Integrated waterway assembly of a reverse osmosis water filtration device
An integrated waterway assembly of a reverse osmosis (RO) water filtration device includes a main body, a shut off valve, a mounting shelf, a top cover, a bottom cover and a fixing ring. Water to be filtered sequentially goes through a water inlet, a shut off valve, a RO cartridge joint and a check valve, and a filtered water outlet on the main body to get the water filtered. The RO cartridge joint on a bottom portion of the main body is connected with a RO cartridge, and water enters the RO cartridge and further flows through the RO cartridge joint to get the water filtered. Given the foregoing structure, the water filtration device is structurally compact and integrated and has less water leakage.
1. An integrated waterway assembly of a reverse osmosis (RO) water filtration device comprising:
a main body having:
two lateral sides;
a water inlet formed in one of the lateral sides of the main body for water to enter the main body;
a shut off valve formed inside a front portion of the main body, communicating with the water inlet, and having a shut off valve outlet;
a check valve formed in the front portion of the main body, located next to the shut off valve, and having a check valve outlet;
a stored water outlet formed in the other lateral side of the main body for water filtered by the water filtration device to exit therefrom;
a filtered water outlet formed beside of the stored water outlet for water filtered by the water filtration device to exit therefrom;
a waste water outlet formed beside of the filtered water outlet for waste water generated by the water filtration device to exit therefrom;
a RO cartridge joint formed on a bottom portion of the main body, connected with a RO cartridge, and having a RO water inlet and a RO water outlet and a RO waste water outlet;
a first chamber formed into the main body, wherein the water inlet communicates with the shut off valve through the first chamber;
a second chamber formed into the main body, wherein the shut off valve outlet communicates with the RO water inlet through the second chamber;
a third chamber formed into the main body, wherein the RO water outlet communicates with the check valve through the third chamber;
a fourth chamber formed into the main body, wherein the check valve outlet communicates with the stored water outlet and the filtered water outlet through the fourth chamber; and
a fifth chamber formed into the main body, wherein the waste water outlet communicates with the RO waste water outlet through the fifth chamber.
2. The integrated waterway assembly of water filtration device as claimed in claim 1 , further comprising:
a mounting shelf, wherein the main body is mounted inside the mounting shelf;
a top cover formed on a top of the mounting shelf;
a bottom cover mounted on a bottom of the mounting shelf, and having a hole centrally formed through the bottom cover.
3. The integrated waterway assembly of water filtration device as claimed in claim 1 , wherein the shut off valve has a lid connected with the main body and connected with the check valve through a connection bar.
4. The integrated waterway assembly of water filtration device as claimed in claim 3 , wherein the connection bar has a water channel communicating with the check valve outlet and the fourth chamber.
5. The integrated waterway assembly of water filtration device as claimed in claim 1 , wherein the main body has four quick couplers respectively mounted into the water inlet, the stored water outlet, the filtered water outlet and the waste water outlet.
6. The integrated waterway assembly of water filtration device as claimed in claim 1 , further comprising a fixing ring mounted through the hole of the bottom cover and mounted around the RO cartridge joint to fasten the RO cartridge joint.
