Description

Technical Field

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

[0002] As the usage rate of gas stoves increases, people's requirements for stove safety are also rising. Existing gas stoves are usually equipped with temperature sensors to detect the temperature of the pots and pans, and to determine whether there are situations such as burner dry burning or accidental flameout based on the detected temperature. In such cases, the 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 burner head is provided, the technical solution of which is as follows.

[0005] The burner head includes a support, an ejector tube, and a temperature sensing element. The ejector tube is positioned by the support, and the temperature sensing element is mounted on the support, with at least a portion of the temperature sensing element in contact with the support.

[0006] In this invention, at least a portion of the temperature sensing element of the burner head contacts the bracket of the positioning ejector tube. When the burner head is used on a gas stove, since the temperature of the bracket 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 through the temperature sensing element (i.e., indirectly detecting the temperature of the pot). 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 pot even when using a pointed-bottom pot, thus expanding the applicability of the stove.

[0007] For example, at least a portion of the temperature sensing element forms line or surface contact with the bracket. This ensures a sufficient contact area between the temperature sensing element and the bracket, thereby guaranteeing the accuracy and speed of temperature detection.

[0008] For example, the bracket 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 bracket.

[0009] For example, the support has a plate-shaped body, through which at least part of the ejector tube passes, and the surface to be measured is disposed on the plate-shaped body. This not only facilitates the positioning of the ejector tube, but also, since the temperature of the pot bottom above the burner 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.

[0010] For example, the plate-shaped body has an upper surface, and the surface to be measured is a part of the upper surface. This facilitates the installation of the temperature sensing element and ensures that the temperature sensing element forms surface contact with the support.

[0011] For example, the plate-shaped body has a lower surface, and the surface to be measured is a part of the lower surface. On the one hand, this avoids the influence of flame combustion on temperature detection, ensuring the accuracy of temperature detection; on the other hand, it effectively prevents leaked soup from contacting the temperature sensing element and affecting the accuracy and service life of the temperature sensing element.

[0012] For example, the plate-shaped body has an upper surface and a protrusion, the protrusion protruding from the upper surface, and the surface to be measured is disposed on the protrusion. In this way, the protrusion can position the temperature sensing element for installation, facilitating the installation and fixation of the temperature sensing element. Moreover, since the protrusion is set on the upper surface, it allows leaked soup to flow down easily, effectively preventing the leaked soup from soaking the temperature sensing element and thus affecting the accuracy and service life of the temperature sensing element.

[0013] For example, the protrusion has a first outer surface, at least a portion of which is configured as the surface to be measured. Thus, the protrusion can position the temperature sensing element for mounting and facilitates the installation and fixation of the temperature sensing element.

[0014] For example, the protrusion has a top wall and a connecting side wall, which together form a receiving cavity with a lower opening. At least a portion of the inner wall surface of the receiving cavity is configured as the surface to be measured. Thus, on the one hand, the protrusion can position the temperature sensing element for installation, facilitating its installation and fixation; on the other hand, the surface to be measured is located within the receiving cavity, which not only better facilitates the stable fixation of the temperature sensing element but also effectively prevents leaked liquid from contacting the surface to be measured, thereby affecting the accuracy and service life of the temperature sensing element. Furthermore, the heat-retaining effect of the receiving cavity further ensures the accuracy of the temperature sensing element's detection.

[0015] For example, the temperature sensing element has a plate-shaped portion and a lead portion connected to the plate-shaped portion. The plate-shaped portion is placed inside the receiving cavity, and the lead portion extends out of the receiving cavity through a lower opening. In this way, the receiving cavity can position the plate-shaped portion for installation, facilitating the installation and fixation of the temperature sensing element, and also making it easy to lead the lead portion out of the receiving cavity. At the same time, since the receiving cavity has a heat-concentrating effect, it further ensures the accuracy of temperature detection by the temperature sensing element.

[0016] For example, the contact plane has an area S1, and the inner wall of the accommodating cavity has an area S2, where S2 / S1 = 1 to 1.5. When there is this relationship between the areas S1 and S2, the sheet-like part can be completely embedded in the accommodating cavity, ensuring that the sheet-like part can completely fit the inner wall surface, thus ensuring the accuracy of temperature detection. At the same time, the accommodating cavity can play a positioning role for the sheet-like part during installation.

[0017] For example, the plate-shaped body has a lower surface and a recessed groove, the recessed groove being recessed below the lower surface, and the surface to be measured is disposed on the recessed groove. In this way, the recessed groove can position the temperature sensing element for installation and facilitates the installation and fixation of the temperature sensing element.

