[0026] The present invention will be described in further detail below in conjunction with the accompanying drawings.

[0027] according to Figures 1 to 6 , a fan structure of an external spray assembly, comprising a fan body 1, an atomizing nozzle 2, and a spray assembly 3. The front end of the fan body 1 is provided with a fan cover 4, and the front end of the fan cover is detachably fixed with the spray assembly 3. The improvement is that the detachable fixing includes a through hole 5 at the front end of the fan cover 4, a fixing seat 6 is fixed in the through hole 5, and a convex ring portion 8 of a fixing cavity 7 is formed at the bottom of the fixing seat 6. A plurality of groups of elastic latch assemblies 9 are distributed circumferentially in the fixing cavity 7. Correspondingly, the convex ring portion 8 is distributed with pin holes 10. The elastic latch assembly 9 includes a latch 11 and a spring 12 at the bottom of the latch 11, which always applies an outward pushing force so that the head of the latch 11 is pushed out of the pin hole 10. The spray assembly 3 has a fixing ring 13 extending backward, and an annular groove 31 is provided on the inner wall of the fixing ring 13, so that the head of the latch 11 is against the annular groove 18 on the inner wall of the fixing ring 13 to achieve locking. The annular groove 18 can help users to lock it no matter which angle it is inserted.

[0028] The multiple groups of elastic latch assemblies 9 are three to four groups evenly distributed around the circumference. The bottom of the fixed cavity 7 is evenly distributed with three to four groups of slide groove cavities 14 along the circumference. A latch 10 is fixed in the slide groove cavity 14. The bottom of the latch 10 is sleeved with a spring 12. The main body of the latch 11 is rectangular and matches the slide groove cavity 14. A slide bar is provided on the outer wall of the latch 11 to reduce the friction of the latch 11 in the slide groove cavity 14 to increase the service life. The top of the latch 10 is provided with a conical plug 15 to match the pin hole 10, so that the user can easily fix and pull it out. The top of the fixed seat 6 is fixed with a front mesh cover 19, which matches the fixed seat 6 to fix the elastic latch assembly 9 in the slide groove cavity 14.

[0029] The spray assembly 3 includes a spray base 16, a spray hood 17 is fixed on the top of the spray base 16, and an atomizing nozzle 2 is fixed on the top of the spray hood 17. A first pipe joint 20 and a second pipe joint 21 are fixed between the spray hood 17 and the spray base 16, and the first pipe joint 20 and the second pipe joint 21 are connected by a silicone hose 22 and fixed with a metal clamp 23 to prevent loosening and water leakage. The other end of the first pipe joint 20 is fixedly connected to the atomizing nozzle 2. A water inlet 24 is provided at the bottom of the second pipe joint 21, and correspondingly, the water inlet 24 is connected to the water inlet assembly 25 to achieve the connection of the waterway.

[0030] The water inlet assembly 25 includes a PE water pipe 26, one end of which is fixed with a water inlet joint 27, which matches the water inlet 24 to realize the water outlet function, and the other end of the PE water pipe 26 is fixed with a six-tap joint 28 and a water pipe ball valve 29, and a stainless steel mesh 30 is fixed inside the six-tap joint 28. The water pipe ball valve 29 and the six-tap joint 28 are connected and fixed to the faucet, so that water is connected to the spray assembly 3 through the PE water pipe 26, and the stainless steel mesh 30 prevents dirt from entering the PE water pipe 26 and causing blockage.

[0031] When the user needs to install or remove the spray assembly 3 to the fan body 1, he only needs to pass the fixing ring 13 of the spray base 16 through the through hole 5 on the fan cover 4 and align it with the fixing seat 6, press the spray base 16 into the fixing seat 6, and when the pin 11 of the elastic pin assembly 9 passes through the pin hole 10, it is inserted into the annular groove 31 on the inner wall of the fixing ring 13 to complete the fixation. Finally, the user can also use force to pull the spray assembly 3 off the fixing seat 6, and the pin plug 15 of the pin 11 is arc-shaped, so the user does not need to use too much force.

[0032] When the user needs to use the spray function on the fan, he only needs to insert the water inlet connector 27 of the water inlet assembly 25 into the water inlet 24, and connect the water pipe ball valve 29 and the six-tap connector 28 at the other end of the PE water pipe 26 to the faucet. Then the water will flow through the water inlet assembly 25, and through the second pipe connector, the silicone hose, and the first pipe connector of the spray assembly 3, and finally spray out from the atomizing nozzle 2.

[0033] Beneficial effects: When it is hot and the environment where the fan is used is dry, the spray component can be installed to improve the ambient humidity. At the same time, the wind blown out is cooler, giving users a better experience.
