Description

Technical Field

[0001] This utility model relates to the field of kitchen appliances technology, specifically to a burner and a stove. Background Technology

[0002] As the usage rate of gas stoves increases, people's requirements for the safety of gas stoves are also increasing. Existing gas stoves are usually equipped with temperature sensors to detect the temperature of the pots and pans, and to determine whether there are situations such as burner dry burning or accidental flameout based on the detected temperature. In such cases, the valve can be shut off immediately to avoid safety hazards.

[0003] Most gas stoves on the market currently use a temperature sensor that contacts the bottom of the cookware to detect its temperature. When the bottom temperature exceeds a preset temperature, the stove automatically shuts off to protect the flame. Simultaneously, if the stove accidentally shuts off or if a pot is left unattended on high heat for an extended period, the valve can be shut off immediately based on the temperature sensor's readings to prevent accidents. However, temperature sensors have certain limitations. For example, because they need to contact the bottom of the cookware, only flat-bottomed pans can be used for cooking to avoid interference. Additionally, the temperature sensor is susceptible to the effects of high-temperature flames, which can cause it to inaccurately detect the bottom temperature of the cookware, leading to abnormal flameouts.

[0004] Some gas stoves place the temperature sensor below the control panel. This non-contact sensor detects temperature simply by receiving infrared radiation from the bottom of the pot. Additionally, to prevent liquids and oil from contaminating the sensor, some gas stoves use a translucent plate between the sensor and the pot, installed within a central hole in the burner cap. While this method avoids frequent contact between the sensor and the bottom of the pot and blocks dripping liquids and oil from affecting the sensor, the translucent plate still requires separate installation of the sensor and the temperature sensor, and oil flowing down from the central hole can still affect the sensor. Utility Model Content

[0005] In order to at least partially solve the problems existing in the prior art, according to one aspect of the present invention, a burner is provided, the technical solution of which is as follows.

[0006] The burner includes an ejector tube, a support, a burner seat, a burner cap, a light-transmitting element, a mounting base, and a temperature measuring element for sensing temperature signals. The ejector tube is positioned by the support. The burner cap and the burner seat enclose a mixing element with a mixing chamber. The mixing element is located above the support. The ejector tube is connected to the mixing chamber. The support has mounting holes. The mounting base passes through the mounting holes. The mounting base has a hollow portion. The temperature measuring element is at least partially located in the hollow portion. The light-transmitting element is located at the top of the mounting base and blocks the temperature measuring element from above. A temperature measuring channel is formed on the mixing element. The mounting base is at least partially located within the projection area of ​​the temperature measuring channel.

[0007] The burner of this utility model has a temperature measuring element and a light-transmitting element connected to a bracket via a fixed base. The temperature measuring element is at least partially located within the hollow portion, and the light-transmitting element is positioned at the top of the fixed base, shielding the temperature measuring element from above. On one hand, the temperature measuring element and the light-transmitting element can be connected to the bracket simultaneously, which not only facilitates installation but also ensures that the temperature measuring element is not in contact with the bottom of the pot when the burner is used on a stove to heat the pot. This prevents the temperature measuring element from being affected by the flame, ensuring the accuracy of temperature detection, and avoids interference between the temperature measuring element and the pot, thereby expanding the types of pots that can be used on the stove and broadening the applicability of the stove. On the other hand, since the temperature measuring element is at least partially located within the hollow portion, and the light-transmitting element shields the temperature measuring element from above, when the temperature measuring element detects the temperature of the bottom of the pot, the light-transmitting element can prevent liquids, oil stains, etc., from dripping vertically onto the temperature measuring element, avoiding any impact on the temperature measuring element and thus ensuring the accuracy of temperature measurement.

