[0018] The concept, specific structure and technical effects of the utility model will be further described below in conjunction with the drawings to fully understand the purpose, features and effects of the utility model.

[0019] It should be noted that in the description of the present utility model, the terms indicating the direction or positional relationship such as "upper", "lower", "left", "right", "vertical", "horizontal", "inner", "outer", etc. are based on the direction or positional relationship shown in the drawings. This is only for the convenience of description and does not indicate or imply that the device or element must have a specific orientation, be constructed and operated in a specific orientation. Therefore, it should not be construed as a limitation to the present utility model.

[0020] Refer to Figures 1 to 7 As shown, it is a schematic diagram of a preferred embodiment of the present utility model. The present utility model relates to a smoke supply structure of a smoke oven, which includes a smoke main body 1 with a smoke chamber 11 and a smoke generator 2 provided on one side of the smoke main body 1 to supply smoke to the smoke chamber 11; the smoke generator 2 is juxtaposed and assembled with the smoke main body 1, so that the smoke generator is arranged outside the smoke main body, which is beneficial to planning the smoke chamber of the smoke main body and can effectively ensure the integrity and working performance of the smoke chamber, facilitate production and assembly, and is also beneficial to maintaining the smoke generator 2. The smoke generator 2 at least has a combustion box 21, a transfer bin 22 that connects the smoke outlet 211 of the combustion box 21 with the smoke chamber 11, and a fan 23 that supplies air to the transfer bin. The fan 23 blows external air into the transfer bin 22, so that the smoke in the transfer bin is transported to the smoke chamber 11 in a positive pressure manner; the smoke moves under positive pressure, and can achieve uniform movement and no dead angle of the smoke in the smoke chamber, effectively act on the food materials, and improve the quality and efficiency of the smoke processing.

[0021] Figure 2 , 3As shown in Figures 6, in this embodiment, the opening of the smoke outlet 211 of the combustion box 21 faces upward, and the transfer bin 22 is located on the upper side of the combustion box 21, and the transfer bin 22 has a hood 221 connected to the smoke outlet 211, a delivery port 222 connected to the smoke chamber 11, and an air inlet 223 facing the fan 23. The opening directions of the hood 221, the delivery port 222 and the air inlet 223 are different, so that the fan 23 blows external air into the transfer bin 22 through the air inlet 223 and then moves it toward the hood 221 and the delivery port 222 respectively. The wind moving through the hood enters the combustion box 21 and drives the smoke in the combustion box 21 to move out, and then is transported to the smoke chamber 11 through the delivery port 222. The transfer bin 22 and the combustion box 21 form a sealed space, so that external air enters through the air inlet 223 and can only be transported to the smoking chamber 11 from the delivery port 222. That is, the smoke movement system is effectively designed, which can well transport the smoke generated by the combustion of the fuel in the combustion box 21 to the smoking chamber 11 for food smoking processing.

[0022] Furthermore, in this embodiment, the opening of the hood 221 faces downward, the opening of the air inlet 223 faces backward, and the opening of the delivery port 222 faces leftward, and the horizontal heights of the openings of the hood 221 and the delivery port 222 are lower than the horizontal height of the opening of the air inlet 223. Such a design can realize multi-directional movement of air, and increase air fluidity and promote the effect of transporting smoke by utilizing the height difference. As shown in the figure, the hood 221 is long and narrow, matching the shape and size of the smoke outlet 211, and utilizing air to enter the combustion box and return with smoke; the air entering the combustion box in this embodiment can further promote fuel combustion and obtain better smoke. The delivery port 222 is in the form of a circular hole, utilizing contraction and pressurization to improve the balance and stability of the smoke. The air inlet 223 is mesh-shaped, which is conducive to cutting and diverting, and improving the air supply effect.

[0023] Furthermore, in the present embodiment, the transfer bin 22 is integrally constructed with the hopper 24 preset on the smoke generator 2, which is convenient for manufacture and assembly; the transfer bin 22 is arranged at the discharge end of the hopper 24, so that the hopper 24, the transfer bin 22 and the combustion box 21 form a stacked relationship of top, middle and bottom, with a compact and reasonable structure, which reduces the overall external dimensions of the product and facilitates feeding and air supply. Figure 5 , 6As shown in FIGS. 7, a gap feeder 25 is provided at the discharge end of the hopper 24. The gap feeder 25 includes a motor 251 and a rotor 252 driven by the motor to rotate. The rotor 252 is in the shape of a cylinder with an inner cavity 2522. The rotor 252 is installed in the transfer bin 22 and is horizontally mounted above the combustion box 21. A material port 2521 is provided on the outer periphery of the rotor 252. The material port 2521 extends along the axial direction of the rotor 252 and the extended length matches the discharge port of the hopper 24. By rotating the rotor 252, a working state is established where the material port 2521 alternately communicates with the hopper 24 and the combustion box 21, achieving automatic feeding and effectively controlling the feeding amount of the fuel to meet the requirements of automatic control. The air supply direction of the fan 23 is directly opposite to the free end 2523 of the rotor 252, and there is a certain gap between the free end 2523 and the inner wall of the transfer bin 22. The material port 2521 and the inner cavity 2522 extend from the free end 2523. An inwardly concave recoil groove 2524 is further provided on the free end 2523. The recoil groove 2524 extends along the axial direction of the rotor 252 and is distributed around the inner cavity 2522. The recoil groove 2524 is used to improve the air flow in the transfer bin 22. The design of the recoil groove 2524 allows the air sent by the fan 23 to form a recoil and collide with the newly incoming air, increasing the air flow in the transfer bin 22; this form is similar to the air returning from the combustion box and carrying out the smoke, making the air and smoke in the transfer bin 22 mixed evenly, and finally being transported to the smoking chamber 11 through the delivery port 222, with a good smoke delivery effect.

[0024] By designing the structure of the smoking main body and the smoke generator, the present utility model enables the smoke generator to be arranged outside the smoking main body, which is convenient for manufacturing, assembling and maintaining. And by designing a transfer bin and a fan on the smoke generator, the external air is blown into the transfer bin by the fan, so that the smoke in the transfer bin is transported to the smoking chamber of the smoking main body in a positive pressure manner, achieving uniform movement of the smoke in the smoking chamber without dead angles, improving the quality and efficiency of the smoking process. The present utility model can also adjust the fan to obtain different smoke delivery speeds and concentrations to meet different food processing requirements, greatly improving the usability of the oven and having good market benefits.

[0025] Although the preferred specific embodiments of the present utility model have been described above in conjunction with the accompanying drawings, the present utility model should not be limited to the exact same structure and operation as described above and shown in the drawings. For those skilled in the art of this technology, many equivalent improvements and changes can still be made to the above embodiments through logical analysis, reasoning or limited experiments without departing from the concept and scope of the present utility model, and these improvements and changes should all fall within the scope of protection required by the present utility model.
