Description

Technical Field

[0001] The utility model relates to a gas stove accessory, in particular to a gas stove burner. Background Art

[0002] As the core component of household and industrial gas equipment, the gas stove burner is responsible for mixing and burning gas and air. Existing gas stove burners are usually composed of multiple parts, including a flame distribution cover, a gas mixing ring, a gas guide pipe, etc. Among them, the flame distribution cover is located above the gas mixing ring, and the gas is evenly distributed through the fire holes on it to achieve a stable flame.

[0003] In traditional designs, the flame divider cover and the burner head adopt a split and detachable structure. This design mainly takes into account the convenience of the following aspects: 1. During use, the flame divider cover of the gas stove burner will accumulate dirt and combustion residues. The detachable flame divider cover design allows users to easily remove the flame divider cover for cleaning and maintain the good performance of the burner.

[0004] 2. When the ignition cover is damaged or fails, the user can replace the ignition cover alone without replacing the entire burner, saving maintenance costs.

[0005] However, although this split and detachable design provides convenience to a certain extent, it also exposes some serious defects in actual application, which are specifically manifested in the following aspects:

[0006] 1. Risk of loss during transportation: Since the flame divider cover and the burner head are independent components, the gas stove burner needs to be packaged and transported after manufacturing. During transportation, the flame divider cover is easily separated from the burner head due to vibration, collision, etc., resulting in the loss of the flame divider cover. This will not only cause chaos inside the packaging box, but also increase the management difficulty and cost of the manufacturer during the packaging and transportation process.

[0007] 2. Inconvenience for users: For end users, the gas stove burner they received may be missing the flame distributor cap due to loss during transportation, which makes it impossible to install and use it normally. Users need to contact the manufacturer or dealer to purchase a new flame distributor cap, which increases the cost and time cost of use. In addition, when users install the flame distributor cap by themselves, improper operation may cause unstable installation, affecting the normal operation of the burner.

[0008] 3. The correct installation of the flame distribution cover is directly related to the safety performance of the gas stove burner. If the flame distribution cover is not firmly connected to the gas mixing ring, it may cause gas leakage or unstable flame, increasing the safety risk during use. Therefore, it is necessary to make further improvements to it. Utility Model Content

[0009] The purpose of the utility model is to overcome the shortcomings of the existing technology and provide a gas furnace burner with a simple structure and easy use. Through innovative structural design, the fire distribution cover and the gas mixing ring are firmly connected as one, avoiding the problems of the fire distribution cover being lost and the inconvenience of installation in the traditional design, and can effectively improve the safety and stability of the product.

[0010] The purpose of the utility model is achieved in the following way: a gas furnace burner, which includes an outer ring gas mixing ring and an inner ring gas mixing ring, the two rings are connected and communicated with each other through an air guide pipe, the outer ring gas mixing ring is covered with an outer ring fire cover, and the inner ring gas mixing ring is covered with an inner ring fire cover, the upper end face of the outer ring fire cover is in an inverted "V" shape and is provided with an inner bevel and an outer bevel, and the outer bevel is provided with a plurality of vertically distributed strip fire holes; the lower end of the inner bevel extends downwardly to have an inner connecting ring covering the inner circle of the outer ring gas mixing ring, the lower end of the outer bevel extends downwardly to have an outer connecting ring, and the outer connecting ring is provided with an outwardly convex clamping ring, correspondingly, a clamping platform is provided on the outer cylindrical surface of the outer ring gas mixing ring, the clamping ring is clamped on the clamping platform, and the outer ring fire cover and the outer ring gas mixing ring are fixed as a whole.

[0011] Furthermore, the strip-shaped fire holes are provided with upper and lower circles, which are arranged in a circular shape on the outer inclined surface, and the upper and lower circles of strip-shaped fire holes are staggered in left and right distribution.

[0012] Furthermore: among the strip-shaped fire holes, the height of the fire holes located in the upper circle is greater than the height of the fire holes located in the lower circle.

[0013] Furthermore: the cross section of the clamp ring is set in a trapezoidal shape, and correspondingly, the cross section of the clamping platform is also set in a trapezoidal shape.

