the contact area between fixing member 925 and fixing portion 9232 and improves the contact effect of fixing member 925 against fixing portion 9232.

[0221] 34 and 35 , the water tank of the cleaning apparatus further includes a liquid inlet pipe 926, which is disposed within the tank body 921, with a first end of the liquid inlet pipe 926 communicating with the third flow path 9251 of the fixing member 925 and a second end of the liquid inlet pipe 926 communicating with the internal cavity of the tank body 921. Here, the fixing member 925 functions as a piping connector, and the cleaning liquid flowing from the third flow path 9251 of the fixing member 925 is transported to the internal cavity of the tank body 921 via the liquid inlet pipe 926.

[0222] 36 and 37, the tank body 921 includes a bottom shell 9211 and an upper cover 9212, the bottom shell 9211 has an open end, and the upper cover 9212 is disposed to cover the open end of the bottom shell 9211. Here, the second end of the liquid inlet pipe 926 is connected to the upper cover 9212.

[0223] Here, the liquid inlet pipe 926 can be disposed within the bottom shell 9211 through the open end of the bottom shell 9211, and the bottom shell 9211 provides a storage space for the liquid inlet pipe 926. The top cover 9212 is disposed to cover the open end of the bottom shell 9211, and the bottom shell 9211 and the top cover 9212 are closed together as a single unit. A first end of the liquid inlet pipe 926 communicates with the third flow path 9251 of the fixing member 925, and a second end of the liquid inlet pipe 926 is connected to the top cover 9212. The liquid inlet pipe 926 extends the water inlet to the top of the tank body 921. When liquid is injected into the tank body 921 by the cleaning base station, the cleaning liquid can drop from the top cover 9212 into the bottom shell 9211.

[0224] In one embodiment, the top cover 9212 further includes a connector 92121, which is provided on the side of the top cover 9212 facing the bottom shell 9211, and which is connected to the liquid inlet pipe 926, and which has a communication hole provided in the connector 92121, which is connected to the internal cavity of the tank body 921.

[0225] After the cleaning liquid in the liquid inlet pipe 926 is transported to the connector 92121, the communication holes of the connector 92121 function as a nozzle shower, spraying the cleaning liquid into the tank body 921 from above, and the communication holes of the connector 92121 ensure the supply of cleaning liquid within the tank body 921. Furthermore, since there is usually a certain height difference between the level of the cleaning liquid in the bottom shell 9211 and the upper cover 9212, when the cleaning base station stops supplying cleaning liquid to the water tank, the cleaning liquid in the water tank will not enter the liquid inlet pipe 926 through the communication holes of the connector 92121, which serves to prevent back siphoning of the water flow and further reduces the risk of liquid leakage.

[0226] This embodiment further provides a cleaning device comprising the water tank of the cleaning device described above.

[0227] This embodiment further provides a cleaning device equipped with a cleaning device water tank, the cleaning device water tank being used to store cleaning liquid, the support structure 924 of the cleaning device water tank being able to resist the deformation force of the water inlet valve 923, reducing the risk of liquid leakage from the cleaning device water tank, and the cleaning device water tank being able to stably and reliably supply the cleaning liquid required for components such as wet cleaning structures, improving the user experience.

[0228] The liquid inlet pipe 922 of the cleaning device's water tank supplies cleaning liquid from the external cleaning base station to the tank body 921, but after the cleaning device's water tank is refilled with cleaning liquid and removed from the cleaning base station, a small amount of cleaning liquid remains in the cleaning device's water tank, which makes it difficult for the user to use.

[0229] To solve this problem, as shown in FIG. 38, a drain hole 92111 is provided in the tank body 921 of the water tank of the cleaning device, and the drain hole 92111 is provided corresponding to the liquid inlet 9221, and the drain hole 92111 is used to drain the cleaning liquid flowing from the liquid inlet 9221.

[0230] A drain hole 92111 is provided in the tank body 921, and the drain hole 92111 is provided corresponding to the liquid inlet 9221, which corresponds to the drain hole 92111 being provided in the residual water area of ​​the water tank of the cleaning device. After the cleaning device is refilled with water and removed from the cleaning base station, if a small amount of cleaning liquid remains in the water tank of the cleaning device, the remaining cleaning liquid can flow out through the drain hole 92111, preventing the cleaning liquid from remaining and improving the drying of the residual water area.

[0231] In one embodiment, the cleaning apparatus further comprises a wet cleaning structure 927 , and the tank body 921 is used to supply water to the wet cleaning structure 927 .

[0232] Here, the wet cleaning structure 927 may be a mop cloth structure or a roller brush structure, which has a water-absorbing material such as cotton, and the mop cloth structure is driven to reciprocate or rotate, or the roller brush structure is driven to roll, thereby wet cleaning the floor surface to be cleaned. The tank body 921 is used to supply water to the wet cleaning structure 927, and the wet cleaning structure 927 can achieve a mopping function.

[0233] In one embodiment, the drain holes 92111 are located above the wet cleaning structure 927 so that cleaning liquid flowing from the liquid inlet 9221 enters the wet cleaning structure 927 via the drain holes 92111.

[0234] Because the drain hole 92111 is located above the wet cleaning structure 927, the remaining cleaning liquid can flow through the drain hole 92111 into the wet cleaning structure 927 below, avoiding waste of cleaning liquid while also realizing effective reuse of the cleaning liquid, supplying the wet cleaning structure 927 with the cleaning liquid it needs, and solving the problem of liquid residue caused by liquid replenishment in the cleaning device, greatly improving the user experience of the cleaning device and reducing the repair rate of the cleaning device.

[0235] Cleaning devices such as sweeping robots generally have functions such as sweeping, dust collection, and mopping, and the mopping function is achieved by supplying water from a water tank to a mop cloth. Because the amount of water in the water tank is limited, the water tank may run out of water during the mopping process. If the cleaning device performs mopping in an empty state, the mopping effect will be poor, making it difficult to achieve the desired cleaning effect. Furthermore, the structure of the sweeping robot itself may be damaged, reducing the mopping function of the sweeping robot.

