Throughout the specification, unless the context otherwise requires, otherwise word " including (comprise) " or such as " including The deformation of (comprises or comprising) " will be understood as implying to include the entirety (integer) or overall cluster (group of integers), but it is not excluded for any other entirety or overall cluster.

In addition, throughout the specification, unless the context otherwise requires, otherwise word " including (include) " or such as The deformation of " including (includes or including) " will be understood as implying including the entirety or overall cluster, but not Exclude any other entirety or overall cluster.

Although it is previously noted that this disclosure relates to be generally suitable for use in the piston flushing valve of sanitary equipment, but it is understood that It is that the piston flushing valve is not necessarily limited to this purposes.For example, the piston flushing valve can be suitble to/be suitable for and fluid point It is used together with type consumer machine/apparatus (for example, portable coffee machines, water dispenser etc.).

Fig. 1 a depicts the conventional piston with shell 11, piston component 12, first seal 13 and second seal 19 Flushing valve 10.In general, piston component 12, first seal 13 and second seal 19 can be carried in shell 11.In addition, The shape and size of shell 11 can be set to form intake section 10a and exit portion 10b.As previously mentioned, conventional Piston flushing valve is typically constructed of metal.Specifically, conventional piston flushing valve 10 is made of metal.More specifically, shell 11 It is made of metal.

Piston component 12 may include the first part that can be attached to of nut 14, piston rod 18, first seal 13 with And the second part that second seal 19 can be attached to.In addition, first seal 13 can be contacted with nut 14.Show at one In example sexual orientation, as shown in Figure 1, first part can be the low portion of piston component 12, and second part can be work The upper part of plug assembly 12.

In use, piston flushing valve 10 can be connected to fluid inlet source (not shown) at intake section 10a.Piston punching Fluid hose (not shown) can be connected further at exit portion 10b by washing valve 10.From fluid inlet source fluid (for example, Water) fluid hose for being connected to exit portion 10b can be flowed to via piston component 12 from intake section 10a.

Piston component 12 can be activated, to move in shell 11, to prevent or allow fluid from inlet portion 10a is divided to flow to exit portion 10b.For example, piston component 12 can be according to enabling the piston component in shell 11 along vertical The mode mobile to axis (as shown in arrow 10c) is activated.

Obviously, it is moved in shell 11 with piston component 12, nut 14 may not become in which can avoid as time goes by Pine.Since nut 14 loosens, first seal 13 (it is contacted with nut 14) may also fluff.When piston flushing valve 10 is using When middle (that is, during fluid flows to exit portion 10b across piston component 12 from intake section 10a), there may be small for this Vibration.In addition, since fluid travels across fluid hose, this microvibration produced may be amplified, to generate hammering Noise.

Fig. 1 b shows the associated various products form (10d, 10e and 10f) of the piston flushing valve 10 with Fig. 1 a.As schemed Show, product form is integrated design form.

Fig. 2 a shows piston flushing valve 20 according to the one side of the disclosure.Preferably, piston flushing valve 20 is suitable for Sanitary equipment (not shown).Piston flushing valve 20 can be further adapted for/be suitable for and portable fluid dispensation machines/equipment (for example, portable coffee machines) are used together.

Piston flushing valve 20 includes shell 21, piston component 22, primary seal 23 and auxiliary sealing member 29.Piston component 22 Including nut 24 and piston rod 28.Preferably, shell 21 is made of plastics.It is highly preferred that shell 21 is made entirely of plastic.

Shell 21, piston component 22, auxiliary sealing member 29, nut 24 and the piston rod 28 of Fig. 2 a can it is certain but not All aspects are analogous respectively to shell 11, piston component 12, second seal 19, nut 14 and the piston rod 18 of Fig. 1 a.

In this regard, the relevant portion for being previously with regard to the discussion of Fig. 1 a can be applied similarly to Fig. 2 a.In an example In, as shown in Figure 2 a, the shape and size of shell 21 can be set in the way of so as to loading piston component 22.Another In a example, piston flushing valve 20 may include being connected to the intake section 20a of fluid inlet source (not shown) and being connected to stream The exit portion 20b of body pipe (not shown).

