With reference to figure 4,5,6 and 7, pull-out spray head 28 comprises the back-up ring 76 that is connected to hose coupling 82 through shell 78.Spring 80 is connected with hose coupling 82 with first joint ring 84.Rubber washer 86, press down nut 88 and rubber sheet gasket 90 is included in the aeration assembly 92.Second joint ring 94 is connected to the aerator housing 96 that is connected with shell 78.
With reference to figure 4,8 and 9, pull-out spray head 28 is configured to make the part of hose coupling 82 to come out from shell 78 inboards and be connected with back-up ring 76, and back-up ring generally is placed on shell 78 tops.Back-up ring 76 is connected with hose coupling 82 by rotation back-up ring 76 on second screwed part 102, and back-up ring 76 and hose coupling 82 can be used as an integral body and move with respect to shell 78 then.What those of ordinary skills expected easily is, can use many other methods to connect back-up ring 76 and hose coupling 82, and wherein a kind of illustrative methods is interlock.Although shell 78 is fixed on the back-up ring 76, when back-up ring 76 was fixed on the hose coupling 82, the formation of pull-out spray head 28 can also make spring 80 be clipped between the annular flange 124 and hose coupling 82 of shell 78.
The formation of first seal ring seat 104 on the hose coupling 82 can be admitted first joint ring 84.First joint ring 84 that places makes hose coupling 82 location and is fixed in the shell 78, and seals shell 78 inboards of first joint ring, 84 tops.Hose coupling 82 is inserted in the shell 78, can cause that therefore 84 contacts of first joint ring and sealing are resisted against the inside of shell 82.And first joint ring 84 makes hose coupling 82 and shell 78 sealings, and the fluid in the pull-out faucet 10 can not be crossed first joint ring 84 on back-up ring 76 directions like this.
The formation of rubber washer 86 is positioned at the ring 122 that presses down nut 88; Like this, after taking a seat, rubber washer 86 and press down nut 88 and become an assembly basically.When pressing down nut 88 rotations aeration assembly 92 is fixed in the aerator housing 96, rubber washer 86 can rotate with pressing down nut 88.Yet rubber washer 86 can keep operation on any angle orientation, even it is with pressing down nut 88 when rotating.Rotate when crossing aeration assembly 92 when pressing down nut 88, press down nut 88 rubber sheet gasket 90 is fixedly leaned against on the aeration assembly 92; Therefore, rubber sheet gasket 90 and aeration assembly 92 all are fixed in the aerator shell 96.
Because hose coupling 82 is connected with back-up ring 76 and aeration assembly 92 is fixed in the aeration housing 96, so shell can be fixed on the aeration housing 96, so that finally assemble pull-out spray head 28.Aeration housing 96 constitutes can admit this second joint ring 94, and when shell 78 being turned to be connected with aeration shell 96, second joint ring 94 is compressed between shell 78 and the aeration housing 96 like this.The compression of second joint ring 94 prevents that fluid from pulling out extending type shower nozzle 28 from shell 78 and aeration housing 96 join domains.
In Fig. 8, pull-out spray head 28 is rendered as the direct current mode, generally represents with Reference numeral 132.Among Fig. 9, pull-out spray head 28 is rendered as the spray mode, generally represents with Reference numeral 130.Can between spray mode 130 and direct current mode 132, change by mobile hose coupling 82, when hose coupling 82 moves to the minimum point of stroke, just can cause to make pull-out spray head 28 enter DC mode 132 like this.Conversely, the peak that makes hose coupling move to stroke can cause and make pull-out spray head 28 enter spray model.
In spray model 130, hose coupling 82 is in the peak of its stroke, and the air deflector limit 112 of air deflector 110 moves up and seals up rubber washer 86 like this.Air deflector limit 112 makes rubber washer 86 sealings can prevent that fluid from continuing to force fluid to flow through the outside that presses down nut 88 thus through this rubber washer 86.Shown in the arrow 134 of the expression flow direction, fluid continues to enter in the annular channel 136, finally ejects from ring sparger 118.
In a preferred embodiment of the invention, ring sparger comprises 16 rectangular opening 142, and size is about 0.04 inch * 0.05 inch.Fluid flows out rectangular opening 142 with the spray column form, compares with the water column that aeration assembly 92 flows out, and these spray columns all can be seen separately.Those of ordinary skills are understood that easily rectangular opening 142 can have various sizes.So rectangular opening 142 can be circular hole or any geometry that other is fit to.And, in order to produce current, can make any suitable shape and size from ring sparger 118.
