Abstract

PURPOSE:To increase air bubble generation efficiency in the system wherein air is drawn with a water flow jetted from a primary nozzle, and water and air are jetted from a secondary nozzle respectively for drawing air bubbles into a bath, by providing a rotary vane in a stage before the primary nozzle and causing the turning of a water flow. CONSTITUTION:An air bubble injector body 3 connected to the tip of a flexible water pipe 2 connected to a faucet 1 has a primary nozzle 7 for internally jetting water, and a secondary nozzle 9 at the downstream side of the nozzle 7 coaxial therewith. A space between the primary and secondary nozzles 7 and 9 is used as an air intake chamber 8, and one end of a flexible air pipe 10 with the other end open to the atmosphere as an air inlet 11 is open to the air intake chamber 8. In addition, the flexible air pipe 10 is retained in parallel to the flexible water pipe 2 with retaining pieces 12 and 13. In this case, the upstream side of the primary nozzle 7 is provided with a turning flow generator having screw threads 5 and 6 on the external surface thereof for giving an expansion angle theta of about 10 deg. to 20 deg. of a turning water jet from the primary nozzle 7.

に固定させるようにすることは自由である。The invention will be explained with reference to the drawings. FIG. 1 is a sectional view of an embodiment of the present invention. 1 is an arbitrary water faucet, and 2 is a flexible water pipe that sends water. 3 is a bubble injector body. Reference numeral 4 denotes a swirl flow generator that gives water flow a swirl around an axis, and has a large number of diagonal grooves 5, 6, etc. cut into a thread shape on its periphery. 7 is a primary nozzle, 8 is an air suction chamber, and 9 is a secondary nozzle. 10 is a flexible air pipe that sends air to the air suction chamber 8, 11 is an air inlet in the atmosphere, and the flexible air "W10" is a holding piece 12.13.
etc., in parallel with the flexible water pipe 2. Now, what is important about the present invention is that the swirling water jet 14 jetted from the primary nozzle 7 into the air suction chamber 8 becomes an expanded flow, and the expansion angle θ is about 10° to 20°. Adjust the size and inclination angle of the thread grooves 5, 6, etc. of the swirling flow generator 4, and set the opening size of the secondary nozzle 9 to a size that allows the swirling water flow 14 to pass through. . Further, 15 is water [l■] in the bathtub, and 16 is air bubbles on the water surface. The operation of this explanation will be explained. Now, when the water faucet is opened and water is sent to the bubble injector (body 3), the water flow first passes through the swirl generator 4, becomes a swirl flow, and is ejected from the primary nozzle 7 at an angle of about 0° to 20°. The water jet 14 with an enlarged angle passes through the secondary nozzle 9, but during that time it passes through the air suction chamber 8 and sucks air, which is faster than when the water does not swirl like in a conventional bubble injector. The expanded swirling flow according to the invention passes through the air suction chamber 8 with a large surface area, so it has a strong suction force and sucks in more air. Therefore, the present invention can form a bubble injector that can inhale a large amount of air with a relatively small amount of water flow, and is extremely safe and energy-saving since no electricity is used. In an experiment using an injector with a primary nozzle diameter of 2.6 mm and a secondary nozzle diameter of 6 mm, a swirl flow generator was installed and the expansion angle was 15 degrees.
When a jet of water is generated, compared to when no swirling flow is generated, although the water flow rate is reduced to approximately 75%, the amount of bubbles generated increases approximately three times, and a moderate oscillating flow is generated. It generated a feeling of pleasure to the human body. Therefore, in a bathtub in which bubble soap or the like is dissolved in advance, an extremely large amount of bubbles can easily be generated on the water surface by simply using hot water for a short period of time. This device blows a large amount of bubbles with a small amount of water from a faucet, and does not require electricity, making it possible to obtain a safe and convenient swirling water flow bubble injector. A floating body may be attached to the bathtub, and flexible suction cups may be attached to fix it to the wall of the bathtub.
