Description

Technical Field

[0001] This utility model relates to the field of cooking utensils technology, specifically to a stove. Background Technology

[0002] As the usage rate of gas stoves increases, people's requirements for their safety are also rising. Existing gas stoves are typically equipped with temperature sensors to detect the temperature of the cookware and determine whether there are issues such as dry burning or accidental flameout. In such cases, the gas supply can be cut off immediately to avoid safety hazards.

[0003] Most gas stoves on the market currently use an external 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, in case of accidental flameout or prolonged periods without a pot on the stove, the gas supply can be cut off immediately based on the external temperature sensor's readings to prevent accidents. However, external 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, external temperature sensors are susceptible to flame interference, which can cause them to inaccurately detect the bottom temperature of the cookware, leading to abnormal flameouts. Utility Model Content

[0004] In order to at least partially solve the problems existing in the prior art, according to one aspect of the present invention, a stove is provided, the technical solution of which is as follows.

[0005] The cooktop includes a bottom shell, a panel, burners, a temperature sensor, a control valve, and a gas supply line. The bottom shell encloses and forms an open mounting cavity. The panel is placed on the bottom shell and covers the opening. The temperature sensor is located below the panel and is connected to the burners. The control valve is connected to the gas supply line and controls the opening and closing of the gas supply line based on the temperature sensed by the temperature sensor.

[0006] The stove of this utility model can detect the temperature of the pot bottom by sensing the temperature of the burner head through a temperature sensing element (i.e., indirectly detecting the temperature of the pot). The temperature sensing element is located below the panel and is not affected by the flame, which not only ensures the accuracy and speed of temperature detection, but also prevents interference between the temperature sensing element and the pot even when using a pointed-bottom pot, thus expanding the applicability of the stove.

[0007] For example, the burner head includes a bracket and an ejector tube. The bracket is located within the mounting cavity, the ejector tube is positioned by the bracket, and the temperature sensor is mounted on the bracket. With this configuration, since the temperature of the bracket is related to the temperature of the pot bottom, the temperature of the pot bottom can be detected directly or indirectly by sensing the temperature of the bracket (i.e., indirectly detecting the pot temperature). The temperature sensor is not affected by the flame, ensuring not only the accuracy and speed of temperature detection, but also that the temperature sensor will not interfere with the pot even when using a pointed-bottom pot, thus expanding the applicability of the stove.

[0008] For example, at least a portion of the temperature sensor forms surface contact with the support. With this configuration, the temperature of the support is related to the temperature of the pot bottom, allowing the temperature sensor to detect the pot bottom temperature (i.e., indirectly detect the pot temperature) by sensing the temperature of the support. The temperature sensor is not affected by the flame, ensuring not only the accuracy and speed of temperature detection, but also preventing interference with the pot even when using a pointed-bottom pot, thus expanding the applicability of the stove.

[0009] For example, the temperature sensor is connected to the bracket via a fixed structure. This arrangement facilitates the installation of the temperature sensor; furthermore, since the temperature of the bracket is related to the temperature of the pot bottom, the temperature of the pot bottom can be detected by sensing the temperature of the bracket through the temperature sensor (i.e., indirectly detecting the temperature of the cookware). The temperature sensor is not affected by the flame, ensuring not only the accuracy and speed of temperature detection, but also that the temperature sensor will not interfere with the cookware even when using a pointed-bottom pot, thus expanding the applicability of the stove.

[0010] For example, the temperature sensing element has a heat-conducting portion, which forms surface contact with a portion of the bracket through a fixing structure; or, the heat-conducting portion is in contact with a portion of the fixing structure. This configuration, by fixing the heat-conducting portion to the bracket through the fixing structure, ensures surface contact between the heat-conducting portion and the bracket, guaranteeing the accuracy and speed of temperature detection; the heat-conducting portion indirectly senses the temperature of the bracket through the fixing structure, ensuring the accuracy and speed of temperature detection; thus, the temperature sensing element can be applied to a wider range of scenarios.

[0011] For example, the ejector tube includes an inner ring ejector tube and an outer ring ejector tube. Both the inner and outer ring ejector tubes are positioned by a bracket, and the inner and outer ring ejector tubes are spaced apart in a first direction. At least a portion of the temperature sensing element forms surface contact with the bracket, and the surface contact location is between the inner and outer ring ejector tubes. The first direction is the length direction of the bracket. With this configuration, at least a portion of the temperature sensing element forms surface contact with the bracket that positions the inner and outer ring ejector tubes. Since the temperature of the bracket is related to the temperature of the pot bottom, the temperature of the pot bottom can be detected by sensing the temperature of the bracket (i.e., indirectly detecting the temperature of the cookware). The temperature sensing element is not affected by the flame, which not only ensures the accuracy and speed of temperature detection, but also ensures that the temperature sensing element will not interfere with the cookware even when using a pointed-bottom pot, thus expanding the applicability of the stove.

[0012] For example, the cooktop also includes a burner cap, and the ejector tube has a protruding section extending beyond the support. The burner cap is fitted onto the protruding section and divides the protruding section into a heat transfer section and a heat conduction section. A portion of the burner cap is fitted onto the heat transfer section. With this configuration, based on the arrangement of the heat transfer and heat conduction sections, when heating a pot, the heat from the bottom of the pot can be transferred to the heat transfer section via the burner cap, and then to the support via the heat conduction section. Since the temperature sensor is located on the support, the temperature of the bottom of the pot can be detected by sensing the temperature of the support (i.e., indirectly detecting the temperature of the pot). The temperature sensor is not affected by the flame, and even when using a pointed-bottom pot, the temperature sensor will not interfere with the pot, thus expanding the applicability of the cooktop.

[0013] For example, the outer surface of the heat transfer section has a first area S1, and the outer surface of the heat conduction section has a second area S2, where 0.8S1≤S2≤1.5S1. This configuration, based on the relationship between the first area S1 and the second area S2, ensures that the heat from the bottom of the pot can be fully transferred to the support by the heat conduction section, guaranteeing the accuracy and speed of temperature detection.

[0014] For example, the burner head includes an ejector tube, at least a portion of which is located within a mounting cavity. A temperature sensing element is disposed on the ejector tube, and at least a portion of the temperature sensing element is in contact with the ejector tube. This arrangement allows the temperature sensing element to contact the ejector tube. When heating a cookware, the temperature of the bottom of the cookware can be transferred to the ejector tube, and the temperature of the bottom of the cookware can be indirectly detected by sensing the temperature of the ejector tube. This not only avoids direct contact between the temperature sensing element and the cookware, preventing interference and allowing the burner head to be used with different types of cookware, but also avoids the temperature sensing element being too close to the flame of the burner head, thus preventing the temperature sensing element from being affected by the flame. This effectively ensures the accuracy of the temperature sensing results, thereby improving the reliability and safety of the stove.

[0015] For example, the burner head includes an ejector tube and a heat conductor, the ejector tube being connected to the heat conductor, and at least a portion of the temperature sensing element forming surface contact with the heat conductor. With this configuration, at least a portion of the temperature sensing element forms surface contact with the heat conductor connected to the ejector tube. Since the temperature of the heat conductor is related to the temperature of the pot bottom, the temperature of the pot bottom can be detected by sensing the temperature of the heat conductor (i.e., indirectly detecting the pot temperature). The temperature sensing element is not affected by the flame, ensuring not only the accuracy and speed of temperature detection, but also that even when using a pointed-bottom pot, the temperature sensing element will not interfere with the pot, expanding the applicability of the stove.

[0016] For example, the surface contact location is within the annular region, the outer contour of the ejector tube forms the inner ring of the annular region, and the outer contour of the ejector tube offset by a distance L forms the outer ring of the annular region, where L ≤ 40 mm. This configuration, with L within this range, further ensures the accuracy and speed of temperature detection.

[0017] For example, the burner head also includes a bracket for positioning the ejector tube. The bracket has a plate-shaped body through which the ejector tube passes. The plate-shaped body forms a heat-conducting element, and the surface contact position is located on the plate-shaped body. This arrangement not only facilitates the positioning of the ejector tube, but also, since the temperature of the pot bottom above the burner head is transferred to the plate-shaped body through the ejector tube when the pot is heated, the temperature of the plate-shaped body is correlated with the temperature of the pot bottom, ensuring the accuracy and speed of temperature detection.

[0018] For example, the burner head also includes a bracket for positioning the ejector tube. The bracket has a plate-shaped body through which the ejector tube passes, and the heat-conducting element is positioned above the plate-shaped body; or, the heat-conducting element is positioned below the plate-shaped body. With this configuration, when the heat-conducting element is positioned above the plate-shaped body, installation is convenient; when the heat-conducting element is positioned below the plate-shaped body, the plate-shaped body can shield the heat-conducting element, effectively preventing leaked liquid from contacting the temperature sensing element and affecting its accuracy and lifespan.

[0019] For example, the stove also includes a burner base and a burner cap. The burner cap and burner base together form a mixing chamber for communication with the injector tube. The burner base has a bottom surface, and the temperature sensing element has a temperature sensing surface located below the bottom surface. With this configuration, a temperature sensing element for sensing the temperature of the injector tube is provided. Since the temperature sensing element is located below the bottom surface, when the cookware is heated, the heat from the bottom of the cookware can be transferred to the injector tube through the burner cap and burner base. Therefore, by sensing the temperature of the injector tube, the temperature of the bottom of the cookware can be detected (i.e., indirectly detecting the temperature of the cookware). This not only prevents the temperature sensing element from being affected by the flame, ensuring the accuracy of temperature detection, but also avoids interference between the temperature sensing element and the cookware, thereby expanding the types of cookware that can be used on the stove and broadening the applicability of the stove.

[0020] For example, in a direction perpendicular to the mounting plane of the burner seat, there is a first gap Z1 between the bottom surface and the temperature sensing surface, where the first gap Z1 is 1mm to 5mm. With this configuration, within the range of the first gap Z1, the heat from the bottom of the cookware can be transferred to the injector tube through the burner cap and the burner seat. Thus, by sensing the temperature of the injector tube, the temperature of the bottom of the cookware can be detected (i.e., indirectly detecting the temperature of the cookware). This not only prevents the temperature sensing element from being affected by the flame, ensuring the accuracy of temperature detection, but also avoids interference between the temperature sensing element and the cookware, thereby expanding the types of cookware that can be used on the stove and broadening the applicability of the stove.

[0021] For example, the burner head includes a bracket and an ejector tube. The bracket has a first hole and a sensing mounting position. The ejector tube passes through the first hole, and the temperature sensing element is located at the sensing mounting position. This configuration not only allows the ejector tube to be positioned by the bracket, but also enables the heat from the ejector tube to be transferred to the bracket. Since the sensing mounting position is located on the bracket, the temperature of the ejector tube can be indirectly sensed by sensing the temperature of the bracket, thereby achieving the detection of the pot bottom temperature. This prevents the temperature sensing element from being affected by the flame, ensuring the accuracy of temperature detection, and also avoids interference between the temperature sensing element and the cookware. This expands the types of cookware that can be used on the stove and broadens the applicability of the stove.

[0022] For example, the burner head also includes a thermocouple with a second hole on the bracket. The thermocouple passes through the second hole, and the center of the second hole is located on a first circle with radius R1 centered at the sensing installation position. The center of the second hole and the center of the first hole are separated by a first distance L1, where R1 > L1. This arrangement not only ensures the normal operation of the thermocouple but also avoids the thermocouple being too close to the sensing installation position of the temperature sensing element, thereby preventing the heat generated by the thermocouple from being transferred to the sensing installation position and affecting the detection results of the temperature sensing element.

[0023] For example, the radius R1 is 30mm to 45mm. With this setting, the radius R1 is within this range, which further avoids the heat generated by the thermocouple being transferred to the sensing mounting position and affecting the detection results of the temperature sensing element.

[0024] For example, the first distance L1 is 15mm to 18mm. With this setting, the first distance L1 is within this range, ensuring the normal operation of the thermocouple, allowing the thermocouple to monitor the temperature of the combustion flame in the inner ring ejector tube in real time, and ensuring the efficient and safe operation of the stove.

[0025] For example, the burner head also includes an ignition needle, and the bracket has a third hole for the ignition needle to pass through. The center of the third hole is located on a second circle with radius R2 centered at the sensing mounting position, and the center of the third hole is at a second distance L2 from the center of the first hole, where R2 > L2. This configuration not only ensures the normal operation of the ignition needle but also prevents the ignition needle from being too close to the sensing mounting position of the temperature sensor, thus preventing the heat generated by the ignition needle from being transferred to the sensing mounting position and affecting the detection result of the temperature sensor.

[0026] For example, the radius R2 is 30mm to 45mm. With this setting, the radius R2 is within this range, which avoids the heat generated by the ignition needle being transferred to the sensing mounting position and affecting the detection results of the temperature sensing element.

[0027] For example, the second distance L2 is 5mm to 11mm. With this setting, the second distance L2 is within this range, ensuring that the ignition needle works normally, so that the ignition needle can accurately ignite the gas and ensure that the burner can start combustion.

[0028] For example, the cooktop also includes a liquid-holding tray with a through hole on the panel. The liquid-holding tray is supported on the panel and covers the through hole. The liquid-holding tray forms a liquid-holding cavity. The temperature-sensing element has a temperature-sensing surface located below the liquid-holding tray. With this configuration, the temperature-sensing surface is located below the liquid-holding tray. By sensing the temperature of the ejector tube through the temperature-sensing element, the temperature of the bottom of the pot can be detected (i.e., indirect detection of the pot temperature). This not only prevents the temperature-sensing element from being affected by the flame, ensuring the accuracy of temperature detection, but also avoids interference between the temperature-sensing element and the pot, thereby expanding the types of pots that can be used on the cooktop and broadening the applicability of the cooktop.

[0029] For example, the furnace head includes an ejector tube, and a through hole may be provided on the liquid-holding tray, through which the ejector tube passes; wherein, a leak-proof structure is provided at the through hole location, and the mounting cavity is isolated from the liquid-holding cavity by the leak-proof structure. This configuration, by providing a leak-proof structure, effectively prevents liquid collected in the liquid-holding cavity from seeping into the mounting cavity through the through hole, not only avoiding liquid entering the mounting cavity and affecting the detection results of the temperature sensing element, but also reducing the possibility of safety risks.

[0030] For example, the burner head includes an ejector tube and a bracket. The ejector tube is positioned by the bracket, which is located below the liquid-holding tray. The ejector tube passes through the bracket and the liquid-holding tray sequentially from bottom to top, and the temperature-sensing surface is disposed on the bracket. With this configuration, since the temperature of the bracket is related to the temperature of the pot bottom, the temperature of the pot bottom can be detected by sensing the temperature of the bracket (i.e., indirectly detecting the pot temperature). The temperature-sensing element is not affected by the flame, ensuring not only the accuracy and speed of temperature detection, but also that the temperature-sensing element will not interfere with the pot even when using a pointed-bottom pot, thus expanding the applicability of the stove.

[0031] For example, the liquid-holding tray has a first tray and a second tray, the second tray being lower than the first tray, and the first tray being closer to the center of the liquid-holding tray than the second tray. The orthographic projection of the temperature-sensing surface onto the plane containing the first tray falls within the first tray. With this configuration, because the second tray is lower than the first tray, the liquid on the first tray can flow to the second tray, reducing the influence of the liquid temperature on the temperature-sensing element and further ensuring the accuracy of the temperature-sensing results.

[0032] For example, a second distance Z2 is provided between the temperature sensing surface and the lower surface of the first plate, the second distance Z2 being 5mm to 12mm. This arrangement, with the second distance Z2 within this range, not only prevents the temperature of the first plate or the temperature of the liquid remaining on the first plate from affecting the detection results of the temperature sensing element due to the first plate being too close to the temperature sensing surface, but also facilitates the formation of a first cavity between the temperature sensing surface and the lower surface of the first plate. Heat generated by the ejector tube can then dissipate outwards from this first cavity, preventing excessive heat concentration that could affect the measurement results of the temperature sensing element, thereby ensuring the accuracy of the temperature sensing element's detection results.

[0033] For example, the liquid collection tray also has a third tray portion, which is higher than the second tray portion, and the second tray portion is connected between the first tray portion and the third tray portion. In this configuration, the second tray portion is lower than the first tray portion and the third tray portion, and the second tray portion forms the bottom of the liquid collection tray, preventing the liquid collected by the second tray portion from flowing around and affecting other components.

[0034] For example, a protrusion is formed in the liquid-collecting tray at the position corresponding to the temperature-sensing element. The protrusion protrudes away from the temperature-sensing element and forms a cavity. This configuration has several advantages. First, the protrusion protrudes away from the temperature-sensing element, allowing the liquid remaining on the protrusion to flow to the first and second trays, further reducing the influence of the liquid temperature on the temperature-sensing element. It also keeps the protrusion further away from the sensing surface, preventing the temperature of the protrusion or the temperature of the small amount of liquid remaining on it from affecting the detection results. Second, the cavity formed in the protrusion allows heat generated by the ejector tube to dissipate into and outward through the cavity, preventing excessive heat concentration that could affect the measurement results of the temperature-sensing element, thus ensuring the accuracy of the detection results. Furthermore, when the temperature-sensing element is fixed by fasteners, the protrusion can avoid interfering with the fasteners.

[0035] For example, the protrusion has a convex top wall, the temperature sensing element has a temperature sensing surface, and a third distance Z3, ranging from 4mm to 14mm, exists between the lower surface of the convex top wall and the temperature sensing surface. This arrangement, with the third distance Z3 within this range, not only allows liquid remaining on the protrusion to flow to the first and second disks, further reducing the influence of the liquid temperature on the temperature sensing element, but also prevents the temperature of the protrusion or the temperature of a small amount of liquid remaining on the protrusion from affecting the detection results of the temperature sensing element, thereby ensuring the accuracy of the detection results.

[0036] For example, the orthographic projection of the center of the temperature-sensing surface onto the plane of the panel is located within the through hole, and along the length of the panel, there is a third distance L3 between the center of the temperature-sensing surface and the wall of the through hole, the third distance L3 being 40mm to 90mm. This configuration, with the third distance L3 within a predetermined range, avoids the heat of the panel affecting the detection results of the temperature-sensing element, thereby ensuring the accuracy of the detection results.

[0037] For example, the bottom shell has a cavity bottom wall opposite to the panel, the cavity bottom wall has a first region and a second region, and the temperature sensing element has a temperature sensing surface, which is spaced apart from the first region and the second region. This arrangement, with the sensing surface spaced apart from the first and second regions, ensures that the temperature sensing element has sufficient heat dissipation space, preventing heat generated by the temperature sensing element from accumulating nearby and affecting or damaging the element. This effectively improves the detection accuracy and service life of the temperature sensing element, and enhances the safety and reliability of the stove.

[0038] For example, in a direction perpendicular to the panel, the first region is farther away from the panel than the second region, and there is a fourth gap Z4 between the temperature sensing surface and the first region, the fourth gap Z4 being 35mm to 80mm. With this configuration, the fourth gap Z4 is within this range, which can prevent heat from accumulating near the temperature sensing element, thereby avoiding any impact or damage to the temperature sensing element.

[0039] For example, the control valve is at least partially positioned corresponding to the first region, and the first region has a first heat dissipation hole for dissipating heat from at least part of the control valve. This arrangement allows the first heat dissipation hole to dissipate the heat generated by at least part of the control valve, preventing heat accumulation from affecting or damaging components such as the control valve and temperature sensor. This effectively improves the detection accuracy of the temperature sensor and extends the service life of the temperature sensor and at least part of the control valve, thereby enhancing the safety and reliability of the stove.

[0040] For example, the bottom shell has a cavity sidewall located between the cavity bottom wall and the panel. The second region has an inner region and a peripheral region, with the peripheral region closer to the cavity sidewall than the inner region. The projection of the temperature sensing element onto the plane of the cavity bottom wall is located in the inner region, and a second heat dissipation hole is provided on the inner region for heat dissipation of the temperature sensing element. This configuration allows the heat generated by the temperature sensing element to be promptly discharged from the mounting cavity through the second heat dissipation hole in the inner region. Furthermore, the temperature sensing element can be located above the inner region, allowing the hot airflow in the mounting cavity to be quickly discharged along a shorter airflow path, avoiding overheating that may occur due to heat concentration in the area near the temperature sensing element, further improving the accuracy and service life of the temperature sensing element.

[0041] For example, the burner head includes an ejector tube and a bracket. The ejector tube is positioned by the bracket, and a thermocouple is mounted on the bracket. A third heat dissipation hole is provided on the outer perimeter for heat dissipation of the thermocouple. This configuration, by mounting the ejector tube and thermocouple on the bracket, optimizes the overall structural design of the burner head, making it more compact and stable. Furthermore, the positioning of the ejector tube and thermocouple by the bracket simplifies the burner head assembly process, reducing assembly steps and time, and facilitating subsequent maintenance and replacement, significantly reducing maintenance costs. Moreover, the heat generated by the thermocouple can be dissipated through the third heat dissipation hole, preventing heat accumulation from affecting and damaging the temperature sensing element and thermocouple, effectively improving the detection accuracy of the temperature sensing element and the service life of the temperature sensing element and thermocouple, thereby enhancing the safety and reliability of the stove.

[0042] For example, the temperature sensing element includes a heat-conducting part, a sensing part, and a signal transmission line. The heat-conducting part has a temperature-sensing surface, and the sensing part is connected to the heat-conducting part. The sensing part acquires the temperature information of the burner head through the temperature-sensing surface, and the signal transmission line is connected to the sensing part to transmit the temperature information outward. With this configuration, the temperature-sensing surface on the heat-conducting part can contact at least a portion of the burner head, thereby transferring heat to the sensing part. The sensing part can convert the heat into specific temperature information and transmit it to the outside through the signal transmission line, thus realizing the detection and monitoring of the burner head temperature. Direct contact between the temperature sensing element and at least a portion of the burner head avoids interference from the external environment, effectively ensuring the accuracy of the temperature measurement results. The temperature sensing element can indirectly detect the temperature of the pot bottom by detecting the temperature of one of the bracket, the ejector tube, and the heat-conducting part, avoiding the influence of the flame on the temperature sensing element, improving the safety and reliability of the stove's use. Even when using a pointed-bottom pot, the temperature sensing element will not interfere with the pot, expanding the applicability of the stove.

[0043] For example, the sensing unit includes a housing and a sensing chip, with the sensing chip disposed within the housing and one end of a signal transmission line connected to the sensing chip. This arrangement allows the sensing chip to be housed within the housing, effectively protecting it from external environmental influences such as dust, moisture, or mechanical impact, significantly improving its lifespan and reliability. Furthermore, the direct connection between the sensing chip and the signal transmission line greatly reduces signal transmission delay, enabling the temperature sensing chip to quickly respond to temperature changes and transmit temperature information outwards.

