[0029] In order to further understand the content, features and effects of the present invention, the following embodiments are given as examples and described in detail with reference to the accompanying drawings:

[0030] This utility model discloses a burner, please refer to Figures 1 to 5 ,include:

[0031] The burner 1 has a gas mixing chamber 11 and an air inlet connector 12 connected to the gas mixing chamber 11;

[0032] The air distributor 2 is annular and has a top surface 21. An upper annular wall 22 extends upward from the upper surface of the top surface 21. An air inlet pipe 23 extends downward from the lower surface of the top surface 21. A plurality of air outlet grooves 221 are provided on the top surface of the upper annular wall 22. The air inlet pipe 23 is connected to the lower surface of the top surface 21. The air inlet pipe 23 is provided with an air inlet channel 231. The air inlet channel 231 passes through the top surface 21. The air distributor 2 is connected to the air outlet end of the mixing chamber 11, and the air inlet pipe 23 extends into the mixing chamber 11.

[0033] The fire cover 3 is disposed on the upper annular wall 22 , and the space between the fire cover 3 and the top surface 21 forms an air intake cavity.

[0034] During installation, the burner 1, gas distributor 2, and fire cover 3 are installed sequentially from bottom to top. The burner 1 is the core component of the gas stove. Its gas inlet connector 12 is sealed and connected to the gas pipeline to enable gas introduction and direct the gas into the gas mixing chamber 11. The gas distributor 2 is then installed on the burner 1. The gas inlet pipe 23 of the gas distributor 2 extends into the gas mixing chamber 11, so that the gas inlet channel 231 is connected to the gas mixing chamber 11, and the gas entering the gas mixing chamber 11 can be directed into the gas inlet channel 231. Finally, the fire cover 3 is placed on the upper annular wall 22 of the gas distributor 2, completing the installation. The space between the fire cover 3 and the top surface 21 of the gas distributor 2 forms the gas inlet chamber to accommodate the gas introduced into the gas inlet channel 231.

[0035] When the gas circulates and burns, the fuel gas enters the mixing chamber 11 from the gas inlet joint 12, and is fully mixed with the air in the mixing chamber 11 to form a combustible mixed gas; the mixed gas enters the gas inlet chamber of the gas distributor 2 through the gas inlet channel 231, and the mixed gas that enters the gas inlet chamber upward is blocked and guided by the fire cover 3, and is dispersed to the surroundings, and is simultaneously discharged outward from a number of gas outlet grooves 221. After being discharged, the gas is ignited to achieve combustion.

[0036] As a specific solution of an embodiment of the present utility model, the upper ring wall 22 has an annular structure and is installed on the upper surface end of the top surface 21 of the gas separator 2; the air inlet pipe 23 extends vertically and is arranged coaxially with the gas separator 2, its upper end is fixedly connected to the lower surface of the top surface 21, and its lower end extends downward into the gas mixing chamber 11 to realize the transmission of the mixed gas.

[0037] A number of air outlet grooves 221 are circumferentially spaced apart on the upper ring wall 22, and each air outlet groove 221 passes through the upper ring wall 22 transversely, forming a two-way opening structure facing inward and outward, so as to form a circumferential outlet function for the mixed gas entering the air inlet cavity and guided by the fire cover 3, thereby forming a fire distribution function on all sides.

[0038] The fire cover 3 is mounted on the upper ring wall 22. During long-term use, when the air outlet grooves 221 are blocked by debris and difficult to clean, the fire cover 3 can be removed in the present application to expose the air outlet grooves 221 for easy cleaning, thereby solving the technical problem in the prior art that the air outlet grooves 221 are blocked by debris and difficult to clean.

[0039] On the basis of the above embodiments, each air outlet groove 221 has an upper opening structure, so that when the fire cover 3 is removed and the debris in the air outlet groove 221 is cleaned, the debris can be quickly pushed outward from the upper opening of the air outlet groove 221 to the air inlet cavity, which is convenient for quick cleaning.

