[0069] It should be noted that, unless otherwise specified, the embodiments and features described in this application can be combined with each other. The preferred embodiments of this application will now be described in detail with reference to the accompanying drawings.

[0070] This application provides a spray fan 100, as shown in Figures 1-4. The spray fan 100 includes a liquid storage tank 10, a telescopic rod 11, a fan body 12, a spray head 13, and a pump body 14. The liquid storage tank 10 includes a bottom wall 101 and a side wall 102 surrounding the bottom wall 101, forming a liquid storage space 103 for storing a solution. The telescopic rod 11 includes a first end 111 and a second end 112 disposed opposite to each other, with the first end 111 connected to the liquid storage tank 10. The fan body 12 is connected to the second end 112 so that the fan body 12 can be retracted into the liquid storage space 103 via the telescopic rod 11, which is a first retracted state. The spray head 13 is disposed on the fan body 12. The pump body 14 communicates with the liquid storage space 103 and the spray head 13 to drive the solution in the liquid storage space 103 to flow to the spray head 13.

[0071] Firstly, the spray fan 100 shown in this embodiment has a superior cooling effect compared to ordinary fans. This is because the spray fan 100 shown in this application has a spray head 13 on the fan body 12. The spray head 13 is connected to the liquid storage space 103 of the liquid storage tank 10 through the pump body 14. When the pump body 14 is running, it can transport the solution in the liquid storage space 103 to the spray head 13 for atomization and spraying. This allows the wind blown out by the fan body 12 to mix with the solution. The solution absorbs heat during the evaporation process, so it can provide a better cooling effect compared to ordinary fans.

[0072] Secondly, the spray fan 100 shown in this embodiment is easier to store than the spray fans in the prior art. This is because the spray fans in the prior art are bulky and cannot change their size through their own structure, so they are not easy to store. In this embodiment, the fan body 12 is connected to the liquid storage tank 10 by a telescopic rod 11. The fan body 12 can be retracted into the liquid storage space 103 by the telescopic rod 11, thereby reducing the size of the spray fan 100 and achieving the technical effect of easy storage.

[0073] Thirdly, the misting fan 100 shown in this embodiment has higher adaptability compared to misting fans in the prior art. This is because different users have different requirements for the air outlet height of the fan body 12. For example, among fishing users, shorter users or those who choose lower seats usually need a lower air outlet height, while taller users or those who choose higher seats usually need a higher air outlet height. In existing misting fans, the air outlet height of the fan body 12 cannot be adjusted, which cannot meet the usage needs of different users, so its adaptability is relatively poor. However, the fan body 12 of this embodiment can be adjusted in height via the telescopic rod 11, which can better meet the needs of different users, so its adaptability is better.

[0074] This application embodiment also provides a spray fan 100, as shown in Figures 5-7. The spray fan 100 includes a liquid storage tank 10, a telescopic rod 11, a fan body 12, a spray head 13, and a pump body 14. The liquid storage tank 10 includes a bottom wall 101 and a side wall 102 surrounding the bottom wall 101, forming a liquid storage space 103 for storing a solution. The telescopic rod 11 includes a first end 111 and a second end 112 disposed opposite to each other, with the first end 111 connected to the liquid storage tank 10. The fan body 12 is rotatably connected to the second end 112, allowing the fan body 12 to move towards the liquid storage space 103 using the telescopic rod 11, and allowing the fan body 12 to be rotated to cover the outside 104 of the liquid storage tank, forming a second retracted state. The spray head 13 is disposed on the fan body 12. The pump body 14 is connected to the liquid storage space 103 and the spray head 13 to drive the solution in the liquid storage space 103 to flow to the spray head 13.

[0075] Firstly, the spray fan 100 shown in this application has a spray head 13, which is disposed on the fan body 12. The spray head 13 is connected to the liquid storage space 103 of the liquid storage tank 10 via the pump body 14. When the pump body 14 is running, it can transport the solution in the liquid storage space 103 to the spray head 13 for atomization and spraying, so that the wind blown out by the fan body 12 is mixed with the solution. The solution absorbs heat during the evaporation process. Therefore, the spray fan 100 shown in this application can provide a better cooling effect than ordinary fans.