[0236] To solve this problem, as shown in Fig. 39, this embodiment provides a liquid level detection structure for a water tank of a cleaning device, which is applied to a cleaning device. The cleaning device may be a cleaning device such as a sweeping cleaning robot or a mop machine, or may be another type of cleaning device such as a floor scrubber. The liquid level detection structure for the water tank of the cleaning device includes a float assembly 932 and a sensing member 934. The float assembly 932 is disposed in a water tank 93100 and configured to move in response to changes in the liquid level in the water tank 93100. The sensing member 934 is disposed on the water tank 93100 and configured to generate a sensing signal in response to the relative movement of the float assembly 932. The sensing member 934 may be disposed on the top cover of the water tank 93100 or on the bottom of the water tank 93100. Here, the water tank 93100 is used to store cleaning liquid, which may be water, water with added detergent, or other liquids with cleaning ability.

[0237] In the liquid level detection structure for the water tank of the cleaning device provided by this embodiment, the float assembly 932 is capable of floating within the water tank 93100, and is movable in response to changes in the liquid level within the water tank 93100, moving the float assembly 932 closer to or farther from the sensing member 934, which generates a sensing signal in response to the relative movement of the float assembly 932, thereby detecting the liquid level in the water tank 93100. The float assembly 932 and the sensing member 934 are arranged opposite each other vertically, and the sensing member 934 may be arranged on the water tank cover directly above the float assembly 932, or on the bottom of the water tank 93100 directly below the float assembly 932.

[0238] Based on the strength of the sensing signal generated by the sensing member 934, the distance between the floating assembly 932 and the sensing member 934 can be determined, and thereby the liquid level in the water tank 93100 can be determined.

[0239] It should be understood that the sensing signal generated by the sensing member 934 is not a signal having only two states, open and closed, but a linear signal that gradually becomes stronger or weaker according to the change in the distance of the floating assembly 932. The signal strength of the sensing signal has a linear relationship with a one-to-one correspondence with the distance between the sensing member 934 and the floating assembly 932, so that the corresponding distance can be obtained based on the signal strength, and thus an accurate value of the liquid level can be obtained.

[0240] Under the action of liquid buoyancy in the water tank 93100, the floating assembly 932 can move up and down along a first direction, which may be the height direction of the water tank 93100, and if the floating assembly 932 resembles a cylindrical structure, the first direction may specifically be the axial direction of the floating assembly 932.

[0241] In one embodiment, as shown in FIG. 39, the liquid level detection structure of the water tank of the cleaning device further includes a limiting structure 931, wherein the limiting structure 931 is provided in the water tank 93100, and the floating assembly 932 is provided in the limiting structure 931, and the limiting structure 931 is used to limit the floating assembly 932.

[0242] Here, the floating assembly 932 is disposed within the limiting structure 931, which serves to limit the floating assembly 932 and surround the floating assembly 932, thereby preventing the floating assembly 932 from floating offset over a large range along the horizontal direction during the floating process, limiting the range of movement of the floating assembly 932, and improving the accuracy of liquid level detection.

[0243] Furthermore, the limiting structure 931 is installed in the water tank 93100, and the limiting structure 931 is fixedly connected to the bottom of the water tank 93100, which may cause the connection strength to be insufficient. During long-term use, the limiting structure 931 may tilt. If the limiting structure 931 tilts toward the floating assembly 932, the limiting structure 931 may catch the floating assembly 932, which may affect the accuracy of the detected liquid level. In this case, the water tank 93100 is actually full, but the sensing member 934 and the floating assembly 932 Therefore, if the water tank 93100 is detected as not full, cleaning liquid continues to be poured into the water tank 93100, causing the cleaning liquid in the water tank 93100 to overflow, which is a wasteful situation; if the water tank 93100 is actually low on liquid, the sensing member 934 and floating assembly 932 may detect that the water tank 93100 is full, and the water tank 93100 will not be immediately replenished with cleaning liquid, which may result in the cleaning liquid in the water tank 93100 running out during the sweeping or mopping process. If the cleaning device performs sweeping or mopping operations without liquid, it may damage the structure of the cleaning device itself, increase the probability of malfunction and production costs, deteriorate the sweeping or mopping function of the cleaning device, and negatively affect the user's experience. When the limiting structure 931 tilts away from the floating assembly 932, the limiting ability of the limiting structure 931 decreases, resulting in the floating assembly 932 not moving up and down along the first direction, causing a horizontal offset, increasing the distance between the floating assembly 932 and the sensing member 934, and potentially resulting in inaccurate liquid level measurements.

[0244] To solve this problem, as shown in FIGS. 39 and 40, a reinforcing structure 933 is provided on the side of the limiting structure 931 provided by this embodiment that is remote from the floating assembly 932.

[0245] A reinforcing structure 933 is provided on the side of the limiting structure 931 away from the floating assembly 932, i.e., the floating assembly 932 is provided inside the limiting structure 931 and the reinforcing structure 933 is provided outside the limiting structure 931, and the reinforcing structure 933 does not interfere with the floating assembly 932, and the reinforcing structure 933 serves to reinforce the structure of the limiting structure 931, thereby increasing the structural stability of the limiting structure 931, preventing the limiting structure 931 from tilting, reducing the risk of the floating assembly 932 being caught by the limiting structure 931, and avoiding inaccurate liquid level measurement.

[0246] The reinforcing structure 933 may be connected to the outside of the limiting structure 931 and the bottom surface of the water tank 93100, which corresponds to increasing the connection area between the limiting structure 931 and the bottom wall 102 of the water tank 93100, thereby enhancing the fixing effect of the limiting structure 931 to the bottom surface of the water tank 93100 and reducing the risk of the limiting structure 931 tilting.

