Description
Technical Field
[0001] The utility model belongs to the technical field of fully enclosed protective clothing, and in particular relates to a novel fully enclosed thermal insulation protective clothing. Background Art
[0002] The current design trend of fully enclosed protective clothing focuses on achieving top-level isolation performance and a light and fast wearing experience to adapt to diverse and challenging work scenarios. Protective clothing on the market has initially established an isolated protection environment for users by integrating an external air supply system, but it still faces several functional limitations:
[0003] Insufficient thermal insulation and environmental adaptability: Suppose a worker needs to conduct scientific research in the field within the Arctic Circle, and the external ambient temperature is as low as minus 30℃. The worker is wearing a fully enclosed protective suit on the current market. The design of the protective suit focuses on lightness and flexibility, but compromises are made in the use of thermal insulation materials. It mainly relies on the external air supply system to deliver normal temperature (about 25℃) air to maintain the internal environment. However, in such a cold environment, even with a continuous supply of hot air, the thin protective clothing material cannot be well insulated, causing cold air to quickly penetrate the protective clothing material, making it difficult to maintain the internal temperature of the protective clothing at a comfortable level, causing the wearer to quickly feel cold, and causing low-temperature related health problems such as frostbite or hypothermia, seriously affecting work performance and personnel safety. On the contrary, if the same protective clothing is used in a high-temperature environment in a desert area, with an external temperature of up to 50℃, although the protective clothing can continuously input cooled comfortable temperature air, due to the poor thermal insulation performance of the thin protective clothing material, the external high temperature can still significantly affect the temperature environment inside the protective clothing, making the wearer feel stuffy and unbearable, which also affects work efficiency and health.
[0004] Internal air quality management defects: Although external air supply is provided, the carbon dioxide emission efficiency inside the protective clothing is not high. Long-term use can easily cause the wearer to feel stuffy, reducing wearing comfort and the ability to continue working.
[0005] Respiratory humidity and visual impairment: To date, protective clothing has not found an ideal solution for dealing with respiratory humidity. Humidity often condenses into fog on the surface of the transparent hood, greatly hindering the wearer's visual clarity, which poses a direct threat to work safety and reduces operational efficiency. Utility Model Content
[0006] In order to make up for the above-mentioned deficiencies, the purpose of the utility model is to provide a new type of fully enclosed thermal insulation protective clothing, which is designed to solve the problems of insufficient thermal insulation, incomplete removal of carbon dioxide and fogging of the hood in existing protective clothing under extreme climatic conditions, so as to improve the wearer's working efficiency and comfort.
[0007] The utility model is realized through the following technical scheme: a novel fully enclosed thermal insulation protective clothing, including a protective clothing body, characterized in that: the protective clothing body includes a transparent enclosed hood and a enclosed body made of a thermal insulation composite material, the enclosed hood is sealed and connected to the enclosed body; the enclosed body includes a sealed top and trousers to form a sealed integrated structure; an air leakage-proof zipper for human entry and exit is arranged on the enclosed body; an air interface and an exhaust interface for connecting to an external air circulation device are arranged on the enclosed body; the thermal insulation composite material includes an outer anti-breathable layer and an inner thermal insulation layer.
[0008] Furthermore, a fiber layer for enhancing the tensile strength is provided between the anti-air permeability layer and the thermal insulation layer.
[0009] Furthermore, the material of the fiber layer is fiber woven cloth.
[0010] Furthermore, the material of the anti-air permeability layer is thermoplastic polyurethane or polyvinyl chloride.
[0011] Furthermore, the closed hood is made of thermoplastic polyurethane or polyvinyl chloride.
[0012] Furthermore, the material of the thermal insulation layer is fiber cotton.
[0013] Furthermore, the closed garment body also includes sealed connected gloves and shoes to form a sealed integrated structure connected to the top and pants.
[0014] Further, rubber gloves are put on the gloves of the closed body.
[0015] Furthermore, protective shoes are mounted on the closed-body shoes.
[0016] Furthermore, a breathing collection component is arranged inside the protective suit body, and the breathing collection component includes a breathing collection mask fixed to the human face, a hose connected to the breathing collection mask at one end, a filter material fixed inside the hose, and a negative pressure fan arranged at the other end of the hose.
