Problems solved by technology

[0004] An inflatable vest jointly developed by Hao Jingya and Xingfengqiang Technology Co., Ltd. The body of the inflatable vest is divided into several regular hexagonal airbags of equal size and connected. There is no other filler in the airbag, and the maximum inflatable thickness is 2.5cm. It is an H-shaped men's vest with equal width and stand-up collar. There is a difference of 33% in the heat retention rate between the uninflated state and the inflated state, but when the inflated thickness is 1cm to 2.5cm, the heat retention rate difference is only 3.76%.
[0005] At present, the clothing products that use the inflatable structure to improve the thermal performance have no filler in the airbag, the static air content and retention capacity in the airbag are low, and the natural convection is relatively serious, which leads to the increase of the clothing before and after the clothing is inflated, and with the increase of the inflated amount. The improvement of thermal resistance is not significant enough, and it is easily affected by external environmental conditions such as wind speed; at the same time, the effective adjustment range of the thermal resistance of the current inflatable structure and clothing is very narrow, which cannot meet the adjustment of the inflation volume to adapt to a wider environment.

Embodiment 1

[0025] The invention discloses an adjustable thermal resistance inflatable device, such as figure 1 and 2 As shown, it specifically includes an air-filled layer and a filling layer; the air-filled layer includes an inner layer close to the human skin and an outer layer far away from the human skin, and the edges of the inner layer and the outer layer are connected to form a sealed cavity, and the sealed cavity A plurality of inflatable parts and shaped parts are set in the room, and the inflated parts and shaped parts form air bags for storing gas, wherein the inflated parts and shaped parts are distributed at regular intervals; the filling layer is located inside the air bag, to stabilize the gas inside the airbag.

[0026] It should be noted that the thermal resistance of clothing or materials depends on the content of still air inside, and still air is currently known as one of the best ways of heat insulation. The improvement of the thermal resistance of traditional infl...

Embodiment 2

[0029] The invention discloses an adjustable thermal resistance inflatable device, such as figure 1 and 2 As shown, it specifically includes an air-filled layer and a filling layer; the air-filled layer includes an inner layer close to the human skin and an outer layer far away from the human skin, and the edges of the inner layer and the outer layer are connected to form a sealed cavity, and the sealed cavity A plurality of inflatable parts and shaped parts are set in the room, and the inflated parts and shaped parts form air bags for storing gas, wherein the inflated parts and shaped parts are distributed at regular intervals; the filling layer is located inside the air bag, to stabilize the gas inside the airbag.

[0030] Wherein, the inner layer of the air-filled layer has a planar structure, which can better fit the human body so as to form a static air layer. The outer layer of the inflatable layer has a three-dimensional structure, so that when the gas in the inflatab...

Embodiment 3

[0032] A gas-filled device with adjustable thermal resistance, such as figure 1 and 2 As shown, it specifically includes an air-filled layer and a filling layer; the air-filled layer includes an inner layer close to the human skin and an outer layer far away from the human skin, and the edges of the inner layer and the outer layer are connected to form a sealed cavity, and the sealed cavity A plurality of inflatable parts and shaped parts are set in the room, and the inflated parts and shaped parts form air bags for storing gas, wherein the inflated parts and shaped parts are distributed at regular intervals; the filling layer is located inside the air bag, to stabilize the gas inside the airbag.

[0033] The materials used in the inner and outer layers are all air-tight materials, such as high-density, coated fabrics, PVC films and other air-tight materials, so that the inflatable part can form a closed space for storing gas.

Abstract

The invention relates to the field of clothing, and provides an inflation device with adjustable thermal resistance. An air bag is filled with wadding to increase the content of internal still air, so that the stability of the still air is improved, excessive natural convection in the air bag caused by external environment change or human body activity is avoided, the adjustable range of the thermal resistance of the inflation structure is greatly improved, so that the improvement effect of the change of the inflation volume on the heat retention property of the clothes is more obvious, and the requirement for effectively adjusting the thermal resistance of the clothes in production and life scenes can be practically met.

Description

technical field [0001] The invention relates to the field of clothing, in particular to an inflatable device with adjustable thermal resistance. Background technique [0002] Su Wenzhen et al. developed a new type of inflatable jacket based on the inflatable vest of NuDown Company in the United States. The inflatable fabric of the body is made of two layers of film-fabric composite materials inside and outside to form closed airbags. The airbags are connected by air channels and are not inflated. The thickness of the airbag is 0.3cm, and the thickness of the filled airbag is 1.85cm. The airbag is diamond-shaped and evenly distributed on the upper body, and the inflation and deflation of the garment is controlled by the rubber air pump and the pressure relief valve connected to the airbag. The sleeves are a combination of water-repellent film-coated fabric and polyester lining. When the clothing is not inflated and inflated, the total thermal resistance of the upper body di...
