If there is a description of "first" or "second," it is only for the purpose of distinguishing technical features and should not be construed as indicating or implying relative importance or implicitly indicating the number of indicated technical features or the order of the indicated technical features.

[0025] In the description of this utility model, unless otherwise explicitly defined, terms such as "setting," "installation," and "connection" should be interpreted broadly, and those skilled in the art can reasonably determine the specific meaning of the above terms in this utility model in conjunction with the specific content of the technical solution.

[0026] like Figures 1 to 7As shown, this utility model discloses a wireless power bank with a cooling function, including a housing 11, a wireless charging component, a heat dissipation component, and a power supply component. The housing 11 includes a first accommodating space and a second accommodating space. The wireless charging component and the heat dissipation component are both disposed in the first accommodating space, and the power supply component is disposed in the second accommodating space. Since both the power supply component and the wireless charging component generate heat during operation, heat can be separated and excessive heat concentration can be prevented by distributing them in the first and second accommodating spaces respectively. The wireless charging component includes a coil assembly 21 that is attached to the inner wall of the upper end of the housing 11. The heat dissipation component includes a semiconductor cooling chip 31, a heat sink 32, and a turbine fan 33. The thermoelectric cooler 31 is attached to the coil assembly 21 and the heat sink 32 on both sides, respectively. The turbine fan 33 is located on one side of the heat sink 32. The cold end of the thermoelectric cooler 31 is attached to the coil assembly 21, which can effectively cool the coil assembly 21. The heat sink 32 can dissipate heat from the thermoelectric cooler 31, and the turbine fan 33 can dissipate heat from the heat sink 32, so that it has a better and faster heat dissipation effect. The housing 11 has an air inlet 12 at one end near the turbine fan 33 and an air outlet 13 at one end near the heat sink 32. After the air enters through the air inlet 12, it is blown to the heat sink 32 by the turbine fan 33, and then the hot air generated after flowing through the heat sink 32 is discharged from the air outlet 13.

[0027] This invention achieves effective heat dissipation of the coil assembly 21 by setting a semiconductor cooling chip 31 that is attached to the coil assembly 21, and heats the semiconductor cooling chip 31 by using a heat sink 32 and a turbine fan 33, which greatly reduces the temperature of the power bank during operation, ensuring the normal operation of the power bank. In addition, it can also remove some of the heat generated when the mobile phone is wirelessly charged, thus improving the user experience.

[0028] In this utility model, the power supply assembly includes a circuit board 41 and a battery 42 electrically connected to the circuit board 41. The battery 42 is located at one end near the heat sink 32, and the circuit board 41 is located at one end near the turbine fan 33. A heat dissipation partition 51 is provided between the heat sink 32 and the battery 42. The two sides of the heat dissipation partition 51 are respectively attached to the heat sink 32 and the battery 42. In this way, some of the heat generated by the battery 42 can be conducted to the heat sink 32 through the heat dissipation partition 51 and dissipated by the heat sink 32. The coil assembly 21, the semiconductor cooling chip 31 and the turbine fan 33 are all electrically connected to the circuit board 41.

[0029] In this utility model, the heat dissipation partition 51 is provided with a connecting hole 52 at one end near the turbine fan 33 for connecting the air outlet 13 and the turbine fan 33, so that air enters from the air outlet 13, passes through the lower end of the heat dissipation partition 51 and then flows into the turbine fan 33 through the connecting hole 52. This can dissipate heat from the circuit board 41 at the lower end of the heat dissipation partition 51, thereby improving the overall heat dissipation effect of the power bank.

[0030] In this utility model, the air inlet end of the turbine fan 33, the connecting hole 52 and the air inlet hole 12 form an air inlet channel, and the air outlet end of the turbine fan 33, the radiator 32 and the air outlet hole 13 form an air outlet channel.

[0031] In this utility model, the housing 11 is also provided with a charging interface 43, an indicator light 44 and a control button 45 that are electrically connected to the circuit board 41, so as to realize the functions of charging, power display and switching operation of the power bank.

[0032] In this utility model, a fan fixing bracket 61 is also provided inside the housing 11, and the turbine fan 33 is fixed in the first accommodating space by the fan fixing bracket 61.

[0033] In this utility model, the housing 11 includes an upper housing 111 and a lower housing 112 detachably connected to the upper housing 111. The heat dissipation baffle 51 is connected to the upper housing 111 by screws. This layout is more reasonable and convenient for assembly.

[0034] In this utility model, both the air inlet 12 and the air outlet 13 are strip-shaped holes to ensure the air intake and exhaust effects. The air inlet 12 is provided with a mesh baffle 14 to prevent foreign objects from entering.

[0035] In this utility model, the heat sink 32 is provided with a cooling chip receiving groove, and the semiconductor cooling chip 31 is installed in the cooling chip receiving groove to realize the limiting and fixing of the semiconductor cooling chip 31.

[0036] In this invention, the wireless power bank also includes a support plate 71. A support storage groove 72 is provided on the outer side of the lower end of the housing 11. The support plate 71 can be stored within the support storage groove 72, and one end of the support plate 71 is hinged to one end within the support storage groove 72. When the support plate 71 is opened, the power bank can be supported, meeting different user needs.

[0037] This invention achieves effective heat dissipation of the power bank through a heat dissipation component, resulting in better heat dissipation. Furthermore, by setting up a first and a second accommodating space, it ensures that the heat from the power bank does not concentrate excessively during operation, guaranteeing rapid heat dissipation at the charging coil and also removing some of the heat generated during mobile phone charging, greatly improving the user experience.

[0038] The above description, in conjunction with specific preferred embodiments, provides a further detailed explanation of the present invention. It should not be construed that the specific implementation of the present invention is limited to these descriptions. For those skilled in the art, various simple deductions or substitutions can be made without departing from the concept of the present invention, and all such modifications and substitutions should be considered within the protection scope of the present invention.
