Detailed Description
The technical solutions in the embodiments of the present invention will be described clearly and completely with reference to the accompanying drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only some embodiments of the present invention, not all embodiments. Based on the embodiments in the present invention, all other embodiments obtained by a person skilled in the art without creative work belong to the protection scope of the present invention.
Referring to fig. 1 to 4, an electronic cigarette heating assembly is mounted on a smoking set body a and used for heating tobacco, a control unit is arranged in the smoking set body a, and the electronic cigarette heating assembly comprises a shell 1 and an electric heating assembly 2; the shell 1 is made of steel, one end of the shell 1 is arranged on the smoking set body a, a cavity is arranged in the shell, and the electric heating component 2 is sleeved in the cavity;
the electric heating component 2 comprises a heating wire 20, an insulating bracket 21 and a pin electrode 22; the heating wire 20 is a pure platinum wire, and the heating wire 20 is wound on the insulating bracket 21; two pin electrodes 22 are arranged and are both fixedly connected to the insulating support 21, the two pin electrodes 22 are respectively electrically connected with the wire ends at two ends of the heating wire 20, and one end of each pin electrode 22 extends out of the cavity and is electrically connected with the control unit. In this embodiment, two pin electrodes 22 are welded to the insulating support 21.
The shell 1 made of steel is not easy to break and has good heat-conducting property because the steel has high strength and better toughness than a ceramic material. In this embodiment, the housing 1 is formed by welding two identical stainless steels in opposite directions.
It should be noted that, the utility model discloses in, still be equipped with the battery in the smoking set body a, the control unit and battery electric connection to the control unit output voltage is invariable relatively. It is known that the smaller the resistance is, the larger the heat generated by the resistance is, and the following formula can be used for calculation:
wherein Q is heating value, P is heating power, U is voltage, R is resistance value, and t is electrifying time;
the resistance value of most materials can change along with the change of temperature, in the utility model discloses in, heating wire 20 uses resistance temperature coefficient to approach the electrically conductive material of linear growth, platinum group metal such as pure platinum silk, palladium, and in this embodiment, heating wire 20 is the pure platinum silk of preferred. The resistance temperature coefficient approaches to linear increase, that is, as the time increases, the temperature increases, and further the resistance value linearly increases, so that when the temperature of the heating wire 20 increases, the resistance value becomes larger, the power thereof decreases, the temperature increasing speed continuously decreases, and the temperature can be controlled more easily by the control unit; the existing nickel heating wire can generate oxidation phenomenon after the temperature is higher than 300 ℃, and the pure platinum wire starts to generate oxidation phenomenon after the temperature is higher than 600 ℃, so that the pure platinum wire heating wire is more stable than the nickel heating wire.
The heating wire 20 can be longitudinally spirally wound on the insulating support 21, and also can be transversely spirally wound on the insulating support 21, because the shell 1 is in a slender structure, in the embodiment, the heating wire 20 is preferably transversely spirally wound on the insulating support 21, so that the distribution of the heating wire 20 is more concentrated, and further the heating effect of tobacco is better.
Specifically, the switch of the smoking set body a is turned on to energize the heating wire 20, and the heating wire 20 generates heat after being energized due to its own resistance. Along with the increase of time, the temperature of the heating wire 20 can rise, so that the resistance of the heating wire is increased, the power is reduced along with the increase of the resistance, the temperature rising speed is reduced continuously, the resistance value of the heating wire is monitored continuously by the control unit, and after the temperature value preset by the control unit is reached, the control unit controls the output power to automatically control the temperature and keep the temperature. The temperature of the heating wire 20 is transmitted to the steel casing 1, and then the casing 1 which is directly contacted with the tobacco is used for baking the tobacco.
Further, the insulating support 21 is a mica sheet, and the mica is a high-temperature-resistant insulating material, so that the insulating support 21 can be prevented from melting after the heating wire 20 is heated.
Further, the lead electrode 22 is made of a material having a low temperature coefficient of resistance, i.e., the resistance thereof changes to a small extent with temperature change, and does not affect the resistance change of the heating wire 20. In this embodiment, the lead electrode 22 is made of copper-nickel alloy.
Further, the shell 1 is provided with an insulating coating on the inner side of the cavity, so that the heating wire 20 in the cavity is prevented from contacting the steel shell 1, and the shell 1 and the heating wire 20 are contacted to cause a short circuit phenomenon.
Further, since the electric heating element 2 generates a high temperature after being energized, the casing 1 is easily oxidized due to the high temperature, and carbonized tobacco is easily left on the casing 1 after the casing 1 is used for many times. Therefore, the outer layer of the shell 1 is provided with the coating with strong oxidation resistance, and the oxidation degree is delayed.
Further, high-temperature resistant ceramic glue is filled between the shell 1 and the electric heating component 2 to fix the heating wire 20 and the shell 1.
Furthermore, one end of the shell 1, which is far away from the smoking set body a, is in a taper shape, so that the shell 1 can be conveniently inserted into tobacco.
