[0002] Electric kettles and electric cups are commonly used in household appliances. For example, handheld coffee makers often have built-in electric cups that quickly provide hot water for brewing coffee. Electric cups typically use heating elements such as heating plates or heating tubes. To ensure the heating element can quickly heat the water in the cup to the preset temperature, it needs to be positioned in a specific area to ensure the heat generated is effectively used to heat the water.

[0016] The base has a fixing groove at the bottom, and the main support body abuts and limits the fixing groove. The bottom of the fixing groove also has a clearance through hole so that the heating component is exposed in the clearance through hole.

[0017] The first temperature detector is fixed to the test stage and is located at the bottom of the clearance through hole.

When the heating element operates for a preset duration, the first temperature detector detects the operating temperature of the heating element and outputs a first temperature detection signal; the second temperature detector detects the temperature of the liquid in the cup body and outputs a second temperature detection signal; and the power detector detects the operating power of the heating element and outputs a power detection signal. The controller calculates the corresponding thermal resistance by processing the first temperature detection signal, the second temperature detection signal, and the power detection signal. It then compares the obtained thermal resistance with the preset thermal resistance to confirm whether the heat generated by the heating element in the cup is being effectively utilized.

[0045] Household appliances such as handheld coffee makers often have built-in electric heating cups that quickly provide hot water for brewing coffee. These heating cups typically use heating elements such as heating plates or heating tubes. To ensure the heating element can quickly heat the water in the cup to the preset temperature, it needs to be positioned in a specific area to ensure the heat generated is effectively used to heat the water. However, in actual manufacturing, there may be misalignment between the heating element and the heating cup, resulting in inefficient use of the heat. Furthermore, related technologies lack corresponding detection devices to monitor the fit between the heating element and the heating cup.

[0046] To solve the above-mentioned technical problems, this utility model proposes a detection device 100.

[0047] Reference Figures 1 to 5 , Figure 1 This is a schematic diagram of the structure of an embodiment of the detection device 100 of this utility model;

[0048] This application discloses a detection device 100 for detecting the contact state between the heating element 220 and the cup body 210 in an electric heating cup assembly 200. The electric heating cup assembly 200 includes a cup body 210 and a heating element 220 attached to the bottom of the cup body 210. The detection device 100 includes a body 10, a base 20, a water supply assembly 61, a first temperature detector 81, a second temperature detector 82, a power detector, and a controller 84. The body 10 is provided with a test platform 11, which provides the necessary space for the detection work. The body 10 also provides installation space for power supply components, heat dissipation components, and other components. The base 20 can be welded or detachably mounted on the test platform 11, and the base 20 facilitates the fixing of the electric heating cup assembly 200. The water supply assembly 61 is used to supply water to the electric heating cup assembly 200. The first temperature detector 81 detects the operating temperature of the heating element 220 and outputs a first temperature detection signal, and the second temperature detector 82 detects the water temperature in the cup and outputs a second temperature detection signal. The power detector is used to detect the operating power of the heating element 220. The controller 84 is connected to the water supply component 61, the temperature detection device 100, the heating element 220 and the power detector respectively. When the heating element 220 has been working for a preset time and the quotient of the difference between the first temperature value and the second temperature value and the power value is greater than the preset thermal resistance, the bonding state is confirmed to be unqualified.

[0049] In this application, the main body 10 is equipped with a test platform 11, which provides the necessary operating space for testing. The main body 10 also provides installation space for power supply components, heat dissipation components, and other components. It is understood that multiple spaced seats can be simultaneously installed on the test platform 11, meaning that one main body 10 can simultaneously test multiple electric heating cup assemblies 200 to improve testing efficiency. The main body 10 also has start / pause buttons for testing, as well as components such as a cooling fan and warning lights. The signal lines connecting each detector to the main controller 84 are also arranged inside the main body 10.

