Description

Technical Field

[0001] This invention belongs to the technical field of nebulizers, specifically relating to a nebulizer for pediatric clinical use. Background Technology

[0002] A nebulizer consists of a nebulizer main unit, a nebulizer cup, an air tube, an airflow duct, an inhalation port or mask, and a control panel. To use it, connect the tube on the nebulizer cup to the tube on the nebulizer main unit, add the medication to the nebulizer cup, turn on the nebulizer main unit, operate the nebulizer main unit through the control panel, and finally put on the mask to achieve nebulization.

[0003] Existing atomizers have the following two drawbacks in use: 1. When the atomizer is not in use, the tubes on the atomizer are exposed, and dust and other particles will inevitably enter the tubes. When used later, dust is easily mixed into the atomization, which will affect the atomization effect. Although the tubes on the atomizer main unit can be blocked with a sealing plug, the sealing plug needs to be pulled out separately each time, which is cumbersome. Moreover, the sealing plug is easy to be lost due to rolling.

[0004] 2. When connecting the pipes, directly insert the pipe on the atomizing cup into the pipe on the atomizer main unit and limit the movement using a damping method. This method can limit the movement for adults, but in pediatrics, children wearing masks may struggle due to discomfort, which may cause pulling at the pipe connection point and easily cause the pipe on the atomizing cup to detach from the pipe on the atomizer main unit, affecting the atomization process. Summary of the Invention

[0005] The purpose of this invention is to provide a nebulizer for pediatric clinical use, which aims to solve the problems mentioned in the background art.

[0011] As a preferred embodiment of the pediatric clinical nebulizer of the present invention, the limiting component includes a T-shaped plate slidably connected in the strip-shaped opening, the T-shaped plate is provided with a sliding groove, a movable block is slidably connected in the sliding groove, the movable block is elastically connected to the inner wall of the sliding groove by a second spring, a lever is fixedly connected to the movable block, and the outer expansion groove is provided with a first guide groove, a second guide groove, a third guide groove, a fourth guide groove, and a fifth guide groove that cooperate with the lever and are connected end to end.

[0012] As a preferred embodiment of the nebulizer for pediatric clinical use of the present invention, the connection between the third guide groove and the fourth guide groove forms an inward concave arc edge, and a triangular block is fixedly connected inside the third guide groove, with the uppermost vertex of the triangular block located on the right side of the inward concave arc edge.

[0013] As a preferred embodiment of the pediatric clinical nebulizer of the present invention, the guide assembly includes a first vertical groove disposed on a fixed plate, the first vertical groove being connected to a first inclined groove, the first inclined groove being connected to a second vertical groove, the second vertical groove being connected to the first vertical groove through the second inclined groove, the second inclined groove being completely inside the first inclined groove, and a guide rod that cooperates with the first vertical groove, the second vertical groove, the first inclined groove, and the second inclined groove being fixedly connected to the side wall of the connecting rod.

[0015] As a preferred embodiment of the nebulizer for pediatric clinical use of the present invention, the distance from the connection point of the first vertical groove and the second inclined groove to the end of the first vertical groove near the main unit pipe is greater than the radius of the main unit pipe.

[0016] Compared with the prior art, the beneficial effects of the present invention are: 1. By setting up a shielding mechanism and an opening mechanism, the main unit's pipes can be automatically sealed when the atomizer is not in use, thereby preventing dust from entering and not affecting the subsequent atomization process. When the main unit's pipes need to be used, simply press the T-shaped plate to automatically open the cover, facilitating the connection between pipes.

[0017] 2. By setting up a reinforcement mechanism, after pressing the T-shaped plate to open the cover plate and releasing the T-shaped plate, the cover plate can move automatically, so that the cover plate is fixed on the outside of the pressing head to block the external pipe and prevent the external pipe from loosening due to pulling, thus ensuring the stability of the connection between the main unit pipe and the external pipe.

[0021] To make the above-mentioned objects, features and advantages of the present invention more apparent and understandable, the specific embodiments of the present invention will be described in detail below with reference to the accompanying drawings.

