Description

Technical Field

[0001] This invention relates to the field of stove technology, and in particular to a burner assembly and an electric stove. Background Technology

[0002] Currently, most household kitchens use gas stoves for heating. These stoves are supplied with gas via gas cylinders or gas pipes. Gas cylinder supply presents challenges due to high operating costs and the inconvenience of gas replacement. Gas pipe supply presents difficulties in installation and requires specific kitchen layouts, limiting its usability. Summary of the Invention

[0003] Therefore, it is necessary to provide a convenient, high-performance, and safe burner assembly and electric stove to address the above problems.

[0004] A burner assembly includes: a housing assembly having a receiving cavity, the housing assembly having a plurality of first insertion holes and a plurality of second insertion holes, the plurality of first insertion holes and the plurality of second insertion holes communicating with the receiving cavity, the plurality of first insertion holes and the plurality of second insertion holes being arranged opposite to each other; a plasma assembly including a plurality of plasma needles, the plurality of plasma needles being disposed on the housing assembly by sequentially passing through the second insertion holes and the first insertion holes; and an electrical connection assembly located outside the receiving cavity of the housing assembly, the portion of the plasma assembly extending outside the receiving cavity via the first insertion holes being electrically connected to the electrical connection assembly.

[0005] The burner assembly disclosed in this application generates thermal plasma by discharging and breaking down the air at the high-voltage end of the plasma assembly during operation. This thermal plasma heats the pot body. The plasma assembly itself is also heated when operating externally. As the heat from the plasma assembly is transferred away from the discharge end, it passes through the receiving cavity, where it is released. After passing through the receiving cavity, the portion extending from the first insertion hole carries a small amount of heat, which will not affect the electrical connection assembly, thus improving stability during use and extending service life. The plasma passing through the first and second insertion holes allows the plasma needle to be stably positioned on the housing assembly, exhibiting good stability.

[0006] In one embodiment, the housing assembly includes a bracket and an insulating protective member. The bracket has a groove, the bottom of which has a first insertion hole, and the groove wall has an opening communicating with the groove. The insulating protective member covers the top of the groove, and the insulating protective member and the bracket enclose the receiving cavity. The insulating protective member has a second insertion hole corresponding to the first insertion hole.

[0007] The aforementioned insulating protective cover of the furnace head assembly is installed on the groove of the bracket, thereby forming a receiving cavity by the insulating protective cover and the bracket enclosing the groove. A portion of the plasma assembly passes through the second insertion hole on the insulating protective cover, the receiving cavity, and the first insertion hole, and is positioned on the bracket. The plasma head of the plasma needle is on one side of the insulating protective cover and located outside the receiving cavity. The support rod portion of the plasma needle, connected to the plasma head, is located outside the receiving cavity and on the same side as the plasma head. A portion of the support rod is located inside the cavity, and another portion is located on the other side of the bracket and connected to the electrical connection assembly. Therefore, when the heat from the plasma assembly is transferred away from the discharge end, it passes through the receiving cavity, and the heat is released within the receiving cavity. Simultaneously, an opening is provided on the side wall of the groove of the bracket, allowing the heat transferred from the plasma head to the support rod portion to dissipate to the outside through the opening communicating with the groove, preventing the bracket from deforming due to heat. Therefore, the above design improves the heat resistance of the bracket, enhances its structural strength, and extends its service life.

[0008] In one embodiment, the number of openings is multiple, and the multiple openings are spaced apart on the groove wall of the groove. The above-described burner assembly further specifies that: multiple openings are spaced apart on the support groove wall, thereby further enhancing the heat dissipation efficiency of the internal cavity of the support, improving the heat resistance stability of the support, and ensuring the structural strength of the support.

[0009] In one embodiment, the opening includes a first opening and a second opening, which are alternately arranged on the groove wall of the groove.

[0010] The aforementioned burner assembly further specifies that the support has staggered first and second openings on its groove wall, which helps to extend the heat dissipation airflow of the support and thus prolong the heat exchange time within the accommodating cavity. Furthermore, this structural design improves heat dissipation efficiency while being simpler in structure, facilitating manufacturing and production, and contributing to cost savings.

[0011] In one embodiment, the burner assembly further includes a heat dissipation device connected to the bracket and disposed corresponding to the opening.

