[0078] Additionally, the control unit (150) can stop the operation of the thermoelectric heat exchanger (191) and the refrigerant pump (193) if the measured value of the temperature sensor (136) is less than a preset value.

[0079] The above supply device (100) may further include a display (114) installed on the outer surface of the housing (110) and a speaker (115) installed on the outer surface of the housing (110).

[0082] The control unit (150) may have sound information pre-set to explain the state of the supply device (100), and may output the pre-set sound information through the speaker (115) to make the passenger aware of it.

[0084] As described above, a supply device according to one embodiment of the present invention can supply clean air contained in an air can to the interior of a vehicle by discharging it through an air injection unit.

[0085] In addition, the vehicle clean air supply device can be stably inserted into and fixed in the vehicle's cup holder through the housing fixing part.
