Description

Technical Field

[0001] This utility model relates to the field of atomizer nozzle technology, and in particular to an adjustable atomizer nozzle. Background Technology

[0002] Medical nebulizers are widely used in healthcare, particularly in the treatment of respiratory diseases such as asthma, chronic obstructive pulmonary disease (COPD), and other respiratory infections. Nebulizers deliver medication directly to the patient's lungs, providing rapid therapeutic effects. However, existing medical nebulizers typically have a fixed particle size, which limits their adaptability to different patients and conditions. Since inhalation capacity and lung absorption vary significantly among patients, nebulizers with fixed particle sizes cannot provide optimal therapeutic effects for all patients. For example, children and elderly patients may require smaller drug particles for easier inhalation. Therefore, an adjustable nebulizer nozzle is proposed to address these issues. Utility Model Content

[0004] This utility model adopts the following technical solution: an adjustable atomizer nozzle, including a body, a cover threaded to the top of the body, a base fixedly installed at the bottom of the body, a pipe connector fixedly installed on the side of the body, a guide tube fixedly installed on the surface of the pipe connector, a limiting shell fixedly installed at the end of the guide tube, a through hole through the surface of the limiting shell, a nozzle fixedly installed on the side of the limiting shell away from the guide tube, a face mask fixedly installed on the surface of the nozzle, a rotating plate rotatably connected inside the limiting shell, an atomizing spray net fixedly installed on the surface of the rotating plate, a housing fixedly installed on the surface of the limiting shell, a first rotating shaft rotatably connected between the rotating plate and the housing, a driven gear fixedly installed on the surface of the first rotating shaft, a second rotating shaft rotatably connected between the limiting shell and the housing, a driving gear fixedly installed on the surface of the second rotating shaft.

[0005] Preferably, the atomizing spray net corresponds to the position of the through hole, and the conduit and nozzle are respectively connected to both sides of the through hole. This allows the liquid to be effectively atomized through the spray net and sprayed out through the nozzle.

[0006] Preferably, the number of atomizing spray nets is six, and the six groups of atomizing spray nets are circumferentially distributed on the surface of the rotating plate. The spray holes on the atomizing spray nets are of different diameters. This allows personnel to select different spray effects to meet different needs, such as fine mist or coarse mist, adapting to different usage scenarios.

[0007] Preferably, the driving gear and the driven gear are meshed, and an adjustment groove is provided on the side of the housing near the driving gear, with the driving gear located inside the adjustment groove. Here, the driving gear can be easily rotated by a person through the adjustment groove, allowing for selective adjustment of the atomizing spray net on the rotating plate through the interaction of the driving gear and the driven gear.

[0008] Preferably, a limiting arc plate is installed on the surface of the adjusting groove, and a locking tooth block is fixedly installed inside the limiting arc plate. The locking tooth block engages with the tooth groove of the driving gear. Sliding seats are fixedly installed on both sides of the adjusting groove. A slider is fixedly installed on the surface of the limiting arc plate. A fixing plate is fixedly installed on the surface of the housing. A pull rod is fixedly installed on the side of the limiting arc plate near the fixing plate. A spring is sleeved on the surface of the pull rod, and a pull plate is fixedly installed at the end of the pull rod. The pull rod slides inside the fixing plate. Here, by cooperating with the driving gear through the limiting arc plate and the locking tooth block, the position of the driving gear can be locked, preventing accidental deflection of the rotating plate.

[0009] Preferably, a fixing plate is fixedly installed on the surface of the conduit near the pipe fitting, and a locking block is fixedly installed on the surface of the fixing plate. A locking groove is formed on the surface of the pipe fitting. A insertion tube is fixedly installed on the side of the fixing plate that contacts the pipe fitting, and the insertion tube is inserted into the pipe fitting. A tightening cap is rotatably connected to the surface of the conduit, and a limit bracket is fixedly installed on the surface of the tightening cap. The tightening cap is threadedly connected to the surface of the pipe fitting. This provides a convenient method for assembling and disassembling the conduit and pipe fitting, while also providing bending protection at the connection point.

[0010] Preferably, a rotating sleeve is rotatably connected to the side end of the limiting frame, and the rotating sleeve is fitted onto the surface of the conduit. Here, the cooperation between the rotating sleeve and the limiting frame provides convenience for the use of the conduit and avoids friction when handling the conduit.

[0011] Compared with the prior art, the advantages and positive effects of this utility model are as follows:

[0012] 1. In this utility model, the rotating plate is provided with six sets of atomizing spray nets with different apertures. Through the meshing transmission of the driving gear and the driven gear, combined with the position adjustment of the driving gear in the adjustment groove, the selection and adjustment of the atomizing spray net can be easily realized. Through the cooperation of the limiting guard plate and its inner locking tooth block, under the synergistic action of the pull plate, pull rod and spring, the position of the driving gear can be locked to ensure the stability of the gear position during the adjustment process, thereby preventing the change of atomization effect due to misoperation.

