In addition, the technical solutions between the various embodiments can be combined with each other, but they must be based on the ability of ordinary technicians in the field to implement them. When the combination of technical solutions is contradictory or cannot be implemented, it should be deemed that such a combination of technical solutions does not exist and is not within the scope of protection required by the present invention.

[0029] The invention provides a cooling fan.

[0030] In the embodiments of the present invention, please refer to Figure 1 , Figure 3 , Figure 4 and Figure 5The air cooler includes a shell 100, a first water tank 200 and a first water curtain 300; the shell 100 is provided with an air inlet 110 and an air outlet 120; the first water tank 200 is arranged in the shell 100, and the first water tank 200 has an air duct area 201 and a water storage area 202 isolated from each other, the air duct area 201 connects the air inlet 110 and the air outlet 120, and the water storage area 202 surrounds the air duct area 201.

[0031] The function of the air cooler is to blow cold air into the room through the air duct after the external hot air passes through the internal heat exchanger, so as to cool the indoor air. Therefore, the air cooler usually also has a heat exchanger, which can be a copper tube filled with refrigerant or a cooling water curtain, and the heat exchanger is usually arranged corresponding to the air inlet 110 of the housing 100. The heat exchanger in the technical solution of the present invention can be a water curtain; or the heat exchanger can be a copper tube filled with refrigerant; or a water curtain and a copper tube filled with refrigerant.

[0032] It can be understood that when the heat exchanger is a water curtain, in one embodiment, the air cooler may have only one water tank, namely the first water tank 200, and the water curtain may be arranged above the water storage area 202 of the first water tank 200; when the water curtain is arranged above the water storage area 202, the water pump on the water curtain pumps the water in the water storage area 202 to above the water curtain, and the water falls through the water curtain, and the water falling through the water curtain can also fall back into the water storage area 202.

[0033] In another embodiment, a water curtain may be provided below the first water tank 200, and another water tank may be provided below the water curtain, so that the water in the first water tank 200 can fall through the water curtain, and the water tank below the water curtain can receive the water falling from the water curtain; in this embodiment, the water curtain may be provided corresponding to the water storage area 202, and the water storage area 202 may be provided with a drain, so that the water in the water storage tank flows onto the water curtain through the drain, and falls into the water tank below the water curtain through the water curtain; or the water curtain may not be provided corresponding to the water storage area 202, in which case a water pump may be provided to pump the water in the water storage area 202 to the top of the water curtain, and then the water falls through the water curtain to the water tank below the water curtain.

[0034] The first water tank 200 in the technical solution of the present invention also has a duct area 201 isolated from the water storage area 202, and the water storage area 202 surrounds the duct area 201. It can be understood that the duct area 201 is formed in the middle or near the middle of the first water tank 200, and the duct area 201 and the water storage area 202 are an integral structure, so that on the one hand, on the basis of storing a part of water, it also provides space for the installation of components in the duct (such as the installation of the fan) and the formation of the duct, thereby achieving the effect of the air cooler occupying a smaller space. Further, it can be understood that when the air cooler is working, the noise at the duct area 201 is relatively large. The water storage area 202 in the technical solution of the present invention surrounds the duct area 201, so that the duct area 201 is surrounded by water, so that the water in the water storage area 202 has a mitigating effect on the vibration generated in the duct area 201, achieving the effect of reducing vibration and noise. In addition, the water storage area 202 and the air duct area 201 are isolated from each other to prevent water from entering the air duct area 201 and affecting the air outlet effect, and to prevent components in the air duct area 201 from being soaked in water and damaged.

[0035] The technical solution of the present invention is connected with the air inlet 110 and the air outlet 120 of the housing 100 through the air duct area 201, so that the external air can enter the housing 100 only through the air inlet 110 for heat exchange, and then can be blown into the room through the air duct area 201 and the air outlet 120 in sequence. In addition, the first water tank 200 in the technical solution of the present invention has an air duct area 201 and a water storage area 202 that are isolated from each other, so that the air duct area 201 and the water storage area 202 do not interfere with each other, and each realizes its own function; in addition, the water storage area 202 surrounds the outside of the air duct area 201, so that the outside of the air duct area 201 is surrounded by the water in the water storage area 202, thereby reducing the vibration outside the air duct area 201, and effectively achieving the effect of vibration reduction and noise reduction.

[0036] For details, please refer to Figure 4 and Figure 5 The first water tank 200 includes a bottom plate 210, a side plate 220 and a connecting plate 230; a baffle 240 is protruding from the bottom plate 210, and the baffle 240 is enclosed in a semi-closed state to form an air duct area 201; the side plate 220 is arranged around the baffle 240 and connected to the bottom plate 210; the two ends of the connecting plate 230 are respectively connected to the adjacent side plates 220 and baffles 240, and the connecting plate 230, the side plates 220 and the baffles 240 enclose a water storage area 202.

