Abstract

The present invention relates to a rubber balloon air levitation toy capable of driving on a flat surface by reducing friction through the formation of an air layer from the bottom surface using the force of air expelled by the elasticity of the rubber balloon. It is also utilized as an experimental teaching aid for experimenting with and observing friction, action-reaction, and constant velocity motion in school curricula. The present invention relates to a rubber balloon air levitation toy capable of moving by its own power according to the law of action-reaction, equipped with an air injection nozzle (410) that was not present in conventional rubber balloon air levitation toys. It is designed to control whether the injection nozzle (410) is sprayed, allowing for various selective experiments and play. Additionally, it is equipped with an opening/closing valve (300) for operation to make it easy to play with, and an air injection part (500) for easily and conveniently injecting air into the balloon. Furthermore, a truncated cone-shaped balloon insertion part (210') is provided to prevent the inflated balloon from tipping over easily.

Description

Rubber balloon levitation toy with jet nozzle Rubber balloon levitation toy with jet nozzle The present invention relates to a rubber balloon air levitation toy capable of traveling on a flat surface by reducing friction through the formation of an air layer from the ground surface using the force of air expelled by the elasticity of the rubber balloon. It is also utilized as an experimental teaching aid for experimenting with and observing friction, action-reaction, and constant velocity motion, which are part of the school curriculum. The present invention relates to a rubber balloon air levitation toy equipped with an air injection nozzle, which is absent in existing rubber balloon air levitation toys, enabling it to move by its own power based on the law of action-reaction. A rubber balloon air-floating toy called a balloon hovercraft is known on the market, which has a flat surface with one or more exhaust holes formed therein and a balloon insertion part formed on the top surface where the opening of a rubber balloon is inserted while wrapping its outer surface, and an air passage (220) is formed in which the inside of the rubber balloon communicates with the exhaust holes. When air is blown into the balloon and the toy is placed on a flat surface, the air in the balloon escapes through the exhaust holes, and a fine layer of air is formed from the surface, causing it to float. At this time, even a small push causes the toy to move in a straight line. This is because the frictional force is significantly reduced due to the layer of air formed between the surface and the bottom surface of the toy. In particular, rubber balloon air levitation toys are introduced in the elementary school science curriculum to experiment with action-reaction and friction. In addition, Patent No. 10-1049250, "Rubber Balloon Air Floating Toy for Scientific Experiments," filed and registered by the inventor, introduced an air inlet with a check valve to allow the user to comfortably inflate the balloon, and an opening/closing valve to control the discharge of air from the balloon, allowing for easy and convenient operation. In the case of rubber balloon air levitation toys that float due to the elasticity of the balloon, an external force is essential to observe movement as friction with the ground surface is significantly reduced. In addition, the balloons attached to existing rubber balloon air levitation toys have a problem in that they cannot withstand the weight when inflated and easily fall over. As a result, the fallen balloon comes into contact with the ground, causing friction that hinders the movement of the moving balloon. FIG. 1 is a schematic illustration for explaining a rubber balloon air buoyancy toy according to an embodiment of the present invention. FIG. 2 is a cross-sectional view illustrating the principle of air flow and air levitation from a balloon according to an embodiment of the present invention. FIGS. 3a) and 3b) are illustrative diagrams for explaining a spraying unit according to an embodiment of the present invention. FIGS. 4a) and 4b) are cross-sectional views illustrating the interruption of air sprayed through the nozzle (410) according to the nozzle direction of the spraying part according to an embodiment of the present invention. FIGS. 5a) and FIGS. 5b) are illustrative diagrams for explaining a truncated cone-shaped balloon insertion part (210') according to an embodiment of the present invention. FIG. 6 is an illustrative diagram for explaining an air injection part (500) and a check valve (510) according to an embodiment of the present invention. Hereinafter, a rubber balloon air buoyancy toy equipped with a spray nozzle according to the present invention will be described with reference to the attached drawings. The present invention is a rubber balloon air buoyancy toy that moves on its own by utilizing the principle of action and reaction through the force of air coming out of a spray nozzle without applying external force when operated. Referring to FIGS. 1 and 2, an exhaust hole (110) through which air escapes from the balloon is formed on the bottom surface (100) of the lower part of the body (200) of the rubber balloon air buoyancy toy. The size and number of the exhaust holes (110) may vary depending on the load of the rubber balloon air buoyancy toy and the discharge pressure of the balloon (size and thickness of the balloon). Additionally, if the rubber balloon air buoyancy toy has various shapes, the location and number of exhaust holes may vary. For example, the shape of the rubber balloon air buoyancy toy may be various shapes such as a car, a boat, an airplane, or a flying saucer. Depending on the shape, a number of exhaust holes (110) are appropriately arranged on the bottom surface so that the load can be evenly distributed. Furthermore, it is desirable to have a flat surface so that a sufficient air layer (120) can be formed. In this embodiment, the bottom surface is
