[0014] Furthermore, the ignition knob that displays the temperature also includes:

[0015] A temperature display screen is connected to the circuit board, with the interface side of the temperature display screen facing the fixing member;

[0016] A knob housing, one end of which is connected to the knob guide plate, and the other end of which is connected to the display side of the temperature display screen.

[0017] Furthermore, the fixing fastener includes:

[0018] A retaining ring is inserted into the connector, and the outer ring of the retaining ring is connected to the inner wall of the connector.

[0019] Multiple fixing parts are arranged around the fixing ring as the center and are all connected to the fixing ring. Each fixing part is provided with a flange, and each flange is rotatably connected to the bottom end of the connector.

[0020] Furthermore, the outer wall of the bottom end of the connector is provided with a rotating annular groove, which engages with the flange so that the rotating annular groove can move relative to the flange.

Depending on the context, the words "if" or "when" as used herein may be interpreted as "in the event of," "when," or "in response to a determination."

[0037] In the description of this utility model, it should be noted that, unless otherwise explicitly defined, terms such as "setting," "installation," and "connection" should be interpreted broadly, and those skilled in the art can reasonably determine the specific meaning of the above terms in this utility model in conjunction with the specific content of the technical solution.

[0038] As described in the background art, in the prior art, the current temperature detection and display structure is relatively complex to install and occupies a certain amount of space. In addition, the position of the temperature measuring device in this structure is prone to displacement and the structure is prone to water seepage, which can lead to temperature display errors and thus affect the cooking effect.

[0039] Reference Figures 1 to 3 In some embodiments of this utility model, an ignition knob for displaying temperature includes: a temperature measuring device 100, a base 200, a knob guide plate 300, a temperature measuring fixing plate 400, a waterproof ring 401, a temperature display screen 700, and a knob housing 800.

[0040] With the temperature measuring device 100 at the top, the base 200, knob guide plate 300, temperature measuring fixing plate 400, waterproof ring 401 and temperature display screen 700 are arranged sequentially from top to bottom.

[0041] The temperature measuring device 100 is located on one side of the base 200, while the knob guide plate 300, temperature measuring fixing plate 400, waterproof ring 401, temperature display screen 700 and knob housing 800 are all located on the other side of the base 200.

[0042] The knob guide plate 300 is fitted inside the base 200. One end of the knob housing 800 is connected to the knob guide plate 300, and the other end of the knob housing 800 is connected to the display side of the temperature display screen 700 to form an installation space. The display side of the temperature display screen 700 faces outward so that the user can view the current temperature.

[0043] In other words, one end of the knob housing 800 is connected to the base 200 via the knob guide plate 300, and the other end of the knob housing 800 is connected to the display side of the temperature display screen 700. Through the knob housing 800, the temperature display screen 700, and the knob guide plate 300, an installation space is formed on the base 200, and the temperature measuring fixing plate 400 and the waterproof ring 401 are both set in this installation space.

[0044] The knob guide plate 300 is provided with a connector 310 and an annular guide 320 that are connected to each other. The connector 310 is located in the center of the knob guide plate 300 and extends towards the temperature measuring fixing plate 400. The annular guide 320 is arranged around the connector 310 with the connector 310 as the center. The top of the connector 310 is flush with the annular guide 320 and is on the same horizontal plane.

[0045] In other words, the connector 310 and the annular guide 320 are set on the same plate, with the connector 310 located at the center of the plate. The annular guide 320 is arranged around the connector 310 as the center, so that the knob guide plate 300 can rotate.

[0046] The connector 310 is a connecting tube. The geometry of the annular guide 320 can be semi-annular or fully annular, so that the knob guide plate 300 is not blocked by the fixing post 420 on the temperature measuring fixing plate 400 when rotating. In this embodiment, no specific limitation is made on the geometry of the annular guide 320.

[0047] The base 200 is provided with a fixing port 210, which is opposite to and connected to the annular guide port 320.

[0048] The temperature measuring mounting plate 400 is provided with a fixing fastener 410 and a fixing post 420 that are connected to each other. The fixing fastener 410 is located in the center of the temperature measuring mounting plate 400 and is rotatably connected to the connector 310 so that the knob guide plate 300 can rotate relative to the temperature measuring mounting plate 400. The fixing post 420 is located on one side of the fixing fastener 410 and can pass through the annular guide port 320 and the fixing port 210 in sequence to connect with the temperature measuring device 100. The fixing post 420 is used to fix the temperature measuring device 100.

