Implementation of the invention

As used herein, the term "smoking material" refers to materials that release fumes when heated, usually in the form of an aerosol. "Smoking material" includes any tobacco-containing material and may, for example, contain one or more tobaccos, tobacco derivatives, exploded tobacco, reconstituted tobacco, or tobacco substitutes. "Smoking material" may also contain other non-tobacco products, which, depending on the product, may or may not contain nicotine. The "smoking material" may be, for example, a solid, liquid, gel or waxy mass or the like. "Smoking material" may, for example, be a combination or mixture of materials.

A device is known which heats a smokable material to vaporize at least one component of the smokable material, typically to form an aerosol that can be inhaled without burning or burning the smokable material. Such a device is sometimes described as a "heating rather than burning" tobacco device or a "tobacco heating article" or "tobacco heating device" or the like. Similarly, there are also so-called electronic cigarettes, which usually vaporize the smokable material in the form of a nicotine-containing or non-nicotine-containing liquid. The smokable material may be in the form of, or be provided as part of, a cartridge or cassette or the like, which can be inserted into the device. A heater for heating and vaporizing the smoking material may be provided as a "permanent" part of the device, or as part of the smoking article, or as a consumable item that is discarded and replaced after use. A "smoking article" as used herein is a device or article or other component including or containing smokable material that is heated during use to vaporize the smokable material and optionally other components.

In FIG. 1 shows schematically, in longitudinal section, an example of a device 10 for heating a smokable material to vaporize at least one component of said smokable material, typically to form an inhalable aerosol without burning the smokable material. Device 10 in this example is typically an elongated cylinder with a circular cross section. The device 10 has a mouthpiece 11 with an opening 12.

Within the device 10, there is a power supply 20 and a control circuit 22 for powering and controlling the operation of the device 10, respectively. Power supply 20 may be a battery, which may or may not be rechargeable. Examples of suitable batteries include, for example, a lithium ion battery, a nickel battery (eg, a nickel cadmium battery), an alkaline battery, and/or the like. Alternatively, power source 20 may be any suitable chemical or electrical power source, including, for example, a capacitor. Inside the device 10 there is also an irradiation source 30 for irradiating the smoking material contained in the device 10. The device 10 also includes at least one optical component for controlling the radiation emitted during operation by the irradiation source 30. Said at least one radiation control optical component may be a mirror, a beam splitter, a collimator, or any other optical component that may allow radiation to be manipulated. In the example shown, there is a lens 32 for controlling the radiation emitted in operation by the radiation source 30 also contained in the device 10. Controlling the radiation with the lens 32 may include one or more radiation focusing and radiation direction/rejection operations. The device 10 additionally has a receiver 40 for receiving the smoking material 50 and for receiving radiation emitted during operation by the source 30 of irradiating radiation.

Radiation source 30 produces radiation that is used to heat the smoking material 50 contained in the receiver 40 during use. ultraviolet. Suitable radiation wavelengths include wavelengths from 150 nm to 1 mm. The radiation may be laser radiation. For example, the source 30 of irradiating radiation may include a laser diode 36 for generating laser radiation. The laser diode 36 may be located and mounted on the holder 38 of the laser.

The device 10 during operation heats the smoking material 50 embedded or located in the receiver 40 by means of radiation from the source 30 of irradiating radiation. The radiation of the source 30 of irradiating radiation is controlled, that is, focused and/or directed by the lens 32 to hit the smokable material 50. The radiation is absorbed by the smokable material 50, so that the smoking material 50 is heated and evaporated. The device 10 further comprises a transparent wall or window 65 located between the lens 32 and the receiver 40. The transparent window 65 allows radiation to pass through, but prevents or facilitates the prevention of material generated by heating the smoking material 50 from contaminating at least either the lens 32 or the radiation source 30, and preferably both devices. It should be noted that the transparent window 65 should at least be transparent only for the wavelength(s) of radiation emitted by the radiation source 30, and indeed transparent enough to allow enough radiation to pass through to heat the smoking material, and may be opaque or transparent to other wavelengths. It will be understood that the transparent window 65 merely functions as a protective window and does not function as a lens, which is performed by the lens 32. The transparent window 65 may be rigid or substantially rigid. Suitable materials for the transparent window 65 may be, for example, glass, of which several different types are suitable for a given application, or plastics, of which again several different types are suitable for a given application, such as a substantially rigid transparent film window. Transparent window 65 may, for example, have a thin film coating to provide a suitable level of radiation transmission. Antireflection coatings, for example, can increase the transmission of radiation through a window. In another example, self-cleaning coatings can provide continuous transmission of radiation through the window during periods of use. In yet another example, the transparent window 65 may be non-rigid and may be made from, for example, a non-rigid film or the like.

