[0047] Referring to Figure 1 As shown, the embodiment of the present application provides a multi-directional head shaking mechanism, which can realize multi-directional head shaking of the working part through a single driving member 112. For ease of understanding, the multi-directional head shaking mechanism provided by the embodiment of the present application can be exemplified by a circulating fan 100, and accordingly, the working part is a head assembly 110 of the circulating fan 100.

[0048] Continuing to refer to Figure 2 and Figure 3 As shown, specifically, the multi-directional head shaking mechanism includes the head assembly 110 and a support 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 to rotate the work under the driving of the driving member 112.

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

[0050] Preferably, the cover 111 is connected with the support plate 121 in a universal manner, such as through a ball joint, so that the cover 111 can rotate relative to the support plate 121 in any direction, thereby achieving multi-directional head swinging of the head assembly 110.

[0051] With reference to 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 member, the axis of which is fixed to the connection between the two support plates 121 by a bolt, so that the rotating plate 122 can rotate along its own axis relative to the connection between the two support plates 121. Meanwhile, the end of the first transmission shaft 113 away from the driving member 112 is rotationally connected with the non-axis 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 operation principle of the multi-directional head swinging mechanism 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. Since the driving member 112 is fixed in the cover 111, and the support plate 121 is rotationally connected with the cover 111, during the rotation of the first rotating shaft 1141, the cover 111 and the driving member 112 as a whole follow the first rotating shaft 1141 to perform conical rotation along the axis of the rotating plate 122, thereby achieving 360° head swinging of the head assembly 110. Only one motor is needed to drive the head assembly 110 to swing in multiple directions.

[0053] It should be noted that “up and down” in the embodiments of the present application refers to the direction of gravity, i.e., the vertical direction of the circulating fan 100, “left and right” refers to the horizontal sweeping direction of the circulating fan 100, which is perpendicular to the direction of gravity, and “front and back” respectively refer to the air outlet surface direction and the air inlet surface direction of the circulating fan 100.

[0054] With reference to Figure 5 and Figure 6 As shown, in some embodiments, the end of the first transmission shaft 113 connected with the rotating plate 122 is a non-circular end 1131, and the rotating plate 122 correspondingly has a non-circular hole 1221, and the non-circular end 1131 is insertedly connected with the non-circular hole 1221.

[0055] Exemplarily, the non-circular shape in the embodiment can include various regular or irregular polygons, such as triangle, quadrilateral, sector, etc. In the specific embodiment, the end of the first transmission shaft 113 connected with 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 of the D-shaped shaft and the D-shaped hole, the first transmission shaft 113 cannot rotate alone relative to the rotating plate 122 in the rotation process of the first transmission shaft 113, so as to drive the rotating plate 122 to rotate along its axis, and further drive the head assembly 110 to perform a conical rotary motion.

[0056] Referring back to FIGS. 1, 2 and 3, Figure 7 and Figure 8 In some embodiments, the head assembly 110 further includes a connecting ring 114, which is sleeved on the outside of the shell 111, and the two support plates 121 are respectively rotatably connected to the opposite ends of the outside of the connecting ring 114.

[0057] Specifically, the two support plates 121 are respectively rotatably connected to the left and right ends of the connecting ring 114, and the shell 111 is sleeved on the inside of the connecting ring 114, so that the shell 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 shell 111, so that the shell 111 can rotate left and right relative to the connecting ring 114. In this way, during the operation of the head assembly 110, the shell 111 performs up and down and left and right shaking, respectively, to improve the sweeping range of the head assembly 110.

[0058] Further, the inside end of the connecting ring 114 is provided with a first rotating shaft 1141, and the shell 111 is correspondingly provided with a first connecting hole. The first rotating shaft 1141 is inserted into the first connecting hole, and the end of the first rotating shaft 1141 inside the shell 111 is provided with a first clamping groove, and 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 inside upper end of the connecting ring 114, and during assembly, the first rotating shaft 1141 is inserted into the first connecting hole, so that the shell 111 can rotate relative to the axis of the first rotating shaft 1141. In addition, the end of the first rotating shaft 1141 inserted into the first connecting hole is provided with a first clamping groove, and the first rotating shaft 1141 is limited in the first connecting hole by the first clamping spring, so as to realize the stable assembly of the connecting shaft and the shell 111.

[0060] Still further, the head assembly 110 further includes a latch 115, the side of the shell 111 away from the first rotating shaft 1141 is provided with a second connecting hole, the side of the connecting ring 114 away from the first rotating shaft 1141 is provided with a third connecting hole, and the latch 115 is sequentially inserted into the second connecting hole and the third connecting hole.

