Description

Technical Field

[0001] This utility model relates to the field of medical equipment technology, and in particular to a nebulizer nasal irrigator and a nebulizer nasal irrigator device. Background Technology

[0002] Most nasal irrigators on the market currently do not separate unused and used nasal solutions into distinct chambers. This allows used solution to flow back into the original chamber and mix with clean solution, reducing the effectiveness of subsequent cleaning and posing potential hygiene and safety hazards. Furthermore, the nasal irrigator caps of these devices are typically connected to the housing via threads. After prolonged use, these threads can wear down, leading to instability and affecting the overall structural stability and sealing performance. Utility Model Content

[0003] The main purpose of this utility model is to propose a nebulized nasal irrigator and a nebulized nasal irrigator device, which aims to improve the hygiene and safety of the nebulized nasal irrigator and its cleaning effect, while also ensuring its structural stability and sealing reliability.

[0004] To achieve the above objectives, the present invention provides a nebulizing nasal irrigator comprising:

[0005] The housing has a cavity and a mounting port communicating with the cavity;

[0006] A support is provided in the cavity to divide the cavity into a raw liquid cavity and a collection cavity;

[0007] The nasal rinse head includes a nasal rinse cap and an atomizing element. One end of the atomizing element is inserted into the cavity wall of the cavity through the mounting port and snapped into the bracket. The other end of the atomizing element extends out of the housing and snaps into the nasal rinse cap to form a receiving cavity that communicates with the original liquid cavity and the collection cavity. The edge of the nasal rinse cap is snapped into the edge of the mounting port.

[0008] In one embodiment, the atomizing element includes:

[0009] substrate;

[0010] A first protrusion is provided on the edge of the substrate on the side opposite to the receiving cavity. The first protrusion is inserted into the cavity wall of the cavity through the mounting port. The first protrusion has a first mounting groove and a second mounting groove.

[0011] The second protrusion has two ends respectively engaged in the first mounting groove and the second mounting groove. The second protrusion has a first snap-fit ​​groove, which engages with the bracket to fix the atomizing element to the bracket.

[0012] In one embodiment, the second protrusion has opposing first and second sides, which abut against the cavity wall of the cavity.

[0013] In one embodiment, the atomizing element further includes:

[0014] The third protrusion is located on the edge of the substrate facing the receiving cavity. The nasal irrigation cap is provided with a second snap-fit ​​groove, which engages with the third protrusion to form the receiving cavity by the nasal irrigation cap and the substrate, and is fixed to the substrate.

[0015] In one embodiment, the atomizing element further includes:

[0016] A positioning rib, one end of which is located on the first protrusion and the other end of which is located on the third protrusion, is positioned toward the cavity wall of the cavity.

[0017] In one embodiment, a plurality of positioning ribs are provided, and the plurality of positioning ribs are spaced apart along the circumference of the atomizing element.

[0018] In one embodiment, the positioning rib has a positioning surface that is inclined upward from the end near the first protrusion toward the end away from the first protrusion.

[0019] In one embodiment, the atomizing element further includes:

[0020] The first atomizing section is located in the middle of the side of the substrate facing the accommodating cavity, and the first atomizing section has a first atomizing channel communicating with the original liquid cavity;

[0021] The second atomizing section is located in the first atomizing section. The nasal washing cap is provided with a nasal washing opening. The second atomizing section has a second atomizing channel facing the nasal washing opening and communicating with the first atomizing channel.

[0022] In one embodiment, the nasal irrigation cap has a nasal irrigation opening at the middle of the end away from the atomizing element, and a liquid storage tank is recessed at the edge of the end of the nasal irrigation cap near the atomizing element. The bottom wall of the liquid storage tank has a drain outlet communicating with the accommodating cavity.

[0023] This utility model also proposes a nebulized nasal irrigation device, including the nebulized nasal irrigation device as described above.

