Description

Technical Field

[0001] This application relates to the field of cleaning equipment technology, and more specifically, to a cleaning module, cleaning equipment, base station, and cleaning system. Background Technology

[0002] Cleaning equipment, such as mopping robots, sweeping robots, sweeping and mopping robots, and handheld floor scrubbers, can clean the surface to be cleaned using their cleaning components. They are commonly used in home cleaning, large venue cleaning, and other similar scenarios.

[0003] After the cleaning equipment cleans the surface to be cleaned, in order to achieve the self-cleaning function of the cleaning components, the cleaned components are moistened by the liquid (which can come from the clean water tank of the cleaning equipment, etc.) in the spray bar of the cleaning equipment. The cleaning equipment is also equipped with a wastewater tank and a power unit. The air inlet of the power unit is connected to the wastewater tank, and the air outlet is connected to the spray bar. The power unit can draw air from the wastewater tank and discharge the air through the spray bar, creating a negative pressure inside the wastewater tank to recover the dirt generated during the cleaning of the cleaning components. However, both cleaning liquid and air are squeezed out through the spray bar, causing the gas and liquid inside the spray bar to mix and generate a lot of noise, affecting the user experience.

[0045] Cleaning equipment, such as mopping robots, sweeping robots, sweeping and mopping robots, and handheld floor scrubbers, can clean the surface to be cleaned using their cleaning components. They are commonly used in home cleaning, large venue cleaning, and other similar scenarios.

[0046] After cleaning the surface to be cleaned by the cleaning equipment, in order to achieve the self-cleaning function of the cleaning components, the cleaned components are moistened by the liquid in the spray bar of the cleaning equipment (which can come from the clean water box of the cleaning equipment, etc.). The cleaning equipment is also equipped with a wastewater box and a power unit, so that the cleaning equipment can mop the surface to be cleaned by moving the moistened cleaning components. At the same time, in order to achieve the self-cleaning function of the cleaning components, the cleaning equipment is also equipped with a wastewater box and a power unit. The air inlet of the power unit is connected to the wastewater box, and the air outlet is connected to the spray bar. The power unit can draw air from the wastewater box and discharge the air through the spray bar, so that the wastewater box is filled with negative pressure to recover the dirt generated during the cleaning process. However, the cleaning liquid and air are both squeezed out through the spray bar, causing the gas and liquid inside the spray bar to mix and generate a lot of noise, affecting the user experience. To solve the above technical problems, the inventors, after in-depth research, designed a cleaning module ( Figure 1 As shown), cleaning equipment ( Figure 11 As shown), base station ( Figure 12 (as shown) and cleaning system ( Figure 12 (As shown).

[0047] Please refer to the following: Figures 1 to 5The cleaning module 10 provided in the first aspect of this application is applied to a cleaning device 100. The cleaning module 10 includes a housing 11, a mopping component 12, a spraying strip 13, a recycling component 14, and an exhaust passage 15. The housing 11 is provided with an exhaust port 101. The mopping component 12 is connected to the housing 11 and is used to rotate relative to the housing 11 to mop the surface to be cleaned. The spraying strip 13 is connected to the housing 11 and is provided with a liquid inlet 131 and a liquid outlet 133. The liquid inlet 131 is used to allow liquid from an external liquid source to flow into the spraying strip 13, and the liquid outlet 133 is used to allow liquid in the spraying strip 13 to flow to the mopping component 12. The recycling component 14 includes a wastewater box 141, a recycling element 143, and a power unit 145. The recycling element 143 is connected to the housing 11 and communicates with the wastewater box 141. When the mopping element 12 mops the surface to be cleaned, the recycling element 143 is used to collect the dirt generated by the mopping element 12. The air inlet 1451 of the power unit 145 is connected to the wastewater box 141 and is used to draw negative pressure into the wastewater box 141 so that the dirt in the recycling element 143 enters the wastewater box 141. One end of the exhaust passage 15 is connected to the air outlet 1453 of the power unit 145, and the other end is connected to the air outlet 101. The exhaust passage 15 is used to allow the air drawn by the power unit 145 to flow out from the air outlet 101 to the outside of the cleaning module 10.

[0048] The cleaning device 100 is an intelligent device capable of cleaning, vacuuming, and mopping. The cleaning device 100 may include a cleaning robot or a handheld cleaning device. Cleaning robots include, but are not limited to, robotic vacuum cleaners, intelligent robots, and mobile robots; handheld cleaning devices include, but are not limited to, robotic vacuum cleaners, floor scrubbers, and floor mops. The cleaning module 10 is a device that assists the cleaning device 100 in performing mopping functions (such as wet mopping or dry mopping). When the cleaning device 100 is in normal cleaning mode, the cleaning module 10 can contact the surface to be cleaned to perform the mopping function. The surface to be cleaned may be, but is not limited to, floors, marble surfaces, carpets, or glass surfaces.

[0049] The housing 11 is a structure in the cleaning module 10 used to load and protect components such as the mop attachment 12. The housing 11 can be made of metallic and / or non-metallic materials. Metallic materials include, but are not limited to, aluminum, iron, steel, or aluminum alloys, while non-metallic materials include, but are not limited to, plastics. In some embodiments, the housing 11 is made of both metallic and non-metallic materials, which increases the structural strength of the housing 11, reduces the possibility of deformation and damage, and improves the stability and reliability of the cleaning module 10. In other embodiments, the housing 11 is made of non-metallic materials, which makes the housing 11 lighter, thus contributing to the lightweight design of the cleaning module 10.

[0050] The mopping component 12 is a component in the cleaning module 10 that rotates relative to the housing 11 to mop the surface to be cleaned. The mopping component 12 is detachably mounted on the side of the housing 11 facing the surface to be cleaned. When the cleaning device 100 is in normal cleaning mode, the mopping component 12 can rotate relative to the surface to be cleaned to achieve mopping cleaning. The mopping component 12 includes, but is not limited to, disposable electrostatic mops, disposable wet mops, or reusable fabric mops.

[0051] In some embodiments, the mopping member 12 is a tracked mop, in which case the cross-sectional shape of the mopping member 12 (the cross-section obtained by a plane perpendicular to the rotation axis of the mopping member 12) can be racetrack-shaped. In other embodiments, the mopping member 12 is a roller mop, in which case the cross-sectional shape of the mopping member 12 (the cross-section obtained by a plane perpendicular to the rotation axis of the mopping member 12) can be circular. Regardless of the type of mopping member 12, when the cleaning module 10 cleans the surface to be cleaned, the mopping member 12 is in contact with the surface to be cleaned. For example, with a tracked mop, it rotates relative to the surface to be cleaned while mopping. During the rotation of the mopping member 12, the mopping member 12 can roll away or wipe away the dirt on the surface to be cleaned, so that the surface to be cleaned remains clean. The dirt here can include liquid dirt and solid dirt. In this application, the mopping member 12 is described as a tracked mop, wherein the length direction of the housing 11 is parallel to the surface to be cleaned and perpendicular to the forward direction Y of the cleaning device 100. Figure 11 As shown, the rotation axis of the dragging component 12 is parallel to the length direction of the housing 11.

