Probe assembly and burner including it

Abstract

This invention discloses a probe assembly and a burner including the same. The probe assembly includes a temperature probe for measuring the temperature of the bottom of a cookware. The probe assembly includes an upper movable part and a lower movable part. The temperature probe is disposed at the top of the upper movable part, and the bottom of the upper movable part is supported by the lower movable part. The upper movable part is horizontally movable and / or swings relative to the lower movable part. By enabling the upper movable part to move horizontally and / or swing relative to the lower movable part, when the cookware moves horizontally—for example, when the user actively shakes the cookware by swishing it to heat oil, stirring, tossing, or transferring food—or when the cookware passively shakes due to sliding on a pot rack or being placed off-center, the temperature probe can still be in contact with the bottom of the cookware to measure the temperature. This reduces the risk of the temperature probe not making contact with the bottom of the cookware, reduces the risk of the burner accidentally shutting off, and improves the user experience.

Description

Technical Field

[0001] The present invention relates to a probe assembly and a burner including the same. Background Technology

[0002] The burner uses a probe to measure the temperature of the bottom of the pot. When the bottom of the pot gets too hot, the probe assembly can provide timely feedback and prevent dry burning, thus avoiding dangerous situations. The temperature probe is usually located at the top of the probe assembly. During use, to ensure that the temperature probe always contacts the bottom of the pot for temperature measurement, the probe assembly uses a flexible element to allow the temperature probe to move up and down.

[0003] In actual use, cookware is not placed statically on the burner; it moves in different horizontal directions. For example, users may actively shake the cookware when performing actions such as swishing the pan to heat oil, stirring, tossing, or moving the pan to pour food. Alternatively, the cookware may passively shake due to sliding on the pan rack or being placed off-center. Some users place the cookware horizontally or at an angle during cooking, rather than vertically, causing it to frequently collide with the probe, resulting in probe misalignment. Since the existing probe assembly can only move vertically, the collision with the cookware often causes the probe assembly to become misaligned, preventing the temperature probe from contacting the bottom of the cookware. This can lead to the burner accidentally shutting off, affecting the user's cooking process. Summary of the Invention

[0004] The technical problem to be solved by the present invention is to overcome the defect in the prior art where the probe is tilted after the pot collides with the probe and cannot make contact with the bottom of the pot, thereby causing the burner to shut off accidentally. The present invention provides a probe assembly and a burner including the probe assembly.

[0005] The present invention solves the above-mentioned technical problems through the following technical solution:

[0006] A probe assembly includes a temperature probe for measuring the temperature of the bottom of a cookware.

[0007] The probe assembly includes an upper movable part and a lower movable part. The temperature probe is disposed at the top of the upper movable part, and the bottom of the upper movable part is mounted on the lower movable part. The upper movable part is capable of horizontal movement and / or swinging relative to the lower movable part.

[0008] In this design, during cooking, the cookware is mounted on the burner, and a temperature probe is placed against the bottom of the cookware to measure its temperature. If the cookware is dry-burning or the bottom temperature is too high, the burner can be shut off promptly, reducing the risk of dry-burning. The upper movable part can move horizontally and / or swing relative to the lower movable part. By incorporating the upper movable part, when the cookware moves horizontally—for example, when the user actively shakes the cookware by swishing it to heat oil, stirring, tossing, or transferring food—or passively shakes the cookware by sliding it on the cookware rack or placing it off-center, the temperature probe can still maintain contact with the bottom of the cookware to measure the temperature. This reduces the risk of the probe not making contact with the bottom of the cookware, lowers the risk of the burner accidentally shutting off, and improves the user experience.

[0009] Preferably, the upper movable component includes a heat collection plate and an upper housing, the heat collection plate having a receiving cavity, and the temperature measuring probe being disposed within the receiving cavity;

[0010] The top end of the upper shell is connected to the heat collection plate, and the bottom end of the upper shell is located on the lower movable member and can move horizontally and / or swing on the lower movable member.

