A negative pressure is formed in a large-diameter space in front of the nozzle portion by passing through the passage, and the outside air sucked from the air introduction hole by this negative pressure is mixed into the high-pressure water. In the front, a part where the high-pressure water flow passage is narrowed to a small diameter is required, and since the narrow high-pressure water flow narrows the once widened high-pressure water flow, the flow of the high-pressure water flow is reduced by half. there were.

とにある。[0005] Further, the negative pressure in the bathroom shower head described in each of the above-mentioned publications is improved when the high-pressure water jet sprayed from the nozzle portion spreads over a small-diameter portion. Since the negative pressure is formed in the large-diameter space on the side of the nozzle, the flow of the high-pressure water flow from the nozzle is too strong, or the air introduction holes are large and a large amount of outside air flows in. However, if the air does not spread completely to the small diameter, a sufficient negative pressure will not be formed, and the mixing amount of air and the size of the bubbles will become non-uniform, forming active water having vibration such as ultrasonic waves. There was a problem that you can not. The present invention has been made in view of the above points, and a purpose thereof is to provide a bathroom capable of stably forming active water having vibrations such as ultrasonic waves while maintaining a sufficient flow force. To provide a shower head.

きる。As described above, the bathroom shower head according to the present invention forms a large negative pressure in the pressure water passage by the high-pressure water jet injected from the injection port, and this negative pressure causes the air to flow from the air inlet hole. After aspirating the outside air as fine bubbles and mixing them into the high-pressure water stream, they are blown into the high-pressure water flow, and the fine bubbles mixed into the high-pressure water stream are crushed into ultra-fine bubbles. The active water that generates ultrasonic waves is formed so that the inside of the pressure water passage of the high-pressure water flow does not have to be narrowed to a small diameter as in the related art. A strong negative pressure can be formed.

However, the position where the high pressure water flow spreads completely in the pressure water passage automatically moves and a strong negative pressure is reliably formed in the pressure water passage, so that a strong negative pressure is reliably formed in the pressure water passage. You. This has the advantage that a large amount of outside air can be uniformly and stably mixed into the high-pressure water flow.

る。Further, the pressure water passage is formed in a straight tubular shape or a tapered tubular shape so as to be large on the side of the shower outlet, and the air inlet is formed so as not to protrude from the tip of the nozzle portion toward the shower outlet. That is, even when a load (back pressure) acts on the shower blowout hole or when the pressure of the high-pressure water fluctuates, the high-pressure water from the injection port easily flows backward through the air inlet and is discharged. There is an advantage that the conventional disadvantage can be solved.

The microbubbles in the high-pressure water stream are crushed into microbubbles by spraying them onto the surface, so that these microbubbles can be easily separated from the activated water even after being sprayed from the shower blowout holes. There is also an advantage that the properties of activated water that generates many ultrasonic waves and maintain ultrasonic waves can be maintained for a long time without separation.
