Abstract
An air connection pipeline device of a massage pool may comprise a pipeline. The pipeline may be formed with a first air connection passage and a second air connection passage. The first air connection passage may have a first air inlet and a first air outlet. The first air connection passage may include a check valve located between the first air inlet and the first air outlet. The check valve may be driven to open when the air flow moves from the first air inlet to the first air outlet and close when reversely. The second air connection passage may be provided with a switch valve. The switch valve may comprise a second valve core and a second elastic body. The second valve core may slide between a closed position to close the second air connection passage and an open position to open the second air connection passage. The second elastic body may press against the second valve core. An initial state of the second valve core may be the closed position.
