For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0047] The embodiments of the present invention are described in detail below, and examples of the embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals throughout represent the same or similar elements or elements having the same or similar functions. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain the present invention, and cannot be understood as limiting the present invention.

[0048] like Figures 1 to 7 As shown, this embodiment provides an aerosol generating device, which is a heat-not-burn device, which generates aerosol by heating an aerosol generating product 1000 for the user to inhale. The aerosol generating device can determine whether the aerosol generating product 1000 is basically inserted into place by the rotation of the trigger component 300, and does not require whether the aerosol generating product 1000 has a sensible mark, thereby improving the user's experience. The aerosol generating product 1000 is in the shape of a cigarette.

[0049] The aerosol generating device comprises a power source 500, a main body 100, a heating element 200, an induction switch 400 and a trigger assembly 300. The main body 100 is provided with a first cavity 111, which can removably accommodate at least a portion of an aerosol generating product 1000; the heating element 200 is used to heat the aerosol generating product 1000 to generate an aerosol; the induction switch 400 is provided in the main body 100 and is electrically connected to the power source 500, and the power source 500 is configured to electrically connect the heating element 200 or provide power for heating the heating element 200 when the induction switch 400 is triggered; the trigger assembly 300 is provided in the main body 100 and can rotate between a first position and a second position, and trigger the induction switch 400 when it is in the second position; wherein the trigger assembly 300 is configured to rotate from the first position to the second position when the aerosol generating product 1000 is loaded into the first cavity 111.

[0050] With the aid of the above arrangement, when the aerosol generating product 1000 is loaded into the first cavity 111, the trigger assembly 300 rotates from the first position to the second position. There is no requirement for whether the aerosol generating product 1000 has a sensible mark. The aerosol generating device can determine whether the aerosol generating product 1000 is basically inserted into place by rotating the trigger assembly 300, and can successfully trigger the sensing switch 400, thereby improving the user experience.

[0051] Combination Figures 2 to 4 As shown, regarding the structure of the trigger assembly 300, in some embodiments, the trigger assembly 300 includes a roller 310 rotatably connected to the main body 100, and at least a portion of the roller 310 is disposed in the first cavity 111. The arrangement of the roller 310 enables the roller 310 to be directly or indirectly driven by the aerosol generating article 1000 during the process of loading the aerosol generating article 1000 into the first cavity 111, so as to be able to rotate from the first position to the second position; at the same time, the roller 310 has a simple structure, is easy to produce, and has a low cost.

[0052] The roller 310 may include a rolling body 311 and two rotating shafts 312 respectively disposed at two ends of the rolling body 311 , and the two rotating shafts 312 are both rotatably matched with the rotating holes on the main body 100 .

[0053] In some embodiments, the trigger assembly 300 further includes a trigger portion 320, which is arranged in linkage with the roller 310, so that the position or shape of the trigger portion 320 can change with the rotation of the roller 310. Based on this, the induction switch 400 includes a proximity switch. When the trigger assembly 300 is located at the second position, the position or shape of the trigger portion 320 can trigger the proximity switch. This arrangement allows the trigger portion 320 to be hidden and isolated from the first cavity 111, thereby preventing aerosol from adhering to the trigger portion 320, protecting the trigger portion 320 and maintaining the performance of the trigger portion 320. During the rotation of the roller 310, the trigger portion 320 is linked thereto, thereby changing its position or shape to trigger the induction switch 400. During the process of the trigger portion 320 triggering the induction switch 400, it is possible not to have substantial contact with the induction switch 400, so as to avoid mechanical damage to the induction switch 400 caused by long-term use, thereby improving the service life and reliability of the induction switch 400.

[0054] In the first implementation of the present embodiment, the proximity switch includes a Hall switch, and the triggering part 320 includes a magnetic part. That is, when the triggering component 300 is located in the second position, the triggering part 320 can trigger the Hall switch by magnetic force. Specifically, the magnetic part can be a magnet or an electromagnet. When the triggering component 300 is located in the second position, the distance between the triggering part 320 and the Hall switch increases to the triggering distance, thereby triggering the Hall switch, and the induction switch 400 is therefore triggered; or the distance between the triggering part 320 and the Hall switch decreases to the triggering distance, thereby triggering the Hall switch, and the induction switch 400 is therefore triggered.

