[0029] A circle of gasket 31 is formed on the inner side of the soft back panel 3, and a groove body 30 is formed between the gasket 31 and the inner side of the soft back panel 3. When the soft back panel 3 is attached to the back of the human body, the gasket 31 contacts the back of the human body, so that a sealed space is formed between the groove body 30 of the soft back panel 3 and the back of the human body. The outside of the refrigerator 4 is provided with heat dissipation holes 401 and an external air inlet 402 connected to the outside world, and the inside of the refrigerator 4 is provided with a cold air outlet 403 and a cooling cycle air inlet 404, and the cold air outlet 403 and the cooling cycle air inlet 404 are exposed in the groove body 30. When the utility model is in use, the soft back plate 3 is fixed on clothes (such as a vest, etc.). After the soft back plate 3 is attached to the clothes on the back of the human body, the gasket 31 contacts the back of the human body, so that a sealed space is formed between the groove body 30 of the soft back plate 3 and the back of the human body. Since the soft back plate 3 is made of soft material, it contacts the human body more closely and can form a more effective sealed space; the refrigerator 4 works, and external air is drawn in through the external air inlet 402 to form an airflow. The refrigerator 4 cools and discharges the cold air through the cold air outlet 403 to the sealed space, so as to cool and dissipate the heat of the back, so that the back feels cool; the refrigerator 4 discharges the hot air generated by it to the outside through the heat dissipation holes 401 to ensure the cooling effect of the refrigerator 4. At the same time, the refrigerator 4 also draws the cold air in the sealed space through the cooling cycle air inlet 404, and enters the refrigerator 4 again, thereby realizing true circulation cooling, making the back of the human body feel more comfortable, and is particularly suitable for use in the vest worn by environmental protection workers.

[0030] Among them, the outer periphery of the soft back panel 3 is provided with a connecting port 300 for connecting with clothes, and the clothes are provided with straps, which pass through the connecting port 300 and are knotted and fixed, so that the soft back panel 3 is fixedly connected to the clothes. Of course, a mother buckle and a child buckle can be respectively provided on the soft back panel 3 and the clothes, and the mother buckle and the child buckle constitute snaps, so that the soft back panel 3 is fixedly connected to the clothes; a Velcro fur surface and a Velcro hook surface can also be respectively provided on the soft back panel 3 and the clothes, so that the Velcro fur surface and the Velcro hook surface are fitted and fixed to form Velcro, thereby fixing the soft back panel 3 to the clothes.

[0031] The assembly structure of the soft back panel 3 and the refrigerator 4 is as follows: a mounting port 32 is provided on the soft back panel 3, and a first step groove 321 and a second step position 322 are respectively provided at the front and rear ends of the mounting port 32, the outer periphery of the refrigerator 4 is fitted and installed at the first step groove 321, and the buckle frame 5 is fitted and installed at the second step position 322, and the buckle frame 5 is fixed to the refrigerator 4 by buckling, so as to be clamped and fixed with the inner edge of the mounting port 32, and the assembly structure is simple, and it is ensured that the refrigerator 4 can be stably installed on the soft back panel 3, and the assembly is extremely stable.

[0032] Specifically, the inner edge of the installation opening 32 is provided with a plurality of make-away openings 323 that pass through the first step groove 321 and the second step position 322; the refrigerator 4 is provided with a plurality of card slots 405; the buckle frame 5 is provided with a plurality of undercuts 51, and the undercuts 51 pass through the make-away openings 323 and are fixed with the card slots 405. The assembly structure is extremely simple, and due to the setting of the make-away openings 323, the clamping area of ​​the buckle frame 5 and the refrigerator 4 with the inner edge of the installation opening 32 can be larger, and the assembly structure is more stable.

[0033] In addition, after the outer periphery of the refrigerator 4 is fitted and installed in the first stepped groove 321 , they can be glued together, thereby further ensuring the stability of the assembly structure.

[0034] The inner side of the soft back panel 3 is formed with a plurality of support pads 33, which are located in the gasket 31 and have the same height as the gasket 31. The support pads 33 also contact the back of the human body, thereby ensuring that the soft back panel 3 will not collapse and ensuring the size of the sealed space, thereby improving the cooling effect.

[0035] The inner side of the refrigerator 4 is also provided with a support bar 406 for raising the inner side of the refrigerator 4 to prevent the cold air outlet 403 and / or the cooling cycle air inlet 404 from being blocked.

[0036] There are two refrigerators 4 , which are symmetrically mounted on the soft back plate 3 and located in the gasket 31 , and have a better cooling effect, making the human body feel more comfortable.

[0037] The structure of the refrigerator 4 is described in detail below.

[0038] The refrigerator 4 includes: a shell 41, in which an air inlet chamber 411 is formed, and an external air inlet 402 and a cooling cycle air inlet 404 are both connected to the air inlet chamber 411; a TEC refrigeration module 42, which includes a TEC refrigeration plate 421, a cooling seat 422 arranged on the cold surface of the TEC refrigeration plate 421, and a heat dissipation seat 423 arranged on the hot surface of the TEC refrigeration plate 421; a fan 100, which is installed in the air inlet chamber 411, and the fan 100 is installed in cooperation with the TEC refrigeration module 42. The air outlet 101 of the fan 100 faces the heat dissipation seat 423 and the cooling seat 422; a partition 414 is provided at the rear end of the shell 41, and the partition 414 is connected to the TEC cooling plate 421, and separates the chamber at the rear end of the shell 41 to form a heat exhaust channel 412 and a cooling channel 413, and the cooling seat 422 is placed at the entrance of the cooling channel 413; the heat dissipation seat 423 is placed at the entrance of the heat exhaust channel 412; the heat dissipation hole 401 is connected to the heat exhaust channel 412, and the cold air outlet 403 is connected to the cooling channel 413.

