Abstract

A liquid injection pump includes cover 2 for matching the opening of the container^s neck fastened to the container by the cover. In addition, the pump body 3 is formed with the internal sucking valve 9 hanging downward to the bottom of container. The ring piston 27 inside pump 3 can be installed with rod 28 over the bottom of the external perimeter that can move up and down. On the top of the rod the top of the cover is installed with nozzle 29 and pressing head 30. The injection valve 31 is installed inside of the top of the rod 28, and the up-and-down moving part 4 is composed of the rod and pressing head along with the spiral spring 38 always pressing to the top portion. By means of the up-and-down motion from the up-and-down moving part 4, the liquid in container can go through valve 9 sucked into pump body 3. Meanwhile, the liquid injection pump that injects in the fluid from nozzle through valve 31 is characterized by that the multiple rib plates 10 extruded from the perimetric direction of pump body and located in the bottom of the spiral spring 38. The liquid flow paths 50 are installed in the in and out sides through the down portion of the spiral spring and the attached concaved parts 11 provided on the rib plates for keep the bottom of the spiral spring.
