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 protective clothing. Background Art

[0002] In the current field of fully enclosed protective clothing technology, products on the market can create a basic isolated living environment for the wearer by integrating an external air circulation system. However, these existing protective clothing designs expose two core problems that limit their effectiveness and comfort in practical applications:

[0003] First, although most external air circulation systems are equipped with a carbon dioxide removal mechanism, in actual working environments, the concentration of carbon dioxide accumulated inside is still difficult to maintain at a low level, and long-term wearing can easily cause discomfort to the wearer. The root cause of this problem lies in the efficiency bottleneck of existing carbon dioxide removal technology, which fails to achieve rapid and effective gas exchange, thus affecting the wearer's physiological health and work durability.

[0004] Secondly, because the moisture released during breathing contacts the inner surface of the protective suit hood, especially in high humidity environments, the hood is prone to fogging, which seriously hinders the wearer's visual clarity and reduces the accuracy and safety of work. This problem is attributed to the imperfect moisture removal design of the existing respiratory system, which fails to effectively remove moisture or prevent it from condensing within the field of vision.

[0005] Therefore, there is an urgent need for a more advanced fully enclosed protective clothing design, which can not only significantly improve the removal efficiency of carbon dioxide and ensure the physiological comfort of the wearer during long-term work, but also solve the fogging problem of the hood to ensure that the wearer has a clear and unobstructed field of vision, thereby improving the overall performance and wearing experience of the protective clothing. This requires that the new design must innovatively integrate efficient gas purification and intelligent humidity management technologies on the basis of maintaining the original protective function to meet higher standards of application requirements. 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 protective clothing, which solves the problems of insufficient removal of carbon dioxide inside the existing protective clothing and fogging of the hood, which affects the wearer's field of vision.

[0007] The utility model is realized through the following technical scheme: a novel fully enclosed protective clothing, comprising a protective clothing body, characterized in that: the protective clothing body comprises a transparent hood and a positive pressure enclosed body that are sealed and connected; the positive pressure enclosed body comprises a top and pants with a sealed integrated structure; a breathing collection component is arranged inside the protective clothing body, and the breathing collection component comprises a breathing collection mask fixed to the human face, a hose connected to the breathing collection mask at one end, a filter material fixedly arranged inside the hose, and a negative pressure fan arranged at the other end of the hose; an anti-leakage zipper for human entry and exit is arranged on the positive pressure enclosed body; an air intake interface and an exhaust interface for connecting to an external air circulation device are arranged on the positive pressure enclosed body.

[0008] Furthermore, the positive pressure sealing garment body also includes gloves and shoes which are an integral sealing structure.

[0009] Furthermore, the positive pressure closed garment body is provided with an external battery for powering the negative pressure blower.

[0010] Furthermore, the hose is a detachable plug-in structure.

[0011] Furthermore, a wire connected to an external power supply device is provided on the negative pressure fan, and the wire is connected to the external power supply device through an air inlet interface or an air exhaust interface.

[0012] Furthermore, the filter material is granular soda lime.

[0013] Furthermore, the air leakage-proof zipper is arranged on the front side of the positive pressure-sealed garment body.

[0014] Furthermore, the air inlet port and the air outlet port are arranged on the rear side of the positive pressure sealing garment.

[0015] Beneficial effects and features of the utility model:

[0016] Significantly improve the efficiency of carbon dioxide removal: Through the integrated respiratory collection components inside the protective clothing, especially the innovative application of the negative pressure fan and the soda lime filtration system, the utility model can effectively capture and neutralize a large amount of carbon dioxide in the exhaled gas. Compared with traditional protective clothing, it greatly improves the efficiency of carbon dioxide removal, reduces the discomfort of the wearer caused by carbon dioxide accumulation, and ensures the safety and comfort of long-term work.

[0017] Effectively prevent the hood from fogging: The breathing collection component with a circulating filtration design, combined with the absorption of moisture in the exhaled gas by soda lime, effectively solves the problem of hood fogging, ensures that the wearer has a clear and unobstructed field of vision during the mission, and improves work efficiency and safety.

[0018] Enhanced practicality and portability: The detachable plug-in structure design of the hose not only makes it convenient for users to regularly replace the filter material and maintain the purification efficiency of the protective clothing, but also makes the entire equipment more flexible and lightweight, easy to carry and store.

[0019] Improve the flexibility of energy utilization: The connection design between the negative pressure fan and the external power supply device, as well as the external configuration of the battery, provide a reliable energy supply method for the protective clothing. Whether through the built-in battery or the external power supply, it can ensure that the protective clothing can continue to operate in various environments, enhancing the convenience and adaptability of use.

[0020] Integrated design enhances protective performance: The integrated structure of the positive pressure closed body, including the top, gloves, pants and shoes, not only improves the overall sealing of the wearer, but also simplifies the donning procedure, ensuring the wearer's comprehensive protection in high-risk environments. At the same time, the integrated design also optimizes the appearance and enhances the professional image. BRIEF DESCRIPTION OF THE DRAWINGS

[0026] The following combination Figure 1-3 , the contents of the utility model are described in detail through specific embodiments. Example

[0027] The structure and composition of the protective suit: The fully enclosed protective suit of this embodiment is composed of a transparent hood 1 made of highly transparent and wear-resistant polycarbonate material and an integrated positive pressure enclosed garment body 2 made of high-strength composite materials. The positive pressure enclosed garment body with a sealed integrated structure integrates the top, gloves 5, pants and shoes 6, ensuring strict protection of the wearer's whole body. The transparent hood and the garment body are seamlessly connected through sealing technology to ensure complete isolation of the internal and external environments.

[0028] Respiratory collection component design: Inside the protective suit, there is a set of innovative respiratory collection components 3, the core of which is a respiratory collection mask 301. The wearer's face is connected to the negative pressure fan 304 through a hose 302. The hose is filled with high-efficiency filter material, soda lime 303 particles, which can quickly absorb carbon dioxide and moisture in the exhaled gas. The hose is designed as a detachable plug-in structure to facilitate maintenance and replacement of the filter medium.

[0029] Power and airflow management: The negative pressure fan is powered by a built-in battery or an external power supply device, and is connected to the air inlet port 7 or the exhaust port 8 on the rear side of the protective suit through a wire. After the negative pressure fan is started, the air in the mask part and the edge of the mask is sucked into the hose, and at the same time, the gas exhaled by the wearer is prompted to react with soda lime through the hose, and the purified gas returns to the inside of the protective suit, forming a closed loop, avoiding the wearer's exhaled gas directly entering the air inside the protective suit, resulting in an increase in carbon dioxide concentration, and the hood fogging caused by increased air humidity.

[0030] Inlet and outlet and air source interface: The front side of the positive pressure closed garment body is equipped with an air leakage-proof zipper 4 to ensure convenient entry and exit. The back side is provided with an air intake interface and an exhaust interface, which are connected to the external air circulation system through a hose. The external air circulation system can continuously deliver 25°C fresh air to the inside of the protective suit through the air intake interface, and at the same time, collect the air inside the protective suit through the exhaust interface to the carbon dioxide removal device of the external air circulation system, forming a closed loop.
