[0133] Exemplary embodiments will now be described more fully with reference to the accompanying drawings. However, these exemplary embodiments can be implemented in many forms and should not be construed as limited to the embodiments set forth herein; rather, they are provided so that this disclosure will be thorough and complete, and will fully convey the concept of the exemplary embodiments to those skilled in the art. The same reference numerals in the drawings denote the same or similar structures, and therefore their detailed description will be omitted.

[0134] Although relative terms such as "up" and "down" are used in this specification to describe the relative relationship of one component of an icon to another, these terms are used only for convenience, such as according to the orientation of the examples shown in the accompanying drawings. It is understood that if the device of the icon is flipped upside down, the component described as "up" will become the component described as "down." When a structure is "up" of another structure, it may mean that the structure is integrally formed on the other structure, or that the structure is "directly" mounted on the other structure, or that the structure is "indirectly" mounted on the other structure through another structure.

[0135] The terms “a,” “one,” “the,” and “the” are used to indicate the existence of one or more elements / components / etc.; the terms “including” and “having” are used to indicate an open-ended inclusion meaning and that there may be other elements / components / etc. in addition to the listed elements / components / etc.; the terms “first” and “second” are used only as markers and are not a limitation on the number of objects.

[0136] As shown in Figures 1 to 23, some embodiments provide a container 012, in which the upper cover assembly and the container body are easily separated, facilitating the disassembly of the upper cover assembly and improving the user experience. The container 012 can be used to hold wastewater, but is not limited thereto. It can also be used to hold clean water, cleaning fluid, sewage, dust, solid-liquid mixtures, etc., so that it can function as both a supply container and a waste container, selectable and configured according to actual needs. This container 012 can be applied to cleaning equipment 01. Cleaning equipment 01 can be a floor scrubber, a robotic vacuum cleaner, a vacuum and mop combo, etc., and this disclosure does not impose specific limitations on it.

[0137] The container 012 may include: a top cover assembly 1, a container body 2, and a first unlocking assembly 3. The container body 2 may have a receiving cavity 21, which can be used to hold clean water, cleaning fluid, sewage, dust, solid-liquid mixtures, etc.

[0138] When the cover assembly 1 and the housing 2 are in the installed state, at least part of the cover assembly 1 can be located within the receiving cavity 21. For example, when the cover assembly 1 and the housing 2 are in the installed state, the side wall 22 of the housing 2 can be detachably connected to the cover assembly 1.

[0139] Optionally, when the top cover assembly 1 and the housing 2 are in the installed state, the side wall 22 of the housing 2 and the top cover assembly 1 can be interference-fitted. That is, the side wall 22 of the housing 2 and the top cover assembly 1 can be connected by an interference fit. This arrangement can ensure a high connection strength between the housing 2 and the top cover assembly 1 while facilitating the user's installation and disassembly of the housing 2 and the top cover assembly 1. However, it is not limited to this; the top cover assembly 1 and the housing 2 can also be connected by adhesive, snap-fit, or other methods, which are also within the scope of protection of this disclosure.

[0140] The housing 2 may have an open end 25, that is, it is understood that the receiving cavity 21 can be exposed through the open end 25. A portion of the top cover assembly 1 may be located within the receiving cavity 21 through the open end 25, and another portion of the support assembly may be used to seal the open end 25 so that the receiving cavity 21 is a closed chamber.

[0141] The first unlocking component 3 can be installed on the top cover component 1 and / or the housing 2. The first unlocking component 3 may include an actuator 31 and a first trigger 32. When the top cover component 1 and the housing 2 are in the installed state, the first trigger 32 can be in the initial position. The first unlocking component 3 can be configured to cause the actuator 31 to perform a first movement, thereby driving the first trigger 32 to push the housing 2 and / or the top cover component 1, thus separating the top cover component 1 from the housing 2. With this configuration, when it is necessary to remove the top cover component 1 from the housing 2, the user can complete the separation operation by actuating the actuator 31 to perform the first movement. Therefore, compared with the prior art, the housing 012 provided by this disclosure allows for easier separation of the top cover component 1 and the housing 2, facilitating the disassembly of the top cover component 1, thereby reducing the user's workload and improving the user experience.

[0142] Furthermore, the first unlocking component 3 can be configured to cause the actuator 31 to perform a second movement, thereby driving the first trigger 32 back to its initial position, thus preparing for the next separation operation of the housing 2 and the top cover assembly 1, so that the separation operation of the housing 2 and the top cover assembly 1 can be repeated.

[0143] Optionally, when the top cover assembly 1 and the housing 2 are in the installed state, the side wall 22 of the housing 2 is detachably connected to the top cover assembly 1. When the actuator 31 performs the first movement, it can cause the first trigger 32 to provide a force to the housing 2 and / or the top cover assembly 1 in a direction that moves the housing 2 and the top cover assembly 1 away from each other, so as to separate the top cover assembly 1 and the housing 2.

[0144] Optionally, as shown in Figures 3 to 23, the top cover assembly 1 may include a support frame 11. A portion of the support frame 11 may be located within the receiving cavity 21. For example, a portion of the support frame 11 may be located within the receiving cavity 21 through the opening end 25 of the housing 2. The support frame 11 and the side wall 22 of the housing 2 may be interference-fitted, that is, the top cover assembly 1 and the housing 2 may be connected through the interference fit between the support frame 11 and the side wall 22 of the housing 2.

