Description

Plant planter

Technical Field

The invention belongs to the technical field of planting, and relates to a plant planter, in particular to an intelligent control type plant planter.

Background

Along with the improvement of living standard, people are pursuing mental satisfaction in addition to pursuing matters, and gardening planting can save people from complicated work and life. However, the conventional soil cultivation method is difficult to realize and popularize in crowded cities, and needs to have certain expertise and time and energy for planting, and the result is affected by the influence of external environment in the planting process, so that consumers are afraid of the planting. Accordingly, home plant planters have been developed.

For example, a domestic plant cultivation device [ authorized bulletin number CN205124503U ] for preventing blockage appears in the market, which comprises a barrel body for containing a culture solution, a plant planting unit is arranged at the top of the barrel body, an irrigation unit for conveying the culture solution to the plant planting unit is arranged in the barrel body, the irrigation unit comprises a water pump arranged in the barrel body and a conveying pipe connected with the water pump, and a filter plate for separating the water pump from the upper space of the barrel body is arranged in the barrel body. The filter plate is arranged in the barrel body to separate the water pump from the upper layer space of the barrel body, so that the water pump is prevented from being blocked by the culture medium and plant stubbles falling from the plant planting unit when the culture medium and the plant stubbles are sucked into the water pump, and the cleaning and maintenance cost is reduced.

However, the cultivation devices cannot be overlapped, and a plurality of cultivation devices need to be tiled when batch planting is performed, so that the problems of large occupied area and inconvenient management are caused. After long-time use, the water culture solution in the cultivation device is gradually reduced due to evaporation and plant absorption, if the water culture solution is not timely added into the cultivation device, the plant is exhausted due to the fact that nutrients are not obtained, the cultivation device adopts manual water culture solution adding, the automation degree is low, and the plant exhaustion is easier to cause due to reasons of forgetting, non-timing and the like. The cultivation device is not provided with an oxygen supply device, and in some places with thin oxygen, plants can not obtain the needed oxygen, so that the problems of growth stopping, dead and the like occur, and the survival rate is low. In a word, this cultivation device only needs to guarantee the survival rate of plant under the careful care of people, extravagant energy and time.
