As shown in fig. 1 to 5, the present invention provides a control system for a whipping device, which includes a charging module 10, a battery module 20, a control module 30, and a self-power-off module 40. The charging module 10 is used for connecting an external power source, and is configured to convert an input voltage of the external power source into a charging voltage suitable for the battery module 20. The battery module 20 is connected to the charging module 10 and is charged by the charging module 10. The self-power-off module 40 is connected between the battery module 20 and the control module 30, and the battery module 20 supplies power to the control module 30 through the self-power-off module 40. The control module 30 may determine an operating state of the whipping device and disconnect power to the battery module 20 by controlling the self-power-off module 40 in a case where the whipping device is in a non-operating state.

As such, by providing the battery module 20 in the whipping device, the flexibility of use of the whipping device can be increased. By arranging the self-power-off module 40 controlled by the control module 30 between the battery module 20 and the control module 30, the power supply of the battery module 20 can be automatically cut off when the whipping device is not operated, so that the electric energy is saved, and the standby time of the battery is prolonged.

Specifically, the whipping device can be a wall breaking machine, a food processor, a soymilk maker, a meat grinder, a juicer, or the like. The whipping device may include elements such as a device body, a cup, a motor, and a blade. A power line for connecting a power source may be disposed on the device body, an adapter may be disposed on the power line, an external power source may be connected to the whipping device via the power line, and an input voltage of the external power source is rectified by the adapter and then converted into a charging voltage suitable for the battery module 20 by the charging module 10 to charge the battery module 20. The control module 30 may be connected to the charging module 10, and the control module 30 may change the charging voltage by controlling the charging module 10. The charging module 10 may be, for example, a boost voltage boost circuit (i.e., a boost chopper circuit), such as the boost voltage boost circuit composed of an inductor L1, a diode D3 and a controllable switch unit U1 shown in fig. 3, and the controllable switch unit U1 may be, for example, a MOS transistor (metal oxide semiconductor field effect transistor). The control module 30 may include a control unit U4, the control unit U4 may include, but is not limited to, a general purpose processor, a special purpose processor, a conventional processor, a plurality of microprocessors, a controller, a microcontroller, an Application Specific Integrated Circuit (ASIC), a Field Programmable Gate Array (FPGA) circuit, any other type of Integrated Circuit (IC), and the like. The control unit U4 may control the on/off of the controllable switch unit U1 so that the output voltage via the diode D3 may be adjusted to a charging voltage suitable for the battery module 20 by the inductor L1. Furthermore, the control unit U4 may also turn on or off the charging of the battery module 20 by controlling the on-off state of the controllable switch unit U1. For example, as shown in fig. 3, in the case that the input voltage Vin of the external power source is connected, the second controllable switch Q3 and the first controllable switch Q4 are sequentially turned on, the control unit U4 is powered on, and then the control unit U4 may turn on the charging module 10 by controlling the switch unit U1, so as to start charging the battery module 20. It is understood that the charging module 10 is not limited to the boost circuit shown in fig. 3, but may also be a buck circuit (i.e., a buck converter circuit) or other charging circuit.

The battery module 20 may include a secondary battery, wherein the secondary battery may be a lithium battery or a nickel metal hydride battery, or the like. The charging voltage output by the charging module 10 may charge the secondary battery in the battery module 20. The batteries in the battery module 20 may power the control module 30. In addition, the battery may also supply power to one or more of the motor module 70, the external recoil module 60, the key module 80, the display module 90, and the cup detection module 110 shown in fig. 2. A self-power-off module 40 may be disposed between the battery module 20 and the control module 30, and the control module 30 may control the self-power-off module 40 to disconnect the power supply of the battery module 20 when the whipping device is in an inoperative state, so as to save the electric energy of the battery. In an alternative embodiment, the self-power-off module 40 may be further disposed between the battery module 20 and one or more of the display module 90, the key module 80, and the cup detection module 110, and in the case that the control module 30 determines that the whipping device is in the non-operating state, the self-power-off module 40 may be controlled to disconnect the power supply circuit between the battery module 20 and the display module 90, the key module 80, the cup detection module 110, and the control module 30 itself.

