[0037] The heated non-combustion appliance of the embodiments of the present application is described in detail as follows Figures 1 to 5 The sensor 3 is a photoelectric sensor, and the sensor 3 is installed on the appliance body 1 and can be electrically connected with the circuit board 12. The light-transmitting member 2 has a light transmission path in the plane perpendicular to the extension direction of the accommodating cavity 17, which communicates the inside and outside of the accommodating cavity 17, and the optical signal can be transmitted through the light-transmitting member 2 from the inside of the accommodating cavity 17 to the outside of the accommodating cavity 17 and from the outside of the accommodating cavity 17 to the inside of the accommodating cavity 17 in the extension direction of the light transmission path. The sensor 3 is located outside the accommodating cavity 17, and the sensor 3 has a detection end facing the light-transmitting member 2 in the extension direction of the light transmission path, and the sensor 3 can transmit the optical signal to the inside of the accommodating cavity 17 through the detection end to detect whether the aerosol product 6 is accommodated in the accommodating cavity 17.

[0038] In an embodiment, the sensor 3 is a photoelectric sensor, and the sensor 3 is installed on the appliance body 1 and can be electrically connected with the circuit board 12. The light-transmitting member 2 has a light transmission path in the plane perpendicular to the extension direction of the accommodating cavity 17, which communicates the inside and outside of the accommodating cavity 17, and the optical signal can be transmitted through the light-transmitting member 2 from the inside of the accommodating cavity 17 to the outside of the accommodating cavity 17 and from the outside of the accommodating cavity 17 to the inside of the accommodating cavity 17 in the extension direction of the light transmission path. The sensor 3 is located outside the accommodating cavity 17, and the sensor 3 has a detection end facing the light-transmitting member 2 in the extension direction of the light transmission path, and the sensor 3 can transmit the optical signal to the inside of the accommodating cavity 17 through the detection end to detect whether the aerosol product 6 is accommodated in the accommodating cavity 17.

[0039] Since the light transmission piece 2 separates the space inside and outside the accommodating cavity 17, and the light transmission piece 2 has a light transmission path communicating the inside and outside of the accommodating cavity 17, the light signal emitted by the sensor 3 located outside the accommodating cavity 17 can pass through the light transmission piece 2 into the accommodating cavity 17 along the light transmission path, so as to facilitate the detection of whether the aerosol product 6 is accommodated in the accommodating cavity 17, and the sensor 3 and the heating piece 13 are electrically connected with the circuit board 12, when the sensor 3 detects that the aerosol product 6 is accommodated in the accommodating cavity 17, the heating piece 13 can be controlled to heat by the circuit board 12, so as to realize the self-starting of the heating non-combustion appliance, when the sensor 3 does not detect that the aerosol product 6 is accommodated in the accommodating cavity 17, the heating piece 13 is kept in a non-heating state controlled by the circuit board 12, so that the heating non-combustion appliance of the present application actually provides a hardware platform for realizing the self-starting function, and facilitates the self-starting of the heating non-combustion appliance.

[0040] In addition, since the light transmission piece 2 separates the space inside and outside the accommodating cavity 17, and the sensor 3 is located outside the accommodating cavity 17, the aerosol or condensate generated in the accommodating cavity 17 can be prevented from entering the sensor 3 and affecting the normal work of the sensor 3, which helps to ensure the stability and reliability of the work of the sensor 3, and also can improve the service life of the sensor 3.

[0042] Of course, in another embodiment, the detection end of the sensor 3 can be arranged to abut the light-transmitting member 2 in the light-transmission path extension direction, and the light signal emitted by the detection end of the sensor 3 can directly pass through the light-transmitting member 2 into the accommodating cavity 17, without the need to arrange the light-transmission member 4, thereby reducing the loss of the light signal during transmission, and improving the light signal transmission efficiency of the sensor 3.
