Description

Technical Field

[0001] This application belongs to the field of combustion device technology, and in particular relates to a gas burner head and a gas stove. Background Technology

[0002] A combustion device is a kitchen appliance that uses gaseous fuels such as liquefied petroleum gas (liquid), manufactured gas, and natural gas for direct-fire heating. Direct-fire is produced by introducing gaseous fuel into a gas stove, mixing it with air, and then igniting the mixture.

[0003] In related technologies, in order to achieve better combustion performance, the combustion device is equipped with multiple ejector channels, each with its own gas supply. The mixing chamber in the combustion device is also divided into multiple areas, each connected to one of the ejector channels. However, setting multiple areas in the mixing chamber results in smaller spaces in each area, which makes it difficult to disassemble and install the components in the mixing chamber. Summary of the Invention

[0004] This application aims to at least partially solve the technical problem of the small space in various areas of the mixing chamber in current gas stoves, which makes it difficult to install and disassemble the components in the mixing chamber. To this end, this application provides a gas burner and a gas stove.

[0005] This application provides a gas burner head, including a burner head body. The burner head body has a mixing chamber, a first ejector chamber, a second ejector chamber, and a gas supply chamber. The burner head body has a gas inlet, a first air inlet, and a second air inlet communicating with the mixing chamber.

[0006] The mixing chamber is provided with a removable partition to divide the mixing chamber into a first mixing section and a second mixing section. The first mixing section is connected to the air supply chamber through the first ejector chamber, and the second mixing section is connected to the air supply chamber through the second ejector chamber.

[0007] In the gas burner head disclosed in this application, a baffle divides the mixing chamber into two areas, which are respectively connected to the first ejector chamber and the second ejector chamber, preventing the mixed gas entering the first ejector chamber from interfering with each other. The baffle is detachably disposed in the mixing chamber. When it is necessary to disassemble or install components in the mixing chamber, such as nozzles, the space inside the mixing chamber can be increased by disassembling the baffle, which facilitates the installation and disassembly of components.

[0008] In some embodiments, the inner wall of the mixing chamber is provided with a mounting groove that mates with the partition. The mounting groove has a first end and a second end opposite to each other. The first end is provided with a slot. The width of the portion of the mounting groove adjacent to the first end is greater than the width of the portion of the mounting groove adjacent to the second end.

[0009] The installation slot facilitates the fixing of the partition in the mixing chamber, and the upper-wide and lower-narrow structure of the installation slot ensures a stable and reliable fixing effect for the partition.

[0010] In some embodiments, the burner body is further provided with a flow guiding cavity, the gas mixing cavity and the flow guiding cavity are respectively located on both sides of the gas supply cavity, and the flow guiding cavity is connected to the gas supply cavity. The two ends of the first ejector cavity are respectively connected to the gas mixing cavity and the flow guiding cavity. The first ejector cavity and the flow guiding cavity are connected by a curved transition, and the flow guiding cavity and the gas supply cavity are connected by a curved transition.

[0011] By setting the mixing chamber and the guide chamber on both sides of the supply chamber, a certain distance is created between the mixing chamber and the guide chamber. The first ejector chamber is connected between the mixing chamber and the supply chamber, so that the mixed gas in the mixing chamber needs to pass through the first ejector chamber and the guide chamber to enter the supply chamber. This increases the distance the gas travels to the supply chamber, allowing the mixed gas to be fully mixed during the movement.

[0012] The curved transition connection between the first ejector cavity and the guide cavity, and the curved transition connection between the guide cavity and the gas supply cavity, allows the gas mixture to enter the guide cavity and the gas supply cavity after it reaches the connection between the first ejector cavity and the guide cavity, and the connection between the guide cavity and the gas supply cavity. This prevents the gas mixture from accumulating at the connection, thus ensuring smooth gas flow between the gas mixture cavity and the gas supply cavity.

[0013] In some embodiments, the first ejector cavity has a third end connected to the guide cavity and a fourth end connected to the mixing cavity, wherein the end of the guide cavity connected to the gas supply cavity is bent toward the fourth end.

[0014] This allows the gas supply chamber connected to the guide chamber to be relatively close to the mixing chamber, resulting in a relatively short overall structure formed by the connection of the first ejector chamber, the guide chamber, and the gas supply chamber. Consequently, the length of the burner body does not need to be too long, making it easier to install and place the gas burner.

