[0039] In this paper, the serial numbers of components, such as "first", "second", etc., are only used to distinguish the described objects, and have no order or technical meaning. Unless otherwise specified, "connection" and "coupling" in this application include direct and indirect connection (coupling).

[0040] Please refer to Figures 1 to 7 In some embodiments, an atomization device is provided, which includes a first housing 1, an atomization assembly 3, a second housing 2, an electric core 40 and a first sealing piece 5.

[0041] The first housing 1 is provided with a first receiving space and a first mounting groove 101. The atomization assembly 3 is installed in the first receiving space. The second housing 2 is provided with a second receiving space 201 and a second mounting groove 202. The second mounting groove 202 is opposite to the first mounting groove 101. The electric core 40 is installed in the second receiving space 201. The first sealing piece 5 is arranged between the first housing 1 and the second housing 2, and the first sealing piece 5 is embedded in the first mounting groove 101 and the second mounting groove 202 at the same time. The first housing 1 and the second housing 2 are fixedly connected, and the first sealing piece 5 is sealingly matched with the first housing 1 and the second housing 2 respectively. Specifically, the longitudinal dimension of the first sealing piece 5 can be slightly smaller than the sum of the longitudinal dimensions of the first mounting groove 101 and the second mounting groove 202. The longitudinal direction can refer to the direction along the length of the first sealing piece 5 and the first mounting groove 101 and the second mounting groove 202. Figure 4The Y-Y direction in the figure. Due to the size difference in the longitudinal direction, the first seal 5 is pressed in the longitudinal direction when being fitted into the first mounting groove 101 and the second mounting groove 202, so that the first seal 5 expands and deforms in the lateral direction, and the first seal 5 is tightly fitted with the groove walls of the first mounting groove 101 and the second mounting groove 202 respectively.

[0042] The first accommodation space stores an atomized substrate. The electric core 40 is used to provide power, and the electric core 40 is connected with the atomization assembly 3. The atomization assembly 3 generates aerosol by heating and atomizing the atomized substrate in an energized state for a user to inhale.

[0043] Due to the fact that the first seal 5 is embedded in the first mounting groove 101 and the second mounting groove 202 respectively, the first seal 5 is tightly fitted with the first housing 1 and the second housing 2 respectively, and the first seal 5 can be deformed by the pressing force of the first housing 1 and the second housing 2 at the same time, so that the first seal 5 is tightly fitted with the groove walls of the first mounting groove 101 and the second mounting groove 202 respectively, the assembly gap of the first seal 5 with the first housing 1 and the second housing 2 is reduced, thereby having good sealing performance and reducing the risk of leakage of the atomized substrate to the electric core 40.

[0044] As shown in Figure 1 and Figure 2 , in some embodiments, the atomization device further comprises a shell 61 and a mouthpiece assembly 62, and the shell 61 is formed with a receiving cavity. The first housing 1 and the second housing 2 are arranged in the receiving cavity. The mouthpiece assembly 62 is connected with the top of the shell 61, and the mouthpiece assembly 62 and the atomization assembly 3 are in air communication, so as to guide the aerosol generated by the atomization assembly 3 out. A user can inhale the aerosol at the mouthpiece assembly 62. Further, as shown in the embodiments of Figure 1 and Figure 2 , the shell 61 comprises a first unit shell 611 and a second unit shell 612 connected with each other, and the first unit shell 611 and the second unit shell 612 are connected by snap-fit connection.

[0045] As shown in Figure 3 , Figure 5 and Figure 6As shown, in some embodiments, the first housing 1 is provided with a first fastening part 11, and the second housing 2 is provided with a second fastening part 21. The first fastening part 11 is one of a protrusion and a groove, and the second fastening part 21 is the other of a protrusion and a groove. The first housing 1 and the second housing 2 are fastened together by the first fastening part 11 and the second fastening part 21. Thus, the first housing 1 and the second housing 2 are fastened together to fix each other, and together they compress the first sealing member 5, resulting in good sealing performance and easy assembly. During assembly, the first sealing member 5 can be partially inserted into the second mounting groove 202 firstly, and then the first housing 1 containing the atomizing component 3 can be fitted onto the other part of the first sealing member 5, compressing the first sealing member 5 into the first mounting groove 101 of the first housing 1. Finally, the first fastening part 11 and the second fastening part 21 are fastened together, and the first sealing member 5 is compressed and fixed in the first mounting groove 101 and the second mounting groove 202.

