[0048] The following are specific embodiments of the present invention and the accompanying drawings to further describe the technical solutions of the present invention, but the present invention is not limited to these embodiments.

[0049] like Figures 1 to 18 As shown, a shell 1 is provided with a driving member 4, a total air inlet end 100 and a total air outlet end 101 are provided in the shell 1, and a blade assembly is provided on the total air outlet end 101; an air guide assembly 2 is provided on the shell 1 and connected to the driving member 4, and the air guide assembly 2 can control the switch of the total air inlet end 100 and the total air outlet end 101; a swing assembly 3 is provided on the shell 1 and connected to the blade assembly, and the swing assembly 3 can control the blade assembly to swing; the driving member 4 has a first state, a second state and a third state, and the driving member 4 can switch between the first state, the second state and the third state; when the electric air outlet structure is in the first state, the driving member 4 drives the swing assembly 3 and the air guide assembly 2 to move synchronously; when the electric air outlet structure is in the second state, the driving member 4 drives the air guide assembly 2 to move alone; when the electric air outlet structure is in the third state, the driving member 4 drives the swing assembly 3 to move alone.

[0050] Specifically, in the first state, the driving member 4 is connected to the swing assembly 3 and the air guide assembly 2. At this time, the driving member 4 can control the air guide assembly 2 and the swing assembly 3 to move simultaneously, so that the swing assembly 3 can adjust the swing direction of the blade assembly, and also enable the air guide assembly 2 to control the switch of the total air outlet end 101.

[0051] In the second state, the swing component 3 is stationary, and the driving member 4 drives the air guide component 2 to move alone, and the air guide component 2 can control the switch of the main air inlet end 100.

[0052] The third state is that the air guide assembly 2 is stationary, and the driving member 4 alone drives the swing assembly 3 to move, and the swing assembly 3 can adjust the swing direction of the blade assembly.

[0053] like Figures 2 to 7 As shown, the swing assembly 3 has a connecting frame 300, a blade crank 301 and a positioning frame 308. The positioning frame 308 is connected to the shell 1. The blade crank 301 is inserted into the positioning frame 308 and connected to the blade crank 301. The connecting frame 300 is connected to the blade assembly. The driving member 4 can drive the connecting frame 300 to perform axial movement through the blade crank 301, so that the blade assembly swings.

[0054] The positioning frame 308 is connected to the shell 1 through bolts, and the blade crank 301 is rotated to insert the positioning frame 308. The positioning frame 308 positions the blade crank 301 to prevent the blade crank 301 from falling off when rotating. When the driving member 4 rotates, it drives the blade crank 301 to rotate. The blade crank 301 is movably connected to the connecting frame 300, so that the connecting frame 300 moves axially, and drives the blade assembly to swing during the movement, thereby controlling the air outlet angle of the total air outlet end 101.

[0055] like Figures 1 to 4 As shown, a driving wheel 400 is installed on the driving end of the driving member 4. The driving wheel 400 is rotatably arranged on the housing 1 and is movably connected to the blade crank 301.

[0056] A side cover 106 is provided on the side of the shell 1, and the driving member 4 is installed on the side cover 106. The side cover 106 plays a fixing role for the driving member 4. The driving member 4 is a motor. The driving wheel 400 has two connecting ends. The connecting end on one side of the driving wheel 400 is connected to the driving end of the driving member 4, and the connecting end on the other side of the driving wheel 400 is rotatably connected to the shell 1. After the driving member 4 is started, the driving wheel 400 will also rotate synchronously to drive the blade crank 301 to rotate.

[0057] like Figures 2 to 7 As shown, the driving wheel 400 is provided with a first connecting rod 402 and a second connecting rod 403, one end of the blade crank 301 is provided with a track groove 302, the first connecting rod 402 and the second connecting rod 403 are slidingly connected to the track groove 302, and the other end of the blade crank 301 is provided with a rotating part 303, and a toggle block 304 is spirally distributed on the rotating part 303, and a spiral hole 305 is opened on the connecting frame 300, and the toggle block 304 is clamped with the spiral hole 305.

