[0001] The utility model relates to the technical field of gas cookers, in particular to a base and a burner head. Background Art

[0002] Integrated cooktops and gas cookers are commonly used kitchen utensils in families, and the burner head is an important part of integrated cooktops and gas cookers. Some components of the burner head, especially the burner cap, are usually cast with copper, resulting in a high cost.

[0003] According to the prior art, there is an external burner head and a burner head with the external burner head, with the publication number CN116892725A, which includes an external burner head base, an external baffle, an external fire plate and an external connecting sleeve. The external burner head base, the external baffle, the external connecting sleeve, the external air inlet sleeve and the external fire plate are all made of stainless steel. Using stainless steel instead of copper, however, stainless steel undergoes annealing during long-term use, causing rust and a short service life. In addition, stainless steel is difficult to process, resulting in a high cost. Summary of the Utility Model

[0004] The technical problem to be solved by the utility model is to overcome the above defects of the prior art and provide a base and a burner head with a long service life and low processing difficulty.

[0009] After adopting the above structure, the utility model has the following advantages compared with the prior art: the base is divided into a positioning ring, a lower base and an upper base. The outer ring burner cap is installed on the positioning ring, and the fire holes on the outer ring burner cap are close to the positioning ring. The positioning ring is subjected to a relatively high temperature of the flame burning. The positioning ring is made of copper, which is more heat-resistant and will not produce annealing phenomenon, so it has a long service life; at the same time, since the temperature of the lower base and the upper base subjected to the flame burning is relatively low, at least one of the upper base and the lower base is selected as a high-temperature resistant product, such as aluminum, which has low processing difficulty and greatly reduces the cost.

[0010] Preferably, when the upper base and the lower base are of the same material, the upper base and the lower base are of an integral structure, which is convenient for mass production and has a low cost.

[0011] Preferably, when the upper base and the lower base are made of different materials, the upper base and the lower base are of a split structure, which is convenient to be fixed together.

[0012] Preferably, the upper base and the lower base are detachably connected, which is convenient for installation and disassembly.

[0013] Preferably, the upper base and the lower base are connected together by bolts, and the structure is simple.

[0014] Preferably, a plurality of downward-opening slots are provided on the bottom surface of the upper base; when the upper base and the lower base are connected together, the slots and the upper surface of the upper base form a gas supply channel, which is formed by combining the upper base and the lower base, and there is no need for additional processing of the gas supply channel, with low processing difficulty and low cost.

DETAILED DESCRIPTION OF THE INVENTION

[0025] The present utility model will be further described below in conjunction with the accompanying drawings and specific embodiments.

[0026] Figure 1 is a perspective view of a base of the present utility model. In the embodiment shown in Figure 1 the base includes a positioning ring 1, an upper base 2, and a lower base 3. Among them, the lower base 3 is located between the positioning ring 1 and the upper base 2. The positioning ring 1 is an annular ring, which is used to connect with the outer ring burner cap 4 and is used to position the outer ring burner cap 4. The upper base 2 is arranged on the lower base 3 and is used to install the central burner cap 6. The lower base 3 is used to connect and fix the positioning ring 1 and the upper base 2 together.

[0027] Specifically, in order to extend the service life while reducing costs, the positioning ring 1 is made of copper. The flame blown out by the outer ring burner cap 4 located on the positioning ring 1 will burn the positioning ring 1. The copper positioning ring 1 has good heat resistance. Stainless steel will undergo annealing during long-term burning, causing rust and short service life, while the copper positioning ring 1 will not undergo annealing and has a long service life. At the same time, at least one of the upper base 2 and the lower base 3 is selected as a high-temperature resistant product, that is, at least one of the upper base 2 and the lower base 3 does not use copper but is replaced by other high-temperature resistant products. The price of other high-temperature resistant products is lower than that of copper. Since the temperature at which the upper base 2 and the lower base 3 are burned by the flame is lower than that of the positioning ring 1, this can not only reduce costs but also ensure high temperature resistance and improve reliability, such as metal products like aluminum products and stainless steel products. Although the upper base 2 is installed with a central burner cap, the temperature at which the flame at the central burner cap burns the upper base 2 is not as high as that at the positioning ring 1. Using other high-temperature resistant products instead can meet the use requirements.

