Description

Liquid cartridge assembly for fine particle generator {LIQUID CATRIDGE ASSEMBLY FOR MICRO PARTICLE GENERATOR}

The present invention relates to a liquid cartridge assembly for a fine particle generating device.

In the case of a conventional cigarette-inserted electronic cigarette, the tobacco leaf is steamed and inhaled, so it does not emit much smoke compared to the combustion type cigarette, so the user feels less or is not satisfied with smoking, or remains in the heater. There was a problem with frequent cleaning because there was a lot of water left.

To solve this problem, there is a need to develop an electronic cigarette that can improve the inhalation amount of cigarette vapor.

1 is a view showing an example of a fine particle generating device capable of using a liquid and a cigarette in parallel according to the prior art. A fine particle generator having a liquid cartridge according to the prior art includes a main body 10 and a liquid cartridge assembly 20 detachable to the main body 10, and covers the main body 10 and the liquid cartridge assembly 20. It includes upper and lower casings 31 and 32 forming the exterior.

In the main body 10, components such as a battery, a main circuit board, and a button are disposed in the lower part 11, and a smoking part 12 for smoking a cigarette T is disposed in the upper part. The size of the smoking part 12 is smaller than the size of the lower part 11 of the main body, and a free space is provided on one side. The liquid cartridge assembly 20 is coupled to this free space.

The smoking part 12 includes a cylindrical receiving part 12 with an open top so that a cigarette can be inserted, and a cylindrical heater disposed on the inner circumference of the receiving part 12 and heating the cigarette T.

An auxiliary circuit board connected to the main circuit board is disposed on the upper surface of the lower part 11 to transmit a control signal to the liquid cartridge assembly 20, and a spring terminal 12a is connected to the upper side of the auxiliary circuit board. The terminal of the liquid cartridge assembly 20 is in contact with the spring terminal 12a connected to the auxiliary circuit board to supply power and electric signals to the liquid cartridge assembly 20.

In addition, the smoking part 12 may communicate with the liquid cartridge assembly 20 to be described later through an airflow path 12b. However, in the conventional liquid cartridge assembly, the airflow path is bent in an L-shape, so that airflow resistance is generated, and thus there is a limit to increase the amount of atomization. In addition, since the installation structure of the wick and the coil was complicated, the assembly process took a lot of time and cost. Accordingly, there is a need for improvement in the airflow path and wick installation structure of the liquid cartridge assembly.

2 is a cross-sectional view of a liquid cartridge assembly according to the prior art. The liquid cartridge assembly for a fine particle generating device provided by the present invention includes an upper case 41 as a case forming an exterior, a case 42 at the lower portion, and an inner lower case 44 installed in the lower case 42 do. A liquid storage space is formed in the upper case 41, and a plate 43 is installed between the upper case 41 and the lower case 42, so that the liquid stored in the upper case 41 is transferred to the inner lower case 44. Let it flow slowly. The inner lower case 44 has a hole 47 formed on one side thereof to allow outside air to be introduced therein. A coil block in which the heating coil 46 is wound around the wick 45 is fixed to the inner lower case 44. The center of the heating coil 46 is wound around the wick 45 and both ends are drawn out to the lower surface of the inner lower case 44 and fixed between the inner lower case 44 and the lower case 42. The pin-shaped terminal 48 penetrating the lower surface of the lower case 42 contacts the heating coil 46 drawn out to the lower surface of the lower case 42 and applies current to the heating coil 46.

Conventionally, fine particles were generated by being wetted in a liquid phase in the wick 45 made of cotton or glass fiber, but there was a problem that the liquid phases wetted in the wick 45 due to vibration or impact were separated, causing leakage.

In addition, the existing wick 45 made of cotton or fiberglass is distorted during assembly.

As a result, it became the cause of the deviation in the amount of fine particles generated by eccentricity or assembly deviation.

Let it flow. A coil block in which the heating coil 320 is wound on the liquid absorption medium 310 is fixed to the inner lower case 130. The center of the heating coil 320 is wound around the liquid absorption medium 310 and both ends are drawn out to the lower surface of the inner lower case 130 and fixed between the inner lower case 130 and the lower case 120.
