Abstract
Plant watering device (2) comprises two components (A & B). Component (A) comprises an inverted ring shaped bowl (4) with a hole (8) in its upper surface which serves as a filling port. A bung (10) is adapted to fit into and seal the filling port (8). A small delivery port (12) is provided in the bottom of pot chamber (6). Component (B) is a sealing disc (14). The outer rim of the sealing disc (14) is adapted to form a watertight seal with the base of bowl (4) whilst allowing rotation of the two components (A & B) relative to each other. An inner circular upstand (16) is provided in the centre of sealing disc (14) and has a delivery port (18) which corresponds in size and shape to the delivery port (12). In use, the delivery ports (12, 18) are aligned, which allows water to flow out from the water reservoir (20). As the reservoir (20) is a sealed chamber, water can no longer leave it. Hence, the water level in the plant chamber (6) is maintained within close limits about the height of the delivery ports (12, 18).
Description
DESCRIPTION An Automatic Plant Watering Device
Technical Field
The invention relates to plant watering devices, and more particularly to a watering device which automatically maintains the water level in a plant container.
Background Art
Some automatic plant watering devices are known. For example, some devices comprise a soil containing compartment and a water reservoir, connected to each other by a wick. The wick absorbs water and hence transfers water from the water reservoir to the soil. Others have complicated valve systems to regulate water flow or levels, or to permit filhng of water reservoirs.
Known plant watering devices have a number of disadvantages. For example they are not always very efficient at water transfer and the wick may deteriorate with time.
It is therefore an object of the present invention to go some way in overcoming at least some of the disadvantages with known automatic plant watering devices, or to at least provide the public with a useful choice.
Disclosure of Invention
The present invention provides an automatic plant watering device consisting of a container having relatively movable parts which regulate, or which may be actuated to regulate, the level of water for a plant or plants.
The improved automatic watering device possesses the advantage of a maintained and easily adjustable water level, and easy filling of the water reservoir.
Claims
1. A plant watering device comprising: a sealable water reservoir, a plant chamber, and a valve; the valve positioned and arranged between the water reservoir and the plant chamber such that when the valve is in an open position; and the reservoir is sealed, water from the reservoir flows from the reservoir into the plant chamber and air flows from the plant chamber into the water reservoir until the water level in the plant chamber is higher than the valve.
2. The plant watering device of claim 1 wherein the valve is adopted to be open and closed and/or the level set by adjusting the position of the plant chamber with respect to the components of the water reservoir.
3. The plant watering device of claims 1 or 2 wherein the valve is formed as part of the components of the reservoir, preferably the valve comprises a hole or slot, extending between and into both the plant chamber and the water reservoir.
4. The plant watering device of claims 1, 2, or 3 comprising two main components each with a circular base; an upper component having a depressed centre forming the plant chamber, and a lower component forming a base of the device.
The outer rim of the base preferably fits closely to the lower rim of the base of the upper component, forming a watertight seal.
More preferably the lower component includes an inner circular upstand which may fit closely to the base of the plant chamber within the upper component. It is specially preferred that a hole or slot is positioned within the circular upstand. Also a hole or slot may be positioned in the lower periphery of the plant chamber which fits within the inner circular upstand of the lower component.
Preferably the water reservoir is positioned within an area in the upper component. The water reservoir may surround the plant chamber , such that when the upper component is placed over the lower component, the base of the plant chamber fits within the upstand in the lower component. Preferably both the lower part of the plant chamber and the upstand have a hole or slot. The two holes or slots may be aligned or misaligned. The holes or slots may be misaligned by turning the upper component in a circular manner with respect to the lower component.
Preferably a fill port is provided in the upper surface of the upper component. More preferably a bung is provided to seal the fill port.
