[0042] The following points are worth noting:

[0043] 1. The heat conducting plate 4 is arranged outside the purification box 1, and can sense and absorb the temperature of the external air. The absorbed temperature is transmitted to the memory alloy rod 21, so that the memory alloy rod 21 gradually extends when absorbing heat, and can be automatically regulated according to the temperature change.

[0044] 2.

When air purification is performed, the heat conducting plate 4 will first sense and absorb the temperature in the external air, and the absorbed temperature will be transmitted to the memory alloy rod 21, so that the memory alloy rod 21 gradually extends when absorbing heat, and can be automatically regulated according to temperature changes. The extension of the memory alloy rod 21 will drive the moving rod 25 to move outward through the fixed rod 29, and push the driven rod 27 to move inward under the action of the flow of the arc tube 26 and the flowing liquid 28, and drive the blocking plate 19 to move inward to make it leave the air guide opening 18 to make it connected, and realize the replacement of internal and external air and the complementation of indoor and outdoor temperatures during the air flow through the air guide opening 18, the ventilation box 3, and the ventilation pipe 7.
