[0001] The present application relates to the technical field of fans, and in particular to a multi-directional shaking mechanism and a circulating fan. Background Art

[0002] In order to speed up the air circulation efficiency in the room, most circulation fans are designed with automatic shaking functions in the up and down and left and right directions. However, in the related art, in order to achieve the above shaking function, two synchronous motors are mostly used to control the shaking operation in the two directions respectively, which makes the internal structure of the whole machine complicated and the cost is high. Summary of the invention

[0003] Based on this, it is necessary to provide a multi-directional shaking head mechanism and a circulating fan to address the problem that the circulating fan uses two motors to control the shaking head in two directions respectively.

[0004] To achieve the above objectives, the technical solutions adopted in this application are as follows:

[0005] In a first aspect, an embodiment of the present application provides a multi-directional shaking head mechanism, comprising:

[0006] A head assembly, comprising a housing, a driving member installed in the housing, and a first transmission shaft connected to one end of the driving member;

[0007] A support assembly, comprising two supporting plates arranged opposite to each other and a rotating plate rotatably arranged between the two supporting plates;

[0008] Among them, one end of the two support plates away from the rotating plate is rotatably connected to the opposite sides of the head assembly respectively, and one end of the first transmission shaft away from the driving member is locked with the non-axial part of the rotating plate, so that under the drive of the driving member, the first transmission shaft drives the head assembly and the rotating plate to rotate about the axis of the rotating plate.

[0009] Through the above design, the head assembly can be driven by only one driving member to achieve multiple direction shaking of up and down, left and right.

[0010] In one of the embodiments of the first aspect, the head assembly further includes a connecting ring, which is sleeved on the outer side of the cover shell, and the two support plates are rotatably connected to opposite ends of the outer side of the connecting ring respectively.

[0011] Through the above design, the cover shell can rotate left and right relative to the connecting ring, and the cover shell and the connecting ring can rotate up and down relative to the support plate. During the operation of the head assembly, the cover shell shakes up and down and left and right respectively to increase the wind sweeping range of the head assembly.

[0012] In one of the embodiments of the first aspect, a first rotating shaft is provided at an inner end of the connecting ring, and a first connecting hole is correspondingly provided in the cover shell. The first rotating shaft passes through the first connecting hole, and a first clamping groove is provided at one end thereof located in the cover shell. The head assembly also includes a first clamping spring, which is installed in the first clamping groove.

[0013] Through the above design, the first retaining spring limits the first rotating shaft to the first connecting hole, thereby achieving stable assembly of the connecting shaft and the cover shell.

[0014] In one of the embodiments of the first aspect, the head assembly also includes a latch, a second connecting hole is opened on the side of the cover shell away from the first rotating axis, a third connecting hole is opened on the side of the connecting ring away from the first rotating axis, and the latch is sequentially inserted into the second connecting hole and the third connecting hole.

[0015] Through the above design, the lower ends of the cover shell and the connecting ring are limited by the rotation of the latch, so that the cover shell and the connecting ring can be assembled in steps, thereby improving the efficiency of assembly and disassembly.

[0016] In one of the embodiments of the first aspect, a plurality of flange blocks are circumferentially provided at one end of the latch pin located in the connecting ring, and each of the flange blocks is passed through the third connecting hole and snap-fitted with the connecting ring.

[0017] Through the above design, after the latch enters the third connecting hole, the flange block presses against the end of the third connecting hole of the connecting ring to limit the movement of the latch in the vertical direction, thereby ensuring the stable connection between the cover shell and the connecting ring.

[0018] In one embodiment of the first aspect, a second rotating shaft is provided at two opposite ends of the outer side of the connecting ring, and a fourth connecting hole is provided at one end of the two support plates connected to the connecting ring. The end of each second rotating shaft away from the connecting ring is passed through a corresponding fourth connecting hole and provided with a second slot, and the head assembly also includes a second retaining spring, which is installed in the second retaining groove.

[0019] Through the above design, the second rotating shaft can rotate up and down along the axis of the second rotating shaft relative to the supporting plate, thereby driving the cover shell assembled with the connecting ring to shake up and down.

[0020] In one of the embodiments of the first aspect, the head assembly further includes a gearbox, which is mounted on a side of the driving member where the first transmission shaft is provided, and is respectively connected to the driving member and the first transmission shaft for transmission.

[0021] Through the above design, the rotation speed of the first transmission shaft is adjusted, thereby limiting the shaking rate of the head assembly, reducing the wear of the first transmission shaft, and improving the service life of the entire machine.

