(G) Effects of the Invention As described above, the present invention provides a pump means installed with the liquid suction port and gas discharge port submerged under the water surface in a bathtub, and a pump means connected to the pump means via a power cord. an air intake port is formed in a portion of the pump means located above the water surface, and the power cord is introduced into the pump means through the air intake port. and connected to the power section inside the pump means,
By connecting the tube that covers the cord and serves as an air inflow path to the air intake port, there is no need to extend the air intake port upwardly from the top of the pump means and support the pump means at the bottom of the bathtub. The cord and suction hose do not come out of the pump means separately, making it easy to use, and the tube also protects the cord. In addition to the above configuration, if a hose is attached to the gas/liquid discharge port of the pump means, the hose can be used for showering or pumping up remaining hot water, which has the effect of expanding the uses of the bubble generator.

Further, the engagement of the hooking member of the pump means with the receiving part of the hanger, or the engagement of the hanger with the spherical protrusion of the pump means makes it possible to orient the discharge nozzle of the pump means in various directions. It has the effect of making it possible to concentrate the bubbles on the body parts of the person.

In addition, the power supply section allows the hanger and pump means to be integrated into one unit, making it convenient for storage and transportation.

If the far-infrared ray generating means is provided downstream of the liquid suction port of the pump means, the hot water circulating in the bathtub can be sterilized and purified, and a warming effect on the human body can also be expected.
