Detailed implementation manners

[0024] In the following, only some exemplary embodiments are simply described. As those skilled in the art can recognize, the described embodiments can be modified in various different ways without departing from the spirit or scope of the present utility model. Therefore, the drawings and the description are considered to be exemplary in nature rather than restrictive.

[0025] The embodiments of the present utility model will be described in detail below with reference to the drawings.

[0026] As Figures 1-4 shown, the embodiment of the present utility model provides a multi-layer filtered air purification device, which is composed of a main body mechanism 10 and a limiting mechanism 20.

[0027] The main body mechanism 10 includes a front cover 11, a connecting plate 16 and a fixing ring 17. Four connecting plates 16 are equidistantly distributed and fixedly connected to one side of the front cover 11, and one side of the connecting plate 16 is fixedly connected to the fixing ring 17. The front cover 11 cooperates with the connecting plate 16 and the fixing ring 17 to provide an installation space for the outer filter element 32 and the inner filter element 23. The outer filter element 32 is arranged between the connecting plates 16. First connecting rings 33 and second connecting rings 34 are respectively fixedly connected to both sides of the outer filter element 32. First bolts 18 are threadedly connected to one side of the front cover 11 at equal intervals. One end of the first bolt 18 is threadedly connected to the first connecting ring 33. Second bolts 19 are threadedly connected to one side of the fixing ring 17 at equal intervals. One end of the second bolt 19 is threadedly connected to the second connecting ring 34. The first connecting ring 33 and the second connecting ring 34 are respectively connected to the front cover 11 and the fixing ring 17 through the first bolts 18 and the second bolts 19, which is convenient for the installation and fixation of the outer filter element 32. A connecting pipe 12 is integrally formed on one side of the front cover 11. Threads are provided on the surface of the connecting pipe 12, which is convenient for connecting with an air purifier, enabling air to flow from inside to outside for purification. In order to enhance the sealing performance of the connection, a sealing ring 13 is sleeved on one side of the connecting pipe 12.

[0028] In one embodiment, in order to facilitate the fixation of the position of the front cover 11, fixing plates 14 are fixedly connected to one side of the front cover 11 at equal intervals, and fixing holes 15 are symmetrically formed inside the fixing plates 14.

[0029] In one embodiment, in order to facilitate the sterilization treatment of the discharged air, ultraviolet lamp strips 31 are fixedly connected to both sides of the connecting plate 16.

[0030] The limiting mechanism 20 includes a rear cover 21. The rear cover 21 is engaged with the fixing ring 17, and third bolts 22 are threadedly connected to one side of the rear cover 21 at equal intervals. One end of the third bolt 22 is threadedly connected to the fixing ring 17, which is convenient for connecting and fixing the rear cover 21 and the fixing ring 17. An inner filter element 23 is arranged inside the outer filter element 32. Clamping blocks 24 are fixedly connected to one side of the inner filter element 23 at equal intervals. Card slots 25 are formed at equal intervals on one side of the front cover 11. The clamping blocks 24 are engaged with the front cover 11 through the card slots 25, so that one side of the inner filter element 23 is connected to the front cover 11 and the inner filter element 23 is prevented from deflecting during installation. One side of the inner filter element 23 is engaged with the rear cover 21, and the inner filter element 23 is limited by the rear cover 21, so that the inner filter element 23 and the outer filter element 32 are installed independently.

[0031] In one embodiment, in order to prevent the inner filter element 23 from being damaged due to collision with the outer filter element 32, a limiting ring 26 is sleeved on one side of the inner filter element 23, and one side of the limiting ring 26 is fixedly connected to the front cover 11.

[0032] When the utility model works: Connect the connecting pipe 12 on one side of the front cover 11 with an air purifier, and fix the position of the front cover 11 by using fixing screws to cooperate with the fixing holes 15 on the fixing plate 14, so that air flows into the inner filter element 23 through the connecting pipe 12 and is discharged from the inside to the outside. The inner filter element 23 cooperates with the outer filter element 32 for multi-layer filtration treatment. When the air is discharged, the ultraviolet lamp strip 31 on one side of the connecting plate 16 sterilizes the air. When it is necessary to disassemble the inner filter element 23, rotate the third bolt 22 to remove it, remove the rear cover 21 from the fixing ring 17, and pull the inner filter element 23 outwards so that the clamping block 24 on one side of the inner filter element 23 disengages from the clamping groove 25, then the inner filter element 23 can be removed. When it is necessary to disassemble the outer filter element 32, remove the rear cover 21 and remove the first bolt 18 and the second bolt 19, and then pull the outer filter element 32 outwards to take it out.

[0033] The above is only the specific implementation manner of the utility model, but the protection scope of the utility model is not limited thereto. Any person skilled in the art in the technical field disclosed by the utility model can easily think of various changes or substitutions within the technical scope disclosed by the utility model, and these should all be covered within the protection scope of the utility model. Therefore, the protection scope of the utility model should be subject to the protection scope of the claims.
