Description

Technical Field

[0001] This invention relates to the field of nasal irrigator nozzles, and more particularly to a multi-purpose nasal irrigator nozzle. Background Technology

[0002] During respiration, impurities and harmful substances in the air are filtered by the nasal cavity and prevented from entering the lungs. However, if these impurities and harmful substances are not cleaned in time and remain in the nasal cavity for a long time, they may breed more bacteria and cause nasal diseases. Currently, the nozzles of nasal irrigators on the market are only suitable for a limited range of people, and infants and children have poor acceptance of existing nasal irrigators. At the same time, due to the limitations of current manufacturing precision and structural design, the atomized particles of the medicine produced by existing nozzles are relatively large and cannot reach the lower respiratory tract, resulting in poor treatment effects. Summary of the Invention

[0003] This invention aims to solve the above problems and provides a multi-purpose nasal irrigator nozzle, the technical solution of which is as follows:

[0004] A multi-purpose nasal irrigator nozzle includes a nozzle base, a nozzle core rod, a nozzle, and a nipple cap. The nozzle base includes a fixed base and a movable cover that rotate relative to each other. A spray rod is disposed on the side of the movable cover facing the fixed base, and a spray rod outlet is provided on the movable cover, which communicates with the inner cavity of the spray rod. A mounting core rod is fixedly disposed on the upper surface of the movable cover. The nozzle core rod is sleeved on the outside of the mounting core rod, and the nozzle is sleeved on the outside of the nozzle core rod. A nozzle outlet is provided at the top of the nozzle, and a flow guiding channel is provided on the nozzle core rod to communicate with the spray rod outlet and the nozzle outlet. The nipple cap is detachably sleeved on the upper part of the outer side of the nozzle, and a nipple outlet is provided at the top of the nipple cap. The nozzle outlet communicates with the nipple outlet, and a primary atomization structure is provided between the nozzle outlet and the nipple outlet.

[0005] Based on the above scheme, the primary atomizing structure is an atomizing guide channel, which is located inside the nipple cap. The atomizing guide channel is radial and its width decreases along the direction close to the nipple outlet.

[0006] Based on the above scheme, a two-stage atomization structure is provided on the upper part of the nipple cap. The two-stage atomization structure includes a mist point shell. Inside the mist point shell, a filter cotton, a primary atomizing plate, and a secondary atomizing plate are arranged sequentially from bottom to top. The primary atomizing plate and the secondary atomizing plate are respectively provided with primary atomizing holes and secondary atomizing holes. The primary atomizing holes and the secondary atomizing holes are arranged in an overlapping manner, and in the overlapping state, the area of ​​any through hole is smaller than the area of ​​the primary atomizing hole or the secondary atomizing hole.

[0007] Based on the above scheme, the aperture of the primary atomizing hole and the secondary atomizing hole is 0.05mm.

[0008] Preferably, there are multiple primary atomizing holes arranged in a honeycomb pattern in the middle of the primary atomizing plate, and the diameter of the inscribed circle of the multiple primary atomizing holes is the same as the diameter of the secondary atomizing plate. There are multiple secondary atomizing holes arranged in a regular hexagonal honeycomb pattern in the middle of the secondary atomizing plate.

[0009] Based on the above scheme, the through holes in the overlapping state of the primary atomizing holes and the secondary atomizing holes are arranged in two layers of rings. The outer ring through holes are evenly distributed circumferentially along the central axis of the nipple outlet, and have the same shape and area; the inner ring through holes are evenly distributed circumferentially along the central axis of the nipple outlet, and have the same shape and area; the sum of the areas of the outer ring through holes is greater than the sum of the areas of the inner ring through holes.

[0010] Preferably, the nozzle core rod includes a guide column, a sleeve, and a guide sleeve that are fixedly connected from top to bottom. The guide sleeve and the sleeve are fitted onto the outside of the mounting core rod. The guide channel includes a core rod guide groove, a core rod liquid outlet, and a guide groove. The core rod guide groove is arranged on the inside of the sleeve in a direction parallel to the axis of the nozzle core rod. The core rod liquid outlet is arranged between the sleeve and the side wall of the guide column. The guide groove is arranged on the outside of the guide sleeve in a direction parallel to the axis of the nozzle core rod.

