Description

Technical Field

[0001] This utility model relates to the field of oxygen generator technology, specifically to an oxygen generator noise reduction device. Background Technology

[0002] With the increasing demand for healthcare and quality of life, oxygen concentrators have been widely used in homes, medical institutions, and personal portable applications. Utilizing technologies such as pressure swing adsorption, membrane separation, or water electrolysis, they can continuously or intermittently provide users with high-purity oxygen, playing a significant role in alleviating hypoxia symptoms, assisting respiratory therapy, and improving athletic performance. However, existing oxygen concentrators generally suffer from noise issues during operation, and noise reduction measures on the market are relatively limited. Some products may reduce noise to some extent by optimizing the compressor structure, improving fan blade design, or adding simple vibration damping pads. However, most oxygen concentrators lack sound-absorbing structures at the exhaust outlet, making this exhaust noise particularly noticeable. This can severely impact users' sleep quality and rest, and even cause anxiety or unease for some sound-sensitive users, thus reducing the flexibility of the oxygen concentrator. Utility Model Content

[0003] The purpose of this invention is to provide a noise reduction device for an oxygen generator to solve the problems mentioned in the background art.

[0004] To achieve the above objectives, this utility model provides the following technical solution: an oxygen concentrator noise reduction device, comprising an oxygen concentrator body, a connecting pipe externally connected to the oxygen concentrator body, an exhaust pipe fixedly connected to the bottom end of the connecting pipe, a muffler externally fitted to the exhaust pipe, a fixing ring fixedly connected to the outside of the muffler, a snap-fit ​​structure rotatably connected to the outside of the muffler, the snap-fit ​​structure slidingly connected within the fixing ring, an arc-shaped plate connected to one side of the snap-fit ​​structure, a clamping plate fixedly connected above the arc-shaped plate, a limiting structure connected to the outside of the fixing ring, the limiting structure being connected to the connecting pipe, the snap-fit ​​structure comprising a rotating ring, a cross plate, and bolts, a plurality of guide grooves being formed within the rotating ring, and a guide rod fixedly connected above the cross plate.

[0005] As a further preferred embodiment of this technical solution, the oxygen generator body is externally connected to a pressure gauge, and the clamping plate is clamped to the exhaust pipe.

[0006] As a further preferred embodiment of this technical solution, the rotating ring is rotatably connected to the outside of the muffler, the cross plate is slidably connected to the inside of the fixed ring, and the bolt is connected to the rotating ring.

[0007] As a further preferred embodiment of this technical solution, the rotating ring is connected to the fixed ring by bolts, one side of the cross plate is connected to the arc plate, and the guide rod is slidably connected inside the fixed ring.

[0008] As a further preferred embodiment of this technical solution, the limiting structure includes a limiting plate and a fixing plate, wherein the limiting plate is fixedly connected to the outside of the fixing ring, and the fixing plate is fixedly connected to the outside of the connecting pipe.

[0009] As a further preferred embodiment of this technical solution, a column is fixedly connected above the limiting plate, the column is snapped into the fixed plate, and a limiting plate is fixedly connected outside the column, the limiting plate overlapping the fixed plate.

[0010] This utility model provides a noise reduction device for an oxygen concentrator, which has the following beneficial effects:

[0011] (1) This utility model sets up a muffler, a fixed ring, a snap-fit ​​structure, an arc plate and a snap-fit ​​plate to drive the rotating ring to rotate. When the rotating ring rotates on the surface of the muffler, the guide rod will slide in the guide groove. Then the guide rod will drive the cross plate to move in the fixed ring. The arc plate will drive the snap-fit ​​plate to snap with the exhaust pipe. Subsequently, the rotating ring is locked to the fixed ring by bolts. Through the cooperation between the guide groove, the guide rod and the bolts, the muffler and the exhaust pipe can achieve the function of quick assembly. The muffler makes it easy to muffle the area of ​​the exhaust pipe, avoiding the phenomenon of anxiety or unease caused by noise to sensitive users. It is also easy to replace or repair the muffler separately, thus ensuring the flexibility of the oxygen concentrator.

