Detailed Description

An embodiment of the present application provides an aerosol-generating device, referring to fig. 1 to 14, comprising a power supply host 10 and a nebulizer (i.e. a first nebulizer 20 in fig. 1 and a second nebulizer 30 in fig. 3).

Referring to fig. 2, 4, 9 and 11, the power supply main unit 10 includes a housing 11 and a body 12, and the housing 11 has a dodging port 11a. The body 12 includes a housing 121 having a mounting groove 121a and a power supply module (not shown) disposed in the housing 121.

The mounting groove 121a is used for mounting the atomizer, and the power supply module is used for supplying power to the atomizer.

The shell 11 is detachably sleeved on the shell 121, the avoiding opening 11a is communicated with the mounting groove 121a, and the avoiding opening 11a and the mounting groove 121a are used for electrically connecting a power supply module with the atomizer.

Specifically, the power supply host 10 may detach the housing 11 to separate the machine body 12 from the housing 11 for independent use, or may detachably sleeve the housing 11 on the casing 121 to enable the housing 11 to be matched with the machine body 12 for use. The power supply host 10 has a first usage pattern and a second usage pattern which are selectable, and the first usage pattern or the second usage pattern can be selected as needed.

Referring to fig. 1, 2, 8 and 9, when the power supply main unit 10 is in the first usage configuration, the power supply main unit 10 removes the housing 11 to separate the main unit 10 from the housing 11 for independent use, that is, in the first usage configuration, the power supply main unit 10 only needs to use the main unit 12 without the housing 11, and the main unit 12 is not installed in the housing 11. Referring to fig. 3, 4, 10 and 11, when the power supply main unit 10 is in the second usage configuration, the housing 11 is detachably sleeved on the casing 121, i.e. the machine body 12 is installed in the housing 11, and the avoiding opening 11a is communicated with the installation groove 121a, i.e. in the second usage configuration, the machine body 12 and the housing 11 are combined together for use, and meanwhile, the housing 11 does not cover the installation groove 121a on the machine body 12.

That is, the housing 11 and the body 12 are of a separable structure, and the body 12 may be mounted in the housing 11 or may be removed from the housing 11.

The shape of the housing 11 is not limited as long as the body 12 can be mounted, and the housing 11 may be, for example, box-shaped as shown in fig. 3 and 4, or rod-shaped as shown in fig. 10 and 11.

For example, the power supply host 10 may be used with two atomizers of different capacities, and the power supply host 10 in a first usage configuration is used with the first atomizer 20, and the power supply host 10 in a second usage configuration is used with the second atomizer 30, for example, referring to fig. 1, 2, 8 and 9, the first atomizer 20 includes a first atomizing assembly (not shown) and a first main body (not shown) having a first accommodating chamber. The first receiving chamber is for receiving an aerosol-generating article, which may be a liquid or a solid. The first atomizing assembly is for heating and atomizing an aerosol-generating article stored within the first receiving chamber.

When the power supply host 10 is in the first use mode, the first atomizer 20 is inserted into the mounting groove 121a, and the first atomizing assembly is electrically connected with the power supply module, so as to supply power to the first atomizing assembly through the power supply module.

Referring to fig. 3, 4, 10 and 11, the second atomizer 30 includes a second atomizing assembly (not shown) and a second body (not shown) having a second receiving chamber. The second receiving chamber is also adapted to receive an aerosol-generating article, the capacity of the second receiving chamber being greater than the capacity of the first receiving chamber, i.e. the second receiving chamber may receive more aerosol-generating article than the first receiving chamber, or alternatively the capacity of the second atomizer 30 is relatively greater than the first atomizer 20. The second atomizing assembly is for heating and atomizing the aerosol-generating article stored within the second receiving chamber.

In the second usage mode of the power supply main unit 10, the second atomizer 30 is inserted into the mounting groove 121a, and the second atomizing assembly is electrically connected with the power supply module, so as to supply power to the second atomizing assembly through the power supply module.

It should be noted that, since the capacity of the second atomizer 30 is relatively large, in general, the external dimension of the second atomizer 30 is also relatively large, but the portion of the second atomizer 30 inserted into the mounting groove 121a and the portion of the first atomizer 20 inserted into the mounting groove 121a may be made to be the same or similar in size, so that the first atomizer 20 and the second atomizer 30 can both meet the mounting requirement of the mounting groove 121a.

Illustratively, the aerosol-generating device may have at least one of the first atomizer 20 and the second atomizer 30 in addition to the power supply host 10, that is, the aerosol-generating device may have the first atomizer 20 without the second atomizer 30, may have the second atomizer 30 without the first atomizer 20, and may have both the first atomizer 20 and the second atomizer 30, as desired, in addition to the power supply host 10.

