[0044] Example 1

[0045] The range hood head is easy to maintain, and the front side of the head 1 is connected to a flip-over baffle structure 13, such as Figure 1 , Figure 2 As shown;

[0046] After the baffle structure 13 is turned upside down and opened and closed at the front side of the machine head 1, an opening 17 can be exposed at the front side of the machine head 1. Fig.11 As shown;

[0047] The opening 17 is used to expose the inner space of the head 1 for maintenance.

[0048] In this embodiment, the baffle structure 13 is a condensation glass plate.

[0049] In this embodiment, the inner wall of the baffle structure 13 is connected with a hinge 15, such as Figure 5 As shown;

[0050] The other end of the hinge 15 is connected to the inside of the machine head 1; the baffle structure 13 is flipped up and down on the front side of the machine head 1 through the hinge 15;

[0051] In this embodiment, the baffle structure 13 is flipped relative to the front side of the machine head 1 by flipping up and down with its bottom side as the axis.

[0052] A fixing plate 2 is detachably connected to the opening 17 at the front side of the machine head 1. The fixing plate 2 corresponds to the inner side of the baffle structure 13. Figure 3 As shown;

[0053] That is, after the baffle structure 13 is flipped downward, the fixing plate 2 is first exposed, and after the fixing plate 2 is removed, the opening 17 is exposed at the front side of the machine head 1 .

[0054] The fixed plate 2 includes a limiting assembly. When the baffle structure 13 is turned upward and closed relative to the machine head 1, the inner side wall of the baffle structure 13 can be fixed with the fixed plate 2 through the limiting assembly.

[0055] In this embodiment, the limiting assembly includes a ball buckle 22 and a latch structure 14;

[0056] The ball buckle 22 is installed on the fixing plate 2. Figure 3 , Figure 7 As shown;

[0057] The latch structure 14 is fixedly connected to the inner side wall of the baffle structure 13, and one end of the latch structure 14 can be inserted into the ball buckle 22 to achieve positioning. Figure 5 , Figure 6 As shown;

[0058] During actual use, when the baffle structure 13 is flipped upward and closed relative to the front side of the machine head 1, the pin structure 14 fixed to the inner wall of the baffle structure 13 can be inserted into the corresponding ball buckle 22 on the fixed plate 2 to achieve the coordination and fixation of the baffle structure 13 and the fixed plate 2; the user pulls the baffle structure 13 hard to make the pin structure 14 disengage from the ball buckle 22, thereby achieving the coordination and unlocking of the baffle structure 13 and the fixed plate 2.

[0059] In this embodiment, the fixing plate 2 is close to the bottom of the machine head 1, and a position corresponding to the hinge 15 is formed with an avoidance groove 23 for the hinge 15 to pass through. Figure 3 , Figure 7 As shown;

[0060] By setting the avoidance groove 23, the hinge 15 can be connected to the inside of the head 1 at one end and to the inner wall of the baffle structure 13 outside the fixed plate 2 at the other end, so that the baffle structure 13 will not be affected by the fixed plate 2 when it is flipped open and closed relative to the front side of the head 1 through the hinge 15.

[0061] In this embodiment, a plurality of first mounting holes 24 are formed through the surface of the fixing plate 2, and the fixing plate 2 is fixed by screws passing through the first mounting holes 24 and tightening with the corresponding screw holes in the machine head 1; by unscrewing the screws passing through the first mounting holes 24, the fixing plate 2 can be separated from the machine head 1.

[0062] When the internal structure of the range hood head needs to be repaired, the user can flip down the baffle structure 13 to expose the fixing plate 2, and then unscrew the screws on the surface of the fixing plate 2 that pass through the first mounting hole 24, and remove the fixing plate 2 from the front side of the head 1, thereby exposing the opening 17. After the opening 17 is exposed, the internal structure of the head 1 can be repaired through the opening 17, thereby achieving the effect of being able to conveniently repair the internal structure of the head 1 without removing the range hood from the wall.

[0063] The front side of the machine head 1 includes a smoke guide plate 12, which corresponds to the upper side of the baffle structure 13. Figure 1 , Figure 2 As shown;

[0064] The head 1 is provided with a mesh plate 16, which corresponds to the inner side of the smoke guide plate 12. Figure 3 , Figure 4 As shown;

[0065] In this embodiment, the fixing plate 2 is an oil receiving box fixing plate, and the oil receiving box fixing plate is connected to the oil receiving box 21. Figure 7 As shown;

[0066] The oil receiving box 21 corresponds to the bottom of the mesh plate 16. Figure 8 As shown;

[0067] The mesh plate 16 can filter the grease in the oil smoke, and the grease can flow into the oil receiving box 21 to be collected.

[0068] The front side of the head 1 includes an operation panel 11, which is used to control the operation of the range hood head;

[0069] The operation panel 11 is correspondingly arranged above the smoke guide plate 12. Figure 1 , Figure 2 shown.

[0070] The smoke guide plate 12 can be turned upside down and opened and closed relative to the front side of the machine head 1 with its side close to the operation panel 11 as the axis;

[0071] When the range hood head is in use, the smoke guide plate 12 needs to be flipped upwards and opened to expose the mesh plate 16 inside. The attracted smoke will enter the head 1 through the mesh plate 16 under the guidance of the smoke guide plate 12; when the range hood is not in use, the smoke guide plate 12 is flipped downwards and closed, which can cover the mesh plate 16, increase the overall aesthetics of the head 1, and protect the mesh plate 16.

