The invention discloses an air exchanger. The air exchanger comprises an exhaust pipe with an upper end and a lower end; a tubular body with an upper end and a lower end. The upper end of the tubular body is connected with the lower end of the exhaust pipe. An air chamber is equipped inside the perine of the tubular body. The air chamber comprises an air supply port for supplying air to the air chamber and an an air spray channel applied for spraying the air inside the air chamber to the inner side of the tubular body so as to make the air move from the lower end of the tubular body to the upper end of the tubular body inside the tubular body. According to the air exchanger in the invention embodiment, air is sprayed through the spray channel to generate rapid air flow. Then local negative pressure is generated around the lower end of the tubular body to drive the peripheral air to enter the air exchanger and then be discharged. Therefore, the air exchange efficiency of the air exchanger is improved. Better air exchange effects are then achieved. |
