[0030] Please see Figure 1 , Figure 2 and Figure 3 The filter element 100 in this embodiment is a high-efficiency filtration component designed specifically for air purification devices. It is characterized by including a mounting component 110, a filter assembly 120, a protective cover assembly 130, and a support assembly 140, with each component precisely coordinated to achieve the function of highly efficient air filtration.

[0031] In one specific embodiment, the mounting assembly 110 is the external frame of the filter element 100, mainly composed of a top cover 111 and a bottom cover 112. The top cover 111 is located at the top of the filter element 100 and has a cleverly designed snap-fit ​​structure. This structure can be firmly locked into the air purification device, ensuring the stability and reliability of the filter element 100 after installation. The bottom cover 112 is located at the bottom of the filter element 100 and together with the top cover 111, it provides solid support for the filter element 100. One end of the mounting assembly 110 (i.e., the lower end of the filter element 100) is designed as a beveled edge with a certain angle towards the central axis of the filter element, and the overall structure is hollow. This design is not only aesthetically pleasing, but more importantly, it facilitates air circulation and improves the working efficiency of the filter element 100. At the same time, the beveled edge design also makes the filter element 100 easier to install and remove.

[0032] In one specific embodiment, the filter assembly 120 consists of three layers: a first filter 121, a second filter 122, and a third filter 123. This ensures that air is adequately filtered when passing through the filter element 100. The first filter 121, as a pre-filter, is mainly responsible for blocking larger impurities such as dust and hair, preventing them from entering the filter element and affecting the filtration effect. Figure 4 As shown, the second filter 122 is a HEPA (High-Efficiency Particulate Air) filter, which is designed for particles with a diameter of 0.3 micrometers (1 / 200th the diameter of a human hair). The HEPA filter must achieve an interception efficiency of over 99.97%. Its filtration precision is extremely high, and it can effectively remove tiny particles in the air, such as PM2.5, bacteria, and viruses, providing users with cleaner air. The third filter 123 is an activated carbon filter, whose powerful adsorption capacity can remove harmful gases and odors from the air, further improving air quality. One end of the filter assembly 120 is also designed with a bevel, which perfectly matches the bevel of the mounting assembly 110. This not only enhances the overall aesthetics of the filter element 100 but also ensures a tight fit between the components.

[0033] The protective cover assembly 130 is mainly used to protect the components of the filter element 100 from damage. It consists of two parts: a first protective cover 131 and a second protective cover 132. The first protective cover 131 tightly wraps around the outside of the top cover 111, while the second protective cover 132 wraps around the outside of the filter screen assembly 120, playing an important protective role. The protective cover assembly 130 is made of plastic material with mesh. These meshes ensure air circulation while effectively preventing external objects from directly contacting the filter screen assembly 120, thereby extending the service life of the filter element 100. One end of the protective cover assembly 130 is also designed with a bevel, which echoes the bevels of the filter screen assembly 120 and the mounting assembly 110, making the overall shape of the filter element 100 more harmonious and beautiful.

[0034] The support assembly 140 includes two parts: a first support 141 and a second support 142. The first support 141 is located between the top cover 111 and the filter assembly 120, and plays a role in supporting and fixing the filter assembly 120, ensuring the stability of the filter assembly 120 during operation. The second support 142 is located between the bottom cover 112 and the filter assembly 120, and also plays a supporting role. One end of the support assembly 140 is also cleverly designed with a bevel, which matches the bevel of the filter assembly 120, the cover assembly 130 and the mounting assembly 110. This design not only enhances the overall stability of the filter element 100, but also improves its aesthetics.

[0035] Furthermore, the lower two sides of the filter element 100 are inclined at a certain angle towards the central axis of the filter element. This design makes the filter element 100 more flexible and convenient to install, and can easily adapt to the internal structure of different models of air purifiers. The upper two sides of the filter element 100 are away from the central axis of the filter element. This design provides sufficient space for the exhaust assembly, ensuring that air can be smoothly drawn into the filter element 100 for filtration. The inclination angle of the inclined sides has been carefully calculated and is preferably 30°-60°. This design not only ensures the aesthetics of the filter element 100, but also ensures smooth airflow, thereby improving the working efficiency of the filter element 100. The maximum outer diameters of the filter assembly 120, the protective cover assembly 130, and the bracket assembly 140 are matched, and their central axes are the same as the central axis of the filter element 100, symmetrical about the central axis. This precise design makes the filter element 100 more stable and reliable during installation and use, and also enhances its overall aesthetics.

[0036] like Figure 5 As shown, in one specific embodiment, the filter element 100 has a unique external frame design, presenting a simple yet stylish visual effect. This not only enhances the aesthetics of the filter element 100 but also provides strong support for its stability and airflow in practical applications. Meanwhile, the lower two sides of the filter element 100 are inclined edges with a certain angle towards the central axis of the filter element. This design makes the filter element 100 more flexible and convenient to install, and can easily adapt to the internal structure of different models of air purification devices. The upper two sides of the filter element 100 are far away from the central axis of the filter element, providing sufficient space for the exhaust assembly and ensuring that air can be smoothly drawn into the filter element 100 for filtration.

[0037] In another specific embodiment, the air purification device of this embodiment is an air purification device specifically designed for indoor environments. It includes components such as an exhaust assembly, a filter chamber, a filter element 100, a control assembly, and a ventilation assembly. The filter element 100 is installed inside the filter chamber. Through the action of the exhaust assembly, outside air is continuously drawn into the filter chamber. When the air passes through the filter element 100, it will be filtered sequentially by a pre-filter (first filter 121), a HEPA high-efficiency filter (second filter 122), and an activated carbon filter (third filter 123), thereby removing particulate matter and harmful substances. The filtered clean air is discharged by the ventilation assembly, providing users with a fresh and healthy indoor air environment.

[0038] The control component of the air purifier is responsible for monitoring the operating status of the entire device and making intelligent adjustments according to the user's actual needs. For example, when the indoor air quality is poor, the control component will automatically adjust the working power of the exhaust and ventilation components to improve air purification efficiency, while when the indoor air quality meets the standard, the control component will reduce the working power to save energy.

Since the present invention can be embodied in many forms without departing from the spirit or essence of the invention, it should be understood that the above embodiments are not limited to any of the foregoing details, but should be interpreted broadly within the spirit and scope defined by the appended claims. Therefore, all variations and modifications falling within the scope of the claims or their equivalents should be covered by the appended claims.