[0015] In some embodiments, the air supply chamber is disposed against the outer wall of the first ejector chamber.

[0016] This allows for a gapless connection between the gas supply chamber and the first ejector chamber, resulting in a more compact internal structure for the burner head.

[0017] In some embodiments, the burner body is further provided with a second ejector cavity. The gas supply cavity includes a first cavity and a second cavity. The first cavity is arranged around the second cavity. The first cavity is connected to the flow guide cavity. One end of the second ejector cavity is connected to the gas mixing cavity. The other end of the second ejector cavity is connected to the second cavity.

[0018] The second ejector cavity can supply gas to the second cavity independently, preventing the mixed gas in the first ejector cavity from interfering with the mixed gas in the second ejector cavity.

[0019] In some embodiments, the extension direction of the second ejector cavity is offset from the center of the second cavity.

[0020] This increases the length of the second ejector cavity, allowing the mixed gas to mix more thoroughly within the first ejector cavity.

[0021] In some embodiments, the extension direction of the second ejector cavity is tangent to the edge of the second cavity, and the second ejector cavity and the second cavity are also connected by a curved transition.

[0022] The second ejector cavity is tangent to the edge of the second cavity, which maximizes the length of the second ejector cavity.

[0023] In some embodiments, the second ejector cavity has a fifth end connected to the second cavity portion and a sixth end connected to the mixing cavity, the fifth end being bent toward the sixth end.

[0024] This allows the second cavity connected to the fifth end to be relatively close to the mixing chamber, thereby making the overall structural length of the connection between the second ejector cavity and the second cavity shorter, which in turn reduces the length of the burner body, ultimately making the gas burner easier to install and place.

[0025] In some embodiments, the burner body is further provided with a second air inlet communicating with the mixing chamber. The second air inlet is provided with a removable sealing plate so that the second air inlet can be opened and closed.

[0026] The openable and closable second air inlet allows the gas burner to operate in either an upward air intake mode or a simultaneous upward and downward air intake mode.

[0027] This application also proposes a gas stove, including the aforementioned gas burner head.

[0028] In some embodiments, the gas stove further includes a gas distribution plate disposed on the burner body and opposite to the gas supply chamber. The burner body is provided with a first connector, and the gas distribution plate has a second connector. The first connector and the second connector cooperate to limit the radial displacement of the gas distribution plate.

[0029] The first and second connectors work together to keep the air distribution plate stable. Attached Figure Description

[0050] This application is described below with reference to the accompanying drawings and specific embodiments:

[0051] Example 1

[0052] Please refer to Figures 1-11 This application discloses a gas burner head that can be applied to a gas stove. A gas stove is a device that burns gaseous fuel, which can mix gaseous fuel with air to form a mixed gas, ignite the mixed gas through an ignition device to produce a flame, and maintain the flame for a long time by continuously supplying the mixed gas.

[0053] The gas burner head in this embodiment includes a burner head body 100, which is the basic component of the gas burner head and provides an installation base for at least some other components of the gas burner head. Since the gas stove generates a high-temperature flame during operation, the burner head body 100 can be made of a high-temperature resistant metal material, specifically a copper alloy, to prevent deformation during operation. Alternatively, it can be made of a high-temperature resistant ceramic material. This application does not limit the specific material of the burner head body 100.

[0054] The burner head body 100 has a mixing chamber 110, a guiding chamber 130, a gas supply chamber 140, and a first ejector chamber 120, all of which are located inside the burner head body 100. Specifically, the burner head body 100 can be a one-piece structure, and the mixing chamber 110, guiding chamber 130, gas supply chamber 140, and first ejector chamber 120 can be formed within the burner head body 100 by casting. This gives the burner head body 100 better structural strength, thereby improving its reliability and durability. It also reduces the manufacturing difficulty of the burner head body 100, which is beneficial for mass production.

[0055] The burner head body 100 has a gas inlet 111 and a first air inlet 112. The gas inlet 111 can be connected to a gas pipeline, allowing gaseous fuel to enter the burner head body 100 through the gas inlet 111. The first air inlet 112 is an opening on the surface of the burner head body 100, allowing external air to enter the burner head body 100 through the first air inlet 112. Both the gas inlet 111 and the first air inlet 112 are connected to the mixing chamber 110, so that both gaseous fuel and air can enter the mixing chamber 110, allowing the gaseous fuel and air to begin mixing.

