As used herein, the term "internal heater" refers to a heater that is positioned at least partially within an aerosol-generating article when the aerosol-generating system comprising the aerosol-generating article is assembled. As used herein, the term "air heater" refers to a heater for heating air in an air intake passage through which air enters an aerosol-generating article, the air heater heating air flowing through the air intake passage to high temperature air which then enters the aerosol-generating article, exchanging heat with the aerosol-generating article, effecting heating and baking of the aerosol-generating article. The heating assembly has one or more heating assemblies capable of reaching a temperature between about 200 ℃ and 440 ℃ to enable aerosol generation of the aerosol-generating article.

When the aerosol-forming substrate is a liquid aerosol-forming substrate, the heating assembly comprises a liquid guide for absorbing and transporting the liquid aerosol-forming substrate and an atomizing member for atomizing at least part of the liquid aerosol-forming substrate on the liquid guide. The liquid guide may be made of a material having capillary channels or pores, such as a rigid or rigid capillary structure of cellocotton, porous ceramic body, glass-fiber rope, porous glass-ceramic, porous glass, etc. The liquid guide is in fluid communication with the cartridge storing the liquid aerosol-forming substrate to draw the liquid aerosol-forming substrate delivered from the cartridge and deliver the liquid aerosol-forming substrate to the vicinity of the atomizing member. In one embodiment, the liquid guide includes an atomizing surface and a liquid suction surface, the liquid suction surface being in fluid communication with the cartridge; the atomizing piece is a heater, and the heater is arranged on the atomizing surface and is used for heating at least part of liquid aerosol forming substrate absorbed by the liquid guide piece to generate aerosol when the power is on, and the aerosol is released after escaping from the atomizing surface.

Referring to fig. 1, the aerosol-generating device may comprise a battery assembly 3 for supplying electrical power to the aerosol-generating assembly 2. The battery assembly 3 may include any suitable battery 31. In one embodiment, the battery 31 is a lithium ion battery.

The battery assembly 3 may include a circuit board 32 and one or more control circuits provided on the circuit board 32, which may control the output of the battery 31, for example, to cause the battery 31 to output alternating current or direct current, or the like, or to cause the battery 31 to output current or voltage, or the like, in the form of pulses, for example.

The control circuit may have one or more controllers thereon. The controller may control the overall operation of the aerosol-generating device. In detail, the controller controls not only the operation of the battery and the heating assembly, but also the operation of other elements in the aerosol-generating device. Furthermore, the controller may determine whether the aerosol-generating device is operable by checking the status of the elements of the aerosol-generating device. The controller includes at least one processor. The processor may comprise an array of logic gates, or may comprise a combination of a general purpose microprocessor and a memory storing programs executable in the microprocessor. Furthermore, those skilled in the art will appreciate that the controller may include another type of hardware.

Referring to fig. 1, the battery assembly 3 further includes a first electrode connector 33 and a second electrode connector 34, the battery 31 is located between the first electrode connector 33 and the second electrode connector 34, one of the positive electrode and the negative electrode of the battery 31 is used for electrically abutting the first electrode connector 33, the other is used for electrically abutting the second electrode connector 34, the battery 31 outputs power to the control circuit through electrically abutting the first electrode connector 33 and the second electrode connector 34, and further outputs power to the aerosol generating assembly 2, the aerosol generating assembly 2 generates aerosol from the aerosol generating product 1 based on the power output by the battery 31, and the battery 31 is detachably connected with the first electrode connector 33 and the second electrode connector 34, so that the battery 31 can be replaced.

Fig. 1 provides a schematic view of the first electrode connector 33 and the second electrode connector 34, the first electrode connector 33 and the second electrode connector 34 including an elastic member 35 for abutting against an electrode of the battery 31, for example, the elastic member 35 is a metal elastic sheet or a metal spring or the like, so that the abutment between the battery 31 and the first electrode connector 33 and the second electrode connector 34 is elastic abutment, and the battery 31 can be stably held between the first electrode connector 33 and the second electrode connector 34 by elastic abutment with the first electrode connector 33 and the second electrode connector 34, and stably electrically connected with the first electrode connector 33 and the second electrode connector 34.

Referring to fig. 1 and 2, the aerosol generating device further comprises a battery holder 4. The battery holder 4 has a receiving cavity 41 therein, the receiving cavity 41 being at least capable of receiving a battery 31 in the battery assembly 3, and in some embodiments, referring to fig. 4, the battery holder 4, the first electrode connector 33 and the second electrode connector 34 together define a receiving cavity 41 accommodating the battery 31. In some embodiments, referring to fig. 2 and 3, the receiving cavity 41 is defined solely by the battery holder 4, and the first electrode connector 33, the battery 31, and the second electrode connector 34 may all be received in the receiving cavity 41. The battery holder 4 has a window 42 through which the battery 31 can be inserted into the receiving chamber 41 or removed from the receiving chamber through the window 42, so that the battery 31 can be replaced.

