Description

Electric brush device for face washing

The present invention relates to an electric brush device for face washing, and more particularly to an electric brush device for face washing which can easily replace a brush head.

In general, when applying makeup, apply a cleansing cream to your face, then rub it with your hands and then rinse.

When removing makeup from the eyelashes, apply makeup remover to the cotton pad and wipe the eyelashes down with the cotton pad.

When removing makeup from the face, if you do not apply the cleansing cream carefully, you will leave makeup on your face after washing your face. Recently, as cosmetics have become more and more fine, cosmetics that penetrate deep into the pores are easily left on the face even after washing the face, and such leftover cosmetics are liable to cause skin diseases together with pigmentation.

To apply a cleansing cream to your face more carefully when washing your face, use an electric brush device.

The electric brush device includes a handle portion, and has an end portion of a main body casing of a motor-driven mechanism including a motor therein, and includes a brush head that is rotated by the motor-driven mechanism to come into contact with a face of a user.

The electric brush device operates to open or close the motor-driven mechanism by operating a switch provided on the main body casing, and when the motor-driven mechanism is turned on, the brush head is vibrated to apply the cleansing cream to the face more delicately during face washing.

However, the above-described electric brush device mounts the brush head that contacts the face of the user to the main body casing and It is inseparable, so it is difficult to replace the brush when it is worn.

Therefore, the maintenance cost of the user using the electric brush device is high, and the use period is short due to the replacement of the brush head.

Therefore, when the user holds the handle portion 110, the brush head attached to the head coupling head 120 is attached. The above-described brush head member 300 of the member 200 faces the face of the user.

Further, the brush head coupling head portion 120 is coupled to the upper end portion of the handle portion 110, and the motor-driven mechanism transmits vibration by the brush head coupling head portion 120, thereby bringing the brush head member 300 into contact with the user's face. Shake in the state.

2 is an enlarged cross-sectional perspective view showing a state in which the brush head of the electric brush device for a face of the present invention is coupled, and FIG. 3 and FIG. 4 are enlarged cross-sectional perspective views showing the state in which the brush head is separated in the electric brush device for face washing of the present invention.

Next, an embodiment in which the above-described brush head coupling member 200 is detachably coupled to the above-described brush head coupling head 120 will be described in detail with reference to Figs. 2 to 4 .

The brush head mounting member 200 is coupled to the brush head member 300 on the front side, and protrudes to form a coupling protrusion 210 on the rear side. The front side is the direction in which the brush head member 300 faces the user's face when in use.

The head coupling head 120 has a space portion 121 that is open at the front, and a protrusion coupling hole 122 through which the coupling protrusion 210 is coupled in the back, and the coupling protrusion 210 is formed on the rear side to be exposed to the The protrusions join the contact faces 240 of the holes 122.

The brush head attachment member 200 is detachably coupled to the head coupling head 120 by coupling the coupling protrusion 210 to the protrusion coupling hole 122 formed behind the head coupling head 120.

The brush head mounting member 200 is simply separated by the above-described coupling protrusion 210 that is pushed into the protrusion coupling hole 122 toward the front side of the head coupling head 120.

In other words, the coupling projection 210 coupled to the projection coupling hole 122 is exposed to the rear surface of the head coupling head 120. Therefore, the user pushes the coupling projection toward the front side of the head coupling head 120. 210, the above-described brush head mounting member 200 is simply separated from the above-described head coupling head 120.

Further, on the inner circumferential surface of the protrusion coupling hole 122, a hollow coupling guide portion 123 that protrudes into the space portion 121 and communicates with the protrusion coupling hole 122 is formed to protrude.

Further, on the outer circumferential surface of the coupling protrusion 210, a hooking step 211 to which the hooking projection portion 123a projecting inward at one end portion of the coupling guide portion 123 is hooked is formed.

A part of the coupling guide portion 123 has a shape in which both side surfaces are cut, and an end portion side includes an elastic guiding piece 125 that is hooked to the hooking projection portion 123a of the hooking step 211. The hooking projection portion 123a is provided on the side of the hollow inlet side where the coupling protrusion 210 is coupled, that is, the end side of the elastic guiding piece 125.

In the inner space 220 of the coupling protrusion 210, when the coupling protrusion 210 is positioned in the protrusion coupling hole 122 via the coupling guide portion 123, the side surface of the coupling protrusion 210 can have a certain degree of elasticity which is intended to be recessed inside (but at this time) The degree of depression of the side surface toward the inner side is only to provide a space for the bonding protrusion 210 to smoothly reach the protrusion coupling hole 122 via the hooking protrusion portion 123a, and visually feels not to bend or the like).

