DETAILED DESCRIPTION
[0027] The utility model is further described below in conjunction with the accompanying drawings and embodiments.
[0028] A typical implementation of the present utility model is as follows Figure 1-Figure 3 As shown, a heat-not-burn smoking device shell fixing structure includes a shell and a cigarette clamp 6 arranged in the shell to clamp the cigarette 1, the cigarette clamp 6 includes an inner shell 62 for accommodating the cigarette 1 and an outer shell 61 surrounding the inner shell 62; the cigarette clamp 6 also includes a circuit board 7 located inside the outer shell 61 and a support frame 8 supporting the circuit board 7, and the support frame 8 and the outer shell 61 are connected by a limit assembly.
[0029] The limiting assembly includes a limiting groove 611 and a limiting protrusion 81, wherein the limiting groove 611 is arranged on the side wall of the outer shell 61, and the limiting protrusion 81 is arranged on the side wall of the support frame 8. The limiting groove 611 and the limiting protrusion 81 are respectively located in the outer shell 61 and the support frame 8 itself, and are formed integrally with the outer shell 61 and the support frame 8.
[0030] The limiting groove 611 is formed by the inward depression of the side wall of the shell 61, and is an arc-shaped opening surrounding the side wall of the shell 61. The limiting protrusion 81 is an arc-shaped boss formed by the side wall of the support frame 8 protruding outward. The limiting groove 611 and the limiting protrusion 81 are correspondingly arranged.
[0031] It is understandable that the above embodiment only provides an optimized structure for the position and shape of the limiting protrusion 81 and the limiting groove 611. In actual production, the specific position and shape of the limiting protrusion 81 and the limiting groove 611 are not limited, as long as the two form a limiting fit in a simple form.
[0032] In another embodiment, a limiting protrusion 81 is formed on the outer shell 61, and a limiting groove 611 is formed on the support frame 8 (not specifically shown in the figure). The limiting protrusion 81 is a protrusion formed by extending the outer shell 61 inward. Since the outer shell 61 is to wrap the internal structure of the cigarette holder 6, the interior of the outer shell 61 is hollow. The limiting protrusion 81 formed inward will not affect the structure of the outer shell 61 itself, and the limiting groove 611 is arranged on the support frame 8. The main function of the support frame 8 is to provide positioning support for the circuit board 7. Therefore, the structure of the support frame 8 is not complicated. While the support frame 8 plays a supporting role, an inward-recessed limiting groove 611 can be provided on the side wall of the support frame 8 to cooperate with the limiting protrusion 81, under the premise of ensuring that the support frame 8 can be placed in the space of the inner shell 62.
[0033] The shapes of the limiting groove 611 and the limiting protrusion 81 can be set in various ways. For example, the outer shell 61 forms a limiting protrusion 81 with a rectangular structure inward, and the support frame 8 forms a rectangular limiting groove 611 inward that is adapted to the limiting protrusion 81. It is sufficient as long as the structures of the limiting protrusion 81 and the limiting groove 611 are accurately matched.
[0034] like Figure 2 As shown, the smoking device also includes a battery and a circuit board 7. The cigarette holder is provided with a receiving cavity 612 for receiving cigarettes. The circuit board 7 is located below the receiving cavity 612, and the circuit board 7 has an extension section, which extends upward to a part of the circuit board 7 and a part of the inner shell 62 forming the receiving cavity 612 in the same plane.
[0035] The shape of the accommodating cavity 612 conforms to the shape of the cigarette 1. It can be understood that the accommodating cavity 612 does not have to be completely the same as the shape or inner diameter of the cigarette 1. As long as the accommodating cavity 612 can at least partially accommodate the cigarette 1, the cigarette 1 can contact the side wall of the inner shell 62 forming the accommodating cavity 612. When the diameter of the accommodating cavity 612 is larger than that of the cigarette 1, the cigarette 1 does not contact the inner wall of the inner shell 62 in the accommodating cavity 612, and the inner shell 62 plays a role in clamping and accommodating the cigarette.
[0036] The circuit board 7 is configured as a flexible member, which surrounds the outer side of the support frame 8 after folding to ensure the flatness of the outer circuit surface. In order to enhance the stability of the circuit board 7 and the support frame 8, a connecting portion can be provided on one side of the top of the support frame 8. The connecting portion is provided on one side of the accommodating cavity, and the top of the connecting portion is detachably connected to the inner shell, thereby strengthening the fixation of the support frame 8 to strengthen the position limitation of the circuit board 7.
[0037] The battery is located below the cigarette holder 6, and the circuit board 7 extends from the inner shell 62 to the outer shell 61 until it contacts the top of the battery through the conductive ear. After the circuit board 7 is folded, it is located outside the support frame 8, and the circuit board 7 is distributed on the side facing outward. The battery conductive ear is located at the folded part of the circuit board 7 and abuts against the battery. One end of the conductive ear abuts against the battery, and the other end is bent and adheres to the circuit board 7 at the folded part of the circuit board 7 and is welded to the circuit board 7, so that there is no overlapping part between the battery and the circuit board 7, while the connection relationship between the battery and the circuit board 7 can be guaranteed.
