Description

Fluid bullet transmitter

Technical field

Total (but the not exclusive ground) of the utility model relates to toy projectile transmitter, relates in particular to a kind of mechanism that intact substantially liquid " bullet " can be penetrated air.

Background technology

Long ago, people have attempted creating the device that is used for launching solid-state projectile.These devices begin to be used to go hunting, to attack and to defend most.They may become human spirit's a part now.Like this, the projectile transmitter is a kind of popular toy for children forever.

In the distortion of a kind of prior art of this toy, a kind of transmitter of rifle shape is supported with one or more projectiles, and these one or more projectiles can be launched by the emitter that spring-loaded trigger mechanism or air pressure drive.Projectile has had the shape of equivalent variations, and has comprised the arrow or the emitter of table tennis, foamed elastic ball, lightweight emitter and foams.In the U.S. Patent No. 4,892 of investing Moormann, disclosed the example of these solid projectile transmitters of the prior art in 081 (1990) and invest its U.S. Patent No. 4,694 equally, 815 (1987).

The water transmitter that also has many prior aries.The competition of toy industry is quite fierce, in order to make a profit in the groove from the intrinsic of toy, has has in these years researched and developed hundreds of thousands of kinds of different water transmitters.Yet in the prior art, the water of emission never shows as a kind of solid, compact projectile.The substitute is, the shape of the water of launching falls into one of three kinds of basic classifications.The first kind is the solid stream of water of periodic interruptions, as being produced by basic ejecting gun.Second class is launched is water elongated, that disconnect or irregular amount, is similar to the formed pattern of water of jettisoninging out by from cup or bucket.At last, be the device of the numerous water drops of emission.Up to now, also there is not to launch the toy apparatus that is similar to the such water bullet of not following drop substantially of the stone that flies over air.

In people's such as D ＇ Andrade U.S. Patent No. 5,074,437 (1991), disclosed the example of a kind of " continuous flow " transmitter.In this device, set up and store air pressure by swabbing action, then be used for water supercharging selectively to storing.When actuated triggers, the current that the motion of pressurized water by narrow nozzle is pushed into generation.When trigger engaged, these current were continuous, and threw off or when the driving pressure of water equaled atmospheric pressure, current stopped when trigger.In the U.S. Patent No. 5,433 of Tarng, the example of second kind of " continuous flow " transmitter has been described in 646 (1995).This device need not make the water circulation just can interrupt current with quite high frequency.

In the U.S. Patent No. 5,339 of D ＇ Andrade, mentioned the example of the transmitter of a kind of " the irregular water yield " in 987 (1994).This invention provides a kind of trigger mechanism, is used to control flowing of water that explosion discharges.The shape of this explosion is elongated and irregular, and is made up of numerous little water bundles.

People's such as Liu U.S. Patent No. 5,662,244 has proposed the example of a kind of " multiple drop " transmitter.This utility model is set forth: " the present invention has the general advantage of traditional hydraulic giant, but the water lastics (water charge) that the present invention penetrates can be the explosion of water or the shape of spray, and these water can drop on the predetermined target more, and need not accurately aim at.

Although above-mentioned one type of prior art syringe provides the means of some amusements and pastime for the user, they still have some shortcomings, thereby are also needing transmitter more interesting and that improve to some extent in the art.Some shortcomings of solid projectile transmitter are:

(a) the solid projectile is lost easily, causes the play value forfeiture of transmitter thus or is restricted.

(b) the solid projectile must be retrieved, and recreation is interrupted.

(c) the solid projectile may cause pain or injured owing to impact.

(d) the solid projectile can make toy increase extra manufacturing cost.

On the other hand, transmitter of the prior art can not make water launch as a kind of interrupted, compact, vision identifiable " bullet ".In recreation, this will show as following shortcoming:

(a) children are difficult to play the part of the people of solid body emission such as stone or the bullet.

(b) water of launching can not provide by being felt that object hits, and does not have gratifying " bang one " when hitting.

(c) owing to do not fetch discrete emitting substance, therefore, the water of water transmitter emission of the prior art is unsuitable for traditional shooting game.

The utility model content

Therefore, the utility model can be used to overcome shortcoming of the prior art, and the outward appearance of the liquid projectile of flight aloft of the utility model emission and performance thereof are as a solid flying object.

