Description

Technical Field

[0001] The present application relates to the technical field of household appliances, and in particular to a head assembly and a fan. Background Art

[0002] Circulation fans are becoming more and more widely used because of their advantages such as more uniform air flow and energy and power saving.

[0003] In the related technology, the circulation fan compresses the air through the large-angle axial flow fan blades, and the air duct and the front net gather the air and then send it out of the fan. In order to ensure the air supply distance, the air supply range is small. In order to improve the air supply coverage and speed up the air circulation efficiency in the room, some circulation fans are designed with automatic shaking functions in the up and down and left and right directions. To achieve this function, most of them use two synchronous motors to control the shaking in two directions respectively. The internal wiring is complicated, and when the machine head is turned on to shake up and down and left and right at the same time, the internal wire body is easily bent or pulled at a large angle due to the large movement of the machine head, increasing the risk of wire core breakage or wire body wear.

[0043] See also Figures 1 to 5 , a head assembly 100 provided in one embodiment of the present application includes a bracket 10, a rotating connection member 20 and a head body 30. The rotating connection member 20 is connected to the bracket 10, and is configured to be able to rotate relative to the bracket 10 with a first axis 330 as a rotation axis. The head body 30 is connected to the rotating connection member 20, and is configured to be able to rotate relative to the rotating connection member 20 with a second axis 340 as a rotation axis, and the first axis 330 and the second axis 340 intersect or are not in the same plane. The bracket 10 has a first wiring groove 11 and a first wire hole 12, and the rotating connection member 20 has a second wiring groove 21 and a second wire hole 22. The first wire hole 12 connects the first wiring groove 11 and the second wiring groove 21, and the first axis 330 passes through the first wire hole 12, the second wire hole 22 connects the second wiring groove 21 and the interior of the head body 30, and the second axis 340 passes through the first wire hole 12.

[0044] The head assembly 100 is used for the fan 200, and the fan 200 can be but not limited to a circulation fan. The fan 200 also includes a body assembly 201, and the head assembly 100 is connected to the body assembly 201 through a bracket 10. It can be understood that in order to achieve its normal function, the head body 30 also includes a main motor 31, a fan blade 32, a cover 33, a back cover 34, a mesh cover 35, etc. Among them, the cover 33 is connected to the back cover 34 to form an installation cavity, and the main motor 31 is installed in the installation cavity. The main motor 31 is connected to the fan blade 32 in a transmission manner and is used to drive the fan blade 32 to rotate to form an air supply airflow. The mesh cover 35 is used to cover the outside of the fan blade 32 to prevent the user from directly contacting the fan blade 32. In addition, the head assembly 100 also includes a line 40, which can be arranged along the first wiring groove 11 and the second wiring groove 21, and extend into the head body 30.

[0045] The direction where the first axis 330 is located is the first direction (eg Figure 5 The direction in which the second axis 340 is located is the second direction (as shown in the X direction). Figure 1 The first axis 330 and the second axis 340 intersect or are not in the same plane, which means that the two are not parallel to each other, and the first direction and the second direction are in an intersecting relationship. It can be understood that the first axis 330 and the second axis 340 are both in the front-to-back direction of the head body 30 (such as Figure 5 The first direction, the second direction and the front-to-back direction of the head body 30 intersect with each other, that is, the first direction, the second direction and the front-to-back direction of the head body 30 intersect with each other, wherein the front-to-back direction of the head body 30 is the direction in which the air outlet of the head assembly 100 is oriented, and the front-to-back direction will change relative to the body assembly 201 as the head body 30 rotates. For ease of understanding, the following description is based on the example that the first direction and the second direction are perpendicular to each other, and when the air outlet of the head body 30 is oriented horizontally, its orientation is forward, and accordingly, one of the first direction and the second direction is the up-down direction, and the other is the left-right direction.

[0046] The head body 30 can rotate around a first axis 330 set along a first direction as a rotating axis, and can also rotate around a second axis 340 set along a second direction as a rotating axis, so as to realize the head body 30 shaking in at least two directions.

