In an embodiment, the upper half of the housing part 111 is provided in a closed manner to form the shielding part 115, and the lower half of the housing part 111 is provided with the air inlet 112. It can be understood that when the fan 10 is in the cold air mode, air can be fed not only from the air inlet end of the screen 110, but also from the air inlet 112 at the lower half of the housing portion 111, and the air inlet end of the screen 110 and the two air inlets of the air inlet 112 are beneficial to increasing the air inlet amount of cold air and ensuring the air speed of the cold air so as to ensure that the fan 10 has a better cold air effect, when the fan 10 is in the warm air mode, the air is heated after entering the screen 110, the density of hot air is small, the weight is light and the hot air rises upwards, and because the upper half of the screen 111 is in a closed arrangement, the hot air in the screen 110 cannot directly pass through the upper half of the screen portion 111 and upwards flow out, so that the loss of heat is avoided, and the hot air can only be blown out from the air outlet end of the screen portion 110 along with the rotation of the fan blades 120, so that the effect of the warm air is beneficial to ensure that the upper half of the housing portion 111 can also block part of the cold air from entering the screen 110, so that the doped cold air in the warm air mode is reduced, and further the fan 10 has a better warm air effect.

In one embodiment, the mesh enclosure 110 is rotatably coupled to the bracket assembly 200. The arrangement is that the mesh enclosure 110 can drive the fan head 100 to rotate integrally by arranging the bracket assembly 200, so that the shaking effect of the fan head 100 is realized, wherein the mesh enclosure 110 can rotate up and down or left and right, that is, the fan head 100 can rotate up and down and/or left and right.

Referring to fig. 2 to 5, in an embodiment, the mesh enclosure 110 has an air inlet end and an air outlet end opposite to each other, the air inlet 112 and the shielding portion 115 are disposed between the air inlet end and the air outlet end, the heating element 130 is disposed between the fan blade 120 and the air inlet end, and at least a part of the projection of the fan blade 120 in the vertical direction falls into the air inlet 112.

It can be understood that the heating element 130 is disposed on the air inlet side of the fan blade 120, that is, when the fan blade 120 rotates, cold air is sucked from the air inlet end of the mesh enclosure 110, heated by the heating element 130 and changed into hot air, and then blown out from the air outlet end of the mesh enclosure 110 along with the rotation of the fan blade 120, and the hot air is scattered by the rotation of the fan blade 120, so that the blown hot air is uniform, and the comfort level of the user is improved.

Further, the air inlet 112 and the shielding portion 115 are disposed between the air inlet end and the air outlet end, and during the cold air mode, cold air can be fed from the air inlet 112 in addition to the air inlet end of the mesh enclosure 110, so that the air inlet quantity of the cold air can be complemented to ensure the air outlet quantity of the cold air, and the fan 10 has a better cold air effect. In addition, during heating mode, cold air is mainly fed from the air inlet end, air entering from the air inlet end is discharged after being heated by the heating element 130, the rotating speed of the fan blades 120 is reduced under the heating mode, less air enters from the air inlet 112, the shielding part 115 can also block airflow, the lateral cold air entering of the mesh enclosure 110 is further reduced, namely cold air doped in warm air is reduced, so that less cold air is blown out from the air outlet end of the mesh enclosure 110, and the fan 10 has a better warm air effect.

Further, at least part of the fan blades 120 fall into the air inlet 112 in the vertical projection, so that the air entering from the air inlet 112 can be directly scattered by the rotating fan blades 120, thereby reducing the wind resistance of the part of air and reducing the noise generated by the reversing of the part of air. Therefore, the projection of at least part of the fan blades 120 falling down in the air inlet 112 is beneficial to reducing the noise generated by the fan 10 while increasing the air intake, so that the applicability of the fan 10 is improved.

In an embodiment, a projection of an end of the fan 120 near the heat generating component 130 in an up-down direction falls into the air inlet 112. By the arrangement, all air entering from the air inlet 112 can be scattered by the rotating fan blades 120 and then blown out from the air outlet end of the net cover 110, so that the wind resistance of the air entering from the air inlet 112 is further reduced, and the noise generated by reversing the air is reduced.

