Description

Technical Field

[0001] This invention relates to the field of nasal irrigator technology, and more particularly to a nasal irrigator nozzle structure and a nasal irrigator. Background Technology

[0002] A nasal irrigator is a tool used to clean the nasal cavity. It typically uses pressure to deliver saline solution into the nostrils, flowing through the nasal vestibule (the part exposed outside the head), sinuses, and nasal passages, bypassing the nasopharynx, and exiting either from one nostril or through the mouth. Through this pathway, the saline solution's own bactericidal properties and the force of the water flow expel accumulated pathogens and impurities from the nasal cavity, thereby restoring the nasal cavity's normal physiological environment and self-detoxification function, thus protecting the nasal cavity. Existing technologies disclose various nasal irrigators, such as those shown in patents CN209695794U, CN107822863A, and CN102462606A. Without exception, these all spray the saline solution from the nozzle as a water jet, which is insufficient for quickly and effectively cleaning the nasal cavity. Summary of the Invention

[0003] Based on the above, the purpose of this invention is to provide a nasal irrigator nozzle structure and a nasal irrigator, in which saline solution is sprayed out in a spiral shape, which can quickly clean the dirt in the nasal cavity.

[0004] To achieve the above objectives, the present invention adopts the following technical solution:

[0005] On the one hand, a nasal irrigator nozzle structure is provided, comprising:

[0006] The nozzle has an inlet and an outlet, as well as a cavity connecting the inlet and the outlet, and a rotating chamber is provided in the cavity near the outlet.

[0007] A rotator is disposed within the rotating cavity;

[0008] Inside the rotating chamber, the rotator is impacted by saline solution to rotate and guides the saline solution in a spiral motion, so that the saline solution is ejected from the outlet in a spiral shape.

[0009] Furthermore, the rotor includes a rotor body, the side of which is provided with at least two sets of guide channels at intervals, and the top of which is provided with a spiral groove, the guide channels communicating with the spiral groove.

[0010] Furthermore, the guide channel includes a first guide sidewall, a second guide sidewall, and a guide bottom wall, with one side of the first guide sidewall connected to one side of the guide bottom wall, and the other side of the guide bottom wall connected to one side of the second guide sidewall.

[0011] Furthermore, the spiral groove includes a first spiral sidewall, a second spiral sidewall, and a spiral bottom wall. One side of the first spiral sidewall is connected to one side of the spiral bottom wall, and the other side of the spiral bottom wall is connected to one side of the second spiral sidewall. The flow-guiding bottom wall is connected to the spiral bottom wall, the first flow-guiding sidewall is connected to the first spiral sidewall, and the second flow-guiding sidewall is connected to the second spiral sidewall.

[0012] Furthermore, both the first spiral sidewall and the second spiral sidewall include a first straight sidewall, an arcuate sidewall, and a second straight sidewall, wherein the first straight sidewall is connected to the arcuate sidewall, and the arcuate sidewall is connected to the second straight sidewall;

[0013] The top of the first flow guide sidewall is connected to the first straight sidewall, and the top of the second flow guide sidewall is connected to the second straight sidewall.

[0014] Furthermore, the angle α between the first guide sidewall and the guide bottom wall is 30° to 60°.

[0015] Furthermore, the angle γ between the second guide sidewall and the guide bottom wall is 120° to 150°.

[0016] Furthermore, a guide column is embedded in the inner wall of the pipe near the outlet, and a water passage hole is provided in the center of the guide column. The cavity between the guide column and the outlet is a rotating cavity.

[0017] Furthermore, the nozzle is bent near the water outlet.

[0018] On the other hand, a nasal irrigator is provided, including the nasal irrigator nozzle structure described above.

[0019] The beneficial effects of this invention are as follows:

[0020] This invention provides a nasal irrigator nozzle structure and a nasal irrigator. The principle is as follows: the main unit of the nasal irrigator drives saline solution to enter the tube through the inlet. The saline solution then impacts and enters the rotating chamber. Inside the rotating chamber, the saline solution impacts a rotator, causing it to rotate and forming a spiral water flow within the chamber. This spiral water flow is then sprayed out from the outlet, where it converges at a single point outside the nozzle. The spiral water flows collide and refract in various directions. Compared to existing technologies, this multi-directional refraction of the water flow allows for effective impact cleaning of various areas within the nasal cavity, quickly removing dirt and impurities.

Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments.

[0035] Example 1

[0036] like Figures 1 to 7As shown, this embodiment of the invention provides a nasal irrigator nozzle structure, including a nozzle 1 with an inlet 2 and an outlet 3, and a cavity 4 connecting the inlet 2 and the outlet 3. Preferably, the internal cross-section of the cavity 4 is circular, and a rotating cavity 5 is provided in the cavity 4 near the outlet 3. A rotator 6 is disposed in the rotating cavity 5. In the rotating cavity 5, the rotator 6 is impacted by saline solution to rotate and guide the saline solution to move in a spiral motion. The saline solution is sprayed out from the outlet 3 in a spiral shape. It should be noted that the size of the rotator 6 is smaller than the size of the rotating cavity 5 to ensure that the rotator 6 rotates around the central axis 8 in the rotating cavity 5.

