[0001] This utility model relates to the field of medical equipment technology, and in particular to a nasal irrigator and nasal irrigation device. Background Technology
[0002] Existing nasal spray irrigators rely on a built-in miniature air pump to generate a continuous and stable airflow.

However, the miniature air pump in these irrigators is limited by a stable power supply and cannot operate in environments with power outages or no power, thus restricting the user's scope of use. Furthermore, because they contain easily damaged components such as motors, frequent use can lead to wear and tear or malfunction, thereby shortening the lifespan of the irrigator.

The snap-fit engagement portion engages with the snap-fit portion to fix the air inlet pipe to the support plate and connect it to the air guide pipe through the communication port.
[0018] In one embodiment, the support further includes:
[0019] A partition is provided on the side of the support plate facing the liquid chamber, dividing the liquid chamber into a raw liquid chamber and a waste liquid chamber; the atomizing head has an atomizing chamber and an atomizing port and a nasal irrigation port communicating with the atomizing chamber; the raw liquid chamber is communicating with the atomizing port and is used to hold cleaning fluid; the air guide pipe is provided in the raw liquid chamber; the waste liquid chamber is communicating with the atomizing chamber and is used to collect the cleaning fluid after cleaning through the nasal irrigation port.

[0038] Existing nasal spray irrigators rely on a built-in miniature air pump to generate a continuous and stable airflow. This airflow, when passing through the nozzle, causes the saline solution to form a fine mist, which is then sprayed directly into the nasal cavity for cleaning. However, the miniature air pump in these irrigators is limited by a stable power supply and cannot operate in environments with power outages or no power, thus restricting the user's scope of use. Furthermore, because they contain easily damaged components such as motors, frequent use can lead to wear and tear or malfunction, thereby shortening the lifespan of the irrigator.
[0039] To solve the above problems, this utility model proposes a nasal irrigator 100.
[0040] Please see Figures 1 to 4 In one embodiment of this utility model, the nasal irrigator 100 includes:
[0041] The housing 1 is provided with a liquid chamber 1011, a mounting chamber 1012 and an air inlet 102 communicating with the mounting chamber 1012;
[0042] The air intake assembly 2 includes an air intake pipe 21, an air duct 22, and an exhaust pipe 23 disposed in the mounting cavity 1012. One end of the air intake pipe 21 is connected to the air duct 22 and the exhaust pipe 23, and the other end of the air intake pipe 21 is disposed at the air inlet 102 and forms an exhaust gap 103 with the air inlet 102. The air duct 22 is connected to the liquid cavity 1011.
[0043] Atomizing head 3 is located on housing 1 and is connected to liquid chamber 1011 and air duct 22;
[0044] The trigger 4, located on the housing 1, is used to cut off the connection between the exhaust gap 103 and the exhaust pipe 23 when triggered, so that when the gas from the gas source is transmitted to the air duct 22, the cleaning liquid in the liquid chamber 1011 can be carried out and mixed with the gas to atomize into water vapor and then sprayed out through the atomizing head 3.
[0045] In this embodiment, the housing 1 is the main outer shell of the nasal irrigator 100, which can be a cylindrical structure made of lightweight and durable materials (such as plastic). The liquid chamber 1011 can be located at the top or side of the housing 1 and is used to store the cleaning fluid, such as saline solution. When the liquid chamber 1011 is located at the top of the housing 1, the mounting chamber 1012 can be located at the bottom of the housing 1; or, when the liquid chamber 1011 is located at the first side of the housing 1, the mounting chamber 1012 can be located at the second side of the housing 1, wherein the second side is opposite to the first side. The mounting chamber 1012 is used to accommodate the air intake assembly 2. The compartments of the housing 1 can achieve physical isolation between the cleaning fluid and the air intake assembly 2, preventing the cleaning fluid from leaking or contaminating the air intake assembly 2. The air inlet 102 is opened on the cavity wall of the housing 1 corresponding to the mounting chamber 1012 and communicates with the mounting chamber 1012, serving as the access point for an external air source. The external air source can be a manually squeezed airbag, or it can be a breathing airflow, etc., without any special restrictions here.
