DETAILED DESCRIPTION

Overview

[0012] The present disclosure is directed towards a makeup application apparatus or a makeup brush system that may enable a user to apply makeup to facial skin. The apparatus may be a makeup brush that may include a handle and a removable brush head. A brush head top portion may include a plurality of bristles through which the user may apply and pat makeup on the facial skin. A brush head bottom portion may removably attach with a handle top portion via magnetic attachment means.

[0013] In some aspects, the brush head may include a metal disc and the handle top portion may include a magnetic switchable device that may magnetically couple the brush head with the handle. The magnetic switchable device may enable selective attachment of the brush head with the handle. For example, the magnetic switchable device may be activated to enable magnetic coupling between the handle and the brush head, and may be deactivated to disable magnetic coupling between the handle and the brush head. When the magnetic coupling may be deactivated, the user may replace an existing brush head with a new brush head on the handle (and again activate the magnetic coupling/magnetic switchable device), thereby making it easy for the user to replace brush heads based on user's requirements.

[0014] In some aspects, the magnetic switchable device may be activated or deactivated via an actuator. The actuator may be a mechanical actuator or an electronic actuator. The mechanical actuator may be a lever that may be disposed at the handle, which may be configured to mechanically activate the magnetic switchable device. The electronic actuator may be a button disposed at the handle, which may be configured to receive user inputs. The button may be communicatively coupled to a control system of the makeup brush, which may actuate a makeup brush battery based on the user inputs. When the battery may be actuated, the battery may supply current/power to the magnetic switchable device to activate the magnetic switchable device (e.g. to magnetically couple the handle and the brush head).

[0015] In some aspects, the magnetic switchable device may include a top plate and a bottom plate. The top plate and the bottom plate may include a plurality of recesses. Each recess may be configured to receive a magnet keeper. Adjacent recesses may be separated by a slot configured to receive and hold a magnet. The magnet keepers placed in the recesses may be disposed across the magnetic poles associated with the magnets, to preserve the magnet strength.

[0016] The present disclosure discloses a makeup brush that enables a user to use the makeup brush for applying different cosmetics on the user's face, by interchangeably connecting the brush heads to the handle. This may enhance user's convenience and reduce cost as the user may not be required to buy different makeup brushes, and instead may buy only brush heads and may interchangeably use the brush heads to apply the makeup.

[0017] These and other advantages of the present disclosure are provided in detail herein.

Illustrative Embodiments

[0018] The disclosure will be described more fully hereinafter with reference to the accompanying drawings, in which example embodiments of the disclosure are shown, and not intended to be limiting.

[0019] FIG. 1 depicts an example makeup brush system 100 (or a makeup brush apparatus) in accordance with the present disclosure. FIG. 1 will be described in conjunction with FIGS. 2-6. FIG. 2 depicts an exploded view of the makeup brush system 100, and FIG. 3 depicts an example magnetic switchable device of the makeup brush system 100. Further, FIG. 4 depicts a bottom view of an example brush head of the makeup brush system 100, and FIG. 5 depicts a top view of an example handle of the makeup brush system 100. FIG. 6 depicts an example actuation mechanism of the makeup brush system 100 in accordance with the present disclosure.

[0020] The makeup brush system 100 (hereinafter referred to as makeup brush 100) may enable a user to apply makeup on user's face. For example, the user may use the makeup brush 100 to apply cosmetics or foundation on the user's face. The makeup may be in powder or semi-solid form. The makeup brush 100 may include interchangeable brush heads, which may enable the user to apply different kinds of cosmetics on the user's face using the makeup brush 100. For instance, the user may connect a foundation brush head to the makeup brush 100 to apply foundation, a blush brush head to apply blush, a concealer brush head to apply concealer, a highlight brush head to apply highlighter, an eyeshadow color brush head to apply eyeshadow, a nose shadow brush head to apply nose shadow, and/or the like.

[0021] The makeup brush 100 may include a handle 102 and a brush head 104. The brush head 104 may be removably coupled to the handle 102. In some aspects, the brush head 104 may be magnetically coupled to the handle 102. The handle 102 and the brush head 104 may include magnetic attachment means/mechanisms that may enable removable attachment of the brush head 104 with the handle 102. The details of the magnetic attachment means are described later in the description below.

