Description

Heater for cigarette type electronic cigarette device and cigarette type electronic cigarette device comprising same

Technical Field

The invention relates to a heater for a cigarette type electronic cigarette device and the cigarette type electronic cigarette device comprising the same.

Background

The electronic cigarette device generates an aerosol (aerosol) by heating or vaporizing a tobacco processing product, a tobacco extract, a nicotine-free liquid substance, or the like. Thus, when a user sucks the aerosol generated in the electronic cigarette device through the suction port (intake) of the electronic cigarette device while holding the electronic cigarette device, the aerosol can be discharged into the mouth of the user through the suction port.

As one of the ways, a cigarette-type electronic cigarette device of a fumigation method of heating a cigarette made of tobacco leaves has been developed. The cigarette type electronic cigarette device is a mode of heating cigarettes by a heater to generate steam for smoking. Therefore, the cigarette type electronic cigarette device has the following advantages: the problem of misuse of liquid-phase substances for liquid-phase electronic cigarette devices is solved, and a taste similar to that of existing cigarettes can be felt.

However, since the conventional cigarette-type electronic cigarette device uses a ceramic material as a heater, a large amount of electricity is consumed to maintain the temperature for heating the cigarette.

Thus, the conventional cigarette-type electronic cigarette device has a limitation that the battery life is very short.

Detailed Description

Hereinafter, embodiments of the present invention will be described in detail with reference to the accompanying drawings so that those skilled in the art to which the present invention pertains can easily carry out the embodiments. The present invention can be embodied in various different forms and is not limited to the embodiments described herein. In the drawings, portions that are not related to the description are omitted for the sake of clarity, and the same reference numerals are given to the same or similar components throughout the specification.

As shown in fig. 10, the

heater

100, 200, 300, 400, 500 for a cigarette-type electronic cigarette device according to an embodiment of the present invention may be provided on the insertion port 20 side of the cigarette-type electronic cigarette device into which the cigarette 10 is inserted, and may receive power from the cigarette-type electronic cigarette device.

Therefore, in a state where the cigarette 10 is inserted into the insertion port 20, if electricity is applied to the

heater

100, 200, 300, 400, 500 for the cigarette-type electronic cigarette device, the

heater

100, 200, 300, 400, 500 for the cigarette-type electronic cigarette device according to the embodiment of the present invention can generate heat to heat the cigarette 10.

Thus, the steam for smoking can be generated from the cigarette 10, and the user can inhale the steam generated from the cigarette 10 to smoke.

In this case, if a part of the total length of the cigarette 10 is inserted into the insertion port 20, the part of the cigarette 10 inserted into the insertion port 20 can be inserted into the

heater

100, 200, 300, 400, 500 for a cigarette-type electronic cigarette device according to an embodiment of the present invention.

Accordingly, the peripheral surface of a part of the cigarette 10 inserted into the insertion port 20 can be heated by the

heater

100, 200, 300, 400, 500 for the cigarette-type electronic cigarette device.

Meanwhile, the

heater

100, 200, 300, 400, 500 for a cigarette-type electronic cigarette device according to an embodiment of the present invention may heat the cigarette 10 using heat generated by an induction heating method.

To this end, as shown in fig. 1 to 7, a

heater

100, 200, 300, 400 for a cigarette-type electronic cigarette device according to an embodiment of the present invention includes a

heating member

110, 210, a

heat insulating member

120, 220, and a coil member 130.

In the

heating members

110 and 210, when electricity is applied to the coil member 130, eddy current is generated due to electromagnetic induction caused by ac current flowing along the coil member 130, and heating can be performed by loss of the eddy current. Thus, the

heating members

110 and 210 can heat the cigarette 10 by heat generated by eddy current loss.

For this, the

heating members

110, 210 may be formed of an electric conductor so as to generate heat by loss of eddy current due to electromagnetic induction when electricity is applied.

Thus, the

heater

100, 200, 300, 400 for a cigarette-type electronic cigarette device according to an embodiment of the present invention can heat the peripheral surface of the cigarette 10 by an induction heating method due to an electromagnetic induction effect, thereby reducing power consumption during heating and increasing the time for heating the cigarette 10.

That is, the

heater

100, 200, 300, 400 for a cigarette-type electronic cigarette device according to an embodiment of the present invention can reduce the amount of power consumed to maintain a heating temperature at which a cigarette can be heated. Therefore, the battery charging cycle or the battery replacement cycle of the electronic cigarette device can be prolonged.

Electromagnetic induction heating is a method of heating by converting electric energy into thermal energy by electromagnetic induction, and is a heating method using joule heat generated when a material to be heated is used and a secondary current induced by electromagnetic induction flows through the material to be heated. Such electromagnetic induction heating is well known, and thus a detailed description will be omitted.

