[0016] Reference is made to FIG. 1 to FIG. 3.

[0017] An embodiment of the present utility model discloses a fresh-air system for multi-level underground garages, comprising an outer frame 1, wherein an air inlet chamber 100 and an air outlet chamber 101 are disposed in parallel in the outer frame 1; an air intake system 2 is disposed at an opening of the air inlet chamber 100; a plurality of air outlets 102 in communication with the air inlet chamber 100 are formed in parallel through one side of the outer frame 1; a movable door 3 is hinged to each air outlet 102 through a torsion spring; the air inlet chamber 100 comprises a transverse passage 103 and a longitudinal passage 104 in communication with each other; a slider 4 matching the longitudinal passage 104 in shape is disposed on the longitudinal passage 104; the slider 4 is in sliding connection with the longitudinal passage 104; a flow passage 40 is formed through the slider 4; the flow passage 40 comprises a flow passage inlet 400 disposed at the top of the slider 4 and a flow passage outlet 401 disposed on one side surface of the slider 4; a groove 41 is formed in one side of the slider 4; an ejector rod 5 is disposed in the groove 41; a spring 6 is fixedly connected between the ejector rod 5 and the groove 41; one end of the ejector rod 5 abuts against one side wall of the air inlet chamber 100 under the elastic force of the spring 6; a motor 7 is disposed at the bottom of the outer frame 1; the slider 4 is in lead screw connection with the motor 7; the slider 4 moves up and down along the longitudinal passage 104 under the driving of the motor 7; a plurality of air outlet mesh plates 8 arranged in parallel are fixedly connected to one side of the outer frame 1; and a plurality of air outlet holes 80 in communication with the air outlet chamber 101 are formed through the air outlet mesh plates 8.

[0018] In specific use, the outer frame 1 is disposed on a wall body of the underground garage, the air intake system 2 is in communication with the outdoors, and the air outlets 102 are in communication with garages on different floors respectively. When the air intake system 2 works, outdoor air is delivered into the air inlet chamber 100, and the motor 7 drives the slider 4 to move up and down along the longitudinal passage 104. When the slider 4 moves to the front side of a movable door 3, the ejector rod 5 pushes the movable door 3 open under the elastic force of the spring 6, and the air in the air inlet chamber 100 flows from the air outlet 102 through the flow passage 40 into a certain garage floor. Since only one movable door 3 is pushed open at the same time, the air delivered from the air outlet 102 can be ensured to have a relatively high wind speed; and by cyclically driving the slider 4 to move up and down along the longitudinal passage 104, air can be cyclically supplied to the garages on all floors. The system is simple in structure, can achieve a high-wind-speed air outlet effect without using a high-power air intake system, and effectively saves energy.
