Detailed Description

For a clearer understanding of technical features, objects and effects of the present utility model, a detailed description of embodiments of the present utility model will be made with reference to the accompanying drawings.

It should be noted that the terms "first," "second," "third," and the like are merely used for convenience in describing the present technology and are not to be construed as indicating or implying a relative importance or implicitly indicating the number of technical features indicated, whereby features defining "first," "second," "third," etc. may explicitly or implicitly include one or more such features. The specific meaning of the above terms in the present utility model can be understood by those of ordinary skill in the art according to the specific circumstances.

As shown in fig. 1-3, a heated nonflammable article of an embodiment of the present utility model includes a package 4. A filter section 3, a cooling section 2 and an aerosol-generating substrate 1 are sequentially arranged in the package 4 along the axial direction. The aerosol-generating substrate 1 is in a solid state, i.e. a solid. The package 4 has a certain length, and the axial direction of the package 4 is understood to be the longitudinal direction thereof or the longitudinal direction in the use state; the direction perpendicular to the axial direction of the package 4 or in contact with the central axis of the axial direction of the package 4 is radial. The aerosol-generating substrate 1, the cooling section 2, the filter section 3 and the wrapper 4 may all be cylindrical, but are not limited to being cylindrical, square, or other regular or irregular shapes.

The aerosol-generating substrate 1 is mainly intended to release aerosol in a heated state, the aerosol overflows from the proximal lip end of the aerosol-generating substrate 1 to the cooling zone 2, the filter zone 3 being closer to the mouth end of the heated non-combustible product than the aerosol-generating substrate 1. Under the action of sucking by a user, the aerosol released from the aerosol generating substrate 1 sequentially flows through the cooling section 2 and the filtering section 3 for cooling and filtering, and then flows out from the nozzle end of the heated non-combustible product for sucking by the user.

In particular, the aerosol-generating substrate 1 comprises opposed proximal and distal labial ends. The end face of the proximal lip end of the aerosol-generating substrate 1 is formed with at least one radially extending ventilation groove 10. The ventilation groove 10 is recessed from the end face of the proximal lip end of the aerosol-generating substrate 1 in a direction close to the end face of the distal lip end thereof, as seen in the axial direction, and extends in the radial direction.

During the shaping process of the solid aerosol-generating substrate 1, the raw material is extruded into a mould to form a solid aerosol-generating substrate 1 having a relatively stable shape. Therefore, the shape matched with the ventilation groove 10 can be reserved on the die, namely, the aerosol-generating substrate 1 with the ventilation groove 10 on the end surface can be formed in the extrusion process, so that the process step of punching holes on the cooling section 2 can be omitted.

The package 4 is provided with a ventilation structure at a position corresponding to the ventilation groove 10. The ventilation structure may be a ventilation aperture 40, the ventilation aperture 40 being a macroscopic hole. For example, as shown in fig. 1 to 3, in the present embodiment, at least one vent hole 40 in one-to-one correspondence with at least one vent groove 10 is formed in the package. In other embodiments, the breathable structure may also be a breathable film structure, such as breathable paper, breathable cloth, breathable cotton, or other breathable fibrous structures, with the holes of the breathable film structure being micropores that are not visible to the naked eye.

For example, as shown in fig. 1 to 3, the package 4 is provided with at least one vent hole 40 communicating with the vent slot 10. In particular, the vent 40 may be reserved during the molding process of the package 4. That is, the number of ventilation grooves 10 is at least one, and the number of ventilation holes 40 is also at least one. When there are a plurality (at least two) of ventilation slots 10 and/or ventilation holes 40, the plurality of ventilation slots 10 are distributed at intervals along the circumferential direction of the aerosol-generating substrate 1 on the end face of the aerosol-generating substrate 1, and the plurality of ventilation holes 40 are distributed at intervals along the circumferential direction of the package 4 on the package 4. The ventilation grooves 10 and the ventilation holes 40 are communicated in one-to-one correspondence.

Further, when a plurality of ventilation slots 10 and/or ventilation holes 40 are provided, the plurality of ventilation slots 10 may be symmetrically distributed over the aerosol-generating substrate 1; similarly, the ventilation holes 40 may be symmetrically distributed in the package 4.

