Description

Technical Field

[0001] The utility model specifically relates to a furnace head which is resistant to ionizing radiation. Background Art

[0002] A plasma stove is a new type of stove that utilizes the characteristics of plasma, uses high voltage electricity to break through the air to form thermal plasma, converts electrical energy into thermal energy, and ultimately obtains a thermal plasma beam of ideal length and function, generating a thermal plasma beam with flame-like characteristics to heat the pot for cooking.

[0003] The stove heads of plasma stoves currently on the market have the following defects: the discharge electrode inside the stove head ionizes the air after discharge and the ionizing radiation is not well shielded, which causes harm to the human body during long-term use.

[0004] For example, the patent with the authorization announcement number CN212339329U discloses an ionizing radiation-proof plasma stove, including a base, a stove head, and an electric control unit, wherein the stove head includes a plurality of discharge electrodes exposed from the top of the base and a transformer module arranged below the discharge electrode, the transformer module includes a mounting shell and a transformer circuit unit arranged in the mounting shell, the transformer circuit unit is electrically connected to the electric control unit and the discharge electrode; the stove head also includes a cylindrical stove head protection ring protruding from the top of the base and surrounding the discharge electrode, the stove head protection ring is made of metal and is provided with a first grounding fast connector; the mounting shell or the base is provided with a second grounding fast connector connected to the protective grounding wire. The utility model plasma stove can achieve a good ionizing radiation shielding effect by setting the pot-supporting component on the stove head into a cylindrical stove head protection ring, which is made of metal and combined with the bottom of the pot to enclose the ionizing radiation generated in the discharge electrode area in a closed space. However, the high-temperature resistant insulating plate under the electrode does not have the effect of shielding electromagnetic waves, so the electromagnetic waves are absorbed by the circuit and converted into heat energy, causing the local temperature of the electronic components to rise. Therefore, the electromagnetic waves will burn out the electronic components in the circuit; in addition, if the iron pot body above the protective circle leaves the protective circle, the electromagnetic waves will also radiate outward and affect the human body close to the stove body.

[0005] Therefore, the above patent cannot solve the problem of electromagnetic wave radiation. Utility Model Content

[0023] Discharge occurs between the electrode needle 5 and the metal flamethrower 11 used for striking the arc, generating ionizing electromagnetic wave radiation. For the conductor in the circuit below the furnace head, the conductor can both absorb and reflect electromagnetic wave energy. When the electromagnetic wave passes through the conductor, the free electrons in the conductor will vibrate under the action of the electromagnetic wave. The vibration of the free electrons will consume the energy of the electromagnetic wave, causing the electromagnetic wave to be absorbed. After the electromagnetic wave energy in the conductor is absorbed, it will be converted into heat energy, causing the local temperature of the conductor to rise. Therefore, the electromagnetic wave will burn out the electronic components in the circuit.

[0024] Therefore, in this embodiment, the furnace head top plate 1, the furnace head ring 2, the furnace head bottom plate 3 and multiple flame-spraying tubes 11 are all made of metal and are all connected to the ground wire, forming a cover that absorbs electromagnetic waves, enclosing the electromagnetic wave radiation generated by the discharge of multiple electrode needles 5 in a closed space, and absorbing the electromagnetic waves and converting them into heat energy.

[0026] In the next embodiment, the upper end of the electrode needle 5 extends upward, and the lower end thereof is installed in the lower end of the corresponding ceramic tube 4. The closest distance between the upper end of the electrode needle 5 and the flame-spraying tube 11 is greater than 5 mm.

[0027] In the next embodiment, at least one guide groove 41 is provided on the tube wall at the upper end of the ceramic tube 4, connecting the burner head and the inside of the ceramic tube 4; after the gas absorbs the heat from the burner head top plate 1, the burner head ring 2 and the burner head bottom plate 3, it enters the ceramic tube 4 through the guide groove 41, and the electrode needle 5 discharges and ionizes the gas to form a high-temperature plasma, and finally the plasma is ejected out of the flamethrower tube 11 under the action of the gas force.

[0028] In the next embodiment, the furnace head bottom plate 3 is also equipped with a fan for sucking gas to provide sufficient gas for the furnace head.

[0029] An electric flame cooker comprises the above-mentioned burner head which is resistant to ionizing radiation.

[0030] It is obvious to those skilled in the art that the present invention is not limited to the details of the exemplary embodiments described above, and that the present invention can be implemented in other specific forms without departing from the spirit or basic features of the present invention. Therefore, no matter from which point of view, the embodiments should be regarded as exemplary and non-restrictive, and the scope of the present invention is defined by the appended claims rather than the above description, and it is intended that all changes falling within the meaning and scope of the equivalent elements of the claims are included in the present invention.
