Description

Technical Field

[0001] This application relates to the technical field of outdoor clothing, and particularly to a cooling garment. Background Art

[0002] Traditional bee-proof clothing needs to seal the openings of the trouser legs, sleeves and head to resist bee stings, forming a closed space inside the clothing. Generally, thick fabrics are used, resulting in poor air permeability. In a high-temperature working environment in summer, due to poor air permeability, such clothing is likely to form an internal heat accumulation environment, hindering the evaporation and heat dissipation of human sweat, with very poor wearing comfort, and is prone to heatstroke after long-term wearing. Summary of the Invention

[0003] Based on this, it is necessary to provide a cooling garment that can improve wearing comfort.

[0004] This application provides a cooling garment, which includes a clothing body, a cooling sheet, a fan and a battery. An air inlet channel and an air outlet channel are provided on the clothing body. The air inlet channel and the air outlet channel are independent of each other, and each communicates with the outside and the internal space of the clothing body. The air inlet channel and the air outlet channel are arranged in a cross manner, and the cooling sheet is arranged at the intersection. The cooling sheet has a cooling surface and a heat dissipation surface. The cooling surface faces the air inlet channel, and the heat dissipation surface faces the air outlet channel. The fan and the battery are both arranged on the clothing body. The fan is used to enable outside air to enter the internal space of the clothing body from the air inlet channel, and to enable the air in the internal space of the clothing body to be discharged from the air outlet channel. The fan, the cooling sheet and the battery are electrically connected to be powered by the battery.

[0005] In one embodiment, the air inlet channel has a first air inlet communicating with the outside and a first air outlet communicating with the internal space of the clothing body. The air outlet channel has a second air inlet communicating with the internal space of the clothing body and a second air outlet communicating with the outside. The fan is arranged at the first air inlet and / or the second air outlet.

[0006] In this way, the fan is arranged on the side of the clothing body facing outwards, and the wearing comfort of the user is better.

[0007] In one embodiment, a screen is provided at at least one of the first air inlet, the first air outlet, the second air inlet and the second air outlet.

[0008] In this way, setting the screen can prevent foreign objects such as mosquitoes and bees from entering the internal space of the clothing body.

[0009] In one embodiment, at the intersection of the air inlet channel and the air outlet channel, the air inlet channel is closer to the internal space of the clothing body than the air outlet channel.

[0010] In this way, the air intake channel is closer to the human body than the air outlet channel, and the cooling surface of the cooling sheet faces the human body side, so that the cooling effect is better.

[0011] In one embodiment, a heat sink is provided on the heat dissipation surface of the cooling sheet.

[0012] In this way, setting the heat sink can further accelerate the heat dissipation of the cooling sheet, thereby ensuring the normal operation of the cooling sheet and being beneficial to extending the service life of the cooling sheet.

[0013] In one embodiment, the heat sink includes a heat dissipation main body and a plurality of heat dissipation fins. The heat dissipation main body is attached to the heat dissipation surface of the cooling sheet, and the heat dissipation fins are connected to the edge of the heat dissipation main body and extend beyond the intersection of the air intake channel and the air outlet channel.

[0014] In this way, by contacting the heat dissipation surface of the cooling sheet through the heat dissipation main body, the heat generated by the cooling sheet can be transferred to the heat dissipation fins in time and taken away by the heat sink.

[0015] In one embodiment, the plurality of heat dissipation fins are arranged at intervals and extend along the length direction of the air outlet channel.

[0016] In this way, the air flowing in the air outlet channel can take away the heat on the heat sink in time, so that the heat sink has a better heat dissipation effect.

[0017] In one embodiment, the heat sink is a copper sheet or an aluminum sheet; and / or, the thickness of the heat sink is 0.5 mm to 5 mm.

[0018] In this way, it has a better heat dissipation effect and does not affect the wearing comfort of the cooling clothing.

[0019] In one embodiment, the clothing body is made of a composite fabric. The composite fabric includes a fabric layer and a reflective film layer provided on the surface of the fabric layer. The solar reflectance of the reflective film layer is ≥80%, and the near-infrared reflectance of the reflective film layer is ≥80%.

