Abstract

<P>PROBLEM TO BE SOLVED: To provide a waterer roughly setting a quantity of water supply per day, and supplying water through dripping, through solving such problems that a conventional waterer using no motive power continuously supplies water through burying a water supply opening into the ground and using a capillary phenomenon, so it is difficult to adjust a water quantity to ooze out. <P>SOLUTION: This waterer is obtained by tightly passing a thin tube 2 through a cap of a hermetically-sealed container represented by a PET-bottle, pouring water into the container 1, and burying the one end of the tube 2 into water in the container 1 followed by tightening the cap. The waterer device is set on a water supply place. When sunlight is applied to the container 1, or a temperature in the container 1 rises with rise of outside temperature, air in the container 1 expands, and water is extruded from the tube 2 by the pressure and drips down from the end of the tube 4. The total quantity of water to be extruded per day is fixed by a daily difference of a volume of air put in the container 1 when setting and a temperature in the container. <P>COPYRIGHT: (C)2009,JPO&INPIT

Description

  The present invention relates to an apparatus for supplying water in a sealed container, such as a plastic bottle, through a tube whose one end is submerged in water under pressure due to the temperature of the air rising and expanding due to solar heat. Is.

Conventionally, Patent Document 1 discloses a water supply device for a plant in which a cap is specially devised using a water pressure by turning a plastic bottle upside down. Moreover, patent document 2 is disclosed as a water feeder to the plant using a capillary phenomenon.

  Conventional water feeders that do not use power have been continuously performed regardless of the positive input, because the water inlet is buried in the ground and water is supplied using the capillary phenomenon. In addition, it was difficult to adjust the amount of water that exudes from the water supply port. It is an object of the present invention to supply a large amount of water to the positive sunlight where animals and plants want water, set the amount of water supply per day roughly, and drop and supply water.

  In order to solve this problem, the invention of claim 1 is characterized in that a thin tube is passed through a cap of a container such as a plastic bottle, water is poured into the container, and one end of the tube is placed in the water within the container. Submerge and tighten the cap securely.

  Install this device in the water supply area. When the container is exposed to sunlight or when the temperature inside the container rises as the outside air temperature rises, the air inside the container expands and water is pushed out of the tube by the pressure and dripped from the tip of the tube. The total amount of water pushed out per day is determined by the daily difference between the amount of air that was in the container at the time of installation and the temperature.

  According to the present invention, it is possible to supply water and animals unattended by setting the amount of water supply per day for animals and plants by installing the apparatus avoiding direct sunlight in a place without irrigation equipment.

  By installing this device in a place where it is exposed to direct sunlight all day long, after the clouds are generated and the sun is shaded, water is supplied every time the sun is turned on again. can do.

  Moreover, it can be used as a summer watering device by adopting this installation method in urban areas.

  FIG. 1 shows one tube attached. Since water can be supplied by the number of tubes, the number of tubes is arbitrary in consideration of the size of the container and the amount of water supplied. However, each of the water supply amounts when there are a plurality of tubes is a fraction of the number of tubes.

Industrial applicability

  The present invention can be widely used not only for watering houseplants in homes and offices but also for watering seedlings in agriculture and forestry, and as a summer watering device in urban areas. And since it is a device that uses only solar energy as an energy source, it meets the demands of society where environmentally friendly efforts are required.

  FIG. 1 is a schematic cross-sectional view of the entire apparatus with one tube and about one third of water.
