[0041] In existing technology, handheld coffee machines are typically equipped with a built-in heating system to ensure a rapid supply of hot water for brewing coffee. This heating method generally uses electric heating elements, such as heating plates or heating tubes, which can quickly heat water to the desired temperature. To ensure that the heating element can quickly and stably heat the water in the tank to the preset temperature, the heating element needs to be positioned in a specific area to ensure that the heat generated by the heating element is effectively used to heat the water in the tank. However, in actual manufacturing, there may be misalignment between the position of the heating element and the water tank, resulting in the ineffective utilization of the heat generated by the heating element.

[0042] Therefore, refer to Figures 1 to 4 To address the aforementioned problems, this invention proposes a cup assembly detection device for detecting cup assemblies, wherein the cup assembly includes a heating component and a water tank fitted to the heating component, and the cup assembly detection device includes:

[0043] The main control device 10 is electrically connected to the heating component; the main control device 10 is used to control the operation of the heating component.

[0044] A first temperature detection device 20 is electrically connected to the main control device 10 at its output terminal; the first temperature detection device 20 is used to detect the operating temperature of the heating component and output a first temperature detection signal.

[0045] The second temperature detection device 30 is electrically connected to the main control device 10 at its output terminal; the second temperature detection device 30 is used to detect the temperature of the liquid in the water tank and output a second temperature detection signal.

[0046] A power detection device 40 is provided, the input terminal of which is electrically connected to the power supply terminal of the heating component, and the output terminal of which is electrically connected to the main control device 10; the power detection device 40 is used to detect the operating power of the heating component and output a power detection signal.

[0047] The main control device 10 is further configured to confirm that the fit between the heating component and the water tank is unqualified when the working time of the heating component reaches a preset time and the quotient of the difference between the first temperature value corresponding to the first temperature detection signal and the second temperature value corresponding to the second temperature detection signal and the power value corresponding to the power detection signal is greater than a preset thermal resistance.

[0048] It's important to understand that in cup components equipped with heating systems, the heating element is typically implemented using a heating plate, while the water tank is made of a material that conducts heat easily. Specifically, thermal grease is evenly applied to one side of the heating plate, then the heating plate is attached to the water tank and pressed firmly. The thermal grease is then heated and cured, thus enabling the heating plate to heat the water tank.

[0049] In this embodiment, the main control device 10 can be implemented using an FPGA (Field Programmable Gate Array), PLC (Programmable Logic Controller), MCU (Microcontroller Unit), DSP (Digital Signal Processor), or SOC (System on Chip). The main control device 10 can control the power supply circuit of the heating component by controlling switching devices such as relays, thereby controlling the operating state of the heating component.

[0050] In this embodiment, the first temperature detection device 20 can be implemented using a non-contact temperature detection device such as an infrared temperature sensor. It is understood that one side of the heating component is in contact with the water tank; therefore, the direction detected by the first temperature detection device 20 is the side of the heating component opposite to the side in contact with the water tank. The first temperature detection device 20 detects the temperature of the heating component and outputs a first temperature detection signal to the main control device 10. The main control device 10 processes the first temperature detection signal to determine the operating temperature of the heating component. Furthermore, for energy-saving purposes, the first temperature detection device 20 does not continuously detect the temperature of the heating component; instead, it only performs temperature detection under the control of the control device and outputs the first temperature detection signal when the heating component has been in operation for a preset time.

[0051] Optionally, the first temperature detection device 20 includes an infrared sensor, a third resistor R3, and a fourth resistor R4; wherein, the first end of the infrared sensor is electrically connected to the first power supply terminal, the first end of the third resistor R3, and the first end of the fourth resistor R4; the second end of the infrared sensor is electrically connected to the second end of the third resistor R3 and the main control device 10; the third end of the infrared sensor is electrically connected to the second end of the fourth resistor R4 and the main control device 10; and the fourth end of the infrared sensor is electrically connected to the ground terminal.

[0052] In this embodiment, the infrared sensor determines the surface temperature of the heating component by detecting the intensity of infrared radiation emitted by the component and outputs a temperature detection signal. The third resistor R3 and the fourth resistor R4 are both pull-up resistors. In this embodiment, the second temperature detection device 30 can be implemented using a temperature sensing probe composed of a thermistor or similar material. By extending into the water tank and directly contacting the liquid, it accurately detects the temperature of the liquid in the tank and outputs a second temperature detection signal to the main control device 10.

[0053] Optionally, the second temperature detection device 30 includes an NTC sensor, a first resistor R1, a second resistor R2, and a first capacitor C1;

[0054] Wherein, the first end of the NTC sensor is electrically connected to the first power supply end, the second end of the NTC sensor is electrically connected to the first end of the first resistor R1 and the second end of the second resistor R2; the first end of the first resistor R1 is electrically connected; the second end of the second resistor R2 is electrically connected to the first end of the first capacitor C1 and the main control device 10; the second end of the first capacitor C1 is electrically connected to the ground end.

