Modes for Carrying Out the Invention

[0017] Hereinafter, the present invention will be described in more detail with reference to the accompanying drawings using specific embodiments. Here, similar elements in different embodiments are given the reference numerals of related similar elements. In the following embodiments, many detailed descriptions are made to better understand the present application. However, those skilled in the art can easily recognize that some of these features may be omitted in different situations or replaced by other elements, materials, or methods. In some cases, some operations related to the present application are not shown or described in the specification, which is to avoid being obscured by too much description of the core part of the present application. For those skilled in the art, based on the description in the specification and the general technical knowledge of those skilled in the art, they can fully understand the related operations, so there is no need to describe these related operations in detail.

[0018] Also, the features, operations, or characteristics described in the specification can be combined in any suitable manner to form various embodiments. Also, each step or operation in the description of the method can be changed or adjusted in an obvious manner by those skilled in the art. Therefore, the various sequences in the specification and the drawings are for clearly explaining specific embodiments and do not mean an essential sequence unless otherwise specified.

[0019] In this specification, the numbers themselves attached to components, such as "first", "second", etc., are only used to distinguish the described objects and have no order or technical meaning. In the present application, "connection" and "coupling" include direct connection and indirect connection (coupling) unless otherwise specified.

[0020] In one embodiment, an atomizing device is provided. The atomizing base material used in this atomizing device is a heat-not-burn cartridge, and since this atomizing device can use a heat-not-burn cartridge containing only the tobacco part, the hollow cooling part and the mouthpiece part of the conventional heat-not-burn cartridge are omitted, reducing the usage cost of the heat-not-burn cartridge. Further, this atomizing device has a detachable structure of the plug-in type, and the heat-not-burn cartridge can be quickly replaced by insertion and removal, improving the replacement efficiency of the heat-not-burn cartridge and thus improving the user experience.

[0021] Referring to FIGS. 1 to 5, the atomizing device of this embodiment mainly includes a first housing 1, a heating element 2, and a second housing 3. The first housing 1 and the heating element 2 are fixedly connected to form a single assembly. The first housing 1 and the second housing 3 are detachably connected. The first housing 1 and the second housing 3 have a connected state and a separated state. In the connected state, the first housing 1 and the second housing 3 are butted against each other, and the heating element 2 is inserted into the second housing 3. In the separated state, the first housing 1 and the second housing 3 are separated, and the heating element 2 is pulled out from the second housing 3 and separated from the second housing 3. The heating element 2 is for detachably attaching an atomizing base material 7 that includes only the tobacco part of a conventional heat-not-burn cartridge. In the connected state, the atomizing base material 7 is inserted into the second housing 3 together with the heating element 2, and the user can suck and use it. In the separated state, the atomizing base material 7 is separated from the second housing 3 together with the heating element 2, and it is also possible for the used atomizing base material 7 to be separated from the heating element 2. Thus, it can be replaced with a new atomizing base material 7 and used.

[0022] The first housing 1 belonging to the upper cover structure is provided with a mouthpiece 11 at one end, and the other end opposite to the mouthpiece 11 is fixedly connected to the heating element 2. A protruding connection part 12 is provided at the other end of the first housing 1 opposite to the mouthpiece 11. The connection part 12 has a sleeve structure with a mounting hole communicating with the mouthpiece 11. One end of the heating element 2 is inserted and fixed into the mounting hole of the connection part 12. The heating element 2 may be engaged in the mounting hole of the connection part 12 by a fitting method by press-fitting, or may be fixed in the mounting hole of the connection part 12 by screw connection.

[0023] In this embodiment, a protruding connection portion 12 is provided on the first housing 1. The connection portion 12 can not only fixedly attach the heating element 2, but can also be inserted into the interior of the second housing 3 when connecting the first housing 1 and the second housing 3, thereby realizing the position limitation and fixation between the first housing 1 and the second housing 3.

