Abstract

The invention discloses an oil fume purification device. The oil fume purification device comprises a housing, a main fan and a booster fan, wherein the housing is provided with a fume suction port, afume exhaust port and an air duct; the air duct is provided with an air inlet section connected with the fume suction port and an air outlet section connected with the fume exhaust port; the main fanis arranged on the air outlet section; the booster fan is arranged on the air inlet section; and the booster fan is a cross-flow fan. According to the technical scheme, the air pressure of the oil fume purification device can be improved.

Description

technical field [0001] The invention relates to the field of household appliances, in particular to an oil fume purification device. Background technique [0002] The exhaust air flow of the oil fume purification device in use mainly depends on the wind pressure of the fan system of the oil fume purification device. The greater the wind pressure, the greater the exhaust air flow. When ordinary household oil fume purification devices are in use, the oil fume needs to be discharged through resistance devices such as smoke exhaust pipes, check valves, and smoke exhaust channels. The existence of these resistance devices makes the oil fume have a certain back pressure at the oil fume outlet. The existence of back pressure will greatly affect the exhaust flow of the range hood. The wind pressure of the fan system has a positive effect on the exhaust air flow of the oil fume purification device, and the existence of back pressure has a negative effect on the exhaust air flow of t...
