[0043] It should be noted that, unless otherwise specified, the embodiments and features described in this application can be combined with each other. The preferred embodiments of this utility model will now be described in detail with reference to the accompanying drawings.

[0044] This utility model embodiment provides an air pump 1000, such as Figures 2-6As shown, the air pump 1000 includes a housing 100 and a pump body 200. The housing 100 includes a first side 110, a second side 120, and a third side 130. The first side 110 and the second side 120 are arranged opposite to each other, and the third side 130 is adjacent to the first side 110 and the second side 120. The first side 110 has an opening 111 and a first air inlet structure 112. The second side 120 has an air outlet structure 121, the area of ​​which is larger than the area of ​​the first air inlet structure 112. The third side 130 has a second air inlet structure 131. The pump body 200 is installed inside the housing 100. One side of the pump body 200 has an air outlet 210, and the other side has a fan 220. The air outlet 210 is located at the opening 111. The first air inlet structure 112 and the air outlet structure 121 are located axially on the fan 220, and the second air inlet structure 131 is located radially on the fan 220.

[0045] Specifically, the third side 130 of the air pump 1000 provided in this embodiment is provided with a second air intake structure 131. The second air intake structure 131 is located in the radial direction of the fan 220. The second air intake structure 131 can increase the air intake of the outer shell 100, thereby increasing the air permeability of the outer shell 100 and improving the heat dissipation effect of the air pump 1000.

[0046] refer to Figures 2-6 In some embodiments, the first air intake structure 112 includes a plurality of first air intake holes 1121, the second air intake structure 131 includes a plurality of second air intake holes 1311, and the air outlet structure 121 includes a plurality of air outlet holes 1211. The sum of the areas of the plurality of air outlet holes 1211 is greater than the sum of the areas of the plurality of first air intake holes 1121, so the area of ​​the air outlet structure 121 is greater than the area of ​​the first air intake structure 112.

[0047] refer to Figure 2 and Figure 3 In some embodiments, the air pump 1000 further includes a first cover plate 310, which covers the opening 111 and the first air intake structure 112 on the side away from the fan 220. The first cover plate 310 is movably connected to the housing 100 so that the first cover plate 310 can be moved to expose the opening 111 and the first air intake structure 112.

[0048] By implementing this embodiment, when the pump body 200 is not needed, the opening 111 and the first air intake structure 112 can be covered by the first cover plate 310 to prevent external dust from entering the air outlet 210 and the housing 100.

[0049] It should be noted that there are many specific implementations of the first cover plate 310 being movably connected to the outer shell 100. This embodiment is not limited here, as long as the opening 111 and the first air intake structure 112 can be covered or exposed by the movable first cover plate 310. Several specific embodiments are listed below for illustration.

[0050] refer to Figures 2-8 In Embodiment 1, a flexible connecting block 311 is provided on the side of the first cover plate 310 facing the opening 111, and an insertion hole 113 is provided on the outer shell 100 for inserting the flexible connecting block 311. The flexible connecting block 311 cooperates with the insertion hole 113 so that the first cover plate 310 and the outer shell 100 are movably connected.

[0051] Specifically, when the first cover plate 310 is covering the opening 111 and the first air intake structure 112, simply lifting the first cover plate 310 will expose the opening 111 and the first air intake structure 112. Since the flexible connecting block 311 is flexible, it can deform when the first cover plate 310 moves, so it will not affect the opening of the first cover plate 310. After use, simply replacing the first cover plate 310 will cover the opening 111 and the first air intake structure 112.

[0052] In Embodiment 2, the first cover plate 310 is rotatably connected to the outer casing 100, so that the first cover plate 310 can be moved to expose the opening 111 and the first air intake structure 112. With this configuration, when the first cover plate 310 is covering the opening 111 and the first air intake structure 112, simply rotating the first cover plate 310 will open the first cover plate 310 to expose the opening 111 and the first air intake structure 112. After use, simply rotating the first cover plate 310 in the opposite direction will cover the opening 111 and the first air intake structure 112.

