In addition, the terms "first" and "second" are only used to distinguish in the description and have no special meaning.

[0048] like Figure 1 and Figure 2 As shown, an embodiment of the utility model provides a burner head assembly and a gas-electric cooker, the gas-electric cooker includes a burner head assembly, the burner head assembly includes a gas burner head, an electric ceramic stove assembly 2 and a lifting drive assembly 4, wherein the gas burner head includes a fire cover assembly 1, the fire cover assembly 1 is provided with a central through hole 11, and a plurality of inner ring fire holes 12 distributed at intervals along the circumference of the central through hole 11.

[0049] The electric ceramic stove assembly 2 is vertically movable in the central through hole 11, so that the electric ceramic stove assembly 2 can move back and forth between the working position and the idle position; when the electric ceramic stove assembly 2 is in the working position, the highest point of the electric ceramic stove assembly 2 is higher than the lowest point of the inner ring fire hole 12; when the electric ceramic stove assembly 2 is in the idle position, the highest point of the electric ceramic stove assembly 2 is not higher than the lowest point of the inner ring fire hole 12.

[0050] like Figure 1 As shown, when the gas burner is in use, the lifting drive assembly 4 controls the electric ceramic stove assembly 2 to descend to an idle position, so that the highest point of the electric ceramic stove assembly 2 is not higher than the lowest point of the inner ring fire hole 12, so that the inner ring fire of the gas burner can burn normally; Figure 2 As shown, when the electric ceramic stove assembly 2 is used alone, the lifting drive assembly 4 controls the electric ceramic stove assembly 2 to rise to the working position, so that the highest point of the electric ceramic stove assembly 2 is higher than the lowest point of the inner ring fire hole 12, and the heating surface of the electric ceramic stove assembly 2 is closer to the bottom of the pot. Most of the heat generated by the electric ceramic stove assembly 2 can act on the bottom of the pot, and the energy loss is small.

[0051] Exemplarily, when the electric ceramic stove assembly 2 is in the working position, the highest point of the electric ceramic stove assembly 2 is higher than the highest point of the inner ring fire hole 12. Such an arrangement can make the heating surface of the electric ceramic stove assembly 2 closer to the bottom of the pot.

When the driving unit 44 drives the transmission part 43 to rotate circumferentially, the transmission part 43 drives the connecting part 42 to rise and fall, thereby causing the electric ceramic stove assembly 2 to rise and fall synchronously.

[0061] In some other embodiments, the electric ceramic stove housing 21 and the base assembly 3 can also be slidably matched in the vertical direction using a slide groove and a slider to guide the lifting of the electric ceramic stove assembly 2 and limit the circumferential rotation of the electric ceramic stove assembly 2 relative to the transmission part 43.

[0062] In some embodiments, Figure 2 and Figure 3 As shown, a first limiting portion 411 is disposed at the lower end of the guide rod 41 , and an elastic element 45 is sleeved on the guide rod 41 .

The elastic element 45 adopts a tension spring, and the multiple elastic elements 45 arranged at intervals along the circumference of the electric ceramic stove assembly 2 are used to pull the electric ceramic stove assembly 2 upward.

[0066] In some embodiments, Figure 2 and Figure 3 As shown, the electric ceramic stove housing 21 includes an upper housing 211 and a lower housing 212, the upper housing 211 and the lower housing 212 are connected to form a receiving space with a top opening, and the electric ceramic stove assembly 2 also includes an electric ceramic stove body 22, which is disposed in the receiving space; the upper end of the connecting unit 25 is provided with a second limiting portion 251, and the lower end of the connecting unit 25 passes through the electric ceramic stove body 22 and the lower housing 212 and is connected to the connecting portion 42, and the electric ceramic stove body 22 and the lower housing 212 are sandwiched between the second limiting portion 251 and the connecting portion 42.

[0067] Specifically, the connection unit 25 is a fastener such as a bolt, etc., the rod of the fastener passes through the electric ceramic stove body 22 and the lower shell 212 and is fixed to the connection part 42, so that the electric ceramic stove body 22 and the lower shell 212 are clamped between the connection part 42 and the head of the fastener, thereby fixing the electric ceramic stove body 22 to the lower shell 212. Exemplarily, the connection part 42 and the connection unit 25 are fixed by welding.

[0068] In some embodiments, Figure 2 and Figure 3 As shown, the outer flange includes a first outer flange 2111 provided on the upper shell 211, and a second outer flange 2121 provided on the lower shell 212.

The top of the lower shell 212 is inserted into the upper shell 211 through the bottom opening of the upper shell 211. The top of the upper shell 211 is provided with an opening, and the edge of the top opening is provided with an inner flange 2112. The electric ceramic stove body 22 is provided between the inner flange 2112 and the top surface of the upper shell 211.

[0070] In some embodiments, Figure 2 and Figure 3 As shown, the electric ceramic stove assembly 2 further includes a microcrystalline glass plate 23 located above the electric ceramic stove body 22, and the microcrystalline glass plate 23 is sandwiched between the inner flange 2112 and the electric ceramic stove body 22 in the vertical direction. Specifically, the circumferential edge of the microcrystalline glass plate 23 is sandwiched between the inner flange 2112 and the upper surface of the electric ceramic stove body 22, and the microcrystalline glass plate 23 on the inner circumferential side of the inner flange 2112 is exposed through the top opening, and the upper surface of the microcrystalline glass plate 23 exposed through the top opening of the upper shell 211 forms the heating surface of the electric ceramic stove body 22. The heat generated by the operation of the electric ceramic stove body 22 is dissipated to the bottom of the pot body above through the microcrystalline glass plate 23.

[0071] When the electric ceramic stove assembly 2 is in the working position, the electric ceramic stove assembly 2 is lower than the top surface of the central through hole 11, so that the heat generated by the working electric ceramic stove main body 22 can be fully utilized by the pot body, and the bottom of the pot body can be prevented from contacting the microcrystalline glass plate 23 to protect the microcrystalline glass plate 23.

[0076] In some embodiments, Figure 2 and Figure 3 As shown, an air supply channel 100 is formed between the outer peripheral wall of the electric ceramic stove assembly 2 and the inner peripheral wall of the central through hole 11. When the gas burner is working, the air supply channel 100 can be used to supply air to the fire cover assembly 1 to meet the gas combustion requirements.

[0077] Exemplarily, the outer peripheral wall of the electric ceramic stove shell 21 and the inner peripheral wall of the central through hole 11 are spaced apart. In other words, the outer peripheral wall of the electric ceramic stove shell 21 and the inner peripheral wall of the central through hole 11 are spaced apart to form the air supply channel 100, which can also reduce the processing requirements for the outer peripheral wall of the electric ceramic stove shell 21 and the inner peripheral wall of the central through hole 11, avoid the problem of sticking when the electric ceramic stove assembly 2 is lifted or lowered, and improve the smoothness of the electric ceramic stove assembly 2 when it is lifted or lowered.

Exemplarily, the magnet 51 is arranged in the mounting through hole 421 and is located at the lower part of the mounting through hole 421.

[0079] The upper limit position of the rise of the electric ceramic stove body 22 is limited by the cooperation of the magnet 51 and the upper magnetic control switch 52, and the lower limit position of the descent of the electric ceramic stove body 22 is limited by the cooperation of the magnet 51 and the lower magnetic control switch 53.