[0024] The technical solution of this utility model separates the cavity into an independent original liquid cavity and a collection cavity by setting a support inside the shell. This achieves separate storage of unused cleaning solution and used cleaning solution, effectively preventing the used cleaning solution from flowing back into the original liquid cavity and causing cross-contamination, thereby improving the cleaning effect and hygiene safety. Simultaneously, the nasal irrigation head of this atomizing nasal irrigator consists of a nasal irrigation cap and an atomizing element. One end of the atomizing element is inserted into the shell cavity through the mounting port and fixed to the cavity wall and support, making the atomizing element firmly integrated into the shell; the other end extends outside the shell and engages with the nasal irrigation cap. Together, they form a receiving cavity that communicates with both the original liquid cavity and the collection cavity. This design not only ensures reliable fixation of the nasal irrigation cap but also allows the edge of the nasal irrigation cap to engage with the edge of the mounting port, further enhancing the sealing performance between the nasal irrigation head and the shell and the stability of the overall structure. This fundamentally avoids the wear and loosening problems caused by long-term use of traditional threaded connections, improving the safety and reliability of the atomizing nasal irrigator during use.

[0033] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the scope of protection of the present utility model.

[0034] It should be noted that if the embodiments of this utility model involve directional indicators (such as up, down, left, right, front, back, etc.), the directional indicators are only used to explain the relative positional relationship and movement of the components in a specific posture. If the specific posture changes, the directional indicators will also change accordingly.

[0035] Furthermore, if the embodiments of this utility model involve descriptions such as "first" or "second," these descriptions are 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 with "first" or "second" may explicitly or implicitly include at least one of those features. Additionally, the use of "and / or" or "and / or" throughout the text includes three parallel solutions. For example, "A and / or B" includes solution A, solution B, or a solution where both A and B are satisfied simultaneously. Furthermore, the technical solutions of the various embodiments can be combined with each other, but this must be based on the ability of those skilled in the art to implement them. When the combination of technical solutions is contradictory or impossible to implement, it should be considered that such a combination of technical solutions does not exist and is not within the scope of protection claimed by this utility model.

[0036] Most nasal irrigators on the market currently do not separate unused and used nasal solutions into distinct chambers. This allows used solution to flow back into the original chamber and mix with clean solution, reducing the effectiveness of subsequent cleaning and posing potential hygiene and safety hazards. Furthermore, the nasal irrigator caps of these devices are typically connected to the housing via threads. After prolonged use, these threads can wear down, leading to instability and affecting the overall structural stability and sealing performance.

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

[0038] Please see Figure 1 and Figure 2 In one embodiment of this utility model, the nebulizing nasal irrigator 100 includes:

[0039] The housing 1 has a cavity 101 and a mounting port 102 communicating with the cavity 101;

[0040] A support 2 is provided in the cavity 101 to divide the cavity 101 into a raw liquid cavity 1011 and a collection cavity 1012;

[0041] The nasal rinse tip 3 includes a nasal rinse cap 31 and an atomizing element 32. One end of the atomizing element 32 is inserted into the cavity wall of the cavity 101 via the mounting port 102 and is snapped onto the bracket 2. The other end of the atomizing element 32 extends out of the housing 1 and snaps onto the nasal rinse cap 31 to form a receiving cavity 301 that communicates with the original liquid cavity 1011 and the collection cavity 1012. The edge of the nasal rinse cap 31 is snapped onto the edge of the mounting port 102.

[0042] In this embodiment, the atomizing nasal irrigator 100 may include a housing 1, a nasal irrigation head 3, and an air inlet tube 4. The housing 1 has a cavity 101 and an installation port 102 communicating with the cavity 101. The cavity 101 is a space for containing cleaning fluid, and the installation port 102 is used to install the nasal irrigation head 3. The nasal irrigation head 3 is installed on the top of the housing 1 and may include a nasal irrigation cap 31 communicating with the cavity 101 and the air inlet tube 4. One end of the air inlet tube 4 extends into and communicates with the cavity 101, and the other end of the air inlet tube 4 is used to communicate with an external air source. Gas from the external air source can enter through the air inlet tube 4, carry out the cleaning fluid in the cavity 101, mix it with the gas, atomize it into water vapor, and finally spray it out through the nasal irrigation cap 31 to clean the user's nasal cavity.

[0043] However, since the nasal irrigation cap 31 is directly connected to the cavity 101, the used cleaning solution will flow back into the nasal irrigation cap 31 through the nasal irrigation port 308, and then flow back into the cavity 101 through the inner wall of the nasal irrigation cap 31. At this time, the unused cleaning solution in the cavity 101 will mix with the used cleaning solution, which will not only affect the subsequent cleaning effect, but also pose certain hygiene and safety hazards.