[0022] In one embodiment of the first aspect, the head assembly further includes a fan blade and a second transmission shaft, one end of the second transmission shaft is connected to an end of the driving member facing away from the first transmission shaft, and the other end is connected to the fan blade.

[0023] Through the above design, the air supply of the fan blades and the shaking and sweeping of the head assembly in multiple directions can be achieved only through the single driving component. The overall structure is streamlined and efficient, and the production cost of the circulation fan is effectively reduced.

[0024] In one embodiment of the first aspect, one end of the first transmission shaft connected to the rotating plate is a non-circular end, the rotating plate is correspondingly provided with a non-circular hole, and the non-circular end is plug-fitted with the non-circular hole.

[0025] Through the above design, during the rotation of the first transmission shaft, the first transmission shaft cannot rotate independently relative to the rotating plate, thereby driving the rotating plate to rotate along its axis, and further driving the head assembly to perform conical rotational motion.

[0026] In a second aspect, an embodiment of the present application further provides a circulating fan, comprising the multi-directional shaking head mechanism described in any of the above embodiments.

[0027] Through the above design, the air supply operation of the fan blade and the shaking operation of the head assembly can be realized by only a single motor, the overall structure is simplified, and the production cost is reduced.

[0028] Compared with the related art, the beneficial effect of the present application is as follows: the present application provides a multi-directional shaking mechanism and a circulating fan, which can realize the multi-directional shaking and rotation of the circulating fan. The multi-directional shaking mechanism includes a head assembly and a bracket assembly. Among them, the head assembly includes a cover shell and a driving member and a first transmission shaft installed in the cover shell, and the bracket assembly includes a support plate rotatably connected to the two opposite sides of the cover shell and a rotating plate rotatably arranged between the two supporting plates, and the first transmission shaft is engaged with the non-axial part of the rotating plate. In this way, during the operation of the driving member, the driving member drives the first transmission shaft to rotate, and the end of the second transmission shaft connected to the rotating plate cannot rotate relative to the rotating plate, thereby forming a cam-like structure, driving the rotating plate to rotate together, and then causing the head assembly to rotate conically with the axis of the rotating plate. In this way, under the drive of a motor, the head assembly can shake its head in multiple directions to simplify the overall structure and reduce production costs. BRIEF DESCRIPTION OF THE DRAWINGS

[0047] See also Figure 1 As shown, the embodiment of the present application provides a multi-directional shaking mechanism, which can achieve multi-directional shaking of the working part through a single driving member 112. For ease of understanding, the multi-directional shaking mechanism provided in the embodiment of the present application can be illustrated by using a circulating fan 100 as an example of an application scenario, and accordingly, the working part is the head assembly 110 of the circulating fan 100.

[0048] Continue reading Figure 2 and Figure 3 As shown, specifically, the multi-directional shaking mechanism includes a head assembly 110 and a bracket assembly 120. The head assembly 110 includes a housing 111, a driving member 112 and a first transmission shaft 113, wherein the driving member 112 is installed in the housing 111, and the first transmission shaft 113 is coaxially arranged with the driving member 112 and connected to one end of the driving member 112, so as to rotate under the drive of the driving member 112.

[0049] The bracket assembly 120 includes two support plates 121 and a rotating plate 122. The two support plates 121 are symmetrically arranged and are rotatably connected to two opposite sides of the cover shell 111 respectively, so that the cover shell 111 can at least rotate up and down relative to the support plates 121, thereby realizing the up and down shaking operation of the head assembly 110.

[0050] Preferably, the cover shell 111 and the support plate 121 can be universally connected, such as by a ball head to achieve a rotational connection between the cover shell 111 and the support plate 121. In this case, the cover shell 111 can rotate in any direction relative to the support plate 121, thereby achieving multi-directional shaking and sweeping of the head assembly 110 up, down, left, and right.

[0051] Continue reading Figure 4 As shown, the two support plates 121 can be designed in an integrated manner, and the rotating plate 122 is a circular plate, the axis of which is fixed to the connection of the two support plates 121 by bolts, so that the rotating plate 122 can rotate along its own axis relative to the connection of the two support plates 121. At the same time, the end of the first transmission shaft 113 away from the driving member 112 is locked with the non-axial part of the rotating plate 122, so that the first transmission shaft 113 cannot rotate independently relative to the rotating plate 122. During the operation of the driving member 112, the first transmission shaft 113 drives the rotating plate 122 to rotate along the axis of the rotating plate 122.