[0053] Furthermore, the air pump 1000 also includes a rotating shaft (not shown in the figure), and the first cover plate 310 is rotatably connected to the housing 100 via the rotating shaft.

[0054] In Embodiment 3, the first cover plate 310 is detachably connected to the outer casing 100 so that the first cover plate 310 can be moved to expose the opening 111 and the first air intake structure 112. With this configuration, when the first cover plate 310 is covering the opening 111 and the first air intake structure 112, the opening 111 and the first air intake structure 112 can be exposed simply by removing the first cover plate 310. After use, the opening 111 and the first air intake structure 112 can be covered by simply installing the first cover plate 310.

[0055] Furthermore, the detachable connection methods include, but are not limited to, magnetic attraction, snap-fit ​​connection, interference fit, etc., which are not limited in this embodiment.

[0056] In Embodiment 4, the first cover plate 310 is slidably connected to the outer casing 100, so that the first cover plate 310 can be moved to expose the opening 111 and the first air intake structure 112. With this configuration, when the first cover plate 310 is covering the opening 111 and the first air intake structure 112, simply sliding the first cover plate 310 will expose the opening 111 and the first air intake structure 112. After use, simply sliding the first cover plate 310 in the opposite direction will cover the opening 111 and the first air intake structure 112.

[0057] Furthermore, the outer casing 100 is provided with a slide rail (not shown in the figure), and the first cover plate 310 is provided with a slide groove (not shown in the figure) adapted to the slide rail. The slide rail and the slide groove cooperate to make the first cover plate 310 slidably connected to the outer casing 100.

[0058] refer to Figure 4 and Figure 8 In some embodiments, the socket 113 is a through hole, and the flexible connecting block 311 passes through the through hole. The flexible connecting block 311 includes a connecting section 3111 located on the side of the through hole near the fan 220. The outer contour of the connecting section 3111 is larger than the contour of the through hole.

[0059] By implementing this embodiment, since the outer contour of the connecting segment 3111 is larger than the outer contour of the through hole, the flexible connecting block 311 will not be dislodged from the through hole due to external force, thus ensuring the connection stability between the first cover plate 310 and the outer shell 100.

[0060] Specifically, since the flexible connecting block 311 is flexible, when installing the flexible connecting block 311, the connecting segment 3111 can be forcefully inserted from the side of the through hole away from the fan 220 into the side of the through hole close to the fan 220, thereby achieving the connection between the first cover plate 310 and the outer casing 100.

[0061] refer to Figure 8 Furthermore, in order to facilitate the insertion of the connecting segment 3111 into the through hole near the fan 220, thereby achieving the connection between the first cover plate 310 and the outer casing 100, in a specific embodiment, the outer contour of the connecting segment 3111 has a narrowing trend in the direction near the fan 220. This can play a guiding role when the connecting segment 3111 is inserted into the through hole, making it easier for the connecting segment to pass through the through hole.

[0062] refer to Figure 8 In some embodiments, the first cover plate 310 is further provided with a plug-in block 312 on the side facing the opening 111. The plug-in block 312 is used to plug into the first air intake structure 112 and / or the air outlet 210.

[0063] Specifically, by engaging the plug block 312 with the first air intake structure 112 and / or the air outlet 210, the stability of the first cover plate 310 covering the opening 111 and the first air intake structure 112 can be increased, preventing the first cover plate 310 from being opened by external forces, thus improving the user experience.

[0064] refer to Figures 2-7 In some embodiments, a receiving groove 114 is provided on the side of the first side 110 facing away from the second side 120, and a first cover plate 310 is provided on the receiving groove 114.

[0065] Specifically, if the first cover plate 310 protrudes entirely from the first side surface 110, the side of the first cover plate 310 will be exposed, and external force applied to the side of the first cover plate 310 can easily cause the first cover plate 310 to be lifted. To solve this technical problem, this embodiment provides a receiving groove 114 for accommodating the first cover plate 310 on the side of the first side surface 110 facing away from the second side surface 120. The receiving groove 114 allows the first cover plate 310 to be recessed, so that the side of the first cover plate 310 is hidden, reducing the probability that the first cover plate 310 will be lifted by external force.

