Abstract
Description
Technical Field
[0001] This application relates to the field of nitrogen generator technology, and in particular to a nitrogen generator with noise reduction function. Background Technology
[0002] The field of nitrogen generator technology refers to the research and application of technologies related to nitrogen production, separation, and purification, involving technologies such as air separation, gas compression, cryogenic cooling, and molecular sieve adsorption. A nitrogen generator is a device within this technical field specifically designed to separate nitrogen from the air. The working principle of nitrogen generators is typically based on physical separation methods, such as pressure swing adsorption technology or cryogenic condensation technology, which efficiently and economically obtain nitrogen with high purity. A search revealed Chinese Patent Publication No. CN219279496U, which discloses a nitrogen generator with noise reduction function. The generator includes a main body, a moving mechanism, a buffer mechanism, and a sound insulation mechanism. The top end of the moving mechanism is fixedly connected to the bottom end of the buffer mechanism, the top end of the buffer mechanism is fixedly connected to the bottom end of the nitrogen generator main body, and the bottom end of the sound insulation mechanism is fixedly connected to the top end of the buffer mechanism. This invention uses first buffer springs at both ends of the movable plate connected to the inner wall of the movable shell to buffer the movement of the movable plate and absorb the impact force. Two mounting rods are connected by second buffer springs, ensuring that the rollers at the ends of the mounting rods always remain in close contact with the inner wall of the side of the shell. When the movable shell moves, the mounting rods move along the pins on the side of the connecting block and are buffered by the second buffer springs, thereby reducing the impact force on the movable plate, reducing vibration, which helps to reduce noise generation and minimize environmental impact. In existing technologies, some nitrogen generators rely solely on heat exchange plates for heat dissipation. This design leads to uneven heat dissipation, particularly creating dead zones in certain areas of the heat exchange plates, hindering effective heat dissipation. This results in excessively high temperatures during operation, impacting equipment efficiency and lifespan. Furthermore, the existence of these dead zones limits the heat dissipation effect of the nitrogen generator and may even trigger overheat protection mechanisms. Utility Model Content
[0003] The purpose of this application is to provide a nitrogen generator with noise reduction function, which aims to improve the problem that some nitrogen generators in the prior art only use heat exchange plates for heat dissipation during use, resulting in heat dissipation dead zones.
[0004] The nitrogen generator with noise reduction function provided in this application adopts the following technical solution: a nitrogen generator with noise reduction function includes a nitrogen generator mounting block, a nitrogen generator body is fixedly connected to the top of the nitrogen generator mounting block, a portable moving mechanism is fixedly connected to the bottom of the nitrogen generator body, a sound insulation cover is fixedly connected to the top of the nitrogen generator mounting block, and an adjustment mechanism is fixedly connected to the top of the nitrogen generator mounting block.

[0005] The above solution allows the portable mobile mechanism to drive the mobile base via a sliding push rod inside the mobile housing, which in turn drives the roller mounting block and rolling wheels to move the nitrogen generator. The support legs provide stable support, and the guide and protective blocks ensure smooth sliding of the mobile base, balancing mobility and stability, making it convenient for the nitrogen generator to be moved and fixed in different scenarios.

The transmission shaft and linkage shaft are coupled by a belt to achieve linkage between the heat dissipation and adjustment mechanisms. The partition block supports the stable rotation of the fan and can dissipate heat simultaneously when adjusting the soundproof cover, ensuring that the nitrogen generator reduces noise while dissipating heat efficiently, and avoiding internal overheating that could affect operation.
[0008] As a further description of the above technical solution: the adjustable sealing assembly includes two push rod mounting blocks, which are respectively fixedly connected to the front and rear sides of the soundproof cover. An adjusting push rod is fixedly connected to the bottom of the push rod mounting block, and a sealing block is fixedly connected to the driving end of the adjusting push rod. Two guide rails are fixedly connected to the front and rear sides of the soundproof cover, and the outer side of the sealing block is slidably connected to the inside of the guide rails.
[0009] The above solution allows for flexible adjustment of the sealing state of the soundproof cover by using adjustable push rods at the front and rear of the cover to drive the sealing block and slide it along the guide rail. This enhances the sound insulation effect and allows for adjustment of the opening size as needed, balancing noise reduction and sealing with ease of operation, thus adapting to different usage scenarios.
[0010] As a further description of the above technical solution: the soundproof cover includes a soundproof outer shell, the bottom of which contacts the top of the nitrogen generator mounting block, a soundproof layer is fixedly connected inside the soundproof outer shell, a soundproof inner shell is fixedly connected inside the soundproof layer, the top of the partition block is fixedly connected to the bottom of the soundproof outer shell, through holes are opened inside the soundproof layer and the soundproof inner shell, the outside of the partition block contacts the inner wall of the through holes, and the bottom of the motor protection block is fixedly connected to the top of the soundproof outer shell.
[0011] The above solution employs a multi-layered structure consisting of a soundproof outer shell, a soundproof layer, and a soundproof inner shell to enhance noise reduction. The partition blocks are connected to each layer through through holes and support the fan. The motor protection block is fixed to the top. The overall structure is compact and can effectively block the operating noise of the nitrogen generator while ensuring the heat dissipation components are installed securely, thus achieving efficient noise reduction and stable equipment operation.
[0012] As a further description of the above technical solution: the motor protection block has an internal mounting groove, the drive motor and the motor mounting block are both fixedly connected to the inside of the mounting groove, the motor protection block has ventilation holes on the left and right sides, and the belt is slidably connected to the outside of the ventilation holes and slidably connected to the inside of the ventilation holes.
[0013] The above solution involves fixing the drive motor to the motor mounting block via the mounting slot, and ensuring smooth belt drive through the ventilation holes on both sides. This also helps to dissipate heat from the motor, preventing performance issues caused by overheating, ensuring the stability of the linkage between the drive cooling components and the adjustment mechanism, and improving the overall reliability of the nitrogen generator.

