Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of steam type electronic cigarette, in particular to a cartridge for steam type electronic cigarette, and further relates to an electronic cigarette system used in cooperation with the cartridge. BACKGROUND

[0002] The existing steam type electronic cigarette (i.e. aerosol atomization system) is a nicotine delivery system for consumers to smoke by heating the electronic cigarette atomization material to generate a vaporization reaction to produce aerosol. This type of electronic cigarette system generally adopts the basic structure of a traditional atomization core matched with an oil tank, and uses the atomization core to heat the electronic cigarette atomization material to generate aerosol for consumers to smoke. Since the oil-like electronic cigarette atomization material is directly connected to the suction channel, this type of electronic cigarette system is not a strictly sealed system, and the electronic cigarette atomization material will penetrate into the suction channel through the oil guide cotton in the system, thus there is always a problem of oil leakage, which seriously hinders the development of the industry and affects the product quality.

[0003] In order to solve the problem of leakage of liquid electronic cigarette atomization material, the Chinese utility model patent application CN2024112435296 discloses a new cartridge, the structure of which includes a tubular shell (1), a lower plug installed inside the tubular shell, an upper plug, a magnetic induction heating element (4) fixed between the lower plug and the upper plug (3), and an electronic cigarette atomization material carrier (5).

The electronic cigarette atomization material carrier (5) is sleeved outside the magnetic induction heating element (4), and the inner surface of the electronic cigarette atomization material carrier (5) is adjacent to the outside of the magnetic induction heating element (4). The electronic cigarette atomization material is adsorbed in the electronic cigarette atomization material carrier (5). The lower plug through hole (21), the smoke flow channel (41), the upper plug through hole (31), and the mouthpiece section (200) are in communication.

[0004] The inventor found in practical application that the structure of the new cartridge can be further optimized to increase the adsorption amount of the electronic cigarette atomization material, and at the same time, the product structure is simplified to improve the production efficiency, thus the present utility model is proposed.

[0006] In order to achieve the above object, the utility model provides a novel big storage's new type of smoke bullet, the smoke bullet includes tubular shell 1, install in tubular shell 1 inside middle section's middle plug 3, set up in the magnetic induction heating element 4 and electronic cigarette atomization material carrier 5 of middle plug 3 below, tubular shell 1 is made of nonmetal material;Wherein, the bottom of tubular shell 1 is closed and is configured as shell bottom 11, middle plug 3 has the middle through -hole 31 of setting along the length direction and the surrounding through -hole 32 of communicating with middle through -hole 31, the space surrounded by tubular shell 1 and middle plug 3 is electronic cigarette atomization material storage heating integrated area 100, the area of tubular shell 1 inwards, above middle plug 3 is mouthpiece section 200;

[0007] The magnetic induction heating element 4 is at least partially hollow and in the form of a sheet, and at least part of the material of the magnetic induction heating element 4 is metal.

[0008] One side of the magnetic induction heating element 4 abuts at least part of the surface of the electronic cigarette atomization material carrier 5 and is disposed in the electronic cigarette atomization material storage heating integrated area 100, and the electronic cigarette atomization material carrier 5 has electronic cigarette atomization material adsorbed therein; the top end of the electronic cigarette atomization material carrier 5 and the magnetic induction heating element 4 abut the lower surface of the middle plug 3, and the bottom end of the electronic cigarette atomization material carrier 5 and the magnetic induction heating element 4 abut the shell bottom 11; the other side of the magnetic induction heating element 4 and the inner wall of the tubular shell 1 form an air inlet buffer area 2, and the air inlet buffer area 2 communicates with the surrounding through -hole 32.

[0012] In the utility model, the tubular shell 1 has the shape of a hollow tube, and other elements installed therein thus have the shape of a column or a hollow column, so as to facilitate assembling them together. For the convenience of manufacturing, their cross sections can be circular, but other cross sections of polygonal hollow tubes or polygonal hollow columns can also achieve similar functions.

These layered adsorption materials can be used alone or in combination, and they all have certain adsorption properties and air permeability.

[0024] When multiple layered adsorption materials are used, if the material includes high-temperature-resistant natural fiber cotton, the high-temperature-resistant natural fiber cotton is preferably adjacent to the magnetic induction heating element 4 to exert its high-temperature-resistant property and better avoid local carbonization that may occur when the magnetic induction heating element 4 is heated. If the material contains oil-absorbing cotton, the oil-absorbing cotton is preferably arranged on the outermost layer to exert its excellent adsorption properties.
