Description

The present invention belongs to the field of smoking devices, and more specifically, to a cigarette holder for a low-temperature smoker, and a low-temperature smoker and a low-temperature smoker assembly including said cigarette holder.

Related research has shown that the combustion temperature of a conventional cigarette is over 800°C, and that over 5,000 chemical substances are produced during the burning process of a cigarette, of which over 80 are carcinogenic, and that the smoke produced thereby poses great harm to non-smokers. Non-combustion heating technology is a technology in which an aerosol substrate (also called non-combustion heating tobacco) is directly heated by a low-temperature smoking device, but does not burn to produce smoke. The harmful substances produced by this heating method are significantly reduced compared to those produced by burning conventional cigarettes, meeting consumer needs while reducing harm to the body.

The primary application of non-combustion heating technology is the low-temperature smoker, which heats the aerosol substrate to initiate a pyrolysis reaction that heats the tobacco material within the aerosol substrate just enough to produce tobacco flavor and smoke as the user inhales.

Conventional low-temperature smoking devices have a tobacco clamping hole for clamping the aerosol substrate, and a heating body installed in the tobacco clamping hole is inserted into the aerosol substrate to heat the aerosol substrate. Currently, there are various different types of aerosol substrates on the market, and the aerosol substrates have different lengths and diameters, which requires tobacco clamping holes with different hole diameters and depths to match the aerosol substrates. The hole diameter and depth of the tobacco clamping hole of conventional low-temperature smoking devices are difficult to change, and generally can only be matched with one type of aerosol substrate, which limits the use effect, makes it difficult to meet the use needs of users, and is not highly compatible.

In addition, to fit different model aerosol substrates, a correspondingly different heater structure is required. Conventional low-temperature smokers generally use a ceramic sheet as a heater to heat the aerosol substrate. The ceramic sheet is expensive and its structure is easily damaged, and users generally need to be careful each time they insert or remove the aerosol substrate. Therefore, the conventional heater structure makes conventional low-temperature smokers unsuitable for modification into compatible products.

One object of the present invention is to provide a cigarette holder for a low temperature smoking device, which provides improved compatibility between the heating element and the aerosol substrate.
Another object of the present invention is to provide a low-temperature smoking device equipped with the above-mentioned cigarette holder.
It is a further object of the present invention to provide a low temperature smoking assembly comprising a pair of the above-mentioned cigarette holders.

The present invention provides a cigarette holder for a low-temperature smoking tool, the low-temperature smoking tool comprising a smoking tool body and a heating body, the cigarette holder comprising a tobacco clip housing and a heat-conducting cover, the tobacco clip housing being removably assembled to the smoking tool body, the tobacco clip housing being formed with a tobacco clip hole for positioning the aerosol substrate, the heat-conducting cover being provided on the tobacco clip housing, the heating body being inserted into the open end of the heat-conducting cover, the aerosol substrate being inserted into the closed end of the heat-conducting cover, so that the heating body can heat the aerosol substrate through the heat-conducting cover. The cigarette holder is assembled to the smoking tool body, the aerosol substrate that generates smoke is provided in the tobacco clip hole, the connection between the aerosol substrate and the smoking tool body is realized by the cigarette holder, and the heating body can be inserted into the heat-conducting cover to heat the aerosol substrate, thereby changing the mode of heat conduction between the heating body and the aerosol substrate, preventing mutual influence between the heating body and the aerosol substrate, and improving compatibility between the heating body and the aerosol substrate.

In one exemplary embodiment of a cigarette holder for a low-temperature smoker, the smoking device body is provided with a heating element, and the heating element can be inserted into the heat-conducting cover through the open end after the cigarette holder is assembled to the smoking device body.

In an exemplary embodiment of the cigarette holder of the low-temperature smoking device, the cigarette holder includes a heating element fixed to the cigarette clip housing. The heating element is provided in the cigarette holder, and the dimensions of the heating element match those of the thermally conductive cover, so that the heat generated by the heating element can be rapidly transferred to the thermally conductive cover, improving comfort during inhalation.