[0012] The aforementioned burner assembly bracket is also connected to a heat dissipation device. The heat dissipation device is set in accordance with the opening, which helps to increase the air flow speed in the accommodating cavity, improve heat dissipation performance, better protect the structural strength of the bracket, and improve the safety performance of the burner assembly.

[0013] In one embodiment, the electrical connection assembly includes a connector and a plurality of capacitors, one end of each of the plurality of capacitors being connected to the connector and the other end of each of the plurality of capacitors being connected to a plurality of plasma needles.

[0014] By connecting multiple plasma needles to multiple capacitors, and simultaneously connecting the other ends of each capacitor to a connector, high-voltage electrical energy is stably transmitted through the connector to each capacitor, and then through the capacitors to the multiple plasma needles, exciting the high-voltage ends of the plasma needles to discharge and break down the air to form thermal plasma. Using multiple capacitors improves the stability of high-voltage transmission and prevents the failure of a single capacitor from causing the entire plasma assembly to fail. Therefore, the connection method between the plasma assembly and the electrical connection assembly described above is simpler in structure, more manufacturable, and safer and more reliable.

[0015] In one embodiment, the burner assembly further includes a plurality of seals located between the plasma needle and the wall of the second insertion hole, the seals being used to seal the gap between the plasma needle and the wall of the second insertion hole.

[0016] The aforementioned furnace head assembly further specifies that by sealing the gap between the second insertion hole of the insulating protective component and the support rod of the plasma needle using a sealing element, it further prevents hot plasma air generated outside the accommodating cavity from entering the accommodating cavity through the pores of the insulating protective component, and prevents the entering hot air from further affecting the heat resistance performance of the support. Therefore, the above-mentioned configuration can improve the heat resistance performance of the support and help extend its service life.

[0017] Optionally, the sealing element is a flexible element, which is detachably disposed on the second insertion hole. The sealing element is provided with a through hole that can communicate with the second insertion hole. After the plasma needle passes through the second insertion hole and the through hole, the plasma needle is sealed and connected to the second insertion hole.

[0018] The aforementioned furnace head assembly further specifies that the gap between the second insertion hole of the insulating protective component and the support rod of the plasma needle is sealed by a flexible sealant, such as a silicone, rubber, plastic, or any other heat-resistant polymer component. Using a flexible sealant improves the airtightness between the insulating protective layer and the plasma needle, and is simple and convenient to manufacture, thus saving costs.

[0019] In one embodiment, the bottom of the groove is provided with a plurality of protective structures, which are vertically arranged on the bottom of the groove, and the plurality of protective structures are respectively arranged around the periphery of the plurality of first insertion holes.

[0020] In the aforementioned burner assembly, the bottom of the groove is provided with multiple annular protective structures. The protective structures are located on the outer periphery of the first insertion hole. The protective structures are raised annular grooves. The above structure can prevent adjacent plasma components from interacting, avoid arcing, and provide safety performance for the burner assembly.

[0021] In one embodiment, the protective structure includes a plurality of protective structures arranged radially spaced along the first insertion hole.

[0022] The aforementioned burner assembly further specifies that: multiple protective structures are provided on the outer periphery of the first insertion hole, that is, multiple annular protrusions and annular grooves are radially distributed on the outer periphery of the first insertion hole to further prevent arcing and further improve the safety performance of the burner assembly.

[0023] The protective structure includes at least one first protective structure and multiple second protective structures. The plasma assembly also includes an ignition needle, which passes through the second insertion hole and the first insertion hole in sequence and is disposed on the housing assembly. The first protective structure is disposed around the outer periphery of the ignition needle, and the second protective structure is disposed around the outer periphery of the plasma needle. The height of the first protective structure relative to the bottom of the tank is greater than the height of the second protective structure relative to the bottom of the tank.

[0024] The aforementioned furnace head assembly further specifies that: a first protective structure is provided around the ignition needle in the plasma assembly, and a second protective structure is provided around the plasma needle. The height of the first protective structure is greater than the height of the second protective structure. Because the ignition needle has a stronger ability to break down air through discharge than other plasma needles, a relatively taller first protective structure is provided around the ignition needle to create an effective barrier between the ignition needle and adjacent plasma needles, thus better preventing arcing.

[0025] In one embodiment, the plasma assembly includes at least a first plasma module and a second plasma module. The first plasma module includes at least one first plasma needle, and the second plasma module includes a plurality of second plasma needles. The height of the end of the first plasma module away from the housing assembly relative to the housing assembly is greater than or less than the height of the end of the second plasma module away from the housing assembly relative to the housing assembly.