[0038] In order to protect the internal structure as much as possible in a limited space, Figure 3 As shown, lugs 613 are arranged on two planes of the outer shell 61. The lugs 613 are arranged in an elliptical shape. The lugs 613 are located above the connection between the battery and the circuit board 7, covering part of the circuit board 7 and part of the battery, so that the outer shell 61 can directly clamp the battery and the circuit board 7 on the outside.
[0039] At the same time, the outer shell 62 is provided with a lug 613 located above the conductive lug of the battery, partially covering the conductive lug along the width direction, which can shield the conductive lug and protect the conductive lug. The stability of the battery determines the service life of the smoking device. The conductive lug of the battery plays a key role in the battery storage capacity and the stability of the battery's endurance. It is a necessary condition to ensure that the connectivity at the conductive lug is not damaged. The lug 613 of the outer shell 62 can shield the conductive lug of the battery while clamping the battery and the circuit board 7 to prevent the conductive lug from being affected by the external environment. The conductive lug is at the folding position of the battery and the circuit board 7, which can better stably connect the battery and the circuit board 7 to avoid connection disorder.
[0040] The circuit board 7 is also provided with a charging interface 4, which is located on the side of the support frame. Since the battery and the circuit board 7 have no overlapping parts, the battery is not directly connected to the charging interface 4, which optimizes the battery layout and makes replacement more convenient.
[0041] like Figure 4 and Figure 5As shown, the smoking device also includes a cigarette 1 and a heating needle 5. The smoking device is provided with an upper shell 2 that cooperates with a cigarette clamp 6. The upper shell 2 is provided with a through hole 21 for the cigarette 1 to pass through. The cigarette clamp 6 is provided with an opening 63 for the cigarette 1 to extend into. A receiving cavity 612 for receiving the cigarette 1 is formed along the opening 63. The heating needle 5 is located in the receiving cavity 612 to heat the cigarette 1. The upper shell 2 is detachably connected to the cigarette clamp 6 and can be fixed after connection by a magnet or a stopper. The through hole 21 of the upper shell 2 is tightly matched with the cigarette 1. It has a clamping effect on the cigarette 1. The cigarette 1 passes through the through hole 21, and the lower end extends into the accommodating cavity 612, and is connected to the heating needle 5 fixed in the accommodating cavity 612. In this way, the heating needle 5 heats the cigarette 1. In order to ensure that the cigarette 1 is smoothly lifted up when the upper shell 2 is lifted from the inner shell 62 of the cigarette clamp 6, the opening size of the accommodating cavity 612 for the cigarette 1 to extend into is set to be wider than the size of the cigarette 1. Since the upper shell 2 clamps the cigarette 1 tightly, the cigarette 1 can be smoothly lifted up by the upper shell 2.
[0042] The smoking device is provided with a button 3 to control the start and stop of heating, and the button 3 is located on the shell 61. The smoking device is also provided with a protective shell for protecting the battery and the shell 61 of the cigarette holder 6. The button 3 needs to be placed on the outermost side so that the user can operate it directly. Therefore, in order to fix the button 3, a fixing structure matching the button 3 is provided on the protective shell, which can be in the form of a groove or other forms. In the present embodiment, the specific position of the button 3 is above the circuit board blocked by the shell 61. In order to ensure the operating effect of the button 3, the shell 61 is provided with a hollow bracket 31 located at the circuit board 7. When the hollow bracket 31 is provided, a part of the shell 61 can be retained as a card-in slot for the button 3. The shape and structure of the card-in slot are adapted to the button 3. This further improves the fixation of the button 3 when it is inserted. The button 3 is installed at the hollow bracket 31. The button 3 and a lug 613 of the shell 61 are located on the same side. The lug 613 and the hollow bracket 31 are arranged along the same axis in the axial direction. The lug is formed at the end of the lower part of the shell 61 and is arranged to be an arc-shaped structure extending downward. It is located below the hollow bracket 31 to clamp the battery and the circuit board 7. At the same time, the shell 61 is provided with an arc-shaped boundary. At the position of the arc-shaped boundary, the upper part cooperates with the upper shell 2, and the edge of the upper shell 2 is arranged to be an arc-shaped end face that cooperates with the arc-shaped boundary. When the cover is closed, it is buckled with the arc-shaped boundary. The hollow bracket 31 is arranged at the lower part of the arc-shaped boundary and is arranged to be elastically matched with the button 3 to adapt to user operation.
[0043] The above description is only the preferred embodiment of the utility model, and is not intended to limit the utility model. For those skilled in the art, the utility model can have various modifications and changes. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the utility model shall be included in the protection scope of the utility model.
