Description

Technical Field

[0001] The present invention relates to the technical field of air pumps, and in particular to a portable intelligent air pump with a double-cavity heat dissipation channel. Background Art

[0002] As a key component of outdoor adventure, emergency rescue and daily life auxiliary equipment, the performance optimization and technological innovation of portable smart air pumps have always been the focus of industry attention. However, the design framework of traditional portable smart air pumps often ignores the balance between structural compactness and thermal management efficiency while pursuing functionality. This defect is particularly significant when the equipment is in continuous operation.

[0003] Specifically, the internal components of traditional air pumps, especially the battery module and the compression cylinder, generate significant heat accumulation during the inflation process due to the conversion of electrical energy and mechanical stress. The current heat dissipation strategies, such as relying on natural air convection or simple heat dissipation fin design, are limited by the surface area and heat conduction path, and it is difficult to effectively dissipate the internal accumulated heat. This not only accelerates the decline of battery performance and shortens the use time after a single charge, but also causes the sealing performance to deteriorate due to the thermal expansion of the cylinder, which directly affects the output efficiency and stability of the air pump.

[0004] On a deeper level, the continuous high temperature environment forces the air pump motor to increase energy consumption to maintain a given working pressure, further exacerbating energy waste and equipment wear, and reducing the overall system's working efficiency and service life. Therefore, under the existing technical framework, the limitations of portable intelligent air pumps in heat dissipation efficiency and energy consumption control have become a key bottleneck restricting their performance improvement and widespread application.

[0054] In the field of portable smart air pump technology, traditional designs often ignore the balance between structural compactness and thermal management efficiency, especially during continuous operation. The internal components of the air pump, especially the battery module and the compression cylinder, generate a lot of heat due to electrical energy conversion and mechanical stress during the inflation process. Current heat dissipation strategies, such as natural convection or simple heat dissipation fins, are limited by the surface area and heat conduction path, making it difficult to dissipate heat effectively. This not only causes battery performance to deteriorate and shortens the service life, but also affects the sealing performance due to the thermal expansion of the cylinder, reducing the output efficiency and stability of the air pump. In addition, the high temperature environment forces the motor to increase energy consumption to maintain the working pressure, aggravating energy waste and equipment wear, and reducing the system's working efficiency and service life. Therefore, heat dissipation efficiency and energy consumption control have become bottleneck issues that restrict the performance improvement and widespread application of portable smart air pumps.

[0055] To solve the above problems, please refer to Figures 1 to 9The embodiment of the present invention provides a portable intelligent air pump with a dual-chamber heat dissipation channel, comprising:

[0056] The housing 10, as the main supporting structure of the intelligent air pump, ensures the stable installation of various components.

[0057] The shell cover 20 is installed on the shell body 10, and together with the shell body 10, forms a first heat dissipation channel cavity 11 and a second heat dissipation channel cavity 12. The structural coordination between the two improves the overall sealing and heat dissipation performance. The first heat dissipation channel cavity 11 and the second heat dissipation channel cavity 12 are adjacently and parallelly arranged to optimize the spatial layout. The first heat dissipation channel cavity 11 is a heat dissipation through cavity, which ensures the air circulation efficiency.

[0058] The air pump module 30 is installed on the first heat dissipation channel cavity 11, and uses the airflow formed in the first heat dissipation channel cavity 11 by the negative pressure suction when the air pump module 30 is working to dissipate heat, thereby improving the heat dissipation effect. The shell 10 and the shell cover 20 are both convexly provided with a guide arc plate 13, which plays a role in guiding the airflow. The guide arc plate 13 is arranged at the air inlet end of the first heat dissipation channel cavity 11, and the two guide arc plates 13 together constitute a guide ring 14, which accelerates the airflow speed by narrowing the airflow channel and improving the heat dissipation efficiency. Specifically, the air inlet port diameter of the guide ring 14 is larger than the air outlet port diameter, forming a Venturi effect and enhancing the heat dissipation effect. The air inlet end of the air pump module 30 is located on the side close to the guide ring 14. The air pump module 30 is used to supply air to the external equipment and the second heat dissipation channel cavity 12 at the same time, so as to realize multiple uses of one pump and reduce energy consumption and cost.

[0059] The integrated circuit board 40 is mounted on the housing 10 and is used to control the air pump module 30 to achieve intelligent operation and control.

[0060] The power module 50 is installed on the second heat dissipation channel cavity 12 in a gap-fitting manner, and uses the airflow in the second heat dissipation channel cavity 12 to dissipate heat, thereby improving the heat dissipation efficiency, ensuring the stable operation of the power module 50, and reducing energy consumption. The housing 10 is provided with a first heat dissipation outlet 15 connected to the second heat dissipation channel cavity 12 to accelerate the discharge of hot air and improve the heat dissipation efficiency. The air pump module 30 and the integrated circuit board 40 are both electrically connected to the power module 50 to ensure the power supply of the entire system and the transmission of control signals.