[0055] In this embodiment, the NTC sensor is electrically connected to the first power supply terminal via a first terminal, thereby outputting a corresponding voltage signal to the main control circuit according to the temperature change. This voltage signal is the second temperature detection signal. The main control device 10 can determine the temperature of the liquid in the water tank by acquiring the second temperature detection signal. The first resistor R1 is a pull-down resistor, and the second resistor R2 and the first capacitor C1 constitute an RC filter circuit.

[0056] In this embodiment, the power detection device 40 can be implemented using a voltage detection circuit 41 combined with a current detection circuit 42, a Hall effect detection circuit, etc. It is understood that thermal resistance is a physical quantity that measures the resistance of a material or component to heat conduction, and the calculation method for thermal resistance is R = (T1 - T2) / P, which is the quotient of the difference between the first temperature value corresponding to the first temperature detection signal and the second temperature value corresponding to the second temperature detection signal, and the power value corresponding to the power detection signal. Therefore, it is necessary to detect the power consumption of the heating component using the power detection device 40 to obtain a power detection signal, and the main control device 10 confirms the power consumption value of the heating component based on the power detection signal.

[0057] Optionally, the power detection device 40 includes:

[0058] A voltage detection circuit 41 is provided, the input terminal of which is electrically connected to the power supply terminal of the heating component, and the output terminal of which is electrically connected to the main control device 10; the voltage detection circuit 41 is used to detect the operating voltage of the heating component and output a voltage detection signal.

[0059] The current detection circuit 42 is electrically connected to the power supply terminal of the heating component and electrically connected to the main control device 10. The current detection circuit 42 is used to detect the operating current of the heating component and output a current detection signal.

[0060] In this embodiment, the voltage detection circuit 41 can be implemented using a voltage divider resistor circuit, a differential amplifier circuit, or similar circuits; the current detection circuit 42 can be implemented using a current transformer circuit, a shunt detection circuit, a Hall effect detection circuit, or similar circuits. By electrically connecting the input terminal of the voltage detection circuit 41 to the power supply terminal of the heating component and the output terminal to the main control device 10, the corresponding voltage detection signal is effectively acquired and output to the main control device 10. The main control device 10 then confirms the operating voltage of the heating component based on the voltage detection signal. Similarly, by electrically connecting the input terminal of the current detection circuit 42 to the power supply terminal of the heating component and the output terminal to the main control device 10, the corresponding current detection signal is effectively acquired and output to the main control device 10. The main control device 10 then confirms the operating current of the heating component based on the current detection signal. The main control device 10 uses both the voltage and current detection signals to determine the operating power of the heating component.

[0061] Optionally, the voltage detection circuit 41 includes a fifth resistor R5, a sixth resistor R6, a seventh resistor R7, a second capacitor C2, and a first diode; the current detection circuit 42 includes an eighth resistor R8, a ninth resistor R9, a tenth resistor R10, an eleventh resistor R11, a twelfth resistor R12, a thirteenth resistor R13, a third capacitor C3, a fourth capacitor C4, and an operational amplifier.

[0062] Wherein, the first end of the fifth resistor R5 is electrically connected to the power supply terminal of the heating assembly; the second end of the fifth resistor R5 is electrically connected to the first ends of the sixth resistor R6 and the seventh resistor R7; the second end of the sixth resistor R6 is electrically connected to the ground terminal; the second end of the seventh resistor R7 is electrically connected to the first end of the second capacitor C2, the cathode of the first diode, and the main control device 10; the anode of the first diode is electrically connected to the ground terminal; the first end of the eighth resistor R8 is electrically connected to the first end of the ninth resistor R9, the power supply terminal of the heating assembly, and the second end of the tenth resistor R10; the second end of the eighth resistor R8 is electrically connected to the ground terminal; the second end of the ninth resistor R9 is electrically connected to the ground terminal; the tenth... The first end of resistor R10 is electrically connected to the first end of the third capacitor C3, which is the non-inverting input terminal of the operational amplifier; the second end of the third capacitor C3 is electrically connected to the ground terminal; the first end of the eleventh resistor R11 is electrically connected to the inverting input terminal of the operational amplifier and the second end of the twelfth resistor R12, and the second end of the eleventh resistor R11 is electrically connected to the ground terminal; the first end of the twelfth resistor R12 is electrically connected to the first end of the thirteenth resistor R13, the output terminal of the operational amplifier, and the main control device 10; the second end of the thirteenth resistor R13 is electrically connected to the ground terminal; the first end of the fourth capacitor C4 is electrically connected to the ground terminal, and the second end of the fourth capacitor C4 is electrically connected to the power supply terminal and the first power supply terminal of the operational amplifier.

[0063] In this embodiment, the voltage detection circuit 41 uses a voltage divider formed by the fifth resistor R5 and the sixth resistor R6 to detect the voltage. The current detection circuit 42 uses an operational amplifier circuit to amplify the current signal and output it to the main control device 10.

