Water spouting device

摘要

The present invention provides a water spouting device which enables air bubble entrained water with an increased entrainment rate of air bubbles to be discharged at a low flow rate stage even though the user adjusts the flow rate based on the same feeling as that for a conventional water spouting device, the present water spouting device further enabling, at a high flow rate stage, prevention of discharge of air bubble entrained water with such a total amount as makes the user feel that the resultant amount of water significantly exceeds that intended by the user. A spout cap BC serving as the present water spouting device includes a pressure reducing portion 30 serving as an entrainment rate adjusting portion to adjust the entrainment rate of air bubbles entrained in air bubble entrained water in an air bubble entraining portion 703. The pressure reducing portion 30 serving as the entrainment rate adjusting portion increases the entrainment rate until inflow water from an inflow port 101 reaches a predetermined flow rate, and suppresses an increase in entrainment rate when the inflow water from the inflow port 101 exceeds the predetermined flow rate.

主权项

1. A water spouting device comprising:
a main body portion with a discharge port formed therein and from which water is discharged, an inflow port formed therein and into which the water to be discharged from the discharge port flows from a water supply source, and an internal channel formed therein and extending from the inflow port to the discharge port; an orifice portion configured to inject the inflow water from the inflow port toward a downstream side of the internal channel; an air bubble entraining portion with an opening portion formed therein and through which air is introduced into the internal channel, the air bubble entraining portion entraining the air introduced from the opening portion into the water injected from the orifice portion to generate air bubble entrained water and supplying the air bubble entrained water to the discharge port; an entrainment rate adjusting portion having a member in order to change a channel structure of the water spouting device and configured to adjust an entrainment rate of the air bubbles entrained in the air bubble entrained water in the air bubble entraining portion, the entrainment rate adjusting portion increasing the entrainment rate until the inflow water from the inflow port reaches a predetermined flow rate, and suppressing an increase in entrainment rate automatically, without manual operation by a user, when the inflow water from the inflow port exceeds the predetermined flow rate; and a biasing device which provides the suppression of the increase in entrainment rate.
