Description

[Technical field]

[0001] The present invention relates to the field of atomization, and more specifically to aerosol generating devices. [Background technology]

[0002] A non-combustion / heating type atomizer is an aerosol generating device that forms an inhalable aerosol by heating the atomization material using a low-temperature non-combustion / heating method. Currently, non-combustion / heating type atomizers generally insert a heater such as a heating sheet into the aerosol-forming substrate to heat it. Then, by controlling the heating temperature, the components in the aerosol-forming substrate are volatilized to generate an aerosol for inhalation.

[0003] After one aerosol-forming substrate is heated for a certain period of time and the amount of aerosol generated reaches an upper limit, it is necessary to either remove the aerosol-forming substrate from the atomizer and stop inhalation, or replace it with a new aerosol-forming substrate and continue inhalation. At this time, it is extremely important how to easily and quickly remove the aerosol-forming substrate from the atomizer without damaging the aerosol-forming substrate or leaving any residue on the heater. In conventional non-combustion / heating type atomizers, the aerosol-forming substrate is generally removed from the atomizer by manually pulling it out. However, since the pulling force varies greatly depending on the strength applied by the user, many users often tear the aerosol-forming substrate when pulling it out, or the contact part between the aerosol-forming substrate and the heater becomes sticky, forming a residue on the heater. This affects the heating effect the next time it is used, for example by generating a burnt odor. Summary of the Invention [Problem to be solved by the invention]

[0004] The technical problem that the present invention aims to solve is to provide an improved aerosol generating device that overcomes the above-mentioned shortcomings in the prior art. [Means for solving the problem]

[0007] The ejection device includes an elastic component. When the ejection device is connected to the body, the aerosol-forming substrate is located at a first position where it can be heated by the heating element. When the ejection device is separated from the body, at least a portion of the heating element is removed from the accommodation space, so that the aerosol-forming substrate is located at a second position where at least a portion of the heating element is separated from the accommodation space. The elastic component is used to change the length of the accommodation space during the process of the ejection device and the body being separated from each other.

[0008] In some embodiments, the removal device includes an upper cover, a fixed tube fixedly connected to the upper cover, and a movable tube slidably fitted into the fixed tube, and the inner wall surfaces of the fixed tube and the movable tube collectively define the storage space.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS

[0030] In order to make the technical features, objects and effects of the present invention more clearly understandable, specific embodiments of the present invention will be described in detail with reference to the drawings.

[0031] 1 to 6 show an aerosol-generating device 100 according to a first embodiment of the present invention. The aerosol-generating device 100 can be used to release an aerosol extract in the aerosol-forming substrate in a non-combustion state by baking the aerosol-forming substrate 200 inserted therein at a low temperature. The aerosol-forming substrate 200 may be cylindrical and includes an atomization section 201. The atomization section 201 may include a solid substrate such as a plant leaf. Furthermore, the aerosol-forming substrate 200 may include a hollow support section 202, a temperature-reducing section 203, and a filtration section 204, which are provided above the atomization section 201 in the vertical direction. The aerosol-generating device 100 may be substantially rectangular prism-shaped. In addition, an insertion port 210 whose shape and size are adapted to the aerosol-forming substrate 200 is provided in the ceiling of the aerosol-generating device 100. As can be understood, the aerosol generating device 100 is not limited to a rectangular prism shape, but may have other shapes such as a circular cylinder, an elliptical cylinder, and the like.

