The exhaust passage is internally provided with a filter part 111, the filter part 111 is hermetically connected with the side wall of the exhaust passage, so that the dusty airflow entering the exhaust passage is discharged out of the recovery container after being dedusted and dehumidified by the filter part 111,

the filter 111 corresponds to the gas outlet 602 for filtering the dust-containing gas flow from the gas outlet 602 and discharging the filtered gas to the recovery container. Specifically, the filter portion 111 includes a filter hypaete and a desiccant to remove dust and water molecules in the dust-containing gas, so that the gas flow discharged from the recovery container is dry and clean, and corrosion of the downstream components of the recovery container is prevented.

In this embodiment, the filter portion 111 is detachably covered at the outlet of the passage, so as to facilitate installation, disassembly, cleaning and maintenance.

The upper end cover 11 is detachably connected with the box body 12, and a sealing ring 112 is arranged at the joint, the sealing ring 112 can enhance the connection strength of the upper end cover 11 and the box body 12, and the upper end cover 11 is hermetically connected with the box body 12, so that the air flow entering the recovery cavity can only be discharged through the exhaust passage.

In this embodiment, the bottom of the upper end cover 11 is provided with an assembly ring belt 113, the sealing ring 112 is sleeved outside the assembly ring belt 113, the shape of the assembly ring belt 113 is matched with the shape of the box body 12, the assembly ring belt 113 is sleeved with the sealing ring 112 and can be inserted into the box body 12, and the upper end cover 11 is in interference fit connection (or tight fit connection) with the box body 12 through the sealing ring 112, so that the side wall of the upper end cover 11 and the side wall of the box body 12 are in sealed connection.

Further, the outer side wall of the assembly ring belt 113 is provided with threads, and the inner side wall of the sealing ring 112 is provided with threads matched with the threads of the assembly ring belt 113, so as to enhance the connection performance between the upper end cover 11 and the box body 12. In addition, the outer side wall of the gasket 112 is provided with threads so that the upper end cover 11 can be detached from the case 12.

It should be noted that the assembly ring belt 113 is arranged around the outside of the connecting plate 62, so as to avoid the assembly ring belt 113 interfering with the assembly of the filter vat 6.

The upper cap 11 further includes a pressing member 114, and the recovery tank is detachably mounted in the floor cleaning apparatus through the pressing member 114. Specifically, the keys of the pressing piece 114 are located on the side wall of the upper cap 11.

The connecting plate 62 is connected with the upper end cover 11, the barrel body 61 is positioned in the box body 12, a gap is arranged between the side wall of the barrel body 61 and the side wall of the box body 12, and a gap is arranged between the bottom wall of the barrel body 61 and the bottom wall of the box body 12 to ensure the solid-liquid separation effect in the recovery container, and the gap between the side wall and the bottom wall is enough for the fluid pipeline 7 to pass through so as not to influence the circulation of dust-containing fluid in the fluid pipeline 7.

The ratio of the height of the barrel body 61 to the height of the box body 12 is more than or equal to 1:2 and less than or equal to 4:5, so that the recovery container has good solid-liquid separation effect and enough volume for storing waste liquid. In this embodiment, the ratio of the height of the tub 61 to the height of the case 12 is equal to 3: 4.

A fluid conduit 7 is located within the tank 12 and has one end in communication with the fluid inlet 101 and the other end in communication with the inlet 601 to conduct all of the dusty fluid entering the recovery vessel into the drum 61.

The pipe wall of the fluid pipeline 7 is tightly attached to the cavity wall of the recovery containing cavity (namely the inner wall of the box body 12) as much as possible, so that the fluid pipeline 7 is prevented from occupying the volume of the recovery containing cavity due to criss-cross arrangement in the recovery containing cavity, and further the volume of the barrel body 1 and the volume of the liquid storage space are compressed.

In this embodiment, the fluid inlet 101 is located on the bottom wall of the box 12, the fluid conduit 7 includes a first elbow 71, a second elbow 72, a longitudinal pipe 73 and a transverse pipe 74 which are connected in sequence, the first elbow 71 is connected with the fluid inlet 101, the longitudinal pipe 73 can be attached to the side wall of the recovery cavity through two bending transitions of the first elbow 71 and the second elbow 72, the transverse pipe 74 is vertically connected with the longitudinal pipe 73, and the outlet end of the transverse pipe 74 is connected with the fluid inlet 601.

The first bend 71 and the second bend 72 are joined together to form an "S" shape so that the longitudinal duct 73 abuts the side wall of the recovery volume (i.e. the inner side wall of the housing 12). Specifically, the first elbow 71 and the second elbow 72 are both arc pipes provided with one curvature, the arc of the first elbow 71 faces the wall of the recovery chamber adjacent thereto, and the arc of the second elbow 72 faces the inner space of the recovery chamber.

In some embodiments, first bend 71 and second bend 72 may be combined into a bent tube having two bends, so long as it enables longitudinal tube 73 to be placed against the side wall of the recovery volume, except for the relatively high cost and difficulty of assembly of such bent tubes.

According to the fluid pipeline 7, the first bent pipe 71 and the second bent pipe 72 enable the longitudinal pipe 73 to be attached to the side wall of the recovery containing cavity tightly, so that the volume of the recovery containing cavity can be effectively saved, pipelines in the recovery containing cavity are prevented from being criss-cross, and the recovery container is convenient to clean; in addition, the sectional design of the fluid pipeline 7 also enables the assembly to be more convenient and reduces the production cost; then, the first elbow 71 and the second elbow 72 make a part of the fluid pipeline 7 be a curved pipeline, so as to slow down the flow rate of the dust-containing fluid in the fluid pipeline 7, further prolong the flow time of the dust-containing fluid in the fluid pipeline 7, so as to increase the filtering time of the filtering barrel on the dust-containing fluid entering the barrel body 1, and avoid that the dust-containing fluid largely gushes into the barrel body 1 in a short time, so that the filtering pressure of the filtering barrel is too large, thereby ensuring that the filtering barrel has a stable and good filtering effect.

In this embodiment, the upper end cap 11 is flush with the outer side wall of the box 12 so that the recycling container can be transferred.

In order to facilitate picking and placing the mobile recovery container, the recovery container further comprises a handle 8, specifically, the handle 8 is located on the outer side of the box body 12, and the handle 8 and the key of the pressing piece 114 are located on the same side of the recovery container.

The above description is only for the preferred embodiment of the present invention, but the scope of the present invention is not limited thereto, and any changes or substitutions that can be easily conceived by those skilled in the art within the technical scope of the present invention are included in the scope of the present invention.
