  Hereinafter, this embodiment will be described. In addition, this embodiment demonstrated below does not unduly limit the content of this invention described in the claim. In addition, all the configurations described in the present embodiment are not necessarily essential configuration requirements of the present invention.

1. Configuration of Video Display Device with Thin Water Tank FIG. 1 is a diagram showing an example of an external perspective view of a video display device with a thin water tank to which the bubble regulator of the present embodiment is applied.

  The video display device 1 with a thin water tank includes a video display device 2, a thin water tank 3 that is attached to the front surface of the display unit 2 a of the video display device 2, and stores liquid. A bubble generator 20 that generates bubbles therein, an air supply pipe 4 connected to the bubble generator 20, and an air pump 5 that supplies air to the air supply pipe 4 are provided. The image display device 2 generates an image of aquatic organisms (seawater fish, freshwater fish, aquatic plants, etc.), and displays the generated image on the display unit 2a (display). In this embodiment, a porous air stone that generates fine bubbles is used as the bubble generator 20, but a tube having a plurality of small holes in the longitudinal direction is used as the bubble generator 20. May be.

  The video display device 1 with a thin water tank of the present embodiment further includes a bubble regulator 10. The bubble adjuster 10 is disposed at the bottom of the thin water tank 3 and adjusts the size of bubbles generated from the bubble generator 20. A bubble BB whose size is adjusted by the bubble adjuster 10 is generated in the liquid of the thin water tank 3.

2. Configuration of Bubble Adjuster FIGS. 2A to 2C show an example of the configuration of the bubble adjuster 10. 2A to 2C are a top view, a front view, and a side view of the bubble generator 10, respectively.

  The bubble regulator 10 includes a plurality (20 in the example shown in FIG. 2) of bubble reservoirs 12 on the upper surface thereof. The bubble retaining portion 12 has an upwardly convex dome shape, and accumulates bubbles generated from the bubble generator 20 inside (hollow portion). The bubble generator 20 is disposed inside the bubble adjuster 10 (an internal space defined by the upper surface, the side surface, and the bottom surface of the bubble adjuster 10).

  The bubble reservoir 12 is provided with one air discharge hole 14 (hole) on the dome-shaped wall surface. The bubbles (air) accumulated in the bubble reservoir 12 are discharged from the air discharge hole 14 into the liquid in the thin water tank 3. Here, the air discharge hole 14 is provided at a position displaced from the dome apex of the bubble reservoir 12. Accordingly, the bubbles generated from the bubble generator 20 are not discharged from the air discharge holes 14 as they are, but are temporarily stored inside the bubble reservoir 12. In the example shown in FIGS. 2A to 2C, the air discharge hole 14 is provided at a position shifted from the apex of the dome in a direction perpendicular to the longitudinal direction of the bubble regulator 10.

  3A to 3C are longitudinal sectional views of the bubble regulator 10. As shown in FIG. 3A, the fine bubbles MB generated from the bubble generator 20 are accumulated near the top of the dome of the bubble reservoir 12 located above to form a larger bubble BB. When the bubble BB accumulated in the bubble reservoir 12 becomes large until it reaches the air discharge hole 14, the accumulated bubble BB is discharged from the air discharge hole 14 at once (see FIG. 3B), and this is repeated thereafter. .

  Therefore, according to the bubble regulator 10 of the present embodiment, relatively large bubbles can be repeatedly generated at intervals, and the monotonous fine bubbles generated from the bubble generator 20 are adjusted to improve the appearance. , Bubbles suitable for ornamental purposes can be generated in the liquid.

  In the bubble regulator 10 of the present embodiment, the size and generation period of bubbles generated from the air discharge holes 14 can be changed depending on the position of the air discharge holes 14 provided in the bubble reservoir 12.

  For example, in the bubble reservoir 12 shown in FIG. 3 (C), the air discharge hole 14 is provided at a position closer to the dome apex than the bubble reservoir 12 shown in FIGS. 3 (A) and 3 (B). Yes. Accordingly, in the case shown in FIG. 3C, the bubbles BB accumulated in the bubble reservoir 12 are smaller than in the cases shown in FIGS. The bubble BB is small, and the generation cycle of the bubble BB generated from the air discharge hole 14 is shortened. That is, the closer the position of the air discharge hole 14 provided in the bubble reservoir 12 is to the top of the dome, the smaller the generated bubbles and the shorter the bubble generation cycle, and the position of the air discharge hole 14 provided in the bubble reservoir 12 is The farther from the top of the dome, the larger the generated bubbles and the longer the generation cycle of the bubbles.

  In the bubble regulator 10 of the present embodiment, the air discharge holes 14 are provided at positions different from the other bubble reservoirs 12 in at least one of the plurality of bubble reservoirs 12. In this way, bubbles of different sizes can be generated from the plurality of bubble reservoirs 12 at different generation cycles, and bubbles that are rich in change and suitable for viewing can be generated in the liquid.

  Further, by rotating (or tilting) the bubble regulator 10 or the bubble reservoir 12, the position of the air discharge hole 14 is changed, whereby the size and generation period of bubbles generated from the air discharge hole 14 can be varied. You may make it do.

  For example, in the example shown in FIGS. 4A and 4B, the size of the bubble generated from the air discharge hole 14 by rotating the entire bubble adjuster 10 about the axis along the longitudinal direction of the bubble adjuster 10. And the generation cycle is changed. That is, in the state after rotation shown in FIG. 4B, the air discharge hole 14 moves upward as compared to the state before rotation shown in FIG. Therefore, in the state after rotation shown in FIG. 4B, the bubbles BB accumulated in the bubble reservoir 12 are smaller than in the state before rotation shown in FIG. The bubble BB (to be discharged) is small, and the generation cycle of the bubble BB generated from the air discharge hole 14 is shortened.

  Instead of rotating the bubble regulator 10 as a whole, the bubble reservoir 12 may be configured independently of the other parts, and only the bubble reservoir 12 may be rotated. Further, the bubble regulator 10 or the bubble reservoir 12 may be configured to be manually rotated, or may be configured to be rotated using a drive mechanism such as a motor.

  In this way, by configuring the bubble regulator 10 and the bubble reservoir 12 to be rotatable, the size of bubbles generated from the air discharge holes 14 by the viewer arbitrarily or in accordance with the image displayed on the image display device 1. And the generation cycle can be changed.

3. Modifications The present invention is not limited to that described in the above embodiment, and various modifications can be made. For example, terms cited as broad or synonymous terms in the description in the specification or drawings can be replaced with broad or synonymous terms in other descriptions in the specification or drawings.

  For example, in the present embodiment, the case has been described in which the bubble reservoir 12 has an upwardly convex dome shape. However, any shape can be used as long as the shape is an upwardly convex shape and the bottom is open and has a hollow portion. But you can. For example, as shown in the cross-sectional view of FIG. 5A, the bubble reservoir 12 may have a convex conical or pyramidal shape, and air discharge holes 14 may be provided on the side surfaces of the conical or pyramidal shape. As shown in the cross-sectional view of FIG. 5 (B), the bubble reservoir portion 12 may be formed as an upwardly convex cylinder or prismatic shape, and air discharge holes 14 may be provided on the side surface of the cylinder or prismatic shape.

  Further, in the present embodiment, the case where the bubble regulator 10 is configured by arranging a plurality of bubble reservoirs 12 in a row has been described. However, as shown in the top view of FIG. You may make it comprise the bubble regulator 10 side by side.

  In the present embodiment, the case where one air discharge hole 14 is provided in one bubble reservoir 12 has been described. However, a plurality of air discharge holes 14 are provided at the same height in one bubble reservoir 12. It may be.
