[0008] Wherein, the liquid-isolating tube can move when the first end is acted upon by an external force, so that the second liquid-transmitting channel is connected with the first liquid-transmitting channel.

[0009] In one embodiment, the first end of the liquid-isolating tube extends out of the atomizing shell from the connecting end;

[0010] The first end can move to a position flush with the connecting end under the action of the jacking force, and the second liquid passage is communicated with the first liquid passage.

[0011] In one embodiment, the atomizer further comprises an elastic member;

[0012] A portion of the elastic member is connected to the liquid isolation tube, and another portion of the elastic member is connected to the atomization shell or the atomization core. The first liquid passage and the second liquid passage are kept in a staggered state under the elastic force of the elastic member.

[0013] In one embodiment, the atomizer further comprises a fixing member, and the liquid-isolating tube comprises a first limiting portion;

[0014] The first limiting portion is arranged in the liquid isolation tube and close to the first end, the fixing piece is sleeved in the liquid isolation tube and connected to the side of the atomization core close to the connecting end, and there is a accommodating cavity between the fixing piece and the liquid isolation tube, and the elastic piece is arranged in the accommodating cavity and abuts between the fixing piece and the first limiting portion.

[0015] In one embodiment, the liquid-isolating tube has a second limiting portion;

[0016] The second limiting portion is disposed at a position of the liquid-isolating tube close to the second end, and the second limiting portion abuts against the atomizer core or the atomizer shell under the action of the elastic force.

[0017] In one embodiment, the atomizing shell further comprises an atomizing head, and the center of the atomizing head and the center of the connecting end are arranged along an axis;

[0018] An atomizing tube connected with the atomizing head is arranged in the atomizing shell along the axis, the atomizing core is connected with the atomizing tube, and the liquid-isolating tube can move in the atomizing shell along the axis.

[0019] According to the second aspect of the present application, an aerosol generating device is provided in one embodiment, comprising:

[0020] The atomizer as described in any of the above embodiments; and

[0021] A power supply component is used to be electrically connected to the atomizer to provide power to the atomizer.

[0022] In one embodiment, the power supply assembly includes a housing and a power supply assembly;

[0023] The power supply assembly is installed in the shell, the shell is provided with a first connecting part, and the atomizer is provided with a second connecting part. When the atomizer is installed in the shell and electrically connected to the power supply assembly, the first connecting part is connected to the second connecting part, and the second liquid passage is communicated with the first liquid passage.

[0028] According to the atomizer in the above embodiment, when the atomizer is not needed, since the second end of the liquid barrier tube is sleeved on the outside of the atomizer core, and the second liquid passage is staggered with the first liquid passage, the first liquid passage on the atomizer core can be blocked by the liquid barrier tube to prevent the aerosol matrix in the liquid storage tank from flowing into the atomizer core. When the atomizer is needed, since the liquid barrier tube is movable in the atomizer shell, the liquid barrier tube can be moved to a position where the second liquid passage is connected to the first liquid passage by applying an external force to the liquid barrier tube at the first end of the liquid barrier tube, so that the aerosol matrix in the liquid storage tank can flow into the atomizer core for atomization. For example, when connecting the atomizer to the power supply assembly, the connection action of the atomizer and the power supply assembly can also be used to move the liquid barrier tube in the atomizer shell, so that the user can connect the liquid storage tank with the first liquid passage without pressing, so that the atomizer core can atomize the aerosol matrix, which is easy to operate and improves the user experience.

[0029] In addition, when the atomizer separates the liquid from the core, it only needs to move the liquid separator without moving the atomizer core, thereby avoiding problems such as deformation of the heating element or poor electrode contact caused by the movement of the atomizer core, thereby ensuring the stability of the atomization of the atomizer.

DETAILED DESCRIPTION

[0041] The present application is further described in detail below by specific embodiments in conjunction with the accompanying drawings. Wherein similar elements in different embodiments adopt associated similar element numbers. In the following embodiments, many detailed descriptions are for making the present application better understood. However, those skilled in the art can effortlessly recognize that some features can be omitted in different situations, or can be replaced by other elements, materials, methods. In some cases, some operations related to the present application are not shown or described in the specification, and this is to avoid the core part of the present application being overwhelmed by too much description, and for those skilled in the art, it is not necessary to describe these related operations in detail, and they can fully understand the related operations according to the description in the specification and the general technical knowledge in the art.

