The outer ball 402 and the outer ball cover 409 are fixedly connected and arranged around the inner ball 405 to achieve spherical fit. The handle 401 is inserted into the outer ball 402 and fixedly connected with the outer ball cover 409 . The handle 401 is disposed through the inner ball 405 so that the handle 401 has a degree of freedom to deflect up, down, left, and right relative to the inner ball 405 . Specifically, as shown in Figure 3B, the hook 4011 at the end of the handle 401 abuts against the inner wall surface of the outer spherical cover 409 so that the handle 401 and the outer spherical cover 409 are fixedly connected, and the shift fork 414 is hinged on the outer spherical cover 409, so that The shift fork 414 can rotate relative to the outer spherical cover 409 around the hinge shaft extending in the up-down direction. It should be understood that the articulations herein are by way of example only and not limitation. Returning to Fig. 2B, the shift fork 414 is also connected with the front row blade set 20 to drive the front row blade set 20. As shown in FIG. 3C , the bottom of the inner ball 405 includes a cavity, and one end of the driving tooth 406 is inserted into the cavity for installation. It should be understood that the installation method here is only an example and not a limitation. The other end of the driving tooth 406 has a tooth. Returning to FIG. Blade set 30. In addition, the gear 413 is rotatably mounted on the base 412 (see FIG. 4B ), the pinball 415 is telescopically mounted on the base 412 (see FIG. 4B ) inside the gear 413, and the pinball 415 cooperates with the gear 413 to Provides the feel of the moment the air volume is turned off.

As shown in FIG. 4A , when the handle 401 is in the middle position, the front blades 201 are in the middle position. As shown in FIG. 4B , the outer ball 402 has an axially turned inward spline 4021, the handle 401 fits with the spline 4021, and the inner ball 405 includes a groove, and the groove includes a first groove on the inner wall of the inner ball 405 extending across each other. A groove bottom 4051 and a second groove bottom 4052. When the handle 401 is in the middle position, the spline 4021 is spaced apart from the first groove bottom 4051 and the second groove bottom 4052. It should be understood that the positions of the splines 4021 and the grooves can be reversed, that is, the outer ball 402 is provided with grooves with groove bottoms intersecting each other, while the inner ball 405 is provided with splines. In addition, since the outer ball 402 is fixedly connected with the handle 401 , the spline can also be arranged on the handle 401 .

As shown in Figures 5A-5B, when the handle 401 deflects upward, the handle 401 drives the outer ball 402 to rotate, and at the same time, the spline 4021 moves toward the first groove bottom 4051, and the inner ball 405 remains stationary, so it is connected with the inner ball 405 The shifting tooth 406 also remains motionless, so the rear blade group 30 remains motionless. The upward deflection of the handle 401 also drives the outer spherical cover 409 to rotate downward, and then drives the shift fork 414 connected with the outer spherical cover 409 to swing downward together. The shift fork 414 pushes the front row of blades 201 to turn downward around the front end shaft, so as to realize the function of adjusting the wind direction upward until reaching the upper limit position, at which point the spline 4021 is in contact with the first groove bottom 4051 .

As shown in Figures 6A-6B, when the handle 401 deflects downward, the handle 401 drives the outer ball 402 to rotate, and at the same time, the spline 4021 moves toward the second groove bottom 4052, and the inner ball 405 remains stationary, so it is in contact with the inner ball 405 The connecting teeth 406 also remain motionless, so the rear blade set 30 remains motionless. The downward deflection of the handle 401 also drives the outer spherical cover 409 to rotate upward, and then drives the shift fork 414 connected with the outer spherical cover 409 to swing upward together. The shift fork 414 pushes the front row of blades 201 to turn upward around the front end shaft, thereby realizing the function of adjusting the wind direction downward until reaching the lower limit position, at which point the spline 4021 is in contact with the second groove bottom 4052 .

As shown in FIGS. 7A-7B , when the handle 401 is in the middle position, the rear blades 301 are in the middle position, and the air outlet device is in a fully open state.

As shown in Figures 8A-8C, when the handle 401 deflects to the left, the handle 401 drives the outer ball 402, the inner ball 405 and the shifting teeth 406 to rotate together, and the shifting teeth 406 drives the gear 413 to rotate, and the rear row of blades 301 then rotates to the left Turn to realize the function of adjusting the wind direction to the left until it reaches the left limit position. Wherein, the marble 415 slides over the inner wall of the gear 413 under the action of the elastic force provided by itself. Simultaneously, although the inner ball 405 can rotate with the handle 401 and drive the outer ball cover 409 to rotate, but because the outer ball cover 409 and the shift fork 414 are hinged, the rotation of the outer ball cover 409 will not drive the shift fork 414 to move, so The front row of blades 201 remains stationary. It should be understood that in the embodiment in which the shift fork 414 is not hinged to the outer spherical cover 409, since the horizontal movement range of the shift fork 414 is relatively small, or there is enough space for movement, the movement of the shift fork 414 does not necessarily cause the front row of blades 201 to move. The movement of it can also make the front row of blades 201 remain still.

As shown in Figures 9A-9C, when the handle 401 is deflected to the right, the handle 401 drives the outer ball 402, the inner ball 405 and the shifting tooth 406 to rotate together, and the shifting tooth 406 drives the gear 413 to rotate, and the rear row of blades 301 moves to the right accordingly Rotate to realize the function of adjusting the wind direction to the right. Wherein, the marble 415 slides over the inner wall of the gear 413 under the action of the elastic force provided by itself. Simultaneously, although the inner ball 405 can rotate with the handle 401 and drive the outer ball cover 409 to rotate, but because the outer ball cover 409 and the shift fork 414 are hinged, the rotation of the outer ball cover 409 will not drive the shift fork 414 to move, so The front row of blades 201 remains stationary.

As shown in Figure 10A-Figure 10C, the handle 401 continues to deflect to the right until the toggle 40 is deflected to the third position, the handle 401 drives the outer ball 402, the inner ball 405 and the dial 406 to continue to rotate together, and the dial 406 drives the gear 413 to continue Rotate, the rear blades 301 rotate to the right thereupon until reaching the right limit position, thereby driving adjacent blades 301 to partially overlap at the front and rear, and the air outlet device is in a closed state. At this time, the marble 415 slides into the recess 4131 of the inner wall of the gear 413 under the action of the elastic force provided by itself, so as to provide the feeling of the instant the air volume is turned off.
