Description

Technical Field

[0001] The utility model belongs to the technical field of oxygen concentrator connectors, and in particular relates to a push-type atomizing connector device for an oxygen concentrator. Background Art

[0002] Oxygen therapy can significantly improve the oxygen content in the blood. For patients with respiratory diseases, it can alleviate symptoms and improve the quality of life. For ordinary users, it can effectively improve the oxygen supply to the brain, relieve fatigue, boost energy, improve work and study efficiency, and to a certain extent improve the body's metabolic capacity and delay aging. With the development of modern society and the improvement of quality of life, people's demand for oxygen concentrators is increasing, and household oxygen concentrators have become a best-selling medical and health care product. At present, most oxygen concentrators have integrated atomization functions. Atomization therapy is a treatment method that uses atomization equipment to disperse drug solutions or powders into tiny droplets or particles, suspend them in the gas, enter the respiratory tract and lungs, and achieve the purpose of cleaning the airways, humidifying the airways, local treatment and systemic treatment. Due to its rapid effect and low cost, atomization therapy is widely used in the treatment and relief of upper respiratory tract and lung diseases.

[0003] The existing oxygen concentrator atomizer joint is mainly composed of three parts, namely, the atomizer cover, the rubber sealing flat washer and the atomizer body, as shown in the figure above. The rubber sealing flat washer is installed on the atomizer cover, and the atomizer cover has threads, which can be screwed into the atomizer body to achieve a sealing effect. When in use, the atomizer cover is unscrewed and the atomizer hose is plugged into the atomizer body.

[0004] However, the existing oxygen concentrator atomizer connector has the following problems: 1. The atomizer cover is cumbersome to screw in and out. During the operation of the oxygen concentrator, there is a high air pressure in the atomizer connector. There is a risk of the atomizer cover popping out when it is screwed out. When the atomizer cover is screwed in, it is affected by the airflow resistance and difficult to screw in. For the elderly, it is very difficult to operate. 2. After the atomizer cover is separated from the atomizer body, there is a risk of loss due to its small size. After being lost, the atomizer port is in a normally open state, which has a great impact on the oxygen concentration. At the same time, the noise of the normally open atomizer port is very loud, even exceeding the normal working noise of the oxygen concentrator body. Utility Model Content

[0020] Preferably, the sealing flat gasket is made of silicone.

[0021] Due to the adoption of the above technical solution, the beneficial effects achieved by the utility model are as follows:

[0022] 1. When the atomizing connector is installed, the end of the valve housing away from the valve body assembly is connected to the atomizing tube in the oxygen concentrator so that the atomizing tube is connected to the flow guide cavity, and the end of the valve housing close to the valve body assembly is connected to the atomizing conduit of the atomizer. When the atomizing conduit of the atomizer is connected to the valve housing, the valve body assembly is first inserted into the inner cavity of the atomizing conduit along the opening at the end of the atomizing conduit. It should be noted that the inner wall of the atomizing conduit is against the end of the valve body assembly so that the inner wall of the atomizing conduit pushes the valve body assembly to slide from the second position to the first position through the end of the valve body assembly. When the valve housing is not connected to the atomizing conduit of the atomizer, the valve body assembly is in the second position under the action of the reset member. When the valve body assembly is in the second position, the conduction structure cuts off the flow guide cavity and the air guide channel. At this time, the oxygen output by the oxygen concentrator is intercepted by the conduction structure to prevent the oxygen output by the oxygen concentrator from leaking. The valve housing is connected to the atomizing conduit of the atomizer by means of interference fit. During the process of connecting the atomizing conduit of the atomizer to the valve housing, the inner wall of the atomizing conduit simultaneously pushes the valve body assembly to slide from the second position to the first position. During the process, the valve body assembly compresses the reset member. After the connection between the atomizing conduit and the valve housing is completed, the valve body assembly is in the first position, and the flow guide cavity and the air guide channel are connected so that the oxygen in the oxygen generator can be input into the atomizer through the flow guide cavity, the air guide channel and the atomizing conduit. When it is necessary to stop the oxygen supply, the atomizing conduit can be directly pulled out from the valve housing. After the atomizing conduit is separated from the valve housing, the valve body assembly is reset from the first position to the second position under the action of the reset member, and the conduction structure cuts off the flow guide cavity and the air guide channel, so that the oxygen output by the oxygen generator cannot be discharged.

