[0031] With reference to Fig. 1, Fig. 2 and Fig. 3, an aerosol generating device provided in an embodiment of the present application includes a body 100, a receiving portion 200, a driving mechanism 300 and a heating element 400. The receiving portion 200 is disposed in the body 100 and is formed with a chamber 200a for receiving a cigarette 500; the driving mechanism 300 is connected to the receiving portion 200 and is used to drive the receiving portion 200 to rotate; the heating element 400 is disposed in the body 100.

[0032] The aerosol generating device of the present application is provided with a rotatable containing part 200, so that the aerosol generating matrix can fully separate the residue and the heating element 400 during the rotation of the containing part 200, and the amount of residue adhering to the heating element 400 is reduced. Therefore, when the aerosol generating matrix is ​​taken out, the amount of residue falling into the containing part 200 is also reduced, and there is no need to frequently clean the containing part 200, thereby improving the user experience of the aerosol generating device.

[0033] In this embodiment, the cigarette 500 is used as an aerosol-generating substrate. The cigarette 500 is inserted into the receiving portion 200, and the cigarette 500 is heated by the heating element 400 to generate smoke in the form of aerosol for the user to inhale. As the receiving portion 200 rotates, the cigarette residue generated by the cigarette 500 separates from the heating element 400 and adheres to the cigarette 500, thereby reducing the amount of cigarette residue falling into the receiving portion 200.

[0034] Specifically, the heating element 400 is cylindrical, and in this embodiment, the heating element 400 is a heating tube or a heating rod connected to a power source (not shown). The chamber 200a is a cylindrical cavity formed by the accommodating portion 200, and is used to accommodate the cigarette 500 which is also cylindrical. The heating element 400 is arranged in the chamber 200a along the extension direction of the chamber 200a. When the cigarette 500 is placed in the chamber 200a, the heating element 400 is inserted into the cigarette 500 to heat the cigarette 500. When the cigarette 500 needs to be taken out of the chamber 200a, the driving mechanism 300 is started, and the driving mechanism 300 drives the accommodating portion 200 to drive the cigarette 500 to rotate. At this time, the cigarette residue adhered to the peripheral side of the heating element 400 is separated from the heating element 400 and adhered to the cigarette 500, and can be taken out together with the cigarette 500, thereby reducing the amount of cigarette residue dropped into the accommodating portion 200.

[0035] In some embodiments, the accommodating portion 200 is provided with an inner wall 210 corresponding to the chamber 200a, and an opening is formed at one end of the accommodating portion 200, the opening is used to guide the cigarette 500 to be inserted into the chamber 200a, and the inner wall 210 gradually converges in the direction away from the opening so that the diameter of the chamber 200a gradually decreases.

[0036] For example, taking the accommodating portion in FIG. 2 and FIG. 3 as an example, an opening is formed at the upper end of the accommodating portion 200, and the cigarette 500 is inserted into the chamber 200a through the opening. An annular inner wall 210 is provided inside the accommodating portion 200, and the inner wall 210 constitutes the edge of the chamber 200a. When the cigarette 500 is inserted into the chamber 200a, the outer surface of the cigarette 500 contacts the inner wall 210 and is limited by the inner wall 210. In the direction away from the opening, that is, from top to bottom in the figure, the inner wall 210 is in a state of gradually converging, that is, the diameter of the chamber 200a is gradually reduced, so that the part of the cigarette 500 close to the opening is in clearance fit with the inner wall 210, and the part of the cigarette 500 away from the opening is in interference fit with the inner wall 210. Therefore, when inserting the cigarette 500 into the chamber 200a, the bottom of the cigarette 500 and the inner wall 210 gradually change from a clearance fit to an interference fit, so that the user can feel the cigarette 500 go from loose to tight until it is fixed in the chamber 200a. In this way, this structural setting not only facilitates the insertion of the cigarette 500, but also improves the installation experience of the user when installing the cigarette 500.

