Description

1 / 42 “AEROSOL GENERATOR CARTRIDGE AND AEROSOL GENERATOR SYSTEM”

[001] The present invention relates to an aerosol generating cartridge. The invention also relates to an aerosol generating system comprising the cartridge.

[002] Aerosol generating systems that heat a liquid aerosol generating substrate to generate an inhalable aerosol for delivery to a user are known. In particular, electrically operated portable aerosol generating systems comprising a replaceable cartridge comprising a liquid storage portion containing a supply of liquid aerosol generating substrate and an electrically operated heater configured to heat the liquid aerosol generating substrate to generate an inhalable aerosol are known. Such electrically operated portable aerosol generating systems generally also comprise a reusable aerosol generating device comprising a control circuit and a power source to supply power to the electrically operated heater.

[003] The electrically operated heater typically comprises a resistance heating element in the form of a coil of wire wound around an elongated wick, which carries the aerosol-generating liquid substrate from the liquid storage portion of the cartridge to the coil of wire. During use, an electric current is passed through the coil of wire to heat the aerosol-generating liquid substrate to generate an inhalable aerosol that is drawn into a user's mouth via a mouthpiece.

[004] In other known electrically operated portable aerosol generating systems, the electrically operated heater comprises a resistance heating element located on a heating surface of a porous body, which carries Petition 870260032640, dated 08 / 04 / 2026, page 54 / 106 2 / 42 liquid substrate aerosol generator from the liquid storage portion of the cartridge to the resistance heating element.

[005] It has been found that electrically operated portable aerosol generating systems of the type described above have a number of disadvantages. One of these is dry heating or dry draft. To ensure that a satisfactory aerosol is produced, it is preferable to maintain a sufficient supply of liquid aerosol generating substrate to the heating element during operation to keep the heating element in a wet state. Dry heating arises where an electric current is passed through the heating element when insufficient liquid aerosol generating substrate is being supplied to the heating element. Dry heating can, for example, occur when the supply of liquid aerosol generating substrate in the liquid storage portion of the cartridge is depleted. Dry heating can result in overheating of the heating element. This can lead to thermal decomposition of the liquid aerosol generating substrate.Thermal decomposition of the aerosol-generating liquid substrate can produce undesirable byproducts. Thermal decomposition of the aerosol-generating liquid substrate can result in the production of an unsatisfactory aerosol. Continuous operation of an aerosol-generating system when insufficient aerosol-generating liquid substrate is being supplied to the heating element can thus result in a poor user experience.

[006] In a portable electrically operated aerosol generator system of the type described above, there is a nozzle with a length in the longitudinal direction of the system and with a width and a thickness, the width being greater than the thickness. In this known system, the heater is a porous body with a heating element on a heating surface facing the air outlet. In this system Petition 870260032640, dated 08 / 04 / 2026, page 55 / 106 3 / 42 In a known system, the airflow path through the system is configured so that the airflow approaches an absorption surface of the heater before passing through the heating surface, where the airflow carries the vapor before passing to the aerosol outlet. The inventors identified that, in this known system, the vapor condenses in an amount that provides an unsatisfactory user experience. The inventors identified that a system or cartridge in which there is less condensation would provide an improved user experience.

[007] The invention relates to an aerosol generator cartridge. The aerosol generator cartridge may comprise an aerosol outlet end. The aerosol generator cartridge may comprise a connection end. The aerosol generator cartridge may comprise a longitudinal direction extending between the aerosol outlet end and the connection end. The aerosol generator cartridge may comprise a nozzle. The nozzle may comprise a nozzle housing. The nozzle housing may have a length in the longitudinal direction. The nozzle housing may have a width. The nozzle housing may have a thickness. The width of the nozzle housing may be greater than the thickness of the nozzle housing. The aerosol generator cartridge may comprise a heater. The heater may be disposed in the nozzle housing. The heater may comprise a heating element.Liquid aerosol-forming substrate. The heating element may be for vaporizing a liquid aerosol-forming substrate. The heater may comprise a porous body. The porous body may be for transporting the liquid aerosol-forming substrate to the heating element. The porous body may have a heating surface. The heating surface may face the... Petition 870260032640, dated 08 / 04 / 2026, page 56 / 106 4 / 42 Air outlet. The heating element may be located on the heating surface of the porous body. The aerosol generator cartridge may comprise an aerosol outlet. The aerosol outlet may be at the aerosol outlet end. The aerosol generator cartridge may comprise an air inlet between the aerosol outlet end and the connection end. The air inlet may be in fluid communication with the aerosol outlet. The air inlet may be in fluid communication with the aerosol outlet to define an airflow path, which may also be referred to as an airflow passage. The air inlet may be in fluid communication with the aerosol outlet to define an airflow path through the nozzle housing. The airflow path may extend from the heating element. The airflow path may extend from the heating element to the aerosol outlet.The airflow path may extend from the heating element to the aerosol outlet in the longitudinal direction of the cartridge. The heater may have a length in the longitudinal direction. The heater may have a width. The heater may have a thickness. The width of the heater may be greater than the thickness of the heater. The heater may be oriented so that the width of the heater extends substantially in the same direction as the width of the nozzle housing.

