Description

Technical Field

[0001] The utility model relates to the technical field of heat-without-combustion atomization, in particular to an aerosol generating device and an aerosol generating system. Background Art

[0002] The heat-not-burn aerosol generating device (hereinafter referred to as HNB) is a device that heats the aerosol generating matrix to about 200-350°C in a heat-not-burn manner to generate an aerosol for the user to inhale. Since HNB generates aerosols by heating but not burning the aerosol generating matrix, there is no high-temperature combustion (the maximum temperature can reach 900°C), which avoids the process of high-temperature cracking and releasing harmful components. Therefore, the content of nicotine and other harmful substances in the aerosol generated by HNB is much lower than that of traditional aerosol generating matrices, which makes HNB a potential direction for the development of the aerosol generating matrix industry in the future.

[0003] HNB needs to use the heating element to heat the aerosol generating matrix that matches it. However, for the current aerosol generating device with a needle-type heating element structure, due to the high temperature of the heating element, the aerosol generating matrix enters the cold air from the bottom, and generates convection with the high-temperature airflow near the heating section of the aerosol generating matrix, thereby generating a large amount of condensation. The condensation liquid easily contaminates the device and the heating element, making it difficult to clean. Utility Model Content

[0032] In order to have a clearer understanding of the technical features, purposes and effects of the present utility model, the specific implementation methods of the present utility model are now described in detail with reference to the accompanying drawings.

[0033] The terms "connected" and "connected" used herein may mean directly connected or indirectly connected; "plurality" means two or more. "First" and "second" are only used to distinguish different components and should not be understood as implying relative importance or the number of components.

[0034] Figure 1 The aerosol generating device 1 in the first embodiment of the utility model is shown (partial schematic diagram). The aerosol generating device 1 can be used to insert the aerosol generating substrate 2, and can perform low-temperature baking and heating on the aerosol generating substrate 2 inserted therein after power is turned on, so as to release the aerosol without burning. The aerosol generating device 1 can be roughly rectangular columnar, cylindrical, elliptical columnar, etc. The aerosol generating substrate 2 can be detachably inserted into the aerosol generating device 1, and is heated by the aerosol generating device 1 to generate an aerosol, and it is convenient to take out the heated aerosol generating substrate 2 after heating is completed and replace it with a new aerosol generating substrate 2 for continued use. The aerosol generating substrate 2 can be roughly cylindrical, elliptical columnar, rectangular columnar, sheet-like, etc.

[0035] Combination Figure 2 and Figure 3 , the aerosol generating device 1 includes a heating element 10, a base 20 and a receiving seat 30. The receiving seat 30 and the heating element 10 are installed on the base 20, and the interior of the receiving seat 30 defines a receiving space 60 for accommodating the aerosol generating matrix 2, and the heating element 10 at least partially extends into the receiving space 60. The bottom end of the receiving space 60 is connected to a condensation chamber 70, and one end of the heating element 10 passes through the condensation chamber 70 and extends into the receiving space 60, which is used to be inserted into the aerosol generating matrix 2 and heat the aerosol generating matrix 2 to generate an aerosol. Specifically, the heating element 10 can be an infrared needle-type heating element, which is arranged in a longitudinal direction, and heats the aerosol generating matrix 2 by generating infrared radiation energy and heat conduction. It should be understood that the heating element 10 can achieve the above-mentioned effects through existing technologies, such as resistance heating, electromagnetic heating, infrared heating, etc.

[0036] The receiving seat 30 can be installed on the base 20 so as to move back and forth along the axial direction of the heating element 10. In this embodiment, the receiving seat 30 is an extractor. The receiving space 60 defined by the receiving seat 30 is coaxially arranged with the heating element 10, which can ensure that the aerosol generating matrix 2 is heated uniformly in the circumferential direction during the heating process, thereby ensuring the taste of the inhalation.

[0037] It should be noted that the cross-section of the receiving seat 30 in the present embodiment is circular, and in some other optional embodiments, its cross-section can also be rectangular, elliptical, polygonal, etc., and its specific shape is adapted to the shape of the aerosol generating matrix 2.

