Water submergence toy

Abstract

A water submergence toy using screws requires two electric motors to move straight ahead and turn. Because of this, it is difficult to reduce the size of the water submergence toy. Further, when moving straight ahead, the two electric motors must operate at the same time thereby increasing the amount of battery power consumed resulting in shorter operating times the toy can be continuously used. The water submergence toy related to the present invention drives a pump using one electric motor and uses a directional control valve to change the direction liquid expelled from this pump is directed. As an example, if the liquid is discharged towards the rear, the water submergence toy can move forward and if the liquid is discharged from the lateral part of the rear, the water submergence toy can turn. In addition, the switching action of this directional control valve is performed by means of reversing the rotational direction of the electric motor thereby eliminating the need for an actuator such as a separate electric motor.

1 . A water submergence toy provided with a centrifugal type pump that is rotated and driven by means of an electric motor and moved by means of sucking in peripheral fluid using said pump and discharging the fluid from a discharge port in a desired direction, with said water submergence toy being characterized by having a divergence path that diverts a discharge path of a pump to each discharge port provided at two locations along with being provided with a directional control valve that guides fluid discharged from a pump to either divergence path at a branch portion of this divergence path and drive said directional control valve by changing the direction of rotation of said electric motor and guide the fluid to the other divergence path.  
   
   
       2 . A water submergence toy as set forth in  claim 1  wherein a driven gear is mounted to the axis of rotation of said pump and a idle gear provided that always meshes with this driven gear along with a drive gear mounted to the axis of rotation of said electric motor and a planet gear that always meshes with this drive gear to allow the outer periphery of the drive gear to move and the direction of rotation of said electric motor is reversed forward and backward to achieve selective meshing of said planet gear with either said driven gear or said idle gear and said directional control valve being driven together with the movement of said planet gear.  
   
   
       3 . A water submergence toy as set forth in  claim 1 , wherein an intake port of said pump is opened towards the downward direction.  
   
   
       4 . A water submergence toy as set forth in  claim 1 , wherein the other discharge port faces towards the rear and fin members are provided on both sides of a main body to generate a diving force downward by the toy moving forward.  
   
   
       5 . A water submergence toy as set forth in  claim 1 , wherein said divergence path branches in two directions to guide fluid in two directions at the same time.  
   
   
       6 . A water submergence toy characterized by being provided with two power units whose principal components are the above-mentioned pump, electric motor, directional control valve, and various gears forming a composition wherein each fluid is suitably discharged from a nozzle that opens in four directions.
