incubator

Abstract

This application relates to the field of biological culture equipment technology, and discloses an incubator comprising: an inner liner, a circulating fan, a sealing support, and a negative pressure balancing device. The circulating fan includes a motor disposed outside the inner liner and fan blades disposed inside the inner liner. The motor is driven by the fan blades via a rotating shaft passing through the inner liner. The sealing support includes a support body and a support cover. The support body is fixed to the outer wall of the inner liner, and the support cover is fitted to the support body to form a mounting cavity for enclosing the motor. The negative pressure balancing device is disposed at the axial hole gap between the fan blades and the inner wall of the inner liner. The negative pressure balancing device includes an airflow induction structure that moves synchronously with the rotating shaft to generate a reverse airflow to counteract the negative pressure at the axial hole gap. This design effectively solves the problem of contaminant intrusion caused by the inability to completely seal the rotating shaft hole of a long-shaft fan, ensuring a high level of cleanliness inside the incubator and thus reducing the risk of contamination of cultured samples.