[0038] Now, the end of the extractor away from the heating element 10 is defined as the top end or the upward direction, and the end close to the heating element 10 (the end opposite to the top end) is defined as the bottom end or the downward direction. Then, the condensation chamber 70 is formed at the bottom end of the receiving space 60. The top end of the heating element 10 extends from the bottom end of the receiving seat 30 to the receiving space 60 through the condensation chamber 70. When the aerosol generating substrate 2 is inserted into the receiving space 60, the position of the top end of the heating element 10 in the receiving space 60 enables the heating element 10 to heat the aerosol generating substrate in the aerosol generating substrate 2.

[0039] The receiving seat 30 is detachably connected to the base 20, and the condensation chamber 70 can be defined by the receiving seat 30 and the base 20, that is, the condensation chamber 70 is formed at the docking position between the receiving seat 30 and the base 20. The condensation chamber 70 can also be formed only on the base 20, or only on the receiving seat 30. It should be noted that the above-mentioned docking position is not limited to a directly connected position, and also includes a situation where it is relatively connected but not in contact.

[0040] In some embodiments, the receiving seat 30 is fixedly arranged at the top of the base 20, and a receiving space 60 for inserting the aerosol generating substrate 2 is formed inside the receiving seat 30. Alternatively, the receiving seat 30 is fixedly arranged at the top of the base 20, and a receiving space is formed inside the receiving seat 30, and an extractor is arranged in the receiving space, the receiving space 60 is formed inside the receiving seat 30 and / or the extractor, and the condensation chamber 70 is formed at the bottom of the receiving seat 30 or the extractor.

[0041] In some embodiments, at least part of the space of the condensation chamber 70 is located below the end surface of the receiving space 60, and the radial dimension of the portion of the condensation chamber 70 corresponding to the end surface of the receiving space 60 is smaller than the radial dimension of the receiving space 60. In this embodiment, the condensation chamber 70 is cylindrical, and its diameter is smaller than the diameter of the receiving space 60, so as to ensure that the aerosol generating substrate 2 is confined in the receiving space 60 when inserted into the receiving space 60, and does not move into the condensation chamber 70.

[0042] In some other optional embodiments, the condensation chamber 70 may be in other shapes such as columnar, hemispherical, conical, or other irregular shapes. In addition, part of the condensation chamber 70 may be arranged non-coaxially with the receiving space 60, or part of the condensation chamber 70 may be located above the end surface of the receiving space 60.

[0043] The formation of the condensation chamber 70 has multiple beneficial effects, including but not limited to:

[0044] First, the condensation chamber 70 is located at the bottom of the receiving space 60, so that the unheated airflow can be preheated in the condensation chamber 70 before entering the aerosol generating matrix 2 in the receiving space 60. The condensation chamber 70 can serve as a transition space for the external airflow to enter the receiving space 60, which can reduce the amount of condensate generated by the meeting of high and low temperature airflows, so that the amount of dirt deposited on the inner wall of the chamber of the aerosol generating device and the surface of the heating element 10 is reduced. Second, the condensate and ash stains and other foreign matter generated by the aerosol generating matrix 2 during the heating process can be temporarily contained in the condensation chamber 70, avoiding the contact between the foreign matter and the high temperature area, avoiding the dispersion of the foreign matter, reducing the contaminated area, improving the ease of cleaning of the aerosol generating device 1 and reducing the odor of the aerosol.

[0045] like Figure 3 As shown, the receiving seat 30 includes a first side wall 31 and a first bottom wall 32. The first bottom wall 32 is arranged at the bottom end of the first side wall 31. The first bottom wall 32 is penetrated by a first socket 321 for inserting the heating element 10. The top end of the heating element 10 extends into the receiving space 60 through the first socket 321 to heat the aerosol generating matrix 2 inserted into the receiving space 60.

[0046] In some embodiments, the aerosol generating device 1 further includes an easy-to-clean pot 40, which is disposed on the base 20 and at the bottom of the receiving seat 30. The base 20, the receiving seat 30 and the easy-to-clean pot 40 are detachably connected to facilitate disassembly and cleaning. It should be understood that in some other optional embodiments, the base 20, the receiving seat 30 and the easy-to-clean pot 40 can also be made as one piece by welding, integral molding, etc.

[0047] In this embodiment, the condensation chamber 70 is defined by the easy-to-clean pot 40. The easy-to-clean pot 40 is cylindrical and is disposed on the base 20. The easy-to-clean pot 40 includes a second side wall 41 and a second bottom wall 42. The second bottom wall 42 is penetrated by a second socket 421 for inserting the heating element 10. The top end of the heating element 10 extends from the second socket 421 through the condensation chamber 70 and the first socket 321 into the receiving space 60.