[008] According to the invention, an aerosol generator cartridge is provided. The aerosol generator cartridge comprises: an aerosol outlet end, a connection end, and a longitudinal direction extending between the aerosol outlet end and the connection end; a nozzle comprising a nozzle housing with a nozzle housing length in the longitudinal direction, a nozzle housing width and a nozzle housing thickness, the width of the nozzle housing Petition 870260032640, dated 08 / 04 / 2026, page 57 / 106 5 / 42 being greater than the thickness of the nozzle housing; a heater disposed in the nozzle housing, the heater comprising: a heating element for vaporizing an aerosol-forming liquid substrate; and a porous body for transporting the aerosol-forming liquid substrate to the heating element, the porous body having a heating surface facing the air outlet, the heating element being located on the heating surface of the porous body, an aerosol outlet at the aerosol outlet end, and an air inlet between the aerosol outlet end and the connection end;the air inlet being in fluid communication with the aerosol outlet to define an airflow path through the nozzle housing, the airflow path extending from the heating element to the aerosol outlet in the longitudinal direction of the cartridge, wherein the heater has a length in the longitudinal direction, a width, and a thickness, the width being greater than the thickness, and the heater is oriented so that the width extends substantially in the same direction as the width of the nozzle housing.

[009] In a cartridge where the air inlet is provided between the aerosol outlet end and the connection end, the air passing through the airflow path from the inlet does not need to pass entirely around the porous body from one liquid absorption side of the porous body to the heating surface of the porous body. Instead, the airflow can approach the heater in a lateral direction, from one side of the cartridge. This arrangement has fewer airflow turning points adjacent to the heater. This arrangement provides a smooth airflow that can quickly carry away vapor and prevents a large amount of vapor from remaining in the aerosol generation chamber, which reduces the amount of condensation in the Petition 870260032640, dated 08 / 04 / 2026, page 58 / 106 6 / 42 aerosol generation chamber. This provides a more suitable aerosol at the aerosol outlet and delivers an improved user experience.

[0010] In addition, providing the heater's heating surface facing the aerosol outlet allows for a direct path for the aerosol to the aerosol outlet. This reduces the amount of condensation and provides a more suitable aerosol at the aerosol outlet, resulting in an improved user experience.

[00112] Figure 1B shows a schematic cross-section through the disassembled system 100, but from a side view perpendicular to the front view. The system 100 in Figure 1B is identical to that described in relation to Figure 1A.

[00113] It can be seen in Figure 1B, in comparison with Figure 1A, that the width of the nozzle housing 102 is greater than the thickness of the nozzle housing 103. It can also be seen in Figure 1A that the length of the nozzle housing 101 is greater than the width of the nozzle housing 102. Figure 1B also shows that the nozzle housing 110 is conical, so that the thickness of the nozzle body decreases from the distal end to the proximal end of the nozzle housing 110. Due to this tapering, it can be seen that the cross-sectional area of ​​the nozzle housing 110 perpendicular to the longitudinal axis 500 is smaller at the proximal end of the nozzle housing 110 than at the distal end of the nozzle housing 110.

[00114] Figure 1C shows a schematic cross-section through an assembled embodiment of a system. The system 100 in Figure 1C is identical to that described in relation to Figures 1A and 1B.

The insert 113 is received within the airflow passage opening 122 so that at least a portion of the insert 113 is located within the airflow passage opening 122. A hermetic seal between the insert 113 and the reservoir sealing element is thus formed.

[00116] The support 130 is partially located within the nozzle housing 110, such that the proximal surface of the support 130 contacts the reservoir sealing element 120 to form a liquid-tight seal with the reservoir sealing element 120. Each of the two substrate channel openings 124 of the reservoir sealing element 120 is aligned with a corresponding support fluid channel 136 of the support 130. The support fluid channels 136, substrate channel openings 124, and nozzle housing 110, therefore, define external surfaces of the reservoir 116. The reservoir 116 is shown in Figure 1C filled with aerosol-forming liquid substrate.

[00117] In Figure 1C, the base 140 is coupled to the support 130 by a quick-release connection. A portion of the support 130 is received into the base cavity 142. The electrical contacts of the support 135 are in contact with the electrical connector 145. The base 140 is further coupled to the nozzle housing 110 by a quick-release connection. The base is coupled to the nozzle housing 110 so that the support 130 and the reservoir sealing element 120 are held firmly in place within the nozzle housing 110.

