Description

Technical Field

[0001] This application belongs to the field of fan technology, specifically relating to fans. Background Technology

[0002] Fans typically achieve ventilation and cooling by blowing air outwards to accelerate airflow. However, in hot environments, the air blown out by fans is also hot, resulting in a weak cooling effect that fails to meet user needs. Utility Model Content

[0003] In view of this, this application provides a fan, the fan comprising:

[0004] A water tank module includes a housing assembly, an atomizer, and a flow guide. The housing assembly has a water storage space and a first mist outlet channel communicating with the water storage space. The atomizer is disposed in the housing assembly and is used to atomize the water in the water storage space into water mist and spray it upward. The flow guide is disposed in the housing assembly and has a through hole. The upward sprayed water column can pass through the through hole and fall onto the flow guide, and then fall back into the water storage space from the outer periphery of the flow guide.

[0005] An air outlet module, comprising a cover and an air outlet device, wherein the air outlet device is disposed within the cover, and the cover is provided with a mist outlet that communicates with the first mist outlet channel.

[0006] Based on this, the guide includes a platform and a first bend that bends to connect the platform. The platform is provided with a through hole. After the water column passes through the through hole and falls onto the upper surface of the platform, it can fall back into the water storage space along the first bend.

[0007] Based on this, the first bend abuts against the inner wall of the housing assembly, and the platform and the first bend are provided with holes, so that water falling onto the platform can fall along the inner wall of the holes.

[0008] Based on this, the hole is set in direct correspondence with the through hole.

[0009] Based on this, the atomizing surface of the atomizer is inclined toward the direction of the hole.

[0010] Based on this, there is a gap between the side of the platform perpendicular to the bend connection and the inner wall of the housing assembly.

[0011] Based on this, the housing assembly includes a column, and a vertically arranged partition is provided inside the column to divide the inside of the column into a first receiving space and a second receiving space arranged horizontally. The partition has a connecting hole at the end away from the air outlet module that connects the first receiving space and the second receiving space. The air guide is disposed in the first receiving space. The water tank module also includes a blower, which is disposed in the second receiving space and blows air in a direction away from the air outlet module.

[0012] Based on this, the guide includes a platform and a second bent portion that bends and connects the platform. The second bent portion abuts against the partition, and there is a gap between the second bent portion and the edge of the partition.

[0013] Based on this, the flow guide includes a platform and a first bent portion and a second bent portion that bend and connect the platform, with the first bent portion and the second bent portion being disposed opposite to each other; the flow guide also includes a first connecting portion and a second connecting portion, with the first connecting portion connected to the inner side of the platform and the inner side of the first bent portion, and the second connecting portion connected to the inner side of the platform and the inner side of the second bent portion.

[0014] Based on this, the fan also includes a pitch module, one end of which is connected to the housing assembly, and the pitch module has a second mist outlet channel that connects to the first mist outlet channel; the air outlet module also includes a mist outlet pipe, the cover is connected to the other end of the pitch module, one end of the mist outlet pipe is connected to the cover, the other end is connected to the pitch module, and the mist outlet pipe has a third mist outlet channel that connects the second mist outlet channel and the mist outlet.

[0015] The water mist can be discharged from the mist outlet through the first mist outlet channel, the second mist outlet channel, and the third mist outlet channel in sequence.

[0016] The fan provided in this application, firstly, utilizes the atomizer in the water tank module to atomize water into mist, which is then discharged from the mist outlet. The airflow from the exhaust device then carries the mist to a greater distance, achieving cooling. This improves the cooling effect compared to a standalone exhaust device. Secondly, when the atomizer sprays water upwards, it also forms a water column. If this water column falls back down, it can affect the subsequent misting process, reducing the mist output. Therefore, this application adds a guide component within the housing assembly. The guide component has through holes, allowing both the upward-spraying water column and mist to pass through, ensuring normal flow of the mist within the misting channel. Furthermore, when the water column falls back down, at least part of it lands on the guide component and then falls back down from its outer periphery into the water storage space. In other words, this application changes the path of the falling water column, preventing it from falling back down and reducing or even eliminating its impact on subsequent misting, thereby increasing the mist output.