[0061] In this example, see Figures 2 to 5, the power module 50 is detachably mounted on the second heat dissipation channel cavity 12 through the heat dissipation plate frame 60. This design facilitates the maintenance and replacement of the power module 50. At the same time, the heat dissipation plate frame 60 acts as an intermediary to effectively improve the heat conduction efficiency between the power module 50 and the second heat dissipation channel cavity 12. A plurality of first guide grooves 61 are provided on the side of the heat dissipation plate frame 60 close to the power module 50. These first guide grooves 61 can guide the airflow, increase the heat dissipation area, and accelerate the conduction and dissipation of heat. A guide heat dissipation plate 70 is also installed on the second heat dissipation channel cavity 12 to further enhance the heat dissipation effect. The guide heat dissipation plate 70 is arranged on the side of the power module 50 away from the heat dissipation plate frame 60 and is located between the power module 50 and the housing 10. Such a layout ensures that the airflow can flow evenly through the power module 50. A plurality of second guide grooves 71 are provided on the side of the heat dissipation plate 70 close to the power module 50. These second guide grooves 71 work together with the first guide grooves 61 to form a more efficient heat dissipation channel and enhance the heat dissipation performance. The integrated circuit board 40 is installed on the side of the heat sink frame 60 away from the power module 50 and is located between the heat sink frame 60 and the shell cover 20. This layout not only protects the integrated circuit board 40 from external interference, but also utilizes the heat dissipation performance of the heat sink frame 60 to ensure the stable operation of the integrated circuit board 40.

[0062] The diameter of the air inlet of the first guide groove 61 and the second guide groove 71 are both smaller than the diameter of the air outlet. This design can accelerate the air flow rate, form a negative pressure effect, and further improve the heat dissipation efficiency. The heat dissipation plate frame 60 and the guide heat dissipation plate 70 are both heat dissipation metal plates with good thermal conductivity and heat dissipation. They can quickly conduct and dissipate the heat generated by the power module 50 and the integrated circuit board 40 to ensure the stable operation of the entire system.

[0063] For further information, see Figure 8 and Fig. 9 , the air pump module 30 comprises:

[0064] The bottom plate 31 is fixedly mounted on the housing 10 to provide a stable supporting foundation for the entire air pump module 30 .

[0065] The driving component 32 is installed at one end of the bottom plate 31 close to the guide ring 14 and is electrically connected to the power module 50 and the integrated circuit board 40 . It receives electric drive and converts it into mechanical energy to drive the operation of the air pump module 30 .

[0066] The pump body 33 is installed at one end of the bottom plate 31 away from the driving component 32. As the core component of the air pump module 30, it is responsible for generating air pressure and airflow. The pump body 33 is provided with a pump chamber 331, in which a piston is installed. The pump chamber 331 provides a space for the piston to move back and forth to achieve gas compression and discharge. The air inlet end of the pump chamber 331 is connected to the first heat dissipation channel cavity 11 to ensure that the pump body 33 can obtain sufficient airflow and form negative pressure suction in the first heat dissipation channel cavity 11.

[0067] The transmission gear disc 34 is arranged between the driving component 32 and the pump body 33 and is rotatably mounted on the bottom plate 31 as a key component for power transmission. The driving end of the driving component 32 is meshed and connected with the transmission gear disc 34 to convert the rotational power of the driving component 32 into the rotational motion of the transmission gear disc 34. The transmission gear disc 34 drives the piston to reciprocate along the length direction of the pump chamber 331 through the connecting rod 35 to achieve gas compression and discharge.

[0068] The inflation nozzle 36 is protrudingly disposed on a side of the pump body 33 away from the transmission gear plate 34, and is used to connect to an external device to deliver the compressed gas to the external device.

[0069] The one-way branch pipe 37 is arranged beside the inflation nozzle 36 and installed on the pump body 33 as a gas diversion channel. The one-way branch pipe 37 and the inflation nozzle 36 are both connected to the pump chamber 331 to ensure that the gas can flow in the set direction to achieve their respective functions. Among them, the one-way function of the one-way branch pipe 37 is limited to prevent the occurrence of backflow and avoid the repeated compression of the hot air flow, which affects the efficiency of inflation and heat dissipation. Please refer to Figure 7 A bridge pipe 62 is provided on the heat dissipation plate frame 60 for connecting to the outlet end of the one-way branch pipe 37. The bridge pipe 62 is connected to the second heat dissipation channel cavity 12. This design not only realizes the effective utilization of gas, but also provides additional airflow for the second heat dissipation channel cavity 12, thereby enhancing the heat dissipation effect.

