[0055] The above-mentioned pump-valve integrated pump can inflate, deflate and maintain pressure of the air bag according to actual needs, and can switch between inflation, deflation and pressure maintaining states of different interfaces by controlling the first magnetic control sealing pad 1091 and the second magnetic control sealing pad 1092, which has strong control flexibility.

[0056] When the air bag needs to be inflated, the first magnetic sealing gasket 1091 is controlled to block the seventh interface 1043 and the second magnetic sealing gasket 1092 is controlled to block the eleventh interface 1047 by the controller, the air flow is first controlled to enter the pump from the first interface 1071, sequentially through the second interface 1072, the sixth interface 1042 and the fifth interface 1041 to the inside of the pump, and then the air flow is controlled to exit the pump from the pump, sequentially through the ninth interface 1045, the tenth interface 1046, the fourth interface 1074 and the third interface 1073 to the air bag.

[0057] When the air bag needs to be deflated, the first magnetic sealing gasket 1091 is controlled to block the second interface 1072 and the second magnetic sealing gasket 1092 is controlled to block the fourth interface 1074 by the controller, the air flow is first controlled to enter the pump from the third interface 1073, sequentially through the third air passage C, the eighth interface 1044, the seventh interface 1043, the sixth interface 1042 and the fifth interface 1041 to the inside of the pump, and then the air flow is controlled to exit the pump from the pump, sequentially through the ninth interface 1045, the tenth interface 1046, the eleventh interface 1047 and the twelfth interface 1048 to the atmosphere;

[0058] When the air bag needs to be sealed and pressure maintained, the first magnetic sealing gasket 1091 is controlled to block the seventh interface 1043 and the second magnetic sealing gasket 1092 is controlled to block the fourth interface 1074 by the controller. At this time, the air bag has no gas exchange with the outside atmosphere and the pump, and the air pressure of the air bag can be well maintained.

[0059] The connecting head 122 includes a thirteenth interface 1221, a fourteenth interface 1222, a fifteenth interface 1223, a sixteenth interface 1224 and a seventeenth interface 1225, and the pump includes an air outlet 52 and an air inlet 51 arranged on the upper cover 5. The thirteenth interface 1221 is connected to the ninth interface 1045, the fourteenth interface 1222 is connected to the fifth interface 1041, the fifteenth interface 1223 is connected to the thirteenth interface 1221, the sixteenth interface 1224 is connected to the fourteenth interface 1222, the seventeenth interface 1225 is connected to the thirteenth interface 1221 and the fifteenth interface 1223 respectively, the fifteenth interface 1223 is connected to the air outlet 52, the sixteenth interface 1224 is connected to the air inlet 51, and the seventeenth interface 1225 is provided with a pressure relief assembly.

[0060] The pressure relief assembly installed through the seventeenth interface 1225 can prevent the airbag from being broken due to excessive internal pressure. When the internal pressure of the airbag is too large, the gas in the airbag can be discharged to the atmosphere through the pressure relief assembly installed through the seventeenth interface 1225, thereby relieving the pressure of the airbag. During the operation of the pump-valve integrated pump described above, the gas in the electromagnetic valve can enter the suction pump from the fifth interface 1041, and then sequentially pass through the fourteenth interface 1222, the sixteenth interface 1224, and the gas inlet 51 to enter the suction pump; the gas in the suction pump can enter the electromagnetic valve from the gas outlet 52, and then sequentially pass through the fifteenth interface 1223, the thirteenth interface 1221, and the ninth interface 1045 to enter the electromagnetic valve.

[0061] The pressure relief assembly includes pressure relief sound-absorbing cotton 127, a spiral pressure regulating cap 126, a pressure regulating spring 125, a guide rod 124, and an elastic valve plug 123.

