Referring to fig. 1 to 4, the present invention discloses a fire fighting vortex tube vest, which comprises a vest 1, a vortex tube 2, and a compressed air source 3.

Referring to fig. 1, the vest 1 includes a body 11 and a first pipeline 12 disposed in the body 11. The body 11 is of a double-layer structure, and the first pipeline 12 is fixedly arranged between the double-layer structures of the body 11. Specifically, the body 11 is provided with an inner layer 111 and an outer layer 112, the inner layer 111 is closer to the human body than the outer layer 112, and the inner layer 111 is made of a fabric material capable of absorbing sweat, so that the comfort level can be improved while the fire rescue worker can quickly exchange heat when wearing the body, discomfort of the body caused by air impermeability of clothes can be reduced, and the working efficiency can be improved.

Referring to fig. 2, a first pipeline 12 is disposed between the inner layer 111 and the outer layer 112. The first pipeline 12 includes a plurality of pipeline main body portions 121 arranged in parallel, and a bending portion 122 connected between two adjacent pipeline main body portions 121, and the pipeline main body portions 121 all extend along a first direction D1. In another embodiment, the pipe body 121 extends in a second direction D2 perpendicular to the first direction D1. The first pipe 12 is arranged in a serpentine shape. Specifically, the first pipe 12 is a hollow metal pipe, and the pipe body 121 and the bent portion 122 are integrally bent to allow gas to flow therethrough. Because the pipeline of metal material is the easier heat transfer than the pipeline of other materials, from this, the fire rescue personnel can obviously feel intensification or cooling when using. In the present embodiment, the first pipeline 12 is disposed on a front surface of the body 11, which is a surface facing a front of a human body of the firefighter. In other embodiments, the first pipeline 12 is disposed on a back surface of the body 11, and the back surface is a surface facing the back of the person of the rescue worker. In the third embodiment, the first pipe 12 is disposed on both the front and back sides of the body 11, which can further accelerate heat exchange.

Referring to fig. 1 to 2, one end of the first pipeline 12 is provided with a first connector 13, and the other end of the first pipeline 12 is provided with a first switch 14. The first switch 14 is used for adjusting the airflow rate in the first pipeline 12, so that the vest 1 can adjust the temperature rising or falling speed according to the needs of the fire-fighting and rescue workers, and the needs of the fire-fighting and rescue workers in different environments can be met. In addition, the fire-fighting rescue personnel need wear the fire-fighting protective clothing outside the fire-fighting vortex tube vest, and after the first switch 14 is turned on, the air flow discharged from the first interface 13 can flow to other areas of the human body due to the fact that the fire-fighting protective clothing has a certain isolation effect on the external environment, and therefore the comfort of the fire-fighting rescue personnel is further improved.

Referring to fig. 4, the vortex tube 2 includes a first air outlet 21 disposed at one end, a second air outlet 22 disposed at the other end of the vortex tube 2, and a first air inlet 24 disposed on a wall 23 of the vortex tube 2. The first port 13 is selectively connected to the first air outlet 21 or the second air outlet 22. The compressed air source 3 has a housing 34, and a third air outlet 31 disposed at the bottom of the housing 34. The third outlet 31 is connected to the first inlet 24 via a second line 32. A second switch 33 is arranged at the third air outlet 31 of the compressed air source 3. The second switch 33 is connected to the vortex tube 2 via the second line 32. The first air outlet 21 or the second air outlet 22 of the vortex tube 2 is connected with the first port 13 through a third pipeline (not shown). Specifically, when the fire rescue personnel carries out an emergency, the fire rescue personnel wear the fire fighting vortex tube vest and then turn on the second switch 33, and the compressed air flow in the compressed air source 3 sequentially flows into the vortex tube 2 through the second pipeline 32 and the first air inlet 24. At this time, the high-speed airflow generates vortex in the vortex tube 2 to separate cold and hot airflows. The cold air flow flows out of the first air outlet 21, and the hot air flow flows out of the second air outlet 22. When the external environment temperature is high, the body temperature of the fire rescue personnel is high, the fire rescue personnel respectively communicate the two ends of the third pipeline with the first air outlet 21 and the first interface 13, at the moment, the cold air flow flowing into the first pipeline 12 can rapidly reduce the body surface temperature of the fire rescue personnel.

When the external environment temperature is lower than the body temperature of the fire rescue worker, the fire rescue worker respectively communicates the two ends of the third pipeline with the second air outlet 22 and the first interface 13. At this time, the body surface temperature of the fire rescue personnel can be rapidly raised by the hot air flow flowing into the first pipeline 12.

Referring to fig. 1, in other embodiments, a temperature controller 5 is further disposed in the body 11, and the temperature controller 5, the first switch 14 and the second switch 33 are electrically connected. The temperature controller 5 can monitor the body surface temperature of the fire rescue workers in real time, and when the body temperature is higher than or lower than the preset temperature of the temperature controller 5, the fire fighting vortex tube vest can be automatically opened, so that the safety of the fire rescue workers is guaranteed.

The utility model discloses fire control vortex undershirt tests at indoor 17 degrees centigrade, after lasting stable air feed, the temperature of first gas outlet 21 is 4 degrees centigrade, the temperature of second gas outlet 22 is 24.4 degrees centigrade, can cool down or heat up to fire control rescue personnel body surface rapidly.

Utilize the control variable method, two tests are done to same compressed air source 3 same pressure, are opening the compressed air source of 6.8 liters as the tester and carry out the air feed, work as the gas temperature of first gas outlet 21 reaches 4 degrees centigrade and the gas temperature of second gas outlet 22 reaches 24.4 degrees centigrade required time and is 4 minutes, closes second switch 33, compressed air source 3 pause is right first pipeline 12 air feed detects compressed air source 3's pressure drops for 11mpa for 29mpa before using. The usage time of the compressed air source 3 is 20 minutes when the tester uses only the mask breathing air without opening the second switch 33. The contrast is known that the utility model discloses the vortex vest of fire control is right compressed air source 3's live time influence is little.

To sum up, the utility model discloses fire control vortex undershirt has set up first pipeline 12 in body 11 of undershirt 1, connects pressurized air source 3 and vortex tube 2 through second pipeline 32, and the first gas outlet 21 or the second gas outlet 22 and the first air inlet 24 of rethread third tube coupling vortex tube 2. The high-speed airflow in the compressed air source 3 enters the vortex tube 2, and the cold or hot airflow separated from the high-speed vortex is conveyed into the first pipeline 12 through the third pipeline, so that the vest 1 can rapidly achieve the effect of cooling or heating.

The above embodiments are only used for illustrating the present invention and not for limiting the technical solutions described in the present invention, and the understanding of the present specification should be based on the technical personnel in the technical field, such as the descriptions of the directions of "front", "back", "left", "right", "upper", "lower", etc., and although the present specification has been described in detail with reference to the above embodiments, the ordinary technical personnel in the technical field should understand that the present invention can still be modified or substituted by the equivalent, and all the technical solutions and the modifications thereof without departing from the spirit and scope of the present invention should be covered within the scope of the claims of the present invention.
