Compared with the prior art that unidirectional circulating air is formed in the annular air duct through the two air outlets, the technical scheme of the embodiment selects to output two paths of air with different wind directions through one air supply pipe.

The inventor finds that the selection of two paths of air supply pipes in the prior art seems to increase the air output, and the length of an Archimedes spiral air duct is greatly shortened, so that the supercharging effect of air is greatly influenced. Meanwhile, unidirectional circulating air supply is selected in the prior art, so that air continuously and invalidily circulates in the annular air duct, and finally, the air quantity discharged through the air outlet is not great. According to the technical scheme, the air supply is performed through the air supply pipe, so that the length of the Archimedes spiral air duct is prolonged, and the supercharging effect of the air is improved. Meanwhile, the technical scheme of the embodiment selects to output two paths of wind with different wind directions at the same time, which looks like the collision of wind directions, and the wind pressure is increased and the air output is further increased through the opposite impact of the wind. Meanwhile, the fan of the embodiment has a simple structure, does not need to additionally increase a pressurizing mechanism, does not need to greatly change the appearance of a product, and can remarkably improve the air supply effect.

The blade-free fan has unique modeling and air supply technology, and the hidden blade design of the blade-free fan cannot cover dust or hurt fingers inserted by children, so that the blade-free fan is more and more popular in the market. In the related art, the wind only has one flow direction in the wind outlet duct, and when the wind flows out through the wind outlet, the speed of the wind is gradually reduced when flowing, and then the wind cannot be effectively blown to a user, so as to solve the problems. As shown in fig. 1 and fig. 3 to 5, in the present embodiment, the fan includes a base 10, a fan 20, an air duct structure 30, and an air outlet 40. The base body 10 has a cavity 11. A blower 20 is mounted within the cavity 11. The air duct structure 30 includes a first air duct structure 31 and a second air duct structure 32 in communication with the first air duct structure 31, and the first air duct structure 31 is disposed between the cavity 11 of the base 10 and the second air duct structure 32. The air outlet 40 is disposed on the second air duct structure 32. The second air duct structure 32 includes a first air duct section 321 and a second air duct section 322 that are mutually communicated, the first air duct section 321 and the second air duct section 322 are both communicated with the first air duct structure 31, and the air flow direction in the first air duct section 321 is opposite to the air flow direction in the second air duct section 322.

By applying the technical scheme of the embodiment, the fan 20 is arranged in the cavity 11, the air duct structure 30 comprises a first air duct structure 31 and a second air duct structure 32, and the first air duct structure 31 is communicated with the second air duct structure 32 and the cavity 11 and is positioned between the second air duct structure 32 and the cavity 11. The air outlet 40 is disposed on the second air duct structure 32. The second air duct structure 32 includes a first air duct section 321 and a second air duct section 322, and a communication position of the first air duct section 321 and the second air duct section 322 corresponds to the first air duct structure 31. The flow direction of the gas in the first duct section 321 and the second duct section 322 is opposite. As can be seen from the above description, the air blown by the fan 20 flows to the connection part between the first air duct section 321 and the second air duct section 322 through the first air duct structure 31, and is split at the connection part between the first air duct section 321 and the second air duct section 322, that is, the air enters the first air duct section 321 and the second air duct section 322 respectively, flows in the first air duct section 321 and the second air duct section 322, and flows out through the air outlet 40, so that the air volume can be effectively enhanced, and uneven air outlet can be avoided. Therefore, the technical scheme of the embodiment effectively solves the problem of poor user experience caused by smaller air quantity in the related technology.

It should be noted that, the second air duct structure 32 of the present embodiment is an annular structure, and the wind in the first air duct section 321 and the wind in the second air duct section 322 can collide, i.e. strong convection wind is generated, so that the wind volume and the wind speed can be improved.

In this embodiment, the air outlet of the fan 20 is one, and the air outlet of the fan 20 is communicated with the first air duct structure 31, so that the air speed of the fan can be ensured to be fast enough, and the air quantity of the lamp is further high enough. If the air outlets of the fans 20 are provided, the air speed is reduced, the air quantity is reduced, and the user experience is poor.

