Technical Field

The invention belongs to the field of daily life, and relates to an unpowered maintenance-free automatic irrigation technology for potted plants.

Background

At present, most automatic irrigation technologies adopt an electronic automatic irrigation technology, are controlled and adjusted by a single chip microcomputer, are sensed and monitored by a humidity sensor, and are supplied by storage batteries, solar energy and the like. The device has higher automation degree, but the corresponding circuit board has complex structure, high failure rate and higher requirement on electricity storage capacity, and is difficult to ensure long-term continuous automatic irrigation. For example, chinese utility model patent with publication number CN103503721A discloses "an automatic flower watering flowerpot", which utilizes a water pump and a solenoid valve to spray water in the form of water column, and water drops are easy to spill, possibly causing circuit corrosion, and does not consider the long-term power supply problem, and the device can only realize one-to-one watering, and is difficult to satisfy the requirement of watering multiple plants in a pot at the same time. The chinese utility model patent with publication number CN108575705A discloses an automatic flower watering device, which uses solar energy for power supply, is energy-saving and environment-friendly, but cannot solve the problem of power supply in continuous cloudy days or rainy days. The chinese utility model patent with publication number CN108112461A discloses an automatic flower watering device, which has a water tank with too high position, insufficient water storage capacity, high economic cost and difficulty in meeting the long-term working requirement.

The domestic market demand for automatic plant watering devices is increasing, and the siphon principle can realize unpowered automatic water supply and is adopted in some invention patents. For example, chinese utility model patent publication No. CN204119867U discloses an automatic watering flowerpot which adopts an inverted siphon to discharge water, and embeds one end of a suction pipe into the flowerpot, simply realizing automatic watering. Technically, the design and research of the capillary action of the automatic irrigation device based on the bionic principle are relatively few, the research on the capillary action mainly comprises the comparative investigation on the capillary action of different materials, the capillary action effect of the different materials is mainly determined by capillary pressure, but the application of the automatic irrigation device is not expanded, and the capillary action is not widely researched in the automatic irrigation scope.

use cultivation district is the center, and the water storage district is located cultivation district all around, and the water storage district is located cultivation district below, separates by the baffle that sets up specific pore, and capillary material is tiled in cultivation district bottom and is extended to the water storage district through the pore canal, and the water filling port is established at the water storage district top, and inlet channel, exhaust passage are established to the bottom.

The size of the cultivation area is divided into three types, large, medium and small, according to the size of the plant, and is large: the caliber is 34-36 cm, and the height is 22-24 cm; the method comprises the following steps: the caliber is 22-24 cm, and the height is 16-18 cm; small: the caliber is 16-18 cm, and the height is 11-13 cm.

The size of the water storage area is as follows: the inner diameter and the height of the cultivation area are equal to the caliber and the height of the cultivation area, and the outer diameter is 5-10 cm larger than the inner diameter.

The size of the impoundment area is: the diameter is the same as that of the cultivation area, and the height is divided into three types according to the water demand of plants, wherein the height is 5-6 cm, the middle is 9-10 cm, and the height is 13-14 cm.

The capillary material is made of wood pulp fiber sponge, one end of the capillary material is flatly paved at the bottom of the cultivation area, the other end of the capillary material is hung to the bottom of the water storage area, and the contact surface of the capillary material and soil accounts for 40% -60% of the soil area according to different water requirements of plants.

The invention is further illustrated with reference to the following figures and examples.

FIG. 1 is a schematic view of the present invention;

in figure 1, a water storage area 2, a cultivation area 3, a water inlet channel plug 4, a water inlet channel 5, a water storage area 6, a water filling port 7, an exhaust channel plug 8, an exhaust channel 9 and a capillary material

Detailed Description

When in use, the method comprises the following steps: (1) completely closing the water inlet passage and the air outlet passage by using the water inlet passage plug and the air outlet passage plug; (2) opening a water filling port to fill water into the water storage area until the water storage area is full, stopping filling water and closing the water filling port, wherein the water storage area is in a sealed state and is not influenced by atmospheric pressure; (3) adding water into the water storage area through the holes of the partition plates between the water storage area and the cultivation area until the water storage area is full of water, stopping adding water, and installing a capillary material; (4) the water inlet channel plug and the exhaust channel plug are pulled to the channel openings but not pulled out, so that the water inlet channel and the exhaust channel are ensured to be unblocked; (5) under the capillary action, water in the water storage area is continuously lifted to the bottom of soil in the cultivation area through the capillary material to irrigate the roots of the green plants, so that the water level in the water storage area is slowly reduced; (6) because the capillary material is communicated with the water storage area and the atmosphere, the atmosphere acts on the water storage area, and the water storage area is sealed in a low-pressure environment, so that a certain air pressure difference is formed between the water storage area and the water storage area. When the water level is lower than the exhaust channel opening, air enters the water storage area through the exhaust channel under the action of air pressure difference, the pressure at the upper part of the water storage area is gradually increased, and water in the water storage area is pushed to flow to the water storage area through the water inlet channel, so that the water level in the water storage area is raised; (7) when the water level is higher than the exhaust passage, the air intake is stopped, and then the water in the water storage area is prevented from flowing out, so that the water in the water storage area is slowly flowed out, and the automatic watering can be continued for more than several months as long as the water storage area stores enough water.

Siphon principle and capillary action are used for drawing the water in water storage area to the cultivation district, and after the liquid level in water storage area was less than the exhaust and passes through, under the effect of pressure difference, the air got into the water storage area, and increase water storage area upper portion pressure, and then promoted the water in the water storage area and got into the water storage area, until water storage area liquid level is higher than exhaust passage, exhaust passage closed this moment, and water storage area upper portion forms low pressure space once more. From this time, the automatic irrigation is completed.
