It should be noted that the embodiments of the present disclosure and the features in the embodiments can be combined with each other if there is no conflict.

In the following description, numerous specific details are set forth in order to provide a thorough understanding of the present disclosure. However, the present disclosure can also be implemented in other manners than those described herein. Therefore, the protection scope of the present disclosure is not limited to the specific embodiments disclosed below.

A fan 100 proposed according to some embodiments of the present disclosure is described below with reference to FIGS. 2 to 4.

Embodiment 1

As shown in FIG. 2, according to an embodiment of the present disclosure, the present disclosure proposes a fan 100, comprising: a column assembly 102, a fan head 104, a hinge assembly 106, and a support structure 108.

Specifically, the hinge assembly 106 comprises a first connection member 1060 and a second connection member 1061 which are hinge-connected to each other, the first connection member 1060 is connected to the column assembly 102, and the second connection member 1061 is connected to the fan head 104; and the support structure 108 is connected to the fan head 104 and the column assembly 102, wherein the fan head 104 is adapted to rotate around the support structure 108, and an axis around which the fan head 104 rotates relative to the support structure 108 coincides with an axis around which the first connection member 1060 and the second connection member 1061 rotate relative to each other.

The fan 100 provided in the present disclosure comprises a column assembly 102 and a fan head 104, the fan head 104 and the column assembly 102 are connected by a hinge assembly 106 and a support structure 108, wherein a first connection member 1060 and a second connection member 1061 of the hinge assembly 106 are hinge-connected to each other, i.e., the first connection member 1060 and the second connection member 1061 can rotate relative to each other, the fan head 104 is adapted to rotate around the support structure 108, and an axis around which the fan head 104 rotates around the support structure 108 coincides with an axis around which the first connection member 1060 and the second connection member 1061 rotate relative to each other, so that the fan head 104 can rotate around the axis around which the first connection member 1060 and the second connection member 1061 rotate relative to each other, i.e., the fan head 104 can rotate around the column assembly 102, thereby realizing adjustment of an air outlet angle of the fan head 104. Further, the support structure 108 connects the fan head 104 and the column assembly 102, which improves the reliability of connection between the fan head 104 and the column assembly 102, and also enables the fan 100 to have a better appearance, and therefore improves use experience of the user.

Specifically, the hinge assembly 106 comprises a first connection member 1060 and a second connection member 1061 which are hinge-connected to each other. The first connection member 1060 and the second connection member 1061 respectively connect the fan head 104 and the column assembly 102 so that the fan head 104 can rotate around the column assembly 102.

Moreover, the fan head 104 and the column assembly 102 are also connected by the support structure 108. On the one hand, the axis around which the fan head 104 rotates around the support structure 108 coincides with the axis around which the first connection member 1060 and the second connection member 1061 rotate relative to each other, so that the fan head 104 and the column assembly 102 can still rotate under the connection by the two structures, i.e., the hinge assembly 106 and the support structure 108; and on the other hand, the support structure 108 connects the fan head 104 and the column assembly 102, so that when the hinge assembly 106 fails, the fan head 104 and the column assembly 102 can still be connected by the support structure 108 to prevent the fan head 104 from falling, which improves the strength of connection between the fan head 104 and the column assembly 102 and increases the reliability of the fan 100, and also, when the fan head 104 is adjusted to a certain angle, the fan head 104 can be supported by the support structure 108, ensuring the reliability of the fan head 104.

Specifically, the support structure 108 may be ring-shaped, such that the center of circle of the support structure 108 coincides with the axis around which the first connection member 1060 and the second connection member 1061 rotate relative to each other.

Embodiment 2

An embodiment according to the present disclosure includes the features defined in the above embodiment, and further, the axis around which the first connection member 1060 and the second connection member 1061 rotate relative to each other is perpendicular to a length direction of the column assembly 102.