In DC mode 132, hose coupling 82 is in the minimum point of its stroke, and sealing surface 106 and toroidal bend portion 126 are sealed on the rubber washer 86 like this.After sealing, air deflector 110 is positioned at below the rubber washer 86, and fluid is forced to flow out and enter in the aeration assembly 92 from flow export 108 like this.So fluid can not flow through toroidal bend portion 126 and the zone that rubber washer 86 seals, and has therefore just prevented that any fluid from flowing through ring sparger 118.Similarly, only flow through this aeration assembly 92 with DC mode 132 from the fluid that pull-out spray head 28 flows out with the direct current water-out manners.
In a preferred embodiment of the invention, aeration assembly 92 commercial can be easily from Neoperl, (Waterbury, CT), model name is that Perlator obtains to iNc..When pull-out spray head 28 was in spray model 130 and compares with the water that comes out from ring sparger, the fluid that comes out from aeration assembly 92 was bigger water column, and can not see independent direct current water column.Those of ordinary skills it should be understood that the more final pattern of generation can change by revising aeration assembly 92 or ring sparger 118.
By pull-out spray head 28 being connected with the end of pond 14 necks 26 or taking apart, can between spray model 130 and DC mode 132, switch.When pull-out spray head 28 was fixed on the jet pipe 14, pull-out spray head 28 kept DC mode 132, because the end of neck 26 promotes back-up ring 76 and therefore makes the minimum point of hose coupling 82 down to its stroke.
Pull-out spray head 28 shown in Fig. 8 is in DC mode 132, and similarly, spring 80 constitutes natural relaxation state 138.Pull-out spray head shown in Fig. 9 is in spray model 130, and similarly, spring 80 constitutes compressive state 140.Therefore, along with spring 80 moves (Fig. 9) from release position 138 (Fig. 8) to compressive state 140, will produce elastic force in the spring 80; Like this, spring 80 produces the predetermined force of attempting to turn back to release position 138.
Yet pull-out spray head 28 constitutes and remains on spray model 130, and water or class quasi-fluid flow through pull-out spray head 28.Therefore, the fluid that flows through pull-out spray head 28 with spray model 130 produces enough big pressure on sealing surface 106, make pull-out spray head 28 remain on this spray model 130.Similarly, when fluid mobile discontinuous, the elastic force that the spring 80 under the compressive state 140 produces is enough to make pull-out spray head 28 to return to DC mode 132.Therefore, the elastic force that produces of the spring under the compressive state 140 80 acts on pressure on the sealing surface 106 of hose coupling 28 for 130 times less than spray model gradually.
Typically, when pull-out spray head 28 was fixed on the neck 26, pull-out spray head 28 kept DC mode 132.Wish when neck 26 unloads pull-out spray head 28 when user's (not shown), can catch shell 78 or aeration shell 96 and from leave behind pull-out spray head 28 and handle this shower nozzle arbitrarily of neck 26.When the user when neck 26 is left behind pull-out spray head 28, flexible pipe 66, pouring weight 68 and neck 26 also can stop the action of this pull-out spray head 28 slightly, thereby make and to cause that from the leave behind action of pull-out spray head 28 of neck 26 pull-out spray head 28 is transformed to spray model 130 from DC mode 132.
Notice that as top pull-out spray head 28 if fluid is flowed through, then shower nozzle 28 will keep spray model 130.If there is not fluid this shower nozzle of flowing through, when the action of the pull-out spray head 28 of leaving behind from neck 26 and the power that produces when no longer existing, pull-out spray head 28 just rotates back into DC mode 132.Also have, though can be when fluid flows through pull-out spray head 28 from neck 26 pull-out spray head 28 of leaving behind, the user can close water tap 10 makes fluid no longer flow through pull-out spray head 28 and the thing of going to do other.When cutting off fluid mobile, pull-out spray head 28 rotates back into DC mode 132.No matter pull-out spray head 28 is connected with neck 26 or dismantles, the perhaps fluid pull-out spray head 28 of whether flowing through, the user can be by hand propelled or pulling back-up ring 76, so as between spray model 130 and DC mode 132 manual switchover pull-out spray head 28.
The user can also dismantle pull-out spray head 28 down from the neck 26 of water tap 10 by back-up ring 76 rather than shell 78 or the aeration housing 96 of catching pull-out spray head 28.Do like this, prevented that pull-out spray head 28 from switching to spray model 130.User's grasping and spur back-up ring 76 continuously makes pull-out spray head 28 switch to spray model 130 from DC mode 132.
