The umbrella further comprises an inflatable body communicated with the air pump 107, the air pump 107 is fixedly arranged at the top end of the umbrella rod 106 and is communicated with the inflatable body, specifically, an inflation (exhaust) port of the air pump 107 is communicated with an inner cavity of the inflatable body, and the communication position is sealed.

In this example, the inflatable body includes a central area 104 connected to the air pump 107, eight arms 102 are uniformly distributed around the central area 104, and the roots of the arms 102 are connected to the central area so that the whole inflatable body has integral air storage chambers which are connected to each other for inflation and deflation. The free end of arm 102 is fixedly connected to the outer periphery of canopy 101 at connection point 103. Can realize the firmer umbrella surface supporting function with less inflation quantity. The less inflation volume can reduce the workload of using the manual air pump, and can reduce the power consumption of the electric air pump.

The center of the inflatable body and the center of the umbrella cover 101 are fixedly connected with an umbrella rod 106; in this example, eight connection points 103 are arranged around the outer side of the inflatable body and fixedly connected with the outer periphery of the umbrella cover 101; in the case of a central fixed connection, these eight points of attachment 103 in this example allow the inflatable body to support and stretch open the entire canopy 101 when inflated.

In fact, the structure of the inflatable body in this example adopts the structure a, except for eight connection points 103, the outer periphery of the octagonal star of the inflatable body is all fixedly connected with the umbrella cover through hot melting, but the hot melting fixed part is not positioned on the outer periphery of the umbrella cover 101, but positioned inside the umbrella cover 101.

In other embodiments, the connection point 103 may be configured in various other ways by changing the shape of the inflatable body, etc., to support and stretch the entire canopy.

In this example, the structure of the inflatable body adopts a structure A: the inflatable body is an air storage cavity formed by airtight cloth and an umbrella cover 101; the umbrella surface 101 and the airtight cloth are made of PVC plastic cloth, the airtight cloth is in an octagonal shape, the umbrella surface 101 is in a regular octagon shape, the periphery of the airtight cloth is connected and attached to the lower surface of the umbrella surface 101 through hot melting, and an airtight air storage cavity is formed between the umbrella surface 101 and the airtight cloth. The air storage cavity formed by the cloth cover is convenient for being collected and mixed into a ball after air is discharged.

In this example, in order to make canopy 101 have a shape with a lower outer side, rainwater is guided to fall so as not to be accumulated on canopy 101.

Example 2: referring to fig. 5, the difference from embodiment 1 is that the inflatable body has a different shape, and is composed of a central area 204 having a circular shape and four arms 201 having a trapezoidal shape. In this embodiment, four linear connection points 203 are provided around the outer side of the inflatable body and are fixedly connected to the outer periphery of the umbrella cover 202.

Example 3: referring to fig. 6 and 7, the difference from embodiment 1 is that the structure of the inflatable body in this embodiment adopts a structure B, the inflatable body 303 is a gas storage cavity formed by airtight cloth alone, and the umbrella cover 301 does not need to adopt airtight cloth.

In this example, the center of inflatable body 303 and the center of canopy 301 are both fixed with the umbrella pole, but the fixed points of both have a height difference, and inflatable body 303 pulls the outer side of canopy 301 to incline downwards after inflation to guide rainwater to flow downwards. The shape of the inflatable body 303 can adopt the shape of embodiment 1 and/or embodiment 2, or other shapes can achieve the purpose of the invention.

In this example, the inflation mechanism employs a rechargeable battery-powered pump 305 for both inflation and deflation, and the pump 305 is disposed at the umbrella handle 306 and is connected to the inflatable body 303 through an air guide channel disposed in the umbrella handle. The umbrella rod is a telescopic rod formed by an outer tube 302 and an inner tube 304, inner cavities of the outer tube 302 and the inner tube 304 are communicated to form the air guide channel, and a sealing ring 308 is arranged at the joint of the outer tube 302 and the inner tube 304.