[0011] Based on the above scheme, a nozzle mounting base is fixedly installed on the upper surface of the movable cover. The nozzle mounting base is annular and coaxially arranged with the mounting core rod. A nozzle seat buckle is provided on the side of the nozzle mounting base, and the lower surface of the nozzle seat buckle is a stepped surface. The lower part of the nozzle is sleeved on the outside of the nozzle mounting base, and a nozzle buckle is provided on the inner side of the lower part of the nozzle. The upper surface of the nozzle buckle is a stepped surface, and the upper surface of the nozzle buckle is engaged with the lower surface of the nozzle seat buckle. In the engaged state, the movable cover, the nozzle core rod, and the nozzle are axially fixed. A nipple slot is provided on the outer surface of the nozzle, and a nipple protrusion buckle is provided on the inner side of the nipple cap. The nipple protrusion buckle is engaged in the nipple slot.

[0012] Preferably, the nipple cap is made of thermoplastic elastomer material.

[0013] Preferably, the inner wall of the fixing seat is provided with a line sealing buckle adapted to the Φ25.4 aluminum can.

[0014] The beneficial effects of this invention are as follows:

[0015] 1. The spray mode and atomization mode of the nozzle can be switched by installing and removing the nipple cap. One nozzle can realize the integrated operation of spray rinsing and atomization, which is simple and convenient to use;

[0016] 2. The two-stage atomization structure can effectively reduce the diameter of atomized particles to 5-15μm, overcoming the problem of excessively large atomized particles caused by manufacturing precision limitations in existing products. This ensures that atomized particles can smoothly enter the lower respiratory tract, improving the treatment effect on lower respiratory tract lesions.

[0017] 3. The atomizing structure is located inside the nozzle, which, compared to existing products with external atomizing points, prevents the atomizing head from falling off during use, ensuring a safe and reliable structure.

[0018] 4. The nipple cap is made of soft rubber, and after the nipple cap is installed, the atomized particles are fine and gentle, and the atomization flow rate is moderate, which significantly improves the infant's acceptance of the nasal irrigator. Attached Figure Description

[0044] Example 1

[0045] like Figure 1 and Figure 2 As shown, a multi-purpose nasal irrigator nozzle includes a nozzle base, a nozzle core rod, a nozzle, and a nipple cap 4.

[0046] like Figures 3 to 5 As shown, the nozzle holder includes a fixed base 11 and a movable cover 13 that rotate relative to each other. Specifically, one side of the top surface of the movable cover 13 is elastically connected to the fixed base 11, and the remaining part of the top surface of the movable cover 13 is inclined above the fixed base 11. Thus, the movable cover 13 can be moved relative to the fixed base 11 by pressing the protruding part of the movable cover 13 relative to the fixed base 11. For easy identification, the highest point of the protruding part is defined as the movable end of the movable cover 13. A pressing mark 14 is provided on the top surface of the movable end. The pressing mark 14 can be a flat pattern or a protruding shape, making it easy for the user to identify the pressing position and press it with their thumb. Multiple reset hooks are fixedly connected to the outer edge of the bottom surface of the movable cover 13. The reset hooks are L-shaped. In the natural state of the movable cover 13, the bent part of the reset hook is hooked onto the fixed base 11, thereby limiting the position of the movable cover 13. The fixing seat 11 is installed on the upper end of the aluminum tube of the nasal irrigator. The inner wall of the fixing seat 11 is provided with a line-sealing buckle 12 that is compatible with the Φ25.4 aluminum can. The fixing seat 11 can be installed on the valve port with the φ25.4 aluminum can in one go by a stamping device, ensuring that the fixing seat 11 cannot be removed from the aluminum can by hand. The movable cover 13 is provided with a spray bar 15 facing the fixing seat 11. The movable cover 13 is provided with a spray bar outlet 16, and the spray bar outlet 16 is connected to the inner cavity of the spray bar 15.

