the heat-insulating reflecting devices are discontinuously distributed, so that concentrated heat collection of a plurality of areas is formed.

The thermal radiation continuously generated by the photo-thermal generating device when the photo-thermal generating device is electrified is subjected to radial divergent reflection through the heat preservation reflecting device, and the problem of diffusion cannot exist due to the fact that the reflection is radial divergent, so that the heat preservation effect is better compared with the traditional device without the reflection function.

Specifically, the photothermal generation device is a heating tube 1, and the heating tube 1 generates photothermal and radiates to be diffused after being electrified, and the power source is supplied by low-voltage power, so that the power consumption is low.

The technical effect brought by the low power consumption is that the thermal and optical radiation is relatively small, causing less damage to the human body, especially to the hair, and thus being more user-friendly.

In the embodiment of the invention, the power consumption can be ensured to be low by supplying power with lower voltage.

The heat preservation reflecting piece 2 can continuously reflect and gather heat radiation generated by electrifying the heating tube 1 without diffusing to the outside.

Correspondingly, the setting of refraction portion 3 can extend the heat to the export direction, does benefit to the fluid of output and carries out long distance's heating, or directly utilizes the heat after the refraction to dry the hair, has the guide effect.

As another preferred embodiment of the present invention, the heat insulation device 4 is provided with a mounting hole for fixing the photothermal generation device, and the photothermal generation device penetrates through the mounting hole, and it is obvious that the specific mounting position of the photothermal generation device in the present application is not limited;

for example, the photothermal generation device may be mounted on the heat insulating reflector 2.

As shown in fig. 3, as a preferred embodiment of the present invention, a gap for fluid to enter is disposed between two adjacent heat-insulating reflectors 2, a connecting member for fixing the two heat-insulating reflectors 2 is disposed at the gap, the gap can provide a passage for the fluid to enter, and the fluid is poured into the photo-thermal structure through the gap to be heated and then blown out, so as to achieve flowing heat exchange of the fluid.

It should be noted that the heat-insulating reflecting member 2 may also be an integral body, and the gap may be annularly disposed on the inner wall of the heat-insulating reflecting member 2 along the axial direction of the cup body.

As a preferred embodiment of the present invention, the photothermal generation device penetrates through the heat insulation device to be connected with a cable, and the cable is used for connecting the photothermal generation device with a power supply device.

Note that, when the heating tube 1 is connected to the heat insulation device 4, a sealing flame retardant treatment needs to be performed at the connection, specifically, a flame retardant rubber ring is sleeved on one side, and since the heat attached to the heating tube 1 is large, the flame retardant treatment can be performed at the connection in order to avoid hot melting other components.
