[0047] Example 1

[0048] like Figure 7 As shown, the smoke pipe 1 provided by the utility model is used to be installed on a table top 4 with a stove in a smoking device. The smoke pipe 1 can be located in the middle of the two stoves, or can be located at the leftmost or rightmost side of the table top 4.

[0049] like Figure 1 - Figure 5 As shown, the smoke duct 1 includes a main pipe 11 and an air inlet structure 12 . The main pipe 11 is provided with an air outlet 111 , the air inlet structure 12 is provided with an air inlet 121 , and an air passage connecting the air inlet 121 and the air outlet 111 is provided inside the smoke duct 1 .

[0050] like Figure 8 As shown, the smoking device includes a guide channel 3 and a fan assembly 2 located in the guide channel 3. The fan assembly 2 is used to generate an airflow from the inlet of the guide channel 3 toward the outlet. The guide channel 3 runs through the table 4 so that its inlet is connected to the smoke outlet, thereby generating an airflow from the smoke inlet to the smoke outlet in the smoke pipe 1.

[0051] The main pipe 11 is rotatably connected to the air inlet structure 12 so that the direction of the air inlet 121 can be adjusted. The user can rotate the air inlet structure 12 according to different cooking scenes to change the direction of the air inlet 121, so that the air inlet 121 can be directed to a location with a higher concentration of oil smoke, reduce oil smoke escape, and improve smoking efficiency.

[0052] The main pipe 11 and the air inlet structure 12 can change the direction of the air inlet 121 by manually pushing and pulling the air inlet structure 12 without the aid of the driving module 13 .

[0053] In this embodiment, the smoke pipe 1 further includes a driving module 13 , and a driving end of the driving module 13 is connected to the air inlet structure 12 for driving the air inlet structure 12 to rotate relative to the main pipe 11 .

[0054] like Figure 3 and Figure 5 As shown, the driving module 13 may include a motor, the main body of the driving module 13 is fixed on the main pipe 11, and the driving end of the driving module 13 is connected to the air inlet structure 12, and the air inlet structure 12 can be rotated relative to the main pipe 11 by pushing, pulling or twisting.

[0055] In this embodiment, the air inlet structure 12 can rotate in the horizontal direction relative to the main pipe 11, that is, the rotation axis of the air inlet structure 12 is arranged in the vertical direction, and the air inlet 121 is oriented to the desired angle by changing the horizontal direction. In another feasible solution, the air inlet structure 12 can also rotate in the vertical direction relative to the main pipe 11, that is, the rotation axis of the air inlet structure 12 is arranged in the horizontal direction, and the air inlet 121 is oriented to the desired angle by changing the pitch angle. In another feasible solution, the air inlet structure 12 is connected to the main pipe 11 through a universal structure, such as a ball head universal joint, so that the direction of the smoke inlet can be changed in a wider range.

[0056] like Figure 5 As shown, a first connection port is provided on the main pipe 11, and the first connection port is connected to the air outlet 111; the air inlet structure 12 includes a swing pipe, and a second connection port is provided on the swing pipe, and the second connection port is connected to the air inlet 121; the first connection port is rotatably connected to the second connection port.

[0057] The air inlet structure 12 includes a swinging tube. The tubular structure can make the air inlet structure 12 closer to the cookware, that is, closer to the smoke source, after rotating.

[0058] It should be noted that the swing tube may be a telescopic tube, such as a multi-stage sleeve structure, and the horizontal distance between the smoke inlet and the smoke source may be adjusted by extending and retracting the swing tube to improve flexibility.

[0059] Of course, the air inlet structure 12 may also include a grille structure instead of a tubular structure, and an air passage is formed between two adjacent grilles. The direction of the smoke inlet can be changed by changing the direction of the grilles.

[0060] Example 2

[0061] like Figure 6 As shown, the difference from Embodiment 1 is that, in this embodiment, a side inlet 112 may be further provided on the circumferential side wall of the main pipe 11, and the side inlet 112 faces one side of the stove and may also absorb oil smoke, thereby increasing the smoking range.

[0062] like Figure 7 - Fig.10 As shown, the smoking device provided by the utility model includes the above-mentioned smoke pipe 1; the smoking device also includes a fan assembly 2, a guide channel 3, a table 4 and the smoke pipe 1; a stove and the smoke pipe 1 are arranged on the upper surface of the table 4; one end of the guide channel 3 passes through the table 4 and is connected to the air outlet 111, and the other end forms a smoke exhaust port, and the fan assembly 2 is arranged in the guide channel 3 for generating an airflow from the air outlet 111 toward the smoke exhaust port.

[0063] In this embodiment, the smoke pipe 1 is located between two stoves. The oil smoke enters from the smoke inlet of the smoke pipe 1, flows into the guide channel 3 from the smoke outlet, and then passes through the fan assembly 2, and finally is discharged from the smoke outlet. The smoke pipe 1 on the table 4 is closer to the stove, that is, closer to the smoke source, and the smoking effect is better.

[0064] The smoking device further comprises a housing, which is located above the table 4. The guide channel 3 extends upward from the bottom of the table 4 to the inside of the housing, and a part of the space inside the housing forms a part of the guide channel 3. The fan assembly 2 is arranged in the housing.

