Description

Manually operated trigger type dispenser and assemble method thereof and used propeller spinner

The present invention is a kind of opening part that places container, is used to the clawback trigger action, makes the manually operated trigger type dispenser of liquid by the pump chamber pressurization back ejection of container inhalant liquid cylinder pressure, the propeller spinner of using on its assemble method and the dispenser that makes the pressure fluid eddy currentization.

This manually operated trigger type dispenser has the dispenser body that can load and unload at the opening part of container.Its body is to make with the synthetic resin of polyethylene.The dispenser upper part of body is equipped with action lever, the mechanism that can move when stirring trigger.The bottom protrusion is useful on and the vessel port place bonded assembly doleiform lid or the cylinder-like structure that can directly link to each other with opening part.Usually the lower part and the first half are perpendicular.And inside has the hydraulic actuating cylinder of pressure chamber to be arranged on the dispenser body interior.In the dispenser body, be provided with the feed liquor path that is connected with pump chamber.The axis on feed liquor path and dispenser body top is perpendicular.On the dispenser body, is furnished with the fluid path that is connected with pump chamber equally.

Usually the feed liquor path is positioned at vertical direction at the lower part of dispenser body.And the fluid path is positioned at horizontal direction at the first half of body.The axis of feed liquor and fluid path is orthogonal, and the first half of hydraulic actuating cylinder and dispenser body is one, and fluid path and hydraulic actuating cylinder then are positioned on the same axis, and the trigger that fiddles with will cause the crank motion of piston horizontal direction in hydraulic actuating cylinder.

The first half of hydraulic actuating cylinder and dispenser body be made of one and with the perpendicular downward extension of first half axis.The fluid path of the first half is made of the tubular portion of horizontal direction, piston vertically reciprocating trigger-type dispenser in hydraulic actuating cylinder known (for example US Patent the 3rd, 840, No. 157, the 4th, 227, No. 650).In such dispenser, the feed liquor path is not at the lower part of dispenser body and on piston.And and the first half be configured as the axis of hydraulic actuating cylinder of one and the intersect vertical axis of fluid path.

Another kind of piston vertically is installed among the dispenser body, and hydraulic actuating cylinder is along the vertical reciprocating trigger-type dispenser of piston also known (for example No. the 4th, 371097, US Patent).In such dispenser, the fluid path places the first half of dispenser body, and the feed liquor path is not located at lower part and on hydraulic actuating cylinder, and have with the perpendicular pipe of the axis of fluid path by the upper limb of the first half vertically downward.

And the major part of dispensers such as hydraulic actuating cylinder, piston, trigger, doleiform lid and dispenser body are equally all with the synthetic resin injection molded.

The dispenser of above-mentioned prior art is in the shaping of its body be processed with following problems.

Only there is the dispenser body of a tube to adopt movably mould and fixed mould cooperation shaping easily.But the dispenser body of above-mentioned present structure has two orthogonal tubular portions, i.e. the first half and lower part, the first half and hydraulic actuating cylinder and be made of tubular portion and first half assembly that the first half hangs down.Like this when machine-shaping with center pin by in the plane vertical with the moveable die moving direction vertically (as along the y of 19 figure to up or down) move and just necessitate.Be the die cavity 202 of this body and function of dispenser, only fixed mould 204 vertically on configuration in upright arrangement, just stay many wasted space thus between fixed mould, thereby limited the number of each dispenser body that can shaping.

And in the parts of dispenser, the dispenser body is than piston, the more complicated parts of trigger.The plastics of fusion under high pressure inject in the die cavity 202 of this body and function.But because die cavity 202 complex structures, the plastics of fusion can not promptly be full of die cavity, thereby have spun out the time of injection moulding.Moreover, owing to moving of core pattern also takes time, thereby further extended injection cycle.Like this, not only in each injection cycle can moulding number few but also cycle injection moulding is long again, the stock production of dispenser body is just very difficult.And because the complex structure of die cavity 202 makes that the mould structure of producing the dispenser body is also very complicated, cost of manufacture is also just very high.

For cheap trigger-type dispenser is provided, the dispenser body that not only structure is the most complicated is wanted the energy stock production, the production of miscellaneous part and assembling thereof also should be easy to carry out, but in the present trigger-type dispenser, be assembled in trigger, piston, pressure cylinder on the body, doleiform lids etc. are installed on the dispenser body and are fixed and all are not easy, so can not promptly assemble.

And as the essential structure of dispenser, pull back spring will be contained between piston and the pressure cylinder, and movable part (is generally piston, US Patent the 4th, 371, No. 097 dispenser is that pressure cylinder is movable, so movable part is a pressure cylinder) be subjected to outside pressure, so the tendency of deviating from is arranged.Therefore when built-up piston and pressure cylinder if pull back spring is placed therebetween, the two will be thrown off by pressurized.

Pull back spring, piston, pressure cylinder all separate in the existing dispenser, promptly in its design not with piston and pressure cylinder as one be assembled into the right member of the assembly  parent Chi kind virtue of  Yin 9 a glutinous rehmannia snail  residence of a high official R Ge play the Buddhist nunnery stand erect elaborate the hole on axe for installing a handle saddle cloth mire cup high slough off vinegar tomb ば horsefly rank,   children raised paths between fields scold earthworm tomb ば egg of a louse box dried flank meat instruct also the kind footpath between fields bed that returns of the waste cottonrose hibiscus  of what  of こ e type small jar punishment loess hills ┌ Yin examine  big shield  and have a nightmare and pay  

Moreover, nozzle casing is loaded on the top of the jet pipe of dispenser, and propeller spinner is installed between the nozzle casing and jet pipe on jet pipe top.

Propeller spinner is made by synthetic resin in the present dispenser, and its recess is in the central authorities of bottom apex, and the tangential direction of recess stretch out a pair of radial type trench arranged the bottom tube-like thing arranged.The through hole of its axis direction passes the bottom of propeller spinner, and radial type trench then is connected with the liquid road of jet pipe.The aperture that passes nozzle casing bottom centre simultaneously is corresponding with the recess of propeller spinner.

