Description

Technical Field

[0001] This utility model relates to the field of oxygen production equipment technology, specifically to a dustproof device for oxygen production equipment. Background Technology

[0002] An oxygen concentrator is a type of machine that produces oxygen. Its principle is to use air separation technology. First, the air is compressed at 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. The oxygen is then further purified by distillation.

[0003] There are many types of oxygen concentrators on the market, but they generally suffer from poor dust protection. Traditional dust protection methods often involve installing dust filters at the air inlet to separate the air. However, because the dust filters are exposed to the outside air for a long time, their surface easily absorbs a lot of dust, which can lead to blockage and affect the air permeability of the dust filters.

[0004] To address the aforementioned problems, we propose a dust prevention device for oxygen generation equipment. Utility Model Content

[0005] To address the problems in the background art, this utility model provides a dustproof device for oxygen production equipment.

[0006] To achieve the above objectives, the technical solution adopted by this utility model is as follows:

[0007] A dustproof device for an oxygen generator includes a mounting base and a dustproof net installed in the middle of the inner side of the mounting base. A dust cover is provided at the outer end of the mounting base, and an outer plate is provided at the inlet end of the dust cover. A first vent is arranged in a circular array in the middle of the outer plate. A sealing plate is provided on the inner end face of the outer plate, and a second vent is arranged in a circular array in the middle of the sealing plate. A drive motor is provided at the bottom center of the sealing plate. The drive motor drives the sealing plate to rotate, causing the second vent to overlap or intersect with the first vent.

[0008] Preferably, a support ring is provided in the middle of the inner side of the mounting base, a fixing ring is installed on the support ring, and the dustproof net is fixedly installed in the middle of the inner side of the fixing ring.

[0009] Preferably, the support ring has three sets of slots arranged in a triangular pattern on its edge, and the bottom of the fixing ring is provided with three sets of locking blocks corresponding to the three sets of slots. By inserting the locking blocks into the slots, the fixing ring is positioned and installed accordingly.

[0010] Preferably, a triangular support frame is provided in the middle of the inner side of the dust cover, and the drive motor is fixedly installed in the middle of the inner side of the support frame.

[0011] Preferably, the dust cover and the mounting base are connected by threads.

[0012] Preferably, the dustproof net is fixedly installed on the inner middle of the fixing ring by screws.

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

[0014] In this design, the installation base and dust cover allow for quick assembly and disassembly of the dust filter, facilitating its replacement and cleaning. Furthermore, the outer panel and sealing plate allow for the isolation or ventilation of outside air depending on the oxygen generator's operating status. When the oxygen generator is in the open position, the drive motor rotates the sealing plate until the second vent overlaps with the first vent, allowing outside air to enter the oxygen generator sequentially through the first vent, the second vent, and the dust filter. When the oxygen generator is in the open position... When the system stops operating, the drive motor rotates the sealing plate until the second vent is completely offset from the first vent. At this point, the sealing plate covers the first vent, effectively sealing and isolating it from air. This structure allows the dustproof net channel to be opened or closed according to the operating status of the oxygen generator, effectively preventing the dustproof net from being constantly exposed to the outside environment and causing dust to accumulate on its outer surface. This reduces the probability of dust clogging and enhances the effectiveness of the dustproof net. Attached Figure Description

[0020] The technical solution in this application embodiment is to solve the problems mentioned in the background art, and the overall idea is as follows:

[0021] Example: Refer to Figure 1- Figure 4 As shown, a dustproof device for an oxygen generator according to this embodiment includes a mounting base 1 and a dustproof net 10 installed in the middle of the inner side of the mounting base 1; a dustproof cover 2 is provided at the outer end of the mounting base 1, an outer plate 3 is provided at the inlet end of the dustproof cover 2, a first vent 4 is provided in a ring array in the middle of the outer plate 3, a sealing plate 5 is provided on the inner end face of the outer plate 3, a second vent 6 is provided in a ring array in the middle of the sealing plate 5, and a drive motor 7 is provided at the bottom center of the sealing plate 5; the drive motor 7 is used to drive the sealing plate 5 to rotate, so that the second vent 6 and the first vent 4 are in an overlapping or staggered state.

