The baffle plate 5 will be against the outer wall of the second side plate 3 under the action of the spring. At this time, it is convenient to remove the installation frame 4 from the window 301, which is convenient to assemble and disassemble, reliable to fix, and can improve the cleaning efficiency of the dustproof net 401.
