Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of humidifier cone head locking structures, and in particular to a humidifier cone head locking device. Background Art
[0002] In the medical field, the oxygen output from the gas source is usually relatively dry. The main function of an oxygen humidifier is to humidify dry oxygen. In the early days of oxygen therapy, there was no dedicated humidification device, and dry oxygen was delivered directly to the patient, which could easily cause dryness and discomfort in the patient's respiratory mucosa, and even cause respiratory damage. With the development of medical technology, humidifiers have gradually been applied to oxygen therapy. In addition to being used in common medical scenarios such as hospital wards and operating rooms, oxygen humidifiers are also required for portability in high-altitude operations and firefighting operations. For this reason, portable oxygen humidifiers have also emerged to meet the patient's need for oxygen humidification during oxygen therapy in different environments such as home and outdoors.
[0003] The cone of an oxygen humidifier can be connected to either the oxygen supply or the oxygen consumption port to allow the intake of dry oxygen or the exhaust of humidified oxygen to meet the user's needs. Traditional connection methods, such as threads, are relatively secure, but in practice, operators must manually rotate the cone of the humidifier or the corresponding connecting components to install and remove it. This process can be cumbersome due to the precision requirements of the threads and the limited space required for the rotation operation, wasting valuable time, especially in emergency situations.
[0004] The existing technology has not solved the above problems well, which has brought troubles to the normal work in this field. Therefore, a humidifier cone head locking device is urgently needed to solve the above problems. Utility Model Content

[0008] Optionally, a sliding member is further included, which is slidably arranged on the cylinder, the sliding member has a driving part, and the locking key has an unlocking part. After the sliding member slides, it is used to push the unlocking part. After the sliding member pushes the unlocking part, it is used to provide a force for the locking key to swing and release the locking part from the bottom surface of the clamping part.
[0009] Optionally, a limiting sleeve and a spring are further included. The limiting sleeve is detachably mounted on the cylinder, and both ends of the spring act on the limiting sleeve and the sliding member respectively to provide a force for the driving portion to move away from the unlocking portion.
[0010] Optionally, the cylinder body has an installation groove and a fixing groove, the installation groove is used to accommodate the limiting sleeve, and also includes a fixed opening ring, the fixed opening ring is detachably arranged in the fixing groove, and the fixed opening ring abuts against the limiting sleeve.

[0016] The working principle and beneficial effects of the utility model are as follows:
[0017] To use this humidifier cone locking device in a medical setting, first connect the connecting tube to the oxygen supply (such as the oxygen outlet near a hospital bed). Then prepare the connector, which connects to the oxygen humidifier. To install the oxygen humidifier on the device, insert the connector into the barrel. During insertion, the connector's locking portion contacts the locking portion of the locking key in the mounting hole on the barrel. Because the locking portion is made of elastically deformable plastic, the locking portion compresses the locking portion, causing it to deform outward, allowing the connector to be inserted smoothly into the barrel. Once the connector is properly inserted, the locking portion returns to its original shape and engages with the bottom surface of the locking portion, thus connecting the connector to the barrel and, in turn, the oxygen humidifier to the entire device. To disassemble the oxygen humidifier, simply swing the locking key. The locking portion moves with the swing of the locking key, releasing the locking portion from the bottom surface of the locking portion, allowing the connector to be removed from the barrel, completing the removal process.
[0018] In practice, unlike traditional threaded connections, operators don't need to spend a lot of time and effort manually rotating the humidifier cone or corresponding connecting parts to install and remove it. Whether in daily nursing care in hospital wards or in urgent and time-sensitive scenarios such as high-altitude operations and firefighting, this quick-plug locking method allows operators to quickly complete the installation and removal of oxygen humidifiers, greatly improving operational efficiency.
[0019] This solution is not only suitable for common medical settings such as hospital wards and operating rooms, but is also applicable to homes, outdoor environments, and specialized work environments (such as plateaus and firefighting) where portability is required. It can meet patients' oxygen humidification needs in various scenarios, providing greater convenience for medical work. This humidifier cone-shaped locking device eliminates the time-consuming and cumbersome operation associated with traditional connection methods, ensuring rapid deployment of the oxygen humidifier, buying more time for patient treatment and improving the timeliness and effectiveness of medical care.

Furthermore, to simplify the drawings and facilitate understanding, in some figures, only one of the components with the same structure or function is schematically shown or labeled. In this document, "one" not only means "only one" but also "more than one," and "several" includes "two" and "more than two."
[0031] It should be noted that, unless otherwise specified or limited, the terms "mounted," "connected," and "connected" should be understood broadly. For example, they can refer to fixed, detachable, or integral connections; mechanical or electrical connections; direct or indirect connections through an intermediary; and internal communication between two components. Those skilled in the art will understand the specific meanings of these terms in this utility model based on the specific circumstances.