[0065] In an implementable solution, the smoke pipe 1 can be fixed relative to the table top 4, and the table top 4 is provided with an avoidance hole 41 penetrating the upper and lower surfaces thereof, the diameter of the avoidance hole 41 is roughly equal to the diameter of the smoke outlet, and the guide channel 3 can pass through the avoidance hole 41 and connect with the smoke outlet on the table top 4.

[0066] In another feasible solution, the smoke pipe 1 can be fixed relative to the table top 4, and the table top 4 is provided with an avoidance hole 41 penetrating the upper and lower surfaces thereof, and the smoke pipe 1 is arranged in the avoidance hole 41. The inner diameter of the avoidance hole 41 can be slightly larger than the outer diameter of the smoke pipe 1, and the smoke pipe 1 can be inserted into the avoidance hole 41, thereby realizing the connection between the smoke pipe 1 and the table top 4.

[0067] like Figure 7 As shown, in this embodiment, the smoke pipe 1 can be lifted and lowered relative to the table 4, that is, the smoke pipe 1 can pass through the avoidance hole 41. Specifically, the outer diameter of the smoke pipe 1 is greater than the inner diameter of the avoidance hole 41, and the smoking device further includes a first lifting drive mechanism 6, which may include a push rod motor, and the driving end of the first lifting drive mechanism 6 is connected to the smoke pipe 1, and is used to drive the smoke pipe 1 to move relative to the table 4, so that the distance between the air inlet 121 of the smoke pipe 1 and the upper surface of the table 4 can be adjusted, thereby changing the position of the smoke inlet in the vertical direction, so that the smoke inlet faces the expected direction.

[0068] like Fig.10 As shown, the number of smoke tubes 1 is at least two; the smoking device includes a confluence cavity 8, the air outlet 111 of each smoke tube 1 is connected to the confluence cavity 8, and the guide channel 3 is connected to the confluence cavity 8, so that the guide channel 3 is connected to each air outlet 111 through the confluence cavity 8.

[0069] There are two smoke pipes 1, one smoke pipe 1 is responsible for absorbing the oil smoke of the left stove, and the other smoke pipe 1 is responsible for absorbing the oil smoke of the right stove. The oil smoke absorbed by each smoke pipe 1 first enters the confluence cavity 8, and then is input into the guide channel 3 by the confluence cavity 8 and discharged in a centralized manner.

[0070] The main pipe 11 is slidably connected to the confluence cavity 8 . The first lifting drive mechanism 6 is located in the confluence cavity 8 and connected to the confluence cavity 8 . The first lifting drive mechanism 6 can drive the main pipe 11 to rise and fall relative to the confluence cavity 8 .

[0071] The confluence cavity 8 is provided with a through hole, through which the main pipe 11 passes. The through hole limits the sliding of the main pipe 11, so that the main pipe 11 can only move in the inner and outer directions of the confluence cavity 8 without tipping over. The first lifting drive mechanism 6 is arranged in the confluence cavity 8 to adjust the vertical position of the main pipe 11 relative to the confluence cavity 8. The first lifting drive mechanism 6 can be connected to all the smoke pipes 1 to uniformly control the lifting and lowering of all the smoke pipes 1. The number of the first lifting drive mechanisms 6 can also be set to be the same as the number of the smoke pipes 1, and they are connected one by one, so as to individually control the vertical height position of each smoke pipe 1 relative to the confluence cavity 8.

[0072] The smoking device further includes a second lifting drive mechanism 7, which may also include a push rod motor. The driving end of the second lifting drive mechanism 7 is connected to the confluence cavity 8, and is used to drive the confluence cavity 8 to rise and fall. Driven by the second lifting drive mechanism 7, the confluence cavity 8 can be extended from the avoidance hole 41, and all the cigarette tubes 1 are pushed out together and switched to the working state. When the smoking task is completed, the second lifting drive mechanism 7 can be used to drive the confluence cavity 8 to drop below the table 4 and switch to the hidden state.

[0073] Through the cooperation of the first lifting mechanism and the second lifting mechanism, the smoke pipe 1 can be lifted in two stages and can reach a higher height.

[0074] like Figure 7 As shown, the smoking device further comprises a cover plate 5 , which is used to close the avoidance hole 41 when the smoke pipe 1 is located below the table 4 .

[0075] In this embodiment, the cover plate 5 is connected to the table top 4 by a hinge, and can be opened and closed after being turned over. In other feasible solutions, the cover plate 5 and the table top 4 can be connected by other movable connection modes, such as sliding connection.

[0076] Of course, the cover plate 5 can also be independent, that is, not connected to the table top 4. When in use, the cover plate 5 is buckled to cover the avoidance hole 41, and when not in use, it is moved away from the table top 4.

[0077] Finally, it should be noted that the above embodiments are only used to illustrate the technical solution of the utility model, rather than to limit it. Although the utility model has been described in detail with reference to the aforementioned embodiments, ordinary technicians in this field should understand that they can still modify the technical solutions recorded in the aforementioned embodiments, or replace some or all of the technical features therein with equivalents. However, these modifications or replacements do not make the essence of the corresponding technical solution deviate from the scope of the technical solution of the embodiments of the utility model.