[0017] In summary, the fan provided in this application improves the cooling effect by combining water mist with airflow, and the design of the airflow guide can increase the amount of mist output. Attached Figure Description

Detailed Implementation

[0034] The following are preferred embodiments of this application. It should be noted that, for those skilled in the art, several improvements and modifications can be made without departing from the principles of this application, and these improvements and modifications are also considered to be within the scope of protection of this application.

[0035] In view of this, in order to solve the above-mentioned technical problems, this application provides a fan, which please refer to. Figures 1-4 , Figure 1 This is a three-dimensional structural diagram of the fan in one embodiment of this application. Figure 2 for Figure 1 The diagram shows a three-dimensional structure of the fan from another perspective. Figure 3 for Figure 1 The exploded view of the fan shown. Figure 4 for Figure 1The diagram shows a cross-sectional view of a fan. This embodiment provides a fan 1, which includes a water tank module 10 and an air outlet module 30. The water tank module 10 includes a housing assembly 11, an atomizer 12, and a guide member 17. The housing assembly 11 has a water storage space 111 and a first mist outlet channel 110 communicating with the water storage space 111. The atomizer 12 is disposed in the housing assembly 11 and is used to atomize the water in the water storage space 111 into water mist and spray it upward. The guide member 17 is disposed in the housing assembly 11 and has a through hole 170. The upward sprayed water column can pass through the through hole 170 and fall onto the guide member 17, and then fall back from the outer periphery of the guide member 17 into the water storage space 111. The air outlet module 30 includes a cover 31 and an air outlet device 32. The air outlet device 32 is disposed inside the cover 31. The cover 31 is provided with a mist outlet 310 that communicates with the first mist outlet channel 110.

[0036] The fan 1 provided in this embodiment includes, but is not limited to, household fans and industrial fans in terms of usage scenarios, and includes, but is not limited to, desktop fans and standing fans in terms of type. This embodiment only uses a household desktop fan as an example for illustration.

[0037] The water tank module 10 mainly serves as the main body of the fan 1 and provides water mist. The water tank module 10 consists of a housing assembly 11 and an atomizer 12. The housing assembly 11 is composed of multiple parts, the specific structure of which will be described in detail below. The housing assembly 11 may contain a water storage space 111 and a first mist outlet channel 110. The water storage space 111 stores water, and the atomizer 12 can be mounted on the housing assembly 11. When working, the atomizer 12 atomizes the water in the water storage space 111 into water mist. Since the first mist outlet channel 110 connects to the water storage space 111, water mist can enter the first mist outlet channel 110.

[0038] The air outlet module 30 is mainly used for air and mist output. It consists of a cover 31 and an air outlet device 32. The cover 31 forms the outer shell of the air outlet module 30 and has an air inlet and an air outlet. The specific structure of the cover 31 will not be described in detail in this embodiment. The air outlet device 32 is mainly used for air output. It includes, but is not limited to, axial flow air outlet devices and inertial flow air outlet devices. This embodiment only uses an axial flow air outlet device for illustrative purposes; the specific structure of the air outlet device 32 will not be described in detail here. The air outlet device 32 can be installed inside the cover 31, thus protecting it. The cover 31 can be provided with a mist outlet 310 for outputting water mist, and this mist outlet 310 is connected to the first mist outlet channel 110. Therefore, water mist can be discharged from the mist outlet 310 through the first mist outlet channel 110. Furthermore, the water mist after being discharged can drift further away under the influence of the air blown out by the air outlet device 32. The water mist can absorb heat during the evaporation process, thereby reducing the ambient temperature and achieving the cooling effect. Compared with the standalone air outlet device 32, it can improve the cooling effect.

