[0041] Furthermore, the terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of technical features indicated. Thus, a feature defined as "first" or "second" may explicitly or implicitly include one or more of that feature. In the description of this application, "multiple" means two or more, unless otherwise explicitly specified.

[0042] In this application, unless otherwise expressly specified and limited, the terms "installation," "connection," "linking," and "fixing," etc., should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral part; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; they can refer to the internal communication of two components or the interaction between two components.

[0044] like Figures 1 to 3 As shown, the embodiment provides an atomizing device, including a main unit 1000 and a mouthpiece 2000, wherein the mouthpiece 2000 can be connected to one end of the main unit 1000.

[0045] In some embodiments, the mouthpiece 2000 is provided with a first airway 2110 and a second airway 2120. The main unit 1000 may include a first atomizing unit 100 and a rotatable second atomizing unit 200. The first atomizing unit 100 is provided with a first atomizing channel 101. One end of the first atomizing unit 100 is sealed and inserted into the mouthpiece 2000, and the first atomizing channel 101 communicates with the first airway 2110. Thus, a sealed connection can be achieved between the first atomizing unit 100 and the mouthpiece 2000, preventing air leakage and other problems at the connection point between the first atomizing unit 100 and the mouthpiece 2000, and avoiding affecting the taste of the output aerosol.

[0046] In some embodiments, the second atomizing unit 200 can be rotatably configured relative to the mouthpiece 2000. The second atomizing unit 200 is configured with a plurality of second atomizing channels 201, which are distributed around the rotation axis of the second atomizing unit 200. In an embodiment, at least one second atomizing channel 201 can be in a working position and communicate with the second air passage 2120. Furthermore, the end of the second atomizing unit 200 facing the mouthpiece 2000 is sealed against the mouthpiece 2000, achieving a seal at the connection point between the second atomizing unit 200 and the mouthpiece 2000, preventing air leakage and other problems at the connection point, and avoiding affecting the taste of the output aerosol.

[0047] During use, the first atomizing unit 100 and the second atomizing unit 200 can work separately. For example, the first atomizing unit 100 and the second atomizing unit 200 can work simultaneously without interfering with each other.

[0048] In some embodiments, one of the first atomizing unit 100 and the second atomizing unit 200 may be in an operating state, while the other may be in a standby state.

[0049] In this embodiment, the aerosol generated during the operation of the first atomizing unit 100 can be transported to the first air passage 2110 via the first atomizing channel 101 and then output through the first air passage 2110. The aerosol generated during the operation of the second atomizing unit 200 can be transported to the second air passage 2120 via the second atomizing channel 201 in the working position and then output through the second air passage 2120. Accordingly, users can inhale aerosols composed of multiple flavors or aerosols with a single flavor. In addition, users can rotate the second atomizing unit 200 to output aerosols with different flavors. Thus, diverse user needs can be met.

[0050] like Figure 1 and Figure 2 As shown, in some embodiments, the host 1000 further includes a housing assembly 310. The housing assembly 310 may include a housing 312 and a side cover 311. The housing 312 and the side cover 311 are disposed opposite to each other and cooperate to form an assembly cavity 3101. In some embodiments, the side cover 311 and the housing 312 may be connected by means of snap-fit, adhesive or interference fit.

[0051] In this embodiment, the first atomizing unit 100 and the second atomizing unit 200 are both disposed within the assembly cavity 3101 of the housing assembly 310, and are arranged side by side at the same end within the housing assembly 310. In some embodiments, the first atomizing unit 100 may be disposed near the side cover 311, and the second atomizing unit 200 may be located on the side of the first atomizing unit 100 away from the side cover 311.

