Description

Technical Field

[0001] This utility model relates to the field of atomizer technology, and more specifically, to an atomizer connecting tube. Background Technology

[0002] Traditional nebulizer connecting tubes typically use threaded tightening or snap-fit ​​fixing to connect components. These structures are prone to wear and tear during frequent disassembly and assembly, leading to decreased sealing and even air leakage. Especially during use, mechanical vibration or external pulling forces can loosen the connection, affecting the stability and safety of nebulizer treatment. Furthermore, traditional snap-fit ​​structures require precise alignment and are laborious to operate, lacking convenience for medical staff or patients. While existing technologies include elastic sealing rings, relying solely on compression deformation for sealing cannot simultaneously meet the dual requirements of quick disassembly and assembly with long-term stable connection, resulting in increased maintenance costs and a poor user experience.

[0003] In recent years, some improvement solutions have attempted to enhance connection stability by adding spring locks or sliding blocks. However, such structures are often complex and require multiple steps or even tools for disassembly and assembly, which cannot meet the needs of efficient cleaning or replacement in medical settings. In addition, existing elastic locking mechanisms are prone to fatigue failure after being compressed, and their positioning accuracy decreases after long-term use, posing a risk of accidental detachment. Therefore, in response to the above technical problems, a nebulizer connecting tube is proposed here. Utility Model Content

[0004] The purpose of this utility model is to provide an atomizer connecting tube that, through the elastic self-locking of the wedge block and the positioning hole, the bidirectional sealing and elastic assistance of the elastic washer, and the linkage control of the rotating rod and the connecting rope, significantly improves the efficiency of disassembly and assembly while ensuring the stability of the connection. It is especially suitable for medical atomization scenarios that require frequent replacement of connecting tubes or maintenance and cleaning.

[0005] This utility model is achieved through the following technical solution:

[0006] A nebulizer connecting tube includes an nebulizer body and a connecting tube body. The nebulizer body has an external air vent. A tube is fixedly connected to the external side of the nebulizer body. An elastic washer is fixedly connected between the air vent and the tube. A fixing cylinder is fixedly connected to the external side of the nebulizer body and is sleeved outside the tube. A sleeve is fixedly connected to the external side of the connecting tube body and is inserted between the fixing cylinder and the tube. A positioning hole is provided on the external side of the sleeve. Mounting seats are fixedly connected to the upper and lower sides of the fixing cylinder. A positioning mechanism is installed inside the mounting seats. A quick-release mechanism is installed on the external side of the nebulizer body.

[0007] Preferably, the outer surface of the connecting tube body is threaded, and the insert completely covers the vent.

[0008] Preferably, the main body of the connecting pipe abuts against the outside of the elastic washer, and the elastic washer is in a compressed state.

[0009] Preferably, the connecting tube body, vent, insert, elastic washer, sleeve, and fixing cylinder are all coaxial annular structures.

[0010] Preferably, the positioning mechanism includes a wedge block and a compression spring. The wedge block is slidably connected to the outside of the fixed cylinder, and the end of the wedge block is located between the fixed cylinder and the insertion tube. The wedge block matches the positioning hole. The compression spring is fixedly connected to the inside of the mounting base, and the other end of the compression spring is fixedly connected to the outside of the wedge block.

[0011] Preferably, the wedge-shaped block has a bevel on one end side, and the bevel matches the insert.

[0012] Preferably, the quick-release mechanism includes a rotating rod and a connecting rope. The rotating rod is rotatably connected to the outside of the atomizer body and is installed on one side of the insertion tube. The distance between the rotating rod and the two sets of mounting seats is equal. There are two sets of connecting ropes, which are fixedly connected to the outside of the rotating rod. The end of the connecting rope passes through the outside of the mounting seat and is fixedly connected to one side of the wedge block. The compression spring is sleeved on the outside of the connecting rope.

[0013] Preferably, a screw block is fixedly connected to the outside of the rotating rod.

[0014] The technical solution of this utility model has at least the following beneficial effects:

[0015] This utility model proposes an atomizer connecting tube that, through the elastic self-locking of the wedge block and the positioning hole, automatically and accurately positions and fixes the connecting tube body upon insertion, significantly improving airtightness and avoiding the risk of leakage. Furthermore, the compression deformation of the elastic gasket not only seals the gap but also strengthens the lateral contact between the wedge block and the positioning hole through reverse elastic force, effectively resisting loosening or detachment caused by vibration or external impact. During disassembly, simply rotating the screw releases the locks on both sides simultaneously, and the accumulated elastic force of the elastic gasket pushes the connecting tube out quickly, enabling one-handed operation and tool-free rapid separation. The structure is simple and reliable, reducing component wear caused by frequent disassembly and assembly, extending service life through a dual locking mechanism, and simultaneously meeting the requirements of ease of operation, connection stability, and cleaning and maintenance efficiency in medical settings, significantly improving safety and user experience.

