Description

Technical Field

[0001] This invention belongs to the field of cooling clothing. Background Technology

[0002] Workers wearing active circulating cooling water suits may encounter the following two situations during operation:

[0003] In the first scenario, when the working environment is in a high-temperature and harsh condition, and the staff wearing this clothing need to work in such an environment for a long time, if they do not carry an external cold source, the cold source pocket has a limited capacity and can only hold a limited amount of ice, so a long-term cooling cycle cannot be achieved.

[0004] In the second scenario, when the working environment is in a normal high-temperature condition and the staff does not need to work continuously for a long time, carrying a bulky external cooling source would cause inconvenience in walking. Summary of the Invention

[0005] Purpose of the invention: In order to overcome the shortcomings of the existing technology, the present invention provides a circulating cooling and heat-reducing suit made of flat water pipe material, which can be compatible with both non-external cold source and external cold source situations.

[0006] Technical solution: To achieve the above objectives, the present invention provides a circulating cooling garment made of flat water pipe material, characterized in that: it includes an external cold source, a circulation switching unit, and a garment body; the inner side of the fabric of the garment body is sewn with zigzag-distributed circulating cooling pipes; the circulation switching unit includes a coupled state and a disengaged state;

[0007] When the circulation switching unit is in the connected state, the cold water outlet pipe and return pipe of the external cold source are connected to both ends of the circulating cooling pipe through the circulation switching unit in the connected state.

[0008] Furthermore, a temporary cold source pocket is provided in a certain part of the garment body, and the tube of the circulating cooling pipe passes through the location of the cold source pocket, which can accommodate the temporary cold source.

[0009] Furthermore, in the separated state, the cold water outlet pipe and return pipe of the external cold source are separated from the garment body at the circulation switching unit, and the two ends of the circulating cooling pipe are connected to each other at the circulation switching unit.

[0010] Furthermore, the circulating cooling pipe is a flat flexible pipe with a flat liquid guiding channel inside. Both sides of the flat flexible pipe have sewn strips along the length direction, which are sewn to the inside of the fabric of the garment.

[0011] Furthermore, the circulation switching unit includes a circulation pump, a female connector, and a male connector. The circulation pump and the female connector are both fixed to the garment body. The male connector is connected to the end of the cold water outlet pipe and the return pipe of the external cold source. When the male connector is inserted into the female connector, the circulation switching unit is in the connected state. When the male connector is separated from the female connector, the circulation switching unit is in the disconnected state.

[0012] Furthermore, the female connector includes a cylindrical tube, inside which a piston is coaxially and movably disposed, forming a spring cavity between the piston and the end wall of the cylindrical tube, and the male connector includes a cylindrical body.

[0013] Furthermore, in the coupled state: the column is coaxially inserted into the end of the cylinder away from the end wall, and the inserted end of the column is provided with a top head that presses against the piston; a first O-ring, a second O-ring, and a third O-ring are distributed along the axial direction outside the column; a first annular cavity is formed between the first O-ring and the second O-ring, and a second annular cavity is formed between the second O-ring and the third O-ring; a blind hole is provided on the inner wall of the cylinder at the location of the first annular cavity, and the blind hole is connected to the end of the spring cavity away from the piston through a liquid guiding channel inside the cylinder wall; the two ends of the circulating cooling pipe are end a and end b, respectively, end a is connected to the pump inlet of the circulating pump, and end b is at the end... The wall connects to the spring cavity; the pump outlet of the circulating pump connects to the second annular cavity through the pump outlet pipe fixed on the column; the outlet end of the cold water outlet pipe connects to the first annular cavity through channel a on the column, and the inlet end of the return water pipe connects to the second annular cavity through channel b on the column; a compressed spring is coaxially arranged in the spring cavity, and the compressed spring exerts a thrust on the piston along the axial direction; the piston and the end wall are connected by a loose and tortuous wire; a locking outer edge is integrally provided on the outer edge of the column away from the piston, with locking hole a on the locking outer edge, and locking hole b at one end of the column. The locking bolt locks the locking hole a and the locking hole b, thereby fixing the column.

[0014] Furthermore, in the separated state: the column body separates from the cylinder, thereby causing the male connector and the female connector to enter the separated state; in this state, after the piston loses the limit of the top, the spring in the compressed state pushes the piston along the axial direction until the originally tortuous pull line is straightened. Under the constraint of the taut pull line, the piston can no longer be pushed by the spring. At this time, the outer wall surface of the piston blocks the blind hole, and the pump outlet pipe is connected to the spring cavity.

[0015] Beneficial effects: This solution is compatible with both non-external cooling source and external cooling source scenarios.

[0016] In the first scenario, loop A is formed. The circulating cooling pipe water that flows continuously through loop A will circulate through the cold zone of the external cold source, thereby continuously cooling the staff. Since the amount of ice and other materials in the external cold source can be sufficient, it is possible to cool the staff's clothing for a long time.

