Description

Technical Field

[0001] This utility model relates to the field of air purification technology, and in particular to a plasma air purifier. Background Technology

[0002] Currently, air purifiers on the market generally suffer from limited filtration efficiency and inconvenient maintenance. Traditional single-stage or two-stage filtration systems are prone to clogging due to particle accumulation, resulting in insufficient interception of fine particles. At the same time, the filters need to be frequently disassembled for cleaning or replacement, and some models require complete disassembly, which is cumbersome. In addition, dust can easily re-enter the air due to airflow disturbances after it has settled, posing a risk of secondary pollution and affecting the purification effect. Summary of the Invention

[0003] The purpose of this invention is to provide a plasma air purifier to solve the problems of limited filtration efficiency and inconvenient maintenance common in air purifiers.

[0004] This utility model achieves the above-mentioned objectives through the following technical solution: it includes a cylindrical outer shell, a top air outlet, and a base. The cylindrical outer shell is provided with a primary air inlet filter. The outer edges of the base and the top air outlet are both provided with threads and are engaged with the threaded grooves on the inner wall of the cylindrical outer shell. A middle partition is also horizontally installed inside the cylindrical outer shell. A microporous filter is installed below the middle partition. A limiting seat is provided on the inner side of the base. The bottom of the limiting seat is installed and connected to the base and separates the base into a dust storage chamber. A secondary air inlet filter is provided through the middle of the middle partition.

[0005] Furthermore, an exhaust fan, a bipolar plasma generator, and an ultraviolet light strip are installed inside the cylindrical outer shell cavity above the partition plate and are connected to the partition plate via a bracket.

[0006] Furthermore, the limiting seat includes a disc-shaped housing, and a columnar housing with an upward protrusion is fixedly provided in the middle of the disc-shaped housing. The outer diameter of the columnar housing does not exceed the inner diameter of the bottom of the microporous filter screen. A second cylindrical connector is fixedly provided at the bottom of the disc-shaped housing. The base is provided with a first cylindrical connector on the outside of the second cylindrical connector and is fixedly connected to it. The second cylindrical connector is connected to the threaded groove on the inner wall of the first cylindrical connector through the thread on its outer surface.

[0007] Furthermore, the area between the outer side of the first cylindrical connector and the inner wall of the base is a dust storage chamber area, and the area of ​​the opening area above the dust storage chamber is equal to the area between the inner wall of the cylindrical shell and the outer edge of the microporous filter.

[0008] Furthermore, the dust collection chamber can collect dust that falls off the microporous filter screen and prevent the dust inside from floating up through its disc-shaped shell.

[0009] Furthermore, the primary air inlet filter is an array of ventilation holes formed in the lower part of the cylindrical outer shell, and the secondary air inlet filter includes a cylindrical tube and ventilation holes formed on its surface.

[0010] Furthermore, the bottom of the tube is sleeved on the outside of the cylindrical shell and movably connected thereto, and the top of the tube passes through the middle partition and is fixed by screws.

[0011] Furthermore, two limiting rings are fixedly provided at the bottom of the partition plate, the top of the microporous filter screen is stuck between the two limiting rings, and the microporous filter screen is entirely sleeved on the outside of the tube and its bottom abuts against the disc-shaped shell.

[0012] Beneficial effects: This utility model is reasonably designed and has the following beneficial effects:

[0013] In this utility model, a multi-stage filtration system is set up. The first-stage inlet air filter intercepts large dust particles, the microporous filter further filters tiny particles, and the second-stage inlet air filter acts as the last barrier after the microporous filter is damaged, providing secondary filtration until the microporous filter is replaced. The dust collection chamber can collect the dust that falls from the microporous filter and prevent the dust inside from floating up through the disc-shaped shell. At the same time, it adopts a quick disassembly design. When cleaning, only the base needs to be unscrewed, without disassembling the whole machine, making maintenance convenient.

A secondary air inlet filter 6 is provided through the middle of the middle partition 102.

[0023] Among them, an exhaust fan, a bipolar plasma generator, and an ultraviolet light strip are installed inside the cylindrical outer shell 1 above the partition plate 102 and are connected to the partition plate 102 through a bracket.

[0024] The limiting seat 5 includes a disc-shaped housing 501, and a columnar housing 502 that protrudes upward is fixedly provided in the middle of the disc-shaped housing 501. The outer diameter of the columnar housing 502 does not exceed the inner diameter of the bottom of the microporous filter screen 4. A second cylindrical connector 503 is fixedly provided at the bottom of the disc-shaped housing 501. The base 3 is provided with a first cylindrical connector 302 on the outside of the second cylindrical connector 503 and is fixedly connected to it. The second cylindrical connector 503 is connected to the threaded groove on the inner wall of the first cylindrical connector 302 through the thread on its outer surface.

[0025] The area between the outer side of the first cylindrical connector 302 and the inner wall of the base 3 is the dust storage chamber 301 area. The opening area above the dust storage chamber 301 is equal to the area between the inner wall of the cylindrical shell 1 and the outer edge of the microporous filter screen 4.

[0026] The dust collection chamber 301 can collect the dust that falls from the microporous filter screen 4 and prevent the dust inside from floating up through the disc-shaped shell 501.

[0027] The primary air inlet filter 101 consists of an array of ventilation holes 602 located in the lower part of the cylindrical housing 1. The secondary air inlet filter 6 includes a cylindrical tube 601 and ventilation holes 602 located on its surface.

[0030] Working principle: When this utility model is in use, external air enters through the first-stage air inlet filter 101 in the lower part of the cylindrical shell 1, is filtered by the microporous filter 4, and then enters the upper chamber through the second-stage air inlet filter 6. The exhaust fan drives the purified air to be discharged through the top air outlet 2, forming a circulation.

[0031] The primary air intake filter intercepts large particles, the microporous filter intercepts tiny particles, and the secondary air intake filter acts as a redundant barrier. The filtered dust is deposited in the dust collection chamber 301, and the disc-shaped shell 501 prevents the dust from floating. During maintenance, it can be cleaned simply by unscrewing the base, avoiding secondary pollution.
