Description

AN APPARATUS FOR GENERATING OF SOUND AND ROTATING OF LIGHT BY

AIR FLOW

Technical Field The present invention relates to an apparatus for generating of sound and rotating of light by airflow, in particular, which can generate electricity by itself instead of using disposable batteries to simplify a construction thereof thereby saving fabrication cost as well as to enhance the efficiency of operation thereby enabling a precise operation to be performed.

Background Art

In general, an apparatus for generating of sound and rotating of light by airflow may include a whistle and a horn. The whistle is generally used when a judge announces beginning of a game or points out fowls in a sports game, or when a policeman founds a suspicious person during patrol or traffic violations. In a light-emitting whistle of the prior art shown in Fig. 1, an air inlet 11 of a body A communicates with a central path 12 and an outside path 19, an outside cylinder 20 is connected with the air inlet 11 and contains an inside cylinder 22 arranged therein and coupled with a flared section 27. Air introduced to a central path 13 via the air inlet 11 of the body lights a lamp 17 and is amplified during moving through the outside path 19 to generate clear and sound.

Since therefore described conventional apparatus uses a disposable battery 16, the battery is discharged after a predetermined time period and thus unable to power the lamp. There is also a problem that waste batteries cause environmental pollution.

In the meantime, an air motor is an apparatus for converting the energy of compressed air to rotary kinetic energy. The air motor is utilized in operations such as construction, removal and maintenance of large-sized buildings, grinding work requiring a precise rotation operation, and screw fastening. Fig. 2 is a sectional view of a rotating apparatus capable of emitting light via airflow of the prior art. The rotating apparatus comprises a housing 10, which includes an air inlet

11 formed at one side thereof for receiving air and an air outlet

12 formed at the other side thereof for exhausting air, and an air motor 13 arranged within the housing 10, in which the air motor 13 generates rotation power via inflow air to perform a precise rotation operation. The air rotary tool like this actuates the air motor 13 via inflow air to generate rotation power, which is transferred to a rotary shaft 14 mounted on the air motor 13 so that a machining tip 15 arranged at the leading end of the rotary shaft 14 can perform a precise rotation operation.

However, since the conventional apparatus does not emit light, there is a problem that where a precise operation region is formed irregular or recessed, progress of operation in the region can be hardly measured under a general lamp. As a result, a precise operation cannot be performed in the prior art.

Disclosure of Invention Therefore, the present invention has been made in view of the foregoing problems and it is an object of the present invention to provide an apparatus for generating of sound of light by airflow which can generate electricity by itself instead of using disposable batteries to simplif a construction thereof thereby saving fabrication cost.

It is another object of the invention to provide an apparatus for a rotating of light by airflow which comprises a generating unit for turning rotary blades via air introduced or exhausted with an air motor and a luminous element 30 for emitting light to a point where a machining tip 25 performs a rotation operation to enable the precise operation of an operator.

The sound apparatus comprises a body 120 which includes an air inlet 110 formed at one side thereof, a resonating unit 130 and an air outlet 150 sequentially communicating with the air inlet 110; electric generating means

100 mounted within the body 120 for generating electricity by a fan turned by outflow air; and a luminous element 160 for emitting light by means of electricity generated from the electric generating means 100. It is preferred that the luminous element 160 typically employs a Light Emitting Diode (LED) , which is attached to an upper portion of the body 120 which surrounds the air outlet 150. The electric generating means 100 is fixed to the air outlet 150 via a support 170, and includes a fan and a generator section. The fan is turned freely whereas the generator section is fixed to the support 170. The support 170 includes a passage for allowing airflow.

In the sound apparatus capable of generating light via air flow of the invention constructed as above, introduction of air through the air inlet 110 moves a ball 140 to whistle while turns the fan in the electric generating means 100 to generate electricity, which powers the luminous element 160 to emit light.

Fig. 4 is a sectional view of the electric generating means of the invention. The electric generating means includes a fan 31 turned by airflow and a generator section 50 generating electricity by rotation of the fan 31. One side of a rotary shaft 41 is fixedly inserted into a blind hole 32 formed in a central region of the fan 31, and the other side of the rotary shaft 41 is inserted into the generator section 50. The other side of the rotary shaft 41 is connected to magnets 57 so that the magnets 57 rotate along with the rotary shaft 41.

