Abstract
The present invention provides a nozzle (201), which comprises a nozzle passage (512) and a fluid passage (511), wherein the nozzle passage has an airflow inlet (515) and an airflow outlet (516). The fluid passage has a fluid passage inlet (518) and a fluid passage outlet (514), wherein the fluid passage inlet communicates with a fluid source so that a fluid can enter the fluid passage, and the fluid passage outlet communicates with the nozzle passage so that the fluid can enter the nozzle passage, and the airflow exerted from the airflow inlet can press the fluid in the nozzle passage out of the airflow outlet. The nozzle provided by the present application can distribute a small volume of a viscous fluid and is not apt to get blocked.

1-15. (canceled)
A nozzle, comprising:
- a nozzle passage, the nozzle passage having an airflow inlet and an airflow outlet, and
- a fluid passage, the fluid passage having a fluid passage inlet and a fluid passage outlet, wherein the fluid passage inlet communicates with a fluid source so that a fluid can enter the fluid passage, and the fluid passage outlet communicates with the nozzle passage so that the fluid can enter the nozzle passage,
- wherein the airflow exerted from the airflow inlet can press the fluid in the nozzle passage out of the airflow outlet.
A nozzle assembly, comprising:
- a casing, a chamber being arranged in the casing,
- a sleeve, the sleeve being arranged in the chamber of the casing, the inner wall of the sleeve defining a piston passage, and a fluid chamber being arranged between the outer wall of the sleeve and the inner wall of the casing,
- a nozzle, the nozzle being arranged in the chamber of the casing and being arranged below the sleeve, the nozzle comprising:
- a nozzle passage, the nozzle passage having an airflow inlet and an airflow outlet,
- a fluid passage, the fluid passage having a fluid passage inlet and a fluid passage outlet, wherein the fluid passage inlet communicates with the fluid chamber so that a fluid in the fluid chamber can enter the fluid passage, and the fluid passage outlet communicates with the nozzle passage so that the fluid can enter the nozzle passage,
- a piston chamber, the piston chamber communicating with the airflow inlet of the nozzle passage and communicating with the piston passage, and
- a piston, the piston being able to move up and down in the piston passage and the piston chamber and being able to draw in and discharge air through the nozzle passage to press the fluid in the nozzle passage out of the airflow outlet of the nozzle passage.