[0011] In this solution, with the above-mentioned configuration, the heat collection plate is used to abut against the bottom of the pot and conduct heat. The heat collection plate is provided with a receiving cavity, which facilitates the setting of the temperature probe and is conducive to the accurate temperature measurement of the temperature probe. The bottom end of the upper shell is located on the lower movable part, and during the horizontal movement and / or swinging of the upper shell, there is always a fulcrum between the upper shell and the lower movable part to support the upper shell, which is conducive to the reliability of the connection between the upper shell and the lower movable part.

[0012] Preferably, the upper movable member further includes an upper elastic member disposed inside the upper housing, the bottom end of the upper elastic member acting on the lower movable member, and the upper elastic member being used to reset the horizontal movement and / or swing of the upper movable member.

[0013] In this design, an upper elastic element is incorporated, with its bottom end acting on a lower movable element. When the probe assembly is subjected to a horizontal external force, the upper movable element moves horizontally and / or swings, causing the upper housing to move horizontally and / or swing accordingly, resulting in deformation of the upper elastic element in the horizontal direction. When the cookware is removed or the horizontal external force disappears, the restoring force of the upper elastic element allows the upper movable element to automatically return to its initial state, eliminating the need for the user to readjust the upper movable element and facilitating the use of the probe assembly.

[0014] Preferably, the top end of the upper housing has an inward / outward bend, and the upper housing is connected to the heat collection plate through the bend.

[0015] In this solution, the above-mentioned settings increase the connection area between the upper shell and the heat collection plate, thereby improving the reliability of the connection between the upper shell and the heat collection plate.

[0016] Preferably, the bottom end of the upper housing has a first support portion extending inward / outward, and the upper housing is mounted on the lower movable member via the first support portion.

[0017] In this solution, the contact area between the upper housing and the lower movable part is increased by the above-mentioned arrangement. In particular, when the upper movable part moves horizontally and / or swings, the upper housing can still be supported by the lower movable part through the first support part, and ensure that there is a fulcrum between the upper housing and the lower movable part to support the upper housing, which is beneficial to the normal use of the probe assembly.

[0018] Preferably, the probe assembly includes an upper protective shell connected to the upper housing and spaced circumferentially from the outer side wall of the upper housing, the upper protective shell extending axially over at least a portion of the upper movable member of the upper housing.

[0019] In this design, the burner generates high-temperature flue gas during operation, which can cause thermal interference to the temperature probe. The above-mentioned design can prevent the high-temperature flue gas from approaching the upper moving part, which is beneficial to the accurate temperature measurement of the temperature probe, reduces the risk of false temperature measurement leading to accidental burner shutdown, and improves the user experience of the probe assembly. At the same time, the above-mentioned design can reduce the working environment of the upper elastic component and increase its service life.

[0020] Preferably, the lower movable member includes a lower housing, a lower elastic member and a support rod, the bottom end of the lower elastic member acts on the support rod, the top end of the lower elastic member acts on the lower housing, the upper movable member is mounted on the lower housing, and the lower housing is movable in the vertical direction.

[0021] In this design, when the cookware is placed on the burner, it exerts downward pressure on the probe assembly. This pressure is transmitted to the top of the lower housing through the upper movable component. The support rod is fixed relative to the burner, and the lower elastic component is compressed, allowing the height of the probe assembly to be adjusted. This makes the probe assembly suitable for cookware of different shapes, improving the user experience. When the cookware is removed, the restoring force of the lower elastic component returns the lower movable component to its initial state, eliminating the need for the user to readjust the lower movable component and facilitating the use of the probe assembly.

[0022] Preferably, the bottom of the lower housing has an inwardly bent limiting portion, which is used to abut against the support rod to prevent the support rod from detaching from the lower housing.

[0023] In this solution, the above-mentioned settings improve the reliability of the connection between the lower housing and the support rod, facilitating the installation and use of the probe assembly.

[0024] Preferably, the top of the lower housing has a second support extending inward / outward, and the bottom of the upper movable member is mounted on the second support.

