[0028] In another specific embodiment, the pump housing 1 includes a front cover body 11 and a rear cover body 12. The front cover body 11 and the rear cover body 12 are detachably connected and surround each other to form an installation cavity for accommodating the pump housing 1, the battery component 2 and the dual-purpose air pump core assembly 3.

The ring-shaped indicator light 53 and the circuit board 51 are located in the center of the front cover 11, physically close to the battery unit 2, facilitating electrical connection. The lighting function of the ring-shaped indicator light 53 facilitates user use at night or outdoors. The dual-purpose air pump core assembly performs both inflation and deflating functions, with both the inflation and deflating ports located on the same side for easy switching between the two functions. Furthermore, a ring-shaped indicator light is arranged around the display screen on the front side of the housing, providing an appropriate ambient lighting area during nighttime operation, facilitating both inflation and deflating operations and making it convenient for users to operate the pump at night or outdoors.

[0029] In a specific embodiment, Figure 4 As shown, the dual-purpose air pump core assembly 3 also includes an air extraction assembly 32 and an air filling assembly 31. The air extraction assembly 32 is connected to the air filling assembly 31 through a one-way valve structure 33. The inflation interface 3151 and the air extraction interface 3241 of the dual-purpose air pump are both arranged on the same side, which is more convenient for users to perform conversion functions.

[0030] In a specific embodiment, the air extraction component may include a first pump and an air extraction structure, wherein the inflation component includes a second pump and an inflation structure, and the air extraction structure is connected to the inflation structure through a one-way valve structure. The air extraction structure and the first pump are longitudinally arranged in sequence below the air extraction interface, and the side wall of the air extraction structure is connected to the side wall of the inflation structure through a one-way valve structure. The inflation structure is arranged below the inflation interface, the second pump is transversely arranged below the first pump and the output shaft is connected to the inflation structure, and the battery is installed at the bottom of the pump housing below the second pump. In this embodiment, the one-way valve is opened when the air extraction component is extracting air so that the interior of the air extraction component is connected to the interior of the inflation component, and is closed when the inflation component is inflated so that the interior of the air extraction component is not connected to the interior of the inflation component. In this embodiment, the air extraction structure may include an impeller and a first pump housing. The first pump housing is provided with an air extraction chamber for accommodating the impeller. The upper end of the first pump housing is connected to the air extraction interface. The first pump drive shaft is connected to the impeller and can drive the impeller to rotate in the first pump housing to extract gas through the air extraction interface. In another specific embodiment, Figure 5 As shown, the first pump housing 323 and the first pump 321 are arranged longitudinally in sequence below the air extraction interface 3241. The sidewall of the first pump housing 323 is connected to the sidewall of the second pump housing 311 via a one-way valve structure 33. The second pump housing 311 is arranged below the air charging interface 3151. The second pump 312 is arranged transversely below the first pump 321, and its output shaft passes through the second pump housing 311 and is connected to the internal transmission mechanism 313. The battery unit 2 is mounted on the pump housing bottom plate below the second pump 312. The first pump housing 323, the first pump 321, and the second pump 312 are arranged longitudinally in sequence, resulting in a compact structure.

[0031] In a specific embodiment, the one-way valve 33 opens when the vacuum component 32 is vacuuming, so that the interior of the vacuum component 32 is connected to the interior of the inflation component 31, and closes when the inflation component 31 is inflated, so that the interior of the vacuum component 32 is not connected to the interior of the inflation component 31, thereby preventing the compressed air from flowing in reverse.

[0032] In a specific embodiment, the vacuum assembly 32 includes a first pump 321, an impeller 322, and a first pump housing 323. The first pump housing 323 is provided with a vacuum chamber for accommodating the impeller 322. The upper end of the first pump housing 323 is connected to the vacuum structure 324. The driving shaft of the first pump 321 is connected to the impeller 322 and can drive the impeller 322 to rotate in the first pump housing 323 to extract gas through the vacuum structure 324. The impeller 322 sucks air from the vacuum interface and passes through the one-way valve structure 33 to be transported to the inflation interface to discharge the inflation pump. The existence of the one-way valve structure 33 prevents air from flowing from one side of the inflation assembly 31 to the side of the vacuum assembly 32.

[0033] The inflation assembly 31 includes a second pump housing 311, a second pump 312, and a transmission mechanism 313 and piston rod 314 disposed within the second pump housing 311. The second pump housing 311 also includes a cylinder chamber 3111, and the upper end of the second pump housing 311 communicates with the inflation structure 315. The first pump 321, first pump housing 323, second pump housing 311, and second pump 312 are all constructed of metal, ensuring the pump can withstand a certain pressure regardless of whether it is inflating or deflating, demonstrating its high pressure resistance.

