Technical Problem
[0004]现有的内置式的双向气泵通常是在双向气泵上设置防漏气装置，即充气制品在充满气后的使用过程中，双向气泵不能取出
Benefits of technology
[0016]The inner shell and inner cover of this invention are slidably disposed within the outer shell, allowing for inflation and deflation operations via forward and reverse insertion. After inflation, the airflow within the inflatable product blows the sealing device of the outer shell, restoring it to its original shape and sealing the air vent, preventing air from escaping through the vent. The sealed inner shell and inner cover can be placed within the outer shell or removed for inflating other inflatable products, charging, or maintenance.