[0024] In other embodiments, a recessed connection portion may be provided at the other end of the first housing 1 opposite to the suction port 11. The recessed connection portion has the structure of a mounting hole, and one end of the heating element 2 is inserted and fixed into the recessed connection portion, realizing not only the fixed connection between the heating element 2 and the first housing 1, but also the communication between the heating element 2 and the suction port 11.

[0025] In this embodiment, the heating element 2 is a heating tube. The heating tube has a heating chamber 21 penetrating through the heating tube, and the heating chamber 21 is used for inserting and attaching the atomization base material 7 in an insertion manner. The heating tube is a metal structure that can be heated to realize circumferential heating of the atomization base material 7 in the heating chamber 21.

[0026] The depth of the heating chamber 21 is the same as or slightly larger than the length of the atomization base material 7. For example, when the atomization base material 7 is 10 - 14 mm, the depth of the heating chamber 21 is set to 10 - 15 mm, so that the entire atomization base material 7 can be accommodated in the heating chamber 21. The heating chamber 21 can heat the entire atomization base material 7, which is advantageous for improving the heating and atomization efficiency.

[0027] The first housing 1 may be made of plastic or other materials having a heat insulation effect so that the heat of the heating element 2 does not transfer to the suction port 11, which can prevent the user from being burned.

[0028] In this embodiment, the second housing 3 is the main body structure of the atomization device. An insertion groove 31 extending to the interior of the second housing 3 is provided at the upper end of the second housing 3 (the end of the second housing 3 facing the first housing 1). The inner diameter and depth of the insertion groove 31 are adapted to the outer diameter and length of the heating element 2 so that the heating element 2 can be inserted into the insertion groove 31.

[0029] Here, since the depth of the insertion groove 31 is slightly larger than the length of the heating element 2, the connection portion 12 of the first housing 1 and the heating element 2 can be inserted into the insertion groove 31, whereby the first housing 1 and the second housing 3 can be connected such that their end faces are in contact with each other, and a better sealing connection effect can be obtained. Further, since the entire heating element 2 is located within the insertion groove 31, heating of the heating element 2 becomes easier, heat retention of the heating element 2 becomes easier, and the heating efficiency is improved.

[0030] In another embodiment, when a part of one end of the heating element 2 is inserted into the first housing 1, most of the heating element 2 is located within the insertion groove 31, and thereby heating of the atomization base material 7 can also be realized.

[0031] In the present embodiment, the second housing 3 may include an outer housing 3a provided with an insertion port, and an inner housing 3b having a cylindrical structure with one end open and the other end closed, and the inner housing 3b partitions the space within the outer housing 3a into an insertion groove 31 and a storage chamber 32 that communicates with the insertion port of the outer housing 3a in alignment. The outer housing 3a and the inner housing 3b may be fixedly connected by an engagement connection, a screw connection, or the like, or may be an integral structure.

[0032] Among these, an intake hole is provided at the bottom of the insertion groove 31, and an intake port is provided at the bottom or side surface of the outer housing 3a. The intake port, the storage chamber 32, the intake hole, and the insertion groove 31 communicate in sequence, and external air can flow into the heating chamber 21 of the heating element 2, that is, into the atomization base material 7.

[0033] In the present embodiment, the heating element 2 may be a metal tube that can be heated by electromagnetic induction, and an electromagnetic induction coil 4 that surrounds the outer side in the circumferential direction of the insertion groove 31 is provided in the storage chamber 32 of the second housing 3. When the heating element 2 is inserted into the insertion groove 31, the electromagnetic induction coil 4 comes to surround the outer side in the circumferential direction of the insertion groove 31. After the electromagnetic induction coil 4 is energized, it forms an induction magnetic field to heat the heating element 2, and the heat energy generated by the heating element 2 by electromagnetic induction is transmitted to the atomization base material 7 within the heating element 2 to burn the tobacco portion and generate smoke.

