[0021] ​Figure 5 for Figure 4 The exploded diagram. Detailed Implementation

[0022] The present invention will be further described in detail below with reference to the accompanying drawings and embodiments.

[0023] like Figures 1 to 5 As shown, a dual-headed spray fan that can oscillate left and right and can be used as a tabletop or stand fan includes a main unit A and a main unit base 20. The main unit A is mounted on the main unit base 20. The main unit A includes two spray fan assemblies 10 arranged symmetrically at the front and back. The main unit base 20 is cylindrical. The main unit base 20 is equipped with an oscillation motor 7 that drives the main unit A to oscillate left and right. Several openable and closable support feet 30 are hinged to the lower end of the main unit base 20. When the support feet 30 are open, they form a support foot structure 60 for a tabletop fan. When the support feet 30 are closed, they form an insertion structure 70 for insertion and positioning with the upper end of the column 9 of a stand fan. The lower end of the column 9 is fixed on the column base 100.

[0024] The specific structure is as follows: The spray fan assembly 10 includes a front cover 1, a rear cover 2, an outer cover 3, fan blades 4, and a water tank 5. The front cover 1 and the rear cover 2 are connected together. The outer cover 3 is fitted over the front cover 1. The water tank 5 is located outside the front cover 1 and fixed by the outer cover 3. The water outlet 52 at the front end of the water tank 5 is connected to an atomizer 8 located at the center of the front cover. The atomizer 8 typically has a housing with an atomizing head 81 at the center of the housing. The atomizing head 81 can be an ultrasonic atomizing head. The front of the housing has an opening 82 and a cover 83 that can be rotated open or closed. The rear covers 2 of the two sets of fan atomizing assemblies 10 are connected and communicate with each other to form a single unit. A drive shaft 6 is horizontally inserted through the middle of the two rear covers 2. The two ends of the drive shaft 6 are respectively connected to the two sets of fan blades 4. A drive motor 50 is connected to the middle of the drive shaft 6.

[0025] The main unit base 20 is a cylindrical structure with a narrowed diameter at the top and bottom. A rotating component 21 is protruding from the upper end of the main unit base 20. The longitudinal section of the rotating component 21 is an inverted U-shape. After the two rear covers 2 are connected, a cavity is formed at the bottom for the rotating component 21 to be inserted. A disc damping shaft 22 is inserted through the inner hole of the rotating component 21. The left and right ends of the disc damping shaft 22 are fixed to the inner wall of the cavity. The main unit A can be rotated left and right on the main unit base 20 by the oscillating motor 7, and can be manually oscillated up and down at a certain angle relative to the main unit base 20 by the disc damping shaft 22.

[0026] The support leg 30 of the embodiment is four, which are circumferentially and uniformly spaced on the lower end of the main machine base 20. One of the support legs 30 is provided with a button a on the outside, and the upper end of the support leg 30 is a circular shaft 301 which is convenient to rotate. The circular shaft 301 is provided with a cylindrical hole 201 at the step surface of the reduced diameter section, which is used to position and limit the rotation of the upper end of the support leg. When the support leg 30 is unfolded, the bottom of the support leg 30 is basically flush with the bottom of the main machine base 20, forming a support leg structure 60 of the table fan. When the support leg 30 is closed, it is in the shape of a cylinder, thereby forming an insertion structure 70 which is inserted and positioned on the upper end of the stand 9 of the vertical fan. The upper end of the stand 9 is provided with a positioning socket for the insertion of the insertion structure 70. The upper end of the stand 9 is provided with a corresponding button hole which is positioned and matched with the button a on the outside of the support leg 30, thereby realizing the positioning and unlocking of the insertion structure 70 and the stand 9.

[0027] The water tank 5 is a fan-shaped frame structure with a circular arc upper end surface. The water tank 5 is sleeved on the outer upper part of the front cover 1, and the circular arc inner wall of the water tank 5 is matched with the outer wall of the front cover 1. The water inlet 51 of the water tank 5 is located at the upper end of the circular arc surface, and the water outlet 52 is located at the center of the fan-shaped structure. The water outlet 52 is connected with the water tank 5 through the water pipe 50. The front end of the front cover 1 is provided with a positioning seat for positioning the water outlet 52. The positioning seat is provided with a positioning rib 12 between the outer wall and the inner wall of the front cover 1 for embedding the water pipe 50. The upper end surface of the outer cover 3 is provided with a hollow part corresponding to the position of the water inlet 51 of the water tank 5. A water inlet cover 53 which can be opened and closed is hinged to the hollow part of the outer cover 3.

[0028] The rear end of the front cover 1 is buckled and positioned with the rear cover 2, and then fixed by screws. The outer cover 3 is sleeved on the outer side of the front cover 1 and fixed by screws. A decorative ring 30 is buckled to the front end of the outer cover 3.

[0029] The two rear covers 2 of the embodiment are an integral part, and the upper end of the two rear covers 2 is provided with a handle 40.

[0030] The fan operation and spraying principle of the embodiment is consistent with the prior art, which will not be described here.

[0031] When in use, the main machine A can be shaken left and right through the shaking motor 7. Since there are two front and rear spraying fan assemblies 10, air can be blown out from both the front and rear surfaces during operation, and spraying can be performed on both the front and rear surfaces, thereby greatly increasing the cooling area. The main machine A can also be manually swung up and down to adjust the angle and improve the cooling effect. The main machine A can be directly used as a table fan (such as Figure 1 ), or inserted into the stand 9 to form a vertical fan (such as Figure 3 ), thereby meeting the needs of different scenes.

[0032] The above merely is the preferred implementation manner of the present application, and it should be noted that, for the ordinary skilled in the art, without departing from the technical principles of the present application, a number of improvements and refinements can be made, and these improvements and refinements should also be considered as the protection scope of the present application.
