Description

Technical Field

[0001] The utility model belongs to the technical field of connectors, and in particular relates to a sliding 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

[0051] Reference Figure 1-Figure 5 A sliding atomizing joint device for an oxygen concentrator comprises a joint body and an air flow channel arranged inside the joint body. The joint device is provided with a conduction mechanism for controlling the opening or closing of the air flow channel. The outer wall of the joint body is slidably connected with a driving part for driving the conduction mechanism to slide.

[0052] Those skilled in the art can understand that one end of the connector body is respectively connected to the atomizing tube inside the oxygen generator housing 60, and the other end is connected to the atomizing conduit 50 used to connect the atomizing assembly 90. It should be noted that in the process of connecting the connector body and the atomizing conduit 50, the end of the atomizing conduit 50 abuts against the driving part and pushes the driving part to slide along the outer wall of the connector body. When the atomizing conduit 50 is connected to the connector body, the end of the atomizing conduit 50 just pushes the driving part from the initial position to the specified position. When the driving part reaches the specified position, the conduction mechanism connects the airflow channel so that the oxygen output from the atomizing tube of the oxygen generator enters the atomizing conduit 50 along the airflow channel. When the atomization is completed, the atomizing conduit 50 is pushed to the atomizing conduit 50. The driving part slides in the 0 direction so that the driving part pushes the atomizing conduit 50 out of the joint body to separate the atomizing conduit 50 from the joint body. At the same time, after the driving part slides from the designated position to the initial position, the conducting mechanism controls the airflow channel to be closed; the driving part controls the conducting mechanism so that the conducting mechanism controls the opening and closing of the airflow channel, which simplifies the operation steps of controlling the opening or closing of the airflow channel and improves the control efficiency of controlling the state of the airflow channel; the driving part is slidably connected to the joint body, and the joint body can limit the sliding stroke of the driving part. On the one hand, the driving part can and can only slide between the initial position and the designated position, and on the other hand, it prevents the driving part from being lost after sliding away from the joint body.

[0053] As a specific embodiment of the connector body in this application, refer to Figure 1-Figure 9 The joint body includes an upper valve core 10 and a lower valve core 20 , the upper valve core 10 and the lower valve core 20 are detachably connected, and a guide cavity is provided in the lower valve core 20 .

[0055] The upper valve core 10 and the lower valve core 20 can be specifically connected by a thread. The threaded connection between the upper valve core 10 and the lower valve core 20 is coated with thread sealing anaerobic glue to increase the sealing of the threaded connection between the upper valve core 10 and the lower valve core 20 to prevent oxygen leakage from the threaded connection. After the upper valve core 10 is connected to the lower valve core 20, the first air guide cavity is connected to the flow guide cavity, the lower valve core 20 is connected to the atomizing tube in the oxygen generator housing 60, and the upper valve core 10 is connected to the atomizing conduit 50. When the driving part is in the first position, the air guide holes 12 on both sides of the air blocking plate 13 are connected by the conduction mechanism, and the oxygen output in the atomizing tube enters the flow guide cavity, enters the flow guide cavity along the air guide holes 12 on the first air guide cavity, passes through the conduction mechanism, and then enters the second air guide cavity through the air guide holes 12 on the second air guide cavity, and finally is discharged from the second air guide cavity into the atomizing conduit 50; after the atomization is completed, the driving part is pushed to slide and separate the atomizing conduit 50 from the upper valve core 10. At the same time, the driving part slides from the first position to the second position, so that the conduction mechanism closes the passage between the air guide holes 12 on both sides of the air blocking plate 13, thereby preventing the oxygen in the first air guide cavity from entering the second air guide cavity.

[0056] As a specific implementation of the driving unit, refer to Figure 1-Figure 5 as well as Figure 8 The driving part includes a sliding member 30, and the sliding member 30 is a tubular structure.

When the sliding member 30 is in the first position, the air guide holes 12 on both sides of the air blocking plate 13 are all located in the conducting groove 32, so that the conducting groove 32 is connected to the air guide holes 12 on both sides of the air blocking plate 13, and then the oxygen in the first air guide cavity enters the second air guide cavity through the conducting groove 32.

The first sealing ring 40 and the second sealing ring 41 are used to increase the air tightness on both sides of the conducting groove 32 to prevent leakage from the gaps on both sides of the conducting groove 32 during oxygen delivery. When the sliding member 30 is in the second position, the air guide hole 12 connected to the first air guide cavity is located outside the conducting groove 32, and the air guide hole 12 is located between the second sealing ring 41 and the third sealing ring 42.

The existence of the groove 34 can facilitate the operator to push and pull the sliding member 30 to slide, and the setting of the small flange 35 can facilitate increasing the friction resistance between the groove 34 and the operator's palm. In addition, the large flange 33 and the small flange 35 are designed as an integrated part with the sliding member 30, which is beneficial to increase the overall structural strength of the sliding member 30 and improve the service life of the sliding member 30.