It should be understood by one skilled in the art that back-up ring 76 can have many forms, perhaps can not comprise pull-out faucet 10.For example, back-up ring 76 can take button or axle collar form to be fixed on the flexible pipe 66, or the shower nozzle controlling organization that switches between a plurality of spray models of pull-out spray head 28 of any help user.Similarly, those skilled in the art should also be understood that spray model 130 and DC mode 132 or typically spray pattern and pull-out spray head 28 can constitute the spray type structure of replacement.
Figure 10 to 14 has represented according to the present invention the pull-out spray head 28 of an alternative preferred embodiment structure.Similarly, represent same structure among each embodiment with the Reference numeral of representing same structure.It should be understood by one skilled in the art that public next structure can be exchanged with other embodiment among any one embodiment.Should also be understood that the embodiment of the invention disclosed herein all is descriptive, is not to limit the invention in the disclosed embodiments.
With reference to Figure 10,11 and 12, pull-out spray head 28 comprises upper shell spare 200, and upper shell spare is connected and forms jointly hereinafter a housing 204 with lower shell piece 202.Mobile collar 208 is included in the shell 204 and comprises the threaded portion 236 that can be connected with flexible pipe 66, and flexible pipe passes through this upper shell spare 200.Spring 206 remains on and flows between the collar 208 and the upper shell spare 200.The collar 208 that flows comprises the base 210 of positioning tab 238 and mobile collar packing ring, wherein is shelved with the collar packing ring 212 that flows.The collar 208 that flows also comprises flow duct 214, sealing ring base 216 and flow duct lower seal base 218 on the flow duct.Flow duct upper gasket 220 is seated on the flow duct on the sealing ring base 216, and flow duct lower gasket 222 is seated on the flow duct lower seal base 218.
The flow duct 214 of the mobile collar 208 can move around in the medium pore 224 that is limited by converter 226.Converter 226 also limits and is centered around medium pore 224 a plurality of looping pits 228 on every side.Should be appreciated that medium pore 224 is not to be connected communicatively with a plurality of looping pit 228 fluids, vice versa.In addition, when lower shell piece 202 was connected with upper shell spare 200, converter 226 was connected to lower shell piece 202 and is fixed on the appropriate location.
Be fixed between converter 226 and the lower shell piece 202 is ring sparger 230.Current screen cloth 232 is arranged in ring sparger 230.Place current screen cloth packing ring 234 between converter 226 and the current screen cloth 232.Similarly, when upper shell spare 200 was fixed on the lower shell piece 202, converter 232 was fixed on current screen cloth packing ring 234, current screen cloth 232 and ring sparger 230 in the lower shell piece.
Upper shell spare 200 constitutes the spring 206 between the external surface 242 that can comprise flange 240 and mobile collar packing ring base 210.Retainer lug 238 can make the collar 208 that flows remain in the upper shell spare 200.Upper shell spare 200 also can constitute is connected on the conventional threads lower shell piece 202.Those of ordinary skills expect having many methods can assemble shell easily; Some examples comprise interlock, bonding or mechanical fasteners connection like this.
With reference to Figure 13 and 14, pull-out spray head 28 is rendered as DC mode (Figure 13) and the general spray model of generally being represented by Reference numeral 132 (Figure 14) by Reference numeral 130 expressions.The mobile flow duct 214 that causes of the mobile collar 208 moves around in the medium pore 234 of converter 226.When pull-out spray head 28 was in DC mode 132, the collar 208 that flows reached the bottom position in the shell 204.In DC mode 132, flow duct upper gasket 220 enters in the medium pore 224 of converter 226 and makes its sealing.When pull-out spray head 28 was in spray model 130, the collar 208 that flows reached auto-summit.In spray model 130, flow duct lower gasket 222 is sealed in the medium pore 224, makes flow duct 214 be positioned at the inlet top of medium pore 224 thus.
In DC mode 132, flow duct upper gasket 220 has entered in the medium pore 224 and has made its sealing.Similarly, flow duct 214 is sprayed water outlet below the medium pore 224 of sealing.Because flow duct upper gasket 220 has made the medium pore 224 above the flow duct 214 seal up, therefore the water that ejects from flow duct 214 is merely able to come out through the mobile screen cloth 232 of pull-out spray head 28.
In spray model 130, flow duct lower gasket 222 has made medium pore 224 seal up.Because medium pore 224 has sealed up, therefore the water that flows out from flow duct 214 must flow through a plurality of looping pits 228 of converter 226.The water that flows through a plurality of looping pits 228 flows through ring sparger 230 then.