[0023] 2. As a preferred embodiment of the utility model, when installing the atomizing catheter and the valve housing, first insert the pressing cap into the atomizing catheter from the atomizing catheter port, the pressing cap diameter is slightly larger than the inner diameter of the atomizing catheter, so that the edge of the pressing cap is against the outer wall of the atomizing catheter, the atomizing catheter is a rubber tube with a certain elasticity, and during the connection between the atomizing catheter and the valve housing, the inner wall of the atomizing catheter applies a thrust to the pressing cap, so that the valve stem and the conducting structure provided on the valve stem slide from the second position to the first position. When the conducting structure is in the first position, the oxygen output from the atomizing tube in the oxygen concentrator enters the air conducting channel through the air conducting hole, and then enters the flow conducting cavity through the conducting structure and is input into the atomizing catheter.

[0024] 3. As a preferred embodiment of the present utility model, the side wall of the valve stem is provided with a plurality of guide blocks, the guide blocks are slidably connected to the inner wall of the valve housing, and air guide grooves are formed between adjacent guide blocks in the same plane, and the air guide grooves and the air guide holes are connected to connect the air guide channel with the atomization duct.

[0025] The setting of the guide block facilitates the cooperation with the inner wall of the valve housing to limit and guide the sliding process of the valve stem. It should also be noted that the edge of the guide block is provided with a chamfer so that the air guide groove can guide the passing oxygen flow and reduce the noise generated when the oxygen flow passes through the air guide groove. On the other hand, the guide block and the valve stem can adopt an integrated design to increase the structural strength of the valve stem and improve the service life of the valve stem.

[0026] 4. As a preferred embodiment of the present utility model, the conducting structure includes a sealing flat washer, which is connected to the end of the valve stem away from the pressing cap, and the end of the valve stem away from the pressing cap is threadedly connected with a nut for fixing the sealing flat washer, the diameter of the guide cavity is larger than the diameter of the air guide channel, and the diameter of the sealing flat washer is between the diameter of the guide cavity and the diameter of the air guide channel, and when the valve stem is in the first position, the sealing flat washer is located in the guide cavity, and when the valve stem is in the second position, the sealing flat washer is located on the end surface of the air guide channel close to the guide cavity, so as to cut off the connection between the guide cavity and the air guide channel.

[0027] Specifically, the diameter of the sealing flat gasket is larger than the diameter of the guide cavity, and the diameter of the air guide channel is larger than the diameter of the sealing flat gasket. Therefore, when the sealing flat gasket is located at the second position, the sealing flat gasket closes the port of the guide cavity. When the sealing flat gasket is located at the first position, the sealing flat gasket no longer seals the port of the guide cavity, and there is an airflow gap between the outer wall of the sealing flat gasket and the inner wall of the air guide channel, so that oxygen on the side of the sealing flat gasket away from the guide cavity passes through the airflow gap and enters the guide cavity.

[0028] Furthermore, the sealing flat gasket is made of silicone material to increase the sealing effect of the guide cavity when the sealing flat gasket is located in the second position.

[0029] 5. As a preferred embodiment of the utility model, the outer wall of the valve stem is provided with a second boss, and the sealing flat washer is located between the second boss and the nut.

[0031] The valve housing adopts a split design of upper housing and lower housing. The upper housing and lower housing are disassembled or installed through threads, which facilitates the partial installation and disassembly of the upper housing, lower housing and various components of the valve body assembly. Each component can be replaced separately if damaged, reducing maintenance costs.

[0032] Furthermore, thread sealing anaerobic adhesive is applied to the threaded joints between the upper shell and the lower shell to increase the sealing performance of the threaded joints between the upper shell and the lower shell to prevent oxygen leakage.

[0033] 7. As a preferred embodiment of the present utility model, the reset member is a truncated cone compression spring, and the two ends of the truncated cone compression spring are respectively a small round end and a large round end, the small round end abuts against the nut, and the large round end abuts against the inner hole of the lower shell.

