DETAILED DESCRIPTION

[0026] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0027] The purpose of the present invention is to provide a new type of medical oxygen concentrator to solve the problems existing in the above-mentioned prior art, and to be able to humidify the output oxygen in advance, thereby improving the user's comfort.

[0028] In order to make the above-mentioned objects, features and advantages of the present invention more obvious and easy to understand, the present invention is further described in detail below with reference to the accompanying drawings and specific embodiments.

[0029] like Figure 1-Figure 3As shown, this embodiment provides a new type of medical oxygen concentrator, including an oxygen concentrator housing 1, an air inlet pipe 8 is provided on the lower side wall of the oxygen concentrator housing 1, and a disassembly filter 9 can be detachably connected to the air inlet pipe 8, and the disassembly filter 9 is used to perform the first coarse filtration of the incoming air. The air inlet pipe 8 is connected to a delivery pipe at one end inside the oxygen concentrator housing 1, and an air compressor 10 and a molecular sieve 14 are provided on the delivery pipe. The air compressor 10 is closer to the air inlet pipe 8 than the molecular sieve 14. The air compressor 10 provides power for gas delivery, thereby sucking in the outside air, and the molecular sieve 14 is further finely filtered and absorbs nitrogen in the air, and the molecular sieve 14 can be pre-filled in the molecular sieve 14 cylinder or the molecular sieve 14 adsorption tower. The delivery pipe is connected to a water storage tank 15 at one end away from the air inlet pipe 8, and one end of the delivery pipe extends into the bottom of the water storage tank 15, so that all the gas filtered by the molecular sieve 14 enters the water. The top of the water storage tank 15 is a conical structure with a small top and a large bottom so that oxygen can be gathered together. The top of the water storage tank 15 is connected to an oxygen output pipe, and one end of the oxygen output pipe away from the water storage tank 15 is located on the outer wall of the oxygen generator housing 1. Finally, the oxygen gathered at the top of the water storage tank 15 is discharged to the outside through the oxygen output pipe. In addition, in order to facilitate the connection, a related joint can be installed at the outer end of the oxygen delivery pipe to facilitate the connection of external components. In addition, a control panel can also be set on the outer wall of the oxygen generator housing 1, and the air compressor 10 can also be electrically connected to the control panel, and the operation of the equipment is controlled by the control panel. Furthermore, a flow sensor is installed on the oxygen output pipe, and the flow sensor is electrically connected to the control panel, so that the control panel can display the value detected by the flow sensor.

[0030] In actual use, the air compressor 10 is started through the control panel, and the air compressor 10 sucks in the external gas. The gas passes through the disassembled filter 9 at the air inlet pipe 8 for the first coarse filtration, thereby removing most of the impurities in the air. Then the gas passes through the molecular sieve 14 on the delivery pipe for fine filtration to remove nitrogen in the air. Then the gas will enter the water in the water storage tank 15. One of the reasons for entering the water is to further purify the air, and the other is to humidify the oxygen. Then the oxygen overflowing from the water will continue to flow upward, gather at the top of the water storage tank 15, and finally be discharged through the oxygen output pipe.

[0031] In this embodiment, a sound absorbing layer 16 is provided inside the water storage tank 15. The sound absorbing layer 16 is made of a hard sponge that is not easily deformed by water. The sound absorbing layer 16 is located on the water surface in the water storage tank 15. The purpose of providing the sound absorbing layer 16 is that when oxygen is introduced into the water, bubbles may be generated on the water surface, thereby making noise, and the sponge can effectively avoid this problem.

[0032] In this embodiment, a water inlet pipe 18 and a water outlet pipe 19 are provided on the side wall of the water storage tank 15. A water pump is provided on the water inlet pipe 18, and the water pump is electrically connected to the control panel. The end of the water inlet pipe 18 away from the water storage tank 15 is connected to a water source, which can be a container capable of storing water, such as a water tank or a water bottle. When the water in the water storage tank 15 is used or used for a period of time, the water in the water storage tank 15 will gradually decrease. At this time, the water pump is started through the control panel to replenish water in the water storage tank 15 in time.

[0033] Furthermore, a liquid level sensor is provided in the water storage tank 15 , and the liquid level sensor is also electrically connected to the control panel for real-time monitoring of the water level in the water storage tank 15 .

[0034] A water valve is provided on the water outlet pipe 19, and the water valve is an electric control valve and is electrically connected to the control panel. Normally, the water valve is in a closed state. If the device is not used for a long time, the water valve can be opened to release the water in the water storage bin 15 to avoid the water in the water storage bin 15 from being stored for a long time.