The material of the aerosol-generating substrate 1 may comprise one or more of aromatic plant fibres, tobacco plant fibres, but may also comprise flavourants, binders, polyols etc. Further, the aerosol-generating substrate 1 may be porous to facilitate release of the aerosol. That is, the aerosol-generating substrate 1 comprises a plurality of interconnected micro-pores formed by drying moisture from the raw material during the formation of the aerosol-generating substrate 1. The porosity of the micropores of the aerosol-generating substrate 1 is positively correlated with the particle size of the aerosol. Preferably, the porosity of the micropores of the aerosol-generating substrate 1 may be in the range 20% to 80%. The pore size of the aerosol-generating substrate 1 may be in the range 50nm (nanometers) to 20 μm (micrometers). After the aerosol generating substrate 1 is heated, the aerosol generated by heating can be released through micropores, so that the aerosols generated at different positions are mixed, the uniformity of the aerosol is better, the aerosol flows to the cooling section 2, the cooling section 2 can play a role in centralized storage and cooling of the aerosol, when a user sucks the aerosol in the cooling section 2, the aerosol in the cooling section 2 is sucked away, and the newly generated aerosol flows into the cooling section 2 again, so that the aerosol can be effectively prevented from directly flowing into the mouth of the user, the mouth scalding is avoided, and the taste of the aerosol is improved.

The venting grooves 10 are in fluid communication with the venting structure on the cooling section 2 and the package 4, respectively. The cooling section 2 is also in fluid communication with the filtering section 3. The fluid may be a gas, an aerosol or a mixture of gas and aerosol, etc., with fluid communication between the two components meaning that the fluid may flow between the two components, i.e. the gas, aerosol or mixture of gas and aerosol, etc., may flow between the package 4, the venting groove 10, the temperature reduction section 2, the filter section 3. Under the suction effect, outside air sequentially enters the ventilation structure on the package 4 and the ventilation groove 10 on the aerosol generating substrate 1, and during the heating process of the aerosol generating substrate 1, the aerosol released from the aerosol generating substrate 1 flows to the cooling section 2 under the suction effect and is mixed with air flowing in from the ventilation groove 10, and the process can dilute and cool the aerosol, and meanwhile, the flow of the aerosol is facilitated, and the suction resistance is reduced.

As shown in fig. 1 to 3, the ventilation groove 10 is formed on the end face of the proximal lip end of the aerosol-generating substrate 1, that is, the ventilation groove 10 is formed on the end face of the aerosol-generating substrate 1 closer to the cooling section 2. Therefore, under the suction effect, the ventilation groove 10 is relatively closer to the cooling section 2, and the outside air directly flows to the cooling section above after entering the ventilation groove 10 from the ventilation structure on the packaging piece 4, so that the air flow is smoother.

As described in the background art, the existing three-stage heating non-combustible product is usually manufactured by providing at least one vent hole on the cooling stage 2, so that external air can enter from the vent hole, thereby achieving the purposes of cooling and reducing the suction resistance. However, in the process of manufacturing the heated non-combustible product, a punching step is added correspondingly for each cooling section 2 manufactured, and the manufacturing process is complex. Correspondingly, the utility model realizes the air intake of the heating incombustible product through the ventilation groove 10 on the aerosol generating substrate 1 and the ventilation structure on the package 4, and the ventilation groove 10 and the ventilation structure are respectively formed in the forming process of the aerosol generating substrate 1 and the package 4, thereby omitting the step of punching the cooling sections 2 one by one, simplifying the process of heating the incombustible product, and improving the production efficiency of the heating incombustible product.

Further, the cross-sectional profile of the vent slot 10 may be a curve, a broken line, or a combination of a curve and a broken line. It should be noted that "cross section" and "longitudinal section" are merely a set of opposite concepts with respect to the vent groove 10 itself, and the direction in which the vent groove 10 extends, that is, the radial direction is the longitudinal direction of the vent groove 10, and the section of the vent groove 10 in its longitudinal direction is referred to as its longitudinal section; correspondingly, the direction perpendicular to the longitudinal direction of the ventilation groove 10, i.e. the lateral direction of the ventilation groove 10, and thus the cross section of the ventilation groove 10 refers to the cross section of the ventilation groove 10 in the axial direction of the aerosol-generating substrate 1. As shown in fig. 1 and 2, and fig. 4, the cross-sectional profile of the vent slot 10 in this embodiment is curved with one curved edge. As yet another example, shown in FIG. 5, the cross-sectional profile of vent slot 10 is rectangular with three straight edges. As yet another embodiment shown in FIG. 6, the cross-sectional profile of the vent slot 10 is V-shaped with two straight edges. As yet another example shown in FIG. 7, the cross-sectional profile of vent slot 10 is polygonal with eight straight edges. Of course, the cross-sectional profile of the vent slot 10 may be other regular or irregular shapes.

