Abstract
Description
Technical Field
[0001] This application relates to the technical field of gas stoves, and more particularly, to a burner assembly and a gas stove. Background Art
[0002] Currently, during the use of household gas stoves on the market, a high ignition failure rate is the main reason for the poor user experience. The main reason for the high ignition failure rate is the poor discharge at the head of the ignition needle. The problems that cause poor discharge at the head of the ignition needle, in addition to low battery power and leakage, the most important reason is that the ignition needle shakes, resulting in unstable ignition distance. The ignition distance is either too far or too close, greatly reducing the discharge effect of the ignition needle. Summary of the Utility Model
[0003] The purpose of this application is to provide a burner assembly and a gas stove for at least one technical problem involved in the background art.
[0004] To achieve the above object, this application adopts the following technical solutions:
[0005] One aspect of this application provides a burner assembly, including a burner body, an ignition needle, a buffer member, and a fixing member. An ignition needle mounting hole and a fixing member mounting hole that communicate with each other are formed on the burner body. The axis of the ignition needle mounting hole intersects with the axis of the fixing member mounting hole. The fixing member is fitted with the fixing member mounting hole. The ignition needle and the buffer member are both mounted in the ignition needle mounting hole. In the ignition needle mounting hole, the fixing member, the buffer member, and the ignition needle are in pressure contact in sequence.
[0006] Optionally, the buffer member is a sleeve-like member, and the buffer member is sleeved on the ignition needle.
[0007] The beneficial effect of this technical solution is that in this way, the buffer member sleeved outside the ignition needle is not easily separated from between the fixing member and the ignition needle, improving the stability of the fixing member for fixing the ignition needle.
[0008] Optionally, a fixing groove is formed on the buffer member. The fixing groove is recessed inward from the outside of the buffer member and protrudes toward the inside of the buffer member. On the axis of the buffer member, the fixing groove extends from one end of the buffer member to the other end. The fixing member is in pressure contact with the buffer member at the fixing groove.
[0009] The beneficial effects of this technical solution are as follows: In this way, when the acting force of the fixing member acts on the buffer member, the position of the fixing groove is under pressure. Since the fixing groove protrudes inwardly towards the buffer member, the pressure between the fixing groove and the ignition needle is relatively large, thereby fixing the ignition needle more firmly within the buffer member. Moreover, the pressure of the fixing member acting on the position of the fixing groove will cause a certain deformation of the buffer member, thereby increasing the tightness of the contact between the buffer member and the ignition needle, and further improving the reliability of fixing the ignition needle. At the same time, by fixing the buffer member and the ignition needle simultaneously with the fixing member, the buffer member and the ignition needle can be firmly sleeved together, making it difficult for relative movement to occur between the buffer member and the ignition needle.
[0010] Optionally, a plurality of positioning blind holes are provided at the bottom of the fixing groove, and the positioning blind holes are arranged in the length direction of the fixing groove for cooperating with the end of the fixing member; and / or, the fixing member mounting hole is a threaded hole, and the fixing member is an externally threaded connecting member.
[0011] The beneficial effects of this technical solution are as follows: In this way, after adjusting the positions of the ignition needle and the fixing member, the end of the fixing member is made to cooperate with the corresponding positioning blind hole, which further limits the position of the fixing member, making it difficult for the buffer member to move on its axis, and thus it is not easy to have problems such as end-to-end discharge affecting ignition due to the distance between the end of the buffer member and the head of the ignition needle being too close. Moreover, the position of the fixing member can be adjusted by rotating the fixing member to achieve pressure contact between the fixing member and the buffer member, or to achieve separation between the fixing member and the buffer member so as to adjust the position of the buffer member and / or the ignition needle. At the same time, the installation height of the buffer member and the ignition needle can be conveniently adjusted to adapt to different burners, and the installation method is simple.
[0012] Optionally, the axis of the ignition needle mounting hole is perpendicular to the axis of the fixing member mounting hole.