[0044] Exemplarily, the temperature sensing element is positioned within the mounting cavity by a fixing assembly; the fixing assembly has a pressing member and a fastening structure, the fastening structure being connected to the pressing member; the temperature sensing element has a sensing surface and a opposing surface, the sensing surface sensing the temperature of the burner head, and the opposing surface facing the sensing surface; wherein, the pressing member is pressed against the opposing surface by the fastening structure, causing the sensing surface to form surface contact with at least a portion of the burner head. With this configuration, the fixing assembly can apply force to the temperature sensing element, ensuring that the sensing surface of the temperature sensing element is tightly fitted with at least a portion of the burner head, thereby allowing the temperature of the burner head to be sensed by the temperature sensing element. Furthermore, based on the design of the pressing member and the fastening structure, situations where the sensing surface of the temperature sensing element is not tightly fitted to the burner head, or even detached, can be avoided, effectively improving the accuracy and reliability of temperature sensing.

Detailed Implementation

[0111] 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.

[0112] 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.

[0113] An embodiment of this utility model provides a stove. The stove according to an embodiment of this utility model will be described in detail below with reference to the accompanying drawings.

[0114] See also Figures 1 to 61 The cooktop 1 includes a bottom shell 10, a panel 20, a burner 30, a temperature sensor 40, a control valve 50, and a gas pipeline. The bottom shell 10 encloses a mounting cavity 110 with an opening 120. The panel 20 is disposed on the bottom shell 10 and covers the opening 120. The temperature sensor 40 is located below the panel 20 and is connected to the burner 30. The control valve 50 is connected to the gas pipeline and controls the opening and closing of the gas pipeline based on the temperature sensed by the temperature sensor 40. Specifically, the control valve 50 is configured to disconnect the gas pipeline when the temperature value sensed by the temperature sensor 40 changes beyond a threshold within a preset time period; or / and when the temperature value sensed by the temperature sensor 40 is higher than a preset temperature.

[0115] The stove 1 of this utility model can detect the temperature of the bottom of the pot by sensing the temperature of the burner 30 through the temperature sensing element 40 (i.e., indirectly detecting the temperature of the pot). The temperature sensing element 40 is located below the panel 20 and is not affected by the flame, which not only ensures the accuracy and speed of temperature detection, but also ensures that the temperature sensing element 40 will not interfere with the pot even when using a pointed bottom pot, thus expanding the applicability of the stove 1.

[0116] See also Figures 2 to 16 The burner head 30 includes a bracket 310 and an ejector tube 320. The bracket 310 is located within the mounting cavity 110, and the ejector tube 320 is positioned by the bracket 310. The temperature sensing element 40 is mounted on the bracket 310. The bracket 310 can be made of a thermally conductive material, such as metal or other materials with good heat transfer properties. The ejector tube 320 can also be made of a thermally conductive material, such as metal or other materials with good heat transfer properties. The bracket 310 and the ejector tube 320 can be made of the same material, such as stainless steel, thus forming a stainless steel assembly. Thus, at least a portion of the temperature sensing element 40 comes into contact with the bracket 310 of the positioning ejector tube 320. Since the temperature of the bracket 310 is related to the temperature of the bottom of the pot, the temperature of the bottom of the pot can be detected by sensing the temperature of the bracket 310 through the temperature sensing element 40 (i.e., indirectly detecting the temperature of the pot). The temperature sensing element 40 is not affected by the flame, which not only ensures the accuracy and speed of temperature detection, but also ensures that the temperature sensing element 40 will not interfere with the pot even when using a pointed bottom pot, thus expanding the applicability of the stove 1.

[0117] It should be understood that in this embodiment of the utility model, the temperature sensing element 40 actually detects the relevant temperature of the bottom of the pot indirectly by detecting the temperature of the bracket 310. In order to ensure the accuracy of temperature detection, the bracket 310 can be made of a material with good thermal conductivity, such as stainless steel.

[0118] See also Figures 2 to 12 At least a portion of the temperature sensing element 40 can form surface contact with the support 310. Thus, through this surface contact, since the temperature of the support 310 is related to the temperature of the pot bottom, the temperature sensing element 40 can detect the temperature of the pot bottom by sensing the temperature of the support 310 (i.e., indirectly detecting the temperature of the cookware). The temperature sensing element 40 is not affected by the flame, which not only ensures the accuracy and speed of temperature detection, but also ensures that the temperature sensing element 40 will not interfere with the cookware even when using a pointed-bottom pot, thus expanding the applicability of the stove 1.

[0119] See also Figure 2 , Figure 5 , Figure 6 , Figure 7 , Figure 8 and Figure 54 The bracket 310 may have a test surface 301. The temperature sensing element 40 may have a temperature sensing surface 410. The temperature sensing surface 410 may be in contact with the test surface 301. In this way, by the contact between the temperature sensing surface 410 and the test surface 301, surface contact is ensured between the temperature sensing element 40 and the bracket 310.

[0120] See again Figures 2 to 12 The support 310 may have a plate-shaped body 311 and a leg 312. One end of the leg 312 may be disposed on the plate-shaped body 311. The end of the leg 312 away from the plate-shaped body 311 may form a connecting end 3121. (See also...) Figure 1 When the burner head 30 is installed into the mounting cavity 110, the connecting end 3121 can be fixedly connected to the bottom shell 10 of the stove 1 to secure the burner head 30. The ejector tube 320 can at least partially penetrate the plate-shaped body 311. The surface to be measured 301 can be set on the plate-shaped body 311. This not only facilitates the positioning of the ejector tube 320, but also, since the temperature of the pot bottom above the burner head 30 is transferred to the plate-shaped body 311 through the ejector tube 320 when the pot is heated, the temperature of the plate-shaped body 311 is correlated with the temperature of the pot bottom, ensuring the accuracy and speed of temperature detection. Specifically, the plate-shaped body 311 can be made of a material with good thermal conductivity, such as stainless steel.

[0121] In some embodiments, the temperature sensing element 40 can be directly disposed on the plate-shaped body 311. In this way, the plate-shaped body 311 has a simple structure and is easy to process and manufacture.

[0122] For example, see Figure 5 The plate-shaped body 311 may have a first surface 3111, that is, the upper surface of the plate-shaped body 311. The surface to be measured 301 may be a part of the first surface 3111. That is, the surface contact location may be located on the first surface 3111 of the plate-shaped body 311. Understandably, the temperature sensing element 40 is entirely disposed above the plate-shaped body 311, that is, the temperature sensing element 40 is disposed on the side of the plate-shaped body 311 closer to the operator. This facilitates the installation of the temperature sensing element 40 and ensures that the temperature sensing element 40 forms surface contact with the support 310.

[0123] For example, see Figure 9The plate-shaped body 311 may have a second surface 3112, that is, the lower surface of the plate-shaped body 311. The surface to be measured 301 may be a part of the second surface 3112. That is, the surface contact location may be located on the second surface 3112 of the plate-shaped body 311. Understandably, the temperature sensing element 40 is entirely disposed below the plate-shaped body 311, that is, the temperature sensing element 40 is disposed on the side of the plate-shaped body 311 away from the pot. On the one hand, this avoids the influence of flame combustion on temperature detection, ensuring the accuracy of temperature detection; on the other hand, the temperature sensing element 40 is hidden below the plate-shaped body 311, effectively preventing leaked soup from contacting the temperature sensing element 40 and affecting the accuracy and service life of the temperature sensing element 40.

[0124] In some embodiments, in conjunction with reference Figure 6 , Figure 7 and Figure 8 The plate-shaped body 311 may have a first surface 3111 and a protrusion 3113. The protrusion 3113 may protrude from the first surface 3111. The surface to be measured 301 may be disposed on the protrusion 3113. In this way, the protrusion 3113 can position the temperature sensing element 40 for installation, facilitating the installation and fixation of the temperature sensing element 40. Furthermore, since the protrusion 3113 protrudes from the first surface 3111, it allows leaked soup to flow down easily, effectively preventing the leaked soup from soaking the temperature sensing element 40 and thus affecting the accuracy and service life of the temperature sensing element 40.

[0125] For example, see Figure 6 The protrusion 3113 may have a first outer surface 3113a. At least a portion of the first outer surface 3113a may be configured as the surface to be measured 301.

[0126] Furthermore, the protrusion 3113 may have a top wall 3113b and a connecting side wall 3113c. The top wall 3113b and the connecting side wall 3113c may enclose a receiving cavity 3114 with a lower opening 3116a. At least a portion of the inner wall surface of the receiving cavity 3114 may be configured as a test surface 301. In this way, on the one hand, the protrusion 3113 can position the installation of the temperature sensing element 40, which facilitates the installation and fixation of the temperature sensing element 40; on the other hand, the test surface 301 is set in the receiving cavity 3114, which not only makes it more conducive to the stable fixation of the temperature sensing element 40, but also effectively prevents leaked soup from contacting the test surface 301, thereby affecting the accuracy and service life of the temperature sensing element 40. At the same time, since the receiving cavity 3114 has a heat-concentrating effect, it further ensures the accuracy of the temperature sensing element 40.

[0127] For example, see Figure 7The temperature sensing element 40 may have a heat-conducting portion 420 and a lead portion 430 connected to the heat-conducting portion 420. The heat-conducting portion 420 may be placed inside the receiving cavity 3114. The lead portion 430 may extend outside the receiving cavity 3114 through the lower opening 3116a. In this way, the receiving cavity 3114 can position the heat-conducting portion 420 for installation, facilitating the installation and fixation of the temperature sensing element 40, and also facilitating the extension of the lead portion 430 outside the receiving cavity 3114. At the same time, since the receiving cavity 3114 has a heat-concentrating effect, it further ensures the accuracy of the temperature detection by the temperature sensing element 40. Understandably, the figure only shows the case where the heat-conducting portion 420 is in contact with the inner wall surface of the top wall 3113b. In an embodiment not shown, the heat-conducting part 420 may be in contact with the inner wall surface of the connecting side wall 3113c, or the heat-conducting part 420 may be in contact with both the inner wall surface of the connecting side wall 3113c and the inner wall surface of the top wall 3113b.

[0128] For example, see Figure 8 The temperature sensing element 40 may have a heat-conducting portion 420 and a lead portion 430 connected to the heat-conducting portion 420. A side opening 3116c may be provided on the connecting side wall 3113c. The heat-conducting portion 420 may be placed in the receiving cavity 3114 through the side opening 3116c. The lead portion 430 may extend out of the receiving cavity 3114 through the side opening 3116c and be located above the heat-conducting portion 420. Thus, the side opening 3116c can be used to position the heat-conducting part 420 for installation. Simply align the heat-conducting part 420 with the side opening 3116c, and then insert the heat-conducting part 420 into the receiving cavity 3114 through the side opening 3116c to complete the installation of the temperature sensing element 40. This facilitates the installation and fixation of the temperature sensing element 40. Furthermore, placing the heat-conducting part 420 within the receiving cavity 3114 effectively prevents leaked liquid from contacting the heat-conducting part 420, thereby avoiding any impact on the accuracy and service life of the temperature sensing element 40.

[0129] Specifically, the temperature-sensing surface 410 may have a third area S3. The inner wall surface of the accommodating cavity 3114 may have a fourth area S4. S4 / S3 = 1 to 1.5, for example, S4 / S3 can be 1, 1.2, 1.5, etc. Understandably, the third area S3 of the temperature-sensing surface 410 is the area where the heat-conducting part 420 is in contact with the inner wall surface of the accommodating cavity 3114. The fourth area S4 of the inner wall surface of the accommodating cavity 3114 is the area of ​​the cavity wall where the heat-conducting part 420 is in contact with it. When the heat-conducting part 420 is provided on the connecting side wall 3113c, the fourth area S4 is the area of ​​the inner wall surface of the connecting side wall 3113c; when the heat-conducting part 420 is provided on the top wall 3113b, the fourth area S4 is the area of ​​the inner wall surface of the top wall 3113b. When the third area S3 and the fourth area S4 have this relationship, the heat-conducting part 420 can be completely embedded in the receiving cavity 3114, ensuring that the heat-conducting part 420 can completely fit the inner wall surface, ensuring the accuracy of temperature detection. At the same time, the receiving cavity 3114 can also play a positioning role for the heat-conducting part 420 during installation. In some embodiments, S4 / S3 = 1.2, in which case the fitting and fixing effect between the heat-conducting part 420 and the receiving cavity 3114 is even better.

[0130] In some embodiments, see Figure 10 , Figure 11 and Figure 12 The plate-shaped body 311 may have a second surface 3112 and a recessed groove 3115. The recessed groove 3115 may be recessed below the second surface 3112. The surface to be measured 301 is disposed on the recessed groove 3115. In this way, the recessed groove 3115 can position the temperature sensing element 40 for installation and facilitates the installation and fixation of the temperature sensing element 40.

[0131] For example, see Figure 10 The recess 3115 may have a second outer surface 3115a. At least a portion of the second outer surface 3115a is configured as the surface to be measured 301. In this way, the recess 3115 can position the temperature sensing element 40 for installation, facilitating the installation and fixation of the temperature sensing element 40.

[0132] Furthermore, the recessed groove 3115 may have a bottom wall 3115c and a side wall 3115b. The bottom wall 3115c and the side wall 3115b can be closed to form the recessed groove 3115. At least a portion of the inner wall surface of the recessed groove 3115 is configured as the surface to be measured 301. In this way, the recessed groove 3115 can be used to position the temperature sensing element 40 for installation, and facilitates the installation and fixation of the temperature sensing element 40. At the same time, since the recessed groove 3115 has a heat-concentrating effect, it further ensures the accuracy of the temperature detection by the temperature sensing element 40.

[0133] For example, see Figure 11The temperature sensing element 40 may have a heat-conducting portion 420 and a lead portion 430 connected to the heat-conducting portion 420. The recessed groove 3115 may have an upper opening 3116b. The heat-conducting portion 420 can be placed inside the recessed groove 3115 through the upper opening 3116b. The lead portion 430 can extend outside the recessed groove 3115 through the upper opening 3116b. In this way, the recessed groove 3115 can position the installation of the heat-conducting portion 420 and facilitate the extension of the lead portion 430 out of the recessed groove 3115. At the same time, since the recessed groove 3115 has a heat-concentrating effect, it further ensures the accuracy of the temperature sensing element 40. Understandably, the figure only shows the case where the heat-conducting portion 420 is in contact with the inner wall surface of the bottom wall 3115c of the groove. In an embodiment not shown, the heat-conducting part 420 may be in contact with the inner wall surface of the sidewall 3115b of the tank, or the heat-conducting part 420 may be in contact with both the inner wall surface of the sidewall 3115b of the tank and the inner wall surface of the bottom wall 3115c of the tank.

[0134] For example, see Figure 12 The temperature sensing element 40 may have a heat-conducting portion 420 and a lead portion 430 connected to the heat-conducting portion 420. A side opening 3116c may be provided on the groove sidewall 3115b of the recessed groove 3115. The heat-conducting portion 420 may be placed inside the recessed groove 3115 through the side opening 3116c. The lead portion 430 may extend out of the recessed groove 3115 through the side opening 3116c. Thus, the side opening 3116c can be used to position the heat-conducting part 420 for installation. Simply align the heat-conducting part 420 with the side opening 3116c, and then insert the heat-conducting part 420 into the recessed groove 3115 through the side opening 3116c to complete the installation of the temperature sensing element 40. This facilitates the installation and fixation of the temperature sensing element 40, and places the lead wire part 430 below the plate-shaped body 311, effectively preventing leaked soup from contacting the lead wire part 430 and thus affecting the accuracy and service life of the temperature sensing element 40.

[0135] Specifically, the temperature-sensing surface 410 may have a third area S3. The inner wall surface of the recessed groove 3115 may have a fifth area S5. S5 / S3 = 1 to 1.5, for example, S5 / S3 can be 1, 1.2, 1.5, etc. Understandably, the third area S3 of the temperature-sensing surface 410 is the area where the heat-conducting part 420 and the inner wall surface of the recessed groove 3115 are in contact. The fifth area S5 of the inner wall surface of the recessed groove 3115 is the area of ​​the groove wall where the heat-conducting part 420 is in contact. When the heat-conducting part 420 is provided on the side wall 3115b of the groove, the fifth area S5 is the area of ​​the inner wall surface of the side wall 3115b of the groove; when the heat-conducting part 420 is provided on the bottom wall 3115c of the groove, the area S3 is the area of ​​the inner wall surface of the bottom wall 3115c of the groove. When the third area S3 and the fifth area S5 have this relationship, the heat-conducting part 420 can be completely embedded in the recessed groove 3115, ensuring that the heat-conducting part 420 can completely fit the inner wall of the groove, thus ensuring the accuracy of temperature detection. At the same time, the recessed groove 3115 can also position the heat-conducting part 420 during installation. In some embodiments, S5 / S3 = 1.2, in which case the fitting and fixing effect between the heat-conducting part 420 and the recessed groove 3115 is even better.

[0136] See also Figure 37 and Figure 38 The support foot 312 may have a test surface 301. The heat-conducting part 420 may have a temperature-sensing surface 410. The temperature-sensing surface 410 may be in contact with the test surface 301.

[0137] Specifically, in the length direction of the support 310 (i.e. Figure 19 In the X direction (as shown in the figure), the legs 312 can be bent from the left and right sides of the plate-shaped body 311, respectively. The surface to be measured 301 can be located on one of the left or right legs 312 of the plate-shaped body 311. The surface to be measured 301 can be a portion of the inner side of the leg 312 near the plate-shaped body 311 or the outer side away from the plate-shaped body 311. In an embodiment not shown, in the width direction of the bracket 310 (i.e., Figure 19 In the Y direction, the support legs 312 can be formed by bending from the front and rear sides of the plate-shaped body 311, respectively. The test surface 301 can be located on one of the support legs 312 on the front or rear side of the plate-shaped body 311. The test surface 301 can be a part of the inner side of the support leg 312 near the plate-shaped body 311 or a part of the outer side away from the plate-shaped body 311. In addition, protrusions 3113 or recesses 3115 can also be formed on the support legs 312 to improve the fit and fixation effect between the heat-conducting part 420 and the support legs 312.

[0138] See also Figures 13 to 16The temperature sensing element 40 can be connected to the bracket 310 via a fixing structure. Thus, the temperature sensing element 40 is connected to the bracket 310 via the fixing structure, and at least a portion of the temperature sensing element 40 is in contact with the bracket 310 of the positioning ejector tube 320. This facilitates the installation of the temperature sensing element 40; furthermore, since the temperature of the bracket 310 is related to the temperature of the pot bottom, the temperature of the pot bottom can be detected by sensing the temperature of the bracket 310 through the temperature sensing element 40 (i.e., indirectly detecting the pot temperature). The temperature sensing element 40 is not affected by the flame, ensuring not only the accuracy and speed of temperature detection, but also that even when using a pointed-bottom pot, the temperature sensing element 40 will not interfere with the pot, expanding the applicability of the stove 1.

[0139] See also Figure 14 , Figure 15 , Figure 16 and Figure 54 The temperature sensing element 40 may have a heat-conducting part 420. The heat-conducting part 420 can form a surface contact with a part of the bracket 310 through a fixing structure. In this way, it is easy for the temperature sensing element 40 to form a surface contact with the bracket 310, ensuring the accuracy and speed of temperature detection. Moreover, based on the setting of the heat-conducting part 420 and the fixing structure, it is easier to install the temperature sensing element 40.

[0140] The heat-conducting part 420 is in contact with a portion of the fixed structure. In this way, the heat-conducting part 420 can indirectly sense the temperature of the bracket 310 through the fixed structure, ensuring the accuracy and speed of temperature detection; thus, the temperature sensing element 40 can be applied in more scenarios.

[0141] In some embodiments, in conjunction with reference Figure 13 , Figure 14 and Figure 54 A through hole 423 may be provided on the heat-conducting part 420. The fixing structure may be constructed as a fastener 331. The fastener 331 may have a rod portion 3311. A portion of the rod portion 3311 may pass through the through hole 423 and connect to the plate-shaped body 311. In this way, it is convenient to position and install the temperature sensing element 40, ensures the stability of the connection between the heat-conducting part 420 and the plate-shaped body 311, and ensures good surface contact.

[0142] For example, see Figure 5 and Figure 14 When the surface contact position is located on the first surface 3111 of the plate-shaped body 311, the temperature sensing element 40 can be integrally mounted above the plate-shaped body 311 by fastener 331. This facilitates the installation of the temperature sensing element 40 and ensures that the heat-conducting part 420 forms a surface contact with a part of the bracket 310.

[0143] For example, see Figure 9When the contact point is located on the second surface 3112 of the plate-shaped body 311, the temperature sensing element 40 can be integrally mounted below the plate-shaped body 311 via fasteners 331. On the one hand, this avoids the influence of flame combustion on temperature detection, ensuring the accuracy of temperature detection; on the other hand, the temperature sensing element 40 is hidden below the plate-shaped body 311, effectively preventing leaked soup or liquid from contacting the temperature sensing element 40 and affecting its detection accuracy and service life.

[0144] Specifically, the portion of the rod 3311 that protrudes from the through hole 423 can be threadedly connected to the plate-shaped body 311. This ensures the stability of the connection between the rod 3311 and the plate-shaped body 311.

[0145] Furthermore, a mating hole 3117 may be provided on the plate-shaped body 311. The rod portion 3311 can pass through the through hole 423 and the mating hole 3117 in sequence to connect the heat-conducting part 420 to the plate-shaped body 311, and the part of the rod portion 3311 that passes through the through hole 423 is threadedly connected to the plate-shaped body 311 to complete the locking.

[0146] See also Figure 14 and Figure 17 The rod portion 3311 can have a diameter D, where 1mm ≤ D ≤ 6mm. For example, the diameter D can be 1mm, 3.2mm, 6mm, etc. Setting the diameter within this range ensures the structural strength of the rod portion 3311 while avoiding the problem of poor heat conduction in the heat-conducting part 420 due to an excessively large diameter. In one embodiment of this utility model, the diameter D is 4mm. At this time, the structural strength of the rod portion 3311 is effectively ensured, while avoiding the problem of poor heat conduction in the heat-conducting part 420 due to an excessively large diameter.

[0147] See also Figure 14 and Figure 17 The rod portion 3311 can have a length L4, where 4mm ≤ L4 ≤ 8mm. For example, the length L4 can be 4mm, 5.6mm, 8mm, etc. Setting the length L4 within this range ensures the stability of the connection between the rod portion 3311 and the plate-shaped body 311. In one embodiment of this utility model, the length L4 is 6mm, which effectively ensures the stability of the connection between the rod portion 3311 and the plate-shaped body 311.

