Description

Technical Field

[0001] This utility model relates to the field of oxygen generators, and in particular to an oxygen generator with a convenient replacement of the separation tower structure. Background Technology

[0002] Portable oxygen concentrators are small devices designed for users who need oxygen therapy. With their portability, ease of use, and stability, they provide great convenience to users, especially those who need long-term oxygen therapy or outdoor activities, and can significantly improve their quality of life.

[0003] The separator is a crucial component of portable oxygen concentrators, and its lifespan is affected by various factors, including temperature, humidity, and dust. If the separator is exposed to a humid environment, its performance will decline, resulting in low oxygen flow, low concentration, or even no oxygen output. Therefore, the separator needs to be replaced or maintained regularly. In existing portable oxygen concentrators, the assembly and disassembly of the separator are quite cumbersome, requiring the entire oxygen concentrator to be disassembled to remove the separator. Users typically need to return the entire oxygen concentrator to the manufacturer or repair center for separator replacement or maintenance, leading to a long replacement or maintenance cycle and causing significant inconvenience to users. In addition, if an abnormality is detected in the separator during the manufacturing process, its assembly and disassembly are also very troublesome, affecting production efficiency. Utility Model Content

[0004] The purpose of this invention is to overcome the shortcomings of the prior art and provide an oxygen generator that allows for easy replacement of the separation tower structure.

[0005] According to one aspect of the present invention, an oxygen generator with a conveniently replaceable separation tower structure is provided, comprising:

[0006] The oxygen concentrator body has a recessed accommodating cavity at its bottom.

[0007] A separation tower is inserted into the receiving cavity. The top of the separation tower is equipped with a first oxygen outlet pipe and a second oxygen outlet pipe, which are detachably connected to the oxygen storage tank in the oxygen generator body. The side of the separation tower is equipped with a first air inlet pipe and a second air inlet pipe, which are detachably connected to the air outlet pipe in the oxygen generator body.

[0008] The battery component is located at the bottom of the oxygen concentrator body, covering the separation tower, and is detachably connected to the oxygen concentrator body.

[0009] The oxygen generator of this invention includes a left and right separation tower arranged in parallel. One tower is used for adsorption, and the other for desorption. They work alternately to achieve continuous oxygen supply. A first inlet pipe and a first outlet pipe are located on the left separation tower, and a second inlet pipe and a second outlet pipe are located on the right separation tower. Compressed air generated by the compressor in the generator body enters the separation tower through the outlet pipe and the first inlet pipe, or the outlet pipe and the second inlet pipe. The oxygen separated by the separation tower enters the oxygen storage tank through the first or second outlet pipe. When the separation tower needs to be replaced or maintained... The manufacturer or repair shop only needs to send the new separator to the user. After receiving the new separator, the user first removes the battery components from the oxygen concentrator, then pulls the separator out of the housing, inserts the new separator into the housing, and then reinstalls the battery components on the oxygen concentrator. The installation and removal of the separator are very convenient. The user simply sends the old separator back to the manufacturer or repair shop. The replacement or maintenance of the separator is very convenient. Moreover, if the manufacturer detects any abnormalities in the separator during the production process, the installation and removal of the separator is also very convenient, which can improve production efficiency.

[0010] Furthermore, it also includes a U-shaped handle, with the two free ends of the U-shaped handle hinged to the bottom of the separation tower.

[0011] Therefore, when the separator needs to be removed, simply lift the U-shaped handle from the bottom of the separator and pull the U-shaped handle to easily remove the separator from the cavity on the oxygen generator body. After reinstalling the separator, simply flip the U-shaped lever back onto the bottom of the separator.

[0012] Furthermore, the free ends of both the first and second oxygen outlet pipes are conical, and the first and second oxygen outlet pipes are respectively provided with a first sealing ring and a second sealing ring.

[0013] Therefore, the first and second oxygen outlet pipes, with their free ends in the shape of cones, can be easily inserted into the oxygen storage tank in the oxygen generator body to achieve connection with the oxygen storage tank. When the separation tower needs to be removed, the free ends of the first and second oxygen outlet pipes can be easily separated from the oxygen storage tank in the oxygen generator body. The first sealing ring can improve the sealing performance between the first oxygen outlet pipe and the oxygen storage tank in the oxygen generator body, and the second sealing ring can improve the sealing performance between the second oxygen outlet pipe and the oxygen storage tank in the oxygen generator body.

[0014] Furthermore, it also includes an adapter, which is located in the accommodating cavity. The adapter has two connecting pipes, and the free ends of the first and second oxygen outlet pipes are respectively inserted into the two connecting pipes. The side of the adapter has two insertion pipes, one of which is connected to one connecting pipe and the other is connected to the other connecting pipe. The two insertion pipes are respectively connected to the oxygen storage tank in the oxygen generator body.

[0015] Therefore, the adapter is installed in the accommodating cavity, and the two insertion pipes on the adapter are respectively connected to the oxygen storage tank in the oxygen generator body. When replacing the separation tower, the adapter will not be removed. When the separation tower needs to be removed, the separation tower is pulled out of the accommodating cavity, and the free ends of the first and second oxygen outlet pipes on the separation tower are separated from the connecting pipes on the adapter. When installing the separation tower, when the separation tower is fully inserted into the accommodating cavity, the free ends of the first and second oxygen outlet pipes on the separation tower are respectively inserted into the two connecting pipes on the adapter, thereby realizing the connection between the first and second oxygen outlet pipes and the oxygen storage tank in the oxygen generator body.

