There is an inconvenience that a strong irritation occurs. The spraying action of the cleaning liquid is extremely important, and there is a demand for a cleaning liquid that is less irritating and can be cleaned efficiently.

  In that respect, the nasal wash device of Patent Document 3 is easier to use than Patent Documents 1 and 2 because the ejection pressure can be adjusted. That is, the nasal wash apparatus of patent document 3 switches between two types of spray forms, a spray form and a straight form, with the nozzle divided | segmented up and down.

  However, such a conventional nozzle configuration has a disadvantage that it cannot be uniformly sprayed when the cleaning liquid is sprayed. That is, in cited document 3, in order to switch to a spray-like spray form with a nozzle, it is described that the nozzle is divided into upper and lower parts and sprayed in a spray form by separating the nozzles up and down with a built-in spring. . However, Patent Document 3 does not disclose means for uniformly injecting the cleaning liquid, nor does it describe specific means for switching to a spray-like spray form with a nozzle. Therefore, Patent Document 3 does not disclose means for uniformly injecting a cleaning liquid when spraying in a spray form, even though it is possible to switch between two spray forms, a spray form and a straight form. As a result, even though the irritation is reduced as compared with the straight injection, large water droplets and fine water droplets are ejected discontinuously, and it tends to be an uneven injection, and there remains a problem in efficiently cleaning the inside of the nasal cavity. Is.

The cleaning liquid eccentric in flow by the regulating body is provided so as to be discharged along the spiral discharge groove 2 in the cleaning liquid injection port 1.

  The discharge groove 2 of the second means is formed by a groove 11 of a substantially screw-shaped spiral rod 10 inserted into the cleaning liquid injection port 1, and the restricting body is formed from the inlet of the cleaning liquid injection port. It is formed by a spiral rod 10 protruding into the passage.

  The restricting body in the third means is engaged with the restricting rod 4 protruding into the passage 3 from the inlet 1A of the cleaning liquid injection port 1 and is locked to the restricting rod 4 when pressed by the spray pressure of the cleaning liquid. The spherical valve 5 is provided so that any one inner surface of the inner peripheral side surface of the passage 3 is biased from the center position in the passage 3.

  In the fourth means, the spherical valve 5 of the regulating body is provided so as to prevent the backflow of the cleaning liquid from the passage 3 to the container P.

In addition, since the regulation body is formed by the spiral rod 10, it is extremely rational in terms of configuration, and, when the cleaning liquid is sprayed, large-sized grains can be ejected.

  According to the restricting body of claim 3 of the present invention, the restricting rod 4 protruding into the passage 3 and the spherical valve 5 provided so as to be biased from the center position in the passage 3 allow the cleaning liquid from the container P to enter the inlet 1A. Always regulate the flow to be eccentric. As a result, the washing liquid can always be uniformly diffused, the inside of the nasal cavity is efficiently washed, and the usability and the feeling of use are improved.

  Since the spherical valve 5 of the present invention is provided so as to prevent the backflow of the cleaning liquid from the passage 3 to the container P, the spherical valve 5 prevents the backflow to the container P when the cleaning liquid is discharged. And can be used for both. Therefore, there exists an effect which simplifies the structure of the nozzle for nasal rinse of this invention.

  According to the fifth aspect of the present invention, since the discharge groove 2 is provided on the inner side surface of the cylindrical conduit 6 and the conduit 6 is embedded in the tip of the nozzle to form the cleaning liquid injection port 1, the manufacturing process is simplified. It is possible to easily cope with changes in the diameter of the ejection port 1 and the discharge groove 2.

  As described above, according to the present invention, by uniformly diffusing the cleaning liquid, various effects such as efficient cleaning of the inside of the nasal cavity and excellent usability and usability can be achieved.

  The best mode of the present invention includes a container P for storing a nasal cavity cleaning liquid, and is provided with a nasal irrigation nozzle connected to the container P to inject the cleaning liquid. A spiral discharge groove 2 is provided on the inner surface of the cleaning liquid injection port 1 provided in the nozzle. A restricting body is provided in the passage 3 connected to the inlet 1A of the cleaning liquid injection port 1 so that the cleaning liquid from the container P becomes an eccentric flow with respect to the inlet 1A. The cleaning liquid eccentric in flow by the regulating body is provided so as to be discharged along the spiral discharge groove 2 in the cleaning liquid injection port 1. The regulation body achieves the original purpose by being formed by a substantially screw-shaped spiral rod 10 inserted into the cleaning liquid injection port 1.

  The nasal wash nozzle of the present invention is used in connection with a container P for storing a nasal cavity washing liquid, and is a nasal washing nozzle that sprays the washing liquid in a spray form. The container P is formed of, for example, a material such as soft plastic, and has a property of being restored to its original shape by the elastic force of the container P itself when the side surface of the container P is strongly compressed with fingers. A flexible pipe P1 and an air valve P2 are mounted on the top of the container P, and the nozzle of the present invention is used by being connected to the tip of the pipe P1.

