Composite type electrostatic dustproof face mask

Abstract

The invention provides a composite type electrostatic dustproof face mask. According to the technical scheme adopted by the invention, the dustproof face mask is mainly composed of a direct-current power supply (1) and a face mask body (2), wherein the power supply (1) is connected with the face mask body (2) through an electric wire. A dustproof box (4) is fixedly arranged at the outer side of the lower base of the face mask body (2); a sealing mask (5) is fixedly arranged inside the lower base of the face mask body (2). A face protecting mirror (6) is fixedly arranged on the middle part of the face mask body (2); a small fan (7) is fixedly arranged on the upper part of the face mask body (2); a gas exhaust valve plate (3) is fixedly arranged on the lower side of the sealing mask (5); the two ends of a mask tying belt (8) are fixedly arranged at the two sides of the face mask body (2) separately. Metal wire screens (9) and a filter film (10) are mounted inside a shell (11); a filter membrane (10) is positioned between the two metal wire screens (9); and a gas inlet valve plate (12) is fixedly arranged at the inner side of the shell (11). The composite type electrostatic dustproof face mask has the characteristics of high dust removal efficiency and good man-machine matching performance.

Description

technical field [0001] The invention relates to the field of protective appliances, and specifically designs a composite electrostatic dustproof mask. Background technique [0002] In the 1960s, welding workers in the United States, Italy and other countries and their health departments conducted research on the toxic mechanism of welding fumes. my country has done research on the toxicity and composition of welding fumes since the 1970s. In the 1980s, the Ministry of Health of my country, the Ministry of Labor, the Ministry of Finance and other departments jointly issued the "About Revising the Scope of Occupational Diseases and the Treatment Measures for Occupational Disease Patients" "Regulations", in which "pneumoconiosis of electric welding operators" is officially identified as an occupational disease. Welding operations are widely used in construction, machinery, shipbuilding and other industries. During the welding process, the welding rod and the metal material mel...

Problems solved by technology

Li Xiangguo disclosed the patented technology of "Protective Clothing for Oil Well Pipeline Electric Welding Leakage Repair" (ZL 201410011934.5). The core device is a filter cartridge with built-in adsorption particles, but the comfort is poor

Wen Haicai disclosed the patented technology of "a back-suction composite dust filter mask" (ZL 201420335535.X), which uses filter cotton and activated carbon to filter, and humidification can make the respiratory air flow more ideal, but its complicated filter and dust removal increase Improve the overall quality, thereby increasing the burden on workers

[0007] In summary, the existing dust masks have problems such as low purification efficiency and uncomfortable use.
