Detailed description of the invention

Hereinafter, will coordinate accompanying drawing and element numbers that some exemplary embodiment of the present invention is described in detail； Wherein, the present invention is not described for all of exemplary embodiment.It is true that what the present invention was described and illustrated at this The scope of the present invention, application or configuration can not be caused restriction by example；Otherwise, the present invention provides those exemplary embodiments Purpose essentially consist in and enable the content of this specification to meet applicable legal provisions.In this manual, identical assembly The assembly that symbology is identical.Additionally, "or" one word as used herein should be read as logical operator, with appointing of being connected at it One or more computing body obtains the result set up when setting up.Here, operation couples and should be understood direct or non-immediate company Junction relationship, and in both cases, all makes to operate mutually between the assembly coupled and is functionally interconnected.

Here, some exemplary embodiment of the present invention provides the improvement design of a Sprinkler.Those exemplary realities Execute one or more strategic locations that compensating part can be arranged in the main body of this Sprinkler by example, with protect this position and The assembly of this position adjacent.This compensating part provided or this device can have can make this compensating part be maintained in this device The feature of tram.

Fig. 1 is the block chart showing the Sprinkler 10 according to the present invention one exemplary embodiment.Modular watering dress Put 10 and can include main body 20, operating parts 30 and a shower nozzle 40.Main body 20 is available for an operator and holds along one part Hold.In some cases, this partially defined grip portion 22 of main body 20 that can grip, and this grip portion 22 can be set Between an export department 24 and an inlet portion 26.Main body 20 can accommodate a flow cavitation result assembly 50, this flow cavitation result assembly 50 It is configured so that Sprinkler 10 performs a control function relevant to the current by Sprinkler 10 (for example, from entering Oral area 26 flow to the current of export department 24).

In certain embodiments, flow cavitation result assembly 50 can include on-off control assembly 52 and a flow-control group Part 54.Operating parts 30 can be connected to main body 20 to interface with flow cavitation result assembly 50, thereby according to the position of operating parts 30 Alternately start and stop to flow through the current of Sprinkler 10.Therefore, in some cases, operating parts 30 can be in flow cavitation result group Part 50 is turned on and off a valve body or the operating assembly of other flow cavitation result assemblies as (partially or fully).Operating parts 30 is outstanding It can interface with the on-off control assembly 52 in flow cavitation result assembly 50.In some cases, flow cavitation result assembly 50 is permissible There is a flow control function further, so that it more can be right according to the control of operator beyond open and close current Water flow does a certain degree of regulation.Flow control assembly 54 can be an example of the structure performing above-mentioned functions.But, Flow control assembly 54 can also be omitted in some examples.When Sprinkler has flow control function, can pass through Flow control assembly is operated by one flow control member 60, and this flow control member 60 can be the body of rod, button, regulation Dish or other be available for operator and adjust the assembly of water flow.

Shower nozzle 40 can be connected to the export department 24 of main body 20, sprays with the sprinkling characteristic according to shower nozzle 40 and flows through shower nozzle The water of 40.In some cases, shower nozzle 40 can be a shower nozzle selected from a number of multiple different shower nozzles, and institute The each stated in different shower nozzle all has different structures and/or configuration, to deal with different sprinkling demands or expectation.

Main body 20 can have or accommodate the runner extending to export department 24 from inlet portion 26.On-off control assembly 52 And flow control assembly 54 can be arranged in runner, runner to be divided into space or the region of uniqueness.Water may Any one collected in described region, and can freeze or pressure pulse situation occur time it is caused damage. For example, when water is frozen, its can the region of the described uniqueness of runner and arround the tool that defined of the assembly of cincture Have in the space of fixed volume and produce volumetric expansion (that is, internal functional assembly).Pressure therefore can be at the sky of fixed volume Increase between, and when pressure increases to enough values, the runner tube wall of water the most likely can rupture, or more likely causes The damage of internal functional assembly.

As it has been described above, therefore these regions being substantially affected can be considered " key area ", and described key area Territory can include the entrance area between inlet portion 26 and on-off control assembly 52, be positioned at on-off control assembly 52 and flow Control the zone line between assembly 54 and the exit region between flow control assembly 54 and export department 24.In order to Protecting above-mentioned region to be protected from damaging, an exemplary embodiment can arrange compensating part in each key area.Certainly, Owing to some embodiment may will not have all component of flow control assembly 50 (for example, it is possible to omit flow control assembly 54), some embodiment may only have two key areas.But, in this manual, it should be appreciated that " key area " word Container, space should be considered or be formed adjacent to other districts of runner near the internal functionality assembly of Sprinkler 10 Territory.Additionally, in this manual, internal functionality assembly can include flow cavitation result assembly 50 and shower nozzle 40 (such as, nozzle Part) assembly.

