Description

  The present invention relates to an automatic water supply planter for cultivating plants such as flowers, foliage plants, vegetables and beans.

Conventional technology

  Water supply is necessary for plant cultivation, but this takes time, and knowledge is necessary to provide an appropriate amount of water.

  Therefore, many proposals have been made for so-called automatic watering plant pots or pots that automatically supply water. However, it does not require time and effort, and the manufacturing cost is low, so that it can be used especially for rooftop greening. There are few proposals of planters.

  For example, Japanese Patent Application Laid-Open No. 2004-81167 states that “a water supply of an appropriate amount according to a plant body and weather can be easily performed without watering in summer or absence, As a container that can promote the growth of plants without worry, it has a plant cultivation part (1b) and a water supply part (1a) that functions as a receiving part of the water supply tank (2) or as a water supply tank. A communication channel (10) is formed between the water supply unit (1a) and the plant cultivation unit (1b), and the balance between atmospheric pressure and water pressure is utilized from the water supply unit (1a) to the plant cultivation unit (1b). The plant cultivation part (1b) has a structure in which water is supplied to a constant water level, the medium (4) in the upper layer (3), the medium in the upper layer (4), the liquid reservoir in the lower layer (5) An air layer is present, and at least a portion is provided between the culture medium and the air layer. To have breathable, water-absorbent structure in a manner in contact with both the medium and the liquid reservoir (8) at least partially installed bottom water type culture vessel comprising "it is introduced.

Japanese Patent Laid-Open No. 2005-40009 states that “It is possible to supply water without wasting water by using a simple method, which is usually done with showers, rain dew, etc. in potted water supply. As a pot set with a structure that can be adapted to the water supply of all plants, the pot body 1 is provided with an external connection port 5 for water supply, so that the water supply tank 3 can be easily detached. Depending on the liquid level, the water in the pot is generally absorbed by the self-osmotic action of the soil, and only the amount of water consumed by the plant and reduced by evaporation is replenished. Also, by adding an auxiliary tank 10 such as a plastic bottle to the water supply tank 3, the amount of makeup water can be increased and the liquid level of the water supply tank 3 can be kept constant. Set height can be adjusted to parts By adding the structure, water supply tank 3 of liquid surface level can be changed, water supply equipment of the contents of the water absorption of the soil can be adjusted "has been introduced.
