In another embodiment, the filter material 105 and/or the filter 104 do not contain nicotine, such that nicotine is not contained in the filter material housing 100 of the filter 104.

In an exemplary embodiment, nicotine may be contained in a reservoir 106 proximate the filter housing 100, with the reservoir 106 in fluid communication with the filter housing 100 (see example in FIG. 5). This nicotine may be used instead of or in addition to the nicotine that is included in the filter material 105 and/or the filter housing material 100.

In one exemplary embodiment, the flavor and/or nicotine are contained in the vaporizer formulation, and the flavor and/or nicotine vaporizer formulation is then introduced into the filter material 105. In another embodiment, the vaporizer formulation is introduced into the filter material 105 separately from flavor and/or nicotine. A pre-formulated vaporizer is a material or combination of materials that is converted into vapor. The terms “vapour,” “aerosol,” and “dispersion” are used interchangeably and are intended to cover any substance generated or released by the claimed devices and their equivalents. The vaporizer formulation may also be an aerosol formulation or a dispersant formulation.

In an exemplary embodiment, the formulated vaporization formulation is a liquid, solid, and/or gel formulation, including, but not limited to, water, granules, solvents, active ingredients, ethanol, plant extracts, natural or artificial flavoring agents, and/or at least one vapor producing substance such as glycerin and propylene glycol.

In an exemplary embodiment, the at least one vaporizing agent of the finished vaporization composition comprises diols (such as propylene glycol and/or 1,3-propanediol), glycerin, and combinations or subcombinations thereof. Varying amounts of the vapor-generating agent may be used. For example, in some exemplary embodiments, the at least one vaporizing agent is contained in an amount ranging from about 20 percent by weight, based on the weight of the finished vaporizing composition, to about 90 percent by weight, based on the weight of the finished vaporizing composition (eg, the steam generating agent ranges from about 50 percent to about 80 percent, or from about 55 percent to 75 percent, or from about 60 percent to 70 percent), and so on. Additionally, in an exemplary embodiment, the formulated vaporization composition has a diol to glycerol weight ratio that ranges from about 1:4 to 4:1, wherein the diol is propylene glycol or 1,3-propanediol, or combinations thereof. In an exemplary embodiment, this ratio is approximately 3:2. Other amounts or ranges may be used.

In an exemplary embodiment, the finished vaporization composition also contains water. Various amounts of water can be used.

Other amounts or percentages may be used. For example, in an exemplary embodiment, the remainder of the finished vaporizing composition that is not water (and nicotine and/or flavor compounds) is a vaporizing agent (described above), wherein the vaporizing agent contains between 30 percent up to 70 percent by weight of propylene glycol, and the remainder of the vapor-forming substance is glycerin. Other amounts or percentages may be used.

In an exemplary embodiment, the formulated vaporization composition contains at least one flavoring agent in an amount ranging from about 0.2 percent to about 15 percent by weight (for example, the amount of flavoring agent may be in the range from about 1 percent to 12 percent, or from about 2 percent to 10 percent, or from about 5 percent to 8 percent). In an exemplary embodiment, the formulated vaporization composition contains nicotine in an amount ranging from about 1 percent by weight to about 10 percent by weight (e.g., the nicotine content is in the range from about 2 percent to 9 percent, or from about 2 percent to 8 percent, or from about 2 percent to 6 percent). In one exemplary embodiment, the non-nicotine and/or flavoring portion of the finished vaporization formulation contains 10-15 percent by weight water, with the remainder of the non-nicotine and non-flavoring portion of the formulation being a mixture of propylene glycol and the release agent. steam, the mixture having a ratio that ranges from about 60:40 to 40:60 by weight. Other combinations, quantities or ranges may be used.

Both sections 70/72 may contain a corresponding housing 6b/6a, and the sections may be connected by a connecting structure 75. The steam thus generated is removed from the device 60 by means of an insert 8 at the mouth end. In an exemplary embodiment, one or more air inlet openings 40 are contained in the housing 6a and/or housing 6b (either the first section 70 or the second section 72 of the device 60). Housings 6a/6b in Fig. 3 may have the same or different shapes, such as, for example, cylindrical, square, rectangular, triangular, polygonal, curved, irregular and so on. In an exemplary embodiment, one or more air inlets 40 are used to create an air flow path through the device 60 that can exit the mouthpiece insert 8, with the heater 14 and filter 104 being in the path of or otherwise exposed to the air flow. . In an exemplary embodiment, the control system 1 is in fluid communication with the air flow path.

