Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.

[0027] Please see Figure 1-5 This utility model provides a technical solution:

[0028] An adjustable filter for an air purifier includes a movable base box 1. A control key 2 is fixedly connected to the front of the outer surface of the movable base box 1. Movable wheels 3 are inlaid around the lower end of the movable base box 1. A filter replacement structure 4 is movably connected to the inner thread of the movable base box 1. A top cover mounting structure 5 is provided at the center of the top of the filter replacement structure 4.

[0029] In this embodiment, the filter element replacement structure 4 includes a filter element metal mesh shell 41. A threaded ring post 42 is fixedly connected to the lower end of the filter element metal mesh shell 41. A central metal filter screen 43 is fixedly connected to the middle of the inner lower wall of the filter element metal mesh shell 41. A filter element placement cavity 44 is formed between the filter element metal mesh shell 41 and the central metal filter screen 43. A replaceable filter element assembly 45 is movably inserted into the filter element placement cavity 44. Screws 46 are threadedly connected to both the front and rear of the outer surface of the filter element metal mesh shell 41. The threaded ring post 42 is located inside the movable base box 1 and is detachably connected to the movable base box 1. The lower end face of the filter element metal mesh shell 41 is flush with the upper end face of the movable base box 1. The replaceable filter element assembly 45 includes a metal filter inner screen 451. An outer metal filter screen 452 is fixedly connected to the middle of the lower inner wall of the metal filter inner screen 451. A filter element adsorption chamber 453 and a potassium permanganate particle chamber 454 are sequentially opened from the inside to the outside between the metal filter inner screen 451 and the outer metal filter screen 452. A HEPA filter block 455 and an activated carbon block 456 are movably inserted from the outside to the inside of the filter element adsorption chamber 453. The HEPA filter block 455 and the activated carbon block 456 are not fixed. The metal filter inner screen 451 is movably inserted into the filter element placement chamber 44. The inner wall of the outer metal filter screen 452 is in close contact with the outer surface of the middle metal filter screen 43 but is not fixed.

[0030] The above solution allows for the following steps: When the filter element needs to be replaced, first unscrew the screws 46 on the filter element metal mesh shell 41, then remove the filter element metal mesh shell 41 from the movable base box 1 via the threaded ring post 42. Next, remove the replaceable filter element assembly 45 from the filter element placement chamber 44. The HEPA filter block 455 and activated carbon block 456 inside the replaceable filter element assembly 45 can be flexibly replaced or added or removed according to different pollution levels and types. The potassium permanganate particles in the potassium permanganate particle chamber 454 can also be replaced as needed. During installation, the operation is reversed. Thus, all accessories work together, solving the shortcomings of existing filter elements. The design of the replaceable filter element assembly 45 greatly improves the adaptability of the filter element, allowing the purification material to be adjusted according to the actual pollution situation. At the same time, only the parts inside the replaceable filter element assembly 45 need to be replaced, reducing replacement costs. The metal mesh shell and filter screen are easy to recycle, reducing the pollution of the environment by old filter elements and ensuring the continuous and efficient use of the air purifier.

[0031] In this embodiment, the upper cover mounting structure 5 includes a sealing cover 51. A through hole 52 is opened in the middle of the upper end of the sealing cover 51. Screw holes 53 are opened in the front and rear of the outer surface of the sealing cover 51. A fan assembly 54 is movably inserted into the through hole 52. The inner upper wall of the sealing cover 51 tightly abuts against the upper end of the filter element metal mesh shell 41. The sealing cover 51 is detachably connected to the filter element metal mesh shell 41 through two screw holes 53 and two screws 46. The fan assembly 54 includes an annular plate 541. A silent fan 543 is fixedly connected to the lower end of the annular plate 541. A silent fan 543 is installed in the middle of the lower end of the annular plate 541. The silent fan 543 is located in the annular insert 542. The area of ​​the annular plate 541 is equal to the area of ​​the upper end surface of the filter element metal mesh shell 41. The silent fan 543 is movably inserted into the upper part of the through hole 52. The diameter area of ​​the through hole 52 is equal to the inner diameter area of ​​the middle metal filter screen 43.

[0032] The above solution involves aligning the annular plate 541 of the fan assembly 54 with the through hole 52 of the sealing cover 51 during installation. The silent fan 543 is then inserted into the upper part of the through hole 52. Next, the sealing cover 51 is placed on top of the filter metal mesh shell 41, ensuring the inner upper wall of the sealing cover 51 is firmly against the filter metal mesh shell 41. Then, the screws 46 are screwed into the screw holes 53 on the outer surface of the sealing cover 51 and the corresponding screw holes 53 on the filter metal mesh shell 41, thus achieving a fixed connection between the sealing cover 51 and the filter metal mesh shell 41. Removal is achieved by reversing the process. This greatly simplifies the installation process. Non-professional users do not need to disassemble complex outer shell components; they can complete the installation connection between the fan assembly 54 and the filter metal mesh shell 41 simply by aligning, inserting, and screwing the screws 46. The operation is convenient and solves the problems of cumbersome installation and inaccessibility to non-professional users.

[0033] It should be noted that this utility model is an adjustable filter for an air purifier. During use, the air purifier is first activated via control button 2. The movable wheels 3 facilitate moving the purifier to the desired position. Air enters the replaceable filter structure 4 from below for purification. In the replaceable filter structure 4, the air first passes through the central metal filter 43 for initial filtration of large particles. Then, it enters the replaceable filter assembly 45. Within the replaceable filter assembly 45, the HEPA filter block 455 filters fine particles, the activated carbon block 456 adsorbs harmful gases, and the potassium permanganate particles in the potassium permanganate particle chamber 454 further oxidize and decompose harmful substances. The purified air then passes through the fan assembly 5. The silent fan 543 accelerates the upward exhaust. When the filter needs to be replaced, unscrew the screw 46, rotate the threaded ring 42 to remove the filter metal mesh shell 41 from the movable base box 1, and take out the replaceable filter element assembly 45 for component replacement. When replacing the top cover mounting structure 5, unscrew the screw 46 to separate the sealing cover 51 from the filter metal mesh shell 41. In summary, the replaceable component design of the filter element replacement structure 4 enables targeted purification of different pollutants and facilitates component replacement to reduce costs. The top cover mounting structure 5 simplifies the installation process and effectively solves the problems of complex filter element installation and replacement and poor compatibility, bringing users an efficient and convenient air purification experience.
