Watering device

Abstract

There was a problem where the water in the flower vases at the graves would run out, causing the flowers to wilt quickly. [Solution] The air inside the sealed container expands due to the rise in temperature caused by the sun, pushing out water during the day. At night, when the temperature drops, the air inside the sealed container contracts, drawing air in through the end of the pipe. This cycle is repeated once a day to automatically supply water to the flower vase.

Description

Technical Field

[0001] The present invention relates to a device for adding water to a tomb flower stand without power and automatically.

Background Art

[0002] The amount of water that can be put in a tomb flower stand generally becomes small and runs out in a short time, and there has been a problem that the flowers wither when the water runs out. To solve this problem, a device that automatically supplies water from a water tank when the water level decreases is known. (Patent Document 1) However, since the known technology supplies water by gravity, it is necessary to place the water tank at a higher position than the flower stand, and there is a drawback that it cannot be easily installed in an actual tomb.

Summary of the Invention

Problems to be Solved by the Invention

[0004] It is to provide a device for automatically replenishing water to a tomb flower stand.

Means for Solving the Problems

[0005] It is composed of a sealed container (1) painted in a color that easily absorbs solar heat and its lid (2), and a hollow pipe (3) that penetrates the lid or the sealed container body and reaches near the bottom of the sealed container. The space between the pipe and the sealed container or the lid is sealed so that there is no gap.

Effects of the Invention

[0006] Fill a sealed container with water, leaving a moderate amount of air inside, close the lid, and place it in a sunny spot near a flower vase. Insert the end of the pipe opposite the container into the flower vase. When exposed to sunlight, the temperature inside the sealed container rises, causing the air inside to expand. The expanded air pushes the water out, and the water flows through the pipe into the flower vase. [Brief explanation of the drawing]

[0007] [Figure 1] Example of the present invention when a hole is made in the lid [Figure 2] Embodiment of the present invention when a hole is made in the main body [Figure 3] Side view of an example of use of the present invention [Figure 4] Front view of an example of use of the present invention. [Example 1]

[0008] As shown in Figures 1 and 2, make a hole in the lid (2) or the body of the airtight container (1) of a container that can be sealed with a lid, and pass the pipe (3) through to near the bottom of the container. Seal the gap between the pipe and the hole with adhesive (6) so that air or water does not leak out. Put water (4) into the airtight container, leaving an appropriate amount of air (5), close the lid, and place it in a sunny spot near a flower vase. Insert the other end of the pipe (3) into the flower vase. During the day, when sunlight hits it, the temperature inside the airtight container rises, the air (5) expands, pressure is generated inside the container and pushes down the water level. The pushed-down water (4) flows through the pipe (3) into the flower vase. At night, the temperature of the air inside the airtight container drops, the air contracts, the pressure drops and outside air is drawn in through the pipe. Repeat this cycle, with one day being one cycle, until the water runs out, preventing the flowers from wilting due to dehydration. [Explanation of Symbols]

Claims

[Claim 1] A watering device consisting of a sealed container with a lid, painted in a color that easily absorbs sunlight's heat, through a hole in the lid or body, into which a pipe is inserted into the container, with one end reaching near the bottom of the container. The container is sealed to prevent air from leaking through the gap between the pipe and the hole in the lid or sealed container, and the other end of the pipe is inserted into a flower vase.