For an aerosol-generating device having a power supply host 10 and a first atomizer 20 without a second atomizer 30, a user purchases the power supply host 10 and the first atomizer 20 without the second atomizer 30 when purchasing the aerosol-generating device, which corresponds to the power supply host 10 and the first atomizer 20 being combined together for sale as a kit, and if the user needs to use the second atomizer 30, another separate purchase of the second atomizer 30 is required.

For an aerosol-generating device having a power supply host 10 and a second atomizer 30 without a first atomizer 20, a user purchases the power supply host 10 and the second atomizer 30 without the first atomizer 20 when purchasing the aerosol-generating device, which corresponds to the power supply host 10 and the second atomizer 30 being combined together for sale as a kit, and if the user needs to use the first atomizer 20, another purchase of the first atomizer 20 alone is required.

In the case of an aerosol-generating device having a power supply host 10, a first atomizer 20, and a second atomizer 30, when a user purchases the aerosol-generating device, the power supply host 10, the first atomizer 20, and the second atomizer 30 are purchased, which corresponds to the power supply host 10, the first atomizer 20, and the second atomizer 30 being combined together to be sold as a package.

Whether the first atomizer 20 and/or the second atomizer 30 are/is provided in the aerosol-generating device, the first atomizer 20 and the second atomizer 30 may be provided with a separate replaceable unit, which corresponds to the power supply main unit 10 being reusable, and the user may purchase the first atomizer 20 and/or the second atomizer 30 separately for replacement.

It will be appreciated that the use of the power supply main unit 10 in the first usage configuration and the first atomizer 20 as described above is only one possible embodiment, and the use of the power supply main unit 10 in the second usage configuration and the second atomizer 30 is only one possible embodiment, and in other embodiments, the power supply main unit 10 may be used with only one atomizer, and the user may choose whether to install the housing 11 according to his own preference.

That is, the power supply host 10 of the embodiment of the present application is provided with a housing 11 and a body 12, the housing 11 is detachably sleeved on the casing 121 of the body 12, and the avoiding opening 11a of the housing 11 is communicated with the mounting groove 121a on the casing 121, the power supply host 10 can be detached from the housing 11 so that the body 12 is separated from the housing 11 for independent use, and the housing 11 can also be detachably sleeved on the casing 121 so that the housing 11 and the body 12 are used in cooperation, which is equivalent to the power supply host 10 having a first usage form and a second usage form, in which the power supply host 10 is in the first usage form, the power supply host 10 detaches the housing 11 so that the body 12 is separated from the housing 11 for independent use, and in which the power supply host 10 is in the second usage form, the housing 11 is detachably sleeved on the casing 121, i.e. the body 12 is mounted in the housing 11, and the avoiding opening 11a is communicated with the mounting groove 121a. The first usage form and the second usage form of the power supply host 10 may be adapted to atomizers with different capacities respectively, for example, taking the first atomizer 20 and the second atomizer 30 with a larger capacity than the first atomizer 20 as an example, in the first usage form, the body 12 of the power supply host 10 is separately used in cooperation with the first atomizer 20, without using the housing 11, in the second usage form, the body 12 of the power supply host 10 is assembled with the housing 11 and is used in cooperation with the second atomizer 30, thereby, the usage requirement of users on atomizers with different capacities can be met, in addition, because the capacity of the second atomizer 30 is relatively larger, the overall dimension of the second atomizer 30 is also relatively larger, and after the body 12 of the power supply host 10 is assembled with the housing 11, the overall dimension of the power supply host 10 is also relatively larger, therefore, by being used in cooperation with the power supply host 10 with the second usage form, the difference between the second atomizer 30 and the power supply host 10 on the human-machine experience can be reduced.

In an embodiment, referring to fig. 3 to 7 and fig. 10 to 14, the housing 11 may include a housing body 111 and a housing cover 112 having a recess 11a, where the housing cover 112 is detachably connected to the housing body 111. That is, the cover 112 and the body 111 can be separated, and the user can switch the power supply host 10 between the first usage mode and the second usage mode by assembling and disassembling the cover 112 and the body 111, so that the operation is simple and convenient.

In addition, referring to fig. 4 and 11, the avoiding opening 11a is disposed on the cover 112, and in the second usage mode, the user can directly insert the second atomizer 30 into the mounting groove 121a from the avoiding opening 11a, so that the feel and experience are better.

In one embodiment, when the body 12 is mounted in the housing 11, the cover 112 may abut against the body 12. That is, the cover 112 can press the body 12 to limit the body 12, so as to prevent the body 12 from shaking in the housing 11.

In an embodiment, referring to fig. 4 and 11, the housing 111 may also be provided with a limiting groove 111b, and the machine body 12 is installed in the limiting groove 111b, that is, the machine body 12 may also be limited by the limiting groove 111 b.

