Abstract
A stain removal device, a head portion having a beating surface; a vibration unit which is located on an extension line of an axis of the head portion orthogonal to the beating surface and vibrates the head portion in an axis direction through driving of a solenoid actuator; and a liquid supply unit which has a liquid accommodating portion capable of accommodating liquid and supplies the liquid in the liquid accommodating portion to the beating surface through vibration of the head portion generated by the vibration unit.
Claims8
A stain removal device, comprising:
- a head portion, formed with a beating surface;
- a vibration unit, which is located on an extension line of an axis of the head portion orthogonal to the beating surface and vibrates the head portion in an axis direction through driving of a solenoid actuator;
- a liquid supply unit, which has a liquid accommodating portion capable of accommodating liquid and supplies the liquid in the liquid accommodating portion to the beating surface through vibration of the head portion generated by the vibration unit;
- a main body housing, wherein the head portion protrudes from a front end portion of the main body housing;
- and
- a cover portion, detachably arranged at the front end portion of the main body housing, wherein
- a changing portion is formed on the main body housing and the cover portion, and is operative to change a length of the cover portion protruding from the front end portion of the main body housing within a range of an operating stroke of the solenoid actuator;
- wherein the changing portion comprises:
- a convex portion extending to the axis direction that is formed at one of the front end portion of the main body housing and a basal end portion of the cover portion;
- a first concave portion that has a depth configured for substantially clamping the entire convex portion and a second concave portion that is shallower than the first concave portion, the first concave portion and the second concave portion being formed at the other of the front end portion of the main body housing and the basal end portion of the cover portion;
- wherein the convex portion is operative to be clamped with the first concave portion or the second concave portion so as to change a protruding length of the cover portion.

- a vibration unit, which is located on an extension line of an axis of the head portion orthogonal to the beating surface and vibrates the head portion in an axis direction through driving of a solenoid actuator;
- a liquid supply unit, which has a liquid accommodating portion capable of accommodating liquid and supplies the liquid in the liquid accommodating portion to the beating surface through vibration of the head portion generated by the vibration unit;
- a main body housing, wherein the head portion protrudes from a front end portion of the main body housing;
- and
- a cover portion, detachably arranged at the front end portion of the main body housing, wherein
- a changing portion is formed on the main body housing and the cover portion, and is operative to change a length of the cover portion protruding from the front end portion of the main body housing within a range of an operating stroke of the solenoid actuator;
- wherein the changing portion comprises:
- a screw portion formed on an outer circumferential surface of one of the main body housing and the cover portion;
- and a nut portion corresponding to the screw portion that is formed on an inner circumferential surface of the other of the main body housing and the cover portion;
- wherein the protruding length of the cover portion is operative to be changed by increasing or decreasing a screw-in quantity of the screw portion screwed into the nut portion.
