Description

Technical Field

[0001] The utility model relates to the technical field of aerosol generating devices, in particular to an aerosol generating device and an aerosol generating system which are convenient for cleaning stains. Background Art

[0002] HNB (Heat-Not-Burn) aerosol generating products generate aerosol by heating tobacco, reducing the harmful components produced by the cracking of tobacco during high-temperature combustion.

[0003] Traditional smoking articles such as cigarettes and cigars need to generate aerosol by burning tobacco during use, but the way of burning tobacco will produce many harmful components; therefore, under the demand of the market, attempts have been made to provide alternatives to these tobacco burning articles by producing products that release compounds without burning. Examples of such products are so-called heat-not-burn products, which release compounds by heating tobacco instead of burning it.

[0004] The HNB centrally heated aerosol generating device corresponding to the HNB type aerosol generating product is the mainstream in the current market because it is portable, easy to use, has no open flame and no smoke.

[0005] The HNB centrally heated aerosol generating device heats the aerosol generating product to a temperature that atomizes the tobacco but is not high enough to burn it, that is, it allows the tobacco to emit a flavor similar to real cigarettes without burning it. Since there is no open flame combustion, it can reduce 90% of harmful substances and has a low tar content, which better meets the needs of consumers.

[0006] However, the conventional aerosol generating device still has the following defects: after long-term use, a large amount of stains will appear inside the aerosol generating device, and it is inconvenient to clean, thereby affecting the quality of aerosol generated by the aerosol generating device and resulting in a poor user experience.

The terms such as "installation", "fitting", "connection" and "fixation" should be understood in a broad sense. For example, "connection" can be a fixed connection or a detachable connection; it can be a mechanical connection or an electrical connection; it can be a direct connection or an indirect connection through an intermediate medium; "fixation" can be bolt fixation, snap fixation or glue fixation; the terms "first" and "second" are only used for descriptive purposes and cannot be understood as indicating or implying relative importance or implicitly indicating the number of technical features indicated; thus, the features defined as "first" and "second" may explicitly or implicitly include one or more of such features; "multiple" means two or more; in addition, "and / or" includes any and all combinations of one or more related listed items; for ordinary technicians in this field, the specific meanings of the above terms in the utility model can be understood according to the specific circumstances.

[0055] In order to make the purpose, technical solutions and advantages of the utility model clearer, the present invention is described in detail below with reference to the accompanying drawings and specific embodiments.

[0056] In this embodiment, the specific shape, structure, size, etc. of the "aerosol generating device and aerosol generating system" are not limited, and those skilled in the art can selectively use any appropriate implementation method according to actual needs.

[0057] Figure 1 A three-dimensional exploded view of an aerosol generating system provided in an embodiment of the utility model.

[0058] Figure 2 This is a three-dimensional exploded view of an aerosol generating device provided in an embodiment of the utility model. Figure 3 This is a schematic structural diagram of the second tubular body provided in an embodiment of the utility model. Figure 4 A schematic cross-sectional view of a second tubular body provided in an embodiment of the utility model. Figure 5 This is a three-dimensional exploded view of the first tubular body, the second tubular body and the operating member provided in an embodiment of the utility model.

[0059] See also Figure 1-Figure 5 The aerosol generating device 100 includes: a first tubular body 1 and a second tubular body 2 .

[0060] The second tubular body 2 is used to accommodate at least part of the aerosol generating product; the proximal end 2001 of the second tubular body 2 in the axial direction 1001 has an opening 201 for allowing the aerosol generating product to be inserted, and the distal end 2002 arranged opposite to the proximal end 2001 has a base 202 for supporting the bottom of the aerosol generating product.

[0061] Specifically, the aerosol generating product is made of HNB (Heat-Not-Burn) tobacco. At least part of the aerosol generating product can be heated in the second tubular body 2 to generate aerosol for the user to inhale.

[0062] In addition, at least a portion of the second tubular body 2 is rotatably disposed in the first tubular body 1 , and when the second tubular body 2 is rotated to an unlocking position, the second tubular body 2 can be removed from the first tubular body 1 .

[0063] In one embodiment, the first tubular body 1 is snap-connected with the second tubular body 2, and at least a portion of the second tubular body 2 is located in the first tubular body 1, and when the second tubular body 2 is not rotated to the unlocked position, the second tubular body 2 is snap-connected with the first tubular body 1, and is locked, so that the second tubular body 2 cannot move along the axial direction of the first tubular body 1, and therefore the second tubular body 2 cannot be removed from the first tubular body 1. When the second tubular body 2 is rotated to the unlocked position, the snap connection between the second tubular body 2 and the first tubular body 1 is released, and the second tubular body 2 can move along the axial direction of the first tubular body 1, so that the second tubular body 2 can be removed from the first tubular body 1.