[0047] In the above-mentioned head assembly 100, the line 40 can be routed along the first wiring groove 11 and the second wiring groove 21, and finally reach the interior of the head body 30. Among them, the part of the line 40 in the first wiring groove 11 is relatively stable relative to the bracket 10, and the part in the second wiring groove 21 is relatively stable relative to the rotating connection 20. The relationship between the rotating connection 20 and the bracket 10 and the rotating connection 20 and the head body 30 is a rotation relationship around a single axis. Therefore, when the head body 30 shakes its head, the line 40 generally only has a small coaxial twist at the first wire hole 12 and the second wire hole 22, and will not be pulled significantly or bent at a large angle. In this way, while the head assembly 100 shakes its head, the line 40 passing through it will not be pulled significantly or bent at a large angle, the risk of wire core breakage or wire body wear is effectively reduced, and it helps to increase the service life of the line 40.

[0048] In some embodiments, the head assembly 100 has a first rotating shaft structure 23, the first rotating shaft structure 23 is extended along the direction of the first axis 330, the bracket 10 and the rotating connecting member 20 are relatively rotated through the first rotating shaft structure 23, and the first wire hole 12 is provided in the first rotating shaft structure 23;

[0049] And / or, the head assembly 100 also has a second rotating shaft structure 24, which is extended along the direction of the second axis 340, and the head body 30 and the rotating connecting member 20 realize relative rotation through the second rotating shaft structure 24, and the second wire hole 22 is provided in the second rotating shaft structure 24.

[0050] It can be understood that the rotating connection between the rotating connection member 20 and the bracket 10 and between the rotating connection member 20 and the head body 30 can be realized by the shaft hole matching. Among them, the bracket 10 and the rotating connection member 20 realize the rotation connection around the first axis 330 through the first rotating shaft structure 23, and the first rotating shaft structure 23 is extended along the first direction; the rotating connection member 20 and the head body 30 realize the rotation connection around the second axis 340 through the second rotating shaft structure 24, and the second rotating shaft structure 24 is extended along the second direction.

[0051] The first wire-passing hole 12 is formed on the first shaft structure 23 and can pass through the first shaft structure 23. The second wire-passing hole 22 is formed on the second shaft structure 24 and can pass through the second shaft structure 24. The line 40 can directly pass through the first shaft structure 23 along the first wire-passing hole 12 and enter the second wire routing groove 21 from the first routing groove 11. It can also directly pass through the second shaft structure 24 along the second wire-passing hole 22 and enter the interior of the head body 30 from the second routing groove 21.

[0052] In this way, on the one hand, the line 40 can be constrained and protected by the first rotating shaft structure 23 and the second rotating shaft structure 24, and on the other hand, the line 40 passes through the first rotating shaft structure 23 and the second rotating shaft structure 24, and is less affected by the rotation between the bracket 10 and the rotating connection 20 and the rotating connection 20 and the head body 30.

[0053] In some embodiments, the rotating connector 20 is annular and is sleeved on the head body 30 ; the bracket 10 has two connecting arms 15 , the two connecting arms 15 are spaced apart, and the rotating connector 20 is rotatably connected between the two connecting arms 15 .

[0054] Specifically, the first axis 330 and the second axis 340 pass through the annular rotating connection member 20 perpendicularly to each other and intersect on the axis of the rotating connection member 20 .

[0055] It can be understood that the first wiring groove 11 is at least partially located on the connecting arm 15. The rotating connecting member 20 is sleeved on the cover 33 of the head body 30, and the diameter of the rotating connecting member 20 is greater than the diameter of the cover 33.

[0056] In this way, the head body 30 is rotatably connected to the rotating connection member 20 and can rotate within a certain range in the rotating connection member 20. Specifically, the head body 30 can swing left and right in the rotating connection member 20, and can swing up and down on the two connecting arms 15 following the rotating connection member 20.

[0057] Specifically, the first rotating shaft structure 23 is provided on the rotating connecting member 20, and specifically there are two of them, and they are respectively provided on opposite sides of the rotating connecting member 20. The connecting arm 15 of the bracket 10 has a rotating hole 151 that matches with the first rotating shaft structure 23. The second rotating shaft structure 24 can also be provided on the rotating connecting member 20, and the cover 33 of the head body 30 has an upper hole 331 that matches with the second rotating shaft structure 24. In addition, the rotating connecting member 20 also has a lower matching hole 27, and the cover 33 also has a lower hole 333 corresponding to the lower matching hole 27. The head assembly 100 also includes a latch 60, which is inserted into the lower matching hole 333, and the latch 60 has a buckle 61 that matches with the hole edge of the lower matching hole 27, so as to realize the rotating connection between the rotating connecting member 20 and the head body 30.