[0022] Reference Figure 1 - Figure 7This invention provides a nebulizer for pediatric clinical use, which achieves dust prevention for the main unit tube 12 of the nebulizer host 10 and allows for quick opening of the main unit tube 12 during use. The nebulizer host 10 includes an opening 11 within which the main unit tube 12 is located. An external tube 13 is located at the front of the main unit tube 12, and a pressing head 14 is mounted on the external tube 13. Multiple fan-shaped cover plates 15 are located at the front of the main unit tube 12. The multiple cover plates 15, when moved, block the main unit tube 12, thus preventing dust accumulation. The opening mechanism includes a rotating external toothed ring 20 connected to the main unit tube 12, with cover plates mounted on the external toothed ring 20. The opening 11 has a guide component 21 that provides power for the movement of the cover plate 15. The inner wall of the opening 11 is provided with an elastic component 22 that provides power for the reset of the outer toothed ring 20. The inner wall of the opening 11 is connected to an L-shaped groove 23. The L-shaped groove 23 is provided with a pulling component 24 that provides power for the rotation of the outer toothed ring 20. The L-shaped groove 23 is provided with an outward expansion groove 25. The outward expansion groove 25 is provided with a strip-shaped opening 26 that penetrates the atomizer host. The strip-shaped opening 26 is provided with a limiting component 27 that prevents the cover plate 15 from automatically resetting after being opened. The reinforcement mechanism includes a fixing plate 30 that is fixedly connected to the inner wall of the opening 11. The fixing plate 30 is provided with a guide component 31 and a one-way component 32 that prevent the external pipe 13 from loosening when connected to the host pipe 12.

[0023] The external pipe 13 is connected to the atomizing cup, which is equipped with an atomizing cover or atomizing nozzle. The atomizing cover or nozzle is for children to use. To use, connect the main unit pipe 12 to the external pipe 13, add the medicine to the atomizing liquid container, and then turn on the atomizer main unit 10. Multiple covers 15 are used to seal the front end of the main unit pipe 12. A control panel is also set on the back of the atomizer main unit 10 for controlling the main unit. This is existing technology and will not be described in detail here.

[0024] Furthermore, the guide assembly 21 includes multiple arc-shaped openings 211 disposed on the outer toothed ring 20. A circular ring 212 is fixedly connected inside the opening 11. The circular ring 212 is provided with multiple support openings 213. An installation cylinder 214 is provided inside the arc-shaped opening 211, penetrating through the support opening 213 and with its upper end open to 11. A connecting rod 215 is provided inside the installation cylinder 214 and is fixedly connected to the cover plate 15. Multiple cover plates 15 are combined to form a disc with a diameter larger than the outer diameter of the main unit pipe 12. The number of arc-shaped openings 211 is equal to the number of cover plates 15. The distance between the inner wall of the arc-shaped opening 211 and the main unit pipe 12 increases sequentially in the clockwise direction along the outer toothed ring 20; the elastic component 22 includes a T-shaped expansion groove 221 disposed on the inner wall of the opening 11, the ring 212 is provided with an installation port communicating with the support port 213, a T-shaped push plate 222 passing through the installation port is slidably connected in the expansion groove 221, a guide block 223 fixed to the cylinder is fixedly connected on the push plate 222, and the push plate 222 is elastically connected to the inner wall of the expansion groove 221 through the first spring 224.

[0025] The guide block 223 can also be equipped with an anti-detachment block, and an anti-detachment groove is provided on the inner wall of the support port 213 to prevent the guide block 223 from detaching from the support port 213 when it moves. The distance between the inner wall of the arc-shaped port 211 and the main unit pipe 12 increases sequentially in the clockwise direction along the outer toothed ring 20. As the outer toothed ring 20 rotates counterclockwise around the main unit pipe 12, it drives the mounting cylinder 214 to move outward in the support port 213, causing multiple cover plates 15 to open.

[0026] Preferably, the pulling assembly 24 includes a toothed plate 241 slidably connected within an L-shaped groove 23 and meshing with the outer toothed ring 20; a T-shaped block 242 is slidably connected within the L-shaped groove 23; a steel wire rope 243 fixedly connected to the T-shaped block 242 and fixed to the toothed plate 241; and a guide wheel 244 for guiding the steel wire rope 243 is provided within the L-shaped groove 23. The limiting assembly 27 includes a T-shaped plate 271 slidably connected within a strip-shaped opening 26; a sliding groove 272 is provided on the T-shaped plate 271; and a moving block 273 is slidably connected within the sliding groove 272. Block 273 is elastically connected to the inner wall of slide groove 272 via a second spring. A lever 274 is fixedly connected to the movable block 273. The outer expansion groove 25 is provided with a first guide groove 275, a second guide groove 276, a third guide groove 277, a fourth guide groove 278, and a fifth guide groove 279 that cooperate with the lever 274 and are connected end to end. The connection between the third guide groove 277 and the fourth guide groove 278 forms an inward concave arc edge. A triangular block is fixedly connected in the third guide groove 277, and the uppermost vertex of the triangular block is located on the right side of the inward concave arc edge.