In this embodiment, the axis around which the first connection member 1060 and the second connection member 1061 rotate relative to each other is perpendicular to the length direction of the column assembly 102, thus realizing adjustment of an angle of depression and an angle of elevation of the fan head 104, thereby expanding an air outlet area of the fan 100.

Specifically, since the axis around which the fan head 104 rotates around the support structure 108 coincides with the axis around which the first connection member 1060 and the second connection member 1061 rotate, the axis around which the fan head 104 rotates around the support structure 108 is also perpendicular to the length direction of the column assembly 102.

Specifically, the fan 100 may be a floor fan, and therefore the column assembly 102 is placed in a vertical direction, i.e., the length direction of the column assembly 102 is the vertical direction.

Of course, the axis around which the first connection member 1060 and the second connection member 1061 rotate relative to each other can also be parallel to the column assembly 102, so that the rotation action of left-right head shaking of the fan head 104 can be achieved.

Embodiment 3

As shown in FIGS. 3 and 4, an embodiment according to the present disclosure includes the features defined in the above embodiments, and further, the fan 100 further comprises: a limit member provided at the fan head 104 and/or the column assembly 102, wherein the limit member is adapted to limit rotation of the fan head 104 between a first position 114 and a second position 116.

In this embodiment, the fan 100 further comprises a limit member, and by providing the limit member, the range of rotation of the fan head 104 can be limited, such that the fan head 104 rotates between the first position 114 and the second position 116.

Specifically, the limit member may be provided at the fan head 104 or on the column assembly 102. Of course, both the fan head 104 and the column assembly 102 can be provided with the limit member.

Specifically, during the rotation of the fan head 104, the angle of rotation of the fan head 104 can be limited by the limit member resisting the fan head 104 or the column assembly 102.

Further, an angle by which the fan head 104 rotates from a horizontal position 112 towards below the fan 100 to the first position 114 is greater than or equal to 0° and smaller than or equal to 6°, and an angle by which the fan head 104 rotates from the horizontal position 112 towards above the fan 100 to the second position 116 is greater than or equal to 0° and smaller than or equal to 90°, wherein the horizontal position 112 is between the first position 114 and the second position 116, the fan head 104comprises a drive shaft 110 and fan blades connected to the drive shaft 110, and when the fan head 104 is located at the horizontal position 112, an axis of the drive shaft 110 is perpendicular to the length direction of the column assembly 102.

In this embodiment, as shown in FIGS. 3 and 4, the horizontal position 112 is between the first position 114 and the second position 116, and the fan head 104 can move from the horizontal position 112 to the first position 114 and the second position 116 respectively. When the fan head 104 is in the horizontal position 112, the axis of the drive shaft 110 is perpendicular to the length direction of the column assembly 102. That is, when the fan head 104 is in the horizontal position 112, the air outlet direction of the fan 100 is horizontal or approximately horizontal. The adjustment of the angle of depression and the angle of elevation of the fan head 104 can be realized through the hinge assembly 106 and the support structure 108. FIG. 3 is a schematic diagram when the fan head 104 moves to the first position 114. The angle by which the fan head 104 rotates from the horizontal position 112 towards below the fan 100 to the first position 114 is greater than or equal to 0° and smaller than or equal to 6°, i.e., the angle of depression of the fan head 104 moving downward from the horizontal position 112 is greater than or equal to 0° and smaller than or equal to 6°. FIG. 4 is a schematic diagram when the fan head 104 moves to the second position 116. The angle by which the fan head 104 rotates from the horizontal position 112 towards above the fan 100 to the second position 116 is greater than or equal to 0° and smaller than or equal to 90°, i.e., the angle of elevation of the fan head 104 moving upward from the horizontal position 112 is greater than or equal to 0° and smaller than or equal to 90°. That is, the fan head 104 can achieve an angle of depression of 6° and an angle of elevation of 90°, which expands the blowing range of the fan 100.

