Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a water supply device for a bottom water supply type flowerpot.

[0002]

2. Description of the Related Art In a bottom water supply device of this type, it is usually necessary to prevent atmospheric pressure from acting on the upper surface of the water in the water storage tank when replenishing the water in the water storage tank. This is because if atmospheric pressure acts, water will flow out of the water tank into the flower pot. Therefore, one method is to provide the water supply port of the water storage tank on the bottom surface of the water storage tank as well as the water supply port from the water storage tank to the flowerpot. In that case, when adding water, take out the water supply device from the flower pot and supply water with the bottom of the water storage tank facing up. Alternatively, a water supply port can be provided at the top of the water storage tank. In that case, a valve device is provided at the water supply port provided on the bottom surface of the water storage tank, and a mechanism for opening the water supply port only when the water storage tank is installed in the flowerpot is provided. In this case as well, the disadvantage is that the water must be replenished with the water supply port closed, so there is the annoyance that the water tank must be taken out of the flowerpot and replenished as with the first method. is there.

[0003]

According to the present invention, it is possible to realize a water supply device which overcomes the above-mentioned drawbacks of the water supply device for a bottom water supply type plant pot and does not need to take the water supply device out of the flower pot at the time of water supply.

Further, in order to increase the amount of water stored in the water storage tank and minimize the trouble of water supply, the capacity of the water storage tank is increased to increase the water storage amount.

If the water in the water storage tank continues to run out of water, the plants will fail. To prevent such a situation, the remaining amount of water in the water storage tank is detected by a simple method so that the timing (timing) of replenishing water can be known.

[0006]

[Means for Solving the Problems] A water supply port is provided on the upper surface of a water storage tank and can be opened and closed by a cap having a hermeticity so that air does not leak (air does not enter the water storage tank). . A water supply port will be provided on the bottom of the water storage tank. In the state where the cap of the supply port is not closed, the water supply port has a mechanism in which the valve presses the water supply port with an elastic material such as a spring to seal the water supply port, and water is not supplied to the flowerpot. Next, after the water is replenished to fill the water tank, the cap of the replenishing port is closed. At that time,
If you make it so that the upper end of the rod projects a little above the supply port, when the cap is attached to the supply port,
The rod is pushed down by the cap. As a result, if the lower end of the rod pushes down a part of the valve mechanism so that the valve is separated from the water supply port, the water supply to the flower pot starts from that point.

Next, the auxiliary water storage tank is provided with a water supply port on the upper surface thereof and a cap having an airtightness for opening and closing the water supply port. Then, a water outlet is provided in the lower portion, and a water channel is formed by a pipe between the water outlet provided in the lower portion of the bottom water supply type plant pot water supply device. In this way, by combining the auxiliary water storage tank with the water supply device for a bottom water supply type plant pot of the present invention, the water storage amount of the entire water supply device can be appropriately increased.

An object of the automatic water supply device for a flowerpot according to the present invention is to reduce the time and effort of watering above all.
For that purpose, it is important in use that it is possible to easily know the time (timing) when watering is necessary.
If the float is long enough to be restrained by the rod and can move up and down in the axial direction of the rod, and at least a part of the cap is transparent, the upper end of the float can be seen from the outside. From that position, it can be seen that the amount of water remaining in the water storage tank has become very small, and the timing of water supply can be known.

BEST MODE FOR CARRYING OUT THE INVENTION Embodiments of the present invention will be described with reference to the drawings. In FIG. 1, a replenishment port 2 is provided on the upper surface of a water storage tank 1, and a cap 2-1 is provided at the replenishment port.
Is attached. Precise screws are cut on the replenishment port and the cap, respectively, to maintain the airtightness during installation. The packing 2-2 made of an elastic material such as rubber is also provided for enhancing the airtightness and is not essential.

