Gauze mask type air filter

Abstract

The invention provides a gauze mask type air filter which comprises a gauze mask body and an air filter body sealed in the gauze mask body. The air filter body comprises a filtering bin with an air inlet tube, an air exchange bin with an air outlet tube and a communicating tube arranged between the filtering bin and the air exchange bin, wherein the upper portion of the filtering bin is provided with a miniature self-priming atomizing pump and a dry cell pack for providing a working power supply. The gauze mask type air filter produces the Lenard effect by adding the miniature self-priming atomizing pump, namely releases a large amount of negative oxygen ions to enable harmful gas, viruses, bacteria, fine particulate matter, dust and other impurities in the air to be killed and precipitate in water so as to purify the air. The gauze mask type air filter further has the effect of a negative oxygen ion generator, the air filtered by the filtering bin can contain ecological negative oxygen ions equivalent to natural negative oxygen ions, the concentration of the negative oxygen ions can be more than 10-30 thousands per cubic centimeter, and the produced negative oxygen ions can be beneficial to body health.

Description

technical field [0001] The invention relates to the technical field of air purification, in particular to a mask type air filter. Background technique [0002] At present, air pollution caused by environmental damage and industrial waste gas has become a major problem facing our country. The "dust" in spring and summer and the "smog" in autumn and winter have seriously endangered people's health, especially the winter smog is known as the "winter killer". Pollutants such as fine dust, suspended particles, bacteria and viruses make the PM2.5 index in the atmosphere seriously exceed the standard. In daily life and travel, these substances will affect the human respiratory tract. People who are exposed to smog for a long time may cause respiratory infection, acute tracheobronchitis, pneumonia, asthma attack, and induce or aggravate chronic bronchitis, especially in children. The mucous membranes of the nose, trachea, and bronchi of the respiratory tract are tender, and the nu...

Problems solved by technology

This prior art filters the space through liquid water, so that impurities such as harmful gases and dust in the air are deposited in the water, but it cannot effectively treat fine particles in the air and kill bacteria and viruses in the air, nor can it produce a large amount of Negative oxygen ions, and sometimes due to the presence of water, are more conducive to the growth and spread of bacteria on the filter screen
