Description

Technical Field

[0001] This utility model relates to the field of household appliance technology, specifically to a wave deflector and a cooling fan. Background Technology

[0002] A typical air cooler includes a housing, an air duct assembly, water pipes, and a water tank. The air duct assembly and water pipes are located inside the housing. An opening is provided on one side wall of the housing. The water tank passes through the opening and is removably mounted on the housing. The air duct assembly has an outlet pipe structure, through which the water pipes extend into the water tank.

[0003] However, in related technologies, the water pipe needs to enter the water tank through the gap between the baffle and the outer shell. However, the baffle and the outer shell can easily squeeze the water pipe, requiring the user to reach into the water tank to adjust the position of the water pipe. This not only affects the smoothness and convenience of water tank installation and increases the user's operation steps and difficulty, but also easily leads to insufficient water supply, affecting the performance of the cooling fan, and may even cause water pipe damage and leakage, thereby affecting the normal use of the cooling fan and creating safety hazards. Utility Model Content

[0004] In view of this, the present invention provides a baffle plate and a cooling fan to solve the problem in the related technology that the baffle plate of the water tank is easily squeezed by the water pipe, which affects the smoothness and convenience of the water tank installation, resulting in insufficient water supply, affecting the performance of the cooling fan, and may even damage the water pipe and cause safety hazards.

[0005] In a first aspect, this utility model provides a wave-damping plate for installation inside a water tank, wherein the top of the water tank has an opening, comprising:

[0006] The plate body is designed for placement at open openings;

[0007] The inclined section, connected to the plate body, extends from top to bottom towards the middle of the water tank.

[0008] Beneficial effects: In the use of the anti-surge plate of this utility model embodiment, the water pipe of the cooling fan can be output from the outlet pipe channel and enter the water tank through the gap between the anti-surge plate and the outer shell along the inclined part. Since the inclined part can extend downward along the direction of the water pipe entering the water tank, the inclined part can guide the water pipe to extend into the water tank at an incline and provide space for the extension of the water pipe.

[0009] Therefore, the anti-surge plate of this utility model embodiment can effectively prevent the anti-surge plate from blocking the water pipe from entering the water tank, causing the water pipe to bend between the anti-surge plate and the outer shell. This overcomes the problem in related technologies where the anti-surge plate of the water tank is easily squeezed by the water pipe, affecting the smoothness and convenience of water tank installation, resulting in insufficient water supply, affecting the performance of the cooling fan, and even potentially damaging the water pipe and causing safety hazards. It can make the water pipe run more smoothly and help improve the user experience.

[0010] In one alternative implementation, the line connecting the beginning and end of the inclined portion is defined as the first line, and the angle between the first line and the horizontal direction is θ1, where 30°≤θ1≤60°.

[0011] Beneficial effects: When the inclined surface θ1 is within the above range, it can solve the problem of the baffle plate squeezing the water pipe with the outer shell after the water tank is installed, and will not reduce the structural stability of the baffle plate, avoid increasing the flow resistance of the water flow, or generate noise, and increase the maintenance cost of the baffle plate.

[0012] In one alternative embodiment, the inclined portion is an inclined surface; or,

[0013] The inclined part is a circular arc surface.

[0014] In one alternative embodiment, the wave deflector further includes:

[0015] The platform section and the inclined section are arranged sequentially in the direction of the center of the water tank.

[0016] Beneficial effects: The platform can protect the integrity of the water tank structure, prevent liquid from overflowing, improve the stability of the water tank, protect the equipment inside the water tank, and facilitate maintenance and cleaning.

[0017] Secondly, this utility model also provides a cooling fan, comprising:

[0018] The outer casing has an opening on one side wall;

[0019] A water tank is provided at the opening through an opening that can be pulled out. The opening of the water tank is provided with a wave deflector provided in the first aspect of this utility model. The opening has an upper edge. When the water tank is placed inside the opening, the wave deflector is located below the upper edge.

