Those skilled in the art can understand the specific meaning of the above terms in this invention based on the specific circumstances.

[0033] The following is for reference. Figures 1-7 The cooling fan assembly 100 according to an embodiment of the present invention allows water in the main water chamber 31 to enter the first chamber 321 under gravity, and water in the second chamber 322 to flow to the wet curtain 2 under gravity, thereby achieving water supply to the wet curtain 2 and thus realizing the cooling function of the cooling fan assembly 100. In addition, this process can reduce the need for a water pump, thereby reducing installation costs, improving assembly efficiency, and reducing noise and the possibility of malfunction of the cooling fan assembly 100, which is conducive to improving user satisfaction.

[0034] like Figure 1 As shown, a cooling fan assembly 100 according to an embodiment of the present invention includes: a cooling fan impeller 1, a wet curtain 2, and a water tank 3.

[0035] The wet curtain 2 and the cold air impeller 1 are distributed along the airflow direction of the cold air impeller 1; the water tank 3 forms a main water chamber 31 and a water supply chamber 32. The water supply chamber 32 includes a first chamber 321 and a second chamber 322. At least a part of the main water chamber 31 is located above the first chamber 321. The main water chamber 31 is used to supply water to the first chamber 321. The second chamber 322 is located above the wet curtain 2. The second chamber 322 is used to supply water to the wet curtain 2. A water suction element 4 is provided in the water supply chamber 32. The water suction element 4 is used to suck water from the first chamber 321 to the second chamber 322.

[0036] Specifically, a evaporative air cooler, also known as an air conditioning fan, is a type of air conditioner. It is equipped with a cold source that is used to cool water. The airflow delivered by the evaporative air cooler can exchange heat with the cooled water, allowing the evaporative air cooler to blow out cool air, thereby achieving a cooling effect. In addition, evaporative air coolers are energy-saving and environmentally friendly, easy to move and carry, can increase indoor humidity, and ensure a good user experience.

[0037] The air cooler assembly 100 is equipped with an air cooler impeller 1, and the air cooler impeller 1 is equipped with a corresponding drive motor. The output shaft of the drive motor is connected to the air cooler impeller 1. When the drive motor is running, it can transmit power to the air cooler impeller 1 through the output shaft to make the air cooler impeller 1 rotate. When the air cooler impeller 1 rotates, it can drive the air around it to flow. A motor mounting bracket is provided in the air cooler assembly 100, and the drive motor is fixedly installed in the motor mounting bracket to ensure the reliability of the operation of the drive motor and the air cooler impeller 1.

[0038] Furthermore, the air cooler assembly 100 is also equipped with a wet curtain 2. Low-temperature water cooled by the cold source can flow through the wet curtain 2. The wet curtain 2 and the air cooler impeller 1 are distributed along the airflow direction of the air cooler impeller 1, so that the airflow driven by the air cooler impeller 1 can flow through the wet curtain 2. In this way, the wet curtain 2, which is soaked in low-temperature water, can cool the airflow. The cooled airflow can be delivered to the room through the air cooler impeller 1 to cool the room. This ensures the environmental friendliness of the air cooler assembly 100 and increases the humidity of the airflow flowing through the wet curtain 2 to ensure the humidity of the indoor environment and improve the user's comfort.

[0039] In addition, the air cooler assembly 100 is equipped with a water tank 3, which stores water to supply water to the evaporative cooling pad 2. The water tank 3 has a relatively large volume, allowing it to hold a larger amount of water, thus reducing the frequency of water refills and improving ease of use and user experience. The water tank 3 forms a main water chamber 31 and a water supply chamber 32. The main water chamber 31 stores water, and the water supply chamber 32 supplies water to the evaporative cooling pad 2. Therefore, the volume of the main water chamber 31 can be made larger than that of the water supply chamber 32 to reduce the need for refilling. The frequency of water refills by the user helps improve user satisfaction. The water supply chamber 32 includes a first chamber 321 and a second chamber 322. The main water chamber 31 is used to supply water to the first chamber 321, and the second chamber 322 is used to supply water to the wet curtain 2. The main water chamber 31 is connected to the first chamber 321, and the second chamber 322 is connected to the wet curtain 2. This allows water in the main water chamber 31 to enter the first chamber 321, that is, to enter the water supply chamber 32, and then flow from the water supply chamber 32 through the second chamber 322 to the wet curtain 2, thereby supplying water to the wet curtain 2.

