The atomization temperature required for the liquid medium varies depending on the composition of the liquid medium to be atomized, and the atomization method of the aerosol-generating device is different in order to match the preferable atomization effect. For example, when the liquid matrix contains pharmaceutically active functional components, the required atomization temperature is generally low, and the aerosol-generating device generally uses an ultrasonic atomizer; when the liquid matrix contains nicotine products, the required atomization temperature is relatively high, and an aerosol generating device generally adopts an atomization mode such as a resistance heater or an electromagnetic heater.
Fig. 1 and 2 show one embodiment of an aerosol-generating device, which mainly comprises an atomizing device 100 and a power supply assembly 200, the power supply assembly 200 being arranged to provide an electrical power supply for the atomizing device. The power supply assembly 200 includes a battery case 20, a battery 21 accommodated in an inner cavity of the battery case 20, and a control board 24. The power supply assembly 200 is used as a main body of the aerosol-generating device, and the battery pack 20 is mainly held by a user during the use of the aerosol-generating device, so that in order to improve the holding feel of the battery pack 20, the battery pack 20 preferably adopts a combination of hard plastic injection molding and soft plastic injection molding to form a double-layer shell, wherein the outermost layer is a soft plastic shell, so that the softness of the battery pack 20 when touching is improved.

Sealing elements, such as annular sealing rings, are provided at the mounting interfaces of the various components on the power supply assembly 200 to promote overall sealing performance of the aerosol-generating device.
The atomizing device 100 includes a housing and an atomizing assembly 30 disposed within the housing. In one example provided by the application, the liquid matrix atomized by the atomizing device 100 contains active functional components of medicines, the atomizing assembly 30 is in an ultrasonic atomizer structure, the atomizing assembly 30 comprises a piezoelectric ceramic plate, a metal atomizing plate with a micropore structure, a silica gel sleeve and a plastic fixing shell 31, the piezoelectric ceramic plate and the metal atomizing plate are fixed in an inner cavity of the silica gel sleeve, the silica gel sleeve is further contained in the plastic fixing shell 31, the atomizing plate is configured to have a mesh structure and can vibrate, liquid drops of the liquid matrix are scattered through high-frequency vibration to form micron-sized aerosol, and the piezoelectric ceramic plate is connected with the power supply assembly 200 through an elastic electrode. The atomizing device 100 is further provided with a suction nozzle (not shown) configured as a nozzle-type nozzle having a mesh structure, and the aerosol is sucked by a user after being filtered through the mesh of the suction nozzle.
A portion of the housing of the atomizing device is configured as a chamber for storing a liquid matrix, with a fluid passage disposed between the chamber for storing liquid and the atomizing chamber through which the liquid matrix is provided to the atomizing assembly 30. In one example provided by the present application, referring to fig. 3 and 4, the housing of the atomizing device comprises two parts, namely a first housing 51 and a second housing 52, wherein the inner cavity of the first housing 51 defines a first chamber 511, the inner cavity of the second housing 52 defines a second chamber 521, the interior of the first chamber 511 is used for storing the liquid matrix, the interior of the second chamber 521 is used for accommodating the atomizing assembly 30, and the central axis of the first chamber 511 is disposed at an angle to the central axis of the second chamber 521. Further, in one embodiment provided by the present application, the atomizing assembly 30 is removably received within the second chamber 521, facilitating the ability of a user to remove the atomizing assembly 30 for cleaning or to replace the atomizing assembly 30 with a new one. In a specific implementation, the atomization assembly 30 is rotatably buckled on the inner wall of the second housing 52, two annular grooves with pits are arranged on the outer plastic fixing housing 31 of the atomization assembly 30, two annular grooves with bumps are arranged on the inner wall of the second housing 52, the atomization assembly 30 can rotate relative to the second housing 52, the atomization assembly 30 is placed into the second chamber 521 through the opening at the end part of the second housing 52, the atomization assembly 30 is rotated until the pits and the bumps are mutually clamped, and the atomization assembly 30 is clamped in the second chamber 521; the concave points of the counter-rotating atomizing assembly 30 are offset from the convex points, and the atomizing assembly 30 can be rotated out of the open end of the second housing 52. Correspondingly, a suction nozzle is detachably connected to the open end of the second housing 52.