[0021] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0022] Please see Figures 1-4 The present invention discloses an atomizer connecting tube, comprising an atomizer body 1 and a connecting tube body 2. The atomizer body 1 has an air vent 3 on its exterior. An insert 4 is fixedly connected to the exterior of the atomizer body 1. An elastic washer 5 is fixedly connected between the air vent 3 and the insert 4. A fixing cylinder 8 is fixedly connected to the exterior of the atomizer body 1 and is sleeved on the outside of the insert 4. A sleeve 6 is fixedly connected to the exterior of the connecting tube body 2 and is inserted between the fixing cylinder 8 and the insert 4. A positioning hole 7 is provided on the exterior of the sleeve 6. Mounting seats 9 are fixedly connected to the upper and lower sides of the fixing cylinder 8. A positioning mechanism is installed inside the mounting seat 9. A quick-release mechanism is installed on the exterior of the atomizer body 1.

[0023] The outer surface of the connecting tube body 2 is threaded, and the insert 4 completely covers the air inlet 3. The connecting tube body 2 can be connected and installed with other structures such as oxygen masks through the threads.

[0024] The main body 2 of the connecting pipe abuts against the outside of the elastic gasket 5, and the elastic gasket 5 is in a compressed state. This compressed state ensures the airtightness of the connection and prevents gas leakage.

[0025] The main body of the connecting pipe 2, the vent 3, the insert 4, the elastic washer 5, the insert sleeve 6, and the fixing cylinder 8 are all coaxial ring structures. This coaxial design ensures smooth airflow and uniform force distribution.

[0026] The positioning mechanism includes a wedge block 10 and a compression spring 11. The wedge block 10 is slidably connected to the outside of the fixed cylinder 8, and the end of the wedge block 10 is located between the fixed cylinder 8 and the insertion tube 4. The wedge block 10 matches the positioning hole 7. The compression spring 11 is fixedly connected to the inside of the mounting base 9, and the other end of the compression spring 11 is fixedly connected to the outside of the wedge block 10. The elastic force of the compression spring 11 causes the wedge block 10 to automatically engage with the positioning hole 7 to achieve rapid locking.

[0027] The wedge block 10 has a bevel on one side of its end, and the bevel matches the insert 6. This bevel design allows the insert 6 to be easily pushed open by the wedge block 10 when it is inserted, thus achieving automatic guidance.

[0028] The quick-release mechanism includes a rotating rod 12 and a connecting rope 13. The rotating rod 12 is rotatably connected to the outside of the atomizer body 1 and is installed on one side of the insertion tube 4. The distance between the rotating rod 12 and the two sets of mounting seats 9 is equal. There are two sets of connecting ropes 13, which are fixedly connected to the outside of the rotating rod 12. The end of the connecting rope 13 passes through the outside of the mounting seat 9 and is fixedly connected to one side of the wedge block 10. The compression spring 11 is sleeved on the outside of the connecting rope 13. By rotating the rotating rod 12, the two sets of wedge blocks 10 can be pulled simultaneously to achieve quick unlocking.

[0029] The rotating rod 12 is externally fixedly connected to a screw block 14, which allows the user to apply force to rotate it and achieve one-handed operation.

[0030] The working principle of an atomizer connecting tube according to an embodiment is as follows: When the connecting tube body 2 is connected to the atomizer body 1, the operator first aligns the positioning hole 7 on the outside of the insert 6 with the mounting seats 9 on both sides of the fixed cylinder 8. Then, the connecting tube body 2 is pushed axially into the insert 4. During this process, the front end of the insert 6 contacts the inclined surface of the wedge block 10 inside the fixed cylinder 8. Under the action of axial thrust, the wedge block 10 is forced to slide into the fixed cylinder 8, while the compression spring 11 is compressed. As the insert 6 continues to penetrate deeper into the annular gap formed between the insert 4 and the fixed cylinder 8, the compression spring 11 is compressed. The wedge block 10 slides along the outer wall of the sleeve 6 until it is fully aligned with the positioning hole 7. At this time, the compression spring 11 releases the stored elastic potential energy, pushing the wedge block 10 to be precisely embedded in the positioning hole 7, forming a mechanical lock. At the same time, the end of the connecting tube body 2 continuously compresses the elastic washer 5, causing it to expand radially. This achieves both airtight sealing between the tube 4 and the sleeve 6 and, through the reverse elastic force of the elastic washer 5, causes the inner wall of the positioning hole 7 to be tightly abutted against the end of the wedge block 10, forming a double locking mechanism that effectively resists the risk of displacement caused by vibration or external impact.

[0031] When the connecting tube needs to be disassembled, the operator rotates the screw block 14 at the end of the rotating rod 12, causing the connecting rope 13 to tighten around the shaft. Simultaneously, the two sets of wedge blocks 10 overcome the resistance of the compression spring 11 and exit from the positioning hole 7. At this time, the elastic force accumulated by the elastic washer 5 pushes the connecting tube body 2 to move outward, so that the insert 6 automatically disengages from the annular gap between the insert 4 and the fixed cylinder 8, achieving tool-free quick separation. This design, through the elastic self-locking of the wedge block 10 and the positioning hole 7, the bidirectional sealing and elastic assistance of the elastic washer 5, and the linkage control of the rotating rod 12 and the connecting rope 13, significantly improves the disassembly and assembly efficiency while ensuring the connection stability. It is especially suitable for medical nebulization scenarios that require frequent replacement of connecting tubes or maintenance and cleaning.
