[0023] In order to make the purpose, technical solution and advantages of the present application more clearly understood, the present application is further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present application and are not used to separate the present application.

[0024] The present application provides a sewage tank and a cleaning device to solve the problem in the related art that when the cleaning device absorbs sewage, some solid garbage will be sucked into the sewage tank together with the sewage, and the solid garbage and sewage will mix and ferment in the sewage tank, which is likely to produce a strong odor.

[0025] In a first aspect, the present application provides a sewage tank 20, such as Figures 1 to 3 As shown, the sewage tank 20 includes a tank body 30 , a partition 51 and a cover body 40 .

[0026] The box body 30 has a sewage chamber 31, a sewage inlet 331a and an opening 32, and the sewage inlet 331a and the opening 32 are both connected to the sewage chamber 31; it should be noted that when the sewage tank 20 is applied to the cleaning equipment, the fan 60 (such as Figure 8 ) The airflow generated by the sewage tank 20 absorbs the dirt, and the absorbed dirt can enter the sewage chamber 31 through the sewage inlet 331a for storage; illustratively, the material of the box body 30 can be but is not limited to plastic or metal. illustratively, the material of the box body 30 can be plastic to reduce the weight of the sewage tank 20, so as to facilitate the user to clean the sewage tank 20.

[0027] The partition 51 is located in the sewage chamber 31 and connected to the box body 30. The partition 51 divides the sewage chamber 31 into a first chamber 311 and a second chamber 312, and the sewage inlet 331a is connected to the first chamber 311. Exemplarily, the material of the partition 51 can be, but is not limited to, plastic or metal. Exemplarily, the material of the partition 51 can be plastic to reduce the weight of the sewage tank 20, so that it is convenient for users to clean the sewage tank 20. Among them, the partition 51 and the box body 30 can be integrally formed, and the partition 51 and the box body 30 can also be formed separately and spliced ​​by gluing, welding, screw connection or riveting.

[0028] The cover 40 covers the opening 32, and has a filter hole 441, an air outlet 432a and a first liquid discharge port 411 connected to the filter hole 441. The filter hole 441 is connected to the first cavity 311, and the first liquid discharge port 411 is connected to the second cavity 312. The filter hole 441 can filter the dirt to separate the sewage from the solid garbage in the dirt. The filter hole 441 can be circular, square or other shapes. The size of the filter hole 441 can be selected according to actual needs, and this application does not make specific restrictions.

[0029] It should be noted that when the sewage tank 20 is used in a cleaning device, Figure 1 As shown, Figure 1The direction indicated by the dashed arrow is the direction of air flow. The airflow generated by the fan 60 passes through the sewage inlet 331a, the first cavity 311, the filter hole 441 and the air outlet 432a in sequence. After the dirt sucked by the cleaning equipment enters the first cavity 311 through the sewage inlet 331a, the airflow drives the sewage in the sewage to pass through the filter hole 441 and enter the cover body 40, while the solid garbage in the sewage is intercepted by the filter hole 441 and retained in the first cavity 311. The sewage entering the cover body 40 can be discharged to the second cavity 312 through the first drain port 411 for storage, and the airflow will pass through the air outlet 432a and enter the fan 60.

[0030] It can be understood that in the present application, sewage and solid waste in the waste can be stored in the first cavity 311 and the second cavity 312 respectively, so that sewage and solid waste can be stored separately, which can prevent the solid waste from mixing and fermenting with sewage to produce a strong odor; in addition, it can prevent the volume of solid waste from expanding after the solid waste is mixed with sewage, and the volume of solid waste can be reduced, so that the first cavity 311 can store more solid waste.

[0031] Continue to see Figure 1 and Figure 3 As shown, in one embodiment of the present application, as Figure 8 As shown, the partition 51 can abut against the cover 40 to reduce or even eliminate the gap between the partition 51 and the cover 40 to prevent sewage in the second cavity 312 from entering the first cavity 311 through the gap between the partition 51 and the cover 40 .

[0032] In one embodiment of the present application, Figure 1 and Figure 2 As shown, the sewage tank 20 further includes a first sealing member 451, which is disposed on the cover 40 and abuts against the inner peripheral wall of the first cavity 311 to improve the sealing performance between the cover 40 and the inner peripheral wall of the first cavity 311, and prevent the sewage in the second cavity 312 from entering the first cavity 311 through the gap between the cover 40 and the inner peripheral wall of the first cavity 311. The first sealing member 451 may be made of metal, rubber, silicone or plastic; illustratively, the first sealing member 451 may be disposed around the circumference of the cover 40, that is, the first sealing member 451 is a sealing ring to further improve the sealing performance between the cover 40 and the inner peripheral wall of the first cavity 311.

[0033] Furthermore, a first sealing groove 412 is provided on the cover body 40 , and the first sealing member 451 is provided in the first sealing groove 412 to reduce the overall volume of the cover body 40 and the gap between the cover body 40 and the inner peripheral wall of the first cavity 311 .

[0034] Continue to see Figures 1 to 3As shown, in one embodiment of the present application, the sewage tank 20 also includes an anti-blocking plate 52, which is located in the first cavity 311 and connected to the tank body 30. The anti-blocking plate 52 divides the first cavity 311 into a solid garbage cavity 311a and an isolation cavity 311b connected to the solid garbage cavity 311a. The sewage inlet 331a is arranged in the area where the solid garbage cavity 311a is located, and the filter hole 441 is arranged in the area where the isolation cavity 311b is located. It can be understood that after the dirt sucked in through the sewage inlet 331a enters the solid garbage chamber 311a, the solid garbage in the dirt will be stored in the solid garbage chamber 311a, and the sewage in the dirt will enter the cover body 40 through the filter hole 441. When the sewage enters the cover body 40 through the filter hole 441, some of the sewage may flow back under the action of gravity and flow out of the cover body 40 through the filter hole 441. In the embodiment of the present application, by arranging the filter hole 441 in the area where the isolation chamber 311b is located, the sewage flowing out of the cover body 40 through the filter hole 441 will flow into the isolation chamber 311b for storage, which can prevent the refluxed sewage from mixing with the solid garbage in the solid garbage chamber 311a, and can also prevent the solid garbage in the solid garbage chamber 311a from contacting the filter hole 441 and causing the filter hole 441 to be blocked.

[0035] For example, the material of the anti-blocking plate 52 can be, but is not limited to, plastic or metal. For example, the material of the anti-blocking plate 52 can be plastic to reduce the weight of the sewage tank 20, so that it is convenient for the user to clean the sewage tank 20. The anti-blocking plate 52 and the box body 30 can be integrally formed, or the anti-blocking plate 52 and the box body 30 can be formed separately and then spliced ​​by gluing, welding, screw connection or riveting.

[0036] Specifically, the cover body 40 may include a filter portion 44 extending into the isolation chamber 311b, and a plurality of filter holes 441 are provided on the filter portion 44, and the height of at least some of the filter holes 441 is lower than the height of the anti-blocking plate 52, and the height of only some of the filter holes 441 may be lower than the height of the anti-blocking plate 52, or the height of all the filter holes 441 may be lower than the height of the anti-blocking plate 52, so that at least some of the filter holes 441 can extend into the sewage in the isolation chamber 311b, so that the filter holes 441 can absorb the sewage in the isolation chamber 311b, and prevent the sewage in the isolation chamber 311b from overflowing the anti-blocking plate 52 and entering the solid garbage chamber 311a. The number of filter holes 441 may be 2, 3 or more, which are not listed here one by one. Alternatively, only one filter hole 441 may be provided.

[0037] For example, filter holes 441 may be provided on both the circumference and the bottom of the filter part 44, so that the airflow carrying sewage can enter the filter part 44 from all directions of the filter part 44; of course, filter holes 441 may also be provided only on the circumference or the bottom of the filter part 44. When filter holes 441 are provided on the circumference of the filter part 44, filter holes 441 may be provided on one side, two sides or more sides of the filter part 44.

[0038] Continue to see Figure 1 and Figure 3 As shown, the sewage tank 20 also includes a sewage inlet pipe 33, which is located in the first cavity 311 and connected to the box body 30, and the sewage inlet pipe 33 has a sewage inlet channel 331, and the first end of the sewage inlet channel 331 is a sewage inlet port 331a, and the second end of the sewage inlet channel 331 is a sewage outlet port 331b extending into the first cavity 311, and the sewage outlet port 331b is spaced apart from the cover body 40. It can be understood that the dirt enters the first cavity 311 after passing through the dirt inlet 331a and the dirt outlet 331b in sequence, and the dirt outlet 331b has a certain height, which can prevent the dirt in the first cavity 311 from being discharged from the first cavity 311 through the dirt outlet 331b, and there is a sufficient height difference between the dirt outlet 331b and the bottom wall of the first cavity 311, so that when the dirt is discharged from the dirt outlet 331b, the solid garbage in the dirt can fall into the first cavity 311 under the action of weight, and the sewage in the dirt can enter the cover body 40 through the filter hole 441 driven by the airflow.