[0247] In particular, the limiting structure 931 is adapted to the shape and structure of the floating assembly 932. The outer shape of the floating assembly 932 may be a cylindrical structure, the outer shape of the limiting structure 931 may be set to a cylindrical structure, the outer shape of the floating assembly 932 may also be a rectangular parallelepiped structure, and the cross-sectional outer shape of the limiting structure 931 may be set to a rectangular structure. This embodiment does not limit the outer shapes and structures of the floating assembly 932 and the limiting structure 931, and these can be adjusted according to actual production conditions. As long as the shape and structure of the limiting structure 931 and the floating assembly 932 are adapted, that is, as long as the limiting structure 931 can play the role of adapting to the shape of the floating assembly 932, it shall be within the protection scope of this embodiment.

[0248] In one embodiment, as shown in Figures 40 and 41, the limiting structure 931 includes a plurality of surrounding members 9311 that are arranged around and limit the floating assembly 932, and at least one of the surrounding members 9311 is provided with a reinforcing structure 933.

[0249] Here, the limiting structure 931 is a separate structure, and the multiple enclosing members 9311 of the limiting structure 931 are arranged around the floating assembly 932 to restrict the floating assembly 932, which corresponds to the multiple independently arranged enclosing members 9311 enclosing the floating assembly 932 inside, and the multiple independently arranged enclosing members 9311 alone can restrict the floating assembly 932. Under the cooperative action of the multiple enclosing members 9311, the floating assembly 932 is prevented from moving over a large range. The reinforcing structure 933 can increase the structural strength of at least one enclosing member 9311.

[0250] In one embodiment, as shown in Figures 40 and 41, the limiting structure 931 further includes a portion of the water tank sidewall, which is provided around and limits the floating assembly 932 together with a plurality of surrounding members 9311.

[0251] Here, the portion of the water tank side wall is specifically a portion of the structure of the side wall 101 of the water tank 93100, and the limiting structure 931 includes a portion of the structure of the side wall 101 in addition to the surrounding member 9311. The multiple surrounding members 9311 together with a portion of the water tank side wall form the limiting structure 931, which achieves a good connection effect between the water tank side wall and the bottom surface of the water tank 93100, making it less likely to deform. By using a portion of the structure of the water tank side wall as part of the limiting structure 931, the risk of the limiting structure 931 tilting can be reduced.

[0252] The position of the limiting structure 931 can be freely and flexibly set, and the limiting structure 931 may be located at an edge position close to the water tank 93100 or at a central position of the water tank 93100. When the limiting structure 931 is located at an edge position close to the water tank 93100, the multiple enclosing members 9311 and a portion of the water tank side wall are spaced apart, i.e., the enclosing members 9311 do not contact the side wall 101 of the water tank 93100. In this case, the multiple spaced apart enclosing members 9311, together with a portion of the water tank side wall, enclose a substantially annular structure, and the floating assembly 932 is located within the annular structure, thereby realizing the restriction and enclosing of the limiting structure 931 relative to the floating assembly 932. At least one enclosing member 9311 may be further connected to a portion of the water tank side wall, and the side wall 101 of the water tank 93100 serves to support and fix the enclosing member 9311, thereby improving the stability of the limiting structure 931. When the limiting structure 931 is provided at a central position of the water tank 93100, it is not necessary to configure the limiting structure with the help of the water tank side wall, and multiple surrounding members 9311 can be provided around the floating assembly 932.

[0253] In one embodiment, as shown in FIG. 40, a portion of the water tank side wall is recessed in a direction away from the floating assembly 932 to correspond to the floating assembly 932 to form a recess 9313, which together with a plurality of surrounding members 9311 forms a limiting structure 931.

[0254] Here, the recess 9313 serves to partially accommodate the floating assembly 932, and at the same time, to restrict the floating assembly 932. The recess 9313 forms the restricting structure 931 together with the plurality of surrounding members 9311, which corresponds to using a part of the side wall 101 of the water tank 93100 as the restricting part, thereby saving the raw materials of some of the restricting structure 931 and reducing the production cost.

[0255] It should be noted that the outer shape of the water tank 93100 is an approximately arc-shaped structure, which avoids the possibility of a corner structure injuring the user, and if the outer shape of the floating assembly 932 is a cylindrical structure, the arc-shaped structure of part of the side wall 101 of the water tank 93100 can be used to directly restrict the floating assembly 932, which can be manufactured using materials available on site and has relatively low production costs.

[0256] In one embodiment, as shown in Figures 40 and 41, a guide cavity 142 is formed in the restricting structure 931, the floating assembly 932 is provided in the guide cavity 142, and a water inlet 9312 is provided between two adjacent surrounding members 9311 or between the surrounding member 9311 and a portion of the water tank side wall, and the guide cavity 142 is connected to the internal cavity of the water tank 93100 via the water inlet 9312.

[0257] It should be understood that if the limiting structure 931 is a sealed structure, the floating assembly 932 only characterizes the liquid level in the limiting structure 931, not the liquid level in the water tank 93100. In the case of a separate limiting structure 931, when two adjacent enclosing members 9311 are spaced apart and do not contact each other, a gap exists between the two adjacent enclosing members 9311, which can be used as a water inlet 9312, the guide cavity 142 communicates with the internal cavity of the water tank 93100 through the water inlet 9312, and the cleaning liquid in the water tank 93100 enters the guide cavity 142 through the water inlet 9312, that is, the limiting structure 931 is not a sealed structure, and the liquid level detected by the floating assembly 932 corresponds not only to the liquid level in the guide cavity 142, but also to the liquid level in the water tank 93100.

[0258] In some other embodiments, the limiting structure 931 may be an integral structure, and this embodiment does not limit the specific form of the limiting structure 931, which can be adjusted according to actual production conditions. When the limiting structure 931 is an integral structure, the bottom of the limiting structure 931 is the contact part between the limiting structure 931 and the water tank 93100. Therefore, a water inlet 9312 can be opened at the bottom of the limiting structure 931 to allow the cleaning liquid in the water tank 93100 to flow into the guide cavity 142 of the limiting structure 931 through the water inlet 9312, and the liquid level in the guide cavity 142 is the same as the liquid level in the water tank 93100.

