[0002] Existing nasal irrigators clean the nasal cavity by spraying atomized water droplets of varying sizes from the nasal nozzle. However, due to the limited reach of the nasal cavity, not all droplets, whether large or small, are effectively utilized after being sprayed simultaneously. Some droplets even evaporate before they have a chance to clean the nasal cavity, affecting the cleaning effect and resulting in waste of the cleaning solution. Utility Model Content

[0003] The main purpose of this invention is to provide a nasal irrigator, a nebulized nasal irrigator, and a nebulized nasal irrigator device, with the aim of extending the battery life of the nebulized nasal irrigator.

[0004] To achieve the above objectives, the present invention proposes a nasal irrigation head for use in a nebulized nasal irrigator. The nebulized nasal irrigator includes a housing, which has a stock solution chamber and a collection chamber.

[0006] An atomizing element is installed on the housing. The atomizing element and the nasal irrigation cap are connected to form a receiving cavity communicating with the nasal irrigation opening. The receiving cavity is used to communicate with the collection cavity. The atomizing element forms a first atomizing channel and a second atomizing channel that communicate with each other. The first atomizing channel is oriented towards and spaced apart from the nasal irrigation opening. The second atomizing channel is used to communicate with the original liquid cavity. The cross-sectional area of ​​the second atomizing channel gradually increases from the end closer to the nasal irrigation opening to the end farther away from the nasal irrigation opening. The cross-sectional area of ​​the second atomizing channel is larger than the cross-sectional area of ​​the first atomizing channel.

[0007] In one embodiment, the first atomizing channel is a cylindrical channel.

[0008] In one embodiment, the nasal irrigation cap has a nasal irrigation opening at the middle of one end, and a liquid storage tank is recessed at the edge of the other end of the nasal irrigation cap. The bottom wall of the liquid storage tank has a drain outlet communicating with the accommodating cavity.

[0009] In one embodiment, the liquid storage tank is an annular tank;

[0010] And / or, the number of drainage ports is multiple, and the multiple drainage ports are arranged at intervals along the circumference of the nasal irrigation cap.

[0011] This utility model also proposes a nebulized nasal irrigator, comprising:

[0012] The housing is provided with a raw liquid chamber and a collection chamber. The raw liquid chamber is used to store the cleaning liquid, and the collection chamber is used to collect the cleaning liquid after use.

[0013] An air intake pipe, one end of which extends into the raw liquid chamber, and the other end is used to connect to an air source;

[0014] As described above, the nasal washer's accommodating cavity is connected to the collecting cavity, and the second atomizing channel of the nasal washer is connected to the original liquid cavity.

[0015] In one embodiment, the housing includes a housing body and a support. The housing body has a cavity, and the support is disposed in the cavity to divide the cavity into a raw liquid cavity and a collection cavity. The nasal irrigator includes a nasal irrigator cap and an atomizing element. One end of the atomizing element is engaged with the nasal irrigator cap to form a receiving cavity, and the other end of the atomizing element is engaged with the support to fix the nasal irrigator to the support.

[0016] In one embodiment, the atomizing element includes a substrate, the substrate having a first communication port, and an atomizing portion protruding from the side of the substrate facing the receiving cavity. The atomizing portion includes a first atomizing section and a second atomizing section. The first atomizing section has a first atomizing channel, and the second atomizing section has a second atomizing channel. The second atomizing channel communicates with the original liquid cavity via the first communication port, and the air outlet of the air inlet pipe extends into the second atomizing channel via the first communication port.

[0017] In one embodiment, the substrate is further provided with a first protrusion on the side facing the receiving cavity, and the nasal irrigation cap is provided with a first snap-fit ​​groove, which engages with the first protrusion to fix the nasal irrigation cap to the atomizing element.

[0018] And / or, the substrate has a second protrusion on the side opposite to the receiving cavity, the second protrusion has a second snap-fit ​​groove, the second snap-fit ​​groove engages with the edge of the bracket to fix the atomizing element to the bracket.

[0019] In one embodiment, the substrate is provided with a second communication port, the receiving cavity is connected to the collecting cavity via the second communication port, the cross-sectional area of ​​the second communication port is matched with the cross-sectional area of ​​the collecting cavity, the second communication port has a first edge and a second edge opposite to each other, and a reinforcing rib is provided between the first edge and the second edge.

