Description

Technical Field

[0001] The utility model relates to the field of smoking articles of novel tobacco products, in particular to an aerosol generating device. Background Art

[0002] Heat-not-burn (HNB) cigarettes evaporate the nicotine and flavoring substances in the cigarette through high-temperature heating, which is then inhaled by consumers in the form of an aerosol, thus satisfying their nicotine needs. As an important new tobacco product, HNB cigarettes are gaining increasing acceptance among consumers and are a valuable supplement to traditional tobacco.

[0003] During the use of heat-not-burn cigarette products, some aerosol will be emitted through the mouthpiece at the far end of the cigarette and condensed into droplets in the aerosol generating device. Some tobacco and other atomized material residues will also fall into the aerosol generating device. In particular, these condensed liquids and residues will accumulate at the bottom of the holding cavity for holding cigarettes, making them difficult to clean.

[0004] In the prior art, to clean aerosol generating devices, they are typically designed to be detachable. Specifically, an extractor for holding cigarettes, located within the aerosol generating device, can be removed from the upper end of the aerosol generating device for cleaning. Furthermore, residue within the extractor can leak into the chamber within the aerosol generating device, necessitating the use of a cleaning tool inserted through the upper opening of the aerosol generating device to clean the interior of the aerosol generating device.

[0005] However, the aforementioned cleaning method of inserting a cleaning tool through the upper opening of the aerosol generating device is inconvenient to operate, and improper use of the cleaning tool may cause damage to the interior of the aerosol generating device (for example, it may damage the heating component). In addition, it may be necessary to invert the aerosol generating device to pour out any residue that may have accumulated inside the aerosol generating device. During this process, the residue may further contaminate other components within the aerosol generating device, expanding the area that needs to be cleaned. There may also be stubborn stains at the bottom of the chamber inside the aerosol generating device. The cleaning method of inserting a cleaning tool through the upper opening of the aerosol generating device carries the risk of failing to thoroughly clean the stubborn stains at the bottom of the chamber.

[0031] The following is an explanation of the implementation of the present invention by means of specific specific embodiments. Those skilled in the art can easily understand other advantages and effects of the present invention from the contents disclosed in this specification. Although the description of the present invention will be introduced in conjunction with the preferred embodiment, this does not mean that the features of this utility model are limited to this implementation. On the contrary, the purpose of introducing the utility model in conjunction with the implementation is to cover other options or modifications that may be extended based on the claims of the present invention. In order to provide an in-depth understanding of the present invention, the following description will contain many specific details. The present invention can also be implemented without using these details. In addition, in order to avoid confusion or blurring the focus of the present invention, some specific details will be omitted in the description. It should be noted that, in the absence of conflict, the embodiments of the present invention and the features in the embodiments can be combined with each other.

[0032] It should be noted that in this specification, similar reference numerals and letters denote similar items in the following drawings, and therefore, once an item is defined in one drawing, it does not need to be further defined or explained in subsequent drawings.

[0033] The terms “first”, “second”, etc. are only used for distinguishing descriptions and should not be understood as indicating or implying relative importance.

[0034] The term "aerosol-generating article" includes an aerosol-generating substrate, which is a material that can provide volatile components when heated. The aerosol-generating substrate can be solid or liquid. For example, a liquid aerosol-generating substrate can contain water, solvents, ethanol, plant extracts, and natural or artificial flavorings. The aerosol-generating substrate can also be a paste-like material, a pouch of porous material containing the aerosol-generating substrate, or loose tobacco mixed with a gelling agent or adhesive, which may contain common aerosolizing agents such as glycerol. Alternatively, the aerosol-generating substrate can include tobacco-containing materials or non-tobacco materials, or can contain both tobacco and non-tobacco materials. Non-tobacco materials, for example, are flavorings that can be volatilized by heating or not, and may or may not contain nicotine. Tobacco materials, for example, can include one or more of tobacco, tobacco derivatives, expanded tobacco, reconstituted tobacco, or tobacco substitutes. The aerosol-generating substrate also includes an aerosolizing agent, such as glycerol or propylene glycol. The aerosol-generating substrate can also include additional ingredients, such as nicotine or flavoring extracts. For the solid aerosol generating matrix, it can be formed into a cigarette cartridge or a cigarette stick structure to be contained in a smoking device, and further made into a heated cigarette, which also includes a tobacco matrix part and a filter part.

[0035] In order to make the purpose, technical solutions and advantages of the present invention more clear, the embodiments of the present invention will be described in further detail below with reference to the accompanying drawings.