[0008] For example, the peripheral edge of the mounting base extends outward with a protrusion that presses against the bracket and seals the gap between the mounting base and the mounting hole. This design not only ensures the stability of the connection between the bracket and the mounting base, preventing the mounting base from falling directly from the mounting hole, but also prevents liquids, oils, etc., flowing laterally on the bracket from flowing through the gap to the temperature measuring element by sealing the gap between the mounting base and the mounting hole, further avoiding the influence of liquids, oils, etc. on the temperature measuring element.

[0009] For example, a sealing element is sandwiched between the protrusion and the bracket. This arrangement, by sealing the gap between the fixing seat and the mounting hole, further prevents liquids, oils, etc. flowing laterally on the bracket from flowing through the gap to the temperature measuring element, thus avoiding any impact on the temperature measuring element and ensuring the accuracy of temperature measurement.

[0010] For example, the flame cap includes a central flame cap, which, together with the distributor seat, forms an inner annular mixing chamber. The central flame cap and the center of the inner annular mixing chamber are connected to form a temperature measuring channel. With this configuration, the temperature measuring channel is formed in the center of the mixing component, which avoids interference from the flame temperature and ensures the accuracy of the temperature measurement.

[0011] For example, the top surface of the light-transmitting element protrudes in an arc shape away from the support; or / and, the top surface of the light-transmitting element is provided with a transparent hydrophobic layer. This configuration prevents liquids, oil stains, etc. from accumulating on the top surface of the light-transmitting element and obscuring the detection signal, thereby avoiding affecting the accuracy of temperature measurement by the temperature measuring element.

[0012] For example, the heat spreader has a gap between the bottom periphery of the temperature measuring channel and the top surface of the light-transmitting element. This design allows liquids and oils to flow out through the gap, preventing the accumulation of liquids and oils in the temperature measuring channel from obstructing the measurement signal. It also facilitates the sliding off of liquids and oils that fall into the temperature measuring channel onto the top surface of the light-transmitting element, thus avoiding affecting the accuracy of the temperature measurement.

[0013] For example, the mounting base includes a first base and a second base. The temperature measuring element is mounted on the first base, and the light-transmitting element is mounted on the second base. The second base is detachably connected to the first base. With this configuration, by detachably connecting the second base to the first base, when installing the light-transmitting element and the temperature measuring element, it is only necessary to connect the second base to the first base; when disassembling the light-transmitting element and the temperature measuring element, the second base is separated from the first base. This facilitates the installation and disassembly of both the light-transmitting element and the temperature measuring element, and the structure is simple and easy to operate.

[0014] For example, both the first and second seats are detachably connected to the bracket; or, one of the first and second seats is integrally formed with the bracket. With this configuration, when both the first and second seats are detachably connected to the bracket, during installation, the first and second seats can be connected to the bracket separately, and then the first and second seats can be connected, facilitating positioning. During disassembly, either the first or second seat can be disassembled individually. When one of the first and second seats is integrally formed with the bracket, the installation process is simplified, saving installation time.

[0015] For example, the first seat is configured as a hollow seat with a receiving cavity, the hollow seat having a first end and a second end, the temperature measuring element being detachably connected to the first end and at least partially located within the receiving cavity, and the second seat being detachably connected to the second end. With this configuration, the temperature measuring element is detachably connected to the first end of the second seat, and the second seat is detachably connected to the second end, allowing for the removal of only the parts requiring maintenance or cleaning, eliminating the need for complete disassembly and replacement, simplifying operation, and reducing costs.

[0016] For example, a heat dissipation hole is provided between the first end and the second end of the hollow seat, and the heat dissipation hole connects to the outside and the receiving cavity. This arrangement helps to cool the temperature measuring element, avoids the temperature measuring element from being affected by ambient heat, ensures the operating temperature of the temperature measuring element, and improves the service life of the temperature measuring element. At the same time, the heat dissipation hole structure is easy to process and manufacture, saving costs.