The aerosol generating device further comprises a housing 5, at least part of the housing 5 being located outside the battery holder 4, the bottom of the housing 5 being provided with an end cap 53, at least the end cap 53 of the housing 5 being movable relative to the battery holder 4, and the window 42 being opened by removing at least the end cap 53 of the housing 5, i.e. the end cap 53 has the effect of closing the window 42. It should be noted that, the closed window and window closure described herein are with respect to a window that is open or open, and refer to a window that is not permeable to a battery, and that does not exclude the window from allowing air to pass through when the closed window and window are closed.

In an embodiment, referring to fig. 2 and 3, the window 42 of the battery holder 4 is provided at the bottom end, the window 42 being provided opposite the aerosol-generating assembly 2, i.e. the window 42 is provided near or at the bottom of the aerosol-generating device, so that the battery 31 is replaced without having to disassemble or remove the aerosol-generating assembly 2. Based on this, the direction of taking out and loading the battery 31 is parallel to the longitudinal direction of the battery 31. The end cap 53 is attached to the rear of the battery holder 4 and is removable with respect to the battery holder 4, and the window 42 is open after the end cap 53 is removed from the battery holder 4.

In the embodiment shown in fig. 2 and 3, the first electrode connection member 33 is provided at the window 42, or the first electrode connection member 33 is provided near the window 42, and if the first electrode connection member 33 is held in this position, the first electrode connection member 33 blocks the removal of the battery 31 from the receiving chamber 41. The end cap 53 on the housing 5, by mating with the battery holder 4, can hold the first electrode connector 33 in abutment with the battery 31.

Specifically, the first electrode connector 33 may be fixed to the end cap 53 such that the first electrode connector 33 may be removably disposed with the end cap 53 with respect to the battery holder 4 such that when the end cap 53 is separated from the battery holder 4 to expose the window 42, or when the end cap 53 is moved with respect to the battery holder 4 to expose the window 42, the first electrode connector 33 is separated from the window 42 and separated from the battery 31, such that an end of the battery 31 abutting the first electrode connector 33 is exposed, and during removal of the battery 31, an end of the battery 31 abutting the first electrode connector 33 is first removed from the receiving cavity 41 and removed through the window 42. Conversely, when the battery 31 is loaded into the receiving chamber 41, the end of the battery 31 abutting the first electrode connector 33 finally enters the receiving chamber 41. And when the end cover 53 is separated from the battery holder 4 to expose the window 42, or when the end cover 53 is moved relative to the battery holder 4 to expose the window 42, the abutment force of the first electrode link 33 against the battery 31 disappears, so that the clamping force of the first electrode link 33 and the second electrode link 34 against the battery 31 disappears, thereby making it possible to more easily take out the battery 31 from the receiving chamber 41 and to load the battery 31 into the receiving chamber 41.

Further, the case 5 may further include a bottom cover 52 detachable from the battery holder 4, the bottom cover being located at the outer periphery of the end cover 52, at least part of the end cover 53 may be hidden by shielding when the bottom cover 52 is coupled to the battery holder 4, the bottom cover 52 may form the bottom of the aerosol generating device, and the bottom cover 52 may have an effect of beautifying the external appearance of the aerosol generating device.

Wherein the end cap 53 may also be made to close the window 42 by the engagement of the bottom cap 52 with the battery holder 4. In an example, the bottom cover 52 is separable from the end cover 53, the end cover 53 is exposed when the bottom cover 52 is detached from the battery holder 4, and the bottom cover 52 abuts against the end cover when the bottom cover 52 is attached to the battery holder 4, such that the first electrode connector 33 fixed to the end cover 53 abuts against one end of the battery while the other end of the battery 31 abuts against the second electrode connector 34, thereby electrically connecting the first electrode connector 33 and the second electrode connector 34 with the battery 31.

