Description

Technical Field

[0001] The present invention belongs to the field of smoking devices, and specifically relates to a tobacco holder for a low-temperature smoking device, a low-temperature smoking device provided with the above tobacco holder, and a low-temperature smoking device assembly.

Background Art

[0002] According to relevant research, the combustion temperature of conventional rolled tobacco is 800°C or higher. During the combustion process of rolled tobacco, more than 5,000 kinds of chemical substances are generated, of which more than 80 are carcinogenic chemical substances, indicating that the smoke generated thereby poses a very great harm to non-smokers. The non-combustion heating technology directly heats an aerosol substrate (also called non-combustion heated tobacco) by a low-temperature smoking device without combustion to generate smoke. The harmful substances generated by such a heating method are significantly reduced compared with the harmful substances generated by burning conventional tobacco, and can meet the needs of consumers while reducing the harm to the body.

[0003] The main device of the non-combustion heating technology is a low-temperature smoking device. The low-temperature smoking device generates a pyrolysis reaction by heating an aerosol substrate, and heats the tobacco material in the aerosol substrate to a sufficient degree to produce a tobacco flavor and smoke for the user to inhale.

[0004] Conventional low-temperature smoking devices have a tobacco clamping hole for clamping an aerosol substrate. The heating element installed in the tobacco clamping hole is inserted into the aerosol substrate to realize heating of the aerosol substrate. At present, there are various different types of aerosol substrates on the market, so the aerosol substrates have different lengths and diameters, and thus, different apertures and depths of tobacco clamping holes compatible with the aerosol substrates are required. The aperture and depth of the tobacco clamping hole of the conventional low-temperature smoking device are difficult to change, and generally can only be compatible with one type of model number of aerosol substrate, the use effect is limited, it is difficult to meet the use needs of users, and the compatibility is not high.

[0005] In addition, to be compatible with aerosol substrates of different model numbers, correspondingly different heater structures are required. Conventional low-temperature smoking devices generally use a ceramic sheet as a heater to achieve heating of the aerosol substrate. The cost of the ceramic sheet is high, and its structure is easily damaged. Generally, users need to operate carefully each time they insert and remove the aerosol substrate. Therefore, due to the conventional heater structure, it is not suitable for the conventional low-temperature smoking device to be modified into a product with good compatibility.

Summary of the Invention

Problems to be Solved by the Invention

[0006] One object of the present invention is to provide a tobacco holder for a low-temperature smoking device, by which the compatibility between the heater and the aerosol substrate is improved. Another object of the present invention is to provide a low-temperature smoking device provided with the above-mentioned tobacco holder. A further object of the present invention is to provide a low-temperature smoking device assembly provided with a set of the above-mentioned tobacco holders.

Means for Solving the Problems

[0007] The present invention provides a tobacco holder for a low-temperature smoking device. The low-temperature smoking device includes a smoking device body and a heating element. The tobacco holder includes a tobacco clamping housing and a heat conduction cover. The tobacco clamping housing is removably assembled to the smoking device body. A tobacco clamping hole is formed in the tobacco clamping housing for positioning an aerosol substrate. The heat conduction cover is provided on the tobacco clamping housing. The heating element can be inserted into the open end of the heat conduction cover, and the aerosol substrate can be inserted into the closed end of the heat conduction cover. Thus, the heating element can heat the aerosol substrate through the heat conduction cover. The tobacco holder is assembled to the smoking device body, and an aerosol substrate for generating smoke is provided in the tobacco clamping hole. The tobacco holder realizes the connection between the aerosol substrate and the smoking device body. The heating element is inserted into the heat conduction cover to heat the aerosol substrate, thereby changing the heat conduction method between the heating element and the aerosol substrate, preventing mutual influence between the heating element and the aerosol substrate, and improving the compatibility between the heating element and the aerosol substrate.

[0008] In an exemplary embodiment of the tobacco holder of the low-temperature smoking device, the smoking device body includes a heating element. After the tobacco holder is assembled to the smoking device body, the heating element can be inserted into the heat conduction cover through the open end.

[0009] In an exemplary embodiment of the tobacco holder of the low-temperature smoking device, the tobacco holder includes a heating element fixed to the tobacco clamping housing. The heating element is provided on the tobacco holder, matches the dimensions of the heat conduction cover, and the heat generated by the heating element can be quickly transmitted to the heat conduction cover, improving the comfort during suction.

[0010] In an exemplary embodiment of the tobacco holder of the low-temperature smoking device, the tobacco holder further includes a conductive member. The conductive member can be electrically connected to the heating element. After the tobacco holder is assembled to the smoking device body, it can be electrically connected to the smoking device body through the conductive member.

