Attached Figure Description

[0029] Figure 1 This is a schematic diagram of the structure of a nitrogen generator according to an embodiment of the present invention. Detailed Implementation

[0030] The present invention will be described more clearly and completely below by way of embodiments and in conjunction with the accompanying drawings. The description of the embodiments is for the purpose of helping to understand the present invention, but does not constitute a limitation on the present invention.

[0031] This embodiment provides a nitrogen generating device, including a gas pump and a buffer structure, such as... Figure 1 As shown, the buffer structure includes a square buffer cavity 1, a first pipe 2, and a second pipe 3; the air outlet pipe of the air pump is connected to the first pipe 2 and the second pipe 3 respectively, and both the first pipe 2 and the second pipe 3 are connected to the square buffer cavity 1.

[0032] An air pump is used to draw in external air through the air inlet pipe and discharge the external air in the form of airflow into the first pipe and the second pipe respectively through the air outlet pipe.

[0033] The first pipeline 2 is used to discharge airflow with a pressure greater than the preset airflow pressure into the square buffer chamber;

[0034] The second pipe 3 is used to discharge airflow with a pressure lower than the preset airflow pressure into the square buffer chamber;

[0035] The square buffer chamber 1 is used to uniformly mix airflow with pressure greater than the preset airflow pressure with airflow with pressure less than the preset airflow pressure to obtain uniformly mixed airflow.

[0036] In this embodiment, as Figure 1 As shown, a square buffer cavity 1 is extended at the outlet pipe end of the air pump (e.g., the air outlet pipe of the air pump). The airflow enters the pipe at the outlet pipe end of the air pump and is divided into two airflows. The airflow in the first pipe finally enters the square buffer cavity with a higher pressure (e.g., airflow with a pressure greater than the preset airflow pressure is discharged into the square buffer cavity). The airflow in the second pipe finally enters the square buffer cavity with a lower pressure (e.g., airflow with a pressure less than the preset airflow pressure is discharged into the square buffer cavity). The two airflows converge and are finally mixed evenly in the square buffer cavity, and then enter a single pipe with an average pressure.

[0037] It should be noted that the preset airflow pressure should be set according to the actual situation, and no specific limit is set here.

[0038] In addition, as a fixed power component, the air pump outputs a constant airflow. The airflow flows in the pipeline, and due to the unstable flow pressure, it is easy to cause airflow fluctuations. The nitrogen generation device structure in this embodiment can buffer the airflow pressure and reduce airflow pressure fluctuations.

[0039] The buffer structure in this embodiment can effectively reduce airflow pressure fluctuations, making the airflow run more smoothly, reducing the fluctuation of airflow, and reducing the vibration noise of the nitrogen generator.

[0040] In an alternative embodiment, the first conduit and the second conduit are of different sizes.

[0041] In an optional embodiment, a single pipeline and a nitrogen generator are also included, the single pipeline being connected to a square buffer chamber and the nitrogen generator being connected to the single pipeline;

[0042] A single pipeline is used to discharge the uniformly mixed gas flow from the square buffer chamber into the nitrogen generator;

[0043] A nitrogen generator is used to filter nitrogen from a uniformly mixed gas stream.

[0044] In this embodiment, since the two outlet pipes (e.g., the first pipe and the second pipe) are different in size, the airflow forms a travel difference when it flows through the two pipes (e.g., the first pipe and the second pipe). Specifically, when the airflow flows in the first pipe and the second pipe, the length of the flow is different. The length of the airflow from the previous high pressure point to the next high pressure point is defined as K. When the airflow finally enters the inlet of the square buffer cavity after flowing through the first pipe and the second pipe, the distance of the two airflows forms a travel difference y, y = (w / 2)*K, (w = 1, 3, 5, 7, 9, 11...).

[0045] In an optional embodiment, a muffler is also included;

[0046] A silencer is used to reduce the noise of gas flow in a pipeline.

[0047] In an optional embodiment, a mounting base plate is also included;

[0048] Mounting base plate for securing the air pump.

[0049] In an optional embodiment, a base plate vibration isolation pad is also included;

[0050] The base plate vibration isolation pad is used to reduce the vibration of the air pump.

[0051] In an optional embodiment, a glass cover is also included;

[0052] Glass cover plate, used to seal the mounting base plate.

[0053] In an optional embodiment, the first conduit is connected to the second conduit.

[0054] In an optional embodiment, both the first conduit and the second conduit are arc-shaped.

[0055] In an optional embodiment, a soundproof enclosure is also included;

[0056] Soundproof enclosures are used to reduce the vibration noise of air pumps.

[0057] In the specific implementation process, the air pump draws in external air through the air inlet pipe and discharges the air into the air outlet pipe of the air pump. Then, the air enters the first pipeline and the second pipeline through the air outlet pipe and is divided into two airflows. After passing through the first pipeline and the second pipeline, the airflow enters the square buffer chamber. The pressure is mixed evenly in the square buffer chamber and then flows into the single pipeline at an average pressure (at this time, the airflow pressure in the single pipeline is the average pressure). The airflow at the average pressure flows through the single pipeline and then flows into the nitrogen generator, which generates the nitrogen gas required by the refrigerator.

[0058] This embodiment extends a buffer chamber structure at the outlet of the air pump, allowing the airflow with a pressure greater than the preset airflow pressure flowing through the first pipeline and the airflow with a pressure less than the preset airflow pressure flowing through the second pipeline to be discharged into the square buffer chamber for uniform mixing. This effectively reduces airflow pressure fluctuations, reduces pipeline vibration, and further reduces pipeline airflow noise, thereby reducing the operating vibration noise of the nitrogen generator.

[0059] While specific embodiments of this utility model have been described above, those skilled in the art should understand that these are merely illustrative examples, and the scope of protection of this utility model is defined by the appended claims. Those skilled in the art can make various changes or modifications to these embodiments without departing from the principles and essence of this utility model, but all such changes and modifications fall within the scope of protection of this utility model.