[0052] The spray bar 13 is a component in the cleaning module 10 used to provide liquid to the mop 12 for cleaning the surface to be cleaned. In some embodiments of this application, the spray bar 13 can provide liquid to the mop 12 to wet the mop 12 while it is mopping the surface to be cleaned, thus maintaining good mopping ability. In other embodiments of this application, in addition to providing liquid for cleaning the surface to be cleaned, the spray bar 13 can also provide liquid for cleaning the mop 12 after the cleaning device 100 reaches a preset position, wherein the preset position includes, but is not limited to, the base station 300 (…). Figure 12 (As shown) or areas with drainage systems, such as bathrooms. For example, the spray strip 13 can be disposed on one side of the cleaning module 10, such as on the front side of the cleaning module 10 and fixed to the front portion of the housing 11 of the cleaning module 10. The spray strip 13 has multiple liquid outlets 133, which are spaced apart along the rotation axis of the mopping member 12 and facing the mopping member 12, so that the liquid sprayed from the spray strip 13 can flow to the mopping member 12.

[0053] The external liquid source can be liquid from the clean water tank of the cleaning device 100. The clean water tank is a container used to hold and / or store liquids. It should be noted that the name "clean water tank 23" does not limit the type of liquid it contains; that is, the liquid in the clean water tank is not limited to storing only clean water, but can store liquids used for cleaning the mop parts 12, as well as cleaning and / or maintaining surfaces to be cleaned, including clean water, a mixture of cleaning agent and clean water (hereinafter referred to as cleaning liquid), and a mixture of maintenance agent and clean water (hereinafter referred to as maintenance liquid). Furthermore, "clean water" here is a relative concept; any water cleaner than what the user perceives as sewage is within the scope of protection. For example, clean water can be municipal tap water, clean river, lake, or sea water, etc. Specifically, the clean water tank can be connected to the liquid inlet 131 of the spray bar 13 so that the liquid in the clean water tank can flow to the spray bar 13. It is understood that in other embodiments, the external liquid source may also be liquid from devices such as base station 300 or sewage box 141, and this application does not impose any restrictions.

[0054] The recycling component 14 is a structure in the cleaning module 10 used to recycle dirt generated by the mop 12 when cleaning the surface to be cleaned. The recycling component 14 enables the mop 12 to have a self-cleaning function, keeping the mop 12 in a relatively clean state during the mopping process, thereby improving the cleaning effect of the cleaning equipment 100 on the surface to be cleaned.

[0055] Specifically, the wastewater container 141 is a container used for passing through, loading, and / or storing liquids. The naming of the wastewater container 141 does not limit the type of liquid it contains; that is, the liquid in the wastewater container 141 is not limited to storing only wastewater, but can store clean water, wastewater, etc. Here, "clean water" is explained as before, while "wastewater" is a relative concept; any water that is dirtier than what the user perceives as clean (or a mixture of water and waste) is within the protection scope. The wastewater container 141 can be of any shape; for example, the cross-sectional shape of the wastewater container 141 can be regular or irregular. In this paper, the cross-sectional shape of the wastewater container 141 is irregular. This irregular cross-sectional design allows it to adapt to the structural layout of the cleaning module 10, facilitating the compact arrangement of other components. In some embodiments of this application, when the cleaning device 100 is in the state of cleaning the mop 12 and the liquid level supplied to the clean water box by the external liquid source (such as the base station 300) is high, the liquid in the clean water box can overflow into the sewage box 141, and the liquid overflowing into the sewage box 141 can flow to the mop 12 through the spray bar 13.

[0056] The recycling component 143 is an element used to collect, load, and / or store dirt generated by the mopping component 12 while mopping the surface to be cleaned. The power unit 145 is an element used to regulate the air pressure (e.g., create a negative pressure) within the wastewater box 141 to allow dirt from the recycling component 143 to enter the wastewater box 141 for storage. In some embodiments, the recycling component 143 and the spray bar 13 may be located on opposite sides of the housing 11. The power unit 145 may be an air pump, etc. In some embodiments of this application, the wastewater box 141 is provided with a connecting port 1416, which is an opening for connecting the interior of the wastewater box 141 with the recycling component 143. It is understood that dirt in the recycling component 143 can enter the wastewater box 141 for storage through the connecting port 1416, and liquid (collected dirt or clean water) in the wastewater box 141 can also enter the recycling component 143 and then be discharged from the recycling component 143 to the outside of the cleaning device 100.

[0057] Specifically, please combine Figure 4 The recycling component 143 includes a dirt-containing cavity 1431 and a scraping part 1433. The dirt-containing cavity 1431 is connected to the connecting port 1416. The scraping part 1433 is used to abut against the mopping component 12 to scrape the dirt on the mopping component 12 into the dirt-containing cavity 1431. The dirt-containing cavity 1431 is used to temporarily store the dirt generated by the mopping component 12 during the mopping process. The dirt-containing cavity 1431 can extend along the rotation axis of the mopping component 12. On the one hand, it can increase the accommodating space of the dirt-containing cavity 1431. On the other hand, it can also effectively utilize the internal space of the cleaning equipment 100, reduce the cross interference between the recycling component 143 and the mopping component 12, and make the layout extending along the rotation axis of the mopping component 12 more compact, avoiding the waste of internal space of the cleaning equipment 100.

[0058] The dirt-holding cavity 1431 can be a cuboid, cylinder, or other shapes. The dirt-holding cavity 1431 can be an open cavity at the top or a closed cavity at the top. For an open cavity at the top, the top of the recycling member 143 has an opening, allowing the dirt-holding cavity 1431 to communicate directly with the outside, facilitating cleaning. For a closed cavity at the top, the top of the recycling member 143 has no opening, forming a completely closed structure at the top of the dirt-holding cavity 1431, providing better sealing and preventing dirt leakage during recycling. The scraping part 1433 abuts against the mopping member 12 to peel dirt off the mopping member 12 when cleaning the surface to be cleaned. During the operation of the cleaning equipment 100, the scraping part 1433 is in close contact with the mopping part 12. As the mopping part 12 rotates, the scraping part 1433 continuously scrapes away dirt from the clean surface of the mopping part 12, thereby maintaining the cleaning effect of the mopping part 12 and preventing dirt from re-adhering to the mopping part 12 or falling onto the surface to be cleaned, thus effectively improving the cleaning effect.

[0059] The exhaust passage 15 is a passage structure in the cleaning module 10 that connects the air outlet 1453 of the power unit 145 with the air outlet 101. In some embodiments of this application, when the mopping member 12 mops the surface to be cleaned, the recycling member 143 can collect the dirt generated by the mopping member 12. At this time, the air inlet 1451 of the power unit 145 can draw air from the wastewater box 141, and at the same time, the air outlet 1453 of the power unit 145 can discharge the drawn air to the air outlet 101 through the exhaust passage 15, so that the air is discharged to the atmosphere through the air outlet 101, thereby creating a negative pressure inside the wastewater box 141, so that the dirt in the recycling member 143 enters the wastewater box 141.

