An inclined guide plate 602 is fixed at the bottom of the empty slot 601, and the guide plate 602 can guide the elastic telescopic frame 603. The guide plate 602 is slidably connected with the elastic telescopic frame 603, and the elastic telescopic frame 603 can fasten the pre-filter 2, the air filter 3 and the activated carbon net 4, and the elastic telescopic frame 603 is an inverted L-shaped structure, and a connecting plate 604 is fixed at one end of the elastic telescopic frame 603. The connecting plate 604 can adjust the screw rod 606 and the elastic telescopic frame 603. The top of the connecting plate 604 is rotatably connected with an adjusting screw rod 606. The adjusting screw rod 606 can adjust the horizontal height of the elastic telescopic frame 603 through the connecting plate 604. The outer side of the adjusting screw rod 606 is connected to a support plate 605 through a thread. The support plate 605 can support the adjusting screw rod 606, and the support plate 605 is fixed on the mounting groove 5.

[0022] like Figure 2 As shown, an exhaust fan 7 is arranged between the pre-filter 2 and the air filter 3, so as to facilitate the extraction of external air into the machine body 1 through the exhaust fan 7, and there are two groups of exhaust fans 7.

[0023] like Figure 2 As shown, a U-shaped mounting seat 8 is symmetrically arranged between the air filter 3 and the activated carbon net 4, and the ultraviolet lamp 9 can be supported by the mounting seat 8.

[0024] like Figure 2 As shown, a UV lamp 9 is fixed on the mounting base 8, and there are two groups of UV lamps 9, which facilitates the UV lamps 9 to irradiate and sterilize the gas.

[0025] like Figure 1As shown, multiple groups of air holes 10 for air intake and exhaust are symmetrically opened on the two side walls of the body 1, so that the gas can enter the body 1 through the air holes 10 on one side for filtration, and then the filtered gas can be discharged through the air holes 10 on the other side.

[0026] like Figure 1 As shown, a top cover 11 is installed on the top of the body 1, and the top cover 11 and the body 1 are a split structure, which makes it convenient for the top cover 11 to seal the top of the body 1, and the user can open the top cover 11 to clean and replace the pre-filter 2, the air filter 3 and the activated carbon net 4.

[0027] like Figure 1 As shown, an operation panel 12 is fixed to the top of the top cover 11 , so that the user can control the operation of the device through the operation panel 12 .

[0028] Working principle of the device: When the device is used, the user controls the device to work through the operation panel 12. First, the exhaust fan 7 in the body 1 works, which can allow the outside air to enter the body 1 through the air holes on one side of the body 1. During the flow of gas in the body 1, it first passes through the pre-filter 2, and captures large particles such as dust, pet hair, etc. through the pre-filter 2 to protect the subsequent filter from being affected by excessively large particles. Then it moves to the air filter 3, which can effectively capture tiny particles in the air, including dust, pollen, mold, bacteria, etc., and moves to the activated carbon net 4 after filtering. During the movement, it is irradiated and sterilized by the ultraviolet lamp 9 on the mounting seat 8. Finally, the activated carbon net 4 absorbs odors, smoke, volatile organic compounds (VOCs) and other harmful gases in the air, and the filtered gas is discharged from the body 1 from the other side to complete the air purification.

[0029] After long-term use, the user can open the top cover 11 to clean or replace the pre-filter 2, air filter 3 and activated carbon filter 4. After reinstalling them into the body 1, the user rotates the adjusting screw 606 to make the adjusting screw 606 rotate along the support plate 605. During the rotation, the elastic telescopic frame 603 is driven by the connecting plate 604 to move along the guide plate 602 at the empty groove 601. During the movement, the elastic telescopic rod will continuously stretch when in contact with the guide plate 602 and enter the installation groove 5 through the empty groove 601, thereby fastening the pre-filter 2, the high-efficiency HEPA filter and the activated carbon filter to prevent them from shaking due to airflow, thereby preventing noise and improving the user experience.

[0030] The above are only further embodiments of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes within the scope disclosed by the present invention according to the technical solution and concept of the present invention, which fall within the protection scope of the present invention.
