In order to be better understood by technology contents of the present utility model, especially exemplified by specific implementation method and coordinate institute's accompanying drawings explanationIt is as follows.
With reference to figure 1-5, a kind of gondola water faucet, including：Gondola water faucet body 1 and sealing switching valve element 2；The gondola water faucet body 1 includesWater surface lid 11 and handle 12, the sealing switching valve element 2 are arranged in handle 12.
Described sealing switching valve element 2, including：Fixing axle 21 and the switching for being placed in co-axial setting in fixing axle 21Axle 22；The operating parts 3 of switching shaft 22 and one, which interlocks, to be set so that switching shaft 22 is in the fixing axle 21 axially theMoved between one position, the second place and the 3rd position；
One end of the switching shaft 22 is water inlet end 221, the other end is water side 222, forms a water excessively axiallyRunner；When the switching shaft 22 is located at first position, the water inlet end 221 is closed to form sealing state；The switching shaft 22During positioned at the second place, the water inlet end 221 is opened, and the side wall of switching shaft 22 is close to the side of water side 221 and fixationAn air inlet 223 is formed between axle 21, when current are flowed into fixing axle 21 by water side 222, because the diameter of fixing axle 21 is bigDiameter in the water side 222, produce Venturi effect and air suck from the air inlet 223 to fixing axle 21 is interior and waterStream mixing, forms air suction sprinkler water water outlet；When the switching shaft 22 is located at three positions, the water inlet end 221 stays open shapeThe state and air inlet 223 is closed, form light water water outlet.
Water inlet end 221 is closed in unidirectional moving process reach only as described above, said structure realizes switching shaft 22Water state, air inlet 223 is either closed, water inlet end 221 is opened and reaches common gondola water faucet water water outlet or air inlet 223 and enterWater end (W.E.) 221 is opened simultaneously reaches air suction sprinkler water water outlet.Therefore, pass through the unidirectional movement of switching shaft 22, it becomes possible to realize sealing,The switching of light water and function water Three models, the comparison that operates are easy.
In order to realize switching shaft 22 at first position, water inlet end 221 is closed, and following structure is used in the present embodiment：
Also include the first seal 23 being coaxially disposed with the switching shaft 22, the first seal 23 is axially setThe rear of the water inlet end 221 is placed in, when the switching shaft 22 is located at first position, the end face of the water inlet end and described firstThe contact of seal 23, so as to close the water inlet end 221.
Specifically, the installation site of the first seal 23 is：The fixing axle 21 is close to the water inlet end 221Side is connected with water supply connector 24；The water supply connector 24 has an accommodating cavity 241 close to the side of water inlet end 221；DescribedOne seal 23 is arranged in the accommodating cavity 241；Current are flowed into the accommodating cavity 241 by water supply connector 24, and are only capable ofFlowed into by the water flow passage of crossing in the fixing axle 21.
In order to ensure the stability of sealing, when first seal 23 seals with the contact of water inlet end 221, first seal is necessaryKeep the state being bonded with water inlet end, and can not be extruded by first seal 23 and be moved rearwards cause to seal it is unreliable.ForSolve this problem, the both sides of the first seal 23 axially respectively with an elastic component 231 and the contact of support member 232Set；When the switching shaft 21 is located at first position, the elastic component 231 to first seal 23 produce support force, make its withThe end face of the water inlet end 221 keeps palette state；When the switching shaft 22 is located elsewhere, the elastic component231 drive first seals 23 are reset to the initial position with the contact of support member 232.Because elastic component 231 provides elastic resetPower, when the end face of water inlet end 221 is with 23 contact of first seal, the elastic reset power and water inlet end 221 that elastic component 231 provides are rightFirst seal 23 compresses force direction on the contrary, this makes it possible to ensure that first seal 23 will not axially draw back, and beginsThe end face gluing, sealing with water inlet end 221 is kept eventually.
On the basis of said structure, the support member 232 has a resigning hole axially worn, the switching shaft22 water inlet end 221 enters in the accommodating cavity 241 through the resigning hole；So support member 232 would not be to switching shaft 22Movement causes to hinder.
