Description

Technical Field

[0001] The utility model relates to the technical field of oxygen concentrators, in particular to a heat dissipation mechanism of an oxygen concentrator. Background Art

[0002] Oxygen generator is a type of machine that produces oxygen. Its principle is to use air separation technology. First, the air is compressed at a high density, and then the different condensation points of the components in the air are used to separate the gas and liquid at a certain temperature, and then distilled to separate it into oxygen and nitrogen.

[0003] In order to prevent the temperature inside the existing oxygen concentrator from being too high when in use, heat dissipation holes are opened on the surface of the oxygen concentrator for heat dissipation. However, the efficiency of a single heat dissipation hole is low, and the internal part of the oxygen concentrator is prone to overheating when the oxygen concentrator is used for a long time. Therefore, we propose a heat dissipation mechanism for an oxygen concentrator to solve the above problem. Utility Model Content

[0004] The utility model aims to solve the shortcomings in the prior art and proposes a heat dissipation mechanism for an oxygen concentrator.

[0007] Preferably, the filtering mechanism includes a fixed outer frame, the back side of the oxygen generator body is fixedly connected with the fixed outer frame, and the inner wall of the fixed outer frame is fixedly connected with a partition baffle, and the outer sides of the fixed outer frame and the partition baffle are installed with a filter screen plate by installing bolts, and the filter screen plate can be easily installed by installing bolts.

[0008] Preferably, the internal space of the fixed outer frame is divided into two by a partition baffle, and the two spaces are respectively adapted to the surface dimensions of the heat dissipation holes and the ventilation fan. The partition baffle can conveniently separate the heat dissipation holes and the ventilation fan to prevent the ventilation fan from drawing in hot air.

[0009] Preferably, the driving mechanism includes a mounting rod, the top of the fixed outer frame is fixedly connected with the mounting rod, and the top of the mounting rod is fixedly connected with a fixing sleeve, a pushing air pump is inserted inside the fixing sleeve, and the mounting rod is threadedly connected to the fixed outer frame, which can facilitate later disassembly and maintenance.

[0010] Preferably, the shielding mechanism includes a dust shield outer plate, the dust shield outer plate is fixedly connected to the bottom of the push air pump, and connecting columns are fixedly connected to both sides of the top of the dust shield outer plate, and a limiting slider is fixedly connected to the inner side of the end of the connecting column, so that the outer end of the fixed outer frame can be conveniently covered and shielded by the dust shield outer plate.

[0011] Preferably, the cross section of the connecting column is set to be L-shaped, and sliding grooves compatible with the limiting slider are opened on both sides of the fixed outer frame. By setting the cross section of the connecting column to be L-shaped, the limiting slider can be easily installed.

[0012] Preferably, the cleaning mechanism includes a fixed frame, which is fixedly connected to the upper outer side of the dust shield outer plate, and the inner wall of the fixed frame is welded to one end of a push spring, the other end of the push spring is welded to one side of a driving cross bar, and the other side of the driving cross bar is fixedly connected to a cleaning brush head, and the driving cross bar can be conveniently telescopically moved inside the fixed frame through the fixed frame, so that the driving cross bar can drive the cleaning brush head to clean the surface of the mounting bolt.

[0013] Compared with the prior art, the beneficial effects of the utility model are:

[0014] 1. The device can conveniently discharge the hot air inside the oxygen concentrator body through the heat dissipation holes, and can blow the outside air into the oxygen concentrator body through the ventilation fan, thereby increasing the heat dissipation effect of the oxygen concentrator body. At the same time, the filter screen installed inside the fixed outer frame can be used to filter the dust in the outside air. When the oxygen concentrator body is not working, the shielding mechanism can cover the surface of the fixed outer frame, thereby effectively preventing dust from entering and accumulating in the oxygen concentrator body.

[0015] 2. The device can conveniently install the push air pump above the fixed outer frame through the mounting rod, so as to control the opening and closing of the shielding mechanism as a whole. During the movement of the shielding mechanism, the driving cross bar can drive the cleaning brush head to move along the surface of the filter screen plate, so as to facilitate the scraping of the filtered matter on the surface of the filter screen plate to avoid affecting the filtering effect of the filter screen plate. At the same time, through the elastic force of the pushing spring itself, the driving cross bar can conveniently drive the cleaning brush head to keep in contact with the filter screen plate.

[0027] Further, see Figure 2 and Figure 3 It can be known that the filtering mechanism 4 includes a fixed outer frame 41, the back of the oxygen generator body 1 is fixedly connected with the fixed outer frame 41, and the inner wall of the fixed outer frame 41 is fixedly connected with a partition baffle 42, and the outer sides of the fixed outer frame 41 and the partition baffle 42 are installed with a filter screen 44 through mounting bolts 43, and the filter screen 44 can be conveniently installed in the fixed outer frame 41 by threading the mounting bolts 43 with the partition baffle 42.

[0028] Further, see Figure 2 and Figure 3It can be known that the internal space of the fixed outer frame 41 is divided into two by the partition baffle 42, and the two spaces are respectively adapted to the surface dimensions of the heat dissipation hole 2 and the ventilation fan 3. The partition baffle 42 is used to conveniently divide the internal space of the fixed outer frame 41, thereby preventing the ventilation fan 3 from drawing in hot air.

[0029] Further, see Figure 2 and Figure 3 It can be known that the driving mechanism 5 includes a mounting rod 51, the mounting rod 51 is fixedly connected to the top of the fixed outer frame 41, and the top of the mounting rod 51 is fixedly connected to a fixing sleeve 52, and a pushing air pump 53 is inserted into the interior of the fixing sleeve 52. By setting the cross-section of the mounting rod 51 to be L-shaped, the function of limiting the installation of the pushing air pump 53 can be facilitated.

[0030] Further, see Figure 3 and Figure 4 It can be known that the shielding mechanism 6 includes a dust shield outer plate 61, and the dust shield outer plate 61 is fixedly connected to the bottom of the push air pump 53, and connecting columns 62 are fixedly connected to both sides of the top of the dust shield outer plate 61, and the inner side of the end of the connecting column 62 is fixedly connected to a limiting slider 63.

[0031] Further, see Figure 3 and Figure 4 It can be known that the cross-section of the connecting column 62 is set to be L-shaped, and sliding grooves compatible with the limiting slider 63 are opened on both sides of the fixed outer frame 41. The limiting slider 63 is driven to move by the connecting column 62, and the limiting slider 63 can slide along the sliding groove, thereby playing the role of limiting and guiding the movement of the dust shield outer plate 61.

When the oxygen generator body 1 is not in use, the dust shield outer plate 61 can drive the connecting column 62 and the limit slider 63 to move along the surface of the fixed outer frame 41 by pushing the air pump 53. When the shielding mechanism 6 covers the surface of the fixed outer frame 41, the filter screen plate 44 can be conveniently shielded and protected to avoid dust collection. At the same time, through the movement of the dust shield outer plate 61, the driving cross bar 73 can drive the cleaning brush head 74 to move along the surface of the filter screen plate 44, so as to facilitate the scraping of the filtered matter on the surface of the filter screen plate 44, and the driving cross bar 73 can be conveniently pushed by the pushing spring 72;
