[0032] In the embodiment, Figure 2 、 Figure 3 、 Figure 6 and Figure 7As shown, the right side of the upper air duct 8 is fixed with an L-shaped plate, and the lower side of the L-shaped plate is provided with a threaded hole corresponding to the positioning screw 12. The right side outer wall of the lower air duct 7 is provided with a vertical protruding plate, and eight threaded holes corresponding to the positioning screw 12 are equidistantly arranged on the vertical protruding plate. During installation, the positioning screw 12 can be first disassembled, and then the upper air duct 8 can be pushed upward on the inside of the top of the lower air duct 7, so that the height of the air inlet pipe 9 can be adjusted until the air inlet pipe 9 is adjusted to the top side of the barbecue grill, and the threaded hole below the right side L-shaped plate of the upper air duct 8 is aligned with one of the threaded holes on the vertical protruding plate on the right side outer wall of the lower air duct 7.

The air guide seat 6 is in communication with the air inlet on the right side of the fan 2. When the device is used to purify the smoke generated during the use of the barbecue grill, the lower air duct 7 is first rotated upward to the vertical state, and then the positioning insert plates 11 on the front and rear sides of the lower air duct 7 are pushed downward to the bottom. At this time, the lower part of the positioning insert plate 11 will be embedded in the vertical grooves on the front and rear sides of the air guide seat 6, so that the lower air duct 7 can be fixed in the vertical state.

[0035] In this embodiment, as shown in Figure 1 and Figure 8As shown, the air inlet pipe 9 is a hollow cylindrical pipe and communicates with the cavity inside the upper air guide pipe 8. A long strip-shaped opening is arranged on the left lower side of the air inlet pipe 9, and a vertical partition plate is arranged in the cavity inside the air inlet pipe 9. When the fan 2 is working, the smoke generated during the use of the barbecue grill is adsorbed through the air guide seat 6, the lower air guide pipe 7, the upper air guide pipe 8 and the air inlet pipe 9.

Therefore, the lower air guide pipe 7 is tightly connected with the air guide seat 6.

[0037] In this embodiment, as shown in Figures 1-4 and Figure 7 , the upper air guide pipe 8 is an L-shaped pipe. The outer wall of the upper air guide pipe 8 tightly abuts against the inner wall of the lower air guide pipe 7 and can slide up and down in the cavity inside the lower air guide pipe 7. After the upper air guide pipe 8 is adjusted up and down, the height of the air inlet pipe 9 can be adjusted, so that the device can be used for barbecue grills of different heights, and the sealing performance of the contact surface between the upper air guide pipe 8 and the lower air guide pipe 7 can be ensured.