[0034] The electromagnetic induction coil 4 may be attached and fixed to the outer wall of the inner housing 3b, that is, fixed to the side wall located in the accommodation chamber 32 of the inner housing 3b. By attaching the electromagnetic induction coil 4 to the outer wall of the inner housing 3b, the alignment of the electromagnetic induction coil 4 and the heating element 2 in the radial direction and the axial direction can be made easier, and the heating efficiency of the heating element 2 can be ensured.

[0035] In another embodiment, a mounting bracket may be provided in the accommodation chamber 32 of the second housing 3, and the electromagnetic induction coil 4 may be attached to the mounting bracket so that the electromagnetic induction coil 4 and the insertion groove 31 are aligned in the radial direction and the axial direction.

[0036] In this embodiment, the heating element 2 is heated using the electromagnetic induction coil 4 to achieve non-contact heating with a gap. Since the heating element 2 does not need to be connected to a heat source, the heating element 2 and the first housing 1 can be fixedly connected to form a single assembly. That is, by connecting and separating the first housing 1 and the second housing 3, the heating element 2 can be inserted into and removed from the insertion groove 31, thereby facilitating the replacement of the atomization base material 7.

[0037] In this embodiment, the first housing 1 and the second housing 3 can be fixed by magnetic adsorption. A first magnetic adsorption portion 13 is provided at the end of the first housing 1 facing the second housing 3, and a second magnetic adsorption portion 33 is provided at the end of the second housing 3 facing the first housing 1. The first magnetic adsorption portion 13 and the second magnetic adsorption portion 33 may be two magnet blocks with opposite polarities, or one of the first magnetic adsorption portion 13 and the second magnetic adsorption portion 33 may be a magnet block and the other may be a metal block that can be magnetically adsorbed. In any case, the first magnetic adsorption portion 13 and the second magnetic adsorption portion 33 can be made to magnetically adsorb to each other.

[0038] The first magnetic adsorption part 13 is fitted to the end face of the first housing 1 facing the second housing 3, or is arranged inside the first housing 1 and provided close to the end face of the first housing 1 facing the second housing 3. Similarly, the second magnetic adsorption part 33 is fitted to the end face of the second housing 3 facing the first housing 1, or is arranged inside the second housing 3 and provided close to the end face of the second housing 3 facing the first housing 1. The first magnetic adsorption part 13 and the second magnetic adsorption part 33 are arranged in alignment with each other, and the first housing 1 and the second housing 3 can be fixed so as to be insertable and removable by the magnetic adsorption force between the first magnetic adsorption part 13 and the second magnetic adsorption part 33.

[0039] The first housing 1 and the second housing 3 are fixed by magnetic adsorption, and when the user brings the first housing 1 and the second housing 3 close to each other, the fixing by magnetic adsorption is automatically completed. Therefore, the user experience of attaching and detaching the first housing 1 and the second housing 3 can be improved.

[0040] In other embodiments, it is also possible to achieve a detachable fixed connection between the first housing 1 and the second housing 3 by means of engagement connection, screw connection, etc.

[0041] In this embodiment, the first housing 1 and the second housing 3 of the atomizing device have a connected state and a separated state.

[0042] Referring to FIG. 2, in the connected state, the first housing 1 and the second housing 3 are connected by magnetic adsorption, the atomizing base material 7 (including only the tobacco part) is mounted in the heating chamber 21 of the heating body 2, and the heating body 2 is inserted into the insertion groove 31 of the second housing 3. In this state, the electromagnetic induction coil 4 surrounds the outer circumferential side of the heating body 2, and the heating body 2 can be heated by energizing the electromagnetic induction coil 4. By heating the heating body 2, the atomizing base material 7 can be baked from the circumferential direction to generate inhalable smoke.