[0017] According to another aspect of this utility model, a stove is provided, which includes a controller, a valve body, a timing module, and a burner as described above, wherein the temperature measuring element, the timing module, and the valve body are respectively connected to the controller. Since the burner described above has the aforementioned beneficial effects, the stove including the burner described above also has the aforementioned beneficial effects, which will not be elaborated further here.

[0018] This utility model description introduces a series of simplified concepts, which will be further explained in detail in the detailed description section. This utility model description is not intended to limit the key features and essential technical features of the claimed technical solution, nor is it intended to determine the scope of protection of the claimed technical solution.

[0032] In the following description, numerous details are provided to enable a thorough understanding of the present invention. However, those skilled in the art will appreciate that the following description merely illustrates preferred embodiments of the present invention, which may be practiced without one or more of these details. Furthermore, to avoid confusion with the present invention, some technical features well-known in the art have not been described in detail.

[0033] To fully understand the embodiments of this utility model, a detailed structure will be presented in the following description. Obviously, the implementation of the embodiments of this utility model is not limited to the specific details familiar to those skilled in the art. Preferred embodiments of this utility model are described in detail below; however, in addition to these detailed descriptions, this utility model may have other embodiments.

[0034] This invention provides a burner. The burner of this invention can be applied to stoves. The following will describe in detail one embodiment of the burner according to the accompanying drawings.

[0035] See also Figures 1 to 4The burner may include an injector 100, a support 200, a flame spreader 310, a flame cap 320, a light-transmitting element 400, a mounting base 500, and a temperature sensor 600 for sensing temperature signals. The injector 100 can be positioned by the support 200. The flame cap 320 and the flame spreader 310 can be closed to form a mixing element 300 with a mixing chamber 330. It should be noted that the positional relationship between the mixing element 300, the temperature sensor 600, and the light-transmitting element 400 and the support 200 is described based on the state when the burner is assembled and in use. The mixing element 300 may be located above the support 200. The injector 100 may be connected to the mixing chamber 330. The support 200 may be provided with a mounting hole 210. The mounting base 500 may pass through the mounting hole 210. The mounting base 500 may have a hollow portion 520. The temperature measuring element 600 may be at least partially located within the hollow portion 520. The light-transmitting element 400 may be disposed at the top 510 of the mounting base 500, obscuring the temperature measuring element 600 from above. A temperature measuring channel 340 may be formed on the mixing component 300, and the mounting base 500 may be at least partially located within the projection area of ​​the temperature measuring channel 340, allowing the temperature signal to pass through the light-transmitting element 400 and the temperature measuring channel 340. Specifically, the temperature measuring element 600 may be an infrared temperature probe. When the cookware is heated, the bottom of the pot can radiate infrared radiation (i.e., a temperature signal). The infrared radiation can pass through the temperature measuring channel 340 and the light-transmitting element 400 and be received by the infrared temperature probe, which can convert the infrared radiation into an electrical signal for temperature feedback. Of course, the temperature measuring element 600 can also be any other suitable structure, such as an ultrasonic temperature measuring probe. When the temperature measuring element 600 is an ultrasonic temperature measuring probe, the ultrasonic temperature measuring probe emits ultrasonic signals (ultrasonic waves) towards the bottom of the pot and receives the returned temperature signals. Both the emitted ultrasonic signals and the returned temperature signals can pass through the temperature measuring channel 340 and the light-transmitting element 400. The temperature measuring probe can convert the returned temperature signals into electrical signals for temperature feedback. The material of the light-transmitting element 400 can be inorganic quartz glass, etc., to ensure that the temperature signals penetrate the light-transmitting element 400 to reach the temperature measuring element 600 or the bottom of the pot. The material of the fixing base 500 can be metal, etc., to prevent liquids, oil stains, etc. from affecting the temperature measuring element 600. When the temperature measuring element 600 is an infrared temperature measuring probe, the fixing base 500 can also be made of a material with infrared radiation absorption and oil-proof properties.