[0037] In this embodiment, in the direction from top to bottom, that is, the direction of inserting the cigarette 500, the outer wall 220 of the accommodating portion 200 also presents a gradually converging shape, and when viewed from the angle shown in Fig. 3, the accommodating portion 200 is approximately an inverted trapezoid. In other embodiments, the outer wall 220 of the accommodating portion 200 may also be cylindrical or in other shapes.

[0038] In some embodiments, a rounded chamfered surface is provided along the circumferential direction at one end of the inner wall 210 away from the opening.

[0039] For example, referring to FIG3 , a rounded chamfered surface is provided along the circumferential direction at the end of the inner wall 210 away from the opening, that is, the bottom end of the inner wall 210. It can be understood that when the user gradually inserts the cigarette 500 downward to the bottom of the chamber 200a, the lower end of the cigarette 500 is squeezed by the rounded chamfered surface, so that the cigarette paper on the outer peripheral side of the lower end of the cigarette 500 shrinks inward along the radial direction of the cigarette 500 to form a closed end, thereby improving the wrapping effect of the cigarette paper on the tobacco, thereby reducing the amount of tobacco residue generated.

[0040] In some embodiments, the body 100 includes a box body 110 and a cover body 120, a first accommodating space 100a is formed in the box body 110, the cover body 120 is covered on one end surface of the box body 110 to form a second accommodating space 100b, the accommodating portion 200 is at least partially located in the second accommodating space 100b, the accommodating portion 200 is relatively provided with a first through hole 200b and a second through hole 200c, the first through hole 200b is used to guide the aerosol generating matrix into the chamber 200a, the diameter of the first through hole 200b is larger than the second through hole 200c, the heating element 400 passes through the second through hole, and at least part of the heating element 400 is located in the chamber 200a.

[0041] Exemplarily, referring to Fig. 1, Fig. 2 and Fig. 3, the box body 110 is approximately a rectangular parallelepiped, and the four right-angled edges along the periphery of the box body 110 are chamfered to make the four right-angled edges transition smoothly, and the box body 110 is more rounded and easy to hold. A first accommodating space 100a is formed in the box body 110. The cover body 120 is covered on one end face of the box body 110, and the cover body 120 is provided with a through hole, through which the user can insert the cigarette 500. The inner surface of the cover body 120 and the end face of the box body 110 are enclosed to form a second accommodating space 100b, most of the volume of the accommodating portion 200 is located in the first accommodating space 100a, and the top of the accommodating portion 200 is located in the second accommodating space 100b and is located directly below the through hole, so that the user can insert the cigarette 500 into the chamber 200a after aligning the accommodating portion 200 through the through hole.

[0042] The accommodating portion 200 is provided with a first through hole 200b and a second through hole 200c, and the first through hole 200b and the second through hole 200c are arranged opposite to each other. In this embodiment, the first through hole 200b is located at the top side of the accommodating portion 200, and is used to guide the cigarette 500 into the chamber 200a. The second through hole 200c is located at the bottom side of the accommodating portion 200. When the heating element 400 is installed, the heating element 400 passes through the second through hole 200c from bottom to top, and at least part of the heating element 400 is located in the chamber 200a.

[0043] In some embodiments, the driving mechanism 300 includes a driving member 310, a first gear 320 and a second gear 330. The driving member 310 has a rotating end, which is connected to the first gear 320 to drive the first gear 320 to rotate. The first gear 320 is meshed with the second gear 330, and the second gear 330 is connected to the accommodating portion 200.