[0040] Meanwhile, a water-absorbing component 4 is provided in the water supply chamber 32. The water-absorbing component 4 is used to absorb water from the first chamber 321 to the second chamber 322. The water-absorbing component 4 can be connected to both the first chamber 321 and the second chamber 322 at the same time, so that the water-absorbing component 4 can use its water-absorbing properties to guide the water in the first chamber 321 to the second chamber 322. Thus, the water in the main water chamber 31 can pass through the first chamber 321 and the second chamber 322 in sequence, and finally flow from the second chamber 322 to the wet curtain 2 to supply water to the wet curtain 2.

[0041] Furthermore, by positioning at least a portion of the main water chamber 31 above the first chamber 321, or by positioning part or all of the main water chamber 31 above the first chamber 321, and by connecting the main water chamber 31 with the first chamber 321, water in the main water chamber 31 can enter the first chamber 321 under gravity. Simultaneously, by positioning the second chamber 322 above the wet curtain 2, a drain hole can be provided at the bottom of the second chamber 322, allowing water in the second chamber 322 to drip onto the wet curtain 2 under gravity. Through this process, water in the main water chamber 31 can first enter the first chamber 321 under gravity, and then flow from the second chamber 322 to the wet curtain 2 under gravity. This reduces the need for a water pump, lowers installation costs, improves assembly efficiency, and reduces noise and the possibility of malfunctions in the cooling fan assembly 100, thereby enhancing user satisfaction.

[0042] According to an embodiment of the present invention, the cooling fan assembly 100, by disposing at least a portion of the main water chamber 31 above the first chamber 321, allows water in the main water chamber 31 to enter the first chamber 321 under gravity. By providing a water suction member 4, the water in the first chamber 321 can be diverted to the second chamber 322. Furthermore, by disposing the second chamber 322 above the wet curtain 2, the water in the second chamber 322 can flow towards the wet curtain 2 under gravity, thereby achieving water supply to the wet curtain 2 and thus realizing the cooling function of the cooling fan assembly 100. Through this process, the need for a water pump can be reduced, thereby reducing installation costs, improving assembly efficiency, and reducing noise and the possibility of malfunction of the cooling fan assembly 100, which is conducive to improving user satisfaction.

[0043] In some embodiments, the absorbent 4 is made of a permeable material, with at least a portion of one end of the absorbent 4 located in the first cavity 321 and at least a portion of the other end located in the second cavity 322.

[0044] Specifically, the first cavity 321 can supply water to the second cavity 322 through the water-absorbing member 4. At least one end of the water-absorbing member 4 is disposed in the first cavity 321, and at least one end of the other end is disposed in the second cavity 322. The water-absorbing member 4 is constructed to have a certain length so that both ends of the water-absorbing member 4 can extend to the first cavity 321 and the second cavity 322 respectively. This allows the water-absorbing member 4 to drain the water in the first cavity 321 to the second cavity 322, so as to supply water to the wet curtain 2. The water-absorbing member 4 is made of a permeable material, such as cotton or cloth, so that the water-absorbing member 4 has the property of absorbing water, thereby allowing the water-absorbing member 4 to drain the water in the first cavity 321 to the second cavity 322.

[0045] Furthermore, the first cavity 321 and the second cavity 322 can be distributed horizontally, so that the setting height of the first cavity 321 is equal to the setting height of the second cavity 322. This allows the two ends of the water-absorbing component 4 to remain balanced, preventing the water-absorbing component 4 from falling and failing due to the height difference between the first cavity 321 and the second cavity 322, thereby improving the reliability of the water-absorbing component 4. Alternatively, the setting height of the first cavity 321 can be higher than the setting height of the second cavity 322, so that the water on the water-absorbing component 4 can flow quickly to the second cavity 322 under the action of gravity, thereby improving the efficiency and reliability of water supply from the first cavity 321 to the second cavity 322.

