Summary of the invention

[0003] In order to solve the problems existing in the prior art, the present invention provides a physical cooling clothing, which can effectively reduce the heat exchange between water and the outside world during the heat exchange between water and the human body, improve the cooling effect, and reduce the energy consumed in the water cooling process.

[0004] The technical solution adopted by the present invention is:

[0005] A physical cooling suit comprises a cooling suit body, wherein a cooling water channel is arranged on the cooling suit body, the cooling water channel is located on the outside of the cooling suit body, an outer protective layer is also arranged on the outside of the cooling water channel, the outer protective layer and the cooling suit body wrap the cooling water channel, an insulating space is formed between the outer protective layer and the cooling water channel, the insulating space is filled with air, the air pressure in the insulating space is greater than the atmospheric pressure, the outer protective layer has two layers, the two layers of the outer protective layers are stacked on each other, the cross-section of the cooling water channel is semicircular, and the plane of the cooling water channel is in contact with the outer side of the cooling suit body.

[0006] Preferably, the two outer protective layers are respectively a first outer protective layer and a second outer protective layer, the first outer protective layer is located on the outside of the second outer protective layer, the first outer protective layer is connected to the cooling suit body, and the second outer protective layer is not connected to the cooling suit body and the first outer protective layer.

[0007] Furthermore, the number of the first outer protective layer and the number of the second outer protective layer are both several, and the corresponding first outer protective layer and the second outer protective layer constitute a protective layer group, and the several protective layer groups are sequentially arranged on the cooling water channel and completely cover the entire cooling water channel as a whole.

[0008] Furthermore, a reflective layer is provided on the inner side of the first outer protective layer.

[0009] Preferably, the cooling water channel is composed of a plurality of water channel units, and the plurality of water channel units are connected in sequence to form the cooling water channel. The water channel unit is a hexagonal annular water channel, and two adjacent annular water channels share the same water channel edge.

The ventilation duct can blow out wind, which can accelerate the evaporation of sweat, so that the body is in a dry state, making the user more comfortable; secondly, when the water temperature in the cooling waterway is high, the cooling purpose cannot be effectively achieved. Therefore, at this time, cool air can be blown out through the ventilation duct, which can also achieve the purpose of cooling the body; finally, the gas blown out by the ventilation duct has a weak impact on the body, which can stimulate the acupuncture points of the human body and achieve the purpose of massage.

[0027] See also Figure 1-Figure 8 The present invention provides a physical cooling suit, including a cooling suit body 1. When in use, the cooling suit body 1 is worn on the body. A cooling water channel 2 is provided on the cooling suit body 1. The cooling water channel 2 is wrapped around the outer side of the cooling suit body 1 as a whole. Usually, both ends of the cooling water channel 2 are respectively connected to a water tank, and the cool water in the water tank flows in the cooling water channel 2. The cool water in the cooling water channel 2 will exchange heat with the human body, thereby taking away the heat from the human body and achieving the purpose of cooling.

[0028] In order to improve the cooling effect and reduce the absorption of external heat by the water flow in the cooling waterway 2, the present invention makes the following improvements:

[0029] Set up outer sheath

[0030] An outer protective layer is arranged on the outside of the cooling water channel 2, and the outer protective layer and the cooling suit body 1 wrap the entire cooling water channel 2. An insulating space 5 is formed between the outer protective layer and the cooling water channel 2, and the insulating space 5 is filled with air (the insulating space 5 is a closed space), and the air pressure in the insulating space 5 is greater than the external atmospheric pressure (ensuring that the insulating space 5 is in a bloated state).

[0031] Simply put, at any cross section, from outside to inside are respectively the outer protective layer, the thermal insulation space 5, the cooling water channel 2, and the cooling suit body 1, and cool water flows in the cooling water channel 2, so the cool water can exchange heat with the human body through the cooling suit body 1. When the cool water exchanges heat with the outside world, the heat from the outside world must pass through the thermal insulation space 5, and the air in the thermal insulation space 5 cannot convect with the air from the outside world, so this greatly slows down the entry of heat from the outside, thereby reducing the water flow absorbing the heat from the outside, preventing the temperature of the water flow from rising too quickly, and thus ensuring the cooling effect on the human body.

[0032] Since the present invention needs to be worn on a person during use, the outer protective layer usually needs to be made of soft materials. During use, sharp objects may pierce the outer protective layer, thereby reducing the thermal insulation effect of the outer protective layer.

[0033] To solve this problem, the number of outer sheath layers used in the present invention is two, and the two outer sheath layers are stacked. The outer one is the first outer sheath layer 3, and the inner one is the second outer sheath layer 4.

[0034] Under normal circumstances, only the first outer sheath 3 will be punctured (see Figure 3 ), when the first outer sheath 3 is punctured, a small hole 6 is formed on the first outer sheath 3 (see Figure 4 ), since the air pressure in the insulation space 5 is relatively high, the second outer protective layer 4 will be pushed outward, so that the second outer protective layer 4 blocks the small hole 6, thereby preventing air leakage and ensuring the insulation effect of the insulation space 5.

