The aerosol generation device is capable of heating, in a low temperature heating but not burning manner, anaerosol generation substrate 3 to generate smoke to be inhaled by users. It is appreciated that the aerosol generation device is not limited to the cylindrical form and can be of other shapes, such as a form of a square prism. In the embodiment, theaerosol generation substrate 3 is a rolled cigarette. - The extractor 1, in some embodiments, may comprise a
first housing 11 and a firstmagnetic body 13 in a form of a circular ring tightly embedded in a bottom of thefirst housing 11. Thefirst housing 11 has an inside wall surface that defines areceiving space 110 for receiving theaerosol generation substrate 3 therein. Thereceiving space 110 has an opening on its top, and thereceiving space 110 has a bottom that forms abottom wall 112. Thebottom wall 112 is formed with an insertion opening 111 into which theheater 22 is insertable. Theaerosol generation substrate 3 is insertable from the top opening of thereceiving space 110 into the interior of thereceiving space 110 and contacting thebottom wall 112. - The main body 2, in some embodiments, may comprise a
second housing 21, theheater 22, aseat 24, and a secondmagnetic body 23. Thesecond housing 21 has an interior in which electronic components, such as a battery and a circuit board, can be disposed for supplying electricity power to theheater 22 and controlling operations of activation and deactivation of the aerosol generation device. - The
seat 24 is fit, in the longitudinal direction, into an upper end of thesecond housing 21, and comprises asidewall 2411 which is cylindrical, and atop wall 2412 which is integrally formed with a top of thesidewall 2411 and in the form of a circular plate. Thesidewall 2411 is raised outwards from two sides thereof in a circumferential direction to each form asnap platform 2413, and an inner wall surface of thesecond housing 21 is recessed to formsnap troughs 211 respectively corresponding to thesnap platforms 2413. Thesnap platforms 2413 and thesnap troughs 211 are mutually snap engageable with each other, therefore theseat 24 is fixed in a snap manner in the interior of thesecond housing 21. The fixing between theseat 24 and thesecond housing 21 that is achieved with insertion and internal snap engagement is easy and reliable and makes no exposure of any external engagement outside the main body 2, so as to be more aesthetically pleasing. The secondmagnetic body 23 is in a form of a circular ring, which is tightly embedded inside thesidewall 2411 and abutting against a lower end face of theseat 24. The firstmagnetic body 13 and the secondmagnetic body 23 are magnets that attract each other, or can be any other elements that exhibit magnetic properties (such as iron-cobalt- nickel). - The
heater 22 is fit, in the longitudinal direction, into thetop wall 2412 and comprises aheating section 221 that extends into thereceiving space 110 to heat theaerosol generation substrate 3. Theheating section 221 is extended through the insertion opening 111 in the bottom of thereceiving space 110 into thereceiving space 110 and inserted into theaerosol generation substrate 3 in order to heat and bake theaerosol generation substrate 3. Theheater 22 can be in a form of a plate or a bar. An upper end of theheater 22 is provided with a sharpened guide structure to facilitate insertion into theaerosol generation substrate 3. A shape of theinsertion opening 111 can correspond to a cross-sectional shape of theheating section 221, and a cross-sectional size of theinsertion opening 111 can be slightly greater than a cross-sectional size of theheating section 221 to make clearance fitting between theheating section 221 and the insertion opening 111 and facilitating the insertion and withdrawal of theheating section 221, and also to have residues, such as the aerosol forming base that sticks to theheating section 221 after heating, remaining on theheating section 221 to be scraped off by thebottom wall 112 through friction in separating theheating section 221 from theaerosol generation substrate 3, so as to carry out cleansing of theheating section 221. In the instant embodiment, theheater 22 is made in the form of a plate, and theinsertion opening 111 is a rectangle of which the cross-sectional size is slightly greater than the cross-sectional size of theheating section 221. It is appreciated that in other embodiments, theheater 22 can be mounted to the main body 2 in a removable and detachable manner. - The extractor 1 has a first position in which the extractor 1 is connected to the main body 2 and a second position in which the extractor 1 is separated from the main body 2. When the extractor 1 and the main body 2 are connected, the
