Description

[0001] AEROSOL PROVISION DEVICE AND AEROSOL PROVISION SYSTEM

[0002] Technical Field

[0003] This invention is related to the field of aerosol provision, particularly relating to an aerosol provision device and an aerosol provision system.

[0004] Technical Background

[0005] Electronic cigarette-type aerosol provision systems, which heat but do not combust aerosol-generating materials containing aerosol-forming substrates (such as tobacco), generally utilize heaters or similar devices to heat the aerosol-generating materials to a sufficiently high temperature for the generation of aerosol for puffing by the user. Aerosol provision systems typically use batteries to provide power to the heater. The aerosol, when exposed to cold, will generate condensate. If the condensate is not properly collected and treated, on one hand, it is prone to accumulate in the atomization chamber, leading to the condensate being puffed by users along with the aerosol during puffing, affecting the user's puffing experience. On the other hand, if the condensate comes into contact with components such as the battery, it can cause damage to these components in the electronic cigarette technology field.

[0006] Therefore, there is an urgent need for a new structure for the aerosol provision system to solve one or more of these technical issues.

[0108] The present disclosure relates to aerosol delivery systems (which may also be referred to as vapour delivery systems) such as nebulisers or e-cigarettes. Throughout the following description the term "e-cigarette" or "electronic cigarette" may sometimes be used, but it will be appreciated this term may be used interchangeably with aerosol delivery system I device and electronic aerosol delivery system I device. Furthermore, and as is common in the technical field, the terms "aerosol" and "vapour", and related terms such as "vaporise", "volatilise" and "aerosolise", may generally be used interchangeably.

[0109] Aerosol delivery systems (e-cigarettes) often, though not always, comprise a modular assembly comprising a reusable device part and a replaceable (disposable / consumable) cartridge part. Often, the replaceable cartridge part will comprise the aerosol generating material and the vaporiser (which may collectively be called a “cartomizer”) and the reusable device part will comprise the power provision (e.g. rechargeable power source) and control circuitry. It will be appreciated these different parts may comprise further elements depending on functionality. For example, the reusable device part will often comprise a user interface for receiving user input and displaying operating status characteristics, and the replaceable cartridge device part in some cases comprises a temperature sensor for helping to control temperature. Cartridges are electrically and mechanically coupled to the control unit for use, for example using a screw thread, bayonet, or magnetic coupling with appropriately arranged electrical contacts. When the aerosol generating material in a cartridge is exhausted, or the user wishes to switch to a different cartridge having a different aerosol generating material, the cartridge may be removed from the reusable part and a replacement cartridge attached in its place. Systems and devices conforming to this type of two-part modular configuration may generally be referred to as two-part systems / devices.

[0110] It is common for electronic cigarettes to have a generally elongate shape. For the sake of providing a concrete example, certain embodiments of the disclosure will be taken to comprise this kind of generally elongate two-part system employing disposable cartridges. However, it will be appreciated that the underlying principles described herein may equally be adopted for different configurations, for example single-part systems or modular systems comprising more than two parts, refillable devices and single-use disposables, as well as other overall shapes, for example based on so-called box-mod high performance devices that typically have a boxier shape. More generally, it will be appreciated certain embodiments of the disclosure are based on aerosol delivery systems which are operationally configured to provide functionality in accordance with the principles described herein and the constructional aspects of systems configured to provide the functionality in accordance with certain embodiments of the disclosure is not of primary significance.

[0111] As mentioned in the technical background, if condensate is not properly collected, on the one hand, it can easily accumulate in the atomization chamber, leading to the inhalation of condensate by users along with aerosol during puffing, affecting the user's puffing experience. On the other hand, if condensate comes into contact with components such as the battery, it can cause damage to these components. Based on this, this application discloses a new cartridge for an aerosol provision system, aiming to prevent the inhalation of condensate by users during puffing, thereby preserving the user's puffing experience. Simultaneously, it also serves to prevent condensate from coming into contact with components such as the battery, thereby avoiding damage to these components.

[0112] With reference to the accompanying drawings, the specific details of the embodiment of this application will be described.

