Description

Technical Field

[0001] The utility model relates to the technical field of gas stoves, in particular to a burner. Background Art

[0002] In existing stoves, the ignition distributor, induction needle and ignition needle are usually installed directly on the burner. When a fault occurs and needs to be replaced, it is usually necessary to remove the entire ignition distributor from the stove and reinstall the ignition needle, induction needle and ignition distributor. However, the insulating parts of the ignition needle and the induction needle are made of ceramic material. The dimensional tolerance of the ceramic body after molding is large, resulting in the need to reserve a large gap during assembly to complete the assembly. In the case of a large matching gap, flexible fixation with elastic deformation is used, resulting in the ignition needle and the induction needle being easy to shake. After shaking, the ignition needle will be close to the fire cover or away from the fire cover. When the ignition needle is close to the fire cover, the discharge end of the ignition needle is close to the fire cover, resulting in a shorter discharge distance, a corresponding shorter arc length, and a lower ignition success rate. When the ignition needle is away from the fire cover, the discharge end of the ignition needle is away from the fire cover, the discharge distance becomes longer, and the arc formation success rate is reduced, thereby reducing the ignition success rate.

[0043] In a preferred embodiment of the present invention, Figure 1-2 The burner shown also includes a limiting member 5 for limiting the position of the ignition divider 4, and the other end of the limiting member 5 is detachably connected to the ignition divider 4. The burner head 1 and the ignition divider 4 are connected in a split combination, and the ignition divider 4 can be limited and the burner head 1 and the ignition divider 4 can be connected simply by connecting the ignition divider 4 to the limiting member 5.

[0044] In a preferred embodiment of the present invention, Figure 1-7 The illustrated limiting member 5 includes a limiting block 51, and the igniter 4 is provided with a second limiting groove 42 corresponding to the limiting block 51. The limiting block 51 is connected to the side of the pressing block 31 away from the needle body 21, and the top of the limiting block 51 is inserted into the second limiting groove 42. The limiting block 51 and the fixing structure 3 are integrally formed. During installation, it is only necessary to align and connect the second limiting groove 42 and the limiting block 51, so that the igniter 4 and the needle body 21 can be aligned and limited, so that the distance between the needle body 21 and the igniter 4 is within a preset range, thereby improving the ignition effect.

[0045] In a preferred embodiment of the present invention, Figure 1-7 The inner wall of the through hole 41 shown is recessed outward to form a second limiting groove 42, and the inner wall of the through hole 41 is connected to a limiting column 6 on a side away from the second limiting groove 42, and the limiting column 6 abuts against the outer wall of the needle body 21. In this way, the through hole 41 and the second limiting groove 42 are connected, and the needle body 21 and the limiting block 51 on the pressing block 31 are inserted as a whole into the through hole 411 and the second limiting groove 42, which can further limit the X direction of the needle body 21 to prevent the needle body 21 from shaking; the ignition distributor 4 can also be limited, simplifying the installation process, while improving the installation stability of the needle body 21, and ensuring the ignition effect.

[0046] Specific installation process:

[0047] First, connect the needle body 21 to the mounting block 11, then insert the pressing block 31 into the low limit groove 210, and at the same time, bolt the fixing block 32 to the burner head 1 to fix the needle body 21, solve the problem of the shaking of the ignition needle, improve the reliability of the fixation of the needle body 21, and at the same time ensure that the ignition success rate does not decrease, better protect the ceramic body of the needle body 21, and reduce the risk of the ceramic body of the needle body 21 breaking. Since the point limit block 51 and the fixed structure 3 are integrally formed, at this time, the positions of the needle body 21, the fixed structure 3 and the limit block 51 are relatively unchanged. It is only necessary to align and connect the second limit groove 42 and the limit block 51 to achieve the alignment and limit of the ignition divider 4 and the ignition needle 21, so that the distance between the ignition needle 21 and the ignition divider 4 is within the preset range, thereby improving the ignition effect. By adopting a stacking installation method from bottom to top, the needle body 21 does not need to be turned over to install the burner head, which can effectively reduce unnecessary installation actions, improve assembly efficiency, and facilitate after-sales maintenance.