[0044] Therefore, the nebulized nasal irrigator 100 of this embodiment also includes a support 2, which is installed in the cavity 101 to divide the cavity 101 into a liquid chamber 1011 and a collection chamber 1012. The liquid chamber 1011 and the collection chamber 1012 are arranged opposite to each other along the length of the shell 1. The liquid chamber 1011 is used to store the cleaning solution, and the collection chamber 1012 is used to collect the used cleaning solution, giving the used cleaning solution a dedicated place to go, effectively preventing the used cleaning solution from mixing with the unused cleaning solution, effectively improving the user's cleaning effect, and reducing hygiene and safety hazards. At the same time, the user does not need to worry too much about the used cleaning solution having nowhere to drain or overflowing, making the entire nasal irrigation process smoother and more comfortable, and improving the user's overall experience.

[0045] To prevent the used cleaning solution from flowing back into the original solution chamber 1011 through the nasal irrigation cap 31, the nasal irrigation head 3 in this embodiment also includes an atomizing element 32. The atomizing element 32 is located inside the nasal irrigation cap 31. One end of the atomizing element 32 near the housing 1 is inserted into the cavity wall of the cavity 101 through the mounting port 102 to seal the mounting port 102, that is, to seal the gap between the nasal irrigation head 3 and the housing 1. At the same time, this end is snapped into the bracket 2, so that the atomizing element 32 can be integrated into the housing 1. One end of the atomizing element 32, away from the housing 1, extends out of the housing 1 and engages with the nasal irrigation cap 31 to form a receiving cavity 301. The receiving cavity 301 is used to receive the first atomizing section 326 and the second atomizing section 327 of the nasal irrigation head 3. The first atomizing section 326 and the second atomizing section 327 are connected. One end of the second atomizing section 327 can be connected to the nasal irrigation opening 308 of the nasal irrigation cap 31 through the receiving cavity 301. The other end of the second atomizing section 327 is connected to the air inlet pipe 4 and the original liquid chamber 1011 through the first atomizing section 326, so that the gas in the air inlet pipe 4 and the cleaning liquid in the original liquid chamber 1011 are mixed into water vapor, which then flows through the first atomizing section 326 and the second atomizing section 327 to the nasal irrigation opening 308, and is then sprayed out from the nasal irrigation opening 308 to the user's nasal cavity to clean the user's nasal cavity. At the end of the atomizing element 32 near the housing 1, the atomizing element 32 is also provided with a communication port, and the accommodating cavity 301 can be connected to the collecting cavity 1012 through the communication port, so that the cleaning fluid after use can flow back to the collecting cavity 1012 through the nasal irrigation port 308 and the accommodating cavity 301.

[0046] When the atomizing component 32 and the nasal irrigation cap 31 are engaged, the edge of the nasal irrigation cap 31 can engage with the edge of the mounting port 102, further enhancing the sealing performance between the nasal irrigation head 3 and the housing 1 and the stability of the overall structure. This fundamentally avoids the wear and loosening problems caused by long-term use of traditional threaded connections, and improves the safety and reliability of the atomizing nasal irrigator 100 during use.

[0047] Please see Figure 3 and Figure 4 In one embodiment of this utility model, the atomizing element 32 includes:

[0048] substrate 321;

[0049] The first protrusion 322 is provided on the edge of the substrate 321 on the side away from the receiving cavity 301. The first protrusion 322 is inserted into the cavity wall of the cavity 101 through the mounting port 102. The first protrusion 322 has a first mounting groove 302 and a second mounting groove 303.

[0050] The second protrusion 323 has two ends respectively engaged in the first mounting groove 302 and the second mounting groove 303. The second protrusion 323 is provided with a first snap-fit ​​groove 304, which engages with the bracket 2 to fix the atomizing element 32 to the bracket 2.

