It should be noted here that the mask body 1 is made of an environmentally friendly and nontoxic composite modified plastic with low specific gravity, good heat insulation, high strength, low elastic deformation, and ensures the wearing comfort of the user and the effective performance of the cold compress function.

In some embodiments, as shown in FIG. 5, the mask body 1 includes a first baffle 15. The first partition 15 is provided vertically in the first inner chamber, and divides the first inner chamber into a plurality of first accommodation chambers 13. The cold storage bags 8 correspond to the first accommodating cavities 13 in number and are respectively accommodated in the first accommodating cavities 13. The preferred layout is: the first partition plates 15 are two in number and vertically cross each other, and the first accommodating cavities 13 are four in number; the first partition 15 and the first accommodating chamber 13 cooperate to form a "tian" layout.

In some embodiments, the rear face of the blanking cap 7 is provided with a plurality of first clearance heads 73; the closure 7 is skin fitted directly to the cheek region 100 by means of the first gap head 73 and forms a first gap zone M between the closure 7 and the cheek region 100. The preferred layout mode here is that the number of the first gap heads 73 is 5 in total, and a five-point layout mode that one is arranged in the middle of the back of the blocking cover 7 and one is arranged around the blocking cover is adopted. The first gap heads 73 positioned on the periphery are right opposite to the lower part of the cold accumulation bag 8; the first gap head 73 located at the middle is just below the intersection of the two first partition plates 15. Such design is considered blanking cover 7 and adopts the silica gel design, and the material is softer, simultaneously because first clearance area M's existence, sinks for rocking of preventing 8 in-use cold-storage bag, makes 7 backs of blanking cover directly laminate human face and causes the discomfort, so adopts the mode of this "five dot overall arrangement", effectively supports cold-storage bag 8 and prevents to sink, also prevents that first clearance area M from becoming invalid. Wherein, first clearance area M's the purpose of setting is in order to form an air area between blanking cover 7 and human cheek district 100, when cold-storage bag 8 and cheek district 100 skin carried out the heat exchange, the cold air of cold-storage bag 8 release and the heat of cheek district 100 release all reached first clearance area M, carry out the heat at first clearance area M and synthesize, first clearance area M just has played the cushioning effect, make the heat exchange overshoot obtain the buffering and softer, further avoid the uncomfortable of the cheek district 100 rapid cooling that cold-storage bag 8 heat absorption brought too fast to feel, and then it is long when improving cold-storage bag 8 single use.

Like this, the air that is in first clearance area M can be in proper order through first through-hole 72, first bleeder vent 12 and the external air of the face concrete 1 and replace, has strengthened the gas permeability when face mask portion B wears, and the result of use is better, and the partly heat that cheek district 100 produced simultaneously does not discharge to the external world through cold-storage bag 8 heat exchange through first clearance area M, first through-hole 72 and first bleeder vent 12 between, and the time is long for the single use of cold-storage bag 8 is further improved.

Further, as a preferable embodiment of the present embodiment, as shown in fig. 8 and 9, the mask body 1 further includes a first insulating layer 14; the first heat insulation layer 14 is made of a heat insulation material, and is uniformly covered on the cavity surface of the first accommodating cavity 13 by using tinfoil paper or a composite film, for example. The purpose of this is to greatly reduce the possibility of heat exchange between the cool storage bag 8 and the outside, so that the cool storage bag 8 can dissipate the cool air in the cheek area 100 of the human body as much as possible. It should be noted here that the first thermal insulation layer 14 is matched with the first ventilation hole 12, and the use of the first through hole 72 and the first gap zone M is a bright point in the present application, because the traditional design mode, ventilation property and thermal insulation are two contradictory designs, thermal insulation will certainly need good sealing effect, and complete sealing is impossible, the present application adopts the first thermal insulation layer 14 to cover the cavity surface of the first accommodating cavity 13, and intentionally guides cold air emitted from the cold storage bag 8 to enter the first gap zone M through the blocking cover 7 to exchange heat with heat emitted from the cheek area 100, and simultaneously air in the first gap zone M can flow and pass through the first through hole 72 and the first ventilation hole 12 to reach the outside, and exchange with outside air, thereby ensuring ventilation property in use, and it can be seen that no matter the cold storage bag 8 exchanges heat with the cheek area 100, or the first gap zone M exchanges air with the outside, because the arrangement mode of the first heat insulation layer 14 does not produce the loss of cold air, the air permeability is ensured while the heat insulation is realized, and the two purposes are achieved. It should be noted that the diameter of the first through hole 72 should be larger than the first venting hole 12 and smaller than the width of the first partition 15, so that air can effectively enter the first venting hole 12 through the first through hole 72, and the air entering the first through hole 72 will not flow back to the first accommodating cavity 13 due to the blocking of the first partition 15.

In some embodiments, as shown in fig. 1 and 10, a helmet portion a can be further added to cooperate with a mask portion B to achieve overall cooling of the head of the human body. The helmet portion a is worn on the human head-wearing region 300 and is located above the mask portion B.
