It should be understood that in the present embodiment, the sealing portion 312 is located directly below the air outlet hole 15 and the first air passage 12, and when moving up, the edge portion of the sealing portion 312 contacts the transition portion 111 and seals the air outlet hole 15 and the first air passage 12. The sliding part 311 is perpendicular to the sealing part 312, and the lower end of the sliding part 311 is fixedly connected with the center of the sealing part 312. Preferably, the sliding portion 311 and the sealing portion 312 are formed as an integral structure, and are integrally formed during molding.

The positioning and supporting of the whole air nozzle structure 3 are realized by the sleeve 112, wherein the sliding part 311 can move up and down axially through the air passage relative to the sleeve 112. Because the return spring 35 is respectively abutted against the stem cap 34 and the sleeve 112, it can produce a lifting action on the whole air tap structure 3, so that the sealing part 312 is in sealing contact with the lower end face of the valve body 11, and when the stem cap 34 is pressed, the return spring 35 is further compressed, so that the sealing part 312 moves downwards to realize air leakage. Preferably, the stem cap 34 has an extension portion 341, the extension portion 341 is sleeved on the outer side of the sliding portion 311, and the return spring 35 is sleeved on the outer side of the extension portion 341.

The inflating part is combined with the inflating device, so that the inflating part is simple in structure and convenient to operate, and can meet the use requirements of users.

Preferably, to avoid inconvenience of pressing the plunger cap 34 all the time during pressure relief. The technical scheme also provides a pressing structure, which is shown in figures 10-12. Particularly, after the plunger cap 34 is pressed, the pressure relief state is kept, and the plunger cap is pressed again to realize sealing. Specifically, the sliding part 311 is further sleeved with a snap ring 4, the axial relative position of the snap ring 4 and the sleeve 112 is unchanged, the snap ring 4 can rotate around the axial lead of the sleeve 112, and n protrusions 41 are uniformly distributed on the inner side surface of the snap ring 4;

wherein the lower peripheral side of the core cap 34 has 2n first helical teeth 342, the peripheral side of the sliding portion 311 has 2n second helical teeth 3112 arranged opposite to the first helical teeth 342, the portion of the sliding portion 311 between the first helical teeth 342 and the second helical teeth 3112 forms a recess 3113 for the projection 41 to slide, the lower portion of the sliding portion 311 has n guide grooves 3114 evenly distributed in the axial direction and communicating with the recess 3113, the tip of the first helical teeth 342 faces the second tooth groove 3112, one of the guide grooves 3114 communicates with one of the second tooth grooves 31121; when the plunger cap 34 is pressed to move the sliding portion 311 downward in the axial direction by a predetermined stroke, the protrusion 41 slides out of the guide groove 3114, and when the sliding portion 311 moves downward by the return spring 35 after the external pressure is removed from the plunger cap 34, the protrusion 41 rotates by a predetermined angle and is locked to the second tooth groove 31121 of the second helical tooth 3112. Preferably, n is 1. In order to fix the snap ring 4, a snap ring 115 is disposed below the sleeve 112, the snap ring 115 is fixed to the lower end of the sleeve 112 and forms an annular snap groove (not shown) with the lower end surface of the sleeve 112, and the snap ring 4 is accommodated in the annular snap groove and can rotate in the annular snap groove.

Air leakage process: the sliding portion 311 is located at the highest end of its stroke range, i.e., the position closest to the sleeve 112, where the protrusion 41 is located in the guide groove 3114. When the plunger cap 34 is pressed, the whole sliding part 311 moves downwards relative to the sleeve 112, the guide groove 3114 is separated from the protrusion 41, the protrusion 41 contacts with the arc bevel edge of the first helical tooth 342 as the sliding part 311 moves downwards continuously, and the protrusion 41 rotates due to the constraint of the arc bevel edge of the first helical tooth 342 as the sliding part 311 moves downwards further until the protrusion 41 contacts with the first tooth socket at the first helical tooth 342, and at this time, the protrusion 41 faces the second tooth socket; then, the hand is released, and the slide portion 311 moves upward by the return spring 35, so that the protrusion 41 falls into the second tooth groove 31121 and gets caught. This is because the sliding portion 311 is finally moved down by a distance so that the sealing portion 312 is displaced to perform deflation and the deflated state can be maintained, so that it is not necessary to depress the sliding portion 311 long. When the plunger cap 34 is pressed again, the sliding portion 311 moves down, the protrusion 41 contacts with the circular arc inclined edge of the adjacent first oblique tooth 342, the snap ring 24 rotates by an angle under the circular arc inclined edge, the protrusion falls into the first tooth groove 3421, at this time, the hand is released, the sliding portion 311 moves up and returns under the action of the return spring 35, so that the protrusion 41 contacts with the circular arc inclined edge of the previous adjacent second oblique tooth 3112, and falls into the guide groove 3114 along the circular arc inclined edge under the action of the elastic force of the return spring 35, and thus the sealing of the sealing portion 312 is realized. The above process achieves a seal-deflate to seal process. And if the air needs to be deflated again, repeating the steps.

Variations and modifications to the above-described embodiments may occur to those skilled in the art, which fall within the scope and spirit of the above description. Therefore, the present invention is not limited to the specific embodiments disclosed and described above, and some modifications and variations of the present invention should fall within the scope of the claims of the present invention. Furthermore, although specific terms are employed herein, they are used in a generic and descriptive sense only and not for purposes of limitation.