[0042] In addition, the features, operations or characteristics described in the specification can be combined in any appropriate manner to form various embodiments, and the operation steps involved in each embodiment can also be replaced or adjusted in order in a manner that is obvious to those skilled in the art. Therefore, the specification and drawings are only for the purpose of clearly describing a certain embodiment, and do not mean that the composition and / or order are necessary.

[0043] The serial numbers of the components in this document, such as "first", "second", etc., are only used to distinguish the objects described and do not have any order or technical meaning. The "connection" and "coupling" mentioned in this application, unless otherwise specified, include direct and indirect connections (couplings).

[0044] The present application provides an aerosol generating device, such as Figure 1 As shown, the aerosol generating device may include an atomizer 1 and a power supply component 2, and the power supply component 2 may be used to be electrically connected to the atomizer 1 so that the power supply component 2 can provide power to the atomizer 1. The atomizer 1 may be detachably connected to the power supply component 2 by plugging, snapping or magnetic attraction. The atomizer 1 and the power supply component 2 may be assembled to form a columnar, strip-shaped or box-shaped aerosol generating device, and the present application does not impose any special restrictions on the connection method and specific shape between the atomizer 1 and the power supply component 2.

[0045] In order to achieve the function of liquid-core separation, the present application also provides an atomizer 1, such as Figure 2 and Figure 3 As shown, the atomizer 1 may include an atomizing shell 11, an atomizing core 12 and a liquid partition tube 13. The atomizing shell 11 has a connecting end 111 for connecting to a power supply assembly 2. A liquid storage tank 113 is arranged in the atomizing shell 11. The atomizing core 12 is connected in the atomizing shell 11. The atomizing core 12 is provided with a first liquid passage 120. The first liquid passage 120 is used to communicate with the liquid storage tank 113. The liquid partition tube 13 is movably arranged in the atomizing shell 11. The liquid partition tube 13 has a first end 131 and a second end 132. The first end 131 is close to the connecting end 111, and the second end 132 is far away from the connecting end 111 and is sleeved on the outside of the atomizing core 12. The liquid partition tube 13 is provided with a second liquid passage 133. The second liquid passage 133 is staggered with the first liquid passage 120 so that the liquid partition tube 13 blocks the first liquid passage 120. The liquid isolation tube 13 can move when the first end 131 is acted by an external force, so that the second liquid passage 133 is connected to the first liquid passage 120 .

[0046] In this way, when the atomizer 1 is not needed, since the second end 132 of the liquid barrier tube 13 is sleeved on the outside of the atomizer core 12, and the second liquid passage 133 is staggered from the first liquid passage 120, the first liquid passage 120 on the atomizer core 12 can be blocked by the liquid barrier tube 13 to prevent the aerosol matrix in the liquid storage tank 113 from flowing into the atomizer core 12. When the atomizer 1 is needed, since the liquid barrier tube 13 is movable in the atomizer shell 11, the liquid barrier tube 13 can be moved to a position where the second liquid passage 133 is connected to the first liquid passage 120 by applying an external force to the liquid barrier tube 13 at the first end 131 of the liquid barrier tube 13, so that the aerosol matrix in the liquid storage tank 113 can flow into the atomizer core 12 for atomization. For example, when connecting the atomizer 1 and the power supply assembly 2, the connection action of the atomizer 1 and the power supply assembly 2 can also be used to move the liquid isolation tube 13 in the atomization shell 11, so that the user can connect the liquid storage tank 113 with the first liquid passage 120 without pressing, so that the atomization core 12 can atomize the aerosol matrix, which is easy to operate and improves the user experience.

[0047] In addition, when the atomizer 1 is used to separate the liquid from the core, only the liquid separator 13 needs to be moved, without moving the atomizer core 12. This can avoid problems such as deformation of the heating element or poor electrode contact caused by the movement of the atomizer core 12, thereby ensuring the stability of atomization of the atomizer 1.

