DETAILED DESCRIPTION

[0017] In order to make the technical means for realizing the utility model, creative features, objectives and effects easy to understand, the utility model is further explained below in conjunction with specific diagrams. In the description of the utility model, it should be noted that, unless otherwise clearly stipulated and limited, the terms "installation", "connection" and "connection" should be understood in a broad sense. For example, it can be a fixed connection, a detachable connection, an integral connection or a mechanical connection, or an electrical connection; it can be a direct connection, or an indirect connection through an intermediate medium, or it can be internal communication between two components.

[0018] Example 1

[0019] like Figure 1-2 An oxygen concentrator for convenient filter replacement shown in the figure comprises an oxygen concentrator body 1, a control panel 2, a support plate 3, a sliding plate 4 and a filter assembly, the control panel 2 is connected to one side of the oxygen concentrator body 1, the control panel 2 is used to operate the operation of the oxygen concentrator body 1, the support plate 3 is connected to one side of the oxygen concentrator body 1, a slide groove 6 is provided at the bottom of the support plate 3, the sliding plate 4 is slidably connected to the slide groove 6, the support plate 3 is "L"-shaped, the sliding plate 4 is "T"-shaped, one end of the support plate 3 is arranged parallel to the sliding plate 4 to limit the sliding plate 4 to prevent the sliding plate 4 from sliding out of the slide groove 6, a sliding block is provided at the bottom of the sliding plate 4, the sliding plate 4 is slidably connected to the slide groove 6 through the sliding block, and an automatic replacement assembly for automatically replacing the filter assembly is provided on one side of the sliding plate 4, and there are multiple filter assemblies installed on the automatic replacement assembly.

[0020] In this embodiment, the automatic replacement component includes a telescopic device 5, a motor 7, a turntable 8 and a rotating shaft 12. The fixed end of the telescopic device 5 is connected to the oxygen generator body 1. The telescopic device 5 can adopt an electric push rod. The telescopic end of the telescopic device 5 is connected to the two ends of the sliding plate 4. Starting the telescopic device 5 can push the sliding plate 4 to move in the slide groove 6 to change the distance between the filter assembly and the oxygen generator body 1. The fixed end of the motor 7 is connected to the sliding plate 4, and the output end of the motor 7 is connected to the rotating shaft 12. The rotating shaft 12 is connected to the turntable 8. Multiple filter assemblies can be detachably connected to the turntable 8. When replacing the filter assembly, it is only necessary to start the motor 7 to drive the rotating shaft 12 to rotate, and the turntable 8 will rotate accordingly, so that the filter assembly rotates along the rotating shaft 12, so that the position of the filter assembly is changed, and the filter assembly can be replaced without manual replacement, thereby achieving the effect of improving work efficiency.

[0021] It should be noted that a plurality of through holes 11 are provided on the turntable 8, each through hole 11 is correspondingly provided with a sealing cover 9, and each through hole 11 corresponds to each filter assembly one by one. When the oxygen concentrator body 1 is used, the sealing cover 9 needs to be opened to allow the interior of the filter assembly to circulate with air, so that air can enter the filter assembly. Closing the sealing cover 9 when not in use can reduce the contact time between the filter assembly and the air, and can increase the service life of the filter assembly.

[0022] Example 2

[0023] A further improvement on the basis of Example 1 is that Figure 3-4 An oxygen concentrator with convenient filter replacement is shown. The filter assembly includes a filter housing 10, a filter frame 15 and a humidity detector 17. The filter housing 10 is installed on a turntable 8. The filter frame 15 is detachably connected to the inner wall of the filter housing 10. The detachable filter frame 15 can facilitate the replacement of the filter frame 15 and the adsorbent 16. The filter frame 15 is provided with an adsorbent 16 inside. The adsorbent 16 can be a mixture of absorbent cotton and activated carbon, etc., to adsorb impurities and moisture in the air. The fixed end of the humidity detector 17 is connected to the inner wall of the filter housing 10, and the detection end of the humidity detector 17 extends into the adsorbent 16. The humidity detector 17 is connected to the control panel 2. The humidity detector 17 can monitor the humidity of the adsorbent 16 in real time. When the humidity reaches a threshold value, the humidity detector 17 transmits a signal to the control panel 2, and the control panel 2 controls the telescopic device 5 and the motor 7 to complete the replacement of the filter assembly, so that the effect of the filter assembly is always in the best state, which can effectively improve the filtration rate.

[0024] Furthermore, it also includes a sealing ring 13. An air inlet 14 is opened on one side of the oxygen concentrator body 1, and an air outlet 18 is opened on the other side of the oxygen concentrator body 1. The sealing ring 13 is arranged on the outside of the air inlet 14. The outer wall of the sealing ring 13 is tightly fitted to the inner wall of the filter assembly 10. When one end of the filter 10 is tightly attached to the oxygen concentrator body 1, the sealing ring 13 can improve the sealing of the filter assembly and improve the filtering effect of the filter assembly.

[0025] The process flow and working principle of the utility model are as follows: when the oxygen generator body 1 is used, the humidity of the adsorbent 16 is monitored in real time through the humidity detector 17. When the humidity of the adsorbent 16 reaches the threshold value, the humidity detector 17 feeds back a signal to the control panel 2, and the control panel 2 controls the operation of the motor 7 and the telescopic device 5. The telescopic device 5 pushes the sliding plate 4 away from the oxygen generator body 1, and then the motor 7 is started to drive the rotating shaft 12 to rotate. The turntable 8 rotates with the filter assembly, so that the filter assembly that reaches the threshold value rotates to other angles, so that the unused filter assembly is aligned with the air inlet 14, and then the telescopic device 5 pushes the sliding plate 4 to make the inner wall of the filter housing 10 fit closely with the outer wall of the sealing ring 13, and the sealing cover 9 is opened. At this time, the air can be filtered by the new filter assembly without manual replacement. Compared with the prior art, it has the effect of improving work efficiency and improving filtration rate.
