Aerated shower head structure
An aerated shower head structure has a body, a stationary disc, a water distributor and a pressing disc sequentially assembled. The stationary disc has an air inlet hole and a water inlet hole both formed through the stationary disc and communicating with a water inlet of the body. The water distributor and the pressing disc are combined and rotatably mounted under the stationary disc. The water distributor has an air compartment and a water compartment separately formed in a bottom of the water distributor, and has an air channel selectively communicating with the air compartment and multiple water orifices selectively communicating with the water compartment. The pressing disc has an air outlet hole communicating with the air compartment, a water outlet hole communicating with the water compartment, and an elongated water passage communicating with the air outlet hole and the water outlet hole and constitute a water outflow path.
1. An aerated shower head structure, comprising:
a body having a water inlet adapted to connect to a water source;
a stationary disc securely mounted inside the body and having:
a chamber defined between the stationary disc and the body;
at least one air inlet hole formed through the stationary disc; and
at least one water inlet hole formed through the stationary disc and communicating with the water inlet of the body;
a water distributor mounted inside the body and on a bottom of the stationary disc and having:
at least one air compartment and at least one water compartment formed in a bottom of the water distributor, and spaced apart from each other;
at least one air channel formed in a top of the water distributor, each of the at least one air channel selectively communicating with a corresponding air inlet hole and a corresponding air compartment of the water distributor; and
multiple water orifices formed through the water distributor and circularly arranged on the top of the water distributor, each water orifice communicating with a corresponding water inlet hole and a corresponding water compartment;
a pressing disc combined with the water distributor to be rotatably and hermetically mounted on a bottom of the stationary disc, located under the water distributor, and having:
at least one air outlet hole formed through the pressing disc and respectively communicating with the at least one air compartment of the water distributor;
at least one water outlet hole formed in a top of the pressing disc and respectively communicating with the at least one water compartment of the water distributor; and
at least one elongated water passage formed in a bottom of the pressing disc, and respectively communicating with the at least one air outlet hole and the at least one water outlet hole; and
a water outflow assembly mounted on a bottom of the pressing disc;
wherein
the chamber inside the stationary disc and a gap defined between an inner sidewall of the body and each of the stationary disc, the water distributor, and the pressing disc constitute an air inflow path; and
the at least one elongated water passage of the pressing disc communicates with the water outflow assembly to constitute a water outflow path.
2. The aerated shower head structure as claimed in claim 1 , wherein each of the at least one elongated water passage has a first water chamber and a second water chamber sequentially arranged in a direction of water flow inside the elongated water passage, and an inner diameter of the second water chamber is greater than an inner diameter of the first water chamber.
3. The aerated shower head structure as claimed in claim 1 , wherein each of the at least one elongated water passage has a water exit communicating with a second water chamber, and a distance from the water exit to a corresponding air outlet hole of the pressing disc is four times above a distance from the corresponding air outlet hole to a corresponding water outlet hole of the pressing disc.
4. The aerated shower head structure as claimed in claim 1 , wherein the body has a stopper formed on a bottom surface of the body, the pressing disc has multiple limit bosses formed on the pressing disc, and each limit boss is selectively aligned with the stopper of the body.
