[0035] As an indispensable cooking appliance in modern kitchens, the development of ovens has undergone technological innovations from simplicity to complexity and from single-function to multi-function. With the progress of technology and consumers' continuous pursuit of cooking experiences, oven technology is constantly evolving, and the types of ovens are also increasing. As a traditional food processing method, smoked cooking is deeply loved by consumers for its unique flavor and taste. With the development of technology, some ovens with a smoking function have emerged on the market, aiming to enrich the taste of food and meet people's different needs.

[0036] However, there are still many limitations in the control of the smoking effect of existing smoked ovens. They often cannot accurately adjust the dosage of smoking materials and the concentration of smoke, resulting in the smoking effect being difficult to achieve the expected level, and the quality of products varying widely.

[0037] Based on this, the present application provides a smoke generating mechanism.

[0038] Embodiment 1

[0039] See Figures 1 to 2 As shown, a smoke generating mechanism includes:

[0040] A hopper 1, a discharge port 11 is provided at the bottom of the hopper 1, and a first feeding structure 12 is provided at the discharge port 11. The first feeding structure 12 is pivotally connected to the side wall of the discharge port 11 through a first rotating shaft;

[0041] A heating chamber 2 is provided below the hopper 1. The heating chamber 2 is communicated with the discharge port 11; a heating element 3 is provided outside one side wall of the heating chamber 2, and the heating element 3 is used to heat the side wall of the heating chamber 2; a smoke exhaust hole 21 is also provided on the heating chamber 2;

[0042] A first driving structure is provided outside the heating chamber 2. The first driving structure drives the first feeding structure 12 to rotate, so that the material in the hopper 1 enters the heating chamber 2 through the discharge port 11.

[0043] The above-mentioned smoke generating mechanism, which includes a hopper 1 and a first driving structure. The bottom of the hopper 1 is provided with a discharge port 11, and a first material distributing structure 12 is arranged at the discharge port 11. The first material distributing structure 12 is pivotally connected to the side wall of the discharge port 11 through a first rotating shaft. Below the hopper 1 is a heating chamber 2, and the heating chamber 2 is communicated with the discharge port 11. A heating element 3 is arranged outside one side wall of the heating chamber 2, and the heating element 3 is used to heat the side wall of the heating chamber 2. A smoke exhaust hole 21 is also arranged on the heating chamber 2. The first driving structure is arranged outside the heating chamber 2, and the first driving structure drives the first material distributing structure 12 to rotate, so that the material in the hopper 1 enters the heating chamber 2 through the discharge port 11. In actual application, the first material distributing structure 12 is a rotating blade, which is pivotally connected to the side wall of the discharge port 11 through a first rotating shaft. During use, by adjusting the rotation speed of the first material distributing structure 12, the feeding amount of the smoking material can be accurately controlled, so that the smoking material enters the heating chamber 2 according to requirements. The smoking material is heated by the heating element 3 in the heating chamber 2 to generate smoke, and the smoke flows from the smoke outlet to the place of use such as an oven to realize the smoking of food. This smoke generating mechanism significantly improves the smoking effect of food by accurately controlling the feeding amount of the smoking material and the generation amount of smoke, while improving the thermal efficiency and energy utilization rate, and is easy to operate and maintain.

[0044] Further, a second material distributing structure 22 is also arranged in the heating chamber 2. The second material distributing structure 22 includes an installation ring 221 and a plurality of material distributing plates 222. The installation ring 221 is pivotally connected to the side wall of the heating chamber 2 through a second rotating shaft. The plurality of material distributing plates 222 are uniformly distributed along the axial direction of the installation ring 221 on the side wall of the installation ring 221, and a material containing cavity 23 is formed between two adjacent material distributing plates 222. Specifically, the installation ring 221 is sleeved on the second rotating shaft and is pivotally connected to the side wall of the heating chamber 2. When the second rotating shaft rotates, the installation ring 221 is driven to rotate synchronously with the second rotating shaft, and the rotation speed of the installation ring 221 is controlled by the second rotating shaft. The plurality of material distributing plates 222 are connected to the side wall of the installation ring 221. The material containing cavity 23 between two adjacent material distributing plates 222 can hold the smoking material entering the heating chamber 2 from the discharge port 11. Therefore, by controlling the rotation speed of the second rotating shaft, the rotation speed of the installation ring 221 can be further controlled, and then the rotation speed of the material containing cavity 23 can be controlled, so as to adjust the generation amount of smoke.

