The application provides an air valve support piece which comprises a continuous skirt, a spaced skirt and a top cover; the continuous skirt is provided with an air outlet; one end of the spaced skirt edge is arranged on the continuous skirt seat, and the spaced skirt edge is provided with at least one air outlet channel; the top cover is connected with the other end of the spaced skirt, the top cover and the spaced skirt enclose an air outlet cavity together, and the air outlet cavity is respectively communicated with the air outlet and the air outlet channel.

Referring to fig. 1-5, to better understand the valve support 10 of the present application, the valve support 10 is further explained as follows:

the valve support 10 of one embodiment includes a continuous skirt 100, a spaced skirt 200, and a top 300; continuous skirt 100 has an air outlet 102; one end of the spaced skirt 200 is arranged on the continuous skirt 100, and the spaced skirt 200 is provided with at least one air outlet channel 202; the top cover 300 is connected with the other end of the spaced skirt 200, and the top cover 300 and the spaced skirt 200 together enclose an air outlet cavity 302, and the air outlet cavity 302 is respectively communicated with the air outlet 102 and the air outlet channel 202. Because the air valve supporting member 10 of the conventional inflatable mask 30 is locally pressed (by human body action or air pressure difference), the air valve supporting member 10 deforms by pressing, and the air valve supporting member 10 has a single air outlet 102, which is prone to problems such as the diameter of the air outlet 102 suddenly decreases, and the like, thereby resulting in unsmooth air outlet. Therefore, in this embodiment, at least one gas outlet channel 202 is formed in the partition skirt 200, so that the gas is output through the gas outlet 102 to the whole gas valve support 10, and then the gas is output through the gas outlet channel 202. When air valve support member 10 is under the extrusion force, partial or whole extrusion force is offset by air pressure, make air valve support member 10 indeformable or the deformation degree is less, consequently can not appear the problem that the gas outlet 102 footpath of gas outlet 102 suddenly diminishes, thereby promoted air valve support member 10's structural stability, and then improved air valve support member 10's the smooth and easy degree of giving vent to anger.

As shown in fig. 4 and 5, in one embodiment, the continuous skirt 100 includes a plurality of mounting edges 110, and the mounting edges 110 are sequentially connected end to form a frame structure. It will be appreciated that the continuous skirt 100 has a plurality of mounting edges 110, the plurality of mounting edges 110 being sequentially connected end to form a frame structure to form a to-be-mounted frame skirt.

As shown in fig. 4 and 5, in one embodiment, the continuous skirt 100 includes four mounting edges 110, and the four mounting edges 110 are sequentially connected together end-to-end to form a rectangular frame structure. It can be understood that, the rectangular frame structure formed by the four mounting edges 110 has stable structural strength, occupies a small space, and has a simpler molding and manufacturing process compared with a polygonal frame structure, thereby effectively improving the structural strength and structural stability of the air valve support 10.

As shown in fig. 4 and 5, in one embodiment, the partition skirt 200 is provided with two air outlet channels 202, the partition skirt 200 has a rectangular frame structure, and the plane of each side edge of the partition skirt 200 is perpendicular to the plane of the continuous skirt 100; and the two outlet channels 202 are oppositely arranged. It should be noted that, since the continuous skirt 100 forms a rectangular frame structure and the partition skirt 200 is correspondingly mounted on the continuous skirt 100, the partition skirt 200 also has a rectangular frame structure. Specifically, the plane of each side of the spaced skirt 200 is perpendicular to the plane of the continuous skirt 100, so that the air valve support 10 forms a rectangular frame structure. Two air outlet channels 202 have been seted up to compartment skirt 200, and two air outlet channels 202 opposite direction set up, make gas export to two air outlet channels 202 and carry through whole rectangle framework through gas outlet 102, when gas valve support piece 10 received the extrusion force, partial or whole extrusion force is offset to atmospheric pressure, gas valve support piece 10 does not deform or deformation degree is less, consequently, the problem that the gas outlet 102 footpath of gas outlet 102 suddenly diminishes can not appear, thereby the structural stability of gas valve support piece 10 has been promoted, and then the smooth and easy degree of giving vent to anger of gas valve support piece 10 has been improved.

As shown in fig. 4 and 5, in one embodiment, the air outlet channels 202 on the spaced skirt 200 have a top edge at a first distance from the top cap 300 and a bottom edge at a second distance from the continuous skirt 100. It should be noted that the top edge of the air outlet channel 202 on the spaced skirt 200 has a first distance from the top cap 300, and the bottom edge has a second distance from the continuous skirt 100, so that the spaced skirt 200 and the top cap 300 and the continuous skirt 100 have a mutual pulling force, and the air valve supporting member 10 is not easily deformed when being subjected to an extrusion force, thereby effectively improving the structural stability of the air valve supporting member 10, and further effectively improving the air outlet smoothness of the air valve supporting member 10.

In one embodiment, as shown in fig. 4 and 5, the continuous skirt 100, the spaced skirt 200, and the top cap 300 are integrally formed.
