Detailed Description

To facilitate an understanding of the present application, the present application is described in more detail below with reference to the accompanying drawings and detailed description.

One embodiment of the present application provides an aerosol-generating system for atomizing a liquid substrate to generate an aerosol for inhalation. The aerosol-generating systems of the present disclosure may also be characterized as aerosol delivery or drug delivery articles. Accordingly, such devices or systems may be adapted to provide one or more substances (e.g. flavouring agents and/or pharmaceutically active ingredients) in inhalable form or state. For example, the inhalable substance may be substantially in the form of an aerosol (i.e. a suspension of fine solid particles or liquid droplets in a gas). Accordingly, the liquid substrate to be aerosolized may then be a liquid precursor that includes the flavoring and/or the pharmaceutically active ingredient prior to forming the aerosol. In a more preferred embodiment, the liquid matrix is a medicament for the production of an inhalable medicament; the aerosol-generating system is a drug delivery device that can be used as a medical treatment.

Figures 1 and 2 show schematic diagrams of an aerosol-generating system in one embodiment; the system typically includes several components disposed within an outer body or housing (which may be referred to as a housing). The overall design of the outer body or housing may vary, and the pattern or configuration of the outer body which may define the overall size and shape of the aerosol-generating system may vary. Typically, a body shaped like an elongated rod or bar may be formed by a single unitary housing, or the housing may be formed by two or more separable bodies. For example, the aerosol-generating system may have a control body at one end with a housing containing one or more reusable components (e.g., a battery such as a rechargeable battery and/or a rechargeable supercapacitor, and various electronics for controlling operation of the article), and at the other end an outer body or housing that can be removably coupled and contains a disposable portion (e.g., a disposable liquid-containing source, a cartridge).

Further in the implementation shown in fig. 1 and 2, the aerosol-generating system comprises:

an aerosol-generating device 100, and a liquid source 200 that may be disposable or reusable. In some alternative implementations, the liquid source 200 may be prepared in the form of a capsule, sac or the like, having stored therein a liquid substrate that may be atomized by the aerosol-generating device 100 to generate an aerosol; in use the liquid source 200 may be received into the aerosol-generating device 100 or removed from the aerosol-generating device 100 by user manipulation. Generally in some embodiments, when a user needs to draw a puff, the liquid source 200 is received into the aerosol-generating device 100, which in turn may cause the aerosol-generating device 100 to take in the liquid substrate within the liquid source 200 and atomize to generate an aerosol; when the liquid substrate within the liquid source 200 is exhausted, the user may then remove the liquid source 200 from the aerosol-generating device 100, for replacement, or the like.

In one implementation, further referring to fig. 2-4, the liquid source 200 is generally configured in a cylindrical shape, comprising:

an outer sidewall 220 substantially annularly disposed; in one embodiment shown in FIG. 4, outer sidewall 220 is substantially elliptical-cylindrical in shape;

a top wall 210 located at a first end of the outer sidewall 220 in the axial direction and sealing the outer sidewall 220 at the first end of the outer sidewall 220;

a rupturable wall 240 at a second end of the outer sidewall 220 in the axial direction.

In some embodiments, a reservoir 250 for storing a liquid matrix is formed by at least a partial hollow interior of the outer sidewall 220. Or in practice, the outer sidewall 220, the rupturable wall 240 and the top wall 210 together define a reservoir 250 for storing the liquid substrate.

In practice, the rupturable wall 240 is at least partially capable of rupturing or rupturing upon squeezing or puncturing to form a rupture or rupture opening to permit egress of the liquid matrix from the reservoir 250 for aerosolization.

In some embodiments, the top wall 210 and the outer sidewall 220 are coupled and connected by molding from a moldable material. Both the top wall 210 and the outer side wall 220 are substantially rigid.

In some embodiments, the rupturable wall 240 may be a flexible sealing membrane, or a rigid film, or the like. The rupturable wall 240 may comprise a metal foil, a polymer film, or the like.

Further in implementation, the top wall 210 is a portion for a user to operate the liquid source 200 by finger gripping, applying force in the above operations; while the operation portion 210 has a larger cross-sectional area than the outer wall 220 in configuration for the convenience of the user's operation, it is advantageous for the convenience of the user's operation.

As further shown in fig. 2-4, the liquid source 200 further comprises:

a flexible member 230; in one embodiment shown in the figures, flexible member 230 is configured as a ring that surrounds or is bonded to outer sidewall 220; and the flexible member 230 is protruded from the surface of the outer sidewall 220.