Because through the axial through hole of propeller spinner, radial groove flows into the recess of central authorities to the liquid of this structure pressurized when stirring trigger by the path in the jet pipe.Here, because radial type trench stretches out along the tangential direction of central indentation, pressure fluid is subjected to eddy currentization when flowing into recess by radial type trench, and the central authorities back that concentrates on recess is flowed out by corresponding aperture.Also there is the through hole of axis direction not pass propeller spinner, and between propeller spinner and jet pipe inside face, leave the gap, form annular channels around propeller spinner, pressure fluid flows to this annular channels by the path of jet pipe and flows into structure in the radial groove again.

Present from the above dispenser has axially extended recess and radially extends with propeller spinner at its top radial type trench.Formed so axial passage (recess) radially passage (radial type trench) and the structure of depositing, make the mould structure complexity of propeller spinner shaping usefulness, the manufacturing cost of mould uprises.And thereby the stock production of propeller spinner shaping difficulty propeller spinner cheapness is also just impossible.

And the liquid road of and jet pipe common with the outside aperture that links to each other, radial type trench and recess are connected.When not using dispenser such as the trigger misoperation, liquid can spill through aperture through the liquid road of jet pipe like this.Therefore, even if locked trigger when not using dispenser, also, the fluid path of jet pipe footpath aperture can not prevent that liquid remaining in its path from spilling because of linking to each other with atmosphere.

The present invention is suitable for quantity-produced dispenser body so that its structure to be provided, and is first purpose so that easy stack-mounted to be provided by the manually operated trigger type dispenser that parts organizing cooperating produces simultaneously.

The present invention is being its another purpose with the assemble method of pressing the manually operated trigger type dispenser that parts organizing cooperating produces.

The present invention is another purpose easy shaping to be provided and not to cause the dispenser propeller spinner of dispenser structure complicated.

And the present invention is also to provide the dispenser simple in structure that liquid can not revealed fully when not using to be its purpose.

The present invention is also providing the pattern of utilizing nozzle casing running transform flow of liquid in axial direction, and the liquid flowing mode transfer device that can set the inoperative position when not using is purpose.

In order to reach the 1st purpose, feed liquor path and liquid outflow pathway be not on the body of dispenser among the present invention.And piston and pressure cylinder be not also on body, and independent moulding respectively.The lower part that has the first half on the dispenser body and vertically stretch out with it.The piston body of the jet pipe of the hard-wired level of the body first half and the lower part device of body is perpendicular, thereby piston becomes shape.The lower part that pressure cylinder is placed in the dispenser body links to each other with the trigger that can stir, and interlock can be along the piston body crank motion mutually with the action of trigger.

Inlet is on the pressure cylinder and liquid outlet each self-forming on piston like this.The front of the lower part of this external dispenser body is provided with breach, and body just utilizes owing to the jagged elasticity that produces is connected as fastener means with the doleiform lid.This breach also makes the jet pipe of trigger rearward end and piston to pass.Moreover piston engages with pressure cylinder and can be pressure cylinder supporting role is provided when the inoperative position, bottom.

Manually operated trigger type dispenser 10 of the present invention shown in Figure 1 includes the dispenser body 12 of the synthetic resin injection molded of polyethylene kind.Body 12 comprises the first half 14 and the lower part 16 that is stretched out vertically downward by the first half, is installed on the opening part (19) of the container (18) that liquid is housed at lower part doleiform lid (20).Moreover, dispenser comprises hydraulic actuating cylinder 22, piston 24, and trigger 26, and hydraulic actuating cylinder, piston, trigger and dispenser body equally all are with the synthetic resin injection molded.

Fig. 2 can see that the first half 14 of dispenser body has from upper limb 14a, sagging pair of sidewalls 14b, and the back will be talked about, and piston 24 promptly is installed between two sidewalls.And stir trigger 26 as described later piston 24 is moved.In addition, the front portion of lower part 16 has breach 28, because the existence of breach, the lower edge of lower part has elasticity.Like this, utilize its elasticity that the body 12 of dispenser and the fixed form 32 that has the root 30 of the doleiform lid of bottomless drum shape to match are placed body lower part 16.(with reference to Fig. 3)

Fixed form 32 to shown in Figure 4, comprises the 1st fastening part 34 as Fig. 2, and below the 1st fastening part, the 2nd fastening part 36 that the bottom 30 of doleiform lid is fastening.Among the embodiment, the 1st fastening part 34 is embodied as the axial rib that is provided with at the back side of the lower part 16 of dispenser body.The 2nd fastening part 36 comprises the inclined-plane 38 that bottom 36 insertions of promising doleiform lid play the guiding role, the outward flange of the horizontal upper surface 39 of the protrusion parallel with the following cardinal principle of doleiform lid root.And leave big breach as the flange of the 2nd fastening part 36 and the extended line intersection of the 1st fastening part 34.Feasible the shaping easily of this breach is set carries out.34,36 the formation that no matter is the 1st or the 2nd fastening part all is not limited to graphic version, and can take other many different forms.

Have negative thread on the doleiform lid 20, its negative thread can be connected with the outside thread of container exit 19, can be with the dispenser body loading and unloading oral area that is installed on container freely by the doleiform lid.And in doleiform lid 20, seal cover cap 42 is housed as shown in Figure 1.The top of seal cover cap 42 has makes it can be placed in groove in the dispenser body lower part 16.Utilize doleiform lid 20 lower part 16 of body can be fixed in the opening part 19 of container, the lower part 16 of body is installed between the inside and outside wall 42a and 42b of seal cover cap upper end, and the upper end of seal cover cap is clipped between the upper end of the lower end of dispenser lower part and vessel port place 19 to guarantee sealing.And be useful on fastening recess at the inwall of the lower end of dispenser body lower part 16, and the inwall 42a of seal cover cap upper end has corresponding with it fastening projection 44.Owing to adopt this structure that the fastening effect of fastening recess 43 and fastening projection 44 is arranged, even covering 20, doleiform of no usely is screwed to vessel port place 19, seal cover cap can not thrown off yet.Fastening in an embodiment recess 43 is on dispenser body 12, and fastening projection 44 is on seal cover cap 42, otherwise with fastening recess on seal cover cap, fastening projection is also passable on the dispenser body, but when fastening projection was arranged on the inwall of doleiform lid 20, fastening projection that matches with it or recess were advisable with the outer wall that is located at the seal cover cap upper end.

The doleiform lid 20 of said structure, seal cover cap 42 is assembled into the lower part 16 of dispenser body with the following methods.