[0032] The aerosol generating device 100 may include a main body 1 and an ejection device 2 disposed above the main body 1 so as to be vertically separable. A storage space 220 for accommodating the aerosol-forming substrate 200 is formed inside the ejection device 2. The aerosol-forming substrate 200 can be inserted into the storage space 220 via an insertion port 210. The main body 1 may include a body 11, a heating element 14 disposed in the body 11, a motherboard 16 disposed in the body 11, and a battery 17 disposed in the body 11. The motherboard 16 is electrically connected to the battery 17 and the heating element 14, respectively. A related control circuit is disposed in the motherboard 16, and the battery 17 can be controlled to supply electricity to the heating element 14 by activating the motherboard 16 using a switch 19 disposed in the body 11. The upper end of the heating element 14 can extend into the storage space 220 and be inserted into the aerosol-forming substrate 200, and can be in firm contact with the aerosol-forming substrate 200. The heating element 14 generates heat by energization, and then transmits the heat to the aerosol-forming substrate 200, thereby realizing baking heating of the aerosol-forming substrate 200. The heating element 14 may be a resistance heating element, or may be a metallic induction heating element capable of generating heat in a changing magnetic field. The heating element 14 may be in the form of a sheet or a rod. In addition, a pointed end guide structure may be provided at the upper end of the heating element 14 to facilitate insertion into the aerosol-forming substrate 200.

[0033] The ejection device 2 may include an upper cover 21 detachably disposed on the body 11, a storage module 22 provided in the upper cover 21, and an elastic component 23 provided in the upper cover 21. When the ejection device 2 is connected to the body 11, the aerosol-forming substrate 200 is located at a first position where it can be heated by the heating element 14. When the ejection device 2 is separated from the body 11, at least a part of the heating element 14 is removed from the storage space 220, and the aerosol-forming substrate 200 is located at a second position where at least a part of the heating element 14 is separated from the heating element 14. The elastic component 23 is used to change the length of the storage space 220 during the process in which the ejection device 2 and the body 11 are connected to each other and separated from each other.

[0034] Specifically, the accommodating module 22 may include a fixed tube 221 located at an upper portion and fixedly connected to the upper cover 21, and a movable tube 222 located at a lower portion and slidably fitted into the fixed tube 221. The inner wall surfaces of the fixed tube 221 and the movable tube 222 jointly define the accommodating space 220. The movable tube 222 can be disposed at the lower portion of the fixed tube 221 so as to be slidable in the vertical direction, and can be installed coaxially with the fixed tube 221. The movable tube 222 includes a bottom wall 2221. The bottom wall 2221 can be used to support the aerosol-forming substrate 200. The aerosol-forming substrate 200 can be inserted into the accommodating space 220 through the insertion opening 210 and abuts against the bottom wall 2221. The bottom wall 2221 has an insertion opening 2220 for inserting the heating body 14. The shape of the insertion opening 2220 may correspond to the cross-sectional shape of the heating body 14. The size of the cross section of the insertion opening 2220 may be slightly larger than that of the heating element 14. As a result, the heating element 14 is fitted into the insertion opening 2220 with a gap, which makes it easy to insert and remove the heating element 14. When the heating element 14 is separated from the aerosol-forming substrate 200, the bottom wall 2221 can scrape off the residual material adhering to the heating element 14 by friction, so that the heating element 14 can be cleaned. In this embodiment, the heating element 14 is sheet-shaped, and the insertion opening 2220 is rectangular in shape with a cross section slightly larger than that of the heating element 14. The lower end of the heating element 14 can be fitted into the heating base 15, and the heating element 14 is inserted into the upper part of the body 11 through the heating base 15.

[0035] The fixed tube 221 can be fixedly connected to the inside of the ceiling wall of the upper cover 21 by a screw connection, a hook connection, a magnetic attraction connection, or the like. The movable tube 222 is slidably fitted into the fixed tube 221. In other embodiments, the fixed tube 221 may be integrally formed with the upper cover 21. For example, the fixed tube 221 may be formed to extend integrally from the inside of the ceiling wall of the upper cover 21 downward in the vertical direction. The fixed tube 221 and the movable tube 222 may further be provided with position restriction structures that fit together to prevent them from falling off during sliding. In some embodiments, the position restriction structure may include a first position restriction protrusion 2213 located at the lower part and formed to extend radially inward from the inner wall surface of the fixed tube 221, and a second position restriction protrusion 2223 located at the upper part and formed to extend radially outward from the outer wall surface of the movable tube 222. Both ends of the elastic component 23 are connected to the fixed tube 221 and the movable tube 222, respectively. The upper end of the elastic component 23 can abut against the second position restricting protrusion 2223, and the lower end of the elastic component 23 can abut against the first position restricting protrusion 2213. The elastic component 23 enables the storage module 22 to be held so that the movable tube 222 does not move when the aerosol-forming substrate 200 is not inserted.