In one implementation, the flexible element 230 is configured to be at least partially squeezed or compressed by the aerosol-generating device 100 when the liquid source 200 is received within the aerosol-generating device 100, thereby forming an interference fit of the liquid source 200 and the aerosol-generating device 100 such that the liquid source 200 is substantially stably received in the aerosol-generating device 100 without loosening or coming loose.

In still other implementations, the flexible element 230 also serves to seal the joint gap between the aerosol-generating devices 100 when the liquid source 200 is received within the aerosol-generating device 100, to prevent leakage or the like of the gap between them.

As further illustrated in fig. 2-4, the liquid source 200 may be received from one or more angles in the aerosol-generating device 100. In particular, the substantially cylindroid liquid source 200 is centrosymmetric; in practice, the liquid source 200 can be received into the aerosol-generating device 100 at the angle shown in fig. 2, or after being rotated around an axis by 180 degrees.

As further shown in fig. 1-3, the body shape of the aerosol-generating device 100 is configured to be cylindrical; in the implementation shown in the figures in particular, the body of the aerosol-generating device 100 has a length direction, a width direction and a thickness direction; and the length dimension of the body of the aerosol-generating device 100 is greater than the width dimension and the width dimension is greater than the thickness dimension.

a proximal end 110 and a distal end 120 opposite along the length; and a left side end 130 and a right side end 140 opposite in the width direction. In use, the proximal end 110 is generally the end that is proximal to the user.

In some embodiments, the aerosol-generating device 100 may comprise a separate, individual housing that may be formed from any of a number of different materials. The housing may be formed of any suitable structurally sound material. In some examples, the housing may be formed from a metal or alloy, such as stainless steel, aluminum, or the like. Other suitable materials include various plastics (e.g., polycarbonate), metal-plated plastics (metal-plated plastics), ceramics, and the like.

Further in some embodiments, the housing of the aerosol-generating device 100 is configured to include:

an upper housing 11 proximate proximal end 110; and a lower housing 12 proximate distal end 120. In practice, the upper housing 11 and the lower housing 12 together define a housing body of the aerosol-generating device 100.

Further in the implementation shown in the figures, the proximal end 110 of the aerosol-generating device 100 is defined by the upper housing 11, and the distal end 120 of the aerosol-generating device 100 is defined by the lower housing 12.

In some embodiments, upper housing 11 and lower housing 12 are substantially non-removable or inseparable by a user after assembly.

Further in some embodiments, the upper housing 11 is rigid. At least a portion of the surface of the lower housing 12 is flexible.

Further in accordance with the preferred embodiment shown in fig. 3, lower housing 12 includes a rigid inner layer 121 and a flexible cover layer 122 wrapped or formed over rigid inner layer 121; in turn, rigid support and attachment is provided in practice by rigid inner layer 121 and surface flexibility is provided by flexible cover 122. In some embodiments, the rigid inner layer 121 may include a metal, an organic polymer, or the like; the flexible coating 122 may include silicone, elastomer, flexible resin, and the like.

In some embodiments, rigid inner layer 121 and flexible cover layer 122 of lower housing 12 are formed by two-shot molding of two moldable materials in a mold and curing, respectively. The rigid inner layer 121 and the flexible covering 122 obtained by two-shot injection molding are substantially inseparable.

In a more preferred implementation, particularly shown in fig. 3, the aerosol-generating device 100 comprises:

a push-button switch 30, which in use a user may activate or turn on the aerosol-generating device 100 by pressing the push-button switch 30, causing the aerosol-generating device 100 to aerosolize a liquid substrate derived from the liquid source 200 to generate an inhalable aerosol.

In some embodiments, the key switches 30 are disposed on the lower case 12; and the key switch 30 is disposed at the left end 130.

With further reference to fig. 1 and 2, the aerosol-generating device 100 comprises:

In some embodiments, the mouthpiece 20 is hollow and cylindrical.

In some embodiments, at least a portion of the suction nozzle 20 proximate the suction opening A is shaped in a flat manner. Specifically, in fig. 1, at least a portion of the suction nozzle 20 near the suction opening a has a width dimension w1 greater than a thickness dimension h1, and is thus shaped in a flat shape. Meanwhile, the air inlet a is also flat with a width dimension larger than a thickness dimension. At the same time, at least part of the suction nozzle 20 has a cross-sectional area that gradually decreases in a direction approaching the suction opening A.

