[0002] As a key device for improving indoor air quality, the core function of an air purifier relies on the filter element's ability to filter harmful substances such as particulate matter and gaseous pollutants in the air.

[0003] In existing technologies, filter elements mostly adopt cylindrical or plate-shaped structures. Among them, cylindrical filter elements occupy the mainstream position in the market due to their larger effective filtration area and low air resistance characteristics.

[0004] However, current cylindrical filter cartridges are usually designed as an integrated structure, making it difficult to disassemble the filter screen separately. During transportation, the filter screen needs to maintain its unfolded shape, resulting in a large transportation volume and increased transportation costs. Utility Model Content

[0005] This invention addresses the aforementioned problems in the existing technology by proposing an air purifier filter element structure that facilitates filter installation and removal.

[0006] This utility model can be achieved through the following technical solutions:

[0007] An air purifier filter element structure that facilitates filter installation and removal includes:

[0008] A support frame, comprising a support body and a base connected together;

[0009] A filter screen, which is fitted around the outer perimeter of the supporting body;

[0010] The top cover is connected to the end face of the support body away from the base via a detachable connection structure, wherein...

[0011] When the top cover is installed, the top cover and the base together form an axial constraint on the filter screen at both ends along the axial direction of the support body.

[0012] After the top cover is removed, the filter screen is detached and removed along the axial direction of the support body.

[0013] As a further improvement of this utility model, the filter screen is composed of a flexible material layer and has flexible deformation characteristics that can be folded and compressed.

[0014] As a further improvement of this utility model, it also includes a carbon mesh, which is disposed in the inner ring of the filter screen and sleeved on the support body.

[0015] As a further improvement of this utility model, the end face of the bracket away from the base is provided with a connecting end cover, and the top cover and the connecting end cover are connected by a detachable connection structure.

[0016] As a further improvement of this utility model, the connecting end cap has a positioning ring that protrudes outward along the axis of the bracket, and at least one locking protrusion is provided on the inner wall of the positioning ring.

[0032] The following are specific embodiments of the present invention, which are described in conjunction with the accompanying drawings. The technical methods of the present invention will be further described, but the present invention is not limited to these embodiments.

[0033] like Figures 1-2 As shown, this utility model provides an air purifier filter element structure that facilitates filter installation and removal, comprising:

[0034] The bracket 100 includes a connected support body 110 and a base 120, providing a robust base frame for the entire filter element;

[0035] The filter screen 200 is fitted around the support body 110 and can be removed along the axis of the support body 110 after the top cover 300 is removed. The filter screen 200 is made of flexible material and has folding and compression characteristics, which allows it to be compressed during non-use or transportation to reduce space occupation.

[0036] The top cover 300 is connected to the end face of the support body 110 away from the base 120 via a detachable connection structure. This design not only ensures the stability of the filter screen 200 during installation, but also facilitates quick installation and removal by the user. When the top cover 300 is installed, the top cover 300 and the base 120 form an axial constraint on the filter screen 200 at both ends along the axial direction of the support body 110. When the top cover 300 is removed, the filter screen 200 is detached and removed along the axial direction of the support body 110.

[0037] Compared to the integrated filter element structure in the prior art, the filter element structure provided in this embodiment greatly simplifies the installation and removal process of the filter screen 200 through the detachable connection design between the top cover 300 and the support body 110. The filter screen 200 can be disassembled and installed without the need for professional tools, which has at least the following advantages:

[0038] 1. Reduce transportation costs: By disassembling the filter screen 200 and adopting a foldable and compressible flexible filter screen 200 design, the problem of large volume caused by the need to maintain the unfolded filter screen shape during transportation of traditional filter elements is solved, effectively reducing transportation costs and storage space requirements.

[0039] 2. Enhanced flexibility of use: The easy-to-disassemble design allows users to flexibly replace different types of filters 200 according to actual needs, in order to adapt to different air purification requirements, while also helping to maintain the best performance of the equipment;

[0040] 3. Improved maintenance efficiency: The simple filter 200 removal mechanism facilitates regular maintenance by users, thereby helping to extend the overall lifespan of the air purifier and maintain its efficient operation.

[0041] Preferably, it also includes a carbon mesh 210, which is disposed in the inner ring of the filter screen 200 and fitted on the support body 110. The carbon mesh 210 not only increases the filter element's adsorption capacity for gaseous pollutants (such as odors, volatile organic compounds, etc.), but also maintains the compactness of the overall structure and high-efficiency filtration performance.