[0039] Furthermore, the sewage inlet pipe 33 is connected to the bottom wall of the first cavity 311 and extends from the bottom wall of the first cavity 311 toward the direction of the opening 32 to further increase the height difference between the sewage outlet 331b and the bottom wall of the first cavity 311, so that there is a sufficient height difference between the sewage outlet 331b and the bottom wall of the first cavity 311.

[0040] Specifically, the sewage inlet pipe 33 is located in the solid waste chamber 311a, so that the solid waste in the sewage can fall into the solid waste chamber 311a under the action of weight.

[0041] Furthermore, the sewage outlet 331b may be oriented toward the filter portion 44, for example Figure 1 In the figure, the filter part 44 is located on the left side of the sewage outlet 331b, and the sewage outlet 331b is set to the left, which can reduce the path length of the airflow from the sewage outlet 331b to the filter hole 441, so that the sewage carried in the airflow can smoothly enter the filter hole 441. In other embodiments, the sewage outlet 331b can also be set forward or backward.

[0042] In one embodiment of the present application, the height of the top of the anti-blocking plate 52 may be lower than the height of the sewage outlet 331b to prevent the anti-blocking plate 52 from blocking the airflow discharged from the sewage outlet 331b from entering the filter hole 441. In other embodiments, the height of the top of the anti-blocking plate 52 may also be higher than the height of the sewage outlet 331b, or flush with the height of the sewage outlet 331b.

[0043] Furthermore, when the sewage tank 20 is applied to a cleaning device, and the cleaning device is in Figure 8 In the working posture shown, the bottom wall of the sewage chamber 31 is inclined downward from the isolation chamber 311b to the second chamber 312, so that the bottom of the second chamber 312 is at a lower position, while the bottoms of the solid garbage chamber 311a and the isolation chamber 311b are at a higher position, which can prevent the sewage in the second chamber 312 from entering the solid garbage chamber 311a due to shaking, and can prevent the solid garbage in the solid garbage chamber 311a from entering the isolation chamber 311b due to shaking.

[0044] In one embodiment of the present application, the cover body 40 is detachably connected to the box body 30. When the sewage chamber 31 needs to be cleaned, the cover body 40 is separated from the box body 30, and the sewage chamber 31 can be flushed through the opening 32, so that the cleaning of the sewage chamber 31 is more convenient. The detachable connection method between the cover body 40 and the box body 30 includes but is not limited to snap-on, threaded connection or interference fit.

[0045] like Figure 1 , Figure 4 and Figure 5 As shown, in some embodiments of the present application, the cover body 40 includes a first frame 41 and a second frame 42; the first frame 41 has a first drainage port 411; the second frame 42 is connected to the first frame 41 and forms a first slow flow chamber 46, the inlet of the first slow flow chamber 46 is connected to the filter hole 441, and the first drainage port 411 is arranged near the outlet 461 of the first slow flow chamber 46.

[0046] Among them, in the flow path of the airflow, the first slow flow cavity 46 is located downstream of the filter hole 441. It should be noted that, Figure 1 As shown, the airflow generated by the fan 60 passes through the filter hole 441, the inlet of the first slow flow chamber 46, the outlet 461 of the first slow flow chamber 46 and the air outlet 432a in sequence. By setting the first slow flow chamber 46, the airflow has a sufficiently long flow path in the process of flowing from the filter hole 441 to the air outlet 432a, so that most of the sewage carried in the airflow can be separated from the gas under the action of gravity, so as to fully achieve the purpose of water-gas separation, and can prevent the airflow entering the fan 60 from still carrying a lot of sewage, and the separated sewage can be discharged into the second cavity 312 through the first drain port 411.

[0047] Specifically, the filter part 44 is connected to the bottom of the first frame 41 and the first frame 41. The filter part 44 and the first frame 41 can be integrally formed, or the filter part 44 and the first frame 41 can be formed separately and then spliced ​​by gluing, welding, screwing or riveting.

[0048] In one embodiment of the present application, the cover body 40 has a first air vent 471, a first deflection channel 472 and a second deflection channel 473. The outlet 461 of the first slow flow chamber 46 is connected to the first deflection channel 472 through the first air vent 471, the first deflection channel 472 is connected to the second deflection channel 473, the first deflection channel 472 is located outside the second deflection channel 473, and the first deflection channel 472 is arranged around the second deflection channel 473, and the second deflection channel 473 is connected to the air outlet 432a.

[0049] The cover 40 further includes a third frame 43, which is connected to the second frame 42 to form a first baffle channel 472 and a second baffle channel 473. The first vent 471 is disposed on the second frame 42 or the third frame 43, and the air outlet 432a is disposed on the third frame 43. Figure 1 As shown, the air flow passes through the filter hole 441, the inlet of the first slow flow chamber 46, the outlet 461 of the first slow flow chamber 46, the first vent 471, the first deflection channel 472, the second deflection channel 473 and the air outlet 432a in sequence. By setting the first deflection channel 472 and the second deflection channel 473, the air flow has a longer flow path in the process of flowing from the filter hole 441 to the air outlet 432a, so as to fully achieve the purpose of water vapor separation.

[0050] In one embodiment of the present application, the first vent 471 is disposed on a side of the cover 40 away from the outlet 461 of the first slow flow chamber 46, so that the airflow flowing out of the outlet 461 of the first slow flow chamber 46 needs to go around the circumference of the cover 40 to the first vent 471, which can further increase the path length of the airflow during the flow process to achieve a better water vapor separation effect. Figure 4 From the perspective shown, the outlet 461 of the first slow flow cavity 46 is located on the right side of the cover body 40, and the first vent 471 is located on the left side of the cover body 40. After the airflow flows out of the outlet 461 of the first slow flow cavity 46, it needs to flow leftward along the circumference of the cover body 40 to the first vent 471. It should also be noted that in other embodiments, the first vent 471 can also be set on the front side or the rear side of the cover body 40.

[0051] Specifically, the second frame 42 includes a first extension portion 421 and a second extension portion 422 spaced apart from the first extension portion 421, the first extension portion 421 is located outside the second extension portion 422 and is arranged around the second extension portion 422; the third frame 43 includes a third extension portion 431 and a fourth extension portion 432 spaced apart from the third extension portion 431, the third extension portion 431 is located outside the fourth extension portion 432 and is arranged around the fourth extension portion 432, and the air outlet 432a is arranged on the fourth extension portion 432.

[0052] Among them, the first extension portion 421 is connected to the third extension portion 431, and the first deflection channel 472 is formed between the second extension portion 422 and the first extension portion 421 and the third extension portion 431; the second extension portion 422 extends to between the third extension portion 431 and the fourth extension portion 432, and the second deflection channel 473 is formed between the second extension portion 422 and the fourth extension portion 432.

[0053] It is understandable that when the airflow flows through the first baffle channel 472 to the second baffle channel 473, the airflow needs to change direction several times during the flow process to achieve the purpose of water vapor separation through baffle separation. The principle of baffle separation is: due to the different specific gravities of gas and liquid, when liquid and gas are mixed and flow together, if there is an obstacle, the gas will be baffled and go away, while the liquid will continue to have a forward speed due to inertia. The forward liquid will be separated from the gas under the action of gravity, thereby achieving water vapor separation. Specifically in this embodiment, refer to Figure 4 From the perspective shown, the airflow in the first baffle channel 472 needs to flow upward first, then flow downward to the second baffle channel 473, and then flow to the air outlet 432a. It should also be noted that when producing the cover body 40, the second frame 42 can be connected to the first frame 41 or the third frame 43, and then the third frame 43 can be assembled with the first frame 41, so that the assembly of the water-gas separator is more convenient.

[0054] It should also be noted that the first extension portion 421 and the second extension portion 422 can be integrally formed, or the first extension portion 421 and the second extension portion 422 can be formed separately and then spliced ​​by gluing, welding, screwing, or riveting. The third extension portion 431 and the fourth extension portion 432 can be integrally formed, or the third extension portion 431 and the fourth extension portion 432 can be formed separately and then spliced ​​by gluing, welding, screwing, or riveting.

[0055] In one embodiment of the present application, the air outlet 432a may be located at the bottom of the third extension portion 431, so that when the airflow in the second deflection channel 473 flows to the air outlet 432a, it needs to change direction, so as to increase the length of the flow path and the number of changes in direction during the flow of the airflow, so as to achieve a better water vapor separation effect. Figure 4 From the perspective shown, the airflow in the second deflection channel 473 needs to flow downward first, and then flow upward to the air outlet 432a.

[0056] Continue to see Figure 1 , Figure 4 and Figure 5 As shown, in some embodiments of the present application, a second drain port 423 and a third drain port 424 are provided on the second frame 42, the second drain port 423 is connected to the first baffle channel 472, and the third drain port 424 is connected to the second baffle channel 473, so that the sewage in the first baffle channel 472 can be discharged through the second drain port 423, and the sewage in the second baffle channel 473 can be discharged through the third drain port 424.

