[0032] The left end of the winding box 2 is also provided with a dust extraction component 4 used in conjunction with the cleaning component 22. The dust extraction component 4 includes a fixed frame 5 fixedly arranged at the left end of the winding box 2. The left wall of the winding box 2 is evenly provided with air vents 18, and an exhaust fan 19 is arranged in the fixed frame 5. When dust enters the winding box 2, the exhaust fan 19 is started to generate negative pressure in the winding box 2, and the dust floating in the winding box 2 can be discharged through the air vent 18 under the suction of the exhaust fan 19, thereby helping to prevent the dust from falling on the curtain body 8 again. Compared with the prior art, the technical problem that the dust falling on the curtain body 8 still affects the cleanliness of the curtain is solved.

[0033] Furthermore, an iron column 9 is horizontally fixed at the bottom of the curtain body 8. By horizontally setting the iron column 9, it is possible to directly observe whether the curtain body 8 is in a horizontal state through a viewing angle, thereby avoiding the situation where the curtain body 8 is offset when it is rolled up.

[0034] Furthermore, two magnets 10 are symmetrically arranged on the mounting plate 1, and the iron column 9 can be adsorbed on the two magnets 10. The magnets 10 adsorb the iron column 9, and the unrolled curtain body 8 is tightened.

[0035] The above-mentioned implementation modes are only preferred implementation modes of the present application and cannot be used to limit the scope of protection of the present application. Any non-substantial changes and substitutions made by technicians in this field on the basis of the present application shall fall within the scope of protection required by the present application.