[0070] Among them, see Fig. 9 The outer peripheral side of the pump body 33 is provided with heat dissipation fins 332, which effectively increase the heat dissipation area of ​​the pump body 33 and improve the heat dissipation efficiency of the pump body 33. A drainage groove 333 is provided between every two heat dissipation fins 332 on the side of the pump body 33 close to the shell cover 20, which can guide the airflow to flow more smoothly through the heat dissipation fins 332 and improve the heat dissipation effect. The air inlet diameter of the drainage groove 333 is larger than the air outlet diameter, forming a secondary Venturi effect, which cooperates with the guide ring 14 to further enhance the heat dissipation performance.

[0071] See also Figure 3 and Figure 4The end of the heat sink frame 60 away from the guide ring 14 is equipped with an external socket integration 80. This design allows users to easily connect an external power source or other devices through the external socket integration 80. The external socket integration 80 is electrically connected to the power module 50 to ensure stable power transmission and realize the charging and discharging function. The housing 10 is provided with an avoidance through hole 16 corresponding to the external socket integration 80, which provides convenience for the installation and use of the external socket integration 80. Please refer to Figure 7 A scattering plate 63 is also provided between the external socket integration part 80 and the power module 50, which cooperates with the first guide groove 61 and the second guide groove 71 to guide the airflow to flow more evenly through the upper and lower sides of the power module 50, thereby improving the heat dissipation efficiency. The scattering plate 63 can be detachably mounted on the heat dissipation plate frame 60 for easy maintenance and replacement, and is connected to the bridge tube 62 to achieve airflow conduction and ensure the realization of the fluid scattering function.

[0072] See also Figure 8 One end of the connecting rod 35 penetrates into the pump chamber 331 and is fixedly connected to the piston member, and the other end is rotatably mounted on the outer peripheral edge of the transmission gear disc 34, thereby ensuring the stability and reliability of the transmission. An air pressure sensor 361 is mounted on the inflation nozzle 36, and the air pressure sensor 361 is used to monitor the inflation pressure of external equipment to ensure the accuracy and safety of the inflation process. A thread 371 is also provided on the outer peripheral side of the one-way branch pipe 37. This design facilitates users to connect different accessories or pipelines as needed, thereby improving the versatility and flexibility of the equipment. In the event of emergency, the one-way branch pipe 37 can also be used as a second inflation pipeline, thereby achieving multiple uses of one machine.

[0073] For further information, see Figure 5 The side of the second heat dissipation channel cavity 12 away from the first heat dissipation channel cavity 11 is also provided with a stop frame member 90. This design not only provides a stable support for the power module 50, but also optimizes the heat dissipation structure. The side of the stop frame member 90 close to the first heat dissipation channel cavity 11 is in contact with the power module 50. The stop frame member 90 is also provided with a grille slot 91. The stop frame member 90 is a heat-conducting metal member. The stop frame member 90 has good heat conductivity and can conduct away the heat generated by the side of the power module 50. The design of the grille slot 91 can ensure that the airflow emitted by the scattering flow plate 63 flows smoothly and evenly to take away the heat, further improving the heat dissipation efficiency.

[0074] See also Figure 1 , Figure 3 and Figure 6The shell 10 is provided with an air inlet 17 and a second heat dissipation outlet 18 corresponding to the air inlet and air outlet of the first heat dissipation channel cavity 11, respectively, providing a channel for the airflow circulation in the first heat dissipation channel cavity 11. The first heat dissipation outlet 15 is located at one end of the second heat dissipation channel cavity 12 away from the second heat dissipation outlet 18, and is arranged on the side of the second heat dissipation channel cavity 12 away from the first heat dissipation channel cavity 11. Such a layout avoids mutual interference between airflows, improves heat dissipation performance, and makes the fluid path inside the intelligent air pump present a "μ" shape. The shell 10 is also provided with a third heat dissipation outlet 19, which is connected to the first heat dissipation channel cavity 11 and is located directly below the air outlet of the air pump module 30, so that the heat generated by the air pump module 30 can be discharged in time.

[0075] See also Figure 4 and Figure 6 The integrated circuit board 40 is integrated with a control module 41 and a display module 42. This design improves the intelligence of the device. The shell cover 20 is provided with an avoidance slot 21 corresponding to the control module 41. A keypad 22 for operating the control module is installed on the avoidance slot 21, so that the user can conveniently control the operation of the intelligent air pump. The shell cover 20 is also equipped with a transparent protective cover 23 corresponding to the display module 42. This design not only protects the display module 42 from external interference, but also ensures that the user can clearly view the use status and information of the intelligent air pump.
