[60] Referring to FIGS. 1 to 9, the heating applicator according to the present invention includes applicators 10, 20, 30, and 40 that are installed on a front end portion of a knob to give their corresponding cosmetic functions, and heating units that are added to the applicators 10, 20, 30, and 40 to allow the applicators 10, 20, 30, and 40 to have a heating function.

[61] Referring to FIG. 1, the heating applicator 10 of the heating applicator according to the first embodiment of the present invention is an integrated brush obtained by twisting two strands of wires 12 in a spiral shape, with putting a brush bristle 11 having a predetermined length between the wires 12, and the heating unit corresponding thereto includes a hot wire 13 that is wound in a spiral shape according to the spiral of the wires 12, a power supply 14 that is connected electrically to the hot wire 13 in order to supply power to the hot wire 13 to be heated, and a circuit board 15 that is interposed between the hot wire 13 and the power supply 14 to have a switch device controlling the supply or block of the power of the power supply 14.

[62] With the heating applicator according to the first embodiment of the present invention according to the constitution as described above, if power in the power supply 14 is applied to the hot wire 13 as a user turns on the switch device (not shown) of the circuit board, the hot wire 13 is heated to cause heat conductivity to the wire and brush bristle 11, thereby finally heating the brush bristle 11.

[63] A make-up can be performed through the brush bristle 11 heated as described, and if the make-up is completed, the switch device of the circuit board 15 is turned off, thereby releasing a heating function.

[64] As shown in FIGS. 2 to 5, the applicator 20 of the heating applicator according to a second embodiment of the present invention is a comb-brush assembly wherein a comb 21 and a brush 22 are assembled, and a heating unit corresponding thereto where the comb 21 becomes a heatable heater includes a power supply 23 that is electrically connected to the comb 21 in order to supply power to the comb 21 to be heated, and a circuit board 24 that is interposed between the comb and the power supply 23 to have a switch device controlling the supply or block of the power.

[65] Herein, the comb 21 may be made of metal material or heating plastic material so that it can be spontaneously heated according to the application of power, or the comb 21 may be applied with a structure where a plating layer 25 is formed on the comb 21 made of general plastic material or a hot wire 26 is integrally wound.

[66] The brush 22 has a structure where a plurality of brush bristles 22a having a predetermined length are longitudinally interposed between wires 22b whose central portions are bent and overlapped to twist the wires 22b in a spiral form at a predetermined frequency, thereby allowing the brush bristles 22a to be fixed radially against a wire axis. The comb 21 corresponding thereto includes a wall body 21b formed with a plurality of teeth of comb 21a, a penetrating pipe body 21c fixed to a lower end portion of the wall body 21 in a state where the brush 22 is penetrated therethrough, and a supporting groove 2 Id that insertedly supporting a upper end portion of the brush 22 to an upper end portion of the wall body 21b.

[67] Herein, the teeth of comb 21a has one serial structure where they are vertically arranged, wherein the serial structure may be variously constituted, such as two columns or three columns other than one column.

[68] With the heating applicator according to the second embodiment constituted as above, the brush 22 penetrates through the penetrating pipe body 21c of the comb 21 so that its upper end portion is insertedly fixed to the supporting groove 2 Id of the comb 21 to be coupled to each other, and then if the power of the power supply 23 is applied to the comb 21 that is the heater as a user turns on the switch device (not shown) of the circuit board 24, the comb 21 is heated and heat conductivity is generated to the brush 22, thereby finally heating the brush bristles 22a.

[69] At this time, the comb 21 and the brush bristles 22a have different dual temperatures, such that the make-up can be performed through the comb 21 and the brush bristles 221 heated as above and if the make-up is completed, the heating function can be released by turning off the switch device of the circuit board 24.

[70] As shown in FIGS. 6 to 8, the applicator 30 of the heating applicator according to a third embodiment of the present invention is formed in one body that performs a predetermined cosmetic function. A heating unit that corresponding thereto where the applicator formed in one body becomes a heatable heater includes a power supply 31 that is connected electrically to the applicator in order to supply power to the applicator 30 to be heated, and a circuit board 32 that is interposed between the applicator 30 and the power supply 31 to have a switch device controlling the supply and block of power.

[71] Herein, the applicator 30 may be made of metal material or heating plastic material so that it can be spontaneously heated according to the application of power, or the applicator 30 may be applied with a structure where a plating layer 25 is formed on the applicator 30 made of general plastic material or a space part 30a is formed inside the applicator 30 made of general plastic material and a circuit board 34 having a switch device is built in the space part 30a to wind a heating coil 35 on an outer circumferential surface of the circuit board 34 to be heated.

[72] The applicator may be formed in the manner where the entirety of its main body in a cylinder shape is covered by teeth of comb 30b through a (micro) injection molding or may be formed in a manner where the entirety of its main body in a cylinder shape is covered by brush bristles 30c.