[0148] See also Figure 14 and Figure 17The fastener 331 may have a head 3312. The head 3312 may be connected to one end of the rod portion 3311. The cross-sectional area of ​​the head 3312 may be larger than the cross-sectional area of ​​the rod portion 3311. A heat insulation member 340 may be provided between the head 3312 and the heat-conducting portion 420. In this way, the head 3312 can abut against the heat-conducting portion 420, so that the heat-conducting portion 420 and the plate-shaped body 311 are in close contact. By providing a heat insulation member 340 between the head 3312 and the heat-conducting portion 420, the influence of the fastener 331 on the heat conduction of the heat-conducting portion 420 is reduced, ensuring the accuracy of temperature detection. Of course, the heat insulation member 340 may also be provided at other positions between the fastener 331 and the heat-conducting portion 420, or between the heat-conducting portion 420 and the plate-shaped body 311, to better reduce the influence of the fastener 331 on the heat conduction of the heat-conducting portion 420. Specifically, the heat insulation member 340 may be made of a heat-insulating material, such as silicone. In some embodiments, a heat-insulating coating may be applied between the head 3312 and the heat-conducting part 420 to reduce the influence of the fastener 331 on the heat conduction of the heat-conducting part 420.

[0149] In an embodiment not shown, a notch may be provided on the heat-conducting part 420. The fixing structure may have a rod part 3311. A portion of the rod part 3311 may pass through the notch and connect to the plate-shaped body 311. This facilitates the positioning and installation of the temperature sensing element 40 and simplifies the structure.

[0150] Specifically, the fixing structure may have a head 3312. The head 3312 may be connected to one end of the rod 3311. The cross-sectional area of ​​the head 3312 may be larger than the cross-sectional area of ​​the rod 3311. A heat insulation member 340 may be provided between the head 3312 and the heat-conducting part 420. In this way, the head 3312 can abut against the heat-conducting part 420, so that the heat-conducting part 420 and the plate-shaped body 311 are in close contact, and by providing a heat insulation member 340 between the head 3312 and the heat-conducting part 420, the influence of the fixing structure on the heat conduction of the heat-conducting part 420 is reduced, ensuring the accuracy of temperature detection.

[0151] Furthermore, a mating hole 3117 may be provided on the plate-shaped body 311. The rod portion 3311 can pass through the notch and the mating hole 3117 in sequence to connect the heat-conducting part 420 to the plate-shaped body 311, and the part of the rod portion 3311 that passes through the through hole 423 is threadedly connected to the plate-shaped body 311 to complete the locking.

[0152] In some embodiments, the fastener 331 is provided with a receiving hole (not shown in the figure). It should be understood that in order to be disposed in the receiving hole, the heat-conducting part 420 needs to be adapted to the receiving hole. For example, when the cross-section of the receiving hole is circular, the heat-conducting part 420 can be a columnar body, and the cross-sectional area of ​​the columnar body cannot exceed the cross-sectional area of ​​the receiving hole. The heat-conducting part 420 is disposed in the receiving hole. In this way, the heat generated by the ejector tube 320 can be transferred to the fastener 331 through the bracket 310, and the temperature sensing element 40 in contact with the fastener 331 can determine the temperature of the ejector tube 320 by sensing the temperature of the fastener. Therefore, while ensuring that the temperature sensing element 40 can sense the temperature of the ejector tube 320, the connection structure of the burner head 30 can also be effectively simplified, and the manufacturing difficulty and manufacturing cost of the burner head 30 can be reduced. In an embodiment not shown, the fastener 331 is a screw or bolt having a shank 3311, and the heat-conducting part 420 can be a sleeve-like body, with the heat-conducting part 420 sleeved on the shank 3311 of the fastener 331. In an embodiment not shown, the fastener 331 is a screw or bolt having a head 3312, and the heat-conducting part 420 can be a sheet-like body, with the sheet-like heat-conducting part 420 fitting against the head 3312 of the fastener 331.

[0153] Furthermore, the head 3312 of the fastener 331 may be provided with a receiving hole, in which the heat-conducting part 420 can be placed to sense the temperature of the fastener 331. This eliminates the need to open a through hole 423 on the heat-conducting part 420, reducing the manufacturing difficulty of the temperature sensing element 40 and avoiding the situation where the heat-conducting part 420 has poor heat conduction due to the excessive area of ​​the through hole 423.

[0154] For example, when the surface contact location is on the first surface 3111 of the plate-shaped body 311, the temperature sensing element 40 can be integrally mounted above the plate-shaped body 311 by a fixing structure. This facilitates the installation of the temperature sensing element 40 and ensures that the heat-conducting part 420 forms surface contact with a part of the bracket 310.

[0155] For example, when the surface contact position is located on the second surface 3112 of the plate-shaped body 311, the temperature sensing element 40 is integrally disposed below the plate-shaped body 311 by a fixing structure. On the one hand, this avoids the influence of flame combustion on temperature detection, ensuring the accuracy of temperature detection; on the other hand, the temperature sensing element 40 is hidden below the plate-shaped body 311, effectively preventing leaked soup or water from contacting the temperature sensing element 40 and affecting the accuracy and service life of the temperature sensing element 40.

[0156] In some embodiments, see Figure 15The fixing structure can be constructed as a locking structure 332. The locking structure 332 may include a locking part 3321 and a locking hole 3322. In this way, the plate-shaped body 311 and the heat-conducting part 420 are connected by the locking structure 332, which ensures the stability of the connection and ensures that a surface contact is formed between the plate-shaped body 311 and the heat-conducting part 420.

[0157] For example, see Figure 15 The locking hole 3322 can be provided on the plate-shaped body 311. The locking part 3321 can extend from the side of the heat-conducting part 420, and after passing through the locking hole 3322, the locking part 3321 can be bent to abut against the plate-shaped body 311. The surface contact position can be located on the second surface 3112 of the plate-shaped body 311. Understandably, the temperature sensing element 40 is integrally disposed below the plate-shaped body 311 by means of the locking structure 332, that is, the temperature sensing element 40 is disposed on the side of the plate-shaped body 311 away from the pot.

[0158] For example, the latching hole 3322 can be provided on the plate-shaped body 311. The latching portion 3321 can extend from the side of the heat-conducting portion 420, and after passing through the latching hole 3322, the latching portion 3321 can be bent to abut against the plate-shaped body 311. The surface contact position can be located on the second surface 3112 of the plate-shaped body 311. Understandably, the temperature sensing element 40 is integrally disposed below the plate-shaped body 311 by means of the latching structure 332, that is, the temperature sensing element 40 is disposed on the side of the plate-shaped body 311 away from the cookware.

[0159] For example, the latching hole 3322 can be provided on the heat-conducting part 420. The latching part 3321 can extend from the plate-shaped body 311, and after passing through the latching hole 3322, the latching part 3321 can be bent to abut against the heat-conducting part 420. The surface contact position can be located on the second surface 3112 of the plate-shaped body 311. Understandably, the temperature sensing element 40 is integrally disposed below the plate-shaped body 311 by means of the latching structure 332, that is, the temperature sensing element 40 is disposed on the side of the plate-shaped body 311 away from the pot.

[0160] For example, the latching hole 3322 can be provided on the heat-conducting part 420. The latching part 3321 can extend from the plate-shaped body 311, and after passing through the latching hole 3322, the latching part 3321 can be bent to abut against the heat-conducting part 420. The surface contact position can be located on the second surface 3112 of the plate-shaped body 311. Understandably, the temperature sensing element 40 is integrally disposed below the plate-shaped body 311 by means of the latching structure 332, that is, the temperature sensing element 40 is disposed on the side of the plate-shaped body 311 away from the pot.

[0161] In some embodiments, the fixing structure may have all three structures or two of the three structures mentioned above. That is, the temperature sensing element 40 may be connected to the bracket 310 by fastener 331 cooperating with the through hole 423, rod 3311 and head 3312 cooperating with the notch, and locking structure 332; or, the temperature sensing element 40 may be connected to the bracket 310 by fastener 331 cooperating with the through hole 423, rod 3311 and head 3312 cooperating with the notch, and locking structure 332.

[0162] For example, see Figure 16 The temperature sensing element 40 can be connected to the bracket 310 simultaneously via two connection methods: fastener 331 engaging with the through hole 423 and snap-fit ​​structure 332. In embodiments not shown, the temperature sensing element 40 can also be connected to the heat-conducting element 350 by other methods, such as welding, riveting, bonding, or snap-fit ​​connection. This better ensures surface contact between the plate-shaped body 311 and the heat-conducting part 420, and further guarantees the stability of the connection.

[0163] It should be noted that the location of the surface contact is positioned with respect to the center of the temperature-sensing surface 410. When a through hole 423 is provided on the heat-conducting part 420, the center of the temperature-sensing surface 410 is the center of the through hole 423. In some embodiments, the through hole 423 and the mating hole 3117 can be concentric, so the axis of the fastener 331 can also be concentric with the through hole 423 and the mating hole 3117. In this case, the location of the surface contact can be the position of the axis of the fastener 331.

[0164] See also Figure 18 and Figure 43 The ejector tube 320 may include an inner ring ejector tube 321 and an outer ring ejector tube 322. Both the inner ring ejector tube 321 and the outer ring ejector tube 322 can be positioned by the bracket 310, and the inner ring ejector tube 321 and the outer ring ejector tube 322 can be spaced apart in a first direction. At least a portion of the temperature sensing element 40 can form surface contact with the bracket 310. The surface contact location can be between the inner ring ejector tube 321 and the outer ring ejector tube 322. The first direction can be the length direction of the bracket 310 (i.e., the direction of its length). Figure 19(in the X direction). It should be understood that the ejector tube 320 can be made of a heat-conducting material. The inner ring ejector tube 321 and the outer ring ejector tube 322 can also be made of a heat-conducting material, such as metal or other materials with good heat transfer properties. In this way, at least a portion of the temperature sensing element 40 forms surface contact with the bracket 310 that positions the inner ring ejector tube 321 and the outer ring ejector tube 322. Since the temperature of the bracket 310 is related to the temperature of the bottom of the pot, the temperature of the bottom of the pot can be detected by sensing the temperature of the bracket 310 through the temperature sensing element 40 (i.e., indirect detection of the pot temperature). The temperature sensing element 40 is not affected by the flame, which not only ensures the accuracy and speed of temperature detection, but also ensures that the temperature sensing element 40 will not interfere with the pot even when using a pointed-bottom pot, thus expanding the applicability of the stove 1.

[0165] See also Figure 28 and Figure 43 In the first direction, the location of the surface contact tube 321 can have a first lateral distance X1 from the center of the inner ring ejector tube 321. The location of the surface contact tube 322 can have a second lateral distance X2 from the center of the outer ring ejector tube 322, where 0.5X2≤X1≤X2. For example, the relationship between the first lateral distance X1 and the second lateral distance X2 can be 0.5X2=X2, 0.8X2=X2, X2=X2, etc. When the first lateral distance X1 and the second lateral distance X2 have this relationship, the accuracy and speed of temperature detection are effectively guaranteed. In one embodiment of this utility model, 0.8X2=X1, which further guarantees the accuracy and speed of temperature detection.

[0166] See again Figure 28 and Figure 43 In the width direction of bracket 310 (i.e. Figure 28 In the Y direction (as shown in the diagram), the position of the surface contact and the center of the inner ring ejector tube 321 can have a first longitudinal distance Y1, 0mm ≤ Y1 ≤ 10mm. For example, the first longitudinal distance Y1 can be 0mm, 4mm, 6mm, 10mm, etc. Within this range, the accuracy and speed of temperature detection are effectively guaranteed. In one embodiment of this utility model, the first longitudinal distance Y1 is 6mm, which well ensures the accuracy of the detection results of the temperature sensing element 40.

[0167] In an embodiment not shown, in the width direction of the bracket 310 (i.e. Figure 28 In the Y direction, the location of the surface contact can be located in front of or behind the center of the inner ring ejector tube 321.

[0168] See again Figure 28 and Figure 43 In the width direction of bracket 310 (i.e. Figure 28In the Y direction (as shown in the diagram), the position of the surface contact and the center of the outer ring ejector tube 322 can have a second longitudinal distance Y2, where 0mm ≤ Y2 ≤ 10mm. For example, the second longitudinal distance Y2 can be 0mm, 4mm, 6mm, 10mm, etc. Within this range, the accuracy and speed of temperature detection are effectively guaranteed. In one embodiment of this invention, the second longitudinal distance Y2 is 6mm, which well ensures the accuracy of the detection results of the temperature sensing element 40.

[0169] See also Figure 19 and Figure 20 In the width direction of bracket 310 (i.e. Figure 19 In the Y direction, the location of the surface contact can be located in front of or behind the center of the outer ring ejector tube 322.

[0170] See Figure 18 The inner ring ejector tube 321 may have an inner ring tip 3211. The position where the inner ring tip 3211 contacts the surface may have a fifth spacing Z5 in the second direction. The fifth spacing Z5 can be 10mm to 25mm, for example, 10mm, 15mm, 20mm, 25mm, etc. The second direction may be perpendicular to the first direction. Understandably, the second direction may be the height direction of the support 310 (i.e.,...). Figure 18 (in the Z direction). Within this range, the fifth spacing Z5 effectively ensures the accuracy and speed of temperature detection. In one embodiment of this invention, the fifth spacing Z5 is 20mm, which further guarantees the accuracy and speed of temperature detection.

[0171] See again Figure 18 The outer ring ejector tube 322 may have an outer ring tip 3221. The location where the outer ring tip 3221 contacts the surface may have a sixth spacing Z6 in the second direction. The sixth spacing Z6 can be 8mm to 15mm, for example, 8mm, 10mm, 12mm, 15mm, etc. The second direction may be perpendicular to the first direction. Understandably, the second direction may be the height direction of the support 310 (i.e.,...). Figure 18 (in the Z direction). The sixth spacing Z6 is within this range, effectively ensuring the accuracy and speed of temperature detection. In one embodiment of this utility model, the sixth spacing Z6 is 10mm, which further ensures the accuracy and speed of temperature detection.

[0172] See also Figures 19 to 22The stove 1 may also include a burner cap 60. The burner cap 60 may be made of metal. The ejector tube 320 may have a protruding tube section 323 extending beyond the support 310. The burner cap 60 may be fitted onto the protruding tube section 323, dividing the protruding tube section 323 into a heat transfer section 3231 and a heat conduction section 3232. A portion of the burner cap 60 may be fitted onto the heat transfer section 3231. Thus, based on the configuration of the heat transfer section 3231 and the heat conduction section 3232, when heating a pot, the heat from the bottom of the pot can be transferred to the heat transfer section 3231 via the burner cap 60, and then to the support 310 via the heat conduction section 3232. Since the temperature sensing element 40 is located on the support 310, the temperature of the bottom of the pot can be detected by sensing the temperature of the support 310 (i.e., indirectly detecting the temperature of the pot). The temperature sensing element 40 is not affected by the flame, and even when using a pointed-bottom pot, the temperature sensing element 40 will not interfere with the pot, thus expanding the applicability of the stove 1.

[0173] Specifically, the flame cap 60 may include an inner ring flame cap 610 and an outer ring flame cap 620. The inner ring flame cap 610 may be fitted onto the inner ring ejector tube 321. The outer ring flame cap 620 may be fitted onto the outer ring ejector tube 322. A protruding tube section 323 may be located on the inner ring ejector tube 321. The inner ring flame cap 610 may be fitted onto the protruding tube section 323, dividing the protruding tube section 323 into a heat transfer section 3231 and a heat conduction section 3232. A portion of the inner ring flame cap 610 may be fitted onto the heat transfer section 3231.

[0174] The outer surface of the heat transfer section 3231 can have a first area S1, and the outer surface of the heat conduction section 3232 can have a second area S2, where 0.8S1≤S2≤1.5S1. For example, 0.8S1=S2, 1.1S1=S2, 1.5S1=S2, etc. Based on the relationship between the first area S1 and the second area S2, the heat from the bottom of the pot can be fully transferred to the support 310 by the heat conduction section 3232, ensuring the accuracy and speed of temperature detection. In one embodiment of this utility model, the relationship between the first area S1 and the second area S2 is S1=S2, ensuring the accuracy and speed of temperature detection.

[0175] For example, the outer ring ejector tube 322 can also be positioned by the bracket 310, that is, the inner ring ejector tube 321 and the outer ring ejector tube 322 can be jointly inserted into the bracket 310.

[0176] For example, the outer ring ejector tube 322 can also be positioned by another bracket 310 different from the bracket 310, that is, the inner ring ejector tube 321 and the outer ring ejector tube 322 can be positioned by different components respectively.

[0177] See also Figures 19 to 22 The inner ring flame cap 610 may have a bottom end face 611. In the axial direction of the protruding pipe section 323 (i.e.... Figure 22 In the Z direction, the surface contact position and the bottom surface 611 can have a seventh distance Z7. The seventh distance Z7 can be 5mm to 20mm. For example, the seventh distance Z7 can be 5mm, 13mm, 20mm, etc. With the seventh distance Z7 set within this range, the heat from the bottom of the pot can be fully transferred to the support 310 by the heat-conducting section 3232, ensuring the accuracy of temperature detection. In one embodiment of this utility model, the seventh distance Z7 can be 11.2mm. In this case, the heat from the bottom of the pot can be transferred to the support 310 more fully by the heat-conducting section 3232, further ensuring the accuracy of temperature detection.

[0178] See also Figure 19 and Figure 20 In the length direction of the bracket 310 (i.e. Figure 19 , Figure 20 and Figure 22 In the X direction, the position of the surface contact can have a third lateral distance X3 between it and the center of the inner ring burner cap 610. It should be noted that since the inner ring burner cap 610 is fitted onto the inner ring ejector tube 321, the center of the inner ring burner cap 610 and the center of the inner ring ejector tube 321 can be on the same axis. The third lateral distance X3 between the surface contact position and the center of the inner ring burner cap 610 is equal to the first lateral distance X1 between the surface contact position and the center of the inner ring ejector tube 321. The third lateral distance X3 can be 12mm to 15mm. For example, the third lateral distance X3 can be 12mm, 14mm, 15mm, etc. With the third lateral distance X3 set within this range, the heat from the bottom of the pot can be fully transferred to the support 310 by the heat-conducting section 3232, ensuring the accuracy of temperature detection. In one embodiment of this utility model, the third lateral distance X3 can be 13.5mm. In this case, the heat from the bottom of the pot can be more fully transferred to the support 310 by the heat-conducting section 3232, which further ensures the accuracy of temperature detection.

[0179] See also Figure 19 and Figure 20 In the width direction of bracket 310 (i.e. Figure 19 and Figure 20The third longitudinal distance Y3 between the surface contact position and the center of the inner ring burner cap 610 (in the Y direction) can be 0mm ≤ Y3 ≤ 10mm. For example, the third longitudinal distance Y3 can be 0mm, 5mm, 10mm, etc. It should be noted that since the inner ring burner cap 610 is sleeved on the inner ring ejector tube 321, the center of the inner ring burner cap 610 and the center of the inner ring ejector tube 321 can be on the same axis. The third longitudinal distance Y3 between the surface contact position and the center of the inner ring burner cap 610 is equal to the first longitudinal distance Y1 between the surface contact position and the center of the inner ring ejector tube 321. With the third longitudinal distance Y3 set within this range, the heat from the bottom of the pot can be fully transferred to the support 310 by the heat-conducting section 3232, ensuring the accuracy of temperature detection. In one embodiment of this utility model, the third longitudinal distance Y3 can be 6mm. In this case, the heat from the bottom of the pot can be more fully transferred to the support 310 by the heat-conducting section 3232, further ensuring the accuracy of temperature detection.

[0180] For example, see Figure 20 In the width direction of bracket 310 (i.e. Figure 19 and Figure 20 In the Y direction, the surface contact position can be located in front of or behind the center of the inner ring flame cap 610, that is, the surface contact position mentioned above can be located in front of or behind the center of the inner ring ejector tube 321.

[0181] See Figure 22 In the axial direction of the protruding pipe section 323 (i.e. Figure 22 In the Z direction (as shown in the diagram), the heat transfer section 3231 can have a length L5. The length L5 can be 5mm to 12mm. For example, the length L5 can be 5mm, 7mm, 12mm, etc. Setting the length L5 within this range avoids the problem that most of the heat from the bottom of the pot is blocked by the inner ring burner cap 610 and cannot be fully transferred to the support 310, thus ensuring the accuracy of temperature detection. In one embodiment of this invention, the length L5 is 8mm. In this case, the problem that most of the heat from the bottom of the pot is blocked by the inner ring burner cap 610 and cannot be fully transferred to the support 310 is effectively avoided, ensuring the accuracy of temperature detection.

[0182] See again Figure 22 In the axial direction of the protruding pipe section 323 (i.e. Figure 22In the Z direction (as shown in the diagram), the heat-conducting section 3232 can have a length L6. The length L6 can be 5mm to 12mm. For example, the length L6 can be 5mm, 7mm, 12mm, etc. With the length L6 set within this range, the heat from the bottom of the pot can be fully transferred to the support 310 by the heat-conducting section 3232, ensuring the accuracy of temperature detection. In one embodiment of this invention, the length L6 is 8mm. In this case, the heat from the bottom of the pot can be transferred to the support 310 more fully by the heat-conducting section 3232, ensuring the accuracy of temperature detection.

[0183] See also Figure 23 and Figure 27 The burner head 30 includes an ejector tube 320, at least a portion of which is located within the mounting cavity 110. A temperature sensing element 40 is disposed on the ejector tube 320, and at least a portion of the temperature sensing element 40 is in contact with the ejector tube 320.

[0184] Specifically, the number and type of ejector tubes 320 can be determined according to the type of burner head 30. If the burner head 30 is a double-ring burner head 30, the ejector tubes 320 may include an inner ring ejector tube 321 and an outer ring ejector tube 322. If the burner head 30 is a triple-ring burner head 30, the ejector tubes 320 may include an inner ring ejector tube 321, a middle ring ejector tube 320, and an outer ring ejector tube 322. The temperature sensing element 40 may be attached to one or more of the ejector tubes 320, preferably to the inner ring ejector tube 321.

[0185] Specifically, one end of the ejector tube 320 can be connected to the gas supply line, and the other end of the ejector tube 320 can be installed on the bracket 310. The temperature sensing element 40 can be directly or indirectly attached to the ejector tube 320. In this way, when the burner head 30 is in the combustion state, the heat generated can be transferred to the ejector tube 320, so that the temperature sensing element 40 can sense the temperature of the ejector tube 320.