At first, if doleiform lid 20 is pressed to the lower part 16 of dispenser body, because the guiding on the inclined-plane 38 of the 2nd fastening part in the securing device, the lower end transformation of body lower part is shunk and the root 30 of doleiform lid is entered between the 1st and the 2nd fastening part be assembled on the body 12.After the root 30 of doleiform lid entered the first and the 2nd fastening part, the lower end of lower part 16 was because the recovery of elasticity original state.At this moment the upward movement of the base portion 30 of doleiform lid is subjected to the obstruction of the 1st fastening part 34, and because the root 30 of lower part lower end reinstatement doleiform lid will move downwards, the horizontal surface 39 of the 2nd fastening part stops its action.Special because the parallel outside protrusion of lower plane of horizontal surface 39 and doleiform lid root, thus prevent that reliably the doleiform lid from deviating from downwards, horizontal plane the effect of closing appliance.Doleiform lid 20 promptly is assembled on the dispenser body lower part 16 by this way.

Secondly, seal cover cap 42 is pressed into the lower part 16 of dispenser body in doleiform lid 20.The fastening projection 44 of seal cover cap upper end and the fastening recess 43 of body lower part link to each other like this.Since fastening recess 43, the fastening effect of fastening projection 44, and seal cover cap 42 is assembled into body 12 backs and just can come off.

With doleiform lid 20, even if seal cover cap 42 is assembled into the body dispenser and vessel port place 19 screw threads useless are tightened, doleiform lid, seal cover cap and body 12 also form a whole with said method.

But during actual assembled with described method with doleiform lid 20, when seal cover cap 42 is assembled on the body 12, as described later, simultaneously also with integrated piston 24, trigger 26, hydraulic actuating cylinder 22 is assembled on the dispenser.

By Fig. 1, Fig. 5 can be easy to see that hydraulic actuating cylinder 22 inside contain pump chamber 56, and its bottom minor diameter 58 is with it an one, and liquid route 60 is located at minor diameter.And valve seat 62 is in minor diameter 58 places of hydraulic actuating cylinder, and a valve 64 that forms with steel ball also is positioned at the minor diameter of hydraulic actuating cylinder.Suction tube 66 is installed on the minor diameter of hydraulic actuating cylinder and stretches in the container 18 in addition.This suction tube 66 preferably and hydraulic actuating cylinder 22 be configured as one.Label 67 valve guard for preventing that valve 64 from throwing off upward.

Can see that by Fig. 1,6,7 a pair of connecting plate 68 that stretches out from the back side of trigger 26 can fit with the step 70 of hydraulic actuating cylinder.Therefore as shown in Figure 1, stir trigger 26 and press the motion of arrow direction, hydraulic actuating cylinder 22 is to move vertically upward along piston 24 in the initial position with the trigger interlock by stop position, graphic bottom.And after removing the power that is added on the trigger, because the application force of pull back spring will be mentioned in the back, trigger, hydraulic actuating cylinder 22 are all got back to initial position.Guide part 71 with the minor diameter of hydraulic actuating cylinder minor diameter 58 easy fits is arranged on the seal cover cap 42, and hydraulic actuating cylinder 22 is because the guiding of this guide part crank motion normally.And a pair of outstanding holding pin 69 is arranged at the medial surface of trigger 26, utilize holding pin that trigger and piston 24 are connected as a single entity movingly.

Hydraulic actuating cylinder 22 has opening upwards as shown in Figure 1, is stretched in the hydraulic actuating cylinder by the body (piston body) 72 of opening part piston 24.And with hydraulic actuating cylinder inwall sliding block joint be integrally formed as the skirt shape seal strip 74 of the reciprocating guiding of hydraulic actuating cylinder with the lower end of piston 24.And pull back spring for example compresses wound spring 76 and is loaded in the hydraulic actuating cylinder 22 its upper end and joins with the stage portion 77 of piston body 72.

Anti-hook-shaped annular connecting plate 78 forms in the upper end of hydraulic actuating cylinder and outwards outstanding.Therefore, because this connecting plate is connected with cooresponding hook-type supporting slice on the piston 24, hydraulic actuating cylinder 22 is subjected to the supporting role of piston at its initial position as described later.

Shown in Fig. 1 and Fig. 8 to 11, piston 24 is included as the piston body 72 and horizontal-extending part 79 of the crank motion guiding of hydraulic actuating cylinder, is L-shaped substantially structure.Horizontal component 79 its front ends of piston are equipped with the effect that nozzle is built nozzle.And the back fluid path 80 that links to each other with aperture nozzle lid that will speak of is also on jet pipe 79.But the fluid path 82 that fluid path 80 is linked to each other with pump chamber 56 is on piston body 72.

Can understand that by Fig. 1 piston body 72 is splits with jet pipe 79 in an embodiment.And have connecting cylinder 84 with the jet pipe one in the rear end of jet pipe 79, in order to piston body is installed on the jet pipe.The upper end that valve seat 86 is positioned at piston body 72 is one with it, and the secondary valve 88 that is made of steel ball is placed in the upper end of piston body, utilizes it to cut-off connection between fluid path 80 and the connecting path 82.In addition that piston body 72 and jet pipe 79 is integrally formed, it is feasible too that secondary valve is located at jet pipe.With the coaxial stationary magazine creel 90 of connecting cylinder 84 be that upper limb by the rear portion of jet pipe 79 projects upwards.And stop sleeve 92 is to stretch out downwards with piston body 72 coaxial rear portions by jet pipe 79.The left part of stop sleeve 92 (front) has big breach (seeing the 9th figure), and 94 of hook-shaped connecting plates are positioned at the lower end of support sleeve window inwall (referring to Fig. 1, Figure 10).Connecting plate 94 is not all to have on the whole girth in stop sleeve 92 inwall lower ends, but sectional, has two sections in an embodiment.So the structure of connecting plate 94 segmentations makes and can core pattern be inserted by the hole 96 that the stop sleeve upper limb is worn, and carries out easily thereby make when being shaped.And, can be sleekly join with the connecting plate 78 of hydraulic actuating cylinder because 94 fens sections of connecting plate have just produced very big elasticity.

