[0046] In the existing technology, most gas stoves are equipped with a drip tray. On the one hand, the drip tray with different shapes and textures increases the difficulty of cleaning the stove surface; on the other hand, the addition of a drip tray greatly increases the manufacturing cost of the gas stove.

[0047] To solve this technical problem, this utility model provides a gas stove, specifically, a top-intake gas stove without a liquid tray, such as... Figures 1 to 10 As shown.

[0048] Example 1

[0049] like Figures 1 to 9 As shown in the embodiment of this utility model, a burner is introduced, which includes a burner head 4 and a flame cap seat 2. The burner head 4 is provided with a gas injection structure 43 for injecting gas into the ejector tube of the flame cap seat 2.

[0050] Multiple gas injection structures 43 are provided, and the burner cap 2 is installed on the top of the burner head 4 through multiple gas injection structures 43. A positioning structure 200 is provided between the top of at least one gas injection structure 43 and the bottom of the burner cap 2. By providing a positioning structure 200 between the top of the gas injection structure 43 and the bottom of the burner cap 2, relative movement between the burner cap 2 and the gas injection structure 43 can be avoided during use, ensuring that the gas injection port of the gas injection structure 43 and the air inlet end of the injector tube are always aligned, thus ensuring the stability of primary air injection and improving the working stability of the burner.

[0051] In this embodiment, only the necessary gas injection structure 43 is used to support the burner seat 2, which simplifies the installation structure of the burner seat 2, makes it easier for users to clean the panel 1 below the burner seat 2, and makes the appearance of the burner more regular and beautiful.

[0052] When the user needs to clean panel 1, the burner seat 2 and the burner on it can be removed from the top of the gas injection structure 43. There is no need to set a fixing structure between the burner seat 2 and the burner, which simplifies the structure of the burner and helps to reduce the production cost of the gas stove.

[0053] In this embodiment, the gas injection structure 43 is columnar, the burner seat 2 is disc-shaped, and the positioning structure 200 includes an insertion structure and / or suction structure disposed between the bottom of the burner seat 2 and the top of the gas injection structure 43.

[0054] In some possible embodiments, the insertion structure includes an insertion groove and an insertion protrusion 201 disposed between the top of the gas injection structure 43 and the bottom of the burner cap 2, wherein the insertion groove and the insertion protrusion 201 correspond one-to-one. Specifically, the insertion groove is disposed at the bottom of the burner cap 2 and corresponds one-to-one with the insertion protrusion 201 disposed at the top of the gas injection structure 43, and / or, the insertion protrusion 201 is disposed at the bottom of the burner cap 2 and corresponds one-to-one with the insertion groove disposed at the top of the gas injection structure 43.

[0055] Preferred, such as Figure 8 As shown, in this embodiment, the insertion groove is located on the side of the top of the gas injection structure near the axis of the burner seat, and the insertion protrusion 201 is located at the bottom of the burner seat, corresponding to the insertion groove.

[0056] In this embodiment, the insertion groove includes a groove bottom wall extending in a horizontal direction and a groove side wall disposed on the side of the groove bottom wall away from the axis of the flame cap seat. The groove side wall extends upward at an angle away from the axis of the flame cap seat. The insertion protrusion 201 protrudes downward from the bottom of the flame cap seat and fits against the groove bottom wall and the groove side wall of the insertion groove.

[0057] Preferably, at least three gas injection structures are provided with insertion slots on their tops, and the insertion protrusions 201 at the bottom of the burner seat correspond one-to-one with the insertion slots on the top of the gas injection structures.

[0058] like Figure 7 As shown, in some other possible embodiments, the plug-in structure includes a groove 20 provided at the bottom of the burner seat 2, the groove 20 having the same shape as the top of the gas injection structure 43, and the burner seat 2 being fitted onto the top of the gas injection structure 43 through the groove 20.

[0059] Preferably, the top of the gas injection structure 43 is close to the bottom edge of the burner seat 2, and the top of the gas injection structure 43 extends at least partially to the outer periphery of the burner seat 2 on the side away from the axis of the burner seat 2 and fits against the outer peripheral surface of the burner seat 2. The groove 20 is provided on the bottom surface of the burner seat 2 and / or the outer peripheral surface of the burner seat 2.

[0060] The top surface of the gas injection structure 43 is in contact with at least part of the outer peripheral surface of the burner seat 2, which can further improve the stability of the gas injection structure 43 in supporting the burner seat 2 and prevent the burner seat 2 from shifting relative to the gas injection structure 43 during the use of the gas stove.

[0061] In some preferred embodiments, a chamfer is provided at the corner between the bottom surface and the outer peripheral surface of the burner cap 2, the top surface of the gas injection structure 43 abuts against the bottom surface of the burner cap 2, and the side of the top surface of the gas injection structure 43 away from the axis of the burner cap 2 covers the chamfer at the bottom of the burner cap 2. Preferably, the chamfer at the corner between the bottom surface and the outer peripheral surface of the burner cap 2 is set as a rounded corner, and the side of the top surface of the gas injection structure 43 away from the axis of the burner cap 2 is set as an arc-shaped surface that fits the rounded corner.

