The movable push plate 21 and the sealing push plate 22 are driven to move, and the movable push plate 21 stretches the spring 23. When the contact push rod 25, the movable push plate 21 and the sealing push plate 22 move to the lowest end of the limit push groove 24, the contact push rod 25, the movable push plate 21 and the sealing push plate 22 move to the maximum distance, and the movable push plate 21 and the sealing push plate 22 can push away the dust between the roots of the blades 16, thereby avoiding dust accumulation here, which is inconvenient for users to clean. When the contact push rod 25, the movable push plate 21 and the sealing push plate 22 continue to rotate with the rotating rod 15, the contact push rod 25, the movable push plate 21 and the sealing push plate 22 are reset under the action of the spring 23's own resilience, so that the sealing push plate 22 is stuck between the blades 16 on both sides again.In order to facilitate the next cleaning work, the device can not only greatly improve the thermal insulation performance and corrosion resistance, but also heat to ensure the normal temperature inside the device while reducing heat loss, and also prevent the dust box 1 from directly contacting the outside world, thereby increasing its service life. At the same time, the device is also convenient for users to use, and there is no need to clean the roots of the blades 16, thereby avoiding dust accumulation and affecting normal use in the later stage.
