Description

an air purification device

technical field

The utility model belongs to the technical field of air purification, in particular to a portable air purification device.

Background technique

In 2013, "smog" became the keyword of the year. In January of the same year, 4 times of smog covered 30 provinces (autonomous regions and municipalities). In Beijing, only 5 days were not smog days. According to a report, less than 1% of the 500 largest cities in China meet the air quality standards recommended by the World Health Organization. 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 included health-threatening haze weather in the 2013 natural disaster situation for the first time.

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

At present, there are two main categories of personal protective equipment or air filtration and purification products for smog on the market, namely anti-smog masks and anti-smog helmets equipped with micro air purifiers.

Existing anti-smog products have the following disadvantages:

(1) Poor ventilation performance, obstructed breathing, long-term wearing can easily lead to dizziness, severe suffocation, life-threatening, such as N95 masks, should not be worn for a long time;

(2) The fit between the mask and the face is not tight, especially at the bridge of the nose. Although some masks have built-in metal shaping sheets at the joint, the airtightness is still poor. Even if the breathing resistance is not large, the joint between the mask and the face The gas itself is leaky, and the gas inhaled by the nostrils largely comes from the external space. Wearing a mask is just an illusion, and it cannot really remove the effect of smog or PM2.5;

(3) Long-term wearing has poor exhaust, and the nasal space is humid and stuffy;

(4) The currently disclosed anti-smog mask technology cannot take into account both good airtightness (to prevent direct inhalation of external unclean air) and good air permeability;

(5) Anti-smog helmets equipped with miniature air purifiers, such as the published utility model patents CN201320836424.2 and CN201320836671.2. The disclosed technology is to miniaturize the existing household photocatalyst air purifier and place it on the helmet In fact, this technology is a very superior technology, but it still has the following disadvantages: insufficient ventilation, complex structure, high cost, inconvenient portability, and energy supply.
