The present invention is a lotion pump structure, and the lotion pump structure includes a piston cylinder, shut-off valve, locking ring, pump, activating tube, piston and resilient component. A first ring groove and a second ring groove are on the tapered section of the activating tube of the piston cylinder, so that the protruding ring at the top of the inner ring wall of the piston can be connected to the first ring groove. The bottom edge of the inner ring wall connects the second ring groove. The sealing effect is increased when the piston is sliding up and down, and the drawing effect on the lotion is increased. The piston is supported better to prevent the piston from being bent out of shape, further extending the working life span of the piston.