[0062] Preferably, the groove 20 is provided at the bottom of the burner cap seat 2 and at the chamfer of the bottom of the burner cap seat 2. When the burner cap seat 2 is installed on the top of the gas injection structure 43, the top of the gas injection structure 43 is fitted into the groove 20, so that the appearance of the burner is complete.

[0063] In some preferred embodiments, a corresponding insertion groove and insertion protrusion 201 are provided between the inner wall of the groove 20 and the top surface of the gas injection structure 43 to further improve the positioning effect of the flame cap seat 2.

[0064] In some specific embodiments, the bottom of the burner cap seat 2 is provided with a groove 20 that matches the shape of the top of the gas injection structure 43. An insertion protrusion 201 is provided on the inner wall of the groove 20. The top of the gas injection structure 43 is provided with an insertion slot corresponding to the insertion protrusion 201. When the burner cap seat 2 is installed on top of the gas injection structure 43, the insertion protrusion 201 at the bottom of the burner cap seat 2 is inserted into the top of the gas injection structure 43, and the groove 20 at the bottom of the burner cap seat 2 is fitted onto the top of the gas injection structure 43. This design enhances the positioning effect of the burner cap seat 2 while also improving the overall integrity of the burner and ensuring an aesthetically pleasing appearance.

[0065] Preferably, the insertion protrusion 201 is disposed on the bottom of the groove 20.

[0066] In some possible embodiments, the suction structure includes a first suction part disposed on the top of the gas injection structure 43, and a second suction part disposed at the bottom of the burner seat 2, corresponding to the first suction part.

[0067] Preferably, the second attraction part is a magnetic block embedded in the bottom of the burner cap 2, and the first attraction part is a ferromagnetic component disposed on the top of the gas injection structure 43. Alternatively, at least a portion of the top of the gas injection structure 43 is made of ferromagnetic material, and this portion constitutes the first attraction part.

[0068] In this embodiment, the insertion structure between the top of the gas injection structure 43 and the bottom of the burner seat 2 is uniquely matched. Specifically, the insertion structure between the top of the gas injection structure 43 and the bottom of the burner seat 2 is a foolproof structure, ensuring that the burner seat 2 is installed on the gas injection structure 43 at a unique angle. This ensures the uniqueness of the burner seat 2's installation position and improves the accuracy of its installation. Through this design, no additional circumferential positioning structure is needed between the burner seat 2 and the burner head 4, thus guaranteeing the accuracy of the burner seat 2's installation.

[0069] In some possible embodiments, the gas injection structure 43 is provided with at least three arranged circumferentially along the burner seat 2, and only the top of a portion of the gas injection structure 43 is provided with a plug-in structure between the top of the burner seat 2 and the bottom of the burner seat 2.

[0070] Preferably, in this embodiment, the number of gas injection structures 43 is set to an odd number, and / or the gas injection structures 43 with the plug-in structure between them and the bottom of the burner seat 2 are arranged circumferentially along the burner seat 2, and their distribution is non-centrally symmetrical.

[0071] In some possible embodiments, the distances between the multiple sets of plug-in structures disposed between the top of different gas injection structures 43 and the bottom of the burner seat 2 and the axis of the burner seat 2 are not exactly equal.

[0072] Preferably, the distance between the top of at least one gas injection structure 43 and the axis of the burner seat 2 is different from the distance between the top of the remaining gas injection structures 43 and the axis of the burner seat 2.

[0073] In some possible embodiments, the central angles between the multiple sets of plug-in structures disposed between the top of different gas injection structures 43 and the bottom of the burner seat 2 are not completely equal. Specifically, the angles formed by the lines connecting the multiple sets of plug-in structures to the axis of the burner seat 2 are not completely equal.

[0074] Preferably, in this embodiment, three gas injection structures 43 are provided, and the three gas injection structures 43 are arranged non-collinearly in the horizontal direction. That is, the projections of the three gas injection structures 43 on the horizontal plane form a triangular structure. The burner seat 2 is detachably installed on the top of the three gas injection structures 43, which can ensure the installation stability of the burner seat 2.

[0075] In this embodiment, at least one of the included angles formed by the projections of the three gas injection structures 43 onto the horizontal plane is not equal to 120°.

[0076] In some preferred embodiments, in the horizontal direction, the three gas injection structures 43 are not simultaneously located within the same semicircular area of ​​the disc-shaped burner seat 2, thereby achieving stable support for the burner seat 2.

[0077] Specifically, the three gas injection structures 43 are distributed at different positions on the burner seat 2. The maximum arc length between any two gas injection structures 43 does not exceed a semicircle. That is, the central angle formed by the lines connecting any two gas injection structures 43 to the center of the burner seat 2 is less than 180 degrees, thus forming a stable triangular support structure. This distribution does not require the gas injection structures 43 to be evenly arranged, but it ensures the stability of the support for the burner seat 2.

[0078] Preferably, the distance from the gas injection structure 43 to the center of the burner seat 2 can be the same or different.