Meanwhile, the coil part 130 may be electrically connected to the electronic cigarette device body and may receive power from the electronic cigarette device body.

In this case, the

heating member

110 or 210 may be formed with a space for receiving the cigarette 10 inserted when the cigarette 10 is inserted into the insertion port 20, and the circumference of the cigarette 10 inserted into the space may be surrounded by the

heating member

110 or 210.

Accordingly, if a part of the total length of the cigarette 10 is inserted into the space formed by the

heating members

110 and 210 through the insertion port 20, the peripheral surface of the inserted part of the cigarette 10 may face the inner surfaces of the

heating members

110 and 210.

Thus, a part of the cigarette 10 inserted into the space surrounded by the

heating members

110 and 210 can be heated entirely in the peripheral direction, and the heating area can be increased.

Meanwhile, the entire periphery of a portion of the cigarette 10 inserted into the space surrounded by the

heating members

110 and 210 faces the inner surface of the

heating members

110 and 210, and thus the entire periphery can be uniformly heated.

As an example, as shown in fig. 2 to 5, the heating member 110 may be a hollow metal pipe made of a metal material. As a non-limiting example, the above metal material may be a ferrous metal such as SUS304, SUS430, stainless steel.

Thus, when a part of the length of the cigarette 10 is inserted through the insertion port 20, the inserted cigarette 10 can be inserted into the metal tube.

In this case, as shown in fig. 2 and 4, the heating member 110 may be disposed such that an outer surface thereof is in contact with an inner surface of the

heat insulating member

120 or 220, and the heating member 110 may be fixed to the inner surface of the

heat insulating member

120 or 220 by a snap-in method or a bonding method.

Alternatively, as shown in fig. 3 and 5, the heating member 110 may be disposed so that a predetermined gap S1 is formed between the outer surface of the metal pipe and the inner surface of the

heat insulating member

120, 220 facing each other.

Accordingly, an air layer may be formed in the gap S1, and the air layer existing in the gap S1 may prevent heat of the heating member 110 generated by induction heating when electricity is applied from being transferred to the outside.

Therefore, the heat generated by the induction heating in the heating member 110 can be concentrated on the side of the cigarette 10 inserted into the heating member 110, so that the cigarette 10 can be heated more efficiently and the heat can be prevented from being transferred to the user side.

In this case, the heating member 110 and the

heat insulating members

120 and 220 may be fixed to each other by the separate fixing member 150.

As another example, as shown in fig. 6 and 7, the heating member 210 may be a metal pattern formed on the inner surface of the

heat insulating member

120 or 220. As shown in fig. 8, the metal pattern has a predetermined width, and can be formed on the inner surface of the

heat insulating material

120 or 220 in a predetermined pattern. Thus, the area heated by the induction heating manner when electricity is applied can be concentrated on a relatively narrow area compared to the embodiment as described above, so that uniform heat generation can be achieved.

The metal pattern may be formed of a metal material such as Cu, Ni, or Cr, may be formed by gold plating or etching, or may be in the form of a metal member to which a thin plate is attached.

The

heat insulating members

120 and 220 may be disposed to surround the

heating members

110 and 210, and may prevent heat generated in the

heating members

110 and 210 by induction heating from being transferred to the outside.

For example, the

heat insulating members

120 and 220 may be made of a glass material or a polymer resin having insulation and heat resistance. As a non-limiting example, the

heat insulating members

120 and 220 may be formed of quartz, sapphire, glass, or the like.

Meanwhile, the

heat insulating members

120 and 220 may have heat resistance to prevent damage by heat generated in the

heating members

110 and 210, and may have insulation to prevent an electrical short circuit from occurring when electricity is applied to the coil member 130 wound around the outer circumference.

Accordingly, when power is applied, heat generated in the

heating members

110 and 210 by electromagnetic induction heating due to the magnetic field generated in the coil member 130 can be prevented from being moved to the outside through the

heat insulating members

120 and 220.

Therefore, the heat generated by the induction heating in the

heating members

110 and 210 can be concentrated on the side of the cigarette 10 inserted into the

heating members

110 and 210, so that the cigarette 10 can be heated more efficiently and the heat can be prevented from being transferred to the user side.

As an example, as shown in fig. 2, 3 and 6, the heat insulating member 120 may be a hollow pipe.

Accordingly, the

heating members

110 and 210 may be disposed inside the heat insulating member 120, and the coil member 130 may be wound along the outer surface of the heat insulating member 120 a plurality of times.

In addition, the heat insulating member 220 may be configured in a double pipe form to further improve heat insulation.

