When the air passage unit is in the exhausted state, the first air connecting portion 22 is in communication with the first air passing passage 211 through the air connecting path 312, the second air passing passage 212 is in communication with the air connecting opening 251 through the air exhaust path 313, the on-off portion is closed to achieve blocking, and the air in the air cavity of the massaging pool successively passes through the first air connecting portion 22, the air connecting path 312, the first air passing passage 211, the air pump 1, the second air passing passage 212, the air exhaust path 313, and the air connecting opening 251 to achieve exhausting. The inflated state and the exhausted state can refer to air passage illustrations in Embodiment 2. The air pump 1 does not need to change a direction of rotation using the structure abovementioned, as long as being controlled by the control mechanism to achieve exhausting or inflating.

[0070] In this embodiment, the control mechanism 3 has integrated to achieve inflating of the air cavity, inflating of massage bubbles, and exhausting of the air cavity to facilitate user use. However, according to needs, the control mechanism may not be provided, so that only the air cavity inflation and the massage bubbles inflation are assembled together, and the massage pool is collapsed by the natural exhaust method.

[0071] The massaging pool comprises the air passage system and a pool body. The air cavity is defined within the pool body, and the pool body comprises a first one of the two second air connecting openings. The pool body surrounds to define the pool cavity, and the pool body comprises a second one of the two second air connecting openings configured to be in communication with the pool cavity and cooperating with the pool cavity to generate the massage bubbles. The pool body comprises a second fastening structure, and the two second air connecting openings are disposed on the second fastening structure. The two first air connecting openings are synchronously respectively connected to or detached from the two second air connecting openings through the second fastening structure being connected to or detached from the first fastening structure.

Embodiment 2

[0072] Referring to FIGS. 9-12, this embodiment is similar to the embodiment 1 but has the differences described below. The switching valve 23 comprises a valve core 231 ’ configured to slide in the air passage unit, and the valve core slides to achieve switching abovementioned. Specifically, the switching valve 23 comprises the valve core 231’, the operating member 232, and the transmission gear 233. The valve core 231’ cooperates with the air passing portion 21 and the first air connecting portion 22 to switch the two first air connecting openings 221, 222 to be alternatively in communication with the air passing portion 21, and the operating member 232 and the transmission gear 233 are coaxially fixedly connected to each other and are configured to rotatably connected to the mounting seat 24. The valve core 231’ is disposed with a rack that is located outside thereof, the transmission gear engages the rack, the operating member 232 drives the transmission gear to rotate, and the valve core 231’ correspondingly slides through the transmission gear being operatively coupled to the rack. The gear fit facilitates the layout, improves the convenience of rotation, and improves the reliability of rotation.

[0073] The aforementioned embodiments are merely some embodiments of the present disclosure, and the scope of the disclosure is not limited thereto. Thus, it is intended that the present disclosure cover any modifications and variations of the presently presented embodiments provided they are made without departing from the appended claims and the specification of the present disclosure.

[0074] The various embodiments of an air passage system disclosed herein are useable with spa 1002 (also known as a massaging pool) shown in FIGS. 13 and 14. Massaging pool 1002 comprises an inflatable structure having air cavity 1004 into which air is pumped by one of the air passage systems of the present disclosure. Massaging pool 1002 also includes pool cavity 1006 defined by the pool body, which includes upstanding wall 1008 surrounding pool cavity 1006. Upstanding wall 1008 is formed when massaging pool 1002 is inflated. Pool cavity 1006 accommodates water and occupants.

[0075] Referring to FIG. 14, massaging pool 1002 connects to any of the air passage systems disclosed herein, with first fastening structure 223 selectively secured to second fastening structure 1010. In exemplary embodiments, second fastening structure 1010 defines a threaded connector matable with first fastening structure 223 to seal first air connecting openings 221, 222 to second air connecting openings 1012 for fluid communication therebetween. Specifically, first air connecting opening 221 is placed in fluid communication with air cavity 1004 via a first one of second air connecting openings 1012 to selectively inflate and deflate massaging pool 1002, as described above, and second air connecting opening 222 is placed in fluid communication with pool cavity 1006 via a second one of second air connecting openings 1012 to generate massaging bubbles in a quantity of water contained in pool cavity 1006, when desired. Second air connecting openings 1012 are disposed on second fastening structure 1010 in similar fashion to first air connecting openings 221, 222 being disposed on first fastening structure 223, as described above. Second air connecting openings 1012 are disposed on second fastening structure 1010 so as to enable the two first air connecting openings 221, 222 to be synchronously connected to or detached from second air connecting openings 1012 through the first fastening structure 223 being connected to or detached from the second fastening structure 1010 and thereby connected to or detached from the massaging pool.
