Description

Technical Field

[0001] The utility model relates to the field of oxygen concentrators, in particular to an oxygen concentrator and an oxygen concentrator comprising the same. Background Art

[0002] Oxygen concentrators are widely used in homes, hospitals, sanatoriums, schools, hotels, sports venues, bars, oxygen bars, and plateau military stations. As people's awareness of health increases, the market for home oxygen concentrators has gradually emerged and become an important health care device. As a home medical device, its market demand continues to grow with people's pursuit of a healthy life.

[0003] The oxygen humidifier cup in the oxygen concentrator is an important accessory in the oxygen concentrator. Its main function is to humidify the oxygen produced by the oxygen concentrator so that the oxygen becomes moist before inhalation and reduces discomfort to the respiratory tract.

[0004] In the existing oxygen concentrator, the oxygen humidification cup is separated from the oxygen supply pipe outside the oxygen concentrator. The oxygen humidification cup returns the humidified oxygen to the pipe inside the oxygen concentrator body and outputs it from the oxygen outlet on the oxygen concentrator body. The oxygen supply pipe is installed on the oxygen outlet on the oxygen concentrator body. In this way, the humidity of the oxygen humidified by the oxygen humidification cup decreases after passing through the pipe inside the oxygen concentrator body. For example, water vapor will condense on the inner wall of the pipe inside the oxygen concentrator body, resulting in the humidity of the oxygen finally entering the oxygen supply pipe cannot be guaranteed. In addition, in the existing oxygen concentrator, the oxygen humidification cup and the oxygen concentrator body are usually detachably connected, but the connection structure is usually complicated. Some of them require disassembly of some connecting pipes before the oxygen humidification cup can be removed from the oxygen concentrator body, which is inconvenient to operate. Utility Model Content

[0005] The purpose of this utility model is to overcome the above-mentioned deficiencies in the prior art and provide an oxygen concentrator.

[0006] According to one aspect of the present invention, an oxygen concentrator is provided, comprising an oxygen concentrator body and an oxygen humidification cup.

[0007] The oxygen concentrator body is provided with a mounting seat, the side wall of the mounting seat is provided with a fixing seat, and the fixing seat is provided with an oxygen outlet pipe.

[0008] The oxygen humidification cup includes a cup body and an adapter. The top of the cup body is provided with an air inlet and an air outlet. The bottom of the adapter is provided with an air inlet pipe. The side of the adapter is provided with a connecting pipe. The adapter is provided with an air outlet pipe. The bottom of the air outlet pipe extends from the bottom of the adapter. The top of the adapter is provided with a socket for connecting the oxygen supply pipe outside the oxygen concentrator. The top of the air outlet pipe is located in the socket. The air inlet pipe is plugged into the air inlet, and the bottom of the air outlet pipe is plugged into the air outlet.

[0009] The end portion of the adapter provided with the connecting pipe is inserted into the fixing seat so that the connecting pipe is communicated with the oxygen outlet pipe, and the oxygen humidification cup is detachably connected to the mounting seat.

[0010] The oxygen concentrator of the present invention, when the oxygen humidification cup is installed on the oxygen concentrator body, the user holds the adapter and pushes the adapter horizontally to insert the end of the adapter provided with the connecting pipe into the fixing seat on the oxygen concentrator body so that the connecting pipe is inserted into the oxygen outlet pipe in the fixing seat to achieve communication, and the end of the oxygen supply pipe connected to the nasal plug oxygen inhalation tube or the oxygen inhalation nasal mask is installed on the plug seat on the adapter. When the oxygen concentrator body is working, the oxygen produced by the oxygen concentrator body enters the cup body through the oxygen outlet pipe, the connecting pipe, the air inlet pipe and the air inlet in the fixing seat. After being moistened by water in the cup body, the oxygen is discharged to the nasal plug oxygen inhalation tube or the oxygen inhalation nasal mask through the air outlet, the air outlet pipe, the plug seat and the oxygen supply pipe outside the oxygen concentrator in sequence for the user to breathe. The water content of the oxygen discharged from the oxygen supply pipe is increased, thereby achieving humidification of the oxygen. The oxygen concentrator of the present invention, after humidification by the cup body The oxygen is directly output to the oxygen supply pipe outside the oxygen concentrator. The humidified oxygen does not need to be output back to the pipe inside the oxygen concentrator body. This can avoid condensation of water vapor carried by the humidified oxygen in the pipe inside the oxygen concentrator body, thereby ensuring the humidity of the oxygen entering the oxygen supply pipe. When the oxygen humidification cup needs to be removed from the oxygen concentrator body, just hold the adapter and pull the adapter outward horizontally to pull the end of the adapter out of the fixing seat on the oxygen concentrator body. The oxygen humidification cup is very convenient to assemble and disassemble, and the connection structure between the oxygen humidification cup and the oxygen concentrator body is simple. In addition, the oxygen supply pipe outside the oxygen concentrator is detachably connected to the adapter, and the adapter is detachably connected to the cup body. The oxygen humidification cup and the oxygen supply pipe outside the oxygen concentrator can be transported and stored as a whole. At the same time, it is also convenient to clean the adapter and the cup body separately to ensure hygiene and safety.

