Description

Technical Field

[0001] This utility model belongs to the technical field of air filling equipment and relates to a flow-guiding self-heating air pump. Background Technology

[0002] Air pumps are increasingly used in home and outdoor camping settings, but existing products generally suffer from inadequate structural design. When inflating gas, small air pumps are prone to overheating and slow heat dissipation due to the need for continuous air supply, leading to slower inflation or even motor damage. Large air pumps, while requiring additional cooling modules, often become bulky and heavy. Therefore, there is an urgent need to design a compact, miniaturized air pump with excellent heat dissipation. Utility Model Content

[0003] To address the aforementioned problems, this utility model provides a flow-guided self-cooling air pump, comprising a fan, a power module, a circuit board, a control module, and a housing. The housing encapsulates the fan, power module, circuit board, and control module. The fan, power module, circuit board, and control module are electrically connected. The control module is used to control start and stop. The fan includes a fan body and cooling fins. The cooling fins are connected to the fan body via support arms. An air guide port is provided between the support arms. Airflow is pumped into the fan through the air inlet of the housing, then blown out of the air guide port, and finally blown out of the air guide port to the air outlet of the housing.

[0004] Furthermore, it also includes a fan housing, which encloses and encapsulates the fan and has through holes for airflow in and out. The fan housing also has air-gathering holes in the airflow outward direction.

[0005] Furthermore, the fan housing includes a front cover and a rear cover, which are matched to each other and enclose the fan. The front cover is provided with a wind deflector.

[0006] Furthermore, the wind cover guide plate is composed of several wind cover guide sub-plates, and the shoulders of the wind cover guide sub-plates are stepped, sloping, or arc-shaped.

[0007] Furthermore, the front cover and rear cover of the fan are provided with matching through holes, which are connected and fixed to the outer shell.

[0008] Furthermore, it also includes an air inflator, and the flow-guided self-cooling air pump and the air inflator are provided with a matching docking and fixing structure.

[0009] Furthermore, the docking and fixing structure is configured as a slot on the blower housing and a protrusion on the inflation adapter, wherein the protrusion can be rotated and slid into the slot to achieve locking and fixing.

[0010] Furthermore, at least a portion of the circuit board is integrated onto the cooling plate.

[0011] Furthermore, the cooling fin is provided with a cooling fin guide plate.

[0012] Furthermore, the power module is disposed inside the handle of the housing, at least a portion of the circuit board is disposed at the bottom of the power supply, and the control module is disposed on the handle of the housing.

[0013] The beneficial effects of this utility model are as follows: This application adopts an innovative integrated air duct design, which designs the fan as a fan body and a cooling plate. On the one hand, the cooling plate changes the flow mode of the airflow, prolongs the flow time of the airflow in the fan, and thus increases the space and time for heat exchange. On the other hand, when a heat-generating circuit is set on the cooling plate, the airflow carries away the heat when it flows through the cooling plate, thereby reducing the heating temperature of the air pump. At the same time, the goals of miniaturization and easy heat dissipation are achieved. Attached Figure Description

[0027] Example 1

[0028] like Figure 1-3As shown, this utility model provides a flow-guided self-cooling air pump, including a fan 1, a power module 2, a circuit board 3, a control module 4, and a housing 5. The housing 5 encapsulates the fan 1, power module 2, circuit board 3, and control module 4. The fan 1, power module 2, circuit board 3, and control module 4 are electrically connected. The control module 4 is used to control the start and stop. The fan 1 includes a fan body 11 and a cooling fin 12. The cooling fin 12 is connected to the fan body 11 through a support arm 13. An air guide 14 is provided between the support arms 13. The airflow is pumped into the fan 1 through the air inlet of the housing 5, then blown out of the air guide 14 from the fan 1, and finally blown out of the air guide 14 to the air outlet of the housing 5.

[0029] The outer casing 5 of this utility model tightly integrates the fan 1, power module 2, circuit board 3, and control module 4, ensuring stable operation of the internal components and facilitating installation and maintenance. The power module 2 provides power to the air pump and can be a battery-equipped power module 2 as shown in the attached diagram, or a plug-in power module 2. The circuit board 3 serves as the core hub for electrical connections, and the control module 4 controls the start and stop of the air pump, ensuring it operates as needed. The innovation of this application lies in the structure related to the duct design; the motor portion of the fan 1, the power module 2, the circuit board 3, and the control module 4 can refer to conventional techniques in the prior art.

