Cooling pad

Abstract

The invention discloses a cooling pad, which comprises an outer bag and functional materials filled in the outer bag, wherein the functional materials comprise more than one of sodium sulfate decahydrate, sodium carbonate dodecahydrate or sodium chloride and more than two of water, polyvinyl alcohol, sodium polyacrylate, sodium carboxymethylcellulose, hydroxyethyl sodium carboxymethyl cellulose, sodium borate, ethylene glycol, polyethylene glycol, span-80 or calcium chloride. In the cooling pad, the process is simple, the energy consumption is not needed, the contents are not easily splashed out to cause the dirty surface of a product, the bad phenomena of concave marks on the surface and the like are avoided, the whole product is attractive and practical, and the air in the bag does not need to be eliminated; and more importantly, by ITS (intelligent transportation system) special detection, the result shows that under the same conditions, after a human body sleeps for 6 hours, the temperature of the human body adopting the cooling pad is 3-4 DEG C lower than that adopting the prior art, and the human body feels cooler, so that people can go sleep smoothly under the condition of hot summer without energy consumption. The cooling pad is economical and environmentally-friendly.

Description

technical field [0001] The invention relates to a cooling product, in particular to a cooling pad filled with internal functional materials Background technique [0002] There have been many proposals to place a device on top of the bedding used to cool a subject (for example, on a sleepless summer night) that can directly cool the subject, for example by flowing cooling air into a futon and / or pillow that cools the subject body device. For example, airflow type futons are filled with a coarse cotton material, or a three-dimensional fiber material to allow air to flow through the filling. These cotton materials and three-dimensional fiber materials serve as spacers to allow air to flow around them. That is, the members of the nesting futon overlap each other through the spaces used as air flow passages. In addition to the above-mentioned cotton material and three-dimensional fiber material, the spacer used on the air circulation type cooling device includes a foamed spong...

Problems solved by technology

[0004] In order to overcome the above-mentioned defects, Chinese patent 99815757 provides a cooling product, but still does not break away from the framework of the traditional cooling product

[0005] In recent years, corresponding cooling pad products have appeared in the society, such as the patent "gel pad and its production method" application number: 200810063081.4, this product can partially solve the above problems, but the cool time is not long enough, and the cool feeling is not very obvious and other issues, and caused instability in the Japanese market in 2009

In addition, when producing this product, there are long "dents" on the product surface; it is easy to splash the contents on the outer packaging material and cause the surface of the product to be dirty; if the air in the bag is not completely squeezed out when sealing, the product surface will have Many "pits" of different sizes affect the appearance; the production process requires hot pressing, which consumes more energy; after the product is produced, it needs to be cooled before packaging, resulting in defects such as cumbersome process and large factory footprint.
