[0001] The present invention relates to the field of household appliances, and in particular to a protective structure, a shell and a cooling fan. Background Art

[0002] In the hot summer, in addition to air conditioning, people begin to use various fans to relieve heat and cool down. Among them, evaporative cooling fans have the functions of cooling and humidifying compared with traditional fans, and are becoming more and more popular. In order to achieve the function of blowing out cold air and cooling, there will be a wet curtain at the air inlet to absorb water, increase the contact area between water and air, and thus increase the evaporation amount of the machine, and drip water from the top of the wet curtain to moisten it. Because the wet curtain is a detachable and replaceable component, there may be cases where users forget to install the wet curtain. If the wet curtain is missed, water will drip directly when the cooling fan is working, abnormal noise will occur, or water will be sucked into the machine and sprayed out from the air outlet, affecting the user's comfort and posing an electrical safety hazard. Summary of the invention

[0003] The object of the present invention is to provide a protective structure, a housing and a cooling fan, which can solve the problems of noise, water splashing and electrical hazards caused by the leakage of the wet curtain.

[0004] The embodiment of the present invention is achieved as follows:

[0005] A protective structure includes a water receiving structure and a drainage structure installed on a cooling fan housing;

[0006] The water receiving structure is rotatably installed below the water leakage hole of the cooling fan. The water receiving structure can be rotatably opened to receive water drops dripping from the water leakage hole. The drainage structure is longitudinally extended on the shell and guides the water collected by the water receiving structure to flow to the water tank below the cooling fan.

[0007] Furthermore, in an embodiment of the present invention, the water receiving structure includes a water receiving trough.

[0008] Furthermore, in an embodiment of the present invention, two opposite sides of the water receiving trough are respectively provided with rotating shafts for rotating with the shell.

[0009] Furthermore, in an embodiment of the present invention, a side of the water receiving trough for cooperating with the shell is provided with an elastic structure to facilitate the installation of the water receiving trough.

[0010] Furthermore, in an embodiment of the present invention, the water receiving structure also includes an elastic member for rotating and opening the water receiving trough, one end of the elastic member in the elastic direction is connected to the water receiving trough, and the other end of the elastic member in the elastic direction is used for connection with the shell.

[0011] Furthermore, in an embodiment of the present invention, a water outlet is provided on a side of the water receiving trough facing the drainage structure.

[0012] Furthermore, in an embodiment of the present invention, the drainage structure is a groove-shaped structure.

[0013] A shell comprises the above-mentioned protective structure.

[0014] Furthermore, in an embodiment of the present invention, the shell is provided with a limit block for limiting the rotation angle of the water receiving structure.

[0015] A cooling fan comprises the above-mentioned protective structure.

[0016] The beneficial effects of the embodiments of the present invention are:

[0017] The water receiving structure is rotatably installed under the water leakage hole of the cooling fan, and the water receiving structure can be rotatably opened to receive water drops dripping from the water leakage hole. The drainage structure is longitudinally extended on the shell and guides the water collected by the water receiving structure to flow to the water tank under the cooling fan. When the wet curtain is installed, the wet curtain squeezes the water receiving structure, and the water receiving structure is rotated and closed, and the water flowing out of the water leakage hole falls on the wet curtain, thereby ensuring the cooling function of the cooling fan. When the wet curtain is not installed, the water receiving structure is rotated and opened to receive water drops dripping from the water leakage hole, and the drainage structure guides the water collected by the water receiving structure to flow to the water tank at the bottom of the cooling fan. When the cooling fan is used without the wet curtain installed, water is prevented from flowing to the fan motor and fan, thereby solving the problems of fan splashing and noise, ensuring the proper use of the fan blowing function, and improving the electrical safety of the cooling fan.

[0035] refer to Figure 2 As shown, the protective structure 200 includes a water receiving structure 210 and a drainage structure 220, wherein the water receiving structure 210 is rotatably installed below the water leakage hole of the cooling fan, and the housing 100 is provided with fixing holes 120 for connecting with the water receiving structure 210 on opposite sides. Figure 2The water receiving structure 210 receives the water drops dripping from the water leakage hole, and the drainage structure 220 is located at the inner side of the water receiving structure 210 and is longitudinally extended to the shell 100, and the drainage structure 220 guides the water collected by the water receiving structure 210 to flow to the water tank below the cooling fan; after the wet curtain 500 is installed, the wet curtain 500 squeezes the water receiving structure 210, the water receiving structure 210 rotates and closes, and the water flowing out of the water leakage hole falls on the wet curtain 500, ensuring the cooling function of the cooling fan; when the wet curtain 500 is not installed, the water receiving structure 210 rotates and opens, and the water receiving structure 210 receives the water drops dripping from the water leakage hole, and the drainage structure 220 guides the water collected by the water receiving structure 210 to flow to the water tank at the bottom of the cooling fan. When the cooling fan is used without the wet curtain 500 installed, water can be prevented from flowing to the fan motor fan, and the fan splashing and dripping noise can be avoided, thereby ensuring the correct use of the fan blowing function and improving the electrical safety of the cooling fan.

