Abstract
An automatic birdbath filling system (10) and method are provided in which a water control valve (22) is controlled by a water level switch (32). The water level switch (32) and its holder (34) are placed, without the need for fixation devices, into a birdbath (12), thus allowing for existing birdbaths to be easily converted into automatically filling birdbaths.
Claims21
An automatic birdbath filling system, comprising:
- a water supply;
- a sensor operable to sense at least one water level;
- a power source;
- an electrically operated valve coupled to the power source and the water supply, the electrically operated valve opening in response to the sensor sensing a low water level;
- and
- a leveling system coupled to the sensor.
An automatic birdbath filling system, comprising:
- a water supply;
- a sensor operable to sense at least one water level;
- a power source;
- an electrically operated valve coupled to the power source and the water supply, the electrically operated valve opening in response to the sensor sensing a low water level;
- and
- a height adjustment system coupled to the sensor.
An automatic birdbath filling system, comprising:
- a water supply;
- a sensor operable to sense at least one water level;
- a power source;
- an electrically operated valve coupled to the power source and the water supply, the electrically operated valve opening in response to the sensor sensing a low water level;
- and
- a sensor housing coupled to the sensor, the sensor housing having a weighted base.
An automatic birdbath filling system, comprising:
- a water supply;
- a sensor operable to sense at least one water level;
- a power source;
- an electrically operated valve coupled to the power source and the water supply, the electrically operated valve opening in response to the sensor sensing a low water level;
- a birdbath bowl;
- and
- a sensor housing coupled to the sensor, the sensor housing located in but unattached to the birdbath bowl.
An automatic birdbath filling system, comprising:
- a water supply;
- a sensor operable to sense at least one water level;
- a power source;
- an electrically operated valve coupled to the power source and the water supply, the electrically operated valve opening in response to the sensor sensing a low water level;
- and
- a flow control valve downstream of the electrically operated valve, the flow control valve operable to control water flow rate.
A method of automatically filling a birdbath, comprising:
- supplying water;
- placing a sensor in a birdbath bowl, the sensor sensing at least one water level;
- electrically opening a valve in response to the sensor sensing a low water level to allow the supplied water to flow into the birdbath bowl;
- and
- leveling the sensor.
A method of automatically filling a birdbath, comprising:
- supplying water;
- placing a sensor in a birdbath bowl, the sensor sensing at least one water level;
- electrically opening a valve in response to the sensor sensing a low water level to allow the supplied water to flow into the birdbath bowl;
- and
- adjusting the height of the sensor.
A method of automatically filling a birdbath, comprising:
- supplying water;
- operating a sensor in a birdbath bowl, the sensor sensing at least one water level, wherein the sensor is unattached to the birdbath bowl;
- and
- electrically opening a valve in response to the sensor sensing a low water level to allow the supplied water to flow into the birdbath bowl.
A method of automatically filling a birdbath, comprising:
- supplying water;
- placing a sensor in a birdbath bowl, the sensor sensing at least one water level;
- electrically opening a valve in response to the sensor sensing a low water level to allow the supplied water to flow into the birdbath bowl;
- and
- controlling water flow rate downstream of the electrically operated valve.
An automatic birdbath filling system, comprising:
- a water supply;
- a birdbath bowl;
- a sensor operable to sense a low water level, the sensor located in but not attached to the birdbath bowl with any device that alters the birdbath bowl;
- and
- a valve coupled to the water supply, the valve opening to allow the water supply to supply the birdbath bowl in response to the sensor sensing the low water level.
