Description

Technical Field

[0001] This disclosure relates to the field of clean technology, and more specifically, to a cleaning device, a base station, and a cleaning system. Background Technology

[0002] After cleaning a surface, the mopping parts of a cleaning device will retain wastewater. Continuing to clean the surface with this wastewater will result in poor cleaning effectiveness. Therefore, cleaning equipment typically includes a wastewater tank to collect and recycle the wastewater from the mopping parts, thereby improving cleaning efficiency. A drain pipe connected to the wastewater tank is usually provided for discharging the wastewater. Current drain pipes typically have valves that open when the wastewater needs to be discharged and close when it doesn't. However, wastewater often contains solid debris, such as hair, which can easily clog the drain pipe when passing through the valve. Utility Model Content

[0003] This disclosure provides a cleaning device, a base station, and a cleaning system for cleaning equipment.

[0004] In a first aspect, embodiments of this disclosure provide a cleaning device. The cleaning device includes a wastewater box, a collection component, a drain pipe, and a force application unit. The wastewater box is used to store wastewater. The collection component is used for temporary storage of wastewater. The collection component has a sludge-containing cavity and a wastewater outlet, the wastewater outlet connecting the sludge-containing cavity and the wastewater box. The drain pipe connects the sludge-containing cavity to the outside. The drain pipe is a flexible hose; the drain pipe includes a drain outlet located at the end of the drain pipe away from the sludge-containing cavity. The force application unit is connected to the drain pipe and is used to apply a force to the drain pipe to change the bending state of the drain pipe, thereby switching the drain pipe between a non-drained state and a drained state. Specifically, when the drain pipe is not discharging sewage, it is in a first bent state and the position of the drain outlet is higher than the position of the sludge chamber, so as to prevent sewage in the sludge chamber from being discharged to the outside through the drain pipe; when the drain pipe is discharging sewage, the position of the drain outlet is not higher than the position of the sludge chamber, so as to allow sewage in the sewage box to be discharged to the outside in sequence through the sewage outlet, the sludge chamber, and the drain pipe.

[0005] In some embodiments, when the drain pipe is in the draining state, the drain pipe is in a straight line and the drain outlet is at the same height as the sewage chamber.

[0006] In some embodiments, when the drain pipe is in a draining state, the drain pipe is in a second bent state and the position height of the drain outlet is lower than the position height of the sludge-containing cavity.

[0007] In some embodiments, the drain pipe is in a straight line under natural conditions.

[0008] In some embodiments, when the drain pipe is not draining, the angle between the central axis of the drain outlet extending away from the sludge chamber and the height direction of the cleaning device from bottom to top is zero or an acute angle; when the drain pipe is draining, the angle between the central axis of the drain outlet extending away from the sludge chamber and the height direction of the cleaning device from bottom to top is greater than or equal to 90°.

[0009] In some embodiments, the drain pipe is in a conductive state both when it is in a non-draining state and when it is in a draining state.

[0010] In some embodiments, the cleaning device includes a cleaning component. The collection component includes a scraping portion that abuts against the cleaning component. At least a portion of the dirt-receiving cavity is lower than the scraping portion. During rotation of the cleaning component, the scraping portion peels dirt off the cleaning component.

[0011] In some embodiments, the recycling component includes a filter. The filter is positioned higher than the scraper in the height direction of the cleaning device. The filter has filter holes that connect the outside to the sludge-holding chamber, allowing wastewater from the sludge to enter the chamber while blocking solid waste from entering.

[0012] In some embodiments, the force-applying unit includes a transmission component, a reset component, and a force-receiving component. A first end of the transmission component is connected to the drain pipe. The reset component includes a fixed end and a movable end; the fixed end is connected to the housing of the cleaning equipment, and the movable end of the reset component is connected to a second end of the transmission component. The reset component has a first state and a second state. When the reset component is in the first state, it drives the transmission component to put the drain pipe in a non-drainage state; when the reset component is in the second state, it drives the transmission component to put the drain pipe in a drainage state. The force-receiving component is connected to the movable end of the reset component; an external force is applied to the force-receiving component to allow the reset component to switch between the first state and the second state.

[0013] In some embodiments, when the drain pipe is in a non-draining state, the force-bearing member is not subjected to external force. When the drain pipe is in a draining state, the force-bearing member is continuously subjected to external force.

[0014] In some embodiments, the reset member is an elastic member. In the first state, the elastic member is in a natural state or in a first compressed state. In the second state, the elastic member is in a second compressed state. The degree of compression in the first compressed state is less than the degree of compression in the second compressed state.

[0015] In some embodiments, the reset member is an elastic member. In the first state, the elastic member is in a natural state or in a first stretched state. In the second state, the elastic member is in a second stretched state. The degree of stretching in the first stretched state is less than the degree of stretching in the second stretched state.

[0016] In some embodiments, when the drain pipe switches between a non-drained state and a drained state, the force-bearing member switches between a first position and a second position along the extension direction of the transmission member. The travel distance between the first position and the second position is greater than or equal to a first distance. The first distance is the difference between the height of the connection between the transmission member and the drain pipe in the non-drained state and the height of the axis of the drain pipe in the straight state.

[0017] In some embodiments, at least the recycling component, the drain pipe, and the force application unit are movable as a whole along the width direction of the cleaning equipment, such that at least a portion of the force-receiving component of the force application unit protrudes relative to the outer contour of the cleaning equipment body.

[0018] In some embodiments, the force-applying unit further includes a fixing seat disposed on the outer wall of the sewage pipe; the fixing seat is provided with a rotating shaft, and the transmission component is connected to the rotating shaft.

[0019] In some embodiments, the cleaning device further includes: a first protective member installed on the drain pipe; in the non-drained state, the first protective member at least covers the side of the drain pipe facing the cleaning device that is closer to the drain pipe.

[0020] In some embodiments, the cleaning device further includes a power unit. The power unit is connected to the wastewater box and is used to provide negative pressure to the wastewater box to draw wastewater from the sludge-containing cavity into the wastewater box through the wastewater inlet, and to provide positive pressure to the wastewater box so that the wastewater in the wastewater box is discharged to the outside through the wastewater inlet, the sludge-containing cavity, and the drain pipe.

[0021] Secondly, embodiments of this disclosure provide a base station. The base station is used for maintaining cleaning equipment. The cleaning equipment includes a wastewater box, a collection component, a drain pipe, and a force application unit. The collection component has a sludge-containing cavity and a wastewater outlet, the wastewater outlet connecting the sludge-containing cavity and the wastewater box. The drain pipe connects the sludge-containing cavity to the outside. The drain pipe is a flexible hose. The drain pipe includes a drain outlet located at the end of the drain pipe away from the sludge-containing cavity. The force application unit is connected to the drain pipe and is used to apply a force to the drain pipe to change the bending state of the drain pipe, thereby switching the drain pipe between a non-drained state and a drained state. In the drained state, wastewater in the wastewater box is discharged to the outside sequentially through the wastewater outlet, the sludge-containing cavity, and the drain pipe. In the non-draining state, the drain pipe is in a first bent state, and the position of the drain outlet is higher than the position of the sludge-containing cavity, thus preventing sewage in the sludge-containing cavity from being discharged to the outside through the drain pipe. In the drain pipe's draining state, the position of the drain outlet is not higher than the position of the sludge-containing cavity, allowing sewage in the sewage box to be discharged to the outside sequentially through the drain outlet, the sludge-containing cavity, and the drain pipe. The base station includes a second force-applying component. The second force-applying component provides external force to the force-applying unit and can change the force applied to the drain pipe through the force-applying unit, so that the drain pipe can switch between a non-draining state and a draining state.

