[0013] The embodiments of the invention provide an atomization device, and an atomizing matrix used in the atomization device is a heat-not-burn cartridge. The atomization device can use the heat-not-burn cartridge including only a tobacco segment, which saves a hollow cooling segment and a mouthpiece segment in a traditional heat-not-burn cartridge, and reduces the use cost of the heat-not-burn cartridge. Moreover, the atomization device has a plug-in detachable structure, and the heat-not-burn cartridge can be quickly replaced by plug-and-pull, so that the replacement efficiency of the heat-not-burn cartridge can be improved, and the user experience can be improved.

[0014] Please refer to FIGS. 1 to 5, the atomization device according to embodiments of the invention mainly includes a first housing 1, a heating body 2, and a second housing 3. The first housing 1 is fixedly connected with the heating body 2, and the first housing 1 and the heating body 2 form an assembly. The first housing 1 and the second housing 3 are detachably connected with each other. A combination of the first housing 1 and the second housing 3 has 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 while the heating body 2 is plugged into the second housing 3. In the separated state, the first housing 1 and the second housing 3 are separated, while the heating body 2 is pulled out of the second housing 3, and the heating body 2 and the second housing 3 are also separated. The heating body 2 is configured to detachably loaded with an atomizing matrix 7, and the atomizing matrix 7 includes only a tobacco segment of a traditional heat-not-burn cartridge. In the connected state, the atomizing matrix 7 together with the heating body 2 is plugged into the second housing 3, and the user can use it for vaping. In the separated state, the atomizing matrix 7 together with the heating body 2 is separated from the second housing 3, and the atomizing matrix 7 after used can be separated from the heating body 2 to be replaced with a new atomizing matrix 7 for reuse.

[0015] The first housing 1 is a part of an upper cover structure, one end of the first housing 1 is provided with a mouthpiece 11, and another end of the first housing 1 facing away from the mouthpiece 11 is fixedly connected with the heating body 2. The end of the first housing 1 facing away from the mouthpiece 11 may be provided with a convex connection portion 12. The connection portion 12 has a sleeve structure. The connection portion 12 is provided with one or more mounting holes, and each mounting hole is communicated with the mouthpiece 11. One end of the heating body 2 is plugged and fixed into one of the mounting holes of the connection portion 12. Specifically, the heating body 2 may be snapped into the mounting hole of the connection portion 12 by interference fit, or may be fixed into the mounting hole of the connection portion 12 by screw connection.

[0016] In some embodiments, the first housing 1 is provided with the convex connection portion 12, and the connection portion 12 can realize the fixed installation of the heating body 2. Furthermore, the connection portion 12 can be inserted into the inside of the second housing 3 when the first housing 1 and the second housing 3 are connected, so as to realize the position-limiting fixing effect between the first housing 1 and the second housing 3.

[0017] In other embodiments, the another end of the first housing 1 facing away from the mouthpiece 11 may also be provided with a concave connection portion, and the concave connection portion may be a mounting hole structure recessed inward from the end of the first housing 1 facing away from the mouthpiece 11. One end of the heating body 2 is plugged and fixed to the concave connection portion, so that the heating body 2 and the first housing 1 can be fixedly connected, while the heating body 2 and the mouthpiece 11 can be communicated.

[0018] In some embodiments, the heating body 2 is a heating tube, and the heating tube has a heating cavity 21 penetrating the heating tube. The heating cavity 21 is configured to be loaded with the atomizing matrix 7 in a plug-in manner. The heating tube is a metal structure that can be heated to achieve circumferential heating for the atomizing matrix 7 located in the heating cavity 21.

[0019] A depth of the heating cavity 21 is equal to or slightly greater than a length of the atomizing matrix 7. For example, when the length of the atomizing matrix 7 has the range of 10 mm to 14 mm, the depth of the heating cavity 21 may range from 10 mm to 15 mm, so that the entire atomizing matrix 7 can be accommodated in the heating cavity 21, and the heating cavity 21 can realize heating of the entire atomizing matrix 7, which is beneficial to improving the heating atomization efficiency.

