Intelligent mask with integrated functions of whistle and haze prevention

Abstract

The invention relates to an intelligent mask with integrated functions of a whistle and haze prevention. The intelligent mask comprises a shell, a sound production device, a breathing valve, an activeair supply module, a neck hanging type adjustable head belt and a sealing ring, wherein the sound production device is arranged on the inner wall of the mask and comprises a whistle, a sound-gathering sound production piece, an external sound amplifying shell and a fixing piece; the breathing valve is located on the shell and is connected with the interior of the mask and outside air; the activeair supply module comprises a decoration ring, a front cover, a replaceable filter element, an active air supply type rechargeable nanometer fan, a fixed pad, a module frame, a charging port and an adjusting switch; the replaceable filter element comprises a dust-free granular active carbon filtering layer and a nano-silver coating layer; the active air supply type rechargeable nanometer fan is fixed on the fixed pad and is connected with a shell charging port through an electric wire; and the sealing ring is tightly connected with the inner wall of the mask. The mask provided by the inventionprovides more comprehensive protection for a traffic police to whistle on a haze day, and the respiration intensity of the traffic police in whistling for a long time is reduced.

Description

technical field [0001] The invention relates to the technical field of protective products, in particular to an anti-haze mask capable of sounding and actively blowing air.
