Claims (1)

[Scope of claims for utility model registration] 1. Consists of a refrigerant condensing unit and a cold air generation unit,
The cold air generation unit includes an insulating case forming a cooling chamber, an air cooler installed in the case and for cooling air, and transparently installed in the insulating case so as to correspond to both ends of the cooling chamber. an inlet pipe connected to one of the two passages and for introducing air into the cooling chamber; and an introduction pipe connected to the other passage for leading out the cooled air from the cooling chamber and injecting it to the human body. 1. A cryogenic air treatment device comprising a lead-out pipe, and a switching mechanism for switching the positions of the two pipes is provided between the heat insulating case and the lead-in pipe and the lead-out pipe. 2 A pair of first and second cooling chambers that communicate with each other at the bottom are formed inside the heat insulating case, and two passages are formed in the heat insulating case that communicate with the ends of the two cooling chambers, respectively. , the switching mechanism is supported so as to be liftable and reversible by 180 degrees with respect to the passage forming surface of the heat insulating case, and further includes a switching arm urged toward the passage forming surface by a spring, and a switching arm that is biased toward the passage forming surface by a spring; 2
2. The cryogenic air treatment device according to claim 1, which is formed by a mounting ring that is fixed in correspondence with each of the two passages and that can fit and fix the inlet pipe and the outlet pipe. 3. The air cooler is formed by a large number of cooling fins arranged in parallel with each other and a plurality of thin tubes passing through them in a zigzag shape, and a plurality of the coolers are stacked in the cooling chamber, and each air cooling A request for registration of a utility model in which a baffle plate is interposed between the cooling fins and has the function of changing the flow of air in a direction perpendicular to the slits of the cooling fins to uniformly supply air to each of the slits. The cryogenic wind treatment device according to item 1. 4 A refrigerant liquid pipe for sending refrigerant liquid from a refrigerant condensing unit is branched and connected to the air cooler housed in the first and second cooling chambers, and a solenoid valve for refrigerant liquid switching is installed in the branch pipe part. and a refrigerant expansion valve are respectively connected to the refrigerant expansion valve, and a pressure equalizing pipe is connected to the refrigerant expansion valve for sending refrigerant gas to the refrigerant gas pipe when the internal pressure of the thin tube of the air cooler suddenly increases. The cryogenic air treatment device according to item 2. 5. The cryogenic air treatment device according to claim 1, wherein the air cooler is cooled to -30 to -60 degrees. 6. The cryogenic air treatment device according to claim 4, wherein the refrigerant gas pipe has a check valve for preventing backflow into the thin pipe.
