Description
Technical Field
The invention relates to the field of atomization equipment, in particular to an electronic atomization device, an atomization main body of the electronic atomization device, an atomizer and a heating control method.
Background
Electronic atomising devices are devices which are capable of atomising the aerosol-forming substrate in an atomiser and have the advantages of being safe, convenient, healthy, environmentally friendly and the like, and are therefore of increasing interest and favor.
Current heating regimes for aerosol-forming substrates are generally divided into contact heating and non-contact heating, of which:
the contact heating is generally to heat the heating wire (or the ceramic is plated with the heating film) directly, and this way needs to reserve two contact points to connect with the heating part circuit. As shown in fig. 1, the heater H1 of the atomizer 20 is in contact with two contact points P1 of the atomizing body 10 through two contact points P2. When the atomizer is in operation, the atomizing body 10 energizes the heating wire H1 through the contact points P1 and P2, the internal resistance of the heating wire H1 is about 1 omega, and the aerosol generating substrate can be atomized after heating. However, since the contact points need to be reserved in the heating mode, the assembly is complex, the leakage risk exists, and in addition, the resistance of the contact points cannot be ignored, so that the heating efficiency is low;
as shown in fig. 2, a winding coil L1 of the atomizing body 10 and a capacitor (not shown) form an LC resonant circuit, the most effective oscillation frequency is achieved by controlling the LC resonant circuit, a metal heating sheet H2 (or a metal heating needle) is placed in the middle of the winding coil L1, and after the winding coil L1 is energized, an eddy current is formed on the surface of the metal heating sheet H2, so as to achieve the purpose of heating. However, when heating by generating eddy current by electromagnetic induction is applied to a small-sized heating element, the heating efficiency is low.

Detailed Description
The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only a part of the embodiments of the present invention, and not all of the embodiments. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention.
Fig. 3 is a schematic diagram of a structure of an electronic atomizer according to an embodiment of the present invention, which includes an atomizing main body 10 and an atomizer 20 detachably connected to each other, and in which a first coil 11 is provided in the atomizing main body 10, and an aerosol-forming substrate is accommodated in the atomizer 20, and a second coil 21 is provided. The first coil 11 is an inductor formed by a common winding coil. The second coil 21 and the first coil 11 are arranged in an up-down manner and coupled to each other. In the state of the nebulizer 20 being mounted to the nebulizing body 10, the first coil 11 generates electromagnetic energy and the second coil 21 extracts energy from the first coil 11 of the nebulizing body 10 by means of inductive coupling to heat the aerosol-forming substrate in the nebulizer 2 and form an aerosol.
In addition, in this embodiment, referring to fig. 3, the second coil 21 is an inductance coil and has two terminals, that is, an inductance composed of a common winding coil, and the internal resistance thereof is small. Furthermore, the electronic atomizer of this embodiment further includes a heat generating body 22, and the heat generating body 22 includes, but is not limited to, a heat generating wire, a ceramic heat generating core, and is connected to both ends of the second coil 21. Further, alternatively, at least a portion of the heat generating body 22 may be disposed in an aerosol-forming substrate. In this embodiment, the first coil 11 is energised to generate electromagnetic energy which, by virtue of mutual induction, is transferred to the second coil 21 to energise the heating element 22 and thereby effect heated atomisation of the aerosol-forming substrate.
In the electronic atomization device of the embodiment, the first coil and the second coil which are coupled are arranged, and the electric energy is conducted in an inductive coupling mode, and a contact point for electrical connection is not required to be arranged on the atomizer and the atomizer main body any more, so that compared with the traditional contact type (the atomizer is connected with the atomizer main body through the contact point) for conducting the electric energy, the liquid leakage phenomenon of the atomizer can be effectively improved; compared with the traditional non-contact type conduction electric energy, the heating efficiency can be greatly improved.
Further, the electronic atomization device of this embodiment further includes a magnetic conductive medium, which may be a magnetic conductive medium made of soft magnetic material, such as the magnetic conductive rod 30. Furthermore, a recess 23 is provided on the connection portion of the atomizer 20 (to achieve the fitting with the atomizer body 10) for accommodating the magnetic rod 30. In addition, the first coil 21 and the second coil 21 are both sleeved on the magnetic conduction rod 30. In this embodiment, a magnetically conductive medium (e.g., a magnetically conductive rod 30) is added between the two coils to increase inductive conduction efficiency.
