Description

Technical Field

[0001] The utility model relates to the technical field of ventilation devices, and more specifically, to a ventilation device. Background Art

[0002] In the prior art, in existing ventilation devices, there may be a lack of a component specifically used to release the fixed filter, which may make it difficult for operators to quickly and safely disconnect the filter from the ventilation device when maintaining or replacing the filter. This situation is particularly inconvenient in ventilation devices that require regular inspection or replacement of the filter, because each operation requires additional time and effort to handle the fixing and releasing of the filter.

[0003] On the other hand, existing ventilation devices may lack an effective component to fix the filter, which may cause the filter to be not firmly positioned in the ventilation device and easily loosen or fall off, thereby affecting the filtering effect and normal operation of the ventilation device. This problem is particularly obvious under long-term use or harsh environmental conditions, because the instability of the filter may reduce the filtering effect of the ventilation device and increase maintenance frequency and cost.

[0004] Existing ventilation devices may lack a component specifically used for ventilation, which may result in the ventilation device being unable to effectively inhale fresh air and expel indoor dirty air, thereby affecting indoor air quality and ventilation effects. This problem is particularly critical in places where efficient ventilation is required, such as hospitals, laboratories, factories, etc., because the inadequacy of ventilation devices may affect the health and comfort of the indoor environment.