[0039] When the refrigerator 4 is working, air is drawn into the air inlet chamber 411 from the external air inlet 402 and the cooling cycle air inlet 404 by the fan 100, and forms an airflow that blows toward the heat sink 423 and the cold conduction seat 422 of the TEC refrigeration module 42 through the air outlet 101. The TEC refrigeration plate 421 of the TEC refrigeration module 42 works, so that the airflow passing through the cold conduction seat 422 is cooled to form cold air, and is discharged from the cold air outlet 403 to the closed space after passing through the refrigeration channel 413, and the airflow passing through the heat sink 423 forms hot air, and is discharged from the heat dissipation hole 401 after passing through the heat exhaust channel 412, thereby ensuring the cooling effect.

[0040] The housing 41 includes a first shell 415 and a second shell 416 that are fixed together by buckles.

[0041] The fan 100 includes a housing 1, a motor installed in the housing 1, and a turbine blade 2 installed in the motor. An air outlet 101 is arranged on the outside of the housing 1. The air outlet 101 is distributed on the outside of the turbine blade 2. The housing 1 is provided with a first air inlet 102 corresponding to the cooling cycle air inlet 404. The housing 1 is also provided with a second air inlet 103 corresponding to the external air inlet 402. The upper and lower ends of the turbine blade 2 are respectively placed between the first air inlet 102 and the second air inlet 103. When the fan 100 is working, the motor drives the turbine blade 2 to rotate. During the rotation process, the turbine blade 2 will draw air from the outside to the inside in two directions through the first air inlet 102 and the second air inlet 103, so that the external air flows into the inside of the housing 1 and is discharged through the air outlet 101 to form an airflow. Since the first air inlet 102 and the second air inlet 103 draw air from the outside to the inside in two directions, the air intake is large, and the air outlet can be enhanced at the same time to meet the use requirements of high air volume. At the same time, since the first air inlet 102 and the second air inlet 103 draw air from the outside to the inside in two directions, it can meet the use requirements of two-way air intake, and is particularly suitable for the exhaust of the external air inlet 402 and the cooling cycle air inlet 404, wherein the air drawn in from the cooling cycle air inlet 404 is blown toward the cooling seat 422 only through the first air inlet 102, so that it can be converted into cold air with a lower temperature.

[0042] The turbine blade 2 includes a hub 21 assembled with a motor and a plurality of blades 22 integrally formed on the periphery of the hub 21 and spaced apart. A partition 23 is integrally connected between the middle parts of two adjacent blades 22 to separate the blades 22 into a first sheet 221 and a second sheet 222. A first airflow channel 201 corresponding to the first air inlet 102 is formed between the two adjacent first sheets 221. The first airflow channel 201 also corresponds to the cold conduction seat 422. A second airflow channel 202 corresponding to the second air inlet 103 is formed between the two adjacent second sheets 222. The flow channel 202 corresponds to the heat sink 423; specifically, during operation, when the turbine fan blade 2 is rotating, the lower first sheet 221 draws air from the first air inlet 102, and the air is discharged from the air outlet 101 after passing through the first air flow channel 201. At the same time, the upper second sheet 222 draws air from the second air inlet 103, and the air is also discharged from the air outlet 101 after passing through the second air flow channel 202. At this time, the air intake volumes of the first air inlet 102 and the second air inlet 103 can be made the same, so as to meet the use requirement that the air intake volumes of the first air inlet 102 and the second air inlet 103 be the same.

[0043] The inner side of the partition 23 is integrally connected to the outer periphery of the hub 21, and the outer side of the partition 23 extends to the outer end of the blade 22. The structure is extremely stable and connects all the blades 22 together, ensuring that the entire turbine blade structure is more stable, has high strength, and has a long service life.

[0044] The outer end of the blade 22 has a larger size than the inner end.

[0045] The blades 22 are vertically distributed on the periphery of the hub 21 , and the cross section of the blades 22 is arc-shaped.

[0046] The shell 1 includes a bottom shell 11 and an upper cover 12 which are interlocked and fixed together. The motor is installed on the bottom shell 11 and is located below the upper cover 12. The second air inlet 103 is arranged on the upper cover 12. The first air inlet 102 is arranged at the bottom of the bottom shell 11. The air outlet 101 is arranged on the sides of the bottom shell 11 and the upper cover 12.

[0047] In summary, when the utility model is in use, the soft backboard 3 is fixed on the clothes (such as a vest, etc.). After the soft backboard 3 is attached to the clothes on the back of the human body, the gasket 31 contacts the back of the human body, so that a sealed space is formed between the groove body 30 of the soft backboard 3 and the back of the human body. Since the soft backboard 3 is made of soft material, it is in closer contact with the human body and can form a more effective sealed space; the refrigerator 4 works, and the external air is drawn in through the external air inlet 402 to form an airflow. The refrigerator 4 cools and discharges the cooling air through the cold air outlet 403 to the sealed space, so as to cool the back and dissipate the heat; the refrigerator 4 discharges the hot air generated by it to the outside through the heat dissipation hole 401 to ensure the cooling effect of the refrigerator 4. At the same time, the refrigerator 4 also draws the cooling air in the sealed space through the cooling cycle air inlet 404, and enters the refrigerator 4 again, thereby realizing true circulation cooling, making the back of the human body feel more comfortable, and is particularly suitable for use in the vest worn by environmental protection workers.
