[0024] like Figure 1 , Figure 2 , Figures 4 to 6 As shown, an embodiment provides an atomizing device, including a housing 110, an inner shell assembly 200, and an atomizing unit 222. The housing 110 may include a shell body 111 and an assembly tube 112. The assembly tube 112 is disposed in the shell body 111 at a distance from the inner wall of the shell body 111, extending along the length of the shell body 111. A liquid storage cavity 113 is formed at the interval between the assembly tube 112 and the shell body 111, and the liquid storage cavity 113 is disposed around the periphery of the assembly tube 112. The liquid storage cavity 113 can be used to hold the atomizing matrix. Additionally, the assembly tube 112 is equipped with a first guide structure 114.

[0025] In some embodiments, the inner shell assembly 200 can be inserted into the assembly tube 112 along the axial direction. The inner shell assembly 200 is provided with a second guide structure 215 adapted to the first guide structure 114, and the second guide structure 215 can be guided and positioned with the first guide structure 114. Under the cooperative action of the first guide structure 114 and the second guide structure 215, the outer side of the inner shell assembly 200 can be axially limited to the inner side of the assembly tube 112, and the inner shell assembly 200 can be moved along the axial direction of the assembly tube 112 to be inserted and installed into the assembly tube 112.

[0026] In some embodiments, at least a portion of the atomizing unit 222 is disposed within the inner housing assembly 200. Furthermore, the atomizing unit 222 is in liquid-path communication with the liquid storage chamber 113. During use, the atomizing unit 222 can obtain the atomizing matrix from the liquid storage chamber 113.

[0027] In this embodiment, a first guide structure 114 and a second guide structure 215 are provided between the inner shell assembly 200 and the assembly tube 112. During the assembly process of the atomizing device, the first guide structure 114 and the second guide structure 215 can achieve rapid and accurate alignment between the inner shell assembly 200 and the assembly tube 112, thereby achieving rapid and accurate alignment between the inner shell assembly 200 and the outer shell 110. This improves the installation efficiency of the inner shell assembly 200, and consequently improves the assembly efficiency of the atomizing device, increasing production capacity.

[0028] like Figures 1 to 3 As shown, in some embodiments, the atomizing device further includes a nozzle 130, which can be connected to one end of the housing body 111. In some embodiments, the nozzle 130 and the housing body 111 can be an integral structure. Additionally, an output port 131 can be provided at the end of the nozzle 130 away from the housing body 111. In an embodiment, the atomizing unit 222 is configured with an atomizing channel 2224, one end of which can communicate with the nozzle 130, allowing the user to inhale the aerosol through the output port 131.

[0029] In some embodiments, the end of the assembly tube 112 facing the nozzle 130 can be integrally formed with the housing body 111, and the end of the liquid storage cavity 113 facing the nozzle 130 can form a closed structure without any assembly gap. This improves the sealing performance of the end of the liquid storage cavity 113 facing the nozzle 130, preventing leakage.

[0030] In some embodiments, the nozzle 130 and the shell body 111 can also be separate structures, and the nozzle 130 can be connected to one end of the shell body 111 by means of snap-fit, adhesive or screw connection. In addition, the end of the assembly tube 112 facing the bottom shell 120 can be integrally connected to the shell body 111.

[0031] like Figures 2 to 7 As shown, in some embodiments, the shell body 111 has an opening 1111 at the end away from the nozzle 130. The inner shell assembly 200 can be inserted into the shell 110 from the opening 1111 end of the shell body 111, and can be inserted into the assembly tube 112 axially.

[0032] In some embodiments, the atomizing device further includes a bottom shell 120, which may cover the opening 1111 of the shell body 111 and be connected to the shell body 111. In some embodiments, the bottom shell 120 and the shell body 111 may be connected by means of snap-fit, adhesive or interference fit.

[0033] In some embodiments, the inner shell assembly 200 may include a first support 210. The first support 210 may be inserted into the assembly tube 112 axially. The first support 210 may include an integral body structure 211 and a base plate 212. The body structure 211 may be generally tubular. The base plate 212 may be connected to one end of the body structure 211 facing the bottom shell 120 and cooperates with the body structure 211 to define a receiving cavity 214. In some embodiments, a second guide structure 215 may be formed in the body structure 211.

[0034] In some embodiments, the first guide structure 114 may include a first guide portion 1141 and a third guide portion 1142. The first guide portion 1141 and the third guide portion 1142 may be disposed on opposite sides of the assembly tube 112 along the width direction of the assembly tube 112, and the first guide portion 1141 and the third guide portion 1142 may be configured as an asymmetrical structure. For example, the cross-sectional shape of the first guide portion 1141 perpendicular to the axial direction of the atomizing device may be different from the cross-sectional shape of the third guide portion 1142 perpendicular to the axial direction of the atomizing device.