Various embodiments are possible to allow the smokable material to be inserted into and removed from the device 10. For example, the device 10 may have a sliding or hinged door (not shown) to allow access to the inside of the device. In another example, the device 10 may have a detachable housing, consisting of at least two parts; in the specific example shown in FIG. 1, there are two housing parts, a laser diode housing part 15 containing a lens 32, a laser diode 36, and a laser holder 38, and a battery/control housing part 16 containing a power supply 20 and a control circuit 22. In the specific example shown schematically in FIG. 1, the laser diode housing part 15 and the battery/control housing part 16 are designed to be opened to allow access to the receiver 40. This can be realized, for example, with a sliding device, whereby one part of the split housing can be moved away from the other part of the split housing. or, for example, by unscrewing one part of the split housing from another part of the housing. Prior to use, the user may open the split body parts and insert the smokable material 50 into the receptacle 40 and then close the split body parts. Similarly, after use, the user may remove the exhausted smoking material 50 from the receptacle 40. An example of this is shown schematically in FIG. 2, in which the battery/control housing portion 16 is slightly pulled away from the laser diode housing portion 15 to allow access to the receptacle 40 for loading and removing smoking material 50. The housing portions 15, 16 may be sealed at the separation of the housing portions to provide landing when the parts 15, 16 of the body 15, 16 are connected. Such a seal may be in the form of, for example, an O-ring or mating interfaces, or the like.

The device 10 has on its surface at least one hole 70 for air inlet into the device 10 during operation. In the example shown, the device 10 has 8 air inlets 70 arranged circumferentially around the device 10 and next to the smoking material receptacle 40 50. The device 10 further has airflow inlets 72 so that, during operation, incoming air can pass from the holes. 70 to allow air to enter through the airflow inlets 72 and through or through the receptacle 40. The device 10 further has airflow outlets 74 that are positioned such that air that has passed through or through the receptacle 40 can pass to the mouthpiece 11 and exit device 10 through the hole 12 of the mouthpiece 11.

In the example shown in FIG. 1, each of the airflow inlets 72 is formed as a hollow conduit that leads from the respective air inlets 70 into the device 10 to a receptacle 40. In operation, air enters the air inlets 70 and then through the air flow, and then enters or passes through the receptacle 40 to capture the vaporized material obtained by heating the smoking material 50. The air with the entrained vaporized material after passing through or through the receptacle 40 then passes into the outlet channels 74 of the air flow. A transparent wall or window 65 is positioned opposite the laser diode housing portion 15 to prevent air and vaporized material from penetrating into the laser diode housing portion 15 and around the irradiation source 30 and the lens 32. As shown in FIG. 3, which shows a side view of the laser diode body part 15, in this example, the airflow outlets 74 are in the form of arcuate channels through the laser diode body part 15 and are arranged around the longitudinal axis of the laser diode body part 15 with four airflow outlets 74 provided in this particular example. Preventing the entry of air with trapped vaporized material into the interior of the laser diode housing portion 15 keeps the material away from lens 32 and laser diode 36 and thus keeps lens 32 and laser diode 36 clean and free of contaminants, which is important to ensure long service life of device 10 and source. 30 irradiation radiation and optical components.

In one example, the air inlet or hole 70 is closed by a valve 76. The valve 76 selectively allows air to enter the device 10 during operation. In one example, valve 76 is a non-return rubber slotted valve that opens when the user inhales through mouthpiece 11 and ensures that air cannot otherwise enter device 10.

In some examples, smoking material 50 itself, as a separate element, can be inserted into and removed from receptacle 40 of device 10. In other examples, smokable material 50 may be inserted into and removed from receptacle 40 of device 10 as part of a separate article that can act as a carrier or holder of smokable material 50. In such a case, device 10 has internal retaining walls 42 that face each other. friend to limit the channel that receives a separate product with smokable material.

In FIG. 4 and 5 schematically, in perspective and in longitudinal section, respectively, show an example of an article 60, which is particularly suitable for use with an aerosol generating device with a source of irradiating radiation and which can act as a carrier or holder of smokable material. The device may be the device 10 described above with reference to FIG. 1-3, although other embodiments of the device are possible.

Article 60 as shown in FIG. 4 and 5 has or provides a holder 62 for smoking material. The holder 62 has at least one transparent wall or window 65 that transmits radiation from the radiation source 30 of the device 10 with which the article 60 is used. 62. The transparent wall 65 allows irradiating light to pass through the transparent wall 65 and to the smokable material 50. The transparent portion may be a small transparent window in an otherwise opaque wall, or, as shown in this example, may be a completely transparent wall 65. It should be noted that the transparent wall 65, at a minimum, must be transparent only for the wavelength(s) of radiation emitted by the radiation source 30 of the device 10 with which the product 60 is used, and, moreover, only sufficiently transparent to allow sufficient radiation to pass through for heating the smoking material, and may be opaque or transparent to other wavelengths. Suitable materials for the transparent wall or window 65 include, for example, glass, a number of types of which are suitable for this application, or plastics, of which a number of types are also suitable for this application.

