Fig. 3 shows a recycling bin 10 according to an embodiment of the present application, wherein a main body 1 of the recycling bin 10 has a semi-cylindrical shape, and the main body 1 defines a storage space 11 for storing dirt. The recovery tank 10 further includes an air intake passage 12 for guiding dirt outside the storage space 11 into the storage space 11 through the air intake passage 12. At least part of the air intake passage 12 may be provided in the storage space 11, or may be provided outside the storage space 11, and may be adjusted according to the shape of the recovery tank 10 without limitation thereto. The air outlet channel 14 is used for guiding the air flow in the storage space 11 to flow out of the storage space 11 from the air outlet channel 14. At least part of the air outlet channel 14 may be disposed outside the storage space 11 or all of the air outlet channel may be disposed outside the storage space 11, and may be adjusted according to the shape of the recovery tank 10 without limitation. In the embodiment shown in fig. 6, the inlet channel 12 and the outlet channel 14 are two substantially parallel pipes, which are disposed in the storage space 11 and are located in the middle of the storage space 11.
Referring to fig. 6-9, in order to prevent or minimize the occurrence of water spray in the recovery tank 10 during operation, a pressure equalizing chamber 2 is provided between the inlet channel 12 and the outlet channel 14, the pressure equalizing chamber 2 comprising an air flow inlet and an air flow outlet 23, the air flow outlet 23 being in fluid communication with the outlet channel 14, the air flow inlet comprising a plurality of through holes 24, the plurality of through holes 24 being substantially horizontally spaced apart, the horizontal directions being not strictly identical but substantially identical, because of the specific configuration which may result in a height fluctuation between the different through holes 24, or a portion of the through holes 24 being slightly higher than the other air through holes 24, or the plurality of through holes 24 being slightly inclined as a whole, both of which and configurations which are not described in detail are within the scope of the present application. The through hole 24 is in fluid communication with the storage space 11. The purpose of the pressure equalizing cavity 2 is to make the forces on the surface of the liquid in the recovery tank 10 substantially the same, so that splash and splash caused by the disturbance of the air flow can not be caused, and the volume utilization rate of the recovery tank 10 can be effectively improved. Because the pressure near the air outlet channel 14 is the lowest and the suction force is the greatest when the pressure equalizing cavity 2 is not provided, uneven pressure distribution in the recovery tank 10 can be caused, so that disturbance is caused to liquid in the recovery tank 10, and water bloom is generated.
With continued reference to fig. 6-9, the recovery tank 10 also includes a float 16 therein, the float 16 including an open position and a closed position in which a portion of the float 16 extends into the equalization chamber 2 for shutting off air flow between the air flow inlet and the air flow outlet 23. In one embodiment, a float 16 is provided at the outlet channel 14, which moves with the liquid level in the recovery tank 10, and when the liquid level rises to a certain extent, part of the float 16 enters the equalizing chamber 2, shutting off the channel between the air flow inlet and the air flow outlet 23.
Referring to fig. 5-9, in one embodiment, the top end of the recovery tank 10 is provided with an opening, a cover 25 for sealing the opening is provided at the opening, a pressure equalizing plate 26 is provided at the inner side of the cover 25, and a pressure equalizing cavity 2 is defined between the pressure equalizing plate 26 and the cover 25. The periphery of the equalizing plate 26 is connected with the cover body 25 in a sealing way. The pressure equalizing chamber 2 can move together with the cover 25. In other embodiments, the recycling bin 10 may not have the cover 25, and the air inlet channel 12 and the air outlet channel 14 may be detachably mounted on the body of the recycling bin 10, where the body may be separately provided with a drain hole. The equalizing cavity 2 is defined by a top wall and an equalizing plate 26 which are oppositely arranged, a plurality of through holes 24 are formed in the equalizing plate 26, the peripheries of the through holes 24 extend outwards to form annular protrusions 28, and the annular protrusions 28 are higher than the outer wall 27 of the equalizing plate 26. The top wall may be a part of the main body 1 of the recovery tank 10, and may be a structure independent from the main body 1. The annular projection 28 serves to prevent droplets formed on the outer wall 27 of the equalizing plate 26 from being sucked into the through-hole 24.