[0020] The first housing 1 may be made of plastic or other materials having a heat resistance effect, so as to block the heat generated by the heating body 2 from being transferred to the mouthpiece 11, thereby avoiding scalding the user.

[0021] In some embodiments, the second housing 3 is a main structure of the atomization device. An upper end of the second housing 3 (an end of the second housing 3 facing the first housing 1) is provided with a plug-in groove 31, and the plug-in groove 31 extends into the inside of the second housing 3. An inner diameter and a depth of the plug-in groove 31 are adapted to an outer diameter and a length of the heating body 2, respectively, so that the heating body 2 can be plugged into the plug-in groove 31.

[0022] The depth of the plug-in groove 31 is slightly greater than the length of the heating body 2, so that the connection portion 12 of the first housing 1 and the heating body 2 can be plugged into the plug-in groove 31, so that the first housing 1 and the second housing 3 can be connected by end-face contact, and a better sealing connection effect can be ensured. Furthermore, the heating body 2 can be completely positioned in the plug-in groove 31, thereby facilitating heating of the heating body 2 and heat preservation of the heating body 2, thereby improving heating efficiency.

[0023] In other embodiments, when one end portion of the heating body 2 is plugged into the first housing 1, most of the heating body 2 is located in the plug-in groove 31, so that the atomizing matrix 7 can also be heated.

[0024] In some embodiments, the second housing 3 may include an outer housing 3a and an inner housing 3b. The outer housing 3a is provided with a plug-in port, and the inner housing 3b is a cylindrical structure with one end open and the other end closed. The inner housing 3b partitions a cavity inside the outer housing 3a into the plug-in groove 31 and an accommodating cavity 32. The plug-in groove 31 is aligned and communicated with the plug-in port of the outer housing 3a. The outer housing 3a and the inner housing 3b may be fixedly connected by snap-fitting, screw-connection, or the like, and the outer housing 3a and the inner housing 3b may be formed as an integrated structure.

[0025] An air intake hole is provided at a bottom of the plug-in groove 31, and an air intake port is provided at a bottom or a side surface of the outer housing 3a. The air intake port, the accommodating cavity 32, the air intake hole, and the plug-in groove 31 are communicated in sequence, so that the outside air can enter the heating cavity 21 of the heating body 2, that is, enter inside the atomizing matrix 7.

[0026] In some embodiments, the heating body 2 may be a metal tube that can be heated by electromagnetic induction. An electromagnetic induction coil 4 is provided in the accommodating cavity 32 of the second housing 3, and the electromagnetic induction coil 4 surrounds an outer circumference of the plug-in groove 31. When the heating body 2 is plugged into the plug-in groove 31, the electromagnetic induction coil 4 surrounds an outer circumference of the heating body 2, and after the electromagnetic induction coil 4 is energized, an induction magnetic field is generated to heat the heating body 2, and then the heat energy generated by the electromagnetic induction is transferred from the heating body 2 to the atomizing matrix 7 in the heating body 2, so as to cure the tobacco segment and generate smoke.

[0027] The electromagnetic induction coil 4 may be mounted and fixed to an outer sidewall of the inner housing 3b, that is, the electromagnetic induction coil 4 is fixed to a sidewall of the inner housing 3b located in the accommodation cavity 32. The electromagnetic induction coil 4 is mounted on the outer sidewall of the inner housing 3b, so that the radial and axial alignment of the electromagnetic induction coil 4 and the heating body 2 can be more easily realized, and the heating efficiency of the heating body 2 can be ensured.

[0028] In other embodiments, a mounting bracket may also be provided in the accommodating cavity 32 of the second housing 3 to mount the electromagnetic induction coil 4 on the mounting bracket, and only the electromagnetic induction coil 4 and the plug-in groove 31 need to be aligned radially and axially during mounting.