[0057] Among them, the cover body 40 also includes a first opening and closing structure 48, which is movably connected to the second frame 42, and is used to close the second drainage port 423 and the third drainage port 424. The first opening and closing structure 48 can open the second drainage port 423 and the third drainage port 424 under the action of liquid to allow the liquid to flow to the first frame 41. When the sewage tank 20 is in use, the second drain port 423 and the third drain port 424 can be closed by the first opening and closing structure 48 to prevent the airflow outside the cover body 40 from entering the first baffle channel 472 and the second baffle channel 473 respectively through the second drain port 423 and the third drain port 424, that is, to ensure that the airflow basically passes through the first vent 471, the first baffle channel 472 and the second baffle channel 473 in sequence, to ensure that the airflow has a longer flow path; when drainage is required, the second drain port 423 and the third drain port 424 can be opened, so that the sewage in the first baffle channel 472 and the second baffle channel 473 can be discharged to the first frame 41, and then discharged through the first drain port 411 on the first frame 41.

[0058] Specifically, the second drain port 423 and the third drain port 424 may be disposed at the bottom of the second frame 42 , so that the sewage in the first baffle channel 472 and the second baffle channel 473 can be discharged through the second drain port 423 and the third drain port 424 , respectively.

[0059] In some embodiments of the present application, the cover body 40 is further provided with a fourth drain port 413, which is connected to the second cavity 312 and is located upstream of the first drain port 411. When there is too much sewage and the first drain port 411 cannot discharge the sewage in time, the sewage can spread to the fourth drain port 413 and then be discharged into the second cavity 312 through the fourth drain port 413, so as to ensure that the sewage in the cover body 40 can be discharged in time.

[0060] Specifically, the sewage tank 20 further includes a second opening and closing structure 49, which is movably connected to the cover body 40, and is used to close the first drainage port 411. The second opening and closing structure 49 can open the first drainage port 411 under the action of liquid, so that the liquid flows into the second cavity 312. When the sewage tank 20 is used, the first drainage port 411 can be closed by the first opening and closing structure 48 to prevent the airflow outside the cover body 40 from entering the first slow flow cavity 46 through the first drainage port 411, that is, to ensure that the airflow basically enters the first slow flow cavity 46 through the filter hole 441, and to ensure that the airflow has a longer flow path; when there is too much sewage on the first frame 41, the second opening and closing structure 49 can open the first drainage port 411 under the pressure of the sewage, so that the liquid flows into the second cavity 312 in time.

[0061] Continue to see Figure 1 , Figure 4 and Figure 5 As shown, in one embodiment of the present application, the first opening and closing structure 48 is arranged on the outside of the first deflection channel 472 and the second deflection channel 473, and the first opening and closing structure 48 has a first connection end 481 and a first free end 482 arranged opposite to the first connection end 481, the first connection end 481 is connected to the second frame 42, and the first free end 482 is used to swing relative to the first connection end 481 in a direction away from the second frame 42 under the action of liquid. It should be noted that when the sewage tank 20 is in use, the first free end 482 naturally fits with the second frame 42 to close the second drain port 423 and the third drain port 424. When the fan 60 is started, the first free end 482 is in closer contact with the second frame 42 under the suction of the airflow generated by the fan 60, thereby ensuring that the second drain port 423 and the third drain port 424 are in a closed state; when the fan 60 stops working or the first deflection channel 472 and the second deflection channel 473 are flushed, the first free end 482 can swing relative to the first connection end 481 in a direction away from the second frame 42 under the action of the gravity and impact force of the liquid to open the second drain port 423 and the third drain port 424.

[0062] Specifically, the first opening and closing structure 48 can be made of a hard material, and the first opening and closing structure 48 is rotatably connected to the second frame 42. A torsion spring can be provided on the first opening and closing structure 48, and the torsion spring is used to provide the first opening and closing structure 48 with an elastic force to keep the first free end 482 in contact with the second frame 42, so that the second drain port 423 and the third drain port 424 remain closed, which can ensure that when the sewage tank 20 is in use, the second drain port 423 and the third drain port 424 are in a closed state, and when drainage is required, the sewage can be discharged through the drain port 423. Gravity causes the first free end 482 to swing relative to the first connecting end 481 in a direction away from the second frame 42 to open the second drainage port 423 and the third drainage port 424. When sewage is used to flush the first detent channel 472 and the second detent channel 473, the impact force of the sewage can cause the first free end 482 to swing relative to the first connecting end 481 in a direction away from the second frame 42. The user can also manually rotate the first opening and closing structure 48 to open the second drainage port 423 and the third drainage port 424.

[0063] It should also be noted that the first opening and closing structure 48 can also be made of soft material, and the soft material can be silicone, rubber or soft plastic and the like, so that when the fan 60 is started, the first free end 482 can be in closer contact with the second frame 42 under the suction of the airflow generated by the fan 60, and when draining water, the first free end 482 can be more easily swung in a direction away from the second frame 42 relative to the first connection end 481 under the action of the gravity of the liquid to open the second drain port 423 and the third drain port 424, making the drainage operation more convenient.

[0064] In one embodiment of the present application, the second opening and closing structure 49 is arranged on the outside of the first frame 41, and the second opening and closing structure 49 has a second connecting end 491 and a second free end 492 arranged opposite to the second connecting end 491. The second connecting end 491 is connected to the first frame 41, and the second free end 492 is used to swing relative to the second connecting end 491 in a direction away from the first frame 41 under the action of liquid. It should be noted that when the sewage tank 20 is in use, the second free end 492 naturally fits with the second frame 42 to close the first drain port 411. When the fan 60 is started, the second free end 492 is in closer contact with the first frame 41 under the suction of the airflow generated by the fan 60, thereby ensuring that the first drain port 411 is in a closed state. When there is too much sewage on the first frame 41, the second opening and closing structure 49 can open the first drain port 411 under the pressure of the sewage; when the fan 60 stops working or the first slow flow chamber 46 is flushed, the second free end 492 can swing relative to the second connecting end 491 in a direction away from the first frame 41 under the action of the gravity and impact force of the liquid to open the first drain port 411.

[0065] Specifically, the second opening and closing structure 49 can be made of a hard material, and the second opening and closing structure 49 is rotatably connected to the first frame 41. A torsion spring can also be arranged on the second opening and closing structure 49, and the torsion spring on the second opening and closing structure 49 is used to provide the second opening and closing structure 49 with an elastic force to keep the second free end 492 in contact with the first frame 41 so that the first drain port 411 remains closed, which can ensure that when the sewage tank 20 is in use, the second drain port 423 and the third drain port 424 are in a closed state. When drainage is required, the second free end 492 can be swung relative to the second connection end 491 in a direction away from the first frame 41 by the gravity of the sewage to open the first drain port 411. When the first frame 41 is flushed with sewage, the second free end 492 can be swung relative to the second connection end 491 in a direction away from the first frame 41 by the impact force of the sewage. The user can also manually rotate the second opening and closing structure 49 to open the first drain port 411.

[0066] It should also be noted that the second opening and closing structure 49 can also be made of soft material, and the soft material can be silicone, rubber or soft plastic and the like, so that when the fan 60 is started, the second free end 492 can be in closer contact with the first frame 41 under the suction of the airflow generated by the fan 60, and when draining water, the second free end 492 can be more easily swung relative to the second connection end 491 in a direction away from the first frame 41 under the action of the gravity of the liquid to open the first drain port 411, making the drainage operation more convenient.

[0067] In one embodiment of the present application, the bottom wall surface of the first slow flow chamber 46 is tilted downward along the direction from the inlet of the first slow flow chamber 46 to the outlet 461 of the first slow flow chamber 46. It can be understood that the first drain port 411 is arranged close to the outlet 461 of the first slow flow chamber 46, so that the bottom wall surface of the first slow flow chamber 46 is tilted downward in the direction close to the first drain port 411, so that the sewage in the first slow flow chamber 46 can flow to the first drain port 411 under the action of gravity and be discharged to the second cavity 312 through the first drain port 411.

[0068] Specifically, when the sewage tank 20 is applied to a cleaning device, and the cleaning device is in Figure 8 In the working posture shown, the bottom wall of the first slow flow chamber 46 is inclined downward along the direction from the entrance of the first slow flow chamber 46 to the outlet 461 of the first slow flow chamber 46, so that the sewage in the first slow flow chamber 46 can flow toward the first drain port 411 under the action of gravity and be discharged to the second chamber 312 through the first drain port 411.