[0037] The baffle 240 is semi-enclosed and encloses the air duct area 201, so it can be understood that the baffle 240 is used to separate the air duct area 201 from the water storage area 202, thereby preventing the water in the water storage area 202 from entering the air duct area 201. The side plate 220 surrounds the outside of the baffle 240, and the shape enclosed by the side plate 220 can be the same as the shape enclosed by the baffle 240, or it can be different from the shape enclosed by the baffle 240. For example, the shape enclosed by the baffle 240 is a volute shape, that is, a shape formed by a combination of a ring and a line. The side plate 220 can also be enclosed to form a volute shape, or the side plate 220 can be enclosed to form a regular shape such as a circle or a rectangle. Of course, the side plate 220 can also be enclosed to form other special shapes. The connecting plate 230 connects the adjacent side plates 220 and baffles 240, so that the connecting plate 230, the side plates 220 and the baffles 240 can be enclosed to form a closed shape, thereby ensuring that the enclosed water storage area 202 does not have too many openings, thereby preventing a large amount of water in the water storage area 202 from flowing out. It should be noted that "the baffles 240 are enclosed to form a semi-enclosed state" in the technical solution of the present invention means that the shape enclosed by the baffles 240 has an opening, and the size of the opening is not specifically limited.

[0038] Please refer to Figure 4 and Figure 5 It can be understood that the fan installed in the air duct area 201 has a certain height. In order to make the fan be installed more stably and the water storage area 202, the air duct area 201 and the components installed in the air duct area 201 occupy less space after installation, in this embodiment, part of the bottom plate 210 is arched upward to form a support table 211, the baffle 240 is protruded from the periphery of the support table 211, and the support table 211 is provided with an installation opening 250.

[0039] The installation opening 250 provided in the support table 211 can be used to install the fan, and the support table 211 has a supporting effect on the installation of the fan. By forming the support table 211 by arching upward from one edge of the bottom plate 210 to the middle of the bottom plate 210, the fan in the air duct area 201 is at least partially consistent with the installation space of the water storage tank in the vertical installation direction, thereby avoiding the overall installation size of the fan and the water storage tank in the vertical installation direction being large. In addition, the baffle 240 is convexly arranged on the periphery of the support table 211, so that the baffle 240 can achieve the effect of isolating the air duct area 201 from the water storage area 202.

[0040] For details, please refer to Figure 4 and Figure 5 The baffle 240 includes a first sub-baffle 241 and a second sub-baffle 242; the first sub-baffle 241 is arranged outside a portion of the edge of the mounting opening 250; one end of the second sub-baffle 242 is connected to the first sub-baffle 241, and the other end extends toward the edge of the bottom plate 210.

[0041] With such a configuration, the baffle 240 and the support table 211 can be enclosed together to form the air duct area 201, so that when a fan is installed at the installation port 250, external air can be sucked into the air duct from the axial direction of the fan, and then blown to the edge of the bottom plate 210 through the air duct area 201, and then discharged to the outside of the air cooler through the edge. Among them, the height of the first sub-baffle 241 and the second sub-baffle 242 can be consistent or inconsistent. In order to ensure uniform water blocking at various locations and avoid excessive air volume loss, the first sub-baffle 241 and the second sub-baffle 242 are consistent in height, that is, the top of the first sub-baffle 241 is flush with the top of the second sub-baffle 242. In addition, for ease of installation, the top of the first sub-baffle 241 and the top of the second sub-baffle 242 can be flush with the top of the side plate 220. The second sub-baffle 242 and the first sub-baffle 241 can be smoothly connected, and such a configuration can also avoid the problem of excessive air volume loss.

[0042] Please continue to refer to Figure 4 and Figure 5 In order to further improve space utilization, the support table 211 is set lower than the top of the side plate 220.

[0043] With such an arrangement, the upper part of the fan installed in the installation opening 250 may not be higher than the height of the side panel 220, thereby further improving space utilization and reducing the installation space of the entire air cooler and making it more compact; and further allowing the fan to be surrounded by the water storage area 202, thereby ensuring better vibration reduction and noise reduction effects.

[0044] Please refer to Figure 3 and Figure 4 The fan is prone to shaking during high-speed rotation. In order to prevent the fan from shaking to a large extent, in this embodiment, the inner wall of the installation opening 250 extends in a direction away from the top of the side plate 220 to form a mounting section 260.

[0045] With such an arrangement, the fan can be limited in radial direction by the mounting section 260, thereby improving the installation stability of the fan during rotation and preventing the fan from shaking severely.