[0058] A first connecting rod 402 and a second connecting rod 403 are provided on the driving wheel 400. The track groove 302 has a left slot and a right slot. The first connecting rod 402 can enter the track groove 302 from the right slot, and the second connecting rod 403 can enter the track groove 302 from the left slot. The first connecting rod 402 moves in the track groove 302 and abuts against the slot surface of the track groove 302, which can realize the first state of the electric air outlet structure. The first connecting rod 402 moves in the track groove 302, but the first connecting rod 402 does not abut against the track groove, and detaches outward along the right slot of the track groove, which can realize the second state of the electric air outlet structure. The second connecting rod 403 moves in the track groove 302 and abuts against the slot surface of the track groove 302, which can realize the third state of the electric air outlet structure.

[0059] The first connecting rod 402 and the second connecting rod 403 can both move on the track groove 302 and abut against the groove surface of the track groove 302, thereby pushing the blade crank 301 to rotate, so that the rotating part 303 provided at the other end of the blade crank 301 also rotates. During the rotation of the rotating part 303, the toggle block 304 cooperates with the spiral hole 305, and then the connecting frame 300 moves axially, that is, controls the swing of the blade assembly. It is worth mentioning that a group of positioning grooves 309 are provided on the side of the positioning frame 308 facing the shell 1, and sliders 310 are provided on both sides of the connecting frame 300, and the sliders 310 are connected to the positioning grooves 309. When the connecting frame 300 moves axially, the sliders 310 cooperate with the positioning grooves 309 to ensure that the axial movement of the connecting frame 300 is smoother, thereby better driving the blade assembly to swing.

[0060] like Figures 1 to 7 As shown, the total air outlet end 101 has a first air duct 102 and a second air duct 103, the first air duct 102 and the second air duct 103 are connected to the total air inlet end 100, the blade assembly has a first blade group 104 and a second blade group 105, and the first blade group 104 is rotatably set on the first air duct 102, and the second blade group 105 is rotatably set on the second air duct 103.

[0061] A first air duct 102 and a second air duct 103 are provided in the shell 1, and the blade assembly has a first blade group 104 and a second blade group 105. The first blade group 104 and the second blade group 105 are both provided with a number of wind-sweeping blades. The total air inlet end 100 is connected with the first air duct 102 and the second air duct 103. The first blade group 104 is rotatably set at the first air outlet 108 of the first air duct 102, and the second blade group 105 is rotatably set at the second air outlet 110 of the second air duct 103. Therefore, when the driving member 4 drives the swing assembly 3 to move, the connecting frame 300 can drive the first blade group 104 and the second blade group 105 to swing at the same time, and the total air inlet end 100 can blow the airflow to the first air duct 102 and the second air duct 103, so as to meet the requirement that the airflow is discharged from the required area.

[0062] As Figure 7 shown in the figure, the two ends of the connecting frame 300 have a first connecting part 306 and a second connecting part 307, the first connecting part 306 is connected with the first blade group 104, and the second connecting part 307 is connected with the second blade group 105.

[0063] The first blade group 104 is composed of a plurality of sweeping blades, and the plurality of sweeping blades are connected by connecting rods, so that the first connecting part 306 is clamped with the connecting rods, and the second blade group 105 is composed of a plurality of sweeping blades, and the plurality of sweeping blades are connected by connecting rods, so that the first connecting part 306 is clamped with the connecting rods, and the connecting frame 300 drives the first blade group 104 and the second blade group 105 to swing during axial movement.

[0064] As Figures 2 to 6 shown in the figure, the air guide assembly 2 has a first driven wheel 200, a second driven wheel 209, a first baffle 201 and a second baffle 202, the driving wheel 400 is engaged with the first driven wheel 200, the first driven wheel 200 is engaged with the second driven wheel 209, the first baffle 201 and the second baffle 202 are located in the shell 1, and the second baffle 202 and the first baffle 201 are hinged, the first baffle 201 can control the opening and closing of the first air duct 102 and the second air duct 103 through the driving part 4, and the first baffle 201 can also push the second baffle 202 through the driving part 4 and cooperate with the second driven wheel 209, so that the second baffle 202 opens and closes the total air inlet end 100.

