When using this product neck face function of blowing, make first air outlet 102 be located the below, wear the neck with main part 10, go up wind-shield sliding part 12 because gravity slides down along last sliding rail 103 for first air outlet 102 is sheltered from by last wind-shield sliding part 12 down, and first air outlet 102 just faces with neck face with outside intercommunication and wind gap orientation. The upper wind sliding plates 121 slide downward due to gravity, so that the adjacent upper wind sliding plates 121 are abutted, and the driving head 1221 is positioned in the sliding groove 1211. When the switch is pressed down, the control module 3 controls the centrifugal fan 5 to rotate, external air enters through the air inlet 104 and is blown out of the neck face through the first upper air outlet 102, and therefore air circulation near the neck face is accelerated, and the temperature is reduced. The main body 10 is removed to locate the first upper outlet 101 at the lower side, the main body 10 is worn on the neck, and the upper wind-blocking sliding portion 12 slides downward to block the first upper outlet 101, so that the air is blown out toward the neck face through the first lower outlet 102. Because the opening area of first air outlet 102 is different with first upper air outlet 101 for the area of blowing of neck face is different promptly the circulation of air speed is different, thereby makes the cooling effect different, through wearing or wearing main part 10 conversely, can realize the regulation of cooling effect. The switch is pressed again and the centrifugal fan 5 stops rotating.

When the face blowing function of the product is used, the first lower air outlet 102 is located below, the main body part 10 is worn on the neck, the external part 20 is held by the hand, the atomizing spray holes 205 are upward, and the lower connecting part 21 and the upper connecting part 11 are just abutted tightly. The magnetic lower connecting ring 211 and the upper connecting ring 111 are magnetically attracted to each other to be fixed relatively, and meanwhile, the electrode base 212 upwardly enters the upper connecting ring 111 and abuts against the self-resetting sealing plate 112 to enable the self-resetting sealing plate 112 to rotate and open, so that the main body portion 10 is communicated with the interior of the external portion 20. In the process, the magnetic lower connecting ring 211 magnetically attracts the iron block 1222 to slide downwards, the driving head 1221 slides downwards relative to the sliding groove 1211, and the width of the end of the driving head 1221 away from the iron block 1222 is greater than the width of the end close to the iron block 1222, so that the adjacent upper wind-blocking sliding plates 121 slide towards the two sides of the driving head 1221 along the upper sliding rails 103, respectively, and the first upper wind outlet 101 and the first lower wind outlet 102 are blocked. The lower wind-shielding sliding plate 22 slides downwards along the lower sliding rail 203 due to gravity, so that the second upper wind outlet 201 is shielded, the second lower wind outlet 202 is communicated with the outside, and the wind outlet direction is opposite to the face. When the switch is pressed down, air enters through the air inlet 104 and sequentially passes through the upper connecting portion 11 and the lower connecting portion 21, and then is blown to the face from the second lower air outlet 202, so that air circulation near the face is accelerated, and the temperature is reduced. The main body part 10 is taken down, the second upper air outlet 101 is located below, the external part 10 is worn on the neck, and the lower wind-blocking sliding plate 22 slides downwards, so that the second lower air outlet 202 is blocked, and at the moment, air is blown out to the face part through the second upper air outlet 201. Because the opening area of air outlet 201 is different under second air outlet 202 and the second for the area difference of blowing of face is the circulation of air speed difference promptly, thereby makes the cooling effect different, through wearing or wearing main part 10 conversely, can realize the regulation of cooling effect. The switch is pressed again and the centrifugal fan 5 stops rotating.

The magnetically attracted lower connection ring 211 and the upper connection ring 111 are magnetically attracted to each other to be fixed relatively, meanwhile, the protrusion 2111 enters the upper connection ring 111 upwards and abuts against the self-resetting sealing plate 112, so that the self-resetting sealing plate 112 is rotated and opened, the electrode a111 is conducted with the electrode b2121, and the main body 10 is communicated with the inside of the external part 20. When the switch is pressed, the control module 3 controls the centrifugal fan 5 to rotate and simultaneously enables the atomizer 60 to start working, the atomizing nozzle 602 sprays atomized water to the neck through the atomizing nozzle 205, and the ambient temperature is reduced due to evaporation and heat absorption. The main body 10 is turned over with the external portion 10 removed, so that the atomizing nozzle 205 faces the face, and the atomizing direction is adjusted. And pressing the switch again, the control module 3 controls the centrifugal fan 5 and the atomizer 60 to stop working. When the atomization blowing function is used, the face blowing function is synchronously performed, and the process is as described above, so that the repeated description is omitted.
