Referring to fig. 2, 3 and 4, the air supply mechanism 1 includes a fan assembly 10, an air supply driving assembly 20 and an angle adjusting assembly 30, wherein the air supply driving assembly 20 and the angle adjusting assembly 30 are both coupled to the fan housing, the fan assembly 10 includes a base 11 and a fan 12 disposed on the base 11, the fan 12 has a transmission portion 122, the air supply driving assembly 20 is in transmission connection with the fan assembly 10 and is used for driving the fan assembly 10 to rotate around a first rotation axis, the angle adjusting assembly 30 includes a first transmission member 31 engaged with the transmission portion 122, and the first transmission member 31 is controlled to drive the fan 12 to rotate around a second rotation axis relative to the base 11; wherein the extending direction of the first rotation axis (e.g., X direction in fig. 2) intersects with the extending direction of the second rotation axis.

The included angle between the extending direction of the first rotation axis and the extending direction of the second rotation axis may be an acute angle, a right angle, an obtuse angle, or the like. The following embodiments will each be described taking the first rotation axis as the central axis of the base 11 and the second rotation axis as the radial line of the base 11 as an example.

The fan blade assembly 10 includes a plurality of fan blades 12, and the plurality of fan blades 12 are arranged at intervals along the circumferential direction of the base 11. Each fan blade 12 comprises a fan blade main body 121, a fan blade connecting shaft and a transmission part 122, wherein the fan blade main body 121 and the transmission part 122 are arranged at two ends of the fan blade connecting shaft, and the fan blade connecting shaft extends along the extending direction of the second rotation axis.

When the air supply driving assembly 20 works, the base 11 and each fan blade 12 synchronously rotate around the first rotation axis, so that the air supply mechanism 1 can drive air flow to flow and realize air supply. When the angle adjusting assembly 30 works, each fan blade 12 rotates relative to the base 11 around the second rotation axis, so that the angle of each fan blade 12 relative to the base 11 is changed, the blowing force can be adjusted, the air outlet is soft and dispersed, and the user experience degree of the air supply device are improved.

It should be noted that, because the setting positions of the different fan blades 12 are different, the extending directions of the second rotation axes around which the different fan blades 12 rotate are also different, and only the extending directions of the second rotation axes around which each fan blade 12 rotates and the extending directions of the first rotation axes need to be ensured to intersect.

In some embodiments of the present application, the first transmission member 31 and the transmission portion 122 are gears, and the first transmission member 31 can be controlled to rotate around the second rotation axis to drive the transmission portion 122 to rotate.

In some embodiments of the present application, the transmission part 122 is a gear, and the first transmission member 31 is configured to be formed with a rack 311 extending in an extending direction of the first rotation axis, the rack 311 being engaged with the gear; when the first transmission member 31 is controlled to reciprocate along the extending direction of the first rotation axis, the fan blade 12 rotates relative to the base 11.

The number of racks 311 is the same as the number of the fan blades 12 and corresponds to one another, and each rack 311 extends along the extending direction of the first rotation axis and is meshed with the corresponding gear on the fan blade 12.

In the process that the first transmission member 31 is controlled to reciprocate along the direction of the first rotation axis, each rack 311 reciprocates along the direction of the first rotation axis, and drives the corresponding gear to drive the fan blade connecting shaft and the fan blade main body 121 to rotate around the second rotation axis.

By providing the rack 311 and the gear, a linear motion of the rack 311 along the first rotation axis may be converted into a rotational motion of the fan blade 12 about the second rotation axis. With this design, the layout between the first transmission member 31 and the fan blade assembly 10 is more compact, thereby contributing to the miniaturization of the blower mechanism 1.

In some embodiments of the present application, the angle adjustment assembly 30 further includes an adjustment driving member 32 and a second transmission member 33, wherein the second transmission member 33 is in transmission connection between the adjustment rotating shaft 322 of the adjustment driving member 32 and the first transmission member 31, and the adjustment driving member 32 is located outside the base 11; the second transmission member 33 is configured to convert the rotational movement of the adjustment shaft 322 into a linear movement of the first transmission member 31 away from the adjustment driving member 32.

The adjusting shaft 322 extends along a direction intersecting with the first rotation axis, and an extending direction of the adjusting shaft 322 may be the same as an extending direction of a fan blade connecting shaft of one of the fan blades 12 or may be different from an extending direction of each fan blade connecting shaft.

The adjusting driving member 32 further includes an adjusting body 321, the adjusting body 321 is connected with the fan housing, the adjusting shaft 322 is coupled to the adjusting body 321, and the adjusting body 321 drives the adjusting shaft 322 to rotate, so that the second transmission member 33 can convert the rotational movement of the adjusting shaft 322 into the linear movement of the first transmission member 31 away from the adjusting driving member 32. Furthermore, the first transmission member 31 drives the transmission portion 122 to drive the fan blade body 121 to rotate relative to the base 11.

