Example

[0030] Reference Figure 1-Figure 7 As shown, the utility model is a waste liquid reflux collection type nasal cleaning device, comprising:

[0031] A waste liquid bin mechanism, comprising: a bin body 1, a water channel cover 2 and a cover body 3 respectively covering both sides of the waste liquid bin, wherein the bin body 1, the water channel cover 2 and the cover body 3 enclose a chamber for containing waste liquid, and the water channel cover 2 and the cover body 3 are respectively provided with a first water channel 12 and a second channel 4 communicating with the chamber, and in order to improve the sealing performance, a sealing element such as a sealing gasket or a sealing ring can be provided at the connection between the water channel cover 2 and the cover body 3 and the bin body 1;

[0032] A spray head assembly 5, which is disposed in the chamber, has a first end connected to the first water channel 12, and a second end extending into the second channel 4, and the second channel 4 is used to extend into the nasal cavity;

[0033] The reflux structure includes: a first reflux channel 15 disposed between the second channel 4 and the cover body 3 , and a second reflux channel 16 formed between the second channel 4 and the spray head assembly 5 .

[0034] The utility model discloses a waste liquid reflux collection type nasal cleaning device, which contains the refluxed waste liquid through the waste liquid bin and provides structural strength and corrosion resistance. The water channel cover 2 and the cover body 3 are respectively arranged on both sides of the waste liquid bin mechanism, which are used to close the bin body 1 to form a containing chamber and provide corresponding water channel connection and protection. The water channel cover 2 is provided with a first water channel 12 connected to the chamber and used to connect to an external cleaning liquid supply system. The spray head assembly 5 is used to spray atomized cleaning liquid to rinse the nasal cavity or spray atomized liquid. The cover body 3 is provided with a second channel 4 connected to the chamber. , used to return the waste liquid after cleaning to the chamber, the refluxed liquid returns to the chamber from the outside of the second channel 4 through the first reflux channel 15. When the waste liquid returns, the second reflux channel 16 is the nasal channel, and the waste liquid in the nasal cavity directly enters the chamber through the second reflux channel 16. The waste liquid overflowing from the gap between the nostril and the second channel 4 flows back into the chamber along the first reflux channel 15 from between the cover body 3 and the second channel 4, so that the cleaning liquid can completely return to the chamber in the warehouse body 1, avoiding the outflow of waste liquid, improving the cleanliness when using the nasal washer and providing a certain recovery value.

[0035] See also Figure 3As shown, the spray head assembly 5 includes: a spray head 51 having one end sealedly connected to the first water channel 12 and a second end extending into the second channel 4, and a pump core 52 arranged in the spray head 51. The second water channel 10 and the first water channel 12 are sealed and connected, and the spray head 51 is connected to the second water channel 10. The pump core 52 is used to disperse the liquid passing through the spray head 51 into water mist. The fan-shaped surface opening angle range of the water mist is between 30 and 120°. The pump core 52 will evenly divert the liquid in the water channel to the swirl groove. At this time, the liquid will form a liquid film, which will be dispersed through the vortex chamber to finally form water mist for spraying. In some embodiments, the spray head assembly 5 can also be configured to adopt a structure with multiple fine spray holes to achieve the effect of dispersing the liquid into water mist.

[0036] The number of the spray head assembly 5, the reflux structure, the first water channel 12 and the second channel 4 is two groups, and the two groups of the spray head assembly 5 are arranged at intervals and relatively inclined, so as to adapt to two nostrils of the human body.

[0037] Continue to see Figure 1 , Figure 5-Figure 7 As shown, the cover body 3 is provided with a stop wall 14 between the two groups of spray head assemblies, and the stop wall 14 and the top wall of the cover body 3 enclose a first guide groove 6, the bottom wall of the first guide groove 6 is arc-shaped, and a first through hole 7 connected to the chamber is opened at the low point of the arc-shaped bottom wall of the first guide groove 6, the stop wall 14 is used to enclose the first guide groove 6 with the outer wall of the second channel 4, the first guide groove 6 is used to collect and guide the flow of the cleaning liquid, and its arc-shaped bottom wall design can make the cleaning liquid flow downward in a concentrated manner, improve the recovery effect and avoid residue, and the first through hole 7 is used to connect the chamber and the first guide groove 6, so that the cleaning liquid can smoothly enter the chamber.

