Hereinafter, embodiments of the present invention will be described in detail with reference to FIGS. 1 to 5.

1 to 3 are views for explaining a portable heating tumbler according to an embodiment of the present invention.

1 to 3, a portable heating tumbler according to an embodiment of the present invention includes a body part 100, a cover part 110, a display part 120, a temperature setting part 180, and a heating part 140. , A temperature sensor 130 and a control unit 200 may be included.

Specifically, the body portion 100 may have a space for the contents of the tumbler. The body portion 100 is formed to be hollow by opening the top. The body portion 100 may be formed of metal or plastic. The inside of the body portion 100 may be formed of a metal material, and the outside of the body portion 100 may be formed of a non-metal material such as plastic.

The cover part 110 may be coupled to seal the open upper part of the body part 100. The cover part 110 may be screwed with the body part 100. In this case, a thread is formed in the body part 100, and a screw groove is formed in the cover part 110 so that the screw thread and the screw groove rotate the cover part 110 to seal the body part 100.

A display unit 120 may be formed on the cover unit 110 to display information by being exposed to the outside.

The display unit 120 may display the temperature of the contents in the tumbler device, and may display information such as an operating state (heating or keeping warm). Since the display unit 120 is installed above the cover unit 110, there is an advantage in that the user can intuitively check information such as the temperature and operation status of the contents.

The heating part 140 is formed under the body part 100 to supply heat to the contents. The heating unit 140 may be a linear heating element or a planar heating element made of a heating wire or carbon fiber. The heating part 140 may have a linear heating element formed of carbon fibers as a thread, and formed in a concentric circle shape under the body part 100. In addition, the heating unit 140 may be formed in a film form. That is, the heating part 140 may be formed under the body part 100 by forming a composition including carbon fiber in the form of a film.

Meanwhile, the heating unit 140 may use a carbon fiber heating element in which graphene is coated on carbon fiber. The carbon fiber heating element may include a carbon fiber layer including a plurality of carbon fibers, graphene coated on the carbon fiber layer, and at least one metal electrode attached to one surface of the carbon fiber layer coated with graphene.

At this time, the graphene-coated carbon fiber layer includes at least one impregnated region impregnated with a conductive adhesive that attaches at least one gold metal electrode to one surface of the graphene-coated carbon fiber layer.

The graphene-coated carbon fiber layer acting as a heating part and the metal electrode acting as an electrode part each have different specific resistances, and a voltage drop phenomenon in which the applied voltage decreases due to the difference in resistance appears, and the unit at the contact surface The heat generation concentration phenomenon may occur due to the high calorific value per area, but the heat concentration phenomenon is eliminated by the conductive adhesive in the impregnated region of the carbon fiber layer coated with graphene. At this time, it is preferable that the specific resistance of the conductive adhesive is lower than that of the carbon fiber layer coated with graphene and higher than that of the metal electrode.

The conductive adhesive is impregnated into the inside of the carbon fiber layer coated with graphene to coat the surface of the carbon fiber and attach the coated surface to one surface of the metal electrode, thereby forming a form capable of passing the voltage applied through the metal electrode. Accordingly, the intermediate resistance zone is formed between the resistance of the metal electrode, which is the electrode part, and the resistance of the carbon fiber layer, which is the heating part, thereby minimizing the concentration of heat generated by the sudden voltage drop. That is, in the carbon fiber layer coated with graphene, the electrical resistance of the impregnated region is lower than that of the non-impregnated region excluding the impregnated region, and the electric resistance of the metal electrode is lower than that of the impregnated region.

The carbon fiber layer serves as a heating part. The carbon fiber layer may be formed of a bundle or sheet of carbon fibers. Carbon fibers may be PAN-based (polyacrylonitrile-based), pitch-based, rayon-based, as well as fibrous carbon-containing materials. These carbon fibers may have a one-dimensionally elongated structure, and there is no particular limitation on the fiber length of the carbon fibers.

For example, the carbon fiber sheet may be a carbon fiber nonwoven fabric manufactured by adding a binder using a chopped carbon fiber cut into a length of about 1 to 30 mm in the form of a nonwoven fabric, and using a wet device.

