The driving circuit 110 receives a control signal through the controlled terminal 119 of the driving circuit 110, and the control signal is used for controlling the working state of the driving circuit 110.

The switch circuit 120 includes a switch S1, the switch S1 includes a first end 121 and a second end 122 opposite to each other, the first end 121 is electrically connected to the controlled end 119 of the driving circuit 110, and the cup assembly 81 is in a closed state to trigger the switch S1 to close.

When the cup cover is closed, the switch is triggered to be closed, and when the cup cover is opened, the switch is opened. The switch can be arranged on the base or the cup body. In some embodiments, switch S1 comprises a mechanical switch that is closed by pressing. When the cup assembly 81 is in the closed position, the mechanical switch is pressed closed.

The control circuit 130 includes a detection port electrically connected to the switch S1, and a control port electrically connected to the second terminal 122 of the switch S1, and the control circuit 130 detects the open/close state of the switch S1 through the detection port, and outputs a control signal to the controlled terminal 119 of the driving circuit 110 via the switch S1 when the switch S1 is detected to be closed. If the cup assembly 81 is in the closed state, the switch S1 is triggered to be closed, and the detection port detects the closed state of the switch S1, the control port of the control circuit 130 outputs a control signal, and the control signal is transmitted to the driving circuit 110 through the switch S1 to control the operating state of the driving circuit 110.

In the embodiment of the application, the switch S1 is connected between the control circuit 130 and the driving circuit 110, and even if the control circuit 130 misjudges that the switch S1 is closed when the switch S1 is turned off, the driving circuit 110 is disconnected from the control circuit 130 due to the turn-off of the switch S1, and does not operate, so that the safety is improved. The control circuit 130 can determine whether the cup assembly 81 is closed or not by detecting the open/close state of the switch S1, and when the switch S1 is closed and the switch circuit 120 is turned on, the control signal outputted from the control circuit 130 reaches the driving circuit 110 to drive the load 150 such as the motor to operate. In addition, the switch S1 of the switch circuit 120 carries the driving signal output by the control circuit 130, and the voltage of the driving signal is low, so that the requirement for the current carrying capacity of the switch S1 is greatly reduced, and the cost of the components of the switch S1 is reduced.

In one embodiment of the present application, the detecting port includes a first detecting port P1.0, the first detecting port P1.0 is electrically connected to the second end 122 of the switch S1, the control circuit 130 detects the open/close state of the switch S1 through the first detecting port P1.0, and the first detecting port P1.0 and the control port are the same port or different ports. In one embodiment, the first detection port P1.0 and the control port are the same port, and if the first detection port P1.0 detects that the switch S1 is in the closed state, the first detection port P1.0 serves as a control port to output a control signal to the switch S1. The control circuit 130 can complete the state detection and the control signal output of the switch S1 on one port, so as to reduce the occupation of the port. The first detection port P1.0 may be an I/O port. In other embodiments, the first detection port P1.0 and the control port are different ports, the first detection port P1.0 detects the open/close state of the switch S1, and outputs a control signal to the switch S1 through the control port to detect and control the ports to be different ports, so as to simplify the control procedure. In some embodiments, the first detection port P1.0 may be an analog port independent of the control port.

In one embodiment, the food processor circuit 100 includes a high-level end P1.1, the switch S1 includes a current-limiting resistor R3, one end of the current-limiting resistor R3 is electrically connected to the high-level end P1.1, the other end is electrically connected to the second end 122 of the switch S1, the first end 121 of the switch S1 is grounded, and the first detection port P1.0 is electrically connected between the switch S1 and the current-limiting resistor R3 for detecting a level change between the switch S1 and the current-limiting resistor R3. In this way, if the current limiting resistor R3 is not connected, when the switch S1 is closed, the driving circuit 110 is connected to the high-level terminal P1.1, and the driving circuit 110 may mistakenly assume that it is a control signal, so that the wrong driving motor may start to operate. In addition, the problem that when the switch is not closed, if the current limiting resistor R3 is absent, the first detection port P1.0 will always detect a high level, and the control circuit 130 will misjudge that the switch is closed can be avoided. The current limiting resistor R1 can prevent erroneous driving of the driving circuit 110, and can reduce the probability of erroneous determination of the open/close state of the switch S1. In one embodiment, the control circuit 130 includes a high-level output port, the high-level output port is a high-level end P1.1, and the high-level output port outputs a high level and is electrically connected to the current-limiting resistor R3. The control circuit 130 includes a control chip U1, and one port of the control chip U1 is set as a high-level output port to which a current limiting resistor R3 is connected. The high-level output port may be an I/O port through which the control chip U1 outputs a high level. In another embodiment, the high-level end P1.1 of the food processor circuit 100 is provided by a switching power supply or a voltage conversion circuit outside the control circuit 130.

In one embodiment, the first detection port P1.0 and the control port are the same port, the detection port includes a second detection port P1.2 independent of the control port, the second detection port P1.2 is electrically connected to the second end 122 of the switch S1, and the control circuit 130 detects the open/closed state of the switch S1 through the second detection port P1.2. When the first detecting port P1.0 is used as the control port, the first detecting port P1.0 cannot detect the open/close state of the cup assembly 81 by detecting the close state of the switch S1 through the second detecting port P1.2 independent of the first detecting port P1.0 and determining the open/close state of the switch assembly S1 through the level change of the second detecting port P1.2, because the control port outputs the control signal.

