[0104] like Figure 3 As shown, in the swing mechanism 2, the swing motor support 201 is connected to the swing motor 202. The swing motor 202 is a micro motor with a single-direction rotating shaft, and the motor 202 has a reducer, and its structure and principle are the same as those of the swing motor of the heater, which is a mature technology at present and will not be described in detail here.

[0105] likeFigure 3-1 and Figure 3-11 As shown (please view in combination), the compound rotary device 203 can be implemented in two schemes. One is the belt type, and the other is the gear type. Although their structures are different, they achieve the same goal by different means and can ultimately achieve coaxial bidirectional power output. Here, the belt type compound rotary device will be specifically described as an example.

[0106] As Figure 3-1 shown, the belt type compound rotary device includes a driving pulley 207, a swinging pulley 208, and a rubber belt 209.

[0107] As Figure 3-1 and Figure 3-2 shown (please view in combination), the driving pulley 207 is connected to the rotating shaft of the swinging motor 202.

The diameter of this component is equal to that of the bearing wheel disc 213. The two clutch collar rings are fixedly sleeved on the external threaded connecting pipe 204 and are respectively located on the upper and lower sides of the swing pulley 208. Similar to the bearing wheel disc 213, the clutch collar ring 205 is also provided with a friction surface 215 on one side. When sleeved, the friction surface 215 of the clutch collar ring 205 should correspond to the friction surface 215 of the bearing wheel disc 213, and the friction surface 215 of one side clutch collar ring 205 is in close contact with the friction surface 215 of the bearing wheel disc 213 to form a friction pair. The friction surface 215 of the other side clutch collar ring 205 is close to but not in contact with the friction surface 215 of the bearing wheel disc 213, so that there is no friction force between the two.

[0112] As Figure 3-6 and Figure 3-7 shown in Figure 3-6 and Figure 3-7 (please view in combination), the regulator 206 includes a regulator support 218, a regulator fork piece 219 and a regulator knob 220.

This device is composed of a regulator connecting plate 225 and two regulator forks 226. The regulator connecting plate 225 is provided with a threaded hole 227 at its center and positioning rod sliding holes 228 on both sides thereof. The regulator forks 226 and the positioning rod sliding holes 228 are symmetrically arranged with the threaded hole 227 as the symmetry center, and the two positioning rod sliding holes 228 are respectively located outside the two regulator forks 226. The distance between the two regulator forks 226 is slightly larger than the diameter of the internal threaded connecting pipe 214.

[0115] As Figure 3-9 and Figure 3-10As shown (please view in combination), the regulator knob 220 includes four parts: a screw 229, a convex ring 230, a knob cap 231, and a fixing screw 232. It is characterized in that one end of the screw 229 is provided with a thread 233, which matches the size of the threaded hole 227. The other end is provided with a connecting groove 234. The convex ring 230 is fixedly arranged on the screw 229 and is close to the connecting groove 234. The knob cap 231 is sleeved on the screw 229 and is clamped with the connecting groove 234.

[0117] Among them, as Figure 4-1 shown, the green hose 301 can be made of plastic or cloth, and its function is to maintain the integrity of the flexible simulation flower stem 3. The elastic member 302 arranged in the green hose 301 can be a metal spring, or a metal hose can be used to replace it when there is no metal spring. Its function is to fill the empty part of the green hose 301 and maintain the natural bending shape of the simulation flower stem when adjusting the pitch of the fan head for air supply.

[0118] As Figure 4-2 shown, among them, the flower-shaped fan head support tube 303 is provided with a connecting small screw hole 415, an air intake motor power cord penetration hole 611, and a connecting member 306. And, the connecting member 306 is provided with an air intake motor power cord outlet hole 308 at its center and a connecting screw 309 on its outer periphery.

[0119] As Figure 4-1 shown, the connecting small screw hole 415 and the small screw 407 are used for connecting the flower-shaped fan head support tube 303 and the rotating large screw 406. The connecting screw 309 is used for connecting the connecting member 306, the connecting plate 610, and the connecting ring 609. When connecting, the connecting member 306, the connecting plate 610, and the connecting ring 609 are connected in sequence from back to front.

[0120] As Figure 4-1 、 Figure 3 and Figure 7-2As shown (please view in combination), in the installed state, the power cord inlet 611 is used for the power cord of the air intake motor to pass through. After the power cord of the air intake motor passes through the air intake motor power cord inlet 611, it extends along the pipeline of the flower-shaped fan head support pipe 303 to the tail of the air intake motor, and then passes through the power cord inlet hole 618 at the center of the connecting plate 610, and finally is connected to the air intake motor 602.

