The connector 223 penetrates the base 221 and the flexible tube 222 from bottom to top, and the upper end of the connector 223 is connected to the smaller end (upper end) of the flexible tube 222 by means of glue or the like. Providing the flexible tube 222 with a truncated cone shape may facilitate passage from the inside to through the other end when pulling one end of the flexible tube 222.

The connector 223 includes a hollow connecting seat 2231 and a connecting body 2232 disposed on the connecting seat 2231, wherein the connecting seat 2231 is located in the base 221, and the connecting body 2232 is located in the flexible tube 222. The inner side wall of the connecting seat 2231 is provided with an internal thread 2233, and the bottom thereof may be flush with the bottom of the base 221. The upper end of the connecting body 2232 is connected to the smaller sized end of the flexible tube 222.

The base 221 has a first side groove 2211 formed in a circumferential wall thereof, the first side groove 2211 penetrates through the inner side and the outer side of the circumferential wall of the base 221, and the first side groove 2211 extends for a certain distance along the circumferential direction of the base 221. The circumferential wall of the base 221 is further opened with a second side slot 2212, and the second side slot 2212 penetrates through the inner side and the outer side of the circumferential wall of the base 221, and also penetrates through the bottom surface of the base 221.

A level detection device may be provided in the oil cup 21 to alert the user to clean up in time when a warning line is exceeded (which is no higher than the flexible tube 222).

Referring to fig. 7 to 10, when the oil in the oil cup 21 needs to be cleaned, it is collected by a waste oil collecting container 100 (a waste beverage bottle or a mineral water bottle). The mouth of the waste oil collection container 100 has external threads 101 and, in use, the mouth of the waste oil collection container 100 is aligned with the connector 223 and the internal threads 2233 of the connector 223 mate with the external threads 101 of the mouth. When the waste oil collecting container 100 is screwed in, the upper surfaces of the convex claws 2234 of the connector 223 are in contact with the upper surfaces of the first side grooves 2211 of the base 221, so that the first side grooves 2211 of the base 221 limit the convex claws 2234 of the connector 223, and the connector 223 cannot always rotate along with the waste oil collecting container 100 in the screwing-in process, so that the waste oil collecting container 100 can be smoothly screwed in the connector 223. After the waste oil collecting container 100 is screwed in, the connector 223 is driven to rotate together in the opposite direction, the convex claw 2234 of the connector 223 rotates in the opposite direction to be aligned with the second side groove 2212 of the base 221, the connector 223 moves out of the base 221 in the downward direction, the connector 223 drives the smaller end of the flexible pipe 222 to deform and move downward together, when the height of the flexible pipe 222 is lowered below the waste oil level, the waste oil flows into the waste oil collecting container 100 through the connector 223 along the flexible pipe 222, and the height of the flexible pipe 222 can be lowered below the inner bottom surface of the oil cup 21 (the position of the step part 212). After the waste oil in the oil cup 21 is collected, the claw 2234 of the connector 223 aligns with the second side groove 2212 of the base 221, moves upward, contacts the upper surface of the first side groove 2211 of the base 221, and rotates the waste oil collecting container 100 along the screwing-out direction, after the waste oil collecting container 100 is completely screwed out, the connector 223 can be clamped in the first side groove 2211 of the base 221, and the flexible pipe 222 obtains a certain height again, so that the waste oil cannot flow out of the oil cup. The waste oil collecting container 100 with the collected waste oil is screwed on a bottle cap and can be placed at a position capable of recycling garbage or waste oil, so that the waste oil of the range hood can be recycled.

With the oil collecting structure, the user only needs to screw the waste oil collecting container 100 into the connector 223 when discharging oil, and does not need to wait all the time, and the user can do other things during the period and can take down the waste oil after discharging the oil. In the oil extraction process, the waste oil in the waste oil collecting container 100 is increased, the downward pulling force generated on the oil cup 21 is increased, the downward bending degree in the middle of the oil cup 21 is increased due to the increase of the pulling force, the waste oil is concentrated in the middle of the oil cup 21, and the waste oil is discharged and drained. The oil discharge device 22 is designed to be convenient and quick to collect oil by the waste oil collecting container 100, and is inconvenient or even difficult to operate when other vessels are used for collecting oil, so that the design is favorable for people to change the habit of dumping waste oil before, and the habit of recovering waste oil is favorable for people.