[0069] Continue to see Figure 1 , Figure 4 and Figure 5As shown, in some embodiments of the present application, a filter 53 is provided on the cover body 40, and in the flow path of the airflow, the filter 53 is located downstream of the filter hole 441. It can be understood that when the airflow flows from the sewage chamber 31 to the air outlet 432a, the airflow will pass through the filter hole 441 and the filter 53 in sequence, and through the dual filtering effect of the filter hole 441 and the filter 53, most of the solid dirt (such as dust particles, hair, and cotton wool, etc.) carried in the airflow can be intercepted, and the solid dirt carried in the airflow can be prevented from being discharged from the cover body 40 to cause secondary pollution.

[0070] Among them, the filtering accuracy of the filter element 53 can be greater than the filtering accuracy of the filtering hole 441. It can be understood that the greater the filtering accuracy of the filter element 53, the smaller the filter hole of the filter element 53 and the stronger the filtering effect. The filtering accuracy of the filtering hole 441 is relatively small, which can play a role of coarse filtering, with low cost and convenient cleaning and washing. The filtering accuracy of the filter element 53 is relatively high, and the filter element 53 can play a role of fine filtering, which can better intercept solid dirt. The filtering hole 441 can block fabric-like garbage such as hair and cotton wool and large particles of dust, and prevent fabric-like garbage and large particles of dust from adhering to the filter element 53, which can reduce the number of cleaning times and cleaning difficulty of the filter element 53, and can reduce the loss of the filter element 53, which is convenient for users to use and can also reduce the cost of use.

[0071] Specifically, the filter element 53 can be filter cotton with smaller pores. The filter cotton can be directly washed with water, is not easily worn out, has a long service life, and can save consumables for users. The present application does not specifically limit the specific size of the filter hole 441 and the specific size of the filter hole of the filter element 53, and can be selected according to actual needs.

[0072] It should be noted that the air outlet 432a is the place where the air flow must pass, and the air outlet 432a is relatively narrow. The air flow is more concentrated when passing through the air outlet 432a. Therefore, in some implementations of the present application, the filter element 53 can be set at the air outlet 432a or close to the air outlet 432a, so that the size of the filter element 53 can be reduced and the cost of consumables can be reduced on the basis of the filter element 53 can play a good filtering role.

[0073] In one embodiment of the present application, the filter element 53 is detachably connected to the cover body 40, so that the filter element 53 can be removed and replaced separately; wherein, the detachable connection method between the filter element 53 and the cover body 40 includes but is not limited to a snap connection, a threaded connection or a snap connection.

[0074] In an embodiment of the present application, the fourth extension portion 432 is provided with a second vent 432b in communication with the air outlet 432a, and the airflow can flow out of the cover body 40 through the second vent 432b after passing through the air outlet 432a. Further, the fourth extension portion 432 is provided with a limiting groove 432c, which extends from the air outlet 432a to the second vent 432b, and the filter 53 is installed in the limiting groove 432c; the limiting groove 432c can provide installation space and limit for the filter 53, making the installation of the filter 53 more convenient.

[0075] It is understandable that in some embodiments, the filter element 53 may be omitted, that is, a single-layer filtering form of the filter holes 441 may be adopted.

[0076] In summary, for the sewage tank 20 of the present embodiment, the airflow will sequentially pass through the sewage inlet 331a, the sewage outlet 331b, the filter hole 441, the inlet of the first slow flow chamber 46, the outlet 461 of the first slow flow chamber 46, the first vent 471, the first baffle channel 472, the second baffle channel 473, the air outlet 432a and the second vent 432b, and the airflow will first pass through the filter hole 441 for the first layer of filtration before entering the first slow flow chamber 46, and pass through the filter element 53 for the second layer of filtration after flowing out of the second baffle channel 473. When the sewage tank 20 is applied to the cleaning equipment, the airflow enters the air inlet 61 (such as Figure 8 ), the airflow is double-filtered by the cover 40 before entering the air inlet 61 (such as Figure 8 ) before the fan 60 is blown, the cover body 40 will also perform water and gas separation, which not only prevents solid dirt from entering the fan 60, but also reduces the sewage entering the fan 60, effectively protects the fan 60, improves the performance of the fan 60, and extends the service life of the fan 60.

[0077] like Figures 4 to 6 As shown, in one embodiment of the present application, the cover body 40 further includes a pressure cover 452, which covers the limiting groove 432c, and abuts against the filter element 53, so as to provide a limit for the filter element 53 by using the pressure cover 452, so as to prevent the filter element 53 from moving out of the limiting groove 432c due to factors such as shaking during the use of the sewage tank 20. Specifically, the pressure cover 452 covers the second vent 432b, and a through hole communicating with the limiting groove 432c is also provided on the pressure cover 452, so that the limiting groove 432c is communicated with the outside through the through hole.

[0078] In one embodiment of the present application, the cover body 40 further includes a second sealing member 453, which is located at the joint between the first extension portion 421 and the third extension portion 431, and the first extension portion 421 and the third extension portion 431 are sealed and connected through the second sealing member 453, so as to improve the sealing performance of the joint between the first extension portion 421 and the third extension portion 431, and prevent the airflow from entering the first deflection channel 472 through the joint between the first extension portion 421 and the third extension portion 431. The second sealing member 453 can be made of metal, rubber, silicone or plastic; illustratively, the second sealing member 453 can be arranged along the circumference of the cover body 40, that is, the second sealing member 453 is a sealing ring, so as to further improve the sealing performance of the joint between the first extension portion 421 and the third extension portion 431.

[0079] In one embodiment of the present application, the cover 40 further includes a third sealing member 454, which is disposed on the third frame 43 and abuts against the inner peripheral wall of the sewage chamber 31 to improve the sealing performance between the cover 40 and the inner peripheral wall of the sewage chamber 31, and prevent the sewage in the sewage chamber 31 from flowing out of the sewage chamber 31 through the gap between the cover 40 and the inner peripheral wall of the sewage chamber 31. The preparation material of the third sealing member 454 can be metal, rubber, silicone or plastic; illustratively, the third sealing member 454 can be disposed around the circumference of the third frame 43, that is, the third sealing member 454 is a sealing ring, so as to further improve the sealing performance between the cover 40 and the inner peripheral wall of the sewage chamber 31.

[0080] Furthermore, a second sealing groove 433 is disposed on the third frame 43 , and a third sealing member 454 is disposed in the second sealing groove 433 to reduce the overall volume of the cover 40 and the gap between the cover 40 and the inner peripheral wall of the sewage chamber 31 .

[0081] In one embodiment of the present application, the cover body 40 also includes a handle 455, which is rotatably connected to the third frame 43. The handle 455 can be rotated relative to the third frame 43 for storage and unfolding. The user can lift the cover body 40 from the box body 30 by holding the handle 455, so that the cover body 40 and the box body 30 can be separated more easily.

[0082] In the second aspect, based on the above-mentioned sewage tank 20, the present application also provides a cleaning device, such as Figure 7 and Figure 8 As shown, the cleaning device comprises a body 10, a fan 60 and a sewage tank 20 in any of the above embodiments. The cleaning device can clean the surface to be cleaned of articles such as blankets, sofas or fabric products.

[0083] Among them, the body 10 has a sewage suction port 111, and the body 10 is the main structure of the cleaning equipment. The body 10 can provide installation space and support for devices such as the sewage tank 20 in the cleaning equipment; illustratively, the material of the body 10 includes but is not limited to plastic or metal. Exemplarily, the material of the body 10 can be plastic material to reduce the weight of the body 10 itself, thereby reducing the overall weight of the cleaning equipment, so that the user can use the cleaning equipment to clean the surface to be cleaned. It can be understood that in order to improve the structural strength of the body 10, the body 10 can also be made of metal material, or a plurality of metal reinforcements can be set in the plastic body 10 to make the structural strength of the body 10 higher, thereby reducing the probability of damage to the body 10 and extending the service life of the cleaning equipment.

[0084] The sewage tank 20 is mounted on the machine body 10, and the sewage suction port 111 is connected to the sewage inlet 331a; it should be noted that when the cleaning device is used to clean the surface to be cleaned, the sewage suction port 111 is brought into contact with the surface to be cleaned, and the dirt on the surface to be cleaned is sucked into the sewage chamber 31 through the sewage suction port 111 for storage. Exemplarily, the sewage tank 20 can be detachably connected to the machine body 10, so that after the sewage tank 20 is full of water, the user can disassemble the sewage tank 20 to pour out the sewage in the sewage tank 20 and clean the sewage tank 20. The detachable connection between the sewage tank 20 and the machine body 10 includes but is not limited to a snap connection, a threaded connection, or a buckle connection.

[0085] The fan 60 is installed on the body 10, and the air inlet 61 of the fan 60 is connected to the air outlet 432a. Figure 8 As shown, Figure 8 The direction indicated by the dashed arrow is the flow direction of the airflow generated by the fan 60. The airflow generated by the fan 60 passes through the sewage suction port 111, the sewage chamber 31, the filter hole 441, the entrance of the first slow flow chamber 46, the outlet 461 of the first slow flow chamber 46, the first vent 471, the first baffle channel 472, the second baffle channel 473, the air outlet 432a, the second air outlet 432b and the air inlet 61 in sequence. The fan 60 is used to form a negative pressure in the sewage chamber 31, thereby forming a negative pressure at the sewage suction port 111, so that the sewage suction port 111 has suction force to absorb dirt. The specific size and specific model of the fan 60 can be selected according to actual needs, and this application does not make specific restrictions.

