First, as a decorative part, it is located at the outermost part of the dispenser and is the main part of the hand contact, so with different decorative designs and shapes, different aesthetic effects can be formed. Another function is that the inner circular surface is the sliding fit of the nut, and the outer sleeve is inserted into the nut and the cylinder is fastened by the inner extending leg.

Each time the screw is pressed or pressed, the large piston moves downward in the cylinder, thereby reducing the volume of the cylinder to realize the function of discharging air or contents. Unscrewing the nut or releasing the push button will cause the large piston to move upwards, thereby increasing the capacity of the cylinder and achieving the function of sucking in contents.
  • the large piston is pressed under the nut, and pressing the button moves the large piston downward through the nut.

  • Spring 6 The material can be made of stainless steel. Its function is to provide power. Press the button or tighten the nut, and the spring is pressed and contracted. Release the button or unscrew the nut. Under the action of the spring restoring force, the large piston moves up. The small piston moves down, thereby increasing the volume of the cylinder and sucking in the contents. The spring is pinched between the large piston and the small piston and is the main component that provides power.
  • Gasket 7 This part is made of plastic and is a part used to seal the leak of the bottle mouth.
  • Pipette 8 This part can be made of plastic or glass.
  • the main function is to store the liquid contents taken by the dispenser and is the most important brake function. Because the present invention is such that when the member is in contact with the bottom of the bottle, the liquid suction nozzle is stopped at the bottom of the container, and does not leave, nor can it be excessively contacted. Therefore, it is necessary to make the component retreat a short distance when it contacts the bottom of the bottle, and push the small piston upward compression spring to release the downward pressure.
  • Small piston 9 This part is made of plastic and placed inside a large piston. This part provides two functions. First, the small piston wraps the metal spring to keep the spring out of contact with the contents. Second, the small piston moves in the opposite direction to the large piston, and the contact with the pipette provides the most important function of the dispenser, which is the action of the pipette returning.
  • the reason why the invention can absorb the contents of the bottom of the bottle is because the liquid suction pipe can contact the bottom of the bottle without bending and breaking, so the liquid suction pipe has the function of being able to retract, when the liquid suction pipe contacts the bottom of the bottle After the retraction, there must be a returning transmission member of the pipette, and the power of the returning position is transmitted to the spring through the small piston.
  • Capacitor 10 This part is made of plastic and is the main component of the present invention. All the functional parts are installed in the tank first, locked with a fixed lock, and then formed with a nut and a jacket. The gasket is placed under the tank to form an important structural component for sealing the product.
  • the volume cylinder is also a component that determines the amount of pressure to be pressed.
  • the volume of the large piston and the volume of the cylinder is constructed as the discharge amount per pressing, which is the basic function of the dropper.
  • the cylinder is also a component that is engaged with the jacket.
  • the cylinder of the cylinder is fastened to the structure, so that when the invention is screwed to the bottle neck, the button will descend on its own to reach the air first, and when the nut is unscrewed, the dispenser will Automatically inhale contents.
  • the structure in which the cylinder seal is inserted into the bottle neck is another characteristic structure.
  • the gasket of the tank is the first seal leakage prevention design, and the cylinder seal is inserted into the bottle mouth to form a second intervening leakproof, so that the invention has more Strong leak-proof ability.