[0030] The self-heating principle of this application is as follows: when the air pump is turned on, external airflow is pumped in through the air inlet of the outer casing 5. After being accelerated by the fan body 11, the airflow carrying heat flows towards the cooling fins 12. At this time, the cooling fins 12 will block the airflow, and the airflow changes direction and diffuses in all directions. During the diffusion process, the airflow exchanges heat with the fan 1, carrying away heat and lowering the temperature. Compared with the straight-in-straight-out airflow method in the prior art, this application can prolong the airflow circulation time in the fan 1, thereby increasing the space and time for heat exchange, thus achieving the goal of efficient heat dissipation in a small fan.

[0031] In some embodiments, the outer surface of the fan 1, the support arm 13, and the cooling fins 12 can be made of metals with good thermal conductivity. The efficient heat-conducting metal will quickly conduct heat from the area with higher heat to the area with relatively lower heat, and the airflow will carry away more heat under the same conditions.

[0032] In some embodiments, such as Figure 1-2As shown, the power module 2 is housed inside the handle of the outer casing 5, at least a portion of the circuit board 3 is located at the bottom of the power supply, and the control module 4 is mounted on the handle of the outer casing 5. This layout is quite reasonable, balancing functionality and ergonomics. Firstly, since the handle is the primary point of grip for the air pump, placing the power module 2 here brings the air pump's center of gravity closer to the grip point, reducing hand fatigue during prolonged use. Secondly, the enclosed space of the handle provides physical protection for the power module 2, reducing the impact of external collisions and dust on the power supply and ensuring power stability. Furthermore, the space reserved inside the handle facilitates the removal and replacement of the power module 2, improving the maintainability of the device.

[0033] Circuit board 3 adopts a layered layout, with at least a portion located at the bottom of the power supply. This design effectively utilizes the vertical space inside the air pump. By stacking circuit board 3 and power module 2 vertically, the horizontal space occupied by the traditional flat layout is avoided, making the overall structure of the air pump more compact. Simultaneously, the layered installation method facilitates the zoned management of electrical components, reduces electromagnetic interference between different modules, and improves the stability and reliability of the air pump's electrical system. Furthermore, the proximity of circuit board 3 to power module 2 shortens the power transmission path, reduces line losses, and further improves the energy efficiency of the air pump.

[0034] The control module 4 is mounted on the handle surface of the housing 5, designed for convenient operation and rapid response. When holding the air pump, the user's fingers can naturally reach the buttons or touch areas of the control module 4, allowing for start / stop, mode adjustment, and other operations without changing the grip posture, greatly improving ease of use.

[0035] In some embodiments, at least a portion of the circuit board 3 is integrated onto the cooling plate 12. Since the cooling plate 12 is located at the air outlet, all airflow from the fan 1 will first pass through the cooling plate 12, thus the cooling plate 12 has a good heat dissipation effect. In this case, integrating the heat-generating circuit board 3 or other devices onto the cooling plate 12 can quickly dissipate heat and achieve a better heat dissipation effect.

[0036] In some embodiments, the cooling fin 12 is provided with a cooling fin guide plate 121. When airflow flows out from the air guide port 14 and converges on the side of the cooling fin 12 away from the fan 1, if the cooling fin guide plate 121 is not provided, the opposing airflows will cancel each other out, resulting in a weakening of the airflow. After the cooling fin guide plate 121 is provided, the airflow changes direction at the cooling fin guide plate 121 and achieves convergence in the same direction, thereby avoiding the weakening of the airflow and improving the inflation efficiency.

[0037] In some embodiments, the housing 5 is also provided with a lanyard hole, which can be connected with an external lanyard to make it easier for users to carry the air pump. It also makes it easier for users to place or store the air pump by hanging, thus enriching the ways of carrying and storing it.

[0038] Example 2

[0039] In this embodiment, as Figure 4-5 As shown, it also includes a fan housing 6 outside the fan 1. The fan housing 6 encloses and seals the fan 1 and has a through hole for airflow to enter and exit. The airflow outflow direction of the fan housing 6 is provided with an air-gathering hole 64.