[0064] Furthermore, the axial direction of the second tubular body 2 is parallel to the axial direction of the first tubular body 1 , and the aerosol generating product can be inserted into the second tubular body 2 along the axial direction of the first tubular body 1 or the second tubular body 2 , and can be pulled out from the second tubular body 2 along the axial direction of the first tubular body 1 or the second tubular body 2 .

[0065] In one embodiment, the aerosol generating product is a product including a mouthpiece. When the aerosol generating product is engaged with the second tubular body 2, the mouthpiece is exposed outside the aerosol generating device for the user to hold in the mouth. The second tubular body 2 is snap-connected with the first tubular body 1 to prevent the user from dragging the second tubular body 2 with the aerosol generating product when holding the aerosol generating product, so that the second tubular body 2 moves axially relative to the first tubular body 1. During the process of heating the aerosol generating product by the aerosol generating device, if the second tubular body 2 moves axially relative to the first tubular body 1, it will not only affect the heating effect of the aerosol generating product, but also may pose a safety hazard.

[0066] In one embodiment, when the second tubular body 2 is snap-connected to the first tubular body 1 , it is possible to prevent the second tubular body 2 from falling off when the aerosol generating device is inverted.

[0067] It should be noted that the conventional aerosol generating device has only one non-detachable tubular body, and the aerosol generating product is inserted into the above-mentioned tubular body of the conventional aerosol generating device, so the stains formed by heating the aerosol generating product are generated inside the above-mentioned tubular body; while the aerosol generating device 100 provided in the present application has a detachable second tubular body 2, and the aerosol generating product is inserted into the second tubular body 2 of the aerosol generating device 100 provided in the present application, so the stains formed by heating the aerosol generating product are generated inside the second tubular body 2.

[0068] In combination with the above description, it can be seen that compared with traditional aerosol generating devices, the aerosol generating device 100 provided in the present application only needs to take out the second tubular body 2 that is at least partially contained in the first tubular body 1, and can clean the stains in the second tubular body 2 or replace the new second tubular body 2 to avoid the taste of the aerosol generated by the aerosol generating device being deteriorated due to the stains, thereby improving the user experience.

[0069] Figure 6 The embodiment of the utility model provides Figure 5 A partial enlarged view at point A. Figure 7 The embodiment of the utility model provides Figure 5 A partial enlarged view at point B. Figure 8 A schematic structural diagram of the first tubular body and the second tubular body connected to each other, and the first protrusion and the slot-related parts provided in an embodiment of the utility model. Fig. 9 A cross-sectional schematic diagram of an aerosol generating system provided in an embodiment of the utility model. Fig.10 The embodiment of the utility model provides Fig. 9 A partial enlargement of point C.

[0070] In some embodiments, Figure 1-Figure 4 as well as Figure 9-10 As shown, the aerosol generating device 100 further includes a main body component 3. The main body component 3 may include a power supply component and a control component 4.

[0071] The first tubular body 1 is a component of the main body component 3, and the main body component 3 further includes a housing 304. Thus, the second tubular body 2 can be completely accommodated in the main body component 3 and can also be removed from the main body component 3.

[0072] In addition, a first accommodating cavity 301 , a second accommodating cavity 302 and a third accommodating cavity 303 are defined in the main body component 3 ; the first tubular body 1 is fixed in the first accommodating cavity 301 .

[0073] The power supply component is accommodated in the second accommodating chamber 302 ; the control component 4 is accommodated in the third accommodating chamber 303 .

[0074] It is understandable that when the second tubular body 2 is snap-connected with the first tubular body 1, the snap-connected portion between the second tubular body 2 and the first tubular body 1 is located in the first accommodating cavity 301, that is, the snap-connected position between the second tubular body 2 and the first tubular body 1 is hidden in the shell 304 to prevent the locked state of the second tubular body 2 from being accidentally released in an unexpected situation. Moreover, since the aerosol generating article can be heated in the second tubular body 2, the second tubular body 2 has a relatively high temperature, and the snap-connected position between the second tubular body 2 and the first tubular body 1 is hidden in the shell 304 to prevent the user from being scalded.

[0075] Specifically, the power supply component may include a rechargeable battery; wherein the main component 3 may be provided with: a Type-C charging interface 1003; the Type-C charging interface 1003 is connected to the rechargeable battery to charge the rechargeable battery. Of course, the power supply component may also include a disposable battery.

[0076] In some embodiments, in combination Figure 1-Figure 4 It can be seen that the aerosol generating device 100 further includes: an end cap 6 .

