Degradable plastic flowerpot

Abstract

The invention provides a degradable plastic flowerpot. A third inserting ring at the bottom of an inner container of the flowerpot is inserted into a first annular inserting groove and connected with a bearing base in a clamped mode. On one hand, the flowerpot shell is arranged on the flowerpot inner container in a sleeving mode, and on the other hand, the flowerpot shell is inserted into the second annular inserting groove and connected with the bearing base in a clamped mode. The fixing rod is inserted into the first through hole, the second through hole, the third through hole, the fourth through hole and the fifth through hole to connect the flowerpot inner container, the flowerpot shell and the bearing base together. Flowers are contained in the flowerpot inner container, the flowerpot inner container is watered, and if the watering amount is too large, water can enter the space between the flowerpot shell and the flowerpot inner container through the water leakage holes, so that the flowers can absorb the water slowly. If the watering amount is larger than the preset value, excessive water is discharged to the outside by opening the water escape valve. The bearing base, the flowerpot inner container and the flowerpot shell which are made of degradable plastic are good in flexibility, excellent in impact performance and high in structural strength, and the requirement for durability is met.
