Description

[0001] The disclosure relates to a heater.

[0002] Conventionally, a heater comprises a ceramic core comprising one or two through holes, and thus one or two metal wires are disposed in the one or two through holes. The design limits the output power of the heater, and the heater can only produce a small amount of heat and little vapor. EP 3 479 706 A1 and CN 206137192 U each recite an atomizer of an electronic cigarette. The atomizer includes an atomizing seat (5) and an atomizing unit (6). The atomizing unit (6) includes a ceramic atomizing rod (61) made from a ceramic material, a heating wire (62) wound around the ceramic atomizing rod (61), and a lead wire (63) connected to both ends of the heating wire (62). The atomizing seat (5) is a high-temperature resistant tubular body. The ceramic atomizing rod (61) is vertically disposed in the atomizing seat (5). In one embodiment of EP 3 479 706 A1 and CN 206137192 U, the atomizing seat (5) includes three vertical supporting grooves (52), and each vertical supporting groove (52) is installed with one atomizing unit (6). The heating wires (62) of the three atomizing units (6) are parallelly connected to a power source. EP 3 020 292 A1 recites an atomizing device. The device includes: a main body defining an air inlet and an air passage, the air inlet being in communication with the air passage; a mouthpiece arranged at an end of the main body; a liquid chamber in the main body, the liquid chamber being configured for storing a tobacco liquid; at least one heating element arranged in the air passage, the at least one heating element being configured for healing the tobacco liquid to form aerosol; and a permeating component having a heat absorbing surface, the at least one heating clement being in contact with the heat absorbing surface, the permeating component being configured for guiding the tobacco liquid to the heat absorbing surface for atomization. WO 2019 / 014885 A1 recites an atomizer including an atomizing core assembly and an oil storage assembly. The atomizing core assembly is installed in a cavity of the oil storage assembly and includes an atomizing sleeve assembly (12) and a heating assembly (11). The heating assembly (11) is installed in a cavity of the atomizing sleeve assembly (12) and includes a microporous ceramic assembly (111). The microporous ceramic assembly (111) includes a first mounting position (1111) and a second mounting position (1112). The first mounting position (1111) is provided with cotton (112), and the second mounting position (1112) is provided with a heating wire (113). US 2016 / 000146 A1 recites a heating assembly for an e-cigarette. The assembly includes a ceramic e-liquid conduit in cylindrical shape with a ceramic wall around to store e-liquid, and at least one heating wire wound on and around the internal ceramic wall of the ceramic e-liquid conduit.

[0003] The disclosure provides a heater comprising a core and a metal wire secured to the core. The core comprises three through holes.

[0004] In a class of this embodiment, the metal wire comprises a first part coiled into a spiral disposed in one of the three through holes, and a second part extending out of the core to form a pin.

[0005] In a class of this embodiment, the heater comprises three metal wires; the three metal wires each are coiled into the spiral and are disposed in the three through holes, respectively; each metal wire comprises two pins; and the three metal wires are parallel-connected to each other.

[0006] In a class of this embodiment, the three through holes are cylindrical, and the three metal wires each are coiled into a cylindrical spiral.

[0007] According to the invention, the core is cylindrical. FIG. 1 is a schematic diagram of a heater in accordance with one embodiment of the disclosure; FIG. 2 is another schematic diagram of a heater in accordance with one embodiment of the disclosure; and FIG. 3 is a sectional view of a heater in accordance with one embodiment of the disclosure.

[0008] 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.

[0009] As shown in FIGS. 1-3, the disclosure provides a heater comprising a core 1 and a metal wire 2 secured to the core. The core comprises three through holes 3. When current is flowing through the metal wire, the metal wire is heated. According to the invention, 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 core to heat the e-liquid to produce vapour.

[0010] According to the invention, the core is quartz, mica, or jade. The three though holes of the core are square, oval, or a combination thereof. The metal wires in the through holes includes but is not limited to a cylindrical spiral.

[0011] The following advantages are associated with the heater of the disclosure:

[0012] 1. The 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 vapour. The heater is compatible with a variety of e-liquid, with fast temperature rise, and no e-liquid splashes in the heating process.

[0013] 2. The 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.
