New description: [New technical field] This creation is related to the burner of the gas furnace, especially for a gas burner with a combustion efficiency. 5 [Prior Art] The burner of a conventional gas furnace is provided with a hob above a furnace seat, and the hob is provided with a plurality of vertical upward fire holes for the flame to be ejected. However, when the flame is ejected vertically upwards, the heat at the bottom of the pan will not be averaged, resulting in the need to constantly move the pan to allow the pan to be heated on average, but it causes trouble and inconvenience in the cooking process. In addition, there is an external flame type gas burner, such as the gas stove head disclosed in the Republic of China Patent No. 200736548, which is attached to the furnace seat and has several inclined fire outlets. Radial outward ejection is exhibited via the firing ports. However, after the flame is ejected, it is easy to run to the outer edge of the pin and it is impossible to effectively concentrate the flame on the steel bottom, resulting in limited heating effect of the steel sole. Therefore, the external flame type burner has poor combustion efficiency, and the heating time required for food is also long, which will lead to waste of energy. [New content] The main purpose of this creation is to provide a concentrated flame to improve combustion efficiency. R kind of gas furnace furnace master's can achieve the above purpose, the creation of the -f and two furnace tubes. The furnace seat has an outer ring portion == containing a % portion within the outer portion of the outer ring portion, wherein the inner edge of the outer ring portion has a -th oblique γ, and each has a slanting surface. There is also a first fire exit hole, and the outer edge of the inner ring portion has a ^th-slope surface. The second second slope has a plurality of second fire holes; the two furnaces are separated from the furnace seat. Ring and inner ring. ▲By the first slanting surface of the outer ring portion of the outer ring and the second slanting surface of the inner ring portion, the slanting surface of the second slanting surface of the inner ring portion can be effectively set through the first fire hole and the second fire hole. The towel 'called the burning efficiency of the age. [Embodiment] In order to explain the structure, characteristics and effects of this creation, the following is a comparison of the following examples, and the description of the examples is as follows. Referring to the first to second figures, a gas burner head (10) according to a preferred embodiment of the present invention is made of a metal material (such as copper or cast iron body, and includes a furnace seat). (20) and two furnace tubes (3〇). The furnace seat (2〇) has an outer ring portion (40) and an inner ring portion (50). The inner edge of the outer ring portion (40) b has one outer a first inclined surface (42) inclined downwardly, the top edge, the middle and the bottom edge of the first inclined surface (42) are respectively provided with a plurality of first fire holes (44) (46) (48), wherein the top edge is The first fire hole (44) (46) of the bottom edge is opposite to each other, and the fire hole (48) between the two sides is formed between the adjacent two pairs of first fire holes (44) (46). The outer edge of (5〇) has a second inclined surface (52) which is inclined downward from the inside to the outside, and the top edge, the middle and the bottom edge of the second inclined surface (52) are respectively provided with a plurality of second fire holes ( 54) (56) (58), wherein the second fire hole (54) (56) at the top edge and the bottom edge are opposite each other, and the second fire hole (58) located in the middle is formed in the adjacent two pairs Between the two fire holes (54) and (56), the furnace seat (20) has an inner ring portion (50) and an outer ring portion (4 inch) respectively. 5 M345960 has a furnace chamber (60) ' as shown in the third figure. 凊 With the third diagram, the furnace tubes (3 〇) are horizontally connected to the outer W and the inner ring (5G), respectively, so that the gas can pass: The furnace (10) smoothly enters the outer soil portion (40) and the _ portion (10) furnace, and then passes through the ignition-external ring portion (40) of the first-out fire hole (44) (46) (48) and inside The ring outlet holes (54) (56) (58) are thrown out. - From the above structure, it is known that after the fire (45) (46) (48) of the outer ring portion (4) is thrown out, the heat of the first inclined surface (9) will be formed to form the internal heating. When the fire wrinkles through the inner ring portion (5〇): ^ hole (54) (56) (58 after that, due to the design of the second inclined surface (52), the outer flame is heated outward, so that The creation uses an external flame-type internal break-type combination design, so that the flame drawn through the _6) (48) of the outer ring portion (10) and the second 15 窜 through the inner ring portion (10) can effectively Concentrate on the bottom of the pot, so that the bottom of the pin can: thousands of average, increase combustion efficiency, the time required for food heating can be known: hunting to save energy. It must be said that the structure of the creation is not limited to the formation of the body, but the furnace seat (2G) can also be designed as a two-piece structure. In other words, the created furnace seat (2G) can be designed to have an upper cover (10) and a first fire outlet (54) (56) (58) as shown in the fourth figure. This creation is disclosed in #敬关巾(四)成Γ, and is not intended to limit the scope of this case. The other equivalent components should also be covered by the scope of the patent application. 〆 6 20 M345960 [Simplified description of the drawings] The first figure is a perspective view of a preferred embodiment of the present invention.
