Description

Technical Field

[0001] The utility model relates to the technical field of smoking articles, in particular to a heat-not-burn smoking article. Background Art

[0002] Relevant studies have shown that ordinary cigarettes will produce many harmful substances at high temperatures of 350°C to 600°C when smoked, while low-temperature cigarettes are all below 300°C, and the harmful substances will be reduced. Specifically, taking the release as an example, the release of heat-not-burn tobacco products is only about 5% of traditional tobacco. From the perspective of cytotoxicity, heat-not-burn tobacco products are about 14% of traditional cigarettes. Heat-not-burn cigarettes are different from ordinary cigarettes. "Low-temperature cigarettes" designed with the idea of ​​"heating without burning" can heat the tobacco leaves just enough to emit flavor without igniting the tobacco leaves.

[0003] Heat-not-burn tobacco products use external heat sources to heat tobacco instead of burning it to produce tobacco flavor gas, and there are charcoal heating, electric heating and other methods. Crucially, heat-not-burn tobacco products need to be equipped with special smoking utensils to more accurately control the heating temperature and time, so that "heating without burning" can be achieved. Obviously, special heat-not-burn smoking utensils need to be equipped with more complex heating modules, energy modules and control modules, so the volume of the cigarette is much larger than that of traditional cigarette products. Intuitively described, according to regulations, traditional cigarette products are placed in cigarette boxes with dozens of cigarettes, and some cigarette boxes also have friction ignition configurations, which are very convenient for carrying and storage. However, in the heat-not-burn products on the market now, cigarettes are placed in a cigarette box, and due to the heating principle, the cigarette box needs to be treated with humidity maintenance. In addition, smoking utensils are required to heat the cigarettes when smoking. Most products are also specially equipped with charging boxes, resulting in the need for a larger storage space, which causes certain inconveniences to carry. In the prior art, the control circuit is placed in the middle of the smoking device, while the charging circuit is placed at the bottom of the smoking device, which causes the smoking device to occupy too much space and form complex connections during structural design.

[0004] Since heat-not-burn smoking devices have many functions to realize and need to be configured with different modules, the manufacturing process of smoking devices is also relatively complicated, especially the numerous assembly processes, which is not compatible with the characteristics of tobacco products with large volume and high industrialization requirements. How to reduce the size of smoking devices and realize the miniaturization and portability of smoking devices is a topic that technicians in this field are constantly studying. Utility Model Content

[0011] As a further technical solution, the shell has a battery accommodating cavity inside, and the battery is arranged in the battery accommodating cavity.

[0012] As a further technical solution, a support block is provided at the bottom of the battery accommodating cavity, one end of the support block cooperates with the bottom of the battery accommodating cavity, and the other end of the support block cooperates with the bottom of the battery.

[0013] As a further technical solution, the battery accommodating cavity and the battery are both columnar, and the side wall of the battery has a shape that is compatible with the side wall of the battery accommodating cavity.

[0014] As a further technical solution, the circuit assembly further includes a charging interface connected to the flexible circuit board, and the charging interface is arranged between the first circuit area and the second circuit area.

[0015] As a further technical solution, a reinforcement layer is provided on the side of the first circuit area and the second circuit area facing the charging interface.

[0016] As a further technical solution, the battery comprises a positive electrode ear and a negative electrode ear respectively led out from one end of the battery, and the positive electrode ear is welded and fixed to the positive electrode connector, and the negative electrode ear is welded and fixed to the negative electrode connector.

[0017] As a further technical solution, the positive electrode connector and the negative electrode connector are arranged on a side of the first circuit region or the second circuit region facing the battery.

[0018] As a further technical solution, the support member is bonded and fixed to the first circuit area and the second circuit area, and the support member also has an assembly groove that can accommodate the charging interface.

[0019] One or more technical solutions of the utility model have the following beneficial effects:

[0020] 1. Compared with the prior art in which the circuit board is wrapped around the battery, the heat-not-burn smoking device provided by the utility model can greatly reduce the radial size of the battery and circuit board assembly, and can avoid or greatly reduce the impact of the heat generated by the battery during operation on the normal operation of the circuit board.

