Description
Technical Field
[0001] The utility model belongs to the field of flame distributors, and particularly relates to a new type of three-control and three-airway flame distribution device. Background Art
[0002] The flame distributor is the core component of a gas stove, and its main function is to distribute gas to ensure uniform firepower. It consists of a base and a sleeve. The base is provided with gas holes, and the sleeve is inserted into the base, with control components such as an electro-thermal couple and a solenoid valve inside.
[0003] Currently, most of the commonly used flame distribution devices on the market adopt a two-airway structure. Such devices usually consist of two air pipes, which are respectively connected to the gas source and the target device. Although they can meet the basic usage requirements, there are some obvious deficiencies in actual applications. The two-airway structure can only provide two-way gas shunting and control, resulting in incomplete combustion, generating harmful gases that pollute the environment, inaccurate airway flow control, causing excessive gas consumption, and most of them adopt an assembled structure, that is, the required functions are realized through the assembly of multiple components, and the components cannot be disassembled, replaced, or maintained individually.
[0004] Therefore, a new type of three-control and three-airway flame distribution device is proposed, which has precise control of airway flow, three air pipe channels, high combustion efficiency, and split assembly, facilitating later maintenance. Content of the Utility Model
[0005] In order to overcome the problems of incomplete combustion, inaccurate airway flow control, and inability to disassemble components individually when using the existing flame distributors.
[0006] The technical solution of the utility model is: a new type of three-control and three-airway flame distribution device, including an annular block; the inner wall of the annular block is fixedly connected with a main body housing, the inner wall of the main body housing is fixedly connected with a first circular tube, the left end of the main body housing is penetrated and provided with a first slot and a second slot, a pipe assembly is arranged at the left end of the main body housing, a third slot penetrating the main body housing is opened at the side end of the inner wall of the first circular tube, and the third slot communicates with the second slot. A second circular tube is fixedly connected to the lower end of the inner wall of the main body housing, a fourth slot is opened at the side end of the inner wall of the second circular tube, and the fourth slot communicates with the first slot. A third injection tube located inside the second circular tube is fixedly connected to the lower end of the inner wall of the main body housing, the outer wall of the lower end of the third injection tube has thread teeth, a screw hole is penetrated and opened at the lower end of the inner wall of the main body housing, and the outer wall of the lower end of the third injection tube is adapted to the inner wall of the screw hole. A nozzle bracket is fixedly installed at the lower end of the main body housing through bolts.
[0007] Preferably, by installing the nozzle on the nozzle bracket and fixing the nozzle bracket to the lower end of the main body housing with bolts, the outer wall of the lower end of the third ejector tube is threadedly installed with the inner wall of the screw hole. The fixing plate is threadedly installed at the left end of the main body housing by passing a bolt through the first thread groove, and the air damper is installed inside the groove with bolts. The split-type disassembly and assembly facilitate later replacement and maintenance. Then, the double-ring block is connected to the gas supply pipeline. When the gas reaches the double-ring block, it reaches the area formed by the inner wall of the second circular tube and the outer wall of the third ejector tube through the first air passage, the first ejector tube, the first notch, and the fourth notch, and reaches the area formed by the inner wall of the first circular tube and the outer wall of the second circular tube through the second air passage, the second ejector tube, the second notch, and the third notch. At this time, the gas discharged from the nozzle reaches above the third ejector tube through the third air passage, the screw hole, and the inside of the third ejector tube. The three air passages formed by the main body housing, the second circular tube, and the third ejector tube can fully improve the thermal efficiency and make the combustion more complete.

During use, the induction needle mounting bracket and the ignition needle mounting bracket can ensure that the induction needle and the ignition needle work stably in fixed positions, reducing offsets caused by vibration or external impacts, thereby improving the stability and reliability of the system.
[0011] Preferably, a water tray mounting bracket is fixedly connected to the side wall of the main body housing. A fourth threaded groove is formed through the upper end of the water tray mounting bracket. During use, the water tray mounting bracket is fixed by passing a bolt through the fourth threaded groove. The water tray mounting bracket can be used to collect and discharge liquid, preventing liquid leakage or accumulation inside or around the equipment.
[0012] Preferably, another side wall of the main body housing is fixedly connected with a main body mounting bracket, and a fifth threaded groove is fixedly connected to the upper end of the main body mounting bracket. During use, the main body mounting bracket is fixed by passing a bolt through the fifth threaded groove, with stable structure and simple disassembly and assembly.
[0013] Preferably, the annular diameter of the first circular tube is less than 43 mm. During use, the flow rate and pressure of the gas can be precisely controlled through the size of the annular diameter of the first circular tube, which helps to achieve a more stable gas supply.
[0014] Advantages of the utility model:
[0015] 1. By mounting the nozzle on the nozzle bracket and fixing the nozzle bracket to the lower end of the main body housing with bolts, the outer wall of the lower end of the third ejector tube is threadedly installed with the inner wall of the screw hole, and the fixing plate is threadedly installed on the left end of the main body housing by passing a bolt through the first threaded groove. The damper baffle is installed inside the groove with bolts. The split disassembly and assembly facilitate later replacement and maintenance, solving the problem that the existing burner cannot disassemble and assemble parts individually during use.
[0016] 2. By connecting the double-ring block to the gas supply pipeline, when the gas reaches the double-ring block, it reaches the area formed by the inner wall of the second circular tube and the outer wall of the third ejector tube through the first air passage, the first ejector tube, the first notch and the fourth notch, and reaches the area formed by the inner wall of the first circular tube and the outer wall of the second circular tube through the second air passage, the second ejector tube, the second notch and the third notch. At this time, the gas discharged from the nozzle reaches above the third ejector tube through the third air passage, the screw hole and the inside of the third ejector tube. The three air passages formed by the main body housing, the second circular tube and the third ejector tube can fully improve the thermal efficiency, making the combustion more complete. Since the annular diameter of the first circular tube is less than 43 mm, the flow rate and pressure of the gas can be precisely controlled, which helps to achieve a more stable gas supply, solving the problems of incomplete combustion and inaccurate control of the air passage flow rate in the existing burner during use.