[0017] Beneficial effects and features of the utility model:
[0018] Optimized closure, structural strength and thermal insulation performance: The utility model protective clothing adopts thermal insulation composite material, which consists of an outer anti-permeable layer (using thermoplastic polyurethane or polyvinyl chloride to effectively isolate the external environment), a middle reinforced fiber layer (using fiber fabric to enhance the physical strength and wear resistance of the clothing), and an inner high-efficiency thermal insulation layer (using fiber cotton as raw material to ensure excellent thermal insulation effect). This multi-layer structural design not only achieves an excellent sealing effect to prevent the wearer from being affected by extreme external climate, but also significantly enhances the physical strength of the clothing, enabling it to withstand high-intensity operations without being easily damaged. At the same time, it ensures that a suitable and stable temperature environment is maintained inside under various climatic conditions, improving the wearer's comfort and work efficiency.
[0019] Enhanced carbon dioxide removal and anti-fogging design: Through the built-in breathing collection component, especially the circulation filtration system driven by the negative pressure fan, this protective suit can efficiently absorb the carbon dioxide and moisture produced by breathing into the hose, and use the soda lime built into the hose for chemical reaction to completely remove these harmful factors, thus solving the problem of carbon dioxide accumulation inside the existing protective suit and fogging of the hood. This design not only improves the quality of breathing air, but also ensures a clear field of vision for the wearer, ensuring safety and efficiency in tense or delicate operations.

[0026] The following combination Figure 1-4 , the contents of the utility model are described in detail through specific embodiments. Example
[0027] The protective clothing of this embodiment is composed of a protective clothing body, which includes a transparent closed hood 1, which is made of thermoplastic polyurethane material or polyvinyl chloride to ensure a good field of vision and has air-proof properties; and a closed body 2 made of a thermal insulation composite material 7, which includes an air-proof layer 701, a thermal insulation layer 702 and a fiber layer 703, wherein the fiber layer is made of fiber woven fabric to enhance structural strength. The closed hood and the closed body are tightly connected through a high-sealing seam technology to ensure complete isolation of the internal and external environments.
[0028] Application of thermal insulation composite materials: The thermal insulation layer is made of fiber cotton, and the outer anti-permeable layer is made of thermoplastic polyurethane or polyvinyl chloride. This thermal insulation composite material design not only effectively isolates the outside cold and heat, but also maintains the appropriate temperature of the wearer's body surface. A fiber layer is added between the anti-permeable layer and the thermal insulation layer. The fiber layer is first woven with fiber cloth to improve the overall durability and tensile strength of the clothing.
[0029] Convenience and comfort of wearing: The closed garment body is designed as an integrated structure, including a top, gloves, pants and shoes. All parts are sealed to ensure good airtightness. The gloves and shoes are designed to fit the human body. The outer layer of the gloves is covered with rubber gloves 4, and the shoes are equipped with protective shoes 5, which increases the protective performance and durability during operation. The front side is equipped with an airtight zipper 3, which is convenient for the wearer to quickly enter and exit, while ensuring sealing and reducing heat loss.
[0030] Air quality control: The back side of the protective suit is equipped with an air interface 6 and an exhaust interface 8, which are connected to an external air circulation device through a connecting hose. The external air circulation device can continuously deliver 25°C air to the inside of the protective suit, and at the same time, it can retract the air inside the protective suit to form a closed loop, so as to achieve temperature regulation and circulation renewal of the air inside the protective suit. It is particularly worth mentioning that the internally installed respiratory collection component 9 includes a respiratory collection mask 901, a hose 902, a filter material 903 and a negative pressure fan 904. The component works through a negative pressure fan, and the exhaled gas in the mask is introduced through a hose. The soda lime inside the hose can effectively absorb carbon dioxide and moisture, reduce the internal carbon dioxide content and prevent the hood from fogging, ensuring the wearer's good field of vision and breathing quality. The negative pressure fan can work through an external battery or through a wire connected to an external power source.
[0031] Convenience of maintenance and upgrade: The hose is designed as a detachable plug-in structure, which is convenient for regular replacement of soda lime particles. It also facilitates the cleaning and maintenance of the entire respiratory collection assembly, ensuring stable performance under long-term use.
[0032] To sum up, the new fully enclosed thermal insulation protective clothing of this embodiment effectively solves many key problems existing in existing protective clothing through carefully designed thermal insulation composite materials, efficient breathing and circulation systems, and humanized detail processing, and achieves the goal of allowing the wearer to maintain efficient operation and high comfort in various harsh climates, reflecting the innovation and practicality of the utility model.
