[0002] Miniature brushless ducted fans are small, portable electric fans that generate airflow through a motor. They are mainly used for personal cooling or ventilation in small spaces. To extend the lifespan of miniature brushless ducted fans and prevent damage caused by excessive heat on the internal walls, miniature brushless ducted fans with heat dissipation capabilities are needed. The "A Portable and Disassembleable Miniature Cooling Fan" disclosed in application number "CN201821184113.1" is an increasingly mature technology. This portable and disassembleable miniature cooling fan features a simple structure, is readily available for use, provides heat dissipation for internal components anytime and anywhere, is safe and reliable, and is easy to disassemble. The fan blades are designed in an axial flow shape, and when rotating, because the fan... The axial flow shape of the blades concentrates the airflow, optimizing heat dissipation and enabling faster cooling of the machine's internal components. The fan blades are fixed to the shaft using bolts, ensuring a tighter connection during operation. However, this miniature fan has the following drawbacks: while the processor and heatsink do provide cooling, the effect is insufficient, requiring additional heatsinks and increasing costs. Therefore, a miniature brushless ducted fan that enhances cooling without requiring additional cooling mechanisms is necessary. Utility Model Content

[0003] The present invention provides a miniature brushless ducted fan that facilitates heat dissipation, aiming to solve the problem that the heat dissipation effect of existing miniature fans is not significant enough.

[0004] To achieve the above objectives, this utility model provides a miniature brushless ducted fan that facilitates heat dissipation, including a fan assembly;

[0005] The fan assembly includes a housing with a mounting port at the lower end. The housing has a square structure and an upper air outlet at the upper end. A turbine fan is installed inside the housing. A bottom mounting plate is installed inside the mounting port, and several bottom air inlets are provided on the surface of the bottom mounting plate.

[0006] As a preferred embodiment of this utility model, a control circuit board is embedded inside the outer casing.

[0007] As a preferred embodiment of this utility model, the surface of the control circuit board is respectively equipped with a type-C interface and a control switch.

[0008] In a preferred embodiment of this utility model, the control circuit board is electrically connected to the type-c interface and the control switch respectively.

[0009] As a preferred embodiment of this utility model, a storage battery is installed at the lower end of the turbine fan inside the outer casing.

[0010] As a preferred embodiment of this utility model, the upper air outlet, the turbine fan, and the bottom air inlet are adapted to each other.

[0011] In a preferred embodiment of this utility model, the outer shell is cylindrical, the bottom mounting plate and the bottom air inlet are both circular, and the control circuit board, the Type-C interface and the control switch are located at the bottom of the outer shell.

[0012] Compared with the prior art, the beneficial effects of this utility model are:

[0013] 1. When the miniature brushless ducted fan is started, the control switch on the control circuit board controls the battery to power the turbine fan. The turbine fan rotates, drawing in cool air from outside through several bottom air inlets on the bottom mounting plate of the outer casing. The air is then exhausted through the top air outlet on the outer casing. During this process, the cool air mixes with the heat inside the miniature brushless ducted fan, resulting in a cooling effect. The heat is then expelled, thus performing heat dissipation. This miniature brushless ducted fan has a simple straight-through structure, which reduces the airflow path. The bottom air inlet effectively reduces wind noise and increases airflow speed, thereby improving heat dissipation. Compared to the miniature fan in the existing technology "A Miniature Cooling Fan that is Easy to Carry and Disassemble", this invention, through the combination of the above structures, can perform rapid heat dissipation without the use of additional heat-conducting plates or other structures, thereby reducing cost and improving heat dissipation efficiency.

[0024] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0025] Example 1

[0026] Please see Figures 1-8 This utility model provides a miniature brushless ducted fan that facilitates heat dissipation, including a fan assembly 100;

[0027] The fan assembly 100 includes a housing 101, which is a square structure. The lower end of the housing 101 has a mounting port 102, and the upper end of the housing 101 has an upper air outlet 103. A turbine fan 104 is installed inside the housing 101. A bottom mounting plate 105 is installed inside the mounting port 102, and a plurality of bottom air inlets 106 are opened on the surface of the bottom mounting plate 105.