[0020] This utility model also proposes a nebulized nasal irrigation device, including an air source and a nebulized nasal irrigator as described above, wherein the air inlet pipe of the nebulized nasal irrigator is connected to the air source.

[0021] The nasal rinsing head of this utility model includes a nasal rinsing cap and an atomizing component. The nasal rinsing cap can be installed on the housing and has a nasal rinsing opening. The atomizing component is connected to the nasal rinsing cap to form a receiving cavity that communicates with the nasal rinsing opening. The receiving cavity can be connected to a collection cavity to ensure that the cleaning solution can be effectively recycled after use. The unique feature is that the atomizing component has a first atomizing channel and a second atomizing channel, which are connected. The first atomizing channel is oriented towards and spaced apart from the nasal irrigation opening, and is used to spray out fine atomized droplets. The second atomizing channel is connected to the original liquid chamber, and its cross-sectional area gradually increases from the end closer to the nasal irrigation opening to the end farther away from the nasal irrigation opening, and is larger than the cross-sectional area of ​​the first atomizing channel. In this way, smaller atomized water droplets can pass smoothly through the smaller cross-sectional area of ​​the first atomizing channel and be sprayed out through the nasal irrigation opening for nasal cleaning, while larger atomized water droplets, due to their larger size and inertia, cannot pass directly through the first atomizing channel. Instead, they are blocked at the connection between the first and second atomizing channels and condense back into the original liquid chamber for reuse. This avoids the waste caused by large and small atomized water droplets being sprayed out together and evaporating before use, thereby improving the effective utilization rate of the cleaning solution in the atomizing nasal irrigator and extending the battery life of the atomizing nasal irrigator.

[0036] Existing nasal irrigators clean the nasal cavity by spraying atomized water droplets of varying sizes from the nasal nozzle. However, due to the limited reach of the nasal cavity, not all droplets, whether large or small, are effectively utilized after being sprayed simultaneously. Some droplets even evaporate before they have a chance to clean the nasal cavity, affecting the cleaning effect and resulting in waste of the cleaning solution.

[0037] To solve the above problems, this utility model proposes a nasal wash 100.

[0038] Please see Figure 1 and Figure 5 In one embodiment of this utility model, the nasal irrigation head 100 is used in a nebulized nasal irrigator 1000. The nebulized nasal irrigator 1000 includes a housing 200, which has a stock solution chamber 3011 and a collection chamber 3012. The stock solution chamber 3011 is used to store the cleaning solution, and the collection chamber 3012 is used to collect the used cleaning solution. The nasal irrigation head 100 includes:

[0039] Nasal irrigation cover 1 is used to be installed on the housing 200, and the nasal irrigation cover 1 is provided with a nasal irrigation opening 101;

[0040] Atomizing component 2 is installed on the housing 200. The atomizing component 2 and the nasal irrigation cap 1 are connected to form a receiving cavity 102 that communicates with the nasal irrigation opening 101. The receiving cavity 102 is used to communicate with the collection cavity 3012. The atomizing component 2 forms a first atomizing channel 201 and a second atomizing channel 202 that communicate with each other. The first atomizing channel 201 is oriented towards and spaced apart from the nasal irrigation opening 101. The second atomizing channel 202 is used to communicate with the original liquid cavity 3011. The cross-sectional area of ​​the second atomizing channel 202 gradually increases from the end closer to the nasal irrigation opening 101 to the end farther away from the nasal irrigation opening 101. The cross-sectional area of ​​the second atomizing channel 202 is larger than the cross-sectional area of ​​the first atomizing channel 201.