The battery module 20 may also be used to sense and/or control detailed parameters of battery charging. For example, as shown in fig. 3, the battery module 20 may include a filtering and voltage stabilizing circuit and a detection circuit, the charging voltage output by the charging module 10 passes through the filtering and voltage stabilizing circuit to charge the storage battery, the detection circuit is connected to the storage battery, and the control module 30 detects the voltage of the storage battery through the detection circuit. The filter voltage stabilizing circuit can be composed of a capacitor C3 and a zener diode ZD2 which are connected in parallel with each other, and a parallel circuit composed of a capacitor C3 and a zener diode ZD2 is connected at two ends of the battery BAT. Under the filtering action of the capacitor C3 and the voltage stabilizing action of the voltage stabilizing diode ZD2, the filtering voltage stabilizing circuit can absorb noise in the charging voltage and simultaneously avoid overhigh voltage input to the storage battery BAT. The detection circuit may be composed of a voltage dividing resistor R13, a voltage dividing resistor R14, a voltage dividing resistor R45, and a capacitor C13, and the output voltage (e.g., 8.4V) of the battery BAT can be reduced to a range recognizable by the control unit U4 (e.g., 0 to 5V) through the voltage dividing resistor, so as to be detected by the control unit U4.

Optionally, a voltage stabilizing module 50 may be further disposed between the battery module 20 and the control module 30, the key module 80, the display module 90 and the cup body detecting module 110, and the battery module 20 may sequentially supply power to the control module 30, the display module 90, the cup body detecting module 110 and the key module 80 through the auto-power-off module 40 and the voltage stabilizing module 50. The sequence of the self-power-off module 40 and the voltage stabilizing module 50 can be reasonably set according to needs. The voltage regulator module 50 may be, for example, a LDO (low dropout regulator) circuit or a DC-DC circuit. For example, the voltage stabilizing module 50 may be composed of a voltage regulator U3, and a filter capacitor C6, a filter capacitor C7 and a resistor R16 connected in parallel with the voltage regulator U3, wherein the filter capacitor C6 is connected in parallel with an input side of the voltage regulator U3, and the filter capacitor C7 and the resistor R16 are respectively connected in parallel with an output side of the voltage regulator U3. The stabilized voltage VDD output by the voltage stabilizer U3 can supply power to the control module 30, the key module 80, the display module 90, the cup detection module 110, and the like, so as to reduce the risk of damage to the above modules, and further improve the operation stability of the whipping device.

In an alternative embodiment of the present invention, the self-power-off module 40 and the control module 30 may jointly constitute a self-power-off control system. The self-powered-off module 40 may include a first controllable switch Q4, a second controllable switch Q3, a voltage dividing resistor R41, a voltage dividing resistor R42, a current limiting resistor R9, a voltage dividing resistor R10, and a voltage dividing resistor R11. The first controllable switch Q4 is used to connect the battery module 20 and the control module 30, and when an external power source is connected, the first controllable switch Q4 is also used to connect the external power source and the control module 30. The second controllable switch Q3 is connected to the control terminal of the first controllable switch Q4, and the change of state of the second controllable switch Q3 can cause the change of state of the first controllable switch Q4. The control module 30 may be connected to a control terminal of the second controllable switch Q3 and configured to control a state of the second controllable switch Q3. The first controllable switch Q4 and the second controllable switch Q3 may be MOS transistors, triodes, or the like, and in the embodiment shown in fig. 3 and 4, the first controllable switch Q4 may be, for example, a PNP triode or a PMOS transistor, and the second controllable switch Q3 may be, for example, an NPN triode or an NMOS transistor.

Specifically, as shown in fig. 3 and 4, the input terminal of the first controllable switch Q4 may be connected to a power source, which may include the battery module 20 and/or an external power source, and the output terminal of the first controllable switch Q4 may be connected to the control module 30 directly or indirectly through the regulator module 50 to the control module 30. One end of the voltage dividing resistor R41 may be connected to the input terminal of the first controllable switch Q4 (i.e., connected to the power supply), and the other end is connected to the control terminal of the first controllable switch Q4. One end of the divider resistor R42 is connected to the control end of the first controllable switch Q4, and the other end is grounded through the second controllable switch Q3. Under the condition that the second controllable switch Q3 is turned on, the voltage of the control end of the first controllable switch Q4 is pulled down under the voltage dividing action of the voltage dividing resistor R41 and the voltage dividing resistor R42, so that the first controllable switch Q4 is turned on. The control unit U4 is connected to the control terminal of the second controllable switch Q3 through the voltage dividing resistor R10, and when the control unit U4 determines that the device (e.g., the whipping device) where the self-power-off control system is located is in the non-operating state, a low level may be output to the control terminal of the second controllable switch Q3 to turn off the second controllable switch Q3, so that the first controllable switch Q4 is turned off, and the power supply circuit between the battery module 20 and the power consuming components such as the control module 30 is disconnected, and the control unit U4 is powered off, and the control system is turned off.

