[0026] The present invention will be further described below with reference to the accompanying drawings and specific embodiments so that those skilled in the art can better understand the present invention and implement it. However, the embodiments are not intended to limit the present invention.

[0027] Example

[0028] Reference Figure 1-Figure 5 As shown, the utility model is a reflux single-nostril nasal irrigator, which is characterized by comprising:

[0029] The main body 1 is provided with a pump 9. A cleaning head 2 and a liquid clearing tank 12 are respectively provided on both sides of the main body 1. The relative positions of the cleaning head 2 and the liquid clearing tank 12 can be upper and lower sides, or lower and upper sides. The input end and output end of the pump 9 are respectively connected to the liquid clearing tank 12 and the cleaning head 2;

[0030] The cleaning head 2 has a waste liquid tank, and the cleaning head 2 includes a first annular wall 5, a first wall body 4 and a second annular wall 14 connected in sequence. A first groove body 7 is formed between the first annular wall 5 and the first wall body 4. The first groove body 7 is provided with a first through hole 8 for connecting to the waste liquid tank. A second through hole 15 for communicating with the waste liquid tank is provided between the first wall body 4 and the second annular wall 14. The second annular wall 14 is provided with a spray port 13.

[0031] The present invention discloses a single-nostril nasal irrigator with reflux. The second annular wall 14 is inserted into the nostril to be cleaned. Pump 9 is activated to draw cleaning fluid from the liquid reservoir 12 and deliver it to the cleaning head 2 through the output port. After entering the cleaning head 2, the cleaning fluid is sprayed from the spray port 13 through the spray assembly 3 in the form of tiny droplets. These droplets are then delivered to the nasal cavity by airflow, thereby cleaning the nasal cavity. The waste liquid generated during the cleaning process flows back to the waste liquid bin through three reflux channels. The first reflux channel includes a first groove body 7 between the first annular wall 5 and the second wall body, which enters the waste liquid bin through the second through hole 15; the second reflux channel includes a first through hole 8 between the first wall body 4 and the first annular wall 5. The waste liquid overflowing from the second through hole 15 is blocked downward by the first annular wall 5, and is collected in the first groove body 7 and introduced into the waste liquid bin through the first through hole 8; the third reflux channel is a spray port 13. While the cleaning liquid is cleaning the nasal cavity, the waste liquid can be collected in the waste liquid bin in time, realizing the recycling of the cleaning liquid and the timely treatment of the waste liquid, thereby improving the efficiency and effect of nasal cleaning.

[0032] The first trough body 7 continuously surrounds the first wall body 4, and the number of the first through holes 8 is one or more. The first through holes 8 are opened in the bottom wall of the first trough body 7. The first trough body 7 continuously surrounds the first wall body 4 to form a complete annular trough body, enclosing the spray port 13 in the middle, so that waste liquid in each direction can flow into the first trough body 7, making the collection of waste liquid more efficient and comprehensive, and helping to keep the cleaning process clean and hygienic. In this embodiment, there are two first through holes 8, and the first through holes 8 can also be four, and they are arbitrarily set on the bottom wall of the first trough body 7 at 360°, and the path of the second reflux channel will not change.

[0033] A transition top 16 is provided between the first wall 4 and the second annular wall 14. The transition top 16 has a curved transition surface. One or more second through holes 15 are provided in the transition top 16, surrounding the spray port. Waste liquid generated flows along the inner wall of the nasal cavity toward the spray port 13 and the outer wall of the cleaning head 2. When waste liquid flows into the area between the first wall 4 and the second annular wall 14, the curved transition top 16 allows the waste liquid to flow smoothly along the curved surface. The second through holes 15 provided in the transition top 16 enable the waste liquid to be promptly collected and directed into the waste liquid storage bin.

[0034] The first annular wall 5, the first wall body 4, the transition top 16 and the second annular wall 14 are narrowed in sequence. The second annular wall 14 is used to extend into the nostril to be cleaned, and the transition top 16 is used to abut the end surface of the nostril. The second annular wall 14 is used to extend into the nostril to form a step seal to further reduce overflow. At least the second annular wall 14 and the transition top 16 are made of silicone, which improves comfort and elasticity and enhances the sealing effect.

[0035] The cleaning head 2 is provided with a spray assembly 3, which is used to output a spray from the end. The input end of the spray assembly 3 is connected to the machine, and the output end of the spray assembly 3 extends to the spray port 13 in the waste liquid tank. The pump 9 extracts and pressurizes the cleaning liquid in the liquid tank 12, and then transports the cleaning liquid to the input end of the spray assembly 3 through the connecting pipe. The spray assembly 3 is an existing spray assembly 3. After the cleaning liquid enters the spray assembly 3, it is converted into a fine spray at the micron or nanometer level and output from the end of the spray assembly 3. It is ejected from the spray port 13 along the extension path of the output end in the waste liquid tank and penetrates into the nasal cavity, effectively cleaning or treating the nasal cavity. The existence of the waste liquid tank does not affect the normal output of the spray, but also provides storage space for the waste liquid generated during the cleaning process, realizing the simultaneous cleaning and waste liquid collection.