[0041] In this embodiment, the nasal irrigation head 100 is used in the nebulized nasal irrigator 1000. The nebulized nasal irrigator 1000 may include a housing 200, an air intake assembly, and the nasal irrigation head 100 of this embodiment. The housing 200 is provided with a pre-cleaning fluid chamber 3011 for storing cleaning fluid, such as saline solution. To collect the used cleaning fluid and prevent it from dripping directly from the nasal cavity onto the ground, clothing, or other surfaces, thus affecting the user's comfort during the nasal irrigation process, the housing 200 is also provided with a collection chamber 3012. The collection chamber 3012 and the pre-cleaning fluid chamber 3011 are arranged opposite each other along the length of the housing 200. The collection chamber 3012 can be used to collect the used cleaning fluid, giving it a dedicated place to go. Users do not have to worry about the used cleaning fluid having nowhere to drain or overflowing, making the entire nasal irrigation process smoother and more comfortable, and improving the user's overall experience. One end of the air inlet pipe 300 is connected to an air source to receive the gas output from the air source, while the other end of the air inlet pipe 300 extends into and connects to the raw liquid chamber 3011. Gas from an external air source can directly enter through the air inlet pipe 300, carrying out the cleaning fluid in the raw liquid chamber 3011, mixing it with the gas, and atomizing it into water vapor. Finally, this vapor is sprayed out through the nasal rinse head 100 to clean the nasal cavity. The nasal rinse head 100 can be installed on the top of the housing 200, corresponding to the positions of the raw liquid chamber 3011 and the collection chamber 3012.

[0042] The nasal irrigator 100 may include a nasal irrigation cap 1, which can be installed on the housing 200 by means of threads, snaps, or integral molding, and can form a raw liquid chamber 3011 and a collection chamber 3012 together with the housing 200. The nasal irrigation cap 1 has a nasal irrigation opening 101, which is the part that directly contacts the user's nasal cavity and is used to introduce the atomized cleaning solution into the nasal cavity for cleaning. To avoid the mixing of unused and used cleaning solutions and affecting the cleaning effect, the nasal irrigator 100 may also include an atomizing element 2, which can also be installed on the housing 200 by means of threads, snaps, or integral molding, and is connected to the nasal irrigation cap 1, together forming a receiving cavity 102. The receiving cavity 102 communicates with the nasal irrigation opening 101 and the collection chamber 3012 so that the used cleaning solution can be effectively collected, avoiding its leakage and causing inconvenience or contamination to the user. At the same time, it is not connected to the raw liquid chamber 3011, which can prevent unused cleaning solution from being contaminated by used cleaning solution.

[0043] Based on the above, the atomizing component 2 has a first atomizing channel 201 and a second atomizing channel 202. The first atomizing channel 201 and the second atomizing channel 202 are housed in the receiving cavity 102. The first atomizing channel 201 and the second atomizing channel 202 are connected. The first atomizing channel 201 is oriented towards and spaced apart from the nasal irrigation opening 101. The second atomizing channel 202 is connected to the original liquid chamber 3011, and its cross-sectional area is larger than that of the first atomizing channel 201. With this configuration, when the atomizing nasal irrigator 1000 is used, the gas from the external air source can enter the original liquid chamber 3011 through the air inlet pipe 300, carrying out the cleaning liquid in the original liquid chamber 3011 and mixing it with the gas to atomize it into water vapor. The smaller atomized water droplets in the water vapor can easily pass through the smaller cross-sectional area of ​​the first atomizing channel. The nasal irrigator 1000 sprays the nasal solution through the nasal inlet 101 for nasal cleaning. After use, the cleaning solution first flows back to the receiving chamber 102 through the gap between the nasal inlet 101 and the first atomizing channel 201, and then flows back to the collection chamber 3012 through the receiving chamber 102, thus collecting the used cleaning solution. At the same time, larger atomized water droplets in the water vapor, due to their larger size and inertia, cannot pass directly through the first atomizing channel 201. Instead, they are blocked at the connection between the first atomizing channel 201 and the second atomizing channel 202 and condense, flowing back to the original liquid chamber 3011 for reuse. This avoids the waste caused by large and small atomized water droplets being sprayed out together and evaporating before use, thereby improving the effective utilization rate of the cleaning solution of the nasal irrigator 1000 and extending the battery life of the nasal irrigator 1000. It should also be noted that the cross-sectional area of ​​the second atomizing channel 202 gradually increases from the end near the nasal irrigation opening 101 to the end away from the nasal irrigation opening 101. This is because as the cross-sectional area of ​​the second atomizing channel 202 gradually increases, the airflow speed will decrease accordingly. This deceleration helps large atomized water droplets to condense in the second atomizing channel 202 and sink due to gravity, rather than being carried out of the nasal irrigation opening 101 by the airflow. It also effectively filters out small atomized water droplets suitable for cleaning the nasal cavity, allowing them to be sprayed out smoothly through the first atomizing channel 201, while large atomized water droplets flow back to the original liquid chamber 3011 for reuse.