[0051] In this embodiment, the atomizing element 32 includes a substrate 321, a first protrusion 322, and a second protrusion 323. The first protrusion 322 is disposed on the edge of the substrate 321 facing away from the receiving cavity 301. The first protrusion 322 is inserted into the cavity wall of the cavity 101 via the mounting port 102 to seal the mounting port 102, that is, to seal the gap between the nasal rinse head 3 and the housing 1. The first protrusion 322 is a circular protrusion, and the mounting port 102 is a circular opening. The matching shapes of the two can further reduce the gap between the nasal rinse head 3 and the housing 1. The first protrusion 322 has a first mounting groove 302 and a second mounting groove 303 facing towards the housing 1. The two ends of the second protrusion 323 are respectively engaged in the first mounting groove 302 and the second mounting groove 303 to fix the second protrusion 323 to the substrate 321. The second protrusion 323 has a first snap-fit ​​groove 304 on the side facing the housing 1. The first snap-fit ​​groove 304 is snap-fitted with the bracket 2, which can fix the substrate 321, the first protrusion 322 and the second protrusion 323 together to the bracket 2, that is, integrate the atomizing element 32 into the bracket 2.

[0052] Please see Figure 3 and Figure 4 In one embodiment of the present invention, the second protrusion 323 has a first side 3231 and a second side 3232 opposite to each other, and the first side 3231 and the second side 3232 abut against the cavity wall of the cavity 101.

[0053] In this embodiment, by abutting the second protrusion 323 against the cavity wall of the cavity 101 relative to the first side 3231 and the second side 3232, a secondary fixation is achieved by means of the cavity wall of the cavity 101 on the basis of fixing the second protrusion 323 to the bracket 2, thereby further improving the stability of the atomizing element 32 integrated into the bracket 2.

[0054] Please see Figure 3 and Figure 4 In one embodiment of this utility model, the atomizing element 32 further includes:

[0055] The third protrusion 324 is located on the edge of the substrate 321 facing the receiving cavity 301. The nasal washing cover 31 is provided with a second snap-fit ​​groove 305. The second snap-fit ​​groove 305 engages with the third protrusion 324 so that the nasal washing cover 31 and the substrate 321 surround and form the receiving cavity 301, and are fixed to the substrate 321.

[0056] In this embodiment, to achieve the connection between the nasal irrigation cap 31 and the substrate 321, the atomizing element 32 further includes a third protrusion 324. The third protrusion 324 is located on the edge of the substrate 321 facing the receiving cavity 301. The nasal irrigation cap 31 has a second snap-fit ​​groove 305 at one end near the housing 1 and facing the housing 1. The second snap-fit ​​groove 305 engages with the third protrusion 324, which can fix the nasal irrigation cap 31 to the substrate 321 and make the edge of the nasal irrigator fit with the edge of the mounting port 102, thereby achieving a secondary seal for the gap between the nasal irrigation head 3 and the housing 1.

[0057] As can be seen from the above embodiments, during the assembly of the nebulized nasal irrigator 100, the first snap-fit ​​groove 304 of the second protrusion 323 can be snapped into the bracket 2 to fix the atomizing element 32 to the bracket 2. At this time, the atomizing element 32 has been integrated with the housing 1. Then, the third protrusion 324 can be snapped into the second snap-fit ​​groove 305 of the nasal irrigator cover 31, and at the same time, the edge of the nasal irrigator cover 31 can be snapped into the edge of the mounting port 102. Thus, the nasal irrigator cover 31 can be integrated on both the atomizing element 32 and the housing 1, thereby completing the assembly of all components of the nebulized nasal irrigator 100.

[0058] Please see Figure 3 and Figure 4 In one embodiment of this utility model, the atomizing element 32 further includes:

[0059] The positioning rib 325 has one end located on the first protrusion 322 and the other end located on the third protrusion 324. The positioning rib 325 is positioned towards the cavity wall of the cavity 101.