[0020] In this way, the clothing body has a good anti-solar radiation effect, can effectively reduce the temperature of the internal space of the clothing body, and thus greatly improves the wearing comfort of the human body.

[0021] In one embodiment, the reflective film layer is a PVC film or a PU film;

[0022] and / or, the thickness of the reflective film layer is 50 μm to 5000 μm;

[0023] And / or, the breaking tensile strength of the composite fabric is ≥200N, the trouser-shaped tear strength is ≥8N, and the peeling strength between the reflective film layer and the fabric layer is ≥5N.

[0024] In this way, the performance such as the tensile strength and tear strength of the clothing body can be improved, so that the clothing body has a long service life.

[0025] Compared with the prior art, in the cooling clothing provided by the present application, since the cooling surface of the cooling sheet faces the air inlet passage, the cooling sheet can cool the air entering the internal space of the clothing body, thereby cooling the user. At the same time, since the heat dissipation surface of the cooling sheet faces the air outlet passage, the air outlet passage can also take away the heat generated by the heat dissipation surface in time when discharging the air, avoiding the influence on the cooling effect or even damage caused by the failure of the cooling sheet to dissipate heat in time, thereby ensuring that the cooling sheet can work normally and be used for a long time.

[0038] Please refer to Figure 1 and Figure 2, this application provides a cooling garment, including a garment body 1, a cooling sheet 2, a fan 4 and a battery 5. An air inlet channel 11 and an air outlet channel 12 are provided on the garment body 1. The air inlet channel 11 and the air outlet channel 12 are independent of each other and each communicate with the outside and the internal space of the garment body 1. The air inlet channel 11 and the air outlet channel 12 are arranged in a cross pattern, and the cooling sheet 2 is provided at the intersection. The cooling sheet 2 has a cooling surface 21 and a heat dissipation surface 22. The cooling surface 21 faces the air inlet channel 11, and the heat dissipation surface 22 faces the air outlet channel 12. Both the fan 4 and the battery 5 are provided on the garment body 1. The fan 4 is used to enable outside air to enter the internal space of the garment body 1 from the air inlet channel 11 and to enable the air in the internal space of the garment body 1 to be discharged from the air outlet channel 12. The fan 4, the cooling sheet 2 and the battery 5 are electrically connected to be powered by the battery 5. It can be understood that the "internal space of the garment body 1" refers to the space for a person to wear. In this way, when the fan 4 and the cooling sheet 2 are turned on, outside air enters the internal space of the garment body 1 from the air inlet channel 11, and the air in the internal space of the garment body 1 is discharged to the outside from the air outlet channel 12. Since the cooling surface 21 of the cooling sheet 2 faces the air inlet channel 11, the cooling sheet 2 can cool the air entering the internal space of the garment body 1, thereby cooling the user. At the same time, since the heat dissipation surface 22 of the cooling sheet 2 faces the air outlet channel 12, the air outlet channel 12 can also take away the heat generated by the heat dissipation surface 22 in time when discharging air, preventing the cooling sheet 2 from being unable to dissipate heat in time, which may affect the cooling effect or even cause damage, thus ensuring that the cooling sheet 2 can work properly and be used for a long time.

[0039] The air inlet channel 11 has a first air inlet 111 communicating with the outside and a first air outlet 112 communicating with the internal space of the garment body 1. The air outlet channel 12 has a second air inlet 121 communicating with the internal space of the garment body 1 and a second air outlet 122 communicating with the outside. The fan 4 is provided at the first air inlet 111 and / or the second air outlet 122. In this way, the fan 4 is arranged on the outer side of the garment body 1, and the wearing comfort of the user is better. It can be understood that when the fan 4 is provided at the first air inlet 111, the air inlet surface of the fan 4 faces the outside, and the air outlet surface faces the air inlet channel 11. In this way, the outside air can be blown into the air inlet channel 11 and enter the internal space of the garment body 1 through the air inlet channel 11. When the fan 4 is provided at the second air outlet 122, the air inlet surface of the fan 4 faces the air outlet channel 12, and the air outlet surface faces the outside. In this way, the air in the internal space of the garment body 1 can be sucked out to the outside. Figure 1In the illustrated embodiment, only the first air inlet 111 is provided with the fan 4. When the fan 4 is working, the outside air enters the internal space of the clothing body 1 through the air inlet channel 11, so that the air in the internal space of the clothing body 1 increases and the air pressure increases, so that the air can be discharged from the air outlet channel 12. However, it is not limited to this. In other embodiments, only the second air outlet 122 may be provided with the fan 4. When the fan 4 is working, the air in the internal space of the clothing body 1 is discharged to the outside from the air outlet channel 12, so that the air in the internal space of the clothing body 1 decreases and the air pressure decreases, so that the outside air can enter the internal space of the clothing body 1 from the air inlet channel 11. In addition, the first air inlet 111 and the second air outlet 122 may be provided with the fan 4 at the same time, so that the air flow is more efficient and the cooling effect is better.

