Description

TECHNICAL FIELD

[0001] The utility model relates to the technical field of the range, specifically, a burner, a range. BACKGROUND

[0002] With the use rate of gas range being higher and higher, people's requirement for the safety of the range is also higher and higher. The existing gas range is usually provided with a temperature sensing probe to detect the temperature of the pot, and whether the burner is dry burning, accidental extinguishing or the like is judged according to the detected temperature, so that when these situations occur, the gas source can be cut off in the first time to avoid safety hazards.

[0003] At present, most of the gas ranges on the market detect the temperature of the bottom of the pot by contacting the bottom of the pot with an external temperature sensing probe, and when the temperature of the bottom of the pot exceeds the preset temperature, it will automatically extinguish to protect; at the same time, when the range accidentally extinguishes and the pot is not placed for a long time, the gas source can also be cut off in the first time based on the detection result of the external temperature sensing probe to avoid accidents. However, the external temperature sensing probe has certain limitations in use, such as: because the external temperature sensing probe needs to contact the bottom of the pot, in order to avoid interference with the external temperature sensing probe, only flat-bottomed pots can be used for cooking; in addition, the external temperature sensing probe is easily affected by the flame, so that the external temperature sensing probe cannot accurately detect the temperature of the bottom of the pot, causing the range to abnormally determine the extinguishing condition. SUMMARY

[0004] In order to at least partially solve the problems existing in the prior art, according to one aspect of the utility model, a burner is provided, and the technical scheme is as follows.

[0005] The burner comprises an inner ring ejection pipe, an outer ring ejection pipe, a support and a temperature sensing piece, the inner ring ejection pipe and the outer ring ejection pipe are positioned by the support, and the inner ring ejection pipe and the outer ring ejection pipe are spaced apart in a first direction, at least part of the temperature sensing piece forms a surface contact with the support, the position of the surface contact is located between the inner ring ejection pipe and the outer ring ejection pipe, and the first direction is the length direction of the support.

[0006] The burner of the utility model, at least part of the temperature sensing piece forms a surface contact with the support for positioning the inner ring ejection pipe and the outer ring ejection pipe, when the burner is used on the gas range, because the temperature of the support 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 support through the temperature sensing piece (i.e. indirectly detecting the temperature of the pot), the temperature sensing piece will not be affected by the flame, not only ensuring the accuracy and rapidity of temperature detection; and even in the case of using a pointed-bottomed pot, the temperature sensing piece will not interfere with the pot, expanding the application range of the range.

[0007] Exemplarily, in the first direction, the position where the surface contact is located has a first distance x1 from the center of the inner ring ejector pipe, and has a second distance x2 from the center of the outer ring ejector pipe, 0.5x2≤x1≤x2. When the first distance x1 and the second distance x2 have this relationship, the accuracy and rapidity of temperature detection are effectively ensured.

[0008] Exemplarily, in the width direction of the bracket, the position where the surface contact is located has a third distance y1 from the center of the inner ring ejector pipe, 0mm≤y1≤10mm. When the third distance y1 is set in this range, the accuracy and rapidity of temperature detection are effectively ensured.

[0009] Exemplarily, in the width direction of the bracket, the position where the surface contact is located has a fourth distance y2 from the center of the outer ring ejector pipe, 0mm≤y2≤10mm. When the fourth distance y2 is set in this range, the accuracy and rapidity of temperature detection are effectively ensured.

[0010] Exemplarily, the inner ring ejector pipe has an inner ring top end, and the inner ring top end has a first spacing z1 from the position where the surface contact is located in a second direction, the first spacing z1 being 10mm-25mm, and the second direction being perpendicular to the first direction. When the first spacing z1 is set in this range, the accuracy and rapidity of temperature detection are effectively ensured.

[0011] Exemplarily, the outer ring ejector pipe has an outer ring top end, and the outer ring top end has a second spacing z2 from the position where the surface contact is located in the second direction, the second spacing z2 being 8mm-15mm, and the second direction being perpendicular to the first direction. When the second spacing z2 is set in this range, the accuracy and rapidity of temperature detection are effectively ensured.

