[0034] In order to make the purpose, technical solution and advantages of the embodiments of the present application clearer, the technical solution in the embodiments of the present application will be clearly and completely described below in conjunction with the drawings in the embodiments of the present application. Obviously, the described embodiments are part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of this application.

[0035] At present, common cooling fans absorb heat through water evaporation to achieve the purpose of blowing out cold air. Installing a wet curtain on the cooling fan can not only increase the heat exchange area, but also prevent the water flowing down the water distribution structure from being sucked into the fan. However, there are two types of wet curtain structures of existing cooling fans: one is that there is no missing protection device. If the fan is started without installing a wet curtain, the water droplets sprayed by the water spray device of the cooling fan will directly drip to the bottom of the cooling fan, and the splashing water may be sucked into the fan, posing an electrical safety hazard. Based on this, Figure 1 As shown, the present application provides a water spray control device for a cooling fan, comprising: a housing 10, a toggle member 20 and a water blocking member 30;

[0036] The housing 10 is provided with a top water outlet 12, and a top connecting member 11 is provided below the top water outlet 12; the rotating shaft of the toggle member 20 is movably connected to the top connecting member 11, the oblique guide portion of the toggle member 20 is provided above the wet curtain, and a connecting portion is provided on the rotating shaft, and the connecting portion is movably connected to the water blocking member 30, and the end of the connecting portion of the toggle member 20 and the water blocking portion of the water blocking member 30 slide along the gap between the top connecting member 11 and the housing 10;

[0037] In the embodiment of the present application, the shell 10 refers to the outer shell of the water spray control device of the cold fan, and is not limited to the part marked in the figure. The top water outlet 12 on the shell 10 can be used to connect to the water spray device on the cold air fan. The water spray device sprays water droplets through the top water outlet 12. Using the principle of heat exchange, the water droplets evaporate when heated and take away the heat, so that the fan draws in cold air and blows it out.

[0038] In the embodiment of the present application, a top connecting member 11 is arranged below the top water outlet 12, and the top connecting member 11 is movably connected to the rotating shaft of the toggle member 20 for fixing the position of the rotating shaft. Preferably, the top connecting member 11 can be an axis hole so that the rotating shaft of the toggle member 20 can be movably connected to the axis hole. In addition, the top connecting member 11 can also be a structure such as a slot that can be movably connected to the rotating shaft of the toggle member 20. The specific setting can be determined according to actual conditions.

[0039] In the embodiments of the present application, Figure 2 As shown, the oblique guide portion 21 of the toggle member can rotate with the rotating shaft 22 as the center, and a connecting portion 23 is provided on the rotating shaft 22, and the connecting portion 23 is used to be movably connected with the water blocking member, and the end of the connecting portion 23 of the toggle member and the water blocking portion of the water blocking member slide along the gap between the top connecting member and the shell.

[0040] In actual applications, a connecting portion is provided on the rotating shaft, and the connecting portion is movably connected to the water-blocking member. Preferably, a plurality of axial holes are provided on the connecting portion of the rotating shaft, and a connecting shaft is provided on the water-blocking member, and the rotating shaft is movably connected to the connecting shaft of the water-blocking member through the plurality of axial holes. In addition, the connecting portion may also be a hinged shaft, and accordingly, an axial hole is provided on the water-blocking member, and the connecting portion and the water-blocking member are movably connected through the hinged shaft and the axial hole. The embodiments of the present application are only for enumeration, and the specific settings may be determined according to actual conditions.

[0041] In which, the inclined guide portion of the toggle member is arranged above the wet curtain. In the embodiment provided in the present application, when the wet curtain of the cold fan is not assembled, preferably, the first end of the inclined guide portion is connected to the rotating shaft; when the second end of the inclined guide portion naturally droops, the first end of the inclined guide portion drives the rotating shaft to rotate, and the rotating shaft drives the water blocking member to move toward the side of the inclined guide portion, so that the water blocking member is displaced to below the top water outlet of the shell to block the top water outlet.

[0042] like Figure 3 As shown, the top water outlet 12 is arranged near the side of the oblique guide part. When the wet curtain is not installed, the oblique guide part naturally sags due to gravity, and at this time, the rotating shaft connected to the first end of the oblique guide part is driven to rotate in the counterclockwise direction (as shown by the arrow in the figure), and the rotating shaft drives the water blocking member 30 to move near the oblique guide part, so that the water blocking member 30 is displaced to the bottom of the top water outlet 12 of the housing 10, and the top water outlet 12 is blocked. By setting the toggle member 20, the water blocking member 30 is controlled to slide in the horizontal direction according to the installation situation of the wet curtain, so as to achieve the purpose of opening or closing the top water outlet 12.

[0043] The inclined guide portion naturally droops due to the action of gravity, and drives the water blocking member 30 to move to the bottom of the top water outlet 12 of the shell 10 through the rotating shaft to block the top water outlet 12. When the wet curtain of the cooling fan is not installed, the top water outlet 12 is blocked to prevent water droplets from falling to the bottom of the shell 10 and causing splashing water, thereby avoiding electrical safety problems caused by the fan sucking in the splashing water.