[0055] In a second implementation of this embodiment, the proximity switch includes a photoelectric switch, the trigger portion 320 includes a reflective surface, and when the trigger assembly 300 is located at the second position, light is reflected by the reflective surface to the photoelectric switch, thereby triggering the photoelectric switch, and the induction switch 400 is therefore triggered.

[0056] In a third implementation of this embodiment, the proximity switch includes a photoelectric switch, the trigger portion 320 includes a shielding piece, and when the trigger assembly 300 is located in the second position, the light emitted by the photoelectric switch is blocked by the shielding piece, thereby triggering the photoelectric switch, and the induction switch 400 is therefore triggered.

[0057] In some embodiments, the proximity switch may also be an inductive proximity switch, and the trigger portion 320 is made of metal. When the trigger assembly 300 is located at the second position, the trigger portion 320 of metal triggers the inductive proximity switch, and the inductive switch 400 is thus triggered. In some embodiments, the proximity switch may be a capacitive proximity switch, that is, two plates are provided on the main body 100. When the trigger assembly 300 is located at the second position, the trigger portion 320 is located between the two plates, thereby triggering the capacitive proximity switch, and the inductive switch 400 is thus triggered.

[0058] In some embodiments, the sensing switch 400 may include an angle sensor. The angle sensor is different from the proximity switch. The angle sensor can detect the rotation angle of the roller 310. When the trigger assembly 300 is in the second position, the angle sensor detects that the roller 310 rotates to the trigger angle, so that the power supply 500 is electrically connected to the heating element 200 or provides power for heating the heating element 200.

[0059] In some embodiments, the induction switch 400 may further include a gyroscope, which is disposed on the roller 310. When the trigger assembly 300 is located in the second position, the gyroscope detects that the roller 310 rotates to the trigger position, thereby enabling the power supply 500 to electrically connect to the heating element 200 or provide power for heating the heating element 200.

[0060] In some embodiments, the trigger part 320 is fixed on the roller 310 so that it can rotate relative to the main body 100 together with the roller 310 to realize linkage with the roller 310. Exemplarily, the rolling body 311 is provided with a first mounting groove 3111, and the trigger part 320 is installed in the first mounting groove 3111. This arrangement allows the trigger part 320 and the roller 310 to rotate synchronously, so that the range of motion of the trigger part 320 is easier to standardize, which is convenient for design and reduces costs. In some embodiments, the trigger part 320 can be connected to the roller 310 through a connecting rod or other transmission structure, so that the trigger part 320 is driven to move through the transmission mechanism during the rotation of the roller 310, so as to adapt to the complex structure of the main body 100 and avoid interference with other structures.

[0061] There are generally two ways for the heating element 200 to heat the aerosol generating product 1000, one of which is central heating and the other is circumferential heating. The central heating element 200 needs to be at least partially inserted into the aerosol generating product 1000 during heating, and when the heating element 200 generates heat, the heat is transferred from the inside to the outside. The circumferential heating element 200 needs to be arranged on the periphery of the aerosol generating product 1000 during heating, and when the heating element 200 generates heat, the heat is transferred from the outside to the inside.

[0062] The central heating type heating element 200 is used as an example for explanation. In order to avoid the adhesion between the heating element 200 and the aerosol generating article 1000 during heating, which makes it difficult to pull out the aerosol generating article 1000 or causes the aerosol generating article 1000 to break during the process of generating the aerosol generating article 1000, in some embodiments, the aerosol generating device includes an extractor 600 capable of accommodating at least a portion of the aerosol generating article 1000, and at least a portion of the extractor 600 is movably disposed in the first cavity 111; when the extractor 600 is located in the third position, at least a portion of the heating element 200 passes through the bottom of the extractor 600 and is disposed in the extractor 600 to be inserted into the interior of the aerosol generating article 1000. The extractor 600 has a second cavity 610 and a cavity opening 620 communicating with the second cavity 610, and at least a portion of the aerosol generating article 1000 can be loaded into the second cavity 610. The bottom of the extractor 600 has a supporting portion 640 , and the supporting portion 640 is provided with an avoidance hole 641 . When the extractor 600 is located at the third position, it is closer to the bottom of the first cavity 111 , and at least a portion of the heating element 200 passes through the avoidance hole 641 .