[0052] like Figure 1 , Figure 2 , Figure 5 and Figure 6As shown, in some embodiments, the nozzle 2000 may be connected to the end of the housing assembly 310 near the first atomizing unit 100 and the second atomizing unit 200. The nozzle 2000 may include an integral nozzle body 2410 and an insertion portion 2420, with the end of the nozzle body 2410 near the insertion portion 2420 protruding peripherally relative to the insertion portion 2420. A latch 2430 protrudes peripherally from the end of the insertion portion 2420 away from the nozzle body 2410. In embodiments, the insertion portion 2420 may be inserted into the housing assembly 310, and the latch 2430 may engage with the side of the housing assembly 310 facing the assembly cavity 3101. The nozzle body 2410 may protrude from the side of the housing assembly 310 opposite to the assembly cavity 3101 and be confined to that side of the housing assembly 310 opposite to the assembly cavity 3101.

[0053] In some embodiments, the nozzle 2000 may also be connected to the housing assembly 310 by means of interference fit or bonding.

[0054] In some embodiments, both the first airway 2110 and the second airway 2120 can extend through the nozzle body 2410 and the insertion portion 2420 along the axial direction of the atomizing device. When the user uses it for inhalation, the end of the first airway 2110 away from the first atomizing unit 100 and the end of the second airway 2120 away from the second atomizing unit 200 can directly deliver aerosol to the user. The axial direction of the atomizing device can refer to the direction of extension of axis L.

[0055] like Figure 2 and Figure 7 As shown, in some embodiments, the nozzle 2000 further includes a third airway 2130. The end of the first airway 2110 away from the first atomizing unit 100 and the end of the second airway 2120 away from the second atomizing unit 200 are both connected to the third airway 2130. The end of the third airway 2130 away from the first airway 2110 and the second airway 2120 can be used to output aerosol. During use, aerosol passing through the first airway 2110 and aerosol passing through the second airway 2120 can both be output through the third airway 2130.

[0056] like Figure 2 , Figure 3 and Figure 8As shown, in some embodiments, the first atomizing unit 100 includes a first support 110 and an atomizing core 120. The first support 110 is fixedly disposed relative to the housing assembly 310. A liquid storage chamber 1101 is formed on the side of the first support 110 opposite to the nozzle 2000. The liquid storage chamber 1101 can be used to hold a first atomizing matrix, which can be liquid. The atomizing core 120 can be inserted into the first support 110 along the axial direction of the atomizing device and communicates with the liquid storage chamber 1101. The liquid storage chamber 1101 can be arranged around the periphery of the atomizing core 120. In some embodiments, a first atomizing channel 101 can be formed in the atomizing core 120 and can penetrate the atomizing core 120 along the axial direction of the atomizing device.

[0057] During use, the atomizing core 120 can obtain the first atomizing matrix from the liquid storage chamber 1101 and heat and atomize the first atomizing matrix to generate an aerosol. The aerosol can be output from the atomizing device through the first atomizing channel 101 and the first air passage 2110 in sequence.

[0058] In some embodiments, the first atomizing unit 100 further includes a liquid storage component 130 for adsorbing the first atomizing matrix. The liquid storage component 130 can be filled in the liquid storage cavity 1101 and is disposed around the periphery of the atomizing core 120.

[0059] In some embodiments, the liquid storage component 130 may be a structure such as liquid storage cotton.

[0060] like Figure 2 , Figure 3 , Figure 6 and Figure 8 As shown, in some embodiments, a third connecting tube portion 111 protrudes from one end of the first support 110 facing the nozzle 2000, and the third connecting tube portion 111 can be opposite to and communicate with the first atomizing channel 101. A first connecting tube portion 2210 protrudes from the side of the nozzle 2000 facing the main unit 1000, that is, the first connecting tube portion 2210 protrudes from the side of the insertion portion 2420 away from the nozzle body 2410. The first connecting tube portion 2210 can be opposite to and communicate with the first air passage 2110. In the embodiments, the third connecting tube portion 111 can be inserted into the first connecting tube portion 2210 and sealed with the inner wall of the first connecting tube portion 2210 facing the third connecting tube portion 111. Thus, the communication between the first atomizing channel 101 and the first air passage 2110 can be realized, and the connection position between the first atomizing channel 101 and the first air passage 2110 can be sealed.

[0061] In some embodiments, the first connecting tube portion 2210 may also be inserted into the third connecting tube portion 111 and sealed with the inner wall of the third connecting tube portion 111 on the side facing the first connecting tube portion 2210.

