As shown in fig. 3 and 5, a heating cover 831 is disposed at the bottom of the smoking case 81, a heating opening 812 communicated with the heating cover 831 is disposed at the bottom of the smoking case 81, the secondary heating pipe 83 is disposed in the heating cover 831, a heat reflection protrusion 832 is further disposed at the bottom of the heating cover 831, the reflection protrusion 832 not only improves the structural strength of the bottom of the heating cover 831, but also reflects heat to the surroundings for diffusion, thereby preventing the heat at the bottom of the wood chip box 82 near the secondary heating pipe 83 from being too high, so that the wood chip box 82 is heated more uniformly, thereby improving the smoking effect, and the heating cover 831 effectively collects heat, thereby preventing the heat from being excessively lost due to the air flow in the smoking cavity 42, improving the heating effect on the wood chip box 82, and heating the wood chip box 82 through the secondary heating pipe 83 alone, instead of using the main heating pipe 52 mainly heating the inside of the furnace, thereby enabling the continuous performance of smoking time and smoking amount of the smoking mechanism to directly pass through the heating of the secondary heating pipe 83 Temperature and heating time are directly controlled, so that the smoke is more consistent with the use requirement, the smoking effect of food is improved, and the wood chip box assembly, the main heating pipe 52 and the auxiliary heating pipe 83 are not under the interior of the furnace body 1, so that water, oil, sundries and the like of the food are prevented from dropping onto the wood chip box assembly, the main heating pipe 52 and the auxiliary heating pipe 83, and the interference and maintenance cost is reduced.

As shown in fig. 3 and 5, the smoking mechanism, the main heating pipe 52, the convection fan 72, the motor 7, the control box 6 and other main components are all integrated in one furnace end shell 2, when needing to be maintained and replaced, the internal components can be directly maintained and replaced by opening the rear cover 21, the furnace end assembly can be detached alone to be replaced wholly, and the furnace end assembly can guarantee to smoke, the circulation flowing effect of heat and smoke in the furnace body 1 is improved, and the smoking effect of food is improved.

The implementation principle of the embodiment is as follows: the main components of the smoking mechanism, the main heating pipe 52, the convection fan blades 72, the motor 7, the control box 6 and the like are all integrated in one burner shell 2, when the maintenance and the replacement are needed, the internal components can be directly maintained and replaced by opening the rear cover 21, and the burner assembly can be detached independently for the whole replacement.

The furnace end assembly is used as an independent unit and is arranged at the back of the furnace body 1, so that the operation installation and after-sale maintenance operation of a production line are facilitated, the independent furnace end assembly can be used as a universal part to be applied to the furnace bodies 1 with different barbecue volumes and different appearance structures, and the universality of matched products is improved.

And the electric heating furnace end assembly is matched with convection fan blades 72, so that heat generated by the main heating pipe 52 can be timely transmitted to corners and parts in the furnace body 1, the convection of hot air in the furnace body 1 is greatly accelerated, the temperature rise in the furnace body 1 is improved, food in the furnace is heated more quickly and more uniformly, the consistency of the baking quality of the food is ensured, meanwhile, the baking time is shortened, and the purpose of energy conservation is achieved.

The auxiliary heating pipe 83 which is provided with independent heating wood chips and other smoke generating materials forms a smoking mechanism together with the wood chip box assembly and the heating cover 831, so that smoking time and smoking amount can be conveniently mastered, and the smoking mechanism is suitable for different smoking preferences of users.

The embodiments of the present invention are preferred embodiments of the present invention, and the scope of the present invention is not limited by these embodiments, so: all equivalent changes made according to the structure, shape and principle of the invention are covered by the protection scope of the invention.
