DETAILED DESCRIPTION

[0022] The technical scheme in the utility model will be further described below in combination with the drawings and embodiments.

[0023] Referring to Figs. 1 to 4The oxygen concentrator noise testing chamber shown includes:

[0024] A testing chamber body 1, wherein an exhaust hole 2 is provided on the top plate 5 or the side plate of the testing chamber body 1;

[0025] An exhaust mechanism is provided, which is fixed in the exhaust port 2 and is located on the top of the test chamber body 1. The exhaust mechanism includes an exhaust pipe 3, an exhaust fan 4 is fixed in the exhaust pipe 3, a sound insulation layer 17 is fixed on the inner wall of the exhaust pipe 3, a first bracket 6 and a second bracket 7 are also fixed in the exhaust pipe 3, and the space between the first bracket 6 and the second bracket is filled with sound insulation material with circulation holes 11. A first bend pipe joint 8 is fixed on the first bracket 6, and a second bend pipe joint 9 is fixed on the second bracket 7. The inner walls of the first bend pipe joint 8 and the second bend pipe joint 9 are both provided with sound insulation layers 17. The upper part of the exhaust pipe 3 has a threaded section and a mounting ring is threadedly connected to it. The mounting ring is fixed to the top plate 5 by screws.

[0026] The oxygen concentrator silent testing chamber of this invention effectively dissipates the heat generated by the oxygen concentrator by setting exhaust holes 2 on the top plate 5 or side plate of the testing chamber body 1. Since the oxygen concentrator generates heat during operation, if this heat cannot be dissipated in time, the internal temperature will continuously rise. This may cause the electronic components and sensors of the oxygen concentrator to malfunction due to overheating, affecting its normal operation and oxygen production efficiency. Therefore, by dissipating heat through the exhaust holes 2, the internal temperature can be controlled within a suitable range, ensuring stable operation of the oxygen concentrator. Connecting two bent pipe joints through the first bracket 6 and the second bracket 7 allows for a longer sound propagation path. During propagation, the sound is gradually absorbed by the sound insulation layer 17 on the inner wall of the exhaust pipe 3, while heat dissipation remains unaffected. Specifically, when the oxygen generator is working, the exhaust fan 4 starts, absorbing heat from the testing chamber. The heat first enters the exhaust pipe 3 and is discharged through the first bend connector 8, then enters the second bend connector 9. The end of the second bend connector 9 discharges the heat to the outside of the testing chamber. At the same time, external noise also enters the exhaust pipe 3, but some of the noise is absorbed by the sound insulation layer 17 on the inner wall of the exhaust pipe 3 and the sound insulation material on the two supports. The other part enters the bend connector and is also absorbed by the sound insulation layer 17 on the bend connector. When installing the exhaust fan 4 of this utility model, a circulation hole 11 is provided on the main body of the exhaust fan 4. While exhausting, it can draw in air from the outside, promoting the balance of air pressure inside and outside the testing chamber. In addition, to facilitate the installation of the exhaust pipe 3, the top of the exhaust pipe 3 has a threaded section, and a mounting ring is threadedly connected to the threaded section. The exhaust pipe 3 is fixed to the top plate 5 by the mounting ring.

[0027] Further, the exhaust pipe 3 is further provided with a sound insulation plug 10 between the first elbow joint 8 and the second elbow joint 9, a plurality of circulation holes 11 are formed in the sound insulation plug 10. Specifically, in order to further enhance the effect of the sound insulation detection chamber to isolate external noise, a sound insulation plug 10 is further provided between the first elbow joint 8 and the second elbow joint 9. Through the arrangement of the sound insulation plug 10, the noise entering the exhaust pipe 3 can be further absorbed. Since a plurality of circulation holes 11 are provided on the sound insulation plug 10, the air circulation between the inside and outside of the detection chamber can be realized, and the oxygen in the sound insulation chamber is sufficient, and the detection personnel will not feel uncomfortable.

[0028] Further, the elbow portion of the first elbow joint 8 and the elbow portion of the second elbow joint 9 are opposite to each other. Specifically, by arranging the elbow portions of the first elbow joint 8 and the second elbow joint 9 to be opposite to each other, the propagation path of the sound can be further increased, and the absorption is more sufficient.

[0029] Further, the exhaust pipe 3 includes a first half pipe 12 and a second half pipe 13 connected by fastening, a horizontal branch pipe 14 is further fixedly connected to the first half pipe 12, a horizontal side pipe 16 is connected to the side of the horizontal branch pipe 14 through a flange 15, and a sound insulation layer 17 is arranged on the inner walls of the horizontal branch pipe 14 and the horizontal side pipe 16. Specifically, in order to facilitate the installation of the first elbow joint 8 and the second elbow joint 9, the exhaust pipe 3 is composed of the first half pipe 12 and the second half pipe 13, which are more convenient to disassemble and assemble. At the same time, the horizontal branch pipe 14 is arranged to increase the propagation path of the sound, which is convenient for absorption.

[0030] Further, the inner walls of the horizontal branch pipe 14 and the horizontal side pipe 16 are further provided with staggered sound insulation sheets 18. Specifically, by connecting the horizontal side pipe 16 to the horizontal branch pipe 14, the overall length of the horizontal branch pipe 14 and the horizontal side pipe 16 is longer, and it is convenient to install sound insulation sheets 18 such as damping sound insulation boards inside, which further absorbs external noise and minimizes external interference during detection in the detection chamber.

[0031] Further, the bottom of the exhaust pipe 3 is connected with a cover plate 19 through screws. Specifically, the bottom of the exhaust pipe 3 is connected with a cover plate 19 through screws. This way makes the bottom of the exhaust pipe 3 in the vertical direction in a sealed state, and the cover plate is also provided with a sound insulation layer 17 to prevent noise from leaking from the bottom, and the exhaust pipe 3 is more firm after assembly.

[0032] Finally, it is explained that the above embodiments are only used to illustrate the technical solutions of the present application and are not limited. Although the present application has been described in detail with reference to the preferred embodiments, it should be understood by those skilled in the art that the technical solutions of the present application can be modified or replaced by equivalents without departing from the purpose and scope of the present application.