[0015] The above solution involves adjusting the guide block by cooperating with the sliding adjustment block through a sliding groove. The front and rear guide grooves guide the guide block, ensuring that the sliding adjustment block slides smoothly when rotating along the screw, avoiding deviation, improving the accuracy and stability of the adjustment mechanism, making the soundproof cover adjustment process smooth, and ensuring the reliability of the nitrogen generator adjustment operation.
[0016] As a further description of the above technical solution: the soundproof cover has heat dissipation vents on both the front and rear sides, and the outside of the heat dissipation vents is in contact with the adjacent side of the two sealing blocks.
[0017] The above solution involves opening heat dissipation vents at the front and back of the soundproof cover, which contact and cooperate with the sealing block. When the sealing block slides along the guide rail, the opening and closing degree of the heat dissipation vents can be adjusted. This can both enhance the sound insulation effect by sealing the heat dissipation vents and open the heat dissipation vents as needed, achieving efficient heat dissipation with the help of the driving heat dissipation component, thus taking into account both noise reduction and heat dissipation requirements.
[0018] In summary, this application includes at least one of the following beneficial technical effects: 1. In this utility model, the soundproof outer shell slidably connected to the top of the nitrogen generator mounting block absorbs the noise generated by the nitrogen generator body during operation through the cooperation of the soundproof layer and the soundproof inner shell fixed inside the soundproof outer shell, thereby improving the practicality of the device. The motor protection block fixed to the top of the soundproof outer shell provides necessary protection for the drive motor. When the drive motor fixed inside the motor protection block is started by the motor mounting block, it drives the transmission shaft fixed outside the drive end of the drive motor to rotate. The belt outside the transmission shaft drives the linkage shaft to rotate, which in turn drives the screw fixed to rotate. Finally, the sliding adjustment block slides up and down, and the soundproof outer shell slides up and down through the sliding adjustment block, thereby achieving the sealing and noise reduction effect of the nitrogen generator body, and thus improving the practicality of the device. 2. In this utility model, the sliding push rod, which is fixed inside the movable housing by the push rod support block, is activated, which drives the movable base fixed to the drive end of the sliding push rod to slide up and down. This pushes the roller mounting block fixed to the bottom of the sliding push rod to slide, so that the rolling wheel rotatably connected inside the roller mounting block comes into contact with the ground, thereby improving the portability of the device. During the sliding of the movable base, multiple guide and protective blocks fixed inside the movable housing provide necessary guidance for the movable base, thereby ensuring the stability of the movable base during the sliding process.

