[0028] It should be noted that, in the absence of conflict, the embodiments and features of the embodiments in this application can be combined with each other. Now, in conjunction with the accompanying drawings, a detailed description of the preferred embodiments of the present utility model will be given.

[0029] The present invention provides an electric inflatable device. Figures 1 to 3 As shown, the electric inflation device includes a shell 1, an air pump 2, an air inflation tube 3, a rear frame 4 and a rear cover 5; the shell 1 includes a first shell 11 and a second shell 12, the first shell 11 and the second shell 12 are installed in a pair and form a spaced installation cavity 13 and a storage cavity 14 in the shell 1, and the storage cavity 14 is arranged near the rear end face 19 of the shell 1.

[0030] The air pump 2 is installed in the installation cavity 13, the air tube 3 is connected to the air pump 2 and is led from the installation cavity 13 to the storage cavity 14; the rear frame 4 is installed on the rear end surface 19 of the shell 1 and is respectively connected to the first shell 11 and the second shell 12, and the rear frame 4 is provided with a frame opening 41 connected to the storage cavity 14; the rear cover 5 is installed on the frame opening 41 so as to be closed and opened.

[0031] The first shell 11 and the second shell 12 of the electric inflatable device of the present invention are installed together to form the shell 1 of the electric inflatable device, and a spaced-apart installation cavity 13 and a storage cavity 14 are formed in the shell 1. The installation cavity 13 is used to install the air pump 2, and the storage cavity 14 can facilitate the storage of the air inflatable tube 3, ensuring the convenience of production assembly and use and storage. At the same time, by installing the rear frame 4 on the rear end face 19 of the shell 1, the rear frame 4 is connected to the first shell 11 and the second shell 12 respectively, and the rear cover 5 is installed on the rear frame 4. Therefore, the rear frame 4 can play the role of the connector 9 to further connect and strengthen the connection between the first shell 11 and the second shell 12, improve the overall structural stability of the shell 1, and avoid damage caused by external factors such as falling and moving. At the same time, the rear frame 4 provides a mounting position for the rear cover 5 to ensure that the storage cavity 14 is closed by the rear cover 5.

[0032] Specifically, when the air pump 2 is working, gas is generated by the air pump 2 and output through the inflation tube 3. The inflation tube 3 is drawn out from the storage chamber 14 and connected to the inflation object to inflate the inflation object. The first shell 11 and the second shell 12 can be further connected and fixed by structures such as snaps and screws, which will not be repeated here. The electric inflation device also includes a control circuit board and a power cord 8. The control circuit board is installed in the installation chamber 13. The power cord 8 is electrically connected to the control circuit board and is drawn from the installation chamber 13 to the storage chamber 14. The air pump 2 can be directly connected to the mains power through the power cord 8 to work. When not in use, the power cord 8 and the inflation tube 3 can be rolled up and stored in the storage chamber 14. When in use, the back cover 5 is opened again, and the power cord 8 and the inflation tube 3 are pulled out from the storage chamber 14 for use.

[0033] Further integration Figure 4 、 Figure 6 and Figure 7As shown, the inner wall surfaces of the first and second housings 11 and 12 on one side near the rear frame 4 are each provided with a hook portion 15 and a stopper protrusion 16. Each hook portion 15 is arranged opposite a corresponding stopper protrusion 16 to form a pair. A snap-fitting piece 42 is provided on the edge of the rear frame 4, corresponding to each pair of hook portions 15 and stopper protrusions 16. The snap-fitting piece 42 has a snap-fitting interface 421 defined therein. The hook portion 15 and stopper protrusion 16 snap into the snap-fitting interface 421 of the corresponding snap-fitting piece 42. By providing a hook portion 15 and a limiting protrusion 16 on the inner wall surfaces of the first and second housings 11 and 12, and providing a snap plate 42 and a snap interface 421 on the edge of the rear frame 4, the relatively arranged hook portion 15 and limiting protrusion 16 form a limit on the snap interface 421. The hook portion 15 engages the snap interface 421 through its hook, while the limiting protrusion 16 blocks the snap interface 421 and assists the hook portion 15. The two work together to ensure the connection strength between the housing 1 and the rear frame 4, making the connection between the housing 1 and the rear frame 4 more stable and improving the structural stability of the entire electric inflator. The design of the hook portion 15 and limiting protrusion 16 also simplifies the assembly process. During assembly, simply align the hook portion 15 and the limiting protrusion 16 with the snap interface 421 of the snap plate 42 and then gently press to complete the assembly. This quick snap-in design improves production efficiency and reduces assembly time. Furthermore, due to the design of the hook portion 15 and the engaging piece 42, the first housing 11 and the second housing 12 can be easily disassembled. This is very convenient when the electric inflatable device needs to be maintained or parts replaced, because the user can quickly disassemble the housing 1 without using tools.

[0034] Specifically, a hook portion 15 and a limiting protrusion 16 are relatively arranged as a group, and each group of hook portion 15 and limiting protrusion 16 is clamped in the clamping interface 421 of a clamping piece 42. Each group of hook portion 15 and limiting protrusion 16 is relatively arranged in the front-to-back direction of the housing 1.

