The upper case 32 includes a bottom plate 321 and a protrusion 322 protruding upward from a top surface of the bottom plate 321, and the protrusion 322 is hollow. The top bead 34 extends downwardly from within the protrusion 322 below the bottom plate 321 opposite the upper surface of the base 31. The distance between the lower end surface of the top bead 34 and the upper surface of the base 31 is smaller than the thickness of the folded edge 22 of the oil cup 2, so that the folded edge 22 can be pressed by the top bead 34 after being inserted between the lower end surface of the top bead 34 and the upper surface of the base 31. The elastic member 33 is preferably a spring, and is disposed in the protrusion 322, the protrusion 322 limits the elastic member 33, the lower end of the elastic member 33 abuts against the inside of the top bead 34, and the upper end of the elastic member 33 abuts against the top of the inner side of the protrusion 322, so that the top bead 34 keeps a tendency of being exposed downward to the bottom plate 321.

Torsion spring 3231 may be provided on pivot 323 to maintain the tendency of upper housing 32 to flip upward relative to flap 35. The magnet 36 is provided in the bottom plate 321 of the upper housing 32, and this portion is exposed below the smoke collecting hood 11 in the mounted state and can be attracted to the smoke collecting hood 11, so that the upper housing 32 maintains a tendency to turn upward with respect to the flap 35. The bottom plate 321 of the upper casing 32 can be flush with the bottom surface of the fume collecting hood 11 by the action of the magnet 36 or the torsion spring 3231 on the rotating shaft 323.

The lower end surface of the top bead 34 is a revolution surface, and referring to fig. 4 again, a notch or a hole 221 is formed on the folded edge 22 of the oil cup 2 and can be matched with the lower end surface of the top bead 34.

When the oil cup 2 is installed, the oil cup 2 is installed by being pushed forwards and backwards, the rear side of the folded edge 22 of the oil cup 2 firstly props against the lower end face of the top bead 34, the elastic piece 33 is compressed, and the top bead 34 is jacked up; the oil cup 2 continues to be pushed, when the notch 221 (or the hole 221) in the folding edge 22 reaches the position of the top bead 34, the top bead 34 moves downwards, the lower end of the top bead is embedded into the notch 221 (or the hole 221), the oil cup 2 is limited through the notch 221 (or the hole 221), obvious force feedback can be provided, the installation resistance is uniform, and the assembly is completed. The contact area between the revolution surface of the top bead 34 and the oil cup 2 is large, so that the pressure can be effectively reduced, and the oil cup 2 is prevented from being worn due to paint falling and the like caused by friction force. By providing the roller 342, the sliding friction can be converted into rolling friction, thereby further reducing the friction force against the top ball 34 when the oil 2 is filled in.

When the folded edge 22 on one end of the oil cup 2 is accidentally pulled out of the corresponding oil cup mounting assembly 3, referring to fig. 8 and 9, under the gravity of the oil cup 2, the oil cup 2 swings downwards to pry the oil cup mounting assembly 3, and the oil cup mounting assembly 3 swings along with the oil cup 2 against the attraction force of the magnet 36 and the smoke collecting hood 11 (or the elastic force of the torsion spring 3231), namely, the upper shell 32 rotates relative to the folded edge 35, so that the oil cup mounting assembly 3 or the folded edge 22 of the oil cup 2 can be prevented from being pried.

In this embodiment, the oil cup 2 and the oil cup mounting component 3 are protected by rotating the oil cup mounting component 3, so that the oil cup is prevented from being damaged due to one side falling off. The line contact of the roller 342 reduces the pressure on the oil cup 2, and the sliding friction is converted into rolling friction, reducing the abrasion.