In an optional embodiment of the present invention, in the case of the external power source accessing to the control system, the input voltage Vin rectified by the adapter from the external power source may act on the control terminal of the second controllable switch Q3 through the current limiting resistor R9, so as to control the conduction of the first controllable switch Q4 by changing the state of the second controllable switch Q3. For example, in the case of a whipping device accessing the input voltage Vin of the adapter (i.e., powered by an external power source), the second controllable switch Q3 may be turned on by the voltage Vin, so that the first controllable switch Q4 is turned on, and the power consuming components of the control module 30, etc. powered by the battery module 20, start to power up. Therefore, the quick switching between the power supply of the battery module and the power supply of the external power supply can be realized, and the external power supply supplies power under the condition that the external power supply is connected, so that the electric energy of the battery module can be saved.

In an alternative embodiment of the present invention, the control system further comprises a key module 80, and the key module 80 can be connected to the control end of the first controllable switch Q4 to control the state of the first controllable switch Q4. Specifically, as shown in fig. 3 and 4, the KEY module may include a pull-up resistor R33, a diode D1, a diode D2, and an active switch KEY 2. One end of the active switch KEY2 may be connected to the control end of the first controllable switch Q4 through the diode D1 and the voltage-dividing resistor R42 in sequence, and the other end is grounded. The anode of the diode D1 is connected to the voltage dividing resistor R42, and the cathode of the diode D1 is connected to the active switch KEY 2. The anode of the diode D2 is connected to the detection port of the control unit U4, and the cathode of the diode D2 is connected to the active switch KEY 2. One end of the pull-up resistor R33 is connected to the output voltage VDD of the voltage regulator module 50, and the other end of the pull-up resistor 33 is connected between the control unit U4 and the diode D2. When the active switch KEY2 is pressed by a user, the active switch KEY2 is turned on from off, a loop where the diode D1, the voltage dividing resistor R41 and the voltage dividing resistor R42 are located is turned on, one end of the voltage dividing resistor R42 is pulled to the ground, the first controllable switch Q4 is turned on by utilizing the voltage dividing relationship between the voltage dividing resistor R41 and the voltage dividing resistor R42, the power supply starts to supply power to the voltage regulator U3, the output voltage VDD stabilized by the voltage regulator U3 supplies power to the power consuming elements such as the control module 30, the power consuming elements such as the control module 30 are powered on to work, and the control system starts to work. After the control module 30 starts to work, it outputs a high level to the MCU _ COT interface, so that the second controllable switch Q3 is turned on, and the second controllable switch Q3 is turned on to maintain the first controllable switch Q4 to be continuously turned on, so as to maintain the output voltage VDD of the voltage regulator U3, and at this time, the active switch KEY2 may also be released to recover to the off state. In this way, through the key module 80, when the user needs to use the whipping device, the user can manually control the whipping device to be powered on.

Further, whether the active switch KEY2 is turned on may be determined through a detection port of the control unit U4. As shown in fig. 3, wherein the active switch KEY2 may be determined to be turned off when the test port of the control unit U4 is at a high level, the active switch KEY2 may be determined to be turned on when the test port of the control unit U4 is at a low level. By detecting the active switch KEY2, the control module 30 may determine the number of times the KEY module 80 is turned on within a predetermined time period, and then control the whipping device to perform different functions.

In an optional embodiment of the present invention, the control system may further include an external recoil module 60, the external recoil module 60 is connected to the battery module 20, and the battery module 20 can output the voltage Vout to the outside through the external recoil module 60 to charge the external terminal device. The control module 30 is also configured to detect a state of charge of the external recoil module 60 and control whether the external recoil module 60 is turned on for external charging. The external kick module 60 may include a buck circuit composed of a buck chip U2, a capacitor C21, a capacitor C11, an inductor L3, a resistor R17, and a resistor R20, the control unit U4 may control the buck chip U2 to adjust the voltage output by the battery module 20 to an output voltage suitable for charging an external terminal device, and the control unit U4 may further turn on or off the charging of the terminal device by controlling the buck chip U2. It is understood that the external kick module 60 is not limited to the specific form of the buck circuit, and the external kick module 60 may also be other forms of buck circuits or other types of circuits, and the principle of the buck circuit is not described herein since it belongs to the prior art.

