Cap type air purification device

Abstract

The invention discloses a cap type air purification device. The cap type air purification device comprises an air purification layer, an air supply power mechanism, a flow guiding enclosure assembly and a functional cap, wherein the air purification layer is composed of a multi-effect filter net and a harmful gas adsorption layer, and the air purification layer, the air supply power mechanism and the flow guiding enclosure assembly are integrally integrated on the functional cap. The air purification layer is fixed to the top and/or the surrounding position of the functional cap in the form of a window. The air supply power mechanism is provided with a mini-type draught fan, a battery and an adjusting switch, the mini-type draught fan and the battery are fixed in a cavity of a cap cover or the battery is externally hung on the arm or around the waist. The flow guiding enclosure assembly is provided with a flow guiding chamber, an eyebrow front observation window, a neck protecting flow guiding cover and a cap skirt. The cap type air purification device can effectively filter PM2.5 and harmful gases and is simple in structure and small and exquisite in size, the attractiveness, the dynamic sense and the modern sense of outdoor wearing products are improved, the situations of difficult breathing and discomfort due to wearing of a mask outdoors are avoided, and the using cost is low.

Description

technical field [0001] The invention belongs to the field of haze protection in the downstream or terminal of the haze control technology chain, and in particular relates to a cap-type air purification device. Background technique [0002] Fog, according to the "Sui Shu · Tianwen Zhixia" article "turns rain into fog if it doesn't rain". The concept of modern fog is "a group of micron-sized water droplets condensed by saturated water vapor floating in the air near the surface". For thousands of years, it has only been intermittently exposed to pure fog for a short time, and has no obvious harm to human beings. [0003] Haze is different from fog. According to "Erya · Shitian", the ancestor of Chinese dictionaries written before and after the Warring States period, "the wind and the rain make the soil a haze". However, due to the impact of emissions from modern industrial civilization, the concept of haze has evolved into "any one or more of sulfur dioxide and its sulfates, n...

Problems solved by technology

These technologies all have a common structural feature, which is composed of three loose and discrete units of "mask, air duct, and power purification adjustment assembly". Although the Chinese Patent Publication No. CN205547787U is also designed as an anti-smog travel bag, the integration degree is relatively high , compact structure, but too heavy, not co