[0039] When the atomizer 12 atomizes water mist, the mist is sprayed upwards, meaning it sprays towards the air outlet module 30. Simultaneously, the formation of the water mist also generates vibrations, creating an upward-spraying water column. The water mist travels upwards along the mist outlet channel and eventually exits through the mist outlet 310, but the water column does not. After reaching its highest point, the water column falls back down. When the water column falls, it interferes with the formed water mist, affecting the subsequent mist output process and thus reducing the amount of mist produced.

[0040] To address the aforementioned issues, this embodiment adds a flow guide 17 within the water tank module 10. The flow guide 17 can be housed within the housing assembly 11, and a through hole 170 can be formed on the flow guide 17. The upward-sprayed water mist can pass through the through hole 170, ensuring normal flow of the water mist within the mist outlet channel. The water column can also pass through the through hole 170. When the water column falls back, at least a portion of the water column can fall onto the upper surface of the flow guide 17, or the entire water column can fall onto the upper surface of the flow guide 17. The upper surface of the flow guide 17 is the surface of the flow guide 17 closest to the air outlet module 30. Because the water experiences a certain impact when falling onto the upper surface of the flow guide 17, the water flows outwards, causing it to fall from the outer periphery of the flow guide 17 and then back into the water storage space 111. In other words, this implementation method changes the path of the water column's fall, preventing it from falling back along the same route, thus reducing or even eliminating the impact of the water column on subsequent fog production and increasing the amount of fog produced.

[0041] In summary, the fan 1 provided in this embodiment improves the cooling effect by combining water mist with airflow, and the airflow guide 17 can increase the amount of mist output.

[0042] Optionally, in addition to the above-mentioned modules, the fan 1 may also include a base module 40. The base module 40 is located on the side of the water tank module 10 away from the air outlet module 30, that is, the base module 40 is located below the water tank module 10 and is used to support the entire fan 1.

[0043] Alternatively, a rotating device 41 may be provided on the base module 40. The rotating device 41 is connected to the water tank module 10. The rotating device 41 is used to make the water tank module 10, as well as the pitch module 20 and the air outlet module 30, rotate in the circumferential direction. At this time, the fan 1 has a horizontal oscillation function.

[0044] Please refer to this as well. Figures 5-6 , Figure 5 This is a three-dimensional structural diagram of the guide member in one embodiment of this application. Figure 6 for Figure 5 The diagram shows a three-dimensional structural schematic of the guide component from another perspective. In this embodiment, the guide component 17 includes a platform 171 and a first bent portion 172 that bends and connects to the platform 171. The platform 171 is provided with the through hole 170. After the water column passes through the through hole 170 and falls onto the upper surface of the platform 171, it can fall back into the water storage space 111 along the first bent portion 172.

[0045] The guide member 17 may include a platform 171 and a first bend 172, wherein the platform 171 has a straight structure and can be horizontally arranged, and the first bend 172 is bent and connected to the periphery of the platform 171. In this embodiment, the aforementioned through hole 170 can be opened on the platform 171. When the water column passes through the through hole 170, it will fall to the upper surface of the platform 171, and then fall back down along the first bend 172 into the water storage space 111. Therefore, by setting the first bend 172, water can be guided back into the water storage space 111, avoiding the dripping sound caused by water falling directly from the platform 171 at a high position into the water storage space 111.

[0046] Optionally, the position of the hole 1720 on the platform 171 is related to the position of the atomizer 12 and the water column, and can be adjusted according to the actual situation.

[0047] Please refer to this as well. Figures 5-7 , Figure 7 This is a schematic diagram showing the flow guide and the column of the housing assembly cooperating in one embodiment of this application. In this embodiment, the first bent portion 172 abuts against the inner wall of the housing assembly 11, and the platform 171 and the first bent portion 172 are provided with holes 1720, so that water falling onto the platform 171 can fall along the inner wall of the holes 1720.

