Description

    The present invention generates microbubbles from a gas such as air dissolved in a liquid when a liquid such as tap water is discharged from a faucet with a swing pipe, and easily swings attached to the faucet with a swing pipe. The present invention relates to a microbubble generator for a faucet with a pipe and a faucet with a swing pipe incorporating the microbubble generator.

  Research on microbubbles started around 1985. Since microbubbles are a new technical field, there are many unexplained points. Currently, the following two phenomena are known for microbubbles.

  One is a permeation phenomenon in which the microbubbles are small in size, so that they can easily penetrate into fibers, pores, and the like. Another is crushing. Crushing is a phenomenon in which microbubbles are discharged into the water and are crushed by the water pressure in the water to become smaller nanobubbles that are eventually destroyed. It is said that when this crushing occurs, an ultrasonic wave of about 400 km / h is generated and a high heat of nearly 5500 degrees is generated. And it is said that dirt and the like are easily removed by the interaction of these two phenomena.

  As other specific use cases, in the fisheries field, examples of growing freshwater fish and saltwater fish simultaneously by generating microbubbles in water, examples of preventing oyster red tide damage, and examples of improving scallop aquaculture efficiency Etc. have been reported.

  In the ship field, there is a research to reduce the resistance of the ship by flowing microbubbles to the bottom of the ship and increase the speed of the ship. In the field of automobiles, a technique for improving combustion efficiency by injecting a mixed fuel containing air through an internal combustion engine (engine) through a microbubble generator has been studied.

  In addition, shower heads with devices that take in air from the atmosphere and generate microbubbles are on the market. Furthermore, circulating microbubble generators for bathtubs are also sold.

  As described above, utilization and research on microbubbles are performed in a wide range of technical fields.

  Here, as a means for generating microbubbles, about nine types such as a high-speed shearing method, a pressure crushing method, and a cavitation method are known. Many of them draw air from the outside by an aspirator method or the like. Or forced injection.

  On the other hand, Patent Document 1 discloses a cavitation-type microbubble generator that generates microphone bubbles from dissolved air without inhaling air from the outside.

  The microbubble generator of Patent Document 1 has a simple structure that does not require a swirling flow by a high-pressure pump, and uses cavitation that occurs when a high-speed water flow passes through a plurality of nozzles arranged at narrow intervals, (A) a first nozzle 3 on the water inlet side that gradually reduces a cross-sectional area perpendicular to the central axis from the inlet 2e toward the outlet 2f; and (b). The first nozzle 3 on the inlet side is continuously disposed through the communication passage 8 and gradually increases in cross-sectional area perpendicular to the central axis from the inlet 4e toward the outlet 4f. It has two nozzles 4 and (c) a side chamber 8b opened only in the communication path 8.

  However, sufficient proposals have not been made for a means for simply arranging the microbubble generator in an existing pipe and a specific practical example using an existing liquid fluid.

  On the other hand, Patent Literature 2 discloses a shower head in which a venturi tube 1 is built in a shower head and microbubbles are generated. However, the Venturi tube 1 locks the Venturi tube 1 by locking the rubber packing 7 to an annular projection that is not normally present in the shower head, and stops water. Therefore, there is a need for a custom-made (with internal annular protrusion) showerhead that is specific to the invention.

  Therefore, the present inventor has already invented the microbubble generator disclosed in Patent Document 3. The microbubble generator of Patent Document 3 is a microbubble generator that generates microbubbles from a gas-dissolved liquid, and a microbubble generator that generates a microbubble through a groove formed in the outer periphery and through the liquid. A cylinder having a path, and an O-ring fitted in the groove and having elasticity, and disposed in a liquid-feeding pipe for flowing the liquid to a liquid-feeding place. It is characterized by sealing the gap.

  However, the invention of Patent Document 3 involves cutting or removing the pipe on the upstream side of the mouth of the faucet and attaching it, which involves complicated work.

  On the other hand, as a faucet, for example, a faucet with a swing pipe shown in FIG. A conventional faucet 20 with an oscillating pipe includes a faucet 21, an oscillating pipe 25, a cap nut 26, a U packing 27, and a ring 28.

  The faucet 21 is provided with a flange 22a that is engaged with a pipe hole formed in a wall or a counter on the upstream side, a mouth portion 24 that is a liquid discharge port at the other end, and an internal flow rate at the position of the top. It comprises a main body 22 having a flow path for adjusting the position and a handle 23 for adjusting the position of the frame by rotation.

  The mouth portion 24 includes a mouth portion having an outer screw portion 24a on the outer periphery, a ring-shaped inner first step portion 24c on the inner periphery, and a ring-shaped inner second step portion 24d located behind the inner first step portion 24c. Discharge the liquid. There is a faucet without the inner second step portion 24d. Conventionally, the inner second stepped portion 24d has prevented the swing pipe 25 from entering the faucet 21. Recently, however, the ring 28 alone can sufficiently prevent the swing pipe 25 from entering and dropping out of the faucet. It can be prevented.

  The oscillating pipe 25 includes a concave portion 25b that is recessed in a ring shape toward the inside, and the end portion 25a does not enter the faucet 21 by contacting the inner second stepped portion 24d. The U-packing 27 is a ring-shaped packing that is fitted to the oscillation pipe 25 and contacts the first stepped portion 24 c of the mouth portion 24. The ring 28 fits into the recess 25 b and contacts the U packing 27 and the tip 24 b of the mouth 24. The cap nut 26 has a hole, the swing pipe 25 is passed through the hole, the ring 28 is accommodated therein, and the outer nut 24a of the mouth 24 is screwed with the inner screw 26a.

  The conventional faucet 20 with an oscillating pipe connects the oscillation pipe 25 to the mouth 24 in a rotatable manner by screwing the cap nut 26 to the mouth 24, and the cap nut 26 is connected to the U packing 27 and The ring 28 is pressed against the inner first step portion, and the connection portion between the mouth portion 24, the oscillation pipe 25 and the cap nut 26 is sealed by elastic deformation of the U packing 27 and the ring 28.

  In Patent Document 3, a simple means for attaching a microbubble generator using a common structure of the faucet 20 with the swing pipe has not been studied.
