the side wall of the negative pressure generating pipe 33, which is close to one end of the sealing plate 34, is provided with a negative pressure suction port 35, and the negative pressure suction port 35 is connected with a return air pipe 32 at one end of the return air port 31.
Because the object to be adsorbed by the utility model is finer metal dust particles, when the metal dust particles are adsorbed, if the dust particles are further sucked by adopting a fan suction mode, the finer dust particles easily pass through the filter device and enter the fan, and the inside of the fan is conductive, so that the fan is failed.
In this embodiment, the negative pressure generating tube 33 and the fan are connected to generate negative pressure, and the negative pressure fan 37 generates negative pressure at the negative pressure generating tube 33 far away from the negative pressure fan 37 after blowing, so that the metal dust particles are prevented from being sucked into the negative pressure fan 37, and the negative pressure fan 37 can stably operate.
Specifically, the diameter of the negative pressure generating tube 33 gradually increases from the middle to the two ends, and when the air flowing at a high speed is ejected from the jet nozzle 332, the air flowing at the smaller diameter section of the negative pressure generating tube 33 flows at a higher speed, and negative pressure is generated. The negative pressure suction port 35 formed on the side wall of the negative pressure generating tube 33 is connected with one end of the air return port 31, and the air around the air return port 31 and the metal dust particles are sucked into the negative pressure generating tube 33 by sucking air at the air return port 31 through the negative pressure generated on the negative pressure generating tube 33.

The filter cover 43 is used for isolating the air at the air outlet 42 from further separation of metal dust particles, and the hemispherical filter cover 43 can increase the filtering surface area of the filter cover 43, so that the air to be filtered can pass through quickly.
The diameter of the air outlet 42 is larger than that of the air inlet 41, and the flow speed of the air can be slowed down when the air flows through the air outlet 42, so that the influence of the air flowing annularly at the edge of the disc-shaped dust particle recovery bin 4 is reduced, the metal dust particles are kept at the disc-shaped edge, and the metal dust particles are thrown into the dust storage chamber 45 through the dust outlet 44 in the continuous flowing process.