[0044] Please see Figure 2 In one embodiment of this utility model, the first atomizing channel 201 is a cylindrical channel.

[0045] In this embodiment, compared to the complex-shaped atomization channels of existing nasal irrigators 1000, such as the horn shape, the cylindrical channel of this embodiment can effectively reduce the noise generated during atomization. This is because the horn-shaped atomization channel may increase the noise level during atomization due to sound waves and amplification, while the vertical cylindrical channel of this embodiment helps maintain stable airflow and reduces unnecessary sound wave reflections, thereby achieving the effect of noise reduction. Furthermore, the cylindrical channel provides a more stable and controllable atomization path for the atomized water vapor to enter the nasal irrigation opening 101. This stability contributes to the consistency and uniformity of the atomized particles, resulting in more consistent droplet sizes and thus improving the nasal cavity cleaning effect. In addition, compared to the horn-shaped atomization channel, the cylindrical channel has a simpler structure, is easier to manufacture, and is easier to clean and maintain after long-term use, reducing user operating costs.

[0046] Please see Figure 1 and Figure 2 In one embodiment of the present invention, a nasal irrigation port 101 is provided in the middle of one end of the nasal irrigation cap 1, and a liquid storage tank 103 is recessed on the edge of the other end of the nasal irrigation cap 1. The bottom wall of the liquid storage tank 103 is provided with a drain port 104 that communicates with the accommodating cavity 102.

[0047] It is understandable that, since the nasal irrigation inlet 101 is positioned facing the first atomization channel 201, and the first atomization channel 201 is connected to the original liquid chamber 3011 via the second atomization channel 202, the used cleaning solution will more or less flow back to the original liquid chamber 3011 through the first atomization channel 201, causing contamination of the cleaning solution in the original liquid chamber 3011 and affecting the user's cleaning effect. Therefore, in this embodiment, a nasal irrigation port 101 is provided in the middle of one end of the nasal irrigation cap 1, while a liquid storage tank 103 is recessed at the edge of the other end of the nasal irrigation cap 1. The bottom wall of the liquid storage tank 103 is provided with a drain port 104 communicating with the receiving cavity 102. The drain port 104 is positioned towards the collection cavity 3012 and is offset from the original liquid cavity 3011. In this way, most of the used cleaning fluid will flow back to the liquid storage tank 103 through the outer wall of the nasal irrigation cap 1, and flow to the collection cavity 3012 through the drain port 104 and the receiving cavity 102 under the action of gravity, thereby realizing the collection of the used cleaning fluid. It is worth noting that when the volume of the used cleaning fluid exceeds the capacity of immediately flowing back to the collection cavity 3012 through the drain port 104 and the receiving cavity 102, the liquid storage tank 103 can serve as a temporary storage area to contain this additional used cleaning fluid. This can avoid the risk of used cleaning fluid overflowing or backflow, ensuring the cleanliness and normal operation of the nebulized nasal irrigator 1000.

[0048] Please see Figure 1 and Figure 2 In one embodiment of this utility model, the liquid storage tank 103 is an annular tank.

[0049] In this embodiment, the liquid storage tank 103 is an annular tank, meaning that the liquid storage tank 103 forms a closed ring structure around the central axis of the nasal irrigation cap 1. The annular tank increases the circumference and surface area of ​​the liquid storage tank 103, allowing more used cleaning fluid to flow into the liquid storage tank 103 from all directions, effectively collecting the cleaning fluid regardless of its angle of flow. Furthermore, because the annular tank is evenly distributed around the nasal irrigation cap 1, it helps to balance the distribution of cleaning fluid across the entire nasal irrigation cap 1, reducing the occurrence of tilting or instability of the nasal irrigator due to excessive localized fluid accumulation. In addition, the annular tank fully utilizes the space at the edge of the nasal irrigation cap 1 without occupying additional volume, while providing sufficient capacity to temporarily store cleaning fluid exceeding the immediate discharge capacity, avoiding the risk of overflow or backflow.

