[0025] The present invention will be further described in detail below with reference to the accompanying drawings and embodiments.

[0026] Example 1: As shown in the figure, a smoking mechanism for an oven includes a smoking spice box 1 for holding smoking spices, a smoke vent 10 for smoke to escape, and an external heating device 2 for heating the smoking spice box 1 at high temperature. The smoking spice box 1 is heated at high temperature by the heating device 2, causing the smoking spices in the smoking spice box 1 to pyrolyze and generate smoke.

[0027] Specifically, the upper opening of the smoke and spice box 1 forms a smoke-permeable opening 10. This type of smoke and spice box 1 has a simple structure and is easy to manufacture.

[0028] Specifically, the smoking spice box 1 is made of high-temperature resistant metal material. This allows the smoking spice box 1 to withstand the high temperature of the heating device 2, preventing deformation or damage and extending its service life; the metal quickly transfers heat, ensuring that the smoking spices are heated evenly and improving pyrolysis efficiency.

[0029] Specifically, a top cover 3 is spaced out on the smoke and spice box 1, completely covering the smoke and spice box 1. A smoke passage 31 for smoke to escape is provided between the top cover 3 and the top of the smoke and spice box 1. When this structure is installed inside the oven body of the oven A, the top cover 3 can prevent grease and food residue generated during the baking process from dripping into the smoke and spice box 1, reducing cleaning needs and safety risks. The smoke passage 31 between the top cover 3 and the smoke and spice box 1 allows smoke to escape from a specific direction, preventing smoke from spreading and improving smoking efficiency. Additionally, the top cover 3 can also restrict oxygen inflow, maintaining a low-oxygen environment and promoting the pyrolysis of the smoke and spices rather than combustion.

[0030] Specifically, heating device 2 is one of the heaters inside the oven cavity of oven A. The smoke and spice box 1 and top cover 3 are installed inside the oven cavity of oven A, with the smoke and spice box 1 located close to the heater. The smoke and spice box 1 has a mounting bracket 4 for installation inside oven A. Directly utilizing the built-in heater of oven A (such as an electric heating element or gas burner) as a heat source saves cost and space. The smoke and spice box 1 and top cover 3 are installed inside the oven cavity of oven A, not occupying external space and maintaining the simple appearance of oven A. The smoke and spice box 1, being close to the heater, can heat up quickly. The temperature control system of oven A allows for independent control of this heater, adjusting the smoking temperature.

[0031] Specifically, heating device 2 is a gas heater. It is stable in use, has high heating efficiency, and is suitable for outdoor use in the absence of power.

[0032] An oven includes a smoking mechanism with the above-described structure, wherein a smoking spice box 1 is detachably fixed to the inner wall of the oven cavity by means of a mounting bracket 4 (e.g., by screw locking), and one end of a top cover 3 is also detachably installed on the inner wall of the oven cavity at a corresponding position, separating the smoking spice box 1 and the grill rack A1. The smoking spice box 1 is located near one of the heaters provided in the oven cavity of the oven A. This heater can be independently controlled, which can effectively control the time when the food begins to be smoked, thereby obtaining a better smoking effect.

[0033] Example 2: The other parts are the same as in Example 1, except that the smoking mechanism also includes an outer shell 5 for installation outside the oven A. The upper part of the outer shell 5 is open, and the top cover 3 is detachably installed on the outer shell 5. A cavity 50 is formed between the outer shell 5 and the top cover 3. The smoking spice box 1 and the heating device 2 are both installed in the cavity 50. The opening and closing device 20 of the heating device 2 is installed outside the outer shell 5. The side of the oven A has a communication port A2 that communicates with the oven cavity. The top cover 3 or the side of the outer shell 5 is provided with an outlet Y1 for smoke to escape. When the outer shell 5 is installed outside the oven A, the outlet Y1 is sealed and connected to the communication port A2. The modular design allows for compatibility with various oven models, effectively reducing oven modification costs. This structure is suitable for installing the entire smoking mechanism on the outside of oven A, freeing up internal space and increasing food baking capacity. It creates an independent deheating space, allowing for effective control of oxygen concentration. The cavity 50 structure effectively improves thermal efficiency, thereby enhancing the utilization rate of smoking spices. The outer shell 5 also enables stable installation of the heating device 2 while improving safety during use.

[0034] Specifically, the heating device 2 is located at the bottom of the smoke and spice box 1 and near one of its sides. This allows for simultaneous heating of the bottom and the corresponding side of the smoke and spice box. Bottom heating ensures that the smoke and spice box is fully heated, improving pyrolysis efficiency, while the side heat source creates convection circulation, increasing the rate of smoke production and forming a unique "L-shaped" thermal field distribution, effectively increasing the heating area. At the same time, it enables gradient temperature control, achieving precise temperature control.

[0035] Specifically, both the outer casing 5 and the top cover 3 are made of high-temperature resistant metal materials. This allows them to withstand the high temperatures of the heating device 2, preventing deformation or damage, extending their service life, and improving safety during use.

[0036] An oven includes a smoking mechanism with the above-described structure, wherein the outer shell 5 is detachably installed on the outer side of the oven A, and the outlet Y1 has an inlet wall Y11 that extends into the communication port A2 to achieve the goal of introducing smoke into the oven cavity of the oven A with minimal loss.
