[0032] The electric inflatable device of the present invention is provided with an internal mounting frame 3 in the housing 1, wherein the air pump 2 is mounted on the side of the internal mounting frame 3 facing the first housing 11, and the internal mounting frame 3 is respectively connected to the first housing 11 and the second housing 12 to form a positioning. In this way, the internal mounting frame 3, the first housing 11 and the second housing 12 are connected and combined into a whole, thereby improving the assembly stability among the three. At the same time, the first housing 11 and the internal mounting frame 3 are respectively clamped on both sides of the air pump 2, thereby forming an all-round positioning for the air pump 2. The connection with the first housing 11 and the second housing 12 can be limited and fixed on both sides of the internal mounting frame 3, thereby improving the installation firmness of the internal mounting frame 3.

[0033] Specifically, the air pump 2 is connected to the air tube 4, and the air is inflated through the air tube 4 to inflate the pneumatic tire, the air mattress, etc. A storage cavity is provided at the rear end of the shell 1, and the air tube 4 is led out from the installation cavity 13 to the storage cavity. When in use, the air tube 4 is pulled out from the storage cavity to inflate. After use, the air tube 4 can be rolled up in the storage cavity. The electric inflatable device also includes a power cord 5, and the electric inflatable device is connected to the power supply through the power cord 5. Of course, a rechargeable battery pack 6 can also be provided in the shell 1, and the battery pack 6 is used to supply power to achieve normal use in scenarios where electricity cannot be connected.

[0034] Specifically, further combining Figures 5 to 7 As shown, the mounting frame 3 is provided with a first stud 31 extending toward the first housing 11. A second stud 111 is provided on the first housing 11 corresponding to the first stud 31. The first stud 31 and the second stud 111 are fixed together by screws.