[0011] Furthermore, the fixing base is concave in shape, and its longitudinal cross-section is oblong. The outer shape of the end of the adapter, on which the connecting tube is provided, matches the concave shape of the fixing base. Therefore, the end of the adapter, on which the connecting tube is provided, can be quickly inserted into the fixing base, enabling quick installation and removal of the oxygen humidifier cup.

[0012] Furthermore, a plurality of evenly distributed ribs are provided on the inner wall of the fixing seat.

[0013] When one end of the adapter provided with the connecting pipe is inserted into the fixing seat, the rib is located between the outer wall of the end of the adapter and the inner wall of the fixing seat.

[0014] Therefore, when the end of the adapter provided with the connecting tube is inserted into the fixing seat, the ribs are arranged around the periphery of the adapter to increase the friction between the end of the adapter provided with the connecting tube and the inner wall of the fixing seat, ensuring that the adapter is firmly inserted into the fixing seat and the adapter will not easily fall out of the fixing seat.

[0015] Furthermore, the other end of the adapter is arc-shaped.

[0016] Therefore, in this case, the adapter is held by hand at one end in an arc shape and pushed laterally, and the end of the adapter is inserted into the fixing seat on the oxygen concentrator body so that the connecting pipe on the adapter is inserted into the oxygen outlet pipe in the fixing seat to achieve communication. Since the end of the adapter is designed in an arc shape, when the adapter is held by hand at one end in an arc shape and pushed laterally, the end of the adapter designed in an arc shape will not cause sharp corners to press on the palm, thereby ensuring comfortable operation.

[0017] Furthermore, it also includes a cap body and a pressure relief block. The top of the adapter is provided with a convex ring and a pressure relief hole. The pressure relief hole is located at the bottom of the space enclosed by the convex ring. The side wall of the convex ring is provided with a notch. The bottom of the cap body is provided with a convex column. The pressure relief block is provided with a concave cavity. The bottom of the convex column is inserted into the cavity. The cap body cover is provided on the top of the convex ring. The bottom of the adapter is provided with an accommodating cavity, and the cap body is accommodated in the accommodating cavity.

[0018] When the air pressure in the cup is less than or equal to the set value, the pressure relief block blocks the pressure relief hole.

[0019] When the air pressure in the cup body is greater than the set value, the pressure relief block is separated from the pressure relief hole and the gas in the cup body can be discharged through the notch on the side wall of the convex ring.

[0020] Therefore, since the bottom of the boss is inserted in the cavity, the pressure relief block has an up and down floating space at the bottom of the boss. When the pressure of the oxygen in the cup body is greater than the set value, the oxygen in the cup body will push the pressure relief block upward through the pressure relief hole to separate the pressure relief block from the pressure relief hole. At this time, part of the oxygen will leak out through the notch on the side wall of the convex ring. When the air pressure in the cup body is less than or equal to the set value, the pressure relief block will block the pressure relief hole downward under the action of its gravity, thereby ensuring that the pressure of the oxygen in the cup body remains within a reasonable range. The presence of the boss on the cap body can ensure that the pressure relief block is always located directly above the pressure relief hole to prevent the pressure relief block from being displaced during the up and down floating process. Moreover, the presence of the accommodating cavity can ensure that the cap body is always covered on the top of the convex ring, ensuring that the bottom of the boss on the cap body can always be inserted into the cavity on the pressure relief block, ensuring that the pressure relief block is always located directly above the pressure relief hole.

