Atomizer with two heating wires

Description

[0001] The disclosure relates to an atomizer comprising two heating wires.

[0002] Conventionally, the atomizer of the electronic cigarettes is spiral structure with a single cylindrical hole. Thus, the heating area of the atomizer is small and thus the electronic cigarettes can only produce a small amount of vapor. US 2018 / 146716 A1 discloses an electronic cigarette. The electronic cigarette includes a heating wire, a connecting holder, an atomizing cap, and an atomizing holder. The connecting holder is connected to one end of the atomizing cap, the atomizing holder is inserted into the other end of the atomizing cap, and the heating wire is arranged in the atomizing holder. The connecting holder includes an air inlet slot. A predetermined spacing is arranged between the atomizing holder and the atomizing cap. Side walls of the atomizing holder and the atomizing cap both have a through hole for tobacco oil to flow into and contact the heating wire. WO 2019 / 051880 A1 recites an atomizer of an electronic cigarette. The atomizer includes a hollow outer casing, an oil guiding cotton, and a heating element comprising a plurality of heating wires connected in parallel. A bracket is disposed in the outer casing. The oil guiding cotton is disposed in an inner surface of the bracket, and the heating wires are disposed in an inner side of the oil guiding cotton. CN 204837998 U, CN 106418712 A, and CN 102356929 A each recite a device including two heating wires connected in parallel.

[0003] The disclosure provides an atomizer, comprising a ceramic core, a first heating wire, and a second heating wire; the ceramic core comprises a body comprising a through hole; the first heating wire is soldered on the second heating wire.

[0004] In a class of this embodiment, the first heating wire and the second heating wire are coiled side by side in the through hole to form a helical structure.

[0005] In a class of this embodiment, the first heating wire is soldered on the second heating wire in parallel; and one end of each of the first heating wire is soldered on the second heating wire and is connected to a pin.

[0006] In a class of this embodiment, the through hole is cylindrical, and a coiled part of each of the first heating wire and the second heating wire is cylindrical and inlaid in an inner wall of the ceramic body surrounding the through hole.

[0007] According to the invention, the body of the ceramic core is cylindrical.

[0008] In a class of this embodiment, the first or second heating wire comprises one or more curved meshed structures, planar helical structures, spiral structures, or a combination thereof connected in series or in parallel.

[0009] Not according to the invention, the body of the ceramic core is in the shape of ellipsoid, flat ellipse, hemisphere, cone, bowl, triangle, quadrilateral, polygon; and the ceramic core is an equivalent of quartz, crystal, mica, agate, jade. FIG. 1 is an exploded view of an atomizer in accordance with one embodiment of the disclosure; FIG. 2 is a schematic diagram of an atomizer in accordance with one embodiment of the disclosure; and FIG. 3 is a sectional view of an atomizer in accordance with one embodiment of the disclosure.

[0010] To further illustrate, embodiments detailing an atomizer are described below. It should be noted that the following embodiments are intended to describe and not to limit the disclosure.

[0011] As shown in FIGS. 1-3, the disclosure provides an atomizer comprising a ceramic core 1, a first heating wire 3, a second heating wire 4, and a pin 5. The ceramic core 1 comprises a body comprising a through hole 2. The first heating wire 3 and the second heating wire 4 are coiled side by side in the through hole 2 to form a helical structure. In certain embodiment, the first heating wire 3 and the second heating wire 4 are embedded in the ceramic core, are exposed in the through hole 2, or are secured to the inner wall of the ceramic body surrounding the through hole. Optionally, the first heating wire 3 and the second heating wire 4 are disposed side by side. Two pins 5 are soldered on the first heating wire 3 and the second heating wire 4 respectively for electric conduction and produce heat. The heat is transferred to the ceramic core 1 to atomize the e-liquid.

[0012] Not according to the invention, the ceramic core is in the shape of ellipsoid, flat ellipse, hemisphere, cone, bowl, triangle, quadrilateral, polygon; and the ceramic core is an equivalent of quartz, crystal, mica, agate, jade. The first or second heating wire comprises one or more curved meshed structures, planar helical structures, spiral structures, or a combination thereof connected in series or in parallel. The body comprising one or more through holes in the shape of circle, ellipse, square, triangle and polygon.

[0013] The following advantages are associated with the atomizer of the disclosure: 1. The ceramic core comprises the first heating wire and the second heating wire coiled side by side in the through hole to form a helical structure, which enlarges the heating area, increases the heat value, accelerates temperature rise and increases the vapor amount. 2. The atomizer may comprise two pins soldered on the first heating wire and the second heating wire respectively for electric conduction and produce heat. 3. The two metal heating wires may be a helical structure and are soldered together in parallel.
