[0016] The present invention will be further described in detail below in conjunction with the embodiments with reference to the drawings.

[0017] Embodiment 1: As shown in the figure, a smoking mechanism of an oven includes a smoking spice box 1 for placing smoking spices. A smoke-permeable opening 10 for the escape of smoke is provided on the smoking spice box 1. It also includes an external heating device 2 for heating the smoking spice box 1 at a high temperature. By heating the smoking spice box 1 with the heating device 2 at a high temperature, the smoking spices in the smoking spice box 1 are pyrolyzed to generate smoke.

[0018] Specifically, the upper opening of the smoking spice box 1 forms the smoke-permeable opening 10. This structure of the smoking spice box 1 is simple and easy to manufacture.

[0019] Specifically, the smoking spice box 1 is made of a high-temperature resistant metal material. This enables the smoking spice box 1 to withstand the high temperature of the heating device 2, avoiding deformation or damage and extending its service life; the metal transfers heat quickly, making the smoking spices evenly heated and improving the pyrolysis efficiency.

[0020] Specifically, a top cover 3 is spacedly arranged on the smoking spice box 1. The smoking spice box 1 is completely covered by the top cover 3. There is a smoke-permeable channel 31 for the outward escape of smoke between the top cover 3 and the top of the smoking spice box 1. The top cover 3 completely covers the smoking spice box 1. When this structure is applied and installed inside the furnace body of the oven A, the top cover 3 can be used to prevent the grease and food residues generated during the baking process from dripping into the smoking spice box 1, reducing the cleaning requirements and lowering the safety risk; there is a smoke-permeable channel 31 between the top cover 3 and the smoking spice box 1, which can make the smoke escape concentratedly in a specific direction, avoiding the dispersion of smoke and improving the smoking efficiency; in addition, the top cover 3 can also be used to limit the inflow of oxygen, maintaining a low-oxygen environment and promoting the pyrolysis rather than combustion of the smoking spices.

[0021] Specifically, the heating device 2 is one of the heaters in the oven cavity of oven A. The smoking spice box 1 and the top cover 3 are used to be installed in the oven cavity of oven A, and the smoking spice box 1 is close to the heater. The smoking spice box 1 has a mounting bracket 4 for installation into oven A. Directly using the built-in heater of oven A (such as an electric heating tube, a gas burner, etc.) as the heat source saves costs and space; the smoking spice box 1 and the top cover 3 are installed in the oven cavity of oven A, without occupying external space, keeping the appearance of oven A simple; the smoking spice box 1 close to the heater can quickly heat up, and the temperature control system of oven A can independently control this heater to adjust the smoking temperature.

[0022] Specifically, the heating device 2 is a gas heater. It has stable use and high heating efficiency, and is suitable for outdoor use without power supply.

[0023] An oven includes a smoking mechanism with the above structure. The smoking spice box 1 is detachably (such as by screwing and locking) fixedly installed on the inner wall of the oven cavity through the mounting bracket 4. One end of the top cover 3 is also detachably installed on the inner wall of the corresponding position of the oven cavity, blocking between the smoking spice box 1 and the baking grid A1. The smoking spice box 1 is close to the position of one of the heaters arranged in the oven cavity of oven A, and this heater can be independently controlled, which can effectively control the time to start smoking the food, so as to obtain a better smoking effect.

[0024] Embodiment 2: Other parts are the same as those in Embodiment 1. The difference is that the smoking mechanism further includes an outer housing 5 for installation outside oven A. The upper part of the outer housing 5 is open, and the top cover 3 is detachably arranged on the outer housing 5. A cavity 50 is formed between the outer housing 5 and the top cover 3. The smoking spice box 1 and the heating device 2 are both arranged in the cavity 50. The opening and closing device 20 of the heating device 2 is arranged outside the outer housing 5. A communication port A2 communicating with the oven cavity is provided on the side of oven A. An escape port Y1 for the smoke to escape is provided on the side of the top cover 3 or the outer housing 5. When the outer housing 5 is installed outside oven A, the escape port Y1 is hermetically communicated with the communication port A2. It forms a modular design, adapts to various oven models for use, and effectively reduces the transformation cost of the oven; this structure is suitable for installing the entire smoking mechanism outside oven A, which can be used to liberate the space inside oven A and increase the capacity of food baking; it forms an independent heat dissipation space, the oxygen concentration can be effectively controlled, and the cavity 50 structure effectively improves the heat efficiency, thereby effectively improving the utilization rate of the smoking spice; the outer housing 5 also realizes the stable installation of the heating device 2 and improves the safety of use at the same time.

[0025] Specifically, the heating device 2 is arranged at the bottom of the smoked spice box 1 and close to one of the side parts, so as to realize synchronous heating of the bottom and the corresponding side part of the smoked spice. The bottom heating ensures that the smoked spice is fully heated, improves the pyrolysis efficiency, the side heat source forms a convection cycle, improves the speed of smoke production, forms a unique "L-shaped" heat field distribution, effectively increases the heating area, and at the same time can form a gradient temperature control to achieve precise temperature control.

[0026] Specifically, both the outer housing 5 and the top cover 3 are made of high-temperature resistant metal materials, which can withstand the high temperature of the heating device 2, avoid deformation or damage, extend the service life, and improve the safety of use at the same time.