[0113] Embodiment One

[0114] Figure 1 is a schematic diagram of the three-dimensional structure of the aerosol provision device after removing the device housing described in embodiment one of this application. Figure 2 is a schematic diagram of the structure of the battery top cap of the aerosol provision device described in embodiment one of this application. Referring to Figures 1 to 2, the aerosol provision device in the embodiment of this application generally comprises a battery storage compartment (not shown in the figures), battery top cap 100, battery component 200, and device housing 300. The device housing 300 internally forms the aforementioned battery storage compartment, and the battery component 200 is placed in the battery storage compartment. The device housing 300 also forms an accommodating space for accommodating the battery top cap 100, allowing for the installation of the battery top cap 100. The battery top cap 100 is located at the top of the battery storage compartment.

[0115] Further referring to Figure 2, in a specific embodiment, the battery top cap 100 forms a first cavity 110 and a second cavity 120. The first cavity 110 is in fluid communication with the second cavity 120. The first cavity 110 is connected to the airflow channel of the device (not shown in the figure), and the battery top cap 100 has a top surface 130 and a bottom surface 140 arranged in the height direction of the device. The top surface 130 has a first electrode hole 150, and the first cavity 110 is formed between the top surface 130 and the bottom surface 140. The top surface 130 forms the bottom wall of the second cavity 120, and the top surface has a first opening 160. This application's design allows the collection of condensate through the first cavity. On one hand, it is prone to accumulate in the atomization chamber, leading to the condensate being puffed by users along with the aerosol during puffing, affecting the user's puffing experience. On the other hand, if the condensate comes into contact with components such as the battery, it can cause damage to these components in the electronic cigarette technology field.

[0116] In another specific embodiment, the device further comprises an airflow sensor (not shown in the figure). The battery top cap 100 forms a first cavity 110 and a second cavity 120 inside, and the first cavity 110 is in fluid communication with the second cavity 120. The first cavity 110 is connected to the device's airflow channel (not shown in the figure), and the battery top cap 100 has a top surface 130 and a bottom surface 140 arranged in the height direction of the device. The first cavity 110 is formed between the top surface 130 and the bottom surface 140, and the top surface 130 forms the bottom wall of the second cavity 120. The first cavity 110 is connected to the airflow sensor, allowing the first cavity to form a negative pressure chamber, thereby reducing the overall size of the device.

[0117] As a preferable embodiment, in the embodiment of this application, the system also comprises a controller component (not shown in the figure). Preferably, the battery top cap 100 is further formed with a function chamber 170 for containing a control device. Further referring to Figure 2, in the transverse direction of the device, the projection of the first cavity 110 is overlapped with that of the function chamber 170.

[0118] It can be understood that the controller component comprises at least an air flow sensor (not shown in the figure). A through hole 111 is opened on the side wall of the first cavity 110 near the functional chamber 170, and the air flow sensor is positioned at the end of the through hole 111 away from the first cavity 110. This configuration allows the first cavity 110 to communicate with the air flow sensor through the through hole 111 , creating a negative pressure chamber. The functions related to the negative pressure chamber can be referred to in the prior art, and are not further elaborated here. In this embodiment, by setting the first cavity 110 as a negative pressure chamber, the battery top cap 100 achieves both leak prevention and negative pressure chamber functions, thereby reducing the overall structure of the system.

[0119] As a preferable embodiment, in the embodiment of this application, setting a predetermined distance between the through hole 111 and the bottom wall of the first cavity 110 is aimed at preventing condensate from the bottom wall of the first cavity 110 entering the through hole, causing damage to the air flow sensor. It can be understood that, in cases where product design permits, a larger distance between the through hole and the bottom wall of the first cavity is preferable.

[0120] As a preferable embodiment, in the embodiment of this application, a one-way valve or a waterproof breathable film can be installed in the through hole 111 to further prevent condensate from the bottom wall of the first cavity 110 from entering the through hole and causing damage to the airflow sensor.

[0121] Further referring to Figure 2, in the embodiment of this application, the first cavity 110 and / or the second cavity 120 is provided with a first collecting groove 112 inside, and the first collecting groove 112 is formed on the bottom wall of the first cavity 110 and / or the second cavity 120, and extends along the transverse direction of the device. By utilizing the first collecting groove 112 to adsorb the condensate entering the first cavity 110 and / or the second cavity 120, the device's adsorption capacity for condensate is increased, further enhancing the device's leak-proof effectiveness.

