Fig. 1 shows shower bath 10, and it has provides the handle 14 of controlling for grasping of user.Illustrated shower bath 10 comprises handheld shower device.In another structure, (not shown) shower bath 10 can comprise different shower baths, for example shower head, rain gondola water faucet, wall embedded type water magic square gondola water faucet, etc.Shower bath 10 comprises entrance 18, and it is communicated with multiple outlet nozzle 22 fluids.Entrance 18 is connected to receive current from water system (not shown) with fluid line 26.

Fig. 2 shows the profile of the handle 14 of shower bath 10 and the area part of entrance 18.Shower bath 10 comprises main water-flowing path 30 and the alternative auxiliary water circulation flow path 34 of opening, and auxiliary water circulation flow path 34 is for providing overall flow rate larger when only opening main water-flowing path 30 at outlet nozzle 22 places.In the structure illustrating, at least a portion of main water-flowing path 30 and auxiliary water circulation flow path 34 is defined by the inner surface of handle 14.(not shown) in other structure, shower bath 10 can comprise one or more independent water routes of passing handle 14 and extend, so that water does not directly contact the inner surface of handle 14.

Shower bath 10 comprises two pressure compensated flow control device: master selector 38 and secondary controller or auxiliary governor 42.Master selector 38 and auxiliary governor 42 limit the speed of the current wherein of flowing through, and for example, adjuster 38 and 42 cuts out voluntarily in the time of the pressure of upstream side, to limit the flow velocity of flowing through wherein.

Main water-flowing path 30 is to regulating the current of flow velocity to guide through master selector 38.Therefore, main water-flowing path 30 maintains low flow velocity, i.e. low discharge pattern is applicable to most of shower functions (drench, warming etc.).The water velocity that the water velocity of controlling due to master selector 38 regulates lower than auxiliary governor 42, therefore, under low discharge pattern, auxiliary governor 42 is actually inactive.

Auxiliary water circulation flow path 34 is to regulating the current of flow velocity to guide through auxiliary governor 42.The flow velocity limit value that the flow velocity limit value that auxiliary governor 42 provides provides higher than master selector 38, auxiliary governor 42 is positioned at the upstream of master selector 38, and also i.e. main water-flowing path 30 of auxiliary governor 42 and master selector 38() and auxiliary water circulation flow path 34 connect.In other words, main water-flowing path 30 and auxiliary water circulation flow path 34 both pass through auxiliary governor 42.Therefore, auxiliary governor 42 regulates the total water current speed of flow through main water-flowing path 30 and auxiliary water circulation flow path 34.On the contrary, through master selector 38 only have a main water-flowing path 30, so master selector 38 only regulates the water velocity of the main water-flowing path 30 of flowing through.

The normality of auxiliary water circulation flow path 34 is closed condition.Driving mechanism or button 46 are connected with instantaneous valve member 50, and instantaneous valve member 50 is closed auxiliary water circulation flow path 34 when near valve seat 58.In the structure illustrating, valve seat 58 is integral parts of the entrance 18 of shower bath 10.(not shown) in other structure, shower bath 10 can comprise the independent valve body that valve seat 58 is provided and supports valve member 50.

Valve member 50 leans against closing position (as shown in Figure 2) partially to close auxiliary water circulation flow path 34.In the structure illustrating, valve member 50 is in the fluid pressure below-center offset of auxiliary water circulation flow path 34 inside and closure.Can use alternatively spring 54 to exert an influence to the needed power of activation button 46.Spring 54 is arranged between valve member 50 and the fixing inner surface of shower bath 10.

As previously mentioned, in the structure illustrating, main water-flowing path 30 is always open mode.When button 46 is in being pressed or when driven position, shower bath 10 is in high flow rate mode.User presses the button after 46, and auxiliary water circulation flow path 34 is opened, and causes the water yield spraying from outlet nozzle 22 to increase.Secondary controller 42 prevents that the overall flow rate of main water-flowing path 30 and auxiliary water circulation flow path 34 from exceeding a specific flow velocity.Therefore,, in the time that user presses button 46, auxiliary water circulation flow path 34 increases the water yield flowing out from shower bath 10.

