Firefighter uniform with intelligent heat and humidity transmission adjusting function

Abstract

The invention relates to a firefighter uniform with the intelligent heat and humidity transmission adjusting function. The firefighter uniform comprises a top and / or trousers. An outer layer, a waterproof breathable layer and a comfortable layer are sequentially arranged in the top and / or the trousers from outside to inside. Multiple temperature-sensing drive elements are arranged between the outer layer and the waterproof breathable layer and between the waterproof breathable layer and the comfortable layer. The temperature-sensing drive elements are shape memory springs. According to the firefighter uniform with the intelligent heat and humidity transmission adjusting function, shape memory spring arrays are arranged, and the thickness of the firefighter uniform can be adjusted automatically, so that the heat and humidity transmission adjusting performance is adjusted, wear comfort is achieved, and motion of limbs is not affected.

Description

technical field [0001] The invention relates to a firefighting suit, in particular to a firefighting suit for intelligently adjusting heat and moisture transfer. Background technique [0002] Firefighters or emergency rescue personnel are often exposed to thermal hazards such as flames, radiation, and splashes from high-temperature objects. They need to wear specific firefighting clothing to protect their health and personal safety. In order to improve the protective performance of firefighting clothing, it is generally achieved by developing new flame-retardant fiber materials, increasing the thickness and number of layers of the fabric, or increasing the size of the clothing. The development of flame-retardant fibers has been relatively mature, and its research and development is very difficult. Traditional firefighting clothing mainly increases the thermal resistance of clothing through the combination of multi-layer clothing to improve thermal protection performance. Ge...

Problems solved by technology

[0004] However, due to the thick multi-layer structure of traditional firefighting clothing, the effect of increasing ventilation and heat dissipation by changing the structure and style design is very limited, and cannot effectively alleviate the heat stress generated during emergency rescue.

The working environment of firefighters determines that fan cooling cannot be used in firefighting clothing. Other cooling devices need to be covered with pipes all over the body, carry cooling equipment, power supply, cooling bags, etc., which not only affect the heat and moisture transfer of the clothing body, but also restrict body movements. , poor environmental adaptability, limited duration of cooling effect, etc., and increase the weight of the human body and metabolic heat generation; gas cooling suits are covered with air supply hoses, which need to be connected to an air compressor to cool, and the range of human activities is easily affected by the length of the trachea Similar to gas cooling suits, the length of the liquid cooling suit using a mobile refrigeration device limits the wearer's range of activities, and the liquid cooling suit with a portable liquid cooling device increases the weight of the human body, and the volume of the refrigeration box is limited. The cooling time is short; the effective cooling time of the phase change cooling bag is short, the cooling effect is uneven, the cooling bag needs to be replaced on time, the weight is heavy, the human body load is increased, the metabolic heat production is increased, the air permeability is poor, and the clothing body heat and moisture transfer

The maximum cooling effect produced by the above cooling devices generally occurs at the early stage of wearing, which may cause cold stimulation and affect the wearing comfort; in addition, in extreme or dangerous environments, the cooling device may be damaged, not only cannot continue to perform cooling effect, and may even produce substances such as molten droplets that are harmful to the human body

Therefore, none of the above means can achieve the ideal use effect, and there is an urgent need to design intelligent fire protection clothing with excellent heat dissipation effect, comfortable wearing, long use time, no stimulation to the human body, and no influence on limb movement.