[0145] The side wall 22 of the housing 2 and the support frame 11 can be sealed to each other, making the receiving cavity 21 a sealed chamber to prevent leakage of liquid within the receiving cavity 21. The receiving box 012 may include a sealing element 4, which can be disposed between the side wall 22 of the housing 2 and the support frame 11, and located at the interference fit between the side wall 22 of the housing 2 and the support frame 11, so as to seal the side wall 22 of the housing 2 and the support frame 11 together. Furthermore, the side wall 22 of the housing 2 and the support frame 11 can achieve an interference fit through the sealing element 4. The sealing element 4 can be a sealing ring, but is not limited to this.

[0146] The first unlocking component 3 can be mounted on the support frame 11, and the first unlocking component 3 can be configured to push the housing 2 by actuating the actuator 31 and utilizing the first trigger 32. Since the first unlocking component 3 is mounted on the support frame 11, when the first trigger 32 pushes the housing 2, its reaction force can also cause the support frame 11 to move away from the housing 2, thereby making the disassembly of the top cover component 1 faster and more convenient.

[0147] As shown in Figures 6 and 11, the support frame 11 may include a mounting member 111. The mounting member 111 may face the receiving cavity 21, and the first unlocking component 3 may be disposed on the side of the mounting member 111 facing away from the receiving cavity 21. Since the first unlocking component 3 will bear a large load when pushing the housing 2, the above arrangement can provide a more stable installation position for the first unlocking component 3 using the mounting member 111, ensuring the connection strength between the first unlocking component 3 and the support frame 11, and avoiding the problem of breakage at the connection between the first unlocking component 3 and the support frame 11 due to the large load borne by the first unlocking component 3.

[0148] Optionally, as shown in Figures 4 to 13, the first trigger 32 can be rotatably mounted on the side of the mounting member 111 facing away from the receiving cavity 21. The actuator 31 can be configured to actuate the first trigger 32 to rotate via a first movement, thereby causing the first trigger 32 to push the housing 2. For example, when the actuator 31 actuates the first trigger 32 to rotate via the first movement, the first trigger 32 can push the side wall 22 located at the opening end 25. With this configuration, the housing 2 can be pushed by the rotational movement of the first trigger 32, thereby saving the force required by the user when disassembling the top cover assembly 1 and further improving the user experience.

[0149] The two ends of the first trigger 32 can be a connecting end 321 and a pushing end 322, respectively. The connecting end 321 can be rotatably connected to the mounting member 111. In one embodiment, the connecting end 321 can be rotatably connected to the side of the mounting member 111 facing away from the receiving cavity 21. With this configuration, only one end of the first trigger 32 can move in the height direction X of the housing 2 during rotation, thereby reducing the height space occupied by the first trigger 32 during rotation, and thus reducing the height of the receiving box 012.

[0150] As shown in Figures 8 and 13, the pushing end 322 can have a first position (as shown in Figure 8) and a second position (as shown in Figure 13). In the height direction X of the housing 2, the second position is closer to the side wall 22 located at the opening end 25 relative to the first position. The actuator 31 can be configured to actuate the pushing end 322 from the first position to the second position via a first movement, so that the pushing end 322 pushes the side wall 22 located at the opening end 25 to complete the disassembly of the top cover assembly 1. It should be noted that the actuator 31 can drive the connecting end 321 to rotate, causing the pushing end 322 to move from the first position to the second position.

[0151] Optionally, as shown in Figures 5 and 10, the actuator 31 may include a handle 311 and a pressing part 312. The user can actuate the entire actuator 31 by operating the handle 311. The handle 311 can be a handle, but is not limited to this. The handle 311 can also be other structural components, such as a pull ring, a handle, etc. This disclosure does not impose any special limitations on this, and the selection and setting can be made according to the actual situation.

[0152] The pressing part 312 may include a mounting base 3121 and a pressing column 3122. The mounting base 3121 may be mounted on the side of the handheld part 311 near the first trigger 32. One end of the pressing column 3122 may be mounted on the side of the mounting base 3121 away from the handheld part 311, and the other end of the pressing column 3122 may be connected to the first trigger 32.

[0153] The pressing column 3122 may have a third position and a fourth position. In the height direction X of the housing 2, the fourth position may be closer to the side wall 22 located at the opening end 25 than the third position. The actuator 31 may be configured to rotate the hand-held part 311 to move the pressing column 3122 from the third position to the fourth position, so as to push the pushing end 322 from the first position to the second position.

[0154] The pressing column 3122 can be installed on the edge of the mounting base 3121. When the handle 311 is rotated, the handle 311 can drive the mounting base 3121 and the pressing column 3122 to rotate. Since the pressing column 3122 is installed on the edge of the mounting base 3121, the pressing column 3122 can be displaced in the height direction X of the housing 2 during rotation, so that the pressing column 3122 can move from the third position to the fourth position to push the pushing end 322 from the first position to the second position.

[0155] Optionally, as shown in Figures 5 and 10, a receiving groove 323 can be provided on the side of the first trigger 32 near the handheld part 311, and the other end of the pressing column 3122 can be located in the receiving groove 323. With this configuration, when the first trigger 32 is connected to the pressing column 3122, it is no longer necessary to use the connecting piece 1321 or welding for connection. The connection between the first trigger 32 and the pressing column 3122 can be achieved directly by utilizing the cooperation between the receiving groove 323 and the pressing column 3122, thereby simplifying the connection steps between the first trigger 32 and the pressing column 3122 and improving its connection efficiency.

