Detailed Description
The embodiments described below by referring to the drawings are illustrative only and are not to be construed as limiting the invention.
An embodiment of the present invention provides an improved gas path aerosol generating device, the configuration of which is shown in fig. 1 to 3, comprising:
the main body portion 10 forms a main housing structure of the aerosol-generating device, and is internally provided for mounting necessary functional components such as a battery cell, a circuit board, and the like.
The receiving chamber 20 is formed by at least a portion of the internal wall structure of the body portion 10, which receiving chamber 20 in the embodiment shown in fig. 1 is of an elongated shape extending in a longitudinal direction and is configured for receiving smokable material a, such as cigarettes, and of course the receiving chamber 20 has an open structure, depending on conventional use, so that the smokable material a can be manipulated between being received in the receiving chamber 20 or being removed from the receiving chamber 20.
The heating element 30, which heating element 30 in the embodiment shown in fig. 1 is in the form of a needle, pin, or sheet-like configuration extending in the axial direction of the receiving chamber 20, the heating element 30 being capable of penetrating or extending into the smokable material a when received in the receiving chamber 20, thereby heating the interior of the smokable material a to form an aerosol for inhalation by a user.
In practice, the heating element 30 may be made of a resistive metal material, so that it may be heated by means of direct current power supply, or may be made of a magnetic metal material having a suitable permeability, so that it may be heated by induction heating under an alternating magnetic field.
Of course, in other variant implementations, the heating element 30 may also be tubular or cylindrical in shape, the heating element 30 being configured to be disposed around the periphery of the smokable material a when the smokable material a is received in the receiving cavity 20, thereby heating the periphery of the smokable material a to form an aerosol for inhalation by a user.
Based on the manipulation between the receipt of the smokable material a within the receiving chamber 20 or the removal from the receiving chamber 20, the aerosol generating device further comprises:
The extractor 40 is removably attachable to the body portion 10, the extractor 40 comprising a cylindrical portion 41, the interior of the cylindrical portion 41 being hollow to form a holding space 42 for holding the smokable material a, the cylindrical portion 41 being arranged coaxially with the holding chamber 20 and extending into the holding chamber 20 in use so that at least a portion of the smokable material a held in the holding space 42 is received in the holding chamber 20, and further in use, the smokable material a is carried out of the holding chamber 20 together by a removal operation of the extractor 40 with the body portion 10, as shown in figure 3.
In the embodiment shown in fig. 1 and 3, the cylindrical portion 41 of the extractor 40 is provided with perforations 43 through which the heating element 30 in the form of needles, pins, or sheets is inserted, so that the heating element 30 can extend through the perforations into the smokable material a held in the cylindrical portion 41 for heating.
In one embodiment, during the suction, the air flow path is as shown by arrow R1 in fig. 1, with the gap of the junction of the extractor 40 and the outer surface of the main body portion 10 as an inlet port into which external air enters, so that the external air enters from the gap of the junction of the outer surface to the open end of the accommodation chamber 20, then extends toward the inside of the accommodation chamber 20 in the axial direction at a gap between the inner wall of the accommodation chamber 20 and the outer wall of the cylindrical portion 41, enters the smokable material a from the perforations 43 through the cylindrical portion 41, and then carries the aerosol in the smokable material a out to be sucked by the user.
In still another embodiment, a plurality of air holes are provided on the outer wall of the cylindrical portion 41, including a first air hole 411, a second air hole 412, and a third air hole 413, which are sequentially provided in the axial direction of the cylindrical portion 41. The air flow for flowing in the axial direction between the inner wall of the accommodation chamber 20 and the outer wall of the cylindrical portion 41 can directly enter into the cylindrical portion 41 through the first air hole 411, the second air hole 412 and the third air hole 413, as indicated by an arrow R2 in fig. 1 and 2, thereby changing the manner in which the air flow enters the smokable material a, and adjusting the suction resistance during suction.
In the preferred embodiment shown in fig. 2, the apertures of the first air holes 411, the second air holes 412 and the third air holes 413 are different, so that the air flow rates through the first air holes 411, the second air holes 412 and the third air holes 413 are different. In the preferred embodiment shown in fig. 2, it can be seen that the apertures of the first air hole 411, the second air hole 412 and the third air hole 413 are gradually changed in a decreasing manner, the aperture of the first air hole 411 is larger than the aperture of the second air hole 412, and the aperture of the second air hole 412 is larger than the aperture of the third air hole 413. Therefore, the air flow passing through the first air hole 411, the second air hole 412 and the third air hole 413 can be automatically adjusted according to the change of the suction strength of the user in the suction process, so that the suction resistance in the suction process can be always kept in a relatively balanced range, and the suction experience of the user is improved.
In still another embodiment, the number of the first air holes 411, the second air holes 412 and the third air holes 413 may be respectively plural, such as two groups as shown in fig. 2, but are not symmetrically disposed along the circumferential direction of the cylindrical portion 41 in an arrangement manner, particularly, a schematic view of the extractor 40 in the direction of arrow P in fig. 1 is shown in fig. 3, it can be seen that the main body portion 10 includes a first outer side wall 110 and a second outer side wall 120 opposite to each other in the width direction, the distance L1 between the cylindrical portion 41 and the first outer side wall 110 is smaller than the distance L2 between the cylindrical portion 41 and the second outer side wall 120, and the two groups of the first air holes 411, the second air holes 412 and the third air holes 413 are disposed toward a position close to the first outer side wall 110 and further away from the second outer side wall 120. The heat radiation and exchange of the heat in the accommodating chamber 20 at the portion near the first outer side wall 110 can be promoted by the differential distribution of the air flow.