[0013] The beneficial effects of this technical solution are as follows: In this way, the acting force of the fixing member acts more concentratedly on the buffer member, obtaining a better effect of fixing the buffer member and the ignition needle.
[0014] Optionally, the buffer member is a metal sheath.
[0015] Optionally, the buffer member is a copper sheath.
[0016] The beneficial effects of this technical solution are as follows: Since the copper sheath is relatively soft among metal sheaths, the acting force between the copper sheath and the ignition needle can be appropriately increased, making the burner not easily damaged. Moreover, sleeving a copper sheath outside the ignition needle can help the head of the ignition needle maintain sufficient electric field strength, enabling spark discharge to be successfully generated even at a relatively low charge accumulation level, and improving the success rate of directional ignition of the ignition needle.
[0017] Another aspect of the present application provides a gas stove, which includes a burner and the stove head assembly provided by the present application, and the burner is installed on the stove head body.
[0018] Optionally, ignition holes are formed in the burner. The ignition needle includes an ignition needle body and a head. The head is fixed to the top end of the ignition needle body. The buffer member is sleeved on the ignition needle body, and the distance between the top end of the buffer member and the head is greater than the distance between the head and the ignition hole.
[0019] Optionally, the gas stove provided by the present application further includes a thermocouple and a connecting member. An electric couple mounting hole and a connecting hole are further formed on the stove head body. The electric couple mounting hole and the connecting hole communicate with each other, and the axis of the electric couple mounting hole intersects with the axis of the connecting hole. The thermocouple is installed in the electric couple mounting hole, and the connecting member is in threaded fit with the connecting hole, and the connecting member is in pressure contact with the thermocouple.
[0020] The beneficial effect of this technical solution is that in this way, the thermocouple can be fixed in the electric couple mounting hole through the connecting member, so that the thermocouple is not prone to shaking. When it is necessary to adjust the position of the thermocouple or replace the thermocouple, the connecting member can be rotated to separate the connecting member from the thermocouple, thereby realizing the adjustment of the position of the thermocouple.
[0021] The technical solution provided by the present application can achieve at least one of the following beneficial effects:
[0022] For the stove head assembly and the gas stove provided by the present application, by the fixing member, the buffer member and the ignition needle being in pressure contact in sequence in the ignition needle mounting hole, the fixing of the position of the ignition needle by the fixing member is realized. During use, the ignition needle is not prone to shaking, and the ignition distance consistency is relatively high, thereby improving the success rate of ignition. At the same time, since the ignition needle body is generally a porcelain body, the buffer member is used to isolate the fixing member and the ignition needle, so that the ignition needle is not prone to breakage under the pressure of the buffer member, playing a role in protecting the ignition needle.

[0038] The technical solutions of the present application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are some, but not all, of the embodiments of the present application.

In addition, the terms "first", "second", and "third" are only used for descriptive purposes and cannot be construed as indicating or implying relative importance.
[0040] In the description of the present application, it should be noted that unless otherwise clearly specified and defined, the terms "installation", "connection", and "coupling" should be understood in a broad sense. For example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection or an indirect connection through an intermediate medium, and it can be the communication inside two components. For those of ordinary skill in the art, the specific meanings of the above terms in the present application can be understood according to specific circumstances.
[0041] As Figures 1 to 4 shown, one aspect of the present application provides a burner head assembly, including a burner head body 04, an ignition needle 09, a buffer member 07, and a fixing member 03. An ignition needle mounting hole 10 and a fixing member mounting hole 11 that communicate with each other are formed on the burner head body 04. The axis of the ignition needle mounting hole 10 intersects with the axis of the fixing member mounting hole 11. The fixing member 03 is engaged with the fixing member mounting hole 11. The ignition needle 09 and the buffer member 07 are both mounted in the ignition needle mounting hole 10. In the ignition needle mounting hole 10, the fixing member 03, the buffer member 07, and the ignition needle 09 are in pressure contact in sequence.
