Therefore, the references to "in one embodiment" or "in an embodiment" appearing throughout the specification do not necessarily refer to the same embodiment.

[0036] First, Figure 1 This is one of the schematic diagrams of a filter adapter assembly and an explosion structure of an embodiment of the utility model. Figure 2 This is the second schematic diagram of a filter adapter assembly and an explosion structure of an embodiment of the utility model. Figure 3 This is a schematic diagram of the external structure of a filter adapter assembly according to an embodiment of the utility model. Figure 4 The utility model is a filter adapter component along the Figure 3 Schematic diagram of the cross-sectional structure in the AA direction, Figure 5 This is a schematic diagram of the assembly of a filter adapter assembly according to an embodiment of the utility model. Figure 6 This is a schematic diagram of the structure of a therapeutic device according to an embodiment of the utility model. Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 5 and Figure 6 The filter adapter assembly is used for filtering and transferring the gas preparation device 5 and the gas consumption device 6, and the filter adapter assembly includes:

[0037] The adapter 1 has a first adapter 11 and a second adapter 12 at both ends thereof, and a filter cavity 13 is provided inside the adapter 1. The first adapter 11 and the second adapter 12 are both connected to the filter cavity 13. The first adapter 11 is connected to the gas preparation device 5, and the second adapter 12 is connected to the gas consumption device 6.

[0038] The oxygen filter element 2 is fixed in the filter cavity 13 .

[0039] It can be seen from the above embodiments that in the embodiment of the utility model, since the first adapter 11 and the second adapter 12 are respectively provided at both ends of the adapter 1, and the adapter 1 has a filter cavity 13 inside, the first adapter 11 and the second adapter 12 are both connected to the filter cavity 13, so the first adapter 11 can be connected to the gas preparation device 5, and the second adapter 12 can be connected to the gas consumption device 6. Since the oxygen filter element is fixed in the filter cavity 13, the gas in the gas consumption device 6 can be filtered twice by the oxygen filter element during the process of inputting the gas into the gas preparation device 5, so that the gas reaching the gas consumption device 6 is cleaner, and the safety of the gas supply of the gas consumption device 6 is further improved. In summary, in the embodiment of the utility model, when there is no flow meter connected between the gas preparation device 5 and the gas consumption device 6, the filter adapter assembly can be used for transfer and filtering, thereby ensuring the cleanliness of the gas reaching the gas consumption device 6.

[0040] In the above embodiments, regarding the structure and material of the adapter 1, the main part of the adapter 1 has a shell structure with an inner cavity, and the material of the adapter 1 can be plastic, aluminum alloy, magnesium alloy, polycarbonate and other materials with relatively stable structures, which is not limited in the embodiments of the present utility model.

[0041] The first adapter 11 and the second adapter 12 are respectively arranged on the two ends of the adapter 1, that is, the first end of the adapter 1 is connected to the first adapter 1, and the second end of the adapter 1 is connected to the second adapter 12. The first end and the second end of the adapter 1 are opposite ends of the adapter 1. The first adapter 11 and the second adapter 12 can be tubular structures. The first adapter 11 and the second adapter 12 need to be connected to the filter cavity 13 inside the adapter 1, that is, the first adapter 11 can provide an air inlet channel for gas to enter the filter cavity 13, and the second adapter 12 can provide an air outlet channel for gas to flow out of the filter cavity 13.

[0042] In addition, the adapter 1 and the oxygen filter element 2 can be an integrally formed structure, or the adapter 1 can be a split structure, which is not limited in the embodiments of the present invention. The oxygen filter element 2 can be one of a sintered filter element, an activated carbon filter element, an electrostatic filter element, a photocatalyst filter element, etc., which is not limited in the embodiments of the present invention. It should be noted that the shape and size of the filter cavity 13 inside the adapter 1 are determined according to the type and shape of the oxygen filter element 2. For example, when the oxygen filter element 2 can be a sintered filter element, the shape of the sintered filter element is cylindrical, and the shape of the filter cavity 13 is a cylindrical cavity.

[0043] Next, the specific structure of the adapter 1 provided in the embodiment of the utility model is specifically introduced:

[0044] In a possible implementation, the adapter 1 and the oxygen filter element 2 are an integrally formed structure.

