DE202014008826U1 - Evaporator with heating wire made of titanium - Google Patents

Abstract

Main claim An evaporator comprising at least one atomization cavity [33], an evaporator wall [30], a liquid tank [31], an evaporator body [34], fiber material [35] characterized by a heating wire [32] made of titanium.

Description

The invention relates to an evaporator for use in electronic cigarettes with a heating wire made of titanium according to the preamble of the main claim.

Electronic cigarettes have established themselves as a niche product in the market. With the electronic cigarette, nicotine-containing or nicotine-free liquids (liquid) are vaporized and absorbed by the consumer via inhalation via the lungs.

The process of evaporation takes place in an evaporator in which the liquid is heated by means of a heating wire, through which electrical currents are conducted.

State of the art

Out US 1775947 (Electric vaporizer, Robinson, J .; 1930/09/16), US 3200819 A (Smokeless non-tobacco cigarette, A, G.H., 1965) as well as from US 8393331 (Electronic atomization cigarette, Hon, L .; 2013) is the construction of a conventional evaporator for use in electronic cigarettes known. A simplified illustration of the evaporator is in seen.

An evaporator wall [ 30 ] is surrounded by a liquid tank [ 31 ] and an evaporator body [ 34 ]. The evaporator body may consist of aluminum, nickel, metal fiber fleece, polymer (macromolecule) or ceramic materials.

A heating wire [ 32 ], which according to the current state of the art consists of platinum, nickel-chromium alloy, iron-chromium-aluminum alloy with rare earths or also in the form of a plate made of a conductive ceramic or PTC ceramic, is located within an atomization cavity [ 33 ].

A liquid in the liquid tank is filled with fiber material [ 35 ], which may consist of artificial or natural fibers, transported to the heating wire. With the start of the evaporation process, a circuit is closed with the heating wire and the heating wire heats the liquid.

Defects of the known designs

In the wires used so far, an undesirable taste, depending on the heating wire material used, occur in the steam.

By heating by means of a heating wire made of the materials used according to the prior art, in addition to the liquid, also unwanted potentially harmful particles are evaporated.

The specific resistance of the material used for the heating wire of an evaporator according to the prior art is relatively high. The higher the resistivity, the more voltage is needed to achieve the heating power necessary to vaporize the liquid.

Problem solving the invention

An evaporator described and claimed in this application is used for the heating wire [ 32 ] the material titanium instead of the previously used materials. The titanium wire can be used in different degrees of purity.

Achieved benefits

The use of titanium wire eliminates the deficiencies described in the "Deficiencies of the Previous Embodiments" section, or at least achieves an optimized balance between the delivery of harmful particles and resistance of the heating wire.

The specific resistance of titanium wire is small compared to many wire materials used so far. A low resistance of the heating wire offers advantages in the evaporation of liquids due to a good performance at the same voltage.

The vaporization process with a titanium heating wire releases less harmful particles than heating wires made from prior art materials.

When vaporizing liquids by means of a heating wire made of titanium, is not attributable to the heating wire Nebengeschmack not or at least hardly taste.

embodiment

The exemplary construction of an evaporator is in seen.

The in a liquid tank [ 31 ] is liquid by means of a fiber material [ 35 ] to a heating wire [ 32 ], which consists of titanium and enters a nebulization cavity [ 33 ], sucked. The heating wire is heated by means of electrical currents and the liquid aspirated by the fiber material is evaporated in the sputtering cavity.
