Description

Heating non-combustible smoking set

Technical Field

The utility model relates to a smoking article, concretely relates to heating does not burn smoking set.

Background

The cigarette is not burnt by heating, and unlike the traditional cigarette, the low-temperature cigarette designed by taking the idea of 'not burning by heating' can ensure that the tobacco leaves are just heated to the degree of giving off the taste, and the tobacco leaves cannot be ignited. Generally, when ordinary cigarettes are smoked, a large number of harmful substances are generated at a high temperature of 350 ℃ to 600 ℃, and when low-temperature cigarettes are all below 300 ℃, the harmful substances are reduced. Specifically, taking the emissions as an example, heating a non-combustible tobacco product is only about 5% of conventional tobacco. From a cytotoxicity perspective, heating a non-combustible tobacco product is about 14% of a conventional cigarette.

In addition, the heating non-combustion product is closer to the traditional cigarette in taste and smoking experience, so that a smoker can feel the real tobacco taste and is more easily accepted.

As described above, in the heating of the nonflammable tobacco product, tobacco is heated by an external heat source instead of igniting the tobacco to generate a tobacco flavor gas, and there are methods such as char heating and electric heating. The method is characterized in that a special smoking set is required to be arranged for heating the non-burning tobacco products, the heating temperature and the heating time are accurately controlled, the heating and the non-burning can be realized, obviously, the special heating and the non-burning tobacco products are required to be provided with a more complex heating module, an energy module and a control module, and the volume of the smoking set is far larger than that of the traditional cigarette products. Intuitively, traditionally, the articles of smoking articles are in the range of tens of cigarettes to tens of cigarettes in a cigarette pack, while some cigarette packs also have a friction-lit configuration, which is very convenient to carry and store. And the heating incombustible goods on the present market, cigarette props up and puts in a cigarette case to because the heating principle, the humidity keeps handling to the cigarette case needs, to the smoking set of a cigarette heating when still needing the suction in addition, most products still dispose the box that charges specially, lead to needing great storage space, cause certain inconvenience for carrying.

In addition, as described above, the heating of the non-combustible smoking set requires a variety of functions, and different modules need to be arranged, so that the smoking set manufacturing process is complicated, and particularly, the assembly process is complicated, and is not suitable for the characteristics of large quantity of tobacco products and high requirement for industrialization degree.

The existing heating non-combustion smoking set generally comprises a rod-shaped structure and a box-packed structure. Compared with a box-shaped structure, the rod-shaped structure is popular with more and more consumers because of the advantages of small size, convenient holding, more accordance with the hand-held feeling of the traditional cigarette and the like. However, since the inner space of the rod-shaped structure is small, the axial size and the radial size of the rod-shaped structure are easily affected after integrating the structures such as the battery, the heating element, the smoke chamber and the like in the inner space of the rod-shaped structure.

Therefore, in the prior art, the flexible circuit board is adopted to assemble the smoking set which is not burnt during heating, and the space required in the smoking set is reduced. However, due to the flexible characteristics of the flexible circuit board, when the flexible circuit board is welded with a heating body and other structures or is arranged in a shell, the positioning precision cannot be ensured, automatic assembly is difficult to realize, and the assembly efficiency is reduced

The above description is included in the technical recognition scope of the inventors, and does not necessarily constitute the prior art.

Fig. 1 shows the usage of the heating non-combustion smoking set 100, the smoking set is internally provided with functional modules such as a heating element, an energy supply element, and a control element, and a cigarette C is inserted into one end of the smoking set and heated by the heating element at a specific temperature to generate aerosol for a user to smoke, so as to achieve a smoking experience.

In one embodiment, the innovation of the present invention in one aspect is described based on the structure shown in fig. 2 and 5, which comprises a battery 510, a heating body 410 and a circuit component, which is a commonly configured functional module for heating a non-combustible smoking set.