[0046] The air intake assembly 2 includes an air intake pipe 21, a duct 22, and an exhaust pipe 23 located in the mounting cavity 1012. The air intake pipe 21 can be a hollow tubular structure. One end of the air intake pipe 21 can be connected to and communicate with the duct 22 and the exhaust pipe 23 by means of threads, snaps, or integral molding. The other end extends to the air inlet 102, forming an annular or linear exhaust gap 103 between the air intake pipe 21 and the air inlet 102. The duct 22 connects the air intake pipe 21 and the liquid cavity 1011. The internal channel can be set as a slender or spiral structure to enhance the airflow's ability to carry the original liquid. The exhaust pipe 23 is located in the mounting cavity 1012 and communicates with the air intake pipe 21. It is used to discharge excess gas in the non-triggered state and maintain the pressure balance of the nasal irrigator 100. Through the linkage design of the exhaust gap 103 and the exhaust pipe 23, the airflow can be switched between the liquid intake mode and the exhaust mode without relying on motor drive.
[0047] The atomizing head 3 can be a conical or trumpet-shaped nozzle. One end of the atomizing head 3 is installed on the housing 1 and connected to the air duct 22 and the liquid chamber 1011. The other end of the atomizing head 3 can be provided with a nasal irrigation port 303. The inner wall of the nasal irrigation port 303 can be provided with a serrated or vortex structure to further atomize the liquid after the gas and cleaning fluid are mixed into fine particles, thereby improving the atomization effect on the nasal cavity.
[0048] The trigger 4 can be a button, lever, or slider, used to block the passage between the exhaust gap 103 and the exhaust pipe 23 when triggered by the user, allowing airflow to enter the liquid chamber 1011 through the air guide 22. Air pressure then carries the cleaning fluid out and mixes it into atomized liquid, achieving "manual control" instead of motor drive. Since the trigger 4 is a purely mechanical structure, without easily damaged motors or bearings, the risk of wear is reduced, improving the durability of the nasal irrigator 100. Furthermore, the user can instantly control the spray start and stop through the physical operation of the trigger 4, making operation simple and intuitive.
[0049] In practical applications, when a user needs the nasal irrigator 100, they can press the trigger 4. The trigger 4 is activated, cutting off the connection between the exhaust gap 103 and the exhaust pipe 23. This allows external air to directly enter through the air duct 22, carrying out the cleaning fluid in the liquid chamber 1011, mixing it with the gas, and atomizing it into water vapor. Finally, this vapor is sprayed out through the atomizing head 3 to clean the nasal cavity. After cleaning, the air supply stops, the trigger 4 is no longer triggered, and the exhaust gap 103 and exhaust pipe 23 re-establish a connection. The gas in the air duct 22 and the air inlet pipe 21 can be discharged to the external environment through the exhaust gap 103 and the air inlet 102, respectively. Because the nasal irrigator 100 of this invention does not use a miniature air pump, it is not limited by power supply and can operate in environments without power, greatly expanding the user's usage scenarios. Furthermore, by reducing the use of easily damaged parts such as motors and bearings, even with frequent use, the risk of wear or failure is reduced, effectively extending the service life of the nasal irrigator 100.
[0050] Please see Figures 1 to 4 In one embodiment of this utility model, the liquid chamber 1011 and the mounting chamber 1012 are arranged along the height direction of the housing 1; the air inlet pipe 21 is provided in the mounting chamber 1012, one end of the air inlet pipe 21 extends along the height direction of the housing 1 and communicates with the air guide pipe 22 and the exhaust pipe 23, the other end of the air inlet pipe 21 extends along the length direction of the housing 1 to the air inlet 102, the air guide pipe 22 is provided in the liquid chamber 1011 and extends along the height direction of the housing 1, and the exhaust pipe 23 extends along the length direction of the housing 1.