[0058] Please also read Figures 6 to 8 In some embodiments, the bracket 10 includes a first inner shell 13 and a first outer shell 14, the first inner shell 13 forms the first wiring groove 11, and the first outer shell 14 is covered on the first inner shell 13; and / or the rotating connecting member 20 includes a second inner shell 25 and a second outer shell 26, the second inner shell 25 forms the second wiring groove 21, and the second outer shell 26 is covered on the second inner shell 25.

[0059] It can be understood that the first outer shell 14 is covered on the first inner shell 13 to cover the first wiring trough 11 and enclose the first inner shell 13. Similarly, the second outer shell 26 is covered on the second inner shell 25 to cover the second wiring trough 21 and enclose the second inner shell 25.

[0060] In this way, the first outer shell 14 and the second outer shell 26 can not only protect the line 40 located in the first wiring groove 11 and the second wiring groove 21, but also constrain its wiring, improve its stability, and reduce the impact of the swing of the head body 30 on the line 40.

[0061] Please also read Figures 9 to 11 In some embodiments, the head body 30 has a first end 310 and a second end 320 in the front-to-back direction, and the first end 310 is an air outlet end. The head assembly 100 further includes a rotating member 50, which is transmission-connected to the second end 320 on the head body 30 and is used to drive the second end 320 to rotate eccentrically.

[0062] The rotating member 50 is used to drive the second end 320 to rotate eccentrically, and the eccentric rotation may or may not have an eccentric shaft. In addition, the head assembly 100 may also include a driving member, which is used to drive the rotating member 50 to drive the second end 320 to rotate eccentrically.

[0063] It can be understood that when the second end 320 of the head body 30 rotates, the first end 310 can also be driven accordingly, that is, it can shake its head accordingly according to the eccentric rotation of the second end 320 .

[0064] In this way, the head body 30 rotates to connect the bracket 10, and can rotate in at least two directions that intersect the front and rear directions. The rotating member 50 can drive the other end of the head body 30 opposite to the air outlet end to rotate eccentrically, and accordingly, the air outlet end of the head body 30 is driven and swings accordingly. In this way, during the corresponding swinging process of the air outlet end of the head body 30, the direction of the air outlet end is constantly changing, so that the air is supplied to different areas, achieving the effect of expanding the air supply range. In addition, the head assembly 100 only needs to be configured with a single driving member to drive the rotating member 50 to drive the head body 30 to shake its head in two directions, that is, to shake its head up and down and left and right synchronously.

[0065] In some embodiments, the first axis 330 and the second axis 340 are configured to intersect.

[0066] It can be understood that the rotation of the head body 30 around the first axis 330 and the rotation around the second axis 340 can be combined into a conical swing centered at the intersection of the first axis 330 and the second axis 340 .

[0067] Specifically, the first axis 330 and the second axis 340 are both located between the first end 310 and the second end 320 , and the center of gravity of the nose body 30 is located at the intersection of the first axis 330 and the second axis 340 .

[0068] In this way, the first end 310 and the second end 320 of the head body 30 can perform stable conical swing. Only by controlling the conical swing angle of the second end 320, the angle of the first end 310 as the air outlet end can be accurately controlled, that is, its air supply range can be controlled.

[0069] Furthermore, the rotating member 50 is rotatably connected to the bracket 10 around the third axis 350 , and has a transmission structure 53 spaced apart from the third axis 350 , and drives the second end 320 to eccentrically rotate around the third axis 350 through the transmission structure 53 .

[0070] It can be understood that when the rotating member 50 rotates around the third axis 350, the transmission structure 53 thereon is equivalent to revolving around the third axis 350, and accordingly, the second end 320 driven thereby also rotates eccentrically around the third axis 350. The third axis 350 may intersect the first axis 330 and the second axis 340 at one point.

[0071] The rotating member 50 has a central axis structure 51 arranged along the third axis 350, and the bracket 10 has a limit rotation hole 16 that cooperates with the central axis structure 51. The rotating member 50 is rotatably inserted into the limit rotation hole 16 through the central axis structure 51, and can be fixed with a screw 55 to achieve rotation relative to the bracket 10.

[0072] In this way, the rotating member 50 can naturally drive the second end 320 to rotate eccentrically around the third axis 350 through its transmission structure 53 during the process of rotating around the third axis 350 .

