Abstract

PROBLEM TO BE SOLVED: To provide a soap bubble device requiring less demand without causing soap liquid to be spilled. SOLUTION: A soap bubble device 10 shoots soap bubbles by blowing air from a feed port 51 to liquid film holes 21 spaced from one another on a holed plate 20. A disc 20 is formed as a disc 20A having flat faces and a uniform thickness and part of the disc 20A is put into a slit 31 provided in a liquid container 30 for rotation. Gaps Q1, Q2 between the slit 31 and the disc 20A are such that the soap bubbles are prevented from being spilled out of the gaps when the whole device is oscillated. A width between the slit 31 and the disc 20A opposed to each other at the gaps Q1, Q2 is greater than that of the size of the liquid film holes 21. The disc 20A is rotated with no friction resistance because of the gaps Q1, Q2, reducing the demand of a motor 70 for driving the device. A sector plate is used instead of the disc for oscillation without putting the cutout of the sector plate into the slit 31.

Description

DETAILED DESCRIPTION OF THE INVENTION

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a soap bubble device in which soap liquid does not spill even when the device is shaken by carrying the device.

[0002]

2. Description of the Related Art As a general structure of a soap bubble device, a structure of a soap bubble device 100 as shown in FIG.
(Referred to as prior art) is disclosed in Japanese Utility Model Publication No. 46-16568. In the following drawings, portions indicated by the same reference numerals are portions having the same functions as the portions denoted by the same reference numerals described in any of the drawings.

[0003] In FIG. 10 [overall configuration / longitudinal section]
The lower portion of the hole plate 20 is inserted into the liquid container 30 containing the soap liquid 10 from the upper opening 30P, and the hole plate 20 is rotated at a relatively low speed by the electric motor 70.

In the hole plate 20, as shown in [Main Configuration / Front] of FIG. 10, they are arranged on a circumference having a predetermined radius, that is, on the arrangement circle C1 at appropriate constant or irregular intervals. In the present invention, a liquid film hole 21 which is disposed at intervals is provided, and when the liquid film hole 21 passes through the soap liquid 10 and exits from the soap liquid 10, the viscosity of the soap liquid 10 is increased. The liquid film 21 </ b> A of the soap liquid 10 is stuck to the liquid film hole 21 by the pressure and the surface tension.

On the other hand, the impeller 52 of the blower 50 is
0 rotates at a relatively high speed, and blows air from the air supply port 51 toward the liquid film hole 21. Therefore, when the liquid film hole 21 is positioned in front of the air supply port 51, the liquid film 21 </ b> A
Is blown off while being inflated by the air blown from the air supply port 51, and the soap bubble is ejected.

Here, around the liquid film hole 21, the liquid film hole 2 is formed.
Unless a thin contour portion 21B or a ridge-like portion along 1 is provided, the liquid film 21A spreads along the surface of the hole plate 20 on the side opposite to the air supply port 51, and thus the liquid film 21A
However, there is an inconvenience that only the diameter increases while the circumference of the hole remains attached to the hole plate 20 and the soap bubble cannot be completely formed.

Further, a configuration of a soap bubble device 100 (hereinafter referred to as a second prior art) as shown in FIG. 11 provided with a liquid container 30 for preventing the soap liquid 10 from spilling is disclosed in Japanese Utility Model Registration No. 2521887. Have been.

In FIG. 11 [overall construction / perspective], the liquid container 30 is closed by a rubber lid 30D so as to prevent the soap liquid 10 from spilling out and to allow the hole plate 20 to enter and exit. A slit 31 is provided.

The hole plate 20 is provided at the tip end of the arm plate 25, and the arm plate 25 and the hole plate 20 are connected to each other in FIG.
As shown by the dotted line in the front, the liquid film hole 21 is introduced into the liquid container 30 through the slit 31 by oscillating in the form of a pendulum and immersed in the soap liquid 10, and then the liquid film hole 21 Is positioned so as to inject soap bubbles.

The liquid film hole 21 is connected to one large liquid film hole 21a.
The two small liquid film holes 21b are arranged adjacent to each other, and the air supply port 51 is aligned with the liquid film holes 21a and 21b.
By providing three air inlets, as shown in [composite soap bubble / front] in FIG. 11, a composite soap bubble 81 integrally formed with three soap bubbles can be injected, and the lower part of the front side of the liquid container 30 can be injected. In addition, an air supply port 82 for blowing off the soap bubble in a direction different from the injection direction is provided.

In the case of the second prior art, similarly to the case of the first prior art, a thin contour portion 21B is provided around the liquid film hole 21 along the liquid film hole 21. It is easy to form soap bubbles.

