The filter element body 63 is the core component for realizing the air purification function. It contains a variety of filter materials and structures, which can effectively filter and purify various pollutants in the air. The presence of the connecting component 4 ensures the stable installation of the filter element body 63 in the porous filter element main body shell 1, preventing the filter element body 63 from shaking or shifting during use, thereby affecting the air purification effect. The design of the linkage component 6 is to improve the convenience of filter element replacement. When the filter element body 63 needs to be replaced, the filter element body 63 can be easily removed from the porous filter element main body shell 1 by operating the linkage component 6, reducing the time and effort required for replacing the filter element. refer to Figure 3-Figure 7, control component 7, the control component 7 is located at the bottom of the linkage component 6 and is used to control the filter element body 63, and the control component 7 includes a filter ring 61 installed inside the sleeve component 5, and a cleaning ring 62 is fixedly installed on the outer wall of the filter ring 61. The bottom of the filter ring 61 is connected to the filter element body 63, and a bottom plate 65 is installed at the bottom of the filter element body 63. A card seat 75 is fixedly installed at the bottom of the bottom plate 65. A plug-in component 8 is provided at the bottom of the filter element body 63, and a positioning component for positioning the card seat 75 is provided at the top of the plug-in component 8.

The opening slot is connected to the receiving slot. The return spring 78 plays an important role in the movement of the plug plate 77. When the plug plate 77 needs to be inserted, the return spring 78 is compressed by operating the control plate 79 so that the plug plate 77 can be smoothly inserted into the limit slot. When the plug plate 77 needs to be pulled out, the elastic force of the return spring 78 can make the plug plate 77 automatically return to the receiving slot. The opening slot provides space for the movement of the control plate 79, which is convenient for the operator to control the plug plate 77. Furthermore, a sleeve assembly 5 is provided on the outer wall of the filter element body 63. The sleeve assembly 5 includes a filter seat 51 mounted on the outer wall of the filter element body 63.

A plurality of limit blocks 83 matching the filter seat 51 are also fixedly mounted on the top of the connecting bottom cover 81. The plurality of limit blocks 83 are all disposed between the curved plates 82 and the connecting seat 84. The flange base 3 provides a stable mounting foundation for the entire air purification filter element. The connection between the connecting bottom cover 81, the connecting seat 84, and the control seat 71 ensures the continuity of the air flow path and control. The circumferential distribution of the arc-shaped plate 82 and its corresponding relationship with the connecting hole 52 can guide air to enter the connecting hole 52 more evenly, thereby improving the air purification effect. The limit block 83 can limit the filter seat 51 to prevent the filter seat 51 from deflecting or shaking during use.

Furthermore, the connecting assembly 4 includes an externally threaded connecting ring 45 fixedly mounted on the bottom of the top cover 2, the outer wall of the externally threaded connecting ring 45 is screwed with an internally threaded connecting ring 42, the outer wall of the internally threaded connecting ring 42 is fixedly mounted with a flange seat 41, the bottom of the flange seat 41 is fixedly mounted with a support seat 44, the bottom of the support seat 44 is connected to the filter seat 51, and a filter cavity for the filter element body 63 to be placed is opened between the support seat 44 and the filter seat 51, and a control ring 43 is fixedly mounted on the outer wall of the bottom of the flange seat 41. The screw connection between the externally threaded connecting ring 45 and the internally threaded connecting ring 42 can achieve a close connection between the top cover 2 and other components, and also facilitate the disassembly and replacement of the filter element body 63. The flange seat 41 and the support seat 44 provide a stable support and installation space for the filter element body 63, and the filter cavity provides a working area for air purification. The control ring 43 can facilitate the operator to operate and control the connecting assembly 4; Furthermore, the linkage assembly 6 includes an expansion seat 64 connected between the filter ring 61 and the filter element body 63. A ventilation cavity connected to the filter cavity is provided inside the expansion seat 64. A storage cover 66 that matches the interior of the filter element body 63 is fixedly installed on the top of the bottom plate 65. The expansion seat 64 can expand or contract under certain conditions, thereby assisting the installation and removal of the filter element body 63. The ventilation cavity can ensure smooth circulation of air between the filter ring 61, the filter element body 63 and the filter cavity, and the storage cover 66 can protect the interior of the filter element body 63 to prevent dust and debris from entering the interior of the filter element body 63. The overall working principle of the present invention is: The plug-in assembly 8 at the bottom of the filter element body 63 is aligned with the mounting groove of the flange base 3, and the position is automatically corrected by the curvature of the arc plate 82. The support column 73 is inserted into the jack hole of the receiving column 74 to ensure that the filter element is coaxial with the axis of the housing. When the filter element is pressed down, the inclined surface of the card seat 75 contacts the plug plate 77, compressing the reset spring 78 to contract until the plug plate 77 slides into the limit groove of the support plate 76. The reset spring 78 releases the elastic force to push the plug plate 77 to clamp the limit groove, completing the rigid locking. The expansion seat 64 is compressed by the weight of the filter element, and its memory alloy material expands radially at room temperature, forming an interference fit with the inner wall of the storage cover 66. The gradient aperture design of the connecting hole 52 allows the airflow to pass through the filter element body 63 evenly, avoiding excessive local flow rate from penetrating the filter material. Polluted air enters from the honeycomb hole of the porous filter core main body shell 1, large particles are intercepted on the surface of the filter ring 61, the airflow passes through the PTFE coating layer of the cleaning ring 62, PM2.5 and other particles are adsorbed, The filter core body 63 is internally provided with an activated carbon layer, which can decompose gaseous pollutants such as formaldehyde, the arc-shaped plate 82 guides the purified air to the air outlet connected to the bottom cover 81, the limiting block 83 eliminates vortex, greatly reduces wind resistance, pressing the control plate 79 produces displacement, the plug-in plate 77 is driven to separate from the limiting groove through the lever ratio 2:1 of the bearing column 74, the energy storage of the return spring 78 is used to make the plug-in plate 77 can be inserted with the limiting groove, in addition, when the equipment operating temperature rises, the expansion seat 64 further expands, offsets the gap caused by material thermal deformation, the asymmetric structure of the gap ensures that the filter core can only be installed in a unique direction, the cleaning ring 62 produces micro-vibration under the impact of airflow, peels off the attached particles, prolongs the service life of the filter core, pulls the top cover 2, the outer threaded connection ring 45 is rotated 90° along the inner threaded connection ring 42 and then separated, so as to realize replacement; the present application is significantly superior to the traditional filter core in convenience, sealing, economy and service life, and is suitable for various high-frequency replacement scenes, and provides a hardware basis for the intelligent air purification system.