[0022] In some embodiments, when the cleaning equipment returns to the base station, at least the recycling component, the drain pipe, and the force application unit can move as a whole along the width direction of the cleaning equipment so that at least a portion of the force application unit protrudes relative to the outer contour of the cleaning equipment body, the second force application component abuts against the force application unit to apply the external force to the force application unit.

[0023] Thirdly, embodiments of this disclosure provide a cleaning system, which includes cleaning equipment and a base station. The cleaning equipment includes a wastewater box, a collection component, a drain pipe, and a force application unit. The collection component has a wastewater holding chamber and a wastewater outlet, the wastewater outlet connecting the wastewater holding chamber and the wastewater box. The drain pipe connects the wastewater holding chamber to the outside. The drain pipe is a flexible hose; the drain pipe includes a drain outlet located at the end of the drain pipe away from the wastewater holding chamber. The force application unit is connected to the drain pipe and is used to apply a force to the drain pipe to change the bending state of the drain pipe, thereby switching the drain pipe between a non-drained state and a drained state. In the non-draining state, the drain pipe is in a first bent state, and the position of the drain outlet is higher than the position of the sludge-containing cavity, thus preventing sewage in the sludge-containing cavity from being discharged to the outside through the drain pipe. In the drain pipe's draining state, the position of the drain outlet is not higher than the position of the sludge-containing cavity, allowing sewage in the sewage box to be discharged to the outside sequentially through the drain outlet, the sludge-containing cavity, and the drain pipe. The base station includes a second force-applying component. The second force-applying component provides external force to the force-applying unit and can change the force applied to the drain pipe through the force-applying unit, so that the drain pipe can switch between a non-draining state and a draining state.

[0024] In the cleaning equipment, base station, and cleaning system of this disclosure, the cleaning equipment adjusts the force applied to the drain pipe by setting a force application unit to change the bending state of the drain pipe, enabling the recyclable component to switch between a non-drained state and a drained state, thereby achieving efficient draining of the recyclable component. When the drain pipe is in the non-drained state, sewage is temporarily stored in the sewage-containing cavity. By setting the drain pipe to a first bending state and the drain outlet being higher than the height of the sewage-containing cavity, sewage in the sewage-containing cavity can be prevented from being discharged to the outside through the drain pipe, thus reducing sewage leakage problems in the non-drained state. In the drain pipe's draining state, the drain outlet is not higher than the height of the sewage-containing cavity. Sewage in the sewage box is discharged to the outside sequentially through the sewage outlet, the sewage-containing cavity, and the drain pipe. During the sewage discharge process, the dirt accumulated in the sewage-containing cavity can be flushed away, thereby automatically cleaning the sewage-containing cavity of the recyclable component. In this disclosure, by using a force-applying unit to change the curvature of the sewage pipe and adjust the height of the sewage outlet, gravitational potential energy is utilized to allow the accumulated dirt and sewage in the sewage-holding chamber to be discharged. This avoids the need for valves or other structures inside the sewage pipe, reducing the risk of pipe blockage. The variation in the sewage outlet height in this disclosure optimizes the sewage discharge effect while effectively reducing the risk of blockage, further improving the reliability and ease of use of the recycling components.

Detailed Implementation

[0042] To make the above-described objects, features, and advantages of this disclosure more apparent and understandable, specific embodiments of this disclosure will be described in detail below with reference to the accompanying drawings. Many specific details are set forth in the following description to provide a thorough understanding of this disclosure. However, this disclosure can be implemented in many other ways different from those described herein, and those skilled in the art can make similar modifications without departing from the spirit of this disclosure. Therefore, this disclosure is not limited to the specific embodiments disclosed below.

[0043] In the description of this disclosure, it should be understood that the terms "center," "longitudinal," "lateral," "length," "width," "thickness," "upper," "lower," "front," "rear," "left," "right," "vertical," "horizontal," "top," "bottom," "inner," "outer," "clockwise," "counterclockwise," "axial," "radial," and "circumferential" indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are used only for the convenience of describing this disclosure and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this disclosure.

[0044] Furthermore, the terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of technical features indicated. Thus, a feature defined as "first" or "second" may explicitly or implicitly include at least one of that feature. In the description of this disclosure, "a plurality of" means at least two, such as two, three, etc., unless otherwise explicitly specified.

[0045] In this disclosure, unless otherwise expressly specified and limited, the terms "installation," "connection," "linking," "fixing," etc., should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral part; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; they can refer to the internal communication of two components or the interaction between two components, unless otherwise expressly limited.

The terms "vertical," "horizontal," "upper," "lower," "left," "right," and similar expressions used herein are for illustrative purposes only and do not represent the only possible implementation.

[0048] In the case of long-term wastewater recycling, the recovery components of cleaning equipment accumulate a significant amount of dirt. These components typically require regular manual cleaning, which is inefficient, time-consuming, and labor-intensive. Delayed cleaning can also lead to leaks or recycling failures. To address this issue, this disclosure provides a cleaning device 100 (… Figure 1 As shown), base station 200 ( Figure 1 (as shown) and cleaning system 1000 ( Figure 1 (As shown).

[0049] Please see Figure 1 The cleaning system 1000 of this disclosure includes a cleaning device 100 of any of the following embodiments and / or a base station 200 of any of the following embodiments.

[0050] Cleaning device 100 is a device used to clean a surface to be cleaned. For example, cleaning device 100 may include a mopping robot and a robot vacuum and mop combo. These two types of robots can be used to wipe and clean the surface to be cleaned. The cleaning device 100 disclosed herein is illustrated using a robot vacuum and mop combo as an example. The surface to be cleaned may be, but is not limited to, a floor, marble surface, carpet, or glass surface. This disclosure uses a floor as an example of a surface to be cleaned.

[0051] Base station 200 is a device for maintaining cleaning equipment 100. For example, base station 200 can clean cleaning equipment 100 and charge it. Furthermore, base station 200 may also have at least one of the following functions: replenishing water to cleaning equipment 100, draining water, and collecting dust. For example, when the power of cleaning equipment 100 is insufficient, cleaning equipment 100 returns to base station 200 to recharge. When cleaning equipment 100 is fully charged, it can leave base station 200 and continue cleaning the surface to be cleaned. When cleaning equipment 100 needs to drain wastewater, it returns to base station 200 to drain the wastewater, and then leaves base station 200 to continue cleaning the surface to be cleaned.

[0052] The cleaning equipment 100 and the base station 200 will be described in detail below with reference to the accompanying drawings.

[0053] Please see Figures 2 to 5 The cleaning equipment 100 includes a cleaning component 22, a wastewater box 24, a recycling component 25, a drain pipe 2518, and a force application unit 258, in any of the following embodiments: a body 10.

[0054] The main body 10 is a component on the cleaning equipment 100 used to mount other components besides the main body 10. Components other than the main body 10, as used herein, include, but are not limited to, the cleaning component 22, the wastewater box 24, the recycling component 25, the drain pipe 2518, and the force application unit 258. Specifically, the cleaning component 22, the wastewater box 24, the recycling component 25, the drain pipe 2518, and the force application unit 258 are mounted on the housing 21. This mounting on the housing 21 means that the housing 21 is mounted to the main body 10 in a detachable or non-detachable manner, and the cleaning component 22, the recycling component 25, the drain pipe 2518, and the force application unit 258 are mounted to the housing 21 in a detachable or non-detachable manner, thereby indirectly mounting the cleaning component 22, the recycling component 25, the drain pipe 2518, and the force application unit 258 on the main body 10. For example, the connection between the housing 21 and the body 10 can also be a movable connection. For instance, the housing 21 can be raised and lowered relative to the body 10 in the height direction Z, and the housing 21 can move relative to the body 10 in the left and right directions. This allows at least the recycling component 25, the drain pipe 2518, and the force application unit 258 to move as a whole along the width direction X of the cleaning equipment 100. The width direction X is the left and right direction, and movement along the width direction of the cleaning equipment 100 includes moving from left to right and from right to left. Here, "left" and "right" refer to... Figure 2 From that perspective.