At this time, the binder includes a urethane group, an epoxy group, a carboxyl group, a carbonyl group, an acrylic group, a hydroxy group, an ester group, an ether group, a vinyl acetate group, an amide group, an imide group, and a maleic acid group represented by polyvinylidene fluoride (PVdF). Organic binders or aqueous binders such as polyvinylpyrrolidone (PVP), polytetrafluoroethylene (PTEE), styrene butadiene rubber (SBR), carboxymethylcellulose (CMC) and polyvinyl alcohol (PVA) are selected according to the manufacturing purpose. And the content can be determined in consideration of the content of the carbon fiber used and the thickness and conductivity of the carbon fiber sheet to be manufactured. At this time, cellulose, curdran, tamarid, gelatin, guar gum, pectin, LBG, carrageenan, konjac, alginic acid, arabic, gellan, xanthan, etc. can be added and used for the purpose of improving the viscosity to increase dispersion stability.

Graphene is used to compensate for the carbon fiber, since the dense portion with relatively high density and the dense portion with low density are arbitrarily formed in the process. Graphene may be formed of graphene (GO) in an oxide state, graphene (GP), and graphene (RFO) in a reduced state of graphene oxide (GO). Graphene can be used in the form of a thin film or a liquid. Graphene has a surface area of 10~3,000㎡/g, and its elastic modulus is 800~tensile strength is 100~GPa.

The metal electrode may be a metal including at least one of copper, aluminum, silver, nickel, and tin.

The impregnated region is formed by impregnating a conductive adhesive to the inside of the graphene-coated carbon fiber layer, and is attached to one surface of the metal electrode. In the case of a conductive adhesive that is impregnated with a carbon fiber layer coated with graphene as a heating part and adhered to a metal electrode as an electrode part, it is an adhesive containing a conductive filler formulated to have a specific resistance level higher than that of the metal electrode and lower than that of the carbon fiber layer. Specifically, depending on the density, thickness, and porosity of the graphene-coated carbon fiber layer in the form of a nonwoven fabric, felt, sheet, etc., a level of 10 to a level capable of sufficiently impregnating the inside of the graphene-coated carbon fiber layer Conductive adhesives with a viscosity of 15,000 cps can be used.

Here, the conductive adhesive impregnated in a partial region of the carbon fiber layer coated with graphene may include 1 to 85% by weight of a solvent, 0.1 to 15% by weight of a polymer binder, and 1 to 55% by weight of a conductive filler. The amount of each composition can be used to suit the purpose, such as viscosity, taking into account the resistance of the graphene-coated carbon fiber layer and the metal electrode, the range of the specific resistance of the conductive adhesive, and the density and porosity of the graphene-coated carbon fiber layer. have. In the case of a polymer binder, at least one selected from acrylate resin, epoxy resin, polyester, polyurethane, polycarbonate, polyamide, polyimide, and polyether may be included. In addition, as the conductive filler, carbon nanotubes, carbon black, pulverized carbon fibers, and metal powders such as gold, silver, copper, and the like may be used. In addition, organic solvents such as water, alcohol, acetone, N-methylpyrrolidone (NMP), ethylene glycol, propylene glycol, and glycerin may be used as the solvent.

In addition, for excellent electrical performance and high impregnation rate, a single-walled or multi-walled carbon nanotube may be mixed with a conductive adhesive. Specifically, the conductive adhesive may further include 1 to 83% of carbon nanotubes. For example, the appropriate mixing amount of the carbon nanotubes may be 7% by weight or more of the solid content after drying the conductive adhesive solution at 250 degrees.

The temperature setting part 180 may be formed on the cover part 110 or may be formed on the body part 100. The temperature setting unit 180 may detect the amount of rotation of the cover unit 110 and increase the temperature of the heating unit 140 according to the sensed amount of rotation. For example, the temperature setting unit 180 may detect a rotation amount that rotates after the cover unit 110 is immersed in the body unit 100 to set a temperature value corresponding to the rotation amount.

The set temperature according to the rotation amount of the temperature setting unit 180 is displayed on the display unit 120 described above, so that the user may set the temperature while adjusting the rotation amount.

Meanwhile, the temperature setting unit 180 may be set to be reset to 0 degrees when the cover unit 110 and the body unit 100 are unlocked.

The portable heating tumbler according to an embodiment of the present invention may further include a temperature sensor 130 formed in the body part 100.

The temperature sensor 130 may measure the temperature of the contents contained in the body part 100 for a set time (for example, within a few seconds) and provide it to the control unit 200 or the display unit 120. The temperature information provided by the temperature sensor 130 is displayed on the display unit 120 in real time, so that the user can check the temperature of the contents.

In addition, the temperature information provided to the control unit 200 may be displayed on the display unit 120 by allowing the control unit 200 to calculate the remaining time until the set temperature of the contents.