[0020] The water pipe passes through the gap between the upper edge and the baffle plate, and extends into the water tank along the inclined section.

[0021] Beneficial effects: The cooling fan of the second aspect of this utility model includes or uses the anti-surge plate of the first aspect of this utility model, and therefore has its beneficial effects, namely: it can effectively prevent the anti-surge plate from blocking the water pipe from entering the water tank 4, causing the water pipe to bend between the anti-surge plate and the outer shell. It overcomes the problem in the related technology that the anti-surge plate of the water tank is easy to squeeze the water pipe, affecting the smoothness and convenience of the water tank installation, resulting in insufficient water supply, affecting the performance of the cooling fan, and even potentially damaging the water pipe and causing safety hazards. It can make the water pipe run more smoothly and help improve the user experience.

[0022] In an optional embodiment, when the water tank is located inside the outer shell, its upper edge is located directly above the platform portion, the distance between the upper edge and the platform portion is d1, and the diameter of the water pipe is d2, where 2d2≤d1≤5d2.

[0023] Beneficial effect: When the ratio between d1 and d2 is within the above range, it can effectively prevent the baffle from blocking the water pipe from entering the water tank, causing the water pipe to bend between the baffle and the outer shell.

[0024] The platform section is designed to protect the integrity of the water tank structure, prevent liquid overflow, improve the stability of the water tank, protect the equipment inside the water tank, and facilitate maintenance and cleaning.

[0025] In one alternative embodiment, a mounting groove is formed on the wave deflector, and the water tank also includes a pump seat detachably connected to the mounting groove, the pump seat having a slope consistent with the inclination of the inclined portion.

[0026] Beneficial effects: The water pump base is used to install the water pump in the water tank. The upper surface of the water pump base has a slope, which can prevent the upper surface of the water pump base from blocking the water pipe from entering the water tank, causing the water pipe to bend between the baffle and the outer shell.

[0027] In an optional embodiment, the water tank further includes: a circulating water tank disposed on the baffle plate of the water tank, located below the wet curtain of the cooling fan, and the bottom of the circulating water tank has a connecting hole that communicates with the inner cavity of the water tank.

[0028] Beneficial effects: During operation, the water pump draws water from the tank and sprays it evenly onto the evaporative cooling pad through a distribution system. Hot outdoor air enters the evaporative cooling medium and exchanges heat with the water on the cooling pad, expelling the hot indoor air to the outside and achieving cooling. During this process, some water evaporates, while the remaining water drips into the circulating water tank and returns to the tank's interior through connecting holes, thus achieving water recycling.

[0029] In one alternative implementation, the cooling fan further includes:

[0030] The main body of the air duct is located inside the outer shell, and the air duct plate is detachably covered on the main body of the air duct, forming an air duct between the main body of the air duct and the air duct plate.

[0031] Beneficial effects: Air ducts can be used to guide and optimize airflow to improve the efficiency and performance of air coolers.

[0032] In one optional embodiment, the duct plate includes a duct plate body and an outlet pipe structure. The outlet pipe structure is used to guide the water pipe to the top of the water tank. One of the duct body and the outlet pipe structure is provided with a first limiting groove and a first engaging part, and the other of the duct body and the outlet pipe structure is provided with a first limiting protrusion and a second engaging part. When the first limiting protrusion is provided in the first limiting groove, the first engaging part can engage with the second engaging part.

[0033] Beneficial effects: With this setting, the operator can insert the first limiting protrusion into the first limiting groove. When the first limiting protrusion is installed in place, the first engaging part can engage with the second engaging part, thereby reliably limiting the outlet pipe structure on the air duct body. The installation process is simple and convenient.

[0034] In one optional embodiment, one of the air duct plate and the air duct body is provided with a second limiting groove and a third engaging part, and the other of the air duct plate and the air duct body is provided with a second limiting protrusion and a fourth engaging part. When the second limiting protrusion is provided in the second limiting groove, the third engaging part can engage with the fourth engaging part.

