As the utility model discloses a further optimization scheme, blast apparatus and air current spiral case connected angle, mode, the size of connector, position adopt more reasonable structure.

For the further optimization scheme of the utility model, the size and the shape of the inner wall and the outer wall of the airflow volute, the distance between the two end faces and the gradient of the two end faces are adopted.

As a further optimization scheme of the utility model, blast apparatus and collection petticoat pipe device pendant adopt the mode of dismantling more easily and easy to assemble.

As a further optimization scheme of the utility model, directional mouthful adoption is favorable to forming structure, size, the position of negative pressure air current more.

As a further optimization scheme of the utility model, the position, size, shape, quantity, the direction of advancing the mouth adopt and are favorable to oil smoke exhaust structure, it is equipped with the collection petticoat pipe to advance mouth department.

As a further optimization scheme of the utility model, the exhaust port installation can change the device of the wind direction of discharging fume, preventing that external wind from getting into smoke exhaust passage.

Do the utility model discloses a further optimization scheme, the size, the shape of exhaust port and inlet flue are more rationally matched. The cyclone device is arranged inside the cyclone device.

As a further optimization scheme of the utility model, the quantity of motor and the size of power in the blast apparatus, size, the shape of motor wind wheel.

As a further optimization scheme of the utility model, blast apparatus's shape, motor wind wheel hookup location and connected mode.

As the utility model discloses a further optimization scheme, shape, size, the control interface on the collection petticoat pipe and the position of control interface of collection petticoat pipe.

As the utility model discloses a further optimization scheme, another kind of structure of lampblack absorber is located the extension for the position of advancing the mouth of cigarette and advances cigarette passageway below, advances cigarette passageway and wall parallel, it is equipped with the collection petticoat pipe to advance mouth department.

Compared with the prior art, the novel smoke exhaust device has the advantages that the uniform airflow is formed in the airflow volute by blowing through the blowing device, and is blown to the smoke exhaust channel through the directional port in one direction, so that negative pressure airflow generated in the smoke inlet channel drives oil smoke to be exhausted through the smoke exhaust channel. Because the oil smoke discharges the in-process and can not pass through motor and wind wheel, consequently it can not glue the greasy dirt, has ensured blast apparatus's long-term performance, has improved life. This novel project organization is unobstructed, greatly reduced the noise in the work. The separated structure design is convenient for later cleaning and maintenance.