[0156] The receiving groove 323 and the pressing column 3122 can be interference-fitted, which can improve the stability of the fit between the pressing column 3122 and the receiving groove 323 and improve the connection strength between the first trigger 32 and the pressing column 3122.

[0157] However, it is not limited to this. The first trigger 32 and the pressing column 3122 can also be connected by means of connector 1321 or welding. The selection and setting can be made according to the actual situation, and all of this is within the protection scope of this disclosure.

[0158] As shown in Figures 6 and 11, the distance between the receiving groove 323 and the pushing end 322 in the first direction Y can be less than the distance between the receiving groove 323 and the connecting end 321, where the first direction Y can be the direction in which the pushing end 322 points to the connecting end 321. This arrangement allows the position where the actuator 31 applies a pushing force to the first trigger 32 to be close to the pushing end 322, thereby increasing the pushing force on the pushing end 322. This allows the user to complete the disassembly of the upper cover assembly 1 without applying excessive force to the actuator 31.

[0159] Optionally, as shown in Figure 14, the receiving groove 323 can be a closed groove structure. This means that the receiving groove 323 may have only one opening through which the pressing column 3122 can extend into the receiving groove 323. With this configuration, the groove wall of the receiving groove 323 can be used to limit the pressing column 3122, preventing it from falling out of the receiving groove 323.

[0160] The receiving groove 323 may include a first groove wall 3231 and a second groove wall 3232 disposed opposite to each other along the first direction Y. The first groove wall 3231 and / or the second groove wall 3232 may be configured to block the movement of the pressing column 3122 along the first direction when the pressing column 3122 is in the fourth position, thereby limiting the rotation of the handheld part 311 and preventing the handheld part 311 from rotating too much, causing inconvenience to the user.

[0161] Optionally, as shown in FIG15, the hand-held part 311 may have a third limiting part 3111. When the pressing column 3122 moves from the third position to the fourth position, the third limiting part 3111 may abut against the upper cover assembly 1 to limit the rotation of the hand-held part 311.

[0162] The first trigger 32 may include a body 324, a rotating connector 325, and a pushing block 326. The body 324 may have the aforementioned connecting end 321 and pushing end 322. The rotating connector 325 may be disposed at the connecting end 321 and may be rotatably connected to the side of the mounting member 111 facing away from the receiving cavity 21. The pushing block 326 may be disposed at the pushing end 322 and may be located on the side of the body 324 near the mounting member 111. By providing the pushing block 326, the contact area between the first trigger 32 and the side wall 22 at the opening end 25 can be increased from line contact to surface contact, thereby reducing the pressure exerted on the first trigger 32 when pushing the housing 2, reducing the probability of damage to the first trigger 32, and increasing the service life of the receiving housing 012.

[0163] The first trigger 32 may further include a connecting block 327. The connecting block 327 may be disposed on the side of the body 324 facing away from the mounting member 111. In the first direction Y, the distance between the connecting block 327 and the pushing end 322 may be less than the distance between the connecting block 327 and the connecting end 321, and the receiving groove 323 may be disposed on the side of the connecting block 327 near the handheld part 311. With this arrangement, the connecting block 327 can be connected to the pressing column 3122, thus eliminating the need to create the receiving groove 323 in the body 324. This ensures that the body 324 has high structural strength, further reducing the probability of the first trigger 32 being damaged when pushing the housing 2, and further improving the service life of the housing 012.

[0164] Optionally, there may be two first triggers 32, which can be rotatably mounted on opposite sides of the mounting member 111. The actuator 31 may include two pressing parts 312, the mounting seats 3121 of which can be respectively mounted on opposite sides of the handheld part 311, and the pressing posts 3122 of which can be respectively connected to adjacent first triggers 32. This arrangement increases the number of positions where the first unlocking component 3 applies a pushing force to the housing 2, allowing the opposite sides of the housing 2 to be subjected to force simultaneously and evenly, facilitating the separation of the top cover assembly 1 from the housing 2.

[0165] Optionally, as shown in Figures 5, 6, 10, and 11, the sidewall 22 located at the opening end 25 may be provided with a boss 23, which may protrude inward and / or outward from the rest of the sidewall 22. The inward direction can be the direction in which the sidewall 22 points towards the receiving cavity 21 in a plane parallel to the bottom wall of the housing 2, and the outward direction can be opposite to the inward direction.

[0166] The actuator 31 can be configured to actuate the first trigger 32 to rotate via a first movement, thereby causing the first trigger 32 to push the boss 23. For example, the first movement can actuate the push end 322 from a first position to a second position, so that the push end 322 contacts the boss 23 and pushes the boss 23. This configuration increases the force-bearing area between the first trigger 32 and the housing 2, making it easier for the first trigger 32 to apply a pushing force to the housing 2, and facilitating the separation of the top cover assembly 1 from the housing 2.

[0167] When the first unlocking component 3 includes two first triggers 32, the side wall 22 located at the opening end 25 can be provided with two protrusions 23. The two protrusions 23 can be located at positions corresponding to the two first triggers 32, so that the two first triggers 32 can apply a pushing force to their corresponding protrusions 23 respectively.

