Abstract

The utility model discloses a foot-control type antifreezing water tap, comprising a water tap valve body and a water tap switch arranged on the water tap valve body; the water tap switch is connected with a foot-control switch through an operating line; a water inlet pipe of the water tap valve body is provided with a blow-off valve; the arrangement of the foot-control valve can control the opening and closing of the water tap through a foot so as to prevent secondary pollution caused by a dirty hand opening the water tap switch; furthermore, the prior problem of water loss during the process of opening and closing the water tap by hand can be solved through foot control so as to save water resource; and the arrangement of the blow-off valve can lead backflow of water in the water inlet pipe and ensure that the water inlet pipe does not have water when the water tap is not used, thus the water inlet pipe can be prevented from frost cracking in cold winter, and the water tap can be used in the cold winter to save cost for maintaining the cracked water pipe. The foot-control type antifreezing water tap has the advantages of simple structure, sanitary and convenient operation and low cost, and can be accepted by any user.

Description

Foot-control type antifreezing faucet

Technical field

The utility model relates to a kind of water tap, relates in particular to a kind of foot-control type antifreezing faucet.

Background technique

Existing water tap mostly is manual, to water tap be opened with dirty hand before using, such adhere on the water tap unavoidably with dirty, after washing hand, with clean hand water tap is shut, so originally, the hand of wash clean touches contaminated addle tap, cause secondary pollution, and fetching boiling water leading and closing in the process of water tap, the capital has certain water yield to run off, and has wasted water resources, and people have invented inductive water tap at the shortcoming of above-mentioned water tap, but this water tap costs an arm and a leg, and general crowd is difficult to accept.

Secondly, the water tap of public arena in the open, in the winter of cold, as easy as rolling off a log being frozen in, make water pipe from freezing crack easily, cause a large amount of leaking, wasted water resources, increased maintenance expenses, therefore in the winter time the time, the water tap of this open-air occasion all no longer supplies water, and has brought inconvenience to people.

The model utility content

Technical problem to be solved in the utility model provides a kind of with foot control system water tap, and can prevent the foot-control type antifreezing faucet with the bursting by freezing of water tap water pipe.

For solving the problems of the technologies described above, the technical solution of the utility model is: foot-control type antifreezing faucet, comprise tap valve body, be installed in the water tap on the described tap valve body, described water tap is connected with Foot-controlled switch by operating line, on the intake pipe of described tap valve body exhaust-valve is installed.

As a kind of improvement, described Foot-controlled switch comprises that two are the pedal that splayed shape is provided with, and the common ends of described two pedals flexibly connects, and be equipped with and can make described two pedals return to the torsion spring of initial position, the other end of described two pedals is fixedlyed connected with described operating line.

As further improvement, described water tap comprises the dunnage that is arranged on close described water tap place on the described tap valve body, be installed with the spring of realizing that described water tap resets on the described dunnage, described operating line is fixedlyed connected with described spring.

As further improvement, described exhaust-valve comprises the valve body that is fixed on the described intake pipe, described valve body is provided with inner chamber, described inner chamber is communicated with described intake pipe and atmosphere, described inner chamber is the convergence shape with described intake pipe and the atmosphere place of connection, be placed with ball float in the described inner chamber, the diameter of described ball float is greater than the diameter of described two convergences place.

Owing to adopted technique scheme, foot-control type antifreezing faucet comprises tap valve body, is installed in the water tap on the described tap valve body, described water tap is connected with Foot-controlled switch by operating line, on the intake pipe of described tap valve body exhaust-valve is installed; Foot-controlled switch the switch that can control water tap by pin is set, prevented with the secondary pollution that switch brings of turning on the tap of dirty hand, and strikeing with the hand before the control by pin has solved turned on the tap and closed the problem that the water yield runs off in the process of water tap, saved water resources, being provided with of exhaust-valve can make water tap time spent not, water in the intake pipe refluxes, make intake pipe not have water, can prevent that like this winter in cold is with the intake pipe bursting by freezing, water tap also can be used in the winter of cold, saved the maintenance expenses of the water pipe that breaks again, the utility model is simple in structure, the operation hygienic and convenient, and cost is low, and the crowd of any use can be accepted.

Description of drawings

Accompanying drawing is the utility model embodiment's a structural representation.

Embodiment

As shown in drawings, foot-control type antifreezing faucet comprises tap valve body 1, is installed in the water tap 2 on the described tap valve body 1, described water tap 2 is connected with Foot-controlled switch 4 by operating line 3, on the intake pipe 5 of described tap valve body 1 exhaust-valve 6 is installed.

Described Foot-controlled switch 4 comprises, two are the pedal 41 that splayed shape is provided with, the common ends of described two pedals flexibly connects, and is equipped with and can makes described two pedals 41 return to the torsion spring 42 of initial position, and the other end of described two pedals 41 is fixedlyed connected with described operating line 3.

Described water tap 2 comprises the dunnage 21 that is arranged on close described water tap 2 places on the described tap valve body 1, be installed with the spring 22 of realizing that described water tap 2 resets on the described dunnage 21, described operating line 3 is fixedlyed connected with described spring 22.

Described exhaust-valve 6 comprises the valve body 61 that is fixed on the described intake pipe 5, described valve body 61 is provided with inner chamber 62, described inner chamber 62 is communicated with described intake pipe 5 and atmosphere, described inner chamber 62 is the convergence shape with described intake pipe 5 and the atmosphere place of connection, be placed with ball float 63 in the described inner chamber 62, the diameter of described ball float 63 is greater than the diameter of described two convergences place.

Working principle of the present utility model is:

People are when washing one's hands, tramp with one's feet on the Foot-controlled switch 4, two pedals 41 can be on being in a plane under the effect of power, can spur control wire 3 simultaneously opens water tap 2, after washing hand, pin to be moved away, two pedals 41 can recover initial position under the effect of torsion spring 42, while pull operation line 3, water tap 2 is shut under the effect of spring 22.Simultaneously, water tap is pushed ball float 63 top of inner chamber 62 to by the pressure of water when supplying water, the hole plug that inner chamber 62 top convergent are identical with atmosphere seals, when water tap is in closed condition, pressure in the intake pipe 5 produces pressure difference, under the effect that changes pressure and ball float 63 gravity own less than barometric pressure at this moment, ball float 63 produces displacement, air enters intake pipe 5 through inner chamber 62, and water generates refluxes, and the existence of water is not being arranged in the intake pipe 5.