[0060] In summary, the cleaning module 10 of this embodiment uses a wastewater box 141 to collect the dirt generated by the mopping component 12 when mopping the surface to be cleaned. The mopping component 12 can mop the surface to be cleaned while simultaneously collecting the dirt generated during cleaning into the wastewater box 141 through the connection port 1416, thus realizing the self-cleaning function of the mopping component 12 in the cleaning device 100. After the cleaning device 100 reaches a preset position (e.g., base station 300), the dirt in the wastewater box 141 is discharged through the connection port 1416 to the recycling component 143, and finally discharged into the base station 300 for cleaning.

[0061] In the cleaning module 10 of this application embodiment, one end of the exhaust passage 15 is connected to the air outlet 1453 of the power device 145, and the other end is connected to the air outlet 101. The exhaust passage 15 is used to allow the air drawn by the power device 145 to flow out to the outside of the cleaning module 10 through the air outlet 101 on the housing 11. In this way, the exhaust of the power device 145 does not need to pass through the water spray bar 13, so that the water spray bar 13 is only used to supply water to the mopping part 12. There will be no problem of gas-liquid mixing inside and generating large noise (e.g., greater than 50dB), which improves the user experience.

[0062] The cleaning module 10 will be further explained below with reference to the accompanying drawings.

[0063] Please see Figure 2 , Figure 3 and Figure 6 In some embodiments, the wastewater box 141 is provided with an inner cavity 1411, which is at least used to store dirt, and the exhaust passage 15 is provided on the wastewater box 141 and is isolated from the inner cavity 1411.

[0064] In this embodiment, the exhaust passage 15 can be a passage structure provided on the sewage box 141. That is, the exhaust passage 15 is integrated on the sewage box 141 and is completely isolated from the inner cavity 1411 of the sewage box 141 for storing dirt. This makes the structure of the cleaning module 10 compact, without the need for additional external pipes, which is conducive to the miniaturization of the cleaning module 10 and saves the space occupied by the cleaning module 10. On the other hand, it can reduce the number of parts of the cleaning module 10 and facilitate the assembly of the cleaning module 10.

[0065] In some other embodiments, the exhaust passage 15 is provided on the housing 11.

[0066] In this embodiment, the exhaust passage 15 can be a passage structure provided on the housing 11, that is, the exhaust passage 15 is integrated on the housing 11. This makes the structure of the cleaning module 10 more compact, without the need for additional external pipes, which is conducive to miniaturization of the cleaning module 10 and saves the space occupied by the cleaning module 10. On the other hand, it can reduce the number of parts of the cleaning module 10 and facilitate the assembly of the cleaning module 10.

[0067] Please combine Figure 7 and Figure 8 In some other embodiments, the wastewater box 141 is provided with an inner cavity 1411, which is at least used to store dirt. A portion of the exhaust passage 15 is provided on the wastewater box 141 and is isolated from the inner cavity 1411. Another portion of the exhaust passage 15 is provided on the housing 11.

[0068] In this embodiment, part of the exhaust passage 15 is integrated into the housing 11 (hereinafter referred to as the first part), and another part is integrated into the wastewater box 141 (hereinafter referred to as the second part). Thus, when the wastewater box 141 is installed on the housing 11, the first part and the second part can connect and communicate to jointly form the exhaust passage 15. This segmented integration of the exhaust passage 15 makes the structure of the cleaning module 10 more compact, facilitating miniaturization. Furthermore, the segmented integration of the exhaust passage 15 allows it to be placed at any selectable location on the cleaning module, and also provides more options for the location of the air outlet 101 on the housing 11, enhancing layout flexibility. It is understood that a sealing structure can be provided at the joint between the first part and the second part to ensure the sealing reliability of the exhaust passage 15.

[0069] In some other embodiments, the exhaust passage 15 is a separate structure and is connected to the housing 11 and / or the wastewater box 141.

[0070] In this context, an independent structure refers to a component that can be manufactured, installed, disassembled, or replaced independently without relying on other parts of the overall structure. In this embodiment, the exhaust passage 15 is an independent structure; that is, the exhaust passage 15 is a separate structure within the cleaning module 10. For example, the exhaust passage 15 can be a pipe. This facilitates the individual replacement or maintenance of the exhaust passage 15 without requiring the complete disassembly of the wastewater box 141 or the housing 11, thus improving maintenance efficiency. Furthermore, the exhaust passage 15 can be connected to the housing 11 and / or the wastewater box 141, thereby improving installation stability.

[0071] For ease of understanding, the following embodiment will be described using the example of a sewage box 141 having an inner cavity 1411, which is at least used to store dirt, a portion of an exhaust passage 15 being located on the sewage box 141 and isolated from the inner cavity 1411, and the other portion of the exhaust passage 15 being located on the housing 11.

[0072] Please see Figure 2 , Figure 3 , Figure 5 and Figure 6 In some embodiments, the exhaust passage 15 includes a first air passage 151 and a second air passage 153. One end of the first air passage 151 is connected to the exhaust end 1453 of the power unit 145, and the other end is connected to one end of the second air passage 153. The other end of the second air passage 153 is connected to the exhaust port 101. The extension direction of the first air passage 151 and the extension direction of the second air passage 153 are different.

[0073] It should be noted that the extension direction of the first airway 151 can be the spatial orientation of its centerline, and can be straight or curved. Similarly, the extension direction of the second airway 153 can be the spatial orientation of its centerline, and can be straight or curved. Specifically, the extension directions of the first airway 151 and the second airway 153 are different; that is, the extension direction of the second airway 153 deviates somewhat from the extension direction of the first airway 151, rather than both extending in a straight line.

[0074] The extension directions of the first air passage 151 and the second air passage 153 are different. On the one hand, this helps to improve the layout flexibility of the exhaust passage 15, reduce the possibility of interference between the exhaust passage 15 and other components of the cleaning module 10, and effectively adapt to different space constraints. On the other hand, it helps to achieve noise reduction, reduce the noise generated when the gas flows in the exhaust passage 15, and improve the user experience. Specifically, the extension directions of the first air passage 151 and the second air passage 153 are different. On the one hand, the airflow changes direction when it enters the second air passage 153 from the first air passage 151, causing the sound waves generated by the airflow to be reflected and interfered with, thereby reducing noise propagation. Furthermore, when the airflow direction changes suddenly, turbulence (irregular eddies) is generated, which consumes some sound energy and reduces noise intensity. On the other hand, with the length of the housing 11 fixed, the airflow path is longer than when the extension directions of the first air passage 151 and the second air passage 153 are the same. That is, the sound wave propagation path is extended, the attenuation time of the sound wave in the exhaust passage 15 is increased, and the noise is further reduced, improving the silencing effect.