The reservoir of the prior art aerosolizing device 100 is typically configured to be closed and difficult for a user to add a liquid matrix to its interior. When the aerosol-generating device is used as the administration atomizing device 100, the aerosol-generating device is expected to be capable of quantitatively replenishing the liquid matrix so that the user can use the aerosol-generating device in a metered amount. In one embodiment of the present application, and as shown with reference to fig. 4-10, the liquid matrix atomized by the atomizing device 100 is stored in a separate reservoir 10, the reservoir 10 being configured to be replaceable, and the user can replenish the liquid matrix by replacing the liquid matrix within the reservoir 10 when the liquid matrix is consumed. The reservoir 10 is configured in a closed state to facilitate easy portability by a user and to facilitate safety of liquid storage. An open first chamber 511 is provided on the aerosol-generating device through which the reservoir 10 may be removably received inside the first chamber 511. The first chamber 511 is configured to stably house a reservoir.
The reservoir 10 is provided as a consumable part of an aerosol-generating device, a single reservoir 10 may be configured in the form of a capsule, a single reservoir 10 or a combination of multiple reservoirs 10 may be sold separately, and the shape of the reservoir 10 may be stylized according to the individual vending requirements. In some examples, the housing of the reservoir 10 is configured to be symmetrically disposed along its length and width such that the reservoir 10 can be inserted into the interior of the first chamber 511 at multiple angles. Such as a housing of the reservoir 10 having one of a circular, oval, racetrack ring, square, and rectangular cross-section.
As will be described in detail below with reference to fig. 5 to 7, the reservoir 10 includes a housing 11, the housing 11 including a side wall and a top wall enclosing a reservoir chamber 110 for storing a liquid matrix, the housing 11 being provided with no bottom wall, and an opening at a bottom end of the housing 11 providing an outlet for outflow of the liquid matrix, the opening of the reservoir 10 being closed by a shutter before use. When the reservoir 10 is placed in use in the first chamber 511 of an aerosol-generating device, the opening is opened to enable the liquid matrix to flow out. The housing 11 may be made of a transparent material or a transparent window may be provided in the housing 11 so that a user can view the liquid matrix inside the reservoir 10 through the transparent housing 11 or the transparent window.
Since the reservoir 110 is configured as a relatively closed space, when the reservoir 10 is placed in the first chamber 511 of the interior of the aerosol-generating device for use, as the liquid matrix inside the reservoir 110 is consumed, the remaining space of the reservoir 110 gradually forms a negative pressure, and the outlet of the reservoir 10 is in communication with the atmosphere, so that the liquid matrix is difficult to flow out from the liquid outlet on the reservoir 10 due to the negative pressure, thereby affecting the normal use of the remaining liquid matrix. In order to suppress the formation of negative pressure, another opening communicating with the atmosphere is provided in the housing 11 of the reservoir 10.
Specifically, referring to fig. 6 and 7, a first opening 111 and a second opening 112 are provided on the housing 11 of the reservoir 10, wherein the first opening 111 is configured to be capable of communicating with the outside atmosphere, and the second opening 112 provides an outlet for outflow of the liquid matrix. Meanwhile, a first shutter 12 is provided on the first opening 111, the first opening 111 is sealed by the first shutter 12 before the reservoir 10 is not used, a second shutter 13 is provided on the second opening 112, and the second opening 112 is sealed by the second shutter 13 before the reservoir 10 is not used, so that the entire reservoir 10 is configured as a sealed cavity before it is not used. Since the first opening 111 is only provided as an inlet for providing gas into the liquid storage chamber 110, in order to prevent leakage of the liquid matrix from the first opening 111, the area of the first opening 111 is set to be small enough, and the second opening 112 is provided as an outlet for the liquid matrix, the area of the second opening 112 is large enough to facilitate smooth outflow of the liquid matrix from the second opening 112, and thus the area of the first opening 111 is much smaller than the area of the second opening 112. For example, referring to fig. 7, the first opening 111 is only a small opening at the top end of the housing 11, and the second opening 112 is the entire opening at the bottom end of the housing 11. The area of the first opening 111 is approximately 1/5, 1/10 or even smaller than the area of the second opening 112. During use of the reservoir 10, the first opening 111 needs to be in communication with the outside air, and therefore the first opening 111 is preferably provided on the top wall of the housing 11. It will be appreciated that when the first opening 111 is provided in the top wall of the housing 11 of the reservoir 10, it is only necessary that the top wall portion of the housing 11 of the reservoir 10 be exposed to the exterior of the aerosol-generating device, and that external air flow is able to enter the interior of the reservoir chamber 110 via the first opening 111. While when the first opening 111 is provided on the side wall of the housing 11 of the reservoir 10, at least part of the side wall of the housing 11 of the reservoir 10 needs to be exposed to the outside of the aerosol-generating device so that an external air flow can communicate with the first opening 111, the reservoir 10 needs to be placed sideways inside the aerosol-generating device or the reservoir 10 needs to be exposed to the outside of the aerosol-generating device over a larger area, which is detrimental to a stable placement of the reservoir 10 inside the aerosol-generating device and also to an airtight connection between the reservoir 10 and the main body part of the aerosol-generating device.
