Description

Technical Field

[0001] The utility model relates to the technical field of kitchen appliances, in particular to an ignition needle structure, a burner and a gas stove. Background Art

[0002] Generally, the ignition sensor needle of the infrared gas stove on the market is set in the middle of the burner.

[0029] The following examples illustrate the present invention, but the present invention is not limited by these examples. Modifications to the specific implementation of the present invention or equivalent replacement of some technical features without departing from the spirit of the present invention should be included in the scope of the technical solution claimed for protection in the present invention.

[0030] Please refer to Figure 1-Figure 4The utility model provides an ignition needle structure, including an ignition needle 1, a shielding cover 2 and a limiting member 3. The ignition needle 1 includes an ignition needle body 11 and a first limiting slot 10 arranged on the upper part of the ignition needle body 11, and the first limiting slot 10 is opened on the peripheral side of the ignition needle body 11 and opened in the horizontal direction. The shielding cover 2 includes a cover body 21 and a first limiting portion 22 arranged on the lower side of the cover body 21, and a limiting slot 220 with an opening facing downward is formed in the middle of the first limiting portion 22. A second limiting slot 23 corresponding to the first limiting slot 10 is opened on the peripheral side of the first limiting portion 22 in the horizontal direction. The upper part of the ignition needle body 11 is inserted into the limiting slot 220 to limit the horizontal position of the ignition needle body 11 and the shielding cover 2 (i.e., limit the XY direction). The stopper 3 is detachably connected to the cover body 21 and can slide relative to the cover body 21 between the first position and the second position. When the stopper 3 is in the first position, at least a portion of the stopper 3 is located in the first stopper slot 10 and the second stopper slot 23 to limit the position of the ignition needle body 11 and the shielding cover 2 in the vertical direction (i.e., to limit the Z direction). Thus, the shielding cover 2 and the ignition needle 1 are limited in the XYZ direction to ensure that the shielding cover 2 can be stably installed on the ignition needle 1. When the stopper 3 is in the second position, the stopper 3 is removed from the first stopper slot 10 and the second stopper slot 23, thereby realizing the disassembly between the ignition needle 1 and the shielding cover 2. The ignition needle structure provided by the utility model can better realize the installation and positioning between the ignition needle 1 and the shielding cover 2, and has a simple structure and is easy to disassemble and assemble, which effectively improves the installation stability between the shielding cover 2 and the ignition needle 1, and solves the problem in the prior art that the ignition needle 1 discharges to the shielding cover 2 when the shielding cover 2 is installed on the burner assembly, thereby causing the ignition to fail to ignite normally.

[0031] Optionally, the limiting member 3 includes a limiting plate 31 and a second limiting portion 32 arranged at one end of the limiting plate 31. When the limiting member 3 is in the first position, the second limiting portion 32 extends into the first limiting slot 10 and the second limiting slot 23. When the limiting member 3 is in the second position, the second limiting portion 32 moves out from the first limiting slot 10 and the second limiting slot 23.

[0032] Optionally, a limiting block 24 is further provided on the lower side of the cover body 21, and a third limiting slot 240 is formed between the limiting block 24 and the lower side of the cover body 21. When the limiting member 3 is in the first position, at least a portion of the limiting plate 31 is located in the third limiting slot 240. By providing the limiting block 24 to support the limiting plate 31, the limiting plate 31 can be stably installed on the cover body 21.

[0033] Optionally, two limit blocks 24 are provided, and the two limit blocks 24 are spaced apart, and when the limit member 3 is in the first position, two opposite sides of the limit plate 31 are both located in the third limit slot 240. By providing two limit blocks 24, the limit plate 31 can be more stably installed on the cover body 21.

[0034] Specifically, when producing the ignition needle structure, the limiting member 3 is first inserted along the limiting slot to the first position, at which time the limiting portion 32 is inserted into the second limiting slot 23, and the limiting member 3 is installed as a whole on the shielding cover 2, so that the limiting member 3 and the shielding cover 2 form a whole, which is convenient for transportation and storage. When the shielding cover 2 is assembled with the ignition needle 1, the limiting member 3 is first moved from the first position to the second position, and then the upper part of the ignition needle body 11 is inserted into the limiting slot 220, and then the limiting member 3 is slid along the limiting slot to the first position, that is, to the position where the limiting portion 32 is inserted into the first limiting slot 10 and the second limiting slot 23, so that the installation between the ignition needle 1 and the shielding cover 2 is completed.

[0035] Optionally, a handle portion 33 is further provided at one end of the limiting plate 31 away from the second limiting portion 32, and the handle portion 33 is extended downwardly. The handle portion 33 is provided to facilitate pushing the limiting plate 31 to slide between the first position and the second position.

[0036] Optionally, two second limiting portions 32, two first limiting slots 10, and two second limiting slots 23 are provided, one end of the limiting plate 31 is provided with an avoidance slot 30, and two opposite ends of the avoidance slot 30 form two oppositely arranged second limiting portions 32, one opposite side of the ignition needle body 11 is provided with a first limiting slot 10, and one opposite side of the first limiting portion 22 is provided with a second limiting slot 23. By providing two second limiting portions 32, the first limiting slot 10, and the second limiting slot 23, the installation stability between the shielding cover 2 and the ignition needle 1 is improved.

[0037] Optionally, a connecting portion 12 is provided on the upper portion of the ignition needle body 11, and the connecting portion 12 is inserted into the limiting slot 220. The shape of the cross section of the connecting portion 12 is the same as the shape of the cross section of the limiting slot 220 and is non-circular, thereby realizing horizontal limitation between the ignition needle body 11 and the cover body 21.

[0038] Another aspect of the utility model provides a burner, comprising the above-mentioned ignition needle structure.

[0039] In another aspect, the utility model provides a gas stove, comprising the burner mentioned above.

[0040] The above are only some embodiments of the present invention. For those skilled in the art, several modifications and improvements can be made without departing from the inventive concept of the present invention, which all belong to the protection scope of the present invention.
