DETAILED DESCRIPTION

[0018] The technical solutions in the embodiments will be described clearly and completely below with reference to the drawings.

[0019] The embodiment of the utility model Figure 1 exhibits a table type remote local exhaust device with jet flow enhancement, which includes a circulation channel, the circulation channel includes an air inlet end, an air outlet end, a circulation structure, a hinge 3 and a pipeline, the air outlet end is provided with a plurality of and selectively used through the circulation structure, the activated carbon-high efficiency composite filter screen 12 is arranged inside the circulation channel and used for cleaning the suction airflow, the volute-air supply duct 14 is sleeved with the plastic bottom shell 10 on the outside, and the centrifugal fan 13 is fixedly installed on the inner bottom of the plastic bottom shell 10 and used for the circulation channel air suction, specifically, please refer to Figure 1 and Figure 2The air inlet includes an exhaust port 2, and the air outlet includes a jet port 1, a jet regulating port 5, and an exhaust duct 11. The circulation structure includes a volute-supply duct 14, with a plastic bottom shell 10 fitted around the outside of the volute-supply duct 14. A rotating disk 6 is provided on one side of the plastic bottom shell 10. The jet regulating port 5 is rotatably connected to the rotating disk 6. Airflow is drawn in through the exhaust port 2, filtered by the volute-supply duct 14, and then enters the exhaust duct 11. It is then selectively discharged through the jet port 1 or the jet regulating port 5. That is, air is drawn into the equipment through the exhaust port 2, passes through the pipe, the corrugated pipe 4, and the exhaust duct 11, and then enters the cavity of the exhaust duct 11 and the activated carbon-high efficiency composite filter 12. After being filtered by the activated carbon-high efficiency composite filter 12, it is input into the interior of the volute-supply duct 14. Since the volute-supply duct 14 has a volute-shaped structure, it has two cavities for containing gas. Figure 2 The inner housing cavity is used for air intake, and the outer housing cavity is used for air exhaust. The outer housing cavity is connected to the exhaust duct 11. Therefore, unclean intake gas and clean output gas can share the exhaust duct 11. Since the jet port 1 and the exhaust port 2 are both connected to one end of the pipe and are set on the same side, the jet adjustment port 5 is connected to the other end of the pipe, the corrugated pipe 4 is embedded in the inside of the pipe and is used for pipe adjustment, and the outside of the pipe is provided with a corrugated pipe 4 for support after pipe adjustment, the output gas can be selectively output from the side-connected jet adjustment port 5 after passing through the exhaust duct 11, or ejected from the jet port 1 after passing through the pipe and the corrugated pipe 4.

Figure 1 The jet regulating ports 5 are arranged in a ring array, and the size of the jet regulating ports 5 is significantly smaller than that of the jet port 1. Therefore, the jet gas can be output smoothly through the jet regulating ports 5 and rapidly through the jet port 1. In use, the jet output follows the principle that "clean air is delivered through the volute-air supply duct 14, some air is discharged through the jet regulating ports 5 to meet specific air supply requirements, and the remaining air is output through the jet port 1 to form a strong jet and improve the exhaust effect."
