DETAILED DESCRIPTION

[0028] The utility model is further described below in conjunction with the accompanying drawings and embodiments.

[0029] A typical implementation of the present utility model is as follows Figure 1-Figure 3 As shown, an internal connection structure of a heat-not-burn smoking device comprises a shell, wherein a cigarette clamp 7 for clamping a cigarette 1 is arranged inside the shell, and the cigarette clamp 7 comprises an inner shell 72 and an outer shell 71, wherein the outer shell 71 is sleeved on the outer side of the inner shell 72.

[0030] like Figure 5 As shown, the inner shell 72 includes a limiting section 721 and a accommodating cavity 722, and the limiting section 721 and the accommodating cavity 722 are arranged in an L shape. The accommodating cavity 722 is used to accommodate the cigarette 1, and a heating needle 6 is arranged therein, which can heat the cigarette 1 placed in the accommodating cavity 722. The shell includes an upper shell 3, and the upper shell 3 covers the cigarette clamp 7. The limiting section 721 is used to limit the upper shell 3.

[0031] Specifically, Figure 4 As shown, the limiting section 721 is provided with a mounting groove 724, and the mounting groove 724 is embedded with a magnet 723, and the top of the magnet 723 is arranged to protrude from the top of the limiting section 721 to ensure that the other matching parts are magnetically attracted. The upper shell 3 is provided with a magnetic material inside, and the magnetic material is arranged corresponding to the magnet 723. When the upper shell 3 and the cigarette clamp 7 are buckled with each other, the magnetic material and the magnet 723 are attracted to each other, so that the upper shell 3 and the cigarette clamp 7 are positioned by magnetic attraction, and the upper shell 3 and the cigarette clamp 7 are fixed.

[0032] A clamping structure is provided inside the upper shell 3, which can clamp the cigarette 1. When the upper shell 3 and the cigarette clamp 7 are buckled together, the cigarette 1 clamped by the upper shell 3 can enter the accommodating cavity 722 and contact the heating needle 6 located in the accommodating cavity 722, so that the cigarette 1 is heated by the heating needle 6.

[0033] Since the clamped cigarette 1 needs to be taken out when the upper shell 3 is separated from the inner shell 72, the holding force of the upper shell 3 on the cigarette 1 is greater than the clamping force of the inner shell 72 on the cigarette 1. In order to prevent the cigarette 1 from falling out of the accommodating cavity 722 during use, the snap fit between the upper shell 3 and the cigarette clamp 7 needs to be more stable to prevent displacement.

[0034] In order to solve the above problem, the limiting section 721 is further provided with a guide post 725 and a screw hole 726, and the guide post 725 and the screw hole 726 are respectively located on both sides of the mounting slot 724. Figure 6 As shown, the interior of the upper shell 3 is provided with inner holes 31 corresponding to the guide columns 725 and the screw holes 726 respectively. When the upper shell 3 is closed, the guide columns 725 and the screw holes 726 respectively cooperate with the corresponding inner holes 31, thereby further fixing the position of the upper shell 3 and ensuring the stability of the closing.

[0035] It is understandable that the guide column 725 and the screw hole 726 can be arranged at both ends of the limiting section 721, or can be located on the same side of the limiting section 721, and can be adjusted according to the specific internal structure.

[0036] A support frame 9 is also provided inside the outer shell 3. The support frame 9 is used to support the circuit board 8. The support frame 9 includes a connecting portion 91. The connecting portion 91 is located on one side of the inner shell 72. The connecting portion 91 is L-shaped and complementary to the structure of the inner shell 72. The inner shell 72 is detachably connected to the support frame 9 via the connecting portion 91.

[0037] The support frame 9 also includes a support portion 94, which is located below the connecting portion 91 and fixedly connected to the connecting portion 91. The circuit board 8 is a flexible component, and the circuit board 8 is wrapped around the outside of the support portion 94 after being folded. The support frame 9 supports the circuit board 8 through the support portion 94.

[0038] The outer shell 71 of the cigarette holder 7 is sleeved on the outer side of the inner shell 72, and the support frame 9 and the circuit board 8 are nested in the inner shell of the cigarette holder 7. When the outer shell 71 is buckled into the inner shell 72, it covers and protects part of the circuit board 8 and the support frame 9.

