Detailed ways

The utility model will be further described in detail below in conjunction with the accompanying drawings and specific embodiments to facilitate a clear understanding of the utility model, but they do not limit the utility model.

As shown in Figures 1 to 4, it is a structural diagram of an electric smoking system heater without heat preservation function, including a shell 4, and a high-temperature insulating tube 9 is sleeved inside the shell 4, and a high-temperature insulating tube 9 is sleeved inside the high-temperature insulating tube 9. There is a heating sheet 1, the heating sheet 1 is a cylindrical structure wound by a metal sheet, a heating cavity 3 is arranged inside the heating sheet 1, fixed antennae 2 are arranged at both ends of the heating sheet 1, and the heating sheet 1 Electrode tentacles 5 are arranged on the sheet 1, and the electrode tentacles 5 are connected with a power supply.

As shown in Figure 5-9, it is the electric smoking system heater with heat preservation function of the present invention. Compared with the electric smoking system heater in Figure 1-Figure 4, the difference is that the utility model heating sheet includes two parts 1a and 1b , where part 1a is connected in parallel with temperature switch 6 and then connected in series with another part 1b and circuit switch 7. An insulating barrier layer 8 is provided between the two parts 1a and 1b of the heating chip.

As shown in Figure 7, the first scheme of the utility model heating sheet structure: the heating sheet 1 is formed of several sections wound by metal sheets, and a gap is provided between the two adjacent sections of metal sheets 1.1, 1.2, The part of the connection section 1.3 between the two adjacent metal sheets 1.1 and 1.2 protruding from both ends of each section of the metal sheet is the fixed antenna 2.

As shown in Figure 8, the second scheme of the heating plate structure of the utility model: the heating plate 1 is wound by metal sheets to form several sections, and a gap is provided between the two adjacent sections of metal sheets 1.1, 1.2, A fixed antenna 2 is provided on the connection section 1.3 between the two adjacent sections of metal sheets 1.1, 1.2.

As shown in Figure 9, the third scheme of the heating plate structure of the utility model: the heating plate 1 is formed of several sections by winding metal sheets, and a gap is provided between the two adjacent sections of metal sheets 1.1, 1.2, Between the two adjacent metal sheets 1.1, 1.2 is a connection section 1.3.

Wherein, in the heater structure constituted by the heating chip 1 , the heating chip 1 is connected to the external power supply electrode through the heating chip electrode contact pin 5 .

In the specific practical process of the electric heater, the utility model inserts cigarettes into the heating chamber 3, turns on the loop power supply, and the heating sheet 1 directly heats the cigarettes, and the heating sheet 1a and the temperature control switch 6 form a parallel circuit , before the temperature control switch 6 reaches the preset temperature, the heating sheet 1a is in a non-working state, and only the heating sheet 1b is working. When the heater reaches the atomization temperature of tobacco products, in order to prevent the cigarette from overheating and burning, the temperature control switch 6 is turned off Turn on, the heating sheet 1a and the heating sheet 1b form a series circuit to heat the cigarette together, the resistance value of the series resistance becomes larger, and the power for heating the tobacco product becomes smaller. In the experiment, after adjusting the power of the heater to achieve a basic balance between the heating heat and the heat loss, the temperature of the heater can be kept constant, and the uninterrupted and continuous atomization of cigarettes can be realized.

In the utility model, the heating sheet 1 is formed in a certain arc by the elasticity of the metal sheet in the high-temperature insulating tube 9, which can be in closer contact with the tobacco.
