Technical Field
[0001] This utility model relates to the field of stove technology, and in particular to an anti-dry-burning probe, a burner assembly, and a stove. Background Technology
[0002] To prevent cookware from dry-burning during cooking, stovetops typically have anti-dry-burn probes at the burner to monitor the cookware temperature. These probes usually consist of a temperature sensor housed within a metal casing, with the sensor in thermal contact with a sensing end on the top of the casing. The sensor rests against the bottom of the cookware, allowing it to measure the temperature of the bottom through the sensing end of the casing. To protect the sensor from heat radiation from the flame, the casing is usually double-layered, creating an insulating space between the inner and outer layers.
[0003] To improve the temperature response of the anti-dry-burn probe when the pot temperature changes (e.g., adjusting the flame setting or adding food), one existing anti-dry-burn probe has an open bottom to reduce the metal volume of the outer shell and allow the insulation space to connect with the external environment. This reduces the heat capacity of the outer shell and utilizes the airflow at the burner for insulation. While this design improves the heating speed of the anti-dry-burn probe, allowing smart cooktops to execute corresponding cooking strategies based on temperature changes, it has poor resistance to temperature interference and is prone to triggering the anti-dry-burn function. For example, testing the anti-dry-burn function with a clay pot easily triggers it, leading to inaccurate test results. Utility Model Content
[0004] The purpose of this utility model is to provide an anti-dry-burning probe, a burner assembly, and a stove to alleviate the technical problem in the prior art where the bottom of the anti-dry-burning probe's outer shell is set to be open, resulting in a decrease in its resistance to temperature interference and easy triggering of the stove's anti-dry-burning function.
[0005] Firstly, this utility model provides an anti-dry-burning probe, including a temperature measuring element and a heat insulation layer;
[0006] The temperature measuring element includes a temperature measuring part and a non-temperature measuring part. The temperature measuring part is located at the top of the temperature measuring element and is used to contact the object to be measured.
[0007] The insulation layer is made of insulation material and covers the outside of the non-temperature measuring part.
[0008] In an optional embodiment, a housing assembly is further included, the top of which is provided with a heat transfer section, and the temperature measuring element is disposed inside the housing assembly. The temperature measuring section conducts heat to the object to be measured through the heat transfer section.
[0009] In an optional embodiment, the housing assembly includes an inner sleeve and an outer insulating layer made of insulating material, the outer insulating layer covering the circumferential sidewall of the inner sleeve.
[0010] In an optional embodiment, the inner sleeve is made of a thermally conductive material, the heat transfer part is the top end face of the inner sleeve, the temperature measuring element and the heat insulation layer are both disposed inside the inner sleeve, and the temperature measuring part abuts against the top of the inner sleeve.
[0011] In an optional embodiment, the top of the outer insulating layer is lower than the top of the inner sleeve to form a gap between them.
[0012] The housing assembly also includes an outer sleeve, the outer sleeve having a recessed portion on its circumferential sidewall near its top that is recessed toward the inside of the outer sleeve, the outer sleeve being fitted and fixed to the outside of the heat insulation outer layer, the recessed portion being located at the interval and abutting against the inner sleeve at the interval.
[0013] In an optional embodiment, the inner sleeve has an annular abutment extending circumferentially at its top edge, and the outer sleeve has an opening at its top, with the abutment abutting against the edge of the opening.
[0014] In an optional embodiment, the housing assembly further includes a heat-conducting element disposed at the top of the inner sleeve, the heat transfer portion being a through hole disposed inside the heat-conducting element, the temperature measuring element being disposed inside the through hole and exposed through the through hole; and the heat insulation layer covering the outside of the heat-conducting element.
[0015] In optional embodiments, it also includes a heat insulation pipe, a support cylinder, and a temperature data acquisition line;
[0016] The heat insulation pipe is made of heat insulation material, and the heat insulation layer is fixed to the top of the heat insulation pipe;
[0017] The support cylinder is slidably connected to the bottom of the heat insulation pipe, and the support cylinder is in communication with the heat insulation pipe;
[0018] The temperature data acquisition line is inserted through the support cylinder and the heat insulation pipe, with one end of the temperature data acquisition line near the heat insulation pipe connected to the temperature measuring element, and the other end extending out of the support cylinder.