In other embodiments, the control port is not used as a detection port, but only for outputting a control signal, and the second detection port P1.2 detects the state of the switch S1.

In one embodiment, the switch circuit 120 includes a first voltage-dividing resistor R1 and a second voltage-dividing resistor R2 connected in series, and a voltage-dividing output terminal 123 connected between the first voltage-dividing resistor R1 and the second voltage-dividing resistor R2, and the switch S1 and the first voltage-dividing resistor R1 are connected in series between the voltage-dividing output terminal 123 and a ground terminal. The voltage dividing output end 123 is electrically connected to the second detection port P1.2, and the control circuit 130 detects the open/close state of the switch S1 through the second detection port P1.2.

The first end 121 of the switch S1 is connected to one end of the second voltage-dividing resistor R2, the other end of the second voltage-dividing resistor R2 is grounded, and if the cup assembly 81 is not covered, the second detection port P1.2 determines the cover-closing state by detecting the level change of the voltage-dividing output terminal 123 connected between the first voltage-dividing resistor R1 and the second voltage-dividing resistor R2. Therefore, the two ends of the switch S1 are connected in series with a voltage dividing resistor, so that the cover closing state of the cup assembly 81 can be detected in the state of driving the load, and the safety of the user using the food processor is ensured.

In one embodiment, the current limiting resistor R3 is electrically connected between the high level output port P1.1 and the second voltage dividing resistor R2.

The first detection port P1.0 detects the open/close state of the switch S1 by detecting the high/low level. When the switch S1 is open, the first detection port P1.0 detects a high level. When the switch S1 is turned on, the first detection port P1.0 is electrically connected to the high-level terminal P1.1 through the current-limiting resistor R3, forming a loop, and the first detection port P1.0 detects the high level. When the switch S1 is closed, the first detection port P1.0 detects a low level. When the switch S1 is closed, the first detection port P1.0 is grounded through the switch S1, the current limiting resistor R3 is bypassed, the potential of the first detection port P1.0 is pulled low, and a low level is detected. The open/close state of the switch S1 is thus detected.

The second detection port P1.2 detects a voltage value of the voltage division output terminal 123 connected between the first voltage division resistor R1 and the switch S1. For example, if the AD resolution of the control chip (e.g., a single chip microcomputer) is 10 bits, the voltage value detected by the second detection port P1.2 is V × R1/(R1+ R2) × 2¹⁰And judging that the cup component 81 is well covered. Where V represents the voltage output by the high-level terminal P1.1 or the voltage output by the control port P1.0, and the voltage output by the high-level terminal P1.1 is equal to the voltage output by the control port P1.0. If the second detection is madeThe port P1.2 detects a voltage value V2¹⁰If the cup assembly 81 is not covered, the output of the control signal is stopped, and the load stops working. When the first detection port P1.0 outputs a control signal as a control port, the detection can still be performed through the second detection port P1.2, so that the on-off state of the switch S1 can be detected while the load is driven, and the safety is improved.

In one embodiment, the first voltage dividing resistor R1 is electrically connected between the first terminal 121 of the switch S1 and ground, and the driving circuit 110 is electrically connected between the first terminal 121 of the switch S1 and the first voltage dividing resistor R1, so as to ensure that the driving circuit can be normally activated by the control circuit. When the switch S1 is turned on, since the current limiting resistor R3 is electrically connected between the high level output port P1.1 and the second voltage dividing resistor R2, the first detection port P1.0 is always at a high level; when the switch S1 is closed, the level of the first detection port P1.0 is pulled low, and the control circuit 130 determines that the cup assembly 81 is closed, and outputs a control signal, which is transmitted to the driving circuit 110 connected thereto via the switch S1. In one embodiment, the control signal is provided to the driving circuit 110 only when the switch S1 is closed, and once the switch S1 is opened, the control circuit 130 determines that the cup assembly 81 is not closed, and not only stops outputting the control signal, but also outputs the control signal even if the control circuit 130 misjudges the state of the cup assembly, and since the driving circuit 110 is connected between the switch S1 and the second voltage-dividing resistor R2, the control signal cannot be transmitted to the driving circuit 110, thereby improving safety.

When the cup assembly 81 is in the closed state, the magnet arranged on the cup assembly 51 triggers the magnetic switch S2 arranged on the base 80 to be closed. The type of the switch is not limited to this, and any element that can perform the opening and closing function is included.

Step 701, after the food processor is powered on, the food processor is in a standby state, an I/O port P1.0 is set as an input state, and the input state serves as a first detection port to detect the open-close state of a switch S1; controlling a high-level output port P1.1 to output a high level; the second detection port P1.2 is an analog port (AD port), and detects the open/closed state of the switch S1.

Step 702, determining whether the I/O port P1.0 detects a low level, and if the level is detected to be a low level, determining that the cup assembly 81 is covered, and performing step 703; if the detected level is high level, the cup assembly 81 is judged not to be well covered, and the detection is continued.

And 703, judging whether a motor starting signal is received, wherein the motor starting signal is a starting signal for starting the food processor by a user or set by a function program. And if the motor starting signal is not received, continuing to wait until the motor starting signal is received.

The open/close state of the switch S1 is detected through the second detection port P1.2. IO port P1.0 is output mode and continuously outputs control signal, and because of the influence of control signal, through the change of second detection port P1.2 detection AD value, whether switch S1 is closed is confirmed, thereby whether the cup subassembly is closed is confirmed.
