CN2209486Y - Cooling cushion - Google Patents

Abstract

The utility model relates to a cooling cushion, which is a cooling cushion made by the characteristic that substance slowly melting and fast crystallizing absorbs heat and reduces temperature constantly for a long time. The cooling cushion is mainly made of a soft sealed outer housing made by polyvinyl chloride nylon cloth base through dielectric sealing and cooling agent in the inner cavity of the sealed outer housing. In hot environment in summer, the cooling cushion can continuously absorb hear and reduce temperature for a long time, and consequently reduces the temperature of part of the human body, making people feel cool. The utility model can relieve dysphoria and discomfort for people caused by high temperature.

Description

Cooling cushion

The utility model relates to a kind of cool pad, is to utilize material to dissolve---and the repetitive process neither endothermic nor exothermic of crystallization is regulated the cold pad of temperature.

Existing cool pad mostly is the interior dress of bamboo, cotton products or plastic cement sealing shroud thermal medium and makes, so that it reaches the temperature adjustment purpose.Weak points of these cool pads are: the heat absorption heat release temperature difference is too small in summer high temperature environment, can not absorb heat in a long time and gives nice and cool impression.The disclosed a kind of constant temperature pad of Chinese patent CN2121872U, it coagulates fusing point is 28-30 ℃, also can not make the people that the cooling feeling of long period is arranged in summer high temperature environment.

The purpose of this utility model is to overcome above-mentioned weak point of the prior art and a kind of cold pad that can the long period absorbing and cooling temperature in summer high temperature environment is provided.

For finishing above-mentioned purpose, technical solution of the present utility model is: a kind of cold pad of forming through high frequency heat seal soft can of making and the cooling agent that is loaded in it with polyvinyl chloride nylon fabricbase, the cavity shape of soft can is made arranged side by side and continuous strip (also can be made into the curve strip of intercommunication), and this strip can make the inner chamber fill all issue and can not flow to a certain part.The cooling agent that is loaded on soft can inner chamber is made up of sal glauberi and solution thereof and water absorbing agent, the sal glauberi crystalline solid absorbs heat to dissolve gradually in summer high temperature environment and is the aqueous solution, sustainable 6 hours of its heat absorption cooling procedure, make cool pad with this cooling agent, can make body local feel nice and cool for a long time.The sal glauberi crystalline solid heat absorption of can inner chamber is dissolved for behind the aqueous solution, available running water dashes and drenches can (being this cold pad) about 30 minutes (or it is of short duration freezing to put into refrigerator), the sal glauberi solution of its inner chamber is rapidly crystallization again, thisly slowly dissolves---and the repetitive process of crystallization rapidly just in time can be used for making the cold pad that reduces the body local temperature.Solution in the cooling agent is water, its water absorbing agent is 500 times of hydroscopic high-molecular resins, water, water absorbing agent, sal glauberi merge the concentration that can regulate peace weighing apparatus cooling agent mutually, make cool pad continue the cooling effect of performance long period, and can make cool pad keep soft feeling and elasticity.

Advantage of the present utility model is can continue in summer high temperature environment for a long time, and thereby heat absorption reduces the body local temperature, makes the people feel nice and cool, can be made into cool pad, a kind of pillow used in summer absorbing and cooling temperature material, can improve agitation and sense of discomfort that people cause because of summer high temperature.

Accompanying drawing has been described an embodiment of the present utility model.

Fig. 1 is a horizontal sectional drawing of the present utility model.

Fig. 2 is the A-A cut-away view of Fig. 1.

With reference to Fig. 1, Fig. 2, the soft can (1) of this cold pad is to make through high frequency heat seal with polyvinyl chloride nylon fabricbase (Q-29), its cavity shape is arranged side by side and continuous strip, and inner chamber is equipped with cooling agent (2) sal glauberi and solution and micro-water absorbing agent.Sal glauberi is a crystalline solid, and heat absorption is dissolved gradually and is the aqueous solution in summer high temperature environment, sustainable 6 hours of its heat absorption cooling procedure, and the utility model utilizes just and thisly slowly dissolves---the repetitive process of crystallization rapidly and the cold pad made.Solution in the cooling agent is water, and its addition is 10% of a sal glauberi; Water absorbing agent is 500 times of hydroscopic high-molecular resins, and its addition is 1/500th of a sal glauberi.The sal glauberi crystalline solid heat absorption of can inner chamber is dissolved for behind the aqueous solution, available running water dashed pouring can (being this cold pad) about 30 minutes or put into refrigerator of short duration freezing, the sal glauberi solution of its inner chamber is crystallization rapidly again, and cool pad can use repeatedly.

Claims (2)

1, a kind of soft can of being made through high frequency heat seal by polyvinyl chloride nylon fabricbase and be loaded on the cold pad that the cooling agent in it is formed is characterized in that: cooling agent is made up of sal glauberi and solution thereof and water absorbing agent.

2, cool pad according to claim 1, it is characterized in that: the solution in the cooling agent is water, its water absorbing agent is 500 times of hydroscopic high-molecular resins.