[0035] Beneficial effects: With this setting, the operator can insert the second limiting protrusion into the second limiting groove. After the second limiting protrusion is installed in place, the third engaging part can engage with the fourth engaging part, thereby reliably limiting the air duct plate on the air duct body. The installation process is simple and convenient. Attached Figure Description

[0063] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this utility model, not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.

[0064] The following is combined with Figures 1 to 17 The following describes embodiments of the present invention.

[0065] According to an embodiment of the present invention, a wave deflector 401 is provided for installation inside a water tank 4, the top of which has an opening 405. The wave deflector 401 includes a plate body 4013 and an inclined portion 4011.

[0066] Among them, such as Figure 1 and Figure 2As shown, the plate body 4013 is provided at the opening 405. The inclined portion 4011 is connected to the plate body 4013 and extends from top to bottom toward the middle of the water tank 4.

[0067] In use, the water pipe 5 of the cooling fan can be output from the outlet channel 201 and enter the water tank 4 through the gap between the baffle 401 and the upper edge of the outer casing 3 along the inclined part 4011. Since the inclined part 4011 can extend downward along the direction of the water pipe 5 entering the water tank 4, the inclined part 4011 can guide the water pipe 5 to extend into the water tank 4 at an incline and provide space for the extension of the water pipe 5.

[0068] Therefore, the anti-surge plate 401 of this utility model embodiment can effectively prevent the anti-surge plate 401 from blocking the water pipe 5 from entering the water tank 4, causing the water pipe 5 to bend between the anti-surge plate 401 and the upper edge of the outer shell 3. This overcomes the problem in related technologies where the anti-surge plate 401 of the water tank 4 is easily squeezed by the water pipe 5, affecting the smoothness and convenience of the installation of the water tank 4, resulting in insufficient water supply, affecting the performance of the cooling fan, and even potentially damaging the water pipe 5 and causing safety hazards. It can make the water pipe 5 run more smoothly and help improve the user experience. In one embodiment, the line connecting the beginning and end of the inclined part 4011 is defined as the first line, and the angle between the first line and the horizontal direction is θ1, where 30°≤θ1≤60°.

[0069] When θ1 is within the above range, the problem of the baffle plate 401 squeezing the water pipe 5 with the upper edge of the outer shell 3 after the water tank 4 is installed can be solved, and the structural stability of the baffle plate 401 will not be reduced, thus avoiding increased water flow resistance or noise, and increasing the maintenance cost of the baffle plate 401.

[0070] In one embodiment, the inclined portion 4011 is an inclined surface.

[0071] As a possible implementation, in an embodiment not shown in the accompanying drawings, the inclined portion 4011 is an arc surface.

[0072] As another alternative implementation, in an embodiment not shown in the accompanying drawings, the inclined portion 4011 may also be a stepped structure.

[0073] In one embodiment, the wave deflector 401 further includes a platform portion 4012. The platform portion 4012 and the inclined surface 4011 are arranged sequentially along the direction in which the water tank 4 enters the outer casing 3.

[0074] In one embodiment, such as Figure 3 As shown, the wave deflector 401 also includes a platform section 4012. The platform section 4012 and the inclined surface are arranged sequentially along the direction in which the water tank 4 enters the outer casing 3.

[0075] Platform 4012 can protect the structural integrity of water tank 4, prevent liquid from overflowing from water tank 4, improve the stability of water tank 4, protect the equipment inside water tank 4, and facilitate maintenance and cleaning.

[0076] According to an embodiment of the present invention, another aspect is also provided: a cooling fan, such as... Figure 5 , Figure 6 and Figure 7 As shown, the cooling fan includes a housing 3, a water tank 4, and a water pipe 5.

