Fluid control device and pneumatic comfort system

Abstract

The present application relates to the technical field of valve bodies, and especially to a fluid control device and a pneumatic comfort system. The fluid control device comprises a valve body, a valve core, a coil and a medium flow channel, wherein the valve body is provided with a communication chamber, and a first medium opening, a second medium opening and a third medium opening, which are in communication with the communication chamber; the valve core is arranged in the communication chamber; the coil is arranged on the valve body, and is configured to, upon energization, actuate the valve core to move so as to close or open the first medium opening; and the medium flow channel brings the second medium opening into communication with the third medium opening. The fluid control device has a first air-passing state and a second air-passing state. In the first air-passing state, the valve core closes the third medium opening, and the first medium opening is open and is in fluid communication with the second medium opening by means of the communication chamber. In the second air-passing state, the valve core opens the third medium opening, and the first medium opening is closed, and the third medium opening is in fluid communication with the second medium opening at least through the medium flow channel. In this way, the present application can achieve all of rapid inflation, rapid deflation and the passage of air.
