Description

Water arrow device

Technical field

The utility model relates to a kind of amusement appliance, and especially water relates to a kind of Water arrow device.

Background technology

At present, general water arrow (or being referred to as water rocket) mainly is with a certain amount of water of packing in the plastic bottle, utilize inflator to squeeze into air, make and be full of gases at high pressure in the plastic bottle, utilize releasing device to unclamp clamping then to the plastic bottle head, make the gases at high pressure in the plastic bottle be released, according to the reaction force principle, plastic bottle such as rocket fly out immediately.At present the water arrow of this class between emitting structural and water arrow and emitting structural and aspect such as overall structure all have operation inconvenience and uneasy congruent problem, thereby reduced entertainment interest, present in addition water arrow is difficult to carry, and so also brings inconvenience to the operator.

Summary of the invention

The purpose of this utility model is exactly the defective that overcomes existing water arrow, and a kind of improved Water arrow device is provided, and by its rational design, can make that its handling safety is reliable, is easy to carry.

Before describing the technical solution of the utility model, the principle of water arrow emission will be described simply according to Newton's law.

Liquid and gas are referred to as fluid.The smaller volume of gas when certain pressure is put on gas, density increase, thus with gas compressible fluid.The volume of liquid did not change when certain pressure was put on liquid, thus with liquid incompressible fluid.The part of open air under pressure, moment can produce very large energy, and gas flows out rapidly thereupon.Otherwise because of the incompressibility of liquid, liquid slowly flowed out toward lower when pressure was put on liquid.The water arrow produce huge energy when well having coordinated gas and flowing out but the time too short, little but the characteristic that the time is long of produce power when liquid flows out.In the plastic bottle of pouring water, irritate compressed air.Air molecule can not flow out, and air puts on pressure the wall and the water surface of plastic bottle.Open bottle cap this moment, and instant water sprays from bottleneck.Press the principle plastic bottle of Newton's third law " active force is identical with reaction force " this moment with the direction opposite, onesize momentum flight with the water injection direction.Should notice that water can not too much can not be very little this moment.It is too many that water is irritated, and influences flying distance because of the plastic bottle body weight is too big.Time of influence very little that water is irritated and influence flying distance.With the 1.5L plastic bottle is example, irritates 350～400ml and could ensure maximum flying distance.

After understanding water arrow emission principle, the technical scheme that the utility model is implemented on above-mentioned purpose is described below, Water arrow device provided by the utility model includes water arrow, water arrow emission member and water arrow matrix, wherein said water arrow is a plastic bottle structure, and a certain amount of water is housed in its plastic bottle; Described water arrow emission member is by the air input pipe, inner joint, external tapping, iron ball, the water arrow is supported platform, angle demodulator, control assembly and emission element fixed head are formed, wherein the air input pipe is divided into thickness two parts, thin portion one end of air input pipe is inserted in the inlet of plastic bottle, and in thin portion, rubber seal ring is installed, and its thick portion is assembled in the inner joint, the port of the thick portion of air input pipe is mounted with a kind of valve inside element, this valve inside connects an air pump, inner joint is fixed on the emission fixed part by the interface hold-doun nut, the external tapping outer rotatable is assemblied in inner joint, its rotating range is 15 to 20 degree, constitutes the member that rotation suppresses and launch the water arrow by iron ball and external interface; Also being fixed with one on the emission fixed part is used for the held water arrow and induces the water arrow of water arrow emission to support platform, on the emission fixed part, also dispose an angle demodulator simultaneously, this adjuster can be regulated the angle between emission fixture and the water arrow matrix, described control assembly links in external tapping, its control assembly is a bicycle cable rim brake formula structure, can make its rotation external tapping by backguy; Described water arrow matrix is by the shank that connects front-wheel and trailing wheel and be connected front-wheel and the neck of transmitting station constitutes, wherein front wheele part connects neck and shank, collapsible when carrying, extensible effect during use, and also have the effect of supporting emission member and neck weight.With the front-wheel is that central neck portion is fixed on front-wheel, axle by front-wheel can be fixed two shanks, with between the shank that links to each other of wheel connecting plate is arranged, connecting plate will be fixed from neck fixed axis that extends and the fixed axis that extends from shank, support the weight on top simultaneously, the position of trailing wheel portion is at the tail place of two shanks.The main material of wheel is made of rubber, and main effect is to prevent to be pushed.Because therefore such formation of water arrow matrix just makes its water arrow have and carries and function easy to use.At folding state water rocket body neck is upwards lifted 40 degree.To push abduction 40 degree afterwards to, and can make two shanks and cervical fixation like this on connecting plate.To receive in two legs when using the back folding, neck presses down and gets final product, the safety when making operation could ensure use in order.

An amount of water is irritated into ready-made water arrow, with the air input pipe reeve water inlet of emission part.Two rubber seal rings are enclosed within the adverse current that the air input pipe can be prevented sealing, also can make air enter water arrow inside by air pump, and the transmit direction of water arrow the time is induced in emission.The air input pipe that is inserted in the water arrow is inserted in as far as possible the inner joint of emission member.When fully in conjunction with the time with external tapping rotation 15～20 degree control water arrows, the water arrow is flown out.By angular adjustment nut adjusting angle and distance.Regulating the back tightening nuts fixes.The valve inside that links to each other with the air input pipe utilizes air pump to pass through air input pipe injection air, and the air of water arrow is pressed when reaching 70～80ppm and stopped.Also can above this scope or less than this scope.Air setting-out arrow desire disengaging emission part because of the water arrow.This moment emission part inner joint, external tapping, the anti-sealing arrow of iron ball breaks away from.The contrary direction rotation of the control device that will be connected this moment with external tapping rotation 15～20 degree, the water arrow can fly to target.

Further describe the structure of Water arrow device of the present utility model below in conjunction with accompanying drawing, make its structure and effect thereof had more clearly and understand.
