[0027] To further understand the content, features, and effects of this utility model, the following embodiments are provided, and detailed descriptions are given below in conjunction with the accompanying drawings:

[0028] This utility model discloses a smoke hood. Please refer to [link / reference]. Figures 1 to 3 The range hood proposed in this utility model includes a housing 1 and a panel module. The housing 1 has a front plate 11, a side plate 12, a bottom plate 13, a cover plate 14 and a back plate 15. The back plate 15 is connected to the corresponding parts of the side plate 12, the bottom plate 13 and the cover plate 14. The front plate 11 is connected to the side plate 12 and the cover plate 14. The lower part of the front plate 11 is provided with a notch. The panel module is located in the notch and is adapted to the notch. The panel module includes an upper panel assembly 2 and a lower panel assembly 3. The upper panel assembly 2 is connected to the front plate 11 and is located in the notch. The lower panel assembly 3 is rotatably connected to the bottom plate 13 and is located in the notch. When the upper edge of the lower panel assembly 3 is far away from the lower edge of the upper panel assembly 2, the gap between the lower panel assembly 3 and the edge of the notch and the lower edge of the upper panel assembly 2 forms an air inlet.

[0029] In this embodiment, the front plate 11, side plate 12, bottom plate 13, cover plate 14, and back plate 15 form a smoke collection chamber, and the air inlet communicates with the smoke collection chamber. The range hood also includes an exhaust assembly and an exhaust box. The exhaust box is installed on the top of the housing 1 and communicates with the smoke collection chamber. The exhaust assembly is installed inside the exhaust box, and an exhaust port is provided on the top of the exhaust box. The exhaust assembly is used to provide the power required for the range hood to extract oil fumes. After the exhaust assembly is started, it will generate negative pressure in the smoke collection chamber, which will drive the airflow. The oil fumes in the kitchen will be drawn into the smoke collection chamber from the air inlet, and then flow further to the exhaust box before being discharged from the exhaust port.

[0030] A notch is made in the front panel 11, and the panel module is installed in the notch. The shape and size of the panel module are adapted to the shape and size of the notch. The upper panel assembly 2 is fixedly connected to the front panel 11, and the lower panel assembly 3 is rotatably connected to the bottom plate 13. The lower panel assembly 3 can rotate relative to the upper panel assembly 2. When the upper edge of the lower panel assembly 3 is far away from the lower edge of the upper panel assembly 2, the gap between the lower panel assembly 3 and the edge of the notch and the lower edge of the upper panel assembly 2 forms an air inlet. When the upper edge of the lower panel assembly 3 is close to the lower edge of the upper panel assembly 2, the air inlet is closed.

[0031] The panel module is installed within the notch of the front panel 11. The lower panel assembly 3 can rotate relative to the upper panel assembly 2. When the upper edge of the lower panel assembly 3 moves away from the lower edge of the upper panel assembly 2, the gap between the lower panel assembly 3, the edge of the notch, and the lower edge of the upper panel assembly 2 forms an air inlet. The panel module and the front panel 11 can be made of different materials, and the lower panel assembly 3 and the upper panel assembly 2 forming the air inlet can also be made of different materials, thus making the appearance and function of the range hood's panel more diverse. The lower panel assembly 3 can be rotated to open or close the air inlet, thereby improving the performance of the range hood.

[0032] The smoke hood of this utility model, such as Figures 3 to 4 As shown, a drive module 4 is provided inside the smoke collection chamber. The drive end of the drive module 4 is connected to the lower panel assembly 3. When the drive module 4 is started, the upper edge of the lower panel assembly 3 flips into the smoke collection chamber.

[0033] The drive module 4 can drive the lower panel assembly 3 to rotate, so as to realize the automatic rotation of the lower panel assembly 3. When the drive module 4 drives the upper edge of the lower panel assembly 3 to flip into the smoke collection chamber, the gap between the lower panel assembly 3 and the edge of the notch and the lower edge of the upper panel assembly 2 forms an air inlet; when the drive module 4 drives the lower panel assembly 3 to reset, the upper edge of the lower panel assembly 3 approaches the lower edge of the upper panel assembly 2, and the air inlet is closed.

[0034] The smoke hood of this utility model, such as Figures 5 to 6 As shown, a connecting portion 111 extends from the lower edge of the front panel 11 into the notch, and the upper panel assembly 2 is connected to the connecting portion 111. The connecting portion 111 simplifies the connection between the upper panel assembly 2 and the front panel 11, thereby improving the ease of installation of the upper panel assembly 2.

[0035] The smoke hood of this utility model, such as Figures 5 to 6 As shown, the part of the side panel 12 corresponding to the notch extends to the plane of the front panel 11 with an extension surface 121. The edge of the extension surface 121 extends to the back panel 15 with a baffle plate 122. When the lower panel assembly 3 rotates and forms an air inlet in the notch, the baffle plate 122 protrudes from both sides of the air inlet.

[0036] There are two baffles 122, which are located on both sides of the notch. When the lower panel assembly 3 is flipped into the smoke collection chamber to open the air inlet, the baffles 122 block the smoke collection chamber on both sides of the air inlet, preventing the user's line of sight from directly seeing the inside of the smoke collection chamber between the two sides of the lower panel assembly 3 and the two sides of the notch. This can block the smoke collection chamber, improve the user's viewing experience, and prevent external debris from easily entering the smoke collection chamber.