Described compensating part may be used for avoiding because of moisture in key area because freezing or the pulse that is under pressure is caused Expansion and the infringement that causes.For in this regard, such as, compensating part can be inserted in described key area, to provide A kind of under normal operation situation, do not interfere with or disturb the current flowing through Sprinkler 10, but (or compensation) can be contained Residue in volumetric expansion or the assembly of other influences power that the water in key area is caused.Particularly, cause freezing when water During volumetric expansion, this compensating part can stably experience volume contraction, and this compensating part provides the volume contraction of an appropriate amount To compensate any volumetric expansion of moisture.Very and, this compensating part can have enough elastic force with provide under multiple circulations formed There is not the protection of degraded in the material of this compensating part.

Based on this, such as, compensating part by deflection and/or have resilient material and make, thus can not made Compressing and expanding repeatedly is absorbed under conditions of becoming permanent deformation.Therefore, compensating part can be made up of compressible material, Make compensating part can be compressed in key area, thereby freezing or in the pulsation increase key area of water corresponding to water Dischargeable capacity, to avoid the internal functionality assembly of Sprinkler 10 to be damaged.In some cases, compensating part can be by can The material of compression is formed as the cylinder of hollow, and described compensating part can be placed in key area and become compressible structure Part, thereby makes the dischargeable capacity of key area at least increase by 10%.Therefore, compensating part can contain or compensate by the water freezed The volume of the increase caused.In some cases, compensating part can have enough compressibilities, so that key area Dischargeable capacity at least increases by 25%.

In some cases, compensating part can be by as made by the elastomer of thermoplastic elastomer (TPE).Compensating part can have Multiple confining gas spaces (such as, bubble), described confining gas space is formed and is distributed in the volume of whole compensating part. Therefore, described compensating part wherein can be had made by the rubber of multiple hollow enclosed slot room, expanded material by a kind of being similar to. Confining gas space (that is, hollow enclosed slot room) can be fluid-tight structure.These confining gas spaces can be compressible Structure so that compensating part is compressible structure, thereby allow water expansion of being caused when forming ice.The volume of water Increase (that is, volumetric expansion) therefore to be compensated by the volume compression of corresponding compensating part.Then, when ice cube dissolves, envelope Body space of holding one's breath is expanded so that compensating part can carry out volume when moisture converts back liquid and takies less volume swollen Swollen.It should be noted, although multiple CABs can be distributed in the material of similar foaming, and some embodiment can also use Have minority or only a compressible gas compartment if rubber or other bendable material are as compensating part.

Fig. 2 is the exploded view of display Sprinkler 100, and it is an example of the Sprinkler 10 shown in Fig. 1.Watering dress Putting 100 and include a main body 110, it is an example of the main body 20 shown in Fig. 1.Meanwhile, main body 110 has an export department 112 and an inlet portion 114, it is respectively the export department 24 shown in Fig. 1 and the example of inlet portion 26.Inlet portion 114 has There is the threaded connection that can engage with a quick coupling joint 116.On the other hand, export department 112 can be configured to One selected in multiple shower nozzles closely cooperates.Shower nozzle 120 is a kind of specific example of the shower nozzle 40 shown in Fig. 1, and is One of them of the multiple shower nozzle that can engage with export department 112.

Main body 110 can by molded plastics, composite, metal or any other there is sufficiently rigid applicable material and Make, and can be formed as accommodating and define runner (or the water allowing water be able to flow to from inlet portion 114 export department 112 Passage) component, parts and/or assembly.Runner can extend along an axis 118 of a grip portion 119 of main body 110.Only, In certain embodiments, export department 112 can be arranged along export department's axis 113, so that export department 112 is relative to axis 118 Between there is an angle.Furthermore, it is possible to select different agent structures to the different angles defining between axis 118 from axis 113 Degree.