[0046] It should also be noted that the water-absorbing component 4 can be made of reverse osmosis material to prevent the water-absorbing component 4 from drawing water from the second chamber 322 back to the first chamber 321, thereby improving the reliability of water supply from the first chamber 321 to the second chamber 322 and the reliability of water supply from the second chamber 322 to the wet curtain 2.

[0047] In some embodiments, the inner bottom wall of the water supply chamber 32 is provided with an upwardly protruding support portion 323, the first chamber 321 and the second chamber 322 are located on both sides of the support portion 323, and the middle part of the water absorption member 4 is supported by the support portion 323 and is higher than both ends of the water absorption member 4.

[0048] Specifically, such as Figures 5-7 As shown, a support portion 323 is provided on the inner bottom wall of the water supply cavity 32, which can be fixed to the inner bottom wall of the water supply cavity 32 to achieve reliable installation of the support portion 323. The first cavity 321 and the second cavity 322 are respectively arranged on both sides of the support portion 323, that is, the support portion 323 can be used to separate the first cavity 321 and the second cavity 322 to avoid interference between them. The support portion 323 is constructed to protrude upward from the inner bottom wall of the water supply cavity 32, so that the support portion 323 extends upward from the inner bottom wall of the water supply cavity 32, so that the support portion 323 can have a certain length, thereby improving the reliability of the support portion 323 in separating the first cavity 321 and the second cavity 322.

[0049] Furthermore, by extending both ends of the water-absorbing component 4 to the first cavity 321 and the second cavity 322 respectively, and supporting the middle part of the water-absorbing component 4 on the support part 323 and above the two ends of the water-absorbing component 4, the water-absorbing component 4 can be constructed into a U-shape. This allows the water-absorbing component 4 to be placed above the support part 323, and both ends of the support part 323 can extend downward from the middle part of the support part 323 to the first cavity 321 and the second cavity 322 respectively. This allows water in the first cavity 321 to enter the second cavity 322 along the water-absorbing component 4. At the same time, the support part 323 can support the water-absorbing component 4 from below the middle part of the water-absorbing component 4, which can prevent the water-absorbing component 4 from falling and failing, thereby improving the reliability of the water-absorbing component 4.

[0050] In some embodiments, the first cavity 321 and the second cavity 322 are both located below the main water cavity 31.

[0051] Specifically, the main water chamber 31 is used to supply water to the first chamber 321. The first chamber 321 is located below the main water chamber 31, so that the water in the main water chamber 31 can enter the first chamber 321 under the action of gravity. This reduces the need for a water pump, lowers the installation cost, improves assembly efficiency, and reduces noise and the possibility of malfunction of the cooling fan assembly 100. The first chamber 321 and the second chamber 322 are distributed in the horizontal direction, that is, the second chamber 322 is also located below the main water chamber 31. Moreover, the second chamber 322 is used to supply water to the wet curtain 2. The second chamber 322 is located below the main water chamber 31, which can prevent the main water chamber 31 from blocking the second chamber 322, thus preventing the second chamber 322 from supplying water to the wet curtain 2 or reducing the efficiency of water supply.

[0052] In some embodiments, multiple water-absorbing elements 4 are provided, and the multiple water-absorbing elements 4 are arranged side by side in the water supply chamber 32; wherein, the second chamber 322 includes multiple spaced sub-chambers 3221, the multiple water-absorbing elements 4 correspond one-to-one with the multiple sub-chambers 3221, and at least a portion of the other end of each water-absorbing element 4 extends into the corresponding sub-chamber 3221.

[0053] Specifically, the water-absorbing component 4 is used to guide the water in the first chamber 321 to the second chamber 322 for water supply to the second chamber 322. Multiple water-absorbing components 4 can be configured, that is, the number of water-absorbing components 4 can be two, three or more. Thus, by having multiple water-absorbing components 4 simultaneously guide the water in the first chamber 321 to the second chamber 322, the rate and reliability of water supply to the second chamber 322 can be improved. Furthermore, by distributing multiple water-absorbing components 4 side by side in the water supply chamber 32, the multiple water-absorbing components 4 can be neatly arranged in the water supply chamber 32, thereby reducing the space occupied by the water-absorbing components 4 in the water supply chamber 32 and avoiding interference between multiple water-absorbing components 4, which would reduce the efficiency of water supply to the second chamber 322.

