In some embodiments of the present invention, the second position-limiting portion 32 includes a fixing portion 321 and a sliding portion 322, the sliding portion 322 can be conveniently installed on the range hood 100 through the fixing portion 321, the sliding portion 322 can slide between the extended position and the retracted position relative to the fixing portion 321, and the sliding portion 322 is often extended, and after the rack assembly 2 is installed in place, the first position-limiting portion 31 is supported on the sliding portion 322. That is, the sliding portion 322 has an extended position and a retracted position, and when the rack assembly 2 is mounted in place, the sliding portion 322 is in the extended position, the first position-limiting portion 31 is supported on the sliding portion 322, and the sliding portion 322 can limit the relative position of the first position-limiting portion 31, so as to mount the rack assembly 2 in the first cavity 11. When the sliding portion 322 is in the retracted position, the first position-limiting portion 31 and the second position-limiting portion 32 may lose their position-limiting relationship with each other, and the rack assembly 2 may be taken out of the first cavity 11.

Optionally, as shown in fig. 3 to 10, a first inclined surface 311 is formed on the first position-limiting portion 31, and a second inclined surface 3221 is disposed on the sliding portion 322, when the frame assembly 2 moves from the bottom to the top through the bottom opening of the first cavity 11, the first inclined surface 311 cooperates with the second inclined surface 3221 and can push the sliding portion 322 to move from the extended position to the retracted position. For example, as shown in fig. 8 and 9, during the process of matching the frame assembly 2 with the first cavity 11, the first inclined surface 311 of the first position-limiting part 31 and the second inclined surface 3221 of the sliding part 322 may be matched with each other, by the mutual engagement between the first inclined surface 311 of the first position-limiting portion 31 and the second inclined surface 3221 on the sliding portion 322, the movement between the first stopper portion 31 and the sliding portion 322 can be stabilized, and further, during the process of the frame assembly 2 being matched with the first cavity 11, through the matching of the first inclined surface 311 and the second inclined surface 3221, the slider 322 can be caused to move from the extended position toward the retracted position, as shown in figure 10, when the first inclined surface 311 slides out of the second inclined surface 3221, the sliding part 322 may move from the retracted position toward the extended position, so that the first stopper portion 31 is supported on the slide portion 322 to mount the housing assembly 2 in the first cavity 11.

Further, the second position-limiting portion 32 further includes an elastic member 323, and the elastic member 323 is disposed between the fixing portion 321 and the sliding portion 322 to enable the sliding portion 322 to extend out. Thus, during the installation of the frame assembly 2, the first position-limiting portion 31 may drive the sliding portion 322 to press the elastic member 323, so that the sliding portion 322 moves from the extended position toward the retracted position, and after the first inclined surface 311 is out of contact with the second inclined surface 3221, the elastic member 323 releases energy to drive the sliding portion 322 to move from the retracted position toward the extended position. Alternatively, the elastic member 323 may be a spring, a sponge member or a rubber member, which is not limited herein.
