Obviously, the described embodiments only constitute some embodiments of the present application, rather than all the embodiments. Based on the embodiments in the present application, all the other embodiments obtained by those skilled in the art without creative labor fall within the protection scope of the present application.

[0025] Please refer to the drawings of the present application Figure 1 to the drawings of the present application Figure 4The embodiment provides a bladeless fan lamp, which comprises a shell 1, a wind wheel structure 2, a wind channel assembly arranged in the shell 1, an air inlet 101 and an air outlet 102 arranged on the shell 1, a wind inlet end of the wind channel assembly in communication with the air inlet 101, a wind outlet end of the wind channel assembly in communication with the air outlet 102, the wind wheel structure 2 arranged at the wind inlet end of the wind channel assembly, and an air outlet flow channel 30 formed between the wind wheel structure 2, the wind channel assembly and the air outlet 102. Air enters the wind inlet end of the wind channel assembly in the shell 1 from the air inlet 101, is sent out from the air outlet 102 after passing through the air outlet flow channel 30 under the driving of the wind wheel structure 2. The bladeless fan lamp provided by the embodiment has the wind wheel structure 2 arranged at the wind inlet end of the wind channel assembly in the shell 1, the air outlet flow channel 30 formed between the wind wheel structure 2, the wind channel assembly and the air outlet 102 to realize air sending, the wind wheel structure 2 is hidden in the shell 1 and does not protrude from the lower end surface of the shell 1, so that the bladeless fan lamp is more beautiful, and the wind wheel structure 2 hidden in the shell 1 has less dust accumulation compared with the wind wheel structure 2 exposed outside, so that the bladeless fan lamp does not need to be cleaned frequently, and user experience is improved.

[0026] Further, the air outlet 102 is arranged below the wind wheel structure 2, the wind channel assembly comprises a front air guide plate 31 and a rear air guide plate 32, the front air guide plate 31 extends from the front side of the air outlet 102 to the front lower side of the wind wheel structure 2, the rear air guide plate 32 extends from the rear side of the air outlet 102 to the rear upper side of the wind wheel structure 2, so as to form the air outlet flow channel 30 between the wind wheel structure 2, the front air guide plate 31, the rear air guide plate 32 and the air outlet 102. Air enters the wind inlet end of the wind channel assembly in the shell 1 from the air inlet 101, is sent out from the air outlet 102 below the wind wheel structure 2 after passing through the air outlet flow channel 30 under the driving of the wind wheel structure 2.

[0027] Further, in order to improve the wind pressure and wind speed and reduce the system noise, the air outlet flow channel 30 comprises a first air duct 301 and a second air duct 302 connected in series, the first air duct 301 is arranged between the rear air deflector 32 and the wind wheel structure 2, the air duct width of the first air duct 301 gradually increases from small to large, the second air duct 302 is arranged between the rear air deflector 32 and the front air deflector 31, and the air duct width of the second air duct 302 gradually decreases from large to small. Under the driving of the wind wheel structure 2, the air is sequentially sent out from the air inlet end of the air duct assembly through the first air duct 301 and the second air duct 302. Since the second air duct 302 is located below the wind wheel structure 2, and the air duct width of the second air duct 302 gradually decreases from large to small, according to the principle of fluid mechanics, when the air passes through a narrower channel, the flow rate will increase, and the pressure will also increase accordingly. At the same time, the second air duct 302 gradually narrows from large to small, which helps to reduce the occurrence of vortex, thereby reducing noise generation, and the air can be more concentratedly sent out.

[0028] Further, the air outlet flow channel 30 further comprises a third air duct 303, the third air duct 303 is arranged below the second air duct 302 and connected with the air outlet 102, and the air duct width of the third air duct 303 gradually increases from small to large. The third air duct 303 has an expanding trend, which is conducive to increasing the air supply amount at the air outlet 102, and can maintain the directionality of the airflow after the airflow leaves the air outlet, so that the airflow can be blown farther.

[0029] Further, the air duct stroke of the third air duct 303 is smaller than the air duct stroke of the second air duct 302. The structure design is reasonable, the air passes through the second air duct 302 with a longer stroke to improve the wind speed and wind pressure and reduce the noise, and then passes through the third air duct 303 with a shorter stroke to realize diffusion air supply.

[0030] Further, the air outlet flow channel 30 further comprises a fourth air duct 304, the fourth air duct 304 is arranged between the second air duct 302 and the third air duct 303, and the air duct width of the fourth air duct 304 is fixed. By arranging the fourth air duct 304, the air has a gentle transition interval after passing through the second air duct 302 and before entering the third air duct 303, so that better air supply effect is realized.

[0031] Further, in some embodiments, the front air guide plate 31 comprises a first front air guide section 311 connected with the air outlet 102 and a second front air guide section 312 connected with the first front air guide section 311, and an included angle a is arranged between the first front air guide section 311 and the second front air guide section 312, and the included angle a is greater than 90 degrees. The first front air guide section 311 of the embodiment extends in the vertical direction, and the second front air guide section 312 extends upwardly from back to front in an inclined manner, so that the included angle a between the first front air guide section 311 and the second front air guide section 312 is greater than 90 degrees, and the inclined second front air guide section 312 has a gap with the impeller structure 2, and the gap is reasonably designed to facilitate reducing vortex and noise. An arc-shaped transition section is arranged between the first front air guide section 311 and the second front air guide section 312 to realize smooth transition between the first front air guide section 311 and the second front air guide section 312.

[0032] Further, in some embodiments, the rear air guide plate 32 comprises a first rear air guide section 321 connected with the air outlet 102 and a second rear air guide section 322 connected with the first rear air guide section 321, and the second rear air guide section 322 is detachably connected with the first rear air guide section 321. The air duct assembly of the embodiment further comprises an impeller mounting plate 34 arranged between the front air guide plate 31 and the rear air guide plate 32, and the impeller structure 2 is mounted at the air inlet end of the air duct assembly by being connected with the impeller mounting plate 34. Since the second rear air guide section 322 of the rear air guide plate 32 is detachably connected with the first rear air guide section 321, during installation, the impeller structure 2 can be connected with the impeller mounting plate 34 to realize installation, and then the second rear air guide section 322 of the rear air guide plate 32 is connected with the first rear air guide section 321, so that the impeller structure 2 is conveniently installed.

[0033] Further, in some embodiments, the air duct assembly comprises a flow separation baffle 33 arranged at the air outlet 102 to separate the air outlet 102 into a front air outlet 1021 and a rear air outlet 1022. After the air passes through the air outlet flow duct 30, part of the air is sent out from the front air outlet 1021, and part of the air is sent out from the rear air outlet 1022, which is beneficial to air flow separation and diffusion.
