Description

Technical Field

[0002] With the continuous development of control technology, tremendous changes have been brought to human life, and increasingly intelligent home appliances are entering people's lives, improving their living standards. Soy milk, a popular beverage in my country, is highly nutritious and easily digested and absorbed, leading to a growing number of families using soy milk makers to make it.

[0003] In traditional soymilk maker designs, the circuit system supplying power to the motor and the detection device for ensuring the machine head and cup are properly connected are often independently configured. This results in a complex internal circuit layout with numerous internal wires, increasing the difficulty and cost of wiring during manufacturing and also increasing the probability of circuit failures. Furthermore, the relative independence of each functional module hinders the improvement of the overall integration of the soymilk maker and limits its development towards smaller and thinner designs.

[0038] To better understand the above-mentioned objectives, features, and advantages of this disclosure, the solutions disclosed herein will be further described below. It should be noted that, unless otherwise specified, the embodiments and features described herein can be combined with each other.

[0039] Numerous specific details are set forth in the following description in order to provide a full understanding of this disclosure, but this disclosure may also be implemented in other ways different from those described herein; obviously, the embodiments in the specification are only some, and not all, of the embodiments of this disclosure.

[0040] Figure 1 This is a schematic diagram of the circuit structure of a soymilk maker provided in an embodiment of the present disclosure, as shown below. Figure 1As shown, the soymilk maker includes: a machine head 1, a cup body 2, and a control module 4. The machine head 1 is attached to the cup body 2. The machine head 1 is equipped with a brushless motor 11 and a first coupler 5. The cup body 2 is equipped with a second coupler 6. The three-phase power supply terminal of the brushless motor 11 is electrically connected to the power supply terminal of the first coupler 5. The ground terminal GND of the brushless motor 11 is electrically connected to the ground terminal GND of the first coupler 5. The detection terminal S of the first coupler 5 is short-circuited to the ground terminal GND of the first coupler 5. The power supply terminal of the first coupler 5 is coupled to the power supply terminal of the second coupler 6. The power supply terminal of the second coupler 6 is electrically connected to the control module 4. The ground terminal GND of the first coupler 5 is coupled to the ground terminal GND of the second coupler 6. The detection terminal S of the first coupler 5 is coupled to the detection terminal S of the second coupler 6. The detection terminal S of the second coupler 6 is also electrically connected to the control module 4. The control module 4 is used to determine whether the machine head 1 and the cup body 2 are properly attached based on the electrical signal of the detection terminal S of the second coupler 6.

[0041] Figure 1 The control module 4 is shown in the cup body 2 only as an example. The control module 4 can also be set in other positions of the cup body 2, as long as it can meet the usage requirements of the soy milk maker. This disclosure does not limit this.

[0042] Specifically, the machine head 1 is equipped with a brushless motor 11 and a first coupler 5, and the cup body 2 is equipped with a second coupler 6. The first coupler 5 and the second coupler 6 can be, for example, five-pin couplers. The U-phase power supply terminal of the brushless motor 11 is electrically connected to the U-phase power supply terminal of the first coupler 5, the V-phase power supply terminal of the brushless motor 11 is electrically connected to the V-phase power supply terminal of the first coupler 5, the W-phase power supply terminal of the brushless motor 11 is electrically connected to the W-phase power supply terminal of the first coupler 5, and the ground terminal GND of the brushless motor 11 is electrically connected to the ground terminal GND of the first coupler 5. The brushless motor 11 is electrically connected to the control module 4 through the first coupler 5 and the second coupler 6. The control module 4 supplies power to the brushless motor 11. Because the brushless motor 11 operates with lower noise, using it to drive the machine head to rotate and grind and stir the ingredients makes the soymilk maker quieter during operation, reducing noise interference to the environment. Furthermore, the brushless motor 11 has higher working efficiency than a brushed motor, improving the overall efficiency of the soymilk maker.