In an exemplary embodiment, the first section 70 includes a filter 104. In the first section 70, the filter 104 is positioned to place the filter housing 100 in the path of the steam flow 124 generated by the device 60. The steam 124 leaving the heater 14 passes through the filter housing 100 In this manner, filter 104 may physically filter vapor 124 while also creating downstream vapor 124a that contains entrained flavor, nicotine, and/or formulation for vaporization from filter 104, as described in more detail below. The terms "vapour", "aerosol" and "dispersion" are used interchangeably and are intended to cover any substance generated or released by the devices and/or components of the claimed devices and their equivalents.

In an exemplary embodiment, the filter 104 is sized such that the sides of the containing structure 103 are pressed into the outer air passage 9a, or the second (enlarged) outer air passage 9b (note that in FIG. 3, the filter 104 is shown only in the second outer passage 9b for air) or both if the device 60 includes more than one filter 104. In an exemplary embodiment in which the filter 104 does not include a housing structure 103, the filter 104 may be sized such that the filter material 100 is pressed into the outer passage 9a , 9b or both. The filter 104 must be positioned downstream of the heater 14 and may be located near the insert 8 on the mouthpiece end for the device 60. As an alternative to press-fitting, the filter 104 may instead be held in place by adhesive, set screws, a snap-fit connection structure or any other structure required to hold the filter 104 in place within the first section 70.

In the exemplary embodiment shown in FIG. 3, the housing structure 103 may be located at one or both ends 100a of the filter material housing 100. In an exemplary embodiment, the housing structure 103 includes grids and/or porous material as described above to allow steam 124 to flow freely through the filter material housing 100.

In another embodiment, as described above, the filter housing 100 may consist entirely of the filter 104, such that the housing structure 103 is not present. Or, the filter 104 may only have a housing structure 103 on the sides 100b of the filter material housing 100, such that one or both ends 100a of the filter material housing 100 are open (for example, the housing structure 103 may not be present at the ends 100a).

In an exemplary embodiment, filter 104 is attached within the first section 70. In this embodiment, the first section 70 may be disposable. In another embodiment, the filter 104 is temporarily retained within the first section 70, such that the filter 104 is capable of being removed and replaced before the end of the effective life of the first section 70, such that the first section 70 can be reusable and/or reused with replacement filters 104. In this embodiment, the filter 104 may be provided with the addition or refilling of the flavor system, nicotine, and/or vaporizer formulation within the filter 104, such that the filter 104 can then be reinstalled into the first section 70. In another embodiment, the filter 104 is configured with the possibility of removal and replacement with a new filter 104, while the filter 104 may be disposable. Or, the housing 103 of the filter 104 may be removable or remain attached within the first section 70, wherein only the filter housing 100 can be removed from the housing 103 and replaced, such that the housing 103 is reusable and the filter housing 100 is replaceable. . In yet another embodiment, instead of removing and replacing the filter 104, or in addition to removing and replacing the filter 104, the first section 70 may provide access to the filter media housing 100 and/or the filter 104 to allow the addition or refilling of the flavor, nicotine, and/or system. the finished composition for evaporation into the housing filter material 100 and/or filter 104.

In an exemplary embodiment, reservoir 20 contains a supply of ready-to-evaporate composition 22 heated by heater 14 to generate steam, wherein this supply of ready-to-evaporate composition 22 is separate from the ready-to-evaporate composition introduced into the filter material 105 of the housing filter material 100. In an exemplary embodiment, In an embodiment, the vaporizer formulation 22 contains a flavor and/or nicotine that is the same flavor and/or nicotine described above, or alternatively that is different from the flavor and/or nicotine described above, or alternatively a vaporizer formulation 22 is described. may not contain other flavoring and/or nicotine. In an exemplary embodiment, flavor and/or nicotine may be provided as flavor and/or nicotine in filter housing 100 as steam generated by heater 14 flows through filter housing 100.

In an exemplary embodiment, the heater 14 is in communication with the internal passage 10. In the exemplary embodiment, the internal passage 10 is cylindrical in shape, although the internal passage 10 may also have a different shape and may have, for example, a cross-sectional profile that is square, rectangular, triangular, polygonal, irregularly shaped, and so on. In an exemplary embodiment, heater 14 is made of iron aluminide (eg, FeAl or Fe ₃ Al).