[0077] In this embodiment, the end cap 6 is detachably connected to the main body component 3, for example, the housing 304, and when the end cap 6 is connected to the housing 304, the proximal end 2001 of the second tubular body 2 is shielded, so that the second tubular body 2 is hidden in the aerosol generating device 100, and the second tubular body 2 is prevented from scalding the user when the aerosol generating device 100 is working. When the end cap 6 is removed from the main body component 3, the second tubular body 2 hidden in the housing 304 is exposed, and the user can remove the second tubular body 2 from the main body component 3 by using corresponding tools or means.

[0078] It should be noted that the end cap 6 has an insertion hole 601 for inserting the aerosol generating product into the second tubular body 2. When connected to the housing 304, the insertion hole 601 is communicated with the second tubular body 2, and the insertion hole 601 and the second tubular body 2 may have a common central axis.

[0079] For further information, please refer to Figure 1-Figure 4 When the end cap 6 is connected to the housing 304 , it is detachably abutted against the proximal end 2001 of the second tubular body 2 , so that the end cap 6 can contact the second tubular body 2 .

[0080] Alternatively, when the end cap 6 is connected to the housing 304, the end cap 6 is spaced apart from the proximal end 2001 of the second tubular body 2 so that the end cap 6 cannot contact the second tubular body 2, which is beneficial for reducing heat dissipation of the second tubular body 2 and can also prevent the temperature of the end cap 6 from being too high.

[0081] In other embodiments, the position of the end cap relative to the main assembly can be changed, for example, the end cap can be slidably connected or rotatably connected to the main assembly, so that the second tubular body disposed inside the shell can be covered and hidden by sliding or rotating the end cap relative to the main assembly, or the second tubular body disposed inside the shell can be exposed, so that the user can remove the second tubular body from the main assembly by using corresponding tools or means. In this embodiment, the end cap can also have an insertion hole.

[0082] In some embodiments, in combination Figure 1-Figure 4 and Figure 9-10 It can be seen that the aerosol generating device 100 further includes: a heating component 5. The power supply component is electrically connected to the heating component 5, and is used to provide power for the heating component 5 to generate heat. The heating component 5 heats the aerosol generating product by generating heat, so that the aerosol generating product generates aerosol.

[0083] In one embodiment, the heating component 5 is a component of the main body component 3, including: a heating base 51 and a heating element 52, the heating element 52 is fixed on the heating base 51, and when the second tubular body 2 is retained in the main body component 3, at least a portion of the heating element 52 passes through the base 202 and is located in the second tubular body 2, so as to be inserted into the aerosol generating article when the aerosol generating article is at least partially contained in the second tubular body 2.

[0084] In this embodiment, the heating element 52 may include a resistance heating element for generating Joule heat, the heating element 52 may include an infrared radiation element for radiating infrared rays, and the heating element 52 may include a susceptor capable of generating heat in a changing magnetic field.

[0085] In this embodiment, the heating element 52 may be in a needle shape or a sheet shape.

[0086] In one embodiment, the heating assembly 5 includes a heating element 52, which is retained on the second tubular body 2, so that the heating element 52 can be removed from the main body assembly 3 along with the second tubular body 2 to clean or replace the heating element 52. For example, the heating element 52 is fixed on the base 202 and extends at least partially in the second tubular body 2 to be inserted into the aerosol generating article when the aerosol generating article is at least partially accommodated in the second tubular body 2; or, for example, the heating element 52 is fixed on the side wall of the second tubular body 2 to heat the aerosol generating article in the circumference of the aerosol generating article when the aerosol generating article is at least partially accommodated in the second tubular body 2; or, for example, the heating element 52 is made of metal and constitutes at least part of the side wall of the second tubular body 2; or, for example, the heating element 52 constitutes at least part of the base 202 of the second tubular body 2 or is arranged on the base 202. In this embodiment, the heating element 52 includes a susceptor capable of generating heat in a changing magnetic field.

[0087] In one embodiment, the heating component 5 includes a heating element 52, which is retained on the first tubular body 1, or at least a portion of the first tubular body 1 is made of the heating element 52. When the second tubular body 2 is retained in the main body component 3, at least part of the heat generated by the heating component 5 is transferred to the aerosol generating article through the second tubular body 2, thereby heating the aerosol generating article.

[0088] In the embodiment where the heating element 52 includes a susceptor, the main body assembly 3 further includes a magnetic field generator electrically connected to the power supply component, and the magnetic field generator is used to generate a changing magnetic field so that the susceptor can generate heat in the changing magnetic field.

[0089] Fig.11 The embodiment of the utility model provides Fig. 9 A partial enlarged view at point D.

