Air purifier with uniform air guiding structure

Abstract

This invention discloses an air purifier with a uniform airflow structure, comprising a purifier body, an annular air filter layer disposed within the purifier body, and air inlets disposed around the purifier body. Four movable baffle mechanisms for closing the annular air filter layer are evenly distributed on the outer circumference of the annular air filter layer. A control switching structure is disposed within the purifier body to control the synchronous movement of two oppositely arranged movable baffle mechanisms. By alternately closing different angle positions of the annular filter element, the airflow path is changed, making the filtration volume of each surface of the annular filter element more uniform and improving the overall utilization rate of the annular filter element. Simultaneously, arc-shaped baffles are movably disposed on the inner and outer walls of the annular filter element at corresponding angles to close the corresponding angle positions of the annular filter element. Multiple arc-shaped baffles alternately close different angles of the filter element, achieving more uniform filtration and improving the utilization rate of the annular filter element.

Description

[Technical Field] This invention relates to air purifiers, and more particularly to an air purifier with a uniform airflow structure. [Background Technology] Air purifiers are used to purify impurities in the air and improve air purity. They typically have an internal ring filter to filter dust and other impurities. Air enters from the outer wall of the ring filter and flows out from the top center of the ring filter. However, because the air inlet is located on one side of the ring filter, a large amount of dust will accumulate on the windward side of the ring filter over time, causing blockage. The non-windward side has a low filtration capacity, resulting in uneven filtration across the entire filter.

[0001] Therefore, existing air purifiers need further improvement. [Summary of the Invention] The purpose of this invention is to provide an air purifier with a uniform airflow structure, which can change the airflow path, making the filtration more uniform on each side of the filter element and the utilization rate more average.

[0002] To achieve the above objectives, the present invention adopts the following solution: An air purifier with a uniform air guiding structure includes a purifier body, an annular air filter layer disposed inside the purifier body, an air inlet disposed around the purifier body, four movable baffle mechanisms for closing the annular air filter layer evenly distributed on the outer circumference of the annular air filter layer, and a control switching structure disposed inside the purifier body for controlling two oppositely disposed movable baffle mechanisms to achieve synchronous movement. The four movable baffle mechanisms are arranged in pairs facing each other, forming two groups; The control switching structure can control the two sets of movable baffle mechanisms to open or close alternately.

[0003] Furthermore, the purifier body includes a purifier, an air outlet is provided on the purifier, the air outlet is annular and located at the upper end of the purifier, a control panel is provided in the middle of the air outlet, a fan structure connected to the air outlet is provided inside the purifier, an annular air filter layer is provided below the fan structure, the fan structure is connected to the inner wall of the annular air filter layer, and the outer wall of the annular air filter layer is connected to the air inlet.

[0004] Furthermore, the movable baffle mechanism includes an inner guide groove and an outer guide groove disposed on the purifier. The inner guide groove is disposed on the inner side of the annular air filter layer, and the outer guide groove is disposed on the outer side of the annular air filter layer. A first slider is movably disposed on the inner guide groove, and a second slider is movably disposed on the outer guide groove. An inner arc-shaped baffle is disposed on the first slider, and an outer arc-shaped baffle is disposed on the second slider.

[0005] Furthermore, when the inner arc-shaped baffle and the outer arc-shaped baffle in the same direction are pressed against the inner and outer walls of the annular air filter layer, the filter layer at the corresponding angular position of the annular air filter layer is in a closed state; conversely, the filter layer at the corresponding angular position of the annular air filter layer is in a flow state.

[0006] Furthermore, the control switching structure includes a rotating circular plate mechanism disposed at the bottom of the purifier. The rotating circular plate mechanism is provided with an inner driving groove and an outer driving groove. A first driving shaft is disposed at the bottom of the first slider, and a second driving shaft is disposed at the bottom of the second slider. Multiple first driving shafts are movably inserted into the inner driving groove, and multiple second driving shafts are movably inserted into the outer driving groove.

[0007] Furthermore, the rotating circular plate mechanism includes a servo motor, and the output end of the servo motor is provided with a control circular plate.

[0008] Furthermore, the inner drive ring groove is convex to the left and right, and the outer drive ring groove is convex to the front and rear.

[0009] Furthermore, an inner fixed baffle is provided between two adjacent inner arc-shaped baffles, and an outer fixed baffle is provided between two adjacent outer arc-shaped baffles.

[0010] In summary, the advantages of this invention over the prior art are: This invention addresses the shortcomings of existing air purifiers. Through its structural design, it offers the following advantages: by alternately closing different angles of the annular filter element, the airflow path is altered, resulting in more uniform filtration across each surface of the annular filter element and improving its overall utilization rate. Simultaneously, arc-shaped baffles are movably installed on the inner and outer walls of the annular filter element at corresponding angles to close these angles. Multiple arc-shaped baffles alternately close different angles of the filter element, achieving more uniform filtration and further enhancing the utilization rate of the annular filter element.

When the fan structure 103 is activated, it draws outside air into the annular air filter layer 104. The air passes through the outer wall of the annular air filter layer 104 and enters the inner wall to complete the filtration work. Then, it enters the fan structure 103 from the hollow position of the annular air filter layer 104. The fan structure 103 discharges the filtered air from the air outlet 2. The movable baffle mechanism 4 of the present invention includes an inner guide groove 401 and an outer guide groove 402 disposed on the purifier 101.

An inner arc-shaped baffle 405 is disposed on the first slider 403, and an outer arc-shaped baffle 406 is disposed on the second slider 404.

[0014] When the inner arc-shaped baffle 405 and the outer arc-shaped baffle 406 in the same direction are pressed against the inner and outer walls of the annular air filter layer 104, the filter layer at the corresponding angular position of the annular air filter layer 104 is in a closed state; conversely, the filter layer at the corresponding angular position of the annular air filter layer 104 is in a flow state.