[0045] Further, the second material distributing structure 22 further includes a support ring 223. The support ring 223 is arranged outside the installation ring 221, and the axis of the support ring 223 coincides with the axis of the support ring 223;

[0046] One end of the material pushing plate 222 is fixedly connected to the mounting ring 221, and the opposite end penetrates through the support ring 223 and extends towards the inner wall of the heating chamber 2. Specifically, one end of the material pushing plate 222 is uniformly distributed along the axial direction of the mounting ring 221 on the side wall of the mounting ring 221, and is driven to rotate by the mounting ring 221. The opposite end penetrates through the support ring 223 and then extends to have a small gap with the inner wall of the heating chamber 2. Similarly, both sides of the material pushing plate 222 have a small distance from the two axially opposite walls of the heating chamber 2, aiming to prevent jamming during rotation and also enable the smoked material in the material containing cavity 23 not to move along with the rotation of the cavity. When the second rotating shaft rotates, the support ring 223 connected to the mounting ring 221 by the material pushing plate 222 will rotate synchronously with the second rotating shaft and the mounting ring 221, that is, the three will maintain the same rotation speed, and the angular velocity of the rotation of the material pushing plate 222 is adjusted by the second rotating shaft. Among them, the support ring 223 increases the rigidity of the material pushing plate 222 and avoids breakage of the material pushing plate 222. Therefore, this structure can provide high stability.

[0047] Furthermore, a second driving structure is provided outside the heating chamber 2, and the second driving structure is used to drive the mounting ring 221 to rotate. Specifically, the second driving structure is connected to the second rotating shaft and is used to drive the second rotating shaft to rotate, thereby driving the mounting ring 221 to rotate.

[0048] Furthermore, an ash discharge port 24 is provided on one side of the heating chamber 2, and a receiving box 8 is provided below the ash discharge port 24. Specifically, the smoked material is heated in the heating chamber 2 to generate smoke, and at the same time, after burning out, it forms combustion ash. It rotates in the heating chamber 2 through the rotating material containing cavity 23 and is discharged when the corresponding material containing cavity 23 passes through the ash discharge port 24, and then falls into the receiving box 8. This design is beneficial to reducing the incombustibles in the heating chamber 2, avoiding the situation of less smoke production or no smoke production caused by insufficient heating or insufficient oxygen of the smoked material, can cooperate with the hopper 1 to feed and timely update the smoked material, and at the same time, the combustion ash in the receiving box 8 can be reused to improve the utilization rate of resources.

[0051] A second gear 5 is provided on the second rotating shaft, and the second gear 5 is provided outside the heating chamber 2. The second gear 5 is located below the first gear 4, and the axes of the first gear 4 and the second gear 5 are parallel to each other;

[0052] The first driving structure includes a servo motor 6 and a screw rod 7. The screw rod 7 is arranged between the first gear 4 and the second gear 5, and the screw rod 7 meshes with both the first gear 4 and the second gear 5. One end of the output of the servo motor 6 is fixedly connected to one end of the screw rod 7. Specifically, the servo motor 6 outputs rotational power through the screw rod 7. At the same time, the opposite end of the screw rod 7 drives the first gear 4 and the second gear 5 to rotate through helical ribs in a meshing manner, so that the first gear 4 and the second gear 5 rotate synchronously. Since the first rotating shaft and the second rotating shaft are respectively connected to the first gear 4 and the second gear 5, the rotation speeds of the rotating blade and the material deflector 222 can be controlled simultaneously, and the feeding amount of the smoking material and the smoke generation amount can be adjusted uniformly.