[0050] Please see Figure 1 and Figure 2 In one embodiment of this utility model, there are multiple drainage ports 104, which are spaced apart along the circumference of the nasal irrigation cap 1.

[0051] In this embodiment, multiple drain ports 104 are provided on the bottom wall of the annular groove, instead of a single drain port 104. These drain ports 104 are arranged at certain intervals along the circumference of the nasal irrigator. This ensures that the used cleaning fluid flowing into the annular groove from all directions can be discharged quickly and effectively, reducing the residence time of the cleaning fluid in the annular groove, thereby improving the response speed and working efficiency of the entire nebulized nasal irrigator 1000. Furthermore, increasing the number of drain ports 104 and arranging them reasonably can reduce the risk of affecting the overall nasal irrigation function due to blockage of a single drain port 104. Even if a drain port 104 is partially blocked, the remaining drain ports 104 can still maintain normal drainage operation, ensuring the normal operation of the nebulized nasal irrigator 1000.

[0052] This utility model also proposes a nebulizing nasal irrigator 1000, please refer to [link / reference needed]. Figures 3 to 6 The nebulized nasal irrigator 1000 includes a housing 200, an air inlet pipe 300, and a nasal irrigator head 100. The specific structure of the nasal irrigator head 100 is as described in the above embodiments. Since the nebulized nasal irrigator 1000 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. The housing 200 is provided with a raw liquid chamber 3011 and a collection chamber 3012. The raw liquid chamber 3011 is used to store the cleaning liquid, and the collection chamber 3012 is used to collect the cleaning liquid after use. One end of the air inlet pipe 300 extends into the raw liquid chamber 3011, and the other end of the air inlet pipe 300 is used to connect to an air source. The accommodating cavity 102 of the nasal irrigator head 100 is connected to the collection chamber 3012, and the second atomizing channel 202 of the nasal irrigator head 100 is connected to the raw liquid chamber 3011.

[0053] In this embodiment, when the atomizing nasal irrigator 1000 is used, the gas from the external air source can enter the original liquid chamber 3011 through the air inlet pipe 300, carrying out the cleaning liquid in the original liquid chamber 3011 and mixing it with the gas to atomize it into water vapor. The smaller atomized water droplets in the water vapor can smoothly pass through the first atomizing channel 201 with a smaller cross-section and be sprayed out through the nasal irrigator 101 for nasal cleaning. After use, the cleaning liquid will first flow back to the receiving chamber 102 through the gap between the nasal irrigator 101 and the first atomizing channel 201, and then flow back to the collection chamber 3 through the receiving chamber 102. 012 enables the collection of cleaning fluid after use. At the same time, larger atomized water droplets in the water vapor, due to their larger size and inertia, cannot pass directly through the first atomization channel 201. Instead, they are blocked at the connection between the first atomization channel 201 and the second atomization channel 202 and condense back into the original liquid chamber 3011 for reuse. This avoids the waste caused by large and small atomized water droplets being sprayed out together and evaporating before use, thereby improving the effective utilization rate of the cleaning fluid in the nasal irrigator 1000 and extending the battery life of the nasal irrigator 1000. It should also be noted that the cross-sectional area of ​​the second atomizing channel 202 gradually increases from the end near the nasal irrigation opening 101 to the end away from the nasal irrigation opening 101. This is because as the cross-sectional area of ​​the second atomizing channel 202 gradually increases, the airflow speed will decrease accordingly. This deceleration helps large atomized water droplets to condense in the second atomizing channel 202 and sink due to gravity, rather than being carried out of the nasal irrigation opening 101 by the airflow. It also effectively filters out small atomized water droplets suitable for cleaning the nasal cavity, allowing them to be sprayed out smoothly through the first atomizing channel 201, while large atomized water droplets flow back to the original liquid chamber 3011 for reuse.

[0054] Please see Figure 7 In one embodiment of the present invention, the housing 200 includes a housing body 3 and a support 4. The housing body 3 is provided with a cavity 301. The support 4 is provided in the cavity 301 to divide the cavity 301 into a liquid cavity 3011 and a collection cavity 3012. The nasal wash head 100 includes a nasal wash cap 1 and an atomizing element 2. One end of the atomizing element 2 is snapped into the nasal wash cap 1 to form a receiving cavity 102. The other end of the atomizing element 2 is snapped into the support 4 to fix the nasal wash head 100 to the support 4.