[0021] Furthermore, the bottom of the cup body is open and is provided with a heat-conducting cover. The bottom of the cup body is provided with a convex edge extending outward, and the heat-conducting cover is provided with an inner groove facing the center of the heat-conducting cover. The convex edge of the cup body is inserted into the inner groove. Therefore, a heating component can be provided on the oxygen concentrator body. After the oxygen humidification cup is installed on the oxygen concentrator body, the heating component can heat the heat-conducting cover at the bottom of the cup body. The heat-generating heat-conducting cover can heat the water in the cup body. The controller of the oxygen concentrator body controls the heating component to maintain the temperature of the water in the cup body within a certain range, ensuring that the humidified oxygen maintains a certain temperature, allowing the user to breathe comfortable oxygen.

[0022] Furthermore, the mounting base is provided with two transverse slots, and the edge of the heat-conducting cover protrudes from the peripheral wall of the cup body.

[0023] When the end portion of the adapter provided with the connecting pipe is inserted into the fixing seat, the edge of the heat-conducting cover is laterally clamped in the two transverse slots.

[0024] Therefore, the cup body can be horizontally inserted between the two horizontal slots on the mounting base through the heat conductive cover at the bottom, and the cup body can be removed from the mounting base by pulling it out horizontally, so the oxygen humidification cup is very convenient to install and disassemble.

[0025] Furthermore, a through hole is provided on the mounting seat, two transverse slots are located on the periphery of the through hole, a heating plate is provided in the oxygen concentrator body, a protrusion is provided on the heating plate, the heating plate is arranged at the bottom of the mounting seat and the protrusion on the heating plate extends out of the through hole,

[0026] When the edge of the heat-conducting cover is transversely engaged in the two transverse slots, the heat-conducting cover contacts the raised portion on the heating plate.

[0027] Therefore, when the edge of the heat-conducting cover is laterally clamped in the two transverse slots, the heat-conducting cover contacts the raised portion on the heating plate. When the heating plate is working, the heating plate can heat the heat-conducting cover at the bottom of the cup body, and the heated heat-conducting cover can complete the heating of the water in the cup body.

[0028] Furthermore, the device includes a cover body, with a bendable belt body provided on the side of the cover body. The end of the belt body is located on the socket, and the cover body can cover the top of the socket. Therefore, when the oxygen supply tube outside the oxygen concentrator is removed from the adapter, the belt body can be bent to cover the top of the socket, preventing foreign matter and dust from entering the socket, ensuring hygienic safety.

[0029] Furthermore, two sloped slots are provided on the inner wall of the socket, and the slots are provided with card slots for adapting to the ends of the oxygen supply tubes outside the oxygen concentrator. The external oxygen supply tube of the oxygen concentrator can be installed with an end head, and plug-ins arranged obliquely are respectively provided on both sides of the end head (the shape of the plug-in is adapted to the shape of the slot), and a buckle is formed on the plug-in (the shape of the buckle is adapted to the shape of the slot), and the external oxygen supply tube of the oxygen concentrator can be snapped into the slot on the socket through the buckles on the two plug-ins on the end head, ensuring that the end head of the external oxygen supply tube of the oxygen concentrator can be firmly plugged into the socket and will not be easily dislodged. When the external oxygen supply tube of the oxygen concentrator needs to be removed from the socket on the adapter, the two plug-ins on the end head of the oxygen supply tube are held and pressed inwardly, the buckles on the plug-in are dislodged from the slots, and then the oxygen supply tube is pulled out outward. The installation and removal of the external oxygen supply tube of the oxygen concentrator are very convenient, and the obliquely arranged plug-ins on the end head of the oxygen supply tube not only facilitates the insertion of the end head into the socket, but also ensures that the buckles on the plug-in are snapped outward into the slots on the slot and will not be easily dislodged.

[0039] See Figures 1 to 7 An oxygen concentrator includes an oxygen concentrator body 1, an oxygen humidification cup 2, a cap body 3, a pressure relief block 4 and a cover body 5.

[0040] See Figure 1 and Figure 2 The oxygen concentrator body 1 is provided with a mounting seat 11, which is located at a corner of the top of the oxygen concentrator body 1. A fixing seat 12 is provided on the side wall of the mounting seat 11. Figure 2 and Figure 3 The fixing seat 12 is in a concave shape, that is, the fixing seat 12 is hollow and has open sides. An oxygen outlet pipe 13 is installed in the fixing seat 12, and the oxygen prepared by the oxygen generator body 1 can be output through the oxygen outlet pipe 13.

