Description

Capsule breathing device with sealing cover and sealing cover assembly thereof

Technical field

The invention belongs to the technical field of air purification, and particularly relates to a capsule breathing device with a sealing cover and a sealing cover assembly thereof.

Background technique

In 2013, “Haze” became the key word of the year. In January of the same year, four smog processes enveloped 30 provinces (autonomous regions and municipalities). In Beijing, only five days were not foggy days. According to reports, less than 1% of China's 500 largest cities meet the World Health Organization's recommended air quality standards. At the same time, 7 of the 10 most polluted cities in the world are in China.

On January 4, 2014, the National Disaster Reduction Office and the Ministry of Civil Affairs first reported the smog weather that was harmful to health into the natural disaster situation in 2013.

The most harmful component of smog is PM2.5. The inhalation of PM2.5 can directly damage the respiratory system and cardiovascular system, including respiratory tract irritation, cough, dyspnea, lower lung function, aggravation of asthma, and chronic bronchus. Inflammation, arrhythmia, non-fatal heart disease, premature death of patients with cardiopulmonary disease, lung cancer, etc. About 2 million premature deaths each year worldwide are related to particulate matter such as PM2.5.

At present, there are two main types of personal protective equipment or air filtration and purification products for smog, existing products on the market or open technical products, anti-fog masks and anti-fog helmets equipped with miniature air purifiers.

Existing anti-fog products have the following disadvantages:

(1) Protective mask products are poor in wearing comfort, heavy in weight, and not beautiful in appearance, and are not suitable for daily wear.

(2) Protective mask products have limited filtering area, poor ventilation and lead to respiratory obstruction. Wearing them for a long time can cause dizziness and severe suffocation, which is life-threatening. For example, N95 masks should not be used for a long time. Wear it.

(3) The mask and the face are not tightly attached, especially near the bridge of the nose. Although some masks have built-in metal shaping sheets at the fittings, the sealing is still poor, so a large part of the gas inhaled in the nostrils comes directly from the external space. It does not really play the role of air purification.

(3) The exhaustion is not smooth for a long time, the nasal space is damp and depressed.

(4) It is not possible to achieve good sealing (to prevent direct inhalation of external non-clean air) and good gas permeability.

(5) The life cycle of mask products is short, and it needs to be replaced in time when air pollution is serious, resulting in inconvenience and relatively high cost.

(6) An anti-fog helmet equipped with a micro air purifier, the existing household photocatalyst air purifier is miniaturized and placed on the helmet, but it still has the following disadvantages: insufficient purging ventilation, complicated structure, high cost, Inconvenient to carry, energy supply, etc.

Moreover, most of the respiratory masks used in the existing personal protective equipment for smog are only equipped with a filtering unit and no one-way breathing valve is provided, so that the exhaled exhaust gas is returned to the filtering unit, which affects the purity of the filtered air. Forming a dead space in the traditional sense, so long-term inhalation of exhaust gas will be detrimental to human health.
