Description

  The present invention relates to a feeder (hereinafter referred to as “water feeder”) that automatically supplies water, a wettable powder or the like (hereinafter referred to as “water”) to a flower pot, a planter, or the like.

In general, when water or the like is supplied to a plant planted in a flower pot or a planter, water or the like is applied to the upper opening of the pot from above with a joro or a jug.
There are many examples of growing flowers and vegetables on a concrete floor such as a veranda in an apartment. In plants with a large amount of transpiration from the foliage, the plants will die if they are not irrigated every day, such as on windy days, days when the air is dry, and periods of intense heat from early summer to autumn. If irrigated gently, the water in the pot may not be sufficiently distributed to the soil, and most of the water may come out from the bottom through a specific route in the pot.
Water supply that maintains a moist state for a certain period of time so that water is dripped slowly over time, water is sufficiently distributed to the soil in pots and planters, and water is sufficiently absorbed by plants over time. A vessel is required.

  Conventionally, as a method of supplying water to a flower pot or the like little by little from a water supply or the like (hereinafter referred to as “water supply”), a material that causes capillary action such as a water absorbing material is used as a water conduit, A method of supplying stored water etc. to the bottom or side of the pot, a method of placing a water tank above the flower pot and dripping water etc. through a material having a capillary phenomenon, or adding such material to the water A method of plunging into a water tank and sucking out water or the like to supply water has been proposed. In addition, as a method of directly irrigating, various methods such as a method of irrigating tap water etc. at a predetermined time using a timer, a method of dropping water from a small-diameter hole at the bottom of a container containing water, etc., and dropping it into a pot opening Has been proposed.

JP-A-10-52184 JP 2000-166405 A JP-A-9-94034 JP 2007-6712 A JP-A-8-37963 JP-A-8-37961 Actual climbing 3032552 JP 2010-35456 A

Each of these methods has challenges. There is no actual feeling of watering, the situation of water supply cannot be confirmed visually, and it is not convenient.
Also, the speed of water supply must be constant and stable.

  Regarding a method of supplying water using a capillary phenomenon using a capillary material such as a water absorbing material, If the height of the container containing water or the like is extremely lower than the bowl, water cannot move through the capillary material. 2. If the soil particles in the pot are coarse or have no aggregate structure or the like, the supplied water or the like may not spread throughout the pot. In soil composed of leaves, humus, etc., the supplied water does not reach the entire soil in the pot. 3. The roots may be soaked in water continuously for a long time and die without being noticed. During the hot summer season, the water temperature in the pot will be high, so you must be careful. 4). In the case of a dispersible drug solution such as a wettable powder, the contained solid content often cannot move in the capillary material, particularly in the direction against gravity.

And regarding the method of supplying water directly from the water tank as in Patent Document 8, when the water surface in the water tank is high, the difference in height between the water surface and the dripping port (the lower end of the “thin cylinder” in Patent Document 8), that is, Since the water pressure due to the water depth is greatly applied to the dripping port, the dripping amount per hour from the dripping port is very large, and the dripped water or the like may drain from the bottom of the bowl and waste water.
On the other hand, there is a problem that the amount of dripping per hour is extremely reduced when the water level in the water tank is lowered with time and the water pressure applied to the dripping port is reduced. It is desirable that the amount of dripping is constant at a constant amount of time until the water tank is full after the tank is full.

  We propose a water dispenser that supplies water by slowly dropping it in small amounts and with a constant drop amount. Moreover, the water feeder which can supply the liquid in which solid substances, such as a wettable powder, are dispersively mixed is proposed.

  In order to dripping slowly little by little, it is necessary to reduce the water pressure applied to the water supply port to reduce the amount of dripping from the water supply port per hour. In order to keep it constant, it is desirable that the water pressure applied to the water supply port does not fluctuate. In addition, it is desirable to be able to water with actual feeling and visual observation.