The nitrogen generator body 2 is fixedly connected to the top of the nitrogen generator mounting block 1. The nitrogen generator body 2 includes key components such as a compressor and a filter, and nitrogen generation is achieved through internal and external control devices. A portable moving mechanism 7 is fixedly connected to the bottom of the nitrogen generator body 2, allowing the nitrogen generator to be moved or its position adjusted during operation, which is especially suitable for use in different locations. A soundproof cover 5 is fixedly connected to the top of the nitrogen generator mounting block 1. The main function of the soundproof cover 5 is to reduce the noise of the nitrogen generator during operation, making the device more suitable for places where a quiet environment is required. An adjustment mechanism 3 is fixedly connected to the top of the nitrogen generator mounting block 1, which is used to adjust the position of the soundproof cover 5 to adapt to different operating requirements of the nitrogen generator. Specifically, when the nitrogen generator is working, the sliding push rod 72 of the portable moving mechanism 7 drives the moving base 75 to descend, causing the rolling wheels 77 to contact the ground and move the nitrogen generator to the working position. After that, the sliding push rod 72 retracts, and the support legs 78 provide stable support. The nitrogen generator body 2 is started, simultaneously driving the drive motor 42 of the heat dissipation assembly 4 to rotate the fan 44. This, via the belt 35, links the lead screw 32 of the adjusting mechanism 3, causing the sliding adjusting block 34 to slide, thus adjusting the position of the soundproof cover 5.

Specifically, when the heat dissipation component 4 is running, the drive motor 42 drives the belt 35 to rotate through the transmission shaft 36. The belt 35 drives the linkage shaft 33 to rotate. The linkage shaft 33 drives the lead screw 32 to rotate within the adjusting guide block 31. When the lead screw 32 rotates, it drives the sliding adjusting block 34 to slide up and down within the sliding groove. The guide block outside the sliding adjusting block 34 moves synchronously along the guide groove, thereby adjusting the position of the soundproof cover 5. At the same time, the adjustable sealing component 6 cooperates with the adjustment action of the soundproof cover 5.

The drive motor 42 is fixedly connected inside the top of the motor mounting block 43. The fan 44 is fixedly connected to the bottom of the drive end of the drive motor 42. A drive shaft 36 is fixedly connected to the outside of the drive end of the drive motor 42. A belt 35 is internally coupled between the linkage shaft 33 and the drive shaft 36. The linkage shaft 33 transmits the power of the drive motor 42 to the adjustment mechanism 3 to adjust the position of the soundproof cover 5. The soundproof cover 5 is fixedly connected to the partition block 45. The fan 44 is responsible for air circulation. The partition block 45 enables the cooling mechanism to operate efficiently through physical isolation. The fan 44 is externally rotatably connected to the inside of the partition block 45. The motor protection block 41 has a mounting groove inside. The drive motor 42 and the motor mounting block 43 are both externally fixedly connected to the inside of the mounting groove. Ventilation holes are opened on the left and right sides of the motor protection block 41. The belt 35 is slidably connected to the outside of the ventilation hole and slidably connected to the inside of the ventilation hole. Specifically, when the heat dissipation component 4 is working, the drive motor 42 starts in the mounting slot of the motor protection block 41. Its drive end drives the fan 44 to rotate in the partition block 45. At the same time, the transmission shaft 36 outside the drive end rotates and passes through the ventilation holes on the left and right sides of the motor protection block 41 via the belt 35. It is coupled with the linkage shaft 33 to drive the linkage shaft 33 to rotate, thereby causing the lead screw 32 to rotate in the adjustment guide block 31, driving the sliding adjustment block 34 to move along the sliding groove.
[0024] The adjustable sealing assembly 6 includes two push rod mounting blocks 61, which are fixedly connected to the front and rear sides of the soundproof cover 5 respectively. An adjusting push rod 62 is fixedly connected to the bottom of the push rod mounting block 61.

The outside of the heat dissipation vents is in contact with the adjacent side of the two sealing blocks 63. Specifically, when the adjustable sealing assembly 6 is working, after the adjusting push rod 62 is started, it drives the sealing block 63 to slide in the guide rail 64. When the sealing block 63 moves along the guide rail 64, its adjacent side contacts the heat dissipation vents on the front and rear sides of the soundproof cover 5. The sliding distance of the sealing block 63 is controlled by adjusting the extension and retraction of the push rod 62, thereby adjusting the opening and closing state of the heat dissipation vents.

A push rod support block 73 is fixedly connected inside the mobile housing 71. A sliding push rod 72 is fixedly connected inside the push rod support block 73. By extending and retracting the sliding push rod 72, the mobile base 75 is driven to slide up and down, making it easy to adjust the height as needed. The driving end of the sliding push rod 72 is fixedly connected to the mobile base 75. The movable base 75 is externally slidably connected to the inside of the movable housing 71. Multiple roller mounting blocks 76 are fixedly connected to the bottom of the movable base 75. The roller mounting blocks 76 provide the part that contacts the ground during movement.

