BACKGROUND OF THE INVENTION

1. Field of the Invention

The present invention relates generally to a component of drinking water equipment, and more particularly to the innovative structure type of a faucet that can be equipped with an air gap device.

2. Description of Related Art Including Information Disclosed Under 37 CFR 1.97 and 37 CFR 1.98

Reverse osmosis water treatment equipment will produce wastewater in the course of water treatment. The wastewater is discharged through the drain line. An air gap device is arranged in the upstream water pipe of wastewater drain line, so as to prevent the wastewater from entering water system through the drain line due to siphonage.

U.S. Pat. No. 7,011,106B2 and U.S. Pat. No. 7,357,147B2 patent documents disclose a faucet with an air gap device, including a main body, a valve and an air gap device, wherein the main body defines an inlet and an outlet, a valve chamber is located between the inlet and the outlet, an air gap chamber forms an opening at the first end of the main body, wherein a vent enters the air gap chamber through the wall of the main body. The valve is located in the valve chamber for controlling the liquid to flow from the inlet to the outlet. The air gap device comprises a holder and an air gap structure, the holder and the air gap structure are located in the air gap chamber.

The vent penetrates the wall on one side of the main body. Before the air gap chamber is equipped with the air gap device, a movable cover is installed on the main body to block the vent, no matter whether the main body is provided with the cover, the vent or the cover destroys the appearance integrity of the faucet.

BRIEF SUMMARY OF THE INVENTION

The main purpose of the present invention is to provide a faucet that can be equipped with an air gap device.

Based on the aforementioned purpose, the faucet that can be equipped with an air gap device of the present invention which comprises a base, a chamber is formed inside the base, and an air gap device is disposed in the chamber, the chamber extends to the bottom of the base.

A main body is disposed on the top edge of the base, and a valve chamber, a first channel and a second channel are formed inside the main body. The first channel communicates with the valve chamber and the chamber, the second channel communicates with the valve chamber and the outside of the main body, so that an inlet pipe communicates with the first channel. An outlet pipe communicates with the second channel, and the water enters the valve chamber through the inlet pipe and flows out through the outlet pipe.

A control valve is disposed in the valve chamber, so as to control the water to flow from the first channel to the second channel.

A support block is located between the base and the main body, so that a gap is formed between the base and the main body. The gap communicates with the chamber through at least one connecting passage, and the gap communicates with the space outside the faucet, so that the air enters or leaves the chamber through the gap.

The main effect and advantages of the present invention are that the gap is formed between the base and the main body, the air can enter or leave the chamber through the gap, the overall appearance of the faucet is free of visually attractive vents, and the integrity of the appearance can be maintained.