[0036] In this burner, a temperature measuring element 600 and a light-transmitting element 400 are connected to a bracket 200 via a fixing base 500. The temperature measuring element 600 is at least partially located within the hollow portion 520. The light-transmitting element 400 is positioned at the top 510 of the fixing base 500, shielding the temperature measuring element 600 from above. This design allows both the temperature measuring element 600 and the light-transmitting element 400 to be simultaneously connected to the bracket 200, facilitating installation. Furthermore, when the burner is used to heat cookware on a stove, the temperature measuring element 600 remains non-contact with the bottom of the pot, preventing it from being affected by the flame and ensuring its integrity. This ensures the accuracy of temperature detection and avoids interference between the temperature measuring element 600 and the cookware, thereby expanding the types of cookware that can be used on the stove and broadening the applicability of the stove. On the other hand, since the temperature measuring element 600 is at least partially located within the hollow portion 520, and the light-transmitting element 400 blocks the temperature measuring element 600 from above, when the temperature measuring element 600 detects the temperature of the bottom of the pot, the light-transmitting element 400 can prevent liquids, oil stains, etc. from dripping vertically onto the temperature measuring element 600, thus avoiding any impact on the temperature measuring element 600 and ensuring the accuracy of the temperature measurement.

[0037] See Figure 3 Specifically, the light-transmitting element 400 can be connected to the top end 510 by adhesive. Of course, the light-transmitting element 400 can also be connected to the top end 510 by other methods, as long as the stability of the connection between the light-transmitting element 400 and the mounting base 500 is ensured and the light transmittance of the light-transmitting element 400 is not affected, making it suitable for various application scenarios. This not only facilitates cleaning of the light-transmitting element 400 but also prevents liquids, oil stains, etc., from accumulating inside the mounting base 500 and obstructing the detection signal, while also facilitating the installation and removal of the light-transmitting element 400.

[0038] See also Figure 3 and Figure 4 The mounting base 500 has a protrusion 501 extending outward from its periphery. The protrusion 501 presses against the bracket 200 and seals the gap between the mounting base 500 and the mounting hole 210. Specifically, the protrusion 501 can be a protrusion extending outward from the periphery of the mounting base 500, or it can be a flange structure extending outward from the periphery of the mounting base 500. Of course, the protrusion 501 can also be any other suitable structure to suit various application scenarios. It should be noted that the protrusion 501 can be pressed above or below the bracket 200, and its position can be adjusted according to the space above and below the bracket 200 to suit various application scenarios. In this way, not only is the stability of the connection between the bracket 200 and the fixed seat 500 ensured, preventing the fixed seat 500 from falling directly from the mounting hole 210, but the protrusion 501 also seals the gap between the fixed seat 500 and the mounting hole 210, preventing liquids, oils, etc. flowing laterally on the bracket 200 from flowing through the gap to the temperature measuring element 600, thus further avoiding the influence of liquids, oils, etc. on the temperature measuring element 600.

[0039] See again Figure 3 and Figure 4 A sealing element 700 can be sandwiched between the protrusion 501 and the bracket 200. The sealing element 700 can be made of rubber, which has good resilience. Under the compression of the protrusion 501 and the bracket 200, the rubber will undergo elastic deformation, tightly filling the microscopic gaps and macroscopic defects between the mating surfaces of the protrusion 501 and the bracket 200, thus forming a comprehensive, seamless seal. Of course, the sealing element 700 can also be made of other materials, such as silicone, to suit various application scenarios. In this way, by sealing the gap between the fixing seat 500 and the mounting hole 210, the sealing element 700 further prevents laterally flowing liquids, oil, etc., on the bracket 200 from flowing through the gap to the temperature measuring element 600, avoiding any impact on the temperature measuring element 600, thereby ensuring the accuracy of temperature measurement by the temperature measuring element 600.

