Abstract
Description
Technical Field
[0001] This utility model relates to the technical field of nasal cavity cleaning products, and in particular to a nasal irrigator. Background Technology
[0002] Nasal irrigation is widely used as an adjunct treatment for upper respiratory tract diseases such as allergic rhinitis and sinusitis. Its core principle is to flush the nasal cavity with saline solution to remove secretions, allergens, and pathogens. However, in existing nasal irrigators, the cap is directly connected to the dispensing head, and the connecting tube between the cap and the dispensing head is relatively short. This results in a short flow path for the irrigation solution, and the constant inner diameter of the connecting tube can easily lead to unstable flow. For example, when the pressure on the bottle is low or the liquid flow is insufficient, the flow rate may drop sharply, failing to effectively flush the deep nasal passages and affecting the irrigation effect.
[0003] This utility model was proposed in response to the shortcomings of the existing technology. Utility Model Content
[0004] This invention addresses the problem mentioned above in existing nasal irrigators where the connecting tube between the cap and the dispensing head is too short, resulting in a short flow path for the rinsing fluid. Furthermore, the constant inner diameter of the connecting tube can easily lead to unstable flow of the rinsing fluid, affecting the rinsing effect. This invention proposes a new nasal irrigator.
[0005] The technical solution adopted by this utility model to solve its technical problem is: A nasal irrigator includes a bottle body, a cap covering the bottle body, an air inlet channel and a liquid outlet channel disposed between the bottle body and the cap body, the bottle body having a liquid storage chamber, the air inlet channel and the liquid outlet channel communicating with the liquid storage chamber, and a first one-way valve and a second one-way valve respectively provided in the air inlet channel and the liquid outlet channel; The outer side of the cover is provided with a liquid outlet pipe, and the liquid outlet pipe is provided with a first cavity communicating with the liquid outlet channel, and the inner diameter of the first cavity gradually decreases along the liquid outlet direction.
[0006] As described above, in a nasal irrigator, the liquid outlet tube extends outward from the top surface of the cover, and the bottom of the liquid outlet tube is provided with a first extension extending into the liquid storage cavity. The liquid outlet channel passes through the first extension. The nasal irrigator also includes a conduit disposed in the liquid storage cavity. The conduit is connected to the first extension through a second one-way valve, and the liquid outlet channel extends into the conduit.
[0007] The nasal irrigator described above further includes a dispensing head connected to the dispensing tube. The end of the dispensing tube away from the cover is provided with a second extension and a limiting step located outside the second extension. The second extension and the dispensing head are respectively provided with a second cavity and a through hole communicating with the dispensing channel. The dispensing head is sleeved on the second extension and abuts against the limiting step. The inner diameter of the second cavity is smaller than the inner diameter of the first cavity.
[0008] In the nasal irrigator described above, at least one protrusion is provided between the second extension and the liquid outlet head.
[0009] As described above, the nasal irrigator has an inclined outer wall on the outside of the dispensing head, and the outer diameter of the inclined outer wall gradually decreases along the dispensing direction.
[0010] As described above, a nasal irrigator has a connector on the outside of the bottle body, the connector having a first connecting portion, and a cap having a second connecting portion corresponding to the first connecting portion. The cap and the bottle body are detachably connected through the first connecting portion and the second connecting portion. A limiting structure is provided between the first connecting portion and the second connecting portion to restrict the relative movement between the cap and the bottle body along the liquid dispensing direction.
[0011] As described above, in a nasal irrigator, the bottle body and the connector are integrally formed, and the hardness of the connector is greater than that of the bottle body.
[0012] As described above, in a nasal irrigator, there is a predetermined angle between the bottom of the bottle and the liquid outlet tube.
[0013] In the nasal irrigator described above, the preset included angle is 15° to 35°.
[0014] As described above, the nasal irrigator further includes a third extension extending toward the liquid storage chamber, an air inlet channel passing through the third extension, and a first one-way valve connected to the third extension.