  The basic configuration of the nozzle of the present invention includes a cleaning liquid injection port 1, a discharge groove 2, and a regulating body.

  The cleaning liquid ejection port 1 penetrates from the tip of the nozzle to the inside and ejects the cleaning liquid from the container P, and is provided with a discharge groove 2 along the inner surface of the cleaning liquid ejection port 1.

  The discharge groove 2 is provided in a spiral shape, and when the discharged cleaning liquid is discharged along the discharge groove 2, it diffuses in a shower shape. The discharge groove 2 shown in FIG. 2 is formed between the groove 11 of the substantially screw-shaped spiral rod 10 inserted into the cleaning liquid ejection port 1 and the inner surface of the cleaning liquid ejection port 1. When the discharge groove 2 is provided by the spiral rod 10 as described above, all of the discharged cleaning liquid passes along the discharge groove 2, and the particles of the cleaning liquid scattered in a shower-like shape are enlarged and sprayed in a uniform state. be able to.

  The regulating body regulates the cleaning liquid from the container P so as to have an eccentric flow with respect to the inlet 1A, and the regulating body shown in FIG. 2 protrudes into the passage 3 from the inlet 1A of the cleaning liquid injection port. It is formed of a spiral rod 10. According to this restricting body, the cleaning liquid is restricted by the lower end portion of the spiral rod 10 and does not flow to the central position of the cleaning liquid injection port 1, and all the cleaning liquid is discharged along the discharge groove 2. At this time, when the spherical valve 5 comes into contact with the lower end of the spiral rod 10 at the time of the cleaning liquid injection, the spherical valve 5 moves in a direction to escape from the spiral rod 10, and any one of the inner peripheral side surfaces of the passage 3 from the center position in the passage 3. One inner surface is pressed to a position biased to the trap, and the eccentric flow passes through the discharge groove 2 and is discharged in a shower shape.

  On the other hand, the regulating body shown in FIGS. 3 to 6 is composed of a pair of regulating rods 4 and a spherical valve 5 provided in parallel from the lower end of the inlet 1A. At this time, the discharge groove 2 is provided directly in the cleaning liquid injection port 1 as shown in FIGS. In addition, as shown in FIG. 6, it is also possible to provide the cleaning liquid injection port 1 by providing the discharge groove 2 on the inner surface of the cylindrical conduit 6 and embedding the conduit 6 in the tip of the nozzle. Further, the spherical valve 5 is provided so that when pressed by the spraying pressure of the cleaning liquid, the spherical valve 5 is locked to the restriction rod 4 and any one inner surface of the inner peripheral surface of the passage is biased from the center position in the passage. It has been. That is, the central portion of the cleaning liquid injection port 1 below the vertical direction is always blocked by the spherical valve 5. As a result, the cleaning liquid from the container P becomes an eccentric flow with respect to the inlet 1A.

  If the cleaning liquid is directly ejected from the central portion of the cleaning liquid jet port 1 vertically below, the cleaning liquid along the discharge groove 2 is diffused, but the cleaning liquid from the center of the cleaning liquid jet port 1 is ejected vigorously. It will be. In addition, the cleaning liquid that diffuses and the cleaning liquid that sprays in a straight line are not always ejected uniformly. In some cases, the amount that diffuses increases, and in other cases, the amount that sprays linearly increases. It becomes a stable trend.

  When the flow is made eccentric by the regulating body of the present invention, all the cleaning liquid is discharged along the spiral discharge groove 2 in the cleaning liquid injection port 1, and the cleaning liquid to be ejected is always diffused in a stable state. It is something that can be done.

  The spherical valve 5 also has a function as a check valve for preventing the backflow of the cleaning liquid from the passage 3 to the container P. That is, an air valve P2 is provided on the top of the container P, and after the cleaning liquid in the container P is discharged, air flows into the container P from the air valve P2. At this time, the spherical valve 5 serves as a check valve to close the pipe P1 and prevent the cleaning liquid remaining inside the nozzle from returning into the container P (see FIG. 2). In the illustrated example, the insert 7 and the lid 8 are formed by dividing the nozzle of the present invention vertically. The upper insert 7 is provided with a cleaning liquid injection port 1, a discharge groove 2, and a restriction rod 4. The lower lid 8 is provided with a passage 3 and a connecting pipe 9, and the spherical valve 5 is accommodated in the passage 3. The connection pipe 9 is a member connected to the pipe P1, and the spherical valve 5 seals the upper opening of the connection pipe 9 so that it can be opened and closed.
