Description

Technical Field

[0001] This utility model relates to the field of electric flame stove technology, and in particular to an electrode cap, an electric flame stove burner head, and an electric flame stove. Background Technology

[0002] An electric flame stove, as the name suggests, is a type of open-flame stove that does not use chemical fuels; it can also be described as a device that ignites air. An electric flame stove generates a strong electric field between one or more pairs of electrodes by applying a high-voltage pulse power supply. This ionizes and heats the air flowing between the electrodes, transforming it into a high-temperature plasma flow that produces an electric flame similar to the visible flame of a gas stove, thus heating cookware.

[0003] Electric flame stoves, as a novel application of electric arc plasma, have many unique advantages, but due to the inherent characteristics of air plasma, they also have certain drawbacks, mainly:

[0004] On the one hand, when generating high-temperature plasma gas flow, the electric flame nozzle will have a very strong high voltage. If the user is not careful, they may be shocked or burned when their hand touches the relevant part, which poses a certain safety hazard during use.

[0005] On the other hand, the plasma gas stream generated by electric arc discharge contains ozone and nitrogen oxides of varying densities. Ozone is produced by the combination of oxygen atom free radicals at high temperatures, while nitrogen oxides are produced by the combination of nitrogen atom free radicals and oxygen atom free radicals at high temperatures to produce nitric oxide (NO). Some nitric oxide can then combine with other oxygen atom free radicals to generate nitrogen dioxide (NO2). Excessive emissions of ozone and nitrogen oxides pose a health hazard, and the "Ambient Air Quality Standard" (GB3095-2012) stipulates emission standards.

[0006] The plasma gas stream generated by the discharge has a very wide potential temperature range, from tens of degrees to tens of thousands of degrees. If left uncontrolled, it poses a risk of burning through cookware, and when the temperature reaches thousands of degrees, it easily generates ozone and nitrogen oxides in the air. Therefore, how to solve the problem of excessive ozone and nitrogen oxide emissions in existing electric flame stoves without significantly increasing research and development costs remains to be addressed.

[0007] In response, the inventor of this patent, drawing on experience, deeply considered the problems encountered in his work, reviewed a large amount of scientific research data and literature, and gradually conceived and designed this application through a novelty search to solve the relevant technical problems.

[0063] The electrode cap 1000, the electric flame stove burner head 2000, and the electric flame stove 3000 of this utility model embodiment are described in detail below with reference to the accompanying drawings.

[0064] Example 1

[0065] Reference Figures 1 to 3 , Figure 6 and Figure 7 As shown;

[0066] The electrode cap 1000 provided according to the embodiment of the present utility model includes a cap body 10, which is adapted to be fixed to the top of the electrode needle of the electric flame stove 3000 to isolate the high voltage generated by the electrode needle of the electric flame stove 3000, and the cap body 10 is made of insulating material, or its surface is provided with a layer of insulating material.

[0067] Based on the above, it is clear that this application is mainly used as an electrode cap 1000 in specific implementation.

[0068] Specifically, when applying this application, refer to Figure 6 and Figure 7 As shown, whether it is the conventionally used electric flame stove 3000 or the electric flame stove 3000 designed in this application, the electrode cap 1000 is designed to a suitable size and specification, and it is fixed to the top of the electrode needle of the electric flame stove 3000 so that it is located in the upper part of the flame tube 401 of the electric flame stove 3000. In this way, this application can be used easily.

[0069] Since the cap 1000 described in this application is made of insulating material or has an insulating material layer on its surface, it has good insulation performance. It can isolate the high voltage generated by the electrode needle of the electric flame stove 3000 upward and outward, so that the user's hands and other parts are not easily shocked or burned by the high voltage generated by the electrode needle of the electric flame stove 3000. Thus, when this application is used with the electric flame stove 3000, it can make the use safe and reliable, and can better reduce the safety hazards during use.

[0070] Furthermore, in a specific implementation, according to one embodiment of the present invention, the bottom of the cap 10 is provided with an insertion hole 101 facing upwards, and the insertion hole 101 is suitable for the top of the electrode needle of the electric flame stove 3000 to be detachably inserted.

[0071] Therefore, it is clear that in practical application, the top of the electrode needle of the electric flame stove 3000 is directly inserted into the insertion hole 101. In this way, the application can be easily fixed, making it less likely to fall off during use, and making it easy and effortless to disassemble.

[0072] Furthermore, in this technical solution, according to one embodiment of the present utility model, the cap body 10 is formed into an inverted cone-shaped structure, so that its outer diameter gradually increases from bottom to top.

