Description

Technical Field

[0001] This utility model relates to the field of burner technology, and in particular to an upper air intake burner. Background Technology

[0002] Burners typically have top-intake or bottom-intake configurations. In top-intake burners, the injector tube is concealed directly beneath the burner. Due to burner size limitations, the injector tube is shorter, resulting in poor injection capability. This necessitates increasing the relative height of the pot support, leading to a higher overall stove height. This significantly impacts thermal efficiency. Furthermore, water droplets on the injector tube can easily extinguish the flame, further reducing burner efficiency. To address these issues, a solution is proposed below. Utility Model Content

[0003] The purpose of this invention is to provide an upward-intake burner that has the advantages of preventing flame extinguishing and high combustion efficiency.

[0004] The above-mentioned technical objective of this utility model is achieved through the following technical solution: A top-intake burner includes a base with a burner seat on top. Several legs are fixed to the bottom of the burner seat, forming an air intake channel between the legs and the upper part of the burner seat. An outer ring fire chamber is provided on the inner side of the burner seat, and several outer ring fire holes are opened on the top of the burner seat. A detachable outer ring fire cover is also connected to the top of the burner seat. Several connecting posts are fixed between the inner walls of the burner seat, and an inner ring fire seat is fixed between the other ends of the connecting posts. A supporting boss is fixed to the inner wall of the inner ring fire seat, and a detachable inner ring fire cover is connected to the top of the inner ring fire seat, with the lower end of the inner ring fire cover abutting against the upper end of the supporting boss. The inner ring burner cover has several inner ring fire holes on its outer wall. The base has an inner ring air inlet pipe and two outer ring air inlet pipes. The bottom of the stove base has two outer ring grooves. The upper ends of the two outer ring air inlet pipes pass through the outer ring grooves and are located inside the outer ring fire chamber. The upper ends of the two outer ring air inlet pipes are also connected to outer ring ejector pipes. Several baffles are fixed inside the outer ring fire chamber. The baffles are all inclined. The bottom of the inner ring burner base has an inner ring groove. The upper ends of the inner ring air inlet pipes pass through the inner ring grooves and are located inside the inner ring burner base. The upper ends of the inner ring air inlet pipes are also connected to inner ring main pipes. Several inner ring ejector pipes are connected to the outside of the inner ring main pipes.

[0005] Preferably, the upper end of the base is also provided with a support base, and the stove base is located inside the support base. Several positioning blocks are fixedly provided at the bottom of the support base, and several positioning grooves are provided at the upper end of the base. The lower ends of the several positioning blocks are respectively located in the positioning grooves, and several support frames are fixedly provided at the top of the support base.

[0006] Preferably, the base is provided with an inner ring connecting pipe at its lower part, and the inner ring connecting pipe is connected to the inner ring air intake pipe. The base is also provided with an outer ring connecting pipe at its lower part, and the outer ring connecting pipe is connected to two outer ring air intake pipes.

[0007] Preferably, the lower end of the outer ring flame cap is fixedly provided with an embedding seat, and the embedding seat is slidably embedded in the outer ring flame cavity.

[0008] Preferably, an outer ring check portion is formed on each of the two outer ring ejector tubes, and an inner ring check portion is formed on each of the several inner ring ejector tubes.

[0009] Preferably, the upper end of the base is also provided with an ignition needle and an ion sensing needle.

[0010] The beneficial effects of this utility model are as follows: 1. In use, the gas in the outer ring burner can be ejected through several outer ring burner holes. After igniting the gas, the outer ring flame can be ejected from several outer ring burner holes, thus enabling combustion and cooking. Similarly, the gas in the inner ring burner can be ejected through several inner ring burner holes. The inner ring flame can be ignited with the help of an ignition needle, thus enabling combustion. The outer ring flame can also be ignited with the help of the inner ring flame. Therefore, users can choose to use both inner and outer ring flames or only the inner ring flame for combustion and cooking.

[0011] 2. Users can inject gas into the two outer ring air inlet pipes. The gas can then be transported to the outer ring fire chamber through the two outer ring air inlet pipes. The gas in the two outer ring air inlet pipes can be ejected through the two outer ring ejector pipes respectively. The gas can flow along several baffles, which increases the flowability of the gas, so that the gas can be quickly distributed in the outer ring fire chamber. This further improves the combustion efficiency and uniformity of the outer ring flame. The outer ring check valve prevents water droplets from flowing into the outer ring ejector pipe and causing the flame to go out.

[0012] 3. Users can inject gas into the inner ring intake pipe, and the gas can be transported to the inner ring main pipe through the inner ring intake pipe. Then it can be ejected into the inner ring burner through several inner ring ejector pipes. The inner ring check valve can prevent water droplets from flowing into the inner ring ejector pipe and causing the flame to go out. Attached Figure Description
