Description

Technical Field

[0001] The utility model relates to the technical field of stoves, in particular to an electrode needle assembly and a gas stove. Background Art

[0002] The electrode needle is a key component in the burner of a gas stove, commonly known as the ignition needle. This component can emit a high-voltage and high-frequency electric arc, which can ignite the gas mixture, thereby causing the gas at all the fire holes on the burner of the gas stove to produce visible light combustion.

[0003] Since the gas has static pressure in the gas mixing chamber, the gas will be sprayed to more than 2.5 mm at the moment of ejection. Therefore, if the distance between the electrode needle head and the gas fire outlet is less than 2.5 mm, the electric arc and the gas will never cross, which will cause the gas to fail to be ignited and the gas stove cannot be ignited successfully. Due to the energy problem of the electric arc, the extension length of the electric arc is limited. Therefore, when the distance between the electrode needle head and the gas fire outlet is greater than 6 mm, the electric arc of the electrode needle is difficult to lead to the fire outlet, and it is difficult to cross the gas, and the gas cannot be ignited. Therefore, in order to achieve the purpose of igniting the gas at the fire outlet by the electrode needle discharge, it is necessary to ensure the position stability of the electrode needle so that the distance between the discharge head of the electrode needle and the gas fire outlet is stably between 2.5 mm and 6 mm.

[0004] In order to ensure the position stability of the electrode needle, patent CN218645614U discloses an ignition needle structure for a stove, which includes a burner, an ignition needle (electrode needle), a mounting cover and an elastic member; an ignition needle seat is provided on the burner, a mounting socket is provided on the ignition needle seat, and the inner wall of the mounting socket protrudes inward to form a positioning step; a positioning protrusion protruding outward is provided at the middle and lower part of the ignition needle, the middle and lower part of the ignition needle is inserted into the mounting socket and the outer wall of the ignition needle and the inner wall of the mounting socket are gap-matched, and the positioning protrusion rests on the positioning step; the mounting cover is provided on the ignition needle seat and the lower part of the mounting cover is inserted into the mounting socket, there is a gap between the lower part of the mounting cover and the upper part of the positioning protrusion, the middle and upper part of the ignition needle passes through the through hole, a through hole is provided on the mounting cover, and the outer wall of the ignition needle and the inner wall of the through hole are gap-matched; the elastic member is placed in the mounting socket and is located between the positioning protrusion and the lower part of the mounting cover.

[0005] Although the above-mentioned ignition needle structure can ensure the position stability of the ignition needle, the tail of the ignition needle is usually connected to a wire. During the installation process of the above-mentioned ignition needle structure, the wire at the tail of the ignition needle must first be passed through the installation socket from top to bottom, and then the ignition needle must be inserted into the installation socket. Since the wire is usually long, in order to improve efficiency and simplify the operation process, the installer often pulls the wire to the bottom at one time to drive the ignition needle to automatically insert into the installation socket. The ignition needle is usually a porcelain body. During the process of being driven by the wire to automatically insert into the installation socket, it will be subjected to the rapid downward pulling force of the wire, thereby hitting the positioning step on the inner wall of the installation socket, and it is very easy to be broken by the impact force. Utility Model Content

[0006] The purpose of the utility model is to provide an electrode needle assembly and a gas stove, so as to alleviate the technical problem existing in the prior art that during the installation process of the electrode needle on the existing gas stove, it is necessary to first pass the wire at the tail of the electrode needle through the installation socket of the ignition needle seat, and then insert the electrode needle into the installation socket, and in order to improve efficiency and simplify the operation process during operation, the installer often pulls the wire to the bottom at one time, causing the porcelain electrode needle to be subjected to the rapid downward pulling force of the wire and hit the positioning step on the inner wall of the installation socket, thereby being subjected to impact force and posing a risk of rupture.

[0007] In a first aspect, the utility model provides an electrode needle assembly, comprising an electrode needle, a seat body, an elastic member and a fixing member;

[0008] The electrode needle is provided with a first boss, the base body is provided with a fixing hole, the fixing hole is provided with a second boss, the electrode needle is inserted into the fixing hole and there is a gap between the first boss and the second boss, the elastic member is provided in the gap, and the two sides of the elastic member are respectively connected to the first boss and the second boss;

[0010] In an optional embodiment, the seat body includes a top and a bottom, and the fixing hole is provided between the top and the bottom of the seat body;

[0011] The electrode needle comprises a top portion and a tail portion, the top portion of the electrode needle is located above the top portion of the seat body, and the first boss is located below the second boss.

