Description

Technical Field

[0001] The present invention relates to the field of clothing cooling technology, and particularly to a cooling vest having an underarm air blowing structure.

Background Art

[0002] In order to meet the needs of outdoor work in high temperature and hot environments in summer, a variety of cooling cooler clothes have been introduced into the market. The basic principle is to cool the human body by semiconductor cooling elements and fans provided in the clothes.

[0003] Although this technical solution can form air flow and refrigerants (mainly cooling the back) inside the clothes, due to the overall structure of the clothes and the special structure of the sleeves, it is difficult to obtain a good cooling effect at the underarm position.

[0004] However, restricted by the overall structure of the clothes and the special shape of the sleeves, it is often difficult to effectively cool the underarm area. The underarm is an important part of the human body where sweating is easy. In this area, sweat glands are densely distributed, and it is located in the fold of the skin, so the air permeability is poor, the temperature and humidity are high, and it is easy to form a sealed microenvironment, which is disadvantageous for the evaporation of sweat. Therefore, in the design of functional clothes (such as heat dissipation vests, sportswear, etc.), the air permeability, sweat discharge efficiency and wearing comfort of the underarm area are particularly important. Currently, many common clothes mainly aimed at underarm cooling mainly provide ventilation holes at the underarm position to promote the volatilization of sweat, thereby realizing passive cooling.

[0005] In conventional technology, the document with Chinese patent publication number CN215189512U proposes a cooling suit that uses a cooling fan and ice pack in combination to cool the body, and features detachable sleeves that can be removed to cool the entire sleeve area. The documents with Chinese patent publication numbers CN102423147A and CN209660492U disclose cooling suits with a double airflow structure, respectively. While CN209660492U directs airflow to the underarms through the airflow channels to achieve localized heat dissipation, the addition of a guide assembly to the double structure makes the overall structure complex and heavy, significantly impacting comfort and flexibility when worn.

[0006] As described above, ensuring structural simplicity, lightness, and comfort while effectively supplying cooling airflow to high-temperature, high-humidity areas such as the underarms is a technical challenge that urgently needs to be addressed in current functional thermal clothing. [Overview of the project] [Problems that the invention aims to solve]

[0007] The present invention aims to provide a cooling vest having an underarm ventilation structure in order to solve one of the above-mentioned defects. [Means for solving the problem]

Modes for Carrying Out the Invention

[0020] Hereinafter, the present invention will be described in more detail in combination with the drawings and specific embodiments.

[0021] To facilitate understanding, the present invention will now be described in more detail by combining specific embodiments, but this is not intended to limit the present invention.

[0022] Example 1 As shown in Figure 1-5, the present invention discloses a cooling vest having an underarm ventilation structure, comprising a vest body 1, a heat dissipation fan 2, and a controller. The heat dissipation fan 2 is used to send air into the inside of the vest body 1. A pull tape 102 is provided on the inside of the vest body 1, and the pull tape 102 is provided on the lower inside of the armhole 101. Both ends of the pull tape 102 are connected to the inner surface of the vest body 1 and are used to pull the two connection points together. After being pulled together, the armhole 101 deforms, the lower part of the armhole 101 protrudes outward, and an upward-opening air outlet 103 is formed between the pull tape 102 and the protruding part. The heat dissipation fan 2 is provided on the lower part of the vest body 1, and a portion of the airflow generated by the heat dissipation fan 2 can be blown directly under the armpit through the air outlet 103. Because the rest of the vest is in close contact with the body, much of the airflow generated by the heat dissipation fan 2 is blown under the armpit through the air outlet 103, achieving a good underarm cooling effect. For outdoor workers in particular, when their arms are slightly open, wind is more likely to blow towards their armpits.

[0023] In this embodiment, both ends of the pull tape 102 are fixed and connected to the vest body 1 by sewing.

[0024] To prevent damage to the connection point between the tension tape 102 and the vest due to pulling during the vest's wearing process, the tension tape 102 is an elastic tension tape 102, specifically an elastic rubber band, and in practice, it may be an elastic wire or rubber thread.

[0025] A mobile battery is integrated into the controller, and the cooling fan 2 is electrically connected to the controller. Specifically, the controller supplies power to the cooling fan 2 via a TYPE-C charging cable (or DC cable), and the controller is used to control the opening and closing of the cooling fan 2 and adjust the fan speed. A pocket 104 is provided on the outside of the vest for storing the controller.

