Description

Double-discharge-area burner and electric flame stove Technical Field The utility model relates to an electric flame stove. Background The electric flame stove is also called as a plasma stove, and is a novel flame generation mode, an electric field with high frequency change is adopted, two electrodes generate an electric arc phenomenon under a certain voltage, the electric arc is a beam of high-temperature ionized gas, and the electric flame stove uses continuous electric arc as energy for heating a pot body. The utility model patent with the application number 202311369153.9 discloses a furnace end for rotating working medium jet flow, which comprises a shell, a plurality of cathode flame tubes which are arranged on the shell and are of hollow structures, a plurality of insulating seats and a plurality of anode needles which are arranged on the insulating seats, wherein a plurality of air inlet holes are arranged at the bottoms of the insulating seats, and the air inlet holes are obliquely designed and are used for manufacturing air fluid rotating in an electric arc generating space. However, in the above patent, the plasma moves to the outside of the flame tube rapidly with the air flow, and the electron density cannot be increased, which results in low efficiency, and even if a high power current is input, the energy input by the high power is difficult to be converted into the "high energy state" (the excited state and the dissociated state of the particles) of the plasma, but rather a large amount of loss is generated. In addition, the anode needle of the current electric flame stove generates high temperature of thousands ℃ when discharging, and the high temperature is transmitted to the circuit board through the conductor electrically connected with the anode needle, so that the electronic element is overheated and damaged. Said utility model patent has cyclone air inlet hole, and makes external rotary air flow cooling insulating seat, but its anode needle is mounted in the connecting groove, and can not be effectively cooled, and also has no technical scheme for cooling anode needle. In addition, the anode needle is fixed in the connecting groove through threads, special tools are needed for installation in the production and maintenance processes, so that the disassembly and assembly processes are complicated, and in the use process or the transportation process of a user, the loosening phenomenon can occur in the threaded connection in the working environment of high temperature and high vibration, so that the normal use of the electric flame stove is influenced. Meanwhile, the electrode discharge effect separates oxygen molecules in the air, and the oxygen molecules are recombined to form ozone molecules, so that the human body is injured due to the fact that the ozone density is too high. Aiming at the technical problems in the field of electric flame stoves, the utility model discloses an electric flame stove which is stable in electrode needle, high in heat efficiency, capable of preventing heat of a stove head from affecting electronic elements and preventing ozone from damaging human bodies through technical transformation.