[0168] Optionally, as shown in Figures 2, 18, and 22, the top cover assembly 1 may include a top cover 12 and a separation assembly 14. The separation assembly 14 may be used at least for separating water vapor, and may include the support frame 11 described above. The top cover 12 may be mounted on the side of the support frame 11 away from the receiving cavity 21. The edge of the top cover 12 may contact the side wall 22 of the housing 2, for example, the edge of the top cover 12 may contact the side wall 22 located at the opening end 25.

[0169] The top cover assembly 1 may further include a second unlocking assembly 13. The second unlocking assembly 13 may include a second trigger 131 and a locking member 132. The top cover assembly 1 can be connected to the main body 011 of the cleaning device 01 via the locking member 132 to enable the installation of the receiving box 012 on the cleaning device 01. The second trigger 131 can be connected to the locking member 132, and the second trigger 131 can be configured to separate the locking member 132 from the main body 011 of the cleaning device 01 by actuating the second trigger 131, thereby enabling the disassembly of the receiving box 012.

[0170] The top cover 12 may have a side plate 121 and a top plate 122. The edge of the side plate 121 may contact the side wall 22 of the housing 2, while the top plate 122 may be located away from the housing 2 relative to the side plate 121. For example, the edge of the side plate 121 may contact the side wall 22 located at the opening end 25. The side plate 121 may be provided with a notch 123, and the top plate 122 may be provided with a first through hole 124. A second trigger 131 may be located within the notch 123 and connected to the support frame 11.

[0171] The locking member 132 may include a connector 1321 and a locking block 1322. The locking block 1322 can be connected to the second trigger member 131 through the connector 1321, and the locking block 1322 can pass through the first through hole 124 for connection with the main body 011 of the cleaning device 01. When it is necessary to remove the housing 012 from the main body 011 of the cleaning device 01, the second trigger member 131 can be pressed down to drive the connector 1321 and the locking block 1322 to move away from the main body 011 of the cleaning device 01, thereby separating the locking block 1322 from the main body 011 of the cleaning device 01, thus realizing the removal of the housing 012.

[0172] As shown in Figure 22, the second unlocking component 13 may further include a restoring element 133. The restoring element 133 may be disposed between the second trigger 131 and the support frame 11 to restore the second trigger 131 to its initial position after the second trigger 131 is actuated. The restoring element 133 may be an elastic element, such as a spring, etc., and this disclosure does not limit it.

[0173] As shown in Figure 18, a mounting post 112 may be provided on the side of the support frame 11 facing the second trigger member 131. The recovery element 133 may be sleeved on the mounting post 112 to prevent the recovery element 133 from falling off after being squeezed, thereby improving the reliability of the second unlocking assembly 13. In one embodiment, the mounting post 112 may be provided on the side of the mounting member 111 facing away from the receiving cavity 21, and the recovery element 133 may be provided between the second trigger member 131 and the side of the mounting member 111 facing away from the receiving cavity 21.

[0174] Optionally, as shown in Figure 18, the housing 2 may have a sewage inlet 24, which may be located on the side of the housing 2 away from the opening end 25. The separation assembly 14 forms a first air duct 1411, a second air duct 1412, and a third air duct 1413 within the receiving cavity 21. The inlet of the first air duct 1411 may communicate with the sewage inlet 24, and the outlet of the first air duct 1411 may be located near the top cover 12 and communicate with the inlet of the second air duct 1412. The outlet of the second air duct 1412 may be located away from the top cover 12 and communicate with the receiving cavity 21. The inlet of the third air duct 1413 may be located away from the top cover 12 and communicate with the receiving cavity 21. The outlet of the third air duct 1413 may be located near the top cover 12 and used to connect to the negative pressure device of the cleaning equipment 01, such as a fan.

[0175] The separation component 14 forms a first air duct 1411, a second air duct 1412, and a third air duct 1413 within the receiving cavity 21. Wastewater entering the receiving tank 012 through the inlet 24 passes through the first air duct 1411 and the second air duct 1412. Because the outlet of the first air duct 1411 is located on the side near the top and is connected to the inlet of the second air duct 1412, and the outlet of the second air duct 1412 is located on the side away from the top cover 12 and is connected to the receiving cavity 21, the wastewater is drawn up from the first air duct 1411 through the inlet 24 and then turns 180° through the first air duct 1411 and the second air duct 1412, causing the wastewater to move downwards and fall to the bottom of the receiving tank 012. The third air duct 1413 causes the gas to turn upward, so that the direction of movement of the sewage (the movement path indicated by the solid arrow) is opposite to the direction of movement of the gas (the movement path indicated by the dashed arrow), which greatly improves the gas-water separation effect. Therefore, it can reduce the amount of water vapor entering the negative pressure device and improve the safety and service life of the negative pressure device.

[0176] Optionally, as shown in Figures 3 and 16 to 23, the support frame 11 may include a mounting portion 113 and an air duct portion 114. The mounting portion 113 may be interference-fitted with the side wall 22 of the housing 2, and a portion of the air duct 141 may be formed on the air duct portion 114. Specifically, a second air duct 1412 may be formed on the air duct portion 114, and the air duct portion 114 may cooperate with the side wall 22 of the housing 012 to form a third air duct 1413. With this arrangement, the third air duct 1413 can be formed by utilizing other existing structures, so that the formed third air duct 1413 can have a larger air duct 141 area, thereby improving the unobstructed flow of the third air duct 1413 and further improving the air-water separation effect.