[0259] In one embodiment, as shown in Figures 41 and 42, the reinforcing structure 933 includes at least one reinforcing rib 9331, i.e., multiple reinforcing ribs 9331 are provided on the limiting structure 931 and serve to reinforce the strength of the structure surrounding the limiting structure 931.

[0260] In one embodiment, the number of surrounding members 9311 provided is specifically two, and the two surrounding members 9311 are respectively provided on both sides of the recessed portion 9313. The structures of the two surrounding members 9311 may be the same or different, and the arc lengths of the two surrounding members 9311 relative to the center of the floating assembly 932 may be the same or different. In this embodiment, the number of surrounding members 9311 is not limited and can be adjusted according to actual production conditions.

[0261] In one embodiment, the enclosing member 9311 includes a first enclosing member 93111 and a second enclosing member 112, where the first enclosing member 93111 is connected to the side wall 101 of the water tank 93100 and the second enclosing member 112 is spaced apart from the side wall 101 of the water tank 93100.

[0262] The first enclosing member 93111 is connected to the side wall 101 of the water tank 93100, and in this case, the bottom of the first enclosing member 93111 and the side closest to the side wall 101 of the water tank 93100 are both connected to the water tank 93100, thereby improving the fixing effect of the first enclosing member 93111. The second enclosing member 112 is spaced apart from the side wall 101 of the water tank 93100, so that only the bottom of the second enclosing member 112 is connected to the water tank 93100. At this time, the first side of the first enclosing member 93111 is connected to the side wall 101 of the water tank 93100, there is a water inlet 9312 between the second side of the first enclosing member 93111 and the second enclosing member 112, there is a water inlet 9312 between the side of the second enclosing member 112 away from the first enclosing member 93111 and the side wall 101 of the water tank 93100, and the guide cavity 142 of the limiting structure 931 is connected to the water tank 93100 through the two water inlets 9312, thereby maintaining the consistency of the liquid levels in the internal cavity of the water tank 93100 and the guide cavity 142.

[0263] In one embodiment, as shown in FIGS. 41 and 42, the number of reinforcing ribs 9331 provided corresponding to the first enclosing member 93111 is less than the number of reinforcing ribs 9331 provided corresponding to the second enclosing member 112.

[0264] It should be understood that since the first enclosing member 93111 is connected to the side wall 101 of the water tank 93100 and the second enclosing member 112 is not connected to the side wall 101 of the water tank 93100, the connection strength between the second enclosing member 112 and the water tank 93100 is smaller than the connection strength between the first enclosing member 93111 and the water tank 93100. By setting the number of reinforcing ribs 9331 to be greater than the number corresponding to the first enclosing member 93111, the strength of the connection between the second enclosing member 112 and the water tank 93100 can be reinforced, and the first enclosing member 93111 and the second enclosing member 112 will be in a similar upright position relative to the water tank 93100, thereby improving the positional stability of the first enclosing member 93111 and the second enclosing member 112 and reducing the risk of the floating assembly 932 getting caught due to the tilting of the limiting structure 931.

[0265] In one embodiment, as shown in Figures 41 and 42, the reinforcing ribs 9331 may be arranged in parallel and spaced apart relation, or may cross each other.

[0266] Here, when the multiple reinforcing ribs 9331 are arranged in parallel with a gap between them, the aesthetic appearance is high and neat, so that the space occupied by the liquid level detection structure of the water tank of the entire cleaning device is small and other components can be easily arranged inside the water tank 93100. When the multiple reinforcing ribs 9331 are arranged crosswise with each other, a reinforcing rib rope is formed, which can resist impact forces from different directions.

[0267] In addition, the multiple reinforcing ribs 9331 may be provided in pairs, with the two reinforcing ribs 9331 in each pair being curved opposite each other, with the curvature directions of the two reinforcing ribs 9331 being opposite to each other and serving to compensate for each other.

[0268] In one embodiment, the limiting structure 931, the reinforcing structure 933, and the water tank 93100 are a one-piece molded structure. The one-piece molded structure reduces the number of parts to be assembled and reduces production costs.

[0269] In one embodiment, as shown in FIGS. 41 and 42, a guide structure 9314 is provided on the side of the limiting structure 931 facing the floating assembly 932, and the guide structure 9314 is used to guide the floating assembly 932.

[0270] A guide structure 9314 is provided on the side of the limiting structure 931 facing the floating assembly 932, and the guide structure 9314 serves to guide and position the floating assembly 932. Under the action of the guide structure 9314, the floating assembly 932 is floatably arranged within the guide cavity 142 of the limiting structure 931 and can move up and down along the first direction.

[0271] Specifically, the guide structure 9314 includes a plurality of engagement claws 141, among which are formed guide cavities 142 for restricting the floating assembly 932. The engagement claws 141 are arranged parallel to one another and extend along a first direction to ensure that the floating assembly 932 moves linearly along the first direction within the guide cavities 142. The engagement claws 141 are evenly spaced and uniformly distributed on the same circumference, so that the engagement claws 141 can evenly surround the outer surface of the floating assembly 932, improving the balance of forces between the engagement claws 141 and the side surfaces of the floating assembly 932 and reducing jamming and tilting of the floating assembly 932. The engaging claw 141 further reduces the contact area between the floating assembly 932 and the limiting structure 931, converting the surface contact between the floating assembly 932 and the limiting structure 931 into line contact between the floating assembly 932 and the engaging claw 141, thereby realizing a guiding effect while maximizing the reduction in the contact area, reducing sliding resistance, reducing the probability of clogging of the floating assembly 932, and improving the accuracy of liquid level detection.

[0272] Here, the number of the engaging claws 141 is at least three, but is not specifically limited and may be determined according to the shape of the floating assembly 932. The principle of three points defining a plane ensures that the floating assembly 932 does not detach from the limiting structure 931. If the floating assembly 932 has a cylindrical structure, only three engaging claws 141 are sufficient to limit the linear movement of the floating assembly 932 along the first direction, and four engaging claws 141 may be used to achieve a more stable effect.