[0040] In the present application, a battery 5 is used to power the fan 4 and the heat sink 3. The battery 5 can be a lithium battery. Further, a rechargeable battery 5 can be used, so that it can be charged multiple times for more convenience. The battery 5 can be set to be hung on the waist of the human body, so as to further improve the wearing comfort of the cooling clothing.

[0041] Further, at least one of the first air inlet 111, the first air outlet 112, the second air inlet 121, and the second air outlet 122 is provided with a gauze 13. The gauze 13 can prevent foreign objects such as mosquitoes and bees from entering the internal space of the clothing body 1. Preferably, the first air inlet 111, the first air outlet 112, the second air inlet 121, and the second air outlet 122 are all provided with a gauze 13.

[0042] Furthermore, at the intersection of the air inlet channel 11 and the air outlet channel 12, the air inlet channel 11 is closer to the inner space of the clothing body 1 than the air outlet channel 12. In this way, the air inlet channel 11 is closer to the human body than the air outlet channel 12, and the cooling surface of the cooling plate 2 faces the human body, so that the cooling effect is better.

[0043] In this embodiment, the cooling plate 2 is a semiconductor cooling plate, which has a small volume and good heat dissipation effect.

[0044] For further information, see Figure 3 and Figure 4 , a heat sink 3 is provided on the heat dissipation surface 22 of the refrigeration fin 2. In this way, the heat sink 3 can further accelerate the heat dissipation of the refrigeration fin 2, thereby ensuring the normal operation of the refrigeration fin 2 and being conducive to extending the service life of the refrigeration fin 2.

[0045] In this embodiment, the heat sink 3 includes a heat dissipation main body 31 and a plurality of heat dissipation fins 32. The heat dissipation main body 31 is attached to the heat dissipation surface 22 of the refrigeration sheet 2, and the heat dissipation fins 32 are connected to the edge of the heat dissipation main body 31 and extend beyond the intersection of the air inlet channel 11 and the air outlet channel 12. In this way, by the heat dissipation main body 31 contacting the heat dissipation surface 22 of the refrigeration sheet 2, the heat generated by the refrigeration sheet 2 can be transferred to the heat dissipation fins 32 in time and taken away by the heat sink 3.

[0046] Further, as Figure 4 shown, the plurality of heat dissipation fins 32 are arranged at intervals and extend along the length direction of the air outlet channel 12. In this way, the air flowing in the air outlet channel 12 can take away the heat on the heat sink 3 in time, so that the heat sink 3 has a better heat dissipation effect.

[0047] The heat sink 3 is made of copper sheet or aluminum sheet. In this way, the heat sink 3 has a high heat transfer rate and fast heat dissipation.

[0048] Further, the thickness of the heat sink 3 is 0.5 mm to 5 mm. In this way, it has a better heat dissipation effect and does not affect the wearing comfort of the cooling clothes. Specifically, the thickness of the heat sink 3 can be 0.5 mm, 0.6 mm, 0.7 mm, 0.8 mm, 0.9 mm, 1.0 mm, 1.3 mm, 1.5 mm, 1.8 mm, 2 mm, 2.5 mm, 3 mm, 3.5 mm, 4 mm, 4.5 mm, 5 mm, or any other arbitrary value within the range of 0.5 mm to 5 mm.

[0049] Please refer to Figure 1 , in this embodiment, the air inlet channel 11 and the air outlet channel 12 are in an X shape, and the structure is very simple. Further, the air inlet channel 11 and the air outlet channel 12 are arranged on the back of the clothing body 1, that is, at the position corresponding to the human back, so that a zipper can be arranged on the front side of the clothing body 1, which is convenient for the user to wear.

