Description

Technical Field

[0001] The utility model relates to the technical field of nitrogen generators, in particular to a nitrogen generator. Background Art

[0002] A nitrogen generator is a device used to produce high-purity nitrogen, usually used in laboratories, hospitals, pharmaceutical factories and other places. When the nitrogen generator prepares nitrogen, air is generally transported to the nitrogen generator through an air pump, so that the air is separated by the pressure swing adsorption principle at room temperature to produce high-purity nitrogen. When the nitrogen generator is in use, an air pump is installed inside it, and the air pump will generate a lot of heat after working for a long time. In order to avoid damage to the air pump, the heat needs to be discharged. However, during the use of the current nitrogen generator, heat dissipation slots are usually opened on the outer shell of the nitrogen generator at equal distances for heat dissipation. This method makes the internal heat discharge slower, thereby increasing the possibility of damage to the air pump. Therefore, we propose a nitrogen generator to solve the above problem.

Support frames 2 are installed at the openings opened on both sides of the generator body 1, a horizontal plate 3 is fixed inside the right support frame 2, a micro pump 4 is fixed on the top of the horizontal plate 3, a coil 5 is connected and fixed to the water inlet end of the micro pump 4, and a connecting pipe 6 is connected to the water outlet end of the micro pump 4, a water tank 7 is fixed inside the right support frame 2, the bottom end of the coil 5 passes through the water tank 7 and extends to the inside thereof, the bottom end of the connecting pipe 6 is connected and fixed to the top of the water tank 7, a semiconductor refrigeration sheet 8 is fixed to one side wall of the water tank 7, a vertical plate 9 is fixed inside the left support frame 2, and a fan 10 is fixed inside the opening opened by the vertical plate 9, A filter assembly 12 is provided on one side wall of the support frame 2. When the nitrogen generator needs to be cooled internally, the fan 10 can be started, and the external air will enter the interior of the generator body 1 from the other side support frame 2 and then be discharged. At this time, the flow speed of the air inside the generator body 1 can be accelerated, so that the internal heat can be quickly dissipated. In use, the water inside the water tank 7 can be cooled by the semiconductor refrigeration sheet 8, and then the micro pump 4 can be started to pump the water inside the water tank 7 to the inside of the coil 5. Then the water inside the coil 5 can flow back to the inside of the water tank 7 through the connecting pipe 6, and the cycle is repeated. When the external air flows through the coil 5, the coil 5 can be used to exchange heat and cool the air, so as to further quickly dissipate the heat inside the generator body 1.

When in use, when the dust screen 1202 needs to be cleaned, it is only necessary to pull the pull plate 1205 to drive the dust screen 1202 to move, and then it can be pulled out from the inside of the insertion rail 1201 for cleaning.

[0025] like Figure 4As shown, in some embodiments, a limiting frame 13 is fixed inside the support frame 2, and a cotton cloth layer 14 is fixed inside the limiting frame 13. The provided cotton cloth layer 14 can further filter fine impurities in the air, and can play a certain blocking role on moisture in the air entering the generator body 1, thereby preventing the interior of the generator body 1 from getting damp.

[0026] like Figure 1 and Figure 5 As shown, in some embodiments, a first connector 15 is fixedly connected to the top end of the pipeline of the generator body 1, and a second connector 16 is threadedly connected to the first connector 15, so that the pipeline of the generator body 1 is more convenient to connect with the pipeline of other equipment, and the pipelines of the two devices can be more stable after being connected.