In an alternative embodiment of the present invention, the control system may include a motor module 70 and an external recoil module 60 respectively connected to the control module 30, and the control module 30 is further configured to determine the operating status of the motor module 70 and the external recoil module 60, and determine that the whipping device is in the non-operating status under the condition that the motor module 70 and the external recoil module 60 are both in the non-operating status. Specifically, the control module 30 may determine whether the motor in the motor module 70 is operated and whether the external recoil module 60 is charging the external terminal device according to the control relationship and the detection result of the motor module 70 and the external recoil module 60, and if it is determined that the motor in the motor module 70 is not operated and the external recoil module 60 is not charging the external terminal device at a certain time or within a preset time period, it is determined that the whipping device is in a non-operating state, and at this time, the control module 30 may disconnect the power supply circuit of the battery module 20 by controlling the self-power-off module 40. And in the case where either one of the motor module 70 and the external kickback module 60 is in the operating state, it is determined that the whipping apparatus is in the operating state. It should be noted that, as shown in fig. 3, when the input voltage Vin of the external power source is connected or the active switch KEY2 is turned on, the first controllable switch Q4 in the self-powered-down module 40 is kept turned on and is not controlled by the control module 30 to be turned off.

In an optional embodiment of the present invention, the whipping device may further be provided with a low power mode, and the control module 30 may further disconnect the power supply circuit of the battery module 20 by controlling the self-power-off module 40 under the condition that it is determined that the whipping device needs to enter the low power mode. The control module 30 may determine that the whipping device needs to enter the low power consumption mode according to an instruction of a user, or the control module 30 may determine whether the whipping device needs to enter the low power consumption mode by determining the working states of the external recoil module 60 and the motor module 70, for example, the control module 30 may determine that the whipping device needs to enter the low power consumption mode when determining that the external recoil module 60 and the motor module 70 are both in the non-working state at a certain time or within a preset time period.

IN use, as shown IN fig. 4 and 5, when the first controllable switch Q4 is IN an off state, if an external power source is connected (i.e. the USB _ IN interface is at a high level), the second controllable switch Q3 is turned on, so that the first controllable switch Q4 is turned on, and the voltage regulator U3 outputs the voltage VDD to supply power to the control system. Accordingly, when the active switch KEY2 is pressed, the active switch KEY2 turns on, so that the first controllable switch Q4 turns on, and the voltage regulator U3 starts outputting the voltage VDD to power the control system. After the control module 30 and other elements start to power on, the control module 30 may determine whether the whipping device needs to enter a low power consumption mode, if the control module 30 determines that the whipping device needs to enter the low power consumption mode, a low level is output to the MCU _ COT interface, the second controllable switch Q3 is turned off, the voltage across the voltage dividing resistor R41 is pulled high by the battery BAT, the first controllable switch Q4 is turned off, thereby cutting off the circuit between the battery BAT and the regulator U3, the module powered by the regulator U3 stops working, and the whipping device starts to enter the low power consumption mode. The whipping device will then remain in the low power mode until the user reactivates the control module 30 by turning on external power or pressing the active switch KEY2, etc.

In an optional embodiment of the present invention, the control system may further include a display module 90, the display module 90 is connected to the control module 30, and the battery module 20 supplies power to the display module 90 through the self-power-off module 40.

Specifically, the display module 90 may include leds D6-D9 and resistors R24-R27 respectively connected in series with the leds, and the leds D6-D9 are respectively connected to the control unit U4 through resistors R24-R27, so that the control unit U4 may indicate one or more of a battery level, a motor operating state, an external kickback state and an apparatus abnormal state by controlling whether the leds D6-D9 are lighted. For example, the battery level may be indicated by the number of light-emitting diodes D6-D9, or whether the external kick module 60 is kicking back an external terminal device may be indicated by whether a designated light-emitting diode is lit.

The cup detection module 110 may include a hall sensor, and a magnet may be disposed at the bottom of the cup. When the cup is placed on the equipment body, the magnet at the bottom of the cup is close to the hall sensor, and when the cup is separated from the equipment body, the magnet at the bottom of the cup is far away from the hall sensor, so that the control module 30 can detect the magnet through the hall sensor, and further determine whether the cup is separated from the equipment body.
