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

The inventor finds that two air supply pipes are selected in the prior art, the air output is seemingly increased, the length of the Archimedes spiral air duct is greatly shortened, and the air supercharging effect is greatly influenced. Meanwhile, in the prior art, one-way circulating air supply is selected, so that air continuously moves in an ineffective circulating manner in the annular air duct, and finally the air quantity coming out through the air outlet is not much. The technical scheme of this application supplies air through a blast pipe, has expanded the length of Archimedes spiral duct, has promoted the pressure boost effect of wind. Meanwhile, the technical scheme of the embodiment selects to output two paths of wind with different wind directions simultaneously, looks like a wind direction conflict, actually increases the wind pressure through the opposite impact of the wind, and further increases the air output. Simultaneously, the simple structure of the fan of this embodiment need not additionally increase booster mechanism, need not make big change to product appearance, can show and promote the air supply effect.

The bladeless fan has unique modeling and air supply technology; and their hidden blade design, are becoming increasingly popular in the market place without covering dust or injuring the fingers of the child inserted. In the related art, the wind has only 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 the wind flows, so that the wind cannot be effectively blown to a user, and the problem is solved. As shown in fig. 1 and fig. 3 to 5, in the present embodiment, the fan includes: base member 10, fan 20, wind channel structure 30 and air outlet 40. The substrate 10 has a cavity 11. The fan 20 is installed in the cavity 11. The air duct structure 30 includes a first air duct structure 31 and a second air duct structure 32 communicated with the first air duct structure 31, and the first air duct structure 31 is communicated 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 communicated with each other, both the first air duct section 321 and the second air duct section 322 are communicated with the first air duct structure 31, and the flow direction of the air in the first air duct section 321 is opposite to the flow direction of the air in the second air duct section 322.

By applying the technical scheme of this embodiment, the fan 20 is disposed in the cavity 11, the air duct structure 30 includes a first air duct structure 31 and a second air duct structure 32, and the first air duct structure 31, the second air duct structure 32 and the cavity 11 are communicated and are located 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 directions of the gas in the first air channel section 321 and the second air channel section 322 are opposite. As can be seen from the above, the air blown out by the fan 20 flows to the communication position of the first air duct section 321 and the second air duct section 322 through the first air duct structure 31, and is divided at the communication position of 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 and flows in the first air duct section 321 and the second air duct section 322, and then flows out through the air outlet 40, so that the air volume can be effectively increased, and uneven air outlet can be avoided. Therefore, the technical scheme of the embodiment effectively solves the problem of poor user experience caused by small air volume 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 with each other, that is, strong convection wind is generated, so that the wind volume and the wind speed can be increased.

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 blown out by the fan can be fast enough, and further the air volume blown out by the lamp is large enough. If set up the air outlet of a plurality of fans 20, then can lead to the wind speed to reduce and then make the amount of wind reduce, user's experience is relatively poor.

In order to avoid the loss of the wind flow velocity, as shown in fig. 1 and 3, in the present embodiment, the axis of the first air duct structure 31 extends in a direction parallel to the radial direction of the fan 20, and the second air duct structure 32 is an annular structure. The arrangement can enable the air blown out by the fan 20 to flow into the first air channel section 321 and the second air channel section 322 respectively, and can enable the air to correspond to the air outlet of the fan 20 exactly, so that the consumption of the air blown out by the fan 20 can be effectively reduced, and the air quantity is ensured. Moreover, 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 channel structure extends in a radial direction of the fan, which also enables the fan to blow air into the first air channel structure. If the fan adopts axial fan, then first wind channel structure extends along the axial of fan, for the maximize of guaranteeing the amount of wind this moment, needs to make the extending direction of first wind channel structure and the axis collineation of fan.

As shown in fig. 1 and fig. 3, in the present embodiment, the first air duct structure 31 is a straight air duct, and the straight air duct is provided to facilitate the flow of air, so as to avoid the interference of the first air duct structure 31 on the flow of air.

In an embodiment not shown in the figures, the first air duct structure is a curved air duct. The bent 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 volume flowing into the first air duct section 321 is small, and further the air volume of each air outlet 40 is different, in order to avoid the above situation, the inventor has performed a lot of experiments, and a flared air guide structure 60 is disposed at the joint of the first air duct structure 31 and the second air duct structure 32. As shown in fig. 3, in this embodiment, the flared air guiding structure 60 is configured to effectively reduce the vortex generated at the joint between the first air duct structure 31 and the first air duct section 321 by the flowing air, so as to further ensure the flow velocity of the air, and further improve the air volume of the air flowing out through the air outlet 40, so as to enable the user experience to be better.

