Embodiment 1

[0051] The present application discloses an electronic cigarette based on electromagnetic temperature control technology.

[0052] refer to figure 1 , figure 2 , the electronic cigarette based on electromagnetic temperature control technology includes a cigarette rod 1, which is cylindrical in shape, and a power supply device 2 and an atomizer 3 are installed in it. The atomizer 3 includes an induction coil 31 and a metal heating tube 32 passing through the induction coil 31 . The power supply device 2 is used to output a changing current to the induction coil 31, so that the induction coil 31 generates a magnetic field with a changing magnetic flux, so that an eddy current is generated on the metal heating tube 32, so that the metal heating tube 32 generates heat, and the inside of the metal heating tube 32 Cigarettes are stuffed in advance to heat the cigarettes so that the temperature of the cigarettes is kept below 350°C, thereby reducing some harmful substances. The u...

Embodiment 2

[0076] refer to Figure 5 The difference between this embodiment and Embodiment 1 is that a storage cavity for the battery 24 is provided on the side of the metal heating tube 32 in the cigarette rod 1, and the circuit board 42 is located in the storage cavity, and the circuit board 42 is distributed There are devices such as mos tubes, which are connected to the battery 24, and the circuit board 42 is connected to a push switch extending outside the cigarette rod 1. The user can activate the heating function of the induction coil 31 and the metal heating tube 32 by triggering the push switch.

[0077]There are three NTC sensors 33 bonded and fixed to the inner wall of the cigarette rod 1 , corresponding to three induction coils 31 evenly spaced along the axial direction, and used to detect the temperatures of the three induction coils 31 . And on the tobacco rod 1, there is a soot outlet 4 connected with the internal passage of the metal heating pipe 32, and a plug 41 is inse...

Embodiment 3

[0080] refer to Image 6 The difference between this embodiment and Embodiment 1 is that the control module 22 includes an MCU and a switch group, and there are three switch groups, corresponding to three groups of induction coils 31, which include a third switch element and a fourth switch element. Taking one of them as an example, the third switching element includes Image 6 In the transistor Q3, the fourth switching element includes Image 6 The transistor Q4, the transistor Q3, and the transistor Q4 all adopt NPN type transistors.

[0081] A step-up transformer is coupled to the induction coil 31, namely Image 6 In T1, T2 and T3, the high-voltage side coil of the step-up transformer is the induction coil 31. Each step-up transformer has two sets of low-voltage side coils. One end of a set of low-voltage side coils is connected to the positive VBAT terminal of the power supply. The low-voltage side coil The other end is grounded through the transistor Q3, one end of th...

Abstract

The invention relates to an electronic cigarette based on an electromagnetic temperature control technology and a control method thereof. The electronic cigarette comprises a cigarette rod and further comprises a power supply device and an atomizer which are arranged in the cigarette rod. The atomizer comprises an induction coil connected with the power supply device and a metal heating tube arranged in the induction coil in a penetrating mode, wherein tobacco products are placed in the metal heating tube. The power supply device is used for outputting changing current to the induction coil. The electronic cigarette has the advantages that tobacco products are evenly heated, the taste is improved, and the use experience is improved.

Description

technical field [0001] The present application relates to the field of electronic cigarettes, in particular to an electronic cigarette based on electromagnetic temperature control technology and a control method thereof. Background technique [0002] E-cigarettes are a substitute for cigarettes, which generate smoke by means of electronically atomized e-liquid, and can achieve a similar effect to the smoke produced by burning paper cigarettes. The electronic cigarette is mainly composed of an airflow monitor, a control module, an atomizing head, and a lithium battery. When smoking, the control chip can monitor the air flow. At this time, the temperature of the atomizing head is controlled to atomize the e-liquid and generate simulated smoke. [0003] At present, the way to control the temperature rise of the atomizing head mainly adopts IQOS, that is, heat-not-burn technology. Traditional cigarettes have to burn at 600°C or above, and produce smoke and soot during the burni...