In addition, in order to be introduced into the current in water supply connector 24 in the part accommodating cavity 241 where water inlet end 221, instituteStating the periphery of support member 232 also has a water inlet perpendicular to axial direction, water flow through pass through again after water supply connector 24 flows into described in enterThe mouth of a river is flowed into the accommodating cavity 241.
In addition, in order to ensure the reliability of sealing, as described above, current flow into the accommodating cavity by water supply connector 24In 241, it is only capable of flowing into the fixing axle 21 by the water flow passage of crossing.So after water inlet end 221 is closed, there will be noCurrent enter in fixing axle 21.But in above-mentioned structure, current can pass through the water inlet of support member 232, and support member is alsoResigning hole is offered, current inevitably flow out from resigning hole.
In order to solve this problem, the outer wall of the switching shaft 22 is additionally provided with the second sealing close to the side of water inlet end 221Part 224, by the gap sealing between the switching shaft 22 and resigning hole so that the current in the accommodating cavity 241 are only capable of passing throughThe water flow passage of crossing is flowed into the fixing axle 21.
Further, one side of the first seal 23 away from the water inlet end 221 and the rear end of the accommodating cavity 241Between there is a fixed gap；When the switching shaft 22 is located at first position, the water inlet of current from support member 232 flow to accommodating cavityIn 241 so that the first seal 23 axially on obverse and reverse in all by the pressure of current, the pressure sizeEqual direction is on the contrary, be in hydraulic balance state.So switching shaft 22 need not just overcome the resistance of current during movement,It is also relatively good to switch the lighter feel of power.
In order to realize air suction sprinkler water, in the present embodiment, the switching shaft 22 is also set close to the side of the water side 222There is the 3rd seal 225；Axially there is interconnected first chamber 211 and second chamber 212 in the fixing axle 21,The diameter of the first chamber 211 is less than second chamber 212 so as in the connectivity part shape of first chamber 211 and second chamber 212Into a step surface 213；Current are flowed into the first chamber 211 by the water side of switching shaft 22；In order to realize Venturi effect,The diameter of first chamber 211 is greater than the diameter of water side 222 so that current are sent out when entering first chamber 211 by water side 222The mutation of raw discharge area, produces Venturi effect.
During the switching shaft 22 moves from first position to the 3rd position, the 3rd seal 225 towards byThe direction movement of the nearly step surface 213；When the switching shaft 22 is located at the second place, the 3rd seal 225 and platformTerrace 213 not in contact with, therefore between the outer wall of the switching shaft 22 and step surface 213 have a gap form the air inlet223；When the switching shaft 22 is located at three positions, the 3rd seal 225 and the contact of step surface 213, by the air inletMouth 223 is closed.It is achieved thereby that the switching of the water outlet of air suction sprinkler water and light water water outlet.
Further, the operating parts 3 is button, and the button 3 has outside the body 1 in the body 1One fixed seat 13；One end of the button is rotatablely connected with fixed seat 13, and the other end is press-side；
The fixed seat 13 is also rotatablely connected with a swinging block 14, when the press-side of the button 3 pushes, the swinging block14 are swung by the extruding of button 3, and the swinging block 14 interlocks in swing process with a drive block 15, the drive block 15The swing of swinging block 14 is converted into movement axially；Switching shaft 22 is driven to move when the drive block 15 moves in the axial directionIt is dynamic.So it is achieved that pressing button 3 drives switching shaft 22 axially to move backward, that is, from the 3rd position to firstPut motion.
In order to realize that switching shaft 22 axially travels forward, the periphery of the switching shaft 22 is arranged a return unit 226, shouldOne end of return unit 226 and the contact of switching shaft 22, the other end and the contact of support member 232；The switching shaft 22 from the 3rd position toDuring first position movement, the return unit 226 is extruded accumulation elastic reset power.When drive block 15 and switching shaft 22Between contact relation broken when, switching shaft 22 just moves in the presence of elastic reset power from first position to the 3rd position.
