The hand holds the outer cover body 31 and makes to air-dry the transmission post 62 just right with the drive post 21, places interior casing 10 upper end with interior lid 30, and interior casing 10 upper end and interior lid 30 lower extreme are provided with the permanent magnet that can each other magnetism inhale respectively, and the permanent magnet is inhaled each other magnetism and is made interior casing 10 upper end and interior lid 30 lower extreme counterbalance tightly. Meanwhile, the two positioning protruding strips 105 at the upper end of the inner shell 10 enter the air-drying positioning grooves 302 at the lower end of the inner cover 30 respectively, so that the inner shell 10 and the outer cover 31 cannot rotate relatively, and the inner shell 10 and the cover 30 are fixed relatively. Then the hand grips outer cup 11, inserts outer cup 11 with interior casing 10 in for both compress tightly each other, joint strip 111 and joint groove 107 joint, thereby make outer cup 11 and interior casing 10 relatively fixed, occupy small after accomodating the completion of this product, the outward appearance rule is convenient for hand-carry.

Often adhere to moisture content on outer cup 11 and the brush head 5, breed the bacterium easily, when using this product air-dry function, interior casing 10 and interior cover 30 magnetism each other inhale for air-dry drive column 62 supports tightly with drive column 21, air-dry spring 63 compression. Simultaneously button 22 offsets with pressing the briquetting 12, presses briquetting 12 to the inboard and makes pressing briquetting 12 press button 22, and the motor begins to rotate, and drive post 21 rotates with air-dry transmission post 62 relatively, and when drive post 21 rotate to just right to air-dry driven hole 622, air-dry transmission post 62 is to drive post 21 direction motion under the elastic force effect of air-dry spring 63, and then makes drive post 21 enter into air-dry driven hole 622, and drive post 21 can drive air-dry driven hole 622. Air-dry driven hole 622 rotates and makes air-dry drive post 62 rotate, and air-dry drive post 62 rotates and makes slip post 621 drive slip through-hole 613 rotate, makes then air-dry rotating tube 61 rotate, and air-dry rotating tube 61 rotates and air-dries rotating tube 601 through first hold-in range drive and rotates, and then makes air-dry fan 60 rotate. At this time, the synchronous transmission gear 71 is not in contact with the end face gear 721, the drying fan 60 cannot drive the blowing fan 70 to rotate when rotating, only the drying fan 60 rotates, the torque output by the driving post 21 can be converted into power for driving the drying fan 60 to rotate with the maximum efficiency, and the energy utilization rate is higher. The external air enters the brush head chamber 102 through the air inlet 311 and the upper vent 3011 in sequence under the rotation of the air drying fan 60, and then the air in the brush head chamber 102 enters the outer cup 11 through the lower vent 1021 and the air outlet 104. When the clamping bar 111 is clamped with the clamping groove 107, the spacing block 112 abuts against the outer wall of the inner shell 10, so that a gap is formed between the outer cup body 11 and the inner shell 10, and air entering the outer cup body 11 fills the outer cup body 11 and can escape to the outside through the gap between the outer cup body 11 and the inner shell 10. With the continued rotation of the drying fan 60, the air circulation will cause the water attached to the brush head 5 and the outer casing 11 to evaporate rapidly, and the evaporated water vapor escapes outwards along with the air circulation. Therefore, the interior of the outer cup body 11, the brush head bin 102 and the brush head 5 are kept in a relatively dry environment, bacteria breeding is avoided, the sanitation of the outer cup body 11 and the brush head 5 is kept, and the health of a user is benefited. After the air drying is finished, the pressing block 12 is pressed again, the button 22 is pressed by the pressing block 12, and the motor stops rotating.

The product also has a blowing function, when in use, the inner shell 10 is held by hands, the outer cover body 31 is taken down, the driving column 21 faces upwards, and the outer cover body 31 is adjusted, so that the outer insertion hole 313 is opposite to the driving column 21 (as shown in fig. 15). The driving column 21 is inserted into the outer insertion hole 313, and the outer cover 31 is pressed downward, so that the positioning protruding strips 105 close to the driving column 21 enter the blowing positioning grooves 314, the outer cover 31 and the inner housing 10 cannot rotate relatively, and at the same time, the permanent magnets attract each other, and the outer cover 31 and the inner housing 10 are fixed relatively. At this time, the driving post 21 abuts against the blowing transmission post 711, and at the same time, the blowing spring 74 is compressed, and the pressing block 12 is pressed to press the button 22, so that the motor starts to rotate, and the driving post 21 and the blowing transmission post 711 rotate relatively. When the driving post 21 rotates to be aligned with the blowing driven hole 7111, the blowing transmission post 711 moves downwards under the elastic force of the blowing spring 74, the driving post 21 enters the blowing driven hole 7111, and the driving post 21 rotates to drive the blowing transmission post 711 to rotate. The rotation of the blowing transmission post 7111 makes the synchronous transmission gear 71 rotate, the synchronous transmission gear 71 rotates to drive the end face gears 721 at two sides of the synchronous transmission gear to rotate, i.e. the transmission shafts 72 at two sides of the synchronous transmission gear 71 rotate, and the transmission shafts 72 rotate to drive the corresponding transmission gears 73 to rotate so as to synchronously rotate the two synchronous belt disks 73. The two synchronous reels 73 are respectively in transmission connection with the air drying fan 60 and the air blowing fan 70 through two synchronous belts, and the two synchronous reels 73 rotate to enable the air drying fan 60 and the air blowing fan 70 to synchronously rotate towards the same direction. Air flows in through the air inlet 311 under the driving of the blades, is blown out through the upper air vent 3011, and is blown by adjusting the orientation of the upper air vent 3011.

The pressing block 12 is pressed again, the motor stops rotating, the outer cover 31 is pulled down, the outer cover 31 is adjusted to enable the air drying transmission column 62 to be opposite to the driving column 21, the outer cover 31 is placed at the upper end of the inner shell 10 again, and the outer cover 31 and the inner shell 10 are fixed relatively.
