Abstract

A tap includes a valve 21 resiliently mounted in a hollow stem 11 and a nozzle 31 movably inserted in the hollow stem so that the nozzle may be depressed to open valve 21 to spray water upwards when the main valve is closed; after pulling the nozzle 31 upwards, valve 21 is automatically closed to stop water flow by a restoring spring 25 resiliently backing the valve 21 and supported by an apertured plate 24 mounted on valve stem 22. <IMAGE>

Description

SPECIFICATION The present invention relates to a tap.
Known taps serve the single function of dispensing a liquid such as water so that if a spray is required, a separate shower hose is needed. For rinsing the mouth or teeth, a cup may be used to receive water from a tap but this is inconvenient.
Conventional dental water spray requires an electric pumping system for filling water into a container which is normally maintained in a filled condition ready for use.
According to the present invention there is provided a tap with a built-in needle valve comprising: a hollow stem formed with a hollow tube with open ends, a needle valve resiliently mounted in said hollow stem tube; and a nozzle movably inserted into said hollow stem tube above said needle valve which comprises a needle rod having an extension tip formed on the top thereof, a perforated spring retainer which is formed on the central portion of said needle rod and is perforated with several holes to permit the passage of water therethrough, a restoring spring backed by said spring retainer and inserted into said hollow stem tube, and a tapered plug formed on the lower portion of said needle rod to seal against a tapered seat formed in said hollow stem tube; and a nozzle which is formed with a hollow nozzle adaptor inserted into said hollow stem tube and including sealing means to prevent from water leakage.
The invention will now be described further by way of example with reference to the accompaying drawings in which: Figure 1 is a sectional drawing of a tap in accordance with the present invention; Figure 2 is an exploded view of several parts of the tap illustrated in Fig. 1; and Figure 3 is a partial sectional drawing of another part of the tap shown in Fig. 1.
The tap shown in the Figures has a hollow stem 11 which is formed with a hollow stem tube 11" with open ends, a needle valve 21 being resiliently mounted in the lower part of the hollow tube 11". A nozzle 31 is movably inserted in the hollow tube 11" at a position above the needle valve 21.
Needle valve 21 comprises an elongated needle rod 22, having an extension tip 23 formed at its top end. A perforated spring retainer 24 is fixed on a central portion of rod 22 the perforations 24a allowing for the passage of water. One end of a restoring spring 25 lies against the spring retainer 24, a tapered rubber plug 26 normally sealing the tapered seat 1 lea" formed is hollow tube 11".
-The nozzle 31 is formed with a hollow adaptor 32 which is movably inserted into the hollow tube 11" and is jacketed with two sealing rings 33A, 33B for preventing water leakage from stem 11. A pressing plate 34 is centrally formed on the bottom edge of nozzle adaptor 32. Plate 34 is a slim plate.
The hollow stem 11 is formed with both longitudinal grooves 13 and transverse threads 14 for locating and fixing the tap head 16.
The stem 11 is formed also with course threads 15 for mounting the sleeve 12.
When using the present invention for spraying water upwards, the nozzle 31 is depressed to press the extension tip 23 of the needle valve 21 to lower the tapered rubber plug 26. The action permits water to flow upwards through passages 27, passages besides pressing plate 34 of the hollow syringe adaptor 32 and finally to spray outwards for rinsing use. When it is not used, the syringe 31 is raised so that the restoring spring 25 will force the retainer 24 and needle valve 21 upwards to allow rubber plug 26 sealing the tapered stem 1 1a" to stop water spray.
The present invention is superior to conventional taps in the following respects: 1. The tap can serve a dual use, i.e., for spraying water upwards directly from the hollow stem and also for normal tap use by operating the tap head as usual.
2. The tap is constructed in a more economical way but can perform the double uses as above-mentioned.
1. A tap with a built-in needle valve comprising: a hollow stem formed with a hollow tube with open ends, a needle valve resiliently mounted in said hollow stem tube; and a nozzle movably inserted into said hollow stem tube above said needle valve which comprises a needle rod having an extension tip formed on the top thereof, a performated spring retainer which is formed on the central portion of said needle rod and is perforated with several holes to permit the passage of water therethrough, a restoring spring backed by said spring retainer and inserted into said hollow stem tube, and a tapered plug formed on the lower portion of said needle rod to seal against a tapered seat formed in said hollow stem tube; and a nozzle which is formed with a hollow nozzle adaptor inserted into said hollow stem tube and including sealing means to prevent from water leakage.
2. A tap as claimed in claim 1 in which the nozzle is centrally formed with a thin pressing plate on the bottom edge of the adaptor, which allows water to pass into the hollow nozzle besides said pressing plate for spray use.
3. A tap substantially as herein described with reference to and as illustrated in the accompanying drawings.
