Problems solved by technology
If you blindly increase the power of the range hood fan, although the increase in suction is reflected at the suction port, the increased suction is minimal at a distance from the suction port, that is, in the entire space where the oil fume is generated. The power of the range hood fan has little effect on improving the suction rate of the range hood, but the power consumption and noise have increased significantly.

Embodiment Construction
[0015] The present invention will be further described below in conjunction with the accompanying drawings.
[0016] In the figure, when the gas cooker 2 is in use, smoke is generated, and the motor 3 is turned on to drive the blower 4 to work to generate a positive pressure air flow through the air duct 5, and the induced air outlet 6 is aligned with the oil suction port of the range hood 1 to induce the smoke, so as to achieve improved The effect of range hood on the absorption rate of oil fume.

An oil soot stream guide unit for the oil soot extractor is composed of power cord, control switch, motor, fan and wind pipe. It features that an inducing outlet of oil soot is made on the positive-pressure segment of wind pipe and a wind curtain sprayed upward can prevent escape of oil soot.
Description
technical field [0001] The invention relates to an airflow inducer, in particular to an airflow inducer for range hoods and oil fumes. Background technique [0002] The range hood has become an indispensable household appliance to keep the kitchen clean. How to save energy and improve the absorption rate of oil fume is a very meaningful and influential work. At present, the methods adopted to improve the absorption rate of oil fume One of the most commonly used measures is to increase the power of the range hood fan. According to the principle of aerodynamics, the airflow velocity flowing through the range fume outlet is inversely proportional to the square of the distance between the source of the fume and the range fume outlet; that is to say, the suction force of the range fume outlet will attenuate extremely quickly as the distance increases. If you blindly increase the power of the range hood fan, although the increase in suction is reflected at the suction port, the i...
