BACKGROUND

As a kind of hobby and special merchandise, cigarettes are popular among people. However, tar, carbon monoxide and the like substances contained in the cigarette are hazardous to the health of people. Especially, the tar contains over ten cancer-inducing ingredients, which greatly influence the human health. At present, governments all over the world have gradually prohibited smoking cigarettes (tobaccos) in the public places. However, it is very painful and hard for addicted smokers to never quit cigarettes. Therefore, many cigarette substitutes are emerging in the market, for example, cigarette cessation tablets, electronic cigarettes and the like.

The electronic cigarettes generate smoke by atomizing cartridges, such that users smoke and feel as they are smoking real cigarettes because the electronic cigarettes have a similar appearance as the real cigarettes and create similar taste as the real cigarettes. In addition, since the electronic cigarettes contains no tar, suspension particles and the like hazardous substances, the electronic cigarettes are more and more widely welcomed by the users.

Conventional electronic cigarettes mostly employ nickel-chromium heating element to heat the cartridges.

DETAILED DESCRIPTION

Details are given in the following description for better understanding of the present disclosure. However, the present disclosure may be implemented in a plurality of embodiments different from those described herein, and a person skilled in the art may make similar derivations without departing from the essence of the present disclosure. Therefore, the present disclosure is not subject to limitations by the specific embodiments of the present disclosure disclosed hereinafter.

With respect to the defects mentioned in the background, the present disclosure provides an atomizing device for an electronic cigarette and an electronic cigarette having the same. The present disclosure is described in detail hereinafter with reference to accompanying drawings and exemplary embodiments.

In the present disclosure, the atomizing device includes a housing and an electromagnetic induction heating device disposed in the housing; wherein the electromagnetic induction heating device generates heat based on the law of electromagnetic induction, and thus heats and bakes tobacco materials disposed therein. Therefore, the electromagnetic induction heating device includes electromagnetic induction coils generating a magnetic field, and induction heater generating heat under the effect of the magnetic field. However, the electromagnetic induction coils and the induction heater may be disposed in a plurality of manners. Description is given hereinafter with reference to three embodiments, and a person skilled in the art would make corresponding replacements or modifications based on these three exemplary embodiments.

In an embodiment, referring toFIG. 1,FIG. 1is a schematic structural view of an atomizing device100according to an embodiment of the present disclosure. The atomizing device100according to the embodiment includes a housing11and an electromagnetic induction heating device12.

The shape of the housing11determines the appearance of the atomizing device100. To simulate cigarettes, the housing11is typically disposed to have a cylindrical shape, and correspondingly the electromagnetic induction heating device12disposed in the housing11is also disposed to have an approximately cylindrical shape. Nevertheless, in the embodiment, the housing11may also be defined to a square shape or any other desired shapes. In addition, to prevent impacts caused by the electromagnetic induction heating device12, the housing11is typically not made of a metal material. If the housing11is made of a metal material, an insulating material needs to be disposed between the housing11and the electromagnetic induction heating device12.

The electromagnetic induction heating device12may be filled with tobacco materials. The electromagnetic induction heating device12generates heat based on the law of electromagnetic induction, heats and atomizes the tobacco materials and thus generates smoke, such that users smoke and feel as they are smoking real cigarettes.

In some exemplary embodiments, the electromagnetic induction heating device12includes a plurality of electromagnetic induction coils121and an induction heater122. The electromagnetic induction coils121generate a magnetic field, such that the induction heater121generates a vortex under the effect of the magnetic field, and automatically and quickly generates heat to heat and bake tobacco materials. The induction heater122is made of a metal material.

In the embodiment of the present disclosure, the induction heater122defines a storage chamber123, wherein the tobacco materials are filled in the storage chamber123. The tobacco materials are in direct contact with the induction heater122. When the induction heater122generates heat, the tobacco materials in the storage chamber123are directly heated. In the embodiment, the tobacco material may be tobaccos, cut tobaccos or tobacco liquids.

The electromagnetic induction coils121are disposed on the periphery of the induction heater122, which may be referenced toFIG. 2.FIG. 2is a schematic structural view of an electromagnetic induction heating device in the atomizing device shown inFIG. 1.

The electromagnetic induction coils121may be defined to any shape. In the embodiment, each of the electromagnetic induction coils121is defined to an arc-shaped sheet formed by bending planar coil, and the arc surface of the arc-shaped sheet is adaptive to the shape of the cylindrical-shaped induction heater122. The arc-shaped electromagnetic induction coils121are disposed at a distance from the induction heater122. The induction heater122is at the position with a higher magnetic field strength only when the electromagnetic induction coils121are spaced at a suitable distance from the induction heater122, thereby improving the heating efficiency. In addition, when the electromagnetic induction coils121are disposed at a distance from the induction heater122, the induction coils121are prevented from being damaged by the heat generated by the induction heater122. In some exemplary embodiments, a heat insulating layer13may be further disposed between the electromagnetic induction coils121and the induction heater122.