In order to avoid the loss of the wind velocity, as shown in fig. 1 and 3, in the present embodiment, the extending direction of the axis of the first air duct structure 31 is parallel to the radial direction of the blower 20, and the second air duct structure 32 is a ring-shaped structure. The above arrangement can make the wind blown out by the fan 20 flow into the first air duct section 321 and the second air duct section 322 respectively on one hand, and on the other hand can just correspond to the air outlet of the fan 20, so that the consumption of the wind blown out by the fan 20 can be effectively reduced, and the air quantity is ensured. In addition, the arrangement structure is simple and convenient to process. Specifically, the fan 20 of the present embodiment is a centrifugal fan.

In an embodiment not shown in the figures, the first air duct structure extends in the radial direction of the fan, which also enables the air blown by the fan to flow into the first air duct structure. If the fan adopts axial fan, then first wind channel structure extends along the axial of fan, in order to guarantee the maximize of amount of wind this moment, need make the extending direction of first wind channel structure and the axis collineation of fan.

As shown in fig. 1 and 3, in the present embodiment, the first air duct structure 31 is a straight air duct, and the arrangement of the straight air duct is convenient for the flow of wind, so that the first air duct structure 31 can avoid the interference to the flow of wind.

In an embodiment not shown in the figures, the first duct structure is a curved duct. The curved air duct can also effectively circulate the wind.

Because the angle between the first air duct section 321 and the first air duct structure 31 is an acute angle, the air quantity flowing into the first air duct section 321 is smaller, and the air quantity of each air outlet 40 is different, and in order to avoid the occurrence of the above situation, the inventor has provided a flared air guiding structure 60 at the connection position of the first air duct structure 31 and the second air duct structure 32 through a great deal of experiments. As shown in fig. 3, in this embodiment, the arrangement of the flared air guiding structure 60 can effectively reduce the vortex generated at the junction of the first air duct structure 31 and the first air duct section 321, so that the flow velocity of the air can be further ensured, the air volume of the air flowing out through the air outlet 40 can be further improved, and the user experience can be better.

As shown in fig. 3, in this embodiment, the generatrix of the flared wind guiding structure 60 is an arc, the radius of the arc is 8mm, and the radius of the arc needs to be matched with the overall size of the lamp to avoid vortex. Of course, the radius of the arc may be between 5mm and 10 mm.

In order to avoid the blown air from being sucked into the air inlet, as shown in fig. 1 and 5, in the present embodiment, the air inlet 12 is disposed on the base 10, the air inlet 12 is located above the fan 20, and an atmospheric air area is formed between the air inlet 12 and the fan 20. The air inlet 12 is arranged above the fan, and a screen structure is arranged at the air inlet 12, so that impurities can be prevented from entering the first air channel structure 31 and the second air channel structure 32. Meanwhile, since the air inlet 12 is disposed above the blower, that is, above the air outlet 40, the blown air is prevented from being sucked into the air inlet 12, and thus the blowing effect can be indirectly ensured.

The above-described normal pressure air region is only with respect to the pressurized air in the duct structure 30. In practical applications, the air pressure in the atmospheric air region may be slightly lower than the ambient air pressure due to the resistance of the air inlet 12.

In order to avoid backflow of wind, that is, to avoid the wind flowing from the blower to the air inlet, as shown in fig. 1, in this embodiment, a backflow preventing baffle 13 is further disposed on the substrate 10, where the backflow preventing baffle 13 is located between the normal pressure air region and the blower 20, and the backflow preventing baffle 13 shields the periphery of the air inlet of the blower 20. The backflow prevention baffle 13 separates a normal air pressure area and a compressed air area (in the air channel structure 30), so that air cannot backflow, and the fan 20 is matched with an Archimedes spiral air channel to form a strong convection air channel with high wind speed and high wind pressure.

In order to improve the backflow preventing effect, as shown in fig. 1, in this embodiment, the backflow preventing baffle 13 includes a first shielding section and a second shielding section, the first shielding section is connected to the first shielding section above the fan 20, and at least part of the structure of the second shielding section extends into the air inlet of the fan 20. The first shielding section and the second shielding section are matched, so that the shielding effect is better, and even if wind flows between the fan 20 and the backflow prevention baffle 13, the wind can flow back into the air inlet of the fan 20 through the action of the second shielding section.

