Built-in negative ion air purification device for air flue and installation method thereof

Abstract

The present invention relates to a built-in negative ion air purification device for air flue and an installation method thereof. The device includes an air flue pipe, a negative ion generator body, a negative ion emission head and a good conductor member. A grid member is arranged at the outlet position of the air flue pipe; the negative ion emission head is located behind the grid member; the tip portion emission part extends into the air flue pipe through the side wall of the air flue pipe; the good conductor member is arranged in the air flue pipe, and at the position between the negative ion emission head and the grid air port and near the grid member; a safety guide distance between the good conductor member and the negative ion emission head is 3-8 cm; and a ground wire is connected to the bottom of the good conductor member. The device has the advantages of a large amount of negative ions production, high purification speed and good security performance; and the built-in structure does not affect the outer appearance of the air flue. The device, an air conditioner filter and an air conditioner ventilation system form a complete super air purifier system, which gives the users brand new concepts and experiences of indoor air purification.

Description

technical field [0001] The invention relates to a negative ion air purification device, in particular to an air duct built-in negative ion air purification device and an installation method thereof. Background technique [0002] After the smog weather has become the norm, the people's attention to air quality is particularly high. Various types of air purifiers have appeared in the country. The current air purifiers are mainly divided into two categories: one is the filter-type vehicle-mounted air purifier The other is active air purifiers, silver ion technology, negative ion technology, low temperature plasma technology, photocatalyst technology and net ion group ion technology. The principle of negative ion sterilization and air purification technology is that after the combination of negative ions and bacteria, the bacteria will change their structure or transfer energy, resulting in the death of the bacteria, and finally due to gravity, they will fall to the ground, cau...

AI Technical Summary

Problems solved by technology

It has the following problems: first, the air purification in the car can only be completed after a long time after the car is started, and the purification speed is slow, and the short-distance driving cannot achieve the purification effect and cannot meet the needs of passengers.

Second, due to its backward technology and design defects, it is difficult for ordinary negative ion air purifiers to avoid the generation of derivatives such as ozone and positive ions when negative ions are generated.

Third, because the principle of the negative ion generator is to generate negative ions when the air is broken down by high-voltage DC electric field discharge, and a corona field will be generated around the periphery of the DC electric shock needle, in the negative ion generator, it must be Extremely high-voltage direct current, the higher the direct current voltage, the corresponding corona field range will also expand. When the spherical diameter of the corona field is larger than the diameter of the vehicle air duct, it is easy to produce a series of ionization after the high-energy electrons break through the air duct. and excitation, problems that may affect the control system of the car's internal circuits

Fourth, when negative ions are blown out from the grid parts of the air duct, different grid parts and chrome-plated parts will be used for different types of air ducts. In humid environments, the grid parts and chrome-plated parts will absorb negative ions. The negative ions at the grid part and the negative ions at the negative ion generating device generate an electrostatic field that is almost equal to the voltage of the emitter to repel the negative ions. The negative ions at the negative ion generating head are under the action of the electrostatic field strength at the grid part. It is difficult to be blown out of the grille, and the purification effect is poor

In addition, under high humidity conditions, there will be a crackling sound of creepage phenomenon, which will affect the user's experience and comfort.

Fifth, when people stretch their hands to the grille (especially the chrome-plated decorative part of the negative ion air outlet), the negative ions gathered at the grille will appear to be beaten, and the safety performance is poor

The external negative ion purifier takes up space in the car, and the interior effect of the car is not good

Sixth: If a high-concentration negative ion device is simply placed at the air outlet of the fresh air system, a super strong electrostatic field will be formed near the air outlet, and this corona electrostatic field will quickly absorb a large number of micro particles and quickly produce a Black precipitation phenomenon, affecting the decoration of the home

Seventh: If this super-concentration negative ion technology is simply added to the air outlet of the mobile air purifier, it will have a strong electrostatic effect on the control panel, and it will cause the controller with a LCD panel to produce a blurred screen, which greatly reduces customer The experience effect and unsafe hidden dangers
