Description

Technical Field

[0001] The utility model relates to the technical field of burners for fuel appliances, in particular to a burner structure for quickly disassembling and assembling an ignition needle. Background Art

[0002] The burner is the core component of the gas stove. The burner is mainly composed of a base, a ignition distributor, a fire cover, an ignition needle and a detection probe. Since the ignition needle of the stove is usually used in an environment with oil stains, due to long-term use, carbon deposits and oil stains will form on the surface of the ignition needle, making it impossible for the ignition needle to generate sparks.

[0003] Therefore, the ignition needle needs to be regularly maintained and cleaned. However, since the top height of the ignition needle is generally set to be consistent with the height of the fire outlet of the fire cover, and the distance between the ignition needle and the fire cover is relatively close, the gap between the ignition needle and the fire cover is very narrow, making it difficult to insert a cleaning tool for cleaning. However, the existing ignition needle structure is generally connected to the ignition distributor through a nut thread. Oil stains can easily corrode the surface of the nut, making it easy to slip when tightening the nut, making it difficult to remove. When the corrosion is severe, the thread is prone to slippage, making the nut scrapped.

[0004] Therefore, it is necessary to further innovate the existing burner ignition pin connection structure. Utility Model Content

After being dispersed in the gas distribution chamber 504, the gas enters the interior of the fire cover 4 and finally is discharged from the gas holes of the fire cover 4 for combustion.

[0031] The side wall of the base 1 is provided with a connecting portion 101; a positioning hole 101a is provided on the connecting portion 101; a U-shaped card plate 3 is connected between the base 1 and the ignition needle 2; an upper positioning concave ring 201 and a lower positioning concave ring 202 are provided on the outer wall of the ignition needle 2; the U-shaped card plate 3 is composed of an upper card plate 301, a connecting plate 302 and a lower card plate 303; the upper card plate 301 is fixed to the lower card plate 303 through the connecting plate 302; the front end surface of the upper card plate 301 is provided with an upper U-shaped groove 301b; the front end surface of the lower card plate 303 is provided with a lower positioning groove 303b; the ignition needle 2 passes through the positioning hole 101a; the U-shaped card plate 3 is fixed on the connecting portion 101; the two sides of the U-shaped groove 301b are inserted into the upper positioning concave ring 201; the two sides of the lower positioning groove 303b are snapped into the lower positioning concave ring 202;

[0032] After the upper clamping plate 301 and the lower clamping plate 303 of the U-shaped clamping plate 3 are pressed against the upper and lower surfaces of the connecting portion 101 respectively, the U-shaped clamping plate 3 is clamped and fixed on the connecting portion 101;

[0033] The diameter of the ignition needle 2 is larger than the width of the upper U-shaped groove 301b, so that after the upper U-shaped groove 301b is inserted into the upper positioning concave ring 201, the top surface of the upper clamping plate 301 is pressed against the inner top wall of the upper positioning concave ring 201;

[0034] The diameter of the lower positioning groove 303b is also smaller than the diameter of the ignition needle 2; after the lower positioning groove 303b is inserted into the lower positioning recessed ring 202, the lower surface of the lower clamping plate 303 is pressed against the inner bottom wall of the lower positioning recessed ring 202; the ignition needle 2 is clamped and positioned by the upper clamping plate 301 and the lower clamping plate 303, so that the ignition needle 2 is fixed on the connecting part 101; when the ignition needle 2 needs to be removed, the U-shaped clamping plate 3 is pulled out horizontally, so that the upper clamping plate 301 and the lower clamping plate 303 are respectively separated from the upper positioning recessed ring 201 and the lower positioning recessed ring 202, and the ignition needle 2 can be pulled upward by one end to be misaligned with the fire cover 4.