[0036] There is a first spacing space between the end of the spray assembly 3 and the inner wall of the first annular wall 5, which is used as a space for the third reflux channel.

[0037] The end of the second through hole 15 extends to the transition top 16, and the end of the spray component 3, the transition top 16 and the first wall 4 have a second gap space. The height of the end of the spray component 3 is the first height, and the height of the opening on one side connected to the second through hole 15 and the second gap space is the second height. The first height is greater than the second height, which prevents the waste liquid in the second reflux channel from entering the spray path and avoiding external infection.

[0038] The cleaning head 2 is also covered with a cover 10, which is mounted on the cleaning head 2 and snap-fitted to the main body 1. This prevents dust and impurities from entering the cleaning head 2, ensuring the cleanliness of the cleaning head 2. The cover 10 is connected to the main body 1 by a snap-fit ​​connection, which is simple, reliable, and easy to install and remove. The snap-fit ​​connection is equipped with a corresponding snap-fit ​​and sealing structure.

[0039] The cleaning head 2 is provided with a water inlet 11. The output end of the pump 9 is connected to the water inlet. A liquid inlet pipe 6 is provided in the liquid clearing tank 12. The end of the liquid inlet pipe 6 extends to the bottom of the inner cavity of the liquid clearing tank 12 and maintains a gap with the bottom wall. The input end of the pump 9 is connected to the liquid inlet pipe 6 to ensure that when the amount of cleaning liquid in the liquid clearing tank 12 is small, the liquid inlet pipe 6 can still draw cleaning liquid. At the same time, the gap with the bottom wall can prevent the end of the liquid inlet pipe 6 from contacting sediment or impurities at the bottom of the tank, ensuring the purity of the drawn cleaning liquid. The input end of the pump 9 is connected to the liquid inlet pipe 6 via a pipeline, forming a complete cleaning liquid delivery circuit.

[0040] The main body 1 also houses a battery, which is equipped with a charging port for electrical connection to the battery. The cleaning head 2 and waste liquid reservoir are both sealed and detachably connected to the main body 1. The battery provides power to components such as the pump 9. After a period of use, when the cleaning head 2 or waste liquid reservoir needs to be cleaned, the cleaning head 2 and waste liquid reservoir can be removed from the main body 1. If the battery is low, it can be recharged through the charging port on the main body 1 to ensure continued use of the nasal rinser.

[0041] Through the above-mentioned setting, the present application also has the following technical effects: 1. The clear liquid tank 12 is arranged at the bottom of the product, and the waste liquid tank is arranged at the top of the product. This layout design can separate the clear and waste liquid tanks, completely eliminating the situation where waste liquid contaminates the cleaning liquid; it is not limited to this method, and the liquid tank layout method with the clear liquid tank at the top and the waste liquid tank at the bottom can also be used.

[0042] 2. The cleaning liquid is pumped from the liquid cleaning tank 12 into the water pump by the water pump, and then the piston in the water pump pushes the cleaning liquid to the water inlet 11 at the bottom of the flushing head. The cleaning liquid is transported to the spraying area through the water channel design of the flushing head.

[0043] The liquid will be dispersed into micron-sized droplets after spraying, and the droplets will be delivered to the nasal cavity through aerodynamics, thus achieving the cleaning effect. Figure 1 shown.

[0044] 3. The waste liquid tank is equipped with waste liquid reflux grooves, which are located in two areas. The waste liquid reflux grooves can be set arbitrarily in the area 360 degrees. The waste liquid reflux path is as follows: Figure 2 and Figure 3 shown.

[0045] 4. The flushing head assembly and the night cleaning tank adopt a quick-disassembly structure, which is convenient for cleaning the flushing head and the 12 bottles of cleaning liquid in the cleaning liquid tank.

[0046] 5. This product can meet IPX7 waterproof requirements. The buttons, electronic control components, charging port plug, and water inlet 11 connected to the flushing head are all waterproof.

[0047] Obviously, the above embodiments are merely examples for clarity of explanation and are not intended to limit the implementation methods. Those skilled in the art will appreciate that other variations or modifications based on the above descriptions are possible. It is not necessary and impossible to enumerate all implementation methods here. Obvious variations or modifications arising therefrom remain within the scope of protection of the present invention.
