  The present invention relates to a spray head, and more particularly, to a structure of a spray head provided in a container containing a liquid such as an emulsion or a perfume.

  As shown in FIG. 1, the conventional spray head includes a pressing body 11, a sleeve 12, a pump pipe 13, a pump pipe sleeve 14, a base pipe 15, an elastic body 16, a metal ball 17, and a cylinder body 18. The pump pipe 13 passes through a through hole 121 drilled at an appropriate location of the sleeve 12, and the upper part of the pump pipe 13 is connected to the pressing body 11. A base tube 15 is connected to the opening at the lower end of the pump tube 13. In the base tube 15, holes 151 for allowing milky milk, perfume, etc. to enter the base tube 15 are formed at opposite positions on the outer periphery. The base tube 15 is inserted into the pump tube sleeve 14 so that the hole 151 is shielded. The bottom of the base tube 15 is formed into a disk shape that does not open.

  The metal ball 17 is accommodated in the cylinder body 18. One opening end of the cylinder body 18 is formed so that the diameter gradually decreases from the opening end, and the other opening diameter of the cylinder body 18 is made narrower than the diameter of the metal sphere 17. Next, the elastic body 16 is stored so as to be positioned on the metal ball 17. Finally, the cylinder body 18 is inserted into the sleeve 12, the outer peripheral edge of one open end of the cylinder body 18 is connected to the bottom edge of the through hole 121 of the sleeve 12, and one end of the elastic body 16 is formed at the bottom of the base tube 15. The suction pipe 19 is connected to the lower end of the cylinder body 18.