[0086] Continue to refer to Figure 8 As shown, in some embodiments of the present application, the body 10 also has a sewage suction channel 11, the first end of the sewage suction channel 11 is a sewage suction port 111, and the second end of the sewage suction channel 11 is connected to the sewage inlet 331a. When the cleaning equipment is cleaning, the dirt is sucked into the sewage suction channel 11 through the sewage suction port 111, and then enters the sewage chamber 31 through the sewage inlet 331a.

[0087] Continue to refer to Figure 7 and Figure 8 As shown, in some embodiments of the present application, the body 10 also has a liquid spray port 12, and the cleaning device also includes a clean water tank 70 disposed on the body 10, and the clean water tank 70 has a clean water chamber 71 connected to the liquid spray port 12. It should be noted that the clean water chamber 71 is used to store cleaning liquids such as clean water, disinfectant, or a mixture of clean water and detergent. When the cleaning device is used to clean the surface to be cleaned, dry garbage (such as dust particles, noodles, kitchen waste, pet feces, etc.), liquid garbage (such as urine, sewage, etc.) or dry and wet mixed garbage on the surface to be cleaned can be directly sucked into the sewage chamber 31 through the sewage suction port 111; when the cleaning device is used to clean the surface to be cleaned, the cleaning liquid in the clean water chamber 71 can also be first sprayed onto the surface to be cleaned through the liquid spray port 12, and the cleaning liquid wets the dirt (such as dust particles, noodles, kitchen waste, pet feces, etc.) on the surface to be cleaned, and then the dry and wet mixed garbage can be sucked into the sewage chamber 31 through the sewage suction port 111, so that the surface to be cleaned can be cleaned more cleanly.

[0088] Continue to refer to Figure 7 and Figure 8 As shown, in some embodiments of the present application, the cleaning device is a handheld cleaning device, which is mainly used for wet and dry cleaning of fabrics, carpets, sofas, etc. Specifically, the body 10 includes a gripping portion 13 and a cleaning portion 14, and the gripping portion 13 is connected to the cleaning portion 14; it should be noted that the gripping portion 13 is a portion of the body 10 for the user to grip, and the gripping portion 13 can facilitate the user to grip the body 10 to operate the cleaning device.

[0089] Among them, one of the sewage tank 20 and the clean water tank 70 is arranged on the cleaning part 14, and the other of the sewage tank 20 and the clean water tank 70 is arranged on the holding part 13, so that the clean water tank 70 and the sewage tank 20 have a sufficient distance to prevent the clean water tank 70 and the sewage tank 20 from occupying the space required by each other, so that the volume of the sewage tank 20 and the clean water tank 70 can be set larger, the capacity of the sewage chamber 31 and the clean water chamber 71 can be increased, and the sustainable working time of the cleaning equipment can be improved.

[0090] Furthermore, the sewage tank 20 is arranged on the cleaning part 14, and the clean water tank 70 is arranged on the gripping part 13. It should be noted that the cleaning part 14 is the main structure of the body 10, so the volume of the cleaning part 14 is usually larger than the volume of the gripping part 13. By arranging the sewage tank 20 on the cleaning part 14, the volume of the sewage tank 20 can be set larger, and the capacity of the sewage chamber 31 can be further increased, so that the sustainable working time of the cleaning device can be further improved.

[0091] In addition, as the user uses the cleaning device for cleaning, the cleaning liquid in the clean water tank 70 will gradually decrease, causing the weight of the gripping portion 13 to gradually decrease, so that the force on the user's hand will gradually decrease, while the water in the dirty water tank 20 will gradually increase, causing the weight of the cleaning portion 14 to gradually increase, further making the cleaning portion 14 more closely fit the surface to be cleaned, thereby improving the cleaning effect of the cleaning device on the surface to be cleaned.

[0092] In one embodiment of the present application, the sewage tank 20 can be detachably connected to the cleaning part 14, and the sewage tank 20 can be detachably connected to the cleaning part 14 by means of snap-fitting or the like, so that it is convenient to remove the sewage tank 20 from the cleaning part 14, so as to clean the sewage tank 20; the clean water tank 70 can be detachably connected to the grip part 13, and the clean water tank 70 can also be detachably connected to the cleaning part 14 by means of snap-fitting or the like, so that it is convenient for the user to remove the clean water tank 70 from the grip part 13, so that the user can add cleaning liquid into the clean water tank 70.

[0093] Continue to refer to Figure 7 and Figure 8 As shown, in some embodiments of the present application, a first mounting groove 131 is provided on the holding portion 13, and the clean water tank 70 is provided in the first mounting groove 131; a second mounting groove 141 is provided on the cleaning portion 14, and the sewage tank 20 is provided in the second mounting groove 141. The space between the holding portion 13 and the cleaning portion 14 can be fully utilized, so that the structure of the cleaning equipment is more compact, the overall volume of the cleaning equipment is reduced, and the use and storage of the cleaning equipment are convenient.

[0094] Furthermore, the grip portion 13 is provided with a clearance opening 132 for inserting a finger, and the clearance opening 132 is arranged along the first direction (ie Figure 7 The first mounting groove 131 is provided on the inner side wall of the avoidance opening 132. It should be noted that the avoidance opening 132 penetrates the gripping portion 13 to form a structure similar to a handle, which is used for inserting fingers into the avoidance opening 132 and holding the gripping portion 13 when holding the gripping portion 13, so that the user can hold the gripping portion 13 more conveniently. The first mounting groove 131 is designed on the inner side wall of the avoidance opening 132, so that the inner space of the gripping portion 13 can be fully utilized, and the overall volume of the cleaning device can be reduced, while preventing the clean water tank 70 from colliding with other objects during the use of the cleaning device.

[0095] Furthermore, the first mounting groove 131 is disposed on the bottom side wall of the inner side wall of the avoidance opening 132. It should be noted that the bottom side wall of the inner side wall of the avoidance opening 132 is the side wall located at the bottom of the inner side wall of the avoidance opening 132 when the cleaning device is used to clean the surface to be cleaned, which can prevent the clean water tank 70 from being separated from the gripping portion 13 under the action of gravity. In other embodiments, the clean water tank 70 can also be disposed at the bottom of the gripping portion 13, that is, disposed on the side of the gripping portion 13 away from the avoidance opening 132.

[0096] Specifically, Figure 7 As shown, the clean water tank 70 is connected to the gripping portion 13 by sliding along the first direction XX. It can be understood that one side of the first installation groove 131 along the first direction XX is a notch. When loading and unloading the clean water tank 70, by sliding the clean water tank 70 relative to the gripping portion 13 along the first direction XX, the clean water tank 70 can be moved in and out of the first installation groove 131 through the notch, making the installation of the clean water tank 70 in the first installation groove 131 more convenient.

[0097] Specifically, the clean water tank 70 includes a clean water tank 70 body and a plug body. The clean water tank 70 body has a clean water cavity 71 and a liquid replenishing port connected to the clean water cavity 71. Liquid can be replenished into the clean water cavity 71 through the liquid replenishing port. The plug body is used to open and close the liquid replenishing port.

[0098] In one embodiment of the present application, the fan 60 can be installed in the cleaning section 14. It is understandable that the air inlet 61 of the fan 60 is generally connected to the air outlet 432a through the ventilation duct. By installing the fan 60 and the sewage tank 20 on the cleaning section 14, the length of the ventilation duct between the air inlet 61 of the fan 60 and the air outlet 432a of the cover 40 can be shortened, and the residual amount of sewage and dust in the ventilation duct can be reduced, and a large amount of sewage and dust can be prevented from remaining in the ventilation duct, resulting in blockage of the ventilation duct, which can improve the reliability of the cleaning equipment. Further, the length of the ventilation duct is less than 40 mm to ensure that the length of the ventilation duct is short, and the length of the ventilation duct can be 38 mm, 30 mm, 25 mm, 10 mm or other values. Further, the part of the fan 60 with the air inlet 61 fits the cover 40 to minimize the length of the ventilation duct.

[0099] In one embodiment of the present application, the gripping portion 13 is located at the rear side of the cleaning portion 14, and the second mounting groove 141 is recessed from the cleaning portion 14 toward the gripping portion 13. It should be noted that the rear side refers to the side of the cleaning device close to the user when the user uses the cleaning device to clean the surface to be cleaned. Figure 8 For example, in Figure 8In the figure, the rear side is the right side. By arranging the holding portion 13 at the rear side of the cleaning portion 14, the user can hold the holding portion 13 more conveniently. In addition, the clean water tank 70 and the sewage tank 20 respectively arranged on the holding portion 13 and the cleaning portion 14 can have a larger spacing to provide sufficient space for the arrangement of the second mounting groove 141. On the basis of reducing the overall volume of the cleaning equipment, the sewage tank 20 can be arranged with a larger volume.