[0025] In this solution, the contact area between the lower housing and the upper movable part is increased by the above-mentioned arrangement. In particular, when the upper movable part moves horizontally and / or swings, the upper movable part can still be mounted on the lower housing through the second support part, and it is ensured that there is a fulcrum between the upper movable part and the lower housing for supporting the upper movable part, which is beneficial to the normal use of the probe assembly.

[0026] Preferably, the second support portion is L-shaped, the probe assembly includes a wire that passes through the second support portion, and the top end of the lower elastic member is sleeved on the second support portion.

[0027] In this design, the second support portion has a horizontal portion and a vertical portion. The horizontal portion extends inward along the top of the lower housing, and the vertical portion is located inside the horizontal portion and extends downward. The wire passes through the second support portion, reducing the risk of the wire getting tangled inside the upper or lower housing, and providing space for the horizontal movement and / or swinging of the upper movable part. The top of the lower elastic member is sleeved on the outside of the vertical portion. The vertical portion limits the top of the lower elastic member, and the lower elastic member acts on the horizontal portion, reducing the risk of the lower elastic member shifting and enabling the lower elastic member to deform in the vertical direction, which is beneficial for the assembly and use of the probe assembly.

[0028] Preferably, the lower housing has at least one guide portion, and the support rod has at least one matching portion. The matching portion corresponds one-to-one with the guide portion, and the matching portion slides on the guide portion to realize the movement of the lower housing in the vertical direction.

[0029] In this solution, the lower housing moves vertically and is restricted from moving or rotating horizontally. This ensures that the lower elastic element is only subjected to vertical force and deforms only in the vertical direction, reducing the risk of deformation and reduced adaptability of the probe assembly due to horizontal force. This is beneficial for the use of the probe assembly.

[0030] Preferably, the lower movable member further includes a connector, which is disposed between the upper movable member and the lower housing. The probe assembly includes a wire, the inner diameter of the connector is smaller than the inner diameter of the lower housing, and the wire passes through the lower movable member, the connector, and the upper movable member in sequence and is connected to the temperature probe.

[0031] In this solution, by restricting the movement of the wire between the first or second movable part, the risk of the wire getting tangled inside the upper or lower housing is reduced, and space is provided for the horizontal movement and / or swinging of the upper movable part, which is beneficial to the use of the probe assembly.

[0032] Preferably, the top of the connector has an outwardly extending third support portion, and the upper movable member is mounted on the third support portion.

[0033] In this solution, the contact area between the lower housing and the upper movable part is increased by the above-mentioned arrangement. In particular, when the upper movable part moves horizontally and / or swings, the upper movable part can still be mounted on the lower housing through the third support part, and it is ensured that there is a fulcrum between the upper movable part and the lower housing for supporting the upper movable part, which is beneficial to the normal use of the probe assembly.

[0034] Preferably, the probe assembly includes a lower protective housing connected to the lower housing and spaced circumferentially from the outer side wall of the lower housing, the lower protective housing extending axially over at least a portion of the lower movable member.

[0035] In this design, the burner generates high-temperature flue gas during operation, which can cause thermal interference to the temperature probe. The above-mentioned design can prevent the high-temperature flue gas from approaching the lower moving part, reduce the working environment of the lower elastic part, and increase the service life of the lower elastic part.

[0036] Preferably, the probe assembly includes at least one additional movable member disposed between the upper movable member and the lower movable member, the additional movable member being movable relative to the lower movable member and the upper movable member.

[0037] In this solution, by setting an additional movable part that can move relative to the lower and upper movable parts, the range of motion of the temperature probe in both the vertical and horizontal directions is increased. This improves the adaptability of the probe assembly to cookware of different shapes. At the same time, when the cookware moves horizontally, the temperature probe can also fit against the bottom of the cookware to measure the temperature, reducing the risk of the temperature probe not being able to contact the bottom of the cookware and improving the user experience.

[0038] A burner comprising the probe assembly described above.