[0075] Please combine Figure 7 In some embodiments, the wastewater box 141 includes an inlet 1412, a first outlet 1413, and a second outlet 1414. The inlet 1412 is connected to the air outlet 1453 of the power unit 145. The first outlet 1413 connects the inner cavity 1411 of the wastewater box 141 and the air inlet 1451 of the power unit 145. The second outlet 1414 connects the inlet 1412 and the second air passage 153. The first air passage 151 includes the second outlet 1414, the inlet 1412, and a connecting air passage 1417. The second outlet 1414 and the inlet 1412 are respectively connected to and communicate with the opposite ends of the connecting air passage 1417. The connecting air passage 1417 is spaced apart from the inner cavity 1411 of the wastewater box 141.

[0076] Specifically, in some embodiments, when the power unit 145 is operating stably, the air inlet 1451 of the power unit 145 communicates with the inner cavity 1411 of the wastewater box 141 through the first outlet 1413 and draws gas from the inner cavity 1411. Simultaneously, the air outlet 1453 of the power unit 145 discharges the drawn gas into the connecting air passage 1417 through the inlet 1412. The gas entering the connecting air passage 1417 can flow to the second air passage 153 through the second outlet 1414. The connecting air passage 1417 is spaced from the inner cavity 1411 of the wastewater box 141, thus ensuring the stability of the negative pressure drawn by the power unit 145 onto the wastewater box 141, ensuring that the wastewater box 141 can collect the dirt recovered by the recovery component 143, and avoiding gas-liquid mixing.

[0077] In some embodiments, the flow area of ​​the connecting air passage 1417 is larger than the flow area of ​​the inlet 1412. It should be noted that the flow area refers to the effective cross-sectional area through which a fluid (such as gas or liquid) actually passes in a pipe, valve, orifice, or other flow channel. The flow area directly determines the fluid's flow capacity, affecting flow velocity, flow rate, and pressure loss. Specifically, the flow area of ​​the connecting air passage 1417 is larger than the flow area of ​​the inlet 1412; that is, the effective cross-sectional area of ​​the inlet 1412 that allows gas to pass through is smaller than the effective cross-sectional area of ​​the connecting air passage 1417 that allows gas to pass through.

[0078] Thus, the connecting air passage 1417 can form an expanded space. After the gas drawn in by the power unit 145 enters the connecting air passage 1417 through the inlet 1412, the flow area of ​​the gas increases, thereby effectively reducing exhaust noise and improving the user experience. Specifically, when the gas enters the connecting air passage 1417 through the inlet 1412, that is, when the gas enters the larger connecting air passage 1417 from the narrow inlet 1412, the airflow speed decreases, reducing friction and turbulence noise between the airflow and the inner wall of the connecting air passage 1417. Furthermore, when the gas enters the larger connecting air passage 1417 from the narrow inlet 1412, due to the sudden change in impedance, some sound waves may be reflected back to the direction of the inlet 1412, causing sound wave interference, thereby reducing noise energy.

[0079] Please see Figure 2 , Figure 3 and Figure 5 In some embodiments, the housing 11 is provided with a first mating part 111, and the sewage box 141 is provided with a second mating part 1415. The first mating part 111 and the second mating part 1415 together form a communication passage 110, and the second air passage 153 includes the communication passage 110.

[0080] Specifically, in some embodiments, when the wastewater box 141 is installed on the housing 11, the first mating part 111 and the second mating part 1415 can cooperate to form a communication passage 110, and the second air passage 153 includes the communication passage 110. That is, part of the second air passage 153 is integrated on the wastewater box 141 and the other part is integrated on the housing 11. This enables a compact layout of the cleaning module 10 and facilitates the miniaturization design of the cleaning module 10.

[0081] In some embodiments, the first mating part 111 and the housing 11 can be an integral structure, that is, the first mating part 111 and the housing 11 are an integral structure manufactured by an integral molding process. This can improve the bonding strength between the first mating part 111 and the housing 11, prevent the first mating part 111 from falling off the housing 11, and ensure the reliability of the formation of the second air passage 153. In other embodiments, the first mating part 111 and the housing 11 can be separate structures, that is, the first mating part 111 and the housing 11 are two independent structures. The first mating part 111 and the housing 11 can be connected together by a detachable connection or a non-detachable connection. Detachable connection methods include, but are not limited to, snap-fit ​​or bolt connection. Non-detachable connection methods include, but are not limited to, bonding or welding. It is understood that the arrangement of the second mating part 1415 and the sewage box 141 is basically the same as the arrangement of the first mating part 111 and the housing 11, and will not be described again here.

[0082] In some embodiments, the first mating part 111 is an annular protrusion extending from the housing 11 toward the sewage box 141, and the second mating part 1415 is the outer wall of the sewage box 141 (the outermost wall surface of the sewage box 141). The connecting passage 110 includes the inner cavity of the first mating part 111. It should be noted that in some embodiments, the cross-sectional shape of the first mating part 111 (the cross-section of the first mating part 111 obtained by a plane perpendicular to the direction from the housing 11 to the sewage box 141) can be a regular annular shape such as a circle, square, or racetrack shape, or an irregular annular shape.

[0083] In this embodiment, when the wastewater box 141 is installed on the housing 11, the first mating part 111 can abut against the second mating part 1415. That is, the end of the first mating part 111 away from the housing 11 can abut against the outer wall of the wastewater box 141, so that the inner cavity 1411 of the first mating part 111 (annular protrusion) is sealed by the second mating part 1415 to form a communication passage 110. It can be understood that the vent 101 penetrates the housing 11 and can communicate with the inner cavity of the first mating part 111.

[0084] In other embodiments, the first mating part 111 is the outer wall of the housing 11 (the wall surface of the housing 11 opposite to the sewage box 141), and the second mating part 1415 is an annular protrusion extending from the sewage box 141 toward the housing 11. The connecting passage 110 includes the inner cavity of the second mating part 1415. It should be noted that in some embodiments, the cross-sectional shape of the second mating part 1415 (the cross-section of the second mating part 1415 obtained by a plane perpendicular to the direction from the housing 11 to the sewage box 141) can be a regular annular shape such as a circle, square, or racetrack shape, or an irregular annular shape.

[0085] In this embodiment, when the sewage box 141 is installed on the housing 11, the second mating part 1415 can abut against the first mating part 111. That is, the end of the second mating part 1415 away from the sewage box 141 can abut against the outer wall of the housing 11, so that the inner cavity 1411 of the second mating part 1415 (annular protrusion) is sealed by the first mating part 111 to form a communication passage 110.

[0086] Please combine Figure 7 and Figure 8 In some embodiments, both the first mating part 111 and the second mating part 1415 are annular protrusions. The first mating part 111 extends from the housing 11 toward the sewage box 141, and the second mating part 1415 extends from the sewage box 141 toward the housing 11. The inner cavities of the first mating part 111 and the second mating part 1415 together form a communicating passage 110. The fact that both the first mating part 111 and the second mating part 1415 are annular protrusions facilitates their installation and positioning, thus improving assembly efficiency.

