Abstract
Description
[0001] This application claims priority to Chinese Patent Application No. 2024206985805, filed on April 7, 2024. The entire contents of the aforementioned patent application are incorporated herein by reference. Technical Field
[0002] This utility model relates to the field of stove technology, and in particular to a temperature sensing probe assembly and a stove containing the same. Background Technology
[0003] Most cooktops on the market are equipped with temperature sensors to prevent dry burning. However, these sensors are often fixed in height or have poor height adjustment, leading to frequent false triggers or malfunctions when using cookware with different bottom shapes. For example, when using a concave pot with a very large indentation, the high-temperature fumes around the sensor may quickly trigger the dry-burn protection because the sensor cannot reach the bottom, affecting normal use. Conversely, when using a pointed pot with a very convex bottom, the bottom of the pot may completely contact the sensor, or the retractable sensor tip may be completely compressed while other parts of the pot are not yet in contact with the pot support, rendering the pot unusable or risking slippage or tipping if used improperly. Utility Model Content
[0004] The technical problem to be solved by this utility model is to overcome the defect of poor adjustability of temperature probe height in the prior art, and to provide a temperature probe assembly and a stove containing the same.
[0005] The present invention solves the above-mentioned technical problems through the following technical solution:
[0006] A temperature sensing probe assembly is applied to a stove and acts on the bottom of a pot. The temperature sensing probe assembly includes a temperature sensing probe, a driving part, a first detection component, and a controller. One end of the temperature sensing probe is located at the bottom of the pot.
[0007] The other end of the head is connected to the drive part, which is used to drive the temperature probe to move in the vertical direction; both the first detection component and the drive part are electrically connected to the controller; the first detection component is used to detect the force on the temperature probe, and the controller is used to receive the detection signal value emitted by the first detection component and compare it with a set value to control the opening and closing of the drive part.
[0008] In this solution, with the above-described structure, when the cookware is placed above the temperature probe, the force acting on the temperature probe can be detected by the first detection component. The controller sends a corresponding control command to the controller based on the detection signal value of the first detection component to control the opening and closing of the drive part. When the drive part is turned on, the controller determines whether the drive part drives the temperature probe to rise or fall, thereby improving the adjustability of the temperature probe height. For example, when a concave pot with a very large indentation is placed above the temperature sensor, the temperature sensor cannot contact the bottom of the pot. The first detection component detects that the force on the temperature sensor is zero. At this time, the controller can send a signal to the drive unit to open and drive the temperature sensor to rise, so that the temperature sensor can contact the bottom of the pot and be used normally. When a pot with a very convex bottom is placed above the temperature sensor, the temperature sensor contacts the bottom of the pot, but the pot cannot be completely placed on the pot support. A preset value can be set. When the first detection component detects that the force on the temperature sensor is greater than the preset value, the controller can send a signal to the drive unit to open and drive the temperature sensor to descend, so that the temperature sensor can descend. Under the premise of ensuring that the temperature sensor contacts the bottom of the pot, the pot can be placed on the pot support for easy use by the user. When the first detection component detects that the force on the temperature sensor is greater than zero but less than the preset value, it can be determined that the bottom of the pot is in contact with the temperature sensor and can be used normally. At this time, the controller controls the drive unit to shut down, and the temperature sensor does not need to rise or fall.
[0009] Preferably, the temperature sensing probe assembly further includes a timing component, which is electrically connected to the controller; the timing component is used to detect the start-up time of the stove, and the controller is used to receive the detection signal value emitted by the timing component and compare it with a set value to control the on / off state of the drive section.
[0010] In this solution, a timing component that detects the start-up time of the stove provides a starting point for the detection of the first detection component. Working in conjunction with the first detection component, it automatically identifies or determines the type of cookware, enabling the controller to issue more appropriate control commands. For example, when the user places the cookware on the temperature probe and starts the stove, the timing component begins timing. When the timing component detects that the stove's start-up time exceeds a predetermined value, ensuring that the user has completed placing the cookware, and the first detection component detects that the force on the temperature probe is still zero, it determines that the cookware is a concave-bottomed pot. At this point, the controller then controls the drive unit to raise the temperature probe.
