Description

BACKGROUND OF THE INVENTION

Field of the Invention

The present invention relates to a faucet detaching and replacing method, and in particular to a faucet main body fast detaching and replacing method and a faucet structure for implementing the same.

The Prior Arts

In general, faucet and faucet related components tend to be worn out or damaged after long period of use. At this time, the faucet and faucet related components have to be detached, repaired, or replaced. Also, after long period of usage, the contaminated and dirty faucet has to be detached, cleaned, and sterilized. In addition, sometimes, the faucet has to be detached and replaced to make it compatible with the setting of the room. However, in detaching a faucet, the water supply switch has to be closed, while the repairman has to crawl into a very small space in the counter under the faucet, that is rather tedious and inconvenient.
Therefore, presently, the design and performance of the faucet is not quite satisfactory, and it leaves much room for improvement.

Meanwhile, in detaching, through pressing the protrusion knob 32 inward, it is able to detach the position blocking ring 35 from the ring-shaped slot 21, in realizing fast detaching.
In an embodiment of the present invention, the push button ring 31 and the position blocking ring 35 are restricted in the lower end portion of the faucet set main body 10 through a ring-shaped lock tight block 80 having outer threads. The faucet set main body 10 is further provided with a pulling tube 11 penetrating through the faucet bottom seat 20 from top to bottom.
The application of the faucet structure is as follows:

1. Placing the gasket 70 around the assembled faucet bottom seat 20, then penetrating them through a through hole on the mesa 90 from top to bottom, then place the tight seal pad and the copper pad around the faucet bottom seat 20, while using the lock tight ring 60 to lock the faucet bottom seat 20 tightly on the mesa 90.
2. Connecting the water input hose 40 to the faucet bottom seat 20.
3. After installing the push button position blocking component 30 onto the faucet set main body 10 through using the ring-shaped lock tight block 80, installing the faucet set main body 10 onto the faucet bottom seat 20, so that the push button position blocking component 30 is fastened into the ring-shaped slot 21 of the faucet bottom seat 20; meanwhile, place the pulling tube 11 through the faucet bottom seat 20. After inserting the water input tube 12 of the faucet set main body 10 into the channel 22, connect and press it against the upper connection tube 52. Then, when the faucet set main body 10 is pressed downward, the water input tube 12 makes the piston block 51 to move downward, to achieve opening of the water channel 22.
4. When detaching the faucet set main body 10, all it has to do is to press the protrusion knob 32 inward, to make the position blocking ring 35 detach from the ring-shaped slot 21, to realize detaching the faucet set main body 10. In detaching the faucet set main body 10, the water input tube 12 is detached from the upper connection tube 52, so that the piston block 51 returns to its original position, to close the water channel 22. As such, when detaching the faucet set main body 10, the water channel 22 is closed automatically.