[0038] See also Figure 1 , Figure 5-Figure 7 As shown, a second guide groove 8 is provided on the side away from the two groups of the second channels 4, and the bottom wall of the second guide groove 8 is arc-shaped. A second through hole 9 connected to the chamber is opened at the low point of the arc-shaped bottom wall of the second guide groove 8. The first guide groove 6, the second guide groove 8, the first through hole 7 and the second through hole 9 together constitute a first reflux channel 15. Similar to the first guide groove 6, the arc-shaped bottom wall design of the second guide groove 8 can make the cleaning liquid flow downward in a concentrated manner, improve the recovery effect and avoid residue, and is used for the two groups of spray head assemblies 5 to be arranged at intervals, so that the outer shell is constructed into an ellipse to accommodate the two groups of spray head assemblies 5 in a smaller size, and the two groups of spray head assemblies 5 are respectively arranged at the two focal positions of the ellipse, the second guide groove 8 is arranged on the short arc side at both ends of the ellipse, and the first guide groove 6 is arranged on the long arc side of the ellipse.

[0039] See also Figure 1As shown, the height of the second guide groove 8 is greater than that of the first guide groove 6, and the second through hole 9 is arranged on one side of the second guide groove 8 close to the first guide groove 6. Since the second channel 4 needs to protrude from the cover body 3 and extend to fit the nostril, and the second guide groove 8 is arranged in the short arc part, the second channel 4 is close to the side wall of the cover body 3 at both ends of the major axis of the ellipse, resulting in the waste liquid easily flowing through the outer wall of the cover body 3. By arranging the second guide groove 8 on the side wall of the second channel 4, the waste liquid on both sides of the length direction of the cover body 3 is guided to the second guide groove 8, and the second guide groove 8 is tilted downward toward the center part of the cover body 3 to prevent the waste liquid in the second guide groove 8 from flowing out of the cover body 3. When the waste liquid flow rate is too large, the waste liquid will overflow from the second guide groove 8 into the first guide groove 6. The volume of the first guide groove 6 is much larger than that of the second guide groove 8. Correspondingly, the size of the first through hole 7 is also much larger than that of the second through hole 9, which can prevent the first guide groove 6 from overflowing and increase the waste liquid recovery flow rate.

[0040] See also Figure 2 As shown, the second channel 4 includes: a tapered portion 41 that narrows upward, and an extension portion 42 that is arranged around the end of the tapered portion 41, the extension portion 42 is used to extend into the nasal cavity, and the outer surface of the tapered portion 41 is a concave arc surface, so that it can gradually adapt to the shape of the nasal cavity. The extension portion 42 is provided with rounded corners, and the extension portion 42 can be made of soft materials, such as silicone, to improve the comfort of the nasal cavity and protect the nasal cavity.

[0041] See also Figure 4 , Figure 5 As shown, the inner diameter of the extension portion 42 is larger than the outer diameter of the end of the spray head assembly 5, and an annular gap 13 is provided between the end of the spray head assembly 5 and the extension portion 42, and the annular gap 13 constitutes a second reflux channel 16, through which the waste liquid refluxed in the nasal cavity enters the chamber.

[0042] See also Figure 2 , Figure 7 As shown, the water channel cover 2 is provided with a third through hole 11, and the third through hole 11 is respectively connected to the two groups of the first water channels 12. The cleaning liquid enters the first water channel 12 from the third through hole 11. Through the connecting effect of the two groups of first water channels 12, the fluid is diverted between the two groups of first water channels 12. The specific working process is as follows: the fluid enters from the third through hole 11 and flows into the two groups of first water channels 12 respectively to the two groups of spray heads 51 and the pump core 52; the fluid is atomized in the pump core 52 and sprayed out from the spray head 51. The first water channel 12 and the spray head assembly 5 are sealed and connected to prevent waste liquid from entering the spray head assembly 5 to participate in atomization.

[0043] See also Figure 4As shown, the angle α between the central axis of the spray head assembly 5 and the central axis of the bin body 1 is 5° to 20°. In the present embodiment, α is 10°, 12°, or 13°, and can be compatible with the nasal angles of all groups of people as needed. For example, for people with narrower nasal cavities, a smaller angle, such as 7°, can be selected to ensure that the spray head can penetrate deep into the nasal cavity for cleaning; and for people with wider nasal cavities, a larger angle, such as 15°, can be selected to avoid collision between the spray head and the inner wall of the nasal cavity.

[0044] Obviously, the above embodiments are merely examples for clear explanation and are not intended to limit the implementation methods. For ordinary technicians in the relevant field, other different forms of changes or modifications can be made based on the above description. It is not necessary and impossible to list all the implementation methods here. The obvious changes or modifications derived from them are still within the protection scope of the invention of the utility model.