[0011] Preferably, the temperature sensing probe includes a probe body and a temperature measuring element. One end of the probe body is connected to the driving part, and the temperature measuring element is slidably sleeved on the end of the probe body away from the driving part in the vertical direction. The temperature measuring element is used to abut against the bottom of the pot. The first detection component is used to detect the force applied to the probe body.
[0012] In this solution, the temperature sensing element can be slidably mounted on the end of the probe body away from the drive part in the up-down direction, so that the temperature sensing element itself, which is close to and in contact with the bottom of the pot, has a certain displacement. When the user uses a pot with a normal shape, the bottom of the pot contacts the temperature sensing element, and the temperature sensing element is pressed and slid down on the probe body. Since the temperature sensing element is connected to the probe body, the first detection component can detect the force applied to the probe body. At this time, there is no need to control the drive part to drive the temperature sensing probe to rise or fall, so that the pot and the temperature sensing probe can be used normally, avoiding unnecessary start-up of the drive part.
[0013] Preferably, the temperature sensing probe assembly further includes a second detection component, which is electrically connected to the controller; the second detection component is used to detect the displacement of the temperature sensing element relative to the probe body, and the controller is used to receive the detection signal value emitted by the second detection component and compare it with a set value to control the opening and closing of the drive section.
[0014] In this solution, a second detection component is incorporated to detect the displacement of the temperature sensor relative to the probe body. This component works in conjunction with the first detection component and the timing component to enable the controller to issue more precise control commands. For example, when the timing component detects that the stove's start-up time exceeds a predetermined value, and the second detection component detects that the displacement of the temperature sensor relative to the probe body has reached its maximum value, it indicates that the user is using a pot with a prominent convex bottom, and the bottom of the pot has completely pressed the temperature sensor down to a position where it cannot move. At this point, the controller controls the drive unit to lower the temperature sensor. Furthermore, the second detection component also provides a reference for stopping the drive unit. For instance, if the user is using a pot with a prominent convex bottom, during the process of the controller controlling the drive unit to lower the temperature sensor, if the first detection component detects that the temperature sensor is under force and the second detection component detects that the displacement of the temperature sensor relative to the probe body is less than the maximum value, it indicates that the temperature sensor has descended a distance sufficient to place the pot stably and maintain contact between the temperature sensor and the bottom of the pot, allowing the user to use the appliance normally. At this point, the controller can shut down the drive unit, stopping the further downward movement of the temperature sensor. Therefore, the overall control logic of the controller is more comprehensive and rigorous.
[0015] Preferably, the temperature probe assembly further includes a mounting housing, and the driving part includes a driver and a transmission mechanism; the driver is disposed inside the mounting housing, one end of the transmission mechanism is connected to the driver, and the other end of the transmission mechanism extends out of the mounting housing and is connected to the temperature probe, so as to transmit the driving force of the driver to the temperature probe.
[0016] In this design, the mounting housing provides the mounting base for the actuator and transmission mechanism. The actuator serves as the power source, and the transmission mechanism transmits the driving force of the actuator to the temperature sensor, thereby achieving energy conversion.
[0017] Preferably, the transmission mechanism includes a first gear, a second gear, and a screw; the first gear is connected to the driver, the first gear and the second gear mesh, one end of the screw is rotatably connected to the second gear, the other end of the screw extends out of the mounting housing and is connected to the temperature sensor, and the screw extends in the vertical direction.
[0018] In this scheme, the first gear is connected to the driver, converting the driving force of the driver into the rotation of the first gear. The first gear and the second gear mesh, and the rotation of the first gear can drive the rotation of the second gear. The second gear is connected to one end of the screw, and the rotation of the second gear drives the screw to move in the up and down direction, thereby driving the temperature probe connected to the screw to move in the up and down direction.
[0019] Preferably, there are multiple screws arranged around the first gear; and / or, the bottom of the temperature sensor is connected to a base, and the base has a receiving cavity on the side opposite to the temperature sensor; the end of the screw away from the first gear is rotatably disposed in the receiving cavity.