[0041] See Figure 1 、 Figures 4 to 7 The oxygen humidification cup 2 includes a cup body 21 and an adapter 22 .

[0042] See Figures 4 to 7 The top of the cup body 21 is provided with an air inlet 211 and an air outlet 212. Specifically, in this embodiment, refer to Figure 6 and Figure 7 The top of the cup body 21 is open, and a cup cover 217 is installed on the top of the cup body 21. The cup cover 217 is threadedly connected to the cup body 21. The air inlet 211 and the air outlet 212 are set on the cup cover 217. The air inlet 211, the air outlet 212, and the cup cover 217 can be formed in one piece. Water can be added to the cup body 21 by unscrewing the cup cover 217 from the cup body 21. The detachable connection between the cup cover 217 and the cup body 21 also facilitates cleaning the inside of the cup body 21.

[0043] The adapter 22 is mounted on the cup body 21. Specifically, the adapter 22 is mounted on the cup cover 217 of the cup body 21. Figure 6 and Figure 7 The bottom of the adapter 22 is equipped with an air inlet pipe 221, and the side of the adapter 22 is equipped with a connecting pipe 222. The air inlet pipe 221 and the connecting pipe 222 are both inserted into the adapter 22. The air inlet pipe 221 and the connecting pipe 222 are connected and arranged at 90 degrees. An air outlet pipe 223 is installed on the adapter 22, and the air outlet pipe 223 is longitudinally inserted into the adapter 22. The bottom of the air outlet pipe 223 extends from the bottom of the adapter 22, and the top of the air outlet pipe 223 extends from the top of the adapter 22. A socket 224 is installed on the top of the adapter 22, and the socket 224 can be snapped onto the adapter. The connector 22 is inserted into a groove at the top and is locked by screws. The top of the outlet pipe 223 is located in the socket 224. The inlet pipe 221 is plugged into the air inlet 211. The bottom of the outlet pipe 223 is plugged into the air outlet 212. Sealing rings (not shown) are installed on the inlet pipe 221 and the outlet pipe 223 to ensure the sealing of the connection. The adapter 22 is detachably connected to the cup body 21, and the adapter 22 can be directly removed from the cup cover 217 of the cup body 21. In this way, it is convenient to clean the adapter 22, the cup body 21 and the cup cover 217 separately to ensure hygiene and safety.

[0044] See Figure 1 The end of the adapter 22 provided with the connecting pipe 222 is inserted into the fixing seat 12, and the connecting pipe 222 on the adapter 22 is inserted into the oxygen outlet pipe 13 in the fixing seat 12 to achieve communication. A sealing ring (not shown) can be installed on the connecting pipe 222 to ensure the sealing of the connection between the connecting pipe 222 and the oxygen outlet pipe 13. When the oxygen concentrator is working, the oxygen prepared by the oxygen concentrator body 1 enters the cup body 21 through the oxygen outlet pipe 13, the connecting pipe 222, the air inlet pipe 221, and the air inlet port 211. After being moistened by the water in the cup body 21, the oxygen is discharged into the socket 224 through the air outlet 212 and the air outlet pipe 223 in sequence.

[0045] See Figure 2 and Figure 3 The longitudinal section of the fixing seat 12 is in the shape of an oblong circle, see Figure 5 The outer shape of the end of the adapter 22 provided with the connecting tube 222 is adapted to the shape of the concave cavity of the fixing seat 12, that is, the longitudinal section of the end of the adapter 22 provided with the connecting tube 222 is also in an oblong shape. In this way, the end of the adapter 22 provided with the connecting tube 222 can be quickly inserted into the fixing seat 12 to achieve rapid assembly and disassembly of the oxygen humidifier cup 2.

