Description:
BACKGROUND OF THE INVENTION  
       [0001]     1. Field of the Invention  
         [0002]     The current invention relates to a green nozzle, it specifically relates to a simplest component assembly where the liquid such as lotion or perfume in the container won&#39;t change its quality, through the simplest component and assembly to achieve the ejection function of lotion or perfume and enhance the economic effectiveness.  
         [0003]     2. Description of the Prior Art  
         [0004]     In the prior art nozzle  1  structure, as shown in  FIG. 1 , comprising of a pressing body  11  installed on tooth cover  12 , the upper part of tube  13  installs at and penetrates the holes  121  of tooth cover  12  in order to be connected to the pressing body  11 , the lower part of the tube  13  is installed and penetrated with a tube cover  14  to be connected to a base tube  15 , meanwhile, the correlating small holes  151  installed at both sides of the base tube  15  are just exactly covered by the tube cover  14 , meanwhile, a spring  16  is installed at the lower part of the base tube  15 , a steel ball  17  is placed at the lower part of the spring  16 , they are installed in the cylinder  18  which shrinks its hole diameter from top to the bottom, therefore, the upper edge end of the cylinder  18  is connected to the bottom edge of the slot hole  121  of the tooth cover  12 , moreover, the lower end of the cylinder  18  is connected to a straw  19 .  
         [0005]     From the above descriptions, the user first press on the pressing body  11  to let the air in the container immediately eject from the nozzle opening  111  of the pressing body  11 , in the mean time, the siphon effect will bring the liquids such as lotion or perfume from the straw  19  with the air into the cylinder body  18 , at this moment, due to the spring force of the spring  16 , the bottom of the tube base  15  will press on the steel ball  17  and the steel ball  17  will block the hole of the cylinder  18 , furthermore, make a gap between the tube base  15  and tube cover  14  and make the lotion or perfume contained in the cylinder  18  can go along the space of the gap to the small holes  151  on the two sides of the outer edges of the base tube  15  and penetrate into the base tube  15 , then through the tube  13 , the lotion or perfume will be ejected along with air out from the nozzle opening  111  of the pressing body  11 , when the pressing body  11  is let go, the liquids such as lotion or perfume remained in the cylinder  18  will then go back to the container.  
         [0006]     Continued from the above descriptions, in the prior art structure of nozzle  1 , although the function of the ejection of lotion or perfume still can be reached, since the spring  16 , steel ball  17  are made up of metallic material and are installed inside the cylinder  18 , they could cause chemical change for the lotion and perfume in the container due to the long time contact to the metallic spring  16  and steel ball  17 , which in turn could deteriorate the quality of the lotion or perfume and harm the customers, but if the chemically changed lotion or perfume are dumped away, they will cause environmental contamination due to difficulty in dilution and recycling; moreover, since the structure design of the prior art nozzle  1  has so many components, it cause an increase in the material cost, its difficulty in assembly and disassembly further reduces practical economic effectiveness.  
         [0007]     Therefore, to solve the drawback and inconvenience in the prior art nozzle, the inventor of the current invention thus developed a more practical structure for green nozzle which can have a more wide-spread use in the industry and take into account environmental issue as well.
