[0013] (3) Beneficial effects

[0014] The utility model provides a silent cabin with a ventilation structure, which has the following beneficial effects:

[0015] 1. In the present invention, the air intake fan draws fresh air from the outside into the air intake pipe, and finally discharges it into the interior of the cabin through multiple air intake nozzles provided on the guide pipe. During this air intake process, the noise of the air intake fan and the airflow itself can be reduced by the first muffler. The internal sound-absorbing material, such as glass fiber or polyurethane foam, can absorb the sound waves generated by the air flow and reduce the noise level; thereby ultimately ensuring that the cabin is in a quiet state, and the personnel in the cabin are not affected by the ventilation system and can work normally.

[0016] 2. In the present invention, the exhaust fan discharges the turbid air inside the cabin. The second silencer can absorb the noise of the exhaust fan, thereby reducing the impact on the interior of the cabin. BRIEF DESCRIPTION OF THE DRAWINGS

[0023] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments.

[0024] See also Figures 1 to 5 The utility model provides a technical solution: a silent cabin with a ventilation structure, comprising a cabin body 1, an air intake fan 2 fixedly mounted on the top of the cabin body 1, and a first muffler 3 fixedly mounted on the air outlet end of the air intake fan 2. The end of the first muffler 3 is fixedly connected to an air intake pipe 4, and the other end of the air intake pipe 4 passes through the interior of the cabin body 1 and is fixedly connected to a horizontal conducting pipe 13. A plurality of air intake nozzles 9 distributed at equal distances are connected to the conducting pipe 13, and a sound insulation component is provided on the air intake pipe 4.

[0025] The air intake fan 2 draws fresh air from the outside into the air intake pipe 4, and finally discharges it into the interior of the cabin 1 through multiple air intake nozzles 9 arranged on the conducting pipe 13. During this air intake process, the noise of the air intake fan 2 and the airflow itself can be reduced by the first silencer 3. The sound-absorbing material inside the first silencer 3, such as glass fiber or polyurethane foam, can absorb the sound waves generated by the air flow and the sound waves generated by the operation of the air intake fan 2, thereby reducing the noise level; thereby ultimately ensuring that the cabin 1 is in a quiet state, and the people in the cabin are not affected by the ventilation system and can work normally; and the provision of a sound insulation component can reduce the noise of the air intake pipe 4, thereby preventing external noise from being transmitted to the cabin 1 through the air intake pipe 4.

[0026] The sound insulation assembly includes two half sound insulation covers 5, both of which are arranged on the air intake pipe 4, and the two half sound insulation covers 5 are sealed and connected to each other. Positioning blocks 6 are fixedly connected to the half sound insulation covers 5, and the positioning blocks 6 are connected by fasteners.

[0027] The two half soundproof covers 5 achieve the purpose of reducing the noise of the air intake pipe 4, preventing external noise from entering the cabin 1 through the air intake pipe 4, and the two half soundproof covers 5 are in close contact through fasteners to improve the sound insulation effect.

[0028] The semi-soundproof cover 5 is made of a polyester fiber board or a rock wool board, which is lightweight, effectively absorbs sound, is resistant to high temperatures, and has a good sound insulation effect.

[0029] The fastener includes a bolt 7 and a nut 8 threadedly sleeved on the end of the bolt 7 . A positioning hole 601 is opened on the positioning block 6 , and the bolt 7 is installed through the positioning hole 601 of the positioning block 6 .

[0030] When connecting the two half soundproof covers 5, the threaded end of the bolt 7 is passed through the positioning hole 601 on the positioning block 6, and then the nut 8 is screwed onto the threaded end of the bolt 7. The nut 8 contacts the positioning block 6 to achieve locking.

[0031] A second muffler 10 is fixedly mounted on the side wall of the cabin body 1 , an exhaust fan 11 is fixedly mounted on the end of the second muffler 10 , and a dustproof net 12 is fixedly mounted on the end of the exhaust fan 11 .

[0032] The exhaust fan 11 discharges the turbid air inside the cabin 1 . The second muffler 10 can absorb the noise of the exhaust fan 11 , thereby reducing the impact on the interior of the cabin 1 .

[0033] The dustproof net 12 is disc-shaped and is threadedly connected to the end of the exhaust fan 11, which makes it easy to disassemble the dustproof net 12 for cleaning. A similar dustproof structure can also be installed on the intake fan 2 to prevent dust from entering the interior of the cabin 1; both the exhaust fan 11 and the intake fan 2 use low-noise fans to reduce the noise generated during the ventilation process.
