For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0032] Below is the attached figure Figures 1 to 7 The technical solution of the utility model is further illustrated by specific implementation methods.

[0033] like Figure 1-7 As shown, a multi-angle shaking fan includes a supporting assembly 1, a left and right shaking assembly 2, a support 3, a fan head 4 and an up and down shaking assembly 5;

[0034] The left and right shaking assembly 2 is installed at the top of the supporting assembly 1, and the bottom end of the support 3 is installed at the driving end of the left and right shaking assembly 2. The left and right shaking assembly 2 is used to drive the support 3 to rotate left and right relative to the supporting assembly 1;

[0035] Two support arms 31 extend upward from both sides of the support 3, the fan head 4 is installed between the two support arms 31, and the up and down shaking assembly 5 is arranged in the fan head 4, and the up and down shaking assembly 5 is used to drive the fan head 4 to swing up and down relative to the two support arms 31.

[0036] In this solution, through the mutual cooperation of the support component 1, the left and right shaking component 2, and the support 3, the fan head 4 can make a large-angle left and right shaking movement relative to the support component 1; the up and down shaking component 5 of the fan head 4 is used to control the fan head 4 to make up and down shaking movements, thereby realizing up and down and left and right shaking of the head to supply air over a large area.

[0037] like Figure 1 As shown, the support assembly 1 includes a base 11 and a column 12 , and the column 12 is fixedly installed on the top of the base 11 .

[0038] like Figure 2-3 As shown, the left and right shaking assembly 2 includes a connecting bracket 21, a rotating bracket 22 and a first motor 23;

[0039] The connecting bracket 21 is fixedly installed on the top of the column 12, and the rotating bracket 22 is fixedly installed on the bottom end of the support 3. The rotating bracket 22 is arranged at the top of the connecting bracket 21, and the top of the connecting bracket 21 has a protrusion 211. The rotating bracket 22 is rotatably sleeved on the outside of the protrusion 211. The bottom end of the support 3 is provided with a limiting groove 33, and the top of the first motor 23 is engaged in the limiting groove 33. The bottom end of the first motor 23 is in contact with the top of the rotating bracket 22, and the protrusion 211 is coaxially connected to the output shaft of the first motor 23.

[0040] Specifically, when the fan head 4 needs to rotate left and right, the first motor 23 is started, and the output shaft of the first motor 23 is coaxially connected to the raised portion 211 of the connecting bracket 21. Since the connecting bracket 21 is fixedly connected to the column 12, the column 12 is fixed to the top of the base 11, and the base 11 is placed on the ground and cannot rotate. At this time, the first motor 23 in the limiting groove 33 of the support 3 rotates itself, thereby driving the support 3 to rotate. The support 3 simultaneously drives the rotating bracket 22 to rotate around the raised portion 211, thereby driving the fan head 4 to rotate left and right.

[0041] like Figure 2-3 As shown, the side wall of the rotating bracket 22 is symmetrically provided with a first sliding groove 221 , and the two sides of the protruding portion 211 are symmetrically provided with a first sliding block 212 , and the two first sliding blocks 212 are slidably installed in the corresponding first sliding groove 221 .

[0042] Specifically, by cooperating with the first slider 221 and the first slide groove 221, the rotation angle of the rotating bracket 22 can be limited to prevent the fan from being damaged due to excessive rotation, and the rotating bracket 22 can be prevented from being separated from the protrusion 211, so that the connection between the rotating bracket 22 and the protrusion 211 is more stable.

[0043] like Figure 2 As shown, a receiving cavity 32 is provided at the bottom end of the support 3 , the limiting groove 33 is located in the receiving cavity 32 , and the left and right shaking head components 2 are arranged in the receiving cavity 32 .

[0044] Specifically, by providing the accommodation cavity 32 to accommodate the left and right shaking components 2, the overall appearance of the device can be made more beautiful.

