Abstract

The invention discloses a fresh air machine with a filter screen being convenient to renew. The fresh air machine comprises a shell body, a fan, an unwinding device, a winding device and the filter screen. An air inlet communicating with the outside world and an air outlet communicating with indoor space are formed in the shell body; the fan is arranged in the shell body and used for blowing the air in the outside world into the indoor space; the unwinding device and the winding device both are movably arranged on the shell body; the filter screen is arranged in a tensioning mode, one end of the filter screen is wound on the unwinding device, and the other end, between the unwinding device and the winding device, of the filter screen is connected with the winding device; and a filter part which can shield the air inlet or the air outlet is formed in the position, between the unwinding device and the winding device, of the filter screen. By matched using of the unwinding device and the winding device, the filtering part, used for shielding the air inlet or the air outlet, of the filter screen of the fresh air machine of the structure can be renewed without the need of replacing the whole filter screen, so that the efficiency of renewing the filter part is improved, and the replacing time of the whole filter screen is prolonged.