[0020] In this design, multiple screws are arranged around the first gear, allowing the temperature probe connected to the screws to receive more sufficient driving force. A base is connected to the bottom of the temperature probe, which expands the connection area of the temperature probe, allowing multiple screws to connect to the temperature probe through the base, resulting in more balanced force distribution. In addition, the end of the screw away from the first gear is rotatably disposed in a receiving cavity on the side of the base opposite to the temperature probe, allowing the screw to connect with the base during its rotation, thereby driving the base to rise or fall.
[0021] Preferably, the temperature probe assembly further includes an adjustment component, one side of which is connected to the drive portion, and the other side of which has an upward-opening mounting cavity. The inner peripheral wall of the mounting cavity has a plurality of slots arranged in a vertical direction. The end of the temperature probe near the drive portion is located in the mounting cavity, and the outer peripheral wall of the end of the temperature probe near the drive portion has a protrusion that can be selectively engaged with one of the plurality of slots.
[0022] In this design, multiple slots arranged vertically form height adjustment positions. The temperature sensor is installed inside the adjustment component, and the protrusion of the temperature sensor can be selected to snap into one of the multiple slots, making the fixed height of the temperature sensor adjustable. This further enhances the height adjustability of the temperature sensor and facilitates compatibility with different heights of stove bases, pedestals, pot supports, and other devices, increasing the versatility of the temperature sensor assembly.
[0023] Preferably, the temperature sensing probe assembly further includes a base connected above the driving part; the adjusting member is disposed above the base and has a connecting hole extending in the vertical direction; the base has a mating hole corresponding to the position of the connecting hole, and the connecting hole and the mating hole are connected by threads; and / or, the first detection component is a gravity sensor disposed inside the base.
[0024] In this design, by providing connecting holes extending vertically along the adjusting component, the adjusting component and the base can be connected and fixed vertically. When the temperature sensor needs maintenance or replacement, simply unscrew the screws or bolts securing the adjusting component from the secondary air inlet in the center of the burner cap, moving vertically along the same direction, to remove the adjusting component and temperature sensor from the base for replacement, reducing the difficulty of disassembly and assembly. Furthermore, a gravity sensor can be used as the primary detection component. By detecting the gravity value of the temperature sensor, it can be determined whether the temperature sensor is in contact with the cookware. The base, located below the temperature sensor, provides an installation foundation for the gravity sensor and allows for detection of the temperature sensor's gravity value at a suitable location.
[0025] A cooktop that includes a temperature sensing probe assembly as described above.
[0026] The positive and progressive effects of this utility model are as follows:
[0027] In this invention, when the cookware is placed above the temperature probe, the force acting on the temperature probe can be detected by the first detection component. The controller sends a corresponding control command to the controller based on the detection signal value of the first detection component to control the opening and closing of the drive part. When the drive part is turned on, the controller determines whether the drive part drives the temperature probe to rise or fall, thereby improving the adjustability of the temperature probe height.

[0058] The present invention will be described more clearly and completely below with reference to the accompanying drawings, using a preferred embodiment.
[0059] like Figure 1 , Figure 2 and Figure 7 As shown in the figure, this embodiment provides a stove that includes a temperature sensing probe assembly.
[0060] A temperature sensing probe assembly is applied to the cooktop and acts on the bottom of the pot. The temperature sensing probe assembly includes a temperature sensing probe 200, a drive unit 600, a first detection component 710, and a controller 700. One end of the temperature sensing probe 200 is located at the bottom of the pot, and the other end of the temperature sensing probe 200 is connected to the drive unit 600. The drive unit 600 is used to drive the temperature sensing probe 200 to move in the vertical direction. Both the first detection component 710 and the drive unit 600 are electrically connected to the controller 700. The first detection component 710 is used to detect the force applied to the temperature sensing probe 200, and the controller 700 is used to receive the detection signal value emitted by the first detection component 710 and compare it with a set value to control the opening and closing of the drive unit 600.