[0122] Preferably, there are multiple first collecting grooves.

[0123] Preferably, by configuring the width of a groove opening of the first collecting groove 112 is greater than the width of a groove bottom of the first collecting groove 112, it facilitates the entry of condensate into the first collecting groove.

[0124] In a specific embodiment, the width of the first collecting groove 112 is set to decrease gradually from a groove opening of the first collecting groove to a groove bottom of the first collecting groove112.

[0125] In another specific embodiment, the first collecting groove 112 is set to be composed of multiple sections in which, along the direction from the groove opening to the groove bottom, the groove width of the multiple sections gradually decreases.

[0126] Preferably, the first collecting groove is a capillary groove. It can be understood that capillary grooves, due to their inherent characteristics, have a certain adsorption capacity for liquids. Using capillary grooves as the first collecting grooves can enhance their adsorption capacity for condensate.

[0127] In a specific embodiment, the groove width of the first collecting groove is any value within the range of 0.2 to 0.5mm, such as 0.2mm, 0.3mm, 0.4mm, 0.5mm, etc. The groove depth is any value within the range of 0 to 10mm, such as 0.5mm, 1mm, 2mm, 5mm, 10mm, etc. Here, not all values are exhaustively listed.

[0128] To further enhance the adsorption capacity of condensate, as a preferable embodiment, in the embodiment of this application, the first cavity 110 also comprises a second collecting groove 113 within the first cavity 110. In a specific implementation, the second collecting groove 113 is positioned on the sidewall of the first cavity 110 and extends along the longitudinal direction of the device.

[0129] Preferably, the end of the second collecting groove 113 is connected to one end of the first collecting groove 112, which is positioned on the bottom wall of the first cavity 110. This arrangement facilitates the condensate to flow along the second collecting groove 113 into the first collecting groove 112, where it is adsorbed by the first collecting groove 112.

[0130] Preferably, the second collecting groove 113 is a capillary groove. It can be understood that capillary groove, due to its inherent characteristics, has a certain adsorption capacity for liquids. Using the capillary groove as the second collecting groove 113 can enhance its ability to adsorb condensate.

[0131] In the embodiment of this application, there is no specific limitation on the specific composition of the battery component 200. Any known battery component can be used in this embodiment without departing from the conceptualization of the present invention. For example, the battery component 200 may comprise components such as a battery core and a controller connected to the battery core, and so on. These details are not explicitly described here.

[0132] Embodiment Two

[0133] The difference from embodiment one is that, in the embodiment of this application, as shown in Figure 3, the second cavity 120' comprises interconnected first part 114 and second part 115, wherein the second part 115 extends along the bottom wall of the first part 114 towards the battery compartment.

[0134] It can be understood that by setting the second cavity 120' to interconnect the first part 114 and the second part 115, the accommodating space of the second cavity 120' can be increased, allowing it to hold more condensate.

[0135] Embodiment Three

[0136] Corresponding to the embodiment one and two, the embodiment of this application discloses an aerosol provision system, as shown in Figures 4 and 5. It comprises a cartridge and an aerosol provision device as described in either embodiment one or two. The cartridge generally comprises an atomization core 400, a first leakage-proof unit 500, a mouthpiece component 700, a liquid storage compartment 800, a cartridge housing 900, and an air inlet 1000. Inside the cartridge housing 900, there is a containment space and an airflow channel. Part of the containment space forms the atomization chamber 410, and another part of the containment space is used to set or partially set the atomization core 400, the first leakageproof unit 500, and the liquid storage compartment 800. The air inlet 1000 connects the airflow channel (not labeled in the diagram) to the external atmosphere of the aerosol provision system. The atomization chamber 410 is in fluid communication through the airflow channel with the air inlet and the outlet of the mouthpiece component 700, allowing aerosol to be drawn by the user from the outlet of the mouthpiece component 700. The first leakage-proof unit 500 is set upstream along the airflow direction in the atomization chamber 410, adsorbing condensate. On one hand, it prevents the condensate from accumulating in the atomization chamber, avoiding the inhalation of condensate by users along with the aerosol during puffing, thus preserving the user's puffing experience. On the other hand, it prevents condensate from coming into contact with components such as the battery, thereby avoiding damage to components like the battery.