[0018] For example, the recess has a second outer surface, at least a portion of which is configured as the surface to be measured. Thus, the recess can position the temperature sensor for mounting, facilitating its installation and fixation.

[0019] For example, at least a portion of the inner wall of the recessed groove is configured as the surface to be measured. Thus, the recessed groove can be used to position the temperature sensing element, facilitating its installation and fixation. Furthermore, the heat-concentrating effect of the recessed groove further ensures the accuracy of the temperature sensing element's detection.

[0020] For example, the temperature sensing element has a sheet-like portion and a lead portion connected to the sheet-like portion. A side opening is provided on the side wall of the recessed groove. The sheet-like portion is placed inside the recessed groove, and the lead portion extends out of the recessed groove through the side opening. In this way, the recessed groove can position the installation of the sheet-like portion and facilitate the extension of the lead portion out of the recessed groove. At the same time, since the recessed groove has a heat-gathering effect, it further ensures the accuracy of the temperature sensing element.

[0021] For example, the contact plane has an area S1, and the inner wall of the recessed groove has an area S3, where S3 / S1 = 1 to 1.5. When there is this relationship between the areas S1 and S3, the sheet-like part can be completely embedded in the recessed groove, ensuring that the sheet-like part can completely fit the inner wall of the groove, thus ensuring the accuracy of temperature detection. At the same time, the recessed groove can also play a positioning role for the sheet-like part during installation.

[0022] For example, the temperature sensing element has a sheet-like portion on which a contact plane is formed. This facilitates surface contact between the temperature sensing element and the bracket, ensuring the accuracy and speed of temperature detection. Furthermore, the sheet-like portion design makes it easier to install the temperature sensing element.

[0023] For example, the sheet-like portion has a thickness D, which is 0.4 mm to 1 mm. With the thickness D set within this range, the sheet-like portion is more sensitive to temperature changes, ensuring the accuracy and speed of temperature detection by the sheet-like portion.

[0024] For example, the sheet-like portion has an alloy material layer and an electroplated layer, the electroplated layer being formed on the surface of the alloy material layer, and the electroplated layer forming a contact plane away from the outer surface of the alloy material layer. This further improves the accuracy of temperature detection, and the electroplated layer also prevents the sheet-like portion from rusting, thereby extending the service life of the temperature sensing element.

[0025] 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 injector 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.

[0026] 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 a mounting cavity with a mounting opening, the panel covers the mounting opening, and the panel has a through hole through which the burner passes, with part of the burner located inside the mounting cavity and part of the burner located outside the mounting 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.

[0045] 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.

[0046] 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.

[0047] 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.

[0048] To gain a comprehensive understanding of this invention, the burner that works in conjunction with the furnace head will be described first.

[0049] 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.

[0050] See also Figures 2 to 13 The burner head 10 may include a support 110, an ejector tube 120, and a temperature sensing element 130. The ejector tube 120 can be positioned by the support 110. For a dual-ring burner, the ejector tube 120 typically includes an inner ring ejector tube and an outer ring ejector tube, and the support 110 can simultaneously position both the inner and outer ring ejector tubes. The support 110 may be made of a thermally conductive material, such as metal or other materials with good heat transfer properties. The ejector tube 120 may also be made of a thermally conductive material, such as metal or other materials with good heat transfer properties. The support 110 and the ejector tube 120 may be made of the same material, such as stainless steel, thus forming a stainless steel assembly. The temperature sensing element 130 may be mounted on the support 110, and at least a portion of the temperature sensing element 130 may be in contact with the support 110.

[0051] In this invention, at least a portion of the temperature sensing element 130 of the burner head 10 is in contact with the bracket 110 of the positioning ejector tube 120. When the burner head 10 is used on a gas stove, since the temperature of the bracket 110 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 110 through the temperature sensing element 130 (i.e., indirectly detecting the temperature of the pot). The temperature sensing element 130 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 130 will not interfere with the pot even when using a pointed-bottom pot, thus expanding the applicability of the stove.

[0052] It should be understood that in this embodiment of the utility model, the temperature sensing element 130 actually detects the relevant temperature of the bottom of the pot indirectly by detecting the temperature of the bracket 110. In order to ensure the accuracy of temperature detection, the bracket 110 can be made of a material with good thermal conductivity, such as stainless steel.

