  FIG. 1 shows an example of a water play toy equipped with a power generation device according to the present invention. A water play toy (hereinafter referred to as a water play toy) equipped with this power generation device has a toy body 1 in a liquid (for example, hot water in a bath). A power generation device A and an operation device A that operates by the power generation of the power generation device A are disposed inside.

  The toy body 1 is composed of an upper case 1a and a lower case 1b, and the upper case 1a and the lower case 1b are partitioned by a partition plate 2 so that an upper space 3 and a lower space 4 are formed.

  The opening surface of the upper case 1a is shielded by the partition plate 2, shielded by an appropriate means such as an adhesive, and the upper space 3 forms a sealed space. In this sealed space, a melody IC 10 and a speaker (piezoelectric speaker) 11 constituting the operation device A are arranged, and a circuit board 12 on which the melody IC is mounted is fixed to the upper surface of the partition plate 2, and the speaker 11. The upper case 1a is fixed to the inner surface of the top plate of the upper case 1a so that it functions as a resonance plate.

  The lower case 1b has a large number of through holes 13 formed on the peripheral surface and the bottom surface thereof, so that liquid can enter and leave the lower space 4 formed by the partition plate 2 and the lower case 1b. A power generation device B is disposed in the.

  The power generation device B is composed of two types of electrode plates with different ionization tendencies. When the two types of electrode plates are immersed in a liquid in which hydrogen ions are present (a liquid that is not pure water and is called electrolyzed water), and is connected by a conducting wire, it is negative. Electrons move from the electrode on the side (metal with a high ionization tendency) to the electrode on the positive side (metal with a low ionization tendency), so that the current flows from the positive electrode to the negative electrode to generate electricity. It is comprised with the electric power generating apparatus based on a well-known theory. For the electrode plate corresponding to the negative electrode, a metal plate such as magnesium, aluminum or zinc having a high ionization tendency is used for the electrode corresponding to the negative electrode, and for the electrode plate corresponding to the positive electrode, a metal such as gold, platinum, silver or copper having a low ionization tendency. In the present invention, two types of electrode plates are constituted by a plurality of copper plates 14 and a single zinc plate 15, and are stacked up and down via an insulating material 16 as shown in FIG. The copper plate 14 constitutes a positive electrode plate, and the zinc plate 15 constitutes a negative electrode plate. In this embodiment, the surface area is increased by using a plurality of copper plates 14 to improve the amount of power generation.

  FIG. 4 is a block diagram showing an electrical configuration of the water play toy. In FIG. 4, reference numeral 10 denotes a melody IC constituting the operation device A, and reference numeral 11 denotes a speaker.

  The symbol B indicates a power generation device. The power generation device B is composed of two types of electrode plates (copper plate 14 and zinc plate 15) having different ionization tendencies as described above, and three sheets constituting a positive electrode plate. The copper plates 14 are connected to each other by lead wires 17, and the end portions of the lead wires 17 are connected to the melody IC 10 on the circuit board 12 through the through holes 18 formed in the partition plate 2, and the negative electrode plate is connected. Lead wires 19 connected to the constituent zinc plate 15 are connected to the melody IC 10 on the circuit board 12 through through holes 18 formed in the partition plate 2.

  As shown in FIG. 5, when the user floats the toy body 1 on the bathtub when bathing, the hot water flows into the lower space 4 from the through-hole 13 formed in the lower case 1b, as shown in FIG. The space 4 is filled with hot water, and the copper plate 14 and the zinc plate 15 are immersed in hot water. Since the hot water is not pure water, it functions as electrolyzed water, a voltage is generated between the copper plate 14 and the zinc plate 15, the melody IC 10 is activated, and the melody is output from the speaker 11.

  As described above, the melody is output simply by immersing the toy body 1 in hot water, so it can be used without worrying about whether the battery is exhausted, and when you want to play, you can use it. A water play toy that can be enjoyed at any time can be provided.

  In the water play toy described above, the toy main body 1 is formed in a disc shape, but this shape is not limited to the disc shape, and may be a sphere as shown in FIG. In this water play toy, the upper ends of the copper plate 14 and the zinc plate 15 arranged in the lower space 4 of the toy body 1 are supported by the insulator 20 and are arranged in parallel vertically, and are fixed to the bottom of the lower space 4. It is only necessary that the upper portion of the toy main body 1 protrudes from the water surface with the weight member 21.

  FIG. 7 shows another example of a water play toy. This water play toy is configured by arranging a figurative 25 imitating a flower on the top of a toy main body 1 that is formed to imitate a flower pot. The operation device A and the power generation device B described above are accommodated therein, and the tips of the lead wires 17 and 19 inserted through the inside of the support column 25 imitating a stem are arranged in a figure 25 imitating a flower. 11 is connected.

  When the water play toy is sprinkled with water from above the main body, the splashed water enters and stays in the toy main body 1 from the through hole 27 formed on the upper surface of the toy main body 11, and the copper plate 14 as the power generation device B and zinc Since the plate 15 is immersed in water until the water flows out from the lower drainage port 28, power generation is performed, and a melody is output from the speaker 11, but when the water flows out from the drainage port 28, the power generation stops, The melody output stops, you can enjoy the melody output with hot water when bathing in the bathroom, and enjoy not only the bathroom decorations you enjoy visually, but also in the auditory aspect It is possible to realize bathroom goods that can be used.
