  As shown in FIGS. 1 to 3, the spray toy 1 is formed to imitate the form of a tow vehicle in a steam locomotive. A motor 3 (see FIG. 10) is mounted on the toy body 2 of the spray toy 1. The spraying toy 1 travels with the wheels 4 being driven by the motor 3. The spray toy 1 can be run manually. Furthermore, the toy body 2 is provided with a speaker 5 (see FIG. 10). The speaker 5 is configured to output a pseudo steam generation sound. The toy main body 2 is provided with a fog generating unit 6 as shown in FIG. Then, particles (atomized particles) 40 atomized by the fog generating unit 6 are ejected from the chimney (ejection cylinder) 7. The ejection of the atomized particles 40 and the output of the pseudo steam generation sound are synchronized. The atomized particles 40 ejected from the chimney 7 are illuminated by light from the chimney 7. This illumination is synchronized with the ejection of the atomized particles 40. The spray toy 1 is provided with a battery 30 and switches 21, 22, and 23 as shown in FIG. Hereinafter, details of the spray toy 1 will be described.

  First, the mist generating unit 6 will be described. As shown in FIGS. 4 to 6, the mist generating unit 6 includes a base frame 9 to which a liquid retaining material 8 is attached and which can be attached to the toy main body 2, and electrodes on both end surfaces. An ultrasonic wave generating element 12 constituted by fixing the vibration plate 11 to one end face of the piezoelectric vibrator 10, which is 10 a and 10 b, is attached and operates with respect to the base frame 9 to keep the vibration portion 11 a of the vibration plate 11. And a movable member 13 to be brought into contact with the liquid material 8.

Among these, the piezoelectric vibrator 10 includes a rectangular piezoelectric ceramic 10c as shown in FIG. The piezoelectric vibrator 10 has a structure in which Au electrodes 10a and 10b are formed on both end faces of the piezoelectric ceramic 10c, and terminals 10d and 10e are attached to the Au electrodes 10a and 10b. The diaphragm 11 is attached so as to partially overlap one end face of the piezoelectric vibrator 10. A portion of the vibration plate 11 that protrudes from the piezoelectric vibrator 10 constitutes a vibration portion 11a. As shown in FIG. 9, the vibrating portion 11a has many fine holes 11b penetrating in the thickness direction. The hole 11b has a shape that narrows toward the ejection side of the atomized particles 40.
For example, a sponge is used as the liquid retaining material 8.

  The base frame 9 is attached to the toy main body 2 with screws (not shown) that pass through the through holes 9a. The liquid retaining material 8 is attached to the base frame 9 by fitting from below (from the side opposite to the movable member 13) in FIG. A part of the liquid retaining material 8 is led out to the upper side of the base frame 9. In this case, it is not always necessary to attach the entire liquid retaining material 8 to be used to the base frame 9, and the liquid retaining material 8 to be attached to the base frame 9 may be the minimum necessary. For example, only the liquid retaining material 8 corresponding to the portion in contact with the vibration part 11 a may be attached to the base frame 9. In this case, since it cannot be denied that the amount of liquid retention decreases, it is preferable to separately provide the liquid retention material 8 on the lower side. Moreover, replenishment of water or the like to the liquid retaining material 8 is performed using, for example, a dropper. Although supply of water etc. with a dropper is not specifically limited, it is performed through the hole for insertion of a dropper provided in the toy main body 2. In the case where a liquid retaining material is provided separately from the liquid retaining material 8 corresponding to the portion in contact with the vibration part 11a, the liquid retaining material container for housing the latter liquid retaining material can be attached to and detached from the toy body 2. After the liquid retaining material is moistened with water or the like, it may be attached from the lower side of the toy main body 2 so as to contact the liquid retaining material 8 to replenish water or the like. Alternatively, a tank for storing water or the like for wetting the liquid retaining material 8 corresponding to the portion in contact with the vibrating portion 11a may be provided. However, when this tank is provided, care should be taken because liquid leakage may occur when the spray toy 1 is tilted.