[0048] The external force on the first end 131 of the liquid barrier tube 13 may be a thrust force or a rotational torque. Correspondingly, the liquid barrier tube 13 may move in a linear manner or in a rotational manner in the atomizing shell 11. The present application does not impose any special restrictions on the movement of the liquid barrier tube 13. The first liquid passage 120 and the second liquid passage 133 may be configured as circular hole shapes or slit shapes. The present application does not impose any special restrictions on the specific shapes of the liquid passage channels.

[0049] It should be noted that the present application will adopt the following methods for hollow components such as channels, cavities, grooves, holes, etc. Figure 2 The first liquid passage 120 and the second liquid passage 133 are marked with arrows, and the remaining components are marked with arrows. The same marking method will be used in the drawings of the following embodiments and will not be repeated.

[0050] In one embodiment, if Figure 3 and Figure 4 As shown, the first end 131 of the liquid isolation tube 13 can extend from the connecting end 111 outside the atomizing shell 11 , and the first end 131 can move to a position flush with the connecting end 111 under the action of the top thrust, and the second liquid passage 133 is connected to the first liquid passage 120 .

[0051] Since the first end 131 of the liquid-isolating tube 13 extends out of the atomizing shell 11 from the connecting end 111, when the atomizer 1 is connected to the power supply assembly 2, the power supply assembly 2 can push the first end 131 of the liquid-isolating tube 13, so that the first end 131 of the liquid-isolating tube 13 moves to a position flush with the connecting end 111 of the atomizing shell 11. Figure 5 As shown, the second liquid passage 133 is just connected to the first liquid passage 120, so that the aerosol matrix in the liquid storage tank 113 can flow into the atomization core 12 for atomization. In this way, the atomizer 1 and the power supply component 2 can automatically start atomization after being connected, simplifying the user's operation.

[0052] Of course, in other embodiments, the first end 131 of the liquid barrier tube 13 may also be disposed inside the connecting end 111 of the atomizing shell 11, and a boss for pushing the liquid barrier tube 13 may be disposed on the power supply assembly 2. When the atomizer 1 is connected to the power supply assembly 2, the boss may also push the liquid barrier tube 13 to move so that the second liquid passage 133 is connected to the first liquid passage 120. In addition, the power supply assembly 2 may also push the liquid barrier tube 13 to move through a magnetic member. The present application does not impose any special restrictions on whether the first end 131 of the liquid barrier tube 13 extends out of the connecting end 111 of the atomizing shell 11.

[0053] In more embodiments, Figures 2 to 5 As shown, the atomizer 1 may further include an elastic member 14, a portion of the elastic member 14 may be connected to the liquid isolation tube 13, and another portion of the elastic member 14 may be connected to the atomization shell 11 or the atomization core 12, and the first liquid passage 120 and the second liquid passage 133 may remain staggered under the elastic force of the elastic member 14.

[0054] In this way, when the atomizer 1 is separated from the power supply component 2, the liquid barrier tube 13 can keep the first liquid passage 120 and the second liquid passage 133 staggered under the elastic force of the elastic member 14, thereby preventing the aerosol matrix from flowing into the atomization core 12, allowing the liquid core to be separated, and preventing the liquid in the liquid storage tank 113 from leaking. When the atomizer 1 is connected to the power supply component 2, the power supply component 2 can drive the liquid barrier tube 13 to overcome the elastic force and move to the position where the first liquid passage 120 and the second liquid passage 133 are connected, so that the aerosol matrix flows into the atomization core 12 for atomization. In this way, the atomizer 1 and the power supply component 2 can achieve the functions of immediate use upon connection and immediate liquid core separation upon disassembly, thereby improving the user experience.

[0055] Among them, the elastic member 14 can be arranged between the liquid-isolating tube 13 and the atomizing shell 11, or between the liquid-isolating tube 13 and the atomizing core 12. The elastic member 14 can be a spring, or a shrapnel, elastic silicone or other elastic material. The present application does not impose any special restrictions on the specific location of the elastic member 14 and the specific material used. In addition, the connection between the elastic member 14 and the atomizing shell 11 or the liquid-isolating tube 13 can be bonding, welding, or abutment, and the present application does not impose any special restrictions on the connection method of the elastic member 14.

