Background technique

In a conventional electronic cigarette construction, the electronic cigarette includes an oil storage assembly for storing the smoke oil and an atomizer for atomizing the smoke oil, wherein the atomizer further includes an oil storage cotton and is used for the smoke in the oil storage cotton. The oil heats the atomized electric heating element. When the electronic cigarette is operated, the smoke oil is sucked from the oil storage assembly into the oil storage cotton of the atomizer, and the electric heating element is heated by the battery component to atomize the smoke oil in the oil storage cotton into smoke for the smoker to absorb. However, in the current design, the electric heating element is easy to make the smoke oil atomization insufficient and easy to burn cotton during the heating and atomizing process of the oil storage cotton.

Summary of the invention

Based on this, it is necessary to provide an oil aerosolization method that is sufficient for the problem that the oil mist is not sufficiently atomized and easily burned during the heating and atomization process of the oil storage cotton in the existing electronic cigarette atomizer. The atomizing core and atomizer that will burn the cotton.

An atomizing core comprising a housing assembly having an atomizing chamber, an atomizing assembly received in the atomizing chamber, the atomizing assembly comprising at least one oil storage member and at least one heat generating portion; wherein the oil storage member includes at least An oil absorbing surface as an outer surface thereof is attached to at least a portion of an outer surface of the oil reservoir that is different from the oil absorbing surface.

An atomizer comprising a main body and a nozzle portion connected to one end of the main body; the main body includes an oil storage assembly having an oil storage chamber and the above-mentioned atomizing core received in the oil storage chamber, the main body also having smoke a passage, one end of the smoke passage is in communication with the nozzle portion, and the other end is in communication with the atomization chamber.

The atomizing core and the atomizer are configured to absorb the oil by using an outer surface of the oil storage body as an oil absorbing surface, so that at least part of the outer surface of the oil body different from the different surface of the oil absorbing surface is attached to the heat generating portion. The outer surface of the heat-generating part and the oil-storing body are different from the oil-absorbing surface, which can ensure that the heat-generating part does not affect the function of sucking the oil-absorbing surface on the oil-absorbing surface. On the other hand, the heat-generating part and the oil-storing body have a larger bonding surface and can be in a larger area. The internal contact with the oil storage body enables the oil to be aerosolized sufficiently and does not easily burn the oil storage member.

This arrangement enables the oil suction face 23 of the oil reservoir 21 to receive the tobacco oil entering from the oil inlet port 14 to a greater extent, and to ensure that the amount of smoke oil stored in the oil storage member 21 is sufficient.

As shown in FIG. 2, in the present embodiment, the atomizing assembly 20 includes an oil reservoir 21 and two heat generating portions 22. The heat generating portion 22 has a plate shape, and the oil storage member 21 has a block shape, and the two heat generating portions 22 are completely attached to the opposite outer surfaces of the oil reservoir 21 opposite to the oil absorbing surface 23, respectively. The heat generating portion 22 extends along the atomizing chamber 11 and its width can be adapted to the inner size of the atomizing chamber 11 to the maximum extent, for example, the width thereof can be the radial dimension of the atomizing chamber at the maximum. In other embodiments, the heat generating portion 22 may also be attached to only a portion of the surface of one side surface of the oil storage member 21, which is not limited herein. When the heat generating portion 22 is energized, the oil stored in the oil storage member 21 can be quickly heated and atomized into the atomizing chamber 11, and the atomizing chamber communicates with the suction nozzle for the smoker to suck.