[0056] After the gaseous fuel and air are mixed, they enter the gas supply chamber 140. An ignition device can be installed inside or near the gas supply chamber 140 to ignite the gas mixture and produce a flame. A guide chamber 130 and a mixing chamber 110 are located on opposite sides of the gas supply chamber 140 and are connected by a first ejector chamber 120. The gas supply chamber 140 separates the guide chamber 130 and the mixing chamber 110, creating a certain distance between them. Therefore, the gas mixture in the mixing chamber 110 needs to pass through the first ejector chamber 120 and the guide chamber 130 to reach the gas supply chamber 140, increasing the distance traveled and ensuring thorough mixing.

[0057] Once the gaseous fuel and air are fully mixed and reach the gas supply chamber 140, the ignition device can ignite the well-mixed gas mixture, allowing for more complete combustion and resulting in a stronger flame. Simultaneously, since the gas mixture in the mixing chamber 110 must pass through the first ejector chamber 120 and the guide chamber 130 into the gas supply chamber 140, the gas mixture reaching the gas supply chamber 140 is thoroughly mixed, thus maintaining a stable flame intensity after ignition.

[0058] The aforementioned guide cavity 130 can be configured to be bent relative to the first ejector cavity 120. In this way, after the mixed gas reaches the end of the first ejector cavity 120, the inner wall of the end of the first ejector cavity 120 has the function of blocking the mixed gas, which slows down the flow rate of the mixed gas. At the same time, the mixed gas needs to turn and enter the guide cavity 130, which makes the time required for the mixed gas to pass through the first ejector cavity 120 longer, so that the mixed gas can be mixed more thoroughly.

[0059] The aforementioned gas supply chamber 140 can be configured to be bent relative to the guide chamber 130. In this way, after the mixed gas enters the guide chamber 130 and moves to the connection between the guide chamber 130 and the gas supply chamber 140, it will be blocked by the inner wall of the guide chamber 130, thereby slowing down the flow rate of the mixed gas. At the same time, the mixed gas needs to turn and enter the gas supply chamber 140, which allows the mixed gas to pass through the guide chamber 130 for a longer time, thereby making the mixed gas more thoroughly mixed.

[0060] The mixed gas needs to change direction multiple times as it passes through the first ejector cavity 120 and the guide cavity 130, ensuring thorough mixing. Multiple first ejector cavities 120 and guide cavities 130 can be provided, with adjacent cavities bent towards each other. This further increases the travel distance of the mixed gas, resulting in more complete mixing of the gaseous fuel and air. Simultaneously, the bent arrangement of the first ejector cavity 120, guide cavity 130, and gas supply cavity 140 increases the length of the gas path between the mixing cavity 110 and the gas supply cavity 140 while maintaining a constant distance between them. Consequently, the size of the burner body 100 does not need to be excessively large, resulting in a smaller space occupied by the burner body 100.

[0061] Because the first ejector cavity 120 and the guide cavity 130 are bent towards each other, and the guide cavity 130 and the air supply cavity 140 are bent towards each other, when the mixed gas passes through to the connection between the first ejector cavity 120 and the guide cavity 130, and the connection between the guide cavity 130 and the air supply cavity 140, the inner walls of the first ejector cavity 120 and the guide cavity 130 will block the airflow of the mixed gas. Although this can prolong the residence time of the mixed gas in the first ejector cavity 120 and the guide cavity 130, it may also cause the mixed gas to stagnate and accumulate at the connection, thereby causing the air passage between the mixing cavity 110 and the air supply cavity 140 to be obstructed.

[0062] Therefore, the first ejector cavity 120 and the guide cavity 130 can be connected by a curved transition, which can guide the mixed gas. Specifically, the guide cavity 130 is bent relative to the first ejector cavity 120. When the mixed gas reaches the connection between the guide cavity 130 and the first ejector cavity 120, the curved transition can guide the mixed gas through the connection, allowing the mixed gas to smoothly enter the guide cavity 130. This prevents the mixed gas from being blocked by the inner wall of the first ejector cavity 120 and accumulating in the first ejector cavity 120, thus ensuring the smooth flow of gas between the first ejector cavity 120 and the guide cavity 130.

