The invention relates to a noise reduction method of a vacuum excrement collecting system and the vacuum excrement collecting system. A middle box is installed between a dirt collecting container and a toilet stool, the dirt collecting container is connected with a vacuum generating device, and a vent valve selectively communicated with the atmosphere is installed on the middle box; in an urinating state, the low vacuum degree is controlled to be built in the middle box, and dirt in the toilet stool is sucked into the middle box in the low vacuum state, or the middle box is controlled to be in a normal pressure state, and the dirt in the toilet stool flows into the middle box through gravity; in a defecation state, the high vacuum degree is controlled to be built in the middle box, and dirt in the toilet stool is sucked into the middle box in the high vacuum state; and the middle box after dirt collection is sucked into the dirt collecting container in a vacuum state. Two-stage vacuum control is formed between the toilet stool and the dirt collecting container, the middle box is controlled to be switched among a normal-pressure state, a low-vacuum state and a high-vacuum state during dirt suction according to the defecation state, and a noise generated by vacuum breaking during dirt discharge of the toilet stool is effectively reduced.
本发明涉及一种真空集便系统降噪方法及真空集便系统,在污物收集容器与便器之间安装一中间箱,将污物收集容器与真空发生装置连接,在中间箱上安装有可选择性地与大气连通的通气阀;小便状态时,控制在中间箱内建立低真空度,便器内的污物在低真空状态下吸入中间箱,或控制中间箱为常压状态,便器内的污物依重力流入中间箱内;大便状态时,控制在中间箱内建立高真空度,便器内的污物在高真空状态下吸入中间箱;收集污物后的中间箱在真空状态下被吸入污物收集容器。本发明在便器与污物收集容器之间形成两级真空控制,根据如厕状态控制中间箱吸污时在常压状态、低真空状态及高真空状态切换,有效降低便器在排污时由于破真空所产生的噪音。