[0040] See also Figure 1 and Figure 2 In the burner of the present invention, each gas outlet groove 221 includes a deep groove 2211 and a shallow groove 2212 , and a shallow groove 2212 is provided between every two deep grooves 2211 .

[0041] In the embodiment of the present invention, the depth of the deep groove 2211 is greater than the depth of the shallow groove 2212. The deep grooves 2211 and the shallow grooves 2212 are arranged in sequence and spaced apart to ensure that the mixed gas entering the air inlet chamber is evenly guided outward by the fire cover 3 and, after being ignited, forms a uniform flame on the outer side of the upper ring wall 22. When the gas is ignited, the flame of the gas guided out of the deep groove 2211 is relatively large, while the flame of the gas guided out of the shallow groove 2212 is relatively small, thereby improving combustion efficiency.

[0042] See also Figures 3 to 5 In the burner of the present invention, a plurality of ribs 24 are evenly distributed along the circumference of the air inlet pipe 23 , and a step surface 241 is provided on the outer edge of the rib 24 , which is supported on the upper edge of the mixing chamber 11 .

[0043] In the embodiment of the present invention, the air distributor seat 2 has a lower opening structure, one end of the rib plate 24 is fixedly connected to the side wall of the air intake pipe 23, and the other end is fixedly connected outward to the inner wall of the air distributor seat 2, so as to support the air intake pipe 23 through the rib plate 24.

[0044] When the gas distributor seat 2 is placed downward on the burner head 1, the step surface 241 abuts against the upper edge of the gas mixing chamber 11. Specifically, the step surface 241 is a multi-step structure with multiple "L"-shaped angles. It abuts downward against the upper side of the gas mixing chamber 11 to be axially supported by the gas mixing chamber 11. At the same time, it abuts outward against the inner side of the gas mixing chamber 11 to form a radial limit for the gas distributor seat 2 through the gas mixing chamber 11, preventing the gas distributor seat 2 from moving horizontally relative to the burner head 1, thereby ensuring the stable installation of the gas distributor seat 2 and ensuring that the gas distributor seat 2 forms a stable gas distribution effect.

[0045] In the burner of the present invention, the inner wall surface of the gas mixing chamber 11 is provided with a limiting strip 111 corresponding to the rib plate 24 , and the rib plate 24 abuts against the limiting strip 111 .

[0046] The number of ribs 24 is equal to the number of limit bars 111, and the two are arranged in a one-to-one correspondence. As a specific solution for the arrangement of the ribs 24 and limit bars 111 in this embodiment, one end of the rib 24 is fixedly connected to the side wall of the intake pipe 23, and the other end of the side wall abuts the side of its corresponding limit bar 111.

[0047] If the total number of ribs 24 = X + Y, X ≥ 1, Y ≥ 1, then the other end side surfaces of X ribs 24 simultaneously abut against one side of their respective corresponding limit bars 111, and the sides of the X limit bars 111 corresponding to the X ribs 24 are simultaneously arranged in a clockwise direction. In addition, the other end side surfaces of Y ribs 24 simultaneously abut against the other side of their respective corresponding limit bars 111, and the sides of the Y limit bars 111 corresponding to the Y ribs 24 are simultaneously arranged in a counterclockwise direction.

[0048] The cross-section of the limiting strip 111 can be a triangle, a quadrilateral, or other polygonal structures. In the figure, the cross-section of the limiting strip 111 is shown as a triangular structure, that is, as one of the setting schemes, the other end side surfaces of two adjacent ribs 24 respectively abut against the two facing side surfaces, or the two opposite side surfaces, of the two adjacent limiting strips 111. Thus, the multiple limiting strips 111 form a limit for the multiple ribs 24, and then form a limit for the air inlet pipe 23 and the gas distributor 2, preventing the gas distributor 2 from rotating relative to the burner head 1, and achieving stable installation of the gas distributor 2.

[0049] See also Figure 1 and Figure 2 In the burner of the present invention, at least two first support platforms 211 are provided on the top surface 21 , and the first support platforms 211 are spaced apart and distributed on the same circular ring, and the fire cover 3 is supported by the first support platforms 211 at the same time.