A water supply port 3 is provided on the bottom surface of the water storage tank, and the water supply port is closed by a spring 4-1 from the bottom surface of the water supply port by means of a valve 4 which presses the water supply port to prevent water from leaking. The structure is such that The packing 4-2 is made of a material such as rubber and is attached to the valve in order to improve the airtightness. In this figure, since the lower end of the rod 5 pushes down the upper part of the valve tool, the packing 4-2 separates from the bottom surface, the water supply port 3 opens, and the flowerpot 6
The soil is being supplied with water through the water inlet 1-1. As a result, water has penetrated into the soil in the flowerpot up to the water level indicated by the alternate long and short dash line.

The rod is installed at a position where the rod is linked to the lower part of the cap and the upper part of the valve tool while being slidable up and down by the rod support plate 1-2. Figure 2
FIG. 3 is a sectional view taken along line AA of FIG. 1.

FIG. 3 illustrates the cap removed. Rod 5 held down by the cap
The upper end of the valve is free, and as a result, the packing 4-2 of the valve device 4 in which the rod is no longer restrained is pressed against the water supply port by the spring 4-1 to close the water supply port. Only in such a state, the water can be supplied. If the water supply port is opened while replenishing, the water level in the flowerpot rises to the same level as the water level in the water storage tank under the influence of atmospheric pressure, which adversely affects plants such as root rot. Because.

As shown in FIG. 4, the rod and the cap may be integrally formed.

FIG. 5 is a plan view and an elevation sectional view of the valve device 4 and the packing 4-2.

FIG. 5 shows an example of the valve device. Packing 8 for lever 8 swinging around fulcrum 7
The end to which 1 is attached is pressed against the water supply port 3 by the spring 8-3 to close the water supply port 3.
When the cap of the supply port of the water storage tank 1 is tightened, the rod 5 is lowered and the other end 8-2 of the lever is pushed down, as a result, the packing 8-1 is separated from the water supply port 3 and water supply is started.

FIG. 6 illustrates the invention of claim 2. The auxiliary water storage tank 9 is also provided with a supply port 10, and a cap 10-1 in consideration of airtightness is attached. An outlet 9-1 is provided in the lower portion of the auxiliary water storage tank, and a water passage is formed by a pipe 11 between the outlet 9-1 and the inlet 1-3 provided in the lower portion of the water storage tank of the present invention.

The role of the auxiliary water storage tank is to ensure a sufficient water storage capacity of the water supply device in accordance with various shapes and sizes of the flower pot. Of course, the purpose can be achieved even if the capacity of the water tank of the water supply device is increased. But,
The advantage of using a common water supply system and changing the auxiliary water storage tank is that it is easier to handle the variety of flower pots and the cost is lower. Generally, the larger the capacity of the water storage tank, the more convenient it is because it does not require watering for a long time.

FIG. 7 illustrates the invention of claim 3. At least a part of transparent cap 12 and rod 1
2-1 is fixed, and a hollow float 13 is attached using the rod as a mandrel. Make the float hole diameter slightly larger than the rod diameter so that the float can slide freely up and down with respect to the rod.

When the water level in the water storage tank is high, the upper end of the float is brought into contact with the cap as shown in the upper diagram of FIG. 8. When the water level falls below the set value, Leave the top of the float clear of the cap as shown below. By looking at the position of the upper end of the float through the transparent part of the cap, it is possible to know when to replenish the water. The set value of water level can be adjusted by design conditions such as float shape (lower part is thicker than upper part), size (length, outer diameter, inner diameter) and float material (specific gravity). it can.

As shown in FIG. 9, there is also a method in which the rod 14 is hollow and the float 15 is enclosed inside. Water passage 14-
1 is a hole for putting water in the rod. The cap and the rod may be integrated as shown in the figure, or they may be provided separately. In the case of a separate body, it is necessary to fix the rod to the valve device 4 or provide a rod support plate as shown in FIG.

[0021]

The effect of the present invention is that when replenishing water in a water storage tank, it can be replenished only by removing the cap of the water replenishment port without taking out the entire water supply device from the flower pot, which is extremely useful. It is convenient, and the capacity of the water storage tank can be freely changed according to the shape and size of the flower pot, the type of plant, etc. by using the auxiliary water storage tank. That is, the remaining amount of water in the water storage tank can be detected only by looking from the outside, and the timing of water supply can be easily known.
