[0023] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0024] Please see Figure 1-5This utility model provides an embodiment of an airflow puffing popcorn machine, comprising a base box 1, a base 2 fixedly installed below the base box 1, an puffing box 3 arranged above the base box 1, a puffing barrel 4 rotatably installed inside the puffing box 3, a fan 11 fixedly installed inside the base box 1 (the fan 11 is a high-temperature resistant fan), an electric heating tube 12 fixedly installed above the fan 11 inside the base box 1, a flow hole 102 provided on the upper end surface of the base box 1, and a slot provided on the lower end surface of the puffing box 3. 301. A reflux hole 101 is provided on the rear end face of the bottom box 1. A lower reflux pipe 8 is fixedly installed at the rear end of the bottom box 1. The lower reflux pipe 8 is connected to the bottom box 1 through the reflux hole 101. An upper reflux pipe 9 is fixedly installed above the lower reflux pipe 8. One end of the upper reflux pipe 9 is fixedly connected to the puffing box 3. A filter plate is provided at the connection between the upper reflux pipe 9 and the puffing box 3 to retain debris and impurities and prevent debris and impurities from flowing into the upper reflux pipe 9. The upper reflux pipe 9 is a heat-resistant long flexible tube.

[0025] The blower 11 is started to draw air from below and transport it upwards. The rising airflow is heated by the electric heating tube 12. The heated airflow flows into the puffing box 3 through the flow hole 102 and the slot 301 to puff the popcorn. Then, the air in the puffing box 3 can circulate back to the bottom box 1 through the upper return pipe 9, the lower return pipe 8 and the return hole 101. This achieves airflow circulation heating, avoids the large amount of extra energy required to reheat the external cold air from a low temperature to a high temperature, reduces energy waste, reduces production costs and increases practicality.

[0026] Please see Figure 3 and Figure 4 Inside the puffing box 3, a miscellaneous material box 7 is provided below the puffing barrel 4. A dust filter plate 701 is fixedly installed below the miscellaneous material box 7. One end of the miscellaneous material box 7 extends slidably to one side end face of the puffing box 3.

[0027] The inclusion box 7 facilitates the collection of debris and impurities generated during popcorn making, and the dust filter plate 701 effectively filters these impurities, allowing airflow to pass through the inclusion box 7 stably. At the same time, one end of the inclusion box 7 slides to one side of the puffing box 3, allowing the inclusion box 7 to be pulled out from the puffing box 3 for internal impurity cleaning, increasing its practicality.

[0028] Please see Figure 3 and Figure 4 A pad 10 is symmetrically arranged on both sides below the miscellaneous material box 7. The pad 10 is fixedly connected to the puffing box 3. A limit baffle 19 is provided on one side of the puffing box 3 along one side of the miscellaneous material box 7. The upper end of the limit baffle 19 is rotatably connected to the puffing box 3 through a rotating shaft.

[0029] The pad 10 provides stable support for the waste box 7, ensuring that the waste box 7 remains horizontal in the puffing box and guaranteeing the stability of the filtration process. The limiting baffle 19 limits the waste box 7 and prevents it from sliding out of the puffing box 3 on its own.

[0030] Please see Figure 3 A mesh ring plate 401 is fixedly installed inside the puffing barrel 4. One end of the puffing barrel 4 extends to the outside of the puffing box 3. A barrel cover 5 is provided at one end of the puffing barrel 4. A motor 6 is fixedly installed on one side of the puffing box 3. The output end of the motor 6 is fixedly connected to the puffing barrel 4.

[0031] The mesh ring plate 401 allows airflow into the puffing barrel 4, increasing the tumbling and stirring effect of the corn kernels within the puffing barrel 4. This enables the corn kernels to be heated and puffed more evenly. The drive of the motor 6 allows the puffing barrel 4 to rotate stably and evenly, ensuring the smooth progress of the puffing process.

[0032] Please see Figure 1 , Figure 2 and Figure 5 One side of the puffing box 3 is rotatably connected to the bottom box 1 via a hinge. A fixing block 14 is fixedly installed on the other side of the puffing box 3. An installation plate 15 is provided at the rear end of the fixing block 14. The lower end of the installation plate 15 is fixedly connected to the bottom box 1. A compression spring 16 is fixedly installed at the rear end of the installation plate 15. A pull plate 17 is fixedly installed at the rear end of the compression spring 16. A fixing post 18 is provided inside the compression spring 16. The rear end of the fixing post 18 is fixedly connected to the pull plate 17. The front end of the fixing post 18 slides through the fixing block 14.

[0033] The hinge connection allows the puffing box 3 to rotate at a certain angle relative to the bottom box 1, facilitating the tilting of the puffing bucket 4 and promoting popcorn dispensing. The fixing block 14, mounting plate 15, compression spring 16, pull plate 17, and fixing column 18 serve to fix the puffing box 3. When the puffing box 3 is in normal working condition, it ensures a firm and stable connection between the puffing box 3 and the bottom box 1. At the same time, simply pulling the pull plate 17 stretches the compression spring 16, allowing the fixing column 18 to disengage from the fixing block 14, which facilitates the rotation of the puffing box 3 and increases its practicality.

[0034] Please see Figure 4 A sealing ring 13 is fixedly installed on the outside of the slot 301 below the puffing box 3. The sealing ring 13 is located inside the flow hole 102.

[0035] During the airflow circulation heating process, the sealing ring 13 can effectively prevent gas from leaking from the gap between the puffing box 3 and the bottom box 1, ensuring the sealing of the airflow circulation path, so that the heated gas can all enter the puffing box 3 to puff the corn kernels, thereby improving the utilization rate of thermal energy.

[0036] Working principle: When in use, corn kernels are added to the puffing barrel 4, and the blower 11 is started to draw air from the bottom and transport it upward. The air is heated by the electric heating tube 12 to form a high-temperature airflow, which enters the puffing box 3 through the flow hole 102 and the slot 301. The high-temperature airflow acts on the corn kernels in the puffing barrel 4, so that they are heated and puffed evenly. Then, the airflow carrying heat returns to the bottom box 1 through the upper return pipe 9 and the lower return pipe 8 and the return hole 101, forming a closed loop. At the same time, the motor 6 drives the puffing barrel 4 to rotate. The internal mesh ring plate 401 facilitates the flow of air and ensures that the corn kernels are puffed evenly, thus realizing the airflow puffing of corn kernels and increasing practicality.

[0037] It will be apparent to those skilled in the art that this invention is not limited to the details of the exemplary embodiments described above, and that it can be implemented in other specific forms without departing from the spirit or essential characteristics of this invention. Therefore, the embodiments should be considered illustrative and non-limiting in all respects, and the scope of this invention is defined by the appended claims rather than the foregoing description. Thus, it is intended that all variations falling within the meaning and scope of equivalents of the claims be included within this invention. No reference numerals in the claims should be construed as limiting the scope of the claims.
