[0044] The shell 1 comprises an outer shell 2 and an inner shell 3. A gap is formed between the outer shell 2 and the inner shell 3 for exchanging air with the outside. When the air charging process is in progress, the outside air enters the second air outlet 6 through the gap. When the air discharging process is in progress, the air inside the air charging product (such as an air bed) is discharged to the outside through the gap. The inner shell 3 is provided with an air inlet 4 for inhaling the outside air or discharging the air inside the air charging product. The inner shell 3 is further provided with a first air outlet 5 for outputting or inhaling air. The outer shell 2 is provided with a second air outlet 6 at the position of the first air outlet 5, which is used for connecting the external air charging product (such as an air bed).

[0045] The air pump module 7 comprises a motor 8, an air chamber casing 9 and an impeller 10. The motor 8 is arranged in the inner shell 3 to provide power. The air chamber casing 9 is installed on the motor 8 and is internally provided with a channel for air flow. The impeller 10 is connected with the rotating end of the motor 8. When the motor 8 is started, the impeller 10 rotates to generate air flow. Preferably, the air chamber casing 9 has a first air port 11 and a second air port 12. The first air port 11 is arranged above the second air port 12. The first air port 11 is preset as an air outlet, and the second air port 12 is preset as an air inlet. When the motor 8 rotates to drive the impeller 10 to rotate, if the air charging state is in progress, at this time, the first air port 11 is in communication with the first air outlet 5 and the second air outlet 6. The outside air enters through the second air port 12 and is discharged to the first air port 11 through the impeller 10, so as to charge the air charging product.

[0051] When the air suction is needed, the air suction key 28 is pressed, the air suction connecting rod 31 drives the transverse connecting rod 32 to move the trigger switch 33, at the same time, the switch assembly 13 is driven, the second air outlet 12 is communicated with the third air outlet 16, the first air outlet 5 and the second air outlet 6. At the same time, the switch frame 15 drives the connecting rod 21 to move, and pushes the air sealing piece 20 to open the second air outlet 6. The gas from the external equipment enters the air chamber shell 9 through the second air outlet 6, the first air outlet 5, the third air outlet 16 and the second air outlet 12, and then is discharged through the first air outlet 11. The gas is discharged through the gap between the inner shell 3 and the outer shell 2.

[0052] As shown in Figures 15-16 The transverse connecting rod 32 is provided with a first guide bevel 36 at the position of the reset connecting rod 30, a dialing part 37 at the position of the switch 33, a first guide convex point 38 at the position of the air charging connecting rod 29, and a second guide convex point 39 at the position of the air suction connecting rod 31.

[0053] The above provides an implementable linkage structure, the movement process of which is as follows: When inflating, the inflation button 26 is pressed, the second guide bevel 41 on the inflation linkage 29 cooperates with the first guide protrusion 38, moving the transverse linkage 32, the toggle part 37 triggers the switch 33, the motor 8 works, and the first guide protrusion 38 is placed on the first limit protrusion 42. After inflation is completed, the reset button 27 is pressed, the third guide protrusion 40 on the reset linkage 30 cooperates with the first guide bevel 36, moving the transverse linkage 32, releasing the first limit protrusion 42 from the first guide protrusion 38, and the inflation linkage 29 is reset under the action of the spring 35. After releasing the reset button 27, the transverse linkage 32 is reset under the action of the reset spring 34, and the toggle part 37 leaves the switch 33. When air is being pumped out, the pumping button 28 is pressed, and the third guide bevel 43 on the pumping linkage 31 engages with the second guide protrusion 39 to move the transverse linkage 32.

When the reset button 27 is pressed by external force, the pusher 45 drives the connecting rod 21 to move and open the sealing plate 20 to extract air. Specifically, the pusher 45 is inclined. When the switching frame 15 moves longitudinally in the air extraction state, the pusher 45 in the third air outlet 16 pushes the connecting rod 21 to open the sealing plate 20, facilitating the extraction of gas from inside the inflatable product.

[0056] Specifically, the air chamber housing 9 includes an upper cover 46, a middle cover 47, and a lower cover 48. The impeller 10 is installed between the middle cover 47 and the upper cover 46.

[0061] Embodiment 2: Air cushion bed

[0062] The air cushion bed comprises the built-in air pump and the air cushion body of the air cushion bed of the above embodiment 1. The air cushion body has an air chamber for accommodating air and providing supporting force. The built-in air pump is connected with the air chamber of the air cushion body through a pipeline, and is used for providing air charging or air exhausting function for the air cushion body.

[0063] In use, the air cushion bed is unfolded and laid flat. Then the air charging button 26 of the built-in air pump is pressed to charge air until the air cushion body reaches the required hardness and height. When air exhausting is needed, the air exhausting button 28 is pressed to exhaust air until the air cushion body is completely laid flat and folded for storage.

[0064] In summary, the built-in air pump and the air cushion bed have the advantages of simple structure, convenient operation, flexible function, and are suitable for various occasions requiring air charging or air exhausting.

[0065] The above is not intended to limit the technical scope of the present application, and any modifications, equivalent changes and modifications made to the above embodiments in accordance with the technical essence of the present application are still within the scope of the technical solution of the present application.
