Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a bubble generator for baths, and is intended to provide a device that consumes no power and has a simple configuration.

BACKGROUND ART Various bubble generating devices for bathing are already commercially available because generating bubbles in a bathtub and applying the bubbles to the body is very beneficial for restoring and promoting health and beauty. However, all of these systems use a blower or the like to forcibly send air to a bubble generator inside the bathtub, and then release bubbles from a bubble generating plate into the bath water, and these systems generally have a poor structure. It has the drawbacks of being complex, expensive, and consumes a lot of electricity. In order to solve this problem, as shown in Japanese Patent Application Laid-Open No. 55-78962, a bellows system that compresses air by actively moving the hands, feet, back, etc., and the air sent from the bellows. There is a body-pressure foaming ultrasonic health device that includes a porous body for extracting bubbles into a bathtub, and a tube connecting the bellows and the porous body. However, since the bellows and porous body of this health device are manufactured separately, it is troublesome to manufacture and maintain, and the bellows cannot be used by hand.
There are drawbacks such as the porous body moving in the bath if it is moved with the feet, back, etc. Therefore, the present invention eliminates these drawbacks and provides a product with a simple structure and low cost that does not use any electric power.The drawings showing the embodiments of the present invention will be described below.

1 is an air-tight air bag made of rubber, synthetic resin, etc. in a flat shape, contracts when a load is applied, and expands to its natural state when the load is removed;
A suction cup 3 is attached to the bottom of the air bag 1, and the suction cup 3 is attached to the bottom of the bathtub 2.
The well-known air cell disc 4 has numerous microscopic holes on its top that allow air to pass through but not water.
is tightly fixed. Reference numeral 5 denotes an air supply hose that projects upward from the side end of the air bag 1 and whose end extends downwardly outside the edge 6 of the bathtub 2; A one-way valve 8 that can supply air only to the air bag side is provided near the air inlet end 7 of the air bag. 9 indicates hot water.

Since the present invention has such a structure, the air bag 1 is fixed in the bathtub 2 with the suction cup 3 as shown in the drawing, and the air suction port end 7 of the air supply hose 5 is exposed outside the bathtub 2. Then, when the body is submerged in the hot water and placed on top of the air bag 1, the air bag 1 contracts due to its weight, and the air in the air bag 1 becomes bubbles from the bubble disk 4 and is released into the hot water. be done. Since buoyancy acts in hot water, a large load is not applied to the air bag 1, but you should float your body appropriately or put your feet on the left and right sides of the air bag 1 to prevent your entire weight from acting on the air bag. By adjusting the amount as appropriate, the amount of bubbles generated can be freely adjusted. When the bathtub is exited from the washing area, the weight acting on the air bag is removed, and the one-way valve 8 of the air supply hose 5 opens, allowing air to flow through the air supply hose 5 into the air bag 1.
Air is blown into the container, and it is ready for the next use. The present invention does not force air into the bathtub as in conventional products, so it consumes no electricity and is economical, and has an extremely simple structure, so it can be provided at low cost.

Claims (1)

[Scope of utility model registration request] The bottom part has a suction cup that sticks to the bottom of the bathtub, and the top part has a bubble disc with countless small holes that allow air to pass through but not water. Then, an air supply hose is installed at the side end of the airtight air bag, which expands to its natural state when the load is removed, toward the outside and downward of the edge of the bathtub. A bath bubble generator characterized by being equipped with a one-way valve capable of supplying air.
