Description

BACKGROUND OF THE INVENTION Field of the Invention [0001] The present invention relates to a foot bath with microbubbles generating and circulating means,

BACKGROUND OF THE INVENTION 1. Field of the Invention [0001] The present invention relates to a footbath provided with micro-bubble generating-circulating means, more specifically, a footbath provided with a machine room inside a body constituting a footbath, a plurality of connecting pipes provided in the machine room, By connecting the compression tank and the bubble generating nozzle unit, microbubbles are generated while the bath water filled in the foot bath body passes through the oxygen air compression tank, the bubble generating nozzle unit, and the respective connection pipes, and the microbubbed water bath To a foot bath provided with micro-bubble generation-circulation means which can keep the temperature of water constant by repeatedly circulating the water by compression and expansion.

In general, a foot bath promotes blood circulation, thereby enabling the patient to excrete the unnecessary substances, harmful substances, and waste materials accumulated in the body, and thereby to prevent hypertension, hypotension, constipation, insomnia, headache, anemia, chronic fatigue, Impotence, neuralgia, back pain, arthritis and prevent diseases.

In addition, a foot bath with a foot in hot water will remove the cold air inside the body as the blood staying in the foot warms up. When the foot bath is used, the foot warms up to the body as well as the body, and the narrowed blood vessel widens again. The blood flow that is stagnated in the area is promoted. As the blood circulation gets better and the body warms, the metabolism is activated, and the waste in the body is discharged out of the body with sweat. It helps to relieve the tension of the brain and relax the whole body, which helps to take a good night's sleep. Especially, for those women who are cold or limb-cold with cold hands and feet,

As described above, due to the effect on the foot bath, a variety of foot baths have been developed in order to maximize the effect of the foot bath.

A foot bath is a device that cleans the feet of the body most distant from the heart so that blood circulation is relatively uncomfortable. Such foot baths generally have a function of heating the wash water and an aeration function, Massa

It is possible to provide a ground effect. In recent years, for example, there have been added functions for generating ultrasonic waves in a foot bath accommodating wash water to impart physical stimulation to the feet, and for forming feet in the foot bath to perform foot massage.

      These functions newly provide a new perception that the footbath is a simple device that can only perform foot cleaning, promotes fatigue recovery, and plays a role as a health supplement that can make the physiological functions of various books easier . Therefore, when the interest in health is concentrated recently, the demand for foot bath is increasing as a health supplement.

However, in the case of a generally used footbath, when the container is filled with hot water and the feet are soaked, the temperature of the water is lowered over time even if the water is hot, and the effect of the padding is lost. In controlling the firing temperature, it is difficult to maintain a constant firing temperature because it is too hot at first and too cold later, and there is provided an electric heater and an electric leakage preventing device provided for controlling the temperature, but there is still a safety risk.

In order to solve the above-mentioned problems, the present invention provides a method of connecting an air compression tank to generate fine bubbles in a connection pipe so that the temperature of water can be maintained constant over time, The bubble generating nozzle unit is connected, and the micro-type water generated by passing through the air compression tank, the bubble generating nozzle unit, and the respective connecting pipes repeatedly compresses and expands to further compress and expand the water that has been pulverized or unmixed And a micro-bubble generating-circulating means for circulating the water mixed with the pulverizing and maintaining the water temperature at a constant level.
