The air jet chamber 110 and the collecting chamber 120 are connected by filtering, and a magnetic suction mechanism is arranged in the magnetic suction chamber 130 for applying magnetic force to the air jet chamber 110 and the collecting chamber 120.

[0025] In this embodiment, Figure 1 and Figure 2 As shown, the magnetic attraction mechanism includes a rotating roller 200 and a magnetic attraction component. The rotating roller 200 is rotatably connected to the inner wall of the magnetic attraction cavity 130.

The magnetic attraction roller surface 210 and the non-magnetic attraction roller surface 220 are mirror-imaged along the longitudinal section of the rotating roller 200, and the magnetic attraction component is laid on the magnetic attraction roller surface 210.

[0026] During implementation, when the rotating roller 200 is rotatably connected to the magnetic suction chamber 130 , the roller axis of the rotating roller 200 is arranged parallel to the ground.

[0027] In this way, the magnetic roller surface 210 or the non-magnetic roller surface 220 can be turned upward by rotating the rotating roller 200 to open or close the magnetic force applied to the jet chamber 110 and the collection chamber 120, which is more controllable.

[0028] In this embodiment, the magnetic attraction component is a permanent magnet 300 , and the permanent magnet 300 is laid on the magnetic attraction roller surface 210 .

[0029] In this way, the permanent magnet 300 can make the magnetism last longer, the magnetism more stable, and the chip removal effect more sustainable.

[0030] In this embodiment, Figure 1 and Figure 2 As shown, a ratchet 410 is provided on the outer wall of the rotating roller 200 along the circumferential direction, a pawl 420 matching with the ratchet 410 is provided at the bottom of the magnetic suction cavity 130, and a spring is provided on the ratchet 410, and the rebound direction of the spring is opposite to the supporting direction of the pawl 420.

[0031] In this way, the magnetic roller surface 210 and the non-magnetic roller surface 220 of the rotating roller 200 can be positioned through the cooperation of the ratchet wheel 410 and the clockwork spring, without the need for manual positioning.

[0032] In this embodiment, Figure 1 and Figure 2 As shown, one end of the bearing of the rotating roller 200 extends out of the housing 100 and is connected to a rotating handle 500 .

[0033] In this way, the magnetic roller surface 210 and the non-magnetic roller surface 220 on the rotating roller 200 can be adjusted by rotating the handle 500 to select whether to apply magnetic attraction force to the jet chamber 110 and the collection chamber 120 .

[0036] In this way, the air nozzle 600 can rotate to make the chip removal gas ejected from the air nozzle rotate in a circle in the air injection chamber 110, with more injection angles and higher chip removal efficiency.

[0037] In this embodiment, Figure 1 and Figure 2 As shown, the jet mechanism also includes a motor 710, a first gear 720 and a second gear 730. The motor 710 is mounted on the inner top wall of the jet chamber 110. The first gear 720 is mounted on the outer top of the jet chamber 110 and is transmission-connected to the motor 710. The jet nozzle 600 has a transmission part, which protrudes upward from the top wall of the jet chamber 110. The second gear 730 is mounted on the transmission part and meshes with the first gear 720.

[0038] During implementation, there are two air nozzles 600 , each of which is equipped with a second gear 730 , and the second gears 730 on the two air nozzles 600 are meshed with the first gear 720 .

[0039] In this way, the motor 710 drives the two air nozzles 600 to rotate and spray gas, so that the chip removal effect is further improved, and the transmission structure is simple and the manufacturing cost is low.

[0040] In this embodiment, Figure 1 and Figure 2 As shown, a filter screen 800 is provided between the jet chamber 110 and the collection chamber 120 .

[0041] In this way, the filter 800 can provide space for chips to pass through. When the chips need to be cleaned, the processed metal mold is placed in the jet chamber 110 for jet chip removal. The chips removed by the jet are metallic in nature and will be sucked from the filter 800 into the collection chamber 120 by the magnetic suction mechanism in the magnetic suction chamber 130.
