Pneumatic mask

Abstract

The invention discloses a pneumatic mask, comprising filter cotton, wherein the filter cotton is adhered to a first arc plate distributed with air holes; a second arc plate is arranged in front of the first arc plate; a bent backward arc opening is formed between the first arc plate and the second arc plate; a miniature fan is arranged in front of the second arc plate; and the place of the second arc plate corresponding to the miniature fan is densely distributed with through holes. The pneumatic mask not only can effectively filter paint smoke and dissipate the paint smoke in front of the mouths and noses of human bodies so as to further reduce the possibility that paint particles enter into mouths and noses.

Description

technical field [0001] The invention relates to the field of metal coating, in particular to a mask used for protection during workers' spraying operations, including filter cotton. Background technique [0002] For metal components, in many cases, the surface needs to be painted so that the surface of the metal component has good anti-corrosion performance and makes it more tidy and beautiful. For this reason, simple artificial painting or electrostatic spraying is usually used, and a spray gun is used to spray mist liquid paint, paint, or paint powder particles on the workpiece. During this process, the operator is in a large amount of paint smoke. , you will inhale a large amount of paint fumes and accumulate for a long time, which will cause serious damage to your health. Therefore, you must take protective measures; usually, you will wear a mask for protection; Layers of filter cotton are stacked. For this kind of mask, although most of the paint smoke can be filtered...

Problems solved by technology

For this reason, simple manual spraying or electrostatic spraying is usually used, and a spray gun is used to spray mist liquid paint, paint, or paint powder particles on the workpiece. During this process, the operator is in a large amount of paint smoke. , you will inhale a large amount of paint fumes, and accumulate for a long time, which will cause serious damage to your health. Therefore, you must take protective measures; usually, you will wear a mask for protection; For this kind of mask, although it can filter out most of the paint smoke, however, due to the uneven size of the paint particles, there are still some tiny paint particles that can enter the mouth and nose of the human body through the filter cotton. Therefore, its Filtering effect is still relatively limited