Fig. 4 is a schematic structural diagram of an electronic atomizer according to a second embodiment of the present invention, which differs from the embodiment shown in fig. 3 only in that: the second coil 21 ' is a resistance coil wound by a heating wire, the internal resistance of which is relatively large, and both ends of the second coil 21 ' are short-circuited, for example, by connecting both ends of the second coil 21 ' through a metal wire 22 ' (such as a gold wire) having a relatively small internal resistance, or by directly connecting both ends of the second coil 21 ' together. In this embodiment, the heating wire is wound into a coil as the second coil 21' and both ends thereof are short-circuited. Further, optionally, the second coil 21' is provided around the periphery of the aerosol-forming substrate. When the first coil 11 is energised to produce electromagnetic energy, and due to the mutual inductance principle, the electrical energy is transferred to the second coil 21 ', an induced current will be generated in the second coil 21', which will generate heat as a result of the short circuit, thereby effecting heating atomisation of the aerosol-forming substrate.
Further, in an alternative embodiment, the magnetically permeable rod 30 is a magnetically permeable rod having a specific curie point temperature, and the specific curie point temperature is equal to or less than the dry-fire temperature of the aerosol-forming substrate, e.g. the magnetically permeable rod 30 is a magnetically permeable rod having a curie point temperature of 280 ℃. In this embodiment, the magnetic conductive rod has a characteristic that the magnetic conductive property disappears when the temperature rises to the curie point temperature; when the aerosol-forming substrate is dry-fired, the heater/filament temperature is too high and, depending on the thermal conductivity, the temperature of the magnetically permeable rod 30 passing through the heater/filament also increases. Assuming that the heating element/wire will be dry-burned when the temperature of the heating element/wire exceeds 280 ℃, a magnetic conducting rod with the curie point temperature of 280 ℃ can be selected, when the aerosol-forming substrate is dry-burned, the temperature of the magnetic conducting rod exceeds the curie point temperature, the magnetic conducting performance of the magnetic conducting rod is greatly weakened, the electromagnetic induction intensity is correspondingly weakened, the induced current flowing through the heating element/wire is also reduced, and the induced current is not enough to provide the required power output, so that the dry-burning prevention effect is achieved, and therefore, the electronic atomization device of the embodiment can not be dry-burned on the premise of not arranging the temperature measurement module.
It should be understood that the above are only specific embodiments of the present invention, and in other embodiments, the arrangement of the first coil and the second coil may further include: arranged left and right and nested concentrically. In addition, the electronic atomization device can be a split type electronic atomization device and also can be an integrated type electronic atomization device.
Fig. 5 is a flowchart of a first embodiment of a heating control method of an electronic atomizer according to the present invention, and with reference to fig. 3 or fig. 4, the heating control method of this embodiment includes:
s10, in a state that the atomizer is installed on the atomization main body, a first coil of the atomization main body generates electromagnetic energy;
and S20, providing energy for a second coil in the atomizer by the first coil in an inductive coupling mode to heat the aerosol forming substrate contained in the atomizer and form aerosol.
In the heating control mode of the embodiment, the electric energy is conducted in an inductive coupling mode, and a contact point for electrical connection is not required to be arranged on the atomizer and the atomizer main body any more, so that compared with the traditional contact type electric energy conduction, the liquid leakage phenomenon of the atomizer can be effectively improved; compared with the traditional non-contact type conduction electric energy, the heating efficiency can be greatly improved.
Furthermore, the electronic atomization device can be a split type electronic atomization device or an integrated type electronic atomization device. Furthermore, the arrangement of the first coil and the second coil may include: arranged up and down, arranged left and right, and nested concentrically. In addition, a magnetically conductive medium, such as a magnetically conductive rod, may be disposed between the first coil and the second coil, the magnetically conductive rod being selected from a magnetically conductive rod having a specific curie point temperature that is less than or equal to the dry-fire temperature of the aerosol-forming substrate.