[0019] Secondly, this utility model provides a burner assembly, including the anti-dry-burning probe described in any of the foregoing embodiments.
[0020] Thirdly, this utility model provides a stove, including the burner assembly described in the foregoing embodiments.
[0021] The anti-dry-burn probe provided by this utility model includes a temperature measuring element and a heat insulation layer. The temperature measuring element includes a temperature measuring part and a non-temperature measuring part, with the temperature measuring part located at the top of the temperature measuring element for contact with the object to be measured. The heat insulation layer is made of heat insulation material and covers the outside of the non-temperature measuring part. The anti-dry-burn probe provided by this utility model is used for measuring the temperature of a pot or pan while waiting to be measured. In use, the temperature measuring element of the anti-dry-burn probe can be placed below the pot or pan, with the temperature measuring part in contact with the bottom of the pot. During cooking, the temperature measuring part of the temperature measuring element can measure the temperature of the bottom of the pot in real time. Because the outside of the non-temperature measuring part of the temperature measuring element is covered with a heat insulation layer made of heat insulation material, only the temperature measuring part of the anti-dry-burn probe contacts the object to be measured, while the heat insulation layer can isolate the temperature and prevent the temperature around the pot from affecting the temperature measurement of the temperature measuring part. It should be noted that the insulation material of the insulation layer is a solid material such as insulation cotton, rather than the enclosed insulation space or circulating air used in existing technologies. Therefore, compared with the existing insulation method of enclosed insulation space, the anti-dry-burn probe provided by this utility model does not require a large metal shell for setting up an enclosed insulation space, thereby reducing the heat capacity of the shell and eliminating the need for an enclosed space for insulation. This effectively improves the temperature tracking performance of the temperature measuring element during the temperature measurement process, which is beneficial for the smart stove to sense the temperature of the pot and improves the cooking effect. Compared with the existing insulation method of circulating air, the anti-dry-burn probe provided by this utility model can effectively improve the temperature measuring element's resistance to interference from the surrounding ambient temperature by utilizing the insulation layer, thereby preventing the temperature measuring element from accidentally triggering the stove's anti-dry-burn function and further improving the cooking effect.
[0022] Compared with existing technologies, the anti-dry-burning probe provided by this utility model covers the non-temperature-measuring part of the temperature measuring element with a heat insulation layer. This not only reduces the interference of the ambient temperature around the object being measured on the temperature measuring element by using the heat insulation layer, thus improving the temperature measuring element's anti-interference ability, making it less likely for the temperature measuring element to trigger the stove's anti-dry-burning function, but also allows only the temperature measuring part of the temperature measuring element to contact the bottom of the pot or the object being measured. At the same time, it eliminates the need for a closed heat insulation space, effectively increasing the temperature tracking accuracy between the temperature measuring element and the object being measured. This facilitates the smart stove's perception of the pot's temperature and improves the cooking effect.
[0023] The burner assembly provided by this utility model includes the aforementioned anti-dry-burning probe, and therefore the burner assembly has the same beneficial effects as the aforementioned anti-dry-burning probe.
[0024] The stove provided by this utility model includes the above-mentioned burner assembly, and therefore the stove has the same beneficial effects as the above-mentioned burner assembly. Attached Figure Description

Detailed Implementation
[0031] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this utility model, and not all embodiments. The components of the embodiments of this utility model described and shown in the accompanying drawings can generally be arranged and designed in various different configurations.
[0032] Therefore, the following detailed description of the embodiments of the present invention provided in the accompanying drawings is not intended to limit the scope of the claimed invention, but merely to illustrate selected embodiments of the invention. All other embodiments obtained by those skilled in the art based on the embodiments of the present invention without inventive effort are within the scope of protection of the present invention.