[0026] The aforementioned burner assembly further specifies that plasma modules at different heights are respectively installed on the bottom of the support groove of the housing assembly, wherein the height of the first plasma module relative to the bottom of the groove differs from the height of the second plasma module relative to the bottom of the groove. When the cookware is in use, the module at a higher height from the bottom of the groove is closer to the cookware and more easily interacts with it, causing high-pressure air breakdown. Since the heating effect can be controlled by adjusting the power of the high-voltage component at different distances, controllable heating is achieved. For example, the plasma module closer to the cookware can be activated first to achieve low-heat heating, while increasing the power can activate all plasma modules to achieve high-heat heating. Therefore, the above structure can produce two different heat efficiencies for heating the cookware, which can meet the heating efficiency requirements of electric stoves in different cooking scenarios. It is highly flexible, convenient to use, and the aforementioned burner assembly is simple to manufacture and easy to produce.

[0027] Optionally, the height of the first plasma module relative to the bottom of the support groove is greater than the height of the second plasma module relative to the bottom of the support groove. Therefore, the distance between the first plasma module and the external cookware is less than the distance between the second plasma module and the cookware. Thus, the above structure can generate two different heat efficiencies for heating the cookware, adapting to the heating efficiency requirements of the electric stove in different cooking scenarios. It is highly flexible, convenient to use, and the aforementioned burner assembly is simple to manufacture and easy to produce.

[0028] Optionally, the first plasma module is positioned at the center of the support, and the second plasma module is positioned around the outer periphery of the first plasma module.

[0029] In one embodiment, the first plasma needle includes a first plasma head and a first support rod, one end of the first support rod being connected to the first plasma head, and the end of the first support rod away from the first plasma head passing through the first insertion hole and connected to the electrical connection assembly; the second plasma needle includes a second plasma head and a second support rod, one end of the second support rod being connected to the second plasma head, and the end of the second support rod away from the second plasma head passing through the first insertion hole and connected to the electrical connection assembly; the plasma assembly further includes a third plasma module, the third plasma module including a plurality of third plasma needles, each third plasma needle including a third plasma head and a third support rod, one end of the third support rod being connected to the third plasma head, and the end of the third support rod away from the third plasma head passing through the first insertion hole and connected to the electrical connection assembly; the diameter of the third plasma head is larger than the diameter of the first plasma head and / or the second plasma head.

[0030] The aforementioned furnace head assembly also includes a third plasma module, wherein the third plasma head of the third plasma module is larger than the first plasma head, or the third plasma head of the third plasma module is larger than the second plasma head. By setting plasma heads of different sizes, the aforementioned furnace head assembly can be configured with plasma components of different heating powers, thereby improving the heating flexibility of the furnace head assembly.

[0031] In one embodiment, the height of the first plasma head relative to the housing assembly is greater than the height of the second plasma head relative to the housing assembly.

[0032] In one embodiment, the height of the second plasma head relative to the housing assembly is greater than the height of the third plasma head relative to the housing assembly.

[0033] In the aforementioned burner assembly, the height of the first plasma head relative to the housing assembly is greater than the height of the second plasma head relative to the housing assembly, and / or the height of the second plasma head relative to the housing assembly is greater than the height of the third plasma head relative to the housing assembly. In this case, the burner assembly contains plasma modules with inconsistent heights and plasma head sizes, thus enabling the burner assembly to generate various heat effects with different power levels, further enhancing the versatility of its cooking functions.

[0034] An electric stove includes: a stove body; a burner assembly as described in any one of the preceding claims, the burner assembly being disposed on the stove body; and a high-voltage assembly, the high-voltage assembly being electrically connected to the electrical connection assembly.

[0035] The present invention also discloses an electric stove, wherein the stove body is provided with any of the aforementioned burner components. By incorporating the aforementioned burner components, the electric stove of the present invention possesses all the performance characteristics of the aforementioned burner components.

