Fig. 1 is the block chart showing the Sprinkler 10 according to the present invention one exemplary embodiment.This watering modular
Device 10 can include main body 20, operating parts 30 and a shower nozzle 40.This main body 20 is available for an operator along one portion
Divide and grip.In some cases, the part that can grip can define a grip portion 22 of main body 20, and this grip portion 22 can be by
It is arranged 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 group
Part 50 is configured so that (for example, Sprinkler 10 performs a control function relevant to the current by Sprinkler 10
The current of exit portion 24 it are flow to) from intake section 26.
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 or stop to flow through the current of Sprinkler 10.Therefore, in some cases, operating parts 30 can be in current control
As being turned on and off (partially or fully) valve body or the operating assembly of other flow cavitation result assemblies in assembly 50 processed.Operating parts
30 especially can interface with the on-off control assembly 52 in flow cavitation result assembly 50.In some cases, flow cavitation result assembly 50
Can have a flow control function further, so that it more can be according to the control of operator beyond open and close current
Water flow is done a certain degree of regulation by system.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, permissible
Through a flow control member 60, flow control assembly is operated, this flow control member 60 can be the body of rod, button,
Adjustment disk 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

Bad.For example, when water is frozen, its can the region of these uniquenesses of this runner and arround the assembly of cincture defined
Have in the space of fixed volume and produce volumetric expansion (that is, internal functional assembly).Pressure therefore can be at fixed volume
Space increases, and when pressure increases to enough values, the flow path wall of water the most likely can rupture, and more likely cause
The damage of internal functional assembly.
As it has been described above, therefore these regions being likely affected can be considered " key area ", and this key area
The entrance area between inlet portion 26 and on-off control assembly 52 can be included, be positioned at on-off control assembly 52 and flow control

Slightly flow control assembly 54), some embodiment may only have two key areas.But, in this manual, it should be appreciated that
" key area " word should be considered container, space or be formed adjacent near the internal functionality assembly of Sprinkler 10
Other regions of runner.Additionally, in this manual, internal functionality assembly can include flow cavitation result assembly 50 and spray
The assembly of 40 (such as, nozzle segments of shower nozzle 40).
Described compensating part can be configured to avoid because of water in key area because freezing or the pulse that is under pressure is made
The expansion that becomes and the infringement that causes.For in this regard, such as, compensating part can be inserted in this 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.For example, compensating part can be by
Deflection and/or have resilient material and make, thus can absorb repeatedly under conditions of not causing permanent deformation
Compressing and expanding.Therefore, compensating part can be by made by compressible material, and this compressible material is configured so that compensating part
Can be compressed in key area, thereby freezing or the pulsation of water and effective appearance of increasing in key area in response to water
Long-pending, to avoid the internal functionality assembly of Sprinkler 10 to be damaged.In some cases, compensating part can be by compressible
Material is formed as the cylindrical tube of hollow, and described compensating part can be placed in key area and become compressible component, mat
This makes the dischargeable capacity of key area at least increase by 10%.Therefore, compensating part can contain or compensate the water by freezing and made
The volume of the increase become.In some cases, compensating part can have enough compressibilities, so that key area is effective
Volume increases by more than 25%.
In some cases, compensating part can be made up of the elastomer such as thermoplastic elastomer (TPE).Compensating part can have
Multiple confining gas spaces (such as, glass bubble), described confining gas space is formed and is distributed in the body of whole compensating part
In Ji.Therefore, described compensating part can by made by a kind of material being similar to rubber, foaming, and wherein have multiple in
Empty enclosed slot room.Confining gas space (that is, hollow enclosed slot room) can be fluid-tight structure.These confining gas spaces can
Think compressible structure so that compensating part is compressible structure, thereby accommodate water caused when being formed as ice swollen
Swollen.Therefore the increase (that is, volumetric expansion) of water volume can be compensated by the volume compression of corresponding compensating part.Then, ice is worked as
When block dissolves, confining gas space is expanded, so that compensating part can enter when water converts back liquid and takies less volume
Row volumetric expansion.It should be noted, although multiple confining gas spaces can be distributed in the material of similar foaming, and some is implemented
Example can also use has minority or the only compressible gas compartment a such as rubber or other bendable material work
For compensating part.

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 with multiple shower nozzles
In selected one be connected.Shower nozzle 120 is a kind of specific example of the shower nozzle 40 shown in Fig. 1, and be multiple can be with
One of them of the shower nozzle that export department 112 engages.
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.But
It is that in certain embodiments, export department 112 can be arranged along export department's axis 113, so that export department 112 is relative to axis
There is between 118 an angle.Furthermore, it is possible to select different agent structures different to define between axis 118 from axis 113
Angle.
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.It should be noted that still, pivoting point can also be alternatively arranged at the other end of trigger member (so that pivoting point position
In the intersection near axis 118 with axis 113).One end relative with pivoting point in trigger member 140 can by alternately towards
Main body 110 is compressed, and can thereby adjust on-off control assembly 52 to be separately turned in the past away from the direction extension of main body 110

