According to the oil cup assembly 1 and the range hood provided by the embodiment, the up-and-down limiting of the oil cup 11 is realized through the matching of the bearing plate part 131 and the ear hanging plate part 121, and the limiting of the oil cup 11 in the left-and-right direction and the front-and-back direction after being installed can be realized through the arrangement of the first curved surface 12121 and the second curved surface 1321 which can be attached, so that the installation stability of the oil cup 11 in each direction is ensured, and the oil cup 11 is prevented from shaking in the left-and-right direction and the front-and-back direction; meanwhile, the first curved surface 12121 is arranged at the side of the ear hanging plate part 121, and the second curved surface 1321 is arranged at the side of the extension plate part 132, which is perpendicular to the direction of gravity, so that even if the bearing plate part 131 and the ear hanging plate part 121 deform under the action of the gravity of the oil cup 11 and oil, the deformation has a small influence on the matching of the first curved surface 12121 and the second curved surface 1321, thereby effectively ensuring the assembly reliability of the oil cup 11 in the long-term use process, and reducing the risk that the oil cup 11 slides down due to the deformation of the installation component.

In order to simplify the process of mounting the assembly, one of the first curved surface 12121 and the second curved surface 1321 is a convex curved surface and the other is a concave curved surface, thereby enabling to simplify the structure of the first curved surface 12121 and the second curved surface 1321. However, it is understood that in other embodiments, the first curved surface 12121 and the second curved surface 1321 may also be a combination of a convex curved surface and a concave curved surface, such as a wave-shaped curved surface, as long as the first curved surface 12121 and the second curved surface 1321 are matched.

In the present embodiment, the first curved surface 12121 is a concave curved surface, and the second curved surface 1321 is a convex curved surface, so as to reduce the difficulty in processing the second mounting plate portion 133. In other embodiments, the first curved surface 12121 can also be a convex surface and the second curved surface 1321 can be a concave surface.

More preferably, the first curved surface 12121 and the second curved surface 1321 are both arc surfaces to further simplify the structure of the first curved surface 12121 and the second curved surface 1321, and the first curved surface 12121 and the second curved surface 1321 can rotate relatively, so that the other end of the oil cup 11 can rotate around the end of the oil cup 11 with the matching surface of the first curved surface 12121 and the second curved surface 1321 at the end as a fulcrum during the assembling and disassembling process of the oil cup 11, and the two ends of the oil cup 11 do not need to be aligned with the two bearing plate portions 131 for assembling and disassembling synchronously, thereby improving the convenience of assembling and disassembling the oil cup 11, and ensuring the stability during the assembling and disassembling process of the oil cup 11.

The carrier plate portion 131 can be inserted into the lower side of the ear plate portion 121 through the rear opening of the installation gap and attached to the ear plate portion 121, and the extension plate portion 132 can abut against the side of the ear plate portion 121 and can rotate by a set angle in the installation gap, the set angle being smaller than 90 °.

In the process of installing the oil cup 11, one set of installation components is firstly assembled, taking the installation component on the left side as an example: moving the position of the oil cup 11 to make the bearing plate part 131 in the set of mounting assemblies face the mounting gap; moving the oil cup 11 from front to back to insert the bearing plate part 131 between the ear plate part 121 and the end plate 114; thereafter, the oil cup 11 is moved in a direction away from the second fixture 13 (i.e., the oil cup 11 is moved leftward) so that the carrier plate portion 131 is inserted below the hanger plate portion 121, and at this time, the lower surface of the hanger plate portion 121 abuts against the upper surface of the carrier plate portion 131, and the first curved surface 12121 abuts against the second curved surface 1321. Thereafter, the mounting assembly at the other end of the oil cup 11 is mounted: the oil cup 11 is horizontally deflected by taking a matching surface of the first curved surface 12121 and the second curved surface 1321 as a rotation fulcrum, so that the ear plate portion 121 at the other end of the oil cup 11 is rotatably inserted between the bearing plate portion 131 and the bottom surface of the machine body 2 until the first mounting member 12 and the second mounting member 13 are assembled in place.

When the oil cup 11 is disassembled, firstly one group of the mounting components is disassembled: the mating surface of the first curved surface 12121 and the second curved surface 1321 of another set of mounting assemblies is used as a rotation fulcrum, so that one detached end of the oil cup 11 is deflected forward, the bearing plate part 131 is rotated out of the lower side of the ear plate part 121, the tail end of the oil cup 11 is pulled forward, the bearing plate part 131 can be separated from the rear opening of the mounting gap, and the mounting assembly at the other end is detached thereafter.

In the present embodiment, the thicknesses of the ear plate portion 121 and the carrier plate portion 131 are preferably 0.8mm to 2mm, so that the ear plate portion 121 and the carrier plate portion 131 have certain elasticity after being mounted, thereby further improving the convenience of mounting and dismounting the first mounting piece 12 and the second mounting piece 13. More preferably, the thicknesses of the ear plate portions 121 and the carrier plate portions 131 are 1mm to 1.5 mm.

To improve the convenience of mounting and dismounting the oil cup 11, the height of the extension plate portion 132 is greater than the thickness of the ear plate portion 121, that is, when the ear plate portion 121 is inserted between the bearing plate portion 131 and the machine body 2, a gap is formed between the ear plate portion 121 and the machine body 2, so that the insertion of the ear plate portion 121 between the bearing plate portion 131 and the bottom surface of the machine body 2 can be facilitated. Preferably, the height of the extension plate portion 132 is preferably greater than or equal to 2mm and less than or equal to 4mm, so as to ensure that the hanger plate portion 121 is smoothly inserted between the bearing plate portion 131 and the machine body 2, and avoid the problem that the hanger plate portion 121 is easily dropped due to an excessively large gap between the hanger plate portion 121 and the bottom surface of the machine body 2.

The lower surface of the ear plate 121 is preferably inclined downward from front to back, and the upper surface of the bearing plate 131 is inclined downward from front to back, and the inclination angle of the upper surface of the bearing plate 131 is the same as that of the lower surface of the ear plate 121, so that the upper surface of the bearing plate 131 can be attached to the lower surface of the ear plate 121 after the first mounting part 12 and the second mounting part 13 are fitted. By the arrangement, after the hanger plate part 121 and the bearing plate part 131 are assembled, the hanger plate part 121 has a backward inclined acting force relative to the machine body 2, the oil cup 11 is prevented from inclining forwards under the action of gravity, and even if the oil cup 11 has a tendency of inclining successively, the oil cup is kept stable due to the limiting effect of the wall body because the rear side of the oil cup 11 is the wall body, namely, the oil cup 11 stably abuts against the wall body, and the stability of the oil cup 11 after being assembled is further improved.

Further, the inclination angle of the lower surface of the hanger plate portion 121 relative to the horizontal plane is less than 20 °, that is, the inclination angle of the upper surface of the bearing plate portion 131 relative to the horizontal plane is less than 20 °, so as to better ensure the bearing effect of the bearing plate portion 131 on the oil cup 11.

It is to be noted that the foregoing is only illustrative of the preferred embodiments of the present invention and the technical principles employed. It will be understood by those skilled in the art that the present invention is not limited to the particular embodiments described herein, but is capable of various obvious changes, rearrangements and substitutions as will now become apparent to those skilled in the art without departing from the scope of the utility model.
