Portable air purifier

Abstract

The invention relates to a portable air purifier. An air filtration and purification unit which at least comprises one or more filter elements, a fan and an air speed control unit are arranged in the shell of the purifier, wherein air is absorbed from an air inlet at one end of the shell by using the fan; most harmful foreign matters in the air are filtered out and purified by using the air filtration and purification unit so as to obtain air with high purifying effect; the purified air is led out from an air outlet at one end of the shell; the air outlet is connected with a duct; and the other end of the duct is provided with a nostril plug capable of being inserted and sleeved in nostrils, so that the air speed of the purified air can be regulated in a driving mode or in an automatic or manual mode by using the air speed control unit, the purified air is directed led in the nostrils under appropriate air pressures, and users can easily breath pure air. Due to the design, the portable air purifier can be used for sporters, patients, pedestrians, outdoor activity personnel, persons living or working in epidemic areas, medical personnel, fire fighters and militaries and the like.

Description

technical field [0001] The present invention relates to an air purifier, especially an air filter purification unit including at least one or more filter elements, a fan and a wind speed control unit arranged in the housing of the purifier. The air inlet is inhaled, and most of the harmful foreign substances in the air are purified and filtered through the air filter unit, and the air with high purification effect is obtained. The purified air is exported from the air outlet at one end of the shell, and the A catheter is assembled, and the other end of the catheter is provided with a nostril plug that can be inserted into the nostril, and then the purified air can be actively adjusted by the wind speed control unit in an automatic or manual manner. Under the appropriate wind pressure, it is directly introduced into the nostrils, and the user can easily breathe pure air, which can be used for athletes, pedestrians, outdoor activities, people working and living in epidemic areas...

Problems solved by technology

[0003] For a long time, in order to avoid inhaling polluted and harmful air, in addition to various air filtration and purification equipment used indoors, most of the outdoors and public places wear masks to avoid inhaling polluted and harmful air or air-dispersed epidemics. Viruses, and there are quite a lot of types of masks, which vary according to the required use and requirements. They are divided into general use, medical use, industrial use, epidemic area use and fire use, etc., and the price varies according to the grade. Different, but although wearing a mask can prevent inhalation of polluted harmful air or airborne epidemic viruses, in fact, the effectiveness of masks to prevent inhalation of polluted harmful air is quite limited, and when worn because of the airtight barrier In this way, the wearer must inhale hard to get enough air, which will cause discomfort when wearing it, especially in places with poor air quality or scarce air, the wearer will feel uncomfortable due to stuffy heat and insufficient air. Also because of the long-standing problems of masks