[0035] In some embodiments, the second guide structure 215 may include a second guide portion 2151 and a fourth guide portion 2152. The second guide portion 2151 may be inserted into and connected to the first guide portion 1141 along the axial direction of the assembly tube 112, and the fourth guide portion 2152 may be inserted into and connected to the third guide portion 1142 along the axial direction of the assembly tube 112. This allows the first bracket 210 to move along the axial direction of the assembly tube 112, and allows the first bracket 210 and the assembly tube 112 to be circumferentially limited along the inner side of the assembly tube 112.

[0036] In this embodiment, when the inner shell assembly 200 is installed on the assembly tube 112, the alignment of the second guide portion 2151 with the first guide portion 1141 and the fourth guide portion 2152 with the third guide portion 1142 can be used to achieve rapid and accurate alignment between the inner shell assembly 200 and the assembly tube 112. Then, the inner shell assembly 200 can be inserted into the assembly tube 112, with the second guide portion 2151 and the first guide portion 1141 axially connected, and the fourth guide portion 2152 and the third guide portion 1142 axially connected. Simultaneously, the first guide portion 1141 and the second guide portion 2151 are circumferentially limited along the inner side of the assembly tube 112, and the fourth guide portion 2152 and the third guide portion 1142 are circumferentially limited along the inner side of the assembly tube 112, preventing relative rotation between the inner shell assembly 200 and the assembly tube 112 during and after assembly.

[0037] In some embodiments, along the width direction of the assembly tube 112, a portion of one sidewall of the assembly tube 112 is configured as an arc shape and serves as a first guide portion 1141. Along the width direction of the assembly tube 112, a portion of the sidewall of the assembly tube 112 on the side away from the first guide portion 1141 is configured as a straight plate shape and serves as a third guide portion 1142. Correspondingly, the cross-sectional shape of the assembly tube 112 perpendicular to its axial direction can be similar to a racetrack shape.

[0038] In some embodiments, along the width direction of the assembly tube 112, a portion of the sidewall on one side of the body structure 211 is configured as an arc shape adapted to the first guide portion 1141 and serves as the second guide portion 2151. Along the width direction of the assembly tube 112, a portion of the sidewall on the side of the body structure 211 away from the second guide portion 2151 can be configured as a straight plate shape adapted to the third guide portion 1142 and serves as the fourth guide portion 2152. That is, the cross-sectional shape of the body structure 211 perpendicular to the axial direction of the assembly tube 112 can also be similar to a racetrack shape and similar to the cross-sectional shape of the assembly tube 112 perpendicular to the axial direction of the assembly tube 112. Therefore, when the inner shell assembly 200 is installed on the assembly tube 112, rapid and accurate alignment of the inner shell assembly 200 and the assembly tube 112 can be achieved. After assembly, the inner shell assembly 200 and the assembly tube 112 can be positioned circumferentially above the atomizing device to prevent relative rotation.

[0039] In some embodiments, one of the first guide portion 1141 and the second guide portion 2151 may be configured as a first guide groove parallel to the axial direction of the assembly tube 112, and the other may be configured as a first guide protrusion adapted to the first guide groove. The first guide protrusion may be inserted into the first guide groove along the axial direction of the assembly tube 112. One of the third guide portion 1142 and the fourth guide portion 2152 may be configured as a second guide groove parallel to the axial direction of the assembly tube 112, and the other may be configured as a second guide protrusion adapted to the second guide groove. The second guide protrusion may be inserted into the second guide groove along the axial direction of the assembly tube 112. The cross-sectional shape of the first guide protrusion is different from that of the second guide protrusion, wherein the cross-sections of both the first and second guide protrusions are perpendicular to the axial direction of the assembly tube 112.

[0040] In some embodiments, the first guide structure 114 may include a first guide portion 1141, and the second guide structure 215 may include a second guide portion 2151. One of the first guide portion 1141 and the second guide portion 2151 may be configured as a first guide groove parallel to the axial direction of the assembly tube 112, and the other may be configured as a first guide protrusion adapted to the first guide groove. The first guide protrusion may be inserted into the first guide groove along the axial direction of the assembly tube 112.

[0041] like Figure 2 , Figures 5 to 7As shown, in some embodiments, the first support 210 further includes a partition 213, which protrudes from the bottom plate 212 on the side facing the receiving cavity 214 and can divide the receiving cavity 214 into a first sub-cavity 2141 and a second sub-cavity 2142. The first sub-cavity 2141 and the second sub-cavity 2142 can be distributed along the width direction of the assembly tube 112. In some embodiments, the atomizing device further includes an electrical unit 221. At least a portion of the structure of the electrical unit 221 can be disposed in the first sub-cavity 2141, and at least a portion of the structure of the atomizing unit 222 can be disposed in the second sub-cavity 2142.

[0042] In some embodiments, the electrical unit 221 may include a power supply battery 2211, which may be disposed in the first sub-chamber 2141.

