Detailed Description
In order to facilitate an understanding of the invention, the invention is described in more detail below with reference to the accompanying drawings and detailed description.
One embodiment of the present invention provides an aerosol-generating device for heating, rather than burning, smokable material, such as a tobacco rod, to volatilize or release at least one component of the smokable material to form an aerosol for smoking.
In a preferred embodiment, the aerosol-generating device heats the smokable material by radiating far infrared radiation having a heating effect; for example 3 to 15 μm, when the wavelength of the infrared light matches the wavelength of absorption of the volatile components of the smokable material, in use, the energy of the infrared light is readily absorbed by the smokable material, and the smokable material is heated to volatilise at least one of the volatile components to produce an aerosol for smoking.
As shown in fig. 1, the configuration of the gas mist generating device according to an embodiment of the present invention is such that the entire outer shape of the device is substantially configured as a flat tube, and the outer member of the gas mist generating device includes:
a housing 10 having a hollow structure therein to form an assembly space for necessary functional components such as infrared radiation; housing 10 has a proximal end 110 and a distal end 120 opposite along its length; wherein the content of the first and second substances,
the proximal end 110 is provided with a receiving aperture 111 through which the smokable material A may be received in the housing 10 to be heated or removed from the housing 10.
In order to achieve heating of the smokable material A received in the housing 10 by means of radiating infrared light, there is further provided within the housing 10 an infrared emitter 20 for heating, the configuration of one embodiment of which may be seen in figures 2 to 3, comprising:
a chamber 30 for receiving smokable material a is provided within the housing 10;
the infrared emitter 20 includes a first infrared emitter 21 disposed around the chamber 30, and a second infrared emitter 22; specifically, according to the structure shown in the figure, the structure and content of the first infrared emitter 21 and the second infrared emitter 22 are identical, and each of them includes two parts:
the base portion 211/221, which is a rigid supporting substrate material, may be made of high temperature resistant and infrared transparent material such as quartz glass, ceramic or mica;
an infrared-emitting coating 212/222, an infrared-emitting coating 212/222, which is formed on the base portion 211/221, is capable of causing itself to generate heat when energized and radiates infrared rays having a wavelength usable for heating the smokable material a, for example, the above 3 μm to 15 μm of far infrared rays. When the wavelength of the infrared light matches the wavelength of absorption of the volatile components of the smokable material a, the energy of the infrared light is readily absorbed by the smokable material a.
Typical implementations mid IR emitting coating 212/222 may be a coating made of a ceramic based material such as zirconium, or Fe-Mn-Cu based, tungsten based, or transition metals and their oxides.
In a preferred embodiment, the ir-emitting coating 212/222 is preferably composed of oxides of at least one metal element of Mg, Al, Ti, Zr, Mn, Fe, Co, Ni, Cu, Cr, Zn, etc., which can radiate far infrared rays having heating effect when heated to a suitable temperature; the thickness of the coating layer can be controlled to be 30-50 mu m; the oxide of the above metal elements can be formed on the surface of the base portion 211/221 by spraying the oxide onto the surface of the base portion 211/221 by means of atmospheric plasma spraying and then curing.
The above first infrared emitter 21 and second infrared emitter 22 are configured in the shape of an arc in cross section in the drawing, so that it is relatively easy to form the infrared-emitting coatings 212/222 on their surfaces, respectively.
Further in a preferred implementation, the first and second infrared emitters 21, 22 may be independently powered or controlled so as to independently radiate infrared light to heat different portions of the smokable material a. In particular, in an alternative control mode, it is possible to activate the first infrared emitter 21 and the second infrared emitter 22 alternately, or to activate them simultaneously.
Further from the implementation of the heating state shown in fig. 2 to 4, the shape of the chamber 30 is a flat shape, in particular an oval shape in fig. 2, i.e. the dimension in the vertical direction r1 is smaller than the dimension in the horizontal direction r2, so that the first infrared emitter 21 and the second infrared emitter 22 have a relatively larger radiation area for the smokeable material a.