[0017] In the second scenario, the present invention forms a B-cycle, in which the circulating cooling pipe water continuously flows through the cold source pocket and absorbs heat, thereby continuously cooling the workers. After the ice in the cold source pocket melts, it is refilled. In this scenario, no external cold source is involved, and it is lightweight and flexible. Attached Figure Description

[0024] The invention will now be further described with reference to the accompanying drawings.

[0025] As attached Figures 1 to 6 The illustration shows a circulating cooling suit made of flat water pipe material, such as... Figure 1 As shown, it includes an external cold source 8, a circulation switching unit 7, and the garment itself; the external cold source 8 can be a following vehicle that moves synchronously with the staff, or it can be a back-hanging structure that moves synchronously with the staff; the interior of the external cold source 8 can be filled with large-volume ice blocks or refrigeration equipment to create a low-temperature zone inside the external cold source 8. A circulating heat exchange pipe is arranged in the low-temperature zone. When the water in the circulating heat exchange pipe inside the external cold source 8 flows through the low-temperature zone inside the external cold source 8, it will be cooled down.

[0026] The inner side of the garment fabric has zigzag-distributed circulating cooling pipes 3, which are flat, flexible tubes, such as... Figure 2The flat flexible tube contains a flat liquid channel 32, and there are sewing tapes 31 along the length direction on both sides of the flat flexible tube. The sewing tapes 31 are sewn to the inside of the fabric of the garment. The flat flexible tube improves comfort. Other functions are supplemented at the end of this article.

[0027] Cyclic switching unit 7 includes an engagement state (such as...) Figure 4 ) and separation state (e.g.) Figure 5 When the circulation switching unit 7 is in the connected state, the cold water outlet pipe 1 and return water pipe 2 of the external cold source 8 are respectively connected to the two ends of the circulating cooling pipe 3 through the circulation switching unit 7 in the connected state, so that the circulating heat exchange pipe in the external cold source 8 and the circulating cooling pipe 3 are connected to each other to form a closed loop.

[0028] like Figure 1 A temporary cold source pocket 4 is provided in a certain part of the garment body, and the tube of the circulating cooling pipe 3 passes through the location of the cold source pocket 4. The cold source pocket 4 can hold a temporary cold source. The temporary cold source is an ice pack or ice cube that can be placed in the cold source pocket 4. The cold source pocket 4 is made of waterproof material.

[0029] When the cycle switching unit 7 is in the disconnected state, such as Figure 5 The cold water outlet pipe 1 and return water pipe 2 of the external cold source 8 are separated from the clothing body at the circulation switching unit 7, and the two ends of the circulating cooling pipe 3 are connected to each other at the circulation switching unit 7.

[0030] like Figure 5 The circulation switching unit 7 includes a circulation pump 11, a female connector 71, and a male connector 72. Both the circulation pump 11 and the female connector 71 are fixed to the garment body. The male connector 72 is connected to the ends of the cold water outlet pipe 1 and the return water pipe 2 of the external cold source 8. When the male connector 72 is inserted into the female connector 71, the circulation switching unit 7 is in the connected state. When the male connector 72 is separated from the female connector 71, the circulation switching unit 7 is in the separated state. The female connector 71 includes a cylindrical tube 9. A piston 23 is coaxially and movably arranged inside the cylindrical tube 9. A spring cavity 26 is formed between the piston 23 and the end wall 28 of the cylindrical tube 9. The male connector 72 includes a column body 30.

[0031] In the combined state, such as Figure 4The column 30 is coaxially inserted into the end of the column cylinder 9 away from the end wall 28. The insertion end of the column 30 is provided with a top head 24, which presses against the piston 23. A first O-ring 18, a second O-ring 20, and a third O-ring 21 are distributed along the axial direction on the outside of the column 30. A first annular cavity 17 is formed between the first O-ring 18 and the second O-ring 20, and a second annular cavity 22 is formed between the second O-ring 20 and the third O-ring 21. A blind hole 19 is provided on the inner wall of the column cylinder 9 at the location of the first annular cavity 17. The blind hole 19 is connected to the end of the spring cavity 26 away from the piston 23 through the liquid guiding channel 25 inside the wall of the column cylinder 9. The two ends of the circulating cooling pipe 3 are end a 5 and end b 6, respectively. End a 5 is connected to the pump inlet of the circulating pump 11, and end b 6 is connected to the spring cavity at the end wall 28. 26; The pumping end of the circulating pump 11 is connected to the second annular cavity 22 through the pumping pipe 10 fixed on the column 9; The outlet end of the cold water outlet pipe 1 is connected to the first annular cavity 17 through the a channel 155 on the column 30, and the inlet end of the return water pipe 2 is connected to the second annular cavity 22 through the b channel 16 on the column 30; A compressed spring 27 is coaxially arranged in the spring cavity 26, and the compressed spring 27 exerts a thrust on the piston 23 along the axial direction; The piston 23 is connected to the end wall 28 through a loose and tortuous wire 29; A locking outer edge 15 is integrally provided on the outer edge of the column 30 away from the piston 23, and a locking hole 13 is provided on the locking outer edge 15. A locking hole 14 is provided on one end of the column 9, and the locking bolt 12 locks the locking hole 13 and the locking hole 14, thereby fixing the column 30.