[0051] In this embodiment, the liquid chamber 1011 and the mounting chamber 1012 are arranged sequentially along the height of the housing 1, specifically, the liquid chamber 1011 is located at the top of the housing 1, and the mounting chamber 1012 is located at the bottom of the housing 1. This layout maximizes the use of the vertical space of the housing 1, making the overall structure of the nasal irrigator 100 compact and easy for the user to operate by hand. Furthermore, since the liquid chamber 1011 is located above the mounting chamber 1012, the cleaning fluid can flow naturally to the air duct 22 by gravity, reducing reliance on additional power (such as an air pump), further simplifying the structure and improving energy efficiency.
[0052] One end of the intake pipe 21 extends upward from the mounting cavity 1012 and connects to the air duct 22, which is also located in the height direction of the housing 1, and to the exhaust pipe 23 located in the length direction of the housing 1. The other end of the intake pipe 21 extends along the length direction of the housing 1 to the air inlet 102 on the side of the housing 1, so as to facilitate access to an external air source.
[0053] The air duct 22 extends upward from the bottom of the liquid chamber 1011 to the top of the liquid chamber 1011, which can ensure that the airflow path is consistent with the direction of liquid gravity, so that the airflow can carry the cleaning liquid at the bottom of the liquid chamber 1011 more efficiently, improve the atomization efficiency, and the vertical path of the air duct 22 can prolong the contact time between air and liquid, promote the full mixing of airflow and liquid, and make the atomized particles more uniform.
[0054] One end of the exhaust pipe 23 is connected to and communicates with the air inlet pipe 21, and the other end extends to the cavity wall of the mounting cavity 1012. This configuration can quickly release excess air pressure in the non-triggered state, avoiding structural deformation or operational difficulties caused by overpressure of the nasal irrigator 100. Furthermore, the exhaust path of the exhaust pipe 23 is separated from the air guide path of the air guide pipe 22, which can reduce the risk of airflow backflow and ensure the reliability of airflow path switching when the trigger 4 is triggered.
[0055] In summary, this embodiment optimizes the internal space layout of the housing 1, thereby achieving efficient coordination between the air path and the liquid storage, and further improving the durability of the nasal irrigator 100.
[0056] Please see Figures 1 to 4 In one embodiment of this utility model, the housing 1 includes:
[0057] The shell body 11 has a cavity 101;
[0058] The bracket 12 is provided in the cavity 101 to divide the cavity 101 into a liquid cavity 1011 and an installation cavity 1012. The bracket 12 is provided with a communication port 104, and the air inlet pipe 21 is connected to the air duct 22 through the communication port 104.
[0059] In this embodiment, the shell body 11 serves as the main frame of the nasal irrigator 100 and can be made of plastic, silicone, or lightweight alloy, with an internal cavity 101. The bracket 12 can also be made of plastic, silicone, or lightweight alloy. The bracket 12 can be installed on the cavity 101 by snap-fit, threading, welding, or integral molding to divide the cavity 101 into a liquid cavity 1011 and an installation cavity 1012. The liquid cavity 1011 is used to store the cleaning fluid and install the air duct 22, while the installation cavity 1012 is used to install the air inlet pipe 21. To achieve communication between the air inlet pipe 21 and the air duct 22, the bracket 12 is provided with a communication port 104. The air inlet pipe 21 is connected to the air duct 22 via the communication port 104 of the bracket 12, allowing airflow to smoothly flow from the air inlet pipe 21 in the installation cavity 1012 into the air duct 22 in the liquid cavity 1011, thereby reducing energy loss and improving atomization efficiency. Optionally, a sealing ring may be embedded in the edge of the connection port 104 to reduce the possibility of air leakage or liquid seepage.
