[0002] Most electric kettles, health-preserving kettles, and tea machine kettles on the market that have temperature detection are connected to the main control circuit through a 5-pin coupler. This 5-pin connection can only heat and detect the temperature inside the kettle.

[0003] With product upgrades, there is a need to monitor the water temperature inside the kettle, as well as to sense information such as the water level, to meet diverse customer needs. The traditional approach is to replace the 5-pin connector with a 6- or 7-pin connector to add a subsystem inside the kettle to detect water temperature and water level. However, since the 5-pin connector currently has a large market capacity and is relatively inexpensive, using a 6- or 7-pin connector would increase equipment costs. Utility Model Content

[0037] Figure 3This is a schematic diagram of one embodiment of the detection device provided in this application. Detailed Implementation

[0038] The technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only a part of the embodiments of this application, and not all of the embodiments. Based on the embodiments of this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application. At the same time, in the description of the embodiments of this application, the terms "first," "second," etc., are only used to distinguish descriptions and should not be construed as indicating or implying relative importance. Thus, features defined with "first" and "second" may explicitly or implicitly include one or more features. In the description of the embodiments of this application, "multiple" means two or more, unless otherwise explicitly specified.

[0039] In one embodiment of this application, the detection device can be installed in a kettle. Please refer to [link / reference]. Figure 1 To better understand the detection device provided in the embodiments of this application, the application environment applicable to the embodiments of this application will be described below.

[0040] Please see Figure 1 , Figure 1 This diagram illustrates an application environment of the detection device provided in one embodiment of this application. As one implementation, the detection device provided in this embodiment is applied to a kettle. The kettle can be, for example,... Figure 1 The electric kettle 100 shown can be connected to a terminal device 200 via a network. The network serves as a medium for providing a communication link between the electric kettle 100 and the terminal device 200. The network can include various connection types, such as wired communication links, wireless communication links, etc., and this embodiment does not limit this. Optionally, in other embodiments, the electric kettle can also be a health-preserving kettle or a tea-drinking machine kettle, etc., equipped with temperature detection.

[0041] It should be understood that Figure 1 The electric kettle 100, network and terminal equipment 200 in the figure are merely illustrative. If the kettle 100 does not have network communication function, it will not affect the implementation of the technical solution of this application.

[0042] Please see Figure 2 , Figure 2 This illustration shows a schematic diagram of a detection device according to an embodiment of the present application. The implementation principle of a kettle in the related art is as follows: Figure 2As shown, the detection device is applied to a kettle, and the detection device includes: a main control circuit; and a kettle-end circuit; P1 in the main control circuit is a 5-pin power supply base for products such as kettles, health pots, and tea machines, and P10 in the kettle-end circuit is a 5-pin coupler inside the kettle. Specifically,

[0043] One end of interface P1-1 in the 5-pin power supply base is connected to ground, and the other end of interface P1-1 in the 5-pin power supply base is connected to P10-1 of the 5-pin coupler in the kettle end to ensure circuit safety.

[0044] One end of interface P1-2 in the 5-pin power supply base is connected to the neutral wire, and the other end of interface P1-2 in the 5-pin power supply base is connected to P10-2 of the 5-pin coupler in the kettle end, which is used to connect to one pole of the power supply of the heating plate in the kettle end to heat the water in the kettle.

[0045] One end of interface P1-3 in the 5-pin power supply base is connected to a relay switch, and the other end of interface P1-3 in the 5-pin power supply base is connected to P10-3 of the 5-pin coupler in the kettle end, which is used as the other pole for power supply to the heating plate in the kettle end, so as to heat the water in the kettle.

[0046] One end of interface P1-4 in the 5-pin power supply base is connected to MCU1 through the detection circuit, and the other end of interface P1-4 in the 5-pin power supply base is connected to P10-4 of the 5-pin coupler in the kettle end for temperature detection, which is used to collect the temperature information of the water in the kettle.

[0047] One end of interface P1-5 in the 5-pin power supply base is connected to the low-voltage GND network, and the other end of interface P1-5 in the 5-pin power supply base is connected to P10-5 of the 5-pin coupler in the kettle end for temperature detection, which is used to feed back the collected temperature information to the main control circuit.

[0048] In related technologies, the 5-pin coupler in the kettle-side circuit is connected to the main control circuit. One pin is used to connect to ground, two pins are used to connect to the heating element, and the other two pins are used to connect to the temperature sensor. Figure 2 The heating device shown is a heating plate. Different types of heating devices can be selected according to different products, such as heating rods. Figure 2 The 5-pin connector shown can only heat and detect the temperature inside the kettle. If other information needs to be monitored, it cannot be implemented. Therefore, the approach in related technologies is to replace the 5-pin connector with a 6-pin or 7-pin connector to add a subsystem inside the kettle to detect information such as water temperature and water level. If a 6-pin or 7-pin connector is used, the cost of improving the kettle increases. For example, the hardware cost of the kettle increases by 50%. Furthermore, according to the current logic, each time new detection information is added, a different connector needs to be added, making it difficult to upgrade the kettle.

