The pump body of the present invention can be an external independent pump, or it can be built into items such as a mattress, an air cushion craft, a life buoy, etc.), turn on the inflation button or the exhaust button of the control button as needed. When inflating, turn on the inflation button, turn on the power supply, and the control module controls the second drive motor to operate, driving the fan gear to rotate so that the inflation stroke switch senses a signal that the valve plate is in place, and then stops the operation of the second drive motor, so that the air inlet passes through the intake flow channel and then through the three-way valve assembly to connect to the air inlet end of the fan, and the air outlet end of the fan is synchronously connected to the inner chamber of the shell through the three-way valve assembly; the control module then controls the rotation of the first drive motor, and the first drive motor simultaneously drives the fan and the hydraulic valve assembly to operate synchronously, and the hydraulic valve assembly The impeller rotates to push the hydraulic oil in the cylinder body, and the hydraulic oil gives the cylinder body a downward thrust, which overcomes the supporting force of the spring, and the cylinder body brings the valve stem to push the valve disc and the valve seat at the lower end of the shell to separate, so that the closed chamber in the shell and the lower end surface of the shell are connected to form an airway, that is, the chamber in the shell is connected to the inflatable space of the mattress, air cushion boat, life buoy and other items, and the fan is driven to rotate synchronously, and the fan connects the air inlet to the outside air to the inner chamber of the shell through the inlet airway, and then transmits it to the internal space of the mattress, air cushion boat, life buoy and other items through the airway between the valve disc at the lower end of the pump and the shell, so as to achieve rapid inflation. After the inflation is completed, the inflation button is turned off, the power supply is disconnected, the first drive motor stops, the impeller stops rotating, and the cylinder body is no longer subjected to the downward hydraulic thrust, then the spring supports the cylinder body to reset upward, so that the valve disc and the valve seat at the lower end of the shell are closed, effectively preventing the inflation space of the mattress, air cushion boat, life buoy and other items from being connected to the outside, resulting in air leakage; When exhaust is needed, the exhaust button is turned on, the power is turned on, and the control module controls the second drive motor to drive the fan gear to rotate so that the exhaust stroke switch senses the signal that the valve plate is in place, and then stops the operation of the second drive motor, so that the inner chamber of the shell is connected to the air inlet end of the fan through the three-way valve assembly, and the air outlet end of the fan is connected to the exhaust port at the upper end of the shell through the exhaust flow channel connected to the three-way valve assembly; the control module then controls the rotation of the first drive motor, and the first drive motor drives the fan and the hydraulic valve assembly to move synchronously at the same time, and the impeller of the hydraulic valve assembly rotates to push the hydraulic oil in the cylinder body, and the cylinder body is given a downward thrust through the hydraulic oil, and the thrust overcomes the supporting force of the spring. , the cylinder body carries the valve stem to push the valve disc and the valve seat at the lower end of the shell body to separate, so that the closed chamber in the shell body is connected to the lower end surface of the shell body to form an airway, that is, the chamber in the shell body is connected to the exhaust space of items such as mattresses, hovercrafts, lifebuoys, etc., and the airflow in the exhaust space flows into the inner chamber of the shell body, and the fan is driven to rotate synchronously. The fan actively discharges the gas in the inner chamber of the shell body to the outside world connected to the exhaust port at the upper end of the shell through the three-way valve assembly to achieve rapid exhaust.