[0062] In some embodiments, the main unit 1000 further includes a first sealing member 410, which may be a sealing ring structure. The first sealing member 410 may be disposed around the periphery of the third connecting tube portion 111 and seal against the connection between the first connecting tube portion 2210 and the third connecting tube portion 111. This achieves a seal at the connection point between the first connecting tube portion 2210 and the third connecting tube portion 111. Simultaneously, it also achieves relative fixation between the nozzle 2000 and the first atomizing unit 100.

[0063] In some embodiments, the first connecting pipe portion 2210 and the third connecting pipe portion 111 can also be connected by means of interference fit or bonding, and the connection position can be sealed.

[0064] In some embodiments, the third connecting pipe portion 111 has an annular groove 1111 on the side facing the first connecting pipe portion 2210. The first sealing member 410 can be embedded in the groove 1111, and the side of the first sealing member 410 facing the first connecting pipe portion 2210 can protrude relative to the groove 1111 and seal against the first connecting pipe portion 2210.

[0065] In some embodiments, the first seal 410 may also be embedded in the side of the first connecting tube portion 2210 facing the third connecting tube portion 111. The first seal 410 protrudes from the side of the first connecting tube portion 2210 facing the third connecting tube portion 111, and the protruding side of the first seal 410 relative to the first connecting tube portion 2210 can seal against the third connecting tube portion 111.

[0066] like Figure 2 , Figure 3 , Figure 6 and Figure 8 As shown, in some embodiments, the second atomizing unit 200 may include a second support 210, a rotating support 220, a heating element 230, a carrier element 240, and a second sealing element 250. The second support 210 is arranged side-by-side with the first support 110 on the side opposite to the side cover 311 and is fixedly disposed relative to the housing assembly 310. In some embodiments, the first support 110 and the second support 210 may be an integral structure, thereby improving the compactness of the atomizing device, increasing space utilization, and reducing material costs.

[0067] In some embodiments, a connecting shaft 211 protrudes from one end of the second bracket 210 facing the nozzle 2000, and the connecting shaft 211 may be parallel to the axial direction of the atomizing device. A rotating bracket 220 is rotatably sleeved on the periphery of the connecting shaft 211, and correspondingly, the rotating bracket 220 is rotatably mounted on the side of the second bracket 210 facing the nozzle 2000.

[0068] In some embodiments, the second atomizing unit 200 further includes a limiting member 260. The limiting member 260 may include an integral connecting portion 261 and a limiting portion 262. The limiting portion 262 is connected to one end of the connecting portion 261 and protrudes relative to the periphery of the connecting portion 261. In embodiments, the end of the connecting portion 261 away from the limiting portion 262 may sequentially pass through the rotating bracket 220 and the connecting shaft 211, and be connected to the connecting shaft 211 by means of threaded connection, interference fit, or snap-fit. The limiting portion 262 may be positioned on the side of the rotating bracket 220 opposite to the connecting shaft 211, and may restrict the relative movement of the rotating bracket 220 and the connecting shaft 211 parallel to the axial direction of the atomizing device. Simultaneously, it may ensure that the rotating bracket 220 can rotate smoothly relative to the connecting shaft 211.

[0069] In some embodiments, the rotating support 220 may be configured with four first receiving cavities 221, and the second atomizing unit 200 may also include four carrier members 240. The four carrier members 240 may be disposed in the four first receiving cavities 221 in a one-to-one correspondence.

[0070] In some embodiments, the second atomizing unit 200 may also include two, three, or five carrier members 240. The rotating support 220 may be configured with a number of first receiving cavities 221 equal to the number of carrier members 240. The multiple carrier members 240 are disposed in the multiple first receiving cavities 221 in a one-to-one correspondence.

[0071] In some embodiments, the second atomizing channel 201 may be formed in the carrier 240 and may extend through the carrier 240 along the axial direction of the atomizing device. In the embodiments, a second atomizing matrix may be attached to the carrier 240, wherein the second atomizing matrix may be in the form of granules or the like.