[0033] The following detailed description, in conjunction with the accompanying drawings, outlines some embodiments of the present invention. Unless otherwise specified, the following embodiments and features can be combined with each other.
[0034] Example:
[0035] The anti-dry-burning probe provided in this embodiment includes a temperature measuring element 1 and a heat insulation layer 2; the temperature measuring element 1 includes a temperature measuring part 10 and a non-temperature measuring part 11, the temperature measuring part 10 is located on the top of the temperature measuring element 1 and is used to contact the object to be measured; the heat insulation layer 2 is made of heat insulation material and covers the outside of the non-temperature measuring part 11.
[0036] The anti-dry-burn probe provided in this embodiment is used for measuring the temperature of a pot or other object waiting to be measured. In use, the temperature measuring element 1 of the anti-dry-burn probe can be placed below the pot or other object waiting to be measured, and the temperature measuring part 10 can be in contact with the bottom of the pot. During cooking, the temperature measuring part 10 of the temperature measuring element 1 can measure the temperature of the bottom of the pot in real time. Since the outside of the non-temperature measuring part 11 of the temperature measuring element 1 is covered with a heat insulation layer 2 made of heat insulation material, only the temperature measuring part 10 of the anti-dry-burn probe is in contact with the object to be measured, and the heat insulation layer 2 can isolate the temperature and prevent the temperature around the pot from affecting the temperature measuring part 10.
[0037] The heat insulation layer 2 is used to reduce the heat radiation of the flame. It can be made of high-temperature resistant heat insulation materials such as foam, heat insulation cotton, or electric ceramic stove heat insulation materials. In this embodiment, the heat insulation layer 2 is preferably able to withstand temperatures of 500 degrees Celsius or higher. It should be noted that the heat insulation material of the heat insulation layer 2 is a solid material such as heat insulation cotton, rather than the closed heat insulation space or circulating air used in the prior art. Therefore, compared with the existing heat insulation method of closed heat insulation space, the anti-dry burning probe provided in this embodiment does not need to use a large amount of metal shell for setting up a closed heat insulation space, thereby reducing the heat capacity of the shell and eliminating the need for closed space for heat insulation. This effectively improves the temperature tracking performance of the temperature measuring element 1 during the temperature measurement process. When the temperature of the bottom of the pot changes due to adjusting the flame level or adding food to the pot, the temperature measuring element 1 can more easily detect the temperature change of the bottom of the pot (the existing closed space heat insulation method will cause the temperature measurement result of the probe to remain basically unchanged when food is added to the pot). Therefore, the temperature tracking performance of the anti-dry burning probe provided in this embodiment can be improved, which is beneficial for the smart stove to sense the temperature of the pot and improve the cooking effect.
[0038] Compared to existing air-circulating insulation methods, the anti-dry-burn probe provided in this embodiment can effectively enhance the temperature sensing element 1's resistance to interference from the surrounding ambient temperature by utilizing the insulation layer 2, thereby preventing the temperature sensing element 1 from accidentally triggering the stove's anti-dry-burn function and further improving the cooking effect.
[0039] Compared with the prior art, the anti-dry-burning probe provided in this embodiment covers the non-temperature measuring part 11 of the temperature measuring element 1 with a heat insulation layer 2. This not only reduces the interference of the ambient temperature around the object being measured on the temperature measuring element 1 by using the heat insulation layer 2 for heat insulation, but also improves the anti-interference ability of the temperature measuring element 1, making it less likely for the temperature measuring element 1 to trigger the anti-dry-burning function of the stove. Furthermore, it allows only the temperature measuring part 10 of the temperature measuring element 1 to contact the bottom of the pot or the object being measured, without the need for a closed heat insulation space. This effectively increases the temperature tracking between the temperature measuring element 1 and the object being measured, which is beneficial for the smart stove to sense the temperature of the pot and improves the cooking effect.
