Abstract

The present invention introduces an air valve comprising a hollow annular base mount (10), which is combined with a flexible enclosure (51), and a detachable valve core (20) that is coupled with the base mount (10). The valve core (20) is designed in a recess-like configuration, defining an internal air chamber (211). An air passage (22) extends through the valve core (20), within which a valve plug (30) is positioned to seal the air passage (22). The valve plug (30) includes a flap valve (31) that lifts toward the air chamber (211) when suction is applied, thereby establishing communication between the air passage (22) and the air chamber (211). The valve core (20) of the air valve can be selectively detached to facilitate the inflation, deflation, filling, and firmness adjustment of a filled product (50), offering a versatile range of functionalities.

Dependent claims

An air valve for combining with a flexible enclosure (51), comprising:

a hollow annular base mount (10) including a mounting flange (11) radially extending from the outer wall of the base mount (10) for combining with the flexible enclosure (51);
a valve core (20) axially inserted into the base mount (10) and detachably combined with the base mount (10) outside the flexible enclosure (51), the valve core (20) being recess-like and defining an air chamber (211) therein, the valve core (20) including a barrier wall (21) at a sealed end (201) adjacent the base mount (10) and an air passage (22) penetrating the barrier wall (21), with a passage ring (23) surrounding the air passage (22) and axially extending towards the air chamber (211);
a valve plug (30) provided within the air passage (22), including a flap valve (31) at one end to seal the air passage (22), the flap valve (31) responding to suction or pushing force by lifting to allow the air passage (22) to communicate with the air chamber (211);
and
an air valve cover (40) detachably coupled with the valve core (20) and sealing the air chamber (211).

A filled product comprising a flexible enclosure (51) with an opening (52) at any location, the opening (52) provided with an air valve, the air valve comprising:

a hollow annular base mount (10) including a mounting flange (11) radially extending from the outer wall of the base mount (10), the base mount (10) passing through the opening (52), with one side of the mounting flange (11) fixed to the flexible enclosure (51);
a valve core (20) axially inserted into the base mount (10) and detachably combined with the base mount (10) outside the flexible enclosure (51), the valve core (20) being recess-like and defining an air chamber (211) therein, the valve core (20) including a barrier wall (21) at a sealed end (201) adjacent the base mount (10) and an air passage (22) penetrating the barrier wall (21), with a passage ring (23) surrounding the air passage (22) and axially extending towards the air chamber (211), wherein when the valve core (20) is combined with the base mount (10), the air chamber (211) faces outside the flexible enclosure (51);
a valve plug (30) provided within the air passage (22), including a flap valve (31) at one end to seal the air passage (22), the flap valve (31) responding to suction or pushing force by lifting to allow the air passage (22) to communicate with the air chamber (211);
and
an air valve cover (40) detachably coupled with the valve core (20) outside the flexible enclosure (51) and sealing the air chamber (211).