[0273] In one embodiment, the sensing member 934 may be provided at a position corresponding to the guide cavity 142 of the limiting structure 931, so that the sensing signal obtained by the sensing member 934 can reliably reflect the actual liquid level information.

[0274] It should be noted that the type of sensing signal generated by the sensing member 934 provided in this embodiment is not limited, and the sensing signal may be derived from a magnetic field signal. Specifically, the sensing member 934 provided in this embodiment adopts a Hall sensor, which may be installed on the top of the water tank 93100 and located directly above the guide cavity 142.

[0275] As shown in FIG. 43, the floating assembly 932 includes a floating housing 9321 and a permanent magnet 9322, the floating housing 9321 can float according to the liquid level, the permanent magnet 9322 is disposed within the floating housing 9321, and the floating housing 9321 serves to protect the permanent magnet 9322, where the permanent magnet 9322 is a material having a certain magnetic field, and the Hall sensor is an element whose output level is linearly related to the applied magnetic field within a certain range.

[0276] When the liquid level in the water tank 93100 drops, the floating housing 9321 drops along with the liquid level, and the permanent magnet 9322 fixed in the floating housing 9321 gradually moves away from the Hall sensor, the magnetic field strength gradually decreases, and the electrical signal generated by the Hall sensor also gradually decreases. When the electrical signal generated by the Hall sensor reaches a minimum value, it means that the permanent magnet 9322 is almost close to the bottom of the water tank 93100, so it is determined that the water tank 93100 is in a state where there is a shortage of cleaning liquid, and at this time, cleaning liquid needs to be supplied to the water tank 93100 in a timely manner.

[0277] As the floating assembly 932 floats and rises with the increase in the liquid level in the water tank 93100, the permanent magnet 9322 gradually approaches the Hall sensor, so that the magnetic field strength continuously increases, and the electrical signal generated by the Hall sensor also continuously increases. When the electrical signal generated by the Hall sensor reaches its maximum value, it means that the permanent magnet 9322 is almost close to the top of the water tank 93100, and it is determined that the water tank 93100 is full of cleaning liquid, and there is no need to supply cleaning liquid to the water tank 93100 at this time.

[0278] It should be understood that when the Hall sensor is installed below the permanent magnet 9322, an increase in the electrical signal generated by the Hall sensor means that the liquid level in the water tank 93100 has decreased, and a decrease in the electrical signal generated by the Hall sensor means that the liquid level in the water tank 93100 has increased, and since the principle is similar, detailed explanations will not be repeated.

[0279] In one embodiment, the liquid level detection structure of the cleaning device water tank further includes a control board, which is electrically connected to the Hall sensor and obtains a corresponding liquid level value according to changes in the strength of the electrical signal, thereby realizing quantitative detection of the liquid level. Although the Hall sensor is used in this embodiment, it is not intended to limit the present disclosure, and it should be understood that methods by those skilled in the art that use other types of signal detection elements, such as light waves and acoustic waves, are all within the scope of protection of the present disclosure.

[0280] This embodiment further provides a cleaning apparatus, which includes a water tank 93100 and the above-mentioned liquid level detection structure for the water tank of the cleaning apparatus, and the liquid level detection structure for the water tank of the cleaning apparatus is provided in the water tank 93100 and is used to detect the liquid level of the water tank 93100. Here, the cleaning apparatus may specifically be a cleaning apparatus such as a sweeping cleaning robot or a mop machine, or may be other types of cleaning apparatus such as a floor scrubber.

[0281] The cleaning device provided in this embodiment can detect the liquid level information of the water tank 93100 through the liquid level detection structure of the cleaning device's water tank, so that the cleaning and mopping operations can be performed more rationally, resulting in a more intelligent cleaning device and improving the user experience.

[0282] In one embodiment, the cleaning apparatus further includes a display module and a presentation module, which are electrically connected to the control board, where the display module is used to display the water level information and the presentation module is used to transmit the presentation information to a user, and the control board receives the sensing signal from the sensing member 934, calculates corresponding water level information based on changes in the intensity of the sensing signal, and transmits the water level information to the display module for viewing by a user.

[0283] When the water level is detected to be relatively low, the cleaning operation can be intelligently performed, for example, the remaining cleaning time can be estimated from the remaining water amount to shorten the cleaning stroke, the cleaning device can be controlled to stop cleaning, or the cleaning device can be controlled to return to the cleaning base station for water replenishment, and at the same time, the presentation module can be controlled to issue presentation information to the user.

[0284] In addition, the presentation module may further include an audio device, which is used to emit a presentation sound to present the liquid level change to the user, for example, emitting a voice presentation such as "The liquid level is low, please add more."

[0285] Through the mutual cooperation of the control board, the sensing member 934 and the floating assembly 932, the cleaning device can quantitatively detect the liquid level in the water tank 93100, and intelligently plan the cleaning and mopping path according to the remaining water amount, thereby improving the cleaning and mopping effect. At the same time, the prompting module can prompt the user to add water, so as to avoid the cleaning device idling when there is no cleaning liquid, and extend the service life of the cleaning device.

[0286] This embodiment provides a cleaning device, which may be specifically a cleaning device such as a sweeping robot or a mop machine, or may be other types of cleaning devices such as a floor scrubber, etc. As shown in Fig. 44, the cleaning device includes a sensor 94100 and a sensor mounting structure, and the sensor mounting structure is used to mount the sensor 94100.

[0287] The cleaning device provided in this embodiment can utilize a sensor mounting structure to mount the sensor 94100, thereby improving the ease of mounting the sensor 94100. The sensor 94100 is used to detect the floor surface to be cleaned, allowing the cleaning device to adjust its direction in a timely manner, ensuring that the cleaning device operates smoothly during the sweeping and mopping process.

[0288] Here, the sensor 94100 is specifically a carpet sensor in some embodiments of the present disclosure, and the carpet sensor is used to identify the presence or absence of a carpet, and provide the necessary parameters for the cleaning device.