[0012] In an optional embodiment, the fixing member is located below the bottom of the base, and the electrode needle is fixedly connected to the bottom of the base via the fixing member.

[0013] In an optional embodiment, the fixing member is provided with a mounting hole corresponding to the fixing hole, the electrode needle is inserted into the mounting hole, and the side of the first boss facing away from the second boss abuts against the side of the fixing member facing the bottom of the seat body.

[0014] In an optional embodiment, a fastening hole is further provided on the fixing member, a fastening member is provided in the fastening hole, and the fixing member is fixedly connected to the bottom of the seat body via the fastening member.

[0015] In an optional embodiment, a through gap for the electrode needle to pass through is provided between the mounting hole and one of the side edges of the fixing member.

[0016] In an optional embodiment, a gap is provided between the first boss and the mutually facing side walls of the fixing hole, and a gap is provided between the second boss and the mutually facing side walls of the electrode needle.

[0017] In an optional embodiment, a gap between the first boss and the mutually facing side walls of the fixing hole, and a gap between the second boss and the mutually facing side walls of the electrode needle are both no greater than 5 mm.

[0018] In an optional embodiment, the interval between the first boss and the second boss is not less than one quarter of the length of the electrode needle.

[0019] In a second aspect, the utility model provides a gas stove, comprising the electrode needle assembly described in any one of the aforementioned embodiments.

[0020] The electrode needle assembly provided by the utility model includes an electrode needle, a seat, an elastic member and a fixing member; the electrode needle is provided with a first boss, the seat is provided with a fixing hole, a second boss is provided in the fixing hole, the electrode needle is inserted into the fixing hole and there is a gap between the first boss and the second boss, the elastic member is provided in the gap, and the two sides of the elastic member are respectively connected to the first boss and the second boss; the electrode needle is fixedly connected to the seat through the fixing member. The electrode needle in the electrode needle assembly provided by the utility model may also include a tail, and the tail is connected to a wire, and correspondingly, the end of the electrode needle away from the wire is its head. When installing the electrode needle in the electrode needle assembly, in order to prevent the wire from interfering with the installation process of the electrode needle, the elastic member can be first sleeved outside the electrode needle and positioned between the head of the electrode needle and the first boss, and then the head of the electrode needle is first inserted into the fixing hole on the seat body. As the first boss on the electrode needle gradually approaches the second boss in the fixing hole, the elastic member will also gradually approach the second boss. When the interval between the first boss and the second boss is less than the original length of the elastic member, the elastic member will be squeezed between the first boss and the second boss and exert a reverse thrust on the electrode needle, thereby buffering the installation process of the electrode needle to prevent the first boss of the electrode needle and the second boss in the fixing hole from colliding with each other. Therefore, even if the installer pushes the electrode needle into the fixing hole at one time in order to improve efficiency and simplify the operation process during the installation of the electrode needle, the elastic member between the first boss and the second boss will exert a reverse thrust on the electrode needle, thereby buffering the installation process of the electrode needle and effectively preventing the electrode needle from colliding with the second boss in the fixing hole and breaking. When the electrode needle is pushed into place in the fixing hole, the fixing piece is used to fix the electrode needle to the seat body to ensure the installation stability of the electrode needle, and the installation process of the electrode needle is completed. In addition, compared with the existing electrode needle installation process, during the installation process of the electrode needle in the electrode needle assembly provided by the utility model, the head of the electrode needle first enters the fixing hole of the seat body. When the electrode needle is pushed into place in the fixing hole, the fixing piece is used to fix the electrode needle to the seat body to realize the entire installation process of the electrode needle. This process does not require the wire at the tail of the electrode needle to pass through the fixing hole of the seat body, which can shorten the manual threading time and improve the installation efficiency of the electrode needle.

[0021] Compared with the prior art, the electrode needle assembly provided by the utility model can buffer the process of the electrode needle drilling into the fixing hole by the elastic force of the elastic member by arranging an elastic member between the first boss and the second boss, thereby preventing the electrode needle from impacting the second boss and effectively reducing the risk of the electrode needle breaking. In addition, during the installation process, the electrode needle in the electrode needle assembly provided by the utility model first enters the fixing hole of the seat body with its head, and there is no need to pass the wire at the tail of the electrode needle through the fixing hole, which can effectively shorten the manual threading time and improve the installation efficiency of the electrode needle.