[0022] When the first vent 4 and the second vent 6 are in an overlapping state, the dust cover 2 is in an unobstructed state, and external air can enter the interior of the dust cover 2 through the first vent 4 and the second vent 6 in sequence, allowing external air to enter the interior of the oxygen generator through the dust net 10 for use. When the first vent 4 and the second vent 6 are in a completely staggered state, the sealing plate 5 can cover and seal the first vent 4, thus isolating it from external air and providing a covering and protection function for the dust net 10, preventing the dust net 10 from being constantly exposed to the outside air, which would cause new dust to be adsorbed on the dust net 10 at all times.

[0023] In some examples, a support ring 12 is provided on the inner center of the mounting base 1, and a fixing ring 9 is installed on the support ring 12. The dustproof net 10 is fixedly installed on the inner center of the fixing ring 9.

[0024] In some examples, the edge of the support ring 12 has three sets of slots 13 arranged in a triangle. The bottom of the fixing ring 9 is provided with three sets of blocks 11 corresponding to the three sets of slots 13. By inserting the blocks 11 into the slots 13, the fixing ring 9 is limited and installed, thereby improving the stability of the dustproof net 10 installation.

[0025] In some examples, a triangular support frame 8 is provided in the middle of the inner side of the dust cover 2, and the drive motor 7 is fixedly installed in the middle of the inner side of the support frame 8. The support frame 8 mainly plays a role in stabilizing the drive motor 7 and enhancing the stability of the drive motor 7 installation.

[0026] In some examples, the dust cover 2 is threadedly connected to the mounting base 1, which facilitates the installation and removal of the dust cover 2, allowing staff to quickly remove, clean, or replace the dust net 10.

[0027] In some examples, the dustproof net 10 is fixedly installed on the inner middle of the fixing ring 9 by screws.

[0028] The working principle of this utility model is as follows:

[0029] During use, the mounting base 1 is first fixed to the air inlet of the oxygen generator using screws. Then, the fixing ring 9 with the dust filter 10 is snapped onto the support ring 12, and the clip 11 is inserted into the slot 13 to limit the installation of the dust filter 10. At this time, the dust cover 2 is installed on the outer end of the mounting base 1. The dust cover 2 can press and fix the outer end face of the fixing ring 9, thereby fixing the dust filter 10. Conversely, the dust cover 2 can be removed and the fixing ring 9 can be quickly removed by the staff, which provides convenience for the disassembly, cleaning and replacement of the dust filter 10.

[0030] In addition, by setting an outer plate 3 and a sealing plate 5, when the oxygen generating equipment is running, the drive motor 7 is started, thereby driving the sealing plate 5 to rotate until the second vent 6 and the first vent 4 are in an overlapping state, so that external air will enter the interior of the oxygen generating equipment through the first vent 4, the second vent 6 and the dustproof net 10 in sequence.

[0031] When the oxygen generator stops running, the drive motor 7 drives the sealing plate 5 to rotate until the second vent 6 and the first vent 4 are completely misaligned. At this time, the sealing plate 5 can cover the first vent 4, thus sealing it and preventing outside air from entering the dust cover 2 and adsorbing onto the dust net 10.

[0032] This invention allows for quick disassembly and assembly of the dustproof net 10, facilitating its replacement and cleaning. Furthermore, the outer plate 3 and sealing plate 5 allow for the isolation or opening of channels to allow airflow, depending on the operating status of the oxygen generator. This effectively prevents the dustproof net 10 from being constantly exposed to the outside environment, thus preventing dust from adhering to its outer surface and extending its service life while reducing the probability of dust blockage.

[0033] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of this utility model.