In the time of user's release-push 46, auxiliary water circulation flow path 34 is automatically closed under hydraulic pressure (and spring 54, if spring 54 is being installed) effect, and water flow pressure acts on valve member 50, chimeric with movement of valve parts 50 and valve seat 58, thus auxiliary water circulation flow path 34 is closed.Therefore, shower bath 10 is got back to low discharge pattern in the time of release-push 46.(not shown) in other structure, button 46 can adopt various ways move closing between open position (for example slide, laterally slide with respect to handle 14 along handle 14, etc.）

(not shown) in other structure, shower bath 10 can provide two or more flow rate modes (for example low discharge pattern, middle flow rate mode and high flow rate mode).Under such structure, shower bath 10 will comprise multiple water-flowing paths corresponding with flow rate mode similarly.Main water-flowing path will open to provide low discharge pattern.Multiple auxiliary water circulation flow paths will optionally be opened, for example, so that first next-door neighbour's flow rate mode (flow rate mode in to be provided, the flow through flow sum of main water-flowing path and the first auxiliary water circulation flow path), then the flow rate modes (having the flow sum of one or more water-flowing paths subsequently of flowing through) after one or more are provided.Can adopt similarly the mode of valve control to manipulate these flow rate modes.

In the structure illustrating, handle 14(or the housing of button 46 and shower bath 10) flush, to stop shower bath 10 to be fixed under high flow rate mode.Therefore, only, in the time that user has a mind to activation button 46, can " momently " use high flow rate mode.(not shown) in other structure, button 46 can be recessed, lower than the surface of handle 14.

Other shower product of controlling by promotion button or bar conventionally can " be fixed " under high flow rate mode and (for example utilize band or clamping device).Shower bath 10 of the present utility model provides button 46, itself and flush or lower than surface, and only in the time that user has a mind to drive, can activation button 46.In the time of user's release-push 46, shower bath 10 is still got back to low discharge pattern.Button 46, with the flush of handle 14 or lower than surface, can for example be avoided unexpected activation button 46, can also avoid because button 46 is remained on the unfavorable variation that high flow capacity position causes by band, gripping object or other device, etc.

Shower bath 10 can be consumer effective water saving shower pattern is provided, and this water saving shower pattern will temporarily be substituted in the time carrying out specific shower task, thereby of short duration current increment is provided.As previously mentioned, when shower bath 10 is during in low discharge pattern, main jet jet sprays from outlet nozzle 22, that is, and and the water ejection of the main water-flowing path 30 of only flowing through.Main jet jet will drench with minimum water content consumption and warm shower person.In the time that shower person needs the larger water yield (for example, while rinsing shampoo, cleaning shower house etc.), can open auxiliary water circulation flow path 34 by activation button 46, thereby increase the water yield momently.

Common situations be by open simply or closed through hole control double-current fast Handheld shower set with change flow velocity.This class device has its defect, because the change of flow depends on the supply pressure of system to a great extent, therefore, in pressurizing feedwater system and gravity water distribution system, this device cannot fully move.The use of multiple pressure force compensating volume control device, master selector 38 and auxiliary governor 42 as previously described, will all maintain the flow regulating under jet mode, allows shower bath 10 to use in high-pressure water inlet system and gravity feed system.

In the structure illustrating, two kinds of flow rate modes (high flow capacity and low discharge) are realized by increasing auxiliary water route/water-flowing path 34, instead of by two independently between water-flowing path switch realize.In one example, low discharge pattern can provide the flow velocity of the highest 1.4 gallons (gpm) per minute, and high flow rate mode can provide the flow velocity of the highest 2.0gpm.The device with two independent water-flowing paths needs independently low discharge path of high flow capacity path and, and its size can adapt to respectively 2.0gpm and 1.4gpm.On the contrary, in shower bath 10 of the present utility model, master selector 38 allows the flow velocity of the highest 1.4gpm by main water-flowing path 30, simultaneously for the high-velocity flow of the 2.0gpm altogether spraying from outlet nozzle 22 during high flow rate mode is provided, the size of auxiliary water circulation flow path 34 only needs to adapt to the 0.6gpm increasing.The size that this has reduced auxiliary water circulation flow path 34, makes the building block of shower bath 10 be suitable for less packaging.

Because the needed area of auxiliary water circulation flow path 34 is relatively little, thereby it is less to open the needed power of valve member 50.While not pressing button 46, hydraulic pressure will help maintaining valve parts 50 in closed condition.Because hydraulic pressure is for the closed condition of maintaining valve parts 50, therefore dispensable for overcoming the return spring of driving force.As previously mentioned, can use alternatively return spring 54 to affect the needed power of activation button 46.

The optional structure that shower bath 10 shown in Fig. 5 and Fig. 6 contains driving mechanism or button 46 '.The mode of operation of button 46 ' is identical with the mode of operation of above-described button 46 substantially, and the identical Reference numeral using in Fig. 1 to Fig. 4 is for Fig. 5 to Fig. 6, to represent the feature identical with the feature of above describing.

