Description

Technical Field

[0001] The present invention relates to a heat-insulating inflatable product. Background Art

[0002] Various types of inflatable products are favored by consumers due to their advantages such as light weight, collapsible, easy to carry, and convenient to use. For example, the patent document CN207568250U discloses an inflatable pool, which includes an inflatable pool body for holding water. The inflatable pool body includes an inflatable side wall and a bottom. The inflatable side wall can be designed in any shape, usually mainly circular or regular polygons. More specifically, the inflatable side wall includes an inner wall, an outer wall, an upper wall, and a lower wall, and an inflatable space is defined by the inner wall, the outer wall, the upper wall, and the lower wall. A tension member is provided in the inflatable space to limit the shape change of the inflatable side wall after inflation. The tension member exerts opposite pulling forces on the inner wall and the outer wall. Among them, the tension member is usually a thin sheet or a mesh strap.

[0003] In daily use, the inflatable side wall usually has a certain heat-insulating effect, but there is still room for further improvement in its heat-insulating performance. In particular, users need to keep the water in the inflatable pool warm in some scenarios. However, the heat-insulating performance of the inflatable pool body itself is limited, and there is a lot of heat energy dissipation, making it difficult to meet the heat-insulating needs of users. In the current market, merchants provide a pool cover added to the inflatable pool body to cover the inflatable pool body. The pool cover generally includes a top cover and an outer cover made of heat-insulating materials. The top cover covers the upper part of the inflatable pool body, and the outer cover surrounds the inflatable side wall. The top cover generally has an inflatable inner liner, but there is still room for further improvement in the heat-insulating effect of the inner liner. Summary of the Invention

[0004] The purpose of the present invention is to provide a heat-insulating inflatable product with improved heat-insulating performance.

[0005] To this end, the present invention provides a heat-insulating inflatable product, including: a first wall; a second wall, jointly defining an inflatable chamber with the first wall; a tension structure, located in the inflatable chamber and connecting the first wall and the second wall; and a reflective structure, constrained by the tension structure and fixed in the inflatable chamber.

[0006] In some embodiments, the tension structure includes a first tension member connected to the first wall and a second tension member connected to the second wall, and the first tension member is connected to the second tension member.

[0007] Optionally, the reflective structure includes a first reflective film constrained by the first tension member and the second tension member.

[0008] Optionally, the reflection structure includes a first reflective film constrained by the first tension member and the first wall, a second reflective film and a third reflective film constrained by the first tension member and the second tension member, and a fourth reflective film constrained by the second tension member and the second wall.

[0013] Optionally, the reflection structure includes a first reflective film constrained by the first tension member and the second wall.

[0014] Optionally, the reflection structure includes a first reflective film constrained by the first tension member and the first wall, and a second reflective film constrained by the first tension member and the second wall.

[0015] Optionally, the first tension member includes a plurality of first tension pieces connected to each other in pairs.

[0016] Optionally, the first tension member includes a plurality of first tension pieces arranged at uniform intervals.

The second tension member 2725 includes a plurality of second tension pieces 2726, and the plurality of second tension pieces 2726 are sequentially connected in the inflation chamber. Each second tension piece 2726 has a second side 2727 and a lower side 2728 that are away from each other. Among two adjacent second tension pieces 2726, the lower side 2728 of one second tension piece 2726 is connected to the lower side 2728 of the other second tension piece 2726, and the second side 2727 of one second tension piece 2726 is connected to the second side 2727 of the other second tension piece 2726.