[0090] In some embodiments, according to Figure 1-Figure 4 as well as Figure 9-11 It can be seen that the control component 4 includes: a PCB board 41 and a button body 42.

[0091] A touch switch 411 is disposed on the PCB board 41 ; the PCB board 41 is connected to the heating element 52 and the power supply component respectively.

[0092] In addition, a portion of the button body 42 extends out of the main body assembly 3; another portion of the button body 42 extends into the third accommodating cavity 303, and contacts or separates from the touch switch 411 to control the heating element 52 to heat the aerosol generating product accommodated in the second tubular body 2.

[0093] In some embodiments, when the aerosol-generating article is contained in the second tubular body 2 , the heating element 52 may be inserted into the interior of the aerosol-generating article to generate an aerosol by heating the aerosol-generating article.

[0094] In some embodiments, the first tubular body 1 comprises an insulated tube, the wall of which is made of an insulating material or has an insulating layer in its wall.

[0095] It should be noted that the thermal insulation layer includes a sealed air thermal insulation layer, a vacuum layer or an aerogel layer.

[0096] Specifically, the thermal insulation material refers to a material whose thermal conductivity is less than 100 W / (m·K) at 23°C and 50% relative humidity, preferably less than 40 W / (m·K) or less than 10 W / (m·K). For example, the thermal insulation material may be made of at least one of a PAEK material, a PI material or a PBI material, wherein the PAEK material includes PEEK, PEKK, PEKEKK or PEK material.

[0097] It can be understood that the above-mentioned heat insulation layer can be in a normal pressure state, a negative pressure state, or a vacuum state.

[0098] In one embodiment, if Figure 1-Figure 4 as well as Figure 9-10 As shown, the end cap 6 may also include a dust cover 7 and a cover base, the insertion hole 601 is opened on the cover base, the dust cover 7 is slidably connected or rotatably connected to the cover base, and the dust cover 7 covers the insertion hole 601 or exposes the insertion hole 601 by changing the relative position between the dust cover 7 and the cover base. As an example, the dust cover 7 may have a first magnetic member, and the cover base may have a second magnetic member, and the insertion hole 601 can remain covered by the dust cover 7 or remain exposed through the magnetic attraction force or magnetic repulsion force between the first magnetic member and the second magnetic member.

[0099] In one embodiment, the end cover 6 and the main body assembly 3 are detachably connected by magnetic attraction.

[0100] See also Figure 5 , Figure 7 and Figure 8 The first tubular body 1 and the second tubular body 2 are detachably connected, and when the second tubular body 2 is rotated to the unlocking position, the second tubular body 2 can be removed from the first tubular body 1. Based on this, in one embodiment, a slot 101 is provided on one of the first tubular body 1 and the second tubular body 2, and a first protrusion 203 is provided on the other.

[0101] The slot 101 includes a first slot 1011 and a second slot 1012 which are interconnected and cross-arranged, so that the slot 101 is roughly "L"-shaped, and the first slot 1011 extends to the proximal end 2001 of the corresponding tubular body.

[0102] In addition, during the assembly of the first tubular body 1 and the second tubular body 2, the first protrusion 203 moves along the slot 101, and after moving from the first groove 1011 to the second groove 1012, the first protrusion 203 is snap-connected with the edge of the second groove 1012, so that the first tubular body 1 and the second tubular body 2 are locked in the axial direction 1001.

[0103] In some embodiments, Figure 1 As shown, a second protrusion 205 is formed on the inner wall of the second tubular body 2 , and the second protrusion 205 is used to clamp the aerosol generating product contained in the second tubular body 2 .

[0104] Fig.12 A schematic cross-sectional view of the first tubular body, the second tubular body and the operating member connected to each other, and the second convex strip and the related parts of the guide portion provided in an embodiment of the utility model.

[0105] Combination Figure 1-Figure 12 It can be seen that the operating member 8 can cooperate with the second tubular body 2. When the two cooperate, the second tubular body 2 and the operating member 8 are linked, and a part of the operating member 8 is located outside the aerosol generating device for user operation. The user operates the operating member 8 to release the snap connection between the second tubular body 2 and the first tubular body 1, and can remove the second tubular body 2 from the main body assembly 3.

[0106] In some embodiments, according to Figure 1-Figure 12 It can be seen that the second tubular body 2 is provided with a buckle portion 206 and a guide portion 207 for guiding the operating member 8 to buckle with the buckle portion 206; the second protrusion 205 defines at least part of the boundary of the guide portion 207. More specifically, there can be a plurality of second protrusions 205 and they are arranged at intervals from each other, and a guide portion 207 is formed between two adjacent second protrusions 205, and the operating member 8 can pass between the two adjacent second protrusions 205 and then buckle with the buckle portion 206.
