When the combination of technical solutions is contradictory or cannot be implemented, it should be deemed that such a combination of technical solutions does not exist and is not within the scope of protection required by the present invention.

[0028] In order to further understand the content, features and effects of the present invention, the following embodiments are given as examples and described in detail with reference to the accompanying drawings:

[0029] The utility model discloses a range hood, such as Figures 1 to 3 As shown, the range hood includes a range hood body 1, a telescopic panel assembly 2, a baffle assembly 3 and functional devices; the range hood body 1 has a top plate 11 and a telescopic inner cavity located above the top plate 11; the telescopic panel assembly 2 is slidably connected in the telescopic inner cavity, and the telescopic panel assembly 2 has an installation cavity; the baffle assembly 3 is slidably connected in the telescopic inner cavity, and when the baffle assembly 3 is located in the telescopic inner cavity, its first end faces outward and its second end faces inward; the functional devices are arranged in the installation cavity; wherein, when the range hood is started, the telescopic panel assembly 2 extends out of the telescopic inner cavity, the functional devices extend out of the telescopic inner cavity along with the telescopic panel assembly 2, the baffle assembly 3 moves out of the telescopic inner cavity along with the telescopic panel assembly 2, and its first end is located below the second end; when the range hood is turned off, the telescopic panel assembly 2 retracts into the telescopic inner cavity, and the baffle assembly 3 is retracted into the telescopic inner cavity along with the telescopic panel assembly 2.

[0030] In this embodiment, the range hood body 1 further includes an air collection box assembly 12 located on the top panel 11 and an air intake 111 connected to the smoke collection chamber of the air collection box assembly 12. The air intake 111 is provided on the top panel 11, at the rear end of the top panel 11, relatively close to the wall, and vertically located diagonally above the stovetop gas outlet. A smoke exhaust fan is installed within the smoke collection chamber. When the smoke exhaust fan is in operation, it creates a negative pressure at the air intake 111. Cooking fumes are drawn into the smoke collection chamber through the air intake 111 and are ultimately exhausted by the smoke exhaust fan.

[0031] When the range hood is turned on, the functional components extend out of the telescopic cavity along with the telescopic panel assembly 2. Once operational, these components can assist the range hood's fume extraction with other functions, such as providing lighting and creating an air curtain. When the range hood is turned off, the functional components cease operation and retract into the telescopic cavity along with the telescopic panel assembly, minimizing the space occupied by the functional components when idle and providing a concealed and protected surface.

[0032] Before the range hood is activated, the first end of the baffle assembly 3 is located in front of the second end, and the baffle assembly 3 is positioned horizontally above the top panel 11. When the range hood is activated, the baffle assembly 3 extends out of the telescopic cavity along with the telescopic panel assembly 2. It is understood that the first end of the baffle assembly 3 extends out of the telescopic cavity before the second end. After extending out of the telescopic cavity, at least a portion of the baffle assembly 3 hangs downward relative to the top panel 11, so that the first end is located below the second end and the top panel 11. Oil fumes generated by the user's cooking are drawn toward the air intake 111 under the negative pressure of the air intake 111. Some of the oil fumes that strike the top panel 11 flow forward along the top panel 11 to the front end of the range hood body 1. Because the first end of the baffle assembly 3 is located below the top panel 11, this portion of the oil fumes are blocked by the hanging portion of the baffle assembly 3. The blocked oil fumes can then flow downward along the baffle assembly 3 before being drawn back toward the air intake 111, thereby reducing oil fume escape and improving the performance of the range hood. When the range hood is turned off, the baffle assembly 3 retracts into the telescopic inner cavity along with the telescopic panel assembly 2, thereby reducing the space occupied by the kitchen.

[0033] In the smoke machine of the present invention, Figure 3 and Figure 4 As shown, the baffle assembly 3 includes a baffle 31 and a rotating connector 32. The rotating connector 32 connects the second end of the baffle 31 to the lower surface of the telescopic panel assembly 2. The baffle 31 is rotatably connected to the rotating connector 32. When the telescopic panel assembly 2 extends out of the telescopic cavity, at least the portion of the rotating connector 32 connected to the second end of the baffle 31 extends out of the telescopic cavity, and the baffle 31 flips downward. The rotating connector 32 includes a first connecting portion and a second connecting portion that are hingedly connected to each other. The first connecting portion is connected to the lower surface of the telescopic panel assembly 2, and the second connecting portion is connected to the second end of the baffle 31. The second connecting portion can flip up and down relative to the first connecting portion, allowing the baffle 31 to switch between a horizontal position and a drooping position.

[0034] Because the rotating connector 32 is connected to the lower surface of the telescopic panel assembly 2, when the telescopic panel assembly 2 moves forward, it will also drive the rotating connector 32 and the baffle 31 to move forward together. After the telescopic panel assembly 2 is extended out of the telescopic cavity and the functional components are fully extended out of the telescopic cavity, the baffle 31, the second connecting portion, and the hinged joint between the first and second connecting portions should also be located outside the telescopic cavity. This allows the baffle 31 and the second connecting portion to lose the support of the top plate 11, allowing the baffle 31 and the second connecting portion to flip downward under the action of gravity, thereby achieving natural drooping of the baffle 31 after extending out of the telescopic cavity.

