Abstract
An automatic hair washing device includes a washing part including a cover member having a head holding space where a human head is placed, a plurality of contacts each formed of a rod-shaped member and each disposed on an inner face of the cover member in an axially movable manner, and energization part for energizing the contacts toward the head holding space. The washing part is disposed such that the cover member is movable along the human head. The energization part is configured to energize the contacts toward the head holding space such that the contacts, which is in contact with the human head, applies approximately constant forces to the human head even when the contacts are moved.
Claims12
An automatic hair washing device comprising
- a washing part including:
- a cover member having a head holding space where a human head is placed;
- a plurality of contacts each formed of a rod-shaped member and each disposed on an inner face of the cover member in an axially movable manner;
- and
- energization means for energizing the contacts toward the head holding space,
- wherein
- the washing part is disposed such that the cover member is movable along the human head,
- the energization means includes:
- an accommodation space where a fluid is retainable, the accommodation space being formed in a hollow shape and separated from the head holding space by an inner wall of the cover member;
- and
- a fluid pressure adjustment part to adjust a pressure of the fluid accommodated in the accommodation space at a predetermined level,
- the fluid accommodated in the accommodation space is a compressive fluid, and
- the fluid pressure adjustment part is configured to adjust the pressure of the fluid accommodated in the accommodation space at a pressure to energize the contacts toward the head holding space such that the contacts being in contact with the human head apply approximately constant forces to the human head even when the contacts are moved.
An automatic hair washing device comprising
- a washing part including:
- a cover member having a head holding space where a human head is placed;
- a plurality of contacts each formed of a rod-shaped member and each disposed on an inner face of the cover member in an axially movable manner;
- and
- energization means for energizing the contacts toward the head holding space,
- wherein
- the washing part is disposed such that the cover member is movable along the human head,
- each of the contacts is formed of a one end-closed tubular member having a closed end with which the human head is in contact, the one end-closed tubular member being formed in a hollow shape and disposed such that an axis thereof extends orthogonal to the inner face of an inner wall of the cover member,
- the energization means includes a spring member disposed inside each contact to energize the corresponding contact toward the head holding space, and
- the spring member is adjusted such that an energizing force to be applied to the corresponding contact when the contact protrudes in a minimum amount becomes approximately equal to an energizing force to be applied to the corresponding contact when the contact protrudes in a maximum amount.
