The particle oven comprises a driving assembly 3, the driving assembly 3 comprises a motor 31 and a feeding piece 32, the motor 31 is located below the second bottom wall 113, the motor 31 is far away from the combustion chamber 15, the motor 31 is far away from a heat source and a hot structural part, the heating degree of the motor 31 is reduced, and the service life of the motor 31 is prolonged. The motor 31 drives the feeding piece 32 to move, and the axis of the shaft of the motor 31 is coincident with the axis of the shaft of the feeding piece 32. The feeding member 32 comprises a spiral section 321 and a disc section 322, the spiral section 321 is connected with the disc section 322 and fixed to each other, the second channel 42 comprises a third opening 422, the third opening 422 is located at one end of the second channel 42 far away from the second opening 421, and the spiral section 321 of the feeding member 32 passes through the third opening 422, so that the spiral section 321 is partially or completely accommodated in the second channel 42. The second channel 42 is disposed obliquely, and the level of the second channel 42 at the end of the third opening 422 is lower than the level of the second channel 42 at the end of the second opening 421. The cross-sectional area of the disc section 322 is larger than that of the third opening 422, so that when the disc section 322 is close to the third opening, particles cannot flow out of the third opening 422, and the possibility of scattering of the particles is reduced. When the motor 31 drives the spiral section 321 of the feeding member 32, the spiral section 321 drives the particles from the vicinity of the third opening 422 of the second channel 42 to the vicinity of the second opening 421, and the particles are discharged from the second opening 421 out of the second channel 42 and flow into the third channel 43.

The wall of the third channel 43 may be composed of the second bottom wall 113 and a cover 431 above the second bottom wall 113, or a single cylinder may be provided. The second bottom wall 113 is designed to be inclined, when the particles are in the third channel 43, the particles are located above the second bottom wall 113, the inclined angle between the second bottom wall 113 and the horizontal plane is between 15 degrees and 60 degrees, preferably between 18 degrees and 45 degrees, such as 20 degrees, 25 degrees, 30 degrees, etc., if the angle is too small, the particles are easy to block in the third channel 43 when the particles fall down only by gravity, that is, the downward component of gravity is not enough to roll down the particles; if the angle is too large, the second bottom wall 113 is inclined too high, resulting in an unreasonable arrangement of the pellet oven space and more unused space, making the overall pellet oven bulky. Therefore, when the angle is between 15 and 60 degrees, the downward rolling of the particles can be met, and the miniaturization of the particle oven can be met.

During rotation of the drive assembly 3 for feeding, particles are intermittently retained from the second passage 42, and the discharged particles are introduced into the combustion chamber 15 along the third passage 43. After the particles flowing out of the second channel 42 enter the combustion chamber 15 at this time, the third channel 43 has no particles in the time period from the time when the particles flow out of the second channel 42 next time, so that the distance between the combustion chamber 15 and the particles in the second channel 42 can be kept, and the distance can be the length of the third channel 43, so that the flame in the combustion chamber 15 is far away from the particles in the second channel 42, the possibility that the flame in the combustion chamber 15 flees back to the particle bin through the feeding channel 4 is reduced, and the safety of the particle oven is greatly improved.

Specifically, the axis of the feeding member 32 is perpendicular to the plane of the second bottom wall 113, so that the overall space utilization rate is the highest, the structure is more compact, and the development of miniaturization of the particle oven is promoted. And the above vertical arrangement, when the length of the feeding member 32 is fixed, the distance between the motor 31 and the second bottom wall 113 is the farthest, when the temperature in the barbecue cavity 11 rises, the temperature of the bottom wall 111 rises, and the distance between the motor 31 and the second bottom wall 113 is the farthest, so that the safety and the service life of the motor 31 are improved; meanwhile, the second opening 421 of the motor 31 and the combustion chamber 15 form or approximate to a right triangle at three points, and the motor 31 and the combustion chamber 15 are the hypotenuses of the right triangle, that is, the motor 31 is far away from the combustion chamber 15, so that the safety of the motor is improved. Or say so, when motor 31 is when safe distance apart from second diapire 113, pay-off piece 32 adopts perpendicular setting for the length of pay-off piece 32 has reduced the materials of pay-off piece 32 promptly, has reduced manufacturing cost, reduces the whole weight of pay-off piece 32, and then has reduced the whole weight of granule oven, and portable shortens because of the distance again, has reduced the possibility of granule card material.

The cover body 431 on the third channel 43 can reduce the possibility that oil stains fall into the third channel 43 during barbecuing, so that the second bottom wall 113 at the third channel 43 is cleaner, the possibility that the particles roll off due to the oil stains on the second bottom wall 113 in the third channel 43 is reduced, the particles roll off more smoothly, and the user experience is improved. When the particles slide into the combustion chamber 15 from the second bottom wall 113, the position where the particles enter the combustion chamber 15 is located right above the igniter 6, i.e. the particles can directly fall on the igniter 6, thereby improving the ignition efficiency.