[0289] It should be understood that in some other embodiments, the sensor 94100 may be an infrared sensor, a water pressure sensor, a power sensor, a dirt level sensor, etc., and the mounting structure and control implementation thereof are similar to those of the carpet sensor, so detailed description will not be repeated here.

[0290] This embodiment further provides a sensor mounting structure, and as shown in Figures 44 and 45, the sensor mounting structure includes a main body 941 and a fixed cover 942, the fixed cover 942 is disposed on the main body 941, and a storage cavity 943 is disposed between the fixed cover 942 and the main body 941, and the storage cavity 943 is used to store a sensor 94100.

[0291] In the sensor mounting structure provided by this embodiment, the main body 941 serves to place the sensor 94100 and the fixed cover 942, and a storage cavity 943 is provided between the main body 941 and the fixed cover 942. The storage cavity 943 provides storage space for the sensor 94100 and also serves to protect the sensor 94100.

[0292] In the related art, both ends of the sensor fixing cover 100' are fixed to the main housing 200' via at least two screws 300' (shown in FIG. 46), and during the process of installing and removing the sensor, the two screws 300' must first be removed and installed sequentially, which makes the assembly and maintenance time of the entire machine relatively long and increases production and maintenance costs.

[0293] To solve this problem, in the sensor mounting structure provided by this embodiment, as shown in Figures 44 and 45, the fixed cover 942 has opposing first and second ends, and a fixed portion is provided on one side of the first end and the main body 941, and a fixed fitting portion fitted into the fixed portion is provided on the other side, and an mounting portion 9423 is provided on the second end of the fixed cover 942, and the mounting portion 9423 is connected to the main body 941 via a fastener.

[0294] In the sensor mounting structure provided in this embodiment, a fixing portion is provided on one of the first end of fixed cover 942 and main body 941, and a fixing mating portion engaged with the fixing portion is provided on the other, so that the first end of fixed cover 942 is fixed to main body 941 through the mutual cooperation of the fixing portion and the fixing mating portion. A mounting portion 9423 is provided on the second end of fixed cover 942, which provides a mounting position for the second end of fixed cover 942 and simultaneously increases the contact area between fixed cover 942 and main body 941, thereby improving the connection stability between fixed cover 942 and main body 941. The mounting portion 9423 is connected to main body 941 via a fastener, so that the second end of fixed cover 942 is fixed to main body 941, and both ends of fixed cover 942 can be fixed to main body 941. The fixed cover 942 can be fixed to the main body 941 with only one fastener, eliminating one fastener and simultaneously saving the assembly and maintenance time of the entire machine, reducing assembly and maintenance costs, and improving production efficiency.

[0295] Here, the attachment portion 9423 is specifically a tab that protrudes along the second edge of the fixed cover 942, and has an outer shape similar to a lug structure.

[0296] In particular, the fastener is specifically a bolt 944, which has a simple structure, is easy to use, and has a relatively low production cost. Specifically, the mounting portion 9423 is provided with a first connecting hole 232, the main body 941 receives a second connecting hole corresponding to the first connecting hole 232, and the bolt 944 is provided passing through the first connecting hole 232 and the second connecting hole, respectively, to fix the fixing cover 942 on the main body 941. At the same time, compared to the related art in which the bolt 944 directly passes through the fixing cover 942, the bolt 944 is prevented from directly damaging the fixing cover 942, and the service life of the fixing cover 942 is extended.

[0297] It should be noted that the fastener provided in this embodiment includes bolt 944, but is not limited thereto, and a fixing member such as a fixing pin may also be selected. It should be understood that this embodiment does not limit the specific structure of the fastener, and any fastener that can achieve fixation between the mounting portion 9423 and the main body 941 is within the scope of protection of this embodiment.

[0298] 44 and 45, the main body 941 includes a main body and a bottom shell, the bottom shell being provided on the bottom surface of the main body and serving to support the entire body. The bottom shell has a hollow structure, and a first cavity 10 is provided in the bottom shell, and the first cavity 10 is used to accommodate the lower half of the sensor 94100. The bottom shell has an open end, and the sensor 94100 is placed in the first cavity 10 through the open end of the bottom shell.

[0299] It should be understood that the outer shape of the sensor 94100 may be a cylindrical structure or a rectangular structure, etc., and this embodiment does not limit the shape and structure of the bottom shell, fixed cover 942, and sensor 94100, and as long as the bottom shell and fixed cover 942 are respectively adapted to the outer shape of the sensor 94100, they are all within the scope of protection of this embodiment.

[0300] When the outer shape of the sensor 94100 is an approximately cylindrical structure, the first cavity 10 also has an approximately cylindrical structure, and a first axial hole and a second axial hole are provided in the first cavity 10 along its axial direction, the inner diameter of the first axial hole is slightly larger than the outer diameter of the sensor 94100, the first axial hole is adapted to the outer diameter of the sensor 94100, and the diameter of the first axial hole is larger than the diameter of the second axial hole, thereby forming a stepped hole structure, and the step 9416 of the stepped hole can seat the bottom edge of the sensor 94100, playing the role of seating and limiting the sensor 94100.

[0301] In particular, the fixed cover 942 may have a sheet-like structure, in which case the first cavity 10 is the storage cavity 943, and the fixed cover 942 may have a three-dimensional structure, with a second cavity 20 provided on the side of the fixed cover 942 facing the bottom shell, the second cavity 20 being used to store the upper half of the sensor 94100, the second cavity 20 being provided opposite the first cavity 10 and communicating with each other, and the first cavity 10 and the second cavity 20 together forming the storage cavity 943. In this way, when the bottom shell and the fixed cover 942 are fixed together, the contact area between the fixed cover 942 and the sensor 94100 is relatively large, and the fixed cover 942 serves to press-fit the sensor 94100, improving the positional stability of the sensor 94100.

