BRIEF DESCRIPTION OF THE DRAWINGS

[0009] FIG. 1 is a schematic diagram of a heater in accordance with one embodiment of the disclosure;

[0010] FIG. 2 is another schematic diagram of a heater in accordance with one embodiment of the disclosure; and

[0011] FIG. 3 is a sectional view of a heater in accordance with one embodiment of the disclosure.

DETAILED DESCRIPTION

[0012] To further illustrate, embodiments detailing a heater are described below. It should be noted that the following embodiments are intended to describe and not to limit the disclosure.

[0013] As shown in FIGS. 1-3, the disclosure provides a heater comprising a ceramic core 1 and a metal wire 2 secured to the ceramic core. The ceramic core comprises three through holes 3. When current is flowing through the metal wire, the metal wire is heated. In certain embodiments, the heater comprises three metal wires. The three metal wires each comprise a first part coiled into a spiral disposed in one of the three through holes, and a second part extending out of the ceramic core 1 to act as a pin. In certain embodiments, each metal wire comprises two pins. The positive terminals of the pins of the three metal wires are connected to each other, and the negative terminals thereof are connected to each other, to form a parallel structure. When current is flowing through the three metal wires, the three metal wires are heated. The heat is transferred to the ceramic core to heat the e-liquid to produce vapor.

[0014] In certain embodiments, the ceramic core is replaced by quartz, crystal, mica, jade or other materials. The ceramic core is a cuboid. cube, or polygon. The three though holes of the ceramic core are square, oval, or a combination thereof. The metal wires in the through holes includes but is not limited to a cylindrical spiral.

[0015] The following advantages are associated with the heater of the disclosure:

[0016] 1. The ceramic core is a cylinder comprising three through holes, which is convenient to manufacture. The three metal wires are connected in parallel, so that the heater has a long service life, high output power and can produce much vapor. The heater is compatible with a variety of e-liquid, with fast temperature rise, and no e-liquid splashes in the heating process.

[0017] 2. The ceramic core comprises three through holes. The three through holes is not easily completely blocked by the precipitate of the e-liquid even for a long time of use, thus extending the service life of the heater.

[0018] 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.