[0063] Specifically, the inner wall of the first ejector cavity 120 adjacent to the guide cavity 130 is bent towards the guide cavity 130. When the mixed gas reaches the part of the first ejector cavity 120 adjacent to the guide cavity 130, the mixed gas can move along the bent inner wall of the first ejector cavity 120 under the influence of the wall effect. The bent inner wall can guide the mixed gas, thus preventing the airflow formed by the mixed gas from directly impacting the inner wall of the first ejector cavity 120 and being blocked. This allows the mixed gas to pass smoothly through the connection between the first ejector cavity 120 and the guide cavity 130.

[0064] Meanwhile, the flow guide cavity 130 and the air supply cavity 140 can also be connected by a bending transition. Specifically, the air supply cavity 140 is bent relative to the flow guide cavity 130. When the mixed gas reaches the connection between the flow guide cavity 130 and the air supply cavity 140, the bending transition can guide the mixed gas through the connection, so that the mixed gas can smoothly enter the air supply cavity 140. This prevents the mixed gas from being blocked by the inner wall of the flow guide cavity 130 and accumulating in the flow guide cavity 130, thereby ensuring that the air passage between the flow guide cavity 130 and the air supply cavity 140 is unobstructed.

[0065] Specifically, the inner wall of the guide cavity 130 adjacent to the air supply cavity 140 is curved towards the air supply cavity 140. When the mixed gas reaches the part of the guide cavity 130 adjacent to the air supply cavity 140, the mixed gas can move along the curved inner wall of the guide cavity 130 under the influence of the wall adhesion effect. This can prevent the airflow formed by the mixed gas from directly impacting the inner wall of the guide cavity 130 and being blocked, so that the mixed gas can pass smoothly through the connection between the guide cavity 130 and the air supply cavity 140.

[0066] By setting a curved transition at the connection between the first ejector cavity 120 and the guide cavity 130, and at the connection between the guide cavity 130 and the gas supply cavity 140, the gas path between the mixing cavity 110 and the gas supply cavity 140 is unobstructed, so that the mixed gas can continuously and stably reach the gas supply cavity 140, and ultimately the flame generated by the ignition device igniting the mixed gas in the gas supply cavity 140 is stable.

[0067] In the gas burner head disclosed in this application embodiment, by setting the mixing chamber 110 and the guide chamber 130 on both sides of the gas supply chamber 140, a certain distance is formed between the mixing chamber 110 and the guide chamber 130. The first ejector chamber 120 is connected between the mixing chamber 110 and the gas supply chamber 140, so that the mixed gas in the mixing chamber 110 needs to pass through the first ejector chamber 120 and the guide chamber 130 to enter the gas supply chamber 140, thereby increasing the travel distance of the gas to reach the gas supply chamber 140, so that the mixed gas is fully mixed during the movement.

[0068] The curved transition connection between the first ejector cavity 120 and the guide cavity 130, and the curved transition connection between the guide cavity 130 and the air supply cavity 140, allows the gas mixture to be guided into the guide cavity 130 and the air supply cavity 140 after reaching the connection between the first ejector cavity 120 and the guide cavity 130, and the connection between the guide cavity 130 and the air supply cavity 140. This prevents the gas mixture from accumulating at the connection points, thus ensuring unobstructed airflow between the gas mixing cavity 110 and the air supply cavity 140.

[0069] In some embodiments, the first ejector cavity 120 and the guide cavity 130 can be connected by a bend. Specifically, the inner wall of the first ejector cavity 120 near the guide cavity 130 can be configured as an inclined surface sloping towards the guide cavity 130. This inclined surface can also guide the mixed gas, allowing it to move along the inclined surface into the guide cavity 130. Correspondingly, the guide cavity 130 and the gas supply cavity 140 can also be connected by a bend, which can also guide the mixed gas located at the connection between the guide cavity 130 and the gas supply cavity 140 into the gas supply cavity 140.

[0070] Of course, the aforementioned inclined surface can also be set as a multi-segment inclined surface, a multi-segment curved surface, or a mixture of multi-segment inclined surface and multi-segment curved surface. All of these can guide the mixed gas and make the gas path between the mixing chamber 110 and the gas supply chamber 140 unobstructed.

