The invention provides an indoor planter using a fan for accelerating air flowing. The indoor planter comprises a container body, wherein the container body is provided with a
container port and a containing chamber, and a
liquid storage holder is arranged below the containing chamber; the container body comprises an inner
barrel and an outer
barrel arranged outside the inner
barrel in a sleeving mode; the sidewall of the inner barrel is at least composed of two
layers of walls, a filter cavity is formed between the two adjacent walls, a plurality of air inlet holes are formed in each layer of wall, an air flowing channel is formed between the sidewall of the outer barrel and the sidewall of the inner barrel, and a flowing
channel inlet is formed in the bottom of the air flowing channel; and an electric fan is installed beside the container body, air is blown into the air flowing channel from the flowing
channel inlet by virtue of the electric fan or air in the air flowing channel is extracted away from the flowing
channel inlet by virtue of the electric fan to form a
positive pressure or a negative pressure in the air flowing channel, so that air flows directionally from the air inlet holes, the filter cavity, the containing chamber and the
container port. The indoor planter greatly accelerates ventilation for the roots of plants planted by the planter, greatly improves the air permeability of soil, and enables the roots of the plants to grow with a full load; and the
air purification capacity is eight times that of a common planter.
