  • the contact points need to be reserved, the heating mode not only has complex assembly, but also has the risk of liquid leakage. In addition, the resistances of the contact points are existed, which makes the heating efficiency low.
  • the non-contact heating generally adopts electromagnetic induction to generate eddy currents for heating.

  • the present disclosure further provides a heating control method for an electronic atomization device, including:
  • the implementation of the present disclosure provides the following beneficial effects: since the atomization body is provided with a first coil, and the atomizer is provided with a second coil, and the first coil conducts electric energy to the second coil through inductive coupling, the atomizer and the atomization body no longer need to be provided with contact points for electrical connection, therefore, the liquid leakage phenomenon of the atomizer is effectively improved compared with the traditional contact (i.e., the atomizer and the atomization body are connected through the contact points) conduction of the electric energy; and the heating efficiency is greatly improved compared with the traditional non-contact conduction of the electric energy.
  • FIG. 3 shows an electronic atomization device in a first embodiment in the present disclosure.

  • the second coil 21 is an inductance coil, and has two endpoints, that is, the second coil 21 is also an inductance coil composed of a common wound coil, and has a small internal resistance.
  • the electronic atomization device in the embodiment further includes a heating member 22, which includes but is not limited to a heating wire or a ceramic heating core, and is connected to the two endpoints of the second coil 21. Alternatively, at least a portion of the heating member 22 may be disposed in the aerosol producing substrate.

  • the atomizer and the atomization body no longer need to be provided with the contact points for electrical connection. Therefore, compared with the traditional contact (i.e., the atomizer and the atomization body are connected through the contact points) conduction of the electric energy, the liquid leakage phenomenon of the atomizer of the electronic atomization device in the embodiment can be effectively improved. Compared with the traditional non-contact conduction of the electric energy, the heating efficiency of the electronic atomization device in the embodiment can be greatly improved.

  • one magnetic conductive medium (such as the magnetic conductive rod 30) is provided between the two coils, which can increase the inductive conduction efficiency.
  • FIG. 4 is the structural diagram of the electronic atomization device in the second embodiment of the present disclosure.
  • the difference of the electronic atomization device of this embodiment is: the second coil 21' is a resistance coil wound by a heating wire, and has a relatively large internal resistance, and the two ends of the second coil 21' are short circuited, for example, the two ends of the second coil 21' are connected through a metal wire 22' (such as a gold wire) with a very small internal resistance, or, the two ends of the second coil 21' are directly connected together.
  • the heating wire is wound into a coil to form the second coil 21', with two ends short circuited.
  • the second coil 21' is arranged around a periphery of the aerosol producing substrate.
  • the electric energy is transferred to the second coil 21' according to the principle of mutual inductance, which will generate induced current on the second coil 21', and the second coil 21' will generate heat due to short circuit, so as to realize the heating and atomizing of the aerosol producing substrate.
  • the magnetic conductive rod 30 is a magnetic conductive rod with a specific Curie point temperature, and the specific Curie point temperature is less than or equal to the dry burning temperature of the aerosol producing substrate.
  • the magnetic conductive rod 30 is a magnetic conductive rod with a Curie point temperature of 280 °C.
  • the magnetic conductive rod has the characteristic that the magnetic conductive performance disappears when the temperature rises to the Curie point temperature.
  • the temperature of the heating member/wire is too high, the temperature of the magnetic conductive rod 30 extending through the heating member/wire will rise according to the conductivity of the thermal energy.
  • a magnetic conductive rod with a Curie point temperature of 280 °C may be selected.
  • the temperature of the magnetic conductive rod will exceed the Curie point temperature, therefore the magnetic conductive performance of the magnetic conductive rod will be greatly weakened, and the electromagnetic induction intensity of the magnetic conductive rod will be correspondingly weakened, and thus the induced current flowing through the heating member/wire will be reduced, which is not enough to provide the required power output, thereby achieving an anti-dry burning effect.

  • the heating control method in this embodiment adopts inductive coupling to conduct electric energy, so that the contact points for electrical connection are no longer needed on the atomizer and the atomization body. Therefore, compared with the traditional contact conduction of the electric energy, the liquid leakage phenomenon of the atomizer can be effectively improved; compared with the traditional non-contact conduction of the electric energy, the heating efficiency of the electronic atomization device in the embodiment can be greatly improved.
  • the electronic atomization device may be either a split electronic atomization device or an integrated electronic atomization device.
