Don''t feel the same / Toiletries

Don''t feel the same

When people use the regular closestool, the toilet water inside would rebound on them under external force, thus a modification design cross my mind.
Introduction: Closestool remains closed in normal situation. When people open the closestool lid, the shake area on it will drive the pressure tank to provide vacuum, which will reduce the pressure to make water flow backward, so that people can rest assured in using it.