[0060] In this embodiment, to ensure a tight fit between the atomizing element 32 and the nasal irrigation cap 31 and the housing 1, and to reduce assembly difficulty, the atomizing element 32 also includes a positioning rib 325. One end of the positioning rib 325 is located on the side of the first protrusion 322 facing the cavity wall of the cavity 101, and is positioned between the first protrusion 322 and the cavity wall of the cavity 101. When assembling the atomizing element 32 with the housing 1, i.e., when the first protrusion 322 is inserted into the mounting port 102 of the cavity 101 of the housing 1, the positioning rib 325 can play a guiding, adjusting, and buffering role during the assembly process. Due to its certain elastic deformation capability, the positioning rib 325 can automatically adjust within a certain dimensional tolerance range, thereby compensating for deviations caused by manufacturing errors or material shrinkage. This not only helps the first protrusion 322 to be smoothly inserted and stably fixed in the cavity 101, but also effectively avoids loosening problems caused by excessive gaps or insertion difficulties caused by excessively small gaps, significantly improving the fault tolerance of the assembly process and the consistency of the product. The other end of the positioning rib 325 is located on the side of the third protrusion 324 facing the inner wall of the nasal irrigation cap 31, and is situated between the third protrusion 324 and the inner wall of the nasal irrigation cap 31. The inner wall of the nasal irrigation cap 31 mainly refers to the groove wall of the second snap-fit ​​groove 305. During the assembly of the atomizing component 32 and the nasal irrigation cap 31, i.e., when the third protrusion 324 is inserted into the second snap-fit ​​groove 305 of the nasal irrigation cap 31, the positioning rib 325 plays a similar role: through its own fine-tuning function, it compensates for possible dimensional deviations, ensuring that the third protrusion 324 can be accurately and smoothly embedded in the second snap-fit ​​groove 305, thereby improving the connection stability and sealing performance of the two.

[0061] Please see Figure 3 and Figure 4 In one embodiment of this utility model, multiple positioning ribs 325 are provided, and the multiple positioning ribs 325 are arranged at intervals along the circumference of the atomizing member 32.

[0062] In this embodiment, there are multiple positioning ribs 325, rather than a single positioning rib 325. The multiple positioning ribs 325 are evenly distributed circumferentially along the atomizing element 32, and each of the multiple positioning ribs 325 is simultaneously located on both the first protrusion 322 and the third protrusion 324. This arrangement can compensate for dimensional deviations caused by manufacturing errors or material shrinkage in different directions, ensuring sealing performance in all directions. Because the positioning ribs 325 can automatically adjust for minute dimensional differences, even with certain manufacturing tolerances, it ensures that the first protrusion 322 smoothly inserts into the mounting port 102 and the third protrusion 324 accurately inserts into the second snap-fit ​​groove 305, thereby reducing assembly difficulty and minimizing assembly problems caused by excessive tightness or looseness.

[0063] Please see Figure 3 and Figure 4In one embodiment of the present invention, the positioning rib 325 has a positioning surface 3251, which is inclined upward from the end near the first protrusion 322 toward the end away from the first protrusion 322.

[0064] In this embodiment, each positioning rib 325 has a positioning surface 3251, which gradually slopes upwards from the side closest to the first protrusion 322 towards the side furthest from the first protrusion 322. This means that as the positioning rib 325 is inserted into the mounting port 102, the positioning surface 3251 guides the atomizing element 32 to gradually align in the correct position and automatically adjusts for any minor deviations through its inclined design. Furthermore, when there is slight assembly pressure, the inclined positioning surface 3251 can provide a certain buffering effect, preventing damage caused by hard contact between the first protrusion 322 and the cavity wall of the cavity 101, while ensuring a tight connection.

[0065] Please see Figure 3 and Figure 4 In one embodiment of this utility model, the atomizing element 32 further includes:

[0066] The first atomizing section 326 is located in the middle of the side of the substrate 321 facing the accommodating cavity 301, and the first atomizing section 326 has a first atomizing channel 306 communicating with the original liquid cavity 1011.

[0067] The second atomizing section 327 is located in the first atomizing section 326. The nasal washing cover 31 is provided with a nasal washing opening 308. The second atomizing section 327 has a second atomizing channel 307 that faces the nasal washing opening 308 and is connected to the first atomizing channel 306.

