Description

Built-in electromagnetic induction heating atomization core and atomizer using same

Technical Field

The utility model relates to an atomizing core structure of atomizer, in particular to electromagnetic induction heating's that suction-type vapour fog generating device atomizer used atomizing core.

The utility model discloses still relate to the atomizer that uses the suction-type vapour fog generating device of above-mentioned structure atomizing core.

Background

The currently used inhalation type vapor-fog generating device is generally a device for atomizing special liquid by electric heating. The device can be used in the fields of inhalation therapy and the like, but the device is also an inhalation type steam fog generating device commonly called electronic cigarette. The atomizer comprises an atomizer, wherein a heated atomizing component is arranged in the atomizer, the component is called an atomizing core, and most of the atomizing core is heated through a resistance wire.

For example, the atomization core of the traditional structure is provided with a shell of a cylindrical structure, and an oil guide piece and a heating resistance wire are arranged in the shell. The heating resistance wire is in a spiral spring-shaped structure, and a layer of oil guide cotton is coated on the periphery of the heating resistance wire to serve as an oil guide piece. The outer side of the oil guide cotton is provided with an atomizing core shell, and the inner side of the oil guide cotton is provided with a resistance wire. And the upper end of the cylindrical structure of the atomizing core is provided with a vapor outlet which is used for absorbing the atomized vapor along with the airflow. The lower end of the atomizing core is provided with an air inlet for introducing fresh air and forming airflow. The lateral wall of the atomizing core shell is provided with a radial tobacco tar inlet for introducing external tobacco tar. When the atomizing wick is used, the atomizing wick is placed in the tobacco tar, the tobacco tar can enter from the tobacco tar inlet, and then the temperature is increased and the atomization is realized by contacting the oil guide cotton with the heating resistance wire. However, the heating resistance wire of the atomizing core with the structure directly contacts the oil guide cotton and the tobacco tar, and the service life of the heating resistance wire and the oil guide cotton can be influenced. The atomizing core with the structure has the characteristic that the atomizing core can be manufactured into an integral atomizing core for simple replacement.

As industry develops, people use various heating methods on such products, for example, because of the various forms of electric heating, which have both advantages and disadvantages. As an atomizer which has recently come into use and heats in the form of electromagnetic induction, electromagnetic induction heating is performed by making an alternating magnetic field in which a metal object is placed, and the change of the lines of force of the alternating magnetic field generates eddy currents in the metal object, causing the metal material to heat up and heat up. The electromagnetic induction heating mode generally adopts the traditional mode of an external coil for medium-high frequency electromagnetic heating, and the heating component, namely a metal object, is arranged inside the electromagnetic coil. The heated tobacco tar in the electronic cigarette is guided into the oil guide component, the oil guide component is arranged close to the heating component, the heating component is arranged in the electromagnetic coil, and after the electromagnetic coil is electrified with high medium-frequency current, an alternating magnetic field can be generated, so that the heating component made of metal materials in the electromagnetic coil generates eddy current to raise the temperature, and the aim of atomizing the tobacco tar is fulfilled. This is currently a common solution. The disadvantage of this kind of scheme is that the coil is in the periphery, and the inboard sets up a oil guide, and then the inboard is the part that generates heat, still needs to set up the tobacco tar passageway and airflow channel, and this has led to the solenoid and has generated a great deal of distance with the part that generates heat, and a large amount of magnetic flux is unable to pass the part that generates heat, causes energy loss, impairs the heating effect of electromagnetic induction.

Later, an electromagnetic induction heating electronic cigarette atomizing cone with a built-in coil is designed, as shown in fig. 1, the electronic cigarette atomizer with the structure is provided with the built-in electromagnetic coil 36, an induction heating sheet a is arranged outside the electromagnetic coil 36, an oil guide part 21 is arranged outside the induction heating sheet a, and the oil guide part 21 extends into the tobacco tar liquid 22. While the electromagnetic coil 36 is provided with the core 37 and the case 35, the case 35 is housed outside the electromagnetic coil 36, separating the electromagnetic coil 36 from the induction heating chip. However, the electronic cigarette with the structure shown in fig. 1 has the problems that the atomization device is dispersed and the relative position is not scientific, and the atomization effect of the stabilized soil cannot be achieved. For example, the positions of the electromagnetic coil 36 and the heating plate a are not fixed, because the electronic cigarette with such a structure is provided with the electromagnetic coil 36 and the battery as a whole, and belongs to the power supply part, and the heating plate a is integrated with the oil guide and the tobacco tar, i.e. belongs to the smoke bomb part. According to general use habits, the power supply part and the smoke bomb part are assembled for use during use, the relative position of the heating sheet A and the electromagnetic coil 36 cannot be guaranteed to be fixed during assembly, the distance between the electromagnetic coil 36 and the heating sheet A is influenced during radial displacement, the distance and the angle are influenced during axial displacement, and the coaxiality between the heating sheet A and the electromagnetic coil cannot be guaranteed. When the electromagnetic induction heating device is used for heating, the angle and the path through which the magnetic lines of force pass can be changed due to slight changes of the positions of the heating sheet A and the electromagnetic coil 36, so that the heating efficiency can be greatly influenced, and the stability of the atomization effect can be influenced if the distance and the coaxiality of the heating sheet A and the electromagnetic coil 36 are changed.

Meanwhile, as the structure shown in fig. 1 is that the electromagnetic coil 36 and the magnetic core 37 are combined to extend into the tobacco tar storage chamber 22, the oil guiding member 21 leads the tobacco tar out of one end of the tobacco tar storage chamber 22, which inevitably results in uneven supply of the tobacco tar in the axial direction. As shown in fig. 1, the heating plate a is located at the lower half of the oil guiding component, and the smoke oil is guided in from the upper end, so that the smoke oil is unevenly distributed during atomization, the lower end is easy to dry and burn, and the upper end is easy to leak.

In view of the above, the inventor designs a built-in electromagnetic induction heating atomizing core, which is an atomizing core with an integral structure, and the positions of the heating sheet and the electromagnetic coil are fixed, so that the stable atomizing effect can be improved, the middle oil inlet can be realized, and the dry burning and oil leakage phenomena can be avoided.