Wherein the circuit assembly includes a flexible substrate 110; a control circuit, a battery pad 1102, and a heater pad 1103 formed on the flexible substrate; the flexible substrate 110 may include a plurality of different circuit regions and signal transmission is achieved through conductive structures (not shown) on the surface of the flexible substrate. For convenience of description, the flexible substrate 110 is explained below as including two circuit regions, which are referred to as a first circuit region 1101 and a second circuit region 1104, respectively. According to a typical industrial design, the charging interface and the heating body are usually designed at both ends of the smoking set, so that the first circuit region 1101 and the second circuit region 1104 are disposed at positions near both ends, respectively, in the smoking set. The first circuit region 1101 may be an installation region of a charging circuit, and is connected to a USB charging interface, for example, for charging a battery when the smoking set is connected to an external power source. The second circuit region 1104 is a control circuit for controlling heating power, and is connected to the heater.

The flexible substrate 110 is connected to the battery 510 and the heater 410 through a battery solder 1102 and a heater solder 1103, respectively. The battery pads 1102 include anode pads and cathode pads for being welded to the anode and cathode of the battery 510, respectively. Heater pads 1103 are formed on second circuit area 1104 and connected to the control circuitry for soldering to heater 410. As shown in fig. 7, a hard substrate 610 attached to the second circuit region 1104 is disposed on the back surface of the second circuit region 1104. Of course, in addition to second circuit region 1104 and heater pads 1103 in second circuit region 1104, a rigid substrate (not shown in the figures) may also be provided on the back side of the area of first circuit region 1101 and cell pads 1102 on flexible substrate 110. Moreover, the shape of the rigid substrate 610 is not limited to the shape shown in the drawings, and any rigid substrate 610 capable of being attached to the second circuit region 1104 may be included in the embodiments of the present application. The surface of the flexible substrate 110 on which electronic components are provided is referred to as a front surface, and the surface on which electronic components are not provided is referred to as a back surface.

The rigid substrate 610 can enhance the rigidity of the local structure of the flexible substrate, so that the local structure of the flexible substrate, especially the portion provided with the control circuit and the welding spot, is a rigid structure, and the portion can be kept from bending change, thereby avoiding the damage or failure caused by the fact that the structure arranged on the front surface is pulled due to the bending of the substrate. Moreover, the rigid structure of the flexible substrate 110 is strengthened, so that the flexible substrate is more stable in moving, welding and assembling processes, and the subsequent automatic production process is more reliable.

By arranging the welding points on the flexible substrate 110 to connect the battery 510 and the heating body 410, the arrangement of wires is reduced, so that the extension length of the internal elements in the axial direction of the smoking set can be shortened, and the compactness of the whole structure is improved. In addition, in the structure of wire connection, if the limit is not increased, the elements connected with each other can swing freely; the parts are connected closely by welding points, and the parts form a relatively stable whole based on the flexible substrate 110, so that the modularization degree of a product is improved, and the complexity of a subsequent automatic assembly process is reduced.

In addition, each part of the components will form a relatively stable whole based on the flexible substrate 110, and can also be adapted to select an open-ended integrated housing as an external support, which further reduces the process complexity. Compared with a split type shell, the number of moulds for forming the shell and the split buckling or connecting process of the shell in the assembling process are reduced, and the related positioning and limiting processes are also reduced. Of course, the one-piece housing is only one preferred embodiment of the present application, and the following embodiments are only explained by taking the one-piece housing as an example, but the housings in the embodiments of the present application are not limited to be all one-piece housings.

In addition, as the internal structure of the smoking set becomes more compact while pursuing miniaturization of the smoking set, the heat generated by the heating body is more intensively distributed in the smoking set, and the most direct result is that, in the process of heating cigarettes, if the conducting wire is arranged in the smoking set, the temperature change of the heating element will influence the change of the conducting parameter of the conducting wire, thereby influencing the stability of the heating temperature control curve of the cigarettes, and possibly causing the instability of the smoking taste.

