Mouth mask type air purifier

Abstract

The invention relates to a mouth mask type air purifier which comprises a plastic front cover, an active carbon filter cotton and a blower fan are installed on the front cover, and the front cover is provided with an air intake and an air outlet column. A silicone sleeve is installed on the periphery of the front cover. The silicone sleeve when worn is attached to a face portion. The mouth mask type air purifier is designed into a mouth mask type structure to be directly worn on the face portion, and is convenient to use. The silicone sleeve is installed on the periphery of the front cover, and the silicone is flexible and increases the sealing performance when directly attached to the face portion. The main body structure of the entire purifier is mainly made of plastic and silicone, which substantially reduces the mass of the purifier, effectively reduces the burden of a user and improves the wearable experience. The mouth mask type air purifier is promising in market prospect.

Description

technical field [0001] The invention relates to the field of air purifiers, in particular to a mask type air purifier. Background technique [0002] With the rapid development of my country's economy, the air pollution caused by industry is becoming more and more serious. In recent years, the frequency of smog days is higher and the range is wider. The smog contains a large amount of sulfur dioxide, nitrogen oxides and inhalable particulate matter. etc., these substances have serious harm to the human body. [0003] The basic structure of the existing air purifier: the fan makes the air pass through the filter cotton net, activated carbon, electrostatic adsorption, titanium dioxide combined with ultraviolet light, and negative oxygen ions for combined purification, and chemically decomposes benzene and formaldehyde decoration pollution through liquid catalysts Treatment to reduce the presence of harmful ions in the air. Among these methods, only filters and activated carbo...

AI Technical Summary

Problems solved by technology

Among these methods, only filters and activated carbon are safe, effective and have no side effects. For example, electrostatic adsorption can produce oxygen ions with positive charges, and titanium dioxide and negative ions will produce strong oxygen, namely ozone. A large amount of adsorption has side effects on the body, and is only suitable for highly polluted, large-scale It is used in the space volume and combined with the normal outdoor ventilation environment to reduce the negative impact on the human body. It is not suitable for use when going out due to space restrictions.

[0004] Chinese patent (announcement date of CN103736220A announcement date 2014.04.23) discloses a portable air purifying respirator, including a portable air purifier and a mask. The air outlet of the portable air purifier is connected to the mask through a trachea. Although the device can be carried and used outside, it must increase the trachea. There are many inconveniences in carrying and using, and the disadvantages such as poor human body experience, so it is not easy to be popularized and used.