[0029] In some embodiments, when the electromagnetic induction coil 4 is configured to heat the heating body 2, the air-distance non-contact heating is adopted, at this time, the heating body 2 is non-physically connected with the heating source (i.e., the electromagnetic induction coil 4), so that the heating body 2 can be fixedly connected with the first housing 1 to form an assembly. In other words, the heating body 2 can be inserted in and pulled out of the plug-in groove 31 through the connection and separation between the first housing 1 and the second housing 3, which is convenient for the replacement of the atomization matrix 7.

[0030] In some embodiments, the first housing 1 and the second housing 3 may be fixed by magnetic attraction. A first magnetic attraction portion 13 is provided on an end of the first housing 1 facing the second housing 3, and a second magnetic attraction portion 33 is provided on an end of the second housing 3 facing the first housing 1. The first magnetic attraction portion 13 and the second magnetic attraction portion 33 may be two magnetic blocks having different magnetic properties, so as to realize the fixation between the first housing 1 and the second housing 3 through the mutual magnetic attraction action of the first magnetic attraction portion 13 and the second magnetic attraction portion 33. For example, one of the first magnetic attraction portion 13 and the second magnetic attraction portion 33 is a magnetic block, while the other is a metal block that can be magnetized, which can anyway realize the mutual magnetic attraction between the first magnetic attraction portion 13 and the second magnetic attraction portion 33.

[0031] The first magnetic attraction portion 13 is embedded in an end surface of the first housing 1 facing the second housing 3, or the first magnetic attraction portion 13 is located in the first housing 1 and close to the end surface of the first housing 1 facing the second housing 3. The second magnetic attraction portion 33 is embedded in an end surface of the second housing 3 facing the first housing 1, or the second magnetic attraction portion 33 is located in the second housing 3 and close to the end surface of the second housing 3 facing the first housing 1. The first magnetic attraction portion 13 and the second magnetic attraction portion 33 are aligned with each other, and the first housing 1 and the second housing 3 can be fixed in a plug-and-pull manner by the magnetic attraction force between the first magnetic attraction portion 13 and the second magnetic attraction portion 33.

[0032] The first housing 1 and the second housing 3 are fixed by magnetic attraction, so that the user only needs to bring the first housing 1 and the second housing 3 close to each other to complete the automatic magnetic attraction fixation, which can improve the user's experience of disassembling and assembling the first housing 1 and the second housing 3.

[0033] In other embodiments, the detachably fixed connection between the first housing 1 and the second housing 3 may also be realized by a buckle connection, a screw connection, or the like.

[0034] In some embodiments, the combination of the first housing 1 and the second housing 3 of the atomization device includes a connected state and a separated state.

[0035] Please refer to FIG. 2, when the combination of the first housing 1 and the second housing 3 is in the connected state, the first housing 1 and the second housing 3 are magnetically abutted, the atomizing matrix 7 (including only the tobacco segment) is loaded in the heating cavity 21 of the heating body 2, and the heating body 2 is plugged into the plug-in groove 31 of the second housing 3. In this connected state, the electromagnetic induction coil 4 surrounds the outer circumference of the heating body 2, the electromagnetic induction coil 4 is energized to realize heating of the heating body 2, and the heating of the heating body 2 can perform circumferential baking of the atomizing matrix 7 to generate smoke that can be vaped.

[0036] Referring to FIG. 3, when the combination of the first housing 1 and the second housing 3 is in the separated state, the first housing 1 is separated from the second housing 3, and the first housing 1 brings the heating body 2 to separate from the second housing 3 together. In the separated state, the user can replace the atomizing matrix 7 in the heating body 2, that is, remove the atomizing medium used up for baking, and load a new atomizing matrix 7.

