[0022] The utility model is further described below in conjunction with the accompanying drawings and implementation modes.

[0023] Please refer to Figure 1 , Figure 2 , Figure 3 and Figure 4 ,in Figure 1 A schematic structural diagram of a preferred embodiment of a multi-stage dynamic indoor air purification device provided by the utility model; Figure 2 for Figure 1 A schematic diagram of the structure of the first channel portion is shown;

[0024] Figure 3 for Figure 2 A schematic diagram of the structure of area A is shown; Figure 4 for Figure 1The schematic diagram of the overall structure of the purification box shown is a multi-stage dynamic purification device for indoor air, comprising: a purification box 1, a purification component 2 is arranged on the top of the inner side of the purification box 1, and a cleaning component 3 is arranged on the inner side of the purification component 2;

[0025] The purification component 2 includes a first channel 21 opened at the top of the inner side of the purification box 1, the left side of the top of the first channel 21 is connected to an air inlet 22, the top of the air inlet 22 is located on the left side of the top of the purification box 1, and the top of the air inlet 22 is covered with a first filter 23;

[0026] The first filter screen 23 is provided to prevent larger foreign matter from entering the purification box 1 .

[0027] The cleaning assembly 3 includes a rotating screw 31 arranged at the bottom of the inner wall of the first channel 21. The top of the rotating screw 31 passes through the inner wall of the first channel 21 and extends to the top of the purification box 1. A rotating handle 32 is provided at the top of the rotating screw 31. A cleaning brush 33 is provided on the peripheral side of the rotating screw 31 so that it can slide up and down along its height direction.

[0028] When cleaning is needed, the rotating handle 32 drives the rotating screw 31 to rotate, thereby driving the cleaning brush 33 to move to one side in its direction, so that the right side of the cleaning brush 33 brushes away the dust on the surface of the second filter 24.

[0029] A second filter screen 24 is disposed on the inner wall of the first channel 21 and on the right side of the cleaning brush 33 . The left side of the second filter screen 24 is tightly fitted to the right side of the cleaning brush 33 . A suction fan 25 is disposed on the right side of the bottom of the inner wall of the first channel 21 .

[0030] The operation of the suction fan 25 allows air to enter through the air inlet 22 and then be filtered by the second filter 24 before being discharged into the second channel 26 .

[0031] The purification component 2 also includes a second channel 26 arranged at the bottom of the suction fan 25 and located at the bottom of the inner side of the purification box 1. An ultraviolet lamp 27 is arranged at the top of the inner wall of the second channel 26. The left side of the bottom of the second channel 26 is connected to the outside world. Two purification layers 28 are arranged on the left side of the bottom of the inner wall of the second channel 26. A control mechanism 29 is arranged at the top of the second channel 26 and located on the inner side of the purification box 1.

[0032] The harmful substances such as bacteria in the air are removed by turning on the ultraviolet lamp 27, and the air quality is deeply improved through the two purification layers 28.

[0033] A limit slide bar 34 is vertically arranged at the bottom of the inner wall of the first channel 21 and on the left side of the rotating screw rod 31 , and the peripheral side surface of the limit slide bar 34 is slidably connected to the left side of the cleaning brush 33 .

[0034] The bottom of the inner wall of the first channel 21 and the bottom on the left side of the second filter 24 are connected with an inverted cone opening 35, and a dust collecting box 36 is provided on the back of the purification box 1 and at the bottom end of the inverted cone opening 35 so as to be slidable forward and backward.

[0035] The dust brushed away by the cleaning brush 33 will fall into the inverted cone opening 35 at the bottom and finally fall into the dust box 36. Due to the shape of the inverted cone opening 35, the dust is not easily raised again after entering the dust box 36. When the dust box 36 needs to be cleaned, it can be pulled out by simply pulling it backwards for cleaning.

[0036] The cleaning assembly 3 also includes a third filter plate 37 which is slidable left and right and is arranged on the inner wall of the second channel 26 and is located below the ultraviolet lamp 27. The left side of the third filter plate 37 passes through the inner side of the second channel 26 and extends to the right side of the purification box 1.

[0037] The filter holes of the three filter plates are reduced in sequence, so that the bearing capacity of each filter plate is controlled, which significantly improves the service life of the filter plates. The third filter plate 37 is the last filter plate. Since it is detachable and cleanable, when the purification efficiency of the purification box 1 is reduced, only the third filter plate 37 needs to be replaced or cleaned to restore the purification effect of the purification box 1 to a large extent.

[0038] The working principle of the indoor air multi-stage dynamic purification device provided by the utility model is as follows:

[0039] Step 1: When in use, the control mechanism 29 drives the suction fan 25 to rotate, so that air enters from the air inlet 22 and is then discharged into the second channel 26 after being filtered by the second filter 24. In this process, the first filter 23 prevents larger impurities and foreign objects from entering the purification box 1, and the second filter 24 isolates fine fluff and dust on its left side. When the air reaches the second channel 26, the ultraviolet lamp 27 is turned on to remove harmful substances such as bacteria in the air, and the air quality is improved through the depth of the two purification layers 28. Finally, the air is discharged from the bottom of the left side of the purification box 1;

[0040] Step 2: When it is necessary to clean the filter plate inside the purification box 1, the rotating screw 31 is driven to rotate by rotating the handle 32, and the setting of the limiting slide bar 34 is used to drive the cleaning brush 33 to move to one side in its direction, so that the right side of the cleaning brush 33 brushes away the dust on the surface of the second filter screen 24, and the brushed dust will fall into the inverted cone mouth 35 at the bottom, and finally fall into the dust collecting box 36. Due to the setting of the shape of the inverted cone mouth 35, the dust is not easy to be raised again after entering the dust collecting box 36. When the dust collecting box 36 needs to be cleaned, it only needs to be pulled back to pull out the dust collecting box 36 for cleaning. When the purification efficiency of the purification box 1 is reduced, it is only necessary to replace or clean the third filter plate 37 to restore the purification effect of the purification box 1 to a large extent.

[0041] Compared with the related art, the indoor air multi-stage dynamic purification device provided by the utility model has the following beneficial effects:

[0042] When it is necessary to clean the filter plate inside the purification box 1, the rotating handle 32 drives the rotating screw 31 to rotate, and the setting of the limiting slide bar 34 drives the cleaning brush 33 to move to one side in its direction, so that the right side of the cleaning brush 33 brushes off the dust on the surface of the second filter 24, and the brushed off dust eventually falls into the dust collection box 36. When it is necessary to clean the dust collection box 36, you only need to pull it backwards to pull out the dust collection box 36 for cleaning. You can also replace or clean the third filter plate 37 to restore the purification effect of the purification box 1 to a greater extent.

[0043] Finally, it should be pointed out that the above embodiments are only representative examples of the present utility model. Obviously, the present utility model is not limited to the above embodiments, and there are many variations. Any simple modification, equivalent changes and modifications made to the above embodiments based on the technical essence of the present utility model should be considered to belong to the protection scope of the present utility model.