[0064] In this embodiment, the main control device 10 acquires the first temperature detection signal, the second temperature detection signal, and the power detection signal to determine the corresponding thermal resistance. A smaller thermal resistance indicates a stronger ability of the material or component to conduct heat, allowing heat to be transferred more effectively from the high-temperature region to the low-temperature region. A larger thermal resistance indicates that heat is difficult to conduct effectively through the material or component, potentially leading to localized overheating. Therefore, by comparing the calculated thermal resistance with a preset thermal resistance, the bonding status between the heating component and the water tank can be determined. Specifically: if the heating component operates for a preset duration, and the quotient of the difference between the first temperature value corresponding to the first temperature detection signal and the second temperature value corresponding to the second temperature detection signal and the power value corresponding to the power detection signal is greater than the preset thermal resistance, the bonding status between the heating component and the water tank is determined to be unqualified. If the heating component operates for a preset duration, and the quotient of the difference between the first temperature value corresponding to the first temperature detection signal and the second temperature value corresponding to the second temperature detection signal and the power value corresponding to the power detection signal is less than or equal to the preset thermal resistance, the bonding status between the heating component and the water tank is determined to be qualified. The preset duration can be selected according to different cup components, such as the volume of liquid in the cup and the power of the heating component.

[0065] By employing a cup assembly detection device, the fit between the heating element and the water tank in the cup assembly can be effectively detected. The cup assembly detection device includes a main control unit 10, a first temperature detection device 20, a second temperature detection device 30, and a power detection device 40. The main control unit 10 controls the operation of the heating element in the cup, thereby heating the liquid in the water tank. Specifically, the working time of the heating element is controlled to reach a preset duration, thus heating the liquid in the water tank. The first temperature detection device 20 detects the working temperature of the heating element and outputs a first temperature detection signal; the second temperature detection device 30 detects the temperature of the liquid in the water tank and outputs a second temperature detection signal; the power detection device 40 detects the working power of the heating element and outputs a power detection signal. The main control unit 10 calculates the corresponding thermal resistance by processing the first temperature detection signal, the second temperature detection signal, and the power detection signal, and compares the obtained thermal resistance with a preset thermal resistance to confirm whether the heat generated by the heating element in the cup is effectively utilized, thereby confirming the fit between the heating element and the water tank.

[0066] refer to Figure 4 In one embodiment of the present invention, the cup assembly detection device further includes:

[0067] A water inlet device 60, the controlled end of which is electrically connected to the main control device 10; the water inlet device 60 is used to inject liquid into the water tank according to the water inlet control signal output by the main control device 10.

[0068] A water pumping device 70, the controlled end of which is electrically connected to the main control device 10; the water pumping device 70 is used to pump liquid into the water tank according to the water pumping control signal output by the main control device 10.

[0069] A water flow detection device 50 is electrically connected to the main control device 10; the water flow detection device 50 is used to detect the flow rate of the liquid in the water inlet device 60 and output a flow rate detection signal.

[0070] In this embodiment, both the water inlet device 60 and the water pumping device 70 can be implemented using corresponding water pumps. The cup assembly detection device also includes a liquid storage tank for storing the corresponding solution, allowing the water inlet device 60 to draw the solution into the water tank, and the water pumping device 70 to draw the solution from the water tank back into the liquid storage tank. The water volume detection device 50 can be implemented using a water flow meter. By being installed at the channel of the water inlet device 60, it detects the flow rate of the liquid in the water inlet device 60, thereby confirming whether the liquid in the water tank has reached a preset volume, facilitating the setting of a preset time. Furthermore, the water volume detection device 50 effectively prevents the water tank from running dry, significantly improving the safety of the detection.

[0071] In one embodiment of the present invention, the cup assembly detection device further includes a power supply device 80. The input terminal of the power supply device 80 is electrically connected to the power input terminal, the power supply terminal of the heating assembly, the power supply terminal of the water inlet device 60, and the power supply terminal of the water pumping device 70. The output terminal of the power supply device 80 is electrically connected to the first power supply terminal and the second power supply terminal, respectively. The power supply device 80 is used to convert the first voltage input by the power input terminal into the second voltage and the third voltage, respectively, and output them.

[0072] In this embodiment, the cup assembly detection device requires power to power the main control device 10, the first temperature detection device 20, the second temperature detection device 30, the heating assembly, the water inlet device 60, the water pumping device 70, and the water volume detection device 50. The voltage required by each device may differ. Therefore, a power supply device 80 is needed to convert the input voltage so that each device receives its corresponding power supply voltage. In this embodiment, the heating assembly, the water inlet device 60, and the water pumping device 70 require the same power supply voltage, which is also the same as the input voltage at the power input terminal. Therefore, the power supply terminals of the heating assembly, the water inlet device 60, and the water pumping device 70 can be directly connected to the power input terminal. To avoid energy loss, the first, second, and third voltages are in a progressively changing relationship, i.e., the first voltage is greater than the second voltage, and the second voltage is greater than the third voltage, or the first voltage is less than the second voltage, and the second voltage is less than the third voltage.