Specifically, the first position 114 is below the horizontal position 112 and the second position 116 is above the horizontal position 112.

Specifically, the fan 100 comprises a motor, and the motor is provided with a drive shaft 110 connected to the fan blades.

Further, the limit member on the fan head 104 is arranged at one side of the fan head 104 close to the support structure 108, and the limit member on the column assembly 102 is arranged at one side of the column assembly 102 close to the support structure 108.

In this embodiment, the limit member is arranged close to the support structure 108, so that the angle of rotation of the hinge assembly 106 can be limited at one side of the support structure 108.

Embodiment 4

As shown in FIG. 2, an embodiment according to the present disclosure includes the features defined in the above embodiments, and further, the hinge assembly 106 further comprises: a rotation shaft 1062 at which the first connection member 1060 and the second connection member 1061 are arranged, the second connection member 1061 being adapted to rotate around the rotation shaft 1062, wherein in an axis direction of the rotation shaft 1062, the second connection member 1061 is arranged at one side of the first connection member 1060; and an adjustment member connected to the rotation shaft 1062 and adapted to press the second connection member 1061 in the axis direction of the rotation shaft 1062.

In this embodiment, the hinge assembly 106 further comprises a rotation shaft 1062 and an adjustment member, and in the axis direction of the rotation shaft 1062, the second connection member 1061 is located at one side of the first connection member 1060, that is, the second connection member 1061 is located at the outer side of the first connection member 1060, so that the first connection member 1060 and the second connection member 1061 can be sequentially mounted at the rotation shaft 1062, which improves the assembly efficiency of the product and enhances the reliability of the product. Moreover, the first connection member 1060 can avoid the second connection member 1061 when the second connection member 1061 rotates, thus enabling the second connection member 1061 to have a greater angle of rotation to meet different use scenarios. The hinge assembly 106 further comprises an adjustment member connected to the rotation shaft 1062 and adapted to press the second connection member 1061 in the axis direction of the rotation shaft 1062, thus adjusting the axial pressure on the second connection member 1061 to improve the reliability of the hinge assembly 106.

Specifically, the adjustment member presses the second connection member 1061 in the axis direction of the rotation shaft 1062, and the magnitude of the axial pressure on the second connection member 1061 can be adjusted. The greater the axial pressure on the second connection member 1061, the greater the resistance to the rotation of the second connection member 1061, and thus the greater the force required to enable it to rotate around the rotation shaft 1062. Therefore, the magnitude of the force required to rotate the second connection member 1061 can be adjusted by the adjustment member. Further, by adjusting the axial pressure on the second connection member 1061, the friction between the second connection member 1061 and adjacent parts can be adjusted. That is, the greater the axial pressure on the second connection member 1061, the greater the friction between the second connection member 1061 and adjacent structures, and when the friction is able to counteract the force exerted on the second connection member 1061 that can cause it to rotate, the second connection member 1061 can be fixed in a designated position, so that the component connected to the second connection member 1061 is fixed in a designated position and will not rotate randomly, thereby improving the reliability of the hinge assembly 106. It may be understood that the resistance to the rotation of the second connection member 1061 includes the friction generated between the second connection member 1061 and the parts axially adjacent to the second connection member 1061.

Specifically, the first connection member 1060 and the second connection member 1061 can be sleeved sequentially on the rotation shaft 1062 in the direction of gravity, making the assembly convenient. Moreover, the distance between the first connection member 1060 and the second connection member 1061 in the axial direction of the rotation shaft 1062 can be adjusted at will, which improves the versatility of the hinge assembly 106.

Specifically, the first connection member 1060 can be rotated around the rotation shaft 1062, or the first connection member 1060 is fixed on the rotation shaft 1062.

Specifically, the first connection member 1060 is fixed on the rotation shaft 1062, and thus the rotation shaft 1062 can be fixed by the first connection member 1060.