[0049] In other words, with the annular guide 320 as a stationary reference object, the fixed column 420 moves along the annular track of the annular guide 320, and correspondingly, the fixed fastener 410 rotates relative to the connector 310.

[0050] The waterproof ring 401 is fitted onto the temperature measuring fixing plate 400, and the waterproof ring 401 is fitted onto the outer wall of the temperature measuring fixing plate 400 to prevent external water seepage.

[0051] In one embodiment, the knob housing 800 rotates, causing the knob guide plate 300 to rotate. Through the fixing fastener 410 and the connector 310, the knob guide plate 300 rotates relative to the temperature measuring fixing plate 400, causing the annular guide port 320 to be displaced. The annular guide port 320 can move relative to the fixing post 420. The fixing fastener 410 and the fixing post 420 on the temperature measuring fixing plate 400 do not move, and the position of the temperature measuring device 100 does not shift, thereby improving the stability of the installation of the temperature measuring device 100. Furthermore, the rotational connection between the knob guide plate 300 and the temperature measuring fixing plate 400 enhances the convenience of installing the temperature detection and display structure.

[0052] Through the above scheme, the annular guide 320 provided on the knob guide plate 300 allows the fixing post 420 on the temperature measuring fixing plate 400 to pass through the annular guide 320 and the fixing port 210 on the base 200 to fix the temperature measuring device 100 located on one side of the base 200. The connecting piece 310 of the rotating guide plate is rotatably connected to the fixing fastener 410 of the temperature measuring fixing plate 400, saving installation space. When the knob is rotated, that is, when the knob guide plate 300 is rotated, the rotating guide plate can rotate relative to the temperature measuring fixing plate 400, and the fixing post 420 passing through the annular guide 320 is not affected. The fixing post 420 does not rotate, and the temperature measuring device 100 does not rotate with it. The waterproof ring 401 is fitted onto the temperature measuring fixing plate 400 to prevent external water leakage. Compared with the prior art, this application minimizes the possibility of temperature measuring device 100 offset and external water leakage, avoids temperature display errors, improves the stability and convenience of temperature detection and display structure installation, and improves the accuracy of temperature detection.

[0053] Reference Figures 1 to 3 In some embodiments of this utility model, an ignition knob for displaying temperature includes: an ignition switch shaft 900, a circuit board 500, and a fixing member 600.

[0054] The base 200 has a through hole 220 in the center, which is connected to the connector 310. The temperature measuring device 100 is located on one side of the ignition switch shaft 900. The ignition switch shaft 900 passes through the through hole 220 and is inserted into the connector 310 of the knob guide plate 300 in the direction of the temperature measuring fixing plate 400. The tail end of the temperature measuring device 100 is inserted into the fixing ring 411 of the fixing fastener 410 of the temperature measuring fixing plate 400.

[0055] In one embodiment, the knob housing 800 selects, causing the knob guide plate 300 to rotate, the connector 310 to rotate, and the connected ignition switch shaft 900 to move, thereby achieving ignition.

[0056] The circuit board 500 is electrically connected to the temperature measuring device 100 and the temperature display screen 700 respectively, and the circuit board 500 is located between the temperature measuring fixing plate 400 and the fixing member 600.

[0057] One side of the fastener 600 faces the circuit board 500, and the other side of the fastener 600 faces the interface side of the temperature display screen 700. The fastener 600 is used to fix the circuit board 500. Through the circuit board 500, the fastener 600 is tightly connected to the temperature measuring fixing plate 400, so that one side of the fastener 600 can be tightly connected to the waterproof ring 401.

[0058] In one embodiment, the temperature measuring fixing plate 400 and the circuit board 500 are both provided with corresponding screw holes, and the fixing member 600 is provided with corresponding screw slots, so that screws can be passed through the corresponding screw holes and inserted into the corresponding screw slots in sequence, thereby passing through the temperature measuring fixing plate 400 and the circuit board 500 in sequence and being inserted into the fixing member 600, thereby fixing the circuit board 500 between the temperature measuring fixing plate 400 and the fixing member 600.

[0059] The fastener 600 can be a fixing cover or a fixing base. In this embodiment, no specific restrictions are made on the geometry of the fastener 600.

[0060] In other words, the circuit board 500 and the fixing component 600 are both located within the installation space formed by the knob housing 800, the temperature display screen 700, and the knob guide plate 300. With the temperature measuring device 100 at the top, the circuit board 500 is located below the temperature measuring fixing plate 400, and the fixing component 600 is located below the circuit board 500. The base 200, the knob guide plate 300, the temperature measuring fixing plate 400, the waterproof ring 401, the circuit board 500, the fixing component 600, and the temperature display screen 700 are arranged sequentially from top to bottom.

