Description

Technical Field

[0001] The utility model relates to the technical field of massage pools, in particular to an inlet and outlet water pipe and a SPA pool comprising the inlet and outlet water pipes. Background Art

[0002] A spa pool typically includes an inflatable pool wall with inner and outer walls, and a pump body with a filter pump. The filter pump is connected to the spa pool via an inlet pipe and an outlet pipe to filter and clean the water in the spa pool. The inlet and outlet pipes of spa pools in the prior art include hoses with connectors at both ends. The flanges of the connectors are coated with PVC. The flanges of the connectors are sealed to the inner and outer walls of the spa pool via the PVC coating using high-frequency heat sealing. The inlet and outlet of the filter pump are detachably connected via an adapter. This structure of connecting the hoses to the inner and outer walls has the following drawbacks:

[0003] The reliability of the high-frequency heat-sealing between the flange of the connection, encased in PVC, and the inner and outer walls of the spa pool is poor. When the air pressure inside the inflatable pool wall is high, the seal quality may be poor, resulting in a weak connection between the flange of the connection at both ends of the hose and the inner and outer walls. This can cause leakage in the inflatable pool wall, impacting user experience. Furthermore, once the inflatable pool wall leaks, it is usually impossible to repair it, forcing the entire pool to be scrapped, resulting in a wasteful cost. Utility Model Content