[0052] In summary, the operating principle of the multi-directional shaking mechanism provided by the present application is as follows: the driving member 112 is a rotating motor, which drives the first rotating shaft 1141 to rotate during operation, and the first rotating shaft 1141 cannot rotate freely relative to the rotating plate 122, thereby driving the rotating plate 122 to rotate together. Since the driving member 112 is fixed in the housing 111, and the support plate 121 is rotatably connected to the housing 111, during the rotation of the first rotating shaft 1141, the housing 111 and the driving member 112 as a whole follow the first rotating shaft 1141 to perform a conical rotation along the axis of the rotating plate 122, thereby realizing a 360° shaking and sweeping of the head assembly 110, and the head assembly 110 can shake in multiple directions up and down, left and right only through a motor drive.

[0053] It should be noted that, in the embodiment of the present application, “up and down” refers to the direction of gravity, that is, the vertical direction of the circulation fan 100, “left and right” refers to the horizontal wind sweeping direction of the circulation fan 100, which is perpendicular to the direction of gravity, and “front and back” refers to the wind outlet side direction and the leeward side direction of the circulation fan 100, respectively.

[0054] Continue reading Figure 5 and Figure 6 As shown, in some embodiments, one end of the first transmission shaft 113 connected to the rotating plate 122 is a non-circular end 1131 , and the rotating plate 122 is correspondingly provided with a non-circular hole 1221 , and the non-circular end 1131 is plugged into and matched with the non-circular hole 1221 .

[0055] Exemplarily, the non-circular shape in this embodiment may include various regular or irregular polygons, such as triangles, quadrilaterals, sectors, etc. In this specific embodiment, one end of the first transmission shaft 113 connected to the rotating plate 122 is a D-shaped shaft with a semicircular arc structure, and the rotating plate 122 is correspondingly provided with a D-shaped hole with a semicircular arc structure. In this way, through the cooperation between the D-shaped shaft and the D-shaped hole, during the rotation of the first transmission shaft 113, the first transmission shaft 113 cannot rotate relative to the rotating plate 122 alone, thereby driving the rotating plate 122 to rotate along its axis, and then driving the head assembly 110 to perform a conical rotation motion.

[0056] Continue reading Figure 7 and Figure 8 As shown, in some embodiments, the head assembly 110 further includes a connecting ring 114 , which is sleeved on the outer side of the cover shell 111 , and the two support plates 121 are rotatably connected to opposite ends of the outer side of the connecting ring 114 .

[0057] Specifically, the two support plates 121 are rotatably connected to the left and right ends of the connecting ring 114, and the cover 111 is sleeved on the inner side of the connecting ring 114, so that the cover 111 and the connecting ring 114 can rotate up and down relative to the support plates 121. At the same time, the connecting ring 114 is rotatably connected to the upper and lower sides of the cover 111, so that the cover 111 can rotate left and right relative to the connecting ring 114. In this way, during the operation of the head assembly 110, the cover 111 shakes its head up and down and left and right respectively, thereby increasing the sweeping range of the head assembly 110.

[0058] Furthermore, a first rotating shaft 1141 is provided at one end of the inner side of the connecting ring 114, and a first connecting hole is correspondingly provided at the housing 111. The first rotating shaft 1141 is passed through the first connecting hole, and a first clamping groove is provided at one end of the first rotating shaft 1141 located inside the housing 111. The head assembly 110 further includes a first clamping spring installed in the first clamping groove.

[0059] Specifically, the first rotating shaft 1141 is fixed to the inner upper end of the connecting ring 114. During the assembly process, the first rotating shaft 1141 is inserted into the first connecting hole, so that the housing 111 can rotate relative to the axis of the first rotating shaft 1141. In addition, a first clamping groove is provided at one end of the first rotating shaft 1141 inserted into the first connecting hole, and the first rotating shaft 1141 is confined to the first connecting hole by a first clamping spring, so that the assembly of the connecting shaft and the housing 111 is stable.

[0060] Furthermore, the head assembly 110 also includes a latch 115, a second connecting hole is opened on the side of the cover 111 away from the first rotating axis 1141, a third connecting hole is opened on the side of the connecting ring 114 away from the first rotating axis 1141, and the latch 115 is sequentially inserted into the second connecting hole and the third connecting hole.

[0061] Specifically, the second connection hole is formed at the lower side of the cover 111, and the third connection hole is formed at the inner lower end of the connection ring 114 and is aligned with the second connection hole, so that the second connection hole and the third connection hole are sequentially penetrated by the latch 115, and the latch 115 is coaxially arranged with the first rotation axis 1141. In this way, the cover 111 can shake left and right along the common axis of the latch 115 and the first rotation axis 1141, and the assembly of the cover 111 and the connection ring 114 is stabilized by the latch 115 and the first rotation axis 1141. At the same time, the lower ends of the cover 111 and the connection ring 114 are limited by the rotation of the latch 115, so that the step-by-step assembly of the cover 111 and the connection ring 114 is realized, thereby improving the efficiency of assembly and disassembly.

