When the cup cover assembly 13 is closed, the detection control port IO is set to be in an output state, so that the power supply switch circuit 111 can be controlled to be switched on or switched off.

The controller 113 determines the switching state of the switching component 112 by detecting the voltage value, so that the circuit is simple and the detection is convenient.

In one embodiment, the sensing resistor R1 is connected between the sensing control port IO and the dc power supply terminal VCC, and the switch assembly 112 is connected between the sensing control port IO and the ground terminal. When the switch assembly 112 is not closed, the voltage detected by the controller 113 is the high voltage of the dc power supply terminal. When the switch assembly 112 is closed, the controller 113 detects a low voltage. In this manner, the switching state of the switching assembly 112 can be accurately determined. In one embodiment, the sense resistor R1 is integrated within the controller 113. The external circuit is simple, and the wiring is simplified.

In one embodiment, the switch assembly 112 is electrically connected to the power switching circuit 111, and the power switching circuit 111 is de-energized when the switch assembly 112 is open. The power supply switch circuit 111 and the switch component 112 are connected in series across a dc power source (not shown), which can provide dc power, such as 12V dc power. When the switch module 112 is turned off, the power supply switch circuit 111 is turned off from the dc power supply, and is turned off without receiving dc power. When the switch assembly 112 is closed, the power supply switch circuit 111 is connected to the dc power supply, and the controller 113 can control the power supply switch circuit 111 to be turned on, so that the load 120 can be powered on to operate. The power supply switch circuit 111 is powered off in hardware, so that the power supply switch circuit 111 can be effectively powered off when the cup cover assembly 13 is opened, the load 120 is powered off, and cover opening protection is safely and reliably realized.

In some embodiments, the power switch circuit 111 includes a relay RLY1 electrically connected to the load 120 and a transistor Q1 connected between the relay RLY1 and the detection control port IO, and the controller 113 controls the on/off of the relay RLY1 by controlling the on/off of the transistor Q1 through the detection control port IO. Relay RLY1 may be a single pole, single throw relay. The coil of relay RLY1 is electrically connected with controller 113, and the switch of relay RLY1 is electrically connected with load 120.

In some embodiments, the switch component 112 is connected between the transistor Q1 and the ground terminal, and controls the on/off of the transistor Q1 and the ground terminal, and controls the on/off of the power switch circuit 111 in hardware, which is simple and reliable. In one embodiment, transistor Q1 is an NPN transistor. The collector of the transistor Q1 is electrically connected to the relay RLY1, and the base of the transistor Q1 is connected to the detection control port IO through a current limiting resistor R2, and is electrically connected to the emitter of the transistor Q1 and the switch component 112 through a pull-down resistor R3.

In one embodiment, the detection resistor R1 is connected between the dc power supply terminal VCC and the current limiting resistor R2, and the switch module 112 is connected between the pull-down resistor R3 and the ground terminal. When the switch component 112 is turned off, the voltage of the detection control port IO is the voltage of the dc power supply terminal VCC. When the switch component 112 is closed, the detection resistor R1, the current limiting resistor R2, and the pull-down resistor R3 divide the voltage of the dc power supply terminal VCC, and the voltage of the detection control port IO is the total voltage of the current limiting resistor R2 and the pull-down resistor R3. In this manner, the switching state of the switching assembly 112 may be determined.

In some embodiments, the switch assembly 112 includes a first contact 1121 and a second contact 1122 that are separately provided. In one embodiment, switch assembly 112 is disposed on cup assembly 12 and lid assembly 13 is provided with an activation module 116 that is disposed to activate switch assembly 112. When lid assembly 13 is closed on cup assembly 12, trigger module 116 electrically connects first contact 1121 and second contact 1122 to close switch assembly 112. When lid assembly 13 is opened, trigger module 116 is moved away from switch assembly 112, first contact 1121 and second contact 1122 are opened, and switch assembly 112 is opened. Through the setting of the switch component 112 and the trigger module 116, the on-off of the power supply switch circuit 111 can be controlled from the hardware, so that the cover-opening protection of the food processor 10 can be realized safely and reliably.

In one embodiment, the first contact 1121 is connected to the emitter of a transistor Q1 and the second contact 1122 is connected to ground. When lid assembly 13 is closed on cup assembly 12, first contact 1121 and second contact 1122 are electrically connected, the emitter of transistor Q1 is grounded, and controller 113 can control the on/off of transistor Q1 to control the on/off of relay RLY 1. When the cup lid assembly 13 is opened, the first contact 1121 and the second contact 1122 are opened, the emitting electrode and the grounding end of the triode Q1 are disconnected from hardware, the triode Q1 is cut off, and the relay RLY1 is powered off and opened, so that a power supply line from the power supply 110 to the load 120 is disconnected, the load 120 is powered off, and the cover opening protection is realized.

In some embodiments, switch assembly 112 may be disposed on top of handle 26 of cup assembly 12 and trigger module 116 may be disposed on the bottom of lid assembly 13.

In step 202, the voltage of the detection control port IO is detected. In step 203, it is determined whether the voltage of the detection control port IO is at a low level. When the switch module 112 is turned off, the voltage at the detection control port IO is the voltage at the dc power supply terminal VCC, and is at a high level. When the switch component 112 is closed, the voltage of the detection control port IO is lower than the voltage of the dc power supply terminal VCC and is at a low level. The high and low levels may be determined by comparing the detected voltage to a threshold voltage.

In step 204, if the voltage of the detection control port IO is low level, the detection control port IO is set to an output state. When the voltage at the detection control port IO is low, the switch assembly 112 is closed, so that the lid assembly 13 is closed. When the cup cover assembly 13 is closed, the detection control port IO is set to be in an output state. If the voltage of the detection control port IO is at a high level, the voltage of the detection control port IO is continuously detected, and the step returns to the step 202.

In step 205, after the detection control port IO is set to be in the output state, a control signal is output to control the on/off of the power supply switch circuit 111. The power supply switching circuit 111 may be turned on or off according to the function, thereby controlling the operation or non-operation of the load 120.
