[0030] The heating non-combustion device provided by the embodiments of the present application can detect whether the aerosol product is inserted into the accommodation channel 13 through the detection member 2, and the control module 15 can control the heating assembly 14 to heat or stop heating according to the detection result of the detection member 2, without using a gas pressure sensor. This can avoid the backflow of condensate affecting the control of the control module 15 on the heating assembly 14, help to ensure the normal operation of the heating non-combustion device, and improve the working stability of the heating non-combustion device.

[0031] Please refer to Figures 1 to 4 The heating non-combustion device provided by the embodiments of the present application includes a device main body 1, a detection member 2, and a light-transmitting member 3. The device main body 1 has an accommodation channel 13 extending in a first direction, and the accommodation channel 13 is open at one end in the extending direction. An aerosol product (not shown in the figure) can be inserted into the accommodation channel 13 from the opening. The device main body 1 further includes a heating assembly 14, a control module 15, and a light-transmitting member 16. The heating assembly 14 can include a heating cylinder that encloses the channel wall of the accommodation channel 13, or the heating assembly 14 can further include a heating needle that penetrates into the aerosol product. In this way, the heating assembly 14 can heat the aerosol product by directly contacting the aerosol product. Alternatively, the heating assembly 14 includes a heating cylinder that does not directly contact the aerosol product. The heating cylinder heats the air flow to form a hot air flow, and the hot air flow enters the accommodation channel 13 to heat the aerosol product. The heating assembly 14 can be electrically connected to the control module 15, and the heating assembly 14 can be controlled to heat or stop heating by the control module 15. The control module 15 includes a circuit board and electronic components mounted on the circuit board.

This can prevent the aerosol from adhering to the detection member 2 and reducing the sensitivity of the detection member 2, and help to ensure the normal operation of the heating non-combustion device.

[0033] The light-transmitting piece 16 is coplanar with the inner wall surface of the channel wall of the accommodation channel 13 in the second direction towards the inner side of the accommodation channel 13, so that the aerosol product can be smoothly and unobstructedly inserted into the accommodation channel 13 from the opening.

Since the detection piece 2 and the heating assembly 14 are electrically connected with the control module 15, the control module 15 can control the heating assembly 14 to heat according to the detection result of the detection piece 2, for example, when there is an aerosol product in the accommodation channel 13, the control module 15 can control the heating assembly 14 to heat, and when there is no aerosol product in the accommodation channel 13, the control module 15 can control the heating assembly 14 to stop heating.

[0036] In some embodiments, please continue to refer to Figure 2 and Figure 3 The device body 1 has a positioning groove 123, the groove opening of the positioning groove 123 is towards the light-transmitting piece 16 in the second direction, the positioning groove 123 also has a socket towards the first direction, and the detection piece 2 can be inserted into the positioning groove 123 from the socket; in an embodiment, the detection piece 2 can be fixed on the groove bottom wall of the positioning groove 123 by adhesive; in another embodiment, the detection piece 2 includes a plate body 21 and a detection end 22 arranged on the plate body 21, and a limiting protrusion (not shown in the figure) can also be arranged on the groove bottom wall of the positioning groove 123, a limiting hole (not shown in the figure) is arranged on the plate body 21 and matched with the limiting protrusion, the hole wall of the limiting hole and the limiting protrusion are in abutment in the first direction and the third direction, and the plate body 21 is also press-fitted and fixed between the light-transmitting piece 3 and the device body 1 in the second direction, so that the relative fixation of the detection piece 2 and the device body 1 is realized, the transmission direction of the detection light is ensured, and the detection precision and accuracy of the detection piece 2 are improved.

The light passing member 3 also abuts against the device main body 1 in the first direction. In this way, the relative fixation of the light passing member 3 and the device main body 1 can be achieved by the plug-in matching and the abutment in the first direction, without the need for additional fasteners, which facilitates the installation of the light passing member 3.