[0012] Exemplarily, the bracket has a plate-shaped body and a leg, the inner ring ejector pipe is arranged in the plate-shaped body, the outer ring ejector pipe is arranged in the plate-shaped body, one end of the leg is arranged on the plate-shaped body, and the other end of the leg away from the plate-shaped body forms a connecting end. In this way, not only is it convenient to position the inner ring ejector pipe and the outer ring ejector pipe, but also the bracket structure is simple and convenient to install and fix the bracket.

[0013] Exemplarily, in the length direction of the bracket, the left and right sides of the plate-shaped body are respectively bent to form legs, and the position where the surface contact is located is on the plate-shaped body. In this way, it is convenient to process the legs, and it is convenient for the temperature-sensing element to form surface contact with the bracket. Since in the case of heating with a pot on the stove, the temperature of the bottom of the pot above the burner is transmitted to the plate-shaped body through the inner ring ejector pipe and the outer ring ejector pipe, the temperature of the plate-shaped body is associated with the temperature of the bottom of the pot, and the accuracy and rapidity of temperature detection are ensured.

[0014] For example, the plate-shaped body has a surface to be measured, and the temperature sensing element has a contact plane that is in contact with the surface to be measured. In this way, by the contact plane being in contact with the surface to be measured, surface contact is ensured between the temperature sensing element and the support.

[0015] For example, in the width direction of the bracket, the front side and / or the rear side of the plate-shaped body are bent to form a support leg, with the surface contact location situated on the support leg. This facilitates the fabrication of the support leg and allows for full utilization of the internal space of the stove when the burner is used on a gas stove.

[0016] For example, the support leg has a surface to be measured, and the temperature sensing element has a contact plane that is in contact with the surface to be measured. In this way, by the contact plane being in contact with the surface to be measured, surface contact is ensured between the temperature sensing element and the support leg.

[0017] According to another aspect of this utility model, a burner is provided, including a flame distribution seat, a flame cap, and a burner head as described above. The flame cap and the flame distribution seat enclose a mixing chamber, which is connected to an inner ring ejector tube and an outer ring ejector tube. Since the burner head described above has the aforementioned beneficial effects, the burner including the burner head described above also has the aforementioned beneficial effects, which will not be elaborated further here.

[0018] According to another aspect of this utility model, a stove is provided, including a bottom shell, a panel, and a burner as described above. The bottom shell forms an installation cavity with an opening, the panel covers the opening, and the panel has a through hole through which the burner passes, with part of the burner located inside the installation cavity and part of the burner located outside the installation cavity. Since the burner described above has the aforementioned beneficial effects, the stove including the burner described above also has the aforementioned beneficial effects, which will not be elaborated further here.

[0019] This utility model description introduces a series of simplified concepts, which will be further explained in detail in the detailed description section. This utility model description is not intended to limit the key features and essential technical features of the claimed technical solution, nor is it intended to determine the scope of protection of the claimed technical solution.

[0031] 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.

[0032] 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.

[0033] An embodiment of this utility model provides a burner head. The burner head provided by this utility model can be applied to a burner, which can be applied to a gas stove. The following will describe in detail a burner head according to an embodiment of this utility model with reference to the accompanying drawings.

[0034] To gain a comprehensive understanding of this invention, the burner that works in conjunction with the furnace head will be described first.

[0035] Household burners typically consist of two main parts: a burner cap and a flame distribution base, allowing for diverse flame patterns. The burner cap can include an outer ring burner cap and an inner ring burner cap. The outer ring burner cap is located at the outermost layer of the burner, providing a wide heating area. The inner ring burner cap is located inside the outer ring burner cap, forming the central flame area for concentrated heating, and together with the outer ring burner cap, forming at least two rings of flame. The corresponding flame distribution base can include a large flame distribution base and a small flame distribution base. The outer ring burner cap can be placed on the large flame distribution base, and the inner ring burner cap can be placed on the small flame distribution base. The burner may also include a pot support. The pot support can be positioned around the outer ring burner cap. The cookware can be placed on the pot support. When the user turns on the burner, the combustible gas ejected from the flame distribution base is ignited by the ignition needle to form a flame. The flame can diffuse through the gaps in the burner cap to form a flame ring, thereby heating the cookware.