In addition, the elastic guiding piece 125 can elastically open the inlet side of the coupling guiding portion 123. Therefore, when the coupling protrusion 210 is coupled into the protrusion coupling hole 122, the inlet side is elastically opened, and when After the hooking step 211 passes, the hooking step 211 is hooked to the engaging protrusion 210.

The coupling protrusion 210 forms a space 220 inside, so that a part can be accommodated when subjected to a pressing force from the outside, and the elastic guiding piece 125 can elastically open the inlet side of the protrusion coupling hole 122, thereby making the combination The protrusion 210 is smoothly coupled into the protrusion coupling hole 122 to hook the hooking step 211 to the hooking protrusion portion 123a. After the bonding is completed, the coupling protrusion 210 can be simply pushed with a small force. The hooking step 211 is released from the state in which the hooking projection portion 123a is hooked.

Further, the hooking projection portion 123a forms the first inclined surface 123b and the second inclined surface 123c on the inlet side and the outlet side of the protrusion coupling hole 122, so that the coupling protrusion 210 can be smoothly joined by a small force. In the above-mentioned projection coupling hole 122, the above-mentioned coupling projection 210 can be smoothly separated from the projection coupling hole 122 by a small force.

That is, when the coupling protrusion 210 is coupled to the protrusion coupling hole 122, the inlet side is guided by the first inclined surface 123b, so that the elastic guiding piece 125 is more smoothly opened, and when the coupling protrusion is used When the 210 is separated from the protrusion coupling hole 122, the second inclined surface 123c is guided by the outlet side, so that the elastic guiding piece 125 is smoothly opened.

Further, the inner circumferential surface of the coupling guide portion 123 is constituted by a guide inclined surface 122a whose diameter gradually increases from the inlet side to the outlet side, so that the coupling protrusion 210 is coupled to the hollow of the coupling guide portion 123. In the inner state, the gap between the guide inclined surface 122a and the outer peripheral surface of the coupling protrusion 210 gradually increases from the inlet side to the outlet side.

Therefore, the coupling projection 210 is fixed to the hooking projection portion 123a by the hooking projection 2111 on the inlet side of the projection coupling hole 122, and the guide inclined surface 122a and the above-mentioned coupling are used to the outlet side. The gap between the outer circumferential surfaces of the protrusions 210 is gradually increased, so that the contact area between the outer circumferential surface of the coupling protrusion 210 and the inner circumferential surface of the protrusion coupling hole 122 is made small, so that the coupling protrusion 210 passes through the small The force can be joined or separated from the above-mentioned protrusion bonding holes 122.

Further, when separated from the coupling protrusion 210, the contact surface 240 that brings the user's finger into contact is inclined, and the pressing operation for separation becomes smoother.

Further, the front surface of the head coupling head 120 is formed with an annular first ring protrusion 124 protruding around the outer side, and a rear surface of the brush head mounting member 200 is formed to be in close contact with the first ring combination. An annular second ring protrusion 230 on the inner side surface of the protrusion.

The first ring protrusion 124 and the second ring protrusion 230 are coupled to the head coupling head 120 in a state in which the head attachment member 200 is coupled to the protrusion coupling hole 200, that is, the coupling protrusion 210 is coupled to the protrusion coupling hole 122. In the state in which the brush head mounting member 200 is not loosened in the direction in which it is joined or separated, the state in which the brush head attaching member 200 is firmly coupled to the head coupling head 120 is maintained.

In other words, in a state in which the above-described bonding protrusion 210 and the above-described coupling guide portion 123 are coupled to the above-described bonding head portion 120 by elastic deformation, the above-described brush head mounting member 200 is externally received. If the impact is generated, looseness will occur, and if it is strongly impacted, the above-mentioned bonding protrusion 210 will be broken.

Since the first ring protrusion 124 and the second ring protrusion 230 are in contact with each other, the brush head attachment member 200 is coupled to the head coupling head 120 to prevent the state. The external impact is loosened, and the state in which the above-described brush head mounting member 200 is firmly coupled to the above-described head coupling head 120 is maintained.

The brush head member 300 is subjected to the vibration transmitted by the motor-driven mechanism and directly contacts the face of the user to apply the cleansing cream to the face more delicately when washing the face, and wears when repeatedly used.

Further, by simply pushing the above-described bonding protrusions 210 coupled to the protrusion coupling holes 122, the brush head mounting member 200 is separated from the head coupling head 120, and the brush head member 300 is easily replaced with a new one. .

The above is a preferred embodiment described in conjunction with the drawings. Here, although the terminology is specific to the user, it is intended to illustrate the invention and not to limit the scope of the invention. Thus, those skilled in the art can implement various modifications and equivalent embodiments. All of the scope of the invention should be covered by the scope of the invention without departing from the spirit and scope of the invention.
