The existing lotion bottle is provided with a leak proof lotion pump surrounded by the peripheral wall of a main column. The lotion pump comprises a pressing head, a lock cover, a screw thread sleeve, a body, a main column, a secondary column, a piston, glass balls, a spring and a suction pipe. The lock cover comprises an outer ring and an inner ring positioned at the inner side of the outer ring, wherein the inner ring is sleeved outside the body to prevent lotion from flowing out of the lotion bottle from a gap between the body and the lock cover due to transportation vibration and other reasons when the lotion bottle is in a closed state.
The existing lotion pump has the problem that when the lotion pump is in an open state, the body, the piston and the lock cover form a space, and lotion in the space needs to be discharged through the vent when the spring rebounds after the lotion pump is squeezed when the lotion bottle is opened because lotion enters the space through the vent or other gaps during transportation.
However, the existing lotion pump body is provided with a small number of air vents and a small opening area. When the lotion covers the air vents, the pushing force provided by the spring to the piston is not enough to offset the lotion tension and then drives the main column, the auxiliary column and the press head to move smoothly, resulting in slow rebound after pressing the press head and abnormal operation of the lotion pump.