[0039] The positive and progressive effects of this invention are as follows: the upper movable part can move horizontally and / or swing relative to the lower movable part. By setting the upper movable part, when the cookware moves horizontally, such as when the user actively shakes the cookware by sliding the pan to heat oil, stirring the pan, tossing the pan to stir, or moving the pan to pour food; or when the cookware shakes passively due to sliding on the pan rack or being placed off-center, the temperature probe can also be in contact with the bottom of the cookware to measure the temperature. This reduces the risk that the temperature probe cannot make contact with the bottom of the cookware, reduces the risk of the burner being accidentally turned off, and improves the user experience.

[0068] The present invention will be further illustrated by way of embodiments below, but the present invention is not limited to the scope of the embodiments described herein.

[0069] Example 1

[0070] This embodiment provides a probe assembly, such as Figure 1 and Figure 2 As shown, the probe assembly includes a temperature probe 1, which is used to measure the temperature of the bottom of the cookware. The probe assembly includes an upper movable part 2 and a lower movable part 3. The temperature probe 1 is disposed at the top of the upper movable part 2, and the bottom of the upper movable part 2 is mounted on the lower movable part 3. The upper movable part 2 can move horizontally and / or swing relative to the lower movable part 3.

[0071] During cooking, the cookware is placed on the burner, and the temperature probe 1 is in contact with the bottom of the cookware to measure its temperature. If the cookware is dry-burning or the bottom temperature is too high, the burner can be shut off promptly, reducing the risk of dry-burning. The upper movable part 2 can move horizontally and / or swing relative to the lower movable part 3. By setting the upper movable part 2, when the cookware moves horizontally—for example, when the user actively shakes the cookware by swishing it to heat oil, stirring, tossing, or transferring food—or when the cookware slides on the cookware rack or is placed off-center, the temperature probe 1 can still contact the bottom of the cookware to measure the temperature. This reduces the risk of the temperature probe 1 not making contact with the bottom of the cookware, reduces the risk of the burner accidentally shutting off, and improves the user experience.

[0072] In this embodiment, the temperature probe 1 is a thermistor, electrically connected to the burner's control unit via wire 4. During cooking, the pot is placed on the burner, and the temperature probe 1 rests against the bottom of the pot to measure its temperature. When the pot is dry-burning or the bottom temperature is too high, the control unit can promptly shut off the burner, reducing the risk of dry-burning. Wire 4 passes through the upper movable part 2 and the lower movable part 3. In other alternative embodiments, the temperature probe 1 can also transmit temperature signals wirelessly, and the burner's control unit controls the burner upon receiving the temperature signal.

[0073] As a preferred implementation method, such as Figures 1-3 As shown, the upper movable component 2 includes a heat-collecting plate 21 and an upper shell 22. The heat-collecting plate 21 has a receiving cavity 211, in which the temperature probe 1 is disposed. The top end of the upper shell 22 is connected to the heat-collecting plate 21, and the bottom end of the upper shell 22 is disposed on the lower movable component 3 and can move horizontally and / or swing on the lower movable component 3. The heat-collecting plate 21 is used to abut against the bottom of the pot and conduct heat. The receiving cavity 211 on the heat-collecting plate 21 facilitates the placement of the temperature probe 1 and is beneficial to the accurate temperature measurement of the temperature probe 1. The bottom end of the upper shell 22 is disposed on the lower movable component 3, and during the horizontal movement and / or swinging of the upper shell 22, there is always a fulcrum between the upper shell 22 and the lower movable component 3 to support the upper shell 22, which is beneficial to the reliability of the connection between the upper shell 22 and the lower movable component 3.

[0074] In this embodiment, the receiving cavity 211 is disposed on the lower surface of the heat collection plate 21, the sidewall of the receiving cavity 211 is integrally formed with the heat collection plate 21, and the bottom of the receiving cavity 211 is provided with an opening, and the temperature measuring probe 1 is disposed inside the receiving cavity 211 by snap-fit. In other alternative embodiments, the sidewall of the receiving cavity 211 can also be fixed to the heat collection plate 21 by welding, riveting, threading or other connection methods.

