Abstract

A cleaning water jetting device 40 formed so as to rotate a nozzle by a fluid pressure and capable of reducing the size of the drive part of a pump for feeding fluid to a chamber and an operation cost, comprising an upper side through-hole 6A recessedly formed in edge shape provided in the ceiling of the chamber 2 and a bottomed concave part 43 formed in round hole shape provided in the bottom surface thereof, wherein the nozzle 4 is installed by inserting a reduced diameter part 7 on a nozzle tip side at the nozzle tip side into the upper side through-hole 6A and the bottom portion 44 into the concave part 43, and kept in such a state in the upper side through-hole 6A as to face a cleaning fluid jetting port 5 toward the outside of the through-hole, to be rotated, and to allow the position thereof to be changed in a nozzle axis O direction, and can be revolved around the center axis thereof in the tilted attitude relative to the center axis P of the upper side through-hole 6A.

Description

technical field [0001] The invention relates to a fluid ejection device, which comprises a cavity for containing fluid, and ejects the accommodated fluid from a fluid ejection port. Background technique [0002] As an example of this type of fluid ejection device, topical cleaning devices for cleaning a part of the human body, such as the anus, are well known. When such a local cleaning device is used, when the cleaning water is sprayed from a single fluid ejection port to a part of the human body, it is generally desirable that the water contact area of ​​the sprayed cleaning water be larger. [0003] In order to achieve such a requirement, two methods can generally be used, one method is to rotate the nozzle arm with the nozzle in a circular arc trajectory (nozzle arm rotation method), and the other is to use the nozzle arm with the nozzle inside A method of internally driving the nozzle itself (nozzle rotation method). However, with the for...
