[0010] The beneficial effects of this application are as follows: This application uses an exhaust fan to draw air from the suction pipe, thereby creating negative pressure in the distributor, which ultimately allows the dust collection pipes connected to the air inlets on both sides to absorb dust from the tray. The distributor, through a switching cylinder, controls the insertion depth of the insert plate, thus connecting the air inlet and outlet on one side to facilitate dust collection operations on the dust collection pipe connected to that side, greatly improving dust collection efficiency and portability.

When the exhaust fan 5 in the above design is started, it can draw air from the air intake pipe 51 to generate negative pressure, and send it to the external dust collection bag through the air exhaust pipe 52. The connection between the air intake pipe 51 and the distributor 6 can be selected to connect to the dust collection pipe that needs to be dusted, so as to switch according to actual needs.

[0014] The splitter 6 includes a pipe box 63 and a switching cylinder 64. The pipe box 63 is fixed to the top of the inner side of the fan cabinet 1. Air inlets 61 are provided on both sides of the pipe box 63, and an air outlet 62 connected to the suction pipe 51 is provided at the bottom of the pipe box 63. A U-shaped bracket 65 is provided on the side plate of the pipe box 63. The switching cylinder 64 is connected to the middle of the outer side of the U-shaped bracket 65, and a socket plate 66 is connected to the inner side of the U-shaped bracket 65. The middle of the socket plate 66 is connected to the telescopic rod of the switching cylinder 64. The pipe box 63 designed above has pipes to connect the air inlets 61 on both sides to the air outlet 62 at the bottom. Different insertion depths of the socket plate 66 allow for connection between the air outlet 62 and one of the air inlets 61.

[0015] The socket bracket 66 includes a horizontal plate 661 vertically connected to the switching cylinder 64 and insert plates 662 vertically fixed to both sides of the horizontal plate 661; the side end of the pipe box 63 is provided with a slot 631 corresponding to the insert plate 662; wherein, the two insert plates 662 are provided with through holes 663 of different depths and which do not overlap in the side direction. In the above design, the two insert plates 662 are provided with through holes 663 of different depths. When the switching cylinder 64 extends, one through hole 663 can be connected to the air inlet 61 on the same side, while the insert plate 662 on the other side seals the air inlet 61 on the same side; when the switching cylinder 64 retracts, the other socket can be connected to the air inlet 61 on the same side, while the insert plate 662 on that side seals the air inlet 61 on the same side.

[0016] Both the intake duct 51 and the exhaust duct 52 are equipped with side pipes 53; the side pipe 53 of the intake duct 51 is connected to a ball valve 54; the side pipe 53 of the exhaust duct 52 is equipped with a plug 55.

[0017] A control box 7 is located on the side wall of the fan cabinet 1. Multiple button panels 8 are located above the control box 7, each containing multiple buttons 81. The control box 7 houses a main control PLC, which is connected to the exhaust fan 5 and the button panels 8. A pipeline solenoid valve 71 is located at the rear of the control box 7, and this valve is also connected to the main control PLC. The multiple buttons 81 on the button panels 8 control the start and stop of the exhaust fan 5 and the extension and retraction of the switching cylinder 64.

[0018] The fan cabinet 1 has a first opening 11 at its lower end, and the shelf 4 has a second opening 41 corresponding to the first opening 11. The second opening 41 corresponds to the air outlet of the exhaust fan 5. The top of the fan cabinet 1 has multiple pipe grooves 12. In the above design, both the first opening 11 and the second opening 41 correspond to the air outlet of the exhaust fan 5, which facilitates the exhaust of the exhaust fan 5.

[0019] Specific operating procedure: Different tray dust collection pipes are passed through the pipe groove 12 and connected to the air inlets 61 on both sides of the distributor 6. The suction pipe 51 of the exhaust fan 5 is connected to the air outlet 62 of the distributor 6, and the exhaust pipe 52 is connected to an external dust collection bag to collect dust. Then, the exhaust fan 5 and the pipeline solenoid valve 71 are started via the button panel 8, thereby controlling the extension and retraction of the switching cylinder 64 to select the corresponding dust collection pipe connected to the air inlet 61. The exhaust fan 5 keeps the dust collection pipe in a negative pressure state to facilitate the suction of dust from the tray.
