The bracket 500 and the protective cover 400 can be engaged with each other to fix the protective cover 400, so as to ensure that the protective cover 400 is stably covered at the heating opening.

Preferably, the bottom inner side of the furnace body 100 is provided with a heat insulation board (not shown in the figure), which can effectively reduce heat dissipation in the furnace body 100 and help reduce the amount of fuel added due to the heat insulation requirement in the furnace body 100.

The furnace body 100 is further provided with a furnace cover 102, and one end of the furnace cover 102 is hinged to the top of the furnace body 100 through a hinge, so that the furnace cover 102 can be turned over and block the top opening of the furnace body 100, and heat dissipation in the furnace body 100 can be reduced, so that the interior of the furnace body 100 is further insulated.

It should be noted that the hinge member may adopt a hinge structure of the prior art, and will not be described herein.

Specifically, the outer sidewall of the furnace cover 102 is provided with a handle 1021 for the user to turn the furnace cover 102. The handle 1021 is made of heat insulating material, so that the user can be prevented from being scalded due to too high temperature.

Illustratively, the handle 1021 is made of bakelite material. The chemical name of bakelite is phenolic plastic, which has high mechanical strength, good insulativity, heat resistance and corrosion resistance, so that the handle 1021 can isolate most of heat.

Specifically, a storage table 103 is arranged on one side of the furnace body 100 away from the bin 200, and the storage table 103 can be used for storing seasonings, foods and the like, and the fumigating furnace can be moved by pushing and pulling the storage table 103.

Preferably, the side wall of the storage stage 103 is provided with hooks 1031, and the hooks 1031 can be used for hanging barbecue tools.

Specifically, the outer sidewall of the furnace body 100 is further provided with a hanging frame 104, and the hanging frame 104 can be used for placing paper towels or hanging towels.

In the specific content of the above embodiment, any combination of the technical features may be performed without contradiction, and for brevity of description, all possible combinations of the technical features are not described, however, as long as there is no contradiction between the combinations of the technical features, they should be considered as the scope of the description.

The foregoing detailed description of the embodiments presents only a few embodiments of the present utility model, which are described in some detail and are not intended to limit the scope of the present utility model. It should be noted that it will be apparent to those skilled in the art that several variations and modifications can be made without departing from the spirit of the utility model, which are all within the scope of the utility model. Accordingly, the scope of protection of the present utility model is to be determined by the appended claims.
