Description

Technical Field

[0001] This utility model relates to the field of filter technology, and in particular to a novel structure of a pleated air filter. Background Technology

[0002] A pleated air filter is a high-capacity air filter suitable for both constant and variable airflow systems. Its main component for filtration is the filter element.

[0003] The prior art, authorized by CN214972603U, discloses a filter structure in a high-adsorption air filter assembly, which is assembled from a filter frame and several filter elements. However, in actual assembly, the filter elements and the filter frame need to be connected with adhesive. However, in actual operation, after the filter element is installed into the filter frame, the bottom surface of the filter element adheres to the inner wall of the filter frame, and the adhesive cannot be completely immersed, thus the adhesive cannot play its role in connecting the filter element and the filter frame. This results in a weak adhesive fixation effect after the filter element is assembled, causing the filter element to shake inside, which not only affects the filtration effect, but also makes the overall process substandard.

[0004] Therefore, a novel pleated air filter structure needs to be designed to solve the above problems. Utility Model Content

[0005] The purpose of this invention is to provide a novel structure for a pleated air filter to overcome the aforementioned shortcomings of the existing technology.

[0006] To achieve the above objectives, the present invention adopts the following technical solution: A novel structure for a pleated air filter includes a filter frame and several sets of filter elements placed within the filter frame. The filter frame is characterized by being composed of a bottom frame, side frames, and a top frame. Both the bottom and top frames have mounting grooves for accommodating the filter elements. Support blocks for supporting the filter elements are provided within the mounting grooves, and several sets of through-grooves for the flow of adhesive liquid are provided on the support blocks.

[0007] Preferably, the side frames are respectively disposed on both sides of the bottom frame and connected by a snap-fit ​​connection. A retaining pin is provided on the top side of the side frame for mounting with the top frame, and the two sides of the top frame are provided with retaining slots for mounting with retaining slots.

[0008] Preferably, a plurality of the filter elements are sandwiched between the bottom frame and the top frame and sequentially spliced ​​into a W-shaped structure in the corresponding area of ​​the filter screen frame.

[0009] Preferably, the support block can also be a mesh structure.

[0010] Preferably, a protective mesh is attached to the outer surface of the filter element.

[0011] The beneficial effects of this utility model are as follows: This technical solution provides a channel for the flow of adhesive liquid in the mounting groove of the bottom frame or top frame for installing the filter element. This ensures that the adhesive liquid can flow into the interior through the channel when assembling the filter element, avoiding the adhesive liquid being blocked by the filter element. This solves the problem of the filter element blocking the flow of adhesive liquid during assembly in the prior art, thereby allowing the adhesive liquid to fully adhere, ensuring the connection between the filter element and the frame, ensuring both sealing and stability, preventing the filter element from falling off, and ensuring the sealing effect.

Detailed Implementation

[0013] Reference Figures 1 to 5 A novel structure of a pleated air filter includes a filter frame 1 and a plurality of filter elements 2 placed within the filter frame; The filter frame 1 is composed of a bottom frame 11, a side frame 12 and a top frame 13. The side frames are respectively located on both sides of the bottom frame and are connected by a snap-fit ​​connection. A retaining pin 121 for mounting the top frame is provided on the top side of the side frame. The top frame is provided on both sides with retaining slots 131 for mounting. The assembly is completed by inserting the retaining pin of the top frame into the retaining slot and installing it on the side frames on both sides. Several filter elements are sandwiched between the bottom frame and the top frame and sequentially spliced ​​into a W-shaped structure in the corresponding area of ​​the filter screen frame. The filter element at the first end is attached to one side of the bottom frame, and the filter element at the last end is attached to the other side of the bottom frame. The V-shaped angle formed by splicing any two adjacent filter elements is ; To facilitate filter element installation, both the bottom frame 11 and the top frame 13 are provided with mounting grooves 3 for accommodating the filter element. In actual manufacturing, to ensure sealing and fixation, the filter element needs to be connected to the bottom and top frames using adhesive. To ensure the adhesive can flow and fully connect the filter element to the top and bottom frames, a support block 31 for supporting the filter element is provided in the mounting groove 3. To facilitate adhesive flow, several sets of through grooves 32 for adhesive flow are provided on the support block.

[0014] refer to Figure 6 As shown, the support block 31 can also be a mesh structure, and the through groove 32 is a mesh-like hollow groove. Its purpose is to allow the adhesive to flow into the inside, so that when the filter element is placed during installation, the adhesive cannot completely penetrate into the inside.

[0015] The outer surface of the filter element 2 is covered with a protective mesh 4 to protect the internal filter element and prevent direct human contact that could cause damage.

[0016] The advantages of this utility model are that, by setting a channel for the flow of adhesive liquid in the mounting groove of the bottom frame or top frame for installing the filter element, the adhesive liquid can flow into the interior through the channel during the assembly of the filter element, avoiding the adhesive liquid being blocked by the filter element. This allows the adhesive liquid to fully adhere, ensuring the connection between the filter element and the frame, ensuring both sealing and stability, preventing the filter element from falling off, and ensuring a sealing effect.

[0017] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