[0186] In this way, the temperature sensing element 40 can come into contact with the ejector tube 320. When heating the cookware, the temperature of the bottom of the cookware can be transferred to the ejector tube 320. By sensing the temperature of the ejector tube 320, the temperature of the bottom of the cookware can be indirectly detected. This not only avoids direct contact between the temperature sensing element 40 and the cookware, preventing interference between them, thus allowing the burner head 30 to be used with different types of cookware, but also avoids the temperature sensing element 40 being too close to the flame of the burner head 30, preventing the temperature sensing element 40 from being affected by the flame. This effectively ensures the accuracy of the sensing results of the temperature sensing element 40, thereby improving the reliability and safety of the stove 1.

[0187] In some embodiments, in conjunction with reference Figures 23 to 27The ejector tube 320 has a tube body and a positioning boss 3243. The positioning boss 3243 protrudes from the outer wall surface of the tube body, and the tube body is divided into an upper tube section 3241 and a lower tube section 3242 by the positioning boss 3243. The temperature sensing element 40 has a heat-conducting part 420, at least a portion of which is in contact with the upper tube section 3241, or at least a portion of which is in contact with the lower tube section 3242. In this way, the heat-conducting part 420 of the temperature sensing element 40 can be in contact with the upper tube section 3241 or the lower tube section 3242, thereby sensing the temperature change of the ejector tube 320 in real time. Therefore, it can not only avoid the direct contact between the heat-conducting part 420 and the pot, thus avoiding the situation where the accuracy of the sensing result is affected, but also determine the temperature change of the pot bottom by the temperature change of the ejector tube 320, effectively improving the accuracy of the sensing result of the temperature sensing element 40 and the safety of the burner 30.

[0188] Specifically, the positioning boss 3243 can be set on the bracket 310, and the tube body can be inserted into the bracket 310 through the positioning boss 3243. The positioning boss 3243 can position the installation position of the tube body, simplifying the installation steps of the ejector tube 320 and reducing the possibility of installation errors.

[0189] Furthermore, the heat-conducting part 420 can be plate-shaped. The plate-shaped heat-conducting part 420 can be closely fitted with the upper pipe section 3241 or the lower pipe section 3242, thereby quickly and efficiently transferring the heat of the upper pipe section 3241 or the lower pipe section 3242 to the temperature sensing element 40. This greatly reduces the loss and delay in the heat transfer process and ensures that the temperature sensing element 40 can obtain more accurate temperature information.

[0190] See again Figure 24 and Figure 25 The heat-conducting part 420 of the temperature sensing element 40 can contact the upper pipe section 3241 of the tube body. Because the upper pipe section 3241 is closer to the cookware, the heat generated by the cookware heated by the burner 30 is more easily transferred to the upper pipe section 3241. Therefore, the temperature information sensed by the temperature sensing element 40 is faster and more direct. (See again...) Figure 26 and Figure 27 The heat-conducting part 420 of the temperature sensing element 40 can also contact the lower pipe section 3242 of the tube body. The lower pipe section 3242 is farther away from the pot than the upper pipe section 3241. The temperature sensing element 40 in contact with the lower pipe section 3242 is less likely to be disturbed by the heat generated by the flame, so the temperature information sensed by the temperature sensing element 40 is more accurate.

[0191] In some embodiments, see Figure 24The upper pipe section 3241 has an inner pipe section 3241a and a sleeve section 3241b. The sleeve section 3241b is fitted over the inner pipe section 3241a. A temperature-sensing surface 410 is formed on the heat-conducting section 420, and the temperature-sensing surface 410 makes surface contact with the outer surface of the sleeve section 3241b. In this way, the temperature-sensing surface 410 of the heat-conducting section 420 can directly make surface contact with the outer surface of the sleeve section 3241b. While ensuring that the temperature-sensing element 40 can sense the temperature of the ejector tube 320, it also simplifies the connection between the temperature-sensing element 40 and the ejector tube 320. When it is necessary to repair or replace the temperature-sensing element 40, it can be easily disassembled and installed, effectively improving the convenience of operation for operators.

[0192] The shape of the heat-conducting part 420 can be adapted to the outer contour of the sleeve part 3241b. Specifically, the shape of the heat-conducting part 420 can be an arc-shaped plate, which not only allows for sufficient contact area between the heat-conducting part 420 and the sleeve part 3241b, but also ensures that the two fit tightly together. The temperature-sensing surface 410 can be formed on the side of the heat-conducting part 420 that is in contact with the outer surface of the sleeve part 3241b.

[0193] The temperature-sensing surface 410 of the heat-conducting part 420 and the outer surface of the sleeve part 3241b can be in contact by means of adhesive connection or snap-fit ​​connection. This application does not specifically limit the contact method between the temperature-sensing surface 410 of the heat-conducting part 420 and the outer surface of the sleeve part 3241b.

[0194] In some embodiments, see Figure 25 The upper pipe section 3241 has an inner pipe portion 3241a and a sleeve portion 3241b. The sleeve portion 3241b is fitted over the inner pipe portion 3241a, and a receiving groove 3241c is provided between the sleeve portion 3241b and the inner pipe portion 3241a. The heat-conducting portion 420 is disposed within the receiving groove 3241c. Thus, the heat-conducting portion 420 can be disposed within the receiving groove 3241c between the sleeve portion 3241b and the inner pipe portion 3241a. The sleeve portion 3241b can apply force to the heat-conducting portion 420, so that the heat-conducting portion 420 can be tightly fitted within the receiving groove 3241c, effectively ensuring the strong connection between the temperature sensing element 40 and the ejector tube 320. Furthermore, the receiving groove 3241c avoids increasing the outer diameter of the ejector tube 320, effectively ensuring the manufacturing cost of the ejector tube 320.

[0195] See again Figure 25 The outer wall of the inner tube 3241a can be recessed inward to form a receiving groove 3241c. The depth of the receiving groove 3241c can be adapted to the thickness of the heat-conducting part 420, and the shape of the receiving groove 3241c can be adapted to the shape of the heat-conducting part 420, so that the heat-conducting part 420 can be embedded in the receiving groove 3241c.

[0196] In an embodiment not shown, the inner wall of the sleeve portion 3241b may be recessed outward to form the aforementioned receiving groove 3241c.

[0197] In some embodiments, a temperature-sensing surface 410 is formed on the heat-conducting portion 420, and the temperature-sensing surface 410 forms surface contact with the inner surface of the sleeve portion 3241b; or / and, the temperature-sensing surface 410 forms surface contact with the outer surface of the inner tube portion 3241a. Thus, the temperature-sensing element 40 can flexibly sense the temperature of the sleeve portion 3241b or the temperature of the inner tube portion 3241a, thereby determining the temperature of the ejector tube 320, further improving the flexibility and applicability of the temperature-sensing element 40.

[0198] In an embodiment not shown, the temperature sensing surface 410 may form a surface contact with the outer surface of the sleeve portion 3241b, or it may form a surface contact with the inner surface of the inner tube portion 3241a.

[0199] In some embodiments, see Figure 26 and Figure 27 A temperature-sensing surface 410 is formed on the heat-conducting part 420, and the temperature-sensing surface 410 makes surface contact with the outer surface of the lower pipe section 3242. In this way, the temperature-sensing surface 410 of the heat-conducting part 420 can directly make surface contact with the outer surface of the lower pipe section 3242. While ensuring that the temperature-sensing element 40 can sense the temperature of the ejector tube 320, it also simplifies the connection between the temperature-sensing element 40 and the ejector tube 320. When it is necessary to repair or replace the temperature-sensing element 40, it can be easily disassembled and installed, effectively improving the convenience of operation for operators.

[0200] The shape of the heat-conducting part 420 can be adapted to the outer contour of the lower pipe section 3242. Specifically, the shape of the heat-conducting part 420 can be an arc-shaped plate, which not only allows for sufficient contact area between the heat-conducting part 420 and the lower pipe section 3242, but also ensures that the two are tightly fitted together. The temperature-sensing surface 410 can be formed on the side of the heat-conducting part 420 that is in contact with the outer surface of the lower pipe section 3242.

[0201] The temperature-sensing surface 410 of the heat-conducting part 420 and the outer surface of the lower pipe section 3242 can be in contact by means of adhesive connection or snap-fit ​​connection. This application does not specifically limit the contact method between the temperature-sensing surface 410 of the heat-conducting part 420 and the outer surface of the lower pipe section 3242.

[0202] In some embodiments, see Figure 26The lower pipe section 3242 includes a pipe body 3242a and an outer clamp 3242b. At least a portion of the heat-conducting part 420 abuts against the outer surface of the pipe body 3242a via the outer clamp 3242b. In this way, the outer clamp 3242b can apply force to the heat-conducting part 420, so that the heat-conducting part 420 can be tightly attached to the outer surface of the pipe body 3242a, avoiding the possibility of the two parts falling off, thereby effectively ensuring the firmness of the connection between the temperature sensing element 40 and the ejector tube 320.

[0203] Specifically, the outer clamp 3242b can be sleeved on the outside of the tube body 3242a and apply force to the tube body 3242a, or the outer clamp 3242b can be snapped into the tube body 3242a, thereby attaching the heat-conducting part 420 to the outer surface of the tube body 3242a.

[0204] In some embodiments, see Figure 27 A temperature-sensing surface 410 is formed on the heat-conducting part 420, and the temperature-sensing surface 410 makes surface contact with the outer surface of the tube body 3242a. In this way, the temperature-sensing surface 410 of the heat-conducting part 420 can directly make surface contact with the outer surface of the tube body 3242a. While ensuring that the temperature-sensing element 40 can sense the temperature of the ejector tube 320, it also simplifies the connection between the temperature-sensing element 40 and the ejector tube 320. When it is necessary to repair or replace the temperature-sensing element 40, it can be easily disassembled and installed, effectively improving the convenience of operation for operators.

[0205] The shape of the heat-conducting part 420 can be adapted to the outer contour of the tube body 3242a. Specifically, the shape of the heat-conducting part 420 can be an arc-shaped plate, which not only allows for sufficient contact area between the heat-conducting part 420 and the tube body 3242a, but also ensures that the two are tightly fitted together. The temperature-sensing surface 410 can be formed on the side of the heat-conducting part 420 that is in contact with the outer surface of the tube body 3242a.

[0206] The temperature-sensing surface 410 of the heat-conducting part 420 can be in contact with the outer surface of the tube body 3242a by means of adhesive connection or snap-fit ​​connection. This application does not specifically limit the contact method between the temperature-sensing surface 410 of the heat-conducting part 420 and the outer surface of the tube body 3242a.

[0207] In some embodiments, in conjunction with reference Figures 24 to 27The bracket 310 has a plate-shaped body 311, through which the ejector tube 320 passes. The heat-conducting part 420 includes a first part 421 and a second part 422 connected to each other. The second part 422 is connected to the sensing part 431 through the first part 421. The first part 421 is parallel to the plate-shaped body 311, and the second part 422 is perpendicular to the plate-shaped body 311. The temperature-sensing surface 410 is located on the second part 422. In this way, the first part 421 and the second part 422 can be arranged perpendicularly to each other, so that while the temperature-sensing surface 410 is in close contact with the ejector tube 320, a gap can also be formed between the sensing part 431 and the ejector tube 320, thereby protecting the sensing part 431 from the influence of the temperature of the ejector tube 320, effectively improving the accuracy of temperature sensing and service life of the temperature sensing element 40.

[0208] The first part 421 and the second part 422 can be detachably connected or integrally formed. The detachable connection can include plug-in connection or adhesive connection, etc., and this application does not make specific limitations in this regard.

[0209] The temperature sensed by the temperature-sensing surface 410 on the second part 422 can be transmitted to the sensing part 431 through the second part 422 and the first part 421 in sequence. The plate-shaped body 311 of the second part 422 and the plate-shaped body 311 of the first part 421 can be perpendicular to each other. In this way, when the second part 422 is in contact with the side wall of the ejector tube 320, the first part 421 can form a gap between the sensing part 431 and the side wall of the ejector tube 320 to avoid direct contact between the sensing part 431 and the ejector tube 320, thereby interfering with or damaging the temperature sensing element 40.

[0210] In some embodiments, in conjunction with reference Figures 24 to 27 A flame cap 60 is fitted onto the ejector tube 320. This can refer to an inner ring flame cap 610, which has a bottom surface 611. The second part 422 has a top surface 4221. The top surface 4221 and the bottom surface 611 have an eighth distance Z8 in a direction perpendicular to the plate-shaped body 311, with the eighth distance Z8 being 6mm to 12mm. The distance between the top surface 4221 and the bottom surface 611 of the second part 422 can be within the aforementioned range. This avoids the distance between the temperature sensing element 40 and the heat source being too large or too small, which could affect the accuracy of temperature sensing by the temperature sensing element 40, thus greatly improving the reliability of the burner head 30.

[0211] Specifically, the burner cap 60 can have multiple combustion holes, and when the burner head 30 is in a combustion state, the burner cap 60 can evenly disperse the flame generated by the burner head 30 into multiple small flames.

[0212] Specifically, the distance between the top surface 4221 and the bottom surface 611 of the second part 422 should not be too large or too small. When the distance between the two is too large, it can be understood that the gap between the heat-conducting part 420 and the heat source is large, thus affecting the accuracy of the temperature sensing element 40. When the distance between the two is too small, the temperature sensing element 40 is easily interfered with by the heat source, which leads to inaccurate sensing results from the temperature sensing element 40.

[0213] Specifically, the value of the eighth spacing Z8 ranges from 6 mm to 12 mm, for example, 6 mm, 8 mm, 10 mm, 12 mm, etc. Within this range, the eighth spacing Z8 can ensure that the temperature sensing element 40 can sense the temperature of the ejector tube 320 while avoiding the influence of the heat source temperature. In one embodiment of this utility model, the eighth spacing Z8 is 8 mm. With this distance value, the sensing effect of the temperature sensing element 40 is well guaranteed.

[0214] See also Figures 2 to 16 The burner head 30 may include an ejector tube 320 and a heat conductor 350. The ejector tube 320 may be connected to the heat conductor 350. At least a portion of the temperature sensing element 40 may form surface contact with the heat conductor 350.

[0215] It should be understood that in this embodiment of the invention, the temperature sensing element 40 indirectly detects the temperature of the pot bottom by detecting the temperature of the heat-conducting element 350. To ensure the accuracy of temperature detection, the heat-conducting element 350 can be made of a heat-conducting material, such as metal or other materials with good heat transfer properties.

[0216] Thus, at least a portion of the temperature sensing element 40 forms surface contact with the heat-conducting element 350 connected to the ejector tube 320. Since the temperature of the heat-conducting element 350 is related to the temperature of the bottom of the pot, the temperature of the bottom of the pot can be detected by sensing the temperature of the heat-conducting element 350 through the temperature sensing element 40 (i.e., indirectly detecting the temperature of the pot). The temperature sensing element 40 is not affected by the flame, which not only ensures the accuracy and speed of temperature detection, but also ensures that the temperature sensing element 40 will not interfere with the pot even when using a pointed-bottom pot, thus expanding the applicability of the stove 1.

[0217] See also Figure 28 , Figure 29 and Figure 36 The location of the surface contact can be within a 360° annular region (for ease of understanding). Figure 28 and Figure 29 The annular region 360 in the figure is the projection of the annular region 360 onto the upper surface of the heat-conducting component 350. Figure 29The annular region 360 is the projection of the annular region 360 onto the upper surface of the plate-shaped body 311. The outer contour of the ejector tube 320 can be constructed as the inner ring 361 of the annular region 360. The outer contour of the ejector tube 320 offset by a distance L can be constructed as the outer ring 362 of the annular region 360, where L ≤ 40 mm, for example, L can be 40 mm, 35 mm, 30 mm, etc. In the case where the ejector tube 320 includes an inner ring ejector tube 321 and an outer ring ejector tube 322, the outer contour of the outer ring ejector tube 322 can be constructed as the inner ring 361 of the annular region 360. The outer contour of the outer ring ejector tube 322 offset by a distance L can be constructed as the outer ring 362 of the annular region 360, where L ≤ 40 mm, for example, L can be 40 mm, 35 mm, 30 mm, etc. Thus, with L within this range, the accuracy and speed of temperature detection are further guaranteed.

[0218] See also Figure 28 and Figure 29 The cross-section of the ejector tube 320 (which can be the outer ring ejector tube 322) can be annular. The annular region 360 can be constructed as follows: with the center of the ejector tube 320 as the center, the inner ring 361 has a radius of R3 and the outer ring 362 has a radius of R4, where R3 > 1 / 2D1 and R3 < R4 ≤ 60mm. D1 can be the outer diameter of the ejector tube 320. When R3 and R4 have this relationship, it is convenient for the temperature sensing element 40 to form a surface contact with the heat conducting element 350, and since R3 and R4 are within this range, the accuracy and speed of temperature detection are effectively guaranteed.

[0219] In some embodiments not shown, the cross-section of the ejector tube 320 (i.e., the outer ring ejector tube 322) may also be racetrack-shaped, square, etc. Understandably, in this case, the annular region 360 may be constructed as: a racetrack-shaped ring or a square ring with the center of the ejector tube 320 as the geometric center, the inner ring 361 having a size larger than the outer contour of the cross-section of the ejector tube 320, the outer ring 362 having a size less than 60 mm, and the inner ring 361 having a size smaller than the outer ring 362.

[0220] Furthermore, the cross-section of the ejector tube 320 can also be other shapes, such as square or polygonal. In this case, the annular region can also be other shapes.

[0221] See also Figure 2 , Figure 4 and Figure 28The burner head 30 may also include a support 310 for positioning the ejector tube 320. The support 310 may have a plate-shaped body 311. The ejector tube 320 may pass through the plate-shaped body 311. The plate-shaped body 311 may form a heat-conducting element 350. The surface contact position may be located on the plate-shaped body 311. The plate-shaped body 311 may be connected to a support leg 312. In this way, not only is it convenient to position the ejector tube 320, but also, since the temperature of the pot bottom above the burner head 30 is transferred to the plate-shaped body 311 through the ejector tube 320 when the pot is heated, the temperature of the plate-shaped body 311 is correlated with the temperature of the pot bottom, ensuring the accuracy and speed of temperature detection. Understandably, when the heat-conducting element 350 is a plate-shaped body 311, it can have the aforementioned technical features and effects, which will not be repeated here.

[0222] In some embodiments not shown, the foot 312 may form a heat-conducting element 350. The surface contact location may be located on the foot 312. Specifically, the foot 312 may have a test surface 301. The temperature sensing element 40 may have a temperature sensing surface 410. The temperature sensing surface 410 may be in contact with the test surface 301.

[0223] In some embodiments, in conjunction with reference Figures 29 to 36 The heat-conducting element 350 and the support 310 can be constructed as two different structures. In this way, if the temperature sensing element 40 malfunctions, the heat-conducting element 350 can be removed from the ejector tube 320 to facilitate the inspection and maintenance of the temperature sensing element 40 on the heat-conducting element 350, without having to remove the entire furnace head 30, thus reducing maintenance costs.

[0224] Specifically, see Figure 29 The heat-conducting component 350 may have a sleeve portion 351. The ejector tube 320 may have a mating section 325. A through hole (not shown in the figure) may be provided on the sleeve portion 351. The sleeve portion 351 can be sleeved onto the mating section 325 through the through hole. At the same time, in order to ensure the stability of the connection, the sleeve portion 351 can also be connected to the mating section 325 by means of adhesive, welding, snap-fit, etc. In this way, it is convenient to install the heat-conducting component 350, and since the temperature of the pot bottom above the burner 30 is transferred to the sleeve portion 351 through the ejector tube 320 when the pot is heated, the temperature of the heat-conducting component 350 is correlated with the temperature of the pot bottom, ensuring the accuracy and speed of temperature detection.

[0225] Furthermore, in conjunction with reference Figures 29 to 36The outer edge 9421 of the sleeve portion 351 can extend into a plate-shaped portion 352. The plate-shaped portion 352 can have a surface to be measured 301. The temperature sensing element 40 can have a temperature sensing surface 410. The temperature sensing surface 410 can be in contact with the surface to be measured 301. In this way, it is convenient to install the temperature sensing element 40, and since the temperature of the pot bottom above the burner 30 is transferred to the plate-shaped portion 352 through the ejector tube 320 when the pot is heated, the temperature of the plate-shaped portion 352 is correlated with the temperature of the pot bottom, ensuring the accuracy and speed of temperature detection.

[0226] For example, see Figure 31 The heat-conducting element 350 can be disposed above the plate-shaped body 311. The surface to be measured 301 can be part of the upper surface of the plate-shaped portion 352. This facilitates the installation of the temperature-sensing element 40.

[0227] For example, see Figure 32 The heat-conducting element 350 can be disposed above the plate-shaped body 311. The surface to be measured 301 can be a part of the lower surface of the plate-shaped portion 352. Understandably, the temperature-sensing element 40 is disposed entirely below the heat-conducting element 350, that is, the temperature-sensing element 40 is disposed on the side of the heat-conducting element 350 away from the pot, effectively preventing leaked soup from contacting the temperature-sensing element 40 and affecting the accuracy and service life of the temperature-sensing element 40.

[0228] For example, see Figure 33 The heat-conducting element 350 can be disposed below the plate-shaped body 311. The surface to be measured 301 can be part of the upper surface of the plate-shaped portion 352. In this way, the plate-shaped body 311 can shield the heat-conducting element 350, effectively preventing leaked soup from contacting the temperature sensing element 40 and affecting the accuracy and service life of the temperature sensing element 40.

[0229] For example, see Figure 34 The heat-conducting element 350 can be disposed below the plate-shaped body 311. The surface to be measured 301 can be a part of the lower surface of the plate-shaped portion 352. In this way, the plate-shaped body 311 can shield the heat-conducting element 350, effectively preventing leaked soup from contacting the temperature sensing element 40 and affecting the accuracy and service life of the temperature sensing element 40.

[0230] In an embodiment not shown, the heat-conducting element 350 may have a protrusion 3113 extending beyond its upper surface. A temperature-sensing element 40 may be disposed on the protrusion 3113. Specifically, the protrusion 3113 may enclose a receiving cavity 3114 having a lower opening 3116a. At least a portion of the inner wall surface of the receiving cavity 3114 may be configured as the surface to be measured 301; or, at least a portion of the outer wall surface of the receiving cavity 3114 may be configured as the surface to be measured 301.

[0231] In an embodiment not shown, the heat-conducting element 350 may have a recessed groove 3115 recessed into the lower surface of the heat-conducting element 350. A temperature-sensing element 40 may be disposed on the recessed groove 3115. Specifically, at least a portion of the inner wall surface of the recessed groove 3115 may be configured as the surface to be measured 301; or, at least a portion of the outer wall surface of the recessed groove 3115 may be configured as the surface to be measured 301.

