Description

Technical Field

[0001] This utility model relates to the technical field of oxygen generator devices, specifically a high-efficiency noise-reducing oxygen generator. Background Technology

[0002] An oxygen concentrator is a machine that produces oxygen. Its principle is based on air separation technology. First, air is compressed at high density, and then the different condensation points of the components in the air are used to separate the gas and liquid at a certain temperature. Then, distillation is carried out to separate it into oxygen and nitrogen. In general, because it is mostly used to produce oxygen, people usually call it an oxygen concentrator. Since oxygen and nitrogen have a wide range of uses, oxygen concentrators are widely used in the national economy, especially in industries such as metallurgy, chemical industry, petroleum, and defense. The first countries in the world to produce oxygen concentrators were Germany and France. Linde Company of Germany produced an oxygen concentrator in 1903. Following Germany, Air Liquefaction Company of France also began producing oxygen concentrators in 1910. Oxygen concentrators have a history of more than 100 years since 1903.

[0003] With the advancement of technology, oxygen concentrators have become more diverse, with various effects designed to meet different needs. However, all oxygen concentrators share a common characteristic: they generate significant noise during the oxygen production process. Furthermore, because oxygen concentrators require air inlets and outlets, the sound source can escape to the outside through these openings, making it difficult to effectively control the generation and propagation of noise. The noise indicates the presence of vibrations during the internal oxygen production process, which may cause unavoidable damage to the oxygen concentrator. Utility Model Content

[0005] To achieve the above objectives, this utility model provides the following technical solution: a high-efficiency noise-reducing oxygen generator, comprising an outer shell, a flip cover mounted on the upper end of the outer shell, an air inlet on one side surface of the outer shell, a pad mounted on the bottom of the outer shell, an air filter box mounted inside the air inlet, a sound-absorbing plate mounted at the rear end of the air filter box, sound-absorbing side plates mounted at the upper and lower ends of the sound-absorbing plate, a compressor connected to the rear end of the air filter box, an input pipe mounted at the rear of the compressor, and a molecular sieve adsorption tower mounted at the rear end of the input pipe.

[0006] Preferably, a solenoid valve is installed at the upper end of the molecular sieve adsorption tower, and an attachment plate is provided on the surface of the molecular sieve adsorption tower, with a buffer spring installed at the upper end of the attachment plate.

[0007] Preferably, the other end of the buffer spring is mounted on the surface of the bonding plate, and the bonding plate is mounted on the inner surface of the outer casing.

[0008] Preferably, a sound-absorbing surface layer is installed on the inner side of the outer shell, and an output pipe is installed at the lower end of the molecular sieve adsorption tower, with a flow meter pipe installed on the outer side of the output pipe.

[0011] Compared with the prior art, the beneficial effects of this utility model are:

[0012] 1. Compared with other high-efficiency noise reduction oxygen generators, this device mainly avoids the generation of noise during oxygen production by reducing the vibration of the internal molecular sieve adsorption tower. In addition, the device is equipped with a sealed environment made of sound-absorbing materials in various internal structures, which, together with the sound-absorbing layer on the inner surface, can greatly reduce the noise generated inside and effectively prevent the generation of noise. This is more effective than general noise reduction methods and can also protect the inside of the device.

[0013] 2. In addition, the device itself avoids the installation of complicated noise reduction mechanisms in its design, and only uses the assembly of some noise reduction materials to reduce noise, making the internal structure of the device clear and making subsequent disassembly and maintenance simpler and more convenient. Furthermore, the overall operation is also simple and effective. Attached Figure Description

[0018] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0019] Please see Figures 1 to 3 This utility model provides a technical solution:

[0020] refer to Figure 1 The main body is an outer shell 2. A flip cover 1 is installed on the upper end of the outer shell 2. The flip cover 1 is installed at the top to keep the whole device sealed and prevent internal noise from spreading to the outside. An air inlet is provided on one side surface of the outer shell 2. A pad is installed at the bottom of the outer shell 2. An air filter box 9 is installed inside the air inlet. The air filter box 9 wraps the air inlet, not only filtering the incoming air, but also keeping the inside sealed. A sound-absorbing plate is installed at the rear end of the air filter box 9. Sound-absorbing side plates 3 are installed at the upper and lower ends of the sound-absorbing plate. The sound-absorbing plate and the sound-absorbing side plates 3 form a sound-absorbing box, which wraps the compressor 12 inside. The surface of the box is covered with sound-absorbing material to absorb the noise generated by the compressor 12. The rear end of the air filter box 9 is connected to the compressor 12. An input pipe 10 is installed at the rear side of the compressor 12. A molecular sieve adsorption tower 7 is installed at the rear end of the input pipe 10.

[0021] refer to Figure 2 The main body is a molecular sieve adsorption tower 7. A solenoid valve 4 is installed at the upper end of the molecular sieve adsorption tower 7, and an attachment plate is provided on the surface of the molecular sieve adsorption tower 7. A buffer spring 5 is installed at the upper end of the attachment plate, and the other end of the buffer spring 5 is assembled on the surface of the attachment plate 6. The attachment plate 6 is assembled on the inner surface of the outer shell 2. When the molecular sieve adsorption tower 7 is working, it generates vibration and is accompanied by a large noise. The installation of the buffer spring 5 can buffer and reduce the vibration generated by the molecular sieve adsorption tower 7, avoid generating a large noise, and protect the internal structure of the device.

[0022] refer to Figure 3 The main body is an outer shell 2. The inner side of the outer shell 2 is equipped with a sound-absorbing surface layer 11, and the lower end of the molecular sieve adsorption tower 7 is equipped with an output pipe 15. A flow meter pipe 16 is equipped on the outer side of the output pipe 15. A drive power supply 14 is installed on the upper end of the pad, and a transmission plate 13 is installed on the upper end of the drive power supply 14. An output port is provided on the other side of the outer shell 2, and the output port is connected to the flow meter pipe 16 through the output pipe 15. A filter layer 8 is installed at the output port.

[0023] In actual use, the device is first installed, and then the drive power supply 14 installed at the bottom is turned on. As the drive power supply 14 is turned on, electrical energy is transmitted to the components installed at the top through the transmission plate 13, which turns on the compressor 12 and the molecular sieve adsorption tower 7, absorbs the outside air and starts to produce oxygen. The air filter box 9 installed at the air inlet filters the incoming air. The sound-absorbing plate at the rear absorbs the noise generated by the compressor 12. The remaining noise is absorbed by the sound-absorbing surface layer 11 provided on the inner surface. The vibration generated by the molecular sieve adsorption tower 7 during operation is reduced by the buffer spring 5. Its noise is prevented from being generated too much by the buffer. Finally, the remaining noise is adsorbed by the adsorption surface layer. Overall, the noise reduction effect is good.