[0044] In addition, when the wet curtain of the cold fan is assembled, the wet curtain can lift up the toggle member, and the inclined guide portion drives the water blocking member to move in a direction away from the top water outlet through the rotating shaft, and water can flow out normally from the top water outlet. Preferably, when the wet curtain is assembled, the water blocking member cannot be arranged below the top water outlet to prevent water droplets from falling onto the water blocking member.

[0045] In another embodiment provided in the present application, Figure 4 As shown, the water spray control device of the cooling fan further includes: a dustproof net 40;

[0046] The dustproof net 40 is arranged at one side of the wet curtain, and the protruding ribs 41 on the dustproof net 40 are arranged above the wet curtain, so that when the wet curtain is assembled, the protruding ribs 41 lift up the oblique guide part.

[0047] In the embodiment of the present application, a dustproof net 40 for dust prevention may be further installed on the wet curtain of the cooling fan, and a protruding rib 41 is provided on the dustproof net 40, and the protruding rib 41 is arranged above the wet curtain.

[0048] like Figure 5 As shown, in actual application, when the wet curtain is assembled, the protruding rib 41 can lift the toggle member, so that the toggle member drives the rotating shaft, and the rotating shaft drives the water blocking member away from the top water outlet. The specific working process can refer to the above, and the working process of installing the wet curtain to lift the toggle member will not be repeated here.

[0049] In another embodiment provided by the present application, a cooling fan is further provided, comprising: a water spray control device for the cooling fan described in any one of the above embodiments;

[0050] In the embodiment of the present application, the water spray control device is arranged in the air inlet area of ​​the cold fan so that when the wet curtain of the cold fan is not installed, the water droplets sprayed above the cold fan will not fall on the inner bottom plate of the cold fan, thereby avoiding splashing water and being sucked into the fan, causing damage to the appliance.

[0051] In another embodiment provided by the present application, the cooling fan further comprises: a top cover and a water spray device;

[0052] The water spray device is arranged in the cavity inside the top cover and above the air inlet area of ​​the cooling fan;

[0053] The top cover is arranged on the top of the shell, and the water outlet of the water spraying device is arranged above the top water outlet of the shell for spraying water droplets downward.

[0054] In an embodiment of the present application, a top cover is arranged on the top of the shell, and a water spray device is arranged in the cavity inside the top cover, wherein the water outlet of the water spray device can be arranged above the air inlet area of ​​the cooling fan to spray water droplets downward. By utilizing the principle of heat exchange, the water droplets evaporate when heated and take away the heat, so that the fan inhales cold air and blows it out.

[0055] In an embodiment of the present application, a shell of a water spray control device is arranged inside a cooling fan, an air inlet area of ​​the shell and an air inlet area of ​​the cooling fan are arranged on the same side, and a connecting piece may also be arranged on the air inlet side of the shell for connecting a wet curtain of the cooling fan. When the wet curtain of the cooling fan is assembled, the wet curtain can lift up the toggle piece, and the oblique guide portion drives the water blocking piece to move in a direction away from the top water outlet through the rotating shaft, so that water can be discharged normally at the top water outlet, and water droplets can drip onto the wet curtain, which increases the cold and heat exchange area while protecting the electrical appliance from being sucked into the fan after splashing. When the wet curtain of the cooling fan is not assembled, the oblique guide portion naturally droops under the action of gravity, and drives the water blocking piece to move to the bottom of the top water outlet of the shell through the rotating shaft, blocking the top water outlet, so as to block the top water outlet when the wet curtain of the cooling fan is not installed, preventing water droplets from falling to the bottom of the shell to cause water splashing, and avoiding electrical appliance safety problems caused by the fan sucking in water splashes.

[0056] Optionally, in an embodiment of the present application, a water-absorbing sponge is provided on the bottom inner surface of the shell, which can absorb moisture when water overflows from the drainage groove or water droplets sprayed by the water spraying device fall, and can achieve the purpose of preventing water splashing, thereby ensuring the safe operation of the appliance.

[0057] In another embodiment of the present application, Figure 6 As shown, the top cover 50 is provided with a drain port 51, which is used to drain water from the drain port 51 when the water blocking member blocks the water outlet 52 of the water spraying device. Correspondingly, the air cooler further comprises: a water tank; the water inlet of the water tank is connected to the drain port 51 of the top cover 50, and stores water discharged from the drain port 51 of the top cover 50.

[0058] The water tank is used to store the water drained by the drainage trough. Since the drainage trough can drain the collected water to a lower place by gravity, the water tank can preferably be arranged at the bottom of the shell.

[0059] It should be noted that, in this article, relational terms such as "first" and "second" are only used to distinguish one entity or operation from another entity or operation, and do not necessarily require or imply any such actual relationship or order between these entities or operations. Moreover, the terms "include", "comprise" or any other variants thereof are intended to cover non-exclusive inclusion, so that a process, method, article or device including a series of elements includes not only those elements, but also other elements not explicitly listed, or also includes elements inherent to such process, method, article or device.
