[0043] By adopting the above structure, the uniform temperature plate 200 and the fireproof plate 210 are connected and fixed together through the connecting column 220, and the two can reciprocate along the first sliding groove 120 through the connecting column 220, thereby achieving the effect of opening or closing the fire hole 111, and the structure is simple and convenient to operate.

[0044] It can be understood that, referring to Figures 1 to 6 The number of the first sliding grooves 120 is two, the two first sliding grooves 120 are arranged side by side along the width direction of the oil guide plate 100, and two connecting columns 220 are movably arranged in each first sliding groove 120, thereby not only making the connection between the uniform temperature plate 200 and the fireproof plate 210 more firm and stable, but also making the movement of the uniform temperature plate 200 and the fireproof plate 210 more smooth and stable. Of course, the number of the first sliding grooves 120 can be one, three or more besides two, and the number of the connecting columns 220 arranged in each first sliding groove 120 can be one, three or more besides two, and the present utility model does not make specific limitation thereon.

[0045] It can be understood that in order to realize the connection between the heat uniformizing plate 200 and the fire blocking plate 210 and the sliding connection between the two and the oil guide plate 100, in addition to the above structure, the heat uniformizing plate 200 and / or the fire blocking plate 210 can be provided with a second sliding groove arranged along the length direction of the oil guide plate 100, and the oil guide plate 100 is provided with at least one protruding part movably arranged in the second sliding groove. Of course, in addition thereto, the heat uniformizing plate 200 and the fire blocking plate 210 can be directly connected into a whole through a connecting plate located outside the oil guide plate 100, so that the oil guide plate 100 is movably arranged between the heat uniformizing plate 200 and the fire blocking plate 210, thereby realizing the connection between the heat uniformizing plate 200 and the fire blocking plate 210 and the sliding connection between the two and the oil guide plate 100. The specific connection structure between the heat uniformizing plate 200, the fire blocking plate 210 and the oil guide plate 100 is not limited in the utility model.

[0047] Through the above structure, the fire blocking plate 210 can be directly moved by the pull rod 230 to drive the heat uniformizing plate 200 to move synchronously, thereby realizing the opening or closing of the fire hole 111. Since the pull rod 230 extends from the inside of the heat transfer cavity 310 to the outside of the heat transfer cavity 310, the user can conveniently operate the pull rod 230, and the temperature of the outer end of the pull rod 230 is low, so as not to cause scalding to the user, thereby not only facilitating the user operation, but also protecting the user and improving the user experience.

[0048] With reference to Figures 1 to 6 In some embodiments, the pull rod 230 is specifically in U shape, and both ends of the pull rod 230 are arranged on the fire blocking plate 210, thereby facilitating the user to operate the pull rod 230.

[0049] It can be understood that the pull rod 230 can be arranged on the heat uniformizing plate 200 or on the fire blocking plate 210, or the pull rod 230 can be arranged on both the heat uniformizing plate 200 and the fire blocking plate 210, and the utility model does not make specific limitation thereon.

[0050] With reference to Figures 1 to 6The heat transfer cavity 310 of the furnace head is further provided with a combustion chamber 360, and the oil guide plate 100, the temperature equalizing plate 200 and the fire baffle 210 are all located above the combustion chamber 360. The fire outlet 110 of the oil guide plate 100 is located directly above the combustion chamber 360. When using open fire grilling, the flame generated by the combustion of fuel in the combustion chamber 360 can directly flow upward to the fire outlet 110 and flow out upward from the fire outlet hole 111, which is beneficial to improve the heat transfer efficiency. When using no open fire grilling, the heat generated by the combustion of fuel in the combustion chamber 360 can be directly conducted upward to the temperature equalizing plate 200, and then the heat is uniformly conducted to the oil guide plate 100 through the temperature equalizing plate 200, so that better temperature equalizing effect and heat transfer efficiency can be achieved.

[0051] With reference to Figure 5 and Figure 6 In some embodiments, the outer side of the furnace body 300 is provided with a cover body 320, the cover body 320 covers the outer periphery of the pull rod 230, and the bottom wall of the cover body 320 is provided with an operation opening 321.

[0052] In the above structure, since the pull rod 230 extends partially to the outer side of the furnace body 300 to facilitate user operation, the cover body 320 can protect the pull rod 230. When it is necessary to switch the grilling mode, the user can push and pull the pull rod 230 from the operation opening 321 below the cover body 320, which is convenient for operation and can prevent the pull rod 230 from being accidentally pulled or pushed.

The support portion 323 can support the cutting board 370 and other objects. When placed, the cutting board 370 only needs to be inserted into the cover body 320 from the insertion opening 322 and placed on the support portion 323. This structure not only facilitates the storage of the cutting board 370 and other objects, but also blocks the operation opening 321 by the cutting board 370 and other objects, so that the pull rod 230 is limited inside the cover body 320, thereby further preventing the pull rod 230 from being accidentally pushed or pulled or damaged.

[0055] With reference to Figures 1 to 6 With reference to Figures 1 to 6In some embodiments, the oil guide plate 100 is arranged to be inclined downward along the left-right direction of the furnace body 300, and the lower end of the oil guide plate 100 is arranged to be spaced from the inner wall of the heat transfer cavity 310 and forms the oil drip groove 330, the inner wall of the heat transfer cavity 310 is provided with an oil collecting member 340 located below the oil guide plate 100, the oil collecting member 340 has an oil collecting groove 341 located below the oil drip groove 330 and opening towards the oil drip groove 330; the furnace body 300 is further provided with an oil discharging member 350 connected to the oil collecting member 340 and extending outward to the outside of the heat transfer cavity 310, the oil discharging member 350 is provided with an oil discharging groove 351 in communication with the oil collecting groove 341, and the oil discharging groove 351 extends downward to the outside of the heat transfer cavity 310.