In order to solve the above problems, the present invention provides the following configurations. As illustrated in FIG.
A water tank part (hereinafter referred to as “reverse water tank part 1”) having a mouth (H) opened vertically downward and having a sealed upper part,
A holding unit 5 connected to the mouth (H) of the reverse water tank unit 1;
The tunnel part 2 connected to the holding part 5;
A regulating pond part 3 connected to the passage part 2 and having an open air mouth (B) above;
Consists of drainage holes 4 provided in the adjustment pond 3
The height of the floor (S) of the holding part 5 is below the lower edge (G) of the mouth (H) of the reverse water tank part 1;
In addition, the height of the lower edge (G) of the mouth (H) of the reverse water tank unit 1 and the ceiling of the tunnel part 2 on the side of the reverse water tank unit 1 from the highest part of the floor (F) of the tunnel part 2 The ceiling height of the lowest part of (C) is higher than the floor height of the highest part of the floor (F) of the passage 2;
And the floor height of the drainage port (D) of the drainage hole 4 is the lowest part of the height of the lower edge (G) of the mouth (H) of the reverse water tank 1 and the ceiling (C) of the passage 2. Lower than the ceiling height of the
It is a water supply device characterized by this.

  When the reverse water tank unit 1 is filled with water or the like for a while, the reverse water tank unit 1 has a mouth (H) at the bottom and upside down as a container, and the mouth (H) of the reverse water tank unit 1 is water of the holding unit 5 or the like. Since water is immersed in the water, negative pressure is generated in the water in the reverse water tank 1 and the reverse water tank 1 comes out from the lower mouth (H) after being deformed corresponding to the negative pressure as a container. I can't.

  However, the adjustment pond part 3 has an upper air outlet (B) above, and the drainage hole (D) provided in the drain hole part 4 falls and drains naturally, so that air enters and adjusts from the outer air outlet (B). The water surface in the pond part 3 falls. When the water level (L) in the adjustment pond part 3 becomes lower than the ceiling (C) of the tunnel part 2, air enters the tunnel part 2, and the water level (L) in the adjustment pond part 3 is the lowest in the tunnel part 2. Air enters the reverse water tank 1 when the height is lower than the ceiling height of the ceiling and lower than the lower edge (G) of the mouth (H) of the reverse water tank 1.

  Next, water having substantially the same volume as the amount of air that has entered the reverse water tank portion 1 flows out into the adjustment pond portion 3 through the mouth (H), the holding portion 5 and the passage portion 2, and as a result, the holding portion 5. Since there is no leakage of water from the tunnel 2 and the adjustment pond part 3 and their respective connection parts, the water level (L) in the adjustment pond part 3 rises and air starts to enter the reverse water tank part 1 Restored to the previous height. While repeating the intrusion of air and the flow of water, drainage is continued while maintaining the water level (L) in the adjustment pond 3 constant.

  The water level (L) in the adjustment pond 3 immediately after the air enters the reverse water tank 1 and the water moves from the reverse water tank 1, and the water level (L) in the adjustment pond 3 just before the air starts to enter. Therefore, the drainage rate at both time points is not substantially changed, and the drainage rate is constant and stable.

  Therefore, the floor of the drainage port (D) of the adjustment pond 3 and the height of the lower edge (G) of the mouth (H) of the reverse water tank 1 and the ceiling of the lowest part of the ceiling (C) of the passage 2 If the height difference with the height is set small, the difference between the floor height of the drainage port (D) and the water surface (L) water level in the regulating pond part 3 is also reduced, and as a result, the water pressure applied to the drainage port (D) is small. The drainage speed is also reduced.

  A hole with a diameter of approximately 0.5 mm is formed in the lower wall of the aquarium vessel having a wall thickness of approximately 0.3 mm, which allows free entry of air from above, in the direction of approximately 45 degrees above, When the amount of water dripping was measured, when the water surface was 94 mm above the dripping hole port, the water dripping rate was approximately 6.6 cubic mm per minute, and when the water level was 48 mm above, the dripping rate was It was about 3.5 cubic millimeters per minute, but when the water level falls and is above 21 millimeters, the dropping speed is about 1.3 cubic millimeters per minute, and when the water level is above 19 millimeters, the dropping speed is every minute. It was approximately 1.0 cubic millimeters. When the water level drops, the dripping rate decreases rapidly.

  Under the conditions of this experiment, 500 cubic millimeters of water will continue to drip for about 8.3 hours if the water level can be set to maintain approximately 19 millimeters above the drain. .

  If dripping irrigation takes time, it will surely reach the soil in the planter. Considering the soil condition in the pot and the weather conditions, etc., if you put a predetermined amount in the reverse water tank part, the water etc. will spread over the whole time, even if it is left as it is, it will automatically be in the reverse water tank. Water is supplied until there is no water.