[00118] The nozzle housing 110, the reservoir sealing element 120, the support 130 and the base 140 together form the system cartridge 100.

[00119] The cartridge comprises an airflow path from the cartridge. Petition 870260032640, dated 08 / 04 / 2026, pp. 91 / 106 39 / 42 The cartridge airflow path extends from the base air inlets 148 to the holder air inlets 138 through the space between the base 140 and the holder 130, and from the holder air inlets 138 through the aerosol generation chamber 133 and airflow passage 112 to the aerosol outlet 114.

[00120] As shown in Figure 1C, the cartridge can be attached to the body of the device 150. During use, the user can reversibly attach the cartridge to the body of the device and detach the cartridge from the body of the device 150, for example, when the reservoir 116 is empty of aerosol-forming liquid substrate.

[00121] When cartridge base 140 is coupled to device body 150, a small gap is present between base 140 and device body 150, so that air can enter the base air inlets 148.

[00122] When coupled to the body of device 150, a portion of the base 140 is received within the cavity of device 152, so that the electrical contacts of device 155 are in contact with the electrical connector 145. A complete electrical path is therefore formed from the electrical contacts of device 155 to the electrical connector 145, to the electrical contacts of the support 135 and then to the heating strip 134.

[00123] During use, the user can connect the cartridge to the body of the device 150 and press a button (not shown) located on the side of the body of the device 150. The button is connected to the control circuit 154. The control circuit 154 is configured to control the power supply from the battery 156 to the heating strip 134 through the electrical contacts of the device 155, the electrical contacts of the base 145, and the electrical contacts of the support 135. When the user presses the button, power is supplied from the battery to the heating strip, so that the heating strip increases in temperature. Petition 870260032640, dated 08 / 04 / 2026, pp. 92 / 106 40 / 42 rotation. The aerosol-forming liquid substrate in reservoir 116 is drawn down the fluid channels of the support 136 to the porous body 132 of the heater 139. The porous body 132 absorbs the aerosol-forming liquid substrate by capillarity to the heating surface of the porous body 132, where it is volatilized by the hot heating band 134. This transport of aerosol-forming liquid substrate is illustrated with aerosol-forming liquid substrate transport arrows 171.

[00124] When the user inhales over the mouthpiece housing 110, air is drawn in through the cartridge airflow path. In particular, air is drawn into the base air inlets 148 and then into the support air inlets 138 through the space between the base 140 and the support 130 and from the support air inlets 138 into the aerosol generation chamber 133. The volatilized aerosol-forming substrate condenses within the airflow through the aerosol generation chamber 133 and is drawn into the user's mouth through the airflow passage 112 and aerosol outlet 114. This airflow is illustrated with airflow arrows 172 shown in Figures 1C and 1D.

[00125] Figure 1D also shows a schematic cross-section through an assembled system 100, but from a side view perpendicular to the front view. The assembled system 100 in Figure 1C is identical to that described in relation to Figure 1C.

[00126] As illustrated in Figure 1D, airflow 172 enters the aerosol generation chamber 133 through support air inlets 138 approximately perpendicular to the longitudinal axis 500. The longitudinal axis 500 is substantially parallel to the direction of airflow from the aerosol generation chamber 133, through the airflow passage 112 and to the aerosol outlet 114. The aerosol generation chamber 133, the airflow passage 112 and the nozzle airflow outlet 114 are aligned in a straight line so that Petition 870260032640, dated 08 / 04 / 2026, pp. 93 / 106 41 / 42 the airflow path from the aerosol generation chamber 133, through the airflow passage 112 and to the airflow outlet of the nozzle 114 is straight.

[00127] Figure 2A shows a perspective view of a heater schematic and Figure 2B shows an alternative perspective view of the heater schematic.

[00128] The heating strip 134 is illustrated as arranged on the heating surface of the porous body 132. The heating strip 134 comprises two electrical contacts of the heating strip 363 at opposite ends of the heating surface of the porous body 132. The two electrical contacts of the heating strip 363 are configured to contact the electrical contacts of the support 135, as described above.

[00129] The heating strip further comprises a serpentine heating strip 362 extending between the two electrical contacts of the heating strip 363. The serpentine heating strip 362 is configured to be resistively heated when a current is passed through the serpentine heating strip 362. The heating strip 134 is a metallic strip comprising a metal film. The two electrical contacts of the heating strip 363 are integrally formed with the serpentine heating strip 362.

[00130] Two liquid feed cutouts 364 are defined in the porous body 132. Both liquid feed cutouts 364 are defined on the distal surface of the porous body 132. The two liquid feed cutouts are defined at opposite ends of the porous body 132. When the heater 139 is positioned on the support 130, the aerosol-forming liquid substrate flows from the fluid channels of the support 136 to the corresponding liquid feed cutout 364 and subsequently to the porous body 132.
