Referring to fig. 5, 6 and 11, the movable teeth 35 have two teeth, which are respectively disposed at both sides of the hook main body 331, can be engaged with the hook main body 331 near the hook main body 331 so that the hook assembly 3 and the hanger 2 are relatively fixed, and can be disengaged from the hook main body 331 far from the hook main body 331 so that the hook assembly 3 can be adjusted in height with respect to the hanger 2. In this embodiment, the movable tooth 35 is accommodated between the two mounting posts 344 on the same side of the hook main body 331, so as to limit the position of the movable tooth 35 in the longitudinal direction. The movable tooth 35 is provided with a second tooth 351 on a side toward the hook main body 331, the second tooth 351 being for meshing with the first tooth 332 of the hook 33. A limiting groove 352 is formed in one side, away from the hook 33, of each movable tooth 35, one end of the pressure spring 36 is located in the limiting groove 352, and the other end of the pressure spring abuts against a wall surface corresponding to the adjusting groove 341 of the housing 34.

If the adjusting knob 32 is moved back and forth, the adjusting knob is inserted between the two movable teeth 35 when moving backward, so as to move the movable teeth 35 away from the hook main body 331.

Referring to fig. 14, the first teeth 332 are inclined teeth, and the bottom surfaces of the first teeth 332 are gradually inclined downward from a side close to the hook main body 331 toward a direction away from the hook main body 331. The second teeth 351 are rectangular teeth, so that the two teeth can only move in one direction when being meshed. I.e. the movable tooth 35 can move upwards relative to the hook 33 but cannot move downwards. The tooth space between two adjacent first teeth 332 is d1, the thickness (the size in the longitudinal direction) of the second tooth 351 is d2, and d1 is more than 1.2d2, so that the second tooth 351 can be ensured to be better inserted between two adjacent first teeth 332 of the hook 33, and the locking strength is ensured.

Referring again to fig. 5, a bottom plate 37 is provided at the bottom of the hook 33 below the housing 34, the bottom plate 37 being larger than the perforation 342 to prevent the housing 34 from falling off the hook 33 during adjustment.

Therefore, when the range hood is installed, the hook 33 of the hook component 3 is firstly pushed to the uppermost position relative to the shell 34, at the moment, the bottom plate 37 plays a limiting role, and the sliding block 323 of the adjusting knob 32 is in a state of long axis transverse and short axis longitudinal; then, the hook 334 of the hook 33 is hung in the hanging hole 23 of the hanger 2, at this time, the first mounting hole 222 on the hanger 2 is aligned with the second mounting hole 3311 on the hook 33, and the hook 33 is fixedly connected with the hanger 2 by the anti-dropping screw 4 passing through the first mounting hole 222 and the second mounting hole 3311, so as to prevent the range hood from falling off when the range hood is lifted; meanwhile, the adjusting knob 32 is rotated by 90 degrees, so that the sliding block 323 of the adjusting knob 32 is in a state that the short axis is transverse and the long axis is longitudinal, that is, two ends of the sliding block 323 cannot apply force to the movable teeth 35, and the movable teeth 35 are engaged with the hooks 33 under the action of the pressure spring 36 to be in a one-way locking state, as shown in fig. 4 and 5.

When the mounting height of the range hood needs to be adjusted, the hook 33 and the movable teeth 35 are only in a one-way locking state at the moment, and the range hood is pushed upwards to enable the movable teeth 35 to be upward relative to the hook 33, so that the height of the range hood can be conveniently adjusted. Due to the one-way locking function of the hook component 3, the clearance between the range hood and the cabinet can be eliminated.

When the range hood needs to be disassembled, the adjusting knob 32 only needs to be rotated by 90 degrees, at this time, two ends of the long shaft of the sliding block 323 are respectively embedded into the positioning notches 354 of the corresponding movable teeth 35, the sliding block 323 extrudes the movable teeth 35 towards the direction far away from the hook 33, so that the movable teeth 35 and the hook 33 are separated, the one-way locking state is released, see fig. 12 and 13, and then the anti-falling screw 4 is disassembled.