[0076] Secondly, existing spray fans are bulky and cannot change their size through their own structure, making them inconvenient to store. In this embodiment, the fan body 12 is connected to the liquid storage tank 10 via a telescopic rod 11, so the fan body 12 can move towards the liquid storage space 103 via the telescopic rod 11. Furthermore, since the fan body 12 and the telescopic rod 11 are rotatably connected, the fan body 12 can also be rotated to cover the outside 104 of the liquid storage tank. Thus, it can be seen that the spray fan 100 shown in this embodiment can reduce the size of the spray fan 100 by adjusting the height and pitch angle of the fan body 12, thereby achieving the technical effects of easy storage and increased aesthetics.

[0077] Thirdly, different users have different requirements for the air outlet height of the fan body 12. For example, among fishing users, shorter users or those who choose lower seats usually need a lower air outlet height, while taller users or those who choose higher seats usually need a higher air outlet height. In existing misting fans, the air outlet height of the fan body 12 cannot be adjusted, which cannot meet the usage needs of different users, resulting in poor adaptability. However, the fan body 12 in this embodiment can be adjusted in height via the telescopic rod 11, which can better meet the needs of different users, thus providing better adaptability.

[0078] Referring to Figures 1-3, in some embodiments, in the first storage state, the fan body 12 is rotatably connected to the second end 112 to adjust the pitch angle of the fan body 12 so that the fan body 12 can rotate to the position that is blocked at the opening 105 of the liquid storage tank.

[0079] Specifically, since the fan body 12 is rotatably connected to the second end 112, the height of the fan body 12 can be reduced by adjusting its pitch angle. It's conceivable that if the fan body 12 could not be rotated and adjusted, its position when stored would be relatively high. In this case, the liquid storage tank 10 would need to be set higher to accommodate the fan body 12. The higher the liquid storage tank 10 is set, the larger the volume of the spray fan 100 after storage. Therefore, implementing this embodiment can reduce the height of the fan body 12, thereby reducing the volume of the liquid storage tank 10, achieving the technical effect of further reducing the storage volume of the spray fan 100.

[0080] Furthermore, since the fan body 12 in this embodiment can rotate to be positioned at the opening 105 of the liquid storage tank, the retracted spray fan 100 has a high aesthetic appeal and can provide users with a better visual experience.

[0081] Referring to Figure 9, in a specific embodiment, a protective ring 122 is provided on the outer periphery 121 of the fan body.

[0082] Specifically, when the fan body 12 is placed into the liquid storage space 103, the fan body 12 is easily bumped against the liquid storage tank 10, which can easily cause the fan body 12 to be scratched or even damaged. In order to solve this technical problem, this embodiment provides a protective ring 122 on the outer periphery 121 of the fan body. The protective ring 122 can protect the fan body 12 to prevent it from being damaged when it is placed into the liquid storage space 103.

[0083] It is worth mentioning that the protective ring 122 can be a silicone protective ring, a rubber protective ring, or a protective ring made of other materials, as long as it can protect the fan body 12. This embodiment does not limit it.

[0084] Referring to Figures 10-18, in some embodiments, the sidewall 102 is stretchable so that it can deform toward the bottom wall 101 for retraction.

[0085] By implementing this embodiment, the sidewall 102 can be expanded when the spray fan 100 is used, thereby increasing the size of the liquid storage space 103 and enabling the spray fan 100 to have a longer operating range. When it is necessary to store the spray fan 100, the sidewall 102 can be compressed to reduce the volume of the liquid storage tank 10, thereby further reducing the storage volume of the spray fan 100.

[0086] Referring to Figures 15 and 16, in some embodiments, the sidewall 102 has a corrugated ring 1021 so that the sidewall 102 can deform toward the bottom wall 101 for retraction.

[0087] In this embodiment, applying tension to the sidewall 102 can pull the corrugated ring 1021 open, lengthen the sidewall 102, increase the liquid storage space 103, and increase the runtime of the spray fan 100; applying pressure to the sidewall 102 can compress the corrugated ring 1021, shorten the sidewall 102, and reduce the volume of the liquid storage tank 10, thereby achieving the technical effect of further reducing the storage volume of the spray fan 100.