[0073] Therefore, it is clear that by shaping the cap 10 into an inverted cone shape, with its outer diameter gradually increasing from bottom to top, the advantage of this design is that when the electric flame generated by the high voltage breakdown of the air by the electrode needle of the electric flame stove 3000 is emitted upward from the flame tube 401 of the electric flame stove 3000, the generated electric flame, when passing through the outer wall of the cap 10, will be refracted upward to the inner wall of the flame tube 401 of the electric flame stove 3000, and then reflected directly above the upper end face of the cap 10, so that a backflow zone is formed directly above the upper end face of the cap 10, making the shape of the generated electric flame just like the shape of a gas stove flame, which is very realistic and can bring a better user experience.

[0074] Furthermore, in a specific implementation, according to one embodiment of this utility model, the cap 10 is rutile and / or anatase doped with substances such as N and / or C.

[0075] It should be noted that rutile and / or anatase both contain a large amount of titanium dioxide (TiO2), which can decompose ozone (O3) and nitrogen oxides (NOx) through a photocatalytic reduction mechanism. x );

[0076] Under ultraviolet (UV) irradiation, electron-hole pairs are generated on the surface of titanium dioxide (TiO2), which in turn produce reactive oxygen species (such as OH and O2). - These reactive substances can react with ozone (O3), breaking it down into oxygen (O2). The chemical reaction is roughly as follows: O3 + photogenerated electrons → O2 + O2 - ;

[0077] Furthermore, titanium dioxide (TiO2) can oxidize nitric oxide (NO) and nitrogen dioxide (NO2) to nitrate (NO3) under ultraviolet light. -Harmless substances such as NO and OH. A typical reaction pathway is: NO + OH → HNO2 → NO3. - NO2 + cavitation → NO3 - This process has been widely applied to building coatings (such as "self-cleaning" concrete) to reduce urban NOx emissions. x pollute.

[0078] The aforementioned titanium dioxide (TiO2) requires ultraviolet light excitation (wavelength ≤387nm), but by doping with substances such as N and / or C, its response can be extended to visible light, allowing it to still decompose ozone (O3) and nitrogen oxides (NOx) under natural light irradiation. x The effect of ).

[0079] Furthermore, even in the absence of light, titanium dioxide (TiO2) retains its triggering activity at temperatures above 600 degrees Celsius, allowing it to directly catalyze the decomposition of ozone. The specific decomposition formula is: 2O3 + TiO2 TiO2,hν 3O2;

[0080] Furthermore, as an existing technology, anatase exhibits high catalytic activity. Due to its wide band gap and high photogenerated electron energy, its efficiency in reducing ozone (O3→O2) is remarkably high. Its abundant surface hydroxyl groups can promote the adsorption of ozone (O3) and intermediate products (such as O3... - Further decomposition of rutile, and as an existing technology, rutile has good thermal stability and strong resistance to sintering.

[0081] Therefore, in this application, when the cap 10 is made of rutile and anatase doped with N and / or C, that is, when the cap 10 is made of a nanocomposite of rutile and anatase doped with N and / or C, the mixed crystal phase can combine the advantages of both to achieve complementary advantages. Electrons in the conduction band of anatase can be transferred to the conduction band of rutile, which can prolong the carrier lifetime. Rutile absorbs low-energy photons, while anatase absorbs high-energy photons, which can improve the utilization rate of the entire spectrum. Moreover, rutile has good thermal stability and strong anti-sintering ability, which makes the cap 10 formed by the composite high in hardness and long in service life. Furthermore, according to experimental analysis, the ozone decomposition rate of the mixed phase titanium dioxide (TiO2) can be increased by 30% to 50% compared with that of the single crystal phase.

[0082] Thus, when the cap 10 described in this application is rutile and / or anatase doped with substances such as N and / or C, it effectively controls ozone (O3) and nitrogen oxides (NO). x The process involves decomposition to reduce the ozone (O3) and nitrogen oxides (NOx) produced by the electric flame stove 3000 during operation. x The emission levels are controlled to ensure that they do not exceed the standards, so that in practical application, this application is not only safe and reliable to use, but also environmentally friendly.

[0083] Furthermore, through the above-mentioned optimized design, the whole constituted by this application is highly practical and has a good effect in use.

[0084] Furthermore, in another embodiment of this invention, according to one embodiment of the present invention, the surface of the cap 10 is coated with a nano-scale titanium dioxide (TiO2) material coating doped with N and / or C and / or a nano-scale aluminum oxide (Al2O3) material coating doped with oxides of Ag, Mn and / or Co.

[0085] Thus, based on the description above regarding the cap body 10 being rutile and / or anatase doped with substances such as N and / or C, it can be understood that when a nano-scale titanium dioxide material coating doped with substances such as N and / or C is laminated onto the surface of the cap body 10, it will also contain a large amount of titanium dioxide (TiO2), enabling this application to achieve the same ozone (O3) and nitrogen oxide (NO) levels. x Decomposition effect.