[0060] Please see Figures 1 to 4 In one embodiment of this utility model, the bracket 12 includes:
[0061] Support plate 121 is provided with a connecting port 104;
[0062] The flow guide 122 is located on the side of the support plate 121 facing the liquid chamber 1011. The flow guide 122 is positioned corresponding to the connection port 104. The outer periphery of the flow guide 122 is fitted with an air guide pipe 22. The flow guide 122 is connected to the air guide pipe 22 and is connected to the air inlet pipe 21 via the connection port 104.
[0063] In this embodiment, the support plate 121 is the core load-bearing component of the bracket 12. It can be a flat plate structure and is installed in the cavity 101 by means of snap-fit, thread, welding or integral molding. The support plate 121 has a connecting port 104, which is strictly aligned with the guide section 122 and the air inlet pipe 21 to ensure the precise guidance of the airflow path.
[0064] The guide section 122 can be a hollow cylinder or a cone shape, and is installed on the side of the support plate 121 facing the liquid chamber 1011 by means of snap-fit, thread, welding or integral molding, and is coaxially arranged with the connecting port 104. A guide tube 22 is spaced around the outer periphery of the guide section 122, one end of which is connected to the guide tube 22, and the other end is connected to the air inlet pipe 21 via the connecting port 104. This allows the airflow from the air inlet pipe 21 to be precisely guided to the guide tube 22, preventing airflow dispersion or backflow, and ensuring efficient air pressure transmission to the liquid chamber 1011. Furthermore, by providing the guide section 122, the airflow forms a specific flow pattern before entering the guide tube 22, which can more efficiently entrain the cleaning liquid at the bottom of the liquid chamber 1011, improving atomization efficiency.
[0065] Please see Figures 1 to 4 In one embodiment of the present invention, the diameter of the air duct 22 gradually decreases from the end closer to the air inlet pipe 21 toward the end farther away from the air inlet pipe 21.
[0066] In this embodiment, the diameter of the air duct 22 gradually decreases from the end near the air inlet pipe 21 to the end away from the air inlet pipe 21. Since the air duct 22 is fitted around the outer periphery of the guide section 122, it can be known that the diameter of the guide section 122 also gradually decreases from the end near the air inlet pipe 21 to the end away from the air inlet pipe 21. When the airflow passes through the guide section 122, the flow velocity increases as the diameter of the guide section 122 decreases. According to the continuity equation, the kinetic energy increases, forming a stronger negative pressure zone. This allows for more efficient entrainment of the cleaning fluid in the liquid chamber 1011 through the air duct 201. Furthermore, due to the concentration of kinetic energy of the high-speed airflow at the air duct 201, the cleaning fluid can be broken into finer atomized particles, improving the uniformity and comfort of nasal cleaning.
[0067] Please see Figures 1 to 4In one embodiment of the present invention, the air duct 22 has an air duct 201 that communicates with the liquid chamber 1011, and the flow guide 122 is provided with a flow guide 105 at the position corresponding to the air duct 201. The position of the flow guide 122 corresponding to the flow guide 105 is spaced apart from the air duct 22.
[0068] In this embodiment, the air guide 201 is located at the top of the air guide duct 22, away from the bottom of the liquid chamber 1011. This allows the airflow to directly act on the vicinity of the cleaning fluid surface, avoiding the intake of impurities or sediments that may be present at the bottom, thus improving the purity of the cleaning fluid. Furthermore, after the airflow enters the air guide duct 22 from the guide section 122, the air guide 201 at the top can utilize the pressure difference to more efficiently draw the cleaning fluid near the liquid surface into the airflow, reducing liquid residue. The air guide 201 and the guide port 105 are precisely aligned axially, ensuring the shortest and unobstructed airflow path between the air guide duct 22 and the guide section 122. This allows for controlled impact on the cleaning fluid surface, forming more stable atomized particles and improving the atomization effect. The shapes of the air guide 201 and the guide port 105 can be matched or mismatched. For example, the air guide 201 and / or the guide port 105 can be circular or elongated openings; no specific limitations are imposed here. At the positions of the guide section 122 and the guide duct 22 corresponding to the guide port 105, a certain gap is maintained between them to form an annular channel. After the airflow flows out of the guide port 105 of the guide section 122, it needs to enter the guide port 201 of the guide duct 22 through the gap, during which a vortex or accelerated flow is formed, thereby enhancing the entrainment capacity of the cleaning fluid in the liquid chamber 1011 and improving the atomization effect.