[0040] The fan housing 6 added in this embodiment serves as a dedicated protective and airflow guiding component for the fan 1. By tightly enclosing the fan body 11, it forms an independent airflow circulation space. The through holes on the surface of the fan housing 6 accurately plan the airflow in and out paths. Outside cold air is pumped into the fan 1 through the air inlet, diffuses outwards after passing through the cooling fins 12, exchanges heat with the heat-generating components, carries the heat, and is concentrated and discharged through the air-gathering holes 64, ensuring that the airflow forms an efficient heat dissipation circulation within the fan housing 6. This closed design not only concentrates the diffused airflow to increase the pressure at the output port, allowing for the pumping of higher-pressure gas to the outside, but also effectively isolates the noise generated by the operation of the fan 1, improving the quietness of the air pump operation.

[0041] In some embodiments, the fan housing 6 includes a front cover 61 and a rear cover 62, which fit together and enclose the fan 1. The front cover 61 is provided with a wind deflector 63. The front cover 61 and the rear cover 62 achieve all-around enclosure of the fan through their fit. The mating design of the front and rear covers facilitates the installation, disassembly, and maintenance of the fan, reducing the difficulty of equipment maintenance. At the same time, the sealing structure at the joint of the front and rear covers can prevent dust, moisture, and other impurities from entering the fan, extending the service life of the fan.

[0042] In some embodiments, the air cover guide plate 63 is composed of several air cover guide sub-plates 631, the shoulders of which are stepped, sloping, or arc-shaped. This stepped, sloping, or arc-shaped design significantly optimizes airflow dynamics. Through layering or gradient guidance, the stepped, sloping, or arc-shaped design guides, cuts, and accelerates the airflow, increasing the contact area between the airflow and the cooling fins 12 and improving heat exchange efficiency.

[0043] In some embodiments, the front cover 61 and the rear cover 62 of the fan are provided with matching through holes 65, which are connected and fixed to the outer casing 5. The through holes 65 reserved in the front and rear covers are fixed to the air pump outer casing 5 by bolts or buckles and other connecting parts to ensure a stable connection between the fan casing 6 and the overall structure, and to prevent the components from loosening due to vibration during operation.

[0044] Example 3

[0045] In this embodiment, as Figure 6-7As shown, it also includes an air inflator 7, and the flow-guided self-cooling air pump and the air inflator 7 are provided with a matching docking and fixing structure 8.

[0046] Specifically, in this embodiment, the docking and fixing structure 8 is configured as a slot 81 on the fan housing 6 and a protrusion 82 on the air inflator 7. The protrusion 82 can be rotated and slid into the slot 81 to achieve locking and fixing.

[0047] The slot 81 on the blower housing 6 is equipped with an inclined guide surface and a limiting step. The inclined surface guides the protrusion 82 to be smoothly inserted, while the limiting step forms a mechanical lock after the protrusion 82 is rotated into place. By utilizing the combined effect of the inclined surface friction and the step blocking force, the joint becomes tighter and tighter when subjected to axial tension, effectively resisting the impact of high-pressure airflow during inflation.

[0048] It should also be noted that, in this document, relational terms such as "first" and "second" are used only to distinguish one entity or operation from another, and do not necessarily require or imply any such actual relationship or order between these entities or operations. Furthermore, the terms "comprising," "including," or any other variations thereof are intended to cover non-exclusive inclusion, such that a process, method, article, or apparatus that comprises a list of elements includes not only those elements but also other elements not expressly listed, or elements inherent to such a process, method, article, or apparatus. Without further limitations, an element defined by the phrase "comprising one..." does not exclude the presence of other identical elements in the process, method, article, or apparatus that includes said element.

[0049] The above description of the disclosed embodiments enables those skilled in the art to make or use this application. Various modifications to these embodiments will be readily apparent to those skilled in the art, and the general principles defined herein may be implemented in other embodiments without departing from the spirit or scope of this application. Therefore, this application is not to be limited to the embodiments shown herein, but is to be accorded the widest scope consistent with the principles and novel features disclosed herein.
