The threaded slider 15 is slidably arranged in the sliding grooves 24, and the upper and lower parts of the partition plate 16 are provided with connecting chambers 18. The ends of the two sliding plates 20 close to each other and located in the direction of the external air duct 11 are fixed with a receiving plate 21, and a scraper 22 is fixed at the upper end of the receiving plate 21. A filter is provided at the receiving plate 21 at the lower end. The two receiving plates 21 are connected to the opening and closing doors at the ends close to the external air duct 11 through a torsion spring hinge rod. The left end surface of the shell 10 is connected with an openable door panel 19, and a handle is provided on the door panel 19. The scraper 22 is tightly attached to the heat exchange plate 17 and the partition plate 16, and the upper end is set in a triangular tip. A temperature sensor is provided at the heat exchange chamber 23 on the right side and is connected to the control end, and the control end is electrically connected to the power motor 13;

[0020] Under normal working conditions, cold air from the outside enters the outer air duct 11 through the air inlet pipe, and the cold air fills the heat exchange chamber 23 on the left. It is blocked by the partition plate 16 and the sliding plate 20, and the cold air is discharged from the outer air duct 11 at the other end. Similarly, the hot air in the cabinet is drawn into the heat exchange chamber 23 on the right by the inner air duct 12, and is also blocked by the partition plate 16 and the sliding plate 20. In the left and right heat exchange chambers 23, heat exchange is performed by the heat exchange plate 17 on the partition plate 16, thereby reducing the temperature of the hot air discharged from the inner air duct 12.

The scraped dust is concentrated and collected on the storage plate 21. The movement of the partition plate 16 stops after the two scrapers 22 abut against each other. At this time, the inner air ducts 12 adjacent to the outer air duct 11 are connected to the heat exchange cavity 23 through the partition plate 16. The outer air ducts 11 and the inner air ducts 12 adjacent to each other on the left and right draw the hot air inside the cabinet and discharge it outward, and the outer air duct 11 and the inner air duct 12 at the other end draw the cold air outside the cabinet and fill it inward;

[0021] The user opens the door panel 19 and the opening and closing door on the storage plate 21 to take out the collected dust from between the two storage plates 21. During use, the filter screen at the lower end of the storage plate 21 is used to reduce the influence of air flow on the dust collected in the storage plate 21.