[0037] The smoke hood of this utility model, such as Figure 6 As shown, the range hood also includes a reinforcing plate 16, which is located between the baffle plate 122 and the side plate 12. The side plate 12 has a first connecting surface 123 that connects to the back plate 15. The front and rear sides of the reinforcing plate 16 are respectively provided with a second connecting surface 161 and a third connecting surface 162. The second connecting surface 161 connects to the front plate 11, and the third connecting surface 162 connects to the first connecting surface 123.

[0038] The reinforcing plate 16 can improve the structural strength of the shell 1 at the side plate 12. The first connecting surface 123 is connected to the third connecting surface 162, which can realize the connection between the reinforcing plate 16 and the side plate 12 and the back plate 15. The second connecting surface 161 is connected to the front plate 11, which can realize the connection between the reinforcing plate 16 and the front plate 11. In this way, the front plate 11, the side plate 12, the back plate 15 and the reinforcing plate 16 can be connected to form a whole, thereby improving the overall structural stability of the shell 1.

[0039] The smoke hood of this utility model, such as Figures 4 to 6 As shown, a reinforcing part 131 extends from the front edge of the base plate 13. The reinforcing part 131 is inclined backward from bottom to top, and the upper end of the reinforcing part 131 is connected to the back plate 15.

[0040] When the lower panel assembly 3 rotates to open the air inlet, the distance between the lower panel assembly 3 and the notch gradually decreases from top to bottom. The reinforcing part 131 is located on the rotation path of the lower panel assembly 3. The reinforcing part 131 can limit the rotation of the lower panel assembly 3 to its limit position, preventing the lower panel assembly 3 from rotating excessively away from the notch. The distance between the reinforcing part 131 and the notch gradually decreases from top to bottom, thereby adapting to the distance between the lower panel assembly 3 and the notch when it rotates to its limit position. This increases the contact area between the lower panel assembly 3 and the reinforcing part 131 at the limit position, improving the contact and limiting stability of the reinforcing part 131 on the lower panel assembly 3. The upper end of the reinforcing part 131 is connected to the back plate 15, so that the force from the lower panel assembly 3 on the reinforcing part 131 can be partially transferred to the back plate 15, thereby improving the limiting support stability of the reinforcing part 131 and preventing the reinforcing part 131 from deforming or being damaged due to independent force.

[0041] The smoke hood of this utility model, such as Figure 6 As shown, the edge of the portion of the baffle plate 122 corresponding to the reinforcing part 131 is provided with a support surface 124. The inclination angle of the support surface 124 is adapted to the reinforcing part 131, and the two sides of the reinforcing part 131 are connected to the support surface 124. The support surface 124 is located below the reinforcing part 131 and can provide auxiliary support for the reinforcing part 131 to improve the support stability of the reinforcing plate 16 and prevent the reinforcing part 131 from being easily deformed or damaged due to frequent impacts from the lower panel assembly 3.

[0042] The smoke hood of this utility model, such as Figures 3 to 4 As shown, the lower panel assembly 3 is connected to the base plate 13 via a hinge 31. The reinforcing part 131 has a clearance opening. One piece of the hinge 31 is connected to the lower panel assembly 3, and the other piece of the hinge 31 passes through the clearance opening and is connected to the base plate 13. Rotating the lower panel assembly 3 to the base plate 13 via the hinge 31 simplifies the rotational connection between them. The hinge 31 has a simpler structure and occupies less space, thus reducing the size of the clearance opening and ensuring the connection strength between the reinforcing part 131 and the base plate 13.

[0043] The smoke hood of this utility model, such as Figure 6 As shown, a sealing element 32 is provided on the inner side of the upper edge of the lower panel assembly 3. The sealing element 32 extends upward beyond the upper edge of the lower panel assembly. After the lower panel assembly 3 is inserted into the notch, the sealing element 32 abuts against the rear wall of the upper panel assembly 2.

[0044] The seal 32 can be made of rubber or sponge. When the lower panel assembly 3 is rotated to close the air inlet, the seal 32 can seal the gap between the upper edge of the lower panel assembly 3 and the lower edge of the upper panel assembly 2, preventing external debris or insects from easily entering the smoke collection chamber and affecting the internal structure of the range hood. In addition, when the range hood is turned off, when the oil accumulated on the front panel 11 and the upper panel assembly 2 flows downward to the gap between the upper edge of the lower panel assembly 3 and the lower edge of the upper panel assembly 2, the seal 32 can prevent the oil from flowing into the gap, thus preventing oil overflow and ensuring that the range hood has a clean and tidy appearance.

[0045] The smoke hood of this utility model, such as Figure 3 As shown, the drive module 4 includes a drive component 41, a first connecting rod 42, and a second connecting rod 43. The drive component 41 is mounted on the front panel 11 and located inside the smoke collection chamber. The output end of the drive component 41 is connected to the input end of the first connecting rod 42, the output end of the first connecting rod 42 is connected to the input end of the second connecting rod 43, and the output end of the second connecting rod 43 is connected to the lower panel assembly 3.

[0046] The drive unit 41 can be a motor. The output end of the drive unit 41 is connected to one end of the first connecting rod 42, and the other end of the first connecting rod 42 is connected to one end of the second connecting rod 43. The other end of the second connecting rod 43 is connected to the lower panel assembly 3. The drive unit 41 can drive the first connecting rod 42 to rotate, causing the first connecting rod 42 to drive the second connecting rod 43 to swing, thereby allowing the second connecting rod 43 to move the lower panel assembly 3. In this way, the automatic rotation of the lower panel assembly 3 can be achieved through the drive unit 41, the first connecting rod 42, and the second connecting rod 43, thereby improving the automation effect of the range hood.

[0047] The above are merely preferred embodiments of the present utility model and are not intended to limit the present utility model. Any modifications, equivalent substitutions or improvements made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
