[0028] The technical solution of the utility model is further explained below with reference to the accompanying drawings and through specific implementation methods.

[0029] The embodiment of the utility model provides a cooling fan 100 .

[0030] See also Figure 1 , Figure 2 , Figure 3 as well as Figure 5 In one embodiment, the cooling fan 100 includes a housing 110, a suction assembly 120, a water curtain 130, and a fixing frame 140;

[0031] The shell 110 has an air inlet 111 and an air outlet 112; the suction component 120 is close to the air outlet 112 and fixedly connected to the shell 110, and the suction component 120 can draw in outside air from the air inlet 111 and discharge it from the air outlet 112; the water curtain 130 is stored in the fixing frame 140; the side wall of the shell 110 also has an installation port 113, and the fixing frame 140 passes through the installation port 113 and is arranged close to the air inlet 111. The fixing frame 140 is connected to the shell 110 by pulling so that the water curtain 130 can be taken out of the fixing frame 140.

[0032] It can be understood that the embodiment of the utility model is provided with a water curtain 130 and a fixing frame 140, and the water curtain 130 is stored in the fixing frame 140; the side wall of the shell 110 has an installation port 113, and the fixing frame 140 passes through the installation port 113 and is arranged close to the air inlet 111, and the fixing frame 140 is connected to the shell 110 by pulling. When the user needs to observe the sanitary condition of the water curtain 130, the fixing frame 140 is pulled out from the shell 110 to achieve the drying or replacement of the water curtain 130 or observe the sanitary condition of the water curtain 130.

[0033] Furthermore, if Figure 4 As shown, the water curtain 130 is taken out from the fixing frame 140 and the water curtain 130 can be replaced or fully dried.

[0034] Optionally, the material of the water curtain 130 is kraft paper, sponge, HEPA, etc., and the specific type of the water curtain is not limited here.

[0035] See also Figure 3 or Figure 4 In a specific embodiment, the fixing frame 140 also has hollow structures on both sides close to the air inlet 111 and away from the air inlet 111. In order to increase the air circulation efficiency, the area of ​​the hollow structure accounts for more than 70% of the surface of the fixing frame 140.

[0036] See also Figure 3 In order to improve the stability of the fixing frame 140 when being pulled relative to the shell 110 , the bottom of the fixing frame 140 has a guide groove 142 , and a guide rail 115 is provided in the shell 110 , and the guide groove 142 is slidably matched with the guide rail 115 .

[0037] Please continue reading Figure 3 On the basis of the above embodiment, a buckle 141 is provided on one side of the fixing frame 140 close to the installation port 113. The fixing frame 140 has a first hollow portion 140a and a second hollow portion 140b, and the buckle 141 is formed at the connection between the first hollow portion 140a and the second hollow portion 140b. It can be understood that the buckle 141 is a hollow structure to avoid occupying the internal and external structures of the fixing frame 140, improve the utilization of the internal space of the housing 110, and avoid interference with the water curtain 130 during installation. The provision of two hollow portions improves the user's ability to grip the buckle 141.

[0038] See also Figure 1 , Figure 3 and Figure 4 In a preferred embodiment of the present invention, the cooling fan 100 further includes a movable cover plate 150 , and the movable cover plate 150 is covered on the installation opening 113 and movably connected to the housing 110 .

[0039] Alternatively, if Figure 2 As shown, the movable cover 150 is rotatably connected to the shell 110 ; further, in order to facilitate opening of the movable cover 150 rotatably connected to the shell 110 , a groove 151 is provided on the opposite side of the rotating shaft of the movable cover 150 .

[0040] like Figure 4 As shown, in a preferred embodiment, the movable cover 150 includes a snap-in component 152 and an adapter component 153, and the snap-in component 152 and the adapter component 153 are both arranged on the side of the movable cover 150 close to the fixed frame 140, and the snap-in component 152 is snap-fitted with the first hollow portion 140a, and the adapter component 153 is matched with the second hollow portion 140b and can be accommodated in the second hollow portion 140b.

[0041] It is understandable that the clamping member 152 and the adapter member 153 are accommodated in the first hollow portion 140a and the second hollow portion 140b, which can fix the fixing frame 140 and reduce the shaking of the fixing frame 140 inside the housing 110. The horizontal fixation of the fixing frame 140 is realized, and the working noise is reduced. The clamping member 152 is clamped and matched with the first hollow portion 140a, so that the movable cover plate 150 can be connected through the clamping member 152, and the clamping and buckling of the movable cover plate 150 is realized, and the space of the housing 110 occupied by the movable cover plate 150 is greatly reduced, making the appearance of the air cooler 100 more compact and refined.