[0177] Optionally, the air duct section 114 may include an air guide pipe 115, which can form a second air duct 1412. By forming the second air duct 1412 through the air guide pipe 115, the volume occupied by the second air duct 1412 in the receiving cavity 21 is reduced, while the drainage effect of the sewage is improved.

[0178] The duct 115 may include a duct body 1151 and an elbow 1152. The outlet of the elbow 1152 is sealed to the duct body 1151, and the inlet of the elbow 1152 is connected to the outlet of the first air duct 1411. The elbow 1152 and the duct body 1151 form a second air duct 1412. The second air duct 1412 forms a first 90° turn at the elbow 1152 and a second 90° turn at the connection point between the duct body 1151 and the elbow 1152, thereby allowing the sewage entering the first air duct 1411 to achieve a 180° turn through the second air duct 1412.

[0179] The duct body 1151 and the elbow 1152 can be detachably connected by means of threaded connection, snap-fit, etc. A sealing ring can also be installed between the connection points of the duct body 1151 and the elbow 1152 to improve the sealing performance of the connection between the duct body 1151 and the elbow 1152, and prevent sewage from leaking out from the connection point or air leakage at the connection point, which would reduce the air-water separation effect. Of course, the duct body 1151 and the elbow 1152 can also be fixedly connected by means of bonding, welding, etc., and the duct body 1151 and the elbow 1152 can also be a one-piece molded structure. This disclosure does not impose any restrictions on this.

[0180] As shown in Figure 16, extensions 1153 are formed on both sides of the air duct 115. The extensions 1153 on both sides are in sealed contact with the side walls 22 of the housing 2, so that the air duct 115, the extensions 1153 on both sides, and the side walls 22 of the housing 2 form a third air duct 1413. A sealing element 4 can be provided between the extensions 1153 on both sides and the side walls 22 of the housing 2 to improve the sealing effect between the extensions 1153 and the side walls 22 of the housing 2.

[0181] Optionally, as shown in Figures 18, 19, and 23, the air duct section 114 may further include a sewage inlet pipe 142, which forms a first air duct 1411. The inlet of the sewage inlet pipe 142 is connected to the sewage inlet 24, and the inlet of the air guide pipe 115 is sealed and plugged into the outlet of the sewage inlet pipe 142. The first air duct 1411 formed by the sewage inlet pipe 142 cooperates with the second air duct 1412 of the air duct section 114 on the support frame 11, realizing a 180° turn of the sewage, allowing the sewage to move downward and fall to the bottom of the receiving tank 012. Setting the sewage inlet pipe 142 and the support frame 11 to a sealed plug-in connection makes it easy to remove the support frame 11 from the receiving tank 012 to pour the sewage in the receiving tank 012 out from the opening end 25.

[0182] The elbow 1152 of the air duct 115 and the sewage inlet pipe 142 can be connected together by plugging. By setting the elbow 1152, it is easy to adjust the plugging direction of the elbow 1152 and the sewage inlet pipe 142 so that the plugging direction of the elbow 1152 and the sewage inlet pipe 142 is along the height direction X of the box 2, thereby facilitating the removal of the support frame 11 from the box 2.

[0183] When elbow 1152 is inserted into inlet pipe 142, the outlet end of inlet pipe 142 can be located inside the inlet end of elbow 1152. Since elbow 1152 acts as the active component when it is inserted into inlet pipe 142, the larger inlet of elbow 1152 facilitates its fitting onto inlet pipe 142, thus facilitating the assembly of support frame 11.

[0184] When elbow 1152 is connected to sewage inlet pipe 142, a sealing ring can be installed between elbow 1152 and sewage inlet pipe 142 to improve the sealing performance after elbow 1152 and sewage inlet pipe 142 are connected, and to prevent sewage from leaking out from the connection point or air leakage at the connection point, which would reduce the gas-water separation effect.

[0185] Optionally, in the height direction X of the housing 2, the outlet of the second air duct 1412 and the inlet of the third air duct 1413 can be at the same height. By making the outlet of the second air duct 1412 and the inlet of the third air duct 1413 at the same height, after the sewage and gas are discharged through the outlet of the second air duct 1412, the gas can be turned 180° in time and discharged upward through the third air duct 1413, thereby improving the gas-water separation effect.

[0186] Optionally, as shown in Figure 19, the sewage inlet pipe 142 is disposed near the side wall 22 of the sewage container 012, and the outlet of the sewage inlet pipe 142 can point from the side wall 22 towards the container cavity 21. Furthermore, the outlet of the sewage inlet pipe 142 can point from the side wall 22 towards the container cavity 21 and the top cover 12. When the sewage container 012 is full, the accumulated sewage in the container 2 needs to be poured out through the opening end 25. Since the sewage inlet pipe 142 is fixedly connected to the sewage inlet 24 of the container 2, when water is poured out from the opening end 25 of the container 2, there is a backflow of sewage through the sewage inlet pipe 142, causing sewage to flow out from the sewage inlet 24 of the container 2, easily soiling the user's shoes and clothing, seriously affecting the user experience. This disclosure, through the above-mentioned arrangement, ensures that the outlet of the sewage inlet pipe 142 is always kept above the liquid level, preventing sewage from flowing out from the sewage inlet 24 and improving the user experience.