[0068] In this embodiment, to guide the water vapor formed by mixing the gas from the air inlet pipe 4 and the cleaning liquid from the original liquid chamber 1011 to the nasal irrigation port 308 of the nasal irrigation cap 31, the atomizing element 32 further includes a first atomizing section 326 and a second atomizing section 327, which are located in the receiving cavity 301. It can be understood that the receiving cavity 301 provides space to accommodate the first atomizing section 326 and the second atomizing section 327. The first atomizing section 326 is located in the middle of the side of the substrate 321 facing the receiving cavity 301, that is, the first atomizing section 326 occupies the middle position of the substrate 321, while the third protrusion 324 occupies the edge position of the substrate 321, thus maximizing the utilization of the mounting area of ​​the substrate 321. The first atomizing section 326 has a first atomizing channel 306 communicating with the original liquid chamber 1011. The second atomizing section 327 is located above the first atomizing section 326. The second atomizing section 327 is connected to the first atomizing section 326. The second atomizing section 327 has a second atomizing channel 307. One end of the second atomizing channel 307 is connected to the first atomizing channel 306, and the other end of the second atomizing channel 307 is connected to the receiving cavity 301 and is positioned towards the nasal irrigation mouth 308.

[0069] It is worth noting that the cross-sectional area of ​​the first atomizing channel 306 is larger than that of the second atomizing channel 306. When the nasal irrigator 100 is used, the gas from the external air source can enter the original liquid chamber 1011 through the air inlet pipe 4, carrying out the cleaning liquid in the original liquid chamber 1011 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 second atomizing channel 307 with a smaller cross-section and be sprayed out through the nasal irrigation mouth 308 for nasal cleaning of the user. After use, the cleaning liquid will first flow back to the receiving chamber 301 through the gap between the nasal irrigation mouth 308 and the first atomizing channel 306, and then flow back to the collecting chamber 101 through the receiving chamber 301. 2. To achieve 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, are difficult to pass directly through the second atomization channel 307. Instead, they are blocked at the connection between the first atomization channel 306 and the second atomization channel 307 and condense back into the original liquid chamber 1011 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 of the nasal irrigator 100 and extending the battery life of the nasal irrigator 100. It should also be noted that the cross-sectional area of ​​the first atomizing channel 306 gradually increases from the end near the nasal irrigation opening 308 to the end away from the nasal irrigation opening 308. This is because as the cross-sectional area of ​​the first atomizing channel 306 gradually increases, the airflow speed will decrease accordingly. This deceleration helps large atomized water droplets to condense in the first atomizing channel 306 and sink due to gravity, rather than being carried out of the nasal irrigation opening 308 by the airflow. It also effectively filters out small atomized water droplets suitable for nasal cleaning, allowing them to be smoothly sprayed out through the second atomizing channel 307, while large atomized water droplets flow back to the original liquid chamber 1011 for reuse.

[0070] Please see Figure 3 and Figure 4 In one embodiment of the present invention, a nasal irrigation port 308 is provided in the middle of the end of the nasal irrigation cap 31 away from the atomizing element 32, and a liquid storage tank 309 is recessed on the edge of the end of the nasal irrigation cap 31 near the atomizing element 32. The bottom wall of the liquid storage tank 309 is provided with a drain port 310 communicating with the accommodating cavity 301.

[0071] In this embodiment, since the nasal irrigation mouth 308 is positioned towards the second atomization channel 307, and the second atomization channel 307 is connected to the original liquid chamber 1011 via the first atomization channel 306, the used cleaning fluid will more or less flow back to the original liquid chamber 1011 via the second atomization channel 307, causing contamination of the cleaning fluid in the original liquid chamber 1011 and affecting the user's cleaning effect. Therefore, in this embodiment, a nasal irrigation port 308 is provided in the middle of the end of the nasal irrigation cap 31 away from the atomizing element 32, and a liquid storage tank 309 is recessed on the edge of the end of the nasal irrigation cap 31 near the atomizing element 32. The bottom wall of the liquid storage tank 309 is provided with a drain port 310 communicating with the receiving cavity 301. The drain port 310 is positioned towards the collection cavity 1012 and is offset from the original liquid cavity 1011. In this way, most of the used cleaning fluid will flow back to the liquid storage tank 309 through the outer wall of the nasal irrigation cap 31, and flow to the collection cavity 1012 through the drain port 310 and the receiving cavity 301 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 1012 through the drain port 310 and the receiving cavity 301, the liquid storage tank 309 can serve as a temporary storage area to accommodate this additional used cleaning fluid. This avoids the risk of spillage or backflow of cleaning solution after use, ensuring the cleanliness and proper functioning of the nasal irrigator 100.
