An anti-smog (pm2.5) mask

Abstract

The invention belongs to the technical field of masks, in particular to an anti-smog (PM2.5) mask, comprising a body; two ends of the body are connected with buckles, and a metal frame is symmetrically pasted on the inner wall of the body. The inner end of the frame is connected with a baffle through the rotation of the torsion spring. The baffle is in a horizontal state under the action of the torsion spring and the positioning bar. The baffle can divide the interior of the body into two chambers, one of which is A pressure sensor is installed on one end of the sheet close to the center of the body, and a connecting pipe communicating with the inside of the body is installed on the outer wall close to the opening. The other end of the connecting pipe is connected to a trachea, and the other end of the trachea is connected to an air pump; the present invention By setting the air extraction mechanism inside the mask body, the exhaust gas discharged from the inside of the mask can be discharged quickly and efficiently, and at the same time, the air outside the mask can automatically flow into the inside of the mask, eliminating the need for the human body to inhale laboriously, which greatly reduces the user's fatigue. Difficulty breathing.

Description

technical field [0001] The invention belongs to the technical field of masks, in particular to an anti-fog (PM2.5) mask. Background technique [0002] Masks can generally be divided into air filter masks and air supply masks. It is designed for people's health and is used to prevent some visible or invisible substances that are harmful to the human body from being filtered, so that they will not have bad effects on the human body. Masks have a certain filtering effect on the air entering the lungs. Wearing masks has a very good effect when working in a polluted environment such as dust when respiratory infectious diseases are prevalent. [0003] There are also some technical solutions about anti-fog masks in the prior art, such as a Chinese patent with a patent number of 2014101578729, which proposes an anti-fog mask, which relates to the field of dust-proof technology, including a mask body, The two ends of the mask body are connected with buckle ear straps, and the buckl...

Problems solved by technology

[0004] But the mask in the above-mentioned technology blocks the gas exhaled in the nasal cavity, so that the exhaust gas exhaled by the human body is not easy to be quickly and effectively discharged from the inside of the mask, which easily causes the exhaust gas to be inhaled again by the human body, and the hot air flowing out from the top of the mask is easy to wear glasses The lens of the patient is blurred, which affects their vision. At the same time, the mask that fits closely to the face will also cause chest tightness and dizziness due to poor breathing during long-term use, which will affect the user experience of the mask.
