Description

[Detailed explanation of the invention] This invention allows soap bubbles to be continuously fired upward by storing soap liquid in the tubular object in advance without having to soak it in soap liquid one by one.
This soap bubble generator is characterized in that the stored soap liquid does not flow out even if the main body is tilted.

The details will be explained below based on the drawings.

Figures 1 to 3 show a first embodiment of the soap bubble generator according to the present invention.The overall shape of the main body 1 is shaped like a whale, and the soap bubbles are produced when the whale is tidal, as will be described later. It is fired in the same manner as when blowing.

The overall size is about the size of the palm of your hand, and it is made of lightweight plastic material.

An air pipe 2 having a whistle 35 in the middle is passed through the main body 1 which resembles a whale.

One end of the air pipe 2 is a discharge port 3, and the discharge port 3 is opened in a vertically upward position in a recess 4 formed on the upper surface of the main body 1, and the other end of the air pipe 2 is a blow port 5. It is led out from the right end of the main body 1 in the figure (the whale's tail).

A closed tank 7 for storing soap liquid 6 is attached to the upper surface of the main body 1 above the left side of the ejection port 3, and a windmill 9 is rotatably supported near the right side of the ejection port 3.

The soap liquid 6 is replenished into the closed tank 7 by turning the main body 1 upside down.

That is, a replenishment port 11 with a stopper 10 is provided on the lower surface of the main body 1, and soap liquid 6 is supplied from the replenishment port 11 to the closed tank 7 via a communication pipe 12.

A surrounding wall 13 is provided on the outer periphery of the air supply pipe 2 near the emission port 3, and a bottomed annular liquid storage chamber 14 with an open upper surface is formed between the air supply pipe 2 and the surrounding wall 13.

The upper surface of the opening of this liquid storage chamber 14 and the upper surface of the ejection port 3 are set flush.

In the figure, the ejection port 3 is a perfect circle in plan view, and the surrounding wall 1
3 is also made into a perfect circle concentric with the ejection port 3, and the width of the liquid reservoir chamber 14 is set to be uniformly narrow over the entire circumferential direction.

The liquid reservoir chamber 14 is located lower than the sealed tank 7, and both 7 and 14 are connected to each other by a supply pipe 15, so that the soap liquid 6 in the sealed tank 7 flows into the liquid reservoir chamber 14 and the air flows therethrough. The soap liquid 6 is temporarily stored in the liquid storage chamber 14 to prevent it from overflowing to the upper surface of the opening.

A wire actuator 16 is pivotally supported in the upper recess 4 of the main body 1, and the actuator 16 is slid back and forth between the upper surface of the ejection port 3 and the upper surface of the liquid reservoir chamber 14.

The driving means for this actuator 16 is as follows.

First, the air pipe 2 inserted into the main body 1 branches in the middle, and a part of the air blown into the air pipe 2 from the air inlet 5 flows into the branch pipe 17, and this inflow air flows into the windmill 9. can be rotated to the right in FIG.

The windmill 9 is preferably colored colorfully, and its upper half is exposed on the main body 1 for viewing.

Thus, as shown in FIGS. 2 and 3, the rotating shaft 19 of the wind turbine 9 is supported at the front and rear of the upper surface of the main body 1, and the small gear 20 is pivotally supported at the rear end of the rotating shaft 19. large gear 21
the crank 23 to the rear end of the shaft 22 of the large gear 21.
Concatenate.

The actuating element 16 is swingable about a pivot 24 at its front end as a fulcrum, and the crank 23 and the rear end of the actuating element 16 are connected by a connecting rod 25. Both ends are placed on a straight line passing through the axis of the rotating shaft 22, so that the actuator 16 is decelerated by the rotation of the rotating shaft 22.
is designed to swing back and forth from side to side.

When using the soap bubble generator of this invention with such a structure,
Hold the main body 1 in your hand, put the air inlet 5 in your mouth, and blow into the air pipe 2.

A part of the air blown into the air pipe 2 flows to the discharge port 3 at the tip, from which soap bubbles a are fired, and the remaining air flows to the branch pipe 17 and rotates the windmill 9, causing the windmill 9 to rotate. Combined with the wind force, the soap bubbles a are blown upward from the launch port 3.

The way the soap bubbles blow up is reminiscent of the squirting of a whale.

The principle of soap bubble generation is that when the actuator 16 slides back and forth between the upper surface of the ejection port 3 and the liquid reservoir chamber 14, the soap liquid 6 in the liquid reservoir chamber 14 moves to the upper surface of the ejection port 3 and forms a film. .