[0046] See Figure 2 and Figure 3A plurality of evenly distributed ribs 121 are formed on the inner wall of the fixing seat 12, and the plurality of ribs 121 are evenly distributed on the inner wall of the fixing seat 12. When one end of the adapter 22 provided with the connecting tube 222 is inserted into the fixing seat 12, the ribs 121 are located between the outer wall of the end of the adapter 22 and the inner wall of the fixing seat 12. In this way, when the end of the adapter 22 provided with the connecting tube 222 is inserted into the fixing seat 12, the ribs 121 are arranged around the periphery of the adapter 22 to increase the friction between the one end of the adapter 22 provided with the connecting tube 222 and the inner wall of the fixing seat 12, thereby ensuring that the adapter 22 is firmly plugged into the fixing seat 12 and the adapter 22 will not easily fall out of the fixing seat 12.

[0047] See Figure 5 and Figure 6 One end of the adapter 2 provided with the connecting tube 22 is flat, and the other end of the adapter 2 is arc-shaped. In this way, when the arc-shaped end of the adapter 22 is held by hand and the adapter 22 is pushed laterally, the end of the adapter 22 is inserted into the fixing seat 12 on the oxygen concentrator body 1 so that the connecting tube 222 on the adapter 22 is inserted into the oxygen outlet pipe 13 in the fixing seat 12 to achieve communication. Since the end of the adapter 22 is designed in an arc shape, when the arc-shaped end of the adapter 22 is held by hand and the adapter 22 is pushed laterally, the arc-shaped end of the adapter 22 will not cause sharp corners to press on the palm, thereby ensuring comfortable operation.

[0048] The top of the cup body 21 is provided with a convex ring 213 and a pressure relief hole 214. Figure 6 and Figure 7The convex ring 213 and the pressure relief hole 214 are arranged on the cup cover 217 of the cup body 21. The convex ring 213, the pressure relief hole 214 and the cup cover 217 can be integrally formed. The top of the cup cover 217 is integrally formed with a convex ring 213 that protrudes upward. The pressure relief hole 214 is formed on the cup cover 217. The pressure relief hole 214 is located at the bottom of the space enclosed by the convex ring 213. The side wall of the convex ring 213 is formed with a notch 2131 near the top of the convex ring 213. The top of the notch 2131 is open. The cap body 3 A convex column 31 is formed at the bottom, and a concave cavity 41 is formed on the pressure relief block 4. The cross section of the cavity 41 can be circular, and the inner diameter of the cavity 41 is larger than the diameter of the convex column 31. The bottom of the convex column 31 is inserted into the cavity 41, and the cap body 3 is covered on the top of the convex ring 213. In order to ensure that the cap body 3 can be firmly covered on the top of the convex ring 213, the top of the convex ring 213 is formed with a circle of bosses near the inner wall, and a circle of steps is formed on the inner wall of the cap body 3 to adapt to the bosses on the convex ring 213. The cap body 3 is covered on When the top of the convex ring 213 is on the top, the boss on the convex ring 213 is inserted into the cap body 3 and presses upward on the step on the inner wall of the cap body 3; since the bottom of the convex column 31 is inserted into the cavity 41, the pressure relief block 4 has an upper and lower floating space at the bottom of the convex column 31. When the air pressure in the cup body 21 is less than or equal to the set value, the pressure relief block 4 blocks the pressure relief hole 214 downward under the action of its own gravity. At this time, the bottom of the convex column 31 does not contact the inner bottom of the cavity 41, providing floating space for the pressure relief block 4 to float upward When the air pressure in the cup body 21 is greater than the set value, the oxygen in the cup body 21 will push the pressure relief block 4 upward through the pressure relief hole 214 to separate the pressure relief block 4 from the pressure relief hole 214. At this time, part of the oxygen will leak out through the notch 2131 on the side wall of the convex ring 213, thereby ensuring that the pressure of the oxygen in the cup body 21 is maintained within a reasonable range. The presence of the convex column 31 on the cap body 3 can ensure that the pressure relief block 4 is always located directly above the pressure relief hole 214 to prevent the pressure relief block 4 from being displaced during the up and down floating process.

[0049] See Figure 7 A receiving cavity 225 is formed at the bottom of the adapter 22, and the cap body 3 is received in the receiving cavity 225. In this way, it can be ensured that the cap body 3 is always covered on the top of the convex ring 213, and that the bottom of the convex column 31 on the cap body 3 can always be inserted into the cavity 41 on the pressure relief block 4, ensuring that the pressure relief block 4 is always located directly above the pressure relief hole 214.

