Abstract

The utility model relates to a gas and water tap, which comprises a shell 8, a water inlet pipe 13, a valve body, a valve cavity and a switch 1. The utility model is characterized in that the valve body is composed of two pistons 6 and 7 which are fixed on the valve rod; the valve cavity is divided into a gas chamber 11 and a gas and water mixing cavity 14 by the pistons 6 and 7, wherein, the gas cavity is communicated with a compressed gas inlet pipe 12, and the gas and water mixing cavity is communicated with a water inlet pipe 13 and a water outlet 10; a through hole 9 is arranged on the lower piston to communicate with the two cavities. Because the impacting force of the water is increased after the compressed gas is introduced, the utility model can cleanly and thoroughly finish the flushing operation with a small amount of water. The utility model verily plays a function of water saving, and also has the advantages of good self sealing performance, and no water leakage.

Description

Gas-water tap

The paddle improvement of mouth of the utility model, particularly a kind of be applicable to the daily flushing of lavatory, hotel, toilet, flushing and family, can water-saving gas-water tap.

Various water nozzle of the prior art, all adopt various technology to leak, accelerate the improvement of configuration aspects such as keying speed, realize water-saving purpose from solution, but still fundamentally using water wisely is because the flushing need of work just can be finished by the impulse force of the water generates of big flow.

The purpose of this utility model is to provide a kind of can mix the gas-water tap that uses with empty G﹠W, to realize that mixing the back with air with a spot of water obtains big impact force, can conveniently wash, again really using water wisely.

Above-mentioned purpose of the present utility model is to realize that by such technical scheme promptly a kind of gas-water tap comprises housing, water inlet pipe, valve body, valve pocket and switch; It is characterized in that: valve body is made of the two-piston up and down that is fixed on the valve rod, by it valve pocket is separated into air cavity and air water hybrid chamber, wherein air cavity and advances the compressed gas air inlet pipe and is communicated with, and the air water hybrid chamber is communicated with water inlet pipe and delivery port, have through hole on the lower piston, two cavitys are communicated with.

Non-limiting the further specifying that said structure of the present utility model is provided by accompanying drawing.

Valve body is a structural representation of the present utility model.

Referring to accompanying drawing: the gas-water tap among the figure comprises housing 8, water inlet pipe 13, valve body, valve pocket and switch 1; It is characterized in that: valve body is made of the two-piston 6,7 that is fixed on the valve rod, by it valve pocket is separated into air cavity 11 and air water hybrid chamber 14, wherein air cavity is communicated with a compressed gas air inlet pipe 12, the air water hybrid chamber is communicated with water inlet pipe 13 and delivery port 10, have through hole 9 on the lower piston, two cavitys are communicated with.

Switch 1 is a button in the above-described embodiments, on the switch supporter 15 that is installed in housing upper end sealing and fixing, switch base 4 is fixed thereon, cover cap 3 is positioned at the switch base top and switch base is fixed, the upper end of valve rod 5 is equipped with spring base and spring 2, and the top of valve rod is passed cover cap 3 and fixed with button.

Usually, under the pressure effect of spring, last lower piston is closed air inlet port and water inlet respectively; When upwards drawing key switch, spring shrinks, and piston leaves gas, water inlet, and compressed air enters air cavity by source of the gas by air inlet pipe, is entered the air water hybrid chamber and is mixed with water inlet by the through hole on the lower piston 9, flows out from delivery port.Instantly press on ﹠ off switch, spring will overcome compressed-air actuated resistance and the descending delivery port of closing at last.

The advantage that the utility model has owing to said structure is conspicuous, promptly owing to increased the impact force of water behind the introducing compressed gas, can totally finish flushing work completely with a spot of water at short notice.Really played water-saving effect, and self sealss are good, water-tight.

The source of the gas that air inlet pipe of the present utility model connect can be the compressed gas station of sub-district or can air-pot etc., and it is little to obtain simple investment.