[0035] The cross-section of the cooling water channel 2 is semicircular, and the side of the cooling water channel 2 that is in contact with the cooling suit body 1 is a straight side of the semicircle, while the side corresponding to the outer protective layer is semicircular, so the outer protective layer should also be semicircular, and the center of the semicircular circle of the outer protective layer is at the same point as the center of the semicircular circle of the cooling water channel 2, and the radius of the semicircular circle of the outer protective layer is larger than the radius of the semicircular circle of the cooling water channel 2, so that it can be ensured that the outer protective layer can just separate the cooling water channel 2 from the outside world.

[0036] The inventors consider that when a sharp object pierces the first outer protective layer 3, if the sharp object continues to pierce downward, it is still possible to pierce the second outer protective layer 4, thereby causing the air in the thermal insulation space 5 to leak out, reducing the thermal insulation effect.

[0037] In order to solve this problem, the present invention also makes the following improvements:

[0038] The first outer sheath 3 is connected to the cooling suit body 1 (fixed connection), and the second outer sheath 4 is not connected to the cooling suit body 1 and the first outer sheath 3. In simple terms, the second outer sheath 4 is just stuck in the first outer sheath 3. When a sharp object contacts the second outer sheath 4, since the second outer sheath 4 is not fixed, the second outer sheath 4 has a larger space for movement, and the second outer sheath 4 is more likely to deform (see Figure 5 ), thereby reducing the probability of the second outer sheath 4 being punctured.

[0039] Of course, even according to the above configuration, the first outer sheath 3 and the second outer sheath 4 may still be punctured at the same time, in order to reduce the influence of the first outer sheath 3 and the second outer sheath 4 being punctured at the same time on the thermal insulation effect.

[0040] The number of the first outer sheath 3 and the number of the second outer sheath 4 are both several, and the corresponding first outer sheath 3 and second outer sheath 4 constitute a sheath group 7, so there are several sheath groups 7, and these sheath groups 7 are arranged in sequence and closely along the cooling waterway 2, so as to completely cover the entire cooling waterway 2. The insulation space 5 in each sheath group 7 is relatively independent, so when one or several sheath groups 7 are punctured, it will not affect the insulation effect of other sheath groups 7, so the heat absorbed by the entire cooling waterway 2 is relatively limited, thereby reducing the impact on the water temperature in the cooling waterway 2.

[0041] In practical applications, the size of the protective layer group 7 (projected area on the cooling suit body 1) should be controlled within 1-3 cm 2 .

[0042] A reflective layer is arranged on the inner side of the first outer protective layer 3, and the purpose of the reflective layer is to prevent external light radiation from entering the cooling waterway 2 and to prevent external heat radiation from entering the cooling waterway 2. It also has a certain heat preservation effect.

[0043] The cooling water channel 2 is composed of a plurality of water channel units, which are connected in sequence to form the cooling water channel 2. A single water channel unit is a hexagonal annular water channel, and two adjacent annular water channels (two annular water channels connected to each other) share the same water channel edge.

[0044] The shape of the circular waterway is a regular hexagon, and water can flow along the six sides of the regular hexagon.

[0045] The use of an annular water channel can relatively expand the flow rate of the cooling water channel 2, and compared with a single water channel, blocking a channel on one side of the annular water channel does not hinder the free flow of water in the cooling water channel 2.

[0046] A ventilation duct 8 is also provided on the cooling suit body 1. The ventilation duct 8 is arranged on the outside of the cooling suit body 1. The ventilation duct 8 is arranged beside the cooling water channel 2 along the direction of the cooling water channel 2, and the ventilation duct 8 and the cooling water channel 2 do not cross each other. A plurality of ventilation holes are opened on the cooling suit body 1, and these ventilation holes are connected with the ventilation duct 8, and these ventilation holes are evenly distributed along the ventilation duct 8.

[0047] Simply put, after people put on the physical cooling suit, due to the poor air permeability of the physical cooling suit itself, the sweat on the body cannot be effectively discharged, and the gas can be blown up through the ventilation duct 8 and directly act on the body through the vent, thereby accelerating the evaporation of sweat and making the body in a relatively dry state; in addition, when the cooling water channel 2 cannot effectively cool the body, the cool air can be blown out through the ventilation duct 8, which can also achieve the purpose of cooling and solve emergencies; finally, the gas blown out by the ventilation duct 8 has a weak impact on the body, which can stimulate the acupuncture points of the human body and achieve the purpose of massage.

[0048] Of course, a skin-friendly layer (cloth, etc.) can be laid on the inner side of the cooling suit body 1 (the side in direct contact with the body) to increase the comfort of the human body wearing the physical cooling suit.

[0049] The cooling suit body 1 may be provided with a semi-annular pipe, and the cooling water channel 2 is formed between the semi-annular pipe and the cooling suit body 1 .

[0050] The two ends of the cooling water channel 2 are respectively a water inlet and a water outlet.
