The upper end surface and the lower end surface of the ring switch 99 are provided with several recesses corresponding to the position of the start switch 931 (normally closed switch) of the first switch 97 and the second switch 96 and the motor 93; As shown in Figure 9B, When inflating, the ring switch 99 turns to a certain position, and the concave position 991 on the upper end surface of the ring switch 99 is aligned with the second switch 96 so that the second switch 96 is closed; at the same time, the lower end surface of the ring switch 99 pushes the first switch 97 back; and The recess 992 on the lower end surface of the ring switch 99 is aligned with the motor start switch 931 and released into the start switch 931; at this time, the motor 93 drives the bellows 94 through the gear 901 and the connecting rod 902, and the outside air passes through the first switch 97 and the third switch 98 is pumped into the inflatable umbrella handle 92, and the air-flow direction is as shown by the arrow among the figures.

If you want to stop inflation, turn the ring switch 99 to the position shown in Figure 9C, the concave position 991 on the upper end surface of the ring switch 99 is still aligned with the second switch 96, so that the second switch 96 is closed; meanwhile, the bottom of the ring switch 99 Another recess 994 of the end face is aligned with the first switch 97, so that the first switch 97 is closed; and the ring switch 99 lower end face withstands the motor start switch 931 and closes the start switch 931 to stop the motor 93.

If you want to deflate, turn the ring switch 99 to the position shown in Fig. 9D, the upper end face of the ring switch 99 pushes away the second switch 96; the recess 994 on the lower end face of the ring switch 99 is still aligned with the first switch 97, so that The first day off 97 closed; And ring switch 99 lower end faces still withstood the motor start switch 931 and closed start start 931 stops motor 93. The inflatable umbrella handle 92 automatically flows out through the second switch 96, and the airflow direction is shown by the arrow among the figures.

10A to 10B have introduced the tenth embodiment of the present invention: it is an inflatable umbrella, here, the air pump that comprises bellows 94, connecting rod 902, gear 901 and motor 93 used in the ninth embodiment is Another kind of air pump 150 replaces; Air pump 150 comprises a cylindrical housing 151, a fan 155 eccentrically installed in the housing 151 and a motor 154 mounted on the outside of the housing 151 to drive the fan 155; There is an air inlet 152 communicating with the first switch 97 and an air outlet 153 communicating with the third switch 158 . During operation, air is pumped into the casing 151 through the air inlet 152 , and then pumped out of the casing 151 through the air outlet 153 . The fan 155 is eccentrically installed in the housing 151, effectively ensuring the air pressure for the umbrella to be inflated.

It can be known from common technical knowledge that the present invention can be realized through other embodiments without departing from its spirit or essential features. Accordingly, the above-disclosed embodiments are, in all respects, illustrative and not exclusive. All changes within the scope of the present invention or within the scope equivalent to the present invention are embraced by the present invention.