[0046] In some embodiments, the first sealing element 5 is an elastic element, characterized by its easy deformation under stress. After the first sealing element 5 is installed into the first mounting groove 101 and the second mounting groove 202, it is compressed between the first housing 1 and the second housing 2 due to the compressive force of the sealing fit. The elastic first sealing element 5 expands laterally after being compressed, resulting in a better sealing effect. The first sealing element 5 can be a silicone part, a rubber part, a silicone rubber part, etc.

[0047] like Figure 7 As shown, in some embodiments, the first housing 1 includes a cylindrical body 12 extending through both ends and a baffle 13 connected to the inner wall of the cylindrical body 12. The baffle 13 defines a first receiving space and a first mounting groove 101 within the space enclosed by the cylindrical body 12. A third mounting groove 102 is formed by recessing the baffle 13 on the side facing the first receiving space towards the first mounting groove 101. The third mounting groove 102 connects the first receiving space and the first mounting groove 101. The atomizing assembly 3 includes an atomizing tube 31, an atomizing core 32, and a heating assembly. The atomizing core 32 is disposed within the space enclosed by the atomizing tube 31. The atomizing tube 31 is embedded in the third mounting groove 102 and fits tightly with the third mounting groove 102. In some embodiments, the atomizing tube 31 and the third mounting groove 102 may be an interference fit to ensure a tight fit.

[0048] The first sealing member 5 has a first end surface 51 facing the atomization tube 31, a second end surface 52 facing away from the atomization tube 31, a through hole 50 penetrating the first end surface 51 and the second end surface 52, and an electrode mounting groove 53 arranged on the second end surface 52. The through hole 50 and the third mounting groove 102 are in communication. The heating assembly has a pin 33, one end of which is connected to the atomization core 32, and the other end of which passes out of the third mounting groove 102 and is fixed in the electrode mounting groove 53 after being partially bent. An electrode is arranged in the electrode mounting groove 53, and the electrode is a metal piece, for example, a gold-plated electrode. The electrode is directly or indirectly connected to the battery cell 40. Thus, the battery cell 40, the electrode, and the pin 33 can form an electrical connection to enable the heating assembly to reach an energized state.

[0049] Specifically, the number of atomization tubes 31 can be one, two, or more. The number of atomization cores 32, the number of third mounting grooves 102, the number of through holes 50, the number of pins 33, the number of electrode mounting grooves 53, and the number of electrodes can be determined according to the number of atomization tubes 31. For example Figures 4 to 7 As shown, in some embodiments, the atomization assembly 3 includes two atomization tubes 31, two atomization cores 32, and two heating assemblies. The atomization core 32, the atomization tube 31, and the heating assembly are one-to-one corresponding. Correspondingly, the number of third mounting grooves 102 is two, the two third mounting grooves 102 and the two atomization tubes 31 are one-to-one corresponding and fixedly embedded; the first sealing member 5 has two through holes 50, the two through holes 50 and the two third mounting grooves 102 are one-to-one corresponding and in communication; each heating assembly has two pins 33, and the two heating assemblies have a total of four pins 33; the first sealing member 5 has four electrode mounting grooves 53; one electrode is arranged in each of the four electrode mounting grooves 53, and a total of four electrodes are arranged. The four pins 33 and the four electrodes are one-to-one corresponding and connected.

[0050] As shown in Figure 4 and Figure 7 As shown, in some embodiments, the atomization device further includes a second sealing member 7 arranged at the opening end of the first receiving space (i.e., the end of the first receiving space away from the first mounting groove 101). The end surface of the second sealing member 7 facing the interior of the first receiving space, the inner wall surface of the first shell 1 facing the atomization tube 31, the surface of the baffle wall 13 facing the second sealing member 7, and the outer peripheral surface of the atomization tube 31 collectively enclose a liquid storage cavity 8. The liquid storage cavity 8 is used to store the atomization substrate. The second sealing member 7 is sealingly matched with the first shell 1 and the atomization tube 31, respectively. In this way, the atomization tube 31 is tightly matched with the third mounting groove 102 on the one hand, and is sealingly matched with the second sealing member 7 on the other hand, so that the internal space of the first shell 1 has good sealing performance, reducing the risk of leakage of the atomization substrate.

