[0019] Please see Figure 1 In this embodiment, the filter element 100 has a semi-circular arc shape. This design is not only aesthetically pleasing, but also facilitates installation and replacement in a limited space. The filter element 100 is mainly composed of three parts: a connecting component 110, a filter screen component 120, and a bottom cover 130. All three parts have a semi-circular arc structure, forming a symmetrical structure.

[0020] Please see Figure 2 In one specific embodiment, the connecting assembly 110 includes a top cover 111 and a connector 112. The connector 112 is designed with a specific locking device to ensure a secure connection with the air purifier, ensuring that the filter element 100 will not loosen or fall off during use. The top cover 111 is made of plastic material and has fine mesh holes distributed on it. These mesh holes ensure that air can smoothly enter the air purifier while preventing larger impurities from directly entering the filter element 100. The connecting assembly 110 has a semi-circular arc structure, which not only saves space but also makes the filter element 100 more flexible to install.

[0021] Please see Figure 3 , Figure 5 and Figure 6In one specific embodiment, the filter assembly 120 consists of a first filter 121 and a second filter 122. The first filter 121 is located at the lower end of the second filter 122. Air first enters the first filter 1221 for preliminary filtration, removing larger particles and impurities. The air that has passed through the preliminary filtration then enters the second filter 122 for secondary filtration. The first filter 121 is a pre-filter used to block larger dust and hair impurities, while the second filter 122 is a HEPA (High Efficiency Particulate Air) filter, which can effectively remove fine particulate matter in the air, such as PM2.5, bacteria, and viruses, for particles with a diameter of 0.3 micrometers (1 / 200th the diameter of a human hair).

[0022] Please see Figure 4 In one specific embodiment, the bottom cover 130, as the sealing component of the filter element 100, also adopts a semi-circular arc structure design, which perfectly matches the shape of the connector 112. The bottom cover 130 is made of plastic with mesh. These meshes ensure smooth airflow while also increasing the stability of the filter element. When the bottom cover 130 is connected to the connector 112, the filter assembly 120 is tightly clamped in the middle, forming a complete and efficient filtration system. In addition, the design of the bottom cover 130 also takes into account the need for easy disassembly and cleaning, making it more convenient and quick for users to maintain the filter element.

[0023] Furthermore, the filter element 100 features a semi-circular arc structure, a unique design that is not only aesthetically pleasing but also highly practical. The outer diameters of the semi-circular arc structures of the connecting components, filter assembly 120, and bottom cover 130 are matched, and their central axes are also matched and symmetrical about the central axis. This precise design ensures greater stability and reliability of the filter element during installation and use. In addition, the semi-circular arc structure of the filter element 100 is inclined downwards along the central axis, preferably at an angle of 120°-150°. This design allows air to flow more smoothly through the filter element, reducing airflow resistance and thus improving filtration efficiency.

[0024] like Figure 7 As shown, in one specific embodiment, the filter element 100 is composed of a number of small round holes. These small round holes are evenly distributed on the cross-section of the filter element. Each small round hole is connected to the center of the filter element through a slender support column (which may be represented as a slender structure like an electric wire or cable in the figure, but should actually be the internal support structure of the filter element). These support columns not only provide structural stability to the filter element, but the arrangement of the small round holes and support columns is also carefully designed to ensure that the air can fully contact the filter medium when passing through the filter element, thereby achieving a highly efficient filtration effect.

[0025] In one specific embodiment, an air purification device includes an exhaust assembly, a filter chamber, a filter element, a control zone assembly, and a ventilation assembly.

[0026] The exhaust system is responsible for drawing outside air into the device. It uses a combination of a high-efficiency motor and a fan to provide strong and stable suction, ensuring that air can smoothly enter the filter chamber.

[0027] The filter chamber provides ample installation space for the filter element 100. Inside the filter chamber, air can fully contact the filter element 100 and be filtered, thereby removing particulate matter and harmful substances.

[0028] The filter element 100 adopts the design structure and materials described in the above embodiments, and has extremely high filtration efficiency and stability. It can effectively remove harmful substances such as PM2.5, bacteria, and viruses from the air, providing users with a fresh and healthy indoor air environment.

[0029] The control unit is responsible for controlling the operation of the air purifier. It includes components such as the power button, fan speed adjustment knob, and operating mode selection switch, allowing users to easily adjust the operation of the air purifier according to their needs.

[0030] The ventilation unit is responsible for expelling filtered clean air from the air purifier. It employs an optimized duct design and a high-efficiency exhaust fan combination to ensure that clean air can be smoothly expelled from the device and diffused to every corner of the room.

[0031] In one specific embodiment, when the air purifier is turned on, the exhaust assembly starts first. A high-performance motor drives the fan blades to rotate at high speed, generating a strong suction force. This suction force draws outside air into the air purifier through the air inlet of the filter chamber.

[0032] More specifically, after the air is drawn in and enters the filter chamber, it first encounters the first filter 121 of the filter element 100. As a preliminary filtration layer, the first filter 121 can block larger dust, hair, and other impurities. The air that has passed through the preliminary filtration then enters the second filter 122, namely the HEPA high-efficiency filter. With its extremely fine fiber structure and high interception capacity, the HEPA filter can remove tiny particulate matter in the air, such as PM2.5, bacteria, and viruses. The semi-circular arc structure and inclined design of the filter element 100 optimize the airflow path, reduce resistance, and improve filtration efficiency.

[0033] Furthermore, the first filter screen 121 and the second filter screen 122 of the filter element 100 work together to effectively block harmful substances in the air. At the same time, the semi-circular arc structure and inclined design of the filter element 100 not only improve the filtration efficiency, but also ensure the stability of the filter element during installation and use. This design makes the filter element less susceptible to compression or deformation during installation, thereby ensuring its long-term filtration performance.

[0034] Furthermore, the control component is responsible for real-time monitoring of air quality and the usage of filter 100, and makes intelligent adjustments according to user needs. For example, when the air quality deteriorates, the control component will automatically adjust the suction power of the exhaust component to speed up the air purification process. At the same time, the control component can also remind users to replace the filter or perform other maintenance operations to ensure the continuous and efficient operation of the air purification device.

[0035] Furthermore, the clean air filtered by the filter element 100 is discharged from the air purification device by the ventilation component. The ventilation component adopts an optimized air duct design and a high-efficiency exhaust fan combination to ensure the flow rate and volume of clean air. The design of the air outlet allows the clean air to be evenly distributed to every corner of the room, thereby improving the overall indoor air quality.

[0036] Although the present invention has been described with reference to several typical embodiments, it should be understood that the terminology used is descriptive and exemplary, and not restrictive. 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.
