[0003] In the existing portable oxygen generator, the top of the compressor cover for covering the compressor is provided with an exhaust fan, which can blow out the hot air generated by the compressor working in the compressor cover and the nitrogen discharged by the separation tower through the exhaust hole on the base of the oxygen generator. Since the hot air in the compressor cover and the nitrogen discharged by the separation tower are blown out from different directions by the exhaust fan, it is easy to cause backflow of hot air and nitrogen, i.e. part of the hot air and nitrogen will flow back into the compressor cover, resulting in unsmooth exhaust, which can easily affect the working efficiency of the oxygen generator. Moreover, the noise generated by the compressor is directly discharged through the exhaust hole, increasing the overall noise level of the oxygen generator. SUMMARY

[0011] Further, the two sides of the horizontal plate are respectively provided with a left abutting step and a right abutting step, and the left abutting step and the right abutting step are respectively connected with the two ends of the abutting step.

[0012] Therefore, the horizontal plate can be stably buckled on the base of the oxygen generator through the left abutting step, the abutting step and the right abutting step.

[0013] Further, the horizontal plate and the vertical plate are integrally formed.

[0014] Therefore, the integrally molded horizontal and vertical plates can ensure the overall strength of the exhaust structure.

The reinforcing rib 22 is integrally formed with the vertical plate 2, which can further improve the strength between the horizontal plate 1 and the vertical plate 2.

[0035] See Figures 1 to 3 A cavity 3 is formed at the junction of the horizontal plate 1 and the vertical plate 2. A fixing hole 31 is formed in the cavity 3. A receiving cavity 32 is formed on the outer bottom of the cavity 3. One end of the fixing hole 31 is located on the inner bottom of the cavity 3. Figure 2 As shown), the other end of the fixing hole 31 is located on the top of the receiving cavity 32. Figure 3 As shown), the outer wall 33 of the cavity 3 is located below the horizontal plate 1. Figure 1 As shown, when the exhaust structure is installed on the base of the oxygen concentrator, the base of the oxygen concentrator is provided with a mounting protrusion. The mounting protrusion on the base of the oxygen concentrator is inserted into the receiving cavity 32 on the bottom of the outer cavity 3. Then, a screw is passed through the fixing hole 31 in the cavity 3 and screwed onto the mounting protrusion on the base of the oxygen concentrator. The receiving cavity 32 can play a positioning role, so that the exhaust structure of this utility model can be quickly installed in the compressor cover of the oxygen concentrator.

[0036] See Figures 1 to 3 An obstacle avoidance cavity 4 is formed at the junction of the horizontal plate 1 and the vertical plate 2. The obstacle avoidance cavity 4 is used to avoid the compressor in the compressor cover of the oxygen generator. When the exhaust structure is installed in the compressor cover of the oxygen generator, the obstacle avoidance cavity 4 can prevent the compressor in the compressor cover from interfering with the horizontal plate 1 and the vertical plate 2.

[0037] See Figures 4 to 7The exhaust structure of this utility model is installed in the compressor cover 6 of the oxygen concentrator. The oxygen concentrator base 5 is provided with a mounting protrusion 51 and an exhaust hole 52 adapted to the exhaust structure. The oxygen concentrator base 5 is also provided with a stepped portion 53 adapted to the exhaust structure. The compressor 7 is installed on the oxygen concentrator base 5. The compressor cover 6 is installed on the oxygen concentrator base 5 and covers the outside of the compressor 7. An exhaust fan 8 is installed on the top of the compressor cover 6. The separation tower of the oxygen concentrator is discharged through the nitrogen discharge port 9. When installing the exhaust structure of this utility model, the mounting protrusion 51 on the oxygen concentrator base 5 is inserted into the receiving cavity 32 on the bottom of the concave cavity 3. Figure 3 As shown), the end of the horizontal plate 1 with the pressure step 11 is pressed upward against the bottom of the side wall of the compressor cover 6. The left pressure step 12, pressure step 11, and right pressure step 13 on the horizontal plate 1 are snapped downward onto the step portion 53 on the oxygen concentrator base 5. The pressure protrusion 21 at the bottom of the vertical plate 2 is pressed downward against the oxygen concentrator base 5. Then, screws are used to pass through the fixing hole 31 in the cavity 3. Figure 2 (As shown) and screwed onto the mounting protrusion on the oxygen concentrator base 5, the exhaust structure is securely installed in the compressor cover 5 and the longitudinal plate 2 is directly opposite the exhaust port 52 on the oxygen concentrator base 5. Figure 6 (As shown); During the operation of the oxygen concentrator, the horizontal plate 1 and the vertical plate 2 can prevent the hot air generated by the compressor 7 in the compressor housing 6 and the nitrogen discharged from the nitrogen discharge port 9 from being directly discharged through the exhaust port 52 from different directions, causing the hot air and nitrogen to flow back. When the exhaust fan 8 blows air into the interior of the compressor housing 6, the horizontal plate 1 and the vertical plate 2 can guide the hot air in the compressor housing 6 and the nitrogen discharged from the nitrogen discharge port 9 into the area enclosed by the horizontal plate 1, the vertical plate 2 and the oxygen concentrator base 5 through the left air duct 10 and the right air duct 20 on both sides of the compressor 7. The hot air and nitrogen enter the area enclosed by the horizontal plate 1, the vertical plate 2 and the oxygen concentrator base 5 in the left air duct 10 in sequence along the A direction and the B direction. The air enters the area enclosed by the horizontal plate 1, the vertical plate 2, and the oxygen generator base 5 in the right air duct 20 along the C and D directions, and is finally discharged through the exhaust port 52. Moreover, the horizontal plate 1 and the vertical plate 2 can also block the noise generated by the compressor 7, preventing the noise generated by the compressor 7 from being directly discharged through the exhaust port 52, effectively reducing the amount of noise generated by the compressor 7. The exhaust structure of this utility model can not only effectively reduce the noise generated by the compressor 7, but also guide the hot air in the compressor cover 6 and the nitrogen discharged from the nitrogen outlet 9 to flow smoothly from the left air duct 10 and the right air duct 20 on both sides of the compressor 7 to the exhaust port 52 and be discharged through the exhaust port 52, thereby improving the working efficiency of the oxygen generator and reducing the overall noise level of the oxygen generator.
