Through the wall purification ventilation pipe

Abstract

The invention discloses a through-wall purifying ventilating pipe. The through-wall purifying ventilating pipe comprises a ventilating pipe body and a filtering device. The ventilating pipe body comprises a first section ventilating pipe main body and a second section ventilating pipe main body. The filtering device comprises a filter net and a filter net mounting shell. The filter net mounting shell comprises two semi-mounting shell bodies of the same structures; outer threads are arranged at the two ends of the filter net mounting shell; a first mounting cover is arranged at one end of the first section ventilating pipe main body; and a second mounting cover is arranged at one end of the second section ventilating pipe main body. According to the through-wall purifying ventilating pipe,the cleanliness of the ventilating pipe can be maintained, the service life of the ventilating pipe is prolonged, the cost is saved, meanwhile, the use environment of an air purifier can be effectively improved, and the indoor air quality is improved; and the contact time of air and the filter net is prolonged by prolonging a filter channel of the filter net, and thus the purifying efficiency of the filter net is high.

Description

technical field [0001] The invention belongs to the field of gas purification and ventilation equipment accessories, in particular to a wall-penetrating purification ventilation pipe. Background technique [0002] Air purifiers refer to products that can absorb, decompose or transform various pollutants in the air and effectively improve the cleanliness of indoor air. It is used in home, medical and industrial fields. In the field of home, single-unit household air purifiers are the mainstream products in the market. The main function is to remove particulate matter in the air, including allergens, indoor PM2.5, etc., and it can also solve the problem of volatile organic compounds in indoors, underground spaces, and cars caused by decoration or other reasons. Due to the persistent and uncertain characteristics of the release of air pollutants in relatively closed spaces, the use of air purifiers to purify indoor air is one of the internationally recognized methods to improv...
