Title: PRESSING PUMP
Abstract:
A pressing pump (1), comprising: a pressing pump body (10), the pressing pump body (10) being provided therein with a spring tube (20), while a spring (21) is accommodated in the spring tube (20); a cylinder cover (30), the cylinder cover (30) being installed on the pressing pump body (10) and comprising an inner hole (31); a pressure head (40), the pressure head (40) comprising a pressing part (41) and a rod part (42), wherein the rod part (42) fits within the inner hole (31) of the cylinder cover (30), and a lower portion of the rod part (42) fits with the spring (21) such that the spring (21) applies an upward biasing force on the pressure head (40); and a piston (50), the piston being connected to the pressure head (40) and being slidably sealed fit with an inner peripheral surface of the pressing pump body (10). The pressing pump (1) may use a spring (21) having a small size to meet large discharge requirements, thereby reducing manufacturing costs, and may further prevent a product from touching the spring (21), thus preventing adverse effects therebetween.