[0071] In some embodiments, the first ejector cavity 120 has a third end and a fourth end, wherein the third end is connected to the guide cavity 130 and the fourth end is connected to the mixing cavity 110. The end of the guide cavity 130 connected to the gas supply cavity 140 is bent toward the fourth end of the first ejector cavity 120. This allows the gas supply cavity 140 connected to the guide cavity 130 to be relatively close to the mixing cavity 110, thereby making the overall structure formed by the first ejector cavity 120, the guide cavity 130 and the gas supply cavity 140 relatively short. This also means that the length of the burner body 100 does not need to be too long, and ultimately makes the gas burner easy to install and place.

[0072] Specifically, the portion of the first ejector cavity 120 adjacent to the guide cavity 130 is the first part 121, and the portion of the first ejector cavity 120 away from the guide cavity 130 is the second part 122. The guide cavity 130 is positioned opposite to the first part 121 of the first ejector cavity 120. This means the guide cavity 130 is not positioned along the extension direction of the first ejector cavity 120, resulting in a more compact overall structure after the guide cavity 130 and the first ejector cavity 120 are connected. The gas supply cavity 140 is positioned opposite to the second part 122 of the first ejector cavity 120. Both the guide cavity 130 and the gas supply cavity 140 are located on one side of the first ejector cavity 120, making the structure of the first ejector cavity 120, the guide cavity 130, and the gas supply cavity 140 more compact and occupying less space within the burner body 100. Consequently, the size of the burner body 100 can also be reduced.

[0073] The aforementioned gas supply chamber 140 can also be configured to be attached to the outer wall of the first ejector chamber 120. Specifically, the outer wall of the first ejector chamber 120 is the inner wall of the gas supply chamber 140, and the outer wall of the gas supply chamber 140 is the inner wall of the first ejector chamber 120. This ensures that there is no gap between the first ejector chamber 120 and the gas supply chamber 140, thereby further making the internal structure of the burner body 100 more compact.

[0074] In some embodiments, the gas supply chamber 140 is composed of a first chamber 141 and a second chamber 142. Specifically, the first chamber 141 surrounds the second chamber 142. A mixture of gaseous fuel and air can enter the first chamber 141 and the second chamber 142. An ignition device can ignite the mixture in the first chamber 141 and the mixture in the second chamber 142, thereby generating a central flame above the second chamber 142 and an outer flame surrounding the central flame above the first chamber 141. The central flame and the outer flame act simultaneously on the object to be heated, ensuring uniform heating and resulting in better heating performance of the gas stove using this gas burner.

[0075] Of course, the first cavity 141 and the second cavity 142 described above can also be arranged opposite to each other or cross each other. This application does not limit the specific arrangement of the first cavity 141 and the second cavity 142.

[0076] The first cavity 141 is connected to the guide cavity 130. The mixed gas in the mixing cavity 110 enters the first cavity 141 after passing through the first ejector cavity 120 and the guide cavity 130. The burner body 100 is also provided with a second ejector cavity 150. One end of the second ejector cavity 150 is connected to the mixing cavity 110, and the other end of the second ejector cavity 150 is connected to the second cavity 142. In this way, part of the mixed gas in the mixing cavity 110 can enter the second cavity 142 through the second ejector cavity 150, thereby filling the second cavity 142 with mixed gas. The first ejector cavity 120 and the second ejector cavity 150 inject mixed gas separately into the first cavity 141 and the second cavity 142 respectively. Since the first ejector cavity 120 and the second ejector cavity 150 are independent of each other, the airflow through the first ejector cavity 120 and the airflow through the second ejector cavity 150 are also independent of each other and will not interfere with each other. This allows the amount of mixed gas in the first cavity 141 and the second cavity 142 to remain stable, and ultimately the flame formed above the first cavity 141 and the flame formed above the second cavity 142 remain stable.

[0077] In some embodiments, the second ejector cavity 150 may be configured such that its extension direction is offset from the center of the second cavity 142. Specifically, the axis of the second ejector cavity 150 will not intersect with the center of the second cavity 142. This ensures that the flow direction of the mixed gas discharged from the second ejector cavity 150 will not be directly towards the center of the second cavity 142. After entering the second cavity 142, the mixed gas needs a certain amount of time to diffuse and fill the second cavity 142, so that the mixed gas can be further mixed after reaching the second cavity 142. This allows for more complete contact between the gaseous fuel and air, and ultimately more complete combustion of the mixed gas in the second cavity 142.