[0043] In some embodiments, the atomizing unit 222 or the power supply battery 2211 may be disposed in the receiving cavity 214 of the first bracket 210.

[0044] like Figure 2 , Figure 5 and Figure 6 As shown, in some embodiments, the atomizing device further includes a second seal 520, which may be disposed on the side of the inner shell assembly 200 facing the mouthpiece 130. One end of the first bracket 210 facing the second seal 520 is inserted into the second seal 520 and seals with it. That is, one end of the bracket body 311 facing the second seal 520 and one end of the partition 213 facing the second seal 520 are both inserted into the second seal 520 and seal with it. Correspondingly, one end of the first sub-chamber 2141 facing the mouthpiece 130 and one end of the second sub-chamber 2142 facing the mouthpiece 130 can both be sealed by the second seal 520.

[0045] In some embodiments, a first air passage 521 is disposed in the second seal 520, and the first air passage 521 can pass through the second seal 520 substantially along the axial direction of the atomizing device. One end of the first air passage 521 can communicate with the output port 131, and the end of the first air passage 521 away from the output port 131 can communicate with the atomizing channel 2224.

[0046] In some embodiments, the second seal 520 is further provided with a second air passage 522, which extends through the second seal 520 along the axial direction of the atomizing device. One end of the second air passage 522 may communicate with the first sub-chamber 2141, and the other end of the second air passage 522 away from the first sub-chamber 2141 may communicate with the output port 131. The end of the first sub-chamber 2141 away from the second air passage 522 may communicate with the external environment. Additionally, the atomizing device includes a pressure sensor 620, which may be disposed in the second air passage 522. The pressure sensor 620 can be used to detect the user's inhalation action and feed it back to the atomizing unit 222. The atomizing unit 222 can respond to the user's inhalation action to atomize the atomizing matrix to generate an aerosol for the user to inhale. In some embodiments, the pressure sensor 620 may be embedded in the second seal 520.

[0047] like Figure 2 and Figure 5 As shown, in some embodiments, the atomizing unit 222 may include an atomizing tube 2221, a liquid reservoir 2222, and an atomizing core 2223. Both the atomizing core 2223 and the liquid reservoir 2222 are disposed within the atomizing tube 2221, and the liquid reservoir 2222 may be disposed around the periphery of the atomizing core 2223, i.e., the liquid reservoir 2222 may be sandwiched between the atomizing core 2223 and the atomizing tube 2221. The atomizing channel 2224 may penetrate the atomizing core 2223 along the axial direction of the atomizing device. Furthermore, the end of the atomizing channel 2224 facing the mouthpiece 130 may be connected to the end of the first air passage 521 away from the output port 131. The end of the atomizing tube 2221 facing the mouthpiece 130 can be clamped between the first bracket 210 and the second sealing member 520 and sealed against the second sealing member 520, which can achieve the sealing of the connection position between the first air passage 521 and the atomizing channel 2224 and reduce the probability of air leakage.

[0048] In some embodiments, the liquid storage component 2222 may be a structure such as liquid storage cotton, which can be used to temporarily store the atomizing matrix.

[0049] In some embodiments, the end of the atomizing unit 222 away from the nozzle 130 may pass through the base plate 212 and protrude from the side of the base plate 212 opposite to the nozzle 130. The end of the atomizing tube 2221 away from the second seal 520 has an inlet hole 22211 communicating with the liquid storage chamber 113; that is, the inlet hole 22211 may be located on the section of the atomizing tube 2221 protruding from the first support 210 towards the bottom shell 120. Additionally, the heating element of the atomizing core 2223 may be disposed near the end of the inlet hole 22211. The atomizing matrix can enter the atomizing tube 2221 through the inlet hole 22211 and be absorbed and buffered by the liquid storage member 2222. The atomizing core 2223 can obtain the atomizing matrix from the liquid storage component 2222 and heat and atomize the atomizing matrix to generate an aerosol.

In some embodiments, the display module 220 may be a flexible display screen.

[0058] In the embodiments, both the shell body 111 and the assembly tube 112 can be configured as transparent or semi-transparent structures. In some embodiments, the shell 110 as a whole can be made of light-transmitting materials such as glass, polyethylene terephthalate-1,4-cyclohexylene dimethylene terephthalate (PCTG), or polyphenylene sulfone resins (PPSU). Accordingly, both the shell body 111 and the assembly tube 112 are light-transmitting. The shell body 111 as a whole can be used as the first light-transmitting part 1112, and the assembly tube 112 as a whole can be used as the second light-transmitting part 1121.

This reduces the likelihood of the atomizing matrix in the liquid storage chamber 113 entering the space where the display module 220 is located, thus reducing the probability of corrosion damage to the display module 220 due to contact with the atomizing matrix.

[0064] In this embodiment, the bracket body 311 has an annular first embedding groove 2112 on the side facing the assembly tube 112.
