The present invention relates to a rapid suction-based filtering device, comprising a filter and a vacuum pump. A suction-based filtering end of the filter is gas-connected to a suction end of the vacuum pump, and the suction-based filtering end is further gas-connected to an exhaust end of the vacuum pump. Preferably, the suction-based filtering end is gas-connected to the suction end and the exhaust end through a directional valve. Alternatively, the function of the directional valve is implemented through a first control valve and a second control valve, or the function of the directional valve is implemented through a third control valve, a fourth control valve, a fifth control valve, and a sixth control valve. The exhaust end is gas-connected to the suction-based filtering end through an air filter. The present invention further comprises a four-way and 3 stop valves. The number of filters is 3. The suction-based filtering end is gas-connected to the four-way through the stop valve. The four-way is gas-connected to the suction end and the exhaust end. The stop valves are manual stop valves. The filter is a suction-based filtering bottle. The present invention is cleverly designed and structurally simple, and during suction-based filtering, the filter is unlikely to be blocked, so as to improve suction-based filtering efficiency and speed, thereby resulting in suitability in large-scale promotion and application. |
