[0026] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0027] Example

[0028] like Figures 1-5 As shown in the figure, an automatic rotary corn roaster according to one embodiment of the present invention includes a trough 1. A DC power socket 2 and a stepless speed regulator 3 are installed on the left side chamber of the trough 1, and a geared motor 4 is installed inside it. A motor gear 5 is installed on the output shaft end of the geared motor 4. A water basin 6 is placed at the bottom of the trough 1, and burners 7 are evenly distributed inside the trough 1. Ceramic cap burners 8 are installed on the burners 7, and the surface of the ceramic cap burners 8 is provided with honeycomb-shaped fire holes 9. A transmission box 10 is installed inside the trough 1, and a toothed belt 11 is installed in the transmission box 10 through a bearing. A rotating shaft roaster 12 is engaged in the transmission box 10, and a driven gear 13 is provided on the rotating shaft roaster 12. The structure features a wheel drive system with eight rotating shafts (12) that rotate simultaneously for grilling. A stepless speed regulator (3) adjusts the speed according to the food to prevent burning. It has six heating heads (7) and ceramic caps (8) with honeycomb-shaped fire holes (9), ensuring more even heating and heat dissipation. Due to the high-temperature resistance of the ceramic components, they are less prone to deformation and cracking under prolonged high temperatures, improving safety. A water basin (6) at the bottom prevents oil from dripping onto the surface during grilling and generates slight steam when water is added, increasing humidity to prevent food from burning too quickly and keeping it tender and juicy. The driven gear (13) meshes with the toothed belt (11), which in turn meshes with the motor gear (5).

[0029] like Figure 3As shown, in some embodiments, a gas inlet pipe 14 is installed in the machine slot 1, and ignition valves 15 are evenly distributed on the gas inlet pipe 14. The ignition part of the ignition valve 15 is embedded in the burner head 7, and an adjustment knob 16 is installed on the ignition valve 15. During operation, firstly, gas enters the corn machine through the gas inlet pipe 14. Then, the ignition valve 15 is precisely adjusted so that the user can control the gas flow rate by adjusting the knob 16. Next, the gas mixes with a portion of air, which is called primary air. The mixed gas is ejected from the burner hole of the burner head 7 and ignited by the ignition part of the ignition valve 15, thereby forming a flame.

[0030] like Figure 3 As shown, in some embodiments, the adjustment knob 16 extends outward from the front side of the slot 1, the number of ignition valves 15 is the same as the number of burner heads 7, and there are 6 burner heads 7. The adjustment knob 16 is mainly used to control the flame size. By rotating the knob, the gas intake can be adjusted, thereby controlling the intensity of the fire. Specifically, when rotating in the forward direction (clockwise), the outer ring flame gradually decreases, and after the outer ring goes out, the inner ring flame gradually decreases. When rotating in the reverse direction (counterclockwise), the inner and outer ring flames gradually decrease at the same time.

[0031] like Figure 2 As shown, in some embodiments, the left side chamber of the machine slot 1 is provided with heat dissipation holes 17. The geared motor 4 is electrically connected to the DC power socket 2 and the stepless speed regulator 3 through wires respectively. The heat dissipation holes 17 help to dissipate the heat generated by the electrical components in a timely manner by increasing the surface area and promoting air circulation, thus preventing overheating damage to the equipment. The DC power socket 2 is used to connect to the power supply. The main function of the stepless speed regulator 3 is to adjust the running speed of the motor, accelerating or decelerating it as needed. The running speed of the motor usually depends on the voltage and frequency of the power supply, and its speed is adjusted by changing the power supply frequency or voltage of the motor.

[0032] like Figure 3 As shown, in some embodiments, machine feet 18 are installed around the bottom of the machine slot 1, and pads 19 are provided on both sides of the bottom of the machine slot 1. The water basin 6 is placed on the pads 19. The machine feet 18 mainly serve to prevent shock, reduce noise, and provide stable support. The pads 19 are support structures used to place the water basin 6. During the baking process, the water basin 6 can prevent oil stains from dripping onto the table surface, and the addition of water can generate slight steam, increasing the humidity of the grilling environment. This can prevent food from burning too quickly, make the food more tender and juicy, and also reduce oil fumes.

[0033] like Figure 3 As shown, in some embodiments, the transmission box 10 is provided with a locking groove 20, and there are at least 8 locking grooves 20. The locking groove 20 is an assembly structure used for the installation and fixing of the rotating shaft heating rod 12.

[0034] like Figure 3 As shown, in some embodiments, the rotating shaft roasting rod 12 is inserted into the slot 20 by a bearing, and a handle 21 is installed at the end of the rotating shaft roasting rod 12. The device is equipped with 8 rotating shaft roasting rods 12, and each rod can hold corn up to 190mm in size and rotate and roast it at the same time.

[0035] like Figure 3 As shown, in some embodiments, the left side wall of the machine slot 1 is provided with a slot 22, and one end of the transmission slot box 10 extends from the slot 22 into the left side cavity of the machine slot 1. The slot 22 is a clearance structure to facilitate the meshing of the toothed belt 11 with the motor gear 5.

[0036] In use, this product adopts a belt and gear drive structure and is equipped with 8 rotating shaft roasting rods 12. Each roasting rod can hold corn up to 190mm in size and rotate and roast it simultaneously. (After the reduction motor 4 starts, the rotating motor gear 5 drives the toothed belt 11. Since the toothed belt 11 meshes with the driven gear 13 on the rotating shaft roasting rod 12, the rotating shaft roasting rod 12 is rotated under the action of the toothed belt 11.) This product has a total of 6 burner heads 7 and uses ceramic cover burners 8 with honeycomb-shaped fire holes 9. The porous ceramic design makes heating and heat dissipation more uniform. Due to the high temperature resistance of the ceramic plate, it will not deform even in high-temperature environments for a long time. To prevent breakage and improve safety, the machine is equipped with a water basin 6 at the bottom. During the grilling process, this prevents oil from dripping onto the work surface. Adding water generates slight steam, increasing the humidity of the grilling environment and preventing food from burning too quickly. This also makes the food more tender and juicy and reduces oil fumes. The included stepless speed controller 3 can adjust the speed of the geared motor 4 according to the food, thus preventing burning. The equipment uses a 12V DC motor and low-voltage power supply. It can be used by connecting to a 220V socket through an adapter or by connecting to a power bank through battery clips for convenient outdoor use.

[0037] In summary, the device employs a belt and gear drive structure, equipped with eight rotating shaft grill rods 12 that rotate simultaneously for grilling. The stepless speed regulator 3 can adjust the speed according to the food to prevent burning. It features six heating heads 7 and ceramic cover fire elements 8 with honeycomb-shaped fire holes 9, resulting in more even heating and heat dissipation. Due to the high-temperature resistance of the ceramic parts, they are not prone to deformation or cracking under high-temperature conditions for extended periods, improving safety. The water basin 6 at the bottom prevents oil from dripping onto the work surface during grilling, and the addition of water generates slight steam to increase the humidity of the grilling environment, preventing food from burning too quickly and keeping it more tender and juicy.

[0038] Finally, it should be noted that the above description is merely a preferred embodiment of this utility model and is not intended to limit the utility model. Although the utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