As shown in fig. 4 and 5, in the present embodiment, the fan 20 includes an impeller, a plurality of blades are disposed on the impeller at intervals, the diameter of the impeller is a1, and the distance between two adjacent blades near the periphery of the impeller is a2, where a1 and a2 satisfy a2= (0.1-0.5) ×a1. The ratio relation can obtain higher air pressure and wind speed. Specifically, in the present embodiment, a2=0.3a1.

In order to avoid the wind screen from being damaged, as shown in fig. 1 and 2, in this embodiment, the fan further includes a wind screen 70, where the wind screen 70 is obliquely disposed, and the wind screen 70 is connected below the second air duct structure 32, and an air outlet 40 is formed between the wind screen 70 and the second air duct structure 32. Since the wind deflector 70 is inclined such that the size of the air outlet 40 is smaller than the cross-sectional size of the second duct structure 32, wind can flow out through the air outlet 40, the flow rate of wind can be increased, and further wind can be blown for a longer distance. Specifically, the wind deflector 70 is an arc-shaped plate, which also enables the wind deflector 70 to guide wind, avoiding direct blowing of the wind.

As shown in fig. 1 and 2, in the present embodiment, the wind deflector 70 gradually rises from the axis closer to the fan 20 to the axis farther from the fan 20. Such an arrangement can make the overall structure more regular, and can ensure the structural strength of the wind deflector 70, avoiding the wind deflector 70 from being dropped by blowing.

In an embodiment not shown in the figures, the wind deflector is placed transversely in the second wind channel, or the wind deflector is gradually lowered from the axis close to the fan to the axis far away from the fan, or the wind deflector is conical, and the conical end is provided as an air outlet.

In order to make the whole of the lamp more stable, as shown in fig. 3 and 6, in the present embodiment, the fan further includes a connecting piece 80, the connecting piece 80 is connected between the second air duct structure 32 and the base 10, and the connecting piece 80 and the air duct structure 30 are symmetrically disposed about the center of the fan 20. Specifically, the structural shape of the connection member 80 is the same as the shape of the first air duct structure 31. Therefore, the centrifugal force generated during rotation of the fan 20 can be effectively balanced, and the stability of the lamp is indirectly ensured.

As shown in fig. 1 and 2, in the present embodiment, the distance between the top of the second air duct structure 32 and the top of the base 10 is b1, and the diameter of the second air duct structure 32 is b2, where b1 and b2 satisfy that b2= (2-5) ×b1, and the width b3 of the air outlet 40 satisfies that b3 is less than or equal to 1mm and less than or equal to 3mm. The above ratio can make the air quantity larger. Specifically, b2=3b1, b3=2mm.

As shown in fig. 1, in the present embodiment, the first air duct structure 31 gradually decreases in height from near the blower 20 to near the second air duct structure 32. The above arrangement is more convenient for the flow of wind, and simultaneously, makes the air outlet 40 be closer to the user, and makes the experience effect of the user better.

As shown in fig. 1, in this embodiment, the fan further includes a driving device and a control device, which are located in the normal-pressure air region. The driving device and the control device can control the rotation of the fan 20, so that the lamp realizes the blowing function.

According to another aspect of the present application, there is provided a fan lamp, which includes a fan and a lamp body 50 disposed on the fan, wherein the fan is the above-mentioned fan. The air quantity of the fan is larger, the air blowing effect is better, and the using effect of a user can be effectively improved. Therefore, the fan lamp with the fan also has the functions.

In order to avoid the lamp body from being damaged, the fan further comprises a wind shield 70, the wind shield 70 is obliquely arranged, the wind shield 70 is connected to the lower portion of the second air duct structure 32, an air outlet 40 is formed between the wind shield 70 and the second air duct structure 32, and the lamp body 50 and the air outlet 40 are respectively located on the inner side and the outer side of the wind shield 70. The arrangement of the wind guard 70 can effectively separate wind from the lamp body 50, and further prevent the wind from directly blowing toward the lamp body 50, so that the lamp body 50 can be effectively protected and prevented from being damaged.
