Description

Technical Field

[0001] The utility model relates to a fan, and particularly to a fan which not only has a heat dissipation function but also has a drainage structure. Background Art

[0002] With the continuous progress of technology, the vehicle-mounted mobile charging device has advanced from a wired charging mode to a wireless charging mode. In this wireless charging mode, a wireless charging pad is additionally provided under the dashboard in the vehicle. As long as the driver places a mobile device with wireless charging function on the wireless charging pad, the wireless charging pad can quickly charge the mobile device.

[0003] However, the wireless charging pad uses a fast charging mode to charge the mobile device. Therefore, the faster the speed, the easier it is for the wireless charging pad to generate high temperature. In addition, the temperature generated by the operation of other components of the surrounding vehicle body will also indirectly affect the normal operation of the wireless charging pad. Therefore, a heat dissipation fan is installed below the wireless charging pad to dissipate the heat source generated by the wireless charging pad to ensure the normal operation of the wireless charging pad.

[0004] Since the wireless charging pad is installed under the dashboard, it is generally quite close to the drink holder. When the driver or passenger drinks or drinks water in the car and accidentally knocks it over on the wireless charging pad, the liquid of the drink or drinking water is likely to flow into the wireless charging pad, and the flowing liquid will cause faults or damages to the wireless charging pad and the heat dissipation fan.

[0005] Therefore, how to prevent the liquid flowing into the wireless charging pad or the heat dissipation fan from causing faults or damages to the wireless charging pad or the heat dissipation fan is the problem to be solved by this creation. Summary of the Utility Model

[0051] Regarding the technical content and detailed description of the present creation, it is described as follows in conjunction with the drawings:

[0052] Please refer to Figures 1 to 3 , which is the three-dimensional external view schematic diagram of the fan of the first embodiment of the present creation, the exploded schematic diagram of Figure 1 and the top view schematic diagram of Figure 2 . As shown in the figure: The fan with a drainage structure of the present creation, the fan 10 includes: a fan blade group 1 and a drainage structure 2. Among them, the fan 10 is installed below an electronic device (not shown in the figure) for heat dissipation, and can receive the liquid flowing into the electronic device and smoothly discharge the liquid, so as to prevent the fan 10 from being short-circuited or damaged by the inflowing liquid.

[0053] The blade group 1 includes a receiving plate 11 and a blade 12. The blade 12 is assembled on the receiving plate 11. The blade 12 includes a hub 121, a ring 122, and a plurality of blades 123 connected between the hub 121 and the ring 122. A bearing (not shown in the figure) is arranged at the axis of the hub 121 (not shown in the figure), and a control circuit board (not shown in the figure) is arranged between the hub 121 and the receiving plate 11 to control the rotation of the hub 121. A cable group 124 electrically connected to the control circuit board is arranged on the receiving plate 11, and the cable group 124 is used for electrical connection with an external power supply or an electronic device (not shown in the figure). Since the blade group 1 is a conventional technology, only a simple description is given here. In addition, a plurality of fixing holes 111 are arranged on the receiving plate 11, and the fixing holes 111 are used to provide the connection between the receiving plate 11 and the drainage structure 2.

[0054] It is worth mentioning that the receiving plate 11 is a circuit board, and the production of the aforementioned control circuit board can be omitted, and the cable group 124 can be directly electrically connected to the main board 11. When the receiving plate 11 is a plastic plate, it is used to provide the assembly of the blade 12 and the drainage structure 2 together.

[0055] The drainage structure 2 includes a cover 21, a water collecting tank 22, and a plurality of connecting parts 23. An accommodating part 211 and a fixing part 212 located around the accommodating part 211 are arranged inside the cover 21. After the receiving plate 11 is connected to the cover 21, the blade 12 is located in the accommodating part 211. An opening 213 is arranged in the accommodating part 211. In addition to inhaling or discharging air flow during heat dissipation, when the inflowing liquid volume is large, the liquid can be directly discharged through the opening 213. After a plurality of locking pieces (not shown in the figure) 112 pass through the fixing holes 111, they can be locked on the fixing part 212 to assemble the receiving plate 11 and the cover 21 together. In addition, the water collecting tank 22 is connected to one side of the cover 21, the water collecting tank 22 is communicated with the accommodating part 211, a through hole 221 and an arc-shaped guiding part 222 are arranged on the water collecting tank 22, a rib line 223 is arranged on the inner wall surface of the guiding part 222, and a drainage surface 225 with a height gradually decreasing from the rib line 223 to the two side walls 224 and in an arc shape is arranged between the rib line 223 and the two side walls 224 of the guiding part 222. A drainage hole 226 and a guiding inclined surface 227 communicated with the drainage hole 226 are arranged at the connection of the drainage surface 225 and the two side walls 224 to assist the liquid to flow to the drainage hole 226 to discharge the liquid flowing into the water collecting tank 22. In addition, the connecting parts 23 are arranged on the cover 21 and the water collecting tank 22 to provide the installation of the drainage structure 2 below an electronic device (not shown in the figure) for heat dissipation and discharging the inflowing liquid.

[0056] Please refer to Figures 4 to 7 system is in Figure 3Schematic diagram of a sectional view taken along the 4-4 position, system Figure 4 Partial enlarged schematic diagram, system at Figure 3 Schematic diagram of a sectional view taken along the 6-6 position of Figure 6 Partial enlarged schematic diagram, and at the same time, refer to Figures 1 to 3 as well. As shown in the figure: When the fan with a drainage structure of this creation is installed and used, the fan 10 of this creation is installed below an electronic device (not shown in the figure). The electronic device mentioned in this creation is a vehicle-mounted wireless charging device.

[0057] When the vehicle-mounted wireless charging device charges a mobile phone, when the fan blades 12 of the fan 10 rotate, the temperature generated by the wireless charging device can be dissipated to ensure that the wireless charging device can operate normally and will not cause the wireless charging device to malfunction during the charging process.

[0058] When the wireless charging device charges a mobile phone and the user accidentally knocks over drinking water or a beverage in the vehicle, after the liquid flows into the wireless charging device, it will flow into the through-port 221 of the water collecting tank 22 of the drainage structure 2 and pass through the inner wall surface of the guiding portion 222. If the amount of liquid flowing in is large and fast, the liquid directly flows to the opening 213 and is discharged. If the amount of liquid flowing in is small, when flowing through the inner wall surface of the guiding portion 222, it will be drained along the drainage surfaces 225 on both sides of the ridge line 223 to the guiding inclined surface, and then discharged through the drainage hole 226, so as to prevent the liquid from affecting the normal rotation of the fan blades 12 and ensure that the wireless charging device and the fan blades 12 will not be damaged by the liquid.

[0059] However, the above is only the preferred embodiment of this creation and is not intended to limit the patent protection scope of this creation. Therefore, all equivalent changes made by using the content of the specification or drawings of this creation are equally included in the scope of the rights protection of this creation, and this is hereby stated.