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 being pressed 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
Nozzle is located exactly at when allowing all or most current are dry angle, and the aquiform stool in the first exit region 210 can be to
Flow outward.But, when Sprinkler 100 is just unfavorable for therein from hose reel or the angle hung from other devices
Water flows out, be positioned in the position held water within the first exit region 210 when flow control valve, and/or when nozzle is close
In time closing, aquiform stool can rest in the first exit region 210.Additionally, when nozzle is opened slightly, cold air be easy to by
First 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, when on-off control assembly 52 is assumed to be the state of closedown, and when flow control assembly 54 is almost in closing
State, and/or when the angle of Sprinkler 100 is unfavorable for that water therein flows out, the second exit region 220 is in the situation freezed
During generation, the ability of its pressure release is next to the lowest region, and therefore, the second exit region 220 can be considered the second key
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
To merge with the first exit region 210.
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 institute
State key area can be formed respectively to receive at least one compensating part.Owing in some cases, a key area can set

The view obtained.Fig. 4 C shows the alternative view into the alternate design in the assembly shown in display Fig. 4 A.Wherein, Fig. 4 C shows
Fixing rib on compensating part 300 ' and key area.
As shown in Figure 4 A, compensating part 300 can have generally hollow cylinder, and key area can be in runner
Generally hollow column part.Therefore, in most basic embodiment, compensating part acceptance division 320 may simply be runner
In there is the part (such as a, part for the tube body of runner) of length that is enough accommodating or that receive compensating part 300.As
This, compensating part acceptance division 320 may simply be a part substantially identical with the length of a compensating part in runner.Compensating part connects
Receipts portion 320 need not be defined by any other special feature.It should be noted that compensating part 300 is the most in all situations
All it is necessary for hollow cylindrical.For example, in certain embodiments, compensating part can have any current that can allow at stream
The shape of flowing in road, and have and can be maintained at compensating part in runner to bear the shape of volume contraction when necessary.
Therefore, 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 that shape matches, replaces a part for the whole compensating part 300 of display in Fig. 4 A), or any other suitable shape
Shape.
In certain embodiments, compensating part 300 can have an an interior diameter d1 and overall diameter d2.On the other hand, close
The inner rim of key range 310 can have a diameter d3.In some cases, diameter d3 can be slightly less than diameter d2.Such one
Coming, compensating part 300 need to be by slight compression when being housed into compensating part acceptance division 320, and by the inner rim of key area 310
Put on the strength on compensating part 300 should enough to be fixed by compensating part 300 when current are by runner, or enough can mend
Repay part 300 to be inserted in the assembling process of Sprinkler (such as, Sprinkler 10 or 100) and fixed by compensating part 300.
As shown in Figure 4, when being not provided with compensating part, runner can be defined by the inner rim 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 caused 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.
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 promote to be protected by compensating part 300 for fixing arranging for runner
Hold the feature in location.About this point, in some cases, compensating part acceptance division 320 can be configured to have fixing rib
330, described fixing rib (that is, can be parallel to the longitudinal length of runner along the inner rim of key area 310 ' at an axial direction
Direction) upper extend.But, alternatively, fixing rib can also have the ring-type shape (dotted line such as rib 330 '
Shown in), it can extend around the inner rim of runner, and is positioned in the plane being approximately perpendicular to axial direction.Additionally, at certain
In a little situations, annular ring can be arranged at each longitudinal end of compensating part 300, thereby defines compensating part acceptance division 320
Length, and limit compensating part 300 movement 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 C show longitudinal extension fixing rib 340 an example, wherein, Gu
Hold rib 340 to arrange along the neighboring of compensating part 300 '.It should be noted that can include in certain embodiments one with
The multiple example of the fixing rib shown in figure 4 above C.Therefore, it can by shown fixing rib with required number of times replicate (or
With any required combination), to be provided with multiple fixing rib (identical or different kind) in some cases.
In one exemplary embodiment, Sprinkler 100 can be provided with one or multiple benefits in key area
Repay part 300 to protect Sprinkler 100.By these for the safeguard procedures freezed or set by infringement that pulse causes, spill
Water device 100 can become the most strong and durable.But, another aspect of the exemplary embodiment of the present invention more can have
Sprinkler 100 is made to have the ability of modular characteristic.Consequently, it is possible to during assembling, can substantial amounts of manufacture one
The parts of whole group, and can selectively described unit construction be configured to define different types of device.In some cases,
Single kind and the compensating part of size can be produced in large quantities and by it in Sprinkler 100 is inserted in selected position, mat
This defines different grades of safeguard procedures.Thus, it may not be necessary to make for different grades of product in the fabrication process
With different instruments, it is also possible to arrange different grades of protective measure for different grades of product.In certain embodiments, mould
The Sprinkler assembly external member of massing can have all selectable parts, selects suitable group according to demand for user
Close.
Accordingly, in some cases, the quantity and/or the kind that are arranged on the compensating part in Sprinkler 100 can define