[0121] As Figure 5 shown, the tubular support frame 4 includes a support pipe 401 and a support connection assembly 402 sleeved on the upper end of the support pipe 401.

[0122] As Figure 1-2 shown, in the installed state, the upper end of the tubular support frame 4 is hinged to the flexible simulation flower stem 3, and the lower end is vertically inserted into the flower pot-shaped base 1.

[0123] As Figure 3 and Figure 5 shown (please view in combination), among them, the lower section of the tubular support frame 4 inserted into the flower pot-shaped base 1 is provided with an external thread connecting pipe 204 of the swing mechanism; above the flower pot-shaped base 1 and in the middle section of the support pipe 401, there is a common power cord inlet and outlet hole 403 for devices such as the external power cord 7, the air intake motor 602, and the swing motor 202, and connecting screws 404 for connecting the control component box 5 are provided at the upper and lower ends of the common power cord inlet and outlet hole 403.

In addition, a rough concave-convex structure 409 is provided on the outside of one ear flap, and a support pipe sleeving hole 410 is provided at its bottom.

[0126] As Figure 5-3 、 Figure 5-2 and Figure 5-1 shown (please view in combination), among them, the screw head of the large rotating screw 406 is also provided with a rough concave-convex structure 409 on the side close to the screw rod. The concave-convex structure 409 of the screw head matches the size and shape of the concave-convex structure 409 on the connection support 405, and a small threaded hole 411 matching the size of the small fixing screw 407 is provided on the screw rod part of the large rotating screw 406.

[0127] As Figure 3As shown in the figure, the screwing direction of the screw rod thread of the large rotating screw 406 needs to be consistent with the gravity direction of the flower-shaped fan head 6. In this way, it can be ensured that the large rotating screw 406 will not become loose under the action of the gravity of the flower-shaped fan head 6, but instead the large rotating screw 406 will be pressed tighter and tighter.

[0128] As Figure 2-1 shown, the flower-pot-shaped base 1 includes an enamel-like outer shell 101, a bottom plate 102, a fixing plate 103, and a simulated soil plate 104.

The simulated soil plate 104 is located in the upper inner part of the flower-pot-shaped base 1, and its planar shape is matched to the planar shape of the flower-pot-shaped base 1. When the planar shape of the flower-pot-shaped base 1 is circular, the simulated soil plate 104 is a single-body structure with a circular plane. A tubular support frame sleeve hole 414 is provided at the center of this structure, and a simulated flower stem insertion hole 307 is provided at its side part. The simulated soil plate with a circular plane is fixedly sleeved on the tubular support frame 4. When the tubular support frame 4 rotates, the circular simulated soil plate 104 can rotate together with the tubular support frame 4. When the planar shape of the flower-pot-shaped base 1 is square or regular polygon, the simulated soil plate 104 is a two-body structure composed of a square or regular polygon hole outer plate and a circular inner plate. Among them, the hole outer plate of the two-body structure is fixed on the enamel-like outer shell 101. A tubular support frame sleeve hole 414 is provided at the center of the circular inner plate, and a simulated flower stem insertion hole 307 is provided at its side part.

[0132] As Figure 6 shown, the control component box 5 is the control and adjustment center of the swing motor 202 and the air intake motor 602 in the present invention. There are control switch buttons 501 for the swing motor 202 and the air intake motor 602 above it, and a common power cord hole 502 for the external power cord 7, the swing motor 202 and the air intake motor 602 on the side. At the same time, connection screw holes 503 for connecting the control component box 5 and the tubular support frame 4 are provided at the upper and lower ends of the common power cord hole 502. The positions of the common power cord hole 502 and the connection screw hole 503 correspond to and match the common power cord hole 403 and the connection screw 404 on the tubular support frame. In order to improve the ornamental and simulation effects of the present invention, the control component box 5 is designed as a flower protection sign. In this embodiment, the control component box 5 can adopt the control device of an existing double-motor household fan. Among them, as Figure 9 shown, the external power cord 7 is a current mature technology, and its structure and usage method are the same as those of the power cord of a rice cooker sold on the market, so it will not be elaborated here.