A pair of downward vertical plate 98 is positioned at the middle part of jet pipe 79, and hinge 99 is positioned at wherein, and the hook-type fastening part 97 that can be anchored on the root 30 of doleiform lid is positioned at the vertical plate lower end.And being positioned at the lower end of vertical plate 98 as the fixed orifice 100 of motion fulcrum, guiding is with 101 belows that are positioned at fixed orifice of recess.

When adopting structure assembling as above, the set pin 69 of trigger aligns fixed orifice 100, when pressing to jet pipe 79 by the below, set pin 69 is packed in the fixed orifice as guiding with recess 101, is about to trigger and is contained on the jet pipe.Therefore trigger 26 can be pulled the ground pivot suspension but be difficult for coming off from it on jet pipe 79.And come off the rear end of trigger and the jet pipe (see figure 7) that is connected from jet pipe 79 in order to prevent.Also can be different with embodiment, set pin 69 is satisfied with on the vertical plate 98 and cooresponding fixed orifice 100 to be arranged at equally also be feasible on the trigger 26.

Above-mentioned vertical plate 98 can hinge 99 as support motion.Therefore shown in Figure 11 long and short dash line, when piston 24 was shaped, vertical plate was positioned at level attitude, left and right sides vertical plate is fitted together after the shaping again.For the certain set of the fixed orifice 100 of the holding pin 69 that guarantees trigger and vertical plate, be necessary to make vertical plate 98 built-up times at a certain distance here.For this reason, by the fastening tube of the side protrusion portion 102 of a pair of vertical plate 98, be provided with the connecting plate 103 that can cooperate the opposing party simultaneously in an embodiment with fastening tube.With pack into fastening tube 102 o'clock of connecting plate 103, a pair of vertical plate is assembled at a certain distance, thereby trigger 26 is supported with piston 24 pivotings really with this structure.And for example in an embodiment as shown in figure 11, protrude the lower end that sheet 104 places right vertical plate 98.Like this, when the fixed orifice 100 of the set pin of trigger 69 and vertical plate fixed, the bottom of vertical plate can be to internal strain, prevented that set pin 69 from being deviate from by fixed orifice, to guarantee the pivoting supporting of trigger 26.

When as mentioned above the jet pipe 79 of piston being shaped, vertical plate can be formed in level attitude.Therefore, in the mould of jet pipe shaping usefulness, the shaping die cavity of vertical plate 98 can be positioned near the parting line, thereby just can be shaped with the mould of shallow simple shape.Make usually dark, the vertical plate that is shaped in the complex-shaped die cavity adopts the shape of hinge to be shaped in shallow simple die cavity.Like this, when the shaping dies cheapness of jet pipe can be made, because the easy shaping of jet pipe also facilitates Quantity production.

And the example that a pair of vertical plate 98 is combined with the distance of demarcating is not limited only to the structure of embodiment.

And for example a pair of fixed plate 105 shown in Fig. 8,9 is stretched out to the side by the upper limb of jet pipe 79.And has the attachment recess 4c(that can match in the side of dispenser body forebody) referring to Fig. 4, Figure 12 with the fixed plate 105 of jet pipe.And, can be the projection that is positioned at the bottom of dispenser body upper limb 14a with the cooresponding stationary magazine creel 106 of stationary magazine creel 90 bonded assemblys of jet pipe.(referring to Fig. 1) is owing to adopt this structure at positioning and fixing tube 90; By the bottom jet pipe 79 was pressed into body 12 at 106 o'clock; Stationary magazine creel 90 is pressed into stationary magazine creel 106,105 attachment recess 14c that are pressed into the dispenser body of fixed plate, thus be connected as a single entity.As shown in Figure 1, jet pipe 79 is packed among the dispenser body 12.Particularly such forebody and latter half of all supporting structures make being positioned on reliably on the dispenser body that jet pipe 79 can not become flexible.

Moreover, the top of jet pipe 79 is large diameter external thread part 108(Fig. 1, Figure 13) utilize this external thread part to link to each other with screw thread with the nozzle cover 110 that round-ended cylinder shape is arranged.And the propeller spinner 112 of the fluid under pressure eddy currentization that will be flow through by fluid path 80 is contained between the front end and nozzle cover 110 of jet pipe 79.Aperture 113 passes the central authorities of the bottom of nozzle cover 110.Utilization moves forward and backward the nozzle cover, regulates the distance between nozzle cover bottom and propeller spinner 112 front portions, and highly pressurised liquid can spray form or the outflow of jet flow shape.

And the propeller spinner of between jet pipe 79 and nozzle cover 110, placing 112, from the 13 figure bottomless drum shape that has for making as can be seen with synthetic resin.It can also be seen that the liquid road 114 of a pair of blind hole shape of 180 ° of mutual distances by Figure 13 and Figure 14, pass the axis direction at the propeller spinner back side 116.In an embodiment, the section on liquid road 14 is circular, but its section form, the number on liquid road and position are not limited to graphic situation.And for example the recess 118 of circle is relative with aperture 113 shown in Figure 15,16, passes the central authorities of propeller spinner 112 bottom front, and the outer rim of this recess is connected with liquid road 114.And the outer that the seal strip 120 of skirt shape forms in propeller spinner 112 can slip mutually with the inwall of nozzle cover 110, to guarantee the fluid tightness between propeller spinner and the nozzle cover.The circular depressions of reference marks 121 expression is the lightening hole that prevents the generation usefulness of shrink mark during for injection molded.

In the structure of above-mentioned propeller spinner 112, back side blind hole shape fluid path 114, expendable weight are with recess 121, and fwd recess 118 all extends at axis direction, and radial direction is provided with liquid road etc. and has formed succinct structure.Therefore propeller spinner molding die, simple in structure, Mold Making is cheap, so and because of propeller spinner 112 Quantity production at an easy rate that can be shaped rapidly.

Can see the multiple shape that nozzle cover 110 constitutes for the middle intermediate sleeve 124 that is installed with the central sleeve 122 of aperture 113 and is stretched out to the behind by the bottom in the central sleeve outside by Figure 13.The inwall of intermediate sleeve and the seal strip of propeller spinner 120 sliding block joints.

