A lotion pump, comprising:
- a bottle body;
- a pump body extending into the bottle body, wherein:
- the pump body is provided with a pump chamber,
- the pump body is connected with a bottle-locking cap used for fixing the pump body to the bottle body,
- the pump chamber is internally provided with a pumping assembly capable of moving up and down in the pump chamber to pump lotion in the bottle body upwards,
- the pump chamber is provided, at the lower end thereof, with a one-way valve only for discharging the lotion in the bottle body upwards during the action of the pumping assembly,