[0088] Referring to Figures 17 and 18, in some embodiments, the sidewall 102 is at least partially made of a flexible material so that the sidewall 102 can deform toward the bottom wall 101 for retraction.

[0089] By implementing this embodiment, applying tension to the sidewall 102 can lengthen the sidewall 102, increase the liquid storage space 103, and increase the runtime of the spray fan 100; applying pressure to the sidewall 102 can shorten the sidewall 102, reduce the volume of the liquid storage tank 10, thereby achieving the technical effect of further reducing the storage volume of the spray fan 100.

[0090] Referring to Figures 17 and 18, in a specific embodiment, the sidewall 102 includes a first ring 1022, a second ring 1023, and a third ring 1024. The first ring 1022 is disposed around the bottom wall 101 and connected to the bottom wall 101. The second ring 1023 is connected between the first ring 1022 and the third ring 1024. The second ring 1023 is made of a flexible material so that the second ring 1023 can deform toward the bottom wall 101 when subjected to force.

[0091] In this embodiment, applying tension to the sidewall 102 can deform the second ring 1023 away from the bottom wall 101, causing the sidewall 102 to be elongated, increasing the liquid storage space 103, and increasing the runtime of the spray fan 100; applying pressure to the sidewall 102 can deform the second ring 1023 towards the bottom wall 101, causing the sidewall 102 to be compressed, reducing the volume of the liquid storage tank 10, thereby achieving the technical effect of further reducing the storage volume of the spray fan 100.

[0092] Referring to Figures 1-14, in some embodiments, the first end 111 is rotatably connected to the bottom wall 101 to adjust the pitch angle of the telescopic rod 11. The first end 111 is spaced apart from the center position 1011 of the bottom wall, and the second end 112 is spaced apart from the center position 123 of the fan body.

[0093] By implementing this embodiment, the height of the fan body 12 can be reduced by adjusting the pitch angle of the telescopic rod 11, thereby achieving the technical effect of reducing the storage volume of the spray fan 100.

[0094] Specifically, since adjusting the pitch angle of the telescopic rod 11 will change the position of the fan body 12 in the horizontal direction (Y direction as shown in Figures 1, 5 and 10), in order to ensure that the fan body 12 can still be rotated and positioned at the opening 105 of the liquid storage tank or covered on the outside 104 of the liquid storage tank after adjusting the pitch angle of the telescopic rod 11, in this embodiment, the first end 111 is spaced apart from the center position 1011 of the bottom wall, and the second end 112 is spaced apart from the center position 123 of the fan body.

[0095] It is worth mentioning that the telescopic rod 11 has a plurality of interlocking first telescopic sections 113. In some embodiments, the height of the fan body 12 can be reduced by increasing the number of first telescopic sections 113. For example, among two telescopic rods 11 with the same total length, the one with more first telescopic sections 113 has a smaller retracted height. Therefore, increasing the number of first telescopic sections 113 can effectively reduce the retracted height of the fan body 12.

[0096] Referring to Figure 19, in a specific embodiment, the spray fan 100 also includes a control circuit module 15. The side 106 of the liquid storage tank away from the first end 111 is provided with a receiving cavity 110 isolated from the liquid storage space 103. The control circuit module 15 is housed in the receiving cavity 110 and is electrically connected to the pump body 14, the fan body 12, and the spray head 13.

[0097] Specifically, because the first end 111 is spaced apart from the center position 1011 of the bottom wall, the stability of the spray fan 100 is lower than in the embodiment where the first end 111 is located at the center position 1011 of the bottom wall. To solve this technical problem, improve the stability of the spray fan 100, and reduce the probability of the spray fan 100 tipping over, this embodiment places the control circuit module 15 on the side 106 of the liquid storage tank away from the first end 111. By placing the control circuit module 15 and the first telescopic rod 11 on opposite sides of the liquid storage tank 10, the beneficial effect of improving the stability of the spray fan 100 is achieved.

