[0082] In order to make the purpose, technical scheme and advantages of the embodiments of the utility model clearer, the technical scheme in the embodiments of the utility model will be described clearly and completely in combination with the drawings in the embodiments of the utility model. Obviously, the described embodiments are part of the embodiments of the utility model, rather than all the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by those skilled in the art without creative labor belong to the protection scope of the utility model.

[0083] The embodiments of the utility model will be described below in combination with Figures 1 to 17 .

[0084] According to the embodiments of the utility model, on the one hand, an out pipe structure 2 is provided, which is used in a device with a water tank 4 and the out pipe structure 2, is used for guiding a water pipe 5 to the upper side of the water tank 4, and comprises a structure body. An out pipe channel 201 is formed in the structure body, and the out pipe channel 201 is used for the water pipe 5 to pass through. From top to bottom, the out pipe channel 201 extends at least partially in the direction of being drawn away from the device to the water tank 4.

[0085] In use, the water pipe 5 of the outlet structure 2 of this utility model can pass through the outlet channel 201 and extend towards the water tank 4 of the cooling fan in the direction of being drawn out of the cooling fan under the action of the extension section 2011. With this setting, the outlet trend of the water pipe 5 can be changed from downward outlet to outlet towards the baffle 401 of the water tank 4, avoiding the water pipe 5 overlapping with the water tank 4 in the height direction due to the downward outlet of the water pipe 5. This avoids interference between the upper edge of the water tank 4 and the water pipe 5 during the assembly of the water tank 4. The outlet structure 2 of this utility model can overcome the problem that the upper edge of the water tank 4 is prone to interference with the water pipe 5 in the prior art. This not only affects the smoothness and convenience of the installation of the water tank 4 and the user experience, but also causes the water pipe 5 to be squeezed, resulting in insufficient water supply, affecting the performance of the cooling fan, and may even cause the water pipe 5 to be damaged and leak, thereby affecting the normal use of the cooling fan and causing safety hazards.

[0086] For ease of description, the direction in which the water pipe 5 is pulled out of the cooling fan will be defined as the rear side of the cooling fan, and the direction in which the water tank 4 enters the cooling fan will be defined as the front side of the cooling fan.

[0087] It should be noted that the orientation or positional relationship indicated by "front" or "rear" is based on the orientation or positional relationship shown in the accompanying drawings, and is only for the purpose of facilitating the description of this application and simplifying the description, and is not intended to indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of this application.

[0088] Although the device with a water tank and outlet pipe structure in the embodiments of this application is a cooling fan, it is not limited to this. In some embodiments not shown in the figures, the device with a water tank and outlet pipe structure may also be a humidifier or the like.

[0089] In one embodiment, an extension section 2011 is formed on the outlet pipe channel 201. The line connecting the beginning and end of the extension section 2011 is defined as the first line. Along the direction in which the water tank 4 is drawn out of the device, the angle between the first line and the vertical direction is θ1, where 20°≤θ1≤40°.

[0090] When θ1 is within the above range, the water pipe 5 can tend to exit backward, which effectively solves the problem of the upper edge of the water tank 4 squeezing the water pipe 5 due to the downward exit of the water pipe 5 during the installation of the water tank 4, and will not cause damage to the water pipe 5 or increase the flow resistance of the liquid due to excessive bending of the water pipe 5.

[0091] In one embodiment, the extension segment 2011 is an arc segment.

[0092] The arc-shaped extension 2011 helps reduce wear and damage to the water pipe 5 and makes the water flow more smoothly within the water pipe 5.

[0093] As a transformable embodiment, in an embodiment not shown in the drawings, the out-pipe passage 201 is a stepped structure, the beginning end of the extension section 2011 is the inlet end of the out-pipe passage 201, and the end of the extension section 2011 is the outlet end of the out-pipe passage 201. Exemplarily, the extension section 2011 comprises a first section and a second section connected in sequence, the first section extends in the vertical direction, and the second section extends in the horizontal direction.