[0015] Compared with the prior art, the beneficial effects of this utility model are: 1. This utility model provides a nasal irrigator, including a bottle body, a cap body covering the bottle body, an air inlet channel and a liquid outlet channel disposed between the bottle body and the cap body. The bottle body has a liquid storage chamber, and the air inlet channel and the liquid outlet channel communicate with the liquid storage chamber. A first one-way valve and a second one-way valve are respectively provided in the air inlet channel and the liquid outlet channel. The first one-way valve is used to guide gas unidirectionally from the outside to the liquid storage chamber, and the second one-way valve is used to guide liquid unidirectionally from the liquid storage chamber to the outside. A liquid outlet pipe is provided on the outside of the cap body, and the liquid outlet pipe has a first cavity communicating with the liquid outlet channel, with the inner diameter of the first cavity gradually decreasing along the liquid outlet direction. The user can manually squeeze the bottle body, closing the first one-way valve to restrict air intake. The second one-way valve opens to allow the flushing fluid in the reservoir to flow outwards along the outlet channel and through the second one-way valve to rinse the nasal cavity. When the user releases the pressure on the bottle, the second one-way valve closes to limit the flow, while the first one-way valve opens, allowing outside air to be guided unidirectionally into the reservoir through the air inlet channel via the first one-way valve. This restores the pressure in the reservoir, preparing it for the next squeeze of the bottle and the output of flushing fluid, thus achieving continuous nasal rinsing. When the user releases the pressure on the bottle, the residual flushing fluid in the outlet tube flows back due to gravity. At this time, the second one-way valve closes to limit the backflow of flushing fluid in the outlet tube, preventing contamination of the flushing fluid in the reservoir.
[0016] 2. Since the dispensing head of a nasal irrigator is generally placed against the nostril and not inserted into the nasal cavity, the outlet of the dispensing head is far from the depth of the nasal cavity. If the flushing pressure of the rinsing fluid is low, the water flow is easily blocked by the folds of the nasal turbinates, making it difficult to reach the sinus openings and posterior nasal cavity, thus affecting the flushing effect. Therefore, in this embodiment, an extended dispensing tube is provided on the outside of the cover, and the inner diameter of the first tube gradually decreases along the dispensing direction of the dispensing channel, which helps to increase the flushing pressure of the rinsing fluid, allowing the rinsing fluid to penetrate deep into the nasal cavity, thereby improving the flushing effect.
[0017] The present invention will be further described below with reference to the accompanying drawings and specific embodiments. Attached Figure Description

The described embodiments are merely some, not all, of the embodiments of this utility model. All other embodiments obtained by those skilled in the art based on the embodiments of this utility model without inventive effort are within the scope of protection of this utility model.
[0020] It should be noted that all directional indicators (such as up, down, left, right, front, back, etc.) in this utility model embodiment are only used to explain the relative positional relationship and movement of each component in a certain specific posture (as shown in the figure). If the specific posture changes, the directional indicator will also change accordingly.
[0021] Furthermore, the use of terms such as "first" and "second" in this utility model is for descriptive purposes only and should not be construed as indicating or implying their relative importance or implicitly specifying the number of technical features indicated. Therefore, a feature defined as "first" or "second" may explicitly or implicitly include at least one of that feature. Additionally, the technical solutions of the various embodiments can be combined with each other, but only on the basis of being achievable by those skilled in the art. When the combination of technical solutions is contradictory or impossible to implement, such a combination of technical solutions should be considered non-existent and not within the scope of protection claimed by this utility model.