[0055] Cleaning component 22 is a module on the cleaning device 100 that participates in cleaning the surface to be cleaned by providing dragging force. Combined with... Figure 6 and Figure 9 As shown. In some embodiments, the cleaning component 22 is a tracked cleaning component 22, in which case the cleaning device 100 is a tracked cleaning device. In other embodiments, the cleaning component 22 is a roller-type cleaning component 22, in which case the cleaning device 100 is a roller-type cleaning device. The cleaning component 22 provided in this embodiment only needs to have its rotation axis X parallel to the surface to be cleaned. In addition, the cleaning component 22 specifically includes, but is not limited to, disposable electrostatic mops, disposable wet mops, or reusable fabric mops.

[0056] In some implementations, combined Figure 5The rotation axis X of the cleaning component 22 can be parallel to the surface to be cleaned. In this case, the cleaning surface of the cleaning component 22 rolls on the surface to be cleaned during the cleaning process. Therefore, only part of the cleaning surface of this type of cleaning component 22 contacts the surface to be cleaned during the cleaning process, while another part does not contact the surface to be cleaned. Therefore, this disclosure installs a scraping part 2512 on the cleaning surface of the cleaning component 22 that does not contact the surface to be cleaned. This allows the cleaning surface of the cleaning component 22 to be cleaned in real time while the cleaning component 22 is rotating to clean the floor. That is, after the cleaning component 22 has cleaned part of the surface to be cleaned, it rotates to the scraping part 2512, which can clean that part of the cleaning surface. Then, the cleaning component 22 continues to rotate so that the part of the cleaning surface cleaned by the scraping part 2512 returns to the surface to be cleaned for further cleaning. Thus, as the cleaning component 22 rotates, the cleaning surface on the cleaning component 22 will be cleaned once by the scraping part 2512 with each rotation, making the cleaning surface of the cleaning component 22 that returns to the surface to be cleaned cleaner, thereby making the cleaning of the surface to be cleaned cleaner and more efficient.

[0057] In contrast, traditional disc-type or flat mop-type cleaning devices 22 have their cleaning surfaces completely in contact with the surface to be cleaned. Therefore, there is no space for real-time cleaning of the cleaning surface of the cleaning device 22. Consequently, the existing method for cleaning traditional disc-type or flat mop-type cleaning devices 22 involves the cleaning device 100 returning to the base station 200, where the base station 200 supplies water to the disc-type cleaning device 22 for cleaning. This design means that as the cleaning device 100 cleans the surface, the cleaning device 22 becomes increasingly dirty, requiring frequent returns to the base station 200 to clean it. This can negatively impact the cleaning effect and efficiency of the cleaning device 100.

[0058] It can be seen that, compared with traditional disc-type or flatbed cleaning components 22 (i.e., the axis of rotation is perpendicular to the surface to be cleaned), the track-type cleaning component 22 and the roller-type cleaning component 22 (i.e., the axis of rotation X is parallel to the surface to be cleaned) combined with the setting of the scraping part 2512, have a better cleaning effect and higher efficiency on the surface to be cleaned.

[0059] Wastewater container 24 is a container on the cleaning equipment 100 used to store liquids. It should be noted that the name "wastewater container 24" does not limit the type of liquid it contains; that is, the liquid in wastewater container 24 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 dirt) is within the scope of protection. Wastewater container 24 can be of any shape; for example, the cross-sectional shape of wastewater container 24 can be regular or irregular. In this paper, the cross-sectional shape of wastewater container 24 is irregular. This irregular cross-sectional design allows it to adapt to the structural layout of the cleaning equipment 100, facilitating the compact arrangement of other components.

[0060] The recycling unit 25 is used to temporarily store the wastewater generated by the cleaning unit 22 when cleaning the surface to be cleaned. The wastewater temporarily stored in the recycling unit 25 can enter the wastewater box 24 for storage. The liquid in the wastewater box 24 (which may be clean water or wastewater) can also enter the recycling unit 25 and then be discharged from the recycling unit 25 to the outside of the cleaning equipment 100.

[0061] like Figure 13 As shown, the base station 200 is used for cleaning and maintenance of the cleaning equipment 100. The base station 200 includes a main body 60 and a second force-applying component 67. The main body 60 is the supporting structure for the entire base station 200 and provides mounting positions for other components of the base station 200 (such as the second force-applying component 67). The second force-applying component 67 is mounted on the main body 60 and is used to provide force to the force-receiving component 2585 of the force-applying unit 258. Figure 12 As shown). Figure 6 , Figure 8 As shown, the force-applying unit 258 transmits the force to the sewage pipe 2518, thereby enabling the sewage pipe 2518 to switch between a non-sewage-discharging state and a sewage-discharging state. When the sewage pipe 2518 is in the sewage-discharging state, the cleaning equipment 100 can discharge sewage into the base station 200, preventing dirt and grime from accumulating in the dirt-holding cavity 25115 and the sewage box 24.

[0062] In some embodiments, when the cleaning device 100 returns to the base station 200, and at least the recovery component 25, the drain pipe 2518, and the force application unit 258 mounted on the housing 21 move as a whole along the width direction X of the cleaning device 100 ( Figure 13 (c) When at least a portion of the force-applying unit 258 protrudes relative to the outer contour of the body 10 of the cleaning equipment 100, the second force-applying member 67 abuts against the force-applying unit 25 to apply an external force to the force-applying unit 258. This causes the drain pipe 2518 to switch between a non-drained state and a drained state. The switching process is described below.

[0063] Please see Figures 4 to 9The recycling unit 25 is provided with a sludge-containing cavity 25115 and a wastewater outlet 25116. The wastewater outlet 25116 connects the sludge-containing cavity 25115 and the wastewater box 24. A drain pipe 2518 connects the sludge-containing cavity 25115 and the outside. The drain pipe 2518 is a flexible hose. The drain pipe 2518 includes a drain outlet 25181. The drain pipe 2518 is located at the end of the drain pipe 2518 away from the sludge-containing cavity 25115. A force-applying unit 258 is connected to the drain pipe 2518 and is used to apply a force to the drain pipe 2518 to change the bending state of the drain pipe 2518, so that the drain pipe 2518 switches between a non-drained state and a drained state. Specifically, when the drain pipe 2518 is not in a draining state, the drain pipe 2518 is in a first bend and the position of the drain outlet 25181 is higher than the position of the sludge chamber 25115, so as to prevent the sewage in the sludge chamber 25115 from being discharged to the outside through the drain pipe 2518; when the drain pipe 2518 is in a draining state, the position of the drain outlet 25181 is not higher than the position of the sludge chamber 25115, so as to allow the sewage in the sewage box 24 to be discharged to the outside in sequence through the sewage outlet 25116, the sludge chamber 25115, and the drain pipe 2518.