[0032] In the separated state, such as Figure 5 The column 30 separates from the cylinder 9, thereby separating the male connector 72 from the female connector 71. In this state, after the piston 23 loses the limit of the top 24, the spring 27 in a compressed state pushes the piston 23 along the axial direction until the originally tortuous pull line 29 is straightened. Under the constraint of the straightened pull line 29, the piston 23 can no longer be pushed by the spring 27. At this time, the outer wall surface of the piston 23 blocks the blind hole 19, and the pump outlet pipe 10 is connected to the spring cavity 26.

[0033] Working principle: In the first case, such as Figure 4When the working environment is high-temperature and harsh, and the staff wearing this clothing need to work in such an environment for a long time, the limited volume of the cold source pocket 4 means that the amount of ice that can be filled in the cold source pocket 4 is limited, which cannot achieve a long-term cooling circulation effect. In order to ensure that the staff can receive continuous cooling in the high-temperature and harsh environment for a long time, it is necessary to use an external cold source for cooling. In the external state, the circulation switching unit 7 is in the engaged state, and the locking bolt 12 locks the locking hole a 13 and the locking hole b 14. The column 30 is fixed in the column cylinder 9. At this time, driven by the circulation pump 11, the circulation path of the cooling water is as follows: the slightly cooler water from the external cold source 8 flows through: cold water outlet pipe 1, channel a. 155, First annular cavity 17, blind hole 19, liquid guiding channel 25, spring cavity 26, b end 6, circulating cooling pipe 3, a end 5, circulating pump 11, pump outlet pipe 10, second annular cavity 22, b channel 16 and finally return to the external cold source 8 through the return water pipe 2, thus forming the A cycle. The water continuously flowing through the circulating cooling pipe 3 in the A cycle will circulate through the cold area in the external cold source 8, so that the water in the circulating cooling pipe 3 will continuously cool down the staff. Since the amount of ice and other materials in the external cold source 8 can be sufficient, it can cool down the staff's clothes for a long time. However, in this case, due to the need to carry the large external cold source 8, there are also disadvantages such as inconvenience in walking and inflexibility in the working process.

[0034] The second scenario, such as Figure 5When the working environment is in a normal high-temperature condition and the staff does not need to work continuously for a long time, carrying a bulky external cold source 8 would cause inconvenience. However, the amount of ice and other cold sources stored in the cold source bag 4 is sufficient to meet the cooling and temperature reduction requirements under such circumstances. The specific working principle is as follows: After unscrewing all the locking bolts 12, the compressed spring 27 pushes the piston 23, pushing the cylinder 30 in the cylinder 9 outward, thereby separating the male connector 72 from the female connector 71. As the compressed spring 27 continues to push the piston 23 along the axial direction, the originally zigzag pull line 29 is straightened. Under the constraint of the taut pull line 29, the piston 23 can no longer be pushed by the spring 27. At this time, the outer wall of the piston 23 seals the blind hole 19, and the pump outlet pipe 10 connects to the spring cavity 26. At this time, the cold water outlet pipe 1 and return pipe 2 of the external cold source 8 are separated from the clothing body at the circulation switching unit 7. Compared with not carrying the external cold source 8, a certain amount of ice or other temporary cold sources are filled in the temporary cold source pocket 4. At this time, driven by the circulation pump 11, the circulation path of the cooling water is as follows: the water in the circulation pump 11 is pumped out from the pump outlet pipe 10 and flows through the spring cavity 26, the b end 6, the circulation cooling pipe 3 in sequence, and finally flows back to the circulation pump 11 through the a end 5, thus forming the B cycle. The water in the circulation cooling pipe 3 that flows continuously in the B cycle will circulate and flow near the cold source pocket 4 and absorb heat, so that the water in the circulation cooling pipe 3 will continuously cool the staff. After the ice in the cold source pocket 4 melts, it is refilled. This situation has the characteristics of being lightweight and flexible, but it cannot achieve long-term continuous cooling.

[0035] Supplement: During the switching between the two states described above, the volume of the spring cavity 26 will change. In this design, the circulating cooling pipe 3 is a flat, flexible pipe. Figure 2 Its internal volume can adapt to changes, and the total volume inside the circulating cooling pipe 3 is much larger than the volume of the spring cavity 26. Therefore, changes in the volume of the spring cavity 26 will not cause large changes in the internal pressure of the entire system, and thus will not affect the operation of this scheme.

[0036] The above are merely preferred embodiments of the present invention. It should be noted that those skilled in the art can make various improvements and modifications without departing from the principle of the present invention, and these improvements and modifications should also be considered within the scope of protection of the present invention.