[0065] The driving wheel 400 is a part of teeth, which can be engaged with the first driven wheel 200, when the driving part 4 rotates the driving wheel 400 to the state that the part of teeth is disengaged from the teeth of the first driven wheel 200, the driving wheel 400 rotates idly, while the first driven wheel remains stationary, the two ends of the second baffle 202 have a circular first mounting part, the two ends of the first baffle 201 have a circular second mounting part, the first mounting part is clamped on the second mounting part, the driving part 4 of the first baffle 201 is connected with the air guide assembly 2, so that the driving part 4 drives the driving wheel 400 to rotate in engagement with the first driven wheel 200, controls the rotation of the first baffle 201 in the shell 1, realizes the separate blocking of the first air duct 102, that is, the conduction of the second air duct 103, or is located between the first air duct 102 and the second air duct 103, that is, makes the first air duct 102 and the second air duct 103 both conductive, or separately blocks the second air duct 103, that is, the first air duct 102 is conductive, or the end surface of the first baffle 201 abuts against the end surface of the second baffle 202, so as to push the second baffle 202 to block the total air inlet end 100, that is, to close the first air duct 102 and the second air duct 103, it should be noted that the part of teeth of the driving wheel 400 can drive the first driven wheel 200 to make the first baffle 201 realize the above-mentioned state.

[0066] As Figures 2 to 6 As shown, the end of the first driven wheel 200 extends outward to form a first clamping portion 401 , the end of the first baffle 201 forms a second clamping portion 203 , and the first clamping portion 401 is connected to the second clamping portion 203 .

[0067] The teeth of the driving wheel 400 are engaged with the teeth of the first driven wheel 200. The end of the first driven wheel 200 extends outward to form a first clamping portion 401, and the end of the first baffle 201 is formed with a second clamping portion 203. The first clamping portion 401 is connected to the second clamping portion 203. When the motor drives the driving wheel 400 to rotate, the driving wheel 400 drives the first driven wheel 200 to rotate, and the first baffle 201 will also rotate synchronously in the shell 1, thereby realizing the above-mentioned first baffle 201 blocking the first air duct 102 and the second air duct 103 and abutting against the second baffle 202.

[0068] like Figure 6 As shown, the second driven wheel 209 is provided with an abutting groove 204 , and the end of the second baffle 202 is provided with a abutting piece 205 , which movably abuts against the abutting groove 204 .

[0069] The tooth portion on the other side of the first driven wheel 200 is engaged with the second driven wheel 209, and the driving wheel 400 reverses to drive the first driven wheel 200 to rotate forward, and the first driven wheel 200 drives the second driven wheel 209 to rotate reversely, so that the end of the first baffle 201 abuts against the end of the second baffle 202, and the first baffle 201 pushes the second baffle 202 to block the total air inlet end 100. At the same time, the resistance member 205 also enters the resistance groove 204 accordingly. When the total air inlet end 100 needs to be opened again, the driving member 4 drives the driving wheel 400 to rotate forward, and the driving wheel 400 drives the first driven wheel 200 to rotate reversely. During the reversal of the first driven wheel 200, the second driven wheel 209 rotates forward and pushes out the resistance member 205 in the resistance groove 204, thereby pushing the second baffle 202 to reset.

[0070] like Figure 6 As shown, a first contact end 210 is provided on the end of the first driven wheel 200, the abutment 205 has a second contact end 206 and a third contact end 207, the abutment groove 204 has a fourth contact end 208, the first contact end 210 and the second contact end 206 are movably abutted against each other, and the third contact end 207 and the fourth contact end 208 are movably abutted against each other.

