Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a body washer that cleans body orifices using a jet stream of a gas-liquid mixture.

Conventionally, cleaning devices for cleaning body openings such as the oral cavity, eye openings, and anus have used a jetting nozzle that forms a jet of cleaning liquid such as water or hot water and obtains a cleaning effect with the jetted liquid. ing. However, rather than cleaning by jetting only water or hot water from a nozzle, cleaning by mixing air bubbles into the liquid is more effective in removing foreign objects and dirt due to the behavior of the air bubbles, and removing and scattering foreign objects and dirt due to the bursting of air bubbles. The cleaning effect can be further improved. Further, when the gas-liquid mixed flow collides with the object to be cleaned in the body opening, the impact is softer than when only water is present, and there are fewer water droplets scattered. Furthermore, it is an object of the present invention to provide a body washer that can be used in any posture and ejects a gas-liquid mixed flow by taking advantage of the advantages of a gas-liquid mixed flow rather than using only liquid.

That is, according to the present invention, the water guide rod has a jetting end for jetting a gas-liquid mixed flow for cleaning body openings at the tip thereof, and the pressurized liquid is delivered to the jetting end via a delivery pipe. In the device, the ejection end includes an ejection nozzle for the pressurized liquid, an air suction hole for sucking external air using a nozzle effect generated by the ejection liquid from the ejection nozzle, and a A body washer is provided that is characterized by being provided with a gas-liquid mixing chamber and a jetting section for a gas-liquid mixed flow. Further, when the body washer according to the present invention is directed upward to eject a gas-liquid mixed flow, a liquid prevention disc is provided to prevent falling liquid from being sucked from the air suction hole and interfering with air suction. Another feature of the present invention is that a liquid prevention cylinder is formed around the jet nozzle.

Next, the present invention will be explained in more detail with reference to embodiments shown in the accompanying drawings. FIG. 1 shows the overall structure of a body washing device according to the present invention. In the cleaning device, 1 is a liquid container body, 2 is a power plug, 3 is a power switch, 4 is a power lamp, 5 is an appropriate temperature indicator lamp, 6 is a container lid, 7 is a gas-liquid mixed flow jetting device,
8 is a nozzle rod for water introduction, 9 is a handle, 10 is an on/off button for ejection, 11 is a flexible water supply pipe, and S is a liquid supply pipe. Although not shown, various parts such as a liquid storage tank, a liquid pressure pump, and a heater are housed inside the water capacity main body 1.

FIG. 2 shows a cross section of the gas-liquid mixed flow jetting device 7, in which 12 is a nozzle disk equipped with a plurality of nozzle holes;
13 is a current plate with many small holes, H is an outer cylinder 14
A gas-liquid mixing chamber M in the outer cylinder 14 that surrounds the nozzle disk 12 with a plurality of air suction holes provided around the nozzle disk 12.
It communicates with the outside air. Further, 15 is a spacer for pressing down the nozzle disk 12 from below, and a lid 16
It is fixed by. Note that the lid 16 is attached to the outer cylinder 1.
It is attached to the lower end of 4 by screwing or the like. 1
A water supply path 7 is formed inside the water guide rod 8 and guides the liquid supplied under pressure by the pump in the liquid container body 1 to the nozzle plate 12. The liquid ejected from the plurality of nozzle holes of the nozzle plate 12 in the same direction (upward in the figure) becomes hydrodynamically high-speed and low-pressure, thereby drawing external air A from the air suction hole H into the gas-liquid mixing chamber M.
The gas is suctioned into bubbles, and the gas-liquid mixed flow S, which is further divided and homogenized, is ejected from the pores of the current plate 13 to the outside through the current plate 13. The disk 18 and the cylinder 19 are a liquid prevention disk and a liquid prevention cylinder that are provided to prevent the falling liquid from being sucked into the air suction hole H when the gas-liquid mixed flow is ejected upward. . It is desirable that the end of the liquid prevention cylinder has a length that covers the air suction hole H. Note that liquid is force-fed to the gas-liquid mixed flow jetting device 7 when the water guiding nozzle rod 8 is turned on (opened) using the on/off button 10 described above.

As described above, according to the present invention, air is sucked from the outside air by the nozzle effect of the liquid passing through the nozzle disk, and a gas-liquid mixed flow is formed, which is then passed through the rectifier plate to form a jetted flow of the gas-liquid mixture. A body washing device having a simple structure can be formed, and an excellent washing effect can be obtained. It goes without saying that this cleaning device is intended to be applied not only to the human body but also to pet animals and the like.