Based on the structure disclosed in the above embodiment, as shown in fig. 6, the smoking set further includes a shell 210, the shell 210 is selected to define a cylindrical cavity, and two ends of the shell 210 have openings for communicating the outside with the cylindrical cavity; the housing 210 is mainly used for supporting each element, specifically, the battery 510, the flexible substrate 110, and at least part of the heating body 410 are accommodated in the cylindrical cavity; the battery 510 and the flexible substrate 110 pass through the opening to enter the cylindrical cavity.

The above-mentioned structure form of forming the solder joints to directly connect the battery 510 and the flexible substrate 110 based on the flexible substrate 110 is particularly suitable for the structure of the cylindrical cavity entering through the end opening.

The specific manufacturing process mainly comprises the following steps: forming a control circuit, a battery pad 1102 and a heater pad 1103 on the flexible substrate 110; the flexible substrate 110 is respectively connected with the battery 510 and the heating body 410 through a battery welding point 1102 and a heating body welding point 1103 to form a heating module; the heating module is passed through the opening into the cylindrical cavity.

Preferably, the housing 210 is an integrally formed structure, and the cylindrical cavity is cylindrical in shape; the number of forming dies can be reduced by the aid of the integrally forming mode, the split mode of a buckling structure is avoided, and corresponding interfaces do not need to be machined or formed. And the cylinder shape is changeed the shaping, also can select multiple implementation, for example, accessible mould pressing mode forms the cavity, also can adopt the mode of post processing such as bore hole processing, in fact, as preferred implementation, seamless metal pipe or seamless composite material pipe can directly be chooseed for use to casing 210, under the prerequisite that satisfies the size requirement, directly at the section of fashioned tubular product intercepting fixed length, constitute the substrate of casing 210, other structures are processed out to rethread machining mode, this will reduce the cost of manufacture by a wide margin undoubtedly. Of course, the non-integrated housing 210 and the housing 210 with the cavity in the shape of diamond, oval, etc. can also achieve the functions of the embodiments of the present application, and the above-mentioned preferred housing is only one preferred embodiment among the various housings 210.

In one embodiment, the flexible substrate 110 has several bending portions that change the extending direction of the local flexible substrate. For example, as shown in fig. 3, the second circuit region 1104 includes a first control unit 1105 located right in the figure, the first control unit 1105 is disposed at an end portion of the flexible substrate 110, the bent portion includes a first bent portion 1106, and an extending direction of the end portion is changed by the first bent portion 1106 to form a U-shaped structure with an opening facing parallel to an extending direction of the battery 510. Of course, the U-shaped structure is only one preferable configuration, and any other structure may be included in the scope of the embodiments of the present application as long as the bending of the flexible substrate 110 by the first bending portion 1106 is implemented, for example, the opening is toward the battery 510 side, but the U-shaped structure is not formed, and the structure is similar to a V-shaped structure or a right-angle structure. After bending the second circuit region 1104, the second circuit region 1104 includes a protrusion formed at an end edge of the flexible substrate 110, at which a heater pad 1103 is formed.

Similarly, the bending portion may include a second bending portion 1107 and a third bending portion 1108, and the extending direction of the middle portion of the flexible substrate is changed by the second bending portion 1107 and the third bending portion 1108, so that the middle portion forms a U-shaped structure with an opening facing perpendicular to the extending direction of the battery 510, and covers both end surfaces or partial regions of both end surfaces of the battery 510, and also covers partial regions of one circumferential surface of the battery 510. Of course, the U-shaped structure is only a preferable configuration, and any other structure that is implemented by the second bending portion 1107 and the third bending portion 1108 to bend the flexible substrate 110, for example, a structure that has an upward opening but both sides are not perpendicular to the extending direction of the battery 510, may be included in the scope of the embodiments of the present application.

As shown in fig. 4, the extending direction of the middle portion of the flexible substrate 110 is changed by the second bending portion 1107 and the third bending portion 1108. The length of the flexible substrate along the axial extension direction of the battery 510 can be reduced by the bending part, and the flexible substrate and the battery 510 are directly and fixedly connected relatively, and the "relatively fixed" means that the two connection structures basically keep the relative positions unchanged, and a little shaking or swinging can be allowed, so that the structural connection of the flexible substrate and the battery 510 is realized while the electrical connection is realized, and the additional connection structure and connection process are reduced.