[0094] As another transformable embodiment, in an embodiment not shown in the drawings, the extension section 2011 is arranged obliquely and is inclined towards the direction of pulling the water pipe 5 out of the device.

[0095] In an embodiment, as shown in Figure 2 and Figure 3 , the extension section 2011 is a circular arc section. As shown in Figure 4 , the central angle of the extension section 2011 is θ1, 40°≤θ2≤80°.

[0096] When the central angle of the extension section 2011 is within the above range, the water pipe 5 can present a tendency to extend backwards, effectively solving the problem that the upper edge of the water tank 4 presses the water pipe 5 due to the downward out-pipe of the water pipe 5 during the installation of the water tank 4, and without causing damage to the water pipe 5 or increasing the flow resistance of the liquid due to excessive bending of the water pipe 5.

[0097] In a preferred embodiment, the central angle of the extension section 2011 is 50°.

[0098] In an embodiment, the out-pipe structure 2 is arranged at the first side 303 of the device, and at least part of the out-pipe passage 201 extends towards the second side 304 of the device from top to bottom, and the first side 303 is arranged opposite to the second side 304.

[0099] By such an arrangement, the guide section 2012 can convert the extension of the water pipe 5 from backwards to the direction towards the second side 304 of the device, thereby facilitating the water pipe 5 to enter the water tank 4 through the wave-preventing plate 401, thereby reducing the problem that the wave-preventing plate 401 prevents the water pipe 5 from entering the water tank 4, causing the water pipe 5 to be bent between the wave-preventing plate 401 and the lower edge of the outer shell 3 of the device, and causing the lower edge of the wave-preventing plate 401 and the outer shell 3 of the water tank 4 to press the water pipe 5 after the installation of the water tank 4.

[0100] The guide section 2012 is formed on the out-pipe passage 201, and the angle between the second connecting line defining the beginning end and the end of the guide section 2012 and the vertical direction is θ3 in the direction from the first side 303 to the second side 304 of the device, 15°≤θ3≤30°.

[0101] When θ3 is within the above range, the water pipe 5 can enter the water tank 4 through the wave-preventing plate 401 without being damaged or increasing the flow resistance of the liquid due to excessive bending of the water pipe 5.

[0102] In one embodiment, as shown in Figure 2 and Figure 3 , the guide segment 2012 is a circular arc segment. In one preferred embodiment, the lower part of the extension segment 2011 forms the guide segment 2012, and the central angle of the guide segment 2012 is θ4, 30°≤θ4≤60°.

[0103] When the central angle of the guide segment 2012 is within the above range, the water pipe 5 can enter the water tank 4 through the wave-preventing plate 401 without being damaged or increasing the flow resistance of the liquid due to excessive bending of the water pipe 5.

[0104] The circular arc-shaped guide segment 2012 can help reduce the wear and damage of the water pipe 5 and make the flow of water in the water pipe 5 smoother.

[0105] Although in the embodiment as shown in Figure 2 and Figure 3 , the lower part of the extension segment 2011 forms the guide segment 2012, the embodiments of the present application are not limited thereto. The extension segment 2011 and the guide segment 2012 can also be formed at the same position of the out-pipe passage 201; or the extension segment 2011 and the guide segment 2012 are alternately arranged along the extension direction of the out-pipe passage; or at least one of the upper part and the lower part of the guide segment 2012 is formed with the extension segment 2011, and the above-mentioned embodiments all fall within the scope of the present application.

[0106] As a convertible embodiment, in an embodiment not shown in the drawings, the guide segment 2012 is a stepped structure, the start end of the guide segment 2012 is the inlet end of the out-pipe passage 201, and the end of the guide segment 2012 is the outlet end of the out-pipe passage 201. Exemplarily, in one alternative embodiment, the guide segment 2012 includes a first segment and a second segment connected in sequence, the first segment extends in the vertical direction, and the second segment extends in the horizontal direction.

