In this embodiment, the wave groove 8.31 includes two groove walls disposed oppositely: the upper groove wall 8.311 and the lower groove wall 8.312 are located at the peak or trough of the wave groove 8.31, and the protruding part 9.1 is easily maintained to be located at a corresponding position (at a balance position, that is, at a position where the original position is not changed without the active pressing force of the pressing column 9), so that the constant of the closed or opened position is realized, if an elastic resetting part 11 is arranged, the protruding part 9.1 can be abutted against the peak or trough, in another optional embodiment, an adaptive structure can be arranged on the protruding part 9.1, if the protruding part 9.1 is provided with an arc-shaped groove, the arc-shaped groove is completely consistent with the groove wall of the wave groove 8.31 at the peak or trough, and thus the protruding part and the wave groove can be attached to realize stable positioning when the protruding part and the wave groove move to the corresponding position. When the protruding part 9.1 needs to move from the equilibrium position (the closed position or the open position), such as the peak or the trough position, it is likely to move from the upper slot wall 8.311 of the peak or the trough to the lower slot wall 8.312 and can not realize the reciprocating motion between the peak and the trough, in this embodiment, there are at least three methods that can prevent the protruding part 9.1 from simply reciprocating between the upper slot wall 8.311 and the lower slot wall 8.312 of the peak and the trough, one of which is the rotating eccentric protruding part 9.1, specifically, taking the peak as an example, the protruding part 9.1 is an arc part whose shape is consistent with the upper slot wall 8.311 of the peak, but the rotating column is connected with the arc part through a connecting rod, and the connecting rod is eccentrically connected to the arc part, and the connecting rod is rotatably connected with the arc part, optionally, a torsion spring is arranged at the rotating connection position, so that the arc part is attached to the upper slot wall 8.311 to realize the equilibrium position at the peak position, when the pressing column 9, when the arc-shaped part moves from the upper groove wall 8.311 to the lower groove wall 8.312, the connecting rod and the arc-shaped part rotate eccentrically, and the arc-shaped part rotates, so that under the action of the extrusion force of the pressing column 9, the arc-shaped part moves integrally in the eccentric direction and enters the wave groove 8.31 to slide. The trough is also omitted. And the two groove walls of the wave groove 8.31 are arranged in a staggered manner, the two groove walls are staggered by a preset amplitude, namely, the two groove walls are arranged in a staggered manner, the preset amplitude is not more than a quarter wavelength of the wave groove 8.31, namely, the wave crests and the wave troughs of the two groove walls are staggered. At the wave crest or the wave trough position, when the convex part 9.1 moves from one groove wall to the other groove wall, the convex part moves from the wave crest or the wave trough to the non-wave crest or wave trough position, and the non-wave crest or wave trough position can realize sliding by virtue of slope guiding, so that the release of pure reciprocating motion at the balance position is naturally realized. The third is elastic protruding part 9.1, and protruding part 9.1 is the elastic extension structure, is the moving part like both ends, and the centre is provided with the structure of spring, so when through crest or trough position, rely on the spring extrusion to make protruding part 9.1 take place to warp to the aforesaid dislocation structure or eccentric structure of cooperation can be realized the aforesaid motion and relieve.

In another embodiment of the invention, the wave groove 8.31 has two sets (mounting holes 8.3) of crests or troughs with different axial positions, and if two sets of crests with different axial positions, the axial positions of any two adjacent crests are also different, and if two sets of troughs with different axial positions, the axial positions of any two adjacent troughs are also different. The effect of this arrangement is that the adjustment of the opening amplitude of the closure 10 can be achieved by means of peaks or troughs of different heights.

In this embodiment, as a preferred embodiment, the closing member 10 is closed when the protrusion 9.1 is at the position of the upper groove wall 8.311 of the valley, the closing member 10 is opened when the protrusion 9.1 is at the position of the upper groove wall 8.311 of the peak, and the wave grooves 8.31 are arranged in a staggered manner as described above, the shape of the protrusion 9.1 is a structure which is consistent with the shape of the upper groove wall 8.311 of the valley, and the protrusion 9.1 can be constantly maintained at the upper groove wall 8.311 of the valley by means of the elastic member 7, when the protrusion 9.1 is pressed to move from the upper groove wall 8.311 to the lower groove wall 8.312 when movement is required, due to the staggered arrangement, the protrusion 9.1 moves along the lower groove wall 8.312 to the lowest position of the lower groove wall 8.312, when the pressing column 9 is released, the protrusion 9.1 vertically moves from the lower groove wall 8.312 to the upper groove wall 8.311, which is staggered from the balanced position, so as to slide to the peak position, and by means of the elastic force, it can be stably maintained at the upper groove wall 8.311 of the peak, the pressing stud 9 is then pressed, which, due to the misalignment, can move along the wave groove 8.31 to the equilibrium position of the trough, completing a cycle.

In this embodiment, the protrusion 9.1 moves in the wave groove 8.31 to drive the pressing column 9 to move, so as to drive the closing member 10 to move, the opening and closing of the ejection channel 8.2 are realized by the movement of the closing member 10, and the peak or the trough of the wave groove 8.31 can realize the automatic maintenance of the position of the protrusion 9.1, so that the operation is labor-saving.

While certain exemplary embodiments of the present invention have been described above by way of illustration only, it will be apparent to those of ordinary skill in the art that the described embodiments may be modified in various different ways without departing from the spirit and scope of the invention. Accordingly, the drawings and description are illustrative in nature and are not to be construed as limiting the scope of the invention.