first housing 11 and thesecond housing 21 are positioned each other and abut against each other, and the firstmagnetic body 13 in the bottom of thefirst housing 11 and the secondmagnetic body 23 in the top of thesecond housing 21 are placed close to each other and attract each other, so that by means of the attraction force between the firstmagnetic body 13 and the secondmagnetic body 23, the extractor 1 and the main body 2 are fixed to each other. Theheater 22 penetrates inward through theinsertion opening 111 in the bottom of the extractor 1, so as to have theheating section 221 completely inserted into the receivingspace 110. Theaerosol generation substrate 3 is disposed into the extractor 1 from the top thereof. The battery in the main body 2 supplies electricity to theheater 22, and theheater 22, after being supplied with electricity, heats up to subject theaerosol generation substrate 3 to heating and baking (at this moment, the extractor 1 and the main body 2 are located at the first position where they are connected). - When heating of the
aerosol generation substrate 3 is completed, pulling upward the extractor 1 makes the firstmagnetic body 13 and the secondmagnetic body 23 separating from each other and the extractor 1 and the main body 2 are then separated from each other (at this moment, the extractor 1 and the main body 2 are located at the second position where they are separated from each other), and at this moment, there is no connection between the extractor 1 and the main body 2, the extractor 1 drives, by means of thebottom wall 112 of the receivingspace 110, theaerosol generation substrate 3 to move upwards, causing theheating section 221 to withdraw from theaerosol generation substrate 3 and, at the same time, thebottom wall 112 scrapes off residue substances sticked to an outside of theheating section 221. -
FIGS. 3-4 show an aerosol generation device according to a second embodiment of the present invention, and the embodiment is primarily different from the first embodiment in that in the instant embodiment, anextraction tube 12 in the form of a circular tube extends downward from the top wall of thefirst housing 11. An inside wall of theextraction tube 12 defines and delimits the receivingspace 110 in which theaerosol generation substrate 3 is receivable. Further, in the instant embodiment, theseat 24 may comprise a base 241 that is fit inside thesecond housing 21 and acover 243 in the form of a cylinder extending from atop wall 2412 of thebase 241. Thecover 243 is sleeved around theheater 22 to prevent theheater 22 from being damaged due to impact by lateral shifting of thefirst housing 11 during connecting of the extractor 1 and the main body 2. Thecover 243 is arranged between thefirst housing 11 and theextraction tube 12 and forms spacing with respect to each of an inner wall surface of thefirst housing 11 and an outer wall surface of theextraction tube 12. In some embodiments, spacing distances of thecover 243 from the inner wall surface of thefirst housing 11 and the outer wall surface of theextraction tube 12 can be 0.5-5mm, preferably 3-5mm. -
FIGS. 5-7 show an aerosol generation device according to a third embodiment of the present invention, and the embodiment is primarily different from the second embodiment in that in the instant embodiment, theextraction tube 12 comprises astationary tube 121 and amovable tube 122 that are sleeved over each other and is slidable with respect to each other in an axial direction. Inner wall surfaces of thestationary tube 121 and themovable tube 122 jointly define and delimit the receivingspace 110 in which theaerosol generation substrate 3 is receivable. - Specifically, in the instant embodiment, the