In one embodiment according to fig. 3, the aerosol-generating device 100 is provided with a substantially circular insertion groove 112; accordingly, the connection part 22 of the mouthpiece 20 facing away from the air inlet a, is inserted or extends at least partially into the insertion groove 112 in assembly to connect with the aerosol-generating device 100. Accordingly, the cross-sectional area of the connecting portion 22 is smaller than the maximum cross-sectional area of the suction nozzle 20. In some embodiments, the cross-section of the insertion slot 112 is substantially circular; and, the insertion groove 112 has a depth of about 4-10 mm.

Further in a more preferred embodiment as shown in fig. 1, the distance d1 in the width direction of the aerosol-generating device 100 from the left end 130 of the free end of the mouthpiece 20 has such a feature that the user's fingers can simultaneously smoothly press or operate the push switch 30 when the user's lips are sucking on the suction opening a. Alternatively, the distance d2 between the mouthpiece 20 and the key switch 30 along the length of the aerosol-generating device 100 may be of such a nature that the user's fingers can simultaneously smoothly press or operate the key switch 30 when the user's lips are sucking on the suction opening a.

In some embodiments, the distance d1 of the free end of the mouthpiece 20 relative to the left side end 130 in the width direction of the aerosol-generating device 100 is greater than 15 mm; more preferably, the distance d1 is greater than 20 mm; in the implementation shown in the figures, the distance d1 is 34 mm.

In the implementation shown in this figure, the above atomizing mechanism 40 comprises at least a vibratable element 42, and the liquid substrate transferred onto the vibratable element 42 is atomized into aerosol by mechanical vibration. In an alternative implementation, vibratable element 42 may be a generally plate-like ultrasonically-vibrating member or a plate-like piezoelectric ceramic; or an ultrasonic atomizing sheet proposed in, for example, patent No. CN 112335933A. These vibratable elements 42, in use, break up the liquid matrix by high frequency vibration (preferably at a frequency of 1.7MHz to 4.0MHz, outside the human auditory range in the ultrasonic range) to produce a naturally suspended aerosol of particles, which is output to the mouthpiece 20.

In a typical implementation, the above aerosolizing mechanism 40, and particularly the vibratable element 42, is further activated or actuated by a user by operating the key switch 30.

Further in accordance with the preferred implementation of fig. 5-10, the aerosol-generating device 100 further comprises:

a container 50 proximate the proximal end 110; the container 50 is located within the upper housing 11 substantially after assembly. In practice, a receiving chamber 510 for receiving and containing the liquid source 200 is at least partially defined by the space within the container 50. In some embodiments, the container 50 is further formed with a liquid transfer passage 520 for transferring liquid matrix originating from the liquid source 200 to the atomizing mechanism 40, in particular the vibratable element 42.

In arrangement, both the container 50 and the atomizing mechanism 40 are housed and held within the upper housing 11; the container 50 is relatively close to the right side end 140 and the aerosolization mechanism 40 is relatively close to the left side end 130.

As further shown in fig. 5-10, a receiving chamber 510 defined within the container 50 is closer to the proximal end 110 than the liquid transfer channel 520. Also provided within the container 50 are:

a piercing mechanism 60 at least partially exposed in the receiving chamber 510 for piercing the rupturable wall 240 of the liquid source 200 when the liquid source 200 is received in the receiving chamber 510; thereby releasing the liquid matrix within the liquid source 200 to the liquid transfer channel 520 after puncturing.

In one embodiment shown in fig. 9, lancing mechanism 60 includes:

a piercing member for piercing the rupturable wall 240 of the liquid source 200. In this embodiment, the piercing member is movably, in particular rotatably, disposed within the container 50.

The piercing member includes at least first and second elongated radial arms 610 and 620; the first radial arm 610 and the second radial arm 620 have an angle therebetween. As shown, the first radial arm 610 and the second radial arm 620 have an obtuse angle therebetween that is greater than 90 degrees.

A connecting member 63 for stably mounting and connecting the piercing mechanism 60 within the container 50. Specifically, a plug hole 55 is provided in the container 50, and the connector 63 has a pin portion 632, and the pin portion 632 is inserted into the plug hole 55 during assembly to be stably connected to the container 50. The coupling member 63 also has a base portion 631, the base portion 631 being primarily for mounting a piercing member; in the figure, the base portion 631 is further provided with a mounting groove 633 for mounting a puncture tool.

A pin 64 passing through the first mounting hole 634 of the base portion 631 and the second mounting hole 613 of the puncture tool in this order; and then the piercing member is stably coupled and held to the base portion 631 of the coupling member 63 by the pin 64 after assembly; and the assembled piercing member can rotate about pin 64.