[0037] In the atomization device and electronic atomization apparatus in the embodiments of the invention, since the first housing 1 is connected with the heating body 2, and the first housing 1 is provided with the mouthpiece 11 communicating with the heating cavity 21, the mouthpiece 11 on the first housing 1 can replace the mouthpiece segment in the traditional heat-not-burn cartridge. At the same time, since the mouthpiece 11 is a part of the first housing and is separated from the tobacco segment, the hollow cooling segment in the traditional heat-not-burn cartridge can also be omitted. In this way, the heating cavity 21 of the heating body 2 of the atomization device can be loaded with the atomizing matrix 7 including only the tobacco segment, which greatly reduces the use cost for the user. In addition, the assembly composed of the first housing 1 and the heating body 2 forms a plug-and-pull detachable connection with the second housing 3, which facilitates the replacement of the atomizing matrix 7.

[0038] In some embodiments, an outer wall of the heating body 2 may be provided with one or more heating sheets. The heating sheet may be a resistance heating structure, and the heating sheet can convert electric energy into heat energy. The heating sheet is provided with a first electrical connection contact point, a second electrical connection contact point corresponding to the first electrical connection contact point is provided in the plug-in groove 31 of the second housing 3, and the second electrical connection contact point is connected with the power supply. When the assembly formed by the first housing 1 and the heating body 2 is plugged in and mounted with the second housing 3, the first electrical connection contact point is in contact with the second electrical connection contact point to realize electrical connection, thereby realizing plug-in power supply of the heating sheet. By applying the heating body 2 having the heating sheet, it is also possible to heat and bake the atomizing matrix 7 in the heating body 2.

[0039] In some embodiments, the heating body 2 may be a square tube. Correspondingly, the electromagnetic induction coil 4 is provided in a structure wound along the square tube, and electromagnetic heating of the heating body 2 can also be realized.

[0040] Referring to FIG. 5, in some embodiments, the heating body 2 is a heating tube. One end of the heating tube is connected to the connection portion 12 of the first housing 1, and the other end of the heating tube is provided with a slot 22. The slot 22 extends in an axial direction along an end face of a tube wall of the heating tube, and the slot 22 may extend to a position close to the connection portion 12. The heating tube may be provided with one slot 22, or the heating tube may be provided with a plurality of slots 22, for example with two symmetrical slots 22.

[0041] The heating tube is provided with the slot 22 to make the heating tube have radial elastic ability, so that the heating tube can generate a clamping force to fix the atomizing matrix 7 in the heating cavity 21. Furthermore, the heating tube may be radially expanded to facilitate the removal of the atomizing matrix 7.

[0042] It is naturally appreciated that the heating tube may be provided without the slot 22. Since a volume of the atomizing matrix 7 decreases accordingly after baking, when the atomizing matrix 7 is replaced, the atomizing matrix 7 whose volume is reduced in the heating cavity 21 can also be taken out by swinging with the opening of the heating body 2 facing downward.

[0043] In some embodiments, on the basis that the heating body 2 is provided with the slot 22, the inner diameter of the heating cavity 21 can be set to be slightly less than the outer diameter of the atomizing matrix 7 in the unheated state, so that the atomizing matrix 7 with a relatively larger outer diameter is clamped by the heating body 2 after the heating cavity 21 is loaded with a new unused atomizing matrix 7, so that the atomizing matrix 7 can be more stably mounted in the heating cavity 21, and the atomizing matrix 7 can be avoided from sliding out when the first housing 1 and the second housing 3 are combined and mounted. Furthermore, the heating tube and the atomizing matrix 7 can be fully contacted to improve the heat transmission efficiency, that is, the baking efficiency of the atomizing matrix 7 by the heating tube can be improved.

