Wearable air purification device

Abstract

The invention provides a wearable air purification device. A mask is attached to the face of the human body to form a sealed air chamber covering the mouth and nose of the human body, the mask comprises a filter, a single-way valve, an adjustment valve and a heat-moisture exchanger from the environment side in sequence, and a moisture absorption material is arranged in an expiration channel of theheat-moisture exchanger and can absorb heat or discharge heat; an inspiration channel simultaneously achieves heat-moisture treatment until comfortable temperature and humidity parameters of the human body are achieved. The wearable air purification device is convenient to carry and wear, temperature and humidity adjustment can be conducted without energy consumption, and the problems are solvedthat a traditional gauze mask is stuffy, and filtering materials are wasted; the situation is also avoided that an existing portable air purification device is not suitable for motion. The system is low in weight and cost, and a user can enjoy comfortable breath.

Description

technical field [0001] The invention relates to a wearable air purification device, in particular to a wearable air purification device which can adjust temperature and humidity without energy consumption. Background technique [0002] With the development of the economy, the air pollution has become more and more serious. At present, more than 80% of the cities in my country have frequent smog. The health of the Chinese people has been violated, seriously affecting the quality of life, and even threatening the survival of human beings. Wearable air purification devices have undoubtedly become the main means of response. [0003] The airtight environment created by the current wearable air purifier has many defects in dealing with the high-heat and humid air exhaled by the human body and the temperature and humidity parameters of the inhaled air. Based on the physiological metabolic function of the human body, the gas exhaled by the human body is basically stable at 32°C, a...

AI Technical Summary

Problems solved by technology

The exhaled air with high heat and humidity will cause at least the following problems. The exhaled hot air will condense when it is cold, making the airtight environment become stuffy and humid. The water vapor will easily soak the filter material of the purifier, making it more stuffy and even invalid, and the comfort will immediately decrease; if you wear glasses , the exhaled heat will also cause the lens to blur, affecting safety

Furthermore, the air temperature and humidity parameters inhaled by the environment are quite different from the comfortable environment and even the indoor environment, which will cause obstacles and difficulties to the normal breathing of the human body, further reduce the comfort of human breathing, and even cause harm.

In addition, passive temperature and humidity control measures use heat and moisture exchange materials to alternately pass inhalation and exhalation, which cannot guarantee the effect and can only be used as an auxiliary measure. Inhalation and exhalation are completely mixed, and the flow is disordered and polluted each other; Using electric drive for heating and cooling requires additional energy, the weight of the battery is heavy, the body load increases, and the comfort level is reduced. It is not suitable for walking or exercising.
