[0047] Example

[0048] This embodiment aims to address the common problem in existing portable electric air pumps that lack a memory function. Each time they are used, the user needs to reset the target pressure value. This repetitive operation is inconvenient for users who frequently need to inflate the same type of containers, reducing the product's usability and efficiency. Therefore, referring to... Figures 1-3 As shown, an intelligent electric air pump is provided that integrates real-time pressure monitoring, automatic pump stop at preset pressure, and pressure value memory storage.

[0049] Reference Figures 1-3 As shown, an intelligent electric air pump device includes a housing 100, an electric drive assembly 200, a pressure detection component 300, a main control circuit board 400, a control panel 500, and a battery component 600.

[0050] The electric drive assembly 200 is disposed inside the housing 100. The electric drive assembly 200 includes an inflation port 110 for connecting to the target container. The inflation port 110 extends out of one end surface of the housing 100. The electric drive assembly 200 is used to compress outside air and pump it into the target container.

[0051] The pressure detection component 300 includes a pressure sensor, the detection end of which is disposed in the inflation port 110 and detects the air pressure in the inflation port 110.

[0052] The main control circuit board 400 is located inside the housing 100. The main control circuit board 400 is equipped with a main control chip, which is electrically connected to the electric drive assembly 200 and the pressure detection component 300.

[0053] The control panel 500 is disposed on the surface of the housing 100 and is electrically connected to the main control chip; the control panel 500 includes a display screen 510 and control buttons 520.

[0054] The battery component 600 is located inside the housing 100 and is electrically connected to the main control chip.

[0055] The main control chip can acquire pressure values ​​in real time through the pressure sensor and display them on the display screen 510; when the real-time pressure value reaches the preset pressure value, the control electric drive component 200 stops working and stores the preset pressure value set by the user through the control button 520 into the main control chip.

[0056] Understandably, the pressure sensor in the pressure detection component 300 can sense changes in air pressure within the inflation port 110 and transmit the data to the main control chip. The main control chip, through its built-in intelligent algorithm, can quickly calculate the current air pressure value and display it on the display screen 510, allowing users to easily monitor the air pressure in real time.

[0057] For example, the display screen 510 on the control panel 500 may be an LED digital tube display screen 510.

[0058] Furthermore, the main control chip also features a memory storage function, automatically saving the user's last preset pressure value. Understandably, when the user uses the electric air pump again, there's no need to reset the target pressure value; the pump will automatically inflate according to the previously saved pressure, greatly improving the product's ease of use and efficiency. This is particularly suitable for users who frequently need to inflate similar containers, such as sports balls, tires, paddleboards, and balloons, providing a more convenient user experience.

[0059] Reference Figures 1-3 As shown, in some embodiments, the electric drive assembly 200 includes a pressure relief valve 240, which is disposed on one side of the pipeline connecting to the inflation port 110. The press end of the pressure relief valve 240 extends out of the surface of the housing 100 and is used to manually press and release the internal pressure when the internal pressure of the intelligent electric air pump device is too high. This enhances the safety performance of the intelligent electric air pump device. When the internal pressure of the target container that needs to be inflated rises abnormally due to sensor failure or user misoperation, the excessive pressure may damage the target container or even cause a safety accident. At this time, the user can quickly release the excessive internal pressure by simply pressing the press end of the pressure relief valve 240, effectively preventing potential safety hazards. The setting of the pressure relief valve 240 not only provides the user with an intuitive and easy-to-operate safety release mechanism, but also reflects the humanized and safety considerations of product design.

[0060] Reference Figures 1-3As shown, in some embodiments, a connecting hose 700 is also included. The connecting hose 700 is used to connect the inflation port 110 to the target container. The housing 100 has an internal storage compartment, the port of which extends out of the housing 100, and the connecting hose 700 can be housed within the storage compartment. This maintains the neatness of the device and facilitates the user's safe storage of the connecting hose 700 when carrying or storing the smart electric air pump, preventing the hose from becoming tangled or lost. For example, the port edge of the storage compartment is designed with a flexible snap or magnetic structure to ensure that the connecting hose 700 can be securely fixed in the storage compartment when not in use, preventing the hose from slipping accidentally and maintaining the smooth and aesthetically pleasing appearance of the housing 100. In addition, the design of the storage compartment also takes into account the ease of user operation, allowing the user to quickly and easily remove the connecting hose 700 from the storage compartment and connect it to the target container when inflation is needed, further improving the efficiency and user experience of the smart electric air pump device.

