Description

The present invention relates to a balloon bulb, and more particularly to a balloon bulb that emits light by attaching a light emitting diode to the balloon.

At present, general balloons have a variety of complexions, and are ideal for enhancing the atmosphere of pleasure for activities such as holidays and banquets. However, in the case of nighttime outdoor activities, balloons cannot emit light. Can't liven up the atmosphere of pleasure.

A main object of the present invention is to provide a light bulb for a balloon that can enhance a pleasant atmosphere by causing the balloon to emit light in the case of outdoor activities at night.

The invention of the present application made to achieve the above object has one cylinder, and the cylinder has one electric lamp attached to the upper end thereof, the bottom thereof is hollow, and a knob is provided on the inner peripheral surface of the bottom. A spiral for screwing is provided, and the cylinder is divided by a partition piece installed at the center, the upper part accommodates the negative anode terminal of the electric lamp, and the cathode terminal penetrates the partition piece to partition the cylinder. Contacted with the cathode of the battery installed under the piece, the anode terminal connected in series with one resistor and connected to a metal ring installed on the periphery of the lower surface of the partition piece through the periphery of the partition piece, Two batteries are attached under the partition piece, the upper battery is covered with a thermoplastic sleeve, the two batteries are tightly wound with a metal spring, the other battery is covered with the other thermoplastic sleeve, and the metal Battery with the lower end of the spring at the bottom Since the metal surface (anode) is wound and the upper end of the metal spring is connected to the metal ring, the anode terminal is electrically connected to the metal surface of the battery below, and the cathode terminal is connected to the cathode of the battery above An electrical connection is made, and a protrusion is provided on the upper end of the knob. After firmly tightening the knob, the battery with the protrusion is pushed upward, so that the cathode of the upper battery becomes the cathode. Since the metal spring is in close contact with the terminal and the metal spring is in close contact with the metal ring, when the bulb emits light and the knob is loosened, the elastic bias of the metal spring is reduced and Since the cathode of a certain battery does not come into contact with the cathode terminal, the gist of the present invention is that it is a balloon bulb characterized in that the bulb does not emit light.

In the invention of the present application, a plurality of through holes are formed in a peripheral edge of the partition piece that contacts the cylinder, a plurality of through holes are formed in a main body of the partition piece, and a plurality of through holes are formed at the upper end of the knob. When the through hole is opened and the user blows air through the mouth into the hollow part under the knob, the air flows through each through hole, and the outer periphery of the cylinder is covered with a rubber sheet, The rubber sheet covers the through hole in the wall surface of the cylinder in an airtight manner when air is not blown, and when the air is blown, the air blows out through the through holes and pushes up the rubber sheet. The gist is that it is a balloon light bulb according to Item 1.

The gist of the present invention is that it is a light bulb for a balloon according to claim 1 or 2, wherein the light bulb is a light emitting diode.

According to the balloon light bulb according to the present invention, even in the case of night outdoor activities, the atmosphere of pleasure can be enhanced by causing the balloon to emit light.

Hereinafter, preferred embodiments of the present invention will be described in detail with reference to the accompanying drawings.

First, refer to FIG. The balloon light bulb according to the present invention has one cylinder 1, and the cylinder 1 has one light emitting diode 2 attached to the upper end thereof, the bottom thereof is hollow, and the knob 3 is provided on the inner peripheral surface of the bottom. A spiral for screwing is provided.

The cylinder 1 is divided by a single partition piece 11 (generally using a printed circuit board) installed in the center, the upper part accommodates the negative anode terminal of the light-emitting diode 2, and the cathode terminal 21 connects the partition piece 11. The anode terminal 22 penetrates through the periphery of the partition piece 11 in series with one resistor 23, and contacts the cathode of the battery installed through the partition piece 11 and passes through the periphery of the partition piece 11. Connect to the metal ring 112 (or metal circuit on the printed circuit board) to be installed.

Two batteries 13 are attached under the partition piece 11, the upper battery is covered with a thermoplastic sleeve 15, the two batteries are tightly wound with a metal spring 12, and the other batteries are covered with another thermoplastic sleeve 16. cover. Since the lower end of the metal spring 12 is wound around the metal surface (anode) of the battery below and the upper end of the metal spring 12 is connected to the metal ring 112, the metal surface of the battery with the anode terminal 22 below ( The cathode terminal 21 is electrically connected to the cathode of the battery on the upper side.

One protrusion 31 is provided at the upper end of the knob 3, and after the knob 3 is firmly tightened, the battery with the protrusion 31 is pushed upward so that the cathode of the battery at the upper side becomes the cathode terminal 21. Since the metal spring 12 comes into close contact with the metal ring 112, the light bulb emits light. When the knob 3 is loosened, the urging force of the metal spring 12 is reduced and the upper battery cathode does not come into contact with the cathode terminal 21, so that the light bulb does not emit light.

A plurality of through holes 14 are formed in the periphery of the partition piece 11 that contacts the cylinder 1, a plurality of through holes 111 are formed in the main body of the partition piece 11, and a plurality of through holes 111 are formed at the upper end of the knob 3. The through-hole 32 is opened. When the user blows air through the mouth into the hollow portion 33 below the knob 3, the air flows through the through holes 32, 111, and 14.

Further, since the outer periphery of the cylinder 1 is covered with the rubber sheet 4, when the air is not blown, the rubber sheet 4 covers the through hole 14 in the wall surface of the cylinder 1 in an airtight manner. The rubber sheet 4 is pushed up through the through holes 32, 111, and 14 to push up the rubber sheet 4.

Further, as shown in FIG. 2, after the cylinder 1 is attached to the opening portion of the balloon 5, the cylinder 1 is fixed to the opening portion of the balloon 5 by dust ring, and the user uses the mouth to place the cylinder 1 under the knob 3. When air is blown into the hollow portion 33, the air flows through the through holes 32, 111, and 14, pushes up the rubber sheet 4 and expands the balloon 5. When the balloon 5 expands to a predetermined degree, the user stops blowing air and the rubber sheet 4 airtightly covers the through hole 14 in the wall surface of the cylinder 1 so that the air in the balloon 5 does not leak. . Then, the balloon bulb according to the present invention is completed.

The through holes 32, 111, 14 and the rubber sheet 4 need not be used. In this case, the user may blow air into the balloon 5 to expand it, insert the cylinder 1 into the opening part of the balloon 5, and fix the cylinder 1 to the opening part of the balloon 5 by dust ring.

Thus, although the present invention has been described with reference to specific examples, the examples are for illustrative purposes only and are not intended to limit the present invention, and common general knowledge in this field. Those skilled in the art will recognize that changes, additions, or deletions may be made to the embodiments disclosed herein without departing from the spirit and scope of the present invention.