That is, as shown in fig. 4, 5 and 7, the heat insulating member 220 may include: a hollow first tube 221 having a predetermined diameter; and a second pipe 222 having a relatively larger diameter than the first pipe 221, wherein the second pipe 222 can be disposed to surround the first pipe 221.

In this case, the inner surface of the second pipe 222 may be disposed to be spaced apart from the outer surface of the first pipe 221 by a predetermined distance. Thus, a gap S2 may be formed between the first pipe 221 and the second pipe 222, and an air layer may be formed in the gap S2.

Accordingly, the heat insulating member 220 can achieve a double heat insulating effect by not only a heat insulating effect by a material itself but also a heat insulating effect by an air layer formed between the first pipe 221 and the second pipe 222.

Accordingly, the heat generated by the induction heating in the

heating members

110 and 210 can be more concentrated on the cigarette 10 side inserted into the

heating members

110 and 210, and the heat loss can be further reduced.

As shown in fig. 4 and 7, when the heat insulating member 220 is formed in a double pipe form, the first pipe 221 and the second pipe 222 may be integrally formed such that upper ends thereof are connected to lower ends thereof. Alternatively, as shown in fig. 5, the first pipe 221 and the second pipe 222 may be formed of two separate members, and may be fixed to each other by a separate fixing member 150.

In addition, in the case where the

heat insulating members

120 and 220 are formed of a glass material having insulating and heat resistance, the

heat insulating members

120 and 220 may further include glass beads B to further improve heat insulation. The glass beads B as described above may be hollow cells filled with air inside. Accordingly, the

heat insulating members

120 and 220 can further reduce the heat transfer rate by the glass beads B, thereby having more excellent heat insulating properties.

In addition, the

heater

100, 200, 300, 400 for a cigarette-type electronic cigarette device according to an embodiment of the present invention may further include a heat dissipation coating 140, which may improve a heat dissipation rate when the heating member 110, 21 generates heat.

The heat dissipation coating 140 as described above may be formed on one side of the

heating member

110, 210 exposed to the outside. That is, the heat dissipation coating 140 may be formed on one surface side facing the cigarette 10 inserted into the

heating member

110 or 210.

Accordingly, when electricity is applied, the heat generated in the

heating members

110 and 210 can be smoothly transferred to the cigarette 10 side through the heat-dissipating coating 140, so that the cigarette 10 can be heated in a faster time.

For example, the heat dissipation coating 140 may be a coating layer including a heat dissipation filler, and the heat dissipation coating 140 may be a ceramic nanocoating layer.

The heat radiating filler may be a filler having heat radiation and heat transfer properties. As a non-limiting example, the heat dissipation coating 140 may be in a form in which a carbon filler such as graphite or Carbon Nanotubes (CNTs) is mixed with a ceramic filler such as AlN, BN, MgO, alumina, or the like.

The heat dissipation coating 140 as described above can improve the temperature deviation of each position of the

heating parts

110 and 210 by the heat dissipation filler. Thus, the

heater

100, 200, 300, 400 for a cigarette-type electronic cigarette device of the present embodiment can uniformly heat or raise the temperature over the entire area facing the cigarette 10, and can raise the temperature to a target temperature in a short time.

In addition, as shown in fig. 9, the heater 500 for a cigarette-type electronic cigarette device according to an embodiment of the present invention may further include a shielding member 160 for shielding a magnetic field generated in the coil member 130.

The shield member 160 described above may be disposed so as to surround the coil member 130 of the

heater

100, 200, 300, 400 for a cigarette-type electronic cigarette device as described in detail with reference to fig. 1 to 8.

Accordingly, the magnetic field generated in the coil member 130 is shielded by the shielding member 160 and concentrated on the

heating members

110 and 210.

Accordingly, in the

heating members

110 and 210, eddy current can be generated more smoothly due to electromagnetic induction action of the alternating current flowing along the coil member 130.

The shielding member 160 may be made of a magnetic material to shield a magnetic field.

As an example, a known shield sheet including a ferrite sheet, a polymer sheet, a ribbon sheet of at least one of an amorphous alloy and a nanocrystalline alloy, or the like may be used as the shield member 160, but the material of the shield member 160 is not limited thereto, and any known material used as a shield material for shielding a magnetic field may be used.

The shielding member 160 may be a single-layer sheet, or may be a multi-layer sheet in which a plurality of sheets are stacked.

Meanwhile, the shielding sheet may be a shielding sheet having flexibility. As a non-limiting example, the shielding sheet may be a sheet formed by separating a plurality of blocks.

While one embodiment of the present invention has been described above, the concept of the present invention is not limited to the embodiments proposed in the present specification, and a person having ordinary skill in the art understanding the concept of the present invention can easily propose other embodiments by adding, changing, deleting, adding components, and the like within the scope of the same concept, and the present invention also falls within the scope of the concept of the present invention.