[0107] As another convertible embodiment, in an embodiment not shown in the drawings, the guide segment 2012 is arranged obliquely.

[0108] In one preferred embodiment, as shown in Figure 5 , θ4=45°.

[0109] In one preferred embodiment, the air duct plate further includes a reinforcing rib 2015 arranged on the inner wall of the out-pipe passage 201.

[0110] The reinforcing ribs 2015 can enhance the structural strength of the out-pipe structure 2, avoid deformation of the out-pipe structure 2 from affecting the guiding effect of the out-pipe structure 2 on the water pipe 5, and even extrude the water pipe 5.

[0111] In a preferred embodiment, the out-pipe structure 2 has oppositely arranged first and second side walls 2013 and 2014, which are arranged in sequence in a direction approaching the second side 304 of the device, and the reinforcing ribs 2015 include first and second reinforcing ribs 20151 and 20152.

[0112] In the embodiment, as shown in Figure 5 the first reinforcing ribs 20151 are at least two and are arranged in the vertical direction on the first side wall 2013. The second reinforcing ribs 20152 are at least two and are arranged in the vertical direction on the second side wall 2014, and the lowermost second reinforcing rib 20152 is arranged above the lowermost first reinforcing rib 20151.

[0113] In the embodiment, the first and second reinforcing ribs 20152 are arranged in the vertical direction, thereby reducing the influence of the first and second reinforcing ribs 20151 and 20152 on the inner diameter of the second extension section 2011. On this basis, the second reinforcing ribs 20152 are arranged above the first reinforcing ribs 20151, which can further prevent the water pipe 5 from tilting downward or in the first direction, increase the angle of the water pipe 5 out of the second side 304, avoid extrusion of the water pipe 5 by the wave-preventing plate 401 and the lower edge of the shell 3, and make the water pipe 5 more smooth.

[0114] In the embodiment, it should be noted that, although in Figure 2 and Figure 3 the first side 303 is the right side and the second side 304 is the left side, but not limited thereto, the terms "upper", "lower", "left", "right", "front", "back" and the like indicate the orientation or positional relationship based on the orientation or positional relationship shown in the drawings, and are only for the convenience of describing the present application and simplifying the description, and do not indicate or imply that the device or element referred to must have a particular orientation, be constructed and operated in a particular orientation, and therefore cannot be understood as a limitation on the present application.

[0115] In an embodiment, the distance between the first and second reinforcing ribs 20151 and 20152 in the vertical direction is 5.3 mm, which can further reduce the possibility of the water pipe 5 tilting toward the first side 303 of the air cooler, increase the angle of the water pipe 5 out of the second side 304 of the device, avoid extrusion of the water pipe 5 by the wave-preventing plate 401 and the lower edge of the shell 3, and make the water pipe 5 more smooth.

[0116] According to the embodiment of the present application, on the other hand, an air cooler is also provided, which comprisesFigure 6 and Figure 8 As shown, the cooling fan includes a housing 3, an outlet pipe structure according to the first aspect of this utility model, a water tank 4, and a water pipe 5.

[0117] An opening 305 is provided on one side wall of the outer casing 3. The air duct plate is located inside the outer casing 3. The water tank 4 is located below the air duct plate and is removably installed at the opening 305. The water pipe 5 passes through the outlet pipe structure 2 of the air duct plate and extends into the water tank 4.

[0118] The second aspect of this utility model's cooling fan includes or uses the air duct plate of the first aspect of this utility model, thus having its beneficial effects: the water pipe 5 can pass through the outlet channel 201 and, under the action of the extension section 2011, extend towards the direction in which the water tank 4 of the cooling fan is drawn out of the cooling fan. With this arrangement, the outlet trend of the water pipe 5 can be changed from downward outlet to outlet towards the anti-surge plate 401 of the water tank 4, avoiding the water pipe 5 overlapping with the water tank 4 in the height direction due to the downward outlet of the water pipe 5, thereby avoiding interference between the upper edge of the water tank 4 and the water pipe 5 during the assembly of the water tank 4. The cooling fan of this utility model embodiment can overcome the problem in the prior art where the water pipe 5 of the cooling fan obstructs the installation of the water tank 4, is not conducive to the normal flow of water, and may even damage the water pipe 5.

