After the waste oil collecting container 100 is screwed in, the connector 223 is driven to rotate together in the opposite direction, the claw 2234 of the connector 223 rotates to be aligned with the second side groove 2212 of the base 221, the connector 223 moves downwards so that the connector 223 moves out of the base 221, the connector 223 drives the upper end of the telescopic pipe 222 to deform and move downwards together, when the upper end of the telescopic pipe 222 is compressed below the waste oil liquid level in the lower end direction, at the moment, the upper end of the connector 223 also moves below the waste oil liquid level, waste oil flows into the waste oil collecting container 100 along the connector 223, and the height of the telescopic pipe 222 can be lowered below the inner bottom surface of the oil cup 21 (the position of the step 212), at the moment, the telescopic pipe 222 is in a compressed state. When the waste oil in the oil cup 21 is collected, the second side groove 2212 of the pair Ji De of the claw 2234 of the connector 223 moves upward to drive the connector 223, the connector 223 drives the upper end of the telescopic tube 222, and after the connector 223 contacts the upper surface of the first side groove 2211 of the base 221, the waste oil collecting container 100 rotates in the unscrewing direction, and after the waste oil collecting container 100 is completely unscrewed, the connector 223 is clamped in the first side groove 2211 of the base 221, and the telescopic tube 222 regains a certain height, so that the waste oil cannot flow out of the oil cup. The waste oil collecting container 100, which is filled with waste oil after collection, is screwed with a bottle cap and can be placed at a recyclable waste or waste oil recycling place, so that waste oil recycling of the range hood is possible.
In the oil collecting structure, a user only needs to screw the waste oil collecting container 100 into the connector 223 when discharging oil, the user does not need to wait all the time, and the user can do other things during the period, and the user can take off the waste oil after discharging oil. In the process of discharging oil, the downward pulling force generated on the oil cup 21 is increased while the waste oil in the waste oil collecting container 100 is increased, and the degree of downward bending in the middle of the oil cup 21 is increased due to the increase of the pulling force, so that the waste oil is concentrated in the middle of the oil cup 21, and the waste oil is discharged and cleaned. The oil discharging device 22 is designed to be convenient and quick to collect oil by the waste oil collecting container 100, and is inconvenient and even difficult to operate when the waste oil collecting container is used for collecting oil by other vessels, so that the habit of pouring waste oil before is changed by people is improved, and the habit of recovering waste oil by people is improved.