Referring to fig. 1 and 2, the battery holder may include a hollow tube, the battery 31, the first electrode connecting member 33 and the second electrode connecting member 34 may be accommodated in the hollow tube, the window 42 is located at the tail of the hollow tube, and the bottom cover 52 is detachably connected to the tail end of the hollow tube. In one example, the end cap 53 is in clearance fit with the inner wall of the hollow tube, so that the end cap 53 can automatically withdraw from the hollow tube under the action of gravity of the end cap and the first electrode connector 33, and separate from the window 42, thereby exposing one end of the battery 31 connected with the first electrode connector 33, and the battery 31 can also be in clearance fit with the inner wall of the hollow tube, so that after the first electrode connector 33 separates from the window 42, the battery 31 can also automatically withdraw from the hollow tube under the action of gravity of the end cap, separate from the receiving cavity 41, thereby realizing the removal of the battery 31; conversely, the user can easily load a new battery 31 into the receiving chamber 41, and when the window 42 is turned upside down, the battery 31 automatically enters the receiving chamber 41 along the length direction of the hollow tube and abuts the second electrode connector 34 under the action of the self-gravity. In one example, the inner wall of the hollow tube defining the receiving cavity 42 is smooth to facilitate sliding of the battery 31 along the inner wall of the hollow tube to facilitate loading and unloading of the battery 31.

Specifically, referring to fig. 1 and 2, the inner wall of the hollow tube is substantially circular, the outer periphery of the end cap 53 is also substantially circular, and the diameter of the inner wall of the hollow tube is larger than the diameter of the outer periphery of the end cap 53, so that the end cap is in clearance fit with the inner wall of the hollow tube 53. The diameter of the inner wall of the hollow tube is larger than the diameter of the battery 31 so that the battery 31 is in clearance fit with the inner wall of the hollow tube.

In the embodiment shown in fig. 1-3, only one battery 31 can be accommodated in the receiving cavity 42, but this is optional and not necessary, and in other embodiments, not shown, multiple batteries can be accommodated in the receiving cavity, and the multiple batteries can be arranged in a line and connected in sequence, i.e. connected in series with each other; for example, a first battery cell may be in abutment with the second electrode connection, a trailing battery cell may be in abutment with the first electrode connection, and the remaining battery cells may be located between the first battery cell and the trailing battery cell.

In the embodiment shown in fig. 1-3, at least a partial outer side of the battery holder 4 constitutes at least a partial outer side wall of the aerosol-generating device. In particular, at least the outer side surface of the hollow tube on the battery support 4 forms at least a partial outer side wall of the aerosol generating device, so that at least a shell is not required to be arranged on the periphery of the hollow tube to form the outer side wall of the aerosol generating device, which is beneficial to reducing the volume of the aerosol generating device or increasing the volume of the receiving cavity 42 for accommodating the batteries 31, so that the battery support 4 can accommodate the batteries 31 with larger electric quantity or accommodate more batteries 31, and the duration of the aerosol generating device is beneficial to prolonging.

In the embodiment shown in fig. 1-3, the bottom cap 52 includes a threaded portion having internal threads on the inner wall of the hollow tube tail that extend into the hollow tube tail and are connected to the hollow tube by a threaded engagement such that the bottom cap 52 is removably connected directly to the hollow tube. In the embodiment shown in fig. 1-3, the hollow tube forms at least a partial outer side wall of the aerosol-generating device, and the partial insertion of the hollow tube into the bottom cap relative to the threaded connection of the hollow tube to the bottom cap facilitates better integrity of the outer side wall of the aerosol-generating device by partially extending the bottom cap 52 into the hollow tube such that only the bottom portion of the bottom cap 52 is exposed. It should be noted that, when the hollow tube forms at least a part of the outer side wall of the aerosol generating device, the threaded connection between the hollow tube and the bottom cover 52 is optional, but not necessarily, and the hollow tube and the bottom cover 52 may be detachably connected by magnetic attraction, fastening, or the like.

In one embodiment, the first electrode connection member 33 is movably disposed with respect to the battery holder 4 regardless of whether the first electrode connection member 33 is fixed to the end cap 53 or is independently disposed with respect to the end cap 53. Of course, the possibility of the second electrode connection 34 being arranged movably relative to the battery support 4 is not excluded in other embodiments.

In one embodiment, whether the first electrode connector 33 is fixed to the end cap 53 or is provided separately from the end cap 53, the battery assembly 4 is configured such that the interval between the first electrode connector 33 and the second electrode connector 34 is variable, the battery 31 is conveniently loaded and unloaded by increasing the interval between the first electrode connector 33 and the second electrode connector 34, the first electrode connector 33 and the second electrode connector 34 are clamped to the battery 31 by reducing the interval between the first electrode connector 33 and the second electrode connector 34, and the battery 31 is held in the receiving cavity 42 while the first electrode connector 33 and the second electrode connector 34 are electrically connected to opposite ends of the battery 31, respectively.

