The second threaded groove 1203, the second threaded hole 1204, and the second bolt 1205 are provided. A second L-shaped groove 1201 is provided on one side of the air intake pipe 8. A second L-shaped ring block 1202 is provided at one end of the mounting sleeve 12, and the second L-shaped ring block 1202 is located inside the second L-shaped groove 1201. The second L-shaped ring block 1202 and the second L-shaped groove 1201 are mutually engaged and slidably connected. A second threaded groove 1203 is provided on the outer side of the connecting pipe 3. Two sets of symmetrically arranged threaded grooves 1203 are provided. The second threaded groove 1203 is opened between the first L-shaped sliding groove 301 and the second annular mounting groove 10. A second threaded hole 1204 is opened on one side of the mounting sleeve 12. Two sets of second threaded holes 1204 are symmetrically arranged. The second threaded hole 1204 corresponds to the second threaded groove 1203. A second bolt 1205 is provided on the inner side of the second threaded hole 1204. Rotating the mounting sleeve 12 drives the second L-shaped ring block 1202 to rotate in the second L-shaped sliding groove 1201. The second L-shaped sliding groove 1201 limits the range of motion of the second L-shaped ring block 1202, ensuring that the mounting sleeve 12 and the air intake pipe 8 are relatively stable and rotatably connected. Rotating the mounting sleeve 12 makes the second threaded hole 1204 aligned with the second threaded groove 1203, and the second bolt 1205 is threaded into the second threaded hole 1204 and the second threaded groove 1203, thereby achieving the effect of stably connecting and fixing the air intake pipe 8 to one end of the connecting pipe 3.

[0026] When installing the connecting pipe 3, thread one end of the connecting pipe 3 into the first annular mounting groove 4, rotate the annular rotating plate 5 to drive the first L-shaped ring block 302 to rotate synchronously in the first L-shaped sliding groove 301, so that the first threaded hole 304 on the fixing plate 6 is aligned with the first threaded groove 303, and thread the first bolt 305 into the first threaded hole 304 and the first threaded groove 303, and fix the connecting pipe 3 to the generator body 1;

[0027] When installing the intake pipe 8, the annular mounting plate 11 is threaded into the second annular mounting groove 10, and at the same time, the sealing ring block 802 is embedded into the annular sealing groove 801. Then, the mounting sleeve 12 is rotated, which drives the second L-shaped ring block 1202 to rotate synchronously in the second L-shaped sliding groove 1201, so that the second threaded hole 1204 is aligned with the second threaded groove 1203. The second bolt 1205 is threaded into the second threaded hole 1204 and the second threaded groove 1203 to connect and fix the connecting pipe 3 and the intake pipe 8.

[0028] When the device is running, air flows through the intake pipe 8 and the connecting pipe 3. The filter layer 7 filters out dust and other impurities in the air. Then, the filtered gas enters the generator body 1 through the intake channel 2 to ensure the normal operation of the device.

[0029] Through the above steps, by setting the air intake channel 2 to ensure unobstructed airflow inside the generator body 1, and using the first annular mounting groove 4 to determine the installation position of the connecting pipe 3, one end of the connecting pipe 3 is threaded into the first annular mounting groove 4, thus initially installing the connecting pipe 3. The connecting pipe 3 connects the air intake pipe 8 and the air intake channel 2. The position of the fixing plate 6 is adjusted by rotating the annular rotating plate 5. After moving the fixing plate 6 to the designated installation position, the fixing plate 6 is locked and fixed to the generator body 1 using the first fastening component, thus fixing the connecting pipe 3. The installation position of the air intake pipe 8 is determined using the second annular mounting groove 10, and the annular mounting plate 11 is then installed. The threaded part is turned into the second annular mounting groove 10 to initially install the air intake pipe 8. The airtightness of the connection between the air intake pipe 8 and the connecting pipe 3 is ensured by the sealing component. The mounting sleeve 12 is rotated to the appropriate position and the mounting sleeve 12 is locked and fixed to the connecting pipe 3 by the second fastening component, thereby fastening the air intake pipe 8 to one end of the connecting pipe 3. Air is introduced into the connecting pipe 3 through the air intake pipe 8. The air is filtered and impurities are removed by the filter layer 7 in the connecting pipe 3. The filtered air is introduced into the air intake channel 2 through the connecting pipe 3, thereby isolating the air impurities entering the generator and allowing for quick replacement of the filter structure.

However, the present invention is not limited to the above embodiments. Within the scope of knowledge possessed by those skilled in the art, various changes can be made without departing from the spirit of the present invention.