[0064] Specifically, the recycling component 25 has a dirt-holding cavity 25115 inside, which is used to temporarily store the wastewater generated by the cleaning component 22 during the mopping process. The shape of the dirt-holding cavity 25115 can be cuboid, cylindrical, or other shapes. The dirt-holding cavity 25115 can be divided into a cavity with an open top and a cavity with a closed top. For the cavity with an open top, the recycling component 25 has an opening at the top, allowing the dirt-holding cavity 25115 to communicate directly with the outside, facilitating cleaning of the dirt-holding cavity 25115. For the cavity with a closed top, the recycling component 25 has no opening at the top, forming a completely closed structure at the top of the dirt-holding cavity 25115, which has better sealing performance and can prevent wastewater leakage during the recycling process. When the cleaning device 100 is in the state of mopping the surface to be cleaned, the scraping part 2512 in the recycling component 25 continuously scrapes off the dirt on the cleaning component 22. The dirt includes wastewater and solid waste. The sludge-holding cavity 25115 can hold wastewater, preventing it from re-adhering to the cleaning component 22 or falling onto the surface to be cleaned. The sludge-holding cavity 25115 can temporarily store wastewater, preventing overflow or re-adherence to the cleaning component 22. In some embodiments, the sludge-holding cavity 25115 extends along the rotation axis X of the cleaning component 22, effectively utilizing the internal space of the cleaning equipment 100, reducing cross-interference between the recycling component 25 and the cleaning component 22, and allowing for a more compact layout extending along the rotation axis X of the cleaning component 22, thus avoiding wasted space.

[0065] A wastewater outlet 25116 is provided on the right side of the length direction X of the sludge-containing cavity 25115. The wastewater outlet 25116 is used to connect the sludge-containing cavity 25115 and the wastewater box 24. When the cleaning device 100 is in the state of wiping the surface to be cleaned, the wastewater scraped off by the scraping part 2512 is temporarily stored in the sludge-containing cavity 25115, and the wastewater in the sludge-containing cavity 25115 is connected to the wastewater box 24 through the wastewater outlet 25116. The setting position, setting height, shape and size of the wastewater outlet 25116 can be arbitrarily set, and this disclosure does not limit it. For example, the wastewater outlet 25116 of this disclosure is located above the sludge-containing cavity 25115 in the height direction Z, thereby making full use of the volume of the sludge-containing cavity 25115 to temporarily store wastewater.

[0066] A drain pipe 2518 is used to connect the sludge-containing cavity 25115 to the outside. The drain pipe 2518 includes two opposing ends, one end of which is connected to the sludge-containing cavity 25115, and the other end of the drain pipe 2518 has a drain outlet 25181, which communicates with the sludge-containing cavity 25115, thereby connecting the sludge-containing cavity 25115 to the outside. Figure 9 In the embodiment shown, the drain outlet 25181 is located on the left side of the length direction X of the sludge chamber 25115.

[0067] The hose is a pipe made of a flexible material, including but not limited to rubber, polymer plastics, or other elastic materials. The hose has a certain degree of flexibility and deformability. In some embodiments, the drain pipe 2518 of this disclosure is a hose. The drain pipe 2518 has the ability to change shape; when a force is applied to the drain pipe 2518, it can deform to switch between its bending state and its natural state. The drain pipe 2518 has a natural state when no force is applied; the bending state refers to the degree of deformation (e.g., bending) of the drain pipe 2518 compared to its natural state.

[0068] The force-applying unit 258 is used to apply force to the sewage pipe 2518 to change the bending state of the sewage pipe 2518. That is, the force-applying unit 258 applies forces of different directions and / or magnitudes to the sewage pipe 2518, causing the sewage pipe 2518 to switch between a non-discharged state and a discharged state. The discharged state refers to the state in which sewage in the sludge chamber 25115 can be discharged to the outside through the sewage pipe 2518, and the non-discharged state refers to the state in which sewage in the sludge chamber 25115 cannot be discharged to the outside through the sewage pipe 2518. The position height of the sludge chamber 25115 is the position height of the top of the sludge chamber 25115 in the height direction Z. It is also the highest position that sewage can reach when the sludge chamber 25115 contains sewage. Further, for the sake of brevity in the following description, this disclosure defines the sewage pipe 2518 in the non-discharged state as ( Figures 6 to 8The height of the drain outlet 25181 is the first position height L1. When the drain pipe 2518 is in the draining state, the height of the drain outlet 25181 is the second position height L2. It can be understood that when the recycling component 25 is installed on the cleaning equipment 100, the height of the sludge chamber 25115 remains unchanged.

[0069] Please see Figures 6 to 8 When the drain pipe 2518 is in an undrained state, the force application unit 258 applies a force to the drain pipe 2518. This force is generated through internal components of the force application unit 258, such as through an elastic mechanism, mechanical lever, or other forms of components, providing direct or indirect force transmission. The force maintains the drain pipe 2518 in a first bent state, with the drain outlet 25181 positioned higher than the sludge chamber 25115. The first bent state is one type of bending state of the drain pipe 2518. In this state, the force application unit 258 applies a force to the drain pipe 2518, causing it to deform and maintain the first bent state, thereby keeping the drain outlet 25181 positioned higher than the sludge chamber 25115. That is, in the undrained state, the drain outlet 25181 is positioned above the sludge chamber 25115. Since the height of the sludge-containing cavity 25115 is the highest point that sewage can reach, based on the principle of communicating vessels, the height of the drain outlet 25181 is higher than the highest point that sewage can reach. Sewage will not be discharged to the outside from the upper drain outlet 25181, thus ensuring that sewage can be stored in the sludge-containing cavity 25115 and the sewage box 24. Furthermore, due to gravity and the bending structure, sewage is less likely to overflow or leak from the drain outlet 25181.

[0070] When the force-applying unit 258 changes the force applied to the drain pipe 2518, the drain pipe 2518 switches from a non-draining state to a draining state. When the drain pipe 2518 is in the draining state, the force-applying unit 258 applies a force to the drain pipe 2518. It is understood that the force applied in the draining state is different from the force applied in the non-draining state, and this difference includes, but is not limited to, differences in the direction and / or magnitude of the force. The change in force causes a change in the position height of the drain outlet 25181. In the draining state, the position height of the drain outlet 25181 is not higher than the position height of the sludge chamber 25115. The force-applying unit 258 applies a force to the drain pipe 2518 to maintain the drain outlet 25181 at a position height not higher than the sludge chamber 25115. That is, in the draining state, the position height of the drain outlet 25181 is the same as or below the position height of the sludge chamber 25115. Since the height of the sludge-containing chamber 25115 is the highest point that sewage can reach, and the height of the drain outlet 25181 is no higher than the highest point that sewage can reach, the sewage in the sewage box 24 can flow from the drain outlet 25116 into the sludge-containing chamber 25115 under the influence of gravitational potential energy, then flow from the sludge-containing chamber 25115 into the drain pipe 2518, and finally be discharged to the outside from the drain outlet 25181. For example, after the cleaning component 22 completes its cleaning work, the recycling component 25 may be in an un-drained state. Alternatively, during the cleaning process of the cleaning component 22, if the sewage in the sewage box 24 and / or the sludge-containing chamber 25115 reaches a certain preset value, and the cleaning equipment 100 needs to discharge sewage to continue working, the recycling component 25 may need to be drained. The preset value can be a preset volume, a preset mass, a preset drainage time, etc. The force application unit 258 applies force to the sewage pipe 2518 through compression, tension, or rotation to switch the sewage pipe 2518 from a non-discharge state to a discharge state. The sewage flows out to the outside using gravitational potential energy, which also reduces discharge time and energy consumption.

[0071] In some embodiments, when the force-applying unit 258 changes the force applied to the drain pipe 2518, the drain pipe 2518 can switch between a non-drained state and a non-drained state. The force-applying unit 258 can be a motor or a purely mechanical structure; the purely mechanical structure is less expensive than the motor method.