[0027] It should be noted that the length of the toothed plate 241 is less than the length of the transverse side of the L-shaped groove 23, allowing the toothed plate 241 to slide within the L-shaped groove 23. The guide wheel 244 guides the wire rope 243, preventing it from shifting. The moving block 273 prevents the lever 274 from getting stuck. A triangular block is fixedly connected within the third guide groove 277, with the uppermost vertex of the triangular block located on the right side of the concave arc edge, ensuring that the lever 274 moves straight during a second push. Instead of resetting to the first guide groove 275 along the third guide groove 277, the lever 274 moves directly into the fourth guide groove 278. The lower side wall at the connection between the first guide groove 275 and the fifth guide groove 279 can also be set in this way to ensure that when the lever 274 moves downward, it moves directly into the first guide groove 275. Here, the vertical side depth of the L-shaped groove 23 is less than the horizontal side depth of the L-shaped groove 23. The inner end of the T-shaped block 242 slides in the L-shaped groove 23, and the outer end of the T-shaped block 242 extends into the outward expansion groove 25 and abuts against the T-shaped plate 271.

[0028] When in use, without opening the atomizer main unit 10, multiple cover plates 15 abut against the front wall of the main unit pipe 12, sealing the front end of the main unit pipe 12. When it is necessary to connect the main unit pipe 12 to the external pipe 13, press the T-shaped plate 271, causing the T-shaped plate 271 to move downwards, causing the T-shaped block 242 to move downwards, thereby pulling the steel wire rope 243 downwards, driving the toothed plate 241 to move to the right, causing the outer toothed ring 20 to rotate counterclockwise (viewed from the direction directly facing the main unit pipe 12, the same below). When the outer toothed ring 20 rotates, the arc-shaped opening 211 moves, and the distance between the inner wall of the arc-shaped opening 211 and the main unit pipe 12 increases sequentially along the clockwise direction of the outer toothed ring 20. Therefore, when the outer toothed ring 20 rotates counterclockwise... The mounting cylinder 214 can be moved outward, the connecting rod 215 can be moved outward, and the cover plate 15 can be moved outward to open the main unit pipe 12. When the mounting cylinder 214 moves, the guide block 223 slides in the support port 213 to guide the mounting cylinder 214. When the guide block 223 moves, it can drive the push plate 222 to move, so that the first spring 224 can extend and retract to reset the push plate 222 and drive the guide block 223 to reset. Here, the arc-shaped port 211 drives the mounting cylinder 214 to move a sufficient distance to ensure that the cover plate 15 will not affect the docking of the main unit pipe 12 and the external pipe 13 after it is opened. A reset spring is also provided between the connecting rod 215 and the inner wall of the mounting cylinder 214 to help the connecting rod 215 reset. When the T-shaped plate 271 moves downward, the lever 274 moves downward. The lever 274 first moves within the first guide groove 275, and then moves to the connection point of the second guide groove 276. Here, at the connection point of the second guide groove 276 and the third guide groove 277, a triangular block can also be set so that the lever 274 moves into the third guide groove 277 instead of resetting from the second guide groove 276. Then, the lever 274 moves to the concave arc edge at the connection point of the fourth guide groove 278 and the third guide groove 277. At this time, because the concave arc edge blocks the lever 274 from resetting upward, the moving block 273 is kept from resetting upward, ensuring that the T-shaped plate 271 does not reset upward. The T-shaped block 242 cannot reset automatically. Through transmission, the open state of the cover plate 15 is maintained, preventing the cover plate 15 from squeezing the external pipe 13. It is worth noting that when the lever 274 moves, the moving block 273 slides within the slide groove 272 for guidance, preventing the lever 274 from getting stuck. In addition to the phenomenon of dwelling, when the lever 274 moves from the second guide groove 276 to the connection between the third guide groove 277 and the fourth guide groove 278, the T-shaped plate 271 will reset slightly. At this time, the external gear ring 20 will also reset slightly. Here, the external gear ring 20 is set so that after the reset, the position of the cover plate 15 will not affect the installation of the external pipe 13. That is, the side wall of the external pipe 13 will not abut against the cover plate 15. When the cover plate 15 needs to be reset, simply press the T-shaped plate 271 again, so that the lever 274 moves from the connection between the third guide groove 277 and the fourth guide groove 278 to the fourth guide groove 278. After releasing the T-shaped plate 271, the lever 274 resets to the connection between the first guide groove 275 and the fifth guide groove 279 via the fifth guide groove 279. At this time, the T-shaped plate 271 will reset upward, the T-shaped block 242 can reset, the external gear ring 20 resets, and the cover plate 15 will once again cover the front end of the main unit pipe 12.

[0029] In summary, by setting up an opening mechanism and a blocking mechanism, when the atomizer host 10 is not in use, the host pipe 12 on the atomizer host 10 is automatically sealed to prevent dust from entering. At the same time, when the host pipe 12 needs to be used, simply move the T-shaped plate 271, and multiple cover plates 15 can be opened through transmission, which facilitates the connection between the host pipe 12 and the external pipe 13.