[0072] In some embodiments, the second seal 250 can be sealed and inserted into the end of the rotating bracket 220 facing the nozzle 2000, and the second seal 250 can rotate synchronously with the rotating bracket 220. The second seal 250 may have multiple first through holes 251, which can penetrate the second seal 250 along the axial direction of the atomizing device. In some embodiments, the number of first through holes 251 may be equal to the number of carrier components 240. The side of the first accommodating cavity 221 facing the second seal 250 may be configured as an open structure, and the multiple first through holes 251 may correspond one-to-one with and communicate with the multiple first accommodating cavities 221. Correspondingly, the multiple first through holes 251 may correspond one-to-one with the second atomizing channels 201 in the multiple carrier components 240.

[0073] In some embodiments, a second connecting tube portion 2220 protrudes from the end of the nozzle 2000 facing the main unit 1000, that is, the second connecting tube portion 2220 protrudes from the side of the insertion portion 2420 opposite to the nozzle body 2410. The second connecting tube portion 2220 may be arranged side by side with the first connecting tube portion 2210, and the second connecting tube portion 2220 is located on the side of the first connecting tube portion 2210 opposite to the side cover 311. In addition, the second connecting tube portion 2220 may be opposite to and communicate with the second air passage 2120.

[0074] In some embodiments, one end of the second connecting tube portion 2220 away from the insertion portion 2420 can seal against the end face of the second sealing member 250 facing the nozzle 2000. This achieves a seal at the connection point between the nozzle 2000 and the second atomizing unit 200. Simultaneously, the second sealing member 250 can be pressed against the rotating bracket 220, causing a seal between the rotating bracket 220 and the second sealing member 250, thus sealing the connection between the first through hole 251 and the corresponding second atomizing channel 201, reducing the probability of air leakage.

[0075] In some embodiments, a first sealing ridge 2300 may protrude from one end of the second connecting tube portion 2220 away from the insertion portion 2420. The first sealing ridge 2300 may be annular and surround the periphery of the second connecting tube portion 2220 opening towards the second sealing member 250. The first sealing ridge 2300 may seal against the side of the second sealing member 250 facing the nozzle 2000, thereby further improving the sealing effect at the connection point between the second sealing member 250 and the nozzle 2000.

[0076] In some embodiments, a plurality of first sealing ridges 2300 may protrude from one end of the second connecting tube portion 2220 away from the insertion portion 2420. The plurality of first sealing ridges 2300 may be nested sequentially along the radial direction of the second connecting tube portion 2220. The plurality of first sealing ridges 2300 may all seal against the side of the second sealing member 250 facing the nozzle 2000, thereby extending the sealing path between the nozzle 2000 and the second sealing member 250 and further improving the sealing effect at the connection position between the second sealing member 250 and the nozzle 2000.

[0077] In some embodiments, one of the carrier members 240 in the second atomizing unit 200 may be in a working position.

A first sealing ridge 2300 may be disposed around the periphery of the first through-hole 251, meaning the second atomizing channel 201 in the carrier member 240 may communicate with the second air passage 2120. Simultaneously, the carrier member 240 may be coaxially arranged with the second connecting pipe portion 2220.

[0078] In some embodiments, two or three or more carrier components 240 in the second atomizing unit 200 may be in the working position at the same time.

The second sealing ridge 4221 may seal against the side of the rotating bracket 220 away from the nozzle 2000 to improve the sealing effect between the sealing sleeve 422 and the rotating bracket 220. When one of the carrier components 240 rotates to the working position, the second sealing ridge 4221 may be arranged around the periphery of the opening structure of the first accommodating cavity 221 of the carrier component 240, thereby sealing the position where the heating channel 231 communicates with the second atomizing channel 201 in the carrier component 240 and reducing the probability of air leakage.

[0089] In this embodiment, the second sealing ridge 4221 can also be provided as one, two, three or any other arbitrary number as needed. When multiple second sealing ridges 4221 are provided, the multiple second sealing ridges 4221 can be nested sequentially along the radial direction of the sealing sleeve 422 to increase the sealing path between the sealing sleeve 422 and the rotating bracket 220, and further reduce the probability of air leakage.
