[0023] In order to more clearly understand the above-mentioned objects, features and advantages of this utility model, the following further describes this utility model in conjunction with the drawings and embodiments. It should be noted that, without conflict, the embodiments of this application and the features in the embodiments can be combined with each other.

[0024] In the following description, many specific details are set forth to fully understand this utility model. However, this utility model can also be implemented in other ways different from those described herein. Therefore, this utility model is not limited by the specific embodiments disclosed in the following specification.

[0025] Example 1, as Figures 1 - 6 shown, this utility model provides a multi-stage activated carbon air purification device, including a main body 1 of the purification device. A slide rail 2 is fixed to the top of the main body 1 of the purification device. A cover plate 3 is slidably connected in the slide rail 2. The bottom of the cover plate 3 is slidably connected to the top of the main body 1 of the purification device and is provided with a groove 4. A limit component 5 for engaging with the groove 4 is provided on the main body 1 of the purification device; the main body 1 of the purification device includes a purification chamber 101, and a primary filter screen 102, an electrostatic dust removal net 103, a multi-stage activated carbon main body 104, a scent tablet 105 and a fan control unit 106 are respectively slidably connected to the top of the purification chamber 101.

[0026] The overall effect achieved by the entire Example 1 is that by setting the multi-stage activated carbon main body 104, harmful substances such as formaldehyde, benzene series and ammonia in the air can be efficiently removed, and some particles, dust and mold spores in the air can also be adsorbed to further purify the air. The scent tablet 105 made of natural plant spices makes the purified air have a fragrance, which can improve the indoor smell, soothe people's emotions and relax the body and mind. By operating the limit component 5, the cover plate 3 can be disassembled and assembled, so that people can replace and clean the primary filter screen 102, the electrostatic dust removal net 103, the multi-stage activated carbon main body 104 and the scent tablet 105 accordingly.

[0027] Example 2, as Figures 1 - 6 shown, one side wall of the purification chamber 101 close to the primary filter screen 102 is set as the air inlet, and one side wall of the purification chamber 101 close to the fragrance tablet 105 is set as the air outlet; the primary filter screen 102, the electrostatic dust removal net 103 and the multi-stage activated carbon body 104 are all located on one side of the fan control part 106, and the fragrance tablet 105 is located on the other side of the fan control part 106; the multi-stage activated carbon body 104 includes a coconut shell activated carbon layer 107 and a bituminous coal activated carbon layer 108, and the distance between the coconut shell activated carbon layer 107 and the electrostatic dust removal net 103 is relatively close; the limiting component 5 includes an arc-shaped groove 501 opened at the top of the purification chamber 101, a rotating rod 502 is rotatably connected between the two side walls of the arc-shaped groove 501 through a bearing, and a clamping block 503 is sleeved and fixed on the surface of the rotating rod 502; the clamping block 503 slides in the arc-shaped groove 501, a rubber pad 504 is fixed on one side wall of the purification chamber 101, one end of the rotating rod 502 sequentially penetrates through one side wall of the purification chamber 101 and the side wall of the rubber pad 504 and is fixed with an operation block 505, and the groove 4 is adapted to the arc-shaped groove 501; a rubber ring 506 is sleeved and fixed on the surface of the rotating rod 502 close to the operation block 505, and the opposite surfaces of the rubber ring 506 and the rubber pad 504 are in contact with each other.

[0028] The effect achieved by the entire Example 2 is that the air to be filtered enters the purification chamber 101 from the air inlet, and after being filtered by the primary filter screen 102, the electrostatic dust removal net 103 and the multi-stage activated carbon body 104 in sequence, the air that has removed dust and harmful gases needs to pass through the fragrance tablet 105 before it can be discharged from the air outlet, and then the clean air with fragrance can be discharged. Under the hierarchical filtration of the coconut shell activated carbon layer 107 and the bituminous coal activated carbon layer 108, harmful gases such as formaldehyde in the air can be further removed. Rotate the operation block 505 to drive the clamping block 503 to rotate accordingly, so that people can smoothly move or limit the cover plate 3 in cooperation with the groove 4 through different states of the clamping block 503, and people can replace and clean the fragrance tablet 105, the multi-stage activated carbon body 104, the electrostatic dust removal net 103, and the primary filter screen 102. The cooperation between the rubber ring 506 and the rubber pad 504 can increase the resistance to the easily movable rotating rod 502, so that the rotating rod 502 will not rotate easily, and the engagement between the clamping block 503 and the groove 4 can be effective for a long time.

[0029] Working principle: When using the main body 1 of the purification device, the operator starts the fan control unit 106 through the control panel. The outside air enters the purification chamber 101 from the air inlet, and the air in the purification chamber 101 flows from the air inlet towards the air outlet. First, it passes through the primary filter screen 102, and large particles and hairs are filtered by the primary filter screen 102. Subsequently, under the electrostatic adsorption of the electrostatic dust removal net 103, the dust in the air is adsorbed and retained. Finally, it reaches the multi-stage activated carbon main body 104. The air is first adsorbed by the microporous structure of the coconut shell activated carbon layer 107 to remove small molecule formaldehyde, and then the medium and large pores of the bituminous coal activated carbon layer 108 are used to further adsorb the remaining harmful gases. Finally, the air that has removed dust and harmful gases is blown onto the fragrance sheet 105 by the fan control unit 106, and the air is discharged after passing through the fragrance sheet 105 and having a fragrance. The operator can rotate the operation block 505 to rotate the clamping block 503 through the rotating rod 502 under the action of the bearing. And the operator can refer to the state of the clamping block 503 in the arc-shaped groove 501 and the groove 4 through the operation block 505. When the end of the clamping block 503 slides into the groove 4, the cover plate 3 can be limited. When the end of the clamping block 503 slides out of the groove 4, the cover plate 3 can slide on the top of the purification chamber 101, and with the cooperation of the slide rail 2, it is convenient for the operator to disassemble and assemble the cover plate 3.

[0030] The above is only the preferred embodiment of the present invention, and it is not a limitation of the present invention in other forms. Any person skilled in the art may use the disclosed technical content to make changes or modifications into equivalent embodiments with equivalent changes and apply them to other fields. However, as long as it does not depart from the technical solution content of the present invention, any simple modification, equivalent change and modification made to the above embodiments based on the technical essence of the present invention still belong to the protection scope of the technical solution of the present invention.
