DETAILED DESCRIPTION

The nitrogen generator body 5 is provided on the top surface of the maintenance unit 4. The noise reduction unit 2 includes a soundproof box 21, which is fixedly connected to the top surface of the support frame 1. A silencing pipe 22 is sleeved inside one side of the soundproof box 21. A limit groove 23 is slidably connected inside the soundproof box 21. A door 24 is provided on one side of the soundproof box 21. A sound insulation strip 25 is provided on one side of the door 24. A heat dissipation component 26 is provided on the top surface of the soundproof box 21. The heat dissipation component 26 includes ventilation holes 261, which are formed on the support frame 1. On the top surface of the frame 1, a fixed frame 262 is fixedly connected inside the ventilation hole 261. A silent motor 263 is fixedly connected to one side of the fixed frame 262. A fan blade 264 is fixedly sleeved at the output end of the silent motor 263. The noise generated by the nitrogen generator body 5 during its operation inside the support frame 1 is isolated by the function of the soundproof box 21 itself. At the same time, the noise is further isolated by the cooperation between the soundproof strip 25 and the box door 24. Meanwhile, the silent motor 263 drives the fan blade 264 to rotate, which exhausts the heat inside the soundproof box 21. At the same time, the outside air enters the soundproof box 21 after being silenced by the silencer pipe 22, forming air circulation and preventing individual electronic components from being damaged by temperature. Example

[0032] like Figures 1-5 As shown, based on Embodiment 1, this utility model provides a technical solution: Preferably, the buffer unit 3 includes a limiting frame 31, which is slidably connected to the inner side of the limiting groove 23. A fixing hole 32 is provided inside the limiting frame 31. A hydraulic buffer rod 33 is fixedly connected to the bottom surface of the limiting frame 31. A spring 34 is sleeved on the outer side of the hydraulic buffer rod 33. One end of the spring 34 is fixedly connected to the inner bottom surface of the soundproof box 21, and the other end of the spring 34 is fixedly connected to the bottom surface of the limiting frame 31. A shock-absorbing ball 35 is fixedly connected to the bottom surface of the limiting frame 31. At the same time, during the operation of the nitrogen generator body 5, the vibration generated is buffered by the hydraulic buffer rod 33 and the spring 34, further reducing the vibration of the nitrogen generator body 5 itself and reducing the vibration noise. Example

[0033] like Figures 1-5As shown, based on Embodiment 1, this utility model provides a technical solution: Preferably, the maintenance unit 4 includes a mounting plate 41, which is slidably connected to the inside of the limiting frame 31. A support leg 42 is rotatably connected inside the mounting plate 41. One end of the support leg 42 is fixedly connected to a caster wheel 43.

Subsequently, the mounting plate 41 will be pulled and moved under the limitation of the limiting frame 31. Then, the nitrogen generator body 5 can be slid out from the inside of the soundproof box 21 for maintenance, which further facilitates the operation of workers. After the maintenance is completed, it can be pushed back and fixed.

[0035] like Figures 1-5 As shown, the noise generated by the nitrogen generator body 5 during its operation inside the support frame 1 is isolated by the soundproof box 21 itself. Furthermore, the noise is further isolated through the cooperation of the soundproof strip 25 and the box door 24. Simultaneously, the silent motor 263 drives the fan blade 264 to rotate, expelling heat from inside the soundproof box 21. Meanwhile, external air enters the soundproof box 21 after being silenced by the silencer pipe 22, creating air circulation and preventing damage to individual electronic components due to temperature fluctuations. During the operation of the nitrogen generator body 5... The vibration generated is buffered by the hydraulic buffer rod 33 and the spring 34, further reducing the vibration of the nitrogen generator body 5 itself and reducing vibration noise. During long-term use, pulling the T-shaped rod 44 will extend the spring 45 and remove the support leg 42. The support leg 42 will then contact the ground via the caster wheel 43. The mounting plate 41 will then be pulled and moved under the limit of the limit frame 31. The nitrogen generator body 5 can then be slid out of the soundproof box 21 for maintenance, making it easier for workers to operate. After maintenance, it can be pushed back in for fixation.