[0079] In this embodiment, the gas injection port of the gas injection structure 43 is located on the side of the gas injection structure 43, corresponding to the air inlet end of the ejector tube at the bottom of the burner cap 2. Preferably, the gas injection port is coaxial with the ejector tube.

[0080] In this embodiment, the number of ejector tubes at the bottom of the burner cap 2 is greater than or equal to the number of gas injection structures 43. Specifically, when the number of ejector tubes is equal to the number of gas injection structures 43, a single gas injection mechanism has only one gas injection port, corresponding to the air inlet end of the ejector tube; when the number of ejector tubes is greater than the number of gas injection structures 43, at least one gas injection structure 43 has multiple gas injection ports corresponding to the multiple ejector tubes respectively. That is, a gas injection structure 43 has at least one gas injection port.

[0081] In some specific embodiments, the bottom of the burner seat 2 is provided with three ejector tubes, and the air inlet ends of the three ejector tubes correspond to the gas injection ports of the three gas injection structures 43 respectively.

[0082] In this embodiment, the burner cap 2 includes an inner ring mixing chamber 21 and an outer ring mixing chamber 22. The ejector tube includes a first ejector tube 23 communicating with the inner ring mixing chamber 21 and a second ejector tube 24 communicating with the outer ring mixing chamber 22. The air inlet ends of the first ejector tube 23 and the second ejector tube 24 are both located close to the outer periphery of the outer ring mixing chamber 22. The gas injection structure 43 corresponding to the air inlet ends of the first ejector tube 23 and the second ejector tube 24 is located directly below the outer ring mixing chamber 22. That is, the gas injection structure 43 supports the burner cap 2 from the bottom of the outer ring mixing chamber 22.

[0083] In this embodiment, two second ejector tubes 24 are provided, located on opposite sides of the outer ring mixing chamber 22. The air inlet ends of the two second ejector tubes 24 face the same direction, while the air inlet end of the first ejector tube 23 faces the opposite direction to the air inlet ends of the second ejector tubes 24; or, the air inlet ends of the two second ejector tubes 24 face the opposite direction. This avoids the air inlet ends of the two second ejector tubes 24 and one first ejector tube 23 being concentrated on the same side of the flame cap base 2, ensuring the stability of the flame cap base 2.

[0084] Preferably, the first ejector tube 23 and the second ejector tube 24 extend tangentially along the inner ring mixing cavity 21 and the outer ring mixing cavity 22, respectively. In this embodiment, "the first ejector tube 23 extends tangentially along the inner ring mixing cavity 21" specifically means that the extension direction of the first ejector tube 23 is consistent with the extension direction of a tangent of the inner ring mixing cavity 21; "the second ejector tube 24 extends tangentially along the outer ring mixing cavity 22" specifically means that the extension direction of the second ejector tube 24 is consistent with the extension direction of a tangent of the outer ring mixing cavity 22.

[0085] Preferably, the first ejector tube 23 and the second ejector tube 24 are parallel to each other.

[0086] like Figure 7 As shown, in this embodiment, the air inlet ends of the two second ejector tubes 24 face opposite directions, and the first ejector tube 23 and the second ejector tube 24 are parallel to each other. The first ejector tube 23 is positioned close to one of the second ejector tubes 24 that faces the same direction.

[0087] Specifically, the air inlet of one second ejector tube 24 faces the first direction, and the air inlet of the other second ejector tube 24 faces the second direction, with the first direction being opposite to the second direction. The air inlet of the first ejector tube 23 faces the first direction, and the first ejector tube 23 is positioned close to the second ejector tube 24 whose air inlet faces the first direction.

[0088] In some specific embodiments, the air outlet end of the second ejector tube 24 extends circumferentially along the outer ring mixing chamber 22, and the bottom of the air outlet end of the second ejector tube 24 gradually rises in the direction away from the air inlet end of the second ejector tube 24, thereby improving the guiding effect on the gas and primary air mixture.

[0089] In this embodiment, by setting the air inlet ends of the two second ejector tubes 24 to face opposite directions, the mixture of gas and primary air can spiral upward in the outer ring mixing chamber 22, improving the smoothness of the gas mixture guidance, ensuring the ejection effect of the primary air, and improving the uniformity of the gas and primary air mixture, thereby improving the combustion effect of the gas.

[0090] By setting the first ejector tube 23 close to a second ejector tube 24 with the same orientation, sufficient space can be provided between the outlet end of the second ejector tube 24 (with its air inlet facing the second direction) and the air inlet end of the first ejector tube 23 to accommodate the gas injection structure 43, thus avoiding interference between the air inlet end of the first ejector tube 23 and the air outlet end of the second ejector tube 24.

[0091] Preferably, in this embodiment, a nozzle 431 is installed at the gas injection port of the gas injection structure 43, and the nozzle 431 is coaxial with the air inlet end of the ejector tube.

[0092] In this embodiment, an inner flame cap 211 and an outer flame cap 221 are respectively attached to the top of the inner ring mixing chamber 21 and the top of the outer ring mixing chamber 22, and the mixture of gas and air is burned on the inner flame cap 211 and the outer flame cap 221.