[0036] Optionally, the high-voltage assembly includes at least a housing, a magnetic core assembly, and an insulating sleeve assembly. The housing has a mounting cavity, and the magnetic core assembly is disposed within the mounting cavity. The insulating sleeve assembly includes a first insulating sleeve and a second insulating sleeve, on which a primary coil and a secondary coil are wound, respectively. The first and second insulating sleeves are respectively fitted onto the magnetic core assembly. The first insulating sleeve is thinned to ensure that the primary coil does not break down while improving cooling performance. The core is designed with an angle within the housing, making the spatial structure of the high-voltage assembly more conducive to thinning. Furthermore, the reduced space between the high-voltage assembly's housing, magnetic core assembly, and insulating sleeve assembly reduces the amount of adhesive used, resulting in better cooling performance of the high-voltage assembly.

[0060] To better understand the above-mentioned objectives, features, and advantages of the present invention, the present invention will be further described in detail below with reference to the accompanying drawings and specific embodiments. It should be noted that, unless otherwise specified, the embodiments and features described in these embodiments can be combined with each other.

[0061] Many specific details are set forth in the following description in order to provide a full understanding of the invention. However, the invention may also be practiced in other ways different from those described herein, and therefore the scope of protection of the invention is not limited to the specific embodiments disclosed below.

[0062] The following description, with reference to the accompanying drawings, describes some embodiments of the burner assembly and electric stove of the present invention.

[0063] like Figure 1 , Figure 2 , Figure 8 As shown, this embodiment discloses a burner assembly, including: a housing assembly 1, the housing assembly 1 having a receiving cavity 101, and the housing assembly 1 having a plurality of first insertion holes 102 and a plurality of second insertion holes 201, the plurality of first insertion holes 102 and the plurality of second insertion holes 201 communicating with the receiving cavity 101, and the plurality of first insertion holes 102 and the plurality of second insertion holes 201 being arranged opposite to each other; a plasma assembly 3, the plasma assembly 3 including a plurality of plasma needles 31, the plurality of plasma needles 31 being disposed on the housing assembly 1 through the second insertion holes 201 and the first insertion holes 102 in sequence; and an electrical connection assembly 4, the electrical connection assembly 4 being located outside the receiving cavity 101 of the housing assembly 1, the portion of the plasma assembly 3 extending outside the receiving cavity 101 via the first insertion holes 102 being electrically connected to the electrical connection assembly 4.

[0064] The burner assembly disclosed in this application discharges and breaks down the air at the high-voltage end of the plasma assembly 3 to form thermal plasma during operation. This thermal plasma heats the pot body. The plasma assembly 3 is also heated when operating externally. As the heat from the plasma assembly 3 is transferred away from the discharge end, it passes through the receiving cavity 101, where it is released. After passing through the receiving cavity 101, the portion extending from the first insertion hole 102 carries a small amount of heat, which will not affect the electrical connection assembly 4, thus improving stability during use and extending service life. The plasma passing through the first insertion hole 102 and the second insertion hole 201 allows the plasma needle 31 to be stably mounted on the housing assembly 1, exhibiting good stability.

[0065] like Figure 1 and Figure 2 As shown, in addition to the features of the above embodiments, this embodiment further defines: the housing assembly 1 includes a bracket 11 and an insulating protective member 12. The bracket 11 is provided with a groove, a first insertion hole 102 is provided on the bottom of the groove, and an opening communicating with the groove is provided on the groove wall; the insulating protective member 12 is provided on the top of the groove, and the insulating protective member 12 and the bracket 11 form an accommodating cavity 101. The insulating protective member 12 is provided with a second insertion hole 201 corresponding to the first insertion hole 102.

[0066] The aforementioned furnace head assembly insulating protective component 12 covers the groove of the support 11, thereby forming a receiving cavity 101 by the insulating protective component 12 and the support 11 surrounding the groove. A portion of the plasma assembly 3 passes through the second insertion hole 201, the receiving cavity 101, and the first insertion hole 102 on the insulating protective component 12 and is positioned on the support 11. The plasma head of the plasma needle is on one side of the insulating protective component 12 and located outside the receiving cavity 101. The support rod portion of the plasma needle connected to the plasma head is located outside the receiving cavity and on the same side as the plasma head, while a portion of the support rod is located inside the cavity. Another portion of the support rod is located on the other side of the support 11 and connected to the electrical connection component 4. Therefore, when the heat from the plasma assembly 3 is transferred away from the discharge end, it passes through the receiving cavity 101, and the heat is released within the receiving cavity 101. Simultaneously, an opening is provided on the side wall of the groove of the support 11, allowing the heat transferred from the plasma head to the support rod portion to dissipate to the outside through the opening communicating with the groove, preventing the support 11 from deforming due to heat. Therefore, the above design can improve the heat resistance of the bracket 11, and enhance the structural strength and service life of the bracket 11.