Referring to fig. 15-17, fig. 15 is a schematic structural diagram of a pressure equalizing plate in an embodiment. Fig. 16 is a schematic view of the structure of the equalizing plate under another angle. Fig. 17 is an enlarged view of the structure of the region I shown in fig. 16. As shown in fig. 15-17, based on any of the above embodiments, the air inlet and air outlet 23 are provided in the equalizing plate 26. Of course, in other embodiments, the gas flow outlet 23 may not be provided on the equalizing plate 26, but need only be in fluid communication with the equalizing chamber 2.
Referring to fig. 16-17, based on any of the above embodiments, the outer wall 27 of the pressure equalizing plate 26 is further provided with a plurality of outwardly extending liquid collecting structures 29, the liquid collecting structures 29 being arranged around the annular protrusion 28. The purpose of the liquid collecting structure 29 is to collect the water film formed by the outer wall 27 of the pressure equalizing plate 26 into small droplets, which fall into the storage space 11. The liquid-collecting structure 29 is generally referred to as a cone,
referring to fig. 12, and also referring to fig. 15-17, based on any of the above embodiments, the pressure equalizing chamber 2 includes a distribution chamber 21 and a convergence chamber 22, where the convergence chamber 22 is generally disposed adjacent to the outlet inlet 15 of the outlet pipe, so as to ensure that the air flow passing through per unit time meets the requirements of the surface cleaning apparatus. The distribution chamber 21 is generally disposed directly above the liquid, preferably over all surfaces of the liquid, although the distribution chamber 21 may not cover all surfaces of the liquid, depending on the specific structure. The plurality of through holes 24 are uniformly distributed in the distribution chamber 21. To ensure that the pressure generated at the through-holes 24 is substantially the same. The height H1 of the distribution chamber 21 in the vertical direction is smaller than the height H2 of the convergence chamber 22. The bottom area of the converging chamber 22 is smaller than 1/5 of the bottom area of the distribution chamber 21, so that the bottom area of the distribution chamber 21 can be made as large as possible to cover a relatively large liquid surface. To enhance the pressure equalizing effect, the total area of the plurality of through holes 24 is less than 1/5 of the area of the equalizing plate 26. Further, the total area of the through holes 24 is less than 1/10 of the area of the equalizing plate 26. Further, the total area of the through holes 24 is less than 1/20 of the area of the equalizing plate 26.
Referring to fig. 18-22, fig. 18 is a schematic structural diagram of a gas-liquid separation device according to an embodiment.

The gas-liquid separation device 3 includes a housing 31 and a gas-liquid separation portion 32 provided in the housing 31. The hood 31 defines a buffer cavity 38 facing the air inlet outlet 13. The gas-liquid separation portion 32 is disposed on the cover 31, the gas-liquid separation portion 32 extends substantially in a horizontal direction, the gas-liquid separation portion 32 includes a plurality of guide plates 33 disposed at intervals, wherein the guide plates 33 extend in a direction away from the cover 31, and air outlet holes 39 are defined between adjacent guide plates 33. The guide plate 33 is used for guiding the air flow blown out from the air inlet outlet 13 to flow along the horizontal direction, so that the air flow is prevented from being directly blown to the equalizing plate 26 or blown to the liquid level, if the air flow is directly blown to the liquid level, a great amount of water spray can be excited if the air inlet outlet 13 is relatively short from the liquid level, and if the air flow directly blows to the equalizing plate 26, water vapor in the air flow can enter the equalizing cavity 2. Therefore, the guide plates 33 are arranged substantially horizontally, and the air outlet holes 39 are provided between the guide plates 33, so that the movement distance of the air flow in the recovery tank 10 is increased, and the gas-liquid separation effect is improved.
The guide plate 33 is provided with a guide groove 34, the opening of the guide groove 34 facing downward and being in fluid communication with the buffer cavity 38 of the housing 31.
