Abstract

The utility model discloses a foot controlled water tap which is a start-stop water tap controlled by feet. The utility model comprises a water tap, a dragline and a foot controlling device, and the water tap is made by adding a spring tube, a tube and a tube cap on the body and the blocking cover of a common water tap. The utility model has the advantages of easy use, sanitation, saving water and being favorable for a child to open the water tap when washing hand, and the flooding caused by a user forgetting to shut the water tap can be avoided.

Description

Foot controlled water tap

The utility model is a kind of foot control water tap that opens and closes with foot control system.

The water tap that generally uses rotates keying by hand at present.This water tap has a lot of shortcomings: the one, and the hand after cleaning need contact the water tap knob that dirty hand-screw turns over again, can close water tap.Easily cause the cross infection of infectious diseases; The 2nd, when water tap is opened, cut off the water if meet, the user often forgets and closes it.After resuming water supply, a large amount of leakages of water appear through regular meeting.This tends to cause flood.

For addressing the above problem, people design electronics automatic faucet, o-volt protection formula water nozzle (Chinese patent application 85200894), do not have the self closing water tap of pressure (Chinese patent application 85203289) etc.For the electronics automatic faucet, there are the following problems for it: cost height, structure be complicated, need power supply, the water-outlet quantity size is unadjustable, application area is narrow etc.For back two kinds of water taps, still exist manual control easily to cause the problem of cross infection.

The utility model is by the research to man-machine coordination, proposes the keying with foot control system water tap, and on the basis of original water tap improvement a little solves the problems referred to above.

Be described in detail as follows:

The foot control water tap is made up of water tap, stay cord, this three part of foot controller.

See Fig. 1, water tap system by tap main body 1, block up cover 2, manage 3, pipe cap 4, bourdon tube 5 form.The block up minor axis 6 and seal washer 7 drive fits of lid, or minor axis 6 system screw threads are with the fixing (see figure 2) of seal washer 7 usefulness nuts 8.Seal washer 7 can adopt rubber or plastics or other flexible material to make.Tap main body 1, block up cover 2, pipe 3, pipe cap 4 preferably adopt the material that is difficult for getting rusty to make.Bourdon tube 5 is by a compressible spring and wraps up in the pipe that telescopic plastics of length or rubber or other similar material make outward and form.The profile of bourdon tube as shown in Figure 3.The profile of pipe cap 4 is preferably made the hexagon head that is beneficial to loading and unloading.The top of the cornice 9 of pipe 3, the hexagonal profile that is beneficial to loading and unloading is preferably also made at the middle part of pipe.

Stay cord 10 is to be made up of heart yearn 11, flexible pipe 12 and ferrule 13,14.Ferrule 13,14 is all made outside thread.

Foot controller system is made up of arch spring sheet 15, base plate 16.One end of arch spring sheet 15 is connected with hinge type with an end of base plate 16, and the other end of arch spring sheet 15 can freely stretch on base plate 16.This end is opened an aperture 17, so that ferrule 14 is fixed in the front end of arch spring sheet 15 with nut 18.The fixture 20 of the heart yearn 11 of positive stop block 19 and stay cord 10 is housed, so that be fixed on the base plate 16 on the base plate 16 with the end of screw 21 with heart yearn 11.

An end of heart yearn 11 is fixed in to block up and covers on 2 the minor axis 22 in the stay cord 10, and the ferrule 13 of stay cord 10 utilizes screw thread and pipe cap 4 fixing.

During use, pin is stepped on the arch spring sheet 15 on the controller, and it is extended owing to stressed, and comparatively speaking, this end heart yearn 11 is drawn out, driving blocks up cover 2 overcome bourdon tube 5 elastic force and on carry, the faucet subject 1 of fetching boiling water block up 23, water emitted.Pin under the effect of bourdon tube 5, is blocked up and is covered 2 and block again and block up 23 when the arch spring sheet 15 of controller, and water will stop to flow out, and foot control system is to the size of the active force of arch spring sheet 15, then the size of may command water discharge of water faucet amount.

The utlity model has following advantage: 1. man-machine harmony, control is convenient, flexible; 2. health, the cross infection that can ward off disease; 3. water is economized; 4. in the time of can preventing to open water tap, chance be cut off the water, and the user is because of forgetting that closing water tap causes flood; 5. open water tap when helping child and washing one's hands; 6. simple in structure, can improve a little the water tap of original use; 7. the big I regulated at will of flow; 8. owing to wrap up in telescopic rubber or plastic tube outside the bourdon tube 5, water can't enter the inner chamber of bourdon tube 5, can solve ordinary faucet effectively with long afterwards, the generation of swing handle place leakage phenomenon when discharging water.