[0053] In this embodiment of the invention, to ensure the accuracy and speed of temperature detection, at least a portion of the temperature sensing element 130 forms line contact or surface contact with the bracket 110. This ensures the contact area between the temperature sensing element 130 and the bracket 110, thereby guaranteeing the accuracy and speed of temperature detection. It should be understood that surface contact enhances the connection stability between the temperature sensing element 130 and the bracket 110 compared to line contact.

[0054] See also Figure 2 , Figure 5 , Figure 6 , Figure 7 and Figure 8 The bracket 110 may have a surface to be measured 111. The temperature sensing element 130 may have a contact plane 131. The contact plane 131 may be in contact with the surface to be measured 111. In this way, by the contact plane 131 being in contact with the surface to be measured 111, the temperature sensing element 130 and the bracket 110 are in surface contact.

[0055] See again Figures 2 to 12 The support 110 may have a plate-shaped body 112 and a leg 113. One end of the leg 113 may be disposed on the plate-shaped body 112. The end of the leg 113 away from the plate-shaped body 112 may form a connecting end 1131. (See also...) Figure 1 When the burner head 10 is applied to a gas stove, the connecting end 1131 can be fixedly connected to the bottom shell 3 of the stove to secure the burner head 10. The ejector tube 120 can at least partially penetrate the plate-shaped body 112. The surface to be measured 111 can be set on the plate-shaped body 112. This not only facilitates the positioning of the ejector tube 120, but also, since the temperature of the pot bottom above the burner head 10 is transferred to the plate-shaped body 112 through the ejector tube 120 when the pot is heated, the temperature of the plate-shaped body 112 is correlated with the temperature of the pot bottom, ensuring the accuracy and speed of temperature detection. Specifically, the plate-shaped body 112 can be made of a material with good thermal conductivity, such as stainless steel.

[0056] See also Figure 2 , Figure 5 , Figure 6 , Figure 7 , Figure 8 , Figure 9 , Figure 11 , Figure 12 and Figure 13 The temperature sensing element 130 may have a sheet-like portion 132. A contact plane 131 may be formed on the sheet-like portion 132. This ensures that the temperature sensing element 130 forms a surface contact with the bracket 110, guaranteeing the accuracy and speed of temperature detection. Furthermore, the sheet-like portion 132 facilitates the installation of the temperature sensing element 130.

[0057] In some embodiments, the sheet-like portion 132 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 131 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 132 from rusting, thereby extending the service life of the temperature sensing element 130. 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 132 from rusting. Of course, the alloy material layer and the electroplated layer may also be made of other materials.

[0058] See also Figures 5 to 13 The sheet-like portion 132 may have a thickness D, which can be 0.4 mm to 1 mm, such as 0.4 mm, 0.5 mm, or 1 mm. With the thickness D set within this range, the sheet-like portion 132 becomes more sensitive to temperature changes, ensuring the accuracy and speed of temperature detection. In one embodiment of this invention, the thickness D is 0.7 mm, which effectively guarantees the accuracy and speed of temperature detection by the sheet-like portion 132.

[0059] In some embodiments, the temperature sensing element 130 can be directly disposed on the plate-shaped body 112. In this way, the plate-shaped body 112 has a simple structure and is easy to process and manufacture.

[0060] For example, see Figure 5 The plate-shaped body 112 may have an upper surface 1121. The surface to be measured 111 may be a part of the upper surface 1121. Understandably, the temperature sensing element 130 is entirely disposed above the plate-shaped body 112, that is, the temperature sensing element 130 is disposed on the side of the plate-shaped body 112 closer to the operator. This facilitates the installation of the temperature sensing element 130 and ensures that the temperature sensing element 130 forms surface contact with the support 110.

[0061] For example, see Figure 9 The plate-shaped body 112 may have a lower surface 1122. The surface to be measured 111 may be a part of the lower surface 1122. Understandably, the temperature sensing element 130 is entirely disposed below the plate-shaped body 112, that is, the temperature sensing element 130 is disposed on the side of the plate-shaped body 112 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 130 is hidden below the plate-shaped body 112, effectively preventing leaked soup from contacting the temperature sensing element 130 and affecting the accuracy and service life of the temperature sensing element 130.

[0062] In some embodiments, in conjunction with reference Figure 6 , Figure 7 and Figure 8 The plate-shaped body 112 may have an upper surface 1121 and a protrusion 1123. The protrusion 1123 may protrude from the upper surface 1121. The surface to be measured 111 may be disposed on the protrusion 1123. In this way, the protrusion 1123 can position the temperature sensing element 130 for installation, facilitating the installation and fixation of the temperature sensing element 130. Furthermore, since the protrusion 1123 protrudes from the upper surface 1121, it allows leaked soup to flow down easily, effectively preventing the leaked soup from soaking the temperature sensing element 130 and thus affecting the accuracy and service life of the temperature sensing element 130.