Connecting portion 132 can be arranged on the rear portion of grip portion 119, to receive a cover assembly 150.At Sprinkler 100 Being configured to comprise in the example of flow-control, flow-control bar 162 can be arranged on the acceptance division 160 of cover assembly 150 In.But, in certain embodiments, cover assembly 150 can not have acceptance division 160, does not the most have flow-control bar Not 162 (or not there is any flow control assembly 54).

In one exemplary embodiment, trigger member 140 can be an example of the operating parts 30 shown in Fig. 1.At some In situation, inlet portion 114 and axis 118 and the intersection of axis 113 that trigger member 140 can be pivotally attached in main body 110 Between.In the illustrated example shown in fig. 2, the pivoting point of trigger member 140 is positioned in trigger member 140 corresponding or close inlet portion 114 One end.Only, it is noted that pivoting point (that is, can also be made pivoting point be positioned at by the other end being alternatively arranged at trigger member Intersection near axis 118 with axis 113).One end relative with pivoting point in trigger member 140 can be by alternately towards master Body 110 compresses, and can in the past away from main body 110 direction extend, thereby adjust on-off control assembly 52 be separately turned on Close Sprinkler 100.

Fig. 3 shows the sectional view of the Sprinkler 100 in Fig. 2.Fig. 3 shows that water flow to export department from inlet portion 114 112 runners flowed through.In this example, runner can have multiple key area, and such as one entrance area 200 and goes out Port area 210.Exit region 210 typically can have a zone line 220.

In some cases, entrance area 200 can be considered the region of most critical.Entrance area 200 may be located at into Between oral area 114 and on-off control assembly 52.On-off control assembly 52 can be a gate valve or other (that is, open opening or closing Open or close) between the binary valve of switching, and in some cases, be not particularly suited for throttling or the flow of regulation current.According to This, the water that entrance area 200 would generally be pressed is filled up (such as, when faucet is opened), or, by pressing and (particularly having when leaking of minimum degree when system) is because being locked in the valve of faucet and the valve of on-off control assembly 52 The water nevertheless suffering from pressure to a certain degree between Men fills up.Accordingly, owing to the most usually not discharging the pipe of pressure Road, have freeze or pressure pulse situation occur time, it is more difficult to ease off the pressure when there is no compensating part.

Export department can be arranged between the nozzle of shower nozzle 120 and on-off control assembly 52.But, in some embodiment In (such as, especially in the embodiment including flow control assembly 54), export department can be divided into one first outlet area Territory 210 and one second exit region 220, wherein, the first exit region 210 is nozzle and flow-control group at shower nozzle 120 Extend between part 54, and the second exit region 220 is to extend between on-off control assembly 52 and flow control assembly 54.

First, about the first exit region 210, if the shower nozzle 120 of Sprinkler 100 has open nozzle, and When nozzle is located exactly at the angle allowing the current of all or big portion dry, the aquiform stool in the first exit region 210 can be outwards Flow.But, when Sprinkler 100 is just unfavorable for water therein from hose reel or the angle hung from other devices Flow out, be positioned in the position held water within the first exit region 210 when flow control valve, and/or when nozzle close to During closedown, aquiform stool can rest in the first exit region 210.Additionally, when nozzle is opened slightly, cold air is easy to by One exit region 210 enters so that be susceptible to the phenomenon freezed in the first exit region 210.

Second exit region 220 may be located between the valve of on-off control assembly 52 and flow control assembly 54.At certain In a little situations, the second exit region 220 can be considered the region of the second key, because when on-off control assembly 52 is assumed to be pass The state closed, and when flow control assembly 54 is almost in the state closed, and/or when the angle of Sprinkler 100 is unfavorable for When water therein flows out, the second exit region 220 ability of its pressure release when freezing situation and occurring is next to the lowest region. But, as it has been described above, in the embodiment not comprising flow control assembly 54, this region just can be excluded, or can be with First exit region 210 merges.

In one exemplary embodiment, each key area (that is, entrance area the 200, first exit region 210, and (as applicable) the second exit region 220) can include or can be as at least one compensating part acceptance division.Consequently, it is possible to Described key area is respectively formed as receiving at least one compensating part.Due in some cases, in a key area Multiple compensating part can be provided with, it should be mentioned that, described key area can also be formed as or include one or more benefit Repay part acceptance division.

