[0019] The following is in conjunction with the appendix Figure 1-4 The present invention will be further described as follows:

[0020] A combined bidirectional air pump includes an outer casing 1. An inner casing 2 is detachably mounted on one side of the outer casing 1 via a connecting device 11. An intake motor 6 and a power supply device 10 are fixedly mounted inside the inner casing 2. An air intake passage 4 and an air intake passage 17, respectively cooperating with the intake motor 6, are provided on the top and side of the inner casing 2. An air intake hole 18, cooperating with the air intake passage 17, is opened on the side of the outer casing 1. An inner casing 20 is fixedly mounted on the other side of the outer casing 1. An exhaust motor 5 is fixedly mounted inside the inner casing 20. The top of body 20 is provided with an exhaust duct 3, and an exhaust sealing cover 19 is detachably installed on the exhaust duct 3. The bottom of the outer shell 1 is provided with an exhaust hole 9 that cooperates with the exhaust motor 5. The top of the inner shell 1 and the inner shell 20 are respectively provided with an intake switch 8 and an exhaust switch 7 that are electrically connected to the intake motor 6 and the exhaust motor 5. Both the intake switch 8 and the exhaust switch 7 are electrically connected to the power supply device 10. The top of the outer shell 1 is provided with a sealing cover 12, and the exhaust motor 5, the intake motor 6 and the power supply device 10 are all located inside the sealing cover 12.

[0021] In this embodiment, the outer shell 1 is fixedly connected to the inflatable product, and the inner shell 2 is detachably disposed inside the outer shell 1.

[0022] When the inner shell 2 is installed inside the outer shell 1, both the exhaust motor 5 and the intake motor 6 are electrically connected to the power supply device 10, which provides power to the exhaust motor 5 and the intake motor 6. Pressing the intake switch 6 or the exhaust switch 7 will power on the exhaust motor 5 and the intake motor 6, enabling the deflation or inflation of the inflatable product.

[0023] One side of the sealing cover 12 is rotatably connected to the outer shell 1 via a rotating shaft 13. A sealing block 14 is fixedly provided on the other side of the sealing cover 12. A sealing groove 15 that cooperates with the sealing block 14 is provided on the outer shell 1. A sealing gasket 16 is provided at the joint between the outer shell 1 and the sealing cover 12.

[0024] In this embodiment, the sealing cover 12 is closed by the cooperating sealing block 14 and sealing groove 15. The sealing cover 12 is sealed by the sealing gasket 16, which prevents gas leakage and waterproofing.

[0025] Open the sealing cover 12, press the air intake switch 8, and the air intake motor 6 will start. Outside air enters the air intake motor 6 through the air intake duct 4, and then enters the inflatable product through the air intake duct 17 and the air intake hole 18, thus inflating the inflatable product. Preferably, a one-way valve is provided in the air intake duct 17 to prevent the air inside the inflatable product from flowing backward and being discharged from the air intake motor 6.

[0026] Open the vent sealing cover 19, press the vent switch 7, start the vent motor 5, and the air inside the inflatable product enters the vent motor 5 through the vent hole 9, and then vents the inflatable product through the vent passage 3.

[0027] When the inner shell 2 is removed from the outer shell 1, the exhaust motor 5 is disconnected from the power supply 10. The intake motor 6 inside the inner shell 2 and the power supply 10 form an independent, movable, bidirectional air pump. When the inflatable product is connected to the air inlet channel 17 via the air nozzle, pressing the air inlet switch 8 starts the air inlet motor 6. Outside air enters the air inlet motor 6 through the air inlet channel 4, and then enters the inflatable product through the air inlet channel 17, thus inflating the product. When the inflatable product is connected to the air inlet channel 4 via the air nozzle, pressing the air inlet switch 8 starts the air inlet motor 6. Air inside the inflatable product enters the air inlet motor 6 through the air inlet channel 4, and then exits through the air inlet channel 17, thus deflating the product.

[0028] The connecting device 11 includes an inner shell locking block 111 and springs 113. The inner shell locking blocks 111 are fixedly installed on both sides of the top of the inner shell 2. The top of the outer shell 1 is provided with an inner shell locking groove 112 that cooperates with the inner shell locking block 111. The bottom of the outer shell 1 is fixedly provided with a plurality of springs 113 that contact and cooperate with the bottom of the inner shell 2.

[0029] The power supply device 10 includes a rechargeable battery 101 fixedly installed inside the inner housing 1 2. The rechargeable battery 101 is electrically connected to the intake switch 8. Electrodes 1 102 and 2 103 are respectively fixedly installed on the outside of the inner housing 1 2 and the inner housing 2 20 on the side that are close to each other. Electrode 1 102 is electrically connected to the rechargeable battery 101, and electrode 2 103 is electrically connected to the exhaust switch 7.

[0030] In this embodiment, the inner shell 2 is inserted into the outer shell 1. The inner shell locking block 111 and the inner shell locking groove 112 cooperate to lock the inner shell 2 into the outer shell 1. At this time, the electrode 102 and the electrode 2 103 are in contact, the rechargeable battery 101 and the exhaust switch 7 are electrically connected, and the spring 85 is in a compressed state.

[0031] Simultaneously, the two inner shell locking blocks 111 are pressed inward, separating the inner shell locking blocks 111 from the inner shell locking slots 112. The spring 103 extends, pushing the inner shell 2 upward, and the electrodes 102 and 103 are no longer in contact. The rechargeable battery 101 and the exhaust switch 7 are in a de-energized state. The user can remove the inner shell 2 by holding the upper end, forming an independent, portable, bidirectional air pump.

[0032] The top of the inner casing 2 is provided with a charging port 104 that is electrically connected to the rechargeable battery 101. Preferably, the rechargeable battery 101 can be charged through the charging port 104 using a charger or power bank.