The holder 62 has at least one wall 66 that is opaque to the device 10 emitted by the radiation source 30 with which the article 60 is used. located on one side of the smokable material 50, and an opaque wall 66 located on the opposite side of the smokable material 50. Depending on the shape of the chamber 68, there may be other walls. In this example, other walls, if any, such as side walls 67 and bottom wall 69 are also opaque. It should be noted that the rear opaque wall 66 should at least be opaque to the wavelength of the radiation source 30 of the irradiating radiation, and may be opaque or transparent to other wavelengths. Suitable materials for the opaque wall 66 include, for example, metal, some plastics, and the like.

In some examples, the opaque walls 66, 67, 69 ensure that the radiation from the radiation source 30 of the device 10 with which the product 60 is used does not pass through the components of the device 10 that are located behind the product 60 during operation, including, for example, the power supply 20 and electrical circuitry 22 for controlling device 10. Chamber 68 is open or has an opening on one side (upper side in FIG. 4) so that vaporized material generated by heating smoking material 50 can exit chamber 68 and be entrained by airflow passing through device 10 with which product 60 is used.

In one example, smokable material 50 is removably inserted into chamber 68, and the user may insert smokable material 50 into chamber 68 before using article 60 and remove exhausted smoking material from chamber 68 after using article 60. In another example, smoking material 50 may attached to the wall of the holder 62, for example, with glue or some other device; in the example shown, smoking material 50 is attached to rear wall 66 of holder 62. In one example, smoking material 50 is attached to transparent window 65. In one example, smoking material 50 is attached to transparent window 65 with at least one clip. In one example, smoking material 50 is attached to a transparent window 65 with the possibility of subsequent removal, for example, using at least one clip. For example, two such clips can be used. Each clip may, for example, be part of the transparent window 65 or be a separate component. In yet another example, smoking material 50 may be attached to a transparent window, for example, using a suitable adhesive. In this example, smoking material 50 is permanently attached to the window. Also in this example, after use, the user can remove both the article 60 and the exhausted smoking material from the device 10 as a whole and replace them with a new article 60 with fresh smoking material 50. The advantage of replacing the entire article 60 after the smoking material 50 is depleted is is that the transparent wall 65 of the new product 60 will be clean. The clear transparent wall 65 provides increased transmission of radiation through it compared to a wall that has been passed repeatedly into the material to be evaporated. Increasing the transmission increases the efficiency of the device 10 and, as a result, the device consumes less power when generating aerosol. This means that the device 10 can operate longer using a particular power source, or require a lower lifetime cost. Inserting a new article 60 each time the smokable material 50 is depleted also allows the user to more easily avoid contact with the smokable material 50.

In FIG. 6 is a schematic, longitudinal sectional view of another example of a device 110 for heating smoking material 150 to vaporize at least one component of said smoking material 150, typically to form an inhalable aerosol without burning smoking material 150. Device 110 shown in FIG. 6 is generally similar to the example device 10 discussed above with reference to FIG. 1-3, and corresponding parts are designated by the same reference numerals increased by 100. A detailed description of the same or corresponding parts is omitted here for brevity, it being understood that the above description is applicable to this example. Be that as it may, as shown in FIG. 6, the device 110 has a mouthpiece 111 with an opening 112 at one end, a power supply 120 and control circuitry 122, an irradiation source 130, and a lens 132. The irradiation source 130 in this example includes a laser diode 136 for generating laser radiation (although as noted above, in some cases, other radiation sources may be used to produce non-laser radiation). The laser diode 136 is located inside and is supported by the laser holder 138. Device 110 has a receptacle 140 for receiving smokable material 150 either as a separate article or as part of a separate article that can act as a carrier or holder for smokable material 150, again as described above. Transparent wall or window 165 separates smoking material 150 from laser diode 136 and lens 132. Transparent wall or window 165 may be attached to device 110 or may be part of a separate article that can act as a carrier or holder of smoking material 150 and which is inserted and removed from device 110 as a whole.

In the shown in FIG. 6 of device 110, power supply 120 and control circuitry 122 are typically located toward the proximal end or mouthpiece of device 110, and radiation source 130 is typically located toward the opposite, distal end. An air inlet 170 is provided at the distal end of the device 110. Multiple air inlets 170 may be provided. Incoming air entering the air inlet(s) passes through or through the receptacle 140 to capture the vaporized material produced by heating the smoking material 150. The entrained vaporized air, after passing through or through the receptacle 140, then enters one or more outlets. channels 174 air flow. The airflow outlets 174 direct airflow through or through the device 110 towards the mouthpiece 111. Similar to the example of the laser diode housing portion 15 discussed above, in particular with reference to FIG. 3, in this example device 110, airflow outlets 174 may be provided as arcuate channels through the laser diode housing portion 115 and the battery/control housing portion 116. The relatively long airflow path in this example of device 110 compared to the example shown in FIG. 1-3 allows the air stream to cool more before exiting device 110.