The cover 112 may be detachably connected to the housing 111 in various manners, for example, the cover 112 and the housing 111 may be detachably connected by a clamping manner, for example, referring to fig. 4, 5 and 12, the cover 112 may include a first connection portion 112a having an avoidance port 11a and a first clamping portion 112b disposed on the first connection portion 112a, a second clamping portion 111a is disposed on an inner wall of the housing 111, and a portion of the first connection portion 112a where the first clamping portion 112b is disposed extends into the housing 111, and the first clamping portion 112b and the second clamping portion 111a are clamped.

Referring to fig. 4, 5 and 12, when the machine body 12 is required to be mounted in the housing 11, only the machine body 12 is required to be placed in the housing 111, then the first connecting portion 112a of the housing cover 112 is required to be inserted into the housing 111, and the first clamping portion 112b and the second clamping portion 111a are required to be clamped, when the machine body 12 is required to be taken out from the housing 11, only the housing cover 112 is required to be pulled out in a direction away from the housing 111, and after the first clamping portion 112b and the second clamping portion 111a are separated, the housing cover 112 is also separated from the housing 111, and at this time, the machine body 12 can be taken out from the housing 111.

In the case 11 shown in fig. 4, 5, and 12, when the cover 112 and the case 111 are connected, the first engagement portion 112b and the second engagement portion 111a are hidden inside the case 11, and the first engagement portion 112b and the second engagement portion 111a are not visible from the exterior, so that the exterior of the case 121 can be more beautiful.

It should be noted that, the manner of locking the cover 112 and the housing 111 is not limited to providing the first locking portion 112b on the first connecting portion 112a and providing the second locking portion 111a on the inner wall of the housing 111, and in other embodiments, other locking manners may be used for locking the cover 112 and the housing 111, so long as the cover 112 and the housing 111 can be detachably connected by locking.

For example, the cover 112 may be detachably connected to the housing 111 by sleeving, for example, referring to fig. 6 and 13, the cover 112 may also include a second connecting portion 112c having a relief opening 11a, where the second connecting portion 112c extends into the housing 111 and is sleeved with the housing 111.

That is, after the second connecting portion 112c extends into the housing 111, a certain micro deformation is generated between the second connecting portion 112c and the housing 111, and under the effect of the micro deformation, the second connecting portion 112c is attached to the housing 111, so that the housing cover 112 and the housing 111 are connected together, and when the housing cover 112 needs to be separated from the housing 111, only the housing cover 112 needs to be pulled away from the housing 111, so that the second connecting portion 112c is separated from the housing 111.

In order to improve the reliability of the coupling between the cover 112 and the housing 111, the cover 112 may be made of a material that is easily deformed by micro-deformation, such as silica gel.

It should be noted that, the cover 112 and the housing 111 are not limited to being sleeved with the housing 111 through the second connection portion 112c of the cover 112, and in other embodiments, other sleeving manners may be adopted for the cover 112 and the housing 111, and only the cover 112 and the housing 111 can be detachably connected through sleeving.

The cover 112 and the housing 111 can also be detachably connected by means of a magnetic attraction fit, for example. For example, referring to fig. 7 and 14, the cover 112 may include a third connection portion 112d having an avoidance port 11a, the housing 11 includes a first magnetic member 113 disposed on the third connection portion 112d and a second magnetic member 114 disposed on an inner wall of the housing 111, a portion of the third connection portion 112d where the first magnetic member 113 is disposed extends into the housing 111, and the first magnetic member 113 and the second magnetic member 114 are magnetically engaged.

One of the first magnetic attraction member 113 and the second magnetic attraction member 114 may be a magnet, the other may be a metal member capable of magnetically attracting with the magnet, or both the first magnetic attraction member 113 and the second magnetic attraction member 114 may be magnets.

The third connecting portion 112d of the cover 112 is inserted into the housing 111, and the first magnetic attraction member 113 and the second magnetic attraction member 114 are magnetically attracted and matched, so that the cover 112 and the housing 111 can be connected together, and when the cover 112 needs to be separated from the housing 111, the cover 112 needs to be pulled away from the housing 111, so that the first magnetic attraction member 113 and the second magnetic attraction member 114 need to be separated.

It should be noted that, the magnetic coupling manner of the cover 112 and the housing 111 is not limited to the arrangement of the first magnetic member 113 on the third connecting portion 112d, and the arrangement of the second magnetic member 114 on the inner wall of the housing 111, and in other embodiments, other magnetic coupling manners may be adopted for the cover 112 and the housing 111, so long as the cover 112 and the housing 111 can be detachably connected through magnetic coupling.

In an embodiment, the casing 121 may be detachably connected to the housing 11, for example, the casing 121 and the housing 11 may be detachably connected by a clamping, sleeving, or magnetic attraction manner.

When the casing 121 and the housing 11 are detachably connected, the housing 11 may have the housing 111 and the cover 112, or only the housing 111 may be provided, and the cover 112 may be omitted, so that the opening corresponding to the housing 111 is the escape opening 11a, and the body 12 may be inserted into the housing 111 from the opening of the housing 111, and the casing 121 and the housing 111 may be detachably connected.