[0055] In this embodiment, the shell body 3 is the outer casing of the atomizing nasal irrigator 1000, and an internal cavity 301 is provided. A bracket 4 is installed in the cavity 301, dividing it into a raw liquid cavity 3011 and a collection cavity 3012. This not only effectively separates unused and used cleaning liquid but also makes the overall structure of the atomizing nasal irrigator 1000 more compact. The nasal irrigation cap 1 is located at the end of the atomizing element 2 away from the shell body 3 and has a nasal irrigation nozzle 101. The nasal irrigation nozzle 101 is used to spray atomized water vapor into the nasal cavity to achieve nasal cleaning. The end of the atomizing element 2 away from the shell body 3 is engaged with the nasal irrigation cap 1 to form a receiving cavity 102. The end of the atomizing element 2 near the shell body 3 is engaged with the bracket 4 to fix the entire nasal irrigation head 100 on the bracket 4, improving the stability and reliability of the atomizing nasal irrigator 1000 during use. In other words, when assembling the nasal irrigator 1000, the nasal irrigator cap 1 can be snapped into the nasal irrigator component 2 to form the nasal irrigator head 100, and then the nasal irrigator component 2 can be snapped into the bracket 4. The installation / removal of the nasal irrigator 1000 can be completed quickly without complicated tools, making it convenient for users to maintain and clean themselves.

[0056] Please see Figure 7 In one embodiment of the present invention, the atomizing component 2 includes a substrate 21, the substrate 21 is provided with a first communication port 203, and an atomizing part 22 is protruding on the side of the substrate 21 facing the accommodating cavity 102. The atomizing part 22 includes a first atomizing section 221 and a second atomizing section 222. The first atomizing section 221 has a first atomizing channel 201, and the second atomizing section 222 has a second atomizing channel 202. The second atomizing channel 202 is connected to the original liquid cavity 3011 through the first communication port 203, and the air outlet end of the air inlet pipe 300 extends into the second atomizing channel 202 through the first communication port 203.

[0057] In this embodiment, the atomizing component 2 includes a substrate 21 and an atomizing section 22. The substrate 21 is provided with a first connecting port 203, which mainly serves to connect the second atomizing channel 202 with the air inlet pipe 300 and the raw liquid chamber 3011, so that the cleaning liquid in the raw liquid chamber 3011 can mix with the gas in the air inlet pipe 300 to form water vapor and smoothly enter the second atomizing channel 202. The atomizing section 22 is located on the side of the substrate 21 facing the receiving cavity 102 and protrudes from the substrate 21. The atomizing section 22 includes a first atomizing segment 221 and a second atomizing segment 222, both of which extend along the length direction of the shell body 3. The first atomizing segment 221 is positioned closer to the nasal washing mouth 101 than the second atomizing segment 222. The first atomizing section 221 has a first atomizing channel 201, which is directly facing the nasal irrigation opening 101, used to spray small atomized water droplets into the nasal irrigation opening 101, and then carry them out into the nasal cavity. The second atomizing section 222 has a second atomizing channel 202, which is connected to the air inlet pipe 300 and the original liquid chamber 3011 through a first connecting port 203, and receives atomized water droplets after the cleaning liquid from the original liquid chamber 3011 and the gas from the air inlet pipe 300 are mixed. The air outlet of the air inlet pipe 300 passes through the first connecting port 203 and extends into the second atomizing channel 202, which can more effectively promote the mixing process of the cleaning liquid and gas, thereby improving the efficiency and uniformity of atomization.

[0058] Please see Figure 7 In one embodiment of this utility model, the substrate 21 has a first protrusion 23 protruding on the side facing the receiving cavity 102, and the nasal irrigation cap 1 has a first snap-fit ​​groove 105. The first snap-fit ​​groove 105 engages with the first protrusion 23 to fix the nasal irrigation cap 1 to the atomizing element 2. By inserting the first protrusion 23 into and snapping it into the first snap-fit ​​groove 105, the nasal irrigation cap 1 can be firmly fixed to the atomizing element 2, forming a complete nasal irrigation head 100.