[0087] It should be noted that, in some embodiments, the cross-sectional shape of the first mating part 111 (the cross-section of the first mating part 111 cut by a plane perpendicular to the direction from the housing 11 to the sewage box 141) can be a regular annular shape such as a circle, square, or racetrack shape, or an irregular annular shape. Similarly, the cross-sectional shape of the second mating part 1415 (the cross-sectional shape of the second mating part 1415 cut by a plane perpendicular to the direction from the housing 11 to the sewage box 141) can be a regular annular shape such as a circle, square, or racetrack shape, or an irregular annular shape. The cross-sectional shapes of the first mating part 111 and the second mating part 1415 can be approximately the same to ensure the reliability of the mating between the first mating part 111 and the second mating part 1415.

[0088] In other embodiments, the first mating part 111 and the second mating part 1415 may both be protrusions, and the first mating part 111 extends from the housing 11 toward the sewage box 141, and the second mating part 1415 extends from the sewage box 141 toward the housing 11. When the sewage box 141 is installed on the housing 11, the first mating part 111 and the second mating part 1415 together form an annular protrusion, and the inner cavity 1411 of the annular protrusion constitutes a communicating passage 110.

[0089] In some other embodiments, the first mating part 111 may be a first groove, the first mating part 111 being recessed from the housing 11 in a direction away from the sewage box 141, the second mating part 1415 being the outer wall of the sewage box 141, and the connecting passage 110 including the first groove; or, the first mating part 111 being the outer wall of the housing 11, the second mating part 1415 being a second groove, the second mating part 1415 being recessed from the sewage box 141 in a direction away from the housing 11, and the connecting passage 110 including the second groove.

[0090] Please see Figure 2 , Figure 3 and Figure 5 In some embodiments, the first mating part 111 and the second mating part 1415 are both annular protrusions. The first mating part 111 protrudes from the housing 11 toward the sewage box 141, and the second mating part 1415 protrudes from the sewage box 141 toward the housing 11.

[0091] Specifically, in some embodiments, the first mating part 111 is disposed around the outside of the second mating part 1415, that is, the first mating part 111 wraps around the periphery of the second mating part 1415, forming a nested structure. This facilitates the installation and positioning of the first mating part 111 and the second mating part 1415, improving assembly efficiency. The first mating part 111 and the second mating part 1415 can be assembled together with a tight fit (interference fit), that is, the inner wall of the first mating part 111 and the outer wall of the second mating part 1415 abut against each other, thus improving the sealing of the communication passage 110. Alternatively, the first mating part 111 and the second mating part 1415 can be assembled together with a loose fit (clearance fit), that is, the inner wall of the first mating part 111 and the outer wall of the second mating part 1415 have a certain gap, thus facilitating quick assembly and disassembly.

[0092] In other embodiments, the second mating part 1415 is disposed around the outside of the first mating part 111, that is, the second mating part 1415 wraps around the periphery of the first mating part 111, forming a nested structure. This facilitates the installation and positioning of the first mating part 111 and the second mating part 1415, improving assembly efficiency. The first mating part 111 and the second mating part 1415 can be assembled together with an interference fit, that is, the inner wall of the second mating part 1415 abuts against the outer wall of the first mating part 111, thus improving the sealing of the communication passage 110. Alternatively, the first mating part 111 and the second mating part 1415 can be assembled together with a loose fit, that is, the inner wall of the second mating part 1415 and the outer wall of the first mating part 111 have a certain gap, thus facilitating quick assembly and disassembly.

[0093] In some other embodiments, the end of the first mating part 111 away from the housing 11 and the end of the second mating part 1415 away from the wastewater box 141 abut against each other. Thus, compared to a nested structure formed by the first mating part 111 and the second mating part 1415, the flow area of ​​the connecting passage 110 (second air passage 153) formed by the first mating part 111 and the second mating part 1415 is larger, thereby improving the gas emission efficiency.

[0094] In some embodiments, the cleaning module 10 further includes a seal 16 for preventing gas in the second air passage 153 from flowing out of the assembly gap formed by the first mating part 111 and the second mating part 1415.

[0095] Specifically, the seal 16 is used to seal the assembly gap formed by the first mating part 111 and the second mating part 1415 to enhance the sealing effect of the second air passage 153. The seal 16 can be made of materials such as rubber, silicone, plastic, or synthetic fibers. Among them, rubber materials include, but are not limited to, natural rubber, nitrile rubber, fluororubber, polyurethane rubber, EPDM rubber, or silicone rubber. The number of seals 16 can be one or more, and this application does not limit it.

[0096] In some embodiments, the sealing member 16 is disposed between the first mating portion 111 and the second mating portion 1415. Thus, the sealing member 16 can seal the gap between the first mating portion 111 and the second mating portion 1415, preventing gas in the second air passage 153 from flowing out through the gap between the first mating portion 111 and the second mating portion 1415, thereby improving the airtightness of the second air passage 153. For example, when both the first mating portion 111 and the second mating portion 1415 are annular protrusions, the sealing member 16 can be disposed between the sidewalls of the two annular protrusions. The sealing member 16 can be separately molded and disposed between the first mating portion 111 and the second mating portion 1415; or, the sealing member 16 can be separately molded and fitted into the first mating portion 111 or the second mating portion 1415; or, the sealing member 16 can be fitted and molded into the first mating portion 111 or the second mating portion 1415 in the form of overmolding or similar methods.

[0097] In other embodiments, the seal 16 is disposed between the first mating part 111 and the sewage box 141. For example, the first mating part 111 is an annular protrusion, and the second mating part 1415 is the outer wall of the sewage box 141. In this case, the seal 16 is disposed between the first mating part 111 and the sewage box 141, thereby sealing the gap between the first mating part 111 and the outer wall of the sewage box 141, that is, sealing the assembly gap formed by the first mating part 111 and the second mating part 1415, and ensuring the airtightness of the second air passage 153. For example, both the first mating part 111 and the second mating part 1415 are annular protrusions. When the first mating part 111 and the second mating part 1415 are mated, the end of the first mating part 111 away from the housing 11 can abut against the sewage box 141. At this time, the sealing member 16 is provided between the first mating part 111 and the sewage box 141, thereby sealing the gap between the first mating part 111 and the sewage box 141, that is, sealing the assembly gap formed by the first mating part 111 and the second mating part 1415, and ensuring the airtightness of the second air passage 153.

[0098] In some other embodiments, the seal 16 is disposed between the second mating portion 1415 and the housing 11. For example, the second mating portion 1415 is an annular protrusion, and the first mating portion 111 is the outer wall of the housing 11. In this case, the seal 16 is disposed between the second mating portion 1415 and the housing 11, thereby sealing the gap between the second mating portion 1415 and the outer wall of the housing 11, that is, sealing the assembly gap formed by the first mating portion 111 and the second mating portion 1415, and ensuring the airtightness of the second air passage 153. For example, both the first mating part 111 and the second mating part 1415 are annular protrusions. When the first mating part 111 and the second mating part 1415 are mated, the end of the second mating part 1415 away from the sewage box 141 can abut against the housing 11. At this time, the sealing member 16 is provided between the second mating part 1415 and the housing 11, thereby sealing the gap between the second mating part 1415 and the housing 11, that is, sealing the assembly gap formed by the first mating part 111 and the second mating part 1415, and ensuring the airtightness of the second air passage 153.

