Description

Technical Field

[0001] The present application relates to the technical field of cooling devices, and in particular to a cooling fan anti-splash device and a cooling fan. Background Art

[0002] A cooling fan is an evaporative cooling device between a fan and an air conditioner, which usually includes a water tank, a water pump, a wet curtain and a fan. Its working principle is: the water pump extracts water from the water tank and transports it to the wet curtain to form a water film; the external airflow is sucked in at high speed under the action of the fan, so that the water on the water film quickly evaporates from liquid to gas to absorb the heat in the airflow, and the cold air is sent out at high speed through the air guide port to achieve the cooling function. Some cooling fans also enhance the heat absorption effect by adding refrigerants such as "ice crystals" to the water. Other cooling fans have functions such as air purification and sterilization. Because cooling fans are more flexible than traditional air conditioners, have lower power consumption, are more affordable, and have better cooling effects than traditional fans, they have a larger market demand.

[0003] Most existing cooling fans use a wet curtain structure, which plays the role of dispersing water flow. When the wet curtain is not installed, the circulating water in the fan will fall directly from a high place and splash, affecting the user experience. If the splashing water enters the internal electrical components of the cooling fan, it will cause greater harm. Summary of the invention

[0004] In order to solve the above technical problems, the cooling fan wet curtain is prevented from causing the return water in the fan to splash from a high place and splash out of the cooling fan, affecting the user experience or splashing into electrical components, causing safety hazards.

[0027] In the embodiment of the present application, a drainage groove 1 is mainly added to the lower part of the top water tank 101 of the cooling fan 10, and the drainage groove 1 can guide the water flowing down in the water tank 101 to the water tank 103 at the bottom of the fan; a reset member 2 is added to the drainage groove 1, and when the wet curtain is installed in the cooling fan 10, the drainage groove 1 will be retracted under the push of the wet curtain 5; when the wet curtain 5 is not installed in the cooling fan, the drainage groove 1 will pop up under the action of the reset member 2, and the water flowing down in the top water tank 101 will be drained to the bottom water tank 103. A drawer-type pop-up drainage groove 1 is added under the top water tank 101 of the cooling fan to drain the return water. Under the action of the reset member 2, the drainage groove 1 pops up to drain the return water, and is pressed back to the drainage groove 1 after the wet curtain 5 is installed. Through the action of the drainage groove 1, when the wet curtain 5 is not installed, the return water in the fan will not splash directly from a high place.

[0028] In the embodiment of the present application, as shown in the figure, the drainage trough 1 mainly includes a drainage plate 11, a bottom plate 12, a side plate 13 and a confluence nozzle 14. The drainage plate 11, the bottom plate 12 and the side plate 13 form a container, and the drainage plate 11 is tilted to facilitate the diversion of falling water into the container. The drainage plate 11 can collect leaking water corresponding to the water supply port 6; and the confluence nozzle 14 is arranged on one side of the container of the drainage trough 1 and connected to the lower water container of the cooling fan. In the embodiment of the present application, the confluence nozzle 14 is located on one side of the drainage plate 11, and the confluence nozzle 14 is obliquely connected downward to the downward diversion guide plate 46.

[0029] In the embodiment of the present application, the drainage groove 1 has sliding guides 31 on both sides, and the sliding guides 31 are selected to be horizontal grooves formed on the side walls of the housing, so that the drainage groove 1 can be horizontally guided on both sides. The corresponding cooling fan housing is provided with corresponding sliding limit parts 15, and the sliding limit parts 15 are selected to be convex columns on both sides of the drainage groove 1, and the convex columns extend into the guide grooves to guide the drainage groove 1 to slide between the retracted position and the splash-proof drainage position.

[0030] In the embodiment of the present application, the reset mechanism 2 includes an energy storage member 21 and a guide column 22, and a corresponding limiting hole 45 is arranged on the cooling fan housing, so that the energy storage member 21 pushes the drainage groove 1 to slide from the stowed position to the splash-proof drainage position.

[0031] In the embodiment of the present application, a water guiding structure is further provided outside the guide plate 46 to guide water to the lower water container. The water guiding structure may be a drop-in channel disposed in the rear shell cavity, and a drop-in port leading to the bottom water tank 102 may be disposed below the drop-in channel. When water drops into the guide plate, the water will flow from the confluence nozzle on the guide plate to the guide plate on the rear shell cavity, and then flow to the rear shell partition cavity, which has a notch, and the water will flow down from the notch back to the bottom water tank.

[0032] The water guiding structure may also include a water collecting box 41 . The water collecting box 41 is further provided with a water collecting area 42 corresponding to the guide plate 46 . The water collecting area 42 may be connected to a water pipe to convey the falling water to the bottom water tank 102 .

[0033] Figure 3 A schematic diagram of the cooling fan assembly structure provided in the embodiment of the present application, and Figure 4 A schematic diagram of the installation of the drainage groove of the cooling fan provided in the embodiment of the present application. On the other hand, the embodiment of the present application provides a cooling fan, including the cooling fan anti-splash device as described above, the cooling fan includes a wet curtain installation position, the anti-splash drainage position of the drainage groove 1 is located in the wet curtain installation position, and when the wet curtain 5 is installed in the wet curtain installation position, the drainage groove 1 is pushed to the retracted position.

[0034] In the embodiment of the present application, the cooling fan has a bottom water tank 102, and a water pump 103 is arranged inside the water tank. The water pump 103 pumps water from the bottom water tank 102 to the top water tank 101. The water tank 102 has a row of water flow holes 6 facing the wet curtain installation position.

[0035] When the wet curtain is installed in the cooling fan, Figure 5 As shown, at this time, the wet curtain will press the drainage plate back into the rear shell cavity, and the water in the top water tank will flow to the wet curtain and moisten the wet curtain; when the wet curtain is taken out, the drainage plate will pop out under the action of the spring force. Due to the restrictions of the card slot and the guide plate, the inclined surface of the drainage plate will be aligned with the water flow hole of the top water tank. The inclined surface can reduce the sound of dripping water and avoid splashing of water. At this time, the water flowing down from the top water tank will drip into the drainage plate and return to the bottom water tank under the action of the drainage plate, thereby preventing the problem caused by the wet curtain being missed and the water splashing from a high place.
