[0047] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts shall fall within the scope of protection of the present invention.

[0048] It should be noted that if the embodiments of the present invention involve directional indications (such as up, down, left, right, front, back, etc.), the directional indications are only used to explain the relative position relationship, movement status, etc. between the components in a certain specific posture. If the specific posture changes, the directional indications will also change accordingly.

[0049] In addition, if there are descriptions involving "first", "second", etc. in the embodiments of the present invention, the descriptions of "first", "second", etc. are only for descriptive purposes and cannot be understood as indicating or implying their relative importance or implicitly indicating the number of the indicated technical features. Therefore, the features limited to "first" and "second" may explicitly or implicitly include at least one of such features. In addition, if "and / or" or "and / or" appears in the full text, its meaning includes three parallel schemes. Taking "A and / or B" as an example, it includes scheme A, or scheme B, or a scheme in which A and B are satisfied at the same time. In addition, the technical solutions between the various embodiments can be combined with each other, but it must be based on the ability of ordinary technicians in this field to implement. When the combination of technical solutions is mutually contradictory or cannot be implemented, it should be deemed that such a combination of technical solutions does not exist and is not within the scope of protection required by the present invention.

[0050] In small household appliances with cooking functions, the inner pot is often heated by a heating plate. When the inner pot is placed in place, the heating plate automatically starts heating to make the inner pot reach the preset temperature; and when the inner pot is removed, the heating plate immediately stops heating.

[0051] Furthermore, in order to ensure the taste of food, small household appliances are often provided with temperature sensors, which are used to detect the temperature of the inner pot, thereby performing precise temperature control to ensure that the inner pot can be at a preset temperature.

[0052] However, the existing temperature sensor can only detect the temperature of the inner container and cannot determine when to start heating or when to stop heating.

[0053] The main purpose of the present invention is to provide a temperature sensor 100 with a travel switch, which is intended to quickly respond to heating needs and detect temperature.

[0054] See also Figures 1 to 7 In one embodiment of the present utility model, the temperature sensor 100 with a travel switch includes a pressing shell 1, a bracket 2, a travel trigger baffle 3, a hardware plug-in circuit 4 and a detection module 5. The bracket 2 is movably connected to the pressing shell 1 and encloses a movable cavity 11. The bracket 2 is provided with an movable hole 21 connected to the movable cavity 11. The travel trigger baffle 3 is provided on the side of the bracket 2 facing away from the movable cavity 11, and the travel trigger baffle 3 is provided with a through hole 31, and the through hole 31 corresponds to the movable hole 21. The hardware plug-in circuit 4 is provided on the side of the travel trigger baffle 3 facing away from the bracket 2, and corresponds to the through hole 31. Detection module 5, one end of the detection module 5 is connected to the pressing shell 1, and the other end passes through the movable hole 21 and the through hole 31 in sequence. The detection module 5 is provided with a conducting ring 53. The detection module 5 is used to detect the temperature of the inner tank. Among them, pressing the pressing shell 1 drives the detection module 5 to move along the movable hole 21, so that the conductive ring 53 has a first position and a second position. In the first position, the conductive ring 53 is in contact with the hardware plug-in circuit 4 and is conductive; in the second position, the conductive ring 53 is separated from the hardware plug-in circuit 4 and is disconnected.

[0055] In this embodiment, when the inner pot of an appliance such as an electric rice cooker, a pressure cooker, or a health pot is placed on the pressing shell 1, the pressing shell 1 is pressed and moved, driving the detection module 5 to move, and then driving the conductive ring 53 to move relative to the hardware plug-in circuit 4 to form a first position and a second position. In the second position, the conductive ring 53 is disengaged from the hardware plug-in circuit 4 and disconnected. It is determined that the pressing shell 1 is under pressure at this time, that is, the inner pot is placed, and heating is performed. In the first position, the conductive ring 53 is in contact with the hardware plug-in circuit 4 to achieve electrical conduction. It is determined that the pressing shell 1 is not under pressure at this time, that is, the inner pot is not placed, and therefore heating is stopped. The travel trigger baffle 3 is provided on the side of the bottom plate facing away from the pressing shell 1, providing effective support and limiting effects, preventing the detection module 5 from shaking during operation, and ensuring that the conductive ring 53 can be re-adapted to the travel trigger baffle 3 and connected to the hardware plug-in circuit 4 after each movement.

[0056] In one embodiment, see Figure 2 and Figure 3 The bracket 2 is provided with a block 22 on one side facing the pressing housing 1. The pressing housing 1 is provided with a slot 12 corresponding to the block 22. The block 22 is engaged with the slot 12. When the pressing housing 1 is pressed, the pressing housing 1 moves along the extension direction of the block 22.