[0036] See also Figures 2 to 7 The burner head 10 may include an inner ring ejector tube 110, an outer ring ejector tube 120, a bracket 130, and a temperature sensing element 140. Both the inner ring ejector tube 110 and the outer ring ejector tube 120 can be positioned by the bracket 130, and the inner ring ejector tube 110 and the outer ring ejector tube 120 may be spaced apart in a first direction. At least a portion of the temperature sensing element 140 can form surface contact with the bracket 130. The surface contact location can be between the inner ring ejector tube 110 and the outer ring ejector tube 120. The first direction can be the length direction of the bracket 130 (i.e., the direction of its length). Figure 2 (in the X direction).

[0037] It should be understood that in this embodiment of the invention, the temperature sensing element 140 indirectly detects the temperature of the pot bottom by detecting the temperature of the support 130. To ensure the accuracy of temperature detection, the support 130 can be made of a thermally conductive material, such as metal or other materials with good thermal conductivity. The inner ring ejector tube 110 and the outer ring ejector tube 120 can also be made of a thermally conductive material, such as metal or other materials with good thermal conductivity. The support 130, the inner ring ejector tube 110, and the outer ring ejector tube 120 can be made of the same material, such as stainless steel, thus forming a stainless steel assembly.

[0038] In this invention, at least a portion of the temperature sensing element 140 of the burner head 10 forms surface contact with the bracket 130 of the inner ring ejector tube 110 and the outer ring ejector tube 120. When the burner head 10 is used on a gas stove, since the temperature of the bracket 130 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 130 through the temperature sensing element 140 (i.e., indirectly detecting the temperature of the pot). The temperature sensing element 140 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 140 will not interfere with the pot even when using a pointed-bottom pot, thus expanding the applicability of the stove.

[0039] See also Figure 2 and Figure 3 In the first direction, the location of the surface contact tube 110 can have a first distance x1 from the center of the inner ring ejector tube 110. The location of the surface contact tube 120 can have a second distance x2 from the center of the outer ring ejector tube 120, where 0.5x2 ≤ x1 ≤ x2. For example, 0.5x2 = x1, 0.7x2 = x1, x2 = x1, etc. When the first distance x1 and the second 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.

[0040] See again Figure 2 and Figure 3 In the width direction of bracket 130 (i.e. Figure 2 In the Y direction (as shown in the diagram), the position of the surface contact and the center of the inner ring ejector tube 110 can have a third distance y1, where 0mm ≤ y1 ≤ 10mm. For example, the third distance y1 can be 0mm, 5mm, 10mm, etc. Setting the third distance y1 within this range effectively ensures the accuracy and speed of temperature detection. In one embodiment of this utility model, the third distance y1 can be 6mm, which further ensures the accuracy and speed of temperature detection.

[0041] In an embodiment not shown, in the width direction of the support 130 (i.e. Figure 2 In the Y direction, the surface contact position can be located behind the center of the inner ring ejector tube 110.

[0042] For example, in conjunction with reference Figure 2 and Figure 3 In the width direction of bracket 130 (i.e. Figure 2 In the Y direction, the surface contact position can be located in front of the center of the inner ring ejector tube 110.

[0043] See again Figure 2 and Figure 3 In the width direction of bracket 130 (i.e. Figure 2 In the Y direction (as shown in the diagram), the position of the surface contact and the center of the outer ring ejector tube 120 can have a fourth distance y2, where 0mm ≤ y2 ≤ 10mm. For example, the fourth distance y2 can be 0mm, 5mm, 10mm, etc. Setting the fourth distance y2 within this range effectively ensures the accuracy and speed of temperature detection. In one embodiment of this utility model, the fourth distance y2 can be 6mm, which further ensures the accuracy and speed of temperature detection.