[0043] To ensure that the control module 4 can simultaneously supply power to the brushless motor 11 and detect whether the machine head 1 and cup body 2 are properly connected, thus preventing malfunctions caused by improper connection of the machine head 1 and cup body 2, this embodiment of the present disclosure sets the detection terminal S of the first coupler 5 to the detection terminal S of the second coupler 6. The detection terminal S of the second coupler 6 is also electrically connected to the control module 4. Since the detection terminal S of the first coupler 5 is short-circuited to the ground terminal GND of the first coupler 5, when the machine head 1 and cup body 2 are properly connected, the first coupler 5 and the second coupler 6 are coupled. The ground terminal GND of the first coupler 5 and the first coupler 6 are short-circuited. When the detection terminal S of the first coupler 5 and the second coupler 6 form a loop, the control module 4 will receive a low-level signal and can start the running program after confirming that the head 1 and the cup body 2 are properly connected. When the head 1 and the cup body 2 are not properly connected, the first coupler 5 and the second coupler 6 are not coupled, and the ground terminal GND of the first coupler 5, the detection terminal S of the first coupler 5 and the detection terminal S of the second coupler 6 cannot form a loop. The control module 4 will receive a high-level signal and can issue an alarm message to prompt for reconnection of the head 1 after confirming that the head 1 and the cup body 2 are not properly connected, and control the stopping of the running program.

[0044] The soymilk maker provided in this embodiment has a brushless motor 11 installed in the machine head 1, reducing noise impact on the environment. The power supply terminal of the control module 4 is connected to the brushless motor 11 through the power supply terminals of the second coupler 6 and the first coupler 5, supplying power to the brushless motor 11. The detection terminal of the control module 4 is also connected through the detection terminals of the second coupler 6 and the first coupler 5 to detect whether the machine head 1 and the cup body 2 are properly connected. By integrating the control module 4, the first coupler 3, and the second coupler 6, it is possible to both supply power to the brushless motor 11 and detect whether the machine head 1 and the cup body 2 are properly connected. There is no need to set up a separate power supply device to supply power to the brushless motor or a separate detection device to detect the connection between the machine head and the cup body. This avoids the problems of complex internal circuit layout, numerous lines, difficult wiring, and high cost in soymilk makers, improves the reliability of soymilk makers, reduces manufacturing costs, and increases the integration of soymilk makers, which is conducive to the miniaturization of soymilk makers.

[0045] Figure 2 This is a schematic diagram of the circuit structure of a machine head provided in an embodiment of the present disclosure. Figure 3 This is a schematic diagram of the circuit structure of another head unit provided in an embodiment of this disclosure. Optionally, in conjunction with... Figure 2 and Figure 3 The head 1 includes multiple different heads 1 that are selectively connected to the cup body 2, and different detection resistors with different resistance values ​​are provided between the grounding terminal GND and the detection terminal S of the first coupler 5 of the different heads 1; the control module 4 is also used to determine the type of head 1 based on the different voltage signals detected by the detection terminal S of the second coupler 6.

[0046] Currently, soy milk makers offer increasingly diverse functions, no longer limited to simply making soy milk. They can also perform dry grinding and health-related functions. Different functions require different motor heads 1 that connect to the cup body 2. Each motor head 1 has a detection resistor between its grounding terminal GND and detection terminal S. When the motor head 1 is connected to the cup body 2, a circuit is formed by the grounding terminal GND of the first coupler 5, the detection resistor, the detection terminal S of the first coupler 5, and the detection terminal S of the second coupler 6. Since the resistance values ​​of the detection resistors on different motor heads 1 are different, the voltage signals transmitted to the control module 4 are also different. The control module 4 can, for example, pre-store the correspondence between voltage signals and the types of motor heads 1. Once the voltage signal is determined, the type of motor head 1 is determined by looking up a table or other methods.

