This avoids uneven filling or clogging caused by poor fluidity. During filling, the drive motor 19 drives the conveyor belt 16 to rotate, moving the bottle placed on top of the pallet 15 to below the filling cylinder 11.

Under negative pressure, the raw material inside the storage tank 5 is injected into the cavity 28 through the liquid inlet pipe 12. At the same time, as the piston 27 moves upward, it compresses the air inside the cavity 26, causing the compressed air to be injected into the storage tank 5 through the air return pipe 7, thereby increasing the air pressure inside the storage tank 5 and further increasing the air pressure difference between the storage tank 5 and the cavity 28, ensuring that the laundry detergent is quickly introduced into the cavity 28. Since the piston 1 23 and the piston 2 27 move synchronously, the metering sensor 25 monitors the movement stroke of the piston 2 27 in real time, thereby realizing the metering control of the piston 2 27's stroke. After the metering requirement is met, the solenoid valve 2 14 is closed and the solenoid valve 3 13 is opened. The hydraulic telescopic rod 24 drives the piston 1 23 and the piston 2 27 to move downward through the connecting rod 22. The piston 1 23 fills the bottle with the metered laundry detergent through the drain pipe.
