Detailed Description

The present invention will now be described in more detail with reference to the accompanying drawings, which show preferred embodiments of air caps constructed in accordance with the present invention.

Referring to FIGS. 2-3, the illustrated air faucet, generally shown in FIG. 2, includes a faucet body 1 and a lift tab 2.

The air tap body 1 is provided with a vertical annular side wall 10 and an air charging and discharging hole 101 arranged in the middle, the end part of one side of the annular side wall 10 extends outwards from the circumferential direction to form an annular flange 11, the annular flange 11 is used as a connecting part for connecting a lifting pull piece 2, part of the annular flange 11 is connected with the lifting pull piece 2, the lifting pull piece 2 is provided with a flexible connecting part 20 connected with part of the edge of the annular flange 11 and a lifting and pulling part 21 extending from the connecting part 20, the connecting part 20 made of flexible materials enables the lifting pull piece 2 to be bent and rotated, and a plug part 210 on the lifting and pulling part 21 is buckled and sealed in the air charging and discharging hole 101 to close a channel. The air nozzle body 1 and the lift tab 2 as described above may be integrally formed by using a suitable molding means such as a plastic material in an injection molding machine.

As further illustrated with reference to fig. 2-3, the plug portion 210 is generally bowl-shaped in configuration, formed with an annular locking projection 211 that projects radially outwardly at an upper end of the outer peripheral surface. In the embodiment shown, the charging and discharging hole 101 is internally provided with an annular groove 102, the annular locking bulge 211 outside the plug part 210 is equivalent to an additional sealing ring, when the plug part 210 seals the charging and discharging hole 101, the annular locking bulge 211 is matched with the annular groove 102 for sealing, and the protruding annular locking bulge 211 can be embedded in the annular groove 102, so that the falling-off risk is reduced.

In the plug portion 210 of this embodiment, the plug portion 210 further has a plug 212 extending outward from the upper end of the upper surface of the lifting portion 21 inside the plug portion 210, a groove 2101 is left between the plug 212 and the inner wall of the plug portion 210, such plug 212 can change the force applied to the middle portion of the plug portion 210, and adjust the force applied area to the outer wall area of the groove 2101, which is beneficial for the annular locking protrusion 211 to be attached to the ring groove 102 more tightly, so as to reduce the influence of the deformation on the sealing effect of the outer wall of the plug portion 210, on the other hand, the arrangement of the plug 212 can increase the bearing strength of the plug portion 210, so that the bearing capacity of the plug portion 210 is improved, the deformation amount is reduced, and the arrangement of the groove 2101 also enables the plug portion 210 to be buckled into the air hole 101.

In fig. 3, in order to ensure uniform stress, the plug 212 is disposed at the middle of the plug 210, and the plug 212 is configured in an arc-shaped arch structure, so that the whole stress is transmitted to the outer wall of the plug 210 to achieve an outward expansion effect, thereby the plug 210 is more tightly attached to the inflation/deflation hole 101.

When the plug portion 210 of the lift tab 2 is detached from the inflation/deflation hole 101 to perform inflation/deflation, as shown in fig. 2, the lift portion 21 of the lift tab 2 is pinched with a finger to pull the lift tab 2 upward. In this case, in order to improve the anti-slip effect, anti-slip stripes 213 are provided on the front and/or back of the lift-pull portion 21 to increase friction with the hand and prevent slipping.

While the utility model has been described with reference to a preferred embodiment, it will be understood by those skilled in the art that various changes in form and detail may be made therein without departing from the spirit and scope of the utility model.