Theoretical foundation of the present utility model is for single liquid bullet can be kept perfectly when flying over vacuum, and each molecule of described fluid must be along same direction and with the operation of same speed (promptly not turbulization).In order to realize this state, preferred embodiment of the present utility model is attempted at first predetermined amount of liquid being packed in the mobilizable container, described container is quickened, so that each molecule of liquid turbulization and moving along same direction not with same speed.At last, the utility model provides a kind of device that discharges bullet from container, and this can not cause turbulent flow yet equally.This result is configured to when liquid flows along sidewall and leaves container turbulent flow to be minimized and will realizes in the release of the vacuum between back chamber wall and the fluid by the moment of slowing down at described rear portion chamber wall by the sidewall with container.The result of this release has produced a kind of flight, complete substantially liquid bullet aloft, and wherein all molecules all are to move along same direction and with identical speed.

Purpose and advantage

Therefore, the purpose of this utility model and advantage are:

(a) can be with water as projectile, and this normally can supply in a large number.So just, can eliminate the hidden danger of losing the projectile of being produced, and eliminate the obsolete situation of toy thus.

(b) can be owing to need are fetched the process that projectile interrupts playing.

(c) can sell transmitter in company with selling the production projectile, this has just reduced consumer's cost.

(d) although projectile can be made of water, children can play the part of the people of emission stone, bullet and so on solid.

(e) emission bullet that is made of liquid is difficult for causing pain or injury when bump.

(f) different with water emission toy of the prior art, the utility model can be launched and the similar projectile of solid body.The sensation of hit can be provided, and when hitting, can send " bang " sound.

(g) the utility model can be used to the shooting game that uses the solid projectile and design.

The specific embodiment

Penetrate the physical analysis of a liquid bullet by air

The utility model can make discrete liquid bullet penetrate air, and minute quantity is only arranged or do not accompany along with drop.Because aloft the bullet of the liquid state of flight is rare in nature greater than raindrop obviously, therefore, this effect is unique.Therefore, description of the present utility model is to begin the physical property argumentation of the liquid of flight aloft.

Be known that the decline along with raindrop, if their accumulations are too much, then they can split into less drop.In fact, people have studied and have drawn the maximum sized formula that calculates the water droplet that falls to the ground.Variable in these formula depends primarily on the shape of water droplet, the amount of water droplet, the speed of water droplet motion and the density of the air that water droplet passes through.Generally speaking, along with the speed of water bullet motion through air increases, the air pressure that is resisted against the front of water finally can make it be flat and split into less drop.These less drops may continue to flatten and divide, up to the enough little underspeed that makes their final free-fallings of the drop that is produced so that till their divisions.

Preferred embodiment of the present utility model can be launched the cylindrical water bullet that volume is about 2 cubic centimetres.When this bullet motion during, make it gather to become to a certain degree sphere at first against the air pressure of its front and inside attraction in the liquid itself through air.Yet,, it flattened or divide against the air pressure of its front if the liquid bullet continues to move with too high speed.

The experiment of carrying out with model of the present utility model shows that when the volume of water bullet increased, the maximal rate of bullet division reduced.On the contrary, when the volume of water bullet reduced, the maximal rate of bullet division increased.In another experiment, by changing the speed that the water bullet flies aloft, under sea-level atmosphere pressure, 2 cubic centimetres the maximal rate of cylinder 2 before division is about 22 miles per hours.This information is utilized for the Model Selection driving spring that just discharges the liquid bullet under 22 miles per hours.

Now, our notice has turned to such problem, that is, single liquid bullet is quickened and discharge in the air, and it almost or is not fully accompanied with drop is arranged.This problem can be passed through, and makes each molecule in the liquid move and be kept perfectly when realizing that the liquid bullet discharges and solve with identical speed and direction.If satisfied this condition, just do not have again other power to make the bullet division outside the deacration pressure.Yet,, that is to say that if its molecule moves with different speed, liquid may split into the different drop that moves along different directions if the liquid bullet is d/d words under turbulence state.First problem that the utility model solves is the liquid bullet is quickened and not cause turbulent flow.Second problem that overcomes is that its release is not caused turbulent flow.

The utility model is when bullet is retained in the fixation wall of container it to be quickened at the solution of first problem.Because wall of a container is rigidity, seam crossing seals, and in bullet or do not have compressible fluid such as air afterwards, therefore, does not have the activity space of fluid molecule, and can not cause turbulent flow like this.Even open the front of container, fluid molecule can not trend towards flowing along that direction yet, and its reason is that acceleration is pushed these fluid molecules toward the rear portion.Therefore, when the liquid bullet had been accelerated and has prepared to discharge from container, all fluid molecules can move in a similar direction with same speed.

