Description:

BACKGROUND OF THE INVENTION

1) Field of the Invention

A kind of normal-opened-model vacuum eliminator, in which some interlinked vents are designed on the larger ring-shaped side of the pressure controller, and a leakage-proof pad is designed on the ladder-shaped side for the pressure-resisting ring. In that way, the pressure-resisting ring is pushed towards the pressure controller and the leakage-proof pad exactly would be absorbed by vacuum at the edge of central hole of the pressure controller in the case of water's access to the non-returning pipe. And the pressure-resisting ring can eliminate the vacuum absorption with its gravity and air suction and block backward the water inlet edge of the non-returning pipe to prevent the water flow's reflux from access to the interior of the non-returning pipe. Thereby, it not only would not easily be involved in denaturation and failure, but also has simple structure and exact operation besides its easy assembly.

2) Description of the Prior Art

Generally, the conventional vacuum eliminator of water faucet, referring to FIG. 1 is composed of a seat hole 5 transversely on a valve base, whose internal end is interlinked with a pipe when its outer end forms a mouth, a stopper 6 fixed on the base hole and interlinked with the base hole, a sliding block 7, which can be installed in the base hole and its interior has many guide chutes 71, moreover a set of leakage-proof pads 8 opposite the perforation. For the forgoing units, the vacuum can be eliminated in the pipe.

Nevertheless, we find out that the forgoing prior art is not so fine as we expected. Because all its parts are made of plastic materials, they not only would be easily involved in denaturation and failure, but also the outside force is required to block backward the water inlet edge for its small weight while operating themselves. More seriously, its action would be incorrect.

SUMMARY OF THE INVENTION

The normal-opened-model vacuum eliminator the prevent invention provides, whose larger ring-shaped side exactly reaches the water inlet edge of the non-returning pipe, in which some interlinked vents are designed on the larger ring-shaped side of the pressure controller, and a leakage-proof pad is designed for on the ladder-shaped side for the pressure-resisting ring. In that way, the pressure-resisting ring is pushed towards the pressure controller and the leakage-proof pad exactly would be absorbed by the vacuum at the edge of central hole of the pressure controller in the case of water's access to the non-returning pipe. And the pressure-resisting ring can eliminate the vacuum absorption with its gravity and air suction to form an unobstructed water flow and block backward the water inlet edge of the non-returning pipe to prevent the water flow's reflux from access to the interior of the non-returning pipe to expand the service life of water transport pipeline and balance the returning water operation safety. Thereby, it not only would not easily be involved in denaturation and failure, but also has simple structure and exact operation besides its easy assembly.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS

Referring to the FIG. 2 and FIG. 3, the present invention is to put the screw locking end 31 on the both sides of the water faucet 3 through the shutter S of the granite counter to connect the locking unit 4 and position the water faucet 3 on the shutter S. in which, the locking unit 4 is composed of a locking screw cap 41 for the screw locking end 31, and a packing piece 42 locked in the locking screw cap 41 and a non-returning pad 43, and a water supply pipe 45 whose end and packing piece 41 are fixed and extruded outwards from the lockhole 44. It can prevent the water from seeping by means of tightly jointing with the non-returning pad 43 in the locking screw cap 41 after the locking screw cap is screwed on the screw locking end 31 of the water faucet.

In addtion, referring to the FIG. 4, the water flow is vertically guided by the water supply pipe to the locking screw cap 41 and lockhole 44, and then to the interior of water faucet 3 through the screw locking end 31 to keep the water flow in the water faucet 3 for supply waiting in the water control circuit. Thereby, based on the arrangement of the structure, because the water faucet 3 is designed directly with a locking unit 4 on the screw locking end 31 to make the water flow can access direcly through the locking screw cap 41 and lockhole 44 of the locking unit 4 and position the water faucet 3 on the shutter S. The distance L between shutter S and wall W can be shortened properly to save space and consumptive materials.

As shown in FIG. 2 and FIG. 3: the present invention comprises: a non-returning pipe 1, a pressure controller 2 and a pressure-resisting ring 3, in which

The non-returning pipe 1 is a three-way pipe including water inlet 11, water outlet 12 and air inlet 13;

The pressure controller 2 is T-shaped, and its larger ring-shaped side 21 exactly resists the water inlet edge 13 of the non-returning pipe 1, in which some interlinked vents 211 are designed on the larger ring-shaped side of the pressure controller. When the air enters into from the interlinked vents 211, the vacuum absorption state of the pressure controller 3 and the pressure-resisting ring 3 can be eliminated to make the pressure-resisting ring 3 block backward the water inlet edge 11 of the non-returning pipe 1 for avoiding the water flow's reflux; and a perforation 23 is designed on the larger ring-shaped side 21 for the pressure controller 2, which is fixed with a cover 4 by a bolt T to form a closed state;

The front end 3 of the pressure-resisting ring extrudes a little into the guide head 31 in the central hole of the pressure controller, and a leakage-proof pad P is designed on the ladder-shaped side 32 for the pressure-resisting ring 3. In that way, the pressure-resisting ring is pushed towards the pressure controller 2 and the leakage-proof pad P exactly would be absorbed by the vacuum at the edge 22 of central hole of the pressure controller 2 in the case of water's access to the non-returning pipe to form an unobstructed water flow;

As shown in FIG. 4: it is an embodiment of water flow in accordance with the present invention. When the non-returning pipe 1 is under the state of water supply, the pressure-resisting ring 3 exactly can be pushed by the water to make the leakage-proof pad P on the ladder-shaped side 32 can be absorbed on the edge 22 of central hole of the pressure controller by the vacuum. At this time, the air at the outside of blowhole 21 of the pressure controller 2 is resisted by the pressure-resisting ring 3 and fails to access to, so that the water flow can enter into the water inlet 11 of the non-returning pipe smoothly and outflow the water outlet 12 (as shown in FIG. 4-A);

And because the pressure-resisting ring 3 hasn't the water flow pressure to resist under the water stopping state, the air at the outside of pressure controller 2 can enter into the non-returning pipe 1 through the blowhole 21 to eliminate the vacuum absorption of the pressure controller 2 and pressure-resisting ring 3 and form an inlet valve room R. And the pressure-resisting ring 3 blocks backward the water inlet edge 11 of the non-returning pipe 1 with its gravity and air suction to make the water flow from the water inlet 11 and would not return to the non-returning pipe with some foreign substance for good water resources and longer service life of the water transport pipeline, balancing the returning water operation safety (as shown in FIG. 4-B);

Because the pressure controller 2 and the pressure-resisting ring 3 are made of metal materials, the pressure-resisting ring 3 can eliminate the vacuum absorption with its gravity. And it not only would not easily be involved in denaturation and failure, but also has simple structure and exact operation besides its easy assembly.