[0040] See also Figures 1 to 8 The flame cap 320 may include a central flame cap 352. The central flame cap 352 and the distributor base 310 can enclose an inner annular mixing chamber 353. The central flame cap 352 and the inner annular mixing chamber 353 are connected at their centers to form a temperature measuring channel 340. In this way, the temperature measuring channel 340 is formed at the center of the mixing component 300, which can avoid flame temperature interference and ensure the accuracy of temperature measurement by the temperature measuring component 600.

[0041] Specifically, the mixing unit 300 may include an inner ring mixing unit 350 and an outer ring mixing unit 360. The inner ring mixing unit 350 is formed by enclosing the central flame cap 352 and the central flame distribution base 351. The outer ring mixing unit 360 is formed by enclosing the outer ring flame cap 362 and the outer ring flame distribution base 361. The ejector tube 100 may include an inner ring ejector tube 110 and an outer ring ejector tube 120. The positioning hole 240 may include a first hole 241 and a second hole 242. The inner ring ejector tube 110 passes through the first hole 241 and communicates with the inner ring mixing chamber 353 of the inner ring mixing unit 350. The outer ring ejector tube 120 passes through the second hole 242 and communicates with the outer ring mixing chamber 363 of the outer ring mixing unit 360. The outer ring mixing element 360 is fitted outside the inner ring mixing element 350, and the outer ring mixing element 360 and the inner ring mixing element 350 form concentric circles. A temperature measuring channel 340 can be formed at the center of the inner ring mixing element 350. The projection of the light-transmitting element 400 onto the plane containing the cross-section of the temperature measuring channel 340 can be located at the center of the temperature measuring channel 340. In this way, the temperature measuring element 600 can detect the center position of the bottom of the pot, improving the accuracy of the detection.

[0042] In one embodiment of this utility model, in conjunction with reference to Figure 3 and Figure 5The light-transmitting element 400 may have a light-transmitting sheet 410 and a connecting portion 420. The connecting portion 420 may be connected to the end face of the light-transmitting sheet 410 away from the cookware, and the connecting portion 420 may be inserted into the hollow portion 520 at its top end 510. The end face of the light-transmitting sheet 410 away from the cookware at least partially abuts against the top end 510 of the fixing base 500. In this way, the stability of the connection between the light-transmitting element 400 and the fixing base 500 is ensured, and liquids, oil stains, etc. are prevented from flowing in from the gap between the light-transmitting element 400 and the hollow portion 520.

[0043] See also Figure 1 , Figure 3 , Figure 4 and Figure 5 The top surface 401 of the light-transmitting element 400 can protrude in an arc shape away from the support 200. This allows liquids and oil to fall off along the arc-shaped top surface 401, preventing them from accumulating and obstructing the detection signal, thus avoiding affecting the accuracy of the temperature measurement by the temperature measuring element 600. Specifically, when the temperature measuring element 600 is an infrared temperature probe, the top surface 401 of the light-transmitting element 400 can protrude in an arc shape away from the support 200, making the light-transmitting element 400 a convex lens-like structure that is thicker in the middle and thinner at the edges. This allows the light-transmitting element 400 to focus the infrared radiation radiated from the bottom of the pot onto the infrared temperature measuring probe, enhancing the accuracy of the infrared temperature measurement.

[0044] For example, the top surface 401 of the light-transmitting element 400 may be provided with a transparent hydrophobic layer. Specifically, the transparent hydrophobic layer may be made of an inorganic material. In this way, the transparent hydrophobic layer prevents liquids, oil stains, etc. from adhering to the top surface 401 of the light-transmitting element 400 and blocking the detection signal, thereby avoiding affecting the accuracy of temperature measurement by the temperature measuring element 600.