In order to prevent the first electrode link 33 from being lost when the first electrode link 33 is separated from the battery 31, the aerosol generating device further includes a link 36 having one end fixed in the battery holder 4 and the other end connected to the first electrode link 33, so that the first electrode link 33 is still connected to the battery holder 4 through the link 36 when the first electrode link 33 is removed from the battery holder 4, and the position of the first electrode link 33 is limited within a preset range under the connection of the link 36. If the flexible connection unit 36 is a non-electrical connection unit, it mainly plays a role in preventing the first electrode connection unit 33 from being lost, and when the first electrode connection unit 33 is fixed on the end cover 53, one end of the connection unit 36 is fixed in the battery holder 4, and the other end of the connection unit is connected to the end cover, so that the end cover can be prevented from being lost.

The connection member 36 may be a flexible connection member such that when the first electrode connection member 33 closes the window 42, the connection member 36 may be received in the receiving chamber 41 by bending or bending the connection member 36, and when the first electrode connection member 33 is moved away so that the window 42 is opened, the bent or bent connection member 36 may be unfolded or partially unfolded such that the first electrode connection member 33 caught by the connection member 36 may be located outside the battery holder 4.

In the embodiment shown in fig. 2 and 3, the flexible connection member 36 is an electrical connection member, which may be, for example, a wire or a flexible circuit board, etc., and one end of the flexible connection member 36 is electrically connected to the aerosol-generating assembly 3 fixed to the battery holder 4 or to the circuit board 32 having the control circuit fixed to the battery holder 4, so that one end of the flexible connection member 36 is fixed in the battery holder 4 and the other end is electrically connected to the first electrode connection member 33, and the first electrode connection member 33 outputs electric power to the circuit board 32 or to the aerosol-generating assembly 2 through the flexible connection member 36 electrically connected thereto. When the flexible connector 36 is an electrical connector, the first electrode connector 33 can be electrically connected to the circuit board 32 or the aerosol-generating assembly 2 while abutting the battery 31, which helps to simplify the steps of removing and inserting the first electrode connector 33, which helps to replace the battery 31.

In one embodiment, the second electrode connector 34 is inseparably connected to the battery holder 4 such that when the window 42 is facing downward and when the window 42 is exposed, the second electrode connector 34 does not lose connection with the battery holder 4, helping to prevent the second electrode connector 34 from losing.

Further, the second electrode connection member 34 may be fixedly connected to the battery holder 4 and held in the battery holder 4 such that the second electrode connection member 34 cannot move relative to the battery holder 4.

Alternatively, the second electrode connection member is electrically connected to the circuit board or to the aerosol-generating assembly by a flexible connection member of sufficient length so that the second electrode connection member can move within a certain range relative to the battery support 4.

It should be noted that the connection member is optional, but not necessary, in other embodiments, the connection member may be a telescopic member, and when the window is closed, the connection member is contracted so as to be received in the receiving chamber, and when the window is closed, the connection member is elongated so that the first electrode connection member/second electrode connection member connected thereto can be moved outside the battery holder; on this basis, the telescopic member may have elasticity so that the first electrode connector and/or the second electrode connector can be ejected out of the battery holder after the bottom cover or the end cover is removed, or at least partially eject the battery out of the battery holder while the first electrode connector is ejected.

In an embodiment, referring to fig. 4 and 5, the window 42 of the battery holder 4 is provided on the side wall, the window 42 is located below the aerosol-generating assembly 2, based on which the direction of taking out and loading the battery 31 is perpendicular to the length direction of the battery 31, and there is no need to disassemble or remove the aerosol-generating assembly 2 when replacing the battery 31. In this embodiment, the interval between the first electrode connecting member 33 and the second electrode connecting member 34 may be fixed, the window 42 is located between the first electrode connecting member 33 and the second electrode connecting member 34, the aerosol generating device includes the housing 5, the housing 5 is detachably connected to the battery holder 4 or the housing 5 is slidably connected to the battery holder 4 or rotatably connected, the window 42 is exposed by changing the position of the housing 5 or disengaging the housing 5 from the battery holder 4, and the window 42 is opened when the window 42 is completely exposed, so that the battery 31 can pass through the window 42; by changing the position of the housing 5 in the opposite direction or by attaching the housing 5 to the battery holder 4, the window 42 is blocked, and the blocked window 42 is closed, resulting in that the battery 31 cannot pass through the window 42.

In this embodiment, the housing 5 may have a tubular portion 51, the tubular portion 51 being disposed around the periphery of the battery holder 4, the window 42 being located inside the tubular portion 51 when the housing 5 is in the first position, the window 42 being closed, the window 42 being exposed outside the tubular portion 51 when the housing 5 is in the second position, the window 42 being open.
