Description

Breathing assembly used in cooperation with air purifier

Technical Field

The utility model relates to an air purification subassembly, in particular to breathing subassembly that cooperation air purifier used.

Background

With the continuous development of economy, the quality of life of people is continuously improved, and from the past, the people can satisfy the temperature and fullness to pay attention to the quality of life and health. The work is not only an important basis for providing basic guarantee for the life of people, but also the health and the safety of each person can be influenced by the quality of the working environment. However, at present, many working environments have influence on human health and safety, for example, painters (including furniture spray painting and automobile paint baking rooms), stone or wood processing workers generally need to work in an air-polluted environment or an environment with high dust content, doctors and nurses can also work in a space containing a large amount of viruses in treatment and nursing of infectious patients, and in addition, some working environments containing toxic gases (natural gas, carbon monoxide and the like) exist. The workers in special posts work in various environments harmful to health pollutants for a long time, respiratory systems of the workers are directly invaded, respiratory diseases and physiological dysfunction can be caused, mucous membrane tissues such as eyes and noses are stimulated to be diseased, the workers are in serious air pollution environments all year round, diseases such as chronic bronchitis, bronchial asthma, emphysema and lung insufficiency can be caused, lung cancer can be caused seriously, and the body of people is seriously damaged.

In order to protect the health and safety of workers, the individual protection of the respiratory system is aimed at specific personnel working in a polluted environment. At present, the antifog haze apparatus of well-known dust prevention is the simple type of gauze mask, face guard, filter paper mostly, relies on the human body to inhale the clean air after the filtration from the gauze mask to the air through filter paper, and these safeguard procedures all are direct to the contaminated air in the work environment filters and realize safeguard function, and the filtration requirement to gauze mask or face guard just is very high like this, and a lot of ordinary gauze masks can't reach the filter effect. For example, the gauze mask is most commonly used, the dust blocking rate is generally not even 30%, the dust prevention effect cannot be achieved at all, some filtering type anti-particle masks and the like can be provided, although the gauze mask has a certain filtering effect compared with the gauze mask, the filtering type dust prevention masks, the masks and the like can directly enter some polluted air if the sealing effect is not good, but the sealing effect is good, the breathing fatigue of a user can be caused in a short time, particularly heavy physical labor is performed in work, the breathing is difficult, the covering is flustered, the working efficiency is greatly influenced, some people do not use, and the body is greatly injured. In addition, because the mask filters air in the pollution ring and is easily polluted, the mask needs to be replaced frequently, for example, during the period of coronary pneumonia, the mask needs to be replaced every 4 hours, and the mask can only filter particles and cannot filter peculiar smell gases and toxic gases, such as natural gas, carbon monoxide and other toxic gases.

In order to solve the problems, a positive pressure air supply respirator is invented, but the cost of most of the respirators is high, the selling price of a small portable respirator reaches about 1 ten thousand, the small portable respirator cannot be born by common workers, the respirators are also placed in a polluted environment to filter polluted air and then breathe, the filtering requirements are the same, the consumption ratio of a filter screen is high, the cost of the filter screen of the respirator is generally high, and the use cost can be greatly increased when the filter screen of the respirator is frequently replaced.

The air purifier is a mature air purification product at present, and has been widely used in ordinary families, and ordinary air purifier sellers only have a few hundred money and low cost, but the air purifier is mainly used for purifying indoor air and gradually purifying outdoor polluted air flowing into a room.
