In addition, the water discharge passage 24 may be formed to have the same shape and size in the form of left and right symmetry, but the water discharged through the water discharge passage of any one side in the form of approximately left and right symmetry. It is possible to form different shapes and sizes of the water discharge passage 24 so that the driving force by the greater than the driving force by the water discharged through the water discharge passage on the other side. For example, if the driving force by the water discharged through the water discharge passage formed on the right side is set larger than the driving force by the water discharged through the other water discharge passage, the driving force by the water discharged through the water discharge passage. If the board body 10 is not subjected to any other force, the board body 10 can be returned to the initial position by drawing a large circle in the counterclockwise direction.

In addition, the water discharge passage 24 preferably has a shape in which the size of the cross section is gradually reduced toward the rear in the pushing direction, and the water discharged from the passage 24 is left of the board body 10. It is preferable that the water discharged from the passage 24 does not directly collide with the head or the upper body of the user located behind the board body 10.

The propeller 40 is rotatably mounted to the water inlet passage 22, and the propeller 40 is sufficient to be a screw propeller commonly used to propel a ship. The water introduced through the water inflow passage 22 by the rotational drive is divided into the water discharge passage 24 and is discharged.

The propeller 40 is rotationally driven by a driving means, the driving means being a driving motor 50 connected to the rotating shaft 42 of the propeller 40 and a battery for supplying power to the driving motor 50 ( 52). In addition, the driving motor 50 and the battery 52 may be mounted in a groove 12 formed in the board body 10 so as to be decomposable, and the groove 12 is covered by a cover 60 so that the water is covered with water. Penetration of the groove 12 is prevented.

More preferably, a box-shaped housing 70 having an open upper portion is inserted into the groove 12 so as to be disassembled, and the driving motor 50 and the battery 52 are mounted inside the housing 70. do. In addition, a through hole 62 through which a charging plug (not shown) for charging the battery 52 is formed in a central portion of the cover 60, and a rubber stopper is formed in the through hole 62. 64 is mounted to maintain airtightness.

The method of connecting the propeller 40 and the driving motor 50 may use the belt 44 as in the embodiment of the present invention, and may be configured in various aspects such as a method of connecting to each other and a method of connecting directly through a gear. have.

In the present invention using the belt 44, the rotation shaft 42 of the propeller 40 has a configuration that is connected to the shaft of the drive motor 50 via the belt 44.

In addition, according to the present invention, the light 14 which is electrically connected to the battery 52 and emits light may be installed at an upper end of the board body 10.

In addition, the bolt gauge 16 which is electrically connected to the battery 52 to indicate the remaining amount of the battery 52 is installed on the upper portion of the board body 10, so that the charging of the battery 52 at a proper time It is good to make it happen.

And, the handle 18 should be formed on both sides of the board body 10, which is preferable in that it can be more comfortable to play in water than in the case of holding the both sides of the board body 10 directly by hand. Do.

At least one side of the handle 18 should be provided with a switch (not shown) to rotate the drive motor 50 of the drive means, and also by mounting a long strap on one side of the handle 18 It is good to make it easy to hold the handle 18 by pulling the string in the case of missing the handle 18 of the board body 10 during the play by configuring to be able to connect to the hand.

In addition, the rear end of the board body 10 is preferably provided with a guard 82 made of a thin cloth or vinyl, etc., the guard 82 is a guard receiving groove formed in the rear end of the board body (10) It is configured to be able to fold 13), the guard receiving groove 13 is good to have a structure that can be opened and closed by the cover (80).

In addition, it is preferable to form a predetermined groove (not shown) on the side of the board body 10 in order to be able to store articles, such as a whistle, necessary for playing in the water, and the groove can be opened and closed by a cover 84. It is good to have.

Further, the board body 10 is wound on one side of the back or front of the board body 10, and the structure of the string can be unwound and one end of the string is fixed to the other side so that the board body 10 can be fixed if necessary. It may be made to move on the shoulder of a user.

The operation of the present invention with the above configuration will be described.

The water board of the present invention moves on the water by the propulsion force of the propeller rotated by the drive motor, the user can play in the water floating on the water with the board hanging on the board.

The water board of the present invention can be configured to vary the conditions of weight and buoyancy to meet the various physical conditions of the user, and the propulsion of the propeller can also be manufactured to have a variety of conditions to suit the age of the user.

To play with the board, by pressing the switch provided on the handle 18 to rotate the propeller 40, the propulsion force is generated by the rotation of the propeller 40, the board body 10 is moved at a desired speed.

In particular, the present invention prevents the safety accident by the propeller 40 is accommodated inside the board body 10 is not exposed to the outside.

And, the direction of travel of the board body 10 can be adjusted while the user changes the load to the body, the board body by inadvertent operation by setting the propulsion force by the water discharged to the left and right of the board body 10 differently If the board (10) is missed, the board body (10) has a circular path of a predetermined size and returns to the user, thereby having a safe water play effect.

In addition, in the case of speeding up the movement of the board body 10, as shown in FIG. 5, the cover 80 is opened to spread the guard 82, and the current is prevented by placing the guard 82 at the bottom of the user. You can prevent the collision directly to the abdomen.

And, when a failure occurs by the drive means having a structure that is easily disassembled from the board body 10, which is a part of the possibility of failure, the repair can be made simply and quickly, the board body 10 Open the cover (60) covering the groove 12 of the, the belt connecting the propeller and the drive motor 50 is separated from the shaft of the drive motor 50, and then the housing 70 is the outer of the groove 12 Can be removed to repair the components that make up the drive. Of course, if the repair is made, it is possible to simply assemble in the reverse order.

When the battery 52 is to be charged, the plug 64 is opened to open the through hole 62 of the cover 60, and then the charging plug is inserted into the battery 52 through the through hole 62. By connecting, charging of the battery 52 can be performed simply.

According to the water board having a propeller of the present invention having the above configuration, the propeller is rotated by the drive motor to obtain a propulsion force and has a light and low-cost manufacturing effect by a simple structure for operating the drive motor with a battery.

In addition, the propeller of the present invention is not exposed to the outside to prevent safety accidents have the effect that even inexperienced users such as children can play safely and fun playing in the water.