[0063] The above arrangement enables that when the extractor 600 moves upward in the third position, the supporting portion 640 moves upward while holding the lower end of the aerosol generating product 1000, thereby loosening the connection between the aerosol generating product 1000 and the heating element 200, making it easier to subsequently pull out the aerosol generating product 1000 and preventing the aerosol generating product 1000 from breaking.

[0064] In this embodiment, the extractor 600 is configured to move from the fourth position to the third position during the process of loading the aerosol generating product 1000 into the first cavity 111, and the extractor 600 is rollingly connected with the roller 310 during at least a portion of the movement between the third position and the fourth position. During the process of loading the aerosol generating product 1000 into the first cavity 111, the aerosol generating product 1000 pushes the extractor 600 to move to the third position, and during at least a portion of the movement of the extractor 600 from the fourth position to the third position, the extractor 600 causes the roller 310 to rotate by rolling contact with the roller 310, so that the aerosol generating product 1000 indirectly drives the roller 310 to rotate, and during the process of the extractor 600 moving to the third position, the roller 310 rotates from the first position to the second position, so that the induction switch 400 is triggered. The fourth position may be a certain position inside the first cavity 111. The extractor 600 can reciprocate between the third position and the fourth position in the first cavity 111. The extractor 600 can contact the roller 310 at the fourth position. The extractor 600 can be configured to be inseparable from the first cavity 111, and of course can also be configured to be able to be removed from the first cavity 111.

[0065] When the extractor 600 is located at the fourth position, the aerosol generating product 1000 can be loaded into the second cavity 610 and abut the supporting portion 640 of the second cavity 610, and then continue to press the aerosol generating product 1000 so that the extractor 600 and the aerosol generating product 1000 move together toward the bottom of the first cavity 111. In this state, the heating element 200 can be inserted into the aerosol generating product 1000 or the depth of insertion into the aerosol generating product 1000 gradually increases.

[0066] In other embodiments, the extractor 600 may be withdrawn and then the aerosol generating article 1000 may be loaded into the second cavity 610 , and then the extractor 600 together with the aerosol generating article 1000 may be loaded into the first cavity 111 .

[0067] The roller 310 is driven by the extractor 600, and the relative size and position relationship of the extractor 600 and the roller 310 are designed to effectively ensure the success rate of driving and improve the user experience.

[0068] During at least a portion of the travel of the extractor 600 moving from the third position to the fourth position, the extractor 600 is in rolling contact with the roller 310 and is able to drive the roller 310 to rotate in the opposite direction, thereby restoring the roller 310 from the second position to the first position, thereby releasing the trigger of the induction switch 400. In this state, the power supply 500 is no longer electrically connected to the heating element 200 or no longer provides power to the heating element 200.

[0069] Combination Figure 6 As shown, in some embodiments, during the process of loading the aerosol generating article 1000 into the first cavity 111, the aerosol generating article 1000 directly contacts the roller 310 to drive the roller 310 to rotate. Based on this, a window 630 is provided on the side wall of the extractor 600. During at least a part of the travel of the extractor 600 between the third position and the fourth position, a part of the roller 310 is located in the window 630 or passes through the window 630 and is located inside the extractor 600 to be rollingly connected with the aerosol generating article 1000. This arrangement allows the roller 310 to rub against the roller 310 during the loading process of the aerosol generating article 1000, thereby causing the roller 310 to rotate.

[0070] During at least part of the process of pulling the aerosol generating product 1000 out of the first cavity 111, the aerosol generating product 1000 is in rolling contact with the roller 310 and is able to drive the roller 310 to rotate in the opposite direction, thereby restoring the roller 310 from the second position to the first position, thereby releasing the trigger of the induction switch 400. In this state, the power supply 500 is no longer electrically connected to the heating element 200 or no longer provides power to the heating element 200.

[0071] When the aerosol generating product 1000 is not loaded into the first cavity 111, the trigger assembly 300 needs to be kept in the first position to avoid automatically moving to the second position and then erroneously triggering the sensing switch 400. In some embodiments, the main body 100 includes a first stopper 140. When the trigger assembly 300 rotates to the first position, the first stopper 140 interferes with the trigger assembly 300, so that the trigger assembly 300 remains in the first position. The above arrangement effectively prevents the trigger assembly 300 from rotating to the second position when the aerosol generating product 1000 is not loaded into the first cavity 111, thereby preventing the sensing switch 400 from being triggered, and preventing the heating element 200 from dry burning when it is not in contact with the aerosol generating product 1000, thereby improving the safety of the aerosol generating device.

