In this embodiment, the ratio of the height of the tub 21 to the height of the box 5 is equal to 3: 4.

The fluid conduit 3 is located within the tank 5 and has one end in communication with the fluid inlet 101 and the other end in communication with the fluid inlet 201 to conduct all of the dusty fluid entering the recovery vessel into the drum 21.

The pipe wall of the fluid pipeline 3 is tightly attached to the cavity wall (namely the inner wall of the box body 5) of the recovery containing cavity 1 as much as possible, so that the fluid pipeline 3 is prevented from occupying the volume of the recovery containing cavity 1 in a criss-cross manner, 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 body 5, the fluid pipeline 3 includes a first elbow 31, a second elbow 32, a longitudinal pipe 33 and a transverse pipe 34 which are connected in sequence, the first elbow 31 is connected with the fluid inlet 101, the longitudinal pipe 33 can be attached to the side wall of the recovery cavity through two bending transitions of the first elbow 31 and the second elbow 32, the transverse pipe 34 is vertically connected with the longitudinal pipe 33, and the outlet end of the transverse pipe 34 is connected with the liquid inlet 201.

The first bend 31 and the second bend 32 are connected together to form an "S" shape, so as to achieve the purpose of making the longitudinal pipe 33 tightly attached to the sidewall of the recycling cavity 1 (i.e. the inner sidewall of the box 5). Specifically, the first elbow 31 and the second elbow 32 are both arc pipes having one curvature, the arc of the first elbow 31 faces the cavity wall of the recovery accommodating cavity 1 adjacent to the first elbow, and the arc of the second elbow 32 faces the inner space of the recovery accommodating cavity 1.

In some embodiments, the first bend 31 and the second bend 32 may be combined into a bent tube having two bends, as long as it enables the longitudinal tube 33 to be attached to the side wall of the recovery volume, but such a bent tube is expensive to produce and difficult to assemble.

According to the fluid pipeline 3, the first bent pipe 31 and the second bent pipe 32 enable the longitudinal pipe 33 to be attached to the side wall of the recovery containing cavity 1, so that the volume of the recovery containing cavity 1 can be effectively saved, the situation that pipelines in the recovery containing cavity 1 are criss-cross is avoided, and the recovery container is convenient to clean; in addition, the sectional design of the fluid pipeline 3 also enables the assembly to be more convenient and reduces the production cost; then, the first elbow 31 and the second elbow 32 make a part of the fluid pipeline 3 be a bent pipeline, so as to slow down the flow rate of the dust-containing fluid in the fluid pipeline 3, further prolong the flow time of the dust-containing fluid in the fluid pipeline 3, so as to increase the filtering time of the filtering barrel for the dust-containing fluid entering the barrel body 1, and avoid the dust-containing fluid from flooding into the barrel body 1 in a large amount in a short time, so as to cause the filtering pressure of the filtering barrel to be too large, so as to ensure that the filtering barrel has a stable and good filtering effect.

In this embodiment, the upper end cap 4 is flush with the outer side wall of the box 5 so that the recycling container can be transferred.

In order to facilitate taking and moving the recovery container, the recovery container further comprises a handle 6, specifically, the handle 6 is located on the outer side of the box body 5, and the handle 6 and the key of the pressing piece 44 are located on the same side of the recovery container.