In the above embodiment, the lancing mechanism 60 is not detachable after assembly of the lancing mechanism 60; and thus the lancing mechanism 60, is at least not removable or extendable out of the receiving chamber 510 to the open mouth, improving the safety of the device in terms of preventing the lancing mechanism 60 from causing a puncture wound or the like on a user's finger during use.

At the same time, the lancing mechanism 60 is essentially distal to the opening of the receiving chamber 510 and abuts against the inner bottom wall of the receiving chamber 510 distal to the opening; it is advantageous to prevent the user from contacting the lancing mechanism 60 in changing the fluid source 200, to avoid scratching or pricking the user's fingers during operation, and to improve the safety of the device.

Or in other variations, the first radial arm 610 is a telescopically linearly movable arrangement; the rupturable wall 240 of the liquid source 200 can be pierced by linear movement.

In some embodiments, the second mounting aperture 613 is substantially located at the connection of the first radial arm 610 and the second radial arm 620.

In some embodiments, the first radial arm 610 is substantially in the shape of a thin plate; the free front end 611 of the first radial arm 610 is configured in the shape of a relatively thin or sharp or wedge-shaped tip, such that puncturing by the free front end 611 is advantageous in use.

In some embodiments, the first radial arm 610 is further provided with a first protrusion 612. Specifically, the first protrusions 612 are formed on both surfaces of the first radial arm 610 in the thickness direction. And, the first protrusion 612 has a gradually decreasing protrusion height at least partially in a direction approaching the free front end 611; so that at least a portion of the first protrusion 612 near the free front end 611 is inclined. It may be advantageous to enlarge the opening of rupturable wall 240 by first projection 612 after free leading end 611 has punctured rupturable wall 240 of liquid source 200.

In some embodiments, second radial arm 620 has a free end facing away from first radial arm 610; the second radial arm 620 has an increased volume portion 621 at the free end. At least a part of the surface of the volume-increased portion 621 is formed to be inclined.

In some embodiments, the piercing member comprises, at least in part, a metal; alternatively, first radial arm 610 comprises metal; the first radial arm 610 includes a free end 611 made of a metal material, which has suitable hardness and processing convenience, and is advantageous for puncturing.

As further shown in fig. 5-7, a biasing element is also provided on the container 50 for biasing or resetting the first radial arm 610 toward the first position with a biasing force. Specifically, a magnetic body 53 is included in the drawing; correspondingly, the free front end 611 of the first radial arm 610 comprises a magnetic metal or alloy; the first arm 610 is magnetically attracted and stably bonded to the inner surface of the container 50 by the magnetic body 53. In alternative implementations, the magnetic metal or alloy includes iron, cobalt, nickel, or alloys containing at least one of the foregoing, such as stainless steel, iron-aluminum alloys, permalloy, and the like.

Or in a further modified embodiment, the above magnetic body 53 may be replaced with an elastic member such as a torsion spring, a spring, etc., and the first radial arm 610 is returned in a direction away from the proximal end 110 by the elastic force; such that the free leading end 611 of the first radial arm 610 is biased or biased generally away from the proximal end 110.

As further shown in fig. 5-7, a stop tab 54 is also provided within the container 50; when the liquid source 200 is received into the receiving chamber 510, the liquid source 200 is stopped against the stop catch 54. Of course, it is primarily the rigid outer sidewall 220 of the liquid source 200 that abuts the stop catch 54.

Further in practice, the process of lancing mechanism 60 lancing liquid source 200 is illustrated with reference to FIGS. 5-7. Specifically, the method comprises the following steps:

the first position of the lancing mechanism 60 before the liquid source 200 is received into the receiving chamber 510 of the container 50 is shown in fig. 5. In the first position, the first radial arm 610 of the puncturing member is magnetically attracted by the magnetic body 53 and is stably attached or combined to the inner surface of the container 50; the first radial arm 610 is substantially horizontal. And in the first position, second radial arm 620 is relatively closer to proximal end 110, in a tilted position relative to first radial arm 610.

Fig. 6 shows a schematic view of the liquid source 200 partially received to a state where the receiving chamber 510 is in contact with the second radial arm 620; for placing the liquid source 200 into the receiving chamber 510 in the direction of the arrow R3, the rigid outer sidewall 210 of the liquid source 200 first contacts and abuts the free end of the second radial arm 620. The user continuing to manipulate the liquid source 200 further into the receiving chamber 510 in the direction indicated by R3 will press on the free end of the second radial arm 620, causing the second radial arm 620 to pivot about the pivot 64 as indicated by the arrow R41; at the same time, the second radial arm 620 correspondingly drives the first radial arm 610 to rotate around the pin 64 as indicated by an arrow R42.