[0072] The cleaning device 100 disclosed herein adjusts the force applied to the drain pipe 2518 by setting a force application unit 258, thereby changing the bending state of the drain pipe 2518 and enabling the drain pipe 2518 to switch between a non-drained state and a drained state, thus realizing the drain function of the drain pipe 2518. In the non-drained state, since sewage is temporarily stored in the sludge chamber 25115, by setting the drain pipe 2518 to a bent state with the drain outlet 25181 facing upward, the sewage in the sludge chamber 25115 can be prevented from being discharged to the outside through the drain pipe 2518, thereby reducing the sewage leakage problem in the non-drained state. In the drained state, the sewage in the sewage box 24 is discharged to the outside through the sewage outlet 25116, the sludge chamber 25115, and the drain pipe 2518 in sequence. During the sewage discharge process, the dirt accumulated in the sludge chamber 25115 can be flushed out, thereby achieving the function of automatically cleaning the sludge chamber 25115 of the recovery component 25. In this disclosure, by using the force application unit 258 to change the bending state of the drain pipe 2518 and adjust the height of the drain outlet 25181, the accumulated dirt and sewage in the sludge chamber 25115 can be discharged using gravitational potential energy. This significantly improves the cleaning efficiency of the recycling component 25 and prevents dirt accumulation in the recycling component 25. In this disclosure, no components are installed inside the drain pipe 2518; the risk of blockage in the drain pipe 2518 can be reduced simply by adjusting the relative height of the drain outlet 25181 and the sludge chamber 25115.

[0073] Please see Figure 4 , Figures 9 to 11 , Figure 13 (a) In one embodiment, when the drain pipe 2518 is in the draining state, the drain pipe 2518 is in a straight line and the drain outlet 25181 is at the same height as the sewage chamber 25115.

[0074] Specifically, in the straight state, the drain pipe 2518 changes its bending state under the force of the force application unit 258, and the drain pipe 2518 is straightened. The drain outlet 25181 and the sludge chamber 25115 are at the same height. For example, the center of the drain outlet 25181 is located on the extension line of the axis of the sludge chamber 25115. In the straight state, the drain pipe 2518 is in a straight shape, and the sewage outlet 25116, the sludge chamber 25115, the drain pipe 2518, and the drain outlet 25181 form a smooth sewage discharge channel. Sewage flows out of the drain outlet 25181 to the outside by relying on the gravitational potential energy or the force when it comes out of the sewage box 24. This ensures that sewage can be discharged in the sewage discharge state, reduces the residence time of sewage in the sludge chamber 25115 and the sewage box 24, and avoids the accumulation of dirt in the sludge chamber 25115 and the sewage box 24. The dirt is a substance formed when suspended particles in sewage adhere to the sludge chamber 25115 and the sewage box 24.

[0075] Please see Figure 4, Figures 9 to 11 , Figure 13 (d) In another embodiment, when the drain pipe 2518 is in the draining state, the drain pipe 2518 is in the second bending state and the position height of the drain outlet 25181 is lower than the position height of the sludge chamber 25115.

[0076] Specifically, the so-called second bend refers to the position of the sewage outlet 25181 being lower than the position of the sludge chamber 25115. As a result, sewage can flow out naturally under the influence of gravity, reducing drainage resistance. In addition, the sewage pipe 2518 is in the second bend state during sewage discharge, which can prevent sewage backflow and avoid sewage flowing back into the sludge chamber 25115.

[0077] Please see Figure 4 , Figure 13 (a) Figure 13 (c) In some embodiments, the drain pipe 2518 is in a straight line in its natural state.

[0078] Specifically, the natural state refers to the state of the drain pipe 2518 when it is not subjected to any force, that is, the state formed by the material and structural characteristics of the drain pipe 2518 itself. The drain pipe 2518 is in a straight state in its natural state, while it is in a first bent state when it is not discharging sewage. Therefore, the drain pipe 2518 in the non-discharging state has a tendency to return to its natural state from the first bent state. When the drain pipe 2518 switches from the non-discharging state to the discharging state, it can switch the state by using the force applied to the drain pipe 2518 by the force application unit 258, and by using the reset force generated by the drain pipe 2518 when it returns to its natural state. This improves the response speed of the drain pipe 2518 when switching from the non-discharging state to the discharging state.

[0079] Please see Figures 3 to 11 In some embodiments, when the drain pipe 2518 is not draining, the angle between the central axis of the drain outlet 25181 extending away from the sludge chamber 25115 and the height direction of the cleaning device 100 from bottom to top is zero or an acute angle. When the drain pipe 2518 is draining, the angle between the central axis of the drain outlet 25181 extending away from the sludge chamber 25115 and the height direction of the cleaning device 100 from bottom to top is greater than or equal to 90°.

[0080] Specifically, when the sewage pipe 2518 is in a state of not discharging sewage ( Figures 6 to 8 , Figure 13(b) The angle between the central axis of the drain outlet 25181 extending away from the sludge chamber 25115 and the height direction of the cleaning device 100 from bottom to top is zero or acute, so that the drain outlet 25181 is basically aligned with the height direction Z of the cleaning device 100. This helps to make the drain outlet 25181 face upward as much as possible, thereby effectively utilizing the natural flow of gravity and reducing the possibility of sewage leakage from the drain outlet 25181.

[0081] When the sewage pipe 2518 is in the sewage discharge state ( Figures 9 to 11 , Figure 13 (a) Figure 13 (c) Figure 13 (d) The angle between the central axis of the drain outlet 25181 extending away from the sludge chamber 25115 and the height direction of the cleaning device 100 from bottom to top is greater than or equal to 90°. When the angle is greater than 90°, such as Figure 13 As shown in (d), the sewage flow path better conforms to the natural direction of gravity drainage. Sewage can naturally flow out of the drain pipe 2518 to the outside using its own gravity, avoiding sewage blockage or backflow into the drain pipe 2518. This improves the sewage discharge efficiency of the cleaning equipment 100 and reduces the possibility of sewage residue.

[0082] Please see Figure 4 In some embodiments, the drain pipe 2518 is in a conductive state whether it is in a non-draining state or a draining state.

[0083] Specifically, in related technologies, if the sewage pipe is in a conductive state, a switch is needed to switch the conductive and non-conductive states of the sewage pipe. Furthermore, the use of a switch requires additional sealing components to ensure that sewage does not leak when the sewage pipe 2518 is in a non-conductive state, further increasing the manufacturing cost of the cleaning equipment 100. In this disclosure, the sewage pipe 2518 is always in a conductive state, eliminating the need for additional switches and sealing components. This simplifies the structure of the cleaning equipment 100, reduces the mechanical wear of the switch and the need for sealing maintenance, improves the durability and reliability of the cleaning equipment 100, and lowers the manufacturing and maintenance costs of the cleaning equipment 100. Moreover, since the sewage pipe 2518 is always in a conductive state, system failures caused by mechanical switch jamming or failure are avoided.

[0084] Please see Figure 4 and Figure 5 In some embodiments, the recycling member 25 further includes a scraping portion 2512. The scraping portion 2512 abuts against the cleaning member 22, and at least a portion of the dirt-containing cavity 25115 is lower than the scraping portion 2512. During the rotation of the cleaning member 22, the scraping portion 2512 peels dirt off the cleaning member 22.