[0040] like Figure 1 , Figure 2 and Figure 3 As shown, the anti-dry-burning probe provided in this embodiment also includes a housing assembly 3. The top of the housing assembly 3 is provided with a heat transfer part 30. The temperature measuring element 1 is disposed inside the housing assembly 3. The temperature measuring part 10 conducts heat to the object to be measured through the heat transfer part 30.
[0041] The housing assembly 3 is used to protect the temperature measuring element 1 and can support the temperature measuring element 1 so that the temperature measuring element 1 can be stably attached to the bottom of the object to be measured.
[0042] It should be noted that since the temperature measuring element 1 provided in this embodiment uses the heat insulation layer 2 for heat insulation, its heat capacity is lower than that of the closed heat insulation space. Moreover, the heat insulation layer 2 does not need to adopt a double-layer shell structure, which can reduce the metal volume of the shell and further reduce the heat capacity of the shell. Therefore, even though the anti-dry burning probe provided in this embodiment also includes the shell assembly 3, it can still improve the temperature tracking performance compared to the existing anti-dry burning probe that uses a closed heat insulation space for heat insulation.
[0043] The structure of the heat transfer part 30 is not limited, as long as it can transfer heat from the object to be measured to the temperature measuring part 10. For example, the heat transfer part 30 can be the top of the housing assembly 3. In this case, the top of the housing assembly 3 needs to be made of a thermally conductive material so that the heat from the object to be measured can be transferred to the temperature measuring part 10. Alternatively, the heat transfer part 30 can be a perforation provided on the top of the housing, allowing the heat from the object to be measured to enter the interior of the housing assembly 3. The inner edge of the perforation can abut against the outer edge of the temperature measuring part 10.
[0044] like Figure 1 , Figure 2 and Figure 3 As shown, the housing assembly 3 may include an inner sleeve 31 and a heat-insulating outer layer 32. The heat-insulating outer layer 32 is made of heat-insulating material and covers the circumferential sidewall of the inner sleeve 31.
[0045] The inner sleeve 31 can be made of materials with high hardness such as metal or alloy. The inner sleeve 31 is used to provide support and ensure the structural strength of the anti-dry burning probe.
[0046] The outer heat insulation layer 32 serves to insulate against heat and reduce the heat conduction from the flame to the inner sleeve 31, thereby further preventing the ambient temperature from affecting the temperature measurement process of the temperature measuring element 1.
[0047] The material of the outer heat insulation layer 32 can be the same as that of the heat insulation layer 2, or the materials of the outer heat insulation layer 32 and the heat insulation layer 2 can be different heat insulation materials. As mentioned above, there are many choices for heat insulation materials. In this embodiment, the preferred heat insulation material is heat insulation cotton, foam material, ceramic fiber, or electric ceramic stove heat insulation material, etc., which are high temperature resistant and have good plasticity.
[0048] Furthermore, such as Figure 1 and Figure 2 As shown, the inner sleeve 31 is made of thermally conductive material, the heat transfer part 30 is the top end face of the inner sleeve 31, the temperature measuring element 1 and the heat insulation layer 2 are both disposed inside the inner sleeve 31, and the temperature measuring part 10 abuts against the top of the inner sleeve 31.
[0049] When the inner sleeve 31 is made of a heat-conducting material, the heat transfer part 30 can be directly formed on the top end face of the inner sleeve 31, thereby simplifying the manufacturing process of the housing assembly 3.
[0050] At this time, the inner sleeve 31 can be made of thermally conductive metals such as copper. Furthermore, the outer side of the inner sleeve 31 can also be plated with a metal that prevents discoloration, such as titanium.
[0051] Furthermore, such as Figure 1 As shown, the top of the heat-insulating outer layer 32 is lower than the top of the inner sleeve 31 to form a gap between them; the housing assembly 3 also includes an outer sleeve 33, and the circumferential sidewall of the outer sleeve 33 is provided with a recessed portion 330 near its top, which is recessed toward the inside of the outer sleeve 33. The outer sleeve 33 is fitted and fixed to the outside of the heat-insulating outer layer 32, and the recessed portion 330 is located at the gap and abuts against the inner sleeve 31 at the gap.
