Description of the Related Art Conventionally, by incorporating a constant flow rate valve at the end of a water faucet portion of a faucet, a constant amount of hot water can be constantly spouted even when the water supply pressure fluctuates, so that the water discharge range can be kept within a predetermined range. FIG. 2 of Japanese Patent Application Laid-Open No.
(FIG. 4 of the present application). Briefly describing FIG. 4, a bush 32 is inserted into and connected to the tip of the faucet body 31, a water discharge cap 33 is coaxially connected to the bush 32, and a constant flow rate is provided inside the water discharge cap 33. The valve 34, the rectifier 35, and the rectifier network 36 are sequentially arranged and incorporated. Since the rectifier 35 that provides a flow path resistance so as to attenuate turbulent flow is disposed immediately downstream of the constant flow valve 34, Water splashing is small and stable water discharge is obtained.

The core 15 and the O-ring 16 are accommodated in a cylindrical housing 14 which is supported by being sandwiched therebetween, and a hot water flow path 17 is formed between the core 15 and the O-ring 16. . Although the supply pressure of the hot water passing through the flow path 17 is low or the O-ring 16 does not deform in a normal case, the flow path 17 maintains a predetermined water flow area, but when the supply pressure increases, the pressure changes. O-ring 16 is formed in flow path 17
This is a conventionally known device capable of constantly discharging a fixed amount of hot and cold water to the outside even when the supply pressure changes, by reducing the water flow area by deforming in a direction to close the water.

Step 8 formed on the inner peripheral surface of the water discharge section 5 and the packing 19
A gap 22 is formed between the outer peripheral surface of the foam metal fitting 20 and the inner peripheral surface of the water discharging section 5 for introducing outside air into the foam metal fitting 20. In the inside of the foam metal fitting 20, a wire mesh 23 having a raised central portion to secure a water flow area and a disk 24 having a number of small holes 25 formed therein for accelerating the change of hot and cold water into a thin flow are accommodated. . The gap 2
A plurality of mesh plates 27 for stirring hot water and foaming the hot water are stacked and accommodated downstream of the air holes 26 communicating with the second and introducing the outside air. Therefore, hot and cold water flows through the constant flow valve 13.
When the air reaches the foam metal fitting 20 from outside, the outside air is sucked into the foam metal fitting 20 from the gap 22, and the hot water mixes with the outside air to form the mesh plate 27.
While passing through, the foam flow is discharged to the outside.

ねの少ない泡沫水を吐水することができる。When the lever 4 is operated from the water stop position in the water faucet 2 in the water discharge direction, the hot water first passes from the outside to the inside of the strainer 9, and any foreign matter mixed in the hot water at this time is sent to the strainer 9. Be captured. Next, the hot water flows through the flow path 1 by deforming the O-ring 16 even if the supply pressure of hot water changes between the core 15 of the constant flow valve 13 and the O-ring 16.
7 is controlled to a constant flow rate by changing the water passage area, and the hot water that has passed through the constant flow rate valve 13 is foamed by the foam fitting 20, so that the foam water with less water splash can be discharged.