[0232] See also Figures 37 to 40 The cooktop 1 may also include a burner base 70 and a burner cap 60. The burner cap 60 and the burner base 70 together form a mixing chamber 80 for communication with the injector tube 320. The burner base 70 may also be made of metal to ensure heat transfer and high temperature resistance. The mixing chamber 80 can be used to fully mix air and the gas entering from the injector tube 320, thereby improving combustion efficiency. The burner base 70 may have a bottom surface 710. The temperature sensing element 40 may have a temperature sensing surface 410. The temperature sensing surface 410 may be located below the bottom surface 710.

[0233] Thus, a temperature sensing element 40 is provided for sensing the temperature of the ejector tube 320. The temperature sensing element 40 is located below the bottom surface 710. When the cookware is heated, the heat from the bottom of the cookware can be transferred to the ejector tube 320 through the burner cap 60 and the burner base 70. Therefore, by sensing the temperature of the ejector tube 320, the temperature of the bottom of the cookware can be detected (i.e., the temperature of the cookware can be indirectly detected). This not only prevents the temperature sensing element 40 from being affected by the flame and ensures the accuracy of temperature detection, but also avoids interference between the temperature sensing element 40 and the cookware. This expands the types of cookware that can be placed on the stove 1 and broadens the applicability of the stove 1.

[0234] Furthermore, the ignition base 70 may have an air inlet 720, through which the mixing chamber 80 and the ejector tube 320 can be connected. A connecting section 730 may extend from the air inlet 720 away from the mixing chamber 80, and the connecting section 730 may be fitted onto the ejector tube 320. The connecting section 730 and the ignition base 70 can be an integral structure, facilitating the manufacturing of the ignition base 70. Alternatively, the connecting section 730 and the ignition base 70 can be separate structures, for example, connected by snap-fit ​​or adhesive methods, to facilitate cleaning and maintenance of the connecting section 730. Specifically, the outer wall of the connecting section 730 may have a groove, into which the wall of the air inlet 720 is inserted, connecting the connecting section 730 to the ignition base 70. Understandably, the bottom surface 710 may be provided on the connecting section 730. In this way, the contact area between the ignition seat 70 and the ejector tube 320 is increased by the connecting section 730, which not only improves the heat transfer effect from the ignition seat 70 to the ejector tube 320, but also improves the stability of the connection between the ignition seat 70 and the ejector tube 320.

[0235] In a direction perpendicular to the mounting plane of the burner base 70, there can be a first distance Z1 between the bottom surface 710 and the temperature sensing surface 410. This first distance Z1 can be 1mm to 5mm, for example, 1mm, 2mm, 3mm, 5mm, etc. Within this range, the heat from the bottom of the cookware can be transferred to the injector tube 320 through the burner cap 60 and the burner base 70. Therefore, by sensing the temperature of the injector tube 320, the temperature of the bottom of the cookware can be detected (i.e., indirectly detecting the cookware temperature). This not only prevents the temperature sensing element 40 from being affected by the flame, ensuring accurate temperature detection, but also avoids interference between the temperature sensing element 40 and the cookware, thereby expanding the types of cookware that can be used on the stove 1 and broadening the applicability of the stove 1. In one embodiment of this invention, the first distance Z1 is 2mm, which effectively ensures the accuracy of the detection results from the temperature sensing element 40. Understandably, the mounting plane of the burner base 70 can be a horizontal plane.

[0236] See also Figures 41 to 43 The burner head 30 may include a bracket 310. The bracket 310 may have a first hole 313 and a sensing mounting position 315. The bracket 310 may be made of a thermally conductive material, such as metal or other materials with good heat transfer properties. The ejector tube 320 may have an inner ring ejector tube 321 passing through the first hole 313. The temperature sensing element 40 may be disposed at the sensing mounting position 315. Understandably, the sensing mounting position 315 can be the location where the temperature sensing element 40 is mounted on the bracket 310 and senses the temperature. The temperature sensing element 40 can directly or indirectly sense the temperature of the bracket 310 at the sensing mounting position 315. In direct sensing, the temperature sensing element 40 is in contact with the sensing mounting position 315, i.e., surface contact as mentioned above, to sense the temperature of the bracket 310; in indirect sensing, the temperature sensing element 40 is not in direct contact with the sensing mounting position 315, but rather in contact with the sensing mounting position 315 through a fixed structure, i.e., indirectly sensing the temperature of the bracket 310 by sensing the temperature of the fixed structure. Specifically, the first hole 313 can be used for the insertion of the ejector tube 320, which can be an inner ring ejector tube 321. In this way, not only can the inner ring ejector tube 321 be positioned by the bracket 310, but also the heat on the inner ring ejector tube 321 can be transferred to the bracket 310. Since the sensing mounting position 315 is set on the bracket 310, the temperature of the inner ring ejector tube 321 can be indirectly sensed by sensing the temperature of the bracket 310, thereby realizing the detection of the bottom temperature of the pot. This prevents the temperature sensing element 40 from being affected by the flame, ensures the accuracy of temperature detection, and avoids interference between the temperature sensing element 40 and the pot. This expands the types of pots that can be placed on the stove 1 and broadens the applicability of the stove 1.

[0237] See also Figure 41 and Figure 43The burner head 30 may also include a thermocouple 370. A second hole 314 may be provided on the bracket 310. The thermocouple 370 may pass through the second hole 314. The thermocouple 370 may be made of metal. During use, the inner ring flame will burn the thermocouple 370, causing it to transfer heat to the bracket 310. The center of the second hole 314 may be located on a first circle with radius R1 centered at the sensing mounting position 315, and the center of the second hole 314 may have a first distance L1 from the center of the first hole 313, where R1 > L1. That is, the thermocouple 370 is closer to the inner ring ejector tube 321 than the temperature sensing element 40. This not only ensures the normal operation of the thermocouple 370 but also prevents the thermocouple 370 from being too close to the sensing mounting position 315 of the temperature sensing element 40, thereby preventing the heat generated by the thermocouple 370 from being transferred to the sensing mounting position 315 and affecting the detection results of the temperature sensing element 40.

[0238] See also Figure 41 and Figure 43 The radius R1 can be 30mm to 45mm, for example, 30mm, 35mm, 40mm, 45mm, etc. Thus, within this range, the heat generated by the thermocouple 370 is further prevented from being transferred to the sensing mounting position 315 and affecting the detection result of the temperature sensing element 40. In one embodiment of this invention, the radius R1 is 35mm, which effectively ensures the accuracy of the detection result of the temperature sensing element 40.

[0239] See again Figure 41 and Figure 43 The first distance L1 can be 15mm to 18mm, for example, 15mm, 16.9mm, 17.5mm, 18mm, etc. Within this range, the first distance L1 ensures the normal operation of the thermocouple 370, allowing it to monitor the temperature of the combustion flame in the inner ring ejector tube 321 in real time, thus ensuring the efficient and safe operation of the stove 1. In one embodiment of this invention, the first distance L1 is 16.9mm, which effectively ensures the accuracy of the thermocouple 370 in monitoring the combustion flame temperature of the inner ring ejector tube 321.

[0240] See also Figure 42 and Figure 43The burner head 30 may also include an ignition needle 380. The bracket 310 may have a third hole 316 through which the ignition needle 380 passes. The bracket 310 supports and positions the ignition needle 380, and facilitates its installation on the bracket 310. The ignition needle 380 may be made of metal or ceramic. During use, the inner ring flame will heat the ignition needle 380, causing it to conduct heat to the bracket 310. The center of the third hole 316 may be located on a second circle with radius R2 centered at the sensing installation position 315, and the center of the third hole 316 may have a second distance L2 from the center of the first hole 313, where R2 > L2. That is, the ignition needle 380 is closer to the inner ring ejector tube 321 than the temperature sensing element 40. In this way, not only is the normal operation of the ignition needle 380 guaranteed, but the sensing mounting position 315 of the temperature sensing element 40 is also prevented from being too close to the ignition needle 380, thus preventing the heat generated by the ignition needle 380 from being transferred to the sensing mounting position 315 and affecting the detection results of the temperature sensing element 40.

[0241] See also Figure 42 and Figure 43 The radius R2 can be 30mm to 45mm, for example, 30mm, 35mm, 40mm, 45mm, etc. Thus, within this range, the heat generated by the ignition needle 380 is prevented from being transferred to the sensing mounting position 315, thus avoiding interference with the detection results of the temperature sensing element 40. In one embodiment of this invention, the radius R2 is 35mm, which effectively ensures the accuracy of the detection results from the temperature sensing element 40.

[0242] See again Figure 42 and Figure 43 The second distance L2 can be 5mm to 11mm, for example, 5mm, 5.7mm, 8mm, 11mm, etc. Within this range, the second distance L2 ensures the normal operation of the ignition needle 380, enabling it to accurately ignite the gas and ensuring the burner head 30 can start combustion. In one embodiment of this invention, the second distance L2 is 5.7mm, which effectively ensures the accurate ignition of the gas by the ignition needle 380.

[0243] See also Figure 43 The support 310 may also have a fourth hole 317. The ejector tube 320 may have an outer ring ejector tube 322 passing through the fourth hole 317. The first hole 313 and the fourth hole 317 may be located along the length of the support 310 (e.g., Figure 43The inner ring ejector tube 321 is spaced apart in the X-direction to facilitate centralized flame control and help the outer ring ejector tube 322 expand the combustion range. The sensing mounting position 315 can be located between the first hole 313 and the fourth hole 317. The temperature of both the inner ring ejector tube 321 and the outer ring ejector tube 322 can be evenly transmitted to the sensing mounting position 315, and other components are effectively prevented from interfering with the detection of the temperature sensing element 40. Thus, with the temperature sensing element 40 located between the inner ring ejector tube 321 and the outer ring ejector tube 322, the temperature sensing element 40 has a better effect on the temperature detection of the ejector tube 320.

[0244] See also Figure 44 and Figure 49 The cooktop 1 may also include a liquid collection tray 90, and the panel 20 may have a through hole 210. The liquid collection tray 90 can be supported on the panel 20 and cover the through hole 210. The liquid collection tray 90 and the panel 20 can be connected by adhesive, snap-fit, or other methods to ensure the stability of the connection between the liquid collection tray 90 and the panel 20. The liquid collection tray 90 can form a liquid collection cavity 910. The liquid collection tray 90 can be made of metal, which is not only easy to clean but also resistant to liquid corrosion. The temperature sensing element 40 can have a temperature sensing surface 410, which can be located below the liquid collection tray 90. In this way, the temperature sensing surface 410 is located below the liquid tray 90. The temperature of the bottom of the pot can be detected by sensing the temperature of the ejector tube 320 through the temperature sensing element 40 (that is, indirectly detecting the temperature of the pot). This not only prevents the temperature sensing element 40 from being affected by the flame and ensures the accuracy of temperature detection, but also avoids interference between the temperature sensing element 40 and the pot. This expands the types of pots that can be placed on the stove 1 and broadens the applicability of the stove 1.

[0245] See also Figures 44 to 46 The burner head 30 includes an ejector tube 320, and a through hole 920 can be provided on the liquid receiving tray 90. The ejector tube 320 can pass through the through hole 920. Understandably, a part of the ejector tube 320 can be placed outside the mounting cavity 110, and another part can be placed inside the mounting cavity 110. A leak-proof structure 930 can be provided at the through hole 920. The mounting cavity 110 can be isolated from the liquid receiving cavity 910 through the leak-proof structure 930. The temperature sensing element 40 can be located inside the mounting cavity 110. Thus, by providing the leak-proof structure 930, the liquid received in the liquid receiving cavity 910 can be effectively prevented from seeping into the mounting cavity 110 through the through hole 920, which not only avoids liquid entering the mounting cavity 110 and affecting the detection results of the temperature sensing element 40, but also reduces the possibility of safety risks.

[0246] In an embodiment not shown in the figure, a seal may be provided between the liquid tray 90 and the panel 20 to prevent liquid from flowing into the mounting cavity 110 from the through hole 210. The seal may be made of rubber, which has good resilience, is easy to process, and is inexpensive, thus saving processing costs. Of course, the seal may also be made of other materials, as long as the sealing performance is met.

[0247] For example, in a direction perpendicular to the panel 20, the liquid collection tray 90 may have a flange formed around the perforation 920. The flange may extend beyond the upper surface of the liquid collection tray 90. The flange may form at least a partial leak-proof structure 930. Thus, on the one hand, by blocking the liquid within the liquid collection cavity 910 through the flange, liquid can be effectively prevented from seeping into the mounting cavity 110 from the perforation 920, which not only avoids liquid entering the mounting cavity 110 and affecting the detection results of the temperature sensing element 40, but also reduces the possibility of safety risks; on the other hand, the flange can be achieved through processes such as stamping or bending, which has a low manufacturing cost, thereby saving manufacturing costs.

[0248] For example, an annular elastic ring can be provided between the outer wall of the ejector tube 320 and the wall of the through hole 920. The annular elastic ring can form at least a partial leak-proof structure 930. In this way, by sealing the outer wall of the ejector tube 320 and the wall of the through hole 920 with the annular elastic ring, liquid can be effectively prevented from seeping into the mounting cavity 110 from the through hole 920. This not only avoids liquid entering the mounting cavity 110 and affecting the detection results of the temperature sensing element 40, but also reduces the possibility of safety risks.

[0249] See also Figure 44 , Figure 45 and Figure 49 The liquid collection tray 90 may have a guide portion protruding in the direction away from the mounting cavity 110, and the through hole 920 may be located on the guide portion. When liquid drips onto the guide portion, it can be guided into the liquid collection cavity 910 through the guide portion, reducing the amount of liquid at the through hole 920, thereby preventing liquid from entering the mounting cavity 110 and affecting the detection results of the temperature sensing element 40. The guide portion includes, but is not limited to, a hemispherical protrusion, a protrusion with a bevel, etc., to ensure that the liquid can flow into the liquid collection cavity 910 along the surface of the guide portion.

[0250] See again Figure 44 and Figure 49In embodiments where the ejector tube 320 may include an inner ring ejector tube 321 and an outer ring ejector tube 322, the through hole 920 may include a first through hole 921 and a second through hole 922. The first through hole 921 may be closer to the center of the liquid tray 90 than the second through hole 922. The inner ring ejector tube 321 may be inserted through the first through hole 921. The outer ring ejector tube 322 may be inserted through the second through hole 922. Understandably, the inner ring ejector tube 321 can be closer to the center of the burner head 30 in the stove 1 than the outer ring ejector tube 322. The centrally located inner ring ejector tube 321 facilitates centralized flame control, while the outer ring ejector tube 322, being farther from the center of the burner head 30 than the inner ring ejector tube 321, helps to expand the combustion range. To ensure the integrity of the stove 1, the first through hole 921 on the liquid tray 90 for the inner ring ejector tube 321 can be closer to the center of the liquid tray 90 than the second through hole 922 for the outer ring ejector tube 322. The leak-proof structure 930 can include a first leak-proof structure 931 and a second leak-proof structure 932. The first leak-proof structure 931 can be located at the first through hole 921. The second leak-proof structure 932 can be located at the second through hole 922. Thus, the first leak-proof structure 931 prevents the liquid in the liquid-containing cavity 910 from seeping into the mounting cavity 110 through the first through hole 921, and the second leak-proof structure 932 prevents the liquid in the liquid-containing cavity 910 from seeping into the mounting cavity 110 through the second through hole 922. This not only prevents the liquid from entering the mounting cavity 110 and affecting the detection results of the temperature sensing element 40, but also reduces the possibility of safety risks.

[0251] See again Figure 44 and Figure 49In a direction perpendicular to the panel 20, the liquid-collecting tray 90 may have a first flange 9311 formed around the first through hole 921. The first flange 9311 may be higher than the upper surface of the liquid-collecting tray 90. The first flange 9311 may form a first leak-proof structure 931. Understandably, the first flange 9311 and the liquid-collecting tray 90 may be an integral structure. Thus, on the one hand, by blocking the liquid in the liquid-collecting cavity 910 through the first flange 9311, the liquid can be effectively prevented from seeping into the mounting cavity 110 from the first through hole 921, which not only avoids the liquid entering the mounting cavity 110 from affecting the detection results of the temperature sensing element 40, but also reduces the possibility of safety risks; on the other hand, the first flange 9311 can be made by processes such as stamping or bending, which has a low manufacturing cost, thereby saving manufacturing costs. Furthermore, the outer wall surface of the first flange 9311 can be inclined relative to the upper surface of the liquid tray 90, or the first flange 9311 can be arc-shaped, ensuring that the outer wall surface of the first flange 9311 can guide the liquid into the liquid tray 910, further effectively preventing the liquid from seeping into the mounting cavity 110 from the first through hole 921. This not only further avoids the liquid entering the mounting cavity 110 and affecting the detection results of the temperature sensing element 40, but also further reduces the possibility of safety risks.

[0252] See Figure 45 The first flange 9311 can have a height H, which can be 1mm to 4mm, for example, 1mm, 2.5mm, 3mm, 4mm, etc. When the height H is within this range, the first flange 9311 effectively blocks the liquid within the liquid-containing cavity 910, effectively preventing liquid from seeping into the mounting cavity 110 from the first through hole 921. This not only avoids liquid entering the mounting cavity 110 and affecting the detection results of the temperature sensing element 40, but also reduces the possibility of safety risks. In one embodiment of this utility model, the height H is 2.5mm, which effectively ensures the accuracy of the detection results of the temperature sensing element 40.

[0253] In an embodiment not shown in the figure, a first annular elastic ring can be provided between the outer wall of the inner ring ejector tube 321 and the wall of the first through hole 921. The first annular elastic ring can form a first leak-proof structure 931. The first annular elastic ring can be made of rubber, which has good resilience, is easy to process, and is inexpensive, saving processing costs. Of course, the first annular elastic ring can also be made of other materials, as long as the sealing performance is met. The shape of the first annular elastic ring can be similar to the shape of the first through hole 921 and the outer wall of the inner ring ejector tube 321 for better sealing. In this way, by sealing the outer wall of the inner ring ejector tube 321 and the wall of the first through hole 921 with the first annular elastic ring, liquid can be effectively prevented from seeping into the mounting cavity 110 from the first through hole 921. This not only avoids liquid entering the mounting cavity 110 and affecting the detection results of the temperature sensing element 40, but also reduces the possibility of safety risks.

[0254] For example, a first groove may be provided on the outer ring 362 of the first annular elastic ring. A portion of the liquid-holding tray 90 may be engaged in the first groove. Furthermore, a limiting section may extend outward from the outer ring 362 of the first annular elastic ring, supporting the surface of the liquid-holding tray 90. When the liquid-holding tray 90 has a certain thickness, a first groove may also be provided on the wall of the first through hole 921, and a groove mating portion may extend outward from the outer ring 362 of the first annular elastic ring, which can mate with the first groove. This not only facilitates installation and disassembly but also ensures that the first annular elastic ring can be stably fixed between the outer wall of the inner ring ejector tube 321 and the wall of the first through hole 921.

[0255] For example, a support 310 can be provided below the liquid collection tray 90. The inner ring ejector tube 321 and the outer ring ejector tube 322 can be positioned by the support 310. The outer ring 362 of the first annular elastic ring can extend outward to form a support portion. The support portion can have a first abutment end and a second abutment end. The first abutment end can abut against the upper surface of the support 310. The lower surface of the liquid collection tray 90 can abut against the second abutment end. In this way, the support portion is supported between the support 310 and the liquid collection tray 90, thereby ensuring that the first annular elastic ring can be stably fixed between the outer wall surface of the inner ring ejector tube 321 and the hole wall of the first through hole 921. In addition, the first annular elastic ring can also extend in a direction perpendicular to the panel 20 to be supported on the support 310, which can also ensure that the first annular elastic ring is stably fixed between the outer wall surface of the inner ring ejector tube 321 and the hole wall of the first through hole 921.

[0256] In an embodiment not shown in the figure, a second flange may be formed around the liquid collection tray 90 in a direction perpendicular to the panel 20, around the second through hole 922. The second flange may be higher than the upper surface of the liquid collection tray 90. The second flange may form a second leak-proof structure 932. Understandably, the second flange and the liquid collection tray 90 may be an integral structure. In this way, on the one hand, by blocking the liquid in the liquid collection cavity 910 through the second flange, the liquid can be prevented from seeping into the mounting cavity 110 from the second through hole 922, which not only avoids the liquid entering the mounting cavity 110 from affecting the detection results of the temperature sensing element 40, but also reduces the possibility of safety risks; on the other hand, the second flange can be realized by processes such as stamping or bending, which has a low manufacturing cost, thereby saving manufacturing costs. Furthermore, the outer wall of the second flange can be inclined relative to the upper surface of the liquid tray 90. The outer wall of the second flange can guide the liquid into the liquid cavity 910, further effectively preventing the liquid from seeping into the mounting cavity 110 from the second through hole 922, thereby further avoiding the liquid entering the mounting cavity 110 and affecting the detection results of the temperature sensing element 40.

[0257] For example, the second flange can have a height H, which can be 1mm to 4mm, such as 1mm, 2.5mm, 3mm, 4mm, etc. Understandably, the height range of the second flange can be the same as the height range of the first flange 9311. When the height H is within this range, it ensures that the second flange can effectively block the liquid within the liquid-containing cavity 910, effectively preventing liquid from seeping into the mounting cavity 110 from the second through hole 922. This not only avoids liquid entering the mounting cavity 110 and affecting the detection results of the temperature sensing element 40, but also reduces the possibility of safety risks. In one embodiment of this utility model, the height H is 2.5mm, which effectively ensures the accuracy of the detection results of the temperature sensing element 40.

[0258] See also Figures 44 to 46 A second annular elastic ring 9321 can be provided between the outer wall of the outer ring ejector tube 322 and the wall of the second through hole 922. The second annular elastic ring 9321 can form a second leak-proof structure 932. The material of the second annular elastic ring 9321 can be rubber, which has good resilience, is easy to process, and is inexpensive, saving processing costs. Of course, the second annular elastic ring 9321 can also be made of other materials, as long as the sealing performance is met. The shape of the second annular elastic ring 9321 can be similar to the shape of the second through hole 922 and the outer wall of the outer ring ejector tube 322 for better sealing. In this way, by sealing the space between the outer wall of the outer ring ejector tube 322 and the wall of the second through hole 922 through the second annular elastic ring 9321, liquid can be effectively prevented from seeping into the mounting cavity 110 from the second through hole 922. This not only avoids liquid entering the mounting cavity 110 and affecting the detection results of the temperature sensing element 40, but also reduces the possibility of safety risks.

[0259] In an embodiment not shown in the figure, a second groove may be provided on the outer ring 362 of the second annular elastic ring 9321. A portion of the liquid collection tray 90 can be engaged in the second groove. Furthermore, the outer ring 362 of the second annular elastic ring 9321 may also extend outwards to form a limiting section, which supports the surface of the liquid collection tray 90. When the liquid collection tray 90 has a certain thickness, the wall of the second through hole 922 may also be provided with a second groove, and the outer ring 362 of the second annular elastic ring 9321 may extend outwards to form a groove mating portion, which can mate with the second groove. This not only facilitates installation and disassembly but also ensures that the second annular elastic ring 9321 can be stably fixed between the outer wall of the outer ring ejector tube 322 and the wall of the second through hole 922.