[0101] Refer to Figure 14C, the first reflective film 2731 is disposed between the plurality of first tensioning sheets 2722 and the upper wall 2711 and is fixed under the constraint of the first tensioning sheets 2722 and the upper wall 2711. The fixing manner of the first reflective film 2731 between the first tensioning sheets 2722 and the upper wall 2711 can refer to the description in the tenth embodiment. The second reflective film 2732 and the third reflective film 2733 are disposed between the plurality of first tensioning sheets 2722 and the plurality of second tensioning sheets 2726 and are fixed under the constraint of the corresponding first tensioning sheets 2722 and second tensioning sheets 2726. In a specific process, the second reflective film 2732 and the third reflective film 2733 can be disposed between the first side 2724 of the first tensioning sheet 2722 and the second side 2727 of the second tensioning sheet 2726, and the first side 2724, the second reflective film 2732, the third reflective film 2733, and the second side 2727 are simultaneously welded and fixed; alternatively, a plurality of through holes are respectively formed in the second reflective film 2732 and the third reflective film 2733, the second reflective film 2732 and the third reflective film 2733 are disposed between the first side 2724 of the first tensioning sheet 2722 and the second side 2727 of the second tensioning sheet 2726, the through holes in the second reflective film 2732, the through holes in the third reflective film 2733, the first side 2724, and the second side 2727 are equal in number and are in one-to-one correspondence in position, and after the corresponding first side 2724 and second side 2727 are respectively welded and fixed through the through holes in the second reflective film 2732 and the through holes in the third reflective film 2733, the second reflective film 2732 and the third reflective film 2733 are fixed under the clamping action of the first side 2724 and the second side 2727. In this process, the area profiles of the first side 2724 and the second side 2727 are respectively larger than the area profiles of the through holes in the second reflective film 2732 and the through holes in the third reflective film 2733. The fourth reflective film 2734 is disposed between the plurality of second tensioning sheets 2726 and the lower wall 2712 and is fixed under the constraint of the second tensioning sheets 2726 and the lower wall 2712. The fixing manner of the fourth reflective film 2734 between the second tensioning sheets 2726 and the lower wall 2712 can be similar to the fixing manner of the first reflective film 2731 between the first tensioning sheets 2722 and the upper wall 2711.

[0102] According to another implementation variant, the plurality of first tensioning sheets 2722 can be sequentially arranged at uniform intervals in the inflation chamber, and / or the plurality of second tensioning sheets 2726 can be sequentially arranged at uniform intervals in the inflation chamber.

[0103] The tensioning sheet can be made of the same polymer material as the inner wall, outer wall, upper wall, lower wall of the inflatable sidewall and the upper wall and lower wall of the inflatable inner bladder. For example, the tensioning sheet can be made of one or a combination of polyvinyl chloride (PVC), thermoplastic polyurethane elastomer (TPU), polyurethane (PU), polypropylene (PP), polyethylene (PE), polyethylene terephthalate (PET), nylon, and other suitable polymer materials.

[0104] The reflective film can be formed by a single reflective sheet or includes multiple reflective sheets. When there are multiple reflective sheets, these reflective sheets are fixedly connected in sequence, for example, at the connection position where the reflective structure is connected to the tensioning structure. The reflective sheet is, for example, a heat-insulating film sheet including a polymer substrate and a metal coating plated on at least one of the front and back surfaces of the polymer substrate. Such a heat-insulating film sheet has a good function of reflecting thermal radiation, thereby being able to reduce the heat loss in the inflatable pool and improve the heat preservation performance of the inflatable pool itself. The polymer substrate of such a heat-insulating film sheet can be made of one or a combination of polyvinyl chloride (PVC), polypropylene (PP), polyethylene terephthalate (PET), and other suitable polymer materials, and the metal coating can be made of one or a combination of aluminum, zinc, copper, silver, gold, and other suitable metal materials. In addition, the reflective sheet can also be a single sheet body with a layer structure formed by fixing multiple film sheets together.

[0105] It can be understood that according to other implementation variants not shown, the features of the various different embodiments described above can be combined with each other. For example, in the same inflatable pool, the inflatable sidewall can adopt any one of the first to seventh embodiments described above, while the inflatable inner bladder of the top cover can adopt any one of the eighth to fourteenth embodiments described above. Also for example, the inflatable sidewall can adopt a combination of any multiple of the first to seventh embodiments described above, or the inflatable inner bladder of the top cover can adopt a combination of any multiple of the eighth to fourteenth embodiments described above.

[0106] The technical content and technical features of the present invention have been disclosed above. However, it is understood that under the creative concept of the present invention, those skilled in the art can make various changes and improvements to the above-disclosed concept, but all belong to the protection scope of the present invention.

[0107] The description of the above embodiments is exemplary rather than restrictive, and the protection scope of the present invention is determined by the claims.