[0047] Figure 2 The example shows a first detection resistor R1 provided between the ground terminal GND and the detection terminal S of the first coupler 5 of the machine head 1. Figure 3 The example shows a second detection resistor R2 disposed between the ground terminal GND and the detection terminal S of the first coupler 5 of the head 1. The resistance value of the first detection resistor R1 is different from that of the second detection resistor R2. The cup body 2 and Figure 2 The voltage signal obtained when the machine head 1 is fastened is related to the voltage signal of the cup body 2 and the voltage signal obtained when the machine head 1 is fastened. Figure 3 The voltage signals obtained when the machine head 1 is fastened are different, which can be used to distinguish the type of machine head 1.

[0048] Figure 4 This is a schematic diagram of the circuit structure of a cup body provided in an embodiment of this disclosure. Optionally, as shown... Figure 4 As shown, the outer wall of the cup body 2 is provided with a liquid level detection plate 21 for detecting the liquid level signal inside the cup body 2, and the control module 4 is electrically connected to the detection end S of the second coupler 6 through the liquid level detection plate 21.

[0049] Specifically, such as Figure 4 As shown, a liquid level detection plate 21 is provided on the outer wall of the cup body 2, which can detect the liquid level signal inside the cup body 2. In addition, the liquid level detection plate 21 is also connected to the detection end S of the second coupler 6, used to send the electrical signal of the detection end S of the second coupler 6 to the control module 4. For example, at the initial moment of starting the soymilk maker, the liquid level detection plate 21 acquires the electrical signal of the detection end S of the second coupler 6 and sends it to the control module 4, so that the control module 4 determines whether the machine head 1 and the cup body 2 are properly engaged based on the electrical signal of the detection end S of the second coupler 6. During the operation of the soymilk maker, the liquid level detection plate 21 can also send the detected liquid level signal inside the cup body 2 to the control module 4, so that the control module 4 determines the liquid level height inside the cup body 2 based on the liquid level signal.

[0050] Therefore, by using the liquid level detection plate 21 to detect the electrical signal at the detection end S of the second coupler 6 and the liquid level signal in the cup 2, time-division transmission of the electrical signal at the detection end S of the second coupler 6 and the liquid level signal in the cup 2 is realized, thereby improving control efficiency.

[0051] Figure 5 This is a schematic diagram of the circuit structure of another cup body provided in an embodiment of this disclosure. Figure 6 This is a schematic diagram of the circuit structure of another cup body provided in an embodiment of this disclosure. Optionally, in conjunction with... Figure 5 and Figure 6 The liquid level detection plate 21 includes multiple capacitor plates and a signal transmission terminal DATA. The detection terminals S of the capacitor plates and the second coupler 6 are both electrically connected to the signal transmission terminal DATA, which is electrically connected to the control module 4.

[0052] In some embodiments, Figure 5 The example shown is a processing chip 211 disposed on a liquid level detection plate 21. The processing chip 211 is electrically connected to capacitor plates, such as multiple capacitor plates. Figure 5 L1 to L6 are arranged at intervals on the liquid level detection plate 21 to form a liquid level detection area. Different capacitor plates correspond to different capacitance values. When the capacitor plates are close to the liquid, a capacitance signal will be generated. The processing chip 211 indirectly determines the liquid level signal based on the fluctuation of the capacitance value of the capacitance signal. The processing chip 211 sends the liquid level signal to the control module 4. The control module 4 executes the corresponding control program based on the liquid level signal. For example, when the liquid level reaches the set threshold, the heating device of the soymilk maker is stopped from heating the soymilk.

[0053] In other embodiments, Figure 6 The example shows that the processing chip 211 is disposed on the control module 4, for example. The liquid level detection board 21 sends the capacitance signal generated when the capacitor plate is close to the liquid to the control module 4. The control module 4 indirectly determines the liquid level signal based on the fluctuation of the capacitance value of the capacitance signal and executes the corresponding control program. For example, when the liquid level reaches the set threshold, it controls the heating device of the soymilk maker to stop heating the soymilk.