In an embodiment, a projection of an end of the heat generating element 130 away from the fan blade 120 in the up-down direction falls outside the air inlet 112. With this arrangement, the air entering from the air inlet 112 is prevented from directly blowing to the heat generating member 130 to generate noise.

Referring to fig. 4, in order to ensure a better warm air effect of the fan 10, in an implementation, a distance between the heat generating element 130 and the fan blade 120 in an axial direction of the fan blade 120 is D1, where D1 is greater than or equal to 10mm and less than or equal to 25mm. It will be appreciated that when the distance between the heat generating element 130 and the fan blade 120 is relatively short, the high temperature generated by the heat generating element 130 may cause the fan blade 120 to deform, and when the distance between the heat generating element 130 and the fan blade 120 is relatively long, the warm air effect of the fan 10 may be affected.

Referring to fig. 4, in order to reduce noise of the fan 10, in an embodiment, the air inlet 112 has a first edge far from the air inlet end, a distance between an end of the fan blade 120 near the heat generating element 130 and the first edge in an axial direction of the fan blade 120 is D2, and a height of the fan blade 120 along the axial direction is H, where 5mm is equal to or less than D2 is equal to or less than H.

It can be appreciated that by limiting the size of D2, it can be ensured that a part of the fan blades 120 or all of the fan blades 120 fall into the air inlet 112 in a downward projection manner, and according to the foregoing, the air entering along the radial direction of the fan blades 120 and passing through the air inlet 112 can be dispersed by the rotating fan blades 120 and then blown out from the air outlet end of the mesh enclosure 110, so that the wind resistance of the air entering from the air inlet 112 can be reduced, and the noise generated by reversing the air can be reduced. D2 may be 5mm, or 8mm, or 10mm, or 15mm, or the like, and specifically may be set according to the height H of the fan blade 120 in the axial direction thereof, which is not limited herein.

Referring to fig. 3 to 6, in an embodiment, the fan 10 further includes a heat insulation member 300, and the heat insulation member 300 is disposed in the mesh enclosure 110 and sleeved outside the heat generating member 130 along the axial direction of the fan blade 120.

It is understood that the heat insulating member 300 may be disposed in a ring shape, and the heat insulating member 300 is used to insulate heat generated by the heat generating member 130, so as to prevent heat from being transferred to the mesh enclosure 110. Particularly, when the rotation of the fan blade 120 is stopped due to a fault or the rotation speed of the fan blade 120 is reduced, if the heat insulation member 300 is not arranged in the case of working failure of the fan 10, the heat of the heating member 130 is transferred to the mesh enclosure 110 or an object outside the mesh enclosure 110, so that fire and other safety accidents are caused. In this embodiment, the center line of the heat insulating member 300 coincides with the rotation axis of the fan blade 120, which is advantageous for improving the uniformity of the fan 10.

In addition, the heat insulating member 300 also has a function of collecting heat, and when the heat generating member 130 heats the air, the heat generated by the heat generating member 130 is collected by the heat insulating member 300 to prevent the heat from being diffused arbitrarily, and the fan blades 120 rotate to take away the collected heat, so that the heating effect of the fan 10 is improved. And, through setting up thermal-insulated piece 300, the heat on the screen panel 110 is lower to make the screen panel 110 can adopt the material of the heat resistance that is less than thermal-insulated piece 300, because the material quantity of screen panel 110 is greater than the material quantity of thermal-insulated piece 300, the screen panel 110 adopts the material that the heat resistance is low, is favorable to reducing fan 10's manufacturing cost.

Referring to fig. 4, in an embodiment, the distance between the heat generating element 130 and the heat insulating element 300 in the radial direction of the fan blade 120 is D3, where 5mm < D3 < 25mm. It can be understood that when the distance between the heat generating element 130 and the heat insulating element 300 is relatively short, the heat insulating element 300 can affect the smoothness of air flow, and when the distance between the heat generating element 130 and the fan blade 120 is relatively long, the heat insulating and heat collecting effects of the fan 10 can be affected. Wherein D3 may be 5mm, or 10mm, or 12mm, or 15mm, or 18mm, or 20mm, or 22mm, or 25mm, etc., and is specifically not limited herein.
