[0037] To make the objectives, technical solutions and advantages of the present utility model clearer, the technical solutions of the present utility model will be described in detail below. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. All other implementation manners obtained by those of ordinary skill in the art based on the embodiments of the present utility model without creative efforts shall fall within the scope protected by the present utility model.

[0038] See Figures 1 - 6 As shown, the present utility model provides a flexible activated carbon filter structure, including an outer support mesh cylinder 2. The outer support mesh cylinder 2 serves as an overall framework, and a first flexible filter structure 8 is arranged inside, as shown in the attached Figure 2 drawing. The two are closely attached. The scroll filter structure 1 is located inside the outer support mesh cylinder 2, and a number of filter insert cylinder structures 3 are evenly distributed in its spiral gap. The second opening groove 301 on the filter insert cylinder structure 3 ensures smooth gas flow between the structures.

[0039] See the attached Figure 1 drawing. End covers 4 are respectively installed at both ends of the outer support mesh cylinder 2 to play a closing role and ensure that the filtering process is carried out in a relatively closed space. An air inlet pipe 5 is arranged on one of the end covers 4 as the inlet for gas to enter the filter structure.

[0040] See the attached Figure 2 , Figure 3 and Figure 4 drawing. The central support cylinder structure 9 is located at the center of the scroll filter structure 1 to provide stable central support for the entire filter structure. Correspondingly, a central positioning column 10 is provided on the other end cover 4. The central positioning column 10 is accurately inserted into the central support cylinder structure 9 to achieve precise positioning of the central support cylinder structure 9 and ensure the stability and coaxiality of the entire filter structure.

[0041] See the attached Figure 5 and Figure 6As shown, the second flexible filter structure 11 is arranged on the inner side of the scroll filter structure 1, and is closely connected with the scroll filter structure 1, so as to further enhance the filtering effect. The third flexible filter structure 12 is located on the inner side of the filter embedded cylinder structure 3, and is seamlessly matched with the filter embedded cylinder structure 3, so as to comprehensively filter the gas from multiple levels and different positions, effectively remove impurities and odors, and improve the filtering efficiency and quality.

[0042] See the instruction manual Figure 2 As shown, the outer support mesh tube 2 is made of stainless steel mesh material, which has good strength and corrosion resistance, and provides a stable external frame for the entire filter structure. The first flexible filter structure 8 includes a first mesh cloth 801, wherein the first mesh cloth 801 is directly attached to the inner side of the outer support mesh tube 2, and plays a role in preliminary filtering and supporting the first sheet-like activated carbon layer 802. The first sheet-like activated carbon layer 802 is located on the side of the first mesh cloth 801 away from the outer support mesh tube 2, and can effectively absorb impurities and odors in the gas to achieve initial deep purification.

[0043] The scroll filter structure 1 is also made of stainless steel mesh material, and a plurality of first opening grooves 101 are evenly distributed on the outer side thereof. These opening grooves are used for gas to be discharged from the inside of the scroll filter structure 1 .

[0044] See the instruction manual Figure 5 As shown, the second flexible filter structure 11 is tightly attached to the inner wall of the scroll filter structure 1, the second mesh cloth 1101 serves as a carrier, and the evenly distributed second sheet activated carbon layer 1102 further adsorbs and purifies the gas after preliminary filtration by the scroll filter structure 1, thereby enhancing the filtration effect.

[0045] The two end caps 4 are respectively installed at the two ends of the outer supporting mesh cylinder 2, and the edge grooves 6 on the outer edges of the end caps 4 are tightly embedded with the outer supporting mesh cylinder 2 to form a sealed fit, effectively preventing gas leakage and ensuring the stability and efficiency of the filtration process.

[0046] The positioning boss 7 provided on the end cover 4 corresponds one-to-one with the filter embedded cylinder structure 3. During the installation process, the positioning boss 7 can be accurately embedded in the corresponding position of the filter embedded cylinder structure 3 to achieve rapid positioning, thereby ensuring the accurate installation of the filter embedded cylinder structure 3 in the gap of the scroll filter structure 1, thereby ensuring the stability and filtering effect of the entire filtering structure.

[0047] See the instruction manual Figure 6 As shown, the third mesh cloth 1201 of the third flexible filter structure 12 is closely attached to the inner wall of the filter cartridge structure 3, and the third sheet-like activated carbon layer 1202 is distributed on the third mesh cloth 1201. When the gas enters the interior of the filter cartridge structure 3 through the second open slot 301, the third flexible filter structure 12 can adsorb and filter the gas again, further improving the filtering accuracy.

[0048] The inner sleeve 901 of the central support cylinder structure 9 is located at the center of the scroll filter structure 1. The third opening groove 902 on its outer sidewall facilitates the passage of gas, ensuring the smooth outflow of gas in the central area of the filter structure. The catch 903 on the outer sidewall of the inner sleeve 901 is tightly clamped with the inner edge of the scroll filter structure 1, effectively fixing the position of the scroll filter structure 1, enhancing the stability of the entire filter structure, and ensuring the coordinated and stable operation of each component during the working process.

[0049] Working principle:

[0050] During use, the gas containing impurities enters the central support cylinder structure 9 inside the center of the scroll filter structure 1 through the intake pipe 5 on the end cap 4. When spirally led out from the center to the outside, it is finally discharged after secondary filtration by the first flexible filter structure 8 inside the outer support mesh cylinder 2. The gas discharges from the scroll filter structure 1 through the first opening groove 101 on the outside of the scroll filter structure 1 and is finally discharged after being filtered again by the first flexible filter structure 8.

[0051] The filter insert cylinder structure 3 is located in the spiral gap of the scroll filter structure 1. Its second opening groove 301 allows gas to enter the inside of the filter insert cylinder structure 3, realizing gas diversion and further filtration.

[0052] The first flexible filter structure 8, the second flexible filter structure 11, and the third flexible filter structure 12 respectively include a first sheet activated carbon layer 802, a second sheet activated carbon layer 1102, and a third sheet activated carbon layer 1202. When the gas passes through these structures, the activated carbon layer adsorbs minute impurities such as peculiar smell and harmful gases in the gas, realizing deep purification and filtration.

[0053] There is a third opening groove 902 on the outer sidewall of the inner sleeve 901 of the central support cylinder structure 9, which can allow the gas to be filtered to pass through and enter the scroll filter structure 1. The catch 903 on the inner sleeve 901 clamps the inner edge of the scroll filter structure 1 to ensure the stability of the structure.

[0054] The above is only the specific implementation manner of the present utility model, but the protection scope of the present utility model is not limited thereto. Any person skilled in the art within the technical scope disclosed by the present utility model can easily think of changes or substitutions, which should all be covered within the protection scope of the present utility model. Therefore, the protection scope of the present utility model shall be subject to the protection scope of the claimed rights.