[0028] Figure 2 is a main view sectional view of a base of the present utility model. As shown in Figure 2In the illustrated embodiment, when the upper base 2 and the lower base 3 are made of different materials, the upper base 2 and the lower base 3 are of a split structure. Since two objects made of different materials cannot be formed into one integral body, it is necessary to fixedly connect the upper base 2 and the lower base 3 together. Different materials mean that the materials of the upper base 2 and the lower base 3 are different. For example, when the upper base 2 is made of stainless steel, the lower base 3 is made of a high-temperature resistant product other than stainless steel, which can be a copper product, an aluminum product or other high-temperature resistant products. Specifically, the upper base 2 and the lower base 3 are detachably connected, which is convenient for installation and disassembly. When one of the upper base 2 and the lower base 3 is damaged, only one of them needs to be replaced, which greatly reduces the cost and extends the service life. Further, the upper base 2 and the lower base 3 are detachably connected by bolts. A first threaded hole 220 is provided on the bottom surface of the upper base 2 along the circumferential direction, and a first through hole 310 corresponding to the first threaded hole 220 is provided on the upper surface of the lower base 3. The bolt passes through the first through hole 310 and is screwed into the first threaded hole 220 to fix the upper base 2 and the lower base 3 together.

[0029] Figure 3 is a perspective view of the upper base of a base of the present utility model, as Figure 3 In the illustrated embodiment, when the upper base 2 and the lower base 3 are detachably connected, a plurality of downward-opening slots 210 are provided on the bottom surface of the upper base 2. When the upper base 2 is fixed on the lower base 3, an air supply channel 5 is formed between the slots 210 and the upper surface of the lower base 3. The gas enters the annular cavity surrounded by the lower base 3, the positioning ring 1, the outer ring burner cover 4 and the upper base 2 through the air supply channel 5, and thus the flame is ejected from the air outlet holes 410 of the outer ring burner cover 4. The air supply channel 5 is formed by the slots 210 and the upper surface of the lower base 3, and there is no need to additionally process the air supply channel 5, so the processing difficulty is low and the production cost is reduced.

[0030] In addition, when the upper base 2 and the lower base 3 are made of the same material, the upper base 2 and the lower base 3 are of an integral structure, which is convenient for overall manufacturing and does not require the upper base 2 and the lower base 3 to be separately manufactured, greatly reducing the cost, especially during mass production.

[0031] In addition, the positioning ring 1 and the lower base 3 can also be made of the same material, so that the positioning ring 1 and the lower base 3 can be an integral body, but the upper base 2 cannot be made of the same material as the positioning ring 1. There is also a case where the positioning ring 1 and the upper base 2 can be made of the same material, but the lower base 3 cannot be made of the same material as the positioning ring 1.

[0032] Figure 4 is a main view sectional view of the lower base and the positioning ring of a base of the present utility model, as Figure 3In the illustrated embodiment, the lower base 3 is detachably connected to the positioning ring 1. Specifically, the lower base 3 and the positioning ring 1 are also connected by bolts. The positioning ring 1 is provided with a plurality of second through holes 120 in the circumferential direction, and the lower base 3 is provided with second threaded holes 320 corresponding to the second through holes 120. The bolts pass through the second through holes 120 and are screwed into the second threaded holes 320.

