Background

In general, makeup refers to the act of grooming the face by applying a rouge and/or a liniment and grooming the makeup to modify the user's face, thereby cleaning and/or beautifying the human body. Makeup can highlight beautiful sides and repair and/or cover defects and ugly sides, but makeup also becomes a major cause of skin problems. Therefore, to prevent skin problems, it is equally important to remove cosmetics as makeup.

The general method of removing the cosmetic is: the skin was first wetted with water and scrubbed with both hands. However, according to the face washing method of removing cosmetics by scrubbing the skin with both hands, in the case of special cosmetics, the cosmetics cannot be easily removed. That is, in the case of waterproof cosmetics such as sunscreen or makeup, it takes much time to completely remove the cosmetics from the skin by scrubbing the skin with hands. In addition, according to the method of removing cosmetics by scrubbing the skin with both hands, foreign substances in hair follicles attached to the skin cannot be effectively removed. The above problems can be solved by using an auxiliary tool for removing cosmetics, and a facial cleaning brush is a representative auxiliary tool for removing cosmetics.

An example of a technique of a cosmetic Brush is disclosed in korean utility model application laid-open No. 20-2011-.

The related art face washing brush includes a handle, a surface of which is cut and has at least one groove, and bristles fixed to one end of the handle, and the handle is formed of a shiny metallic material such as aluminum or nickel. Since the brush has an attractive appearance without jewelry decoration, it can stimulate the purchase demand and the use demand of users, and since the brush has no jewelry decoration, it can be manufactured at low cost. The related art cosmetic brush may have a good feeling of use and may use nano bristles, so that human waste in hair follicles can be completely removed because natural fibers such as wool are used.

However, although the related art face washing brush is formed of natural fiber so that skin problems can be prevented, it is inconvenient to use because cosmetics applied to the skin should be removed by directly grasping the brush and applying force. Further, with the related art face washing brush, it is difficult to massage the skin applied with thick cosmetics while removing the cosmetics.

Referring to fig. 1 to 3, a cosmetic device 100 according to an embodiment of the present invention includes a housing assembly 11, a power source 13, a rotary motor 15, a gear assembly 17, a brush plate 19, and a printed circuit board 21. The cosmetic apparatus 100 is used to rotate the brush plate 19 connected to the rotary motor 15 to remove cosmetics applied on the skin, particularly on the face. The cosmetic device 100 can remove skin lotion, waterproof cosmetics, sun cream, and color cosmetics. Further, the cosmetic device 100 can effectively remove the cosmetic applied to the bent portion by changing the shape of the brush 23 mounted on the brush plate 19, and can perform a massage while removing the cosmetic.

The housing assembly 11 includes a first housing 25 and a second housing 27, the second housing 27 being detachably connected to the first housing 25. The first and second housings 25 and 27 are combined with each other to provide a space for mounting the power supply 13, the rotary motor 15, the gear assembly 17, and the printed circuit board 21. The first housing 25 includes a head 25a to which the brush plate 19 is mounted, and a body 25b that extends from the head 25a and is easily grasped by a user.

The head 25a is provided with a rotary motor 15 and a gear assembly 17, both of which are arranged within the head 25 a. The rotating electric machine 15 drives a rotating shaft by electric power applied from the power source 13 located in the main body 25 b. The rotating motor 15 may be one employed from among any type of motor capable of rotating the brush plate 19 connected to the rotating shaft unidirectionally or bidirectionally. The power supply 13 may be a commercial power supply that supplies electric power to the rotating electric machine 15 using a primary battery or a secondary battery or an electric wire. The circuit of the power supply 13 is well known to those skilled in the art, and thus a detailed description thereof will be omitted.

The gear assembly 17 is mounted within a gear assembly cover 29 and a housing cover 31, the gear assembly cover 29 and the housing cover 31 being disposed within the head 25a and the second housing 27 of the first housing 25. A gear assembly cover 29 is mounted on the rotary motor 15, and the rotary motor 15 is disposed between an inner wall of the second housing 27 in the housing assembly 11 and the gear assembly cover 29. The gear assembly cover 29 includes a gear housing 29a and a switch section base 29b extending from the gear housing 29 a. The gear housing 29a, together with a housing cover 31 disposed adjacent the head 25a, encases the gear assembly 17.

The gear assembly 17 is connected to a rotating shaft of the rotating motor 15 passing through the gear housing 29 a. The gear assembly 17 transmits the rotation of the rotation shaft to the brush plate 19 using a gear ratio between the plurality of gears 17a to 17 d. The gears 17a to 17d may be referred to as a first gear 17a, a second gear 17b, a third gear 17c, and a fourth gear 17d in this order. The deceleration of the rotation shaft by the gears 17a to 17d is well known to those skilled in the art, and thus a detailed description thereof will be omitted. The gear assembly 17 is secured by a gear securing portion 33 located in the housing cover 31 and passes through the housing cover 31 and the head portion 25a of the first housing 25 for connection to the brush plate 19. Thus, the brush plate 19 can be rotated at a reduced rotational speed, which is achieved by the gear ratio between the gears 17a to 17d provided in the gear assembly 17.