[0187] The outlet of the sewage inlet pipe 142 has a first included angle α with respect to the height direction of the box. The first included angle α can be greater than 0° and less than 180°, so that the outlet of the sewage inlet pipe 142 can always be kept above the liquid surface, while not affecting the unobstructed flow of the air duct 141 formed after connecting with the elbow 1152. The first included angle α can be, for example, 10°, 20°, 30°, 40°, 50°, 60°, 70°, 80°, 90°, 100°, 110°, 120°, 130°, 140°, 150°, 160°, 170°, etc., which will not be listed here in this disclosure.

[0188] Preferably, the first included angle α can be greater than 0° and less than or equal to 90°, so as to further ensure the unobstructed flow of the air duct 141 formed after the outlet of the sewage pipe 142 is connected to the elbow 1152.

[0189] As shown in Figures 18, 19, and 22, the inlet pipe 142 and the housing 2 can be integrally formed to improve the structural strength of the inlet pipe 142, thereby improving the sealing performance when the inlet pipe 142 and the elbow 1152 are connected. Of course, the inlet pipe 142 and the housing 2 can also be separate structures, for example, connected by bonding, welding, threaded connection, or snap-fit, and this disclosure does not impose any limitations on this. When the inlet pipe 142 and the housing 2 are integrally formed, at least a portion of the inlet pipe 142 can be the second sidewall 22 of the housing 2.

[0190] Optionally, as shown in Figures 3, 16 to 18, and 22, the separation assembly 14 may further include a filter element 143. The filter element 143 may be disposed in the receiving cavity 21 and divide the receiving cavity 21 into a first receiving space 211 and a second receiving space 212 along the height direction X of the housing 2. The filter element 143 may be provided with a clearance notch 123, and the sewage inlet pipe 142 may be located in the clearance notch 123. By setting the filter element 143, solid impurities in the sewage can be filtered out, thereby preventing impurities from clogging the sewage outlet in the user's usage scenario when sewage is poured out. The clearance notch 123 provided on the filter element 143 can cooperate with the sewage inlet pipe 142 to prevent impurities from entering the second receiving cavity 21.

[0191] The filter element 143 can be connected to the support frame 11, and the filter element 143 can be removed at the same time as the support frame 11 is removed so that the filtered impurities can be poured out.

[0192] As shown in Figure 22, the filter element 143 may be provided with a connecting rod 1433, which can connect the filter element 143 to the support frame 11. The connecting rod 1433 and the support frame 11 can be detachably connected, for example, by means of threaded connection, snap-fit, or other connection methods. Of course, the connecting rod 1433 and the support frame 11 can also be fixedly connected by means of bonding, welding, or other connection methods, and this disclosure does not impose any limitations on this.

[0193] Optionally, as shown in Figures 16 to 18, the filter element 143 may include a first filter section 1431 corresponding to the second air duct 1412 and a second filter section 1432 corresponding to the third air duct 1413. In the height direction X of the housing 2, the first filter section 1431 is farther away from the top cover 12 relative to the second filter section 1432, so that the filter element 143 can accommodate more solid debris.

[0194] Optionally, the first filter section 1431 can be flat, meaning that the side of the first filter section 1431 closest to the inlet pipe 142 is unobstructed, forming a semi-open structure, making it easier for debris accumulated on the filter element 143 to be poured out. Side baffles can be provided on both sides of the first filter section 1431 to cooperate with the flat first filter section 1431 to form a shovel-shaped structure, better accommodating accumulated debris. Of course, the first filter section 1431 can also be cylindrical, and this disclosure does not limit this.

[0195] Optionally, as shown in Figures 17, 18, and 22, the separation assembly 14 further includes a first filter 144, which may be disposed in the third air duct 1413. By providing the first filter 144 in the third air duct 1413, the gas passing through the third air duct 1413 can be filtered, preventing impurities in the gas from entering the negative pressure device from the outlet of the third air duct 1413 and damaging the negative pressure device.

[0196] Optionally, the first filter screen 144 and the side wall 22 of the housing 2 may have a first acute angle β. The first acute angle β may be greater than or equal to 20° and less than or equal to 45°. For example, the first acute angle β may be 20°, 25°, 30°, 35°, 40°, 45°, etc., which will not be listed here. That is, the first filter screen 144 is inclined relative to the side wall 22 of the housing 2, thereby increasing the filtration area of ​​the first filter screen 144 and improving its filtration capacity.

[0197] The first filter screen 144 can be detachably connected to the support frame 11. For example, the first filter screen 144 can be detachably connected to the support frame 11 by means of threaded parts or by means of snap-fit, so as to facilitate the installation, removal and maintenance of the first filter screen 144.

[0198] Optionally, as shown in Figures 2 to 16 and Figure 18, the upper cover 12 may have a second through-hole, which can be the outlet of the third air duct 1413. The separation assembly 14 also includes a second filter 145, which can be disposed within the second through-hole to cooperate with the first filter 144 to form a two-stage filtration. The second filter 145 may be inclined within the second through-hole to increase its filtration area and improve its filtration capacity.

[0199] The mesh size of the second filter 145 can be smaller than that of the first filter 144 to achieve better filtration and further filter out minute impurities in the gas. The second filter 145 can be a HEPA (High Efficiency Particulate Air Filter) filter, which increases its lifespan, but it is not limited to this type. Other types of filters can also be used, and selection and configuration can be made according to specific circumstances.

