Description

[Detailed description of the device]

[0001]

[Technical field to which the device belongs]

 The present invention relates to a flowerpot (box-shaped, that is, including a planter) equipped with an automatic watering device.

[0002]

[Prior art]

 BACKGROUND ART As an automatic watering device for a flower pot, a device which supplies water for a time by a hose laid from a water supply has been known.

[0003]

[Problems to be solved by the device]

 The above automatic irrigation system has difficulty in supplying an appropriate amount of water corresponding to the weather (clear rain, cold and warm) of the day, is likely to be too wet or too dry, and requires electric power to drive the system.

The present invention aims to automatically irrigate the culture soil in the flowerpot and maintain the moistness of the culture soil substantially constant without requiring any manual labor or electric power.

[0005]

[Means for Solving the Problems]

 The flowerpot of this invention comprises a container having a water reservoir at the bottom and an automatic watering device housed in the container. The automatic watering device consists of a nozzle connected to a water supply pipe directly connected to the water supply and a float. The water outlet of the nozzle is blocked by the buoyant force of the float when the water reservoir of the container is full of water.

An annular packing 27 may be attached to the outlet end of the nozzle 21, and a needle 24 having an outer diameter larger than the inner diameter of the nozzle 21 and a conical tip may be projected on the upper surface of the float 25.

The bottom of the container 1 can be provided with an overflow port 1 a projecting upward in a cylindrical shape.

The automatic watering device 2 is sealed except for the nozzle 21 and the water outlet 22, and the water outlet 22 is closely provided with a filter 23.

The needle 24 may be slidably inserted into a vertical through hole of a fixing plate 26 fixed to an upper inner wall of the automatic watering apparatus 2 and a supporting tube 26 a extending downward from the vertical through hole.

It is also possible to connect several containers 1 to each other in the water reservoir 1b, and set only one of the containers 1 to be the automatic watering device 2.

[0011]

[Embodiment of device]

 An embodiment of a flowerpot of the present invention will be described with reference to FIGS. 1 to 6.

This flower pot generally includes a container 1 having an overflow port 1 a projecting upward in a cylindrical shape at the bottom, an automatic watering device 2 housed inside a container 1, an automatic watering device 2 and a water supply. The water supply pipe 3 is connected between the water supply pipe 3 and the pipe 4.

The container 1 has a bottomed cylindrical shape, a box shape, or the like, and the shape is not particularly limited. Any material may be used as long as it does not seep out water, such as synthetic resin, ceramics, and metal.

A portion of the bottom of the container 1 below the upper end of the overflow port 1 a serves as a water reservoir 1 b in which water flowing out from the automatic watering apparatus 2 is accumulated. The overflow port 1a can be covered with a lid with packing. This is effective when the flowerpot is placed in a place where water should not be spilled, such as indoors. When the flower pot is placed outdoors, the lid may be removed because it may rain and cause excessive water content.

The automatic irrigation system 2 is provided with a nozzle 21 to which the water supply pipe 3 is connected at an upper part thereof, a water outlet 22 at a lower part thereof, and a filter which is circulated in close contact with each water outlet 22 inside. 23 and a float 25 projecting a needle 24 extending to the water outlet of the nozzle 21 are contained, and the parts other than the nozzle 21 and the water outlet 22 are hermetically sealed hollow containers. The cross-sectional shape of the automatic watering apparatus 2 is circular as shown in the drawing, but is not limited to this. Further, the height thereof is preferably slightly lower than the depth of the culture soil 5 put in the container 1. By doing so, the automatic irrigation device 2 is hidden in the culture soil 5 in the used state, so that it does not spoil the appearance. The filter 23 is for preventing the culture soil 5 from entering the automatic watering apparatus 2.

The needle 24 is slidably inserted in a vertical through hole of a fixed plate 26 fixedly provided on an upper inner wall of the automatic watering apparatus 2 and a support tube 26 a extending downward from the vertical through hole. The outer diameter of the needle 24 is larger than the inner diameter of the nozzle 21, and its tip is conically pointed as shown in FIG. An annular packing 27 made of rubber or the like is attached to the end of the water outlet of the nozzle 21 for receiving it. The length of the needle 24 can be raised and lowered in the automatic watering device 2 together with the float 25, and is determined by the level of the water level 28 in the automatic watering device 2. The water level 28 is set slightly lower than the water level 1c of the container 1, which is determined by the height of the cylinder of the overflow port 1a.

The water supply pipe 3 is directly connected between the automatic watering device 2 and the water pipe 4 without any other electromagnetic control valve or the like.

In the flower pot having such a configuration, the automatic watering device 2 is housed in a proper place of the container 1 as shown in FIG. 5, the culture soil 5 is put in the empty portion, and the plant 6 is planted. Be done.

When water is supplied to the water supply pipe 3 from the water pipe 4, the water enters the inside of the automatic watering device 2 through the nozzle 21, flows through the filter 23 and flows out of the water outlet 22 into the container 1. . The water permeates the culture soil 5 and permeates the culture soil 5, and then accumulates in the lower portion of the container 1 to form a water reservoir 1b. At that time, the water level 28 in the automatic watering device 2 also rises, and the float 25 floats up with it, and the needle 24 rises. Then, the tip of the needle 24 collides with the annular packing 27 at the water outlet end of the nozzle 21. Thereby, the outflow of water from the nozzle 21 is stopped.

The water thus accumulated in the water reservoir 1b is absorbed into the culture soil as the culture soil loses water due to evaporation and evaporation. When the water level 1c of the water reservoir 1b drops, the water level 28 in the automatic irrigation system 2 also drops, and the float 25 and the needle 24 go down again to bring the nozzle 21 into the water-passing state, and water is supplied in the same manner as described above. It In addition, excess water such as rain is discharged from the overflow port 1a. When the flower pot is placed indoors, it does not get rained, so the overflow port 1a may be used with the overflow port lid 7 covered.

The example of setting one automatic irrigation system 2 in one container 1 has been described above. However, several containers 1 are connected to each other by a pipe in the water reservoir portion 1b, and one container 1 among them is connected. Only one water irrigation system 2 may be set. In that case, the number of automatic watering devices 2 can be reduced, which is economical.

Further, although the tip of the needle 24 is conical in the above description (FIG. 6), the tip may be flat. If a rubber plate is attached to the tip of the needle 24 and the inner diameter of the nozzle 21 is made sufficiently small, the water pressure flowing out of the nozzle 21 can be sufficiently received by the buoyancy of the float 25. Further, instead of transmitting the buoyancy of the float 25 to the water outlet of the nozzle 21 via the needle 24, the buoyancy may be amplified and transmitted by applying the leverage principle.

[Effect of device]

 Since the present invention is configured as described above, it has the following effects.

That is, the culture soil in the flowerpot can be automatically irrigated without requiring any electric power or manpower, and the moistness of the culture soil can be kept almost constant at all times. Therefore, the optimum rooting condition of the plant is obtained, the growth is promoted, and the root rot and the overgrowth do not occur. Moreover, it does not require watering, no skill is required, and there is no loss of fertilizer due to watering.
