A portable air purifier against smog

Abstract

The invention discloses a portable air purifier against smog, which comprises a breathing mask, an air filter device, an intake nasal plug sheath and an air supply mechanism. The upper end of the breathing mask is connected with the air supply mechanism through a telescopic mechanism. The air supply mechanism includes a The air chamber and the driving mechanism arranged in the air supply chamber, the breathing mask communicates with the inner cavity of the power chamber through the first corrugated hose, the diameter of the first corrugated hose gradually decreases, and the upper ends of the left and right sides of the air supply chamber are symmetrically arranged with The air filter device, the invention not only avoids excess gas in the respirator mask causing the wearer to be stuffy and humid, but also avoids the wearer's increased oxygen demand during exercise, which causes the wearer to breathe poorly and suffer from hypoxia At the same time, Chinese herbal medicine can be put in the Chinese medicine box, and the purified air will be absorbed by the human body under the action of Chinese medicine, and it will clear the lungs, moisten the throat and refresh the mind of the wearer, and it has a good sealing effect and is easy to carry , Wearing safety features.

Description

technical field [0001] The invention relates to the technical field of air purifiers, in particular to a portable air purifier against smog. Background technique [0002] The harm of polluted air to human body has aroused great concern of people. For air pollution, air purification masks have appeared on the market today, which are convenient for people to wear when they go out. However, the existing air purification masks are divided into three categories, one is ordinary masks, the other is nasal air purifiers, For example: the nasal air purifier with the Chinese patent authorization announcement number "CN 203852761U", one type is a mask with an air supply system, for example: a wearable air purifier with the Chinese patent application publication number "CN108201664 A" , yet the above two face shields also have the following problems: [0003] (1) Nasal air purifiers can only inhale through the nostrils and exhale through the mouth. When the wearer is exercising, he br...

Problems solved by technology

[0003] (1) Nasal air purifiers can only inhale through the nostrils and exhale through the mouth. When the wearer is exercising, he breathes frequently and requires a large amount of oxygen. It is not enough to inhale only through the nose Yes, it will cause the wearer to suffer from hypoxia. At the same time, when the wearer's mouth is hypoxic, he will unconsciously use his mouth to breathe, which will cause unfiltered air to be directly sucked into the body through the mouth, thus Causes nasal air purifiers to lose their filtering effect

[0004] (2) The title of the above patent is "a wearable air purifier". The shell of the wearable purifier is equipped with a power supply for the electric fan, which not only wastes power resources, but also has safety problems such as electric leakage when the wearer wears it.

[0005] (3) Ordinary masks are worn directly on the wearer's face, which not only has poor air purification effect, but also causes stuffiness and humidity in the mask when worn for a long time