[0036] After careful research into existing technologies, the inventors discovered that the existing cleaning method of inserting a cleaning tool through the upper opening of an aerosol generating device to clean the interior of the aerosol generating device can damage internal components of the aerosol generating device, provide incomplete cleaning of the internal chamber of the aerosol generating device, and have difficulty removing stubborn stains. The inventors sought to address these issues.

[0037] refer to Figure 1 、 Figure 2 and Figure 3 The utility model provides an aerosol generating device 1. The aerosol generating device 1 includes a main body 2, a accommodating chamber 3, an opening 5, a heating element 10 and a container 6. The accommodating chamber 3 is located inside the main body 2, and the accommodating chamber 3 can be used to accommodate an aerosol generating product 4. The container 6 can be connected to the bottom end of the accommodating chamber 3, and is used to receive the residue after heating the aerosol generating product 4, such as the residue and condensate generated by heating the aerosol generating product 4 during use. Specifically, the container 6 can be connected to the bottom end of the accommodating chamber 3, and the residue after heating the aerosol generating product 4 can all fall into the interior of the container 6 and will not leak out of the outside of the container 6.

[0038] The container 6 is detachably connected to the body 2. The body 2 is provided with an opening 5. The container 6 is laterally inserted into the body 2 or removed from the body 2 from the opening 5. Figure 1 , Figure 1 The container 6 is shown to be located inside the body 2 and connected to the body 2. Figure 2 , Figure 2 The container 6 is shown as being removed from the opening 5 of the body 2 and positioned outside the body 2. Figure 3 The horizontal direction x is perpendicular to the axial direction y of the aerosol generating device 1. The horizontal direction x can also be the width direction of the aerosol generating device 1. By arranging the container 6 to be inserted and removed laterally, disassembly is convenient and easy to operate. The disassembly process only affects the container 6 itself, without disassembling other components of the aerosol generating device 1. This will not affect other components within the aerosol generating device 1, resulting in high overall structural stability and space saving.

[0039] Using the above technical solution, the aerosol generating device 1 separately provides a container 6 to receive the residue left after the aerosol generating product 4 is heated in the accommodating chamber 3. The container 6 is configured to be detachably connected to the body 2 of the aerosol generating device 1, and the detachable connection is also achieved by a transverse embedding method. With this configuration, since the residue generated during use has all fallen into the interior of the container 6, there is essentially no risk of leakage, and the residue will no longer remain in the aerosol generating device 1. When cleaning is required, only the container 6 needs to be removed and cleaned. This process will not affect the internal components of the aerosol generating device 1, and there is basically no need to clean the interior of the aerosol generating device 1. The cleaning process of the above-mentioned aerosol generating device 1 is simple and convenient, and it can also ensure thorough cleaning.

[0040] In the above embodiment, the aerosol-generating article 4 can be, for example, a heat-not-burn cigarette, which can include a mouthpiece section (i.e., a filter rod near the mouth end of the cigarette), a cooling section, and an atomizing section. The cooling section can be hollow. The atomizing section can include a smokable material, which can include an atomizer, a flavoring agent, and a carrier. The atomizer can be, for example, a glycerin or propylene glycol atomizer, the flavoring agent can be, for example, a fragrance, and the carrier can be, for example, a tobacco material.

[0041] refer to Figure 5 Combined with Figure 6 、 Figure 3 、 Figure 4 The container 6 includes a base 61 and a recessed portion 62, and the recessed portion 62 is provided on the base 61. When the container 6 is located inside the aerosol generating device 1, the recessed portion 62 of the container 6 is recessed relative to the accommodating chamber 3. With such a configuration, the recessed portion 62 of the container 6 forms a space for accommodating residues, and the space is connected to the accommodating chamber 3, and can accommodate residues after heating the aerosol generating product 4 (for example, residues and condensed aerosol droplets generated and dropped when the aerosol generating product 4 is heated, or dust in the air). Accordingly, the residues can be accumulated in the recessed portion 62. By providing the recessed portion 62 to accommodate the residues, since the space inside the recessed portion 62 is large, a large amount of residues can be accommodated, and under normal use, the residues are not easy to leak out of the recessed portion 62. For subsequent cleaning, it is only necessary to clean the container 6, thereby simplifying the cleaning process.

[0042] Furthermore, the maximum volume of residue that the recessed portion 62 can accommodate can be designed based on the specific usage requirements of the aerosol generating device 1 and the set cleaning interval. For example, the longer the cleaning interval, the larger the recessed portion 62 can be designed to accommodate more residue and prevent the inconvenience caused by residue overflow during cleaning.