[0048] The first bend 172 can abut against the inner wall of the housing assembly 11, thereby improving the stability of the guide 17. Furthermore, in this embodiment, holes 1720 can be formed in the platform 171 and the first bend 172, allowing water falling onto the platform 171 to fall along the inner wall of the holes 1720. This avoids the problem of the first bend 172 abutting against the inner wall of the housing assembly 11, which would affect the water's descent, thus increasing the water's descent speed, reducing circulation time, and increasing circulation speed.

[0049] Please refer to this as well. Figures 5-6 ,as well as Figure 8 , Figure 8 for Figure 5 The diagram shows a top view of the flow guide. In this embodiment, the hole 1720 is positioned directly opposite the through hole 170. By positioning the hole 1720 directly opposite the through hole 170, the distance between the through hole 170 and the hole 1720 can be reduced, allowing water falling onto the platform 171 to flow more quickly to the hole 1720 and then fall from the inner wall of the hole 1720, further increasing the speed of water descent, reducing circulation time, and increasing circulation speed.

[0050] Please refer to Figure 9 , Figure 9 This is a cross-sectional schematic diagram of the atomizer, the column in the housing assembly, and the flow guide in one embodiment of this application. In this embodiment, the atomizing surface 120 of the atomizer 12 is inclined toward the orifice 1720. In related technologies, the atomizing surface 120 of the atomizer 12 is usually horizontally arranged, so the water column is sprayed vertically upward. In this embodiment, the atomizing surface 120 is inclined, so that each water column formed is sprayed upward at an angle. Because the water column is sprayed upward at an angle, it is easier for the water column to fall onto the upper surface of the flow guide 17 after passing through the through hole 170. Secondly, by tilting the atomizing surface 120 toward the orifice 1720, the water column falls onto the flow guide 17 and is closer to the orifice 1720, further increasing the speed of water falling, reducing circulation time, and increasing circulation speed.

[0051] Please refer to Figure 10 , Figure 10 for Figure 7 The diagram shows a cross-sectional view of the guide member engaging with the column of the housing assembly. In this embodiment, there is a gap between the side of the platform 171 perpendicular to the bent connection and the inner wall of the housing assembly 11.

[0052] Based on the first bend 172 and the hole 1720, this embodiment also allows for a gap between the side of the platform 171 perpendicular to the bend and the inner wall of the housing assembly 11. In other words, one side of the platform 171 is used to bend and connect the first bend 172, and a certain gap is left between the side of the platform 171 perpendicular to the first bend 172 and the inner wall of the housing assembly 11, so that water falling onto the platform 171 can fall not only from the first bend 172, but also from the edge of the platform 171, further increasing the speed of water falling, reducing circulation time, and increasing circulation speed.

[0053] Please refer to this as well. Figures 11-13 , Figure 11 This is a three-dimensional structural diagram of the column in one embodiment of this application. Figure 12 for Figure 11 A three-dimensional structural diagram of the column from another perspective. Figure 13 This is a three-dimensional cross-sectional view of the column, guide member, and blower device according to one embodiment of this application. In this embodiment, the housing assembly 11 includes a column 15, and a vertically arranged partition 150 is provided inside the column 15 to divide the column 15 into a horizontally arranged first receiving space 151 and a second receiving space 152. The partition 150 has a connecting hole 153 at one end away from the air outlet module 30, which connects the first receiving space 151 and the second receiving space 152. The guide member 17 is disposed in the first receiving space 151. The water tank module 10 also includes a blower device 16, which is disposed in the second receiving space 152 and blows air in a direction away from the air outlet module 30.

[0054] The housing assembly 11 may include a column 15 and an outer shell. A vertically arranged partition 150 is provided inside the column 15, thereby dividing the interior of the column 15 into two receiving spaces: a first receiving space 151 and a second receiving space 152, which are arranged horizontally. Furthermore, a connecting hole 153 may be provided at the lower end of the partition 150 away from the air outlet module 30, through which the first receiving space 151 and the second receiving space 152 can be connected.