[0061] See Figure 1The temperature sensor 200 extends from the secondary air inlet 110 in the middle of the burner cap 100, so that it contacts the bottom of the cookware when it is placed above the burner cap 100. When the cookware is placed above the temperature sensor 200, the force acting on the temperature sensor 200 can be detected by the first detection component 710. The controller 700 sends a corresponding control command to the controller 600 based on the detection signal value of the first detection component 710 to control the opening and closing of the drive part 600. When the drive part 600 is turned on, the controller determines whether the drive part 600 drives the temperature sensor 200 to rise or fall, thereby improving the adjustability of the height of the temperature sensor 200. When a concave pot with a particularly large indentation is placed above the temperature probe 200, the temperature probe 200 cannot contact the bottom of the pot. The first detection component 710 detects that the force on the temperature probe 200 is zero. At this time, the controller 700 can send a signal to the drive component 600 to open and drive the temperature probe 200 to rise, so that the temperature probe 200 can contact the bottom of the pot and be used normally. When a pot with a particularly convex bottom is placed above the temperature probe 200, the temperature probe 200 contacts the bottom of the pot, but the pot cannot be completely placed on the pot support. A preset value can be set so that when the first detection component 710 detects that the temperature probe 200 is subjected to zero force, the temperature probe 200 can contact the bottom of the pot. When the force exerted on the temperature sensor 200 exceeds the set value, the controller 700 sends a signal to the drive unit 600 to activate and drive the temperature sensor 200 to descend, allowing the temperature sensor 200 to descend. This ensures the temperature sensor 200 is in contact with the bottom of the cookware, allowing the cookware to be placed on the cookware support for user convenience. When the first detection unit 710 detects that the force exerted on the temperature sensor 200 is greater than zero but less than the set value, it determines that the bottom of the cookware is in contact with the temperature sensor 200 and is usable. In this case, the controller 700 controls the drive unit 600 to shut down, and the temperature sensor 200 does not need to rise or fall.
[0062] Furthermore, the temperature sensing probe assembly also includes a timing component 720, which is electrically connected to the controller 700. The timing component 720 is used to detect the start-up time of the stove, and the controller 700 is used to receive the detection signal value emitted by the timing component 720 and compare it with the set value to control the opening and closing of the drive section 600.
[0063] By setting a timing component 720 to detect the start-up time of the stove, a time starting point is provided for the detection of the first detection component 710. Working in conjunction with the first detection component 710, it automatically identifies or determines the type of cookware, enabling the controller 700 to issue more appropriate control commands. When the user places the cookware on the temperature probe 200 and starts the stove, the timing component 720 starts timing. When the timing component 720 detects that the start-up time of the stove exceeds a certain predetermined value, ensuring that the user has completed the operation of placing the cookware, and the first detection component 710 detects that the force on the temperature probe 200 is still zero, it determines that the cookware is a concave-bottomed pot. At this time, the controller 700 then controls the drive unit 600 to drive the temperature probe 200 to rise.
[0064] In other alternative implementations, a start button can be set to manually activate the first detection component 710 to start detecting the force on the temperature probe 200; or the cookware can be placed in place by detecting whether force is detected on the pot support, thus providing a time starting point for the detection of the first detection component 710.
[0065] like Figure 2 and Figure 4 As shown, the temperature probe 200 includes a probe body 220 and a temperature measuring element 210. One end of the probe body 220 is connected to the driving part 600. The temperature measuring element 210 is slidably sleeved on the end of the probe body 220 away from the driving part 600 in the up-down direction. The temperature measuring element 210 is used to abut against the bottom of the pot. The first detection component 710 is used to detect the force applied to the probe body 220.
[0066] The temperature measuring element 210 can be slidably sleeved on the end of the probe body 220 away from the drive part 600 in the up and down direction, so that the temperature measuring element 210, which is close to and in contact with the bottom of the pot, has a certain displacement. When the user uses a pot with a normal shape, the bottom of the pot contacts the temperature measuring element 210 and presses the temperature measuring element 210 to slide on the probe body 220 (downward). Since the temperature measuring element 210 is connected to the probe body 220, the first detection component 710 can detect that the probe body 220 is subjected to force. At this time, there is no need to control the drive part 600 to drive the temperature sensing probe 200 to rise or fall, so that the pot and the temperature sensing probe 200 can be used normally, avoiding unnecessary start-up of the drive part 600.
