and step S100, acquiring a cleaning instruction.
The cleaning instruction can be manually input by manpower, or the controller automatically acquires the cleaning instruction after the controller detects that the adding task of the additive adding device is finished.
Step S200 is to control the cleaning liquid supply line to start supplying the cleaning liquid to the head module 300 and to control the driving module to drive the ejection end of the head module 300 to move in the weighing hopper 100 based on the cleaning command.

Therefore, in order to prevent the acidic or alkaline cleaning liquid from corroding the inner wall of the weighing hopper 100, the cleaning control method further includes the steps of:

Then, the first switch device between the outlet of the liquid storage tank 220 for storing water and the inlet of the cleaning pump 210 is controlled to be switched on, at this time, the cleaning pump 210 conveys the water in the liquid storage tank 220 to the spray head assembly 300, the inner wall of the weighing hopper 100 is thoroughly cleaned by the water, and the residual acidic or alkaline cleaning solution is washed clean.
In addition, in the process of finally cleaning the inner wall of the measuring hopper 100 by using water, the driving assembly can also drive the spray head assembly 300 to move in the measuring hopper 100, so that the movable washing effect is realized.
In an embodiment of the present invention, after the controller controls the cleaning liquid supply line to supply the cleaning liquid to the head assembly and controls the driving assembly to drive the spraying end of the head assembly to move in the measuring hopper, the cleaning control method further includes the following steps:
and step S300, controlling the cleaning liquid supply pipeline to stop supplying the cleaning liquid to the spray head assembly, and controlling the second switch device to be conducted.
After the cleaning operation is completed, the controller controls the cleaning pump 210 and the corresponding first solenoid valve 230 on the cleaning liquid supply line to close, so that the cleaning liquid supply line stops supplying cleaning liquid to the nozzle assembly 300.
Then, the controller controls the second switch device arranged between the nozzle assembly 300 and the gas supply device 510 to be conducted, or controls the second electromagnetic valve 520 to be conducted, so that the gas in the gas supply device 510 is sprayed to the inner wall of the weighing hopper 100 through the nozzle assembly 300, the inner wall of the weighing hopper 100 is dried by the gas, and the inner wall of the weighing hopper is prevented from being corroded by the residual cleaning solution.
The washing control process and the drying control process will be described separately below.
And the user manually inputs a cleaning starting instruction, or the controller automatically enters a cleaning task after the additive adding task is finished.
After entering a cleaning task, a user manually inputs cleaning liquid type information or the controller calls additive type information, and the controller matches the corresponding cleaning liquid type according to the cleaning liquid type information or the called additive type information manually input by the user.

Then, the controller controls the driving assembly to drive the spraying end of the nozzle assembly 300 to move in the weighing hopper 100, so as to perform moving cleaning on the weighing hopper 100.
When the cleaning solution is an acidic cleaning solution or an alkaline cleaning solution, the controller controls the first electromagnetic valve 230 on the liquid storage tank 220 containing the cleaning solution corresponding to the type information of the cleaning solution to be powered off and closed, and then opens the first electromagnetic valve 230 on the liquid storage tank 220 containing water, so that the inner wall of the weighing hopper 100 is finally cleaned by using the water.
