[0002] Filtering is the operation of filtering out specific frequency bands in a signal. It is an important measure to suppress and prevent interference. Filtering is divided into classical filtering and modern filtering. A filter is an engineering application circuit designed based on the influence of circuit parameters on the circuit bandwidth.

[0003] When the filter device is in use, it is usually installed in a filter power cabinet. However, the existing filter power cabinet has poor internal heat dissipation effect. Therefore, some people think of setting the heat dissipation port to a structure that can be opened and closed automatically to improve the heat dissipation effect. For example, the Chinese utility model patent with announcement number CN216873588U specifically discloses a filter power cabinet.

[0004] However, in actual use of the above-mentioned filter power cabinet, people will find that when the sealing plate is opened, since there are no protective measures at the vents, it is easy for external dust to enter the cabinet. Over time, dust will accumulate in the power cabinet, affecting the internal heat dissipation effect. Utility Model Content
