DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a facial treatment device for removing debris such as sebum and dirt from facial skin by suction, and more particularly to a facial attachment.

[0002]

2. Description of the Related Art As disclosed in Japanese Utility Model Application Laid-Open No. 5-37234, a conventional facial treatment device is provided with a suction pump for generating a suction force and a sebum or the like by applying the suction force to the skin. Consists of attachments applied to the skin to remove debris. The attachment has a single leading edge that is tubular and contacts the skin. When a suction force is applied while the single front edge is applied to the face, it is often observed that the skin swells large enough to break the capillaries, resulting in pain and further bruising such as purpura. This is particularly true when applying a suction force to a soft skin portion such as a cheek for a long time.

[0003]

It is an object of the present invention to solve the above problems. The facial treatment device according to the present invention includes a housing 10 having a nozzle 20 and a suction pump 14 for generating a suction force through the nozzle, and a cylindrical attachment 30 having first and second ends at both axial ends. And The attachment is removably attached to the nozzle 20 at a second end, the first end has a first annular edge 34,
When the first annular edge contacts the skin of the face, the suction force acts on the skin to remove sebum and dirt from the skin. A feature of the present invention is that a buffering edge 35 is formed at a first end of the attachment 30, and the buffering edge is located radially and axially inside the first annular edge 34 so that the buffering edge 35 is sucked in the first annular edge. Attachment is formed in a shape having a central cylinder whose first end is bifurcated, and a concentric circular first annular edge is formed on the bifurcated portion with a buffer. An edge is formed. The effect of this buffering edge is to prevent the skin from swelling to the extent that it leaves pain or purpura, and to form a sub-region near the buffering edge in addition to the main region near the first annular edge. Is what you do. In each of these main areas and sub-areas, the skin is subjected to rapid suction displacement, and is a main cause for purging sebum from pores. For this reason, sebum coming out of the pores can be easily removed thereafter, for example, by being scraped off at the first annular edge. As a result, the attachment can be formed so as to have a wide suction area while preventing pain and purpura and effectively removing debris such as sebum.

Accordingly, a main object of the present invention is to provide a facial treatment device which can remove dirt and sebum safely and effectively.

[0005]

[0006] An outer flange tube extending in the axial direction so as to overlap with the front end tube portion of the center tube may be provided. The outer flange cylinder defines a first annular edge at its distal end, and is spaced apart from the buffering edge defined at the front cylindrical end of the central cylinder. The outer flange tube is radially separated from the front end tube portion to form an annular space therebetween. This annular space communicates with the inside of the central cylinder by a hole formed in the front end cylinder. Therefore, even after the buffering edge is in contact with the bulging skin, the suction force acts on the skin portion surrounded between the first annular edge and the interference edge, and the removal of sebum from the skin is enhanced. .

Further, the attachment may have the first annular edge in an elongated shape. This elongated shape is a shape having a major axis and a minor axis orthogonal to the central axis of the central cylinder. The cushioning edge is circular and spaced along the longitudinal direction from the first annular edge to form a pair of recesses along the major axis between the first annular edge and the cushioning edge. The buffering edge suppresses excessive bulging of the skin over a wide area in a cross section along the long axis direction, thereby effectively removing debris and minimizing pain, and enables processing over a wide area.

The attachment may also be detachable from the nozzle at a first end and used at a second end for facial treatment. Second
At the end, a second annular edge having a substantially elliptical shape which is in contact with the skin is formed, and the area surrounded by the second annular edge is smaller than the area surrounded by the first annular edge, which is suitable for a narrow place such as a nostril. used. The elliptical shape gives a preferential direction along the minor axis that allows the annular edge to move smoothly along the skin while providing a large processing area surrounded by the annular edge. This is based on the finding that a skin portion bulging at a portion surrounded by an annular edge has a smaller resistance to move the edge along the short axis direction than to move the edge along the long axis direction.

The above and other objects and features of the present invention will become apparent in the following embodiments explained with reference to the accompanying drawings.

[0010]

FIG. 1 shows a facial treatment device according to a preferred embodiment of the present invention. The facial device comprises a housing 10 shaped to be gripped by a user's hand, and an attachment 30 used to suck facial skin to remove dirt, sebum and other debris from the skin. The housing 10 includes a motor 11 driven by a battery 12 and a diaphragm pump 14 that generates a suction force by driving the motor. A detachable nozzle 20 protrudes from the bottom of the recess 16 formed at the upper end of the housing 10 to the attachment.
The nozzle 20 has a cylindrical shape having a through hole 21 and communicates a suction force to the attachment 30 by communicating with the decompression chamber 15 of the pump 14.

As shown in FIG. 3, the attachment 30 has a central cylinder 31 having a shaft hole 32. The central cylinder is formed with a large-diameter rear flange cylinder 43 like the large-diameter front flange cylinder 33. Both ends of the shaft hole 32 are slightly tapered so that the nozzle 20 fits closely to either the front end or the rear end of the shaft hole. FIG. 1 shows a state in which the attachment 30 is attached to the nozzle at its rear end, and FIG. 2 shows a state in which the attachment 30 is attached to the nozzle at its front end. The front flange cylinder 33 defines a front end annular edge 34,
The front end annular edge is in close contact with the skin and applies a suction force to a region surrounded by the edge. The front end of the central tube 31 overlaps with the front flange tube 33 and extends along the axial direction from the front end annular edge 34 to a point inward in the axial direction to form a buffer edge 35 there.
As shown in FIG. 6, the buffering edge is pressed against the bulging skin portion S drawn into the attachment by the suction force. As shown in FIG. 4, the buffer edge 35 has a circular shape concentric with the front end annular edge 34, and
An annular space is formed between 3 and the front end of the central tube 31. The front annular edge 34 surrounds a circular opening having a diameter D1 of 15 mm, and the cushioning edge 35 surrounds a circular opening having a diameter D2 of 8 mm. The length L of the attachment 30 is 35 mm. A ring 39 projects radially outward from the center of the central cylinder 31 in the axial direction, and is held by the user's finger for attaching the attachment.