[0022] like Figure 1As shown in Figure 6, this utility model provides a nasal irrigator, including a bottle body 1, a cap 2 covering the bottle body 1, an air inlet channel 3 and a liquid outlet channel 4 disposed between the bottle body 1 and the cap 2. The bottle body 1 has a liquid storage chamber 11. The air inlet channel 3 and the liquid outlet channel 4 are connected to the liquid storage chamber 11. The air inlet channel 3 and the liquid outlet channel 4 are respectively provided with a first one-way valve 5 and a second one-way valve 6. The first one-way valve 5 is used to guide gas from the outside to the liquid storage chamber 11 in one direction, and the second one-way valve 6 is used to guide liquid from the liquid storage chamber 11 to the outside in one direction. The outer side of the cap 2 is provided with a liquid outlet pipe 21, and the liquid outlet pipe 21 has a first cavity 211 communicating with the liquid outlet channel 4, and the inner diameter of the first cavity 211 gradually decreases along the liquid outlet direction; in this embodiment, the bottle body 1 can be set as a flexible bottle body 1, and the user can manually squeeze the bottle body 1, the first one-way valve 5 closes to restrict air intake, and at the same time the second one-way valve 6 opens to allow the flushing liquid in the liquid storage chamber 11 to rush out to the outside along the liquid outlet channel 4 through the second one-way valve 6 to flush the nasal cavity; the first cavity 211 can be set as a conical cavity; when the user cancels the operation of the bottle body After squeezing 1, the second one-way valve 6 closes to limit the liquid output, while the first one-way valve 5 opens. The bottle 1, through the air inlet channel 3, guides external gas one-way through the first one-way valve 5 into the liquid storage chamber 11, restoring the pressure within the liquid storage chamber 11. This prepares the bottle 1 for the next squeezing and output of rinsing fluid, enabling continuous nasal rinsing. When the user releases the squeezing of the bottle 1, the residual rinsing fluid in the outlet tube 21 will flow back due to gravity. At this time, closing the second one-way valve 6 limits the backflow of rinsing fluid in the outlet tube 21, preventing the liquid from being stored in the reservoir. The rinsing fluid in the fluid chamber 11 is contaminated. In addition, since the nasal irrigator's outlet head 8 is generally placed against the nostril and is not usually inserted into the nasal cavity, the outlet of the outlet head 8 is far from the depth of the nasal cavity. If the rinsing pressure of the rinsing fluid is low, the water flow is easily blocked by the folds of the nasal turbinates and has difficulty reaching the sinus openings and posterior nasal cavity, thus affecting the rinsing effect. Therefore, in this embodiment, an extended outlet tube 21 is provided on the outside of the cover 2, and the inner diameter of the first tube 211 gradually decreases along the outlet direction of the outlet channel 4, which is beneficial to increase the rinsing pressure of the rinsing fluid, so that the rinsing fluid can penetrate into the depth of the nasal cavity, thereby improving the rinsing effect.
[0023] In this embodiment, the liquid storage chamber 11 can store flushing fluids such as physiological saline or medicinal solutions, and this utility model does not make any specific limitations.
[0024] Optionally, the first one-way valve 5 and the second one-way valve 6 may use the same or different valve bodies, such as movable air valves, duckbill valves, etc. This utility model does not make specific limitations, as long as the guiding directions of the first one-way valve 5 and the second one-way valve 6 are opposite.
[0025] In some alternative embodiments, the first one-way valve 5 and the second one-way valve 6 are duckbill valves. The duckbill valve is integrally molded from elastic material, has a simple structure, is lightweight, and has the characteristics of efficient sealing, low flow resistance, and strong adaptability. It is more suitable for manual nasal irrigators and has lower requirements for users, so it can be used by both adults and children.
[0026] As shown in Figures 3 and 5, the liquid outlet pipe 21 extends outward from the top surface of the cover 2. The bottom of the liquid outlet pipe 21 is provided with a first extension 22 extending into the liquid storage chamber 11. The liquid outlet channel 4 passes through the first extension 22. The nasal irrigator also includes a conduit 7 disposed in the liquid storage chamber 11. The conduit 7 is connected to the first extension 22 through the second one-way valve 6. The liquid outlet channel 4 extends into the conduit 7. In this embodiment, the first extension 22 is set as a sleeve. The second one-way valve 6 is connected to the inside of the first extension 22. The conduit 7 is connected to the inside of the second one-way valve 6. This helps to enhance the connection stability and sealing between the conduit 7, the second one-way valve 6 and the cover 2, and avoids leakage that would affect the rinsing effect.