[0022] The gas stove provided by the utility model comprises the electrode needle assembly, so the gas stove provided by the utility model has the same beneficial effects as the electrode needle assembly. BRIEF DESCRIPTION OF THE DRAWINGS

[0034] In order to make the purpose, technical scheme and advantages of the embodiments of the utility model clearer, the technical scheme in the embodiments of the utility model will be clearly and completely described below in conjunction with the drawings in the embodiments of the utility model. Obviously, the described embodiments are part of the embodiments of the utility model, not all of the embodiments. Generally, the components of the embodiments of the utility model described and shown in the drawings here can be arranged and designed in various different configurations.

[0035] Therefore, the following detailed description of the embodiments of the present invention provided in the accompanying drawings is not intended to limit the scope of the present invention to be protected, but merely represents selected embodiments of the present invention. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0036] In conjunction with the accompanying drawings, some embodiments of the present invention are described in detail below. In the absence of conflict, the following embodiments and features in the embodiments can be combined with each other.

[0037] Example:

[0038] like Figure 1-Figure 9 As shown, the electrode needle assembly provided in this embodiment includes an electrode needle 1, a seat body 2, an elastic member 3 and a fixing member 4; a first boss 10 is provided on the electrode needle 1, a fixing hole 20 is provided on the seat body 2, a second boss 200 is provided in the fixing hole 20, the electrode needle 1 is inserted into the fixing hole 20 and there is a gap between the first boss 10 and the second boss 200, the elastic member 3 is provided in the gap, and both sides of the elastic member 3 are respectively connected to the first boss 10 and the second boss 200; the electrode needle 1 is fixedly connected to the seat body 2 through the fixing member 4.

[0039] The electrode needle assembly provided in this embodiment can be applied to the burner of a gas stove, such as Figure 1 and Figure 2 As shown, the burner may further include a small fire cover 5, a large fire cover 6 and a gas mixing structure 7 with a gas mixture cavity formed therein, the gas mixing structure 7 is arranged above the base 2, the large fire cover 6 is an annular structure and is arranged above the gas mixing structure 7, and the small fire cover 5 is arranged in the inner ring space of the large fire cover 6. A nozzle may also be installed on the base 2, and the nozzle is correspondingly connected to the gas mixture cavity inside the gas mixing structure 7, and both the large fire cover 6 and the small fire cover 5 are provided with fire holes, and each fire hole is correspondingly connected to the gas mixture cavity.

[0040] When the burner is used for cooking, the gas can be sprayed into the mixed gas cavity through the nozzle, and then flow to the fire hole through the mixed gas cavity. In the electrode needle assembly provided in this embodiment, one end of the electrode needle 1 is a head 11, and the other end is a tail 12. The tail 12 of the electrode needle 1 is connected to a wire, and the head 11 passes through the fixing hole 20 on the base 2 and extends to one side of the fire hole. The head 11 of the electrode needle 1 is used for discharge to ignite the gas at the fire hole.

[0041] When the electrode needle 1 in the electrode needle assembly needs to be assembled on the base 2, in order to prevent the wire from interfering with the installation process of the electrode needle 1, the elastic member 3 such as a spring or a rubber sleeve can be firstly sleeved on the outside of the electrode needle 1 and positioned between the head 11 of the electrode needle 1 and the first boss 10, and then the head 11 of the electrode needle 1 is firstly entered into the fixing hole 20 on the base 2. As the first boss 10 on the electrode needle 1 gradually approaches the second boss 200 in the fixing hole 20, the elastic member 3 will also gradually approach the second boss 200. When the interval between the first boss 10 and the second boss 200 is smaller than the original length of the elastic member 3, the elastic member 3 will be squeezed between the first boss 10 and the second boss 200 and exert a reverse thrust on the electrode needle 1, thereby buffering the installation process of the electrode needle 1 to prevent the first boss 10 of the electrode needle 1 and the second boss 200 in the fixing hole 20 from colliding with each other.

[0042] Therefore, even if the installer pushes the electrode needle 1 into the fixing hole 20 at one time in order to improve efficiency and simplify the operation process during the installation of the electrode needle 1, the elastic member 3 between the first boss 10 and the second boss 200 will also exert a reverse thrust on the electrode needle 1, thereby buffering the installation process of the electrode needle 1 and effectively preventing the electrode needle 1 from colliding with the second boss 200 in the fixing hole 20 and causing it to break.