[0054] Furthermore, multiple sub-chambers 3221 are provided in the second cavity 322, allowing water to be supplied to the multiple sub-chambers 3221 through the first cavity 321. Multiple water-absorbing elements 4 are associated one-to-one with the multiple sub-chambers 3221, meaning that for each sub-chamber 3221, a water-absorbing element 4 is provided to guide water from the first cavity 321 to the corresponding sub-chamber 3221. At least a portion of the other end of each water-absorbing element 4 extends into the corresponding sub-chamber 3221, improving the reliability of water supply to the corresponding sub-chamber 3221 through the water-absorbing element 4. Moreover, the multiple sub-chambers 3221 are spaced apart, allowing the multiple water-absorbing elements 4 to be spaced apart, further preventing interference between the multiple water-absorbing elements 4 and avoiding excessive or insufficient water in some sub-chambers 3221. This ensures a uniform water supply to the multiple sub-chambers 3221 through the multiple water-absorbing elements 4.

[0055] Furthermore, it should be noted that multiple sub-chambers 3221 can be distributed along the extension direction of the wet curtain 2, so that each sub-chamber 3221 is directly opposite the wet curtain 2, and a water leakage hole is provided at the bottom of each sub-chamber 3221, so that the water in the multiple sub-chambers 3221 can drip onto the wet curtain 2 under the action of gravity, thereby supplying water to the wet curtain 2 evenly.

[0056] In such Figures 2-5 and Figure 7 In the embodiment shown, there are nine water-absorbing elements 4, and the nine water-absorbing elements 4 are distributed sequentially in the water supply chamber 32. The water in the first chamber 321 can be simultaneously diverted to the second chamber 322 by the nine water-absorbing elements 4, which can improve the rate and reliability of diverting the water in the first chamber 321 to the second chamber 322.

[0057] In some embodiments, the cooling fan assembly 100 further includes a water tank 5 located below the evaporative cooling pad 2.

[0058] Specifically, the water storage tank 5 has a certain volume and can be used to store excess water. For example, if the cold air impeller 1 malfunctions or the whole machine loses power, the water in the second chamber 322 will still drip onto the wet curtain 2 under the action of gravity. At this time, the water on the wet curtain 2 will flow downward along the wet curtain 2 because it cannot evaporate quickly under the action of the cold air impeller 1. By placing the water storage tank 5 below the wet curtain 2, the excess water on the wet curtain 2 can drip into the water storage tank 5. The water storage tank 5 can be used to catch the excess water on the wet curtain 2 to prevent it from dripping onto the ground and causing inconvenience to the user. Furthermore, by extending at least part of the bottom of the wet curtain 2 into the water storage tank 5, the bottom of the wet curtain 2 can be connected to the water storage tank 5, so that the excess water on the wet curtain 2 can flow downward along the wet curtain 2 and drip from the bottom of the wet curtain 2 into the water storage tank 5. This can improve the reliability of the excess water dripping onto the water storage tank 5 and effectively prevent excess water from dripping onto the ground.

[0059] Furthermore, it should be noted that at least a portion of the bottom of the wet curtain 2 can be extended into the water storage tank 5 so that when the second chamber 322 stops supplying water to the wet curtain 2, the wet curtain 2 can absorb water from the water storage tank 5 in the reverse direction. That is, the bottom of the wet curtain 2 can be extended to the inner bottom wall of the water storage tank 5 so that the wet curtain 2 can completely absorb the water in the water storage tank 5. This can prevent residual water from remaining in the water storage tank 5, and thus prevent residual water from deteriorating and breeding bacteria due to failure to clean it in time.

[0060] In some embodiments, the bottom of the main water chamber 31 is provided with a water outlet 311, the main water chamber 31 is connected to the first chamber 321 through the water outlet 311, and a switch 6 is provided at the water outlet 311.