[0048] The easy-to-clean pot 40 is embedded in the base 20 and is interference-fitted with the base 20 to achieve relative fixation and detachability. Specifically, a third socket 21 is formed on the base 20, and the second side wall 41 of the easy-to-clean pot 40 is simultaneously inserted into the third socket 21 and the first socket 321, and its outer wall surface is adapted to the inner wall surface of the first socket 321 and the third socket 21, and is interference-fitted with the third socket 21. This ensures that the condensate generated by the aerosol generating matrix 2 in the receiving space 60 is accommodated in the condensation chamber 70.

[0049] In some embodiments, the outer diameter of the second side wall 41 matches the diameters of the first insertion opening 321 and the third insertion opening 21 , and the upper end surface of the second side wall 41 is flush with the inner wall surface of the bottom wall 222 of the receiving seat 30 .

[0050] The present embodiment produces multiple beneficial effects by providing the easy-to-clean pot 40, including but not limited to: first, the provision of the easy-to-clean pot 40 allows the condensate and foreign matters such as residue stains generated by the aerosol generating matrix 2 to be contained in the condensation chamber 70 defined by the easy-to-clean pot 40, thereby reducing the contamination area of ​​foreign matters such as condensate and residue stains, and improving the easy-to-clean degree of the aerosol generating device 1. Second, the detachable provision between the easy-to-clean pot 40 and the base 20 and the receiving seat 30 allows the easy-to-clean pot 40 to be disassembled and cleaned during the cleaning process, and the easy-to-clean pot 40 can also be replaced as a consumable to achieve the cleaning of the aerosol generating device 1, further improving the easy-to-clean degree of the aerosol generating device 1.

[0051] It should be understood that in some other alternative embodiments, the aerosol generating device 1 may not be provided with the easily cleanable pot 40. The first socket 321 of the receiving seat 30 and the third socket 21 of the base 20 together define a condensation chamber, so as to achieve the effect of the above-mentioned condensation chamber 70.

[0052] For another example Figure 2 and Figure 3 As shown, in some embodiments, the aerosol generating device 1 further includes a seal 80. The seal 80 is disposed between the receiving seat 30 and the base 20 and is used to seal the gap between the receiving seat 30 and the base 20, ensuring the uniqueness of the air flow channel, and further preventing external cold air from entering the receiving space 60 through other channels and causing the high and low temperature air flows to meet, generating condensate. In this embodiment, the seal 80 is an O-ring.

[0053] In some embodiments, the aerosol generating device 1 further includes a reflection structure. The reflection structure is disposed in the receiving space 60 and is used to reflect the radiant energy generated by the heating element 10, so as to improve the utilization rate of the energy generated by the heating element 10, reduce energy consumption, and improve the consistency of the抽吸口感.

[0054] Referring together Figure 4 , the reflection structure is correspondingly disposed with the heating element 10. In this embodiment, the reflection structure includes a reflection film 50. The reflection film 50 includes a reflection film matrix and a reflection layer disposed on the inner and / or outer surface of the reflection film matrix. The reflection film matrix includes at least two "J"-shaped structures, and the at least two "J"-shaped structures are connected end to end to form a cylindrical shape. During the heating process, the heating element 10 emits infrared radiant energy. Part of the radiant energy passes through the aerosol generating matrix 2 and reaches the inner wall surface of the receiving seat 30, and is then radially reflected back into the aerosol generating matrix 2 through the reflection film 50 to perform secondary radiant heating on the atomization medium in the aerosol generating matrix 2, reducing energy loss, being beneficial to improving the utilization rate of energy, and enhancing the consistency of the口感.

[0055] Specifically, the reflection film matrix is made of stainless steel, and the reflection layer is a silver-plated layer. In some other alternative embodiments, the reflection film matrix may also be made of aluminum alloy (6061 or 6063) or copper, and the inner surface is polished.