Fig. 4 includes Fig. 4 A, Fig. 4 B and Fig. 4 C, which show the compensating part of the exemplary embodiment according to the present invention Schematic diagram.Fig. 4 A shows a part for the compensating part 300 according to the present invention one exemplary embodiment and key area The three-dimensional exploded view of inner periphery 310, this diagram is to carry out section along the axis direction of compensating part Yu key area and obtains View.Fig. 4 B is the sectional view of display compensating part 300, and it is obtained along the rectilinear profiles of the axis being perpendicular to compensating part 300 View.Fig. 4 C shows and obtains the sectional view at compensating part 300' with at least one cyclic rib 340' along this axis direction. Fig. 4 D shows the alternative view of the alternate design in the assembly shown in Fig. 4 A.Wherein, Fig. 4 D shows compensating part 300 " with And the fixing rib on key area.Fig. 4 E is that display provides substituting compensating part 300' " the vertical view of another exemplary embodiment Figure.

About Fig. 4 A, compensating part 300 can have generally hollow cylinder, and key area can be big in runner Cause the column part for hollow.Therefore, in most basic embodiment, compensating part acceptance division 320 may simply be in runner There is a part (such as a, part for the tube body of runner) for length that is enough accommodating or that receive compensating part 300.So, Compensating part acceptance division 320 may simply be a part substantially identical with the length of a compensating part in runner.Compensating part receives Portion 320 need not be defined by any other special feature.It should be noted that compensating part 300 is the most all It is necessary for hollow cylindrical.For example, in certain embodiments, compensating part can have any current that can allow at runner The shape of middle flowing, and have and can be maintained at compensating part in runner to bear the shape of volume contraction when necessary.Cause This, in certain embodiments, compensating part can have the shape of half hollow circular cylinder (such as, with the shape shown in Fig. 4 A The shape matched, replaces a part for the whole compensating part 300 of display in Fig. 4 A), or any other suitable shape.

In certain embodiments, compensating part 300 can have an an interior diameter d1 and overall diameter d2.This compensating part 300 Can have length L (that is, along axis direction), on the other hand, the inner periphery of key area 310 can have a diameter d3.In some cases, diameter d3 can be slightly less than diameter d2.Consequently, it is possible to compensating part 300 is being housed into compensating part reception During portion 320 need to by slight compression, and put on the strength on compensating part 300 by the inner periphery of key area 310 should enough energy When current are by runner, compensating part 300 is fixed, or enough can be inserted into Sprinkler (such as, watering at compensating part 300 Device 10 or 100) assembling process in compensating part 300 is fixed.

In some cases, the processing procedure manufacturing compensating part 300 can produce a size range.This benefit is manufactured by general Repaying part, d2 is more than d3, and therefore many compensating parts can be fixed on key area 310 (need or need not compression) closely.So And, some compensating part still may need the outside diameter d 2 in inner loop week diameter d3 slightly larger than key area 310.When it still may be used With provide accommodate at least 10% cubical expansion with compensate freeze situation time, these less compensating parts remain and can use 's.Very and, in fact described in less compensating part can not move axially with being squeezed in this runner (such as, due to And minimized friction between key area 310 inner periphery or without friction).Similarly, in fact the inner periphery of key area 310 is not Need any feature of construction to go physically construction compensating part acceptance division 320 to produce to adapt to about unessential System Component Design Different lengths.Briefly, this system is configured to receive the tolerance of the most a little amount about this compensating part size.

As shown in Figure 4, when being not provided with compensating part, runner can be defined by the inner periphery of key area 310.So And, when compensating part 300 is inserted into compensating part acceptance division 320, runner is by hollow centre region institute circle of compensating part 300 Fixed.Additionally, when water freezes in runner, the volume of water can increase (e.g., about 10%), the diameter of runner therefore can be forced to increase Add.As it has been described above, compensating part 300 is compressible component, so that interior diameter d1 can extend and accommodate after water expands and increased The volume added.If it occur that overall diameter d2 is less than the diameter d3 of key area 310 inner periphery, the water that the most a little (lacking) measures flows through this Between inner circumferential leg and this compensating part outside of key area 310, may then understand be this outside diameter d 2 be likely to because Water expansion between the inner circumferential leg and compensating part outside of key area 310 and reduce.Therefore, this compensating part can be directly Direction, footpath is compressed outward or inward.