[0027] like Figure 3 and Figure 5 As shown, the cover 2 is also provided with a third extension 24 extending toward the liquid storage chamber 11. The air inlet channel 3 passes through the third extension 24, and the first one-way valve 5 is connected to the third extension 24. In this embodiment, the third extension 24 is configured as a sleeve, the liquid inlet channel is located inside the third extension 24, and the first one-way valve 5 is connected to the outside of the third extension 24 to prevent the first one-way valve 5 from falling out of the air inlet channel 3 and out of the nasal irrigator when the bottle 1 is squeezed, thereby ensuring the normal use of the nasal irrigator.
[0028] In some alternative embodiments, the liquid outlet tube 21 and the cover 2 are integrally molded from hard plastics such as TPU and PP, which helps to enhance structural strength, further improve the connection and sealing of the cover 2, and reduce the number of accessories, thus reducing the difficulty of disassembling and assembling the nasal irrigator.
[0029] like Figure 2 and Figure 5As shown, the nasal irrigator also includes a dispensing head 8 connected to the dispensing tube 21. The end of the dispensing tube 21 away from the cover 2 is provided with a second extension 212 and a limiting step 213 located outside the second extension 212. The second extension 212 and the dispensing head 8 are respectively provided with a second cavity 2121 communicating with the dispensing channel 4 and a through hole 81. The through hole 81 communicates with the dispensing channel 4 and the outside. The dispensing head 8 is sleeved on the outside of the second extension 212 through the through hole 81 and abuts against the limiting step 213. The inner diameter of the second cavity 2121 is smaller than the inner diameter of the first cavity 211. In this embodiment, the dispensing channel 4 passes through the conduit 7, the dispensing tube 21, and the dispensing head. 8. Since the inner diameter of the first cavity 211 gradually decreases from the bottom of the outlet pipe 21 along the outlet direction, and the minimum inner diameter of the first cavity 211 is formed at the connection between the first cavity 211 and the second cavity 2121, the inner diameter of the second cavity 2121 can be set to a constant inner diameter or can be set to gradually decrease along the outlet direction. The maximum inner diameter of the second cavity 2121 is smaller than the minimum inner diameter of the first cavity 211, so as to further reduce the inner diameter of the outlet channel 4, thereby further enhancing the flushing pressure of the flushing fluid and improving the flushing effect. Alternatively, the inner diameter of the through hole 81 can be set to a constant inner diameter or can be set to gradually decrease along the outlet direction. This embodiment does not make specific limitations.
[0030] In other alternative embodiments, such as Figure 2 and Figure 6 As shown, at least one protrusion 2122 is provided between the second extension 212 and the liquid outlet head 8. In this embodiment, at least one protrusion 2122 is provided on the outer wall of the second extension 212, and the protrusion 2122 abuts against the inner wall of the through hole 81. Optionally, the protrusion 2122 can be configured as a convex ring extending circumferentially along the second extension 212, or other shaped protrusions, protrusions, etc., which are externally convex structures. This embodiment does not make specific limitations. The protrusion 2122 enhances the connection stability between the liquid outlet head 8 and the second extension 212, so as to prevent the liquid outlet head 8 from being separated from the liquid outlet tube 21 by the pressure inside the liquid storage chamber 11. Further optionally, the liquid outlet head 8 can be made of flexible materials such as medical silicone, so that the liquid outlet head 8 has an elastic pre-tightening force, so as to further enhance the connection stability and sealing between the liquid outlet head 8 and the liquid outlet tube 21, thereby improving the flushing effect.
[0031] In other alternative embodiments, such as Figure 6As shown, the liquid outlet head 8 has an inclined outer wall 82, and the outer diameter of the inclined outer wall 82 gradually decreases along the liquid outlet direction. In this embodiment, the outer wall of the liquid outlet head 8 can be configured as an umbrella-shaped, cone-shaped or other structures to ensure that the liquid outlet head 8 is used in contact with the nostril and to avoid the liquid outlet head 8 being inserted into the nasal cavity and damaging the user's nasal cavity.
[0032] Further optional, such as Figure 6 As shown, the liquid outlet head 8 is also provided with a concave wall 83 connected to the inclined outer wall 82. The concave wall 83 extends from the inclined outer wall 82 toward the cover body 2. The concave wall 83 and the inclined outer wall 82 form a relatively gentle connecting wall, which is convenient for users to disassemble and replace the liquid outlet head 8.