[0014] Furthermore, a mixing disk is installed in the outer ring mixing ring, and the mixing disk divides the outer ring mixing ring into an upper mixing chamber and a lower mixing chamber. A plurality of air guide grooves are opened on the mixing disk to conduct the upper mixing chamber and the lower mixing chamber.

[0015] Furthermore, the air guide grooves are through grooves arranged on the air mixing disk, and the air guide grooves are distributed in an annular array on the air mixing disk.

[0016] Furthermore, a guide plate is obliquely extended upward on one side of the air guide groove, and the guide plate is formed by stamping the mixing plate body material upward.

[0017] Furthermore: the mixing plate is provided with an air avoidance groove at the position corresponding to the air guide pipe.

[0018] The beneficial effects of the utility model are: 1. Simple structure, low production cost and improved market competitiveness.

[0019] 2. By fixing the outer ring fire cover and the outer ring gas mixing ring as a whole, the loosening and falling problems caused by the traditional split detachable structure are effectively avoided. This design ensures that the fire cover remains stable during production, transportation and use, eliminates the risk of losing the fire cover, and improves the overall stability of the product.

[0020] 3. The outer ring fire cover and the outer ring gas mixing ring of the present invention are fixed by an outer connecting ring and a clamping ring. During production, the manufacturer uses a mold or a rotary riveting machine to squeeze and fasten them together, which can effectively ensure that the two can always be in a firmly and stably connected state after assembly.

[0021] 4. The upper end surface of the outer ring fire cover is in an inverted "V" shape, with an inner bevel and an outer bevel. The vertical strip fire holes on the outer bevel are reasonably distributed, ensuring the uniform distribution and full combustion of the gas. In particular, the upper and lower circles of the strip fire holes are staggered left and right, further optimizing the stability of the flame and the combustion efficiency.

[0022] 5. By setting strip fire holes with different heights in the upper and lower circles, multi-level control of the flame is achieved. The height of the upper circle fire holes is greater than that of the lower circle fire holes, making the flame height more diverse, which can better adapt to different cooking needs and improve the applicability and flexibility of the burner.

[0023] 6. The design of the clamping ring and clamping platform with a trapezoidal cross section ensures the firm connection between the outer ring fire cover and the outer ring mixing ring, effectively preventing the separation and loosening caused by vibration or collision. This design greatly improves the safety performance of the gas furnace burner and reduces the possibility of safety hazards during use.

[0024] 7. The mixing disk installed in the outer mixing ring effectively optimizes the distribution and mixing of airflow by dividing the mixing ring into an upper mixing chamber and a lower mixing chamber and setting air guide grooves to achieve conduction. This design can improve the mixing efficiency of gas and air, and improve combustion efficiency and stability. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION

[0031] The utility model is further described in detail below in conjunction with the accompanying drawings. A gas furnace burner, comprising an outer ring gas mixing ring 1 and an inner ring gas mixing ring 2, the two rings are connected and communicated with each other through an air guide pipe 3, the outer ring gas mixing ring 1 is covered with an outer ring fire cover 4, the inner ring gas mixing ring 2 is covered with an inner ring fire cover 5, the upper end face of the outer ring fire cover 4 is in an inverted "V" shape and is provided with an inner bevel 41 and an outer bevel 42, the outer bevel 42 is provided with a plurality of vertically distributed strip fire holes 46; an inner connecting ring 43 is extended downward from the lower end of the inner bevel 41 and covers the inner ring of the outer ring gas mixing ring 1, an outer connecting ring 44 is extended downward from the lower end of the outer bevel 42, the outer connecting ring 44 is provided with an outwardly protruding clamping ring 45, correspondingly, a clamping platform 11 is provided on the outer cylindrical surface of the outer ring gas mixing ring 1, the clamping ring 45 is clamped on the clamping platform 11, and the outer ring fire cover 4 and the outer ring gas mixing ring 1 are fixed as a whole.

[0032] In one embodiment, the strip-shaped fire holes 46 are provided with upper and lower circles, which are arranged in a circular shape on the outer inclined surface 42, and the upper and lower circles of strip-shaped fire holes are staggered in left and right directions.