DETAILED DESCRIPTION

[0034] It should be noted that the following detailed descriptions are all illustrative and are intended to provide further explanation of the present invention. Unless otherwise specified, all technical and scientific terms used in the present invention have the same meanings as those commonly understood by those skilled in the art to which the present invention belongs.

[0035] Embodiment 1

[0036] like Figure 1-7 As shown, the utility model provides a heat-not-burn smoking device, comprising: a shell 1, a circuit assembly and a supporting member 3, the circuit assembly and the supporting member 3 are arranged inside the shell 1, the circuit assembly comprises a battery 4 and a flexible circuit board 2 arranged at one end of the battery and connected to the battery, the flexible circuit board 2 is an overall "U"-shaped structure, the opening of the flexible circuit board 2 is arranged at an end away from the battery 4, the bent portion thereof is arranged close to the battery 4, and a positive terminal 24 and a negative terminal 25 connected to the battery are arranged at the end close to the battery. Compared with the smoking device in which the circuit board is wrapped around the battery, the structure provided by this embodiment can greatly reduce the radial size of the battery 4 and the circuit board assembly, and can avoid or greatly reduce the influence of the heat generated by the battery 4 during operation on the normal operation of the circuit board.

[0037] The support member 3 is arranged along the axial direction of the battery 4 , one end of the support member 3 is arranged close to the battery 4 , and the other end extends away from the battery 4 , and the flexible circuit board 2 is bent into a "U"-shaped structure along the side of the support member 3 .

[0038] In addition, through the structure introduced above, the battery 4 and the circuit components in the utility model are arranged sequentially in the axial direction. Compared with the method of arranging the battery 4 and circuit components such as the circuit board side by side in the axial direction in the prior art, the above structure is more convenient and quick during the assembly, maintenance and disassembly process, which is beneficial to improving the assembly efficiency and is beneficial to the modular design and production of the smoking device.

[0039] In this embodiment, the flexible circuit board 2 includes a first circuit area 21, a second circuit area 22, and a connection area 23 connecting the first circuit area 21 and the second circuit area 22. The first circuit area is provided with a switch, an indicator light, a power supply, etc., and the second circuit area is provided with MCU control, charging, etc.; the connection area 23 is provided between the support member 3 and the battery 4, the first circuit area 21 and the second circuit area 22 are bent relative to the connection area 23 in a direction away from the battery 4 to form a "U"-shaped structure, and the connection area 23 abuts against one end of the battery 4 or the connection area 23 is provided close to one end of the battery 4. The positive terminal 24 and the negative terminal 25 are provided in the first circuit area. Since the flexible circuit board 2 is in a "U"-shaped structure, it can complement the other components inside the housing 1 in the installation space, thereby avoiding occupying too much installation space in the axial dimension, resulting in the axial dimension of the entire smoking device being too large, which is ultimately conducive to the miniaturization of the smoking device.

[0040] In this embodiment, the housing 1 has a battery receiving chamber with one end closed, and the battery 4 is arranged in the battery receiving chamber. The side wall of the battery 4 has a shape adapted to the side wall of the battery receiving chamber. In addition, a support block is arranged at the bottom of the battery receiving chamber, one end of the support block matches the bottom of the receiving chamber, and the other end matches the bottom of the battery 4. The above structure enables the battery 4 to be stably assembled in the housing 1, and the matching of the side wall of the battery 4 with the side wall of the battery receiving chamber is conducive to making full use of the installation space inside the housing 1, reducing the radial dimensions of the battery 4 and the housing 1, and facilitating the miniaturization of the smoking device.