[0085] During the movement of the cleaning device 100, the scraping part 2512 is used to scrape off dirt from the cleaning component 22. The scraping part 2512 abuts against the cleaning component 22 to peel the dirt off the cleaning component 22. In the direction of travel of the cleaning device 100, the scraping part 2512 abuts against the cleaning component 22. As the cleaning component 22 rotates, the scraping part 2512 continuously scrapes dirt off the cleaning surface of the cleaning component 22 and guides wastewater into the dirt-holding chamber 25115, thereby maintaining the cleaning effect of the cleaning component 22, reducing dirt accumulation, and extending the service life of the cleaning component 22. In the height direction Z of the cleaning device 100, at least a portion of the dirt-holding cavity 25115 is lower than the scraping part 2512. That is, at least a portion of the dirt-holding cavity 25115 is positioned below the scraping part 2512 in the height direction Z of the cleaning device 100. This allows for natural drainage of wastewater using gravity, ensuring that wastewater flows smoothly into the dirt-holding cavity 25115, preventing wastewater overflow, and preventing secondary contamination of the surface to be cleaned. After the scraping part 2512 removes wastewater from the cleaning surface of the cleaning component 22, the wastewater flows directly into the lower-positioned dirt-holding cavity 25115 through the filter part 2513. This prevents wastewater from accumulating around the scraping part 2512 and reduces the possibility of wastewater re-adhering to the cleaning component 22. The bottom surface of the dirt-holding cavity 25115 can be inclined or conical to further guide the wastewater.

[0086] Please see Figure 4 and Figure 5 In some embodiments, the filter section 2513 is positioned higher than the scraper section 2512. The filter section 2513 is provided with filter holes 25131, which connect the outside to the sludge chamber 25115, allowing wastewater in the sludge to enter the sludge chamber 25115 and blocking solid waste in the sludge from entering the sludge chamber 25115.

[0087] The filter section 2513 is used to separate dirt generated by the cleaning component 22 during the cleaning process. Since dirt on the ground includes not only wastewater but also solid waste, it adheres to the cleaning component 22, forming dirt. The filter section 2513 allows wastewater from the dirt to flow into the dirt-holding chamber 25115, while preventing larger solid waste from entering the dirt-holding chamber 25115 (wastewater recycling link). The filter section 2513 has filter holes 25131, which connect the outside to the dirt-holding chamber 25115. In one example, the filter section 2513 is a filter screen located between the dirt-holding chamber 25115 and the outside, and has multiple filter holes 25131. The size of the filter holes 25131 can be set as needed, only requiring that wastewater can pass through while larger solid waste cannot. When the cleaning device 100 is in the state of wiping the surface to be cleaned, the dirt scraped off by the scraper 2512 includes sewage and solid waste mixed with sewage. The sewage can flow into the dirt-holding chamber 25115 through the filter 2513 for storage, preventing sewage from re-adhering to the cleaning component 22. Solid waste is blocked by the filter 2513 and remains on the cleaning surface of the cleaning component 22, thereby preventing solid waste from entering the dirt-holding chamber 25115 and even further blocking the sewage pipe 257 connected to the dirt-holding chamber 25115. For example, as the cleaning device 100 moves from the rear to the front, the cleaning component 22 rotates downward relative to the scraper 2512. The dirt scraped off by the scraper 2512 gathers above the scraper 2512 and has a certain upward tendency. The filter 2513 is positioned higher than the scraper 2512, making it convenient for the dirt to pass directly through the filter 2513 and enter the dirt-holding chamber 25115 after being scraped off by the scraper 2512. In addition, in some embodiments, a sludge-holding chamber 25115 may be provided above the filter section 2513. In this way, when the cleaning device 100 is flipped, the sludge-holding chamber 25115, which was originally located above, is in a lower state, so that the sewage that was originally located in the lower sludge-holding chamber 25115 can flow into the upper sludge-holding chamber 25115, thereby preventing sewage from overflowing or polluting the environment.

[0088] Please see Figures 4 to 11In some embodiments, the force-applying unit 258 includes a transmission member 2581, a reset member 2583, and a force-receiving member 2585. The first end 25811 of the transmission member 2581 is connected to the drain pipe 2518. The reset member 2583 includes a fixed end 25832 and a movable end 25831; the fixed end 25832 is connected to the housing of the cleaning equipment 100, and the movable end 25831 of the reset member 2583 is connected to the second end 25812 of the transmission member 2581. The reset member 2583 has a first state and a second state. When the reset member 2583 is in the first state, it drives the transmission member 2581 to keep the drain pipe 2518 in a non-drainage state. When the reset member 2583 is in the second state, it drives the transmission member 2581 to keep the drain pipe 2518 in a drainage state. The force-receiving component 2585 is connected to the movable end 25831 of the reset component 2583. The force is applied to the force-receiving component 2585 so that the reset component 2583 can switch between the first state and the second state.

[0089] Specifically, the transmission component 2581 is disposed between the drain pipe 2518 and the reset component 2583, and is used to transmit the force of the reset component 2583 to control the bending state of the drain pipe 2518. The first end 25811 of the transmission component 2581 is fixedly connected to the drain pipe 2518, and the second end 25812 of the transmission component 2581 is connected to the movable end 25831 of the reset component 2583. The connection includes direct connection and indirect connection. Direct connection means that the second end 25812 of the transmission component 2581 is directly connected to the movable end 25831 of the reset component 2583. Indirect connection means that the second end 25812 of the transmission component 2581 is indirectly connected to the movable end 25831 of the reset component 2583 through other components (such as the force-receiving component 2585), that is, one end of the force-receiving component 2585 is connected to the second end 25812 of the transmission component 2581, and the other end of the force-receiving component 2585 is connected to the movable end 25831 of the reset component 2583. Direct connections are simple and fast-responding, while indirect connections offer greater flexibility and are suitable for applications with limited space or requiring intermediate transmission structures. Furthermore, when the transmission component 2581 receives the force from the reset component 2583, it can transmit the force from the reset component 2583 to the drain pipe 2518, allowing the drain pipe 2518 to switch between a draining state and a non-draining state. In addition, in Figure 4In the illustrated embodiment, the drain pipe 2518 is located on the left side of the cleaning device 100, the reset member 2583 is located on the right side of the cleaning device 100, and the transmission member 2581 connects the components on both sides, which facilitates the layout of the components in the cleaning device 100. Exemplarily, the transmission member 2581 in this disclosure can be a steel wire rope. Steel wire ropes have characteristics such as high strength, strong wear resistance, and good flexibility. Therefore, when the transmission member 2581 receives the force from the reset member 2583, it can smoothly transmit the force, while also preventing damage to the force-applying unit 258 due to excessive force.

[0090] Under external force, the reset member 2583 can switch between a first state and a second state, thereby driving the drain pipe 2518 to switch between a non-drainage state and a drainage state. The reset member 2583 includes a fixed end 25832 and a movable end 25831. The fixed end 25832 is connected to the housing of the cleaning equipment 100, and the movable end 25831 is connected to the second end 25812 of the transmission member 2581. Exemplarily, the reset member 2583 in this disclosure can be a spring. The spring has elastic force and can switch between the first state and the second state under the action of external force, thereby driving the drain pipe 2518 to switch between a drainage state and a non-drainage state. Moreover, the spring has a simple structure and low cost. When the reset member 2583 is in the first state, the reset member 2583 drives the transmission member 2581 to pull the drain pipe 2518 to the non-drainage state. At this time, the drain pipe 2518 is in a first bent state, and sewage will not be discharged from the drain pipe 2518. When the reset component 2583 is in the second state, the reset component 2583 drives the transmission component 2581 to put the sewage pipe 2518 in the sewage discharge state, and the sewage can flow out smoothly from the sewage outlet 25181.

[0091] The force-receiving member 2585 is used to receive external forces (such as the force generated by the second force-applying member 67) and transmit the external forces to the reset member 2583, thereby causing the reset member 2583 to be in a first state (see [link]). Figure 11 ) and the second state (see Figure 8 The force-receiving component 2585 can be a button, lever, or sliding mechanism, etc. Taking a button as an example, the force-receiving component 2585 is a press-type structure that is easy to operate, and can directly transmit external force to the movable end 25831 of the reset component 2583 when pressed. When external force is applied to the force-receiving component 2585, the force-receiving component 2585 applies external force to the movable end 25831 of the reset component 2583, causing the reset component 2583 to switch from the first state to the second state. After the external force is removed, the reset component 2583 switches back from the second state to the first state.