stationary tube 121 is tightly fit, at an upper end thereof, into the top wall of thefirst housing 11, and is fixed to thefirst housing 11 by means of various ways, such as screw connection and snap connection. Themovable tube 122 is sleeved over a lower end of thestationary tube 121 in a manner of being axially slidable up and down. Themovable tube 122 has a bottom wall that forms thebottom wall 112 of the receivingspace 110. A top of themovable tube 122 is extended inwardly to form aflange 1221. An outer circumference of the lower end of thestationary tube 121 is raised outward to form a raised/convex platform 1211. Theflange 1221 and the raisedplatform 1211 cooperate with each other to prevent thestationary tube 121 and themovable tube 122 from detaching from each other during relative sliding therebetween. In some embodiments, a sliding stroke of themovable tube 122 relative to thestationary tube 121 is 2.5-5.5mm, such as around 4.5mm. - A first snap engagement section is formed on an outside of a top end of the main body 2, and a second snap engagement section is formed in an inside of a bottom end of the extractor 1 and is engageable with the first snap engagement section, wherein the first snap engagement section has an axial length that is smaller than or equal to the sliding stroke of the
movable tube 122 relative to thestationary tube 121. Specifically, in the instant embodiment, theseat 24 comprises a base 241 that is fit into thesecond housing 21, afitting section 242 extending upward from a top wall of thebase 241, and acover 243 extending from a top wall of thefitting section 242. Thebase 241, thefitting section 242, and thecover 243 having inside diameters and outside diameters that are sequentially reduced in a step-by-step manner. Thefitting section 242 has an outer wall surface that forms the first snap engagement section. The firstmagnetic body 13 forms the second snap engagement section. When the extractor 1 and the main body 2 are connected together, the firstmagnetic body 13 is tightly fit outside thefitting section 242 to thereby enhance stability of the connection between the extractor 1 and the main body 2. Thefitting section 242 has an axial length that is smaller than the sliding stroke of themovable tube 122 relative to thestationary tube 121. In some embodiments, the axial length of thefitting section 242 is 1-2.5mm, preferably around 2mm. In other embodiments, the firstmagnetic body 13 and the secondmagnetic body 23 can be omitted, and the connection between the extractor 1 and the main body 2 is achieved through the two fitting to each other, such as the bottom of thefirst housing 11 being directly fit over the outside of thefitting section 242, and under this condition, the second snap engagement section can be formed by inward extension from an inner wall surface of a bottom end of thefirst housing 11. - The
fitting section 242 is formed with a throughhole 2421 through which theheating section 221 is insertable. Theheating section 221 is capable of extending, in sequence, through the throughhole 2421 and theinsertion opening 111 to insert upward into theaerosol generation substrate 3. In the instant embodiment, a cross-sectional shape and size of the throughhole 2421 are consistent with a cross-sectional shape and size of theinsertion opening 111. When theheating section 221 is separated from theaerosol generation substrate 3, a hole wall of the throughhole 2421 applies an effect of friction to scrape off residual substances remaining on theheating section 221. In other embodiments, the cross-sectional size of the throughhole 2421 can be greater than the cross-sectional size of theinsertion opening 111. In some other embodiments, the cross-sectional shape of the throughhole 2421 can be different from the cross-sectional shape of theinsertion opening 111. - Considering an example, where the sliding stroke of the
movable tube 122 relative to thestationary tube 121 is 4.5mm, and the axial length of thefitting section 242 is 2mm, as shown inFIG. 5 , when the extractor 1 is at the first position, the extractor 1 and the main body 2 are positioned against each other, and at this moment, the firstmagnetic body 13 of the extractor 1 is fit over and around the outside of thefitting section 242 of the main body 2 and attracts the secondmagnetic body 23, the lower end face of themovable tube 122 abutting against the top wall of thefitting section 242, the lower end face of thestationary tube 121 abutting against thebottom wall 112 of themovable tube 122. Theaerosol generation substrate 3 is mounted into thestationary tube 121 from the top thereof to abut against thebottom wall 112 of themovable tube 122, and theheating section 221 of theheater 22 extends from theinsertion opening 111 on the bottom of themovable tube 122 to insert into theaerosol generation substrate 3, so that after electricity is supplied and heating is carried out, theaerosol generation substrate 3 is heated and baked. - After heating of the