By providing the adjustment driving member 32 and the second transmission member 33, the layout inside the angle adjustment assembly 30 is more compact, thereby contributing to the miniaturization of the blower mechanism 1.

Referring to fig. 3 and 4 again, and referring to fig. 5 at the same time, in some embodiments of the present application, the second transmission member 33 includes a crankshaft 331, a connecting rod 332, and a pushing member 333, opposite ends of the connecting rod 332 are respectively rotatably connected with the pushing member 333 and the crankshaft 331, one end of the crankshaft 331 away from the connecting rod 332 is fixedly connected with the adjusting shaft 322, and one end of the pushing member 333 away from the connecting rod 332 is abutted against one side of the first transmission member 31; the connecting rod 332 and the crankshaft 331 cooperate to convert the rotational motion of the adjustment shaft 322 into a linear motion of the pushing member 333 and the first transmission member 31 away from the adjustment driving member 32.

For example, in some embodiments, the pushing member 333 may include a pushing plate 3331 and a pushing shaft 3332 protruding from a side of the pushing plate 3331 facing away from the first transmission member 31, where the pushing shaft 3332 is connected to the connecting rod 332. Alternatively, in some embodiments, the pushing member 333 may further include a pushing plate 3331, a pushing shaft 3332 protruding from a side of the pushing plate 3331 opposite to the first transmission member 31, and a connecting post 3332, wherein one end of the connecting post 3332 is fixedly connected with the pushing shaft 3332, and one end of the connecting rod 332 away from the crankshaft 331 is rotatably connected with one end of the connecting post 3332 away from the pushing shaft 3332. The structure of the pushing member 333 is not limited to the above, and it may be provided as needed.

When the adjusting shaft 322 rotates in the forward direction, the crankshaft 331 and the connecting rod 332 are synchronously driven to rotate, and the pushing member 333 is pushed by the connecting rod 332 to slide along the extending direction of the first rotation axis and away from the adjusting driving member 32. The pushing member 333 abuts against the first transmission member 31, and the first transmission member 31 can also slide away from the adjustment driving member 32 under the action of the pushing member 333. When the adjusting shaft 322 rotates reversely, the crankshaft 331 and the connecting rod 332 are driven to rotate, and further, the pushing member 333 is slidable in the extending direction of the first rotation axis and toward the adjustment drive 32 by the pushing of the link 332. Since the pushing member 333 is abutted against the first transmission member 31, the pushing member 333 does not drive the first transmission member 31 to move during the sliding process of the pushing member 333 toward the adjustment driving member 32. That is, the pushing member 333 provides only the power for the first transmission member 31 away from the adjustment driving member 32. During the sliding of the first transmission member 31 away from the adjustment driving member 32, each fan blade 12 rotates and changes angle with respect to the base 11.

By arranging the crankshaft 331, the connecting rod 332 and the pushing component 333, the first transmission member 31 is matched with the pushing component 333, so that the sliding of the first transmission member 31 away from the adjustment driving member 32 is simple and easy to operate.

In some embodiments of the present application, the air blowing mechanism 1 further includes a guide tube 50 extending along the extending direction of the first rotation axis, and the pushing member 333 partially extends into the guide tube 50 and moves linearly with respect to the guide tube 50.

The guide tube 50 is connected to the fan housing, and the guide tube 50 is fixed in position during the operation of the adjustment drive member 32.

In embodiments where the pushing member 333 includes a push plate 3331 and a pushing shaft 3332, the pushing shaft 3332 extends into the guide tube 50. In the embodiment where the pushing member 333 includes a push plate 3331, a pushing shaft 3332 and a connecting column 3332, the pushing shaft 3332 and the connecting column 3332 both extend into the guide tube 50 and extend along the extending direction of the guide tube 50.

By providing the guide tube 50, the guide tube 50 can guide the pushing member 333 to slide, and can prevent the pushing member 333 from shaking during the linear motion, thereby ensuring the stability of the linear motion of the pushing member 333 and the first transmission member 31.

In some embodiments of the present application, the angle adjustment assembly 30 further includes an elastic member 40, the elastic member 40 is abutted between the side of the first transmission member 31 facing away from the pushing member 333 and the base 11, and the elastic member 40 is configured to deform and store elastic potential energy in the movement of the first transmission member 31 away from the adjustment driving member 32; when the elastic member 40 releases the elastic potential energy, the elastic member 40 drives the first transmission member 31 to drive the pushing member 333 to move toward the adjustment driving member 32.