[0086] Meanwhile, nanoscale aluminum oxide (Al2O3) coatings doped with Ag, Mn, and / or Co oxides contain a large amount of aluminum oxide (Al2O3). These Al2O3-related substances can act as a carrier to support Ag, Mn, and / or Co oxides, indirectly participating in ozone (O3) decomposition through the synergistic effect of the composite material. For example: 3O3 + MnO2 / Al2O3 → 3O2. This composite system is widely used in industrial waste gas treatment for degrading high concentrations of ozone (O3).

[0087] Furthermore, under high temperature conditions (such as 400-600℃), aluminum oxide (Al2O3) can decompose nitrogen oxides (NOx) through an adsorption-dissociation mechanism. x ).

[0088] Thus, when the surface of the cap 10 is coated with a nano-sized aluminum oxide (Al2O3) material doped with Ag, Mn and / or Co oxides, this application can still achieve the same ozone (O3) and nitrogen oxide (NO) emission levels. x Decomposition effect.

[0089] Example 2

[0090] Reference Figures 4 to 7 As shown;

[0091] According to an embodiment of the present invention, the electric flame stove burner head 2000 includes a burner head bottom plate 20, multiple anode electrode needles 30, a burner head top plate 40, a stove surround 50 for supporting cookware, and multiple electrode caps 1000 as described above.

[0092] The bottom surface of the stove base plate 20 is evenly provided with a plurality of hollow plug-in columns 201 that penetrate to its upper end surface; the stove top plate 40 is stacked and fixed on the stove base plate 20, and its upper end surface is evenly provided with a plurality of flame tubes 401 whose bottoms are connected to its lower end surface, and the plurality of flame tubes 401 are located directly above the plurality of hollow plug-in columns 201.

[0093] Furthermore, the lower ends of the multiple anode electrode needles 30 are correspondingly inserted into the multiple hollow plug-in posts 201, and the upper ends of the multiple anode electrode needles 30 extend into the multiple flame tubes 401; the multiple electrode caps 1000 are correspondingly fixed on the top of the multiple anode electrode needles 30 and are correspondingly limited in the upper part of the multiple flame tubes 401.

[0094] Based on this, the furnace enclosure 50 described in this application is placed on the furnace head top plate 40 and covers the plurality of flame tubes 401, with its height being slightly higher than the height of the plurality of flame tubes 401.

[0095] Therefore, it is clear that by installing the electric flame stove burner head 2000 described in this application onto the matching electric flame stove 3000 housing 80, and connecting the multiple anode electrode needles 30 to the electric flame generating device 90 installed inside the matching electric flame stove 3000 housing 80, and turning on the power supply of the matching electric flame stove 3000, this application can be driven to work, so that the multiple anode electrode needles 30 generate high voltage to ionize the air to form plasma or high-voltage electric arc to form an electric flame. In this way, it is possible to heat the food or other items contained in the pot supported on the stove enclosure 50.

[0096] The electric flame stove burner head 2000 with the structure described in this application has the following advantages:

[0097] On the one hand, the multiple flame tubes 401 provided cover the multiple anode electrode needles 30 and the electrode caps 1000 fixed on their tops, so that the multiple anode electrode needles 30 and the electrode caps 1000 fixed on their tops are well isolated and well protected, so that they are not easily touched by external objects, resulting in a long service life.

[0098] On the other hand, since the furnace enclosure 50 rests on the top plate 40 of the burner head and covers the multiple flame tubes 401, its height is slightly higher than the height of the multiple flame tubes 401. Therefore, when the cookware is placed on the furnace enclosure 50, its bottom is less likely to touch the multiple flame tubes 401. This ensures that the multiple flame tubes 401 are fully protected and safe to use, while the high-temperature electric flames emitted from their tops can be evenly sprayed onto the bottom surface of the cookware, resulting in good heating uniformity of the food contained in the cookware.

[0099] Furthermore, when the electric flame stove burner 2000 described in this application has multiple electrode caps 1000 as described in Embodiment 1, the electric flame stove burner 2000 provided in this application can also be used safely and can also decompose ozone (O3) and nitrogen oxides (NO). x The ability to reduce ozone (O3) and nitrogen oxides (NOx) produced during use. x The emission levels are controlled to ensure that they do not exceed the standards, so that they are safe, reliable and environmentally friendly in practical applications.

[0100] Furthermore, through the above-mentioned optimized design, the electric flame stove burner 2000 described in this application achieves good performance.

[0101] Furthermore, in a specific implementation, according to one embodiment of the present invention, the outer diameter of the furnace enclosure 50 gradually decreases from bottom to top, and a plurality of cookware support blocks 501 are uniformly protruding upward from the upper edge of the furnace enclosure 50.