[0044] In an embodiment not shown, in the width direction of the support 130 (i.e. Figure 2 In the Y direction, the surface contact position can be located behind the center of the outer ring ejector tube 120.

[0045] For example, in conjunction with reference Figure 2 and Figure 3 In the width direction of bracket 130 (i.e. Figure 2 In the Y direction, the surface contact position can be located in front of the center of the outer ring ejector tube 120.

[0046] See Figure 4 The inner ring ejector tube 110 may have an inner ring tip 111. The location where the inner ring tip 111 contacts the surface may have a first spacing z1 in a second direction. The first spacing z1 may be 10mm to 25mm. For example, the first spacing z1 may be 10mm, 17mm, 25mm, etc. The second direction may be perpendicular to the first direction. Understandably, the second direction may be the height direction of the support 130 (i.e.,...). Figure 4 (in the Z direction). The first spacing z1 is set within this range, effectively ensuring the accuracy and speed of temperature detection. In one embodiment of this utility model, the first spacing z1 is 20mm, which further ensures the accuracy and speed of temperature detection.

[0047] See again Figure 4The outer ring ejector tube 120 may have an outer ring tip 121. The location where the outer ring tip 121 contacts the surface may have a second spacing z2 in a second direction. The second spacing z2 may be 8mm to 15mm. For example, the first spacing z1 may be 10mm, 17mm, 25mm, etc. The second direction may be perpendicular to the first direction. Understandably, the second direction may be the height direction of the support 130 (i.e.,...). Figure 4 (in the Z direction). The second spacing z2 is set within this range, effectively ensuring the accuracy and speed of temperature detection. In one embodiment of this utility model, the second spacing z2 is 10mm, which further ensures the accuracy and speed of temperature detection.

[0048] See also Figures 2 to 6 The support 130 may have a plate-shaped body 131 and a foot 132. An inner ring ejector tube 110 may pass through the plate-shaped body 131. An outer ring ejector tube 120 may pass through the plate-shaped body 131. One end of the foot 132 may be disposed on the plate-shaped body 131. The end of the foot 132 away from the plate-shaped body 131 may form a connecting end 1321. (See reference...) Figure 1 When the burner head 10 is used on a gas stove, the connecting end 1321 can be connected to the bottom shell 3 to install and fix the bracket 130. In this way, it is not only easy to position the inner ring injector 110 and the outer ring injector 120, but the bracket 130 has a simple structure and is easy to install and fix.

[0049] In some embodiments, in the longitudinal direction of the bracket 130 (i.e. Figure 2 In the X direction (as shown in the diagram), the left and right sides of the plate-shaped body 131 can be bent to form supports 132. In an embodiment not shown, in the width direction of the support 130 (i.e., ... Figure 2 In the Y direction, the front and rear sides of the plate-shaped body 131 can be bent to form support legs 132. The surface contact position can be located on the plate-shaped body 131. In this way, it is convenient to process and form the support legs 132, and at the same time, it is convenient for the temperature sensing element 140 to form surface contact with the support 130. In addition, when the pot is heated, the temperature of the pot bottom above the burner 10 is transferred to the plate-shaped body 131 through the inner ring ejector tube 110 and the outer ring ejector tube 120. Thus, the temperature of the plate-shaped body 131 is correlated with the temperature of the pot bottom, ensuring the accuracy and speed of temperature detection.

[0050] Specifically, the plate-shaped body 131 may have a surface to be measured 133. The temperature sensing element 140 may have a contact plane 141. The contact plane 141 may be in contact with the surface to be measured 133. In this way, by the contact plane 141 being in contact with the surface to be measured 133, the temperature sensing element 140 and the support 130 are in surface contact.

[0051] For example, seeFigure 5 The surface to be measured 133 can be a part of the upper surface of the plate-shaped body 131. Understandably, the temperature sensing element 140 is entirely disposed above the plate-shaped body 131, that is, the temperature sensing element 140 is disposed on the side of the plate-shaped body 131 closer to the operator. This facilitates the installation of the temperature sensing element 140 and ensures that the temperature sensing element 140 forms surface contact with the support 130.