[0050] Please combine with Figure 5 shown. Further, the clothing body 1 is made of a composite fabric 7. The composite fabric 7 includes a fabric layer 71 and a reflective film layer 72 arranged on the surface of the fabric layer 71. The fabric layer 71 makes the clothing body 1 have better wearing comfort, and the reflective film layer 72 makes the clothing body 1 have better sun protection performance, which can reduce the heat of solar radiation, make the temperature of the internal space of the clothing body 1 decrease, and thus further improve the wearing comfort.

[0051] Further, the solar light reflectance of the reflective film layer 72 ≥ 80%, and the near-infrared reflectance of the reflective film layer 72 ≥ 80%. In this way, the clothing body 1 has a better anti-solar radiation effect, can effectively reduce the temperature of the internal space of the clothing body 1, and thus greatly improves the human wearing comfort.

[0052] Furthermore, the breaking tensile strength of the composite fabric 7 is ≥200 N, the trouser-shaped tear strength is ≥8 N, and the peeling strength between the reflective film layer 72 and the fabric layer 71 is ≥5 N. In this way, the tensile strength, tear strength and other properties of the clothing body 1 can be improved, so that the clothing body 1 has a long service life.

[0053] Furthermore, the material of the fabric layer 71 can be at least one or more of cotton, linen, chemical fiber (such as polyester, polyurethane, aramid, polyimide, etc.), wool, and biomass materials (such as polylactic acid, chitosan, etc.). Classified by the type of fabric, the fabric layer 71 can be fabrics such as polyester pongee, taslon, knitted fabric, mesh fabric, woven fabric, non-woven fabric, plain cloth, milk silk, Lycra fabric, jacquard fabric, super soft fabric, etc., and this application does not limit this.

[0054] The reflective film layer 72 can be a PVC film or a PU film, which has a good reflection effect. The thinner the thickness of the reflective film layer 72, the worse the effect of reflecting sunlight and near-infrared. The thicker the thickness of the reflective film layer 72, the heavier the composite fabric 7, thus affecting the wearing comfort. In this embodiment, the thickness of the reflective film layer 72 is 50 μm to 5000 μm, preferably 100 μm to 2000 μm; more preferably 300 μm to 600 μm. In this way, the clothing body 1 can take into account the performance of being light, thin, breathable, sun-proof and cooling at the same time.

[0055] In one embodiment, the composite fabric 7 can be formed by a hot pressing process. Specifically, first, adhesives such as hot melt adhesive, hot melt film or hot melt powder are melted into a liquid colloid by heating, then the melted glue liquid is evenly coated on the fabric layer 71 by a coater, and finally the fabric layer 71 coated with the glue liquid and the reflective film layer 72 are placed in a hot press for hot pressing treatment, and the composite fabric 7 can be obtained after cooling.

[0056] In summary, the cooling clothing provided by this application can achieve internal cooling, greatly improving the wearing comfort in a high-temperature environment, and can be applied to clothing for summer outdoor activities and high-temperature working environments, such as bee-proof clothing, sanitation clothing, mining work clothes and other fields.

[0057] Taking the bee-proof clothing as an example, for the cooling clothing made of the above-mentioned composite fabric 7, when the fan 4 and the heat sink 3 are not turned on, the temperature of the internal space of the clothing body 1 can be 1°C to 2°C lower than the outside air temperature. After the fan 4 and the heat sink 3 are turned on, the temperature of the internal space of the clothing body 1 can be 5°C to 10°C lower than the outside air temperature, and the cooling effect is very obvious.

[0058] The technical features of the above-described embodiments can be combined arbitrarily. For the sake of brevity of description, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, it should be considered as the scope described in this specification.

[0059] The embodiments described above merely represent several implementation manners of the present application. The description thereof is relatively specific and detailed, but it should not be construed as a limitation on the scope of the patented application. It should be noted that for those of ordinary skill in the art, without departing from the concept of the present application, several modifications and improvements can still be made, and these all fall within the protection scope of the present application. Therefore, the patent protection scope of the present application shall be subject to the appended claims.