For preventing that the liquid lock phenomenon takes place breather need be set in the container 18.For this purpose as shown in Figure 1, the stage portion 132 to the minor diameter of the stage portion 130 of seal cover cap 42 and hydraulic actuating cylinder may process chamfering, the device that these stage portion can be done to ventilate in the closed contact places.Simple in structure can the assurance again of the breather of Gou Chenging seals like this.And because the action hydraulic actuating cylinder 22 of trigger 26 when rising by initial position, stage portion 130,132 deviates from mutually.At this moment the minor diameter 58 of hydraulic actuating cylinder is slided in the minor diameter guide part 71 of seal cover cap, therebetween, and gapped existence certainly.Therefore be connected when stage portion 130 inside and outside atmosphere of container 18 when 132 leave mutually, much less prevented the hydraulic pressure choking phenomenon certainly in the atmosphere inflow container of outside.

Being assembled in following a few procedure of trigger-type dispenser 10 that constitutes with above-mentioned structure member is easy to carry out.

(1) at first, the inner member of installing in dispenser body 12 is a piston 24, trigger 26, and hydraulic actuating cylinder 22 grades are given and are made its dress be one earlier.For this reason, as shown in figure 17, be benchmark with piston 24,22, valves 64 of hydraulic actuating cylinder, pull back spring 76, piston body 72, secondary valve 88 is arranged in order from top to bottom along the vertical axis 134 of piston.Then,, begin a valve 64 from hydraulic actuating cylinder as hydraulic actuating cylinder 22 is pressed into piston 24, pull back spring 76, piston body 72, secondary valve 88 is packed in the piston simultaneously.The concrete practice is secondary valve 88 to be satisfied with the upper end of piston body 72, the valve 64 of in hydraulic actuating cylinder, packing into, and pull back spring 76 under the situation of piston body is pressed into hydraulic actuating cylinder in the jet pipe 79 of piston and assembles.The connecting plate 94 of piston stop sleeve is radially outward strutted by the connecting plate 78 of hydraulic actuating cylinder when hydraulic actuating cylinder 22 is pressed into piston 24, and after connecting plate 78 passed through, because elasticity, connecting plate 94 restored, and connecting plate 78 and 94 is fixed up.Here, because of connecting plate 94 be sectional forming so have very big elasticity, in addition fastening even if connecting plate 78 and 94 also can slyness under very little pressure.Because connecting plate 78 and 94 is fastening, hydraulic actuating cylinder 22 is subjected to piston 24 supporting roles, can revolt the deflecting force of pull back spring and keeps its initial position.Connecting plate 78 and 94 is anti-hook-type and hook-type in an embodiment, but is not limited to this shape, as long as can make its structure of not leaving initial position all passable by support hydraulic cylinder 22.

Piston is fixedly the time, and the set pin 69 of trigger aligns the fixed orifice 100 of piston, trigger 26 is pressed in the piston 24 by the below again, utilizes set pin, after fixed orifice is fixing, trigger just by piston can pull pivot suspension.

Moreover, load onto propeller spinner 112 and nozzle cover 110 on the axis 136 of piston horizontal direction, at this moment, the nozzle cover is contained in external thread part 108 tightens, propeller spinner embeds the top of jet pipe 79, just nozzle cover and propeller spinner has been contained on the piston.

When with piston 24 as benchmark with hydraulic actuating cylinder etc. in the vertical direction assembling, and there is no need necessarily to carry out when trigger 26 and nozzle cover are installed in the horizontal direction with said sequence, the order appropriate change also is fine.

Will be for convenience of explanation at the hydraulic actuating cylinder on the piston 24 22, trigger 26, the parts that nozzle cover 110 grades are combined into one are called inner component assembly (assembly) 138.

(2) secondly, shown in 18 figure with dispenser body 12 as benchmark, with assembly 138, doleiform lid 20, the arrangement that the lower part 16 of seal cover cap 42 and dispenser body is coaxial.When the seal cover cap 42 below will being in upwards was pressed into, the anchor fitting 32 of dispenser body lower part embedded doleiforms lid 20 and fix as previously mentioned, and doleiform is covered and assembly 138 is contained on the dispenser body together then.And, seal cover cap also is contained on the body 12 because of the fastening projection 44 of the seal cover cap fastening recess 43 with the lower part lower end is fastened.This just can provide dispenser 10 as a finished product.If it is assembly 138 is placed the centre, that the combined method that body 12 is pressed on doleiform lid 20 and the seal cover cap 42 is feasible equally.

As mentioned above, hydraulic actuating cylinder 22 among the present invention, and piston 24 and body 12 are splits, and feed liquor path 60 and fluid path 80 place respectively on hydraulic actuating cylinder 22 and the piston 24.Promptly on body 12, do not have feed liquor path 60 and fluid path 80, the lower part 16 that vertically stretches out is only arranged.So body 12 designs simplifications, the die cavity simple shape of this body and function mould, the time of injection molded also obtains reduction.And and the fluid path 80 that the axis of lower part 16 intersects is not on body 12.Therefore need not aim at that fluid path 80 is provided with core rod and only can make body 12 injection moldeds with the mobile of moveable die.Owing to need not consider the moving direction of core rod, just the die cavity more than 3 can be placed in the fixed mould side by side like this, thereby can actv. utilize the space of mould.For example, as shown in figure 19, corresponding to y direction of principal axis in the present structure 2 this body and function of row's dispenser die cavitys 202 only can be set on fixed mould 204, the present invention such as long and short dash line are shown in the y direction of principal axis can be provided with 2 row's die cavitys 202 again, and each number of the shaping of body 12 has just had growth at double in each injection cycle like this.

Because the formation of the die cavity 202 of this body and function of dispenser is simple, thereby the time of injection molded has also just shortened.And owing to do not need the core rod of fluid path shaping usefulness, the shifting time of core rod has also just saved, thereby makes the cycle of injection molded further shorten.

Along with the dispenser body construction becomes simply, the number of each cycle injection molded increases by as mentioned above, and injection cycle has also shortened, thereby the Quantity production of dispenser body also just becomes possibility.Because the mould structure of dispenser body shaping usefulness is simple, manufacturing cost is also just cheap simultaneously.

Because vertical plate 98 is the forms that adopt hinge, be shaped so when piston 24 is shaped, can make on its direction in level.Like this, the die cavity of vertical plate 98 can be shaped near parting line in the mould of piston shaping usefulness, and adopt shallow, the die cavity of simple shape.The price of the mould that the piston moulding is used in the time of like this with piston 24 easy shapings and Quantity production is also cheap.