Meanwhile, the printed circuit board 21 is arranged between the switch section base 29b extending from the gear housing 29a and the inside of the second case 27. The printed circuit board 21 includes a controller 35 and a switch unit 37 mounted thereon, and the controller 35 controls rotation of the rotating shaft of the rotating motor 15. The switch section 37 switches on/off of the power applied from the power supply 13 to the rotary electric machine 15, and adjusts the rotation speed of the rotary shaft of the rotary electric machine 15 under the control of the controller 35. The switch portion 37 passes through the switch portion base 29b and is enclosed by the switch portion cover 39. The opening and closing portion cover 39 passes through an opening and closing portion hole 41 formed in the main body 25b of the first housing 25, and is exposed from the first housing 25. Thus, the user can hold the main body 25b and can push the switch cover 39 exposed above the switch hole 41 to operate the switch 37.

A case plug 43 is installed at the end of the main body 25b in order to replace or take out the power source for charging. The housing plug 43 may be removably connected to the housing assembly 11 in a known manner, such as by a screw fitting. In this case, a filler 45 may be installed in the housing plug 43 to prevent liquid or vapor from entering into the power source 13.

Referring to fig. 2 and 4, the brush plate 19 employed in the cosmetic apparatus 100 according to the embodiment of the present invention includes a brush 23 having a plurality of brush filaments. The brush 23 may be coated with a material that reacts with air and changes color with the passage of time, or a material that reacts with cosmetics and changes color with the passage of time, so that the replacement period of the brush 23 can be indicated.

For example, the coating material is applied so as to confirm the replacement period when it is used more than once a day for three months, the coating material is discolored with the lapse of time or with continuous use, or the coating material is discolored as the cosmetic is dissolved and the concentration thereof becomes thin. Furthermore, the coating material may be an edible dye which has a safety guarantee for the safety of the skin. In this case, the color of the coating material may be different from the original color of the brush filaments, such as blue, green, orange, yellow, magenta, or purple, and the like, and the coating material may be partially coated on the ends of the brush filaments or throughout the entire brush filaments to appear colored.

The brush 23 may be made of polybutylene terephthalate (PBT), nylon, polyester velvet, or polyurethane film. In the case where the brush 23 is made of PBT, the brush filaments may be 0.07 to 0.13mm thick and 8 to 14mm long. In this case, the brush filaments may be tapered toward their ends so as to easily remove human waste from the pores and improve the soft feeling of the skin when the brush filaments are brought into contact with the skin.

For example, the brush filaments may be implanted in the brush plate 19 in units of 11mm to 13 mm. In this case, the brush filaments may be 96 to 100 micrometers thick on the first surface S of the brush plate 19, and may be 6 to 10 micrometers thick at a position spaced apart from the ends of the brush filaments by 0.1 mm. Further, in order to maintain the elasticity of the brush filaments, the brush filaments may be tapered to a thickness of about 0.01mm at a gentle slope from the bottom thereof, which is spaced from the distal ends of the brush filaments by 2mm to 3 mm.

The brush filaments may be implanted in 1.5mm to 1.6mm holes in the first surface S of the brush plate 19, and may be disposed on the first surface S in the range of 100 to 200 filaments. In case the brush filaments are thinner than 0.07mm, e.g. 0.04mm to 0.06mm thick, more than 200 filaments may be implanted in the first surface S. The brush 23 may be coated with a material that changes color over time and an antimicrobial material.

When the brush 23 is made of polyester velour, the brush filaments are woven in the form of velour having 108, 144 or 288 fiber filaments 3 μm thick, and may be 2mm to 3mm long. When used with a cleaning product, the brush filaments can produce a dense, coherent and rich foam.

The first surface S of the brush plate 19 on which the brushes 23 are mounted is flat or curved. In the case where the first surface S is flat, the brush 23 may be parallel to the first surface S or may be curved to be able to perform a massage function. For example, the respective brush filaments may have the same length so as to be parallel to the first surface S, or may be implanted in different lengths so as to have a massage function.

On the other hand, as shown in fig. 5a to 5c, the surface of the brush plate 19 on which the brush 23 is mounted may have a valley V and a peak P. The lengths of the brush filaments are the same, and the ends of the filaments may be bent to have a massage function. Thus, the cosmetic device 100 can use the brush plate 19 as follows: the brush plate 19 has a curved surface formed by the ends of the brush filaments, so that the brush plate 19 can be rotated to remove cosmetics covering the skin and massage the skin.

Although the preferred embodiments of the present invention have been disclosed for illustrative purposes, those skilled in the art will appreciate that various modifications, additions and substitutions are possible, without departing from the scope and spirit of the invention as disclosed in the accompanying claims.