[0042] Furthermore, if Figure 4 As shown, the protrusion of the clamping member 152 is clamped and matched with the first hollow part 140a near the buckle. It can be understood that the two sides of the buckle 141 are hollow structures of the first hollow part 140a and the second hollow part 140b, so the elastic deformation ability of the buckle 141 is better, which can better realize the clamping protrusion of the clamping member 152 entering the first hollow part 140a or detaching from the first hollow part 140a.

[0043] Furthermore, in order to improve the tightness of the movable cover 150 and the housing 110, a protrusion 154 cooperating with the housing 110 is provided on the opposite side of the rotating shaft of the movable cover 150. Optionally, the protrusion 154 is made of elastic material.

[0044] Optionally, the movable cover 150 is plugged into the housing 110 via a plug-in slot.

[0045] It is understandable that when the movable cover 150 is rotatably connected to the shell 110, the user can flip the cover more quickly, and when the movable cover 150 is plugged into the shell 110 through the plug-in slot, the connection between the movable cover 150 and the shell 110 is more secure.

[0046] See also Figure 5 In a preferred embodiment of the present invention, the cooling fan 100 further includes a filter 160 , and the filter 160 is disposed inside the fixing frame 140 and overlapped with the water curtain 130 .

[0047] Optionally, the filter 160 is a textile fiber filter 160. It is understandable that the filter 160 can filter impurities in the air and prevent excessive pollution inside the water curtain 130 or the housing 110. Furthermore, the filter 160 is arranged in the fixing frame 140, which also facilitates the cleaning and replacement of the filter 160.

[0048] See also Figure 1 and Figure 5 In another embodiment of the utility model, the housing 110 is further provided with a first air guide plate 116 and a second air guide plate 117, both of which are close to the air outlet 112. The first air guide plate 116 is rotatably connected to the housing 110 in the horizontal direction, and the second air guide plate 117 is rotatably connected to the housing 110 in the vertical direction. It can be understood that the rotation of the first air guide plate 116 can adjust the direction of the air outlet 112 sweeping up and down, and the setting of the second air guide plate 117 can realize the horizontal / left-right sweeping of the air outlet 112.

[0049] In a more specific embodiment, Figure 6 As shown, the cooling fan 100 further includes a driving motor 171, a gear 172, a rack 173, and a connecting member 174; the second air guide plate 117 is fixedly connected to one end of the connecting member 174, and the rack 173 is rotatably connected to the other end of the connecting member 174; the driving motor 171 is fixed to the housing 110, and the gear 172 is mounted on the output shaft of the driving motor 171 and meshes with the rack 173. It can be understood that the driving motor 171 drives the gear 172 to rotate alternately clockwise and counterclockwise. Since the driving motor 171 is fixed to the housing 110, the rotation of the gear 172 will drive the rack 173 to move, and the rack 173 moves and then drives the second air guide plate 117 to swing horizontally through the connecting member 174.

[0050] See also Figure 1 and Figure 5In a preferred embodiment of the present invention, the cooling fan 100 also includes an odor sensor 181 and a temperature and humidity sensor 182, and the shell 110 also has an air vent 114, and the odor sensor 181 and the temperature and humidity sensor 182 are arranged inside the shell 110 and close to the air vent 114.

[0051] Optionally, the cooling fan 100 further includes a display screen 190 .

[0052] It is understood that the odor sensor 181 can detect the air quality of the surrounding environment and monitor common harmful gases. The temperature and humidity sensor 182 can detect the temperature and humidity of the surrounding environment so that the user can refer to and select a more suitable fan working mode, such as increasing the suction power of the suction component 120, or reducing the moisture content of the water curtain 130. It is also understood that the display screen 190 can be used to display the environmental parameters detected by the odor sensor 181 and the temperature and humidity sensor 182.

[0053] As described above, the above embodiments are only used to illustrate the technical solutions of the utility model, rather than to limit it. Although the utility model has been described in detail with reference to the aforementioned embodiments, those skilled in the art should understand that the technical solutions described in the aforementioned embodiments can still be modified, or some of the technical features can be replaced by equivalents. However, these modifications or replacements do not deviate the essence of the corresponding technical solutions from the spirit and scope of the technical solutions of the various embodiments of the utility model.
