[0002] Portable air pumps are widely used in daily life and various work scenarios, such as outdoor exploration, emergency rescue, or leisure sports, and can quickly inflate equipment such as tires, tents, and balls.

[0003] Traditional portable air pumps rely primarily on external power sources, such as vehicles, to provide power for inflation. This power supply method severely limits their application scenarios. For example, when there is no power supply in the field, the air pump cannot function properly, greatly restricting its usage.

[0004] To address the limitation of traditional portable air pumps in various application scenarios, existing technologies have proposed portable air pumps with built-in batteries. By equipping the pump with a battery, it becomes self-powered, thus overcoming the predicament of traditional air pumps being limited by external power sources.

[0005] However, since air pumps are not used frequently in daily life, prolonged idleness can lead to a decline in the performance of the built-in battery, resulting in a waste of battery performance and an increase in user costs. Utility Model Content

[0041] The technical solution of this utility model will be further described below with reference to the accompanying drawings and specific embodiments.

[0042] See Figures 1 to 13 The multifunctional air pump provided in this embodiment of the utility model includes an air pump body 1 and a battery assembly 2. The battery assembly 2 includes a battery body 21 and a multifunctional module 22 integrated into the battery body 21. The battery body 21 is detachably connected to the air pump body 1 and configured to supply power to the air pump body 1. The multifunctional module 22 includes at least one of a power module 221, a blower module 222, a heating module, and a lighting module 223.

[0043] The multi-functional air pump proposed in this utility model effectively solves the problem of traditional air pumps relying on external power sources, which limits their application scenarios, by setting up a battery assembly 2 detachably connected to the air pump body 1. The battery body 21 supplies power to the air pump body 1. This allows the air pump to work normally even without an external power source. The multi-functional module 22 integrated on the battery assembly 2 includes at least one of a power module 221, a fan module 222, and a lighting module 223, further expanding the air pump's functionality. The power module 221 can be used as a portable power source to charge other devices; the fan module 222 can provide auxiliary inflation functions such as inflating small air cushions or acting as a miniature fan; the heating module can be used as a portable heating device or tool; and the lighting module 223 can provide illumination in scenarios such as outdoor nighttime, meeting various needs. In summary, this multi-functional air pump, by configuring the multi-functional module 22 on the battery assembly 2, comprehensively improves the functionality and applicability of the air pump.

[0044] The specific structure and working principle of this multi-functional air pump will be described in detail below.

[0045] The air pump body 1 is mainly used to perform the inflation function. Its interior usually includes a motor, pump head and related air circuit structure to generate and transport airflow to realize the inflation operation of tires, balls or other inflatable objects.

[0046] It is understood that the improvement of this utility model does not lie in the mechanical or pneumatic structure of the air pump body 1 itself, but in the detachable connection structure between the air pump body 1 and the battery assembly 2, as well as the various functional modules integrated in the battery assembly 2. The specific structure and working principle of the air pump body 1 are conventional technologies related to this field and will not be described in detail here.

[0047] The function of the battery body 21 is to provide power for the operation of the air pump body 1. The specific internal battery structure of the battery body 21 is common knowledge in the field and will not be described in detail here.

[0048] To improve the portability and flexibility of the air pump, the battery body 21 and the air pump body 1 are detachably connected. The air pump body 1 has a charging contact 100, and the battery body 21 has a power supply contact 200. When the air pump body 1 and the battery body 21 are connected, the charging contact 100 and the power supply contact 200 are engaged, and the battery body 21 can supply power to the air pump body 1.

[0049] Optionally, the battery body 21 and the air pump body 1 are magnetically connected. The magnetic connection makes it easier to connect and disconnect the battery body 21 and the air pump body 1. When it is necessary to replace the battery body 21 or use other functions, the connection or disassembly can be completed by gently pulling and plucking. It is especially suitable for quick operation in low light or emergency situations.

[0050] Alternatively, the battery body 21 and the air pump body 1 can be plugged in, which can provide a stable connection between the two, ensuring that the battery body 21 will not fall off accidentally during the operation of the air pump, ensuring the stability of power supply, and improving the reliability of the air pump during use.

[0051] Alternatively, the battery body 21 and the air pump body 1 can be connected by a snap-fit ​​mechanism. This snap-fit ​​mechanism has the advantages of convenient installation and a firm connection. It can quickly install the battery body 21 and the air pump body 1 into place and can withstand a certain amount of external force to prevent the connection from becoming loose due to shaking or collision during use.