Although compensating part acceptance division 320 need not be defined by physical features, in some cases, compensating part acceptance division 320 can have extra feature, such as, be configured to for runner be maintained at by compensating part 300 for fixing arranging The feature of location.In some cases, compensating part acceptance division 320 can be configured to have fixing rib 330, described fixing rib edge The inner periphery of key area 310' in the upper extension of an axial direction (that is, being parallel to the direction of the longitudinal length of runner).Only, make For the scheme substituted, fixing rib can also have ring-type shape (as shown in the dotted line of rib 330'), and it can be around runner Inner periphery extend, and be positioned in the plane being approximately perpendicular to axial direction.Additionally, in some cases, annular ring is permissible It is arranged at each longitudinal end of compensating part 300, thereby defines the length of compensating part acceptance division 320, and limit compensating part 300 movements in the axial direction.

It should be noted that in addition to fixing rib is arranged in runner to define compensating part acceptance division, can also be by solid Hold rib to be arranged on the neighboring of compensating part itself.Fig. 4 D show longitudinal extension fixing rib 340 an example, wherein, Gu Holding rib 340 is along compensating part 300 " neighboring arrange.Although fixing rib 340 be along compensating part 300 " whole length prolong Stretching, fixing rib 340 extends to whole length the most not necessarily.Therefore, fixing rib 340 can extend only to compensating part 300 " A part for length, or fixing rib 340 has relatively small feature (such as, protruding or projection), this little feature can be by It is configured to a straight line or ring-shaped to constitute this fixing rib.In some cases, multiple this kind of fixing ribs 340 can be parallel to each other Ground repeats to extend.Very and, in some cases, the main part of this compensating part 300 can have the diameter d2 less than diameter d3, but It it is the possible effective overall diameter that this compensating part 300 being at least same as or more than diameter d3 is set of this fixing rib 340.Therefore, mend Repay part 300 itself to be not required to be compressed and be easily installed at compensating part acceptance division 320, and only fixing rib 340 may It is compressed into and can be suitably fitted to compensating part acceptance division 320.

Additionally, Fig. 4 C shows the embodiment that ring-type fixing rib 340' extends, this fixing around compensating part 300' outside Rib 340' can be arranged on a part of compensating part 300' and have a distance with its axial end portion；But, hold rib 340' End can also be arranged on or close to end.It should be noted that more than one figure can be included in certain embodiments The multiple example of the fixing rib shown in 4C and Fig. 4 D.Therefore, it can by shown fixing rib with required number of times replicate (or Person is with any required combination), so that multiple fixing rib (identical or different kind) can be provided with in some cases.Similar Ground, uses the fixing rib (e.g., fixing rib 330 and 330') of kind and quantity described in compensating part 320 can also change into list Solely use or (the fixing rib (e.g., 340 and 340') of 300' or 300 ") combines with being located at compensating part.Additionally, in some cases, " surface of alternative one can arrange at least one groove, and this groove for compensating part acceptance division 320 or compensating part 300/300'/300 Can be configured to accommodate the fixing rib of a correspondence.

In certain embodiments, inner periphery and/or the outside of compensating part 300' can be the length at compensating part 300' In slightly change.The embodiment of Fig. 4 C shows that interior diameter d1 is slightly reduced a numerical value along whole length of compensating part 300' d1'.Overall diameter d2 then can be contracted to the end close to compensating part 300' similarly.Thereby, except in holding parts 340' and benefit Repaying beyond outside diameter d 2' after part 300' end may be reduced, the outside diameter d 2 of the whole length of compensating part 300' can substantially phase With.Thereby, the internal diameter of compensating part 300' and/or external diameter can whole length axially along gradually form taper, reduction or Change.This change may be produced via design or the error manufactured.Described taper is conducive to putting compensating part 300' Enter compensating part acceptance division 320.In some cases, can be arranged on this key area relative for the tapered distal end of compensating part 300' In the current downstream portion by the general direction of this device.It should be noted, however, that this taper is likely to produce at compensating part Each axial end portion of 300.

Fig. 4 E shows compensating part 300 " ' towards axial two ends formed taper embodiment.But, Fig. 4 E shows solid further The width holding rib 340 " towards compensating part 300 " ' end is increase, except rib 340 " of fixing completely measured with the degree of depth Diameter is likely larger than outside d3, and the diameter d2 of these fixing ribs 340 " can be considered compensating part 300 " ' expanded is less than diameter d3's Taper.Fig. 4 E also show annular fixing rib 340 " ' need not be continuous print, but a series of point-like or convex can be used Block is configured to annular pattern, to form the fixing rib 340 of separation configuration " ', it can substitute axially extended fixing rib 340 " or be additionally present.