[0093] In some preferred embodiments, an additional circumferential positioning structure is provided between the burner head 4 and the burner cap 2. This circumferential positioning structure allows the user to accurately determine the correct installation angle of the burner cap 2 without needing to distinguish it based on the insertion structure between the gas injection structure 43 and the bottom of the burner cap 2, thus improving the installation efficiency of the burner cap 2. Furthermore, the additional circumferential positioning structure can further improve the installation stability of the burner cap 2.

[0094] In some possible embodiments, the burner cap seat 2 is further provided with a first positioning part 251, which is sleeved around the combustion control assembly on the burner head 4 along the installation direction of the burner cap seat 2. Specifically, the first positioning part 251 is sleeved in the middle of the combustion control assembly, so that the combustion control assembly can perform its function normally.

[0095] In this embodiment, the structure on the burner head 4 itself is fully utilized to achieve circumferential positioning of the burner cap seat 2. There is no need to add a structure to the burner head 4, which helps to simplify the structure on the gas stove panel 1 for installing the burner cap seat 2 and facilitates daily cleaning.

[0105] In this embodiment, the first positioning part 251 can be formed on the flame cap seat 2, welded on the flame cap seat 2, or connected to the flame cap seat 2 with screws.

[0106] In some preferred embodiments, an ignition needle sleeve 44 is provided on the burner head 4, and the ignition needle 41 is fixed on the burner head 4 through the ignition needle sleeve 44; the ignition needle sleeve 44 is sleeved on the outer periphery of the ignition needle 41, and the first positioning part 251 is sleeved with the ignition needle sleeve 44.

[0107] Specifically, the burner head 4 is provided with a coaxial mounting groove and a plug hole. The mounting groove has an internal thread on its wall, and the plug hole is located on the bottom of the mounting groove.

[0108] The ignition needle 41 includes a main body section with a gradually decreasing diameter and a plug section. The plug section is inserted into a plug hole, and the lower end of the main body section abuts against the bottom of the mounting groove.

[0109] The inner diameter of the ignition needle sleeve 44 is the same as the outer diameter of the main body section of the ignition needle 41, or the inner diameter of the ignition needle sleeve 44 is slightly larger than the outer diameter of the main body section. The outer peripheral wall of the lower end of the ignition needle sleeve 44 is provided with an external thread that matches the internal thread on the groove wall of the mounting groove. The ignition needle sleeve 44 is sleeved on the outer periphery of the main body section, and the lower end of the ignition needle sleeve 44 is screwed into the groove wall of the mounting groove.

[0110] Preferably, in this embodiment, a radial protrusion is provided on the outer peripheral wall of the main body segment, and the lower end of the ignition needle sleeve 44 is pressed against the radial protrusion.

[0111] Preferably, in this embodiment, the bottom of the ignition needle sleeve 44 is provided with a receiving groove, which is fitted over the radial protrusion. The depth of the receiving groove is less than or equal to the distance between the upper end face of the radial protrusion and the lower end face of the main body segment. This ensures the effective fixation of the ignition needle 41.

[0112] Preferably, in this embodiment, the radial protrusion is disposed at the lower end of the main body section, and the depth of the receiving groove is equal to the axial dimension of the radial protrusion.

[0113] In some preferred embodiments, the outer peripheral wall of the inner flame cap 211 is provided with a protective cover 27 extending outward, or the inner peripheral wall of the outer flame cap 221 is provided with a protective cover 27 extending inward, and the protective cover 27 is disposed directly above the ignition needle 41 and spaced apart from the ignition needle 41.

[0114] In some possible embodiments, the burner cover 2 is also provided with a second positioning part 253, and the top of the burner head 4 is provided with a columnar protrusion 26 corresponding to the second positioning part 253, and the second positioning part 253 is sleeved with the columnar protrusion 26.

[0115] Specifically, the second positioning part 253 is a cylindrical part that extends vertically downward from the bottom of the burner cover 2. When the burner cover 2 is installed on the burner head 4, the second positioning part 253 is fitted from top to bottom onto the top of the columnar protrusion 26.

[0116] Preferably, in this embodiment, the second positioning part 253 is formed at the bottom of the outer ring mixing cavity 22 of the flame cap seat 2.

[0117] In some preferred embodiments, the burner head 4 is provided with an ignition needle 41 and a thermocouple 42, and the burner cap seat 2 is provided with a first positioning part 251 that cooperates with the ignition needle 41 and the thermocouple 42; at the same time, the burner head 4 is provided with a columnar protrusion 26, and the burner cap seat 2 is provided with a second positioning part 253 that cooperates with the columnar protrusion 26.

[0118] Example 2

[0119] In this embodiment, the top surface of the gas injection structure 43 is adapted to the bottom shape of the burner cap 2, and is used to fit against the bottom of the burner cap 2. That is, the contact points between the gas injection structure 43 and the burner cap 2 are fitted together.