[0012]

In the structure of the above-mentioned second prior art, the structure is such that the soap liquid 10 does not spill out. However, the arm plate 25 and the hole plate 20 are swung upward to form the slit 31. While it is outside, the slit 31 is completely closed, and the arm plate 25 and the hole plate 20 swing down,
When entering the slit 31, the closed slit 31
Must be forcibly pushed into
Not only does the mechanism for swinging the arm plate 25 and the hole plate 20 become complicated, but the power consumption of the electric motor (not shown) is large to cover the mechanical loss of such a complicated mechanism. Therefore, a first problem is that a battery (not shown) for supplying electric power to the electric motor must be a large battery, and the life of the battery is shortened.

In both the first prior art and the second prior art, the liquid film hole 2 is provided around the liquid film hole 21.
Since it is difficult to form a soap bubble unless the narrow contour portion 21B or the jetty portion along the line 1 is provided, in order to prevent the soap liquid 10 from being spilled by the slit 31 as in the second prior art, the arm plate 25 and the hole plate are required. There is a second problem that it is necessary to make the structure in which the 20 enters and exits the slit 31.

[0014]

According to the present invention, the hole plate 20 is constituted by a disk having liquid film holes 21 disposed therein, and the disk is rotated in a slit 31 so that the disk and the slit 31 are rotated.
Is set to such a small value that the soap liquid 10 does not spill out of the gap when the whole apparatus is shaken, and the disc, the slit 31 and the disc at the location of this gap face each other. The first problem is solved by setting the width to be wider than the size of the liquid film hole 21.

Also, the direction of blowing air from the air supply port 51 is inclined with respect to the surface of the disk to facilitate the formation of soap bubbles, thereby eliminating the need for the thin contour portion 21B or the jetty portion. It is a simple disk or fan-shaped plate that solves the second problem.

[0016]

The circular hole plate 20 occupies a certain thickness in the slit 31 and continuously rotates in a certain direction. Therefore, a slight gap is formed between the hole plate 20 and the slit 31. Is provided, it is possible to prolong the life of the battery by driving the rotation of the hole plate by a simple mechanism having a small resistance without causing leakage of the soap solution. As a result, it is possible to play soap bubbles for a long time even with a small capacity battery.

Since the direction in which the air is blown from the air supply port 51 is inclined with respect to the surface of the disk or the sector plate, one side of the liquid film 21A is separated from the surface of the disk or the sector plate. Since it is inflated in shape, it is easy to form as a soap bubble.

[0018]

FIG. 9 is drawn in almost the same size as the actual actual product, that is, almost in full size.

[0019]

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS [First Embodiment] A first embodiment will now be described with reference to FIGS.
An embodiment will be described. This embodiment is an embodiment in which a hole plate 20 made of a circular plate is used. In FIGS.
The electric motor 70 includes an impeller 52 fixed to a rotating shaft 71 of the electric motor 70, a gear 61 provided on the impeller 52, a gear 62 meshing with the gear 61, and a worm 6 provided on a shaft 62 </ b> A of the gear 62.

3 is 2 mm, and the spline shaft portion 69
The outer diameter D2 of the circular portion is 4 mm, the width B2 of the overhang portion 69a is 2 mm, and the outer diameter D3 of the overhang portion 69a is 8 mm. The disk 20A is made of a synthetic resin material such as an ABS resin having a constant thickness t1 and capable of withstanding bending, having both flat and smooth surfaces.

Further, the shape of the spline hole 69A is larger by about 3 to 5% than the outer shape of the cross section of the spline shaft portion 69, that is, the outer shape of the [II cross section] of FIG. By making the shape larger by about 0.1 mm to 0.2 mm, the disk 20A moves in the axial direction with respect to the spline shaft portion 69, or the disk 20A
8, the inclusions 31C and 31D, which will be described later, are not concentric with the outer periphery of the disc 20A with respect to the axis of the shaft 68. In this case, the disc 20A can be rotated by the spline shaft portion 69.

The insertion of the disk 20A into the liquid container 30 and the assembling of the gear 67 with the gear 66 are performed by the disk 20A.
A in the state where A is fitted into the spline shaft portion 69, FIGS.
As shown in FIG. 3, a part of the disc 20A, that is, a part corresponding to the lower part of FIG. 1 [overall configuration / front] and FIG. 3 is inserted into the slit 31, and the gear 67 is engaged with the gear 66. In this state, the shaft 68 is protruded from the lid portion 30B of the liquid container 30.
(The whole configuration / front of FIG. 1) is inserted into the U-shaped groove 41A, so that the pressing plate 41B is screwed from above the shaft 68 into the screw 41.
When fixed with C, mounting is possible.