[0033] In one embodiment, among the strip-shaped fire holes 46, the height of the fire holes located in the upper circle is greater than the height of the fire holes located in the lower circle.

[0034] In one embodiment, the cross section of the clamping ring 45 is arranged in a trapezoidal shape, and correspondingly, the cross section of the clamping platform 11 is also arranged in a trapezoidal shape.

[0035] In one embodiment, a mixing disk 6 is installed in the outer ring mixing ring 1, and the mixing disk 6 divides the outer ring mixing ring 1 into an upper mixing chamber and a lower mixing chamber. A plurality of air guide grooves 61 are opened on the mixing disk 6 to connect the upper mixing chamber and the lower mixing chamber.

[0036] In one embodiment, the air guide grooves 61 are through grooves provided on the mixing plate 6 , and the air guide grooves 61 are distributed in an annular array on the mixing plate 6 .

[0037] In one embodiment, a guide plate 62 is obliquely extended upward from one side of the air guide groove 61 , and the guide plate 62 is formed by stamping the main body material of the mixing plate 6 upward.

[0038] In one embodiment, the mixing plate 6 is provided with an air avoidance groove 63 at a position corresponding to the air guide pipe 3 .

[0039] Working principle: When in use, the gas enters the outer gas mixing ring 1 and the inner gas mixing ring 2 from the ejector pipe of the burner through the gas guide pipe 3, and conducts between the two rings. This design ensures smooth flow of gas between the two rings and effectively avoids air flow turbulence.

[0040] Among them, the mixing disc 6 installed in the outer ring mixing ring 1 divides it into an upper mixing chamber and a lower mixing chamber, further optimizing the distribution of airflow. The air guide groove 61 on the mixing disc ensures the airflow conduction between the upper mixing chamber and the lower mixing chamber, so that the gas and air can be fully mixed when they pass through the air guide groove. In addition, the air guide grooves are arranged in a circular array, and the guide plate 62 extending obliquely upward on one side is formed by stamping upward from the mixing disc body material, effectively guiding the airflow and improving the mixing efficiency.

[0041] The mixed gas flows out from the outer ring gas mixing ring 1 and enters the combustion zone through the strip fire holes 46 on the outer inclined surface 42. The upper end surface of the outer ring fire cover 4 is in an inverted "V" shape, and is provided with an inner inclined surface 41 and an outer inclined surface 42, so that the gas can be evenly distributed. In particular, the strip fire holes on the outer inclined surface are vertically distributed, which ensures the stability and uniformity of the flame.

[0042] The strip-shaped fire holes are divided into two circles, one above the other, and are staggered left and right. This design can form multiple levels of flame height, making the combustion more complete and the flame more stable, which can meet different cooking needs. The height of the upper circle of fire holes is greater than that of the lower circle of fire holes, making the distribution of flames at different levels more reasonable.

[0043] Among them, an outer connecting ring 44 extends from the lower end of the outer inclined surface 42 of the outer ring fire cover 4, on which a convex clamping ring 45 is provided, corresponding to the clamping platform 11 on the outer cylindrical surface of the outer ring gas mixing ring 1. The cross section of the clamping ring is designed in a trapezoidal shape, which matches the trapezoidal cross section of the clamping platform, so that the clamping ring can be firmly clamped on the clamping platform, thereby fixing the outer ring fire cover 4 and the outer ring gas mixing ring 1 as a whole, ensuring the stability of the structure. This design effectively avoids the risk of falling off and loss caused by the traditional split detachable structure.

[0044] Compared with the traditional technology, the fixed design of the outer ring fire cover 4 and the outer ring mixing ring 1 in this case not only improves the structural stability of the burner, but also simplifies the installation and maintenance process. Users do not need to worry about improper installation of the fire cover or loss of the fire cover during transportation, which improves the convenience of use. The fixed design of the outer ring fire cover and the outer ring mixing ring avoids the risk of loosening and loss of the fire cover in the traditional design, ensuring the stability of the burner during production, transportation and use.

[0045] Through the above technical means, the present invention has significant advantages in improving burner performance, ease of use and safety, overcomes many defects of traditional gas stove burners, and has broad application prospects.

[0046] 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.