[0050] The cup body 210 component detection device 100 includes a controller 84, a first temperature detector 81, a second temperature detector 82, and a power detector. The controller 84 controls the heating element 220 in the cup body 210 to operate, thereby heating the liquid in the cup body 210. When the operating time of the heating element 220 reaches a preset time, the first temperature detector 81 detects the operating temperature of the heating element 220 and outputs a first temperature detection signal; the second temperature detector 82 detects the temperature of the liquid in the cup body 210 and outputs a second temperature detection signal; and the power detector detects the operating power of the heating element 220 and outputs a power detection signal. The controller 84 calculates the corresponding thermal resistance by processing the first temperature detection signal, the second temperature detection signal, and the power detection signal. It then compares the obtained thermal resistance with the preset thermal resistance to confirm whether the heat generated by the heating element 220 in the cup body 210 is effectively utilized. This confirms the fit between the heating element 220 and the cup body 210, and determines whether the electric cup assembly 200 is qualified. This process helps to screen out defective products, improve the factory pass rate of the electric cup assembly 200, and reduce customer complaints.

[0051] It should be noted that the heating element 220 has two terminals spaced apart. The heating circuit in the detection device 100 is connected to the two terminals of the heating element 220 via two terminal clamps to enable the heating circuit to conduct. The power detector can be located inside the controller 84.

[0052] The water supply assembly 61 includes a water supply pipe 611 and a water supply pump 612. The inlet end of the water supply pipe 611 is connected to the water tank 60, and the outlet end of the water supply pipe 611 extends into the interior of the cup body 210. The water supply pump 612 can be a peristaltic pump or a centrifugal pump to achieve quantitative water supply, and the water supply pipe 611 can be made of silicone tubing or PVC tubing. The first temperature detector 81 and the second temperature detector 82 can be thermocouples or resistance temperature detectors, and the power detector can be a Hall sensor or a current transformer combined with a voltage sampling circuit. The controller 84 can be selected from FPGA (Field Programmable Gate Array), PLC (Programmable Logic Controller), MCU (Microcontroller Unit), DSP (Digital Signal Processor), SOC (System on Chip), etc. The controller 84 calculates the corresponding thermal resistance by processing the first temperature detection signal, the second temperature detection signal, and the power detection signal. It then compares the obtained thermal resistance with a preset thermal resistance to confirm whether the heat generated by the heating element 220 in the cup body 210 is effectively utilized, thereby confirming the bonding state between the heating element 220 and the cup body 210. Understandably, when the temperature difference to power ratio exceeds a preset threshold, it is automatically judged as unqualified; when the temperature difference to power ratio does not exceed the preset threshold, it is automatically judged as qualified. Compared with manual inspection, this inspection device 100 improves inspection efficiency and accuracy, solves the problem that traditional methods cannot objectively quantify bonding quality, and achieves automated inspection of the bonding state by using thermal resistance parameters as a judgment standard.

[0053] Optionally, the first temperature detector 81 is an infrared sensor. The infrared sensor determines the surface temperature of the heating element 220 by detecting the intensity of infrared radiation emitted by the heating element 220 and outputs a temperature detection signal. The second temperature detector 82 can be implemented using a temperature sensing probe composed of a thermistor or similar material. By extending into the cup 210 and directly contacting the liquid, it accurately detects the temperature of the liquid in the cup 210 and outputs a second temperature detection signal. The second temperature detector 82 can be an NTC sensor. In this embodiment, the power detector can be implemented using a voltage detection circuit combined with a current detection circuit, 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. The thermal resistance is calculated as 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 element 220 using a power detector to obtain a power detection signal, and the controller 84 confirms the power consumption value of the heating element 220 based on the power detection signal.

[0054] In this embodiment, the controller 84 determines the corresponding thermal resistance by acquiring the first temperature detection signal, the second temperature detection signal, and the power detection signal. A lower 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 higher 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 suitability of the fit between the heating element 220 and the cup body 210 can be confirmed. Specifically: if the heating element 220 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 a preset thermal resistance, then the bonding state between the heating element 220 and the cup body 210 is deemed unqualified; if the heating element 220 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 a preset thermal resistance, then the bonding state between the heating element 220 and the cup body 210 is deemed qualified. The preset duration can be selected according to different components of the cup body 210, such as the volume of liquid in the cup body 210 or the power of the heating element 220.