[0034] When the sealing flat gasket slides from the second position to the first position, the nut cooperates with the inner wall of the lower shell to compress the truncated cone compression spring. The truncated cone compression spring stores energy after being compressed. When the atomization conduit is separated from the upper shell, the truncated cone compression spring stretches and resets and pushes the nut to reset the sealing flat gasket from the first position to the second position. The performance of the truncated cone compression spring is more stable, and the posture of the truncated cone compression spring is more stable during the pressure application and pressure release processes.

[0035] Furthermore, the contact surface between the nut and the small round end is conical, and the conical end surface is easy to match with the small round end of the truncated cone compression spring, thereby increasing the stability of the connection between the nut and the truncated cone compression spring.

[0060] Reference Figure 1-Figure 4 , a push-type atomization joint device for an oxygen concentrator, comprising a valve housing, a valve body assembly arranged in the valve housing, and a reset member arranged between the valve housing and the valve body assembly, wherein a flow guide cavity is arranged in the valve housing, the valve body assembly cooperates with the valve housing to form an air guide channel, the valve body assembly is slidably connected to the valve housing to have a first position in which the flow guide cavity and the air guide channel are connected, and a second position in which the conduction structure cuts off the connection state between the flow guide cavity and the air guide channel, and the reset member can reset the valve body assembly from the first position to the second position when the external force applied to the valve body assembly is removed.

[0061] It can be understood by those skilled in the art that the atomization connector is connected between the atomization tube 100 inside the oxygen concentrator 80 and the atomization conduit 70 connected to the input end of the atomizer 110. Specifically, when the atomization connector is installed, one end of the valve housing away from the valve body assembly is connected to the atomization tube 100 inside the oxygen concentrator 80 so that the atomization tube 100 is connected to the flow guide cavity, and one end of the valve housing close to the valve body assembly is connected to the atomization conduit 70 of the atomizer 110. When the atomizing conduit 70 of the nebulizer 110 is connected to the valve housing, the valve body assembly is first inserted into the inner cavity of the atomizing conduit 70 along the opening at the end of the atomizing conduit 70. It should be noted that the inner wall of the atomizing conduit 70 abuts against the end of the valve body assembly, so that the inner wall of the atomizing conduit 70 pushes the valve body assembly to slide from the second position to the first position through the end of the valve body assembly. When the valve housing is not connected to the atomizing conduit 70 of the nebulizer 110, the valve body assembly is in the second position under the action of the reset member. When the valve body assembly is in the second position, the conduction structure cuts off the guide cavity and the air guide channel. At this time, the oxygen output by the oxygen generator 80 is intercepted by the conduction structure to prevent the oxygen output by the oxygen generator 80 from leaking. The valve housing is connected to the atomizing conduit 70 of the atomizer 110 by means of interference fit. During the process of connecting the atomizing conduit 70 of the atomizer 110 to the valve housing, the inner wall of the atomizing conduit 70 simultaneously pushes the valve body assembly to slide from the second position to the first position. During the process, the valve body assembly compresses the reset member. After the connection between the atomizing conduit 70 and the valve housing is completed, the valve body assembly is in the first position, and the flow guide cavity and the air guide channel are connected so that the oxygen in the oxygen generator 80 can be input into the atomizer 110 through the flow guide cavity, the air guide channel and the atomizing conduit 70. When it is necessary to stop the oxygen supply, the atomizing conduit 70 can be directly pulled out from the valve housing. After the atomizing conduit 70 is separated from the valve housing, the valve body assembly is reset from the first position to the second position under the action of the reset member, and the conduction structure cuts off the flow guide cavity and the air guide channel, so that the oxygen output by the oxygen generator 80 cannot be discharged.

[0062] As a specific embodiment of the valve body assembly, refer to Figure 2-Figure 4 as well as Fig. 9 The valve body assembly includes a valve stem 30 and a conducting structure arranged on the valve stem 30. The valve stem 30 is provided with an extension portion extending outside the valve housing, and a pressing cap 31 is provided on the extension portion. The conducting structure is arranged at one end of the valve stem 30 away from the extension portion.

[0063] Specifically, one end of the valve housing close to the push cap 31 is connected to the atomization conduit 70, and the push cap 31 and the atomization conduit 70 are in an interference fit relationship. A plurality of air guide holes 34 are provided on the push cap 31. During the connection process between the atomization conduit 70 and the valve housing, an external force is applied to the push cap 31 to make the valve stem 30 slide from the second position to the first position.