[0011] In an exemplary embodiment of the tobacco holder of the low-temperature smoking device, the heating element is a heating pin that can extend along the axial direction of the tobacco clamping hole. The heating pin can be quickly inserted into the heat conduction cover. The extending direction of the heating pin is the axial direction of the tobacco clamping hole. When the aerosol substrate is positioned by passing through the tobacco clamping hole, the aerosol substrate is also positioned in the tobacco clamping hole by following the axial direction of the heating hole. The heating pin can uniformly heat the aerosol substrate.

[0012] In an exemplary embodiment of the tobacco holder of the low-temperature smoking device, the heat conduction cover is a conical cover. The conical cover facilitates the insertion of the heating element and enables the aerosol substrate to be quickly inserted.

[0013] In an exemplary embodiment of the tobacco holder of the low-temperature smoking device, the tobacco clamping housing is provided with a heat insulation section along the depth direction of the tobacco clamping hole, and the heat conduction cover is located within the heat insulation section along the depth direction. The heat insulation section can prevent the heating element from transmitting heat to the main body of the smoking device during heating and burning the user.

[0014] In an exemplary embodiment of the tobacco holder of the low-temperature smoking device, the tobacco clamping housing further includes a mounting cap section along the depth direction. The tobacco clamping hole is opened in the mounting cap section. A step portion is provided between the mounting cap section and the heat insulation section. The heat insulation section can be inserted into the insertion hole of the main body of the smoking device, and the step portion can be locked to the insertion hole opening of the main body of the smoking device. By connecting to the main body of the smoking device through the fitting between the mounting cap section, the step portion, and the heat insulation section, the tobacco clamping housing can be closely connected to the main body of the smoking device.

[0015] The present invention further provides a low-temperature smoking device including the main body of the smoking device and the above-mentioned tobacco holder. The main body of the smoking device is provided with an assembly end. The tobacco clamping housing is removably assembled to the assembly end of the main body of the smoking device. The aerosol substrate can be inserted into the closed end of the heat conduction cover.

[0016] The present invention further provides a low-temperature smoking device assembly comprising a smoking device body and a set of the above-mentioned tobacco holders. The smoking device body has an assembly end, and the tobacco clamping housing of each tobacco holder is removably assembled to the assembly end of the smoking device body. The depth and / or aperture diameter of the tobacco clamping holes of each tobacco clamping housing are different from each other, and an aerosol substrate can be inserted into the closed end of each heat conduction cover. Since the depth and / or aperture diameter of the tobacco clamping holes of the tobacco clamping housing are different from each other, different types of tobacco holders can satisfy the dimensions of most aerosol substrates, and each tobacco holder can be assembled with the smoking device body. Therefore, by connecting the smoking device body and the aerosol substrate through the tobacco holder, the compatibility of the smoking device body is improved, so that the needs can be satisfied according to one smoking device body, and the cost is reduced.

Embodiments for Carrying out the Invention

[0018] The following clearly and completely describes the technical solutions in the embodiments of the present invention with reference to the drawings in the embodiments of the present invention. Obviously, the described embodiments are only some embodiments of the present invention, not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative efforts belong to the patent scope of the present invention.

[0019] It should be noted that the terms for directions such as left, right, up, down, front, and back in the embodiments of the present invention are only relative concepts to each other or are based on the normal use state of the product, that is, the advancing direction of the product, and should not be considered limiting.

[0020] Furthermore, it should be further noted that the dynamic terms such as "relative movement" mentioned in the embodiments of the present invention include not only the change in position but also the movement in which the state changes although there is no relative change in position such as rotation and rolling.

[0021] Finally, it should be noted that when an assembly is said to "be located in" or "be provided in" another assembly, it may be in another assembly or a central assembly may exist simultaneously. When an assembly is said to "be connected to" another assembly, it may be directly connected to another assembly or a central assembly may exist simultaneously.

[0022] In the present invention, unless otherwise specified, all aerosol substrates are non-combustible heated cigarettes.

