Description

Air bag type push switch for pneumatic control drain valve Technical Field The utility model relates to the technical field of push switches, in particular to an air bag type push switch for a pneumatic control drain valve. Background Pneumatic control drain valves (or pneumatic drain valves) are key components widely used in modern water-saving sanitary appliances. The operating principle is that a push switch on the water tank cover is operated, and the switch is connected with a drain valve body at the bottom of the water tank through a pneumatic control pipeline. When a user presses the switch, a mechanism in the switch can compress air in the pipeline, and the opening and closing of the drain valve are triggered by air pressure transmission, so that the water draining or stopping function is realized. However, since the air bag has elasticity, the air bag is contracted due to more pressing times, so that the air outlet amount is shortened. Disclosure of utility model The utility model aims to provide an air bag type push switch for a pneumatic control drain valve, which aims to solve the problems in the prior art. The air bag type pressing switch for the pneumatic control drain valve comprises a base, an air bag component and a pressing seat, wherein a cavity is formed in the base, a spring is axially arranged in the cavity, the air bag component stretches into the spring and can be axially compressed, the pressing seat is detachably and fixedly connected with the base, and the air bag component is pressed by the pressing seat to generate air pressure change so as to control the pneumatic control drain valve. Preferably, an upper connecting groove which is matched and connected with the air bag component is arranged in the cavity. Preferably, the airbag module includes: The air bag is an elastic air bag, an upper convex column is arranged at the top of the air bag, a lower convex column is arranged at the bottom of the air bag, a sealing ring is sleeved on the upper convex column, and the top of the air bag extends into the upper connecting groove through the upper convex column and is fixed in the upper connecting groove by extruding the sealing ring; The bottom of the connecting seat is provided with at least two driving rods, the driving rods are in one-to-one correspondence with the pressing blocks, the connecting seat is provided with at least one through hole, the top of the connecting seat is provided with a lower connecting groove, and the bottom of the air bag is fixed in the lower connecting groove through a lower convex column; The connecting sleeve is characterized in that the air bag stretches into the connecting sleeve and is fixedly installed inside the connecting sleeve, at least one inserting plate is arranged on the connecting sleeve, an opening is formed in the bottom of the inserting plate in an upward extending mode, support legs are formed on two sides of the opening, extension blocks are arranged at the bottom ends of the support legs, the two support legs can penetrate through the through holes in an extrusion mode in opposite directions, and the support legs are used for limiting the upward displacement of the connecting sleeve relative to the connecting seat through the extension blocks after reset. Preferably, the connecting seat is provided with at least two convex blocks, the cavity is correspondingly provided with a groove, and the connecting seat extends into the groove through the convex blocks, so that the connecting seat can stably press the air bag. Preferably, one of the driving rods is located right below the air bag, and the compression amount of the driving rod located right below the air bag to the air bag is larger than that of the other driving rods to the air bag. Compared with the prior art, the utility model has the beneficial effects that: 1.