[0052] For example, in conjunction with reference Figure 2 , Figure 3 , Figure 4 and Figure 6 The surface to be measured 133 can be a portion of the lower surface of the plate-shaped body 131. Understandably, the temperature sensing element 140 is entirely disposed below the plate-shaped body 131, that is, the temperature sensing element 140 is disposed on the side of the plate-shaped body 131 furthest 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 140 is hidden below the plate-shaped body 131, effectively preventing leaked soup or liquid from contacting the temperature sensing element 140 and affecting its detection accuracy and service life.

[0053] In an embodiment not shown, the surface contact point can be located on the support leg 132. This allows for full utilization of the internal space of the cooktop when the burner head 10 is used on a gas stove.

[0054] Specifically, the support leg 132 may have a test surface 133, and the temperature sensing element 140 has a contact plane 141, which is in contact with the test surface 133. In this way, by the contact plane 141 being in contact with the test surface 133, the temperature sensing element 140 and the support leg 132 are in surface contact.

[0055] For example, in the width direction of the bracket 130 (i.e. Figure 2 In the Y direction, the front and rear sides of the plate-shaped body 131 can be bent to form supports 132. This facilitates the processing and formation of the supports 132. The surface to be measured 133 can be located on the support 132 on the front side of the plate-shaped body. The surface to be measured 133 can be a part of the inner side of the support 132 near the plate-shaped body 131.

[0056] For example, in the width direction of the bracket 130 (i.e. Figure 2 In the Y direction, the front and rear sides of the plate-shaped body 131 can be bent to form supports 132. This facilitates the processing and formation of the supports 132. The measured surface 133 can be located on the support 132 on the front side of the plate-shaped body. The measured surface 133 can be a part of the outer side of the support 132 away from the plate-shaped body 131.

[0057] For example, in the width direction of the bracket 130 (i.e. Figure 2In the Y direction, the front and rear sides of the plate-shaped body 131 can be bent to form supports 132. This facilitates the processing and formation of the supports 132. The surface to be measured 133 can be located on the support 132 on the rear side of the plate-shaped body. The surface to be measured 133 can be a part of the inner side of the support 132 near the plate-shaped body 131.

[0058] For example, in the width direction of the bracket 130 (i.e. Figure 2 In the Y direction, the front and rear sides of the plate-shaped body 131 can be bent to form supports 132. This facilitates the processing and formation of the supports 132. The measured surface 133 can be located on the support 132 on the rear side of the plate-shaped body. The measured surface 133 can be a part of the outer side of the support 132 away from the plate-shaped body 131.

[0059] In an embodiment not shown, the support 130 may have a protrusion extending beyond the outer side of the plate-like body 131 or the outer side of the support leg 132. A temperature sensing element 140 may be disposed on the protrusion. Specifically, the protrusion may enclose a receiving cavity with an inner opening. At least a portion of the inner wall surface of the receiving cavity may be configured as the surface to be measured 133; or, at least a portion of the outer wall surface of the receiving cavity may be configured as the surface to be measured 133.

[0060] In an embodiment not shown, the support 130 may have a recessed groove recessed into the inner side of the plate-like body 131 or the inner side of the support leg 132. A temperature sensing element 140 may be disposed in the recessed groove. Specifically, at least a portion of the inner wall of the recessed groove may be configured as the surface to be measured 133; or, at least a portion of the outer wall of the recessed groove may be configured as the surface to be measured 133.

[0061] Specifically, in conjunction with reference Figures 2 to 7 The temperature sensing element 140 may have a sheet-like portion 142. A contact plane 141 may be formed on the sheet-like portion 142. This facilitates surface contact between the temperature sensing element 140 and the bracket 130, ensuring the accuracy and speed of temperature detection. Furthermore, the sheet-like portion 142 makes it easier to install the temperature sensing element 140.