Further, since the first opening 111 providing ventilation is provided in the liquid reservoir 10, no additional ventilation channel is required in the aerosol-generating device, so that the leak-proof performance and the airtight performance of the aerosol-generating device are better, which is beneficial to further improving the service life of the aerosol-generating device. And the first opening 111 is opened again on a new reservoir 10 every time the user replaces the reservoir 10, the ventilation structure is more stable, and ventilation can be effectively performed.
In order to facilitate the user to open the first opening 111, the first shielding member 12 is configured to be easily destructively disposed on the first opening 111, the first shielding member 12 may be made of a film material, which may be aluminum foil or tin foil, to form a sealing film, and an external force is applied to a certain point of the first shielding member 12, so that the first shielding member 12 is destructed; or the first shielding member 12 is made of a flexible silica gel material, specifically, a weakened portion may be further provided on the first shielding member 12, and an external force is applied to the weakened portion, so that the weakened portion of the first shielding member 12 is broken, thereby opening at least part of the first opening 111. It should be noted that, if the first shielding member 12 is a silica gel plug made of a flexible silica gel material, the first opening 111 of the reservoir 10 may occupy a larger area at the top end of the housing 11, for example, the housing 11 of the reservoir 10 is not provided with a top wall, but is directly connected with the silica gel plug in a sealing manner on the top end of the housing 11, and when the first opening 111 needs to be opened, only the weakened portion on the silica gel plug needs to be broken.
In one example provided by the present application, the first shutter 12 is configured as a sealing film or a silicone plug with weakened locations, the first shutter 12 requiring a force to be applied by means of a piercing member with a sharp portion to be ruptured to open the first opening 111. A cover 15 is provided at one end of the housing 11, a first piercing member 16 is provided on an inner surface of the cover 15, the first piercing member 16 extending from a top end of the cover 15 in a direction toward the first shielding member 12, the cover 15 being configured to be movable relative to the housing 11 from a first position to a different second position. Wherein when the cover 15 is in the first position, the top wall of the cover 15 is at a sufficient distance from the upper end of the housing 11 such that the first lancet 16 on the cover 15 is located at the upper end of the first shield 12, and the reservoir 110 is configured as a sealed cavity, as shown in fig. 5. When the cover 15 is in the second position, the first piercing member 16 on the cover 15 pierces the first shutter 12 to open the first opening 111, as shown in fig. 8. When the cover 15 is in the first position, the first piercing member 16 is accommodated in the closed space defined by the cover 15 and the top wall of the housing 11, so that the user cannot contact with the first piercing member 16, and the risk of the user contacting the first piercing member 16 to scratch the user is prevented. One end of the first piercing member 16 is provided on the inner wall of the cap 15, and the second end of the first piercing member 16 is provided as a tip, and the first piercing member 16 mainly uses its tip to pierce the first shutter 12. During the movement of the cover 15 from the first position to the second position, the tip of the first piercing member 16 gradually contacts the first shielding member 12 and pierces the first shielding member 12, and when the cover 15 is in the second position, the top surface of the inner wall of the cover 15 contacts the top wall of the housing 11, and at least part of the first piercing member 16 protrudes into the interior of the liquid storage chamber 110.