[0073] Specifically, bearings may be provided between the central axis structure 51 of the rotating member 50 and the limiting rotating hole 16 to reduce the rotation resistance of the rotating member 50 .

[0074] In some embodiments, the head body 30 also includes a transmission shaft 36, which is connected to the main motor 31 in a transmission manner and is connected to the rotating member 50 at the second end 320 of the head body 30 through the transmission structure 53 in a rotationally fixed manner around its own axis.

[0075] It can be understood that the main motor 31 is a driving member, which can be but is not limited to a dual-axis motor with two output shafts, which are respectively located at the front and rear ends thereof, the front output shaft is connected to the fan blade 32, and the rear output shaft is connected to the transmission shaft 36, and the rotating member 50 is located at the rear of the head body 30. The transmission shaft 36 passes through the rear cover 34 to prevent rotation and connect to the rotating member 50.

[0076] The transmission shaft 36 can rotate under the drive of the main motor 31 , and the transmission shaft 36 is arranged along the front-to-back direction of the head body 30 , and can be coaxially arranged with the cover shell 33 .

[0077] Since the transmission shaft 36 and the rotating member 50 are connected to each other by the transmission structure 53, they cannot rotate around their own axis when rotating, and can only realize their own rotation by driving the rotating member 50 to rotate around the third axis 350, thereby generating a reaction force. The transmission shaft 36 drives the second end 320 of the head body 30 to rotate eccentrically around the third axis 350, that is, the second end 320 performs a conical swing with one point as the vertex, and the first end 310 performs a conical follower with this point as the vertex.

[0078] In this way, the main motor 31 can not only drive the fan blades 32 to rotate to deliver air, but also drive the rotating member 50 through the transmission shaft 36, thereby generating a reaction force to drive the head body 30 to swing in a conical shape to expand the air.

[0079] Furthermore, the transmission structure 53 is a D-shaped hole, and one end of the transmission shaft 36 is anti-rotationally engaged with the D-shaped hole in the direction of rotation around its own axis.

[0080] In this way, the rotating member 50 can be anti-rotationally engaged with the transmission shaft 36 through the D-shape. It can be understood that in some other embodiments, the transmission structure 53 can also be other structures, such as a triangular hole, a square hole, etc., as long as it can achieve anti-rotation engagement with the transmission shaft 36 in the direction of rotation around the axis of the transmission shaft 36, and no specific limitation is made here.

[0081] In some embodiments, the head body 30 further includes a reduction gearbox 37 , and the transmission shaft 36 is transmission-connected to the main motor 31 via the reduction gearbox 37 .

[0082] It can be understood that the reduction box 37 can reduce the speed of the output of the main motor 31 so that the speed of the transmission shaft 36 finally driven by the main motor 31 meets the requirements.

[0083] In this way, the reduction box 37 can reduce the output rotation of the main motor 31 so that the speed at which the main motor 31 drives the head body 30 to perform conical swing is within an appropriate range.

[0084] In some embodiments, the head assembly 100 further includes an operating member 371 , and the operating member 371 is operable to control the transmission connection and disconnection between the transmission shaft 36 and the main motor 31 .

[0085] Specifically, the operating member 371 may be, but is not limited to, a pressing member, and can cause the reducer to start transmission by being pressed.

[0086] In this way, the user can control whether the head body 30 moves in a conical shape through the operating member 371 as needed.

[0087] In addition, the main motor 31 may also have a knob 311 for controlling its own start, stop and gear position.

[0088] In some other embodiments, the reduction box 37 has a control driver, and the control driver is controlled to control the transmission shaft 36 to connect and disconnect the transmission with the main motor 31 to achieve remote control or automatic control.

[0089] In some embodiments, the angle between the transmission shaft 36 and the third axis 350 is configured to be adjustable.

[0090] It can be understood that the change in the angle between the transmission shaft 36 and the third axis 350 will correspondingly change the swing angle of the nose body 30 .

[0091] Specifically, the rotating plate can be provided with a transmission structure 53 at different intervals from the third axis 350 , and the angle between the transmission shaft 36 and the third axis 350 can be achieved by changing the transmission structure 53 matched with the transmission shaft 36 .