[0302] In particular, the structure formed by the fixed cover 942 and the main body 941 is not a sealed structure. Specifically, as shown in FIG. 45, the fixed cover 942 is provided with a through hole 24, which may be a circular through hole. A wire harness is provided on the top of the sensor 94100, and the wire harness passes through the through hole 24 and is then electrically connected to the main board. The bottom of the sensor 94100 is disposed facing the floor surface, and a sensing signal is emitted from the bottom of the sensor 94100, which is transmitted to the carpet through the second axial hole of the first cavity 10. The sensor 94100 then transmits the received sensing signal to the main board, thereby realizing the carpet detection and identification process.

[0303] In one embodiment, as shown in FIGS. 44 and 45, the fixed portion is an extension arm 9421, the fixed fitting portion is an insertion hole 9411, and the extension arm 9421 is provided so that at least a portion thereof passes through the insertion hole 9411.

[0304] In other words, an extension arm 9421 is provided on one of the opposing sides of the fixed cover 942 and the main body 941, for example extending along the edge of the fixed cover 942 or the edge of the main body 941 to form the extension arm 9421, and an insertion hole 9411 is provided on the other of the fixed cover 942 and the main body 941, which provides an insertion space for the extension arm 9421, and at least a portion of the extension arm 9421 is provided to pass through the insertion hole 9411, thereby realizing fixation between the extension arm 9421 and the insertion hole 9411.

[0305] It should be understood that the insertion hole 9411 may be a through-hole structure, or the insertion hole 9411 may be a blind hole structure, that is, the insertion hole 9411 may be an insertion groove, and as long as the insertion between the extension arm 9421 and the insertion hole 9411 can be realized, all of them are within the protection scope of this embodiment.

[0306] In one embodiment, the extension arm 9421 is engaged with the insertion hole 9411 .

[0307] The locking action between the extension arm 9421 and the insertion hole 9411 improves the fixing effect between the extension arm 9421 and the insertion hole 9411. At this time, the first end of the fixed cover 942 is locked and fixed to the main body 941, and the second end of the fixed cover 942 is fixed to the main body 941 via the bolt 944.

[0308] When installed, the second end of the fixed cover 942 is slightly higher than the first end of the fixed cover 942, for example, by lifting the second end of the fixed cover 942 and bringing the first end of the fixed cover 942 closer to the main body 941, and the extension arm 9421 is partially inserted through the insertion hole 9411 to achieve accurate alignment between the extension arm 9421 and the insertion hole 9411 and play the role of initial pre-positioning, and then the second end of the fixed cover 942 is gradually lowered to contact the main body 941 until the extension arm 9421 is engaged in the insertion hole 9411, and finally the second end of the fixed cover 942 is connected to the main body 941 via the bolt 944 to achieve fixation between the fixed cover 942 and the main body 941.

[0309] Alternatively, the second end of the fixed cover 942 does not need to be higher than the first end of the fixed cover 942, and the first end of the fixed cover 942 can be directly moved parallel to the main body 941 until the extending arm 9421 is inserted into the insertion hole 9411. When attaching the fixed cover 942, this embodiment does not limit the relative heights of the first and second ends of the fixed cover 942, and as long as the alignment of the extending arm 9421 and the insertion hole 9411 can be achieved, any of these falls within the scope of protection of this embodiment.

[0310] In particular, it should be noted that the mutual cooperation of the fixed portion and the fixed fitting portion includes, but is not limited to, a locking connection, and may be a pivotal connection or may be fixed via other connecting members.

[0311] 44 and 45, the extension arm 9421 includes a locking portion 212 and a transition portion 94211, a first end of the transition portion 94211 is connected to the edge of the fixed cover 942, and a second end of the transition portion 94211 is connected to the locking portion 212, which is engaged with the insertion hole 9411, with the transition portion 94211 serving as an intermediate transition. If the receiving cavity 943 has a cylindrical structure, the connection position between the fixed cover 942 and the transition portion 94211 is approximately along the axial direction of the receiving cavity 943, and the depth direction of the insertion hole 9411 is approximately in the radial direction of the receiving cavity 943. In this case, the transition portion 94211 serves as an intermediate connection and also serves as a direction changer, and the extension arm 9421 essentially performs an attachment function.

[0312] In addition, the connection portion between the inside and outside of the fixed cover 942 and the transition portion 94211 may have a chamfered structure to reduce hard scratches.

[0313] In one embodiment, as shown in Figures 47 and 48, a limiting portion 9412 is provided outside the insertion hole 9411, and the limiting portion 9412 is used to restrict the extension arm 9421 so that the extension arm 9421 is provided through the insertion hole 9411.

[0314] In particular, the extension arm 9421 is provided on the side of the first end of the fixed cover 942 facing the main body 941, or the extension arm 9421 is provided on the side of the first end of the main body 941 facing the fixed cover 942. For example, the extension arm 9421 protrudes from one of the fixed cover 942 and the main body 941 to facilitate the extension arm 9421 approaching the other of the fixed cover 942 and the main body 941. A limiting portion 9412 is provided on the other of the fixed cover 942 and the main body 941, and the limiting portion 9412 is provided outside the insertion hole 9411. When the extension arm 9421 is inserted into the insertion hole 9411, the limiting portion 9412 serves to limit the extension arm 9421, ensuring accurate alignment of the extension arm 9421 with the insertion hole 9411 and improving the ease of insertion of the extension arm 9421 into the insertion hole 9411.

[0315] Specifically, the insertion hole 9411 may be directly provided in the limiting portion 9412, and the limiting portion 9412 provides an installation position for the insertion hole 9411. After the limiting portion 9412 initially positions the extension arm 9421, the extension arm 9421 is directly docked with the insertion hole 9411 provided in the limiting portion 9412, thereby improving insertion accuracy and convenience.

[0316] In one embodiment, the restrictor 9412 is a U-shaped structure, with the open end of the U-shaped structure facing the extension arm 9421 and the insertion hole 9411 located on the side of the U-shaped structure away from the open end.