[0061] Specifically, an outlet 311 is provided in the main water chamber 31. The outlet 311 connects the inside of the main water chamber 31 with the outside, allowing water to be added to or discharged from the main water chamber 31. The main water chamber 31 is also connected to the first chamber 321 through the outlet 311, so that water in the main water chamber 31 can flow to the first chamber 321 through the outlet 311, thus supplying water from the main water chamber 31 to the first chamber 321. The outlet 311 is located at the bottom of the main water chamber 31, and the main water chamber 31 is located above the first chamber 321. This allows water in the main water chamber 31 to flow to the first chamber 321 under the action of gravity, reducing the need for a water pump, lowering installation costs, improving assembly efficiency, and reducing noise and the possibility of malfunction of the cooling fan assembly 100.

[0062] It should be noted that the main water chamber 31 is connected to the first chamber 321 through the outlet 311, so that the main water chamber 31 can supply water to the first chamber 321 using the principle of communicating vessels, and the amount of water in the first chamber 321 can be controlled.

[0063] Furthermore, a switch 6 is provided at the outlet 311. The switch 6 is used to open or close the outlet 311 to control the water supply from the main water chamber 31 to the first chamber 321. The switch 6 is configured to be movable relative to the water tank 3, so that when the switch 6 is movable relative to the water tank 3, it can open or close the outlet 311. When the switch 6 opens the outlet 311, the main water chamber 31 can supply water to the first chamber 321. When the switch 6 closes the outlet 311, the main water chamber 31 cannot supply water to the first chamber 321. The switch 6 is positioned at the outlet 311 so that it can be close to the outlet 311 to control the opening or closing of the outlet 311.

[0064] In some embodiments, a floating element 7 is provided in the water storage tank 5, which is adapted to drive the switch element 6 to open or close the water outlet 311 according to the water level in the water storage tank 5.

[0065] Specifically, the switch 6 can move relative to the water tank 3 to open or close the outlet 311, controlling the water supply from the main water chamber 31 to the first chamber 321. A floating element 7 is installed in the water storage tank 5. The floating element 7 has buoyancy and can drive the switch 6 to open or close the outlet 311 according to the water level in the water storage tank 5. That is, when the water level in the water storage tank 5 rises, the floating element 7 can rise with the water level. At this time, the floating element 7 can drive the switch 6 to move to close the outlet 311, so that the main water chamber 31 stops supplying water to the first chamber 321. When the water level in the water storage tank 5 drops, the floating element 7 can drop with the water level. At this time, the floating element 7 can drive the switch 6 to move to open the outlet 311, so that the main water chamber 31 can supply water to the first chamber 321.

[0066] It should be noted that, in actual design, the movement of the floating component 7 in the horizontal direction can be restricted to improve the reliability of the floating component 7 driving the switch component 6 to open or close the outlet 311.

[0067] In some embodiments, the floating member 7 is connected to a push rod 8, the lower end of the push rod 8 extends into the water storage tank 5 and is connected to the floating member 7, and the upper end of the push rod 8 extends into the first cavity 321 and is connected to the switch member 6.

[0068] Specifically, the floating component 7 can drive the switch component 6 to move to open or close the outlet 311. The push rod 8 is extended vertically, with its upper end extending into the first cavity 321 and connected to the switch component 6, and its lower end extending into the water storage tank 5 and connected to the floating component 7. Thus, the two ends of the push rod 8 are connected to the switch component 6 and the floating component 7 respectively, thereby achieving the connection between the switch component 6 and the floating component 7 through the push rod 8. The floating component 7 can drive the switch component 6 to move through the push rod 8. When the water level in the water storage tank 5 rises, the floating component 7 can drive the switch component 6 to move through the push rod 8 to close the outlet 311. When the water level in the water storage tank 5 drops, the floating component 7 can drive the switch component 6 to move through the push rod 8 to open the outlet 311.