[0064] When installing the atomizing conduit 70 with the valve housing, first insert the pressing cap 31 into the atomizing conduit 70 from the port of the atomizing conduit 70. The diameter of the pressing cap 31 is slightly larger than the inner diameter of the atomizing conduit 70, so that the edge of the pressing cap 31 abuts against the outer wall of the atomizing conduit 70. The atomizing conduit 70 is a rubber tube with a certain elasticity. During the connection between the atomizing conduit 70 and the valve housing, the inner wall of the atomizing conduit 70 applies a thrust to the pressing cap 31, so that the valve stem 30 and the conducting structure provided on the valve stem 30 slide from the second position to the first position. When the conducting structure is in the first position, the oxygen output from the atomizing conduit 100 in the oxygen concentrator 80 enters the air guiding channel through the air guiding hole 34, and then enters the guide cavity through the conducting structure and is input into the atomizing conduit 70.

[0065] It should also be noted that the present application does not specifically limit the shape of the pressing cap 31, and it can adopt any one of the following embodiments:

[0066] Embodiment 1: Fig.10 As shown, the pressing cap 31 is circular, and four groups of air guide holes 34 are arranged at intervals along the circumference of the pressing cap 31.

[0067] Embodiment 2: Fig.12 As shown, the pressing cap 31 is cross-shaped, and has four recessed areas on the outside. The outer wall of the cross-shaped pressing cap 31 abuts against the inner wall of the atomizing conduit 70 so that the recessed areas cooperate with the inner wall of the atomizing conduit 70 to form an air guide hole 34 structure.

[0068] As a preferred example of the above embodiment, refer to Fig. 9 The side wall of the valve stem 30 is provided with a plurality of guide blocks 32, and the guide blocks 32 are slidably connected to the inner wall of the valve housing. An air guide groove 35 is formed between the adjacent guide blocks 32 in the same plane, and the air guide groove 35 and the air guide hole 34 connect the air guide channel with the atomization conduit 70.

[0069] The setting of the guide block 32 is convenient for cooperating with the inner wall of the valve housing to limit and guide the sliding process of the valve stem 30. It should also be noted that the edge of the guide block 32 is provided with a chamfer so that the air guide groove 35 can guide the passing oxygen flow and reduce the noise generated when the oxygen flow flows through the air guide groove 35. On the other hand, the guide block 32 and the valve stem 30 can adopt an integrated design to increase the structural strength of the valve stem 30 and improve the service life of the valve stem 30.

[0070] As a specific implementation of the conductive structure, refer to Figure 1-Figure 4 , Figure 6 as well as Fig. 9The conduction structure includes a sealing flat washer 40, which is connected to the end of the valve stem 30 away from the pressing cap 31, and the end of the valve stem 30 away from the pressing cap 31 is threadedly connected with a nut 50 for fixing the sealing flat washer 40. The diameter of the guide cavity is larger than the diameter of the air guide channel, and the diameter of the sealing flat washer 40 is between the diameter of the guide cavity and the diameter of the air guide channel. When the valve stem 30 is in the first position, the sealing flat washer 40 is located in the guide cavity. When the valve stem 30 is in the second position, the sealing flat washer 40 is located on the end surface of the air guide channel close to the guide cavity, so as to cut off the connection between the guide cavity and the air guide channel.

[0071] Specifically, the diameter of the sealing flat gasket 40 is larger than the diameter of the guide cavity, and the diameter of the air guide channel is larger than the diameter of the sealing flat gasket 40. Therefore, when the sealing flat gasket 40 is located at the second position, the sealing flat gasket 40 closes the port of the guide cavity. When the sealing flat gasket 40 is located at the first position, the sealing flat gasket 40 no longer seals the port of the guide cavity, and there is an airflow gap between the outer wall of the sealing flat gasket 40 and the inner wall of the air guide channel, so that oxygen on the side of the sealing flat gasket 40 away from the guide cavity passes through the airflow gap and enters the guide cavity.

[0072] Furthermore, the sealing flat gasket 40 is made of silicone material to increase the sealing effect of the guide cavity when the sealing flat gasket 40 is located at the second position.

