Tubular air cleaner

Abstract

The invention discloses a tubular air cleaner and belongs to household appliances. The tubular air cleaner is characterized in that an outdoor air outlet is formed between a wall and a guiding cover, an indoor air exhaust air outlet is formed in the middle of the drainage cover, a control module is installed at the lower end of the outdoor air outlet, the periphery of an outdoor air inlet passage is the wall, an indoor air exhaust passage is nested on the inner periphery of the outdoor air inlet passage, the diameter of the indoor air exhaust passage is one fourth that of the outdoor air inlet passage, the outdoor air outlet is formed in the left side of the outdoor air inlet passage, an upward bended opening which forms a 90-degree angle is arranged in the right side of the outdoor air inlet passage, a turbo-fan is arranged at the upper end of the bended opening, and a filtering membrane system, a primary filtering system and a hemispherical protective cover are sequentially nested in the periphery of the turbo-fan. The right end of an indoor air exhaust air inlet is connected with the indoor air exhaust passage, a downward bended opening which forms a 90-degree angle is formed in the right end of the indoor air exhaust passage, and the lower end of the bended opening is the indoor air exhaust air outlet. The filtering membrane system is provided with an ultraviolet sterilization lamp, an HEPA efficient filtering membrane and an activated carbon filtering membrane from inside to outside in sequence. The tubular air cleaner solves the difficult problems of filtering and exchange of indoor air and outdoor air and is widely applied to daily families and the like.

Description

technical field [0001] The invention relates to an air purifier, especially an air purifier capable of exchanging and filtering indoor and outdoor air. Background technique [0002] Air purifiers are home appliances used to purify indoor air. Generally, there are two types of central air-conditioning air purification devices and stand-alone units. They mainly solve indoor, underground space, and car air pollution problems 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 an internationally recognized method to improve indoor air quality. [0003] Domestic air, especially in big cities, has more than 250 days of hazy weather 365 days a year, especially the PM2.5 particles in the haze are very harmful to the human body. If the weak body inhales such particles for a long time, it can cause lung cancer, blood vessel blockage, etc...