[0075] As a preferred implementation method, such as Figures 1-3 As shown, the upper movable member 2 also includes an upper elastic member 23, which is disposed inside the upper housing 22. The bottom end of the upper elastic member 23 acts on the lower movable member 3, and the upper elastic member 23 is used to reset the horizontal movement and / or swing of the upper movable member 2. By setting the upper elastic member 23, the bottom end of the upper elastic member 23 acts on the lower movable member 3. When the probe assembly is subjected to a horizontal external force, the upper movable member 2 moves horizontally and / or swings, and the upper housing 22 moves horizontally and / or swings accordingly, causing the upper elastic member 23 to deform in the horizontal direction. When the cookware is removed or the horizontal external force disappears, the restoring force of the upper elastic member 23 allows the upper movable member 2 to automatically return to its initial state, saving the user the step of readjusting the upper movable member 2 and facilitating the use of the probe assembly.

[0076] In this embodiment, the upper elastic element 23 is a spring. The top end of the upper elastic element 23 acts on the heat collection plate 21, and the upper elastic element 23 is sleeved on the outer wall of the receiving cavity 211, reducing the risk of the top end of the upper elastic element 23 shifting relative to the heat collection plate 21; the upper elastic element 23 is mounted on the top end of the lower movable element 3. In other alternative embodiments, the bottom end of the upper elastic element 23 can also be fixed to the lower movable element 3 by welding or bonding, reducing the risk of shifting between the upper elastic element 23 and the lower movable element 3. In other alternative embodiments, the upper elastic element 23 can also be other elastic elements.

[0077] As a preferred implementation method, such as Figure 3 As shown, the top of the upper housing 22 has an inward / outward bending portion 221, and the upper housing 22 is connected to the heat collection plate 21 through the bending portion 221. The above arrangement increases the connection area between the upper housing 22 and the heat collection plate 21, thereby improving the reliability of the connection between the upper housing 22 and the heat collection plate 21.

[0078] In this embodiment, the edge of the heat collection plate 21 is bent outward, the top of the upper shell 22 has an inward bent portion 221, and there is an annular connecting surface between the upper shell 22 and the heat collection plate 21, which is beneficial to the reliability of the connection between the upper shell 22 and the heat collection plate 21.

[0079] As a preferred implementation method, such as Figures 1-3 As shown, the bottom end of the upper housing 22 has a first support portion 222 extending inward / outward, and the upper housing 22 is supported on the lower movable member 3 through the first support portion 222. This arrangement increases the contact area between the upper housing 22 and the lower movable member 3. In particular, when the upper movable member 2 moves horizontally and / or swings, the upper housing 22 can still be supported on the lower movable member 3 through the first support portion 222, ensuring that there is a fulcrum for supporting the upper housing 22 between the upper housing 22 and the lower movable member 3, which is beneficial for the normal use of the probe assembly.

[0080] In this embodiment, the bottom end of the upper housing 22 has an inwardly extending first support portion 222, which increases the contact area between the upper housing 22 and the lower movable member 3. At the same time, the upper housing 22 has a large inner diameter, which facilitates the installation of the upper elastic member 23 and is beneficial to the assembly of the probe assembly.

[0081] As a preferred implementation method, such as Figures 1-3As shown, the probe assembly includes an upper protective shell 24, which is connected to the upper housing 22 and spaced apart from the outer wall of the upper housing 22 in the circumferential direction. The upper protective shell 24 extends at least part of the upper movable member 2 in the axial direction of the upper housing 22. When the burner is operating, it generates high-temperature flue gas, which can cause thermal interference to the temperature probe 1. The above-mentioned design prevents the high-temperature flue gas from approaching the upper movable member 2, which is beneficial for the accurate temperature measurement of the temperature probe 1, reduces the risk of false readings by the temperature probe 1 leading to accidental burner shutdown, and improves the user experience of the probe assembly. Simultaneously, the above-mentioned design reduces the working environment of the upper elastic member 23, increasing its service life.