Multiple guide protection blocks 74 are fixedly connected inside the movable housing 71. The guide protection blocks 74 provide additional stability and protection for the sliding push rod 72 through cooperation with the movable base 75. The guide protection blocks 74 are externally slidably connected to the inside of the movable base 75. Specifically, when the portable mobile mechanism 7 is working, the sliding push rod 72 extends and retracts within the push rod support block 73, driving the mobile base 75 to slide up and down within the mobile housing 71. The mobile base 75 drives the roller mounting block 76 and the rolling wheel 77 to rise and fall, and guides the protective block 74 to be embedded inside the mobile base 75 to guide its sliding. When the rolling wheel 77 contacts the ground, it can push the nitrogen generator to move. After moving to the designated position, the sliding push rod 72 retracts, and the support leg 78 lands on the ground for support.

A soundproof layer 52 is fixedly connected inside the soundproof outer shell 51, and a soundproof inner shell 53 is fixedly connected inside the soundproof layer 52. Through the design of the soundproof layer 52 and the soundproof inner shell 53, the noise generated during machine operation is effectively reduced, ensuring a quiet working environment. The top of the partition block 45 is fixedly connected to the bottom of the soundproof outer shell 51. Through holes are opened inside the soundproof layer 52 and the soundproof inner shell 53. The outside of the partition block 45 contacts the inner wall of the through holes. The bottom of the motor protection block 41 is fixedly connected to the top of the soundproof outer shell 51. Specifically, when the soundproof cover 5 is working, the bottom of the soundproof outer shell 51 contacts the top of the nitrogen generator mounting block 1, and the internal soundproof layer 52 and the soundproof inner shell 53 form a multi-layer soundproof structure. The partition block 45 passes through the through hole of the soundproof layer 52 and the soundproof inner shell 53, and is fixed to the bottom of the soundproof outer shell 51 at the top, supporting the rotation of the fan 44 of the drive heat dissipation component 4. The motor protection block 41 is fixed to the top of the soundproof outer shell 51 to ensure the installation and operation of the drive motor 42.
[0027] The implementation principle of this application embodiment is as follows: The soundproof shell 51, which is slidably connected to the top of the nitrogen generator mounting block 1, absorbs the noise generated by the nitrogen generator body 2 during operation through the cooperation of the soundproof layer 52 and the soundproof inner shell 53 fixed inside the soundproof shell 51, thereby improving the practicality of the device. The motor protection block 41, which is fixed to the top of the soundproof shell 51, provides necessary protection for the drive motor 42. The drive motor 42, which is fixed inside the motor protection block 41 by the motor mounting block 43, is started, which drives the transmission shaft 36 fixed outside the drive end of the drive motor 42 to rotate. The belt 35 outside the transmission shaft 36 drives the linkage shaft 33 to rotate. The linkage shaft 33 drives the screw 32 fixed to rotate, which finally drives the sliding adjustment block 34 to slide up and down. Finally, the sliding adjustment block 34 drives the soundproof shell 51 to slide up and down, thereby achieving the sealing and noise reduction effect of the nitrogen generator body 2, thereby improving the practicality of the device. Meanwhile, as the drive motor 42 drives the transmission shaft 36 to rotate, the drive motor 42 drives the fan 44 fixed at the drive end of the transmission shaft 36 to rotate, thereby quickly sending external air into the interior of the soundproof inner shell 53, thereby quickly cooling the nitrogen generator body 2, thus preparing it for the next use and improving the practicality of the device. During the operation of the device, when the nitrogen generator body 2 becomes too hot, the adjusting push rod 62, which is fixed to the front and rear sides of the soundproof shell 51 by the push rod mounting block 61, can be activated. The adjusting push rod 62 drives the sealing block 63, which is fixed to the driving end of the adjusting push rod 62, to slide, thereby opening the air inlets inside the soundproof shell 51, the soundproof layer 52, and the soundproof inner shell 53. This allows the air inside the soundproof shell 51 to exchange heat with the outside, thereby reducing the temperature of the nitrogen generator body 2. During the sliding of the sealing block 63, the two guide rails 64 fixed to the front and rear sides of the soundproof shell 51 provide necessary guidance for the soundproof inner shell 53. The sliding push rod 72, which is fixed inside the movable housing 71 by the push rod support block 73, is activated, which drives the movable base 75, which is fixed at the drive end of the sliding push rod 72, to slide up and down. This pushes the roller mounting block 76, which is fixed at the bottom of the sliding push rod 72, to slide, so that the rolling wheel 77, which is rotatably connected inside the roller mounting block 76, comes into contact with the ground, thereby improving the portability of the device. During the sliding process of the movable base 75, multiple guide and protective blocks 74, which are fixed inside the movable housing 71, provide necessary guidance for the movable base 75, thereby ensuring the stability of the movable base 75 during the sliding process.