[0052] In this embodiment, one of the battery body 21 and the air pump body 1 is provided with a protruding ridge 3, and the other is provided with a groove 4 that matches the protruding ridge 3. The protruding ridge 3 can be engaged with the groove 4. During installation, the two can be connected by a simple snap-fit ​​action. During disassembly, only appropriate external force needs to be applied to separate the protruding ridge 3 from the groove 4. The operation is simple and quick, without the need for additional tools, and has high disassembly and assembly efficiency. Furthermore, after installation, the protruding ridge 3 and the groove 4 fit tightly, making the surface of the battery body 21 and the air pump body 1 relatively flat after connection, with smooth lines and no abruptness, improving the overall aesthetic appearance of the product. In addition, when the user holds the battery body 21 or the air pump body 1 alone, the protruding ridge 3 or the groove 4 can increase the friction between the hand and the surface of the device, preventing the device from slipping due to sweaty hands or unstable grip, thus improving the anti-slip performance of the device.

[0053] It should be noted that in this embodiment, the battery body 21 and the air pump body 1 are both provided with partial protrusions 3 and partial grooves 4, which cooperate to achieve connection. However, the connection structure of this utility model is not limited to this. In other feasible embodiments, the battery body 21 may be provided with grooves 4, and the air pump body 1 may be provided with corresponding protrusions 3. Alternatively, the positions of the protrusions 3 and grooves 4 may be interchanged, that is, the battery body 21 may be provided with protrusions 3, and the air pump body 1 may be provided with corresponding matching grooves 4. Any cooperative structure of protrusions 3 and grooves 4 implemented by equivalent substitution or equivalent transformation should be covered within the protection scope of this utility model.

[0054] Preferably, the width of the groove 4 is greater than the width of the opening. For example, the cross-section of the groove 4 is dovetail-shaped or inverted T-shaped, and the shape of the protruding rib 3 matches the groove 4, thus forming an anti-detachment structure. When the protruding rib 3 is inserted into the groove 4, its large main body is accommodated in the wider groove space, while the narrow opening forms a constraint structure, which can effectively prevent the protruding rib 3 from accidentally detaching from the groove 4 when subjected to a force perpendicular to the groove 4, thereby enhancing the vibration resistance and pull-out resistance after connection.

[0055] Furthermore, a limiting member 42 is provided at one end of the groove 4. When the protrusion 3 enters the groove 4 and abuts against the limiting member 42, the bottom surface of the battery body 21 is flush with the bottom surface of the air pump body 1. This design not only gives the air pump a neat and beautiful integrated appearance when connected, but also improves the stability and safety of the overall structure, preventing the protrusion 3 from slipping off the groove 4 during use and transportation. In addition, the limiting member 42 also provides users with clear and reliable installation instructions, making the placement more stable.

[0056] During installation, align the portion of the battery body 21 or the air pump body 1 with the protruding ridge 3 with the end of the groove 4 on the other component that has an opening and is away from the limiting member 42. Then, insert the protruding ridge 3 along the direction of the groove 4. As insertion proceeds, the protruding ridge 3 gradually penetrates deeper into the groove 4 until it abuts against the limiting member 42. At this point, the battery body 21 and the air pump body 1 are securely connected. During disassembly, apply appropriate external force in the opposite direction of the insertion of the protruding ridge 3 to overcome the friction between the protruding ridge 3 and the groove 4, causing it to detach from the limiting member 42 and be pulled out from the open end, thus separating the two components.

[0057] The protruding ridge 3 and the groove 4 extend along the length of the battery body 21, or along the width of the battery body 21, or at an angle. These different extension directions can meet the user's gripping habits and assembly / disassembly preferences in different usage scenarios, and can be adapted to actual needs; no specific limitations are imposed here.

[0058] Furthermore, one of the charging contact 100 and the power supply contact 200 is connected to the protrusion 3, and the other is located in the groove 4. The charging contact 100 and / or the power supply contact 200 are elastic. When the protrusion 3 is engaged with the groove 4, the charging contact 100 and the power supply contact 200 are electrically connected, thereby connecting the power supply circuit between the battery body 21 and the air pump body 1, and realizing the power supply operation of the air pump body 1.

[0059] Specifically, one of the charging contact 100 and the power supply contact 200 includes two elastic support members 41, which are symmetrically distributed and facing each other on the inner walls of the groove 4. When the protrusion 3 is engaged with the groove 4, the other of the charging contact 100 and the power supply contact 200 is clamped between the two elastic support members 41. The elastic support members 41 can provide additional elastic clamping force, enhancing the firmness of the electrical connection between the charging contact 100 and the power supply contact 200. Even if the air pump encounters vibration or shaking during operation, the electrical connection between the charging contact 100 and the power supply contact 200 is not easily disengaged, ensuring that the battery body 21 always maintains a stable power supply to the air pump body 1. At the same time, the elastic deformation of the elastic support members 41 can buffer external forces. When the air pump is subjected to external impact, the elastic support members 41 can absorb part of the impact force, reducing damage to the charging contact 100 and the power supply contact 200.

