DETAILED DESCRIPTION OF THE INVENTION

[0014] This invention will be further described in conjunction with the figures and the following embodiments:

[0015] Referring to FIG. 1, FIG. 2 and FIG. 3, an annular stereoscopic-heating electronic cigarette with a replaceable inner container, comprises: a cylindrical electronic cigarette body; wherein the electronic cigarette body comprises smoke-filtering member 1, annual stereoscopic-heating member 2 and heat-controlling member 3; wherein: annual stereoscopic-beating member 2 comprises annual stereoscopic-heating casing 21, and openwork member 22 for conducting heat. Nickel cadmium (Ni-Cd) heating coil 23 is spirally wind around and firmly contacts to the exterior surface of openwork member 22, replaceable shredded tobacco inner container 24 is sleeved within openwork member 22 the exterior of Ni-Cd heating coil 23 and the bottom of openwork member 22 are respectively wrapped around by asbestos heat-insulating layer 25; short-circuit contactor 26 is set: on the bottom of annular stereoscopic-heating casing, 21 and connects to Ni-Cd heating coil 23.

[0016] Openwork member 22 in this invention is an aluminum hollowed cylinder with a plurality of holes set on its circumferential surface. While smoking, heat produced by Ni-Cd heating coil 23 will be passed onto aluminum hollowed cylinder, expanding the heating area from line to plane. At the same time, the produced heat can rapidly flow around through the plurality of holes on the circumferential surface. As a result, a stereoscopic-heating condition is formed and acts on the shredded tobacco inner container, so that the shredded tobacco is heated rapidly and evenly.

[0017] Smoke-filtering member 1 and heat-controlling member 3 are respectively connected to the two ends of annular stereoscopic heating member 2 by threaded connection. Smoke-filtering member 1 comprises cigarette holder 11, wherein: cigarette holder 11 is sleeved on cigarette holder union joint 12, filter piece 13 is set on the bottom of cigarette holder 11, cigarette holder protecting cover 14 is set on the upper part of cigarette holder union joint 12, and the lower part of cigarette holder union joint 12 connects to annular stereoscopic-heating member 2.

[0018] By the threaded connection, smoke-filtering member 1 can firmly connect to heat-controlling member 3, and the connection provides a better sealing. At the same time, it is easy to draw out the shredded tobacco inner container and put the shredded tobacco in, which provides convenience for cleaning the tobacco tar and consequently reduces to production of harmful smoke.

[0019] Heat-controlling member 3 comprises heat-controlling casing 31 and power source 32 within heat-controlling casing 31. Universal Serial Bus (USB) interface 33 is set on the bottom of heat-controlling casing 31, Battery short-circuit contactor 34, which is matching with short-circuit contactor 26, is set on the upper part of heat-controlling casing 31. Printed Circuit Board Assembly (PCBA) controlling board 35 and plurality of controlling buttons 36 corresponding to PCBA controlling board 35 are set on the upper part of power source 32.

[0020] The adoption of USB interface 33 is convenient for charging. By accurately controlling the baking and burning temperature and heating time for the shredded tobacco via PCBA controlling board 35, the shredded tobacco cart get a more complete burning, and double the smoking time than the normal cigarette, and further reduce the production of harmful smoke.

[0021] The shape of smoke-controlling button 36 is a triangle. A plurality of bumps, which can be a protection and are designed according to human engineering, are evenly set on the surface of smoke-controlling button 36. A plurality of recesses, which can be a protection and are designed according to human engineering, are set on the surface of annular stereoscopic-heating casing 21 and heat-controlling casing 31.

[0022] This invention is designed according to human engineering, and the appearance is small and exquisite. It is convenient to be clamped by fingers and also convenient for the user to smoke and carry.

[0023] As described above, any corresponding modification made by one of ordinary skill in the art without creative effort should be considered as falling within the protection scope of this invention.