[0071] Further explanation, that is, Figure 6 and Figure 7, the driving member 4 drives the active wheel 400 to rotate in the opposite direction, so that after the end of the first baffle 201 abuts against the end of the second baffle 202, the first contact end 210 abuts against the second contact end 206, and the second baffle 202 is also pushed to rotate by the first baffle 201, ensuring that the second baffle 202 can block the total air inlet end 100, the first driven wheel 200 rotates to the right, and the active wheel 400 drives the first baffle 201 to rotate to the left, and the first baffle 201 pushes the second baffle 202 to rotate to the left, so that the third contact end 207 is in the abutting groove 204 and abuts against the fourth contact end 208. When the driving member 4 drives the active wheel 400 to reverse, the fourth contact end 208 pushes the third contact end 207 out of the limiting groove, thereby driving the second baffle 202 to reverse and achieve reset.

[0072] The working principle of the single-motor electric air vent structure in the first and second states:

[0073] like Figure 8 and Figure 9 , it is a single-motor electric air vent structure. In the first state, the driving member 4 drives the air guide assembly 2 and the swing assembly 3 to move simultaneously. It can be seen in the figure that the second baffle 202 is against the inner wall of the shell 1, the total air inlet end 100 is connected to the first air duct 102, and the second air duct 103 is blocked by the first baffle 201. At this time, the first blade group 104 and the second blade group 105 are both facing the right side, and the air flow flows into the total air inlet end 100 and flows out from the first air duct 102. The driving member 4 starts and drives the driving wheel 400 to rotate counterclockwise, and the driving wheel 400 drives the first driven wheel 200 engaged therewith to rotate clockwise As the needle rotates, the driving wheel 400 drives the second driven wheel 209 meshing with it to rotate counterclockwise. During the rotation of the first driven wheel 200, the first baffle 201 is driven to rotate clockwise in the housing 1. At the same time, the first connecting rod 402 on the driving wheel 400 moves on the track groove 302 and abuts against the groove surface of the track groove 302, thereby rotating the blade crank 301. The rotating part 303 of the blade crank 301 will drive the toggle block 304 to rotate when it rotates, and then the connecting frame 300 moves outward, driving the first blade group 104 and the second blade to swing gradually from the right side to the left side.

[0074] The driving member 4 then continues to drive the driving wheel 400 to rotate counterclockwise, and the driving wheel 400 drives the first driven wheel 200 meshing therewith to rotate clockwise, and the driving wheel 400 drives the second driven wheel 209 meshing therewith to rotate counterclockwise. During the rotation of the first driven wheel 200, the first baffle 201 is driven to continue to rotate. At the same time, the first connecting rod 402 on the driving wheel 400 continues to move on the track groove 302 and abuts against the groove surface of the track groove 302, thereby driving the blade crank 301 to continue to rotate. When the rotating part 303 of the blade crank 301 rotates, it drives the toggle block 304 to rotate. Figure 10 and Figure 11The first blade group 104 and the second blade group 105 are transformed from the right side state to the vertical state, the first baffle 201 is located between the first air inlet and the second air inlet 109, and the air flow flows into the total air inlet end 100 and flows out from the first air duct 102 and the second air duct 103 respectively.

[0075] The driving member 4 then continues to drive the driving wheel 400 to rotate counterclockwise, and the driving wheel 400 drives the first driven wheel 200 meshing with it to rotate clockwise, and the driving wheel 400 drives the second driven wheel 209 meshing with it to rotate counterclockwise. During the rotation of the first driven wheel 200, the first baffle 201 is driven to continue to rotate. At the same time, the first connecting rod 402 on the driving wheel 400 continues to move on the track groove 302 and abuts against the groove surface of the track groove 302, thereby driving the blade crank 301 to continue to rotate. When the rotating part 303 of the blade crank 301 rotates, it drives the toggle block 304 to rotate. Figure 12 and Figure 13 At this time, the first air duct 102 is blocked by the first baffle 201, and the first blade group 104 and the second blade group 105 both rotate from a vertical state to a left-facing state, and the airflow flows into the total air inlet end 100 and flows out from the second air duct 103.