[0043] After the electrode needle 1 is pushed into place in the fixing hole 20 , the fixing member 4 is used to fix the electrode needle 1 and the base 2 to ensure the installation stability of the electrode needle 1 . At this point, the installation process of the electrode needle 1 is completed.

[0044] It should be noted that when the electrode needle 1 is fixedly connected to the base body 2 through the fixing member 4, the elastic member 3 between the first boss 10 and the second boss 200 can be in a compressed energy storage state. At this time, the electrode needle 1 will always be subjected to the reverse thrust of the elastic member 3 and stably located in the fixing hole 20, and will not shake at will in the fixing hole 20. Therefore, when the elastic member 3 is in a compressed energy storage state, the installation stability of the electrode needle 1 can be effectively guaranteed, thereby effectively ensuring the discharge distance of the head 11 of the electrode needle 1. Specifically, the distance between the head 11 of the electrode needle 1 and the gas ignition hole can be stably located between 2.5 mm and 6 mm, which can meet the demand of the electrode needle 1 to discharge and ignite the gas at the ignition hole.

[0045] In addition, compared with the existing electrode needle installation process, during the installation process of the electrode needle 1 in the electrode needle assembly provided in this embodiment, the head 11 first enters the fixing hole 20 of the seat body 2. After the electrode needle 1 is pushed into place in the fixing hole 20, the fixing member 4 is used to fix the electrode needle 1 and the seat body 2 to complete the entire installation process of the electrode needle 1. This process does not require the wire of the tail 12 of the electrode needle 1 to pass through the fixing hole 20 of the seat body 2, which can shorten the manual threading time and improve the installation efficiency of the electrode needle 1.

[0046] Compared with the prior art, the electrode needle assembly provided in this embodiment can buffer the process of the electrode needle 1 drilling into the fixing hole 20 by the elastic force of the elastic member 3 by arranging the elastic member 3 between the first boss 10 and the second boss 200, thereby preventing the electrode needle 1 from generating an impact with the second boss 200, and effectively reducing the risk of the electrode needle 1 breaking. In addition, during the installation process, the head 11 of the electrode needle 1 in the electrode needle assembly provided in this embodiment first enters the fixing hole 20 of the seat body 2, and there is no need to pass the wire of the tail 12 of the electrode needle 1 through the fixing hole 20, which can effectively shorten the manual threading time and improve the installation efficiency of the electrode needle 1.

[0047] In practical applications, the burner nozzle is usually arranged on the base body 2, and the large fire cover 6, the small fire cover 5 and the gas mixing structure 7 are all arranged above the base body 2. Therefore, in order to make the head 11 of the electrode needle 1 extend to the fire hole of the large fire cover 6 and the fire hole of the small fire cover 5, as shown in FIG. Figure 7 , Figure 8 and Fig. 9 As shown, in this embodiment, the seat body 2 preferably includes a top and a bottom, and the fixing hole 20 is provided between the top and the bottom of the seat body 2; Figure 2 , Figure 3 and Figure 4 As shown, the electrode needle 1 includes a head portion 11 and a tail portion 12 , the head portion 11 of the electrode needle 1 is located above the top of the base body 2 , and the first boss 10 is located below the second boss 200 .

[0048] like Figure 2 As shown, the fixing member 4 is located below the bottom of the base body 2 , and the electrode needle 1 is fixedly connected to the bottom of the base body 2 via the fixing member 4 .

[0049] When the fixing part 4 is arranged below the bottom of the seat body 2, it can effectively prevent liquids such as oil and water from dripping onto the fixing part 4 during cooking or cleaning, thereby preventing the connection between the fixing part 4 and the electrode needle 1 and the connection between the electrode needle 1 and the seat body 2 from rusting and becoming difficult to disassemble.

[0050] It should be noted that the ignition needle structure for stoves disclosed in the existing patent CN218645614U utilizes the lower part of the mounting cover to be inserted between the mounting socket on the ignition needle seat and the ignition needle to fix the position of the ignition needle. The mounting cover disclosed therein is located at the top of the ignition needle seat, and the top of the ignition needle seat is in an environment of high and low temperature changes for a long time and is subjected to the impact of an oil-water mixture for a long time. Rust is very easy to form between the mounting cover and the mounting socket and between the mounting cover and the ignition needle, which makes it difficult to disassemble the ignition needle during after-sales maintenance, increasing the difficulty of maintenance work.

