Abstract

An atomizer with a compact structure and convenient assembly is provided. The atomizer includes an atomizing sleeve and an atomizing assembly fixed therein, a liquid reserving space configured for storing a tobacco liquid is defined in the atomizing sleeve. The atomizing assembly includes a fixing sleeve and a porous body arranged therein, an aerosol passage and at least one liquid opening are formed in the fixing sleeve. The porous body absorbs tobacco liquid through the at least one liquid opening, and the porous body is hollow inside and having an atomizing space defined therein. A heating coil configured for heating tobacco liquid absorbed from the porous body into tobacco aerosol is fixed in the atomizing space. The aerosol passage configured for ejecting the tobacco aerosol is in communication with the atomizing space. An electronic cigarette having the atomizer is also provided.

First claim

What is claimed is:

1. An atomizer of an electronic cigarette, comprising:
an atomizing sleeve defining a liquid reserving space therein; and
an atomizing assembly fixed in the atomizing sleeve;
the atomizing assembly comprising a fixing sleeve and a porous body arranged in the fixing sleeve, the fixing sleeve having an aerosol passage defined therein and at least one liquid opening, the porous body absorbing a tobacco liquid through the at least one liquid opening, the porous body being hollow inside and having an atomizing space defined therein, the atomizing space having a heating coil fixed therein, and the heating coil configured for heating the tobacco liquid absorbed from the porous body into tobacco aerosol, the aerosol passage in communication with the atomizing space and configured for ejecting the tobacco aerosol;
wherein the fixing sleeve comprises an upper part, a middle part, and a lower part, the upper part, middle part and the lower part are interconnected, the at least one liquid opening are formed on the middle part, and the porous body is arranged in the middle part;
wherein a top liquid stopper and a bottom liquid stopper are respectively fixed on each of two ends of the porous body and abut with the upper part and the lower part of the fixing sleeve respectively, two through holes are respectively formed in a center of the top liquid stopper and in a center of the bottom liquid stopper and in communication with the aerosol passage and the atomizing space.

2. The atomizer of claim 1 , wherein the atomizing sleeve is made of a transparent material, the upper part and the lower part of the fixing sleeve are respectively extend to be substantially level to two ends of the atomizing sleeve, the upper part, the middle part, and the lower part are cylindrical respectively, and outer diameters of the upper part, the middle part, and the lower part increase in sequence.

3. The atomizer of claim 1 , wherein the porous body is arranged in the middle part along an axial direction of the middle part, the atomizing space is cone-shaped, and an inner diameter of the atomizing space is decreased in sequence from the bottom to the top of the middle part.

4. The atomizer of claim 1 , wherein two protruding flanges configured for fixing the top liquid stopper and the lower liquid stopper are respectively fixed on the upper part and the lower part of the fixing sleeve.

5. The atomizer of claim 1 , wherein the porous body is made of ceramic and has a cylindrical surface facing towards the at least one liquid opening to absorb tobacco liquid.

6. The atomizer of claim 1 , wherein a liquid reserving member wraps around at least partially the middle part of the fixing sleeve, the porous body contacts with the liquid reserving member through the at least one liquid opening.

7. The atomizer of claim 1 , wherein a liquid reserving member wraps around at least partially the porous body, the liquid reserving member is arranged in the middle part of the fixing sleeve and faces towards the liquid opening.

8. An electronic cigarette comprising a battery assembly and an atomizer of claim 1 , the battery assembly configured to be electrically connected to the atomizer.