[0044] Exemplarily, with reference to Fig. 1, Fig. 2 and Fig. 4, the driving member 310 is arranged in the first accommodating space 100a and is located on the right side of the first accommodating space 100a. The driving member 310 includes a motor 311, and the output end of the motor 311 is connected to a rotating shaft 312. The first gear 320 and the second gear 330 are arranged in the second accommodating space 100b and mesh with each other. The end of the rotating shaft 312 away from the motor 311 passes through the box body 110 and is fixedly connected to the first gear 320. When in use, the user starts the motor 311, the rotating shaft 312 drives the first gear 320 to rotate, and the second gear 330 rotates in the opposite direction relative to the first gear 320. The second gear 330 is provided with an inner hole 330a, the accommodating portion 200 passes through the inner hole 330a, and the outer peripheral surface of the accommodating portion 200 is fixedly connected to the annular wall of the second gear 330 corresponding to the inner hole 330a. Therefore, the second gear 330 can drive the accommodating portion 200 to rotate together. In other embodiments, the second gear 330 may be integrally formed with the accommodating portion 200, or the outer peripheral side of the accommodating portion 200 may be provided with a tooth portion that cooperates with the first gear 320. The driving member 310 is arranged in the first accommodating space 100a, and even if the cover 120 is opened and closed, it will not affect the driving member 310, which effectively protects the driving member 310 from being polluted by dust and smoke residue, so that the driving member 310 can work stably. The first gear 320 and the second gear 330 are arranged in the second accommodating space 100b, so that the heating member 400 is relatively far away from the first gear 320 and the second gear 330, so as to reduce the occupation of the first accommodating space 100a inside the box body 110, and the layout is more reasonable.

[0045] In some embodiments, the first gear 320 is provided with a fixing portion 331 , the rotating end includes a rotating shaft 312 , and the fixing portion 331 is used to abut against the circumferential side of the rotating shaft 312 .

[0046] Exemplarily, taking FIG. 2, FIG. 4 and FIG. 5 as examples, the rotating shaft 312 is arranged in the vertical direction, one end of the rotating shaft 312 is connected to the motor 311, and the other end is located in the second accommodating space 100b. The center of the first gear 320 is provided with an axial hole 320a, and the part of the rotating shaft 312 located in the second accommodating space 100b is penetrated in the axial hole 320a. The first gear 320 is provided with a fixing portion 331, which is arranged on the annular wall of the axial hole 320a. The fixing portion 331 abuts against the rotating shaft 312, so that the rotating shaft 312 and the first gear 320 generate a sufficiently large friction force and cannot rotate relative to each other, and then when the motor 311 is working, the rotating shaft 312 can drive the first gear 320 to rotate synchronously. In other embodiments, the fixing portion 331 can also fix the rotating shaft 312 by clamping or the like, and the fixing portion 331 can also be arranged on the two end faces of the first gear 320.

[0047] In some embodiments, the cross section of the rotating shaft 312 is square, and the fixing portion 331 includes a first clamping block 3311 and a second clamping block 3312 . The first clamping block 3311 and the second clamping block 3312 are respectively abutted against two opposite outer side surfaces of the rotating shaft 312 .

[0048] Exemplarily, referring to FIG5 , the cross section (not shown) of the rotating shaft 312 is square, and the fixing portion 331 includes a first clamping block 3311 and a second clamping block 3312, and the first clamping block 3311 and the second clamping block 3312 are both fixedly arranged on the annular wall corresponding to the first gear 320 and the shaft hole 320a, and the first clamping block 3311 and the second clamping block 3312 are symmetrically arranged on both sides of the center of the shaft hole 320a. The first clamping block 3311 and the second clamping block 3312 are respectively abutted against the opposite side surfaces of the rotating shaft 312. It can be understood that since the distance between the first clamping block 3311 and the second clamping block 3312 is equal to the distance between the opposite sides of the rotating shaft 312, the rotating shaft 312 cannot rotate between the first clamping block 3311 and the second clamping block 3312, that is, the rotating shaft 312 and the first gear 320 cannot rotate relative to each other. By setting a rotating shaft 312 with a square cross-section, and setting a first clamping block 3311 and a second clamping block 3312, the rotating shaft 312 can drive the first gear 320 to rotate by simply inserting the rotating shaft 312 between the first clamping block 3311 and the second clamping block 3312. This connection method does not require the use of screws and other parts for fixing, is convenient and fast, and is easy to install and disassemble.

[0049] In some embodiments, the cover 120 includes a transparent member to facilitate observation of the first gear 320 and the second gear 330 .