  On the other hand, the movable member 13 is attached to the base frame 9 via a hinge 14. That is, the movable member 13 is attached to the base frame 9 so as to be rotatable about the shaft 14a. An ultrasonic wave generating element 12 is attached to the distal end side of the movable member 13. In other words, the housing recess 13 a of the rectangular piezoelectric vibrator 10 whose upper and distal ends are open is provided at the distal end of the movable member 13. The lower portion of the piezoelectric vibrator 10 is fitted into the housing recess 13a. In this case, if the entire surface of the piezoelectric vibrator 10 comes into contact with the bottom surface of the housing recess 13a, there is a risk that the piezoelectric vibrator 10 will not vibrate. Therefore, a plurality of contact portions 13b that contact only a part of the peripheral portion of the one surface of the piezoelectric vibrator 10 are provided on the bottom surface of the housing recess 13a. Further, a lid body 13c is provided at the tip of the movable member 13 so as to cover the housing recess 13a from above. The lid 13c is also provided with an abutting portion 13d that contacts only a part of the peripheral portion on the other surface side of the piezoelectric vibrator 10. Then, the lid 13c is attached to the movable member 13 by screwing a screw (not shown) through the through hole 13e into the screw hole 13f of the movable member main body.

  As shown in FIGS. 5 to 7, the vibrating portion 11 a of the diaphragm 11 protrudes from the tip of the movable member 13 when the ultrasonic wave generating element 12 is attached to the movable member 13. When the movable member 13 is closed with respect to the base frame 9, the vibrating portion 11 a is brought into contact with the liquid retaining material 8. In this case, the movable member 13 may be configured to automatically close with respect to the base frame 9 by gravity acting on the movable member 13. Further, a spring may be attached between the movable member 13 and the base frame 9 so that the movable member 13 is urged in a closing direction with respect to the base frame 9 by a spring force.

  The fog generating unit 6 configured as described above is installed in a place where the droplets resulting from the adhesion of the atomized particles 40 do not fall on the vibration part 11a. For example, as shown in FIG. 2, when considering a silhouette in which the introduction port of the atomized particles 40 of the chimney 7 erected on the toy main body 2 is projected directly below, the diaphragm 11 is located at a location outside the silhouette. Thus, the fog generating unit 6 is installed. On the other hand, the fog generating unit 6 is installed so that the atomized particles 40 generated by the vibration part 11a can be effectively guided to the introduction port of the chimney 7. For example, as shown in FIG. 2, the mist generation unit 6 is installed so that the diaphragm 11 can be directed to the atomizing particle 40 from obliquely below with respect to the inlet of the chimney 7.

  The toy body 2 is provided with illumination means 16 that illuminates the atomized particles 40. The illuminating means 16 illuminates the sprayed atomized particles 40 from the chimney 7. The illumination means 16 is not particularly limited, but a light emitting diode 16a is used. The light-emitting diode 16a has a transparent waterproof cover so that liquid droplets do not fall from the chimney 7 when the silhouette of the chimney 7 in which the atomized particle 40 inlet is projected is considered. Is covered. In the case of this embodiment, since it is a tow vehicle in a steam locomotive, a red light emitting diode is used as the light emitting diode 16a. In the case of a red light emitting diode, the inside of the chimney 7 and the lower side of the atomized particles 40 to be ejected are colored red, so that an image as if the internal combustion engine is operating in the toy body 2 is created. The light emitting diode itself may not be red, but a red filter, a red transparent cover, or a red mirror may be used. Of course, you may make it illuminate the inside of the chimney 7 and the atomized particle 40 ejected by another color. In this case, a fantastic image is created. In addition, a light bulb can be used instead of the light emitting diode 16a.

FIG. 10 shows an example of a circuit applied to the spray toy 1 of the above embodiment.
In the figure, reference numeral 20 denotes a control IC, and 21, 22, and 23 denote switches.

  A switch 21 indicates a mode switch. The mode changeover switch 21 is provided on the toy main body 2 and is artificially operated. The switch 21 can take three positions from position 1 to position 3 as shown in FIG. At position 1, both the motor 3 and the self-excited circuit 21 are operable. At position 2, the motor 3 becomes inoperable and the self-excited circuit 21 becomes operable. The case where the position 2 is taken is a case where the spray toy 1 is manually driven. At position 3, both the motor 3 and the self-excited circuit 21 are inoperable. That is, the position 3 is taken when the power is turned off.

