[0035] Specifically, when the gas enters the housing 1, it is guided by the guide pipe 12, so that the gas first flows into the shunt pipe 13, diffuses in all directions in the shunt pipe 13, and then flows out of the overflow port 14 and evenly enters the housing 1 to fully contact the filter layer 2.

[0036] As shown in Figure 4 and Figure 5 , as a further embodiment of the housing: the housing 1 is provided with a support groove 15, and the support groove 15 cooperates with the dismounting frame 4.

[0037] Specifically, when the dismounting frame 4 is inserted into the housing 1, it will move along the support groove 15 and keep close to the support groove 15, and the dismounting frame 4 will be kept stable by the support groove 15.

[0038] As shown in Figure 4 and Figure 5 , as a further embodiment of the support groove: the support groove 15 is provided with a sealing strip 16, and the dismounting port 3 is provided with a sealing ring 17.

[0039] Specifically, the sealing strip 16 cooperates with the dismounting frame 4 to provide a sealing effect in the housing 1, and the sealing ring 17 cooperates with the dismounting frame 4 to provide a sealing effect at the dismounting port 3, ensuring sealing and ensuring filtering capacity.

[0043] Specifically, when the positioning pin 6 is inserted into the positioning groove 7 and engages with it, the inclined head 21 contacts the engaging inclined surface 22, causing the inclined head 21 to apply force to the engaging inclined surface 22, thereby pressing the disassembly frame 4 into the housing 1.

[0044] Please see Figure 5 As a further embodiment of the movable plate: the housing 1 is provided with a guide groove 23, and the movable plate 8 is provided with guide sliders 24 at both ends, with the guide groove 23 and the guide sliders 24 slidingly engaged.

[0045] Specifically, the movement of the movable plate 8 is guided by the cooperation of the guide groove 23 and the guide slider 24, so that the movable plate 8 slides stably in the housing 1.

[0046] Please see Figure 1 As a further embodiment of the shell: the shell 1 is provided with an observation port 25, and a transparent shell 26 is provided in the observation port 25.

[0047] Specifically, the observation port 25 and the transparent shell 26 work together to provide an observation structure made of transparent material, which makes it easy to determine the position of the disassembly frame 4 when it moves inside the shell 1, thereby making it easier to control the movement of the moving plate 8.

[0048] In summary, during the use or operation of the overall equipment:

[0049] The housing 1 provides the structure for connecting the device to external gas supply and collection equipment during use. When gas enters the housing 1, it is guided by the inlet pipe 12, flowing first into the diversion pipe 13, where it spreads outwards before exiting through the overflow port 14. The gas then evenly enters the housing 1, making full contact with the filter layer 2, ensuring its efficient use. The filter layer 2 separates the interior of the housing 1 for bacterial filtration. The two sets of filter layers 2 work together to improve filtration efficiency. The disassembly frame 4 is used to fix the filter layer 2, maintaining stability in conjunction with the support groove 15. When the filter layer 2 needs replacement, the disassembly port 3 engages with the disassembly frame 4. The disassembly frame 4 remains stable under the cooperation of the positioning pin 6 and the positioning groove 7. By pushing the control head 20 along the control port 19, the positioning pin 6 is controlled, separating it from the positioning groove 7 and retracting into the moving groove 5. This releases the fixation on the disassembly frame 4, allowing it to be pulled out and the filter layer 2 removed. 2. Remove the filter layer 2 for cleaning or replacement. Insert the disassembly frame 4 with the filter layer 2 into the housing 1 through the disassembly port 3. Guided and supported by the support groove 15, the disassembly frame 4 moves along the support groove and remains in close contact with it, ensuring stability. This allows the filter layer 2 to engage with the housing 1 for filtration. The positioning pin 6 engages with the positioning groove 7 and is stably inserted into the positioning groove 7 under the thrust of the pressure spring 18. When the positioning pin 6 engages with the positioning groove 7, the inclined head 21 contacts the mating inclined surface 22, applying force to the mating inclined surface 22 and pressing the disassembly frame 4 into the housing 1, thus fixing the disassembly frame 4 and completing the replacement and maintenance of the filter layer 2. This process does not require complete disassembly of the equipment, making it convenient to use. The sealing strip 16 engages with the disassembly frame 4 to provide a sealing effect inside the housing 1, and the sealing ring 17 engages with the disassembly frame 4 to provide a sealing effect at the disassembly port 3, ensuring a tight seal and maintaining filtration capacity.

[0050] When one set of filter layers 2 is disassembled, the other set of filter layers 2 remains undisassembled and continues to perform filtration. During the removal of the disassembly frame 4, the position of the disassembly frame 4 within the housing 1 is determined by the transparent observation structure provided by the observation port 25 and the transparent shell 26. When the disassembly frame 4 leaves the housing 1 but does not leave the disassembly port 3, it still retains its sealing ability by engaging with the sealing ring 17. The control block 9 is moved through the sliding port 11. Through the cooperation of the guide groove 23 and the guide slider 24, the moving plate 8 slides stably within the housing 1, moving the moving plate 8 to the disassembly port 3. Under the action of the sealing gasket 10, the moving plate 8 blocks the disassembly port 3, preventing leakage. Then, the disassembly frame 4 is completely pulled out, ensuring stable filtration when replacing the filter layer 2. Furthermore, the sealing gasket 10 also engages with the sliding port 11 to ensure a sealing effect.

[0051] Of all the solutions mentioned above, those involving the connection between two components can be selected according to the actual situation, such as welding, bolt and nut connection, bolt or screw connection, or other known connection methods, which will not be elaborated here. For all the fixed connections mentioned above, welding is preferred. Although embodiments of this utility model have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and variations can be made to these embodiments without departing from the principles and spirit of this utility model. The scope of this utility model is defined by the appended claims and their equivalents.