[0034] The output shaft of the second pump 312 is provided with a drive gear 3121. The transmission mechanism 313 includes a driven gear 3131 meshing with the drive gear and an eccentric shaft 3132 eccentrically mounted on the driven gear. The rear end of the piston rod 314 is provided with a mounting ring 3141, which is sleeved onto the eccentric shaft 3132 and can rotate about the eccentric shaft 3132. The drive gear 3121 is coaxially fixedly connected to the transmission shaft of the second pump 312, and the drive gear 3121 and the driven gear 3131 are arranged axially parallel. When the drive gear 3121 drives the driven gear 3131 to rotate, the eccentric shaft 3132 can drive the mounting ring 3141 to follow the driven gear 3131 in a circular motion, thereby driving the piston member at the top of the piston rod 314 to reciprocate within the cylinder body 3111, thereby delivering gas to the inflatable structure 315. The driving gear 3121 and the driven gear 3131 together form a pair of meshing gears. In this embodiment, they can be set as a cylindrical spur gear mechanism for transmitting motion between parallel axes. Compared with mechanical transmissions such as friction wheels and pulleys, the gear transmission has a stable transmission ratio, reliable operation and a long service life.

[0035] In a specific embodiment, the display screen module 52 includes a light-transmitting panel 521 and a display element 522. The front portion of the front cover 11 is provided with a mounting channel connecting the mounting cavity and the outside of the pump housing. The display element 522 is installed in the mounting channel and fixedly connected to the circuit board 51 located at the rear of the mounting channel. Figure 6 As shown, the light-transmitting panel 521 is fixed to the front periphery of the installation channel via a connecting portion 5211 and covers the passage opening of the installation channel. The light-transmitting panel 521 is located at the outermost portion of the front cover 11, and the display element 522 and the circuit board 51 are arranged in sequence. In this embodiment, the display element 522 and the circuit board 51 are connected by screws. In specific embodiments, the material of the light-transmitting panel 521 can be transparent plastic or glass, etc., and the specific use is selected according to the application scenario of the air pump.

[0036] In this embodiment, a ring-shaped indicator light 53 is arranged around the light-transmitting panel 521 on the front portion of the front cover 11. Placed directly in front of the main body, the ring-shaped indicator light 53 provides high brightness, concentrated light, and shadow-free illumination, providing uniform, seamless illumination. Furthermore, in another embodiment, the ring-shaped indicator light 53 can also serve as a reminder, displaying different colors or flashing in various rhythms to convey specific information to the user when the dual-purpose air pump is in various states, such as inflation, deflating, and malfunctioning.

[0037] In a specific embodiment, the annular indicator light 53 includes a circular light bar 531 and a circular lampshade 532 matching the circular light bar 531. Figure 7 As shown, the annular lampshade 532 includes an annular light-transmitting plate 5321 and two sidewalls 5322 arranged on both edges of the annular light-transmitting plate 5321 and bent toward the pump housing. The two sidewalls 5322 and the annular light-transmitting plate 5321 surround and form a mounting groove for accommodating the annular indicator light 53. The annular lampshade 532 protects the annular light bar 531, softening the light and protecting the eyes from excessive light stimulation. It also protects the lamp body from minor external impacts, thereby extending the service life of the annular light bar.

[0038] In a specific embodiment, the front portion of the front cover 11 is provided with multiple slots. The edges of the two side walls 5322 of the annular lampshade 532 are provided with multiple clips 5323 that can be detachably connected to the corresponding slots. The annular light bar 531 has corresponding slots at the locations of the clips 5323 on the two side walls 5322 of the annular lampshade 532. This secures the relative position of the annular light bar 531 and the annular lampshade 532, preventing the annular light bar 531 from sliding. The multiple clips 5323 on either side of the two side walls 5322 distribute the force, reduce the risk of clip breakage, and extend the service life of the components. This slot-and-clip connection facilitates the installation and removal of components.

[0039] In a specific embodiment, the front portion of the front cover 11 is provided with an inwardly recessed recess 113. The bottom of the recess 113 is provided with a mounting channel. The edge of the bottom plate of the recess 113 is provided with multiple notches. These notches and the side walls of the recess 113 surround each other to form a slot for connecting with the clip 5323 on the outer wall of the annular lampshade 532. The use of the slot and clip connection method facilitates the assembly and disassembly of parts. The outer wall of the annular lampshade 532 abuts against the side wall of the recess 113, reducing the gap between the two walls and helping to reduce the shaking of the parts when the air pump is operating.