  The switch 22 is operated in accordance with the rotation of the wheel 4 of the spray toy 1. The switch 22 is operated by, for example, a cam provided on the rotating shaft of the wheel 4 or a cam provided integrally with the wheel 4. This switch 22 is turned on every rotation of the wheel 4. When this switch 22 is turned on, the self-excited excitation circuit 24 is driven by the control IC 20, and the diaphragm 11 of the ultrasonic wave generation element 12 vibrates to generate atomized particles 40. In conjunction with this, the control IC 20 turns on the light emitting diode 16 a as the illumination means 16, and the steam generation sound is output from the speaker 5. The switch 23 is turned on manually. When this switch 23 is turned on, sound other than steam generation sound is output from the speaker 5. The switch 23 is turned on temporarily. That is, the button for turning on the switch 23 is automatically returned when the button is pressed and released.

  Of these, the self-excited excitation circuit 24 will be described. The self-excited excitation circuit 24 is a self-excited excitation circuit having a current feedback transformer. By adopting this self-excited excitation circuit, an adjustment element such as a tuning circuit becomes unnecessary, and a drive circuit that combines oscillation and drive can be simply configured. The self-excited excitation circuit 24 is driven when a driving transistor (for example, an NPN transistor) 25 is turned on. The driving IC 25 is turned on when the switch 22 is turned on. In this case, each time the switch 22 is turned on, the driving transistor 25 may be driven by the control IC 20 for a predetermined time. However, every time the switch 22 is turned on by the predetermined number, the control IC 20 The driving transistor 25 may be driven for a predetermined time. When the switch 22 is turned on and the switch 23 is turned on at the same time or close to each other, for example, the audio output based on the switch 23 is given priority. In this case, the light emitting diode 16a is not turned on by the control IC 20.

  Explaining the overall operation of the circuit configured as described above, when the switch 21 for mode switching takes the position 1, the motor 3 is driven and the spray toy 1 automatically runs. At that time, the driving transistor 25 is turned on with the rotation of the wheel 4, whereby the ultrasonic wave generating element 12 is driven and the atomized particles 40 are generated. At that time, a pseudo steam generation sound is output from the speaker 5 based on the sound data stored in the control IC 20, and the light emitting diode 16a is turned on.

  In addition, when the mode switching switch 21 takes the position 2, when the spray toy 1 is manually driven, the driving transistor 25 is turned on as the wheel 4 is rotated, and thereby the ultrasonic generating element 12 is turned on. Is driven to generate atomized particles 40. At that time, a pseudo steam generation sound is output from the speaker 5 based on the sound data stored in the control IC 20, and the light emitting diode 16a is turned on.

  When the switch 23 is turned on at the position 1 and the position 2, the user talks for a predetermined time. For example, a voice such as “I, locomotive XX” or “currently passing XX” is output. When this switch 23 is turned on, the talk is given priority over the pseudo steam generation sound.

  As mentioned above, although embodiment of this invention was described, it cannot be overemphasized that this invention is not limited to this embodiment, A various deformation | transformation is possible in the range which does not deviate from the summary.

  For example, a core can be put in the ejection cylinder and the atomized particles 40 can be ejected in a ring shape. In the case of the embodiment, a guide plate that guides the atomized particles 40 to the lower side of the vehicle body may be provided to eject the atomized particles 40 from the lower side of the vehicle body. Furthermore, it is possible to intermittently eject the atomized particles 40 by providing a smoke reservoir and extruding it with a piston or the like.

  Moreover, although the case where it applied to the tow vehicle of a steam locomotive was described in the said embodiment, it can apply also to a car toy and other toys. For example, in the case of a car toy, a tractor toy or a ship toy, the atomized particles 40 can be made to resemble the real thing by discharging them from the exhaust pipe. Further, in the case of a fountain toy, the image of an actual fountain is created by ejecting atomized particles from an ejection cylinder resembling a nozzle.

  Furthermore, in the above embodiment, the ultrasonic wave generating element 12 has a structure in which the vibration plate 11 is fixed to one end face of the piezoelectric vibrator 10, but the vibration plate is sandwiched between the two piezoelectric vibrators. It may have a structure in which the outer surface of the two piezoelectric vibrators (surface opposite to the sandwiching surface) is used as an electrode. .