[0049] Based on the above description of related technologies, the 5-pin connector currently has a large market capacity and is relatively inexpensive, but it cannot meet the diverse needs of users. For example, it cannot monitor the water temperature in the kettle while also sensing information such as the water level. Based on this, the embodiment of this application is proposed. In this embodiment, without changing the structure of the kettle body and base, the two pins originally used for single-channel temperature detection are used to realize the detection and transmission of information such as multi-channel temperature and multi-segment water level. The main control circuit determines whether it is in the power output stage or the data receiving stage. The kettle end circuit collects data according to the state of the main control circuit, and then feeds back the collected information to the main control circuit in a time-division manner according to the state, thereby realizing the detection of multiple types of parameters of the kettle.

[0050] Specifically, refer to Figure 3 A schematic diagram of the structure of one embodiment of the detection device provided in this application. Figure 3 The detection device is applied to a kettle, and the detection device includes:

[0051] Main control circuit; and,

[0052] Kettle terminal circuit;

[0053] The main control circuit includes: a first microcontroller chip and a 5-pin power supply base that are electrically connected; the first microcontroller chip is used to supply power to the kettle circuit through the 5-pin power supply base in the power supply state, or to receive at least two types of detection information sent through the 5-pin power supply base in the communication state.

[0054] In this embodiment, the main control circuit refers to the circuit that controls the heating of water in the kettle. The individual circuit components in the kettle-side circuit are not limited in this embodiment. The main control circuit is located in the control section of the kettle, for example, in the base of the kettle. The main control circuit includes a first microcontroller chip, such as... Figure 1 The MUC1 in the model also includes a 5-pin power supply base in its main control circuit, such as... Figure 1 In this embodiment, P1, which is electrically connected to the first microcontroller chip and the 5-pin power supply base, can switch states via the first microcontroller chip to supply power to the kettle or receive detection information sent by the kettle. This detection information includes water level information, temperature information, overflow information, or other kettle control-related information. Specifically:

[0055] In this embodiment, the first microcontroller chip switches states according to the time-division control signal MCU-IO. For example, the time-division control signal is a high-level signal and a low-level signal. Under the high-level signal, the main control circuit is in power supply state, and under the low-level signal, the main control circuit is in communication state. In this embodiment, the magnitude of the high-level signal and the low-level signal is not limited. For example, the high-level signal is 5V and the low-level signal is 0V. In this embodiment, the interval between the high and low levels can be set according to the specific scenario. For example, the time interval can be 5ms. In this embodiment, the duration of the high and low levels is determined based on the power ripple at the kettle end and the transmission duration. For example, if the power ripple at the kettle end is determined to be less than 200mV, the high-low level interval should not be greater than 5ms, and the transmission duration is 4ms, then the duration of the low level is 5ms and the duration of the high level is 4-5ms.

[0056] like Figure 1 As shown, the first microcontroller chip includes 1-16 interfaces. Interfaces 1 and 2 are used for power supply to the first microcontroller chip. Interface 6 connects to a relay switch to control the kettle's heating. Interface 8 (also called MCU-IO or input / output interface) is used for time-division multiplexing control signals for state control, i.e., switching between power supply and communication states. Interface 10 (also called MCU-RX or data transmission interface) is used to receive detection information sent by the kettle's circuit. It is understood that the number of interfaces in the first microcontroller chip in this embodiment, or the function of each interface, is not specifically limited.

[0057] In this embodiment, the first microcontroller chip in the main control circuit switches states via a time-division control signal. This allows for the detection of multiple types of information without the need to add a base chip interface, enabling the kettle to collect various types of detection information and achieve intelligent control without increasing costs.

[0058] The kettle-end circuit includes: a 5-pin coupler, a second microcontroller chip, and a power storage component connected electrically; the 5-pin coupler is connected to the 5-pin power supply base; when the main control circuit is in a power supply state, the power storage component is used to receive and store the power supply from the main control circuit; the second microcontroller chip is used to collect the at least two types of detection information; when the main control circuit is in a communication state, the power storage component is used to power the second microcontroller chip; and the second microcontroller chip is used to send the at least two types of detection information to the main control circuit through the power supply from the power storage component.