[0035] In this embodiment, if Figure 2 As shown, the delivery pipe is provided with a first valve 11, a spiral tube 12 and a second valve 13 in sequence, and the first valve 11, the spiral tube 12 and the second valve 13 are all arranged between the air compressor 10 and the molecular sieve 14. The first valve 11 and the second valve 13 are electrically controlled valves, and the first valve 11 and the second valve 13 are both electrically connected to the control panel, and the first valve 11 and the second valve 13 are usually in an open state. The spiral tube 12 is provided to increase the gas path, and the dust or impurities in the gas can be further thrown onto the inner wall of the spiral tube 12 for accumulation by centrifugal separation.

[0036] As time goes by, the impurities in the spiral tube 12 will increase, so it needs to be back-blown. For this purpose, the end of the spiral tube 12 near the first valve 11 is connected to the dust collecting container 20 through the dust collecting pipe, and the end of the spiral tube 12 near the second valve 13 is connected to the back-blowing blower 21 through the back-blowing pipe, and the back-blowing blower 21 is electrically connected to the control panel. When back-blowing is required, the first valve 11 and the second valve 13 are closed and the back-blowing blower 21 is opened through the control panel, and the back-blowing blower 21 blows air into the spiral tube 12 in the reverse direction, so that the impurities accumulated in the spiral tube 12 are blown toward the dust collecting container 20, so as to clean the spiral tube 12, and the blown dust is finally collected in the dust collecting container 20.

[0037] In this embodiment, a horizontal partition is provided in the oxygen generator housing 1, and an equipment compartment is provided below the partition. The dust collection container 20 and the blower 21 are both provided in the equipment compartment. A hatch 7 is provided on the side wall of the equipment compartment. At regular intervals, the staff can open the hatch 7 and clean the dust collection container 20.

[0038] In this embodiment, a flow stabilizing structure is provided on the oxygen output pipe, and the flow stabilizing structure includes a plurality of flow stabilizing channels 17 arranged in parallel with each other. When the gas passes through, the gas can flow evenly into the plurality of flow stabilizing channels 17. The purpose of such arrangement is to distribute the gas evenly, and the gas can reduce the gas flow rate when the gas flows into the rear oxygen output pipe after passing through the flow stabilizing channels 17, so that the gas is gently delivered to the user.

[0039] In this embodiment, if Figure 3 As shown, the side wall of the air inlet pipe 8 is evenly distributed with a plurality of L-shaped snap-in grooves on the circumference, specifically three of them, and the further snap-in grooves include an axial groove and a circumferential groove, and the axial groove and the circumferential groove are arranged perpendicularly. Correspondingly, the outer circumference of the disassembly filter 9 is evenly distributed with a plurality of snap-in blocks, specifically three of them. In actual use, each snap-in block on the disassembly filter 9 is first pushed in along the axial groove of the snap-in groove, and when it is lifted to the junction of the axial groove and the circumferential groove, the disassembly filter 9 is rotated so that the snap-in block moves to the circumferential groove, so that the snap-in groove and the snap-in block are snapped. If the disassembly filter 9 needs to be disassembled and replaced with a new one, it can be taken out by simply twisting the disassembly filter 9 in the opposite direction.

[0040] In this embodiment, if Figure 1 As shown, the lower end of the oxygen generator housing 1 can be connected to a mobile base 2, the top of the mobile base 2 is provided with a groove that matches the bottom of the oxygen generator housing 1, and the lower end of the mobile base 2 is provided with a plurality of universal wheels 4, which is convenient for the staff to push it. And preferably, the universal wheels 4 with built-in brakes are used, and the brakes can be pressed when moving to the expected position, thereby preventing the oxygen generator housing 1 from moving by itself.

[0041] In this embodiment, the outer side wall of the oxygen generator case 1 is provided with a plurality of docking blocks 3, and the upper end of the mobile base 2 is provided with a plurality of docking slots. The docking blocks 3 are the same in number as the docking slots and their positions correspond one to one. Specifically, two docking blocks 3 can be provided, and each docking block 3 can be respectively plugged into the corresponding docking slot, thereby realizing the rapid positioning of the oxygen generator case 1.

[0042] In this embodiment, an auxiliary shoulder strap 6 and a lifting handle 5 are provided on the oxygen generator case 1. The auxiliary shoulder strap 6 and the lifting handle 5 are provided to assist in carrying when the mobile base 2 is not used. The auxiliary shoulder strap 6 can facilitate the staff to carry the oxygen generator case 1, and the lifting handle 5 is convenient for the staff to lift it.

The above examples are only used to help understand the method and core ideas of the present invention. At the same time, for those skilled in the art, according to the ideas of the present invention, there will be changes in the specific implementation methods and application scope. In summary, the content of this specification should not be understood as limiting the present invention.
