  The manual type nasal irrigator described in Patent Literature 1 and the eye and nose irrigator described in Patent Literature 2 both have a configuration in which the cleaning liquid is directly applied to the nostrils, and thus cleans the nostrils. There is a disadvantage that a strong stimulus sometimes occurs. The jetting action of the cleaning liquid is extremely important, and there is a demand for a cleaning liquid that is less irritating at the time of jetting and that can efficiently wash.

  In that regard, the nasal washing device described in the nasal washing device of Patent Document 3 is easier to use than the Patent Documents 1 and 2 because the ejection pressure is adjustable. That is, the nasal washer disclosed in Patent Literature 3 switches between two types of spray, a spray shape and a straight shape, with nozzles divided vertically. Further, the nasal cavity cleaning device of Patent Document 4 is configured by a push button that is biased to one side, and a seal or a gasket formed on the push button.

  However, such a configuration of the conventional nozzle has a disadvantage that the cleaning liquid cannot be uniformly injected when the cleaning liquid is injected. That is, in the cited document 3, it is described that the nozzle is divided into upper and lower portions and the nozzle is vertically separated by a built-in spring in order to switch to the spraying type of spraying by the nozzle, and the nozzle is vertically sprayed. . However, Patent Literature 3 does not disclose a means for uniformly jetting the cleaning liquid, and does not describe a specific means for switching to a spray form by a nozzle. Therefore, in Patent Literature 3, even if it is possible to switch between two types of spray forms, a spray form and a straight form, it is not possible to uniformly spray the cleaning liquid when spraying. As a result, even if the irritation is reduced as compared to the straight injection, large water droplets or fine water droplets are ejected discontinuously and are likely to be biased injection, and it is not possible to efficiently clean the nasal cavity. .

  Therefore, the present invention has been devised to solve the above-mentioned problem, and aims to provide a nasal washing nozzle which is excellent in usability and usability by efficiently dispersing the washing liquid to efficiently clean the nasal cavity. And
