Abstract

Because the utility model adopts the multi-hole material structure with a lower infiltration ability than the soil at the bottom, the utility model provides a tool which can utilize the current flowerpot and can supply water or nutrition liquid to the plants or flowers in the flowerpot on demand and quota for a long period without man power; the multi-hole material with different penetrability is selected according to the growth feature of different plants or flowers and can make the plants or flowers under the best growth status for a long period; the utility model is used to irrigate the trees in the drought and half drought area.

Description

A kind of automatic water-supplying device

The utility model belongs to gardens, particularly gives the apparatus of plant quantitative water supply.

Pot plant must be according to the timing of needed water of plant or nutrient solution, the needs that weight feed could satisfy plant growing.For the individual of family-raise pot plant or flowers, to such an extent as to owing to the growth characteristics of supporting pot plant or flowers are had little understanding or owing to reasons such as work usually negligence of management cause its undergrowth dead; And quantity, plant or the flower growth of increasing work efficiency, reduce production costs, reducing a staff for gardens enterprise or department more luxuriant be the target of its pursuit; The method of dealing with problems is satisfied the demand with regard to providing a kind of apparatus that can replace the people that water or nutrient solution are supplied with pot plant or flowers for a long time, as required, according to quantity.Patent Office of the People's Republic of China has announced a kind of name on September 23rd, 1992 and has been called " can regulate the flowerpot automatic water-supplying device " (application number: utility model patent 92202071.X) has successfully solved this problem; Its principle is to utilize capillarity, plant or the flowers root of automatic water-supplying device in flowerpot is housed in the bottom of existing flowerpot waters or nutrient solution is provided; In actual use, the center of gravity of flowerpot and plant or flowers is raise, when occupying more confined spaces, increased lability so again owing to increased an automatic water-supplying device in the bottom of existing flowerpot.Therefore need a kind of more simple and practically, both utilized existing flowerpot, do not increase height again, apparatus that can also automatic water-supply solves to pot plant or flowers and waters for a long time or the problem of nutrient solution is provided.

Goal of the invention of the present utility model just provides a kind of atmospheric pressure that utilizes directly to the automatic water-supplying device of pot plant or flowers root transporting water or nutrient solution.

For reaching this purpose, inventive concept of the present utility model is the bottom to be had in the container of porous mass water or nutrient solution are housed, and facing down of soil directly is inserted into the root of pot plant or flowers from flowerpot; Wherein the infiltration capacity of the porous mass that is adopted is lower than the infiltration capacity of soil, its objective is the seepage velocity that is used to slow down water or nutrient solution; Under the effect of atmospheric pressure, water in the container or nutrient solution are penetrated into the root of pot plant or flowers continuously, lentamente, satisfy the needs of pot plant or flower growth, thereby have realized goal of the invention of the present utility model.

In order to realize inventive concept of the present utility model, container cartridge that the utility model is opened by two (1) and the lower end cap (3) that is contained in the mouth of its underpart are formed.Wherein, the material of lower end cap (3) is a porous mass, and the permeability of porous mass is lower than the permeability of soil.In use, on the automatic water-supplying device of water or nutrient solution lower end cap (3) is housed with being marked with one side be inserted into plant or flowers root in the flowerpot, another side then exposes soil; Water or nutrient solution are penetrated in the soil through lower end cap (3) under the action of air pressure at an upper portion thereof like this, and by the permeability decision water of lower end cap (3) material or the seepage velocity of nutrient solution, according to the growth characteristics of different plants or flowers select to have different permeability can porous mass, just can make plant in the flowerpot or flowers be in the growth conditions of the best; Therefore just finished inventive concept of the present utility model.

Because the utility model has adopted in the bottom structure that infiltration capacity is lower than the porous mass of soil is housed, and a kind of existing flowerpot that utilizes is provided, replace the people water or nutrient solution to be supplied with for a long time, as required, according to quantity the apparatus of pot plant or flowers; According to the growth characteristics of different plants or flowers select to have different permeability can porous mass, can make plant or flowers be in best growth conditions for a long time; Owing to need not water for a long time, also just reduced the number of times that waters, saved the labour, save spending, thereby improved benefit.The utility model also is specially adapted to watering of arid, semiarid zone trees.

P-water or nutrient solution upper air pressure

In order to reduce the evaporation that is contained in water in the utility model or nutrient solution, the utility model also is equipped with the upper plug head (2) that has ventilation hole (3) on the top of container cartridge (1).When ventilation hole (3) hole less, and during upper plug head (2) broad, just formed elongated hole (damping hole), at this moment water or nutrient solution upper air pressure p are lower than external atmospheric pressure in the utility model, thereby the seepage velocity of water or nutrient solution is reduced, therefore under the situation of the material of not changing lower end cap (3), realized equally regulating the purpose of water or nutrient solution permeable speed, and be a simple and practical way.

Claims

1. an automatic water-supplying device is made up of container cartridge (1), lower end cap (3), and it is characterized in that: container cartridge (1) two is open-minded, and lower end cap (3) is contained in the lower ports of container cartridge (1).

2. by the described automatic water-supplying device of claim 1, it is characterized in that: the material of lower end cap (3) is a porous mass, and the permeability of porous mass is lower than the permeability of soil.

3. by the described automatic water-supplying device of claim 1, it is characterized in that: the upper plug head (2) that has ventilation hole (3) also is housed on the top of container cartridge (1).

4. by the described automatic water-supplying device of claim 1, it is characterized in that: ventilation hole (3) is an elongated hole.
