[0021] Please see Figures 1-5 This utility model provides a technical solution: an easy-to-use air treatment filter element, including a connecting block 1 and a filter device 2, wherein the connecting block 1 and the filter device 2 are connected by a snap-fit ​​component 3.

[0022] The following section will explain the specific settings and functions of its card-connecting component 3.

[0023] In this embodiment: the snap-fit ​​assembly 3 includes a fixed frame 31, the top of the fixed frame 31 is fixedly connected to the bottom of the connecting block 1, the inner wall of the fixed frame 31 is provided with a connecting groove 32, a snap-fit ​​groove 35 is provided through the bottom of the fixed frame 31 and the connecting groove 32, a connecting cylinder 33 is snap-fitted inside the connecting groove 32, the bottom of the connecting cylinder 33 is fixedly connected to the top of the filter device 2, and a snap-fit ​​block 34 is provided at the upper end of the outer surface of the connecting cylinder 33, the snap-fit ​​block 34 and the connecting groove 32 cooperate with each other.

[0024] The aforementioned components achieve the following effect: During actual installation, the operator aligns the locking block 34 on the connecting cylinder 33 with the slot 35, inserts the connecting cylinder 33 into the fixing frame 31 along the direction of the slot 35, and then rotates the connecting cylinder 33 clockwise. The locking block 34 will enter the connecting groove 32 as the connecting cylinder 33 rotates, forming a stable locking structure within the connecting groove 32, thereby achieving rapid installation of the connecting block 1 and the filter device 2. For disassembly, simply rotate the connecting cylinder 33 counterclockwise to disengage the locking block 34 from the connecting groove 32, and then pull the connecting cylinder 33 out of the slot 35 to separate the connecting block 1 from the filter device 2. The operation is simple and quick, greatly improving the efficiency of filter element installation and removal.

[0025] Specifically, the filter device 2 includes an upper connecting cover 21, which is fixedly connected to the bottom of the connecting cylinder 33. The filter cylinder 22 is snapped into the inside of the upper connecting cover 21, and the lower end of the filter cylinder 22 is snapped into the lower connecting cover 23. An air outlet 24 is provided at the bottom end of the lower connecting cover 23.

[0026] The aforementioned components achieve the following effect: the upper connecting cover 21 and the lower connecting cover 23 are fixed from the upper and lower ends of the filter cartridge 22, respectively, forming a closed filtration space, ensuring that the air entering the filtration device 2 can be fully filtered by the filter cartridge 22. At the same time, this snap-fit ​​method makes the disassembly and assembly of the filter cartridge 22 very convenient. When the filter cartridge 22 reaches the end of its service life or is damaged, it can be directly removed from the upper connecting cover 21 and the lower connecting cover 23 for replacement, without needing to replace the entire filtration device 2, thus reducing maintenance costs.

[0027] Specifically, the filter cartridge 22 includes a filter housing 221 and an inner filter screen 222, with a filter element body 223 disposed between the filter housing 221 and the inner filter screen 222.

[0028] The aforementioned components achieve the following effects: the filter housing 221 protects the inner filter screen 222 and the filter element body 223 from damage during use. The inner filter screen 222 intercepts larger particulate impurities in the atmosphere, such as dust and gravel, thus initially purifying the air. The filter element body 223 plays a crucial role in the deep filtration and adsorption of fine particles and harmful gases in the atmosphere. Through its internal filter materials and structure, it effectively removes pollutants from the atmosphere, ensuring the cleanliness of the output gas.

[0029] Specifically, the lower end of the connecting cylinder 33 is fixedly connected to the upper processing chamber 331, and the lower end of the outer surface of the upper processing chamber 331 is threadedly fixedly connected to the lower processing chamber 332. The lower processing chamber 332 is fixedly connected to the upper connecting cover 21.

[0030] Specifically, the lower end of the outer surface of the upper processing cavity 331 and the inner end of the lower processing cavity 332 are both provided with threads, and an adsorption sponge is placed inside the upper processing cavity 331.

[0031] The aforementioned components achieve the following effect: the upper treatment chamber 331 and the lower treatment chamber 332 are connected by threads to form an independent pretreatment space. This connection method facilitates opening the treatment chamber. When the internal adsorption sponge needs to be replaced, simply rotate the lower treatment chamber 332 counterclockwise to separate it from the upper treatment chamber 331, making it convenient and quick to replace the adsorption sponge. Simultaneously, the upper treatment chamber 331 is fixedly connected to the connecting cylinder 33, and the lower treatment chamber 332 is fixedly connected to the upper connecting cover 21, ensuring the stability of the entire filtration system structure. This allows the air to undergo preliminary adsorption treatment within the treatment chamber before entering the filter device 2 through the connecting cylinder 33, further improving the filtration effect.

[0032] Specifically, a fixing ring 11 is fixedly connected to the upper end of the outer surface of the connecting block 1, and the outer surface of the fixing ring 11 is provided with friction texture.

[0033] The effect achieved by the above components is that the fixing ring 11 provides a stable point of force for the connection between the filter element and the air treatment equipment.

[0034] Specifically, a filter plate 12 is fixedly connected to the inner wall of the connecting block 1, and a top cover 13 is fixedly connected to the top of the connecting block 1.

[0035] The effect achieved by the above components is that the filter plate 12 can perform preliminary filtration of the air entering the connecting block 1, intercept larger particles of impurities in the air, and prevent these impurities from entering the subsequent filtration device 2 and causing blockage or damage to components such as the filter cartridge 22, thus playing a certain protective role.

[0036] Working Principle: When the air treatment equipment is running, outside air first enters through the top of connecting block 1 and undergoes preliminary filtration through the filter plate 12 on the inner wall of connecting block 1, intercepting larger particulate impurities. Then, the air enters connecting cylinder 33, where it is partially purified by the adsorption sponge in the upper treatment chamber 331 at the lower end of connecting cylinder 33, where some odors, moisture, and harmful gas molecules are adsorbed. Next, the air enters the filtration device 2, passing sequentially through the inner filter screen 222 and the filter element body 223 of filter cylinder 22. The inner filter screen 222 intercepts larger particulate impurities, while the filter element body 223 performs deep filtration and adsorption, removing fine particles and harmful gases. The clean air treated by filter cylinder 22 is discharged from the outlet 24 of the lower connecting cover 23, completing the entire air treatment process.

[0037] When the filter element needs maintenance or component replacement, the connecting block 1 and the filter device 2 can be quickly disassembled by rotating the connecting cylinder 33 and using the snap-fit ​​assembly 3. The filter cartridge 22, adsorption sponge and other components can be replaced and maintained to ensure that the filter element always maintains good filtration performance.