[0052] The outer sleeve 33 can be made of metal or alloy materials, such as stainless steel.
[0053] The outer sleeve 33 is used to support and protect the heat insulation outer layer 32 and the inner sleeve 31, thereby further improving the structural stability and operational stability of the anti-dry burning probe.
[0054] The gap between the top of the heat-insulating outer layer 32 and the top of the inner sleeve 31 is used to accommodate the recess 330 of the outer sleeve 33, which is used to fix the inner sleeve 31, thereby effectively ensuring the connection stability between the outer sleeve 33 and the inner sleeve 31.
[0055] In addition, the recessed portion 330 can also guide the installation process of the inner sleeve 31 when it is installed inside the outer sleeve 33, thereby improving the ease of installation of the inner sleeve 31.
[0056] It should also be noted that existing anti-dry-burning probes, to ensure the stability of the temperature sensor within its housing, typically have a downward-facing slot on the top of the inner shell of a double-layered housing, into which the temperature sensor is then secured. However, in this embodiment, as... Figure 1 and Figure 2 As shown, when the heat insulation layer 2 is installed inside the inner sleeve 31, the heat insulation layer 2 can not only play a role in heat insulation, but also play a role in fixing the temperature measuring element 1, thereby improving the installation stability of the temperature measuring element 1. No additional slot is required, which effectively simplifies the structure of the inner sleeve 31 and makes the inner sleeve 31 easier to process.
[0057] Furthermore, such as Figure 1 As shown, the inner sleeve 31 has an annular abutment portion 310 extending circumferentially at its top edge, and the outer sleeve 33 has an opening at its top, with the abutment portion 310 abutting against the edge of the opening.
[0058] The abutting part 310 is used to cooperate with the top opening of the outer sleeve 33, and plays a supporting and limiting role in the installation process of the inner sleeve 31 inside the outer sleeve 33. This not only further improves the ease of installation of the inner sleeve 31, but also further improves the installation stability of the inner sleeve 31.
[0059] When the housing assembly 3 does not include the outer sleeve 33, such as Figure 2 As shown, the outer heat insulation layer 32 can be directly covered on the outside of the inner sleeve 31, with the top of the outer heat insulation layer 32 flush with the top of the inner sleeve 31 and the bottom of the outer heat insulation layer 32 flush with the bottom of the inner sleeve 31. In this case, the heat transfer part 30 remains the top end face of the inner sleeve 31. Compared to this embodiment... Figure 1 The anti-dry-burning probe shown is... Figure 2 The anti-dry-burning probe shown can not only prevent flame radiation from being transmitted to the heat insulation outer layer 32 through the outer sleeve 33, thereby preventing the inner sleeve 31 from being more susceptible to the influence of ambient temperature, but also effectively simplify the structure of the housing assembly 3, which is conducive to assembly and production.
[0060] When the housing assembly 3 does not include the outer sleeve 33, such as Figure 3 As shown, a heat-conducting element 34 can also be provided on the top of the inner sleeve 31. In this case, the heat transfer part 30 is a through hole provided inside the heat-conducting element 34, the temperature measuring element 1 is provided in the through hole and the temperature measuring part 10 is exposed through the through hole; the heat insulation layer 2 covers the outside of the heat-conducting element 34.
[0061] The heat-conducting element 34 is used to protect the temperature measuring element 1 and can transfer heat from the object to be measured to the temperature measuring part 10 on the top of the temperature measuring element 1 through the through hole. At this time, the periphery of the non-temperature measuring part 11 of the temperature measuring element 1 corresponds to the periphery of the heat-conducting element 34. The heat insulation layer 2 covers the periphery of the heat-conducting element 34, which can still isolate the periphery of the non-temperature measuring part 11 from the heat in the external environment, thereby providing heat insulation for the non-temperature measuring part 11.
[0062] At this time, both the heat-conducting element 34 and the inner sleeve 31 can be made of heat-conducting metals or alloys. Preferably, both the heat-conducting element 34 and the inner sleeve 31 can be made of inexpensive metals.