In one embodiment, as shown in fig. 6, a fixing bracket 310 connected to an end of the case by limiting one or more rigid substrates 610 is provided at one side of the case 210. And the fixing bracket 310 has a shape matching the cavity of the housing 210, i.e. has an outer circumferential surface matching the inner wall of the housing 210, for fixing the second circuit region 1104 in the cavity with respect to the housing 210.

In this way, during the assembly process, the end portion of the flexible substrate 110 may be directly fixed to the housing 210 through the fixing bracket 310, and it is considered that a stop structure or a limiting structure is formed on the surface of the fixing bracket 310 to cooperate with the housing 210, for example, a smooth protrusion is formed on the surface of the fixing bracket 310, and the housing 210 is formed with a limiting hole, and after the fixing bracket 310 is pushed into the cylindrical cavity defined by the housing 210, the protrusion reaches the limiting hole and forms a fastening structure with the limiting hole.

On the other hand, the fixing holder 310, the battery 510 and the heating body 410 are connected to the flexible substrate 110 to form an integral body extending in the axial direction of the battery 510, and enter the cylindrical cavity through the opening of the case 210. The above components can be integrated and then pushed into the cylindrical cavity, which simplifies the assembly process of the housing 210 and the internal components. In order to reduce the length of the flexible substrate 110 in the axial direction, the second circuit region 1104 may be offset toward the center of the cavity in a direction perpendicular to the flexible substrate 110. Here, the offset toward the center of the cavity means that the second circuit region 1104 is bent based on the first bent portion 1106 in the above embodiment, so that the outer end of the second circuit region 1104 is offset toward the center of the cavity. By bending the second circuit region 1104, the length of the flexible substrate 110 in the axial direction is reduced. Of course, the shape of the bent second circuit region 1104 may be various, which has been described in the above embodiments and will not be described herein again.

In one embodiment, as shown in figure 5, the smoking article further comprises an intermediate packaging member (not shown) that secures the flexible substrate 110 relative to the battery 510. In the above embodiment, when the integrated structure is pushed into the cavity, the flexible substrate 110 may be easily bent during the pushing process due to its own characteristics. Thus, the step of pushing into the cavity can be performed after the flexible substrate 110 is fixed relative to the battery 510 using an intermediate packaging member before pushing the integrated structure into the cavity. The flexible substrate 110 is more difficult to bend in the pushing process, and the probability of breakage of the product in the automatic production process is reduced. Wherein the intermediate package may be a heat shrinkable material. After the heat shrinkable material is inserted into the corresponding position, it is shrunk and fixed at the flexible substrate 110 and the battery 510 by heating. The intermediate package may also be a non-metallic hollow-structured intermediate housing having a smaller diameter than the housing 210, for example, a plastic or the like. After the flexible substrate is fixed by the plastic housing, the housing 210 may be fixed to the outer circumference of the middle housing. When the middle package is a plastic shell, the shell 210 can be customized according to different requirements of a user, and the user experience is improved.

In one embodiment, the second circuit region 1104 is provided with a circuit switch for controlling the on/off of the control circuit. The smoking set also comprises a switch triggering component, and the circuit switch is operated by triggering the component. The switch activating member may be a button 3101 provided on the fixing bracket 310. The button 3101 may alternatively be implemented as a tongue-shaped structure having elasticity formed on the fixing frame 310, and the trigger switch element is pressed inward, and in conjunction with the above, the fixing frame 310 is pushed into the housing 210, the housing 210 is provided with an opening to expose the button, or the housing 210 is provided with a structure to trigger the button to be pressed inward.

The embodiments in the present specification are described in a progressive manner, and the same and similar parts among the embodiments are referred to each other, and each embodiment focuses on the differences from the other embodiments.

The above description is only an example of the present application and is not intended to limit the present application. Various modifications and changes may occur to those skilled in the art. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present application should be included in the scope of the claims of the present application.