[0078] The second cavity 142 can be circular in its height direction, thus forming a near-cylindrical structure. Correspondingly, the inner wall of the second cavity 142 is arc-shaped, guiding the mixed gas. Under the influence of the wall effect, the mixed gas entering the second cavity 142 through the second ejector cavity 150 can travel along the arc-shaped inner wall, ensuring a uniform concentration of the mixed gas in all parts of the second cavity 142. Simultaneously, the extension direction of the second ejector cavity 150 can be tangent to the second cavity 142, placing it at the outermost edge of the second cavity 142, maximizing the distance between the mixed gas entering the second cavity 142 and its center.

[0079] Of course, the cross-section of the second cavity 142 in the height direction can also be set to be rectangular. One end of the second ejector cavity 150 can be connected to the corner of the second cavity 142. This will maximize the distance between the connection between the second ejector cavity 150 and the second cavity 142 and the center of the second cavity 142. This will also achieve the effect that the edges of the second ejector cavity 150 and the second cavity 142 are tangent.

[0080] Of course, in order to make the mixed gas more thoroughly mixed during the process of passing through the second ejector cavity 150, the second ejector cavity 150 can be bent, specifically by adopting a "spiral bend" or a "Z-shaped bend". This can increase the length of the second ejector cavity 150, so that the mixed gas travels a longer distance to reach the second cavity 142. This application does not limit the specific cavity shape of the second ejector cavity 150.

[0081] In some embodiments, the second ejector cavity 150 has a fifth end and a sixth end, wherein the fifth end communicates with the second cavity portion 142 and the sixth end communicates with the mixing cavity 110. The fifth end is bent toward the sixth end, which allows the second cavity portion 142 connected to the fifth end to be relatively close to the mixing cavity 110, thereby making the overall structural length of the connection between the second ejector cavity 150 and the second cavity portion 142 shorter, thus reducing the length of the burner body 100, and ultimately making the gas burner easier to install and place.

[0082] Specifically, the second cavity 142 is located on one side of the extension direction of the second ejector cavity 150, and the projection of the second cavity 142 on the second ejector cavity 150 is located inside the second ejector cavity 150. This makes the overall structure formed by connecting the second cavity 142 and the second ejector cavity 150 more compact, which is beneficial for setting the second ejector cavity 150 and the second cavity 142 in the furnace head body 100.

[0083] In some embodiments, a partition 300 may be provided inside the mixing chamber 110. The partition 300 can divide the mixing chamber 110 into multiple regions. Specifically, the two sides of the partition 300 are a first mixing section 114 and a second mixing section 115, respectively. In this way, the gaseous fuel entering the mixing chamber 110 through the gas inlet 111 is divided into two parts by the partition 300, and the two parts of gaseous fuel are located in the first mixing section 114 and the second mixing section 115, respectively. The air entering the mixing chamber 110 through the first air inlet 112 is also divided into two parts by the partition 300, and the two parts of air enter the first mixing section 114 and the second mixing section 115, respectively. The gaseous fuel and air in the first mixing section 114 are mixed separately, and the gaseous fuel and air in the second mixing section 115 are also mixed separately.

[0084] The first mixing section 114 is connected to the first ejector cavity 120, and the mixed gas in the first mixing section 114 can enter the first cavity 141 through the first ejector cavity 120 and the guide cavity 130. The second mixing section 115 is connected to the second ejector cavity 150, and the mixed gas in the second mixing section 115 can enter the second cavity 142 through the second ejector cavity 150. This prevents the mixed gas entering the first ejector cavity 120 and the mixed gas entering the second ejector cavity 150 from interfering with each other, thereby keeping the flow rate of the mixed gas entering the first cavity 141 and the second cavity 142 stable, and ultimately keeping the flame burning above the first cavity 141 and the flame burning above the second cavity 142 stable.

