Description

本発明は植物の給水装置に関する。The present invention relates to a plant water supply apparatus.

従来の植物の給水装置には、水を入れたペットボトルを植木鉢等に差し込んだもの(例えば特許文献1参照。)や、植木鉢の底に水を入れて給水するようにしたもの(例えば特許文献2参照。)や、タイマ−を使って電磁弁を制御し給水するものがある(例えば特許文献3参照。)。又、毛細管現象を利用して水が蒸発することによる重量変化をテコの原理を利用して給水弁を開閉するものもある(例えば特許文献4参照。)。Conventional water supply devices for plants include a device in which a plastic bottle filled with water is inserted into a flowerpot or the like (see, for example, Patent Document 1), or a device in which water is supplied to the bottom of a flowerpot (for example, Patent Document) 2), and there is one that controls the solenoid valve using a timer to supply water (for example, see Patent Document 3). In addition, there is a type that opens and closes a water supply valve by utilizing a lever principle based on a weight change caused by water evaporation using a capillary phenomenon (see, for example, Patent Document 4).

以上述べた従来の給水装置では土壌が湿っていても常に給水されたり、タイマ−で強制的に給水されたり、鉢の底の水の腐敗等による病原菌の発生も考えられる。
又、給水弁を開閉する為の複雑な装置、及び設置場所が限定される欠点があった。
In the conventional water supply apparatus described above, even when the soil is moist, water is always supplied, water is forcibly supplied by a timer, or pathogenic bacteria are generated due to decay of water at the bottom of the pot.
In addition, there is a disadvantage that a complicated device for opening and closing the water supply valve and an installation place are limited.

本発明は以上の欠点を解消すべく、予め設定しておいた給水予定日が、大気の乾燥状態に応じて変化し、又、水の長期間の滞留による腐敗等も無く、複雑な装置も、専用の設置場所も必要とせず、植木鉢、プランタ−等に取り付けるだけで給水出来ることを目的とする。In the present invention, in order to eliminate the above drawbacks, the preset water supply scheduled date changes according to the dry state of the atmosphere, and there is no decay due to long-term retention of water. The purpose is that water can be supplied just by attaching it to a flower pot, a planter, etc. without requiring a dedicated installation place.

上記目的を達成するために本発明は、水を入れた容器に毛細管現象により水分を吸収、発散する役目の蒸発シ−トを取り付けた蒸発器と、その下部にある給水用の水を入れる給水容器が、蒸発器に設けたシャフトと、給水容器に設けた軸受けによって組み合わされ、大気の流入、遮断の役割をしている。In order to achieve the above object, the present invention provides an evaporator in which an evaporating sheet for absorbing and releasing moisture is attached to a container containing water by capillarity, and water for supplying water for supplying water under the evaporator. The container is combined by a shaft provided in the evaporator and a bearing provided in the water supply container, and plays a role of air inflow and shutoff.

又、蒸発器底部と給水容器上部にはお互いに反発し合う同極どうしの永久磁石が向かい合わせに固着してあり、その反発力により蒸発器が給水容器の上に浮上している。
蒸発器は蒸発シ−トからの水分の蒸発によって軽くなり、次第に上昇し、一定の高さになると、大気が軸受け側面にあけた穴からシャフトの先端の切欠き部分を通り給水容器に流入し、気圧がわずかに上昇することよって給水が始まり、逆に蒸発器に水を入れ水の重さで蒸発器が下降すると大気が遮断され、給水が停止する構造となっている。
In addition, permanent magnets of the same polarity repelling each other are fixed to face each other on the bottom of the evaporator and the top of the water supply container, and the evaporator floats on the water supply container by the repulsive force.
The evaporator is lightened by the evaporation of water from the evaporation sheet, and gradually rises to a certain height. When the air reaches a certain height, air flows into the water supply container through a notch at the end of the shaft through a hole in the side of the bearing. Water supply starts when the atmospheric pressure rises slightly, and conversely, when water is put into the evaporator and the evaporator is lowered by the weight of the water, the atmosphere is shut off and the water supply is stopped.

本発明の給水装置は電源等を必要としないため、電気による事故、故障、停電などによる動作不良を防止することが出来る。Since the water supply apparatus of the present invention does not require a power source or the like, it is possible to prevent malfunctions due to electrical accidents, breakdowns, power outages, and the like.

個々の植物の水分必要度に応じて蒸発器の水量を変えることによって給水予定日を変えることが出来る。The planned water supply date can be changed by changing the amount of water in the evaporator according to the water needs of individual plants.

又、大気の乾燥状態に応じて蒸発器の水分が蒸発するため、乾燥していれば設定給水日より早くなり、湿っていれば遅くなるため植物にとって最適な給水が行われ、旅行等によって家を留守にするときでも安心である。In addition, since the water in the evaporator evaporates according to the dry state of the atmosphere, the water supply will be earlier than the set water supply date if it is dry, and it will be slower if it is wet. It is safe even when you are away.