[0099] In one embodiment of this application, both the first mating part 111 and the second mating part 1415 are annular protrusions, and the second mating part 1415 is arranged around the outside of the first mating part 111. The sealing member 16 is annular and is sleeved on the outside of the first mating part 111, located between the second mating part 1415 and the housing 11. Thus, the sealing member 16 can seal the gap between the second mating part 1415 and the outer wall of the housing 11, that is, seal the assembly gap formed by the first mating part 111 and the second mating part 1415, ensuring the airtightness of the second air passage 153. Specifically, the housing 11 is also provided with a blocking member 17, which is disposed on the outside of the first mating part 111 and spaced apart from the first mating part 111. An installation space is formed between the blocking member 17 and the first mating part 111, and the sealing member 16 can be installed in the installation space. Thus, the blocking member 17, on the one hand, prevents the seal 16 from moving relative to the housing 11, ensuring that the seal 16 can stably seal the assembly gap formed by the first mating part 111 and the second mating part 1415; on the other hand, it provides positioning for the installation of the seal 16, improving the assembly efficiency of the seal 16. It can be understood that the blocking member 17 can be an annular structure (in this case, the blocking member 17 is arranged around the outside of the first mating part 111) or a non-annular structure. For example, the blocking member 17 can be a multi-segment structure (in this case, the blocking member 17 is arranged on the outside of the first mating part 111 and spaced apart along the circumferential direction of the first mating part 111).

[0100] Please see Figure 2 , Figure 3 , Figure 5 , Figure 7 and Figure 8 In some embodiments, the second air passage 153 is elongated. That is, the length of the second air passage 153 (the dimension of the second air passage 153 in its extending direction) is much greater than the width or height of the second air passage 153, and the second air passage 153 can be generally formed as a flat rectangular tube or a slit-like channel. The cross-sectional shape of the second air passage 153 (the cross-section of the second air passage 153 obtained by a plane perpendicular to the extending direction of the second air passage 153) can be rectangular, elliptical, circular, or irregular, etc. The second air passage 153 can be straight, spiral, or bent, etc., so that the second air passage 153 can better adapt to the spatial layout of the cleaning module 10.

[0101] The second air passage 153 is elongated, which creates a better noise reduction effect and improves the user experience. Specifically, on the one hand, the elongated airflow channel forces the airflow to slow down, thereby reducing turbulence noise; on the other hand, the inner wall of the elongated channel reflects sound waves multiple times, and some sound energy can be converted into heat energy, thereby attenuating mid-to-high frequency noise; furthermore, the elongated channel makes the airflow path longer, that is, it prolongs the sound wave propagation path and increases the attenuation time of sound waves in the second air passage 153, further reducing noise and improving the noise reduction effect.

[0102] In some embodiments, the air outlet 101 and the first air passage 151 are respectively connected to and communicate with the opposite ends of the second air passage 153. For example, the second air passage 153 can be straight, in which case the opposite ends of the second air passage 153 can be the two ends furthest apart on the second air passage 153 in its extension direction. The connection and communication between the air outlet 101 and the first air passage 151 and the opposite ends of the second air passage 153 extends the airflow path, which is beneficial for improving the noise reduction effect. As another example, the second air passage 153 can be spiral-shaped, that is, the second air passage 153 can be a channel structure formed by spiraling around a central axis. In this case, the opposite ends of the second air passage 153 can be the center of the second air passage 153 (such as the starting end of the spiral) and the spiral end of the second air passage 153. Again, the connection and communication between the air outlet 101 and the first air passage 151 and the opposite ends of the second air passage 153 extends the airflow path, which is beneficial for improving the noise reduction effect.

[0103] It is understandable that when the power unit 145 draws gas from the inner cavity 1411 of the sewage tank, some liquid may be carried out, causing water to drip from the air outlet 101. If the liquid from the air outlet 101 drips directly onto the surface to be cleaned, it will affect the cleaning effect. Therefore, please consider... Figure 5 In some embodiments of this application, the air outlet 101 is oriented opposite to the mopping member 12. Thus, when gas flows out of the air outlet 101, it flows towards the mopping member 12, causing the liquid carried out with the gas to be sprayed onto and absorbed by the mopping member 12, preventing liquid from dripping onto the surface to be cleaned, thereby improving the cleaning effect. It should be noted that in some embodiments, the air outlet 101 is oriented opposite to the mopping member 12; that is, the central axis of the air outlet 101 intersects with the mopping member 12.

[0104] In some embodiments, when the cleaning device 100 cleans the surface to be cleaned, the height direction Z of the cleaning module 10 is perpendicular to the surface to be cleaned. In the projection within the plane perpendicular to the height direction Z of the cleaning module 10, the projection of the air outlet 101 lies within the projection of the mopping member 12. That is, the air outlet 101 is located above the mopping member 12. This ensures that dripping or leaking water from the air outlet 101 falls onto the mopping member 12, preventing contamination of the surface to be cleaned and improving the cleaning device 100's efficiency. Figure 11 The cleaning effect is shown in the figure.

[0105] Please see Figures 9 to 11 In some embodiments, when the cleaning device 100 cleans the surface to be cleaned, in the forward direction Y of the cleaning device 100, the housing 11 includes a first end 102 and a second end 103 opposite to each other, and in the rotation direction of the mopping member 12, the first end 102 is located upstream of the second end 103. As the mopping member 12 rotates, the portion of the mopping member 12 that contacts the surface to be cleaned passes through the first end 102 and then the second end 103 after contacting the surface to be cleaned. The housing 11 has an inner surface 104 facing the mopping member 12, and the inner surface 104 is provided with a stop portion 113, which is close to the first end 102. The stop portion 113 abuts against the mopping member 12 to stop any entanglement on the mopping member 12.

[0106] It should be noted that the first end 102 of the housing 11 can be the preferred contact end for the dirty area formed when the mop 12 cleans the surface to be cleaned. The stop portion 113 is a protruding structure on the inner surface 104 of the housing 11 facing the mop 12. The stop portion 113 can be used to stop tangled objects (such as hair, fibers, tufts, carpets, felt, etc.) on the mop 12. When the mop 12 rotates to mop the surface to be cleaned, the stop portion 113 can stop the tangled objects on the mop 12, preventing them from being rolled into the mop 12 and affecting the normal rotation of the mop 12, thereby improving the stability and reliability of the cleaning module 10. For example, when the mop 12 carrying tangled objects comes into contact with the stop portion 113, the stop portion 113 can "scoop" them up from the surface of the mop 12, thereby ensuring the stable rotation of the mop 12.