[0056] It should be noted that the term "抽吸口感" in the original text seems to be an incorrect or incomplete expression. I have translated it as "抽吸口感" for now, but it may need to be corrected according to the actual context. Also, the description about "提升口感一致性" could be made more precise in terms of language expression.In some other optional embodiments, the reflective film substrate can also be surrounded by at least one N-shaped, M-shaped, Z-shaped, S-shaped, U-shaped, X-shaped, C-shaped, I-shaped, spiral-shaped, rectangular or other special-shaped structures to be cylindrical. The reflective film 50 can also be annular, spiral, arc-shaped, or a film track including at least one bending portion formed by a strip extension or a combination of multiple strips. The reflective film 50 can also be arranged on the outer wall surface of the receiving seat 30, or embedded in the wall surface of the receiving seat 30. The reflective film 50 can also be omitted, and a reflective layer is sprayed on the inner wall surface or outer wall surface of the receiving seat 30, or by changing the material of the section corresponding to the receiving seat 30 and the heating element 10, so that it has the function of reflecting infrared radiation to achieve the above-mentioned effect. It should be understood that the setting position of the reflective film 50 (or the reflective layer sprayed on the receiving seat 30) includes but is not limited to the part corresponding to the heating element 10.

[0057] By setting the reflective film 50, this embodiment produces multiple beneficial effects, including but not limited to: First, it can improve the energy utilization rate of the heating element 10, improve the consistency of each puff and the stability of the aerosol generation amount. Second, the reflective film 50 can improve the temperature field distribution in the receiving space 60 by setting different shapes, improve the uniformity of the temperature field, avoid the phenomenon of inconsistent taste caused by the uneven temperature field, and reduce the amount of stains generated by the aerosol generating matrix 2. Third, by setting the reflective film 50 to improve the temperature field in the receiving space 60, the probability of high and low temperature airflows meeting in the aerosol generating matrix 2 can be reduced in a targeted manner, thereby reducing the generation of condensate. Fourth, the heating efficiency of the medium can be improved, the preheating time can be shortened, and the "quick smoke output" of the first puff can be guaranteed, and the amount of smoke in each subsequent puff can be guaranteed.

[0058] Figure 5 The aerosol generating device 1b in the second embodiment of the utility model is shown. The main differences between the aerosol generating device 1b and the first embodiment include:

[0059] The receiving seat 30b and the easy-to-clean pot 40b are fixedly arranged, the two form a whole, and are detachably connected to the base 20. While ensuring that the lower end of the receiving space 60b is connected to the condensation chamber 70b to reduce the amount of condensate generated, the number of parts of the aerosol generating device 1b is also reduced, making the assembly process more convenient. During the cleaning process, only the receiving seat 30b and the easy-to-clean pot 40b fixed as one body need to be disassembled. It can also be directly replaced as a consumable to reduce the cleaning process.

[0060] It should be understood that the above fixing arrangement includes but is not limited to: welding, integral molding, gluing, fixed connection by bolts and other connectors, etc. In this embodiment, the receiving seat 30b and the easy-to-clean pot 40b are integrally molded, that is, the condensation chamber 70b is formed in the receiving seat 30b.

[0061] Figure 6 The aerosol generating device 1c in the third embodiment of the utility model is shown. The main differences between the aerosol generating device 1c and the first embodiment include:

[0062] The easy-to-clean pot 40c is fixedly arranged with the base 20c, the two form a whole, and are detachably connected to the receiving seat 30c. The number of parts of the aerosol generating device 1c is also reduced, making the assembly process more convenient. When cleaning the aerosol generating device 1c, only the receiving seat 30c is removed and then the base 20c and the easy-to-clean pot 40c are fixedly formed to be cleaned.

[0063] It should be understood that the above fixing arrangement includes but is not limited to: welding, integral molding, gluing, fixed connection by bolts and other connectors, etc. In this embodiment, the base 20c and the easy-to-clean pot 40c are integrally molded, that is, the condensation chamber 70c is formed on the base 20c.

[0064] The utility model also constructs an aerosol generating system, which includes an aerosol generating substrate 2 and the aerosol generating device in the above embodiments. Now, the aerosol generating device 1 in the first embodiment is taken as an example for description. Figure 2 As shown, the aerosol generating substrate 2 is inserted into the receiving space 60 , and at least a portion of the condensation cavity 70 is located below the end surface of the aerosol generating substrate 2 .

[0065] It is understandable that the above embodiments only express the preferred implementation of the utility model, and the description is relatively specific and detailed, but it cannot be understood as limiting the scope of the patent of the utility model. It should be pointed out that for ordinary technicians in this field, without departing from the concept of the utility model, the above technical features can be freely combined, and several deformations and improvements can be made, which all belong to the protection scope of the utility model. Therefore, all equivalent changes and modifications made to the scope of the claims of the utility model should belong to the scope of the claims of the utility model.
