[0024] Clearly, the described embodiments are merely a part of the embodiments of the present application, rather than all the embodiments.

[0025] Embodiment one:

[0026] In combination Figures 1-2 The air purifier filter element shown in the figure, including filter element main body 1, filter element main body 1 overall regular rectangular flat plate structure, filter element main body 1 upper surface evenly distributed with several hollow slot 2, these hollow slot 2 array type arrangement, facilitate subsequent air flow, located in each group of hollow slot 2 below are provided with "V" shaped fixing piece 3, fixing piece 3 both sides wall are provided with placing groove 4, placing groove 4 along the length direction of fixing piece 3 side wall extension, placing groove 4 inner surface through the anti-skid treatment, placing groove 4 both ends are provided with buckle groove 5, placing groove 4 are provided with filter element assembly 6, filter element main body 1 outer wall around is provided with first sealing strip 7, first sealing strip 7 also adopt silica gel material, its shape and the appearance of filter element main body 1 match, can be in filter element subsequent installation to the inside of air purifier, with the installation part of air purifier closely, form sealed structure;

[0027] The filter core assembly 6 is the core component for realizing the air purification function, and comprises a filter core frame 601 which has the advantages of light weight and high strength. An inner side wall of the filter core frame 601 is provided with a paper core 602. The paper core 602 can provide the maximum filtering area in a limited space. The surface of the paper core 602 is subjected to electrostatic poling treatment, so that the paper core 602 has stronger adsorption capacity and can effectively intercept small particulate matters, harmful gases and odors and other pollutants in the air. A plurality of connecting rods 603 are arranged on the paper core 602. The connecting rods are firmly adhered to the paper core 602 by means of a high-temperature-resistant and high-strength adhesive, so as to effectively support the paper core 602 and prevent the paper core 602 from deforming after being softened due to moisture. A pressing strip 604 is arranged above the connecting rods 603. The pressing strip 604 can further limit the connecting rods 603 and further enhance the stability of the paper core 602. Meanwhile, when the air purifier is working, the pressing strip 604 can effectively reduce the vibration and abnormal sound of the paper core 602 caused by airflow impact. A second sealing strip 605 is arranged around the outer wall of the filter core frame 601. The second sealing strip 605 is also made of silica gel. The second sealing strip 605 cooperates with the placement groove 4. When the filter core assembly 6 is installed in the placement groove 4, the second sealing strip 605 can be tightly attached to the inner wall of the placement groove 4 to form an effective sealing structure, so as to prevent unfiltered air from leaking through the gap between the filter core assembly 6 and the placement groove 4. Elastic sheets 606 are arranged on the side walls at both ends of the filter core frame 601. The elastic sheets 606 are adapted to the buckle grooves 5. When the filter core assembly 6 is installed in the placement groove 4, the elastic sheets 606 will be elastically deformed to abut against the buckle grooves 5, so as to realize the quick installation and reliable fixation of the filter core assembly 6.

[0028] In the embodiment, the hollow grooves 2 are arranged in a rectangular array on the upper surface of the filter core body 1 to reduce the turbulence phenomenon of the airflow. The spacing between the two adjacent groups of hollow grooves 2 is accurately set to 15-20 mm, so as to avoid the insufficient rigidity of the whole due to the excessively large hollow area and maximize the air flow efficiency.

[0029] In the embodiment, the fixing member 3 and the filter core body 1 are integrally formed to ensure the stability and reliability of the whole structure. The included angle of the “V”-shaped fixing member 3 is set to 10°-60°. The included angle range effectively disperses the airflow pressure generated during the operation of the air purifier and reserves reasonable space for the installation of the filter core assembly 6. Meanwhile, the flow guide channel formed by the “V”-shaped structure can guide the airflow to uniformly pass through the filter core assembly 6, thereby improving the air purification efficiency. Moreover, the included angle in the range can also reduce the swing of the paper core 602 when it is wet.

[0030] The paper core 602 in the embodiment adopts a folded structure, so that the paper core 602 presents a regular wave shape in an unfolded state. This structure design effectively increases the surface area of the paper core 602 and improves the adsorption capacity of pollutants in the air. The folding of the paper core 602 is set to 3-5 folds per centimeter. This folding density range can ensure that the paper core 602 has sufficient filtration area to efficiently intercept pollutants such as fine particulate matter and harmful gases, and can also ensure that the paper core 602 has good air permeability after folding, avoiding excessive air flow resistance due to excessive folding density, which affects the overall operating efficiency of the air purifier.

[0031] In the embodiment, the connecting rods 603 are arranged in an equidistant matrix on the surface of the paper core 602. The spacing between adjacent connecting rods 603 is controlled within the range of 20-30 mm. This spacing can provide uniform and stable support for the paper core 602, and also avoids excessive material costs and air flow resistance due to excessive spacing. The diameter of the connecting rod 603 is set to 2-3 mm, which ensures the rigidity and toughness of the connecting rod 603 while minimizing the obstruction to air flow.

[0032] In the embodiment, the elastic sheet 606 is made of spring steel. This spring steel has excellent elastic limit, fatigue strength, and impact resistance, and can maintain good elasticity and structural stability during long-term and frequent elastic deformation, without being prone to plastic deformation or rupture. The elastic sheet 606 is controlled within the range of 0.8-1.2 mm. The cross-section of the elastic sheet 606 is in the shape of a circular arc. The circular arc shape allows the elastic sheet 606 to smoothly deform elastically when inserted into the buckle slot 5, reducing the insertion resistance and facilitating the installation of the filter core assembly 6 by the user.