[0050] As a specific solution of this embodiment, the number of first support platforms 211 can be two, three, four, five, etc., and the first support platforms 211 are evenly spaced along the central axis of the gas distributor 2, and the height of each first support platform 211 is higher than the height of the upper ring wall 22, so as to achieve stable support for the fire cover 3 through each first support platform 211.

[0051] A reinforcing rib 212 extends from the outer annular wall surface of each first support platform 211 toward the inner wall surface of the upper annular wall 22 . The height of the reinforcing rib 212 is lower than that of the first support platform 211 .

[0052] Each reinforcing rib 212 connects its corresponding first support platform 211 and the inner sidewall of the upper annular wall 22 to enhance the structural strength of the first support platform 211, prevent deformation of the first support platform 211 due to heat, and ensure that each first support platform 211 provides stable support for the fire cover 3. The height of the reinforcing rib 212 is lower than that of the first support platform 211, ensuring that each first support platform 211 provides independent and stable support for the fire cover 3. Furthermore, the reinforcing rib 212 fills the structural gap between the first support platform 211 and the inner sidewall of the upper annular wall 22, reducing blind spots for cleaning. This helps users more easily clean the internal components of the gas stove and maintain its good hygiene.

[0053] See also Figure 1 and Figure 2 The burner of the present invention is further provided with a second support platform 213 on the top surface 21. The second support platform 213 and each first support platform 211 are located on the same circular ring. The height of the second support platform 213 is adapted to the height of the first support platform 211, and the arc length of the second support platform 213 is greater than the arc length of the first support platform 211.

[0054] The second support platform 213 located on the same circular ring as each first support platform 211 supports the fire cover 3 together with each first support platform 211, making the fire cover 3 more stable. Specifically, due to the addition of the second support platform 213, the weight of the fire cover 3, which was originally borne only by the first support platform 211, can now be shared by the second support platform 213 and the first support platform 211, which helps to reduce the pressure on each support point and improve the overall support stability; at the same time, the arc length of the second support platform 213 is greater than that of the first support platform 211, which means that on the same circular ring, the second support platform 213 provides a longer support surface, which helps to better resist deformation when subjected to external forces (such as thermal expansion) and maintain the stability of the fire cover 3 and the entire combustion system.

[0055] In the burner of the present invention, extension walls 214 extend from the inner wall of the upward annular wall 22 on both sides of the second support platform 213. The two extension walls 214 and the second support platform 213 form an ignition space a. The portion of the top surface 21 corresponding to the ignition space a is provided with a through hole 215 for installing an ignition needle, and the upper edge of the second support platform 213 is provided with an ignition groove 2131.

[0056] In this embodiment, the ignition groove 2131 extends transversely through both sides of the second support platform 213 to connect the ignition space a with the air intake chamber. Furthermore, the ignition groove 2131 is located at the upper edge of the second support platform 213, forming an upper opening. This facilitates the removal of the fire cover 3 and the quick removal of debris from the air outlet groove 221 by quickly pushing debris outward from the upper opening of the ignition groove 2131 and away from the air intake chamber, achieving rapid cleaning.

[0057] During combustion, the mixed gas entering the air intake chamber is blocked and guided by the fire cover 3, dispersing in all directions and being simultaneously discharged outward through the plurality of gas outlet slots 221. During this process, the fire cover 3 blocks and guides the mixed gas, which in turn is discharged from the ignition slot 2131 into the ignition space a. When the ignition needle in the through hole 215 ignites, the gas discharged into the ignition space a is ignited. Simultaneously, the gas discharged outward from the plurality of gas outlet slots 221 is also ignited, forming a ring-shaped flame around the gas distributor 2.

[0058] The ignition needle is installed in the through hole 215, which can prevent the gas discharged from the gas outlet groove 221 from being directly ignited during the ignition operation through the ignition needle, and indirectly ignite the gas in the ignition space a, thereby improving fire safety.