[73] The present invention describes one embodiment wherein the applicator 30 is formed in the manner where the plurality of teeth of comb 30b and the brush bristles 30c are combined in the main body in the cylinder shape through the (micro) injection molding.

[74] The brush bristles 30c formed by the injection molding is formed in an injection- molded cone shape to be extended radially from the outer circumferential surface of the main body.

[75] Herein, the teeth of comb 30b has one serial structure where they are vertically arranged along the outer circumferential surface of the applicator 30, wherein the serial structure may be variously constituted, such as two columns or three columns other than one column.

[76] With the heating applicator according to the third embodiment constituted as above, if the power of the power supply 31 is applied to the comb 21 that is the heater as a user turns on the switch device (not shown) of the circuit board 32, heat conductivity is generated to the teeth of comb 30b and the brush bristles 30c of the applicator 30, thereby finally heating the entirety thereof.

[77] The make-up can be performed through the teeth of comb 30b and the brush bristles

30c heated with a single temperature as described, and the heating function can be released by turning off the switch device of the circuit board 32 if the make-up is completed.

[78] Meanwhile, as shown in FIG. 8, a space part 30a may be formed inside the general plastic material and a circuit board 34 having a switch device may be built-in the space part 30a to wind a heating coil 35 on an outer circumferential surface of the circuit board 34 and to apply power, thereby being heated.

[79] At this time, the heat generated from the heating coil 35 is transferred to the teeth of comb and the brush bristles of the main body through a convection process, thereby heating them.

[80] As shown in FIG. 9, the applicator 40 of the heating applicator according to a fourth embodiment of the present invention is formed in one body having teeth of comb 41 by a double injection and brush bristles 42. A heating unit corresponding thereto where the teeth of comb 41 become heatable heaters includes a power supply 41 that is connected electrically to the teeth of comb in order to supply power to the teeth of comb to be heated, and a circuit board 44 that is interposed between the teeth of comb 41 and the power supply 43 to have a switch device controlling the supply and block of power.

[81] Herein, the teeth of comb 41 may be made of metal material or heating plastic material so that they can be spontaneously heated according to the application of power.

[82] Although not shown, as shown in the third embodiment, the teeth of comb 41 may also be formed in a structure where a plating layer is formed on the teeth of comb 41 made of general plastic material to be heated.

[83] The brush bristles 42 are formed in an injection molded cone shape to be extended radially from the outer circumferential surface of the main body.

[84] Herein, the teeth of comb 41 is formed on serial structure where they are arranged vertically along the outer circumferential surface of the applicator 40, wherein the serial structure may be variously constituted, such as two columns or three columns other than one column.

[85] Herein, the double injection will be described in brief.

[86] The applicator 40 according to the fourth embodiment of the present invention forms the teeth of comb 41 in a shape having a plurality of cylindrical projections and the brush bristles 42 in a cone shape, wherein the teeth of comb 41 are formed in one body integrally with a rod 43 of the applicator 40 through a primary injection molding, and the brush bristles 42 are subject to a secondary injection molding using material different from that of the teeth of comb 41.

[87] An injection method using different material as described above is referred to as a double injection. Herein, describing the double injection in more detail, it is a method to fill a space between a primary molded product that is originally molded and a secondary cavity with secondary resin through two injection apparatuses, an injector having a structure where a rotation equipment is installed on a operating plate, or a molding designed to enable to perform a double injection using a core or sliding structure using two different resins or resins having two different colors.

[88] With the double injection as described above, the cavity on the primary side and that on the secondary side are exactly replaced to have little limitation in form and the product is widely applied to have diversity in design. Further, since the injection is made at one time, it solves, through the molding at one time, the feature of the general injection in the related art that a product is made by molding two components twice and performing a secondary process such as a welding or painting process, making it possible to produce products in various designs as well as to reduce costs.

[89] With the heating applicator according to the fourth embodiment of the present invention, if the power of the power supply 43 is applied to the teeth of comb 41 that is the heater as a user turns on the switch device (not shown) of the circuit board 44, the teeth of comb 41 is heated and heat conductivity is generally generated to the brush bristles 42, thereby finally heating the entirety thereof at a dual temperature.

[90] The make-up can be performed through the teeth of comb 41 and the brush bristles

42 heated at a dual temperature as described above, and the heating function can be released by turning off the switch device of the circuit board 44 if the make-up is completed. [91] Meanwhile, it would be preferable that a boosting circuit (not shown) is further included in the circuit boards 15, 24, 32 and 44 having the switch devices in the entire embodiments, the boosting circuit that rapidly raises a temperature when power is applied to the corresponding applicators 10, 20, 30, and 40.