The liquid container 30 has a lid 3 and a main body 30A.
By fixing OB with the screw 30C, other parts except the slit 31 can be closed. In addition, lid part 3
0B is provided with a hole 36A for replenishing the soap liquid 10 and a stopper 36B for closing the hole 36A.

The positional relationship between the slit 31, the disc 20 A and the air supply port 51 can be determined by appropriately setting the blower 50 and the liquid container 30 to the pedestal 90 via the column portions 91, 92, 93 and the spacer portion 94. And by fixing it with screws,
A predetermined positional relationship is maintained, and the blowing direction W of the air from the air supply port 51 is positioned in the tangential direction of the arrangement circle C1 and is inclined at a predetermined inclination angle θ with respect to the surface of the disk 20A. It is positioned as follows. Note that the inclination angle θ and the positioning of the arrangement circle C1 in the tangential direction are as follows.
The angle varies depending on the air supply capacity of the blower 50, the rotation speed of the disk 20A, the area and shape of the liquid film hole 21, and the like.

As shown in FIG. 1 [overall configuration / plane], the slit 31 includes inclusions 31A and 31B that sandwich the both surfaces 20a and 20b of the disk 20A with a required gap Q1 therebetween.
Inclusions 31C and 31D that sandwich the outer peripheral end surface 20c of the disk 20A with a required gap Q2 (not shown) are provided.
As shown in FIG. 4 [assembled state / perspective], a slit 31 surrounded by these inclusions 31A, 31B, 31C, 31D is formed.

The gaps Q1 and Q2 are set to such a size that the soap liquid 10 does not spill out even when the whole apparatus is shaken. In order to prevent the liquid 10 from spilling out, the gap is set to such a degree that the soap liquid 10 does not leak due to the surface tension of the soap liquid 10, and the depth of each of the gaps Q1, Q2, that is, the disc 20A and the slit are formed. The width B1 of the portion facing 31 is set to be larger than the liquid film hole 21 as shown by the chain line in FIG.

More specifically, as shown in FIG. 4 [disassembled state / perspective], inclusions 31A and 31B sandwiching both surfaces 20a and 20b of the disk 20A are connected to both surfaces 20a and 2 of the disk 20A.
On the surfaces 31A1 and 31B1 on the side opposing 0b, a surface having a small frictional resistance is formed so as to smoothly and separately contact both surfaces 2a and 2b of the disk 20A,
The thickness t11 of the inclusions 31C and 31D is set to the same thickness as the thickness t1 of the disk 20A, and the arc shape of the portions 31C1 and 31D1 facing the end surface of the disk 20A is changed to the outer circumference of the disk 20A. Sliding contact is made.

A state in which the inclusions 31A, 31B, 31C, and 31D are combined as shown in FIG. 4 [assembled state / perspective] is shown in FIG. After being inserted into a slit frame hole 32 provided in the lid 30B of the liquid container 30, the liquid container 30 is fixed with an appropriate fixing member 33, as shown in FIG. The battery 71 for driving the electric motor 70 and the switch 7
2 is fixed to an appropriate position of the pedestal 90, for example, as shown by a chain line.

The thickness t2 in the state where the inclusions 31A, 31B, 31C and 31D are combined in the [main part assembled state / perspective] of FIG. 4 is the same as that in the [main part disassembled state / perspective] of FIG. The depth t3 of the slit frame hole 32 is slightly smaller than the depth t3, for example, about 0.1 mm, and the width of each of the inclusions 31A, 31B, 31C, 31D is set to the above-described opposed width B1, and further, the slit hole is formed. Similarly, when the disc 20A is inserted into the slit 31, the inclusions 31A
The space between B is opened to form a gap Q1.

The inclusions 31A and 31B are, for example, formed by coating the surface of a rubber material with a synthetic resin material having a small frictional resistance or by impregnating a paraffin material, and are products of Bridgestone Corporation. The name "Zuren" corresponds to this.

In the case of the first embodiment, the inclusion 31A
Is composed of the above-mentioned “slurry”, and the smooth surface with the formed film at the time of vulcanization molding of the sponge rubber is used as the surface 3 on the side facing the disk 20A, with the inclusion 31B as the sponge rubber.
When the disc 20A is inserted, the sponge rubber can be easily inserted by the deformation of the sponge rubber, and the follow-up and correction when the rotating surface of the disc 20A is inclined can be performed by the soft elasticity of the sponge rubber. To prevent the disc 20A from being damaged.

The inclusions 31C and 31D have a circular plate 20.
The fixing member 33 is formed of the same synthetic resin material as A, for example, an ABS resin material, and has a configuration in which a collar 33B is press-fitted and fixed to the tip side of a pin 33A made of the same material. For example, the inner portion is made of a material such as an acrylic resin material that can be seen through.