[0043] Further, continue to refer to Figure 5 , the recessed portion 62 is bowl-shaped. Specifically, the recessed portion 62 has a rounded corner structure. By designing the recessed portion 62 into a bowl-shaped structure with rounded corners, it is easier and more convenient to clean the recessed portion 62 after removing the recessed portion 62, and the rounded corner structure does not have a cleaning dead corner, which facilitates thorough cleaning of the recessed portion 62. Even if the user does not remove the recessed portion 62 from the main body 2, but chooses to insert a cleaning tool (such as a cotton swab or a brush) from the upper opening of the aerosol generating device 1 to clean the recessed portion 62, due to the rounded corner structure of the recessed portion 62, there is no cleaning dead corner, and it is easier to clean the stubborn stains that may exist in the recessed portion 62, which is conducive to thorough cleaning.

[0044] refer to Figure 5 Combined with Figure 4 、 Figure 6 The container 6 further includes a handle 63. The handle 63 is provided on the side wall 611 of the base, connected to the base 61 by a soft material, and is rotatable and deformable relative to the base 61. The soft material connecting the handle 63 and the base 61 facilitates rotation of the handle 63 to remove or insert the container 6 into the body 2. The soft material may be, for example, silicone.

[0045] refer to Figure 7 Combined with Figure 1 When the container 6 is located in the aerosol generating device 1, the handle 63 is parallel to the opening 5. With this arrangement, the handle 63 does not expose too much volume outside the aerosol generating device 1, avoiding the risk of the container 6 falling out of the aerosol generating device 1 due to accidental touching of the handle 63, and the overall appearance is more beautiful.

[0046] refer to Figure 8 During the process of removing the container 6 from the aerosol generating device 1, the handle 63 can be flipped over, for example, by being rotated to a position perpendicular to the opening 5. Since the connection between the handle 63 and the base 61 is made of soft material, the handle 63 can be easily rotated to a position perpendicular to the opening 5, making it easier for the user to apply force to remove the container 6 from the aerosol generating device 1.

[0047] refer to Figure 3 Combined with Figure 2 The aerosol generating device 1 further includes a receiving space 7, which is located within the body 2 and communicates with the bottom end of the receiving cavity 3. The receiving space 7 is used to accommodate a container 6. When the container 6 is inserted into the aerosol generating device 1, specifically into the receiving space 7, the container 6 can be engaged with the receiving space 7 to prevent the container 6 from automatically falling out of the receiving space 7 under normal circumstances, thereby ensuring the stability and reliability of the entire aerosol generating device 1.

[0048] Furthermore, the aerosol generating device 1 further comprises a lower support 8 for the accommodating chamber and a bottom support 9. The lower support 8 for the accommodating chamber is located in the body 2 and is used to support the accommodating chamber 3. The bottom support 9 is located in the body 2 and can support the accommodating chamber 6 when the accommodating chamber 6 is inserted into the accommodating space 7. The accommodating chamber lower support 8 and the bottom support 9 form an accommodating space 7. The lower support 8 for the accommodating chamber further comprises a lower end surface 81 of the support. Figure 5 The base 61 of the container 6 further includes an upper end surface 612. When the container 6 is inserted into the receiving space 7, the upper end surface 612 of the base and the lower end surface 81 of the bracket are matched in a concave-convex manner to achieve mutual engagement between the container 6 and the receiving space 7. The concave-convex matching can also make this engagement more secure.

[0049] refer to Figure 5 Combined with Figure 6 In the above embodiments, the base 61 of the container 6 further includes a protrusion 64. The protrusion 64 is provided on the base 61 and protrudes relative to the upper end surface 612 of the base. Specifically, the protrusion 64 forms a circle around the recess 62 on the base 61, and the protrusion 64 can be a protruding circle. During the process of removing the container 6, the residue after heating the aerosol generating product 4 in the recess 62 may shake on the inner wall of the recess 62. By providing the above-mentioned protrusion 64, the residue after heating the aerosol generating product 4 can be effectively prevented from overflowing when shaking on the inner wall of the recess 62, thereby avoiding causing greater pollution, and ensuring that the residue after heating the aerosol generating product 4 remains in the recess 62, making it easier to clean.

[0050] Furthermore, when the container 6 is inside the aerosol generating device 1, the protrusion 64 can also engage the container 6 with the interior of the aerosol generating device 1, preventing the container 6 from automatically detaching from the aerosol generating device 1 under normal circumstances. The protrusion 64 also includes an outer peripheral sidewall 641, which is an inclined surface inclined relative to the axial direction of the aerosol generating device 1. The inclined surface facilitates the user's application of force when inserting or removing the container 6 from the aerosol generating device 1, making assembly and disassembly more convenient.

