A second valve plate 134 is provided below the valve plate 13, a first spring plate 135 extending into the first circular hole 131 is provided on the upper surface of the valve plate 13, a second spring plate 136 extending into the second circular hole 132 is provided on the lower surface of the valve plate 13, first air holes 139 communicating with the first circular hole 131 and the second circular hole 132 are respectively provided on opposite sides of the valve plate 13, second air holes 1311 communicating with the two first air holes 139 are respectively provided on the upper and lower surfaces of the valve plate 13, and the two second air holes 1311 correspond to the cylinder head 11 and the cylinder seat 12 respectively.

[0024] Based on the above structure, during the specific implementation of this application:

[0025] When the motor compresses the air, the first valve plate 133 is closed, and the second valve plate 134 drives the second spring plate 136 to compress upward. When the second spring plate 136 compresses upward, the air intake of the first air hole 139 directly passes through the corresponding second air hole 1311 to the cylinder head 11, so that the gas enters the cylinder head 11;

[0026] When the motor inhales, the second valve plate 134 closes, and the first valve plate 133 drives the first spring plate 135 to compress downward; when compressing downward, the second air hole 1311 takes in air, and the air enters the cylinder head 11 through the second air hole 1311 directly.

[0028] In order to ensure that the vibration of the pump body is reduced and buffered, the present application also provides a base 17 under the motor pump head 10, and four springs 18 are provided at the bottom of the base 17. When the four springs 18 of the present application are implemented, they are to be installed on the air tank of the air compressor. The specific installation diagram will not be described in detail here.

[0029] In order to ensure the sealing of the first valve plate 13, the present application provides an O-ring 138 in the first circular hole 131 above the first valve plate 13, and the second circular hole 132 provides an O-ring 138 below the second valve plate 13.