[0030] Reference Figure 1 - Figure 7This invention provides a reinforcement mechanism for pediatric clinical nebulizers, solving the problem of preventing the external pipe 13 from loosening when it is connected to the main unit pipe 12. It includes a guide assembly 31, comprising a first vertical groove 311 disposed on a fixing plate 30, a first inclined groove 312 connected to the first vertical groove 311, a second vertical groove 313 connected to the first inclined groove 312, and a second inclined groove 314 connecting the second vertical groove 313 to the first vertical groove 311. 314 is completely inside the first inclined groove 312. The connecting rod 215 is fixedly connected to the side wall of the connecting rod 215, which cooperates with the first vertical groove 311, the second vertical groove 313, the first inclined groove 312, and the second inclined groove 314. The one-way component 32 includes a square groove 321 disposed on the inner wall of the first inclined groove 312 and the second inclined groove 314. A wedge block 322 is slidably connected in the square groove 321. The wedge block 322 is elastically connected to the inner wall of the square groove 321 through a third spring 323.

[0031] Specifically, the wedge block 322 in the first inclined groove 312 has its inclined edge facing the first inclined groove 312, and the wedge block 322 in the second inclined groove 314 has its inclined edge facing the second inclined groove 314. Thus, when moving in the first vertical groove 311, the guide rod 315 moves into the first inclined groove 312 instead of the second inclined groove 314. And when resetting, the guide rod 315 cannot reset from the first inclined groove 312 into the first vertical groove 311. It is worth noting that after the external pipe 13 is connected to the main pipe 12, the external pipe 13 will extend to the inner end of the opening 11. At this time, there will be a gap between the pressing head 14 and the front end face of the main pipe 12, so the cover plate 15 needs to move a certain distance towards the inner end of the opening 11.

[0032] During use, when the installation cylinder 214 moves, it drives the guide block 223 to move outward along the support opening 213, which in turn drives the connecting rod 215 to move outward. At this time, the guide rod 315 slides in the first vertical groove 311. When the lever 274 moves from the first guide groove 275 to the connection between the second guide groove 276 and the third guide groove 277, the guide rod 315 moves from the first vertical groove 311 to the first inclined groove 312 until it moves to the connection between the second vertical groove 313 and the first inclined groove 312. During this process, the cover plate 15 first moves to the outside of the main unit pipe 12, and then moves towards the inside of the opening 11. The cover plate 15 opens outwards, and then the external pipe 13 is inserted into the main unit pipe 12. At this time, the rear side wall of the cover plate 15 is flush with the front side wall of the press head 14. Then, when the lever 274 moves from the connection point of the second guide groove 276 and the third guide groove 277 to the connection point of the third guide groove 277 and the fourth guide groove 278, the external toothed ring 20 will reset a small section, causing the mounting cylinder 214 to reset a small section, and the connecting rod 215 to reset a small section, causing the rear side wall of the cover plate 15 to abut against the front side wall of the press head 14, preventing the main unit pipe 12 from separating from the external pipe 13, and avoiding damage to the main unit pipe due to the external pipe 13 being pulled. When the connection between pipe 12 and external pipe 13 becomes loose, the guide rod 315 cannot return from the second vertical groove 313 to the first vertical groove 312 because the inclined edge of the wedge block 322 in the first inclined groove 312 faces the first vertical groove 312. Instead, it slides in the second vertical groove 313, thus preventing the position of the cover plate 15 from changing in the front-back direction. When the mounting cylinder 214 returns to its original position, the guide rod 315 moves from the second vertical groove 313 to the second inclined groove 314, and finally returns to its original position via the first vertical groove 311, covering the main pipe 12 again. It is worth noting that when disassembling the external pipe 13, the T-shaped plate 271 should be pressed first to make... When lever 274 moves to the connection between the fourth guide groove 278 and the fifth guide groove 279, the cover plate 15 separates from the pressing head 14. Then, after pulling out the external pipe 13, the T-block 242 is released and reset. It is worth noting that when guide rod 315 moves to the connection between the second inclined groove 314 and the first vertical groove 311, cover plate 15 is still outside the main pipe 12 to avoid jamming. When guide rod 315 moves to the connection between the second inclined groove 314 and the first vertical groove 311, the rear side wall of cover plate 15 is flush with the front side wall of main pipe 12 to ensure that cover plate 15 can cover main pipe 12.

[0033] In summary, by setting up a reinforcement mechanism, the front and rear positions of the cover plate 15 can be changed during the movement of the cover plate 15, so that the cover plate 15 can lock the pressing head 14 from the front end, preventing the external pipe 13 from separating due to pulling, and ensuring the stability of the connection between the main unit pipe 12 and the external pipe 13.

[0034] It should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention and are not intended to limit it. Although the present invention has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can be made to the technical solutions of the present invention without departing from the spirit and scope of the technical solutions of the present invention, and all such modifications or substitutions should be covered within the scope of the claims of the present invention.
