Abstract
An auto-inflating cushion structure includes an outer covering and an inner filling body. The inner filling body is accommodated in the outer covering and has a three-dimensional shape in a normal state. The outer covering is provided with an air valve unit. When not in use, the cushion can be compressed to become thin, thereby reducing the volume without occupying space. When in use, the external air flows into the outer covering, in cooperation with the expansion of the inner filling body, so that the interior of the cushion is automatically inflated. The cushion can serve as an auxiliary support for a user lying on his/her side. In particular, the storage is quite space-saving and the cushion is practical.
Claims
1. An auto-inflating cushion structure, comprising an outer covering and an inner filling body, the outer covering being formed with an opening, the opening being provided with an air valve unit; the inner filling body being accommodated in the outer covering and having a three-dimensional shape in a normal state.
2. The auto-inflating cushion structure as claimed in claim 1, wherein the outer covering is made of an air-impermeable material in a three-dimensional bag-like configuration.
3. The auto-inflating cushion structure as claimed in claim 1, wherein the outer covering and the inner filling body each have a wedge shape.
4. The auto-inflating cushion structure as claimed in claim 3, wherein the inner filling body is made of a PU (polyurethane) material.
5. The auto-inflating cushion structure as claimed in claim 1, wherein a filter member is provided inside the air valve unit.
6. The auto-inflating cushion structure as claimed in claim 1, wherein the air valve unit includes a base, a through hole is defined in the base for air circulation; a sleeve and a sleeve cover are connected to the base and located beside the base.
7. The auto-inflating cushion structure as claimed in claim 6, wherein the sleeve serves as a one-way check valve, the sleeve is inserted in the through hole; the sleeve cover is configured to cover an outside of the base.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS
[0019] Embodiments of the present invention will now be described, by way of example only, with reference to the accompanying drawings.
[0020] As shown in
[0021] When the product of the present invention is finished, the air inside the product is almost completely discharged by applying pressure to the outside of the outer covering 1. The inner filling body 2 is compressed, and the air valve unit 12 is closed to make the entire cushion thin and compressed, as shown in the upper part of
[0022] When in use, the sleeve 122 and the sleeve cover 123 are flipped outwardly to open the air valve unit 12. The pressure difference allows the external air to flow into the outer covering 1, in cooperation with the expansion of the inner filling body 2, so that the interior of the cushion is automatically inflated (as shown in the lower part of
[0023] Although particular embodiments of the present invention have been described in detail for purposes of illustration, various modifications and enhancements may be made without departing from the spirit and scope of the present invention. Accordingly, the present invention is not to be limited except as by the appended claims.
