The blocking structure 200 includes a blocking plate 201 adapted to engage with the cleaning port 102, and a plurality of positioning rods 202 fixedly connected to the side of the blocking plate 201. The plurality of positioning rods 202 are respectively adapted to engage with a plurality of positioning sleeves 103. Through the engagement of the positioning rods 202 and the positioning sleeves 103, the blocking plate 201 can be initially fixed on the housing 101, thereby realizing rapid positioning.

[0032] A fixing structure 300, the fixing structure 300 is fixedly connected to a side of the positioning sleeve 103 away from the housing 101, and the fixing structure 300 is used to fix the positioning rod 202 and the positioning sleeve 103 together;

[0033] The limiting structure 400 is connected to the fixed structure 300 and is used to limit the fixed structure 300 .

[0034] Specifically, Figure 3 A rubber pad 203 is provided between the sealing plate 201 and the shell 101. The rubber pad 203 is fixedly connected to the sealing plate 201 and movably abuts against the shell 101. The rubber pad 203 is provided to improve the sealing between the sealing plate 201 and the shell 101, and air leakage is less likely to occur.
