The present application provides a kind of pressure water faucet, including valve body, valve core, first sealing member and push rod, valve body includes water inlet pipe part and water outlet pipe part, the present application is by setting first stop portion in water inlet pipe part, and first sealing member is set on the stop portion of valve core, and drive portion is at least partially extended to water outlet pipe part by passing through first stop portion, and setting convex part on push rod drive drive portion, make valve core move between initial position and drainage position, realize the switch of faucet, when valve core is in initial position, because water source gives the force of stop portion to the direction of drive portion, so that stop portion always has the tendency of moving to the direction of first stop portion and tightly extrude first sealing member between stop portion and first stop portion, so that water faucet can withstand larger water pressure, and with the increase of water pressure, the force of stop portion tends to first stop portion will increase synchronously, so that first sealing member is more tightly sealed between stop portion and first stop portion.

The utility model provides a kind of air path switch and the heat exchange device of application, air path switch includes: installation cylinder, the first air outlet and second air outlet of the installation cylinder are sequentially provided with for air flow to blow out the installation cylinder along circumference, and wind wall that blocks air flow to blow out the installation cylinder;Rotary assembly is located in the installation cylinder, and rotates around the center axis of the installation cylinder, and the rotary assembly is equipped with shielding part;Driving assembly is used to drive the rotary assembly to rotate in the installation cylinder, to make the shielding part move between the first air outlet, the second air outlet, the wind wall.
