Abstract
A spray pump formed to atomize and apply a viscous liquid may micro-discharge the viscous liquid ranging from low to high viscosity in a quantitative manner, may miniaturize a device capable of atomizing liquids by spraying, and may shorten a spraying path to prevent changes in liquid properties and keep spraying quality constant.
Claims17
A spray pump comprising:
- a syringe in which a viscous liquid is stored;
- a valve member comprising
- a reservoir receiving the viscous liquid from the syringe and storing the same,
- a nozzle connected to a lower portion of the reservoir to discharge the viscous liquid to an outside, and
- a sheath passage extending toward an end of the nozzle to discharge a gas to spray the viscous liquid discharged from the nozzle;
- a valve rod inserted into the reservoir of the valve member so as to move forward and backward with respect to the nozzle of the valve member and discharge the viscous liquid stored in the reservoir through the nozzle;
- and
- an operation member moving the valve rod back and forth with respect to the valve member.