It can at least be existed with the conventional piston flushing valve 10 of Fig. 1 a according to the piston flushing valve 20 of embodiment of the present disclosure It manufactures different on the material of shell 21 (according to fig. 2) and the material of manufacture shell 11 (according to Fig. 1).Specifically, 21 (root of shell According to Fig. 2) it is made of plastics, and shell 11 (according to Fig. 1) is made of material (that is, metal) besides plastic.

In addition, according to the piston flushing valve 20 of embodiment of the present disclosure can with the conventional piston flushing valve 10 of Fig. 1 a to It is few different in sealing arrangement structure.This is discussed in further detail below with regard to Fig. 2 b.

Fig. 2 b shows piston flushing valve 20 when in use and may be at open configuration 30a or closed configuration 30b.

In general, piston component 22 can be activated, make it possible to first position in shell 21 and the second position it Between move.For example, piston component 22 can axis (for example, as shown in arrow 20c of Fig. 2 a) be mobile along longitudinal direction in shell 21, So that piston flushing valve 20 is in one of open configuration 30a and closed configuration 30b.

The shape and size of shell 21 can be further set such that opening portion 31a can be limited at inlet portion Divide between 20a and exit portion 20b to allow fluid from intake section 20a when piston flushing valve 20 is in open configuration 30a Flow to the mode of exit portion 20b (that is, as shown in direction arrow 31b).Opening portion 31a may include that shape and size can quilt It is set as carrying the edge portions 31c of primary seal 23.In this regard, it is believed that primary seal 23 is by along opening portion The edge of 31a carries.

Moreover, in open configuration 30a, it will be appreciated that, piston component 22 is mobile far from primary seal 23, to allow Fluid flows to exit portion 20b from intake section 20a (as shown in direction arrow 31b).On the contrary, in closed configuration 30b, it can To understand, the adjacent primary seal 23 of piston component 22 with blocking/closing opening portion 31a and prevents fluid from intake section 20a flows to exit portion 20b (as shown in direction arrow 31d).

In this regard, piston component 22 can be activated, so as to adjoining (that is, substantially completely contacting) primary seal The mode of 23 (that is, closed configuration 30b) or separate primary seal 23 (that is, open configuration 30a) is mobile.

In one embodiment, when being in open configuration 30a, piston component 22 may be located remotely from the shifting of primary seal 23 It is dynamic, so that still having localized contact between piston component 22 and primary seal 23.However, it is possible to understand, this part Contact does not prevent fluid from flowing to exit portion 20b from intake section 20a.

In another embodiment, when being in open configuration 30a, piston component 22 may be located remotely from the shifting of primary seal 23 It is dynamic, so that not contacted between piston component 22 and primary seal 23.

Therefore, in the context of the exemplary orientation in Fig. 1 a more early discussed, similar to the conventional design of Fig. 1 a Auxiliary sealing member 29 can be attached to the upper part of piston component 22.However, the wherein first seal 13 with Fig. 1 is attached to The conventional piston flushing valve 10 of piston component 12 is compared, and primary seal 23 is not attached to piston component 22.On the contrary, primary seal 23 (for example, being made of rubber) are positioned at the base portion (that is, edge portions 31c) of intake section 20a, and effect is when piston group Part 22, which is moved to close when being limited at the opening portion 31a between intake section 20a and exit portion 20b, makes any fluid Flowing stops.In other words, primary seal 23 is maintained at fixed position relative to the movement of piston component 22 in shell 21 (that is, primary seal 23 is not moved together with piston component 22 and nut 24).In this regard, it is believed that primary seal 23 is in work The mobile period of plug assembly 22 and shell 21 are kept fixed relationship.

More specifically, primary seal 23 can fixedly be carried in shell 21.More specifically, primary seal 23 can be with It is carried in shell 21 in fixed and stable mode, so that primary seal 23 is still in shell although piston component 22 is mobile It is held in place substantially in body 21.Therefore, in the mobile period of piston component 22, primary seal 23 is considered and its surrounding objects (that is, in shell 21) is kept fixed relationship.

