[0002] At present, the burner head of commercial stoves is a commonly used stove. For example, Chinese patent document CN118361762A discloses a stainless steel environmentally friendly burner head base, including a base, a fire starter, a fire detector pin, and an ignition pin. A circular slot is provided in the middle of the base, and a mounting block is provided on one side of the base. An ignition pin hole position one, a fire detector pin hole position one, and a fire starter hole position one are respectively provided inside the mounting block. The bottom of the mounting block is connected to the fixing code by screws, and a fire detector pin hole position two, an ignition pin hole position two, and a fire starter hole position two are provided on the fixing code. The ignition pin shell is inserted into the ignition pin hole position one, an ignition pin is provided above the ignition pin shell, a screw fixing position two is provided at the bottom of the ignition pin shell, and the fire detector shell is inserted into the fire detector pin hole position one.

[0003] In the above structure, it can be seen from the drawings in the specification that in the prior art, the upper surfaces of the ignition pin hole position 1, the fire detection pin hole position 1 and the fire through hole position 1 on the mounting block on one side of the base are all flush and flush with the mounting block, so that the fire is retained on the surface. However, in actual cooking, chefs basically "toss the pot" to cook, so that the pot is constantly lifted and put down on the base, which causes the air pressure and airflow in the stove head to constantly change, so that when the airflow and air pressure pass through the fire on the surface, the fire is unstable and even easily extinguished. After the fire is extinguished, the flameout controller is turned off, so that the ignition operation needs to be re-ignited, which is inconvenient to use. Utility Model Content

[0004] In order to overcome the defects of the prior art, the utility model provides an anti-flameout burner head, aiming to solve the above problems.

[0005] The technical solution adopted by the utility model to solve its technical problems is: an anti-flameout stove head, including a stove shell, a combustion chamber is arranged in the stove shell, an ignition platform is arranged on the side of the stove shell, a strip groove is opened on the ignition platform, an ignition sensing needle assembly and an air outlet end are respectively installed in the strip groove, an air outlet hole is arranged on the side of the air outlet end so that the air outlet hole is located in the strip groove, a cover body is arranged on the ignition platform, an ignition chamber is formed between the cover body and the ignition platform, and an opening corresponding to the combustion chamber is arranged on one side of the ignition chamber.

[0006] In the above-mentioned anti-flameout stove head, a fire starter tube hole, an ignition needle tube hole and a sensing needle tube hole are respectively opened in the strip groove, a fire starter tube is installed in the fire starter tube hole, the gas outlet end is located on one end of the fire starter tube, the ignition sensing needle assembly includes an ignition needle tube and a sensing needle tube, the ignition needle tube is installed in the ignition needle tube hole, the sensing needle tube is installed in the sensing needle tube hole, an ignition needle is arranged on the end face of one end of the ignition needle tube close to the strip groove, and a sensing needle is arranged on the end face of one end of the sensing needle tube close to the strip groove, and the ignition needle and the sensing needle extend to the top of the fire starter tube hole.

[0007] In the above-mentioned flameout-proof stove head, an air inlet end is arranged at one end of the spark tube away from the air outlet end, and a gas end is arranged at one side of the air inlet end.

[0008] In the above-mentioned flameout-proof burner head, the inner diameter of the fire tube hole is larger than the outer diameter of the gas outlet end, and the gas outlet hole is located inside the fire tube hole so that the gas outlet hole corresponds to the inner wall of the fire tube hole.

[0009] In the above flameout prevention stove head, positioning feet are arranged on both sides of the cover body, and positioning grooves corresponding to the positioning feet are arranged on both sides of the ignition platform.

[0010] The beneficial effect of the utility model is that by arranging the strip groove on the ignition table, and the air outlet hole at the air outlet end is located in the strip groove, so that the position of the air outlet hole is lower than the surface of the ignition table, when the pot is continuously lifted and lowered on the furnace shell during actual cooking, the airflow in the combustion chamber continuously changes and flows, so that the air pressure and airflow are pressed into the ignition chamber. Since the position of the air outlet hole is lower than the surface of the ignition table, the fire can be retained in the strip groove under the condition of changing airflow and air pressure, so as to prevent the fire from being extinguished by being pressed, and the use is more convenient.