[0051] In the electrode needle assembly provided in this embodiment, the fixing member 4 is located below the bottom of the base body 2, and the base body 2 can be used to shield the fixing member 4, effectively preventing the oil-water mixture from dripping on the fixing member 4 and causing rust.

[0052] It should also be noted that in the above-mentioned existing ignition pin structure for stoves, in order to ensure the reinforcement stability of the ignition pin by the mounting cover, it is usually made of metal or alloy material. In addition, since the mounting cover has a high requirement for anti-corrosion, the above-mentioned mounting cover is usually made of copper material in actual application, and copper material will greatly increase the cost.

[0053] Since the fixing member 4 in the electrode needle assembly provided in this embodiment is installed below the bottom of the base body 2, the fixing member 4 in this embodiment has a lower requirement for anti-corrosion and does not need to be made of expensive copper material.

[0054] In addition, in the ignition needle structure for stoves disclosed in the existing patent CN218645614U, the accuracy of the installation position of the ignition needle is determined by the size of the positioning step in the mounting socket on the ignition needle seat and the positioning protrusion on the ignition needle, and the positioning step in the mounting socket is formed by mechanical processing, and the processing depth is difficult to control and the shape of the tool used for processing the hole is also difficult to control, resulting in the drawings requiring the side wall of the positioning step to be processed into a plane, but the side wall of the positioning step after actual processing often has an inclination, and the drawings require the depth of the positioning step in the mounting socket to be 3 mm, but after actual processing, there is often an error of 2-4 mm. Based on this, the sizes of the positioning steps in the above-mentioned ignition needle structure vary greatly, resulting in poor positioning accuracy of the ignition needle, and it is still difficult to meet the discharge distance requirements of the ignition needle.

[0055] In the electrode needle assembly provided in this embodiment, the accuracy of the installation position of the electrode needle 1 is determined by the connection position between the fixing member 4 and the base body 2. When processing and manufacturing the electrode needle assembly, the bottom of the base body 2 can be regarded as the reference plane. As long as the processing accuracy of the fixing member 4 meets the requirements and the fixing member 4 accurately fixes the electrode needle 1 on the above-mentioned reference plane (the fixing member 4 is stably connected to the base body 2), the fixing member 4 can be used to accurately and stably limit the installation position of the electrode needle 1. At this time, even if there is an error in the processing accuracy of the second boss 200 in the fixing hole 20, it will not affect the installation position accuracy of the electrode needle 1. At the same time, under the energy storage effect of the elastic member 3, the installation stability of the electrode needle 1 in the fixing hole 20 can also be effectively guaranteed.

[0056] Therefore, the electrode needle assembly provided in this embodiment can also effectively ensure the installation position accuracy of the electrode needle 1 by utilizing the cooperation between the fixing member 4 and the base body 2 .

[0057] like Figure 5 and Figure 6 As shown, the fixing member 4 is provided with a mounting hole 40 corresponding to the fixing hole 20 , the electrode needle 1 is inserted into the mounting hole 40 , and the side of the first boss 10 facing away from the second boss 200 abuts against the side of the fixing member 4 facing the bottom of the seat body 2 .

[0058] When a mounting hole 40 is provided on the fixing member 4, the electrode needle 1 can also be limited by cooperating with the fixing member 4 on the side around the mounting hole 40 and the side of the first boss 10 facing away from the second boss 200. When the fixing member 4 is fixedly connected to the base body 2, the fixing member 4 can effectively prevent the electrode needle 1 from withdrawing from the fixing hole 20 under the reverse thrust of the elastic member 3.

[0059] like Figure 5 and Figure 6 As shown, the fixing member 4 is further provided with a fastening hole 41 , in which a fastening member 8 is provided, and the fixing member 4 is fixedly connected to the bottom of the seat body 2 via the fastening member 8 .

[0060] The fastening hole 41 on the fixing member 4 is used to provide an installation position for the fastener 8. In order to effectively ensure the connection stability between the fixing frame and the base body 2, in this embodiment, the fastener 8 is preferably a screw, and correspondingly, the fastening hole 41 on the fixing member 4 is a threaded hole.