[0200] The second filter 145 can be detachably connected to the top cover 12. For example, the second filter 145 can be detachably connected to the top cover 12 by snap-fit ​​or by threaded connection, so as to facilitate the installation, removal and maintenance of the second filter 145.

[0201] Optionally, as shown in Figures 16 to 22, the upper cover assembly 1 may further include a liquid level monitoring assembly 15. The liquid level monitoring assembly 15 may include a first monitoring point 151 and a second monitoring point 152 located in the receiving cavity 21. In the height direction X of the housing 2, the second monitoring point 152 may be located above the first monitoring point 151.

[0202] When the cleaning device 01 is in its normal operating angle, the angle between the container 012 and the ground is approximately 45°. When the cleaning device 01 is in its horizontal operating angle, the angle between the container 012 and the ground is approximately 0°. When the cleaning device 01 switches operating states, the angle of the container 012 changes, which in turn causes changes in the liquid level within the container 012. If the liquid level in the container 012 at different angles cannot be accurately monitored, the cleaning device 01 may malfunction, severely impacting the user experience.

[0203] In this embodiment, as shown in Figure 20, the liquid level can be monitored at the lower first monitoring point 151 when the angle between the container 012 and the ground is approximately 45°. When the liquid level reaches the height of the first monitoring point 151, the liquid continuously submerges the first monitoring point 151, indicating that the container 012 is full. At this time, the higher second monitoring point 152 is not submerged by sewage. As shown in Figure 21, the liquid level can be monitored at the upper second monitoring point 152 when the angle between the container 012 and the ground is approximately 0°. When the liquid level reaches the height of the second monitoring point 152, the sewage continuously submerges the second monitoring point 152, indicating that the container 012 is full. Therefore, this embodiment achieves accurate judgment of whether the sewage tank 012 is full in normal and lying states by using the first monitoring point 151 and the second monitoring point 152 at different heights. This avoids the phenomenon that the sewage tank 012 cannot be detected in time after it is full, and also avoids excessive water entering the negative pressure device due to failure to stop the machine in time after the water is full.

[0204] Optionally, the liquid level monitoring assembly 15 may include a first monitoring rod 153 and a second monitoring rod 154, which may be located in the receiving cavity 21 and extend along the height direction X of the housing 2. A first monitoring point 151 and a second monitoring point 152 are formed on both the first monitoring rod 153 and the second monitoring rod 154, with one of the first monitoring rod 153 being a positive electrode and the other a negative electrode.

[0205] When the container tank 012 is at its normal operating angle and the liquid level reaches the height of the first monitoring point 151, water will continuously submerge the first monitoring point 151 on the first monitoring rod 153 and the second monitoring rod 154. The first monitoring point 151 on the positive and negative monitoring rods forms a circuit through water conduction, which indicates that the container tank 012 is full of water. At this time, the higher second monitoring point 152 on the first monitoring rod 153 and the second monitoring rod 154 is not submerged by sewage. When the sewage container tank 012 is at its horizontal operating angle and the liquid level reaches the height of the second monitoring point 152, water will continuously submerge the first monitoring point 151 and the second monitoring point 152. The first monitoring point 151 and the second monitoring point 152 on the positive and negative monitoring rods simultaneously form two parallel circuits through water conduction, which indicates that the container tank 012 is full of water.

[0206] A controller can be installed on the container 012 or other components of the cleaning equipment 01 to determine the electrical signal between the first monitoring rod 153 and the second monitoring rod 154. For example, when the first monitoring point 151 on the positive and negative monitoring rods forms a circuit through water conduction, the liquid level can be determined by setting a fixed voltage and judging the current magnitude; or, the liquid level can be determined by judging the resistance between the positive and negative monitoring rods. When the first monitoring point 151 and the second monitoring point 152 on the positive and negative monitoring rods simultaneously form two parallel circuits through water conduction, the liquid level in the container 012 when it is in a horizontal position can be determined by judging the current magnitude; or, the liquid level can be determined by judging the resistance between the positive and negative monitoring rods.

[0207] During the movement of the container 012, the water inside 012 sloshes, causing the water level to rise and briefly submerge the monitoring point, potentially leading to false level alarms. To address this, when the monitoring points on the positive and negative monitoring rods are connected, the controller detects the change in electrical signal. A preset delay time can be set in the controller. If the duration of the signal change exceeds the preset delay time, the liquid level is considered to have reached the monitoring point; if the duration is less than or equal to the preset delay time, the liquid level is considered not to have reached the monitoring point. This prevents false level alarms and improves the accuracy of liquid level monitoring.

[0208] Optionally, the preset delay time can be greater than or equal to 3 seconds, such as 3 seconds, 4 seconds, 5 seconds, etc., and this disclosure does not impose any limitation on it. By controlling the preset delay time, that is, the conduction time between monitoring points, the water volume when the full water alarm occurs can be further controlled, and the capacity of the alarm for normal full water and lying flat full water can be adjusted.