[0035] When the telescopic panel assembly 2 retracts into the telescopic inner cavity, it will also drive the rotating connection 32 and the baffle 31 to move backward together. In the process of the baffle assembly 3 retracting into the telescopic inner cavity, the first connection part retracts into the telescopic inner cavity first, and then the hinge between the first connection part and the second connection part retracts into the telescopic inner cavity. Immediately afterwards, the baffle 31 and the second connection part flip upward under the abutment of the front edge of the top plate 11, so that the baffle assembly 3 returns to the horizontal state and enters the telescopic inner cavity.

[0036] In the smoke machine of the present invention, Figure 3 and Figure 4 As shown, the baffle assembly 3 also includes a connecting plate 33, which is connected to the lower surface of the telescopic panel assembly 2. A rotating connector 32 connects the second end of the baffle 31 and the connecting plate 33. The upper surface of the connecting plate 33 is connected to the lower surface of the telescopic panel assembly 2, and the second connecting portion of the rotating connector 32 is connected to the lower surface of the connecting plate 33. The hinge between the first and second connecting portions is located on the front side of the connecting plate 33. The thickness of the hinge between the first and second connecting portions is greater than that of the second connecting portion. If the second connecting portion is directly connected to the telescopic panel assembly 2, it will be obstructed by the hinge between the first and second connecting portions, affecting the stability of the connection. The connecting plate 33 separates the lower surface of the telescopic panel assembly 2 from the hinge between the first and second connecting portions. Since the hinge between the first and second connecting portions is located on the front side of the connecting plate 33, it does not hinder the connection process between the second connecting portion and the connecting plate 33. In this way, the connection area between the second connection portion and the connection plate 33 and the connection area between the connection plate 33 and the telescopic panel assembly 2 can be guaranteed, thereby improving the connection strength between the second connection portion and the telescopic panel assembly 2.

[0037] In the smoke machine of the present invention, Figure 3 As shown, the distance between the lower surface of the telescopic panel assembly 2 and the bottom surface of the telescopic inner cavity is adapted to the thickness of the baffle 31 and the connecting plate 33. When the telescopic panel assembly 2 extends out of the telescopic inner cavity, the connecting plate 33 moves to the exit of the telescopic inner cavity. A first spacing is formed between the lower surface of the telescopic panel assembly 2 and the bottom surface of the telescopic inner cavity. The first spacing is greater than or equal to the thickness of the baffle 31 and the connecting plate 33, so that the connecting plate 33 and the baffle 31 can be smoothly accommodated in the space below the telescopic panel assembly 2. When the telescopic panel assembly 2 extends out of the telescopic inner cavity, the connecting plate 33 moves to the exit of the telescopic inner cavity, so that the baffle 31 and the rotating connector 32 can be completely located outside the telescopic inner cavity, avoiding the front end of the top plate 11 from obstructing the drooping process of the baffle 31, resulting in incomplete drooping of the baffle 31, thereby ensuring the effect of the baffle 31 in blocking the escape of oil smoke.

[0038] In the smoke machine of the present invention, Figure 2As shown, the width from the first end to the second end of the baffle 31 is no greater than the length of the portion of the baffle 31 located in front of the telescopic panel assembly 2 when the telescopic panel assembly 2 extends out of the telescopic inner cavity. When both the telescopic panel assembly 2 and the baffle 31 extend out of the telescopic inner cavity and the baffle 31 is drooping, a second spacing is formed between the front end of the telescopic panel assembly 2 and the drooping baffle 31. This second spacing is greater than the width from the first end to the second end of the baffle 31. In this way, when the baffle 31 returns to its horizontal position and retracts into the telescopic inner cavity, the first end of the baffle 31 does not protrude beyond the front end of the telescopic panel assembly 2. This ensures that when the front end of the telescopic panel assembly 2 reaches the opening of the telescopic inner cavity, the baffle 31 has fully entered the telescopic inner cavity, further enhancing the concealment and protection of the baffle 31 when it is idle.

[0039] In the range hood of the present invention, when the telescopic panel assembly 2 extends out of the telescopic inner cavity, the functional components are located outside the baffle assembly 3. When both the telescopic panel assembly 2 and the baffle 31 extend out of the telescopic inner cavity and the baffle 31 is drooping, the functional components are located in front of the drooping baffle 31, thereby preventing the baffle 31 from interfering with the operation of the functional components and ensuring their effective operation.