[0032] In addition, in the description of the present application, the terms "first", "second", etc. are only used to distinguish the description and cannot be understood as indicating or implying relative importance.
[0033] Reference Figures 1 to 7 , which is the first embodiment of the present utility model, a humidifier cone head locking device is proposed, including a cylinder 1, a connecting pipe 2, a locking key 3 and a joint 4, the connecting pipe 2 is detachably connected to one end of the cylinder 1, the cylinder 1 has a mounting hole 5, the locking key 3 is swingably set in the mounting hole 5, the locking key 3 has a locking part 6, the locking part 6 can be elastically deformed, the joint 4 is detachably inserted into the other end of the cylinder 1, and the joint 4 has a clamping part 7, the clamping part 7 is used to squeeze and deform the locking part 6, and the locking part 6 is used to clamp the bottom surface of the clamping part 7 after it returns to its original shape. After the locking key 3 swings, it is used to release the clamping part 6 from the bottom surface of the clamping part 7.
[0034] In this embodiment, when using this humidifier cone locking device in a medical setting, first connect the connecting tube 2 to the oxygen supply port (e.g., the oxygen outlet near a hospital bed). Then, prepare the connector 4, which connects to the oxygen humidifier. To install the oxygen humidifier on the entire device, insert the connector 4 into the barrel 1. During insertion, the locking portion 7 of the connector 4 contacts the locking portion 6 of the locking key 3 within the mounting hole 5 on the barrel 1. Because the locking portion 6 is made of elastically deformable plastic, the locking portion 7 compresses the locking portion 6, causing it to deform outward, allowing the connector 4 to be smoothly inserted into the barrel 1. Once the connector 4 is properly inserted, the locking portion 6 returns to its original shape and engages with the bottom surface of the locking portion 7, thus connecting the connector 4 to the barrel 1 and completing the connection between the oxygen humidifier and the entire device. When the oxygen humidifier needs to be disassembled, it is only necessary to swing the locking key 3, and the locking portion 6 will move with the swing of the locking key 3, thereby releasing the clamping relationship with the bottom surface of the clamping portion 7, and the connector 4 can be pulled out of the cylinder 1, completing the disassembly process.
[0035] In practice, unlike traditional threaded connections, operators don't need to spend a lot of time and effort manually rotating the humidifier cone or corresponding connecting parts to install and remove it. Whether in daily nursing care in hospital wards or in urgent and time-sensitive scenarios such as high-altitude operations and firefighting, this quick-plug locking method allows operators to quickly complete the installation and removal of oxygen humidifiers, greatly improving operational efficiency.
[0036] This solution is not only suitable for common medical settings such as hospital wards and operating rooms, but is also applicable to homes, outdoor environments, and specialized work environments (such as plateaus and firefighting) where portability is required. It can meet patients' oxygen humidification needs in various scenarios, providing greater convenience for medical work. This humidifier cone-shaped locking device eliminates the time-consuming and cumbersome operation associated with traditional connection methods, ensuring rapid deployment of the oxygen humidifier, buying more time for patient treatment and improving the timeliness and effectiveness of medical care.
[0037] Furthermore, the locking portion 6 is in the shape of a bent hook, the bending direction of the locking portion 6 is toward the direction in which the joint 4 is inserted into the cylinder 1, the clamping portion 7 is a cone, and the locking portion 6 has a guide slope 8 on the side facing outside the cylinder 1 for contacting the conical surface of the clamping portion 7, and the locking portion 6 has a clamping plane 9 on the side facing inside the cylinder 1 for clamping with the bottom surface of the clamping portion 7.
[0038] In this embodiment, the clamping portion 7 is designed in the form of a cone. In the initial stage of insertion, the conical surface of the conical clamping portion 7 will contact the guiding inclined surface 8 of the locking portion 6 facing the outside of the cylinder 1. As the connector 4 continues to be inserted, the conical surface pushes the locking portion 6 along the guiding inclined surface 8. Since the locking portion 6 is in the shape of a bent hook, and the bending direction is toward the direction in which the connector 4 is inserted into the cylinder 1, this reserves space for the deformation of the locking portion 6. The locking portion 6 deforms outward under the pressure of the conical clamping portion 7. When the connector 4 is fully inserted into the cylinder 1, the bottom surface of the conical clamping portion 7 will contact the clamping plane 9 of the locking portion 6 facing the inside of the cylinder 1. At this time, the locking portion 6 returns to its original state, and the clamping plane 9 fits tightly with the bottom surface of the clamping portion 7, achieving a stable clamping connection, thereby firmly connecting the oxygen humidifier and the device. When disassembly is required, the locking key 3 is operated to move the locking portion 6 so that the clamping plane 9 is out of contact with the bottom surface of the clamping portion 7, and the connector 4 can be easily pulled out.
