[0039] Part usage explanation,

[0040] Washing machine dispenser pump body: The washing machine dispenser pump body is the core part of the entire pump, which connects and contains other components, and ensures the correct flow of detergent in the pump;

[0041] Valve body: The one-way valve in the valve body is one of the key components of the pump, which ensures that the detergent can only flow in one direction, preventing backflow and leakage;

[0042] Piston: The piston is the main working component of the pump, which generates pressure through reciprocating motion to push the detergent out of the pump body;

[0043] Eccentric wheel: The eccentric wheel converts the rotary motion of the motor into the reciprocating motion of the piston, driving the pump to work;

[0044] Motor: The motor is the power source of the pump, which provides energy to drive the eccentric wheel to rotate, thereby driving the piston to move;

[0045] Outlet channel: The outlet channel is the channel through which the detergent flows out of the pump body, which is connected to the detergent dispenser to deliver the detergent into the washing machine;

[0046] Inlet channel: the inlet channel is a channel for the detergent to enter the pump body, which is connected to the detergent storage container to suck the detergent into the pump body;

[0047] The various components of the washing machine dispenser pump work in coordination to ensure that the detergent can be accurately and stably delivered into the washing machine, thereby achieving the cleaning function.