[0043] Referring to FIG. 3, in the separated state, the first housing 1 is separated from the second housing 3, and the first housing 1 separates the heating element 2 and moves away from the second housing 3. In this state, the user can replace the atomization substrate 7 in the heating element 2, remove the used atomization substrate 7 after burning, and attach a new atomization substrate 7.

[0044] In the atomization device and the electronic atomization device of the present embodiment, since the first housing 1 is connected to the heating element 2 and the suction port 11 communicating with the heating chamber 21 is provided in the first housing 1, the suction port 11 in the first housing 1 can replace the suction port part of the conventional heat-not-burn cartridge. Moreover, since the suction port 11 is part of the first housing, it is separated from the tobacco part, and the hollow cooling part of the conventional heat-not-burn cartridge can be omitted. As a result, only the atomization substrate 7 including the tobacco part can be attached to the heating chamber 21 of the heating element 2 of the present atomization device, and the user's usage cost can be significantly reduced. In addition, the assembly composed of the first housing 1 and the heating element 2 and the second housing 3 form a detachable connection of the insertion type, facilitating the replacement of the atomization substrate 7.

[0045] In one embodiment, a heating sheet may be attached to the outer wall of the heating element 2. The heating sheet has a resistive heating structure and can convert electrical energy into thermal energy. The heating sheet is provided with a first electrical connection contact, and a second electrical connection contact corresponding to the position of the first electrical connection contact is provided in the insertion groove 31 of the second housing 3. The second electrical connection contact is connected to a power source. After inserting and attaching the assembly composed of the first housing 1 and the heating element 2 to the second housing 3, the first electrical connection contact and the second electrical connection contact come into contact and are electrically connected, realizing the insertion type power supply of the heating sheet. By using the heating element 2 having a heating sheet, it is also possible to heat and burn the atomization substrate 7 in the heating element 2.

[0046] In one embodiment, the heating element 2 may have a rectangular tubular structure. Accordingly, the electromagnetic induction coil 4 is provided in a structure wound along the rectangular tube, and electromagnetic heating of the heating element 2 can also be realized.

[0047] Referring to FIG. 5, in one embodiment, the heating element 2 is a heating tube. One end of the heating tube is connected to the connection portion 12 of the first housing 1, and a slot 22 extending axially from the end face of the tube wall of the heating tube is provided at the other end of the heating tube. The slot 22 may extend to a position close to the connection portion 12. One slot 22 may be provided in the heating tube, or a plurality of slots 22 may be provided. For example, two symmetric slots 22 may be provided.

[0048] The heating tube is provided with the slot 22 so as to have the ability of elastic deformation in the radial direction, and the heating tube can form a clamping force for fixing the atomization base material 7 in the heating chamber 21. In addition, the heating tube has a configuration that can be expanded in the radial direction, and the removal of the atomization base material 7 can be facilitated.

[0049] Of course, the slot 22 may not be provided in the heating tube. After baking, the volume of the atomization base material 7 shrinks accordingly. Therefore, when replacing the atomization base material 7, by swinging the opening of the heating element 2 downward, the atomization base material 7 with reduced volume in the heating chamber 21 can be taken out.

[0050] In one embodiment, after providing the slot 22 in the heating element 2, the inner diameter of the heating chamber 21 may be set to be slightly smaller than the outer diameter of the atomization base material 7 in the unheated and unused state. Thereby, after mounting the new unused atomization base 7 in the heating chamber 21, the atomization base material 7 with a large outer diameter is clamped by the heating element 2, so that the atomization base 7 can be more reliably mounted in the heating chamber 21. In this way, it is possible to prevent the atomization base material 7 from slipping when the first housing 1 and the second housing 3 are combined, and to sufficiently contact the heating tube and the atomization base material 7 to improve the heat transfer efficiency, that is, to improve the firing efficiency of the atomization base material 7 by the heating tube.