[0054] Figure 7 This is a schematic diagram of the circuit structure of another soymilk maker provided in an embodiment of this disclosure. Figure 8 This is a schematic diagram of another soymilk maker provided in an embodiment of this disclosure. Optionally, combined with... Figure 7 and Figure 8The soymilk maker also includes a base 3, with a cup body 2 detachably mounted on the base 3. The cup body 2 is equipped with a third coupler 7. The base 3 is equipped with a control module 4 and a fourth coupler 8. The control module 4 includes a first control unit 41 and a second control unit 42, which are communicatively connected. The power supply terminal of the second coupler 6 is connected to the power supply terminal of the third coupler 7 via a cable. The power supply terminal of the third coupler 7 is coupled to the power supply terminal of the fourth coupler 8. The power supply terminal of the fourth coupler 8 is connected to the power supply terminal of the first control unit 41 via a cable. The ground terminal GND of the second coupler 6 is connected to the third coupler 8 via a cable. The grounding terminal GND of coupler 7 is connected by a cable. The grounding terminal GND of the third coupler 7 is coupled to the grounding terminal GND of the fourth coupler 8. The grounding terminal GND of the fourth coupler 8 is connected to the grounding terminal GND of the second control unit 42 by a cable. The signal transmission terminal DATA of the liquid level detection plate 21 is connected to the signal transmission terminal DATA of the third coupler 7 by a cable. The signal transmission terminal DATA of the third coupler 7 is coupled to the signal transmission terminal DATA of the fourth coupler 8. The signal transmission terminal DATA of the fourth coupler 8 is connected to the signal transmission terminal DATA of the second control unit 42 by a cable.

[0055] Specifically, in the embodiments of this disclosure, the cup body 2 and the base 3 of the soy milk maker are set separately. The cup body 2 is detachably installed on the base 3, and the control module 4 is set on the base 3 to avoid the control module 4 being affected by the liquid in the cup body 2, thereby improving the reliability of the control module 4.

[0056] The control module 4 may include, for example, a first control unit 41 and a second control unit 42. The first control unit 41 may be, for example, a power board for high-voltage control, supplying power to the brushless motor 11. The second control unit 42 may be, for example, a control board for low-voltage control, supplying power to the liquid level detection board 21. It is understood that the first control unit 41 and the second control unit 42 may also be other types of devices, and this embodiment of the present disclosure does not limit them.

[0057] For example, the third coupler 7 and the fourth coupler 8 can be eight-pin couplers. The first control unit 41 is connected to 220V AC power and converts the 220V AC power into a first voltage, such as the operating voltage of the brushless motor 11. The first voltage is transmitted to the U-phase power supply terminal, V-phase power supply terminal and W-phase power supply terminal of the fourth coupler 8 through the U-phase power supply terminal, V-phase power supply terminal and W-phase power supply terminal of the first control unit 41. The third coupler 7 is coupled to the fourth coupler 8, and then the third coupler... The power supply terminals of the U-phase, V-phase, and W-phase of the device 7 are transmitted to the power supply terminals of the second coupler 6. The power supply terminals of the second coupler 6 are then transmitted to the power supply terminals of the first coupler 5. The power supply terminals of the first coupler 5 are electrically connected to the power supply terminals of the brushless motor 11 to supply power to the brushless motor 11.

[0058] For example, when the processing chip 211 is installed on the liquid level detection board 21, the second control unit 41 needs to supply power to the liquid level detection board. The first control unit 41 converts 220V AC power into a second voltage, such as the operating voltage of the second control unit 42. The second voltage is transmitted through the power supply terminal VCC of the second control unit 42 to the power supply terminal VCC of the fourth coupler 8, and then through the power supply terminal VCC of the third coupler 7 to the power supply terminal VCC of the liquid level detection board, so as to supply power to the liquid level detection board 21.

[0059] Optionally, such as Figure 7 As shown, the base 3 also includes a human-computer interaction module, which is electrically connected to the second control unit 42. The power supply terminal VCC of the first control unit 41 is electrically connected to the power supply terminal VCC of the second control unit 42.

