Description

Technical Field

[0001] The utility model relates to the technical field of air filter structures, in particular to an air filter structure. Background Art

[0002] An air filter is a device that removes particulate impurities from the air. When a piston machine is working, if the inhaled air contains dust and other impurities, it will aggravate the wear of the parts, so an air filter must be installed. The air filter consists of two parts: the filter element and the housing.

[0003] For example, the Chinese authorized patent with announcement number CN216149281U (an air filter element with a new type of sealing structure) includes a frame and a filter medium. The frame is a hollow rectangular structure, which encloses an air intake channel. The air intake channel includes a straight channel and a diffusion channel. The inner wall of the straight channel is straight and has no steps. The axial cross-section of the diffusion channel is trapezoidal, and its inner wall is straight and has no steps. The connection between the straight channel and the diffusion channel has a smooth transition. The four sides of the frame are the left and right sides perpendicular to the horizontal plane and the upper and lower sides parallel to the horizontal plane. The filter medium includes filter paper, which is pleated and is formed by connecting multiple V-shaped units in sequence. Slots are respectively provided on the left and right sides of the frame. The outer edges of the V-shaped units at both ends of the filter paper are provided in the slots. The inner walls opposite to the upper and lower sides are respectively provided with V-shaped grooves that are adapted to the cross-section of the V-shaped units. The top and bottom of the filter paper are provided in the V-shaped grooves.

[0004] However, the air filter structure in the above-mentioned prior art has poor stability during installation, and is prone to shaking during use, which affects its filtering quality; therefore, it does not meet existing needs. In this regard, we propose an air filter structure. Utility Model Content

[0005] The purpose of the utility model is to provide an air filter structure to solve the problem that the air filter structure in the prior art proposed in the above background art has poor stability during installation, and is prone to shaking during use, which affects its filtering quality.

[0006] To achieve the above-mentioned purpose, the utility model provides the following technical solutions: an air filter structure, including a support seat, a filter element and a rainproof cap, a filter element is arranged above the support seat, a bottom cover is arranged at the bottom of the filter element, a top cover is arranged on the top of the filter element, an installation port is arranged inside the top cover, a rainproof cap is arranged on the installation port, plug-in slots are arranged on both sides of the bottom of the support seat, a movable frame is installed inside the plug-in slot, and the movable frame is plug-in connected to the inside of the plug-in slot.

[0007] Preferably, the plug-in slots and the movable racks are each provided with two groups, and fixing screws are installed on the lower surface of the movable rack.

[0008] Preferably, a threaded rod is installed on one end surface of the movable frame, the threaded rod is threadedly connected to the interior of the movable frame, and the threaded rod is arranged to penetrate the interior of the movable frame.

[0009] Preferably, a turning handle is provided on one side of the threaded rod, and a fastening pad is installed on the end surface of the other side of the threaded rod.

[0010] Preferably, an air intake net is installed inside the rain cap, and the air intake net is plug-connected to the inside of the rain cap.

[0011] Preferably, a retaining ring is provided below the rainproof cap, a cap seat is provided below the retaining ring, a clamp is installed on the cap seat, and a fastening screw is installed on one side of the clamp.

[0012] Compared with the prior art, the beneficial effects of the present invention are:

[0013] The utility model provides a support seat at the bottom of the bottom cover, and a limit column is provided on the upper surface of the support seat to be plugged into the inside of the filter element. Then, the support seat is placed inside the shell, and the movable frame is moved inside the plug-in slot so that the movable frame is unfolded to both sides and fixed with fixing screws. Then, the threaded rod is rotated to connect the fastening pad to the inner wall of the filter element shell to play a supporting and fixing role, thereby ensuring its stability during use. This solves the problem that the air filter structure in the prior art has poor stability during installation, which makes it easy to shake during use, affecting its filtration quality.

[0014] By setting up a rain cap, you can prevent rainwater from entering the air filter, thereby protecting the filter element from moisture and corrosion and extending its service life. In the rainy season or humid environment, the rain cap can effectively prevent rainwater from directly wetting the filter element, reducing the performance degradation or damage of the filter element caused by moisture. At the same time, it prevents impurities from entering and keeps the filter element clean. BRIEF DESCRIPTION OF THE DRAWINGS