[0100] Continue to refer to Figure 8 As shown, in some embodiments of the present application, the gripping portion 13 has a accommodating cavity 133, and the cleaning device further includes a battery assembly 81, which is installed in the accommodating cavity 133; the battery assembly 81 is used to power electrical devices in the cleaning device, such as the fan 60, and the battery in the battery assembly 81 can be a storage battery. The present application does not specifically limit the type and quantity of the battery. By arranging the battery assembly 81 in the accommodating cavity 133 of the gripping portion 13, the battery assembly 81 can be prevented from occupying the setting space of the sewage tank 20, so that the sewage tank 20 has more setting space, and the weight distribution of the cleaning device can also be balanced.

[0101] Among them, a charging port (not shown in the figure) is provided on the grip 13, and the charging port is electrically connected to the battery assembly 81. The charging port is used to charge the battery in the battery assembly 81, and the charging port is integrated on the grip 13. When charging the battery, the power supply can be directly connected to the charging port through a data cable, and there is no need to provide an additional base with a charging function for the cleaning device, which makes the battery charging more convenient, and can also reduce the packaging and transportation volume of the cleaning device, and reduce the overall cost of the cleaning device; the charging port can be preferably a Type-C interface, so that the cleaning device has a fast charging function, and no specific customized charger is required; of course, according to actual needs, the charging port can also be a Mini USB interface or a Lightning interface, etc. Of course, in other embodiments, the charging mode can also be set to a contact charging mode. Specifically, the cleaning device includes a contact contact electrically connected to the battery assembly 81, and the cleaning device is equipped with a base, which includes a charging contact for electrically contacting the contact contact on the cleaning device and a charging circuit electrically connected to the charging contact. By connecting the mains power and the charging circuit, the battery assembly 81 is charged through the contact between the charging contact and the contact contact.

[0102] like Figure 8As shown, in some embodiments of the present application, the cleaning device further includes a water delivery component 82, which is installed in the body 10 and is used to deliver the liquid in the clean water chamber 71 to the liquid spraying port 12, so that the liquid in the clean water chamber 71 can be smoothly sprayed out through the liquid spraying port 12. The water delivery component 82 may be a pumping type water delivery component 82, through which the liquid in the clean water chamber 71 is drawn to the liquid spraying port 12; the water delivery component 82 may also be an air-inflating type water delivery component 82, through which the clean water chamber 71 is inflated, so that the liquid in the clean water chamber 71 is delivered to the liquid spraying port 12 under pressure.

[0103] Specifically, for the extraction type water delivery assembly 82, the water delivery assembly 82 includes a water pump 821 and a liquid infusion tube (not shown in the figure), the water pump 821 is connected to the liquid spraying port 12 and the clean water chamber 71 through the liquid infusion tube, the water pump 821 is used to provide power, and the liquid infusion tube is used to provide a flow channel for the liquid in the clean water chamber 71. Exemplarily, two liquid infusion tubes can be provided, the water inlet end of the water pump 821 is connected to the clean water chamber 71 through one liquid infusion tube, and the water outlet end of the water pump 821 is connected to the liquid spraying port 12 through another liquid infusion tube. For the air-inflated water delivery assembly 82, the water delivery assembly 82 includes a water pump 821, a vent and a liquid infusion tube, the exhaust port of the water pump 821 is connected to the clean water chamber 71 through the vent, and the clean water chamber 71 is connected to the liquid spraying port 12 through the liquid infusion tube.

[0104] In some embodiments of the present application, the cleaning device also includes a current detector (not shown in the figure) and an early warning component; the current detector is connected to the water pump 821, and the current detector is used to detect the working current of the water pump 821 when it is working; the early warning component is connected to the current detector, and when the detection result of the current detector indicates that the clean water tank 70 is in a liquid-deficient state and / or the infusion tube is in a blocked state, the early warning component activates an early warning.

[0105] It should be noted that the working current of the water pump 821 when it is working can be the input current or the output current of the water pump 821. When the cleaning liquid in the clean water chamber 71 of the clean water tank 70 is sufficient and the infusion tube is unobstructed, the water pump 821 works normally. When the cleaning liquid in the clean water chamber 71 is too little or / and the infusion tube is blocked, the water pump 821 cannot work normally, resulting in a change in the working current of the water pump 821. The working current of the water pump 821 when the cleaning liquid in the clean water chamber 71 is too little is different from the working current of the water pump 821 when the infusion tube is blocked. For example, when the water pump 821 works normally, the working current of the water pump 821 The current is 450mA±50mA. When the clean water tank 70 is in a water shortage state, the working current of the water pump 821 is 90mA±50mA. When the infusion tube is in a blocked state, the working current of the water pump 821 is 240mA±50mA. Therefore, the working current of the water pump 821 when it is working can be detected by the current detector, and according to the working current of the water pump 821 when it is working, it can be determined whether there is water in the clean water tank 70 and whether the state of the infusion tube is normal. When the clean water tank 70 is in a liquid shortage state and / or the infusion tube is in a blocked state, the early warning component can start an early warning according to the detection results, and can remind the user to add water and deal with the fault in time.

[0106] Specifically, the warning component may include a warning light group, and the warning light group may include one warning light or multiple warning lights. When the warning light group includes one warning light, different situations may be indicated by display states such as the color or flashing frequency of the warning light. For example, the warning light displays green when the water pump 821 is working normally, and displays yellow when the clean water tank 70 is in a water shortage state, and displays red when the infusion tube is in a blocked state. For another example, the warning light is always on when the water pump 821 is working normally, and the warning light flashes at a frequency of 1 Hz when the clean water tank 70 is in a water shortage state, and flashes at a frequency of 5 Hz when the infusion tube is in a blocked state. Of course, the warning light may also indicate different situations through other display states. When the warning light group includes multiple warning lights, different situations may be indicated by the display of different warning lights. For example, the first warning light is on when the water pump 821 is working normally, the second warning light is on when the clean water tank 70 is in a water shortage state, and the third warning light is on when the infusion tube is in a blocked state. In addition, when the cleaning device has a control panel 94 (such as Figure 7 ), display icons or animations corresponding to different states can also be set on the control panel 94, such as a normal display icon or animation corresponding to when the cleaning liquid in the clean water chamber 71 of the clean water tank 70 is sufficient and the infusion tube is in an unobstructed state, a water shortage icon or animation corresponding to when the cleaning liquid in the clean water chamber 71 is insufficient, and an infusion tube blockage icon or animation corresponding to when the infusion tube is in a blocked state.

[0107] Of course, according to actual needs, the warning component can also be other components, such as a voice broadcast component or a buzzer component that can remind the user.

[0108] It should also be noted that the early warning component can also be connected to the user's terminal device for communication. When the clean water tank 70 is short of liquid and / or the infusion tube is blocked, the early warning component sends an early warning message to the user terminal to remind the user to deal with the fault in time. The terminal device can be a mobile phone, tablet computer, desktop computer host, gaming device, electronic watch, electronic glasses, electronic helmet, electronic bracelet, electronic necklace, electronic clothing and other devices.

[0109] like Figure 8 As shown, in some embodiments of the present application, a third mounting groove 142 is provided at the bottom of the cleaning part 14, and the cleaning device further includes a cleaning component, which is provided in the third mounting groove 142 and is located at the rear side of the suction port 111, and the cleaning component is used to contact the surface to be cleaned. When the cleaning device is used to clean the surface to be cleaned, the cleaning component contacts the surface to be cleaned, and the cleaning component reciprocates on the surface to be cleaned, so that the solid waste on the surface to be cleaned can be separated from the object to be cleaned, and the solid waste is fully mixed with the liquid to achieve a better cleaning effect.

[0110] Wherein, the cleaning component is selected from the roller brush component 83 (such as Figure 8 ) and one of the flat brush assemblies (not shown in the figure), the roller brush assembly 83 includes a roller brush 831 rotatably connected to the cleaning part 14; the flat brush assembly includes a flat brush relatively fixed to the cleaning part 14.

[0111] It can be understood that when using the roller brush assembly 83, the roller brush 831 can rotate relative to the cleaning part 14. Compared with the flat brush, the roller brush 831 has a better cleaning effect on the uneven surface to be cleaned; when using the flat brush assembly, the flat brush is fixed on the cleaning part 14. Compared with the roller brush 831, the flat brush can apply greater pressure on the surface to be cleaned, and has a better cleaning effect on the smooth surface to be cleaned, and the flat brush has a better cleaning effect on the corners such as the edges of the wall. The roller brush assembly 83 and the flat brush assembly can be replaced with each other so that the cleaning equipment can adapt to different scenarios and needs.

