[0044] Second embodiment

[0045] Please refer to Figure 6 、 Figure 7 、 Figure 8 and Figure 9 Based on the improved funnel-type reflux ratio controller provided in the first embodiment of this application, the second embodiment of this application provides another improved funnel-type reflux ratio controller. The second embodiment is merely a preferred embodiment of the first embodiment, and the implementation of the second embodiment will not affect the independent implementation of the first embodiment.

[0046] Specifically, the difference of the improved funnel-type reflux ratio controller provided in the second embodiment of the present application is that, in an improved funnel-type reflux ratio controller, a connecting hole 17 is opened in the middle of the top of the mounting cover 2, the middle of the inner cavity wall of the connecting hole 17 is connected to the limiting cavity 18, and a spring clip 16 is fixedly connected to one side of the inner cavity wall of the limiting cavity 18.

[0047] The outer surface of the connecting rod 12 is fixedly connected to a rotating block 15 , and the outer surface of the rotating block 15 is fixedly connected to a right-angled tooth block 19 .

[0048] A plurality of right-angled tooth blocks 19 are equidistantly arranged around the outer surface of the rotating block 15. One side of the right-angled tooth block 19 is a right angle, and the other side is an inclined surface. When the inclined surface and the spring 16 are in contact, they are in a natural state. As the right-angled tooth block 19 rotates, the inclined surface squeezes the spring 16, and the spring 16 stretches. When the inclined surface of another right-angled tooth block 19 is in contact with the spring 16, the spring 16 returns to the right angle side of the previous right-angled tooth block 19 to prevent reverse rotation.

[0049] The working principle of an improved funnel-type reflux ratio controller provided by the utility model is as follows:

[0050] During operation, the user first holds the handle 11 to drive the rotating block 4 to rotate, and the rotating block 4 drives the rotating block 15 and the right-angled tooth block 19 to rotate. The inclined surface of the right-angled tooth block 19 squeezes the spring piece 16, and the spring piece 16 is stretched to cause the right-angled tooth block 19 to move. When the spring piece 16 restores its elastic force to press against the right-angled side of the right-angled tooth block 19, the right-angled tooth block 19 cannot rotate in the opposite direction and can only overcome the elastic force of the spring piece 16 to rotate toward the inclined surface.

[0051] Compared with the related art, the improved funnel-type reflux ratio controller provided by the present invention has the following beneficial effects:

[0052] The utility model provides an improved funnel-type reflux ratio controller, which installs a rotating block 15 and a right-angle tooth block 19 on the surface of a connecting rod 12. When a user rotates the connecting rod 12, multiple right-angle tooth blocks 19 are driven to rotate, and cooperate with the spring piece 16, so that the rotating block 4 requires a certain force to rotate in one direction, thereby maintaining the beauty of the surface of the installation cover 2, reducing the complexity of operation, and improving the convenience of operation.