[0057] In this embodiment, the engaging block 22 engages with the engaging slot 12, thereby limiting the movement direction of the pressing housing 1, allowing the pressing housing 1 to move along the extending direction of the engaging block 22. Furthermore, since one end of the engaging block 22 engages with the engaging slot 12, the pressing housing 1 is prevented from moving and disengaging from the engaging block 22. The pressing housing 1 and the bracket 2 are movably connected by the engaging connection, facilitating the removal of the pressing housing 1.

[0058] Optionally, a guide rod may be provided on the bracket 2 , and the pressing shell 1 may be movably inserted into the guide rod. A limiting portion may be provided at one end of the guide rod away from the bracket 2 to limit the movement of the pressing shell 1 .

[0059] In one embodiment, see Figures 1 to 3 The temperature sensor 100 with a travel switch also includes a first elastic member 13, the two ends of which are elastically connected to the pressing shell 1 and the bracket 2 respectively, and are located in the active cavity 11. There are two card blocks 22, and the two card blocks 22 are relatively arranged on both sides of the first elastic member 13.

[0060] In this embodiment, a first elastic member 13 is further disposed between the pressing housing 1 and the bracket 2. When the pressing housing 1 is pressed, the first elastic member 13 compresses, storing elastic potential energy. When the pressure from the inner container or other external object is removed, the elastic potential energy is released, and the pressing housing 1 automatically returns to its original position following the first elastic member 13. The locking limit at the end of the clamping block 22 prevents the pressing housing 1 from being separated from the clamping block 22. Furthermore, the first elastic member 13 absorbs some of the pressure during the pressing process of the pressing housing 1, helping to reduce the impact on the detection module 5 and thereby extending its service life.

[0061] It can be understood that the blocks 22 are relatively arranged on both sides of the first elastic member 13, which can effectively prevent the pressing shell 1 from shaking or tilting during movement, thereby ensuring that the pressing shell 1 can move along the extension direction of the blocks 22 without lateral movement.

[0062] In one embodiment, see Figure 2 and Figure 3 A ring-shaped protrusion 23 is provided on the side of the bracket 2 facing the pressing shell 1 , one end of the first elastic member 13 is sleeved on the ring-shaped protrusion 23 , and the other end is inserted into the pressing shell 1 .

[0063] In this embodiment, the annular protrusion 23 provides a fixed mounting position for the first elastic member 13, allowing one end of the first elastic member 13 to be quickly mounted on the bracket 2. The annular protrusion 23 also prevents one end of the first elastic member 13 from shifting during compression. The other end of the first elastic member 13 is inserted into the pressing housing 1, where the sidewalls of the pressing housing 1 restrain the other end of the first elastic member 13, preventing it from shifting. This ensures that the two ends of the first elastic member 13 do not shift during compression or extension, improving stability.

[0064] It is understandable that in the initial state, i.e., when no inner liner is placed, the first elastic member 13 is also in a compressed state. The first elastic member 13 holds the pressing shell 1 against one end of the clamping block 22 to prevent the pressing shell 1 from shaking. Of course, in the initial state, it is also possible for the first elastic member 13 to be in a natural state, neither stretched nor compressed. In this case, the pressing shell 1 may shake slightly. In addition, it should be noted that in this embodiment, the first elastic member 13 can be made of an elastic material such as a spring, a spring, or rubber. The elastic members described later can also be made of the same material and will not be described in detail.

[0065] In one embodiment, see Figure 1 and Figure 3 The detection module 5 includes a travel rod 52, a temperature detection component 51 and a second elastic member 54. One end of the travel rod 52 passes through the movable hole 21 and extends into the movable cavity 11, abutting against the pressing shell 1. The conductive ring 53 is sleeved on the travel rod 52, and the travel rod 52 forms a accommodating cavity 521. The temperature detection component 51 is arranged in the accommodating cavity 521 for detecting the temperature of the inner tank. The second elastic member 54 is sleeved on the travel rod 52 and is located on the side of the conductive ring 53 facing away from the travel trigger baffle 3. The two ends of the second elastic member 54 are elastically connected to the conductive ring 53 and the travel rod 52 respectively. Among them, the movement of the travel rod 52 drives the conductive ring 53 to move to form the first position and the second position.