[0036] In some embodiments, the fixed tube 221 may include an outer tube 2211 and an inner tube 2212 disposed in the outer tube 2211. The movable tube 222 is slidably fitted into the outer tube 2211. In addition, the lower end of the outer tube 2211 extends radially inward to form a first position restricting protrusion 2213. The inner diameter of the outer tube 2211 may be larger than the outer diameter of the inner tube 2212.

[0037] In some embodiments, the movable tube 222 may include a first tube section 2222 located at the lower part and a second tube section 2224 located at the upper part and connected to the first tube section 2222. The second tube section 2224 is slidably disposed between the outer tube 2211 and the inner tube 2212. The outer diameter of the second tube section 2224 is larger than the outer diameter of the first tube section 2222 and is adapted to the inner diameter of the outer tube 2211. That is, the outer wall surface of the second tube section 2224 and the inner wall surface of the outer tube 2211 are fitted together so as to be in sliding contact with each other. In addition, a step surface formed between the second tube section 2224 and the first tube section 2222 forms a second position restricting protrusion 2223. A mounting space for mounting the elastic component 23 is formed between the inner wall surface of the outer tube 2211 and the outer wall surface of the first tube section 2222. The elastic component 23 may be a spring, and is disposed between an inner wall surface of the outer tube 2211 and an outer wall surface of the first tube section 2222 .

[0038] The inner diameter of the first pipe section 2222 may be equal or approximately equal to the inner diameter of the inner pipe 2212. The first pipe section 2222 is provided below the inner pipe 2212 in the axial direction. The inner diameter of the second pipe section 2224 is adapted to the outer diameter of the inner pipe 2212. That is, the outer wall surface of the inner pipe 2212 can be fitted so as to be in sliding contact with the inner wall surface of the second pipe section 2224. The second pipe section 2224 and the inner pipe 2212 may further be provided with at least one position restriction guide structure that is fitted with each other to guide the movable pipe 222 when it slides and to restrict the relative circumferential position of the movable pipe 222 and the inner pipe 2212. In this embodiment, there are two position restriction guide structures. The two position restriction guide structures are located on two opposing sides of the accommodation space 220, respectively. The position restriction guide structure may include a guide groove 2225 extending in the vertical direction and a guide protrusion 2214 slidably fitted in the guide groove 2225. Specifically, in this embodiment, the guide groove 2225 may be opened to penetrate the second pipe section 2224 and extend downward from the ceiling wall of the second pipe section 2224 to near the bottom. The guide protrusion 2214 is formed to extend outward from the outer wall surface of the inner pipe 2212. In addition, there may be two guide protrusions 2214. The two guide protrusions 2214 are fitted to both sides of the guide groove 2225 in the circumferential direction so as to slide thereon. The axial length of the guide groove 2225 is greater than the maximum sliding stroke of the movable pipe 222 relative to the fixed pipe 221. This prevents the guide protrusion 2214 from coming out of the guide groove 2225 when the upper cover 21 and the body 11 are separated. In addition, in other embodiments, there may be only one guide protrusion 2214. Both circumferential sides of the one guide protrusion 2214 are fitted into both circumferential sides of the guide groove 2225 so as to be in sliding contact with each other.