[0055] The aforementioned guide member 17 can be disposed within the first receiving space 151, and a portion of the water storage space 111 can also be disposed within the first receiving space 151. The atomizer 12 is also disposed corresponding to the first receiving space 151, and the first mist outlet channel 110 is also disposed within the first receiving space 151. Therefore, the atomizer 12 atomizes the water in the first receiving space 151 into water mist, which is then transmitted through the guide member 17 along the first mist outlet channel 110 within the first receiving space 151.

[0056] The second receiving space 152 may be equipped with a blowing device 16, which is a fan 1 that blows air downwards in a direction away from the air outlet module 30. In related technologies, if the atomizer 12 does not have the blowing device 16 during atomization, the water mist will diffuse within the first receiving space 151 and move slowly towards the mist outlet 310, or even not move at all. With the blowing device 16 installed, the air blown by the blowing device 16 can carry the water mist upwards. However, when the air moves downwards through the second receiving space 152, because there is water below, the air will move through the connecting hole 153 to the first receiving space 151 and be transported upwards along the inner wall of the first receiving space 151, i.e., the inner wall of the column 15. As a result, the air can only carry away the water mist at the edges and transport it upwards, while the water mist in the center cannot be transported upwards, resulting in a small amount of mist output.

[0057] However, in this embodiment, by adding a flow guide 17 and opening a through hole 170 on the flow guide 17, the wind can be transmitted upward through the through hole 170 after entering the first receiving space 151. Therefore, the wind will travel through more paths in this process and will carry a large amount of water mist upward. The amount of water mist is much greater than that at the edge, thus increasing the final amount of mist output.

[0058] Please refer to this again. Figures 5-6 , Figure 10 ,as well as Figure 13 In this embodiment, the guide member 17 includes a platform 171 and a second bent portion 173 that bends and connects the platform 171. The second bent portion 173 abuts against the partition 150, and there is a gap between the second bent portion 173 and the edge of the partition 150.

[0059] The airflow guide 17 may include a platform 171 and a second bend 173. The second bend 173 is also bent and connected to the edge of the platform 171, and may be disposed opposite to the first bend 172. In this embodiment, the second bend 173 abuts against the partition 150, and the second bend 173 and the platform 171 close the partition 150, which not only improves stability but also prevents air from being transmitted upward from the edge. Similarly, the first bend 172 may also abut against the inner wall of the column 15, thereby preventing air from being transmitted upward from the other edge, allowing more air to be transmitted upward from the through hole 170, further increasing the mist output. In addition, in this embodiment, there may be a gap between the second bend 173 and the edge of the partition 150, preventing the second bend 173 from exceeding the edge of the partition 150 during assembly, thereby blocking the connecting hole 153. This ensures a larger air intake, allowing more air to enter the first receiving space 151 through the connecting hole 153.

[0060] Please refer to this again. Figures 5-6In this embodiment, the flow guide 17 includes a platform 171 and a first bent portion 172 and a second bent portion 173 that bend and connect the platform 171. The first bent portion 172 and the second bent portion 173 are disposed opposite to each other. The flow guide 17 also includes a first connecting portion 174 and a second connecting portion 175. The first connecting portion 174 is connected to the inner side of the platform 171 and the inner side of the first bent portion 172, and the second connecting portion 175 is connected to the inner side of the platform 171 and the inner side of the second bent portion 173.

[0061] The platform 171, the first bend 172, and the second bend 173 of the flow guide 17 have been described in detail above, and will not be repeated here. Based on this, a first connecting portion 174 and a second connecting portion 175 can be added. The first connecting portion 174 connects the inner side of the platform 171 to the inner side of the first bend 172, and the second connecting portion 175 connects the inner side of the platform 171 to the inner side of the second bend 173. The first connecting portion 174 and the second connecting portion 175 can act as reinforcing ribs, improving the connection performance between the platform 171 and the first bend 172 and the second bend 173, and improving the overall strength of the flow guide 17.

