[Conventional technology]

2. Description of the Related Art Various bubble devices are known that generate bubbles in a bathtub and stimulate the bather's body with the bubbles to improve health and skin cleansing.

BACKGROUND ART Recently, bubble generating devices that can be attached to existing bathtubs have been put into practical use in general household bathtubs, so-called indoor baths. Although these water pumps are electric, they are waterproof and have sufficient safety against electrical leakage. It is also easy to handle.

[Problem that the invention attempts to solve]

However, since it is rare for ordinary households to have a power outlet in their bathroom, most of them connect the power cord of the bubble generator to the power outlet outside the bathroom. Therefore, the bathroom door cannot be sealed while this device is in use, or construction work is required to run the power cord through the door or wall. This construction work is large-scale due to waterproofing and restoring the appearance of the room, which has the disadvantage of increasing construction costs.

It is an object of the present invention to provide a bubble generating device which can overcome this drawback, operate even when the bathroom is closed, and eliminate the need for the above-mentioned construction work.

[Means for solving problems]

In the present invention, a lift pipe, a lift pump that boosts the pressure of hot water drawn from the lift pipe, an electric motor that drives the lift pump, and a nozzle connected to the output port of the lift pump are mounted in a first housing. In the apparatus, the water pump sucks up hot water in the bathtub, and the water jet ejected from the nozzle generates air bubbles in the bathtub, wherein the electric motor is a DC motor and is separate from the first casing. The first housing and the second housing are connected by a waterproof cord that supplies the output current of the battery to the DC motor. The output side of the battery is equipped with a waterproof opening/closing switch provided on the surface of the second casing, the second casing is equipped with an electrical connector to which terminals of the battery are connected, and a charging device is connected to the electrical connector. The charging device is characterized in that the circuit is removably connected thereto, and the AC connector of the charging device can be removably connected to an indoor socket outside the bathroom.

It is preferable that the electrical connector is covered with a waterproof blind lid when not in use, and the opening/closing switch is preferably provided on the surface of the second casing.

Either the charging device is outside the second housing and the charging device circuit is the charging device output circuit, or the charging device is inside the second housing and the charging device circuit is the charging device input circuit. It is preferable that

[Effect]

The water pump of the bubble generator is driven by a DC motor. A battery is housed in a waterproof second housing as a driving source, and is connected to a first housing containing a water pump, a DC motor, etc. using a waterproof cord. Therefore, the second housing can be installed in the bathroom in the same way as the first housing. Since there is an on/off switch in the path of the battery's output current, the bather can freely operate the DC motor. After bathing, charging can be performed from a circuit outside the bathroom via a removable electrical connector provided in the second casing. You may leave the bathroom door open at this time.