[0061] Reference Figures 1-3 As shown, in some embodiments, a lighting lamp 800 is also included. The lighting lamp 800 is disposed within the housing 100, and its illumination end is located on one side of the inflation port 110, for providing illumination for inflation operations in low-light environments. The design of the lighting lamp 800 takes into account the user's needs under different lighting conditions. When the user operates the intelligent electric air pump device in a dimly lit environment, the lighting lamp 800 can be manually turned on to emit light, illuminating the inflation port 110 and its surrounding area. This not only allows the user to more clearly observe the connection status between the inflation port 110 and the target container, ensuring the accuracy and safety of the inflation operation, but also improves the user's operating experience in low-light environments.

[0062] Reference Figures 1-3 As shown, in some embodiments, the battery component 600 includes a battery pack 610, a charge / discharge control chip, and a charging interface 630. The charge / discharge control chip is electrically connected to the battery pack 610; the charging interface 630 is embedded in the surface of the housing 100 and electrically connected to the charge / discharge control chip. The charge / discharge control chip is responsible for managing and monitoring the charging and discharging process of the battery pack 610. For example, the charging interface 630 can be an existing Type-C interface, Micro USB interface, or Lightning interface, etc. The charge / discharge control chip also has functions such as overcharge protection, over-discharge protection, and short-circuit protection to ensure the safe use of the battery pack 610. In addition, the battery component 600 may also include a battery power display module 640, such as red, yellow, and green lights to indicate low power, medium power, and full power, respectively. The battery power display module 640 is electrically connected to the charge / discharge control chip and is used to display the remaining power of the battery pack 610 in real time, reminding the user to charge in time and avoid affecting the charging effect due to insufficient power during use.

[0063] Reference Figures 1-3 As shown, in some embodiments, the control panel 500 includes a display screen 510 and control buttons 520, the control buttons 520 including:

[0064] Inflation switch 521 is used to open and close the electric drive assembly 200; and / or

[0065] Mode selection key 522 is used to switch inflation modes; and / or

[0066] Pressure setting key 523 is used to increase or decrease the preset pressure value; and / or

[0067] Lighting switch 524 is used to turn the lighting 800 on and off.

[0068] For example, the main control chip is equipped with a timer. Pressing and holding the inflation start / stop button 521 for three seconds will trigger the power-on function. After powering on, clicking the inflation start / stop button 521 will pause inflation. In the paused inflation state, the power-off function will be triggered after three minutes.

[0069] Reference Figures 1-3 As shown, in some embodiments, the electric drive assembly 200 includes a motor 210, an eccentric wheel linkage mechanism 220, and a cylinder 230.

[0070] The output end of the motor 210 is connected to the eccentric wheel linkage mechanism 220. A piston 231 is installed inside the cylinder 230, and the piston 231 is connected to the end of the eccentric wheel linkage mechanism 220. A first valve 232 is installed inside the cylinder 230, and the outlet of the first valve 232 is connected to the inflation port 110. The motor 210 drives the eccentric wheel linkage mechanism 220, which in turn drives the piston 231 to reciprocate linearly within the cylinder 230, thereby compressing air and pumping it to the inflation port 110. A second valve 233 is installed on one side of the cylinder 230 for air intake. The sealed connection between the piston 231 and the cylinder 230 effectively prevents gas leakage and improves the working efficiency of the intelligent electric air pump device. For example, the first valve 232 and the second valve 233 can be existing check valves. The second valve 233 opens in time to draw in outside air, while the first valve 232 opens quickly when pumping gas to send the compressed gas into the inflation port 110.