[0112] It should also be noted that the roller brush assembly 83 also includes a first mounting frame 832, the roller brush 831 is mounted on the first mounting frame 832 and mounted on the cleaning portion 14 through the first mounting frame 832, and the first mounting frame 832 is detachably connected to the cleaning portion 14. In addition, the roller brush assembly 83 may also include a motor, which is used to drive the roller brush 831 to rotate. In some embodiments, the first mounting frame 832 may be omitted, and the roller brush 831 is directly mounted on the cleaning portion 14. Alternatively, in some embodiments, the motor may also be omitted, and the roller brush 831 rotates as the cleaning device moves on the surface to be cleaned.

[0113] Similarly, the flat brush can be directly mounted on the cleaning portion 14 , or the flat brush assembly can also include a second mounting frame, the flat brush is mounted on the second mounting frame and mounted on the cleaning portion 14 via the second mounting frame, and the second mounting frame is detachably connected to the cleaning portion 14 .

[0114] In one embodiment of the present application, the cleaning component also includes a pressable elastic reset button (not shown in the figure). When the elastic reset button is pressed, the elastic reset button is separated from the body 10, and the cleaning component can be separated from the body 10 at this time; when the pressure on the elastic reset button is released, the elastic reset button is reset and engaged with the body 10, thereby installing the cleaning component on the body 10.

[0115] Reference Figure 7 and Figure 8 As shown, in one embodiment of the present application, the body 10 further includes a nozzle cover 15 , which is located at the front side of the cleaning portion 14 and is detachably connected to the cleaning portion 14 , and the nozzle cover 15 and the cleaning portion 14 enclose a portion of the sewage suction channel 11 .

[0116] It is understandable that when dirt passes through the sewage suction channel 11, part of the dirt will adhere to the tube wall of the sewage suction channel 11, which may easily cause the sewage suction channel 11 to be blocked. Therefore, after the cleaning device completes cleaning, the sewage suction channel 11 needs to be cleaned. In the embodiment of the present application, when the sewage suction channel 11 needs to be cleaned, the suction nozzle cover 15 can be removed to expose part of the tube wall of the sewage suction channel 11. At this time, clean water can be used to directly rinse the suction nozzle cover 15 and the part of the cleaning part 14 that constitutes the sewage suction channel 11, making the cleaning of the sewage suction channel 11 more convenient and cleaner. Among them, the suction nozzle cover 15 can be detachably connected to the cleaning part 14 by a snap connection, and the suction nozzle cover 15 can also be detachably connected to the cleaning part 14 by a threaded connection or a magnetic connection.

[0117] Furthermore, the suction nozzle cover 15 and the cleaning portion 14 are combined to form a sewage suction port 111, so that cleaning at the sewage suction port 111 is more convenient and can be cleaned more thoroughly.

[0118] In one embodiment of the present application, Figure 7 and Figure 8 As shown, the liquid spray port 12 is located above the dirt suction port 111 . By raising the height of the liquid spray port 12 , the liquid spray port 12 has a larger liquid spray range when the cleaning device cleans the surface to be cleaned. Further, the liquid spray port 12 is located above the suction nozzle cover 15 .

[0119] Furthermore, in some embodiments, the liquid spray port 12 can be located in front of the dirt suction port 111. It can be understood that when the cleaning device cleans the surface to be cleaned, the cleaning device will move forward and backward and absorb dirt on the surface to be cleaned through the dirt suction port 111. By arranging the liquid spray port 12 in front of the dirt suction port 111, the liquid spray port 12 can spray liquid along the cleaning path, which can improve the cleaning efficiency. The body 10 also has an exhaust passage and an exhaust port 16 connected to the exhaust passage; the fan 60 also has an outlet 62 connected to the air inlet 61, and the outlet 62 is connected to the air inlet 61 and the exhaust passage. After the airflow generated by the fan 60 flows out from the air outlet 432a, it passes through the air inlet 61, the air outlet 62, the exhaust passage and the exhaust port 16 in sequence.

[0120] Reference Figure 7 and Fig. 9 As shown, in a specific embodiment, the cleaning device also includes a stain detection device 92 and a controller. The stain detection device 92 is arranged on the body 10 and is connected to the battery and the controller. The stain detection device 92 is used to emit light outside the body 10 to detect stains on the surface to be cleaned. When the user needs to find hidden stains on the surface to be cleaned of the fabric product, the stain detection device 92 can be turned on to allow the light emitted by the stain detection device 92 to irradiate the surface to be cleaned, thereby facilitating the user to find the hidden stains on the fabric product, and control the liquid spray port 12 to spray cleaning liquid on the hidden stains. Then, the cleaning component arranged at the bottom of the cleaning device can reciprocate on the surface to be cleaned, and the liquid carrying dirt can be recovered into the sewage tank 20 through the sewage suction port 111, thereby realizing the fixed-point cleaning of the hidden stains on the surface to be cleaned, which can improve the cleaning efficiency and reduce the probability of hidden stains remaining on the surface of the fabric product for a long time to cause bacterial growth; and different hidden stains can be removed with a more targeted cleaning liquid to improve the cleaning quality.

[0121] Continue to refer to Figure 7 and Fig. 9 As shown, in a specific embodiment, the cleaning device also includes a transparent protective member 93, which is connected to the body 10 and covers a stain detection device 92. The transparent protective member 93 is used to protect the stain detection device 92, so as to reduce the probability of damage to the stain detection device 92 and extend the service life of the stain detection device 92. The light emitted by the stain detection device 92 is emitted to the outside of the body 10 through the transparent protective member 93.

[0122] Furthermore, in order to improve the overall aesthetics of the cleaning device, the body 10 has a receiving groove 18 , the stain detection device 92 is disposed in the receiving groove 18 , and the transparent protective member 93 can be disposed at the notch of the receiving groove 18 .

[0123] Specifically, the stain detection device 92 is at least one of an ultraviolet stain detection device or a laser stain detection device. Exemplarily, when the stain detection device 92 is an ultraviolet stain detection device, such as an ultraviolet lamp, the wavelength of the ultraviolet light emitted by the ultraviolet stain detection device is greater than or equal to 360 mm and less than or equal to 370 mm, so that when the ultraviolet light emitted by the ultraviolet stain detection device is irradiated to the pet stains on the surface to be cleaned, it will induce a fluorescent reaction of the pet stains, so that the user can find the hidden pet stains according to the fluorescence, thereby facilitating the user to clean the hidden pet stains. Pet stains include at least urine stains and may also include feces, and in order to reduce the influence of the transparent protective member 93 on ultraviolet light, the transparent protective member 93 may be an acrylic lampshade that is highly transparent to ultraviolet light and resistant to ultraviolet lamps. Of course, the stain detection device 92 may also be a laser stain detection device for detecting dust stains.

[0124] Reference Figure 7 and Fig. 9 As shown, in a specific embodiment, the stain detection device 92 is arranged on the front side of the body 10, so that when the user drives the cleaning device to move forward through the grip 13, the stain detection device 92 can be turned on to detect stains on the surface to be cleaned in front, or when the user lifts the cleaning device through the grip 13, the stain detection device 92 can be used to detect stains on the surface to be cleaned.

[0125] Specifically, the stain detection device 92 is arranged on the cleaning part 14 and is located on the side of the cleaning part 14 away from the holding part 13, so that when the user drives the cleaning device forward through the holding part 13, the stain detection device 92 can be used to detect stains on the surface to be cleaned in front; or when the user lifts the cleaning device through the holding part 13, the cleaning part 14 rotates with the user's hand as the axis under the action of gravity, and the stain detection device 92 can also be used to detect stains on the surface to be cleaned.

[0126] Please refer to Figure 7 In a specific embodiment, the height of the liquid spray port 12 relative to the surface to be cleaned is higher than the height of the sewage suction port 111 relative to the surface to be cleaned, and the stain detection device 92 is located between the sewage suction port 111 and the liquid spray port 12 relative to the height of the surface to be cleaned, so that the stain detection device 92 is closer to the surface to be cleaned, and the light spot of the stain detection device 92 on the surface to be cleaned can have a larger area, thereby improving the efficiency of users in finding stains.

[0127] Please refer to Figure 7Furthermore, the distance between the stain detection device 92 and the bottom of the body 10 is a first height H1, and the first height H1 is greater than or equal to 26 mm and less than or equal to 32 mm, so that when the cleaning device is used to clean the surface to be cleaned, the stain detection device 92 has a larger area of ​​light spot on the surface to be cleaned, which can improve the efficiency of users in finding stains. If the first height H1 is less than 26 mm, the stain detection device 92 will be too close to the surface to be cleaned, resulting in a smaller light spot area of ​​the stain detection device 92 on the surface to be cleaned, resulting in a lower efficiency for users to find stains. If the first height H1 is greater than 32 mm, the stain detection device 92 will be far away from the surface to be cleaned, resulting in a larger light spot area of ​​the stain detection device 92 on the surface to be cleaned, resulting in a weaker fluorescent reaction of the induced pet stains, which is inconvenient for users to find stains.