Button 46 ' comprises flexible membrane 60, and preferably, flexible membrane 60 for example, is made with elastomeric material (thermoplastic elastomer (TPE), thermo-setting elastomer) or other suitable flexibility and/or polymeric material.Button 46 ', with the flush of handle 14 or lower than surface, for for example avoiding unexpected driving, is avoided because button 46 ' is remained on the unfavorable variation that high flow capacity open position causes by band, gripping object or other device, etc.(not shown) in other structure, button 46 ' can be recessed, lower than the surface of handle 14.

Especially, film 60 is connected with handle 14 at its outward flange or excircle place.The outward flange of film 60 is fixedly connected with handle 14, to prevent causing unfavorable variation because embedding foreign material between button 46 ' and housing 14 in the time attempting button 46 ' to remain on high flow capacity position.Outer peripheral multiple parts of film 60 comprise groove 62, for receiving the lip limit 64 being formed on handle 14, thereby in the time pressing button 46 ', can make the outward flange of film 60 keep being connected with handle 40.The outer peripheral other parts of film 60 comprise spine 66, and spine 66 is chimeric with the inner surface of handle 14, to prevent that film 60 comes off from handle 14 when the release-push 46 '.In the time that user presses button 46 ', the middle bent of film 60 and form concavity, outward flange keeps fixing with handle 14 simultaneously.In other structure, (not shown) can adopt other structure that the outward flange of button 46 ' is fixed on handle 14.

Button 46 ' is fixedly connected with valve member 50.In the structure illustrating, utilize the ridge 68 of coupling with groove 70, button 46 ' to be fixedly connected with valve member 50.In other structure, (not shown) can adopt other coupling part.

Button 46 as previously described, when button 46 ' is in being pressed or when activation point, shower bath 10 is temporarily in high flow rate mode, until release-push 46 '.For example, by hydraulic pressure and/or spring 54, valve member 50 and film 60 are biased in low discharge mode position.In low discharge mode position, film 60 is relatively smooth, and flushes or approximate handle 14(or the housing flushing in shower bath 10) surface, thereby forbid that shower bath 10 is fixed under high flow rate mode.Therefore, only, in the time that user has a mind to activation button 46 ', can " momently " use high flow rate mode.

As mentioned before, in the time that user presses button 46 ', auxiliary water circulation flow path 34 is opened, and causes the water yield of outlet nozzle 22 to increase.Secondary controller 42 prevents that the overall flow rate of main water-flowing path 30 and auxiliary water circulation flow path 34 from exceeding specific flow velocity.Therefore,, in the time that user presses button 46 ', auxiliary water circulation flow path 34 adds the flow of shower bath 10.In the time of user's release-push 46 ', due to hydraulic pressure (and spring 54, if any) thus to the effect of valve member 50 make valve member 50 move for the chimeric auxiliary water circulation flow path 34 of closing of valve seat 58, auxiliary water circulation flow path 34 is automatically closed.

Therefore, except other aspects, the utility model mainly provides a kind of water-saving apparatus for shower bath 10, the auxiliary water circulation flow path 34 that it has main (low discharge) water-flowing path 30 and optionally drives, auxiliary water circulation flow path 34 supplements to increase by the total flow of shower bath 10 to main water-flowing path 30.Shower bath 10 in accompanying drawing is defaulted as low discharge pattern, and low discharge pattern is the pattern using the most of the time in shower process.In order to complete shampoo cleaning task or other high flow capacity task, flow-control (by button 46 and 46 ') allows temporary transient augmented flow in the situation that manually being activated, and flow-control button 46 and 46 ' release make device get back to low discharge default setting.Described flow-control is anti-tamper, and is not activated in the normality of product is used.Activation must be have a mind to and can only temporarily use.For most of service conditions of shower bath 10, device 10 actual water consumption is lower than maximum that can bearing capacity.

Fig. 3 shows shower head 110, and it has water inlet pipe 114, shower bath body 118, supporting base 122, water outlet jet face 126 and elasticity insert 130, and elasticity insert 130 is between supporting base 122 and water outlet jet face 126.Shown water outlet jet face 126 is made up of transparent material, for example transparent thermoplastic.Insert 130 comprises the nozzle 134 that is formed at insert 130 inside.Nozzle 134 is made into pyramid type through hole.Supporting base 122 comprises through hole 138, and through hole 138 aims to coordinate formation nozzle 134 with nozzle 134.Between water inlet pipe 114 and supporting base 122, form chamber 142, chamber 142 provides the space for the water that flow to water outlet nozzle 134 from water inlet pipe 114 is distributed.

In some structure, can adopt silicon rubber to form insert 130, and insert 130 can be molded between the supporting base 122 of being made up of thermoplastic and water outlet jet face 126.Therefore, supporting base 122 and water outlet jet face 126 can be bonded together by elasticity insert 130.So, illustrated insert 130 can be not only for functional part but also as making supporting base 122 attach to the securing member of water outlet jet face 126.