[0039] Since the circuit board 8 has a circuit laid on its surface after being folded, it is inconvenient to fix the portion of the support frame 9 parallel to the circuit to avoid damaging the circuit. Therefore, the support frame is fixed by the connecting portion 91 of the support frame 9 to fully utilize the space of the inner shell 72, thereby ensuring the space utilization inside the smoking device and making the installation structure between the support frame 9 and the circuit board 8 and the inner shell 72 of the cigarette holder 7 more compact.

[0040] In order to enhance the connection stability of the connecting part 91, the mounting groove 724 provided in the limiting section 721 is provided as a through hole structure, the magnet 723 is located in the mounting groove 724, and a protruding portion is provided in the direction of the support frame 9 through the mounting groove 724, and the connecting part 91 of the support frame 9 forms a fixing ring 911 which surrounds the magnet 723, and the fixing ring 911 clamps the magnet 723. On the one hand, it can enhance the stable embedding relationship between the connecting part 91 and the inner shell 72, and on the other hand, it can ensure the stability of the magnet 723 and enhance the magnetic attraction to the upper shell 3, while ensuring the minimization of the changes to the internal structure and the compactness of the internal structure while fixing it. Similarly, the inner side of the fixing ring 911 can also be made of magnetic attraction material to increase the clamping effect.

[0041] The circuit board 8 is a flexible part, which is folded and wrapped around the outside of the support frame 9. At the same time, the circuit board 8 is also provided with a circuit surface 81 for arranging circuits, and a mounting surface 82 abutting against the outside of the support plate. After the circuit board 8 is folded, the circuit surface 81 faces outward to avoid being squeezed with the support plate; the shell is provided with an upper shell 3 for clamping the cigarette 1 and a protective cover 2 for protecting the battery. The battery is located inside the protective cover 2. The circuit board 8 extends from the inner shell 72 to the outer shell 71 from the mounting position, abutting against the end face of the battery, but there is no overlap. The circuit board 8 is also provided with a charging port 5. The circuit board 8 and the battery are separated in the axial direction, and the charging port 5 is not in direct contact with the battery. When the outer shell 71 of the cigarette holder 7 is sleeved on the inner shell 72, part of the outer shell 71 can cover the battery; in addition, the smoking device is also provided with a motor 92, which is located in the inner shell In Fig. 72, the connecting portion 91 of the support frame 9 is provided with a paddle 93 and a ring member 912. The motor 92 is located below the paddle 93 and embedded in the support frame 9. The remaining space on the side of the inner shell 72 after the accommodating cavity 722 is formed is fully utilized, and the supporting frame 9, the circuit board 8 and the motor 92 are compactly arranged in the inner shell 72 with matching structures. In order to strengthen the firmness and stability of the motor fixation, a ring member 912 is added to the connecting portion 91. The ring member 912 at least partially surrounds the outside of the motor, so that the motor 92 and the connecting portion 91 form an embedded relationship, which plays a positioning role for the motor 92. The structure of the motor 92 in the inner shell 72 is more stable, the layout is more compact, and the assembly space is saved. The vibration of the motor 92 drives the paddle 93 to vibrate. The motor 92 is used for vibration prompts, mainly for prompts for the start or completion of suction.

[0042] like Figure 3As shown, the smoking device is provided with a button 4 for controlling the start and end of inhalation. The button 4 is located in the shell 71 and is arranged on the upper side of the battery shielding portion. The button 4 is fixed by arranging a button bracket 41 on the shell 71. The button bracket 41 is arranged above the circuit surface 81 of the circuit board 8 and is parallel to the circuit surface 81. At the same time, the button 4 needs to be at least partially protruded from the outermost side of the entire smoking device to ensure convenient and effective operation by the user. In addition to having a sleeve protection function for the battery, the protective cover 2 partially covers the shell 71 of the cigarette holder 7 during assembly. Therefore, a button accommodating opening is directly arranged at the position of the protective cover 2 relative to the button bracket 41. The button 4 is effectively matched with the button bracket 41 through the accommodating opening to ensure the practicality of the operation of the smoking device.
