Wearing-type fresh air ventilator with bionic lung function

Abstract

The invention relates to a wearing-type fresh air ventilator with a bionic lung function and belongs to the technical field of personal protective articles. According to the technical scheme, the wearing-type fresh air ventilator comprises a filter core, a draught fan, a bionic lung gas bag, a gas guiding pipe and a nose mask (face mask) and is characterized in that after gas is purified through the filter core under the effect of the draught fan, the gas enters the bionic lung gas bag, and then the gas is supplied to a user through the gas guiding pipe. The wearing-type fresh air ventilator has the advantages that various filter materials can be used for filtering and disinfecting gas containing different polluting components, and filtered gas is supplied to the nose mask (face mask) of the user through the bionic lung gas bag, so that breathing of the user is more close to be in a natural state, the wearing-type fresh air ventilator is more suitable for long-time using, and damage of the various polluting components to a human body is prevented to a great extent; and the wearing-type fresh air ventilator can be widely applied to environments such as the hazy weather, dust-exposed work, disaster resistance and danger rescue, public places and hospitals, and more safety guarantee and life convenience are provided for people.

Description

technical field [0001] The invention relates to a wearable fresh air fan, which belongs to the technical field of personal protective equipment. Background technique [0002] Air pollution will seriously affect our health, and wearable air purification equipment has defects in varying degrees. For example, wearing a protective mask for a long time will cause stuffiness or even hypoxia. Existing wearable air purifiers have excessive wind speed and instantaneous supply. The disadvantage of insufficient air volume is that people not only feel stuffy when using these devices, but also feel uncomfortable when the wind blows on their faces. Because an adult will inhale 500-1000ml of air every time he breathes, and the diameter of the air supply pipe of the wearable air purifier is usually less than 1.4cm. Since it takes about 3 seconds for a person to inhale each time, it takes about 3 seconds The wearer is supplied with 500-1000ml of clean air inside, and the air velocity in the...

[0002] Air pollution will seriously affect our health, and wearable air purification equipment has defects in varying degrees. For example, wearing a protective mask for a long time will cause stuffiness or even hypoxia. Existing wearable air purifiers have excessive wind speed and instantaneous supply. The disadvantage of insufficient air volume, people not only feel stuffy when using these devices, but also feel uncomfortable when the wind blows on the face

Because an adult will inhale 500-1000ml of air every time he breathes, and the diameter of the air supply pipe of the wearable air purifier is usually less than 1.4cm. Since it takes about 3 seconds for a person to inhale each time, it takes about 3 seconds The wearer is supplied with 500-1000ml of clean air inside, and the air velocity in the air supply duct usually reaches 2-4 meters per second, which is equivalent to the wind of about 3 levels continuously blowing the user's face, which will make the user very uncomfortable. It is uncomfortable, and because the original equipment does not have the buffer of the bionic lung airbag, it cannot provide 500-1000ml of clean air for the wearer in an instant in the case of direct supply from the pipeline, and the user will feel stuffy due to the lack of air supply in the moment. In view of this The invention came into being