This has reduced assembly cost in improving flexible design degree.Such design allows to use transparent jet face 126, sees through transparent jet face 126 and can see elasticity insert 130, but do not expose impact spine attractive in appearance, welding node, seam etc.Such design provides a kind of and for the bonding by chemistry and/or physics, clear or translucent water outlet jet face 126 has been attached to the outside method of device 110, thereby has eliminated the needs such as fastening, joint, seam.

Reduced as far as possible the appearance of securing member, joint and pad by multiple other method, this normally realizes by covering, colouring or hiding aesthetic drawback.Adopt covering or obfuscation mode to hide securing member and must use other parts (lid, ornamental layer or film etc.) and/or processing.Above-mentioned fastening method has been eliminated the needs of hiding securing member, in aesthetics design, can freely use transparent or semitransparent jet face 126.In addition, above-mentioned fastening method and structure complete the function of sealing, bonding and/or the formation of injection nozzle 134 substantially in single step.

Elasticity insert 130 machine-shaping with the following methods: elasticity insert 130 stretches out (or exposing through supporting base 122) through supporting base 122, this is conducive to elastic surface as sealing surfaces, be conducive to each water-flowing path to be separated for multi-functional injection head, etc.The method can be utilized insert-molding, repeatedly spray injection moulding etc., also can utilize thermoplasticity injection moulding, LIM or both are mixed, etc.

Fig. 4 schematically shows frock 146, and it is for the manufacture of shower bath, example shower head 110 as shown in Figure 3.Frock 146 comprises the first half module 150 and the second half module 154 that have defined frock surface 158, and frock surface 158 is configured to and just contacts at manufactured product.Such as, add metallic additions (sheet metal, fiber etc.) to one or more substrates 122 ' and 126 ' (supporting base 122 and water outlet jet face 126), for inserting, shifting or repeatedly spray post forming.Metallic additions increases the ability of the thermal energy storage (thermal capacity) of substrate to some extent, and for example, the ability of release energy rapidly (thermal conductivity) increases to some extent for the short vulcanization (sulfuration of insert 130) of silicon rubber 130 ' to make substrate.Therefore, provide the method for one moulded silicone rubber 130 ' between thermoplasticity portion 122 ' and 126 ', silicone does not contact substantially with frock surface 158 in the method.

Current many application adopt the method for post forming that silicone is taken shape in thermoplastic substrate.This provides the permanent bonding between substrate and rubber, and is useful especially for the sealing applications that needs integral sealing.Processing in silicon rubber process, conventionally frock is heated to accelerate the sulfuration of rubber.Because at least one side of silicone is exposed to high temperature frock surface, so can adopt post forming that the thin portion of silicone is molded in plastic section.

As shown in Figure 4, at silastic-layer 130 ', between two thermoplasticity portions 122 ' and 126 ' in the situation that, the insulation characterisitic of thermoplasticity portion suppresses sulfidation.By changing the thermal characteristics of thermoplasticity portion, thermoplasticity portion 122 ' and 126 ' can preserve heat better, and becomes in fact the extension on frock surface 158, not only preserves heat and also heat is delivered to silicone 130 ' from molding frock 146, and be beneficial to sulfuration.

In common way, before post forming, thermoplasticity portion is carried out to preheating, object is to make adhesion characteristics to maximize.But the shortcoming of this method is, the thermal capacity of thermoplastic substrate is on the low side and thermal conductivity is poor.Therefore,, in current techniques, do not allow moulded silicone rubber between two insulating layer and thermoplastic layers.This just requires to make silicone to be exposed at least in part the frock surface of high temperature, so that sulfuration.

C=dQ/m dt (formula 2)

Wherein: dQ is the heat of supplying with,

M is quality, and

Dt is temperature variation.

Following formula is the formula 2 representing with heat dQ:

DQ=m c dt (formula 3)

About formula 1,2 and 3, the method increases available energy (q) by the quality (m), specific heat capacity (c) and the thermal conductivity (k) that increase thermoplastic substrate 122 ' and 126 ', is conducive to accelerated cure.

The additive that is used for improving thermal characteristics also can provide a kind of device for the parts of frock 146 are heated, and perhaps can utilize electromagnetic energy to heat.Before this can eliminate in substrate 122 ' and 126 ' is loaded into frock 146, reply substrate 122 ' and the 126 ' needs that carry out preheating.

The utility model method also can be applicable to repeatedly spray processing technology, wherein can in same frock 146, successively create thermoplastic substrate 122 ' and 126 ', and elastomer member 130 '.The after-heat of thermoplastic molded processing can be kept in substrate 122 ' and 126 ', and can be conducive to the 130 ' sulfuration of follow-up rubber components.