[0072] Regarding the structure of the first stopper 140, in some embodiments, the first stopper 140 interferes with the trigger assembly 300 through magnetic attraction or magnetic repulsion. In one example of the present application, the induction switch 400 includes a Hall switch, the trigger part 320 includes a magnetic member fixed on the roller 310, and the first stopper 140 includes a magnet or an electromagnet, so when the trigger assembly 300 / roller 310 is in the first position, there is a magnetic repulsion or magnetic attraction between the trigger part 320 and the first stopper 140, so that the trigger assembly 300 can be maintained in the first position. In other embodiments, the trigger assembly 300 includes a magnetic member that can be adsorbed by the magnetic member and is independent of the trigger part 320. A magnetic attraction can be generated between the magnetic member and the first stopper 140, so that the trigger assembly 300 is maintained in the first position. The magnetic member can be a stainless steel block or an iron block.

[0073] Combination Figure 7 As shown, the main body 100 is provided with a second mounting groove 112, and the first stopper 140 is installed in the second mounting groove 112. In some embodiments, the first stopper 140 is interference fit or bonded to or snap-fitted to or integrally formed in the second mounting groove 112.

[0074] Since the roller 310 is rotatably disposed on the main body 100, in this embodiment, the main body 100 includes a second stopper. When the trigger assembly 300 rotates to the second position, the second stopper interferes with the trigger assembly 300 to prevent the trigger assembly 300 from continuing to rotate. With the above arrangement, when the trigger assembly 300 rotates to the second position, the trigger assembly 300 can be prevented from continuing to rotate along the original rotation direction, thereby preventing the trigger assembly 300 from being released due to the change in the positional relationship between the trigger assembly 300 and the sensor switch 400 during the continued rotation. In particular, when the trigger assembly 300 includes a proximity switch, if the sensor switch 400 needs to remain in the triggered state, the trigger assembly 300 needs to be maintained in the second position.

[0075] Exemplarily, a slide groove 3112 is provided on one of the trigger assembly 300 and the second stopper, and the other includes a slider 113. When the trigger assembly 300 rotates between the first position and the second position, the slider 113 slides along the slide groove 3112, and when the trigger assembly 300 rotates to the second position, the slider 113 is stopped by the end of the slide groove 3112. Further, when the trigger assembly 300 rotates to the first position, the slider 113 is stopped by the other end of the slide groove 3112. The above arrangement enables the trigger assembly 300 to rotate only within a certain angle range, ensuring that the trigger assembly 300 stops at the first position or the second position during the rotation process, and can prevent the trigger assembly 300 from rotating 360° or more than 360°.

[0076] Combination Figure 3 and Figure 7 As shown, in one implementation of this embodiment, the second stopper includes a slider 113 , the second stopper is disposed on the main body 100 , and a slide groove 3112 is disposed on the roller 310 of the trigger assembly 300 .

[0077] In another implementation of this embodiment, the second stopper is provided with a sliding groove 3112 , and a sliding block 113 is provided on the roller 310 of the trigger assembly 300 .

[0078] The main body 100 includes an insulation tube 110, a cover body 120 and a sealing member 130. The cover body 120 is covered at the opening of the insulation tube 110. The insulation tube 110 and the cover body 120 surround a first cavity 111. The sealing member 130 is sandwiched between the insulation tube 110 and the cover body 120 and is arranged around the outer periphery of the first cavity 111.

[0079] The bearing groove 114 is recessed at the upper edge of the heat preservation tube 110, and the cover 120 blocks the notch of the bearing groove 114 to form a rotation hole. The second mounting groove 112 is provided at the upper edge of the heat preservation tube 110, and the cover 120 blocks the notch of the second mounting groove 112 to fix the first stopper 140 in the second mounting groove 112. The above arrangement facilitates the installation of the trigger assembly 300 and the first stopper 140, and can prevent smoke from flowing out through the gap between the heat preservation tube 110 and the cover 120.
