Problems solved by technology

[0002] As the population continues to increase, the population is becoming denser and denser. If a fire breaks out, it will bring certain difficulties to the rescue work of firefighters. Due to the obstruction of buildings, large-scale rescue equipment cannot be moved to the fire area. A large amount of toxic and harmful gases will be produced, so residents need to prepare some emergency escape breathing apparatus at home. The existing self-priming respirator generally includes a breathing mask and a filter cavity. In the mask, but the filter in the filter cavity will cause a large amount of dust particles to adhere to the filter if the outside smoke is relatively large when filtering, which will make the wearer's breathing difficult, which in turn will cause the wearer to have difficulty breathing. Quickly clean the soot particles attached to the filter, and the operation should be fast and convenient. In addition, it is necessary to adjust the size of the deposition space for the deposited soot particles

Abstract

The invention discloses a floating adjustable self-priming respirator, which includes a floating mechanism; the invention adds a floating mechanism, which drives the threaded orifice plate to float up and down by rotating the adjusting screw, thereby driving the annular floating tube to float up and down, and the annular telescopic tube The telescopic movement expands the accommodating space of the annular accommodating tank and increases the space for depositing soot particles.

Description

technical field [0001] The invention relates to a floating adjustable self-priming respirator. Background technique [0002] As the population continues to increase, the population is becoming denser and denser. If a fire breaks out, it will bring certain difficulties to the rescue work of firefighters. Due to the obstruction of buildings, large-scale rescue equipment cannot be moved to the fire area. A large amount of toxic and harmful gases will be produced, so residents need to prepare some emergency escape breathing apparatus at home. The existing self-priming respirator generally includes a breathing mask and a filter cavity. In the mask, but the filter in the filter cavity will cause a large number of dust particles to adhere to the filter if the outside smoke is relatively large when filtering, which will make the wearer's breathing difficult, which will cause the wearer to breathe hard, so it needs to be cleaned in a short time Quickly clean the soot particles attac...