[0066] In this embodiment, one end of the travel rod 52 passes through the movable hole 21 on the bracket 2 and extends into the movable cavity 11, abutting against the pressing shell 1, so that the pressing shell 1 can drive the travel rod 52 to move, and then drive the conductive ring 53 located on the travel rod 52 to move. The second elastic member 54 is mounted on the travel rod 52 and is located on the side of the conductive ring 53 facing away from the travel trigger baffle 3. The two ends of the second elastic member 54 are elastically connected to the conductive ring 53 and the travel rod 52 respectively. When the pressing shell 1 is pressed, the second elastic member 54 is compressed, and the conductive ring 53 moves from the first position to the second position. After the pressing shell 1 is released, the second elastic member 54 pushes the conductive ring 53 to return from the second position to the first position. In this way, the second elastic member 54 not only provides a reset function, but also can buffer the impact force during pressing, thereby improving the service life. The temperature detection component 51 is disposed in the accommodating cavity 521 of the stroke rod 52 , and the temperature detection component 51 is pressed against the pressing shell 1 , and the temperature of the inner pot is transferred to the temperature detection component 51 by pressing the shell 1 , thereby detecting the temperature of the inner pot.

[0067] It can be understood that in the initial state, the second elastic member 54 is in a compressed state and has elastic potential energy. The second elastic member 54 holds the conducting ring 53 against the bracket 2. The conducting ring 53 is in the first position and is connected to the hardware plug circuit 4.

[0068] In one embodiment, see Figure 3 and Figure 5 A first mounting groove 522 is formed on the side of the travel rod 52 facing away from the pressing housing 1 , and a sealing ring 523 is provided in the first mounting groove 522 . Both ends of the second elastic member 54 are elastically connected to the conducting ring 53 and the sealing ring 523 , respectively.

[0069] In this embodiment, in order to facilitate the installation of the second elastic member 54, a first installation groove 522 is formed on the travel rod 52, and a sealing ring 523 is provided in the first installation groove 522. One end of the second elastic member 54 is against the sealing ring 523, thereby providing support for one end of the second elastic member 54.

[0070] Optionally, a protrusion may be directly formed on the second elastic member 54 , and one end of the second elastic member 54 abuts against the protrusion, thereby providing support for the one end of the second elastic member 54 .

[0071] In one embodiment, see Figure 3 and Figure 5The travel rod 52 includes a first rod 524 and a second rod 525 connected to each other. One end of the first rod 524 is connected to the pressing housing 1. The conducting ring 53 is sleeved on the second rod 525. The inner diameter of the conducting ring 53 is larger than the outer diameter of the second rod 525, and the inner diameter of the conducting ring 53 is smaller than the outer diameter of the first rod 524. The movement of the second rod 525 drives the conducting ring 53 to move, thereby forming the first position and the second position.

[0072] In this embodiment, in the initial state, that is, when no inner pot is placed, the conductive ring 53 is sleeved on the outer side of the second rod 525. When the inner pot is placed, the first rod 524 and the second rod 525 move relative to the conductive ring 53. Since the inner diameter of the conductive ring 53 is larger than the outer diameter of the second rod 525, and the inner diameter of the conductive ring 53 is smaller than the outer diameter of the first rod 524, the second rod 525 will pass through the conductive ring 53 until the conductive ring 53 abuts the end surface of the first rod 524. At this time, the first rod 524 begins to push the conductive ring 53 to move, thereby disconnecting the conductive ring 53 from the hardware plug circuit 4. The conductive ring 53 changes from the first position to the second position. The external control system determines that the inner pot is now placed on the heating plate and starts heating. It should be noted that in this embodiment, only after the travel rod 52 moves a certain distance relative to the conductive ring 53 will the first rod 524 push the conductive ring 53 to move, thereby changing the connection state between the conductive ring 53 and the hardware plug circuit 4. This prevents accidental contact with the pressing shell 1 and misjudgment. The position of the conductive ring 53 can only be changed after sufficient pressure is applied to the pressing shell 1. When the inner pot is removed, the first rod 524 and the second rod 525 return to their original positions, driving the conductive ring 53 from the second position to the first position. The conductive ring 53 contacts and connects to the hardware plug circuit 4. The external control system determines that the inner pot has left the heating plate and stops heating.

[0073] Optionally, in the initial state, the conducting ring 53 may just abut against the end surface of the first rod 524 . At this time, as long as the housing 1 is pressed under pressure, the position of the conducting ring 53 will change, thereby improving the sensitivity of detection.

[0074] In one embodiment, see Figure 3 The detection module 5 also includes an insulating column 55, which is arranged in the accommodating cavity 521, and one end of the insulating column 55 is connected to the pressing shell 1. The insulating column 55 forms an isolation cavity 551, and the temperature detection component 51 passes through the isolation cavity 551 and abuts against the pressing shell 1.

[0075] In this embodiment, an insulating column 55 is further provided in the accommodating cavity 521 for isolating the temperature detection component 51 from other parts to prevent temperature or electrical interference and ensure the accuracy of the detection data.

