The disclosure relates to an electronic cigarette.
Conventional electronic cigarettes include a heating wire to heat and atomize the tobacco material. In general, the heating wire is directly immersed into the tobacco material. The direct contact of the heating wire and the tobacco material may degrade the quality of the tobacco material.
The disclosure provides an electronic cigarette, comprising a microwave heating module and an aerosol generator; the microwave heating module comprises a cup, a cylindrical shielding net, a magnetron, and a microwave source; the cup is fixed in the cylindrical shielding net for accommodating a tobacco material; the cylindrical shielding net is disposed above the microwave source; the magnetron is disposed on the microwave source; in a power-on state, the magnetron emits microwave; the microwave is released via the microwave source into the cylindrical shielding net to heat and atomize the tobacco material in the cup; and the microwave heating module is disposed in the aerosol generator.
In a class of this embodiment, the microwave heating module further comprises a cover; the cover is disposed on the cylindrical shielding net so as to hold the microwave emitted by the microwave source in the cylindrical shielding net, thereby concentrating the microwave energy on the tobacco material and improving the heating efficiency.
In a class of this embodiment, the microwave heating module comprises a control panel and a battery; the battery is soldered on an input end of the control panel; an output end of the control panel is soldered to an input end of the microwave source for inputting alternating current to the microwave source so that the magnetron emits the microwave.
In a class of this embodiment, the microwave heating module further comprises a silicone sleeve; the silicone sleeve is disposed around the microwave source; and the magnetron on the microwave source is exposed out of the silicone sleeve.
In a class of this embodiment, the cup comprises a non-metallic material including but not limited to glass, ceramics, quartz, crystal, agate, and jade, and a metal material, and the cup is in the shape of a cylinder, oval, or convex pot.
In a class of this embodiment, the aerosol generator comprises a sleeve, and the microwave heating module is fixed in the sleeve.
In a class of this embodiment, the aerosol generator comprises a housing and a button; the sleeve comprises an upper part exposed out of the housing and a lower part disposed in the housing; the button is disposed on the control panel and exposed out of a side wall of the housing; and the button is configured to switch on a power source.
In a class of this embodiment, the electronic cigarette further comprises a mouthpiece; the mouthpiece is disposed on the sleeve; the sleeve comprises at least one air vent; when in use, air enters the cylindrical shielding net via the at least one air vent of the sleeve and drives vapor resulting from the atomization of the tobacco material in the cup by the microwave to flow from the cover to the mouthpiece for user's inhaling.
To further illustrate, embodiments detailing an electronic cigarette are described below. It should be noted that the following embodiments are intended to describe and not to limit the disclosure.
Principle of microwave heating: microwave heating is a multiphysics phenomenon that involves electromagnetic waves and heat transfer; any material that is exposed to electromagnetic radiation will be heated up owing to the collision between the material molecules. The rapidly varying electric and magnetic fields lead to sources of heating.
As shown in
In certain embodiments, the battery 13 comprises 1-4 18650-type lithium cells, and each cell is 2200 mA·h. The output power range of the microwave source is 2.0-260 W, the voltage range is AC: 3.7-14.8V, the temperature range is 100-350° C., and the microwave frequency is 2400-2500 Mhz.
The following advantages are associated with the electronic cigarette of the disclosure:
It will be obvious to those skilled in the art that changes and modifications may be made, and therefore, the aim in the appended claims is to cover all such changes and modifications.