[0044] Please refer to FIG. 6, in some embodiments, on the basis that the heating body 2 (i.e., the heating tube) is provided with the slot 22, the inner wall of the plug-in groove 31 of the second housing 3 may be provided with one or more radially convex squeezing portions 311. For example, the inside of the plug-in groove 31 is provided with a plurality of semicircular spherical protrusions, or a plurality of convex ribs extending in the axial direction. The convex squeezing portion may have a slightly convex structure. When the heating tube is plugged into the plug-in groove 31, the heating tube is squeezed by the convex squeezing portion 311, so that the atomizing matrix 7 is squeezed by the heating tube in the radial direction. In other words, the heating tube fully contacts the atomizing matrix 7, thereby improving the heat transmission efficiency, that is, improving the baking efficiency of the atomizing matrix 7 by the heating tube.

[0045] In some embodiments, the inner wall of the heating cavity 21 of the heating body 2 may be provided with one or more radially convex limiting portions. For example, the inside of the heating cavity 21 is provided with a plurality of semicircular spherical protrusions or a plurality of convex ribs extending in the axial direction, and the convex limiting portion may be a slightly convex structure. When the atomizing matrix 7 is mounted in the heating cavity 21, the atomizing matrix 7 is squeezed by the convex limiting portion, so that the atomizing matrix 7 is fixed and limited in the heating cavity 21, which can also improve the stability of the mounting and fixing of the atomizing matrix 7.

[0046] Please refer to FIG. 7, in some embodiments, the inner housing 3b has a cylindrical structure, an upper end and a lower end in an axial direction of the inner housing 3b are both provided with one or more mounting portions 34 protruding outward in a radial direction of the inner housing 3b. The mounting portion 34 may be a structure of flange, the electromagnetic induction coil 4 is sleeved on an outer side surface of the inner housing 3b, and the electromagnetic induction coil 4 is limited in the axial direction by the two mounting portions 34. Such arrangement of the mounting portions 34 can realize limiting and mounting of the electromagnetic induction coil 4.

[0047] Please refer to FIG. 8, embodiments of the invention also provide an electronic atomization apparatus. The electronic atomization apparatus includes a circuit board 5, a battery 6, and the atomization device in any of the above embodiments.

[0048] 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 installed in the accommodating cavity 32 of the second housing 3, and the circuit board 5 and the battery 6 are located in different cavities from the heating body 2.

[0049] The circuit board 5 is electrically connected with the battery 6 and the electromagnetic induction coil 4, respectively. The battery 6 is configured to provide electric energy to the circuit board 5 and the electromagnetic induction coil 4. The circuit board 5 is configured to control the electromagnetic induction coil 4 to start and stop heating, and the circuit board 5 can also be configured to control the heating power of the electromagnetic induction coil 4.

[0050] One end of the second housing 3 away from the first housing 1 may also be provided with a charging socket. The charging socket is electrically connected to the circuit board 5, and the charging socket may be connected to a mobile power supply or power nets to supplement electric energy for the battery 6.

[0051] In the electronic atomization apparatus of the embodiments of the invention, since the first housing 1 is connected with the heating body 2, and the first housing 1 is provided with the mouthpiece 11 communicating with the heating cavity 21, the mouthpiece 11 on the first housing 1 can replace the mouthpiece segment in the traditional heat-not-burn cartridge. At the same time, since the mouthpiece 11 is a part of the first housing and is separated from the tobacco segment, the hollow cooling segment in the traditional heat-not-burn cartridge can also be omitted. In this way, the heating cavity 21 of the heating body 2 of the atomization device can be loaded with the atomizing matrix 7 including only the tobacco segment, which greatly reduces the use cost for the user. In addition, the assembly composed of the first housing 1 and the heating body 2 forms a plug-and-pull detachable connection with the second housing 3, which facilitates the replacement of the atomizing matrix 7.

[0052] The above explanations in combination with specific examples of the invention are only used to help understand the invention, and are not intended to limit the invention. For the technical personnel in the technical field to which the invention belongs, it is also possible based on the idea of the invention to conduct several simple deductions, deformations, or replacements.