[0050] Exemplarily, referring to FIG1 , the material of the cover 120 is transparent plastic, and the specific type may be PC, ABS, acrylic, etc., and the material of the cover 120 may also be glass, etc. After the user starts the driving member 310 through the switch, the user can observe the rotation of the first gear 320 and the second gear 330 through the cover 120 to ensure that the first gear 320 and the second gear 330 are in a fully meshed state to rotate the accommodating portion 200. On the other hand, the user can observe the situation in the second accommodating space 100b through the cover 120, and the overall structure is more beautiful, which improves the user experience and fun.

[0051] In some embodiments, the aerosol generating device further comprises a mounting frame 130 , which is connected to the box body 110 , and a third accommodating space 100 c is formed inside the mounting frame 130 , and the heating element 400 is at least partially located in the third accommodating space 100 c .

[0052] Taking the mounting frame 130 shown in FIG. 2 as an example, the mounting frame 130 is shaped like a pocket, the top of the mounting frame 130 is connected to the box body, and most of the volume of the mounting frame 130 is located in the first accommodating space 100a. A third accommodating space 100c is formed in the mounting frame 130, and the heating element 400 is connected to the bottom side of the mounting frame 130. It can be understood that part of the heating element 400 and part of the accommodating portion 200 are both located in the mounting frame 130, and part of the heating element 400 is located in the accommodating portion 200. The mounting frame 130 can be made of heat-insulating material, and the heat preservation effect is better. By providing the mounting frame 130, it is easy to install the heating element 400 and prevent the heating element 400 from falling; by at least partially accommodating the heating element 400 in the third accommodating space 100c, heat loss can be reduced and the heating effect is better.

[0053] In some embodiments, the aerosol generating device further includes a controller and a battery. The controller is electrically connected to the driver 310 to control the start and stop of the driver 310 , and the battery is used to power the controller and the driver 310 .

[0054] Exemplarily, the aerosol generating device further includes a controller (not shown) and a battery (not shown). The controller includes an operation panel and a chip, and the operation panel is arranged on the outer surface of the combination, so that the user can touch and operate it conveniently. The chip is electrically connected to the operation panel and arranged in the box body 110. At the same time, the chip is also connected to the motor 311 to control the start and stop and the speed of the motor 311. The battery is also arranged in the box body 110, and the battery is used to power the controller and the driving member 310. By setting the controller, when the user smokes different types of cigarettes 500, the speed of the motor 311 can be adjusted to a suitable speed according to the adhesion of the cigarette residue in the cigarette 500, so as to obtain the ideal effect of separating the cigarette residue. The battery is built into the box body 110, which improves the portability and battery life of the aerosol generating device, and provides a better user experience.

[0055] In some embodiments, the controller includes an MCU chip and a MOS tube.

[0056] Exemplarily, the chip is an MCU (Microcontroller Unit) chip, and the controller further includes a MOS tube (Metal Oxide Semiconductor). The control electrode of the MOS tube is electrically connected to the MCU chip, and the two conducting ends of the MOS tube are electrically connected to the battery and the motor 311 respectively. The operation process is as follows: the user sends a power-on command to the MCU chip through the operation panel, and the MCU chip outputs a voltage to the control electrode of the MOS tube to turn on the MOS tube. At this time, the battery can supply power to the motor 311 through the MOS tube that has been turned on, so that the motor 311 starts to work. The user can continue to operate on the operation panel, and control the on-off frequency of the MOS tube by adjusting the size of the PWM duty cycle (i.e., pulse width modulation), and then adjust the battery supply voltage to the motor 311, thereby adjusting the speed of the motor 311. The higher the PWM duty cycle, the greater the voltage value of the power supply, and the higher the speed of the motor 311. The lower the PWM duty cycle, the lower the voltage value of the power supply, and the lower the speed of the motor 311. By setting the MCU chip and the MOS tube, the user can easily control the power supply voltage of the motor 311, thereby further improving the user experience.

To make the description concise, not all possible combinations of the technical features in the above-described embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0058] The above-described embodiments only express several implementation methods of the present application, and the descriptions thereof are relatively specific and detailed, but they cannot be construed as limiting the scope of the patent application. It should be pointed out that, for a person of ordinary skill in the art, several variations and improvements can be made without departing from the concept of the present application, and these all belong to the protection scope of the present application.
