[0035] Figures 1 to 8 An embodiment of the hot air drying device for transdermal patches of the present utility model is shown. The hot air drying device for transdermal patches in this embodiment includes at least one hot air drying module 1. The hot air drying module 1 includes a box body 2. An air inlet chamber 3, a pressure equalizing chamber 5, and a drying chamber 6 are sequentially communicated inside the box body 2. The air inlet chamber 3 and the drying chamber 6 are oppositely arranged on the front and rear sides of the pressure equalizing chamber 5. One end of the drying chamber 6 is provided with a feed inlet 61 and the opposite end is provided with a discharge outlet 62. The air inlet chamber 3 is provided with an air inlet connector 31, a circulation fan 32, and a heating component 4. The drying chamber 6 is provided with an exhaust air connector 63. The exhaust air connector 63 is provided with a return air port (blocked in the figure and not shown), and the return air port is communicated with the air inlet chamber 3. It should be noted that the front side and the rear side are relative. It can be that the air inlet chamber 3 is on the front side and the drying chamber 6 is on the rear side, or the air inlet chamber 3 is on the rear side and the drying chamber 6 is on the front side.

[0036] The hot air drying device for transdermal patches in this embodiment adopts a modular design. Each hot air drying module 1 has independent components such as a circulation fan 32, a heating component 4, a pressure equalizing chamber 5, and a drying chamber 6, etc., which is convenient for independently controlling parameters such as the temperature, air pressure, air velocity, and circulating air volume of each hot air drying module 1, so as to meet the requirements of high-standard industries. When the hot air drying module 1 works, external cold air enters the air inlet chamber 3 through the air inlet connector 31. The circulation fan 32 provides power for the cold air to circulate. The heating component 4 heats the cold air to the set temperature. The hot air enters the pressure equalizing chamber 5 to complete pressure equalization and then evenly enters the drying chamber 6, which is beneficial to ensuring the temperature consistency in the drying chamber 6. The transdermal patch 8 is fed into the drying chamber 6 from the feed inlet 61 of the drying chamber 6, and is discharged from the discharge outlet 62 of the drying chamber 6 after being dried by the hot air in the drying chamber 6. A part of the hot air after drying is discharged from the exhaust air connector 63, and the other part can enter the air inlet chamber 3 again through the return air port of the exhaust air connector 63 for recycling. The air inlet chamber 3 and the drying chamber 6 are oppositely arranged on the front and rear sides of the pressure equalizing chamber 5, which is convenient for maintaining and replacing components such as the air inlet connector 31, the circulation fan 32, and the heating component 4 in the air inlet chamber 3; and the feed inlet 61 and the discharge outlet 62 are oppositely arranged at both ends of the drying chamber 6, which is beneficial to the combined use of multiple hot air drying modules 1 (specifically refer to Figure 8 , the discharge outlet 62 of the upper and lower two hot air drying modules 1 and the feed inlet 61 are butt-connected end to end), and the layout is reasonable and effective.

After the air outlet of the air inlet chamber 3 enters the pressure equalizing chamber 5, due to the high filtration grade and large flow resistance of the second filter assembly 51, the wind speed is greatly reduced, the pressure in the pressure equalizing chamber 5 increases, and the hot air uniformly passes through the second filter assembly 51, thereby realizing the pressure equalizing effect. At the same time, the second filter assembly 51 can further improve the cleanliness of the hot air and avoid contaminating the transdermal patch 8. Preferably, the volume of the uniform chamber 5 is larger than that of the air inlet chamber 3, which is beneficial to further enhancing the pressure equalizing effect.

During operation, the external cold air enters the air inlet chamber 3 through the air inlet joint 31. The circulation fan 32 provides power for the circulating flow of the cold air. The cold air is first preliminarily filtered by the primary filter 331, then secondarily filtered by the medium - efficiency filter 332, and finally flows to the heating assembly 4 through the air outlet of the circulation fan 32. The heating assembly 4 heats the cold air to the set temperature, and the hot air is further filtered by the high - efficiency filters 511 to improve the cleanliness, thereby avoiding contaminating the transdermal patch 8.
