Description

Technical Field

[0001] This utility model relates to the field of spray fan technology, specifically a spray cooling fan. Background Technology

[0002] A misting fan is a product with a misting device on its main body. The misting device atomizes water, and the airflow generated by the fan carries the water mist outward, thereby achieving a better cooling effect and increasing the humidity of the ambient air.

[0003] Conventional misting fans use ultrasonic atomizing plates to atomize liquid water into a mist that is then sprayed outwards. This requires an integrated water tank on the fan body to provide water for the ultrasonic atomizing plates without compromising portability. However, in the portable fan field, the water tank capacity is greatly limited. If the water tank capacity is too large, the product appearance will be very unsightly and out of place. On the other hand, if the water tank is too small, it cannot meet the atomization requirements and requires frequent refilling. This creates a contradiction between practicality and portability, which has become a problem that urgently needs to be solved by those skilled in the art. Utility Model Content

[0019] Please see Figure 1-8 A spray cooling fan includes an air-driving part 1, which includes an air passage 18. A water storage tank 13 is disposed on the outer side of the air passage 18 and is arranged circumferentially around the air passage 18. A first connecting part 19 is provided extending downward below the air-driving part 1. An atomizing through hole 133 is provided on the first connecting part 19. The atomizing through hole 133 is disposed below the water storage tank 13 and is connected to the interior of the water storage tank 13. An atomizing plate 12 is encapsulated on the atomizing through hole 133. The air duct 18 and the first connecting part 19 are integrally formed, forming an "L-shaped" component. The water tank 13 is an annular component, and a mounting through hole is formed at the axis of the water tank 13. The water tank 13 is sleeved and installed on the circumference of the air duct 18 through the mounting through hole. The air-driving part 1 includes a front shell 11 and a rear shell 17. The air duct 18 is formed on the rear shell 17, and the front shell 11 is located at the air outlet of the air duct 18. On one side, the front shell 11 and the rear shell 17 of the air-driving part are snapped together, and the water storage tank 13 is sandwiched between the front shell 11 and the rear shell 17 of the air-driving part. The water storage tank 13 includes a first water tank shell 131 and a second water tank shell 132 that are connected to each other. A water storage cavity 134 is formed between the first water tank shell 131 and the second water tank shell 132.

[0020] The air passage 18 has an air inlet and an air outlet at both ends. An internal support 15 is provided inside the air passage 18, and a drive fan blade assembly 16 is installed on the internal support 15. The drive fan blade assembly 16 guides the air located at the air inlet into the air passage 18 and then accelerates and blows it out from the air outlet. The fan blade assembly 16 is disposed on the side of the internal support 15 facing the air inlet. A cooling device 14 is disposed on the side of the internal support 15 facing the air outlet. The cooling device 14 includes a conductive element 141, a thermoelectric cooler 142, and a heat sink 143. The heat sink 143 is disposed close to the internal support 15. The thermoelectric cooler 142 is sandwiched between the conductive element 141 and the heat sink 143. The thermoelectric cooler 142 includes a heat dissipation end and a cooling end. The heat dissipation end is thermally connected to the heat sink 143, and the cooling end is thermally connected to the conductive element 141. The end of the conductive element 141 facing away from the thermoelectric cooler 142 extends outward from the air outlet. The conductive element 141 and the heat sink 143 are preferably made of aluminum alloy to improve heat conduction efficiency. At the same time, aluminum alloy components are easier to process when producing castings.

[0021] The lower end of the air-driving part 1 is rotatably connected to a gripping part 2, and the upper end of the gripping part 2 is provided with a second connecting part 21. The first connecting part 19 has first bolt through holes 191 symmetrically arranged on its left and right sides.

The first connecting part 19 is rotatably connected to the second connecting part 21 by setting a bolt 3 to connect the first bolt through holes 191 and the second bolt through holes 211, thereby realizing the rotatable connection between the air-driving part 1 and the gripping part 2. A damping ring 4 is sandwiched between the first connecting part 19 and the second connecting part 21. The damping ring 4 is sleeved on the circumference of the bolt 3.

The USB interface 263 is located in the pre-set through hole of the grip part 2 housing and extends outward from the through hole. The display screen 261 is used to display the real-time working status and working mode of the drive fan blade assembly 16, the atomizing plate 12 and the cooling device 14, and can also be used to display the power storage value of the battery 27. The control button 262 is used to control and adjust the working status and working mode of the drive fan blade assembly 16, the atomizing plate 12 and the cooling device 14. When the USB interface 263 is connected to an external power supply with a charging cable, it can replenish the power of the battery 27.

[0023] The lower end of the grip portion 2 is provided with a buckle 5, which allows the fan body to be hung on a belt or backpack for easy carrying. It can also be hooked onto a nail or hook on the wall for use as a wall-mounted fan. The outer side of the second connecting portion is provided with a hanging rope ear 212. When the two ends of the hanging rope are connected to the hanging rope ear 212 respectively, as... Figure 8 As shown, this allows the fan body to be used as a neck fan, and after deformation, it becomes like... Figure 7 As shown, the fan itself can be used as a desktop fan.

[0024] In summary, this utility model cleverly arranges the water tank 13 around the air duct 18, which not only enables a large-capacity water tank to meet the water demand of the atomizing device, but also effectively avoids the adverse effects of a large-capacity water tank on the product's appearance and portability. In addition, the cooling device 14 can add a cooling care function to the fan, and the rotating structure between the air drive part 1 and the handle part 2 can realize the fan's form transformation, making it not limited to handheld use. It can also be used with buckles and lanyard ears to achieve multiple usage methods such as desktop, wall-mounted, and neck-wearing, greatly improving the fan's practicality.
