Pouring out the pills: when the pills are poured out through the throat, the pills push the induction rod to move left, the counting gear is separated from the clamping part of the induction rod and rotates under the action of the lower torsion spring, the adjusting rod and the left rotary disc rotate along with the lower torsion spring, and the right rotary disc and the upper torsion spring rotate along with the lower torsion spring. After the pill is poured out, the induction rod moves to the right under the action of the compression spring, so that the right end part of the induction rod is exposed on the inner wall of the throat opening, the clamping part of the induction rod is meshed with the tooth teeth of the counting gear, the adjusting rod, the lower torsion spring, the left turntable, the right turntable, the upper torsion spring and the digital display band stop rotating. When the number of the display belts is zero after being checked from the observation port, the number of the poured pills is the required number of the pills.

Because the rotation of left turn table drives the removal in digital band, the digital band is the circumference surface of winding at the left turn table, after the digital band winding is full left turn table circumference round, when the digital band winding second circle, because the digital band is the surface of winding at first circle digital band, consequently, the left turn table rotates during the same angle, the distance that the digital band removed can increase, when rotating a tooth in order to count the gear, the digital band is just in time for the adjacent numerical value of original numerical value at the numerical value that the viewing aperture shows, consequently, the distance between the adjacent numerical value district of digital band this moment needs to be greater than the distance between the preceding adjacent numerical value.

By adopting the technical scheme, the invention has the beneficial effects that: the invention discloses a medicine bottle cap capable of counting, wherein a cap body is provided with a throat for pouring out pills and an installation groove seat for installing a counting device, and an automatic induction structure is arranged between the throat and the installation groove seat. The user can be as required the pellet quantity of pouring, and the numerical value district in digital band is predetermine to the adjustment hand wheel (the value in this numerical value district equals with pellet quantity), then opens the jam, carries out the pellet action of pouring, and pellet is poured one by one, observes simultaneously, and the digital band is back check decrement in proper order and is 0 until the numerical value in digital band, stops to pour the pellet operation. The automatic pill pouring device is simple in structure and easy and convenient to operate, the problems that too many pills are poured out due to the fact that the pouring quantity of the pills cannot be accurately controlled, the pills are polluted by replacing the medicine bottles again or the pills are thrown away to cause waste can be effectively solved, the pouring quantity of the pills can be accurately preset, and the pills are prevented from being polluted or wasted.