[0060] Specifically, such as Figure 7 As shown, the base 3 also includes a human-machine interface module. When the second control unit 42 detects a malfunction in the soymilk maker, it can provide feedback to the user through the display screen, indicator lights, or voice prompts on the human-machine interface module. The user can also input various commands into the soymilk maker through the human-machine interface module to meet diverse user needs. The human-machine interface module can also display the working status of the soymilk maker so that the user can understand the operation of the soymilk maker. For example, the first control unit 41 can convert 220V AC power into the working voltage of the second control unit 42, and the second control unit 42 supplies power to the human-machine interface module.

[0061] For example, the human-computer interaction module and the second control unit 42 can be integrated on a printed circuit board to reduce the number of connecting wires and improve the integration of the soymilk maker.

[0062] Optionally, such as Figure 7 As shown, the soymilk maker also includes a temperature detection device 23 installed on the cup body 2, which is electrically connected to the control module 4 through the liquid level detection plate 21.

[0063] For example, such as Figure 7 As shown, the temperature detection device 23 can be, for example, an NTC (Negative Temperature Coefficient) temperature sensor. The temperature detection device 23 can directly detect the liquid temperature in the cup body 2, or indirectly detect the liquid temperature in the cup body 2 by detecting the temperature of the cup body 2. The specific detection method is not limited in this embodiment.

[0064] Figure 9 This is a schematic diagram of the circuit structure of another soymilk maker provided in an embodiment of this disclosure. Optionally, combined with... Figure 8 and Figure 9 The soymilk maker also includes a base 3, with a cup body 2 detachably mounted on the base 3. The cup body 2 is equipped with a third coupler 7, and the base 3 is equipped with a control module 4 and a fourth coupler 8. The power supply terminal of the second coupler 6 is connected to the power supply terminal of the third coupler 7 via a cable. The power supply terminal of the third coupler 7 is coupled to the power supply terminal of the fourth coupler 8. The power supply terminal of the fourth coupler 8 is connected to the power supply terminal of the control module 4 via a cable. The grounding terminal GND of the second coupler 6 is connected to the grounding terminal GND of the third coupler 7 via a cable. The grounding terminal GND of the third coupler 7 is coupled to the grounding terminal GND of the fourth coupler 8. The grounding terminal GND of the fourth coupler 8 is connected to the grounding terminal GND of the control module 4 via a cable. The detection terminal S of the second coupler 6 is connected to the signal transmission terminal DATA of the third coupler 7 via a cable. The signal transmission terminal DATA of the third coupler 7 is coupled to the signal transmission terminal DATA of the fourth coupler 8. The signal transmission terminal DATA of the fourth coupler 8 is connected to the signal transmission terminal DATA of the control module 4 via a cable.

[0065] Specifically, in combination Figure 8 and Figure 9 In the embodiments of this disclosure, the cup body 2 and the base 3 of the soy milk maker are set separately. The cup body 2 is detachably installed on the base 3, and the control module 4 is set on the base 3 to avoid the control module 4 being affected by the liquid in the cup body 2 and to improve the reliability of the control module 4.

[0066] The control module 4 is used to supply power to the brushless motor 11. The operating voltage of the brushless motor 11 provided by the control module 4 is output to the power supply terminal of the brushless motor 11 through the power supply terminal of the fourth coupler 8, the power supply terminal of the third coupler 7, the power supply terminal of the second coupler 6 and the power supply terminal of the first coupler 5, so as to supply power to the brushless motor 11.

[0067] The control module 4 is also electrically connected to the detection terminal S of the second coupler 6 through the signal transmission terminal DATA of the fourth coupler 8 and the signal transmission terminal DATA of the third coupler 7, so that the control module 4 can obtain the electrical signal of the detection terminal S of the second coupler 6 and determine whether the machine head 1 and the cup body 2 are properly fastened based on the electrical signal of the detection terminal S of the second coupler 6.

[0068] Figure 10 This is a schematic diagram of another cup structure provided in an embodiment of this disclosure. Optionally, as... Figure 10 As shown, the outer wall of the cup body 2 is provided with a liquid level detection plate 21 for detecting the liquid level signal inside the cup body 2. The control module 4 is integrated on the liquid level detection plate 21, and the liquid level detection plate 21 is electrically connected to the detection end S of the second coupler 6.

