Latex collecting device with flow guiding and filtering functions

According to the latex collecting device with the flow guiding and filtering functions, when latex is collected, the latex sequentially passes through the liquid collecting pipe, the first communicating pipe and the liquid inlet pipe to flow into the lower cavity of the collecting barrel and is filtered at the position of the filter screen of the first communicating pipe, and in the process, the flow guiding and filtering functions are achieved. The air charging and discharging mechanism is used for extracting air at the upper cavity and discharging the air through the second communicating pipe and the blow-off pipe, the piston moves upwards, the negative pressure generated by the lower cavity guides the liquid inlet process, at the moment, liquid enters the first communicating pipe, the second communicating pipe exhausts air, and the filter screen at the second communicating pipe is subjected to backwashing in the exhausting process; the liquid inlet working state and the exhaust working state between the fi