[0077] An opening 305 is provided on one side wall of the outer casing 3. The water tank 4 is removably mounted at the opening 305. A wave deflector 401 provided in the first aspect of this utility model is provided at the opening 405 of the water tank 4. The opening 305 has an upper edge, and when the water tank 4 is located inside the opening 305, the wave deflector 401 is located below the upper edge. A water pipe 5 passes through the gap between the upper edge and the wave deflector 401 and extends into the water tank 4 along the inclined portion 4011.

[0078] The cooling fan of the second aspect of this utility model includes or uses the anti-surge plate 401 of the first aspect of this utility model, and therefore has the beneficial effect of effectively preventing the anti-surge plate 401 from blocking the water pipe 5 from entering the water tank 4, causing the water pipe 5 to bend between the anti-surge plate 401 and the upper edge of the outer shell 3. This overcomes the problem in the related art that the anti-surge plate 401 of the water tank 4 is easy to squeeze the water pipe 5, affecting the smoothness and convenience of the installation of the water tank 4, resulting in insufficient water supply, affecting the performance of the cooling fan, and even potentially damaging the water pipe 5 and causing safety hazards. It can make the water pipe 5 run more smoothly and help improve the user experience.

[0079] In one embodiment, a water pump seat 403 is provided inside the water tank 4, and a water pump is provided on the water pump seat 403. One end of the water pipe 5 is connected to the water pump, and the other end passes through the air duct plate 100 and is connected to the drain outlet at the upper end of the air duct plate 100.

[0080] 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.

[0081] In one embodiment, the outer casing 3 has an upper edge, and when the water tank 4 is located inside the outer casing 3, the upper edge is located directly above the platform portion 4012, such as... Figure 1 and Figure 2 As shown, the distance between the upper edge and the platform part 4012 is d1, the diameter of the water pipe 5 is d2, and 2d2≤d1≤5d2.

[0082] When the ratio between d1 and d2 is within the above range, it can effectively prevent the baffle plate 401 from blocking the water pipe 5 from entering the water tank 4, causing the water pipe 5 to bend between the baffle plate 401 and the upper edge of the outer casing 3, making the water pipe 5 run more smoothly and helping to improve the user experience. In one embodiment, such as Figure 3 As shown, the water tank 4 includes a water tank body 402 and a wave deflector 401.

[0083] Preferably, the smaller the gap between the upper edge of the outer shell 3 and the baffle plate 401, the larger the inclination angle of the inclined surface of the baffle plate 401. The larger the inclination angle of the baffle plate 401 of the water tank 4, the easier it is for the water pipe 5 to fit snugly and smoothly into the interior of the water tank 4; the smaller the inclination angle, the easier it is for the baffle plate 401 to lift the water pipe 5, at which point a sufficiently large gap is needed to accommodate the lifted water pipe 5.

[0084] In an optional embodiment, for example, the distance between the wave deflector 401 and the upper edge of the housing 3 is 26.5 mm, and the tilt angle of the wave deflector 401 is set to 45°.

[0085] In one embodiment, a mounting groove 4014 is formed on the wave deflector 401, and the water tank 4 further includes a water pump seat 403 detachably connected to the mounting groove 4014, and a slope 4031 with the same inclination as the inclined portion 4011 is formed on the water pump seat 403.

[0086] The water pump base 403 is used to install the water pump in the water tank 4. An inclined portion 4011 is formed on the upper surface of the water pump base 403, which can prevent the upper surface of the water pump base 403 from blocking the water pipe 5 from entering the water tank 4, causing the water pipe 5 to bend between the anti-surge plate 401 and the upper edge of the outer casing 3.

[0087] In one embodiment, the water tank 4 further includes a circulating water tank 404. The circulating water tank 404 is disposed on the baffle plate 401 of the water tank 4, located below the wet curtain of the cooling fan, and a connecting hole is provided at the bottom of the circulating water tank 404, which is connected to the inner cavity of the water tank 4.