[0045] See again Figure 3 The flame distributor 310 may have a gap between the bottom perimeter 311 of the temperature measuring channel 340 and the top surface 401 of the light-transmitting element 400. It should be noted that, in the height direction, the top surface 401 of the light-transmitting element 400 may be lower than the bottom of the flame distributor 310. This allows liquids and oils to flow out through the gap, preventing the accumulation of liquids and oils within the temperature measuring channel 340 from obstructing the detection signal. It also facilitates the sliding down of liquids and oils that fall from the temperature measuring channel 340 onto the top surface 401 of the light-transmitting element 400, thus avoiding any impact on the accuracy of the temperature measurement by the temperature measuring element 600.

[0046] In the embodiment not shown in the figure, the light-transmitting element 400 and at least part of the fixing seat 500 can be located inside the temperature measuring channel 340, and the light-transmitting element 400 and at least part of the fixing seat 500 are spaced apart from the wall of the temperature measuring channel 340 to ensure that liquids, oils, etc. can flow out from the gap. This not only avoids the accumulation of liquids, oils, etc. in the temperature measuring channel 340 from obstructing the detection signal, but also facilitates the sliding of liquids, oils, etc. that fall into the top surface 401 of the light-transmitting element 400 from the temperature measuring channel 340, so as to avoid affecting the accuracy of temperature measurement by the temperature measuring element 600.

[0047] See also Figure 4 , Figure 6 and Figure 7 The mounting base 500 may include a first base 530 and a second base 540. A temperature measuring element 600 may be mounted on the first base 530. A light-transmitting element 400 may be mounted on the second base 540. The second base 540 is detachably connected to the first base 530. In one embodiment of this invention, when the light-transmitting element 400 and the temperature measuring element 600 are connected to the first base 530 via the second base 540, they may be positioned above and below the bracket 200, respectively. Alternatively, some of the temperature measuring elements 600 may be located above the bracket 200, ensuring that the temperature measuring elements 600 are below the light-transmitting element 400. Thus, by detachably connecting the second base 540 to the first base 530, when installing the light-transmitting component 400 and the temperature-measuring component 600, it is only necessary to connect the second base 540 to the first base 530. When disassembling the light-transmitting component 400 and the temperature-measuring component 600, the second base 540 can be separated from the first base 530. This facilitates the installation and disassembly of both the light-transmitting component 400 and the temperature-measuring component 600, and the structure is simple and easy to operate.

[0048] For example, both the first seat 530 and the second seat 540 are detachably connected to the bracket 200. Thus, during installation, the first seat 530 and the second seat 540 can be connected to the bracket 200 respectively, and then the first seat 530 and the second seat 540 can be connected for easy positioning. During disassembly, the first seat 530 or the second seat 540 can be disassembled individually.

[0049] Exemplarily, one of the first base 530 and the second base 540 is integrally formed with the bracket 200. In some embodiments, the first base 530 can be integrally formed with the bracket 200, and during installation, only the second base 540 needs to be connected to the first base 530 to position the second base 540 on the bracket 200. In some embodiments, the second base 540 can be integrally formed with the bracket 200, and during installation, only the first base 530 needs to be connected to the second base 540 to position the first base 530 on the bracket 200. This simplifies the installation process and saves installation time.

[0050] See also Figure 4 and see Figure 6The first seat 530 can be configured as a hollow seat with a receiving cavity 533. The hollow seat can have a first end 531 and a second end 532. The temperature measuring element 600 is detachably connected to the first end 531 and is at least partially located within the receiving cavity 533. Specifically, the temperature measuring element 600 can be connected to the first end 531 by a threaded connection for easy installation or removal. Of course, the temperature measuring element 600 can also be connected to the first end 531 by other means, such as a snap-fit ​​connection, to suit various application scenarios. The second seat 540 is detachably connected to the second end 532. Thus, the temperature measuring element 600 is detachably connected to the first end 531 of the second seat 540, and the second seat 540 is detachably connected to the second end 532. Only the parts requiring maintenance or cleaning can be removed, without the need for complete disassembly and replacement, which is convenient and reduces costs.