[0022] The handle 102 may include a handle top portion 202 and a handle bottom portion 204 (as shown in FIG. 2). In some aspects, the handle 102 may be shaped as an elongated hollow cylinder (or a hollow cuboid) having a length in a range of 6 to 10 inches. In some aspects, the handle 102 may have same diameter throughout the handle length (i.e., same from the handle top portion 202 to the handle bottom portion 204). In other aspects, the handle 102 may have a tapered diameter (or width), with a handle bottom portion 204 diameter less than a handle top portion 202 diameter. In an exemplary aspect, a handle top portion diameter may be in a range of 0.75 to 2 inches, and a handle bottom portion diameter may be in a range of 0.5 to 1.5 inches. The handle 102 may be made of plastic, fiber, wood, metal, and/or the like.

[0023] The brush head 104 may include a brush head top portion 206 and a brush head bottom portion 208 (as shown in FIG. 2). The brush head top portion 206 may include a plurality of bristles 210 that may enable the user to apply makeup on the user's skin. The plurality of bristles 210 may be made of nylon, polyester, synthetic Thermoplastic Polyurethanes (TPU), and/or the like. Each bristle 210 may have a length in a range of 1 to 2 inches (which may be vary based on the brush head type). In some aspects, the brush head bottom portion 208 may be hollow, and may be made of any material such as metal, plastic, etc.

[0024] In some aspects, the brush head 104 may have a same diameter throughout the brush head length (i.e., same from the brush head top portion 206 to the brush head bottom portion 208). In other aspects, the brush head 104 may have a tapered diameter (or width), with a brush head bottom portion 208 diameter greater than a brush head top portion 206 diameter. The brush head bottom portion 208 may be configured to removably couple with the handle top portion 202. In some aspects, the brush head bottom portion 208 diameter may be equivalent to the handle top portion 202 diameter. In other aspects, the brush head bottom portion 208 diameter may be different from the handle top portion 202 diameter.

[0025] The brush head bottom portion 208 and the handle top portion 202 may include the magnetic attachment means that may enable removable attachment of the brush head bottom portion 208 with the handle top portion 202. In some aspects, the brush head bottom portion 208 may include a ferrous material (as a part of the magnetic attachment means). The ferrous material may be a metal disc 212 that may be circular in shape. An example bottom view of the brush head 104 with the metal disc 212 is depicted in FIG. 4.

[0026] In some aspects, the handle 102 (specifically the handle top portion 202) may include a magnetic switchable device 214 (as a part of the magnetic attachment means) that may be configured to magnetically couple with the metal disc 212, to selectively enable magnetic coupling between the handle 102 with the brush head 104 (e.g., to removably attach the handle 102 with the brush head 104). The magnetic switchable device 214 may be disposed at the handle top portion 202. An example top view of the handle 102 with the magnetic switchable device 214 is depicted in FIG. 5.

[0027] The magnetic switchable device 214 may be a device configured to selectively turn-on or turn-off external magnetic field, to selectively attach/detach external items (such as the brush head 104) to the magnetic switchable device 214. The magnetic switchable device 214 may be configured to operate in a first mode and a second mode. In the first mode, the magnetic flux emanating from the magnetic switchable device 214 may be directed internally or within the magnetic switchable device 214. In this mode, the magnetic switchable device 214 may not be configured to attach the external item or the metal disc 212. Stated another way, in the first mode, there is no magnetic coupling (or no magnetic attraction) between the magnetic switchable device 214 and the external item/metal disc 212. In the second mode, the magnetic flux is directed externally or outside the magnetic switchable device 214. In this mode, the magnetic switchable device 214 may be configured to attach/couple with the external item/metal disc 212. Stated another way, in the second mode, there exists magnetic coupling (or magnetic attraction) between the magnetic switchable device 214 and the external item/metal disc 212.