[0073] As a preferred example of the valve stem 30, refer to Fig. 9 A second boss 33 is provided on the outer wall of the valve stem 30, and the sealing flat washer 40 is located between the second boss 33 and the nut 50. The second boss 33 is provided to provide a supporting surface for the sealing flat washer 40, and the sealing flat washer 40 is fixed in cooperation with the nut 50. The second boss 33 and the valve stem 30 are designed as an integrated whole to further increase the structural strength of the valve stem 30 and improve the service life of the valve stem 30.

[0074] As a specific embodiment of the valve housing, refer to Figure 1-Figure 4 , Figure 6-Figure 8 The valve housing includes an upper housing 10 and a lower housing 20 , wherein the upper housing 10 is connected to the lower housing 20 by threads, the atomization conduit 70 is connected to the upper housing 10 , and the lower housing 20 is used to connect the atomization tube 100 inside the oxygen concentrator 80 body.

[0075] The valve housing adopts a split design of an upper shell 10 and a lower shell 20. The upper shell 10 and the lower shell 20 are disassembled or installed by threads, which facilitates the partial installation and disassembly of the upper shell 10, the lower shell 20 and the various components of the valve body assembly. Each component can be replaced individually if damaged, reducing maintenance costs.

[0076] Furthermore, thread sealing anaerobic adhesive is applied to the threaded joints between the upper shell 10 and the lower shell 20 to increase the sealing performance of the threaded joints between the upper shell 10 and the lower shell 20 and prevent oxygen leakage.

[0077] As a preferred example of a reset member, refer to Fig.11 The reset member is a truncated cone compression spring 60 , and the two ends of the truncated cone compression spring 60 are respectively a small round end 61 and a large round end 62 . The small round end 61 abuts against the nut 50 , and the large round end 62 abuts against the inner hole of the lower shell 20 .

[0078] When the sealing flat gasket 40 slides from the second position to the first position, the nut 50 cooperates with the inner wall of the lower shell 20 to compress the truncated cone compression spring 60. The truncated cone compression spring 60 stores energy after being compressed. When the atomization duct 70 is separated from the upper shell 10, the truncated cone compression spring 60 stretches and resets and pushes the nut 50 to reset the sealing flat gasket 40 from the first position to the second position. The performance of the truncated cone compression spring 60 is more stable, and the posture of the truncated cone compression spring 60 is more stable during the pressure process and the pressure release process.

[0079] Furthermore, the contact surface between the nut 50 and the small round end 61 is conical, and the conical end surface is easy to match with the small round end 61 of the truncated cone compression spring 60, thereby increasing the stability of the connection between the nut 50 and the truncated cone compression spring 60.

[0080] As a preferred embodiment of the upper housing 10, refer to Figure 6 and Figure 7 The outer wall of the upper shell 10 is provided with a first flange 11, and the first flange 11 is a barb structure, and the first flange 11 is used to prevent the atomization conduit 70 from falling off; on the other hand, the setting of the first flange 11 is convenient for increasing the structural strength of the upper shell 10 and increasing the service life of the upper shell 10.

[0081] As a preferred embodiment of the lower housing 20, refer to Figure 6 and Figure 8 The outer wall of the lower shell 20 is provided with a second flange 22, and the second flange 22 is a barb structure. The second flange 22 is used to prevent the atomization tube 100 inside the oxygen generator 80 body from falling off; on the other hand, the setting of the second flange 22 facilitates increasing the structural strength of the lower shell 20 and increasing the service life of the lower shell 20.

[0082] As a specific implementation of this application, refer to Figure 1-Figure 5The end of the lower shell 20 close to the upper shell 10 is connected to the main shell of the oxygen concentrator 80 by a thread. The outer wall of the lower shell 20 is threadedly connected with a nut 91. The outer wall of the lower shell 20 is provided with a first boss 21. The first boss 21 plays a limiting role and is used to cooperate with the shell of the oxygen concentrator 80 for installation. The outer wall of the lower shell 20 is slidably connected with a corrugated spring washer 90, and the corrugated spring washer 90 is located between the first boss 21 and the nut 91. The setting of the corrugated spring washer 90 facilitates the support and limitation of the nut 91 to prevent the nut 91 from rotating due to vibration, resulting in loosening of the connection between the lower shell 20 and the shell of the oxygen concentrator 80.
