Description

[Detailed description of the invention] [Field of industrial application] The present invention mainly focuses on creating air bubbles that can be used for pine surge while floating on top of hot water during bathing and discharging a stream of hot water mixed with air bubbles towards the bather's body. It relates to an incoming water flow generator.

[Conventional technology]

In conventional bathtubs, compressed air is sent into the hot water stored inside the bathtub to create a stream of hot water mixed with air bubbles, and the hot water stream massages the bather's body to promote blood circulation. , some are designed to help improve health.

[The problem that the idea is trying to solve]

The problem with the bathtub is that it cannot be easily installed in an ordinary household because it requires large-scale equipment and a large amount of cost.

On the other hand, as an idea for a bubble-containing water flow generator that can be carried and used in a bathtub, there are ideas described in JP-A No. 64-86970, JP-A-62-116728, and JP-A-56-143166. However, these devices simply eject a stream of water containing bubbles from the main body, and are not as interesting as toys for children to play with by moving the main body around in the water in the bathtub or hot water.

The main purpose of this invention is that it can be easily carried to the bathtub,
To provide a bubble-containing water flow generator capable of performing pine surge while discharging a bubble-containing water flow or a warm water flow toward a bather's body, and which can be used as a toy for children to enjoy playing in water or bathing in a bathtub. The purpose is to

[Means to solve the problem]

In order to achieve the above object, the present invention includes a small motor, a pump driven by the small motor, and an electrical connection to the small motor via a switch, inside a main body that floats on water. a battery, a cavity communicating with a water inlet provided at the bottom of the main body, and a water supply channel communicating with the cavity and supplying water from the pump to the rear end of the main body;
A ventilation hole communicating with the water supply channel is provided, and a water discharge pipe swinging like a rudder is attached to the end of the water supply channel.

[Effect]

When the main body is floated on water or hot water stored in a bathtub, water or hot water flows into the cavity inside the main body.
In this state, when you turn on the switch, the small motor rotates and drives the pump.At the same time, the pump sends water through the water supply channel, and at the same time, the water pressure sucks outside air into the water supply channel through the vent hole. The outside air becomes bubbles and mixes into the water supply, and is discharged from the water discharge pipe as a bubble-containing water stream or a hot water stream. In this state, if the bather holds the body with his/her hand and points the water discharge pipe toward his/her body, the bubble-filled water stream or warm water stream will hit the body and cause a massage, and if the bather removes his/her hand from the body, the bubble-filled water stream will flow. Alternatively, the main body moves around on the water surface or hot water surface using the hot water flow as power.

15 into the water supply as air bubbles, and is vigorously discharged from the water discharge pipe 97 as a hot water stream 151 containing air bubbles. In this state, the bather can perform pine surge by holding the hollow body 1 with his/her hand and applying the warm water flow 151 to his/her body.If the bather releases his/her hand from the hollow body 1, the hot water flow 151 It receives power from 151 and moves on the warm surface like a toy boat. In this case, the water discharge pipe 97 acts as a rudder, and if it is locked straight,
The hollow body 1 moves straight, and when the water discharge pipe 97 is swung to the right or left by an appropriate angle and locked, the hollow body 1 moves to the right or left.

[Effect of idea]

Since the present invention is constructed as described above, it can be easily carried in a bathtub and floated on the water or hot water stored in the bathtub to generate a stream of water containing bubbles or a stream of hot water. Not only can the water flow or warm water flow massage the bather's body to improve blood circulation and improve health, but children can also use the cap, front cover, wing pieces, and tail cover on the disc-shaped body in the bathtub. Attach and detach as appropriate. Turn the water discharge pipe to the desired angle and lock it, and use the bubble-filled or warm water flow as power to move the disc-shaped body around as you like, allowing you to play in the water or take a bath. It has the advantage that it can also be used as a fun toy.
