Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a nozzle for a cleaning device that is attached to a toilet bowl and sprays water onto private parts such as the anus, which has been improved so that it has a high cleaning effect and is comfortable to use.

Conventionally, nozzles for this type of cleaning device have a structure that only sprays water in a fixed direction, so the spray does not necessarily hit the appropriate place, and the expected cleaning effect cannot be achieved unless the user moves the position himself. In addition, there are inconveniences such as the user not being able to obtain the desired results, or the water being concentrated in a certain location in a sensitive private area, causing the user to feel pain.

The present invention has been made to address these conventional drawbacks, and will be explained in detail below based on embodiments shown in the drawings. FIG. 1 is a schematic explanatory diagram of a cleaning device according to the present invention, and 1 is a toilet bowl. 2 is the cleaning device itself. Reference numeral 3 denotes a nozzle extending from the cleaning device 2 through a cylinder 4 and facing into the toilet bowl 1. Figures 2 to 6 show the structure of this nozzle 3, which is formed by bringing a nozzle body 3' into contact with a guide body 3'' formed by joining a channel plate 13 and an outer plate 14. , the main body 3 and the guide body 3
Water channels a-b are carved in the pattern shown in FIGS. 2 and 3, respectively. The groove a of the nozzle body 3' has a water inlet passage 6 that guides water from the nozzle water inlet 5, a nozzle part 7 that spouts water from the inlet passage 6, and a groove a with its lower end facing the nozzle part 7 upward. A fountain 8 that expands in a tapered manner in the left and right directions, that is, the front and back directions relative to the toilet bowl, and a capacity 10 that has guide passages 9 and 9' that are substantially perpendicular to the nozzle portion 7, and is arranged on the left and right sides of the fountain 8, respectively.・1d,! : Yori is formed.

On the other hand, signal paths 11 and 11' are formed in the groove of the guide body 3'', which alternately connect the volumes 10 and 10' with the left and right sides of the water fountain 8. Therefore, the nozzle 3 The water guided inside is ejected as high-pressure water from the nozzle section 7 via the water conduit 6, but this fountain flow is caused by the vortex generated against the side wall of the fountain port 8 and the guide channel 9 facing the nozzle section 7.
- The pressure becomes unstable due to the influence of air and water introduced from 9' by the injection action, and it adheres to either the left or right wall of the spout 8 and becomes temporarily stable. Once the water is stabilized on some wall surface, for example the left wall surface, the water fountain flow will flow along the taper angle of this left wall surface. The inside of the sealed capacity 10 on the right side is made negative pressure by injection from the guide path 9. On the other hand, on the capacity 10 side, external pressure can be introduced from the signal path 11 to the injection from the guide path 9, so the pressure difference between the left and right sides increases at the jet port 8, and the jet flow loses stability again and flows to the right side of the negative pressure side. It is attracted and automatically switches and attaches. In this way, the fountain flow from the nozzle is automatically switched to land on the left and right side walls f1, and therefore, this fountain performs reciprocating motion within a range extending the taper angle of the left and right wall surfaces. The cycle of this reciprocating motion can be adjusted to a certain extent by changing the capacity 10. − is desirable. Further, experimental data has been obtained that the taper angle between the side walls of the water fountain 8 should be within the range of 5° to 30° in order to perform the above operation. This fountain flow operates in the same way as an oscillation circuit in a pure fluid element, and these principles can be explained in, for example, "Introduction to Pure Fluid Elements" (
It is introduced in related literature such as Mekkan Kogyo Shinbunsha).

5 and 6 are cross-sectional views of the guide body 3'' at the positions of the openings 12 and 12' of the signal paths 11 and 11' relative to the water fountain 8, respectively.
Notch grooves 15 and 15' are formed facing downward, respectively, and signal paths 11 and 1 are formed using these grooves 15 and 15' as guides.
Consideration has been given to making it easy to introduce water into 1'. This means that water from this fountain flow is actively introduced into the signal path from the opening on the side where the fountain flow is attached, and water is supplied from the guide path to the side where the water flow is not attached, making it easier to switch over the attached water. It is intended to serve as a priming water.

In the present invention configured as described above, the water fountain from the nozzle 3 continuously reciprocates along the taper angle of the spout 8 in the front and rear directions with respect to the toilet bowl.

Since the present invention is configured such that the direction of the water fountain from the nozzle is continuously moved back and forth at least in the front-rear direction of the toilet bowl, the cleaning range of the water fountain can be widened, and therefore, the tolerance for the seating position of the user can be increased. Can be made wider. In addition, the water flow intermittently hits the dirt as a reciprocating flow, which promotes the pre-exfoliation effect from the skin and improves the cleaning effect. Furthermore, compared to the conventional method, the water flow is not focused on only one area, so the user can use it comfortably without feeling discomfort such as pain, and can expect a pine surge effect due to the reciprocating flow. In addition, this nozzle has a structure in which it oscillates in a pure fluid manner and does not require any mechanical operation, making it easy to configure and cost-effective.It is also extremely durable and can be used semi-permanently. .