Under this condition, air is blown upward and outward from the ejection port 3, so that soap bubbles a are generated.

Incidentally, the soap liquid 6 that has flowed into the liquid reservoir chamber 14 is caused by the fact that the sealed tank 7 is under negative pressure, the surface tension of the soap liquid itself acts, and the liquid reservoir chamber 14 is annular and the horizontal direction of the upper surface is Combined with the narrow width, even if the main body 1 is slightly tilted, overflowing from the upper surface of the liquid storage chamber 14 can be well prevented, and a full state is always maintained.

When the soap liquid 6 is consumed, air flows into the closed tank 7 from the upper surface of the opening of the liquid storage chamber 14, and in exchange, the soap liquid 6 is supplied to the liquid storage chamber 14, and the soap liquid 6 is supplied to the closed tank 7. As long as you keep supplying 6, you can fire soap bubbles A forever.

Note that the shape of the actuator 16 and the driving means are not limited to the above embodiments, and various shapes can be considered.

For example, FIG. 4 shows a second embodiment of the present invention, in which the overall shape of the main body 1 is cylindrical, and a funnel-shaped recess 4 is formed in the center of the upper surface. The outer periphery is a sealed tank 7 for soap liquid 6.

A rotary shaft 19 is vertically and rotatably installed in the center of the internal cavity 27 of the main body 1, and the wind turbine 9 is fixed to the rotary shaft 19 in a horizontal position, and a small gear 20 is attached to the upper part of the shaft 19. A large gear 21 is engaged with the gear 20, a shaft 22 of the large gear 21 is rotatably erected in the internal space 27, and an actuator 16 is fixed to the upper end of the shaft 22.

The ejection port 3 of the air supply pipe 2 is located at the center of the lower part of the funnel-shaped recess 4, and the actuator 16 slides between the upper surface of the ejection port 3 and the upper surface of the opening of the liquid reservoir chamber 14 on the outer periphery of the ejection port 3. It has become.

In other words, in this case as well, a part of the air blown into the air pipe 2 from the air inlet 5 flows into the branch pipe 17, and as the windmill 9 rotates, the slider 16 rotates at a reduced speed, and the actuator 16 rotates at a reduced speed. A film of soap liquid 6 is formed on the upper surface of the ejection port 3 with each rotation, so that the soap bubbles a can be ejected upward.

In addition, the present invention allows for design changes such as blowing air into the ejection port 3 and driving the actuator 16 using an electric motor.

Further, the means for supplying the soap liquid 6 to the liquid storage chamber 14 can also be freely changed.

According to the soap bubble generator of the present invention as described above, the soap bubbles a can be generated by simply blowing air into the ejection port 3 using an appropriate means, without having to immerse the ejection port 3 in the soap liquid 6 one by one. You can build it and blow it away.

At this time, the upper surfaces of the ejection port 3 and an annular liquid reservoir 14 surrounding the outer periphery thereof are opened upward, and a thin rod-shaped actuator 16 is connected to the air supply pipe on the upper surface of each of the ejection port 3 and the liquid storage chamber 14. 2
Since it slides in conjunction with the air supply action, it is possible to continuously fire soap bubbles upward as long as the air supply action continues, which makes it more interesting than when the soap bubbles are shot sideways intermittently. , it's fun to play.

Moreover, since the liquid storage chamber 14 is located below the closed tank 7 and both 4 and 7 are connected through the supply pipe 15, although the structure is simple, as long as there is soap liquid 6 in the closed tank 7, the soap will not flow. The liquid 6 is automatically supplied to the liquid storage chamber 14 in an amount corresponding to the reduced amount, and the soap bubbles a can be continued to be fired for a long time.

In addition, as long as the airtight tank 7 is sealed, the airtight tank 7 is under negative pressure, so the surface tension of the soap liquid itself acts effectively, and the width at the upper surface of the annular liquid storage chamber 14 is reduced all around. By setting the width to be uniformly narrow in all directions, even if the main body 1 is slightly tilted during use,
The soap liquid 6 does not overflow from the liquid storage chamber 14,
Easy to use for children.

Moreover, after setting the arrangement relationship between the sealed tank 7 and the liquid storage chamber 14 as described above, the soap liquid 6 is supplied to the sealed tank 7 with the main body 1 turned upside down. The soap liquid 6 does not directly flow into the liquid reservoir chamber 14 from the sealed tank 7 communicating with the atmosphere when replenishing the soap liquid.
The soap liquid 6 will not overflow.