[0069] Please see Figures 1 to 4 In one embodiment of the present invention, the support plate 121 is provided with a snap-fit part 123 on the side corresponding to the position of the communication port 104 and facing the mounting cavity 1012. The end of the air inlet pipe 21 away from the air inlet 102 is provided with a snap-fit mating part 24. The snap-fit mating part 24 and the snap-fit part 123 snap-fit together to fix the air inlet pipe 21 to the support plate 121 and connect it to the air duct 22 through the communication port 104.
[0070] In this embodiment, the snap-fit portion 123 is located at the position corresponding to the communication port 104 on the support plate 121 and protrudes towards the mounting cavity 1012. The snap-fit portion 123 can be a snap-fit protrusion, a slot, or a hook, and the material can be the same as that of the support plate 121. The snap-fit mating portion 24 is located at the end of the air intake pipe 21 away from the air intake port 102, that is, the end closer to the support plate 121. The snap-fit mating portion 24 can be a flange snap-fit protrusion, a slot, or a hook, but it forms a complementary structure with the snap-fit portion 123. In this embodiment, the snap-fit part 24 is implemented using a slot, while the snap-fit part 123 is implemented using a buckle protrusion. The buckle protrusion engages with the slot to fix the air inlet pipe 21 to the support plate 121. The air inlet pipe 21 can be installed and removed without tools, improving the production efficiency of the nasal irrigator 100 and the user's maintenance convenience. After snap-fitting, the air inlet pipe 21 can be connected to the air duct 22 through the connecting port 104. The connection between the air inlet pipe 21 and the air duct 22 can be achieved without the use of a connecting pipe, improving the connection efficiency between the two. The airflow can also completely enter the air duct 22 through the connecting port 104, avoiding the decrease in atomization efficiency caused by gas leakage.
[0071] Please see Figures 1 to 4 In one embodiment of this utility model, the bracket 12 further includes:
[0072] A partition 124 is provided on the side of the support plate 121 facing the liquid chamber 1011. The partition 124 divides the liquid chamber 1011 into a raw liquid chamber 10111 and a waste liquid chamber 10112. The atomizing head 3 has an atomizing chamber 301 and an atomizing port 302 and a nasal irrigation port 303 connected to the atomizing chamber 301. The raw liquid chamber 10111 is connected to the atomizing port 302. The raw liquid chamber 10111 is used to hold the cleaning liquid. The air duct 22 is provided in the raw liquid chamber 10111. The waste liquid chamber 10112 is connected to the atomizing chamber 301. The waste liquid chamber 10112 is used to collect the cleaning liquid after cleaning through the nasal irrigation port 303.
[0073] In this embodiment, the partition 124 can be installed on the side of the support plate 121 facing the liquid chamber 1011 by means of snap-fit, thread, welding or integral molding, dividing the liquid chamber 1011 into a raw liquid chamber 10111 and a waste liquid chamber 10112. The raw liquid chamber 10111 and the waste liquid chamber 10112 are arranged opposite each other along the horizontal direction of the housing 1. The raw liquid chamber 10111 is used to store the cleaning fluid, and the waste liquid chamber 10112 is used to collect the cleaning fluid after cleaning. In this way, the unused cleaning fluid can be completely separated from the cleaning fluid after cleaning, avoiding the cleaning fluid after cleaning from contaminating the unused cleaning fluid and improving the hygiene of the nasal irrigator 100.
