Description
Technical Field
[0001] The utility model relates to the technical field of gas stoves, in particular to a burner head for a gas stove. Background Art
[0002] As an indispensable appliance in the kitchen, the safety and efficiency of gas stoves have always been of great concern to users and manufacturers. In the traditional design of gas stoves, ignition pins and thermocouples are key components for automatic ignition and safety monitoring. However, there are certain design defects in the installation and protection methods of these components, which not only affects the reliability of gas stoves, but also increases maintenance costs.
[0003] In existing gas stove technology, ignition pins and thermocouples are usually installed directly on the periphery of the burner or near the fire source. This design exposes these components to high temperatures, oil smoke, and splashes that may be generated during cooking. Specifically, the ignition pin is responsible for generating sparks to ignite the gas, while the thermocouple is used to monitor the flame status to ensure that the gas supply can be quickly cut off to ensure safety after the flame is extinguished. Since these components are located in a more conspicuous position on the stove surface, they are easily physically damaged by collisions with cooking utensils or careless operation. In addition, long-term exposure to high temperatures will cause material degradation of the components, affecting their functional stability and service life.
[0004] Therefore, the current design still has some protection deficiencies, and the ignition needle and thermocouple often face rapid wear or damage due to the lack of effective protection measures. This situation not only leads to frequent maintenance needs and increases the economic burden of users, but may also bring safety hazards when gas leaks are not detected in time, so it is necessary to make further improvements. Utility Model Content
[0005] The purpose of the utility model is to overcome the shortcomings of the prior art and provide a burner head for a gas stove which has a simple structure, is easy to use, has high combustion efficiency, can effectively extend the service life of the equipment, and improves its overall safety and reliability.
[0006] The utility model aims to achieve the following objectives: a burner head for a gas stove, comprising a main body, a first gas mixing groove and a second gas mixing groove are arranged on the top of the main body, and are respectively connected to a first ejector and a second ejector, and the end faces of the outer circles of the first gas mixing groove and the second gas mixing groove are arranged with a plurality of concave combustion grooves, and the surfaces thereof are respectively covered with a first fire distribution cover and a second fire distribution cover;
[0007] The outer cylinder of the second gas mixing tank is provided with a first concave mounting groove and a second mounting groove, and the ignition needle and the thermocouple are respectively installed in the first mounting groove and the second mounting groove. After the second ignition distributor cover is installed, the ignition needle and the thermocouple are covered at the lower end of the second ignition distributor cover.
[0008] Specifically: the upper end surfaces of the notches of the first gas mixing groove and the second gas mixing groove are arranged in an inclined shape with the outer side higher and the inner side lower.
[0009] Specifically: the combustion groove is a trapezoidal groove which is wide at the top and narrow at the bottom, and the trapezoidal groove is arranged to penetrate the upper end surface of the outer circle of the first gas mixing groove and the second gas mixing groove.
[0010] Specifically: the combustion grooves are arranged in a circular array on the first gas mixing groove and the second gas mixing groove, and the groove bottoms of two adjacent combustion grooves are arranged in a high-low staggered manner.
[0011] Specifically: the first mounting groove and the second mounting groove are concave arc grooves.
[0012] The beneficial effects of the utility model are: 1. Simple structure, low production cost and improved market competitiveness.
[0013] 2. In the present invention, the ignition needle and the thermocouple are cleverly installed in the concave mounting groove of the second gas mixing tank and covered by the second ignition distribution cover. Compared with the common exposed installation of the ignition needle and the thermocouple in the traditional gas stove, this configuration significantly improves the protection of these sensitive components. The ignition needle and the thermocouple covered under the second ignition distribution cover not only avoid direct contact with high temperature, oil smoke and accidental splashing, but also reduce the damage that may be caused by physical collisions in daily use. This design significantly extends the service life of these key components and reduces the frequency and cost of maintenance.
[0014] 3. The design of the combustion tank also optimizes the mixing efficiency of gas and air and the distribution of flames. The combustion tank adopts a trapezoidal structure that is wide at the top and narrow at the bottom, and is distributed in a circular array. The high and low staggered design enhances the coverage and uniformity of the flame. This design improves thermal efficiency and makes the cooking process more economical and efficient.

