[0050] When the spring pin 56 is placed in the second positioning groove 18, the pump is in a closed state, and the sealing plate 524 on the lower slide 52 blocks the first vent 13. In order to ensure the airtightness of the first vent 13 when it is in a closed state, a mounting groove is provided on the outer periphery of the first vent 13, and a sealing gasket 131 is installed in the mounting groove, and the sealing gasket 131 can abut against the sealing plate 524.

[0051] When the spring pin 56 is placed in the third positioning groove 19, the pump is in the deflated state, the lower port of the second switching channel 523 is connected to the first vent 13 and communicated, and at the same time, the blocking plate 525 on the lower slide 52 will block the opening 513 on the upper slide 51, and the lower end opening of the air outlet 442 of the upper slide 51 is suspended in the air and is not blocked by the lower slide 52, that is, the air outlet 442 of the upper slide 51 is connected to the inner cavity of the body 10. The motor 41 is turned on, and the gas inside the inflatable product is pumped out to the outside through the first vent 13, the second switching channel 523, the air inlet 441, the pump chamber 45, the air outlet 442, the body chamber 12, and the second vent 21 in sequence.

[0052] The pump will start the motor 41 in both the inflation state and the deflation state to achieve rapid inflation and deflation. When there is no power supply or the motor 41 cannot work, ensure that the sealing plate 524 blocks the first vent 13, then pull out the valve plug 80, and then the inflatable product can be inflated through the inflation channel 15 with the help of an external inflation device (a manual pump or an electric pump); for deflation, rotate the hand wheel 54 so that the spring pin 56 is placed in the third positioning groove 19, and then deflation can be achieved, and deflation can also be assisted by squeezing the inflatable product.
