Description

Protective clothing with internal environment heat and humidity load regulation and control function Technical Field The invention relates to the technical field of individual protection, in particular to a protective garment with an internal environment heat and humidity load regulating function. Background The protective clothing is used as necessary individual protective equipment, protects the health and safety of wearing personnel by isolating the internal and external environments of the clothing, mainly comprises firefighter protective clothing, biochemical protective clothing and the like, and meanwhile, the high-humidity internal environment caused by isolation becomes an important factor endangering personnel. Typically, such as airtight protective clothing, has the effect of blocking external environmental hazard factors (poison, heat, water, dust, etc.), but also blocks the channel of moisture release from the environment to the wearer. In the operation process, the humidity inside the protective clothing is easy to quickly rise due to physiological perspiration, so that the problems of rapidly reducing the perspiration efficiency of a human body, further inducing the rapid rise of the temperature of the human body, causing heatstroke and even heat failure to endanger life and the problems of blocking the sight of the personnel, reducing the visual field, seriously affecting the operation efficiency, even causing misoperation and endangering life are caused. At present, two solutions are mainly provided, namely, the sweat discharging speed is indirectly reduced through human body temperature control equipment, for example, CN120549295A proposes that an electric fan is used for driving air to accelerate sweat evaporation. CN113662291a proposes that semiconductor cooling is combined with air circulation for humidity control, CN208891740U and CN219088466U propose that a cold storage agent is used for cooling so as to realize humidity control, as in CN116538599a, a liquid cooling humidity control method based on a hollow fiber membrane, as in CN216821879U and CN116135063a, a distributed phase change moisture absorption technology based on central control; secondly, the window material of the protective clothing is optimized to slow down the condensation of water vapor, and moisture absorption is carried out through the microstructure of the clothing material or fabric as proposed by CN120844374A, CN120972494A, CN120758993A and the like. The technology adopts the moisture absorption material or the cold accumulation material, which not only increases the mass and possibly needs to be replaced or supplemented due to aging, but also adopts the mechanical, sensing and electric control devices, the mass and the volume of which are difficult to limit, which not only increases the mass and reduces the flexibility, but also obviously reduces the reliability, or through the improvement of the clothing fabric, sweat is temporarily stored in the outer layer of the fabric but also needs to be replaced regularly due to the difficulty in lasting.
