[0036] Example 1

[0037] Reference Figure 1-6, a filter box, including a box body 1, the box body 1 is the main part of the filter box, and is made of high-quality materials that are corrosion-resistant and impact-resistant, ensuring that the filter box has sufficient strength and stability during use. The top and bottom of the box body 1 are provided with through holes, which are used to install inlet and outlet pipes 2 and inlet pipes 3 respectively. The outlet pipe 2 is located on the through hole at the top of the box body 1, and is used to discharge the air that has been filtered by activated carbon. The inlet pipe 3 is located on the through hole at the bottom of the box body 1, and is used to introduce the air that needs to be filtered. The inlet pipe 3 can be provided with a filter net to preliminarily filter out large particles of impurities in the air. There are four support columns 4, which are arranged at equal intervals at the bottom of the box body 1 to play a role of fixed support, ensuring that the filter box remains stable during use. The sealing door 5 is connected to the opening of the box body 1 by a hinge, which is convenient for opening and closing. The design of the sealing door 5 makes it more convenient to maintain the inside of the box body 1 or replace the activated carbon. The drawer 7 is a key component of the filter box, which is used to place the activated carbon. The multiple drawers 7 are arranged on the inner wall of the box body 1, which is convenient for the layered placement of the activated carbon and improves the filtering effect.

[0038] The sliding assembly is an important part for realizing the sliding of the drawer 7 in the box body 1. Specifically, the sliding assembly includes a plurality of sliders 701, which are arranged on the outer sides of the corresponding drawers 7. The inner wall of the box body 1 is fixedly connected with a plurality of U-shaped frames 101, and is provided with a plurality of U-shaped grooves 102. The U-shaped grooves 102 are slidably connected with the corresponding sliders 701. The U-shaped frames 101 are used as supports for the drawer 7, and the sliders 701 on the drawer 7 slide in the U-shaped grooves 102 in the box body 1, thereby realizing the sliding function of the drawer 7 in the box body 1. This design makes the disassembly and installation of the drawer 7 very simple, and is convenient for users to replace and maintain the activated carbon.

[0039] In order to improve the filtering effect, two filter slots 702 are provided on one side of the multiple drawers 7. The filter slots 702 are slidably connected with the filter screens 9. When the filter screens 9 need to be replaced or cleaned, the filter screens 9 only need to be taken out from the filter slots 702. The operation is simple and convenient.