[0041] In this embodiment, the housing 1 is an integral structure, and the battery receiving cavity and the battery 4 are both cylindrical, or as shown in FIG. Figure 5 As shown, the housing 1, the battery accommodating cavity and the battery 4 are all in a flat column shape. Compared with the standard cylindrical structure, this structure increases the width but also provides a better grip for the user. The flat round end face is more convenient to use the installation space on the surface than the standard circular end face, which facilitates the assembly and matching of the battery 4 and the circuit components.

[0042] In addition, the one-piece molding method can reduce the number of molding molds and avoid the split method of the snap-fit ​​structure, so there is no need to process or form the corresponding interface. Moreover, the columnar shape is easier to form, and a variety of implementation methods can be selected. For example, the cavity can be formed by molding, or post-processing such as boring can be used. In fact, as a preferred implementation method, the shell can directly use seamless metal tubes or seamless composite tubes. Under the premise of meeting the size requirements, a fixed length of segment is directly cut from the molded tube to form the base material of the shell, and then other structures are processed by machining, which will undoubtedly greatly reduce the production cost.

[0043] In this embodiment, the circuit assembly further includes a charging interface 5 connected to the flexible circuit board 2, and the charging interface 5 is arranged between the first circuit area 21 and the second circuit area 22. A reinforcing layer 26 is arranged on the side of the first circuit area 21 and / or the second circuit area 22 facing the charging interface 5. The reinforcing layer 26 can strengthen the rigidity of the local structure of the flexible circuit board 2, and can make the local structure of the flexible circuit board 2, especially the part where the positive terminal 24 and the negative terminal 25 are arranged, a rigid structure, and can keep the front of the part from bending and changing, so as to avoid the structure arranged on the front from being pulled due to the bending of the flexible circuit board 2, causing damage or failure.

[0044] In this embodiment, the battery 4 includes a positive electrode ear 41 and a negative electrode ear 42 respectively extending from one end of the battery 4, the positive electrode connector 24 is welded and fixed to the positive electrode ear 41, and the negative electrode connector 25 is welded and fixed to the negative electrode ear 42, wherein the positive electrode connector 24 and the negative electrode connector 25 are arranged on the side of the first circuit area 21 or the second circuit area 22 facing the battery 4.

[0045] In this embodiment, the first circuit area 21 and the second circuit area 22 are bent relative to the connection area 23 along the side of the support member 3; the first circuit area 21 and / or the second circuit area 22 are bonded and fixed to the support member 3, and the support member 3 has an assembly groove 31 that can accommodate the charging interface 5. The flexible circuit board 2 can be fixed relative to the battery 4 by the setting of the support member 3. When the overall structure is pushed into the shell 1, due to the characteristics of the flexible circuit board 2 itself, it is easy to bend during the pushing process. Therefore, before the overall structure is pushed into the cavity, the support member 3 can be used to fix the flexible circuit board 2 relative to the battery 4, and then the step of pushing into the cavity is performed. It can ensure that the flexible circuit board 2 is more difficult to bend during the pushing process, and the probability of product damage during the automated production process is reduced. Among them, the support member 3 can be a heat shrinkable material. After the heat shrinkable material is inserted into the corresponding position, it is shrunk and fixed at the flexible circuit board 2 and the battery 4 by heating. The support member 3 can also be a non-metallic hollow structure intermediate shell 1 with a diameter smaller than the shell 1, such as a plastic product. After the flexible substrate is fixed by the plastic housing 1, the housing 1 can be fixed to the outer periphery of the intermediate housing 1. When the supporting member 3 is a plastic housing 1, the housing 1 can be customized according to different requirements of users to enhance user experience.

[0046] Moreover, each component will form a relatively stable whole based on the flexible circuit board 2 and the supporting member 3, and can also adapt to the selection of an integrated housing 1 with an open end as an external support, which will further reduce the complexity of the process. Compared with the split housing 1, the number of molds for forming the housing 1 and the process of split buckling or connecting the housing 1 during the assembly process are reduced, and the related positioning and limiting processes are also reduced.

[0047] The above description is only a preferred embodiment of the utility model and is not intended to limit the utility model. For those skilled in the art, the utility model may 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.