[0074] Note that the atomizing head 3 has an atomizing chamber 301, an atomizing port 302, and a nasal irrigation port 303, which are connected to the atomizing chamber 301. The atomizing port 302 is also connected to the original liquid storage tank 10111. The air duct 22 is located in the original liquid storage tank 10111. The airflow from its air duct 201 atomizes the cleaning solution through the atomizing port 302 and transmits it to the atomizing chamber 301. From the atomizing chamber 301, the solution is transmitted to the nasal irrigation port 303 and finally into the nasal cavity for cleaning. The nasal irrigation port 303 is also connected to the waste liquid storage tank 10112. The cleansing solution after cleaning flows back from the nasal cavity through the nasal irrigation port 303 and the atomizing chamber 301 to the waste liquid storage tank 10112, reducing the risk of facial contamination and improving user comfort.
[0075] Please see Figures 1 to 4 In one embodiment of this utility model, the nasal irrigator 100 further includes:
[0076] The elastic element 5 is disposed on the trigger 4 and located in the mounting cavity 1012. The elastic element 5 is disposed facing the exhaust pipe 23 and is used to deform when the trigger 4 is triggered to seal the exhaust pipe 23.
[0077] In this embodiment, the elastic element 5 is a silicone plug. The silicone plug is installed on the trigger 4 and located in the mounting cavity 1012, also facing the exhaust pipe 23. When the trigger 4 is pressed, the silicone plug deforms under force and completely covers the outlet of the exhaust pipe 23, forming an airtight seal, forcing the airflow to drive the cleaning fluid only through the air guide 22. The silicone plug can also automatically reset after the trigger 4 is released, opening the exhaust pipe 23 and restoring the nasal irrigator 100 to its ready-to-use state without additional operation. That is, by setting the silicone plug, the user only needs to press the trigger 4 to start the cleaning, and it automatically resets after release, simplifying the operation steps.
[0078] This utility model also proposes a nasal irrigation device, which includes an air source and a nasal irrigator 100. The specific structure of the nasal irrigator 100 is as described in the above embodiments. Since this nasal irrigation device adopts all the technical solutions of all the above embodiments, it has at least all the beneficial effects brought about by the technical solutions of the above embodiments, which will not be described in detail here.
[0079] The air source can be a manual air source, such as a squeeze-type airbag, or an electric air source, such as a miniature air pump; no specific restrictions are imposed here. In practical applications, when a user needs to use the nasal irrigator 100, they can press the trigger 4. The trigger 4 is activated, which cuts off the connection between the exhaust gap 103 and the exhaust pipe 23, allowing the gas output from the air source to directly enter through the air duct 22. This carries out the cleaning fluid in the liquid chamber 1011, mixes it with the gas, and atomizes it into water vapor. Finally, the vapor is sprayed out through the atomizing head 3 to clean the nasal cavity. After cleaning is completed, the air source stops supplying gas, the trigger 4 is no longer triggered, the exhaust gap 103 and the exhaust pipe 23 re-establish the connection, and the gas in the air duct 22 and the air inlet pipe 21 can be discharged to the external environment through the exhaust gap 103 and the air inlet 102, respectively. Since the nasal irrigator 100 of this utility model does not use a miniature air pump, it is not limited by the power supply and can work in environments with power outages or no power, greatly expanding the user's usage scenarios. At the same time, by reducing the use of vulnerable parts such as motors and bearings, the risk of wear or failure can be reduced even with frequent use, thereby effectively extending the service life of the nasal irrigator 100.
[0080] The above description is merely an exemplary embodiment of the present utility model and does not limit the patent scope of the present utility model. Any equivalent structural transformations made based on the technical concept of the present utility model and the contents of the present utility model specification and drawings, or direct / indirect applications in other related technical fields, are included within the patent protection scope of the present utility model.