給水装置が蒸発器と一体化しており、かつ懸架式となっているためアタッチメント等に取り付ければ、特に設置場所が限定されることも無く、植木鉢やプランタ−等の上から給水することが可能である。Since the water supply device is integrated with the evaporator and is suspended, if it is attached to an attachment or the like, the installation location is not particularly limited, and it is possible to supply water from above a flower pot or planter. is there.

以下図面に示す発明を実施するための最良の形態により本発明を詳細に説明する。Hereinafter, the present invention will be described in detail by the best mode for carrying out the invention shown in the drawings.

図1、図2の本発明を実施するための第1の形態において、1は給水容器、2は蒸発器3は蒸発シ−トで蒸発器の支柱12に取り付けられている。In the first embodiment for carrying out the present invention shown in FIGS. 1 and 2, reference numeral 1 denotes a water supply container, 2 denotes an evaporator 3, and an evaporator sheet is attached to an evaporator column 12.

又、6は蒸発器に取り付けてあるシャフトで先端を切欠いてあり軸受け7に挿入されている。Reference numeral 6 denotes a shaft attached to the evaporator, the tip of which is notched and inserted into the bearing 7.

そして11は蒸発器を浮上させるための永久磁石で蒸発器と給水容器に同じ極が向かい合わせになるように固着されている。Reference numeral 11 denotes a permanent magnet for floating the evaporator, and is fixed to the evaporator and the water supply container so that the same poles face each other.

8は給水容器に水を補充するための着脱可能な給水口のキャップであり、9は給水量調節ネジで10の給水ノズルの水量を調節する。5は給水予定日目盛である。8 is a detachable water supply cap for replenishing water to the water supply container, and 9 is a water supply amount adjusting screw for adjusting the water amount of 10 water supply nozzles. 5 is the scale of the scheduled water supply date.

以下に上記構成の動作を説明する。水を入れた給水容器の軸受けに挿入された蒸発器のシャフトは、蒸発器に給水予定日迄水を入れると、水の重さで下降し、軸受け側面の穴に位置していたシャフトの切欠き部は、穴から離れ、軸受け側面の穴からシャフトの切欠き部を通り、給水容器内に流入する大気が遮断される。The operation of the above configuration will be described below. When the evaporator shaft inserted into the bearing of the water supply container containing water is poured into the evaporator until the scheduled water supply date, the evaporator shaft descends due to the weight of the water, and the shaft that was located in the hole on the side of the bearing is cut. The notch part is separated from the hole, passes through the notch part of the shaft from the hole on the side surface of the bearing, and blocks the atmosphere flowing into the water supply container.

この状態において、給水ノズル端面での圧力は給水容器内からの圧力として、大気圧と、水圧を合計したものとなる。一方給水容器外部からの圧力は大気圧と、表面張力を合計したものである。給水ノズルからは給水容器内の圧力が、給水容器外部からの圧力より小さい場合は水の滴下は起こらないが、大きい場合は水が滴下し、給水容器内の気圧がわずかに低下し、給水容器外部からの圧力と同じになった時点で停止し、安定状態となる。In this state, the pressure at the end surface of the water supply nozzle is the sum of the atmospheric pressure and the water pressure as the pressure from the inside of the water supply container. On the other hand, the pressure from the outside of the water supply container is the sum of the atmospheric pressure and the surface tension. When the pressure in the water supply container from the water supply nozzle is smaller than the pressure from the outside of the water supply container, water does not drip, but if it is large, water drops, and the air pressure in the water supply container drops slightly, and the water supply container When it becomes the same as the pressure from the outside, it stops and becomes stable.

この安定状態から、蒸発シ−トの毛細管現象によって吸い上げられた水が、大気の乾燥状態に応じて蒸発し、蒸発器が軽くなると次第に上昇し、蒸発器のシャフトの切欠き部が軸受け側面の穴迄来ると、穴から切欠き部を通り大気が給水容器内に流入し、給水容器内の気圧がわずかに大きくなる。したがって給水容器内の圧力が給水容器外部からの圧力よりわずかに大きくなった時点で、給水量調節ネジで設定しておいた水量が滴下し、給水が始まる。From this stable state, the water sucked up by the capillary action of the evaporation sheet evaporates according to the dry state of the atmosphere, and gradually rises as the evaporator becomes lighter. When coming to the hole, air flows into the water supply container from the hole through the notch, and the air pressure in the water supply container slightly increases. Therefore, when the pressure in the water supply container becomes slightly larger than the pressure from the outside of the water supply container, the amount of water set by the water supply amount adjusting screw is dropped and water supply is started.
