The groundwater storage tank 60 is installed at the lower end of the housing 10, and communicates with the housing 10 by a plurality of discharge pipes 100.

One end of the plurality of discharge pipes 100 is in communication with the plurality of discharge ports 12 of the housing 10 so that a predetermined length protrudes inside the housing 10 (for the reason, the mixing pipe 20 is Radon gas in the groundwater introduced through is removed in the housing 10 is to be stored in the housing 10 for a predetermined time without being directly introduced into the groundwater storage tank 60 through the discharge pipe (100). In other words, when one end of the discharge pipe 100 is coupled to form the same plane as the bottom of the housing 10, the groundwater falling to the bottom of the housing 10 is directly through the discharge pipe 100 groundwater storage tank 60 Although it will be discharged to), because it is a form that protrudes a predetermined interval inside the housing 10 of the discharge pipe 100, in order to be discharged through the discharge pipe 100 as much as the height of the protrusion of the discharge pipe 100 in the housing 10. Groundwater in housing 10 Because the ground water is made in the form of water droplets by the mixing pipe 20, and the ground water is stored for a predetermined time in the housing 10 as long as the protruding length of the discharge pipe 100, the discharge pipe 100 is discharged. The other end of the plurality of discharge pipes (100) is to be built in the groundwater storage tank (60) so that the other end of the plurality of discharge pipes (100) has a shape that gradually decreases in diameter.

That is, the groundwater from which the radon gas is primarily removed from the inside of the housing 10 is stored on the bottom surface of the housing 10. When the predetermined height is filled up, the discharge pipe 100 protrudes in a predetermined length in the housing 10. Falling to the groundwater storage tank 60 through, when the drop, the other end of the discharge pipe 100 is gradually reduced in diameter due to the radon gas is primarily removed in the housing 10 to the groundwater storage tank ( Purified water discharged to 60) is sprayed in the form of droplets to release the radon gas still remaining in the purified water to the outside.

(In addition, according to an embodiment of the user, a filter net (not shown) is formed at one end of the discharge pipe 100 protruding in the housing 10, foreign matter such as rock powder existing in the ground water is filtered to store the ground water It is discharged to the tank 60. (The filter screen is made of stainless steel, but it may be variously changed by the user.)

And is electrically connected to the bubble tube 91 to supply air to the bubble tube 91 coupled to one end of the bubbler 90.

That is, when air is generated through the bubbler 90, the generated air flows through the bubble tube 91, and the bubble tube 91 is upright toward the bottom of the groundwater storage tank 60. After being embedded, the ground water storage tank 60 is arranged in the water from the bottom of the water from the bottom of the water to the top a number of times, the number of circles drawn by the bubble tube 91 is gradually increased in diameter according to the embodiment of the user The diameter of the circle formed by the bubble tube 91 may be variously changed according to the diameter of the groundwater storage tank 60.

As described above, a plurality of bubble holes 92 are formed in the outer periphery of the bubble tube 91 disposed in the water of the groundwater storage tank 60 and drawn through the bubbler 90 as described above. The air into which the introduced air is discharged to the outside through the bubble hole 92 generates bubbles in the groundwater storage tank 60.

That is, when a large number of small and large bubbles are generated in the groundwater in the groundwater storage tank 60, the bubbles rise above the water surface to flow the groundwater in the water, and the bubbles break on the water surface to spread the groundwater of the water surface into the air. will be. Thus, together with the discharge pipe 100, the radon gas is to remain in the upper side air inside the groundwater storage tank (60).

The second vent means 70 is installed in the second vent hole 61 installed in communication with the ground water storage tank 60 in an upright position, due to the use of the bubbler 90 and the discharge pipe 100, the ground water storage tank ( 60) to discharge the radon gas remaining in the upper air inside the secondary secondary to the first ventilation means 50 of the housing 10.

Of course, in the front of the second vent means 70, as in the first vent means 50, by installing a char filter 52 to be detachable from the second vent (61), in the ground water storage tank (60) Before the radon gas is discharged to the outside through the second ventilation means 70, the charcoal filter 52 allows the radon gas of a high level to be filtered first.

In addition, the second vent 61 is installed in the upright communication with the upper portion of the groundwater storage tank 60, the foreign matter and insects from the outside or rain, hail, snow and the like through the second vent (61) In order not to flow into the storage tank 60, the cover 62 of the hemispherical shape, such as '∩' is formed on the top of the second vent (61).

As described above, the external power supply device 80 is electrically connected to the bubbler 90 and the second ventilation means 70, so that the bubbler 90 and the second ventilation means 70 are driven. Supply power.
