[0017] In order to make the technical solution of the present invention more clear and specific to those skilled in the art, the present invention is further described in detail below with reference to embodiments and drawings, but the embodiments of the present invention are not limited thereto.

[0018] like Figure 1-Figure 3 As shown, the inflation cylinder device provided by this embodiment includes a cylinder body 3, a heart-through valve core 2 is installed in the cylinder body 3, the heart-through valve core 2 passes through the cylinder body 3, and an inflation adapter 5 and an inflation nozzle 1 are respectively provided on both sides of the heart-through valve core 2. A vent hole 6 is provided on one side of the cylinder body 3, and the vent hole 6 is connected with the heart-through valve core 2. The up and down movement of the heart-through valve core can be realized with the help of a solenoid valve and an air source. The structure is integrated, simple and easy to maintain, the processing cost is greatly reduced, the assembly space is small, the installation is more flexible, the valve body and valve core are tightly matched, and the positioning accuracy is high.

[0019] In this embodiment, if Figure 1 As shown, an inner groove is provided in the cylinder body 3, the through-heart valve core 2 is arranged on the inner groove of the cylinder body 3 and is clamped in the cylinder body 3, and a limiting sealing ring 4 is provided between the through-heart valve core 2 and the cylinder body 3. The through-heart valve core is sealed and limited by means of the inner groove of the cylinder body and the limiting sealing ring 4.

[0020] In this embodiment, if Figure 1 As shown, one end of the core valve core 2 connected to the inflation nozzle 1 has a slot, and the core valve core 2 and the inflation nozzle 1 are snap-fitted together through the slot, which facilitates the quick installation of the inflation nozzle 1 and prevents it from falling off.