[0107] Specifically, when the cleaning device 100 cleans the surface to be cleaned, part of the structure of the mopping member 12 contacts the surface to be cleaned and mops the surface to be cleaned to form a dirty area. At this time, the dirty area first passes through the first end 102 of the housing 11 under the rotation of the mopping member 12 and enters the range of action of the stop part 113 so that the entanglement on the mopping member 12 is stopped by the stop part 113. Then the dirty area can pass through the second end 103 of the housing 11 under the rotation of the mopping member 12, and then break away from the contact with the housing 11 and re-contact the surface to be cleaned.

[0108] It is understood that the recycling component 143 can be located at the second end 103 of the housing 11. In this way, when the dirty area passes through the second end 103 of the housing 11, that is, when the dirty area enters the effective range of the recycling component 143, the recycling component 143 can collect the dirt generated by the mopping component 12 when it mops the surface to be cleaned. This allows the mopping component 12 to be in a relatively clean state when it is separated from the housing 11 and re-contacts the surface to be cleaned, thereby improving the cleaning effect.

[0109] In some embodiments, the stop portion 113 and the housing 11 can be an integral structure, that is, the stop portion 113 and the housing 11 are a single structure manufactured using an integral molding process. This improves the bonding strength between the stop portion 113 and the housing 11, prevents the stop portion 113 from detaching from the housing 11, and ensures the reliability of the stop portion 113's operation. In other embodiments, the stop portion 113 and the housing 11 can be separate structures, that is, the stop portion 113 and the housing 11 are two independent structures. The stop portion 113 and the housing 11 can be joined together using a detachable connection method or a non-detachable connection method. Detachable connection methods include, but are not limited to, snap-fit ​​or bolted connections. Non-detachable connection methods include, but are not limited to, bonding or welding.

[0110] In some embodiments, the first end 102 of the housing 11 includes a bottom surface 105, which is opposite to the surface to be cleaned, and a stop portion 113 is adjacent to the bottom surface 105.

[0111] The stop portion 113 is adjacent to the bottom surface 105, that is, the stop portion 113 and the bottom surface 105 are in direct contact; or, the stop portion 113 is connected to the bottom surface 105 through a transition structure. This can help the stop portion 113 and the bottom surface 105 to form a physical barrier together, so that the entangled material on the mopping component 12 can be effectively blocked before it is rolled into the housing 11, thereby improving the stability and reliability of the cleaning module 10.

[0112] Please combine Figure 10 In some embodiments, the stop portion 113 includes adjacent abutting surfaces 1131 and stop surfaces 1133. The abutting surfaces 1131 abut against the mopping member 12, and the stop surfaces 1133 face the surface to be cleaned. The stop surfaces 1133 are used to stop the entanglement on the mopping member 12.

[0113] The contact surface 1131 is the surface on the stop portion 113 that can dynamically contact the mopping member 12. The stop surface 1133 is the surface on the stop portion 113 that faces the surface to be cleaned, and the stop surface 1133 can act as an intercepting surface for tangled objects. It can be understood that the stop portion 113 can be interference-fitted with the mopping member 12 while ensuring stable rotation of the mopping member 12. This ensures that the stop surface 1133 can more effectively stop tangled objects on the mopping member 12, preventing tangled objects from being rolled into the space between the mopping member 12 and the housing 11 through the gap between the contact surface 1131 and the mopping member 12, thereby improving the stability and reliability of the cleaning module 10.

[0114] In some embodiments, the stop surface 1133 and the bottom surface 105 of the housing 11 are at the same horizontal level. In this way, the entangled material on the drag member 12 can be effectively blocked before it is rolled into the housing 11. In addition, when the stop surface 1133 is subjected to force, the external force can be transmitted to the housing 11 and evenly distributed, preventing the stop surface 1133 from bearing pressure alone and reducing the possibility of deformation and damage to the stop part 113.

[0115] In other embodiments, the stop surface 1133 is closer to the surface to be cleaned relative to the bottom surface 105 of the housing 11. Thus, compared to when the stop surface 1133 and the bottom surface 105 of the housing 11 are at the same horizontal level, the intercepting surface contacted by the tangled material on the mop 12 is smaller (including only the stop surface 1133) when stopping the tangled material, making it easier for the stop portion 113 to scrape the tangled material off the surface of the mop 12. Furthermore, the stop surface 1133 protrudes from the bottom surface 105 of the housing 11, reducing the likelihood of the stopped tangled material accumulating between the housing 11 and the stop portion 113, allowing for quick removal of the scraped-off tangled material, and preventing excessive stopped tangled material from affecting the normal rotation of the mop 12.

[0116] In some embodiments, the stop portion 113 includes a plurality of comb teeth 1135 arranged at intervals along the length direction of the housing 11, the comb teeth 1135 being used to abut against the dragging member 12. Thus, compared to the stop portion 113 being a continuous structure along the length of the housing 11, the stop portion 113 includes multiple comb teeth 1135. On the one hand, this can reduce the friction between the stop portion 113 and the mopping member 12, making the rotation of the mopping member 12 smoother and less strenuous, which helps to reduce the power consumption required to drive the rotation of the mopping member 12 and extend the standby time of the cleaning device 100. On the other hand, while the stop portion 113 can stop the tangled objects, it can also allow smaller dirt to enter between the mopping member 12 and the housing 11 through the gap between two adjacent comb teeth 1135 when the mopping member 12 rolls up the dirt, and finally be collected by the recycling member 143, instead of the dirt rolled up by the mopping member 12 being completely stopped by the stop portion 113. This can improve the mopping cleaning effect of the mopping member 12 on the surface to be cleaned.

[0117] In some embodiments, the comb teeth 1135 include an abutment surface 1131 and a stop surface 1133, with the abutment surface 1131 perpendicular to the surface to be cleaned. It should be noted that in some embodiments, the abutment surface 1131 can be straight or curved. When the abutment surface 1131 is curved, the tangent direction at the connection point between the abutment surface 1131 and the stop surface 1133 is perpendicular to the surface to be cleaned. It is understood that the explanations of the abutment surface 1131 and the stop surface 1133 in the foregoing embodiments also apply to the abutment surface 1131 and the stop surface 1133 in this embodiment, and will not be repeated here.

[0118] In some embodiments, the contact surface 1131 gradually moves away from the surface to be cleaned from the mop member 12. This reduces the contact area between the contact surface 1131 and the mop member 12, thereby reducing the friction between them, ensuring smoother and less strenuous rotation of the mop member 12, reducing the power consumption required to drive the mop member 12 to rotate, and extending the standby time of the cleaning device 100.

[0119] Please see Figures 2 to 5 and combined Figure 11The cleaning device 100 provided in this application embodiment includes a body 30 and a cleaning module 10 of any of the above embodiments, wherein the cleaning module 10 is disposed on the body 30. It should be noted that the cleaning device 100 and cleaning module 10 in this embodiment are the same as those in the above embodiments. Therefore, the explanations and descriptions of the cleaning device 100 and cleaning module 10 in the previous embodiments also apply to the cleaning device 100 and cleaning module 10 in this embodiment, and similarly, the explanations and descriptions of the cleaning device 100 and cleaning module 10 in this embodiment also apply to the cleaning device 100 and cleaning module 10 in the previous embodiments.