[0120] The difference between this embodiment and Embodiment 1 is that the top surface of the gas injection structure 43 has a microscopic uneven structure, exhibiting a rough characteristic. This increases the coefficient of friction between the top of the gas injection structure 43 and the bottom of the burner seat 2, improving the support stability of the gas injection structure 43 on the burner seat 2, and preventing relative displacement between the burner seat 2 and the gas injection structure 43 during use.

[0121] In some preferred embodiments, the surface roughness of the top surface of the gas injection structure 43 is greater than or equal to the surface roughness of the bottom surface of the burner seat 2.

[0122] Example 3

[0123] like Figure 1 As shown in the present invention, a gas stove is also provided in this embodiment. The gas stove includes the burner in the above embodiment one or embodiment two, and also includes a panel 1 and a housing 10.

[0124] The panel 1 is installed on the top of the housing 10, forming a cavity between the panel 1 and the housing 10, and the burner head 4 is installed inside the cavity. Specifically, the burner head 4 is installed on the bottom of the housing 10 and is fixedly connected to the housing 10 by connecting structures such as screws, bolts, and clips.

[0125] In this embodiment, the burner head 4 mainly consists of a gas injection structure 43, a gas distribution pipe, and a support. The gas distribution pipe is used to deliver gas from the gas valve to the gas injection structure 43. Both the gas distribution pipe and the gas injection structure 43 are fixed on the support, and the support is fixedly connected to the housing 10.

[0126] A mounting opening 12 is provided on the panel 1. The burner head 4 is installed below the panel 1. The gas injection structure 43 at the top of the burner head 4 extends upward through the mounting opening 12 on the panel 1, with the top of the gas injection structure 43 extending above the panel 1. The burner cap seat 2 is installed on the gas injection structure 43 and is positioned opposite to the panel 1. This helps to reduce the size of the mounting opening 12 on the panel 1 and improves the aesthetics of the panel 1.

[0127] like Figure 4 As shown, in this embodiment, the panel 1 has two mounting ports 12. The gas injection structure 43 corresponding to the air inlet end of the first ejector tube 23 and the gas injection structure 43 corresponding to the air inlet end of the second ejector tube 24 with the air inlet end facing the first direction are arranged in the same mounting port 12, and the gas injection structure 43 corresponding to the air inlet end of the ejector tube with the air inlet end facing the second direction is arranged in another mounting port 12.

[0128] Preferably, in this embodiment, the thermocouple 42 and the ignition needle 41 are disposed in one of the mounting ports 12, and the columnar protrusion 26 is disposed in the other mounting port 12.

[0129] Preferably, the thermocouple 42 and the ignition needle 41 correspond to the mounting port 12 which has a gas injection structure 43 inside, and the columnar protrusion 26 corresponds to the mounting port 12 which has two gas injection structures 43 inside.

[0130] In this embodiment, a decorative cover 11 for covering the mounting port 12 is installed at the mounting port 12. The decorative cover 11 has a first opening 111 that matches the outer peripheral shape of the gas injection structure 43, and a second opening 112 that matches the outer peripheral shape of the mounting part.

[0131] Preferably, in this embodiment, the decorative cover 11 includes a plate portion that covers the mounting opening 12 and is fitted to the panel 1, and a cylindrical portion that extends vertically downward from the center of the plate portion and whose outer periphery is fitted to the inner wall of the mounting opening 12. The first opening 111 and / or the second opening 112 are located in the center of the plate portion.

[0132] In some possible embodiments, the columnar protrusion 26 is also used for positioning the decorative cover 11. Specifically, the lower end of the columnar protrusion 26 passes through the second opening 112 and is detachably connected to the burner head 4. The portion of the columnar protrusion 26 above the decorative cover 11 fits against the top of the decorative cover 11 on the outer periphery of the second opening 112, thereby enabling the decorative cover 11 to be fixed on the panel without the need for additional mounting structures such as screws.

[0133] Preferably, the lower end of the columnar protrusion 26 is threadedly connected to the furnace head.

[0134] Preferably, the upper end of the columnar protrusion 26 is in contact with the bottom of the flame cap seat 2, that is, the columnar protrusion can also support the flame cap seat, further improving the installation stability of the flame cap seat.

[0135] In this embodiment, the pot support 3 of the gas stove is fixedly connected to the burner seat 2. The pot support 3 includes a support ring 31 arranged around the burner seat 2 and a support foot connected to the support ring 31.

[0136] Specifically, the support ring 31 is disposed on the outer periphery of the flame cap base 2. The inner diameter of the support ring 31 is the same as the outer diameter of the flame cap base 2, or the inner diameter of the support ring 31 is slightly larger than the outer diameter of the flame cap base 2. The support ring 31 extends in a direction away from the axis of the flame cap base 2. The inner periphery of the support ring 31 is connected to the outer periphery of the flame cap base 2.

[0137] Preferably, the outer diameter of the support ring 31 is greater than or equal to the maximum distance between the edge of the mounting opening 12 and the axis of the burner seat 2. That is, the projection of the outer edge of the support ring 31 on the panel 1 surrounds the mounting opening 12, so that the whole formed by the pot support 3 and the burner seat 2 can cover the mounting opening 12 on the panel 1, further improving the aesthetics of the gas stove.

