Description

A kind of water-saving tap

Technical field

The utility model relates to a kind of water-saving tap.

Background technology

After tap opens the valve of tap by handle, after the water pipe that is connected with tap can be by opening Water tap enters in the faucet of tap, enters into the current after in faucet and can again flow through tap neck, finally Flow out from bib nozzle, after Water tap is closed by tap by handle, although the Water tap energy first after closedown Time blocks the current flowing out in water pipe, makes the current in water pipe cannot be introduced in faucet, but residues in faucet valve Current between door and tap neck then still can flow out from bib nozzle, and this part water is not used by a person, being wasted in vain, Make water resource to be effectively utilized, and further increase water rate expense.

Content of the invention

The technical problems to be solved in the utility model is to provide a kind of water-saving tap, and it can be at handle by Water tap While closedown, the current between residual tap neck and Water tap are retained, under a tap secondary open before, as the One current uses, and makes water resource be effectively utilized.

The technical scheme in the invention for solving the above technical problem is:

The open a kind of water-saving tap of the utility model, including faucet, be located at the handle above faucet and with dragon The leading neck that head body connects, it is characterised in that: in described tap neck, one end is provided with a spring；Described spring is connected with one and retains Piston；It is provided with a bib nozzle connecting with it below described tap neck；Described bib nozzle is curved；The described piston that retains is by dragon The port blocking that head mouth and tap neck connect；Described tap neck one end is arranged over the relief tube connecting with it；Described let out Pressure pipe is externally provided with a spacing ring；Described relief tube is covered with a pressure release cover sealing with its phase；Described pressure release cover is provided with and limits The stroke groove that position ring matches；Described pressure release cover is provided with some relief holes being circularly and evenly distributed, and relief hole is positioned at spacing Above ring；Described relief tube is provided with some air-vents being circularly and evenly distributed, and air-vent is positioned above relief hole, air-vent Connecting with relief tube inner space, air-vent matches with relief hole.

The described piston one end that retains is provided with a pushing part, and pushing part is cone.

The beneficial effects of the utility model are:

Compared with prior art, use the utility model structure water-saving tap can Water tap close same When, by blocking piston, the current residuing between tap neck and Water tap are retained, when using tap next time, The current residuing between tap neck and Water tap can use as first current, makes water resource obtain effectively Utilize, and saved water rate expense to a certain extent.

Brief description

Fig. 1 is the structural representation of the utility model water-saving tap；

Fig. 2 is the enlarged drawing in Figure 1A portion.

Detailed description of the invention

The present invention is further detailed explanation with detailed description of the invention below in conjunction with the accompanying drawings:

Referring to Fig. 1, Fig. 2, the utility model provides a kind of water-saving tap, including the 1st, faucet is located on faucet 1 The handle 2 of side and the leading neck 3 connecting with faucet 1, in described tap neck 3, one end is provided with a spring 4；Described spring 4 It is connected with one and retain piston 5；It is provided with a bib nozzle 6 connecting with it below described tap neck 3；Described bib nozzle 6 is curved； The port that bib nozzle 6 and tap neck 3 connect is blocked by the described piston 5 that retains；Described tap neck 3 one end is arranged over and its phase Through relief tube 7；Described relief tube 7 is externally provided with a spacing ring 8；Described relief tube 7 is covered with a pressure release sealing with its phase Cover 9；Described pressure release cover 9 is provided with the stroke groove 10 matching with spacing ring 8；Described pressure release cover 9 is provided with some circumferentially equal The relief hole 11 of even distribution, relief hole 11 is positioned above spacing ring 8；Described relief tube 7 is provided with some being circularly and evenly distributed Air-vent 12, air-vent 12 is positioned above relief hole 11, and air-vent 12 connects with relief tube 7 inner space, air-vent 12 Match with relief hole 11.

Described piston 5 one end that retains is provided with a pushing part 13, and pushing part 13 is in cone.

Using method of the present utility model is as follows:

When user of service need use tap when, can by be located above faucet water 2 by the valve of tap Opening, opening faucet valve behind the door, the water pipe being connected with tap will make water flow to by the Water tap after opening Enter in faucet 1, can be re-introduced in the leading neck 3 connecting with faucet then into the current in faucet 1, Owing in tap neck 3, one end is provided with spring 4, spring 4 is connected with and retains piston 5, and retains piston 5 one end and be provided with pushing part 13, Therefore, when current constantly enter in tap neck, current can form higher hydraulic pressure, and the hydraulic pressure that current produce then can be to promotion Portion 13 promotes, and makes pushing part 13 move toward spring 4 direction, and pushing part 13 is in hypophysis, can increase to the full extent Pushing part 13 and the contact area of current, increase power on pushing part 13 for the flow action, with the movement of pushing part 13, spring 4 start to shrink at, and retain piston 5 and also begin to mobile, when retain piston 5 move after, retain piston 5 no longer by bib nozzle 6 and tap The port blocking that neck 3 connects, owing to pushing part 13 is in cone, even if therefore pushing part 13 is moved above this port, promotes Portion 13 also will not this port clogging, the current in tap neck 3 then can be entered in bib nozzle 6 by this port, and from tap Mouth 6 flows out for a person to use.

When retaining piston 5 compression spring 4, retaining piston 5 can be compressed to the gas of one end in tap neck 3, is pressed The gas of contracting then can enter in relief tube 7, is had extremely strong air pressure by the gas after compressing, and this strand of air pressure can pass through relief tube Port above in the of 7 makes to cover in and moves on the pressure release cover 9 outside relief tube, and pressure release cover 9 then upwards can move along the track of relief tube 7 outer wall Dynamic, in pressure release cover 9 moving process, stroke groove 10 upper wall surface originally touching with spacing ring phase can depart from spacing ring 8, with letting out Moving on pressure cover 9, the relief hole 11 on pressure release cover can move and flush to the air-vent 12 on relief tube, now enter into relief tube Compressed gas cognition in 7 is discharged to outside tap by air-vent the 12nd, relief hole 11, as the compressed air of tap neck 3 is arranged Going out, the movement retaining piston 5 then will not be caused resistance by compressed air, makes to retain piston 5 under the effect of current hydraulic pressure, can Being promoted easily, and moving as pressure release cover 9 is constantly upper, the lower wall surface of stroke groove 10 can touch with spacing ring 8, pressure release cover 9 cannot move up again, and therefore under the effect of spacing ring 8, pressure release cover 9 will not be by top in compressed gas to disengaging relief tube 7.

When user of service not in use by tap after, then can by handle by the valve closing of tap, in making water pipe Current cannot be entered in faucet 1 by Water tap again, in the closedown of Water tap, tap neck 3 just no longer Having current endlessly to enter, the current hydraulic pressure therefore residuing in tap neck 3 will become low pressure from high pressure moment, works as tap When current hydraulic pressure in neck 3 is low-pressure state, pressure that spring 4 is produced considerably beyond current by the elastic force producing after compressing, this When spring 4 enter horizontal reset by its own resilient to retaining piston 5, retain piston 5 again by bib nozzle 6 and tap neck after reset The port blocking that 3 connect, makes the current remaining between tap neck 3 and Water tap be trapped, when tap is next During use, the current remaining between tap neck 3 and Water tap use as first current, make water resource obtain Effective utilization, and saved water rate expense to a certain extent.