[0082] In this embodiment, the top of the upper protective shell 24 is bent inward and fixed to the outer side wall of the upper housing 22. The upper protective shell 24 extends from the top of the upper housing 22 to the bottom of the upper housing 22. Here, the axial extension range of the upper protective shell 24 in the upper housing 22 is not specifically limited. In other alternative embodiments, the upper protective shell 24 may extend only to a portion of the upper movable member 2, or it may extend to the lower movable member 3. It should be noted that when the probe assembly is mounted on the burner, the arrangement of the upper protective shell 24 preferably does not affect the vertical movement of the temperature probe 1.

[0083] As a preferred implementation method, such as Figure 2 As shown, the lower movable component 3 includes a lower housing 31, a lower elastic component 32, and a support rod 33. The bottom end of the lower elastic component 32 acts on the support rod 33, and the top end of the lower elastic component 32 acts on the lower housing 31. The upper movable component 2 is mounted on the lower housing 31, and the lower housing 31 is movable in the vertical direction. When the cookware is placed on the burner, the cookware exerts downward pressure on the probe assembly. This downward pressure is transmitted to the top of the lower housing 31 through the upper movable component 2. The support rod 33 is fixed relative to the burner, and the lower elastic component 32 is compressed, making the height of the probe assembly adjustable. The probe assembly can be used with cookware of different shapes, which is beneficial to the user experience. When the cookware is removed, the restoring force of the lower elastic component 32 causes the lower movable component 3 to return to its initial state, eliminating the need for the user to readjust the lower movable component 3 and facilitating the use of the probe assembly.

[0084] In this embodiment, the lower elastic element 32 is a spring. The top end of the support rod 33 extends outward so that the bottom end of the lower elastic element 32 can act on the support rod 33, and the top end of the lower elastic element 32 acts on the top end of the lower housing 31. The lower housing 31 moves vertically by the expansion and contraction of the lower elastic element 32. The lower elastic element 32 is mounted on the support rod 33. In a preferred embodiment, the bottom end of the lower elastic element 32 can be fixed to the support rod 33 by welding, bonding, or other methods to reduce the risk of the lower elastic element 32 shifting relative to the support rod 33. In other alternative embodiments, the lower elastic element 32 can also be other elastic components.

[0085] As a preferred implementation method, such as Figure 2 and Figure 4 As shown, the bottom of the lower housing 31 has an inwardly bent limiting part 311, which abuts against the support rod 33 to prevent the support rod 33 from detaching from the lower housing 31. This design improves the reliability of the connection between the lower housing 31 and the support rod 33, facilitating the installation and use of the probe assembly.

[0086] In this embodiment, the limiting part 311 bends inward circumferentially along the bottom of the lower housing 31, and the top end of the support part extends outward. In other alternative embodiments, a groove may also be provided on the support rod 33 in a vertical direction, in which the limiting part 311 can slide, wherein the top end of the groove can limit the highest position that the limiting part 311 can reach.

[0087] As a preferred implementation method, such as Figure 2 and Figure 3 As shown, the top of the lower housing 31 has a second support portion 312 extending inward / outward, and the bottom end of the upper movable member 2 is mounted on the second support portion 312. This arrangement increases the contact area between the lower housing 31 and the upper movable member 2. In particular, when the upper movable member 2 moves horizontally and / or swings, it can still be mounted on the lower housing 31 via the second support portion 312, ensuring that there is a fulcrum for supporting the upper movable member 2 between the upper movable member 2 and the lower housing 31, which is beneficial for the normal use of the probe assembly.

[0088] In this embodiment, the top end of the lower housing 31 has an inwardly extending second support portion 312, and the top end of the upper housing 22 has an inwardly extending first support portion 222. This increases the annular contact area between the upper movable member 2 and the lower movable member 3. At the same time, the above arrangement makes the lower housing 31 have a larger inner diameter, which facilitates the installation of the lower elastic member 32 and is beneficial to the assembly of the probe assembly.