The rear flange cylinder 43 also has a rear annular edge 4.
By defining 4 and attaching the front end of the central tube 31 to the nozzle 20, it is alternatively brought into contact with the skin. As shown in FIG. 5, the rear end annular edge 44 is formed in an elliptical shape having an opening smaller than the circular opening defined by the front end annular edge 34. The major axis D3 of the elliptical opening determined by the trailing edge 44 is 12 mm, and the minor axis D4 is 9.0 mm. This rear annular edge 44 with a small opening is provided especially for the treatment of the nostril, while the front annular edge 34 is provided for the other wide part.

First, the operation of performing face processing using the front end annular edge 34 will be described. It is desirable that the attachment be tapped against the skin so that the leading annular edge intermittently contacts the skin so that the suction force does not act on the skin for a long time to cause pain or bruising. Further, during this tapping, it is desirable that the front annular edge 34 be separated from the skin such that a portion of its peripheral edge first separates from the skin and then the remaining portion separates from the skin.
This can easily be done by twisting the wrist holding the housing when removing the attachment from the skin. As shown in FIG. 6, while the front annular edge 34 is in contact with the skin,
The skin portion S surrounded by the edge is vacuum-sucked into the attachment 30 to form a bulge, and the base of the bulge is pressed against the buffer edge 35. Therefore, the skin portion S is suddenly displaced at two different places. One location is near the front annular edge 34 and the other is near the cushioning edge 35. These are the places where sebum and similar debris are best squeezed out of the pores. The debris pulled out of the skin by the vacuum adheres to the inner wall of the attachment near the front annular edge 34 and the buffer edge 35. The debris remaining on the skin is raked and captured by the annular edge during the tapping operation described above with a wrist twist. The front end of the nozzle 20 is covered with a filter 22 to prevent debris from traveling to the pump 14. Here, when there is no cushioning edge 35, the large skin portion surrounded by the front end annular edge 34 is greatly drawn in by the softness and elasticity of the skin, and forms a greatly deformed bulging portion shown by a dotted line in FIG. Pain and even bruising.

The trailing annular edge 44 of the relatively small opening is used without tapping, but rather for sliding the edge along the skin with a nostril. Because the rear annular edge 44 is elliptical, it is easier to slide the attachment 30 along the short axis than along the long axis. In other words, when slid along the short axis, the bulging skin portion shows less resistance than when slid along the long axis.
As a result of sliding the trailing edge 44 along the skin, debris squeezed out of the pores is successfully raked by the edge and captured there. In this manner, the elliptical rear annular edge 44 secures a large processing area to effectively remove debris while facilitating the sliding operation.

FIGS. 7 and 8 show a modification of the attachment 30A, in which the buffer edge 35A is defined by four radial ribs 37. FIG. This rib 37 is located at the center tube 31
A front flange tube 3 arranged at an equal angle around the central axis of A

FIG. 9 shows another modification of the attachment 30B, in which the front flange tube 33B extends from the axial center of the center tube 31B, and the front flange tube 33B and the front end of the center tube 31B are connected to each other. Relatively long annular space 36 between
To form A hole 38 is provided at the front end of the central tube 31B, and the annular space 36 and the inside of the central tube 31B communicate with each other. Similar parts are indicated by the same numbers with "B" at the end. By providing the annular space 36 that can suck the skin area between the front end annular flange 34B and the buffer edge 35B at the end of the center cylinder 31B, this skin area is pressed against the skin portion where the buffer edge 35B bulges. Even after being drawn, it can be sucked and the front end annular edge 34B
The efficiency with which debris is removed from the entire area surrounded by the circles can be increased.

FIGS. 10 to 13 show the attachment 30.
C shows a further modification of the front end annular edge 34.
C has a substantially elliptical shape to form an elongated opening having a major axis and a minor axis, and the cushioning edge 35C is circular and extends along the front edge of the central cylinder 31C. Further, the buffer edge 35C is
It is withdrawn from the oval annular edge 34C inward, and a pair of recesses 40 are formed on the outer side thereof and spaced apart along the long axis of the front end opening. Thus, the cushioning edge 35C is spaced apart from the front annular edge 34C along the long axis by the recess 40 as shown in FIG. 11, while along the short axis, as shown in FIG.
As shown in FIG.
And continue. Attachment 30C according to this modified example

The rear end of C is provided with a rear flange cylinder 43C having an oval rear end annular edge 44C for the same purpose as described above.

The size of the elongated opening defined by the front annular edge 34C is such that the major axis D1 is 15 mm and the minor axis D2 is 8.5 m.
m, which covers a wider area of the skin than the rear elliptical opening defined by the rear end annular edge 44C. The dimension of the rear elliptical opening is 12 mm for the major axis D3 and 9 mm for the minor axis D4. The front end and rear end openings of the central tube 31C are 7.3 mm. By providing the buffer edge 35C in the radial direction and the axial direction inward with respect to the front end annular edge 34C, while performing processing over a wide area using the front end of the attachment 30C, the skin without pain or bruises. Debris can be effectively and safely removed from the wastewater. As described above, when the front end or the rear end of the attachment is slid along the skin, it is preferable to move the attachment along the short axis so as to reduce resistance from the bulging skin. The debris that has popped out of the pores is raked up and caught by the slidable edge, and when processing is performed at the front end of the attachment, it can be well collected in the recess and is easy to clean. As a matter of course, the tapping process may be performed using the front edge or the rear edge.