Moreover, threaded connection is highly reliable, and when the tightening member 1063 is rotated to be removed from the rotation shaft 1062, the parts on the rotation shaft 1062 can be easily removed and replaced.

Specifically, the rotation shaft 1062 and the limiting structure provided at the end portion of the rotation shaft 1062 are a one-piece structure, the rotation shaft 1062 comprises a bolt or a screw, and the tightening member 1063 comprises a nut.

Further, the adjustment member further comprises: a damping member 1064 connected to the rotation shaft 1062, the damping member 1064 being arranged between the first connection member 1060 and the tightening member 1063, and/or between the second connection member 1061 and the first connection member 1060.

In this embodiment, the adjustment member further comprises a damping member 1064 connected to the rotation shaft 1062. The damping member 1064 can increase the resistance to the rotation of the second connection member 1061, so that the friction generated by the rotation of the second connection member 1061 is increased, and the force required to rotate the second connection member 1061 will also increase, thereby improving the stability of the hinge assembly 106. The damping member 1064 may be selectively arranged between the first connection member 1060 and the tightening member 1063 and between the second connection member 1061 and the first connection member 1060.

Specifically, the magnitude of the force required to rotate the second connection member 1061 may be adjusted by adding or reducing the damping member 1064. For example, it is feasible to increase the resistance to rotation of the second connection member 1061 by adding the damping member 1064, when the tightening member 1063 is screwed in the same position as the rotation shaft 1062, thereby increasing the force required to rotate the second connection member 1061, i.e., a greater force is required to rotate the second connection member. When the resistance to the rotation of the second connection member 1061 is greater than or equal to the force applied by another structure or a person to the second connection member 1061, the hinge assembly 106 can be kept in its current state, i.e., the second connection member 1061 is kept immobile, improving the stability of the hinge assembly 106.

Specifically, other structures than the hinge assembly 106 may be connected to the second connection member 1061. Said other structures include the fan head 104 of the fan 100 or the column assembly 102 of the fan 100, and may exert a force on the second connection member 1061 in the direction of rotation of the second connection member 1061. When the resistance to the rotation of the second connection member 1061 is greater than or equal to the force exerted by said other structures on the second connection member 1061, the hinge assembly 106 and said other structures mounted at the second connection member 1061 can be kept in their current state, thereby improving the stability of the second connection member 1061 and said other structures connected to the second connection member 1061.

Further, the damping member 1064 is a resilient pad, making it possible to adjust the force required to rotate the second connection member 1061.

Further, the adjustment member further comprises: a spacer 1065 connected to the rotation shaft 1062, the spacer 1065 being arranged between the second connection member 1061 and the limiting structure, and/or between the first connection member 1060 and the second connection member 1061, and/or between the first connection member 1060 and the tightening member 1063.

In this embodiment, the adjustment member further comprises a spacer 1065 which may be provided between two structures to improve the stability of connection. The spacer 1065 is arranged between the second connection member 1061 and the limiting structure, and/or between the second connection member 1061 and the first connection member 1060, and/or between the first connection member 1060 and the tightening member 1063. Moreover, the position and number of spacers 1065 and damping members 1064 may be set at will in the present disclosure, while the position and number of spacers are limited by the distance between two connection walls in the related art.

Specifically, in the axial direction of the rotation shaft 1062, the two ends of the spacer 1065 abut against other structures, that is, the spacer 1065 can press the structures on both sides, thus increasing the force required to rotate the structures on both sides of the spacer 1065, improving the stability of the hinge assembly 106.

Specifically, the parts of the rotation shaft 1062 that are connected to other structures than the second connection member 1061 and the tightening member 1063 on the hinge assembly 106 may all be provided with a limit surface correspondingly, and the shape of a mounting hole part where said other structures than the second connection member 1061 and the tightening member 1063 are connected to the rotation shaft 1062 is also adapted to the rotation shaft 1062, thus preventing said other structures from rotating, and improving the reliability of the structure.
