In this embodiment, when the motor of the stirring device is also operated, if the operation of the air pump device is continuously controlled with a large power, the slurry will overflow, so when the motor is not operated at full power, the power of the air pump device should be smaller than the power when the motor is not operated at full power, so as to avoid the slurry overflow caused by the excessive power.
Further, step S22 specifically includes: and when the slurry temperature is in the preset temperature interval and the motor runs in the non-full-power state, if the first power corresponding to the slurry temperature is smaller than the preset power, controlling the air pump device to stop running.

assuming that the power range of the motor used by the air pump device is 1-10W, the power is adjusted by adjusting the PWM duty ratio when air is pumped.
When the temperature of the slurry (such as the real-time temperature of the slurry) is in the range of 40-90 ℃ and the motor driving the stirring device stops working, the air pump device is started, the higher the temperature of the slurry is, the lower the power of the air pump device is, the lower the flow rate of the gas pumped into the machine body is, preferably, the power adjusting range of the air pump device is 1-5W, and the control range of the flow rate of the air pump is 10-100L/min; when the temperature of the slurry is in the range of 40-90 ℃ and the motor does not work at full power, the power of the air pump device is automatically reduced by a preset value, such as 2W (if the power of the air pump device is less than or equal to 2W before the motor is started, the air pump device stops running after the motor is started); when the temperature of the slurry is out of the range of 40-90 ℃ and/or the motor works at full power, the air pump device is stopped. In a preferred embodiment, the specific control process of the air pump device is shown in table 1:
TABLE 1
As shown in table 1, when the temperature of the slurry is less than 40 ℃ or greater than 90 ℃, the air pump device stops working no matter what state the motor rotation speed is; when the motor runs at full power, the air pump device stops working no matter what temperature the slurry is; when the temperature of the slurry is in the range of 40-50 ℃, if the motor stops running, the power of the air pump device is 5W, and if the motor does not run at full power, the power of the air pump device is 3W; when the temperature of the slurry is within the range of 50-60 ℃, if the motor stops running, the power of the air pump device is 4W, and if the motor does not run at full power, the power of the air pump device is 2W; when the temperature of the slurry is in the range of 60-70 ℃, if the motor stops running, the power of the air pump device is 3W, and if the motor does not run at full power, the power of the air pump device is 1W; when the temperature of the slurry is in the range of 70-80 ℃, if the motor stops running, the power of the air pump device is 2W, and if the motor does not run at full power, the air pump device stops running; when the temperature of the slurry is in the range of 80-90 ℃, if the motor stops operating, the power of the air pump device is 1W, and if the motor does not operate at full power, the air pump device stops operating.
In the above embodiments, the technical solutions of the present invention are described in detail by taking examples of different temperature intervals corresponding to different powers of the air pump device, where the numerical values are merely preferred examples, and are not specifically limited, and in practical applications, the corresponding numerical values may be adjusted according to practical situations. In addition, in other embodiments of the present invention, the power of the air pump device may be linearly related to the slurry temperature, and after the slurry temperature is detected, the operation power of the air pump device is determined according to the linear relationship (if the motor for driving the stirring device is also operated, the predetermined value is decreased based on the operation power determined according to the linear relationship).

Particularly, the temperature of the slurry and the rotating speed of the motor of the stirring device have certain influence on the overflow of the slurry, for example, when the temperature of the slurry is high and the rotating speed of the motor of the stirring device is high, the slurry is easily caused to overflow, so that the power of the air pump device is controlled according to the rotating speed of the motor and the temperature of the slurry, and more gas can be pumped into the machine body of the soybean milk machine on the premise of ensuring that the slurry is not overflowed, so that the oxidation of the slurry is promoted.
Further, the control unit 304 is specifically configured to: and when the temperature of the slurry is in a preset temperature interval, if the motor is in a stop state, controlling the air pump device to operate at a first power in an inverse correlation relation with the temperature of the slurry.
In this embodiment, when the temperature of the slurry is within the predetermined temperature range and the motor is in the stop state, the power of the air pump device is controlled to have an inverse correlation with the temperature of the slurry, so that when the temperature of the slurry is low, the air pump device can be controlled to operate at a high power, and further more air can be pumped into the machine body, thereby promoting the thermal volatilization loss of the beany flavor substances and promoting the oxidation of the slurry to ensure the production of the beany flavor substances, and simultaneously, when the temperature of the slurry is high, the air pump device can be controlled to operate at a low power, and the overflow of the slurry caused by the high power of the air pump device is avoided.
Further, the control unit 304 is specifically further configured to: when the temperature of the slurry is in the preset temperature interval, if the motor runs in a non-full-power state, controlling the air pump device to run at a second power which is in an inverse correlation relation with the temperature of the slurry; wherein, under the condition that the temperature of the slurry is constant, the second power is the difference between the first power and the preset power.
In this embodiment, when the motor of the stirring device is also operated, if the operation of the air pump device is continuously controlled with a large power, the slurry will overflow, so when the motor is not operated at full power, the power of the air pump device should be smaller than the power when the motor is not operated at full power, so as to avoid the slurry overflow caused by the excessive power.
Further, the control unit 304 is specifically further configured to: and when the slurry temperature is in the preset temperature interval and the motor runs in the non-full-power state, if the first power corresponding to the slurry temperature is smaller than the preset power, controlling the air pump device to stop running.
In this embodiment, since the power of the air pump device when the motor is not operated at full power is calculated by the difference between the first power and the predetermined power, if the first power is less than the predetermined power, the air pump device may be directly controlled to stop operating.
According to an embodiment of the present invention, the control unit 304 is specifically configured to: and when the motor is in a full-power operation state and/or the slurry temperature is out of a preset temperature range, controlling the air pump device to stop operating.
In this embodiment, when the slurry temperature is outside the predetermined temperature interval, it is indicated that the slurry temperature may be lower or higher. When the temperature of the soybean milk is lower, the oxidation process of the soybean milk is slow, and the influence on the improvement of the flavor of the soybean milk is not large even if the air pump device works, so that the air pump device can be controlled to stop working, and useless work is avoided; when the temperature of the slurry is higher, the slurry is easy to overflow, so that the air pump device can be controlled to stop working. In addition, when the motor runs at full power, the rotating speed of the stirring device is high, and at the moment, the slurry is easy to overflow, so that the air pump device can be controlled to stop working.