The shape of the vent holes 40 may correspond to the shape of the vent grooves 10. The shape of the vent holes 40 may be the same as or different from the shape of the vent grooves 10.

In the embodiment shown in fig. 1 to 3, the radial extension of the ventilation slot 10 is perpendicular to the central axis of the aerosol-generating substrate 1. The radial extension line of the vent groove 10 refers to the extension line of the vent groove 10 in the radial direction, and may be a center line of the vent groove 10 extending in the radial direction. However, in other embodiments, the radial extension of the ventilation channel 10 may not be perpendicular to the centre axis of the aerosol-generating substrate 1, but may form an acute angle with the centre axis of the aerosol-generating substrate 1, i.e. an angle of more than 0 ° and less than 90 ° with the centre axis of the aerosol-generating substrate 1.

In other embodiments, the proximal end face of the aerosol-generating substrate 1 is inclined away from the cooling section 2 such that the proximal end face of the aerosol-generating substrate 1 forms an acute angle with its central axis, whereby an inclined ventilation channel 10 is formed between the proximal end face of the aerosol-generating substrate 1 and the distal end face of the cooling section 2.

Further, the package 4 is paper. Specifically, the package 4 may be air-permeable fiber paper, air-impermeable fiber paper, cardboard, or the like, or may be partially air-permeable, partially air-impermeable fiber paper.

As shown in fig. 1 to 3, in the present embodiment, the aerosol-generating substrate 1 further comprises a first air passage hole 11, and the first air passage hole 11 is a through hole or a blind hole. When the first airway orifice 11 is a through-hole, the through-hole penetrates the end face of the proximal lip end and the end face of the distal lip end of the aerosol-generating substrate 1. When the first airway orifice 11 is a blind hole, the blind hole penetrates the end face of the proximal lip end of the aerosol-generating substrate 1, but does not penetrate the end face of the distal lip end thereof. The ventilation groove 10 communicates with the first air passage hole 11. That is, the ventilation groove 10 extends in the radial direction as seen in the radial direction, and its both ends communicate with the first air passage hole 11 and the ventilation structure on the package 4, respectively. The first airway orifice 11 is used for aerosol collection and delivery. Thereby, the outside air enters the ventilation holes 40 on the package 4, the ventilation slots 10 on the aerosol-generating substrate 1 and the first air passage holes 11; during the heating process of the aerosol-generating substrate 1, the aerosol released from the aerosol-generating substrate 1 is collected at the first air passage holes 11 and flows to the cooling section 2 after being mixed with the air flowing in at the air vent grooves 10, and the air flowing in at the air vent grooves 10 has the functions of diluting and cooling the aerosol, and meanwhile, the concentrated flow of the aerosol is facilitated, and the suction resistance is reduced.

The number of the first air passage holes 11 may be one or more, and the plurality means two or more. When the number of first air passage holes 11 is one, the first air passage holes 11 may be central air passage holes as shown in fig. 1 to 3, i.e. located in the center of the aerosol-generating substrate 1, but are not limited to central air passage holes, and the location of the central air passage holes is not limited to the center of the aerosol-generating substrate 1. When the number of the first airway holes 11 is plural, the plurality of first airway holes 11 may be uniformly distributed on the aerosol-generating substrate 1.

After the aerosol generating substrate 1 is heated, the aerosol generated by heating can enter the first air passage holes 11 through the micropores to be collected, so that the aerosols generated at different positions are mixed, the uniformity of the aerosols is better, the aerosols flow from the first air passage holes 11 to the cooling section 2, the cooling section 2 can play the roles of intensively storing and cooling the aerosols, when a user sucks the aerosols in the cooling section 2, after the aerosols in the cooling section 2 are sucked away, the newly generated aerosols can flow into the cooling section 2 again, and the aerosols can be effectively prevented from directly flowing into the mouth of the user, so that the mouth is prevented from being scalded.