[0055] Reference Figure 6In one embodiment of this application, a water tank 60 is provided inside the body 10, and the water supply assembly 61 includes a water supply pipe 611 and a water supply pump 612. The inlet end of the water supply pipe 611 is connected to the water tank 60, and the outlet end of the water supply pipe 611 extends into the electric heating cup assembly 200. The water tank 60 can be made of stainless steel or food-grade plastic, and its volume is designed according to the testing requirements. The water supply pipe 611 is preferably a flexible food-grade silicone tube, which can be connected to the water tank 60 via a quick-release connector. The water supply pump 612 can be a peristaltic pump, a centrifugal pump, or a micro diaphragm pump. In one embodiment, a pressure sensor can also be equipped to monitor the water pressure in real time. Specifically, the water tank 60 is integrated inside the body 10 as an independent water storage unit, forming a closed water supply system through the water supply pipe 611. When the water supply pump 612 is working, it generates stable water pressure, allowing water to be accurately injected into the cup body 210. The water supply pipe 611 can be arranged in a ring to avoid interference with the moving parts of the testing device 100. The resulting automated water supply system can improve detection efficiency and reduce the error in water supply volume compared to manual water filling.

[0056] The technical solution of this embodiment achieves precise quantitative water supply during the testing process. The water tank 60 ensures a continuous water supply, the water supply pipe 611 establishes a directional delivery channel, and the water supply pump 612 ensures stable water flow pressure. This solves the problems of low efficiency and inaccurate water volume control in traditional testing, making the water supply process fully automated and highly repeatable. In particular, the adoption of a closed pipeline design effectively avoids external contamination and ensures consistent water supply conditions for each test, providing stable initial conditions for subsequent temperature testing.

[0057] Reference Figure 6 In one embodiment of this application, the water supply assembly 61 further includes a flow detector 613, which is located on the water supply pipe 611 and connected to the controller 84. The flow detector 613 can be a common flow measurement device such as an electromagnetic flow meter, a turbine flow meter, or an ultrasonic flow meter. Specifically, an electromagnetic flow meter detects flow by measuring the induced electromotive force generated when a conductive fluid cuts magnetic lines of force; a turbine flow meter calculates flow by detecting the rotational speed of the turbine driven by the fluid; and an ultrasonic flow meter measures flow velocity using the time-of-flight method or the Doppler effect. The flow detector 613 is preferably installed in a straight pipe section between the outlet of the water supply pump 612 and the inlet of the electric heating cup assembly 200 to ensure measurement accuracy. The controller 84 receives the flow signal through an analog input module or a digital communication interface and adjusts the rotational speed or start / stop frequency of the water supply pump 612.

[0058] The technical solution of this embodiment monitors the water supply flow rate in real time by setting a flow detector 613 in the water supply pipe 611 and feeding the data back to the controller 84. The controller 84 dynamically adjusts the operating parameters of the water supply pump 612 by comparing the deviation between the set flow rate and the actual flow rate. This closed-loop control method effectively overcomes the problem of unstable flow rate caused by factors such as performance fluctuations of the water supply pump 612, ensuring that the water supply is accurately maintained within the set range during the testing process, improving the flow control accuracy, and providing more reliable testing conditions for the performance testing of the electric heating cup assembly 200.

[0059] Reference Figures 5 to 8 In one embodiment of this application, the bottom of the cup body 210 is provided with a drain hole 211. The detection device 100 also includes a drain assembly 70, which includes a drain pipe 71 and a drain pump 73. The two ends of the drain pipe 71 are respectively connected to the drain hole 211 and the water tank 60. The drain pump 73 is connected to the controller 84. The drain hole 211 can be set as a circular or square through hole, and the hole diameter range is designed according to actual needs. The edge of the hole can be chamfered to avoid residual water accumulation. The drain pipe 71 can be a flexible silicone tube or a rigid PVC tube, and its inner diameter matches the drain hole 211. The drain pump 73 can be a micro centrifugal pump. The controller 84 controls the start, stop and speed of the drain pump 73 through a PWM signal. The drain signal can be set to be automatically triggered after the detection is completed or manually triggered by an external button. The water tank 60 can be equipped with a water level sensor connected to the controller 84. When the water level reaches the upper limit, the draining will automatically stop.

[0060] The technical solution of this embodiment realizes the automated discharge of residual water after the test is completed by setting up a drain pipe 71 and a drain pump 73. The drain pipe 71 connects the drain hole 211 to the water tank 60 to form a closed loop system, so that the test water can be recycled and water resources are reduced. The structural design of the drain component 70 takes into account both drainage efficiency and equipment compactness. The position setting of the drain hole 211 ensures that there is no water residue in the cup.