[0062] In the above embodiments, the sheet-like portion 142 can be tightly fitted to the surface 133 to be measured by fasteners 150. This ensures the stability of the connection between the temperature sensing element 140 and the support 130, and also guarantees good surface contact. Specifically, a first mounting hole (not marked in the figure) can be provided on the surface 133 to be measured. A second mounting hole 1421 can be provided on the sheet-like portion 142. Fasteners 150 pass through the first mounting hole and the second mounting hole 1421 in sequence to fix the sheet-like portion 142 to the plate-like body 131. Fasteners 150 can be screws, bolts, etc. In embodiments not shown, the temperature sensing element 140 can also be connected to the support 130 by other means, such as welding, riveting, gluing, or snap-fit ​​connection.

[0063] It should be noted that the location of the surface contact is positioned with respect to the center of the contact plane 141. When a second mounting hole 1421 is provided on the sheet-like portion 142, the center of the contact plane 141 is the center of the second mounting hole 1421. In some embodiments, refer to... Figure 2 and Figure 4 The first mounting hole and the second mounting hole 1421 can be concentric, so the axis of the fastener 150 can also be concentric with the first mounting hole and the second mounting hole 1421. At this time, the position of the surface contact can be the position of the axis of the fastener 150.

[0064] In some embodiments, the sheet-like portion 142 may have an alloy material layer and an electroplated layer. The electroplated layer may be formed on the surface of the alloy material layer, and a contact plane 141 may be formed on the outer surface of the electroplated layer away from the alloy material layer. This further improves the accuracy of temperature detection, and the electroplated layer also prevents the sheet-like portion 142 from rusting, thereby extending the service life of the temperature sensing element 140. Specifically, the alloy material layer may be made of copper. Copper has excellent thermal conductivity, being the second best thermally conductive material among pure metals. The electroplated layer may be made of nickel. Nickel not only has good thermal conductivity but also good thermal stability, effectively protecting the alloy material layer and preventing the sheet-like portion 142 from rusting. Of course, the alloy material layer and the electroplated layer may also be made of other materials.

[0065] See also Figures 2 to 7 The temperature sensing element 140 may have a sheet-like portion 142 and a lead portion 143. The lead portion 143 may include a probe body 1431 connected to the sheet-like portion 142. The probe body 1431 may contain a device (hereinafter referred to as a conversion device) that can convert temperature information into other output or identifiable signals, such as a temperature sensor. Specifically, this device may be a negative temperature coefficient thermistor. Under normal heating conditions, the temperature change rate of a negative temperature coefficient thermistor is relatively stable. However, when the cookware becomes dry-burned, due to insufficient medium to absorb heat, the temperature of the cookware rises rapidly, and the temperature of the support 130 also rises rapidly, causing a sharp increase in the temperature change rate of the negative temperature coefficient thermistor.

[0066] Negative temperature coefficient (NTC) thermistors exhibit a temperature-resistance characteristic curve. When the temperature of an NTC thermistor increases, the slope of its temperature-resistance characteristic curve increases, indicating that the NTC thermistor is under continuous heating, and thus confirming that the cookware is in a dry-burning state. NTC thermistors have a fast response time and high sensitivity to temperature changes, providing accurate temperature measurements. Furthermore, NTC thermistors have a simple structure, low cost, low failure rate, and good long-term stability. Their high heat transfer efficiency allows for a sensitive response to temperature changes, and their simple structure and low operating cost effectively reduce the failure rate and operating cost of burner 1, improving its reliability.

[0067] In some embodiments, the probe body 1431 may contain a thermally conductive medium. This allows the temperature of the support 130 to be transferred to the conversion device more effectively and precisely, thereby further improving the accuracy and speed of temperature detection. Specifically, the thermally conductive medium can be a thermally conductive resin. Thermally conductive resin not only has high thermal conductivity but also stability. Filling the probe body 1431 with thermally conductive resin can effectively improve the accuracy and speed of temperature detection. Of course, the thermally conductive medium can also be other materials.

