Description

Technical Field

[0001] The utility model relates to the technical field of protective equipment, in particular to an auxiliary protective device for spraying dust. Background Art

[0002] Spraying is a coating method that uses a spray gun or a disc atomizer to disperse the spray into uniform and fine droplets by pressure or centrifugal force and apply it to the surface of the object to be coated. The protective mask is used to protect the face from flying metal debris, harmful gases, liquid splashes, metal and high-temperature solvent droplets. When workers are performing spraying operations, they usually need to use protective masks to protect their faces from harmful gases in the spraying operation. However, during the use of existing protective masks, the filter element part used to filter the air is mostly screwed in. The filter element is fixedly installed inside the air intake pipe by a bolt, which makes it inconvenient to disassemble the filter element and thus inconvenient to replace the filter element. Secondly, since the smoke generated when spraying dust is large, in order to facilitate the staff to observe the spraying area, a radiator is usually set on the protective mask to irradiate the spraying area, thereby increasing the brightness of the spraying area. However, since the radiator is also inconvenient to disassemble, it is also inconvenient to replace the radiator after it is damaged due to collision and other factors, which is not conducive to use. Therefore, an auxiliary protection device for spraying dust is proposed. Utility Model Content