As mentioned above, heater 14 is located upstream of filter 104. Heater 14 heats the finished vaporization composition 22 to produce steam 124, wherein steam 124 is heated to such an extent that warm steam 124 can at least partially be released (e.g. vaporize, release, etc.) flavor, nicotine, and/or formulation ingredients to vaporize into filter housing 100 as steam 124 flows through filter housing 100 to produce downstream steam 124a that exits filter 104. In an exemplary embodiment, the heater 14 is located at some distance from the filter housing 100 and/or the filter 104, such that the filter housing 100 is indirectly heated also by convection. In an exemplary embodiment, the heater 14 is located in a passage with a smaller diameter and/or a smaller cross-sectional area for air flow (for example, in the internal passage 10) compared to the passage (air passage 9b) containing the filter 104. In other exemplary embodiments, the channel containing the heater 14 and the filter 104 is a channel with the same diameter and/or the same cross-sectional area for air flow.

In an embodiment, the heater 14 is in the form of a wire wrap, a flat piece, a ceramic piece, a single wire, a resistance wire mesh, or any other suitable shape that is configured to vaporize the finished vaporization composition 22. In at least one exemplary embodiment, heater 14 is made of any suitable electrically resistive material or materials. In another exemplary embodiment, heater 14 is a ceramic heater having an electrically resistive layer on its outer surface.

In an exemplary embodiment, the mouth end insert 8 of the first section 70 is permanently attached to the end of the first section 70, or alternatively the mouth end insert 8 is removable. In an exemplary embodiment in which the mouth end insert 8 is removable, this may ensure that the filter 104 can also be replaceable and/or refillable at the open end of the housing 6b, which is provided when the mouth end insert 8 is removed.

The position of the heater 14 is not limited to the position shown in FIG. 3, nor is the position of the filter 104 limited to the position shown in FIG. 3. For example, the heater 14 may be located at the downstream end of the outer air passage 9a, such that the heater 14 may be closer to the filter media housing 100. In an exemplary embodiment, the heater 14 may extend outward from the outer air passage 9a and inward a second outer passage 9b for air. In this case, the filter 104 can be installed closer to the insert 8 at the mouthpiece end or closer to the outer air passage 9a. In addition, the filter 104 may be located in the narrower outer air passage 9a either in place of the filter 104 located in the second outer air passage 9b or in addition to the filter 104 also located in the second air passage 9b. In an exemplary embodiment, the first section 70 contains more than one filter 104. In some embodiments, only the outer air passage 9b may be included without the air passage 9a, with the heater 14 and filter 104 in fluid communication via the air passage 9b .

In some exemplary embodiments, the heater 14 heats the filter media 100, but the heater 14 does not burn and/or ignite the filter 104 and/or the filter media 100. Thus, the filter media 100 in some exemplary embodiments is non-flammable. Because the first section 70 contains a heater 14 that vaporizes the finished vaporization composition 22, and the device 60 otherwise does not burn any material, the first section 70 and/or the device 60 may be referred to as a “non-combustible device.”

In an exemplary embodiment, power supply 94 is a battery, such as a lithium-ion battery. The battery may be a lithium-ion battery or one of its variants, such as a lithium-ion polymer battery. Alternatively, the battery is a nickel metal hydride battery, a nickel cadmium battery, a lithium manganese battery, a lithium cobalt battery, a fuel cell, or a solar photovoltaic cell. Any other power source or battery technology may be used. In an exemplary embodiment, the second section 72 may be configured to be used until the energy in the control system 1 power supply 94 is exhausted and/or falls below a set threshold. Alternatively, the power supply 94 of the control system 1 may be rechargeable and reusable and may include circuitry that allows the battery to be charged by an external charger, or may be rechargeable by solar energy. In some exemplary embodiments, the circuitry of the control system 1 in a charged state may supply power for a required (or alternatively specified) number of puffs until the energy in the power supply 94 is depleted and/or until the energy in the power supply 94 falls below a set threshold, after which the circuit must be reconnected to the external charger.

In an exemplary embodiment, the first section 70 is configured to connect to the second section 72 via a connection structure 75. In an embodiment, the connection structure 75 may have a threaded connection. A friction fit, snap connection, adhesive, removable and/or insertable pin, magnetic connection, or other suitable design may be used to attach the sections 70/72 to each other. Optionally, the second section 72 is permanently connected to the first section 70, such that the second section 72 may be a section integral with the first section 70. In an exemplary embodiment, device 60 does not have separate sections 70/72, thus device 60 represents one single section. Or alternatively, device 60 may comprise more than two sections. In an exemplary embodiment, section 70 or sections 70/72 together define an air flow path for device 60, with heater 14 and filter 104 in communication with this air flow path.

