An oil outlet 12 is arranged at the bottom of the oil cup assembly 1 or the lower end of the outer side wall and is in communication with the oil collecting groove 11. The oil outlet 12 is in communication with a sewer or a special drain groove through an oil guide pipe 10, so that the medium (such as oil stains or cleaning water) in the oil cup assembly can be discharged in time through the oil guide pipe 10. In addition, a clamping part 13 is arranged at the upper end of the left and right side walls of the oil cup assembly 1, respectively. The clamping part 13 is used for cooperating with a hook in the extractor hood to be clamped, so that the oil cup device can be stably and reliably detachably installed at the bottom of the main body of the extractor hood.

[0032] The oil cup device further comprises a switch assembly 2 and a heating assembly 3. The switch assembly 2 is arranged on the oil cup assembly 1 and is used for opening or closing the oil outlet 12, so as to automatically control whether the oil cup assembly automatically discharges oil. The heating assembly 3 is arranged on the oil cup assembly 1 and is used for heating the medium in the oil collecting groove 11.

[0033] When the oil stains solidify in the oil collecting groove 11 of the oil cup assembly 1 and reach a certain amount, the heating assembly 3 is started to heat and melt the solid oil stains in the oil collecting groove 11. When the temperature of the oil stains reaches a set temperature, the solid oil stains in the oil cup assembly 1 melt into liquid. At this time, the switch assembly 2 is used to open the oil outlet 12, so that the liquid oil stains in the oil cup assembly can be automatically discharged through the oil outlet and the oil guide pipe 10 in turn. When the oil stains are discharged, the switch assembly 2 is used to close the oil outlet 12. Before, during or after the switch assembly 2 opens the oil outlet, the heating assembly is closed to stop heating. As can be seen, without dismounting the oil cup assembly 1, the purposes of automatically discharging oil stains and simply cleaning the oil cup assembly 1 can be achieved.

[0034] Specifically, the bottom surface of the oil collecting groove 11 is arranged in a manner that one end is high and the other end is low. The oil outlet 12 is arranged at the low end of the bottom surface of the oil collecting groove 11 at the bottom of the oil cup assembly 1, so that the oil stains in the oil collecting groove 11 can automatically flow to the oil outlet 12. In addition, an annular inclined surface 111 is arranged around the oil outlet 12 on the bottom surface of the oil collecting groove 11.