[0035] A stopper 17 is provided on the inner wall of each of the first and second housings 11 and 12, which is adjacent to the rear frame 4. The stopper 17 abuts against the inner side of the rear frame 4. The stopper 17 further blocks and positions the rear frame 4, facilitating precise alignment during assembly. Furthermore, the stopper 17 supports the edge of the rear frame 4, improving its installation stability and load-bearing capacity.

[0036] A partition 18 is provided on the inner wall surfaces of the first shell 11 and the second shell 12. The partition 18 separates the installation cavity 13 and the storage cavity 14 in the shell 1. The partition 18 clearly divides the internal space of the shell 1 into two functional areas: the installation cavity 13 and the storage cavity 14. The installation cavity 13 is used to install the air pump 2 and other key components, such as the main control circuit board mentioned above and the battery pack 7 described below, while the storage cavity 14 is used to store accessories such as the air tube 3 and the power cord 8. This design makes the internal layout of the entire device more reasonable and orderly. In addition, the provision of the partition 18 can maximize the utilization of the internal space of the shell 1. The separation of the installation cavity 13 and the storage cavity 14 ensures that each component has a dedicated storage location, avoiding space waste and facilitating assembly and maintenance. The design of the partition 18 can also protect the air pump 2 and other electronic components installed in the installation cavity 13 from interference with the air tube 3 and power cord 8 stored in the storage cavity 14, thereby improving the reliability and durability of the electric inflatable device. Furthermore, partition 18 separates storage cavity 14 from mounting cavity 13, allowing for more organized storage of the gas tube 3 and power cord 8, making them easier to manage and use. During use, the user can easily remove the gas tube 3 and power cord 8 from storage cavity 14 without disturbing the components in mounting cavity 13. Furthermore, partition 18 not only divides the space but also enhances the structural stability of housing 1. It acts as a reinforcing rib, increasing the rigidity of housing 1 and reducing deformation caused by external impacts.

[0037] The partition 18 is provided with a plurality of air inlet holes 181, which connect the mounting chamber 13 and the storage chamber 14. One end of the air pump 2 is provided corresponding to the air inlet holes 181 and is equipped with an air intake fan 6. The air intake fan 6 introduces external air into the mounting chamber 13 through the air inlet holes 181, which can improve the air circulation efficiency of the air pump 2 during operation, thereby helping to improve the inflation speed and performance.

[0038] The air pump 2 also includes a battery pack 7, which is mounted in the portion of the mounting cavity 13 located in front of the storage cavity 14. The battery pack 7 is mounted in the portion of the mounting cavity 13 located above the storage cavity 14. By mounting the battery pack 7 and the air pump 2 above and in front of the storage cavity 14, respectively, the space within the housing 1 can be more efficiently utilized. This layout facilitates a compact design for the air pump 2 while ensuring that the functions of each component are not affected. Mounting the battery pack 7 above the storage cavity 14 separates it from the air pump 2, reducing the impact of heat generated by the air pump 2 on the battery pack 7 and thus improving the safety of the entire device. The battery pack 7 includes multiple battery cells, which can be further mounted in the portion of the mounting cavity 13 located above the storage cavity 14 via a battery holder. The battery pack 7 is electrically connected to the main control circuit board, thereby powering the air pump 2. In other words, the air pump 2 can operate via power cord 8 or be charged via the rechargeable battery pack 7.

[0039] The outer side of the rear frame 4 is provided with a receiving groove 43 surrounding the frame opening 41, and the rear cover 5 is received in the receiving groove 43. By providing the receiving groove 43 on the rear frame 4 to receive the rear cover 5, it is ensured that the rear cover 5 does not protrude from the rear frame 4 when closed, thereby improving the overall structure and reducing the volume.

[0040] A first interface 431 is provided on the upper side of the receiving slot 43, and the back cover 5 covers this interface 431. Covering this interface protects it from dust, moisture, and other potential contaminants, thereby extending its lifespan and reducing maintenance. Covering the interface also enhances the device's appearance, making it more neat and aesthetically pleasing. The absence of exposed interfaces enhances the overall aesthetic quality of the product. When the first interface 431 is needed, the user can easily remove the back cover 5 and connect the appropriate device or cable. After use, the back cover 5 can be re-covered to restore its protection. The first interface 431 can be a Type-C charging port, which is electrically connected to the main control circuit board to charge the battery pack 7. Multiple placement cavities 432 are defined on the upper side of the receiving slot 43. The electric inflator includes multiple air nozzles 31, each housed in a placement cavity 432. Each cavity 432 can accommodate different air nozzles 31, allowing the inflator tube 3 to be replaced with a corresponding air nozzle 31 for different inflatable objects, improving ease of use.

[0041] Combine Figure 1 、 Figure 4 and Figure 5 As shown, there is a gap between the top edge of the rear cover 5 and the top edge of the receiving slot 43. A finger-grip groove 51 is defined on the inner side of the top edge of the rear cover 5. This gap provides space for the operator to apply force to the finger-grip groove 51 to engage the rear cover 5. The bottom of the rear cover 5 can be connected to the bottom edge of the frame opening 41 via a connector 9. The connector 9 can be a conventional connecting hook, with one end mounted on the bottom edge of the frame opening 41 and the other end provided with a hook that movably engages a mounting hole on the inner side of the rear cover 5. The details will not be repeated here.