[0062] Please refer to this again. Figures 1-4 In this embodiment, the fan 1 further includes a pitch module 20, one end of which is connected to the housing assembly 11. The pitch module 20 has a second mist outlet channel 200 that communicates with the first mist outlet channel 110. The air outlet module 30 further includes a mist outlet pipe 33. The cover 31 is connected to the other end of the pitch module 20. One end of the mist outlet pipe 33 is connected to the cover 31, and the other end is connected to the pitch module 20. The mist outlet pipe 33 has a third mist outlet channel 330 that communicates with the second mist outlet channel 200 and the mist outlet 310. The water mist can be discharged from the mist outlet 310 in sequence through the first mist outlet channel 110, the second mist outlet channel 200, and the third mist outlet channel 330.

[0063] In summary, through the above methods and actual product testing, this application can increase the fog output by 20%-30%, achieving a significant increase in fog volume.

[0064] In addition to the aforementioned modules, fan 1 may also include a pitch module 20. The pitch module 20 is mainly used to achieve the pitch function. One end of the pitch module 20 is connected to the housing assembly 11, and the pitch module 20 has a second mist outlet channel 200 that connects to the first mist outlet channel 110. Therefore, water mist can enter the second mist outlet channel 200 through the first mist outlet channel 110. The cover 31 of the air outlet module 30 can be connected to the other end of the pitch module 20. Thus, when the pitch module 20 pitches, it can drive the cover 31 to pitch, thereby driving the air outlet module 30 to pitch.

[0065] The air outlet module 30 may also include a mist outlet pipe 33, which is mainly used to provide a mist outlet channel for water mist. A mist outlet 310 for water mist can be provided on the cover 31. One end of the mist outlet pipe 33 is connected to the cover 31, and the other end is connected to the pitch module 20. The mist outlet pipe 33 has a third mist outlet channel 330 inside, which can connect one end of the third mist outlet channel 330 to the second mist outlet channel 200 and the other end to the mist outlet 310. Thus, through the cooperation of the water tank module 10, the pitch module 20, the mist outlet pipe 33, and the cover 31, the first mist outlet channel 110, the second mist outlet channel 200, the third mist outlet channel 330, and the mist outlet 310 are connected together.

[0066] The first mist outlet channel 110, the second mist outlet channel 200, and the third mist outlet channel 330 together constitute the mist outlet channel. The water in the water storage space 111 is atomized into water mist by the atomizer 12 and can pass through the first mist outlet channel 110, the second mist outlet channel 200, and the third mist outlet channel 330 in sequence, and finally be discharged from the mist outlet 310.

[0067] In related technologies, the mist outlet pipe 33 is usually connected to the water tank module 10. In this case, the structure of the mist outlet pipe 33 is complex, and the fan 1 usually does not have a pitch function. Even if the fan 1 does have a pitch function, the mist outlet pipe 33 may obstruct the pitching process. However, in this embodiment, the pitch module 20 can act as part of the mist outlet channel, that is, the pitch module 20 acts as the second mist outlet channel 200 in the mist outlet channel. The pitch module 20 is used to connect the first mist outlet channel 110 in the water tank module 10 and the third mist outlet channel 330 in the mist outlet pipe 33. This not only simplifies the structure of the mist outlet pipe 33, but also allows the pitch module 20 to drive the mist outlet pipe 33 to move synchronously during the pitching process, so the mist outlet channel is not affected by the pitching process. Optionally, the mist outlet pipe 33 can be located inside the cover 31.

[0068] In summary, the fan 1 provided in this embodiment improves the cooling effect by combining water mist with airflow. The built-in mist outlet pipe 33 improves the appearance. The pitch module 20 can also serve as a partial mist outlet channel in addition to realizing the pitch function. At this time, the fan 1 can also be called a desktop cooling fan.
