The invention discloses a deodorization device for a gutter inlet, and relates to the technical field of drainage systems. The deodorization device comprises an umbrella-shaped deodorization stoppingcloth, an umbrella
handle, a connecting device and a control device used for shrinking and opening the deodorization stopping cloth, and the control device comprises an air cylinder and a
humidity sensor; when it rains and the
humidity sensor senses that the
humidity of the deodorization stopping cloth is equal to or higher than a rated value, a
signal is sent to the air cylinder, the air cylinderis started, so that a
piston rod drives a lower disc to move downwards along the umbrella
handle, and thus the purpose of shrinking the deodorization stopping cloth for drainage is achieved; when itstops raining and the humidity sensor senses that the humidity of the deodorization stopping cloth is lower than the rated value, a
signal is transmitted to the air cylinder, the air cylinder is started, so that the
piston rod drives the lower disc to move upwards along the umbrella
handle, and thus the purpose of opening the deodorization stopping cloth for stopping
odor is achieved. By means ofthe deodorization device for the gutter inlet, on the condition that smooth drainage of rainwater is guaranteed, the
diffusion of peculiar smell is stopped, and the
living environment of cities is improved.