[0051] In one embodiment of this utility model, in conjunction with reference to Figures 4 to 7 The second end 532 of the first seat 530 may be provided with an internal thread structure 534. The second seat 540 may have a third end 541 and a fourth end 542. The third end 541 may be provided with an external thread structure 543, and the light-transmitting element 400 may be connected to the fourth end 542. The second seat 540 may be threadedly connected to the internal thread structure 534 of the first seat 530 through the external thread structure 543. Specifically, the protrusion 501 can be disposed on the second seat 540. The third end 541 of the second seat 540 can pass through the mounting hole 210 of the bracket 200 from above. The fourth end 542 is positioned above the bracket 200 through the protrusion 501. The third end 541 of the second seat 540 can extend from below the bracket 200 into the receiving cavity 533 and be threadedly connected to the internal thread structure 534 of the first seat 530 through the external thread structure 543. As the first seat 530 and the second seat 540 are locked together through the threaded connection, the second end 532 can abut against the bracket 200, and at the same time drive the protrusion 501 to squeeze the bracket 200, so that the seal 700 between the protrusion 501 and the bracket 200 is squeezed, tightly filling the micro gaps and macro defects between the mating surface of the protrusion 501 and the mating surface of the bracket 200, thereby forming an all-round, dead-angle-free seal. In this way, when the first 530 and the second 540 are installed, the mounting hole 210 can be blocked at the same time, which simplifies the operation process. The structure is simple, easy to install or disassemble, and easy to process and manufacture, thus saving costs.

[0052] In an embodiment not shown in the figure, the second end 532 of the first seat 530 can be provided with a flange structure having a connection hole. A protrusion 501 can be provided on the second seat 540, and the protrusion 501 can also be a flange structure with a connection hole. The third end 541 of the second seat 540 can pass through the mounting hole 210 of the bracket 200 from above. The fourth end 542 is positioned above the bracket 200 via the protrusion 501. The second end 532 of the first seat 530 can abut against the third end 541 of the second seat 540 from below the bracket 200, aligning the connection holes of the two flange structures with the connection holes on the bracket 200. Fasteners pass through each connection hole to connect the flange structures on the first seat 530, the flange structures on the second seat 540, and the bracket 200, causing the seal 700 between the protrusion 501 and the bracket 200 to be compressed, tightly filling the microscopic gaps and macroscopic defects between the mating surfaces of the protrusion 501 and the bracket 200, thereby forming an all-around, dead-angle-free seal. Fasteners can be screws or bolts, etc. Thus, when installing the first bracket 530 and the second bracket 540, the mounting hole 210 can be sealed simultaneously, simplifying the operation process. The structure is simple, easy to install or disassemble, and easy to manufacture, saving costs. Of course, the first bracket 530 and the second bracket 540 can also be connected in other ways to suit various application scenarios.

[0053] See again Figure 4 and see Figure 6 A heat dissipation hole 535 can be provided between the first end 531 and the second end 532 of the hollow base. The heat dissipation hole 535 can connect to the outside and the receiving cavity 533. Specifically, the number of heat dissipation holes 535 can be one, two, or more. When there are multiple heat dissipation holes 535, they can be spaced apart circumferentially along the first base 530 to improve the heat dissipation effect. This helps to cool down the temperature measuring element 600, avoids the temperature measuring element 600 from being affected by ambient heat in terms of its temperature measuring accuracy, ensures the operating temperature of the temperature measuring element 600, and improves its service life. At the same time, the structure of the heat dissipation hole 535 is easy to process and manufacture, saving costs.

[0054] In an embodiment not shown in the figure, the mounting base 500 can also be an integral structure, which saves installation time and facilitates manufacturing.

