By simply opening and closing the flow path and adjusting the water discharge amount, once the valve is opened, water will continue to be discharged unless the user operates the handle or lever to close the valve, and if the valve is forgotten to be closed, water may overflow around. The problem of making a very uneconomical mistake of leaving extra water and being charged a high water rate, and the flooded water wets the house material and has to pay a high repair cost There was a problem to say. The present invention was devised for the purpose of economically and effectively preventing forgetting to put out water or warm water in such a conventional faucet fitting without using a power source such as electricity or a battery. It also contributes to the saving of precious water resources and can prevent the damage to houses and household goods due to water overflow.

でもない。In order to achieve the above object, the first aspect of the present invention is to provide a water supply connection port, one end of which is connected to a water supply source, and the other end of which is a water discharge port that is open to the atmosphere.
In a water supply device including a valve having a closing mechanism in the middle of the water supply connection port and the water discharge port, and an operation lever connected to the valve, the closing mechanism rotates the handle using a spring as a drive source. It is characterized by having a delay timer part that works according to the following.When the user sets the water discharge time at any time and opens the valve, even if the user leaves the place, the spring will automatically close the valve if the set time comes. It is possible to prevent overflow of hot water and hot water. Needless to say, since this valve uses a spring as a drive source and does not use electricity or a battery, there is no fear of failure and there is no need to replace the battery, which is extremely economical.

い勝手がよい。According to a second aspect of the present invention, since a valve having an adjustable opening for adjusting the water discharge amount of the water supply device is provided separately from the valve having the closing mechanism, the user can set the water discharge time at an arbitrary time. Even if the valve is opened and moved away from the place, when the set time comes, the valve is automatically closed by the drive of the spring to prevent overflow of water or hot water, and the amount of water discharged can be adjusted, which is more convenient.

FIG. 1 shows an embodiment of the present invention. Water entering from the water supply port 2 of the water supply device main body 1 according to the present invention which communicates with a water supply source (not shown) is normally stopped at a position where the valve body 3 closes the valve seat 4 and is prevented from flowing out from the water discharge port 5. There is. By rotating a lever 8 mounted on an output shaft 7 of a timer driving means 6 having a spring (not shown) built therein, a gear 9 fixed to the output shaft 7 is mounted on an end portion of a valve shaft 11 of a valve body 3. The rotational force is transmitted to the gear 10 and the valve shaft 11 rotates. A male screw 12 is machined in the middle of the valve shaft 11, and is fitted with a female screw 14 machined in the support portion 13 of the valve shaft 11 of the water supply device body 1. As the valve shaft 11 rotates, Valve body 3 directly connected to this
Moves in a direction away from the valve seat 4 and starts discharging water from the water discharge port 5. The timer drive means 6 starts to rotate in the opposite direction by turning the lever 8 earlier to return to the original position by the spring, and after a predetermined time, the valve shaft 11 is rotated and axially moved via the gears 9 and 10. By pressing the valve body 3 against the valve seat 4, the flow passage is closed and the water discharge is stopped. Spout time is lever 8
It can be set arbitrarily according to the rotation angle of.

る。FIG. 2 shows another embodiment of the present invention. By rotating a lever 8 mounted on the output shaft 7 of the timer driving means 6 at a predetermined angle, a rotational force is applied from a gear 9 fixed on the output shaft 7 to a gear 10 mounted on the end of the valve shaft 11 of the valve body 3. Is transmitted and the valve shaft 11 rotates. A male screw 12 is machined in the middle of the valve shaft 11, and is fitted with a female screw 14 machined on the support portion 13 of the valve shaft 11 of the water supply device main body 1, so that the valve shaft 11 is rotated by the rotation of the valve shaft 11. Move in the axial direction. The valve body 3 mounted inside the water supply device main body 1 is rotatable and can slide in the axial direction, and a lever 21 is attached in the middle of one of the shafts protruding from the valve body 3. Further, its shaft end is connected to the valve shaft 11 by a coupling 20 which is separated from the valve shaft 11 but does not transmit the rotational force for transmitting the axial moving force of the valve shaft 11. The other end of the valve body 3 comes into contact with the valve seat 4 to act to close the flow of water supplied from the water supply source. The valve body 3 has a hollow cylindrical shape, and has a cylindrical valve chamber 101 provided inside the water supply device body 1.
It is rotatable inside and can slide axially.
Further, a flow rate adjusting hole 30 is opened on the outer periphery of the valve body 3, and the relative position with respect to the water supply port 2 is changed by rotating the valve body 3, and the opening area for the water supply port 2 is changed, so that the water supply port 2 is changed. The inflow from can be adjusted. In other words, the amount of water discharged from the discharge port 5 can be adjusted by moving the lever 21. In such a configuration, when the lever 8 is rotated to arbitrarily set the water discharge time to start water discharge, and then the lever 21 is rotated to adjust the water discharge amount, even if the user leaves the place, the timer driving means 6 is operated by the spring. In order to return to the original position, the lever 8 is first rotated to start rotating in the opposite direction, and after a predetermined time, the valve shaft 11 is rotated and moved axially via the gears 9 and 10 to move the valve body 3 to the valve seat 4 By pressing against, it is possible to close the flow path and stop the water discharge.