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

In order to prevent the blown air from being sucked into the air inlet, as shown in fig. 1 and 5, in the present embodiment, an air inlet 12 is provided on the base 10, the air inlet 12 is located above the fan 20, and a normal pressure air region is formed between the air inlet 12 and the fan 20. The air inlet 12 is disposed above the fan, and the screen structure is disposed at the air inlet 12, so that impurities can be prevented from entering the first air duct structure 31 and the second air duct structure 32. Meanwhile, because the air inlet 12 is arranged above the fan, namely above the air outlet 40, the blown air can be prevented from being sucked into the air inlet 12, and the blowing effect can be indirectly ensured.

It should be noted that the atmospheric air region is only referred to the pressurized air in the air duct structure 30. In practical applications, the air pressure in the normal pressure air region may be slightly lower than the ambient air pressure due to the resistance of the air inlet 12.

In order to avoid the wind from flowing back, that is, from flowing from the fan to the air inlet, as shown in fig. 1, in this embodiment, the base 10 is further provided with a backflow preventing baffle 13, the backflow preventing baffle 13 is located between the normal pressure air area and the fan 20, and the backflow preventing baffle 13 blocks the periphery of the air inlet of the fan 20. The anti-backflow baffle 13 separates a conventional air pressure area and a compressed air area (in the air channel structure 30) to prevent air from flowing back, and the fan 20 is matched with the Archimedes spiral air channel to form a strong convection air channel with high wind speed and high wind pressure.

In order to improve the effect of backflow prevention, as shown in fig. 1, in this embodiment, the backflow prevention baffle 13 includes a first shielding section and a second shielding section, the first shielding section is connected above the fan 20 at the first shielding section, and at least a part of the structure of the second shielding section extends into the air inlet of the fan 20. First sheltering from section and second and sheltering from the section cooperation, and then make the effect of sheltering from better, even between wind current to fan 20 and anti-reflux baffle 13, also can shelter from the effect of section through the second and flow back to in the air inlet of fan 20.

As shown in fig. 4 and 5, in the present embodiment, the fan 20 includes an impeller, a plurality of blades are spaced on the impeller, the diameter of the impeller is a1, and the distance between two adjacent blades close to the outer periphery of the impeller is a2, where a1 and a2 satisfy: a2 is (0.1-0.5) a 1. The above ratio relationship can obtain higher air pressure and wind speed. Specifically, in the present embodiment, a2 is 0.3a 1.

In order to avoid the wind shielding plate from being damaged by blowing, as shown in fig. 1 and fig. 2, in the present embodiment, the fan further includes a wind shielding plate 70, the wind shielding plate 70 is disposed obliquely, the wind shielding plate 70 is connected below the second air channel structure 32, and the air outlet 40 is formed between the wind shielding plate 70 and the second air channel structure 32. Because the wind deflector 70 is obliquely arranged, the size of the air outlet 40 is smaller than the sectional size of the second air duct structure 32, so that the wind can flow out through the air outlet 40, the flow rate of the wind can be increased, and the wind can be blown to a longer distance. In particular, the wind deflector 70 is an arc, which also enables the wind deflector 70 to guide the wind, avoiding direct blows of the wind.

As shown in fig. 1 and 2, in the present embodiment, the wind deflector 70 gradually rises from near the axis of the fan 20 to far from the axis of the fan 20. Such setting can make holistic structure more regular to can guarantee deep bead 70's structural strength, avoid deep bead 70 to be blown and drop.

In the embodiment not shown in the figure, the wind deflector is transversely arranged in the second air duct, or the wind deflector gradually decreases from the direction close to the axis of the fan to the direction far away from the axis of the fan, or the wind deflector is in a conical shape, and the end part of the conical shape is provided as an air outlet.

In order to make the whole lamp more stable, as shown in fig. 3 and 6, in the present embodiment, the fan further includes a connecting member 80, the connecting member 80 is connected between the second air duct structure 32 and the base 10, and the connecting member 80 and the air duct structure 30 are symmetrically arranged about the center of the fan 20. Specifically, the structural shape of the connector 80 is the same as the shape of the first air duct structure 31. Therefore, the centrifugal force generated when the fan 20 rotates 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, wherein b1 and b2 satisfy: b2 ═ 2 to 5 × b 1; the width b3 of the air outlet 40 satisfies: b3 is more than or equal to 1mm and less than or equal to 3 mm. The above ratio enables the air volume to be larger. Specifically, b 2-3 b1 and b 3-2 mm.

As shown in fig. 1, in the present embodiment, the height of the first air duct structure 31 gradually decreases from the direction close to the fan 20 to the direction close to the second air duct structure 32. The air outlet 40 is closer to the user, so that the experience effect of the user is better.

As shown in fig. 1, in the present embodiment, the fan further includes a driving device and a control device, and the driving device and the control device are located in the atmospheric 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, including a fan and a lamp body 50 disposed on the fan, wherein the fan is the fan. The fan is larger in air volume and better in blowing effect, and the using effect of a user can be effectively improved. Therefore, the fan lamp with the fan has the functions.