[0069] Therefore, when the cooling fan 1 malfunctions or the entire machine loses power, the water in the main water chamber 31 will still flow to the first chamber 321 under gravity, and the water in the second chamber 322 will also still flow to the wet curtain 2 under gravity. However, the water on the wet curtain 2 cannot evaporate quickly under the action of the cooling fan 1, so the unevaporated water on the wet curtain 2 will flow to the water storage tank 5. When the water volume in the water storage tank 5 increases and the water level rises, the floating component 7 will drive the switch component 6 to move to close the water outlet 311, so that the main water chamber 31 will no longer supply water to the first chamber 321, and the second chamber 322 will also flow to the wet curtain 2. 2 will not continue to supply water to the wet curtain 2, which can prevent excessive water overflow in the water storage tank 5. At this time, the wet curtain 2 can absorb the water in the water storage tank 5 and make it evaporate. When the water in the water storage tank 5 decreases and the water level drops, the floating part 7 will drive the switch part 6 to move to open the water outlet 311. At this time, the main water chamber 31 can continue to supply water to the first chamber 321, and the second chamber 322 can also continue to supply water to the wet curtain 2. This cycle can completely consume the water in the main water chamber 31, which can prevent the water tank 3 from having residual water. This can prevent the residual water from deteriorating and breeding bacteria due to not cleaning it in time.

[0070] In some embodiments, the switch 6 is configured as a rotating baffle that is rotatably connected to the water tank 3; or, the switch 6 is configured as a sealing plug that is movable within the water tank 3.

[0071] Specifically, the switch 6 can move relative to the water tank 3 to open or close the outlet 311. The switch 6 can be configured as a rotating baffle, and the rotating baffle is rotatably connected to the water tank 3 so that the rotating baffle can rotate relative to the water tank 3, so that the outlet 311 can be opened or closed while rotating. The size of the rotating baffle can be configured to be larger than the size of the outlet 311, so that the rotating baffle can completely cover the outlet 311 when closing the outlet 311, thereby improving the reliability of closing the outlet 311.

[0072] Furthermore, when the water level in the water storage tank 5 rises, the push rod 8 can move upward under the action of the floating member 7. At this time, the push rod 8 can press against the rotating baffle and push the rotating baffle to rotate relative to the water tank 3 to close the outlet 311. When the water level in the water storage tank 5 drops, the push rod 8 can move downward under the action of the floating member 7. At this time, the push rod 8 can separate from the rotating baffle, and the rotating baffle can rotate relative to the water tank 3 under its own gravity to open the outlet 311.

[0073] Or, such as Figures 2-3 As shown, the switch 6 can also be constructed as a sealing plug, and the sealing plug can be movable within the water tank 3 so that the outlet 311 can be opened or closed while it is moving. The sealing plug and the outlet 311 can be interference fit so that the sealing plug can completely seal the outlet 311 when it is closed, thereby improving the reliability of closing the outlet 311.

[0074] Furthermore, the sealing plug can be connected to the upper end of the top rod 8, so that the sealing plug can move in the vertical direction relative to the water tank 3 under the action of the floating part 7. When the water level in the water tank 5 rises, the floating part 7 can drive the sealing plug to move upward through the top rod 8 to seal the water outlet 311, thereby closing the water outlet 311. When the water level in the water tank 5 drops, the floating part 7 can drive the sealing plug to move downward through the top rod 8 to move away from the water outlet 311, thereby opening the water outlet 311.

[0075] In some embodiments, the water-absorbing element 4 is detachably installed in the water supply chamber 32.

[0076] Specifically, the water-absorbing component 4 is used to guide the water in the first chamber 321 to the second chamber 322. Multiple water-absorbing components 4 can work together to guide the water from the first chamber 321 to the second chamber 322, improving the rate and reliability of this process. Furthermore, the water-absorbing component 4 is detachably installed in the water supply chamber 32, allowing multiple components to be detachably installed within the water supply chamber 32. This facilitates the individual installation or removal of multiple components, enabling selective installation of multiple components. The number of components installed can be controlled, and by changing the number of components installed, the rate at which water enters the second chamber 322 from the first chamber 321 can be controlled, thus controlling the rate at which the second chamber 322 supplies water to the wet curtain 2. This allows users to choose according to their needs, improving user satisfaction.

[0077] It should also be noted that, in actual use, the water-absorbing part 4 of different materials can be replaced as needed to control the rate at which water is supplied from the first chamber 321 to the second chamber 322.