[0028] Thus, in the first mode, the magnetic state associated with the magnetic switchable device 214 is deactivated (or the magnetic switchable device 214 is demagnetized). In the second mode, the magnetic state associated with the magnetic switchable device 214 is activated (or the magnetic switchable device 214 is magnetized). When the magnetic switchable device 214 is activated, the magnetic switchable device 214 may allow the brush head 104 to magnetically couple with the handle 102. When the magnetic switchable device 214 is deactivated, the magnetic switchable device 214 may not allow the brush head 104 to magnetically couple with the handle 102. Stated another way, the magnetic switchable device 214 may be activated to turn-on the magnetic state associated with the magnetic switchable device 214, and the magnetic switchable device 214 may be deactivated to turn-off the magnetic state associated with the magnetic switchable device 214. The magnetic switchable device 214 may allow the metal disc 212 to magnetically couple with the magnetic switchable device 214 when the magnetic state associated with the magnetic switchable device 214 is turned-on.

[0029] In some aspects, the magnetic switchable device 214 may be activated or deactivated by using an actuator 216. The actuator 216 may activate/deactivate the magnetic switchable device 214. Stated another way, the actuator 216 may switch magnetic switchable device operation between the first mode and the second mode.

[0030] In some aspects, the actuator 216 may be a mechanical actuator (such as a lever 602 or rod 602, as shown in FIG. 6) that may be mechanically coupled with the magnetic switchable device 214. The mechanical actuator may be configured to mechanically actuate (e.g., mechanically activate/deactivate the magnetic state of) the magnetic switchable device 214. In some aspects, the lever 602 may be disposed at a handle 102 external surface. In an exemplary aspect, the lever 602 may be disposed in proximity to the handle top portion 202 (e.g., in proximity to the magnetic switchable device 214). In another aspect, the lever 602 may be disposed in proximity to the handle bottom portion 204. In yet another aspect, the lever 602 may be disposed in between the handle top portion 202 and the handle bottom portion 204.

[0031] In an exemplary aspect, the handle 102 may include a groove 604 in which the lever 602 may be positioned. The groove 604 may be a horizontal groove having an axis perpendicular to the handle longitudinal axis. The groove 604 may include an opening 606 through which the lever 602 may be mechanically coupled to the magnetic switchable device 214 (e.g., a top plate 302 or a bottom plate 304, described below). The lever 602 may be configured to rotate in the opening 606 in a predetermined angle range (e.g., 0 to 180 degrees). For example, the lever 602 may be configured to rotate clockwise or counter-clockwise in the opening 606 to activate/deactivate the magnetic state of the magnetic switchable device 214. The rotation of the lever 602 may mechanically activate/deactivate the magnetic state of the magnetic switchable device 214.

[0032] In alternative aspects, the actuator 216 may an electronic actuator that may electronically actuate (e.g., electronically activate/deactivate the magnetic state of) the magnetic switchable device 214. In an exemplary aspect, the actuator 216 may be a button (e.g., a push button) that may be disposed at a handle 102 external surface, anywhere along the handle 102 length. The button may be configured to receive user inputs (e.g., a user press of the button) to activate or deactivate the magnetic state associated with the magnetic switchable device 214 (or to magnetically attach/detach the brush head 104 to/from the handle 102).

[0033] In yet another aspect, the actuator 216 may be a Human-Machine Interface (HMI, not shown) that may be disposed on the handle 102 exterior surface. The user may input a command (or provide user inputs) on the HMI to activate or deactivate the magnetic state associated with the magnetic switchable device 214. In yet another aspect, the actuator 216 may be or include a mechanical dialer that may be disposed on the handle 102 exterior surface, and the user may use the dialer to activate or deactivate the magnetic state associated with the magnetic switchable device 214.

[0034] In some aspects, when the actuator 216 is an electronic actuator or the HMI, the actuator 216 may be communicatively coupled to a control system 218 that may be disposed inside the handle 102. The control system 218 may be configured to obtain the user inputs (or a trigger signal) from the actuator 216 when the user provides the inputs or activates the actuator 216. Responsive to obtaining the trigger signal/user inputs the control system 218 may activate or deactivate (or cause activation/deactivation of) the magnetic state associated with the magnetic switchable device 214 based on the obtained inputs. To activate or deactivate the magnetic state, the control system 218 may transmit actuation/command signals to a battery 220 that may be disposed inside the handle 102. The battery 220 may be configured to supply current/power to magnets (shown as magnets 312 in FIG. 3) disposed inside the magnetic switchable device 214, based on the actuation/command signals. In some aspects, the battery 220 may be a rechargeable battery that may be charged via a Universal Serial Bus (USB) charger.

