The invention provides an intelligent garbage can. The intelligent garbage can comprises a shell, a pressure sensor, a fixed part, a garbage bag and an alarm, wherein a first containing cavity is limited in the shell, and a first opening is formed in the first containing cavity; the pressure sensor is arranged on the inner wall surface of the shell; the fixed part is arranged around the first opening; a second containing cavity is limited in the garbage bag, a second opening is formed in the second containing cavity, one end, which is close to the second opening, of the garbage bag is connected with the fixed part, and a bag body of the garbage bag is opposite to the pressure sensor; and the alarm is connected with the pressure sensor so as to send an alarm message when the pressure is greater than a preset pressure value. The intelligent garbage can has the advantages of the simple structure, low cost and convenience in use, and the structure that the shell, the pressure sensor, the fixed part, the garbage bag and the alarm are combined is used, so that the intelligent garbage can is automatically reminded to replace the garbage bag when the garbage bag is filled to a certain extent.