In other examples, the cover 15 is fixedly connected to one end of the housing 11, and at least part of the wall of the cover 15 is made of an elastic material to form an elastic wall, and the elastic wall of the cover 15 is elastically deformed when being subjected to an external pressing force. The first piercing member 16 is provided on the inner surface of the elastic wall of the cover 15 and extends longitudinally from the tip of the elastic wall of the cover 15 toward the first shutter 12, applying a downward pressing force to the elastic wall of the cover 15, the elastic wall of the cover 15 being elastically deformed downward in the longitudinal direction thereof, and the first piercing member 16 being simultaneously moved downward such that the tip of the first piercing member 16 pierces the first shutter 12.
In a further example provided by the present application, the first shutter 12 is configured as a sealing film with a tear port, and the first shutter 12 is removed from the first opening 111 by applying an external force to the tear port of the first shutter 12. The first opening 111 and the first shutter 12 are hidden in order not to affect the overall aesthetic appearance of the reservoir 10 or to prevent a user from adding liquid matrix to the interior of the reservoir 110 through the first opening 111. Specifically, a cover 15 is connected to one end of the housing 11, and the first opening 111 and the first shutter 12 are blocked by the cover 15, so that the first shutter 12 and the first opening 111 are not visible from the outer surface of the reservoir 10. The cover 15 is removably attached to one end of the housing 11, and the first shutter 12 covers 15 the first opening 111 before being unused, and the cover 15 is attached to one end of the housing 11. Prior to use, the cover 15 is removed from one end of the housing 11, exposing the first shutter 12, and the first shutter 12 is removed from the first opening 111 using a tear in the first shutter 12. After the first opening 111 is opened, the cover 15 is attached to one end of the housing 11, and a vent hole 161 is further provided in the cover 15, so that the atmosphere enters the inside of the liquid storage chamber 110 through the vent hole 161 and the first opening 111. Wherein the cap 15 and the housing 11 may be configured as a threaded connection or a snap-fit connection.
A vent hole 161 is provided in the cover 15 through the first piercing member 16, the vent hole 161 being for guiding an external air flow into the liquid storage chamber 110. Referring to fig. 7 to 10, the vent hole 161 is configured in a form of being expanded toward one end of the reservoir 110 in its longitudinal direction, i.e., the vent hole 161 is provided at one end of the outer surface of the cap 15 with a smaller aperture and provided at one end of the tip of the first piercing member 16 with a larger aperture, in such a manner that the external air flow can be effectively introduced into the interior of the reservoir 110, while the end aperture of the vent hole 161 is sufficiently small that it is difficult for the user to observe the presence of the vent hole 161 without applying sufficient attention, thereby preventing the user from replenishing the liquid matrix into the interior of the reservoir 110 through the vent hole 161. When the cover 15 is in the second position, the first piercing member 16 passes through the first opening 111 and a portion of the first piercing member 16 extends into the interior of the reservoir 110, and an external air flow enters the interior of the reservoir 110 through the vent hole 161.
In some embodiments, a first stop structure 141 and a second stop structure 142 are provided on the cover 15 or the housing 11, and a stop structure 143 is provided on the housing 11 or the cover 15, the first stop structure 141 and the stop structure 143 cooperating to enable the cover 15 to be stably held in the first position when the cover 15 is in the first position, and the second stop structure 142 and the stop structure 143 cooperating to enable the cover 15 to be stably held in the second position when the cover 15 is in the second position. In one example, the first stop structure 141 is two first notches symmetrically disposed on the inner walls of the two sides of the cover 15, and the second stop structure 142 is two second notches symmetrically disposed on the inner walls of the two sides of the cover 15, wherein a distance between the first notches and the second notches defines a travel of the cover 15 between the first position and the second position. The stop structure 143 is two buckles symmetrically arranged on the outer walls of the two sides of the shell 11, and the buckles can be clamped with the first notch and the second notch. When the reservoir 10 is required to be used, a pressing force is applied to the top end surface of the cap 15 of the reservoir 10, and the cap 15 can be moved from the first position to the second position. A flange is provided on the outer wall of the housing 11, and when the cover 15 is moved to the second position, the inner wall surface of the cover 15 abuts against the top end surface of the housing 11, and the lower end surface of the cover 15 abuts against the flange on the housing 11.