The portable heating tumbler according to an embodiment of the present invention may further include a capacity measuring sensor that measures the capacity of the contents.

The capacity measurement sensor may include an optical sensor, an electrostatic sensor, a weight sensor, etc. formed in the body part 100 to measure the weight or capacity of the contents, and provide the measured value to the control unit 200 or the display unit 120 .

The control unit 200 may control the temperature of the heating unit 140. When the temperature information set by the temperature setting unit 180 is received, the controller 200 calculates a required amount of power corresponding to the temperature information, and controls the calculated amount of power to be supplied.

For example, the controller 200 may perform on/off control of a portable battery connected by a cable. In the embodiment of the present invention, the use of a portable battery has been described as an example, but in addition to the portable battery, a car cigar jack or a household outlet may be used. To this end, the body portion 100 may be provided with a USB port 150, a cigar jack port, a household power cable port, etc. to be connected to the heating portion 140 at the bottom.

The control unit 200 may provide the amount consumed by the user for one day to the display unit 120 by using information provided from the capacity measurement sensor 210.

In addition, the control unit 200 calculates the amount of heat required up to the set temperature through the capacity of the contents provided from the capacity measurement sensor 210, and provides the remaining time for reaching the temperature of the contents to the set temperature to the display unit 120. I can.

As described above, the portable heating tumbler according to an embodiment of the present invention can easily boil or heat contents such as water or milk powder outdoors using a portable battery.

In addition, in the portable heating tumbler according to an embodiment of the present invention, the user can intuitively and easily select warmth or boiling water by freely adjusting the temperature.

Meanwhile, in the portable heating tumbler according to an embodiment of the present invention, the body portion 100 may be separated.

As shown in Figure 4, the body portion 100 may be separated and combined into the first to third containers (102, 104, 106). At this time, the first to third containers 102, 104, and 106 are screwed together to improve watertightness. The first to third containers 102, 104, and 106 may be coupled by fitting in addition to the screw coupling method as described above.

By separating the body portion 100 into the first to third containers 102, 104, and 106, the user can facilitate cleaning.

In FIG. 4, it has been described for example that the body portion 100 is divided into three containers 102, 104, and 106, but it may be divided into two. That is, only two containers may be used, and may be separated into several depending on the capacity of the contents.

In addition, the portable heating tumbler according to an embodiment of the present invention may further include a mixer for mixing powdered milk or a solution.

As shown in FIG. 5, when the powdered milk or powder is mixed with water or the like, the mixer unit 160 can shorten the mixing time and prevent the occurrence of sediment on the floor.

The mixer unit 160 is preferably formed on the bottom of the body unit 100, but the configuration of the mixer unit 160 may lower the heat transfer efficiency supplied from the heating unit 140. Accordingly, the mixer unit 160 may be formed on the cover unit 110.

For example, the mixer unit 160 is formed on the cover unit 110, and rotates the rotating blade 170 through a motor or rotating means. In this case, the shape and length of the rotating blade 170 may be determined according to a user's selection.

Here, the mixer unit 160 may use a manual winding method other than a motor. That is, in the case of a motor, separate energy is required, but when the manual winding method is used, the user rotates the cover unit 110 and the rotational force is accumulated to rotate the internal winding in the opposite direction to operate the rotating blade.

In this way, the mixer unit 160 rotates with the non-power of the rotating blade 170 and does not use separate energy, so that the power of the portable battery connected to the portable heating tumbler can be fully used for the heating unit 140.

In particular, in the case of a portable tumbler, it is necessary to rely on the power of the battery, and thus there is a need to prevent the use of power by other devices. Therefore, it is preferable that the mixer unit 160 is installed on the cover unit 110, and a manual winding method is more preferable.

As described above, the portable heating tumbler according to the embodiment of the present invention has a mixer unit so that powdered milk or powdered additives can be easily dissolved in a solution, as well as preventing sedimentation, and rotating the blade without power. By operating, the power of the portable battery can be completely supplied to the heating unit.

The above description of the present invention is for illustrative purposes only, and those of ordinary skill in the art to which the present invention pertains will be able to understand that other specific forms can be easily modified without changing the technical spirit or essential features of the present invention. will be. Therefore, it should be understood that the embodiments described above are illustrative in all respects and are not limiting. For example, each component described as a single type may be implemented in a distributed manner, and similarly, components described as being distributed may also be implemented in a combined form.

The scope of the present invention is indicated by the claims to be described later, and all changes or modified forms derived from the meaning and scope of the claims and their equivalent concepts should be construed as being included in the scope of the present invention.