[0045] In this embodiment, when the manufacturing process and the manufacturing cost are not limited, since the adapter 1 and the oxygen filter element 2 are an integrally formed structure, the sealing of the filter cavity 13 can be fully guaranteed, so that the sealing when filtering the gas through the oxygen filter element 2 in the filter cavity 13 reaches the optimal state, thereby ensuring the filtering effect of the oxygen filter element 2, and at the same time, no gas loss will occur during the process of gas flowing from the first adapter 11 to the second adapter 12.

[0046] In another possible implementation, the adapter 1 is a split structure.

[0047] In this embodiment, the adapter 1 may include at least two split shell structures, which are spliced ​​into a filter cavity 13. In this way, not only does the adapter 1 have lower requirements on the manufacturing process, but it is also convenient to install the oxygen filter element 2 in the filter cavity 13 inside the adapter 1, and when the oxygen filter element 2 needs to be replaced, it is also convenient to disassemble the adapter 1 to replace the oxygen filter element 2, which is conducive to reducing the maintenance and replacement costs of the filter adapter assembly in the later stage.

[0048] In the case where the adapter 1 is a split structure, in some feasible embodiments, it includes a first adapter shell 14 and a second adapter shell 15; the first adapter shell 14 and the second adapter shell 15 are detachably connected, and the first adapter shell 14 and the second adapter shell 15 are connected to form a filter chamber 13; the first adapter joint 11 is arranged on the first adapter shell 14, and the second adapter joint 12 is arranged on the second adapter shell 15.

[0049] It should be noted that, in this embodiment, the shape of the first adapter shell 14 and the shape of the second adapter shell 15 can be a pagoda-shaped shell structure, a prismatic shell structure, a cylindrical shell structure or a shell structure of other shapes, and the embodiment of the utility model does not limit this. In addition, the first adapter shell 14 and the second adapter shell 15 are both shell-shaped structures with one end open, so that the opening of the first adapter shell 14 and the opening of the second adapter shell 15 can be spliced ​​into a filter cavity 13. The first adapter 11 is arranged at the unopened end of the first adapter shell 14 and is connected to the inner cavity of the first adapter shell 14. The second adapter 12 is arranged at the unopened end of the second adapter shell 15 and is connected to the inner cavity of the second adapter shell 15. In this way, since the first adapter shell 14 and the second adapter shell 15 are detachably connected, when installing and removing the oxygen filter element 2, it is only necessary to separate the first adapter shell 14 and the second adapter shell 15 to disassemble the oxygen filter element 2, which is beneficial to reduce the maintenance and replacement cost of the filter adapter assembly in the later stage, and after using it for a period of time, the first adapter shell 14 and the second adapter shell 15 can be disassembled to clean the filter cavity.

[0050] Regarding the specific structure of the above-mentioned adapter 1, in some embodiments, the first adapter housing 14 includes a first connecting ring 141 and a first adapter disk 142, and the second adapter housing 15 includes a second connecting ring 151 and a second adapter disk 152; the first adapter disk 142 is buckled on the first connecting ring 141, so that a first inner cavity is formed between the first adapter disk 142 and the first connecting ring 141, and the second adapter disk 152 is buckled on the second connecting ring 151, so that a second inner cavity is formed between the second adapter disk 152 and the second connecting ring 151; the first adapter disk 142 and the second adapter disk 152 are buckled, so that the first inner cavity and the second inner cavity form a filter cavity 13; the first adapter 11 is arranged on the first adapter disk 142, and the second adapter 12 is arranged on the second adapter disk 152.

[0051] In this embodiment, the first connecting ring 141 and the second connecting ring 151 can be square rings, the first adapter plate 142 and the second adapter plate 152 can be square plates, or the first connecting ring 141 and the second connecting ring 151 can be circular rings, the first adapter plate 142 and the second adapter plate 152 can be circular plates, the first connecting ring 141 and the second connecting ring 151 can also be ring structures of other shapes, the first adapter plate 142 and the second adapter plate 152 can also be disc structures of other shapes, and the embodiments of the utility model are not limited to this. In addition, the shape of the first adapter ring 151 should match the shape of the first adapter disk 142, and the shape of the second connecting ring 151 should match the shape of the second adapter disk 152. For example, when the shape of the first adapter ring 151 is a circular ring, the shape of the first adapter disk 142 is a circular disk (it can also be a circular cover-like structure), and when the shape of the second connecting ring 151 is a circular ring, the shape of the second adapter disk 152 is a circular disk (it can also be a circular cover-like structure). In this way, it is convenient for the first adapter disk 142 to be buckled on the first connecting ring 141 so that a first inner cavity is formed between the first adapter disk 142 and the first connecting ring 141, and the second adapter disk 152 is buckled on the second connecting ring 151 so that a second inner cavity is formed between the second adapter disk 152 and the second connecting ring 151.