[0063] For example, see Figure 6 The protrusion 1123 may have a first outer surface 1123a. At least a portion of the first outer surface 1123a may be configured as the surface to be measured 111.

[0064] Furthermore, the protrusion 1123 may have a top wall 1123b and a connecting side wall 1123c. The top wall 1123b and the connecting side wall 1123c may enclose a receiving cavity 1124 with a lower opening 1126. At least a portion of the inner wall surface of the receiving cavity 1124 may be configured as a test surface 111. Thus, on the one hand, the protrusion 1123 can position the installation of the temperature sensing element 130, facilitating the installation and fixation of the temperature sensing element 130; on the other hand, the test surface 111 is located within the receiving cavity 1124, which not only facilitates the stable fixation of the temperature sensing element 130, but also effectively prevents leaked liquid from contacting the test surface 111, thereby affecting the accuracy and service life of the temperature sensing element 130. At the same time, since the receiving cavity 1124 has a heat-concentrating effect, it further ensures the accuracy of the temperature sensing element 130.

[0065] For example, see Figure 7 The temperature sensing element 130 may have a sheet-like portion 132 and a lead portion 133 connected to the sheet-like portion 132. The sheet-like portion 132 may be placed inside the receiving cavity 1124. The lead portion 133 may extend outside the receiving cavity 1124 through the lower opening 1126. In this way, the receiving cavity 1124 can position the installation of the sheet-like portion 132, which is convenient for installing and fixing the temperature sensing element 130, and also facilitates the extension of the lead portion 133 out of the receiving cavity 1124. At the same time, since the receiving cavity 1124 has a heat-concentrating effect, it further ensures the accuracy of the temperature sensing element 130. Understandably, the figure only shows the case where the sheet-like portion 132 is in contact with the inner wall surface of the top wall 1123b. In an embodiment not shown, the sheet portion 132 may be attached to the inner wall surface of the connecting side wall 1123c, or the sheet portion 132 may be attached to both the inner wall surface of the connecting side wall 1123c and the inner wall surface of the top wall 1123b.

[0066] For example, see Figure 8The temperature sensing element 130 may have a sheet-like portion 132 and a lead portion 133 connected to the sheet-like portion 132. A side opening 1127 may be provided on the connecting side wall 1123c. The sheet-like portion 132 can be placed in the receiving cavity 1124 through the side opening 1127. The lead portion 133 can extend out of the receiving cavity 1124 through the side opening 1127 and be located above the sheet-like portion 132. Thus, the side opening 1127 can be used to position the installation of the sheet-like part 132. Simply align the sheet-like part 132 with the side opening 1127, and then insert the sheet-like part 132 into the receiving cavity 1124 through the side opening 1127 to complete the installation of the temperature sensing element 130. This facilitates the installation and fixation of the temperature sensing element 130. Furthermore, placing the sheet-like part 132 within the receiving cavity 1124 effectively prevents leaked soup from contacting the sheet-like part 132, thereby avoiding any impact on the accuracy and service life of the temperature sensing element 130.

[0067] Specifically, the contact plane 131 may have an area S1. The inner wall surface of the accommodating cavity 1124 may have an area S2. S2 / S1 = 1 to 1.5. For example, S3 / S1 = 1, S3 / S1 = 1.3, S3 / S1 = 1.5, etc. Understandably, the area S1 of the contact plane 131 is the area where the sheet-like portion 132 and the inner wall surface of the accommodating cavity 1124 are in contact. The area S2 of the inner wall surface of the accommodating cavity 1124 is the area of ​​the cavity wall where the sheet-like portion 132 is in contact. When the sheet-like portion 132 is provided on the connecting side wall 1123c, the area S2 is the area of ​​the inner wall surface of the connecting side wall 1123c; when the sheet-like portion 132 is provided on the top wall 1123b, the area S2 is the area of ​​the inner wall surface of the top wall 1123b. When there is this relationship between areas S1 and S2, the sheet-like portion 132 can be completely embedded in the receiving cavity 1124, ensuring that the sheet-like portion 132 can completely conform to the inner wall surface, thus ensuring the accuracy of temperature detection. Simultaneously, the receiving cavity 1124 can position the sheet-like portion 132 during installation. In one embodiment of this invention, S2 / S1 = 1.2, in which case the fitting and fixing effects between the sheet-like portion 132 and the receiving cavity 1124 are even better.