[0061] Specifically, the second connecting hole is arranged at the lower part of the cover shell 111, and the third connecting hole is arranged at the inner lower end of the connecting ring 114 and is aligned with the second connecting hole, so that the plug pin 115 is sequentially inserted through the second connecting hole and the third connecting hole, and the plug pin 115 is coaxially arranged with the first rotating shaft 1141. In this way, the cover shell 111 can swing left and right along the common axis of the plug pin 115 and the first rotating shaft 1141, and the cover shell 111 is stably assembled with the connecting ring 114 through the plug pin 115 and the first rotating shaft 1141. At the same time, the lower end of the cover shell 111 and the connecting ring 114 is limited by rotating the plug pin 115, so that the cover shell 111 and the connecting ring 114 are assembled step by step, and the disassembly efficiency is improved.

[0062] Continuing to refer to Figure 9 Further, one end of the plug pin 115 located in the connecting ring 114 is provided with a plurality of flange blocks in the circumferential direction, and each flange block is arranged in the third connecting hole and is in clamping cooperation with the connecting ring 114.

[0063] For example, 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 plug pin 115, and is not limited here. The flange blocks protrude from the main body of the plug pin 115, so that when the plug pin 115 enters the third connecting hole, the flange blocks abut against the port of the third connecting hole of the connecting ring 114, limiting the movement of the plug pin 115 in the vertical direction, and ensuring the stable connection of the cover shell 111 and the connecting ring 114. At the same time, there is a certain spacing between the adjacent two flange blocks, so that during the insertion process of the plug pin 115, the flange blocks can be gathered towards the axis direction, so that the plug pin 115 can be quickly disassembled into the second connecting hole and the third connecting hole, and expanded when entering the connecting ring 114, so that the plug pin 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 during the insertion process of the plug pin 115, the port of the second connecting hole and the third connecting hole abuts against the inclined surface of the flange block. In this way, when the plug pin 115 is inserted into the connecting ring 114 along the axis direction, the flange blocks are gathered towards the axis direction under the guidance of the inclined surface, facilitating the assembly of the plug pin 115.

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

[0066] Specifically, two second rotating shafts 1142 are arranged on the left and right sides of the connecting ring 114 respectively, and the two support plates 121 are also arranged oppositely. In this way, through the assembly of the second rotating shaft 1142 and the support plate 121, the second rotating shaft 1142 can rotate up and down along the axis of the second rotating shaft 1142 relative to the support plate 121, thereby driving the shell 111 assembled with the connecting ring 114 to swing up and down, so as to realize the multi-directional swing of the head assembly 110 up and down, left and right.

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

[0068] Specifically, the gearbox 118 is provided with a gear set structure, which is in transmission connection with the driving member 112 and the first transmission shaft 113 respectively, so as to adjust the rotating speed of the first transmission shaft 113, thereby limiting the swing rate of the head assembly 110, slowing down the wear of the first transmission shaft 113, and prolonging the service life of the whole machine.

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

[0070] Specifically, through the connection of the second transmission shaft 116 and the driving member 112, the driving member 112 drives the fan blade 117 to rotate, thereby supplying air to the user. In this way, only a single driving member 112 can realize the air supply of the fan blade 117 and the multi-directional swing of the head assembly 110, the overall structure is simple, the efficiency is high, and the production cost of the circulating fan 100 is effectively reduced.

[0071] In other embodiments, only the first transmission shaft 113 can be provided, and the first transmission shaft 113 penetrates through both ends of the driving member 112, so that the two ends of the first transmission shaft 113 are connected with the rotating plate 122 and the fan blade 117 respectively. In this way, the rotation of the fan blade 117 and the swing operation of the head assembly 110 are realized by driving the first transmission rod to rotate through the driving member 112.

[0072] The embodiments of the present application also provide a circulating fan 100 comprising the multi-directional swing mechanism in any of the above-mentioned embodiments.

[0073] The embodiment has the multi-directional swing mechanism in any of the above-mentioned embodiments, and therefore has all the beneficial effects of the multi-directional swing mechanism in any of the above-mentioned embodiments, which will not be repeated here.

[0074] Any combination of the technical features in the above-described embodiments can be made, and for the sake of brevity, not all possible combinations are described, however, it is to be understood that the application embraces all such possible combinations.

[0075] The above-described embodiments only express several implementation manners of the present application, and the description is relatively specific and detailed, but it should not be understood as a limitation on the patent scope of the application. It should be pointed out that for ordinary skilled persons in the art, some modifications 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 patent protection scope of the present application should be subject to the appended claims.
