[0028] It can be understood that by setting up the smoking component 1, the distance between the smoking port 11 and the work station to be exhausted is shortened, and the setting of the booster fan 2 is used to increase the air pressure between the smoking component 1 and the exhaust branch pipe 10, improve the exhaust effect, and thus more pipes can be added to meet the increasing production capacity requirements.

[0029] In some embodiments, the smoking component 1 includes a tee 12 and a smoking hose 13; the smoking port 11 is located on the tee 12, and each smoking port 11 is connected to a smoking hose 13.

[0031] In some embodiments, the cross-sectional area of the air inlet hood 23 gradually increases along the air inlet direction, and the cross-sectional area of the air outlet hood 24 gradually decreases along the air outlet direction. The structural settings of the air inlet hood 23 and the air outlet hood 24 can further increase the air inlet pressure of the exhaust hose, and thus improve the exhaust effect.

[0032] In some embodiments, the cross-section of the side of the air inlet hood 23 connected to the fan body 22 is rectangular to expand the adsorption area of the air inlet hood 23. Specifically, the cross-section of the side of the air outlet hood 24 connected to the fan body 22 is also rectangular.