[0067] like Figure 4 , Figure 5 As shown, in this embodiment, there are multiple openings, which are spaced apart on the groove wall.

[0068] The aforementioned burner assembly further specifies that: multiple openings are spaced apart on the groove wall of the support 11, thereby further enhancing the heat dissipation efficiency of the internal cavity 101 of the support 11, improving the heat resistance stability of the support 11, and ensuring the structural strength of the support 11.

[0069] like Figure 5 As shown, in this embodiment, the opening includes a first opening 103 and a second opening 104, which are staggered on the groove wall.

[0070] The aforementioned burner assembly further specifies that the support 11 has staggered first openings 103 and second openings 104 on its groove wall, which helps to extend the heat dissipation airflow of the support 11 and thus prolong the heat exchange time within the accommodating cavity 101. Furthermore, this structural design improves heat dissipation efficiency while being simpler in structure, facilitating manufacturing and production, and helping to save costs.

[0071] like Figure 4 As shown, in this embodiment, the burner assembly also includes a heat dissipation device 6, which is connected to the bracket 11 and is configured to correspond to the opening.

[0072] The support 11 of the aforementioned burner assembly is also connected to a heat dissipation device 6. The heat dissipation device 6 is arranged in accordance with the opening, which helps to increase the air flow speed in the accommodating cavity 101, improve heat dissipation performance, better protect the structural strength of the support 11, and improve the safety performance of the burner assembly.

[0073] like Figure 2 , Figure 3 , Figure 8 As shown, in this embodiment, the electrical connection assembly 4 includes a connector 41 and a plurality of capacitors 42. One end of each of the plurality of capacitors 42 is connected to the connector 41, and the other end of each of the plurality of capacitors 42 is connected to a plurality of plasma needles 31.

[0074] By connecting multiple plasma needles to multiple capacitors 42, and connecting the other ends of each capacitor 42 to connectors 41, high-voltage electrical energy is stably transmitted via connectors 41 to each capacitor 42, and then via capacitors 42 to the multiple plasma needles, stimulating the high-voltage ends of the plasma needles to discharge and break down the air to form thermal plasma. By using multiple capacitors 42, the stability of high-voltage transmission can be improved, preventing the failure of a single capacitor from causing a complete failure of the plasma assembly 3. Therefore, the connection method between the plasma assembly 3 and the electrical connection assembly 4 described above is simpler in structure, more manufacturable, and safer and more reliable.

[0075] like Figure 2 , Figure 6As shown, in this embodiment, the burner assembly also includes a sealing element 5. There are multiple sealing elements 5, which are located between the plasma needle and the hole wall of the second insertion hole 201. The sealing element 5 is used to seal the gap between the plasma needle and the hole wall of the second insertion hole 201.

[0076] The aforementioned burner assembly further defines how the gap between the second insertion hole 201 of the insulating protective member 12 and the support rod of the plasma needle is sealed by the sealing member 5, thereby further preventing hot plasma air generated outside the accommodating cavity 101 from entering the accommodating cavity 101 through the pores of the insulating protective member 12 and causing the entering hot air to further affect the heat resistance of the support 11. Therefore, the above-mentioned arrangement can improve the heat resistance of the support 11 and help extend the service life of the support 11.

[0077] Optionally, the sealing element 5 is a flexible element. The sealing element 5 is detachably disposed on the second insertion hole 201. The sealing element 5 is provided with a through hole 501 that can communicate with the second insertion hole 201. After the plasma needle passes through the second insertion hole 201 and the through hole 501, the plasma needle is sealed and connected to the second insertion hole 201.

[0078] The aforementioned furnace head assembly further specifies that the gap between the second insertion hole 201 of the insulating protective element 12 and the support rod of the plasma needle is sealed by a flexible sealant, such as a silicone, rubber, plastic, or any other heat-resistant polymer. Using a flexible sealant improves the airtightness between the insulating protective layer 12 and the plasma needle, and is simple and convenient to manufacture, thus saving costs.

[0079] like Figure 2 , Figure 5 , Figure 8 As shown, in this embodiment, a plurality of protective structures 7 are provided on the bottom of the groove. The protective structures 7 are vertically arranged on the bottom of the groove, and the plurality of protective structures 7 are respectively arranged around the periphery of the plurality of first insertion holes 102.