[0133] In this embodiment, the power cord routing is as follows:

[0134] As Figure 1-1 、 Figure 2-1 、 Figure 3 、 Figure 4-1 、 Figure 5 、 Figure 6 、 Figure 7-2 and Figure 11-1As shown (please refer to it in combination), after the external power cord 7 is connected to the cored plug 701, it enters the support tube 401 through the external power cord through hole 702 on the side of the bearing support 412, then goes up from the lower end of the support tube 401 and passes out through the common power cord inlet and outlet hole 403, and then passes through the common power cord hole 502 on the side of the control component box 5 and penetrates into the control component box 5. Then, the two groups of power cords for the air intake motor 602 and the swing motor 202 are separated by the parallel method. After these two groups of power cords are respectively connected to their respective control component switches, they pass out through the common power cord hole 502 of the control component box 5 and the common power cord hole 403 of the support tube 401, and then they travel in separate directions. The power cord of the air intake motor 602 travels upward, and the power cord of the swing motor 202 travels downward; the power cord of the air intake motor 602 travels upward along the pipeline of the support tube 401 and passes out through the support tube sleeve hole 410, then penetrates into the air intake motor power cord inlet hole 611 on the flower-shaped fan head support tube 303, and then extends along the pipeline of the flower-shaped fan head support tube 303 to the tail of the air intake motor 602, and finally penetrates into the casing through the power cord inlet hole 618 on the connecting plate 610 and is finally connected to the air intake motor 602; the power cord of the swing motor 202 travels downward along the pipeline of the support tube 401 and passes out through the swing motor power cord through hole 236 on the bearing support 412, then is parallel to the bottom plate 102 to the swing mechanism support 201, and then is connected to the swing motor 202.

[0135] As Figure 11-1 shown, in this embodiment, the working principle and process of the fan to realize counterclockwise air supply are as follows:

[0136] Turn on the power switch of the swing motor 202, and the rotating shaft of the swing motor 202 starts to rotate in the clockwise direction; when the rotating shaft of the swing motor 202 rotates in the clockwise direction, it drives the driving part pulley 207 to rotate in the clockwise direction; when the driving part pulley 207 rotates in the clockwise direction, it drives two rubber belts 209 to rotate in different directions. Among them, the rubber belt connected in a "0" shape rotates in the clockwise direction, and the rubber belt connected in an "8" shape rotates in a crossed direction; since in the swing part pulley, rolling bearings are provided on both the upper and lower bearing wheel discs 213, when the rubber belt 209 connected in a "0" shape rotates in the clockwise direction, it drives the bearing wheel disc 213 on the swing part pulley to rotate in the clockwise direction. At the same time, when the rubber belt 209 connected in an "8" shape rotates in a crossed direction, it finally drives the bearing wheel disc 213 on the swing part pulley to rotate in the counterclockwise direction; since the bearing wheel disc 213 driven by the rubber belt 209 connected in an "8" shape is in close contact with the clutch collar 205, when the rubber belt 209 connected in an "8" shape drives the bearing wheel disc 213 to rotate in the counterclockwise direction, the bearing wheel disc 213 rotating in the counterclockwise direction will also drive the clutch collar 205 to rotate in the counterclockwise direction; since the bearing wheel disc 213 driven by the rubber belt 209 connected in a "0" shape is adjacent to the clutch collar 205, when the rubber belt 209 connected in a "0" shape drives the bearing wheel disc 213 to rotate in the clockwise direction, due to the lack of friction, the bearing wheel disc 213 rotating in the clockwise direction will not drive the clutch collar 205 to rotate, and it will only rotate idly in the clockwise direction. (When the bearing wheel disc 213 rotates idly, it has no practical significance and will not be described here); since the clutch collar 205 is fixedly connected to the tubular support frame 4, when the clutch collar 205 rotates in the counterclockwise direction, it will drive the tubular support frame 4 to rotate in the counterclockwise direction; when the tubular support frame 4 rotates in the counterclockwise direction, it simultaneously drives the externally threaded connecting pipe 204 and the flower-shaped fan head 6 to rotate in the counterclockwise direction; when the flower-shaped fan head 6 rotates in the counterclockwise direction, the function of the counterclockwise shaking and air supply of the present invention is realized.

[0137] As Figure 11-2 shown, the working principle and process of the fan to realize the clockwise air supply in this embodiment are as follows:

