Abstract
Description
Technical Field
[0001] This utility model relates to the field of oxygen generators, and in particular to a humidification cup adapter structure for an oxygen generator. Background Art
[0002] Oxygen concentrators are widely used in homes, hospitals, sanatoriums, schools, hotels, sports venues, bars, oxygen bars, and high-altitude military stations. With people’s increasing awareness of health, the home oxygen concentrator market 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 humidifier cup in an oxygen concentrator is an important component. Its main function is to humidify the oxygen produced by the concentrator so that the oxygen is moistened before inhalation, reducing discomfort to the respiratory tract.
[0004] The humidification cups of existing oxygen concentrators on the market generally do not have bacterial filtration functions, which increases the possibility of bacterial infection for users. Oxygen concentrators with bacterial filters have the filters placed inside the machine, which is inconvenient for users to replace. Furthermore, using the bacterial filter beyond its lifespan can affect the performance parameters of the oxygen concentrator. Utility Model Content
[0005] The purpose of this invention is to overcome the shortcomings of the prior art and provide a humidification cup adapter structure for an oxygen generator.
[0006] According to one aspect of the present invention, a humidification cup adapter structure for an oxygen concentrator is provided, comprising:
[0007] The connector body has a first air inlet for connecting to the oxygen outlet of an oxygen concentrator and a second air inlet for connecting to a humidification cup. The first air inlet and the second air inlet are connected. The connector body also has an air outlet pipe for connecting to the humidification cup.
[0008] The bacterial filter cotton is located on the connector body and between the first air inlet and the second air inlet. The bacterial filter cotton is detachably connected to the connector body.
[0009] This utility model discloses a humidification cup adapter structure for an oxygen concentrator. A first air inlet connects to the oxygen outlet of the oxygen concentrator, a second air inlet connects to the oxygen inlet of the humidification cup, one end of the outlet pipe connects to the oxygen outlet of the humidification cup, and the other end connects to an external oxygen delivery pipe. Oxygen generated inside the oxygen concentrator enters the humidification cup for humidification through the oxygen outlet, the first air inlet, the second air inlet, and the oxygen inlet of the humidification cup. The humidified oxygen is then output through the oxygen outlet of the humidification cup and the outlet pipe to the external oxygen delivery pipe, which delivers the humidified oxygen to a nasal cannula or nasal mask for the user to inhale. Because the bacterial filter cotton is installed between the first and second air inlets and close to the humidification cup, the oxygen generated by the oxygen generator is filtered by the bacterial filter cotton before entering the humidification cup for humidification. The oxygen is filtered by bacteria in the humidification cup, which is closest to the nasal cannula or nasal mask, minimizing the risk of bacterial infection. Moreover, since the bacterial filter cotton is installed on the connector body and is detachably connected to it, the user can easily replace the bacterial filter cotton. In addition, taking advantage of the low cost and plasticity of injection molding of plastic parts, the size of the humidification cup adapter structure of this utility model is controllable in its fit with the humidification cup, allowing for mass production.
[0010] Furthermore, the connector body is provided with a first conical cover and a second conical cover. The first air inlet is connected to the end of the first conical cover with a smaller opening area, and the second air inlet is connected to the end of the second conical cover with a smaller opening area. The end of the first conical cover with a larger opening area is detachably connected to the end of the second conical cover with a larger opening area. The bacterial filter cotton is placed between the first conical cover and the second conical cover.
[0011] Therefore, when oxygen passes through the bacterial filter cotton, it will affect the oxygen flow rate to a certain extent. The first and second conical hoods can effectively increase the amount of oxygen passing through the bacterial filter cotton per unit time, ensuring the oxygen flow rate entering the humidification cup.
[0012] Furthermore, the end face of the larger opening area of the second conical hood is provided with a concave step, and the end face of the larger opening area of the first conical hood is provided with a protrusion that matches the step. The periphery of the bacterial filter cotton is accommodated in the step, and the protrusion presses against the periphery of the bacterial filter cotton.
[0013] Therefore, the bacterial filter cotton is sandwiched between the protrusion on the first conical cover and the step on the second conical cover, ensuring that the bacterial filter cotton can be securely installed between the first and second conical covers.
[0014] Furthermore, the inner wall of the first conical cover is provided with multiple first reinforcing ribs, and the end face of the first reinforcing rib near the end with the larger opening area of the first conical cover is flush with the end face of the boss.
[0015] Therefore, the first reinforcing rib can increase the load-bearing area of the bacterial filter cotton on the first conical cover, ensuring that the bacterial filter cotton is installed firmly.
[0016] Furthermore, the inner wall of the second conical cover is provided with multiple second reinforcing ribs, and the end face of the second reinforcing ribs near the end with the larger opening area of the second conical cover is flush with the step.