[0085] The partition 300 is detachably disposed within the mixing chamber 110. Removing the partition 300 from the mixing chamber 110 increases the space within the chamber, facilitating the installation or removal of components. Specifically, a nozzle is provided within the mixing chamber 110, connected to a gaseous fuel pipeline, allowing gaseous fuel to enter the mixing chamber 110. Removing the partition 300 provides the operator with greater usable operating space, facilitating the removal or installation of the nozzle within the mixing chamber 110. Of course, removing the partition 300 also facilitates the installation or removal of other components within the mixing chamber 110.

[0086] To allow the partition 300 to be detachably installed within the mixing chamber 110, a first mounting groove 116 can be formed on the inner wall of the mixing chamber 110. The groove shape of the first mounting groove 116 matches the partition 300, allowing the partition 300 to be inserted into the first mounting groove 116, thereby fixing the partition 300 within the mixing chamber 110. Specifically, when the partition 300 is positioned within the first mounting groove 116, the side of the partition 300 facing away from the first mounting groove 116 can abut against the inner wall of the mixing chamber 110, thus ensuring the stability of the partition 300.

[0087] The first mounting groove 116 has a first end and a second end. The first end has a slot, allowing the partition 300 to be inserted into the first mounting groove 116 through the slot. The second end is located at the bottom of the first mounting groove 116. The width of the portion of the first mounting groove 116 adjacent to the first end is greater than the width of the portion adjacent to the second end, thus the first mounting groove 116 can have a structure that is wider at the top and narrower at the bottom. This facilitates the insertion of the partition 300 into the first mounting groove 116 and ensures that the partition 300 remains stable after being fully inserted into the first mounting groove 116.

[0088] Of course, the partition 300 can also have a structure where one side is relatively thicker and the other side is relatively thinner. This allows the thinner side of the partition 300 to engage with the narrower side of the first mounting groove 116, and the thicker side of the partition 300 to engage with the wider side of the first mounting groove 116. This results in a tighter fit between the partition 300 and the first mounting groove 116. This application does not limit the specific shape of the partition 300.

[0089] The inner wall of the mixing chamber 110 can also be provided with a second mounting groove 117 opposite to the first mounting groove 116. The groove shape of the second mounting groove 117 also matches the shape of the partition 300. In this way, the other side of the partition 300 can be accommodated in the second mounting groove 117, thereby achieving the purpose of fixing both sides of the partition 300. After the partition 300 is installed in the mixing chamber 110, the stability and reliability of the partition 300 are better.

[0090] Of course, in other embodiments, the partition 300 may further include a first side plate 310 and a second side plate 320, which are connected by an elastic connection, making the distance between the first side plate 310 and the second side plate 320 variable. Specifically, in its natural state, there is a certain distance between the first side plate 310 and the second side plate 320. Applying a force to the first side plate 310 and the second side plate 320 can reduce the distance between them, thereby reducing the overall thickness of the partition 300.

[0091] The width of the first mounting groove 116 is set to be less than the thickness of the partition 300 in its natural state. This allows the overall thickness of the partition 300 to be reduced by pressing the first side plate 310 and the second side plate 320. The partition 300 is then inserted into the first mounting groove 116 through the slot at its first end. With the partition 300 completely within the first mounting groove 116, the first side plate 310 and the second side plate 320 are released. The elastic force between them pushes them apart, causing the first side plate 310 and the second side plate 320 to abut against the two side walls of the first mounting groove 116, respectively. The friction between the first side plate 310 and the side wall of the first mounting groove 116, and the friction between the second side plate 320 and the side wall of the first mounting groove 116, ensures the partition 300 remains stable within the first mounting groove 116, preventing it from detaching.

[0092] To further ensure the stability and reliability of the partition 300 within the first mounting groove 116, two opposing blocks can be installed at the opening of the first mounting groove 116. The distance between the two blocks is less than the width of the first mounting groove 116. Furthermore, when the first side plate 310 and the second side plate 320 are under pressure, the thinnest thickness of the partition 300 is less than the distance between the two blocks, allowing the partition 300 to be inserted into the first mounting groove 116. After the partition 300 is fully within the first mounting groove 116, and the first side plate 310 and the second side plate 320 are released, the thickness of the partition 300 is greater than the distance between the two blocks. Thus, the two blocks act as a barrier, further preventing the partition from falling out of the first mounting groove 116.