In this regard, it will be appreciated that, it is associated according to the piston flushing valve 20 with Fig. 2 of embodiment of the present disclosure Sealing arrangement structure can be different from the sealing arrangement structure of conventional piston flushing valve 10.

Clearly as primary seal 23 substantially reduces a possibility that fluffing (that is, since piston component 22 is mobile), produce A possibility that stating microvibration and/or hammering noise before death will significantly reduce.Primary seal 23 can be by propylene diene Monomer (EPDM) rubber or nitrile rubber (NBR) are made.

In addition, as mentioned above, piston flushing valve 20 (i.e. Fig. 2) can be with conventional piston flushing valve 10 (i.e. Fig. 1 a) no Together, this is because the shell 21 of piston flushing valve 20 is made of plastics (it is highly preferred that being made entirely of plastic), and conventional piston The shell 11 of flushing valve 10 is made of metal.Obviously, as previously discussed, etching problem associated with conventional piston flushing valve It can be greatly reduced.

According to embodiment of the present disclosure, nut 24 may include the movement for guiding piston assembly 22 in shell 21 Multiple flanks 25 of (that is, movement between open configuration 30a and closed configuration 30b).In addition, piston component 22 can be wrapped also Plastic filter (strainer) 26 is included, which, which plays, prevents unwanted material (such as grains of sand) from entering piston flushing valve The effect of 20 filter device.Plastic filter 26 can (for example) be positioned/be placed in the second part (example of piston component 12 Such as, upper part) at.

The piston that Fig. 3 shows a part as modularization flush valve assembly according to another aspect of the disclosure rinses Valve 20.Preferably, piston flushing valve 20 can be according to embodiment of the present disclosure for example for executing defending for flushing movement A part of the modularization flush valve assembly of generating apparatus.In this regard, it is believed that modularization flush valve assembly includes piston punching Wash valve 20.

Preferably, for use, modularization flush valve assembly can be the flush valve assembly of customizable type.It is specific and Speech, piston flushing valve 20 (more specifically piston component 22) can be a kind of or more according to enabling the piston flushing valve to be based on The mode that kind construction is operated neatly is controlled.In this regard, modularization flush valve assembly is considered customizable Modularization flush valve assembly because piston component 22 can be controlled neatly to be grasped based on one or more constructions Make, as being discussed in further detail below with regard to Fig. 7.

Modularization flush valve assembly may include the lid 32 (for example, top cover) with screw 33.Modularization flush valve assembly It can further include actuator 38.As shown, lid 32, actuator 38 and piston flushing valve 20 can be carried by shell 21.Specifically For, piston component 22 can be carried in shell 21, and lid 32 and actuator 38 can be carried on outside shell 21.

A part of shell 21 in Fig. 3 is locally removed, can to show primary seal 23 and piston component 22 To be carried in shell 21, and can be configured to differently position relative to each other.In one embodiment, master is close Sealing 23 does not contact (that is, when in open configuration 30a) with piston component 22.

In general, piston flushing valve 20 can be connected to lid 32 and actuator 38.More specifically, piston component 22 can join It is connected to lid 32 and actuator 38.

As mentioned above, lid 32 can have screw 33.Screw 33 can be used to implement the small of fluid drainage rate Adjustment.This is discussed in further detail below with regard to Fig. 4 and Fig. 5.

Actuator 38 can be operable to for controlling piston flushing valve 20.Specifically, actuator 38 can be operated To control piston component 22, so as to piston flushing valve 20 can according to enable the piston flushing valve with one or more constructions The mode operated is neatly controlled.This is discussed in further detail below with regard to Fig. 7.

With reference to Fig. 4 and Fig. 5, modularization flush valve assembly can be connected to plug valve 35 by joint member 34.Pipe fitting 36 One end of plug valve 35 can be connected to and executor 37 can be connected to the other end of plug valve 35.Pipe fitting 36 can connect It is connected to fluid (for example, water) supply pipe (not shown).Executor 37 can be used for controlling the opening and closing of plug valve 35.This Outside, plug valve 35 can accommodate the anti-rainbow for preventing the fluid from modularization flush valve assembly back to fluid supply tube mobile Inhale mechanism (not shown).

