[0030] The present invention will be further described in detail below with reference to the accompanying drawings and embodiments.

[0031] like Figure 1 and Figure 2 As shown, the range hood in this embodiment includes a body 1, a connecting assembly 10, and an oil cup 2 located at the lower end of the body 1. The oil cup is detachably mounted on the body 1 via the connecting assembly 10. In this embodiment, there are two sets of connecting assemblies 10, which are respectively arranged at both ends of the oil cup 2 along its length.

[0032] Combination Figure 3 , Figure 4 andFigure 5 As shown, each connecting assembly 10 includes a connecting block 4, a connecting seat 3, a guide ring 6, a guide rod 7, and a reset component 8. The connecting block 4 is located inside the body 1 and has a longitudinal inner cavity 41 and a transverse inner cavity 42 intersecting the longitudinal inner cavity 41.

[0033] The connecting seat 3 is mounted on the oil cup 2 and has a guide head 5 at its upper end that can extend into the longitudinal inner cavity 41 of the connecting block 4. The end of the guide head 5 forms an enlarged limiting part 51. The lower end of the limiting part 51 is concave upward to form an annular groove 52. The top of the limiting part 51 is flat, and the side is spherical. This facilitates alignment with the longitudinal inner cavity and makes installation more convenient.

[0034] In this embodiment, the guide head 5 and the connecting seat 3 are integrally formed. The connecting seat 3 is fixed to the inner wall of the oil cup 2 as an insert. It has the advantages of high strength, not easy to deform, and no dead corner surface treatment to prevent leakage. At the same time, it is easy for users to clean.

[0035] The guide ring 6 is fitted onto the guide head 5 and can move up and down. The limiting part 51 can restrict the guide ring 6 from detaching from the guide head 5. The lower end face of the guide ring 6 has an inverted first conical surface 61. The upper end face of the guide ring 6 has a second conical surface 62 adapted to the annular groove 52.

[0036] The guide rod 7 is movably disposed in the transverse inner cavity 42 of the connecting block 4. The front end of the guide rod 7 can extend into the longitudinal inner cavity 41 of the connecting block 4 and has an inclined surface 71 that cooperates with the limiting part 51 and the first conical surface 61.

[0037] The reset element 8 constantly forces the guide rod 7 to maintain a forward extension tendency; in this embodiment, the reset element 8 is a spring sleeved on the outside of the guide rod 7, with one end of the spring abutting against the inner wall of the transverse inner cavity 42 and the other end abutting against the protrusion 72 of the guide rod 7. Through the spring and structural limiting, there is feedback during installation and removal, which is highly perceptible to the user.

[0038] like Figure 5 As shown, with the oil cup 2 positioned in the body 1, the front end of the guide rod 7 extends into the longitudinal inner cavity 41 and abuts against the bottom of the limiting part 51 for limitation; as Figures 6-9 As shown, with the oil cup 2 detached from the body 1, the front end of the guide rod 7 gradually moves backward in conjunction with the first conical surface 61 of the guide ring 6.

[0039] Specifically, when installing the oil cup, the user places the oil cup under the machine body, with the back of the oil cup against the wall. Pressing the oil cup upwards, the guide head contacts the longitudinal inner cavity of the connecting seat, slides upwards to contact the inclined surface of the guide rod and compresses the spring, until it slides past the guide rod and stops. At this point, the oil cup is properly installed. Figure 5 As shown.

[0040] Combination Figures 6-9As shown, when removing the oil cup: the user operates as above, continuing to press the oil cup upwards. At this time, the guide ring slides upwards to contact the inclined surface of the guide rod, compressing the spring in the first half and returning the spring to its original position in the second half. Then, the oil cup can be removed downwards, and the spring will automatically compress accordingly.
