By starting the motor 7, the valve plate 10 can reciprocate inside the base 2, so that the air pressure inside the base 2 changes, so that air flow can be generated from the connecting tube 9 and discharged from the air outlet pipe 14, so that the components placed inside the box body 1 can be evenly cooled, thereby improving the heat dissipation effect inside the box body 1.

[0026] Please refer to Figure 3 , Figure 4 and Figure 5 As shown, the diameter of the hole at the position of the inner cavity of the air intake pipe 4 close to the side of the casing 1 is larger than the diameter of the hole at the position away from the side of the casing 1, a sealing plug 16 is movably arranged inside the air intake pipe 4, and a fixing rod 17 is inserted through the surfaces of the upper and lower ends of the sealing plug 16, one side of the fixing rod 17 is fixed to the inner wall of the air intake pipe 4, and the diameter of the surface of one side of the sealing plug 16 is equal to the diameter of the hole at the side of the inner cavity of the air intake pipe 4 away from the casing 1, a filter screen 15 is fixed at the position of the inner cavity surface of the air intake pipe 4 away from the casing 1, the diameter of the surface of the outer peripheral surface of the fixing rod 17 close to the casing 1 is larger than the diameter of the surface of the side away from the casing 1, and a first spring 18 is sleeved on the outer peripheral surface of the fixing rod 17, and one side of the first spring 18 is fixed to the position of the fixing rod 17 at the adjacent position close to the side of the casing 1, and the first spring 18 The other side is fixed to the surface of the sealing plug 16, and when the valve plate 10 moves in the direction close to the sealing plug 16 at the adjacent position, one side of the sealing plug 16 can extend to the side of the inner cavity of the intake pipe 4 away from the casing 1 so that it can seal the intake pipe 4, thereby preventing the airflow generated when the valve plate 10 moves from the inside of the intake pipe 4 at the adjacent position from flowing out, and when the valve plate 10 moves in the direction away from the sealing plug 16 at the adjacent position, the sealing plug 16 can be separated from the position of the inner cavity of the intake pipe 4 away from the side of the casing 1 and contact the first spring 18 at the adjacent position to deform it, thereby allowing outside air to flow into the interior of the intake pipe 4, and when the valve plate 10 stops, the sealing plug 16 can seal the intake pipe 4 again under the rebound force of the first spring 18 at the adjacent position.