[0088] During operation, the water pump draws water from the water tank 4 and sprays it evenly onto the evaporative cooling pad through the water distribution system. Hot outdoor air enters the evaporative cooling medium and exchanges heat with the water at the evaporative cooling pad, allowing the hot indoor air to escape outdoors, thus achieving cooling. During this process, some water evaporates, while the remaining water drips into the circulating water tank 404 and returns to the inner cavity of the water tank 4 through the connecting holes, thus achieving water recycling.

[0089] In one embodiment, the air duct plate 100 of the air cooler includes an air duct plate body 1 and an outlet pipe structure 2. The outlet pipe structure 2 is used to guide the water pipe 5 to the top of the water tank 4 and includes a structural body. An outlet pipe channel 201 is formed in the structural body for the water pipe 5 to pass through. The outlet pipe channel 201 extends at least partially in the direction in which the water tank 4 is withdrawn from the device.

[0090] 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.

[0091] 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.

[0092] 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.

[0093] Although the device with water tank 4 and outlet pipe structure 2 in this application embodiment is a cooling fan, it is not limited to this. In some embodiments not shown in the drawings, the device with water tank 4 and outlet pipe structure 2 may also be a humidifier or the like.

[0094] In one embodiment, such as Figure 9 As shown, 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 θ2, where 20°≤θ2≤40°.

[0095] When θ2 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.

[0096] In one embodiment, the extension segment 2011 is an arc segment.

[0097] 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.

[0098] As a possible implementation, in an embodiment not shown in the accompanying drawings, the outlet channel 201 has a stepped structure, with the beginning of the extension section 2011 being the inlet end of the outlet channel 201 and the end of the extension section 2011 being the outlet end of the outlet channel 201. Exemplarily, the extension section 2011 includes a first segment and a second segment connected in sequence, the first segment extending vertically and the second segment extending horizontally.

[0099] As another alternative implementation, in an embodiment not shown in the accompanying drawings, the extension 2011 is inclined and tilted toward the direction in which the water tank 4 is drawn out of the device.

[0100] In one embodiment, such as Figure 9 , Figure 10 and Figure 11 As shown, extension segment 2011 is an arc segment. (As...) Figure 4 As shown, the central angle of the extension segment 2011 is θ3, where 40°≤θ3≤80°.

[0101] When the central angle of the extension section 2011 is within the above range, the water pipe 5 can be made to extend backward, which effectively solves the problem of the upper edge of the water tank 4 squeezing the water pipe 5 due to the downward extension 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.

[0102] In a preferred embodiment, the central angle of the extension 2011 is 50°.

[0103] In one embodiment, the outlet pipe structure 2 is located at the first side 303 of the device, and at least part of the outlet pipe channel 201 extends toward the second side 304 of the device from top to bottom, with the first side 303 and the second side 304 being arranged opposite to each other.

[0104] With this configuration, the guide section 2012 can change the direction of the water pipe 5 from extending backward to extending towards the second side 304 of the device, thereby facilitating the water pipe 5 to enter the water tank 4 through the anti-surge plate 401. This reduces the problem of the anti-surge plate 401 blocking the water pipe 5 from entering the water tank 4, causing the water pipe 5 to bend between the anti-surge plate 401 and the upper edge of the outer shell 3 of the device, resulting in the water pipe 5 being squeezed by the anti-surge plate 401 and the upper edge of the outer shell 3 after the water tank 4 is installed.

[0105] like Figure 10 and Figure 12 As shown, a guide section 2012 is formed on the outlet channel 201. The line connecting the beginning and end of the guide section 2012 is defined as the second line. In the direction from the first side 303 of the device to the second side 304, the angle between the second line and the vertical direction is θ4, where 15°≤θ4≤30°.

[0106] When θ4 is within the above range, it is easy for the water pipe 5 to enter the water tank 4 through the baffle plate 401, and the water pipe 5 will not be damaged or the flow resistance of the liquid will be increased due to excessive bending.

