Bowl Vent
remove odor closest to the source

Usually a bathroom vent is placed on a wall near the ceiling, allowing odor originating from the toilet bowl to travel all over the room before being sucked out. This alternative location puts the vent within the bowl, preventing odors from escaping the bowl during pooping, thus dramatically reducing the amount of odor one must endure.

If the fan has enough power to accidentally suck in bowl water like a straw, the tunnel can have another mouth away from the water bowl to prevent air pressure from decreasing to that point. The vent fan will also be placed above the bowl's maximum water level.
