Description of the new type: [Technical field to which the new type belongs] This creation relates to a gas burner, especially one that is beneficial to the use of-temperature control switch, will not cause direct heating of the temperature control switch and cause the second _ action "Gas stove". ^ [Prior art] Please refer to the fourth to sixth figures. Generally, the gas stove is attached to the base (10) with a ring-shaped container (101). The container (101) is connected to a duct (1〇) at the end. 2) The top surface of the annular container (101) of the base (10) is covered with a top cover φ (20) by inflowing gas, and the top cover (2) is connected to the middle of the ring cover (3) to set a top seat ( 4〇), the ring cover (30) is provided with a plurality of grooves (301) on the outer periphery, and the top seat (40) is provided with an oblique ring surface (401) and an oblique ring at the parent joint with the ring cover (30). The surface (401) is provided with a plurality of through holes (402), and further, a convex ring (403) is provided in the middle of the top seat (40), and a plurality of convection holes (404) are provided on the side wall of the convex ring (403). When assembling, in order to avoid accidents caused by air burning, a temperature control switch (50) is usually installed at the center of the base (10) and the convex ring (403) of the top (40) of the stove head for connection with the stove head. Place the bottom of the cooking container against the touch. When in use, _ open the gas, the gas will flow from the duct (102) into the chamber (101), and then flow out of the groove (301) and through hole (402) to match the ignition and combustion, you can cook the vessel Heat to cook. Since the temperature control switch (50) is in contact with the bottom of the cooking container during cooking, the temperature control switch (50) is continuously heated when the cooking container is heated, resulting in air-burning. It will cooperate with the control circuit to immediately turn off the gas switch automatically or trigger the alarm sound, etc., so as to avoid accidents. 5 M263470 However, in actual use, because the inclined ring surface (401) and through hole (402) of the top seat (40) will just face the temperature control switch (50), and the convex ring (403) is provided with many convection holes ( 404), so that the gas emitted from the through hole (402) is ignited, and the flame will flow with the airflow through the convection hole (404) and heat toward the temperature control switch (50). So, if over a period of time, Then, the temperature control switch (50) will mistakenly sense that the temperature reaches a wrong value, and the malfunction, that is, suddenly turning off the gas switch or triggering the alarm sounds, will cause great trouble to the user. [New content] In order to solve the above-mentioned lack of knowledge, the creator is a diligent _ God, and carefully developed this creation. This creation relates to a gas burner head, which is provided with a circular chamber on the base. One end of the chamber communicates with a duct for gas to flow in. The circular chamber of the base covers the top surface to cover a top cover. The middle part of the ring cover is provided with a top seat, and the outer periphery of the ring cover is provided with a plurality of grooves. Its characteristics are: the ring cover is provided with a plurality of through holes communicating with the bottom side on the top side, and a middle part is provided with a There are no convex rings with through holes on the side wall, and there are many convection holes between the outer edge of the top seat and the convex rings. [Embodiment] 0 First, please refer to Figure ^ 3, the gas stove of this creation is attached to the base (1) with a ring-shaped container (11), and one end of the container (1 丨) communicates with a guide. Officer (12) for gas inflow, the top surface of the annular container (11) of the base (1) is closed — = cover (2); the top cover (2) is attached to the middle of the ring cover (21) and a top seat ( 22), the outer periphery of the J-cover (21) is provided with a plurality of grooves (211), and the ring cover (21) is provided on the top side with a plurality of through holes (212) communicating with the bottom side, and further, the top seat (22) A convex ring (221) without a through hole in the sidewall is provided in the middle, and a plurality of convection holes (222) are provided between the outer edge of the top seat (22) and the convex ring (221). 6 M263470 During assembly, in order to avoid accidents due to air-burning, it is often set (3) in the center of 摅 通 I ⑴ and the convex ring 顶 of the top seat ， for contact with the bottom of the cooking container placed on the stove. . When in use, open the gas, the gas will flow from the duct (12) into the chamber (11), and then flow out of the groove (211) and the through hole (212) 'to match the ignition and combustion', you can heat the hen cooking capacity test, To cook. Since the 'temperature control switch (3) is in contact with the bottom of the cooking container during cooking, when the cooking container is continuously heated, resulting in empty cooking, the temperature reaches the-preset value, the temperature control switch (3 ) Will cooperate with the control circuit to automatically turn off the gas switch or trigger the alarm sound, etc., to avoid accidents. From the above structure, it can be known that the gas stove head of this creation is to set the groove (211) and through hole (212) for gas outflow at a position farther from the temperature control switch (3), and set the temperature control switch (3) in a ring. The side wall of the convex ring (221) is closed without a through hole. At the same time, the convection hole (222) is provided outside the convex ring (221). Therefore, it is ejected from the groove (221) and the through hole (212). After the gas is ignited, the flame will not heat toward the temperature control switch (3), so the temperature control switch (3) will not malfunction and suddenly turn off the gas switch or trigger the alarm. In summary, this creative embodiment can indeed achieve the expected use effect, and the specific structure disclosed is not only not found in similar products, nor disclosed before the application, and has fully met the requirements and requirements of the Patent Law. If you apply for a new type of patent in accordance with the law, you are kindly requested to review it and grant the patent. 7 M263470 [Brief description of the drawings] The first picture: a three-dimensional exploded view of the creation.
