The switch cover 211 and the post plate 206 are installed through the second fixing holes 216.

[0051] When the switch cover 211 is installed on the switch assembly 20, the second limiting buckle 212 is inserted into the second limiting slot 213, and then the switch cover 211 is pushed upward so that the switch cover 211 is stuck in the second limiting notch 214, the switch cover 211 is limited, and then the switch cover 211 is fixed by the second fixing hole 216 in combination with the screw. When removing the switch cover 211, the screws are loosened, and the switch cover 211 is pushed downward so that the second limiting buckle 212 is disengaged from the second limiting slot 213 to complete the disassembly.

[0052] One end of the push rod structure 50 is connected to a rotating piece 501, and the smoke guide plate 30 is provided with a connecting portion 301. The connecting portion 301 and the rotating piece 501 are provided with connecting holes 302 correspondingly.

[0055] The baffle structure 40 is used to shield the internal space of the machine head 10. A hinge 401 is installed between the baffle structure 40 and the machine head 10. The baffle structure 40 is flipped over by the hinge 401 and is arranged on the front side of the machine head 10. The flipping of the baffle structure 40 is achieved by the setting of the hinge 401. When the baffle structure 40 is flipped over, the internal space of the machine head 10 is exposed, thereby facilitating the maintenance of parts in the machine head 10. The machine head 10 is detachably installed with a fixed support plate 103, and the fixed support plate 103 is correspondingly arranged on the inner side of the baffle structure 40. The inner side wall of the baffle structure 40 is provided with a latch buckle 402, and the fixed support plate 103 is provided with a ball buckle 403 corresponding to the latch buckle 402. When the baffle structure 40 is flipped over and closed, the latch buckle 402 is inserted into the ball buckle 403 for matching and limiting, thereby achieving the matching and fixation of the baffle structure 40 and the fixed support plate 103.

[0056] During actual use, when the baffle structure 40 is flipped upward and closed relative to the front side of the machine head 10, the pin buckle 402 fixed to the inner wall of the baffle structure 40 is inserted into the corresponding ball buckle 403 on the fixed support plate 103 to achieve the coordination and fixation of the baffle structure 40 and the fixed support plate 103; the baffle structure 40 is pulled hard to make the pin buckle 402 disengage from the ball buckle 403, thereby achieving the coordination and unlocking of the baffle structure 40 and the fixed support plate 103.

[0057] Through the design of the baffle structure 40, the internal space of the head 10 is shielded. When the internal structure of the range hood needs to be repaired, the user can flip the baffle structure 40 downward to expose the fixed support plate 103, and then remove the fixed support plate 103 to repair the internal structure of the range hood, which is simple and convenient.

[0058] A placement frame 104 is installed in the fixed support plate 103, and an oil collecting box 105 is installed in the placement frame 104. The oil collecting box 105 is used to collect oil stains. By building the oil collecting box 105 into the machine head 10, the oil collecting box 105 is prevented from being exposed to the air, thereby reducing the pollution to the stove panel and not easily attracting insects. The structure is simple and novel, the design is reasonable and compact, and it is practical.

[0059] In this embodiment, an avoidance groove 106 is formed on the fixed support plate 103 at a position close to the bottom of the machine head 10 and corresponding to the hinge 401. The avoidance groove 106 is used for the passage of the hinge 401. By providing the avoidance groove 106, the hinge 401 can be connected to the inside of the machine head 10 at one end and to the inner wall of the baffle structure 40 outside the fixed support plate 103 at the other end, so that the baffle structure 40 will not be affected by the fixed support plate 103 when it is flipped open and closed relative to the front side of the machine head 10 through the hinge 401.

[0060] When the control switch of the utility model needs to be inspected and repaired, the push rod structure 50 is first driven by the push rod motor 502 to move, so that the smoke guide plate 30 is flipped open. After the smoke guide plate 30 is opened, the screws connecting the smoke guide plate 30 and the rotating plate 501 are unscrewed, so that the smoke guide plate 30 is removed to expose the internal mesh plate structure 60, and then the screws connecting the mesh plate structure 60 and the machine head 10 are unscrewed, so as to remove the mesh plate structure 60. After the mesh plate structure 60 is removed, the screws in the first fixing hole 205 of the switch assembly 20 are screwed in. Unscrew and push the switch assembly 20 downward to disengage the first limit buckle 202 from the first limit slot 102, thereby disassembling the switch assembly 20. After the switch assembly 20 is removed, unscrew the screw in the second fixing hole 216 and push the switch cover 211 downward to disengage the second limit buckle 212 from the second limit slot 213, thereby removing the switch cover 211. After the switch cover 211 is removed, unscrew the screw of the switch pressure plate 207 and remove the control switch, thereby realizing the inspection and maintenance of the control switch.
