Abstract

A facial treatment device wherein an air pumping means and a rotary member are driven by a rotary power source so as to perform skin cleaning and massaging actions with sucking and rotary functions through a sucking or rotary attachment. A stationary shaft having an axial hole is provided in the device to have an end of the hole communicated with air-intake side of the pumping means and the other end exposed to the exterior, and the rotary member is rotatably supported coaxially with the stationary shaft. The sucking attachment is mounted to the stationary shaft at said the other end of its axial hole, whereas the rotary attachment is mounted, in place of the sucking attachment, to the rotary member made accessible thereto on the same side with said end of the stationary shaft to which the sucking attachment is mounted. Preferably, the common axis of the stationary shaft and rotary member is disposed to intersect at right angles the axis of rotary output shaft of the power source.

Claims

1. A facial treatment device in combination with detachable sucking and rotary attachments, said device comprising a housing, a rotary power source housed in said housing and including an output shaft, an air pumping means housed in the housing to be driven by said rotary power source, a stationary shaft disposed at right angles to said output shaft and forming an axial air-flow path communicated at one end with air-intake side of said pumping means and at the other end with the exterior of the housing, and a rotary member including a rotary shaft supported coaxially relative to said stationary shaft to be rotated thereabout by the rotary power source, an end of the stationary shaft on the side of said other end of the air-flow path projecting beyond said rotary shaft, said end of said stationary shaft and said rotary shaft of said rotary member being accessible on a single side of the housing for selectively mounting and detaching the sucking attachment to and from said end of the stationary shaft and the rotary attachment to and from said rotary shaft, said sucking attachment communicating with said air flow path when attached.

2. A facial treatment device according to claim 1, wherein said air pumping means comprises a diaphragm of a resilient material and having an air intake valve abutting said one end of said axial air-flow path of the stationary shaft, said rotary member comprises a crown gear having at the periphery gear teeth errected vertically with respect to the plane of its body, and said diaphragm and crown gear are arranged in parallel to and on respective sides of said axis of the output shaft of the rotary power source.

3. A facial treatment device according to claim 2, wherein said diaphragm is provided with a connecting extension formed integrally therewith for connecting the diaphragm to the output shaft of the rotary power source, and said extension is disposed in a space defined by the diaphragm and the errected gear teeth and body of said crown gear.

4. A facial treatment device according to claim 2, wherein said rotary power source comprises a motor having a drive gear secured to said output shaft, said drive gear having an eccentric shaft, said crown gear is provided adjacent said rotary shaft with radial ribs defining an inner space along the rotary shaft and an outer space along the errected gear teeth, said inner space allowing said rotary attachment to be mounted on the rotary shaft, and said outer space allowing a connecting extension integrally formed with said diaphragm to be accommodated therein as connected to said eccentric shaft.

9. A facial treatment device according to claim 1, wherein said sucking attachment is of a substantially cup shape having an axial hole and mounted to said stationary shaft in an air-tight manner about the shaft except said axial hole of the attachment for allowing an air flow to pass therethrough to said air-flow path of the shaft.

10. A facial treatment device according to claim 1, wherein said rotary attachment is a brush member having brush bristles and resilient extensions axially extending and mounted to said rotary member at said extensions to be thereby rotated.

11. A facial treatment device according to claim 10, wherein said brush member includes a stationary brush fitted to the housing and having brush bristles encircling said brush bristles of said brush member.

12. Apparatus according to claim 1 wherein said housing includes top and bottom surfaces disposed substantially perpendicular to said rotary and stationary shafts, said top and bottom surfaces being generally flat.

5. A facial treatment device in combination with detachable sucking and rotary attachments, said device comprising a housing, a rotary power source housed in said housing, an air pumping means housing in the housing to be driven by said rotary power source, a stationary shaft forming an axial air-flow path communicated at one end with air-intake side of said pumping means and at the other end with the exterior of the housing, and a rotary member including a rotary shaft supported coaxially relative to said stationary shaft to be rotated thereabout by the rotary power source, an end of the stationary shaft on the side of said other end of the air-flow path projecting beyond said rotary shaft, said end of said stationary shaft and said rotary shaft of said rotary member being accessible on a single side of the housing for selectively mounting and detaching the sucking attachment to and from said end of the stationary shaft and the rotary attachment to and from said rotary shaft, said stationary shaft and rotary member disposed along an axial line which intersects at right angles the axis of an output shaft of said rotary power source, said air pumping means comprising a diaphragm of a resilient material and having an air intake valve abutting said one end of said axial air-flow path of the stationary shaft, said rotary member comprising a crown gear having its periphery gear teeth extending perpendicularly with respect to the plane of its body, and said diaphragm and crown gear arranged in parallel to and on respective sides of said axis of the output shaft of the rotary power source.

6. A facial treatment device according to claim 5, wherein said stationary shaft extend out of said rotary member at said end for mounting thereto said sucking attachment.

7. A facial treatment device according to claim 6, wherein a bushing having at an axial end a resilient member is secured to said extended end of the stationary shaft, whereby said rotary member is supported on the shaft rotatably by said resilient member and the sucking attachment is mounted to the shaft through said bushing.

8. A facial treatment device according to claim 7, wherein said bushing is provided around the periphery with a resilient packing so that the sucking attachment when mounted is resiliently held by said packing and any clearance between the bushing and the attachment is air-tightly sealed by the packing to achieve at an open end of the attachment an air sucking function.
