For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0041] like Figure 1 and Figure 2 As shown, the smoking device provided by the utility model includes: a smoke machine 1 and a guide channel 2, the smoke outlet of the smoke machine 1 is provided with a first docking structure 11, and the inlet of the guide channel 2 is provided with a second docking structure 21 connected to the first docking structure 11.

[0042] like Figure 2As shown, the guide channel 2 is arranged on the table of the smoking device, and the second docking structure 21 is arranged on the table. The range hood 1 can be used in conjunction with the table, that is, the first docking structure 11 and the second docking structure 21 are connected, and the first docking structure 11 and the second docking structure 21 are docked to form a transition airway connecting the range hood 1 and the guide channel 2. After the range hood 1 is started, an airflow flowing through the transition airway will be generated, from the range hood 1 to the direction of the guide channel 2. There is at least one section of the transition airway that is a Venturi structure, and the inner diameter of the Venturi structure decreases first and then increases. Among them, the Venturi structure may cause the Venturi effect. The principle of the Venturi effect is that when the gas or liquid flows in the Venturi tube, at the narrowest part of the pipe, the dynamic pressure (velocity head) reaches the maximum value, and the static pressure (resting pressure) reaches the minimum value. The velocity of the gas (liquid) increases because the cross-sectional area of ​​the flow is reduced.

[0043] After the range hood 1 is started, the external fumes enter from the smoke inlet on the side wall of the range hood 1, and then flow out from the first docking structure 11 under the action of the fan. The fumes flow from the range hood 1 to the guide channel 2. The fumes pass through the Venturi structure, and the cross-sectional area of ​​the path of the Venturi structure first decreases and then increases, forming a Venturi tube effect, which increases the flow rate, makes the exhaust of fumes smooth, and the exhaust effect is more obvious, thereby improving the user experience and facilitating user use.

[0044] In one feasible scheme, the Venturi structure is completely located on the first docking structure 11; in another feasible scheme, the Venturi structure is completely located on the second docking structure 21, and after the first docking structure 11 and the second docking structure 21 are connected, the Venturi structure is located near the connection position.

[0045] In this embodiment, a portion of the Venturi structure is located on the first docking structure 11 , and another portion is located on the second docking structure 21 . After the first docking structure 11 and the second docking structure 21 are connected, a complete Venturi structure is formed.

[0046] Specifically, Figure 2 As shown, from the direction of the range hood 1 toward the guide channel 2, the first docking structure 11 includes a first gradient section 111 and a first connecting section 112 connected in sequence, and the inner diameter of the first gradient section 111 gradually decreases; from the direction of the range hood 1 toward the guide channel 2, the second docking structure 21 includes a second connecting section 211 and a second gradient section 212 connected in sequence, and the inner diameter of the second gradient section 212 gradually increases; the first connecting section 112 and the second connecting section 211 are plugged in.

[0047] The upper opening of the first gradient section 111 is a first wide opening, and the lower opening is a first narrow opening. The diameter of the first wide opening is larger than the diameter of the first narrow opening. The inner diameter of the first gradient section 111 gradually decreases from the first wide opening to the first narrow opening. The first wide opening is connected to the housing of the range hood 1. The first narrow opening is connected to the upper end of the first connecting section 112. The lower opening of the second gradient section 212 is a second wide opening, and the upper opening is a second narrow opening. The diameter of the second wide opening is larger than the diameter of the second narrow opening. The inner diameter of the second gradient section 212 gradually decreases from the second wide opening to the second narrow opening. The second wide opening is connected to an opening at one end of the guide channel 2. The second narrow opening is connected to the lower end of the second connecting section 211. Along the length direction of the first connecting section 112, the inner diameter of the first connecting section 112 remains unchanged; along the length direction of the second connecting section 211, the inner diameter of the second connecting section 211 remains unchanged. The first connecting section 112 is inserted into the second connecting section 211 to achieve interference fit.

[0048] The smoking device comprises a table top, the guide channel 2 passes through the table top, and the second docking structure 21 is arranged on the table top.

[0049] There is also a stove on the table, and the second docking structure 21 is located between the two stoves. The range hood 1 can smoke from the left or right side of the stove. The guide channel 2 is hidden under the table. The range hood 1 is placed on the table after docking with the guide channel 2.