[0119] In one embodiment, a water pump base is provided inside the water tank 4, and a water pump is mounted on the water pump base. One end of the water pipe 5 is connected to the water pump, and the other end passes through the air duct plate and is connected to the drain outlet at the upper end of the air duct plate.

[0120] The water pipe 5 inside the evaporative air cooler is mainly used for the water circulation system. A water pump draws water from the water tank 4 and sprays it evenly onto the evaporative filter layer through a water distribution system. Hot outdoor air enters the evaporative cooling medium, where it exchanges heat thoroughly with the moisture, allowing the hot indoor air to escape outdoors, thus achieving the cooling effect.

[0121] In one embodiment, such as Figure 9 As shown, the water tank 4 includes a water tank body 402 and a wave deflector 401.

[0122] Among them, the wave deflector 401 is installed at the opening 305 of the water tank 4, such as Figure 7 As shown, the wave deflector 401 has an inclined surface 4011, which slopes from top to bottom toward the middle of the water tank 4.

[0123] By so arranging, the water pipe 5 can enter into the water tank 4 along the inclined surface 4011 of the wave-preventing plate 401 after extending out of the pipe structure 2, effectively preventing the wave-preventing plate 401 from preventing the water pipe 5 from entering into the water tank 4, causing the water pipe 5 to be bent between the wave-preventing plate 401 and the lower edge of the shell 3, solving the problem that the water pipe 5 is squeezed between the wave-preventing plate 401 and the lower edge of the shell 3 after the water tank 4 is installed, and making the water pipe 5 more smoothly run.

[0124] In one embodiment, the angle between the inclined surface 4011 and the horizontal direction is θ3, and 30°≤θ3≤60°.

[0125] When the angle between the inclined surface 4011 and the horizontal direction is within the above range, the problem that the water pipe 5 is squeezed between the wave-preventing plate 401 and the lower edge of the shell 3 after the water tank 4 is installed can be solved, and the structural stability of the wave-preventing plate 401 will not be reduced, avoiding increasing the flow resistance of the water flow, or generating noise, and increasing the maintenance cost of the wave-preventing plate 401.

[0126] In one embodiment, as shown in FIG. 4, the wave-preventing plate 401 further comprises a platform portion 4012. The platform portion 4012 and the inclined surface 4011 are sequentially arranged along the direction in which the water tank 4 enters into the shell 3, the shell 3 has a lower edge, and the lower edge is located directly above the platform portion 4012 when the water tank 4 is located in the shell 3, as shown in FIG. 5 and FIG. 6. Figure 7 Figure 16 Figure 17 As shown in FIG. 5 and FIG. 6, the distance between the lower edge and the platform portion 4012 is d1, and the diameter of the water pipe 5 is d2, and 2d2≤d1≤5d2.

[0127] When the proportional relationship between d1 and d2 is within the above range, the wave-preventing plate 401 can effectively prevent the water pipe 5 from entering into the water tank 4, causing the water pipe 5 to be bent between the wave-preventing plate 401 and the lower edge of the shell 3.

[0128] The platform portion 4012 can protect the structural integrity of the water tank 4, prevent the liquid in the water tank 4 from overflowing, improve the stability of the water tank 4, protect the equipment in the water tank 4, and facilitate maintenance and cleaning, and is designed to protect the equipment in the water tank 4 and facilitate maintenance and cleaning.

