DETAILED DESCRIPTION

[0021] In order to make the technical means, creative features, objectives and effects achieved by the present invention easy to understand, the present invention is further described below in conjunction with specific implementation methods.

[0022] like Figure 1-4 As shown, a segmented detachable air collecting hood includes a hood body 1 and a tube body 2, a disassembly assembly 3 is installed between the top of the hood body 1 and the bottom end of the tube body 2, a dust collecting assembly 4 is installed inside the hood body 1, and the disassembly assembly 3 includes a top plate 5 and a bottom plate 6, the top plate 5 is fixedly installed on the top of the hood body 1, and the bottom plate 6 is fixedly installed on the bottom end of the tube body 2, rails 7 are installed on both sides of the top of the top plate 5 and through the inside of the bottom plate 6, positioning holes 8 are opened on the outer sides of the two rails 7 near the front ends, guide rods 9 are movably installed through the inside of the top plate 5 near the front ends on both sides, springs 10 are installed on the periphery of the guide rods 9, and pull blocks 11 are fixedly installed on the outer ends of the guide rods 9.

[0023] In this embodiment, the cross-section of the rail 7 is umbrella-shaped, and the rail 7 runs through the interior of the bottom plate 6 and slides back and forth. The top plate 5 slides on the top of the bottom plate 6 through the rail 7, which facilitates the disassembly and assembly between the cover body 1 and the tube body 2.

[0024] In this embodiment, the positions of the positioning hole 8 and the guide rod 9 correspond to each other. The guide rod 9 is located inside the top plate 5 and is slidably arranged. The guide rod 9 slides inwardly through the spring 10, so that the rail 7 is automatically fixed when it is fully inserted into the bottom plate 6.

[0025] In this embodiment, the inner end of the guide rod 9 is located in the positioning hole 8 and is clamped, passing through the interior of the bottom plate 6 and the top plate 5 and communicating with the tube body 2. The guide rod 9 is clamped into the positioning hole 8 to fix the top plate 5 and the bottom plate 6.

[0026] In this embodiment, the dust collecting assembly 4 includes four support rods 12, and the four support rods 12 are fixedly installed inside the cover body 1 at a position close to the top. The bottom ends of the four support rods 12 are fixedly installed with the same bottom ring 13, and a plurality of filter holes 14 are opened through the top of the bottom ring 13. The inner ring of the bottom ring 13 is fixedly installed with a support frame 15, and the top of the support frame 15 is fixedly installed with a collecting cover 16. The fallen dust is collected through the bottom ring 13 and the collecting cover 16, and is re-sucked into the tube body 2 through the filter holes 14 during the air collection process.

[0027] In this embodiment, the collecting hood 16 is arranged in a cone shape, and a plurality of identical filter holes 14 are opened through the top of the collecting hood 16 , so that dust is collected through the collecting hood 16 , and the air flow on both sides of the hood body 1 is enhanced at the same time.

[0028] In this embodiment, the top view of the bottom ring 13 is annular, and the collecting cover 16 is fixedly installed between the support frame 15 and the bottom ring 13. The bottom ring 13 is used to collect dust falling from the inner wall of the tube body 2 to reduce the falling of dust.

[0029] It should be noted that the utility model is a segmented detachable air collecting hood. When in use, the hood body 1 is first connected to the tube body 2, and the rail 7 on the top of the top plate 5 is inserted into the bottom plate 6, and the two pull blocks 11 are pulled to slide the guide rod 9 outward. When the rail 7 is fully inserted, the guide rod 9 is automatically inserted into the positioning hole 8 by the action of the spring 10 for fixation, and then the segmented disassembly is performed. During the air collection process, the smoke is sucked in through the hood body 1, and the dust in the bottom ring 13 and the collection hood 16 is sucked into the tube body 2 through the filter hole 14 and transported to the purification equipment. When it is not in use, the shaking of the tube body 2 can easily cause the dust on the inner wall to fall off. Since the fallen dust adheres to each other, it is collected through the bottom ring 13 and the collection hood 16 to reduce the dust falling on the equipment.

[0030] The above shows and describes the basic principle and main features of the utility model and the advantages of the utility model. Those skilled in the art should understand that the utility model is not limited by the above embodiments.
