However, the present invention may also be implemented in other ways different from those described herein. Those skilled in the art can make similar extensions without departing from the spirit of the present invention. Therefore, the present invention is not limited to the specific embodiments disclosed below.

[0027] Secondly, the term "an embodiment" or "embodiment" as used herein refers to a specific feature, structure, or characteristic that may be included in at least one implementation of the present invention. The phrase "in one embodiment" appearing in different places in this specification does not necessarily refer to the same embodiment, nor is it a single or selective embodiment that excludes other embodiments.

[0028] Example 1

[0029] Reference Figures 1-4 This is the first embodiment of the present invention. This embodiment provides a filter frame for a low-resistance high-efficiency filter, including: a carrier box 1, wherein the carrier box 1 is provided with an opening and closing component for quick opening or closing;

[0030] The carrier box 1 is equipped with a filter assembly for filtering air containing impurities;

[0031] The carrier box 1 has a cavity, and the filter assembly can be detachably installed in the cavity of the carrier box 1 by means of bolts and nuts.

[0032] The opening and closing assembly includes a slide rail 4 located on one side of the carrier box 1. A through hole is provided on the side of the carrier box 1 where the slide rail 4 is located. Mounting doors 2 are symmetrically slidably mounted on the slide rail 4, and each mounting door 2 is provided with a handle 3.

[0033] The mounting door 2 is also equipped with an adjustment component that allows the two mounting doors 2 to quickly move closer together to close or move further apart to open.

[0034] In this design, a slide rail 4 is installed on one side of the carrier box 1. The mounting door 2 slides symmetrically on the slide rail 4 via a slider. This design utilizes the principle of sliding friction to enable the mounting door 2 to move stably in a straight line. In the adjustment assembly, the mounting door 5 and mounting bracket 7 at the top of the mounting door 2 are L-shaped and do not interfere with each other. Mounting door 5 and mounting bracket 7 are respectively equipped with toothed plates 6 and 8, which mesh with gears 9. When the operator holds the handle 3 on the mounting door 2 and pushes or pulls it, gear 9, as a transmission component, converts the rotational motion into linear motion based on the gear meshing principle, enabling the two mounting doors 2 to move closer or further apart synchronously, ensuring smooth and efficient opening and closing.

[0035] The adjustment assembly includes a mounting door 5 located at the top of one mounting door 2 and a mounting bracket 7 located at the top of the other mounting door 2. Both the mounting door 5 and the mounting bracket 7 are L-shaped and do not interfere with each other. The mounting door 5 and the mounting bracket 7 are respectively provided with two toothed plates 6 and 8 facing opposite directions. Gears 9 are meshed between the toothed plates 6 and 8.

[0036] The filter assembly includes a filter box 10 installed inside the carrier box 1. Both sides of the filter box 10 are provided with through slots, and multiple filter elements 11 are vertically installed on both through slots.

[0037] The filter element 11 includes a first filter layer 12 and a second filter layer 13. The first filter layer 12 is detachably installed on the second filter layer 13, and a gap is left between the first filter layer 12 and the second filter layer 13.

[0038] The second filter layer 13 has an arc-shaped structure, and the first filter layer 12 has an M-shaped structure.

[0039] The filter box 10 is detachably installed in the cavity of the carrier box 1 using bolts and nuts, employing a threaded connection principle for easy installation and disassembly. The first filter layer 12 of the filter element 11 is detachably installed on the second filter layer 13, possibly using mechanical connections such as snap-fits or slots, to achieve relative fixation and easy separation, facilitating subsequent maintenance and replacement. Simultaneously, the filter element 11 is vertically installed on the through slots on both sides of the filter box 10, using welding, riveting, or other methods to ensure a secure installation and guarantee the stability of the filter element 11 during operation.

[0040] In summary, when it is necessary to open the carrier box 1, the operator holds the handle 3 on the mounting door 2 and pushes or pulls the mounting door 2. At this time, the mounting door 2 slides along the slide rail 4, causing the toothed plates 6 and 8 on the mounting door 5 and mounting bracket 7 to move. The linear motion of the toothed plates drives the gear 9 to rotate, which in turn causes the other toothed plate meshing with it to move in the opposite direction, so that the two mounting doors 2 move away from each other, quickly opening the carrier box 1. When closing, the handle 3 is operated in the opposite direction to bring the two mounting doors 2 closer together until they are closed.

[0041] Air containing impurities enters the filter box 10 inside the carrier box 1. Since multiple filter elements 11 are vertically installed in the through-slots on both sides of the filter box 10, when air passes through the filter elements 11, it first contacts the first filter layer 12. The M-shaped structure of the first filter layer 12 increases the contact area between the air and the filter layer, initially filtering larger particles of impurities. Next, the air passes through the gap between the first filter layer 12 and the second filter layer 13, entering the second filter layer 13. The arc-shaped structure of the second filter layer 13 further guides the airflow, finely filtering the remaining smaller particles of impurities. The two filter layers work together, and the gap in between helps improve airflow efficiency and reduce air resistance, achieving low-resistance, high-efficiency air filtration. When the filter assembly needs maintenance or replacement, the mounting door 2 is opened, and the filter box 10 is removed from the carrier box 1 by removing the bolts and nuts, allowing for individual maintenance or replacement of the filter elements 11.

[0042] It should be noted that the above embodiments are only used to illustrate the technical solution of this utility model and are not intended to limit it. Although this utility model has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can be made to the technical solution of this utility model without departing from the spirit and scope of the technical solution of this utility model, and all such modifications or substitutions should be covered within the scope of the claims of this utility model.