[0076] Optionally, see Figure 4 The insulating column 55 and the pressing shell 1 are welded together by a metal welding piece 56 .

[0077] In one embodiment, see Figure 3 and Figure 4 The temperature detection assembly 51 includes a thermistor 511, an insulating spacer 512, and a wiring harness 513. The thermistor 511 is located in the accommodating cavity 521 and connected to the pressing housing 1. The insulating spacer 512 is provided on the thermistor 511 to isolate it from other electrical interference. The wiring harness 513 is connected to the thermistor 511.

[0078] In this embodiment, temperature detection assembly 51 includes a thermistor 511, an insulating separator 512, and a wiring harness 513. Thermistor 511 is used to detect temperature changes and generate corresponding resistance changes. One end of the wiring harness 513 is connected to thermistor 511, and the other end is connected to an external detection circuit. The insulating separator 512 prevents other circuits from generating electrical interference with thermistor 511, ensuring that the temperature detection signal is not affected by other components, thereby improving data accuracy.

[0079] In one embodiment, see Figure 3 、 Figure 6 and Figure 7 A second mounting slot 32 is formed on the side of the travel trigger baffle 3 facing away from the active chamber 11. The hardware insert circuit 4 is mounted within this second mounting slot 32 and includes a contact portion 41 and a connector 42. The contact portion 41 is positioned within the second mounting slot 32 and surrounds the through-hole 31. The conductive ring 53 moves to connect and disconnect the conductive ring 53 from the contact portion 41. The connector 42 is connected to the contact portion 41, with at least a portion of the connector 42 protruding from the second mounting slot 32 to form a connector end 421, which is connected to the control system.

[0080] In this embodiment, a second mounting slot 32 is provided on the side of the travel trigger baffle 3 facing away from the active chamber 11, and the hardware plug-in circuit 4 is mounted within this second mounting slot 32. The hardware plug-in circuit 4 comprises a contact portion 41 and a connecting portion 42. The contact portion 41 is disposed within the second mounting slot 32, surrounding the through-hole 31. The inner diameter of the circular ring formed by the contact portion 41 is smaller than the outer diameter of the conductive ring 53. This allows the conductive ring 53 to contact or disconnect with the contact portion 41 when the first rod 524 moves the conductive ring 53 relative to the hardware plug-in circuit 4. This allows the conductive ring 53 to contact or disconnect with the contact portion 41, thereby determining whether an inner container is placed and whether heating can be initiated or deactivated. A portion of the connecting portion 42 protrudes from the second mounting slot 32 and forms a contact end. The control system connects to the hardware plug-in circuit 4 via the contact end. The control system determines whether heating is required based on the corresponding connect or disconnect signals.

[0081] The present invention's technical solution detects the temperature of the inner pot through detection module 5. Pressing the outer shell 1, upon receiving pressure from the inner pot, moves detection module 5, disconnecting conductive ring 53 from hardware plug-in circuit 4, thereby immediately starting heating. When the inner pot is removed, conductive ring 53 connects to hardware plug-in circuit 4, immediately stopping heating. This allows for both temperature detection of the inner pot and instantaneous heating, enabling better control of food texture through multi-stage heating.

[0082] The temperature sensor 100 with a travel switch includes a push-on housing 1, a bracket 2, a travel trigger baffle 3, a hardware plug-in circuit 4, and a detection module 5. The push-on housing 1 is movably connected to the bracket 2 and forms a retractable movable cavity 11 with the first elastic member 13. To achieve more accurate temperature measurement, a metal welding piece 56 is inserted into the front end of the insulating column 55 to weld the travel rod 52 and the push-on housing 1 into an integral structure. An insulating separation sleeve 512 and a thermistor 513 are provided in the isolation cavity 551 of the insulating column 55. A travel rod 52 is provided on the outside of the insulating column 55. The upward and downward movement of the push-on housing 1 drives the travel rod 52 to move up and down, and a travel trigger baffle 3 is provided on the bracket 2. The travel rod 52 is configured as two cylinders of different diameters, namely a first rod body 524 and a second rod body 525. When the travel rod 52 passes through the travel trigger baffle 3 and moves downward, it drives the conductive ring 53 to disconnect the hardware plug circuit 4. When the travel rod 52 moves upward, it pulls the conductive ring 53 to close the hardware plug circuit 4. The signal simulating the conduction of the hardware plug circuit 4 is converted into a control signal to control the heating and stopping switch, thereby better controlling the taste of food through multi-stage heating. The second elastic member 54 assists in the installation of the conductive ring 53 to improve the reliability and effectiveness of the conductive signal.
