Automobile wiper nozzle usually consists of the following main components:

1. Nozzle head: The nozzle head is the core component of the wiper nozzle, which usually includes one or more small holes for spraying cleaning liquid (such as wiper fluid or clean water) onto the windshield surface. The design of nozzle head affects the uniformity and stability of water spraying.

2. Nozzle shell: The nozzle shell is the shell part of the nozzle, which is used to fix and protect the nozzle head. The nozzle housing is usually connected with the fixing device on the wiper arm or windshield to ensure that the nozzle is firmly installed on the vehicle.

3. Connecting pipeline: The connecting pipeline is the pipeline that connects the wiper nozzle with the wiper liquid tank or water spraying system on the vehicle. By connecting the pipeline, the cleaning liquid can be smoothly transported from the tank to the nozzle head, and the water spraying function is realized.

4. Sprinkler system: Sprinkler system includes components such as water pump, pipeline and water nozzle, which is the core part of the whole sprinkler system. The water spraying system sprays cleaning liquid on the windshield by operating the switch or button to clean dirt and keep the driver's vision clear.

5. Adjusting device (optional): Some wiper nozzles are also equipped with adjusting devices that can adjust the spray angle or spray intensity, which can be adjusted as needed to adapt to different driving environments and needs.

To sum up, the main components of automobile wiper nozzle include nozzle head, nozzle shell, connecting pipeline, water spraying system and optional regulating device, etc. These components work together to realize the spraying and cleaning functions of cleaning liquid, ensure the driver's clear vision and improve driving safety.