[0061] It should also be noted that, by providing a fastening hole 41 on the fixing member 4, this embodiment can make the connection between the fastener 8 and the base body 2 away from the mounting hole 40, so that the connection between the fastener 8 and the base body 2 will not be located directly below the fixing hole 20. Even if liquids such as water and oil flow into the fixing hole 20 during the cooking process, the above liquid will not flow along the fixing hole 20 to the connection between the fastener 8 and the base body 2, further effectively avoiding rust at the connection between the fixing member 4 and the base body 2.

[0062] Further, such as Figure 5 and Figure 6 As shown, a through notch 42 for the electrode needle 1 to pass through is provided between the mounting hole 40 and one of the side edges of the fixing member 4 .

[0063] The through notch 42 allows the electrode needle 1 to enter the mounting hole 40 from the side of the fixing member 4, rather than only entering the mounting hole 40 of the fixing member 4 along the axial direction of the mounting hole 40. For example, when installing the electrode needle 1, the elastic member 3 can be first sleeved on the outside of the electrode needle 1, and then the electrode needle 1 can be inserted from bottom to top into the fixing hole 20 on the seat body 2, and then the fixing member 4 can be attached to the bottom of the bottom of the seat body 2, and the through notch 42 of the fixing member 4 can be located on the side of the electrode needle 1 exposed outside the fixing hole 20. At this time, the height of the through notch 42 of the fixing member 4 from the ground must be less than the height of the first boss 10 from the ground, and then the fixing member 4 can be pushed in the direction close to the electrode needle 1, so that the electrode needle 1 enters the mounting hole 40 of the fixing member 4 through the through notch 42. When the electrode needle 1 enters the mounting hole 40 of the fixing member 4, the elastic member 3 releases energy to push the electrode needle 1 to move closer to the fixing member 4, so that the side of the first boss 10 on the electrode needle 1 facing away from the second boss 200 is firmly abutted against the fixing member 4 on the side of the mounting hole 40. Finally, the fastener 8 can be passed through the fastening hole 41 of the fixing member 4 and fixedly connected to the base body 2. At this time, under the limiting action of the fixing member 4, the electrode needle 1 can be stably located in the fixing hole 20.

[0064] It can be seen that the through notch 42 makes the installation of the fixing member 4 more flexible, which can effectively improve the installation and removal flexibility of the electrode needle assembly.

[0065] Since the electrode needle assembly provided in this embodiment is provided with a fastening hole 41 on the fixing part 4 and a fastener 8 in the fastening hole 41, it can effectively prevent the liquid from flowing along the fixing hole 20 to the connection between the fastener 8 and the base body 2, and thus can effectively prevent the connection between the fastener 8 and the base body 2 from rusting. Therefore, liquid can enter the fixing hole 20 on the base body 2, and there is no need to adopt an interference fit installation method between the fixing hole 20 and the electrode needle 1.

[0066] Based on this, in this embodiment, preferably, a gap is provided between the first boss 10 and the side walls of the fixing hole 20 facing each other, and a gap is provided between the second boss 200 and the side walls of the electrode needle 1 facing each other.

[0067] The gap between the first boss 10 and the fixing hole 20 and the gap between the second boss 200 and the electrode needle 1 can effectively improve the convenience of the installation and removal process of the electrode needle 1 in the fixing hole 20 .

[0068] Furthermore, in this embodiment, preferably, the gap between the first boss 10 and the mutually facing side walls of the fixing hole 20, and the gap between the second boss 200 and the mutually facing side walls of the electrode needle 1, are both no greater than 5 mm.

[0069] When the above two gaps are not greater than 5 mm, it can not only ensure the convenience of the electrode needle 1 during installation and removal, but also prevent excessive accumulation of oil stains due to excessive gaps.

[0070] In this embodiment, the interval between the first boss 10 and the second boss 200 is not less than a quarter of the length of the electrode needle 1 .

[0071] The larger the interval between the first boss 10 and the second boss 200, the more secure the verticality of the electrode needle 1 in the fixing hole 20, and correspondingly, the more the discharge distance between the head 11 of the electrode needle 1 and the fire hole meets the requirements. Therefore, in this embodiment, it is preferred that the interval between the first boss 10 and the second boss 200 is not less than one-fourth of the length of the electrode needle 1.

[0072] This embodiment also provides a gas stove, which includes the above-mentioned electrode needle assembly. Therefore, the gas stove provided by this embodiment and the above-mentioned electrode needle assembly can solve the same technical problems and achieve the same technical effects, which will not be described in detail here.
