[0042] See also Figure 6 An embodiment of the present invention further provides a cooling medication light therapy hood control circuit, which is applied to a controller on a circuit control board in a cooling medication light therapy hood.

[0043] like Figure 6 As shown, the method includes steps S110 to S140.

[0044] S110. In response to a power-on instruction, a spray start signal is generated according to the power-on instruction to control the spray component to spray a preset dose of medicine within a preset time period.

[0045] In this embodiment, in order to achieve accurate control of the drug dosage, the controller responds to the power-on instruction and generates a spraying start signal according to the power-on instruction; wherein the power-on instruction can be triggered by relevant personnel or timed triggering, which is not specifically limited here. In addition, the spraying start signal includes parameters such as spraying time, spraying dosage, and spraying speed; thereby, the spraying start signal is used to control the spraying component to spray a preset dosage of the drug within a preset time period, and once the spraying is completed, the spraying component is closed.

[0046] S120, acquiring in real time an average first temperature value of a plurality of first temperature sensors and a first temperature value of a second temperature sensor.

[0047] In this embodiment, in order to ensure that the temperature control inside the cooling drug delivery phototherapy hood achieves the best effect, the controller will monitor the temperature of the part in contact with the phototherapy hood in real time through a number of first temperature sensors, and then average the temperature monitored by each of the several first temperature sensors to obtain the first temperature average value of the several first temperature sensors; and the controller will also monitor the temperature of the part to be treated in real time through the second temperature sensor to obtain the first temperature value of the second temperature sensor, thereby realizing accurate monitoring and effective control of the temperature inside the cooling drug delivery phototherapy hood through the real-time acquired first temperature average value and first temperature value.

[0048] S130: If it is monitored that the first temperature average value is greater than a first preset temperature threshold or the second temperature value is greater than the first preset temperature threshold, a cooling air start signal is generated to control the cooling component to release cold air.

[0049] In this embodiment, after acquiring the first temperature average value of several first temperature sensors and the first temperature value of the second temperature sensor in real time, the controller compares the first temperature average value with the first preset temperature threshold or compares the second temperature value with the first preset temperature threshold to obtain a comparison result; when the monitored comparison result is that the first temperature average value is greater than the first preset temperature threshold or the second temperature value is greater than the first preset temperature threshold, it means that the temperature of the part in contact with the phototherapy hood is too high or the temperature of the part to be treated is too high. At this time, a cooling air start signal is generated to control the cooling component to release cold air, thereby achieving cooling of the cooling drug delivery phototherapy hood.

[0050] S140: If it is monitored that the first temperature average value is less than a second preset temperature threshold or the second temperature value is less than the second preset temperature threshold, a cooling air shutoff signal is generated to control the cooling component to stop releasing cold air.

[0051] In this embodiment, when the monitored comparison result is that the second temperature average value is less than the first preset temperature threshold or the second temperature value is less than the first preset temperature threshold, it means that the temperature of the part in contact with the phototherapy hood has dropped to the first preset temperature threshold or the temperature of the part to be treated has dropped to the first preset temperature threshold. At this time, a cooling air start signal is generated to control the cooling component to stop releasing cold air to improve the user experience.