The inner interface 12251 is connected to the outer interface 12252, the thirteenth interface 1221, and the fifteenth interface 1223, respectively. The diameter of the inner interface 12251 is smaller than that of the outer interface 12252. The inner wall of the outer interface 12252 is provided with a threaded structure matched with the spiral pressure regulating cap 126. The spiral pressure regulating cap 126 is provided with a pressure relief through hole 1261 matched with pressure relief. The pressure regulating spring 125 is installed between the spiral pressure regulating cap 126 and the guide rod 124. The pressure relief sound-absorbing cotton 127 is installed at one end of the spiral pressure regulating cap 126 away from the pressure regulating spring 125. The elastic valve plug 123 is arranged between the guide rod 124 and the inner interface 12251.

[0062] The mutual cooperation of the pressure relief sound-absorbing cotton 127, the spiral pressure regulating cap 126, the pressure regulating spring 125, the guide rod 124, and the elastic valve plug 123 can relieve the pressure of the airbag, thereby effectively protecting the airbag from being broken. By loosening the spiral pressure regulating cap 126, the compression amount of the pressure regulating spring 125 can be reduced, the force acting on the elastic valve plug 123 by the pressure regulating spring 125 can be reduced, and the gas can more easily push the elastic valve plug 123 to the spiral pressure regulating cap 126 through the inner interface 12251 to achieve pressure relief, thereby reducing the pressure threshold of pressure relief. By tightening the spiral pressure regulating cap 126, the compression amount of the pressure regulating spring 125 can be increased, the force acting on the elastic valve plug 123 by the pressure regulating spring 125 can be increased, and the difficulty of pushing the elastic valve plug 123 to the spiral pressure regulating cap 126 through the inner interface 12251 by the gas can be increased, thereby increasing the pressure threshold of pressure relief.

[0063] The moving iron core 110 includes a first moving iron core and a second moving iron core, the static iron core 114 includes a first static iron core and a second static iron core, the coil 117 includes a first coil and a second coil, the control spring 113 includes a first control spring and a second control spring, the first moving iron core is connected with the first magnetic control sealing gasket 1091, and the second moving iron core is connected with the second magnetic control sealing gasket 1092; the first moving iron core, the first static iron core and the first control spring are arranged inside the first coil, and the first control spring is arranged between the first moving iron core and the first static iron core; the second moving iron core, the second static iron core and the second control spring are arranged inside the second coil, and the second control spring is arranged between the second moving iron core and the second static iron core.

[0064] After the first coil is powered on, the first moving iron core and the first static iron core are magnetized by the magnetic field generated by the first coil, so that the first moving iron core drives the first magnetic control sealing gasket 1091 to move towards the first static iron core, and the first control spring is compressed, at this time, the second interface 1072 is blocked by the first magnetic control sealing gasket 1091; after the first coil is powered off, the first moving iron core and the first static iron core no longer attract each other, and the first moving iron core resets under the action of the first control spring, at this time, the seventh interface 1043 is blocked. After the second coil is powered on, the second moving iron core and the second static iron core are magnetized by the magnetic field generated by the second coil, so that the second moving iron core drives the second magnetic control sealing gasket 1092 to move towards the second static iron core, and the second control spring is compressed, at this time, the fourth interface 1074 is blocked by the second magnetic control sealing gasket 1092; after the second coil is powered off, the second moving iron core and the second static iron core no longer attract each other, and the second moving iron core resets under the action of the second control spring, at this time, the eleventh interface 1047 is blocked. It can be seen that by controlling the power-on and power-off of the first coil and the second coil, the control of the opening and closing of the interface can be realized, and then the pump-valve integrated pump can be switched between the inflation state, the exhaust state and the pressure maintaining state.

[0065] Further, the first sound-absorbing cotton 120 is mounted outside the first interface 1071, and the lower air nozzle 107 is provided with a support frame matched with the first sound-absorbing cotton 120. By arranging the first sound-absorbing cotton 120, the lower air nozzle 107 will not produce noise when it inhales air through the first interface 1071, and the fine pores of the first sound-absorbing cotton 120 can differentiate and attenuate the airflow, thereby reducing the noise of the airflow. The support frame of the lower air nozzle 107 can fix the first sound-absorbing cotton 120.

[0066] Further, the second sound-absorbing cotton 103 is mounted outside the twelfth interface 1048.