[0061] Reference Figures 1 to 3 In some embodiments of this utility model, the fixing fastener 410 includes a fixing ring 411 and a plurality of fixing parts 412.

[0062] The retaining ring 411 is inserted into the connector 310, and the connector 310 is sleeved on the retaining ring 411. The outer ring of the retaining ring 411 is in contact with the inner wall of the connector 310. The retaining ring 411 and the connector 310 are on the same vertical plane.

[0063] Multiple fixing parts 412 are connected to a fixing ring 411. Both the fixing ring 411 and the multiple fixing parts 412 are disposed on the temperature measuring fixing plate 400, located in the central area of ​​the temperature measuring fixing plate 400. With the fixing ring 411 as the center, the multiple fixing parts 412 are arranged around the temperature measuring fixing plate 400.

[0064] Each fixing part 412 has a flange 413 at its top end. Each flange 413 is rotatably connected to the bottom end of the connector 310. The flange 413 can slide onto the bottom end of the connector 310 so that when the knob guide plate 300 is rotated, the connector 310 can rotate relative to each flange 413.

[0065] The flange 413 can be arc-shaped to allow the connector 310 to rotate, or it can be other shapes to allow rotation. In this embodiment, the geometry of the flange 413 is not restricted.

[0066] Reference Figures 1 to 3 In some embodiments of this utility model, the outer wall of the bottom end of the connector 310 is provided with a rotating annular groove 311, and each flange 413 in the fastener 410 is embedded in the rotating annular groove 311.

[0067] When the knob guide plate 300 rotates, it drives the connector 310 to rotate, so that the rotating annular groove 311 can move relative to each flange 413, thereby not driving the temperature measuring fixing plate 400 to move and avoiding the offset of the temperature measuring device 100.

[0068] In one embodiment, the knob guide plate 300 is provided with a support member 330 and a snap-fit ​​member 340.

[0069] The support member 330 extends toward the temperature measuring fixing plate 400. One end of the support member 330 is connected to the knob guide plate 300, and the other end of the support member 330 abuts against the temperature display screen 700.

[0070] The snap-fit ​​component 340 extends toward the temperature measuring fixing plate 400. One end of the snap-fit ​​component 340 is connected to the knob guide plate 300, and the other end of the snap-fit ​​component 340 is snapped into the inner wall of the knob housing 800 so that the knob housing 800 can drive the knob guide plate 300 to rotate.

[0071] In one embodiment, the support member 330 and the snap-fit ​​member 340 are arranged alternately around the connecting pipe, with the support member 330 and the snap-fit ​​member 340 on the same circumference. The support member 330 and the snap-fit ​​member 340 are located on the outer edge of the knob guide plate 300, and the distance from the support member 330 and the snap-fit ​​member 340 to the connecting member 310 is greater than the distance from the annular guide opening 320 to the connecting member 310. The support member 330 and the snap-fit ​​member 340 can also be arranged on the knob guide plate 300 in other array arrangements, which are not limited in this embodiment.

[0072] The buckle 340 has a raised part that engages with the inner wall of the knob housing 800 to connect the knob housing 800 and the knob guide plate 300.

[0073] Reference Figure 1 and Figure 4In some embodiments of this utility model, the circuit board 500 is provided with an amplifier circuit 510, a control circuit 520 and a cold junction compensation circuit 530.

[0074] The input terminal of the amplifier circuit 510 is electrically connected to the temperature measuring device 100, and the output terminal of the amplifier circuit 510 is electrically connected to the input terminal of the control circuit 520. The amplifier circuit 510 is used to amplify the temperature value detected by the temperature measuring device 100.

[0075] The output terminal of the cold end compensation circuit 530 is electrically connected to the input terminal of the control circuit 520. The cold end compensation circuit 530 is used to detect the temperature of the cold end of the stove and obtain the cold end temperature value for temperature compensation.

[0076] The output of the control circuit 520 is electrically connected to the temperature display screen 700. The control circuit 520 receives the temperature value and the cold junction temperature value, performs temperature compensation based on the cold junction temperature value, and determines the current temperature to be displayed. The temperature display screen 700 displays the current temperature.

[0077] Among them, the temperature measuring device 100 is a thermocouple temperature detector.

[0079] By using an ignition knob that displays the temperature, external water seepage and temperature sensor misalignment are reduced, improving temperature measurement accuracy and enhancing the user's cooking experience.
