[0026] Please see Figure 1-5 This utility model provides a technical solution: a built-in lithium battery air pump, including a shell 1, an air inlet 2 at the bottom of the shell 1, a supporting component 3 at the bottom of the inner cavity of the shell 1, a cover 4 at the top of the supporting component 3, a groove 5 at the center of the top of the cover 4, an air inlet tube 6 at the center of the bottom of the groove 5, and an air guide nozzle 8 at the center of the top of the inner cavity of the cover 4; a micro air pump 9 is provided in the inner cavity of the supporting component 3, an electronic control board 10 and a lithium battery 11 are provided on the side wall of the inner cavity of the supporting component 3, a control switch 12 is provided on one side of the top surface of the cover 4, a shielding cap 14 is rotatably connected to the top of the shell 1, and a protective ring 15 is provided on the outer side of the shell 1;

[0027] The outer casing 1 serves to both install, fix, and protect the supporting component 3, as well as allow for the rotational installation of the shielding cap 14 and the installation and fixation of the protective ring 15. The supporting component 3 also provides installation and protection for the cover 4, the micro air pump 9, the electronic control board 10, and the lithium battery 11. Furthermore, the supporting component 3, in conjunction with the cover 4, forms a protective space. Combined with the outer casing 1 and the shielding cap 14, this provides dual protection for the micro air pump 9, the electronic control board 10, and the lithium battery 11, thereby extending their lifespan. When inflating equipment such as air mattresses, inflatable bathtubs, and inflatable swimming pools, first connect the air inlet of the external device to the inflation tube 6. Then, through the control switch 12, the micro air pump 9 can be turned on via the electronic control board 10. The micro air pump 9 can draw in outside air through the air inlet 2, pressurize it, and then deliver it to the inflation tube 6 through the air guide nozzle 8, thereby inflating the external device connected to the inflation tube 6. The lithium battery 11 can power the device, thus ensuring the device's battery life. Since the outer shell 1 is provided with a protective ring 15, the protective effect of the outer shell 1 can be further enhanced, and the service life of the air pump can be improved.

[0028] See Figures 3-5 The bottom end of the air guide nozzle 8 is connected to the air outlet of the micro air pump 9, and the top end of the air guide nozzle 8 is connected to the bottom end of the inflation tube 6, which allows the micro air pump 9 to conveniently deliver pressurized gas to the inflation tube 6 through the air guide nozzle 8.

[0029] See Figures 3-6 The supporting component 3 includes an inner shell 31 disposed in the inner cavity of the outer shell 1. A support ring 32 is integrally formed on the bottom surface of the inner shell 31, and an air guide hole 33 is opened at the center of the bottom surface of the inner shell 31. A positioning ring 34 for installing a micro air pump 9 is disposed in the inner cavity of the inner shell 31. A positioning plate 35 is disposed on the outer side of the positioning ring 34. One end of the positioning plate 35 is fixedly connected to the inner wall of the inner shell 31. An isolation plate 36 for installing an electronic control board 10 and a lithium battery 11 is disposed on one side of the inner wall of the inner shell 31. A filter screen plate 37 is disposed on the bottom surface of the inner shell 31 and in the inner cavity of the support ring 32. A claw 38 for engaging the filter screen plate 37 is provided around the inner cavity of the support ring 32.

[0030] By supporting the inner shell 31 in component 3, it can be stably placed in the inner cavity of outer shell 1 via support ring 32, and space can be provided for the air guide hole 33. Then, the micro air pump 9 can be installed and fixed by positioning ring 34 and positioning plate 35, thereby improving the stability of micro air pump 9 in use. The electronic control board 10 and lithium battery 11 can be installed and fixed by isolation plate 36. Then, the filter screen plate 37 can be engaged and limited by two claws 38 on support ring 32, so that the filter screen plate 37 can filter the gas entering the air guide hole 33, thereby preventing external dirt from clogging micro air pump 9.

[0031] See Figures 3-5 The bottom surface of the inner cavity of the groove 5 and both sides of the inflation tube 6 are provided with locking holes 7, and the two sides of the air guide nozzle 8 are respectively inserted into the inner cavity of the two locking holes 7.

[0032] The air nozzle 8 can be engaged and limited through the locking hole 7, thereby improving the stability of the air nozzle 8 in use.

[0033] See Figure 4 , Figure 5 A charging port 13 is provided on the other side of the top surface of the cover 4, and the charging port 13 is electrically connected to the electronic control board 10, which can be conveniently connected to an external power source, so that the lithium battery 11 can be charged through the electronic control board 10.

[0034] See Figure 4 , Figure 5 The top surface of the cover 4 has multiple heat dissipation holes 16, which are arranged in a ring array to dissipate the heat accumulated in the cover 4 and the inner shell 31, thereby improving the safety of the micro air pump 9.

[0035] During operation, the outer casing 1 serves to both install, fix, and protect the lifting assembly 3, as well as rotate and install the shielding cap 14 and fix the protective ring 15. The lifting assembly 3 then serves to install and protect the cover 4, micro air pump 9, electronic control board 10, and lithium battery 11. Furthermore, the lifting assembly 3, together with the cover 4, forms a protective space. Combined with the outer casing 1 and shielding cap 14, this provides double protection for the micro air pump 9, electronic control board 10, and lithium battery 11, thereby extending their lifespan. To inflate equipment such as air mattresses, inflatable bathtubs, and inflatable swimming pools, first connect the air inlet of the external device to the inflation tube 6. Then, via the control switch 12, the micro air pump 9 can be started through the electronic control board 10. The micro air pump 9 can draw in outside air through the air inlet 2, pressurize it, and then deliver it to the inflation tube 6 through the air guide nozzle 8, thereby inflating the external device connected to the inflation tube 6. The lithium battery 11 can power the device, thus ensuring the device's battery life. Since the outer shell 1 is equipped with a protective ring 15, the protective effect of the outer shell 1 can be further enhanced, improving the service life of the air pump.

[0036] By supporting the inner shell 31 in component 3, it can be stably placed in the inner cavity of outer shell 1 via support ring 32, and space can be provided for the air guide hole 33. Then, the micro air pump 9 can be installed and fixed by positioning ring 34 and positioning plate 35, thereby improving the stability of micro air pump 9 in use. The electronic control board 10 and lithium battery 11 can be installed and fixed by isolation plate 36. Then, the filter screen plate 37 can be engaged and limited by two claws 38 on support ring 32, so that filter screen plate 37 can filter the gas entering the air guide hole 33, thereby preventing external dirt from clogging micro air pump 9. The air guide nozzle 8 can be engaged and limited by the locking hole 7, thereby improving the stability of air guide nozzle 8 in use.

[0037] In summary, this device can inflate air mattresses, bubble bath tubs, and inflatable swimming pools, and also extend the service life of the equipment itself.
