Abstract

The invention relates to an air exchange fan. The air exchange fan comprises a fan, an outer cover component and a filter screen, wherein the fan is provided with an air inlet and an air outlet; the outer cover component is arranged at the air inlet; the outer cover component comprises a body and a cover body; the body comprises an opening and a plurality of fixed parts; the opening is arranged corresponding to the air inlet; two oppositely arranged sliding chutes are adjacently formed in the periphery of the opening; the fixed parts are arranged on the body; the cover body and the body are arranged at an interval to form a gap; the cover body is provided with a plurality of connecting parts correspondingly connected to the fixed parts respectively; the filter screen is separably arranged on the sliding chutes in a sliding mode and is mounted on the opening; the size of the cover body is greater than that of the opening; Airflow flows to the filter screen and the air inlet through the gap, and is exhausted out of the air outlet through the fan.

Description

technical field [0001] The invention relates to a ventilation fan. Background technique [0002] With the gradual development of science and technology, people pay more and more attention to the quality of life, and the quality of air quality is closely related to people's health. However, in order to reduce noise, insulate heat, and prevent cold air from leaking out, buildings today often use special building materials to form indoor airtight spaces, so the ventilation is insufficient, making it impossible to remove harmful pollutants. [0003] Therefore, how to provide a kind of ventilating fan that can make indoor ventilation has become one of important issues. Contents of the invention [0004] In view of the above-mentioned problems, an object of the present invention is to provide a ventilating fan capable of keeping a room ventilated. [0005] To achieve the above purpose, a ventilating fan according to the present invention includes a fan, an outer cover assembly...