[0060] In this embodiment, the elastic support 41 is a conductive metal spring sheet, which is bent in a D shape and its two ends are fixedly connected to the inner wall of the groove 4.

[0061] Furthermore, one of the charging contact 100 and the power supply contact 200 includes a locking protrusion 31 connected to the protrusion 3. When the protrusion 3 is engaged with the groove 4, the other of the charging contact 100 and the power supply contact 200 abuts against the locking protrusion 31. The pressure of the locking protrusion 31 allows the charging contact 100 and the power supply contact 200 to fit more tightly, providing a stronger clamping force and effectively preventing loosening or displacement of the charging contact 100 and the power supply contact 200. The locking protrusion 31 is made of conductive metal and corresponds to the position of the elastic support member 41. When the locking protrusion 31 is inserted between the two elastic support members 41, the charging contact 100 and the power supply contact 200 are electrically connected, thereby connecting the power supply circuit between the battery body 21 and the air pump body 1.

[0062] In the multifunctional air pump provided by this utility model, the battery assembly 2 not only serves as a detachable power source for the air pump body 1, but also expands its functionality and practicality when used independently by integrating multiple functional modules. When the battery body 21 is separated from the air pump body 1, the user can use its integrated multifunctional module 22 independently according to actual needs, thereby improving battery utilization and enriching application scenarios. The specific structure and implementation methods of these multifunctional modules 22 will be described in detail below.

[0063] The power module 221 in the multi-functional module 22 is integrated into the battery body 21. Its core function is to function as an independent portable power bank after the battery body 21 is detached from the air pump body 1. The power module 221 includes one or more power output interfaces, such as USB-A interfaces, Type-C interfaces, or DC round hole interfaces, on the outer shell of the battery body 21, for supplying power to external electrical devices. The electrical energy stored inside the battery body 21 can be output through these interfaces to provide power to mobile phones, tablets, lights, or other portable electronic products.

[0064] In addition, the power module 221 also integrates necessary charge and discharge management circuits and status indication units to safely and efficiently manage the battery's power output process and display the current power level or operating status, providing users with intuitive feedback.

[0065] The air pump module 222 in the multi-functional module 22 is integrated into the battery body 21. When the battery body 21 is separated from the air pump body 1, the air pump module 222 can be started independently, and its core function is to be used as a portable miniature fan. The air pump module 222 includes a miniature motor, an impeller driven by the motor, and a protective mesh or grille structure. After starting, the impeller rotates to generate directional airflow, providing a blowing function for the user, especially in hot outdoor environments, effectively bringing a cooling sensation and improving comfort.

[0066] The heating module in the multi-functional module 22 is integrated into the battery body 21. The heating module includes one or more heating films, a control unit for controlling heating power and temperature, a protective shell, and an operating switch. The heating films are typically made of flexible, bendable materials to easily fit the internal structure of the battery shell; the control unit has basic temperature regulation and overheat protection functions to ensure safe use; the shell is made of thermally conductive and insulating materials, effectively transferring heat while preventing accidental burns. Upon activation, electrical energy is converted into heat energy and evenly dissipated through the shell. This module can be designed with different power output modes, such as low-level heating and high-level rapid heating, to meet diverse usage needs.

[0067] The lighting module 223 in the multi-functional module 22 is integrated into the battery body 21. When the battery body 21 is removed from the air pump body 1, the lighting module 223 can be activated independently, its core function being to function as a portable lighting device. The lighting module 223 includes one or more high-brightness LED beads, a lampshade or light guide for light distribution, and a switch to control the lighting mode (such as high light, low light, flashing SOS signal, etc.). Upon activation, the LED beads emit light, providing stable and reliable lighting support for users' activities at night or in low-light environments, such as outdoor camping, nighttime maintenance, emergency navigation, or calling for help.

[0068] It should be noted that the power module 221, fan module 222, heating module, and lighting module 223 mentioned above can be adaptively selected and combined according to the actual product functional requirements. The multi-functional module 22 can contain only one of these modules, or a combination of any two or three modules, or all four modules simultaneously. This modular design allows the product to flexibly adapt to different market positioning and user needs, enriching the product series while optimizing the cost structure. In specific implementation, the number and type of modules can be configured according to actual design requirements, which will not be elaborated here.

[0069] The above embodiments merely illustrate the basic principles and characteristics of this utility model. This utility model is not limited to the above embodiments. Various changes and modifications can be made to this utility model without departing from its spirit and scope, and all such changes and modifications fall within the scope of the claimed utility model.