[0012] (2) By setting a limiting structure, the muffler is fitted onto the surface of the exhaust pipe. The limiting plate on the surface of the muffler will be inserted through the column and the fixing plate. When the limiting plate overlaps with the bottom of the fixing plate, it will drive the rotating ring to rotate, thereby playing a certain positioning role in fixing the muffler and preventing the muffler from shifting its position during installation.

Detailed Implementation

[0018] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention.

[0019] This utility model provides a technical solution: such as Figure 1 and Figure 4 As shown in this embodiment, an oxygen generator noise reduction device includes an oxygen generator body 1, a connecting pipe 2 connected to the outside of the oxygen generator body 1, an exhaust pipe 4 fixedly connected to the bottom end of the connecting pipe 2, a silencer 5 sleeved on the exhaust pipe 4, a fixing ring 6 fixedly connected to the outside of the silencer 5, a snap-fit ​​structure 7 rotatably connected to the outside of the silencer 5, the snap-fit ​​structure 7 slidably connected inside the fixing ring 6, an arc plate 9 connected to one side of the snap-fit ​​structure 7, a snap plate 10 fixedly connected above the arc plate 9, a limiting structure 8 connected to the outside of the fixing ring 6, the limiting structure 8 connected to the connecting pipe 2, and the snap-fit ​​structure 7 including a rotating ring 701, a cross plate 704 and a bolt 703. Several guide grooves 702 are opened in the rotating ring 701, and a guide rod 705 is fixedly connected above the cross plate 704.

[0020] like Figure 1 and Figure 3 As shown, an oxygen concentrator body 1 is externally connected to a pressure gauge 3, a clamping plate 10 is clamped to an exhaust pipe 4, a rotating ring 701 is rotatably connected to the outside of a muffler 5, a cross plate 704 is slidably connected to a fixed ring 6, a bolt 703 is connected to the rotating ring 701, and the rotating ring 701 is connected to the fixed ring 6 through the bolt 703. One side of the cross plate 704 is connected to an arc plate 9, and a guide rod 705 is slidably connected to the fixed ring 6.

[0021] By setting a fixed ring 6, when the rotating ring 701 rotates on the surface of the muffler 5, the guide rod 705 will slide in the guide groove 702. Then the guide rod 705 will drive the cross plate 704 to move within the fixed ring 6, so that the fixed ring 6 plays a certain guiding role in the movement of the cross plate 704, and avoids the cross plate 704 from bumping during the movement.

[0022] like Figure 2 and Figure 4As shown, the limiting structure 8 includes a limiting plate 801 and a fixing plate 802. The limiting plate 801 is fixedly connected to the outside of the fixing ring 6, and the fixing plate 802 is fixedly connected to the outside of the connecting pipe 2. A column 803 is fixedly connected above the limiting plate 801. The column 803 is snapped into the fixing plate 802. A limiting disk 804 is fixedly connected to the outside of the column 803. The limiting disk 804 overlaps with the fixing plate 802.

[0023] By setting the fixing plate 802 and the limiting plate 804, when it is necessary to perform noise reduction treatment on the area of ​​the exhaust pipe 4, the muffler 5 can be fitted onto the surface of the exhaust pipe 4. The limiting plate 801 on the surface of the muffler 5 will be inserted into the fixing plate 802 through the column 803, and the limiting plate 804 will overlap with the bottom of the fixing plate 802, thereby guiding the installation direction of the muffler 5 and preventing misalignment between the muffler 5 and the exhaust pipe 4 during installation.

[0024] This utility model provides a noise reduction device for an oxygen concentrator, the specific working principle of which is as follows:

[0025] When it is necessary to muffle the area of ​​the exhaust pipe 4, the muffler 5 can be fitted onto the surface of the exhaust pipe 4. The limiting plate 801 on the surface of the muffler 5 will be inserted into the fixing plate 802 through the column 803. When the limiting plate 804 overlaps with the bottom of the fixing plate 802, it will drive the rotating ring 701 to rotate. When the rotating ring 701 rotates on the surface of the muffler 5, the guide rod 705 will slide in the guide groove 702. Then the guide rod 705 will drive the cross plate 704 to move in the fixing ring 6. The arc plate 9 will drive the clamping plate 10 to engage with the exhaust pipe 4. Subsequently, the rotating ring 701 will be locked to the fixing ring 6 by the bolt 703.

[0026] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