[0092] The head assembly 100 can switch between the air expansion and circulation functions by adjusting the angle between the transmission shaft 36 and the third axis 350. When performing the air expansion function, the cone angle of the head body 30 when performing the conical shaking of the head is less than the set value, and when performing the air expansion function of the circulation function, the cone angle of the head body 30 when performing the conical shaking of the head is not less than the set value, wherein the set value may be but is not limited to 30°.

[0093] In this way, the user can change the swing angle of the head body 30 by adjusting the angle between the transmission shaft 36 and the third axis 350 as needed.

[0094] In another embodiment, the head assembly 100 may further include an air expansion oscillating motor, which is connected to the rotating member 5030, that is, the driving member is the air expansion oscillating motor. In this way, the head assembly 100 can omit the reduction gearbox 37, and the air expansion oscillating motor can drive the air expansion oscillating motor alone, and the air expansion oscillating motor is incorporated into the control circuit to realize the independent control of the air expansion oscillating function.

[0095] In some embodiments, the rotating member 50 is an arc-shaped plate, and the center of the arc-shaped plate is the intersection of the third axis 350 and the axis of the transmission shaft 36 .

[0096] Specifically, the first axis 330 , the second axis 340 , the third axis 350 , and the axis of the transmission shaft 36 may intersect at one point.

[0097] In this way, during the rotation of the transmission shaft 36 around the third axis 350 , the angle between the transmission shaft 36 and the rotating member 50 may not change, and the rotation is more stable.

[0098] In the above-mentioned head assembly 100, the main motor 31 of the head assembly 100 is decelerated by the reduction box 37, and the torque is transmitted through the coaxial transmission shaft 36. The transmission shaft 36 is connected to the rotating member 50 which is not concentric and at a certain angle. When the torque of the main motor 31 is transmitted to the rotating member 50 through the transmission shaft 36, because the rotation axis of the rotating member 50 is at a certain angle with the axis of the head, the rotation of the rotating member 50 drives the head body 30 to rotate eccentrically around the axis of the rotating member 50, thereby realizing the function of conical air expansion or circulating air. On this basis, the line 40 can be routed along the first wiring groove 11 and the second wiring groove 21, and finally reach the head body 30, and the line 40 is constrained and protected by the first inner shell 13, the first outer shell 14, the second inner shell 25 and the second outer shell 26. When the head body 30 shakes its head, the line 40 generally only has a small coaxial twist at the first wire hole 12 and the second wire hole 22, and will not be pulled or bent at a large angle. In this way, while the head assembly 100 shakes its head, the line 40 passing through it will not be pulled significantly or bent at a large angle, and the risk of the wire core breaking or the wire body wearing is effectively reduced.

[0099] The present application also provides a fan 200, including the head assembly 100. It can be understood that, in order to achieve its normal function, the fan 200 also includes a body assembly 201, the head assembly 100 is connected to the body assembly 201 through the bracket 10, and the body assembly 201 may have a third wire hole 202 for the line 40 to pass through.

[0100] In some embodiments, the head assembly 100 is connected to the body assembly 201 by rotating around the height direction of the fan 200 through the bracket 10 .

[0101] Specifically, the fan 200 may further include a head shaking motor, which is connected to the bracket 10 and is used to drive the bracket 10 to rotate around the height direction of the fan 200.

[0102] In this way, the head assembly 100 can be rotated as a whole through the bracket 10, which helps to further improve the air supply range of the fan 200.

[0103] The fan 200 has a line 40 introduced through the third wire hole 202 at the back of the body assembly 201, and passes through the first wire groove 11, the first wire hole 12, the second wire groove 21 and the second wire hole 22 in the bracket 10, and is connected to the main motor 31 in the head body 30. When the head is turned on, no matter the head swings up and down or left and right, the entire line 40 will not be pulled back and forth or bent back and forth, and only the wire hole will be slightly twisted. The relative movement of the internal wire core is small, which helps to extend the service life of the line 40.

[0104] The technical features of the above-described embodiments may be arbitrarily combined. To make the description concise, not all possible combinations of the technical features in the above-described embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0105] The above-described embodiments only express several implementation methods of the present application, and the descriptions thereof are relatively specific and detailed, but they cannot be construed as limiting the scope of the patent application. It should be pointed out that, for a person of ordinary skill in the art, several variations and improvements can be made without departing from the concept of the present application, and these all belong to the protection scope of the present application. Therefore, the protection scope of the patent application shall be subject to the attached claims.
