Abstract

The utility model discloses a toy flying ball which belongs to flying toys and is made according to the theory of mechanics of flight. The utility model is characterized in that the air can be charged into the latex balloon of the toy flying ball with a charging open, the balloon can fly upwards stably when the air in the balloon spouts from a special designed spout, and euphony can be sent out when the balloon is flying. The utility model has the advantages that the design is novel, the knowledge teaching and the entertainment are integrated together, and the toy flying ball is benefit for developing the intelligence of children.

Description

Toy flying ball

The utility model relates to a kind of jet propelled flying toy---flyball.

At present, the toy of the class of flying both at home and abroad is limited, and domestic relatively successful flying toy has only flying disc toy and helicopter, but gradually loses novelty and entertaining.State is the control line circular flight machine and the telecontrolled aircraft of tiny engine in addition, although interesting, intellectual strong, cost is too high, and the difficulty of enjoying is big, and certain danger is arranged.In addition, great majority flight type toy all requires bigger space, not too is suitable for indoor object for appreciation.Therefore, necessary development of new, interesting strong, cheaply, flight type toy, the especially toy that can both play in indoor and outdoor.

The utility model is a kind of Toy flying ball of can jet flight and sounding.Be characterized in: mix special spout by latex balloon and constitute flying body.Fig. 1 is the outline drawing of Toy flying ball; Fig. 2 is the axonometric drawing of spout; Fig. 3 is the profile of spout shown in Figure 2; Fig. 4 is a kind of version of unidirectional charging connector; Fig. 5 is the spout of band flow deflector; Fig. 6 is the profile of spout shown in Figure 5.

The utility model adopts latex balloon (1) to make the main body of flying toy, with the power source of the elastic deformation energy behind the inflation of balloon own as flight, as shown in Figure 1.Air in the balloon must be from a special spout (2) ejection could guarantee that flyball stably makes progress and fly.Spout is the axially symmetric structure of a hollow, and as shown in Figure 2, respectively there is a small sircle hole at the center of top and bottom, and two annular lip are arranged on sidewall, is used to strengthen tightness and the reliability that spout cooperates with balloon.Spout can be fitted in together with the non-toxic plastic spare of injection moulding processing and form.The weight of spout, internal diameter will be complementary with weight, the tension force of flyball.The tension force deficiency of the little or flyball of the internal diameter of spout, whole balloon just can not fly, if the internal diameter tension force excessive or flyball of spout is big, it is too short that then balloon sprays the time of letting out, the flying speed of balloon is fast, the time of flight is short, and recoil strength is big, and flight is easy to unstability, can not guarantee stably to fly vertically upward.Desirable state be the spheroid of flyball together with the equal retainer shaft of spout to symmetry, gas in the balloon (because the strain of spheroid and the have certain pressure) recoil strength that ejection produces from spout---acts on the top of balloon---and should be a bit larger tham the weight of whole balloon in the mode of total pressure head inside and outside the balloon wall, like this, flight grazioso can stably, slowly make progress behind the flyball sufficient gas, gas spray in ball is most, and flyball descends slowly and lightly again.Fly in the journey last, gas flows through the spout (2) that cavity is arranged can produce euphony.This toy can constantly be inflated (blow or inflate with inflator with mouth), flight constantly, and interest is very strong.

Because this toy is the jet flight toy, and is different with traditional Balloon toy, need inflate frequently, exit, chew so just must design a kind of simple and reliable inflation.Fig. 4 has provided a kind of version that inflation is chewed.The front end (3) that inflation is chewed matches with the spout (2) of balloon, and rear end (5) contact with mouth.Laborsaving when the user is blown, and can let fly away at leisure, in chewing, inflation is provided with a kind of simple check valve (4), and it can stop gas in the ball to be chewed from gas in gas replenishment process to leak out.Had inflation to chew, make this toy much cleaner in use, more civilized, more enjoyment arranged.

Further consider the flight course of flyball toy, if can make flyball when flight around self axis rotation, according to gyro principle, this moment, flyball just had a kind of tendency that guarantees the displacement attitude, when beat takes place, flyball self will produce a restoring moment, thereby has increased the flight stability of toy.The utility model has been done to arrange cleverly to the structure of spout, wall at spout is provided with several flow deflectors with rotation direction (6) axisymmetrically, make air-flow when the ejection spout, become the air-flow of rotation, because the effect of reaction force, flyball will the rotation while flying, the interest that has increased flight stability and enjoied, novel, peculiar, give unlimited reverie, very helpful to the intelligence that edifies children.

Examples of implementation of the present utility model are two-sided wall thickness 0.05mm of balloon, and weight 3.0g, the external diameter of spout are 17, and internal diameter is 6.

Claims

1, a kind of toy balloon of can jet flight and sounding is characterized in that: mix special spout by latex balloon and constitute flying body.

2, toy balloon as claimed in claim 1 is characterized in that described spout is the axially symmetric structure of hollow.

3, toy balloon as claimed in claim 1 is characterized in that having an inflation to chew, and the spout that this inflation is chewed with balloon matches.

4, as claim 1,2 described balloon spouts, it is characterized in that on the inwall of spout structure, can increasing several flow deflectors axisymmetrically with rotation direction.