[0093] To enable the first side plate 310 and the second side plate 320 to be elastically connected, a partition 300 can be formed by folding a sheet of material with good flexibility in half. In this way, the first side plate 310 and the second side plate 320 are positioned opposite each other, connected on the same side and separated on the other side, thus making the first side plate 310 and the second side plate 320 elastic. Specifically, the partition 300 can be made of stainless steel, formed by folding a stainless steel sheet in half.

[0094] Of course, the first side plate 310 and the second side plate 320 can also be connected by an elastic element. Specifically, an elastic element can be provided between the first side plate 310 and the second side plate 320. When an external force is applied to the first side plate 310 and the second side plate 320 and they approach each other, the elastic element will be compressed. When the external force is reduced or no longer applied to the first side plate 310 and the second side plate 320, the restoring deformation force of the elastic element can push the first side plate 310 and the second side plate 320 away from each other.

[0095] In some embodiments, a second air inlet 113 may also be provided on the mixing chamber 110, so that the mixing chamber 110 has multiple air inlets to increase the air flow. Specifically, when a gas stove needs to produce a flame with greater firepower, this can be achieved by increasing the flow rate of gaseous fuel entering the mixing chamber 110, and at the same time, the required air flow also increases.

[0096] The second air inlet 113 can be configured to be openable and closable. Specifically, when the flow rate of gaseous fuel entering the mixing chamber 110 through the gas inlet 111 is small, the second air inlet 113 can be set to a closed state. At this time, external air can only enter the mixing chamber 110 through the first air inlet 112. This allows the amount of air entering the mixing chamber 110 to match the amount of gaseous fuel entering the mixing chamber 110 through the gas inlet 111, thereby ensuring that the concentration of each component of the mixed gas reaches the optimal concentration.

[0097] When the flow rate of gaseous fuel entering the mixing chamber 110 through the gas inlet 111 increases, the second air inlet 113 can be opened to increase the flow rate of air entering the mixing chamber 110, so that the amount of air in the mixing chamber 110 matches the amount of gaseous fuel.

[0098] Specifically, the burner body 100 is equipped with a removable sealing plate 400. When the sealing plate 400 is connected to the burner body 100, it blocks the second air inlet 113, thus closing the second air inlet 113. When the sealing plate 400 is removed from the second air inlet 113, the second air inlet 113 is open. The burner body 100 may have screw holes along the edge of the second air inlet 113, and the sealing plate 400 may have corresponding screw holes on the burner body 100. By aligning these screw holes and screwing in bolts, the sealing plate 400 can be fixed to the burner body 100 to block the second air inlet 113. The bolt connection ensures a tight connection between the sealing plate 400 and the burner body 100. Alternatively, the sealing plate 400 and the burner body 100 can be connected by a snap-fit ​​mechanism, which facilitates disassembly of the sealing plate 400. This application does not impose any restrictions on the specific connection method between the sealing plate 400 and the furnace head body 100.

[0099] Example 2

[0100] Based on the aforementioned gas burner head, this application also proposes a gas stove, including the aforementioned gas burner head.

[0101] The aforementioned gas stove also includes a gas distribution plate 500, which is disposed on the burner body 100 and is positioned opposite to the gas supply chamber 140. Specifically, the gas distribution plate 500 is positioned above the gas supply chamber 140. The function of the gas distribution plate 500 is to draw in secondary air, allowing external air to enter the gas supply chamber 140 through the gas distribution plate 500, thus making the combustion of the gas mixture in the gas supply chamber 140 more complete. A first connecting member 160 may be provided on the burner body 100, and a second connecting member 510 may be provided on the gas distribution plate 500. The first connecting member 160 and the second connecting member 510 cooperate to fix the gas distribution plate 500 on the burner body 100 and restrict the radial displacement of the gas distribution plate 500.

[0102] Specifically, the first connecting member 160 can be a step opened on the burner body 100, and the second connecting member 510 can be a step opened on the gas distribution plate 500. The step on the burner body 100 and the step on the gas distribution plate 500 cooperate with each other, so that the gas distribution plate 500 can be snapped onto the burner body 100, thereby limiting the radial displacement of the gas distribution plate 500 and keeping the gas distribution plate 500 stable.

[0103] Of course, it should be noted that the gas burner disclosed in this embodiment can also be applied to other gas stoves, such as gas stoves that use liquid fuel as raw material.