[0056] In one embodiment, if Figures 2 to 6 As shown, the atomizer 1 may further include a fixing member 15, the liquid isolation tube 13 may have a first limiting portion 134, the first limiting portion 134 may be arranged in the liquid isolation tube 13 and close to the first end 131, the fixing member 15 is sleeved in the liquid isolation tube 13 and connected to a side of the atomizing core 12 close to the connecting end 111, and a accommodating cavity 16 is provided between the fixing member 15 and the liquid isolation tube 13, and the elastic member 14 is arranged in the accommodating cavity 16 and abuts between the fixing member 15 and the first limiting portion 134.

[0057] The first limiting portion 134 on the liquid isolation tube 13 can be set as a limiting step structure, the fixing member 15 can be set as a T-shaped cylinder structure, and the fixing member 15 is connected and fixed to the atomizing core 12 and then sleeved in the liquid isolation tube 13, so that the recessed part of the fixing member 15 can form a receiving cavity 16 with the liquid isolation tube 13. The elastic member 14 can be a spring, which can be sleeved on the fixing member 15 and installed in the receiving cavity 16, so that the liquid isolation tube 13 can extend out of the connecting end 111 under the elastic force of the spring.

[0058] Of course, in other embodiments, the elastic member 14 may also directly abut between the atomizer core 12 and the first limiting portion 134. However, the setting of the fixing member 15 can not only be used to install the elastic member 14, but the fixing member 15 can also limit and fix the atomizer core 12 to avoid the shaking of the atomizer core 12 during use. In addition, a fixing bracket may be provided in the atomizer 1 to fix the atomizer core 12 and the fixing member 15, so that the atomizer core 12 and the fixing member 15 are more stable. The first limiting portion 134 may also be provided as a baffle or a limiting groove or other structures, or the elastic member 14 may also be directly connected between the liquid isolation tube 13 and the fixing member 15. The present application does not impose any special restrictions on the specific structure of the first limiting portion 134.

[0059] In one embodiment, if Figures 2 to 6 As shown, the liquid-isolating tube 13 may further include a second limiting portion 135 , which may be disposed at a position of the liquid-isolating tube 13 close to the second end 132 , and the second limiting portion 135 abuts against the atomizing core 12 or the atomizing shell 11 under the action of elastic force.

[0060] For example, the second limiting portion 135 can be set as a limiting piece structure at the second end 132 of the liquid-isolating tube 13. When the liquid-isolating tube 13 extends out of the connecting end 111 under the elastic force of the elastic member 14, the liquid-isolating tube 13 can be abutted against the atomizing core 12 through the limiting piece, thereby preventing the liquid-isolating tube 13 from being separated from the atomizing shell 11 from the connecting end 111. Of course, the second limiting portion 135 can also be set as a limiting groove or other structure, and the present application does not impose any special restrictions on the specific structure of the second limiting portion 135.

[0061] In more embodiments, Figure 3 and Figure 5 As shown, the atomizing shell 11 may also have an atomizing head 112, the center of the atomizing head 112 and the center of the connecting end 111 are arranged along the aa axis, an atomizing tube 114 connected to the atomizing head 112 is arranged inside the atomizing shell 11 along the aa axis, the atomizing core 12 can be connected to the atomizing tube 114, and the liquid-isolating tube 13 can move along the aa axis inside the atomizing shell 11.

[0062] The atomizing core 12 may include an atomizing frame, a heating element, an inner cotton packing and other structures, the first liquid passage 120 may be arranged on the atomizing frame, and the atomizing frame may be connected to the atomizing tube 114. In this way, the aerosol atomized by the atomizing core 12 may be discharged from the atomizing tube 114 to the outside of the atomizing head 112. Under the elastic force of the elastic member 14, the liquid-isolating tube 13 may move along the aa axis, thereby facilitating accurate staggering or connection between the second liquid passage 133 and the first liquid passage 120.