[0016] Furthermore, the adapter is fixed to the inner top of the accommodating cavity.

[0017] Therefore, this allows the adapter to be fixed in the cavity of the oxygen generator body, so that the adapter will not be removed when the separation tower is replaced.

[0018] Furthermore, the free ends of both the first and second intake pipes are conical, and the first and second intake pipes are respectively provided with a third sealing ring and a fourth sealing ring.

[0019] Therefore, the first and second air inlet pipes, with their free ends in the shape of cones, can be easily inserted into the air outlet pipe in the oxygen concentrator (a three-way valve is usually installed on the air outlet pipe) to connect to the compressor. When the separation tower needs to be removed, the free ends of the first and second air inlet pipes can be easily separated from the air outlet pipe in the oxygen concentrator. The third sealing ring can improve the sealing between the first air inlet pipe and the air outlet pipe in the oxygen concentrator, and the fourth sealing ring can improve the sealing between the second oxygen outlet pipe and the air outlet pipe in the oxygen concentrator.

[0020] Furthermore, the side of the accommodating cavity is provided with two insertion holes. The air outlet pipe in the oxygen generator body is connected to the two insertion holes through a three-way valve. The free ends of the first air inlet pipe and the second air inlet pipe are respectively inserted into the two insertion holes.

[0021] Therefore, when the separator needs to be removed, it is pulled out of the accommodating cavity, and the free ends of the first and second air inlet pipes on the separator are separated from the two insertion holes on the oxygen concentrator body. When the separator is installed, it is fully inserted into the accommodating cavity, and the free ends of the first and second air inlet pipes on the separator are respectively inserted into the two insertion holes on the oxygen concentrator body, thereby achieving the connection between the first and second air inlet pipes and the air outlet pipe in the oxygen concentrator body.

[0022] Furthermore, it also includes a fixing screw, a protrusion on the side of the port of the accommodating cavity, an internal thread on the protrusion, a fixing hole on the side of the separation tower, and the end of the fixing screw passes through the fixing hole and is screwed into the internal thread on the protrusion.

[0023] Therefore, when the separator needs to be removed, first unscrew the fixing screws. When the separator is fully inserted into the receiving cavity, pass the fixing screws through the fixing holes and tighten them into the internal threads on the protrusion. The fixing screws can make the separator securely installed in the receiving cavity on the oxygen generator body, preventing the separator from shaking in the receiving cavity.

[0024] Furthermore, the bottom of the oxygen concentrator body is provided with insertion slots on both sides, and the top of the battery component is provided with protrusions on both sides that are adapted to the insertion slots. The two protrusions on the battery component are respectively inserted into the two insertion slots.

[0025] Therefore, when it is necessary to disassemble the battery component, simply pull it out horizontally from the bottom of the oxygen concentrator. When installing the battery component, insert the two protruding edges on the battery component into the two insertion slots respectively, and then push the battery component horizontally to the bottom of the oxygen concentrator. The installation and removal of the battery component is also very convenient.

[0026] Furthermore, the bottom of the oxygen concentrator body is provided with a slot, and the top of the battery component is provided with a buckle that matches the slot, and the buckle is inserted into the slot.

[0027] Therefore, when installing the battery component, insert the two protruding edges on the battery component into the two insertion slots respectively. When the battery component is fully pushed to the bottom of the oxygen concentrator body, the buckle on the battery component will be inserted into the slot at the bottom of the oxygen concentrator body, ensuring that the battery component is securely installed at the bottom of the oxygen concentrator body. When it is necessary to remove the battery component, pull the buckle downwards and then pull the battery component out horizontally from the bottom of the oxygen concentrator body.

The first oxygen outlet pipe 21 and the second oxygen outlet pipe 22 are connected to the oxygen storage tank 12 in the oxygen generator body 1 through the adapter 5. The first oxygen outlet pipe 21 and the second oxygen outlet pipe 22 are detachably connected to the oxygen storage tank 12 in the oxygen generator body 1 through the adapter 5. The adapter 5 can be regarded as part of the oxygen storage tank 12 in the oxygen generator body 1. The first oxygen outlet pipe 21 and the second oxygen outlet pipe 22, whose free ends are conical, can be easily inserted into the two connecting pipes 51 on the adapter 5 or into the two connecting pipes 51. When the connecting pipe 51 is separated and the separation tower 2 needs to be removed, the separation tower 2 is pulled out from the accommodating cavity 11. The free ends of the first oxygen outlet pipe 21 and the second oxygen outlet pipe 22 on the separation tower 2 are separated from the connecting pipe 51 on the adapter 5. When installing the separation tower 2, when the separation tower 2 is fully inserted into the accommodating cavity 11, the free ends of the first oxygen outlet pipe 21 and the second oxygen outlet pipe 22 on the separation tower 2 are respectively inserted into the two connecting pipes 51 on the adapter 5, thereby realizing the connection between the first oxygen outlet pipe 21 and the second oxygen outlet pipe 22 and the oxygen storage tank 12 on the oxygen generator body 1.

When the user needs to replace or maintain the separation tower 2, the manufacturer or repair shop can first... The new separator tower 2 is returned to the user. After receiving the new separator tower 2, the user pushes the buckle 32 downwards using the pressing part 321, then pulls the battery component 3 horizontally out from the bottom of the oxygen concentrator body 1, unscrews the fixing screw 6, and then pulls the separator tower 2 out of the receiving cavity 11.