[0071] Reference Figures 1-3 As shown, in some embodiments, the housing 100 includes a housing body 101 and a housing cover 102.

[0072] The outer wall of the shell body 101 near the cylinder 230 has evenly distributed air holes 1011;

[0073] The cover 102 is detachably connected to the main body 101. The electric drive assembly 200, the main control circuit board 400, and the battery component 600 are respectively disposed between the main body 101 and the cover 102. Furthermore, the main body 101 and the cover 102 are detachably connected using snap-fit ​​or screw-like methods, facilitating user maintenance and component replacement. Key components such as the electric drive assembly 200, the main control circuit board 400, and the battery component 600 are securely fixed between the main body 101 and the cover 102, protecting these components from external environmental interference and ensuring the stable operation of the intelligent electric air pump device.

[0074] Reference Figures 1-3 As shown, in some embodiments, the eccentric wheel linkage mechanism 220 includes:

[0075] The fixed base 221 is disposed inside the housing 100, with one end connected to the cylinder body 230 and the other end connected to the motor 210; the fixed base 221 is provided with a rotating groove;

[0076] The rotating shaft 222 is disposed in the rotating groove and can rotate along the rotating groove;

[0077] The eccentric wheel 223 has a rotating groove extending from one end of the rotating shaft 222 and connected to the middle of the eccentric wheel 223. Gears are evenly distributed on the outer ring of the eccentric wheel 223, and the gears mesh with the drive gear at the output end of the motor 210.

[0078] The connecting rod 224 has one end rotatably connected to the non-center position of the eccentric wheel 223, and the other end is connected to the piston 231.

[0079] When the motor 210 starts, the drive gear drives the eccentric wheel 223 to rotate. Since the connecting rod 224 is connected to the non-central position of the eccentric wheel 223, the connecting rod 224 will reciprocate as the eccentric wheel 223 rotates. This reciprocating motion, in turn, drives the piston 231 to reciprocate within the cylinder 230, thereby realizing the intake and compression discharge of gas. This improves the working efficiency of the intelligent electric air pump device and ensures stable gas pumping. At the same time, the setting of the fixed base 221 enhances the stability of the entire mechanism, enabling the eccentric wheel linkage mechanism 220 to maintain a stable working state even when operating at high speed.

[0080] Reference Figures 1-3As shown, in some embodiments, the inflation port 110 is threadedly connected to the connecting hose 700. One end of the connecting hose 700 is provided with a first magnetic attraction part, and a second magnetic attraction part is provided inside the accommodating chamber, which is magnetically attracted to the first magnetic attraction part. The threaded connection between the inflation port 110 and the connecting hose 700 makes the connection between the connecting hose 700 and the inflation port 110 more secure and less prone to detachment. When it is necessary to connect or disconnect the connecting hose 700, the user only needs to simply rotate the connecting hose 700 to complete the operation, which is simple and quick. At the same time, the magnetic attraction between the first magnetic attraction part and the second magnetic attraction part further enhances the stability of the connection, ensuring a tight connection between the connecting hose 700 and the accommodating chamber even under vibration or external force.

[0081] For example, when a user inflates a paddleboard: the inflation port 110 is connected to the paddleboard's air nozzle via a connecting hose 700; the user presses and holds the inflation start / stop button 5213 seconds, and the device loads the previously saved paddleboard mode pressure preset value; the main control chip starts the motor 210, and the display screen 510 shows the pressure increase; when the device pressure reaches the preset value, the motor 210 stops; the user unplugs the connecting hose 700, and the device automatically shuts down after 3 minutes of inactivity.

[0082] The electronic devices provided in the embodiments of this application have been described in detail above. Specific examples have been used to illustrate the principles and implementation methods of this application. The descriptions of the embodiments above are only for the purpose of helping to understand this application. Furthermore, those skilled in the art will recognize that, based on the ideas of this application, there will be changes in the specific implementation methods and application scope. Therefore, the content of this specification should not be construed as a limitation of this application.