[0128] In a specific embodiment, the cleaning device also includes a control panel 94 (such as Figure 7 ), the control panel 94 is arranged on the machine body 10 and connected to the controller, and is used to send a control signal to the controller according to the user's operation, so that the controller controls the stain detection device 92 to be turned on or off. When the stain detection device 92 is used to detect hidden stains on the surface to be cleaned, the stain detection device 92 can be turned on by operating the control panel 94, so as to use the light spot irradiated by the stain detection device 92 to the surface to be cleaned to find hidden stains, which can improve the cleaning efficiency; after cleaning, the user operates the control panel 94 to control the stain detection device 92 to be turned off, so as to reduce the power consumption of the battery assembly 81 and extend the service life of the stain detection device 92.

[0129] It is not difficult to understand that in other embodiments, the cleaning device may also be a floor scrubber or a cleaning robot, which is not the only limitation here.

[0130] In other embodiments, when the cleaning device is a cleaning robot, the stain detection device 92 can be set on the head of the cleaning robot to emit detection light to the surface to be cleaned in front of the cleaning robot. When stains are detected on the surface to be cleaned, the cleaning robot can focus on cleaning the area where the stains are located, such as reciprocating cleaning, or the cleaning robot can also bypass the area where the stains are located to avoid the cleaning robot from being stained with odor. The specific execution action of the cleaning robot can be determined according to the actual situation, and is not limited here.

[0131] Specifically, Figure 8 As shown, the cleaning device further comprises a condensation sensor 17 .

[0132] Among them, the condensation sensor 17 is used for humidity detection, and the condensation sensor 17 can be arranged in the exhaust passage. Exemplarily, the condensation sensor 17 can also be arranged on the air outlet 62. Exemplarily, the condensation sensor 17 can also be arranged on the exhaust outlet 16. It can be understood that the condensation sensor 17 can be arranged at the critical position between the air outlet 62 and the exhaust passage, part of the condensation sensor 17 is located at the air outlet 62, and the rest is located in the exhaust passage; similarly, the condensation sensor 17 can also be arranged at the critical position between the exhaust air duct and the exhaust outlet 16.

[0133] The controller is disposed in the body 10 and connected to the fan 60 and the condensation sensor 17 ; when the detection result of the condensation sensor 17 indicates that the sewage tank 20 is full of water, the controller is used to control the fan 60 to stop running.

[0134] In the embodiment of the present application, the controller controls the fan 60 to operate, thereby forming a negative pressure in the sewage suction channel 11, the sewage tank 20 and the sewage suction port 111, so that the sewage can enter the sewage tank 20 through the sewage suction port 111 and the sewage inlet 331a in sequence, so that the sewage can be temporarily stored in the sewage tank 20. Since the airflow entering the body 10 through the sewage suction port 111 will enter the fan 60 through the sewage tank 20, and then be discharged to the outside of the body 10 from the exhaust port 16 through the exhaust channel, the airflow entering the exhaust channel from the fan 60 will carry some sewage, and the sewage will condense and adhere to the condensation sensor 17 during the movement. The more sewage in the sewage tank 20, the more sewage is carried by the airflow entering the exhaust channel from the fan 60. When the detection result of the condensation sensor 17 indicates that the sewage tank 20 is full of water, the controller controls the fan 60 to stop running to prevent sewage with high humidity from entering the fan 60, thereby preventing the rust of internal components of the fan 60 and extending the service life of the fan 60. Compared with using an electrode sheet or a float to detect the liquid level in the sewage tank 20, it can eliminate the misjudgment of the liquid level caused by the shaking of the cleaning equipment, thereby improving the liquid level detection accuracy of the sewage tank 20, and the structure is also simpler.

[0135] like Figure 8 As shown, in one embodiment of the present application, the condensation sensor 17 is arranged in the exhaust passage and is closer to the air outlet 62 than the exhaust port 16, so that the humidity at the air outlet 62 is relatively high, that is, when there is a lot of sewage carried in the air flow, the probability of sewage adhering to the surface of the condensation sensor 17 is relatively high, thereby improving the accuracy of humidity detection of the condensation sensor 17; and because the condensation sensor 17 is closer to the air outlet 62 than the exhaust port 16, the influence of the external environment humidity on the detection accuracy of the condensation sensor 17 can be reduced, thereby further improving the detection accuracy of the condensation sensor 17. Of course, in other embodiments, the condensation sensor 17 can also be closer to the exhaust port 16 than the air outlet 62.

[0136] like Figure 8 As shown, in a specific embodiment, along the extension direction of the exhaust channel, the air outlet 62 and the condensation sensor 17 have a first distance L1, and the first distance L1 is greater than or equal to 4 mm and less than or equal to 6 mm, so that the sewage carried in the air flow flowing out through the air outlet 62 can easily contact the condensation sensor 17, thereby improving the detection accuracy of the condensation sensor 17.

[0137] In one embodiment of the present application, the battery assembly 81 is disposed in the body 10 and can supply power to the controller, the fan 60 and the condensation sensor 17, so that the cleaning device can support wireless use to improve the convenience of use of the cleaning device.

[0138] In a specific embodiment, the resistance growth rate of the dew sensor 17 when the humidity in the exhaust passage is greater than a preset value is greater than the resistance growth rate of the dew sensor 17 when the humidity in the exhaust passage is less than or equal to the preset value, so that the dew sensor 17 is more sensitive to high humidity, thereby improving the accuracy of the dew sensor 17 in detecting that the sewage tank 20 is full of water.

[0139] Please refer to Fig.10 As shown, in a specific embodiment, the condensation sensor 17 includes a voltage divider circuit 171 and a probe 172, the voltage divider circuit 171 has a power access terminal 171a, a ground terminal 171b and a voltage divider output terminal 171c, the power access terminal 171a is connected to the battery, the ground terminal 171b is grounded, and the voltage divider output terminal 171c is connected to the controller; the probe 172 is arranged in the exhaust channel, the probe 172 has a first pin 172a and a second pin 172b, the first pin 172a is connected to the voltage divider output terminal 171c, and the second pin 172b is grounded.

[0140] For example, Fig.11 The change curve shown is a change curve with the humidity in the exhaust passage as the horizontal coordinate and the resistance of the probe 172 as the vertical coordinate. When the humidity in the exhaust passage is greater than the preset value, the slope of the change curve is greater than the preset slope; when the slope of the change curve is greater than the preset slope, the controller controls the fan 60 to stop running. Among them, the thin solid line represents the change curve of the maximum resistance of the probe 172 as the humidity in the exhaust passage changes, the thick solid line represents the change curve of the average resistance of the probe 172 as the humidity in the exhaust passage changes, and the dotted line represents the change curve of the minimum resistance of the probe 172 as the humidity in the exhaust passage changes. In other embodiments, the change curve can also be a change curve with the humidity in the exhaust passage as the horizontal coordinate and the voltage of the voltage divider output terminal 171c as the vertical coordinate.

[0141] Please refer to Fig.10 and Fig.11Specifically, the preset slope can be that when the slope of the change curve is greater than or equal to, the humidity in the corresponding exhaust duct is greater than or equal to 90%. At this time, the detection result of the condensation sensor 17 indicates that the sewage tank 20 is full of water, and the controller controls the fan 60 to stop running.

[0142] Please refer to Fig.10 and Fig.12 In a specific embodiment, the voltage divider circuit 171 includes a first resistor R1 and a second resistor R2, the first resistor R1 and the second resistor R2 are connected in series between the power access terminal 171a and the ground terminal 171b, and the voltage divider output terminal 171c is arranged between the first resistor R1 and the second resistor R2. The probe 172 is powered by the voltage divided by the first resistor R1 and the second resistor R2, which can prevent the voltage on the pin of the probe 172 from being greater than the electrolysis voltage of the liquid, thereby preventing the liquid from being electrolyzed at the pin of the probe 172 to affect the electrical connection stability of the pin, thereby increasing the detection service life of the condensation sensor 17 and increasing the service life of the cleaning equipment.

[0143] Continue to refer to Figure 8 As shown, in a specific embodiment, the cleaning device also includes a prompt device 91, which is arranged on the body 10 and connected to the controller; wherein, when the detection result of the condensation sensor 17 indicates that the sewage tank 20 is full of water, the controller is also used to control the prompt device 91 to send a prompt message, so that the user can clean the sewage tank 20 according to the prompt message, thereby facilitating the next use of the cleaning device. Exemplarily, the prompt device 91 includes at least one of a display or a speaker. Exemplarily, when the prompt device 91 is a display, the prompt message is an image or light message. When the prompt device 91 is a speaker, the prompt message is an audio message.

[0144] The above are only preferred embodiments of the present application and are not intended to limit the present application. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present application should be included in the protection scope of the present application.