[0039] On the one hand, the clamping plane 9 on the inner side of the locking portion 6 contacts the bottom surface of the clamping portion 7. This plane-to-plane clamping method can provide a more stable connection. During the oxygen delivery process, it can effectively prevent the connection from being loosened due to equipment shaking or other external forces, ensuring that the connection between the oxygen humidifier and the equipment is firm and reliable, and ensuring the stable delivery of oxygen. On the other hand, during the installation process, the guiding slope 8 on the outside of the locking portion 6 cooperates with the conical surface of the cone clamping portion 7, which can play a good guiding role for the inserted connector 4, making it easier for the locking portion 6 to deform when the connector 4 is inserted, and can better adapt to the extrusion of the clamping portion 7, reducing component damage that may be caused by unreasonable deformation, and extending the service life of the device.
[0040] Furthermore, it also includes a sliding member 10, which is slidably arranged on the cylinder 1, and has a driving part 11 on the sliding member 10. The locking key 3 has an unlocking part 12. After the sliding member 10 slides, it is used to push the unlocking part 12. After the sliding member 10 pushes the unlocking part 12, it is used to provide a force for the locking key 3 to swing and release the locking part 6 from the bottom surface of the clamping part 7.
[0041] In this embodiment, during a medical operation, when the oxygen humidifier needs to be disassembled, that is, when the connector 4 needs to be pulled out from the barrel 1, the operator directly pinches the slider 10 with his hands. Then, the slider 10 slides in a direction away from the connector 4. During the sliding process, the driving portion 11 on the slider 10 contacts the unlocking portion 12 on the locking key 3, and as the slider 10 continues to slide, the driving portion 11 pushes the unlocking portion 12, pushing the locking key 3 to swing, and the swinging of the locking key 3 drives the locking portion 6 to move, thereby releasing the locking portion 6 from the bottom surface of the clamping portion 7. At the same time, due to the force generated by the sliding of the slider 10, the connector 4 can also be directly pulled out of the barrel 1, realizing a quick disassembly operation.
[0042] During the disassembly process, one only needs to simply pinch the slider 10 and slide it away from the connector 4 to complete a series of operations from undocking to removing the connector 4. Compared with the traditional complex disassembly method, this greatly simplifies the operation process and saves operation time. Whether in an emergency or in daily medical operations, it allows operators to complete their work more efficiently and realizes the function of quick plugging and unplugging. By pushing the unlocking part 12 through the slider 10, the locking key 3 swings and the process of undoing the docking is completed in one go, and the connector 4 can also be pulled out of the barrel 1. This efficient disassembly method reduces the time for equipment maintenance and replacement and improves the efficiency of medical equipment use.
[0043] Furthermore, it also includes a limit sleeve 13 and a spring 14. The limit sleeve 13 is detachably arranged on the cylinder 1, and the two ends of the spring 14 act on the limit sleeve 13 and the sliding member 10 respectively to provide a force for the driving part 11 to move away from the unlocking part 12.
[0044] In this embodiment, a limiting sleeve 13 is mounted on the barrel 1, and a spring 14 is positioned between the limiting sleeve 13 and the slider 10. Due to the action of the spring 14, the driving portion 11 on the slider 10 moves away from the unlocking portion 12 and abuts against the rear side of the locking portion 6. When the connector 4 is connected to the barrel 1, the connector 4 is inserted into the barrel 1. At this time, the locking portion 7 of the connector 4 presses against the front side of the locking portion 6. Because the driving portion 11 abuts against the rear side of the locking portion 6, the locking portion 6 only deforms and does not swing, ensuring that the locking portion 6 can be stably engaged with the locking portion 7. When the connector 4 needs to be disassembled, the slider 10 is pushed against the elastic force of the spring 14, causing the driving portion 11 to push the unlocking portion 12 of the locking key 3, thereby releasing the engagement. When the operation is completed, the slider 10 quickly returns to its original position under the elastic force of the spring 14, and the driving portion 11 returns to a position away from the unlocking portion 12.
[0045] During the insertion of connector 4, the elastic force of spring 14 causes drive portion 11 to abut against the rear side of locking portion 6, limiting the swing of locking portion 6. This allows locking portion 6 to deform only to accommodate the clamping portion 7 when squeezed, avoiding the unstable clamping caused by the swing of locking portion 6. This ensures a stable locking effect every time the clamping is engaged, improving the reliability of the device connection. Spring 14 allows slider 10 to quickly return to its original position after the operation is completed, preparing for the next operation. This eliminates the need for the operator to manually adjust the position of slider 10, reducing the number of steps required, making the device more convenient and efficient to use, and improving work efficiency.