[0138] Preferably, the outer diameter of the support ring 31 is greater than or equal to the maximum distance between the edge of the decorative cover 11 and the axis of the flame cap seat 2, so that the decorative cover 11 is not exposed, or only a small part of the decorative cover 11 is exposed from the gap between the inner ring mixing cavity 21 and the outer ring mixing cavity 22, which improves the user's visual experience.

[0139] Preferably, in this embodiment, the support ring 31 extends downward at an angle away from the axis of the burner seat 2, and / or the outer periphery of the support ring 31 extends vertically downward. This further enhances the shielding effect of the support ring 31 on the decorative cover 11, preventing the user from directly observing the decorative cover 11 from the side of the pot support 3. With the above arrangement, the outer edge of the support ring 31 extends to the outer periphery of the decorative cover 11, and the outer edge of the support ring 31 is close to the panel 1. Therefore, the user is prevented from directly observing the decorative cover 11 from the oblique front of the gas stove, improving the user's visual experience. Furthermore, under the support of the burner seat 2 on the pot support 3, the outer edge of the support ring 31 is spaced from the panel 1, allowing primary air drawn in through the injector during gas injection and some secondary air required during gas combustion to enter through the gap between the support ring 31 and the panel 1, ensuring combustion efficiency.

[0140] In some preferred embodiments, along the axis away from the burner cap 2, the support ring 31 has a first extension 312 extending upward at an angle away from the axis of the burner cap 2, and a second extension 313 extending vertically downward from the outer edge of the support ring 31. The first extension 312 facilitates the concentration of heat from the flame towards the bottom of the cookware, improving heat utilization. Simultaneously, the second extension 313 ensures effective concealment of the decorative cover 11, maintaining an aesthetically pleasing appearance.

[0141] In this embodiment, the pot support 3 is coaxial with the fire cover seat 2.

[0142] In some possible embodiments, the support legs are only used to support the cookware and are located at the top of the support ring without extending below the support ring. Alternatively, the lower end of the support legs may extend below the support ring, but the portion of the support legs extending below the support ring is hidden by the support ring. Specifically, during normal use, the user cannot see the portion of the support legs located below the support ring, creating a suspended effect for the cookware support and improving the user's visual experience.

[0143] In some other possible embodiments, the lower end of the support leg is close to the panel 1 of the gas stove.

[0144] The support feet can assist the burner seat 2 in supporting the support ring 31. When the weight of the pot supported on the pot support 3 is large, the support ring 31 will deform, so that the panel 1 can provide support force to the support ring 31 through the support feet, thereby improving the stability of the pot support 3 in supporting the pot.

[0145] Preferably, the bottom of the support leg is in contact with the panel 1 of the gas stove, and when the pot support 3 is not supporting a pot, the support leg does not apply pressure to the panel 1, or there is a gap between the lower end of the support leg and the panel 1 of the gas stove.

[0146] In this embodiment, a first support leg 32 is provided on the support ring 31. The first support leg 32 is located on the top of the support ring 31, and the pot support 3 supports the pot through the first support leg 32.

[0147] In this embodiment, the first support leg 32 is provided with a plurality of legs evenly arranged along the circumference of the support ring 31 to ensure the stability of the cookware. Preferably, there are four first support legs 32, which are evenly arranged along the circumference of the support ring 31.

[0148] In some specific embodiments, the first leg 32 is a plate extending radially along the support ring 31, and its top is provided with a support portion extending in a direction close to the axis of the support ring 31. The top of the support portion is provided as an inclined surface extending downward in a direction close to the axis of the support ring 31.

[0149] In some preferred embodiments, the bottom of the support ring 31 is provided with a second foot 33, and the bottom of the second foot 33 is close to the panel 1 of the gas stove.

[0150] Specifically, when no pot is placed on the pot support 3, or when the pot supported on the pot support 3 is light, the bottom of the second foot 33 will not exert pressure on the panel 1, or even come into contact with the panel 1. This avoids the situation where obvious indentations appear on the panel 1 due to prolonged pressure from the second foot 33. At the same time, the design of the second foot 33 can further prevent the pot supported on the pot support 3 from tipping over, improving the stability of the gas stove.

[0151] Preferably, in this embodiment, there is a gap between the bottom of the second support leg 33 and the panel 1 of the gas stove.

[0152] In this embodiment, the second leg 33 is a plate extending radially along the support ring 31.

[0153] Preferably, in this embodiment, the second leg 33 is provided with a plurality of legs corresponding one-to-one with the first leg 32.

[0154] Preferably, the second leg 33 and the first leg 32 are integral parts formed on the support ring 31, and the first leg 32 and the second support together constitute the leg.

[0155] Preferably, in this embodiment, a U-shaped component 34 is provided at the bottom of the second leg 33. The U-shaped component 34 is made of flexible material and is fixed to the bottom of the second leg 33, covering the bottom of the second leg 33. The bottom of the second leg 33 contacts the panel 1 through the U-shaped component 34, which can prevent the panel 1 from being scratched when the bottom of the second leg 33 contacts the panel 1.