In an embodiment, be with fixing being assembled on the body 12 of piston 24, and hydraulic actuating cylinder 22 can with the structure of trigger 26 interlocks.But, hydraulic actuating cylinder 22 and piston 24 and body 12 splits are shaped in order to realize the Quantity production of body 12.Place on hydraulic actuating cylinder and the piston feed liquor path 60 and fluid path 80 just passable respectively.Therefore, if different with embodiment, hydraulic actuating cylinder is fixedly mounted on the dispenser body and makes piston and trigger interlock reciprocating, the feed liquor path places on the piston, and it is feasible equally that the fluid path places the structure on the hydraulic actuating cylinder.

But will be loaded on the piston 24 in the body, hydraulic actuating cylinder 22, trigger 26 with piston as benchmark strange in a difficult position pull out than aster hair on the neck than pinworm  haze storehouse lemon the quiet of fear have a liking for the inferior clump of assorted Φ  fragrant plant fall into oblivion pardon W string fear awake  mire Lv 38 after with doleiform lid 20, seal cover cap 42 is loaded on the dispenser 10 that has just obtained on the body 12 as finished product coaxially, as previously mentioned, to consider that from the Quantity production angle hydraulic actuating cylinder makes movable to shaping, or piston makes movable all passable.But considering from dispenser 10 stack-mounted angles, because movable member needs necessary supporting at its initial position, can hydraulic actuating cylinder be that movable structure just has been necessary as among the embodiment.

Parts only were pressed into and get final product when such arranged in co-axial alignment was installed, and were about to piston 24, hydraulic actuating cylinder 22, and trigger 26 incorporate assemblings are easy and rapid.When assembly 138 such as formation such as piston 24 inner components such as grade had been given elder generation's dress for one, as long as press body 12, the assembly doleiform covered 20, and the order arranged in co-axial alignment of seal cover cap 42 is pressed into, and then dispenser 10 has been finished with regard to assembling.Simplified the assembly working of dispenser 10 so significantly, made rapid, easy assembling become possibility.

Particularly owing to use the fastening of connecting plate 78,94, hydraulic actuating cylinder 22 is subjected to the support of piston 24, makes hydraulic actuating cylinder can not throw off from piston.Therefore, assembly 138 can be used as single-piece keeping and transportation.Doleiform lid 20, the shaping of seal cover cap 42 is had no problem because of its simple shape with processing.And as mentioned above, the shaping of dispenser body 12 does not have any difficulty yet.Moreover, body 12, doleiform lid 20, during the assembling of seal cover cap 42 and assembly 138, with its arranged in co-axial alignment, the dispenser body downwards simultaneously seal cover cap upwards press and get final product, technical do not have a difficulty.Simultaneously, body 12, doleiform lid 20, the shaping processing of seal cover cap 42 there is not difficulty yet, and since the assembling of they and assembly 138 also carry out easily, so even if their shaping processing and assembling also carry out easily in the under-developed area.In addition as mentioned above, be convenient to transportation after assembly 138 is integrated, the supply of material of assembly just there is not difficulty yet.Like this, give in the factory as maincenter and to make assembly 138 earlier, offer other factory and doleiform lid 20 then, seal cover cap 42 is assembled on the dispenser body 12 together, and all can adopt the mode that parts organizing cooperating produces of pressing.When pressing the mode of production production of parts organizing cooperating, employee's quality etc. just is not very serious problem, thereby can be to dispenser 10 Quantity production.Even if this dispenser 10 also can stock production so abroad or in the backland factory of domestic skilled labor's deficiency, can guarantee that in the locality workman originates.

Moreover, the design that only changes assembly 138 just can provide the dispenser 10 of various design and pattern; For example, in nozzle cover 110, take sponge shape breach and barrier is set obtains the expansion type dispenser as foam device.Therefore,, and supply with assembly 138 to other factory in the maincenter plant produced, just can be by to the management of assembly and then to comprehensive manufacturing program, design modifications etc. are managed, thus easier control.

After being contained in suction pipe 66 in the hydraulic actuating cylinder 22, packing engineering finally finishes again.The shaping of suction pipe and chimericly also do not have any technical difficulty.

The propeller spinner 112 of said structure and nozzle cover 110 constituted and can have been flowed out by aperture, and the flow pattern of pressure fluid carries out conversion, liquid flowing mode mapping device 140.

The trigger-type dispenser 10 that propeller spinner 112 is housed of said structure, placing nozzle cover 110, to make it be right-hand when mobile backward, the central sleeve 122 that is accompanied by the mobile nozzle cover bottom of nozzle cover enters the recess of propeller spinner, and its top and recess bottom surface 119 are adjacent to (seeing Figure 13).Central authorities sleeve 122 and recess bottom surface 119 are adjacent to and just make the fluid path 80 and compulsory partition of being communicated with of aperture 113 of blind hole shape fluid path 114 intervenient nozzles.Central sleeve like this is adjacent to the structure of cutting off forcing being communicated with of the fluid path 80 of nozzle and aperture 113 on recess bottom surface 119, because the effect of recess 118, from the fluid path 80 of nozzle and blind hole shape fluid path 114 to the highly effective prevention of the energy of flow of the highly pressurised liquid of aperture 113, the effect that is not intended to of trigger 26 when therefore confirmable restriction is not used, thus actv. prevents the leakage of liquid.Like this, also can actv. prevent the path 80 of nozzle, the leakage of remaining liquid in the blind hole shape fluid path 114.

And the central sleeve 122 of nozzle cover and the recess bottom surface 119 of propeller spinner are adjacent to, only mobile nozzle cover 110 gets final product.So the inoperative position, position when dispenser does not use can very simply and promptly be set.

Central authorities' sleeve 122 is positioned at the bottom of the nozzle cover that is installed with aperture 113, because this central authorities' sleeve can be adjacent to the bottom surface 119 of propeller spinner recess, the structure of nozzle cover 110 has just become simply, and makes dispenser 10 also become simply.Like this, structure of the present invention and the sort of propeller spinner 112 that utilizes are pinned trigger, and utilize stopper structure that the aperture leak free is present when not working obvious dispenser of the present invention 10 structures of comparing more simple.And because the parts that are not exposed on the external also obtain appearance attractive in appearance easily.