[0068] In some embodiments, in conjunction with reference Figure 10 , Figure 11 and Figure 12 The plate-shaped body 112 may have a lower surface 1122 and a recessed groove 1125. The recessed groove 1125 may be recessed below the lower surface 1122. The surface to be measured 111 is disposed on the recessed groove 1125. In this way, the recessed groove 1125 can position the temperature sensing element 130 for installation and facilitates the installation and fixation of the temperature sensing element 130.

[0069] For example, see Figure 10The recess 1125 may have a second outer surface 1125a. At least a portion of the second outer surface 1125a is configured as the surface to be measured 111. In this way, the recess 1125 can position the temperature sensing element 130 for installation, facilitating the installation and fixation of the temperature sensing element 130.

[0070] Furthermore, the recessed groove 1125 may have a bottom wall 1125c and a side wall 1125b. The bottom wall 1125c and the side wall 1125b can be closed to form the recessed groove 1125. At least a portion of the inner wall surface of the recessed groove 1125 is configured as the surface to be measured 111. In this way, the recessed groove 1125 can be used to position the temperature sensing element 130 for installation, and facilitates the installation and fixation of the temperature sensing element 130. At the same time, since the recessed groove 1125 has a heat-concentrating effect, it further ensures the accuracy of the temperature detection by the temperature sensing element 130.

[0071] For example, see Figure 11 The temperature sensing element 130 may have a sheet-like portion 132 and a lead portion 133 connected to the sheet-like portion 132. The recessed groove 1125 may have an upper opening 1126a. The sheet-like portion 132 can be placed inside the recessed groove 1125 through the upper opening 1126a. The lead portion 133 can extend outside the recessed groove 1125 through the upper opening 1126a. In this way, the recessed groove 1125 can position the installation of the sheet-like portion 132 and facilitate the extension of the lead portion 133 out of the recessed groove 1125. At the same time, since the recessed groove 1125 has a heat-concentrating effect, it further ensures the accuracy of the temperature sensing element 130. Understandably, the figure only shows the case where the sheet-like portion 132 is in contact with the inner wall surface of the bottom wall 1125c of the groove. In an embodiment not shown, the sheet-like portion 132 may be attached to the inner wall surface of the groove sidewall 1125b, or the sheet-like portion 132 may be attached to both the inner wall surface of the groove sidewall 1125b and the inner wall surface of the groove bottom wall 1125c.

[0072] For example, see Figure 12 The temperature sensing element 130 may have a sheet-like portion 132 and a lead portion 133 connected to the sheet-like portion 132. A side opening 1127 may be provided on the groove sidewall 1125b of the recessed groove 1125. The sheet-like portion 132 can be placed inside the recessed groove 1125 through the side opening 1127. The lead portion 133 can extend out of the recessed groove 1125 through the side opening 1127. Thus, the side opening 1127 can be used to position the plate-shaped part 132 for installation. Simply align the plate-shaped part 132 with the side opening 1127, and then insert the plate-shaped part 132 into the recessed groove 1125 through the side opening 1127 to complete the installation of the temperature sensing element 130. This facilitates the installation and fixation of the temperature sensing element 130, and places the lead wire part 133 below the plate-shaped body 112, effectively preventing leaked soup from contacting the lead wire part 133 and thus affecting the accuracy and service life of the temperature sensing element 130.

[0073] Specifically, the contact plane 131 may have an area S1. The inner wall surface of the recessed groove 1125 may have an area S3, where S3 / S1 = 1 to 1.5, for example, S3 / S1 = 1, S3 / S1 = 1.3, S3 / S1 = 1.5, etc. Understandably, the area S1 of the contact plane 131 is the area where the sheet-like portion 132 and the inner wall surface of the recessed groove 1125 are in contact. The area S3 of the inner wall surface of the recessed groove 1125 is the area of ​​the groove wall where the sheet-like portion 132 is in contact. When the sheet-like portion 132 is provided on the groove side wall 1125b, the area S3 is the area of ​​the inner wall surface of the groove side wall 1125b; when the sheet-like portion 132 is provided on the groove bottom wall 1125c, the area S3 is the area of ​​the inner wall surface of the groove bottom wall 1125c. When there is this relationship between areas S1 and S3, the sheet-like portion 132 can be completely embedded in the recessed groove 1125, ensuring that the sheet-like portion 132 can completely conform to the inner wall of the groove, thus ensuring the accuracy of temperature detection. Simultaneously, the recessed groove 1125 can also position the sheet-like portion 132 during installation. In one embodiment of this invention, S3 / S1 = 1.2, in which case the fitting and fixing effects between the sheet-like portion 132 and the recessed groove 1125 are even better.

