They cannot deliver air at different heights at the same time, and lack a large-angle air outlet. This leads to problems such as a small air supply range, small angle, and small air volume. It cannot achieve the purpose of quickly cooling down a large area of ​​the human body by blowing air, and requires a long wait, which makes the user experience poor. Utility Model Content

[0055] Reference Figure 5 , Figure 6 The wide-angle air supply assembly 3 includes a motor 31 installed and fixedly connected in the first receiving groove 127 on the first connecting seat 123. A driving gear 310 is fixedly connected to the output shaft of the motor 31. When the motor 31 is started, the driving gear 310 is driven to rotate.

A driven gear 38 is fixedly connected to the other end of the first rotating shaft 32. The driven gear 38 is meshed with the driving gear 310. The rotation of the driving gear 310 drives the driven gear 38 to rotate, thereby driving the first rotating shaft 32 to rotate. A first bearing 39 is fixedly connected in the first receiving groove 127. The first rotating shaft 32 is passed through the first bearing 39. The first bearing 39 supports the first rotating shaft 32, so that the first rotating shaft 32 is stably installed on the first connecting seat 123.

[0056] The first rotating seat 33 is installed on the end of the first rotating shaft 32 passing through the first connecting hole 125. The first rotating seat 33 is penetrated by a first through hole 335. The first through hole 335 is a special-shaped hole. The first rotating shaft 32 is plugged and matched with the first through hole 335, so that the first rotating seat 33 can be driven to rotate when the first rotating shaft 32 rotates. Among them, the first lap ring 321 is fixedly connected to the first rotating shaft 32. The first lap ring 321 is arranged on the lower side of the first rotating seat 33. The first rotating seat 33 is lapped on the first lap ring 321, so that the first rotating seat 33 can be installed more stably after being connected to the first rotating shaft 32.

[0057] The end of the first rotating shaft 32 passes through the upper side of the first rotating seat 33, and a first knob 34 is fixedly mounted and fixedly connected to the end of the first rotating shaft 32.

[0058] The first rotating seat 33 includes a first mounting plate 331 and a first connecting plate 332 fixedly connected to the first mounting plate 331. The first through hole 335 is provided through the first mounting plate 331 and the first connecting plate 332.

[0059] Reference Figure 7 , Figure 8 A first slot 333 is provided on the first mounting plate 331, and a first plug block 334 is inserted into the first slot 333. The first plug block 334 is plugged into the first slot 333.

The first oblique rod 35 and the first shaft seat 36 are connected to the first rotating seat 33 through the first plug block 334. The first oblique rod 35 is installed on the radius of the first rotating seat 33 and is bent inward at a certain bending angle. The first plug rod 361 is rotatably connected to the upper side of the first shaft seat 36, and the first fan blade 37 is sleeved on the linear plug rod 212.

The first convex ridge 362 is arranged on the first plug rod 361. The first convex ridge 362 is inserted into the first fan blade 37 along with the first plug rod 361. The fan blows and drives the first fan blade 37 to rotate. When the first fan blade 37 rotates, it drives the first plug rod 361 to rotate on the first shaft seat 36. Since the first oblique rod 35 is arranged obliquely, the first fan blade 37 is inclined relative to the straight fan blade 22 .

[0061] When the fan is delivering air, the wind blown by the fan drives the first fan blade 37 to rotate on the first shaft seat 36, and then the motor 31 is started, driving the driving gear 310 to rotate, the driving gear 310 rotates to drive the driven gear 38 to rotate, the driven gear 38 rotates to drive the first rotating shaft 32 to rotate, the first rotating shaft 32 rotates to drive the first rotating seat 33 to rotate, the first rotating seat 33 rotates to drive the first shaft seat 36 to rotate, so that the first fan blade 37 rotates while revolving along the center of the first rotating seat 33, constantly changing the direction of the first fan blade 37, and then changing the air supply angle of the first fan blade 37.

[0062] In order to further increase the air supply angle, a synchronous air supply component 4 can be installed on the second connecting seat 124. The synchronous air supply component 4 is connected to the wide-angle air supply component 3 through the synchronous component 5. When the wide-angle air supply component 3 is started, the motor 31 transfers power to the synchronous air supply component 4 through the synchronous component 5, driving the synchronous air supply component 4 to start, thereby further increasing the air supply area.

[0063] Reference Fig. 9 , Fig.10The synchronous air supply assembly 4 includes a sleeve 41 fixedly connected to the second receiving groove 128, two second bearings 42 are installed in the sleeve 41, and a second rotating shaft 43 is penetrated on the two second bearings 42, one end of the second rotating shaft 43 passes through the second connecting hole 126, and a second lap ring 431 is fixedly connected to the second rotating shaft 43.

A second plug rod 461 is rotatably connected to the upper side of the second shaft seat 46, and a second fan blade 47 is sleeved on the linear plug rod 212. The second plug rod 461 is inserted into the central area of ​​the second fan blade 47 and plugged together with the second fan blade 47, so that the second fan blade 47 is connected to the second shaft seat 46. A second convex ridge 462 is arranged on the second plug rod 461. The second convex ridge 462 is inserted into the second fan blade 47 along with the second plug rod 461. The fan blows and drives the second fan blade 47 to rotate. When the second fan blade 47 rotates, it drives the second plug rod 461 to rotate on the second shaft seat 46. Since the second oblique rod 45 is arranged obliquely, the second fan blade 47 is inclined relative to the straight fan blade 22 .

[0066] The end of the second rotating shaft 43 passes through the upper side of the second rotating seat 44, and a second knob 48 is fixedly mounted and fixedly connected to the end of the second rotating shaft 43. The second knob 48 and the second lap ring 431 clamp the second rotating seat 44, so that the second rotating seat 44 is installed more tightly on the second rotating shaft 43, preventing the second rotating seat 44 from loosening during rotation, and further improving the stability of the installation of the second rotating seat 44.

[0067] The synchronous assembly 5 includes a synchronous belt 51, which is tightly mounted on the first connecting plate 332 and the second connecting plate 442. When the first rotating seat 33 rotates, the synchronous belt 51 is driven to rotate by the friction force. When the synchronous belt 51 rotates, the second rotating seat 44 is driven to rotate by the friction force, so that the second rotating seat 44 and the first rotating seat 33 rotate synchronously.

[0068] Reference Figure 8 , Fig.10 The first connection disk 332 is provided with a first groove 336, which is provided along the circumference of the first connection disk 332, and the second connection disk 442 is provided with a second groove 446 which is arranged along the circumference of the second connection disk 442.

[0069] In addition, the belt drive in the synchronous assembly 5 can be changed to a gear drive.

[0070] The implementation principle of a wide-angle air supply fan in the embodiment of the present application is as follows: when the fan is started, the fan drives the linear fan blade 22, the first fan blade 37, and the second fan blade 47 to rotate along their own axis to discharge air; the motor 31 rotates, driving the first rotating seat 33 to rotate, and when the first rotating seat 33 rotates, it drives the second rotating seat 44 to rotate, and when the first rotating seat 33 and the second rotating seat 44 rotate, the first fan blade 37 rotates while revolving along the center of the first rotating seat 33, and the second fan blade 47 rotates while revolving along the center of the second rotating seat 44, constantly changing the directions of the first fan blade 37 and the second fan blade 47, and then changing the air supply angle of the first fan blade 37 and the second fan blade 47, thereby increasing the air outlet range of the fan, and spreading the air supply range of the fan outward, achieving a wider-angle air supply experience for the multi-head fan.