[0051] Referring to FIG. 6, in one embodiment, after slots 22 are provided in the heating element 2 (heating tube), a pressing portion 311 protruding radially may be provided on the inner wall of the insertion groove 31 of the second housing 3. For example, a plurality of semi-spherical protrusions may be provided inside the insertion groove 31, or a plurality of convex ribs extending in the axial direction may be provided. The protruding pressing portion 311 may have a finely protruding structure. When the heating tube is inserted into the insertion groove 31, the protruding pressing portion 311 presses the heating tube, thereby pressing and clamping the atomization base material 7 in the radial direction by the heating tube. That is, the heating tube is brought into sufficient contact with the atomization base material 7, improving the heat transfer efficiency, that is, improving the firing efficiency of the atomization base material 7 by the heating tube.

[0052] In one embodiment, a position limiting portion protruding radially may be provided on the inner wall of the heating chamber 21 of the heating element 2. For example, a plurality of semi-spherical protrusions may be provided inside the heating chamber 21, or a plurality of convex ribs extending in the axial direction may be provided. The protruding position limiting portion may have a finely protruding structure. When the atomization base material 7 is mounted in the heating chamber 21, the protruding position limiting portion presses the atomization base material 7 to limit and fix the atomization base material 7 in the heating chamber 21, and the stability of the mounting and fixing of the atomization base material 7 can also be improved.

[0053] Referring to FIG. 7, in one embodiment, the inner housing 3b has a cylindrical structure, and mounting portions 34 protruding radially are provided at the upper and lower ends in the axial direction of the inner housing 3b. The mounting portions 34 may have a flange structure. The electromagnetic induction coil 4 is fitted on the outer surface of the inner housing 3b, and the electromagnetic induction coil 4 is axially position-limited by the two mounting portions 34. By providing the mounting portions 34, the electromagnetic induction coil 4 can be mounted at a limited position.

[0054] Referring to FIG. 8, in one embodiment, an electronic atomization device is provided, and this electronic atomization device is different from any of the above-described embodiments in that it further includes a circuit board 5 and a battery 6.

[0055] The electronic atomization device of this embodiment includes a circuit board 5, a battery 6, and an atomization device of any of the above-described embodiments.

[0056] The circuit board 5 and the battery 6 are mounted in the second housing 3. Specifically, the circuit board 5 and the battery 6 are mounted in the accommodation chamber 32 of the second housing 3 and are arranged in a chamber different from the heating element 2.

[0057] The circuit board 5 is electrically connected to the battery 6 and the electromagnetic induction coil 4 respectively. The battery 6 is configured to supply power to the circuit board 5 and the electromagnetic induction coil 4. The circuit board 5 is configured to control the on / off of the heating by the electromagnetic induction coil 4, and the circuit board 5 can also control the output of the heating by the electromagnetic induction coil 4.

[0058] A charging socket electrically connected to the circuit board 5 may be provided at the end of the second housing 3 away from the first housing 1. The charging socket can be connected to a mobile power source or a commercial power source to replenish the power of the battery 6.

[0059] In the electronic atomization device of the present embodiment, since the first housing 1 is connected to the heating element 2 and the suction port 11 communicating with the heating chamber 21 is provided in the first housing 1, the suction port 11 in the first housing 1 can be replaced with the suction port of the conventional heat-not-burn cartridge. Also, since the suction port 11 is separated from the tobacco part as a part of the first housing, the hollow cooling part of the conventional heat-not-burn cartridge is also unnecessary, and the atomization base material 7 including only the tobacco part can be attached to the heating chamber 21 of the heating element 2 of the present atomization device, thereby significantly reducing the user's usage cost. Furthermore, the assembly composed of the first housing 1 and the heating element 2 forms a detachable connection of the plug-in type together with the second housing 3, and the replacement of the atomization base material 7 is easy.

[0060] The above description of the present invention using specific examples is for helping the understanding of the present invention and does not limit the present invention. For those skilled in the technical field to which the present invention belongs, based on the idea of the present invention, several simple inferences, modifications or substitutions can be made.