[0059] In this embodiment, the detection device further includes a kettle-end circuit, which includes a 5-core coupler, a second microcontroller chip, and a power storage component connected electrically. In this embodiment, the 5-core coupler is connected to a 5-core power supply base in the main control circuit. In this embodiment, the main control circuit has a 5-core power supply base, and the kettle-end circuit has a 5-core coupler. Without adding any additional core interfaces, it is possible to collect various types of detection information, thereby achieving kettle control. Specifically:

[0060] In this embodiment, the kettle-end circuit includes a power storage component. This component receives and stores power when the main control circuit is in a power-on state, and supplies power to the second microcontroller chip when the main control circuit is in a communication state (i.e., the main control circuit stops supplying power to the kettle-end circuit). The power in the power storage component can be a capacitor or other components. The power source for the power storage component is not limited in this embodiment. To enable long-term cyclic use of the power storage component, it is stated that the power in the power storage component is supplied by the main control circuit. However, in some cases, those skilled in the art can use a battery for power supply; that is, the method of using a battery is the same as the technical concept of this application.

[0061] In this embodiment, the second microcontroller chip can collect detection information based on the detected status of the main control circuit. When the main control circuit is in a power supply state, the second microcontroller chip can collect detection information and, when the main control circuit is in a communication state, use the power provided by the energy storage component to feed back the detection information to the main control circuit. The detection information includes temperature information, water level information, overflow information, etc. In this embodiment, the detection information is set according to the specific scenario.

[0062] The detection device in this embodiment is installed inside a kettle. The device comprises two parts: a main control circuit located in the kettle's base and used for state switching. In this embodiment, the kettle has two states: a power supply state and a communication state. In the power supply state, the main control circuit supplies power to the kettle, enabling the kettle-side circuit to collect detection information. In the communication state, the main control circuit receives detection information sent by the kettle-side circuit. The other part of the detection device is the kettle-side circuit, located in the kettle body, used to receive control operations from the main control circuit. When the main control circuit is in the power supply state, it collects detection information, such as detecting the water level, overflow, and water heating temperature. When the main control circuit is in the communication state, the kettle-side circuit uses a power storage component to send at least two types of detection information to the main control circuit, allowing the main control circuit to better control the kettle. In other words, this embodiment achieves multi-dimensional data detection while reducing costs by using time-division multiplexing of the detection device.

[0063] In one embodiment of this application, the main control circuit further includes: a switching component, which is disposed between the first microcontroller chip and the 5-core power supply base;

[0064] The switching component is used to receive a first control signal (e.g., a high-level signal) from the input / output interface of the first microcontroller chip, and switch to the power supply state to supply power to the kettle terminal circuit through the 5-pin power supply base; or, the switching component is also used to receive a second control signal (e.g., a low-level signal) from the input / output interface of the first microcontroller chip, switch to the communication state, and receive the at least two detection information through the data transmission interface of the first microcontroller chip.

[0065] In this embodiment, the main control circuit further includes a switching component. The switching component converts the control signal of the first microcontroller chip, enabling the kettle circuit to determine whether the main control circuit is in a power supply state or a communication state. In this embodiment, the switching component is disposed between the first microcontroller chip and the 5-pin power supply base. The switching component is used to receive a first control signal from the input / output interface of the first microcontroller chip and switch to the power supply state to supply power to the kettle circuit through the 5-pin power supply base; or, the switching component is also used to receive a second control signal from the input / output interface of the first microcontroller chip and switch to the communication state, and receive the at least two detection information through the data transmission interface of the first microcontroller chip.

[0066] In this embodiment, the switching component converts the control signal from the first microcontroller chip into status information, enabling the kettle circuit to respond accordingly. Since the control signal from the first microcontroller chip varies in this embodiment, the circuit components in the switching component are not limited.

[0067] Specifically, in this embodiment, the switching component further includes: a first resistor, a second resistor, a third resistor, and a transistor electrically connected; the input / output interface of the first microcontroller chip is connected to one end of the first resistor, the other end of the first resistor is connected to the base of the transistor, and is connected to the emitter of the transistor through the second resistor; the data transmission interface of the first microcontroller chip is connected to one end of the third resistor, the other end of the third resistor is connected to the 5-pin power supply base, and is connected to the base electrode of the transistor.

[0068] Reference Figure 3 The switching component of this application includes a first resistor R1, a second resistor R2, a third resistor R3, and a transistor Q1. The input / output interface of the first microcontroller chip is connected to one end of the first resistor, and the other end of the first resistor is connected to the base of the transistor and, through the second resistor, to the emitter of the transistor. The data transmission interface of the first microcontroller chip is connected to one end of the third resistor, and the other end of the third resistor is connected to the 5-pin power supply base and to the base electrode of the transistor. In this embodiment, the switching component determines whether the transistor is turned on or off based on the control signal from the first microcontroller chip, further determining the state of the first microcontroller chip. Specifically:

[0069] The switching component is used to receive a first control signal from the input / output interface of the first microcontroller chip, turn on the transistor, and form a first power supply consisting of the first resistor, the second resistor, and the transistor to supply power to the kettle terminal circuit; or,

[0070] The switching component is used to receive a second control signal from the input / output interface of the first microcontroller chip, determine that the transistor is not conducting, and receive at least two types of detection information through the third resistor and the data transmission interface of the first microcontroller chip.