[0076] The driving member 4 then continues to drive the driving wheel 400 to rotate counterclockwise, and the driving wheel 400 drives the first driven wheel 200 meshing with it to rotate clockwise, and the driving wheel 400 drives the second driven wheel 209 meshing with it to rotate counterclockwise. During the rotation of the first driven wheel 200, the first baffle 201 is driven to continue to rotate. At the same time, the first connecting rod 402 on the driving wheel 400 continues to move on the track groove 302 but does not abut the groove surface of the track groove 302. The blade crank 301 stops rotating, and the first blade group 104 and the second blade group 105 also stop swinging accordingly, and the first driven wheel 200 continues to drive the first baffle 201 to move. Then the driving member 4 drives the driving wheel 400 to rotate counterclockwise. The wheel 400 continues to rotate counterclockwise, the driving wheel 400 drives the first driven wheel 200 meshing with it to rotate clockwise, and the driving wheel 400 drives the second driven wheel 209 meshing with it to rotate counterclockwise. At this time, the first connecting rod 402 on the driving wheel 400 also successively disengages from the right notch of the track groove 302 outward, the swing component 3 stops moving, and the air guide component 2 continues to operate, that is, it is converted from the first state to the second state. When the first baffle 201 rotates to a certain position, it abuts against the second baffle 202. At the same time, the first contact end 210 abuts against the second contact end 206 to push the second baffle 202. The second baffle 202 blocks the total air inlet end 100. Finally, as shown in FIG. Figure 14 and Figure 15 , the airflow cannot enter the air outlet structure, and when the blocking is completed, the third contact end 207 is in the abutting groove and abuts against the fourth contact end 208.

[0077] When the main air inlet end 100 needs to be opened again, the driving member 4 continues to drive the driving wheel 400 to rotate clockwise, the driving wheel 400 drives the first driven wheel 200 engaged therewith to rotate counterclockwise, and the driving wheel 400 drives the second driven wheel 209 engaged therewith to rotate clockwise, and the fourth contact end 208 at the top groove 204 pushes the third contact end 207 on the second baffle 202 to rotate, thereby resetting the second baffle 202, and the main air inlet end 100 is opened, and then the dynamic air outlet structure is converted from the second state to the first state.

[0078] The working principle of the single-motor electric air vent structure in the third state:

[0079] like Figure 9 、 Figure 16 、 Figure 17 and Figure 18 , it is a single-motor electric air outlet structure in the third state. The driving member 4 drives the swing assembly 3 to move alone. It can be seen in the figure that the second baffle 202 is against the inner wall of the shell 1, the total air inlet end 100 is connected to the first air duct 102, and the second air duct 103 is blocked by the first baffle 201. At this time, the first blade group 104 and the second blade group 105 are both facing right, and the air flows into the total air inlet end 100 and flows out from the first air duct 102. The driving member 4 is started and drives the driving wheel 400 to rotate clockwise. Part of the teeth of the driving wheel 400 disengages from the teeth of the first driven wheel 200 to achieve idling, and the first driven wheel 200 remains stationary. At the same time, the second connecting rod 403 on the driving wheel 400 moves on the track groove 302 and abuts against the upper groove surface of the track groove 302, thereby causing the blade crank 301 to rotate. The rotating part 303 of the blade crank 301 will drive the toggle block 304 to rotate when rotating, and the connecting frame 30 0 moves outward, driving the blades on the first blade group 104 and the second blade group 105 from the right side gradually to a vertical state and then swinging toward the left side. During the reset rotation, the driving member 4 starts and drives the driving wheel 400 to rotate counterclockwise, and the driving wheel 400 continues to disengage from the first driven wheel 200 and idles. The first driven wheel 200 remains stationary. At the same time, the second connecting rod 403 on the driving wheel 400 moves on the track groove 302 and abuts against the lower groove surface of the track groove 302, thereby causing the blade crank 301 to rotate in the opposite direction. The rotating part 303 of the blade crank 301 drives the toggle block 304 to rotate when rotating, and then the connecting frame 300 moves inward, driving the blades on the first blade group 104 and the second blade group 105 from the left side gradually to a vertical state and then toward the right side, and then the airflow flowing into the first air duct 102 through the main air inlet end 100 is discharged along the swing direction of the first blade group 104.