[0074] In the above embodiments, the sheet-like portion 132 can be tightly fitted to the surface 111 to be measured by fasteners 140. This ensures the stability of the connection between the temperature sensing element 130 and the bracket 110, and also guarantees good surface contact. Specifically, a first mounting hole 1128 can be provided on the surface 111 to be measured. A second mounting hole 1321 can be provided on the sheet-like portion 132. Fasteners 140 pass through the first mounting hole 1128 and the second mounting hole 1321 in sequence to fix the sheet-like portion 132 to the plate-like body 112. Fasteners 140 can be screws, bolts, etc. In embodiments not shown, the temperature sensing element 130 can also be connected to the bracket 110 by other means, such as welding, riveting, gluing, or snap-fit ​​connection.

[0075] See also Figure 2 , Figure 5 , Figure 6 , Figure 7 , Figure 8 , Figure 9 , Figure 11 , Figure 12 and Figure 13The lead portion 133 may include a probe body 1331 connected to the sheet portion 132. The probe body 1331 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 110 also rises rapidly, causing a sharp increase in the temperature change rate of the negative temperature coefficient thermistor.

[0076] 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.

[0077] In some embodiments, the probe body 1331 may contain a thermally conductive medium. This allows the temperature of the support 110 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 1331 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.

[0078] Further, see Figure 13 The lead portion 133 may further include a signal transmission line 1332 connected to the end of the probe body 1331 away from the sheet portion 132. This not only facilitates the transmission of the output signal converted from the temperature information collected by the temperature sensing element 130, but also prevents high temperatures from affecting the signal transmission line 1332, as the signal transmission line 1332 is relatively far from the sheet portion 132. Specifically, the signal transmission line 1332 may be covered with a protective sleeve. The protective sleeve further prevents high temperatures from affecting the signal transmission line 1332 and also avoids the problem of the signal transmission line 1332 being easily damaged when exposed.

[0079] Specifically, the ejector tube 120 may have an ejector body 121. The ejector body 121 may be connected to a gas pipe (not shown in the figure). Combustible gas can enter the ejector body 121 through the gas pipe, and then be ejected from the end of the ejector tube 120 away from the gas pipe, and finally ignited by an ignition needle to form a flame. The lead wire portion 133 may be connected to the end of the plate-shaped portion 132 away from the ejector body 121. In this way, the influence of the heat generated by combustion near the ejector tube 120 on the lead wire portion 133 is reduced, the lead wire portion 133 is protected, the service life of the temperature sensing element 130 is extended, and the accuracy of the temperature sensing element 130 is ensured.

[0080] In an embodiment not shown, the end of the signal transmission line 1332 furthest from the probe body 1331 can be connected to a controller. The temperature information collected by the plate-shaped portion 132 of the temperature sensing element 130 is converted into a signal by a conversion device and transmitted to the controller via the signal transmission line 1332. 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.

[0081] In the above embodiments, the temperature sensing element 130 is in close contact with the surface to be measured 111 via the sheet-like portion 132 to form surface contact. In embodiments not shown, the sheet-like portion 132 can be replaced with a wire. The wire can be disposed on the surface to be measured 111 and form line contact with the support 110. Specifically, see [reference needed]. Figure 8 In the case where the support 110 has a protrusion 1123, the linear body can form line contact with the first outer surface 1123a of the protrusion 1123, or it can form line contact with the inner wall surface of the accommodating cavity 1124. See also... Figure 11 When the support 110 has a recessed groove 1125, the linear body can form a line contact with the inner wall surface of the recessed groove 1125, or it can form a line contact with the bottom wall 1125c of the recessed groove 1125.

[0082] According to another aspect of this utility model, in conjunction with reference to... Figures 2 to 5 A burner 1 is provided, comprising a burner seat 20, a burner cap 30, and a burner head 10 as described above. The burner cap 30 and the burner seat 20 can be closed to form a mixing chamber 40. The mixing chamber 40 can be connected to an injector 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.

[0083] According to another aspect of this utility model, see also Figure 1A 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 a mounting opening. The panel 2 can cover the mounting 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.