[0050] See Figure 1 、 Figures 4 to 7The side of the cover body 5 is integrally formed with a bendable belt body 51, and a fixing hole 2241 can be formed on the side wall of the socket 224 near the bottom. The free end of the belt body 51 is T-shaped, and the free end of the belt body 51 is inserted into the fixing hole 2241 on the socket 224 and will not fall out. The cover body 5 can cover the top of the socket 224. In this way, when the oxygen supply pipe outside the oxygen concentrator is removed from the socket 224, the cover body 5 can be covered on the top of the socket 224 to prevent foreign matter or dust from entering the socket 224, ensuring hygiene and safety. When the oxygen supply pipe needs to be installed, the cover body 5 can be removed from the socket 224. Since the end of the belt body 51 of the cover body 5 is fixed on the socket 224, the cover body 5 will not be lost.

[0051] See Figures 4 to 7 The bottom of the cup body 21 is open, and a heat-conducting cover 215 is installed at the bottom of the cup body 21. Specifically, a convex edge 216 extending outward is formed at the bottom of the cup body 21, and an inner groove 2151 facing the center of the heat-conducting cover 215 is formed on the heat-conducting cover 215. The convex edge 216 at the bottom of the cup body 21 is inserted into the inner groove 2151, and the edge of the heat-conducting cover 215 protrudes from the peripheral wall of the cup body 21. In order to ensure sealing, a sealing ring can be installed in the inner groove 2151. The sealing ring is located between the convex edge 216 and the inner bottom of the inner groove 2151.

[0052] See Figure 1 and Figure 2 The mounting base 11 is formed with two transverse slots 14 and a through hole 15. The two transverse slots 14 are located outside the through hole 15. The inner wall of the transverse slot 14 is arc-shaped. The inner wall of the two transverse slots 14 can just snap on the edge of the heat conductive cover 215 ( Figure 1The state shown), a heating plate 16 is installed in the oxygen concentrator body 1, and a protrusion (not shown) is formed on the heating plate 16. The heating plate 16 is installed at the bottom of the mounting seat 11 and the protrusion on the heating plate 16 extends from the through hole 15. When the end of the adapter 22 provided with the connecting pipe 222 is inserted into the fixing seat 12, the edge of the heat-conducting cover 215 is laterally clamped in the two transverse slots 14. At this time, the heat-conducting cover 215 contacts the protrusion on the heating plate 16; the cup body 21 can be laterally inserted between the two transverse slots 14 on the mounting seat 11 through the heat-conducting cover 215 at the bottom. The oxygen humidifier cup 2 is mounted on the mounting seat 11 of the oxygen concentrator body 1, and the cup body 21 can be removed from the mounting seat 11 by pulling it outward laterally. The cup body 21 is very convenient to assemble and disassemble. When the heating disc 16 is working, the heating disc 16 can heat the heat-conducting cover 215 at the bottom of the cup body 21, and the heated heat-conducting cover 215 can heat the water in the cup body 21. The controller of the oxygen concentrator body 1 can maintain the temperature of the water in the cup body 21 within a certain range by controlling the heating disc 16, ensuring that the humidified oxygen maintains a certain temperature, so that the user can breathe comfortable oxygen.

[0053] See Figure 6 Two inclined slots 2241 are formed on the inner wall of the socket 224, and a card slot 2242 is formed on the slot 2241. The oxygen supply pipe outside the oxygen concentrator can be installed with an end head. Both sides of the end head are respectively provided with plug-ins arranged obliquely and adapted to the shape of the slot 2241. The plug-in is formed with a buckle adapted to the shape of the card slot 2242; in this way, the oxygen supply pipe outside the oxygen concentrator can be snapped into the card slot 2242 on the socket 224 through the buckles on the two plug-ins on the end head, ensuring that the end of the oxygen supply pipe outside the oxygen concentrator can be firmly plugged in The socket 224 will not fall out easily. When the oxygen supply tube outside the oxygen concentrator needs to be removed from the socket 224 on the adapter 22, the two plugs on the end of the oxygen supply tube are held by hand and pressed inward. The buckles on the plugs come out of the slots 2242, and then the oxygen supply tube is pulled out. The installation and removal of the oxygen supply tube outside the oxygen concentrator are very convenient. The obliquely arranged plugs on the end of the oxygen supply tube are convenient for the end to be plugged into the socket 224, and can ensure that the buckles on the plugs are not easily removed after being snapped outward into the slots 2242 on the slots 2241.

