[0029] The present application will be described in detail below in combination with the drawings and specific embodiments. It should be noted that in the drawings or description, similar or identical parts are denoted by the same reference numerals, and the implementation modes not shown or described in the drawings are known to those skilled in the art. In addition, the directions mentioned in the embodiments, such as "up", "down", "top", "bottom", "left", "right", "front", "back", etc., are only the directions of the drawings, and are not intended to limit the protection scope of the present application.

[0030] As Figs. 1-2As shown, the novel heating cigarette filter rod comprises a filter rod section 20 connected with a tobacco section 10. The filter rod section 20 comprises a lip section 21, an intermediate section 22 and a tobacco section 23 connected in sequence. The tobacco section 23 is connected with the tobacco section 10. The lip section 21 and the tobacco section 23 are both provided with filter material for filtering large particles and harmful components in smoke. The intermediate section 22 is used for cooling smoke. Specifically, the intermediate section 22 is provided with a channel, and a mounting rod 30 is coaxially arranged in the channel. The mounting rod 30 is provided with a first spiral vane 31 on the circumferential side. The circumferential side of the first spiral vane 31 abuts to the inner wall of the intermediate section 22. The first spiral vane 31 and the inner wall of the intermediate section 22 enclose an airflow channel. In the application, the spiral airflow channel is arranged to prolong the flow time and flow distance of airflow in the filter, so as to increase the cooling time, thereby improving the cooling effect and improving the smoking taste of the heating cigarette.

[0031] In the application, the first spiral vane 31 is provided with a turbulence component. The turbulence component is used to improve the heat exchange between smoke and air in the cavity, and has a shearing effect on smoke aerosol particles, which is beneficial to improve the smoke yield. The turbulence component is arranged to disturb the airflow, thereby further improving the sensory quality of smoking by reducing the temperature of smoke and improving the smoke yield.

[0032] Specifically, the turbulence component comprises a second spiral vane 33. The first spiral vane 31 and the second spiral vane 33 are both provided with turbulence holes 32. The second spiral vane 33 is slidably arranged at the position corresponding to the first spiral vane 31 on the circumferential side of the mounting rod 30. The second spiral vane 33 can be slid to communicate or not communicate with the two turbulence holes 32. In this way, the opening degree of the turbulence hole 32 or the opening and closing of the turbulence hole 32 are controlled by rotating the second spiral vane 33. The mounting rod 30 is provided with a spiral sliding groove 34 matched with the sliding of the second spiral vane 33. The second spiral vane 33 always abuts to the first spiral vane 31 during the sliding along the spiral sliding groove 34.

[0033] As Fig. 2 , the turbulence hole 32 is provided with multiple groups. Preferably, the connecting lines between adjacent turbulence holes 32 on the first spiral vane 31 are not parallel to the axial direction of the mounting rod 30. In this way, the airflow is prevented from directly flowing out of the airflow channel in a straight line along the turbulence hole 32.

[0034] One end of the second spiral vane 33 is provided with a driving disc 36. The driving disc 36 is used to drive the second spiral vane 33 to slide along the spiral sliding groove 34. In order to prevent the driving disc 36 from interfering with the airflow, the application is provided with a relief hole 37 on the driving disc 36.

[0035] Supporting columns 35 are arranged at both ends of the mounting rod 30 near the end positions. The supporting columns 35 can help the mounting rod 30 to be embedded in the middle section 22, and can cooperate with the mounting rod 30 and the first spiral fan blade 31 to support the middle section 22, preventing the middle section from being bent and deformed.

[0036] The novel heating cigarette filter rod is described in detail above. The description of the specific embodiments is only used to help understand the method of the present application and its core idea. It should be pointed out that, for those skilled in the art, without departing from the principles of the present application, the present application can be improved and modified in many ways, and these improvements and modifications also fall within the protection scope of the present application.