[0209] Optionally, in the height direction X of the housing 2, the heights of the first monitoring points 151 on the first monitoring rod 153 and the second monitoring rod 154 can be the same, allowing water to simultaneously submerge both the first monitoring points 151 on the first monitoring rod 153 and the second monitoring rod 154; or, the heights of the second monitoring points 152 on the first monitoring rod 153 and the second monitoring rod 154 can be the same, allowing water to simultaneously submerge both the first monitoring points 151 on the first monitoring rod 153 and the second monitoring rod 154; or, the heights of the first monitoring points 151 on the first monitoring rod 153 and the second monitoring rod 154 can be the same, and the heights of the second monitoring points 152 on the first monitoring rod 153 and the second monitoring rod 154 can also be the same, allowing water to simultaneously submerge both the first monitoring points 151 on the first monitoring rod 153 and the second monitoring points 152 on the second monitoring rod 154.

[0210] However, this is not limited to this. The height of the first monitoring point 151 on the first monitoring rod 153 and the second monitoring rod 154 may also have a height difference, and the height of the second monitoring point 152 on the first monitoring rod 153 and the second monitoring rod 154 may also have a height difference. This disclosure does not limit this.

[0211] Optionally, the first monitoring point 151 on the first monitoring rod 153 can be located at the end of the first monitoring rod 153; or, the first monitoring point 151 on the second monitoring rod 154 can be located at the end of the second monitoring rod 154; or, the first monitoring point 151 on the first monitoring rod 153 can be located at the end of the first monitoring rod 153, and the first monitoring point 151 on the second monitoring rod 154 can also be located at the end of the second monitoring rod 154. This arrangement shortens the length of the monitoring rod, ensures the reliability of the monitoring rod's operation, and avoids the monitoring rod occupying excessive space within the housing 2.

[0212] However, this is not a limitation. The first monitoring point 151 on the first monitoring rod 153 may not be located at the end of the first monitoring rod 153, and the first monitoring point 151 on the second monitoring rod 154 may not be located at the end of the second monitoring rod 154. This disclosure does not impose any restrictions on this.

[0213] Optionally, both the first monitoring rod 153 and the second monitoring rod 154 may include a conductive post and an insulating layer covering the conductive post, with the conductive post exposed above the insulating layer at the first monitoring point 151 and the second monitoring point 152. The insulating layer may be a plastic material layer formed on the surface of the metal conductive post through an injection molding process, thereby improving the corrosion resistance and stability of the monitoring rod, but is not limited to this.

[0214] Optionally, the support frame 11 may be provided with multiple connection holes, and the first monitoring rod 153 and the second monitoring rod 154 may be inserted into the corresponding connection holes respectively, so as to facilitate the assembly of the first monitoring rod 153 and the second monitoring rod 154.

[0215] As shown in Figure 22, the liquid level monitoring component 15 may further include a first contact electrode 155 and a second contact electrode 156, which can be mounted on the support frame 11. The first contact electrode 155 can be connected to the first monitoring rod 153, and the second contact electrode 156 can be connected to the second monitoring rod 154. By setting the first contact electrode 155 and the second contact electrode 156, the first monitoring rod 153 can be connected to the controller through the first contact electrode 155, and the second monitoring rod 154 can be connected to the controller through the second contact electrode 156, thereby enabling the controller to monitor changes in electrical signals.

[0216] The first contact electrode 155 and the first monitoring rod 153 can be an integral structure, and the second contact electrode 156 and the second monitoring rod 154 can be an integral structure. The first contact electrode 155 and the second contact electrode 156 can be fixedly assembled to the support frame 11 by snap-fit. However, this is not limited to this. The first contact electrode 155 and the first monitoring rod 153 can also be separate structures, and the second contact electrode 156 and the second monitoring rod 154 can also be separate structures. The contact electrodes and the monitoring rods can be connected by plugging, abutting, or other means. This disclosure does not impose any restrictions on this.

[0217] Optionally, the first contact electrode 155 and the second contact electrode 156 can be mounted on the mounting member 111 and can pass through the mounting member 111 so that the first contact electrode 155 and the second contact electrode 156 can be connected to the controller.

[0218] Optionally, as shown in Figures 3 and 22, the top cover assembly 1 may further include an odor-blocking component 16. The odor-blocking component 16 may be installed on the side of the first filter section 1431 opposite to the top cover 12 to block odorous gases in the second receiving cavity 21, preventing odorous gases from leaking into the atmosphere and affecting the user's experience.

[0222] When the user does not grasp the lifting plate 51, the lifting plate 51 can be in its initial position via the elastic structural member 52. In its initial position, the lifting plate 51 is substantially flush with the outer wall of the housing 2, preventing the protruding gripper from easily catching foreign objects and enhancing the aesthetic appearance of the housing 012. In this embodiment, the side wall 22 of the housing 2 may have a recessed portion, and the lifting assembly 5 may be located within this recessed portion, so that when the lifting plate 51 is in its initial position, it can be substantially flush with the outer wall of the housing 2, but this is not a limitation.

[0223] When the user lifts the container 012 using the lifting plate 51, the lifting plate 51 can rotate to the side away from the container cavity 21 to increase the space for the user to lift and facilitate the user to apply force to the lifting plate 51. When the user releases the lifting plate 51, the elastic structure 52 can use its internal elastic restoring force to push the lifting plate 51 back to its initial position.

[0224] Optionally, as shown in Figures 18 and 23, the elastic structural member 52 can be connected to the side wall 22 of the housing 2. This arrangement can improve the installation stability of the elastic structural member 52 and prevent the elastic structural member 52 from detaching from the lifting plate 51 and the side wall 22 of the housing 2 after deformation.