[0046] Furthermore, if Figure 6 As shown, in order to improve the strength of the installation section 260, in this embodiment, the first water tank 200 further includes a reinforcing rib 280, one side of the reinforcing rib 280 is connected to the installation section 260, and the other side is connected to the side plate 220.

[0047] By connecting one side of the reinforcing rib 280 to the mounting section 260 and the other side to the side plate 220, the side wall of the mounting section 260 has higher strength, thereby preventing the mounting section 260 from being easily broken by the impact force of the fan when the fan runs at high speed and shakes.

[0048] like Figure 5 As shown, in this embodiment, the water storage area 202 is also provided with an overflow port 270 .

[0049] By providing an overflow port 270 in the water storage area 202, it is convenient to discharge the water in the water storage area 202. Specifically, the overflow port 270 can be provided on the bottom plate 210. Further, in order to have a certain water storage effect, the bottom plate 210 is provided with an overflow section, and the overflow port 270 is opened in the overflow section, and the overflow port 270 is arranged higher than the bottom plate 210. Alternatively, the overflow port 270 can be opened on the side plate 220.

[0050] Furthermore, if Figure 5 As shown, the overflow port 270 is arranged above the support table 211 and below the top end of the baffle 240 .

[0051] By setting the overflow port 270 higher than the support table 211, the water in the water storage area 202 can surround at least a portion of the air duct, thereby further ensuring a good shock reduction and noise reduction effect. In addition, the overflow port 270 is set lower than the top of the baffle 240, which can prevent the water in the water storage area 202 from flowing into the air duct area 201 through the top of the baffle 240, thereby preventing the components in the air duct area 201 from being soaked by water and damaged.

[0052] Please refer to Figures 1 to 4 In this embodiment, the air cooler also includes a second water tank 500, a first water curtain 300 and a second water curtain 400; the second water tank 500 is arranged below the first water tank 200; the first water curtain 300 is arranged above the water storage area 202; the second water curtain 400 is located between the first water tank 200 and the second water tank 500, and is arranged below the overflow port 270; the shell 100 also includes an air suction port 130, the first water curtain 300 is arranged corresponding to the air suction port 130, and the second water curtain 400 is arranged corresponding to the air inlet 110.

[0053] By locating the second water curtain 400 between the first water tank 200 and the second water tank 500 and below the overflow port 270, the water in the first water tank 200 flows onto the second water curtain 400 through the overflow port 270, and then flows into the second water tank 500 through the second water curtain 400. It can be understood in this embodiment that the housing 100 also has an air supply port 140 connected to the air suction port 130, and the first water curtain 300 is arranged corresponding to the air suction port 130, so that the external air will exchange heat through the first water curtain 300 after passing through the air suction port 130, and then blow to the air supply port 140 through the air duct assembly inside the housing 100, and then blow out cold air from the air supply port 140. In addition, the user can first fill water into the first water tank 200, and then a part of the water injected into the first water tank 200 is stored in the water storage area 202, and the other part flows to the second water curtain 400 through the overflow port 270, and then flows to the second water tank 500 through the second water curtain 400. In order to achieve the effect of water circulation, the water in the second water tank 500 can be pumped to the top of the first water curtain 300 by a water pump, and under the action of gravity, it passes through the first water curtain 300, the first water tank 200 and the second water curtain 400 in sequence, and finally enters the second water tank 500, so as to achieve the effect of water recycling. Further, it can be understood that when the water pipe connected to the water pump extends to the top of the first water curtain 300, part of it can correspond to the second water curtain 400, so that when the external air is heat-exchanged by the second water curtain 400, the air can be heat-exchanged with the water in the water pipe again; or when the temperature of the external air is lower than the temperature of the water in the water pipe, the external air can directly exchange heat with the water in the water pipe, thereby ensuring that the temperature of the water pumped to the first water curtain 300 is low, so that the external air has a better heat exchange effect after passing through the first water curtain 300, thereby ensuring that the wind sent out from the air outlet 140 is relatively cool.

[0054] Since other components such as a water pump are arranged in the second water tank 500, the weights at the upper and lower ends of the air cooler are uneven. The present invention provides a first water tank 200 arranged above the second water tank 500, and the first water tank 200 has a water storage area 202. Therefore, when water is stored in the water storage area 202, the weight of the first water tank 200 will increase, thereby making the weight at the first water tank 200 and the weight at the second water tank 500 more even, thereby improving the uniformity of the weight of the entire air cooler.

[0055] The above descriptions are only optional embodiments of the present invention, and are not intended to limit the patent scope of the present invention. All equivalent structural changes made using the contents of the present invention's specification and drawings, or directly / indirectly applied in other related technical fields, are included in the patent protection scope of the present invention.