[0138] Immediately following the above description, when the fan realizes the function of blowing air in the counterclockwise direction, the external thread connecting pipe 204 rotates counterclockwise. When the external thread connecting pipe 204 rotates counterclockwise, it will drive the internal thread connecting pipe 214 sleeved on the external thread connecting pipe 204 to rotate counterclockwise; when the internal thread connecting pipe 214 rotates counterclockwise, it drives the contact rod 217 connected to the internal thread connecting pipe 214 to rotate counterclockwise. When the contact rod 217 rotates to the regulator fork 226, it stops rotating due to the resistance of the regulator fork 226; when the contact rod 217 stops rotating, the internal thread connecting pipe 214 connected to the contact rod 217 also stops rotating; since the frictional force between the bearing wheel disc 213 and the closely contacting clutch collar 205 has not been released, and the flower-shaped fan head 6 has a certain inertia when rotating counterclockwise, so, within a short period of time after the internal thread connecting pipe 214 stops rotating, the tubular support frame 4 and the external thread connecting pipe 204 of its lower part will still continue to rotate counterclockwise; when taking the external thread connecting pipe 204 that keeps rotating counterclockwise as a stationary reference object, the internal thread connecting pipe 214 that stops rotating due to resistance rotates clockwise; when the internal thread connecting pipe 214 rotates clockwise, under the action of the spiral force, the internal thread connecting pipe 214 will move downward. When the internal thread connecting pipe 214 moves downward, it will drive the two bearing wheel discs 213 hinged to it to move downward at the same time; when the bearing wheel discs 213 connected by the rubber belt 209 in an "8" shape move downward, they will separate from the closely contacting clutch collar 205. In this way, the bearing wheel disc 213 that originally drove the clutch collar 205 to rotate counterclockwise will rotate idly; on the contrary, when the bearing wheel discs 213 connected by the rubber belt 209 in a "0" shape move downward, they will come into close contact with the adjacent clutch collar 205. In this way, the bearing wheel disc 213 that originally rotated idly clockwise will drive the clutch collar 205 to rotate clockwise; when the clutch collar 205 rotates clockwise, since the clutch collar 205 is fixedly connected to the tubular support frame 4, it will drive the tubular support frame 4 to rotate clockwise; when the tubular support frame 4 rotates clockwise, it will drive the external thread connecting pipe 204 and the flower-shaped fan head 6 to rotate clockwise at the same time; when the flower-shaped fan head 6 rotates clockwise, the function of blowing air in the clockwise direction of the present invention is realized.

[0139] According to the above principle, when the present invention needs to re-realize the function of blowing air in the counterclockwise direction, the above-mentioned steps are repeated.

[0140] As Figure 11-1 shown, the working principle and process of the swing mechanism for reducing the air supply coverage area in this embodiment are as follows:

[0141] Rotate the knob cap 231 counterclockwise, driving the screw rod 229 to rotate counterclockwise; when the screw rod 229 rotates counterclockwise, under the action of the spiral force, the distance between the regulator fork head 226 and the internally threaded connecting pipe 214 is pushed closer. When the distance between the regulator fork head 226 and the internally threaded connecting pipe 214 is pushed closer, the rotation arc of the contact rod 217 is reduced. This is because when the contact rod 217 rotates to the regulator fork head 226, it will encounter the resistance of the regulator fork head 226 and stop rotating; when the rotation arc of the contact rod 217 is reduced, the rotation arc of the internally threaded connecting pipe 214 is also reduced; when the rotation arc of the internally threaded connecting pipe 214 is reduced, the rotation arc of the externally threaded connecting pipe 204 will also be reduced accordingly; when the rotation arc of the externally threaded connecting pipe 204 is reduced, the rotation arc of the flower-shaped fan head 6 is also reduced. When the rotation arc of the flower-shaped fan head 6 is reduced, the air supply coverage area is also reduced accordingly.

[0142] As Figure 11-2 shown, the working principle and process of the swing mechanism for enlarging the air supply coverage area in this embodiment are as follows:

[0143] Conversely, when we want to enlarge the air supply angle of the flower-shaped fan head, we rotate the knob cap 231 clockwise. Specifically:

[0144] Rotate the knob cap 231 clockwise, driving the screw rod 229 to rotate clockwise; when the screw rod 229 rotates clockwise, under the action of the spiral force, the distance between the regulator fork head 226 and the internally threaded connecting pipe 214 is pulled farther; when the distance between the regulator fork head 226 and the internally threaded connecting pipe 214 is pulled farther, the rotation arc of the contact rod 217 is enlarged. This is because when the contact rod 217 rotates to the regulator fork head 226, it will also encounter the resistance of the regulator fork head 226 and stop rotating; when the rotation arc of the contact rod 217 is enlarged, the rotation arc of the internally threaded connecting pipe 214 is also enlarged; 11. When the rotation arc of the internally threaded connecting pipe 214 is enlarged, the rotation arc of the externally threaded connecting pipe 204 will also be enlarged accordingly; when the rotation arc of the externally threaded connecting pipe 204 is enlarged, the air supply angle of the flower-shaped fan head 6 is also enlarged accordingly.

[0145] In addition, the fan in this embodiment can adjust the pitching air supply angle in the following way:

[0146] Loosen the nut of the rotating large screw 406, adjust the flower-shaped fan head 6 up or down to the required angle, and then tighten the nut of the rotating large screw 406.

[0147] It should be noted that all the features disclosed in this specification, or all the steps in the disclosed methods or processes, except for mutually exclusive features and / or steps, can be combined in any way.
