[0025] Reference Figures 1-5 The present application proposes an embodiment of the cigarette drying apparatus, which includes:

[0026] The device includes a body 10, which has an insertion cavity 20 and a mouthpiece 40. The insertion cavity 20 is shaped to match the cigarette. One end of the insertion cavity 20 has an opening 21 that penetrates the body 10. The other end of the insertion cavity 20 has a smoke outlet 22 that communicates with the mouthpiece 40. The insertion cavity 20 includes a heating section 23 and a non-heating section 24 distributed on the side of the heating section 23 away from the opening 21.

[0027] In this embodiment, taking the insertion cavity 20 as vertically distributed, the opening 21 as located at the lower end of the insertion cavity 20, and the mouthpiece 40 as installed on the upper end of the body 10 as an example, the end of the cigarette away from the filter is vertically inserted into the insertion cavity 20. When the cigarette is inhaled through the mouthpiece 40, the heating section 23 of the insertion cavity 20 heats the cigarette, and the smoke generated by the cigarette flows out through the mouthpiece 40.

[0028] In this application, since the non-heated section 23 of the cigarette is not heated, when the smoke generated by combustion flows upward, the tar and other organic pollutants, as well as particulate matter and dust carried in the smoke will be adsorbed and absorbed by the tobacco in the non-heated section 23, reducing the amount of harmful substances entering the human body. Furthermore, when each cigarette is heated but not burned, the end of the cigarette away from the filter tip adsorbs the tar and other organic pollutants, as well as particulate matter and dust generated by that cigarette, without reuse, thus ensuring the adsorption effect.

[0029] Furthermore, in order to further adsorb organic pollutants such as tar and particles and dust generated by cigarettes, a filter chamber 30 is provided on the main body 10. The filter chamber 30 is connected to the mouthpiece 40 and the smoke outlet 22 respectively, and a filter element 31 is provided in the filter chamber 30.

[0030] The filter element 31 includes filter cotton 311 and / or activated carbon 312. In this embodiment, the filter chamber 30 is disposed above the insertion cavity 20, and the filter element 31 includes filter cotton 311 and activated carbon 312.

[0031] Based on the above, in order to reduce wind resistance, the filter cotton 311 is provided with multiple through holes 313. Therefore, the multiple through holes 313 are arranged to be staggered with the smoke outlet 22. In this embodiment, the multiple through holes 313 are evenly distributed along the circumferential interval of the smoke outlet 22. When smoke flows from the smoke outlet 22 to the side of the filter cotton 311 near the smoke outlet 22, the smoke will be dispersed by the action of the lower end face of the filter cotton 311 and pass through the through holes 313, increasing the contact area between the smoke and the filter cotton 311 and improving the adsorption effect.

[0032] Furthermore, the main body 10 of this application is provided with a flow-guiding absorbent cotton 50, and the flow-guiding absorbent cotton 50 is provided with a flow-guiding channel 51. The two ends of the flow-guiding channel 51 are respectively connected to the smoke outlet 22 and the mouthpiece 40. The flow-guiding channel 51 is a non-linear channel, which increases the contact area between the flow-guiding absorbent cotton 50 and the smoke. Specifically, the flow-guiding channel 51 only needs to be non-linear; the flow-guiding channel 51 can be partially linear.

[0033] In this embodiment, the flow-guiding absorbent cotton 50 is disposed between the outlet of the filter chamber 30 and the mouthpiece 40. Both ends of the flow-guiding channel 51 are connected to the outlet and the mouthpiece 40 respectively, thereby allowing one end of the flow-guiding channel 51 to indirectly connect to the smoke outlet 22 through the outlet. In this embodiment, the flow-guiding channel 51 is arranged in a serpentine bend.

[0034] Preferably, the body 10 also includes an atomizing core 60, a circuit board 70, and an airflow switch 80 for detecting airflow. The atomizing core 60 has an atomizing channel 61 that communicates with the mouthpiece 40. The body 10 is equipped with a heater for heating the heating section 23. The circuit board 70 is electrically connected to the airflow switch 80 and the heater. In this embodiment, the airflow switch 80 is disposed on the atomizing core 60 and is used to detect changes in airflow within the atomizing channel 61.

[0035] When the mouthpiece 40 is inhaled, the airflow switch 80 in the atomization channel 61 detects a change in airflow and sends a signal to the circuit board 70, activating the atomizing core 60 and the heater. The atomizing core 60 can use e-liquids of different flavors, and when the user inhales, the smoke generated by the atomizing core 60 enhances the flavor of the smoke produced by the cigarette. A heating wire is installed in the atomization channel and is electrically connected to the circuit board 70.

[0036] Based on the above, the main body 10 is further provided with a detector 90. The main body 10 has a cavity 25 communicating with the opening 21. The detector 90 is installed in the cavity 25 and is used to detect cigarettes inserted into the insertion cavity 20. In this embodiment, the cavity 25 is located at the lower end of the opening 21 and is used to penetrate the main body 10. The detector 90 is a through-beam infrared sensor, which is located on opposite sides of the cavity and is used to detect the filter tip portion of the cigarette.

[0037] When the detector 90 does not detect cigarettes, even if the user inhales through the mouthpiece 40, the airflow switch 80 detects a change in airflow, and the atomizing core 60 and heater do not work; when the detector 90 detects cigarettes, it sends a signal to the detector 90. When the user inhales through the mouthpiece 40, the airflow switch 80 detects a change in airflow, and the atomizing core 60 and heater start working to produce smoke.

[0038] The heating section 23 is composed of a heating tube 100 installed on the body 10. The inner cavity of the heating tube 100 forms the insertion cavity 20. The heating tube 100 includes a plurality of connecting parts 101 arranged sequentially from top to bottom. A heating part 102 is installed between each pair of adjacent connecting parts 101. That is, the heater is the heating tube.

[0039] Based on the above, the connection part 101 closest to the opening 21 is electrically connected to the first pin, and each connection part 101 located between two adjacent heating parts 102 is electrically connected to the second pin. The first pin and the second pin are used to connect to electrodes with opposite polarities, respectively.

[0040] In this embodiment, the heating tube 100 includes four heating sections 102, each of which is a resistance heating wire. The four heating sections 102 can heat the cigarette separately without burning it, simulating a real smoking situation. Moreover, the heating section 102 uses resistance heating, which is directly detached from the cigarette. Compared with the thick film heating technology of the prior art, the heating efficiency is higher and the manufacturing cost is lower.

[0041] Specifically, the connection portion 101 closest to the opening 21 is electrically connected to the first pin, and each connection portion 101 located between two adjacent heating portions 102 is electrically connected to the second pin. The first pin and the second pin are used to connect to electrodes with opposite polarities, so that the multiple heating portions 102 are connected in parallel to achieve segmented heating of the multiple heating portions 102.

[0042] Alternatively, the heating element 102 may be made of electromagnetic heating material. By setting electromagnetic coils corresponding to multiple heating elements 102 one by one outside the heating tube 100, the electromagnetic coils are energized one by one to make the multiple heating elements 102 heat up one by one and heat the cigarette.

[0043] Of course, this utility model is not limited to the above-described embodiments. Those skilled in the art can make equivalent modifications or substitutions without departing from the spirit of this utility model. All such equivalent modifications and substitutions are included within the scope defined by the claims of this application.