[0107] In one embodiment, such as Figure 10 and Figure 12 As shown, the guide segment 2012 is an arc segment. In a 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 θ5, 30°≤θ5≤60°.

[0108] When the central angle of the guide section 2012 is within the above range, it is easy for the water pipe 5 to enter the water tank 4 through the anti-surge plate 401, and the water pipe 5 will not be damaged or the flow resistance of the liquid will be increased due to excessive bending.

[0109] The arc-shaped guide section 2012 helps reduce wear and damage to the water pipe 5 and makes the water flow more smoothly within the water pipe 5.

[0110] Although in such Figure 9 and Figure 10 In the illustrated embodiment, the lower part of the extension segment 2011 forms a guide segment 2012, but the embodiments of this application are not limited to this. The extension segment 2011 and the guide segment 2012 may also be formed at the same position in the outlet channel 201; or the extension segment 2011 and the guide segment 2012 may be alternately arranged along the extension direction of the outlet channel 201; or the extension segment 2011 may be formed on at least one of the upper and lower parts of the guide segment 2012. All of the above embodiments fall within the scope of protection claimed by this utility model.

[0111] As a possible implementation, in an embodiment not shown in the accompanying drawings, the guide segment 2012 has a stepped structure, with the beginning of the guide segment 2012 being the inlet end of the outlet channel 201 and the end end of the guide segment 2012 being the outlet end of the outlet channel 201. Exemplarily, in an optional implementation, the guide segment 2012 includes a first segment and a second segment connected in sequence, the first segment extending vertically and the second segment extending horizontally.

[0112] As another alternative implementation, in an embodiment not shown in the accompanying drawings, the guide segment 2012 is tilted.

[0113] In a preferred embodiment, such as Figure 12 As shown, θ5 = 45°.

[0114] In a preferred embodiment, the duct plate 100 further includes reinforcing ribs 2015 disposed on the inner wall of the outlet pipe channel 201.

[0115] The reinforcing rib 2015 can enhance the structural strength of the outlet pipe structure 2, and prevent the outlet pipe structure 2 from deforming, which would affect the guiding effect of the outlet pipe structure 2 on the water pipe 5, or even squeeze the water pipe 5.

[0116] In a preferred embodiment, the outlet pipe structure 2 has a first sidewall 2013 and a second sidewall 2014 arranged opposite to each other. The first sidewall 2013 and the second sidewall 2014 are arranged sequentially along the direction of the second side 304 of the approach device. The reinforcing rib 2015 includes a first reinforcing rib 20151 and a second reinforcing rib 20152.

[0117] Among them, such as Figure 12 As shown, there are at least two first reinforcing ribs 20151, which are vertically spaced on the first sidewall 2013. There are at least two second reinforcing ribs 20152, which are vertically spaced on the second sidewall 2014, with the lowermost second reinforcing rib 20152 positioned above the lowermost first reinforcing rib 20151.

[0118] In this embodiment, the air duct plate 100 is configured such that the first reinforcing member and the second reinforcing rib 20152 are spaced apart in the vertical direction, thereby reducing the influence of the first reinforcing rib 20151 and the second reinforcing rib 20152 on the inner diameter of the second extension section 2011. Furthermore, the second reinforcing rib 20152 is positioned above the first reinforcing rib 20151, which further prevents the water pipe 5 from tilting downwards or in the first direction, increases the angle at which the water pipe 5 exits to the second side 304, and prevents the baffle plate 401 from pressing against the upper edge of the outer casing 3, thus making the water pipe 5 flow more smoothly.

[0119] In the embodiments of this application, it should be noted that, although in Figure 5In the figure, 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", "rear", etc. indicate the orientation or positional relationship based on the orientation or positional relationship shown in the figure. They are only for the convenience of describing this application and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this application.

