## Abstract

Provided is a heater assembly for a cigarette-shaped electronic cigarette. A heater assembly for a cigarette-shaped electronic cigarette comprises a smoking vapor generation part including a first heater configured to generate smoking vapor by heating a portion of a cigarette inserted thereinto, a smoky vapor generation part including a second heater configured to generate smoky vapor by heating a liquid material when the cigarette is puffed on, and a supporting part to which each of the smoking vapor generation part and the smoky vapor generation part is coupled, wherein the supporting part includes a movement passage through which the smoky vapor generated in the smoky vapor generation part is moved to the smoking vapor generation part.

## Claims

### Claim 1

A heater assembly for a cigarette-shaped electronic cigarette, the heater assembly comprising:
a smoking vapor generation part including a first heater configured to generate smoking vapor by heating a portion of a cigarette inserted thereinto;
a smoky vapor generation part including a second heater configured to generate smoky vapor by heating a liquid material when the cigarette is puffed on; and
a supporting part to which each of the smoking vapor generation part and the smoky vapor generation part is coupled,
wherein the supporting part includes a movement passage through which the smoky vapor generated in the smoky vapor generation part is moved to the smoking vapor generation part.

### Claim 2 (depends on 1)

The heater assembly of claim 1, wherein the smoking vapor generation part includes:
the first heater;
a heat insulating member wound one or more times to surround an outer surface of the first heater in a circumferential direction of the first heater; and,
a fixing member formed to have a hollow form to surround the heat insulating member and configured to surround and fix the heat insulating member such that the heat insulating member is maintained in a state of being pressed against the outer surface of the first heater.

### Claim 3 (depends on 2)

The heater assembly of claim 2, wherein a first cover member is disposed outside the fixing member; and
a gap is formed between an inner surface of the first cover member and an outer surface of the fixing member, which face each other, in a height direction of the fixing member.

### Claim 4 (depends on 1)

The heater assembly of claim 1, wherein the supporting part includes a protrusion in a hollow form which protrudes in one direction and to which the smoky vapor generation part is coupled, and
a communication passage is formed in a bottom surface of the protrusion and connected to the movement passage.

### Claim 5 (depends on 1)

The heater assembly of claim 1, wherein the smoky vapor generation part is detachably coupled to the supporting part.

### Claim 6 (depends on 1)

The heater assembly of claim 1, wherein an accommodation groove is formed in one surface of the supporting part to accommodate a circuit board, and the circuit board is electrically connected to the first heater.

### Claim 7 (depends on 1)

The heater assembly of claim 1, wherein the first heater is formed to have a hollow cylindrical shape of which upper and lower portions are open such that the portion of the cigarette is inserted thereinto, and the first heater heats an outer surface of the cigarette.

### Claim 8 (depends on 7)

The heater assembly of claim 7, wherein the first heater includes:
a support made of a ceramic material and formed to have a hollow form;
an electrode pattern patterned on one surface of the support to generate heat; and
a protective layer having an insulating property and a heat insulating property and covering the electrode pattern.

### Claim 9 (depends on 2)

The heater assembly of claim 2, wherein the heat insulating member includes a graphite material to reduce heat generated in the first heater from being dissipated in a radial direction of the first heater.

### Claim 10 (depends on 1)

The heater assembly of claim 1, wherein the smoky vapor generation part includes:
a body having an air passage formed in a length direction thereof such that outside air passes through the air passage;
a coupling member coupled to the body;
a second cover member coupled to the coupling member to form a storage space in which the liquid material is accommodated in a certain amount;
an absorption member disposed in the air passage to absorb the liquid material introduced from the storage space; and
a second heater wound a plurality of times in a length direction of the absorption member to generate the smoky vapor by vaporizing the liquid material absorbed by the absorption member when power is applied.

### Claim 11 (depends on 1)

A cigarette-shaped electronic cigarette comprising:
the heater assembly of claim 1;
a case which has an inlet for inserting the cigarette in a region corresponding to the smoking vapor generation part and in which the heater assembly is embedded;
a control part disposed inside the case to control an overall operation of the heater assembly; and
a power supply part configured to supply driving power to the control part.

### Claim 12 (depends on 11)

The cigarette-shaped electronic cigarette of claim 11, wherein the case includes a cover member configured to open or close the inlet.

### Claim 13 (depends on 11)

The cigarette-shaped electronic cigarette of claim 11, wherein a charging port configured to recharge power of the power supply part is provided at one side of the case.