[0051] As shown in Figures 3 to 7As shown in the drawings, in some embodiments, the atomization device further comprises a first circuit board 41 connected with the battery 40. The outer side surface 25 of the first shell 1 is provided with a first limiting part 14, the outer side surface 25 of the second shell 2 is provided with a second limiting part 22, and the first circuit board 41 is connected with the first limiting part 14 and the second limiting part 22 at the same time. The atomization device further comprises a display assembly fixed on the first circuit board 41. The display assembly and the first circuit board 41 can form an electrical connection. Thus, the outer side surface 25 of the first shell 1 and the second shell 2 is used as a mounting position 240 of the display assembly, and the mounting area for mounting the display assembly is large, so it is beneficial to install a larger display screen on the atomization device.

[0052] As shown in the drawings, Figure 6 and Figure 7 As shown in the drawings, in some embodiments, the second shell 2 has a side surface 25 and a third end surface 23 facing the first sealing part 5. The third end surface 23 is concavely provided with a second mounting groove 202, and a second receiving space 201 is formed in the side surface 25 of the second shell 2 and provided with a mounting opening 26 for disassembling the battery 40. Specifically, the battery 40 is connected to one side of the first circuit board 41 in the thickness direction. During installation, the first shell 1 and the second shell 2 that are fixed by buckling are used as a whole; the battery 40 and the first circuit board 41 are used as a whole, and the operator only needs to apply a lateral pushing force to push the battery 40 into the second receiving space 201 from the mounting opening 26, the first circuit board 41 is just opposite to the outer side surface 25 of the first shell 1 and the second shell 2, and the first circuit board 41 and the first limiting part 14 and the second limiting part 22 are buckled and fixed to complete the assembly, and the assembly operation is relatively convenient.

[0053] As shown in the drawings, Figures 5 to 7 , Figure 10 As shown in the drawings, in some embodiments, the atomization device further comprises a second circuit board 42. The second shell 2 has a fourth end surface 24 opposite to the third end surface 23, the fourth end surface 24 forms a mounting position 240, and the second circuit board 42 is mounted in the mounting position 240. In some embodiments, the second circuit board 42 is connected with the battery 40 and the first circuit board 41 respectively. During installation, the first shell 1 and the second shell 2 that are fixed by buckling are used as a whole; the battery 40, the first circuit board 41 and the second circuit board 42 are used as a whole, and the operator only needs to apply a lateral pushing force to push the battery 40 into the second receiving space 201 from the mounting opening 26, at the same time, the second circuit board 42 is also pushed into the mounting position 240; the first circuit board 41 is just opposite to the outer side surface 25 of the first shell 1 and the second shell 2, and finally only the first circuit board 41 and the first limiting part 14 and the second limiting part 22 are buckled and fixed to complete the assembly, and the assembly operation is relatively convenient.

[0054] In some embodiments, the electrodes in the electrode mounting groove 53 of the first seal 5 can be connected to the first circuit board 41 and / or the second circuit board 42 via electronic wires.

[0055] like Figure 10 and Figure 11 As shown, in some embodiments, the mounting position 240 is provided with a plurality of protrusions 27 for supporting the second circuit board 42, thereby forming a third receiving space 28 between the fourth end face 24 and the second circuit board 42. This third receiving space 28 can be used to accommodate electronic components 43 on the second circuit board 42. Specifically, the plurality of protrusions 27 are spaced apart, and the edge of the second circuit board 42 abuts against each of the protrusions 27. The fourth end face 24 includes a first surface 241 and a second surface 242. The longitudinal distance between the first surface 241 and the third end face 23 of the fourth end face 24 is greater than the longitudinal distance between the second surface 242 and the third end face 23, that is, the second surface 242 is recessed relative to the first surface 241 towards the third end face 23, making the fourth end face 24 have a stepped structure. The second surface 242 serves as the mounting position 240 for mounting the second circuit board 42. The third receiving space 28 for accommodating electronic components 43 on the second circuit board 42 is defined between the first surface 241 and the second surface 242.

