Abstract

The invention provides a wireless optical frequency demodulator with an anti-interference structure, relates to the technical field of optical frequency demodulators, and solves the problems that according to an existing optical frequency demodulator, dust accumulation can cause blockage or electrostatic influence on normal work of a device, and in a humid environment, excessive moisture enters the interior of the device, so short circuit of elements in the device is liable to be caused. The optical frequency demodulator comprises a shell, a guide groove is formed in the shell and used for assembling a guide block, an air bellow is further fixedly connected to the left side of the shell, and fans are installed in the air bellow in a linear array mode; an air outlet is further formed in the left side of the interior of the shell, the air outlet is matched with the air inlet, the air bellow is communicated with the air outlet, a cover plate is slidably connected to the top end of the shell, moisture contained in air flow is filtered through a moisture-proof pad inserted into the inner side of the cover plate, and then the air flow enters the interior of the shell to be subjected to dust removal operation; and then the air is discharged through an air overflow opening formed in the right side of the shell.

Description

technical field [0001] The invention belongs to the technical field of optical frequency demodulators, and more specifically relates to a wireless optical frequency demodulator with an anti-interference structure. Background technique [0002] Optical frequency demodulator, also known as single-port optical transceiver, is a three-piece set of optical fiber transmission equipment developed for special user environments. [0003] The existing optical frequency demodulator still has the following deficiencies: [0004] 1. Most of them are placed on the desktop and placed against the wall, so that the outside of the device will cover a large amount of dust over time, and the accumulation of dust will cause blockage or static electricity to the normal operation of the device, and too much dust in a humid environment Moisture entering the interior of the device can easily cause a short circuit in the original components inside the device. [0005] 2. The terminal is set on the ...