[0092] In the above embodiments, the force application unit 258 is entirely implemented by a mechanical structure, which greatly reduces costs.

[0093] Please see Figures 4 to 11In some embodiments, when the drain pipe 2518 is in a non-draining state, the force-bearing member 2585 is not subjected to external force. When the drain pipe 2518 is in a draining state, the force-bearing member 2585 is continuously subjected to external force.

[0094] Specifically, the cleaning equipment 100 is mostly in a non-operating state, meaning the drain pipe 2518 is mostly in a non-draining state. Therefore, in the non-draining state, the load-bearing component 2585 is not subjected to external force, preventing it from being under constant stress and reducing wear and fatigue, thus extending its service life. When the drain pipe 2518 is in the draining state, the load-bearing component 2585 is continuously subjected to external force. This continuous force keeps the drain pipe 2518 in the draining state, allowing wastewater to continuously flow to the outside. The application of this external force controls whether the drain pipe 2518 is in the draining state, simplifying the overall structure of the cleaning equipment 100.

[0095] Please see Figures 4 to 11 In some embodiments, the reset member 2583 is an elastic member, which is in a natural state or in a first compressed state in the first state (see [reference]). Figure 8 In the second state, the elastic element is in the second compression state (see [link]). Figure 11 The degree of compression in the first compression state is less than that in the second compression state.

[0096] Specifically, the first compression state is when the reset member 2583 is slightly compressed, meaning it has not fully released its elasticity or is only compressed to a certain extent. In this first state, the reset member 2583 provides tension to the drain pipe 2518 to maintain it in a non-drainage state, thus preventing sewage leakage. The second state is when the reset member 2583 is further compressed, to a degree greater than the first compression state. When the force-bearing member 2585 is continuously subjected to external force, the reset member 2583 remains in the second compression state to maintain the drain pipe 2518 in a drainage state. In the second compression state, the reset member 2583 stores more elastic potential energy than in the first state, and it tends to switch from the second state to the first state. When the external force is removed, the reset member 2583 returns to the first state under its elastic potential energy. The reset member 2583 then exerts tension on the drain pipe 2518 through the transmission member 2581, pulling the drain pipe 2518 from the drainage state to the non-drainage state. For example, when the reset member 2583 returns from the second state to the first state, the reset member 2583 applies a pull force to the drain pipe 2518 through the transmission member 2581, pulling the drain pipe 2518 to rotate from left to right, thus resetting the drain pipe 2518 to the non-drainage state. The pull force can both complete the reset of the reset member 2583 and reduce the impact on other components when the elastic member is suddenly released.

[0097] In some embodiments, the reset member 2583 is an elastic member. In the first state, the elastic member is in a natural state or in a first stretched state. In the second state, the elastic member is in a second stretched state. The degree of stretching in the first stretched state is less than the degree of stretching in the second stretched state.

[0098] Specifically, the first stretched state is when the reset member 2583 is in a slightly stretched state, meaning that the reset member 2583 has not fully released its elasticity or is only stretched to a certain extent. In the first state, the reset member 2583 can provide tension to the drain pipe 2518 to maintain the drain pipe 2518 in a non-drainage state, thereby preventing sewage leakage. The second state is when the reset member 2583 is further stretched, with a stretching degree higher than the first stretched state. When the force-bearing member 2585 is continuously subjected to external force, the reset member 2583 remains in the second stretched state to maintain the drain pipe 2518 in the drainage state. In the second stretched state, the reset member 2583 stores more elastic potential energy than in the first state, and the reset member 2583 has a tendency to switch from the second state to the first state. When the external force is removed, the reset member 2583 returns to the first state under the elastic potential energy, and the reset member 2583 generates tension on the drain pipe 2518 through the transmission member 2581, pulling the drain pipe 2518 from the drainage state to the non-drainage state. For example, when the reset member 2583 returns from the second state to the first state, the reset member 2583 applies a pull force to the drain pipe 2518 through the transmission member 2581, pulling the drain pipe 2518 to rotate from left to right, thus resetting the drain pipe 2518 to the non-drainage state. The pull force can both complete the reset of the reset member 2583 and reduce the impact on other components when the elastic member is suddenly released.

[0099] In some implementations, such as Figure 13 As shown, when the drain pipe 2518 switches between a non-draining state and a draining state, the force-bearing component 2585 switches between a first position and a second position along the extension direction of the transmission component 2581. The stroke between the first position and the second position is greater than or equal to a first distance. The first distance is the difference between the height of the connection between the transmission component 2581 and the drain pipe 2518 in the non-draining state and the height of the axis of the drain pipe 2518 in the straight state.

[0100] Specifically, when an external force is applied to the force-receiving component 2585, the force-receiving component 2585 switches between a first position and a second position along the extension direction of the transmission component 2581. The extension direction of the transmission component 2581 refers to its length direction X. When the force-receiving component 2585 is in the first position, the drain pipe 2518 is in an undrained state, and at this time the drain pipe 2518 is in a first bent state; when the force-receiving component 2585 is in the second position, the drain pipe 2518 is in a draining state, and at this time the drain pipe 2518 is in a straight state or a second bent state. Figure 13d) The switching from the first position to the second position occurs when the force-receiving component 2585 is pushed by an external force. This external force is transmitted through the force-receiving component 2585 to the transmission component 2581, thereby applying a pushing or pulling force to the drain pipe 2518, gradually straightening it from a bent state. When the external force is removed, the reset component 2583 releases its stored elastic potential energy, pushing the force-receiving component 2585 back from the second position to the first position. Simultaneously, the transmission component 2581 restores the drain pipe 2518 to its bent state. The stroke between the first and second positions is greater than or equal to the first distance, ensuring complete switching of the drain pipe 2518 between the two states, avoiding incomplete operation due to insufficient stroke, and improving the stability and reliability of the drain device.

[0101] When the recycling component 25 is in the discharge state, the force-receiving component 2585 is in the first position and is continuously subjected to external forces other than those from the cleaning equipment 100. One source of the external force can be the second force-applying component 67 in the base station 200. The second force-applying component 67 applies external force to the force-receiving component 2585 through the force-applying unit 2588, and transmits the force to the discharge pipe 2518 through the force-receiving component 2585 and the transmission component 2581. Specifically, the external force applied by the second force-applying component 67 can be divided into two states: a first external force and a second external force. When the second force-applying component 67 applies the first external force, the force-receiving component 2585 is in the second position, and the transmission component 2581 keeps the discharge pipe 2518 in a non-discharge state through the transmission of force. When the second force-applying component 67 applies a larger second external force, the force-receiving component 2585 moves to the first position, and the transmission component 2581 applies a pushing or pulling force to the discharge pipe 2518, causing the discharge pipe 2518 to switch to the discharge state. When the external force gradually decreases from the second external force to the first external force or disappears completely, the elastic potential energy of the reset member 2583 drives the force-bearing member 2585 to return to the second position, and restores the drain pipe 2518 to the bent state through the transmission member 2581.

[0102] In some embodiments, such as Figure 13 (a) Figure 13 As shown in (c), the external force can be applied by the second force-applying component 67 actively triggering the force-receiving component 2585, or by the recovery component 25, the sewage pipe 2518, and the force-applying unit 258 moving together in the width direction so that the force-receiving component 2585 in the force-applying unit 258 can actively contact the second force-applying component 67 of the base station 200 and generate a force on the force-receiving component 2585.

