[0031] The inflation tube assembly 140 is rotatably connected to the gas outlet of the inflation core 130 . The inflation tube assembly 140 extends to the outside of the housing 110 . When the inflation core 130 starts to work, the gas generated is inflated through the inflation tube assembly 140 .

[0032] The housing 110 is provided with an indication button. When the controller 120 is powered on, an indication signal is transmitted to the controller 120 by pressing the indication button, so that the controller 120 controls the inflator core 130 to start up.

After the inflation is completed, the inflatable tube assembly 140 is rotated relative to the housing 110, and the inflatable tube assembly 140 is switched from the on position to the off position, so that the controller 120 controls the inflatable mechanism 130 to turn off according to the indication signal.

[0035] The inflatable device 100 provided in the present application includes a shell 110, and a controller 120 and an inflatable movement 130 arranged in the shell 110 and electrically connected to each other. An inflatable tube assembly 140 that can be rotatably switched between an off position and an on position is rotatably arranged on the shell 110, and the inflatable tube assembly 140 is connected to an air outlet of the inflatable movement 130. A trigger assembly 150 electrically connected to the controller 120 is arranged in the shell 110.

After the inflation is completed, the inflatable tube assembly 140 is rotated relative to the housing 110. When the inflatable tube assembly 140 is switched from the on position to the off position, the magnetic field strength detected by the Hall switch is less than the trigger value, and the controller 120 controls the inflatable movement 130 to turn off according to the trigger signal of the Hall switch.

[0049] Specifically, when the inflatable tube 142 is rotated, the elastic limiting member 111 switches in sequence in the plurality of tooth-shaped grooves 1422 , so as to provide a blocking force when the inflatable tube 142 is rotated, thereby preventing the inflatable tube 142 from self-rotating.

[0050] In a feasible embodiment of the present application, Figure 1 , Figure 2 , Figure 3 and Figure 4 As shown, a limiting portion 1421 is provided at one end of the inflation tube 142 extending out of the shell 110 , and the limiting portion 1421 abuts against the outer wall of the shell 110 .

The controller 120 is used to use the ambient atmospheric pressure value as the initial value for inflation, and then the inflatable mechanism 130 starts to work to inflate the inflatable article through the inflatable tube assembly 140. After inflation is completed, the inflatable tube assembly 140 is rotated relative to the housing 110, and the inflatable tube assembly 140 is switched from the on position to the off position, so that the controller 120 controls the inflatable mechanism 130 to turn off according to the indication signal.