[0069] Specifically, such as Figure 10 As shown, a liquid level detection plate 21 is provided on the outer wall of the cup body 2. The liquid level detection plate 21 can detect the liquid level signal inside the cup body 2. The liquid level detection plate 21 can be integrated with the control module 4. The detection end S of the liquid level detection plate 21 is electrically connected to the detection end S of the second coupler 6. The liquid level detection plate 21 is used to detect the electrical signal of the detection end S of the second coupler 6 and send the electrical signal of the detection end S of the second coupler 6 to the control module 4. The control module 4 determines whether the machine head 1 is properly engaged based on the electrical signal of the detection end S of the second coupler 6.

[0070] Therefore, by integrating the control module 4 onto the liquid level detection board 21, the number of wiring harnesses in the soymilk maker is reduced, and the integration level of the soymilk maker is improved.

[0071] Optionally, such as Figure 7 As shown, the soymilk maker also includes a base 3, with the cup body 2 detachably mounted on the base 3. The cup body 2 is provided with a third coupler 7, and the base 3 is provided with a control module 4 and a fourth coupler 8. The soymilk maker also includes a heating device 22, the heating end of the heating device 22 is connected to the heating power supply end of the third coupler 7 via a cable, the heating power supply end of the third coupler 7 is coupled to the heating power supply end of the fourth coupler 8, and the heating power supply end of the fourth coupler 8 is electrically connected to the heating power supply end of the control module 4. The power supply end of the second coupler 6 is connected to the power supply end of the third coupler 7 via a cable, the power supply end of the third coupler 7 is coupled to the power supply end of the fourth coupler 8, and the power supply end of the fourth coupler 8 is connected to the power supply end of the control module 4 via a cable.

[0072] Specifically, such as Figure 7As shown, the cup body 2 of the soymilk maker is also equipped with a heating device 22, which is used to heat the liquid in the cup body 2. The heating power supply terminals of the heating device 22 may include, for example, a first heating power supply terminal H1 and a second heating power supply terminal H2. The first heating power supply terminal H1 of the control module 4 is connected to the first heating power supply terminal H1 of the fourth coupler 8 via a cable. The second heating power supply terminal H2 of the control module 4 is connected to the second heating power supply terminal H2 of the fourth coupler 8 via a cable. The first heating power supply terminal H1 of the fourth coupler 8 is coupled to the first heating power supply terminal H1 of the third coupler 7. The second heating power supply terminal H2 of the fourth coupler 8 is coupled to the second heating power supply terminal H2 of the third coupler 7. The first heating power supply terminal H1 of the third coupler 7 is connected to the first heating terminal H1 of the heating device 22 via a cable. The second heating power supply terminal H2 of the third coupler 7 is connected to the second heating terminal H2 of the heating device 22 via a cable. Therefore, the control module 4 converts the connected 220V AC power into the working voltage of the heating device 22, and supplies power to the heating device 22 through the heating power supply terminal of the fourth coupler 8 and the heating power supply terminal of the third coupler 7.

[0073] The control module 4 also converts the connected 220V AC power into the working voltage of the brushless motor 11, and supplies power to the brushless motor 11 through the power supply terminals of the control module 4, the third coupler 7, the fourth coupler 8, the second coupler 6, and the first coupler 5.

[0074] The soymilk maker provided in this embodiment features a brushless motor in the machine head, reducing noise impact on the environment. Through the connection of the control module, the first coupler, and the second coupler, the control module can both power the brushless motor and detect whether the machine head and cup are properly connected. This eliminates the need for a separate power supply for the brushless motor and a separate detection device to check the connection between the machine head and the cup, avoiding the problems of complex internal circuit layout, numerous lines, difficult wiring, and high cost in soymilk makers. This improves the reliability of the soymilk maker and its integration, which is conducive to the miniaturization of soymilk makers.
