[0018] This embodiment uses a hollow heating needle 3, which allows fresh air to enter the interior of the heated non-combustible cigarette, improving the smoke output and helping to cool the smoke.

[0019] The cleaning component is used to clean the hollow heating needle 3, ensuring smooth airflow and maintaining the heating efficiency of the hollow heating needle 3. The elastic element is used to reset the cleaning component.

[0020] Specifically, the hollow heating needle 3 has a cylindrical structure, and a conical end 4 is formed at the top of the hollow heating needle 3. Multiple vent holes 5 extending axially are opened inside the hollow heating needle 3, and all the vent holes 5 are distributed at equal intervals in the circumferential direction around the axis of the hollow heating needle 3.

[0021] In this embodiment, there are four vent holes 5. The four vent holes 5 are evenly distributed around the axis of the hollow heating needle 3 in the circumferential direction. The upper opening of the vent hole 5 is located on the conical surface of the conical end 4, and the lower opening of the vent hole 5 is located on the bottom surface of the hollow heating needle 3.

[0022] To ensure that air can smoothly enter the vent 5 from the bottom of the hollow heating needle 3, a connecting post 6 is provided at the bottom end of the hollow heating needle 3. The diameter of the connecting post 6 is smaller than the outer diameter of the hollow heating needle 3.

[0023] By setting the connecting column 6, a certain gap is made between the bottom surface of the hollow heating needle 3 and the partition plate 2 to ensure air circulation.

[0024] Furthermore, the top of the partition 2 is provided with a heating needle mounting seat 7, the lower end of the connecting column 6 is fixedly connected to the heating needle mounting seat 7, the elastic element is a return spring 8, the number of return springs 8 is at least two, the return springs 8 are evenly distributed around the hollow heating needle 3, the lower end of the return spring 8 is fixedly connected to the heating needle mounting seat 7, and the upper end of the return spring 8 is fixedly connected to the cleaning component.