[0063] Compared to this embodiment Figure 2 The anti-dry-burning probe shown is... Figure 3 The anti-dry-burn probe shown can reduce the heat conduction surface of the heat conduction part, thereby reducing the influence of heat radiation at the top of the inner sleeve 31 on the temperature measuring part 10.
[0064] Furthermore, such as Figure 3 As shown, in order to facilitate processing and further improve the heat insulation effect, the heat insulation layer 2 can be fixed to the top of the inner sleeve 31, and the heat insulation layer 2 is connected to the heat insulation outer layer 32.
[0065] like Figure 1 , Figure 2 and Figure 3 As shown, the anti-dry-burning probe provided in this embodiment also includes a push rod 4 and a temperature data acquisition line 5; the push rod 4 is hollow, and the push rod 4 is slidably connected to the lower part of the inner sleeve 31 and the hollow part of the push rod 4 is connected to the inside of the inner sleeve 31; the temperature data acquisition line 5 passes through the inner sleeve 31 and the push rod 4, and one end of the temperature data acquisition line 5 near the inner sleeve 31 is connected to the temperature measuring element 1, and the other end extends out of the push rod 4.
[0066] The temperature data acquisition line 5 is used to transmit the temperature information detected by the temperature measuring element 1 to the control device such as the circuit board of the stove. Based on this, one end of the temperature data acquisition line 5 near the inner sleeve 31 needs to be connected to the temperature measuring element 1, and the other end needs to extend out of the push rod 4 and be connected to the circuit board through the terminal or other connector.
[0067] It should be noted that, due to Figure 3 The inner sleeve 31 of the anti-dry burning probe shown has a heat-conducting element 34 fixed at the top, and the temperature measuring element 1 is installed in the heat-conducting element 34. Therefore, in order to facilitate the connection between the temperature data acquisition line 5 and the circuit board, the top of the inner sleeve 31 can be provided with a through hole for the temperature data acquisition line 5 to pass through.
[0068] The sliding connection between the push rod 4 and the inner sleeve 31 is used to allow the length of the anti-dry-burn probe to be varied. When the distance between the bottom of the pot and the surface of the stove is different, the anti-dry-burn probe can be extended or shortened so that the temperature measuring part 10 or the heat transfer part 30 is always in contact with the bottom of the pot, thereby allowing the anti-dry-burn probe to be adapted to different sizes of pots.
[0069] In this embodiment, the push rod 4 can be fixed to the stove, and the inner sleeve 31 is slidably connected to the push rod 4. When the pot is placed at the burner of the stove, the pot is moved away from the burner, or different sizes of pots are placed at the burner, the inner sleeve 31 can slide relative to the push rod 4 as the position of the pot changes.
[0070] Furthermore, such as Figures 1-3 As shown, the outer wall of the push rod 4 may be provided with a limiting protrusion 6, and the push rod 4 is fixed to the stove through the limiting protrusion 6.
[0071] like Figures 1-3 As shown, the anti-dry burning probe provided in this embodiment may also include a reset member 7, which is connected between the inner sleeve 31 and the push rod 4, and is used to store energy when the inner sleeve 31 and the push rod 4 slide close to each other.
[0072] When the bottom of the cookware presses down on the temperature measuring part 10 or the heat transfer part 30, the inner sleeve 31 and the push rod 4 will slide closer to each other, and the reset member 7 will store energy at this time; when the bottom of the cookware moves upward away from the temperature measuring part 10 or the heat transfer part 30, the reset member 7 will release energy, thereby driving the inner sleeve 31 to move upward, so that the temperature measuring part 10 or the heat transfer part 30 is reset.