[0035] In some aspects, the magnetic switchable device 214 may include a top plate 302 and a bottom plate 304, which may contact each other and be disposed inside the handle 102. The top plate 302 and the bottom plate 304 may be positioned inside the handle top portion 202 using a retaining member (not shown). The retaining member may be a structure configured to position the top plate 302 and the bottom plate 304 inside the handle 102. In some aspects, one plate (e.g., the top plate 302) may be fixed and the other plate (e.g., the bottom plate 304) may be configured to move clockwise or counter-clockwise relative to the top plate 302. For example, bottom plate 304 may move clockwise or counter-clockwise relative to the top plate 302. Alternatively, the top plate 302 may move clockwise or counter-clockwise relative to the bottom plate 304.

[0036] In an exemplary aspect, the top plate 302 and the bottom plate 304 may be identical. In another aspect, the top plate 302 and the bottom plate 304 may be non-identical. In some aspects, the top plate 302 and the bottom plate 304 may be of any shape including, but not limited to, circular, square, rectangular, oval, and/or the like. In some aspects, the shape of the top plate 302 and the bottom plate 304 may correspond to the shape of metal disc 212.

[0037] The top plate 302 and the bottom plate 304 may be made of any material including, but not limited to, steel, aluminum, brass, and/or the like. The top plate 302 and the bottom plate 304 may be of any dimensions. In some aspects, the diameter of the top plate 302 and the bottom plate 304 may be less than a handle 102 diameter (e.g., an internal diameter). In an exemplary aspect, a top plate thickness may be same as a bottom plate thickness. In another aspect, the top plate thickness may be different from the bottom plate thickness. For example, the top plate thickness may be less than the bottom plate thickness.

[0038] In some aspects, each of the top plate 302 and the bottom plate 304 may include a plurality of recesses 306. Each recess 306 may be configured to receive a magnet keeper 308. In some aspects, the plurality of recesses 306 may be located at a top plate 302 lower surface, and at a bottom plate 304 upper surface. The top plate 302 lower surface may face towards the bottom plate 304 upper surface. In some aspects, the plurality of recesses 306 may be disposed at a periphery or in proximity to the edges of the top plate 302 and the bottom plate 304. For example, when the top plate 302 and the bottom plate 304 may be circular, the plurality of recesses 306 may be disposed at or in proximity to a circumference of the circular plate, and at a predetermined distance from adjacent recesses. In an exemplary aspect, the top plate 302 and the bottom plate 304 may include six recesses. In further aspects, the plurality of recess 306 may be disposed in any pattern.

[0039] In some aspects, the recess 306 may be of any shape including, but not limited to, circular, square, hexagonal (as depicted in FIG. 3), and/or the like. In some aspects, the recess shape may correspond to the magnet keeper shape, to enable the recess 306 to receive and hold the magnet keeper 308 inside the recess 306. The magnet keeper 308 may be made of soft iron, and may be shaped as a circular ring. In an exemplary aspect, each recess 306 may be hexagonal in shape, and may be configured to receive the circular ring, which enables easy insertion/removal of the magnet keeper 308 to/from the recess 306. In further aspects, the recess 306 may be of any dimensions. In an exemplary aspect, a recess diameter may be 5-15% of the top/bottom plate diameter. In some aspects, the recess dimensions may correspond to the magnet keeper dimensions. For example, the recess 306 depth may be same as the magnet keeper depth.

[0040] In further aspects, each of the top plate 302 and the bottom plate 304 may include a plurality of slots 310. Each slot 310 may be configured to receive and hold a magnet 312. The magnets 312 in the top plate 302 and the bottom plate 304 enable magnetic coupling between the top plate 302 and the bottom plate 304, and magnetic coupling between the top plate 302 and the metal disc 212.

[0041] The slots 310 may be of any shape and dimensions. The shape and dimensions of the slots 310 may correspond to the shape and dimensions of the magnets 312. For example, the slot 310 may be a circular slot and the magnet 312 may be a magnet bar. The slot 310 may be disposed between adjacent recesses, and may interconnect the adjacent recesses. A person ordinarily skilled in the art may appreciate from the description above that one magnet 312 is disposed between adjacent magnet keepers 308.

