The present invention will be further described in detail below with reference to the accompanying drawings and embodiments. It is understood that the specific embodiments described herein are merely illustrative of the invention and are not intended to limit the invention.

[0028] It is to be noted that when an element is referred to as being "fixed" or "in" another element, it can be directly on the other element or the same. When an element is referred to as being "connected" to another element, it can be directly connected to the other element or.

[0029] It should also be noted that the left, right, upper, lower, and the like orientation terms in this embodiment are only relative concepts or reference to the normal use state of the product, and should not be considered as having limitations. Sexual.

1 to 4, a gas nozzle according to an embodiment of the present invention includes a nozzle body 10, a nozzle cover 20 for sealing the nozzle body 10, and a "T"-shaped seal in cross section. Pad 30. The gasket 30 includes a flat end 31 and a column end 32 that are vertically connected, and the flat end 31 is integrally formed with the column end 32. The air nozzle main body 10 has a cylindrical shape as a whole, and has a receiving cavity 11 at the inner portion thereof. The bottom of the receiving cavity 11 has a through hole 12 through which the gasket 30 is mounted. Specifically, the flat end 31 of the gasket 30 abuts against the outer wall of the accommodating chamber 11 and seals the vent 12, and the column end 32 extends into and is fixed in the accommodating chamber 11. When the above nozzle is applied to the inflatable headrest, the design of the flat end 31 increases the contact area with the gas in the inflatable headrest, and when the internal gas of the inflatable headrest squeezes it, the flat end 31 abuts against the nozzle body. The bottom of the 10 is sealed with the air vent 12 to prevent internal gas from escaping from the nozzle body 10. The receiving chamber 11 is provided with a pressing member 13 through which the bottom of the pressing member 13 is in contact with the flat end 31 of the gasket 30. When the pressing member 13 is pressed, the bottom end of the pressing member 13 will be the flat end 31 of the sealing member 30. Jacking outward causes a gap between the flat end 31 and the air vent 12 to allow gas to pass through the gap to effect deflation.

[0031] In the present invention, the gas nozzle adopts a "T"-shaped gasket 30, and the air hole 12 is sealed by the flat end 31 of the gasket 30, when the gas nozzle is applied to the inflatable head pillow, and the gasket 30 is in the inflatable head pillow. The inside is pressed by the internal gas, and the flat end 31 abuts against the bottom of the nozzle body 10 to prevent the internal gas from escaping from the nozzle body 10. When the pressing member 13 is pressed, the pressing member 13 is placed on the side of the flat end 31.幵, the gap between the flat end 31 and the bottom of the nozzle body 10 is generated, and the gas in the inflatable headrest is released. The air nozzle has a simple overall structure and a reasonable design, and can effectively prevent the gas inside the inflatable headrest from escaping. Good sealing performance.

[0032] Specifically, in the embodiment of the present invention, the center of the accommodating cavity 11 is provided with a stepped mounting hole 14 and the column end 32 is extended. The mounting hole 14 is inserted into the mounting hole 14 , and the outer wall of the column end 32 is provided with a boss 321 . The boss 321 is locked at the step of the mounting hole 14 , so that the column end 32 is firmly fixed in the receiving cavity 11 .

[0033] In this embodiment, the end of the column end 32 away from the flat end 31 has a smooth transition surface 322. In this way, after installation吋

The cylindrical end 32 can be easily inserted into the mounting hole 14 by the smooth transition surface 322.

[0034] As a preferred solution, there are a plurality of air holes 12, and a plurality of air holes 12 are evenly distributed around the column end 32 of the gasket 30.

. Of course, the pores 12 can also be non-uniformly distributed. The number and shape of the air holes 12 can be selected according to actual needs.

[0035] In this embodiment, the gasket 30 is made of a silicone rubber or a rubber material. Of course, it can also be made of other flexible materials.

Referring to FIGS. 1 and 2, the nozzle body 10 and the nozzle cover 20 are connected by a connecting member 40. In this way, avoid the nozzle cover

The detachment from the nozzle body 10 causes the nozzle cover 20 to be lost.

[0037] Preferably, the nozzle body 10, the connecting member 40 and the nozzle cover 20 are integrally formed. Further, the inner side of the connecting member 40 has a folded groove 41 formed inwardly recessed. Thus, when the air nozzle cover 20 seals the air nozzle main body 10, the connecting member 40 can be bent better along the folding groove 41, preventing the connecting member 40 from being bent in the reverse direction and pulling the air nozzle cover 20.

In the embodiment, the end of the gas nozzle cover 20 away from the nozzle body 10 is provided with a hand piece 50, and the hand piece 50 is used to facilitate the extraction of the nozzle cover 20 from the nozzle body 10. In order to facilitate pulling the hand piece 50, a friction block 51 is further provided on the hand piece 50.

[0039] In the embodiment, the inner side of the gas nozzle cover 20 is provided with a male plug 21 that can extend into the accommodating cavity 11, and the outer diameter of the male plug 21 matches the inner diameter of the cavity of the accommodating cavity 11, so that the male plug 21 extends. The accommodating cavity 11 吋 completely seals the opening of the accommodating cavity 11 , and the annular stripe 22 provided on the side wall of the plug 21 facilitates the insertion of the plug 21 to be stronger and the sealing effect is better.

[0040] Embodiments of the present invention also provide an inflatable headrest (not shown) provided with the above-mentioned air nozzle. When the above-mentioned air nozzle is applied to the inflatable headrest, the working principle is as follows: the air nozzle is mounted on the inflatable headrest, and the gasket 30 is pressed by the internal gas in the inflatable headrest, and the flat end 31 is closely attached to the nozzle body 10 The bottom portion seals the air hole 12 to effectively prevent the internal gas from escaping from the nozzle body 10. When the pressing member 13 is pressed, the pressing member 13 pushes the side of the flat end 31 so that the flat end 31 and the bottom of the nozzle body 10 are generated. The air gap releases the gas in the inflatable headrest. The above-mentioned air nozzle has a simple structure and a reasonable design, and can effectively prevent the gas inside the inflatable headrest from escaping, and has good sealing performance. The above are only the preferred embodiments of the present invention, and are not intended to limit the present invention. Any modifications, equivalents, and improvements made within the spirit and scope of the present invention should be included in the scope of the present invention. Inside.