[0066] refer to Figure 8 In a specific embodiment, the first cover plate 310 is provided with a pull block 313 on the side facing away from the fan 220, and the pull block 313 protrudes from the receiving groove 114.

[0067] Specifically, since the receiving groove 114 hides the side of the first cover plate 310, it is difficult for the user to find a suitable point of force when trying to lift the first cover plate 310. Without a structure that facilitates the user to apply pulling force to the first cover plate 310, it would be difficult for the user to lift the first cover plate 310, resulting in a poor user experience. Based on this, this embodiment provides a pull block 313 on the side of the first cover plate 310 facing away from the fan 220. The pull block 313 protrudes from the receiving groove 114 to facilitate the user to lift the first cover plate 310 using the pull block 313.

[0068] refer to Figure 6 and Figure 7 In some embodiments, the air pump 1000 further includes a main control module 400, a battery 500, and a discharge interface 600. The main control module 400 is electrically connected to the air pump 1000, the battery 500 is electrically connected to the main control module 400, and the discharge interface 600 is electrically connected to the main control module 400 and exposed in the housing 100. The discharge interface 600 is used to connect an external battery clamp 9000.

[0069] This embodiment demonstrates a multi-functional air pump 1000, which can not only inflate tires but also connect to battery clamps 9000 to jump-start batteries. For users who would otherwise need to purchase multiple automotive accessories with different functions, this not only saves on purchase costs but also saves on storage space, resulting in a better user experience.

[0070] Furthermore, the discharge interface 600 is a bidirectional interface, enabling the user to charge the battery 500 using the discharge interface 600.

[0071] refer to Figure 2 In a specific embodiment, the air pump 1000 also includes a lighting lamp 700, which is electrically connected to the main control module 400 and exposed in the housing 100.

[0072] This embodiment demonstrates a multi-functional air pump 1000, which can not only inflate tires, but also jump-start batteries by connecting external battery clamps 9000, and provide lighting. For users who would otherwise need to purchase multiple automotive accessories with different functions at the same time, this not only saves on purchase costs, but also saves on storage space, resulting in a better user experience.

[0073] refer to Figure 8 In some embodiments, the air pump 1000 also includes a USB interface 800, which is electrically connected to the main control module 400 and exposed in the housing 100.

[0074] This embodiment demonstrates a multifunctional air pump 1000, which can not only inflate tires, but also jump-start batteries by connecting external battery clamps 9000, and provide power to mobile phones, tablets, fans 220 and other electrical devices via USB interface 800, providing a good user experience.

[0075] refer to Figure 10 In a specific embodiment, there are two USB interfaces 800, and the two USB interfaces 800 are of different types, so that the air pump 1000 can be adapted to different types of data cables, making it more versatile.

[0076] refer to Figure 2 In some embodiments, the main control module 400 is provided with multiple buttons 410, which are used to control the lighting lamp 700 and the air pump respectively. For example, one button 410 is used to turn the brightness of the lighting lamp 700 on and off, one button 410 is used to control the pump body 200 on and off, one button 410 is used to increase the air output of the pump body 200, and one button 410 is used to decrease the air output of the air pump.

[0077] refer to Figure 2In some embodiments, the air pump 1000 further includes a second cover plate 320, which covers the discharge interface 600 and is movably connected to the housing 100 so that the second cover plate 320 can be moved to expose the discharge interface 600.

[0078] By implementing this embodiment, when the discharge interface 600 is not needed, the second cover plate 320 can be used to cover the discharge interface 600 to prevent external dust from entering the discharge interface 600.

[0079] The movable connection method between the second cover plate 320 and the outer shell 100 can refer to the movable connection method between the first cover plate 310 and the outer shell 100 described above, and will not be repeated here in this embodiment.