Fig. 5 is a sectional view of a sound apparatus capable of emitting light via airflow according to an alternative embodiment of the invention. The sound apparatus of the invention comprises a body 120 which includes an air inlet 110 formed at one side of the body 120 and an air outlet 150 formed at the other side of the body 120 to communicate with the air inlet 110; a ring-shaped guide 180 mounted within the body 120 between the air inlet 110 and the air outlet 150 and having an inside passage 185; a diaphragm 187 supportably mounted to the entrance of the inside passage 185 adjacent to the air inlet 110 for vibrating with air introduced via the air inlet; electric generating means 100 mounted within the body 120 between the ring-shaped guide 180 and the air outlet 150 for generate electricity through rotation of a fan which is turned by outflow air; and a luminous element 160 for emitting light by mean of electricity generated from the electric generating means 100. In this embodiment of the invention, introduction of air through the air inlet 110 vibrates the diaphragm 187 to generate sound, which is outputted via an inside passage of the ring-shaped guide 180 to the air outlet 150. Air introduced into the air inlet 110 turns the fan of the electric generating means 100 mounted within the body 120 so that the electric generating means 100 generates electricity, which is applied to the luminous element 160 to emit light.

Fig. 6 is a sectional view of a rotating apparatus capable of emitting light via airflow according to the invention. The rotating apparatus comprises a housing 20 for receiving air via one side thereof and exhausting air via the other side thereof; an air motor 23 mounted within the housing 20 for generating rotation power to precisely turn a machining tip 25; an electric generating unit 26 arranged within the housing 20 for turning rotary blades 28 by inflow or outflow air; and a luminous element 30 for being supplied with electricity from the generating unit 26 to emit light to a point where the machining tip 26 execute a rotation operation.

As a result, likewise to a conventional rotating apparatus, the rotating apparatus of the invention receives air introduced via an air inlet 21 of the housing 20 in an air introduction path 23c of the air motor 23 to create rotation power to the air motor 23. The rotation power of the air motor 23 is transferred to a rotary shaft 24 mounted on the air motor 23 so that the machining tip 25 formed at the leading end of the rotary shaft 24 can execute a precise rotation operation. Unlike the conventional rotating apparatus, rotating apparatus of the invention further comprises a means for emitting light to an operation region to advantageously enhance the working efficiency of an operator as well as enable a precise operation to the operator. Describing this in more detail, after generating rotation power to the air motor 23, air is injected via an air injection path 23b of the air motor 23 to turn the rotary blades 28 of the generating unit 26 mounted on the housing 20 and then exhausted via an air outlet 22.

The generating unit 26 generates electricity via rotation of the rotary blades 28 to energize a luminous element 25 in the form of an LED or bulb, which is mounted outside the housing 20 in a peak region of the machining tip 25. The luminous element 25 emits light so that the operator can perform a precise operation with the rotating apparatus of the invention. Also, the machining tip may comprise a driver for coupling a fine device and a fine structure or a working tool for grinding a minute region.

Fig. 7 is a perspective view of the partially broken generating unit 40 shown in Fig. 6. The generating unit 40 includes a cylindrical housing 42 having rotary blades 41 attached to the surface thereof, a coil 45 arranged on the inner surface of the cylindrical housing 42 in such a manner as to be wound in the form of a cylinder, a stationary shaft 44 fixed to a support 46 extending through the cylindrical housing 42 within the coil 45 to be spaced apart from the coil 45, and a plurality of magnets 43 attached to the stationary shaft 44.

In the generating unit, airflow turns the rotary blades

41 so that the cylindrical housing 42 is turned together.

Rotation of the cylindrical housing 42 also turns the coil 45 attached to the inside face of the housing 40 so that the coil 45 intersects a magnetic flux generated from the permanent magnets 43. As the coil 45 intersects the magnetic flux of the permanent magnets 43, the coil 45 generates electricity based upon Fleming' s right hand rule. Therefore, as the rotary blades 41 are turned by airflow, the generating unit 40 is also turned to generate electricity so that the LED or the luminous element 47 is lighted.

Fig. 8 is a sectional view of a rotating apparatus capable of emitting light via airflow according to an alternative embodiment of the invention. In the rotating apparatus of this embodiment, magnets 43 as shown in Fig.7 are attached to a rotary shaft which is under rotation power of an air motor 23, a cylindrical housing 42 having a coil 45 wound inside the cylindrical housing 42 in the form of a cylinder is fixedly attached to an air motor 23, and the cylindrical housing 42 is extended through the rotary shaft so that the rotation power from the air motor 23 can turn a machining tip 25 and rotary blades 28.

Therefore, the rotation power of the air motor 23 can perform turning operation with the machining tip 24 and operate a generating unit 26 to emit light via a luminous element 30.

Fig. 9 is a sectional view of the rotating apparatus capable of emitting light via airflow according to another alternative embodiment of the invention. In the rotating apparatus of this embodiment, a luminous element 30 is inserted into one side of a flexible bellows tube 62 within an outside housing 54 so that light from the luminous element 30 can be emitted via the other side, of the flexible bellows tube 62 correctly to a point where the machining tip 25 performs a rotation operation. The other side of the flexible bellows tube 62 is projected out of the outside housing 54, extended through the outside housing 54. The flexible bellows tube 62 is flexible to be folded or elongated so that the tube 62 is moved through folding or elongation to emit light correctly to the point where the machining tip 25 performs a precise rotation operation.
