Description

Technical Field

[0001] The invention relates to the technical field of building closing devices, in particular to a honeycomb cut-off waveguide ventilation window. Background Art

[0002] In order to maintain air circulation inside the electromagnetic shielding room, windows need to be opened on the wall. The function of the waveguide ventilation window is to ensure air circulation while preventing the leakage of electromagnetic signals. The waveguide ventilation window is the main channel for shielding the exchange of indoor air with the outside world, and it can effectively cut off the passage of electromagnetic waves.

[0003] The waveguide ventilation window contains a honeycomb core. The principle is that these tiny holes allow air to circulate and achieve ventilation function. However, when electromagnetic waves try to pass through the honeycomb core, if the frequency of the electromagnetic waves is lower than the cutoff frequency of the waveguide, the waveguide will prevent the propagation of these electromagnetic waves and achieve electromagnetic shielding function. Due to its long-term contact with dust in the air, dust is easily attached to the honeycomb core and accumulated to form a blockage. The existing method usually adopts a detachable replacement method to periodically replace the waveguide ventilation window. Since the electromagnetic shielding room occupies a large space, the number of waveguide ventilation windows required to be installed will not be small.

The fan-shaped plate 8 overcomes the elastic force of the reset spring 9 and rotates in the direction of increasing the first space and reducing the second space. Negative pressure is generated in the first space, and the wind shield 12 in the air inlet channel 10 rotates to open and the wind shield 12 in the air outlet channel 11 is closed to absorb indoor gas. When the guide rod 19 enters the lower groove 21, the top rod 18 moves down and disengages from the fan groove 7 to cancel the push on the fan plate 8. The fan plate 8 is reset under the elastic force of the reset spring 9, squeezing the gas in the first space, and the wind shield 12 in the air inlet channel 10 is closed and the wind shield 12 in the air outlet channel 11 rotates to open, and the absorbed gas is quickly discharged. The exhausted gas is discharged from each second channel 33 of the fixed block 31 to the honeycomb core 2 to blow and clean the dust inside the honeycomb core 2; When the honeycomb core 2 is blown, the wind force is applied to the honeycomb core 2 , and the vibration springs 30 on the mounting rod 27 are also subjected to the wind force, so that the inner ring bodies 29 containing the honeycomb core 2 vibrate slightly at a high frequency to shake off the dust.