[0052] It should be noted that, for the first adapter disk 142 to be buckled on the first connecting ring 141 so that a first inner cavity is formed between the first adapter disk 142 and the first connecting ring 141, it can be understood that the first adapter disk 142 covers the annular surface at one end of the first adapter ring 151, so that the first adapter disk 142 covers the opening at one end of the first adapter ring 151, so that the first adapter disk 142 and the first adapter ring 151 form a shell structure with an open end. For the second adapter disk 152 to be buckled on the second connecting ring 151 so that a second inner cavity is formed between the second adapter disk 152 and the second connecting ring 151, it can be understood that the second adapter disk 152 covers the annular surface at one end of the second connecting ring 151, so that the second adapter disk 152 covers the opening at one end of the second connecting ring 151, so that the second adapter disk 152 and the second connecting ring 151 form a shell structure with an open end. Afterwards, when the first adapter plate and the second adapter plate are buckled together, the first inner cavity and the second inner cavity can form a filter cavity 13. Finally, the first adapter 11 is set on the first adapter plate 142, and the second adapter 12 is set on the second adapter plate 152, so that the first adapter 11 and the second adapter 12 are both connected to the filter cavity 13.

[0053] To sum up, in this embodiment, a pagoda-shaped shell structure is formed between the first adapter 11, the first adapter plate 142 and the first adapter ring 151, and a pagoda-shaped shell structure is formed between the second adapter 12, the second adapter plate 152 and the second adapter ring. Since the joints on the gas preparation device 5 and the gas consumption device 6 that are connected to the external pipeline are also pagoda-shaped joints, it is more convenient to transfer the gas preparation device 5, the gas consumption device 6 and the filter adapter assembly.

[0054] Furthermore, in some embodiments, the first connecting ring 141 and the second connecting ring 151 are detachably connected via a first bolt.

[0055] It should be noted that, in this embodiment, there may be multiple threaded holes on the first connection ring 141, and there may also be multiple threaded holes on the second connection ring 151. Exemplarily, taking the case where the number of threaded holes on the first connection ring 141 is three and the number of threaded holes on the second connection ring 151 is three, the three threaded holes on the first connection ring 141 are evenly distributed (the spacing between each two adjacent threaded holes on the first connection ring 141 is equal), the three threaded holes on the second connection ring 151 are evenly distributed (the spacing between each two adjacent threaded holes on the second connection ring 151 is equal), the three threaded holes on the first connection ring 141 and the three threaded holes on the second connection ring 151 are aligned, and after the first connection ring 141 and the second connection ring 151 are detachably connected by the first bolt, the connection points between the first connection ring 141 and the second connection ring 151 can be evenly distributed, which is more conducive to the tightness of the connection between the first adapter housing 14 and the second adapter housing 15.

[0056] Further, such as Figure 1 and Figure 5 As shown, in some embodiments, the second connecting ring 151 and the main body housing 61 of the gas consumption device 6 are detachably connected by a second bolt 4.

[0057] In this embodiment, the number of threaded holes provided on the second connection ring 151 can be greater than the number of threaded holes provided on the first connection ring 141, that is, some of the threaded holes provided on the second connection ring 151 are aligned with the threaded holes on the first connection ring 141, and the remaining threaded holes on the second connection ring 151 are used to connect with the main body housing 61 of the gas consumption device 6 through the second bolt 4. Exemplarily, taking the number of threaded holes provided on the first connection ring 141 as three and the number of threaded holes provided on the second connection ring 151 as six, the three threaded holes on the first connection ring 141 and the three threaded holes on the second connection ring 151 are aligned, and the remaining three threaded holes on the second connection ring 151 are used to detachably connect with the main body housing 61 of the gas consumption device 6 through the second bolt 4. In this way, the filter adapter assembly and the gas consumption device 6 are convenient to assemble and disassemble, and the structure between the filter adapter assembly and the gas consumption device 6 is made more compact. To summarize, in the above embodiment, a threaded hole is provided on the first connecting ring 141 and a threaded hole is provided on the second connecting ring 151, which not only allows the filter adapter assembly to be assembled on the housing of the ventilation therapy device, but also enables the assembly of the filter adapter assembly itself, so that the filter adapter assembly can be used alone, thereby meeting the assembly requirements of the filter adapter assembly in various application scenarios.