[0042] Specifically, the CarbonNet 210 can effectively adsorb gaseous pollutants in the air, such as formaldehyde, benzene and other volatile organic compounds (VOCs), as well as various odors, providing users with a cleaner and healthier air environment.

[0043] By combining the carbon mesh 210 with the filter 200, the overall efficiency and effectiveness of air purification can be significantly improved without increasing the size of the equipment, making the air purification process more comprehensive and thorough.

[0044] Furthermore, despite the addition of carbon mesh 210, the overall filter element structure remains compact and does not affect its ease of installation and removal, which ensures both ease of use and improves the product's cost-effectiveness.

[0045] Preferably, the end face of the bracket 100 away from the base 120 is provided with a connecting end cover 130, and the top cover 300 and the connecting end cover 130 are connected by a detachable connection structure to realize the quick installation and removal of the top cover 300. The following is a detailed description of the top cover 300 and the connecting end cover 130:

[0046] First, the connecting end cap 130 has a positioning ring 131 that protrudes outward along the axis of the bracket 100. The inner wall of the positioning ring 131 is provided with at least one locking protrusion 132. This design provides a precise docking position for the top cover 300.

[0047] Correspondingly, the top cover 300 has a docking ring 310 that mates with the positioning ring 131. The docking ring 310 is provided with an L-shaped locking groove 320. When the top cover 300 is connected to the connecting end cover 130, the docking ring 310 is embedded in the positioning ring 131, and the locking protrusion 132 and the locking groove 320 mate to form a rotation locking structure.

[0048] By rotating the top cover 300, the locking protrusion 132 can be engaged in the locking groove 320, thereby achieving axial constraint of the top cover 300 and ensuring that the top cover 300 is firmly fixed on the bracket 100. When the filter screen 200 needs to be removed, rotate the top cover 300 in the opposite direction and then take out the filter screen 200 along the axial direction of the support body 110.

[0049] This design greatly simplifies the installation and removal process of the top cover 300, allowing the operation to be completed without the use of tools.

[0050] The design of the positioning ring 131 and the docking ring 310 ensures that the top cover 300 can be accurately aligned with the bracket 100, reducing installation errors and improving the overall assembly quality.

[0051] The rotation locking structure formed by the locking protrusion 132 and the locking groove 320 improves the ease of disassembling the top cover 300 on the one hand, and ensures the stability of the top cover 300 after installation on the other hand, preventing it from accidentally loosening or falling off.

[0052] Preferably, the outer edge of the top cover 300 is provided with an annular retaining edge 330 that protrudes in the same direction as the docking ring 310. After the top cover 300 is connected to the positioning ring 131 on the connecting end cover 130 through its docking ring 310, this annular retaining edge 330 will cover the outer edge of the filter screen 200, thereby ensuring the stability and reliability of the filter screen 200 after installation and preventing displacement or detachment due to airflow impact or vibration during the operation of the air purifier.

[0053] Preferably, the top cover 300 is provided with a handle 340. The presence of the handle 340 makes it easier for users to apply force when installing or removing the top cover 300, saving maintenance time and improving overall usage efficiency.

[0054] Preferably, the filter 200 has an installation groove extending along its axis, and a detachable label carrier 220 is embedded in the installation groove. The label carrier 220 is equipped with a hidden anti-counterfeiting label 221, which effectively prevents the circulation of counterfeit and shoddy products, protects consumer rights and brand image, and the anti-counterfeiting label 221 has RFID label identification function. The RFID label identification function means that when it enters the range of the reader, the reader can activate the anti-counterfeiting label 221 through radio waves and exchange data with it, so as to achieve automatic identification, which has high efficiency and flexibility.

[0055] Furthermore, the design of the marking carrier 220 takes into account the precise fit with the mounting channel. Its radial cross-sectional shape forms a complementary and interlocking structure with the mounting channel. This means that even if the marking carrier 220 is added, it will not affect the overall shape or performance of the filter screen 200. This ensures that the filter screen 200 can still maintain the ideal annular cylindrical structure during use, thereby not affecting the airflow efficiency and filtration effect.

[0056] By cleverly integrating the label carrier 220 into the filter 200 structure, without increasing the additional space occupation or affecting the neatness of the appearance, a design solution that is both beautiful and practical is provided to users.