Solution to second part of this problem is, how to discharge the liquid bullet and do not cause turbulent flow, the utility model proposes two measures.First measure be, release is positioned at the vacuum at bullet rear portion after quickening to stop, and like this, liquid can freely leave container.Second measure be, is configured to the sidewall of container basic parallel with the container acceleration direction.This will make the liquid bullet molecule that contacts with chamber wall can not change their speed or direction and leave container substantially.

Figure 1A, 1B, 1C and 1D show an embodiment of the present utility model, and Fig. 2 A, 2B, 2C and 2D show second embodiment, and Figure 12 A, 12B and 12C show the 3rd embodiment.These three embodiment have all utilized above-mentioned principle to launch the liquid bullet.

Can quicken and discharge first kind of device of liquid bullet

Referring now to Figure 1A and Figure 1B, wherein show the stereogram and the sectional view of " mobile containers and the mobile piston liquid bullet transmitter " 15 of the position that is in " preparing emission " respectively, " preparing emission " position is called as the phase I.In this embodiment, transmitter 15 comprises a liquid container 16, and the sidewall of container 16 is parallel with the longitudinal axis 20 of container 16, and it also comprises an opening that is positioned at axis 20 right-hand members and one second opening that is positioned at axis 20 left ends.The opening of left end is by fixed piston 17 sealings, in case leak of liquid.Liquid bullet 18 is positioned at container 16.Be this orientation, the vacuum that is positioned at liquid bullet 18 rear portions and sidepiece trends towards preventing that bullet from leaving from the right openings of container 16.

In the second stage that is called as the utility model running, container 16 is applied an active force, container is quickened along axis 20 and with the direction shown in the arrow of Fig. 1 D.Because piston 17 and liquid bullet 18 are kept by container 16, so they will quicken with the speed identical with container 16.Therefore, in this stage, these three assemblies all will be with identical speed motion.

In the phase III, container 16 striking blocks 19.This will make container 16 slow down, and piston 17 and liquid bullet 18 then continuation move with their previous speed.

Fig. 1 C and Fig. 1 D show the quadravalence section---and the position of " battery has fired just ", wherein liquid bullet 18 is released and flies out.When this point, container 16 slows down, and piston 17 and liquid bullet 18 have moved forward together, till the left end owing to the back axle head striking container 16 of piston 17 slows down travelling forward of piston 17.Because when this happens, the tip of liquid bullet 18 and piston 17 is positioned at outside the container 16, and therefore, the vacuum of the liquid bullet 18 of only withing a hook at the end is positioned at the place, tip of piston 17.In this position, the liquid bullet can break away from moving slower piston 17, and wherein resistance is minimum relatively.If desired, the shape of the tip of piston 17 or leading edge can be configured to: friction and interference to liquid bullet 18 when liquid bullet 18 breaks away from are minimum.

At five-stage, piston 17 is got back to the home position described in the phase I, and a new liquid bullet is loaded in the container 16.Can restart the emission circulation this moment.

Can quicken and discharge second kind of device of liquid bullet

Fig. 2 A and Fig. 2 B show stereogram and the sectional view of second embodiment of the present utility model respectively.In this embodiment, the left end of container 24 was opened in the moment of slowing down.Be illustrated as " the liquid bullet transmitter that open at mobile containers and rear portion " 22 that is in " preparing emission " position, " preparing emission " position now is called as stage A.Transmitter 22 comprises liquid container 24, and the sidewall of container 24 is parallel with the longitudinal axis 23 of container 24, and transmitter 22 also comprises an opening of the right-hand member that is positioned at axis 23 and one second opening that is positioned at the left end of axis 23.In case its leakage, and valve 25 can rotate around valve axis 43 opening of left end by valve 25 sealing.The inertia of valve 25 is, the product of the quality of the valve 25 on the distance that the product of the quality of the valve 25 under the distance of the mass centre of the valve under the valve axis 43 25 and valve axis 43 will obviously surpass valve 25 mass centres on the axle 43 and the valve axis 43.One liquid bullet 26 is shown in the container.In this position, be positioned at the rear portion of liquid bullet 26 and the vacuum of sidepiece and trend towards preventing that the liquid bullet from leaving from the right opening of container nest 24.