[0042] In the burner head assembly provided by the present application, by making the fixing member 03, the buffer member 07, and the ignition needle 09 in pressure contact in sequence in the ignition needle mounting hole 10, the fixing of the position of the ignition needle 09 by the fixing member 03 is realized. During use, the ignition needle 09 is not likely to shake, and the ignition distance consistency is relatively high, thereby improving the ignition success rate. At the same time, since the ignition needle body 06 is generally made of porcelain, the buffer member 07 is used to isolate the fixing member 03 and the ignition needle 09, so that the ignition needle 09 is not likely to be damaged under the pressure of the buffer member 07, playing a role in protecting the ignition needle 09.
[0043] Optionally, the buffer member 07 is a sleeve-shaped member, and the buffer member 07 is sleeved on the ignition needle 09. In this way, the buffer member 07 sleeved outside the ignition needle 09 is not likely to separate from between the fixing member 03 and the ignition needle 09, improving the stability of the fixing member 03 in fixing the ignition needle 09. Of course, the buffer member 07 can also be a sheet-shaped member.
[0044] Optionally, a fixing groove 14 is formed on the buffer member 07. The fixing groove 14 is recessed inward from the outer side of the buffer member 07 and protrudes inwardly from the inner side of the buffer member 07. On the axis of the buffer member 07, the fixing groove 14 extends from one end of the buffer member 07 to the other end. The fixing member 03 is in pressure contact with the buffer member 07 at the fixing groove 14. In this way, when the acting force of the fixing member 03 acts on the buffer member 07, the position of the fixing groove 14 is under pressure. Since the fixing groove 14 protrudes inwardly from the inner side of the buffer member 07, the pressure between the fixing groove 14 and the ignition pin 09 is relatively large, thereby fixing the ignition pin 09 more firmly within the buffer member 07. Moreover, the pressure of the fixing member 03 acting on the position of the fixing groove 14 causes a certain deformation of the buffer member 07, thereby increasing the tightness of the contact between the buffer member 07 and the ignition pin 09 and further improving the reliability of fixing the ignition pin 09. At the same time, by fixing the buffer member 07 and the ignition pin 09 simultaneously with the fixing member 03, the buffer member 07 and the ignition pin 09 can be firmly sleeved together, making it difficult for relative movement to occur between the buffer member 07 and the ignition pin 09.
[0045] Optionally, a plurality of positioning blind holes 15 are formed at the bottom of the fixing groove 14. The positioning blind holes 15 are arranged in the length direction of the fixing groove 14 and are used for cooperating with the end of the fixing member 03; and / or, the fixing member mounting hole 11 is a threaded hole, and the fixing member 03 is an external thread connecting member.
[0046] That is to say, in the embodiment of the present application, at least the following three implementation manners are included: The first implementation manner is that a plurality of positioning blind holes 15 are formed at the bottom of the fixing groove 14. The positioning blind holes 15 are arranged in the length direction of the fixing groove 14 and are used for cooperating with the end of the fixing member 03. The second implementation manner is that the fixing member mounting hole 11 is a threaded hole, and the fixing member 03 is an external thread connecting member. The third implementation manner is that a plurality of positioning blind holes 15 are formed at the bottom of the fixing groove 14. The positioning blind holes 15 are arranged in the length direction of the fixing groove 14 and are used for cooperating with the end of the fixing member 03, and the fixing member mounting hole 11 is a threaded hole, and the fixing member 03 is an external thread connecting member.