[0033] like Figure 2 , 3 As shown in Figure 6, a connector 12 is provided on the outer side of the bottle body 1. The connector 12 has a first connecting part 121, and the cap 2 has a second connecting part 23 corresponding to the first connecting part 121. The cap 2 and the bottle body 1 are detachably connected through the first connecting part 121 and the second connecting part 23. A limiting structure is provided between the first connecting part 121 and the second connecting part 23 to restrict the relative movement between the cap 2 and the bottle body 1 along the liquid dispensing direction. In the example, the first connecting part 121 and the second connecting part 23 can be configured as corresponding threaded connection structures, L-shaped groove screw-lock structures, etc., so that after the first connecting part 121 and the second connecting part 23 are connected, a limiting structure is formed that can restrict the cap 2 from moving relative to the bottle 1 along the liquid outlet direction; when the user releases the squeezing force on the bottle 1, air enters through the air inlet channel 3, and the pressure in the liquid storage chamber 11 rises. At this time, the limiting structure can restrict the cap 2 from detaching from the bottle 1 along the liquid outlet direction to ensure the continuous use of the nasal irrigator.
[0034] To enhance the connection stability of the bottle body 1, in some alternative embodiments, the bottle body 1 and the connector 12 are integrally molded, and the hardness of the connector 12 is greater than that of the bottle body 1. In this embodiment, the bottle body 1 and the connector 12 can be integrally molded using an overmolding process. The bottle body 1 can be made of soft rubber materials such as medical silicone, and the connector 12 can be made of hard rubber materials such as TPU. By providing the connector 12 on the outside of the bottle body 1, it is beneficial to improve the structural strength of the bottle body 1, thereby enhancing the connection stability of the bottle body 1; and it is also beneficial to simplify the production steps of the bottle body 1, reduce the number of accessories of the nasal irrigator, thereby further simplifying the structure of the nasal irrigator, reducing the production cost of the nasal irrigator, and improving the production efficiency of the nasal irrigator.
[0035] To improve the convenience of using the nasal irrigator, in some alternative embodiments, such as Figure 4 As shown, there is a preset angle S between the bottom of the bottle body 1 and the liquid outlet tube 21. Further, the preset angle S is 15° to 35°. In practical applications, when users use the nasal irrigator to rinse their nasal cavity, they usually tilt their head forward at a certain angle, such as bending over in front of a washbasin. At this time, the liquid outlet tube 21 naturally fits against the face, without the need to deliberately tilt the head back or down, thus avoiding tension in the user's neck muscles. Moreover, this embodiment uses the concept of ergonomics to set the preset angle S, which can keep the user's wrist in a neutral position when the user holds the nasal irrigator, which helps to reduce hand fatigue during long-term operation, thereby enhancing the user's comfort and convenience in using the nasal irrigator and optimizing the user experience.
[0036] In some alternative embodiments, the preset included angle S is 15° to 30°.
[0037] In some alternative embodiments, the preset included angle S is 25° to 35°.
[0038] To further enhance the convenience of using the nasal irrigator, in some alternative embodiments, such as Figure 1 and Figure 4 As shown, the outer wall of the bottle body 1 is also provided with a capacity mark, which includes at least a maximum capacity mark 91. Since the bottle body 1 is made of flexible materials such as medical silicone, the user can see the liquid level through the bottle body 1 when filling the bottle body 1. By setting the maximum capacity mark 91, the excessive filling of the flushing fluid and leakage can be avoided.
[0039] In other alternative embodiments, such as Figure 1 and Figure 4 As shown, the capacity markings also include a minimum capacity marking 92. The maximum capacity marking 91 and the minimum capacity marking 92 are spaced apart along the height of the bottle body 1. The minimum capacity marking 92 is used to remind the user to replenish the flushing fluid in a timely manner.
[0040] The above examples are merely illustrative of the technical content of this utility model to facilitate reader understanding, but do not imply that the implementation of this utility model is limited to these embodiments. Any technical extensions or re-creations made based on this utility model are protected by this utility model. The scope of protection of this utility model is defined by the claims.
