Description

Ventilated Air Cushion

The utility model is related to the air cushion, more specifically, it refers to a ventilated air cushion which allows the air supplied by cold or warm air to circulate in the air cushion sequentially to change the surface temperature of the air cushion.

From the early beaded, straw, and bamboo woven sitting and lying cushions to today's water cushions and air cushions, most of them are developed to reduce the temperature where the user sits or lies to achieve a cool effect. However, the early sitting and lying pads can only enjoy the cooling effect when they are just used. After a period of use, the pad body will still retain the body temperature and lose the cool feeling unless the pad body is left to fully dissipate heat. Otherwise, the cooling effect will be greatly reduced due to continuous use.

Nowadays, the water cushions filled with clear water or chemical agents in the cushion body have a lower surface temperature than the early bamboo and straw cushions, and the coolness lasts slightly longer, but because the solution in the water cushion stays in the cushion body permanently, and the water cushion The surface cloth is made of airtight and water-proof plastic cloth. After sitting and lying for a period of time, the body temperature will be transmitted to the surface cloth and its inner solution, making it lose the cooling effect, and replaced by the uncomfortable feeling of warm and sticky on the surface cloth of the cushion body ; and the temperature of the water pad is easily affected by the surrounding environment and changes. In a higher temperature environment (such as a car body exposed to the hot sun), the water pad almost becomes a warm pad, which cannot play a cooling effect at all; on the contrary, in winter In a low temperature environment, the water cushion is even colder, and users dare not use it at all.
