Description

Technical Field

[0001] This utility model relates to the field of commercial stove accessories technology, and more specifically to a natural aspiration premixed stove head. Background Art

[0002] Commercial stoves are primarily designed for kitchen use in hotels and construction projects. These commercial stoves require complete combustion of gas and have stringent environmental requirements. Furthermore, chefs often splash water and produce food residue while cooking, which can clog the gas vents on the combustion surface, leading to incomplete combustion. Therefore, cleanliness and drainage are essential functions for commercial kitchen stoves. Many stoves on the market are non-disassembly and are relatively traditional, making them impossible to clean. Consequently, incomplete combustion and red flames are common during combustion. Utility Model Content

[0003] The main purpose of this utility model is to solve the above-mentioned problems and provide an air-suction premixed burner head.

[0004] The technical solution adopted by this utility model is as follows: a naturally aspirated premixed burner head, including an air inlet pipe, a nozzle designed at the front end of the air inlet pipe, an air guide pipe designed in the opposite position of the nozzle, an adjusting thread and a fixing plate that rotates in and out of the air inlet pipe near the nozzle, the other end of the fixing plate being fixed to the bottom of the air guide pipe, an adjusting pipe with an interference fit on the inner wall of the air guide pipe, the adjusting pipe being close to the inner wall of the air guide pipe, the front section of the adjusting pipe being designed with an outward opening shape, the adjusting pipe being able to be stretched in and out of the air guide pipe by external force, the other end of the air guide pipe away from the adjusting pipe being designed with an embedded elbow, the other end of the elbow being designed with a lower seat, the surface of the lower seat being designed with an upper cover that matches its shape, and the inner wall of the upper cover being evenly designed with through gas holes.

[0005] Furthermore, a tinder position is designed on one side edge of the lower seat, and a tinder hole is designed on the inner wall of the upper cover at the corresponding position of the tinder position.

[0006] The process of using this utility model patent involves transporting gas through an intake pipe to a guide pipe. Gas pressure exists at the nozzle of the intake pipe, and a gap exists between the nozzle and the guide pipe, creating air pressure. This pressure and air pressure accelerate the mixing of gas and air into the guide pipe. Simultaneously, an adjusting screw in the middle of the intake pipe can adjust the direction of the nozzle and the distance between the nozzle and the adjusting pipe. The adjusting pipe can also be extended or retracted on the inner wall of the guide pipe, thereby adjusting the distance between the nozzle and the adjusting pipe and regulating the gas flow rate. Under external air pressure and the opening of the adjusting pipe, the mixing of air and gas is accelerated, increasing the flow rate of the mixed gas. Under the action of the adjusting pipe, the mixed gas is drawn into the guide pipe, where it flows in a ring within the guide pipe. The gas is then transferred through the guide pipe to the lower seat above the bend, and finally, the gas passes through the lower seat to the gas hole on the upper cover for combustion on the surface.

[0007] The beneficial effects of this utility model are as follows: the nozzle sprays high-pressure gas, which allows the gas and air to burn completely, avoiding waste from the burner head. At the same time, the gas flow rate and velocity can be adjusted, and the air inlet pipe can be adapted to different installations depending on the direction of the adjustment thread rotation.

[0016] Please see Figures 1 to 4 A preferred embodiment of this utility model is a naturally aspirated premixed burner head, comprising an air inlet pipe 1. A nozzle 12 is designed at the front end of the air inlet pipe 1. An air guide pipe 2 is designed opposite the nozzle 12, with a gap between the nozzle and the nozzle. The air inlet pipe 1 has an adjusting thread 13 and a fixing plate 14 that rotates in and out with the thread near the nozzle 12. A manual knob on the air inlet pipe 1 allows for adjustment of the direction of the air inlet pipe, making installation more convenient for consumers. The other end of the fixing plate 14 is fixed to the bottom of the air guide pipe 2. An adjusting pipe 21 with an interference fit is designed on the inner wall of the air guide pipe 2, and the adjusting pipe 21 is tightly fitted to the air guide pipe 2. The inner wall of the regulating pipe 21 has an outwardly flared opening 211 at the front. The close fit between the regulating pipe and the outwardly flared opening allows the gas from the nozzle to seep out from the edge of the regulating pipe. The regulating pipe 21 can be stretched into and out of the air guide pipe 2 by external force. The other end of the air guide pipe 2 away from the regulating pipe 21 has an embedded elbow 3. The other end of the elbow 3 has a lower seat 4. The elbow 3 is designed for horizontal ventilation, which can convert vertical gas to horizontal design, which is convenient for different installation needs of consumers. The surface of the lower seat 4 has an upper cover 5 that matches its shape. The inner wall of the upper cover 5 has gas through holes 51 evenly designed around its perimeter.

[0017] Furthermore, a tinder position 41 is designed on one side edge of the lower seat 4, and a tinder hole 52 is designed on the inner wall of the upper cover 5 at the corresponding position of the tinder position 41.

[0018] The process of using this utility model patent is as follows: Gas is delivered to air duct 2 through air inlet pipe 1. Gas pressure exists at nozzle 12 of air inlet pipe 1. There is a gap between nozzle 12 and air duct 2, which creates air pressure. The pressure and air pressure accelerate the mixing of gas and air into air duct 2. At the same time, the adjusting thread 13 in the middle of air inlet pipe 1 can adjust the direction of air inlet pipe 1 and the distance between nozzle 12 and adjusting pipe 21. Meanwhile, adjusting pipe 21 can be extended and retracted on the inner wall of air duct 2, thereby adjusting the distance between nozzle 12 and adjusting pipe 21 to regulate the gas flow rate. When the gas is under external air pressure and the opening of adjusting pipe 21, the mixing of air and gas is accelerated, and the flow rate of the mixed gas increases. Under the action of adjusting pipe 21, it is drawn into air duct 2. The mixed gas flows in a ring inside air duct and is transmitted to the lower seat 4 above elbow 3 through air duct 2. Finally, the gas reaches the gas hole 51 of upper cover 5 through lower seat 4 and is transmitted to the surface for combustion.

[0019] The beneficial effects of this utility model are as follows: the nozzle sprays high-pressure gas, which allows the gas and air to burn completely, avoiding waste from the burner head. At the same time, the gas flow rate and velocity can be adjusted, and the air inlet pipe can be adapted to different installations depending on the direction of the adjustment thread rotation.

[0020] The embodiments and accompanying drawings of this utility model are only for illustrating the design concept of this utility model, and the protection scope of this utility model should not be limited to this embodiment.

[0021] As can be seen from the above description, the design objective of this utility model can be effectively implemented. The embodiments illustrate the objective, functionality, and structural subject matter of this utility model, and include other equivalent substitutions.

[0022] Therefore, the rights and obligations of this utility model include other equivalent implementations, and the specific scope of rights is as described in the claims.