[0055] In some embodiments, in conjunction with reference Figure 1 , Figure 3 , Figure 4 and Figure 8The bracket 200 may have a plate-shaped body 220 and a support leg 230. One end of the support leg 230 may be disposed on the plate-shaped body 220. A mounting hole 210 may be disposed on the plate-shaped body 220. A fixing seat 500 may be positioned on the plate-shaped body 220 through the mounting hole 210. The plate-shaped body 220 may have a positioning hole 240, and a positioning boss may be protruding on the outer wall surface of the ejector tube 100. The ejector tube 100 passes through the positioning hole 240 from below the bracket 200 and is positioned on the plate-shaped body 220 through the positioning boss. In this way, the support leg 230 supports the plate-shaped body 220, ensuring that the bracket 200 positions the fixing seat 500 and the ejector tube 100, and the plate-shaped body 220 absorbs some liquids and oils, preventing liquids and oils from affecting the temperature measuring element 600. Specifically, the bracket 200 may be made of stainless steel or other materials to ensure high temperature resistance and corrosion resistance.

[0056] In some embodiments, the gas mixing component 300 is detachably connected to the ejector tube 100. For example, the gas mixing component 300 can be connected to the ejector tube 100 via a snap-fit ​​connection, which not only ensures the stability of the connection between the gas mixing component 300 and the ejector tube 100, but also allows for quick disassembly of the gas mixing component 300 without the need for tools, thus facilitating the cleaning of the light-transmitting component 400. Of course, the gas mixing component 300 and the ejector tube 100 can also be connected in other ways, as long as the stability of the connection between the gas mixing component 300 and the ejector tube 100 is ensured.

[0057] According to another aspect of this utility model, a cooktop is provided. The cooktop may include a controller, a valve body, a timing module, and a burner as described above. The temperature measuring element 600, the timing module, and the valve body can be connected to the controller respectively. Specifically, the controller and the timing module are configured as a microcontroller, achieving a high degree of integration and reducing costs. Since the burner described above has the aforementioned beneficial effects, the cooktop including the burner described above also has the aforementioned beneficial effects, which will not be elaborated further here.

[0058] In some embodiments, the cooktop may further include a bottom shell and a panel, which may be fitted together to form a mounting cavity. A bracket 200 is located within the mounting cavity, and the end of a support leg 230 away from the plate-like body 220 is fixed to the bottom wall of the bottom shell. The panel may have a through hole for the mounting base 500 to pass through. The temperature sensor 600 may be located within the mounting cavity to further prevent liquids and oils from affecting the temperature sensor 600. The light-transmitting element 400 may be located outside the mounting cavity to facilitate cleaning of the light-transmitting element 400.

[0059] In some embodiments, the timing module may include a timing element and a prompting element. The timing element may be a timer, and the prompting element may be a warning light, a voice player, or a display screen, etc. In this way, the working time of the stove is accumulated by the timing element, which has a simple structure and saves costs; the prompting element can adopt various structures to issue a prompt to clean the light-transmitting element 400, which is suitable for various scenarios.

[0060] See Figure 9 The control method used in the stove of this utility model may include the following steps:

[0061] S1. Temperature measurement: After ignition, the temperature of the bottom of the pot is detected by the temperature measuring element 600 to obtain the temperature value of the bottom of the pot;

[0062] S2, Over-temperature shutdown: Compares the bottom temperature value with the preset temperature value, and shuts off the valve when the bottom temperature value reaches or exceeds the preset temperature value;

[0063] S3, Timing: Accumulates the working time of the stove through the timing module and compares the working time with the preset time value;

[0064] S4. Prompt: When the working time reaches the preset time value, issue a prompt to clean the light-transmitting component 400.

[0065] Thus, based on the temperature of the pot bottom detected by the temperature measuring element 600, it can determine whether there is a situation such as burner dry burning or accidental flameout. When these situations occur, the controller can close the valve body immediately to avoid safety hazards. In addition, the timer module accumulates the working time of the stove. When the working time reaches the preset value, it issues a prompt to clean the light-transmitting element 400 to prevent liquids, oil stains, etc. from accumulating on the light-transmitting element 400 and blocking the detection signal.
