The first screening plate 3 is fixed above the second screening plate 2, and the baffle 4 is fixed above the first screening plate 3.

As shown in fig. 7, at least part of the structure of the second rim 21 of the second screening plate 2 and at least part of the structure of the first rim 31 of the first screening plate 3 protrude from the guiding side 41 of the baffle 4, the protruding length of the second rim 21 being larger than the protruding length of the first rim 31. The top surface of the second rim 21 may function as a support button.

As shown in fig. 8, the end surface of the first edge 31 is provided with a plurality of first teeth 32 in order along the extending direction thereof to constitute a first tooth surface, and the top surface of the first teeth 32 is gradually inclined downward in a direction approaching the free end thereof. As shown in fig. 12, the front end of the first screening plate 3 is the first edge 31, the top surface of the rear plate surface is the support surface 34, and the support surface 34 may be a flat surface, specifically, may be horizontally provided in the direction in which the first screening plate 3 protrudes from the guide side surface 41, i.e., in the direction indicated by an arrow.

As shown in fig. 3, the screening structure is mounted to the vibration plate 1. When the vibration plate 1 is activated, the button is snapped onto the second edge 21 and the first edge 31 and is advanced against the guide side 41. Wherein, as shown in fig. 9, for the button 6, the front surface is a top surface and the back surface is a bottom surface, the top surface is an upper plane 61, the bottom surface is a lower curved surface 62 protruding downwards, and the button can advance under the support of the first edge 31 and the second edge 21 because the edge of the lower curved surface 62 is tilted and can be adaptively pressed on the inclined first tooth 32; as shown in fig. 10, for the reverse button 5, the reverse side is the top surface, the front side is the bottom surface, the top surface is the upper curved surface, the bottom surface is the lower plane, and after the edge of the lower plane is pressed on the inclined first tooth 32, the lower plane moves and slides downwards in the direction away from the baffle 4 (the left direction in fig. 10) under the inclined guide of the first tooth 32, as shown in fig. 4, under the action of the first tooth 32, the reverse button 5 is further away from the guide side 41 of the baffle 4 than the forward button 6, so that the gravity center of the reverse button 5 also moves synchronously away from the baffle 4, and is turned down by the second edge 21 under the dead weight, and does not move forwards on the second edge 21 continuously, thereby screening and conveying the forward button 6 through the screening structure.

In this embodiment, the button with the front surface being a plane is taken as an example, and the use method of the screening structure is described, and in other embodiments, the front surface of the button may be a surface with a smaller groove in the middle and a plane in the rest, or the front surface may be a curved surface with a smaller radian than the back surface, so that the guiding and pushing effects of the first edge 31 on the reverse button 5 are not affected.

In this embodiment, since the first screening plate 3 has the first edge 31, the top surface of the first edge 31 is inclined, the normal buttons 6 with the convex curved surface on the opposite surface can be continuously conveyed, and the rest buttons fall off, so that the method is suitable for screening buttons with the convex curved surface on the opposite surface.

Further, as shown in fig. 8 and 12, the first teeth 32 are triangular teeth, so that they can more suitably fit the raised portion of the bottom surface of the front button 6 without affecting the contact between the middle portion of the bottom surface of the front button 6 and the second edge 21. Of course, in other embodiments, the first teeth 32 may also be trapezoidal teeth.

Further, as shown in fig. 8, the end face of the second edge 21 is provided with a plurality of second teeth 22 in order along the extending direction thereof to constitute a second tooth surface. By the arrangement of the second tooth surface, the inverted button 5 can be conveniently dropped downward. In addition, the applicability of the screening structure can be increased, for example, the second teeth 22 can also be suitable for screening the buttons shown in fig. 1, and in the case of the size adaptation of the buttons, the forward-placed buttons 6 in fig. 1 can continuously move forward on the second edges 21, and the reverse-placed buttons 5 in fig. 1 after the buttons are inverted, because of the grooves, the surfaces with the grooves cannot be simultaneously lapped on a plurality of the second teeth 22, and can fall from the second edges 21 in a turnover manner. Of course, in other embodiments, the end surface of the second edge 21 may be planar.

Further, as shown in fig. 9, the top surface of the second edge 21 is a plane attached to the bottom surface of the first edge 31, and when in use, the two planes can be horizontally arranged, so that smooth forward movement of the forward button 6 can be ensured, and the stability of the first tooth 32 placed on the second edge 21 can be ensured.

Further, as shown in fig. 8, the second tooth 22 is a triangular tooth, and the free end thereof is a tip, so that the button 5 can fall smoothly at the tip, and of course, in other embodiments, the second tooth 22 may be a trapezoidal tooth.

Further, as shown in fig. 8, the profile height of the second tooth 22 is greater than the profile height of the first tooth 32, and the profile angle of the second tooth 22 is greater than the profile angle of the first tooth 32, so that the top surface of the second tooth 22 can remain a sufficient area except for the portion blocked by the first tooth 32 to stabilize the conveyance for the forward-setting button 6.

Further, as shown in fig. 5 and 6, the lengths of the first screening plate 3 and the second screening plate 2 extending out of the guide side 41 are adjustable, so that screening capability is improved, and the screening structure can be suitable for screening buttons with different reverse radians.