[0028] In one specific embodiment, the upper air outlet 103 of the fan assembly 100, in conjunction with the turbine fan 104 and the bottom air inlet 106, enables direct-flow heat dissipation without the need for additional heat-conducting structures. This significantly improves the heat dissipation effect of the miniature brushless ducted fan, thereby enhancing its practicality. In use, the control switch 122 is first turned on, allowing the battery 131 to supply power to the turbine fan 104. The rotation of the turbine fan 104 then draws cool air from outside through several bottom air inlets 106 on the surface of the bottom mounting plate 105 at the lower end of the housing 101. The air is drawn into the housing 101 and then discharged through the upper air outlet 103 on the housing 101. During this process, the cool air from the outside mixes with the heat inside the miniature brushless ducted fan to perform heat exchange, thereby achieving a cooling effect. At the same time, the cool air expels the heat from the housing 101, thus achieving heat dissipation. Through the cooperation of the above structures, heat dissipation can be achieved without the use of additional heat dissipation structures. This not only improves heat dissipation efficiency, but also effectively reduces wind noise and increases airflow speed by bottom air intake, while also reducing cost losses. Therefore, it enhances the practicality of the miniature brushless ducted fan.

[0029] Please see Figure 2 A control circuit board 111 is embedded inside the outer casing 101.

[0030] In one specific embodiment, the control circuit board 111 facilitates the control of the opening and closing of the miniature brushless ducted fan, thereby improving the ease of use of the automatic control of the miniature brushless ducted fan.

[0031] Please see Figure 2 and Figure 6 The control circuit board 111 has a type-c interface 121 and a control switch 122 mounted on its surface, and the control circuit board 111, type-c interface 121 and control switch 122 are mounted on one side of the housing 101.

[0032] In one specific embodiment, the Type-C interface 121 facilitates connection to a power cord, thereby charging the battery 131 through the Type-C interface 121. The control switch 122, in conjunction with the control circuit board 111, facilitates automatic control of the micro brushless ducted fan's start and stop, improving the ease of use of the micro brushless ducted fan.

[0033] Please see Figure 2 and Figure 6 The control circuit board 111 is electrically connected to the type-c interface 121 and the control switch 122, respectively.

[0034] In one specific embodiment, the convenience of automatic switching of the micro switch can be improved by electrically connecting the control circuit board 111 with the type-c interface 121 and the control switch 122.

[0035] Please see Figures 2-4 A battery 131 is installed at the lower end of the turbine fan 104 inside the outer casing 101.

[0036] In one specific embodiment, the battery 131 facilitates power supply to the miniature brushless ducted fan, making it easy for the miniature brushless ducted fan to be carried and used.

[0037] Please see Figures 2-8 The upper air outlet 103, the turbine fan 104, and the bottom air inlet 106 are compatible.

[0038] In one specific embodiment, the upper air outlet 103, the turbine fan 104, and the bottom air inlet 106 are adapted to shorten the flow path of the cold air and further improve the heat dissipation efficiency of the miniature brushless ducted fan.

[0039] Example 2

[0040] The difference between this embodiment and Embodiment 1 is as follows: Please refer to... Figure 9 A miniature brushless ducted fan for easy heat dissipation includes a housing 101, wherein the housing 101 is cylindrical, the bottom mounting plate 105 and the bottom air inlet 106 are both circular, and the control circuit board 111, the type-c interface 121 and the control switch 122 are located at the bottom of the housing 101.

[0041] In one specific embodiment, the control circuit board 111, type-c interface 121 and control switch 122 located at the bottom of the housing 101 facilitate the charging and control of the micro brushless ducted fan, improving portability and ease of use. At the same time, the cylindrical structure of the housing 101 makes it easy to hold and use.

[0042] Working principle: When in use, first turn on the control switch 122 to control the battery 131 to supply power to the turbine fan 104. The turbine fan 104 rotates, thereby drawing in cool air from the outside through several bottom air inlets 106 on the surface of the bottom mounting plate 105 at the lower end of the housing 101. Then, it is discharged through the top air outlet 103 on the housing 101. During this process, the cool air from the outside mixes with the heat inside the miniature brushless ducted fan to perform heat exchange, thereby achieving a cooling effect. At the same time, the cool air expels heat from inside the housing 101. The bottom air inlet can effectively reduce wind noise, lower noise, and increase wind speed, thereby achieving heat dissipation and enhancing the practicality of the miniature brushless ducted fan.
