Description

Technical Field

[0002] Protective devices used in chemical production safety include respiratory protection devices, such as dust masks, gas masks, gas filter protective gear and oxygen respirators, which are mainly used to prevent inhalation of toxic and harmful gases, dust, etc.

[0003] Existing head-mounted respirators are equipment that provide respiratory protection for users and are usually used for people who need to work in environments with harmful gases, vapors, smoke, or low oxygen content. This type of respirator usually has a head-mounted design for easy wearing and fixing, allowing the user to keep the airway open while moving or working. The main components of a head-mounted respirator include a gas cylinder, a pressure reducer, a breathing valve, a mask, and a headband. The gas cylinder stores compressed air, the pressure reducer reduces the high-pressure air to a low pressure suitable for breathing, the breathing valve controls the inflow and outflow of air, the mask provides a connection to the respirator and ensures the quality of the breathable air, and the headband is used to fix the mask to ensure that it fits tightly to the user's face.

[0004] Existing chemical production safety respirators purify the passing air through the adsorbents set inside the respirators during work. However, the adsorption efficiency of the adsorbents inside the respirators will be greatly reduced after being used for a period of time, which will lead to a decrease in the purification quality of the respirators. For this reason, we propose a protective device for chemical production safety. Utility Model Content