[0063] In other embodiments, the atomizer head 112 may also be disposed on the side of the atomizer shell 11 so that the atomized aerosol can be discharged from the side of the atomizer shell 11 . The present application does not impose any special limitation on the location of the atomizer head 112 .

[0064] The above embodiment is a detailed description of the specific structure of the atomizer 1. In order to better demonstrate the content of this application, the following embodiment will provide a detailed description of the connection structure between the atomizer 1 and the power supply assembly 2. Figures 7 to 9 As shown, the power supply component 2 may include a shell 21 and a power supply component 22, the power supply component 22 is installed in the shell 21, the shell 21 may be provided with a first connecting portion 31, and the atomizer 1 may be provided with a second connecting portion 32. When the atomizer 1 is installed in the shell 21 and electrically connected to the power supply component 22, the first connecting portion 31 may be connected to the second connecting portion 32, and the second liquid passage 133 is connected to the first liquid passage 120.

[0065] In this way, through the connection between the first connection part 31 and the second connection part 32, the connection between the atomizer 1 and the power supply assembly 2 can be in place to ensure the communication between the second liquid passage 133 and the first liquid passage 120, so as to avoid the problem of the atomizer 1 being burnt or the atomization effect being unsatisfactory due to the inadequate connection between the atomizer 1 and the power supply assembly 2. In addition, the first connection part 31 and the second connection part 32 can be connected by means of snap-on, plug-in or thread, and the power supply assembly 22 can include electronic components such as power supply batteries, circuit boards, microphones and charging interfaces. The present application does not impose any special restrictions on the connection method between the first connection part 31 and the second connection part 32 and the specific structure of the power supply assembly 22.

[0066] For example, Fig. 9 As shown, the first connection portion 31 may include one of a protrusion and a groove, and the second connection portion 32 may include the other of the protrusion and the groove. When the atomizer 1 is installed in the housing 21, the protrusion can move to a position connected with the groove to connect the first connection portion 31 with the second connection portion 32.

[0067] The protrusion can be arranged on the outer side wall of the atomizer 1, and the groove can be arranged on the inner side wall of the shell 21. When the user connects the atomizer 1 to the power supply assembly 2, the user can judge whether the first connection part 31 and the second connection part 32 are connected in place by the engagement between the protrusion and the groove, which not only improves the user experience, but also ensures the atomization effect. Of course, the protrusion can also be arranged on the inner side wall of the shell 21, and the groove can also be arranged on the outer side wall of the atomizer 1. The present application does not impose any special restrictions on the specific positions of the protrusion and the groove.

[0068] In more embodiments, Figure 6 and Figure 8 As shown, the aerosol generating device may also include a first magnetic component 41 and a second magnetic component 42 that repel each other. The first magnetic component 41 may be arranged on the atomizer 1, and the second magnetic component 42 may be arranged on the power supply component 2. Before the atomizer 1 is electrically connected to the power supply component 2, the liquid isolation tube 13 can move under the action of the repulsive force between the first magnetic component 41 and the second magnetic component 42, so that the second liquid passage 133 is connected to the first liquid passage 120.

[0069] For example, the first magnetic member 41 can be disposed at the first end 131 of the liquid barrier tube 13, and the second magnetic member 42 can be disposed at the end of the power supply assembly 2 close to the atomizer 1. When the user uses the aerosol generating device, before the atomizer 1 and the power supply assembly 2 are arranged relative to each other but not electrically connected, and before the atomizer 1 is turned on, the liquid barrier tube 13 can first move under the repulsive force between the first magnetic member 41 and the second magnetic member 42, so that the second liquid passage 133 is connected to the first liquid passage 120, so that the aerosol matrix can be pre-immersed in the atomizer core 12. In this way, the problem of dry burning of the atomizer core 12 can be avoided when the atomizer 1 and the power supply assembly 2 are electrically connected and the second liquid passage 133 is connected to the first liquid passage 120, because the aerosol matrix is ​​not pre-immersed in the atomizer core 12.

[0070] The above specific examples are used to illustrate the present invention, which are only used to help understand the present invention and are not intended to limit the present invention. For those skilled in the art of the present invention, some simple deductions, deformations or substitutions can be made based on the idea of ​​the present invention.