[0072] Furthermore, the smoke guide plate 12 is connected to a push rod structure 3, and the push rod structure 3 is used to control the flipping of the smoke guide plate 12;

[0073] In this embodiment, the push rod structure 3 is arranged inside the head 1. Figure 3 , Figure 4 As shown;

[0074] One end of the push rod structure 3 is connected to a rotating piece 31, and the inner side wall of the smoke guide plate 12 is connected to the rotating piece 31. Fig. 9 As shown;

[0075] The push rod structure 3 is controlled and connected to the rotating plate 31, such as Fig.10As shown, the upward and downward extension of the push rod structure 3 can drive the rotating piece 31 to swing forward and backward, thereby achieving the purpose of influencing the smoke guide plate 12 to flip open and close;

[0076] In this embodiment, only one side of the machine head 1 is provided with a push rod structure 3, which is connected to one side of the smoke guide plate 12 through a rotating plate 31. The push rod structure 3 is used to actively control the flipping and opening of the smoke guide plate 12; the other side of the smoke guide plate 12 is drivenly connected to the machine head 1 through the rotating plate 31. Fig. 9 shown.

[0077] The push rod structure 3 is connected to a push rod motor 35. Fig. 9 , Fig.10 As shown;

[0078] The push rod motor 35 is used to control the operation of the push rod structure 3, so as to realize the electrically driven operation of the smoke guide plate 12 to flip and open relative to the machine head 1;

[0079] The push rod motor 35 is connected to the control module in the head 1. When the range hood is turned on or off, the push rod motor 35 can rotate clockwise or counterclockwise accordingly, thereby controlling the extension and retraction of the push rod structure 3, so that the smoke guide plate 12 automatically flips open or automatically flips closed when the range hood is turned on or off.

[0080] The push rod structure 3 is located on one side of the inner mesh plate 16 of the machine head 1. A maintenance cover plate 4 is detachably provided on the front side of the push rod structure 3. When the smoke guide plate 12 is flipped upward and opened, the user can remove the maintenance cover plate 4 to repair the push rod structure 3.

[0081] Furthermore, the maintenance cover plate 4 includes a card structure 41, and the card structure 41 is formed on the upper and lower sides of the maintenance cover plate 4. Figure 3 As shown;

[0082] A card slot is formed between the operation panel 11 and the machine head 1 at a position corresponding to the card structure 41;

[0083] A card slot is formed between the fixing plate 2 and the machine head 1 at a position corresponding to the card structure 41;

[0084] A second mounting hole 42 is provided on the side of the maintenance cover 4. Figure 3 , Fig.11 As shown;

[0085] The maintenance cover plate 4 is used to cover the outer side of the push rod structure 3 . When the push rod structure 3 fails and needs to be repaired, the push rod structure 3 can be repaired by removing the maintenance cover plate 4 .

[0086] When installing the maintenance cover 4, it is necessary to first insert the card structure 41 on the top into the card gap between the operation panel 11 and the machine head 1, and then tighten it with the screw hole of the machine head 1 through the second mounting hole 42; then connect the fixing plate 2 to the machine head 1 to form a card gap between the fixing plate 2 and the machine head 1, and surround the card structure 41 at the bottom of the maintenance cover 4 through the card gap; in this way, the card structures 41 at the upper and lower ends of the maintenance cover 4 are respectively located in the upper and lower card gaps, which further improves the connection stability between the maintenance cover 4 and the machine head 1.

[0087] In this embodiment, the push rod motor 35 is located at a position corresponding to the opening 17 in the head 1. Fig.11 As shown; the push rod motor 35 is detachably connected to the machine head 1;

[0088] The significance of such design lies in that the smoke guide plate 12 is electrically driven to flip and open under the control of the push rod motor 35. If the push rod motor 35 is located on the inner side of the maintenance cover 4 corresponding to the position of the smoke guide plate 12 in the machine head 1, when the push rod motor 35 fails, the smoke guide plate 12 will not be electrically driven to flip and open upward, so that the maintenance cover 4 located on the side of the mesh plate 16 cannot be exposed, and it is difficult for the user to repair the push rod motor 35; and the push rod motor 35 is positioned corresponding to the opening 17. When the push rod motor 35 fails, the user can flip the baffle structure 13 downward to open it, and then unscrew the screws on the first mounting hole 24 to remove the fixing plate 2 from the front side of the machine head 1 to expose the opening 17. The opening 17 will expose the push rod motor 35, so that the push rod motor 35 can be conveniently repaired; after the opening 17 exposes the push rod motor 35, it will be removed from the machine head 1. After the push rod motor 35 is removed, the smoke guide plate 12 can be manually flipped open to expose the maintenance cover 4, and then the push rod structure 3 can be repaired.

[0089] In this embodiment, the push rod structure 3 includes a push rod bracket 32 ​​and a push rod seat 33. Fig. 9 , Fig.10 As shown, the push rod structure 3 is connected to the inside of the machine head 1 through the push rod bracket 32 ​​and the push rod seat 33;

[0090] The push rod structure 3 is detachably connected to the push rod seat 33 via bolts 34;

[0091] The push rod structure 3 is connected to the push rod bracket 32, and the push rod bracket 32 ​​is detachably connected to the inside of the machine head 1 by screws;

[0092] When the push rod structure 3 needs to be disassembled, the push rod structure 3 can be separated from the machine head 1 by unscrewing the screws that cooperate with the machine head 1 and then unscrewing the bolts 34.

[0093] Example 2

[0094] This embodiment is different from the first embodiment in that, in this embodiment, the baffle structure 13 is preferably, but not limited to, flipped left and right relative to the front side of the machine head 1 with its left or right side as the axis to achieve opening and closing.

[0095] The above are only specific embodiments of the present invention, but the technical features of the present invention are not limited thereto. Any simple changes, equivalent replacements or modifications made based on the present invention to achieve basically the same technical effects are all included in the protection scope of the present invention.