The radial cross-sectional profile of the first gas passage hole 11 may be a curve, a broken line, or a combination of a curve and a broken line. When the radial cross-sectional profile of the first air passage hole 11 is curved, the radial cross-section of the first air passage hole 11 may be circular, elliptical, petal-shaped, or the like. When the radial cross-sectional profile of the first air passage hole 11 is polygonal, the radial cross-section of the first air passage hole 11 may be rectangular, diamond-shaped, triangular, or the like. As shown in fig. 8, in the present embodiment, the radial cross section of the first air passage hole 11 is circular. In another embodiment, as shown in fig. 9, the radial cross section of the first gas passage hole 11 is elliptical. In another embodiment, as shown in fig. 10, the radial cross section of the first gas passage hole 11 is rectangular. In another embodiment, as shown in fig. 11, the radial cross section of the first gas passage hole 11 is star-shaped. In another embodiment, as shown in fig. 12, the radial cross section of the first gas passage hole 11 is petal-shaped. Of course, the first airway aperture 11 may be other regular or irregular shapes.

The radial cross-sectional shape of the first gas passage holes 11 may be identical throughout, or may be different throughout. For example, the radial cross-section of the proximal lip end of the first airway hole 11 is circular, while the radial cross-section of the distal lip end is rectangular.

The radial dimension of the first gas passage hole 11 in the axial direction may take the following forms: the radial dimension increases gradually in the direction from the end face of the distal lip to the end face of the proximal lip of the aerosol-generating substrate 1; or the radial dimension gradually decreases in the direction from the end face of the distal lip to the end face of the proximal lip of the aerosol-generating substrate 1; or the radial dimension gradually decreases from the end face of the distal lip end of the aerosol-generating substrate 1 to the intermediate position of the aerosol-generating substrate 1, gradually increases from the intermediate position of the aerosol-generating substrate 1 to the end face of the proximal lip end of the aerosol-generating substrate 1, i.e. the first gas passage holes 11 are the positions of smallest radial dimension at the axially intermediate position of the aerosol-generating substrate 1, and the radial dimension of the first gas passage holes 11 at the end face of the distal lip end of the aerosol-generating substrate 1 is larger than the radial dimension thereof at the end face of the proximal lip end of the aerosol-generating substrate 1 is different, i.e. the radial dimension of the first gas passage holes 11 in the axial direction appears small-min-large or large-min-small.

As shown in fig. 1 to 3, in the present embodiment, the cooling section 2 is a solid member, which is a cylindrical structure having a cavity passing through axially. That is, the cavity in the cooling section 2 forms the second air passage hole 22 of the cooling section 2. The second air passage hole 22 communicates with the first air passage hole 11. The cooling section 2 may be a hollow structure, that is, the second air passage hole 22 may be located at the center of the cooling section 2, but the position of the second air passage hole 22 is not limited to the center of the cooling section 2.

The cool down section 2 serves to further collect the aerosol and the aerosol is further diluted and cooled down at the second air passage holes 22 so that the aerosol reaching the mouthpiece where the non-combustible product is heated has a suitable temperature. Thus, during heating of the aerosol-generating substrate 1, the aerosol released from the aerosol-generating substrate 1 gradually collects at the first air passage holes 11 and flows upwards after mixing with the air flowing in at the ventilation slot 10 at the second air passage holes 22 of the temperature reduction stage 2 and then flows towards the filter stage 3.

Or in other embodiments the cooling stage 2 may not be a solid part, the cooling stage 2 being a cavity formed by the aerosol-generating substrate 1 and the filter stage 3. The aerosol released from the aerosol-generating substrate 1 is gradually collected at the first air passage holes 11 and the upward flow is collected at the temperature reduction section 2 (cavity), in the process being mixed with the air flowing in at the aeration tank 10, and then flows to the filter section 3.

Similar to the first airway orifice 11, the radial cross-sectional profile of the second airway orifice 22 may also be curved, broken lines, or a combination of curved and broken lines. Of course, the second air passage hole 22 may have other regular or irregular shapes, and the radial cross-sectional shape of the first air passage hole 11 may be referred to for specific purposes, and will not be described herein.

Similarly to the first air passage hole 11, the radial sectional shape of the second air passage hole 22 may be identical everywhere or may be different everywhere in the axial direction. For example, the radial cross-section of the proximal lip of the second airway orifice 22 is circular, while the radial cross-section of the distal lip is rectangular.