[0260] See also Figure 44 and Figure 45 A support 310 can be installed below the liquid collection tray 90. The inner ring ejector tube 321 and the outer ring ejector tube 322 can be positioned by the support 310. The outer ring 362 of the second annular elastic ring 9321 can extend outward to form a support section 9322. The support section 9322 can have a first end 9322a and a second end 9322b. The first end 9322a can abut against the upper surface of the support 310. The lower surface of the liquid collection tray 90 can abut against the second end 9322b. In this way, the support section 9322 is supported between the support 310 and the liquid collection tray 90, thereby ensuring that the second annular elastic ring 9321 can be stably fixed between the outer wall surface of the outer ring ejector tube 322 and the hole wall of the second through hole 922. In addition, the second annular elastic ring 9321 can also extend in a direction perpendicular to the panel 20 to be supported on the bracket 310, which can also ensure that the second annular elastic ring 9321 is stably fixed between the outer wall surface of the outer ring ejector tube 322 and the hole wall of the second through hole 922.

[0261] See also Figures 47 to 49 The burner head 30 may also include an ejector tube 320 and a support 310. The ejector tube 320 can be positioned by the support 310. The support 310 can be positioned below the liquid-holding tray 90. The ejector tube 320 can pass through the support 310 and the liquid-holding tray 90 sequentially from bottom to top, and the ejector tube 320 can be positioned by the support 310. The temperature-sensing surface 410 can be disposed on the support 310. Thus, since the temperature of the support 310 is related to the temperature of the pot bottom, the temperature of the pot bottom can be detected by sensing the temperature of the support 310 by the temperature-sensing element 40 (i.e., indirect detection of the pot temperature). The temperature-sensing element 40 is not affected by the flame, which not only ensures the accuracy and speed of temperature detection, but also ensures that the temperature-sensing element 40 will not interfere with the pot even when using a pointed-bottom pot, thus expanding the applicability of the stove 1. Of course, the temperature-sensing surface 410 can also be disposed on the heat-conducting element 350 or the ejector tube 320.

[0262] See also Figures 47 to 49 The liquid-holding tray 90 may have a first tray portion 941 and a second tray portion 942. The second tray portion 942 may be lower than the first tray portion 941. The first tray portion 941 may be closer to the center of the liquid-holding tray 90 than the second tray portion 942. The projection of the temperature-sensing surface 410 onto the plane containing the first tray portion 941 may fall within the first tray portion 941. The liquid-holding tray 90 may be made of metal, which is not only easy to clean but also resistant to high temperatures and liquid corrosion. Thus, because the second tray portion 942 is lower than the first tray portion 941, the liquid on the first tray portion 941 can flow to the second tray portion 942, reducing the influence of the liquid temperature on the first tray portion 941 on the temperature-sensing element 40 and further ensuring the accuracy of the detection results of the temperature-sensing element 40.

[0263] Specifically, in embodiments where the ejector tube 320 may include an inner ring ejector tube 321 and an outer ring ejector tube 322, the inner ring ejector tube 321 is positioned closer to the center of the liquid-holding tray 90 than the outer ring ejector tube 322. Since the first tray portion 941 is positioned close to the center of the liquid-holding tray 90, the inner ring ejector tube 321 can pass through the first tray portion 941. A first through-hole 921 may be provided on the first tray portion 941, through which the inner ring ejector tube 321 can pass. The first tray portion 941 is higher than the second tray portion 942, allowing liquid on the first tray portion 941 to flow towards the second tray portion 942, reducing the amount of liquid on the first tray portion 941 flowing into the liquid-holding tray 90 from the first through-hole 921 and affecting the detection of the temperature sensing element 40. To satisfy the positional relationship between the inner ring ejector tube 321 and the outer ring ejector tube 322, the outer ring ejector tube 322 can pass through the second tray portion 942. A second through hole 922 may be provided on the second plate 942, and the outer ring ejector tube 322 may be inserted through the second through hole 922.

[0264] A first connecting portion 944 may be provided between the first plate portion 941 and the second plate portion 942. The first connecting portion 944 may be inclined or arc-shaped to better guide the liquid from the first plate portion 941 to the second plate portion 942.

[0265] See again Figures 47 to 49The liquid-collecting tray 90 may also have a third tray portion 943, which may be higher than the second tray portion 942. The second tray portion 942 may be connected between the first tray portion 941 and the third tray portion 943. Thus, the second tray portion 942 is lower than the first tray portion 941 and the third tray portion 943, and the second tray portion 942 forms the bottom of the liquid-collecting tray 90, preventing the liquid collected by the second tray portion 942 from flowing around and affecting other components. Furthermore, a second connecting portion 945 may be provided between the second tray portion 942 and the third tray portion 943. The second connecting portion 945 may also be inclined or arc-shaped to better guide the liquid from the third tray portion 943 to the second tray portion 942. A liquid-collecting cavity 910 may be formed at the position of the second tray portion 942, which can collect liquid splashed during cooking, preventing the liquid from flowing around and affecting the operation of other components.

[0266] See Figure 48 and Figure 49 A second distance Z2 can be provided between the temperature-sensing surface 410 and the lower surface of the first disk 941. This second distance Z2 can be 5mm to 12mm, for example, 5mm, 7.5mm, 10mm, or 12mm. Within this range, the second distance Z2 not only prevents the temperature of the first disk 941 (i.e., the temperature conducted from the ejector tube 320 to the first disk 941) or the temperature of the liquid remaining on the first disk 941 from affecting the detection result of the temperature-sensing element 40 due to the first disk 941 being too close to the temperature-sensing surface 410, but also facilitates the formation of a first cavity 951 between the temperature-sensing surface 410 and the lower surface of the first disk 941. Heat generated by the ejector tube 320 can dissipate outwards from the first cavity 951, preventing excessive heat concentration from affecting the measurement result of the temperature-sensing element 40, thus ensuring the accuracy of the detection result of the temperature-sensing element 40. In one embodiment of this invention, the second distance Z2 is 7.5mm, which effectively ensures the accuracy of the detection result of the temperature-sensing element 40.

[0267] See again Figure 48 and Figure 49 A ninth spacing Z9 may be provided between the temperature sensing surface 410 and the lower surface of the second disk 942. This ninth spacing Z9 can be 3mm to 8mm, for example, 3mm, 4.6mm, 6mm, or 8mm. Within this range, the temperature of the second disk 942 (i.e., the temperature conducted from the ejector tube 320 to the second disk 942 via the first disk 941) or the temperature of the liquid received by the second disk 942 avoids affecting the detection result of the temperature sensing element 40, thus ensuring the accuracy of the detection result. In one embodiment of this invention, the ninth spacing Z9 is 4.6mm, which effectively ensures the accuracy of the detection result of the temperature sensing element 40.

[0268] See also Figures 47 to 49 The ejector tube 320 can be positioned on the bottom shell 10 via a bracket 310. The bracket 310 may have a plate-shaped body 311. A temperature-sensing surface 410 can be disposed on the plate-shaped body 311. The temperature-sensing surface 410 can be attached to the plate-shaped body 311 so that the temperature-sensing surface 410 can directly detect the heat of the plate-shaped body 311. The temperature-sensing surface 410 can also be fixed to the plate-shaped body 311 via a heat-conducting element 350, and the temperature-sensing surface 410 can transfer heat through the heat-conducting element 350 to detect the heat of the plate-shaped body 311. The temperature-sensing surface 410 may be disposed on the lower surface of the plate-shaped body 311. The upper surface of the plate-shaped body 311 and the lower surface of the first disk portion 941 may be spaced apart to form a first cavity 951. In this way, the heat generated by the ejector tube 320 is dissipated into the first cavity 951 and then outward through the first cavity 951. This avoids excessive heat concentration that could affect the measurement results of the temperature sensing element 40, thus ensuring the accuracy of the detection results of the temperature sensing element 40. Furthermore, the bracket 310 may also have a support leg 312, which can be used to support the plate-shaped body 311, thereby ensuring that the ejector tube 320 can be positioned by the bracket 310.

[0269] See again Figures 47 to 49 The upper surface of the plate-shaped body 311 and the lower surface of the second disk portion 942 can be spaced apart to form a second cavity 952, which can be connected to the first cavity 951. In this way, the heat generated by the ejector tube 320, after being dissipated to the first cavity 951, can be further dissipated outward through the second cavity 952, thereby avoiding excessive heat concentration that could affect the measurement results of the temperature sensing element 40, and thus ensuring the accuracy of the detection results of the temperature sensing element 40.

[0270] See again Figures 47 to 49 The third plate 943, together with the panel 20, forms a third cavity 953, which is connected to the second cavity 952. In this way, heat dissipated into the second cavity 952 can be further dissipated outward through the third cavity 953, achieving thermal equilibrium below the liquid-filled plate 90. This prevents excessive heat concentration from affecting the measurement results of the temperature sensor 40, thus ensuring the accuracy of the temperature sensor 40's detection results.

[0271] Furthermore, a tenth spacing Z10 can be provided between the third disc portion 943 and the panel 20. The tenth spacing Z10 can be 2mm to 7mm, for example, 2mm, 4.8mm, 6mm, or 7mm. Thus, the lower surface of the third disc portion 943 and the upper surface of the panel 20 can enclose and form a third cavity 953. Heat is sequentially dissipated from the ejector tube 320 through the first cavity 951, the second cavity 952, and the third cavity 953. In the presence of a bulge, heat can also be dissipated from the first cavity 951 into the cavity 9461. This allows thermal equilibrium to be achieved below the liquid-holding tray 90, preventing excessive heat concentration from affecting the measurement results of the temperature sensing element 40, thereby ensuring the accuracy of the temperature sensing element 40's detection results. In one embodiment of this invention, the tenth spacing Z10 is 4.8mm, which effectively ensures the accuracy of the temperature sensing element 40's detection results.

[0272] See Figure 47 A protrusion 946 may be formed on the liquid-holding tray 90 at the position directly opposite the temperature-sensing element 40. The protrusion 946 may protrude away from the temperature-sensing element 40 and form a cavity 9461. The protrusion 946 may be disc-shaped or box-shaped, etc. Specifically, the protrusion 946 may be formed on the first tray portion 941. Thus, on the one hand, the protrusion 946 protrudes away from the temperature sensing element 40, which not only allows the liquid remaining on the protrusion 946 to flow to the first disk 941 and the second disk 942, further reducing the influence of the temperature of the remaining liquid on the temperature sensing element 40, but also moves it further away from the temperature sensing surface 410, avoiding the temperature of the protrusion 946 (i.e., the temperature conducted from the ejector tube 320 to the protrusion 946 through the first disk 941) or the temperature of the small amount of liquid remaining on the protrusion 946 from affecting the detection result of the temperature sensing element 40; on the other hand, the protrusion 946 forms a cavity 9461, and the heat generated by the ejector tube 320 is dissipated into the cavity 9461 and dissipated outward through the cavity 9461, avoiding excessive heat concentration that would affect the measurement result of the temperature sensing element 40, thereby ensuring the accuracy of the detection result of the temperature sensing element 40; in addition, when the temperature sensing element 40 is fixed by the fastener 331, the protrusion 946 can also avoid the fastener 331, thereby avoiding mutual interference.

[0273] Furthermore, when the temperature sensing element 40 is fixed by the fastener 331, the distance between the protrusion 946 and the fastener 331 can be greater than 1mm, such as 1mm, 1.5mm, or 2mm. This effectively avoids interference between the protrusion 946 and the fastener 331. In one embodiment of this invention, the distance between the top ends of the fasteners 331 is 1.5mm, which effectively ensures that the protrusion 946 and the fastener 331 will not interfere with each other.

[0274] See again Figures 47 to 49The protrusion 946 may have a convex top wall 9462. A third distance Z3 may be present between the lower surface of the convex top wall 9462 and the lower surface of the first disk portion 941. This third distance Z3 can be 4mm to 14mm, for example, 4mm, 7mm, 9mm, or 14mm. Within this range, the third distance Z3 not only allows the liquid remaining on the protrusion 946 to flow to the first disk portion 941 and the second disk portion 942, further reducing the influence of the remaining liquid temperature on the temperature sensing element 40, but also prevents the temperature of the protrusion 946 or the temperature of a small amount of liquid remaining on the protrusion 946 from affecting the detection result of the temperature sensing element 40, thereby ensuring the accuracy of the detection result of the temperature sensing element 40. In one embodiment of this invention, the third distance Z3 is 9mm, which effectively ensures the accuracy of the detection result of the temperature sensing element 40.

[0275] In an embodiment where the temperature-sensing surface 410 can be attached to the lower surface of the plate-shaped body 311, the upper surface of the plate-shaped body 311 and the lower surface of the second disc portion 942 can have an eleventh distance Z11, and the plate-shaped body 311 can have a thickness h, where Z11 = Z9 - h. Thus, on the one hand, the surface to be measured 301 is located on the lower surface of the plate-shaped body 311, which not only avoids the influence of flame combustion on temperature detection and ensures the accuracy of temperature detection, but also effectively prevents leaked soup from contacting the temperature-sensing element 40 and affecting the accuracy and service life of the temperature-sensing element 40; on the other hand, the second cavity 952 formed between the upper surface of the plate-shaped body 311 and the lower surface of the second disc portion 942 can further dissipate the heat generated by the ejector tube 320, thereby preventing excessive heat concentration from affecting the measurement results of the temperature-sensing element 40.

[0276] The thickness h can be from 0.5mm to 3mm, for example, 0.5mm, 1mm, 3mm, etc. Within this range, the thickness h ensures the accuracy of temperature detection by the temperature sensing element 40 and the strength of the plate-shaped body 311. This avoids both excessively thin plate-shaped body 311 (which would result in poor strength) and excessively thick plate-shaped body 311 (which would slow down the temperature conduction to the temperature sensing element 40 and affect its temperature detection). In one embodiment of this invention, the thickness h is 1mm, which effectively ensures the accuracy of temperature detection by the temperature sensing element 40.

[0277] The center of the temperature-sensing surface 410 can be projected onto the plane of the panel 20 within the through hole 210. Furthermore, along the length of the panel 20, a third distance L3 can exist between the center of the temperature-sensing surface 410 and the wall of the through hole 210. This third distance L3 can be 40mm to 90mm, for example, 40mm, 55mm, 70mm, or 90mm. Within this predetermined range, the heat from the panel 20 avoids affecting the detection results of the temperature-sensing element 40, thus ensuring the accuracy of the detection results. In one embodiment of this invention, the third distance L3 is 70mm, which effectively ensures the accuracy of the detection results. The panel 20 can be made of stainless steel or glass, which is not only easy to clean but also resistant to liquid corrosion.

[0278] See also Figure 47 and Figure 48 The through hole 210 can have a radius of R5, and the outer edge 9421 of the second disc 942 can be formed on a circumference with a radius of R6 centered on the center of the through hole 210, where R6 < R5. Thus, since the second disc 942 is lower than the first disc 941 and the third disc 943, the second disc 942 forms the bottom of the liquid-holding tray 90. Liquid on the first disc 941 and the third disc 943 can flow to the second disc 942. Because R6 < R5, this not only ensures that the second disc 942 can form a liquid-holding cavity 910 with sufficient volume, preventing the liquid from overflowing due to its small size and affecting other components, but also facilitates the formation of a heat dissipation channel between the second disc 942 and the wall of the through hole 210 of the panel 20. This prevents heat accumulation from affecting the measurement results of the temperature sensing element 40, thereby ensuring the accuracy of the temperature sensing element 40's detection results.

[0279] See again Figure 47 and Figure 48 The through hole 210 can have a radius of R5, and the third disk 943 can have an inner edge 9431 and an outer edge 9432. The inner edge 9431 can be formed on a circumference with a radius of R7 centered on the center of the through hole 210, and the outer edge 9432 can be formed on a circumference with a radius of R8 centered on the center of the through hole 210, where R7 < R5 < R8. This ensures that the liquid-holding disk 90 is supported on the panel 20 and also facilitates the formation of a heat dissipation channel below the third disk 943, preventing excessive heat concentration from affecting the measurement results of the temperature sensing element 40, thus ensuring the accuracy of the detection results of the temperature sensing element 40.

[0280] See again Figure 47 and Figure 48The through hole 210 can have a radius R5, which can be 60mm to 90mm, for example, R5 can be 60mm, 70mm, 85mm, 90mm, etc. Thus, with the radius R5 of the through hole 210 within this range, not only is the distance between the center of the temperature sensing surface 410 and the hole wall of the through hole 210 ensured, preventing the panel 20 from being too close to the temperature sensing surface 410 and thus affecting the detection result of the temperature sensing element 40, but it also ensures heat dissipation below the liquid tray 90, preventing excessive heat concentration from affecting the measurement result of the temperature sensing element 40, thereby ensuring the accuracy of the detection result of the temperature sensing element 40. In one embodiment of this utility model, R5 is 85mm, which effectively ensures the accuracy of temperature detection by the temperature sensing element 40.

[0281] See also Figures 50 to 52 The bottom shell 10 has a cavity bottom wall 130 opposite to the panel 20. The cavity bottom wall 130 has a first region 131 and a second region 132. The temperature sensing element 40 has a sensing surface 410, which is spaced apart from the first region 131 and the second region 132. In this way, the sensing surface is spaced apart from the first region 131 and the second region 132, which can ensure that the temperature sensing element 40 has sufficient heat dissipation space, avoiding the accumulation of heat generated by the temperature sensing element 40 in its vicinity, which would affect and damage the temperature sensing element 40. This effectively improves the detection accuracy and service life of the temperature sensing element 40, and enhances the safety and reliability of the stove 1.

[0282] In the direction perpendicular to the panel 20, the first region 131 is farther away from the panel 20 than the second region 132, and there is a fourth spacing Z4 between the sensing surface and the first region 131, which is 35mm to 80mm.

[0283] See also Figure 50 and Figure 52 An adjacent first region 131 and a second region 132 can be formed on the bottom wall 130 of the cavity. Electronic components can be disposed on the first region 131. The distance between the temperature sensing element 40 and the first region 131 in the vertical direction is greater than the distance between the temperature sensing element 40 and the second region 132 in the vertical direction, thereby giving the electronic components a larger heat dissipation space and heat dissipation range.

[0284] Specifically, the fourth spacing Z4 ranges from 35 mm to 80 mm, for example, 35 mm, 50 mm, 60 mm, 70 mm, 80 mm, etc. Within this range, the fourth spacing Z4 can prevent heat from accumulating near the temperature sensing element 40, thereby avoiding any impact or damage to the temperature sensing element 40. In one embodiment of this utility model, the fourth spacing Z4 is 60 mm. With this distance value, the detection accuracy and service life of the temperature sensing element 40 are well guaranteed.

[0285] Thus, the fourth distance Z4 between the sensing surface and the first region 131 ensures that the temperature sensing element 40 has sufficient heat dissipation space, preventing the heat generated by the temperature sensing element 40 from accumulating nearby and affecting or damaging the temperature sensing element 40. This effectively improves the detection accuracy and service life of the temperature sensing element 40, and enhances the safety and reliability of the stove 1.

[0286] See Figure 50 and Figure 51 The control valve 50 may include a valve body 520 and a controller 510. The valve body 520 and the controller 510 may be electrically connected. When the temperature value sensed by the temperature sensor 40 changes more than a threshold or / and the temperature value sensed by the temperature sensor 40 is higher than a preset temperature, the controller 510 may control the valve body 520 to disconnect the gas supply line.

[0287] In some embodiments, in conjunction with reference Figure 50 and Figure 51 The control valve 50 is at least partially positioned corresponding to the first region 131, and the first region 131 is provided with a first heat dissipation hole 151 for dissipating heat from at least part of the control valve 50. Specifically, the first heat dissipation hole 151 is positioned corresponding to the controller 510, and the first heat dissipation hole 151 can dissipate heat from the controller 510. In this way, the first heat dissipation hole 151 can be formed on the first region 131, and the first heat dissipation hole 151 can dissipate the heat generated by at least part of the control valve 50 through the first heat dissipation hole 151, avoiding the accumulation of heat that may affect or damage the at least part of the control valve 50 and the temperature sensing element 40, effectively improving the detection accuracy of the temperature sensing element 40, as well as the service life of the temperature sensing element 40 and at least part of the control valve 50, thereby improving the safety and reliability of the stove 1.

[0288] The controller 510 and the first heat dissipation hole 151 can be correspondingly arranged on the first region 131 so that the heat generated by the controller 510 can be quickly discharged through the first heat dissipation hole 151 along a shorter airflow path, avoiding overheating that may occur in the area near the temperature sensing element 40 and the controller 510 due to heat concentration.

[0289] Specifically, the first heat dissipation hole 151 can be connected to the mounting cavity 110 to allow the mounting cavity 110 to communicate with the external environment. The shape and heat dissipation area of ​​the first heat dissipation hole 151 can be determined according to actual usage needs, and this application does not impose specific limitations on this. For example, the shape of the first heat dissipation hole 151 can be elongated or circular, etc.

[0290] In some embodiments, see Figure 51Along the length of the bottom shell 10, there is a fourth lateral distance X4 between the sensing surface and the first heat dissipation hole 151, which is 150mm to 280mm. This fourth lateral distance X4 ensures that the heat generated by the temperature sensing element 40 during operation can be dissipated through the first heat dissipation hole 151, and also prevents the heat generated by the burner head 30 from rapidly dissipating through the first heat dissipation hole 151, thus avoiding inaccurate sensing results from the temperature sensing element 40. This effectively improves the reliability and accuracy of the temperature sensing element 40.

[0291] Specifically, the fourth lateral distance X4 ranges from 150 mm to 280 mm, for example, 150 mm, 180 mm, 215 mm, 250 mm, 280 mm, etc. Within this range, the heat generated by the temperature sensing element 40 can be dissipated in a timely manner through the first heat dissipation hole 151, thereby avoiding any impact or damage to the temperature sensing element 40. In one embodiment of this utility model, the fourth lateral distance X4 is 215 mm. Under this distance value, the detection accuracy and service life of the temperature sensing element 40 are well guaranteed.

