Gas purification device, multifunctional electronic respirator and dust cup

Abstract

The invention relates to a multifunctional electronic respirator. The multifunctional electronic respirator comprises a gas purification device. The gas purification device comprises at least one corona field for generating high-voltage static electricity, wherein the corona field is generated by applying certain high-voltage direct current between at least one corona wire serving as a negative electrode and an electric conductor serving as a positive electrode, and is provided with an air circulation channel for introduction and discharging of air, so that air which flows into the corona field from the air inlet side of the air circulation channel is purified by static electricity and then flows out from the air outlet side of the air circulation channel, the air outlet side is provided with an adsorption filter screen which is made of electric conduction materials, used for the flowing out of air entering the corona field and provided with an active surface, and after high-voltage direct current is applied on the electric conductor and the corona wire, the adsorption filter screen has positive charge with polarity same as that of the electric conductor. The gas purification device can filter and intercept particles, also can absorb small particles, and meanwhile can adsorb gaseous pollutants so as to be good in purification effect.

Description

technical field [0001] The invention belongs to the technical field of air purification, and in particular relates to a gas purification device, a multifunctional electronic mask and a dust collection cup for a low wind resistance vacuum cleaner. Background technique [0002] Preventing and controlling air pollution is an arduous and long-term task facing mankind. With the development of science, various purification technologies are maturing day by day. For particulate and gaseous pollutants, commonly used methods are as follows: [0003] 1. Inertial dust removal [0004] A technology that uses the inertia of motion of particles to separate them, such as cyclone separation. The equipment structure is simple and the cost is low. But it is only effective for particles with large diameters (above 100 microns). [0005] 2. Filtration and dust removal [0006] Let the air flow pass through the filter material at a certain speed. The filter material is generally porous, th...

AI Technical Summary

Problems solved by technology

[0010] However, electrostatic purification also has shortcomings: (1) No purification ability for gaseous pollutants

Even so, there are still some particles that cannot be attracted, so that the purification rate cannot reach 100%.

(3) The particles that can be attracted by the anode are limited and must be removed at any time, especially the particles with high resistance ratio accumulated on the surface of the anode will weaken the conductivity of the anode and lose its purification ability

(4) While high-voltage static electricity produces negative ions, it also produces a certain amount of ozone. Although ozone can sterilize and oxidize and decompose some organic gas molecules, it is harmful to the human body if it exceeds a certain concentration.

(1) Uncomfortable to use, the better the filtering effect, the greater the breathing resistance

(2) Inconvenient to use, especially when frequent speech is required

(3) Cotton or fiber masks will have peculiar smell after long-term use, and bacteria are easy to breed

(5) It can only partially protect the nasal cavity and oral cavity (because the mask cannot completely and tightly cover it), and cannot prevent the impact of pollen, dust and polluted air on the eyes, ears and other exposed parts of the head

(6) Some devices (such as patents with patent numbers 200620093467, 200620108326 and 972421174) are too large and heavy to carry

(7) Inconvenient to wear, seriously affecting the appearance

(9) The so-called electrostatic filtration uses materials such as melt-blown non-woven fabrics with static electricity, which is not a real electrostatic field, and it is impossible to have a continuous electrostatic filtration effect
