[0051] like Figures 1-3 As shown, based on the above embodiment, a protective space is formed between each of the winding seats 120, and the core seat 110 is disposed in the protective space.

[0052] In this embodiment, the core seat 110 is disposed within the protective space formed between the winding seats 120. Therefore, the winding seats 120 can not only house the air tube 200, but also protect the core seat 110 located within the protective space.

[0053] like Figures 1-3 As shown, based on the above embodiment, one end of the winding seat 120 is connected to the pump body 100, and the other end of the winding seat 120 is provided with a limiting block 121 that is away from the winding space. A limiting space is formed between the limiting block 121 and the pump body 100, and the air tube 200 is located in the limiting space when it is wound around the winding seat 120.

[0054] In this embodiment, the two ends of the winding seat 120 are connected to the pump body 100 and the limiting block 121, respectively. When the air tube 200 is wound around the winding seat 120, it is located in the limiting space formed between the limiting block 121 and the pump body 100, which prevents the air tube 200 from slipping off the winding seat 120.

[0055] like Figures 1-3 As shown, based on the above embodiment, the pump body 100 is further provided with a positioning seat 113, which is located in the installation space.

[0056] In this embodiment, the connecting part 320 is manually pushed in to push open the mounting block 111 and snap into the mounting space. The positioning seat 113 can contact the connecting part 320 to position the connecting part 320, thereby restricting the movement of the air core 300.

[0057] like Figures 1-3As shown, on the basis of the above embodiment, the pump body 100 is further provided with a detachable function plate 130, and the core seat 110, the positioning seat 113 and the winding seat 120 are arranged on the function plate 130 and detachably connected with the pump body 100 through the function plate 130.

[0058] In the embodiment, the core seat 110, the positioning seat 113 and the winding seat 120 are detachably connected with the pump body 100 through the function plate 130, so that each functional unit is modularly arranged on the function plate 130 and is installed when needed and is detached when not needed.

[0059] In addition, it is worth mentioning that the number of the winding seat 120 can be two, and the two winding seats 120 are respectively located at the two ends of the function plate 130, thereby playing a role similar to a handle.

[0060] Specifically, the pump body 100 is further provided with a clamping groove 140, and the function plate 130 is provided with a buckle 131 which can be clamped with the clamping groove 140.

[0061] As shown in the drawings, Figures 1-3 As shown, on the basis of the above embodiment, the function plate 130 is provided with a fixing seat 132, and the fixing seat 132 is provided with a fixing groove 133.

[0062] In the embodiment, the function plate 130 is provided with the fixing seat 132, and the trachea 200 or the air core 300 can be temporarily clamped through the fixing seat 132, thereby facilitating the use of the air pump with replaceable air core 300.

[0063] As shown in the drawings, Figures 1-3 As shown, on the basis of the above embodiment, the function plate 130 is provided with an air core cover seat 134 for fixing the air core cover.

[0064] In the embodiment, in the existing scene, the user needs to unscrew the air core cover when inflating, but there is no place to place it, so it is easy to lose. Therefore, the air core cover seat 134 for fixing the air core cover is arranged on the function plate 130, and the unscrewed air core cover can be directly screwed into the air core cover seat 134, thereby preventing the air core cover from being lost.