  Depending on the conditions, in general plants even in the summer heat wave season, as a guide, 500 cubic millimeters in the water tank of the water supply set so that the water level is maintained above 19 millimeters in the morning. If water is added, it seems that the next 3 days will be enough to add water. In the meantime, the temperature of the bowl does not rise due to heat being removed by evaporation of the supplied water.

Air bubbles entering the reverse water tank rise. At that time, the water in the reverse water tank is stirred. Dispersed liquids such as wettable powders have the effect of becoming homogeneous.
In addition, since this water supply device does not use a capillary tube as a water conduit, it can also be used as a water supply device for supplying a wettable powder or the like in which solid substances are dispersedly mixed.

The end view showing the composition of this product. The end view of a water supply with a holding part provided with a screw mechanism. The end view of a water supply provided with a flexible passage. The end view of the water feeder which extended the drain pipe to the drain hole. The end view of the water feeder which attached the water absorbing material to the drain hole opening. The end view of a water supply which uses a holding part as a lid. A part of the holding part is shared as the wall of the adjustment pond.

There is also a need for a water supply device that can start water supply when the drying day is likely to continue, and can stop water supply when it rains or the weather changes suddenly.
Installed by comprehensively judging not only the soil conditions in the pot, but also the growth characteristics such as the transpiration rate of each plant, the characteristics of the installation location, the weather conditions, the physical properties of the liquid to be supplied, the weather around the day, etc. It is necessary for the person to decide the water supply speed appropriately. So far, there is no proposal that allows the installer to control the amount of water supplied per hour, that is, the water supply speed, in a simple water supply.

  Plants that are susceptible to root rot are supplied with water at a predetermined speed, and after a certain period of time, the water supply is stopped (hereinafter referred to as “off”), and then the plant waits for the pot to lightly dry. If you put water in the reverse water tank, you do not have to keep supplying water until it is empty. Until now, there is no proposal that the installer can start water supply as appropriate (hereinafter referred to as “on”) and can be turned off with a simple water supply device.

It is proposed that the holding part 5 is provided with a screw mechanism for holding the reverse water tank part 1 by connection using a screw mechanism. As shown in FIG. 2, the holding portion 5 has a screw groove (8), and is screwed in using the screw groove (8) while turning the reverse water tank portion 1 having a cylindrical mouth. It is possible to adjust the height difference between the height of the lower edge (G) of the mouth (H) of the reverse water tank unit 1 and the height of the floor of the drainage port (D). If the lower edge (G) of the mouth (H) of the reverse water tank 1 is lower than the ceiling (C) of the cross section of the passage, the difference in height between the two changes depending on the rotation angle of rotation. It leads to change. If the reverse water tank 1 is turned and screwed down, the drainage speed will be reduced, and if it is further turned below the floor level of the drainage port (D), the water supply will be stopped. If further screwed, the lower edge (G) of the mouth (H) hits the floor (S) of the holding part 5 as shown in FIG. This water supply can be used as a cover replacement.
Turning it in the reverse direction and turning it up above a certain height turns it on, and further lifting it increases the drainage speed. This is the same in terms of the effect of the drainage speed or the like even when the vertical movement is performed by a fitting mechanism or the like using sliding surfaces instead of the screw mechanism.

When the height of the lower edge (G) of the mouth (H) of the reverse water tank portion 1 is higher than the ceiling height of the lowest portion of the ceiling (C) of the passage portion 2, the lowest ceiling (C) of the passage portion 2 If the ceiling height of the part can be freely adjusted as shown in FIG. 3, the drainage speed can be changed.
Specifically, the connection between the reverse water tank unit 1 and the holding unit 5 and the holding unit 5 and the passage portion 2 is made airtight, the ceiling height of the passage portion 2 is lowered by the ceiling height adjusting means 9, and the floor of the drain outlet (D) If the height difference between the two is reduced and the height difference between the two is reduced, the drainage speed will be reduced. It turns off when the floor becomes lower than the floor of the drain (D).
If the floor height of the passage portion 2 is raised by the floor height adjusting means 10 above the ceiling height of the lowest portion of the ceiling (C) on the reverse water tank portion 1 side from the highest portion of the floor (F) of the passage portion 2, it is turned off. Become.
These controls can be operated at any time while the installer visually observes the dripping situation, and as a result, the water supply speed and on / off can be easily changed at any time. At the same time, it can be watered with subtle adjustment of the amount.