[0137] It can be understood that, in the embodiment of this application, the airflow direction refers to the direction in which the external atmosphere enters the airflow channel through the air inlet, sequentially passing through the first leakage-proof unit 500, the atomization chamber 410, and the outlet of the mouthpiece component 700.

[0138] Figure 6 is an exploded diagram of the first leakage-proof described in embodiment three of this application. As shown in Figure 6, in the embodiment of this application, the first leakage-proof unit 500 comprises the third cavity 510, the first holder 520, and the liquid absorbent member 530. The third cavity 510 is configured to be adjacent to the atomization chamber 410 and located upstream of the atomization chamber 410 along the airflow direction. The first holder 520 is configured to have the first bottom face 521 forming the bottom of the third cavity 510 and the first air vent pipe 522 extending from the first bottom face 521 into the third cavity 510. The liquid absorbent member 530 is positioned within the third cavity 510 and has a passing hole 531 , where the passing hole 531 is configured to allow the first air vent pipe 522 to pass through, and the top surface of the passing hole 531 is not lower than the top surface of the first air vent pipe 522. It can be understood that when condensation occurs due to the cooling of the aerosol generated in the atomization chamber, the liquid absorbent member 530, located in the third cavity 510, absorbs the condensate. This prevents the condensate from accumulating in the atomization chamber, avoiding the situation where condensate is inhaled by the user along with the aerosol during puffing, affecting the user's puffing experience. Additionally, it prevents the condensate from coming into contact with components such as the battery, preventing damage to these components. Setting the top surface of the passing hole 531 to be not lower than the top surface of the first air vent pipe 522 allows the liquid absorbent member to absorb more condensate and reduce the amount of condensate falling down through the first air vent pipe 522.

[0139] Further referring to Figure 6, the first holder 520 also comprises the first circumferential wall 523 surrounding the circumferential surface of the third cavity 510 and the second electrode hole 524 opened on the first bottom face 521. The second electrode hole 524 is designed to allow the passage of electrodes. It can be understood that there are two second electrode holes 524, each respectively allowing the passage of a positive electrode and a negative electrode.

[0140] Figure 7 is a schematic diagram of the structure of the first holder of the first leakageproof unit described in embodiment three of this application. As shown in Figure 7, as a preferable embodiment, in the embodiment of this application, on the first holder 520, there are also air cut-off holes 525, which are opened at one end of the first holder 520 away from the third cavity 510. The air cut-off holes 525 form part of the airflow channel, and the airflow volume in the airflow channel is minimized at the location of the air cut-off holes 525. In specific implementations, the axial direction of the air cut-off holes 525 is set at an angle to the length direction of the cartridge. Preferably, the axial direction of the air cut-off holes 525 is perpendicular to the length direction of the cartridge. The number of air cut-off holes 525 comprises at least two, and at least two air cut-off holes are evenly spaced along the circumferential direction of the first holder 520. The air cut-off holes 525 extend in a direction perpendicular to the length direction of the cartridge, and there is a gap between the surface of the air cut-off holes 525 facing the side of the cartridge housing and the cartridge housing, allowing gas to pass through.

[0141] To allow the liquid-absorbent member 530 to absorb condensate as much as possible and prevent condensate accumulation on the side wall of the third cavity 510, as a preferred embodiment, in this embodiment of the present application, the height of the liquid-absorbent member 530 in the depth direction of the third cavity 510 is not less than the depth of the third cavity 510. Preferably, the top surface of the liquid-absorbent member 530 is flush with the top of the third cavity 510. Furthermore, it is preferably set that the liquid-absorbent member 530 fills the third cavity 510, ensuring that the liquid-absorbent member can absorb condensate as much as possible and prevent condensate accumulation on the side wall of the third cavity. It should be noted that the specific material of the liquid-absorbent member is not limited in this embodiment. As long as it can absorb liquid without violating the conceptual framework of the present invention, any material capable of adsorbing liquid can be used as the liquid-absorbent member in this application. As an illustrative example, rather than a restrictive one, the liquidabsorbent member in this embodiment can be made of materials such as cotton. Further referring to Figure 6, the first leakage-proof unit in this embodiment of the present application also comprises a sealing member 540. The sealing member 540 is located at the top of the first holder 520 and covers the opening of the third cavity 510. The sealing member 540 has an opening 541 , and the opening 541 communicates the third cavity 510 with the atomization chamber 410. In specific implementations, the sealing member 540 and the first holder 520 can be connected by a buckle, for example, a connecting buckle 526 is set on the first holder 520, and a connecting hole 542 is provided on the sealing member 540. The connection between the sealing member 540 and the first holder 520 is achieved through the connecting buckle 526 and the connecting hole 542. By placing the sealing member at the top of the first holder, it can prevent condensate from leaking out of the opening of the third cavity when there is excessive condensate in the third cavity.

