EXAMPLE III
The embodiment provides an embodiment for measuring the rotating speed of the water pump by using a Hall signal on the basis of the first embodiment.
In an exemplary embodiment of the present application, as shown in fig. 3, the rotation speed detecting unit 4 may include: a detection circuit board 43, a hall element 44 and a magnetic element 45 (such as a magnet) provided on the detection circuit board 43;

the detection circuit board 43 may be disposed on the water pump housing 21, and the magnetic element 45 may approach the hall element 44 during the rotation process, so that the output signal of the hall element 44 changes.
In the exemplary embodiment of the present application, during the rotation of the magnetic element 45, when the magnetic element 45 approaches the hall element 44, the hall element 44 sends out a third signal, and when the magnetic element 45 approaches the hall element 44, the hall element 44 sends out a fourth signal, so as to output a continuous waveform signal during the rotation of the magnetic element 45; the waveform signal comprises a square wave signal;

In an exemplary embodiment of the present application, a detection circuit board 43 may be installed on the upper portion of the water pump 2, a hall element 44 may be provided on the circuit board 43, and a mechanism with a magnet may be installed on the exposed portion of the motor shaft 23.

Example four
The embodiment is based on the first embodiment, and provides an embodiment for controlling the water inflow through the rotation number.
In an exemplary embodiment of the present application, the water pump 2 may be a diaphragm pump;
the rotating speed detection unit 4 detects the number of rotating turns of the diaphragm pump;
and the main control unit 5 calculates the rotating speed of the diaphragm pump according to the number of rotating turns and calculates the current total water inflow amount of the diaphragm pump according to the number of rotating turns and the water inflow amount of the diaphragm pump rotating a turn.
In the exemplary embodiment of the application, because the diaphragm chamber of the diaphragm pump has a good structural consistency, the water inflow which can be achieved by one rotation of the diaphragm pump is certain, and the batch difference is relatively small compared with the rotating speed of the motor. Through the record to the water pump number of turns, can realize the control to the inflow. For example, when the required water inflow is L, the required number of turns N is L/b, and b is the water inflow of one turn of the water pump. And the MCU stops the water pump when recognizing that the number of the rotation turns is N, namely the water amount pumped into the crushing cup (namely the cup body) is L.
In the exemplary embodiment of the application, the water inflow can be controlled while no water is detected by detecting the single variable of the rotating speed, and the MCU only needs to use one port, so that the occupied resources are less.
EXAMPLE five
This embodiment provides an embodiment of detecting the total period of the plurality of square wave signals to determine whether there is no water based on the second or third embodiment.
In an exemplary embodiment of the present application, the main control unit may determine whether the water tank is empty according to a total period of the detected plurality of waveform signals; the waveform signal includes: a square wave signal.
In the exemplary embodiment of the present application, as shown in fig. 4, when the rotation speed of the water pump 2 is N1, the water pump 2 pumps water, the generated square wave signal is T1 ═ 1/2N1, the rotation speed of the motor during idle pumping is N2, the generated square wave signal is T2 ═ 1/2N2, and since N2> N1, T2< T1. Because the rotating speed is high, the difference between T2 and T1 is in millisecond level, and the deviation is small, the scheme of the embodiment judges the time of a plurality of square waves, for example 100 square waves, the pulse width time difference during water pumping and air pumping is increased, and the detection accuracy is improved.
In the exemplary embodiment of the application, the time sum of a plurality of pulse widths is judged, so that the detection accuracy is improved, and the misjudgment is avoided.
EXAMPLE six
On the basis of the second embodiment, the second embodiment is provided for collecting the number of square waves in a certain time and judging whether the infrared transceiving integrated pipe and/or the blocking piece are/is in fault.
In an exemplary embodiment of the present application, the main control unit 5 detects the pulse number of the waveform signal within a preset time period, and determines that the infrared transceiving integrated tube 41 and/or the blocking piece 42 is/are faulty when the detected pulse number is smaller than a preset number threshold.
In an exemplary embodiment of the application, the MCU may collect the number of pulses within 1s, and when the number n of pulses within 1s is detected to be less than M/4, it is determined that the infrared detection module or the baffle plate is abnormal, where M is the total number of pulses generated by the rotation speed of the water pump within 1s, and M is a positive integer.
In the exemplary embodiment of the present application, when the infrared module is out of order or the blocking plate is out of order, the waveform of the output port is reduced or no waveform is output, and at this time, the water inlet control and the water amount detection cannot be continued, and the abnormality can be identified by detecting the number of pulses per second.
In the exemplary embodiment of the application, the alarm processing can be performed after continuous detection for multiple times or a certain time duration, for example, 5s, so that the influence of sudden foreign matters or interference is avoided, and the judgment reliability is higher.
EXAMPLE seven
The embodiment provides an embodiment of controlling the working mode of the water pump along with time after water shortage on the basis of any embodiment.
In an exemplary embodiment of the application, after the main control unit determines that the water tank is lack of water, the main control unit controls a subsequent working mode of the water pump according to the current working time of the water pump.
In an exemplary embodiment of the present application, the controlling, by the main control unit, the subsequent operation mode of the water pump according to the current operating time of the water pump may include:
when the working time length is less than a preset first time length threshold value, controlling the water pump to continue working;
when the working time length is greater than or equal to the first time length threshold value and less than the second time length threshold value, controlling the water pump to continue working for the first time length and then stopping working for the second time length;
and when the working time length is greater than or equal to the second time length threshold value, controlling the water pump to stop working.
In the exemplary embodiment of the present application, the detection that the water tank is not water and the recovery after the water is added by the user in the current scheme both need the water pump 2 to work. The water shortage mainly has two conditions 1. the user starts the function without adding water; 2. the water amount is not enough in the pulping process. The situation 1 needs to be detected and recovered quickly, the time from alarming to water adding of a user in the situation two is possibly long, and the water pump 2 works all the time to cause the temperature rise of a water pump motor to be high. The scheme of the embodiment can set the working mode of the water pump after water shortage as follows: and the water pump works all the time within 30s, after 30s, the water pump works for 5s and stops working for 5s, and after 30 minutes, the water pump does not work any more and an abnormal alarm is given.
In the exemplary embodiment of the application, the user sees that in time add water to water tank 1 after the suggestion of lack of water, and water pump 2 works always and can detect immediately that there is water thereby resume the manufacturing process. When the abnormity is not processed in time, the working time of the water pump 2 can be reduced through the interval work of the water pump 2, and the service life of the water pump 2 is prolonged. The soybean milk is not continuously made after 30 minutes, so that the problem of soybean milk overflow caused by reheating the soybean milk (such as soybean milk) after cooling is avoided.
Example eight
This embodiment provides an embodiment in which the accuracy of the detection of the water-short and water-presence states is improved by continuous multiple judgments, on the basis of any of the above embodiments.

When the pulse width of 3 continuous detection periods is larger than or equal to the threshold value T, water is confirmed at the moment. The rotating speed of the water pump is about 0.7N when the water pump is loaded, and N is the no-load rotating speed of the water pump; in the idle state, the width of 100 square waves is T1-100/2N, and the width of 100 square waves is T2-100/1.4N, for reliable detection, the threshold T may be set to 100/1.7N, and the idle speed of the water pump used in the present embodiment may be 250r/s, that is, the threshold is 235 ms.