[0058] Optionally, when the adapter 1 includes a first adapter housing 14 and a second adapter housing 15 , in some embodiments, a sealing member 3 is further provided in the filter cavity 13 , and the sealing member 3 is sleeved on the oxygen filter element 2 .

[0059] It should be noted that the shape of the seal 3 is determined according to the shape of the oxygen filter element 2. For example, when the oxygen filter element 2 is cylindrical, the seal 3 is a ring. In this way, when the seal 3 is sleeved on the oxygen filter element 2, the sealing of the filter cavity 13 can be guaranteed, so that the airtightness when filtering gas through the oxygen filter element 2 in the filter cavity 13 reaches the best state, thereby ensuring the filtering effect of the oxygen filter element 2, and at the same time, no gas loss will occur during the process of gas flowing from the first adapter 11 to the second adapter 12.

[0060] Regarding the oxygen filter element 2, in some embodiments, the oxygen filter element 2 is any one of a copper sintered filter element, a stainless steel sintered filter element, and a ceramic sintered filter element.

[0061] It should be noted that the sintered filter element is a new type of filter material with high strength and overall rigidity, which is made of multi-layer metal sintered mesh, multi-layer stainless steel mesh, special lamination pressing, and vacuum sintering. When the sintered filter element is any one of a copper sintered filter element, a stainless steel sintered filter element, and a ceramic sintered filter element, the oxygen filter element 2 can be adapted to application scenarios with higher pressures. In addition, the material of the seal 3 can be a material with a certain sealing effect such as nitrile rubber, polyurethane rubber, polypropylene rubber, silicone rubber, fluororubber, butyl rubber, ethylene propylene rubber, chloroprene rubber, etc., which is not limited in the embodiment of the utility model.

[0062] In some embodiments, the first adapter 11 is connected to the gas preparation device 5 through a first elastic tube, and the second adapter 12 is connected to the gas consumption device 6 through a second elastic tube.

[0063] It should be noted that the first elastic tube and the second elastic tube can be silicone tubes, PVC software tubes, etc. with a certain elastic tubular structure, which makes it easier to connect the first adapter 11 and the gas preparation device 5, and easier to connect the second adapter 12 and the gas consumption device 6.

[0064] In order to solve the problem in the prior art that the gas reaching the gas consumption device is not filtered twice, which makes it difficult to ensure the cleanliness of the gas in the gas consumption device, the first adapter 11 is connected to the gas preparation device 5, and the second adapter 12 is connected to the gas consumption device 6. In this way, in the process of the gas in the gas consumption device 6 being input into the gas preparation device 5, it can be filtered twice by the oxygen filter element, so that the gas reaching the gas consumption device 6 is cleaner, and the safety of the gas supply of the gas consumption device 6 is further improved. In summary, in the embodiment of the utility model, when there is no flow meter connected between the gas preparation device 5 and the gas consumption device 6, the filter adapter assembly can be used for switching and filtering, thereby ensuring the cleanliness of the gas reaching the gas consumption device 6.

[0065] In the second aspect, an embodiment of the utility model provides a ventilation therapy device, which includes a gas preparation device 5 and a gas consumption device 6 and a filter adapter assembly of any embodiment of the first aspect; the gas preparation device 5 and the gas consumption device 6 are connected through the filter adapter assembly, wherein the gas preparation device 5 includes an oxygen cylinder or an oxygen generator, and the gas consumption device 6 includes an oxygen therapy device or a ventilator.

[0066] It should be noted that the beneficial effects of the ventilation therapy device are consistent with the beneficial effects of the filter adapter assembly in the above embodiment, and the embodiments of the present utility model do not limit this.

[0067] The various embodiments in the specification are described in a progressive manner, and each embodiment focuses on the differences from other embodiments. The same or similar parts between the various embodiments can be referenced to each other.