[0042] The magnets 312 may be disposed in the slots 310 in any pattern. In an exemplary aspect, the magnets 312 may be disposed such that similar poles of the adjacent magnets 312 may face each other, as shown in FIG. 3. For example, a north pole of a first magnet may face a north pole of a second magnet (placed adjacent to the first magnet). One magnet keeper may be positioned between the first magnet and the second magnet. The magnet keeper may be placed across the magnetic poles of the adjacent magnets. Such placement of the magnets and the magnet keeper enables the magnet keeper to preserve the magnets strength.

[0043] In operation, when the top plate 302 and the bottom plate 304 are positioned in proximity to each other, and the top plate 302 lower surface (having the recesses 306 and the slots 310) faces towards the bottom plate 304 upper surface (having the recesses 306 and the slots 310), the top plate 302 and/or the bottom plate 304 may automatically align themselves at a first position of the magnetic switchable device 214. In the first position, the north pole of the magnets 312 in the top plate 302 may be oriented to face the south pole of the magnets 312 in the bottom plate 304. Thus, the magnetic flux emanating from the magnets 312 may be present or stay enclosed within the magnetic switchable device 214, and may not move outside. In this position, the magnetic switchable device 214 may be in a demagnetized state or deactivated (or the magnetic state is turned-off). In the demagnetized state, the magnetic switchable device 214 may not be configured to magnetically attach to the external item such as the metal disc 212. Thus, in the first position, the brush head 104 may not attach to the handle 102.

[0044] To attach the brush head 104 to the handle 102, the user may actuate the magnetic switchable device 214 to move the magnetic flux to the outside of the magnetic switchable device 214 (i.e., outside of the top plate 302 and the bottom plate 304). For example, to attach the brush head 104 to the handle 102, the magnetic switchable device 214 may be actuated (via the actuator 216) to move the magnetic flux outside of the top plate 302 upper surface. When the magnetic flux moves outside the top plate 302 (and the bottom plate 304), the magnetic state associated with the magnetic switchable device 214 may be turned-on.

[0045] In some aspects, the magnetic switchable device 214 may be actuated by the lever 602 disposed at the handle 102 (as described above). The user may use the lever 602 (that may be attached to the top plate 302 or the bottom plate 304) to move the top plate 302 (or the bottom plate 304) to cause the magnetic switchable device 214 to move from the first position to a second position. In an exemplary aspect, the user may use the lever 602 to move the bottom plate 304 in a clockwise or a counter-clockwise direction relative to the top plate 302, to cause the magnetic switchable device 214 to move from the first position to the second position.

[0046] In the second position, the north pole of the magnets 312 in the top plate 302 may be oriented to face the north pole of the magnets 312 in the bottom plate 304. In this configuration, the magnetic flux may not stay enclosed within the magnetic switchable device 214, and may move outside. Therefore, the magnetic state associated with the magnetic switchable device 214 may be activated when the top plate 302/bottom plate 304 may be in the second position. The user may use the lever 602 again to deactivate the magnetic state associated with the magnetic switchable device 214 by moving the top plate 302/bottom plate 304 from the second position to the first position.

[0047] Alternatively, the magnetic switchable device 214 may be actuated by the button disposed at the handle 102 (as described above). The user may use the button to activate or deactivate the magnetic state. When the user desires to activate the magnetic state associated with the magnetic switchable device 214, the user may press the button. When the user presses the button, the control system 218 may receive the trigger signal from the button, and transmit an actuation signal to the battery 220 to supply current/power to the magnets 312 (via the coils) disposed in the top plate 302 (or the bottom plate 304). When the current is passed through the magnets 312, the magnetic poles associated with the magnets 312 reverse and the magnetic flux moves out of the top plate 302 and the bottom plate 304, thereby activating the magnetic state associated with the magnetic switchable device 214.