[0061] Reference Figure 4 and Figure 5 ,as well as Figures 7 to 8In one embodiment of this application, the electric heating cup assembly 200 further includes a support frame. The support member 230 includes a support body 231 and a plurality of support portions 233 connected to the body. Each support portion 233 is connected to the outer wall of the cup body 210. The support body 231 has an annular structure and is located at the bottom of the heating element. The bottom of the base 20 is provided with a fixing groove 21, and the support body 231 abuts against and limits the fixing groove 21. The bottom of the fixing groove 21 is also provided with a clearance through hole 22 so that the heating element 220 is exposed in the clearance through hole 22. The first temperature detector 81 is fixed to the test stage 11 and is located at the bottom of the clearance through hole 22. The support body 231 can be made of stainless steel or aluminum alloy to form an annular structure, and its inner diameter is larger than the outer diameter of the heating element to achieve an enclosed positioning. The support portions 233 can be configured as 3-6 L-shaped metal pieces evenly distributed along the circumference, which are connected to the outer wall of the cup body 210 by welding or bolts. The depth of the fixing groove 21 can be designed to be 5-10mm, forming a conical surface fit with the support body 231. The diameter of the clearance through hole 22 is 2-5mm larger than the projected area of ​​the heating element, and the edges are chamfered to avoid interference. The first temperature detector 81 can be an infrared temperature sensor, and the distance between its detection surface and the bottom of the clearance through hole 22 is maintained within the range of 3-8mm.

[0062] The technical solution of this embodiment achieves millimeter-level positioning accuracy through the cooperation of the annular support body 231 and the conical fixing groove 21, with multiple support parts 233 forming a stable support structure with three or more points. When the electric heating cup assembly 200 is placed in the base 20, the support body 231 automatically centers along the fixing groove 21, making the central axis of the heating component 220 coincide with the axis of the clearance through hole 22. Thus, the temperature detection device 100 can directly obtain the temperature of the central region of the radiant heat field of the heating element. The design of the central axis of the fixing groove 21 and the clearance through hole 22 coinciding with the central axis achieves precise positioning while avoiding the structural strength loss problem of opening additional detection windows.

[0063] Reference Figures 1 to 5 In one embodiment of this application, the detection device 100 further includes a mounting base 30, which is vertically and flexibly disposed on the top of the base 20. The mounting base 30 is provided with a first mounting hole 31 and a second mounting hole 33. One end of the water supply pipe 611 near the cup body 210 is fixed through the first mounting hole 31, and the second temperature detector 82 is fixed through the second mounting hole 33. The mounting base 30 may be made of aluminum alloy or engineering plastic, and its lifting method includes, but is not limited to, manual adjustment by threaded rod engaging with the detection table; automatic lifting by electric push rod connecting to the base 20; or position adjustment by sliding rail engaging with the base 20. The first mounting hole 31 may be configured as a through-hole structure with a rubber bushing for clamping and fixing the water supply pipe 611. The second mounting hole 33 may be configured as a mounting hole with a locking screw for precisely fixing the probe position of the second temperature detector 82.

[0064] The technical solution of this embodiment, through the design of the height-adjustable mounting base 30, achieves height adjustability of the water supply pipe 611 and the temperature detection device 100, enabling it to adapt to electric heating cup assemblies 200 of different specifications, and also facilitating the insertion and removal of the heating cup assembly into or out of the base 20. The first mounting hole 31 radially limits the water supply pipe 611, effectively preventing pipe displacement caused by water flow impact. The second mounting hole 33 ensures a constant distance between the temperature probe and the cup body 210, improving the accuracy of the detection data. The lifting stroke of the mounting base 30 can be designed according to the height range of common electric heating cup assemblies 200, and the distance between the two mounting holes should ensure that the temperature probe and the water outlet do not interfere with each other.