And for example nozzle cover 110 can utilize the spiral shell mosquito on it to move forward and backward among the embodiment shown in the figure, and this is much more superior than only sliding.In the time of will being satisfied with dispenser 10 container 18 of liquid is housed, when transportation and sale, should be placed on the inoperative position certainly.

When using dispenser 10, at first rotate nozzle cover 110 and be moved to the left (advancing) away from the inoperative position, promptly central as shown in figure 20 sleeve 122 is left by the recess bottom surface 119 of propeller spinner front portion and makes central sleeve, recess produces certain clearance between the bottom surface, and at this moment fluid path 80 and the aperture 113 owing to nozzle cover 110 mobile jet pipe left just has been communicated with.Like this, as shown in figure 15, blind hole shape fluid path 114 and recess 118 just also have been communicated with mutually with the outer rim of recess.At this moment pressure fluid flows into recess 118 by the fluid path 80 footpath blind hole shape fluid paths 114 of jet pipe, and pressure fluid eddy currentization in the space between central sleeve 122 and recess bottom surface becomes vaporific by aperture 113 ejections behind central boundling.

The a part of pressure fluid that flows into recesses 118 by blind hole shape fluid path 114 flows into the outside face of central sleeve 122, flows radially outward.But as seen from Figure 20, because the phenomenon that fluid under pressure is revealed by the gap of nozzle cover 110 and propeller spinner 112 can not take place in the inhibition of the seal strip 120 of piston.

Because recess 118, central sleeve 122 is generally concentric circle as shown in the figure again, as long as but being not limited to the shape that circle can help the pressure fluid eddy currentization on using all can adopt.

Make liquid flowing mode be transformed to the jet flow shape as long as nozzle cover 110 is further twisted forward by the spray flow shape, the distance that makes propeller spinner front portion and nozzle cover bottom 109 is greatly to a certain degree getting final product.(seeing Figure 21).There are enough distances the front portion that makes propeller spinner bottom to the bottom 109 of nozzle cover, between central sleeve 122 and the recess bottom surface 109 big gap is just arranged.Like this, flow through pressure fluid that blind hole shape fluid path 114 flows into recesses 118 just no longer by the eddy current change by the fluid path 80 of jet pipe, and become the jet flow shape by aperture 113 ejections.

Like this nozzle cover 110 is moved forward by the inoperative position, just can obtain from the spray flow state to the continuous setting of jet flow state, the flow pattern of liquid can be easy to rapidly be changed.And because aperture 113 passes the central authorities of the bottom 119 of nozzle cover, liquid flows out by certain position usually.

When the jet flow position, nozzle cover 110 moved right on the contrary (retreating) then can set to the off position order by the spray flow state.

Make after liquid flows out with desirable liquid flowing mode, nozzle cover 110 is moved backward, the central sleeve 122 and the bottom surface 119 of recess are adjacent to, at this moment produced very big resistance and made the mobile difficulty that becomes of nozzle cover.Like this, just retreat again at need, promptly arrived the inoperative position of setting, be easy to just can feel and arrived the inoperative position when nozzle cover 110 retreats into certain position.

The liquid flowing mode mapping device 140 of above-mentioned form also can make liquid flow out by spray flow or jet flow state rapidly easily when utilizing the mobile setting inoperative position of nozzle cover.

Wish to have the suitable mark that can see the liquid flowing mode that to discern corresponding to the miles of relative movement of nozzle cover 110 like this.Serve as a mark, for example can on dispenser body 12, stamp " △ " formula mark, on nozzle cover 110, engrave Spray, marks such as Jet.With " △ " and Spray, the nozzle cover is positioned at the spray flow pattern during alignment in this structure, represents then when △ aligns with Jet that the nozzle cover is positioned at spray pattern, can correctly select various liquid flowing modes rapidly thus.

The inoperative position obtains owing to nozzle cover 110 is fully moved to right, so set easily.But as mistake is moved back nozzle cover 110 to such an extent that too much just might cause damage to the recess 118 of central sleeve 122 and nozzle cover.Therefore stamping the mark of Off on the nozzle cover, when △ aligns with Off, promptly is to be positioned at the inoperative position.

For preventing that nozzle cover 110 from moving too much hope stop motion mechanism can be set, the 22nd, 23 two figure is an embodiment of nozzle cover stop.As shown in figure 22.The thin plectane 144 that has course setter 143 above being equipped with on the jet pipe 79 of the behind piston of external thread part 108.Suppose that outside thread 108 is right-hand screw mosquitos, course setter upper surface 143a is relative, and plectane 144 is the inclined-plane, and lower surface 143b is then vertical with plectane 144.Like this, there is the inside flange 146 with course setter 143 mating reactions at nozzle cover 110 rear portions as shown in figure 23, and the breach of embedding is arranged on the flange.Here the top 146a of breach face is that the following 146b in inclined-plane then is vertical surface.

The jet pipe 79 of structure places nozzle cover 110 as mentioned above, utilizes the outer spiral shell mosquito 108 of jet pipe to be connected with the nozzle cover.As shown in Figure 1, when the right-hand revolution, it moves right with nozzle cover 110, and the inclined-plane 143a of course setter is connected with the inclined-plane 146a of flange, and flange is limiting course setter 143.The plectane 144 usefulness light sheets that at this moment course setter is housed are made, and high resilience has the function of plate shape spring.Therefore when being connected with the inclined-plane 143a of course setter, the inclined-plane of flange 146a compresses mutually, because elastic circular plate 144 deforms, for will from the breach of 146a, deviating from, the inclined-plane 146a of flange need cross the inclined-plane 143a and the vertical surface 143b of course setter, but this only right-hand revolution nozzle cover 110 realize.To anticlockwise direction rotation nozzle cover 110, vertical surface 143b and 146b joined thereafter.When vertical surface 143b and 146b joined, plectane 144 did not deform, and can prevent from reliably to rotate to anti-clockwise like this.

The plectane 144 that the utilization of this form is provided with on jet pipe comes the structure of usefulness as plate shape spring, and it is all uncomplicated with processing to be shaped, and not only simple structure can obtain failure-free anti-rotation effect again.

