[0033] Next, refer to Figures 1 to 6 Describe the ignition pin installation structure, burner and cooking appliance according to some embodiments of the present application.

[0034] The present application provides an ignition pin installation structure, as Figures 1 to 3 shown. The ignition pin installation structure includes a burner head 1, an ignition pin 2 and an elastic member 3. An installation hole 12 is formed in the burner head 1. The burner head 1 is horizontally placed in the use state. The side of the burner head 1 facing upward is the top side of the burner head 1, and the side of the burner head 1 facing downward is the bottom side of the burner head 1. The axial direction of the installation hole 12 is along the vertical direction, and the installation hole 12 penetrates through the top side and the bottom side of the burner head 1. The ignition pin 2 is movably inserted into the installation hole 12. For example, the ignition pin 2 has a clearance fit with the installation hole 12, so that the ignition pin 2 can be lifted and lowered and rotated in the installation hole 12; as Figure 5As shown, a convex block 21 is provided on the side wall of the ignition pin 2, and a support surface is provided on the side of the top side of the burner head 1 in the radial direction of the mounting hole 12. The ignition pin 2 can be rotated until the convex block 21 faces the support surface, so that the convex block 21 is carried on the support surface to provide support for the convex block 21 and the ignition pin 2 through the support surface. An elastic member 3 is provided below the burner head 1. One end of the elastic member 3 abuts against the lower side of the burner head 1, and the other end of the elastic member 3 abuts against the ignition pin 2. Moreover, the elastic member 3 can provide a downward elastic force for the ignition pin 2, so that the convex block 21 of the ignition pin 2 and the support surface on the top side of the burner head 1 remain in a state of mutual abutment, thereby realizing the stable installation of the ignition pin 2 on the burner head 1. And compared with the traditional installation method that requires a retaining ring to be clamped on the ignition pin 2 for positioning, it can avoid damage to the ignition pin 2 during installation to a certain extent.

[0035] In an embodiment of the present application, preferably, as Figures 3 to 5 shown, an avoidance groove 13 is formed on the side wall of the mounting hole 12. The length direction of the avoidance groove 13 is along the vertical direction. The avoidance groove 13 is a through groove. One end in the length direction of the avoidance groove 13 penetrates the top surface of the burner head 1, and the other end in the length direction of the avoidance groove 13 penetrates the bottom surface of the burner head 1; the avoidance groove 13 is adapted to the convex block 21. The ignition pin 2 can be rotated until the convex block 21 faces the avoidance groove 13, so that when the ignition pin 2 is inserted into the mounting hole 12 from below the burner head 1, the convex block 21 can move from below the burner head 1 to above the burner head 1 through the avoidance groove 13, or when the ignition pin 2 is pulled out of the mounting hole 12 from below the burner head 1, the convex block 21 can move from above the burner head 1 to below the burner head 1 through the avoidance groove 13.

[0036] In an embodiment of the present application, preferably, the top surface of the burner head 1 is a support surface for supporting the convex block 21. When the ignition pin 2 is inserted into the mounting hole 12 from below the burner head 1 and the convex block 21 moves from below the burner head 1 to above the burner head 1 through the avoidance groove 13, rotate the ignition pin 2, and the convex block 21 can move away from the position opposite to the avoidance groove 13, so that the convex block 21 faces the top surface of the burner head 1 outside the mounting hole 12 and is supported on the top surface of the burner head 1.

[0037] In another embodiment of the present application, preferably, as Figure 5As shown, a stepped portion 14 is provided on the side wall of the mounting hole 12. The stepped portion 14 and the avoidance groove 13 are arranged at intervals along the circumferential direction of the mounting hole 12. The stepped portion 14 forms a stepped surface facing upward, and the stepped surface is the above-mentioned support surface. When the ignition needle 2 is inserted upward into the mounting hole 12 from below the burner head 1, and the convex block 21 moves from below the burner head 1 to above the burner head 1 through the avoidance groove 13, by rotating the ignition needle 2, the convex block 21 can move away from the position opposite to the avoidance groove 13 and move to a position opposite to the stepped portion. Then, the convex block 21 can enter the stepped portion 14 and be supported on the stepped surface, thereby realizing the support for the boss 11 and the ignition needle 2, and also restricting the rotation of the boss 11 and the ignition needle 2 through the stepped portion 14.

