[0046] The existing oil cup hanging ear is mainly installed at the bottom of the range hood. In order to increase the aesthetics, the upper part of the oil cup hanging ear is designed to be stored inside the range hood, while the lower part of the oil cup hanging ear (including the hanging ear groove) is exposed to the outside of the range hood. The oil cup is inserted into the hanging ear groove to realize the installation of the oil cup and the range hood, so as to collect the oil generated during the operation of the range hood.

[0047] However, during use, the oil inside the range hood will flow into the interior of the oil cup hanger through the gap on the top of the oil cup hanger, soaking the spring inside the oil cup hanger, reducing the elastic force of the spring, causing the internal spring to have poor expansion and contraction effect, or even failure.

[0048] Example 1