[0048] When the magnetic state of the magnetic switchable device 214 is turned-on or activated, the magnetic switchable device 214 may generate attractive force, which may enable the metal disc 212/brush head 104 to attach with the magnetic switchable device 214/handle 102 (e.g., the handle top portion 202). The user may deactivate the magnetic state associated with the magnetic switchable device 214 (via the actuator 216) to detach the brush head 104 from the handle 102. Thus, the brush head 104 may be easily attached or detached from the handle 102, thereby allowing the user to use interchangeable brush heads with a single handle.

[0049] Although the present disclosure discloses the on/off interchangeable brush system for makeup, the present disclosure should not be construed limiting to the makeup brushes. The present disclosure may be applied to other brushes such as artistic brushes, without departing from the scope of the present disclosure.

[0050] In further aspects, the handle 102 may include additional features that may allow the user to apply the makeup. For example, the handle 102 may include a dispensing mechanism 222 to dispense facial cream (or other cosmetic products like lotion, gel, etc.) out of the brush head 104. The dispensing mechanism 222 may include a storage space to store the facial cream. In addition, the dispensing mechanism 222 may include delivery passages (not shown) to deliver the facial cream onto the user's face via the brush head top portion 206. In some aspects, the user may use appropriate brush head to dispense the facial cream from the brush head top portion 206.

[0051] FIG. 7 depicts another magnetic switchable device 702 of the makeup brush system 100 in accordance with the present disclosure. The magnetic switchable device 702 may be configured to selectively turn-on or turn-off external magnetic field, to selectively attach/detach external items (such as the brush head 104) to the magnetic switchable device 702. The magnetic switchable device 702 may be configured to operate in a first mode and a second mode similar to the magnetic switchable device 214. The magnetic switchable device 702 may be actuated by the actuator 216.

[0052] In some aspects, the magnetic switchable device 702 may include a first side plate 704 and a second side plate 706, which may be disposed inside the handle 102. The first side plate 704 and the second side plate 706 may be made of ferrous material (e.g., steel, aluminum, brass, and/or the like), and may be disposed on the sides of the handle 102. The first side plate 704 and the second side plate 706 may be vertically attached to the handle 102 via any retaining mechanism such as adhesive.

[0053] The magnetic switchable device 702 may include a first magnet (e.g., a static magnet 708) and a second magnet (e.g., a rotating magnet 710). The static magnet 708 and the rotating magnet 710 may be positioned (or sandwiched) between the first side plate 704 and the second side plate 706. Each of the static magnet 708 and the rotating magnet 710 may contact the first side plate 704 and the second side plate 706, via side edges of the static magnet 708 and the rotating magnet 710. In some aspects, the static magnet 708 may be positioned above the rotating magnet 710. The static magnet 708 may be configured to contact the brush head 104 to magnetically couple with the brush head 104. The rotating magnet 710 may be configured to rotate at a predetermined range (e.g., 0 to 180 degrees) relative to the static magnet 708 to selectively turn-on or turn-off external magnetic field. The rotating magnet 710 may be configured to rotate via the actuator 216. In some aspects, the rotating magnet 710 may be mechanically coupled to the lever 602 described above. The rotation of the lever 602 causes the rotation of the rotating magnet 710.

[0054] Similar to the magnetic switchable device 214, when the north pole of the static magnet 708 is oriented to face the south pole of the rotating magnet 710, the magnetic flux emanating from the magnets 708, 710 may be present or stay enclosed within the magnetic switchable device 702, and may not move outside. In this position (e.g., a first position), the magnetic switchable device 702 may be in a demagnetized state or deactivated. Thus, the brush head 104 may not be attached to the handle 102 in the first position. To attach the brush head 104 to the handle 102, the user actuate the magnetic switchable device 702 to move the magnetic flux to the outside of the magnetic switchable device 702 (e.g., via the actuator 216). For example, the user may use the lever 602 to rotate the rotating magnet 710 clockwise or counter-clockwise to move the rotating magnet 710 to cause the magnetic switchable device 702 to move from the first position to a second position. In the second position, the north pole of the static magnet 708 may be oriented to face the north pole of the rotating magnet 710. In this position (i.e., the second position), the magnetic flux may not stay enclosed within the magnetic switchable device 702, and may move outside, thereby allowing the brush head 104 to attach to the handle 102. The user may move the magnetic switchable device 702 from the second position back to the first position, when the user desires to detach the brush head 104 from the handle 102.