[0129] Preferably, the smaller the gap between the lower edge of the shell 3 and the wave-preventing plate 401, the larger the inclination angle of the inclined surface 4011 of the wave-preventing plate 401. The larger the inclination angle of the wave-preventing plate 401 of the water tank 4, the easier the water pipe 5 to enter into the inside of the water tank 4 along the inclination; the smaller the inclination angle, the easier the wave-preventing plate to lift the water pipe 5, and a large enough gap is needed to accommodate the lifted water pipe 5.

[0130] Exemplarily, in an optional embodiment, the distance between the wave-preventing plate 401 and the lower edge of the shell 3 is 26.5 mm, and the inclination angle of the wave-preventing plate 401 is set to 45°. ​​

[0131] In one embodiment, the cooling fan further comprises an air duct body 6. The air duct body 6 is arranged in the shell 3, and an air duct plate is detachably arranged on the air duct body 6, and an air duct is formed between the air duct body 6 and the air duct plate.

[0132] The air duct can be used to guide and optimize air flow, so as to improve the working efficiency and performance of the cooling fan.

[0133] In one embodiment, one of the air duct body 6 and the outlet pipe structure 2 is provided with a first limiting groove 202 (see Figure 3 ) and a first clamping portion 203 (see Figure 2 ), and the other of the air duct body 6 and the outlet pipe structure 2 is provided with a first limiting protrusion 601 and a second clamping portion 602 (see Figure 11 ), and when the first limiting protrusion 601 is arranged in the first limiting groove 202, the first clamping portion 203 can be clamped with the second clamping portion 602.

[0134] In this way, the operator can insert the first limiting protrusion 601 into the first limiting groove 202, and when the first limiting protrusion 601 is installed in place, the first clamping portion 203 can be clamped with the second clamping portion 602, so as to reliably limit the outlet pipe structure 2 on the air duct body 6, and the installation process is simple and convenient.

[0135] In one embodiment, one of the air duct plate and the air duct body 6 is provided with a second limiting groove 101 and a third clamping portion 102 (see Figure 15 ), and the other of the air duct plate and the air duct body 6 is provided with a second limiting protrusion 603 and a fourth clamping portion 604 (see Figure 13 ), and when the second limiting protrusion 603 is arranged in the second limiting groove 101, the third clamping portion 102 can be clamped with the fourth clamping portion 604.

[0136] In this way, the operator can insert the second limiting protrusion 603 into the second limiting groove 101, and when the second limiting protrusion 603 is installed in place, the third clamping portion 102 can be clamped with the fourth clamping portion 604, so as to reliably limit the air duct plate on the air duct body 6, and the installation process is simple and convenient.

[0137] In one embodiment, as shown in Figure 6 , the shell 3 comprises a front shell 301 and a rear shell 302, as shown in Figure 12 and Figure 14As shown, one of the front shell 301 and the rear shell 302 is provided with a connecting column 3011, the other of the front shell 301 and the rear shell 302 is provided with a connecting hole 3022, the air duct body 6 is provided with a connecting column via hole 605, the connecting column via hole 605 can be turned over by the connecting column 3011, and the cold air fan further comprises a fastener, the fastener can pass through the connecting column 3011 and the connecting hole 3022 and connect the front shell 301, the air duct body 6 and the rear shell 302.

[0138] In one embodiment, the air duct plate body 1 of the air duct plate is integrally formed with the outlet pipe structure 2.

[0139] In summary, the outlet pipe structure of the first aspect and the cold air fan of the second aspect of the utility model can overcome the problem that the upper edge of the water tank 4 of the cold air fan in the prior art is easy to interfere with the water pipe 5, which not only affects the smoothness and convenience of the installation of the water tank 4, affects the user's use experience, but also causes extrusion to the water pipe 5, causes insufficient water supply, affects the performance of the cold air fan, and even may cause the water pipe 5 to be damaged and leak, and further affects the normal use of the cold air fan and causes a safety hazard.

[0140] Although the embodiments of the utility model are described in combination with the drawings, those skilled in the art can make various modifications and changes without departing from the spirit and scope of the utility model, and such modifications and changes all fall within the scope of the utility model claimed.