[0120] The housing 30 is a device for mounting and protecting the cleaning module 10 and other structures. The housing 30 can be made of metallic and / or non-metallic materials. Metallic materials include, but are not limited to, aluminum, iron, steel, or aluminum alloys, while non-metallic materials include, but are not limited to, plastics. In some embodiments, the housing 30 can be made of both metallic and non-metallic materials, thereby increasing its structural strength, preventing collision damage during operation of the cleaning equipment 100, and improving the stability and reliability of the cleaning equipment 100. In other embodiments, the housing 30 can be made of non-metallic materials, thereby reducing its weight and making the cleaning equipment 100 more portable.

[0121] In the cleaning device 100 of this application embodiment, one end of the exhaust passage 15 is connected to the air outlet 1453 of the power unit 145, and the other end is connected to the air outlet 101. The exhaust passage 15 is used to allow the air drawn by the power unit 145 to flow out to the outside of the cleaning module 10 through the air outlet 101 on the housing 11. In this way, the exhaust of the power unit 145 does not need to pass through the water spray bar 13, so that the water spray bar 13 is only used to supply water to the mopping part 12. There will be no problem of gas-liquid mixing inside and generating a lot of noise, thus improving the user experience.

[0122] In some embodiments, the body 30 is provided with a suction inlet and a waste chamber, the suction inlet connecting the waste chamber to the outside of the cleaning device 100; the cleaning device 100 also includes a roller brush 50 and / or a side brush 70. The roller brush 50 is mounted at the suction inlet of the body 30 and rotates relative to the body 30 to carry debris from the surface to be cleaned into the waste chamber. The side brush 70 is mounted on the body 30, and in the forward direction Y of the cleaning device 100, the center of the side brush 70 is located in front of the suction inlet. The side brush 70 rotates relative to the body 30 to sweep debris from the surface to be cleaned toward the suction inlet and / or the roller brush 50. For ease of understanding, the following embodiments use the cleaning device 100 including the roller brush 50 and the side brush 70 as an example for explanation.

[0123] The suction inlet is an opening on the body 30 for sweeping debris from the surface to be cleaned into the waste chamber. When the cleaning device 100 is cleaning the surface, the suction inlet is opposite to the surface. The waste chamber is a cavity structure for storing debris. When the cleaning device 100 is cleaning the surface, the side brush 70 sweeps debris (such as dust) from the surface towards the roller brush 50 and / or the suction inlet, and the roller brush 50 then sweeps the debris from the suction inlet into the waste chamber. It can be understood that along the forward direction Y of the cleaning device 100, the side brush 70 is located at the front of the body 30, the suction inlet can be located in the middle of the body 30 (between the front and rear sides of the body 30), and the cleaning module 10 can be located at the rear of the body 30. Thus, the cleaning device 100 can perform both sweeping and mopping functions, thereby improving the cleaning effect of the cleaning device 100.

[0124] It should be noted that the orientations described in the embodiments of this application are defined when the cleaning device 100 is cleaning the surface to be cleaned. "Front side" and "rear side" are relative to the forward direction Y of the cleaning device 100. When the cleaning device 100 moves forward along the forward direction Y, the foremost point of the body 30 closest to the forward direction Y is the front side of the body 30, and the rearmost point of the body 30 closest to the forward direction Y is the rear side of the body 30. The foremost point of the suction inlet closest to the forward direction Y is the front side of the suction inlet.

[0125] Please see Figures 2 to 5 and combined Figure 11 and Figure 12 The base station 300 provided in the third aspect of this application is used to maintain the cleaning device 100 of any of the above embodiments. It should be noted that the cleaning device 100 in this embodiment is the same as the cleaning device 100 in the above embodiments. Therefore, the explanation of the cleaning device 100 in the above embodiments also applies to the cleaning device 100 in this embodiment, and similarly, the explanation of the cleaning device 100 in this embodiment also applies to the cleaning device 100 in the above embodiments.

[0126] The cleaning base station 300 is a device that can be used in conjunction with the cleaning equipment 100. For example, when the cleaning equipment 100 needs to perform a cleaning task, it leaves the cleaning base station 300 and can clean the surface to be cleaned. When the cleaning equipment 100 has completed its cleaning task or no longer needs to perform a cleaning task, it can dock at the docking position of the cleaning base station 300. In this case, the cleaning base station 300 can perform maintenance on the cleaning equipment 100, including but not limited to charging or self-cleaning maintenance (e.g., dust collection, cleaning the mop parts 12, adding clean water, pumping out wastewater, etc.).

[0127] In the base station 300 of this application embodiment, one end of the exhaust passage 15 is connected to the air outlet 1453 of the power device 145, and the other end is connected to the air outlet 101. The exhaust passage 15 is used to allow the air drawn by the power device 145 to flow out to the outside of the cleaning module 10 through the air outlet 101 on the housing 11. In this way, the exhaust of the power device 145 does not need to pass through the water spray bar 13, so that the water spray bar 13 is only used to supply water to the mopping component 12. There will be no problem of gas-liquid mixing inside and generating a lot of noise, thus improving the user experience.

[0128] Please see Figures 2 to 5 and combined Figure 11 and Figure 12 The cleaning system 1000 provided in the fourth aspect of this application includes the cleaning device 100 of any of the above embodiments; and / or, the base station 300 of the above embodiments, the base station 300 being used to maintain the returned cleaning device 100. It should be noted that the cleaning device 100 and base station 300 in this embodiment are the same as those in the above embodiments. Therefore, the explanations and descriptions of the cleaning device 100 and base station 300 in the aforementioned embodiments also apply to the cleaning device 100 and base station 300 in this embodiment. Similarly, the explanations and descriptions of the cleaning device 100 and base station 300 in this embodiment also apply to the cleaning device 100 and base station 300 in the aforementioned embodiments.

[0129] In the cleaning system 1000 of this application embodiment, one end of the exhaust passage 15 is connected to the air outlet 1453 of the power unit 145, and the other end is connected to the air outlet 101. The exhaust passage 15 is used to allow the air drawn by the power unit 145 to flow out to the outside of the cleaning module 10 through the air outlet 101 on the housing 11. In this way, the exhaust of the power unit 145 does not need to pass through the water spray bar 13, so that the water spray bar 13 is only used to supply water to the mopping part 12. There will be no problem of gas-liquid mixing inside and generating a lot of noise, thus improving the user experience.

[0130] The technical features of the embodiments described above can be combined arbitrarily. For the sake of brevity, not all possible combinations of the technical features in the above embodiments are described. However, as long as the combination of these technical features does not contradict each other, it should be considered within the scope of this specification. Furthermore, other implementation methods can be derived from the above embodiments, allowing for structural and logical substitutions and changes without departing from the scope of this disclosure.

[0131] The embodiments described above are merely illustrative of several implementation methods of this application, and while the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the patent. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this application, and these all fall within the protection scope of this application. Therefore, the protection scope of this patent application should be determined by the appended claims.