[0056] like Figure 12 As shown, in some embodiments, the atomizing device further includes an air regulating component 90. The second housing 2 is provided with an air inlet 290 communicating with the atomizing component 3. The air regulating component 90 is disposed on the second circuit board 42 and is used to adjust the air intake at the air inlet 290. Specifically, the air inlet 290 is connected to the second receiving space 201, and the air inlet 290 is connected sequentially through the second receiving space 201, the first sealing member 5, and the atomizing component 3. The air inlet 290 is located at the bottom of the second housing 2. The bottom of the outer casing 61 has an opening through which the air regulating component 90 is exposed, thus communicating with the outside atmosphere. Outside air can flow sequentially through the opening, the air regulating component 90, the air inlet 290, the second receiving space 201, the first sealing member 5, and the atomizing component 3. The air regulating component 90 is located between the opening and the air inlet 290, and can adjust the air intake at the air inlet 290 by changing the air intake area, etc.

[0057] like Figure 4 , Figure 7 and Figure 9As shown, in some embodiments, the atomization device further comprises a pneumatic switch 91, and the first sealing member 5 is formed with a pneumatic switch accommodating cavity 54 for installing the pneumatic switch 91. The first shell 1 is further formed with an induction air channel 15 which is in communication with the pneumatic switch accommodating cavity 54. The pneumatic switch 91 is used to control the operation of the atomization assembly 3 in response to the air flow in the induction air channel 15. In some embodiments, the induction air channel 15 is in communication with the mouthpiece assembly 62 at an end thereof which is away from the pneumatic switch accommodating cavity 54, and the pneumatic switch 91 controls the operation of the atomization assembly 3 in response to the suction action of the user. Specifically, the pneumatic switch 91 is in communication connection with the second circuit board 42, and when the pneumatic switch 91 detects the change of the air flow parameter caused by the suction action of the user, it sends a response signal to the second circuit board 42, and the second circuit board 42 controls the operation of the atomization assembly 3 according to the received response signal.

[0058] In some embodiments, the atomization assembly 3 is provided with an atomization channel 30, and the atomization device further comprises a first air channel which is formed on the first sealing member 5 and is in communication with the atomization channel 30. Alternatively, in other embodiments, the first sealing member 5 is formed with a groove 55, and the first air channel is formed between the groove 55 and the second shell 2 and is in communication with the atomization channel 30. Specifically, as shown in Figure 9 In some embodiments, the second end surface 52 of the first sealing member 5 is concavely formed with a groove 55, and the dotted line with arrows shows the path of the air flow along the groove 55. The groove 55 and the bottom surface of the second mounting groove 202 form a spacing space, and the spacing space forms the first air channel. Alternatively, in other embodiments, the groove 55 can also be formed at other positions of the first sealing member 5.

[0059] Specifically, in some embodiments, the lumen of the atomization tube 31 constitutes the atomization channel 30. An end of the first air channel which is away from the atomization channel 30 is in communication with the external atmosphere, so that the external air can enter the atomization channel 30 via the first air channel and carry the aerosol in the atomization tube 31 out to the mouthpiece assembly 62. As shown in Figure 4 In some embodiments, the interior of the second shell 2 is further formed with a third air channel 291 which is in communication with the first air channel and the air inlet 290 respectively, thereby connecting the first air channel and the external atmosphere.

[0060] As shown in Figure 4 , Figure 8 and Figure 9As shown, in some embodiments, the first seal 5 further comprises a second air passage 56, which communicates the sensing air passage 15 and the pneumatic switch accommodating cavity 54. The second air passage 56 is arranged in a meandering manner. Since condensate is prone to be generated at the suction nozzle assembly 62, the condensate is prone to flow back inside the sensing air passage 15. In order to avoid the condensate from affecting the sensitivity and service life of the pneumatic switch 91, the second air passage 56 is designed as a meandering air passage, that is, the extension path of the second air passage 56 from the end connected to the sensing air passage 15 to the end connected to the pneumatic switch accommodating cavity 54 is meandering, which can lengthen the flow-back path of the condensate, intercept part of the condensate in the second air passage 56, and thus reduce the risk of the condensate flowing back to the pneumatic switch accommodating cavity 54.

[0061] The above describes the present application by using specific examples, which is only used to help understand the present application and does not limit the present application. According to the idea of the present application, those skilled in the art of the present application can make some simple deductions, transformations or substitutions.
