[0027] Among them, Figure 3 As shown, the fixed shell 13 is provided with a sliding groove that matches the sealing plate 2. The sealing plate 2 forms a sliding structure with the fixed shell 13 through the fixed frame 3, which is conducive to the sealing plate 2 being able to fit the clean door to achieve a sealing effect and prevent debris and dust from falling into the fixed shell 13.

[0028] Among them, Figure 3 As shown, the limiting column 6 is provided with a sliding groove that matches the sliding column 5. The sliding column 5 forms a sliding structure with the limiting column 6 through the fixed frame 3, which is conducive to the sliding column 5 shrinking into the groove of the limiting column 6 to move the sealing plate 2 downward.

[0029] Among them, Figure 3 As shown, the hollow column 12 is provided with a sliding groove that matches the telescopic column 10. The telescopic column 10 forms a buffer structure with the hollow column 12 through the fixed frame 3 and the spring 11, which is conducive to the telescopic column 10 sliding in the groove of the hollow column 12, relying on the spring 11 to play the role of elastic support.

[0030] Among them, Figure 3 As shown, two groups of sealing plates 2, fixed frames 3, rotating shafts 4, sliding columns 5, limiting columns 6, rotating columns 7, rotating shafts 8, fixed plates 9, telescopic columns 10, springs 11, hollow columns 12 and fixed shells 13 are provided.

[0033] Among them, Figure 4 As shown, two groups of connecting plates 14 and sealing strips 15 are provided, and the positions of the two groups of connecting plates 14 and sealing strips 15 are symmetrically distributed about the midpoint of the fixed shell 13, which is beneficial to prevent air leakage from the left and right sides of the clean door.

[0034] During use: by closing the clean door, the sealing plate 2 is brought into contact with the clean door, and the sealing plate 2 will shrink along the slope to slide inside the fixed shell 13, driving the fixed frame 3 to move downward, so that the sliding column 5 shrinks back into the groove of the limit column 6. At the same time, the fixed frame 3 will drive the telescopic column 10 to slide in the groove of the hollow column 12, and the spring 11 will play the role of elastic support, so that the sealing plate 2 can seal the upper and lower ends of the clean door to prevent air leakage. At the same time, the outer wall of the sealing plate 2 slides against the inner wall of the fixed shell 13, which can also prevent debris from falling into the fixed shell 13, avoiding frequent disassembly and cleaning. The sealing strip 15 seals the left and right sides of the clean door, with a simple structure and practical performance.