Similarly to the first air passage hole 11, the radial dimension of the second air passage hole 22 may take the following forms: the radial dimension gradually increases along the direction from the end face of the far lip end to the end face of the near lip end of the cooling section 2; or the radial dimension gradually decreases along the direction from the end face of the distal lip end to the end face of the proximal lip end of the cooling section 2; or the radial dimension gradually decreases from the end face of the distal lip end of the cooling section 2 to the intermediate position of the cooling section 2, and gradually increases from the intermediate position of the cooling section 2 to the end face of the proximal lip end of the cooling section 2, that is, the second air passage hole 22 is the position where the radial dimension is smallest in the axial intermediate position of the cooling section 2, and the radial dimension of the second air passage hole 22 at the end face of the distal lip end of the cooling section 2 is larger than the radial dimension of the second air passage hole at the end face of the proximal lip end of the cooling section 2 is different, that is, the radial dimension of the second air passage hole 22 in the axial direction appears small-smallest-large or large-smallest-small.

As shown in fig. 13, an aerosol-generating system according to an embodiment of the utility model comprises the heated non-combustion article of any of the embodiments, and a heating appliance. The heating means is for heating the heated non-combustible product such that the heated non-combustible product generates and releases the aerosol at a certain temperature.

Further, the heating device comprises a housing 5, and the housing 5 is formed with a slot, and the slot is matched with the heating non-combustion product of any embodiment of the utility model, so that the heating non-combustion product is inserted therein. The heating non-combustion product is detachably inserted into the slot of the heating appliance. The heating appliance further includes a heat generating component (not shown) provided in the housing 5, a power supply component (not shown) mechanically and/or electrically connected to the heat generating component, and the like, and the heat generating component heats the heated non-combustible product inserted in the socket in an energized state so as to generate aerosol. When the heating non-combustible product is installed in the slot, the bottom surface of the heating non-combustible product is attached to the bottom surface of the slot, or a certain interval is reserved between the bottom surface of the heating non-combustible product and the bottom surface of the slot.

The ventilation structure is at least partially located outside the slot, that is, the ventilation structure can be located outside the slot entirely or partially located outside the slot, so that the ventilation structure is prevented from being completely shielded by the inner wall surface of the slot, and at least part of the ventilation structure can be smoothly exposed and communicated with the outside air. For example, as shown in fig. 13, the top end of the vent 40 is located above the opening of the slot.

It is noted that the package 4 comprises a proximal lip end (see upper end of the package 4 in fig. 1) remote from the aerosol-generating substrate 1 and a distal lip end (see lower end of the package 4 in fig. 1) close to the aerosol-generating substrate 1. The top end of the vent 40 refers to the end of the vent 40 that is relatively farther from the distal lip end of the package 4 (i.e., the upper end of the vent 40 in fig. 3); conversely, the bottom end of the vent 40 refers to the end of the vent 40 that is relatively closer to the distal lip end of the package 4 (i.e., the lower end of the vent 40 in fig. 3).

In the case where the heated non-combustible product is fitted into the slot and the distal lip end face of the package 4 thereof is fitted to the bottom face of the slot, the depth of the slot is smaller than the distance between the tip of the vent hole 40 and the distal lip end face of the package 4. The depth of the slot refers to the dimension of the slot in the axial direction.

Specifically, when the depth of the slot is just equal to the distance between the tip of the vent hole 40 and the distal lip end face of the package 4, after the heated nonflammable product is inserted in the slot, the vent hole 40 on the package 4 is just completely blocked by the slot wall face of the slot, and at this time, air intake is difficult. Therefore, the depth of the slot needs to be smaller than the distance between the top end of the vent hole 40 and the distal lip end face of the package 4, so that after the heated non-combustible product is inserted into the slot, the vent hole 40 on the package 4 is at least partially exposed above the slot, so that air can smoothly enter the vent hole 40 on the package 4. Preferably, as shown in fig. 4, in this embodiment, the depth of the slot is equal to the distance between the bottom end of the vent hole 40 and the distal lip end face of the package 4, that is, the bottom end of the vent hole 40 is just flush with the opening end face of the slot, and the vent hole 40 is fully exposed, so that air can smoothly enter the vent hole 40 and the vent groove 10.

It is to be understood that the above examples only represent preferred embodiments of the present utility model, which are described in more detail and are not to be construed as limiting the scope of the utility model; it should be noted that, for a person skilled in the art, the above technical features can be freely combined, and several variations and modifications can be made without departing from the scope of the utility model; therefore, all changes and modifications that come within the meaning and range of equivalency of the claims are to be embraced within their scope.