[0062] Continue reading Fig. 9 As shown, further, a plurality of flange blocks are circumferentially provided at one end of the latch pin 115 located in the connecting ring 114 , and each flange block is passed through the third connecting hole and is snap-fitted with the connecting ring 114 .

[0063] Exemplarily, the number of flange blocks can be two, three, four, five, etc., which can be reasonably set according to design requirements or the size of the latch 115, and is not specifically limited here. The flange block protrudes compared to the main body of the latch 115, so that after the latch 115 enters the third connection hole, the flange block is pressed against the port of the third connection hole of the connecting ring 114, limiting the movement of the latch 115 in the vertical direction, and ensuring the stability of the connection between the cover 111 and the connecting ring 114. At the same time, there is a certain distance between two adjacent flange blocks, so that during the insertion process of the latch 115, each flange block can be retracted in the axial direction, so that the latch 115 can be quickly removed from the second connection hole and the third connection hole, and open when entering the connecting ring 114, so that the latch 115 is assembled and fixed with the connecting ring 114.

[0064] Preferably, the side of the flange block is provided with an inclined surface, so that the ends of the second connection hole and the third connection hole are pressed against the inclined surface of the flange block during the insertion of the latch 115. In this way, when the latch 115 is inserted into the connecting ring 114 along the axial direction, the flange block gathers in the axial direction under the guidance of the inclined surface, which facilitates the assembly of the latch 115.

[0065] In some embodiments, a second rotating shaft 1142 is provided at two opposite ends of the outer side of the connecting ring 114, and a fourth connecting hole is provided at one end of the two supporting plates 121 connected to the connecting ring 114. One end of each second rotating shaft 1142 away from the connecting ring 114 is passed through a corresponding fourth connecting hole and provided with a second clamping groove, and the head assembly 110 further includes a second clamping spring installed in the second clamping groove.

[0066] Specifically, the two second rotating shafts 1142 are respectively arranged on the left and right sides of the connecting ring 114, and the two supporting plates 121 are also relatively distributed left and right. In this way, through the assembly of the second rotating shaft 1142 and the supporting plate 121, the second rotating shaft 1142 can rotate up and down along the axis of the second rotating shaft 1142 relative to the supporting plate 121, thereby driving the cover 111 assembled with the connecting ring 114 to shake up and down, thereby realizing the multi-directional shaking and sweeping of the head assembly 110 up and down and left and right.

[0067] In some embodiments, the head assembly 110 further includes a gearbox 118 , which is mounted on a side of the driving member 112 where the first transmission shaft 113 is provided, and is respectively connected to the driving member 112 and the first transmission shaft 113 .

[0068] Specifically, a gear set structure is provided in the gearbox 118, which is respectively connected to the driving member 112 and the first transmission shaft 113, so as to adjust the rotation speed of the first transmission shaft 113, thereby limiting the shaking speed of the head assembly 110, reducing the wear of the first transmission shaft 113, and improving the service life of the whole machine.

[0069] In some embodiments, the head assembly 110 further includes a fan blade 117 and a second transmission shaft 116 , one end of the second transmission shaft 116 is connected to an end of the driving member 112 facing away from the first transmission shaft 113 , and the other end is connected to the fan blade 117 .

[0070] Specifically, the second transmission shaft 116 is connected to the driving member 112, and the driving member 112 drives the fan blades 117 to rotate, thereby supplying air to the user. In this way, the fan blades 117 can supply air and the head assembly 110 can shake its head in multiple directions to sweep air only through the single driving member 112. The overall structure is streamlined and efficient, and the production cost of the circulation fan 100 is effectively reduced.

[0071] In other embodiments, only the first transmission shaft 113 may be provided, and the first transmission shaft 113 passes through both ends of the driving member 112, so that both ends of the first transmission shaft 113 are respectively connected to the rotating plate 122 and the fan blade 117. In this way, the first transmission rod is driven to rotate by the driving member 112, so as to realize the rotation of the fan blade 117 and the shaking operation of the head assembly 110.

[0072] An embodiment of the present application further provides a circulation fan 100, comprising the multi-directional shaking head mechanism described in any of the above embodiments.

[0073] This embodiment has the multi-directional shaking head mechanism of any of the above embodiments, and therefore has all the beneficial effects of the multi-directional shaking head mechanism of any of the above embodiments, which will not be elaborated here.

[0074] 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.

[0075] 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.