In one exemplary embodiment of a cigarette holder for a low-temperature smoking device, the cigarette holder further includes a conductive member, which can be electrically connected to the heating element, and the cigarette holder can be electrically connected to the smoking device body via the conductive member after being assembled to the smoking device body.

In an exemplary embodiment of the cigarette holder of the low-temperature smoking device, the heating body 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-conducting cover, and the extension direction of the heating pin is the axial direction of the tobacco clamping hole. When the aerosol substrate passes through the tobacco clamping hole and is positioned, the aerosol substrate is also positioned in the tobacco clamping hole by following the axial direction of the heating hole, and the heating pin can uniformly heat the aerosol substrate.

In one exemplary embodiment of the low temperature smoking device cigarette holder, the heat conducting cover is a cone-shaped cover. The cone-shaped cover facilitates the insertion of the heating element and allows the aerosol substrate to be inserted quickly.

In an exemplary embodiment of the cigarette holder of the low-temperature smoking device, the tobacco clip housing has an insulating section along the depth direction of the tobacco clip hole, and the heat-conducting cover is located within the insulating section along the depth direction. The insulating section can prevent the heating body from transferring heat to the smoking device body when heated, thereby preventing the user from being burned.

In one exemplary embodiment of a cigarette holder for a low-temperature smoking device, the tobacco clip housing further includes an attachment cap section along the depth direction, the tobacco clip hole is opened in the attachment cap section, a step portion is provided between the attachment cap section and the insulating section, the insulating section can be inserted into the insertion hole of the smoking device body, and the step portion can be engaged with the insertion hole opening of the smoking device body. The tobacco clip housing can be tightly connected to the smoking device body by being connected to the smoking device body by fitting between the attachment cap section, the step portion, and the insulating section.

The present invention further provides a low-temperature smoking device comprising a smoking device body and the above-mentioned cigarette holder, the smoking device body having an assembly end, the tobacco clip housing being removably assembled to the assembly end of the smoking device body, and an aerosol substrate being insertable into the closed end of the heat-conducting cover.

The present invention further provides a low-temperature smoking device assembly comprising a smoking device body and a set of the above-mentioned cigarette holders, the smoking device body having an assembly end, the tobacco clip housing of each cigarette holder being removably assembled to the assembly end of the smoking device body, the depth and/or hole diameter of the tobacco clip hole of each tobacco clip housing being different, and an aerosol substrate can be inserted into the closed end of each heat-conducting cover. Since the depth and/or hole diameter of the tobacco clip hole of each tobacco clip housing are different, different types of cigarette holders can meet the dimensions of most aerosol substrates, and each cigarette holder can be assembled with the smoking device body, thus connecting the smoking device body and the aerosol substrate by the tobacco holder improves the compatibility of the smoking device body, making it possible to meet the needs of one smoking device body and reducing costs.

Figure 1 is a structural schematic diagram of an exemplary embodiment of a cigarette holder of a low-temperature smoking device, and an exploded structural schematic diagram of an exemplary embodiment of a low-temperature smoking device. Figure 2 is a structural schematic diagram of the low-temperature smoking device in Figure 1 after it is assembled. As shown in Figure 1, the low-temperature smoking device comprises a smoking device main body 20 and a cigarette holder 10. Here, as shown by the solid line in the figure, the cigarette holder 10 comprises a tobacco clip housing 12, and the tobacco clip housing 12 is removably assembled to the smoking device main body 20 along the dotted connection line in the figure, and the assembled structure may also be referred to in Figure 2. In addition, a tobacco clip hole 122 that can position the aerosol substrate 30 is formed in the tobacco clip housing 12, and the aerosol substrate 30 can be inserted into the tobacco clip hole 122, and the inserted state may also be referred to in Figure 2.