[0059] In another embodiment, a second protrusion 24 is provided on the side of the substrate 21 opposite to the receiving cavity 102. The second protrusion 24 is provided with a second snap-fit ​​groove 204, which engages with the edge of the bracket 4 to fix the atomizing element 2 to the bracket 4. By inserting the edge of the bracket 4 into the second snap-fit ​​groove 204, the atomizing element 2 can be stably installed on the bracket 4, ensuring that the entire nasal rinse head 100 is fixed in position and not easily loosened.

[0060] In other words, when assembling the nasal irrigator 1000, the first protrusion 23 can be engaged with the first snap-fit ​​groove 105 to connect the nasal irrigator cover 1 and the atomizing component 2 together to form a complete nasal irrigator head 100. Then, the edge of the bracket 4 is engaged with the second snap-fit ​​groove 204 to install the entire nasal irrigator head 100 on the bracket 4. The installation / removal of the nasal irrigator 1000 can be completed quickly without complicated tools, making it convenient for users to maintain and clean themselves.

[0061] Please see Figure 7 In one embodiment of the present invention, the substrate 21 is provided with a second communication port 205, the accommodating cavity 102 is connected to the collecting cavity 3012 via the second communication port 205, the cross-sectional area of ​​the second communication port 205 is matched with the cross-sectional area of ​​the collecting cavity 3012, the second communication port 205 has a first edge 2051 and a second edge 2052 opposite to each other, and a reinforcing rib 25 is provided between the first edge 2051 and the second edge 2052.

[0062] In this embodiment, the substrate 21 is provided with a second communication port 205 for connecting the receiving cavity 102 and the collecting cavity 3012. The cross-sectional area of ​​the second communication port 205 is designed to match the cross-sectional area of ​​the collecting cavity 3012, so that the cleaning fluid after use can flow smoothly from the receiving cavity 102 into the collecting cavity 3012, avoiding the problems of blockage or slow flow rate caused by the second communication port 205 being too narrow. Since the diameter of the second communication port 205 is larger when the cross-sectional area of ​​the second communication port 205 matches the cross-sectional area of ​​the collecting cavity 3012, this would reduce the structural strength of the substrate 21. Therefore, in this embodiment, the second communication port 205 has a first edge 2051 and a second edge 2052, and a reinforcing rib 25 is connected between the first edge 2051 and the second edge 2052. The reinforcing rib 25 can not only improve the overall structural strength of the substrate 21, but also maintain the shape stability of the second communication port 205, preventing deformation caused by external pressure or internal cleaning fluid flow during use.

[0063] This utility model also proposes a nebulized nasal irrigation device; please refer to [link / reference]. Figure 6 and Figure 7 The nebulized nasal irrigator includes an air source and a nebulized nasal irrigator 1000. The specific structure of the nebulized nasal irrigator 1000 is as described in the above embodiments. Since this nebulized nasal irrigator 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.

[0064] 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. The air source is connected to the air inlet pipe 300 of the nebulizer nasal irrigator 1000. In practical applications, when the nebulizer nasal irrigator 1000 is used, the gas from the external air source can enter the original liquid chamber 3011 through the air inlet pipe 300, carrying out the cleaning liquid in the original liquid chamber 3011 and mixing it with the gas to atomize it into water vapor. The smaller atomized water droplets in the water vapor can smoothly pass through the first atomization channel 201 with a smaller cross-section and be sprayed out through the nasal irrigation mouth 101 for nasal cleaning. After use, the cleaning liquid will first flow back to the receiving chamber 102 through the gap between the nasal irrigation mouth 101 and the first atomization channel 201, and then flow back to the collection chamber 3 through the receiving chamber 102. 012 enables the collection of cleaning fluid after use. At the same time, larger atomized water droplets in the water vapor, due to their larger size and inertia, cannot pass directly through the first atomization channel 201. Instead, they are blocked at the connection between the first atomization channel 201 and the second atomization channel 202 and condense back into the original liquid chamber 3011 for reuse. This avoids the waste caused by large and small atomized water droplets being sprayed out together and evaporating before use, thereby improving the effective utilization rate of the cleaning fluid in the nasal irrigator 1000 and extending the battery life of the nasal irrigator 1000.

[0065] 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.
