Description

Technical Field

[0001] The utility model relates to the technical field of stove burners, in particular to a burner structure with convenient disassembly of an ignition needle. Background Art

[0002] The burner is the core component of the gas stove. The burner is mainly composed of a base, an ignition distributor, a fire cover, an ignition needle and a detection probe. Since the use environment of the ignition needle of the stove is generally accompanied by oil stains, due to long-term use, carbon deposits will form on the surface of the ignition needle and covered with oil stains, making the ignition needle unable to generate sparks. Therefore, the ignition needle needs to be cleaned of carbon deposits and oil stains on the surface regularly. If the surface of the ignition needle is directly wiped, the amount of cleaning liquid is difficult to control, and the cleaning liquid remains on the ignition needle, which will also damage the ignition needle; therefore, when the ignition needle is cleaned or replaced, the ignition needle needs to be removed; the existing ignition needle structure is generally a threaded connection structure. When the ignition needle is exposed to high temperature and oil stains for a long time, the position of the screw thread is prone to corrosion, resulting in slipping. Moreover, the position where the ignition needle is connected to the base is generally narrow, and a special sleeve needs to be inserted, which is inconvenient to disassemble. Utility Model Content

[0028] The utility model is further described below in conjunction with the accompanying drawings.

[0029] like Figures 1 to 8 As shown, the utility model discloses a burner structure with convenient detachable ignition needle, which comprises a base 1, an ignition distributor 5 fixed on the base 1 and a fire cover 4 arranged on the ignition distributor 5; the base 1 is provided with an ignition needle 3; after the gas enters from the base 1, it enters the cavity between the ignition distributor 5 and the fire cover 4 through the air inlet channel 501 and the air outlet groove 502 of the ignition distributor 5, and finally is discharged from the uniform air hole of the fire cover 4; the ignition distributor 5 and the fire cover 4 are essentially the same as those of the prior art, so they are not described in detail;

[0030] The base 1 is provided with a through hole 102 matching the ignition needle 3; the ignition needle 3 is slidably connected in the through hole 102; a spring bar 202 placed above the base 1 is fixed to the ignition needle 3; an insertion bar 202a is provided at the end of the spring bar 202; a positioning groove 101 is provided on the side surface of the base 1; the end of the insertion bar 202a is pressed into the positioning groove 101 through the spring bar 202;

[0031] The ignition needle 3 is slidably connected in the through hole 102, so the ignition needle 3 cannot rotate in the through hole 102;

[0032] The spring bar 202 blocks the upper surface of the base 1, so that the ignition needle 3 will not fall out of the through hole 102. In addition, the torsion of the spring bar 202 makes the insertion bar 202a stuck in the positioning groove 101, preventing the ignition needle 3 from moving up and down, so that the ignition needle 3 can be firmly connected to the base 1; when the ignition needle 3 needs to be removed, the resistance of the spring bar 202 is overcome and the spring bar 202 is moved, so that the insertion bar 202a is pulled out from the positioning groove 101, so that the entire ignition needle 3 can be pulled out from the through hole 102 from bottom to top; when installing the ignition needle 3, the ignition needle 3 is first inserted from top to bottom, and then the spring bar 202 is pulled to insert the insertion bar 202a into the positioning groove 101; when the ignition needle 3 of the burner structure is disassembled and assembled, only the spring bar 202 needs to be operated, and the ignition needle 3 is easy to disassemble and assemble.

[0033] As a preferred embodiment of the present invention, the spring strip 202 is a stainless steel spring sheet.

[0034] As a preferred embodiment of the utility model, a guide groove 102a is provided on the side wall of the through hole 102; a guide block 302 matching the guide groove 102a is provided on the outer side wall of the ignition needle 3; the guide block 302 is inserted into the guide groove 102a; the guide block 302 is connected with the guide groove 102a, so that the ignition needle 3 and the base 1 form a sliding connection to prevent the ignition needle 3 from rotating on the base 1.

[0035] As a preferred embodiment of the present invention, the ignition needle 3 is buckled with a U-shaped card 2; the end of the spring strip 202 away from the insertion strip 202a is fixedly connected to the U-shaped card 2;

[0036] The left and right sides of the U-shaped card 2 are provided with slots 203; the two sides of the ignition needle 3 are provided with convex strips 301 used in pair with the slots 203; after the U-shaped card 2 is inserted into the ignition needle 3, the two convex strips 301 are respectively inserted into the slots 203 on both sides;

[0037] The U-shaped card 2 is elastic, and the spring strip 202 is clamped on the ignition pin 3 through the U-shaped card 2, which facilitates the disassembly and assembly of the spring strip 202 and the ignition pin 3. The ignition pin 3 can be replaced separately, and the old U-shaped card 2 and spring strip 202 can still be used; the width of the convex strip 301 is equal to the width of the slot 203; the length of the convex strip 301 is equal to the length of the slot 203, so that the convex strip 301 can be clamped on the slot 203.

[0038] As a preferred embodiment of the present invention, a chamfered surface 301a is provided at one end of the convex strip 301; the chamfered surface 301a is used to guide the U-shaped card 2 when it is inserted into the ignition needle 3, and to open the U-shaped card 2 to an angle that allows it to pass through the convex strip 301; and no chamfered surface is required at the other end of the convex strip 301.

[0039] As a preferred embodiment of the present invention, guide plates 204 are provided at both ends of the U-shaped card 2; the distance between the two guide plates 204 gradually increases in the direction away from the U-shaped card 2; the U-shaped card 2 can automatically open its angle after the guide plates 204 press the surface of the ignition needle 3, so as to facilitate the assembly of the U-shaped card 2.

[0040] As a preferred embodiment of the present invention, a baffle 201 is provided on the outer surface of the U-shaped card 2; the baffle 201 is tightly attached to the surface of the base 1; the baffle 201 is used to support the U-shaped card 2, reduce the pressure of the spring bar 202 on the base 1, and prevent the spring bar 202 from being compressed and deformed in the vertical direction.

[0041] The above description is only a preferred embodiment of the present utility model, so all equivalent changes or modifications made according to the structure, features and principles described in the scope of the present utility model patent application are included in the scope of the present utility model patent application.
