[0031] Example 1: This hand dryer is provided with a surround-type air outlet structure. The rotating ring 9 is driven by the rotating circle 7 to rotate, so that the air is discharged in a surround manner and the drying is more comprehensive. Specifically:
[0032] The lower surface of the shell 1 is fixedly connected to the connecting shell 2, and the fixed shell 3 is fixedly installed on the rear surface of the inner wall of the shell 1. A surround-type air outlet structure is installed inside the shell 1. The surround-type air outlet structure can drive the rotating ring 9 to rotate and blow air while rotating the rotating circle 7. The surround-type air outlet structure includes a motor 4, which is fixedly installed on the rear surface of the inner wall of the fixed shell 3. The front end shaft of the motor 4 is fixedly connected to the fan 5. The front surface of the fixed shell 3 is set to an open state, and the opening is fixedly installed with a heating wire 6. The outer surface of the fixed shell 3 is rotatably connected to the rotating circle 7. The front surface of the rotating circle 7 A connecting pipe 8 is connected through the surface, and the other end of the connecting pipe 8 is fixedly connected to a rotating ring 9. The inner wall surface of the rotating ring 9 is provided with air outlets 10 at equal intervals. The outer surface of the rotating circle 7 is provided with a gear block, and the lower side of the rotating circle 7 is meshed with a gear 12. The rear surface of the gear 12 is fixedly connected to the rotating shaft of the motor 2 11, and the motor 2 11 is fixedly installed on the rear surface of the inner wall of the connecting shell 2. An infrared proximity sensor 13 is installed on the upper surface of the inner wall of the outer shell 1. The front surface of the outer shell 1 is provided with an opening, which corresponds to the inner ring of the rotating ring 9. Two connecting pipes 8 are symmetrically provided;
[0033] When the hand dryer is blowing air, first, Figure 1 As shown, when the infrared proximity sensor 13 senses the approach of the hands, the motor 14 installed on the rear surface of the inner wall of the fixed shell 3 will be turned on, and then the motor 14 will drive the fan 5 to rotate. Since the front surface of the fixed shell 3 is set to an open state and the opening is fixedly installed with a heating wire 6, the heating wire 6 is turned on to heat the air, so that the fan 5 blows a hot air flow, as shown in FIG. Figure 4 As shown, the airflow will flow through the connecting pipe 8 connected to the front surface of the rotating ring 7, and then enter the rotating ring 9. Since the inner wall surface of the rotating ring 9 is evenly spaced with air outlets 10, the airflow will be blown out in all directions. Further, as shown in FIG. Figure 3 As shown, a connecting shell 2 is connected to the lower surface of the outer shell 1, and a motor 2 11 is installed on the rear surface of the inner wall of the connecting shell 2.