In addition, Fig. 4, which shows actuator 38, can be connected to piston flushing valve 20 for example, by the mode of flexible wires 39.Actuating Device 38 may, for example, be the form with multiple pushbuttons for pushing part, such as further detailed below with regard to Fig. 6 It discusses.

In addition, as an option, as shown in figure 4, modularization flush valve assembly can further include sensor (not shown) With the Electromechanical solenoids 40 with solenoid coil 41.Sensor can be connected to sensor controller (not shown).Electromechanical spiral shell Spool 40 can be connected to piston flushing valve 20.Electromechanical solenoids 40 can be connected to sensor control by conductor jointer 42 Device, the sensor controller can be configured to supply electric energy to operate solenoid coil 41 and therefore operate Electromechanical solenoids 40.Pushbutton and sensor may be respectively used for piston flushing valve 20 manually boot/activate and starting/actuating automatically, As being discussed in further detail below with regard to Fig. 7.

In addition, as another option, as shown in figure 5, modularization flush valve assembly can not include Electromechanical solenoids 40. Instead of Electromechanical solenoids 40, flow path sealing element 43 can be set to prevent undesirable fluid from leaking.This will with reference to Fig. 7 into One step is discussed in detail.

Fig. 4 and Fig. 5 will be below for realizing quilt in the context of the screw 33 of (smaller) adjusting of fluid drainage rate It discusses.

Fig. 4 shows the screw 33 (position of screw 33 with reference to shown in Fig. 5) being adjusted downward, and Fig. 5 shows and is in The screw 33 (position of screw 33 with reference to shown in Fig. 4) for the position being adjusted up.In upward position (according to Fig. 5) The adjusting of screw 33 can be associated with increased fluid (for example, water) rate of discharge.Spiral shell in down position (according to Fig. 4) The adjusting of nail 33 can be associated with reduced fluid (for example, water) rate of discharge.

In general, piston component 22 can be adjusted accordingly, because of piston component 22 and primary seal by adjusting screw 33 Isolated degree between part 23 can be controlled when being in open configuration 30a.Specifically, by adjusting screw 33, it is living Plug assembly 22 can be adjusted accordingly far from the mobile distance of primary seal 23 when being in open configuration 30a.Obviously, Piston component 22 be allowed to far from primary seal 23 it is farr mobile, the fluid drainage rate allowed is higher.On the contrary, piston group Isolated degree between part 22 and primary seal 23 is more restricted, and the fluid drainage rate allowed is lower.

In the above described manner, it will be appreciated that, the fluid drainage allowed can be controlled by way of adjusting screw 33 Rate.Furthermore it is possible to understand, is considered to the control for the fluid drainage rate allowed showing for the mobile control of fluid Example.

It is also contemplated that arriving, another example of the mobile control of fluid can be the side by controlling fluid flushing volume Formula.In addition, as mentioned above, actuator 38 can (for example) be the form with multiple pushbuttons for pushing part. These are discussed in further detail below with regard to Fig. 6 a and Fig. 6 b.

It can have there are two the form for the pushbutton for pushing part that Fig. 6 a and 6b, which show actuator 38, Linear activated power is provided in piston flushing valve 20.In this regard, actuator 38 can be associated with double pre-washing functions.Some In embodiment, actuator 38 may include actuator 38 being maintained at extended position piston flushing valve 20 is not activated Contained spring (not shown).When pulled, flexible wires 39 linearly convert pulling force, following 38 (i.e. pushing position of hydraulic actuator Set), to start piston flushing valve 20.When the pulling force in flexible wires 39 is released, actuator 38 is back by contained spring The reset condition (i.e. extended position) of its position.

Actuator 38 may be coupled to plunger (push plunger) 62, which is pushed away according to which part of actuator 38 It moves and is engaged with the pressure of variation with the piston rod 28 of piston component 22, and therefore select rinse mode to realize desired stream Body flush volume.Screw 63 can be arranged for adjusting the angle of plunger 62.

