During implementation, the dust blocking part 3 is arranged above the sleeving groove 4, and the dust blocking part 3 is pressed downwards so as to be embedded into the sleeving groove 4, so that the dust blocking part 3 is assembled. Therefore, in the assembling process of the dust blocking part 3, the outer wall surface of the connecting piece can guide the dust blocking part 3, so that the dust blocking part can be assembled smoothly, and the assembly does not adopt a fastening piece, so that the dust blocking part 3 is convenient to disassemble; in addition, the outer wall surface of the connecting piece can also carry out radial spacing on the dust blocking part 3, and the shaking of the dust blocking part 3 in the working process is reduced.

As for the structure of the connecting piece, in particular, the connecting piece comprises a plurality of blocks 5, the blocks 5 are arranged along the circumferential direction of the inner pipe 2 of the dust cup to form an annular connecting piece, and a gap is arranged between two adjacent blocks 5.

Considering that only a part of the outer wall surface of the baffle 5 is fixedly connected with the inner wall surface of the dust cup inner tube 2 in order to form the socket groove 4, the connection area between the two is small, and in order to improve the connection stability between the two, the dust cup further comprises a connecting rib 6, the connecting rib 6 is respectively and fixedly connected with the baffle 5 and the inner wall surface of the dust cup inner tube 2, exemplarily, the top end of the connecting rib 6 is fixedly connected with the baffle 5, and the side surface of the connecting rib 6 is fixedly connected with the inner wall surface of the dust cup inner tube 2.

Thus, through the dust blocking part 3 arranged separately, when the dust cup is in an assembly state (namely the fluid pipeline 8 is inserted into the dust cup inner pipe 2), under the action of the fluid pipeline 8, the suspended end of the dust blocking sheet is bent from the top end of the dust cup inner pipe 2 to the bottom end of the dust cup inner pipe 2, and the dust blocking part 3 is in an open position, so that the circulation of fluid in the fluid pipeline 8 is realized; when the dust cup is in a disassembly state (namely, the dust cup inner tube 2 is separated from the fluid pipeline 8), the plurality of dust blocking sheets form a complete continuous surface, the dust blocking part 3 is in a closed position to block the dust cup inner tube 2, and therefore the situation that dust leaks to the outer side of the dust cup through the dust cup inner tube 2 in the dust cup cleaning process can be avoided.

In order to facilitate the insertion of the fluid conduit 8, the dust-blocking portion 3 is tapered, and the tip of the taper is directed toward the bottom end of the inner tube 2 of the dust cup. Thus, when the fluid line 8 is inserted from the top end of the inner tube 2 of the dust cup, the dust guard 3 can be smoothly separated and switched from the closed position to the open position.

In this way, the dust blocking section 33 mainly plays a role of blocking dust, the bending sections 32 are narrow, and a gap (i.e., a hollow area) is formed between every two adjacent bending sections 32, so that bending is facilitated.

In order to facilitate the bending of the dust-blocking sheet, the position of the bending section 32 may correspond to the gap position of the stopper 5, so that when the bending section 32 is bent, the gap can provide a larger bending space for the bending section 32, thereby facilitating the bending of the dust-blocking sheet.