[0019] The utility model is further described in detail below with reference to the accompanying drawings. A burner head for a gas stove, characterized in that it comprises a main body 1, a first gas mixing groove 2 and a second gas mixing groove 3 are arranged on the top of the main body 1, and are respectively connected to a first ejector 4 and a second ejector 5, and the end faces of the outer circles of the first gas mixing groove 2 and the second gas mixing groove 3 are arranged with a plurality of concave combustion grooves 6, and the surfaces thereof are respectively covered with a first fire distribution cover 7 and a second fire distribution cover 8;
[0020] The outer cylinder of the second gas mixing tank 3 is provided with a concave first mounting groove 9 and a second mounting groove 10, and the ignition needle 11 and the thermocouple 12 are respectively installed in the first mounting groove 9 and the second mounting groove 10. After the second ignition cover 8 is installed, the ignition needle 11 and the thermocouple 12 are covered at the lower end of the second ignition cover 8.
[0021] In one embodiment, the upper end surfaces of the notches of the first gas mixing groove 2 and the second gas mixing groove 3 are arranged in an inclined shape with the outer side higher and the inner side lower.
[0022] In one embodiment, the combustion groove 6 is a trapezoidal groove that is wide at the top and narrow at the bottom, and the trapezoidal groove passes through the upper end surface of the outer circle of the first gas mixing groove 2 and the second gas mixing groove 3.
[0023] In one embodiment, the combustion grooves 6 are arranged in a circumferential array on the first gas mixing groove 2 and the second gas mixing groove 3, and the groove bottoms of two adjacent combustion grooves 6 are arranged in a staggered manner.
[0024] In one embodiment, the first mounting groove 9 and the second mounting groove 10 are concave arc grooves.
[0025] Working principle: The burner head for a gas stove of the present invention comprises a main body 1, and a first gas mixing groove 2 and a second gas mixing groove 3 are arranged on the top of the main body. The two gas mixing grooves are respectively connected to the first ejector 4 and the second ejector 5, and are used to guide and accelerate the mixed flow of air and gas, thereby improving the mixing efficiency and the combustion performance.
[0026] It should be noted that the design of the gas mixing groove allows the gas and air to be fully mixed before entering the combustion groove. The upper end surface of the groove of the first gas mixing groove 2 and the second gas mixing groove 3 is designed to be inclined with the outer side high and the inner side low. This structure helps to adjust the flow direction and speed of the mixed gas flow and ensure that the mixed gas is evenly distributed to each combustion groove.
[0027] It should be noted that the combustion groove 6 is designed as a trapezoidal groove that is wide at the top and narrow at the bottom. This structure is conducive to the stable diffusion of the flame and the uniform distribution of heat energy. The trapezoidal groove runs through the upper end surface of the outer circle of the first mixing groove and the second mixing groove, increasing the area of the flame contacting the air, thereby improving the combustion efficiency.
[0028] It should be noted that the ignition needle 11 and the thermocouple 12 are respectively installed in the first installation groove 9 and the second installation groove 10, which are concave arc grooves located on the outer cylinder of the second gas mixing groove 3. The installation of the second ignition cover 8 not only provides mechanical protection for the ignition needle and the thermocouple, but also isolates high temperature and oil smoke, prolongs the service life of these key components and reduces the frequency of maintenance.
[0029] Therefore, compared with the traditional technology, this technical solution solves the above technical problems and achieves the following technical effects:
[0030] 1. Improve combustion efficiency: By optimizing the structure of the gas mixing tank and the design of the combustion tank, the present invention effectively improves the mixing efficiency of gas and air and the heat distribution of the flame, making the combustion more complete and reducing energy waste.
[0031] 2. Enhanced equipment safety: The recessed mounting grooves and covering design of the ignition pin and thermocouple significantly improve the protection of these sensitive components, thereby improving the safety of the entire gas stove, especially under continuous use and high load conditions.
[0032] 3. Extend component life and reduce maintenance costs: Since the ignition needle and thermocouple are effectively protected, damage caused by environmental factors and physical damage is reduced, thus reducing the failure rate and maintenance frequency of these components.
[0033] 4. Improve user experience and operational convenience: The optimized design of the burner not only improves cooking efficiency, but also makes the gas stove more convenient for daily maintenance due to its lower failure rate and maintenance requirements.
[0034] Obviously, the above embodiments are merely examples for clear explanation, and are not intended to limit the implementation methods. For those skilled in the art, other different forms of changes or modifications can be made based on the above description. It is not necessary and impossible to list all the implementation methods here. The obvious changes or modifications derived from them are still within the scope of protection of the claims created by the present invention.
