In one embodiment, as shown in figures 23 to 25, and in connection with the corresponding figures, the ends of each arm 28 are respectively formed with a sphere 29 that cooperates with the positioning circular arc 27.

It can be understood that, through the above structure, when the rotary fan 2 rotates unidirectionally, the air flow discharged by the second centrifugal fan blade 8 in the rotation process can enter the first centrifugal fan blade 7 through the ventilation gap 43, so that the air flow can be smoothly discharged to the periphery, and the center of the second centrifugal fan blade 8 can be ensured to normally form negative pressure, thereby realizing external air suction. Therefore, when the rotary fan 2 rotates unidirectionally, the technical effects that the front face of the rotary fan is exhausted outwards, and the back face of the rotary fan is sucked outwards can be finally realized, so that the technical effects to be achieved by the air pump are effectively ensured.

When the inflatable product needs to be inflated, the air pump needs to be switched to an inflated state, as shown in fig. 11, 26, 27, 28 and 29 and combined with the corresponding drawings, the manual control knob 13 is rotated clockwise, so that the handle on the control knob 13 corresponds to the inflation gear 36 on the panel 34, the ventilation drum 3 is rotated clockwise, the ventilation port 4 is communicated with the inflation port 5, and synchronously, the V-shaped groove 19 in the ventilation drum 3 drives and guides the shoulder plate 18 to move to the groove 38 at the end of the V-shaped groove 19, so that the movable plate 17 drives the valve plate 16 to generate axial movement, the valve plate 16 is far away from the orifice of the ventilation drum 3, the valve plate 16 is opened from the through hole 22, and the ventilation drum 3 is switched to a conducting state. Meanwhile, the first pulling piece 14 on the side wall of the control knob 13 also triggers the starting switch 12, so that the motor 32 drives the rotary fan 2 to rotate, and air flow generated from one side of the first centrifugal fan blade 7 can sequentially pass through the air charging port 5, the ventilation interface 4 and the ventilation rotary drum 3, and finally is output to the inside of an inflatable product from the through hole 22 to the outside, so that the inflation function is realized.
When the inflatable product needs to be deflated, the air pump needs to be switched to a deflation state, as shown in fig. 12, 30 and 31 and combined with the corresponding drawings, the manual control knob 13 is rotated anticlockwise, the handle on the control knob 13 corresponds to the deflation gear 37 on the panel 34, at this time, the ventilation drum 3 is also rotated anticlockwise, the ventilation interface 4 is communicated with the deflation port 6, synchronously, the V-shaped groove 19 in the ventilation drum 3 drives and guides the shoulder plate 18 to move to the groove 38 at the other end of the V-shaped groove 19, so that the movable plate 17 drives the valve plate 16 to generate axial movement, the valve plate 16 is far away from the orifice of the ventilation drum 3, the valve plate 16 is opened from the through hole 22, and the ventilation drum 3 is in a conducting state. Meanwhile, the second pulling piece 15 on the side wall of the control knob 13 also triggers the starting switch 12, so that the motor 32 drives the rotary fan 2 to rotate, negative pressure is formed in the ventilation drum 3 because air is continuously sucked by the air suction end of the second centrifugal fan blade 8, the pipe orifice of the ventilation drum 3 can continuously absorb external air, air in an inflating product can enter the ventilation drum 3 through the through hole 22, and the ventilation drum 3 can deflate the inflating product, so that the air leakage function is realized.