  Moreover, the location other than the bottom of the adjustment pond is good for the installation position of the drain hole 4. This is to prevent the inflow port of the drainage hole from being blocked even if foreign matters mixed in water or the like or large dispersed particles exceeding the standard sink due to the weight of the particles.

  Moreover, the installation angle of the drainage hole may be upwardly horizontal or higher as shown in FIG. 2, and the water in the adjustment pond may be discharged so as to be spouted. It is possible to prevent foreign matters mixed in water, etc. or large dispersed particles exceeding the standard from falling into the bottom of the gravity direction without being caught in the discharge flow near the drainage hole, and as a result not to block the inlet of the drainage hole. .

If the drain pipe 7 is joined to the tip of the drain hole 4, the tip of the drain pipe 7 becomes the drain port (D). If the floor height of the drainage port (D) is freely controlled, the degree of freedom is further increased in adjusting drainage speed and drainage on / off.
For example, as shown in FIG. 4, if the floor height of the drainage port (D) at the tip of the drainage pipe 7 is lifted by the drainage port height adjusting means 11, the amount of drainage will be reduced, and if it is further raised, the drainage port (H) The drainage can be turned off when the height of the lower edge (G) or the ceiling height of the lowest ceiling portion of the passage 2 is exceeded. Conversely, if it is lowered, the amount of drainage will increase. Since the water level in the adjustment pond 3 is always constant, fine adjustment is possible.

  On the other hand, if the cross section of the drainage port is made extremely small, the electrical action such as the viscosity of water and the surface tension of the water and the wall of the adjustment pond part is superior to the water pressure due to the difference in the water level in the setting with a small amount of drainage. , Water, etc. may not come out from the drain. In the previous experiment, when the water surface was lower than 15 mm, water did not come out from the drain.

  As countermeasures, as shown in FIG. 5, a water absorbing material 13 having a capillary action such as a water absorbing cloth is attached to the outside outlet of the drainage port (D), and the suction force of the water absorbing material 13 is assisted to adjust. It is recommended to draw water from the inside of the pond 3.

The draining speed is more than doubled by the two forces of extrusion by water pressure and suction by capillary action.
On the other hand, when the water level difference is large and the water pressure is high, the water absorbent 13 serves as a resistor against the flow of discharge and can be used to adjust the amount of drainage.

  The drainage speed from the drainage port can be adjusted by resistance to the flow of water or the like as an additional means other than the method of utilizing the water pressure control according to the basic configuration of the present invention. For example, changing the inner diameter of the drain hole, changing the drilling angle of the drain hole, changing the drain hole length or drain pipe length, adding resistance to the flow of water or the intrusion of air into the drain hole or passage There is a method to adjust the air intrusion speed by setting the outside air mouth of the adjustment pond part to be extremely small or masking, etc., depending on the purpose of use of the water supply, the physical characteristics of the liquid to be supplied, and the use conditions Can be combined and changed as appropriate.

  The holding part 5, the passage part 2, the adjustment pond part 3, the drain hole part 4 or the reverse water tank part 1 are continuous with respect to the flow of water and can be integrated. Moreover, as shown in FIG. 2, it can be vertically inserted into the soil 12 or the like of the pot under the reverse water tank part 1 or the holding part 5 or the passage part 2 or the adjustment pond part 3 or the drainage hole part 4. If the self-supporting member 6 such as a bar-shaped piece or the pushing handle 14 is joined, the water supply can be easily set in a pot, a planter, or the like at an arbitrary angle.

In order to fill the reverse water tank unit 1 with water or the like, the reverse water tank unit 1 needs to be detachable from the first holding unit 5. What is necessary is just to make the joining part of the said reverse water tank part 1 and the previous term holding | maintenance part 5 into a screw mechanism, a fitting mechanism, etc.
Furthermore, this water feeder can also be used by attaching various commercially available containers as a reverse water tank section.

  This water supply can also be used when supplying emulsion liquid and flowable liquid. This water supply can also be used when supplying water to flower pots, planters, etc., and mixing insecticide / bactericide solution, etc. over time in a tank, pond, paddy rice field, etc.

  In addition, regarding the reverse water tank part 1, there may be a lid on the upper side. Combined with air intrusion from the connecting part of the reverse water tank part 1 and the holding part 5 or the holding part 5 and the passage part 2, the air more than the volume such as water drained from the drainage port (D) of the adjustment pond part 3 If the water does not enter the reverse water tank section 1, there is no problem in the intended effect of the present invention.