[0040] In the range hood of the present invention, the functional devices include an air curtain assembly and / or a lighting assembly and / or an air quality detection assembly. An air curtain inlet hole 21 and / or a detection hole 22 is provided on the top plate 11 of the installation cavity, and an air curtain outlet hole 23 and / or a lighting window is provided on the bottom plate of the installation cavity. When the telescopic panel assembly 2 extends out of the telescopic inner cavity, the part of the top plate 11 of the installation cavity with the air curtain inlet hole 21 and / or the detection hole 22 extends out of the telescopic inner cavity, and the part of the bottom plate of the installation cavity with the air curtain outlet hole 23 and / or the lighting window extends to the front side of the baffle assembly 3.

[0041] In the illustrated embodiment, the functional components include an air curtain assembly, a lighting assembly, and an air quality detection module. The top plate 11 of the mounting cavity is provided with an air curtain inlet 21 and a detection hole 22, while the bottom plate is provided with an air curtain outlet 23 and a lighting window. When the telescopic panel assembly 2 is extended from the telescopic inner cavity, the portion of the top plate 11 of the mounting cavity with the air curtain inlet 21 and the detection hole 22 extends out of the telescopic inner cavity, while the portion of the bottom plate of the mounting cavity with the air curtain outlet 23 and the lighting window extends to the front of the baffle assembly 3. When the range hood is started, the telescopic panel assembly 2 is fully extended from the telescopic inner cavity. The air curtain inlet 21 and the detection hole 22 corresponding to the air curtain assembly on the top wall of the telescopic panel assembly 2 and corresponding to the air quality detection module move out to the front of the telescopic baffle assembly 3. The air curtain outlet 23 corresponding to the air curtain assembly and the lighting window corresponding to the lighting assembly on the bottom plate of the telescopic panel assembly 2 move out to the front of the baffle assembly 3. At this point, the lighting assembly among these functional components can be activated to provide illumination, allowing the user to clearly see the status of cooking ingredients. When the smoke exhaust fan is started and the air intake 111 is opened, the air curtain assembly is started and forms an air curtain between the user and the stove to prevent the escape of oil smoke; when the range hood is running, the air quality detection module detects the air quality above the top plate of the range hood in real time to determine the smoke purification effect of the range hood.

[0042] In the smoke machine of the present invention, Figure 5 and Figure 6 As shown, the range hood also includes a drive assembly 4, which is located above the top plate 11. The drive assembly 4 is connected to the telescopic panel assembly 2 and is used to drive the telescopic panel assembly 2 to extend or retract into the telescopic cavity. When the range hood is started, the control unit controls the drive assembly 4 to operate, thereby promptly driving the telescopic panel assembly 2 to extend out of the telescopic cavity and driving the baffle assembly 3 to move out of the telescopic cavity. When the range hood is turned off, the control unit controls the drive assembly 4 to operate in the opposite direction, thereby promptly driving the telescopic panel assembly 2 to retract into the telescopic cavity and driving the baffle assembly 3 to retract into the telescopic cavity. In this way, the telescopic panel assembly 2 and the baffle assembly 3 can be automatically driven, thereby improving the convenience of using the range hood.

[0043] In the smoke machine of the present invention, Figure 5 and Figure 6As shown, the drive assembly 4 includes a reduction motor 41, a gear 42 and a rack 43. The output end of the reduction motor 41 is connected to the gear 42, and the rack 43 is connected to the telescopic panel assembly 2. The gear 42 is connected to the rack 43. The reduction motor 41 refers to an integrated body of a reducer and a motor. The output speed of the reduction motor 41 can be adjusted according to actual needs. By controlling the output speed of the reduction motor 41, the moving speed of the telescopic panel assembly 2 can be controlled. The gear 42 can rotate with the output end of the reduction motor 41. The gear 42 is engaged with the rack 43, and the rotation of the output end of the reduction motor 41 can be converted into the linear motion of the rack 43, so that the rack 43 drives the telescopic panel assembly 2 to perform linear motion. For example, when the output end of the reduction motor 41 rotates forward, it can drive the telescopic panel assembly 2 to move forward and extend out of the telescopic inner cavity. When the output end of the reduction motor 41 is reversed, it can drive the telescopic panel assembly 2 to retract into the telescopic inner cavity.

[0044] According to one embodiment of the present invention, Figure 1 and Figure 5 As shown, the range hood body 1 also includes an oil cup 5 and an oil dripping hole 112 connected to the smoke collecting chamber of the air collecting box assembly 12. The oil cup 5 is used to receive the oil dripping through the oil dripping hole 112. The oil dripping hole 112 is provided on the top plate 11. The oil cup 5 is mounted below the top plate 11 and has a receiving chamber that opens upward. The downward projection of the oil dripping hole 112 is always located within the opening of the receiving chamber of the oil cup 5. During the process of exhausting oil fumes from the range hood, the mixture of oil and water in the oil fumes forms oil liquid that accumulates in the smoke collecting chamber and on the volute of the exhaust fan. The oil liquid eventually flows through the oil dripping hole 112 to the oil cup 5 to achieve oil collection.

[0045] The above are only preferred embodiments of the present invention and are not intended to limit the present invention. Any modifications, equivalent replacements or improvements made within the spirit and principles of the present invention should be included in the scope of protection of the present invention.