[0017] Therefore, the second reinforcing rib can increase the load-bearing area of the bacterial filter cotton on the second conical cover, ensuring that the bacterial filter cotton is installed firmly.
[0018] Furthermore, the outer periphery of the end with the larger opening area of the first conical cover is provided with multiple protrusions, and the outer periphery of the end with the larger opening area of the second conical cover is provided with multiple insertion holes that are adapted to the protrusions, and the protrusions are inserted into the insertion holes.
[0019] Therefore, after inserting the protrusion on the first conical cover into the socket on the second conical cover, the first and second conical covers can be joined together. When it is necessary to replace the bacterial filter cotton, simply pull the protrusion out of the socket and separate the first and second conical covers to remove the bacterial filter cotton. The replacement of the bacterial filter cotton is very convenient.
[0020] Furthermore, the outer periphery of the end with the larger opening area of the first conical cover is provided with a buckle, and the outer periphery of the end with the larger opening area of the second conical cover is provided with a buckle groove that matches the buckle, and the buckle is inserted into the buckle groove.
[0021] Therefore, the protrusion on the first conical cover is first inserted into the insertion hole on the second conical cover with an interference fit, and the first and second conical covers are joined together. At the same time, the buckle on the first conical cover is inserted into the buckle groove on the second conical cover with an interference fit, further locking the first and second conical covers together. When it is necessary to replace the bacterial filter cotton, the buckle is pulled out from the buckle groove and the protrusion is pulled out from the insertion hole, and the first and second conical covers are separated to remove the bacterial filter cotton. The replacement of the bacterial filter cotton is very convenient.
[0022] Furthermore, a sealing ring is provided on the outer periphery of the first air intake.
[0023] Therefore, the sealing ring can ensure the seal between the first air inlet and the oxygen outlet on the oxygen generator.
[0024] Furthermore, the connector body is provided with a terminal socket and a plug for connecting to the oxygen generator controller, and the plug is electrically connected to the terminal socket.
[0025] When the constant temperature oxygen delivery pipe outside the oxygen generator is installed on the outlet pipe, the plug is inserted into the socket on the constant temperature oxygen delivery pipe.
[0026] Therefore, when the constant temperature oxygen delivery tube outside the oxygen generator is plugged into the end of the outlet pipe, the temperature detection device on the constant temperature oxygen delivery tube can feed back the detected oxygen temperature in the constant temperature oxygen delivery tube to the controller of the oxygen generator through the plug and terminal interface. At the same time, the controller of the oxygen generator can control the heating component on the constant temperature oxygen delivery tube to heat the oxygen in the constant temperature oxygen delivery tube through the terminal interface and plug.
[0027] Furthermore, the connector body is equipped with a pipe clamp.
[0028] Therefore, the oxygen delivery tubes on the outside of the oxygen concentrator can be clipped to the tube clamps when not in use, preventing the tubes from being placed randomly, which ensures both hygiene and the overall tidiness of the oxygen concentrator. Attached Figure Description

[0034] See Figures 1 to 3 A humidification cup adapter structure for an oxygen concentrator includes an adapter body 1 and a bacterial filter cotton 2.
[0035] See Figures 1 to 3 The connector body 1 has a second air inlet 12 and a second conical cover 15 formed on it. The two ends of the second conical cover 15 are open and the second conical cover 15 is horn-shaped. The second air inlet 12 is connected to the end of the second conical cover 15 with the smaller opening area. The second air inlet 12 is used to connect to the oxygen inlet on the humidification cup.
[0036] See Figures 1 to 3 The first conical cover 14 has openings at both ends and is flared. The end with the smaller opening area of the first conical cover 14 has a first air inlet 11 formed therein. The first air inlet 11 is connected to the end with the smaller opening area of the first conical cover 14 and is used to connect to the oxygen outlet on the oxygen generator. The end with the larger opening area of the first conical cover 14 is connected to the end with the larger opening area of the second conical cover 15 and is detachably connected. The first air inlet 11 is connected to the second air inlet 12 through the first conical cover 14, the second conical cover 15 and the second air inlet 12.
[0037] See Figures 1 to 3 A sealing ring 111 is installed on the outer periphery of the first air inlet 11. There can be two sealing rings 111. The sealing rings 111 can ensure the sealing between the first air inlet 11 and the oxygen outlet on the oxygen generator.
