Referring to fig. 1, a cup lid detection circuit includes a detection plate 1b and a control plate 2 b. The detection board 1b comprises a detection board output end 11a and a detection board grounding end 11b, and the control board 2b comprises a control board end 21a and a control board grounding end 21 b. And the control board 2b is connected with the upper coupler 31b and the lower coupler 32b, specifically, the output end 11a of the detection board is connected with the control board end 21a, and the ground end 11b of the detection board is connected with the ground end 21b of the control board. The detection board 1b further comprises an active position detection module 12b, a resistor R1, a capacitor C1, a capacitor C2, a detection board output end 12a and a detection board grounding end 12 b. The active position detection module 12b is used to detect whether the cup is covered effectively, for example, a hall sensor, etc., and in the case that the active position detection module 12b includes a hall sensor, it is sometimes referred to as a hall platelet in the industry. The active position detecting module 12b includes a power supply terminal VCC, a module output terminal OUT, and a module ground terminal GND.

In order to enable the cup cover to be high in detection reliability, the embodiment of the application discloses a cup cover detection circuit. The cup lid detection circuit is described in detail below.

Referring to fig. 2 in conjunction with fig. 8, a cup lid detection circuit includes a detection board 1 and a control board 2. The cup cover detection circuit is applied to a food processor. The food processor 100 comprises a food cup assembly 10 and a main machine 20. In one embodiment, the cooking cup assembly 10 includes a cooking cup 101 and a lid 102. The cup cover 102 can be covered with the cooking cup 101. Referring to fig. 2 and 9, the detection board 1 includes a detection board output end 11a, a detection board ground end 11b, an active position detection module 12, and a power supply module 13. The control board 2 includes an I/O terminal and a control board ground terminal. The active position detection module 12 and the power supply module 13 are connected to the control board 2 through the detection board output terminal 11a and the detection board ground terminal 11 b. Of course, in some embodiments, the active position detection module 12 and the power supply module 13 may be provided as separate components, not disposed on the detection board 1, and connected to the I/O terminal of the control board 2 and the ground terminal of the control board, respectively. The active position detecting module 12 includes a power supply terminal VCC, an output terminal OUT, and a module ground terminal GND. The active position detection module 12 includes a hall sensor and the like. The active position detection module 12 is, for example, an MT8571 chip. The power supply module 13 is connected to the power supply terminal VCC of the active position detection module 12 and the module ground terminal GND. Control panel 2 includes IO1 and control panel ground terminal 22, IO1 with output OUT with power module 13 connects, control panel ground terminal 22 with module ground terminal GND connects, control panel 2 passes through IO1 receives and comes from the first output signal of output OUT, the basis first output signal judges whether active position detection module 12 is effective. The control panel 2 further supplies power to the active position detection module 12 from the power supply module 13 under the condition that the active position detection module 12 is effective, and the control panel 2 further obtains a second output signal from the output end OUT and judges whether the cover closing of the cup cover 102 is effective or not according to the second output signal.

Referring to fig. 4 and 5 in combination with fig. 2 and 6, the flow of the cup cover detection circuit is described as follows by taking the example that the active position detection module 12 includes a hall sensor: the control panel 2 may be implemented by a single chip microcomputer. The process is as follows:

Of course, depending on the active position detection module 12, the active position detection module 12 may be invalid when the first output signal is at a low level; in case the first output signal is high, the active position detection module 12 is active. In summary, the output result (e.g., high level or low level) of the first output signal is determined according to the abnormal or normal condition of the active position detection module 12. As shown in fig. 6, when the active position detection module is invalid, the control board stops outputting the signal, and the food processor does not execute any function.

Referring to fig. 4 and 5 in combination with fig. 2 and 7, in a case that the active position detection module 12 is active, the control board 2 outputs a square wave signal (PWM waveform) through the I/O terminal to charge the power supply module 13 so as to supply power to the active position detection module 12, and then detects a second output signal output by the output terminal OUT through the I/O terminal, and determines whether the lid closing is active according to the second output signal, in an embodiment, as shown in fig. 4, 5 and 7, in a case that the I/O terminal detects a high level, the control board 2 determines that the lid closing is inactive (the lid is not closed, etc.), and in this case, the control board 2 controls the food processor not to perform any function. As shown in fig. 4, 5 and 7, in a case where the control board 2 detects a low level through the I/O terminal (as shown in the IO1), the lid is valid (the lid 102 is already screwed to the food processing cup 101), and the control board 2 controls the food processing machine to perform a related function, for example, the control board 2 detects whether the lid 102 is already valid to be covered with the food processing cup 101, and in a case where the lid is valid, the food processing machine may perform a related function (that is, the related function may be opened).

As set forth above, the I/O terminal and the ground terminal of the control board 2 are connected to the corresponding terminal of the active position detection module 12 and the corresponding terminal of the power supply module 13, the output of the active position detection module 12 is detected by setting the state of the I/O terminal, and whether the active position detection module 12 is valid or not is determined according to the first output signal. Active position detection module 12 is effectual under the condition, control panel 2 detects bowl cover 102 and closes to cover effectively (bowl cover 102 and arrange the cup 101 and close), under the condition that bowl cover 102 and arrange the cup 101 lid and close, control cooking machine carries OUT corresponding function, therefore, the reliability that bowl cover 102 detected is high, for example, the control panel can be through whether effective and bowl cover 102 lid of active position detection module 12 closes effectively these two-fold detection and finally judges whether the bowl cover covers and arranges the cup and ensure that the reliability that detects is high, for example again, can not appear under the condition of output OUT and module earthing terminal GND short circuit, also can not appear under the condition of power end VCC and module earthing terminal GND short circuit, still judge bowl cover 102 with arrange the condition that cup 101 lid closed.