[0089] As a preferred implementation method, such as Figure 2 and Figure 3As shown, the second support portion 312 is L-shaped, and the probe assembly includes a wire 4 that passes through the second support portion 312. The top end of the lower elastic member 32 is sleeved on the second support portion 312. The second support portion 312 has a horizontal portion and a vertical portion. The horizontal portion extends inward along the top of the lower housing 31, and the vertical portion is located inside the horizontal portion and extends downward. The vertical portion forms a cylindrical shape, and the inner wall of the cylindrical structure formed by the vertical portion is attached to the outer surface of the wire 4 to restrict the movement of the wire 4 inside the upper housing 22 and the lower housing 31. The wire 4 passes through the second support portion 312, reducing the risk of the wire 4 getting tangled inside the upper housing 22 or the lower housing 31, and providing space for the horizontal movement and / or swing of the upper movable member 2. The top of the lower elastic member 32 is sleeved on the outside of the vertical portion. The vertical portion limits the top of the lower elastic member 32. The lower elastic member 32 acts on the horizontal portion, reducing the risk of the lower elastic member 32 shifting, and realizing that the lower elastic member 32 deforms in the vertical direction, which is beneficial to the assembly and use of the probe assembly.

[0090] As a preferred implementation method, such as Figure 2 , Figure 4 and Figure 5 As shown, the lower housing 31 has at least one guide portion 313, and the support rod 33 has at least one matching portion 331. The matching portion 331 corresponds one-to-one with the guide portion 313, and the matching portion 331 slides on the guide portion 313 to realize the vertical movement of the lower housing 31. This arrangement enables the lower housing 31 to move vertically and restricts its horizontal movement or rotation, thereby ensuring that the lower elastic member 32 is only subjected to vertical force and deforms only in the vertical direction. This reduces the risk of deformation and reduced deformation range caused by horizontal force on the lower elastic member 32, thus improving the adaptability of the probe assembly and facilitating its use.

[0091] In this embodiment, three guide portions 313 are provided on the side wall of the lower housing 31, and the guide portions 313 are spaced apart circumferentially along the lower housing 31. The structure of the guide portions 313 is a recessed structure extending inward in the vertical direction. A matching portion 331 is provided on the top of the support rod 33, and the structure of the matching portion 331 matches the structure of the guide portions 313. The matching portion 331 extends outward along the outer side wall of the support rod 33, and can also be used to restrict the support rod 33 from detaching from the lower housing 31 and to provide the lower elastic member 32, thus simplifying the structure of the support rod 33.

[0092] Example 2

[0093] The probe assembly in this embodiment has a similar structure to the probe assembly in embodiment 1. The main difference is that the lower movable part 3 in this embodiment also includes a connector 34 and a lower protective shell 35.

[0094] In specific implementation, such as Figure 6 and Figure 7 As shown, the connector 34 is disposed between the upper movable member 2 and the lower housing 31. The probe assembly includes a wire 4. The inner diameter of the connector 34 is smaller than the inner diameter of the lower housing 31. The wire 4 passes sequentially through the lower movable member 3, the connector 34, and the upper movable member 2, and is connected to the temperature probe 1. This arrangement restricts the movement of the wire 4 between the first or second movable member. The connector 34 is fixed to the lower housing 31 by welding, riveting, threading, or other connection methods, or it can be integrally formed with the lower housing 31. In a preferred embodiment, the inner wall surface of the connector 34 is in contact with the outer surface of the wire 4 to restrict the movement of the wire 4 inside the upper housing 22 and the lower housing 31, reducing the risk of the wire 4 becoming entangled inside the upper housing 22 or the lower housing 31, providing space for the horizontal movement and / or swinging of the upper movable member 2, which is beneficial for the use of the probe assembly.

