Cartridge and non-combustion type suction device

1 . A cartridge which is used in a non-combustion type suction device having a suction port, the cartridge comprising:

a tank having a liquid storage in which a liquid is storable;

a heater to which the liquid in the liquid storage is supplied and configured to heat the liquid; and

an atomizing container configured to support the heater, the atomizing container including a liquid holder and at least one liquid guide extending from the liquid holder to the heater, the liquid holder being configured to hold the liquid, the liquid holder being provided apart from the heater, and the at least one liquid guide configured to recirculate the liquid held in the liquid holder to the heater,

wherein the liquid holder is not in contact with the heater.

2 . The cartridge according to claim 1 , wherein the liquid storage is provided apart from the liquid holder and the at least one liquid guide.

3 . The cartridge according to claim 1 , wherein the liquid holder and the at least one liquid guide are arranged in a circumferential direction of the cartridge when viewed from an axial direction of the cartridge,

wherein the tank is disposed on a side of the suction port with respect to the heater in the axial direction, and

wherein the atomizing container is disposed on a side opposite to the suction port with respect to the heater in the axial direction.

4 . The cartridge according to claim 3 , wherein the at least one liquid guide is two liquid guides, and

wherein the two liquid guides are disposed at two locations facing each other in a radial direction of the cartridge when viewed from the axial direction.

5 . The cartridge according to claim 4 , wherein the liquid holder is disposed to abut on both sides of the at least one liquid guide when viewed from the axial direction.

6 . The cartridge according to claim 3 , wherein the liquid holder is disposed to abut on both sides of the at least one liquid guide when viewed from the axial direction.

7 . The cartridge according to claim 3 , wherein the atomizing container includes:

an outer tube configured to support both end portions of the heater, and

an inner tube provided inside the outer tube,

wherein the at least one liquid guide is a gap formed between an inner peripheral surface of the outer tube and an outer peripheral surface of the inner tube.

8 . The cartridge according to claim 7 , wherein the liquid holder is a space formed between the inner peripheral surface of the outer tube and the outer peripheral surface of the inner tube, and

wherein a distance between the inner peripheral surface of the outer tube and the outer peripheral surface of the inner tube is larger in the liquid holder than in the at least one liquid guide.

9 . The cartridge according to claim 8 , wherein when viewed from the axial direction, the distance becomes smaller as the space of the liquid holder approaches the at least one liquid guide.

10 . The cartridge according to claim 7 , wherein the outer tube has a first support surface configured to support the heater,

wherein the inner tube has a second support surface configured to support the heater, and

wherein at least a portion of the first support surface and the second support surface have same level surfaces.

11 . The cartridge according to claim 10 , wherein the heater has a columnar shape, and

wherein the first support surface and the second support surface abut on an outer peripheral surface of the heater.

12 . The cartridge according to claim 11 , wherein the first support surface extends to a side of the heater.

13 . The cartridge according to claim 10 , wherein the at least one liquid guide recirculates the liquid to the heater through the gap between the first support surface and the second support surface.

14 . The cartridge according to claim 10 , wherein the heater includes:

a columnar portion having a liquid absorbing property, and

a heating wire configured to surround a middle portion of the columnar portion,

wherein the second support surface extends to a vicinity of the heating wire.

15 . The cartridge according to claim 10 , wherein the heater has a flat surface, and

wherein the first support surface and the second support surface abut on the flat surface.

16 . The cartridge according to claim 15 , wherein the heater has a heating wire on the flat surface.

17 . A non-combustion type suction device comprising the cartridge according to claim 1 .

18 . The cartridge according to claim 1 , wherein the heater includes:

a liquid absorbing portion having a liquid absorbing property; and

a heating wire configured to heat the liquid absorbing portion,

wherein the liquid absorbing portion is in contact with the at least one liquid guide.

19 . A non-combustion type suction device comprising the cartridge according to claim 18 .

20 . The cartridge according to claim 1 , wherein the heater comprises a wick and a heating coil surrounding the wick.
