[0021] In this embodiment, the outer shell 1 is fixedly connected to the inflatable product, and the inner shell 4 is detachably disposed in the inflation and deflation passage 2 .

[0022] When the inflation port 6 of the inner shell 4 is upward and the deflation port 7 is downward, and inserted into the inflation and deflation channel 2, the combined single-body bidirectional inflation and deflation pump of the utility model is in an inflation state. At this time, the limiting device 9 cooperates with the inner shell 4 to fix its position. Start the inflation and deflation motor 5, and the outside air enters the inflation and deflation motor 5 through the inflation port 6, and then is discharged from the deflation port 7. Under the impact of the air flow, the anti-leakage device 3 opens, and the outside air enters the inflatable product for inflation. Turn off the inflation and deflation motor 5, the air flow no longer impacts the anti-leakage device 3, the anti-leakage device 3 is closed, and the gas in the inflatable product cannot be discharged from the inflation and deflation channel 2.

[0023] When the inflation port 6 of the inner shell 4 is downward and the deflation port 7 is upward, and the inner shell 4 is inserted into the inflation and deflation passage 2, the combined single-body bidirectional inflation and deflation pump of the present invention is in the deflation state. At this time, the pressure ring 8 squeezes the anti-leakage device 3 and opens it, and the limit device 9 cooperates with the inner shell 4 to fix its position. The inflation and deflation motor 5 is started, and the gas in the inflatable product enters the inflation and deflation motor 5 through the inflation port 6 and is then discharged to the outside through the deflation port 7. After deflation is completed, the inflation and deflation motor 5 is turned off.

[0024] The limiting device 9 includes a limiting spring 92 and a limiting rod 93. A plurality of limiting grooves 91 are evenly provided on the outer shell 1 above the charging and discharging channel 2. A limiting spring 92 is arranged in the limiting groove 91. The limiting rod 93 is slidably arranged in the limiting groove 91. One end of the limiting rod 93 is fixedly connected to the limiting spring 92, and the other end of the limiting rod 93 extends into the charging and discharging channel 2 and is fixedly provided with an arc-shaped guide head 94 that contacts and cooperates with the inner shell 4.

[0025] In this embodiment, when the inner shell 4 is installed into the inflation and deflation channel 2, the inner shell 4 squeezes the arc-shaped guide head 94, and the limiting rod 93 squeezes the limiting spring 92 inward to shrink it, and the arc-shaped guide head 94 is squeezed into the limiting groove 91. After the inner shell 4 is installed in place, the inner shell 4 no longer squeezes the arc-shaped guide head 94, the limiting spring 92 extends, and the limiting rod 93 and the arc-shaped guide head 94 move outward and contact the end face of the inner shell 4 to limit their position.

[0026] The anti-leakage device 3 includes a mounting seat 31, a valve stem 33 and a silicone valve disc 36. The mounting seat 31 is arranged at the lower part of the inflation and discharge channel 2 and is fixedly connected to the outer shell 1. A valve stem hole 32 is opened in the middle of the mounting seat 31. The silicone valve disc 36 is arranged below the mounting seat 31 and seals with the inflation and discharge channel 2. A valve stem 33 is fixedly set at the top center of the silicone valve disc 36. The valve stem 33 passes through the valve stem hole 32 and is slidably connected to it. A pressure seat 34 is fixedly set on the top of the valve stem 33. A compression spring 35 is provided on the outside of the valve stem 33 between the pressure seat 34 and the mounting seat 31.

[0027] In the embodiment, when the combined single-body bidirectional inflation and deflation pump is in the inflation state, the end face of the inner housing 4 provided with the deflation port 7 is not in contact with the pressure seat 34. The inflation and deflation motor 5 is started, the external air enters the inflation and deflation motor 5 through the inflation port 6, and then is discharged from the deflation port 7. The air flow passes through the inflation and deflation hole 37 to impact the silica gel valve plate 36, so that the silica gel valve plate 36 is deformed. The external air enters the inflation product to inflate. The inflation and deflation motor 5 is closed, the air flow no longer impacts the silica gel valve plate 36, and the air pressure of the inflation product makes the silica gel valve plate 36 return to the original state and close the inflation and deflation channel 2. The gas in the inflation product cannot be discharged from the inflation and deflation channel 2.

[0028] When the combined single-body bidirectional inflation and deflation pump is in the deflation state, the compression ring 8 extrudes the pressure seat 34, the compression spring 35 is contracted, the pressure seat 34, the valve rod 33 and the silica gel valve plate 36 are synchronously moved downward, and the silica gel valve plate 36 no longer seals the inflation and deflation channel 2. The inflation and deflation motor 5 is started, the gas in the inflation product enters the inflation and deflation channel 2 through the gap between the silica gel valve plate 36 and the outer housing 1, and enters the inflation port 6 through the inflation and deflation hole 37. The gas is discharged from the deflation port 7 to the outside through the inflation and deflation motor 5, and is deflated.

[0029] The middle part of the inflation and deflation channel 2 is provided with a sealing ring 11 matched with the inner housing 4. The sealing ring 11 is located at the upper part of the mounting seat 21 and is fixedly connected with the outer housing 1.

[0030] In the embodiment, the sealing ring 11 is arranged to prevent the gas from escaping between the outer housing 1 and the inner housing 4 during inflation and deflation.

[0031] Both ends of the inner housing 4 are provided with plug-in ports 10 electrically connected with the inflation and deflation motor 5.

[0032] In the embodiment, the mobile power supply is connected with the plug-in port 10 to provide power for the inflation and deflation motor 5.
