The variable density body 2-2 is slidingly installed on the inner wall of the pool body 2-1, and a variable cavity 2-3 is formed between the variable density body 2-2 and the inner wall of the pool body 2-1. The bottom end of the water outlet spray pipe 3 is installed on the bottom of the variable density body 2-2, and the top end of the water outlet spray pipe 3 extends to the garden ground for spraying and watering operations.

Among them, the most important structural setting is the variable density body 2-2. In this embodiment, the variable density body 2-2 is a block that changes its own density based on the internal inflatable principle.