[0013] 2. In this utility model, rotating the limiting frame causes the tightening cap to loosen from the pipe joint. Then, the tightening cap is moved away from the pipe joint, and the conduit is rotated at the same time to make the locking block contact and lock with the locking groove. Then, the insertion tube on the conduit is pulled out from inside the pipe joint, which makes it easy for personnel to remove the conduit and replace it. Attached Figure Description

There are six sets of atomizing spray nets 19, which are circumferentially distributed on the surface of the rotating plate 18. The spray holes on the atomizing spray nets 19 are of different diameters, allowing personnel to select different spray effects to meet different needs, such as fine mist or coarse mist, and adapt to different usage scenarios. The driving gear 23 and the driven gear 21 are meshed. An adjustment groove 24 is provided on the side of the housing 17 near the driving gear 23. The driving gear 23 is located inside the adjustment groove 24. Through the adjustment groove 24, personnel can easily rotate the driving gear 23 so that the atomizing spray net 19 on the rotating plate 18 can be selectively adjusted in cooperation with the driven gear 23 and the driven gear 21.

[0026] Example 2

[0027] Please see Figure 2 and Figure 6A limiting arc plate 27 is installed on the surface of the adjusting groove 24. A locking tooth block 29 is fixedly installed inside the limiting arc plate 27. The locking tooth block 29 engages with the tooth groove of the driving gear 23. Slide seats 25 are fixedly installed on both sides of the adjusting groove 24. A slider 28 is fixedly installed on the surface of the limiting arc plate 27. A fixing plate 26 is fixedly installed on the surface of the housing 17. A pull rod 30 is fixedly installed on the side of the limiting arc plate 27 near the fixing plate 26. A spring 31 is sleeved on the surface of the pull rod 30. A pull plate 32 is fixedly installed at the end of the pull rod 30. The pull rod 30 slides inside the fixing plate 26. Through the cooperation of the limiting arc plate 27 and the locking tooth block 29 with the driving gear 23, the adjusting groove 24 can be adjusted. The position of the drive gear 23 is locked to prevent the rotating plate 18 from deflecting due to misoperation. A fixing plate 7 is fixedly installed on the side of the conduit 6 near the pipe connector 4. A locking block 8 is fixedly installed on the surface of the fixing plate 7. A locking groove 5 is opened on the surface of the pipe connector 4. A plug tube 9 is fixedly installed on the side of the fixing plate 7 that contacts the pipe connector 4.

[0028] Working principle: During the use of the atomizer, if it is necessary to adjust the nozzle 15 to control the spray size, pull the pull plate 32. The pull plate 32 drives the pull rod 30 to slide inside the fixed plate 26. At the same time, the pull rod 30 drives the limiting arc plate 27 to move off the driving gear 23, causing the locking tooth block 29 on the inner side of the limiting arc plate 27 to disengage from the tooth groove of the driving gear 23. During this process, the spring 31 on the surface of the pull rod 30 will be squeezed by the limiting arc plate 27 and the fixed plate 26. Then, through the adjustment groove 24, the operator can easily and quickly rotate the driving gear 23. The driving gear 23 drives the driven gear 21 to rotate. 1 drives the first rotating shaft 20 to rotate, thereby driving the rotating plate 18 to rotate inside the limiting shell 13. Different aperture atomizing spray nets 19 can be selected. After adjustment, the pull plate 32 is released. Under the elastic force of the spring 31, the limiting arc plate 27 automatically resets, thereby locking the drive gear 23 again. If the guide tube 6 needs to be replaced, the limiting frame 11 is rotated. The limiting frame 11 drives the tightening cap 10 to loosen from the pipe joint 4. Then the tightening cap 10 is moved away from the pipe joint 4, and the guide tube 6 is rotated at the same time to make the locking block 8 contact and lock with the locking groove 5. Then the insertion pipe 9 on the guide tube 6 is pulled out from inside the pipe joint 4, so that the guide tube 6 can be easily removed by personnel.

[0029] The above description is merely a preferred embodiment of the present utility model and is not intended to limit the present utility model in any other way. Any person skilled in the art may make changes or modifications to the above-disclosed technical content to create equivalent embodiments for application in other fields. However, any simple modifications, equivalent changes, and modifications made to the above embodiments based on the technical essence of the present utility model without departing from the technical solution of the present utility model shall still fall within the protection scope of the technical solution of the present utility model.