In some examples, the air flow passing through the device 60 may be caused by air being drawn into one or more air inlets 40 and through the first section 70. In the outer air passage 9a, the air flow may be entrained (released) by steam, which may be obtained as a result of heating by the heater 14 of the finished composition 22 for evaporation. In the second outer air passage 9b, heated steam 124 may pass through the filter housing 100 of the filter 104 to allow the steam to capture added flavor and/or nicotine from the filter housing 100 before the steam 124a is further downstream exiting the device 60. As mentioned, in some embodiments, only one air passage 9b may be present, and the steam produced by the heater 14 will flow directly into the air passage 9b, wherein the steam 124 may pass through the filter media housing 100 of the filter 104 to provide vapor capture flavoring and/or nicotine are added from filter housing 100 until steam 124a exits downstream from device 60.

In an exemplary embodiment, air flow passing through device 60 activates device 60. At least one sensor 92 may be configured to generate an output signal indicative of air flow, amount of air flow, and/or direction of air flow, wherein controller 90 may receive an output signal from at least one sensor 92 and determine the presence of the following internal conditions: (1) the direction of air flow indicates drawing air flow through device 60 (as opposed to blowing air through device 60) and/or (2) the amount of air flow exceeds the threshold value. In some example embodiments, only one condition may be sufficient to activate the heater, while in other examples, two or all conditions may need to be met before activating the heater. If these internal conditions of device 60 are met, controller 90 electrically couples power supply 94 to heater 14, thereby activating heater 14. In an exemplary embodiment, at least one sensor 92 generates a variable output signal that is at least partially related to the amount of pressure drop detected by at least one sensor 92. In an exemplary embodiment, the controller 90 may send a variable electrical current to the heater 14 based on a variable output signal from the at least one sensor 92. The at least one sensor 92 may include a sensor that is described in the application US Patent No. 14/793453 entitled "Electronic Smoke Apparatus", filed July 7, 2015, or the sensor which is described in US Patent 9072321 entitled "Electronic Smoke", issued July 7, 2015, each of which is included by references to this document in its entirety. Another type of sensor may be used to detect air flow.

In an exemplary embodiment, the filter 104 includes a second filter 122 0, which is a non-consumable filter (does not contain a sacrificial substance), which may be, for example, a cellulose acetate (CA) filter. A portion of the housing 103 and/or filter 104 may be coupled to the second filter 1220 by any known means and/or structure, including, but not limited to, an adhesive, coating, or housing 103 (e.g., tipping paper covering filter 1220 and filter 104, or a housing structure 103 that extends to cover both the filter 104 and the filter 1220, etc.), projections, pins, and the like. The second filter 1220 may be surrounded at least partially by a cover 1255, wherein the cover 1255 may be foil, lining paper, or other material to allow the downstream vapor 124a to pass through the second filter 1220 through at least the upstream and further along the flow is the end of the filter. As indicated, in some examples, cover 1255 may cover filter 1220, housing 103 may cover filter housing 100, and then both covers may be covered with an additional coating connecting them, or cover 1255 and housing 103 may be part of the same element. coating that covers both the filter 1220 and the filter housing material 100. In another example, the housing structure 103 may cover the filter housing material 100 and a separate coating may cover the filter 122 0 and the housing structure 103. Other options by which the filter 1220 are connected may be used. and a filter media housing 100. In an exemplary embodiment, the filter 104 and the second filter 1220 may be removed from the first section 7 4 of the device 62 as a single element, and a replacement filter 104 with filter 1220 may be inserted into the device 62. In another embodiment, the filter 104 is not connected to the second filter 1220, and instead the filter 104 is located at one end of the device 62, with the filter 104 being removable from the end of the device 62. In an exemplary embodiment, the filter 1220 takes the place of a mouthpiece end insert (such as insert 8 at the mouthpiece end according to FIG. 3), thus there is no separate insert at the mouthpiece end.

In an exemplary embodiment, dilution air (not shown) is introduced into the steam stream 124a downstream before the steam 124a exits the device 62. This can be achieved, for example, by perforating the sides of the cover 1255 of the second filter 1220.

In fig. 5 shows a diagram of another device 60a with a filter 104a that includes a reservoir 106, according to an exemplary embodiment. Reference numerals common to the previous embodiments are not described again here for the sake of brevity. In an exemplary embodiment, reservoir 106 holds nicotine, flavor, and/or a pre-formulated vaporizer. Reservoir 106 is in fluid communication with filter media housing 100 of filter 104a. Specifically, a wick system 132, such as a wick, capillary tube, narrow channel, or other structure capable of transferring nicotine, flavor, and/or vaporizer formulation from reservoir 106 to filter housing 100, is used to provide nicotine, flavor, and/or vaporizer. of the preformulated vaporizer onto the filter housing 100 during operation of the device 60a and/or is used to replenish the nicotine, flavor, and/or preformulated vaporizer in the filter housing 100 during operation of the device 60a.