[0026] To allow heat to dissipate by opening the front of the vest, an adjustable insert buckle 105 is provided on the front of the vest. In this embodiment, there are three sets of insert buckles 105: upper, middle, and lower. Specifically, the insert buckles 105 have a Japanese-style buckle structure. Both the insert buckles 105 and the Japanese-style buckle are conventional, mature technologies. For example, the shoulder straps of a backpack are adjusted in length using a Japanese-style buckle structure, and the two shoulder straps are secured using insert buckles.

[0027] In practical use, instead of using the pull tape 102, the two connection points between the pull tape 102 and the inner surface of the vest body 1 are directly sewn together.

[0028] Example 2 As shown in Figure 6, the difference between this embodiment and the above embodiment is that the inside edge of the air outlet 103 and the pull tape 102 are closed by hook and loop fastener (registered trademark). Specifically, a male part (not shown) and a female part 1022 are provided on the inside edge of the pull tape 102 and the air outlet 103, respectively, and the pull tape 102 and the inside edge of the air outlet 103 are closed by the combination of the male part 1021 and the female part 1022.

[0029] Example 3 As shown in Figure 7, the difference between this embodiment and Embodiment 2 is that the free end of the pull tape 102 is detachably connected to the vest body, while the other end is fixedly connected to the vest body.

[0030] In this embodiment, the free end of the pull tape 102 is detachably connected to the vest body by Velcro®. Specifically, a male part 1021 is provided on the free end of the pull tape 102, and a female part 1022 is provided on the inside edge of the air vent 103. By adjusting the position where the free end of the pull tape 102 and the edge of the air vent 103 are connected, the size of the air vent 103 can be adjusted. For example, if it is necessary to enlarge the air vent 103, the Velcro® can be tightened, and if it is not necessary to enlarge the air vent 103 excessively, the Velcro® can be released. At the same time, by adjusting the size of the air vent 103 using Velcro®, it is possible to adapt it to people with different body types.

[0031] Example 4 As shown in Figure 8, the difference between this embodiment and Embodiment 2 is that in this embodiment, a hook 1023 is provided at the free end of the pull tape 102, a positioning hole 106 is provided on the inside edge of the air outlet 103, and by hooking the positioning holes 106 at different positions with the hook 1023, the size of the air outlet 103 and the closing of the air outlet 103 can be controlled.

[0032] Example 5 As shown in Figure 9, the difference between this embodiment and the above embodiment is that the pull tape 102 includes a fixed part 1024 and a movable part 1025.

[0033] In this embodiment, the fixing part 1024 is a tension ring 1026, which is fixed and connected to the inner surface of the vest body, and the movable part 1025 is provided with Velcro®, the male part 1021 and female part 1022 of which are located on one side of the movable part 1025 facing the human body, and the male part 1021 is provided at the free end of the movable part 1025. When in use, the male part 1021 at the free end of the movable part 1025 passes through the tension ring 1026 and is locked into the female part 1022.

[0034] Example 6 As shown in Figure 10, the difference between this embodiment and the above embodiment is that in this embodiment, both ends of the pull tape 102 are detachably connected to the vest body by Velcro®.

[0035] Specifically, male parts 1021 are provided at both ends of the pull tape 102, and female parts 1022 are provided on the inside of the vest body. The female parts 1022 are strip-shaped, and the size of the air vent 103 can be adjusted by changing the distance between the male parts 1021. If the air vent 103 is not used, the pull tape 102 may be removed.

[0036] In practical use, buttons or snap buttons can be used at both ends of the pull tape 102, and the size of the air outlet 103 can be adjusted by multiple locking positions.

[0037] In addition to the embodiments described above, the adjustment objective can also be achieved by technical solutions using ordinary clothing accessories such as Japanese-style buckles, buttons, or snap buttons, thereby achieving the technical effect of forming the air vent 103.

[0038] The above description further elaborates on the present invention by combining specific preferred embodiments, and it should not be considered that the specific implementation of the present invention is limited to this description. A person skilled in the art may make some further simple deductions or substitutions, as long as they do not deviate from the concept of the present invention, and all of these should be considered to fall within the scope of protection of the present invention.