[0071] In this embodiment, when the main control circuit is in a power supply state, when the first microcontroller chip MCU1 sends the first control information through the MCU_IO pin, Q1 is turned on to control the power supply circuit composed of R1 / R2 / Q1 to supply power to the second microcontroller chip. Alternatively, when the main control circuit is in a communication state, it receives the second control signal from the input / output interface of the first microcontroller chip, Q1 is not turned on, and at least two types of detection information are received through the third resistor and the data transmission interface of the first microcontroller chip. This achieves time-division multiplexing of power supply and communication, without the need for additional interfaces, and enables multi-type information detection of the kettle.

[0072] In one embodiment of this application, the kettle-end circuit further includes a voltage divider detection circuit, which is disposed between the 5-pin coupler and the second microcontroller chip; the voltage divider detection circuit includes at least two resistors, and is used to determine whether the main control circuit is in the power supply state or in the communication state based on the voltage division between the at least two resistors.

[0073] In this embodiment, the voltage divider detection circuit uses at least two resistors connected in series. The state of the main control circuit is determined based on the voltage division between these two resistors. Specifically,

[0074] The voltage divider detection circuit includes: a fourth resistor, a fifth resistor, and a sixth resistor;

[0075] One interface of the 5-pin coupler is connected to one end of the fourth resistor, one end of the fifth resistor, and the energy storage component; the other end of the fourth resistor is connected to the first interface of the second microcontroller chip; the second microcontroller chip is powered through the first interface of the second microcontroller chip.

[0076] Reference Figure 3 In this embodiment, the voltage divider detection circuit includes a fourth resistor R10, a fifth resistor R11, and a sixth resistor R12. One interface P10-4 of the 5-pin coupler is connected to one end of the fourth resistor R10, one end of the fifth resistor R11, and the energy storage component, respectively. The other end of the fourth resistor R10 is connected to the first interface MCU10-TX of the second microcontroller chip. The second microcontroller chip is powered through the first interface of the second microcontroller chip.

[0077] The other end of the fifth resistor is connected to one end of the sixth resistor and the second interface of the second microcontroller chip; the other end of the sixth resistor is grounded; the second interface of the second microcontroller chip is connected to a sensor for collecting the at least two types of detection information.

[0078] Reference Figure 3In this embodiment of the voltage divider detection circuit, the other end of the fifth resistor R11 is connected to one end of the sixth resistor R12 and the second interface MCU10-PC of the second microcontroller chip; the other end of the sixth resistor R12 is grounded; the second interface MCU10-PC of the second microcontroller chip is connected to a sensor for collecting the at least two types of detection information. In this embodiment of the application, the type and number of sensors are not limited. For example, the sensors include temperature detection sensor 1, temperature detection sensor 2, water level detection sensor 1, water level detection sensor 2, water level detection sensor 3, overflow detection sensor, etc. In this embodiment of the application, the user can flexibly set different types and numbers of sensors for detection according to the state of the kettle, so that the information of the kettle is more comprehensive.

[0079] Furthermore, in one embodiment of this application, the voltage divider detection circuit determines the state of the main control circuit based on the separation between the fifth resistor and the sixth resistor connected in series, specifically:

[0080] If the voltage divider detection circuit detects that the voltage division between the fifth resistor and the sixth resistor meets the first condition, it determines that the main control circuit is in the power supply state; or,

[0081] If the voltage divider detection circuit detects that the voltage division between the fifth resistor and the sixth resistor does not meet the first condition, it determines that the main control circuit is in the communication state.

[0082] The voltage divider detection circuit detects the voltage division between the fifth resistor R11 and the sixth resistor R12. The magnitude of the voltage division is determined based on the values ​​of the fifth resistor R11 and the sixth resistor R12, as well as the power supply of the first microcontroller chip, to establish a first condition. For example, the first condition is 10:1. If the voltage divider detection circuit detects that the voltage division between the fifth resistor R11 and the sixth resistor R12 meets the first condition, the main control circuit is determined to be in the power supply state; or, if the voltage divider detection circuit detects that the voltage division between the fifth resistor R11 and the sixth resistor R12 does not meet the first condition, the main control circuit is determined to be in the communication state. In this embodiment, the state of the main control circuit is determined based on the voltage division detected by the voltage divider detection circuit. When the detection end confirms that the main control end is in the data receiving state, the detection end MCU10 sends information to the main control end MCU_RX port through the MCU10_TX pin and resistor R10. The main control end MCU1 receives the data and completes the closed-loop detection.

[0083] Furthermore, in one embodiment of this application, the energy storage component includes a diode, at least two capacitors, and a control module;