In some embodiments, to prevent accidental puncturing of the first opening 111 prior to use of the reservoir 10, a blocking ring is provided on the outer wall of the housing 11, the cap 15 being in the first position prior to use of the reservoir 10, a space being left between the lower end surface of the cap 15 and the flange of the housing 11, the blocking ring being provided in the spaced region, the blocking ring being operable to block movement of the cap 15 on the reservoir 10 under accidental conditions, thereby enabling the cap 15 to be stably held in the first position. Further provided with a tear on the blocking ring, which is removed from the reservoir 10 when the reservoir 10 is to be used, enables the cover 15 to be moved unimpeded from the first position to the second position.
In other examples, instead of the snap connection, a screw connection may be provided between the cover 15 and the housing 11, and an internal screw thread may be provided on the inner wall of the cover 15 and an external screw thread may be provided on the housing 11. A flange is provided on the outer wall of the housing 11, the lower end face of the cover 15 being spaced from the flange when the cover 15 is in the first position, and a blocking ring is provided on the space. The blocking ring enables the cap 15 to be stably maintained in the first position, and when the reservoir 10 is required to be used, the blocking ring is removed and the cap 15 is rotated until the lower end surface of the cap 15 abuts the flange on the housing 11, the cap 15 being in the second position. Correspondingly, the first piercing member 16 on the cap 15 moves down with the rotation of the cap 15 and gradually comes into contact with the first shielding structure and breaks the first shielding member 12, thereby opening the first opening 111.
In some embodiments, the liquid reservoir 10 is further provided with a sealing element 17, the sealing element 17 protrudes from the outer surface of the housing 11 of the liquid reservoir 10, and when the liquid reservoir 10 is accommodated in the first chamber 511 of the aerosol-generating device, the sealing element 17 is used for sealing a gap between the outer wall of the liquid reservoir 10 and the inner wall of the chamber, so as to prevent the liquid from flowing backwards and overflowing. Further, a stronger abutment is formed between the sealing member 17 and the inner wall of the first chamber 511 with respect to the case 11 of the reservoir 10 and the inner wall of the first chamber 511, and thus the sealing member 17 contributes to more stable accommodation of the reservoir 10 inside the first chamber 511. The sealing element 17 is preferably produced from a flexible silicone material, the sealing element 17 being configured in the form of a ring, an annular groove being provided on the outer wall of the housing 11, in which groove the sealing element 17 is arranged.

In some embodiments, a ledge 151 is provided on the lid 15 of the reservoir 10, the ledge 151 facilitating the user's grip of the reservoir 10. When the liquid reservoir 10 is accommodated in the first chamber 511, the protruding edge 151 abuts against the top end surface of the first chamber 511, so that the liquid reservoir 10 can be stably held in the first chamber 511. When it is desired to replace the reservoir 10, the user can remove the reservoir 10 from the interior of the first chamber 511 by holding the flange 151.
In some embodiments, the first opening 111 is disposed at the top end of the housing 11, the second opening 112 is disposed at the bottom end of the housing 11, the first opening 111 and the second opening 112 are disposed opposite, and the second shutter 13 is disposed on the second opening 112, and the second shutter 13 is preferably disposed as a sealing film, where the sealing film is made of aluminum foil or tin foil or is a flexible silica gel material.

In some examples, during the process of placing the liquid container 10 into the aerosol-generating device, pressing the cap 15 on the liquid container 10 drives the first piercing member 16 and the second piercing member 60 simultaneously, so that the first opening 111 and the second opening 112 can be opened simultaneously by simple pressing action, which is simple and efficient and is beneficial to improving the operation experience of the user. Alternatively, during placement of the reservoir 10 into the aerosol-generating device, the second piercing member 60 is preferentially actuated, the second opening 112 is preferentially opened, the first piercing member 16 is actuated, and the first opening 111 is opened, by further depressing the cap 15 on the reservoir 10. In a further example, the user may also choose to preferentially press the cap 15 of the reservoir 10 to open the first opening 111, and then place the reservoir 10 inside the aerosol-generating device and actuate the second piercing member 60 to open the second opening 112.