[0037] Specifically, in this embodiment of the invention, the main unit of the nasal irrigator drives saline solution to enter the cavity 4 from the inlet 2. The saline solution then impacts and enters the rotating cavity 5. Inside the rotating cavity 5, the saline solution impacts the rotor 6, causing it to rotate. This causes the saline solution to form a spiral flow within the rotating cavity 5 and then spray out from the outlet 3. Figure 7 As shown, the spiral water flow converges at a point outside the nozzle 1. After the spiral water flow collides with each other, it is refracted in all directions. Compared with the existing technology, the water flow is refracted in all directions, which can impact and clean various parts of the nasal cavity, and can quickly clean the dirt in the nasal cavity.

[0038] As a preferred embodiment of the present invention, such as Figure 4 and 5 As shown, the rotor 6 includes a rotor body 61. At least two sets of guide channels 62 are spaced apart on the side of the rotor body 61. In this embodiment of the invention, two sets of guide channels 62 are provided, symmetrically spaced on the side of the rotor body 61. A spiral groove 63 is provided on the top of the rotor body 61, and the guide channels 62 communicate with the spiral groove 63. Specifically, in this embodiment of the invention, after the water flow impacts and enters the rotating cavity 5, the water flow impacts the bottom of the rotor 6. Then, the water flow is guided from the guide channels 62 on the side of the rotor 6 into the spiral groove 63. Within the spiral groove 63, the water flow forms a spiral water flow. The rotor 6 rotates synchronously, and under the double spiral, the spiral water flow is ejected from the outlet 3.

[0039] As a preferred embodiment of the present invention, such as Figure 4 and Figure 5As shown, the flow channel 62 includes a first flow-guiding sidewall 621, a second flow-guiding sidewall 622, and a flow-guiding bottom wall 623. One side of the first flow-guiding sidewall 621 is connected to one side of the flow-guiding bottom wall 623, and the other side of the flow-guiding bottom wall 623 is connected to one side of the second flow-guiding sidewall 622. Further, the spiral groove 63 includes a first spiral sidewall 631, a second spiral sidewall 632, and a spiral bottom wall 633. One side of the first spiral sidewall 631 is connected to one side of the spiral bottom wall 633, and the other side of the spiral bottom wall 633 is connected to one side of the second spiral sidewall 632. The flow-guiding bottom wall 623 is connected to the spiral bottom wall 633. The first flow-guiding sidewall 621 is connected to the first spiral sidewall 631, and the second flow-guiding sidewall 622 is connected to the second spiral sidewall 632. Furthermore, both the first spiral sidewall 631 and the second spiral sidewall 632 include a first straight sidewall 6321, an arcuate sidewall 6322, and a second straight sidewall 6323. The first straight sidewall 6321 is connected to the arcuate sidewall 6322, and the arcuate sidewall 6322 is connected to the second straight sidewall 6323. The top of the first flow guiding sidewall 621 is connected to the first straight sidewall 6321, and the top of the second flow guiding sidewall 622 is connected to the second straight sidewall 6323. Specifically, in this embodiment of the invention, the arc-shaped sidewall 6322 curves toward the center of the spiral groove 63. The water flows from the bottom of the guide channel 62 to the top of the guide channel 62, and then enters the spiral groove 63. When the water flows through the middle of the first straight sidewall 6321 of the first spiral sidewall 631 and the second straight sidewall 6323 of the second spiral sidewall 632, the water flow channel gradually narrows. There will be a squeezing effect between the water flows, which can increase the flow velocity of the water flow and enable the rotor 6 to rotate. Then the water flow will generate a spiral water flow along the arc-shaped sidewall 6322. At the same time, the rotation speed of the rotor 6 will increase. Finally, the spiral water flow is ejected from the outlet 3.

[0040] As a preferred embodiment of the present invention, such as Figure 6 As shown, the angle α between the first guide sidewall 621 and the guide bottom wall 623 is 30° to 60°. Further, the angle γ between the second guide sidewall 622 and the guide bottom wall 623 is 120° to 150°. Specifically, by setting the angle α between the first guide sidewall 621 and the guide bottom wall 623 and the angle γ between the second guide sidewall 622 and the guide bottom wall 623, when water enters the guide channel, the water will push the rotor 6 to rotate in the direction of the first guide sidewall 621, thus causing the rotor 6 to rotate and generate a spiral water flow.

[0041] As a preferred embodiment of the present invention, such as Figures 1 to 3As shown, a guide column 7 is embedded in the inner wall of the pipe cavity 4 near the outlet 3. A water passage hole 71 is provided in the center of the guide column 7. The cavity between the guide column 7 and the outlet 3 is a rotating cavity 5. Specifically, the inner diameter of the cavity 4 gradually decreases from the inlet 2 to the guide column 7. When installing the rotor 6 and the guide column 7, the rotor 6 is first placed into the cavity 4 from the inlet 2. Then, the nozzle 1 is reversed, and the rotor 6 falls into the cavity 4 near the inlet 2 under the action of gravity. Then, the guide column 7 is placed into the cavity 4 from the inlet 2. As the inner diameter of the cavity 4 continuously decreases, the guide column 7 will be stuck near the outlet 3. Then, the guide column 7 is squeezed by a tool to embed it into the cavity 4. The cavity between the guide column 7 and the outlet 3 is the rotating cavity 5, which facilitates the installation of the rotor 6. At the same time, the water passage hole 71 of the guide column 7 is set at the center of the guide column 7. The water passage hole 71 plays the role of guiding the water flow and guiding the water flow to impact the center of the bottom of the rotor 6.

[0042] As a preferred embodiment of the present invention, such as Figures 1 to 3 As shown, in order to adapt to the ergonomics of the nose position on the human face, the nozzle 1 is bent near the water outlet 3.