[0023] FIG. 1 is a schematic structural view of an exemplary embodiment of a tobacco holder of a low-temperature smoking device and a schematic exploded structural view of an exemplary embodiment of the low-temperature smoking device. FIG. 2 is a schematic structural view after combining the low-temperature smoking devices in FIG. 1. As shown in FIG. 1, the low-temperature smoking device includes a smoking device main body 20 and a tobacco holder 10. Here, as shown by the solid-line part in the figure, the tobacco holder 10 includes a tobacco clamping housing 12, and the tobacco clamping housing 12 is detachably assembled to the smoking device main body 20 along the connecting line of the broken line in the figure. The assembly structure may also refer to FIG. 2 at the same time. Further, a tobacco clamping hole 122 for positioning the aerosol matrix 30 is formed in the tobacco clamping housing 12, and the aerosol matrix 30 can be inserted into the tobacco clamping hole 122. The insertion state may also refer to FIG. 2 at the same time.

[0024] FIG. 3 is a schematic cross-sectional structural view of an exemplary embodiment of a tobacco holder of a low-temperature smoking device and a schematic exploded view of a local structure of an exemplary embodiment of the low-temperature smoking device. FIG. 4 illustrates a schematic structural view after combining the local structures of the low-temperature smoking device in FIG. 3. As shown in FIGS. 3 and 4, the low-temperature smoking device further includes a heating element 22, and the heating element 22 shown in the figure is provided on the smoking device main body. As shown by the solid-line part in FIG. 3, the tobacco holder 10 further includes a heat conduction cover 16, and the heat conduction cover 16 is provided on the tobacco clamping housing 12. The heat conduction cover 16 includes an open end 162 and a closed end 164 opposite to the open end 162. The heating element 22 can be inserted into the open end 162 of the heat conduction cover 16, and the aerosol matrix 30 can be inserted into the closed end 164 of the heat conduction cover 16, so that the heating element 22 can heat the aerosol matrix 30 through the heat conduction cover 16.

[0025] The different tobacco holders 10 can have different depths and pore diameters, so that different tobacco holders 10 can be adapted to different types of aerosol substrates. At the same time, to adapt to different depths and pore diameters, that is, to different types of aerosol substrates, different-sized or differently-modeled heat conduction covers are correspondingly attached to the tobacco holders 10. The user can arrange a plurality of the above-mentioned tobacco holders and select according to actual use, improving the compatibility of the use of the low-temperature smoking device.

[0026] After replacing the heating body structure of the conventional type of ceramic chip with a heating structure combined with a heat conduction cover, the heating area for heating the aerosol substrate is determined by the size of the heat conduction cover, and the heating effect and use effect are affected by the shape of the heat conduction cover. As can be seen, by the method of combining the heat conduction cover, the requirements for the structure of the heating body itself can be reduced. For example, heating body structures with relatively high costs can be mass-produced in a standardized manner, and then different-sized or differently-modeled heat conduction covers with relatively low costs can be matched. Also, the heating effect and use effect of the heating body can be expanded. For example, in the embodiments shown in FIGS. 3 and 4, the heat conduction cover 16 may adopt a conical cover. The conical cover can improve the heating angle and increase the heating area. Also, during the insertion and extraction process of the aerosol substrate, the frictional force between the tobacco leaves in the aerosol substrate can be reduced, preventing the tobacco leaves from remaining on the heat transfer cover.

[0027] In the embodiment shown in FIG. 3, the smoking device main body 20 includes the heating element 22, the tobacco holder 10 is assembled to the smoking device main body 20, and the heating element 22 can be inserted into the heat conduction cover 16 through the open end 162. As described above, after adopting the heating structure combined with the heat conduction cover, in order to make the heating structure conform to different types of aerosol substrates by changing the model number or dimensions of the heat conduction cover, the tobacco holder 10 may not include the heating element 22, and the heating element 22 may be located in the smoking device main body 20. In such a manner, the structure of the tobacco holder 10 can be simplified, the manufacturing cost of the tobacco holder can be significantly reduced, and the tobacco holder 10 can meet the compatibility requirement only by matching different heat conduction covers. In this way, when the user has a smoking device main body with a heating element, the user only needs to select a tobacco holder that matches different model numbers of heat conduction covers as needed. Since the cost of the tobacco holder with the above structure is low, the user intends to have more model numbers of the above tobacco holders.

[0028] Also, since the tobacco holder 10 does not include the heating element 22, the tobacco holder 10 itself can be used as a tobacco extractor. The tobacco extractor is a device for helping to remove the aerosol substrate 30, thereby preventing the tobacco leaves in the aerosol substrate 30 from remaining on the heating element 22. Since the heating element itself is generally heated by conduction, it is inconvenient during cleaning. The entire aerosol substrate 30 may be taken out using the tobacco extractor. As shown in FIGS. 3 and 4, since the heat conduction cover 16 is provided to cover the heating element 22, the heating element 22 does not directly contact the tobacco leaves of the aerosol substrate 30. By simply taking out the tobacco holder 10 directly, the separation of the aerosol substrate 30 and the smoking device main body 20 with the heating element 22 can be realized, and the tobacco holder 10 having only the heat conduction cover 16 is still easy to clean.