[0038] In this embodiment, preferably, as Figure 6 shown, a plurality of stepped portions 14 are provided on the side wall of the mounting hole 12. The avoidance groove 13 and the plurality of stepped portions 14 are arranged at intervals along the circumferential direction of the mounting hole 12. When the convex block 21 is located above the burner head 1, by rotating the ignition needle 2 at different angles, the ignition needle 2 can enter any stepped portion 14 and be supported on the stepped surface of the stepped portion 14. Moreover, the plurality of stepped portions 14 have different depths along the axial direction of the mounting hole 12, that is, the stepped surfaces of the plurality of stepped portions 14 have different heights in the vertical direction. Thus, by supporting the boss 11 on the stepped surfaces of different stepped portions 14, the ignition needle 2 can have different mounting heights to be adapted to the burner caps at multiple different heights of the cooking appliance and maintain an effective ignition distance.

[0039] In an embodiment of the present application, preferably, as Figures 1 to 3 shown, a boss 11 is formed on the bottom surface of the burner head 1, and the mounting hole 12 is provided on the boss 11. By providing the boss 11, the height of the mounting hole 12 can be extended to a certain extent, so as to facilitate the formation of a plurality of stepped portions 14 with different depths on the side wall of the mounting hole 12.

[0040] In an embodiment of the present application, preferably, as Figures 1 to 4 shown, the end of the ignition needle 2 located below the burner head 1 is the lower end of the ignition needle 2. An annular abutting portion 22 is formed around the circumferential direction of the ignition needle 2 at the lower end of the ignition needle 2. The elastic member 3 is sleeved on the ignition needle 2. The upper end of the elastic member 3 abuts against the bottom surface of the burner head 1, specifically the lower surface of the boss 11, and the lower end of the elastic member 3 abuts against the abutting portion 22 of the ignition needle 2; thereby, the elastic member 3 is stably installed between the ignition needle 2 and the burner head 1 to provide a downward elastic force for the ignition needle 2 through the elastic member 3, so that the boss 11 on the ignition needle 2 abuts tightly downward against the support surface.

[0041] Preferably, the elastic member 3 is conical, as Figure 3As shown, the elastic member 3 is gradually expanding from bottom to top, enabling both ends of the elastic member 3 to respectively abut against the opposite bosses 11 and the abutting portions 22, so as to provide a stable elastic force for the ignition needle 2.

[0042] During the actual disassembly and assembly process, when the ignition needle 2 needs to be installed on the burner head 1, first sleeve the elastic member 3 on the ignition needle 2, and then insert the ignition needle 2 into the mounting hole 12 from below the burner head 1. During the insertion process, make the protrusion 21 on the ignition needle 2 opposite to the avoidance groove 13, so that during the upward insertion of the ignition needle 2, the protrusion 21 moves above the burner head 1 through the avoidance groove 13, and then rotate the ignition needle 2 to make the protrusion 21 move into a stepped portion 14 and tightly abut against the stepped surface of the stepped portion 14 under the action of the elastic member 3. When the ignition needle 2 needs to be removed from the burner head 1, just compress the elastic member 3 to move the ignition needle 2 upward, so that the protrusion 21 moves out of the stepped portion 14, and then rotate the ignition needle 2 to make the protrusion 21 move opposite to the avoidance groove 13, and then the ignition needle 2 can be pulled out from below the burner head 1.

[0043] In summary, through the installation structure of the ignition needle 2 of the present application, the disassembly and assembly of the ignition needle 2 can be completed conveniently and quickly, and the disassembly and assembly process can avoid damaging the ignition needle 2.

[0044] The present application also provides a burner and a cooking appliance including the burner.

[0045] In this embodiment, the burner includes an ignition needle installation structure. Therefore, the burner and the cooking appliance including the burner also have all the beneficial effects of the ignition needle installation structure, which will not be elaborated here one by one.
