JPH02144432A - Hollow jet water nozzle for cleaning anus - Google Patents

Abstract

PURPOSE:To prevent water from being splashed by a method wherein hollow- state water is jetted from a jet port, and wherein air in an internal space is sucked in with suction due to the flow of feed water, and wherein water and air are separated from each other on the down stream of the feed water, and water only is jetted again from a nozzle. CONSTITUTION:When water fed from a feed water port 9 passes a throttling section 5, then a speed is heightened, and static pressure is lowered, and air is sucked in from the periphery. After that, the air is mixed with water through an air suction port 6, and is jetted almost in the direction of the tangent line of a cylindrical section 7. After that, while the mixture of the water and air is turned around the cylindrical section 7, the mixture is pushed to the peripheral side of the cylinder by a centrifugal force, and the air is concentrated on a central section and is discharged to an external section from an air hole 8. Besides, the water is turned outside the throttling section 5 and an air communicating section 13 and reaches a ring-shaped jet port 2, and is jetted to the external section from the jet port 2.

った。There have been devices for cleaning the anus and other areas with water jets, but the structure of the jet nozzle part is as shown in Figure 7.
The spout 2 of the nozzle 1 was generally circular or rectangular, and the cross section of the water 3 jetted toward the anus was also circular or rectangular. Therefore, when the water is sprayed and flies a certain distance, it becomes spherical water 4, which intermittently hits the anal region. As a result, people who have a disease in the anal region may feel uncomfortable and dislike the device, or water droplets may scatter around the anal region, making it uncomfortable to use.

〔発明が解決しようとする課題〕[Problem to be solved by the invention]

本発明は、前項に述べた欠点すなわち、痛さと飛沫の飛
散の２点を解決しようとするものである。The present invention aims to solve the two drawbacks mentioned in the previous section, namely, pain and the scattering of droplets.

せることをもって行なおうとするものである。In order to solve the above drawbacks, the present invention makes the shape of the jet 0.2 ring-shaped, the shape of the jetted water is rugby ball-shaped, and the internal space volume of the rugby ball-shaped water film is increased or decreased. It is something to do.

ル状となる。(Function) As shown in Fig. 3, water is ejected from the ring-shaped spout 2, and at the same time, the air inlet 6 provided in the area surrounded by the spout 2
When air is sucked in, the water jet 3 flies out in a cylindrical shape, and then first becomes constricted due to surface tension, and as shown in Figure 3a, it becomes completely closed in the shape of a rugby ball, as shown in Figure 3a.

のである。During this time, the air inside the rugby ball-shaped water film flows through the air intake port 6.
As it continues to be discharged to the outside through the air, a small water film forms as shown in Fig. 3 (c), and eventually the water is sucked into the air intake port 6 and the air discharge stops, returning to the state shown in Fig. 3 (a). Return to Cleaning is performed by repeating this operation.

リング状の噴出口２と連通ずるようにした構成である。FIG. 1 is a partially cutaway perspective view of one embodiment, and FIG. 2 is a sectional view showing its operating state. As shown in these figures, a throttle part 5 is provided on the downstream side of the water supply port 9 so that the periphery of the throttle part 5 communicates with the air intake port 6, and an air vent hole is provided in the center on the downstream side of the throttle part 5. 8 are connected to each other, and the outlet of the cylindrical portion 7 is communicated with a ring-shaped ejection port 2 provided around the air intake port 6.

また空気吸入口６の周囲は逆円錐状となっておりリング

出する。The flow conditions due to these configurations will be explained with reference to FIG. When the water sent from the water supply port 9 passes through the constriction part 5, its speed increases, so that the static pressure decreases and air is sucked in from the surrounding area. Therefore, the air passes through the air intake port 6, mixes with water, and is injected approximately tangentially to the cylindrical portion 7. That water-
While the air mixture rotates around the cylindrical portion 7, centrifugal force forces the water to the outside of the cylinder, and as a result, the air gathers in the center and is discharged to the outside through the air vent hole 8. - The powered water goes around the outside of the above-mentioned constriction part 5 and air communication part 13, reaches the ring-shaped spout 2, and is spouted outward from there.

As a precaution, as shown in Fig. 5, the nozzle section is normally installed so as to be inclined downward at an angle of δ with respect to the horizontal, so that the water droplets after hitting the anus will not reach the air intake port 6. It never gets blocked.
