Head-wearing type air purification respirator

Abstract

The invention discloses a head-mounted air-purifying respirator, which belongs to a personal respiratory protection device and is composed of a miniature air purifier, a head clip device, an air delivery hose, an elastic device, and a nasal aspirator. The back of the air purifier is connected to the head clip The device, the elastic device is compounded on the air hose, and the two ends of the air hose are connected with the air purifier and the nasal aspirator; the nasal aspirator includes a hollow body, and the upper side is juxtaposed with two nasal suction pipes with soft sealing skirts on the outer periphery , the front side is provided with an exhaust port and a one-way diaphragm is installed in front of the exhaust port, and the side is provided with an air inlet connected to an air hose; the device is fixed on the head by using the mechanical action of the elastic device and the head clamp device The nasal aspirator is sealed and attached under the nostrils, which solves the problems of air leakage, occlusion, hot flashes, mixed breathing, and activity restriction of mask-type respirators. It is comfortable and invisible to wear, and is suitable for indoor and outdoor advanced respiratory protection; it is equipped with negative oxygen ions and an audio unit that creates high-quality purified air resembling a forest composition, and you can also enjoy music broadcasts.

Description

technical field [0001] The invention relates to a personal respiratory protection device, especially an air-purifying respirator worn on the head, which is suitable for individuals to purify and protect particulate matter, other pollutants and smog in the air under dynamic or static conditions, and to protect people's health. Breathe healthy. Background technique [0002] Since the beginning of industrialization, the atmosphere on which human beings depend has been polluted and destroyed by industrial emissions, and it has become increasingly serious in recent years, especially in cities where most of the air has deteriorated severely; modern science has proved that not only most of the particulate matter in the air contains its own Toxic substances, and also carry microorganisms such as bacteria and viruses, which spread diseases and harm human health. What's more serious is that fine particles such as PM2.5 or less can directly enter the human alveolar tissue, causing more...

Problems solved by technology

[0005] The problem to be solved by the present invention is to overcome the deficiencies of the above-mentioned technologies, and provide an air-purifying respiratory protection device for wearing on the head. The mutual mechanical effect of the device makes the device fixed on the head as a whole and the nasal aspirator is sealed and attached under the nostrils to solve a series of problems such as air leakage, face covering, hot flashes, mixed breathing and inconvenient activities of the mask respirator. At the same time, the negative oxygen ion generator and audio circuit have been added to expand the health care function and vocal music information function. The various variants of the head card device have opened up a variety of wearing modes and are suitable for people with different levels of characteristics. They can replace or Upgrade most types of face mask respirators and face masks
