Description

A spiral heating element

technical field

The utility model belongs to the field of electric heating smoking sets, in particular to a spiral heating element.

Background technique

The heating element of the existing electric heating smoking device is generally a sheet-shaped or rod-shaped heating element, on which a heating material is wound or printed, and the heating material generates heat after being energized. But there are the following problems:

(1) Uneven heating: The heating elements in the form of sheets or rods are centrally heated, which is prone to uneven heating of the tobacco section and the phenomenon that the center of the cigarette is easily baked, which reduces the smoking experience of consumers.

(2) The cigarettes are easy to fall out during smoking: the outer surface of the sheet-shaped or rod-shaped heating element is not rough, and the cigarettes are not very firm after being inserted, and are easily taken out by the lips of consumers during smoking. Therefore, consumers need to be careful to prevent the cigarette from being taken out every time they take a puff, which will affect the smoking experience.

In addition, the sheet heating element also has the problem of poor rigidity and easy to break, which brings certain inconvenience to the later use of the product.

SUMMARY OF THE INVENTION

In order to solve the above problems, the present invention is proposed.

Wherein, the spiral body 1 is a conical body or a truncated cone body with a thread 4 on the surface, and the heating material track 2 is arranged on the surface of the spiral body 1;

The heating element further comprises a conductive material layer 3, the conductive material layer 3 is arranged on the surface of the root of the spiral body 1, and one end of the conductive material layer 3 is in contact with the heating material track 2;

The thread 4 has teeth 5 and grooves 6, and the heat-generating material track 2 is provided at at least one of the teeth 5 and the grooves 6.

The other end of the conductive material layer 3 is used to connect to an external power supply circuit. Wherein, the root of the helical body 1 is the end with the larger diameter of the cross-sectional diameter of the cone or truncated cone.

Preferably, the surface of the spiral body 1 is provided with an insulating layer. In order to prevent the short circuit phenomenon of the heating material layer 2 during operation.

Preferably, the number of turns of the thread 4 is 2-3 turns.

Preferably, the material of the spiral body 1 is selected from one of metals, ceramics, and heat-resistant plastics. Among them, heat resistance means that it can withstand a temperature of at least 400 degrees Celsius without decomposition.

Preferably, the heating material track 2 is an electric heating material layer, which is printed on the surface of the teeth 5 and/or the grooves 6 .

Preferably, the heating material track 2 is an electric heating wire, which is embedded in the groove 6 .

A second aspect of the present invention provides the use of the heating element described in the first aspect for improving the heating uniformity and the frictional resistance between the cigarette and the heating element in an electrically heated smoking set.

The utility model has the following beneficial effects:

(1) The spiral heating element of the present invention has a solid cone or truncated cone inside, which has better strength and is not easy to be damaged compared with the sheet heating element.

(2) In the helical heating element of the present invention, the heating material layer is arranged in the teeth or/and grooves of the helical thread, and is evenly arranged in the directions perpendicular to and parallel to the longitudinal axis of the cigarette, with better caloric balance. Therefore, the heating of the cigarettes is more uniform, and the heat conduction efficiency is high, which can well solve the serious problem of carbonization in the central part caused by the heating unevenness of the sheet-shaped and rod-shaped heating elements, and improve the smoking taste.

(3) The outer surface of the helical heating element has threads, which are rougher and more firmly inserted into the cigarette. The cigarette is not easy to be taken out during smoking, which solves the problem that the smoking device using the sheet-shaped and rod-shaped heating element is easy to fall off during smoking. The problem of cigarettes.
