The right deflecting plate 4 is symmetrical to the left deflecting plate 3, and the right deflecting plate 4 is vertically erected and fixed in the accommodating space 27 with respect to the right side plate 24, and the right deflecting plate 4 is The front end abuts against the left side surface of the right side plate 24 such that a second angle 02 is formed between the right deflecting plate/the right side plate 24, and the angle of the second refreshing angle 02 is open toward the rear plate 26. Thereby, as shown in Figures 4 and 5, when the object or facility on the work surface 22 generates a heating device g of a temperature fume, for example, a heating furnace or a heating plate, the buoyancy of the warm oil fume by the high temperature gas. The action can be made to raise the soot. When the air extracting device 215 is running, the air is sucked up/by the smoke port 212 and the outside air in front of the operating cabinet 2 is passed through the opening 251 below the front end of the suction hood 21 to perform the air supply. The left deflecting plate 3 and the right deflecting plate 4 are used to guide the airflow to form a stable vortex paired with each other as shown in Fig. 4, and the exhaust port 212 which is stable to the soot is discharged outward. Wherein 'the airflow flows on the right side of the left side panel 23 of the operation cabinet 2 and the left side of the right side panel 24', because of the blocking and guiding of the left and right deflecting plates (3, 4), the inside of the operating cabinet 2 can be accessed. The air will not flow back along the original opening 251 to avoid the high temperature fumes leaking outward. Referring to Figures 6 and 7, it is a second embodiment of the venting apparatus 1 having a deflecting plate, which is different from the first embodiment in that a front side of the front end of the operating pivot 2 is further provided. The plate 25 is formed below the front plate 25, and the first guiding portion 252 is a semicircular horizontal bar formed on the inner side of the bottom of the front plate 25.

In addition, the front side of the bottom plate 22 of the operation cabinet 2 is provided with an elongated air blowing end 221, and a first air supply space 2 2 2 is formed between the left end of the elongated air blowing end 221 and the left side plate 23, and the narrow air blowing end is formed. A second plenum space 223 is formed between the right end of the 2 21 and the right side plate 24, and the elongated blowing end 221 is formed with an elongated blowing port 224 which is parallel to the elongated suction port 212. Further, the elongated blowing end 221 is in communication with a blower 225 to allow the blowing port 224 to blow a two-dimensional air jet vertically upward through the action of the blower 225. In practice, the air blowing port 224 may also blow a two-dimensional air jet upward in the direction of the rear plate 26 of the operating cabinet 2; the air blower 225 may also be mechanically replaced by a cross flow fan or other fluid. [0022] Thereby, as shown in FIGS. 8 to 10, when the air extracting device 215 and the air blower 225 are operated in synchronization, the air jet is ejected upward from the air blowing port 224, and the air jet is taken in by the air extracting port 212 to allow the air to pass. When the first air supply space 222 and the second air supply space 223 are used for air supply, and the left deflecting plate 3 and the right deflecting plate 4 are used to guide the air flow, the elongated air blowing port 224 and the elongated air suction port can be made. A nearly two-dimensional oblique air curtain 8 is formed between the 212, and the contaminants enclosed between the oblique air curtain 8, the rear plate 26 of the operation cabinet 2, and the left and right side plates (23, 24) are stabilized by airflow. It is brought into the upper suction hood and discharged outward through the wind collecting box 214.
