[0040] The rack 402 is fixed on the top of the filter screen 2 and extends to the outer wall of the cooling box 1, and the rack 402 is meshed with the outer wall of the gear 401;

[0041] The cooling unit includes a rotating shaft 403, a first rotating wheel 404, a transmission rod 405, a second rotating wheel 406, a third rotating wheel 407, blades 408, and a movable block 409;
