Description

Technical Field

[0001] This utility model relates to the field of shower head technology, and in particular to a multi-functional spray gun shower head. Background Technology

[0002] Existing spray guns and shower heads typically have two functions: spray gun water output and shower head water output. A switch button can be used to switch between spray gun water output and shower head water output, and the shower head water output function can also be independently controlled to achieve different shower head water output modes.

[0003] However, the existing shower heads with both spray gun and shower head functions have different structures; some have complex structures such as ratchet in the water path switching device, which are prone to jamming after a period of use; others have complex water path switching structures that are prone to internal blockage, resulting in a small water spray volume after a period of use, which affects the use.