In an exemplary embodiment, filter 104a and reservoir 106 are removable to allow reservoir 106 to be refilled once it is used up. In another embodiment, reservoir 106 is configured to be refilled without removing filter 104a and/or reservoir 106 from first section 70. In another embodiment, filter 104a, reservoir 106, and/or first section 70 are disposable, such that any or all of these elements can be disposed of after the contained filter media 100 and/or reservoir 106 are used up.

In another embodiment, instead of the separate dedicated reservoir 106 being in fluid communication with the filter media housing 100 of the filter 104a, the reservoir 20 within the first section 70 is in fluid communication with the filter media housing 100. In other words, in this In an embodiment, the reservoir 2 0 is in fluid communication with both the filter media housing 100 and the heater 14.

In fig. 6A illustrates a side view of a filter 404 in an insertion rod 406 according to an exemplary embodiment. In an exemplary embodiment, insert 406 includes at least three sections: a near-end section, which is a filter 404, a middle section 408, and a far-end section, which is a filter 410. The filter 410 in some exemplary embodiments is a non-consumable filter that does not contain a consumable (eg, filter 410 does not contain a consumable). The insert 406 has a blank-space-blank configuration in that the middle section 408 is primarily a section of open space (eg, wrapped in lining paper, which may also wrap around other sections). In some examples, the middle section 408 may include a flow restrictor 412. Flow restrictor 412 may be in the form of a thick-walled tube 412a, with the inner surface 412b of the tube walls defining a restricted flow passage of limited diameter 422. In this embodiment, filter 404 includes a filter media housing 100 formed from filter material 105 as described above. . In an exemplary embodiment, the middle section 408 defines open spaces 414/416 located on two sides of the flow restrictor 412 such that the flow restrictor 412 does not reach the ends of the middle section 408. In some examples, the flow restrictor 412 may extend to both ends of the middle section 408 or may reach one end rather than both ends of the middle section 408. The reduced inner diameter 422 of the flow restrictor 412 reduces the cross-sectional area of the air flow passing through the middle section 408 to control the RTD and the air flow passing through the rod 406. The non-consumable filter 410 is a filter that which may be, for example, a cellulose acetate (CA) filter. In an exemplary embodiment, filter 410 (or other filters described in various embodiments) may also contain nicotine, flavorings, and the like. In some embodiments, flavor beads and/or pressure burst beads may be contained in one or more sections. In an exemplary embodiment, the air flow passing through the insert 406 flows in a direction in which the air flow enters and flows through the housing filter material 100 before passing through the middle section 408 and the non-consumable filter 410. In some examples, the insert 406 may also contain less than three sections or more than two sections. For example, one example may contain a filter section and filter 104 as described, or another example may contain sections such as the middle section 4 08 and filter 104, and in other examples, three sections with additional spaces may thus be contained. , sections such as middle section 408, filter sections, and/or filter sections 104.

In an exemplary embodiment, insert 406 includes a housing structure 103 that spans the length of rod 406 by covering the outer surfaces of filter 404, middle section 408, and non-consumable filter 410 and/or any other sections that may form part of insert 406. In an exemplary embodiment only the containing structure 103 is wrapped around the matrix 100, the middle section 408, the filter section 410 and/or any other sections that may form part of the insert 406, other than that there is no other wrap around each of the sections that form a part of the insert 406 (then there are sections wrapped with only one wrapper, such as the containing structure 103, and connected therethrough). In an exemplary embodiment, the housing structure 103 is made of tipping paper. In another embodiment, the ends 406a of the insert 406 are made from any of the materials for the housing structure 103 according to the exemplary embodiments described herein. In an exemplary embodiment, the ends 406a of the insert 406 are open (eg, the housing 103 is wrapped only around the insert 406 in the longitudinal direction, thus the housing 103 is not present at the ends 406a of the rod 406). In another embodiment, the housing structure 103 is present at the ends 406a of the rod 406 and is made of any of the materials described in connection with the housing structure 103 included in the embodiments of this document. It should be understood that insert 406 with filter 404, middle section 408, and non-consumable filter section 410 collectively may be considered a filter.