In running, in the present embodiment stage B, container 24 is applied an active force, container 24, valve 25 and liquid bullet 26 are quickened towards the right side along axis 23.Under the acceleration situation, owing to the moment of the quality 25 of the valve under the valve axis 43 produces the clockwise moment around valve axis 43 greater than the moment on the axis, thereby valve 25 more closely is pressed against on the left opening of container 24, seals with anti-leak thus.In this stage, container 24, valve 25 and liquid bullet 26 all will move with identical speed on any point.

At stage C, container 24 slows down after block 27 in striking.Simultaneously, the bigger moment of quality will make it open by counterclockwise rotation under the axis of valve 25, and the inertia of liquid bullet 26 will make its continuation advance forward.Because only have the vacuum that keeps liquid bullet 26 to be positioned at the surface of valve 25, therefore, liquid bullet 26 will break away from the valve 25 of withdrawing, and resistance, the turbulent flow being out of shape or causing are less relatively.If desired, the shape on the surface of the valve 25 that contacts with liquid bullet 26 can be configured to make minimum friction forces, and can allow liquid bullet 26 reposefully, interference-free breaks away from as far as possible.

Fig. 2 C and Fig. 2 D show stage D---the position of " battery has fired just ".Container 24 has slowed down, and valve 25 is opened, and liquid bullet 26 has been launched along the direction of arrow.

In stage E, take measures to make valve 25 to rotate back in the home position described in the stage A, new liquid bullet is loaded in the container 24.Can restart the emission circulation now.

Can quicken and discharge the third device of liquid bullet

Then, with reference to Figure 12 A, wherein show the sectional view of " the liquid bullet transmitter of fixed container and mobile piston " that be positioned at " accelerating piston " position, the position of " accelerating piston " is called as the phase I.In the present embodiment, transmitter 22 comprises a fixed container 67 that is used for liquid, and the sidewall of container 67 is parallel with the longitudinal axis 68 of container 67, and it also comprises an opening that is positioned at axis 68 right-hand members and one second opening that is positioned at axis 68 left ends.The opening of left end is by fixed piston 17 sealings, in case leak of liquid.Liquid bullet 70 is shown in the container 67.Be this orientation, be in the left side of liquid bullet 70 and the vacuum of sidepiece and trend towards preventing that bullet from leaving from the right opening of container 67.

In the second stage of running, container 67 is maintained fixed, and piston 69 is applied an active force, thereby piston 69 is quickened along axis 68 and with the direction shown in the arrow.Because liquid bullet 70 is kept by container 67, so bullet is stressed and quicken with the speed identical with piston 69.Therefore, in this stage, two assemblies all are to move with identical speed.

Figure 12 B shows the position of " release plunger ".In this phase III, acceleration is interrupted, thereby allows piston 69 and liquid bullet 70 to continue expedite moving with constant speed.

At last, Figure 12 C shows the quadravalence section---and " stopping piston " position, in this position, liquid bullet 70 has been released and has flown out along direction shown in the arrow.In this point, the travelling forward of piston 69 owing to back axle head 71 strikings of piston 69 left part to fixed container 67 stops.This throws off liquid bullet 70 and piston 69, and continues unhinderedly motion.

In five-stage, piston 69 is recovered to the home position shown in the stage g, and a new liquid bullet is loaded in the container 67.At this moment, just can restart emission has circulated.

The emitter assemblies of preferred embodiment

Fig. 3 shows the side isometric view of the preferred embodiment of the present utility model of the position that is in " preparing emission ", and this is a kind of water bullet transmitter 28, has wherein removed Left-Hand Panel.

Fig. 4,5 and 6 shows stereogram, front view and the sectional view of the emitter assemblies 29 that is in " preparing emission " position respectively.Assembly 29 comprises a container 30, a water bullet 31, a piston 32, a compression spring 33 and a flexible drive band 34.These are the main activities parts that are used to make 31 runnings of emission water bullet.

Fig. 8,9 and 10 shows stereogram, front view and the sectional view that is in the emitter assemblies 29 in " battery has fired just " position respectively.Piston 32 has been parked in its position forward, and its tip is outstanding from container 30.Water bullet 31 breaks away from the tip of piston 32, and flies in air along the direction of arrow of Figure 10.

Referring now to Fig. 3, an opening 36 is arranged in the front of housing 35, after the emission, water bullet 31 can be discharged by this opening.Assembly 29 remains on housing 35 by the recess 56 on each side that is positioned at container 30, and container 30 cooperates with housing track 37 and can be free to slide thereon, make assembly 29 thus in housing 35 about back and forth reciprocating motion.