[0102] Thus, it can be clearly stated that:

[0103] On the one hand, since the outer diameter of the furnace enclosure 50 gradually decreases from bottom to top, its upper part can be formed into a narrow opening. Therefore, it is better to prevent external water and oil stains from entering through the narrow opening at the top and contaminating the multiple flame tubes 401 and other structural components.

[0104] On the other hand, since a plurality of cookware support blocks 501 for supporting cookware are evenly protruding upward on the upper edge of the furnace enclosure 50, even if external air can enter the furnace enclosure 50 through the gaps between the plurality of cookware support blocks 501, it is easy to replenish and be ionized by high voltage so as to continuously generate electric flame.

[0105] Furthermore, through the above-mentioned optimized design, the overall performance of the electric flame stove burner 2000 described in this application can be effectively improved.

[0106] Furthermore, in a specific implementation, according to one embodiment of the present invention, this application in this embodiment also includes a plurality of cathode electrode needles 60;

[0107] The cathode electrode needles 60 are all formed into a spiral ring structure and are correspondingly fixed to the outer side of the anode electrode needles 30, so that there is a certain gap between them and the outer wall of the corresponding anode electrode needles 30, and a certain gap between them and the inner wall of the corresponding flame tubes 401. Furthermore, the height of their upper ends is equal to or slightly lower than the height of the electrode caps 1000.

[0108] In this regard, it is clear that traditional electric flame stove burners 2000 generally do not have multiple cathode electrode needles 60 individually provided. This is mainly to allow the tops of multiple flame tubes 401 to be used directly as cathode electrodes. In the improvement of this application, multiple cathode electrode needles 60 are provided, and they are all formed into a spiral ring structure and correspondingly fitted outside multiple anode electrode needles 30. Furthermore, the height of their upper ends is equal to or slightly lower than the height of multiple electrode caps 1000.

[0109] Therefore, in practical application of this application, the multiple anode electrode needles 30 and the cathode electrode needles 60 surrounding them can be designed coaxially, so that each set of anode electrode needles 30 and cathode electrode needles 60 can form a uniform electric field with each other, which can better limit the range of the electric field and minimize secondary discharge, making the application safer and more reliable to use.

[0110] Therefore, through the above-mentioned optimized design, the overall performance of the electric flame stove burner 2000 described in this application can be optimized.

[0111] Furthermore, in a specific implementation, according to one embodiment of the present invention, there is a certain gap between the outer wall of the electrode cap 1000 and the inner wall of the flame tube 401 covering it, so as to form an air flow channel 70, so that air can pass through and be ionized by high voltage to form an electric flame.

[0112] Example 3

[0113] Reference Figures 8 to 9 As shown;

[0114] According to an embodiment of the present utility model, the electric flame stove 3000 includes a housing 80 and an electric flame generating device 90 disposed on the housing 80, and also includes the electric flame stove burner 2000 as described above.

[0115] The upper surface of the housing 80 is provided with an installation port 801, the electric flame stove burner head 2000 is fitted into the installation port 801, and the multiple anode electrode needles 30 of the electric flame stove burner head 2000 are electrically connected to the electric flame generating device 90.

[0116] Therefore, as described in Embodiment 1 and Embodiment 2 above, the electric flame stove 3000 provided in this application also has the effects described in Embodiment 1 and Embodiment 2 above.

[0117] In short, the electric flame stove 3000 provided in this application is also safe to use in actual use and also has the ability to decompose ozone (O3) and nitrogen oxides (NOx). xThe ability to reduce ozone (O3) and nitrogen oxides (NOx) produced during use. x The emission levels are controlled to ensure that they do not exceed the standards, so that they are safe, reliable and environmentally friendly in practical applications.

[0118] It should be added that, in specific implementation, whether it is the above-mentioned embodiment 2 or embodiment 3, the inner diameter of the multiple flame-blowing tubes 401 provided in the electric flame stove burner 2000 and electric flame stove 3000 according to the present utility model embodiment is gradually decreasing from bottom to top. In this way, the electric flames emitted from the upper end of the multiple flame-blowing tubes 401 will be more elongated, resulting in a better heating effect on the bottom of the pot.

[0119] Other embodiments, etc., will not be described here.

[0120] In summary, the electrode cap 1000, electric flame stove burner head 2000, and electric flame stove 3000 provided in this application are safe to use in practice and are capable of decomposing ozone (O3) and nitrogen oxides (NOx). x The ability to reduce ozone (O3) and nitrogen oxides (NOx) produced during use. x The emission levels are controlled to ensure that they do not exceed the standards, so that the application is safe, reliable and environmentally friendly.