[0036] refer to Figure 3 As shown, the water receiving structure 210 includes a water receiving trough 211, and a rotating shaft 212 for rotating with the shell 100 is arranged on two opposite sides of the water receiving trough 211. The water receiving trough 211 is provided with an elastic structure 213 on both sides or one side of the rotating shaft 212. That is, the root of the rotating shaft 212 is the elastic structure 213. The rotating shaft 212 is installed in the fixing hole 120 of the shell 100 by squeezing the rotating shaft 212. The elastic structure 213 facilitates the installation of the water receiving trough 211 and can improve the stability of the water receiving trough 211. The water receiving trough 211 is provided with a water outlet 214 corresponding to the drainage structure 220. The water collected by the water receiving trough 211 flows from the water outlet 214 to the drainage structure 220. The drainage structure 220 guides the water to flow to the water tank below the cooling fan. In order to facilitate the opening and closing rotation of the water receiving trough 211, the water receiving structure 210 also includes an elastic member 215. One end of the elastic member 215 in the elastic direction is connected to the water receiving trough 211, and the other end of the elastic member 215 in the elastic direction is connected to the housing 100. When the elastic member 215 is not subjected to external force, the elastic member 215 applies elastic force to the water receiving trough 211, the water receiving trough 211 is in an open state, and the water receiving trough 211 partially extends into the installation area of ​​the wet curtain 500 to ensure that the water from the leaking hole falls to the water receiving trough 211. When the wet curtain 500 is installed, the wet curtain 500 squeezes the water receiving trough 211 out of the installation area, the water receiving trough 211 rotates and retracts, and the elastic member 215 is in a compressed state. The water receiving trough 211 is provided with a mounting hole 215 for connecting with the elastic member 215. In this solution, the elastic member 215 can be a torsion spring or a common spring. When the water receiving trough 211 is retracted, a torsional force and a squeezing force are applied to the elastic member 215.

[0037] In this solution, the elastic structure 213 can be composed of an elastic material, or a plastic with a certain toughness, or can also be composed of a mechanical elastic structure, such as a water receiving trough side structure formed by a spring and a side plate.

[0038] Figure 5 It is a schematic diagram of the state of the water receiving trough 211 when the housing 100 is not installed with the wet curtain 500. The housing 100 is installed with a limit block 110 above the water receiving trough 211. The water receiving trough 211 is rotated and opened by the force applied by the elastic member 215. The limit block 110 limits the rotation angle of the water receiving trough 211, so that the water receiving trough 211 is in a tilted state toward the drainage structure 220, while being able to receive water dripping from the leakage hole.

[0039] Figure 6 The schematic diagram is of the state of the water receiving tank 211 after the wet curtain 500 is installed in the shell 100. The wet curtain 500 squeezes the water receiving tank 211 out of the wet curtain 500 installation area, and the water receiving tank 211 rotates and retracts. The wet curtain 500 corresponds to the bottom of the water leakage hole. Water flows down from the water storage tank 410 through the water leakage hole, and wets the wet curtain 500 after falling on the wet curtain 500. The fan body 300 works to evaporate the water and absorb the heat in the air to achieve a cooling effect.

[0040] In this solution, the drainage structure 220 is arranged longitudinally and tilted, and the drainage structure 220 can be a groove arranged on the housing 100, or a component of a groove structure, and the drainage structure 220 is fixedly installed on the housing 100. When the drainage structure 220 is a groove, the drainage structure 220 can be formed by vertically arranging a partition on the housing 100.

[0041] This embodiment further provides a housing 100 including the protective structure 200 .

[0042] This embodiment further provides a cooling fan, comprising the above-mentioned protective structure 200 .

[0043] In summary, the present solution provides a protective structure 200, a shell 100 including the protective structure 200, and a cold fan. The protective structure 200 includes a water receiving structure 210 and a guide structure. The water receiving structure 210 is rotatably installed on the shell 100. When the cold fan is not installed with a wet curtain 500, the water receiving structure 210 automatically rotates and opens. The water receiving structure 210 receives water dripping from the leaking hole, and the guide structure 220 guides the water collected by the water receiving structure 210 to flow to a water tank at the bottom of the cold fan. When the cold fan is used without installing the wet curtain 500, water can be prevented from flowing to the fan motor fan, thereby avoiding splashing and dripping noise from the fan, ensuring the proper use of the fan blowing function, and improving the electrical safety of the cold fan. After the wet curtain 500 is installed, the wet curtain 500 squeezes the water receiving groove 211 out of the wet curtain 500 installation area, and the water receiving groove 211 rotates and retracts. The wet curtain 500 corresponds to the water leakage hole below. Water flows down from the water storage tank 410 through the water leakage hole, and wets the wet curtain 500 after falling on it, thereby ensuring the cooling function of the cold fan.