Shown assembly 29 is in the position of " preparing emission ", and rotating band 34 extends tension between container 30 and housing 35 front portions.Although rotating band 34 has applied a power assembly 29 is spurred forward, assembly 29 can not move owing to the restriction of brake component 38, and brake component 38 abuts against arm 39 lockings of piston 32.

The safety door assembly of preferred embodiment

Fig. 3,7 and 11 shows the part of safety door assembly.Safety door 40 can prevent that the people from inserting an interim projectile of preparing in the container 30, perhaps prevents in its path that is in assembly 29, guarantees only to have liquid just can be launched thus.

Referring now to Figure 11, this accompanying drawing is the exploded perspective view of part of the safety door assembly that is in " battery has fired just " position, and the part that illustrates is respectively door 40, door-hinge line 65, the spring 41 that pushes, flexible door return spring 42, assembly 29 and a vessel side protuberance 64.In operation, when container 30 ran to the front of transmitter 28, protuberance 64 arrived striking and promotes spring 41.When protuberance 64 continued to move forward, door 40 centered on door-hinge line 65 Unscrews by the power of protuberance 64, and this power is to be transmitted against the rear portion of door 40 by the spring 41 that pushes.When door 40 was opened, water bullet 31 can unhinderedly pass through opening 36.Stop when elasticity locking strip 63 closes having travelled forward of assembly 29, then when the right-hand member of housing 35 retracts assembly 29, promotes the pressure that spring 41 is applied on the door 40 and be released, and spring 42 makes door 40 closures apace.

The advantage that a kind of configuration structure provided like this of components is, promoting length, spring rate and the initial tension of spring 41 and length, spring rate and the initial tension of return spring can regulate, thereby door 40 is only stayed open in the moment of the water bullet 31 that quickens by door 40 zones.The extremely short period of this section can prevent that the someone from can react the door 40 that will be shown in an open position fast enough and catching door and keep door to open, subsequently a projectile that temporarily provides is inserted in the transmitter 28.Second advantage be, when being in its resting position, can not opening door 40 and insert an interim projectile of preparing, and its reason is, do not have enough spaces to make finger insert in the door 40 between housing 35 and the door 40 and thus it is drawn back.Explanation once more, this can prevent the insertion subsequently of the interim projectile of preparing.The 3rd advantage be, door 40 can prevent in people's the path of finger plug-in package 29, and prevent to be got to by assembly 29 thus.The 4th advantage is, if finger inserts in the opening 36, perhaps is held against the front portion of door 40, when transmitter 29 is opened fire, can not experience tangible impulse force.Its reason is, the spring rate that promotes spring 41 is enough low, and like this, even when protuberance 64 strikings during to the opposed end of promotion spring 41, it also only can apply a less power by opposite house 40.

Charging-the relieving mechanism of preferred embodiment and water conveying system

Also show a kind of water transport loading system among Fig. 3, this delivery system can be transported to water the container 30 from water tank 44.In a complete running circulation, water is successively from water tank 44, enter the inner chamber of the pump housing 47 by suction pipe 45, by simple tension valve 46, by unidirectional transfer valve 48, then enter in the inner chamber of container 30 by delivery hose 49.It is noted that the inner chamber of container 30 is equipped with water, and container 30 tilts towards Open Side Down, by vacuum seal that is positioned at the container chamber rear portion and the sealing that is provided by valve 48, the water of loading will be restricted and can not flow container.Valve 48 is by its initial opening pressure sealing, and in the situation of preferred embodiment, this opening pressure has surpassed the pressure of 10 inchess of water(in H.The experiment of the model of present embodiment shows, when these seal when intact, if the diameter of chamber opening less than about 0.32 inch, the water of loading can the flow container chamber.

Referring again to Fig. 3, pump rod 50 links to each other by the pump rod trunnion that is positioned at the pump rod left end with housing 35.Pump piston 52 links to each other with bar 50 by pump piston trunnion 53.In the stage of " transporting water ", bar 50 is shifted to the right side along with assembly 29 and is risen, thereby bar 50 is rotated counterclockwise around trunnion 51.This enters driven plunger 52 in the inner chamber of the pump housing 47, thereby water contained in the described inner chamber is pushed in the flexible pipe 49.When this happens, can stop water to pass through valve 46 moves in the pipe 45.When water conveying system had poured into, a water bullet that equates with the water yield that inner chamber from the pump housing 47 shifts out was pushed in the container 30.In stage, pump spring 54 catch bars 50 make bar 50 clockwise rotate around pin 51 in " suction ".Like this, a certain amount of water since vacuum from water tank 44, suck in the pump housings 47 by pipe 45 and valve 46.When this happens, valve 48 can stop water to pass through in the flexible pipe 48 suction pump housings 47.

