When the smoke guide plate 13 is connected to the smoke collecting hood 1, the male lock buckle component 3 can swing relative to the front and rear directions of the smoke collecting hood 1 to increase the activity angle of the male lock buckle component 3. If the smoke guide plate 13 opens the air inlet 11, the smoke guide plate 13 drives the male lock buckle component 3 to rotate through the flipping movement of the smoke guide plate 13, so that the smoke guide plate 13 can be quickly removed from the smoke collecting hood 1. The structure is simple and easy to disassemble and assemble, and the activity angle of the male lock buckle component 3 can be increased, so that the smoke guide plate 13 can be opened at a large angle.

[0031] Furthermore, the male lock buckle assembly 3 includes a base 31, a rotating shaft 32 and a male lock buckle body 33, wherein the base 31 is installed on the top wall of the smoke guide plate 13, one end of the male lock buckle body 33 is hinged to the base 31 through the rotating shaft 32, and the other end passes through the oil net 12 and is connected to the female lock buckle assembly 2 in a matching manner.

[0032] Preferably, a boss 34 is protruding from the base 31, a mounting hole 341 is opened on the boss 34, and the bottom of the male lock body 33 is mounted outside the boss 34 and a through hole 331 is opened at a position corresponding to the mounting hole 341, and the rotating shaft 32 is passed through the mounting hole 341 and the through hole 331 to hinge the male lock body 33 and the base 31 together.

In addition, a baffle 37 is convexly provided on the male lock buckle body 33 along the circumferential direction. When the male lock buckle body 33 passes through the oil net 12 at one end away from the base 31 and is connected to the female lock buckle assembly 2 in a coordinated manner, the top wall of the baffle 37 abuts against the bottom wall of the oil net 12 to limit the flipping movement of the smoke guide plate 13. At the same time, since the male lock buckle body 33 rotates along the front-to-back direction relative to the base 31, the rotation angle of the male lock buckle body 33 in this embodiment is 3° to 6°, which can increase the activity angle of the male lock buckle assembly 3, thereby facilitating the smoke guide plate 13 to open at a large angle. Specifically, the rotation angle of the male lock buckle body 33 can be set to other more suitable angles according to actual needs. Preferably, the mounting frame 35 is welded and fixed on the top wall of the smoke guide plate 13, and the base 31 is installed together with the mounting frame 35 by screws, thereby effectively improving the firmness of the installation between the base 31 and the smoke guide plate 13, thereby facilitating the disassembly and assembly of the male lock buckle assembly 3.

[0040] Particularly, the angle between the smoke guide plate 13 and the horizontal plane is 25° to 26°.

[0041] In this embodiment, since the male lock assembly 3 is symmetrically arranged on both sides of the front end of the smoke hood 1, the female lock assembly 2 is correspondingly arranged on the left and right sides of the smoke hood 1, so that the installation position of the female lock assembly 2 can be arranged on the left and right sides of the air inlet 11 of the smoke hood 1 without affecting the air volume parameters of the range hood, through holes 14 are symmetrically opened on the lower end walls on both sides of the smoke hood 1, and sleeves 23 are respectively arranged on the front and rear ends of the through holes 14. A fixed cavity with one end open is defined in the sleeve 23, and the ball 21 is arranged at the open end of the fixed cavity so that the two sleeves 23 in The ball 21 is arranged correspondingly, one end of the spring 22 abuts against the ball 21, and the other end abuts against the sealing end of the fixed cavity so that the spring 22 limits the movement of the ball 21. A buckle groove 36 is concave inwardly provided on the male lock component 3. The male lock component 3 passes through the oil net 12 and the through hole 14 in sequence so that the buckle groove 36 is clamped by the two balls 21, so that the two balls 21 clamp the buckle groove 36 through the elastic force of the spring 22, and then the male lock component 3 and the female lock component 2 are buckled together. Of course, the male lock component 3 and the female lock component 2 can also be disconnected under the action of external force.