[0039] A guide portion 181 is formed at the upper end of the body 11, and the lower end of the upper cover 21 is slidably disposed in the guide portion 181. outer wallThe guide portion 181 is fitted to the upper cover 21 so as to slide against the surface. The guide portion 181 can exert a guiding effect in the process in which the upper cover 21 and the body 11 move from a connected state to a separated state. When the upper cover 21 and the guide portion 181 are in an arbitrary position when they are fitted to slide against each other, the aerosol-forming substrate 200 is located at a first position where it can be heated by the heating body 14. When the upper cover 21 and the guide portion 181 are in an arbitrary position when they are in sliding contact and separated, the aerosol-forming substrate 200 is located at a second position where at least a part of the substrate 200 is separated from the heating body 14. The axial height H0 of the guide portion 181 is equal to or less than the maximum sliding stroke of the movable tube 222 relative to the fixed tube 221. In this embodiment, the axial height H0 of the guide portion 181 is equal to the maximum sliding stroke of the movable tube 222 relative to the fixed tube 221. The ceiling portion of the guide portion 181 may further be formed with a tube cover 182 extending upward. The tube cover 182 is provided to cover the outside of the heating body 14. The tube cover 182 can prevent the upper cover 21 from moving laterally and crushing the heater 14 when the upper cover 21 and the body 11 are butted against each other. The tube cover 182 is provided between the upper cover 21 and the outer tube 2211, and has a gap between the inner wall surface of the upper cover 21 and the outer wall surface of the outer tube 2211. Specifically, the guide portion 181 and the tube cover 182 are both hollow and tubular, and are connected to each other. The size of the outer cross section of the guide portion 181 is larger than the size of the outer cross section of the tube cover 182, and corresponds to the size of the inner cross section of the upper cover 21. That is, the size of the outer cross section of the tube cover 182 is smaller than the size of the inner cross section of the upper cover 21. A support arm 183 may be further formed in the guide portion 181. The upper end surface of the support arm 183 may be capable of supporting the storage module 22, and a gap may be formed between the upper end surface of the storage module 22 and the lower end surface of the storage module 22. The lower end surface of the support arm 183 can press the heat generating base 15 to fix the heat generating base 15 in place.

[0040] As shown in FIG. 4, the upper cover 21 and the body 11 are butted against each other. At this time, the upper cover 21 is fitted to the outside of the guide portion 181 and contacts the guide portion 181. The fitting height between the lower end of the upper cover 21 and the guide portion 181 is the axial height H0 of the guide portion 181. The lower end surface of the upper cover 21 abuts against the upper end surface of the body 11. The upper end of the heating element 14 penetrates the bottom wall 2221 of the movable tube 222 and extends into the storage module 22. The elastic component 23 is in a semi-compressed state so that the upper end surface of the movable tube 222 elastically abuts against the lower end surface of the inner tube 2212 to prevent the movable tube 222 from wobbling. When not in use, i.e., when the aerosol-forming substrate 200 is not inserted into the storage module 22, the total length of the storage module 22 is the initial length L0, i.e., the sum of the lengths of the inner tube 2212 and the movable tube 222.

[0041] When inhalation is required, the aerosol-forming substrate 200 is inserted into the storage module 22, and the heater 14 is inserted into the bottom of the aerosol-forming substrate 200. The bottom of the aerosol-forming substrate 200 comes into contact with the bottom wall 2221 of the movable tube 222. The heater 14 generates heat by energization, and then bakes and heats the aerosol-forming substrate 200. During the process of inserting the aerosol-forming substrate 200, the force for inserting the aerosol-forming substrate 200 is usually small, so that the movable tube 222 is not moved downward, and the overall length of the storage module 22 is maintained at the initial length L0. On the other hand, when the force for inserting the aerosol-forming substrate 200 is large, the aerosol-forming substrate 200 may push the bottom wall 2221 of the movable tube 222, causing the movable tube 222 to move downward by a small distance. In this case, the overall length of the storage module 22 increases slightly and then returns to the initial length L0.

