In order to achieve the above object, the utility model provides a following technical scheme: the utility model provides an airtight sealing head, includes base and sealed head of gluing, the base is located sealed head of gluing directly over, inflation chamber, seal groove and first inlet channel have been seted up respectively to sealed bottom of gluing the head, just the top fixedly connected with of sealed head and the water pipe that first inlet channel corresponds, the second inlet channel has been seted up at the upper surface middle part of base, just the upper surface outside fixed mounting of base has the sealed surrounding edge with the seal groove joint.

Preferably, the cross section of the sealing surrounding edge is of an annular structure, and the sealing surrounding edge and the base are of an integrally formed structure.

Preferably, the water pipe comprises a spherical surface arranged at the lower end, and the spherical surface is positioned at the inner side of the expansion cavity.

Preferably, the expansion cavity is located on the inner side of the sealing groove, and the expansion cavity is of an inverted truncated cone structure.

Preferably, the sealing surrounding edge is made of hard materials such as metal, and the first air inlet channel is communicated with the second air inlet channel.

Preferably, the water pipe and the sealing rubber head are connected to form a T-shaped structure, and the base is of a cylindrical structure.

Compared with the prior art, the beneficial effects of the utility model are as follows:

the utility model discloses a fill into high-pressure gas to first inlet channel and second inlet channel's inside, under the high-pressure condition, inflation chamber department inflation makes the water pipe outer wall more laminate with the first inner wall of sealing glue, prevents gas leakage, and sealing capacity is stronger, and long service life is fit for extensively promoting.