[0080] In the aforementioned burner assembly, the bottom of the groove is provided with multiple annular protective structures 7. The protective structures are located on the outer periphery of the first insertion hole 102. The protective structure 7 is a raised annular groove. The above structure can prevent adjacent plasma components from interacting, avoid arcing, and provide safety performance for the burner assembly.

[0081] like Figure 2 , Figure 5 , Figure 8 As shown, in this embodiment, the protective structure 7 includes a plurality of protective structures 7, which are arranged radially at intervals along the first insertion hole 102.

[0082] The aforementioned burner assembly further specifies that: multiple protective structures 7 are provided on the outer periphery of the first insertion hole 102, that is, multiple annular protrusions and annular grooves are radially distributed on the outer periphery of the first insertion hole 102 to further prevent arcing and further improve the safety performance of the burner assembly.

[0083] like Figure 2 , Figure 5 , Figure 8 As shown, in this embodiment, the protective structure 7 includes at least one first protective structure 71 and a plurality of second protective structures 72. The plasma assembly 3 also includes an ignition needle 32, which passes through the second insertion hole 201 and the first insertion hole 102 in sequence and is disposed on the housing assembly 1. The first protective structure 71 is disposed around the outer periphery of the ignition needle 32, and the second protective structure 72 is disposed around the outer periphery of the plasma needle 31. The height of the first protective structure 71 relative to the bottom of the tank is greater than the height of the second protective structure 72 relative to the bottom of the tank.

[0084] The aforementioned furnace head assembly further specifies that: a first protective structure 71 is provided around the ignition needle 32 in the plasma assembly 3, and a second protective structure 72 is provided around the plasma needle 31. The height of the first protective structure 71 is greater than the height of the second protective structure 72. Because the ignition needle 32 has a stronger ability to break down air through discharge than other plasma needles 3, the relatively taller first protective structure 71 is provided around the ignition needle 32 to form an effective barrier between the ignition needle 32 and adjacent plasma needles 31, thus better preventing arcing.

[0085] like Figure 1 , Figure 3 As shown, in this embodiment, the plasma assembly 3 includes at least a first plasma module 301 and a second plasma module 302. The first plasma module 301 includes at least one first plasma needle 311, and the second plasma module 302 includes a plurality of second plasma needles 321. The height of the end of the first plasma module 301 away from the housing assembly 1 relative to the housing assembly 1 is greater than or less than the height of the end of the second plasma module 302 away from the housing assembly 1 relative to the housing assembly 1.

[0086] The aforementioned burner assembly further specifies that plasma modules at different heights are respectively installed on the bottom of the support 11 of the housing assembly 1, wherein the height of the first plasma module 301 relative to the bottom of the support 11 differs from the height of the second plasma module 302 relative to the bottom of the support 11. When the cookware is in use, the module at a higher height from the bottom of the slot is closer to the cookware and more easily interacts with it to achieve high-pressure air breakdown. Since the heating effect can be controlled by adjusting the power of the high-voltage component, controllable heating is achieved. For example, the plasma module closer to the cookware can be activated first to achieve low-heat heating, while increasing the power can activate all plasma modules to achieve high-heat heating. Therefore, the above structure can produce two different heat efficiencies for heating the cookware, which can meet the heating efficiency requirements of electric stoves in different cooking scenarios. It is highly flexible, convenient to use, and the aforementioned burner assembly is simple to manufacture and easy to produce.

[0087] Optionally, the height of the first plasma module 301 relative to the bottom of the support 11 groove is greater than the height of the second plasma module 302 relative to the bottom of the support 11 groove. Therefore, the distance between the first plasma module 301 and the external cookware is less than the distance between the second plasma module 302 and the cookware. Thus, the above structure can generate two different heat efficiencies for heating the cookware, adapting to the heating efficiency requirements of the electric stove in different cooking scenarios. It is highly flexible, convenient to use, and the aforementioned burner assembly is simple to manufacture and easy to produce.

[0088] Optionally, such as Figure 1 As shown, the first plasma module 301 is located at the center of the support 11, and the second plasma module 302 is arranged around the outer periphery of the first plasma module 301.

[0089] like Figure 3As shown, in this embodiment, the first plasma needle 311 includes a first plasma head 3111 and a first support rod 3112.