[0047] In this way, after adjusting the positions of the ignition needle 09 and the fixing member 03, the end of the fixing member 03 is fitted with the corresponding positioning blind hole 15, which further limits the position of the fixing member 03, making it difficult for the buffer member 07 to move along its axis. As a result, it is not easy to have the problem that the end-to-end discharge occurs due to the distance between the end of the buffer member 07 and the head of the ignition needle 09 being too close, which affects the ignition. Moreover, the position of the fixing member 03 can be adjusted by rotating the fixing member 03 to achieve the pressure contact between the fixing member 03 and the buffer member 07, or to achieve the separation between the fixing member 03 and the buffer member 07, thereby adjusting the position of the buffer member 07 and / or the ignition needle 09. At the same time, the installation heights of the buffer member 07 and the ignition needle 09 can be conveniently adjusted to adapt to different burners 08, and the installation method is simple. The external thread connecting member can be a screw or a bolt, etc. Of course, the fixing member 03 can also be a pin, and the pin is fixed by the interference fit between the pin and the fixing member installation hole 11.
[0048] Optionally, the axis of the ignition needle installation hole 10 is perpendicular to the axis of the fixing member installation hole 11. In this way, the acting force of the fixing member 03 is more concentrated on the buffer member 07, obtaining a better effect of fixing the buffer member 07 and the ignition needle 09.
[0049] Optionally, the buffer member 07 is a copper sheath. Since the copper sheath is relatively soft among metal sheaths, the acting force between the copper sheath and the ignition needle 09 can be appropriately increased, making the burner 08 not easily damaged. Moreover, sleeving the copper sheath outside the ignition needle 09 can help the head of the ignition needle 09 maintain sufficient electric field strength, so that spark discharge can be successfully generated even at a lower charge accumulation level, improving the success rate of the directional ignition of the ignition needle 09.
[0050] Another aspect of the present application provides a gas stove, including a burner 08 and the burner head assembly provided by the embodiments of the present application, and the burner 08 is installed on the burner head body 04.
[0051] The gas stove provided by the present application adopts the burner head assembly provided by the present application. By the fixing member 03, the buffer member 07 and the ignition needle 09 being in pressure contact in sequence in the ignition needle installation hole 10, the position of the ignition needle 09 is fixed by the fixing member 03. During use, the ignition needle 09 is not easy to shake, thereby improving the success rate of ignition. At the same time, since the body of the ignition needle 09 is generally a porcelain body, the buffer member 07 is used to isolate the fixing member 03 and the ignition needle 09, so that the ignition needle 09 is not easy to be damaged under the pressure of the buffer member, playing a role in protecting the ignition needle 09.
[0052] Optionally, an ignition hole 01 is formed on the burner 08. The ignition needle 09 includes an ignition needle body 06 and a head 02. The head 02 is fixed to the top end of the ignition needle body 06. The buffer 07 is sleeved on the ignition needle body 06. The distance between the top end of the buffer 07 and the head 02 is greater than the distance between the head 02 and the ignition hole 01. Preferably, the distance between the head 02 and the ignition hole 01 is 3-5 mm.
[0053] Optionally, the gas stove provided by the embodiment of the present application further includes a thermocouple 13 and a connecting piece 16. An electric couple installation hole 12 and a connection hole are further formed on the stove head body 04. The electric couple installation hole 12 and the connection hole communicate with each other, and the axis of the electric couple installation hole 12 intersects with the axis of the connection hole. The thermocouple 13 is installed in the electric couple installation hole 12. The connecting piece 16 is in threaded cooperation with the connection hole, and the connecting piece 16 is in pressure contact with the thermocouple 13. In this way, the thermocouple 13 can be fixed in the electric couple installation hole 12 through the connecting piece 16, so that the thermocouple 13 is not likely to shake. When it is necessary to adjust the position of the thermocouple 13 or replace the thermocouple 13, the connecting piece 16 can be rotated to separate the connecting piece 16 from the thermocouple 13, thereby realizing the adjustment of the position of the thermocouple 13.
[0054] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present application, rather than to limit them; although the present application has been described in detail with reference to the foregoing embodiments, those of ordinary skill in the art should understand that they can still modify the technical solutions described in the foregoing embodiments, or perform equivalent replacements on some or all of the technical features; and these modifications or replacements do not make the essence of the corresponding technical solutions deviate from the scope of the technical solutions of the embodiments of the present application.