[0067] In this embodiment, the temperature measuring element 210 is internally connected to the probe body 220 via a spring. This allows the temperature measuring element 210 to move downwards under spring compression when its top is pressed, and to return to its original position under spring force when the top is not pressed, thus achieving vertical displacement. In other optional embodiments, the temperature measuring element 210 can also be displaced relative to the probe body 220 by using elastic rubber or by making the temperature measuring element 210 and probe body 220 into a telescopic rod configuration.
[0068] Furthermore, the temperature sensing probe assembly also includes a second detection component 730, which is electrically connected to the controller 700. The second detection component 730 is used to detect the displacement of the temperature sensing element 210 relative to the probe body 220. The controller 700 is used to receive the detection signal value emitted by the second detection component 730 and compare it with the set value to control the opening and closing of the drive section 600.
[0069] Understandably, in this embodiment, the temperature sensing element 210 is fitted onto the end of the probe body 220, and its displacement relative to the probe body 220 is limited (or, the downward displacement of the temperature sensing element 210 after being pressed is limited). By setting a second detection component 730 to detect the displacement of the temperature sensing element 210 relative to the probe body 220, in conjunction with the first detection component 710 and the timing component 720, the controller 700 can issue more precise control commands. For example, when the timing component 720 detects that the start-up time of the stove exceeds a certain predetermined value, and the second detection component 730 detects that the displacement of the temperature sensing element 210 relative to the probe body 220 has reached its maximum value, it indicates that the user is using a pot with a prominent convex bottom, and the bottom of the pot has completely pressed the temperature sensing element 210 down to a position where it cannot move. At this time, the controller 700 controls the drive component 600 to drive the temperature sensing probe 200 to descend. Furthermore, the second detection component 730 can also provide a reference for stopping the drive component. When the user uses a pot with a prominent convex bottom, during the process of the controller 700 controlling the drive component 600 to lower the temperature probe 200, if the first detection component 710 detects that the temperature probe 200 is subjected to force and the second detection component 730 detects that the displacement of the temperature measuring element 210 relative to the probe body 220 is less than the maximum value, it indicates that the distance the temperature probe 200 has descended is sufficient to place the pot stably and maintain contact between the temperature measuring element 210 and the bottom of the pot, allowing the user to use the pot normally. At this time, the controller 700 can control the drive component 600 to shut down, stopping the further downward movement of the temperature probe 200. Thus, the overall control logic of the controller 700 is more comprehensive and rigorous.
[0070] Specifically, in this embodiment, the first detection component 710, the second detection component 730 and the timing component 720 are used simultaneously, and the control process is as follows:
[0071] The user starts the cooking appliance (i.e., ignites it), the timing component 720 detects and records the moment t0, and the first detection component 710 and the second detection component 730 start to detect the force g1 received by the probe body 220 and the displacement amount x1 of the temperature measuring element 210 relative to the probe body 220 in real time, and transmit the detection value signals to the controller 700. After a period of time (to ensure that the user has placed the cookware above the burner 100 or on the pot support), the timing component 720 detects and records the moment t1.
[0072] When t1 - t0 > 1 min and g1 = 0, it indicates that the temperature sensing probe 200 is not stressed and the bottom of the cookware does not contact the temperature measuring element 210 of the temperature sensing probe 200. It is determined that the user is using a concave pot with a very large concave degree. The controller 700 controls the drive part 600 (the driver 610 therein) to start and makes the drive part 600 drive the temperature sensing probe 200 to rise to contact the bottom of the cookware. After a certain time, the temperature measuring element 210 of the temperature sensing probe 200 contacts the bottom of the cookware, the temperature sensing probe 200 is stressed and the temperature measuring element 210 is displaced relative to the probe body 220. Then when g1 > 0 and x1 > 0, the controller 700 controls the drive part 600 to stop, and the temperature sensing probe 200 no longer rises. The user can use the cookware normally, and the temperature sensing probe 200 can also play the role of dry-burning prevention protection normally. When the user finishes cooking and turns off the fire, the timing component 720 can no longer detect the start time of the cooking appliance and sends a reset signal to the controller 700. The controller 700 controls the drive part 600 to start and makes the drive part 600 drive the temperature sensing probe 200 to descend to the starting position.
