In addition, the terms "first", "second", and "third" are used for descriptive purposes only, and cannot be understood as indicating or implying relative importance.

[0039] like Figures 1 to 6 As shown, the bladeless fan nozzle assembly in this embodiment includes: a duct assembly, which cooperates with the base assembly 7 and has an air duct for the wind generated by the base assembly 7 to pass through; and a wind sweeping assembly 1, which includes a plurality of air guide blades 14 rotatably arranged in the air duct of the air duct assembly, and a driving frame 13 that cooperates with the air guide blades 14 and is used to drive the plurality of air guide blades 14 to rotate; wherein the driving frame 13 can swing back and forth under the drive of the power device to adjust the rotation angle of the air guide blades 14 in the air duct, and then the bladeless fan in this embodiment is adopted. While the bladeless fan realizes air supply, by arranging rotatable air guide blades 14 in the air duct of the air duct assembly, the air guide blades 14 can guide the wind direction in the air duct, thereby realizing the change of wind direction, realizing the adjustment of the air outlet angle, and improving the user experience.

[0040] Specifically, the wind guide blades 14 can rotate in the up and down directions, thereby realizing the up and down sweeping of the bladeless fan. Since it has a variety of air outlet modes, the wind direction can be adjusted according to the needs of the user to meet the use of various occasions.

[0041] Specifically, the power device in this embodiment is an adjusting motor 22 installed on the air duct assembly. The bladeless fan also includes a crank 12 arranged on the driving frame 13. The motor shaft of the adjusting motor 22 is connected to the crank 12. Driven by the adjusting motor 22, the crank 12 rotates, thereby driving the driving frame 13 to move up and down, driving the air guide blades 14 coordinated with the driving frame 13 to rotate, thereby realizing the adjustment of the blowing angle of the bladeless fan. The whole structure is simple and reliable.

[0042] The bladeless fan nozzle assembly in this embodiment also includes a rotating buckle structure disposed between the wind guide blade 14 and the air duct assembly, and the wind guide blade 14 is rotatably matched with the air duct assembly through the rotating buckle structure. Specifically, the wind guide blade 14 in this embodiment is provided with a first buckle 11, and the air duct assembly is provided with a first slot 21. The wind guide blade 14 is rotatable in the air duct through the first buckle 11 and the first slot 21 that cooperate with each other, and the angle is adjusted under the drive of the driving frame 13. Specifically, the wind guide blade 14 in this embodiment is hingedly matched with the driving frame 13.

[0043] Specifically, the air duct assembly in this embodiment includes a front air duct 3 and a rear air duct 2, and the air duct is surrounded by the front air duct 3 and the rear air duct 2. The front air duct 3 and the rear air duct 2 are welded and assembled, and are fastened by a first screw hole 31 provided on the front air duct 3 and a first screw column 23 provided on the rear air duct 2, thereby facilitating the installation and design of the air duct assembly.

[0044] The bladeless fan nozzle assembly in this embodiment also includes a decorative assembly arranged outside the air duct assembly, the decorative assembly includes an inner decorative part 4 and an outer decorative part 5 that are buckled with each other, the second buckle 32 in the front air duct 3 is buckled with the second slot 41 in the inner decorative part 4, and the third buckle 51 of the outer decorative part 5 is buckled with the third slot 34 of the front air duct 3. The second screw hole 33 of the front air duct 3 cooperates with the second screw column 42 in the inner decorative part 4. Thus, the bladeless fan in this embodiment is more aesthetically pleasing, and the reliability of the installed bladeless fan is better.

[0045] The present embodiment also provides a bladeless fan, including a bladeless fan nozzle assembly and a base assembly 7 for supplying air to the bladeless fan nozzle assembly. The bladeless fan nozzle assembly is the bladeless fan nozzle assembly as described above, and the advantages of the above-mentioned bladeless fan nozzle assembly should also be possessed by the bladeless fan nozzle assembly in the present embodiment, which will not be repeated here.

[0046] Furthermore, the bladeless fan in this embodiment also includes a bottom cover assembly 6 arranged between the base assembly 7 and the air duct assembly. The bladeless fan also includes a PM2.5 sensor 62 arranged on the bottom cover assembly 6, so that the bladeless fan can also detect PM2.5. A negative ion emitter 63 and a display panel 64 are also arranged on the bottom cover assembly 6. The bottom cover assembly 6 is assembled to the outer decorative part 5 through the fourth buckle 61 to achieve complete installation and fixation of the head assembly, and finally the third screw hole 71 in the base assembly 77 is assembled to the third screw column 65 in the bottom cover assembly 6 to achieve complete fixation of the whole machine.

[0047] When in use, the user can operate the remote control to select the air outlet mode according to his or her preferences. When the normal up and down sweeping mode is selected, the sweeping component 1 will be adjusted to a certain angle according to the setting program. For example, the wind outlet angle can satisfy the human body at a distance of 2m, and the human body can feel the soft air volume from the head to the body, thereby improving comfort. When the user turns on the purification mode, the sweeping component 1 will hit the top 60° angle, the wind will blow upwards, and will not blow directly on the human body, and the air volume will increase by about 10m3 / h compared to the normal direct blowing, thereby increasing the air purification value, accelerating air circulation, and obtaining a more efficient purification energy efficiency of about 5m3 / W·h. When the user selects the sleep mode, the sweeping component 1 will move slowly, and the air volume will be reduced after the set time after the human body falls asleep, thereby improving the comfort of the human body during sleep, and will not cause colds and fevers because the human body still feels a large amount of air after deep sleep.

[0048] Obviously, the above embodiments are merely examples for the purpose of clear explanation, and are not intended to limit the implementation methods. For those skilled in the art, other different forms of changes or modifications can be made based on the above description. It is not necessary and impossible to list all the implementation methods here. The obvious changes or modifications derived therefrom are still within the scope of protection of the invention.