[0042] After the heating of the aerosol-forming substrate 200 is completed, the upper cover 21 is pulled to move upward in a direction away from the body 11. In the process of the upper cover 21 moving upward, the engagement height between the lower end of the upper cover 21 and the guide portion 181 gradually decreases. Meanwhile, the fixed tube 221 moves upward accompanying the upper cover 21, but the movable tube 222 and the aerosol-forming substrate 200 do not move. The first position restricting protrusion 2213 of the fixed tube 221 further compresses the elastic component 23 by moving upward. As a result, the overall length of the containing module 22 gradually increases, but the aerosol-forming substrate 200 and the heating body 14 do not move relative to each other. As shown in FIG. 5, when the upper cover 21 and the body 11 are just separated, the lower end of the upper cover 21 and the guide portion 181 are also just separated. That is, while the upper cover 21 and the guide part 181 slide relatively by H0, the fixed tube 221 also slides by the height H0 relative to the movable tube 222, so that the total length of the storage module 22 changes from L0 to L0+H0. Then, as shown in FIG. 6 , when the upper cover 21 continues to move upward, the movable tube 222 also moves upward together with the upper cover 21, and the bottom wall 2221 of the movable tube 222 moves the aerosol-forming substrate 200 upward to separate it from the heating body 14.

[0043] A dust cover 25 for covering or exposing the insertion opening 210 may be further provided on the ceiling of the upper cover 21. When the aerosol generating device 100 does not need to be used, the dust cover 25 can be pushed and moved to cover the insertion opening 210, thereby preventing dust from entering the insertion opening 210. When the aerosol generating device 100 needs to be used, the dust cover 25 is pushed and moved to expose the insertion opening 210 so that the aerosol-forming substrate 200 can be inserted through the insertion opening 210.

[0044] 7 shows an aerosol generating device 100 according to a second embodiment of the present invention. The main differences between the second embodiment and the first embodiment are as follows. That is, in this embodiment, the movable tube 224 is slidably disposed outside the fixed tube 223. In addition, in this embodiment, the elastic component 23 is fitted between the inner wall surface of the movable tube 224 and the outer wall surface of the fixed tube 223 accordingly. In addition, the first position restricting protrusion 2231 that abuts against the lower end of the elastic component 23 can be formed so as to extend radially outward from the outer wall surface of the fixed tube 223, and the second position restricting protrusion 2243 that abuts against the upper end of the elastic component 23 can be formed so as to extend radially inward from the inner wall surface of the movable tube 224.

[0045] Specifically, in this embodiment, the movable tube 224 may include a first tube section 2241 located at the bottom and a second tube section 2242 located at the top. The outer diameter and inner diameter of the second tube section 2242 may be larger than the outer diameter and inner diameter of the first tube section 2241, respectively. The fixed tube 223 is slidably installed in the second tube section 2242. In addition, the lower end of the fixed tube 223 is separably abutted against a step surface formed between the second tube section 2242 and the first tube section 2241. The inner diameter of the fixed tube 223 may be the same as the inner diameter of the first tube section 2241. Thus, when the upper cover 21 and the body 11 are butted against each other, the inner wall surface of the accommodation space 220 is smoothly connected. The inner diameter of the second tube section 2242 is larger than the inner diameter of the fixed tube 223. In addition, the elastic component 23 is fitted between the inner wall surface of the second pipe section 2242 and the outer wall surface of the fixed pipe 223. The first position restricting protrusion 2231 can be formed to extend radially outward from the outer wall surface of the lower end of the fixed pipe 223, and the second position restricting protrusion 2243 can be formed to extend radially inward from the inner wall surface of the upper end of the second pipe section 2242.

[0046] As can be understood, the above technical features can be used in any combination without limitation.

[0047] The above examples merely show specific embodiments of the present invention, and are described in a relatively specific and detailed manner, but should not be interpreted as limiting the scope of the present invention. It should be noted that those skilled in the art can freely combine the above technical features and make some modifications and improvements without departing from the concept of the present invention, all of which are within the scope of protection of the present invention.