[0073] When t1 - t0 > 1 min, g1 > 0 and x1 = a (a is the maximum displacement amount of the temperature measuring element 210 relative to the probe body 220), it indicates that the bottom of the cookware contacts the temperature measuring element 210 of the temperature sensing probe 200 and presses the temperature measuring element 210 down to a position where it cannot move down any further. It is determined that the user is using a pointed-bottom pot with a very large protruding degree. The controller 700 controls the drive part 600 to start and makes the drive part 600 drive the temperature sensing probe 200 to descend so that the cookware can be placed normally. When the temperature sensing probe 200 as a whole descends to a certain position, the cookware is placed normally, the pressure on the temperature measuring element 210 begins to relieve, and it can be displaced relative to the probe body 220 again (in the upward direction). Then when g1 > 0 and x1 < a, the controller 700 controls the drive part 600 to stop, and the temperature sensing probe 200 no longer descends. When the user finishes cooking and turns off the fire, the timing component 720 can no longer detect the start time of the cooking appliance and sends a reset signal to the controller 700. The controller 700 controls the drive part 600 to start and makes the drive part 600 drive the temperature sensing probe 200 to rise to the starting position.
[0074] When t1 - t0 > 1 min, g1 > 0 and x1 < a, it indicates that the bottom of the cookware contacts the temperature measuring element 210 of the temperature sensing probe 200 and presses down the temperature measuring element 210. However, the degree of downward movement of the temperature measuring element 210 is still within its maximum downward movement range, and it is determined that the user is using an ordinary cookware (such as a flat pan, a concave pan with a small inner concavity, a pointed pan with a small outer convexity, etc.). At this time, it can be used normally, and the controller 700 does not need to control the driving part 600 to start.
[0075] In addition, in Chinese cooking, high - fire stir - frying and tossing the pan are often used. As the cookware is continuously picked up and put down, the value of the force g1 detected by the first detection component 710 on the probe body 220 will rapidly change periodically. The controller 700 can thus determine that the user is in the state of tossing the pan, and control the cooking appliance not to enter the fire - cutting program or automatically increase the dry - burning prevention threshold to avoid accidental fire - turning - off and accidental fire - cutting, ensuring the normal use of the user.
[0076] As Figure 2 [[ID=1,0]]and [[ID=,11]] Figure 3 shown, the temperature sensing probe assembly further includes a mounting shell 500, and the driving part 600 includes a driver 610 and a transmission mechanism; the driver 610 is arranged inside the mounting shell 500, one end of the transmission mechanism is connected to the driver 610, and the other end of the transmission mechanism extends out of the mounting shell 500 and is connected to the temperature sensing probe 200 to transmit the driving force of the driver 610 to the temperature sensing probe 200. The mounting shell 500 provides a mounting basis for the arrangement of the driver 610 and the transmission mechanism. The driver 610 is the power source, and through the transmission mechanism, the driving force of the driver 610 is transmitted to the temperature sensing probe, realizing energy conversion.
[0077] Specifically, the transmission mechanism includes a first gear 620, a second gear 640 and a screw 630; the first gear 620 is connected to the driver 610, the first gear 620 and the second gear 640 are meshed, one end of the screw 630 is rotatably connected to the second gear 640, the other end of the screw 630 extends out of the mounting shell 500 and is connected to the temperature sensing probe 200, and the screw 630 extends along the up - down direction.
[0078] In this embodiment, the screw 630 and the second gear 640 are connected by a lead screw. In other embodiments, other connection methods considered suitable by those skilled in the art can also be used to convert the rotation of the second gear 640 into the up - down movement of the screw 630.
[0079] The first gear 620 is connected to the driver 610, converting the driving force of the driver 610 into the rotation of the first gear 620. The first gear 620 is meshed with the screw 630 extending along the up - down direction, driving the screw 630 to move along the up - down direction, and further driving the temperature sensing probe 200 connected to the screw 630 to move along the up - down direction.
[0080] Furthermore, there are multiple screws 630, which are arranged around the first gear 620, so that the temperature probe 200 connected to the screws 630 can obtain more sufficient driving force.