[0120] In one embodiment, the distance between the first reinforcing rib 20151 and the second reinforcing rib 20152 in the vertical direction is 5.3mm, which can further reduce the possibility of the water pipe 5 tilting towards the first side 303 position of the cooling fan and increase the angle of the water pipe 5 exiting towards the second side 304 of the device, so as to avoid the baffle plate 401 and the upper edge of the outer shell 3 squeezing the water pipe 5, making the water pipe 5 run more smoothly.

[0121] In one embodiment, a water pump seat 403 is provided inside the water tank 4, and a water pump is provided on the water pump seat 403. One end of the water pipe 5 is connected to the water pump, and the other end passes through the air duct plate 100 and is connected to the drain outlet at the upper end of the air duct plate 100.

[0122] 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.

[0123] In one embodiment, the air cooler also includes a duct body 6. The duct body 6 is disposed inside the housing 3, and the duct plate 100 is detachably covered on the duct body 6, forming an air duct between the duct body 6 and the duct plate 100.

[0124] Air ducts can be used to guide and optimize airflow to improve the efficiency and performance of air coolers.

[0125] In one embodiment, a first limiting groove 202 is provided on either the duct body 6 or the outlet pipe structure 2 (see...). Figure 10 ) and the first card combination 203 (see Figure 9 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 engaging part 602 (see...). Figure 13 When the first limiting protrusion 601 is provided in the first limiting groove 202, the first engaging part 203 can engage with the second engaging part 602.

[0126] With this setup, the operator can insert the first limiting protrusion 601 into the first limiting groove 202. Once the first limiting protrusion 601 is in place, the first engaging part 203 can engage with the second engaging part 602, thereby reliably limiting the outlet pipe structure 2 onto the air duct body 6. The installation process is simple and convenient.

[0127] In one embodiment, one of the air duct plate 100 and the air duct body 6 is provided with a second limiting groove 101 and a third engaging portion 102 (see...). Figure 17 The other of the air duct plate 100 and the air duct body 6 is provided with a second limiting protrusion 603 and a fourth engaging part 604 (see...). Figure 15 When the second limiting protrusion 603 is provided in the second limiting groove 101, the third engaging part 102 can engage with the fourth engaging part 604.

[0128] With this configuration, the operator can insert the second limiting protrusion 603 into the second limiting groove 101. After the second limiting protrusion 603 is installed in place, the third engaging part 102 can engage with the fourth engaging part 604, thereby reliably limiting the air duct plate 100 on the air duct body 6. The installation process is simple and convenient.

[0129] In one embodiment, such as Figure 7 As shown, the outer casing 3 includes a front casing 301 and a rear casing 302, as... Figure 14 and Figure 16 As shown, one of the front shell 301 and the rear shell 302 is provided with a connecting post 3011, and 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 post through hole 605, which allows the connecting post 3011 to rotate. The cooling fan also includes a fastener, which can pass through the connecting post 3011 and the connecting hole 3022 and connect the front shell 301, the air duct body 6 and the rear shell 302.

[0130] In one embodiment, the duct plate body 1 of the duct plate 100 and the outlet pipe structure 2 are integrally formed.

[0131] In summary, the air duct plate 100 for the air cooler of the first aspect of this utility model and the air cooler of the second aspect can overcome the problem that the upper edge of the water tank 4 of the air cooler in the prior art is prone to interference with the water pipe 5. This not only affects the smoothness and convenience of the installation of the water tank 4 and the user experience, but also causes compression of the water pipe 5, resulting in insufficient water supply, affecting the performance of the air cooler, and may even cause the water pipe 5 to be damaged and leak, thereby affecting the normal use of the air cooler and causing safety hazards.

[0132] Although embodiments of the present invention have been described in conjunction with the accompanying drawings, those skilled in the art can make various modifications and variations without departing from the spirit and scope of the present invention, and all such modifications and variations fall within the scope of protection claimed by the present invention.
