[0023] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0024] like Figure 1-Figure 7 As shown, a cooling vest comprises a front skirt piece 1 and a back skirt piece 2. Two pockets 6 are symmetrically fixed on the front surface of the front skirt piece 1 for placing items. Two shoulder straps 3 are fixed at both ends of the upper end of the back skirt piece 2. Cotton pads for improving comfort are fixed on the inner walls of the shoulder straps 3. The ends of the shoulder straps 3 are fixed to the upper end of the front skirt piece 1 through Velcro 4, which is convenient for quick opening and quick wearing and taking off of the vest. The front skirt piece 1 and the back skirt piece 2 are connected together at both sides by two sets of elastic connecting belts 7. The inner walls of the front skirt piece 1 and the back skirt piece 2 are respectively provided with a plurality of elastic connecting belts 7. A cooling heat conductor 5 is fixed, and the cooling heat conductor 5 includes a heat conductive fabric layer 52, a heat conductive pad 51 is wrapped in the heat conductive fabric layer 52, and at least one groove 53 is formed on the side of the heat conductive pad 51 facing the heat conductive fabric layer 52, and a high-efficiency hard gel 54 is embedded in the groove 53. The heat conductive fabric layer 52 adopts a cool unidirectional heat conductive fabric to facilitate the unidirectional flow of cold air and contact with the human body to cool the human body, while avoiding the contact of the human body's heat with the high-efficiency hard gel 54 to accelerate the consumption of the cold source and shorten the cooling time.

[0025] In this embodiment, the back skirt piece 2 is composed of a hygroscopic fabric layer 21 and a flame retardant fabric layer 22 sewn together. The flame retardant fabric layer 22 is sewn on the outside. The hygroscopic fabric layer 21 can absorb human sweat, and the flame retardant fabric layer 22 can enable the vest to be used in a high temperature environment. The front skirt piece 1 and the back skirt piece 2 have the same structure.

[0026] In this embodiment, the thermal conductive pad 51 is made of a flexible material, preferably sponge, and is formed with a plurality of air holes 511 running through the front and back faces for easy ventilation. The cold air from the high-efficiency hard gel 54 can pass through the thermal conductive pad 51 and contact the hygroscopic fabric layer 21 to reduce the temperature of the hygroscopic fabric layer 21.

[0027] In this embodiment, a plurality of parallel first air permeable grooves 512 are formed on one side of the thermal conductive pad 51, and a plurality of parallel second air permeable grooves 513 are formed on the other side of the thermal conductive pad 51. The first air permeable grooves 512 are perpendicular to the second air permeable grooves 513, and the air holes 511 are connected to the first air permeable grooves 512 and the second air permeable grooves 513. The cold air of the plurality of high-efficiency hard gels 54 can exchange and influence each other through the first air permeable grooves 512 and the second air permeable grooves 513, thereby avoiding uneven cooling effects caused by different consumption rates of the plurality of high-efficiency hard gels 54 when used.

[0028] In this embodiment, an adjustment buckle 8 is fixed on the elastic connecting belt 7. The adjustment buckle 8 is a spring buckle, which is convenient for adjusting the length of the elastic connecting belt 7, thereby improving the ease and comfort of wearing.

[0029] In this embodiment, a plurality of parallel reflective strips 11 are fixed on the outer surfaces of the front skirt piece 1 and the back skirt piece 2 to improve the safety of the wearer in a dim environment.

[0030] In the present embodiment, a plurality of third ventilation grooves 9 are formed on the upper end of the front skirt piece 1, and a shielding piece 10 is fixed at the position of the third ventilation grooves 9 on the front surface of the front skirt piece 1, the upper end of the shielding piece 10 is fixed to the front skirt piece 1, and a counterweight is fixed inside the lower end of the shielding piece 10. A reflective strip 11 is also provided on the outer surface of the shielding piece 10. When a person bends over, the shielding piece 10 maintains a vertical state under the action of its own weight. At this time, the third ventilation grooves 9 are in an open state, which is convenient for ventilation and heat dissipation in front of the person's chest. When the person stands up after bending over, the shielding piece 10 rotates toward the front skirt piece 1 to achieve the effect of fanning the person, thereby performing ventilation and heat dissipation and improving the use effect.

[0031] The working principle of the utility model is as follows: before use, the vest is placed in an ice storage or refrigerator for a period of time to cool down. When wearing it, it is put on the body from top to bottom, and then the shoulder strap 3 is fixed with the Velcro 4, and the position of the adjustment buckle 8 is adjusted so that the front skirt piece 1 and the back skirt piece 2 can be closely attached to the body. The sweat produced by the human body is absorbed by the moisture-absorbing fabric layer 21, and at the same time, the cold air in the high-efficiency hard gel 54 is emitted through the heat-conducting fabric layer 52 to cool the human body, thereby improving the comfort.

[0032] Components not described in detail herein are prior art.

[0033] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