[0051] Continue to refer Figure 5 The inclined surface includes a bottom end 642 and a top end 643. The bottom end 642 is the end of the inclined surface of the peripheral side wall 641 that contacts the base 61. The top end 643 is the end of the inclined surface of the peripheral side wall 641 that is farther away from the base 61 in the axial direction y than the bottom end 642 when the container 6 is located in the aerosol generating device 1. Figure 5 Combined with Figure 3, when the container 6 is located inside the aerosol generating device 1, the first direction m is the direction along the inclined surface from the bottom end 642 to the top end 643; the second direction n is the direction along the axial direction y of the aerosol generating device 1 from the container 6 to the accommodation cavity 3, which can also be referred to as the direction opposite to the insertion direction of the aerosol generating article 4. The included angle formed by the first direction m and the second direction n is an acute angle. With such a setting, the outer peripheral side wall 641 of the protrusion 64 gradually converges in the second direction n. During the process of disassembling and assembling the container 6, it can prevent the protrusion 64 from being turned outwards and damaged or falling off. Further, designing such an inclined surface can also make it easy for the container 6 to be inserted into the aerosol generating device 1 and be hermetically sealed with the corresponding position in the aerosol generating device 1.

[0052] Further, continuing to refer to Figure 5 , the height by which the protrusion 64 protrudes relative to the upper end surface 612 of the base is 0 < h ≤ 0.5 mm. Within this height range, it can not only prevent the difficulty in disassembly and assembly caused by excessive height, but also effectively prevent the container 6 from automatically falling off after being inserted into the aerosol generating device 1, so that the container 6 is stably fixed in the aerosol generating device 1, and can also avoid the residues after heating the aerosol generating article 4 in the recess 62 from shaking and overflowing to cause pollution.

[0053] Further, in each of the above embodiments, the entire container 6 can be made of a soft material. Specifically, the material of the entire container 6 can be silica gel, which has a certain heat resistance and can withstand a high temperature of about 300°C, for example, it can withstand a high temperature of 250 - 350°C. In addition, since the container 6 is inserted into the aerosol generating device 1, the container 6 is in close contact with the lower end surface 81 of the bracket of the accommodation cavity lower bracket 8, and the container 6 and the accommodation cavity lower bracket 8 form a tight connection, playing a sealing role. Using silica gel can further ensure the aging resistance of the container 6 and extend its service life.

[0054] Continuing to refer to Figure 3 , in the aerosol generating device 1, the heating element 10 is located inside the body 2 and is disposed outside the accommodation cavity 3 or defines the accommodation cavity 3. Where the heating element 10 defines the accommodation cavity 3, that is, at least a part of the heating element 10 forms at least a part of the accommodation cavity 3, that is, at least a part of the heating element 10 also serves as at least a part of the accommodation cavity 3. A circuit control system connected to the heating element 10 is also provided inside the aerosol generating device 1. When using the aerosol generating device 1, the circuit control system can continuously supply power to heat the heating element 10 so that the heating element 10 generates heat, and thus the heating element 10 can heat the aerosol generating article 4 located in the accommodation cavity 3 to generate aerosol for the user to inhale.

[0055] Furthermore, the heating element 10 is a hollow tubular structure. For example, the heating element 10 can be a heating tube, which can be an energized self-heating tube that directly heats the aerosol generating product 4, or the heating element 10 can be energized to generate heat and then indirectly heat the aerosol generating product 4 by heat conduction. The heating element 10 can be a resistive heating method or an electromagnetic heating method, and it is only necessary to perform external heating on the aerosol generating product 4. Among them, for the electromagnetic heating method, the sensor serves as the heating element 10, which defines the accommodating cavity 3. By setting the heating element 10 to perform external heating on the aerosol generating product 4, when residues (such as residues or condensate) are generated, these residues can all fall into the container 6 below the accommodating cavity 3 without contacting the heating element 10, thereby avoiding contamination of the heating element 10, reducing the number of parts that need to be cleaned, and simplifying the cleaning process.

[0056] The heating element 10 is made of a high-temperature resistant material, which can be metal, ceramic, or a tubular object made of other carbon-containing or silicon-containing materials. The heating element 10 made of a high-temperature resistant material can provide more stable and reliable heating, have a long service life, and high heating efficiency.