[0142] Understandably, to allow the passage of electrodes, the sealing member 540 can have a third electrode hole 543. The third electrode hole 543 comprises two, respectively allowing the positive electrode and negative electrode to pass through.

[0143] As a preferable embodiment, in the embodiment of this application, the first leakage-proof unit 500 further comprises a fourth collecting groove (not shown in the figure). The fourth collecting groove (not shown in the figure) is positioned on the bottom wall of the third cavity 510 and extends along the transverse direction of the cartridge shell. By setting the fourth collecting groove on the bottom wall of the third cavity, it is possible to utilize the fourth collecting groove to adsorb a portion of the condensate, further enhancing the leakage-proof effect.

[0144] Preferably, the width of the opening of the fourth collecting groove is greater than the width of the bottom of the fourth collecting groove. This facilitates the entry of condensate into the fourth collecting groove.

[0145] Preferably, the number of the fourth collecting groove can be multiple.

[0146] Preferably, the fourth collecting groove is a capillary groove. It can be understood that capillary groove, due to its inherent characteristics, has a certain adsorption capacity for liquids. Using the capillary groove as the fourth collecting groove can enhance its ability to adsorb condensate.

[0147] As a preferable embodiment, in the embodiment of this application, the aerosol provision system further comprises a second leakage-proof unit 600. The second leakage-proof unit 600 is arranged along the airflow direction between the battery top cap 100 and the first leakage-proof unit 500. By placing the second leakage-proof unit along the airflow direction between the battery top cap and the first leakage-proof unit, the system's absorption capacity for condensate is increased, further improving the leakage-proof effect of the cartridge.

[0148] The second leakage-proof unit 600 is positioned upstream along the airflow direction relative to the first leakage-proof unit 500. Referring to Figure 8, in the embodiment of this application, the second leakage-proof unit 600 generally comprises the fourth cavity 610, the second holder 620, and the third collecting groove 630. The fourth cavity 610 is configured to be in fluid communication with the third cavity 510 through the first air vent pipe 522, allowing fluid containing condensate to enter the fourth cavity 610 from the third cavity 510 through the first air vent pipe 522. The second holder 620 is configured to have a second bottom face 621 forming the bottom of the fourth cavity 610 and a second air vent pipe 622 extending from the second bottom face 621 into the fourth cavity 610. The third collecting groove 630 is configured to be located on the second bottom face 621 and extend laterally along the cartridge. By placing the second leakage-proof unit upstream along the airflow direction from the first leakage-proof unit, the second collecting groove 630 adsorbs condensate entering from the third cavity into the fourth cavity, increasing the absorption capacity of the cartridge for condensate and further improving the leakage-proof effect of the cartridge.

[0149] As a preferable embodiment, in the embodiment of this application, the centerline of the second air vent pipe 622 is intentionally offset from the centerline of the first air vent pipe 522. This configuration ensures that the airflow path between the atomization chamber and the third cavity is offset from the airflow path between the third cavity and the fourth cavity. The intentional offset increases the pathway for condensate to travel from the atomization chamber through the third cavity and the fourth cavity. This design maximizes the absorption of condensate by the first and second leakage-proof units, enhancing the leakage-proof effectiveness.

