[0013] As an improvement to the waterproof built-in air pump of this utility model, the touch switch is used to control the working state of the pump core. Touching the touch switch once turns the pump core into the power-on state, and touching the touch switch twice turns the pump core into the power-off state. The number of touches required to turn on and off can be set as needed.

[0014] The beneficial effects of this utility model are as follows: This utility model has a waterproof function. It achieves the waterproof function of the built-in air pump by using the sealing connection between the sealing cover and the air inlet connection seat and the racetrack-shaped sealing ring set on the edge of the cover.