[0095] As a preferred implementation method, such as Figure 6 and Figure 7 As shown, the top of the connector 34 has an outwardly extending third support portion 341, on which the upper movable member 2 is mounted. This arrangement increases the contact area between the lower housing 31 and the upper movable member 2. Specifically, when the upper movable member 2 moves horizontally and / or swings, it can still be mounted on the lower housing 31 via the third support portion 341, ensuring that there is a fulcrum for supporting the upper movable member 2 between them. This facilitates the normal use of the probe assembly.

[0096] As a preferred implementation method, such as Figure 6 and Figure 7 As shown, the lower protective shell 35 is connected to the lower housing 31 and is spaced apart from the outer side wall of the lower housing 31 in the circumferential direction. The lower protective shell 35 extends at least part of the lower movable member 3 in the axial direction of the lower housing 31. When the burner is working, it will generate high-temperature flue gas, which will cause thermal interference to the temperature probe 1. Through the above-mentioned arrangement, the high-temperature flue gas can be prevented from approaching the lower movable member 3, reducing the working environment of the lower elastic member 32 and increasing the service life of the lower elastic member 32.

[0097] In this embodiment, the top of the lower protective shell 35 is bent inward and connected to the outer wall of the lower housing 31 in the circumferential direction. The lower protective shell 35 extends from the top of the lower housing 31 to the bottom of the lower housing 31. In this embodiment, the probe assembly also includes an upper protective shell 24. The outer diameter of the lower protective shell 35 is smaller than the inner diameter of the upper protective shell 24 to avoid interfering with the horizontal movement and / or swinging of the upper movable part 2. Here, there are no specific limitations on the axial extension range of the lower protective shell 35 in the lower housing 31 or the connection position of the lower protective shell 35 relative to the lower housing 31. It should be noted that when the probe assembly is installed on the burner, the arrangement of the lower protective shell 35 preferably does not affect the vertical movement of the temperature probe 1.

[0098] Example 3

[0099] The probe assembly in this embodiment has a similar structure to the probe assembly in Embodiment 1. The main difference is that in this embodiment, the probe assembly includes an additional movable component, which is positioned between the upper movable component 2 and the lower movable component 3. The additional movable component is movable relative to the lower movable component 3 and the upper movable component 2. By providing the additional movable component, which is movable relative to the lower movable component 3 and the upper movable component 2, the range of motion of the temperature probe 1 in both the vertical and horizontal directions is increased. This improves the adaptability of the probe assembly to cookware of different shapes. Furthermore, when the cookware moves horizontally, the temperature probe 1 can still fit against the bottom of the cookware for temperature measurement, reducing the risk of the temperature probe 1 failing to contact the bottom of the cookware and improving the user experience.

[0100] In this embodiment, the number of additional movable parts can be set to one or more, and each additional movable part can realize movement modes such as vertical extension, horizontal movement and / or swinging, rotation, etc.

[0101] Example 4

[0102] This embodiment provides a burner that includes any one of the probe components described in embodiments 1-3 above. During cooking, the pot is placed on the burner, and the temperature probe 1 is in contact with the bottom of the pot to measure its temperature. When the pot is dry-burning or the bottom temperature is too high, the burner can be shut off in time, reducing the risk of dry burning. The upper movable part 2 can move horizontally and / or swing relative to the lower movable part 3. By setting the upper movable part 2, when the pot moves horizontally, such as when the user actively shakes the pot by swishing the pot to heat oil, swishing the pot to stir, tossing the pot to stir, or moving the pot to pour food; or when the pot shakes passively due to sliding on the pot rack or being placed off-center, the temperature probe 1 can still be in contact with the bottom of the pot to measure the temperature, reducing the risk of the temperature probe 1 not being able to contact the bottom of the pot, reducing the risk of the burner being accidentally turned off, and improving the user experience.

[0103] While specific embodiments of the present invention have been described above, those skilled in the art should understand that these are merely illustrative examples, and the scope of protection of the present invention is defined by the appended claims. Those skilled in the art can make various changes or modifications to these embodiments without departing from the principles and essence of the present invention, but all such changes and modifications fall within the scope of protection of the present invention.