[0029] Naturally, according to the design requirements, the cigarette holder 10 may be provided with a heating element 22. The heating element 22 is fixedly installed in the cigarette clamping housing 12. Referring to FIGS. 5 and 6, FIG. 5 illustrates a schematic cross-sectional structure of another exemplary embodiment of the cigarette holder of the low-temperature smoking device, and a schematic exploded view of a partial structure of another exemplary embodiment of the low-temperature smoking device. FIG. 6 illustrates a schematic structure diagram after combining the partial structures of the low-temperature smoking device in FIG. 5. As shown in FIGS. 5 and 6, since the heating element 22 is fixedly installed in the cigarette clamping housing 12, the heating element 22 and the heat conduction cover 16 are configured as an integral structure. Although this structure does not have the cost advantage of the cigarette holder structure shown in FIGS. 3 and 4, as described above, the heating structure combined with the heat conduction cover itself can simplify the requirements for the structure of the heating element itself. For example, in the embodiments shown in FIGS. 5 and 6, the heating element 22 is a heating pin that can extend along the axial direction of the cigarette clamping hole 122. Such a structure solves the problem of the high manufacturing cost of the conventional heating element and has a cost advantage compared with the conventional heating structure.

[0030] In the embodiments shown in FIGS. 5 and 6, the cigarette holder 10 further includes a conductive member 18. The conductive member 18 can be electrically connected to the heating element 22. After the cigarette holder 10 is assembled to the smoking device body 20, it can be electrically connected to the smoking device body 20 through the conductive member 18. This configuration can make the electrical connection between the cigarette holder 10 and the smoking device body 20 shown in FIGS. 5 and 6 more stable and reliable.

[0031] In the embodiments shown in FIGS. 3 and 5, the cigarette clamping housing 12 is provided with a heat insulation section 123 along the depth direction of the cigarette clamping hole 122, and the heat conduction cover 16 is located within the heat insulation section 123 along the depth direction. The heat insulation section 123 is helpful for the user's experience and prevents the poor experience caused by local overheating of the heat conduction cover.

[0032] In the embodiments shown in FIGS. 3 and 5, the tobacco clamping housing 12 further includes a mounting cap section 121 along the depth direction. The tobacco clamping hole 122 is opened in the mounting cap section 121, and a step portion 124 is provided between the mounting cap section 121 and the heat insulation section 123. The radial dimension of the step portion 124 is larger than the radial dimension of the heat insulation segment 123, so that the heat insulation section 123 can be inserted into the insertion hole opening 222 of the smoking device body 20, and the step portion 124 can be locked to the insertion hole opening 222 of the smoking device body 20. At the same time, reference may be made to FIG. 4 corresponding to FIG. 3 and FIG. 6 corresponding to FIG. 5. By adopting such an insertion structure, a gap can be formed between the heat insulation section 123 and the hole wall of the insertion hole opening 222 of the smoking device body 20, and the purpose of heat insulation can be further achieved.

[0033] The present invention further provides a low-temperature smoking device. Referring to FIG. 1, the low-temperature smoking device includes a smoking device body 20 and the above-mentioned tobacco holder 10. The smoking device body 20 includes an assembly end 21, and the tobacco clamping housing 12 is removably assembled to the assembly end 21 of the smoking device body 20. Referring to FIG. 2, the aerosol substrate 30 can be inserted into the closed end 164 of the heat conduction cover 16. At the same time, reference may be made to FIGS. 3 and 4, or FIGS. 5 and 6.

[0034] The present invention further provides a low-temperature smoking device assembly, which includes a smoking device body 20 and a set of the above-mentioned tobacco holders 10. The smoking device body 20 includes an assembly end 21, and the tobacco clamping housing 12 of each tobacco holder 10 is removably assembled to the assembly end 21 of the smoking device body 20. The depths and / or hole diameters of the tobacco clamping holes 122 of each tobacco clamping housing 12 are different from each other, and the aerosol substrate 30 can be inserted into the closed end 164 of each heat conduction cover 16.

[0035] The above are only examples of the present invention and are not intended to limit the present invention. For those skilled in the art, the present invention can be variously modified and changed. Any modifications, equivalent substitutions, improvements, etc. made without departing from the spirit and principle of the present invention should be included in the scope of the claims of the present invention.