[0045] like Figure 4-7As shown, the fan head 4 includes a casing 41, and mesh covers are provided at the front and rear ends of the casing 41. A fixing plate 42 is provided inside the casing 41, and the fixing plate 42 is installed on one of the mesh covers. A second motor 43 is provided in the middle of the fixing plate 42, and the output shaft of the second motor 43 is coaxially connected with the fan blade 44. Shaft covers 45 are fixedly installed on both sides of the fixing plate 42, and a shaft hole 451 is opened on the side of the shaft cover 45 facing the fixing plate 42. A first shaft sleeve 46 is rotatably installed in the shaft hole 451, and one end of the first shaft sleeve 46 is coaxially connected with a second shaft sleeve 47, and the end of the second shaft sleeve 47 away from the first shaft sleeve 46 passes through the shaft cover 45 and is fixedly connected to the support arm 31.

[0046] Specifically, when the fan head 4 swings up and down, the shaft covers 45 on both sides of the fixing plate 42 rotate around the first shaft sleeve 46, and the mesh cover connected to the fixing plate 42 drives the casing to rotate. When blowing air, the second motor 43 is started to drive the fan blades 44 to rotate for blowing air.

[0047] like Figure 7 As shown, the outer diameter of the first sleeve 46 is greater than the outer diameter of the second sleeve 47 .

[0048] Specifically, the outer diameter of the first sleeve 46 is greater than the outer diameter of the second sleeve 47. When the fixed plate 42 is installed between the two second sleeves 47 through the two shaft covers 45, the fixed plate 42 can be prevented from moving axially along the second sleeves 47, so that the fixed plate 42 is stably installed between the two second sleeves 47 and can rotate relative to the second sleeves 47.

[0049] like Figure 6-7 As shown, the outer side wall of the first sleeve 46 is provided with a second sliding block 461 , the inner side wall of the shaft hole 451 is provided with a second sliding groove 452 , and the second sliding block 461 is slidably installed in the second sliding groove 452 .

[0050] Specifically, by using the second sliding block 461 in conjunction with the second sliding groove 452 , the rotation angle of the fan head 4 can be limited to prevent the fan from being damaged due to excessive rotation.

[0051] like Figure 7 As shown, a positioning block 471 is provided at one end of the second sleeve 47 away from the first sleeve 46 , a positioning groove is provided on the side wall of the support arm 31 , and the positioning block 471 is engaged with the positioning groove.

[0052] Specifically, by cooperating between the positioning block 471 and the positioning groove, the second sleeve 47 and the support arm 31 can be quickly and conveniently connected together, and then the second sleeve 47 and the support arm 31 can be connected together with the help of fasteners to facilitate assembly.

[0053] like Figure 5 As shown, the up and down shaking assembly 5 includes an inner gear ring 51 and a third motor 52. The inner gear ring 51 is coaxially fixedly installed on one end of one of the first sleeves 46 away from the second sleeve 47. The inner ring gear 51 is internally meshed and connected with a planetary gear 53. The planetary gear 53 is coaxially installed on the output shaft of the third motor 52. The third motor 52 is fixedly installed on the side wall of the fixed plate 42.

[0054] Specifically, when the fan head 4 needs to swing up and down, the third motor 52 is started. Since the second sleeve 47 at one end of the first sleeve 46 is fixedly connected to the support arm 31, when the third motor 52 drives the planetary gear 53 to rotate, the planetary gear 53 meshing with the inner ring gear 53 will drive the third motor 52 to rotate around the axis of the inner ring gear 51, and the third motor 52 will drive the shaft cover 45 connected to the fixing plate 42 to rotate around the first sleeve 46, so that the mesh cover connected to the fixing plate 42 drives the casing 41 to rotate, thereby causing the fan head 4 to swing up and down.

[0055] The technical principle of the present invention is described above in combination with specific embodiments. These descriptions are only for explaining the principle of the present invention and cannot be interpreted as limiting the protection scope of the present invention in any way. Based on the explanations here, technicians in this field can think of other specific implementation methods of the present invention without creative work, and these methods will fall within the protection scope of the present invention.