[0038] The bacterial filter cotton 2 is installed between the first conical hood 14 and the second conical hood 15, specifically: see [link to relevant documentation]. Figure 2 and Figure 3 The second conical cover 15 has a concave step 151 formed on the end face of the larger opening area. Multiple second reinforcing ribs 152 are formed on the inner wall of the second conical cover 15. The end faces of the second reinforcing ribs 152 near the larger opening area of the second conical cover 15 are flush with the step 151. In this embodiment, there are four second reinforcing ribs 152, evenly distributed on the inner wall of the second conical cover 15. The first conical cover 14 has a ring of ribs adapted to the step 151 formed on the end face of the larger opening area. A boss 141 is accommodated in a step 151. Multiple first reinforcing ribs 142 are formed on the inner wall of the first conical cover 14. The end face of the first reinforcing rib 142 near the end with the larger opening area of the first conical cover 14 is flush with the end face of the boss 141. In this embodiment, there are four first reinforcing ribs 142, evenly distributed on the inner wall of the first conical cover 14. The periphery of the bacterial filter cotton 2 is accommodated in the step 151. When the first conical cover 14 and the second conical cover 15 are assembled together... Figure 1 (As shown in the diagram), the boss 141 on the first conical cover 14 presses against the periphery of the bacterial filter cotton 2. The first reinforcing rib 142 can increase the bearing area of the bacterial filter cotton 2 on the first conical cover 14, ensuring that the bacterial filter cotton 2 is firmly installed. The end face of the first reinforcing rib 142 near the end with the larger opening area of the first conical cover 14, together with the boss 141, supports and presses against the bacterial filter cotton 2. The second reinforcing rib 152 can increase the bearing area of the bacterial filter cotton 2 on the second conical cover 15, ensuring that the bacterial filter cotton 2 is firmly installed. The end face of the second reinforcing rib 152 near the end with the larger opening area of the second conical cover 15, together with the boss 141, supports and presses against the bacterial filter cotton 2. The step 151 together supports and presses against the bacterial filter cotton 2. The end face of the first reinforcing rib 142 and the boss 141, and the end face of the second reinforcing rib 152 and the step 151 sandwich the bacterial filter cotton 2 in the middle, ensuring that the bacterial filter cotton 2 can be stably installed between the first conical cover 14 and the second conical cover 15. Moreover, the bacterial filter cotton 2 is located between the first air inlet 11 and the second air inlet 12. When oxygen passes through the bacterial filter cotton 2, it will affect the oxygen flow rate to a certain extent. The first conical cover 14 and the second conical cover 15 can effectively increase the amount of oxygen passing through the bacterial filter cotton 2 per unit time, ensuring the oxygen flow rate entering the humidification cup.
[0039] In other embodiments, the number of the first reinforcing rib 142 and the second reinforcing rib 152 can be adjusted as required to ensure that the end face of each first reinforcing rib 142 near the end with the larger opening area of the first conical cover 14 corresponds to the end face of a second reinforcing rib 152 near the end with the larger opening area of the second conical cover 15, so that the two sides of the bacterial filter cotton 2 are clamped in a balanced manner.
[0040] The end of the first conical cover 14 with the larger opening area is detachably connected to the end of the second conical cover 15 with the larger opening area; specifically: see Figure 2 and Figure 3 In this embodiment, the outer periphery of the end with the larger opening area of the first conical cover 14 has multiple protrusions 143 formed thereon, and the outer periphery of the end with the larger opening area of the second conical cover 15 has multiple insertion holes 153 formed thereon that fit the protrusions 143. The protrusions 143 can be interference-fitted into the insertion holes 153. After the protrusions 143 on the first conical cover 14 are interference-fitted into the insertion holes 153 on the second conical cover 15, the first conical cover 14 and the second conical cover 15 can be combined together. When the bacterial filter needs to be replaced... When replacing the bacterial filter cotton 2, pull the protrusion 143 out of the insertion hole 153, separate the first conical cover 14 and the second conical cover 15, and the bacterial filter cotton 2 can be removed. The replacement of the bacterial filter cotton 2 is very convenient. In this embodiment, there are two protrusions 143, which are located on opposite sides of the outer periphery of the end with the larger opening area of the first conical cover 14. There are also two insertion holes 153, and the positions of the insertion holes 153 correspond to the positions of the protrusions 143. In addition, in order to further ensure the first conical cover 14, the bacterial filter cotton 2 can be removed by pulling out the protrusion 143 from the insertion hole 153. The stability and sealing of the first conical cover 14 and the second conical cover 15 after they are combined are ensured. A buckle 144 is formed on the outer periphery of the end with the larger opening area of the first conical cover 14, and a groove 154 is formed on the outer periphery of the end with the larger opening area of the second conical cover 15 to fit the buckle 144. The buckle 144 can be interference-fitted into the groove 154. In this way, the protrusion 143 on the first conical cover 14 is first interference-fitted into the insertion hole 153 on the second conical cover 15. The first conical cover 14 and the second conical cover 15 then... When the first conical cover 14 and the second conical cover 15 are closed together, the buckle 144 on the first conical cover 14 is inserted into the buckle groove 154 on the second conical cover 15, thereby locking the first conical cover 14 and the second conical cover 15 together. When the bacterial filter cotton 2 needs to be replaced, the buckle 144 is pulled out from the buckle groove 154 and the protrusion 143 is pulled out from the insertion hole 153, and the first conical cover 14 and the second conical cover 15 are separated to remove the bacterial filter cotton 2. The replacement of the bacterial filter cotton 2 is very convenient.