[0098] Referring to Figures 20-22, in some embodiments, the spray fan 100 further includes a mounting base 16 and a control circuit module 15. The mounting base 16 is installed on the top 107 of the liquid storage tank. A first end 111 is rotatably connected to the side of the mounting base 16 facing away from the liquid storage space 103 to adjust the pitch angle of the telescopic rod 11. The first end 111 is spaced apart from the center position 161 of the mounting base, and a second end 112 is spaced apart from the center position 123 of the fan body, so that in the second retracted state, the fan body 12 can be rotated and placed on the side of the mounting base 16 facing away from the liquid storage space 103. The control circuit module 15 is disposed within the mounting base 16 and is electrically connected to the pump body 14, the fan body 12, and the spray head 13. Because the mounting base 16 is located above the liquid storage space 103 and will not be immersed in the solution within the liquid storage space 103, implementing this embodiment can reduce the requirements for waterproof performance.

[0099] Referring to Figures 23 and 24, in a specific embodiment, the fan body 12 is provided with a buckle 124, and the mounting base 16 is provided with a slot 162 that cooperates with the buckle 124, so that when the fan body 12 is covered on the side of the mounting base 16 facing away from the liquid storage space 103, the buckle 124 can cooperate with the slot 162 to limit the fan body 12.

[0100] By implementing this embodiment, when the fan body 12 is placed on the side of the mounting base 16 facing away from the liquid storage space 103, the fan body 12 can be limited by the cooperation of the slot 162 and the buckle 124, so as to prevent the fan body 12 from rotating due to external force, resulting in an excellent user experience.

[0101] Referring to Figures 20-22, in some embodiments, the mounting base 16 is provided with a receiving groove 163 on the side facing away from the liquid storage tank 10, and the first end 111 is rotatably connected to the groove wall 1631 of the receiving groove, so that when the fan body 12 is covered on the side of the mounting base 16 facing away from the liquid storage space 103, the receiving groove 163 can accommodate the telescopic rod 11.

[0102] By implementing this embodiment, the telescopic rod 11 can be accommodated in the receiving slot 163 when the spray fan 100 is stored. This not only further reduces the volume of the spray fan 100 when stored, but also improves the aesthetics of the spray fan 100 when stored by hiding the telescopic rod 11.

[0103] Referring to Figure 20, in some embodiments, the mounting base 16 is provided with an inlet 164 communicating with the liquid storage space 103, so that the user can fill the liquid storage space 103 with solution using the inlet 164.

[0104] Referring to Figures 1 and 2, in some embodiments, the spray fan 100 further includes a blocking member 17. The bottom 108 of the liquid storage tank is provided with a drain outlet 109 communicating with the liquid storage space 103. The blocking member 17 is positioned at the drain outlet 109 and is movably connected to the liquid storage tank 10 to cover or expose the drain outlet 109.

[0105] Specifically, the existing spray fan 100 requires tilting the storage tank 10 so that the solution in the storage tank 10 can be discharged through the tank opening 105, which is inconvenient to operate. By implementing this embodiment, when it is necessary to discharge the solution in the storage tank 10, it is only necessary to operate the blocking member 17 to expose the drain outlet 109, so that the solution can be discharged through the drain outlet 109, which is much more convenient to operate.

[0106] It should be noted that there are many specific implementations of the blocking member 17, and this embodiment is not limited to any particular implementation, as long as it can achieve the function of shielding and exposing the drain outlet 109. For example, the blocking member 17 is a pluggable rubber plug; for another example, the blocking member 17 is a cover that is threadedly connected to the drain outlet 109; for yet another example, the blocking member 17 is a cover that is slidably connected to the liquid storage tank 10, and this embodiment is not limited to any particular implementation.

[0107] Referring to Figure 1, in some embodiments, the spray fan 100 further includes a handle 18, which is connected to the liquid storage tank 10. This configuration allows the spray fan 100 to be lifted with one hand using only the handle 18, eliminating the need to carry it with both hands as in existing technologies. Therefore, implementing this embodiment facilitates the handling and transportation of the spray fan 100 by the user.

[0108] Referring to Figure 25, in some embodiments, the spray fan 100 further includes a handle 18, which is connected to the fan body 12. This configuration allows the spray fan 100 to be lifted with one hand using only the handle 18, eliminating the need to use both hands to lift it as in existing technologies. Therefore, implementing this embodiment facilitates the handling and transportation of the spray fan 100 by the user.