In an embodiment, liquid flowing mode switching mechanism 140 is housed on trigger-type dispenser 10.But in the dispenser of other form except the trigger-type dispenser also tip garden deep blue stop the widely different J of the loyal standing grain of Buddhist nunnery rank and change  40.The lifting that for example is contained in the piston that utilizes lifting button switch interlock freely is to the plug-type dispenser of liquid pressurization and utilize container self to compress on the compression dispenser to the liquid pressurization.It also can be contained in the dispenser that utilizes flowing gas (Off ロ Application ガ ス) and by on the electrodynamic type dispenser of drive motor to the liquid pressurization.In the aperture front barrier being set in addition, is feasible thereby make the spray flow that is sprayed by aperture collide foamingization mutually with barrier.Nozzle cover 149 structures of expansion type as shown in figure 24.This nozzle cover 149 has the sleeve 150 that is forwards stretched out by bottom 109, and stretching out has bevelled barrier 152 on the sleeve.Barrier 152 does not collide mutually with the core flow part of the pressure fluid that is sprayed by aperture, and only peripheral with it liquid phase collides.

And outstanding air intlet 154 being arranged at axis direction, this admission port is positioned at the outside radially of central sleeve 122, passes the bottom 109 of nozzle cover.Can see that basic 4 air intlet 154 equal angles for rectangular cross section distribute by Figure 25 in an embodiment.But the shape of admission port section, number and arrangement are not limited to graphic situation, but an admission port will be arranged at least.

The dispenser 10 of this nozzle cover 149 is housed, by the peripheral liquid of the pressure fluid of aperture 113 ejection and the barrier 152 collisions miniaturization that becomes, and the core liquid phase mixed foamingization of the pressure fluid that will not collide by air intlet 154 leaked-in airs with barrier 152.

Have barrier 152 as above-mentioned utilization, the nozzle cover 149 replacement nozzle covers 110 of air intlet 154 are contained in and have just obtained the expansion type dispenser on the dispenser 10.

Has seal strip 120 with propeller spinner in the structure of the nozzle cover of the multiple tubular of the intermediate sleeve 124 of inside face sliding block joint this, radially outer edge at intermediate sleeve, the bottom 109 of nozzle cover is provided with air intlet 154, thereby does not destroy the fluid tightness between propeller spinner and the nozzle cover.And nozzle cover 149 apparatus there is a dispenser that is easy to just obtain foaming type after nozzle cover 149 replacement of air intlet 154.Because interchangeability is fine, most parts are shared, thus the equal stock production at an easy rate of the dispenser of common dispenser and expansion type.

And the air intlet 154 of nozzle cover 149, barrier 152 stretch out by axis direction, thereby the nozzle cover is shaped easily, and nozzle cover itself is stock production at an easy rate also.

The above embodiments are to explanation of the present invention, rather than limitation of the invention, present invention includes distortion of the present invention in the technical scope of invention, and transform.

As mentioned above, dispenser of the present invention be feed liquor path and fluid path all not on the dispenser body, thereby the dispenser body just need not form the axis that intersects vertically. Like this, the structure of dispenser body has just been oversimplified, and just can not want stem stem during injection molded. The number that is shaped in each injection cycle like this increases, the injection cycle shortening of having got back, thus so that the large-scale production of dispenser body becomes possibility. And because the dispenser body can be mass-produced, the producing cost of dispenser itself is also just cheap.

Since the piston that installs in the dispenser body, hydraulic cylinder, and the inner parts such as trigger are assembled into one easily, are taken care of and transport so can be used as an assembly integral. Because inner part provides to give the inner part assembly that installs earlier, use like this inner part assembly again, the dispenser body, doleiform lid, seal cover is just assembled again to have carried out easily, so also just simplified as the production of the dispenser of finished product.

As mentioned above, among the present invention, piston, hydraulic cylinder, the inner parts such as trigger are all with the unseparated whole supply of material. Like this, will be with the factory that produces and supply with piston assembly as maincenter, can with the dispenser body of preparing in the locality, the nozzle cover, seal cover is assembled into dispenser. Like this because present structure is difficult to realize production by the dispenser of component organization coordinated production, because the present invention becomes possibility.

And owing to adopt this mode of pressing the component organization coordinated production, will in addition after the conversion, can provide the dispenser of various different designs patterns at the assembly that provides to other factories after the maincenter plant produced. And by assembly is managed, can be from a comprehensive angle to the production schedule, design alteration is controlled easily.

And as mentioned above, propeller spinner of the present invention is the succinct structure that does not have along the liquid road of radial direction, and the mould of its shaping usefulness is simple in structure, and the Mold Making expense is also just cheap. And because propeller spinner can be shaped rapidly cheapness production that can be a large amount of.

This propeller spinner and the nozzle cover assembling with the central sleeve that can be adjacent to the bottom surface of propeller spinner recess have just obtained the dispenser of easy setting inoperative position. Like this, when placing the inoperative position, this dispenser can cut off reliably being communicated with between the fluid path of aperture and ambient atmosphere and jet pipe. Therefore, not only can prevent because the leakage of the liquid that the no intention action of trigger causes, and can prevent reliably the leakage of liquid remaining in the fluid path of jet pipe.

This dispenser, the nozzle cover only moves by axis direction, and is textural also just simple. And because the parts that do not have the outside to expose obtain beautiful profile easily.

And, the nozzle cover is assembled on the propeller spinner, simply constructed liquid flowing mode switching mechanism is easy to just consist of. The liquid flowing mode switching mechanism that so consists of is fully moved the nozzle cover backward and is just reached the inoperative position. This mobile structure of setting the inoperative position of utilizing the nozzle cover is easy to set the inoperative position, and structure has just been simplified.

With the nozzle cover forward turn leave the inoperative position along with obtaining spray flow or jet flow jet flow to the front distance difference, but the conversion at high speed of liquid flowing mode be easy to carry out.

At this moment the aperture position of the ejection of spray flow or jet flow need not change and just can obtain the ejection of spray flow or jet flow.

In addition, the structure of the center hub tube inner surface of nozzle cover and the seal strip sliding block joint of propeller spinner, air intlet can not destroy the fluid tightness between propeller spinner and the nozzle cover in the bottom of nozzle cover.The nozzle cover that therefore will have barrier and an air intlet has been easy to just obtain the dispenser that foams shape during with the propeller spinner combination.

Therefore utilize this propeller spinner can obtain the good dispenser of interchangeability.Be the dispenser of common dispenser and expansion type because to adopt most parts are public structures, can produce cheap and on a large scale.
