Portable second-hand smoke purification device

Abstract

The invention discloses a portable second-hand smoke purification device, and relates to the technical field of smoke purification. The portable second-hand smoke purification device comprises a shell and an inner cavity formed by the shell, the shell comprises an upper shell and a lower shell, and a base is arranged at the bottom end of the lower shell; the inner cavity is divided into an upper containing cavity and a lower containing cavity communicating with the upper containing cavity, a structural part is arranged between the upper containing cavity and the lower containing cavity, and a detachable filter screen is arranged on the structural part; and a fan is arranged in the lower containing cavity, a catalyst module is arranged at the bottom of the lower containing cavity, an air inlet is formed in the top of the upper shell, and an air outlet is formed in the side wall of the lower shell and located between the catalyst module and the base. According to the portable second-hand smoke purification device, by arranging the catalyst module, oxygen in air is catalyzed and oxidized to generate free radicals with high oxidizing capacity, nicotine, ammonia and other harmful gases are rapidly oxidized and decomposed, harm of second-hand smoke to a human body is reduced, and the portable second-hand smoke purification device is simple in structure, convenient to operate and high in practicability.

Description

technical field [0001] The invention belongs to the technical field of flue gas purification, in particular to a portable second-hand smoke purification device. Background technique [0002] Smoking is harmful to humans in many ways, mainly causing asthma, pneumonia, lung cancer, high blood pressure, heart disease and reproductive dysplasia. Among them, second-hand smoke is more harmful to passive smokers than active smokers, especially to children. [0003] At present, household or large-scale air purifiers are mostly used in public places to purify second-hand smoke. On the surface, the air purifier can purify the smell of second-hand smoke, but there are major defects in its application process, which are mainly manifested in two aspects: (1) The purifier is mostly used in a large space, and it needs to run for more than ten or even dozens of hours to achieve air pollution. The purification efficiency is low, and in actual operation, most of the second-hand smoke has be...

Problems solved by technology

[0004] At present, most of the purifiers on the market use activated carbon, ion / ozone technology, photocatalysis and other technologies, all of which have certain defects, such as the short life of activated carbon, the harm of ozone to the human body, the high requirement of light for photocatalysis, and low efficiency, etc.
