Description

Cushion structure

The present invention relates to a cushion structure, especially a cooling or heating of the cushion through a single circulation channel.

The sitting or lying position is usually longer than the standing position during the day. Most people usually use soft cushions or sleeping pads to make sitting and lying more comfortable. However, when the user sits or sleeps for a long time, the contact between the body and the seat cushion or sleeping pad will cause a feeling of stuffiness and discomfort due to the lack of ventilation, especially in hot summer.

In order to solve this problem, there is currently a soft pad that can be filled with water or other liquids. Although the liquid in the soft pad has the effect of dissipating heat and lowering temperature, the liquid in the soft pad does not circulate in a circulating manner. In addition, the material of the soft pad must be an airtight waterproof material, so when the user sits for a long time, the heat energy cannot be dissipated outward, and the feeling of stuffiness is still produced, which shows its shortcomings.

For this reason, as shown in Taiwan Invention Patent No. I343880 "Improvement of the Cushion Body Structure", the cushion body (1) disclosed in this case is composed of a soft upper sheet body (1a) and a lower sheet body (1b) which are relatively hot. It is formed by fusion and pressing, by thermal fusion bonding of appropriate blocks (10) between the upper sheet body (1a) and the lower sheet body (1b), so that the part that is not thermally bonded is formed There are a large number of water diversion channels (11) that are connected with each other for the water to flow in the interior, so that the water flow can flow between the parts that are not thermally fused to achieve the cooling effect.

However, the pad body disclosed in the case of No. I343880 needs to be thermally fused and bonded by at least one set of molds and high frequency waves, so the manufacturing process is complicated and the manufacturing cost is increased. In addition, the cushion body disclosed in the case No. I343880, as shown in Fig. 9, is usually heated by two soft adhesive layers. Fusion and fit, although it is filled with liquid, the soft adhesive layer cannot support the user's weight at all. When the user sits or lies on the pad body, the "non-thermal fusion fit" at the contact part between the body and the pad body. The "place" will be flattened and completely fit, as shown in the section (A) of Figure 8. In this region (A), the original unobstructed passage will be compressed and closed, which will hinder the passage of the water flow there. Therefore, most of the The water flow (L) will flow from the uncompressed "unheated joint" with less resistance, resulting in the water flow in this area (A) being unable to flow smoothly. The contact part of the pad body still cannot obtain a good and reliable heat dissipation effect. After sitting or lying down for a long time, it will still produce stuffy and uncomfortable. Similar structures such as Taiwan No. M332424 have their shortcomings and need to be improved.

In view of this, the inventor of the present case has made further research and innovation, and finally revealed the structure of the pad body disclosed in the present invention.