[0054] See Figures 1 to 7When installing the oxygen humidifier cup 2 of the present invention, hold the curved end of the adapter 22 and push the adapter 22 horizontally, and insert the end of the adapter 22 provided with the connecting pipe 222 into the fixing seat 12 on the oxygen concentrator body 1 so that the connecting pipe 222 on the adapter 22 is inserted into the oxygen outlet pipe 13 in the fixing seat 12 to achieve communication. At the same time, the cup body 21 is horizontally inserted between the two horizontal slots 14 on the mounting seat 11 through the heat-conducting cover 215 at the bottom, and the end of the oxygen supply tube outside the oxygen concentrator connected to the nasal obstruction oxygen inhalation tube or the oxygen inhalation nasal mask is inserted and fixed on the plug seat 224 on the adapter 2. The heating plate 16 on the oxygen concentrator body 1 can heat the heat-conducting cover 215 at the bottom of the cup body 21.When the oxygen concentrator is working, the oxygen produced by the oxygen concentrator enters the cup body 21 through the oxygen outlet pipe 13, the connecting pipe 222, the air inlet pipe 221, and the air inlet 211. After being moistened by the water in the cup body 21, the oxygen is discharged through the air outlet 212, the air outlet pipe 223, the socket 224, and the oxygen supply pipe to the nasal plug oxygen inhalation tube or the oxygen inhalation nasal mask for the user to breathe. The water content of the oxygen discharged from the oxygen supply pipe increases, thereby achieving oxygen humidification. When the oxygen supply pipe is removed from the socket 224, the cover body 5 can be covered on the top of the socket 224 to prevent foreign matter or dust from entering the socket 224, thereby ensuring hygiene and safety. In the new oxygen concentrator, the oxygen humidified by the cup body 21 is directly output to the oxygen supply pipe outside the oxygen concentrator. The humidified oxygen does not need to be output back to the pipeline inside the oxygen concentrator body 1, which can avoid the condensation of water vapor carried by the humidified oxygen in the pipeline inside the oxygen concentrator body 1, thereby ensuring the humidity of the oxygen entering the oxygen supply pipe. At the same time, the heating plate 16 on the oxygen concentrator body 1 can heat the heat-conducting cover 215 at the bottom of the cup body 21, and the heated heat-conducting cover 215 can heat the water in the cup body 21. The controller of the oxygen concentrator body 1 can maintain the temperature of the water in the cup body 21 at a constant temperature by controlling the heating plate 16. Within a certain range, it is ensured that the humidified oxygen maintains a certain temperature, so that the user can breathe comfortable oxygen. When the oxygen humidification cup 2 needs to be removed from the oxygen concentrator body 1, the adapter 22 is held and pulled outward laterally to extract the end of the adapter 22 from the fixing seat 12 on the oxygen concentrator body 1. At the same time, the heat conductive cover 215 at the bottom of the cup body 21 is extracted from the two horizontal slots 14. The oxygen humidification cup 2 is very convenient to assemble and disassemble. The connection structure between the oxygen humidification cup 2 and the oxygen concentrator body 1 is simple. In addition, the oxygen supply pipe outside the oxygen concentrator is detachably connected to the adapter 22, and the adapter 22 and the cup body are detachably connected. The detachable connection 21 allows the oxygen humidifier cup 2 and the oxygen supply tube outside the oxygen concentrator to be transported and stored as a whole. This also facilitates separate cleaning of the adapter 22 and cup body 21, ensuring hygiene and safety. Furthermore, when the air pressure in the cup body 21 is less than or equal to the set value, the pressure relief block 4, under the action of its own gravity, blocks the pressure relief hole 214 downward. When the air pressure in the cup body 21 exceeds the set value, the oxygen in the cup body 21 will pass through the pressure relief hole 214, pushing up the pressure relief block 4. Some of the oxygen will escape through the notch 2131 on the side wall of the convex ring 213, ensuring that the oxygen pressure in the cup body 21 remains within a reasonable range.

[0055] The above description is only some embodiments of the present invention, which is intended to illustrate the technical means of the present invention and is not intended to limit the technical scope of the present invention. Any obvious improvements made by those skilled in the art based on existing common knowledge to the present invention shall fall within the scope of protection of the present invention.
