The present invention is described in terms of specific embodiments, and other advantages and benefits of the present invention will become apparent to those skilled in the art from the following disclosure. Based on the embodiments in the present invention, all other embodiments obtained by a person skilled in the art without creative work belong to the protection scope of the present invention.

As shown in fig. 1, the utility model provides a charge ice bag, including hemispherical ice bag body 1, ice bag body 1 includes plane portion 101 and forms sphere 102 in plane portion 101 one side, forms the cooling chamber 103 that is used for holding condensing medium between sphere 102 and the plane portion 101, and sealing connection becomes a whole between plane portion 101 and the sphere 102.

Wherein, the condensing medium can be water, salt water and the like which can form ice-water mixture at low temperature.

The ice bag body 1 of the embodiment can also be directly put into a refrigerator for freezing and then directly taken out for use, and the condensing medium can be recycled.

Before using, however, in order to facilitate the specific use of each part of the human body, it is generally necessary to wait for the condensing medium in the ice pack body 1 to be partially cooled until the inside is in a state similar to an ice-water mixture.

In order to solve the above-mentioned existing problems, the ice pack body 1 of the present embodiment is improved to an ice pack with a charging type refrigeration function, since the charging type refrigeration is controllable, the charging can be stopped when an ice-water mixture is formed, so as to prevent all the condensing media from becoming solid state, which is inconvenient for the user to use; in addition, in order to facilitate the use of each body part of the human body, the spherical part 102 of the ice pack body 1 is further improved so as to be capable of being deformed freely in accordance with the body part.

Ice bag the ice bag 5 ice bag.

The fabric layer 502 comprises a water-absorbing layer 5021 formed on the surface of the alloy layer 501 and a nylon layer 5022 formed on the outer surface of the water-absorbing layer 5021 and covering the whole surface of the water-absorbing layer 5021, and when the ice pack is used, the internal temperature is lower than the ambient temperature, so that air is easily contacted with the surface of the alloy layer 501 and a small amount of water drops are generated, and the problem is solved by the structural combination of the water-absorbing layer 5021 and the nylon layer 5022.

The embodiment of the utility model provides an in, the cooling medium in the cooling chamber 103 is through cooling after refrigeration piece 202 circular telegram to form gradually to ice-water mixing form or solid-state, in order to reach the controllable effect of form, ice-water mixing form more is applicable to the direct use, and solid-state is used for using when the alloy-layer 501 after artifical unable reduction deformation, and after cooling to solid-state, the accessible is placed the reuse naturally, perhaps is used for some not needing the moulding human body parts of adaptability.