[0150] Preferably, the top surface of the second air vent pipe 622 is positioned higher than the top surface of the third collecting groove 630. This arrangement aims to prevent condensate from the third collecting groove 630 leaking through the second air vent pipe 622 and reaching below the second holder 620, thus avoiding contamination or damage to the components located underneath.

[0151] Preferably, the third collecting grooves 630 may be multiple in number.

[0152] In a specific embodiment, multiple third collecting grooves 630 are not interconnected.

[0153] In another specific embodiment, multiple third collecting grooves 630 are interconnected, and adjacent third collecting grooves 630 are set at an angle to increase the adsorption capacity for condensate in the third collecting grooves 630.

[0154] Preferably, the width of the opening of the third collecting groove 630 is greater than the width of the bottom of the third collecting groove 630, facilitating the entry of condensate into the third collecting groove.

[0155] Preferably, the third collecting grooves are capillary grooves. It can be understood that capillary grooves, due to their inherent characteristics, have a certain adsorption capacity for liquids. Using capillary grooves as the third collecting grooves can enhance their adsorption capacity for condensate. It can be understood that, for the convenience of electrode penetration, the second holder 620 is also equipped with a fourth electrode hole 623. Preferably, the edge of the fourth electrode hole 623 abuts the bottom of the first holder 620. By setting the edge of the fourth electrode hole to abut the bottom of the first holder, contamination of electrodes by fluids such as condensate can be avoided. Additionally, it prevents fluids like condensate from flowing through the electrode hole to the battery component, preventing damage to the battery component.

[0156] As a preferable embodiment, in the embodiment of this application, the second holder 620 is designed as a sealing member and is used to seal the bottom space of the first holder 520. With this configuration, it not only prevents condensate from leaking out of the fourth cavity 610 when there is an excess amount but also forms a relatively sealed space at the bottom of the first holder 520. This facilitates minimizing fluid flow through the air cutoff hole, reducing fluid flux at the air cutoff hole in the airflow channel.

[0157] It can be understood that the second holder 620 is positioned to cover the end of the first holder 520 away from the third cavity 510. To enhance the sealing effectiveness, the second holder is set to have an interference fit with the first holder. As an illustrative example and not a limiting description, the second holder can be made of silicone material.

[0158] Figure 9 is a schematic diagram of the liquid storage compartment structure described in embodiment three of this application. As shown in Figure 9, the internal structure of the liquid storage compartment 800 forms a liquid storage chamber 810, which is intended to accommodate aerosol-generating materials such as e-liquid. Inside the atomization core 400, there is an atomization chamber 410 designed to accommodate the heating element. The atomization chamber 410 is in fluid communication with the liquid storage chamber 810 so that the aerosol-generating material in the liquid storage chamber 810 can enter the atomization chamber 410 and form aerosol after being heated by the heating element. As a preferable embodiment, in the embodiment of this application, the liquid storage compartment 800 comprises an outer wall 820. The outer wall 820 of the liquid storage compartment 800 can be integrally formed with the cigarette shell 900, meaning that the outer wall 820 constitutes a part of the cigarette shell 900. Alternatively, the outer wall 820 and the cigarette shell 900 can be independent components. In a specific implementation, the outer wall 820 and the cigarette shell 900 are independent components, with the outer wall 820 covering the outside of the atomization core 400. The liquid storage chamber 810 is collectively surrounded by the outer wall 820 and a portion of the surface of the atomization core 400. Thus, along the height direction of the aerosol provision system, the liquid storage chamber 810 is positioned above the atomization core 400 and the atomization chamber 410.

[0159] Figure 10 is a schematic diagram of the structure of the atomization core described in embodiment three of this application. As shown in Figure 10, the atomization core comprises a heater, an atomization chamber for accommodating the heater, a first fixing component 420, a second fixing component 430 for securing the heater, and an airway silicone component 440. The heater and the airway silicone component 440 are both clamped between the first fixing component 420 and the second fixing component 430. The heater comprises stacked heating bodies 451 and oil guide bodies 452, with the heating bodies 451 positioned between the oil guide bodies 452 and the airflow channel. As an illustrative, non-limiting example, the heating bodies 451 have a mesh structure, with the mesh holes being circular or any polygonal shape. The heating bodies 451 have an atomization surface, and the atomization surface is parallel to the length direction of the system.
