Cloud mask with PM2.5 sensor

Abstract

The invention relates to the technical field of daily necessities, in particular to a cloud mask with a PM2.5 sensor. The could mask comprises a surface cover, filter cotton, an outer shell, a rear cover and a silica gel shield, wherein the middle part of the outer shell is provided with a through hole, two ends of the through hole are respectively provided with a buckle; a filter cotton cover is connected with the outer shell by virtue of the buckles; the filter cotton is clamped in a groove between the filter cotton cover and the outer shell so as to form a filter layer; the surface cover covers the front end of the filter cotton cover and is connected with the outer shell by virtue of a magnet; the left and right sides of the outer shell are respectively provided with a pull switch controlled by an ear hook; the rear part of the outer shell is provided with the rear cover; the middle part of the rear cover is provided with a fan which serves as a vent hole; the PM2.5 sensor is arranged below the fan; the silica gel shield with a breather valve is clamped at the rear end of the rear cover. The cloud mask has functions of air purification, reinforced dedusting, sterilization and smell removal, assisted breathing and strong filtration, and is capable of detecting the air quality in real time on site.

Description

[technical field] [0001] The invention relates to the technical field of daily necessities, in particular to a cloud mask with a PM2.5 sensor. [Background technique] [0002] At present, protective masks on the market include cartoon cotton masks, ordinary degreasing gauze masks, disposable non-woven masks, activated carbon masks, industrial dust masks, PM2.5 masks, etc. [0003] (1) Cotton masks: basically only have the function of keeping warm and cold, the surface of the masks has large pores, and cannot resist particles with a particle size of only 2.5 microns, and some cotton masks have relatively large airflow resistance, which can easily cause breathing difficulties after wearing them; [0004] (2) Gauze mask: The pores are large, and the tightness on both sides of the nostrils is poor. The gauze mask can block larger particles through mechanical barriers layer by layer, but it is ineffective for PM2.5 particles. The thicker the mask, the poorer the air permeability,...

AI Technical Summary

Problems solved by technology

[0003] (1) Cotton masks: basically only have the function of keeping warm and cold. The airflow resistance is relatively large, and it is easy for people to have difficulty breathing after wearing it;

[0004] (2) Gauze masks: the pores are large, and the tightness on both sides of the nostrils is poor. The particulate matter is blocked, but it is ineffective against PM2.5 particulate matter. The thicker the mask, the poorer the air permeability. If you do not pay attention to hygiene, it will also breed bacteria;

[0005] (3) Activated carbon mask: Since activated carbon has the function of removing peculiar smell, the protective efficiency of particulate matter has not been significantly enhanced; at the same time, activated carbon itself is also a kind of particle, which has May be inhaled by the wearer, which is a hazard for patients with chronic respiratory diseases or the infirm;

[0006] (4) Disposable masks are mainly used to filter exhaled air to prevent infection between doctors and patients. The edge of the mask is not designed to fit the face shape. It can only play a blocking role, and cannot effectively resist PM2.5 particles

[0009] Traditional mask products have large pores and cannot resist particles with a particle size of only 2.5 microns, and some cotton masks have relatively high airflow resistance, which can easily cause breathing difficulties after wearing them. Hazard to the body of patients with respiratory diseases or infirm

However, the existing industrial masks and PM2.5 masks on the market mainly have low filtration efficiency, poor air permeability, poor wearing fit, easy breeding of harmful microorganisms on the filter material, secondary pollution and other pollution problems, and cannot kill the human body. harmful bacteria in exhaled air