[0317] The open end of the U-shaped structure faces the extension arm 9421 and provides an entrance for the extension arm 9421 to extend into the restricting portion 9412, the two side arms of the U-shaped structure restrict both sides of the extension arm 9421 to improve the facing effect, and the side of the U-shaped structure away from the open end is used to restrict the end of the extension arm 9421 to prevent the extension arm 9421 from moving a large distance beyond the outside of the restricting portion 9412. An insertion hole 9411 is provided on the side of the U-shaped structure away from the open end, for example, the open end is provided opposite the insertion hole 9411 so that the extension arm 9421 can enter from the open end and directly dock with the insertion hole 9411.

[0318] In one embodiment, as shown in FIGS. 45 and 48, the limiting portion 9412 is provided on a resting portion 9413, and the resting portion 9413 is used to rest at least a portion of the extension arm 9421 thereon.

[0319] Since the extension arm 9421 protrudes from one of the fixed cover 942 and the main body 941, a mounting portion 9413 is provided on the other of the first end of the fixed cover 942 and the main body 941, and a limiting portion 9412 is provided on the mounting portion 9413, which serves to support and mount the limiting portion 9412. At least a portion of the extension arm 9421 can be mounted on the mounting portion 9413, and the mounting portion 9413 also serves to support and mount the extension arm 9421, to support and carry the extension arm 9421, and to prevent the extension arm 9421 from coming off the insertion hole 9411 due to its own excessive weight.

[0320] In one embodiment, as shown in Figures 45 and 48, the upper and lower sides of the extension arm 9421 abut against the inner walls of the mounting portion 9413 and the insertion hole 9411, respectively, or the upper side of the extension arm 9421 abuts against the inner wall of the insertion hole 9411.

[0321] Specifically, the upper side of the locking portion 212 in the extension arm 9421 abuts against the inner wall of the insertion hole 9411, and the lower side of the locking portion 212 abuts against the top surface of the mounting portion 9413, and at this time, the mounting portion 9413 together with the insertion hole 9411 fixes the extension arm 9421.

[0322] When installing the fixed cover 942, first, the extension arm 9421 is gradually lowered near one side of the limiting portion 9412, so that the first end of the fixed cover 942 where the extension arm 9421 is provided is lower than the second end of the fixed cover 942 where the extension arm 9421 is not provided. As the extension arm 9421 passes through the insertion hole 9411, the second end of the fixed cover 942 is pressed, and when the lower side of the extension arm 9421 abuts against the mounting portion 9413, the upper side of the extension arm 9421 abuts against the inner wall of the insertion hole 9411, making it easy to operate and easy to install and remove.

[0323] It should be understood that when the thickness of the extension arm 9421 is relatively large, the upper and lower sides of the extension arm 9421 abut against the inner walls of the mounting portion 9413 and the insertion hole 9411, respectively, and when the thickness of the extension arm 9421 is relatively small, the upper side of the extension arm 9421 abuts against the inner wall of the insertion hole 9411, thereby enabling the extension arm 9421 to be fixed.

[0324] Furthermore, the first end of the fixed cover 942 is inserted into the insertion hole 9411 via the extension arm 9421 and engaged with the insertion hole 9411, and the second end of the fixed cover 942 is fixed to the main body 941 via a bolt 944. Compared with the prior art, this eliminates one screw, reduces production costs, and makes installation and removal easier.

[0325] In one embodiment, as shown in FIG. 45, a limiting protrusion 9414 is provided on one of the main body 941 and the fixed cover 942 , and a limiting groove 9422 is provided on the other, and the limiting groove 9422 is used to limit the limiting protrusion 9414 .

[0326] Specifically, a limiting protrusion 9414 is provided on the side of the main body 941 facing the fixed cover 942, and a limiting groove 9422 is provided on the fixed cover 942 corresponding to the limiting protrusion 9414. The limiting groove 9422 is used to limit the limiting protrusion 9414, and the mutual cooperation of the limiting protrusion 9414 and the limiting groove 9422 realizes the limit between the main body 941 and the fixed cover 942, and plays a role in initial pre-positioning when the fixed cover 942 is attached to the main body 941.

[0327] It should be noted that the limiting protrusion 9414 may have a columnar structure, and the cross section of the limiting protrusion 9414 may have a ring structure or a circular arc structure. It should be noted that this embodiment does not limit the shape and structure of the limiting protrusion 9414, and as long as the mutual restriction between the limiting protrusion 9414 and the limiting groove 9422 can be achieved, any of them falls within the scope of protection of this embodiment.

[0328] In one embodiment, a positioning post 9415 (shown in FIG. 44) is provided on one of the mounting portion 9423 and the main body 941, and a positioning hole 231 (shown in FIG. 47) is provided on the other, and the positioning post 9415 is provided to pass through the positioning hole 231.

[0329] Specifically, a positioning post 9415 is provided at a position corresponding to the mounting portion 9423 of the main body 941, and a positioning hole 231 is provided in the mounting portion 9423 of the fixed cover 942 corresponding to the positioning post 9415. The positioning post 9415 is provided through the positioning hole 231, thereby realizing initial positioning between the second end of the fixed cover 942 and the main body 941 and improving the fixing effect between the mounting portion 9423 and the main body 941.

[0330] The cleaning device provided in this embodiment uses a sensor mounting structure for the sensor 94100 for mounting, thereby improving the ease of mounting the sensor 94100 in the cleaning device. The sensor 94100 is used to detect the floor surface to be cleaned, and the cleaning device performs the corresponding cleaning operation based on the sensor's detection result, thereby allowing the cleaning device to smoothly perform the sweeping or mopping process. A fixing portion is provided on one side of the first end of the fixed cover 942 and the main body 941, and a fixing fitting portion is provided on the other side, which is fitted to the fixing portion. The first end of the fixed cover 942 is fixed to the main body 941 through the mutual cooperation of the fixing portion and the fixing fitting portion. The second end of the fixed cover 942 is connected to the main body 941 via a fastener, thereby fixing the second end of the fixed cover 942 to the main body 941, and both ends of the fixed cover 942 are fixed to the main body 941, resulting in a good fixing effect. The fixing cover 942 can be fixed to the main body 941 with only one fastener, eliminating one screw, while saving the assembly and maintenance time of the entire machine, reducing assembly and maintenance costs, and improving production efficiency.