[0156] In this embodiment, the U-shaped component 34 can be made of silicone material or heat-resistant rubber material.

[0157] Preferably, in this embodiment, the bottom of the second support leg 33 is lower than the bottom of the burner seat 2. Therefore, when the user removes the burner seat 2 and the pot support 3 and places them, the second support leg 33 can support the whole composed of the burner seat 2 and the pot support 3, so that the whole composed of the burner seat 2 and the pot support 3 can remain stable. This can prevent the bottom of the burner seat 2 from contacting the support surface used to place the burner seat 2 and the pot support 3, and prevent dirt from entering the ejector tube.

[0158] Example 4

[0159] like Figure 9 and Figure 10 As shown, this embodiment provides an assembly scheme between the pot support 3 and the fire cover seat 2 in the above embodiments one to three.

[0160] The pot support 3 is connected to the outer periphery of the fire cover 2 and is ring-shaped. The pot support 3 is sleeved on the outer periphery of the fire cover 2 and is coaxial with the fire cover 2.

[0161] The outer peripheral wall of the burner seat 2 is provided with a first connecting part 35, and the pot support 3 is provided with a second connecting part 36 corresponding to the first connecting part 35. The relative rotation between the burner seat 2 and the pot support 3 causes the first connecting part 35 to be inserted into the second connecting part 36, realizing the pre-installation positioning between the pot support 3 and the burner seat 2. This facilitates the subsequent further fixing of the pot support 3 and the burner seat 2, and improves the positioning effect between the pot support 3 and the burner seat 2, ensuring the fitting accuracy between the pot support 3 and the burner seat 2. In particular, it can ensure the coaxiality between the pot support 3 and the burner seat 2.

[0162] The second connecting portion 36 is provided with a connecting groove 360, which is located on the side of the second connecting portion 36. The orientation of the connecting groove 360 ​​corresponds to the circumferential direction of the pot support 3, or the connecting groove 360 ​​faces the axis of the pot support 3. The end of the connecting groove 360 ​​communicates with at least one side of the second connecting groove 360. The first connecting portion 35 protrudes radially outward from the outer peripheral wall of the burner cap 2. In the circumferential direction of the pot support 3, the first connecting portion 35 and the connecting groove 360 ​​at least partially overlap.

[0163] In some possible embodiments, the opening of the connecting groove 360 ​​faces the side into which the first connecting portion 35 is screwed, that is, the bottom of the connecting groove 360 ​​extends radially along the pot support 3.

[0164] In some possible embodiments, the opening of the connecting groove 360 ​​faces the axis of the pot support 3, that is, the bottom of the connecting groove 360 ​​extends along the circumference of the pot support 3, or the bottom of the connecting groove 360 ​​extends along the tangential direction of the circumference of the end of the first connecting portion 35.

[0165] In this embodiment, the two ends of the connecting groove 360 ​​can be connected to both sides of the second connecting part 36, that is, the connecting groove 360 ​​passes through the second connecting part 36; or the connecting groove 360 ​​can be connected only to the side of the second connecting part 36 that is screwed into the first connecting part 35. Preferably, the bottom of the connecting groove 360 ​​is L-shaped, including a first wall opposite to the axis of the pot support 3 and a second wall extending radially along the pot support 3. Preferably, the first wall extends circumferentially along the pot support 3.

[0166] In some possible embodiments, the second connecting portion 36 is configured as a column, the extending direction of the second connecting portion 36 is parallel to the axis of the flame cap seat 2, and the connecting groove 360 ​​is disposed on one side of the second connecting portion 36.

[0167] In some other possible embodiments, the second connecting part 36 is a bent plate, which is integrated with the pot support 3 and surrounds each other to form the connecting groove 360.

[0168] Preferably, in this embodiment, the second connecting part 36 includes a first connecting plate 361 and a second connecting plate 362. The first connecting plate 361 extends axially along the pot support 3, and the second connecting plate 362 is disposed at the end of the first connecting plate 361 and extends radially along the pot support 3. A connecting groove 360 ​​is formed between the second connecting plate 362 and the pot support 3.

[0169] In some possible embodiments, the second connecting plate 362 extends from the end of the first connecting plate 361 toward the axis of the pot support 3, and forms a connecting groove 360 ​​with the pot support 3 with the groove opening facing the axis of the pot support 3, wherein the first connecting plate 361 constitutes the bottom of the connecting groove 360.

[0170] In this embodiment, the distance between the axis of the first connecting plate 361 and the axis of the pot support 3 is greater than or equal to the distance between the end of the first connecting part 35 and the axis of the fire cover seat 2.

[0171] In some other possible embodiments, one end of the second connecting plate 362 protrudes outward relative to the first connecting plate 361 along the circumference of the pot support 3, and the second connecting plate 362 protrudes from one end of the first connecting plate 361 to form a connecting groove 360 ​​between the pot support 3 and the pot support 3.

