    The outer end of the core 420 of the intake valve is connected to a seal 440 of the intake valve, the outer end of the through hole 411 is provided with an annular chamfer 415, the size and the shape of chamfer 415 is compatible with those of seal 440, and the spring is used to seal through hole 411 as soon as seal 440 contacts annular chamfer 415 closely. The outer end of through-hole 411 faces toward cavity 104 of valve 1, and the inner exterior of through-hole 411 faces outward from valve 1. In this example, like regular gaskets, this gasket The sealed intake valve is also made of plastic.
    The inner end of the through hole 411 of the intake valve is connected to a cover 5, the cover 5 being intended to prevent air leakage.
    The through hole 311 of the purge valve is coaxial with the through hole 411 of the intake valve; There should be clearance between the purge valve cover 322 and the inlet valve seal 440. When the inlet valve core 420 is pressed from the through hole 411 of the inlet valve to the valve cavity, the inlet valve core 420 can push the core 320 outwardly. through the seal 440, so as to open the outlet orifice.
    The valve 1 is composed of a housing 105 and a side cover 106, the outlet orifice 102 is provided on the housing 105, and the inlet orifice 101 is located on the side cover 106.

This is favorable to the positioning of the two bodies.
    The product after the improvement: The inner side of the seal 340 of the purge valve has an extension 341, this elastic extension 341, the part on the extension 341 far from the seal 340 is the distal part of the extension 341, it is provided with a projection 342 radial outwards, after having penetrated the internal hole 323 of the core 320 of the purge valve, the projection moves to the inside of the bore 324 of the core for the purge valve, and the protrusion 342 should be larger than the inner hole 323 of the core 320 of the purge valve. This structure favors the connection of the seal of the purge valve and the core, which facilitates rapid assembly and disassembly.
    The inner side of the seal 440 of the intake valve has an extension 441, this extension 441 is elastic, the part on the extension 441 far from the seal 440 is the distal part of the extension 441 , it is provided with a radial projection 442 towards the outside, after having penetrated the internal hole 423 of the core 420 of the intake valve, the projection moves to the inside of the bore 424 of the core to intake valve, and the protrusion 442 should be larger than the inner hole 423 of the intake valve core 420. This structure promotes the connection of the seal and the inlet valve core, which facilitates rapid assembly and disassembly.
    The air bag 2 is located near the valve 1, and the air bag 2 is located on the central axis of the outlet orifice 102 and near the central axis of the inlet orifice 101.
    Figures 7 and 8 are the diagrams describing the state of inflation. Object 9 must be inflated. In use, the main body of the purge valve 310 is connected to the inflatable object 9 in a sealed manner.
    During inflation, we can open the cover 5, compress the air bag 2, the pressure inside the cavity 104 will be increased, under the influence of the pressure, and the seal 440 of the valve d 'inlet tightens strongly against the annular chamfer 415, so as to maintain the closure of the inlet port 101; The pressure acts on the fixed cover 322 for the purge valve spring, the core 320 of the purge valve compensates for the elasticity of the spring 330 of the purge valve, and in this way a clearance occurs between the gasket. sealed 340 of the purge valve and the annular chamfer 315, the air in the air bag 2 is transmitted to the object to be inflated via the air chamber 103, and the cavity 104 and the outlet 102 through this clearance. When the air bag 2 is released, the air bag 2 will be expanded, and in this case the bag generates negative pressure, the airtight seal 340 of the purge valve presses against the annular chamfer 315, the outlet 102 is closed; Influences by the external pressure, and the inlet valve core 320 compensates for the elasticity of the inlet valve spring 430 by moving towards the bleed valve core 320, and at that time a clearance occurs between the airtight seal 440 of the inlet valve and the annular chamfer 415, the outside air enters the cavity 104 from the inlet port 101, then accesses the acrien2 bag through the chamber to air 103, until the air sac 2 can be expanded to normal. Compress the airbag 2 again, the object will be inflated. Repeat this several times. This inflator is compact, simple in structure, easy to operate and easy manual operation.
    During the exhaust, press the fixed cover 422 of the spring of the intake valve, the core of the intake valve will compensate for the elasticity of the spring 430 by moving towards the core of the purge valve 320, and in this case a clearance occurs between the inlet valve seal 440 and the annular chamfer 415, the inlet valve seal 440 will push the fixed valve spring cover 322 bleed valve, so that the core 320 compensates for the elasticity of the spring 330 of the bleed valve by moving outward, a clearance thus occurs between the seal 340 and the annular chamfer 315, and the air in it. the object will be escaped through the exit and entry ports. The exhaust is easy to do manually, and easy to control manually. Pressure and exhaust can be adjusted easily.
    What proceeds are only examples suitable for this invention, and not to limit this invention, all modifications, replacements and improvements etc. in accordance with the principles of the present invention will be contained within the protective scope of this invention.
