Abstract

The utility model relates to a keying water tap, which has the advantages of convenient portability, labour saving, no streamlet water drop, no water leakage, small abrasion, long service life and adjustable flow quantity, can prevent sputtering, and does not need to repair or replace parts often. The utility model mainly comprises a valve body, a valve cap, a sealing rubber, a slide block, a valve core, a sliding sleeve, a self locking key, a flow regulator, etc.; the sliding sleeve and the valve core can move up and down by pressing lightly the self locking key; the water pressure of the both portions of the water cavity of the keying water tap is not balanced, and the switching of a waterway can be controlled by lifting and pressing the sealing rubber and the slide block; the keying water tap can be opened and closed by touching lightly the key twice by a finger; the utility model has the advantages of novel structure, beautiful appearance and reliable action.

Description

The push key type water tap

The utility model relates to a kind of water tap, is mainly used among the people and industrial department.

Present widely used water tap is generally rotary, ball-valve type and push button, and their common issue with is that the sealing material wearing and tearing are big, easily leaks, and the life-span is short, the thread water droplet is often arranged, unfavorable water saving.At least must operate by two fingers during use, also require great effort, very inconvenient.The public place uses this class water tap very unhygienic, is reluctant to close after the someone uses up again, and causes water waste.The someone produced human body induction type and infrared control water tap in recent years, Touchless manipulation, and more advanced and health, but power supply and special-purpose control wiring, complex structure must be provided, and volume is bigger, and product cost height is difficult to promote.

The purpose of this utility model is to overcome above-mentioned shortcoming, provides a kind of easy to use, health, life-span long, water-tight, simple in structure, the water tap that cost is low.

The purpose of this utility model is achieved in that lockmaking and the release that utilizes locking key, drive a magnet ring, by magnetic force, and by the pressure of tap water own, play partition in the control water route and open the mechanism action of effect, to realize that water tap is opened and closed.This structure amount of movement is little, and it is atomic to wear and tear, and the life-span is long.There is not seepy question in movable part in the water route with outer isolated.Utilized hydraulic pressure to be used as power simultaneously, thus use the utility model water tap very laborsaving, convenience, also health.

Exhausted most part of the present utility model, all available injection moulding extrusion modling is convenient to produce in enormous quantities, and cost is low, and is good in economic efficiency.

Concrete structure of the present utility model is provided by following examples and accompanying drawing thereof.

Accompanying drawing is that the utility model is closed strip log, puts up with the concrete device details and the working condition of proposition below and does an explanation:

The utility model is locking key (11), sliding sleeve (10), spool (18), slide block (23) and valve gap (7), all coaxial vertically being installed on the valve body (4).Valve body (4) water inlet end is 1/2 inch close nipple of standard, in mouthful wire netting (5) is arranged, and enters in the valve with foreign material in the waterproof, and the outlet pipe lower end then is flow regulator (25), and splashproof perforation (26) is arranged.Locking key (11) contains peach type guiding groove (16) and screens spring (15), is fixed on upper end in the valve bonnet (14) with screw (12), is screwed on the valve body (4) by its lower end snail button.Ring-like nut (19) is fixed in valve body (4) top to valve gap (7), and compresses seal ring (6), guarantees that tap water can not spill.Magnet ring (17) and reset spring (8) are arranged in the sliding sleeve (10), be enclosed within outside valve gap (7) vertical tube, and withstand button (13).Spool (18) in valve gap (7) vertical tube, the upper end is soft iron (9), the lower end is rubber stopper (20).Slide block (23) in the valve body (4), sealed rubber (3) all has center hole (24) and bypass opening (22), and water cavity is divided into two ones up and down.

Working principle of the present utility model is, when clicking button (13), screens spring (15) makes its pinning, and (locking key (11) is a peach type locking mechanism, do not cut open in the detailed drawing and show), key lever promotes sliding sleeve (10) and magnet ring (17) moves down, magnetic force holds soft iron (9) also moves down spool (18), so rubber stopper (20) blocks the center hole of slide block (23) (24).At this moment water enters upper water cavity (21) from bypass opening (22) and forms big hydraulic pressure, forces slide block (23) and sealed rubber (3) to push down the mouth of a river (1), leading anhydrous outflow (as the accompanying drawing shape).If press button (13) again, screens spring (5) enters guiding groove (16), locking key (11) release, and Returnning spring (8) promotes to move on the sliding sleeve (10), and spool (18) moves on also.So rubber stopper (2) leaves center hole (24), the water of upper water cavity (21) flows into outlet pipe (1), and hydraulic pressure descends.This is the high pressure tap water of water cavity (2) at present, just sealed rubber (3) and slide block (23) is held up, and leading water route communicates, and water promptly flows out.So use the utility model need only press button, water tap just is opened and closed (13) twice.
