Description

Technical Field

[0001] This utility model relates to the field of fully enclosed chemical protective suits, and in particular to a fully enclosed chemical protective suit. Background Technology

[0002] Existing fully enclosed chemical protective suits are mostly one-piece designs with a small zippered opening on the back for putting on and taking off, along with other matching sealing structures. Putting on and taking off these suits requires the assistance of multiple people and takes a long time. During on-site work, due to high temperatures, it is necessary to leave the site and go to a safe area to remove the protective suit to cool down. However, traditional protective suits are time-consuming to put on and take off and require cleaning to avoid contamination inside the suit.

[0003] This proposal is put forward in order to improve and optimize the above-mentioned problems or shortcomings. Utility Model Content

[0004] A fully enclosed chemical protective suit includes a one-piece fully enclosed heavy chemical protective suit, wherein the one-piece fully enclosed heavy chemical protective suit has a sealed zipper on the back for putting on and taking off;

[0005] The one-piece, fully enclosed heavy chemical protective suit has a circular opening at the face position, and a waterproof alloy face frame seat is heat-pressed and fixed at the circular opening. The waterproof alloy face frame seat has a passive negative pressure chamber, which is used to adsorb and fix the matching mask structure under negative pressure.

[0006] A visual composite face mask includes an annular alloy frame for press-fitting and fixing within a waterproof alloy frame seat, and a visual protective glass that is sealed and fixed within the alloy frame.

[0007] Preferably, the outer side of the waterproof alloy faceplate is provided with a circular groove, and an annular airtight cavity is formed by an integrated partition. The annular airtight cavity is drawn to a negative pressure state by an external vacuum pump connected to the alloy valve core that is matched on the waterproof alloy faceplate, and the integrated partition is provided with annular through airtight suction holes.

[0008] Preferably, the visual composite face mask includes an alloy composite pressure frame and tempered glass embedded and fixed in the alloy composite pressure frame. The alloy composite pressure frame and the tempered glass are in a sealed connection form, and a rubber sealing ring is fixedly provided on one end face of the alloy composite pressure frame. The rubber sealing ring is embedded in the groove on the outer side of the waterproof alloy face mask seat and is sealed and fitted to the inner wall of the groove. The negative pressure suction of the annular airtight cavity is used to seal and fix the alloy composite pressure frame.

[0009] Preferably, the tempered glass is a double-layered, angled glass.

[0010] Preferably, the alloy valve core is provided with a protective nut with a threaded connection, which protects the alloy valve core when it is not being evacuated or vented.

[0011] Preferably, when the visual composite mask and the waterproof alloy faceplate are attracted together, the end face of the alloy composite pressure ring and the end face of the waterproof alloy faceplate are in direct contact.

[0012] The advantages and positive effects of this utility model are:

[0013] Compared to traditional one-piece, fully enclosed chemical protective suits, this application adopts a modular disassembly design for the face area of ​​the one-piece chemical protective suit. Through negative pressure adsorption and airtight connection, the visual composite mask can be quickly sealed and fixed in the face position to form protection. It can also be quickly disassembled when the protective suit needs to be removed. In many situations, personnel working in high temperatures need to cool down quickly. After cleaning the head protective suit, the visual composite mask can be quickly removed, and then cooling can be achieved through the facial window. Compared with the existing technology, which can only remove the entire protective suit, this is more scientific and convenient. When removing the visual composite mask, only the area around the face needs to be cleaned, which is more convenient. Attached Figure Description