3 is a schematic cross-sectional view of an exemplary embodiment of a cigarette holder of a low-temperature smoking device, and an exploded schematic view of a local structure of an exemplary embodiment of a low-temperature smoking device. FIG. 4 illustrates a schematic structure of the low-temperature smoking device after combining the local structures in FIG. 3. As shown in FIG. 3 and FIG. 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 body. As shown in the solid line part of FIG. 3, the cigarette holder 10 further includes a heat-conducting cover 16, which is provided on the cigarette clip housing 12, and which has an open end 162 and a closed end 164 opposite the open end 162. The heating element 22 can be inserted into the open end 162 of the heat-conducting cover 16, and the aerosol substrate 30 can be inserted into the closed end 164 of the heat-conducting cover 16, so that the heating element 22 can heat the aerosol substrate 30 through the heat-conducting cover 16.

Different cigarette holders 10 can have different depths and hole sizes, so that different cigarette holders 10 can be adapted to different types of aerosol substrates. At the same time, to accommodate different depths and hole sizes, i.e., to accommodate different types of aerosol substrates, the cigarette holders 10 are correspondingly fitted with heat-conducting covers of different sizes or models. A user can arrange multiple cigarette holders as described above and select according to actual use, which improves the suitability of the low-temperature smoking device for use.

After replacing the conventional type of ceramic chip heating body structure with a heating structure combined with a heat conductive cover, the size of the heat conductive cover determines the heating area for heating the aerosol substrate, and the shape of the heat conductive cover affects the heating effect and the use effect. As can be seen, the method of combining the heat conductive cover can reduce the requirements for the structure of the heating body itself, for example, the heating body structure with a relatively high cost can be standardized and manufactured in a batch, and then the heat conductive cover with a different size or model number with a relatively low cost can be matched, and the heating effect and the use effect of the heating body can be expanded, for example, in the embodiment shown in Figures 3 and 4, the heat conductive cover 16 can adopt a conical cover, which can improve the heating angle and increase the heating area, and also reduce the friction force between the tobacco leaves in the aerosol substrate and the tobacco leaves in the aerosol substrate during the insertion and removal process of the aerosol substrate, preventing the tobacco leaves from remaining in the heat conductive cover.

In the embodiment shown in FIG. 3, the smoking device body 20 is provided with the heating element 22, the cigarette holder 10 is assembled to the smoking device body 20, and the heating element 22 can be inserted into the heat-conducting cover 16 through the open end 162. As described above, after adopting the heating structure combined with the heat-conducting cover, the cigarette holder 10 may not have the heating element 22, and the heating element 22 may be located in the smoking device body 20, so that the heating structure can be adapted to different types of aerosol substrates by changing the model number or dimensions of the heat-conducting cover. In this manner, the structure of the cigarette holder 10 can be further simplified, the manufacturing cost of the cigarette holder can be greatly reduced, and the cigarette holder 10 can be adapted to meet the compatibility by simply matching different heat-conducting covers. In this way, when a user has a smoking device body with a heating element, he or she only needs to select a cigarette holder that matches a different model number of the heat-conducting cover as needed, and since the cost of the cigarette holder with the above structure is low, the user intends to have more models of the above cigarette holder.

In addition, since the cigarette holder 10 does not have a heating element 22, the cigarette 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 in the heating element 22. The heating element itself is generally heated by electrical conduction, which is inconvenient when cleaning, so the tobacco extractor can be used to remove the entire aerosol substrate 30. As shown in Figures 3 and 4, the heat-conducting cover 16 is provided on the heating element 22, so that the heating element 22 does not come into direct contact with the tobacco leaves of the aerosol substrate 30. The aerosol substrate 30 and the smoking article body 20 with the heating element 22 can be separated by simply removing the cigarette holder 10 directly. The cigarette holder 10 with only the heat-conducting cover 16 is still easy to clean.