[0046] Furthermore, the cylinder body 1 has an installation groove 15 and a fixing groove 16 . The installation groove 15 is used to accommodate the limiting sleeve 13 . It also includes a fixing open ring 17 . The fixing open ring 17 is detachably arranged in the fixing groove 16 . The fixing open ring 17 abuts against the limiting sleeve 13 .
[0047] In this embodiment, during assembly, first place the stopper sleeve 13 in the mounting groove 15 of the barrel 1. Next, pick up the fixed split ring 17. Since it has an opening, it can be broken open and placed in the fixed groove 16 of the barrel 1. The ring is then returned to its original position. At this point, the fixed split ring 17 abuts the stopper sleeve 13, thereby firmly pressing the stopper sleeve 13 into the mounting groove 15.
[0048] The abutment and fixation of the retaining sleeve 13 by the fixed split ring 17 ensures a more secure installation of the retaining sleeve 13 on the cylinder 1. During use, the retaining sleeve 13 will not easily shift even if subjected to external vibrations, collisions, and other factors. The design of the fixed split ring 17 simplifies and facilitates installation, eliminating the need for complex installation tools and tedious installation steps, improving assembly efficiency and saving installation time.
[0049] Furthermore, the sliding member 10 has a baffle 18 , and the limiting sleeve 13 has a baffle 2 19 . The baffle 18 and the baffle 2 19 are staggered and arranged to shield the spring 14 .
[0050] In this embodiment, baffles 18 on the slider 10 and baffles 19 on the retaining sleeve 13 are arranged in an interlaced manner. During use, whether the operator is sliding the slider 10 or the device is at rest, the interlaced arrangement of baffles 18 and 19 prevents interference between them. Furthermore, when viewed from the outside, the spring 14 and the locking key 3 are obscured by baffles 18 and 19, obscuring the complex internal structure of the spring 14 and the locking key 3.
[0051] Baffle 18 and baffle 2 19 effectively shield the spring 14 and locking key 3. From a safety perspective, they prevent direct contact between the spring 14 and locking key 3 and reduce the potential for damage from collisions, dust, and debris, thereby protecting key internal components. Aesthetically, they conceal the complex internal structure, making the entire device appear neater and more aesthetically pleasing, enhancing its appearance.
[0052] Furthermore, the driving portion 11 is arc-shaped.
[0053] In this embodiment, the arc-shaped driving portion 11 can achieve a smooth transition when contacting the unlocking portion 12. This reduces friction and resistance during contact, allowing the driving portion 11 to push the unlocking portion 12 more smoothly, ensuring the consistency and efficiency of the disassembly operation, and preventing operation failures or delays due to unsmooth contact.
[0054] Furthermore, the sliding member 10 has anti-slip grooves 20 .
[0055] In this embodiment, the anti-slip grooves 20 provided on the slider 10 generate significant friction when the fingers come into contact with the anti-slip grooves 20. Whether in a dry environment or with a slight amount of sweat on the hands, the anti-slip grooves 20 ensure a more secure grip on the slider 10, preventing the fingers from slipping easily when pushing the slider 10 for operation. This reduces operational errors and improves the accuracy and success rate of operations.
[0056] Furthermore, a sealing ring 21 is included. The sealing ring 21 is provided in the connecting pipe 2 and is used to abut against the circumferential surface of the joint 4.
[0057] In this embodiment, a sealing ring 21 is provided on the inner wall of the connecting tube 2. When the connector 4 is inserted into place, the sealing ring 21 deforms to a certain extent under the pressure of the circumferential surface of the connector 4, thereby tightly abutting the circumferential surface of the connector 4. During the process of oxygen being transported through the device, the sealing ring 21 can effectively fill the small gap between the circumferential surface of the connector 4 and the inner wall of the connecting tube 2, improving the sealing between the connector 4 and the connecting tube 2, preventing oxygen from leaking from the connection between the connector 4 and the connecting tube 2 during the transmission process, and ensuring that oxygen can be transmitted efficiently and stably through the device.
[0058] Furthermore, the connecting pipe 2 and the cylinder 1 are threadedly connected.
[0059] In this embodiment, the threaded connection provides a strong connection force, making the connection between the connecting tube 2 and the barrel 1 more stable. In complex use environments, such as medical scenarios where the device may be moved or bumped, this stable connection ensures that the overall structure of the device will not easily loosen or separate, ensuring the stability and reliability of the device and reducing the probability of equipment failure caused by loose components.