[0081] In this embodiment, the driver 610 is a motor, the first gear 620 extends horizontally, and four screws 630 are evenly spaced around the first gear 620. In other alternative embodiments, the driver 610 can be any existing device capable of serving as a power source; the number of screws 630 can also be different. Of course, the transmission mechanism may not be configured with the cooperation of the first gear 620, the second gear 640, and the screws 630; other lifting mechanisms can also be used.
[0082] Furthermore, the bottom of the temperature probe 200 is connected to a base 400, and the base 400 has a receiving cavity 410 on the side away from the temperature probe 200; the end of the screw 630 away from the first gear 620 is rotatably disposed in the receiving cavity 410.
[0083] The base 400 increases the connection area of the temperature probe 200, allowing multiple screws 630 to be connected to the temperature probe 200 through the base 400, resulting in more balanced force distribution. In addition, the end of the screw 630 away from the first gear 620 is rotatably disposed in the receiving cavity 410 provided on the side of the base 400 away from the temperature probe 200, so that the screw 630 can connect with the base 400 during its own rotation, thereby driving the base 400 to rise or fall.
[0084] The screw 630 and the receiving cavity 410 can be connected by threads to enable the screw 630 to rotate, or the receiving cavity 410 can be provided with a smooth inner peripheral wall to enable the screw 630 to rotate.
[0085] like Figure 2 , Figures 4-6 As shown, the temperature probe assembly also includes an adjustment component 300. One side of the adjustment component 300 is connected to the drive part 600, and the other side of the adjustment component 300 has an upward-opening mounting cavity 310. The inner peripheral wall of the mounting cavity 310 has a plurality of slots 320 arranged in the vertical direction. The end of the temperature probe 200 near the drive part 600 is located in the mounting cavity 310, and the outer peripheral wall of the end of the temperature probe 200 near the drive part 600 has a protrusion 230, which can be selectively engaged with one of the plurality of slots 320.
[0086] Multiple slots 320 arranged in the vertical direction form a height adjustment range. The temperature probe 200 is installed in the adjustment component 300, and the protrusion 230 of the temperature probe 200 can be selected to be snapped into one of the multiple slots 320, so that the fixed height of the temperature probe 200 can be adjusted, further enhancing the height adjustability of the temperature probe 200, and making it easy to adapt to the different heights of the stove base, base, pot support and other devices, increasing the versatility of the temperature probe assembly.
[0087] Of course, the adjustment part 300 can be easily opened by means of a snap-fit, so that the protrusion 230 of the temperature sensor 200 can be installed in different slots 320.
[0088] Furthermore, the base 400 is connected above the drive part 600, the adjusting member 300 is disposed above the base 400, and the adjusting member 300 is provided with a connecting hole 330 extending in the vertical direction. The base 400 is provided with a mating hole (not shown in the figure) corresponding to the position of the connecting hole 330. The connecting hole 330 and the mating hole are connected by threads.
[0089] By providing a connecting hole 330 extending in the vertical direction in the adjusting component 300, the adjusting component 300 and the base 400 can be connected and fixed in the vertical direction. When the temperature probe 200 needs to be repaired or replaced, the adjusting component 300 and the temperature probe 200 can be removed from the base 400 and replaced simply by unscrewing the screws or bolts fixing the adjusting component 300 from the secondary air inlet 110 in the middle of the flame cap 100, thus reducing the difficulty of disassembly and assembly.
[0090] In this embodiment, the first detection component 710 is a gravity sensor, which is disposed inside the base 400. The presence or absence of the temperature probe 200 in contact with the cookware is determined by detecting the gravity value of the temperature probe 200. The base 400 is located below the temperature probe 200, providing a mounting base for the gravity sensor and allowing for the detection of the gravity value of the temperature probe 200 at a suitable location. In other optional embodiments, the first detection component 710 may also be a pressure sensor.
[0091] In addition, the second detection component 730, the timing component 720, and the controller 700 can be independent components installed in the cooktop, or they can be functional modules integrated into the cooktop circuit board. Any existing second detection component 730, timing component 720, controller 700, or integrated circuit board with the above-mentioned functions is applicable to this embodiment.

Those skilled in the art can make various changes or modifications to these embodiments without departing from the principles and essence of this utility model, but all such changes and modifications fall within the scope of protection of this utility model.