The emission circulation of transmitter

A slide handle 55 is installed in housing 35 times, and what utilize in the present embodiment is the recess of the sidepiece of the handle 55 that cooperates with track in the housing 35.Track is not shown.This structure can be freely slidably reciprocates handle 55 along the direction of motion identical with assembly 29.Following order has been described a complete emission circulation, supposes that wherein a water bullet just is launched out:

Circulation rests on the rear portion that the left side of housing or front portion and handle rest on housing 35 from assembly 29.The operator pushes handle 55 to front portion from the rear portion of housing 35.In that, by brake component trunnion 57 pivot in handle 55 rotate and by a brake component spring 58 stably to the brake component 38 of upper offset bottom slid underneath at the arm 39 of piston 32, and go up to recovery rapidly subsequently, cooperate with arm 39 in its left distal end.

Then, the operator draws handle 55 to the right, and perhaps the rear portion towards housing 35 spurs.When this happens, front portion and the flexible drive band 34 between the container 30 that is connected housing 35 further strained.In addition, when handle 55 is shifted to the right side, following action will take place successively:

Container 30 is held in place, and piston 32 is shifted to the right side, up to the head of piston 32 with till flange 60 in the container 30 contacts.Fig. 6 shows this orientation of each components.Referring again to Fig. 3, then the right side is also shifted in container 30 beginnings, and is spurred by the head of piston 32.When it ran to the right side, container 30 was in the basal sliding of bar 50, thereby lever 50 is risen.Bar 50 rises piston 52, and piston 52 will promote water and enter in the container 30 by valve 48 and flexible pipe 49 from the pump housing 47.After this, the surface 61 (the bottom rear side as housing 35 is shown) that housing 35 has certain angle promotes brake component 38 downwards, thereby arm 39 and piston 32 are discharged, and makes the flexible drive band spur assembly 29 forward thus.

Then, container 30, piston 32 and water bullet 31 all pass through rotating band 34 and quicken towards a left side.Though this acceleration can make the pressure in the flexible pipe 49 increase, and can prevent that sealing passes through in valve 48 and valve 46 reflow tanks 44.Pump spring 54 promotes the present bar 50 that is not supported downwards, thereby in the water suction pump housing 47 that will load in addition.Along with the front of assembly 29 arrival housings 35, the protuberance 62 striking locking strips 63 of container bottom, thus container 30 is slowed down, and piston 32 and water bullet 31 will continue unhinderedly operation.

Then, piston 32 moves forward in container 30, and till piston slowed down when spring 33 is arrived in arm 39 strikings, its medi-spring 33 was mounted in the container 30.With reference to Figure 11, approximately at the same time, protuberance 64 strikings that are positioned at the container on the right side of container 30 are to the left end that promotes spring 41.Door 40 is by being pushed open against the power that promotion spring 41 applies by sidepiece protuberance 64.When being in this point, Fig. 7,8,9,10 and 11 shows the position of all constituents of present embodiment.The tip of water bullet 31 and piston 32 all is in the outside of the wall of container 30.Because spring 33 slows down piston 32 water bullet 31 is slowed down, the inertia of water bullet 31 promotes it and breaks away from the piston 32 of operation more slowly.When this happens, owing to make slip away the gradually tip of piston 32, the rear portion of water bullet 31, the smooth conical tip 32 of piston 32 helps anti-sealing bullet 31 to break away from when discharging.Impact when reducing piston striking container 30, spring 33 also help to make water bullet 31 to go out and unlikely cracked.Like this, water bullet 31 just can have been launched.

At last, locking strip 63 ends the full cut-off far away that travels forward of container 30 and piston 32, and they rear portions towards housing 35 can be retracted by the spring force of locking strip 63.Thus, door promotion spring 41 is released against the door applied pressure and comes, and spring 42 makes door 40 closures.Then, the built-up section of all motions has all stopped getting off, and the operator then can move forward slide handle once more, thereby begins another time emission circulation.