[0103] Please see Figures 4 to 8 In some embodiments, when the drain pipe 2518 is a flexible hose and the hose is bent with the drain outlet facing upward in its natural state (i.e., the first bent state), the transmission member 2581 is a rigid transmission member. The first end 25811 of the rigid transmission member is connected to the drain pipe 2518, and the second end 25812 of the rigid transmission member is connected to the movable end 25831 of the reset member 2583.

[0104] Specifically, when the drain pipe 2518 is a flexible hose and the hose is bent with the drain outlet facing upwards in its natural state, the transmission component 2581 is a rigid transmission component. The rigid structure of the rigid transmission component can change the bending shape of the hose under the action of external force, and change the bending angle of the hose through physical force, thereby controlling the sewage discharge action of the drain pipe 2518.

[0105] like Figure 13 As shown, when switching to the straight state of the drain pipe 2518, the rigid transmission component 2581 can transmit thrust from right to left, allowing the hose to overcome the resistance of its curved shape, straighten, and align with the sludge chamber 25115 or the drain outlet facing downwards. The advantage of the rigid transmission component 2581 is that its rigidity ensures the directionality and integrity of force transmission. Both tensile and thrust forces can act on the connection points of the drain pipe 2518, reducing force loss caused by deformation and improving the reliability and efficiency of the drain operation.

[0106] In contrast, when the hose's natural state is either straight or curved with the drain outlet 25181 facing downwards (second curved state), a flexible transmission component 2581 can be selected. The elasticity of the flexible transmission component 2581 allows it to adapt to certain deformations during force transmission, enabling more flexible engagement with the drain pipe 2518. In this case, when tension is applied to the flexible transmission component 2581, the force of the reset component 2583 pulls the drain pipe 2518 from left to right; under external force, the reset component 2583 is compressed or stretched, allowing the flexible transmission component 2581 to release the tension on the drain pipe 2518, causing the hose to return to its natural state. The advantage of the flexible transmission component 2581 is that its flexible connection can alleviate the mechanical stress on the reset component 2583 and the drain pipe 2518, extending their lifespan, while also providing more design freedom in structural layout.

[0107] Please see Figures 4 to 7 In some embodiments, the force-applying unit 258 further includes a first protective member 2587. The first protective member 2587 is installed on the drain pipe 2518. In the non-drained state, the first protective member 2587 at least covers the side of the drain pipe 2518 that is closer to the cleaning equipment 100.

[0108] Specifically, the first protective element 2587 is used to increase the structural strength of the drain pipe 2518. The drain pipe 2518 is at least partially housed within the first protective element 2587 to protect it. The first protective element 2587 can be made of plastic or metal. When the first protective element 2587 is made of plastic, it has good insulation performance, low cost, and light weight. When the first protective element 2587 is made of metal, it has high strength, good wear resistance, and a long service life. The first protective element 2587 provides protection for the side of the drain pipe 2518 that is closer to the cleaning equipment 100 during the draining process, preventing the cleaning equipment 100 from bumping into the drain pipe 2518 during movement, thereby ensuring that the internal structure of the cleaning equipment 100 is protected from contamination or corrosion. The first protective element 2587 covers the side of the drain pipe 2518 that faces the cleaning equipment 100 and is closer to the drain pipe 2518. The opposite area of ​​the side is empty to facilitate the installation of the transmission element 2581.

[0109] Please see Figures 4 to 7 In some embodiments, a second protective member 25872 covers the surface of the drain pipe 2518 where the drain outlet 25181 is located.

[0110] Specifically, the second protective member 25872 covers the surface of the drain pipe 2518 where the drain outlet 25181 is located. The second protective member 25872 is used to strengthen the structural strength of the surface where the drain outlet 25181 is located, preventing deformation and damage to the drain outlet 25181. For example, the connection between the second protective member 25872 and the first protective member 2587 enhances the overall structural strength. Furthermore, the covering design of the second protective member 25872 prevents foreign objects from clogging the drain outlet 25181, ensuring smooth drainage.

[0111] Please see Figure 4 and Figure 10 In some embodiments, the force-applying unit 258 further includes a fixing seat 2588, which is disposed on the outer wall of the drain pipe 2518; the fixing seat 2588 is provided with a rotating shaft 25875, and the transmission component 2581 is connected to the rotating shaft 25875.

[0112] Specifically, the fixed base 2588 is used to connect the rotating component, and is rotatably connected to the transmission component 2581 via the rotating shaft 25875, protruding relative to the drain pipe 2518. The protruding design of the fixed base 2588 provides additional space to accommodate the rotational needs of the drain pipe 2518 and the transmission component 2581, and achieves a rotatable connection with the transmission component 2581 via the rotating shaft 25875, thereby supporting flexible switching of the drain pipe 2518 between different states. For example, the first end 25811 of the transmission component 2581 near the rotating shaft 25875 can be a ring, sleeved on the rotating shaft 25875. This design is simple and easy to manufacture, and effectively prevents the transmission component 2581 from breaking due to concentrated force. Furthermore, the protruding structure of the fixed base 2588 further prevents external forces from directly acting on the drain pipe 2518, improving the safety and reliability of the cleaning equipment 100 operation.

[0113] Please see Figure 4 In some embodiments, the recycling unit 25 further includes a wastewater box 24, a wastewater pipe 257, and a power unit 34. One end of the wastewater pipe 257 is connected to the sludge chamber 25115 via a wastewater outlet 25116, and the other end is connected to the wastewater box 24. The power unit 34 is connected to the wastewater box 24 and is used to provide negative pressure to the wastewater box 24 to draw wastewater from the sludge chamber 25115 into the wastewater box 24 through the wastewater outlet 25116, and to provide positive pressure to the wastewater box 24 so that the wastewater in the wastewater box 24 is discharged to the outside through the wastewater pipe 257, the sludge chamber 25115, and the drain pipe 2518.

[0114] As previously described, the wastewater box 24 is a container for storing liquids, and the recycling unit 25 is used to temporarily store wastewater generated by the cleaning unit 22 during cleaning of the surface to be cleaned. The power unit 34 is a device for pumping wastewater from the sludge chamber 25115 into the wastewater box 24 through the wastewater pipe 257, and for discharging wastewater from the wastewater box 24 into the sludge chamber 25115 through the wastewater pipe 257. In some embodiments, the power unit 34 includes a gas-liquid mixing pump, that is, the power unit 34 is both a water pump for pumping or draining water and a gas pump for creating negative pressure or creating positive pressure. When the power unit 34 is turned on and creates negative pressure in the wastewater box 24, the wastewater in the sludge chamber 25115 will enter the wastewater pipe 257 through the wastewater outlet 25116 and then enter the wastewater box 24 for storage. It is understood that the power unit 34 is activated when the cleaning device 100 is wiping the surface to be cleaned. Activation methods include, but are not limited to, continuous activation following the cleaning device 100, intermittent activation based on the working time of the cleaning component 22, and intermittent activation based on the volume of wastewater in the sludge chamber 25115. In some embodiments, the power unit 34 is connected to the wastewater box 24 to provide positive pressure to the wastewater box 24, causing the wastewater in the wastewater box 24 to be discharged into the sludge chamber 25115 through the wastewater pipe 257. When the cleaning device 100 is in the wastewater discharge state, the power unit 34 can first vent air into the wastewater box 24 to provide positive pressure. Under the action of positive pressure, the wastewater in the wastewater box 24 flows into the sludge chamber 25115 through the wastewater pipe 257 and is finally discharged to the base station 200 from the drain pipe 2518.

[0115] The embodiments described above are merely illustrative of several implementations of this disclosure, and while the descriptions are 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 disclosure, and these all fall within the scope of protection of this disclosure. Therefore, the scope of protection of this patent should be determined by the appended claims.