Further in a preferred implementation, the first infrared emitter 21 and the second infrared emitter 22 are separate from each other and are movable with respect to each other, as shown in particular in fig. 2 and 3:
in figure 2, the first and second ir emitters 21, 22 are in a first position in which the smokable material a is received within the chamber 30 and substantially retains its own shape, typically cylindrical with a circular cross-section according to the preparation of the product and the configuration with which the user is familiar;
relatively close together in the directions indicated by arrows R1 and R2 in fig. 2 by first infrared emitter 21 and second infrared emitter 22, respectively, in fig. 2, to a second position shown in fig. 3; in the second position, the first and second ir emitters 21, 22 respectively surround and squeeze the smokable material a so as to deform it, substantially into a column of elliptical cross-section as shown in figure 3; at this time, the first and second infrared emitters 21 and 22 are activated, and the distance of the radiated infrared rays from the center O inside the smokable material a is greatly reduced, so that the ability and efficiency of absorbing infrared rays inside the smokable material a can be improved compared to the state in fig. 2, so that both the surface layer and the inside of the smokable material a can be heated relatively uniformly.
To facilitate the relative movement operation of the first and second ir emitters 21, 22, in the preferred embodiment shown in fig. 2 and 3, a first spring 41 and a second spring 42 are also provided within the housing 10, which when stretched in fig. 3 provide a resilient return force to bias the first and second ir emitters 21, 22 toward the first position shown in fig. 2, thereby facilitating removal of the smokable material a after smoking is complete.
Of course, in an alternative implementation, in order to stably hold the first infrared emitter 21 and the second infrared emitter 22 at different positions, a holding mechanism, such as the first holding element 51 shown in fig. 4 on the first infrared emitter 21, for example, a mechanical connection mechanism such as a magnet, a snap, etc., may be further provided in the housing 10; and a second holding element 52 which can be positioned on the second infrared emitter 22 and can cooperate with the first holding element 51 to form a fixing or connection, so that it is held in different positions.
In yet another variant implementation, as shown in fig. 5, the ir-emitting coating 212a of the first ir-emitter 21a is formed on an outer surface facing away from the chamber 30, or is an ir-emitting thin film, such as a zinc oxide thin film, a graphene thin film, a rare earth metal doped indium oxide thin film, or the like, wrapped around the outer surface of the first ir-emitter 21a facing away from the chamber 30. Meanwhile, in order to facilitate the power supply of the infrared emission coating 212a and enable the infrared emission coating to radiate infrared rays, a first conductive coating 213a and a second conductive coating 214a, which have excellent conductive properties such as silver, gold, or copper, are formed at the upper and lower ends of the outer surface of the first infrared emitter 21a, respectively; and then connected with a power supply device by welding a lead wire or sleeving a conductive ring and the like so as to supply power to the infrared emission coating 212 a.
Further in a variant implementation, the configuration of the infrared emitter 20b can be seen in fig. 6, comprising:
a first infrared emitter 21b and a second infrared emitter 22b configured in a sheet shape; and the first and second infrared emitters 21b and 22b are arranged on opposite sides of the chamber 30 b; and are relatively movable to compress the smokable material a received in the chamber 30b so that the smokable material a is compressed into the oval shape of figure 3 to improve the efficiency of infrared penetration into the centre so that both the surface and the interior of the smokable material a can be heated relatively uniformly.
In yet another alternative embodiment, as shown in figure 7, the smokable material a is configured in the form of a square block or sheet, which is different from the conventional cylindrical shape, and the first and second infrared emitters 21c and 22c of the infrared emitter 20c are respectively arranged oppositely in the thickness direction of the smokable material a, which further enables the smokable material a in the form of a block fitted with the cavity 30c to have a larger surface area to promote infrared absorption efficiency, promote heating efficiency and enable the smokable material a to be heated relatively uniformly to the surface and interior thereof.
And with the above aerosol-generating device during inhalation, as indicated by arrows R3 in fig. 3, 4 or 7, outside air may enter the chamber 30/30c from both sides from the spacing between the first infrared emitter 21/21c and the second infrared emitter 22/22c, respectively, until inhaled through the smokable material a.
It should be noted that the preferred embodiments of the present invention are shown in the specification and the drawings, but the present invention is not limited to the embodiments described in the specification, and further, it will be apparent to those skilled in the art that modifications and changes can be made in the above description, and all such modifications and changes should fall within the protection scope of the appended claims.