Further according to what is shown in fig. 6 and 9, it is advantageous for the contact or abutment area with the rigid outer side wall 210 of the liquid source 200 to be raised by the volume increasing portion 621. And, the liquid source 200 is partially received into the receiving chamber 510, the direction of rotation R41 of the second radial arm 620 being distal from the proximal end 110, and the direction of rotation R42 of the first radial arm 610 being toward or near the proximal end 110.

Fig. 7 shows a schematic view of the liquid source 200 fully received into the receiving chamber 510 in a second position. In this second position, the liquid source 200 forms a stop against the stop catch 54; the second radial arm 620 is pressed by the liquid source 200 into engagement or attachment with the inner surface of the container 50; and the free forward end 611 of the first radial arm 610 at least partially pierces the rupturable wall 240 of the source 200 and extends into the reservoir chamber 250 to release the liquid matrix. In this embodiment, however, the first radial arm 610 is tilted relatively closer to the proximal end 110 than the second radial arm 620. And as can be seen, the first radial arm 610 and/or the second radial arm 620 rotate from the first position to the second position by less than 90 degrees.

In a more preferred implementation shown in fig. 9, the extension h3 of second radial arm 620 is longer than the extension h2 of first radial arm 610; based on a lever-like principle, it is more labor-saving for the user to actuate the rotation and puncturing of the first radial arm 610 by pressing the second radial arm 620 when receiving the liquid source 200 into the receiving chamber 510. In some preferred implementations, the extension length h3 of second radial arm 620 is between 8 and 15 mm; the extension length h2 of the first radial arm 610 is between 3 mm and 8 mm.

According to the above, a lever with the pin 64 as a fulcrum is formed between the first radial arm 610 and the second radial arm 620; and the second radial arm 620 is rotated about the pin 64 or pivot point by the first radial arm 610. Of course, the actuation or movement of the first radial arm 610 is simultaneous or synchronized with the movement of the second radial arm 620.

According to a preferred implementation shown in fig. 9, the first radial arm 610 and/or the second radial arm 620 are each elongated and plate-like. And the length dimension of the first radial arm 610 is greater than the width dimension, and the width dimension of the first radial arm 610 is greater than the thickness dimension. Similarly, the length dimension of second radial arm 620 is greater than the width dimension and the width dimension of second radial arm 620 is greater than the thickness dimension.

In some embodiments, the extension length h2 of the first radial arm 610 may ensure that the free leading end 611 of the first radial arm 610 is not abutted or contacted by the outer sidewall 210 of the fluid source 200 during operation. Alternatively, the free leading end 611 is configured with a circular arc or wedge shaped cut-out to avoid the outer side wall 210 of the liquid source 200.

And, the first section 5210 is substantially obliquely disposed.

As further shown in fig. 10, the upper housing 11 also defines a holding space 113 for accommodating and holding the atomizing mechanism 40; the atomizing mechanism 40 is basically accommodated and held in the holding space 113.

Further in one embodiment shown in fig. 10, to facilitate close engagement of the atomizing mechanism 40 with the liquid delivery channel 520; the first bracket 41 has a joint part 411 which is at least partially protruded; when the atomizing mechanism 40 is fitted into the holding space 113, the fitting portion 411 at least partially surrounds and surrounds the wall forming the second section 5220, thereby stabilizing the fitting.

In one embodiment of fig. 10, the walls defining the second block 5220 are further provided with sealing elements 5221, and the sealing elements 5221 provide sealing to their joint gaps when the joint portion 411 surrounds and surrounds the walls forming the second block 5220.

Similarly, the second bracket 42 is also provided with a sealing element 44 for providing a seal between the inner wall of the holding space 113 and the atomizing mechanism 40 when the atomizing mechanism 40 is fitted in the holding space 113.

After assembly, the connecting portion 22 of the suction nozzle 20 is abutted against the second bracket 42 of the atomizing mechanism 40, as shown in fig. 3. Of course, the atomizing mechanism 40 is not removable after assembly.

Flow of air flow in suction referring to fig. 3, the suction nozzle is provided with one or more air inlets 21 near the connecting portion 22. The external air enters the aerosol output channel 23 of the mouthpiece 20 from the air inlet 21 as shown by an arrow R2, and carries the aerosol in the aerosol output channel 23 to the air inlet a for inhalation by the user.

As further shown in fig. 11, the aerosol-generating device 100 further comprises:

an inner housing 13, the inner housing 13 and the lower housing 12 together defining a closed first space 123 substantially within the lower housing 12; the first space 123 is a space for mounting the battery cell 150 and/or the circuit board 160.
