[0023] The technical solutions of the present utility model will be explained and described below with reference to the accompanying drawings. However, the following embodiments are only preferred embodiments of the present utility model and not all of them. Other embodiments obtained by those skilled in the art based on the embodiments in the implementation methods without creative effort are all within the protection scope of the present utility model.

[0024] The following describes in detail, with reference to the accompanying drawings, an indoor air purification device with a multi-stage sterilization structure according to an embodiment of the present invention.

[0025] Example 1

[0026] For easier understanding, please refer to Figures 1 to 5 An embodiment of an indoor air purification device with a multi-stage sterilization structure provided by this utility model includes a bottom shell 1 and an upper shell 2. A rotating shaft 3 is fixedly installed on the bottom inner side of the bottom shell 1, and a support plate 4 is fixedly installed on the top of the rotating shaft 3. A particle filter screen 5 is sleeved on the inner side of the bottom shell 1. An exhaust fan 6 is fixedly installed on the inner side of the upper shell 2. Several return holes 7 are opened on one side of the upper shell 2. A dust removal component and an internal sterilization component are arranged between the bottom shell 1 and the upper shell 2. One end of the particle filter screen 5 abuts against the top of the support plate 4, and the other end of the particle filter screen 5 abuts against the bottom of the upper shell 2. The upper shell 2 and the bottom shell 1 are connected by threads.

[0027] The dust removal assembly includes a fixed frame 801, a driven gear 802, a dust removal brush 803, a dust discharge port 804, a drive motor 805, and a drive gear 806. The fixed frame 801 is rotatably connected to the outer wall of the rotating shaft 3. The driven gear 802 is fixedly installed in the middle of the fixed frame 801. The dust removal brush 803 is fixedly installed at the top of both ends of the fixed frame 801. The dust discharge port 804 is opened at the bottom of the inner side of the bottom shell 1. The drive motor 805 is fixedly installed inside the bottom shell 1. The drive gear 806 is fixedly installed at one end of the output shaft of the drive motor 805. The fixed frame 801 is located at the bottom of the support plate 4. The driven gear 802 meshes with the drive gear 806. The output end of the dust removal brush 803 abuts against the outer surface of the particle filter screen 5. The dust discharge port 804 is located at the bottom of the edge of the particle filter screen 5.

[0028] It should be noted that the cleaning brush 803 is used to clean the outer surface of the particle filter screen 5. After long-term use, dust will accumulate on the surface of the particle filter screen 5. At this time, the equipment is moved to an open area, and the drive motor 805 drives the fixed frame 801 to rotate through gear transmission. Then, the fixed frame 801 drives the cleaning brush 803 to rotate, and the cleaning brush 803 cleans the surface of the particle filter screen 5 to sweep away the external dust. The swept dust falls from the dust discharge port 804. The filter screen can be cleaned directly without removing it, which is convenient to use.

[0029] Example 2

[0030] In some embodiments, such as Figure 4 , Figure 5 As shown, the internal sterilization component includes a fixed cover 901, several air intake holes 902, a fixed cover 903, an activated carbon filter 904, a lamp holder 905, and an ultraviolet germicidal lamp 906. The fixed cover 901 is fixedly installed at the bottom of the upper shell 2. Several air intake holes 902 are opened on the side wall of the fixed cover 901. The fixed cover 903 is threadedly connected to the bottom of the fixed cover 901. The activated carbon filter 904 is fixedly installed between the fixed cover 901 and the fixed cover 903. The lamp holder 905 is fixedly installed on the inner side of the top of the fixed cover 901. The ultraviolet germicidal lamp 906 is fixedly installed on the bottom of the lamp holder 905. The fixed cover 901 is located inside the particulate filter 5. The diameter of the fixed cover 901 is smaller than the inner diameter of the particulate filter 5. The ultraviolet germicidal lamp 906 is located inside the activated carbon filter 904.

[0031] It should be noted that by further installing an activated carbon filter 904 and an ultraviolet germicidal lamp 906 inside the original particulate filter 5, the internal air will pass through the activated carbon filter 904 while being filtered by the particulate filter 5. After being adsorbed and filtered again by the activated carbon filter 904, the air will be sterilized by the ultraviolet germicidal lamp 906, thus performing multi-stage filtration and sterilization to improve the air filtration effect.

[0032] In this invention, both the particulate filter 5 and the activated carbon filter 904 are cylindrical filters with a filtration direction from the outside to the inside. All connections between the particulate filter 5 and the activated carbon filter 904 are sealed to ensure the filtration sealing of the particulate filter 5 and the activated carbon filter 904.

[0033] Working principle: During use, the exhaust fan 6 operates, drawing in external air through the outer side of the particulate filter 5. The particulate filter 5 filters the air, while the internal air passes through the activated carbon filter 904 for further adsorption and filtration. The air is then sterilized by the ultraviolet germicidal lamp 906, and finally returned to the room through the return hole 7. After prolonged use, dust accumulates on the surface of the particulate filter 5. The device is then moved to an open area, and the drive motor 805 rotates the mounting bracket 801 via gear transmission. The mounting bracket 801 then rotates the cleaning brush 803, which cleans the surface of the particulate filter 5, removing the external dust. The cleaned dust falls through the dust outlet 804. The filter can be cleaned directly without removal, making it convenient to use.

[0034] The above-described embodiments are only used to illustrate the technical solutions of this application, and are not intended to limit them. Although this application has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some of the technical features. Such modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the spirit and scope of the technical solutions of the embodiments of this application.