[0057] In the above embodiments, the lower bracket 8 of the accommodating chamber can also be used to support the heating element 10, fix and support the heating element 10, and prevent the heating element 10 from sliding out of the accommodating chamber 3. Figure 3 The aerosol generating device 1 may further include an upper housing bracket 11 for further securing and supporting the housing chamber 3 from above, thereby further stabilizing the position of the housing chamber 3. The upper housing bracket 11 may also be further configured to securely support the heating element 10 from above. By securing the heating element 10 to the housing chamber 3 from both ends through the upper housing bracket 11 and the lower housing bracket 8, the connection between the housing chamber 3, the heating element 10, and the aerosol generating device 1 is made more stable and reliable, preventing the housing chamber 3 and the heating element 10 from slipping into the receptacle 6 and contacting any residue therein.

[0058] Furthermore, both the upper and lower support brackets 11 and 8 of the accommodating cavity can be made of high-temperature resistant materials to prevent the heating element 10 from heating at excessive temperatures, thereby preventing deformation and other damage to the upper and lower support brackets 11 and 8. Preferably, the thermal conductivity of the material of the lower support bracket 8 is 0.05-5W / (m*K), and the thermal conductivity of the material of the upper and lower support brackets 11 is also 0.05-5W / (m*K). The materials of the upper and lower support brackets 11 and 8 can be polyetheretherketone, polyimide, nylon-based polymer materials, or inorganic materials such as ceramics.

[0059] In the above embodiment, the accommodating chamber 3 can be a cavity surrounded by the accommodating chamber lower bracket 8 and the heating element 10, and can further be a cavity surrounded by the accommodating chamber upper bracket 11, the accommodating chamber lower bracket 8 and the heating element 10.

[0060] After the aerosol-generating article 4 is inserted into the accommodating chamber 3, the bottom end of the aerosol-generating article 4 is abutted by the lower support 8 of the accommodating chamber, thereby preventing the bottom end of the aerosol-generating article 4 from entering the recess 62 of the container 6. During heating and use, if residue (e.g., residue or condensate) accumulates in the recess 62, if the bottom end of the aerosol-generating article 4 is located in the recess 62, the aerosol-generating article 4 may come into contact with the residue (e.g., residue or condensate). During inhalation, the aerosol may contain the flavor of the residue (e.g., residue or condensate), affecting the user's taste. With the above arrangement, after the aerosol-generating article 4 is inserted into the accommodating chamber 3, the bottom end of the aerosol-generating article 4 is abutted by the lower support 8 of the accommodating chamber, preventing the aerosol-generating article 4 from coming into contact with the residue (e.g., residue or condensate) in the recess 62. This allows for a purer aerosol to be produced during inhalation, ensuring a good taste for the user.

[0061] Further, continue to refer to Figure 3 The lower support 8 of the accommodating chamber further includes a sidewall 82 and a through hole 83. The through hole 83 is provided on the sidewall 82 and is located between the accommodating chamber 3 and the accommodating space 7. During the inhalation process, the external airflow from outside the aerosol generating device 1 can pass through the through hole 83 and enter the accommodating chamber 3 to mix with the smoke of the aerosol generating product 4. The external airflow does not pass through the recessed portion 62 and does not come into contact with the residue (such as residue or condensate) in the recessed portion 62, which helps to ensure the purity of the aerosol and improve the inhalation taste.

[0062] The aerosol generating device 1 in the above-mentioned embodiments of the present invention is provided with a separate container 6 to receive the residue after heating the aerosol generating product 4, and the container 6 is provided in a manner that is detachably connected to the aerosol generating device 1, and is also laterally embedded or detachable. Residues and condensate can all fall into the interior of the container 6 without leaking and adhering to other components in the aerosol generating device 1. When cleaning, only the container 6 needs to be cleaned, and the cleaning process is simple and convenient. In addition, by removing the container 6 for cleaning, it is beneficial to clean the container 6 more thoroughly, which can prevent stubborn stains from remaining in the container 6, thereby preventing the stains from affecting the taste of the inhaled aerosol. The present invention also improves the container 6 itself, and provides a recessed portion 62 for accommodating the residue as a concave bowl-shaped structure, forming rounded corners, which is beneficial to avoid cleaning dead corners and facilitates thorough cleaning. The present invention also provides a protrusion 64 on the container 6 to further prevent residual matter from overflowing from the container 6 and to achieve a stable and reliable engagement with the aerosol generating device 1, preventing the container 6 from abnormally falling off. The present invention also provides a lower support 8 for the receiving chamber to support the receiving chamber 3. The lower support 8 can also abut the bottom end of the aerosol generating product 4 after the aerosol generating product 4 is inserted, preventing the aerosol generating product 4 from coming into contact with any residual matter in the container 6, thus preventing the generated aerosol from changing its flavor, making the inhaled aerosol purer and ensuring a good inhalation experience for the user.
