## Abstract

In a scalp washing device a droplet preventing plate is provided positioned between a user's scalp and face, a nozzle having a single discharge port which discharges hot water to the scalp side of the droplet preventing plate is disposed, and hot water discharged from the discharge port of the nozzle is dispersed along the droplet preventing plate so as to be supplied to the user's scalp. For this reason, the flow rate of the hot water is reduced during the dispersion along the droplet preventing plate, and at the time when the hot water is separated from the edge of the droplet preventing plate and is supplied to the user's scalp, the hot water is supplied slowly to the entire scalp, and droplets are not generated. Even if a small gap is generated between the droplet preventing plate and the user's face, the droplets do not leak to the user's face, wetting it.

## Claims

### Claim 1

A scalp washing device comprising:
a container which is positioned below a user's head, said head being positioned in an upward facing position;
a hot water jetting section which supplies hot water to the user's scalp;
a droplet preventing plate which is positioned between the user's scalp portion and face;
a cover which covers the nozzle and the droplet preventing plate;
a joint portion connecting the droplet preventing plate to the cover such that the droplet preventing plate pivots about the joint portion; and
a nozzle having a single discharge port which discharges hot water to the scalp side of the droplet preventing plate,
wherein the hot water discharged from the discharge port of the nozzle is dispersed along the droplet preventing plate so as to be supplied to the user's scalp.

### Claim 2 (depends on 1)

The scalp washing device according to claim 1, further comprising:
a forehead pad which is provided on a portion of the droplet preventing plate to allow the droplet preventing portion to be located with respect to the user's head.

### Claim 3 (depends on 1)

The scalp washing device according to claim 1, further comprising:
a support fixture which supports the user's neck on an edge of the container; and
a movable supporting section provided onto the container which can adjust a gap between it and the fixing support section and supports the back of the head.

### Claim 4 (depends on 3)

The scalp washing device according to claim 3, wherein the movable supporting section is formed into a bowl shape so as to be capable of storing hot water, and the back of the head is soaked in the hot water stored in the movable supporting section.

### Claim 5 (depends on 1)

The scalp washing device according to claim 1,
wherein the cover is extended, and covers at least a part of the user's face with a predetermined space being secured between the cover and their face.
