Example 1: an exhaust assembly, as described in connection with fig. 1 and 3, comprising: the connecting part 1, connecting part 1 is connected with the disk seat 21 of the spot pressure type pneumatic valve 2, is used for carrying out fixed position to connecting part 1, makes things convenient for the later stage to last to exhaust, is provided with trigger part 3 on the case 22 of spot pressure type pneumatic valve 2, trigger part 3's cross section is non-circular, has seted up non-circular hole 11 on connecting part 1, and non-circular hole 11 cooperates with trigger part 3 and realizes the exhaust, so sets up, when non-circular hole 11 takes place the dislocation with trigger part 3, connecting part 1 can extrude trigger part 3 on case 22, and then spot pressure type pneumatic valve 2 is opened, and non-overlapping area is fluid medium exhaust passageway 5, and non-overlapping area can realize the change and realize the adjustability because of non-circular hole 11 realizes changing and then fluid medium's discharge flow, and simultaneously connecting part 1 is connected with the disk seat 21 of spot pressure type pneumatic valve 2 has realized liberating the technical problem that the single hand continuously presses case 22, has improved the convenience.

The click-pressure type air valve 2 includes: the valve seat 21 is a pipe body with one end open and the other end closed, a through hole is formed in the center of the bottom of the valve seat 21, a plurality of vent holes are circumferentially arrayed around the through hole, the valve core 22 is arranged in the through hole, the sealing disc 23 used for sealing the vent holes is arranged at the lower end of the valve core 22, the baffle ring 24 and the return spring 25 are arranged on the valve core 22, the return spring 25 is located between the baffle ring 24 and the valve seat 21, the specific structure of the point-pressure type air valve 2 is described above, and the point-pressure type air valve 2 is not limited to the specific structure.

The triggering part 3 and the valve core 22 are integrally formed or the triggering part 3 and the valve core 22 are detachably connected, the detachable connection can be implemented under the condition of not damaging the appearance of the valve core 22, for example, the detachable connection is realized through bolt connection, the cost is low, the process is simple, and the detachable connection is suitable for mass production.
