[0036] Refer to the following Figure 1 and Figure 2 The present invention describes an ignition needle mounting structure, a burner, and a stove according to some embodiments of the present application.

[0037] This application provides an ignition needle installation structure, such as Figure 1 and Figure 2 As shown, the ignition needle mounting structure includes a burner head 1, an ignition needle 2 and a spring retaining ring 3. A through hole 12 is provided on the burner head 1, and a first groove 13 is provided on the inner wall of the through hole 12, and the first groove 13 is annular along the circumference of the through hole 12; a second groove 21 is provided on the outer wall of the ignition needle 2, and the second groove 21 is annular along the circumference of the ignition needle 2. The ignition needle 2 can be inserted into the through hole 12, and the second groove 21 is opposite to the first groove 13; the spring retaining ring 3 is sleeved on the ignition needle 2, and the radial inner side of the spring retaining ring 3 is located in the second groove 21, and the radial outer side of the spring retaining ring 3 is located in the first groove 13, so that the ignition needle 2 is axially limited on the burner head 1 by the spring retaining ring 3.

[0038] The spring ring 3 is elastic. When the spring ring 3 is squeezed inward, the spring ring 3 can be elastically deformed to shrink toward the inside of the second groove 21; therefore, when the ignition needle 2 is inserted or removed, the spring ring 3 can shrink under the squeezing of the inner wall of the through hole 12, so that it can smoothly enter and exit the through hole 12 with the ignition needle 2. When the ignition needle 2 moves to the second groove 21 and is opposite to the first groove 13, the spring ring 3 can expand to restore the deformation, so that the radial outer side of the spring ring 3 extends into the first groove 13 to axially limit the ignition needle 2, thereby realizing the installation of the ignition needle 2 on the burner head 1 through the spring ring 3, and making the disassembly and assembly of the ignition needle 2 more convenient, and the disassembly and assembly process will not damage the ignition needle 2.

[0039] In one embodiment of the present application, preferably, Figure 1 and Figure 2 As shown, the spring retaining ring 3 is C-shaped with an opening, and the inner diameter of the spring retaining ring 3 is larger than the diameter of the circumference of the bottom wall of the second groove 21, so that when the spring retaining ring 3 is installed in the second groove 21, the spring retaining ring 3 does not hold the bottom wall of the second groove 21 tightly, thereby reserving space for the spring retaining ring 3 to be squeezed and deformed, and when the spring retaining ring 3 is squeezed, it will not squeeze the ignition needle 2, thereby avoiding damage to the ignition needle 2.

[0040] In one embodiment of the present application, preferably, Figure 2 As shown, a chamfered surface 14 is provided at the end of the through hole 12, so that the end of the through hole 12 is expanded; when the ignition needle 2 and the spring retaining ring 3 on the ignition needle 2 are inserted into the through hole 12, the radial outer side of the spring retaining ring 3 can first contact the chamfered surface 14, so that as the ignition needle 2 continues to be inserted into the through hole 12, the chamfered surface 14 can squeeze the spring retaining ring 3, so that the spring retaining ring 3 shrinks and smoothly enters the through hole 12.

[0041] In one embodiment of the present application, the first groove 13 on the inner wall of the through hole 12 is arc-shaped, so that when the ignition needle 2 is pulled out from the through hole 12, the spring ring 3 can be squeezed into the second groove 21 by the inner wall of the first groove 13, thereby allowing the spring ring 3 to smoothly withdraw from the first groove 13, thereby improving the convenience of disassembly and assembly of the ignition needle 2.

[0042] In another embodiment of the present application, Figure 2 As shown, the first groove 13 is trapezoidal and includes a bottom wall and two opposite side walls. The two side walls are obliquely connected to the bottom wall, and the angles between the two side walls and the bottom wall are both obtuse angles. Therefore, when the ignition needle 2 is pulled out of the through hole 12, the spring ring 3 contracts inwardly under the pressure of the inclined side walls to smoothly withdraw from the first groove 13.

[0043] In one embodiment of the present application, preferably, a plurality of second grooves 21 are provided on the outer wall of the ignition needle 2, and the plurality of second grooves 21 are arranged at intervals along the length direction of the ignition needle 2. The spring retaining ring 3 can be installed in any second groove 21, and the second groove 21 on which the spring retaining ring 3 is installed is made opposite to the first groove 13 on the inner wall of the through hole 12, so that the installation height of the ignition needle 2 on the burner head 1 can be adjusted to adapt to a variety of fire covers of different heights on the burner head 1 to ensure an effective ignition distance.

[0044] In another embodiment of the present application, preferably, Figure 2 As shown, a plurality of first grooves 13 are provided on the inner wall of the through hole 12, and the plurality of first grooves 13 are spaced apart along the axial direction of the through hole 12. When installing the ignition needle 2, the second groove 21 of the ignition needle 2 can be made opposite to the first groove 13 at any height, thereby realizing adjustment of the installation height of the ignition needle 2 to adapt to a variety of fire covers of different heights on the burner 1 and ensure an effective ignition distance.

[0045] In one embodiment of the present application, preferably, Figure 1 and Figure 2 As shown, when the burner 1 is placed horizontally, the axis of the through hole 12 extends in the vertical direction, the upper end of the through hole 12 passes through the top of the burner 1, and the lower end of the through hole 12 passes through the bottom of the burner 1, and a boss 11 is provided at the bottom of the burner 1, and the through hole 12 is opened on the boss 11, thereby increasing the height of the through hole 12 to a certain extent, ensuring that the ignition needle 2 can be vertically inserted into the through hole 12, avoiding the ignition needle 2 from being deflected, and also enabling a plurality of first grooves 13 to be provided on the inner wall of the through hole 12 along the axial direction of the through hole 12.

[0046] The present application also provides a burner and a stove including the burner.

[0047] In this embodiment, the burner includes an ignition needle mounting structure, so the burner and the stove including the burner also have all the beneficial effects of the ignition needle mounting structure, which will not be described in detail here.