In one embodiment, a further heating element 30a adapted for electromagnetic induction heating is proposed, the construction of which is shown with reference to fig. 5 to 6, comprising a base 31a and 4 heat generating portions 32a extending from the base 31a in the axial direction of the receiving chamber 20, and the 4 heat generating portions 32a are arranged radially in the radial direction of the receiving chamber 20. In practice, the base 31a may be formed of the same material and formed with the heat generating portion 32a, and may have a plate or block shape extending in the width direction, which may facilitate the fixation and installation of the heating element 30a in the aerosol-generating device. Meanwhile, as shown in the top view of fig. 6, the thickness of the heating part 32a inwards along the radial direction of the accommodating cavity 20 is gradually reduced, so that the distribution of heat of the heating part 32a can be effectively regulated, and the inwards thermal mass along the radial direction of the accommodating cavity 20 is gradually reduced, thereby on one hand, the thermal contact area with the smokable material A can be increased, and on the other hand, each part contacted with the smokable material A can only be kept relatively uniform. And this configuration can allow the resistance to be reduced accordingly when the cigarette is inserted into the heating element, thereby facilitating the insertion or removal operation.
Of course, to facilitate the insertion of the heating element 30a into the smokable material A, the end of the heating element 30a opposite the base 31a is tapered, or pointed in shape.
In still another preferred embodiment, the heat generating portion 32a is made of a material suitable for electromagnetic induction type heat generation, such as nickel, nickel-iron alloy, silicon steel, permalloy, or the like. However, of the 4 heat generating parts 32a, at least one of them is made of a first material such as the first heat generating part 321a shown in fig. 6, and at least one of them is made of a second material having a permeability coefficient different from that of the first material such as the second heat generating part 322a shown in fig. 6, so that the first heat generating part 321a and the second heat generating part 322a can have different heat generating efficiencies in a magnetic field. In practice, the component of the portion of the smokable material a in contact with the heat generating portion 32a having a high heat generating temperature volatilizes relatively quickly and forms an aerosol therein. As time goes by, the temperature of the heat generating portion 32a having a low heat generating temperature also gradually increases. This causes at least one component of another portion of smokable material A to volatilize and form an aerosol therein. Thus, over time, a gradual heating of the smokable material A is provided which helps to cause aerosol to form and release relatively quickly from a portion of the smokable material A for inhalation by a user, and a time-dependent release of aerosol is provided so that other portions can continue to form and release aerosol after the aforementioned portion of smokable material A has stopped generating aerosol.
The number of the heating parts 32a based on the above may be changed in practice according to the specification and the volume of the smokable material a, and may be increased or decreased accordingly, for example, 5, 6, 8, etc., so that it can be adapted to have a more appropriate contact area with the smokable material a, thereby making the heating more sufficient.
The aerosol-generating device adapted to the heating element 30a of this embodiment is constructed such that, as shown in fig. 7, a housing chamber 20a having an open upper end is formed in the main body portion 10a for receiving and heating the smokable material a such as a cigarette, and the heating element 30a has a shape extending in the axial direction of the housing chamber 20a so as to be insertable into the smokable material a for heating the same when the smokable material a is received in the housing chamber 20 a.
In this embodiment shown in fig. 7, the body portion 10a is provided with a spiral coil 50a arranged around the accommodation chamber 20a and extending in the axial direction of the accommodation chamber 20a, the spiral coil 50a being for generating an alternating magnetic field when an alternating current is supplied from a power source, and the heating portion 32a of the heating element 30a includes a first section 323a and a second section 324a in the longitudinal direction during the arrangement, wherein the first section 323a is closer to the opening of the accommodation chamber 20 a. And in practice, the first section 323a is located within the space surrounded by the spiral coil 50a, and the second section 324a is located outside the space surrounded by the spiral coil 50a, so that the magnetic field generated by the spiral coil 50 penetrates the first section 323a of the heating portion 32a and avoids the second section 324a of the heating portion 32 a. The second section 324a of the heating portion 32a is heatable in use by conduction of heat from the first section 323a of the heating portion 32 a. Thus, when the smokable material a is in use in the holding chamber 20a, the portion closest to the opening is first heated by the heat emitted from the first section 323a to form an aerosol. Over time, the temperature of the second section 324a increases with heat conduction such that another portion of the smokable material a remote from the opening is heated by the heat emitted by the second section 324a to form an aerosol. Thus, a gradual heating of the smokable material a is provided over time.
Also, in a more preferred embodiment, the length of the first section 323a is greater than the length of the second section 324a, so that the heating element 32a as a whole has a more suitable heating temperature and efficiency in pumping.
Based on the need to monitor the temperature of the heating element 30a throughout the use of the aerosol-generating device to prevent overheating of the temperature resulting in scorching of the smokable material a, temperature sensors 60a are typically employed in conventional practice to abut against the surface of the heating element 30a to effect temperature monitoring of the heating element 30 a. Thereby adjusting the duty cycle of the alternating current output to the spiral coil 50a based on the monitoring of the temperature, thereby facilitating the control of the pumping process.
The construction, features and effects of the present invention have been described in detail with reference to the embodiments shown in the drawings, but the above description is only a preferred embodiment of the present invention, but the present invention is not limited to the embodiments shown in the drawings, all changes, or modifications to the teachings of the invention, which fall within the meaning and range of equivalents are intended to be embraced therein, are intended to be embraced therein.