[0047] A mounting core rod 19 is fixedly installed on the upper surface of the movable cover 13, and a nozzle mounting seat 17 is also fixedly installed on the upper surface of the movable cover 13. The nozzle mounting seat 17 is annular and coaxially arranged with the mounting core rod 19. The nozzle core rod is sleeved on the outside of the mounting core rod 19 and the inside of the nozzle mounting seat 17, and the nozzle is sleeved on the outside of the nozzle core rod. Specifically, as shown... Figure 2 , Figure 3 , Figure 10 and Figure 11As shown, a nozzle mounting base 17 has a nozzle seat buckle 18 on its side, and the lower surface of the nozzle seat buckle 18 is a stepped surface; the lower part of the nozzle is sleeved on the outside of the nozzle mounting base 17, and a nozzle buckle 32 is provided on the inner side of the lower part of the nozzle. The upper surface of the nozzle buckle 32 is a stepped surface, and the upper surface of the nozzle buckle 32 is engaged with the lower surface of the nozzle seat buckle 18. In the engaged state, the movable cover 13, the nozzle core rod and the nozzle are axially fixed.

[0048] A nozzle outlet 35 is provided at the top of the nozzle, and a flow guide channel is provided on the nozzle core rod to connect the nozzle outlet 16 with the nozzle outlet 35. Specifically, as shown... Figures 6 to 8 As shown, the nozzle core rod includes a guide column, a sleeve 22, and a guide sleeve 21, which are fixedly connected from top to bottom. The guide sleeve 21 and the sleeve 22 are sleeved on the outside of the mounting core rod 19. The guide channel includes a core rod guide groove 23, a core rod liquid outlet 24, and a guide groove 25. The core rod guide groove 23 is arranged inside the sleeve 22 in a direction parallel to the axis of the nozzle core rod. The core rod liquid outlet 24 is arranged between the sleeve 22 and the side wall of the guide column. The guide groove 25 is arranged outside the guide sleeve in a direction parallel to the axis of the nozzle core rod.

[0049] The nipple cap 4 is detachably fitted onto the upper outer part of the nozzle, such as... Figures 12 to 14 As shown, a nipple cap 4 has a nipple outlet 43 at its top, and a nozzle outlet 35 communicates with the nipple outlet 43. A primary atomizing structure is provided between the nozzle outlet 35 and the nipple outlet 43. The primary atomizing structure is an atomizing guide channel 42, which is located inside the nipple cap 4. This channel can be located inside the top of the nipple cap 4, or inside the upper part and top of the nipple cap 4. The atomizing guide channel 42 is radial, and its width decreases towards the nipple outlet 43, causing the liquid to flow through the atomizing guide channel 42 and form a mist, thus achieving a spray state. Preferably, as shown... Figure 9 and Figure 13 As shown, a nipple slot 33 is provided on the outer surface of the nozzle, and a nipple protrusion buckle 41 is provided on the inner side of the nipple cap 4. The nipple protrusion buckle 41 is engaged in the nipple slot 33 to limit the circumferential and axial position of the nipple cap 4 relative to the nozzle 3. The nipple cap 4 is made of thermoplastic elastomer material to improve comfort when in contact with the nasal cavity.

[0050] When using in spray mode, remove the nipple cap 4, hold the nasal irrigator canister with one hand, and press the movable cover 13 downwards from the press mark 14 with your thumb. The spray bar 15 drives the male valve stem of the irrigator downwards, causing the liquid in the irrigator canister to spray out. The liquid passes sequentially through the spray bar 15, the spray bar outlet 16, the core rod guide groove 23, the core rod outlet 24, and the guide groove 25, before being sprayed out from the nozzle outlet 35 in the form of a liquid column, achieving a columnar spray rinsing state. When using in atomization mode, install the nipple cap 4. Based on the atomization spray rinsing action, the liquid passes through the atomization guide groove 42 of the nipple cap 4, achieving an atomization effect.

