Abstract

A faucet assembly includes a faucet body defining a hot water inlet, a cold water inlet and at least one water outlet; a valve cartridge detachably received in the faucet body, the valve cartridge defines a mixing chamber and the hot water from the hot water inlet and the cold water from the cold water inlet is mixed in the mixing chamber and flows out via the water outlet; and a valve plate detachably assembled to the faucet body. The faucet body is provided with a hot water pipe connecting the hot water inlet and the mixing chamber. The hot water pipe is formed with a hot water stop valve assembly detachably assembled thereto. The faucet body is provided with a cold water pipe connecting the cold water inlet and the mixing chamber. The cold water pipe is formed with a cold water stop valve assembly detachably assembled thereto.

Claims

1. A faucet assembly, comprising:

a faucet body defining a hot water inlet, a cold water inlet and at least one water outlet;

a valve cartridge having sealing and temperature control function detachably received in the faucet body, the valve cartridge defines a mixing chamber and the hot water from the hot water inlet and the cold water from the cold water inlet is mixed in the mixing chamber and flows out via the at least one water outlet; and

a valve plate detachably assembled to the faucet body;

wherein the faucet body is provided with a hot water pipe connecting the hot water inlet and the mixing chamber, the hot water pipe is formed with a hot water stop valve assembly detachably assembled thereto, the hot water stop valve assembly comprises a hot water stop valve body, a stop valve pole and a one-way valve, and the hot water stop valve body, the stop valve pole and the one-way valve are assembled before being mounted to the faucet body from a side of the faucet body; and

the faucet body is provided with a cold water pipe connecting the cold water inlet and the mixing chamber, the cold water pipe is formed with a cold water stop valve assembly detachably assembled thereto, the cold water stop valve assembly comprises a cold water stop valve body, a stop valve pole and a one-way valve, and the cold water stop valve body, the stop valve pole and the one-way valve are assembled before being amounted to the faucet body from the side of the faucet body.

2. The faucet assembly of claim 1, wherein the hot water stop valve body defines a hot water hole corresponding to the one-way valve, and the hot water flows into the hot water valve body from the hot water inlet flows into the mixing chamber via the hot water hole;

the cold water stop valve body defines a cold water hole corresponding to the one-way valve, and the cold water flows into the cold water valve body from the cold water inlet flows into the mixing chamber via the cold water hole.

3. The faucet assembly of claim 2, wherein the hot water stop valve body comprises a first positioning step for positioning the one-way valve and the cold water stop valve body defines a second positioning step for positioning the one-way valve.

4. The faucet assembly of claim 2, wherein a first filter is seated at the hot water hole connecting the hot water stop valve body and the mixing chamber, and a second filter is seated at the cold water hole connecting the cold water stop valve body and the mixing chamber.

5. The faucet assembly of claim 1, wherein a first sealing ring is seated between the hot water stop valve body and the faucet body, a second sealing ring is seated between the cold water stop valve body and the faucet body.

6. The faucet assembly of claim 1, wherein the valve cartridge is an ordinary thermostatic valve, a thermostatic valve having pressure balance function, or a thermostatic valve having closing function.

7. The faucet assembly of claim 1, wherein the at least one water outlet of the faucet body is formed with a two water change valve spool or a three water change valve spool.
