Breathing apparatus with bidirectional purification function

Abstract

The invention discloses a breathing apparatus with a bidirectional purification function. The breathing apparatus comprises a breathing apparatus body and an airflow drive element fixedly arranged inthe breathing apparatus body, wherein the breathing apparatus body comprises an upper breathing apparatus cover and a lower breathing apparatus cover; the upper breathing apparatus cover and the lowerbreathing apparatus cover form sealing matching, and the interiors of the upper breathing apparatus cover and the lower breathing apparatus cover are matched to form a filter space; a filter materialused for realizing air filter is fixedly arranged in the filter space; the filter space is divided into an outer-layer filter space and an inner-layer filter space by the filter material; an intake port and an exhaust port are formed in the lower breathing apparatus cover; and the intake port and the exhaust port both communicate with the inner-layer filter space. The breathing apparatus disclosed by the invention is capable of separating the inhaled air of a user from the expired gas, and prevents the user from re-inhaling the expired gas, so that the breathing quality of the user is ensured. Meanwhile, the expired waste gas of the user is discharged after being filtered, so that the user and other people are protected.

Description

technical field [0001] The invention relates to a filtering device, in particular to a bidirectional purifying respirator capable of separating gas inhaled and exhaled by a user and realizing bidirectional filtering, and belongs to the field of air filtering equipment. Background technique [0002] In recent years, the problem of air pollution in our country has become increasingly serious. For the purpose of protecting health and preventing respiratory diseases, more and more people have begun to use electric filter respirators in their daily work and life. However, the common electric filter respirators currently on the market are only for filtering the air inhaled by the human body, but do not treat the exhaust gas exhaled by the wearer. In fact, the air exhaled by the human body also contains a large number of bacteria, especially in the autumn and winter seasons when colds are high. If the air is exhaled by a cold patient, the bacteria and viruses carried in the air wil...

AI Technical Summary

Problems solved by technology

[0004] 1. The existing electric filter respirator realizes the active air supply function, and what the user inhales is the air filtered through the filter, but most of these products do not reserve a large enough channel for the exhaust gas exhaled by the user, which leads to breathing problems. The outgoing air cannot be discharged in time, and then it is inhaled with the incoming new air, and so on, the carbon dioxide concentration inside the respirator increases, which greatly reduces the breathing quality of the user

[0005] 2. Most users think it is inconvenient to speak after wearing the respirator. On the one hand, the electric respirator itself has a certain noise when the fan rotates. On the other hand, the sound channel is small or not smooth, which will make the sound come out. Reduced efficiency

General indoor air purification equipment has a better filtering effect on larger particles, such as 2.5 micron and 0.3 micron particles, and also has a certain effect on bacteria, but has almost no effect on viruses
