Currently, the stability of circuit components and the convenience of assembly during the heating process are not good, and circuit instability is prone to occur. Summary of the invention

[0003] Based on this, it is necessary to provide a plasma heating component and an electric stove to address the problem of circuit instability.

[0004] A plasma heating assembly comprises: a plasma rod, the plasma rod comprising a discharge head and a connecting rod, the discharge head being connected to the connecting rod; a first electrical connection ring, the first electrical connection ring being provided with a plurality of first electrical connection points, the plurality of first electrical connection points being at least partially electrically connected, the plurality of first electrical connection points being arranged along the circumference of the first electrical connection ring, the first electrical connection ring being used to be electrically connected to a high voltage device; a second electrical connection ring, the second electrical connection ring being provided with a plurality of plug holes and a plurality of second electrical connection points, the plurality of plug holes and the plurality of second electrical connection points being arranged along the circumference of the second electrical connection ring, the plug holes being arranged adjacent to the second electrical connection points, the adjacent plug holes and the second electrical connection points being electrically connected, the number of the plasma rods being multiple, the connecting rods of the plasma rods being plugged into the plug holes, the connecting rods being arranged on the second electrical connection ring; and a plurality of capacitors, one end of each of the capacitors being electrically connected to the first electrical connection point, and the other end being electrically connected to the second electrical connection point.

[0005] The plasma heating assembly disclosed in the present application is electrically connected to the high-voltage device through the first electrical connection ring, and the first electrical connection ring can be powered by the high-voltage device. For example, when the pot body needs to be heated, a gap is formed between the discharge head and the pot body, and when the discharge is performed on the discharge head, the air will be broken down to form plasma. The heat generated in this process will act on the pot body to heat it. During the circuit transmission process, the first electrical connection ring and the second electrical connection ring can be used to power the plasma rod respectively, and the assembly structure is simple. The current output to the plasma needle can be limited by setting the capacitor, the plasma needle can be protected, and the safety can be improved at the same time.

[0006] In one embodiment, the first electrical connection ring includes a first substrate and a first metal coating, the first metal coating is disposed on the first substrate to form a first conductive line, and the plurality of first electrical connection points are connected through the first conductive line.

The capacitor is sensitive to temperature, and the small temperature rise of the capacitor can avoid the influence on normal use.

[0011] In one embodiment, an insulating layer and a heat-insulating layer are further included, wherein the insulating layer is located above the heat-insulating layer, one side of the connecting rod passes through the insulating layer and the heat-insulating layer and extends to below the heat-insulating layer, the discharge head is located above the insulating layer, and the first electrical connection ring and the second electrical connection ring are located below the heat-insulating layer. The provision of the insulating layer can avoid the high-voltage electricity transmission of the plasma rod, and the heat generated by the plasma rod during operation can be transferred to the first electrical connection ring and the second electrical connection ring through the heat-insulating layer. Since the capacitor is sensitive to heat, the influence of heat on the capacitor is avoided, the working stability is improved, and the service life is increased.

[0012] In one embodiment, the first electrical connection ring is provided with a first mounting port, the number of the first mounting ports is multiple, and the multiple first mounting ports are arranged along the circumference of the first electrical connection ring, and the second electrical connection ring is provided with a second mounting port, the number of the second mounting ports is multiple, and the multiple second mounting ports are arranged along the circumference of the second electrical connection ring. By providing the first mounting port on the first electrical connection ring, the installation of the first connection ring can be facilitated, and the first electrical connection ring can be more conveniently connected to other components. The provision of multiple first mounting ports can make the assembly more stable. The provision of the mounting port on the second electrical connection ring also makes the assembly easier.

[0013] In one embodiment, the first electrical connection ring and the second electrical connection ring are connected via a connection plate. Connecting the first electrical connection ring and the second electrical connection ring via the connection plate allows the first electrical connection ring and the second electrical connection ring to be assembled into a whole, and the whole parts are directly assembled, and the connection method is simple.

[0014] In one embodiment, the end of the plasma rod where the discharge head is located and the capacitor are located on opposite sides of the second electrical connection ring. By setting the positions of the discharge head and the capacitor, the distance between the capacitor and the discharge head can be made farther, ensuring that the capacitor is less affected by the discharge head.

[0015] In one embodiment, the plasma rod is made of stainless steel, and the plasma rod and the second electrical connection ring are welded by copper solder, which can better connect the stainless steel and the second connection ring.

[0016] An electric stove comprises: the above-mentioned plasma heating component; a high-voltage device, which is electrically connected to the first electrical connection ring of the heating component; a shell component, on which the plasma heating component is arranged; and a control device, which is electrically connected to the high-voltage device and the plasma heating component.

[0017] The plasma heating component can be powered by a high-voltage device. When working, the plasma heating component will break through the air to generate plasma. The heat generated by the plasma will heat the placed pots. This heating method avoids the need for gas, but also has the combustion effect of flames.
