Description

Technical Field

[0001] This utility model relates to the field of air purification technology, specifically to an activated carbon filter structure for air purification. Background Technology

[0002] Activated carbon filters are primarily used to adsorb odors, harmful gases, and some particulate pollutants from the air. Through physical adsorption, they utilize the highly porous structure and large specific surface area of ​​activated carbon to effectively remove harmful gases such as formaldehyde, benzene, and TVOCs (total volatile organic compounds), as well as smoke and other odors. Furthermore, activated carbon filters can also adsorb low-concentration pollutants from the air. They are highly efficient, safe, and inexpensive. Employing physical adsorption principles, they require no added chemicals and pose no secondary pollution or health risks to humans. Due to their superior adsorption performance, activated carbon filters are widely used in various air purifiers.

[0003] A search revealed Chinese utility model patent CN211041232U, which describes an activated carbon filter structure for air purification. This structure comprises a hollow cuboid composed of a frame and a mesh panel. Filter material is installed within the cavity of the cuboid structure to form the filter. The frame is formed by bending a square tube, making the material readily available. Furthermore, it utilizes existing laser cutting technology, eliminating the need for extensive welding and bending processes, resulting in a simple, cost-effective, and aesthetically pleasing design. The openings on the square tube are designed as a V-shaped opening on the inner side of the frame and an isosceles triangular opening between the V-shaped opening and the outer side of the frame. The two sides of the isosceles triangular opening are arc-shaped, with the arcs concave into the structure of the isosceles triangular opening. This structure ensures that after bending, the uncut portion of the square tube fits perfectly against the arc-shaped sides, creating a smooth transition at the bend. The internal frame remains rectangular, resulting in an aesthetically pleasing appearance.

[0004] The existing devices have the following problems when in use: when filtering air, the activated carbon filter area is small and the filtration efficiency is poor. However, increasing the filtration area of ​​the activated carbon filter requires increasing the installation space of the activated carbon filter, making the purification equipment bulky. Secondly, the operation of replacing and maintaining the activated carbon filter is complicated, making disassembly and assembly inconvenient and the practicality low. Utility Model Content

[0005] The purpose of this invention is to provide an activated carbon filter structure for air purification to solve the problems mentioned in the background art.

[0006] To achieve the above objectives, this utility model provides the following technical solution: an air purification activated carbon filter structure, including a mounting frame, a slot, a connecting plate, and an activated carbon filter. The mounting frame has a slot on one side, and a connecting plate is disposed inside the slot. An activated carbon filter is disposed on one side of the connecting plate. A connecting seat is disposed on one side of the mounting frame, and a guide rod is connected to one side of the connecting seat. One end of the guide rod extends into the inner groove and is connected to a limiting block. The limiting block is fitted with the connecting plate. Mounting holes are provided on both the upper and lower sides of the mounting frame.

[0007] By adopting the above technical solution, the activated carbon filter is installed in the working position through the mounting holes on the mounting bracket. The activated carbon filter is designed as a hollow trapezoid, allowing air to be filtered through all five sides, thus increasing the filtration area. Furthermore, the activated carbon filter has three sets, improving airflow efficiency and saving space. Pulling the pull ring moves the connecting seat, which in turn causes the limiting block at one end of the guide rod to disengage from the limiting groove. This allows the activated carbon filter to be removed from the mounting bracket, facilitating maintenance and replacement, and improving its performance.

[0008] Preferably, the activated carbon filter consists of a frame and an activated carbon filter core, wherein the frame is made of aluminum and the interior of the frame is filled with the activated carbon filter core.

[0009] By adopting the above technical solution, activated carbon filter elements can filter dust and harmful substances in the air, thereby improving the air purification effect.

[0010] Preferably, a pull ring is rotatably connected to the side of the connecting seat away from the guide rod.

[0011] By adopting the above technical solution, the pull ring can be folded after rotation, reducing the space occupied.

[0012] Preferably, the mounting bracket has an inner groove, a spring is fixedly connected to one side of the inner groove, and a limit block is fixedly connected to one end of the spring.

[0013] By adopting the above technical solution, when the pull ring is pulled, the limiting block compresses the spring and retracts into the inner groove, thereby disengaging the limiting block from the limiting groove. During installation, the activated carbon filter screen is aligned with the slot and the connecting slot and pushed in. When the pull ring is released, the limiting block enters the inner groove under the action of the spring, thereby fixing the activated carbon filter screen. The operation is simple and improves the convenience of installation and disassembly.

[0014] Preferably, a limiting groove is provided on one side of the connecting plate, and the limiting block is adapted to the limiting groove.

[0015] By adopting the above technical solution, the activated carbon filter screen can be fixed through the cooperation of the limiting block and the limiting groove.

[0016] Preferably, a connecting groove is provided on one side of the interior of the mounting bracket, and the connecting groove is adapted to the connecting plate.

[0017] By adopting the above technical solution, the connecting plate enters the interior of the connecting groove to fix one end of the activated carbon filter, improving the ease of installation.

[0018] Preferably, the cross-section of the activated carbon filter is a hollow trapezoid, and the mounting frame is made of stainless steel.

[0019] By adopting the above technical solution, the stainless steel mounting rack can remain dry for a long time and avoid rusting.

[0020] Compared with the prior art, the beneficial effects of this utility model are:

[0021] 1. The activated carbon filter is designed as a hollow trapezoid, allowing air to pass through all five sides of the filter, thus increasing the filtration area. Furthermore, the filter has three sets of filters, improving airflow efficiency and saving space.

[0022] 2. Pulling the pull ring moves the connecting seat, which in turn moves the limiting block at one end of the guide rod away from the limiting groove. This allows the activated carbon filter to be removed from the inside of the mounting frame, facilitating maintenance and replacement of the activated carbon filter, improving its performance, and increasing the ease of installation and disassembly.

A connecting groove 5 is opened on one side of the interior of the mounting frame 1. The connecting groove 5 is adapted to the connecting plate 4. Pulling the pull ring 6 drives the connecting seat 7 to move. The connecting seat 7 then drives the limiting block 12 at one end of the guide rod 13 to disengage from the limiting groove 9. Thus, the activated carbon filter screen 2 can be pulled to remove the activated carbon filter screen 2 from the interior of the mounting frame 1, which facilitates the maintenance and replacement of the activated carbon filter screen 2 and improves the performance of the activated carbon filter screen 2. During installation, the activated carbon filter screen 2 is aligned with the slot 8 and the connecting groove 5 and pushed in.