[0059] The ignition needle is installed in the through hole 215, and the upper edges of the two extension walls 214 and the upper edge of the second support platform 213 are located on the same plane, so that the upper edges of the two extension walls 214 are in contact with the fire cover 3, forming a partition between the ignition space a and the air intake chamber, so that the gas in the air intake chamber can only be ignited after being discharged from the ignition groove 2131, thereby improving the safety of fire use and reducing the uncertainty of gas being ignited arbitrarily. In addition, the upper edges of the two extended walls 214 abut against the fire cover 3 to support the fire cover 3, which can relatively improve the stability of the fire cover 3 when supported; at the same time, the two extended walls 214 connect the second support platform 213 and the inner wall of the upper ring wall 22 to improve the structural strength of the second support platform 213, prevent the second support platform 213 from being deformed due to heat, and ensure the stable support effect of the second support platform 213 on the fire cover 3; in addition, the structural gap between the second support platform 213 and the inner wall of the upper ring wall 22 is filled by the two extended walls 214, reducing cleaning dead corners, which helps users to clean the internal components of the gas stove more conveniently and maintain it in good sanitary condition.

[0060] Please refer to Figures 2 to 4 In the burner of the present invention, the lower surface of the top surface 21 corresponding to the ignition space a extends downward to form a sinking platform 216, and the part of the burner head 1 located outside the gas mixing chamber 11 extends upward with a support platform 13. When the gas distributor seat 2 is connected to the burner head 1, the sinking platform 216 is supported by the support platform 13.

[0061] On the basis of the above embodiment, a through hole 215 is vertically penetrated and opened in the sink 216, and the ignition needle is located in the through hole 215 of the sink 216, so that the sink 216 provides a more stable and reliable ignition environment for the ignition of the ignition needle, which helps to ensure the stability and uniformity of the flame during ignition, thereby improving the ignition success rate and combustion efficiency.

[0062] The setting of the sinker 216 improves the structural strength of the gas distributor 2; and when the gas distributor 2 is connected to the burner head 1, the sinker 216 is supported by the support platform 13, so that the stability of the gas distributor 2 supported on the burner head 1 is improved. Due to the mutual cooperation between the sinker 216 and the support platform 13, the vibration and displacement caused by gas combustion during use can be effectively reduced, thereby extending the service life of the equipment and maintaining its good working condition.

[0063] Please refer to Figure 1 、 Figure 2 as well as Figure 5 In the burner of the present invention, a connecting platform 14 is provided on the burner head 1, and a first mounting hole 141 and a second mounting hole 142 are provided on the connecting platform 14. The first mounting hole 141 is used to install a thermocouple, and the second mounting hole 142 is used to install an ignition needle. The second mounting hole 142 is arranged corresponding to the through hole 215.

[0064] During use, the thermocouple is installed in the first mounting hole 141 and the ignition needle is installed in the second mounting hole 142. The ignition needle is arranged correspondingly to the through hole 215, ensuring that the ignition needle can accurately ignite the gas. In this embodiment of the utility model, the thermocouple, as a key component of the flameout protection device, is installed in the first mounting hole 141 to effectively monitor the combustion status of the burner. Once the flame is extinguished, the thermocouple will quickly respond and cut off the gas supply, thereby preventing gas leaks and safety accidents, and improving the safety of the gas burner.

[0065] In this embodiment, the connecting platform 14 is installed on the outside of the burner 1, so that the installed thermocouple and ignition needle are located on the outside of the burner 1, which facilitates the rapid installation, removal and replacement of the thermocouple and ignition needle.

[0066] On the basis of the above embodiment, two openings are provided on the side wall of the connecting platform 14, and the two openings are connected to the first mounting hole 141 and the second mounting hole 142 respectively. The connecting platform 14 can be made of elastic rubber material so as to facilitate clamping and installing the thermocouple and the ignition needle in the first mounting hole 141 and the second mounting hole 142 respectively, so that the thermocouple and the ignition needle can be stably and quickly installed.

[0067] The above are only preferred embodiments of the present invention and are not intended to limit the present invention. Any modifications, equivalent replacements or improvements made within the spirit and principles of the present invention should be included in the scope of protection of the present invention.