[0065] Reference Figures 1 to 5 In one embodiment of this application, the testing device 100 further includes a lifting assembly 40, which includes a support base 41 and a guide rod. The support base 41 is mounted on the test bench 11 by screws or clips and is located on one side of the base 20. The support base 41 includes a support plate 411 mounted on the test bench 11 and a guide plate 413 connected to one end of the support. The guide plate 413 is located above the mounting base 30. The two ends of the guide post 43 are connected to the test bench 11 and the guide plate 413, respectively. The mounting base 30 is provided with a guide hole 35, and the guide post 43 passes through the guide hole 35. The support plate 411 can be made of metal sheet and fixed to the test bench 11 by bolts. Its thickness is selected according to the load-bearing requirements. The guide plate 413 and the support plate 411 are connected by welding or screws to form an L-shaped structure. The guide post 43 preferably has a chrome-plated optical axis and a clearance fit with the guide hole 35. A self-lubricating copper sleeve can be provided in the guide hole 35 to reduce the coefficient of friction.

[0066] The technical solution of this embodiment achieves precise positioning of the mounting base 30 through a rigid guide structure. The support base 41 and the base 20 are set separately, reducing the impact on the base 20. The cooperation between the guide post 43 and the guide hole 35 ensures smooth movement and avoids radial swaying, so that the mounting base 30 can maintain positional accuracy during the lifting process, meeting the requirements of the detection device 100 for the positioning stability of the water supply pipe 611 and the temperature sensor.

[0067] Reference Figures 1 to 5In one embodiment of this application, the detection device 100 further includes a locking assembly 50, which includes a locking tongue 51 and a locking plate 52. The locking tongue 51 is connected to the side of the mounting base 30 and extends towards one side of the base 20. The locking plate 52 is fixed to the test table 11 and located on one side of the base 20. The locking plate 52 extends between the base 20 and the mounting base 30, and a latching position 521 is provided on the side wall of the locking plate 52. When the mounting base 30 is closed to the opening of the cup body 210, the locking tongue 51 is engaged in the latching position 521. The locking tongue 51 can be made of metal stamping or injection molding, and its extension length must ensure that the effective engagement distance with the latching position 521 is not less than 3mm. The latching position 521 of the locking plate 52 can be designed as an L-shaped groove or a barb structure, and the groove depth is adapted to the locking tongue 51. A guide slope can be provided at the end of the locking tongue 51 to facilitate alignment and insertion with the latching position 521. The locking plate 52 can be fixed to the test table 11 by bolt connection or welding. The installation position must be precisely aligned with the movement trajectory of the locking tongue 51.

[0068] In this embodiment, the locking assembly 50 positions and fixes the mounting base 30. When the mounting base 30 is pressed down to the working position, the locking tongue 51 and the latch 521 form a rigid constraint, effectively resisting vibration or external force interference generated during the detection process. The meshing surfaces of the locking tongue 51 and the latch 521 generate a normal constraint force, limiting the displacement of the mounting base 30 in the horizontal and vertical directions, thus avoiding the positioning deviation problem between the temperature detection device 100 and the water supply assembly 61 caused by the displacement of the mounting base 30. There are two locking tongues 51 and two latch plates 52, which are respectively connected to the two ends of the mounting base 30 along its length. The two latch plates 52 are located on opposite sides of the base 20, and are arranged symmetrically at 180° with respect to the center of the base 20. The symmetrically distributed locking mechanism achieves force balance. When the mounting base 30 is closed, the locking tongues 51 on both sides simultaneously engage with the latches 521 of the corresponding latch plates 52. This creates a bidirectional locking force, ensuring that the mounting base 30 is subjected to uniform force in the vertical direction, effectively avoiding the misalignment problem caused by unilateral locking. Compared with a single-point locking structure, this design effectively improves the positioning accuracy of the mounting base 30 and the electric heating cup assembly 200, preventing displacement caused by vibration during testing.

[0069] The buffer 53 further reduces the impact force during closing. Tests show that this structure extends the service life of the latch 51. The buffer 53 can be made of elastic materials such as rubber, silicone, or polyurethane, and can be designed as a cylindrical, hemispherical, or sheet-like structure. The buffer 53 is fixed to the top of the latch by adhesive or snap-fit. The buffer 53 can be configured as a multi-layer composite structure, for example, with an outer layer of wear-resistant rubber and an inner layer of high-resilience sponge. When the mounting base 30 is pressed down, the buffer 53 undergoes compressive deformation to absorb mechanical impact energy. Compared with direct rigid contact, this design reduces impact load and prevents plastic deformation or cracking of the latch plate 52 and mounting base 30 due to repeated collisions.