For example, cause rotating lever 64 to rotate when screw 63 rotates clockwise, so that the angle of plunger 62 is promoted, This can increase the volume of fluid flushing.Alternatively, when screw 63 rotates counterclockwise, cause rotating lever 64 along Xiang Fanfang To rotation, to reduce the angle of plunger 62, this can reduce the volume of fluid flushing.Therefore, with the precision level list of 0.1mm Solely two promotion parts of adjustment (that is, each promotion part can be independently adjusted) is possible.

Therefore, it will be appreciated that, the example of the mobile control of fluid may include to the fluid drainage rate and stream allowed Body flush volume is controlled.The other examples of the mobile control of fluid may include preventing and/or allowing fluid in intake section It is flowed between 20a and exit portion 20b, as discussed in earlier in respect of figures 2.

Obviously, for example, by following manner:

1) the fluid drainage rate allowed is controlled,

2) fluid flushing volume is controlled, and/or

3) it prevents and/or fluid is allowed to flow between intake section 20a and exit portion 20b,

Piston flushing valve 20 can be operated in the way of to control fluid movement.

Mentioned above, modularization flush valve assembly is considered customized modularization flush valve assembly, because It can neatly be controlled for piston flushing valve 20 to be operated based on one or more constructions.This is below with regard to Fig. 7 It is discussed in further detail.

With reference to Fig. 7, a variety of constructions (that is, construction option) are possible.Every kind of construction can be with one or more component phases Association.In one example, construction option 1 is associated with the combination of component 1 and component 2.In another example, option is constructed 5 is associated with the combination of component 3, component 4 and component 2.

At least one control module (not shown) associated with one or more construction options can be set, and can Operation is for controlling piston flushing valve 20.Control module can pass through one or both of hardware realization and software realization Mode is realized.In one example, control module can be hardware module (that is, hardwired, mechanical part and/or discrete Electronic sensor component) form.In another example, control module can be the shape of integrated circuit modules by programming Formula.

One or more control modules may be mounted in modularization flush valve assembly.Specifically, one or more controls Molding block can be carried by shell 21.Actuator 38 can be connected to one or more control modules, which again can be with It is connected to piston flushing valve 20.In this regard, actuator 38 can be connected to piston flushing via one or more control modules Valve 20.

By the appropriate operation of actuator 38, it can star one or more desired construction options.Specifically, actuating Device 38 can be operable to starting (multiple) control module to operate piston flushing valve 20.More specifically, actuator 38 can Be operable to starting (multiple) control module, so as to based on (a variety of) construction options associated with (multiple) control module come Operate piston flushing valve 20.

In one example, the operation of actuator 38 can be by manually booting (such as with reference to discussed in fig. 4 to fig. 6 Manually push starting) mode.In another example, the operation of actuator 38 can be by way of starting (at this automatically In the case of kind, actuator 38 can be the shape of electronic sensor (such as motion sensor, optical sensor or optical sensor) Formula).In yet another example, the operation of actuator 38 can be manually booting and automatically by way of both startings (this In the case of, actuator 38 can be with the combined mould for pushing actuating section (such as button) and sensor actuating section manually The form of block).

Therefore, piston flushing valve 20 can be activated by way of one or both of manually and automatically.It causes manually It is dynamic to be completed by Client-initiated process, conventionally by the interaction with mechanical handle.Automatic actuating is by using biography When sensor, which exists and activate piston flushing valve when not needing Client-initiated to determine user, is completed, such as when When user has completed the use of equipment.

Preferably, actuator 38 can be associated with one or more operation modes.One or more operation modes can be with Including sensor starting, the starting of contact manual user and/or remote manual user starting.

Obviously, a kind of mode of actuating piston flushing valve 20 is started by push type manually, wherein can (for example) lead to It crosses by hydraulic actuator 38 and starts flushing.As mentioned by earlier in respect of figures 4, actuator 38 may include (for example) two promotions Part.First pushes part to may be used to provide whole rinse modes, and second pushes part to may be used to provide part punching Mold cleaning formula.Each promotion part can be activated independently of one another.Button 38 can have more than two and push part, wherein often A promotion part can be associated from different rinse modes.