[0172] In this embodiment, the first connecting plate 361 can be set at any position between the inner and outer peripheries of the pot support 3. It is only necessary to ensure that the minimum distance between the edge of the second connecting plate 362 and the axis of the pot support 3 is less than the distance between the end of the first connecting part 35 and the axis of the fire cover seat 2.

[0173] Preferably, in this embodiment, the first connecting plate 361 extends axially from the inner periphery of the pot support 3 along the pot support 3. Specifically, the first connecting plate 361 can be a straight plate tangent to the central opening of the pot support 3, or it can be an arc-shaped plate extending along the central opening of the pot support 3. The width of the second connecting plate 362 is greater than the width of the first connecting plate 361, and it bends and extends away from the axis of the pot support 3. This improves the compactness of the assembly between the pot support 3 and the burner seat 2.

[0174] Specifically, the "width of the second connecting plate 362" is the circumferential extension length of the second connecting plate 362 along the central opening.

[0175] Preferably, in this embodiment, the first connecting plate 361 is an arc-shaped plate extending along the central opening of the pot support 3, and the second connecting plate 362 extends radially along the pot support 3, with the side of the second connecting plate 362 near the axis of the pot support 3 aligned with the edge of the central opening of the pot support 3.

[0176] Preferably, one end of the second connecting plate 362 is flush with one end of the first connecting plate 361, and the other end of the second connecting plate 362 protrudes outward relative to the first connecting plate 361 along the circumference of the pot support 3.

[0177] Preferably, in this embodiment, the second connecting part 36 is provided with a plurality of parts arranged at intervals along the circumference of the pot support 3, and the outer peripheral wall of the pot support 3 is provided with a plurality of first connecting parts 35 corresponding one-to-one with the second connecting part 36. When the pot support 3 is sleeved on the outer periphery of the fire cover 2 and rotates relative to the fire cover 2, each first connecting part 35 is respectively engaged in the connecting groove 360 ​​of the corresponding second connecting part 36.

[0178] In this embodiment, the second connecting part 36 can be disposed at the top of the pot support 3 or at the bottom of the pot support 3.

[0179] Preferably, to improve the aesthetics of the gas stove, the second connecting part 36 is located at the bottom of the pot support 3. In this embodiment, the pot support 3 is fitted onto the outer periphery of the burner cap 2 from the top, so that the second connecting part 36 and the first connecting part 35 on the burner cap 2 are at the same height. Then, the pot support 3 is rotated so that the connecting groove 360 ​​on the second connecting part 36 is fitted onto the first connecting part 35.

[0180] like Figure 9 As shown, in this embodiment, the pot support 3 includes a support ring 31 surrounding the burner seat 2 and a support foot disposed on the support ring 31. The support ring 31 is disposed on the outer periphery of the burner seat 2. The inner diameter of the support ring 31 is the same as the outer diameter of the burner seat 2, or the inner diameter of the support ring 31 is slightly larger than the outer diameter of the burner seat 2. The second connecting part 36 is disposed on the support ring 31 and is offset from the support foot in the circumferential and / or radial directions.

[0181] Preferably, in this embodiment, the support leg is disposed on the support ring 31 and is disposed near the outer periphery of the support ring 31, and the second connecting part 36 is disposed near the inner periphery of the support ring 31 and corresponds to the support leg in the radial direction.

[0182] In some specific embodiments, the support legs are provided with four arranged at intervals along the circumference of the pot support frame 3, and the second connecting part 36 is provided with four corresponding to the support legs.

[0183] Specifically, in this embodiment, the support ring 31 is a plate-shaped part extending away from the axis of the pot support 3. The inner circumference of the support ring 31 has a downwardly bent section 311. A first connecting plate 361 extends downward from the lower end of the bent section 311, and a connecting groove 360 ​​is formed between the second connecting plate 362 and the lower end of the bent section 311. By forming a connecting groove 360 ​​between the second connecting plate 362 and the lower end of the bent section 311, the lower end of the bent section 311 can be used as a guide, allowing the first connecting part 35 to be smoothly inserted into the connecting groove 360, improving the smoothness of installation between the burner cap 2 and the pot support 3. Simultaneously, the bent section 311 also better conceals the first connecting part 35 and the second connecting part 36, preventing direct observation by the user during use and improving the appearance of the gas stove.

[0184] Preferably, in this embodiment, the distance between the second connecting plate 362 and the bent section 311 is equal to the thickness of the first connecting part 35. When the first connecting part 35 is inserted into the connecting groove 360, the top of the first connecting part 35 is in contact with the lower end of the bent section 311, and the bottom of the first connecting part 35 is in contact with the second connecting plate 362. This can further improve the tightness of the fit between the first connecting part 35 and the second connecting part 36, and improve the assembly stability between the pot support 3 and the fire cover seat 2.

[0185] In this embodiment, the first connecting part 35 and the second connecting part 36 can be fixed together by any means such as pins, latches, screws, etc.

[0186] In some possible embodiments, after the first connecting part 35 is inserted into the mounting groove, the end of the second connecting plate 362 is bent upward to close the opening of the mounting groove and limit the first connecting part 35 to the mounting groove.