[0292] Understandably, the fourth lateral distance X4 between the sensing surface and the first heat dissipation hole 151 should not be too large or too small. When the fourth lateral distance X4 is too large, the heat generated by the temperature sensing element 40 during operation cannot be dissipated through the first heat dissipation hole 151, causing the heat generated by the temperature sensing element 40 to accumulate in the mounting cavity 110, thereby affecting and damaging the temperature sensing element 40. When the fourth lateral distance X4 is too small, the heat generated by the burner head 30 may be quickly dissipated through the first heat dissipation hole 151, thereby affecting the sensing result of the temperature sensing element 40. Specifically, it may cause the value sensed by the temperature sensing element 40 to be too low, failing to accurately reflect the actual sensed value, thus affecting the accuracy of the sensing result of the temperature sensing element 40.

[0293] In some embodiments, see Figure 51 In the width direction of the bottom shell 10, there is a fourth longitudinal distance Y4 between the sensing surface and the first heat dissipation hole 151, and the fourth longitudinal distance Y4 is 30mm to 85mm. In this way, the longitudinal distance range between the sensing surface and the first heat dissipation hole 151 not only ensures that the heat generated by the temperature sensing element 40 during operation can be discharged through the first heat dissipation hole 151, but also avoids the heat generated by the burner head 30 from being lost too quickly through the first heat dissipation hole 151, thereby preventing the temperature sensing element 40 from providing inaccurate sensing results, effectively improving the reliability and accuracy of the temperature sensing element 40.

[0294] Specifically, the fourth longitudinal interval Y4 ranges from 30 mm to 85 mm, for example, 30 mm, 50 mm, 65 mm, 70 mm, 85 mm, etc. Within this range, the heat generated by the temperature sensing element 40 can be dissipated in a timely manner through the first heat dissipation hole 151, thereby avoiding any impact or damage to the temperature sensing element 40. In one embodiment of this utility model, the fourth longitudinal interval Y4 is 65 mm. Under this distance value, the detection accuracy and service life of the temperature sensing element 40 are well guaranteed.

[0295] Understandably, the fourth longitudinal interval Y4 between the sensing surface and the first heat dissipation hole 151 should not be too large or too small. When the fourth longitudinal interval Y4 is too large, the heat generated by the temperature sensing element 40 during operation cannot be dissipated through the first heat dissipation hole 151, causing the heat generated by the temperature sensing element 40 to accumulate in the mounting cavity 110, thereby affecting and damaging the temperature sensing element 40. When the fourth longitudinal interval Y4 is too small, the heat generated by the burner head 30 may be quickly dissipated through the first heat dissipation hole 151, thereby affecting the sensing result of the temperature sensing element 40. Specifically, it may cause the value sensed by the temperature sensing element 40 to be too low, failing to accurately reflect the actual sensed value, thus affecting the accuracy of the sensing result of the temperature sensing element 40.

[0296] In some embodiments, see Figure 51 Multiple first heat dissipation holes 151 are provided, spaced apart along the width of the bottom shell 10. This increases the contact area between heat and the external environment, allowing the heat generated by the controller 510 to be more evenly distributed, effectively improving the heat dissipation efficiency of the cooktop 1 and increasing its stability and lifespan.

[0297] Specifically, the spacing between the plurality of first heat dissipation holes 151 in the width direction of the bottom shell 10 can be determined according to the actual situation or usage requirements, and this application does not impose specific limitations on this. For example, when it is necessary to ensure that the heat dissipation area of ​​the first heat dissipation holes 151 can cover the first region 131, the spacing between the plurality of first heat dissipation holes 151 can be 10 mm.

[0298] In some embodiments, in conjunction with reference Figure 50 and Figure 51The bottom shell 10 has a cavity sidewall 140 located between the cavity bottom wall 130 and the panel 20. The second region 132 has an inner region 1321 and an outer region 1322. The outer region 1322 is closer to the cavity sidewall 140 than the inner region 1321. The projection of the temperature sensing element 40 onto the plane of the cavity bottom wall 130 is located in the inner region 1321. A second heat dissipation hole 152 for heat dissipation of the temperature sensing element 40 is provided on the inner region 1321. Thus, the heat generated by the temperature sensing element 40 can be discharged from the mounting cavity 110 in a timely manner through the second heat dissipation hole 152 provided in the inner region 1321. Furthermore, the temperature sensing element 40 can be located above the inner region 1321 so that the hot airflow in the mounting cavity 110 can be quickly discharged along a shorter airflow path, avoiding overheating that may occur due to heat concentration in the area near the temperature sensing element 40, and further improving the sensing accuracy and service life of the temperature sensing element 40.

[0299] Specifically, the bottom wall 130 and the side wall 140 of the cavity of the bottom shell 10 can be detachably connected or integrally formed. The detachable connection can include plug-in connection or adhesive connection, etc., and this application does not make specific limitations in this regard.

[0300] Specifically, the controller 510 can be set to correspond with the first area 131, and the temperature sensing element 40 can be set to correspond with the internal area 1321. Through the first heat dissipation hole 151 set on the first area 131 and the second heat dissipation hole 152 set on the internal area 1321, the controller 510 and the temperature sensing element 40 can have different heat dissipation channels, which effectively ensures the heat dissipation effect and heat dissipation efficiency of the stove 1.

[0301] Specifically, the second heat dissipation hole 152 can be connected to the mounting cavity 110 to allow the mounting cavity 110 to communicate with the external environment. The shape and heat dissipation area of ​​the second heat dissipation hole 152 can be determined according to actual usage needs, and this application does not impose specific limitations on this. For example, the shape of the second heat dissipation hole 152 can be elongated or circular, etc.

[0302] In an embodiment not shown, there may be multiple second heat dissipation holes 152, and these multiple second heat dissipation holes 152 may be spaced apart on the inner region 1321.

[0303] In some embodiments, in conjunction with reference Figure 50 and Figure 52In a direction perpendicular to the panel 20, there is a twelfth distance Z12 between the sensing surface and the internal area 1321, with the twelfth distance Z12 being 35mm to 75mm. This second distance range between the sensing surface and the internal area 1321 not only ensures that the heat generated by the temperature sensor 40 during operation can be dissipated through the second heat dissipation hole 152 located on the internal area 1321, but also prevents the heat generated by the burner head 30 from rapidly dissipating through the second heat dissipation hole 152 located on the internal area 1321, thus avoiding inaccurate sensing results from the temperature sensor 40. This effectively improves the reliability and accuracy of the temperature sensor 40.

[0304] Specifically, the twelfth spacing Z12 ranges from 35 mm to 75 mm, for example, 35 mm, 45 mm, 55 mm, 65 mm, 75 mm, etc. When the second spacing Z2 is within this range, the heat generated by the temperature sensing element 40 can be promptly dissipated through the second heat dissipation hole 152, thereby avoiding any impact or damage to the temperature sensing element 40. In one embodiment of this utility model, the twelfth spacing Z12 is 55 mm. At this distance, the detection accuracy and service life of the temperature sensing element 40 are well guaranteed.

[0305] Understandably, the twelfth spacing Z12 between the sensing surface and the internal area 1321 should not be too large or too small. When the twelfth spacing Z12 is too large, the heat generated by the temperature sensing element 40 during operation cannot be dissipated through the second heat dissipation hole 152 located on the internal area 1321, causing the heat generated by the temperature sensing element 40 to accumulate in the mounting cavity 110, thereby affecting and damaging the temperature sensing element 40. When the twelfth spacing Z12 is too small, the heat generated by the burner head 30 may be quickly dissipated through the second heat dissipation hole 152 located on the internal area 1321, thereby affecting the sensing result of the temperature sensing element 40. Specifically, it may cause the value sensed by the temperature sensing element 40 to be too low, failing to accurately reflect the actual sensed value, thus affecting the accuracy of the sensing result of the temperature sensing element 40.

[0306] In some embodiments, see Figure 51 The second heat dissipation hole 152 is a circular hole, and the projection of the sensing surface onto the plane of the cavity bottom wall 130 is located inside the circular hole. In this way, the sensing surface of the temperature sensing element 40 can be located directly above the second heat dissipation hole 152, and the heat generated by the temperature sensing element 40 can be dissipated through the second heat dissipation hole 152 in the first instance, thereby ensuring that the temperature sensing element 40 can always be in a stable and suitable working environment temperature, effectively improving the sensing accuracy and service life of the temperature sensing element 40, and further improving the safety and reliability of the stove 1.

[0307] In some embodiments, in conjunction with reference Figures 50 to 52The burner head 30 includes an ejector tube 320 and a support 310. The ejector tube 320 is positioned by the support 310, and a thermocouple 370 is mounted on the support 310. A third heat dissipation hole 153 for heat dissipation of the thermocouple 370 is provided on the outer periphery 1322. Thus, by mounting the ejector tube 320 and the thermocouple 370 on the support 310, the overall structural design of the burner head 30 can be optimized, making it more compact and stable. Furthermore, the positioning of the ejector tube 320 and the thermocouple 370 by the support 310 simplifies the assembly process of the burner head 30, reduces assembly steps and time, and facilitates subsequent maintenance and replacement, greatly reducing maintenance costs. Furthermore, the heat generated by the thermocouple 370 can be discharged through the third heat dissipation hole 153, which avoids the impact and damage to the temperature sensing element 40 and the thermocouple 370 caused by heat accumulation, effectively improving the detection accuracy of the temperature sensing element 40 and the service life of the temperature sensing element 40 and the thermocouple 370, thereby improving the safety and reliability of the stove 1.

[0308] See again Figures 50 to 52 There can be multiple third heat dissipation holes 153, and these multiple third heat dissipation holes 153 can be spaced apart along the width direction of the bottom shell 10 to improve the heat dissipation efficiency and effect of the thermocouple 370.

[0309] See Figure 51 In the embodiment where the sensing surface and the bracket 310 form a surface contact, a fifth lateral distance X5 exists between the sensing surface and the third heat dissipation hole 153 along the length of the bottom shell 10. This fifth lateral distance X5 is 35mm to 75mm. Thus, the surface contact significantly increases the contact area between the temperature sensing element 40 and the bracket 310, thereby reducing contact thermal resistance and allowing heat from the bracket 310 to be quickly and evenly transferred to the temperature sensing element 40. Furthermore, the aforementioned second lateral distance range between the sensing surface and the third heat dissipation hole 153 not only ensures that the heat generated by the temperature sensing element 40 during operation can be dissipated through the third heat dissipation hole 153, but also prevents the heat transferred to the bracket 310 from rapidly dissipating through the third heat dissipation hole 153, thus avoiding inaccurate sensing results from the temperature sensing element 40. This effectively improves the reliability and accuracy of the temperature sensing element 40.

[0310] Specifically, the fifth lateral distance X5 ranges from 35 mm to 75 mm, such as 35 mm, 45 mm, 55 mm, 65 mm, and 75 mm. Within this range, the heat generated by the temperature sensing element 40 can be dissipated in a timely manner through the third heat dissipation hole 153, thereby avoiding any impact or damage to the temperature sensing element 40. In one embodiment of this invention, the fifth lateral distance X5 is 55 mm. This distance value effectively ensures the detection accuracy and service life of the temperature sensing element 40.

[0311] Understandably, the fifth lateral distance X5 between the sensing surface and the third heat dissipation hole 153 should not be too large or too small. When the fifth lateral distance X5 is too large, the heat generated by the temperature sensing element 40 during operation cannot be dissipated through the third heat dissipation hole 153, causing the heat generated by the temperature sensing element 40 to accumulate in the mounting cavity 110, thereby affecting and damaging the temperature sensing element 40. When the fifth lateral distance X5 is too small, the heat transferred to the bracket 310 may be quickly dissipated through the third heat dissipation hole 153, thereby affecting the sensing result of the temperature sensing element 40. Specifically, it may cause the value sensed by the temperature sensing element 40 to be too low, failing to accurately reflect the actual sensed value, thus affecting the accuracy of the sensing result of the temperature sensing element 40.

[0312] See Figure 51 In the embodiment where the sensing surface and the ejector tube 320 form a surface contact, a sixth lateral distance X6 exists between the sensing surface and the third heat dissipation hole 153 along the length of the bottom shell 10. This sixth lateral distance X6 is 35mm to 75mm. Thus, the surface contact significantly increases the contact area between the temperature sensing element 40 and the ejector tube 320, thereby reducing contact thermal resistance and allowing heat from the ejector tube 320 to be quickly and evenly transferred to the temperature sensing element 40. Furthermore, the aforementioned sixth lateral distance X6 between the sensing surface and the third heat dissipation hole 153 not only ensures that the heat generated by the temperature sensing element 40 during operation can be dissipated through the third heat dissipation hole 153, but also prevents the heat transferred to the ejector tube 320 from rapidly dissipating through the third heat dissipation hole 153, thus avoiding inaccurate sensing results from the temperature sensing element 40. This effectively improves the reliability and accuracy of the temperature sensing element 40.

[0313] Specifically, the sixth lateral distance X6 ranges from 35 mm to 75 mm, for example, 35 mm, 45 mm, 55 mm, 65 mm, 75 mm, etc. Within this range, the heat generated by the temperature sensing element 40 can be dissipated in a timely manner through the third heat dissipation hole 153, thereby avoiding any impact or damage to the temperature sensing element 40. In one embodiment of this utility model, the sixth lateral distance X6 is 55 mm. Under this distance value, the detection accuracy and service life of the temperature sensing element 40 are well guaranteed.

[0314] Understandably, the sixth lateral distance X6 between the sensing surface and the third heat dissipation hole 153 should not be too large or too small. When the sixth lateral distance X6 is too large, the heat generated by the temperature sensing element 40 during operation cannot be dissipated through the third heat dissipation hole 153, causing the heat generated by the temperature sensing element 40 to accumulate in the mounting cavity 110, thereby affecting and damaging the temperature sensing element 40. When the sixth lateral distance X6 is too small, the heat transferred to the ejector tube 320 may be quickly dissipated through the third heat dissipation hole 153, thereby affecting the sensing result of the temperature sensing element 40. Specifically, it may cause the value sensed by the temperature sensing element 40 to be too low, failing to accurately reflect the actual sensed value, thus affecting the accuracy of the sensing result of the temperature sensing element 40.

[0315] In some embodiments where the sensing surface and the heat-conducting element 350 form a surface contact, a seventh lateral distance X7 exists between the sensing surface and the third heat dissipation hole 153 along the length of the bottom shell 10. This seventh lateral distance X7 is 15mm to 105mm. When the heat-conducting element 350 and the bracket 310 are not of the same structure, the position of the sensing surface 410 on the heat-conducting element 350 can be on the same axis as its position on the bracket 310. The seventh lateral distance X7 can be equal to the fifth lateral distance X5. Thus, the surface contact significantly increases the contact area between the sensing element 40 and the heat-conducting element 350, thereby reducing contact thermal resistance and allowing heat from the heat-conducting element 350 to be quickly and evenly transferred to the sensing element 40. Furthermore, the seventh lateral distance X7 range between the sensing surface and the third heat dissipation hole 153 not only ensures that the heat generated by the temperature sensing element 40 during operation can be discharged through the third heat dissipation hole 153, but also prevents the heat transferred to the heat conduction element 350 from being quickly lost through the third heat dissipation hole 153, thereby preventing the temperature sensing element 40 from having inaccurate sensing results, effectively improving the reliability and accuracy of the temperature sensing element 40.

[0316] Specifically, the value of the seventh lateral distance X7 ranges from 15 mm to millimeters (mm), such as 15 mm, 50 mm, 70 mm, 85 mm, 105 mm, etc. Within this range, the heat generated by the temperature sensing element 40 can be dissipated in a timely manner through the third heat dissipation hole 153, thereby avoiding any impact or damage to the temperature sensing element 40. In one embodiment of this utility model, the seventh lateral distance X7 is 70 mm. Under this distance value, the detection accuracy and service life of the temperature sensing element 40 are well guaranteed.

[0317] Understandably, the seventh lateral distance X7 between the sensing surface and the third heat dissipation hole 153 should not be too large or too small. When the seventh lateral distance X7 is too large, the heat generated by the temperature sensing element 40 during operation cannot be dissipated through the third heat dissipation hole 153, causing the heat generated by the temperature sensing element 40 to accumulate in the mounting cavity 110, which may affect or damage the temperature sensing element 40. When the seventh lateral distance X7 is too small, the heat on the heat-conducting element 350 may be quickly dissipated through the third heat dissipation hole 153, thus affecting the sensing result of the temperature sensing element 40. Specifically, it may cause the value sensed by the temperature sensing element 40 to be too low, failing to accurately reflect the actual sensed value, thereby affecting the accuracy of the sensing result of the temperature sensing element 40.

[0318] In some embodiments, see Figure 52 In a direction perpendicular to the panel 20, there is a thirteenth distance Z13 between the sensing surface and the peripheral area 1322, and the thirteenth distance Z13 is 40mm to 80mm. Thus, the presence of the aforementioned thirteenth distance Z13 between the sensing surface and the peripheral area 1322 not only ensures that the heat generated by the temperature sensing element 40 during operation can be dissipated through the third heat dissipation hole 153 located on the peripheral area 1322, but also prevents the heat transferred to the bracket 310 from rapidly dissipating through the third heat dissipation hole 153 located on the peripheral area 1322, thereby preventing inaccurate sensing results from the temperature sensing element 40. This effectively improves the reliability and accuracy of the temperature sensing element 40.

[0319] Specifically, the thirteenth spacing Z13 ranges from 40 mm to 80 mm, for example, 40 mm, 50 mm, 60 mm, 70 mm, 80 mm, etc. Within this range, the heat generated by the temperature sensing element 40 can be dissipated in a timely manner through the third heat dissipation hole 153, thereby avoiding any impact or damage to the temperature sensing element 40. In one embodiment of this utility model, the thirteenth spacing Z13 is 60 mm. Under this distance value, the detection accuracy and service life of the temperature sensing element 40 are well guaranteed.

[0320] It is understandable that the thirteenth distance Z13 between the sensing surface and the peripheral area 1322 should not be too large or too small. When the thirteenth distance Z13 is too large, the heat generated by the temperature sensing element 40 during operation cannot be dissipated through the third heat dissipation hole 153 located on the peripheral area 1322, causing the heat generated by the temperature sensing element 40 to accumulate in the mounting cavity 110, which may affect or damage the temperature sensing element 40. When the thirteenth distance Z13 is too small, the heat transferred to the bracket 310 may be quickly dissipated through the third heat dissipation hole 153 located on the peripheral area 1322, thereby affecting the sensing result of the temperature sensing element 40. Specifically, it may cause the value sensed by the temperature sensing element 40 to be too low, failing to accurately reflect the actual sensed value, thus affecting the accuracy of the sensing result of the temperature sensing element 40.

[0321] In some embodiments, in conjunction with reference Figure 50 and Figure 51 The projection of the bracket 310 onto the plane of the cavity bottom wall 130 is located in the inner area 1321. In this way, the bracket 310 can be positioned close to the second heat dissipation hole 152, and the heat transferred to the bracket 310 and the heat generated by the components located on the bracket 310 can be quickly discharged through the second heat dissipation hole 152, avoiding the accumulation of heat in the mounting cavity 110, and effectively improving the safety and reliability of the stove 1.

[0322] In some embodiments, see Figure 52 Multiple third heat dissipation holes 153 are arranged at intervals along the width of the bottom shell 10. In this way, multiple third heat dissipation holes 153 can increase the contact area between heat and the external environment, so that the heat generated by the thermocouple 370 can be more evenly distributed to the surrounding environment, effectively improving the heat dissipation efficiency of the stove 1, and increasing the stability and service life of the stove 1.

[0323] Specifically, the spacing between the plurality of third heat dissipation holes 153 in the width direction of the bottom shell 10 can be determined according to the actual situation or usage requirements, and this application does not impose specific limitations on this. For example, when it is necessary to ensure that the heat dissipation area of ​​the third heat dissipation holes 153 can cover the peripheral area 1322, the spacing between the plurality of third heat dissipation holes 153 can be 10 mm.

[0324] See also Figures 53 to 56 The temperature sensing element 40 includes a heat-conducting part 420, a sensing part 431, and a signal transmission line 432. It should be noted that the aforementioned lead part 430 includes the sensing part 431 and the signal transmission line 432. The heat-conducting part 420 has a temperature-sensing surface 410. The sensing part 431 is connected to the heat-conducting part 420, and the sensing part 431 obtains the temperature information of the burner head 30 through the temperature-sensing surface 410. The signal transmission line 432 is connected to the sensing part 431 to transmit the temperature information outward.

[0325] Thus, the temperature-sensing surface 410 on the heat-conducting part 420 can contact at least a portion of the burner head 30, thereby transferring heat to the sensing part 431. The sensing part 431 can convert the heat into specific temperature information and transmit it to the outside world through the signal transmission line 432, thereby realizing the temperature detection and monitoring of the burner head 30. Through the direct contact between the temperature sensing element 40 and at least a portion of the burner head 30, interference from the external environment can be avoided, effectively ensuring the accuracy of the temperature measurement results. The temperature sensing element 40 can indirectly detect the temperature of the pot bottom by detecting the temperature of one of the bracket 310, the ejector tube 320, and the heat-conducting part 350, avoiding the influence of the flame on the temperature sensing element 40, improving the safety and reliability of the stove 1. Even when using a pointed-bottom pot, the temperature sensing element 40 will not interfere with the pot, expanding the applicability of the stove 1.

[0326] Specifically, the two ends of the sensing part 431 can be connected to the heat-conducting part 420 and the signal transmission line 432 respectively. The heat-conducting part 420 can be used to transfer the heat on the surface of the burner head 30. The sensing part 431 can convert the sensed heat into temperature information. The signal transmission line 432 can transmit the temperature information to external devices. The above-mentioned split design can ensure that the structure and layout of the temperature sensing element 40 are more stable and reduce the risk of failure caused by the complex structure.

[0327] Furthermore, the heat-conducting part 420 can be plate-shaped. The plate-shaped heat-conducting part 420 can have a temperature-sensing surface 410 that is at least part of the burner head 30. Through the close contact between the temperature-sensing surface 410 and at least part of the surface of the burner head 30, the heat of at least part of the burner head 30 can be transferred to the sensing part 431 quickly and efficiently. This greatly reduces the loss and delay in the heat transfer process and ensures that the sensing part 431 can obtain more accurate temperature information.

[0328] Furthermore, the heat-conducting part 420 can be made of a material with good thermal conductivity, such as copper or aluminum. This application does not specifically limit the material of the heat-conducting part 420; any material with good thermal conductivity is acceptable.

[0329] Of course, the shape of the heat-conducting part 420 can be determined according to at least part of the shape and size of different burner heads 30 to meet different usage scenarios and needs. For example, the shape of the heat-conducting part 420 can be circular, square, or irregular, etc. This application does not specifically limit the shape of the heat-conducting part 420.

[0330] The aforementioned signal transmission line 432 can transmit the temperature information acquired by the sensing unit 431 to an external control system. During the transmission process, the signal transmission line 432 can effectively reduce the influence of electromagnetic interference, dust, humidity, and other factors on the signal, thereby improving the reliability of the temperature sensing element 40 and the accuracy of the temperature detection results.