InFIG. 2(a), two electromagnetic induction coils121are employed and are symmetrically disposed, which may more uniformly heat the tobacco materials in the induction heater122. Nevertheless, the electromagnetic induction coils121may be not symmetrically disposed, and specific disposal depends on the requirement of the shape of the electromagnetic induction heating device12. InFIG. 2(b), four electromagnetic induction coils121are employed, and are respectively disposed along four directions of the periphery of the induction heater122.FIG. 2(b)only illustrates two electromagnetic induction coils121, and correspondingly two additional electromagnetic induction coils121are also disposed. It may thus be concluded that more electromagnetic induction coils121may be disposed in the electromagnetic induction heating device12, which are uniformly disposed along a circumferential direction of the periphery of the induction heater122. It may be understood that the plurality of electromagnetic induction coils121may also be disposed along an axial direction of the induction heater122, and the electromagnetic induction coils may also be disposed based on a combination of these two arrangement modes.

Each of the electromagnetic induction coils121is independently connected to a circuit, such that each electromagnetic induction coil121is capable of independently controlling heat generation. When the plurality of the electromagnetic induction coils121are disposed along the circumferential direction of the periphery of the induction heater122, and according to the actual needs, a part of the electromagnetic induction coils121may be controlled to operate, such that a part of the region on the periphery of the storage chamber123is heated. When the plurality of electromagnetic induction coils121are disposed along the axial direction of the induction heater122, the tobacco materials in the storage chamber123may be heated segmentally according to the actual needs.

In another embodiment, referring toFIG. 3,FIG. 3is a schematic structural view of an atomizing device200according to another embodiment of the present disclosure. In the embodiment, the atomizing device200includes a housing21and an electromagnetic induction heating device22.

The atomizing device200in the embodiment is different from the atomizing device100mainly in that, in the embodiment, the electromagnetic induction heating device22includes a plurality of electromagnetic induction coils221, an induction heater222and a frame223.

The frame223defines a chamber2231, wherein the tobacco materials are filled in the chamber2231, and the induction heater222is disposed on the frame223. In an exemplary embodiment, the induction heater222may be disposed on an outer surface of the frame223, and is configured to conduct heat via the frame223to heat the tobacco materials. In another exemplary embodiment, the induction heater222may be disposed on an inner surface of the frame223, and is in direct contact with the tobacco materials and heat the tobacco materials. In still another exemplary embodiment, the induction heater222may also be nested inside the frame223as a part of the frame223, and is in direct contact with the tobacco materials and heat the tobacco materials. In further exemplary embodiment, the induction heater222may also be disposed within a body of the frame223, and is configured to conduct heat via the frame223to heat the tobacco materials.

The plurality of electromagnetic coils221are disposed on the periphery of the frame223. Therefore, the induction heater222disposed on the frame223may be disposed as to correspond to the electromagnetic induction coils221. For example, if four electromagnetic induction coils221are employed in the embodiment, which are disposed in a way as illustrated inFIG. 2(b)and are respectively disposed at front, rear, left and right parts on the periphery of the frame223, wherein four corresponding induction heaters222are employed and respectively disposed on the frame223and disposed still at the same front, rear, left and right parts.

In some exemplary embodiments, the induction heater222may also be disposed inside the chamber2231, which may be mixed with the tobacco materials and filled into the chamber2231as small-size metals or metal powders, or may be disposed in the chamber2231as a cylindrical sleeve.

The tobacco materials are filled in the first chamber3231, wherein the induction heater322is the same as the induction heater222in the aforesaid embodiment in terms of disposal. The induction heater322may be disposed in the first chamber3231, or may be disposed on the periphery of the first chamber3231. The electromagnetic induction coils321are disposed in the second chamber3232, and surround the first chamber3231, such that the electromagnetic induction coils321may surround the induction heater322. In this way, the frame323may form an integral structure with the induction heater322and the electromagnetic induction coils321.

In the embodiment, the electromagnetic induction coils321and the induction heater322may be integrated using the frame323, wherein the electromagnetic induction heating device32is subjected to a modularized design such that the electronic cigarette having the atomizing device300is more simply to manufacture and install.

In addition, the electromagnetic induction coils321may be integrated with the induction heater322by means of ceramic sintering. In the embodiment of the present disclosure, the first chamber3231and the second chamber3232are not firstly formed. Instead, the electromagnetic induction coils321and the induction heater322are integrated by means of ceramic sintering, and are then packaged by the frame323, such that the first chamber3231and the second chamber3232are automatically formed.