A specific example of the dimensions of each part is that the width B1 is 7.5.
mm, thickness t11 is 0.5 mm, thickness t12 is 1.1 m
m, thickness t2 is 2.7 mm, length L1 is 57 mm, and D1 + α of the arc-shaped portions of the inclusions 31C and 31D facing the disk 20A is 50.2 mm. Further, the surface of the entrance of the slit 31, that is, the width B
1 and the center of the disk 20A, that is, the axis 6
The height H1 between the shaft 8 and the position of the axis 8 is set to 5 mm.
The gap Q1 is 0.1 mm, which corresponds to the size of the gap when the disk 20A is moved to one side of the slit 31. That is, in the case of this embodiment, the gaps Q1 and Q2 are set to such a size that the soap liquid 10 does not spill out of the gaps Q1 and Q2 even when the entire apparatus is turned upside down by the surface tension of the soap liquid 10. It is.

[Second Embodiment] A second embodiment will now be described with reference to FIG. The second embodiment differs from the first embodiment in the configuration of the first embodiment in that the hole plate 20 is formed into a sector plate 20B and the sector plate 20B is rotated without rotating the sector plate 20B.
The point is that the rocking mechanism is configured so as to swing at a swing angle within a range in which B can be present in the slit 31.

In FIG. 6, a sector plate 20B is formed by cutting out a part of the circular plate 20A in the first embodiment to form a sector, and a portion for swinging the sector plate 20B (shown in FIG. 6). The configuration of (b) is the same as the configuration of the portion for swinging the hole plate 20 and the arm plate 25 in a pendulum shape in the second conventional technique.

Then, without rotating the sector plate 20B, the sector plate 20B is swung at a swing angle within a range in which the sector plate 20B is inserted into the slit 31, so that the sector plate 20B is rotated.
The gaps Q1 and Q2 are formed in the same manner as in the first embodiment by preventing the cutout portion 20x from entering the slit 31.
It is something that can be prevented from falling.

Third Embodiment A third embodiment will be described below with reference to FIG. The difference of the third embodiment from the first embodiment is that, in order to further increase the inclination angle θ, the mounting posture of the liquid container 30 is also inclined, and the gear 66 and the gear 67 Is configured to be inclined such that the meshing portion intersects in a "shape" like a cross gear mechanism. In addition, by providing an adjusting mechanism that can also adjust the mounting posture of the liquid container 30, a configuration that can ensure the best inclined state can be provided.

[Modification] The present invention includes the following modifications.

(1) The liquid film hole 21 is constituted by a plurality of holes of different sizes, for example, as shown in FIG. In FIG. 8, when the liquid film holes 21a and 21b are provided,
It is possible to inject a composite soap bubble similar to the composite soap bubble 81 in the prior art. However, in the configuration of the modified example, three soap bubbles are intermittently blown all at once as in the second conventional technology. By taking out and assembling into one lump, for example, instead of growing into a snowball-like composite soap bubble, a large number of small and large liquid film holes 21 are provided for one air supply port 51.
a.21b passes one by one with a time lag,
A plurality of soap bubbles are continuously fired and scattered, so that a soap bubble device different in taste from the second prior art can be obtained. In this case, in the case where the light is scattered, the depth of the gaps Q1 and Q2 in the [main assembly state / perspective] of FIG. Width B
As shown by a chain line in FIG. 8, by making the liquid film hole groups 21a and 21b larger than the entire outer circumference of the large and small liquid film hole groups 21a and 21b,
It is preferable that the liquid films 21A of the liquid film holes 21a and 21b are not short-circuited when passing through the facing portion of the slit 31.

(2) When the gaps Q1 and Q2 are shaken by carrying the soap bubble apparatus 100 or the like, the gap is small enough to prevent the soap liquid 10 from spilling out of the gaps Q1 and Q2, for example, 0.3. The gap is extended to about 0.8 mm, that is, about 1.5 times the thickness t1 of the disk 20A.

(3) In the above (2), the shape of the air supply port 51 is changed in the same manner as in the second prior art described above.
An air supply port is provided for each 1b or each of the liquid film holes 21a and 21b2, and the width B1 is set to be wider than the largest of the liquid film holes.

(4) The distance between the liquid film holes 21 is, for example,
As shown in FIG. 9, they are arranged at irregular intervals. (5) The configuration of the third embodiment is applied to the configuration of the second embodiment. (6) Similar to the above-described second conventional technique, an air supply port 82 for blowing off a soap bubble in a direction different from the injection direction is provided.
