Description

DETAILED DESCRIPTION OF THE INVENTION (Field of Industrial Application) The present invention relates to a smoke-generating device, and more particularly to a smoke-generating device mainly used for entertainment, such as baseball balls and golf balls, which can emit smoke and fly when hit with force.

(Prior Art) Smoke-emitting balls such as baseball balls and golf balls that can emit smoke have been known from, for example, Japanese Patent Publication No. 13684/1984. This known smoke ball has an igniting powder loaded in the center, and the space between the outer shell of the ball and the igniting powder is filled with the igniting powder, and when the outer shell of the ball is struck, the particles of the igniting powder rub against each other and ignite. The flame spreads to the smoke powder, which emits smoke from the multiple holes in the ball's outer shell, trailing a beautiful trail of smoke as it flies.

(Problem to be Solved by the Invention) However, when this kind of known smoke ball lands close to combustible materials such as dry grass, the smoke hole provided in the outer shell of the ball emits hotter molten material (combustion of pyrotechnic powder). (molten material) could flow out and cause a fire.

(Means for Solving the Problems) In the present invention, the combustion melt of the pyrotechnic charge does not flow out from the smoke hole, and the heat absorption is good, so cooling is relatively easy and there is no risk of fire. Our goal is to provide you with no fuming tools.

According to the present invention, in a smoke generating tool comprising an outer shell having at least one smoke generating hole, and a smoke generating agent and an ignition charge loaded inside the outer shell, a metal mesh covering the smoke generating hole is provided. Provided is a smoke-generating tool, characterized in that: is provided on the inner wall of the outer shell.

(Example) Hereinafter, the present invention will be described with reference to the accompanying drawings with reference to an example thereof. A golf ball 10, which is shown with reference numeral 10 in the accompanying drawings, shows the application of the smoke generating device of the present invention to a golf ball. The outer shell is composed of two semicircular spherical members 11 and 12,
The shoulder portions 13 are provided and bonded with adhesive or the like so that they can fit together. The outer shell 11° and 12 are 1 in order to withstand strong blows.
Manufactured from strong synthetic rubber. A plurality of smoke holes 14 are bored in the outer shell 11,12. The smoke hole 14 is made of thin paper 21
The thin paper 21 is the same as a golf ball! It is preferable to paint it in the color of

At the center of the golf ball 10 is a pyrotechnic charge 15. For example, a mixture of 70 to 80 wt % lead tetroxide and 20 to 30 wt % silicon iron is dissolved in a celluloid amyl acetate solution, adhered to the surface of a fine stone and dried, and then packaged and placed in a polyethylene bag 16. A smoke generating agent 17 is similarly packaged in a polyethylene bag 18 and arranged around the igniting agent 15. pyrotechnic powder 1

11-21% In the present invention, metal meshes 19 and 20 covering the smoke holes 14 formed in the outer shells 11 and 12 of the golf ball 10 are disposed in contact with the inner walls of the outer shells 11 and 12, respectively. The arrangement of the metal mesh 19, 20 is extremely important for safety, as will be explained below. That is,
When the golf ball 1o was hit hard with a golf club, the impact ignited the pyrotechnic powder 15, ignited the smoke powder 17, tore the thin paper 21, and emitted smoke from the smoke hole 14, leaving a trail of smoke and flying for several seconds. After that, land. Metal mesh 19.20
If no
If there is combustible material such as dry grass at the point where the water flows out from No. 4 and lands, the high temperature may cause a fire. In the present invention, the metal mesh 19, 20 is provided, so that the combustion melt can be transferred to the smoke hole 14.
There is no risk of leakage to the outside. Moreover, the metal nets 19 and 20 absorb heat and cool down relatively quickly. It is desirable that the metal mesh has 100 to 10 meshes. 10
If the mesh is finer than 0, it will be difficult for the smoke to pass through the metal mesh and it will adhere to the metal mesh, and the attached smoke may become large particles that will drip off and lose the smoke generation effect. It may not be possible to prevent leakage. Further, it is desirable for the metal mesh to cover 273 or more of the total surface area of the inner wall of the outer shell 19, 20 from the viewpoint of cooling effect. The material of the metal mesh is not particularly limited as long as it is heat resistant; for example, it can be made of galvanized iron.

(Effects) The smoke generating tool of the present invention has no fear of fire outbreak and can be used safely because it cools down quickly.