[0051] Example 2

[0052] The difference between this embodiment and Embodiment 1 is that the upper part of the nipple cap 4 is provided with a two-stage atomization structure, such as... Figures 15 to 18 As shown, the secondary atomization structure includes a mist dot shell 51. Inside the mist dot shell 51, from bottom to top, are arranged a filter cotton 52, a primary atomizing plate 53, and a secondary atomizing plate 55. The primary atomizing plate 53 and the secondary atomizing plate 55 are respectively provided with primary atomizing holes 54 and secondary atomizing holes 56. The filter cotton 52 filters the liquid passing through the atomizing plates to prevent clogging. Figure 19 As shown, the primary atomizing hole 54 and the secondary atomizing hole 56 are arranged in an overlapping manner, and the area of ​​any through hole in the overlapping state is smaller than the area of ​​the primary atomizing hole 54 or the secondary atomizing hole 56, thereby further breaking up the atomized droplets and effectively reducing the droplet diameter.

[0053] Since the current limit for single-hole diameter injection molding or machining is 0.05mm, the diameters of the primary atomizing hole 54 and the secondary atomizing hole 56 are 0.05mm. Furthermore, by stacking multiple layers of atomizing holes with a diameter of 0.05mm, even smaller atomized particles can be obtained. Based on long-term production experience and filling process requirements, a maximum filling pressure of 0.9MPa was selected as the preset condition for calculation and simulation experiments. The experimental results show that infinite stacking does not achieve the smallest atomized particles. When three layers of atomizing sheets are stacked, the atomizing hole diameter becomes too small, and the internal solution rolls out from the atomizing holes in the form of droplets. Therefore, only two layers of atomizing sheets with a diameter of 0.05mm can be stacked.

[0054] like Figure 17 and Figure 18 As shown, there are multiple primary atomizing holes 54 arranged in a honeycomb pattern in the middle of the primary atomizing plate 53. The diameter of the inscribed circle of each primary atomizing hole 54 is the same as the diameter of the secondary atomizing plate 55, so that the primary atomizing holes 54 cover the area of ​​the secondary atomizing plate 55 as much as possible, and the droplets passing through the primary atomizing plate 53 are fully torn apart by the multiple primary atomizing holes 54. There are multiple secondary atomizing holes 56 arranged in a regular hexagonal honeycomb pattern in the middle of the secondary atomizing plate 55.

[0055] like Figure 20 and Figure 21 As shown, the through holes in the overlapping state of the primary atomizing hole 54 and the secondary atomizing hole 56 are arranged in two layers of rings. The outer ring of through holes is evenly distributed circumferentially along the central axis of the nipple outlet 43, and has the same shape and area. The inner ring of through holes is also evenly distributed circumferentially along the central axis of the nipple outlet 43, and has the same shape and area. The total area of ​​the through holes is equal in both arrangements. The difference lies in... Figure 20 The sum of the areas of the outer and middle ring through holes is greater than the sum of the areas of the inner ring through holes. Figure 21 The sum of the areas of the outer and inner ring through holes is smaller than the sum of the areas of the inner ring through holes. Because, under constant pressure, the pressure is concentrated along the central axis within the diffusion angle, while the pressure is relatively weaker at the edge of the diffusion angle, therefore... Figure 21 The six relatively larger through-holes in the inner ring of the atomization device exhibit a significant atomization effect, while the twelve relatively smaller through-holes in the outer ring, due to relative pressure, show less noticeable atomization and a more concentrated atomization diffusion angle. In comparison, Figure 20 The inner ring of the device features 12 extremely small mist droplets, while the outer ring has 6 relatively larger mist droplets, resulting in better atomization. Because the pressure is constant, the pressure is concentrated along the central axis within the diffusion angle, while the pressure is relatively weaker at the edges. The outer ring has 6 relatively larger mist droplets precisely at these weaker pressure areas, allowing for a relatively ideal atomization effect in that region. The atomized particles are fine and gentle, with a diameter of 5-15μm. The relatively large diffusion angle can cover the mouth and nose, and the atomization flow rate is 0.89-1.0ml / min, meeting the atomization flow rate requirements of commercially available active atomizing products. Figure 20 The best atomizing effect is achieved by stacking the atomizing plates in the middle.

[0056] The present invention has been described above by way of example, but the present invention is not limited to the specific embodiments described above. Any modifications or variations made based on the present invention shall fall within the scope of protection claimed by the present invention.