[0073] To facilitate limiting the sliding process between the inner sleeve 31 and the push rod 4, such as Figures 1-3 As shown, in this embodiment, the bottom of the inner sleeve 31 is preferably provided with a bottom shell 311, and the bottom shell 311 is provided with a through hole for the push rod 4 and the temperature data acquisition line 5 to pass through; the end of the push rod 4 near the inner sleeve 31 is located in the inner sleeve 31, and a limiting ring 40 is fixed on the periphery of the end of the push rod 4. The limiting ring 40 abuts against the inner side of the bottom shell 311 to prevent the push rod 4 from coming out of the inner sleeve 31.
[0074] When installing the inner sleeve 31, push rod 4 and bottom shell 311, the end of the push rod 4 with the limiting ring 40 can be inserted into the inner sleeve 31 first, and then the bottom shell 311 can be fixed to the bottom of the inner sleeve 31 by glue or welding.
[0075] In this embodiment, the anti-dry-burning probe may not require the aforementioned housing assembly 3, such as... Figure 4As shown, the anti-dry-burning probe also includes a heat insulation tube 8, a support cylinder 9, and a temperature data acquisition line 5. The heat insulation tube 8 is made of heat insulation material, and the heat insulation layer 2 is fixed to the top of the heat insulation tube 8. The support cylinder 9 is slidably connected to the bottom of the heat insulation tube 8, and the support cylinder 9 is connected to the heat insulation tube 8. The temperature data acquisition line 5 passes through the support cylinder 9 and the heat insulation tube 8, and one end of the temperature data acquisition line 5 near the heat insulation tube 8 is connected to the temperature measuring element 1, and the other end extends out of the support cylinder 9.
[0076] At this time, the heat insulation pipe 8 can be used to protect and support the temperature measuring element 1, and the heat insulation pipe 8 can be used to further insulate the non-temperature measuring part 11 of the temperature measuring element 1, thereby reducing the influence of the external ambient temperature on the temperature measuring element 1.
[0077] Compared to this embodiment Figure 3 The anti-dry-burning probe shown is... Figure 4 The anti-dry-burn probe shown can further improve the heat insulation effect of the temperature measuring element 1, and effectively simplify the overall structure of the anti-dry-burn probe, reducing the manufacturing cost of the anti-dry-burn probe.
[0078] The temperature data acquisition line 5 is also used to transmit the temperature information detected by the temperature measuring element 1 to the control devices such as the circuit board of the stove 90. The support cylinder 9 can be fixed to the stove 90 by the limiting protrusion 6 set at its bottom. The support cylinder 9 is slidably connected to the heat insulation tube 8, which also allows the length of the anti-dry-burning probe to be variable, so that the anti-dry-burning probe can be adapted to cookware of different sizes.
[0079] To facilitate limiting the sliding process between the support cylinder 9 and the insulation tube 8, such as Figure 4 As shown, the top of the support cylinder 9 may be provided with a sliding hole, and the bottom of the heat insulation pipe 8 extends into the support cylinder 9 after passing through the sliding hole. A heat insulation ring 80 may be fixed on the periphery of the bottom of the heat insulation pipe 8, and the heat insulation ring 80 abuts against the top end face of the support cylinder 9 on the periphery of the sliding hole.
[0080] Furthermore, such as Figure 4 As shown, the anti-dry-burning probe may also include a reset element 7, which is connected between the support cylinder 9 and the heat insulation tube 8. This reset element 7 stores energy when the support cylinder 9 and the heat insulation tube 8 slide close to each other. Similar to the aforementioned reset element 7, it can also release energy when the heat insulation tube 8 slides away from the support cylinder 9, thereby driving the heat insulation tube 8 to reset.
[0081] This embodiment also provides a burner assembly, which includes the aforementioned anti-dry-burning probe. Therefore, the burner assembly and the aforementioned anti-dry-burning probe can solve the same technical problem and achieve the same technical effect, which will not be described in detail here.
[0082] This embodiment also provides a stove 90, which includes the above-mentioned burner assembly. Therefore, the stove 90 and the burner assembly can solve the same technical problems and achieve the same technical effects, which will not be described in detail here.
[0083] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this utility model, and are not intended to limit it. Although the utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some or all of the technical features therein.
