DETAILED DESCRIPTION

[0026] For better understanding and implementation, the technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the accompanying drawings in the embodiments of the present invention.

[0027] In the description of the present invention, it should be noted that the terms "upper", "lower", "front", "back", "left", "right", "vertical", "horizontal", "top", "bottom", "inside" and "outside" etc. indicating directions or positional relationships are based on the directions or positional relationships shown in the accompanying drawings, and are only for the convenience of describing the present invention and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific direction, be constructed and operated in a specific direction, and therefore cannot be understood as a limitation on the present invention.

[0028] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as those commonly understood by those skilled in the art of the present invention. The terms used herein in the specification of the present invention are only for the purpose of describing specific embodiments and are not intended to limit the present invention.

[0029] See also Figure 1-Figure 5 The utility model discloses a burner head 10 assembly, including a burner head 10 and an ignition mechanism, and a positioning portion is provided on the burner head 10. The ignition mechanism includes an ignition needle 21 and a guide block 22. The ignition needle 21 is installed on the burner head 10, and the burner head 10 can move along the height direction of the burner head 10. The above-mentioned guide block 22 is arranged on the ignition needle 21, and a guiding portion, a first limiting portion 211 and a second limiting portion 212 are provided on the guide block 22. The guiding portion can slide and cooperate with the positioning portion when the ignition needle 21 moves, and the guiding portion can guide the positioning portion to slide to the first limiting portion 211 or the second limiting portion 212 and position and cooperate. Specifically, when the positioning portion is positioned and cooperated with the first limiting portion 211, the ignition needle 21 is located in the first position (see Figure 2), when the positioning portion and the second limiting portion 212 are positioned and matched, the ignition needle 21 is located at the second position (see Figure 1 ).

[0030] On the basis of the above structure, when using the burner head 10 assembly of the utility model, the burner head 10 assembly is installed on the stove, and the burner head 10 of the burner head 10 assembly is introduced through the gas pipe. When igniting, the fire cover ring is placed on the burner head 10. After the fire cover ring is lowered, it presses the ignition needle 21 to drive the ignition needle 21 to move downward. When the ignition needle 21 moves downward, the positioning part of the burner head 10 can slide with the guide part, and the guide part guides the positioning part to move to the first limit part 211, and cooperates with the first limit part 211 to limit the ignition needle 21. The ignition needle 21 can remain positioned in the first position. At this time, it means that the fire cover ring has been sealed in place, and the ignition needle 21 can start the ignition action.

[0031] When the fire cover ring is removed, the ignition needle 21 can move upward. At this time, the positioning portion on the burner head 10 slides with the guide portion of the guide block 22 to guide the positioning portion to move to the second limit portion 212 and limit the second limit portion 212, so that the ignition needle 21 is in the second position. At this time, it means that the fire cover ring is in the removed state and cannot be ignited.

[0032] Therefore, in the present application, the ignition needle 21 can move up and down, and the guide portion of the guide block 22 on the ignition needle 21 slides with the positioning portion on the burner head 10, and the positioning portion of the burner head 10 is limited by the first limit portion 211 or the second limit portion 212, so that the ignition needle 21 can be in the first position or the second position. In this way, the position of the ignition needle 21 can be used to indicate whether the fire cover ring is in place, so that ignition can be carried out after the fire cover ring is in place, which is safer to use.

[0033] It should be noted that the ignition needle 21 in this embodiment is an ignition structure used for stoves in the prior art. Its specific ignition structure and ignition principle belong to the prior art and are not the technical content to be protected in this application, and will not be described in detail here.

[0034] Furthermore, an arc guide groove 213 is provided on the guide block 22, and the positioning portion is slidably embedded in the arc guide groove 213. A first limiting recess is provided at one end of the arc guide groove 213, and a second limiting recess is provided at the other end of the arc guide groove 213. In this way, when the ignition needle 21 moves, the positioning portion of the burner head 10 can slide in the arc guide groove 213. Since the arc guide groove 213 has a certain curvature, the positioning portion can slide in the arc direction when the ignition needle 21 moves up and down, so that the positioning portion can move to the first limiting recess or the second limiting recess to achieve positioning.

[0035] Since the first limiting recess and the second limiting recess have a recessed structure, the positioning part can be located in the recessed structure after moving to the position, so as to prevent it from being separated from the first limiting recess or the second limiting recess. At the same time, the arc guide groove 213 is an arc structure, not a linear motion trajectory, so even if the ignition needle 21 is subjected to up and down forces, the arc guide structure can also limit the movement of the ignition needle 21 in the case of accidental collision, and the positioning part can only slide along the arc structure when the external force is large enough.

[0036] Based on this structure, the first limiting portion 211 is a first limiting recess provided at one end of the arc guide groove 213, and the second limiting portion 212 is a second limiting recess provided at the other end of the arc guide groove 213; the arc guide groove 213 is formed as a guide portion.

[0037] Of course, the above-mentioned guide part can also be implemented by a spiral guide groove or a plurality of tooth-shaped groove structures. In the case where the guide part is a spiral guide groove, the movement trajectory of the positioning part is a spiral structure, and the ignition needle 21 moves up and down, and the positioning part slides along the spiral structure and can also be guided by the spiral structure. When the guide part is a plurality of tooth-shaped groove structures, when the ignition needle 21 moves up and down, the positioning part can slide along the inclined surface of the tooth-shaped groove, and the two ends of the inclined surface of the tooth-shaped groove can be formed into a first limiting part 211 and a second limiting part 212.