[0033] Furthermore, Figure 5 is the front view sectional view of a base positioning ring of the present utility model. As Figure 5 shown in the illustrated embodiment, an annular plate 110 is provided on the inner side wall of the positioning ring 1. The center of the annular plate 110 and the center of the positioning ring 1 are on the same vertical line. The annular plate 110 is provided with a plurality of second through holes 120 in the circumferential direction. The lower base 3 is provided with second threaded holes 320 corresponding to the second through holes 120. The bolts pass through the second through holes 120 and are screwed into the second threaded holes 320. Due to the provision of the annular plate 110, the contact area between the positioning ring 1 and the lower base 3 is large, the connection is more firm, and it is also convenient to set the through holes, so that the lower base 3 and the positioning ring 1 can be connected without setting on the positioning ring 1 itself. At the same time, an annular protrusion is provided on the outer side surface of the lower end of the lower base 3, and the second threaded hole 320 is provided on this annular protrusion. Specifically, when installing, the upper surface of the annular protrusion abuts against the bottom surface of the annular plate 110. At this time, the outer side surface of the lower base 3 abuts against the inner side wall of the annular plate 110 to play a role of positioning and limiting, which is convenient for installation. Specifically, the second threaded hole 120 is a through hole, and the annular burner cap 4 is provided with a third threaded hole corresponding to the second threaded hole 120. The bolts pass through the second through holes 120 and are sequentially screwed into the second threaded holes 120 and the third threaded holes, so that the positioning ring 1, the lower base 3 and the outer ring burner cap 4 can be fixed together at the same time, and the installation and disassembly are convenient, and the structure is simple.

[0034] Figure 6 is the perspective view of a base of the present utility model with an outer ring burner cap installed. As Figure 6 shown in the illustrated embodiment, the burner includes a positioning ring 1, an upper base 2, a lower base 3, an outer ring burner cap 4 and a central burner cap. The upper base 2, the lower base 3 and the positioning ring 1 are arranged in sequence from top to bottom. The outer ring burner cap 4 is arranged on the positioning ring 1. An annular cavity is formed inside the outer ring burner cap 4, the positioning ring 1, the lower base 3 and the upper base 2. One end of the air supply channel 5 is communicated with the annular cavity, and the other end is communicated with the gas pipe. The gas in the gas pipe enters the annular cavity through the air supply channel 5 and finally sprays out from the fire holes 410. Specifically, the fire holes 410 of the outer ring burner cap 4 can be arranged on the outer side surface of the annular burner cap 4, or can be arranged on the inner side surface of the annular burner cap 4, or can be arranged on both the inner and outer side surfaces of the annular burner cap 4.

[0035] Specifically, the principle of the present utility model is to divide the base into a positioning ring 1, a lower base 3, and an upper base 2. The outer ring burner cap 4 is installed on the positioning ring 1, and the flame outlet holes on the outer ring burner cap 4 are close to the positioning ring 1. The positioning ring 1 is subjected to a relatively high temperature of flame burning. The positioning ring 1 is made of copper products, which are more heat-resistant, will not produce annealing phenomenon, and have a long service life. At the same time, since the lower base 3 and the upper base 2 are subjected to a relatively lower temperature of flame burning, at least one of the upper base 2 and the lower base 3 is made of heat-resistant products, such as aluminum products, with low processing difficulty and greatly reduced cost.

[0036] Taking the positioning ring 1 as a copper product and the upper base 2 and the lower base 3 as aluminum products as an example, aluminum is much lower in price than copper, which reduces the cost. Aluminum products are easy to process and meet the use requirements. The copper-based positioning ring 1 will not produce annealing phenomenon during a long-term burning process. The positioning ring 1 is detachably connected to the lower base 3, and the upper base 2 and the lower base 3 are detachably connected. The positioning ring 1, the lower base 3, and the upper base 2 can be interchanged. If one of them is damaged, only the damaged part needs to be replaced, which prolongs the service life.

[0037] On the basis of the above solution, if various modifications or deformations to the present utility model do not depart from the spirit and scope of the present utility model, and if these modifications and deformations fall within the scope of the claims of the present utility model and equivalent technical scope, then the present utility model also intends to include these modifications and deformations.