[0331] In some embodiments, see Figure 56 The sensing unit 431 includes a housing 4311 and a sensing chip 4312. The sensing chip 4312 is disposed within the housing 4311, and one end of the signal transmission line 432 is connected to the sensing chip 4312. This allows the sensing chip 4312 to be housed within the housing 4311, effectively protecting it from external environmental influences such as dust, moisture, or mechanical impact, significantly improving its lifespan and reliability. Furthermore, the direct connection between the sensing chip 4312 and the signal transmission line 432 greatly reduces signal transmission delay, enabling the temperature sensing chip to quickly respond to temperature changes and transmit temperature information.

[0332] Specifically, the sensing chip 4312 can quickly respond to temperature changes and convert them into electrical signals. Furthermore, through the efficient heat transfer of the heat-conducting part 420, the sensing chip 4312 can more accurately capture minute temperature changes.

[0333] Specifically, the sensing chip 4312 can be disposed within the housing 4311 to prevent interference or influence from external environments such as high temperature or moisture. A thermally conductive material, such as thermally conductive resin, can be filled between the housing 4311 and the sensing chip 4312. This not only eliminates air between the sensing chip 4312 and the housing 4311, reducing contact thermal resistance, but also improves the efficiency of heat transfer to the sensing chip 4312.

[0334] Furthermore, the shape of the sensing chip 4312 can be spherical or square, etc., to increase the contact area between the sensing chip 4312 and the heat-conducting material, thereby further improving the efficiency of heat transfer to the sensing chip 4312. This application does not specifically limit the shape of the sensing chip 4312.

[0335] Furthermore, the housing 4311 has an inclined surface 4311a that is inclined to the temperature sensing surface 410 of the heat-conducting part 420. The angle α formed by the inclined surface 4311a and the temperature sensing surface 410 is in the range of 30 degrees to 60 degrees (°), for example, 30°, 40°, 45°, 50°, 60°, etc., preferably 45°.

[0336] In some embodiments, the heat-conducting part 420 is configured as a sheet-like structure. In this way, the sheet-like structure of the heat-conducting part 420 can not only reduce the volume of the heat-conducting part 420 and reduce the overall weight of the temperature sensing element 40, but also have a large contact area with at least a portion of the surface of the burner head 30, effectively ensuring heat transfer and improving the heat conduction efficiency of the heat-conducting part 420.

[0337] In some embodiments, see Figure 56 The heat-conducting part 420 has a thickness h1, which is 0.4 mm to 1 mm. Thus, the heat-conducting part 420 with the thickness h1 range can ensure efficient heat transfer while reducing the size and weight of the heat-conducting part 420, effectively improving the practicality and flexibility of the temperature sensing element 40.

[0338] Specifically, the thickness h1 ranges from 0.4 mm to 1 mm, for example, 0.4 mm, 0.6 mm, 0.8 mm, 1 mm, etc., preferably 0.6 mm.

[0339] The heat-conducting portion 420 with the aforementioned thickness can quickly transfer heat from the temperature-sensing surface 410 to the sensing portion 431, reducing the residence time of heat within the heat-conducting portion 420 and thus improving the overall heat conduction speed of the temperature-sensing element 40. Furthermore, the heat-conducting portion 420 with the aforementioned thickness has low thermal resistance, enabling more efficient heat transfer and improving the accuracy of temperature information acquired by the sensing portion 431.

[0340] The heat-conducting portion 420 with the aforementioned thickness makes the temperature sensing element 40 suitable for use in space-constrained devices or systems, such as small electronic devices or high-density integrated devices, effectively improving the practicality of the temperature sensing element 40.

[0341] In some embodiments, see Figure 56 The heat-conducting part 420 is elongated. In this way, the elongated heat-conducting part 420 can quickly transfer heat from at least a portion of the burner head 30 to the temperature sensing chip, effectively reducing the accumulation of heat in the heat-conducting part 420, thereby improving the heat conduction efficiency of the heat-conducting part 420.

[0342] Of course, the heat-conducting part 420 can be adapted to the shape of at least part of the outer surface of the burner head 30 to ensure that the temperature-sensing surface 410 of the heat-conducting part 420 can be closely attached to at least part of the outer surface of the burner head 30, thereby ensuring accurate heat transfer.

[0343] In some embodiments, in conjunction with reference Figure 55 and Figure 56The heat-conducting part 420 has a length L7, which is 5mm to 15mm. Thus, the heat-conducting part 420 with the aforementioned length range effectively ensures that the heat generated by the burner head 30 is efficiently and accurately transferred to the sensing part 431 through the heat-conducting part 420, avoiding inaccurate sensing results from the sensing part 431 due to the heat-conducting part 420 being too long or too short, effectively improving the reliability and accuracy of the temperature sensing element 40.

[0344] Specifically, the length L7 ranges from 5 mm to 15 mm, for example, 5 mm, 8 mm, 10 mm, 15 mm, etc., preferably 10 mm.

[0345] The length of the heat-conducting part 420 should not be too long or too short. If the length of the heat-conducting part 420 is too long, heat loss may occur during the heat transfer process. If the length of the heat-conducting part 420 is too short, less heat may be transferred by the heat-conducting part 420, thereby affecting the accuracy of the temperature information obtained by the sensing part 431.

[0346] In some embodiments, see Figure 55 The heat-conducting part 420 has a width M, which is 3mm to 10mm. Thus, the heat-conducting part 420 with the aforementioned width range effectively ensures that the heat generated by the burner head 30 is efficiently and accurately transferred to the sensing part 431 through the heat-conducting part 420, avoiding inaccurate sensing results from the sensing part 431 due to the width of the heat-conducting part 420 being too large or too small, further improving the reliability and accuracy of the temperature sensing element 40.

[0347] Specifically, the width M ranges from 3 mm to 10 mm, for example, 3 mm, 6 mm, 8 mm, 10 mm, etc., with 6 mm being preferred.

[0348] The width of the heat-conducting part 420 should not be too long or too short. If the width of the heat-conducting part 420 is too large, heat loss may occur during the heat transfer process. If the width of the heat-conducting part 420 is too small, the amount of heat passing through the heat-conducting part 420 per unit time may decrease, resulting in a slower heat conduction speed of the heat-conducting part 420, which in turn affects the accuracy of the temperature information obtained by the sensing part 431.

[0349] In some embodiments, see Figure 56 The sensing unit 431 has a length L8, and the sensing chip 4312 and the end of the housing 4311 away from the heat-conducting part 420 have a length L9. L7:L8 = 1:3 to 1:1, and L9:L8 = 1:3 to 1:1. In this way, the components of the temperature sensing element 40 have suitable length ratios, which not only ensures that the temperature sensing element 40 has a good temperature sensing effect, but also improves the miniaturization and practicality of the temperature sensing element 40.

[0350] For example, the length L8 of the sensing part 431 ranges from 10 mm to 30 mm, such as 10 mm, 15 mm, 20 mm, 25 mm, 30 mm, etc., preferably 20 mm. The sensing part 431 with the above-mentioned length range avoids the temperature sensing element 40 from being too large due to the excessive length of the sensing part 431, and effectively ensures the miniaturization design of the temperature sensing element 40.

[0351] For example, the length L9 between the sensing chip 4312 and the end of the housing 4311 furthest from the heat-conducting part 420 ranges from 5 mm to 15 mm, such as 5 mm, 8 mm, 10 mm, 12 mm, 15 mm, etc., preferably 10 mm. This further ensures the contact area between the sensing chip 4312 and the heat-conducting material, thereby guaranteeing the accuracy and reliability of the detection results from the sensing chip 4312.

[0352] In some embodiments, the heat-conducting part 420 has an alloy material layer and an electroplated layer. The electroplated layer is formed on the surface of the alloy material layer, and a temperature-sensing surface 410 is formed on the outer surface of the electroplated layer away from the alloy material layer. Thus, the heat-conducting part 420 can be composed of an alloy material layer and an electroplated layer, and the temperature-sensing surface 410 can be formed on the electroplated layer. This not only simplifies the structure of the heat-conducting part 420, but also significantly improves the corrosion resistance, wear resistance, and thermal conductivity of the heat-conducting part 420. The electroplated layer can also prevent the heat-conducting part 420 from rusting, thereby extending the service life of the temperature-sensing element 40.

[0353] The electroplating layer effectively isolates the alloy material layer from the external environment, preventing corrosion and significantly improving the corrosion resistance of the heat-conducting part 420. Furthermore, the electroplating layer possesses high hardness and wear resistance, resisting external friction and abrasion, effectively extending the service life of the heat-conducting part 420.

[0354] Specifically, the alloy material layer can be made of copper, and the electroplating layer can be made of nickel. This application does not specifically limit the material of the alloy material layer and the electroplating layer.

[0355] In some embodiments, the temperature-sensing surface 410 has a sixth area S6, which is 30 mm² to 130 mm². Thus, the temperature-sensing surface 410 with the aforementioned area ensures sufficient contact between the temperature-sensing surface 410 and at least a portion of the burner head 30, thereby ensuring that heat can be quickly and efficiently transferred from at least a portion of the burner head 30 to the sensing portion 431 via the heat-conducting portion 420. Furthermore, the close contact between the temperature-sensing surface 410 and at least a portion of the burner head 30 significantly reduces contact thermal resistance, thereby improving the heat conduction efficiency of the heat-conducting portion 420.

[0356] Specifically, the value of the sixth area S6 ranges from 60 square millimeters to 80 square millimeters (mm2), for example, 30mm2, 65mm2, 68mm2, 75mm2, 130mm2, etc., with 68mm2 being preferred.

[0357] In some embodiments, the heat-conducting part 420 is provided with a through hole 423 for the fastener 331 to pass through. The through hole 423 has a seventh area S7, where S7:S6 = 1:5 to 1:2. Thus, the ratio between the area of ​​the through hole 423 and the area of ​​the temperature-sensing surface 410 of the heat-conducting part 420 can be in the range of 0.2 to 0.5. This not only ensures a tight connection between the temperature-sensing element 40 and at least a portion of the burner head 30, but also avoids the situation where the heat-conducting part 420 has poor heat conduction due to an excessively large area of ​​the through hole 423.

[0358] Specifically, the heat-conducting part 420 may be provided with a through hole 423, through which a fastener 331 can be connected to at least a portion of the burner head 30. The fastener 331 may be a bolt or a screw, and the diameter of the fastener 331 may be in the range of 3 mm to 6 mm, for example, 3 mm, 4 mm, 5 mm, 6 mm, preferably 4 mm. The length of the fastener 331 may be in the range of 4 mm to 8 mm, for example, 4 mm, 5 mm, 6 mm, 7 mm, 8 mm, preferably 6 mm.

[0359] Specifically, the hole area S7 can be from 8.5 mm² to 50.2 mm². For example, the hole area S7 can be 8.5 mm², 35 mm², 50.2 mm², etc. Setting the hole area S7 within this range avoids the problem of poor heat conduction of the heat-conducting part 420 due to an excessively large hole area S7. In one embodiment of this utility model, the hole area S7 can be 12.6 mm², thus effectively avoiding the problem of poor heat conduction of the heat-conducting part 420 due to an excessively large hole area S7.

[0360] See also Figures 57 to 61 The temperature sensing element 40 is positioned within the mounting cavity 110 by a fixing assembly 390. The fixing assembly 390 has a pressing member 391 and a fastening structure, the fastening structure being connected to the pressing member 391. The temperature sensing element 40 has a sensing surface 410 and a facing surface 440. The sensing surface 410 senses the temperature of the burner head 30, and the facing surface 440 is opposite to the sensing surface 410. The pressing member 391 is pressed against the facing surface 440 by the fastening structure, causing the sensing surface 410 to form surface contact with at least a portion of the burner head 30.

[0361] Specifically, at least a portion of the burner head 30 may be a support 310, an ejector tube 320, and a heat-conducting element 350. The sensing surface 410 of the temperature-sensing element 40 may be used to abut against one of the support 310, the ejector tube 320, and the heat-conducting element 350. The pressing member 391 may apply force to the opposing surface 440 of the temperature-sensing element 40 through a fastening structure to ensure that the temperature-sensing surface 410 can stably abut against one of the support 310, the ejector tube 320, and the heat-conducting element 350.

[0362] See again Figure 57 The shape of some of the pressing parts 391 can be plate-shaped. The plate-shaped pressing parts 391 can form a larger range of contact with the temperature sensing parts 40 to ensure that the two are tightly and firmly attached.

[0363] Specifically, the fastening structure can be used to securely connect the pressing member 391 and the temperature sensing member 40. This application does not specifically limit the connection method of the fastening structure. For example, the connection method can be a snap-fit ​​connection or a threaded connection, etc.

[0364] Thus, the fixing component 390 can apply a force to the temperature sensing element 40, allowing the temperature sensing surface 410 of the temperature sensing element 40 to fit tightly against at least a portion of the burner head 30, thereby enabling the temperature of the burner head 30 to be sensed through the temperature sensing element 40. Furthermore, based on the arrangement of the pressing member 391 and the fastening structure, situations where the temperature sensing surface 410 of the temperature sensing element 40 is not tightly fitted to the burner head 30, or even detached, can be avoided, effectively improving the accuracy and reliability of temperature sensing.

[0365] In some embodiments, see Figure 51 The fastening structure includes a fastener 331, which passes through the pressure member 391. Thus, by connecting the pressure member 391 to at least a portion of the burner head 30 via the fastener 331, the temperature sensing element 40 can be quickly and conveniently installed on at least a portion of the burner head 30, effectively saving installation time and costs. Furthermore, when it is necessary to replace or maintain the temperature sensing element 40, it can be easily disassembled and assembled, greatly reducing the workload and costs required for disassembling and assembling the temperature sensing element 40.

[0366] Specifically, the fastener 331 can be a bolt or screw, etc. The temperature sensing element 40 can be provided with a through hole 423, and the pressing element 391 can be provided with a connecting hole 3911a. In the embodiment where at least part of the burner head 30 is a bracket 310, the bracket 310 can be provided with a mating hole 3117. The fastener 331 can pass through the connecting hole 3911a, the through hole 423 and the mating hole 3117 in sequence, so that the fastener 331 applies force to the pressing element 391, so that the pressing element 391 presses against the temperature sensing element 40 and firmly fixes the temperature sensing element 40 to at least part of the burner head 30.

[0367] In some embodiments, in conjunction with reference Figures 57 to 61 The fastening structure may further include a snap-fit ​​portion 392, which bends and extends from the pressure member 391 toward the temperature-sensing surface 410 to extend through at least a portion of the burner head 30. Thus, the snap-fit ​​portion 392 securely connects the pressure member 391 to at least a portion of the burner head 30 without requiring additional fixing structures, effectively simplifying the connection structure and improving installation convenience. Furthermore, the integral molding design between the snap-fit ​​portion 392 and the pressure member 391 effectively reduces the manufacturing difficulty and cost of the pressure member 391.

[0368] It should be noted that, although Figures 57 to 61 The embodiment shown includes both fastener 331 and snap-fit ​​portion 392 in the fastening structure. However, in the embodiment not shown, the fastening structure may also be either fastener 331 or snap-fit ​​portion 392.

[0369] See again Figure 59 At least a portion of the burner head 30 may have a snap-fit ​​hole 3118 adapted to the snap-fit ​​portion 392. The snap-fit ​​portion 392 may be bent from the pressing member 391 toward the temperature sensing surface 410 to pass through the snap-fit ​​hole 3118, thereby realizing the connection between the pressing member 391 and at least a portion of the burner head 30.

[0370] See Figure 59 The snap-fit ​​part 392 can be plate-shaped. The plate-shaped snap-fit ​​part 392 can not only ensure that there is sufficient snap-fit ​​area between it and at least part of the burner head 30, but also simplify the structure of the snap-fit ​​part 392 and reduce the manufacturing difficulty and manufacturing cost of the snap-fit ​​part 392.

[0371] Furthermore, after the snap-fit ​​portion 392 passes through the snap-fit ​​hole 3118, the end of the snap-fit ​​portion 392 away from the pressing member 391 can be folded back towards at least a portion of the burner head 30 to abut against at least a portion of the burner head 30, thereby limiting the displacement of the pressing member 391 and further enhancing the connection strength between the pressing member 391 and at least a portion of the burner head 30.

[0372] See again Figure 59 When the fastening structure includes fastener 331 and snap-fit ​​portion 392, the cooperation between fastener 331 and snap-fit ​​portion 392 can further enhance the firmness between the temperature sensing element 40 and at least a portion of the furnace head 30.

[0373] In some embodiments, in conjunction with reference Figures 57 to 61The temperature sensing element 40 has a heat-conducting part 420 and a sensing part 431, with the sensing part 431 connected to one end of the heat-conducting part 420. The pressing member 391 has a first abutting part 3911 and a second abutting part 3912, with the second abutting part 3912 connected to one end of the first abutting part 3911. The first abutting part 3911 abuts against the heat-conducting part 420, and the second abutting part 3912 abuts against the sensing part 431. In this way, the heat-conducting part 420 and the sensing part 431 of the temperature sensing element 40 can be independently set and have different functions. While ensuring that the temperature sensing element 40 can sense at least part of the temperature of the burner head 30, the structural layout of the temperature sensing element 40 is also optimized. Furthermore, the first abutting part 3911 can apply force to the heat-conducting part 420 of the temperature-sensing element 40, and the second abutting part 3912 can apply force to the sensing part 431 of the temperature-sensing element 40, thereby enabling the pressing part 391 to apply force to the temperature-sensing element 40 evenly, effectively improving reliability and robustness.

[0374] Specifically, the temperature-sensing surface 410 and the opposing surface 440 can be formed on opposite sides of the heat-conducting portion 420, and the through hole 423 can be located on the heat-conducting portion 420 and penetrate through the temperature-sensing surface 410 and the opposing surface 440. The connecting hole 3911a can be provided on the first abutment portion 3911.

[0375] In some embodiments, in conjunction with reference Figures 57 to 61 The first abutment portion 3911 forms a surface contact with the heat-conducting portion 420. This surface contact significantly increases the contact area between the first abutment portion 3911 and the heat-conducting portion 420, allowing the first abutment portion 3911 to apply force evenly to the heat-conducting portion 420. This ensures that the temperature-sensing surface 410 of the heat-conducting portion 420 can closely contact at least a portion of the burner head 30, effectively improving accuracy and reliability.

[0376] Specifically, the first abutting part 3911 can be plate-shaped, and the plate-shaped first abutting part 3911 can abut against the opposite surface 440 of the heat-conducting part 420, thereby achieving surface contact between the two.

[0377] In some embodiments, in conjunction with reference Figures 57 to 61 The second abutment portion 3912 extends from the end of the first abutment portion 3911 in a bent hook shape, and the end of the second abutment portion 3912 away from the first abutment portion 3911 abuts against the sensing portion 431. In this way, the hook-shaped second abutment portion 3912 can not only avoid the sensing portion 431 of the temperature sensing element 40, thus preventing interference between the two, but also allow the second abutment portion 3912 to better apply force to the sensing portion 431, further improving the firmness of the temperature sensing element 40.

[0378] Specifically, the second abutment portion 3912 can be configured as a hook shape. When the first abutment portion 3911 forms a surface contact with the heat-conducting portion 420, the end of the second abutment portion 3912 away from the first abutment portion 3911 can form a certain angle with the plane where the first abutment surface is located. In this way, the second abutment portion 3912 can apply a force to the sensing portion 431 along a direction that is not parallel to the length of the sensing portion 431.

[0379] In some embodiments, in conjunction with reference Figures 57 to 61 The end of the second abutment portion 3912 furthest from the first abutment portion 3911 forms a line contact or surface contact with the sensing portion 431. In this way, by means of line contact or surface contact, a force can be applied to the sensing portion 431 of the temperature sensing element 40, so as to avoid displacement or even loosening of the temperature sensing element 40 during use, effectively improving reliability and stability.

[0380] Specifically, the end of the second abutment portion 3912 furthest from the first abutment portion 3911 can form a line contact with the sensing portion 431. The line contact can reduce the material used in the second abutment portion 3912, thereby effectively reducing manufacturing costs. Furthermore, the line contact can also have good adaptability to accommodate sensing portions 431 of different shapes.

[0381] Specifically, the end of the second abutment 3912 away from the first abutment 3911 can form a surface contact with the sensing part 431. The surface contact can increase the contact area between the second abutment 3912 and the sensing part 431, so as to apply force to the sensing part 431 more evenly and effectively avoid deformation or damage to the sensing element due to local pressure concentration.

[0382] In some embodiments, in conjunction with reference Figures 57 to 61 The second abutment portion 3912 surrounds and forms a receiving cavity 3913 with an opening 120 at one end. At least a portion of the sensing portion 431 is located within the receiving cavity 3913 through the opening 120. In this way, the receiving cavity 3913 can be used to accommodate at least a portion of the sensing portion 431, optimizing the connection structure and layout, thereby ensuring miniaturization and improving practicality.

[0383] See also Figures 56 to 61 In an embodiment where at least a portion of the burner head 30 is a support 310, the snap-fit ​​portion 392 extends from the end of the first abutment portion 3911 away from the second abutment portion 3912 toward the temperature-sensing surface 410. The snap-fit ​​portion 392 has a height H1, the heat-conducting portion 420 has a first thickness h1, and the support 310 has a second thickness h, where H > h1 + h. Thus, the snap-fit ​​portion 392, having a height range of H1, allows it to penetrate the surface of at least a portion of the burner head 30, effectively improving the strength of the connection between the two, further enhancing practicality and reliability.

[0384] The bracket 310 may have a plate-shaped body 311 that abuts against the heat-conducting part 420. The thickness of the plate-shaped body 311 may be h. When the heat-conducting part 420 of the heat-sensing element 40 is attached to at least a portion of the plate-shaped body 311 of the burner head 30, and the heat-sensing element 40 is fixed to at least a portion of the burner head 30 by the fixing assembly 390, it can be understood that the heat-conducting part 420 is located between the plate-shaped body 311 and the first abutting part 3911. The snap-fit ​​part 392 may have a height H1 greater than the sum of the thickness h1 of the heat-conducting part 420 and the thickness h of the plate-shaped body 311, so that the snap-fit ​​part 392 can pass through at least a portion of the plate-shaped body 311 of the burner head 30.

[0385] In some embodiments, see Figure 56 The heat-conducting part 420 is constructed as a sheet. In this way, the sheet-like structure of the heat-conducting part 420 can not only reduce the volume of the heat-conducting part 420 and reduce the overall weight of the temperature sensing element 40, but also have a large contact area with at least a part of the surface of the burner head 30, effectively ensuring heat transfer and improving the heat conduction efficiency of the heat-conducting part 420.
