Description

[Technical Field]

[0001] This invention relates to air purifiers, and more particularly to a uniform filtration structure for use in air purifiers. [Background Technology]

[0002] Air purifiers filter impurities in the air to purify it. An internal fan supplies air, and a hollow cylindrical filter structure is installed during this process. Air permeates the filter before entering the fan, during which impurities are filtered out. Because the air inlet is located at a specific point on the filter, air molecules flow along a fixed path through it. This uneven filtration results in some parts of the filter having high filtration intensity while others have low filtration intensity. Consequently, when replacing the filter, frequently filtered sections may have reached their limit of filtration, while less frequently filtered sections can still be used. This not only wastes resources but also leads to poor filtration efficiency.

[0003] Therefore, existing air purifiers need further improvement. [Summary of the Invention]

[0004] The purpose of this invention is to provide a uniform filtration structure for air purifiers, which enables the hollow cylindrical filter element to uniformly filter air impurities, ensures consistent surface utilization, improves filtration efficiency, and saves resources.

[0005] To achieve the above objectives, the present invention adopts the following solution:

[0006] A uniform filtration structure for use in an air purifier includes a purifier body, a replaceable air filter and a filter mounting slot within the purifier body, an air guide ring that can move up and down fitted on the outer wall of the replaceable air filter, a reciprocating drive assembly that can drive the air guide ring to move up and down within the replaceable air filter, a fan drive rotation structure within the purifier body, a transmission mechanism between the fan drive rotation structure and the reciprocating drive assembly, a speed limiting structure on the purifier body for limiting the up and down movement speed of the reciprocating drive assembly, and an annular air inlet at the bottom of the purifier body, the annular air inlet communicating with the outer side of the air guide ring.

[0007] Furthermore, the purifier body includes a shell, a fan structure is provided in the middle of the shell, a filter installation slot is provided below the fan structure, an air outlet is provided above the fan structure, and a control panel is provided in the middle of the air outlet.

[0008] Furthermore, the air outlet is arranged in a ring shape;

[0009] The replaceable air filter is a hollow cylindrical design.

[0010] Furthermore, the air guide ring includes a sealing ring fitted around the outer circumference of the replaceable air filter element, and an annular vent is provided in the middle of the sealing ring, with multiple connecting rods provided inside the annular vent.

[0011] Furthermore, the reciprocating drive assembly includes a support rod disposed in the middle of the filter element mounting groove, a horizontal rotating shaft disposed at the upper end of the support rod, a swing rod disposed at one end of the horizontal rotating shaft, a central bushing disposed at the upper end of the filter element mounting groove, a telescopic shaft disposed vertically inside the central bushing, a connecting frame disposed between the telescopic shaft and the sealing ring, a first hinge seat disposed on the swing rod, a second hinge seat disposed at the lower end of the telescopic shaft, and a connecting rod hinged between the first hinge seat and the second hinge seat.

[0012] Furthermore, the fan blade driven rotation structure includes multiple rotating ring guide support rods disposed on the outer wall of the central shaft sleeve, a rotating inner ring capable of rotation is installed between the multiple rotating ring guide support rods, a rotating outer ring is disposed on the outer sleeve of the rotating inner ring, and multiple power fan blades are disposed between the rotating inner ring and the rotating outer ring.

[0013] Furthermore, the transmission mechanism includes a rotating shaft fixing sleeve disposed on one side of the central shaft sleeve, a transmission shaft disposed on the rotating shaft fixing sleeve, a driven gear disposed at the upper end of the transmission shaft, a first bevel gear disposed at the lower end, a driving gear disposed on the inner wall of the rotating outer ring, the driving gear and the driven gear meshing and transmitting power, and a second bevel gear disposed at the other end of the horizontal rotating shaft, the second bevel gear and the first bevel gear meshing and transmitting power.

[0014] Furthermore, the speed limiting structure includes a damping cylinder disposed on the purifier body, a partition plate disposed in the middle of the damping cylinder, the partition plate dividing the interior of the damping cylinder into an upper cavity and a lower cavity, a push shaft disposed vertically inside the damping cylinder, the push shaft being fixedly connected to the connecting frame, a speed limiting push plate fixedly connected to the push shaft being disposed in both the upper cavity and the lower cavity, the partition plate being provided with a through hole structure for connecting the upper cavity and the lower cavity, and the upper cavity and the lower cavity being filled with fluid material.

[0015] In summary, the advantages of this invention over the prior art are:

[0016] This invention addresses the shortcomings of existing air purifier filter structures. Through its structural design, it offers the following advantages: the air guide ring controls the airflow path, reciprocating up and down on the outer surface of the filter element, allowing air molecules to penetrate to different surface positions, resulting in more uniform filtration. Furthermore, the use of flowing air as power enables the reciprocating drive mechanism to operate automatically, driving the air guide ring to move automatically up and down. Additionally, a damping structure prevents excessive airflow speed from causing the air guide ring to exceed its maximum movement speed range, improving operational stability, enhancing air filtration quality, and saving resources.
