The invention discloses an intelligent pushing type drug discharging device, a drug dispensing control system and a drug managing and dispensing method. The intelligent pushing type drug discharging device is used for the intelligent drug dispensing control system and comprises a drug groove used for containing drug and a pushing device used for pushing the drug out of the drug groove. When drug discharging is needed, the pushing device pushes the drug towards the direction of a drug discharging outlet, and the moving length of the pushing device is equal to the length occupied by the drug to be discharged in the drug groove. When drug discharging is not needed, the pushing device does not form pushing force large enough to enable the drug to be pushed out of the drug groove. The intelligent pushing type drug discharging device can be placed at a small angle even zero angle, and is smaller in occupied space and capable of greatly improving the utility rate of space. According to the intelligent pushing type drug discharging device, the foundation of drug discharging counting is reliable, drug stock information can be updated in real time, drug validity date management can be conducted in real time, and maintaining cost is low. Preferably, the pushing device comprises a motor and a pushing component, the middle of the drug groove is hollow to form a channel, and the motor drives a pushing block on the pushing component to make linear reciprocating motion in the channel.

A powered dental tool generally includes a tool tip at its distal end, a body at its proximal end and a motion generating mechanism. In one aspect, the dental tool includes a tool tip having a proximal end and a distal end along a generally longitudinal axis and a reciprocating motion generating mechanism. The reciprocating motion generating mechanism may repeatedly move the tool tip generally back and forth by a given displacement generally along the tool tip's longitudinal axis. This displacement generally resembles the action of a hand scaler, i.e., a reciprocating motion along the longitudinal axis of the scaler, which is unlike the vibration of most powered scalers. Such action may be advantageous as it may be more intuitive for the dental professional or hygienist and may provide more effective scaling action. It may further be advantageous for a powered scaler to more closely resemble a hand scaler in form, which is small, portable and untethered. In one embodiment, the motion generating mechanism may include a rotational source and set of opposing magnetic transfer elements.

The invention relates to a mechanical speed-changing device, in particular to a variable torque type continuously variable transmission. The variable torque type continuously variable transmission realizes infinitely variable speed by changing torque of a speed-changing wheel through a speed-changing control rod. The working principle of the variable torque type continuously variable transmission is that a sliding block with a short shaft is mounted in a groove, in the radial direction, of a speed-changing wheel in the box; an eccentric shaft of a power wheel is connected with the short shaft of the sliding block through a transmission rod; a speed-changing control rod can control movement of the sliding block; the torque of the speed-changing wheel is changed through movement of the sliding block, so that the amplitude of the reciprocating rotation of the speed-changing wheel is changed and the reciprocating stroke of a rack meshed with the speed-changing wheel is changed; the reciprocating motion of the rack is transformed into homodromous rotation by a reversing wheel internally provided with an overrunning clutch; power is output through an output shaft. The radial groove of the speed-changing wheel also can lock the sliding block through isometric pin holes to form speed change with gears. The variable torque type continuously variable transmission is stable in process, large in transmission and suitable for speed change of a main shaft of an engine.