[0041] See Figures 1 to 3 The connector body 1 has an air outlet pipe 13 formed on it, and the lower end of the air outlet pipe 13 is used to connect to the oxygen outlet on the humidification cup.
[0042] See Figures 1 to 3The connector body 1 has a terminal plug interface 16 and a plug 18 formed on it. The terminal plug interface 16 is equipped with a connection terminal. The plug 18 is connected to the terminal plug interface 16 through a wire harness. The terminal plug interface 16 is used to connect to the controller on the oxygen concentrator. When the constant temperature oxygen delivery tube outside the oxygen concentrator is plugged into the upper end of the outlet pipe 13, the plug 18 is plugged into the socket on the constant temperature oxygen delivery tube. The constant temperature oxygen delivery tube is electrically connected to the plug 18. The temperature detection device on the constant temperature oxygen delivery tube can feed back the detected oxygen temperature in the constant temperature oxygen delivery tube to the controller of the oxygen concentrator through the plug 18 and the terminal plug interface 16. At the same time, the controller of the oxygen concentrator can control the heating element on the constant temperature oxygen delivery tube to heat the oxygen in the constant temperature oxygen delivery tube through the terminal plug interface 16 and the plug 18, so that the user can use the oxygen concentrator more comfortably, especially in the cold winter.
[0043] See Figure 1 The connector body 1 has a pipe clamp 17 formed on it. When the oxygen delivery pipe outside the oxygen generator is not in use, it can be clamped on the pipe clamp 17 to prevent the oxygen delivery pipe from being placed randomly. This can ensure both hygiene and the overall cleanliness of the oxygen generator.
[0044] See Figures 1 to 3The humidification cup adapter structure of this utility model for an oxygen concentrator has a first air inlet 11 connected to the oxygen outlet of the oxygen concentrator, a second air inlet 12 connected to the oxygen inlet of the humidification cup, a lower end of an outlet pipe 13 connected to the oxygen outlet of the humidification cup, and an upper end of the outlet pipe 13 connected to an external oxygen delivery pipe of the oxygen concentrator. Oxygen generated inside the oxygen concentrator enters the humidification cup for humidification through the oxygen outlet, the first air inlet 11, the second air inlet 12, and the oxygen inlet of the humidification cup. The humidified oxygen is then output through the oxygen outlet of the humidification cup and the outlet pipe 13. The oxygen is delivered to the external oxygen supply tube of the oxygen concentrator. The external oxygen supply tube delivers humidified oxygen to the nasal cannula or nasal mask for the user to breathe. Because the bacterial filter cotton 2 is installed between the first air inlet 11 and the second air inlet 12, and close to the humidification cup, the oxygen generated by the oxygen concentrator is filtered by the bacterial filter cotton 2 before entering the humidification cup for humidification. Bacterial filtration of the oxygen is performed on the humidification cup, which is closest to the nasal cannula or nasal mask, minimizing the risk of bacterial infection. Furthermore, because the bacterial filter cotton 2 is installed on the first conical hood 14... The first conical cover 14 and the second conical cover 15 are detachably connected. When the bacterial filter cotton 2 needs to be replaced, the buckle 144 on the first conical cover 14 is pulled out of the buckle groove 154 on the second conical cover 15, and the protrusion 143 on the first conical cover 14 is pulled out of the insertion hole 153 on the second conical cover 15. The first conical cover 14 and the second conical cover 15 can then be separated to remove the bacterial filter cotton 2. The replacement of the bacterial filter cotton 2 is very convenient. After replacing the bacterial filter cotton 2, first remove the first conical cover 14... The protruding post 143 is interference-fitted into the insertion hole 153 on the second conical cover 15. The first conical cover 14 and the second conical cover 15 are joined together, and the buckle 144 on the first conical cover 14 is interference-fitted into the buckle groove 154 on the second conical cover 15. At this time, the bacterial filter cotton 2 is replaced, and the user can replace the bacterial filter cotton 2 very conveniently. In addition, taking advantage of the low cost and plasticity of plastic injection molding, the size of the humidification cup adapter structure of this utility model and its compatibility with the humidification cup are controllable, and it can be mass-produced.
[0045] The above descriptions are merely some embodiments of this utility model, intended to illustrate the technical means of this utility model, and are not intended to limit the technical scope of this utility model. Any obvious improvements made to this utility model by those skilled in the art in conjunction with existing common knowledge fall within the protection scope of this utility model.