Of course, according to design needs, the cigarette holder 10 may be equipped with a heating body 22, and the heating body 22 is fixed to the cigarette clip housing 12. With reference to FIG. 5 and FIG. 6, FIG. 5 illustrates a schematic cross-sectional structure of another exemplary embodiment of a cigarette holder of a low-temperature smoking device, and an exploded schematic view of the local structure of another exemplary embodiment of a low-temperature smoking device. FIG. 6 illustrates a schematic structure diagram after combining the local structure of the low-temperature smoking device in FIG. 5. As shown in FIG. 5 and FIG. 6, the heating body 22 is fixed to the cigarette clip housing 12, so that the heating body 22 and the heat conductive cover 16 are configured as an integral structure, which does not have the cost advantage of the cigarette holder structure shown in FIG. 3 and FIG. 4. However, as mentioned above, the heating structure itself combined with the heat conductive cover can simplify the requirements for the structure of the heating body itself. For example, in the embodiment shown in FIG. 5 and FIG. 6, the heating body 22 is a heating pin that can be extended along the axial direction of the cigarette clip hole 122. Such a structure solves the problem of high manufacturing costs of the conventional heating body, and has a cost advantage over the conventional heating structure.

In the embodiment shown in Figures 5 and 6, the cigarette holder 10 further includes a conductive member 18, which can be electrically connected to the heating element 22, and after the cigarette holder 10 is assembled to the smoking device body 20, it can be electrically connected to the smoking device body 20 via the conductive member 18. This configuration can make the electrical connection between the cigarette holder 10 and the smoking device body 20 shown in Figures 5 and 6 more stable and reliable.

3 and 5, the cigarette clip housing 12 has an insulating section 123 along the depth of the cigarette clip hole 122, and the heat conductive cover 16 is located within the insulating section 123 along the depth. The insulating section 123 is beneficial to the user's experience and prevents a poor experience caused by local overheating at the heat conductive cover.

3 and 5, the cigarette clip housing 12 further includes a mounting cap section 121 along the depth direction, the cigarette clip hole 122 is opened in the mounting cap section 121, and a step 124 is provided between the mounting cap section 121 and the insulating section 123, and the radial dimension of the step 124 is larger than the radial dimension of the insulating segment 123, so that the insulating section 123 can be inserted into the insertion hole opening 222 of the smoking article body 20, and the step 124 can be engaged with the insertion hole opening 222 of the smoking article body 20. At the same time, refer 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 insulating section 123 and the hole wall of the insertion hole opening 222 of the smoking article body 20, and the purpose of insulation can be further achieved.

The present invention further provides a low-temperature smoking device, and referring to FIG. 1, the low-temperature smoking device comprises a smoking device body 20 and the above-mentioned cigarette holder 10, the smoking device body 20 comprises an assembly end 21, and the tobacco clip housing 12 is removably assembled to the assembly end 21 of the smoking device body 20; referring to FIG. 2, an aerosol substrate 30 can be inserted into the closed end 164 of the heat-conducting cover 16; and referring to FIG. 3 and FIG. 4, or FIG. 5 and FIG. 6.

The present invention further provides a low-temperature smoking device assembly, which comprises a smoking device body 20 and a pair of the above-mentioned cigarette holders 10. The smoking device body 20 has an assembly end 21, the tobacco clip housing 12 of each cigarette holder 10 is removably assembled to the assembly end 21 of the smoking device body 20, the tobacco clip hole 122 of each tobacco clip housing 12 has a different depth and/or hole diameter, and an aerosol substrate 30 can be inserted into the closed end 164 of each heat-conducting cover 16.

The above is merely an embodiment of the present invention, and is not intended to limit the present invention. Those skilled in the art will appreciate that the present invention is susceptible to various modifications and variations. Any modifications, equivalent replacements, improvements, etc. made without departing from the spirit and principles of the present invention should be included within the scope of the claims of the present invention.
