Note that the switch 87 pressed by the manual push button 91 may be built into an underground hygrometer, a solar radiation indicator, or the like, so that water is supplied depending on the humidity of the water sprinkler or the amount of sunlight during watering.

In the above description, a water sprinkler for a garden or the like is described using water as the fluid, but it may be connected to other timed water supply pipes and used for timed water supply control.

Since the present invention is configured as described above, water supply can be started manually or automatically when water supply is required by turning the knob on the control box, or the knobs on the control box and timer case, or operating the manual push button. Water can be supplied for a set time using the rotational force of a water wheel installed in the pipe as a drive source, and an electric motor is not used as the drive source for the water supply timer, so water supply time can be controlled with less power.

Also, when used as a water supply timer for a water sprinkler, water can be sprinkled at a constant flow rate at an appropriate time, so the amount and time of watering do not vary depending on the person, and there is no need to be constantly involved in watering work. As a result, watering work is labor-saving.

In addition, water supply timer devices such as water sprinklers can be used to provide excellent effects such as being able to perform appropriate water sprinkling while the user is away, and contributing to water conservation through efficient water use.
