Description
Technical Field
The utility model belongs to the electrical heating smoking set field, in particular to spiral heating element.
Background
The heating element of the existing electric heating smoking set is generally a sheet-shaped or rod-shaped heating element, a heating material is wound or printed on the heating element, and the heating material generates heat after being electrified. However, the following problems are present:
(1) uneven heating: the heating elements in the shape of sheets or rods are all in a central heating mode, so that the phenomena of nonuniform heating of tobacco sections and easy burning of the center of a cigarette easily occur, and the smoking feeling of consumers is reduced.
(2) The cigarette easily falls out during smoking: the roughness of the outer surface of the heating element in the form of a sheet or rod is not great, so that the cigarette is not firm after insertion and is easily carried out by the lips of the consumer during smoking. Therefore, the consumer needs to take care to prevent the cigarettes from being carried over each puff, which can affect the smoking experience.
In addition, the sheet heating element has the problem of poor rigidity and easy breakage, which brings certain inconvenience to later products in use.
Disclosure of Invention
In order to solve the above problems, the present invention is provided.
The utility model provides a spiral heating element in a first aspect, which is characterized in that the spiral heating element comprises a spiral body 1 and a heating material track 2;
wherein the spiral body 1 is a cone or a truncated cone 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 part 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 a tooth 5 and a groove 6, and the heat generating material track 2 is provided at least one of the tooth 5 and the groove 6.
The other end of the conductive material layer 3 is used for connecting an external power supply circuit. Wherein, the root of the spiral body 1 is the end with larger cross section diameter of a cone-shaped body or a truncated cone-shaped body.
Preferably, the surface of the spiral body 1 is provided with an insulating layer. In order to prevent the short circuit phenomenon of the heat-generating material layer 2 during operation.
Preferably, the number of turns of the thread 4 is 2-3.
Preferably, the material of the spiral body 1 is selected from one of metal, ceramic and heat-resistant plastic. Wherein heat resistant means resistant to temperatures of at least 400 degrees celsius without decomposition.
Preferably, the heat-generating material track 2 is an electric heat-generating material layer printed on the surface of the tooth 5 and/or the groove 6.
Preferably, the heating material track 2 is an electric heating wire, and the electric heating wire is embedded in the groove 6.
The utility model discloses the second aspect provides the first aspect heating element be arranged in the electrical heating smoking set improve the heating homogeneity and improve the usage that the frictional resistance between a cigarette and the heating element.
The utility model discloses following beneficial effect has:
(1) the utility model discloses a spiral heating element, inside be solid conical body or truncated cone shape body, compare in slice heating element, have better intensity, be difficult to damage.
(2) The utility model discloses a spiral heating element, the heating material layer sets up in the tooth of spirochaeta screw thread or recess, all have even arranging in the direction of perpendicular and parallel cigarette longitudinal axis, have better heat equilibrium. Therefore, the cigarette is heated more uniformly, the heat conduction efficiency is high, the problem of serious central part carbonization caused by non-uniformity of heating of the sheet-shaped and bar-shaped heating elements can be well solved, and the smoking taste is improved.
(3) The outer surface of the spiral heating element is provided with threads, which is rougher and firmer when being inserted into a cigarette, and the cigarette is not easy to be taken out during suction, thereby solving the problem that the cigarette is easy to fall off when the smoking set using the sheet and rod-shaped heating elements is used for suction.

Detailed Description
The present invention will be further described with reference to the following detailed description.
Example 1
The spiral heating element of the present invention, as shown in fig. 1, comprises a spiral body 1, a heating material track 2 in the form of an electric heating wire, and a conductive material layer 3 in the form of a conductive foil; wherein, spirochaeta 1 is the ceramic truncated cone shape body that the surface has 3 rings of screw threads 4, and its surface spraying has insulating coating, screw thread 4 has tooth 5 and recess 6, the electric heater winding is in recess 6, the diameter of electric heater can be more than, equal to or be less than the degree of depth of recess to the tobacco of abundant contact cigarette makes its abundant heating after, toasts a cigarette more even. The conductive foil is printed on the surface of the root of the spiral body 1, one end of the conductive foil is connected with the electric heating wire, and the other end of the conductive foil is connected with an external power supply circuit. After the external circuit supplies power, current flows through the electric heating wire through the conductive foil, and the electric heating wire utilizes the current heat effect to bake cigarettes after being electrified.