[0038] More specifically, the above-mentioned arc guide grooves 213 are provided with two, the first limiting recess can be connected to one end of the two arc guide grooves 213, and the second limiting recess is connected to the other end of the two arc guide grooves 213. Based on this structure, the two ends of the arc guide grooves 213 on both sides are connected with the first limiting recess and the second limiting recess, so that a ring-shaped guiding track can be formed. When the ignition needle 21 moves up and down, the positioning part can slide along the arc guide groove 213 on one side, or along the arc guide groove 213 on the other side, and it can slide according to the force direction of the ignition needle 21. Compared with the single-sided arc guide groove 213, it is not affected by the force direction of the ignition needle 21, and the up and down process is smoother.

[0039] Furthermore, the positioning part is a spring sheet 23, one end of which is connected to the burner head 10, and the other end of which extends into the arc guide groove 213 and slides with the arc guide groove 213. The spring sheet 23 has a certain elasticity and can be stretched or contracted according to the arc track of the arc guide groove 213, so that the positioning part can slide more adaptively and reduce the possibility of getting stuck. After sliding to the first limiting part 211 or the second limiting part 212, it can have a certain tension under the action of its own elastic force, and the limiting and abutting effect is better.

[0040] Furthermore, the ignition mechanism also includes an elastic component 24, which is arranged below the guide block 22, and the guide block 22 can press the elastic component 24 when the ignition needle 21 moves downward, so that the elastic component 24 can provide an elastic stress, under the action of which the guide block 22 can be driven to move upward, thereby driving the ignition needle 21 to reset upward.

[0041] On the basis of the structure of setting the elastic component 24, the ignition needle 21 maintains an upward moving state under the action of the elastic stress of the elastic component 24, and the positioning part can slide to the lower second limiting part 212 after the movement of the guide part, and abut against the lower second limiting part 212. The ignition needle 21 can be maintained in the second position state under the action of the elastic stress and the second limiting part 212. At this time, the ignition needle 21 is in a non-ignition state.

[0042] When ignition is needed, the ignition needle 21 moves downward under the pressure of the fire cover ring. At this time, the ignition needle 21 moves downward, driving the guide block 22 to press the elastic component 24 downward. The elastic component 24 is compressed, and the positioning portion can guide the portion to slide downward and then slide to the upper first limit portion 211, and abut against the upper first limit portion 211. The ignition needle 21 can be maintained in the first position state, and the ignition needle 21 can start ignition.

[0043] More specifically, a retaining spring 211 can be installed at the bottom end of the ignition needle 21. The retaining spring 211 protrudes from the outer periphery of the ignition needle 21. The ignition needle 21 can slide relative to the retaining spring 211. The elastic component 24 is arranged between the retaining spring 211 and the guide block 22. In this way, after the ignition needle 21 moves downward, the ignition needle 21 drives the guide block 22 to move downward relative to the retaining spring 211, and the guide block 22 can press the elastic component 24, and the elastic component 24 can be compressed.

[0044] In order to prevent the retaining spring 211 from being pressed and sliding by the elastic component 24 when the guide block 22 presses, the retaining spring 211 can be relatively fixed to the furnace head 10, so that the assembly structure of the retaining spring 211 is stable, so that the elastic component 24 can be stably compressed and provide stable elastic stress.

[0045] Furthermore, specifically, the guide block 22 is mounted outside the ignition needle 21, and a limiting step is provided on the ignition needle 21, which abuts against the top of the guide block 22, so that the guide block 22 can maintain a stable assembly state under the elastic stress of the limiting step and the elastic component 24.

[0046] Specifically, a snap ring 212 is provided on the outside of the ignition needle 21, which abuts against the top of the guide block 22 and forms a limiting step, so that the guide block 22 can maintain a stable assembly state under the action of the snap ring 212, preventing the guide block 22 from sliding upward relative to the ignition needle 21 under the action of the elastic component 24.

[0047] Furthermore, the burner head 10 assembly also includes a fire cover ring, which can be covered on the burner head 10. The fire cover ring is used to press the ignition needle 21 after being covered on the burner head 10, so as to drive the ignition needle 21 to move downward.

[0048] When igniting, the fire cover ring is placed on the burner head 10. After the fire cover ring is lowered, it presses the ignition needle 21 to drive the ignition needle 21 to move downward. When the ignition needle 21 moves downward, the positioning part of the burner head 10 can slide with the guide part, and the guide part guides the positioning part to move to the first limit part 211, and the ignition needle 21 can be positioned in the first position. At this time, it means that the fire cover ring has been sealed in place and the ignition needle 21 can start the ignition action.

[0049] When the fire cover ring is removed, the ignition needle 21 can move upward. At this time, the positioning portion on the burner head 10 slides with the guide portion of the guide block 22 to guide the positioning portion to move to the second limit portion 212 and limit the second limit portion 212, so that the ignition needle 21 is in the second position. At this time, it means that the fire cover ring is in the removed state and cannot be ignited.

[0050] The present embodiment also provides a stove, including the above-mentioned burner head 10 assembly, which is installed on the stovetop of the stove. The structure, working principle and effect of the specific burner head 10 assembly used in the stove are the same as those of the above-mentioned burner head 10 assembly, and will not be described in detail here.

[0051] The technical means disclosed in the solution of the utility model are not limited to the technical means disclosed in the above-mentioned implementation mode, but also include technical solutions composed of any combination of the above technical features. It should be pointed out that for ordinary technicians in this technical field, several improvements and modifications can be made without departing from the principle of the utility model, and these improvements and modifications are also regarded as the protection scope of the utility model.