The elastic member 40 may be a spring, a high elastic rubber, or other members.

When the fan blade 12 does not rotate relative to the base 11, the elastic force of the elastic member 40 is the same as the torque force applied to the first transmission member 31 by the adjusting driving member 32 through the second transmission member 33, and the directions are opposite. At this time, the elastic force of the elastic member 40 and the torsion force applied by the adjustment driving member 32 are smaller. When the angle of the fan blade 12 needs to be changed, the torque force applied by the adjustment driving member 32 is increased, so that the first transmission member 31 can be moved away from the adjustment driving member 32 under the pushing of the pushing member 333, and further, the fan blade 12 rotates relative to the base 11, and the elastic member 40 is further compressed. After the angle adjustment is finished, the fan blade 12 is maintained at a fixed angle and is kept stationary relative to the base 11. When the angle of the fan blade 12 needs to be reset to the angle before being changed, the adjusting spindle 322 of the adjusting driving member 32 rotates reversely, so that the pushing member 333 can move towards the adjusting driving member 32 under the action of the connecting rod 332 and the crankshaft 331, and at the same time, the elastic member 40 releases elastic potential energy and drives the first transmission member 31 to move towards the adjusting driving member 32, the transmission portion 122 reverses and resets angularly, and in this process, the first transmission member 31 and the pushing member 333 are always pressed against and can also drive the pushing member 333 to move towards the adjusting driving member 32.

By arranging the elastic piece 40, the fan blade 12 can be automatically reset, thereby being beneficial to improving the resetting simplicity.

In some embodiments of the present application, the first transmission member 31 is provided with a through hole 312 penetrating the first transmission member along the extending direction of the first rotation axis, the air supply driving assembly 20 further includes an air supply driving member 21, the air supply rotating shaft 212 of the air supply driving member 21 slidably penetrates the first transmission member 31, and the air supply driving member 21 is used for driving the first transmission member 31 to drive the fan blade assembly 10 to rotate around the first rotation axis.

The air supply driving member 21 further includes an air supply main body 211, and the air supply main body 211 and the fan housing, and the air supply rotating shaft 212 penetrates through the push plate 3331 along the extending direction of the first rotation axis and is in transmission connection with the first transmission member 31. When the air supply main body 211 drives the air supply shaft 212 of the air supply driving member 21 to rotate, the first transmission member 31 can drive the transmission part 122 to drive the fan blade main body 121 and the base 11 to rotate around the first rotation axis, so as to realize air supply.

The first transmission member 31 is driven by the air supply driving assembly 20 to drive the fan blade assembly 10 to rotate around the first rotation axis, so that the structure of the air supply mechanism 1 is more compact.

In actual operation, the first transmission member 31 is fixed to the air supply driving member 21 in the process of moving linearly along the extending direction of the first rotation axis and driving the fan blade 12 to rotate relative to the base 11, and the first transmission member 31 moves linearly relative to the air supply shaft 212, so that when the air supply driving member 21 works, the first transmission member 31 can drive the fan blade 12 and the base 11 to rotate synchronously under the action of the air supply driving member 21.

By providing the protruding portion 313 and the recessed portion 213, the axial sliding of the first transmission member 31 with respect to the blower driving member 21 is satisfied, and the first transmission member 31 can be ensured to rotate under the action of the blower driving member 21, so that the blower device can reliably operate.

In some embodiments of the present application, the adjusting body of the adjusting driving member is fixedly connected with the fan housing through the bracket 60 and the air supply body 211 of the air supply driving member 21.

In some embodiments of the present application, the air supply mechanism 1 further includes an avoidance pipe 80, where the avoidance pipe 80 extends along the extending direction of the first rotation axis, and the avoidance pipe 80 is sleeved outside the air supply rotating shaft 212 and is connected with the air supply main body 211. In addition, the guide duct 50 is connected to the bypass duct 80 through a connector, so that the guide duct 50 can be connected to the fan housing through the connector, the bypass duct 80 and the air supply main body 211 in this order. In such an embodiment, the guide tube 50 is more stable and secure to provide better guidance.

In some embodiments of the present application, the base 11 is a hollow structure with an opening 111 at one end, the fan blade 12 is disposed through a side wall of the base 11 along the extending direction of the second rotation axis, and the transmission part 122 is located in the base 11; the first transmission member 31 is disposed through the opening 111 of the base 11, and is partially disposed in the base 11 and engaged with the transmission portion 122.

In addition, the elastic member 40 is also accommodated in the base 11 and is pressed between the inner wall of the base 11 facing the opening 111 and the first transmission member 31.