aerosol generation substrate 3 is finished, thefirst housing 11 is pulled upward first, and thefirst housing 11 drives thestationary tube 121 and the firstmagnetic body 13 to move upwards. When the upward movement exceeds 2mm, the firstmagnetic body 13 and thefitting section 242 are separated from each other, so as to separate the extractor 1 and the main body 2 from each other. At this moment, since the raisedplatform 1211 of thestationary tube 121 has not yet being moved upward to contact with theflange 1221 of themovable tube 122, themovable tube 122, theaerosol generation substrate 3, and theheater 22 are kept relatively immobile. As shown inFIG. 6 , continuing pulling thefirst housing 11 upward to reach a displacement of 4.5mm makes the raisedplatform 1211 upward moving to get into contact with theflange 1221, and at this moment, further pulling thefirst housing 11 would cause thestationary tube 121 to drive themovable tube 122 to move upward together and themovable tube 122 in turn drives, through thebottom wall 112, theaerosol generation substrate 3 to move upward; and then, further pulling upward thefirst housing 11 would make theaerosol generation substrate 3 separating from theheating section 221, as shown inFIG. 7 , and at the same time, thebottom wall 112 may scrape off the residual substances sticking to the outside of theheating section 221. - As shown in
FIG. 8 , the aerosol generation device in the instant embodiment may further comprises aninternal seat 25 fit inside theseat 24. Theinternal seat 25 and theseat 24 jointly form a seat assembly for receiving theheater 22 to insert therein and for supporting the extractor 1. The secondmagnetic body 23 is tightly fit inside theinternal seat 25. The firstmagnetic body 13 is fit outside thefitting section 242 and forms anair passage gap 130 with respect to a top end surface of thebase 241. A top end face of theinternal seat 25 and a bottom end face of thefitting section 242 define therebetween anair flow channel 240 surrounding theheater 22. Two opposite sides of a sidewall on the bottom of thefitting section 242 are each formed with anair flow hole 2420 in communication with theair flow channel 240. Two opposite sides of a bottom part of the sidewall of thefirst housing 11 are each formed with anair inlet hole 120. External air moves, in sequence, through theair inlet hole 120, theair passage gap 130, and theair flow hole 2420 to get into theair flow channel 240 for cooling down the seat assembly, and then, the air carrying heat moves, in sequence, through the throughhole 2421 and theinsertion opening 111 to get into the interior of theaerosol generation substrate 3 in the receivingspace 110. The air so preheated helps enhance the atomization efficiency and makes a temperature distribution inside theaerosol generation substrate 3 more uniform. - It is appreciated that in other embodiments, the
air inlet hole 120 can be formed in the sidewall or the bottom wall of thesecond housing 21. Theair passage gap 130 between the bottom surface of the firstmagnetic body 13 and the top end surface of the base 241 can be omitted, provided a gas flow is conducted to flow over the surface of the seat assembly to cool down the seat assembly, such as theair inlet hole 120 can be formed in thesecond housing 21 and located between theseat 24 and theinternal seat 25, and then enters theair flow channel 240 through the gap between theseat 24 and theinternal seat 25. Theair flow channel 240 may not surround theheater 22, such as theair inlet hole 120 may be formed in a bottom of thesecond housing 21 and theair flow channel 240 extends in the longitudinal direction and parallel with the longitudinal direction of theheater 22. - It is appreciated that the technical features described above can be combined in an arbitrary way for use, without being limited.
- It is appreciated that the embodiments provided above illustrate only the preferred embodiments of the present invention and should not be construed as being limitative to limit the patent scope of the present invention. It is noted that for those having ordinary skill in the field, the technical features described above can be freely combined provided they do not depart from the inventive concept of the present invention, and various deformations and improvements can also be made, all these being considered belonging to the scope of protection that the present invention pursues. Thus, equivalent substitutions and modifications, which are made within the scope of the claims of the present invention should be construed falling within the scope of protection of the claims of the present invention.
