Description

Technical Field

[0001] The present invention relates to the field of wearable devices, and in particular to a quickly detachable active cooling suit. Background Art

[0002] People have their own isothermal zones, and in this temperature zone, they can maintain their normal body temperature by relying on physical regulation. If the ambient temperature continues to rise, the heat dissipation ability of people is blocked, and physical regulation alone can no longer maintain thermal balance. At this time, physical and chemical regulation must be initiated. When these adjustments cannot effectively maintain the thermal balance in the body, abnormal changes occur in human physiological functions, especially temperature regulation, water and salt metabolism, and blood circulation. For example, excessive sweating will increase the burden on the cardiovascular system. If the high temperature exceeds the tolerance of the human body, it will reduce work efficiency and affect judgment at the least, and cause heat stroke in severe cases, and even more serious cases will lead to sudden death. In order to solve the above problems, cooling and cold storage protective clothing came into being.

[0003] Most of the phase change cooling suits on the market use cold gel or phase change material as the cold source. This material is injected or inserted into the protective suit, and the protective suit can maintain coldness for a certain period of time after being frozen. However, the biggest disadvantage is that the gel will harden after freezing and will not fit the human body, seriously affecting the wearer's flexibility when moving. At the same time, the disassembly, assembly and cold storage of each cold storage unit before and after the use of the cooling suit is relatively cumbersome and labor-intensive. In addition, all cooling suits need to be frozen and stored in advance and cannot be used in emergencies.

[0004] In summary, there is an urgent need for an active cooling suit with good breathability and quick disassembly, which can enhance the comfort of the wearer while optimizing the disassembly, assembly, and cold storage of the cooling suit before and after use, greatly improving the work efficiency of the wearer while providing immediate cooling when used.

[0013] Furthermore, the phase change cold storage material is a polymer phase change cold storage material that can store cold and remains flexible after freezing. The material can still stretch, bend, twist and deform without losing performance after freezing. Specifically, it is a mixture of one or more of sodium polyacrylate, polyethylene glycol, isocyanate, carboxymethyl cellulose, sodium carboxymethyl cellulose, expanded graphite and calcium chloride hexahydrate.

People familiar with the art can easily understand other advantages and effects of the present invention from the contents disclosed in this specification. Obviously, the described embodiments are part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative achievements are within the scope of protection of the present invention.

[0021] The cooling clothing body (6) is formed by bonding an outer heat-insulating, cold-locking and breathable layer (1) and an inner active cold-storing and cooling layer (4); the active cold-storing and cooling layer is composed of a cold-storing phase-change cold-storing material (2) and a spontaneous heat-absorbing and cooling material; at the same time, a Velcro circular fur surface (i.e., a hook surface) (5) is provided at a portion of the heat-insulating and cold-locking layer facing the human body, and each cold-storing unit is provided with a Velcro quilled surface (i.e., a fur surface) (10) corresponding to the Velcro on the heat-insulating and cold-locking layer on the side facing the heat-insulating and cold-locking layer; the cold-storing unit and the heat-insulating and cold-locking layer can be quickly bonded and disassembled by the Velcro, so that the active cold-storing and cooling layer (4) and the heat-insulating and cold-locking layer (6) can be separated as a whole.

[0022] The heat-insulating and cold-locking layer (1) is made of a breathable fabric with a relatively low thermal conductivity, specifically aerogel felt.

[0023] Compared with traditional materials, aerogel can achieve better results with lighter weight and smaller volume. Aerogel has the advantages of heat insulation and high temperature resistance. The use of aerogel coating can effectively prevent the entry of external heat and the loss of internal coolness, thereby extending the cooling time.

[0024] The cooling suit body (6) is of an integrated type, and the cooling suit side waist (7) is made of elastic and wear-resistant fabric, specifically made of high-strength vinylon fiber.

[0025] The quick-detachable active cooling clothing is provided with three active cold storage and cooling layers (4) on the side close to the human body in the heat-insulating, cold-locking and breathable layer, two of which are located on the left and right sides of the front of the human body's upper torso, and one active cold storage and cooling layer is located behind the human body's upper torso (back).

[0026] The active cold storage and cooling layer is composed of a cold-storage phase change cold storage material (2) and a spontaneous heat absorption and cooling material (8) (9) which are nested in outer and inner layers.

[0027] The spontaneous heat absorption and cooling materials (8) and (9) are mutually soluble and can absorb heat and cool down. The material (8) is specifically a mixture of carbonamide and ammonium chloride; the material (9) is a mixture of water and glycerol. The material (9) is packaged with fragile plastic, and the active cold storage and cooling layer can be squeezed hard when in use.

[0028] The active cold storage and cooling layer (4) is composed of 2-4 sheet-like cold storage units, and adjacent sheet-like cold storage units are connected by splicing fabrics, and the fabrics are connected to the edges of the sheet-like cold storage units, wherein the spliced ​​fabrics are made of one or more of nylon, natural cotton, polyester, etc.

[0029] The active cold storage and temperature reduction layer (4) is composed of a packaging bag (3) with excellent mechanical properties, stable chemical properties and good cold insulation, and a phase change cold storage material (2) placed inside the packaging bag, wherein the packaging material is specifically made of polyethylene.

[0030] The phase-change cold storage material (2) is a polymer phase-change cold storage material that can store cold and remains flexible after being frozen. The material can still be stretched, bent, twisted and deformed without losing performance after being frozen. Specifically, it is a mixture of sodium polyacrylate, polyethylene glycol, isocyanate, carboxymethyl cellulose, sodium carboxymethyl cellulose, expanded graphite and calcium chloride hexahydrate.

[0031] Since the spine is one of the most important organs of the human body, the present invention can prevent the phase change cold storage material from acting on the spine and avoid harm to the body by splicing a large number of cold storage units. At the same time, compared with products on the market, most of which require cold storage in advance, the present invention utilizes the principle of dissolution heat absorption and phase change material energy storage to achieve the effect of instant cooling. At the same time, the excess cold will be absorbed by the phase change cold storage material to extend the cooling time.

[0032] The flexible phase-change cold storage material also makes it possible for the phase-change cold storage material to completely fit the human body after energy storage, and the invention adopts a large-area detachable type, which is convenient for cleaning and installation before and after use, and can achieve the effect of continuous use by quickly replacing the active cold storage and cooling layer (4).