[0068] Furthermore, in conjunction with reference Figure 2 , Figure 3 , Figure 5 , Figure 6 and Figure 7 The lead portion 143 may further include a signal transmission line 1432 connected to the end of the probe body 1431 away from the sheet portion 142. This not only facilitates the transmission of the output signal converted from the temperature information collected by the temperature sensing element 140, but also prevents high temperatures from affecting the signal transmission line 1432, as the signal transmission line 1432 is relatively far from the sheet portion 142. Specifically, the signal transmission line 1432 may be covered with a protective sleeve. The protective sleeve further prevents high temperatures from affecting the signal transmission line 1432 and also avoids the problem of the signal transmission line 1432 being easily damaged when exposed.

[0069] Specifically, the inner ring ejector tube 110 and the outer ring ejector tube 120 may have an ejector body 101. The ejector body 101 may be connected to a gas pipe (not shown in the figure). Combustible gas can enter the ejector body 101 through the gas pipe, and then be ejected from the ends of the inner ring ejector tube 110 and the outer ring ejector tube 120 away from the gas pipe, and finally ignited by an ignition needle to form a flame. The lead wire portion 143 may be connected to the end of the plate-shaped portion 142 away from the ejector body 101. In this way, the influence of the heat generated by combustion near the inner ring ejector tube 110 and the outer ring ejector tube 120 on the lead wire portion 143 is reduced, the lead wire portion 143 is protected, the service life of the temperature sensing element 140 is extended, and the accuracy of the temperature sensing element 140 is guaranteed.

[0070] In an embodiment not shown, the end of the signal transmission line 1432 furthest from the probe body 1431 can be connected to a controller. The temperature information collected by the plate-shaped portion 142 of the temperature sensing element 140 is converted into a signal by the conversion device and transmitted to the controller via the signal transmission line 1432. The controller can control the operating state of the burner 1 based on this signal. When the controller determines, based on this signal, that the burner 1 is in a state of dry burning of the cookware, accidental flameout, or prolonged high flame without placing the cookware on it, it can immediately cut off the gas supply to extinguish the burner 1 and avoid safety hazards.

[0071] In the above embodiments, the temperature sensing element 140 is tightly fitted to the surface to be measured 133 via the sheet-like portion 142 to form surface contact. In embodiments not shown, the sheet-like portion 142 can be replaced by a wire. The wire can be disposed on the surface to be measured 133 and form line contact with the support 130. It should be understood that surface contact enhances the connection stability between the temperature sensing element 140 and the support 130 compared to line contact. Specifically, refer to... Figure 5 and Figure 6 When the surface to be tested 133 is disposed on the plate-shaped body 131, the linear body can form line contact with either the upper or lower surface of the plate-shaped body 131. In an embodiment not shown, when the surface to be tested 133 is disposed on the support leg 132, the linear body can form line contact with either the inner surface of the support leg 132 located on the front side of the plate-shaped body 131 or the inner surface of the support leg 132 located on the front side of the plate-shaped body 131.

[0072] According to another aspect of this utility model, a burner 1 is provided, including a flame distribution seat 20, a flame cap 30, and a burner head 10 as described above. The flame cap 30 and the flame distribution seat 20 can be closed to form a mixing chamber 40. The mixing chamber 40 can be connected to an inner ring ejector tube 110 and an outer ring ejector tube 120. Since the burner head 10 described above has the aforementioned beneficial effects, the burner 1 including the burner head 10 described above also has the aforementioned beneficial effects, which will not be elaborated further here.

[0073] According to another aspect of the present invention, a stove is provided, including a bottom shell 3, a panel 2, and a burner 1 as described above. The bottom shell 3 can form a mounting cavity with an opening. The panel 2 can cover the opening. The panel 2 can be provided with a through hole. The burner 1 can pass through the through hole, with part of the burner 1 located inside the mounting cavity and part of the burner 1 located outside the mounting cavity. Since the burner 1 described above has the aforementioned beneficial effects, the stove including the burner 1 described above also has the aforementioned beneficial effects, which will not be elaborated further here.
