Stain removal device

A stain removal device, comprising:

• a cassette mechanism, which comprises a head portion having a beating surface and a water supply bottle for accommodating liquid, wherein water supply paths are formed from the water supply bottle and throughout the head portion;
• and
• a device main body, which comprises a vibration unit,
• wherein the vibration unit is mounted by pressing the cassette mechanism and detached by pulling out the vibration unit and is configured to apply a vibration to the cassette mechanism towards a direction substantially orthogonal to the beating surface of the head portion through supplied electric power,
• wherein with the vibration generated by the vibration unit to the cassette mechanism, the stain removal device supplies the liquid to the beating surface of the head portion from the water supply bottle through the water supply paths,
• wherein the water supply bottle of the cassette mechanism comprises a bottle main body and a cover body screwed with the bottle main body so as to be capable of opening and closing, and the head portion is integrally provided on the cover body,
• wherein the cover body is a bottomed member having an outer barrel screwed with an outer periphery of an end portion of the bottle main body to constitute a connection portion, the water supply paths comprises a first water supply path from a bottom of the cover body and throughout the beating surface of the head portion and a second water supply path from the end portion of the bottle main body throughout the bottom of the cover body, a first throttling portion is formed in a region of the first water supply path, and a sealing member having a second throttling portion is detachably provided in a region of the second water supply path, the scaling member is tightly clamped between an end surface of the bottle main body and a bottom of the cover body, and the sealing member has a bottom portion and an upright wall which rises from a periphery of the bottom portion for blocking liquid flowing through the second water supply path from entering into screwing portions of the cover body and the bottle main body.