[0109] Referring to Figure 8, in some embodiments, the spray fan 100 further includes a control circuit module 15. The bottom of the liquid storage tank 10 is provided with a receiving cavity 110 that is isolated from the liquid storage space 103. The control circuit module 15 is housed in the receiving cavity 110 and is electrically connected to the pump body 14, the fan body 12, and the spray head 13.

[0110] Specifically, compared to the embodiment where the control circuit module 15 is mounted on the fan body 12, this embodiment is advantageous in lowering the center of gravity of the spray fan 100 and improving the stability of the spray fan 100.

[0111] Referring to Figures 1 and 19, in some embodiments, the pump body 14 is disposed in the liquid storage space 103. Compared with the embodiment in which the pump body 14 is disposed on the fan body 12, this embodiment is advantageous in lowering the center of gravity of the spray fan 100 and improving the stability of the spray fan 100.

[0112] Referring to Figures 1 and 26, in some embodiments, the fan body 12 is provided with a buckle 124, and the side wall 102 is provided with a slot 162 that cooperates with the buckle 124. The slot 162 is used to cooperate with the buckle 124 to limit the fan body 12.

[0113] By implementing this embodiment, when the spray fan 100 is in the storage state, the fan body 12 can be limited by the cooperation of the slot 162 and the buckle 124, so as to prevent the fan body 12 from rotating due to external force, resulting in an excellent user experience.

[0114] Referring to Figure 27, in a specific embodiment, at least two slots 162 are provided, and multiple slots 162 are evenly distributed on the side wall 102 near the opening 105 of the liquid storage tank 10. Two buckles 124 are also provided to cooperate with the multiple slots 162 respectively.

[0115] Firstly, since the slot 162 is located on the side wall 102 near the opening 105 of the liquid storage tank 10, the stroke required for the buckle 124 to be inserted into the slot 162 is relatively small, making it easier to insert the buckle 124 into the slot 162.

[0116] Secondly, since at least two slots 162 and buckles 124 that cooperate with slots 162 are provided in this embodiment, the connection stability between the fan body 12 and the side wall 102 can be improved, and the situation where the fan body 12 rotates due to external force can be better avoided.

[0117] It is worth mentioning that there can be two, three, or four slots 162 and buckles 124, and this embodiment does not limit the number of slots 162 and buckles 124. In a specific embodiment, there are two slots 162 and two buckles 124. The two slots 162 are symmetrically arranged on the side wall 102 near the opening 105 of the liquid storage tank 10, and the two buckles 124 are symmetrically arranged on the fan body 12 to cooperate with the two slots 162.

[0118] Referring to Figure 27, in some embodiments, the fan body 12 is provided with a pull ring 125, which makes it convenient for the user to pull open the fan body 12 using the pull ring 125.

[0123] Referring to Figures 19 and 29, in some embodiments, the spray fan 100 further includes a conductor 20, through which the control circuit module 15 is electrically connected to the fan body 12 and the spray head 13. There are many specific ways to set the conductor 20, and three embodiments are listed below for illustration.

[0124] Referring to Figure 19, in Embodiment 1, conductor 20 includes wire 201 and interface 202. Interface 202 is exposed in the liquid storage tank 10 and electrically connected to the control circuit module 15. Wire 201 is located outside the liquid storage tank 10. One end 2011 of the wire is detachably plugged into interface 202, and the other end 2012 is detachably plugged into fan body 12 for electrical connection to fan body 12 and spray head 13 on fan body 12. After using the spray fan 100, simply remove wire 201 and place the entire wire 201 back into the liquid storage tank 10.

[0125] Referring to Figure 29, in Embodiment 2, the conductor 20 is a spring wire 203, which is housed within the telescopic rod 11 so that the conductor 20 can extend and retract with the telescopic rod 11. The advantage of this embodiment is that the conductor 20 can be concealed within the telescopic rod 11, thus providing a better visual experience for the user when using the spray fan 100.

[0126] Referring to Figure 29, in Embodiment 3, the conductor 20 is housed within the telescopic rod 11.
