Problems solved by technology

As mentioned above, the ventilating fan housing 93 is usually installed at a high level position such as the ceiling, so users still face the problem that it is difficult to remove the filter member 92
[0005] In summary, the existing ventilation fan 9 must be completely removed from the ventilation fan cover 91 in actual use before the filter member 92 can be removed, and the filter member 92 is difficult to be removed from the ventilation fan housing 93, resulting in The existing ventilating fan 9 has the problem of poor usability, and it is urgent to provide a further improved ventilating fan to improve its usability

Description

technical field [0001] The invention relates to a ventilating fan, in particular to a ventilating fan provided with a filter screen. Background technique [0002] Please refer to figure 1 Shown, is a kind of existing ventilation fan 9, comprises a ventilation fan cover 91, a filter element 92 and a ventilation fan casing 93. The ventilation fan cover 91 includes a frame body 911 and a cover plate 912, the frame body 911 and the filter member 92 are combined in the ventilation fan housing 93, and the filter member 92 is formed between the ventilation fan cover 91 and the ventilation fan housing 93 space, so that the airflow can pass through the filter element 92. Thereby, the filter member 92 can filter the airflow flowing from the ventilator cover 91 to the ventilator case 93 . [0003] Since the filter element 92 is combined with the ventilation fan housing 93, when the user wants to remove the filter element 92 for cleaning or replacement, the frame body 911 and the cov...