[0050] The table top is provided with legs 3 for supporting the bottom surface of the range hood 1 to prevent the bottom surface of the range hood 1 from completely contacting the table top.

[0051] The number of the legs 3 can be three or four, and the legs 3 are in contact with the range hood 1, thereby preventing the bottom surface of the range hood 1 from completely contacting the tabletop. When the range hood 1 is separated from the tabletop and used alone on the tabletop, the bottom of the range hood 1 is less stained with oil, thereby preventing the tabletop from being contaminated.

[0052] A battery module 41 is arranged in the range hood 1, a first charging structure 42 is arranged on the table top, a second charging structure 43 is arranged on the range hood 1, and the second charging structure 43 is connected to the battery module 41; the first charging structure 42 and the second charging structure 43 are used to cooperate in charging the battery module 41 after the range hood 1 is connected to the table top.

[0053] The battery module 41 provides power for the normal operation of the range hood 1. The first charging structure 42 and the second charging structure 43 can be a plug and a socket respectively, or can be a wireless charging component. In this embodiment, a plug-in conductive structure (plug and socket) is adopted. When the range hood 1 is placed in a fixed position, the plug on the table can be inserted into the socket at the bottom of the range hood 1 to achieve electrical connection. That is to say, when the range hood 1 is used in conjunction with the table, the battery module 41 is always charged.

[0054] The smoking device also includes a lifting drive mechanism 5; the lifting drive mechanism 5 is located below the table top; the table top includes a first part 61 and a second part 62, the second docking structure 21 is arranged on the second part 62, and the second docking structure 21 rises and falls together with the second part 62; an avoidance hole is arranged on the first part 61, and the second part 62 is located in the avoidance hole; the driving end of the lifting drive mechanism 5 is connected to the second part 62, and is used to drive the second part 62 to perform a lifting movement relative to the first part 61, so that the smoke machine 1 placed on the second part 62 can descend to below the table top through the avoidance hole.

[0055] The lifting drive mechanism 5 may include a push rod motor, the motor of the push rod motor is fixed, and its telescopic drive end is connected to the second part 62. When the first part 61 and the second part 62 are at the same horizontal position, the two form a complete plane, and the range hood 1 is placed on the second part 62. In order to improve the stability of placement, a connection structure such as a buckle structure can be correspondingly provided on the second part 62 and the range hood 1. When the range hood 1 is not needed, the lifting drive mechanism 5 can be used to drive the second part 62 to descend, so that the range hood 1 descends below the upper surface of the first part 61, and the top surface of the range hood 1 can be flush with the upper surface of the first part 61. The top of the range hood 1 can also be covered with a cover plate, so that the first part 61 and the cover plate form a complete plane.

[0056] A guide channel 7 extending downward from the avoidance hole is provided below the table top, and the range hood 1 moves in the guide channel 7 .

[0057] The range hood 1 is always raised and lowered in the guide channel 7 , and the guide channel 7 serves as a limit in the circumferential direction of the range hood 1 to avoid the range hood 1 from tilting during the raising and lowering process.

[0058] A connection structure is provided between the range hood 1 and the table top to connect the range hood 1 to the table top. The connection structure may be a buckle structure, a magnetic structure, etc., to improve the connection firmness between the range hood 1 and the table top and prevent the range hood 1 from tipping over relative to the table top.

[0059] Specifically, corresponding first magnets and second magnets may be disposed on the bottom surface and the inside of the table top of the range hood 1. The first magnet and the second magnet may attract each other. When the first magnet and the second magnet attract each other, the range hood 1 and the table top may be automatically positioned.

[0060] The smoking device also includes an outer shell located above the table top, a fan assembly 8 is arranged inside the outer shell, the other end of the guide channel 2 is connected to the outer shell, and a top smoke inlet is arranged on the outer shell. The negative pressure generated by the fan assembly 8 can act on the top smoke inlet, and can also act on the range hood 1 through the guide channel 2.

[0061] When the hood 1 on the table is not sufficient to completely absorb the oil smoke, the fan assembly 8 can be started to draw smoke through the top smoke outlet to reduce the escape of oil smoke.
